[0002] EVA slippers are formed by foaming EVA materials. Compared with traditional PVC slippers, EVA slippers have excellent shock absorption performance, good heat insulation performance, wear resistance, environmental protection, non-toxicity, moisture and odor prevention, good air permeability, and a light foot feeling. Therefore, EVA slippers have gradually replaced PVC slippers.

[0003] However, the EVA material is relatively slippery, resulting in poor anti-slip performance of EVA slippers. Although existing EVA slippers have anti-slip patterns on the bottom, most of the existing anti-slip patterns of EVA slippers are straight or diagonal lines, and the patterns are relatively shallow, which has little improvement on the anti-slip performance of EVA slippers and cannot achieve true anti-slip, with a low safety factor.

[0004] Based on this, it is necessary to propose an anti-slip slipper and its intelligent production process to improve the anti-slip performance of EVA slippers, which has become an important technical problem to be solved urgently. Summary of the Invention

[0013] Based on another object of the present application, the present application also provides an anti-slip slipper.

[0023] Embodiment 1 Refer to Figure 1 As shown, this application proposes an intelligent production process for non-slip slippers. The production process includes the following steps: S1. Periodically extrude a fixed amount of EVA finished product raw material into the molding die through a screw extrusion device; S2. The EVA finished product raw material is molded in the molding die to form a slipper blank. The control center controls the screw extrusion device to extrude a fixed amount of EVA finished product raw material into the molding die. Before extruding the fixed amount of EVA finished product raw material into the molding die, it is also necessary to spray a mold release agent into the cavity of the molding die so that the slipper blank can be smoothly removed from the molding die. A thermocouple and a temperature measuring probe are arranged on the molding die. The control center heats the molding die by controlling the opening and closing of the thermocouple. The control center controls the temperature of the molding die through the temperature measuring probe to make it reach the preset molding temperature. A button-type pressure sensor is also arranged in the molding die. The signal of the button-type pressure sensor is transmitted back to the control center. The control center controls the pressure in the molding die by controlling the screw extrusion device so that the EVA finished product raw material is molded in the molding die under the preset pressure and temperature. After molding, the molding die is cooled, and then the mold can be opened to take out the slipper blank. Through the above steps, the intelligent molding of the slipper blank can be realized, which is beneficial to improving the quality and production efficiency of the slipper blank, thereby improving the quality and production efficiency of the non-slip slipper 1. The control center is preferably a CPU. S3. Trim the slipper blank to obtain a semi-finished slipper; After the slipper blank is molded, it still needs to be trimmed so that its shape and size meet the design requirements. The molding step of the slipper blank mainly includes two parts. One is to trim the shape of the slipper blank through a shoe last to make its shape conform to the design requirements, and the other is to perform cold setting on the slipper blank to make its size conform to the design requirements. Through the above steps, it can be ensured that the shape and size of the semi-finished slipper both meet the design requirements and improve the quality of the finally formed non-slip slipper 1.

[0024] Specifically, the purpose of the above steps is to use a fully automatic EVA injection and one-time molding machine for high-temperature in-mold foaming molding. After the slipper blank is taken out of the mold, it is shaped with a shoe last and aged and sized in an incubator to obtain a compliant EVA semi-finished slipper.

[0025] S4. Clean the semi-finished slippers and improve the surface adhesion of the semi-finished slippers by applying roughening agent to obtain the shoe body. Two sticking grooves 5 are provided on the sole 101 of the shoe body; the cleaning step of the semi-finished slippers is mainly to remove the impurities on the semi-finished slippers to avoid the impurities on the semi-finished slippers affecting the subsequent processing steps. Here, it is preferred to use a 200T cleaning agent to clean the semi-finished slippers. After cleaning the semi-finished slippers, it is necessary to apply roughening agent to improve the surface adhesion of the semi-finished slippers to initially improve the anti-slip performance of the semi-finished slippers. It is preferred to use an EVA795E treatment agent for the roughening agent, and the temperature of the roughening agent is preferably 50 + 2 °C. Through the above steps, the impurities on the surface of the semi-finished slippers can be effectively removed, and the surface adhesion of the semi-finished slippers can be improved by applying roughening agent to initially improve the anti-slip performance of the semi-finished slippers.

[0026] Among them, before cleaning the semi-finished slippers, the semi-finished slippers need to be placed in an irradiator and irradiated with high-temperature UV light to destroy the surface smoothness and grease, and enhance the adhesive force of the glue.

