[0002] Automobile tires are one of the important parts of automobiles. They bear the weight of the automobile and are in direct contact with the road surface. The tread patterns of the tires can ensure good adhesion between the wheels and the road surface, ensuring the safety of the driving process. The processing of tire treads is receiving more and more attention. Therefore, in the process of tire processing and production, it is necessary to further cut or grind the tire tread so that the tread patterns of the tires can ensure sufficient adhesion between the wheels and the road surface.

[0003] Since tires come in a variety of sizes, and current tire cutting devices can only cut tires of a single size, if tires of different sizes need to be processed, it is necessary to purchase and replace a variety of different cutting devices, which leads to a significant increase in cutting costs.

[0045] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0046] refer to Figure 1 and Figure 2 The present application provides a tire cutting device, comprising: a base 10, a first sliding portion 20, a first supporting portion 30, a second supporting portion 40, a cutting driving portion 50 and a cutting machine 60, wherein: the base 10 is moved in a first direction (i.e. Figure 1 The first sliding portion 20 extends along the second direction (ie Figure 1 The first direction (ie, the Y direction) is provided on the base 10. Figure 1 The X direction shown) and the second direction (i.e. Figure 1 The first support portion 30 extends along the second direction and is spaced from the first sliding portion 20 along the first direction on the base 10. The first support portion 30 extends along the first direction (ie Figure 1 The base 10 is slidably connected to the base 10 in the X direction (as shown).

[0047] Among them, reference Figure 3 Combined with Figure 1 The second support portion 40 includes a driving device 401 and a telescopic device 402. One end of the driving device 401 is moved along the second direction (i.e. Figure 1 The first sliding part 20 is slidably connected to the first sliding part 20 in the Y direction shown in the figure. The driving device 401 is used to drive the telescopic device 402 to move in the first direction (i.e. Figure 1 When at least part of the telescopic device 402 is driven to rotate to a certain position (eg, Figure 1 The position shown) along the third direction (i.e. Figure 1 The Z direction shown in the figure) extends in the third direction (i.e. Figure 1 The Z direction shown in FIG. 1 ) intersects the first direction (ie Figure 1 The X direction shown) and the second direction (i.e. Figure 1 The telescopic device 402 is connected to the driving device 401 and is used to support the tire. The telescopic device 402 can be extended or shortened to support tires of different tire diameters.

[0048] Among them, reference Figure 2 , along the first direction (i.e. Figure 1 The cutting drive unit 50 is disposed on one side of the first support unit 30 and opposite to the second support unit 40. The cutting drive unit 50 is connected to the cutting machine 60 and is used to drive the cutting machine 60 to move in a third direction (i.e. Figure 1 The cutting machine 60 is used to cut the tire.

[0049] Exemplarily, the tire is supported by the telescopic device 402 and can be extended or shortened, so that when the tire diameter of the tire to be cut becomes larger, the telescopic device 402 can be extended, and when the tire diameter of the tire to be cut becomes smaller, the telescopic device 402 can be shortened to adapt to tires with different tire diameters; at the same time, one end of the driving device 401 is driven in the second direction (i.e. Figure 1 The first sliding part 20 is slidably connected to the first sliding part 20 in the Y direction shown in the figure. The driving device 401 is connected to the telescopic device 402 and drives the telescopic device 402 to slide. When the telescopic device 402 needs to install a tire, the driving device 401 drives the telescopic device 402 to slide along the Figure 1 The tire is then conveniently mounted on the telescopic device 402 in the Y direction as shown. After the tire is mounted, the telescopic device 402 is driven by the driving device 401 to slide to a position opposite to the cutting machine 60. At the same time, the driving device 401 can drive the telescopic device 402 to rotate around the first direction, thereby driving the tire to rotate, so that the cutting machine 60 can cut the rotating tire. This also facilitates cutting operations on the tire at different heights and different positions, thereby effectively improving the practicability of the cutting device.

[0050] Exemplarily, the first support portion 30 is used to support the Figure 1 The base 10 is slidably connected to the base 10 in the X direction (shown in the figure), so that the distance between the cutting machine 60 on the first support part 30 and the tire on the second support part 40 can be adjusted. When the tire needs to be installed, the first support part 30 can be moved along the Figure 1 The tire is moved away from the second support portion 40 in the direction b, and the distance between the first support portion 30 and the second support portion 40 is increased, which is convenient for operators to install the tire. When the tire has been installed, the first support portion 30 can be moved along the second support portion 40. Figure 1 The first support portion 30 slides in the a direction close to the second support portion 40, and the distance between the first support portion 30 and the second support portion 40 becomes smaller, small enough to accommodate the tire to be cut, and the cutting machine 60 can fit at the position where the tire is to be cut.

