Description

Technical Field

[0001] The invention relates to the technical field of waste tire recycling, in particular to a tire processing system. 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, and then classifying and recycling them. The final recycled products mainly include rubber, steel wire and fiber embedded in the rubber, etc. 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.

[0004] In order to cut waste tires into pieces for processing, the waste tire processing equipment previously applied by the applicant provides an implementation scheme, which realizes tearing the tires into small pieces through an interlocking dual-axis machine. 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 batches. Therefore, developing a waste tire processing system that can better meet various needs will be more conducive to more flexible and efficient recycling of waste tires. Summary of the invention

[0073] 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.

[0074] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "horizontal", "vertical", "top", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0075] 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 it can be internally connected between 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.

[0076] Implementation method:

[0077] See also Figure 1-26 The present invention shows a tire processing system, including a tire slitting machine, a tire stripping machine and a tire block cutting machine, wherein the tire slitting machine is used to divide the tire into tire beads, the tire stripping machine is used to cut the tire beads into tire strips, and the tire block cutting machine is used to cut the tire strips into tire blocks. That is, it can be understood that the tire is cut into tire beads by the tire slitting machine, and then the tire bead is cut into long strips by the tire stripping machine, and finally the long strips are cut into small block-shaped tire blocks by the tire block cutting machine, thereby realizing the cutting, stripping and block cutting of the tire, and then realizing more flexible and efficient recycling of waste tires.

[0078] Specifically, see Figure 1-9The tire slitting machine includes a frame 10, a pushing mechanism 108 and a cutting mechanism. A tire placement platform 101 is provided on the frame 10 for placing a tire 110 to be cut. The tire placement platform 101 is provided with a tire inlet 102 and a tire outlet 103. The tire 110 is placed flat at the tire inlet 102 and pushed into the tire placement platform 101; the pushing mechanism 108 is used to push the tire 110 to be cut into a tire 110 cutting position; the cutting mechanism is used to cut the pushed tire 110 into tire rims.

[0079] The cutting mechanism includes a fixed knife mechanism 105 and a movable knife mechanism 107, and the fixed knife mechanism 105 and the tire placement platform 101 can move relative to each other, so that the fixed knife mechanism 105 can extend into or out of the interior of the tire 110. It can be understood by those skilled in the art that the fixed knife mechanism 105 and the tire placement platform 101 can move relative to each other, that is, when the tire placement platform 101 is stationary, the fixed knife mechanism 105 can be raised and lowered, or, when the fixed knife mechanism 105 is stationary, the placement platform can be raised and lowered.

[0080] The movable knife mechanism 107 includes a cutting blade 1071 for radially cutting the tire 110, a first driving mechanism 1076 and a second driving mechanism 1077. The cutting blade 1071 can be driven by the first driving mechanism 1076 to move toward the direction close to the tire 110, so that the cutting blade 1071 and the fixed knife mechanism 105 can press the tire 110 against each other. The cutting blade 1071 can be driven by the second driving mechanism 1077 to rotate to cut the tread of the tire 110.

[0081] Specifically, the moving knife mechanism 107 of this embodiment further includes a moving knife bracket 1073, a swing arm assembly, and a moving knife shaft 1072. The cutting blade 1071 is arranged on the moving knife shaft 1072. The second driving mechanism 1077 is used to drive the moving knife shaft 1072 to rotate. One end of the swing arm assembly is installed on the moving knife shaft 1072, and the other end of the swing arm assembly is pivotally connected to the moving knife bracket 1073. The first driving mechanism 1076 is used to drive the swing arm assembly to swing. The first driving mechanism 1076 is a rotating cylinder, and the second driving mechanism 1077 is a motor. Preferably, the above-mentioned swing arm assembly includes a swing shaft 1078, a first swing arm 1074 and a second swing arm 1075, the swing shaft 1078 is vertically arranged on the movable knife bracket 1073, one end of the first swing arm 1074 is pivoted to the swing shaft 1078, the other end of the first swing arm 1074 is connected to the movable knife shaft 1072, one end of the second swing arm 1075 is connected to the first swing arm 1074, the other end of the second swing arm 1075 is connected to the movable shaft 11102, and the second driving mechanism 1077 is connected to the second swing arm 1075.

