Description

Technical Field

[0001] The invention belongs to the field of sole processing equipment, in particular to a sole surface fine texture forming equipment and a rolling method thereof. Background Art

[0002] ETPU is a type of TPU material formed by supercritical foaming. Because its appearance resembles popcorn, the sports shoe midsole made of ETPU is called popcorn midsole. It has the advantages of excellent resilience, extremely low compression permanent deformation, good wearing experience, and environmentally friendly and efficient processing.

[0003] After the existing popcorn soles are produced, they will show irregular granular dark patterns on the surface. Similar textures bring aesthetic fatigue to consumers, and the granular dark patterns also have a certain adverse effect on the appearance design of the shoe body. Therefore, there is a practical need in the industry to eliminate the granular dark patterns on the surface of popcorn soles. In order to eliminate these dark patterns, the existing solution is to open a dense texture on the inner wall of the mold, and cover the granular dark patterns on the surface of the sole by forming a dense concave-convex texture until they cannot be identified by the naked eye. The mold corresponding to the dense texture needs to be manufactured by high-precision metal 3D printing. Compared with traditional machined metal molds, its cost is high, so this solution is difficult to be accepted by the market. How to design a low-cost new solution to achieve the coverage of the granular dark patterns on the popcorn soles has become the problem to be solved in this case. Summary of the invention

[0011] Preferably, the hot rolling device also includes a driving mechanism, which includes an electric slide and a servo motor. The electric slide is arranged on the workbench, and the base is arranged on the electric slide. The servo motor is connected to the electric slide to drive the electric slide to drive the base to move back and forth to drive the metal mesh roller to roll the sole.

[0012] Preferably, the control device also includes a rotational torque sensor arranged between the servo motor and the electric slide, the servo motor is connected to the controller, and the servo motor is controlled to operate according to a signal fed back by the rotational torque sensor, so that 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.

[0014] Preferably, 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.

[0015] Preferably, the base includes a slider, an extension section, a balancing section and a counterweight, the slider is movably arranged on the electric slide; the extension section is extended outwardly from the upper edge of the slider close to the clamping station, and the metal mesh roller and the thermal radiation heater are arranged on the extension section; the balancing section is formed on the slider in a direction opposite to the extension section; the counterweight is arranged on the balancing section to balance the base.

[0016] Preferably, an isolation cabinet and an operation panel are also provided on the workbench, the controller is arranged in the isolation cabinet and connected to various components, and a power supply connected to the thermal radiation heater and the servo motor, and an air circuit system connected to the telescopic cylinder are also provided in the isolation cabinet.

[0017] Preferably, the metal mesh roller comprises a soft roller core connected to the rotating motor and a metal mesh sleeve sleeved on the outside of the soft roller core, wherein the top of the metal mesh sleeve is fixed on the top surface of the soft roller core and the bottom freely hangs on the outside of the soft roller core.

[0018] A method for hot rolling of sole texture, comprising any one of the above-mentioned sole surface fine texture forming equipment, the method comprising:

[0019] (1) Preheating the metal mesh roller, starting the thermal radiation heater, and controlling the rotation motor according to the feedback signals from the first temperature sensor and the second temperature sensor to drive the metal mesh roller to rotate to ensure uniform heating;

[0020] (2) maintaining the temperature, according to the feedback signals from 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 on the clamping station;

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

[0023] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects: after the metal mesh roller is heated by the thermal radiation heater, the side of the foamed sole is hot-rolled to form a fine texture, covering the dark texture formed by the popcorn particles, without the need to make an expensive dense mold, and at the same time, by arranging a first temperature sensor and a second temperature sensor on the front and rear sides of the metal mesh roller, while maintaining the temperature of the metal mesh roller stable, the controller can control the rotation of the metal mesh roller according to the temperature difference fed back by the two sensors to maintain uniform heating, thereby avoiding inconsistent texture forming due to uneven temperature when rolling the texture;

[0024] The electric slide cooperates with the servo motor to accurately control the movement of the metal mesh roller, improving the texture quality of the roller pressing on the side of the sole;

[0025] The rotary torque sensor is used to control the pressure of the metal mesh roller against the sole and keep it stable. When the metal mesh roller moves in the direction close to the sole and contacts the sole, the resistance of the electric slide increases, and the torque of the internal lead screw changes. The controller can control the servo motor to drive the electric slide to stop at the position corresponding to the preset torque according to the preset value 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 keep the torque stable, 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 the top of the sole through the telescopic cylinder, adsorbs with the electromagnet and clamps the sole between the two. At this time, the telescopic cylinder does not directly contact the sole, and the sole is only subjected to the downward suction force of the magnetic sleeve. The magnetic sleeve can rotate around the piston rod. Compared with directly pressing the sole through the cylinder, it can effectively avoid the friction caused by the pressing causing the sole to slip off the rotating seat when the rotating seat rotates. When the piston rod is retracted, the limiting protrusion can also be driven upward by the limiting inner edge to separate the magnetic sleeve and the sole.