[0051] For example, the spacing between the first support portion 30 and the second support portion 40 can also be adjusted according to the size of the tire model. When the tire model is large, the first support portion 30 can be moved along the second support portion 40. Figure 1The tire can be moved away from the second support portion 40 in the direction b to increase the distance between the first support portion 30 and the second support portion 40. When the tire model is small, the first support portion 30 can be moved along the second support portion 40. Figure 1 The first support portion 30 and the second support portion 40 are slid in the a direction to approach the second support portion 40, thereby reducing the distance between the first support portion 30 and the second support portion 40, so as to achieve the purpose of adapting to different types of tires.

[0052] It should be noted that the embodiment of the present application is for the first direction (i.e. Figure 1 The X direction shown), the second direction (i.e. Figure 1 The Y direction shown) and the third direction (i.e. Figure 1 There is no specific limitation on the Z direction shown in the figure, as long as the first direction intersects with the second direction, and the third direction intersects with the second direction and the first direction respectively. For the convenience of display, the embodiments in this application are illustrated as if the first direction, the second direction and the third direction are perpendicular to each other.

[0053] For example, reference Figure 1 The base 10 is a rectangular plate, along Figure 1 In the Y direction shown, four support columns are provided at the bottom of the base 10 to contact the ground, and the base 10 is separated from the ground by the four support columns, thereby ensuring the stability of the base 10 during the cutting process. It should be noted that the present application does not limit the size and shape of the base 10, as long as it can play a supporting role, and does not limit the number, shape and size of the support columns, as long as the base 10 can be separated from the bottom surface and stably stand on the ground.

[0054] For example, reference Figure 1 and Figure 2 The base 10 has a first direction (i.e. Figure 1 The two slide rails extend in the X direction as shown in the figure, but are not limited thereto, and may also be one slide rail or three slide rails. Figure 1 The Z direction shown in FIG. 1 is a first slide rail 101 disposed on the left side of the base 10 and a second slide rail 102 disposed on the right side of the base 10. The first slide rail 101 and the second slide rail 102 are parallel and along the Figure 1 The Z-direction spacing shown is used to limit the movement of the third sliding portion 80 described later along the first direction.

[0055] For example, reference Figure 1 The first sliding part 20 includes: a lifting plate 201, a first driving part 202 and a threaded rod 203, wherein the lifting plate 201 moves along the second direction (i.e. Figure 1 The lifting plate 201 extends in the Y direction as shown in the figure, which can provide effective lifting and supporting functions, and is provided with a first slide groove 2011 extending in the second direction. The lifting plate 201 also includes a first slide groove 2011 extending in the third direction (i.e. Figure 1The guide grooves are arranged in a spaced relationship along the third direction (ie, the Z direction shown in the figure). The guide grooves include a first guide groove 2012 arranged on the left side of the first slide groove 2011 and a second guide groove 2013 arranged on the right side of the first slide groove 2011. The first guide block 702 of the second sliding portion 70 described later is arranged along the second direction (ie, the Z direction shown in the figure). Figure 1 The second guide block 703 of the second sliding portion 70 described later is slidably disposed in the first guide groove 2012 in the Y direction as shown in FIG. Figure 1 The second sliding portion 70 is slidably disposed in the second guide groove 2013 in the Y direction as shown, so as to limit the movement of the second sliding portion 70.

[0056] For example, reference Figure 1 , along the second direction (i.e. Figure 1 The first driving part 202 is provided at the top of the lifting plate 201, and a threaded rod 203 is installed in the first slide groove 2011. Along the second direction, one end of the threaded rod 203 is connected to the bottom end of the first slide groove 2011, and the other end passes through the top of the lifting plate 201 and is connected to the bottom end of the first driving part 202. The threaded rod 203 is connected to the second sliding part 70 described later. The first driving part 202 can drive the threaded rod 203 to rotate circumferentially to drive the second sliding part 70 to slide along the second direction.

[0057] It should be noted that the present application does not impose any specific restrictions on the number of guide grooves, and the number can be set to one or two, etc. The present application does not impose any specific restrictions on the type and specific installation position of the first driving part 202, as long as it can drive the threaded rod 203 to rotate circumferentially. For example, the first driving part 202 can be a motor or a cylinder, etc., and the first driving part 202 can be installed on the top of the lifting plate 201.

