DETAILED DESCRIPTION

[0041] The core of the utility model is to provide a PU antistatic insole preparation device to improve the production efficiency of the PU antistatic insole.

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] PU material, or polyurethane, is a polymer material with excellent properties and is widely used in many fields, such as textiles, construction, aviation, shipping, transportation, medicine, electronics, etc. PU anti-static insoles are light in weight, soft in texture, and have excellent flexural resistance. They can provide very good shock absorption and rebound effects, and have anti-static effects, and are very popular among people.

[0044] The PU antistatic insole includes a cloth surface layer, a cork layer and a PU foam layer which are stacked in sequence, wherein the two sides of the heel of the PU foam layer are folded upward to form a support bracket extending from the heel to the arch of the foot, so that the PU antistatic insole has better cushioning and anti-slip effects, and improves the wearing comfort.

[0045] However, in the production process of PU antistatic insoles, it is necessary to spread the PU film bundles flat on the workbench, and then use a cutter to cut out the insoles (semi-finished products) in batches on the PU film. After the cutting is completed, the cutter is withdrawn, and the batch of insoles is still left on the workbench. The insoles need to be manually picked out of the PU film and collected. This insole production method is relatively cumbersome, resulting in low insole production efficiency.

[0046] For this reason, Figure 1 As shown, the embodiment of the utility model discloses a PU antistatic insole preparation device, including a lifting part 1 and a cutting table 4. The PU pad material is cut into insoles by the annular knife 3 of the lifting part 1, and the insoles are lifted into the stacking groove 2 by the lifting plate 42 on the cutting table 4. Compared with the traditional insole production method, the production method is simpler, and there is no need to manually pick out the insoles from the PU film for collection, which saves a lot of manpower and improves the production efficiency of the PU antistatic insoles.

[0047] The following will be combined Figures 1 to 8 The PU antistatic insole preparation device disclosed in the embodiment of the utility model is specifically explained and illustrated.

[0048] Among them, Figure 1As shown, the lifting part 1 is provided with a stacking groove 2 for stacking insoles, and an annular knife 3 corresponding to the stacking groove 2 is provided at the bottom of the lifting part 1, and a supporting ridge 21 for supporting the insole is provided on the inner wall of the stacking groove 2. A knife groove 41 cooperating with the annular knife 3 is provided on the cutting table 4, and a lifting plate 42 is movably provided on the cutting table 4, and the lifting plate 42 is provided corresponding to the stacking groove 2. The lifting part 1 drives the annular knife 3 to move toward the knife groove 41 close to the cutting table 4, so that the annular knife 3 cuts the PU mat material laid on the cutting table 4 into insoles, and the cut insoles are lifted into the stacking groove 2 by the lifting plate 42, and pass over the supporting ridge 21, so that the insole on the lifting plate 42 enters the stacking groove 2 above the supporting ridge 21, and the insole is blocked by the supporting ridge 21 and remains in the stacking groove 2. As the annular knife 3 continues to cut out the insoles, the insoles will be stacked in the stacking groove 2 from bottom to top. When the insoles in the stacking groove 2 are stacked to a certain number of layers, it is only necessary to take out the insoles in the stacking groove 2 at one time. Compared with the traditional insole production method, the production method is simpler and there is no need to manually pick out the insoles from the PU film and collect them, which saves a lot of manpower and improves the production efficiency of PU antistatic insoles.

[0049] In a specific embodiment, if Figure 1 and Figure 3 As shown, the lifting part 1 is located above the cutting table 4, and the lifting part 1 can rise and fall in the vertical direction. In this embodiment, the lifting part 1 can be driven by a hydraulic device to achieve the lifting function, and an electric drive device or a pneumatic drive device can also be used to drive the lifting part 1 to achieve the lifting function, which is not limited in this article. Figure 2 As shown, the cross-sectional shape of the stacking groove 2 is the same as the outer contour shape of the insole, and the cross-sectional size of the stacking groove 2 is larger than the outer contour size of the insole, so that the insole can be stacked in the stacking groove 2. Preferably, a notch 22 extending along the stacking direction of the insole is provided on the side wall of the stacking groove 2, so that the insole can be taken out after the stacking groove 2 is full of insoles. The shape of the annular knife 3 is exactly the same as the shape of the insole, and the knife groove 41 is adapted to the annular knife 3 to ensure that the PU pad material is cut into the shape of the insole. In addition, the annular space formed by the annular knife 3 is aligned and connected with the stacking groove 2 to ensure that the insole formed by cutting the annular knife 3 can be directly lifted into the stacking groove 2 through the lifting plate 42 to be supported on the supporting edge 21.

