Description

Technical Field

[0001] This utility model relates to the field of rubber shoe sole production technology, and in particular to a roller-type rubber sole grinding machine. Background Technology

[0002] Rubber soles are shoe soles made of rubber materials, which can be roughly divided into natural rubber or synthetic rubber. Based on the flexibility and excellent elasticity of rubber materials, rubber soles can provide good shock absorption for various sports.

[0003] During the production of rubber shoe soles, the soles need to be sanded to roughen them, facilitating subsequent processes such as gluing. Rubber shoe soles typically have varying thicknesses, and different sizes of rubber soles have different thickness variations. Therefore, when processing rubber soles of different sizes, improper pressure adjustment of the rubber sole sander can easily lead to insufficient pressure, making it difficult to form clear sanding patterns in thinner areas, or excessive pressure causing significant deformation in thicker areas, thus affecting the overall sanding effect of the rubber sole sander.

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0044] This utility model of a roller-type rubber sole grinding machine can adapt to different thicknesses of rubber shoe soles, ensuring clear grinding of the rubber shoe soles, effectively improving the grinding effect of rubber shoe soles, and at the same time effectively reducing damage to rubber shoe soles.

[0045] In one embodiment of this utility model, such as Figures 1 to 5 As shown, the roller-type rubber bottom grinding machine includes a support frame 1, a pressure roller assembly 2, and a transmission adapter 3. The pressure roller assembly 2 is rotatably mounted on the support frame 1 and has a grinding surface 201. The transmission adapter 3 is connected to the support frame 1 and is located below the pressure roller assembly 2.

[0046] The adapter transmission component 3 includes a transmission element 31 and several elastic adapters 32. The transmission element 31 moves relative to the pressure roller component 2 in a predetermined direction, which can be a horizontal movement direction from left to right or from right to left, or a rotation direction of clockwise or counterclockwise rotation around a fixed axis. Several elastic adapters 32 are spaced apart on the side of the transmission element 31 facing the pressure roller component 2. The elastic adapters 32 are adapted to extend and retract along their length to change the distance between the top of the elastic adapter 32 and the grinding surface 201. A rubber shoe sole is placed between the grinding surface 201 and the top of the elastic adapter 32.

[0047] According to the roller-type rubber sole roughening machine of this embodiment, the grinding surface 201 can roughen the rubber sole by grinding it. When the rubber sole is placed between the grinding surface 201 of the pressure roller component 2 and the top of the elastic adapter 32, several elastic adapters 32 located below the rubber sole will extend or retract a certain length according to the different thickness positions of the rubber sole, so that the distance between the top of the corresponding elastic adapter 32 and the grinding surface 201 is the same as the thickness of the rubber sole at the corresponding position, so as to ensure that the rubber sole and the grinding surface 201, and the rubber sole and the elastic adapter 32 can form stable contact. As a result, when the pressure roller component 2 grinds the rubber sole, the pressure roller component 2 can form clear grinding marks on the rubber sole, effectively improving the grinding effect of the rubber sole.

[0048] Meanwhile, the elastic adapter 32 can absorb the pressure applied to the rubber sole by the pressure roller component 2, so as to avoid the problem of deformation of the rubber sole due to excessive pressure and effectively reduce the damage to the rubber sole.

[0049] It should also be noted that by arranging several elastic adapters 32 on the transmission component 31 to adapt to the thickness of the rubber sole, the roller-type rubber sole grinding machine can process a variety of different specifications of sole products. Therefore, it is not necessary to adjust the roller-type rubber sole grinding machine according to different specifications of product models, which effectively improves the adaptability and grinding efficiency of the roller-type rubber sole grinding machine.

