Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shoe sole processing, in particular to an automatic processing equipment for shoe sole anti-skid lines. BACKGROUND

[0002] In the preparation process of the molten rubber sole, the core process is to inject the molten rubber material into the mold recess with a preset pattern, and after cooling and solidification, a shoe sole blank with anti-skid structure is formed. However, this forming process has a significant technical problem: after the molten rubber is injected into the mold, due to the influence of injection pressure, mold clamping gap and other factors, the top and periphery of the shoe sole blank are prone to form burrs and irregular concave-convex defects due to material overflow. Such defects will directly affect the appearance flatness of the shoe sole and the subsequent assembly accuracy, so it must be removed through subsequent finishing process.

[0003] For the above overflow defects, the existing technology generally uses mechanical scraping to process, that is, through the use of blades, scrapers and other tools to manually or semi-automatically scrape off the burrs and irregular concave-convex parts on the top and periphery of the shoe sole, so as to realize the flattening processing of the shoe sole surface. The core idea of this processing method is to directly remove the excess overflow material by means of the cutting action of the tool, which is simple in principle and does not require complex equipment, and is widely used in small and medium batch shoe sole production scenes.

[0004] However, the existing mechanical scraping finishing scheme has defects that are difficult to avoid in actual application: due to the high elasticity and flexibility of the rubber material itself, when scraping the irregular concave-convex parts on the top of the shoe sole, the resistance force generated by the contact between the tool and the shoe sole surface is easy to cause the shoe sole to curl and deform; the curling of the shoe sole will cause the irregular concave-convex parts at the bottom to fail to maintain a flat processing posture, which not only increases the operation difficulty of the bottom scraping, but also easily causes incomplete scraping, over-scraping and uneven thickness of the shoe sole.

[0005] Therefore, we propose an automatic processing equipment for shoe sole anti-skid lines to improve the above shortcomings. SUMMARY

[0006] The present application provides an automatic processing equipment for shoe sole anti-skid lines, which solves the problem of easy curling of the shoe sole at the irregular concave-convex parts on the top of the product shoe sole.

[0007] To achieve the above purpose, the automatic processing equipment for shoe sole anti-skid lines comprises a concave mold and a convex mold arranged at intervals, and a limiting mold is arranged between the two; The limiting mold, the concave mold and the convex mold are all provided with a contraction pipe, one end of the top of the concave mold is slidably connected with a separation plate, one end of the separation plate close to the concave mold is respectively provided with a tool and a pressing roller, the tool is fixedly connected with the separation plate, and the pressing roller is rotatably connected with the separation plate; The separating plate is used to open the concave mold and the convex mold after the sole pattern is formed. The limiting mold prevents the molten sole material from overflowing to the surrounding area to prevent the sole from forming burrs. After the concave mold and the convex mold are opened, the separating plate sliding along the top of the concave mold can drive the cutter to flatten the irregular concave and convex parts at the top of the sole. Along the direction of movement of the cutter, the pressure roller is located upstream of the cutter and is used to press the upstream sole of the flattened area to prevent the sole from rolling up.

[0008] In the above technical solution, the shrink tube includes multiple sleeves distributed along a height gradient, each sleeve is slidably connected to each other, and the upper sleeve can be retracted into the lower sleeve.

[0009] Furthermore, springs are fitted around the periphery of the plurality of said sleeves; When the sleeve is located between the die cavity and the limiting die, the top of the uppermost sleeve is fixedly connected to the bottom of the limiting die, and the bottom of the lowermost sleeve is fixedly connected to the top of the die cavity. When the sleeve is located between the punch and the limiting die, the top of the uppermost sleeve is fixedly connected to the bottom of the punch, and the bottom of the lowermost sleeve is fixedly connected to the top of the limiting die.

[0010] Furthermore, the top of the concave mold has a pair of symmetrically arranged shoe sole tread grooves, and the convex mold has anti-overflow grooves at corresponding positions above the two shoe sole tread grooves. The shape of the anti-overflow grooves is adapted to the surrounding contour of the shoe sole tread grooves to prevent the molten rubber material injected into the shoe sole tread grooves from overflowing to the surroundings. The bottom of the convex mold has pressing protrusions at corresponding positions above the two shoe sole tread grooves. The pressing protrusions cooperate with the shoe sole tread grooves to press the molten rubber material into the shoe sole and press out the anti-slip treads on the shoe sole.

[0011] With this design, the separation plate has multiple pressing channels opened in the vertical direction, and each pressing roller is located in the pressing channel, and the diameter of the pressing roller is greater than or equal to the depth of the pressing channel.