[0027] The inner diameter of the inner edge of the limit is larger than the diameter of the piston rod and smaller than the outer diameter of the limit protrusion, so that when the telescopic cylinder is installed, it is not necessary to fit the rotating seat with extremely high assembly accuracy, so that a larger coaxiality deviation is allowed 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 metal mesh roller needs to be set to extend outward to the outside of the electric slide, so it is necessary to install a counterweight to balance the slide to avoid the movement of the slide being affected by the center of gravity shift;

[0029] The metal mesh sleeve has a certain elasticity and hangs on the outside of the soft roller core. When the soft roller core is pressed on the side of the sole, the dense texture of the metal mesh sleeve is rolled onto the sole, which is not easy to deform the sole and further improves the quality of the product.

DETAILED DESCRIPTION

[0038] The present invention is further described below through specific implementation modes.

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

[0040] The rotating seat 2 is rotatably arranged on the workbench 1 . An electromagnet 21 made of a metal material is arranged on the rotating seat 2 , and the sole is placed on the electromagnet 21 .

[0041] The fixing device 3 is arranged on the workbench 1 and is opposite to the rotating seat 2, and a clamping station for clamping the sole is formed between the two. The fixing device 3 includes a bracket 31, a telescopic cylinder 32, a magnetic sleeve 33, a limit convex block 34 and a limit inner edge 35. The bracket 31 is arranged on the workbench 1 and is located above the rotating seat 2; the telescopic cylinder 32 is arranged on the bracket 31 and is 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 downward with it to approach the rotating seat 2; the limiting protrusion 34 is extended outward from the end of the piston rod 36; the limiting inner edge 35 is extended inward 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 adapted to the rotating seat with extremely high assembly precision when installed, so that a larger coaxiality deviation is allowed between the two, reducing the assembly requirements and assembly difficulty. The magnetic sleeve 33 is moved downward to the top of the sole through the telescopic cylinder 32 and absorbs and clamps the sole on the electromagnet 21 of the rotating seat 2. At this time, the telescopic cylinder 32 is not in direct contact with the sole, and the sole is only subjected to the suction force of the magnetic sleeve 33 being attracted downward by the electromagnet 21, and the magnetic sleeve 33 can rotate around the piston rod 36. Compared with directly pressing the sole through the cylinder, it can effectively avoid the friction force generated by the pressing causing the sole to slip off the rotating seat 2 when the rotating seat 2 rotates. When the piston rod 36 is retracted, it can also drive the limiting protrusion 34 to move upward through the limiting inner edge 35 to separate the magnetic sleeve 33 and the sole.

[0042] Specifically, a magnet 37 is provided at the bottom of the magnetic sleeve 33, and the magnetic sleeve 33 can clamp the sole on the electromagnet 21 and rotate with the rotating seat 2, and the diameters of the electromagnet 21 and the magnetic sleeve 33 are smaller than the narrowest part of the sole to avoid the sole being blocked by the electromagnet 21 or the magnetic sleeve 33 so that the metal mesh roller 42 cannot roll over this position.

[0043] The hot rolling device 4 includes a base 41, a metal mesh roller 42, a driving mechanism 43 and a heat radiation heater 44. The base 41 is arranged on the workbench 1 to move back and forth in a direction away from or close to the clamping station; the metal mesh roller 42 is arranged on the base 41 and can be opposite to the clamping station, and its rotation axis is perpendicular to the workbench 1; the driving mechanism 43 is arranged on the workbench 1 to drive the base 41 to move back and forth to drive; the heat radiation heater 44 is arranged on the base 41 and opposite to the metal mesh roller 42 to continuously heat the metal mesh roller 42. After the metal mesh roller 42 is heated by the heat radiation heater 44, the side of the foamed sole is hot-rolled to form a new texture, without the need to make an expensive dense mold.

[0044] Specifically, the base 41 includes a slider 411, an extension section 412, a balancing section 413 and a counterweight 414. The slider 411 is movably set on the electric slide 431; the extension section 412 is extended and formed from the upper edge of the slider 411 close to the clamping station, and the metal mesh roller 42 and the thermal radiation heater 44 are arranged on the extension section 412; the balancing section 413 is formed on the slider 411 along the opposite direction of the extension section 412; the counterweight 414 is arranged on the balancing section 413 to balance the base 41. Since the metal mesh roller 42 needs to be close to the clamping station for rolling, the setting position of the metal mesh roller 42 needs to extend outward to the outside of the electric slide 431. Therefore, it is necessary to install the counterweight 414 to balance the slider 411 to avoid the movement of the slider 411 being affected by the shift of the center of gravity.

