Description

Technical Field

[0001] This invention relates to the field of insole production technology, and more specifically, to a PU antistatic insole preparation device and preparation method. Background Technology

[0002] PU material, or polyurethane, is a high-performance polymer material widely used in various fields, such as textiles, construction, aviation, shipbuilding, transportation, medicine, and electronics. PU antistatic insoles are lightweight, soft, and have excellent flexural properties, providing very good shock absorption and rebound effects, and also have antistatic properties, making them very popular.

[0003] In the existing technology, the production process of PU antistatic insoles requires laying the PU film flat on the workbench and then cutting the insoles (semi-finished products) in batches using a cutter. After the cutting is completed, the cutter is removed, but the batch of insoles is still left on the workbench. The insoles need to be manually removed from the PU film and collected. This insole production method is relatively cumbersome, resulting in low production efficiency.

[0004] Therefore, how to improve the production efficiency of PU antistatic insoles has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a PU antistatic insole manufacturing apparatus to improve the production efficiency of PU antistatic insoles.

[0006] Another object of the present invention is to provide a method for preparing PU antistatic insoles using the above-described PU antistatic insole preparation apparatus.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A PU antistatic insole manufacturing apparatus, comprising:

[0009] The lifting part is provided with a stacking groove for stacking insoles. The bottom of the lifting part is provided with a ring blade corresponding to the stacking groove. The inner wall of the stacking groove is provided with a support ridge for supporting the insoles.

[0010] The cutting table has a groove for cooperating with the annular blade, and a lifting plate is movably provided on the cutting table, the lifting plate being correspondingly provided with the stacking groove;

[0011] The lifting unit is used to drive the annular blade to move towards the blade groove near the cutting table to cut the PU pad material to form the insole. The lifting plate is used to lift the insole into the stacking groove and support it on the support ridge.

[0012] Optionally, the above-mentioned PU antistatic insole manufacturing device further includes a transmission assembly, wherein the lifting part drives the lifting plate to lift through the transmission assembly;

[0013] When the lifting unit drives the annular cutter into the cutter groove, the lifting unit drives the lifting plate to rise towards the stacking groove side through the transmission assembly.

[0014] Optionally, in the above-mentioned PU antistatic insole manufacturing apparatus, the transmission component includes:

[0015] The first sliding part is vertically slidably disposed on the side of the cutting table away from the lifting part, and the first sliding part is provided with an inclined first guide groove;

[0016] The second sliding part is fixedly connected to the lifting plate, and the second sliding part is provided with an inclined second guide groove, the inclination direction of the second guide groove being opposite to the inclination direction of the first guide groove.

[0017] A sliding rod is slidably disposed on the side of the cutting table away from the lifting part, and the sliding rod is slidably connected to the first guide groove and the second guide groove respectively;

[0018] The abutment rod is fixedly connected to the lifting part. The lifting part drives the abutment rod to move closer to the cutting table until the abutment rod abuts against the first sliding part, so that the first sliding part slides away from the cutting table.

[0019] Optionally, in the above-mentioned PU antistatic insole preparation device, the abutting rod is provided with an abutting end with a pointed cone structure, and the first sliding part is provided with a conical groove that cooperates with the abutting end.

[0020] Optionally, in the above-mentioned PU antistatic insole manufacturing apparatus, the support rib is arranged in a ring along the inner wall of the stacking groove, and the inner contour shape of the support rib is the same as the outer contour shape of the insole, and the inner contour dimension of the support rib is smaller than the outer contour dimension of the insole.

[0021] Optionally, in the above-mentioned PU antistatic insole manufacturing apparatus, the shape of the lifting plate is the same as the shape of the supporting ridge, and the outer contour dimension of the lifting plate is smaller than the inner contour dimension of the supporting ridge.

[0022] Optionally, in the above-mentioned PU antistatic insole preparation apparatus, the cross-sectional shape of the stacking groove is the same as the outer contour shape of the insole, and the cross-sectional dimension of the stacking groove is larger than the outer contour dimension of the insole.

[0023] Optionally, in the above-mentioned PU antistatic insole manufacturing apparatus, the supporting rib has a first surface and a second surface disposed opposite to each other, the first surface being used to support the insole, and the second surface being provided with a guide portion to facilitate the passage of the insole.