[0082] Based on the above structure, when the tire 110 needs to be cut, the first drive mechanism 1076 first drives the second swing arm 1075 to swing, and then the second swing arm 1075 drives the first swing arm 1074 to swing, thereby driving the movable knife shaft 1072 to swing, so that the cutting blade 1071 moves in the direction close to the tire 110. When the cutting blade 1071 abuts against the outer wall of the tire 110, the second drive mechanism 1077 drives the movable knife shaft 1072 to rotate, and then the cutting blade 1071 rotates, so that the cutting blade 1071 radially cuts the tire 110, and at the same time, the tire 110 rotates in the opposite direction of the cutting direction of the cutting blade 1071 under the driving force of the cutting blade 1071, thereby completing the rapid cutting of the tire 110 and cutting the tire 110 into two parts. The movable knife mechanism 107 of the present invention has a simple structure, high cutting efficiency, and does not require an additional driving device to drive the tire 110 to rotate, which is conducive to saving energy consumption and reducing costs. More specifically, the first swing arm 1074 and the second swing arm 1075 are in an arc-shaped structure. By setting the first swing arm 1074 and the second swing arm 1075 to an arc-shaped structure, on the one hand, space can be saved, and on the other hand, it can guide the movement of the cutting tool and accurately control the movement direction of the cutting blade 1071.

[0083] Preferably, the fixed knife mechanism 105 includes a fixed knife shaft 1051, an upper rotating wheel 1052 and a lower rotating wheel 1053 installed on the fixed knife shaft 1051, the upper rotating wheel 1052 and the lower rotating wheel 1053 can rotate along the inner tread of the tire 110, and a gap 1056 is provided between the upper rotating wheel 1052 and the lower rotating wheel 1053 for inserting the cutting blade 1071. In the above structure, the fixed knife mechanism 105 is first inserted into the center hole 1101 of the tire 110 (the fixed knife mechanism 105 can be lifted up and down to achieve the fixed knife mechanism 105 being inserted into the center hole 1101 of the tire 110; the fixed knife mechanism 105 can also be lifted up and down by placing a platform to achieve the fixed knife mechanism 105 being inserted into the center hole 1101 of the tire 110), and then the cutting blade 1071 is first driven by the first driving mechanism 1076 to move toward the tire 110 to push the tire 110 closer to the fixed knife mechanism 105, so that the upper rotating wheel 1052 and the lower rotating wheel 1053 can be moved. The cutting blade 1071 and the fixed blade mechanism 105 finally press the tire 110 against each other to position the tire 110, and then the cutting blade 1071 cuts the tire 110. When cutting, the cutting blade 1071 can pass through the gap 1056 between the upper rotating wheel 1052 and the lower rotating wheel 1053. Since the gap 1056 is provided, the cutting blade 1071 is prevented from directly contacting the upper rotating wheel 1052 and the lower rotating wheel 1053, so that the cutting blade 1071 can cut the tire 110 more thoroughly.

[0084] Specifically, the outer surfaces of the upper rotating wheel 1052 and the lower rotating wheel 1053 of this embodiment are both provided with protrusions. In this way, the friction between the upper rotating wheel 1052, the lower rotating wheel 1053 and the inner surface of the tire 110 can be increased, so that the positioning effect of the fixed knife mechanism 105 is better. Preferably, the upper rotating wheel 1052 is detachably mounted with an upper fixed knife 1054, and the lower rotating wheel 1053 is detachably mounted with a lower fixed knife 1055. The upper fixed knife 1054 and the lower fixed knife 1055 are arranged opposite to each other, and the gap 1056 is located between the upper fixed knife 1054 and the lower fixed knife 1055. When the cutting blade 1071 is inserted into the gap 1056, the upper fixed knife 1054 and the lower fixed knife 1055 both rotate, which plays a guiding role in the rotation of the tire 110. In addition, the upper fixed knife 1054 and the lower fixed knife 1055 will wear out to a certain extent as the number of cutting increases. Since the upper fixed knife 1054 and the lower fixed knife 1055 are detachably mounted on the upper rotating wheel 1052 and the lower rotating wheel 1053, respectively, they can be replaced at any time. By mounting the upper fixed knife 1054 and the lower fixed knife 1055 on the upper rotating wheel 1052 and the lower rotating wheel 1053, the upper rotating wheel 1052 and the lower rotating wheel 1053 are prevented from being worn out.