[0050] In one specific embodiment, the thickness of the rubber sole is h1 at the front, h2 at the middle, and h3 at the rear, where h3 is greater than h1 and h1 is greater than h2. When the rubber sole is placed between the grinding surface 201 and the elastic adapter 32, the distance between the top of the elastic adapter 32 at the front and the grinding surface 201 is h1, the distance between the top of the elastic adapter 32 at the middle and the grinding surface 201 is h2, and the distance between the top of the elastic adapter 32 at the rear and the grinding surface 201 is h3. This ensures that the distance between the top of the elastic adapter 32 and the grinding surface 201 in each area of ​​the rubber sole is the same as the thickness of the rubber sole at the corresponding position, ensuring stable contact between the rubber sole and the elastic adapter 32 and the grinding surface 201.

[0051] In this embodiment, to facilitate the transmission component 31 in conveying the rubber sole to the area below the pressure roller component 2, such as... Figures 1 to 3 As shown, the transmission component 31 is a roller rotatably connected to the equipment support 1, and several elastic adapters 32 are spaced apart on the outer surface of the roller facing the grinding surface 201. Each elastic adapter 32 includes an elastic element 321 and a column 322. The column 322 is connected to the outer surface of the roller, and the elastic element 321 is connected to the top of the column 322. At this time, the predetermined direction of relative movement between the transmission component 31 and the pressure roller component 2 is the rotation direction of the roller (which can be forward or reverse). The rubber sole can be placed on top of the elastic element 321. Under external pressure, the elastic element 321 undergoes a certain distance of elastic deformation. Subsequently, the rotation of the roller relative to the equipment support 1 moves the rubber sole to below the pressure roller component 2. Utilizing the elastic properties of the elastic element 321, the distance between the top of the elastic element 321 and the grinding surface 201 is changed to accommodate different thicknesses of the rubber sole.

[0052] Among them, such as Figure 4 and Figure 5As shown, the elastic element 321 is preferably a spring, which cooperates with the column 322 to form a spring column structure to accommodate different rubber sole thicknesses. The outer surface of the roller has several insertion holes 311. The end of the column 322 facing away from the spring is inserted into the insertion hole 311. Adjacent columns 322 are connected by a connecting bracket 323, so that the columns 322 are connected to form an integral column 322 system, ensuring the installation stability of the columns 322 within the roller.

[0053] Of course, the connection between the elastic element 321 and the column 322 is not limited to the elastic element 321 being connected to the top of the column 322. Alternatively, the elastic element 321 can be placed inside the insertion hole 311 of the roller, and then the lower end of the column 322 can be connected to the top of the elastic element 321. This ensures that when the elastic element 321 is in a stretched state, the lower end of the column 322 is inserted into the insertion hole 311, and the upper end of the column 322 protrudes out of the insertion hole 311.

[0054] It should also be noted that the transmission component 31 is not limited to a roller rotatably connected to the equipment support 1. In other embodiments, the transmission component 31 may also be a conveyor belt structure disposed on the equipment support 1 and located below the pressure roller component 2. The predetermined direction of relative movement between the transmission component 31 and the pressure roller component 2 is the transmission direction of the belt (i.e., Figure 2 (From left to right or from right to left). Multiple insertion holes 311 are arranged on the conveyor belt, and each elastic adapter 32 is inserted into the corresponding insertion hole 311 to ensure the connection stability between the elastic adapter 32 and the conveyor belt, and to ensure that several elastic adapters 32 can move with the conveyor belt toward the pressure roller component 2.

[0055] In this embodiment, as Figure 4 and Figure 5 As shown, a number of elastic adapters 32 are arranged in rows on the outer surface of the roller. In any two adjacent rows of elastic adapters 32, one row of elastic adapters 32 protrudes outward from the outer surface of the roller, while the other row of elastic adapters 32 is retracted into the roller. The adjacent rows of elastic adapters 32 protrude outward from the outer surface of the roller in an alternating manner.