[0024] Optionally, in the above-mentioned PU antistatic insole preparation device, a notch extending along the stacking direction of the insole is provided on the side wall of the stacking groove, and the supporting ridge is inclined toward the notch side of the stacking groove.

[0025] Optionally, in the above-mentioned PU antistatic insole preparation device, a plurality of insoles are stacked in the stacking groove, and at least two support ridges are provided on the inner wall of the stacking groove along the stacking direction of the insoles.

[0026] A method for preparing PU antistatic insoles, using the PU antistatic insole preparation apparatus as described in any of the preceding claims, includes the following steps:

[0027] Lay out the PU pad material on the cutting table;

[0028] The PU padding material is cut, and the lifting part is lowered by a first preset distance so that the ring blade cuts the PU padding material to form an insole;

[0029] The insole is raised, the lifting part descends a second preset distance, the annular blade enters the blade groove, and the lifting plate lifts the insole into the stacking groove and supports it on the support ridge. The second preset distance is greater than the first preset distance.

[0030] The PU antistatic insole manufacturing apparatus provided by this invention uses a lifting unit to drive a ring cutter to move towards a slot near the cutting table. This allows the ring cutter to cut the PU padding material laid flat on the cutting table into insoles. A lifting plate then lifts the cut insoles into a stacking slot, passing over a support ridge, so that the insoles on the lifting plate enter the stacking slot above the support ridge. The insoles remain in the stacking slot due to the obstruction of the support ridge. As the ring cutter continues to cut insoles, they are stacked sequentially from bottom to top into the stacking slot. Once a certain number of layers have been stacked, the insoles can be removed from the stacking slot all at once. As can be seen from the above example, the PU antistatic insole manufacturing apparatus provided by this invention is simpler to produce than traditional insole manufacturing methods. It eliminates the need for manual removal of insoles from the PU film, saving significant manpower and improving the production efficiency of PU antistatic insoles.

Detailed Implementation

[0042] The core of this invention is to provide a PU antistatic insole manufacturing device to improve the production efficiency of PU antistatic insoles.

[0043] Another core aspect of this invention is to provide a method for preparing PU antistatic insoles using the aforementioned PU antistatic insole preparation apparatus.

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] PU material, or polyurethane, is a high-performance polymer material widely used in various fields, such as textiles, construction, aviation, shipbuilding, transportation, medicine, and electronics. PU antistatic insoles are lightweight, soft, and have excellent flexural properties, providing very good shock absorption and rebound effects, and also have antistatic properties, making them very popular.

[0046] The PU antistatic insole consists of a fabric surface layer, a cork layer, and a PU foam layer stacked in sequence. The PU foam layer has two sides folded up at the heel to form a support extending from the heel to the arch of the foot, which gives the PU antistatic insole good cushioning and anti-slip effect, improving wearing comfort.

[0047] However, in the production process of PU antistatic insoles, the PU film needs to be laid flat on the workbench, and then the insoles (semi-finished products) are cut in batches from the PU film using a knife. After the cutting is completed, the knife is removed, and the batch of insoles are left on the workbench. The insoles need to be manually removed from the PU film and collected. This insole production method is relatively cumbersome, resulting in low production efficiency.

[0048] Therefore, such as Figure 1As shown in the figure, this invention discloses a PU antistatic insole manufacturing device, including a lifting unit 1 and a cutting table 4. The PU padding material is cut into insoles by the ring blade 3 of the lifting unit 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 for manual removal and collection of insoles from the PU film, saving a lot of manpower and improving the production efficiency of PU antistatic insoles.

[0049] The following will combine Figures 1 to 8 The PU antistatic insole preparation apparatus disclosed in the embodiments of the present invention will be explained and described in detail.