[0085] In a preferred embodiment, the tire 110 is cut by fixing the placement platform and lifting the fixed knife mechanism 105 up and down. Before cutting, the tire 110 is first pushed into the tire 110 placement platform from the tire inlet 102 in a flat position, and the center hole 1101 of the tire 110 is aligned with the fixed knife mechanism 105. Then the fixed knife mechanism 105 extends into the center hole 1101 of the tire 110. The cutting blade 1071 first moves toward the tire 110 under the drive of the first driving mechanism 1076 to push the tire 110 closer to the fixed knife mechanism 105, so that the fixed knife mechanism 105 can be against the inner surface of the tire 110. Finally, the cutting blade 1071 and the fixed knife mechanism 105 press the tire 110 against each other, and then the second driving mechanism 1077 drives the cutting blade 1071 to move toward the tire 110. The blade 1071 rotates to cut the tread of the tire 110. At the same time, the tire 110 rotates in the opposite direction of the cutting direction of the cutting blade 1071 under the cutting bite force of the cutting blade 1071, and finally the tire 110 is divided into two parts, an upper part and a lower part. After the cutting is completed, the moving knife mechanism 107 is reset, and the pushing mechanism 108 pushes the tire 110, so that the fixed knife mechanism 105 is in the center hole 1101 in the tire 110, so that the fixed knife mechanism 105 is convenient to move out of the tire 110, so that the cut tire 110 can be moved out of the tire placement platform 101 from the tire outlet 103, so as to perform the next step of processing on the tire 110.

[0086] Preferably, this embodiment shows a specific implementation method of the above-mentioned fixed knife mechanism 105 extending into or out of the center hole 1101 of the tire 110. The tire 110 slitting machine also includes a guide mechanism 106, and the guide mechanism 106 includes a mounting seat 1061, a guide block 1062, a guide rail assembly and a third driving mechanism 1065 connected to the guide block 1062. The fixed knife shaft 1051 is arranged on the mounting seat 1061, and the mounting seat 1061 is arranged on the guide block 1062. The guide block 1062 is slidably matched with the guide rail assembly, and the first driving mechanism 1076 is used to drive the guide block 1062 to move up and down, thereby realizing that the fixed knife mechanism 105 extends into or out of the center hole 1101 of the tire 110. It should be noted that, since the fixed knife mechanism 105 is still located in the inner ring of the tire 110 after cutting is completed, the pushing mechanism 108 is required to push the tire 110 so that the fixed knife mechanism 105 is in the center hole 1101 of the tire 110, and the fixed knife mechanism 105 can be separated from the center hole 1101 of the tire 110.

[0087] Preferably, the guide rail assembly comprises a first guide rail 1063 and a second guide rail 1064, the first guide rail 1063 being provided with a square guide groove 10631, the second guide rail 1064 being provided with a V-shaped guide groove 10641 or a trapezoidal guide groove, the square guide groove 10631 and the V-shaped guide groove 10641 or the trapezoidal guide groove being arranged opposite to each other, the first surface of the guide block 1062 being provided with a first guide strip 10621 matching the square guide groove 10631, the second surface of the guide block 1062 opposite to the first surface being provided with a second guide strip 10622 matching the V-shaped guide groove 10641 or the trapezoidal guide groove. That is, it can be understood that the second guide bar 10622 of the guide block 1062 cooperates with the second guide rail 1064 having a V-shaped guide groove 10641 or a trapezoidal guide groove, and the second guide bar 10622 and the second guide rail 1064 are abutted against each other through the inclined surfaces, which can significantly reduce the gap between the guide block 1062 and the second guide rail 1064, making the connection between the guide block 1062 and the second guide rail 1064 tighter and firmer, ensuring that the guide block 1062 can work stably, and improving the service life of the guide block 1062.