[0058] It should be noted that the present application does not impose any specific restrictions on the specific structure of the first sliding part 20. As long as the driving device 401 connected to the first sliding part 20 can move along the second direction (i.e. Figure 1 It can move up and down in the Y direction as shown, such as the structure of the lifting plate 201, the first driving part 202 and the threaded rod 203 shown in this embodiment, or the screw rod structure and the cylinder.

[0059] For example, reference Figure 1 Combined with Figure 3The telescopic device 402 includes a telescopic driving part 4021 and two telescopic rods arranged on opposite sides of the telescopic driving part 4021, including a first telescopic rod 4022 arranged on the right side of the telescopic driving part 4021 and a second telescopic rod 4023 on the left side of the telescopic driving part 4021. The telescopic driving part 4021 is connected to the other end of the driving device 401 and is used to drive the first telescopic rod 4022 and the second telescopic rod 4023 to move toward or away from each other along a third direction. The opposite ends of the first telescopic rod 4022 and the second telescopic rod 4023 are respectively connected to the telescopic driving part 4021.

[0060] For example, reference Figure 1 Combined with Figure 3 One end of the first telescopic rod 4022 that is opposite to the second telescopic rod 4023 is connected to the first support ring 4024, and one end of the second telescopic rod 4023 that is opposite to the first telescopic rod 4022 is connected to the second support ring 4025. The first support ring 4024 and the second support ring 4025 are both arc-shaped structures. When in a certain telescopic position, the two together form a circle along the circumferential direction, and the first support ring 4024 is provided with 7 first convex parts 40241 on the periphery, and the second support ring 4025 is provided with 7 second convex parts 40251 on the periphery, which are used to adapt to the inner side of the tire bead, so that the first support ring 4024 and the second support ring 4025 can support the tire more stably and prevent the tire from falling during the cutting process.

[0061] Exemplarily, the first support ring 4024 is detachably connected to the first telescopic rod 4022, and the second support ring 4025 is detachably connected to the second telescopic rod 4023. When the tire diameter of the tire to be supported changes, the first support ring 4024 and the second support ring 4025 that are compatible with the inner side of its tire bead can be selected according to actual needs, so that the first support ring 4024 and the second support ring 4025 can support the tire more stably and prevent the tire from falling off during the cutting process.

[0062] It should be noted that the present application does not impose any specific restrictions on the type of the driving device 401. As long as the type of the driving device 401 can be driven to rotate the telescopic device 402 in the first direction (i.e. Figure 1 The telescopic drive unit 4021 can be rotated in the X direction as shown, for example, a motor or a cylinder can be selected. The present application does not impose any specific restriction on the type of the telescopic drive unit 4021, as long as it can drive the first telescopic rod 4022 and the second telescopic rod 4023 to move toward or away from each other, for example, a motor or a cylinder can be selected.

[0063] It should be noted that the present application does not impose any specific restriction on the number of the first telescopic rod 4022, the second telescopic rod 4023, the first support ring 4024, the second support ring 4025, the first protrusion 40241 and the second protrusion 40251. For example, the first telescopic rod 4022 and the second telescopic rod 4023 can be set to two or four spaced along the periphery of the telescopic drive part 4021, the first support ring 4024 and the second support ring 4025 can also be set to two or four spaced along the periphery of the telescopic rod, and the first protrusion 40241 and the second protrusion 40251 can also be set to 5 or 7, etc.

[0064] For example, when the driving device 401 drives the telescopic device 402 to rotate in a first direction (i.e. Figure 1 X direction as shown) to Figure 1 When the tire diameter of the tire to be cut becomes larger, the telescopic driving unit 4021 drives the first telescopic rod 4022 to move along the Figure 1 The second telescopic rod 4023 moves in the direction c shown in FIG. Figure 1 The movement in direction d shown increases the distance between the first support ring 4024 connected to the first telescopic rod 4022 and the second support ring 4025 connected to the second telescopic rod 4023, so that the first support ring 4024 and the second support ring 4025 can be completely attached to the inner side of the tire bead to be cut, so that the tire remains stable during the cutting process and does not fall off.

[0065] Similarly, when the tire diameter of the tire to be cut becomes smaller, the telescopic driving unit 4021 drives the first telescopic rod 4022 to move along the Figure 1 The second telescopic rod 4023 moves in the direction d shown in FIG. Figure 1 The movement in direction c shown reduces the distance between the first support ring 4024 connected to the first telescopic rod 4022 and the second support ring 4025 connected to the second telescopic rod 4023, so that the first support ring 4024 and the second support ring 4025 can be completely attached to the inner side of the tire bead to be cut, so that the tire remains stable during the cutting process and does not fall off.

