Description

Technical Field

[0001] This invention relates to the field of shoe manufacturing equipment technology, specifically to an EVA foam shoe sole trimming device. Background Technology

[0002] During the production of EVA foam soles, excess material along the parting line must be trimmed to ensure dimensional accuracy, appearance quality, and assembly compatibility. EVA foam soles are produced through injection molding, and flash and excess material inevitably occur at the parting line. This excess material forms irregular protrusions and burrs, resulting in uneven sole edges. Trimming precisely removes this excess material, ensuring a neat and uniform sole edge. Currently, sole trimming machines are primarily used for trimming along the parting line. These machines mainly consist of a cutter drive module and a material support module. The cutter drive module integrates the moving cutter, cutter bar, and drive mechanism, responsible for the reciprocating vibration trimming action of the cutter. The material support module mainly includes a conical disc, which supports and feeds the sole to be trimmed, working in conjunction with the moving cutter above to complete precise trimming, while also positioning and stabilizing the material.

[0003] However, existing EVA foam sole trimming devices require operators to hold the EVA foam sole and press the insole against the conical disc. At the same time, the position of the sole needs to be manually adjusted and the edge to be trimmed needs to be aligned with the cutter. This makes it difficult to limit and guide the sole during trimming, causing the sole to easily shift and loosen during the trimming process, affecting the efficiency and quality of trimming.

[0029] The technical solutions of 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.

[0030] Please see Figures 1-10This invention provides an EVA foam shoe sole trimming device, including a device body. The device body includes a cutter head drive module and a material support module mounted on the machine body. The cutter head drive module includes a cutter head mounting seat 101 and a moving cutter module 102. The material support module includes a base 103, a conical disc 104 and a telescopic transmission shaft 105. The base 103 is also provided with a power and transmission component for driving the telescopic transmission shaft 105 and the conical disc 104 to rotate. These are all well-known technologies in this field and will not be described in detail here. The device body also includes a limiting and guiding mechanism for limiting and guiding the EVA foam shoe sole during trimming.

[0031] The limiting and guiding mechanism includes a mounting block 1201 connected to the cutter head mounting base 101, a guide wheel 1203 connected to the mounting block 1201, and a first rotating shaft 1202 connecting the guide wheel 1203 and the mounting block 1201. The guide wheel 1203 is a V-shaped guide wheel. The limiting and guiding mechanism also includes a moving plate 1204, two pressing rollers 1206 connected to the moving plate 1204, and a second rotating shaft 1205 connecting the pressing rollers 1206 and the moving plate 1204. The limiting and guiding mechanism also includes a moving mechanism connecting the mounting block 1201 and the moving plate 1204. The guide wheel 1203 is positioned close to the moving cutter module 102 to ensure that when the mold parting line 1103 abuts against the guide wheel 1203, the moving cutter module 102 can fit against the trimming position. During trimming, the EVA foam shoe sole is placed between the guide wheel 1203 and the pressing rollers 1206. Meanwhile, the mold-fitting line 1103 is located within the guide wheel 1203. Then, the moving mechanism drives the pressure roller 1206 to move closer to the guide wheel 1203, so that the pressure roller 1206 abuts against the outsole 1102, and the guide wheel 1203 and the moving blade module 102 abut against the mold-fitting line 1103. This flattens the excess material on the mold-fitting line 1103 and makes the moving blade module 102 fit against the trimming position. Then, the conical disc 104 supports and feeds the sole, and the moving blade module 102 performs the trimming operation. During trimming, the guide wheel 1203 always abuts against and rolls against the mold-fitting line 1103, eliminating the need for the operator to hold the EVA foam sole for trimming, making it more convenient and faster. It also limits and guides the EVA foam sole, preventing it from shifting or loosening, thus improving the efficiency and quality of trimming.

[0032] The moving mechanism includes multiple first sleeves 201, multiple first rods 202 connected between the mounting block 1201 and the first sleeves 201, and a pushing assembly for moving the moving plate 1204. The first sleeves 201 are sleeved on the side walls of the first rods 202. The pushing assembly pushes the moving plate 1204 to move. At the same time, the first rods 202 can slide and guide within the first sleeves 201, making the movement of the moving plate 1204 and the pressure roller 1206 more stable and reliable.

