Description

Technical Field

[0001] This utility model relates to the technical field of leather shoe production equipment, specifically to a leather surface wrinkle removal device used in leather shoe manufacturing. Background Technology

[0002] Leather shoe manufacturing refers to the production activities of making various leather shoes using leather, artificial leather, or synthetic leather as the upper material and rubber, plastic, or synthetic materials as the outsole, and employing processes such as stitching, gluing, molding, and injection molding. During the production process, a hot press wrinkle-removing machine is often used to remove wrinkles from the leather used on the shoe's surface.

[0003] In the prior art, such as the Chinese patent number CN206077650U "A leather surface wrinkle removal device for leather shoe manufacturing", a body is included, a heating plate is installed on the surface of the body, a pneumatic telescopic rod is installed on the top of the body, a rectangular plate is fixedly installed at the bottom end of the pneumatic telescopic rod, a groove is opened on the surface of the body, and a connecting frame is slidably connected to the surface of the groove.

[0004] In the prior art, as in the aforementioned patent, the connecting frame is moved by a spring, causing the connecting frame to pull and stretch the leather. However, the elasticity of the spring is uncontrollable. When the spring force is small, it cannot effectively stretch the leather, resulting in the inability to remove wrinkles from the leather. When the spring force is large, it will cause a large pulling force on the leather, thereby damaging the leather. Furthermore, it is not convenient to remove wrinkles from the leather during continuous conveying, resulting in low wrinkle removal efficiency. Utility Model Content

A lifting assembly is fixedly installed on the upper end of the processing table. The output end of the lifting assembly is connected to the U-shaped frame. A diversion pipe is fixedly installed above the wrinkle removal plate. The upper end of the diversion pipe is equipped with a transfer pipe, and the lower end of the diversion pipe is equipped with multiple nozzles. Two limiting frames are symmetrically arranged on the left and right sides of the wrinkle removal plate. The two limiting frames are connected by a U-shaped rod. The U-shaped rod is located below the wrinkle removal plate. A propulsion component is fixedly installed at the lower end of the wrinkle removal plate. The output end of the propulsion component is connected to the U-shaped rod. Multiple flattening rollers are symmetrically arranged between the two limiting frames. The flattening rollers are located at the upper end of the wrinkle removal plate, and both ends of the flattening rollers are rotatably connected to the limiting frames.

[0007] To control the tension of the leather fabric, the present invention includes the following improvements: two sets of positioning plates and a second fixing frame are symmetrically arranged on the front and rear sides of the wrinkle-removing plate. The positioning plates are fixed on the wrinkle-removing plate, and a positioning shaft is fixedly arranged at one end of the second fixing frame near the wrinkle-removing plate. The two ends of the positioning shaft are rotatably connected to the positioning plate through bearings. Two pressure detection components are symmetrically arranged at the lower end of the wrinkle-removing plate. The second fixing frame is located above the pressure detection components, and the lower surface of the second fixing frame contacts the detection end of the pressure detection components. The pressure detection components are connected to the control module through electrical signals. The upper surface of the second fixing frame is flush with the upper surface of the wrinkle-removing plate.

[0009] To facilitate assembly of the diversion tube, the present invention includes the following improvement: support rods are provided at both ends of the diversion tube, and the bottom end of the support rods is fixed to the upper end of the first fixing frame by screws.

[0010] To improve the stability of the flattening roller during movement, the present invention includes the following improvements: two guide rails are symmetrically arranged on the left and right sides of the wrinkle-removing plate, the guide rails pass through the limiting frame, and the limiting frame is slidably connected to the guide rails; the cross-section of the guide rails is T-shaped.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a leather surface wrinkle removal device for leather shoe manufacturing, which has the following beneficial effects: This device achieves precise tensioning through a closed-loop control system consisting of a pressure detection component, a control module, and a lifting component. The pressure detection component captures the leather pressure transmitted by the second fixed frame in real time and feeds it back to the control module via an electrical signal. The control module automatically starts and stops the lifting component, and works with the guide rod to ensure the tensioning frame rises and falls smoothly. This keeps the tension of the tensioning roller on the leather within the preset range, avoiding localized stress concentration and completely solving the problem of uncontrolled tension. This ensures both the wrinkle removal effect and prevents damage to the leather.

