Description

Technical Field

[0001] The invention relates to the technical field of waste tire recycling equipment, in particular to a tire cutting machine. Background Art

[0002] With the continuous development of society, cars have generally become a major means of transportation. Therefore, the number of waste tires will gradually increase. In some places in my country, waste tires are still treated in primitive ways such as incineration and landfill, or even discarded at will, causing "black pollution". Therefore, the recycling and reuse of waste tires can not only save a lot of resources, but also reduce pollution to the environment.

[0003] The treatment of waste tires generally includes the following process: breaking the tires into small pieces, then grinding the small pieces of tires, and then sorting and recycling them. The final recycled products mainly include rubber, steel wires and fibers embedded in the rubber, etc.

[0004] Therefore, how to divide the whole tire into small pieces for subsequent recycling has become the primary problem to be solved in the entire tire recycling process. In order to cut the waste tires into pieces, the waste tire processing equipment previously applied for by the applicant provides an implementation scheme, which uses an interlocking double-axis machine to tear the tires into small pieces. However, the applicant found in the specific implementation of the scheme that the equipment is relatively large and requires a relatively large installation site for equipment installation. At the same time, its efficiency can only be demonstrated when processing in large quantities. If the processing volume is relatively small, its power consumption is significantly higher. At the same time, the equipment cost is also relatively high, which is not suitable for the needs of small factories and small batch processing.

[0005] Therefore, developing a waste tire treatment solution that is more suitable for various needs will be more conducive to recycling waste tires more flexibly and efficiently. Summary of the invention

[0044] Below, the present invention is described in priority in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0046] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be fixedly connected, detachably connected, or integrally connected; it can be mechanically connected or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] Implementation method:

[0048] See also Figure 1-13The present invention shows a tire block cutting machine, comprising a cutting device 1, a feeding device 2, a leaking device 3, a discharging device 4 and a driving device 5, wherein the driving device 5 is used to drive the feeding device 2, the cutting device 1 and the discharging device 4; the feeding device 2 is used to convey strip-shaped tire strips to the cutting device 1; the cutting device 1 is used to cut the strip-shaped tire strips into block-shaped tire blocks; the leaking device 3 is used to leak the tire blocks cut into blocks into the discharging device 4; the discharging device 4 is used to output the tire blocks cut into blocks. That is, under the drive of the driving device 5, the strip-shaped tire strips are conveyed to the cutting device 1 through the feeding device 2, and the cutting device 1 is used to cut the strip-shaped tire strips into smaller tire blocks, and the cut tire blocks fall into the discharging device 4 through the leaking device 3, and the discharging device 4 is driven by the driving device 5 to output the tire blocks cut into smaller blocks, so that the strip-shaped tire strips are quickly cut into smaller tire blocks, reducing the work intensity of subsequent tire sheet crushing and improving production efficiency.

[0049] Specifically, the cutting device 1 includes a mounting base 13, a cutting platform 11 and a rotating cutting assembly 10. The mounting base 13 is mounted on the material leaking device 3 and is used to fix the rotating cutting assembly 10 and the cutting platform 11, that is, the rotating cutting assembly 10 is fixedly mounted on the mounting base 13, and the cutting platform 11 is also fixed on the mounting base 13. Preferably, a fixing plate 112 is provided at both ends of the cutting platform 11, the bottom end of the fixing plate 112 is fixed on the mounting base 13, and the top end of the fixing plate 112 extends in the vertical direction, so that the top end surface of the fixing plate 112 is higher than the plane of the cutting platform 11. The cutting platform 11 is fixed to the fixing plate 112 by means of screws, so that when the cutting platform 11 is worn, it can be replaced to ensure the flatness of the platform. Of course, the cutting platform 11 is horizontally arranged on the front side of the rotating cutting assembly 10, and an entrance 110 is arranged at the front end of the cutting platform 11. With the help of the driving device 5 and the feeding device 2, the strip-shaped tire strip is fed into the cutting platform 11 from the entrance 110. That is, it can be understood that under the drive of the driving device 5, the feeding device 2 feeds the strip-shaped tire strip from the entrance 110 into the cutting platform 11, and uses the rotating cutting assembly 10 to cut the tire strip.