[0033] The pushing assembly includes a liquid storage tank 301 connected to the cutter head mounting base 101, a metal plate 304 sliding within the liquid storage tank 301, and a lifting assembly for driving the metal plate 304 to move up and down. The pushing assembly also includes a fixed pipe 302 communicating with the liquid storage tank 301 and a guide rod 303 connecting the fixed pipe 302 and the moving plate 1204. The guide rod 303 is inserted into the fixed pipe 302. The liquid storage tank 301 is filled with hydraulic oil. The lifting assembly drives the metal plate 304 to move up and down within the liquid storage tank 301. Under the action of hydraulic pressure, the guide rod 303 can slide within the fixed pipe 302. The moving plate 1204 drives the pressure roller 1206 to move closer to or away from the guide roller 1203, thereby facilitating the movement of the pressure roller 1206.

[0034] The lifting assembly includes a fixed frame 401 connected to the liquid storage tank 301, a telescopic sleeve 402 connecting the fixed frame 401 and the metal plate 304, and an adsorption assembly disposed between the fixed frame 401 and the metal plate 304. The adsorption assembly includes an electromagnet 404 connected to the fixed frame 401 and an iron block 403 connected to the top of the metal plate 304. The iron block 403 and the electromagnet 404 are arranged opposite to each other. When the electromagnet 404 is energized, it can attract the iron block 403, causing the metal plate 304 to move upward. When the electromagnet 404 is de-energized, the metal plate 304 can move downward along the reservoir 301 under the action of gravity and squeeze the hydraulic oil, thus facilitating the movement of the metal plate 304. Furthermore, under the action of the metal plate 304, the squeezing pressure between the pressure roller 1206 and the outsole 1102, as well as the squeezing pressure between the guide wheel 1203 and the moving knife module 102 and the mold closing line 1103, can be kept constant, allowing the pressure roller 1206 to adapt to the shape of the shoe sole for self-adjustment, making it more convenient and faster.

[0035] The main body of the device also includes a pushing mechanism for moving the conical disc 104; the pushing mechanism includes an annular plate 703 connected to the conical disc 104, an annular cover 701 sleeved on the side wall of the annular plate 703, and a connecting plate 702 connecting the annular cover 701 and the conical disc 104. A sliding groove slider assembly is provided between the annular plate 703 and the annular cover 701 to guide and limit the movement of the annular plate 703; the pushing mechanism also includes a first connecting pipe 704 connecting the annular cover 701 and the fixed pipe 302. When trimming the edge, under the action of hydraulic pressure, the annular plate 703 can move away from the annular cover 701, driving the conical disc 104 to move synchronously and abut against the edge of the insole 1101. Furthermore, when the depth of the insole 1101 changes, under the gravity of the metal plate 304, the conical disc 104 can also be adaptively adjusted and always abut against the edge of the insole 1101, ensuring the support and feeding effect of the EVA foam sole.

[0036] The main body of the device also includes a grinding mechanism for grinding the trimmed edges; the grinding mechanism includes a U-shaped frame 502, a first mounting bracket 501 connected to the cutter head mounting base 101, and a moving component connecting the U-shaped frame 502 and the first mounting bracket 501. The mounting block 1201 is connected to the first mounting bracket 501 via a first support 1207. To ensure that the guide wheel 1203 is positioned close to the moving blade module 102, the grinding mechanism can also be positioned behind the guide wheel 1203; the grinding mechanism also includes a rotating cylinder 505 and a driving component for rotating the rotating cylinder 505; the rotating cylinder 505 includes a U-shaped frame 502, a first mounting bracket 501 connected to the cutter head mounting base 101, and a moving component connecting the U-shaped frame 502 and the first mounting bracket 501. The rotating tube 503 is rotatably connected to the rotating cylinder 505 and is set through the U-shaped frame 502. The grinding mechanism also includes multiple grinding blocks 504 connected to the rotating cylinder 505 and an absorption component for absorbing the grinding debris. When trimming, the U-shaped frame 502 and the rotating cylinder 505 are moved by the moving component, and the grinding blocks 504 abut against the trimmed mold line 1103. The rotating cylinder 505 is driven to rotate by the driving component, so that the grinding blocks 504 can perform grinding operation on the trimmed mold line 1103, thereby improving the quality of trimming.