[0027] S5. Stick the anti-slip patch 4 into the corresponding sticking groove 5 of the shoe body to obtain the anti-slip slipper 1. After completing the pre-treatment process of the slippers, the sticking step of the anti-slip patch 4 needs to be carried out. The material of the anti-slip patch 4 is a material with a high friction coefficient, such as TPR rubber or silicone. The high friction coefficient of the anti-slip patch 4 can effectively make up for the problem of insufficient friction coefficient of the EVA material, effectively improve the anti-slip performance of the anti-slip slipper 1, and the bottom of the anti-slip patch 4 and the bottom of the shoe body are both provided with anti-slip patterns 2 with a depth of 2 mm - 3 mm, further ensuring the anti-slip ability of the anti-slip slipper 1.

[0028] Among them, the forming method of the anti-slip patch 4 is: put the refined RB rubber in the mold as required, and obtain the qualified rubber anti-slip patch 4 after high-pressure and high-temperature forming and cooling and shaping.

[0029] Among them, the sticking step specifically includes: brushing glue on the bottom sticking groove 5 of the processed shoe body, putting the anti-slip patch 4 through the glue machine to apply glue, then baking the glue in the oven, fitting, and using a pressing device to increase the bonding strength. Obtain light, comfortable, wear-resistant and anti-slip slippers.

[0030] Among them, the anti-slip slipper 1 also needs to go through inspection, packaging, and boxing procedures before it can be sold to ensure that defective slippers do not flow out. The slippers made through the above steps, under the detection method of referring to GB / T 3903.6 - 2017 ceramic tiles, three-level water, 400N, horizontal mode, have an anti-slip performance of 0.58, far exceeding the required 0.4 of the design requirements. The slippers prepared through the above process not only take into account the excellent shock absorption performance, good heat insulation performance, wear resistance, environmental protection, non-toxicity, moisture and odor prevention, good air permeability, light foot feeling and other advantages of EVA slippers, but also have excellent anti-slip performance.

[0031] Specifically, in this application, a rubber anti-slip patch 4 with a high coefficient of friction is attached to the sole of the anti-slip slipper 1, effectively compensating for the problem of insufficient coefficient of friction of the EVA material and improving the anti-slip performance of the anti-slip slipper. Moreover, anti-slip patterns with a depth of 2 mm - 3 mm are provided at the bottom of the rubber anti-slip patch and the bottom of the shoe body, further ensuring the anti-slip ability of the anti-slip slipper. This application aims to combine the light and comfortable characteristics of the EVA modified material with the wear-resistant and anti-slip characteristics of the RB rubber, taking into account both material anti-slip and structural anti-slip, giving consumers a brand-new experience. Controlling the molding of the slipper blank through an intelligent control center is beneficial to improving the quality and production efficiency of the slipper blank, thereby improving the quality and production efficiency of the anti-slip slipper 1. After the slipper blank is molded, it is trimmed to ensure that the shape and size of the semi-finished slipper meet the design requirements, improving the quality of the finally formed anti-slip slipper 1. The slipper is treated with a cleaning agent and a roughening agent, effectively cleaning the impurities on the surface of the semi-finished slipper and improving the anti-slip performance of the semi-finished slipper. Ensure that the anti-slip performance of the finally formed anti-slip slipper 1 meets the design requirements.

[0032] In some embodiments, the above S5 specifically includes the following steps: S51. Apply an adhesive to the attachment groove 5 of the shoe body; the steps for applying the adhesive are as follows: first, inject a certain amount of adhesive into the attachment groove 5 of the slipper, and then disperse the adhesive through brushing. During the brushing process, try to avoid excessive accumulation of the adhesive on the side of the attachment groove 5. Through the above steps, adhesive overflow can be effectively avoided, and the connection between the anti-slip patch 4 and the shoe body can be ensured to be firm.

[0033] S52. Insert the anti-slip patch 4 into the corresponding attachment groove 5; S53. Use a pressing device to press the anti-slip patch 4 tightly to form the anti-slip slipper 1. There are two attachment grooves 5 on the shoe body, and the shapes of the two attachment grooves 5 are different. During the process of attaching the anti-slip patch 4, the anti-slip patch 4 corresponding to the shape of the attachment groove 5 should be inserted into this attachment groove 5. During the initial fitting process, the position of the anti-slip patch 4 needs to be completely corresponding to the attachment groove 5, and then the anti-slip patch 4 is initially attached to the attachment groove 5. Then, the patch is pressed into the attachment groove 5 through a pressing device to achieve a firm connection between the anti-slip patch 4 and the shoe body. Through the above steps, the connection strength between the anti-slip patch 4 and the shoe body can be effectively improved, ensuring the improvement of the quality of the finally formed anti-slip slipper 1.