[0088] Of course, the cutting of the tire 110 can also be achieved by fixing the fixed knife mechanism 105 of the above structure and lifting the placement platform up and down. The tire slitting machine also includes a lifting mechanism 111 for driving the placement platform to lift up and down; the lifting mechanism 111 includes two lifting structures 1110 arranged on both sides of the bottom of the placement platform, a linkage structure 1111 for making the two lifting structures 1110 move synchronously, and a lifting cylinder 1112 for driving the lifting structure 1110; the lifting structure 1110 includes two bearing seats 11101 arranged on the frame 10, a moving shaft 11102 rotatably arranged between the two bearing seats 11101, and a swinging member 11103, one end of the swinging member 11103 is fixed to the moving shaft 11102, and the other end is provided with a sliding wheel that can slide along the bottom frame of the placement platform; the linkage structure 111 1 comprises two rotating pairs 11110 respectively fixed on the moving shafts 11102 of the two lifting structures 1110 and connecting rods 11111 respectively hinged to the rotating pairs 11110 at both ends; one end of the lifting cylinder 1112 is hinged to the frame 10, and the other end is connected to any one of the moving shafts 11102 through a connecting member 1113; one end of the connecting member 1113 is fixed to the moving shaft 11102, and the other end is hinged to the push rod of the lifting cylinder 1112; the push rod of the lifting cylinder 1112 pushes the connecting member 1113, drives the moving shaft 11102 to rotate and drives the linkage structure 1111 to rotate the moving shaft 11102 of the other lifting structure 1110 to realize the swinging member 11103 swinging upward to support the placement platform.That is, before cutting, the tire 110 is first pushed into the tire 110 placement platform from the tire entrance 102 in a flat position, and the center hole 1101 of the tire 110 is aligned with the fixed knife mechanism 105, and then the tire 110 on the placement platform is lifted to a specified height by the lifting mechanism 111 (the specified position enables the fixed knife mechanism 105 to enter the center hole 1101 of the tire 110), that is, at this time, the fixed knife mechanism 105 is located in the center hole 1101 of the tire 110, and then the cutting blade 1071 is driven by the first driving mechanism 1076 to move toward the direction of the tire 110 to push the tire 110 close to the fixed knife mechanism 105, so that the fixed knife mechanism 105 can abut against the inner tread of the tire 110, and finally the cutting blade 1071 and the fixed knife mechanism 105 are aligned. The knife mechanism 105 presses the tires 110 against each other, and then the second driving mechanism 1077 drives the cutting blade 1071 to rotate to cut the tread of the tire 110. At the same time, the tire 110 rotates in the opposite direction of the cutting direction of the cutting blade 1071 under the cutting bite force of the cutting blade 1071, and finally the tire 110 is divided into two parts, the upper and lower parts. After the cutting is completed, the moving knife mechanism 107 is reset, and the pushing mechanism 108 pushes the tire 110, so that the fixed knife mechanism 105 is in the center hole 1101 in the tire 110, so that the fixed knife mechanism 105 is convenient to move out of the tire 110, so that the cut tire 110 can be moved out of the tire placement platform 101 from the tire outlet 103, so as to perform the next step of processing on the tire 110.

