[0001] This utility model relates to the field of shoe insole processing technology, specifically to a shoe insole embossing device. Background Technology

[0002] Chinese Utility Model Patent Application No. CN202222720066.0 discloses an embossing device for insole production. The device comprises two sets of fixed plates, multiple sets of support rods, a conveying assembly, and an embossing assembly. The two sets of fixed plates are made of metal, and the multiple sets of support rods are bolted to the top of the fixed plates. The conveying assembly is installed between the fixed plates, and the embossing assembly is installed between the fixed plates and above the conveying assembly. This embossing device for insole production uses a first motor to drive a conveyor belt to rotate intermittently, and a second motor to drive an embossing plate to move intermittently up and down, thereby embossing the insole. However, during operation, the first and second motors need to be repeatedly adjusted to ensure that the frequency of the embossing plate's up and down movement matches the frequency of the conveyor belt's start and stop, making the operation relatively complex.

[0003] Therefore, it is necessary to propose a shoe insole embossing device to solve the above problems. Utility Model Content

[0004] Technical problem to be solved: The purpose of this utility model is to provide a shoe insole embossing device to solve the problem mentioned in the background art that the existing shoe insole production embossing device requires repeated adjustment of motor 1 and motor 2 to make the up-and-down movement frequency of the embossing plate match the start and stop frequency of the conveyor belt, which is relatively complicated to operate.

[0005] Technical Solution: To achieve the above objectives, this utility model provides the following technical solution: A shoe insole embossing device includes a synchronous conveyor belt, an embossing device mounted on the synchronous conveyor belt, and a collection box located below the output end of the synchronous conveyor belt. The embossing device includes an embossing mechanism and multiple lower dies fixedly mounted at intervals on the belt body of the synchronous conveyor belt, with the multiple dies being equidistantly arranged along the length direction of the synchronous conveyor belt body. The embossing mechanism includes a U-shaped frame fixedly mounted above the output end of the synchronous conveyor belt. A sleeve is fixedly mounted on the inner top surface of the U-shaped frame, and a sliding rod is vertically slidably mounted inside the sleeve. A drive ring is fixedly mounted on the lower end of the sliding rod to drive... A top mold is fixedly installed at the bottom of the ring, and a support plate is fixedly installed directly below the top mold. The support plate is located within the enclosed area of ​​the synchronous conveyor belt and abuts against the inner top surface of the synchronous conveyor belt. Rotary disks are rotatably installed on the left and right inner side walls of the U-shaped frame. The two rotating disks are concentrically arranged. A drive rod is movably sleeved inside the drive ring. The two ends of the drive rod are fixedly connected to the two rotating disks respectively, and the drive rod is offset from the center of the rotating disks. A drive motor and an intermittent transmission assembly are provided on one side of the U-shaped frame. The drive motor is connected to the drive roller of the synchronous conveyor belt and one of the rotating disks via the intermittent transmission assembly, and alternately drives the rotating disk and the drive roller of the synchronous conveyor belt to rotate.

[0006] Preferably, the intermittent transmission assembly includes a concentrically arranged rotating ring and a baffle, with the rotating ring located between the U-shaped frame and the baffle. The rotating ring contains three rotating shafts arranged in a triangle, and the two ends of the three rotating shafts are rotatably connected to the U-shaped frame and the baffle, respectively.

[0007] Preferably, an internal gear ring is fixedly fitted inside the rotating ring, and a gear II and an incomplete gear are fixedly fitted at intervals on one of the rotating shafts, while gear I is fixedly fitted on the other two rotating shafts. The incomplete gear and the two gears I are all meshed with the internal gear ring for transmission. The included angle between the first and last teeth of the incomplete gear is less than 180°, and the number of teeth of the incomplete gear is equal to the number of teeth of gear IV.

[0008] Preferably, the drive motor is fixedly installed in the middle of the side of the baffle away from the rotating ring. The output shaft of the drive motor passes through the baffle and is fixedly fitted with gear III. Gear IV is also rotatably fitted on the output shaft of the drive motor. Gear III meshes with gear II for transmission, and gear IV meshes with an incomplete gear for transmission. A connecting ring is concentrically fixedly fitted on the end face of gear IV away from gear III. The other end of the connecting ring passes through the U-shaped frame and is concentrically fixedly connected to one of the rotating disks.