[0050] The rotating cutting assembly 10 includes a rotating assembly and a cutting blade block 101, wherein the rotating assembly is fixed on the mounting base 13, and the rotating assembly can rotate under the drive of the driving device 5, and the cutting blade block 101 is mounted on the rotating assembly, so that the cutting blade block 101 can rotate with the rotation of the rotating assembly. Preferably, the rotating assembly includes a rotating shaft 100 and a blade block mounting seat 102, wherein the rotating shaft 100 can rotate under the drive of the driving device 5, and the blade block mounting seat 102 is mounted on the rotating shaft 100, and the cutting blade block 101 is fixed on the blade block mounting seat 102, so that the cutting blade block 101 can rotate with the rotation of the rotating shaft 100. That is, it can be understood that the cutting blade block 101 is fixed on the blade block mounting seat 102 by screws, and the cutting blade block 101 can be replaced when it is worn. The blade mounting seat 102 is key-connected to the rotating shaft 100 so that the blade mounting seat 102 rotates with the rotating shaft 100 , and the cutting blade block 101 is fixed on the blade mounting seat 102 , and multiple cutting blade blocks 101 can be provided to improve cutting efficiency and reduce wear of the cutting blade block 101 .

[0051] Of course, the cutting blade block 101 is mounted on the rotating assembly and is set at an angle to the cutting platform 11, that is, the cutting blade block 101 is set on the blade block mounting seat 102 and connected to the rotating shaft 100 through the blade block mounting seat 102, so that the cutting blade block 101 can rotate with the rotation of the rotating shaft 100, and the cutting blade block 101 can cut the strip-shaped tire strip into block-shaped tire blocks with the assistance of the cutting platform 11 during the rotation process. That is, it can be understood that Figure 3 As shown, the cutting edge of the cutting blade block 101 is the first cutting edge 1010, and the second cutting edge 111 is arranged on the cutting platform 11. When the cutting blade block 101 rotates to the second cutting edge 111 of the cutting platform 11, that is, the cutting edge (first cutting edge 1010) of the cutting blade block 101 contacts the upper plane of the strip-shaped tire strip, and the second cutting edge 111 of the cutting platform 11 contacts the lower plane of the strip-shaped tire strip, and the cutting platform 11 is horizontally arranged and stationary, and the cutting blade block 101 rotates with the rotation of the rotating shaft 100, thereby cutting the strip-shaped tire strip into block-shaped tire blocks.

[0052] In this preferred embodiment, in order to cut better, the angle between the cutting blade block 101 and the cutting platform 11 is set in the range of 3 to 6 degrees. By setting the cutting blade block 101 at an angle to the cutting platform, an incision is formed first during the cutting process, which makes it easier to cut. In addition, compared with setting the first cutting edge of the cutting blade block and the second cutting edge of the cutting platform in parallel, the cutting line contact can be changed to cutting point contact in the initial stage of cutting, and the resistance received by the cutting blade block 101 will be significantly reduced, making it easier to cut. Of course, when there are multiple cutting blade blocks 101 (such as three or four cutting blade blocks 101) arranged on the blade block mounting seat 102, when there are three cutting blade blocks 101 arranged on the blade block mounting seat 102, one cutting blade block 101 is arranged with a cutting direction opposite to that of the other cutting blade blocks 101, that is, if the cutting direction of two of the cutting blade blocks 101 is to the left, then the cutting direction of one is to the right; or, if the cutting direction of two of the cutting blade blocks 101 is to the right, then the cutting direction of one of the cutting blade blocks 101 is to the left. When there are four cutting blades 101, the cutting directions of two adjacent cutting blades 101 can be opposite, or two adjacent cutting blades 101 can be set to form a group, and the cutting directions of the two cutting blades 101 in each group are opposite to the cutting directions of the two cutting blades 101 in another group. In short, the multiple cutting blades 101 set on the blade mounting seat 102 adapt to the change of the different cutting directions of the cutting blades 101 in a reasonable manner, and all fall within the protection scope of the present invention. Since the tire strip will wear the cutting platform 11 during the cutting process, if it is only cut from one side, it is easy to cause unilateral wear and reduce the service life of the cutting platform. Through the above-mentioned setting of different cutting directions of the cutting blade blocks, the focus point during cutting can be changed, so that the wear on the cutting platform is dispersed to both sides, which can increase the service life of the cutting platform.