[0056] Furthermore, when the roller is polishing the rubber sole supported by several elastic adapters 32, the elastic adapters 32 protruding from the outer surface of the roller can be used to adapt to different thicknesses of the rubber sole, while the elastic adapters 32 that retract can provide additional support for the roller, thereby reducing the direct pressure of the pressure roller component 2 on the roller, effectively reducing the amount of deformation of the roller under pressure, and extending the service life of the roller.

[0057] In this embodiment, as Figure 3As shown, the adapter transmission component 3 also includes a first drive component 33, which is used to drive the transmission component 31 to move relative to the pressure roller component 2, so as to transport the rubber shoe sole to the ground surface 201 of the pressure roller component 2 and complete the grinding operation of the pressure roller component 2.

[0058] Specifically, the first drive assembly 33 includes a connecting plate 331, a support bracket 332, and a first motor 333. The connecting plate 331 is disposed on the equipment bracket 1, and the support bracket 332 is connected to the connecting plate 331. The roller is rotatably connected to the support bracket 332 via a rotating shaft 334. The first motor 333 is disposed on the connecting plate 331, and the output shaft of the first motor 333 is rotatably connected to the rotating shaft 334 via a conveyor belt assembly 335. The output shaft of the first motor 333 can drive the rotating shaft 334 to rotate via the conveyor belt assembly 335, thereby driving the roller to rotate relative to the support bracket 332, thus conveying the rubber sole on the roller to below the grinding surface 201 of the pressure roller assembly 2.

[0059] It should be noted here that, as Figure 3 As shown, the conveyor belt assembly 335 includes a drive wheel, a driven wheel, and a V-shaped conveyor belt. The drive wheel is connected to the output shaft of the first motor 333 via a key, and the driven wheel is connected to the rotating shaft 334 via a key. The V-shaped conveyor belt is fitted onto the drive wheel and the driven wheel so as to transmit the rotational motion of the output shaft of the first motor 333 to the rotating shaft 334, so that the rotating shaft 334 drives the drum to rotate.

[0060] In one specific embodiment, when the elastic adapter 32 extends the longest on the outer surface of the roller, the distance between the top of the elastic adapter 32 and the rotating shaft 334 is D1, and the height of the support bracket 332 is H1, where H1 is greater than D1, so as to ensure that when the roller drives the elastic adapter 32 to rotate relative to the support bracket 332, the connecting plate 331 will not interfere with the rotation of the roller and the elastic adapter 32.

[0061] Of course, in order to ensure the space utilization rate inside the roller-type rubber bottom grinding machine, the connecting plate 331 can also be formed with a clearance groove. The clearance groove is located below the roller, and the length of the clearance groove is greater than the diameter of the roller. The clearance groove is used to clear the rotation of the roller, which can also prevent the connecting plate 331 from interfering with the rotation of the roller and the elastic adapter 32.

[0062] In embodiments of this utility model, such as Figure 1 and Figure 2As shown, the adapter transmission component 3 also includes a conveying component 34. The conveying component 34 is arranged at intervals along a predetermined direction and is located on both sides of the pressure roller component 2. The conveying component 34 is used to convey the rubber sole to the transmission component 31 so that the rubber sole is conveyed between the transmission component 31 and the grinding surface 201 of the pressure roller component 2 for grinding the rubber sole; or to convey the rubber sole out of the transmission component 31 so that the ground rubber sole can be taken out from the roller rubber sole roughening machine so that the roller rubber sole roughening machine can complete the subsequent grinding operation and facilitate the operator to transfer the ground rubber sole to the subsequent process.

[0063] Specifically, such as Figure 1 and Figure 2 As shown, the conveying assembly 34 includes one or more of a conveyor belt, a conveyor chain, or a conveyor rod. For example, a conveyor belt, conveyor chain, or conveyor rod can be arranged on both sides of the pressure roller assembly 2, or a conveyor belt can be arranged on the side of the pressure roller assembly 2 where the rubber sole is input and a conveyor chain can be arranged on the side where the rubber sole is output, or a conveyor chain can be arranged on the side where the rubber sole is input and a conveyor belt on the other side. The specific arrangement can be selected according to actual needs. The specific structure of the conveyor belt, conveyor chain, or conveyor rod is prior art and will not be described in detail here.