[0089] Preferably, the pushing mechanism 108 includes a guide member 1081 arranged along the moving direction of the tire 110, a slider 1082 slidably matched with the guide member 1081, a wing 1083 rotatable around the central axis of the slider 1082, a rotating structure for rotating the wing 1083, and a fourth driving mechanism 1087 for driving the slider 1082 to move along the guide member 1081, and the guide member 1081 is provided with a mounting portion for mounting and fixing the guide member 1081, and one end of the wing 1083 is rotatable with the slider 1082. 082 is rotatably connected, and the other end is a free end. The rotating structure includes a pulley 1084 arranged on the wing 1083 and an auxiliary member 1085 arranged at the bottom of the wing 1083. The auxiliary member 1085 is provided with a first inclined surface 10851 inclined from the side to the middle corresponding to the sliding direction of the pulley 1084, and the top of the auxiliary member 1085 is also provided with a second inclined surface 10852 inclined from top to bottom. When the pulley 1084 slides backward along the first inclined surface 10851, the free end of the wing 1083 rotates upward accordingly. It should be noted that the pushing mechanism 108 is not limited to Figure 2 The structure in can also be Figure 6The structure in the embodiment can realize pushing of the tire 110 by using a double guide rod cylinder and a telescopic plate fixedly connected to the telescopic rod end of the double guide rod cylinder.

[0090] When the wing 1083 in this embodiment rotates and folds upward, the pulley 1084 is attached to the highest point of the first inclined surface 10851 of the auxiliary component 1085. At the same time, the pulley 1084 is farthest from the fixing point of the wing 1083 and the slider 1082. When the fourth driving mechanism 1087 pushes the slider 1082 to slide forward along the guide member 1081, the slider 1082 moves forward relative to the auxiliary component 1085, and the wing 1083 rotates downward due to its own weight, driving the pulley 1084 to gradually slide forward and downward along the first inclined surface 10851. When the pulley 1084 slides away from the first inclined surface 10851 and the slider 1082 and the wing 1083 are away from the auxiliary component 1085, the wing 1083 is in a fully opened state, and the free end of the wing 1083 can directly contact the tire 110. The fourth driving mechanism 1087 continues to push the slider 1082 together with the wing 1083, thereby pushing the tire 110 forward. When the pulley 1084 slides backward along the first inclined surface 10851, the pulley 1084 on the wing 1083 gradually moves backward and contacts the auxiliary part 1085, and then passes along the first inclined surface 10851 of the auxiliary part 1085. Since the fixing place of the pulley 1084, the wing 1083 and the slider 1082 gradually becomes larger, the pulley 1084 moves upward and backward, and the wing 1083 also folds upward. When the pulley 1084 slides to the highest point on the first inclined surface 10851 of the auxiliary part 1085, the wing 1083 is in a fully folded state. At this time, the tire 110 can be pushed into the tire 110 placement table from below the tire inlet 102 without affecting the feeding.

[0091] Preferably, in this embodiment, in order to prevent the wing 1083 from rotating due to its own weight and automatically rotating to the bottom to a folded state without limit, the effect of pushing the tire 110 is not good at this time, and the wing 1083 cannot be automatically folded upward without external force through the auxiliary member 1085 in the downward folded state, which will affect the transportation of the next tire 110. For this, the wing 1083 is also provided with a self-locking structure for limiting the rotation angle. There are multiple implementation methods of the self-locking structure in this scheme: First, the self-locking structure includes a protrusion arranged on the outer side wall of the slider 1082 and a guide groove arranged at the connection between the wing 1083 and the slider 1082, and the groove surface of the protrusion and the guide groove abuts against each other to limit the wing 1083 from continuing to rotate along the original rotation direction. Second, the wing 1083 is provided with two pieces, and the two wings 1083 are respectively located on both sides of the auxiliary component 1085. The self-locking mechanism includes a protrusion 1086 arranged at the connection between the wing 1083 and the slider 1082. During the rotation process, the two wings 1083 are abutted against each other by the two protrusions 1086 to limit the two wings 1083 from continuing to rotate along the original rotation direction.

[0092] The above-mentioned multiple self-locking methods can ensure that the wing 1083 will be locked when it rotates to a specified position or angle, and the wing 1083 will not continue to rotate along the rotation direction, and the contact part of the wing 1083 can contact the tire 110. At the same time, when the fourth driving mechanism 1087 drives the slider 1082 to move backward, the wing 1083 can change from a flat state to a folded state.