[0053] In this preferred embodiment, Figure 4 As shown, the rotating assembly further includes a disc 103, which is arranged at both ends of the blade block mounting seat 102 and is close to the end surface of the blade block mounting seat 102. The disc 103 is installed on the rotating shaft 100, that is, the disc 103 is connected to the rotating shaft 100 through a key, so that the disc 103 can rotate with the rotation of the rotating shaft 100. It can be understood that the setting of the disc 103 has a certain tightening effect on the blade block mounting seat 102, so that the blade block mounting seat 102 rotates more smoothly with the rotating shaft 100. At the same time, the disc 103 can limit the tire blocks cut into blocks to prevent the tire blocks from splashing everywhere, which is beneficial to protecting the equipment.

[0054] In this preferred embodiment, Figure 3-7As shown, the rotating assembly is also sleeved with a sleeve 12. Specifically, bearings are installed on the rotating shaft 100, and the bearings are located at both ends of the disc 103. The inner ring of the bearing cooperates with the rotating shaft 100, and the outer ring of the bearing is installed with a first bearing seat 1000 for fixing the sleeve 12, that is, the sleeve 12 is fixed to the rotating shaft 100 through the bearing and the first bearing seat 1000, and is used to fix the feeding device 2, and the sleeve 12 is fixed to the mounting base 13, so that the rotating assembly is fixed to the mounting base 13. Of course, a notch 120 is opened on the sleeve 12, and the notch 120 is in a "convex" shape, and the notch 120 enables the cutting blade 101 to be used to cut strips of tire strips during the rotation process, and the tire blocks cut into blocks can enter the sleeve 12 from the notch 120. That is, it can be understood that the two sides of the notch 120 on the sleeve 12 are connected to the fixing plate 112, and the circumferential surface of the disc 103 is close to the side of the fixing plate 112, but does not affect the rotation of the disc 103, so that the tire blocks cut into blocks enter the sleeve 12 from the notch 120, and the cut blocks are prevented from flying out from both sides of the notch 120.

[0055] As the preferred embodiment of the present invention, Figure 4-5 As shown, a heat dissipation cavity 10000 is provided on one end face of the first bearing seat 1000 along the circumferential direction, and a plurality of heat dissipation ribs 10001 are provided between the upper wall and the lower wall of the heat dissipation cavity 10000. That is, it can be understood that by providing the heat dissipation cavity 10000 on the end face of the first bearing seat 1000 and the heat dissipation ribs 10001 provided between the upper wall and the lower wall of the heat dissipation cavity 10000, the heat dissipation area for the bearing installation portion can be increased, so that the heat generated by the bearing when the rotating shaft 100 runs at a high speed can be quickly taken away, thereby achieving the effect of rapid heat dissipation, thereby improving the service life of the bearing. In addition, the heat dissipation ribs 10001 of the present invention can also strengthen the structural strength of the outer wall for installing the bearing portion, thereby improving the service life of the first bearing seat 1000.

[0056] As a preferred embodiment of the present invention, the heat dissipation ribs 10001 are evenly spaced, so that the heat dissipation of the bearing installation part is more uniform. Figure 5 As shown, the first bearing seat 1000 has a bearing hole 10002 for installing the bearing, and the heat dissipation cavity 10000 is coaxially arranged with the bearing hole 10002, so that the heat generated by the bearing when running at high speed in the bearing hole 10002 can be evenly dispersed into the heat dissipation cavity 10000 along the heat dissipation ribs 10001, thereby achieving a better heat dissipation effect.

[0057] In this preferred embodiment, Figure 8As shown, the feeding device 2 includes a rotating shaft 20 and a rotating shaft mounting frame 21. The rotating shaft mounting frame 21 is fixed to the cutting device 1 and is used to fix the rotating shaft 20 but does not affect the rotation of the rotating shaft 20, that is, one end of the rotating shaft mounting frame 21 is fixed to the outer wall of the sleeve 12, and the other end of the rotating shaft mounting frame 21 is fixed to the rotating shaft 20 by means of a bearing and a second bearing seat 201. A feeding wheel 200 is installed on the rotating shaft 20, so that the feeding wheel 200 can rotate with the rotation of the rotating shaft 20. The feeding wheel 200 is provided with saw teeth 2000, which are used to bite the strip of tire and convey the strip of tire to the cutting device 1 with the rotation of the feeding wheel 200. Of course, in order to facilitate the saw teeth 2000 to bite the strip-shaped tire strip, the saw teeth 2000 are arranged along the length direction of the rotating shaft 20, so that the strip-shaped tire strip can be smoothly sent into the cutting platform 11 from the entrance 110 of the cutting platform 11 under the drive of the driving device 5, and the cutting knife block 101 is used to cut the strip-shaped tire strip during the rotation process, and the cut tire blocks enter the sleeve 12 from the notch 120 of the sleeve 12.