[0034] In some embodiments, the above S3 specifically includes the following steps: S31. Trim the shape of the slipper blank through a shoe last; the shoe last is designed and formed based on the foot shape, and the shoe last is the mother body of the shoe. The shoe last not only determines the shape and style of the shoe. The slipper blank is set on the shoe last, and the shape of the slipper blank is trimmed according to the shoe last, thereby ensuring that the shape and style of the slipper meet the design requirements; S32. Place the slipper blank into an incubator and adjust the temperature in the incubator to -15°C to 10°C; S33. Stretch the slipper blank in the incubator so that the size of the slipper blank meets the design requirements to form a semi-finished slipper. The incubator is used to provide a constant-temperature cold environment. The slipper blank is stretched in the cold environment so that the size of the slipper blank meets the design requirements, avoiding the influence of the expansion effect caused by high heat on the size of the final formed anti-slip slipper 1.

[0035] In some embodiments, the forming method of the slipper blank in S2 above is specifically as follows: During the forming process of the slipper blank, the temperature in the forming mold is 170°C to 185°C, and the pressure in the forming mold is 100 MPa to 140 MPa. The EVA finished product raw material is formed under the above temperature and pressure. After heat preservation and pressure holding for 6 minutes, the forming mold is cooled to form a slipper blank. A thermocouple and a temperature measuring probe are provided on the forming mold. The control center heats the forming mold by controlling the opening and closing of the thermocouple. The control center controls the temperature of the forming mold through the temperature measuring probe to make it reach the preset forming temperature. A button-type pressure sensor is also provided in the forming mold. The model of the button-type pressure sensor is transmitted back to the control center. The control center controls the pressure in the forming mold by controlling the screw extrusion equipment so that the EVA finished product raw material is formed in the forming mold under the preset pressure and temperature. After forming, the forming mold is cooled, and then the mold can be opened to take out the slipper blank. A cooling structure is also provided in the forming mold, and the cooling structure is preferably an oil cooling structure.

The sliding table 10, the sliding table 10 is movably arranged at the upper end of the workbench 7; the sliding table 10 is the foundation of structures such as the transverse movement drive 8 and the sleeve plate 11. A chute is arranged on the sliding table 10, and a corresponding slide rail 14 is arranged on the workbench 7. The movement direction of the sliding table 10 is defined by the cooperation of the chute and the slide rail 14, and the stability of the movement of the sliding table 10 is improved. The transverse movement drive 8, the transverse movement drive 8 is arranged at the upper end of the workbench 7, and the transverse movement drive 8 is connected to the sliding table 10; the transverse movement drive 8 is the power source for the movement of the sliding table 10. The transverse movement drive 8 is a hydraulic cylinder. An installation frame 15 is arranged on the transverse movement drive 8, and the transverse movement drive 8 is installed on the workbench 7 through the installation frame 15.

The sleeve plate 11, the sleeve plate 11 is arranged at the upper end of the sliding table 10, and the anti-slip slipper 1 is sleeved on the sleeve plate 11; one end of the sleeve plate 11 is fixed to the sliding table 10, and the other end of the sleeve plate 11 is for the anti-slip slipper 1 to be inserted. The shape and size of the sleeve plate 11 match the sole 101 of the anti-slip slipper 1. The clamping drive 13, the clamping drive 13 is arranged at the upper end of the sliding table 10. The clamping drive 13 includes two hydraulic cylinders, the two hydraulic cylinders are communicated with the hydraulic station, and the actions of the two hydraulic cylinders are controlled through the hydraulic station. The two hydraulic cylinders are arranged on both sides of the sleeve plate 11, and the two hydraulic cylinders are both provided with output ends. Clamping plates 12 adapted to the anti-slip slipper 1 are arranged on the output ends of the two hydraulic cylinders; after the anti-slip slipper 1 is sleeved on the sleeve plate 11, the anti-slip slipper 1 is driven by the transverse movement drive 8 to move towards the pressure roller 9. When the anti-slip slipper 1 completely passes over the pressure roller 9, the pressing of the anti-slip patch 4 can be completed.

[0037] In this embodiment, multiple sliding tables 10 are provided, and the multiple sliding tables 10 are connected to the same transverse movement drive 8, so as to realize pressing the anti-slip patches 4 on multiple anti-slip slippers 1 at one time, which is beneficial to improving the processing efficiency.

[0044] Refer to Figure 2 As shown in the figure, in some embodiments, the non-slip slipper 1 further includes: non-slip patterns 2, and non-slip patterns 2 are provided on both the shoe body and the non-slip patch 4, and the depth of the non-slip patterns 2 is 2 mm - 3 mm. The non-slip patterns 2 are concave-convex structures designed by imitating the bear's paw in the Arctic. The non-slip patterns 2 are deep and dense (about 2 - 3 mm), and can form multi-directional gripping teeth during walking, which is beneficial to enhancing the anti-slip ability of the non-slip slipper 1.

[0045] Among them, the non-slip slipper 1 further includes: drainage grooves 3, and the drainage grooves 3 are embedded between the non-slip patterns 2. The drainage grooves 3 between the non-slip patterns 2 can quickly divert liquids and avoid slipping due to water accumulation.