[0050] Furthermore, if Figure 4 and Figure 7As shown, the support rib 21 is a convex rib-like structure arranged on the inner wall of the stacking groove 2, and the support rib 21 can be a continuous annular arrangement along the inner wall of the stacking groove 2, that is, an annular convex rib-like structure, or can be an intermittent arrangement along the inner wall of the stacking groove 2, that is, an intermittent convex rib-like structure, so as to prevent the insole located above the support rib 21 from sliding out of the stacking groove 2, thereby supporting the insole in the stacking groove 2. Preferably, the inner contour shape of the support rib 21 and the shape of the lifting plate 42 are the same as those of the insole, the inner contour dimension of the support rib 21 is smaller than the outer contour dimension of the insole, and the outer contour dimension of the lifting plate 42 is smaller than the inner contour dimension of the support rib 21. Since the insole has a resettable deformation capability, the insole is located on the lifting plate 42 after cutting, and the lifting plate 42 lifts the insole upward. When the insole passes through the support rib 21, it is deformed due to the force of the lifting plate 42 to pass through the support rib 21 and enter into In the stacking groove 2, the outer contour size of the lifting plate 42 is smaller than the inner contour size of the supporting edge 21, so that the lifting plate 42 can pass directly through the supporting edge 21. Once the insole passes through the supporting edge 21, the insole immediately returns to its original shape. Then, after the lifting plate 42 descends and leaves the stacking groove 2, the insole is supported in the stacking groove 2 by the supporting edge 21. Since the mass of the insole is small, the weight of the insole is not enough to cause it to deform and pass over the supporting edge 21 downward, so that the insole is finally left in the stacking groove 2.

[0051] Furthermore, if Figure 7As shown, when there are multiple insoles stacked in the stacking groove 2 and the number of insoles is large, in order to ensure that each insole can be stably located in the stacking groove 2 and to avoid the insole at the bottom being deformed and sliding off the supporting ridge 21 due to the large number of insoles, preferably, at least two supporting ridges 21 are provided on the inner wall of the stacking groove 2 along the stacking direction of the insoles, so that each insole can be supported in layers by at least two supporting ridges 21, thereby distributing the weight of each insole on the two supporting ridges 21 to ensure that the insole at the bottom layer on each supporting ridge 21 is subjected to less force, effectively avoiding the risk of the insole at the bottom being deformed and sliding off the supporting ridge 21 due to the large number of insoles, thereby enabling more insoles to be stacked in the stacking groove 2, and at the same time, the supporting ridge 21 located above can be used as a backup support. When the supporting ridge 21 located at the bottom is severely worn, the insole can be lifted by the lifting plate 42 to pass over the supporting ridge 21 above to ensure that the insole can still be stably supported in the stacking groove 2. Of course, the number of supporting ridges 21 can be, but not limited to, two, and can also be three, four or more, to further reduce the force on the bottom layer of the insole on each supporting ridge 21, thereby ensuring that each insole can be stably located in the stacking groove 2. Preferably, each supporting ridge 21 is evenly spaced and distributed on the inner wall of the stacking groove 2 along the stacking direction of the insole, ensuring the uniform force on each supporting ridge 21, reducing the wear of the supporting ridge 21, and improving the service life of the PU antistatic insole preparation device, while allowing more insoles to be stacked in the stacking groove 2. It should be noted that in this embodiment, the stacking direction of the insole is the vertical direction of the stacking groove 2.

[0052] Furthermore, if Figure 4 and Figure 6 As shown, the supporting ridge 21 has two surfaces arranged opposite to each other. For the convenience of understanding, the two surfaces of the supporting ridge 21 are defined as a first surface and a second surface. The first surface is the upper surface of the supporting ridge 21, and the first surface is a plane to support the insole. The second surface is the lower surface of the supporting ridge 21, and a guide portion is provided on the second surface of the supporting ridge 21 to facilitate the insole to pass through. The guide portion can be an inclined surface or an arc surface to facilitate the insole to deform from bottom to top so as to pass through the supporting ridge 21 and enter the stacking groove 2.

