Description

Technical Field

[0001] This utility model relates to the field of shoe material processing technology, specifically to a precision positioning hot stamping machine for shoes. Background Technology

[0002] Hot stamping is one of the key processes for achieving decoration, branding, and personalized design on footwear products.

[0003] Traditional hot stamping machines for footwear typically include a frame, a hot stamping die mounted on the frame, a drive mechanism for raising and lowering the hot stamping die, and a worktable for placing footwear materials.

[0004] The workflow is as follows: the operator covers the area to be processed on the shoe material with hot stamping foil, then manually places the shoe material on the workbench, starts the equipment, and the hot stamping die head presses down, transferring the pattern on the hot stamping foil to the surface of the shoe material through heat and pressure.

[0005] Existing technologies have made many improvements to hot stamping equipment. For example, Chinese patent CN220742481U discloses an automatic hot stamping machine for shoe manufacturing, including a base plate, a belt conveyor, and a label hot stamping machine. The base plate has four fixed support columns around its top, and a top plate is fixedly connected between the tops of the four support columns. Two electric lifting rods are evenly fixedly connected from front to back on one side of the bottom of the top plate. A mounting frame is fixedly connected between the output ends of the two electric lifting rods. By activating the four electric push rods inside the hot stamping assembly, the positioning frame and lifting plate are simultaneously moved downwards, activating the hot press plate to hot-press and reinforce the hot stamping label affixed to the top of the shoe product. After hot stamping is completed, the electric push rods are turned off, causing the hot press plate to move upwards. While moving upwards, the positioning frame is still subjected to the rebound force of the compression spring, positioning and fixing the shoe product. This prevents the hot press plate from lifting the shoe product due to the excess adhesive on the hot stamping label, thus improving the efficiency of hot stamping processing for shoe products.

[0006] However, it still has the following shortcomings in actual use:

[0007] 1. Hot stamping efficiency is low; automatic hot stamping machines for shoemaking require intermittent stops to achieve hot stamping under pressure.

[0008] 2. The material loading relies on manual loading, which is costly and cannot guarantee the accuracy of positioning.

[0009] Based on this, this utility model designs a precise positioning hot stamping machine for shoes to solve the above problems. Utility Model Content

[0048] like Figure 7As shown, hot stamping foil starts from the hot stamping foil roll on the hot stamping foil feeding roller 201 and is sequentially wound around the outer walls of the hot stamping foil feeding roller 201, the hot stamping pressure roller 202, the traction roller 203, the tension roller 204 and the hot stamping foil waste column.

The adjusting threaded post 212 can be fixed to the adjusting fixing plate 211 by a nut.

[0050] In this invention, when feeding footwear 5, when the loading / unloading push rods 106 and loading / unloading fixing plates 107 on the base frame 101 and base plate 102 move to above the lower top plate 117 via the linear module 103, the double-rod cylinder 104 is activated, pushing the connecting plate 105, loading / unloading push rods 106, and loading / unloading fixing plates 107 downwards, thereby causing the needle suction cup 109 to move downwards and adsorb and grab the footwear 5 on the lower top plate 117. Simultaneously, the double-rod cylinder 104 is activated, causing the needle suction cup 109 and the footwear 5 on it to move upwards. At the same time, the loading / unloading push rod 106 is activated, and with the cooperation of the slide rod 110 and the limiting block 111, the footwear 5 is... The loading and unloading moving plate 108 moves to the position of the loading and unloading fixed plate 107. When the loading and unloading fixed plate 107 and the loading and unloading moving plate 108 move to the top of the belt conveyor 3, the double-rod cylinder 104 is activated to push the loading and unloading fixed plate 107 and the loading and unloading moving plate 108 downward, placing the gripped footwear products 5 on the belt of the belt conveyor 3. After placement, the double-rod cylinder 104 is activated to reset the loading and unloading fixed plate 107 and the loading and unloading moving plate 108. The loading and unloading push rod 106 is activated to reset the loading and unloading fixed plate 107 and the loading and unloading moving plate 108. This enables precise positioning and dense arrangement of the footwear products 5 during loading.

[0051] When the topmost footwear product 5 is picked up and carried away by the needle suction cup 109, the motor 112 on the power base 116 starts, driving the threaded rod 113 to rotate, thereby driving the moving plate 115 to move upward. The power limiting post 114 plays a limiting role. With the cooperation of the limiting post 118, the protrusion of the moving plate 115 drives the lower top plate 117 to move upward, thereby lifting the footwear product 5 below to the highest position to wait for picking and loading.

[0052] After the footwear products 5 on the two sets of lower top plates 117 in front are loaded, the station switching push rod 121 on the station switching base 122 is activated. With the cooperation of the slide rail 120, the station switching moving plate 119 moves forward, causing the two sets of lower top plates 117 in the rear to move forward until the lower top plate 117 in the rear abuts against the protrusion on the moving plate 115. This allows for uninterrupted loading without stopping the machine.

[0053] When the hot stamping motor 213 is started, with the cooperation of the hot stamping paper feeding roller 201, hot stamping pressure roller 202, traction roller 203, tension roller 204 and hot stamping paper waste roller 205, the footwear products 5 on the belt conveyor 3 will be hot stamped when they are transported to the area below the hot stamping pressure roller 202. With the cooperation of the moving groove 207, the hot stamping pressure roller 202 can automatically tension the hot stamping paper due to its own weight and the elasticity of the spring 208. When it is necessary to increase the tension of the hot stamping paper, it is only necessary to move the position of the adjusting block 209 down so that the adjusting threaded column 212 moves down in the adjusting groove 210. The adjusting groove 210 and the adjusting threaded column 212 are fixed by the nut, which will compress the spring 208 and increase the tension of the hot stamping pressure roller 202.

[0054] When the hot stamping finished footwear product 5 moves to the left end of the belt conveyor 3, the multi-station automatic loading and unloading mechanism 1 located at the left end of the belt conveyor 3 can accurately position and unload the footwear product 5, and the action is the same as when loading.

[0055] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