[0046] Refer to Figure 10 and Figure 11As shown, in some embodiments, the anti-slip slipper further includes: a plurality of connecting grooves 1011 that are spaced apart from each other and disposed on the inner wall surface of the pasting groove 5. The cross-section of the connecting groove 1011 is arc-shaped. The wall surface of the pasting groove 5 is a first inclined surface, and the side surface of the anti-slip patch 4 is a second inclined surface 42 adapted to the first inclined surface. Through the cooperation of the first inclined surface and the second inclined surface 42, it can effectively prevent the anti-slip patch 4 from coming out of the pasting groove 5, and the setting of the first inclined surface and the second inclined surface 42 is beneficial to increasing the contact area between the anti-slip patch 4 and the pasting groove, so that the adhesive can better paste the anti-slip patch 4 into the pasting groove 5. The connecting groove 1011 is an annular arc-shaped groove arranged uniformly along the slope direction of the first inclined surface. A plurality of first connecting protrusions 41 are spaced apart from each other and disposed on the side surface of the anti-slip patch 4. The first connecting protrusions 41 are adapted to the connecting grooves 1011. The first connecting protrusions 41 are annular arc-shaped protrusions arranged uniformly along the slope direction of the second inclined surface 42. At least two second connecting protrusions 43 are disposed near the top end of the anti-slip patch 4. The top end of the anti-slip patch 4 is the end where the anti-slip patch 4 extends into the pasting groove 5. The cross-section of the second connecting protrusion 43 is arc-shaped. The diameter of the second connecting protrusion 43 is smaller than the diameter of the connecting groove 1011. The second connecting protrusions 43 are annular arc-shaped protrusions arranged uniformly along the slope direction of the second inclined surface 42. The total number of the first connecting protrusions 41 and the second connecting protrusions 43 is equal to the number of the connecting grooves 1011. During the pressing process, the pressing roller 9 will first press the first connecting protrusions 41 and the second connecting protrusions 43 into the corresponding connecting grooves 1011 respectively, and then increase the pressure to force the anti-slip patch 4 and the sole 101 to be compressed and deformed, so that the adhesive can flow into the gap between the anti-slip patch and the pasting groove 5. Since both the anti-slip patch 4 and the sole 101 will deform during the compression and deformation process, the gap between the anti-slip patch 4 and the pasting groove 5 will become smaller during the compression and deformation, and at this time, the adhesive will overflow, so that the adhesive can fill the gap between the anti-slip patch 4 and the pasting groove 5, but it may also cause the adhesive at the bottom of the pasting groove 5 to be pressed out of the pasting groove 5. By providing the second connecting protrusions 43 with a diameter smaller than that of the connecting groove 1011, a glue-retaining gap will exist between the connecting groove 1011 and the second connecting protrusions 43. Even during the compression and deformation process, the glue-retaining gap between the connecting groove 1011 and the second connecting protrusions 43 will not be completely closed. At this time, a part of the adhesive at the bottom of the pasting groove 5 is effectively retained in the glue-retaining gap, preventing the adhesive from being pressed out. After the compression and deformation ends, the sole 101 and the anti-slip patch 4 return to their original shapes under the action of their own elastic forces, so that the gap between the top of the anti-slip patch 4 and the bottom of the pasting groove 5 returns to the initial size. At this time, a certain negative pressure suction force will be generated, so as to suck the adhesive in the glue-retaining gap, ensuring that a certain amount of adhesive is retained between the top of the anti-slip patch 4 and the bottom of the pasting groove 5, and ensuring the connection strength between the anti-slip patch 4 and the sole 101.Moreover, the size and shape of the first connecting protrusion 41 are adapted to the connecting groove 1011. During the pressing process, the cooperation between the first connecting protrusion 41 and the connecting groove 1011 can also increase the contact area between the anti-slip patch 4 and the slot 5, so that in addition to filling the gap between the anti-slip patch 4 and the slot 5, the adhesive also needs to fill the gaps between a plurality of first connecting protrusions 41 and the connecting groove 1011 before overflowing from the slot 5, effectively avoiding the occurrence of glue overflow.

[0047] Wherein, a first guiding portion 1012 is further provided between the connecting groove 101 and the sole 101. The setting of the first guiding portion 1012 is beneficial to the demolding of the sole 101 and is also beneficial to the insertion of the first connecting protrusion 41 and the second connecting protrusion 43. A second guiding portion 44 is provided between the first connecting protrusion 41 and the second connecting protrusion 43 and the anti-slip patch 4. The setting of the second guiding portion 44 is beneficial to the insertion of the first connecting protrusion 41 and the second connecting protrusion 43 into the corresponding connecting groove 101.
