The carriers are located on the worktable and are uniformly spaced apart. Each carrier is configured for holding a workpiece. The heater is configured for heating the workpiece. The cooler is configured for cooling the workpiece. The controller is configured for driving the worktable to rotate, the heater to move down toward and up away from a corresponding one of the carriers, and the at least one cooler to move down toward and up away from another corresponding one of the carriers. At each of successive stages in operation of the hot-melting machine, one of the carriers is aligned with the heater, another one the carriers is aligned with the at least one cooler, and a further one of the carriers is positioned such that a workpiece can be unloaded from the further one of the carriers and another workpiece can be loaded on the further one of the carriers. ## Claims ### Claim 1 A hot-melting machine, comprising: a worktable; a plurality of carriers located on the worktable and being uniformly spaced apart, each carrier configured for holding a workpiece; a heater configured for heating the workpiece; at least one cooler configured for cooling the workpiece, the at least one cooler comprising a driving mechanism and a cooling mold disposed at a bottom end of the driving mechanism, the driving mechanism configured to drive the cooling mold to move down and up, and the cooling mold configured to cool the workpiece and comprising a cooling board and a securing board connecting the cooling board to the driving mechanism, the cooling board defining an exit hole running therethrough, the securing board defining an entrance hole, and the entrance hole and the exit hole cooperatively forming a channel; and a controller configured for driving the worktable to rotate, the heater to move down toward and up away from a corresponding one of the carriers, and the at least one cooler to move down toward and up away from another corresponding one of the carriers, wherein at each of successive stages in operation of the hot-melting machine, one of the carriers is aligned with the heater, another one of the carriers is aligned with the at least one cooler, and a further one of the carriers is positioned such that a workpiece can be unloaded from the further one of the carriers and another workpiece can be loaded on the further one of the carriers. ### Claim 2 (depends on 1) The hot-melting machine as claimed in claim 1, wherein the heater comprises a driving mechanism and a heating board disposed at a bottom end of the driving mechanism, the driving mechanism is configured for driving the heating board to move down and up, and the heating board is configured for heating the workpiece. ### Claim 3 (depends on 1) The hot-melting machine as claimed in claim 1, wherein the cooling board comprises a protrusion, and the protrusion defines at least one exit hole and a plurality of intersecting grooves communicating with the exit hole. ### Claim 4 (depends on 1) The hot-melting machine as claimed in claim 1, wherein the cooling board comprises a recess and a plurality of grooves, the recess has a top surface, the exit hole is defined at the top surface, and at least one of the grooves communicates with the recess. ### Claim 5 (depends on 1) The hot-melting machine as claimed in claim 1, wherein the securing board is generally rectangular, and comprises an upper surface, a lower surface opposite to the upper surface, and four side surfaces connecting the upper surface and the lower surface, and the lower surface is adjacent to the cooling board. ### Claim 6 (depends on 5) The hot-melting machine as claimed in claim 5, wherein the entrance hole is defined at one of the side surfaces of the securing board, and runs through to the lower surface of the securing board. ### Claim 7 (depends on 1) The hot-melting machine as claimed in claim 1, further comprising a frame having a support platform, wherein the heater and the at least one cooler are attached to the support platform. ### Claim 8 (depends on 7) The hot-melting machine as claimed in claim 7, further comprising a protection plate, wherein the protection plate is disposed in a side of the frame adjacent to the heater, the protection plate defines an opening, and at each of the successive stages in operation of the hot-melting machine the further one of the carriers protrudes through the opening. ### Claim 9 (depends on 1) The hot-melting machine as claimed in claim 1, wherein the controller comprises a display device. ### Claim 10 A hot-melting machine, comprising: a worktable;