[0064] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, the adapter transmission component 3 also includes an extrusion assembly 35, which is disposed on the equipment support 1 and located on both sides of the pressure roller component 2. The extrusion assembly 35 has an extrusion surface 351, which is located above the transmission component 31. The extrusion surface 351 is used to press the rubber sole of the input transmission component 31 against the elastic adapter 32. Thus, before the rubber sole is fed into the space between the elastic adapter 32 and the grinding surface 201 of the pressure roller component 2, the rubber sole can be extruded by the extrusion assembly 35 to ensure sufficient contact between the rubber sole of the input transmission component 31 and the elastic adapter 32, and to be conveyed to the processing area between the elastic adapter 32 and the grinding surface 201 under the drive of the transmission component 31. This ensures the processing efficiency of the roller-type rubber sole roughening machine on the rubber sole and avoids the rubber sole from warping inside the roller-type rubber sole roughening machine, which would affect the grinding process of the rubber sole.

[0065] Specifically, such as Figure 8 and Figure 9As shown, the extrusion assembly 35 includes a vertical adjustment member 352 and a vertical pressure block 353. One end of the vertical adjustment member 352 is rotatably connected to the equipment bracket 1, and the other end of the vertical adjustment member 352 is connected to the vertical pressure block 353. The extrusion surface 351 is the bottom surface of the vertical pressure block 353 facing the elastic adapter 32. By rotating the vertical adjustment member 352, the distance between the extrusion surface 351 of the vertical pressure block 353 and the elastic adapter 32 is adjusted accordingly to accommodate rubber soles of various thicknesses. This ensures the extrusion effect of the vertical pressure block 353 on the rubber sole while preventing the conveying of the rubber sole from being blocked due to the insufficient distance between the extrusion surface 351 and the elastic adapter 32.

[0066] Vertical guide blocks 354 are arranged on both sides of the vertical pressure block 353. The vertical guide blocks 354 are fixed to the equipment bracket 1 and extend vertically to limit the movement direction of the vertical pressure block 353 and ensure the adjustment effect of the vertical adjustment component 352 on the vertical pressure block 353.

[0067] Preferably, the vertical adjustment component 352 is an adjustment screw, and the equipment bracket 1 is connected to an adjustment block. The top end of the vertical adjustment component 352 is rotatably connected to the adjustment block, and the bottom end of the vertical adjustment component 352 is threadedly connected to the vertical pressure block 353 so that the vertical pressure block 353 can move up and down when the vertical adjustment component 352 rotates.

[0068] In some embodiments, the bottom of the vertical pressure block 353 is rotatably connected to a roller, and the extrusion surface 351 is the outer surface of the roller. When the rubber sole is conveyed into the transmission component 31, the rubber sole can form a rolling engagement with the roller to ensure that the vertical pressure block 353 can vertically limit the rubber sole while avoiding interference with the movement of the rubber sole.

[0069] Furthermore, such as Figure 8 and Figure 9 As shown, to further prevent the rubber sole input transmission component 31 from tilting upwards, the extrusion assembly 35 also includes a horizontal adjustment component 355 and a horizontal guide block 356. The horizontal guide block 356 is slidably connected to the bottom surface of the vertical pressure block 353. One end of the horizontal adjustment component 355 is rotatably connected to the horizontal guide block 356, and the other end of the horizontal adjustment component 355 is rotatably connected to the vertical pressure block 353. The horizontal adjustment component 355 extends in a predetermined direction. The extrusion surface 351 is the bottom surface of the horizontal guide block 356 facing the elastic adapter 32. By rotating the horizontal adjustment component 355, the distance between the horizontal guide block 356 and the pressure roller component 2 can be adjusted, so that the bottom surface of the horizontal guide block 356 can be as close as possible to the pressure roller component 2, thereby further preventing the rubber sole input transmission component 31 from tilting upwards and further ensuring the processing effect of the pressure roller component 2 on the rubber sole.