[0012] Based on the above, a drive rod is provided at the axis of the plurality of pressing rollers. The drive rod is used to drive the pressing rollers to rotate around the axis in the pressing channel. The drive rod is fixedly connected to the plurality of pressing rollers.

[0013] Both ends of the drive rod that are far apart are coaxially equipped with gears, and a rack is fixedly installed above the gears on the bottom of the limiting mold. When the separating plate slides along the surface of the limiting mold, the rack is used to drive the gears to rotate.

[0014] In this technical solution, the rack drives the gears to rotate, which in turn rotates the pressing rollers. This ensures that the sole does not curl due to its inherent flexibility during the process of the blades flattening the irregular bumps and depressions at the top of the sole, thus ensuring that all irregular bumps and depressions at the top of the sole are flattened.

[0015] In addition, the blade and the separating plate are provided with grooves on their respective sides, and the two grooves form a heating chamber. The heating chamber is provided with a heating element, which includes a guide rod. The two ends of the guide rod that are far apart are provided with limit caps. A heating wire is sleeved between the two limit caps. The blade is made of a high thermal conductivity metal.

[0016] As can be seen from the above scheme, when the heating wire is energized, the heat is transferred to the limiting cap. As the guide rail slides along the guide groove, the high-temperature blade flattens the irregular bumps and depressions on the top of the shoe sole.

[0017] Based on the above description, the beneficial effects of the present invention compared with the prior art are as follows: After the sole cools and forms anti-slip texture, the separation plate slides along the upper surface of the die by inserting the guide rail into the guide groove. The separation plate lifts the limiting mold that was originally close to the die. Under the action of the spring restoring force, the die and the limiting mold, and the die and the punch separate from each other to achieve mold opening.

[0018] After the sole is formed in the groove of the sole, the guide rail is inserted into the guide groove and the separation plate is pushed. Since the teeth of the rack mesh with the gear, the rack drives the gear to rotate, which in turn rotates each pressing roller. This ensures that the sole will not curl due to its own flexibility during the process of the blade flattening the irregular concave and convex parts at the top of the sole, and ensures that all the irregular concave and convex parts at the top of the sole are flattened.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In existing technologies, due to the high elasticity and flexibility of rubber materials, when removing irregular bumps and depressions at the top of the sole, the resistance generated by the contact between the blade and the sole surface can easily cause the sole to curl and deform. The curling of the sole will cause the irregular bumps and depressions on the bottom to lose their flat, unprocessed position, which not only increases the difficulty of bottom scraping, but also easily leads to problems such as incomplete scraping or over-scraping, resulting in uneven sole thickness.

[0023] Please see Figure 1 and Figure 2 In order to solve the problems existing in the prior art, the purpose of the present invention is to provide an automated processing equipment for anti-slip patterns on shoe soles. The processing equipment includes a concave mold 100 and a convex mold 110 spaced apart, with a limiting mold 120 between them. Shrink tubes 140 are provided between the limiting mold 120 and the concave mold 100 and the convex mold 110. A separation plate 200 is slidably connected to one end of the top of the concave mold 100. A cutter 210 and a pressing roller 300 are respectively provided at one end of the separation plate 200 near the concave mold 100. The cutter 210 is fixedly connected to the separation plate 200, and the pressing roller 300 is rotatably connected to the separation plate 200. The separation plate 200 is used to open the mold of the concave mold 100 and the convex mold 110 after the sole pattern is formed. The limiting mold 120 prevents the sole from forming burrs by limiting the overflow of molten sole material to the surrounding area. After the concave mold 100 and the convex mold 110 are opened, the separation plate 200, which slides along the top of the concave mold 100, can drive the cutter 210 to flatten the irregular concave and convex parts on the top of the sole. Along the direction of movement of the cutter 210, the pressing roller 300 is located upstream of the cutter 210. The pressing roller 300 is used to press the upstream side of the shoe sole at the flattened area to prevent the shoe sole from rolling up.

[0024] During implementation, the concave mold 100 and the convex mold 110 are first closed, and molten rubber material for making the shoe sole is injected between them. During this process, the height of the shrink tube 140 is shortened, so that the top of the concave mold 100 is close to the bottom of the limiting mold 120 and the bottom of the convex mold 110 is close to the top of the limiting mold 120. The limiting mold 120 prevents the molten rubber material in the cavity from overflowing to the surroundings, thereby preventing burrs from appearing around the shoe sole after it is formed. After the sole cools and solidifies, forming a stable anti-slip pattern, the separating plate 200 is inserted into the top of the concave mold 100 and slids. The separating plate 200 separates the concave mold 100 from the convex mold 110. Then, the shrink tube 140 returns to its length, lifting both of them up. During the process of the cutter 210 flattening the top of the sole, the pressure roller 300 rolls along the top of the sole to press it down. At the same time, due to the rolling contact method between the pressure roller 300 and the top of the sole, compared with sliding contact, it ensures the pressing force on the sole while reducing the friction between the pressure roller 300 and the contact point of the sole, preventing the middle part of the sole from bulging upwards.

