Abstract

A fine texture forming device for shoe sole surfaces, relating to the technical field of shoe sole processing equipment, includes a worktable, a rotating base, a fixing device, a hot roller pressing device, and a control device. The shoe sole is placed on the rotating base, and the fixing device clamps the shoe sole onto the rotating base. The hot roller pressing device drives the base to move via a drive mechanism, thereby moving a metal mesh roller. The metal mesh roller is heated by a thermal radiation heater to roll the side of the shoe sole. The control device includes a first temperature sensor, a second temperature sensor, a rotary motor, and a controller. By setting the first and second temperature sensors on the front and rear sides of the metal mesh roller, the temperature of the metal mesh roller is kept stable. By monitoring the temperature difference fed back by the two sensors, the controller can control the rotation of the metal mesh roller to maintain uniform heating. This eliminates the need to manufacture expensive dense molds and avoids inconsistent texture forming due to uneven temperature during rolling.

Description

Technical Field

[0001] This invention belongs to the field of shoe sole processing equipment, specifically a shoe sole surface fine texture forming equipment and its rolling method. Background Technology

[0002] ETPU is a type of TPU material that is formed into beads through supercritical foaming. Because its shape resembles popcorn, the midsole of sports shoes made of ETPU is called popcorn midsole. It has advantages such as excellent resilience, extremely low compression permanent deformation, good wearing experience, and environmentally friendly and efficient processing.

[0003] Existing popcorn-patterned shoe soles, after production, exhibit irregular, granular dark patterns on their surface. This repetitive texture leads to consumer fatigue and negatively impacts the shoe's overall design. Therefore, there is a real need within the industry to eliminate these granular dark patterns on popcorn-patterned shoe soles. Current solutions involve creating dense textures on the inner wall of a mold to cover the surface patterns until they are no longer visible to the naked eye. However, the molds used for these dense textures require high-precision metal 3D printing, which is significantly more expensive than traditional machined metal molds, making this solution impractical for the market. The challenge of this project is to design a new, low-cost solution to cover the granular dark patterns on popcorn-patterned shoe soles. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for forming fine textures on the surface of shoe soles and a rolling method thereof.

[0005] The present invention adopts the following technical solution:

[0006] A fine texture forming device for shoe sole surfaces includes a worktable, a rotating seat, a fixing device, a hot roller pressing device, and a control device.

[0007] The rotating seat is rotatably mounted on the worktable and is used to hold shoe soles.

[0008] The fixing device is set on the worktable opposite to the rotating seat, and the two form a clamping station for clamping the shoe sole;

[0009] The hot roll pressing device includes a base, a metal mesh roller, and a thermal radiation heater. The base is set on the worktable and can be moved away from or close to the clamping station. The metal mesh roller can be rotated around its own axis and is set on the base facing the clamping station, with its rotation axis perpendicular to the worktable. The thermal radiation heater is set on the base and faces the metal mesh roller to heat the metal mesh roller.

[0010] The control device includes a first temperature sensor, a second temperature sensor, a rotary motor, and a controller. The first temperature sensor and the second temperature sensor are respectively located on both sides of the metal mesh roller. The rotary motor is located on the worktable and drives the metal mesh roller to rotate. The controller controls the rotation of the rotary motor and controls the operation of the thermal radiation heater based on the signals fed back by the first temperature sensor and the second temperature sensor.

[0011] Preferably, the hot rolling device further includes a driving mechanism, which includes an electric slide table and a servo motor. The electric slide table is disposed on the worktable, and the base is disposed on the electric slide table. The servo motor is connected to the electric slide table and drives the electric slide table to move the base back and forth to drive the metal mesh roller to roll and press the shoe sole.

[0012] Preferably, the control device further includes a rotational torque sensor disposed between the servo motor and the electric slide table. The servo motor is connected to the controller, and the servo motor is controlled to work according to the signal fed back by the rotational torque sensor. When the sole rotates with the rotating seat, the metal mesh roller is controlled to always press against the side of the sole with the same force.

