Description

Technical Field

[0001] This application relates to the field of shoe manufacturing technology, and in particular to a shoe sole branding device for shoe manufacturing. Background Technology

[0002] Shoes, as an important tool to help people walk and effectively protect their feet from injury, have an extremely long history of development, dating back to the Yangshao Culture period more than 5,000 years ago. At that time, the most primitive style of shoes, made of animal hides, had already emerged. Over the long years of evolution, the types of shoes have become extremely diverse. Among them, injection-molded shoes are one type of footwear. The production process of injection-molded shoes is mainly divided into two key parts: the production of the sole and the injection molding of the shoe body. In the sole production process, an indispensable and important step is to brand the shoe size and related icons on the sole of the shoe. This operation must be completed with the help of a professional sole branding device.

[0003] During shoe production, shoe sizes need to be branded onto the bottom of the shoes. After branding, workers need to remove the branded shoes and place new shoes to be branded on top. This operation causes the branding device to be stopped during the changeover, which affects the branding speed and reduces production efficiency. Utility Model Content

[0004] To address the problems mentioned in the background section, this application provides a shoe sole branding device for shoe production, which significantly reduces downtime when changing shoes and greatly improves overall production efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: a shoe sole branding device for shoe production, comprising a base, a replacement component disposed on the top of the inner wall of the base, the replacement component comprising a servo motor, the servo motor being fixedly connected to the top of the inner wall of the base, a connecting shaft being fixedly connected to the transmission end of the servo motor, a first transmission wheel being fixedly connected to the transmission end of the connecting shaft, a transmission belt being drivenly connected to the side surface of the first transmission wheel, a second transmission wheel being drivenly connected inside the transmission belt, the first transmission wheel being drivenly connected to the second transmission wheel via the transmission belt, a rotating sleeve being fixedly connected to the top of the second transmission wheel, a load-bearing fixing plate being fixedly connected to one side of the rotating sleeve, a support being fixedly connected to one side of the load-bearing fixing plate, a support block being connected to the top of the support, a telescopic rod being fixedly connected to the other side of the support block, a return spring being sleeved on the side surface of the telescopic rod, and a spreading rod being fixedly connected to the other side of the telescopic rod.

[0006] Through the above scheme, the servo motor can stably provide power to the replacement components. After the motor starts, the power is transmitted to the first transmission wheel through the connecting shaft, and then the second transmission wheel is driven to rotate through the transmission belt, thereby driving the rotating sleeve and a series of connected components to operate, realizing the switching of shoe workstations and meeting the needs of continuous production.

[0007] Optionally, the rotating sleeve is rotatably connected to a vertical rod, the top of the vertical rod is fixedly connected to a load-bearing plate, the top of the load-bearing plate is fixedly connected to a rotary motor, the transmission end of the rotary motor is fixedly connected to a lead screw, the side surface of the lead screw is threaded with a threaded sleeve, the top of the threaded sleeve is fixedly connected to a horizontal plate, the bottom of the horizontal plate is fixedly connected to a fixing rod, and the bottom of the fixing rod is fixedly connected to a branding plate.

[0008] Through the above solution, the rotary motor can precisely control the rotation of the lead screw. By utilizing the threaded connection between the lead screw and the threaded sleeve, the rotational motion is converted into linear motion, enabling the horizontal plate to drive the branding plate to move up and down, accurately performing the branding operation on the shoe sole, ensuring the consistency of the branding position and depth, and improving product quality.

[0009] Optionally, a load-bearing block is fixedly connected to the other side of the upright, a purification box is fixedly connected to the other side of the load-bearing block, a connecting pipe is fixedly connected to one side of the purification box, an air intake is fixedly connected to one side of the connecting pipe, an exhaust port is opened on the other side of the purification box, and a purification filter is fixedly connected inside the purification box.

[0010] Through the above solution, the purification chamber can play a timely role in the shoe branding process. The suction bucket collects the harmful gases generated and introduces them into the purification chamber through the connecting pipe. The purification filter filters and purifies the harmful gases, and finally the purified gas is discharged from the exhaust port, effectively improving the working environment and ensuring the health and safety of operators.

[0011] Optionally, the diameter of the first transmission wheel is slightly smaller than the diameter of the second transmission wheel, the load-bearing fixing plates are symmetrically distributed, the supports and support blocks are symmetrically distributed, and the number of the spreading rods is four and they are symmetrically distributed.