[0093] Preferably, the fixing portion is bent backward in a Z shape so that the contact portion and the connection between the wing 1083 and the slider 1082 are not in the same straight line. At this time, the contact portion is parallel to the connection between the wing 1083 and the slider 1082, and the contact portion is located behind the connection between the wing 1083 and the slider 1082. When the tire 110 is placed slightly behind the wing 1083, the wing 1083 is in a horizontal state after being unfolded, and the contact portion is relatively behind the connection between the wing 1083 and the slider 1082, and can still contact the tire 110 during the forward pushing process, thereby increasing the compatibility of the wing 1083 in pushing the tire 110.

[0094] Through the above arrangement, the present solution can realize the up and down movement and opening and closing movement of the wing 1083 without power, and the free end of the wing 1083 can be completely moved up and down by its own gravity to achieve the effect of pushing the tire 110. The structure is simple and reliable, and energy is saved. In addition, the fourth driving mechanism 1087 can be realized by a motor or a hydraulic cylinder or a cylinder.

[0095] Based on the above structure, after the tire 110 is pushed into the tire placement platform 101, the center hole 1101 of the tire 110 is aligned with the fixed knife mechanism 105, wherein the fixed knife mechanism 105 is located above the tire 110 placement platform, and then the third driving mechanism 1065 drives the guide block 1062 to move downward along the track of the guide rail assembly, and then drives the fixed knife mechanism 105 to extend into the center hole 1101 of the tire 110, and then the first driving mechanism 1076 drives the cutting blade 1071 to approach the direction of the tire 110, and then pushes the tire 110 to move, so that the fixed knife mechanism 105 can be against the inner tread of the tire 110. After the cutting is completed, the pushing mechanism 108 first pushes the tire 110 so that the fixed knife mechanism 105 is located at the center hole 1101 of the tire 110, and then the third driving mechanism 1065 drives the fixed knife mechanism 105 to move upward to reset the fixed knife mechanism 105, so that the cut tire 110 can be pushed out of the tire placement platform 101 from the tire outlet 103. Among them, the third driving mechanism 1065 of this embodiment can be a driving component such as a cylinder, a motor or an oil cylinder. In this embodiment, by setting the guide mechanism 106, the fixed knife mechanism 105 can automatically extend into or out of the center hole 1101 of the tire 110, thereby facilitating the cutting and positioning of the tire 110.

[0096] On the basis of the above structure, after the cutting is completed, in order to enable the fixed knife mechanism 105 to be separated from the tire 110, the fixed knife mechanism 105 needs to be located at the position of the center hole 1101 of the tire 110. In this embodiment, the tire 110 is moved by the pushing mechanism 108, and the specific process is: the fourth driving mechanism 1087 drives the slider 1082 to move along the guide member 1081 toward the moving knife mechanism 107, so that the wing 1083 can contact the tire 110, and then the wing 1083 pushes the tire 110 to move in the direction of the moving knife mechanism 107, so that the fixed knife mechanism 105 is located at the position of the center hole 1101 of the tire 110, and then the third driving mechanism 1065 drives the fixed knife mechanism 105 to reset.

[0097] Of course, the tire 110 cutting machine also includes a push mechanism 109, and the push mechanism 109 includes a push plate 1091 and a fifth driving mechanism 1092. The push plate 1091 can push the tire 110 under the drive of the fifth driving mechanism 1092 so that the tire 110 is pushed out from the tire outlet 103. After the cutting is completed, the push plate 1091 pushes the tire 110 to move in the direction of the tire outlet 103 under the drive of the fifth driving mechanism 1092, and then pushes the cut tire 110 out of the tire 110 placement table. In addition, in order to make the push plate 1091 better push the tire 110, the push plate 1091 of this embodiment is designed as an arc structure to fit the outer contour of the tire 110, so that the push plate 1091 can stably push the tire 110 to move. In addition, the fifth driving mechanism 1092 of this embodiment can adopt a driving mechanism such as a cylinder, a motor or an oil cylinder.