[0037] The movable component includes a plurality of second sleeves 601 connected to the first mounting bracket 501 and a plurality of second sleeve rods 602 connected between the second sleeves 601 and the U-shaped bracket 502; the second sleeve rods 602 are inserted into the second sleeves 601; the movable component also includes a second connecting pipe 603 connecting the first connecting pipe 704 and the second sleeves 601, so as to ensure that the grinding block 504 abuts against the trimmed mold line 1103 and ensures constant pressure.

[0038] The drive assembly includes a gear ring 901 connected to the rotating tube 503, a gear 904 meshing with the gear ring 901, and a motor 903 connected to the gear 904. The drive assembly also includes a second mounting bracket 902 connected between the motor 903 and the U-shaped frame 502. When the motor 903 is started, the rotation of the motor 903 drives the rotation of the gear 904, which in turn drives the rotating tube 503 to rotate through the gear ring 901, thereby driving the rotating cylinder 505 to rotate.

[0039] The absorption assembly includes a fan 804, a fixing plate 803 connecting the fan 804 and the first mounting bracket 501, and a third connecting pipe 805 connecting the fan 804 and the rotating tube 503. The fan 804 is connected to external dust removal equipment via a pipe, which can be a dust collection box or a dust collection bag. The third connecting pipe 805 is inserted into the rotating tube 503. The absorption assembly also includes multiple first suction holes 801 communicating with the rotating tube 505 and multiple brushes 802 connected to the side wall of the rotating tube 505. When the rotating cylinder 505 rotates, it drives the brush 802 to rotate, thereby cleaning the debris from the grinding mold line 1103. At the same time, the fan 804 is started to perform a ventilation operation, which can perform a ventilation operation inside the rotating cylinder 505 through the third connecting pipe 805, so that the grinding debris can enter the rotating cylinder 505 through the first dust suction hole 801. Then, through the third connecting pipe 805 and the fan 804, it is transported through the pipeline to the external dust removal equipment for dust removal.

[0040] The main body of the device also includes a dust collection and cooling mechanism for dust collection and cooling of the moving blade module 102. The dust collection and cooling mechanism includes a dust collection hood 1001 connected to the blade mounting base 101, a second dust collection hole 1002 opened at the bottom of the dust collection hood 1001, and a fourth connecting pipe 1003 connecting the dust collection hood 1001 and the third connecting pipe 805. The dust collection hood 1001 is connected to the blade mounting base 101 through a second bracket 1004. When the third connecting pipe 805 is in the suction operation, the dust collection hood 1001 can be in the suction operation through the fourth connecting pipe 1003, thereby enabling the suction operation through the second dust collection hole 1002. This not only allows for dust collection of debris on the surface of the moving blade module 102, but also for cooling the moving blade module 102, improving the quality of the trimming. During dust collection, the suction power is controlled to ensure that only debris is absorbed, and the trimmed material is not adsorbed.

[0041] Working principle: When it is necessary to trim excess material at the EVA foam shoe sole molding line 1103, the electromagnet 404 is energized, which attracts the iron block 403, causing the metal plate 304 to move upward. Under the action of hydraulic pressure, the guide rod 303 can be moved into the fixed tube 302, thereby moving the moving plate 1204 and the pressure roller 1206 away from the guide wheel 1203. The first sleeve 201 slides along the side wall of the first sleeve rod 202. At the same time, under the action of hydraulic pressure, the second sleeve rod 602 can slide into the second sleeve 601, and drive the rotating cylinder 505 to move through the U-shaped frame 502. Furthermore, under the action of hydraulic pressure, the annular plate 703 can be moved into the annular cover 701, thereby driving the conical disc 104 to move.