[0012] Through the above scheme, the difference in diameter between the first and second transmission wheels achieves speed-increasing transmission, which increases torque while reducing rotational speed, ensuring the stability of the load-bearing fixing plate and the shoes it supports during rotation; the symmetrical distribution of the load-bearing fixing plate, support, support block and spreading rod enables the device to fix two shoes and switch work positions at the same time, improving production efficiency.

[0013] Optionally, the servo motor is fixed to the top of the inner wall of the base by bolts, and the connection between the connecting shaft and the transmission end of the servo motor and the first transmission wheel is a fixed connection.

[0014] The above solution facilitates the installation and disassembly of the servo motor and the base by bolting, which is convenient for later maintenance and replacement. The fixed connection between the connecting shaft and the servo motor drive end and the first drive wheel ensures the stability and reliability of power transmission, reduces energy loss during power transmission, and ensures that the entire replacement component can operate stably.

[0015] Optionally, the rotating sleeve is fixed to the top of the second transmission wheel by welding, and the inner wall of the rotating sleeve is provided with a number of balls that are in contact with the outer surface of the upright.

[0016] The above scheme ensures the connection strength between the rotating sleeve and the top of the second transmission wheel by welding, preventing loosening during rotation. The ball bearings on the inner wall of the rotating sleeve contact the outer surface of the upright, greatly reducing rotational friction and making the rotation of the rotating sleeve smoother. This ensures the stability of the workstation switching process and improves the overall operating efficiency and stability of the device.

[0017] Optionally, the suction hopper is funnel-shaped, with an opening area larger than the cross-sectional area of ​​the connecting pipe, and the edge of the suction hopper is provided with a rubber sealing ring.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] 1. This utility model, by setting up a replacement component, allows two shoes to be placed on the support blocks due to their symmetrical distribution. After one shoe is branded, the shoe to be branded can be sent to the bottom of the branding plate through a rotating structure. At the same time, the branded shoe is rotated away from the branding area. Then, the branded shoe is removed from the support block and the shoe to be branded is placed on it. This continuous operation method significantly reduces downtime when changing shoes and greatly improves the overall production efficiency.

[0020] 2. Through the effective combination of the suction hopper and connecting pipe, harmful gases or odors generated during the branding process can be captured in a timely manner, preventing them from spreading in the work area, thereby greatly reducing the risk of workers being exposed to harmful environments and ensuring the safety of the working environment.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The shoe sole branding device for shoe production in this embodiment includes a base 1. A replacement component 2 is provided on the top of the inner wall of the base 1. The replacement component 2 includes a servo motor 201, which is fixedly connected to the top of the inner wall of the base 1. A connecting shaft 202 is fixedly connected to the transmission end of the servo motor 201. A first transmission wheel 203 is fixedly connected to the transmission end of the connecting shaft 202. A transmission belt 204 is driven through the side surface of the first transmission wheel 203. A second transmission wheel 205 is driven through the inside of the transmission belt 204. Wheel 203 is connected to the second transmission wheel 205 via transmission belt 204. A rotating sleeve 206 is fixedly connected to the top of the second transmission wheel 205. A load-bearing fixed plate 207 is fixedly connected to one side of the rotating sleeve 206. A support 208 is fixedly connected to one side of the load-bearing fixed plate 207. A support block 209 is connected to the top of the support 208. A telescopic rod 210 is fixedly connected to the other side of the support block 209. A return spring 211 is sleeved on the side surface of the telescopic rod 210. A spreading rod 212 is fixedly connected to the other side of the telescopic rod 210.

[0030] Please see Figure 1 , Figure 3 and Figure 5 The rotating sleeve 206 is internally connected to a vertical rod 3. The top of the vertical rod 3 is fixedly connected to a load-bearing plate 4. The top of the load-bearing plate 4 is fixedly connected to a rotary motor 5. The transmission end of the rotary motor 5 is fixedly connected to a lead screw 6. The side surface of the lead screw 6 is threaded with a threaded sleeve 7. The top of the threaded sleeve 7 is fixedly connected to a horizontal plate 8. The bottom of the horizontal plate 8 is fixedly connected to a fixing rod 9. The bottom of the fixing rod 9 is fixedly connected to a branding plate 10.