[0053] Furthermore, if Figure 2 and Figure 7 As shown, the cross-sectional shape of the stacking groove 2 is the same as the outer contour shape of the insole, and the cross-sectional size of the stacking groove 2 is larger than the outer contour size of the insole. At the same time, the supporting edge 21 is inclined toward the notch 22 side of the stacking groove 2, so that the insole can be tilted and stacked on the supporting edge 21 to ensure that the insole is aligned and placed. Figure 7 and Figure 8As shown. Since the space in the stacking groove 2 is larger than the insole, the insole has a certain degree of freedom of movement in the stacking groove 2. At the same time, since the supporting edge 21 is arranged obliquely, the insole is obliquely stacked on the supporting edge 21 in the stacking groove 2. The stacked insole will generate a certain vibration during the rising and falling process of the lifting part 1, so that the downwardly inclined end of the insole is neatly against the inner wall of the stacking groove 2, so that the insole can be neatly stacked obliquely in the stacking groove 2, which solves the problem that when the insole slides upward relative to the stacking groove 2, it is completely in contact with the inner wall of the stacking groove 2 and the friction force is large, resulting in individual insoles being clamped between the inner wall of the stacking groove 2 and the stacked insoles.

[0054] Furthermore, the lifting plate 42 can be controlled by a separate lifting mechanism to perform a lifting action so as to lift the insole on the lifting plate 42 into the stacking groove 2 .

[0055] In a specific embodiment, the PU antistatic insole preparation device further includes a transmission assembly. When the lifting part 1 drives the annular knife 3 to enter the knife groove 41, the lifting part 1 drives the lifting plate 42 to lift toward the stacking groove 2 through the transmission assembly, so as to lift the insole on the lifting plate 42 into the stacking groove 2. Specifically, Figure 4 and Figure 6As shown, the transmission assembly includes a first sliding part 5, a second sliding part 6, a sliding rod 7 and an abutting rod 11. The first sliding part 5 can be vertically slidably arranged on the side of the cutting table 4 away from the lifting part 1, that is, the bottom of the cutting table 4, and an inclined first guide groove 51 is provided on the first sliding part 5. The second sliding part 6 is fixedly connected to the lifting plate 42, and an inclined second guide groove 61 is provided on the second sliding part 6, and the inclined direction of the second guide groove 61 is opposite to the inclined direction of the first guide groove 51. The sliding rod 7 can be horizontally slidably arranged on the side of the cutting table 4 away from the lifting part 1, that is, the bottom of the cutting table 4, and the horizontal sliding direction is the straight line direction between the first guide groove 51 and the second guide groove 61, and the sliding rod 7 is slidably connected to the first guide groove 51 and the second guide groove 61 respectively, that is, two sliding posts are provided on the sliding rod 7, one of which is slidably arranged in the first guide groove 51, and the other sliding post is slidably arranged in the second guide groove 61. The abutment rod 11 is fixedly connected to the lifting part 1, and the abutment rod 11 is vertically arranged. At the same time, a through hole 43 is arranged at a position corresponding to the abutment rod 11 on the cutting table 4. The inner contour size of the through hole 43 is larger than the outer contour size of the abutment rod 11, and the first sliding part 5 can slide vertically along the through hole 43. The lifting part 1 drives the abutment rod 11 to move in the direction close to the cutting table 4 until the abutment rod 11 abuts against the first sliding part 5, so that the first sliding part 5 slides in the direction away from the cutting table 4, that is, the first sliding part 5 slides vertically downward along the through hole 43. Preferably, the abutment rod 11 is provided with an abutment end 111 of a pointed cone structure, and the first sliding part 5 is provided with a tapered groove 52 matched with the abutment end 111.