[0058] In this preferred embodiment, Figure 9-12 As shown, the leakage device 3 includes an outer cover box 30 and a leakage box 31. The outer cover box 30 is arranged below the cutting device 1, that is, the outer cover box 30 is arranged below the mounting base 13 in the cutting device 1, and is used to fix the cutting device 1. The leakage box 31 is installed in the outer cover box 30 and is located below the mounting base 13, and the inner cavity of the leakage box 31 is communicated with the inner cavity of the sleeve 12, so that the tire blocks cut into blocks can enter the leakage box 31. Specifically, a through hole 130 communicating with the inner cavity of the sleeve 12 is formed at the lower end of the mounting base 13, and an opening 310 is also formed at the upper end of the leakage box 31, so that the inner cavity of the leakage box 31 communicates with the inner cavity of the sleeve 12, and further, when the cutting knife block 101 cuts the strip-shaped tire strips into block-shaped tire blocks, the cut block-shaped tire blocks enter the leakage box 31 from the notch 120 of the sleeve 12.

[0059] In this preferred embodiment, the discharging device 4 includes a fixed frame 40 and a conveyor belt 41. The fixed frame 40 is mounted inside the outer cover box 30 and extends outside the outer cover box 30. The conveyor belt 41 is installed on the fixed frame 40 and is located below the leakage box 31. The lower end of the leakage box 31 is provided with a leakage port 311, so that the tire blocks cut into blocks fall from the leakage port 311 onto the conveyor belt 41. The transmission of the conveyor belt 41 is driven by the driving device 5, so that the tire blocks cut into blocks are output. Since the conveying plane of the conveyor belt is a certain distance away from the cutting platform 11, and the outer cover box 30 and the sleeve 12 enclose the space between the cutting platform 11 and the conveyor belt, the dust generated during the cutting process is prevented from floating everywhere, polluting the processing environment, and also affecting the health of the operator. Through actual operation, when the outer cover box 30 is not set and the cut tire blocks are directly discharged through an outlet, the workers will be covered with black tire powder after working for 4 hours (i.e. half a day). However, after the outer cover box is set, the black tire powder on the workers is not obvious.

[0060] In this preferred embodiment, Fig.13 As shown, the driving device 5 includes a first driving mechanism and a second driving mechanism, wherein the first driving mechanism is used to synchronously drive the rotation of the rotating shaft 20 and the rotating shaft 100. The first driving mechanism includes a motor fixing bracket 50 and a motor 51, wherein the motor fixing bracket 50 is used to fix the motor 51, and the output shaft of the motor 51 is connected with a driving pulley 52 for protecting the driving pulley 52. ​​A driven pulley 53 is keyed to one end of the rotating shaft 100, and the driving pulley 52 and the driven pulley 53 are connected by a belt, so that the rotation of the rotating shaft 100 is driven by the drive of the motor 51 under the transmission of the belt. Of course, a driving sprocket 54 is provided at the other end of the rotating shaft 100, and a driven sprocket 55 corresponding to the driving sprocket 54 is provided on the rotating shaft 20, and the driving sprocket 54 and the driven sprocket 55 are connected by a transmission chain, so that the rotation of the rotating shaft 20 is synchronously driven by the rotation of the rotating shaft 100 under the transmission of the transmission chain. The second driving mechanism is preferably a servo motor (not shown), which is fixed on a fixed frame 40 in the discharge device 4, and is used to drive the transmission of the conveyor belt 41. The servo motor is connected to the conveyor belt 41 through the output shaft of the motor 51, thereby driving the transmission of the conveyor belt 41 through the drive of the motor 51.

[0061] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