[0025] During the mold closing stage of the concave mold 100 and the convex mold 110, a stable clamping force is required to prevent melt overflow. After the molten EVA, TPU, and other raw materials injected into the cavity form anti-slip textures with raised / grooved structures through pressure holding and cooling, it is necessary to avoid deformation or damage to the textures due to impact loads during mold opening. This is especially true for fine anti-slip textures, such as mesh patterns and wave patterns, where traditional processes struggle to balance mold closing stability and mold opening smoothness. To address these issues, the industry mainstream adopts a fully hydraulically driven mold opening and closing method: during mold closing, a controllable high-pressure clamping force is provided by a bidirectional hydraulic cylinder to counteract the molten expansion force and ensure cavity sealing; during mold opening, a reversing valve switches the oil circuit to reverse the hydraulic cylinder and achieve mold separation.

[0026] However, using a fully hydraulically driven mold opening and closing method cannot completely eliminate mold opening impact, because the switching of the reversing valve will cause sudden changes in oil circuit pressure, which will still cause the mold to pop open instantly, resulting in chipping and wear of fine textures, and affecting the anti-slip performance of the shoe sole.

[0027] For a better understanding of the above content, please refer to [link / reference]. Figure 3As shown, the shrink tube 140 includes multiple sleeves distributed along a height gradient, each sleeve being slidably connected to each other, and the upper sleeve being able to retract into the lower sleeve.

[0028] Furthermore, springs 141 are fitted around the periphery of multiple sleeves; When the sleeve is located between the die 100 and the limiting die 120, the top of the uppermost sleeve is fixedly connected to the bottom of the limiting die 120, and the bottom of the lowermost sleeve is fixedly connected to the top of the die 100. When the sleeve is located between the punch 110 and the limiting die 120, the top of the uppermost sleeve is fixedly connected to the bottom of the punch 110, and the bottom of the lowermost sleeve is fixedly connected to the top of the limiting die 120.

[0029] Furthermore, the top of the concave mold 100 is provided with a pair of symmetrically arranged sole tread grooves 101, and the convex mold 110 is provided with anti-overflow grooves 121 at corresponding positions above the two sole tread grooves 101. The shape of the anti-overflow grooves 121 is adapted to the contour of the sole tread grooves 101 to prevent the molten rubber material injected into the sole tread grooves 101 from overflowing to the surroundings. The bottom of the convex mold 110 is provided with pressing protrusions 111 at corresponding positions above the two sole tread grooves 101. The pressing protrusions 111 cooperate with the sole tread grooves 101 to press the molten rubber material into the sole and press out the anti-slip tread pattern on the sole.

[0030] Next, the driving method for the mold closing of the die 100, the limiting mold 120, and the punch 110 is disclosed: a gantry frame 130 is provided above the punch 110, the bottom of the gantry frame 130 is fixedly connected to the die 100, and a hydraulic rod 131 is provided on the upper part of the gantry frame 130. The hydraulic rod 131 includes a cylinder body and a piston end. The cylinder body is fixedly connected to the gantry frame 130, and the piston end is fixedly connected to the top of the punch 110.

[0031] The following describes the driving method for opening the die 100, the limiting die 120, and the punch 110: The top of the die 100 is provided with several guide grooves 102, and the bottom of the separation plate 200 is fixedly connected with the same number of guide rails 201 as the guide grooves 102. The shape of the guide rails 201 is adapted to the internal contour of the guide grooves 102.

[0032] Compared with full-mode hydraulic drive and pure spring mold closing methods, the hydraulic drive mold closing + insertion of the separation plate 200 mold opening method adopted in this application has the following advantages: The mold closing stage is driven by hydraulic rod 131. The mold closing pressure can be precisely set according to the shoe size and the fluidity of the raw materials, such as the melt characteristics of EVA and TPU, such as 5-20MPa. This ensures that the concave mold 100, the limiting mold 120, and the convex mold 110 fit tightly together, completely offsetting the expansion force of the melt during injection molding, and avoiding overflow and flash problems in the anti-slip texture cavity of the shoe sole.