[0066] For example, reference Figure 3 Combined with Figure 1 The tire cutting device further includes a second sliding portion 70, the second sliding portion 70 including a Figure 3 The connecting plate 701 extending in the Z direction as shown, the slider 704 provided on the back of the connecting plate 701 and the slider 704 along the Figure 3The first guide block 702 is arranged on the left side of the slider 704 and the second guide block 703 is arranged on the right side of the slider 704 in the Z direction. The connecting plate 701 is connected to one end of the driving device 401, the slider 704 is provided with a through hole 7041 and is sleeved on the threaded rod 203, the slider 704 is threadedly connected to the threaded rod 203, and the first guide block 702 is arranged along the second direction (i.e. Figure 1 The second guide block 703 is slidably disposed in the first guide groove 2012 along the second direction (ie, the Y direction shown in FIG. Figure 1 The second sliding portion 70 is slidably disposed in the second guide groove 2013 in the Y direction as shown, so as to limit the movement of the second sliding portion 70.

[0067] It should be noted that the present application does not impose any specific restriction on the number of guide blocks, as long as it corresponds to the number of the above-mentioned guide grooves.

[0068] For example, reference Figure 1 and Figure 2 The tire cutting device further includes a third sliding part 80, which includes a sliding block 801, a second driving part 802 and a sliding telescopic rod 803, and can adjust the position of the cutting machine 60, wherein the sliding block 801 is arranged on the first slide rail 101 and the second slide rail 102, and is connected to the first support part 30, and can drive the first support part 30 to move along the first slide rail 101 and the second slide rail 102. The second driving part 802 and the sliding block 801 move along the first direction (i.e. Figure 1 The second driving part 802 is used to drive the sliding telescopic rod 803 to move along the first direction to drive the sliding block 801 to slide along the first direction.

[0069] When the tire size is large, the second driving unit 802 can be used to drive the sliding telescopic rod 803 along the Figure 1 The sliding block 801 moves synchronously with the sliding block 801, thereby driving the first support portion 30 to move along the Figure 1 b direction away from the second support portion 40, increasing the distance between the first support portion 30 and the second support portion 40, so that the tire can be placed in the current distance; when the tire model is small, the second driving portion 802 can drive the sliding telescopic rod 803 along Figure 1 The sliding block 801 moves synchronously with the first support portion 30, thereby driving the first support portion 30 to move along the Figure 1 The a direction is close to the second support portion 40, reducing the distance between the first support portion 30 and the second support portion 40, so that the tire can be placed in the current distance, thereby achieving the purpose of adapting to different types of tires.

[0070] It should be noted that the present application does not impose any specific restrictions on the specific composition structure of the third sliding portion 80. As long as the first support portion 30 connected to the third sliding portion 80 can be moved along the first direction (i.e. Figure 1 For example, the structure of the sliding block 801, the second driving part 802 and the sliding telescopic rod 803, or the screw rod structure and the cylinder are matched.

[0071] The tire cutting device of another embodiment of the present application also includes a chip guide box 90, which is provided with a chip guide opening (not shown in the figure). The chip guide box 90 is arranged on the side of the first support part 30 facing away from the cutting machine 60 and passes through the first support part 30. The chip guide opening (not shown in the figure) is arranged opposite to the cutting machine 60. The chip guide box 90 can provide guidance for waste chips and prevent waste chips from flying around, thereby preventing waste chips from entering the cutting device and affecting the life of the cutting device.

[0072] For example, reference Figure 1 and Figure 2 The chip guide box 90 is hollow in design, and a chip outlet (not shown) is provided at one end of the chip guide box 90 away from the chip guide opening (not shown in the figure). Figure 1 A first storage box 903 is provided below the chip outlet (not shown), and the first storage box 903 is connected to the first support portion 30. Figure 1 A second storage box 904 is provided below the cutting machine 60 , and the second storage box 904 is connected to the first supporting part 30 .

[0073] During the process of the cutting machine 60 cutting the tire, the chip guide box 90 is used to block one side of the cutting machine 60, so that the waste chips generated by the cutting can be conveniently guided to the inner side of the first storage box 903 for temporary storage through the chip guide box 90 and the inertia of the rotation of the cutting blade. At the same time, a second storage box 904 is provided under the cutting machine 60 to support the waste chips on the other side, which effectively improves the waste chip collection effect, facilitates rapid processing later, avoids damage to the cutting device by the waste chips, and improves the durability and service life of the device.