[0070] Preferably, a guide rail is arranged above the horizontal guide block 356, and a groove is formed on the bottom surface of the vertical pressure block 353, which is slidably connected to the guide rail. The horizontal adjustment component 355 is an adjustment screw, and the horizontal guide block 356 is provided with a connecting block. The first end of the horizontal adjustment component 355 is rotatably connected to the connecting block, and the last end of the horizontal adjustment component 355 is threadedly connected to the vertical pressure block 353, so that when the horizontal adjustment component 355 rotates, it can drive the horizontal guide block 356 to slide relative to the vertical pressure block 353.

[0071] Preferably, the extrusion surface 351 of the underwater guide block is an inclined guide surface that is inclined downwards to adapt to rubber soles of different thicknesses.

[0072] In embodiments of this utility model, such as Figure 6 and Figure 7 As shown, the pressure roller component 2 includes a second motor 21, a drive shaft 22, and a pressure roller 23. A grinding surface 201 is formed on the outer surface of the pressure roller 23. The second motor 21 is mounted on the equipment support 1. The drive shaft 22 is rotatably connected to the equipment support 1. The pressure roller 23 is rotatably connected to one end of the drive shaft 22, and the other end of the drive shaft 22 is rotatably connected to the second motor 21. Thus, the second motor 21 can drive the drive shaft 22 to rotate, thereby driving the pressure roller 23 to rotate. When the transmission component 31 conveys the rubber sole to below the grinding surface 201 of the pressure roller 23, the pressure roller 23 can rotate relative to the rubber sole, achieving the grinding operation on the rubber sole.

[0073] The second motor 21 can be fixed to the bottom of the equipment bracket 1 by fasteners such as bolts or studs. The output shaft of the second motor 21 is equipped with a drive wheel, and the other end of the transmission shaft 22 is equipped with a driven wheel. The drive wheel and the driven wheel are connected by a conveyor belt to improve the installation stability of the second motor 21 while ensuring the transmission efficiency of the second motor 21 driving the pressure roller 23 to rotate.

[0074] Furthermore, a connecting bracket is connected to the middle of the drive shaft 22 via a bearing, and a telescopic cylinder (not shown in the figure) is connected above the connecting bracket. The fixed end of the telescopic cylinder is fixed to the equipment bracket 1, so that the connecting bracket can be moved up and down by the telescopic end of the telescopic cylinder, which in turn drives the drive shaft 22 to move up and down, thereby adjusting the installation height of the pressure roller 23. This further improves the adjustment range of the distance between the grinding surface 201 of the pressure roller 23 and the top of the elastic adapter 32, thereby further improving the adaptability of the roller-type rubber sole grinding machine to rubber soles of different specifications.

[0075] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 10As shown, the roller-type rubber bottom grinding mill also includes a lifting component 4 installed on the equipment support 1, and the lifting component 4 is located below the adapter transmission component 3. The lifting component 4 can be used to drive the adapter transmission component 3 to move up and down so as to maintain the adapter transmission component 3 without having to contact the pressure roller component 2 above the adapter transmission component 3, so that the maintenance operations of the adapter transmission component 3 and the pressure roller component 2 will not interfere with each other.

[0076] Specifically, such as Figure 10 As shown, the lifting component 4 includes a first support plate 41, a lifting cylinder 42, and multiple first telescopic supports 43. The first support plate 41 is connected to the equipment bracket 1 and is located below the adapter transmission component 3. The fixed end of the lifting cylinder 42 is disposed on the first support plate 41, and the telescopic end of the lifting cylinder 42 is connected to the adapter transmission component 3. Therefore, when maintenance of the adapter transmission component 3 is required, the telescopic end of the lifting cylinder 42 can be used to lower the adapter transmission component 3, moving it away from the pressure roller component 2 and below the equipment bracket 1, thus facilitating maintenance. When grinding of the rubber sole is required, the telescopic end of the lifting cylinder 42 can be used to raise the adapter transmission component 3, bringing it closer to the pressure roller component 2, so that the adapter transmission component 3 can be used to support the rubber sole.