[0033] For shoe sole molds with fine anti-slip textures, a stable holding pressure is required during the injection cooling stage to prevent the texture from shrinking and deforming. The hydraulic rod 131 can achieve closed-loop control of the holding pressure, maintaining the stability of the mold in the closed state; while pure spring mold closing cannot provide continuous and stable holding pressure, which can easily lead to the collapse of the texture.

[0034] It should be noted that after the sole cools and forms anti-slip texture, the guide rail 201 is inserted into the guide groove 102 to make the separation plate 200 slide along the upper surface of the die 100. The separation plate 200 lifts the limiting mold 120 that was originally close to the die 100. Then, under the action of the restoring force of the spring 141, the die 100 and the limiting mold 120, and the die 100 and the punch 110 separate from each other to achieve mold opening.

[0035] like Figures 4-6 As shown, the separation plate 200 has multiple pressing channels 301 opened in the vertical direction, and each pressing roller 300 is located in the pressing channel 301, and the diameter of the pressing roller 300 is greater than or equal to the depth of the pressing channel 301.

[0036] Based on the above, a drive rod 310 is provided at the axis of the multiple pressing rollers 300. The drive rod 310 is used to drive the pressing rollers 300 to rotate around the axis in the pressing channel 301. The drive rod 310 is fixedly connected to the multiple pressing rollers 300.

[0037] exist Figure 7 In the middle, gears 320 are coaxially arranged at both ends of the drive rod 310 that are far apart. A rack 330 is fixedly arranged above the gears 320 at the bottom of the limiting mold 120. When the separation plate 200 slides along the surface of the limiting mold 120, the rack 330 is used to drive the gears 320 to rotate.

[0038] In other words, after the sole is formed in the groove 101, the guide rail 201 is inserted into the guide groove 102 and the separation plate 200 is pushed. Since the teeth of the rack 330 mesh with the gear 320, the rack 330 drives the gear 320 to rotate, causing each pressing roller 300 to rotate. This ensures that the sole will not curl due to the flexibility of the sole itself during the process of the cutter 210 flattening the irregular bumps and depressions at the top of the sole, and ensures that all the irregular bumps and depressions at the top of the sole are flattened.

[0039] Finally, combine Figure 8The principle of the cutting tool 210 for smoothing the irregular concave and convex parts at the top of the shoe sole is as follows: The cutting tool 210 and the separating plate 200 are both provided with grooves on the side that are close to each other. The two grooves form a heating chamber. The heating chamber is provided with a heating element 220. The heating element 220 includes a guide rod 222. The two ends of the guide rod 222 that are far apart are provided with a limiting cap 221. An electric heating wire 223 is sleeved between the two limiting caps 221. The cutting tool 210 is made of a high thermal conductivity metal.

[0040] When the heating wire 223 is energized, the heat is transferred to the limiting cap 221. As the guide rail 201 slides along the guide groove 102, the high-temperature blade 210 flattens the irregular bumps and depressions on the top of the shoe sole.

[0041] The working principle of automated processing equipment will be explained in more detail below: First, the concave mold 100 and the convex mold 110 are closed, and molten rubber material for making the shoe sole is injected between them. During this process, the upper sleeve retracts into the lower sleeve, so that the top of the concave mold 100 is in close contact with the bottom of the limiting mold 120 and the bottom of the convex mold 110 is in close contact with the top of the limiting mold 120. The limiting mold 120 prevents the molten rubber material in the shoe sole groove 101 from overflowing to the surroundings, thereby preventing rough edges from appearing around the shoe sole after it is formed.

[0042] Next, after the sole cools and forms anti-slip texture, the guide rail 201 is inserted into the guide groove 102 to make the separation plate 200 slide along the upper surface of the die 100. The separation plate 200 lifts the limiting mold 120 that was originally close to the die 100. Then, under the action of the restoring force of the spring 141, the die 100 and the limiting mold 120, and the die 100 and the punch 110 separate from each other to achieve mold opening.

[0043] Then, the heating wire 223 is energized and heated, and the heat is transferred to the limiting cap 221. As the guide rail 201 slides along the guide groove 102, the high-temperature blade 210 flattens the irregular bumps and depressions on the top of the shoe sole.

[0044] After the sole is formed in the groove 101, the guide rail 201 is inserted into the guide groove 102 and the separation plate 200 is pushed. Since the teeth of the rack 330 mesh with the gear 320, the rack 330 drives the gear 320 to rotate, causing each pressing roller 300 to rotate. This ensures that the sole will not curl due to the flexibility of the sole itself during the process of the cutter 210 flattening the irregular bumps and depressions at the top of the sole, and ensures that all the irregular bumps and depressions at the top of the sole are flattened.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