[0012] This device constructs a continuous conveying system through the coordinated design of "support roller - tension roller - unwinding / rewinding equipment", allowing leather to continuously pass through the wrinkle removal plate working area. At the same time, the propulsion component drives the flattening roller to reciprocate for wrinkle removal and leather conveying in sync, eliminating the need to stop the machine to change the leather area, greatly shortening the single wrinkle removal cycle and meeting the efficiency requirements of batch leather processing in leather shoe production.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model proposes a leather surface wrinkle removal device for leather shoe manufacturing, including a processing table 1, a control module 2 at the upper end of the processing table 1, a control switch 3 on the control module 2, a wrinkle removal plate 10 fixedly installed above the processing table 1, two first fixing frames 11 symmetrically arranged on the left and right sides of the wrinkle removal plate 10, a groove 12 between the wrinkle removal plate 10 and the first fixing frames 11, two support frames 4 symmetrically arranged on the wrinkle removal plate 10 at the upper end of the processing table 1, two support rollers 5 symmetrically arranged on the inner side of the support frame 4, and the two ends of the support rollers 5 rotatably connected to the support frame 4; Two tensioning frames 6 are symmetrically arranged on the front and rear sides of the wrinkle removal plate 10. Two tensioning rollers 7 are symmetrically arranged on the inner side of the tensioning frame 6. The two ends of the tensioning rollers 7 are rotatably connected to the tensioning frame 6. The two tensioning frames 6 are connected by a U-shaped frame 8. The U-shaped frame 8 is located below the wrinkle removal plate 10. A lifting assembly 9 is fixedly arranged on the upper end of the processing table 1. The output end of the lifting assembly 9 is connected to the U-shaped frame 8. A diversion pipe 13 is fixedly installed above the wrinkle removal plate 10. The upper end of the diversion pipe 13 is provided with a transfer pipe 14, and the lower end of the diversion pipe 13 is provided with multiple nozzles 15. Two limiting frames 17 are symmetrically arranged on the left and right sides of the wrinkle removal plate 10. The two limiting frames 17 are connected by a U-shaped rod 19. The U-shaped rod 19 is located below the wrinkle removal plate 10. A pushing component 20 is fixedly arranged at the lower end of the wrinkle removal plate 10. The output end of the pushing component 20 is connected to the U-shaped rod 19. Multiple flattening rollers 18 are symmetrically arranged between the two limiting frames 17. The flattening rollers 18 are located at the upper end of the wrinkle removal plate 10, and both ends of the flattening rollers 18 are rotatably connected to the limiting frames 17.

[0017] The two ends of the diversion pipe 13 are provided with support rods, and the bottom end of the support rods is fixed to the upper end of the first fixing frame 11 by screws.

[0018] 1. Leather conveyor system setup phase: External unwinding equipment and rewinding equipment are respectively installed at the front and rear ends of the processing table 1: After the leather fabric to be wrinkled is unwound by the unwinding equipment, it passes through the support rollers 5 inside the two support frames 4 symmetrically set on the upper end of the processing table 1 and the wrinkle removal plate 10, so that the leather fabric is laid flat on the upper surface of the wrinkle removal plate 10. The leather fabric will be located below the flattening roller 18 on the wrinkle removal plate 10 and will be squeezed by the flattening roller 18. The other end of the leather fabric extends to the winding equipment, which can wind up the wrinkled leather in subsequent operations, forming a continuous conveying path of "unwinding-wrinkling-winding".

[0019] At the same time, the status of the second fixing frame 21 on the front and rear sides of the wrinkle removal plate 10 is confirmed: a positioning shaft 23 is fixed at one end of the second fixing frame 21 near the wrinkle removal plate 10. The two ends of the positioning shaft 23 are rotatably connected to the positioning plate 22 fixed on the wrinkle removal plate 10 through bearings. The lower surface of the second fixing frame 21 is in close contact with the detection end of the pressure detection component 24 symmetrically arranged at the lower end of the wrinkle removal plate 10. The pressure detection component 24 is connected to the control module 2 through an electrical signal and can transmit pressure data in real time.

[0020] 2. Leather tension control stage: Two sets of positioning plates 22 and a second fixing frame 21 are symmetrically arranged on the front and rear sides of the wrinkle removal plate 10. The positioning plates 22 are fixed on the wrinkle removal plate 10. The second fixing frame 21 is fixedly provided with a positioning shaft 23 at one end near the wrinkle removal plate 10. The two ends of the positioning shaft 23 are rotatably connected to the positioning plates 22 through bearings. Two pressure detection components 24 are symmetrically arranged at the lower end of the wrinkle removal plate 10. The second fixing frame 21 is located on the upper end of the pressure detection components 24, and the lower surface of the second fixing frame 21 contacts the detection end of the pressure detection components 24. The pressure detection components 24 are connected to the control module 2 through electrical signals. The upper surface of the second fixing frame 21 is flush with the upper surface of the wrinkle removal plate 10.