[0050] Among them, such as Figure 1 As shown, the lifting unit 1 is provided with a stacking groove 2 for stacking insoles. A ring-shaped blade 3 corresponding to the stacking groove 2 is provided at the bottom of the lifting unit 1, and a support ridge 21 for supporting the insoles is provided on the inner wall of the stacking groove 2. A cutting table 4 has a cutting groove 41 that cooperates with the ring-shaped blade 3, and a lifting plate 42 is movably provided on the cutting table 4, corresponding to the stacking groove 2. The lifting unit 1 drives the ring-shaped blade 3 to move towards the cutting groove 41 near the cutting table 4, so that the ring-shaped blade 3 cuts the PU padding material laid flat on the cutting table 4 into insoles. The lifting plate 42 lifts the cut insoles into the stacking groove 2, passing over the support ridge 21, so that the insoles on the lifting plate 42 enter the stacking groove 2 above the support ridge 21. The insoles remain in the stacking groove 2 due to the obstruction of the support ridge 21. As the ring blade 3 continues to cut out the insoles, the insoles will be stacked from bottom to top into the stacking groove 2. When the insoles in the stacking groove 2 are stacked to a certain number of layers, the insoles in the stacking groove 2 can be taken out at once. Compared with the traditional insole production method, the production method is simpler. There is no need for manual removal of the insoles from the PU film for collection, which saves a lot of manpower and improves the production efficiency of PU antistatic insoles.

[0051] In one specific embodiment, such as Figure 1 and Figure 3 As shown, the lifting unit 1 is located above the cutting table 4, and the lifting unit 1 can rise and fall vertically. In this embodiment, the lifting unit 1 can be driven by a hydraulic device to achieve the lifting function, or it can be driven by an electric drive device or a pneumatic drive device to achieve the lifting function. This is not limited here. Figure 2As 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 dimension of the stacking groove 2 is larger than the outer contour dimension 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 removed after the stacking groove 2 is full. The shape of the ring blade 3 is exactly the same as the shape of the insole, and the blade groove 41 is adapted to the ring blade 3 to ensure that the PU pad material is cut into the shape of the insole. Furthermore, the annular space formed by the ring blade 3 is aligned and connected with the stacking groove 2 to ensure that the insole formed by the ring blade 3 can be directly lifted into the stacking groove 2 by the lifting plate 42 to be supported on the support ridge 21.

[0052] Furthermore, such as Figure 4 and Figure 7 As shown, the support ridge 21 is a convex ridge structure set on the inner wall of the stacking groove 2. The support ridge 21 can be a continuous annular structure along the inner wall of the stacking groove 2, i.e., an annular convex ridge structure, or it can be intermittently set along the inner wall of the stacking groove 2, i.e., an intermittent convex ridge structure, to prevent the insole located above the support ridge 21 from sliding down into the stacking groove 2, thereby providing support for the insole within the stacking groove 2. Preferably, the inner contour shape of the support ridge 21 and the shape of the lifting plate 42 are the same as the insole. The inner contour dimension of the support ridge 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 ridge 21. Because the insole has a repositionable deformation capability, after the insole is cut, it is positioned on the lifting plate 42. The lifting plate 42 lifts the insole upwards. When the insole passes the support ridge 21, it deforms due to the force of the lifting plate 42 to pass through the support ridge 21 and enter the stacking groove 2. Inside the stacking groove 2, the outer contour of the lifting plate 42 is smaller than the inner contour of the support ridge 21, allowing the lifting plate 42 to pass directly through the support ridge 21. Once the insole passes through the support ridge 21, it immediately returns to its original shape. Subsequently, after the lifting plate 42 descends and leaves the stacking groove 2, the insole is supported by the support ridge 21 within the stacking groove 2. Due to the small mass of the insole, its own weight is insufficient to deform it and allow it to move downwards past the support ridge 21, thus leaving the insole ultimately inside the stacking groove 2.

[0053] Furthermore, such as Figure 7As shown, when there are multiple insoles stacked in the stacking groove 2, and the number of insoles is relatively large, in order to ensure that each insole can be stably located in the stacking groove 2 and to prevent the insole at the bottom from deforming and slipping off the support ridge 21 due to the large number of insoles, preferably, at least two support ridges 21 are provided on the inner wall of the stacking groove 2 along the stacking direction of the insoles, so that each insole is supported in layers by at least two support ridges 21, thereby distributing the weight of each insole on the two support ridges 21, so as to ensure that the bottom insole on each support ridge 21 is subjected to less force, effectively avoiding the risk of the bottom insole deforming and slipping off the support ridge 21 due to the large number of insoles, thereby allowing more insoles to be stacked in the stacking groove 2. At the same time, the support ridge 21 located at the top can be used as a backup support. When the support ridge 21 located at the bottom is severely worn, the insole can be lifted by the lifting plate 42 to pass over the support ridge 21 above, so as to ensure that the insole can still be stably supported in the stacking groove 2. Of course, the number of support ridges 21 can be, but is not limited to, two, three, four, or more, to further reduce the force on the bottom insole on each support ridge 21, thereby ensuring that each insole can be stably positioned within the stacking groove 2. Preferably, the support ridges 21 are evenly distributed along the stacking direction of the insoles on the inner wall of the stacking groove 2, ensuring uniform force on each support ridge 21, reducing wear on the support ridges 21, improving the service life of the PU antistatic insole preparation device, and allowing more insoles to be stacked in the stacking groove 2. It should be noted that, in this embodiment, the stacking direction of the insoles is the vertical direction of the stacking groove 2.