[0009] Preferably, a pulley I is fixedly fitted on the outer side of the rotating ring, and a pulley II is fixedly fitted on one end of the drive roller of the synchronous conveyor belt. The same synchronous belt is fitted on pulley I and pulley II.

[0013] Beneficial effects: Compared with the prior art, this utility model provides a shoe insole embossing device. The shoe insole embossing device has a unique structure and is easy to use. After the drive motor is started, its output shaft drives gear III to rotate. Through gear meshing, gear II and the incomplete gear rotate synchronously. The incomplete gear initially meshes with gear IV and drives it to rotate one revolution. Gear IV drives the rotating disk to rotate through the connecting ring. The drive rod that is off-center rotates around the axis, forcing the drive ring to move vertically downward along the sleeve. Finally, the upper mold and the lower mold close to complete the embossing.

[0014] After the stamping is completed, the incomplete gear disengages from gear IV and engages with the internal gear ring, driving the rotating ring to rotate. The pulley I on the outer side of the rotating ring drives the pulley II of the synchronous conveyor belt through the synchronous belt, causing the synchronous conveyor belt to rotate one station and accurately deliver the next lower die to the stamping position.

[0015] By designing the meshing sequence of incomplete gears and gear IV and internal gear ring, the periodic alternation of "imprinting-conveying" is achieved. The entire process relies on the phase difference of the mechanical structure, eliminating the need for electronic signal synchronization and the need for manual adjustment of the matching of the two sets of motors. The equipment automatically completes the action cycle after startup. In addition, through mechanical meshing transmission, it is ensured that the imprinting interval is strictly matched with the stepping distance of the synchronous conveyor belt, ensuring no cumulative error during long-term operation.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1: This example provides a shoe insole embossing device, which is a direct improvement on existing shoe insole production embossing equipment. It features a unique structure. Please refer to [link / reference]. Figure 1-6 As shown, the device includes a synchronous conveyor belt 1 to avoid cumulative errors during long-term operation, an imprinting device 2 installed on the synchronous conveyor belt 1, and a collection box 3 installed below the output end of the synchronous conveyor belt 1. The imprinting device 2 includes an imprinting mechanism and multiple lower dies 22 fixedly installed at intervals on the belt body of the synchronous conveyor belt 1. The multiple dies are equidistant along the length direction of the belt body of the synchronous conveyor belt 1. The bottom of the lower die 22 has an installation groove, and a rubber block 21 is bolted to the installation groove. The rubber block 21 is bonded to the belt body of the synchronous conveyor belt 1. The lower die 22 is indirectly fixed to the belt body of the synchronous conveyor belt 1 through the rubber block 21. This can avoid the situation where the lower die 22 is directly fixed to the belt body of the synchronous conveyor belt 1. Since the lower die 22 is made of metal, when the belt body of the synchronous conveyor belt 1 passes through the arc area, the belt body will deform while the lower die 22 remains unchanged, which would cause the lower die 22 to detach from the belt body.

[0025] The imprinting mechanism includes a U-shaped frame 23 fixedly installed above the output end of the synchronous conveyor belt 1. The U-shaped frame 23 can be connected to the synchronous conveyor belt 1 in various ways, such as bolting the U-shaped frame 23 to the frame of the synchronous conveyor belt 1. A sleeve 24 is fixedly installed on the inner top surface of the U-shaped frame 23. A sliding rod 25 is vertically slidably fitted inside the sleeve 24. There are multiple sleeves 24, all bolted together with the U-shaped frame 23. By setting multiple sleeves 24, the drive ring 26 is prevented from rotating horizontally, allowing it to move only vertically. The lower end of the sliding rod 25 is fixedly installed with the drive ring 26, and the bottom of the drive ring 26 is fixedly installed with an upper mold 226. The upper mold 226 can be installed in various ways, such as a connecting rod 225 fixedly installed at the bottom of the drive ring 26, with the upper mold 226 fixedly installed at the lower end of the connecting rod 225. A support plate 224 is fixedly installed directly below the 26, and the support plate 224 is located within the enclosed area of ​​the synchronous conveyor belt 1 and abuts against the inner top surface of the synchronous conveyor belt 1. The support plate 224 can provide support for the lower mold 22 and prevent damage to the synchronous conveyor belt 1. Rotary disks 28 are rotatably installed on the left and right inner side walls of the U-shaped frame 23. The two rotating disks 28 are concentrically arranged. A drive rod 27 is movably sleeved inside the drive ring 26. The two ends of the drive rod 27 are fixedly connected to the two rotating disks 28 respectively, and the drive rod 27 is offset from the center of the rotating disks 28. A drive motor 220 and an intermittent transmission assembly are provided on one side of the U-shaped frame 23. The drive motor 220 is connected to the drive roller of the synchronous conveyor belt 1 and one of the rotating disks 28 through the intermittent transmission assembly, and alternately drives the rotating disk 28 and the drive roller of the synchronous conveyor belt 1 to rotate.