[0021] The lower end of the tensioning frame 6 is provided with a guide rod 25 that passes through the processing table 1, and the guide rod 25 is slidably connected to the processing table 1.

[0022] By activating the control switch 3 through the control module 2, the lifting assembly 9 is triggered to operate: the lifting assembly 9 drives the U-shaped frame 8 connected to it to move downward, and the U-shaped frame 8 simultaneously drives the two tensioning frames 6 to slide downward. The tensioning rollers 7 on the inner side of the tensioning frame 6 then exert a downward pulling force on the leather fabric, thereby achieving tensioning of the leather fabric.

[0023] During this process, the leather fabric exerts pressure on the second fixing frame 21. The second fixing frame 21 rotates slightly around the positioning shaft 23 (which cooperates with the positioning plate 22 to achieve rotation buffering), transmitting the pressure to the pressure detection component 24 below. The pressure detection component 24 converts the pressure data into an electrical signal in real time and transmits it to the control module 2. When the control module 2 detects that the pressure value has reached the preset rated range, it automatically controls the lifting component 9 to stop operating, so as to avoid incomplete wrinkle removal due to insufficient tension or damage to the leather due to excessive tension.

[0024] 3. Steam softening and wrinkle removal stage: The external steam delivery equipment is activated by the control module 2: high-temperature steam enters the distribution pipe 13 through the transfer pipe 14. The distribution pipe 13 evenly distributes the steam to several nozzles 15 at the lower end. The nozzles 15 spray high-temperature steam onto the leather fabric on the upper surface of the wrinkle removal plate 10 to soften the leather fabric (reduce the hardness of the leather and facilitate subsequent wrinkle removal).

[0025] Two guide rails 16 are symmetrically arranged on the left and right sides of the wrinkle removal plate 10. The guide rails 16 pass through the limiting frame 17 and are slidably connected to the limiting frame 17. The cross-section of the guide rails 16 is T-shaped.

[0026] After the leather fabric softens, the control module 2 starts the propulsion component 20: the propulsion component 20 drives the U-shaped rod 19 connected to it to move back and forth, and the U-shaped rod 19 simultaneously drives the two limit frames 17 to slide back and forth on the leather fabric along the guide rail 16 (the T-shaped cross section ensures that the limit frames 17 slide smoothly without shaking); Several flattening rollers 18 between the limiting frames 17 move with the limiting frames 17 and roll back and forth on the surface of the leather fabric. The rolling pressure smooths out the wrinkles on the leather surface, achieving a wrinkle removal effect. During this process, the slot 12 between the first fixed frame 11 and the wrinkle removal plate 10 can prevent the limiting frame 17 from interfering with the surrounding components when it slides.

[0027] 4. Continuous cycle wrinkle removal stage: Once the current area of ​​leather wrinkling is completed, the control module 2 coordinates the external unwinding and rewinding equipment to operate synchronously: the unwinding equipment releases the leather fabric to be wrinkled in the next area, and the rewinding equipment simultaneously rewinds the wrinkled leather fabric. With the cooperation of the support roller 5 (continuously guiding) and the tension roller 7 (keeping it taut), the leather fabric moves smoothly to the new working area on the wrinkle removal plate 10.

[0028] The device then automatically repeats the "tension detection - steam softening - flattening and wrinkle removal" process to achieve continuous wrinkle removal of leather fabrics until all leather is processed.

[0029] This device innovatively adopts a composite wrinkle removal method of "steam softening + rolling flattening", which provides uniform and controllable flattening force and avoids local wrinkle residue. At the same time, the cooperation between the limiting frame 17 and the U-shaped rod 19 ensures that multiple flattening rollers 18 move synchronously, so that the wrinkle removal force in each area of ​​the leather is consistent, improving the flatness of the leather surface and meeting the high precision requirements of leather appearance in shoe manufacturing.

[0030] The core control of the device is concentrated in the control module 2 and the control switch 3. Operators do not need to manually adjust the tension or steam volume. They can start, stop or adjust the operating parameters simply by controlling the control switch 3, which lowers the operating threshold.

