[0002] Recycled rubber refers to waste rubber products that have been processed to restore or improve their performance to a certain extent so that they can be reused.
[0003] When preparing the rubber ring, first select a rubber carcass with a suitable diameter. The rubber carcass is similar to a bicycle inner tube. Put the rubber carcass on a conveyor belt and use the continuously feeding conveyor belt to drive the carcass to move. The carcass is continuously moved up and down to cut the carcass at equal distances to obtain rubber rings of equal width.
[0004] When the above-mentioned rubber ring is produced, only a clamping block is set on one side of the cutting knife to clamp the tire body. However, when the already curved tire body is subjected to the friction of the conveyor belt in an unlimited state, the tire body itself will flip over, causing the user to constantly manually flip the tire body to reduce the degree of torsion of the tire body itself.

However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that the description of the present disclosure will be more comprehensive and complete and the concepts of the example embodiments will be fully conveyed to those skilled in the art. The accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and thus their repeated description will be omitted.
[0023] In addition, the described features, structures or characteristics may be combined in one or more example embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the example embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, steps, etc. may be adopted. In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.
[0024] Example 1
[0025] like Figure 1-Figure 4 A recycled rubber cutting die assembly is used to cut a whole rubber carcass into a plurality of rubber rings, which can be used for sealing of sealing parts.
[0026] The mold assembly includes a base 1 and a cover plate 2.
[0027] The base 1 includes a base body 11 and a connector 12. The base body 11 is placed on a workbench. The base body 11 and the connector 12 are fixedly connected while a gap is retained. The cutting knife driven by the power mechanism can pass through the gap when moving up and down and cut the rubber carcass on the path.
[0028] The above-mentioned technology of the power mechanism driving the cutting knife to move up and down is the prior art and has no direct relevance to the present technical solution, so it will not be described in detail.
[0029] Two rows of transmission wheels 13 are rotatably connected inside the base body 11, and the transmission wheels 13 are embedded in the base body 11 so that the base body 11 can serve as an auxiliary limiter from both sides of the transmission wheels 13; the outer side of the base body 11 is fixedly connected to the motor housing of the motor 14, and the single row of transmission wheels 13 are connected by belt transmission.
[0030] In one case of this embodiment, two rows of transmission wheels 13 are driven by corresponding motors respectively. Specifically, the output shaft of the motor is fixed to the rotation center of a certain transmission wheel 13 in the corresponding row of transmission wheels 13 .
[0031] Another situation of this embodiment: the two rows of transmission wheels 13 are driven by the same motor. Specifically, the output shaft of the motor is fixedly connected to any one of the transmission wheels 13. In the two rows of transmission wheels 13, two corresponding transmission wheels 13 are fixedly connected by a connecting rod, so that the two corresponding transmission wheels 13 can rotate synchronously, which is not shown in the figure.
[0032] The cover plate 2 includes a plate body 21 and a pressing block 22, and the pressing block 22 is fixed on the plate body 21. When the connecting body 12 is covered on the base body 11, the position of the pressing block 22 is located directly above the corresponding single-row transmission wheel 13, and the distance between the pressing block 22 and the transmission wheel 13 is smaller than the diameter of the clamped rubber carcass. Through the above arrangement, after the plate body 21 is closed on the base body 11, the rubber carcass located on the transmission wheel 13 is in a compressed state. Because of the limiting of the base body 11 and the transmission of the transmission wheel 13, the rubber carcass in the compressed state can be continuously transported to the side of the connecting body 12, so that the cutting knife can cut the fed rubber carcass.
[0033] Preferably, the distance between the pressing block 22 and the conveying wheel 13 is 40%-70% of the diameter of the clamped rubber carcass, so that the rubber carcass is in a clamped state but can still move under the conveying action of the conveying wheel 13.
[0034] Furthermore, the plate body 21 and the seat body 11 are detachably connected by a screw 23 .
[0035] Furthermore, a support member 3 is placed between the plate body 21 and the base body 11, and the support member 3 includes an elastic telescopic rod 31 and an elastic clamp 32. Placement grooves are provided on the opposite surfaces of the plate body 21 and the base body 11, and the placement grooves and the two ends of the elastic telescopic rod 31 are snap-connected. The elastic telescopic rod 31 includes two segments, and the two segments are elastically slidably connected by springs. A clamping groove is retained between the two segments, and the elastic clamp 32 can be inserted into the clamping groove under the action of elastic force to limit the length of the two segments after being pressed together.
[0036] In simple terms, the more the elastic clamps 32 are clamped, the smaller the elastic telescopic rod 31 can be retracted.
[0037] The support member 3 is used in conjunction with the screw rod 23 to adjust the distance between the plate body 21 and the seat body 11 .
[0038] Example 2
[0039] like Figure 1-Figure 5 On the basis of the above embodiment, a tail cutting piece 4 is provided on the base 1, and the tail cutting piece 4 includes a drawer 41, a rotating shaft 42, a tail cutting knife 43 and a nut 44. According to the layout of the motor 14 and the transmission wheel 13 in the embodiment, without interfering with other components, a slide groove is opened in the base 1, and the drawer 41 is slidably connected in the slide groove in a pull-out manner. The rotating shaft 42 passes through and is rotatably connected to the drawer 41. The nut 44 located on the outside of the drawer 41 is respectively threadedly connected to the two ends of the rotating shaft 42, and the tail cutting knife 43 is fixedly connected to the rotating shaft 42. When necessary, the nut 44 can be screwed to lock the rotating shaft 42 and fix the position of the tail cutting knife 43.
[0040] The drawer 41 where the nut 44 is located is recessed inwardly, and the nut 44 is placed in the recess to be embedded in the side wall of the drawer 41, thereby reducing the probability of interference between the nut 44 and the side wall of the slide when the drawer 41 is stored in the slide.
[0041] Furthermore, a pin hole 45 is formed through the drawer 41 , and a pin shaft 46 can be inserted into the pin hole 45 . The blocking effect of the pin shaft 46 can stably restrict the drawer 41 to the outside of the base body 11 .
[0042] Based on the above structure: when in use, first insert the pin shaft 46 into the appropriate pin hole 45, adjust and limit the position of the drawer 41, then place the rubber carcass between the base 1 and the cover 2, close the base 1 and the cover 2, and when the rubber carcass at the end contacts the upright tail cutting knife 43, the rubber is transmitted by the transmission wheel 13 on the one hand, and cut by the tail cutting knife 43 on the other hand. At this time, the user does not need to perform additional operations, and the tail cutting knife 43 can cut the carcass, completely dividing the carcass at the end into two halves, thereby reducing the traction interference of the carcass segments connected together at the end on the carcass segments located on the two rows of transmission wheels 13.
[0043] In summary, the working principle of the utility model can be briefly described as follows: the tire body is placed on the transmission wheel 13, and the seat body 11 and the pressure block 22 are used to limit the tire body on the transmission wheel 13 to reduce the probability of the tire body twisting; and the tail cutting piece 4 is used to cut the end of the moving tire body, and the tire body originally connected together is completely divided into two, which not only improves the efficiency, but also reduces the interference of the end of the tire body with the front end.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