[0054] Furthermore, such as Figure 4 and Figure 6 As shown, the support rib 21 has two opposing surfaces. For ease of understanding, the two surfaces of the support rib 21 are defined as the first surface and the second surface, respectively. The first surface is the upper surface of the support rib 21 and is flat to support the insole. The second surface is the lower surface of the support rib 21, and a guide portion is provided on the second surface of the support rib 21 to facilitate the passage of the insole. The guide portion can be a sloped surface or an arc surface to facilitate the deformation of the insole from bottom to top, so as to pass through the support rib 21 and enter the stacking groove 2.

[0055] Furthermore, such as 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 dimension of the stacking groove 2 is larger than the outer contour dimension of the insole. Simultaneously, the supporting rib 21 is inclined towards the notch 22 of the stacking groove 2, allowing the insole to be stacked at an angle on the supporting rib 21, ensuring that the insole is placed aligned. Figure 7 and Figure 8As shown. Because the space inside the stacking groove 2 is larger than that of the insole, the insole has a certain degree of freedom of movement within the stacking groove 2. At the same time, due to the inclined setting of the support rib 21, the insole is stacked at an angle on the support rib 21 inside 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 downward inclined end of the insole neatly rests against the inner wall of the stacking groove 2. This allows the insole to be neatly stacked at an angle inside the stacking groove 2, solving the problem that when the insole slides upward relative to the stacking groove 2, it comes into complete contact with the inner wall of the stacking groove 2 and the friction is large, which would cause some insoles to be stuck between the inner wall of the stacking groove 2 and the stacked insoles.

[0056] Furthermore, the lifting plate 42 can be controlled by a separate lifting mechanism to lift the insole on the lifting plate 42 into the stacking groove 2.

[0057] In one specific embodiment, the PU antistatic insole manufacturing apparatus further includes a transmission assembly. When the lifting unit 1 drives the annular blade 3 into the blade groove 41, the lifting unit 1 drives the lifting plate 42 to rise towards the stacking groove 2 via the transmission assembly, thereby lifting the insole on the lifting plate 42 into the stacking groove 2. Specifically, as... 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 abutment rod 11. The first sliding part 5 is vertically slidable on the side of the cutting table 4 away from the lifting part 1, i.e., the bottom of the cutting table 4, and has an inclined first guide groove 51. The second sliding part 6 is fixedly connected to the lifting plate 42, and has an inclined second guide groove 61, the inclination direction of which is opposite to that of the first guide groove 51. The sliding rod 7 is horizontally slidable on the side of the cutting table 4 away from the lifting part 1, i.e., the bottom of the cutting table 4. The horizontal sliding direction is the straight line between the first guide groove 51 and the second guide groove 61, and the sliding rod 7 is slidably connected to both the first guide groove 51 and the second guide groove 61. Specifically, the sliding rod 7 has two sliding pillars, one of which is slidably disposed within the first guide groove 51, and the other within the second guide groove 61. The abutment rod 11 is fixedly connected to the lifting part 1 and is vertically arranged. A through hole 43 is provided on the cutting table 4 at a position corresponding to the abutment rod 11. The inner contour dimension of the through hole 43 is larger than the outer contour dimension 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 closer to the cutting table 4 until the abutment rod 11 abuts against the first sliding part 5, causing the first sliding part 5 to slide away from the cutting table 4, i.e., the first sliding part 5 slides vertically downward along the through hole 43. Preferably, the abutment rod 11 is provided with a pointed conical abutment end 111, and the first sliding part 5 is provided with a conical groove 52 that mates with the abutment end 111.