[0013] Preferably, the fixing device includes a bracket, a telescopic cylinder, a magnetic sleeve, a limiting protrusion, and a limiting inner edge. The bracket is set on the worktable and located above the rotating seat. The telescopic cylinder is set on the bracket and opposite the rotating seat. The piston rod of the telescopic cylinder can extend downward through the bracket to approach the rotating seat. The magnetic sleeve is sleeved on the end of the piston rod and can move downward with it to approach the rotating seat. The limiting protrusion extends outward from the end of the piston rod. The limiting inner edge extends inward from the top of the magnetic sleeve and can contact the top surface of the limiting protrusion. An electromagnet is set on the rotating seat, and a magnet is set at the bottom of the magnetic sleeve. When the electromagnet is energized, the magnetic sleeve can clamp the sole between the two and rotate with the rotating seat. The diameters of the electromagnet and the magnetic sleeve are both smaller than the narrowest part of the sole.

[0014] Preferably, the inner diameter of the limiting inner edge is greater than the diameter of the piston rod and less than the outer diameter of the limiting protrusion.

[0015] Preferably, the base includes a slider, an extension section, a balance section, and a counterweight. The slider is movably mounted on the electric slide table. The extension section extends outward from the slider along the side near the clamping station. The metal mesh roller and the thermal radiation heater are mounted on the extension section. The balance section is formed on the slider in the opposite direction to the extension section. The counterweight is mounted on the balance section to balance the base.

[0016] Preferably, the workbench is also equipped with an isolation cabinet and an operation panel. The controller is located in the isolation cabinet and connected to each component. The isolation cabinet is also equipped with a power supply connected to the thermal radiation heater and the servo motor, and an air circuit system connected to the telescopic cylinder.

[0017] Preferably, the metal mesh roller includes a soft roller core connected to the rotary motor and a metal mesh sleeve fitted on the outside of the soft roller core, with the top of the metal mesh sleeve fixed to the top surface of the soft roller core and the bottom hanging freely on the outside of the soft roller core.

[0018] A method for hot rolling out shoe sole texture, comprising the shoe sole surface fine texture forming equipment described in any one of the above claims, wherein the method is as follows:

[0019] (1) Preheat the metal mesh roller, start the thermal radiation heater, and the controller controls the rotary motor to work according to the signals fed back by the first temperature sensor and the second temperature sensor, driving the metal mesh roller to rotate to maintain uniform heating.

[0020] (2) Maintain temperature: Based on the signals fed back by the first temperature sensor and the second temperature sensor, the controller controls the power of the thermal radiation heater to maintain the temperature of the metal mesh roller stable.

[0021] (3) Install the sole, place the sole on the rotating seat, and control the fixing mechanism to clamp the sole in the clamping position;

[0022] (4) Start rolling. The rotating seat rotates and drives the shoe sole to rotate, so that the metal mesh roller always presses against and rolls on the side of the shoe sole to perform texture hot pressing.

[0023] As can be seen from the above description of the present invention, compared with the prior art, the beneficial effects of the present invention are: after the metal mesh roller is heated by the thermal radiation heater, the side of the foamed shoe sole is hot-rolled to form a fine texture, covering the dark texture formed by popcorn particles. There is no need to make expensive dense molds. At the same time, by setting a first temperature sensor and a second temperature sensor on the front and rear sides of the metal mesh roller, the temperature of the metal mesh roller is kept stable. The controller can control the rotation of the metal mesh roller according to the temperature difference fed back by the two sensors to keep the heating uniform and avoid inconsistent texture forming due to uneven temperature during the rolling process.

[0024] The electric slide table, in conjunction with the servo motor, can precisely control the movement of the metal mesh roller, thereby improving the texture quality of the roller pressed onto the side of the shoe sole.

[0025] A rotary torque sensor is used to control and stabilize the pressure of the metal mesh roller against the sole. When the metal mesh roller moves closer to the sole and contacts it, the resistance of the electric slide increases, and the torque of the internal screw changes. The controller can control the servo motor to drive the electric slide to stop at the position corresponding to the preset torque for rolling. When the sole rotates, the torque increases or decreases. The controller controls the electric slide to drive the metal mesh roller forward or backward to maintain a stable torque, so as to achieve constant pressure of the metal mesh roller on the side of the sole and improve the quality of the rolled texture.