[0045] Furthermore, the driving mechanism 43 includes an electric slide 431 and a servo motor 432 . The electric slide is disposed on the workbench 1 , and the base 41 is disposed on the electric slide 431 . The servo motor 432 is connected to the electric slide 431 to drive the electric slide 431 to drive the base 41 to move 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 arranged on both sides of the metal mesh roller 42; the rotary motor 53 is arranged on the base 41 to drive the metal mesh roller 42 to rotate so that it is heated evenly; the controller controls the rotation of the rotary motor 53 and controls the operation of the thermal radiation heater 44 according to the signals fed back by 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 are not further described here. By arranging the first temperature sensor 51 and the second temperature sensor 52 on the front and rear sides of the metal mesh roller 42, while keeping the temperature of the metal mesh roller 42 stable, the metal mesh controller can control the rotation of the metal mesh roller 42 according to the temperature difference fed back by the two sensors to keep the heating evenly, so as to avoid inconsistent texture forming due to uneven temperature when rolling the texture. When rolling the texture, the rotating motor 53 is in a stopped state, and the metal mesh roller 42 is in a freely rotatable state. At this time, the metal mesh roller 42 contacts the outer side of the sole and rolls on the outer side of the sole under the action of friction, thereby completing the texture rolling.

[0047] Specifically, the metal mesh roller 42 includes a soft roller core 421 connected to the rotating 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 on the top surface of the soft roller core 421 and the bottom is freely hanging 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 is pressed on the side of the sole, the dense texture of the metal mesh sleeve 422 is rolled onto the sole, which makes it difficult for the sole to be deformed, thereby further improving the quality of the product.

[0048] Furthermore, the control device 5 also includes a rotation torque sensor disposed between the servo motor 432 and the electric slide 431. The servo motor 432 is connected to the controller. The servo motor 432 is controlled to work according to the signal fed back by the rotation torque sensor. When the sole rotates with the rotating seat 2, the metal mesh roller 42 is controlled to always press against the side of the sole with the same force. The rotation torque sensor is used to control the pressure of the metal mesh roller 42 against the sole and keep it stable. When 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 is converted into the torque generated when the corresponding electric slide 431 moves. When the sole rotates to increase the straight-line distance from the side of the sole to the metal mesh roller 42 (that is, the side opposite to the metal mesh roller 42 rotates from the front and rear ends to the left and right sides), the resistance to the metal mesh roller 42 decreases. At this time, the electric slide 431 has a tendency to rotate in the positive direction to drive the base 41 to move forward and generate a corresponding positive torque. The rotational torque sensor detects the change in torque, and the controller immediately controls the servo electric operation to drive the metal mesh roller 42 to move forward and press against the sole until a preset torque is generated; when the sole rotates to reduce the straight-line distance from the side of the sole to the metal mesh roller 42 (that is, the side opposite to the metal mesh roller 42 rotates from the left and right sides to the front and rear sides), the resistance to the metal mesh roller 42 increases. At this time, the electric slide 431 has a tendency to rotate in the reverse direction to drive the base 41 to move forward and generate a corresponding reverse torque. The rotational torque sensor detects the change in torque, and the controller immediately controls the servo electric operation to drive the metal mesh roller 42 to move backward and press against the sole until the preset torque is restored. The above description is the working state of the device and the signal transmission between the sensor and the controller in an instant. In the actual process, due to the precision of the device and the high efficiency of the feedback between the components, the device operates very smoothly without any blocking. The controller controls the electric slide 431 to drive the metal mesh roller 42 forward or backward to maintain a stable torque, so as to achieve a constant pressure of the metal mesh roller 42 on the side of the sole, thereby improving the quality of the rolled texture.

[0049] Furthermore, an isolation cabinet 11 and an operation panel 12 are also provided on the workbench 1. The controller is arranged in the isolation cabinet 11 and connected to various components. The isolation cabinet 11 is also provided with a power supply connected to the thermal radiation heater 44 and the servo motor 432 and an air path system connected to the telescopic cylinder 32.

[0050] The working principle of this application is:

[0051] (1) The temperature of the thermal radiation heater 44 and the pressure applied by the metal mesh roller 42 are preset, and the thermal radiation heater 44 is started and the metal mesh roller 42 is preheated according to the preset temperature. The controller controls the rotation 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 reaching the preset temperature, the controller controls the power of the thermal radiation heater 44 according to the feedback signals from 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) Installing the sole. The sole to be rolled is placed on the electromagnet 21, and the telescopic cylinder 32 is controlled to move its piston rod 36 downward until the magnetic sleeve 33 is adsorbed on the electromagnet 21 through the magnet 37 to clamp the sole;

[0054] (4) Start rolling. The rotating seat 2 rotates and drives the sole to rotate. The controller controls the servo motor according to the signal fed back by the rotating torque sensor, so that the electric slide 431 drives the metal mesh roller 42 to always press on the side of the 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 one circle, the metal mesh roller 42 rolls around the side of the sole for one circle, completing the texture rolling forming of the side of the sole;

[0055] (5) Remove the sole. The electromagnet 21 is powered off, and the piston rod 36 of the telescopic cylinder 32 is controlled to retract. The magnetic sleeve 33 is lifted by the limit protrusion 34 set at the end of the piston rod 36 and the limit inner edge 35 on the magnetic sleeve 33, so that the magnetic sleeve 33 is separated from the electromagnet 21, and then the processed sole is removed.

[0056] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the scope of the patent application of the present invention and the contents of the specification should still fall within the scope covered by the patent of the present invention.