[0056] In this embodiment, if Figure 4 and Figure 6 As shown, the descending stroke of the lifting part 1 is divided into a continuous first stroke and a second stroke. Figure 4 As shown, the first stroke is that the lifting part 1 drives the annular knife 3 and the abutting rod 11 to descend a first preset distance, the abutting rod 11 first pierces the PU film and enters the through hole 43 on the cutting table 4, and then the annular knife 3 cuts the PU film laid on the cutting table 4 into insoles. Since the abutting rod 11 first pierces the PU film and enters the through hole 43, the abutting rod 11 has a positioning effect on the PU film, so that when the annular knife 3 cuts the PU film, the PU film will not shift, ensuring that the size of the cut insole is more accurate. Figure 6As shown, the second stroke is that the lifting part 1 drives the annular knife 3 and the abutting rod 11 to descend together by a second preset distance, and the second preset distance is greater than the first preset distance. At this time, the annular knife 3 enters the knife groove 41 of the cutting table 4, and the abutting rod 11 abuts against the first sliding part 5, pressing the first sliding part 5 downward. By designing the abutting end 111 of the abutting rod 11 as a pointed cone structure, it is convenient for the abutting rod 11 to pierce the PU film. At the same time, in order to increase the contact area between the abutting end 111 of the abutting rod 11 and the first sliding part 5 and ensure the stability of the abutting rod 11 pushing the first sliding part 5 to slide, a conical groove 52 is set at the top of the first sliding part 5, so that the abutting end 111 of the abutting rod 11 enters the conical groove 52, and the abutting end 111 of the abutting rod 11 forms a surface contact with the conical groove 52, so that the abutting end 111 of the abutting rod 11 can be sharp, and the force transmission between the abutting rod 11 and the first sliding part 5 is more stable. In the process of the contact rod 11 pressing the first sliding part 5 downward, the first sliding part 5 squeezes the sliding rod 7 through the first guide groove 51, so that the sliding rod 7 slides horizontally relative to the cutting table 4, and the sliding rod 7 slides and squeezes the second sliding part 6 through the second guide groove 61, so that the second sliding part 6 moves vertically upward, and at the same time, the second sliding part 6 drives the lifting plate 42 to lift upward, and the lifting plate 42 lifts the insole on it over the supporting edge 21 and places it in the stacking groove 2. Subsequently, the lifting part 1 rises and resets, and the lifting plate 42 descends and resets under the action of gravity. The mass of the lifting plate 42 is much greater than the mass of the first sliding part 5. During the process of the lifting plate 42 descending and resetting, the second sliding part 6, the sliding rod 7 and the first sliding part 5 are reset through the reverse transmission between the second sliding part 6, the sliding rod 7 and the first sliding part 5. The next round of the above-mentioned insole preparation process is carried out, so that the insole is stacked in the stacking groove 2 from bottom to top.

[0057] The embodiment of the utility model also discloses a method for preparing a PU antistatic insole. The insole preparation device used in the PU antistatic insole preparation method is the PU antistatic insole preparation device disclosed in the above embodiment, so it has all the technical effects of the above PU antistatic insole preparation device, which will not be described in detail herein. The PU antistatic insole preparation method includes the steps of laying a PU mat material, cutting the PU mat material, and lifting the insole.

[0058] The following is a specific explanation and description of a method for preparing a PU antistatic insole disclosed in an embodiment of the utility model.

[0059] Lay the PU mat material on the cutting table 4 below the lifting part 1.

[0060] To cut the PU mat material, the lifting part 1 descends a first preset distance, so that the annular knife 3 cuts the PU mat material on the cutting table 4 into insoles.

[0061] The insole is lifted, and the lifting part 1 continues to descend, that is, the lifting part 1 descends a second preset distance, so that the annular knife 3 enters the knife groove 41. At the same time, the lifting part 1 drives the lifting plate 42 to lift upward, lift the insole into the stacking groove 2 and support it on the supporting edge 21. At this time, the lifting part 1 rises and resets, and the lifting plate 42 descends and resets under the action of gravity. The insole remains in the stacking groove 2 under the obstruction of the supporting edge 21, thereby completing the preparation of the insole. Then, repeat the above steps, and the insole can be stacked from bottom to top into the stacking groove 2, without the need to manually pick out the insole from the PU film for collection, saving a lot of manpower and improving the production efficiency of PU antistatic insoles.