[0026] The magnetic sleeve moves downward to above the sole via a telescopic cylinder, attracts the electromagnet, and clamps the sole between them. At this time, the telescopic cylinder does not directly contact the sole; the sole is only attracted downward by the magnetic sleeve. The magnetic sleeve can rotate around the piston rod. Compared to pressing the sole directly with the cylinder, this effectively avoids the friction generated by pressing, which could cause the sole to slip off the rotating seat when it rotates. When the piston rod retracts, it can also move the limiting protrusion upward through the inner edge of the limiting position to separate the magnetic sleeve from the sole.

[0027] The inner diameter of the limiting inner edge is larger than the diameter of the piston rod and smaller than the outer diameter of the limiting protrusion, so that the telescopic cylinder does not need to be matched with the rotating seat with extremely high assembly precision when it is installed, allowing for a large coaxiality deviation between the two, reducing assembly requirements and assembly difficulty.

[0028] Since the metal mesh roller needs to be close to the clamping station for rolling, the position of the metal mesh roller needs to be extended outward to the outside of the electric slide table. Therefore, it is necessary to install a counterweight to balance the slider and avoid the center of gravity shift from affecting the movement of the slider.

[0029] The metal mesh sleeve has a certain degree of elasticity and hangs down on the outside of the soft roller core. When the soft roller core presses the metal mesh sleeve onto the side of the shoe sole, the dense texture of the metal mesh sleeve is pressed onto the shoe sole, making it less likely for the shoe sole to deform and further improving the quality of the product.

Detailed Implementation

[0038] The present invention will be further described below through specific embodiments.

[0039] Reference Figures 1 to 7 As shown, a fine texture forming device for shoe sole surface includes a worktable 1, a rotating seat 2, a fixing device 3, a hot roller pressing device 4, and a control device 5.

[0040] The rotating seat 2 is rotatably mounted on the workbench 1. A metal electromagnet 21 is mounted on the rotating seat 2, and the shoe sole is placed on the electromagnet 21.

[0041] The fixing device 3 is mounted on the worktable 1 opposite to the rotating seat 2, forming a clamping station for holding the shoe sole. The fixing device 3 includes a bracket 31, a telescopic cylinder 32, a magnetic sleeve 33, a limiting protrusion 34, and a limiting inner edge 35. The bracket 31 is mounted on the worktable 1 and located above the rotating seat 2. The telescopic cylinder 32 is mounted on the bracket 31 opposite to the rotating seat 2. The piston rod 36 of the telescopic cylinder 32 can extend downward through the bracket 31 to approach the rotating seat 2. The stroke length of the piston rod 36 of the telescopic cylinder 32 should be greater than the distance from the bracket 31 to the rotating seat 2. The magnetic sleeve 33 is sleeved on the piston rod 36. The end can move downwards to approach the rotating seat 2; the limiting protrusion 34 extends outwards from the end of the piston rod 36; the limiting inner edge 35 extends inwards from the top of the magnetic sleeve 33 and can contact the top surface of the limiting protrusion 34. The inner diameter of the limiting inner edge 35 is larger than the diameter of the piston rod 36 and smaller than the outer diameter of the limiting protrusion 34, so that the telescopic cylinder 32 does not need to be matched with the rotating seat with extremely high assembly precision when it is installed, allowing for a large coaxiality deviation between the two, reducing assembly requirements and assembly difficulty. The magnetic sleeve 33 moves downward to above the sole via the telescopic cylinder 32 and attaches the sole to the electromagnet 21 of the rotating seat 2. At this time, the telescopic cylinder 32 is not in direct contact with the sole. The sole is only attracted by the downward force of the magnetic sleeve 33 being attracted by the electromagnet 21. The magnetic sleeve 33 can rotate around the piston rod 36. Compared with pressing the sole directly with the cylinder, this can effectively avoid the friction generated by pressing causing the sole to slip off the rotating seat 2 when it rotates. When the piston rod 36 retracts, it can also drive the limiting protrusion 34 to move upward via the limiting inner edge 35 to separate the magnetic sleeve 33 from the sole.

[0042] Specifically, a magnet 37 is provided at the bottom of the magnetic sleeve 33. The magnetic sleeve 33 can clamp the sole of the shoe onto the electromagnet 21 and rotate with the rotating seat 2. The diameters of both the electromagnet 21 and the magnetic sleeve 33 are smaller than the narrowest part of the sole of the shoe, so as to avoid the sole of the shoe being blocked by the electromagnet 21 or the magnetic sleeve 33, thus preventing the metal mesh roller 42 from rolling the position.