[0077] Multiple first telescopic supports 43 are evenly distributed around the lifting cylinder 42, and the fixed ends of the first telescopic supports 43 are fixed to the first support plate 41. The telescopic ends of the first telescopic supports 43 are connected to the adapter transmission component 3. The multiple first telescopic supports 43 can support the adapter transmission component 3 when the lifting cylinder 42 extends, thereby improving the installation stability of the adapter transmission component 3.

[0078] In this embodiment, as Figure 10 As shown, the telescopic end of the lifting cylinder 42 is connected to the connecting plate 331, and the telescopic ends of the multiple first telescopic pillars 43 are all connected to the connecting plate 331, so that the lifting cylinder 42 can drive the first motor 333, the support bracket 332 and the roller above the connecting plate 331 to move up and down, thereby adjusting the height of the adapter transmission component 3.

[0079] Furthermore, to improve the grinding precision and effect of roller-type rubber sole roughening machines on rubber shoe soles, such as... Figure 10 As shown, the lifting component 4 also includes a second support plate 44, a processing amount adjustment component 45, and a plurality of second telescopic support columns 46. The second support plate 44 is fixed to the equipment bracket 1 and is located below the first support plate 41. A height adjustment screw 47 is provided between the first support plate 41 and the second support plate 44. The processing amount adjustment component 45 is threadedly connected to the height adjustment screw 47.

[0080] Understandably, when grinding the rubber sole, the processing amount adjustment component 45 can be rotated at a certain angle, causing the height adjustment screw 47 to rotate at a certain angle. Under the action of the thread, the height adjustment screw 47 rises to a certain height, thereby causing the first support plate 41 and the matching transmission component 3 on the first support plate 41 to rise to a certain height. This allows for fine adjustment of the rising height of the matching transmission component 3, correspondingly fine-tuning the distance between the elastic adapter 32 and the grinding surface 201 of the pressure roller component 2. Furthermore, if the texture of the rubber sole is shallow or not clear enough after grinding, the processing amount adjustment component 45 can be used to fine-tune the distance between the elastic adapter 32 and the grinding surface 201 of the pressure roller component 2. This slightly increases the processing amount of the pressure roller component 2 on the rubber sole, increasing the depth of the texture formed after grinding, and ensuring the grinding accuracy and effect of the rubber sole.

[0081] Multiple second telescopic supports 46 are evenly distributed around the height adjusting screw 47, and the fixed ends of the second telescopic supports 46 are fixed to the second support plate 44. The telescopic ends of the second telescopic supports 46 are connected to the first support plate 41. The multiple second telescopic supports 46 can support the first support plate 41 when the height adjusting screw 47 rises, further improving the installation stability of the adapter transmission component 3 on the first support plate 41.

[0082] As a specific example, such as Figure 10 As shown, the processing amount adjustment component 45 can be a rocker wheel. The rocker wheel is rotatably connected to the lower part of the second support plate 44 via a screw. A bevel gear set is arranged below the second support plate 44. The rocker wheel is meshed with one of the bevel gears via a screw, and the height adjustment screw 47 is meshed with the other bevel gear. By rotating the rocker wheel by a certain angle, the bevel gear set is driven to rotate, and the bevel gear set drives the height adjustment screw 47 to rotate by the corresponding angle, thereby achieving a slight adjustment of the height of the adapter transmission component 3, thus slightly increasing the processing amount of the pressure roller component 2 on the rubber shoe sole.

[0083] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