[0031] Please see Figure 1 , Figure 3 and Figure 5 A load-bearing block 11 is fixedly connected to the other side of the upright 3, and a purification box 12 is fixedly connected to the other side of the load-bearing block 11. A connecting pipe 13 is fixedly connected to one side of the purification box 12, and an air intake hopper 14 is fixedly connected to one side of the connecting pipe 13. An exhaust port 15 is opened on the other side of the purification box 12, and a purification filter screen 16 is fixedly connected inside the purification box 12.

[0032] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The diameter of the first transmission wheel 203 is slightly smaller than that of the second transmission wheel 205. The load-bearing fixing plate 207 is symmetrically distributed, the support 208 and the support block 209 are symmetrically distributed, and there are four symmetrically distributed support rods 212. The servo motor 201 is fixed to the top of the inner wall of the base 1 by bolts. The connection between the connecting shaft 202 and the transmission end of the servo motor 201 and the first transmission wheel 203 is fixed. The rotating sleeve 206 is fixed to the top of the second transmission wheel 205 by welding. The inner wall of the rotating sleeve 206 is provided with several balls that are in contact with the outer surface of the upright 3. The suction bucket 14 is trumpet-shaped with an opening area larger than the cross-sectional area of ​​the connecting pipe 13. The edge of the suction bucket 14 is provided with a rubber sealing ring.

[0033] Further explanation is needed: the diameter of the first transmission wheel 203 is slightly smaller than that of the second transmission wheel 205. This design creates a speed-increasing transmission effect. When the servo motor 201 is running, the smaller first transmission wheel 203 drives the larger second transmission wheel 205 through the transmission belt 204, so that the rotational speed of the second transmission wheel 205 is relatively lower than that of the first transmission wheel 203, but the output torque is increased. This helps the load-bearing fixing plate 207 and the shoes it carries to remain stable during rotation, avoiding the shoes from shaking or even falling off the support block 209 due to excessive speed. At the same time, it can also better match the power output of the servo motor 201, achieving efficient and smooth workstation switching.

[0034] The working principle of the above embodiment is as follows: During use, the worker squeezes the expansion rod 212 in the middle, causing the telescopic rod 210 and the return spring 211 to contract under force. Then, the shoe with the branding sole is placed on the support block 209 with the sole facing upward. After completion, the expansion rod 212 is released. The expansion rod 212 serves to fix the shoe. Since the support blocks 209 are symmetrically distributed, two shoes can be placed. The rotary motor 5 is started, and the rotary motor 5 drives the lead screw 6 to rotate. Since the lead screw 6 and the threaded sleeve 7 are connected by threads, the threaded sleeve 7 will move downward along the axis of the lead screw 6. The horizontal plate 8 at the top of the threaded sleeve 7 moves up and down accordingly, and the branding plate 10 also moves up and down synchronously to brand the sole of the shoe on the support block 209 below. When the branding is completed, the rotary motor 5 reverses, the branding plate 10 rises, and returns to the initial position to prepare for branding the next sole.

[0035] Next, once a shoe has been branded, the servo motor 201 is activated. The servo motor 201 drives the first transmission wheel 203 via the connecting shaft 202. The first transmission wheel 203 drives the second transmission wheel 205 to rotate via the transmission belt 204. The rotation of the second transmission wheel 205 causes the rotating sleeve 206 and the load-bearing fixing plate 207 to rotate 180 degrees, rotating the shoe to be branded to below the branding plate 10. The branded shoe is then moved away from the branding area. At this point, the staff removes the branded shoe and places a new shoe on top. By repeating the above steps, downtime can be reduced, and shoes can be branded.

[0036] Finally, during the branding process, some harmful gases or odors may be generated. The purification box 12 draws in these harmful gases through the connecting pipe 13 and the suction hopper 14. The suction hopper 14 is equipped with a rubber sealing ring on its edge, which can fit tightly when close to the work area to prevent exhaust gas leakage. The exhaust gas enters the purification box 12 through the connecting pipe 13. The purification filter 16 fixedly connected inside the purification box 12 filters and purifies the exhaust gas. The purified gas is discharged from the exhaust port 15 on the other side, thereby ensuring the safety and environmental protection of the working environment.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