[0042] Next, the EVA foam sole is placed between the guide wheel 1203 and the pressure roller 1206, with the mold parting line 1103 positioned within the guide wheel 1203. Then, the electromagnet 404 is de-energized. At this point, the metal plate 304 moves downward along the reservoir 301 under gravity, squeezing the hydraulic oil. Under the action of hydraulic pressure, the guide rod 303 is pushed away from the fixed pipe 302, thereby causing the moving plate 1204 and the pressure roller 1206 to move closer to the guide wheel 1203, so that the pressure roller 1206 abuts against the outsole 1102. The guide wheel 1203 abuts against the mold parting line 1103, which flattens the excess material on the mold parting line 1103. The moving blade module 102 flattens the excess material on the mold parting line 1103, and the moving blade module 102 fits against the trimming position. This ensures that the trimming position is always in contact with the moving blade module 102, making it more convenient and faster, and ensuring the efficiency and quality of trimming. In addition, the annular plate 703 can move away from the annular cover 701, driving the conical disc 104 to move synchronously and abut against the edge of the insole 1101, thereby limiting the EVA foam sole.

[0043] Then, the power and transmission components within the base 103 drive the telescopic transmission shaft 105 and the conical disc 104 to rotate, thereby enabling the feeding operation of the EVA foam sole. Under the gravity of the metal plate 304, the pressing roller 1206 is pushed to always abut against the outsole 1102. At the same time, the guide wheel 1203 abuts against the parting line 1103, ensuring a constant extrusion pressure. This adapts to the shape of the sole, allowing the guide wheel 1203 to always roll along the parting line 1103 during feeding, thus providing guidance and limiting functions. While feeding material, the moving blade module 102 trims the excess material on the mold line 1103. Furthermore, when the depth of the insole 1101 changes, the metal plate 304 ensures that the conical disc 104 always abuts against the edge of the insole 1101 under the gravity of the metal plate 304, thus ensuring the support and feeding effect of the EVA foam sole. This eliminates the need for operators to manually trim the EVA foam sole, making it more convenient and faster. In addition, it can limit and guide the EVA foam sole, preventing the sole from shifting or loosening, and improving the efficiency and quality of trimming.

[0044] Furthermore, during trimming, under the action of hydraulic pressure, the second sleeve rod 602 can be pushed to move away from the second sleeve tube 601, and the rotating cylinder 505 can be moved through the U-shaped frame 502, so that the grinding block 504 abuts against the trimmed mold line 1103. At the same time, the motor 903 is started, and the rotation of the motor 903 drives the rotation of the gear 904, which can drive the rotating tube 503 to rotate through the gear ring 901, and then drive the rotating cylinder 505 to rotate, so that the grinding block 504 can perform a grinding operation on the trimmed mold line 1103, improving the quality of trimming. The guide wheel 1203 rolls on the trimmed and ground mold line 1103.

[0045] When the rotating cylinder 505 rotates, it drives the brush 802 to rotate, thereby cleaning the debris from the grinding mold line 1103. At the same time, the fan 804 is started to perform a ventilation operation, which can perform a ventilation operation inside the rotating cylinder 505 through the third connecting pipe 805, so that the grinding debris can enter the rotating cylinder 505 through the first dust suction hole 801. Then, through the third connecting pipe 805 and the fan 804, it is transported through the pipeline to the external dust removal equipment for dust removal.

[0046] When the third connecting pipe 805 is in the exhaust operation, the dust suction hood 1001 can be vented through the fourth connecting pipe 1003, thereby enabling the second dust suction hole 1002 to perform the exhaust operation. This not only removes debris from the surface of the moving blade module 102, but also cools the moving blade module 102, improving the quality of the trimming. During the dust suction, the suction power is controlled to ensure that only debris is absorbed, and the trimmed material is not adsorbed.

[0047] After the trimming is completed, the metal plate 304 is moved upward again by the lifting assembly, which in turn moves the pressure roller 1206 away from the guide wheel 1203, so that the trimmed EVA foam sole can be removed.