[0031] Control Module 2 (Central Control Component): Selection recommendation: Industrial-grade PLC controller (such as Siemens S7-200SMART series, Mitsubishi FX3U series); Reasons for selection: Functional adaptation: It needs to simultaneously receive the pressure signal from the pressure detection component 24, control the start / stop and stroke of the lifting component 9, regulate the reciprocating motion of the propulsion component 20, and link with external steam conveying / unwinding / rewinding equipment. The PLC controller has multiple input / output interfaces (digital + analog) to meet the needs of multi-device collaborative control. Environmental adaptability: Industrial-grade PLCs have strong anti-electromagnetic interference capabilities (compliant with GB / T17626 electromagnetic compatibility standards), and can withstand dust in leather shoe workshops and normal temperature environments of 30-40℃, avoiding signal interference; Ease of operation: Supports programming and debugging, and can flexibly set parameters such as pressure rating range and propulsion component stroke 20, adapting to the wrinkle removal needs of leathers of different thicknesses (such as cowhide and sheepskin), with low maintenance costs.

[0032] Control switch 3 (human-machine interface component): Selection recommendation: Industrial waterproof and dustproof push button switches (such as Schneider XB2 series, ABBMCB series). Reasons for selection: Durability: Due to frequent operation in the workshop, switches with a mechanical life of ≥100,000 cycles should be selected to avoid frequent replacements; Protection rating: Select IP65 or higher protection rating to prevent dust and small amounts of oil generated during leather processing from entering the switch and avoid short circuit failure; Functional compatibility: It must include buttons such as "Master Start / Stop", "Individual Control of Lifting Component 9", "Individual Control of Propulsion Component 20", and "Emergency Stop". The emergency stop button adopts a red mushroom head design, which complies with safety regulations and can quickly cut off the power supply to the equipment in case of emergency.

[0033] Lifting assembly 9 (tensioning frame 6 drive component): Recommended selection: Industrial-grade electric linear actuators (such as Thomson Electrak series and Evelli IL series); Reasons for selection: Precise control: It needs to start and stop according to the signal of the pressure detection component 24. The electric push rod supports adjustable stroke (such as 50-200mm, to adapt to different tensioning frame 6 lifting requirements) and has a position feedback function (such as potentiometer feedback). It can be linked with the control module 2 to achieve "stop when the pressure reaches the standard" to avoid over-tensioning and damaging the leather. Load adaptability: The thrust required for leather tensioning is relatively small (about 500-1000N), which can be met by a small electric push rod. It is also compact and can be directly fixed on the upper part of the processing table 1 without taking up too much space. Stability: The electric linear actuator operates with low noise (≤60dB), making it suitable for workshop environments. It also eliminates the need for pneumatic / hydraulic pipelines, thus avoiding pipeline leakage failures.

[0034] Propulsion assembly 20 (reciprocating drive component of flattening roller 18): Selection recommendation: Precision linear modules (such as HIWINKK series, THKKR series); Reasons for selection: Motion accuracy: The pressing roller 18 needs to be driven to reciprocate smoothly along the guide rail 16. The positioning accuracy of the linear module can reach ±0.02mm to avoid uneven wrinkle removal caused by the offset of the pressing roller 18. Speed ​​adaptation: After the leather is softened, wrinkle removal requires a low and stable speed (reciprocating speed 0.1-0.5m / s). The linear module supports stepless speed adjustment, and the rolling speed can be set to match different leathers through the control module 2. Structural compatibility: The linear module can be directly fixed to the lower end of the wrinkle removal plate 10, and the output end is firmly connected to the U-shaped rod 19. It also has a dust cover (optional) to prevent workshop dust from entering the module and affecting its lifespan.

[0035] Pressure detection component 24 (tension feedback component): Selection recommendation: Miniature pressure sensors (such as Honeywell 24PC series, Fujikura FPM series); Reasons for selection: Range adaptation: The pressure range of the leather on the second fixing frame 21 is small (about 0-50N). The miniature pressure sensor with a range of 0-100N is sufficient, and the accuracy can reach ±1%FS, ensuring accurate pressure detection. Installation and fitting: Compact size (diameter ≤ 20mm, thickness ≤ 5mm), can be embedded at the lower end of the wrinkle removal plate 10 and the contact point with the second fixing frame 21 without affecting the rotation of the second fixing frame 21; Signal adaptation: Outputs a 4-20mA standard analog signal, which can be directly connected to the analog input interface of control module 2. The signal transmission is stable and has no delay.