[0026] The intermittent transmission assembly includes a concentrically arranged rotating ring 29 and a baffle 219. The rotating ring 29 is located between the U-shaped frame 23 and the baffle 219. Three rotating shafts 213 are provided inside the rotating ring 29, arranged in a triangular pattern. Both ends of the three rotating shafts 213 are rotatably connected to the U-shaped frame 23 and the baffle 219, respectively. The rotating shafts 213 can be installed in various ways, such as by mounting bearing seats 214 at both ends of each rotating shaft 213, with multiple bearing seats 214 bolted together to the U-shaped frame 23 and the baffle 219. The internal fixed assembly includes an internal gear ring 218. One rotating shaft 213 has a gear II 216 and an incomplete gear 217 fixedly mounted at intervals. The other two rotating shafts 213 have gear I 215 fixedly mounted on them. The incomplete gear 217 and the two gears I 215 mesh with the internal gear ring 218 for transmission. The included angle between the first and last teeth of the incomplete gear 217 is less than 180°, and the number of teeth of the incomplete gear 217 is equal to the number of teeth of gear IV 222. When the incomplete gear 217 meshes with gear IV 222, it causes gear IV 222 to rotate one revolution.

[0027] The drive motor 220 is fixedly installed in the middle of the side of the baffle 219 away from the rotating ring 29. The output shaft of the drive motor 220 passes through the baffle 219 and is fixedly fitted with gear III 221. Gear IV 222 is also rotatably fitted on the output shaft of the drive motor 220. Gear III 221 meshes with gear II 216 for transmission, and gear IV 222 meshes with incomplete gear 217 for transmission. A connecting ring 223 is concentrically fixedly fitted on the end face of gear IV 222 away from gear III 221. The other end of the connecting ring 223 passes through the U-shaped frame 23 and is concentrically fixedly connected to one of the rotating disks 28. The other rotating disk 28 is rotatably connected to the U-shaped frame 23 through a bearing. A pulley I 210 is fixedly fitted on the outer side of the rotating ring 29. A pulley II 211 is fixedly fitted on one end of the drive roller of the synchronous conveyor belt 1. The same synchronous belt 212 is fitted on pulley I 210 and pulley II 211.

[0028] Working Principle: When using this equipment for insole embossing, first connect the equipment to an external power source, then start the drive motor 220. The output shaft of the drive motor 220 rotates, driving gear III 221 to rotate. Gear III 221, through meshing transmission, drives gear II 216 to rotate. Gear II 216 synchronously drives the incomplete gear 217 to rotate. Initially, the incomplete gear 217 meshes with gear IV 222, driving gear IV 222 to rotate one revolution. Gear IV 222 drives the connecting ring 223 to rotate, which in turn drives one of the rotating disks 28 to rotate, thereby driving the drive rod 27 to rotate around the axis of the rotating disk 28, thus driving the drive ring 26 to rotate. After repeated up-and-down movements, when the drive ring 26 moves to its lowest point, the upper mold 226 and the lower mold 22 close together, thus imprinting the insole inside the lower mold 22. After imprinting, the incomplete gear 217 meshes with the internal gear ring 218 and drives the pulley I 210 to rotate. The pulley I 210 drives the drive roller of the synchronous conveyor belt 1 to rotate through the belt drive, thereby driving the belt body of the synchronous conveyor belt 1 to rotate, so that the next lower mold 22 moves below the upper mold 226 and repeats the imprinting operation. When the lower mold 22 moves to the output end of the synchronous conveyor belt 1, the lower mold 22 flips downward under the drive of the belt body of the synchronous conveyor belt 1, so that the insole inside the lower mold 22 falls into the collection box 3.

[0029] Example 2: The difference between Example 2 and Example 1 is that the slide rod 25 is a hexagonal prism, and the sleeve 24 is adapted to the slide rod 25, so that the drive ring 26 can only move in the vertical direction.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