[0043] The hot roll forming device 4 includes a base 41, a metal mesh roller 42, a drive mechanism 43, and a thermal radiation heater 44. The base 41 is mounted on the worktable 1 and moves back and forth in a direction away from or near the clamping station. The metal mesh roller 42 is mounted on the base 41 and can be opposite to the clamping station, with its rotation axis perpendicular to the worktable 1. The drive mechanism 43 is mounted on the worktable 1 and drives the base 41 to move back and forth. The thermal radiation heater 44 is mounted on the base 41 and is opposite to the metal mesh roller 42, continuously heating the metal mesh roller 42. After the metal mesh roller 42 is heated by the thermal radiation heater 44, the side of the foamed shoe sole is hot rolled to form a new texture, eliminating the need to make expensive dense molds.

[0044] Specifically, the base 41 includes a slider 411, an extension section 412, a balance section 413, and a counterweight 414. The slider 411 is movably mounted on the electric slide table 431. The extension section 412 extends from the slider 411 along the side near the clamping station. The metal mesh roller 42 and the thermal radiation heater 44 are mounted on the extension section 412. The balance section 413 is mounted on the slider 411 in the opposite direction to the extension section 412. The counterweight 414 is mounted on the balance section 413 to balance the base 41. Since the metal mesh roller 42 needs to be close to the clamping station for rolling, the position of the metal mesh roller 42 needs to extend outward to the outside of the electric slide table 431. Therefore, it is necessary to install the counterweight 414 to balance the slider 411 and avoid the center of gravity shift from affecting the movement of the slider 411.

[0045] Furthermore, the drive mechanism 43 includes an electric slide 431 and a servo motor 432. The electric slide is mounted on the worktable 1, and the base 41 is mounted on the electric slide 431. The servo motor 432 is connected to the electric slide 431 and drives the electric slide 431 to move the base 41 back and forth.

[0046] The control device 5 includes a first temperature sensor 51, a second temperature sensor 52, a rotary motor 53, and a controller. The first temperature sensor 51 and the second temperature sensor 52 are respectively disposed on both sides of the metal mesh roller 42. The rotary motor 53 is disposed on the base 41 to drive the metal mesh roller 42 to rotate, ensuring uniform heating. The controller controls the rotation of the rotary motor 53 and controls the operation of the thermal radiation heater 44 based on the signals fed back from the first temperature sensor 51 and the second temperature sensor 52. The controller is a common PLC control unit in the prior art, and its control system and control method are common technical means in the prior art, and are not the focus of this application, so they will not be described further here. By setting the first temperature sensor 51 and the second temperature sensor 52 on the front and rear sides of the metal mesh roller 42, the temperature of the metal mesh roller 42 is kept stable. At the same time, by monitoring the temperature difference fed back by the two sensors, the controller can control the rotation of the metal mesh roller 42 to maintain uniform heating and avoid inconsistent texture formation due to uneven temperature during roll pressing. During the roll forming process, the rotary motor 53 is in a stopped state, and the metal mesh roller 42 is in a state of free rotation. At this time, the metal mesh roller 42 contacts the outer side of the shoe sole and rolls on the outer side of the shoe sole under the action of friction, thereby completing the texture roll forming.

[0047] Specifically, the metal mesh roller 42 includes a soft roller core 421 connected to a rotary motor 53 and a metal mesh sleeve 422 sleeved on the outside of the soft roller core 421. The top of the metal mesh sleeve 422 is fixed to the top surface of the soft roller core 421 and the bottom hangs freely on the outside of the soft roller core 421. The soft roller core 421 and the metal mesh sleeve 422 have a certain elasticity. When the soft roller core 421 presses against the side of the shoe sole, the dense texture of the metal mesh sleeve 422 is rolled onto the shoe sole, which makes it less likely for the shoe sole to deform, thereby further improving the quality of the product.