[0058] In this embodiment, as Figure 4 and Figure 6 As shown, the descent of the lifting unit 1 is divided into a continuous first stroke and a second stroke. Wherein, as... Figure 4 As shown, in the first stroke, the lifting unit 1 drives the ring blade 3 and the abutment rod 11 to descend a first preset distance together. The abutment rod 11 first pierces the PU film and enters the through hole 43 on the cutting table 4. Then, the ring blade 3 cuts the PU film laid flat on the cutting table 4 into insoles. Because the abutment rod 11 pierces the PU film first and enters the through hole 43, the abutment rod 11 has a positioning effect on the PU film, so that the PU film will not shift when the ring blade 3 cuts the PU film, ensuring that the cut insoles are more accurate in size. Figure 6As shown, in the second stroke, the lifting part 1 drives the ring blade 3 and the abutment rod 11 to descend a second preset distance, which is greater than the first preset distance. At this time, the ring blade 3 enters the blade groove 41 of the cutting table 4, and the abutment rod 11 abuts against the first sliding part 5, pressing the first sliding part 5 downward. By designing the abutment end 111 of the abutment rod 11 as a pointed cone structure, it is easier for the abutment rod 11 to puncture the PU film. At the same time, in order to increase the contact area between the abutment end 111 of the abutment rod 11 and the first sliding part 5 and ensure the stability of the abutment rod 11 pushing the first sliding part 5 to slide, a conical groove 52 is provided at the top of the first sliding part 5, so that the pointed cone abutment end 111 of the abutment rod 11 enters the conical groove 52, and a surface contact is formed between the pointed cone abutment end 111 of the abutment rod 11 and the conical groove 52. This ensures that the abutment end 111 of the abutment rod 11 is sharp, while making the force transmission between the abutment rod 11 and the first sliding part 5 more stable. During the downward pressing of the abutment rod 11 against the first sliding part 5, the first sliding part 5 presses against the sliding rod 7 through the first guide groove 51, causing the sliding rod 7 to slide horizontally relative to the cutting table 4. The sliding rod 7 then slides and presses against the second sliding part 6 through the second guide groove 61, causing the second sliding part 6 to move vertically upward. At the same time, the second sliding part 6 drives the lifting plate 42 to rise upward, lifting the insole on it over the support ridge 21 and placing 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 descent and reset process of the lifting plate 42, the reverse transmission between the second sliding part 6, the sliding rod 7, and the first sliding part 5 causes the second sliding part 6, the sliding rod 7, and the first sliding part 5 to reset themselves. The next round of the above insole preparation process is then carried out, so that the insoles are stacked in the stacking groove 2 from bottom to top.

[0059] This invention also discloses a method for preparing PU antistatic insoles. The insole preparation device used in this method is the same as the PU antistatic insole preparation device disclosed in the above embodiments, and therefore possesses all the technical effects of the aforementioned PU antistatic insole preparation device, which will not be repeated here. The method includes the steps of laying PU padding material, cutting the PU padding material, and lifting the insole.

[0060] The following will provide a detailed explanation and description of a method for preparing a PU antistatic insole according to an embodiment of the present invention.

[0061] Lay PU padding material on the cutting table 4 below the lifting unit 1.

[0062] When cutting PU padding material, the lifting part 1 descends a first preset distance, so that the ring blade 3 cuts the PU padding material on the cutting table 4 into insoles.

[0063] The insole is lifted, and the lifting unit 1 continues to descend, that is, the lifting unit 1 descends a second preset distance, so that the annular blade 3 enters the blade groove 41. At the same time, the lifting unit 1 drives the lifting plate 42 to rise, lifting the insole into the stacking groove 2 and supporting it on the support ridge 21. At this time, the lifting unit 1 rises to reset, and the lifting plate 42 descends to reset under the action of gravity. The insole remains in the stacking groove 2 due to the obstruction of the support ridge 21, thus completing the preparation of the insole. Then, the above steps are repeated, and the insoles can be stacked into the stacking groove 2 from bottom to top. There is no need to manually remove the insoles from the PU film for collection, saving a lot of manpower and improving the production efficiency of PU antistatic insoles.