[0048] Furthermore, the control device 5 also includes a rotational torque sensor disposed between the servo motor 432 and the electric slide 431. The servo motor 432 is connected to the controller, and the controller operates the servo motor 432 based on the signal fed back by the rotational torque sensor. When the sole rotates with the rotating base 2, the metal mesh roller 42 is controlled to always press against the side of the sole with the same force. The rotational torque sensor is used to control the pressure of the metal mesh roller 42 against the sole and keep it stable. In use, the force applied by the metal mesh roller 42 to the side of the sole is preset and input into the controller, which converts it into the torque generated when the electric slide 431 moves. When the sole rotates, increasing the linear distance from the side of the sole to the metal mesh roller 42 (i.e., the side of the sole opposite the metal mesh roller 42 rotates from the front and back ends to the left and right sides), the resistance on the metal mesh roller 42 decreases. At this time, the electric slide 431 tends to rotate in the forward direction to drive the base 41 forward and generates a corresponding positive torque. The rotational torque sensor detects the change in torque, and the controller immediately controls the servo motor to work, driving the metal mesh roller 42 forward to press against the sole until the preset torque is generated. When the sole rotates, decreasing the linear distance from the side of the sole to the metal mesh roller 42 (i.e., the side of the sole opposite the metal mesh roller 42 rotates from the left and right sides to the front and back sides), the resistance on the metal mesh roller 42 increases. At this time, the electric slide 431 tends to rotate in the reverse direction to drive the base 41 forward and generates a corresponding reverse torque. The rotational torque sensor detects the change in torque, and the controller immediately controls the servo motor to work, driving the metal mesh roller 42 backward to press against the sole until the preset torque is restored. The above description represents the device's operating state and signal transmission between sensors and the controller at a given moment. In actual operation, due to the device's precision and the high efficiency of feedback between components, the device operates extremely smoothly without any obstruction. The controller controls the electric slide 431 to move the metal mesh roller 42 forward or backward to maintain stable torque, thereby ensuring constant pressure from the metal mesh roller 42 on the side of the shoe sole and improving the quality of the rolled texture.

[0049] Furthermore, the workbench 1 is also equipped with an isolation cabinet 11 and an operation panel 12. The controller is located in the isolation cabinet 11 and connected to each component. The isolation cabinet 11 is also equipped with a power supply connected to the thermal radiation heater 44 and the servo motor 432, and an air circuit system connected to the telescopic cylinder 32.

[0050] The working principle of this application is as follows:

[0051] (1) The temperature of the heat radiation heater 44 and the pressure applied by the metal mesh roller 42 are preset, and the heat radiation heater 44 is started according to the preset temperature and the metal mesh roller 42 is preheated. The controller controls the rotary motor 53 to work according to the signals fed back by the first temperature sensor 51 and the second temperature sensor 52, and drives the metal mesh roller 42 to rotate to maintain uniform heating.

[0052] (2) After the preset temperature is reached, the controller controls the power of the thermal radiation heater 44 according to the signals fed back by the first temperature sensor 51 and the second temperature sensor 52 to keep the temperature of the metal mesh roller 42 stable within a range.

[0053] (3) Install the sole. Place the sole to be rolled on the electromagnet 21, and control the telescopic cylinder 32 to move its piston rod 36 downward so that the magnetic sleeve 33 is attracted to the electromagnet 21 by the magnet 37 to hold the sole;

[0054] (4) Start rolling. The rotating seat 2 rotates and drives the shoe sole to rotate. The controller controls the servo motor to work according to the signal fed back by the rotation torque sensor, so that the electric slide 431 drives the metal mesh roller 42 to press the side of the shoe sole with a constant force. At this time, the rotating motor 53 stops, and the metal mesh roller 42 is in a free rolling state. After rotating once, the metal mesh roller 42 rolls around the side of the shoe sole once to complete the texture rolling of the side of the shoe sole.

[0055] (5) Remove the sole. When the electromagnet 21 is de-energized, the piston rod 36 of the telescopic cylinder 32 is retracted. The limiting protrusion 34 at the end of the piston rod 36 cooperates with the limiting inner edge 35 on the magnetic sleeve 33 to lift the magnetic sleeve 33, so that the magnetic sleeve 33 is separated from the electromagnet 21. Then the processed sole is removed.

[0056] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present invention should still fall within the scope of the patent of the present invention.