[0098] Preferably, a circular hole is provided on the tire placement platform 101, and a universal bull's eye bearing 104 is installed in the circular hole. By installing the universal bull's eye bearing 104 on the tire placement platform 101, the tire 110 and the tire placement platform 101 have less friction, and the tire 110 is easier to push into the cutting station of the tire placement platform 101, and is also easier to push out of the tire placement platform 101. Of course, there are many ways to reduce the friction between the tire 110 placement platform and the tire 110, and the universal bull's eye bearing 104 is only one of them.

[0099] In summary, the tire slitting machine achieves the positioning of the tire cutting through the mutual cooperation of the fixed knife mechanism 105 and the moving knife mechanism 107, avoids the tire 110 from moving randomly during cutting, and effectively improves the cutting efficiency; by setting the moving knife mechanism, the tire is automatically cut, and the tire 110 is cut into tire rims, which reduces labor intensity and improves cutting efficiency.

[0100] In this preferred embodiment, see Figure 10-14The tire strip cutting machine includes a fixed frame 20, a cutter assembly 30, a circular cutter disc driving mechanism 33, a material receiving frame 34 and a material receiving frame driving mechanism 36. Specifically, the cutter assembly 30 includes a first circular cutter disc 31 and a second circular cutter disc 32 pivotally connected to the fixed frame 20 respectively; the first circular cutter disc 31 and the second circular cutter disc 32 are arranged in an upper and lower position, and the blades of the first circular cutter disc 31 and the second circular cutter disc 32 intersect and fit each other. In a preferred embodiment, a pressing mechanism can be provided, and the pressing mechanism can be connected to the first circular cutter disc 31 or the second circular cutter disc 32, so as to drive the first circular cutter disc 31 and the second circular cutter disc 32 to fit closely. In one embodiment, the pressing mechanism is coaxially arranged with the first circular cutter disc 31 and drives the first circular cutter disc 31 to press closely on the second circular cutter disc 32. The pressing mechanism can adopt any structure that can achieve the above-mentioned function, which is not limited here, such as being implemented by a compression spring or by magnetic force. The material receiving frame 34 is provided with a material receiving post 35; the material receiving post 35 is used for matching the tire bead, and the tire bead can rotate around the material receiving post 35 under the driving of other forces. In a preferred embodiment, the material receiving post 35 can rotate relative to the material receiving frame 34 around the central axis of the material receiving post 35, so that the material receiving post 35 and the tire bead can rotate synchronously or approximately synchronously, thereby reducing the sliding friction between the material receiving post 35 and the tire bead, thereby reducing the wear of the material receiving post 35.

[0101] The receiving rack 34 is installed on the fixed frame 20 and can rotate around the horizontal axis relative to the fixed frame 20; the receiving rack 34 is used to transport the tire bead placed on the receiving column 35 to the cutter assembly 30, so that the cutter assembly 30 completes the cutting of the tire bead and cuts the tire bead into a long tire strip. Therefore, the receiving rack 34 can rotate around the rotating shaft on the fixed frame 20 within a certain range. That is, it can be set to a loading position and a cutting position. Under the drive of the receiving drive device, the receiving rack 34 rotates between the loading position and the cutting position around the rotating shaft set on the fixed frame 20. The loading position can be a position where the central axis of the receiving column 35 is perpendicular to the circular blade surface of the first circular blade disc 31, or it can be a position between the position where the central axis of the receiving column 35 is perpendicular to the circular blade surface of the first circular blade disc 31 and the cutting position. The loading position satisfies that when the tire bead is placed on the receiving column 35, the outer tread of the tire bead will not touch the cutter assembly 30, and the tire bead will not fall off the receiving column 35. The outer tread of the bead is cut at a cutting position such that the first circular cutter disc 31 and the second circular cutter disc 32 of the cutting assembly are engaged with the bead and the bead is cut into strips.

[0102] In addition, the circular cutter disc driving mechanism 33 is used to drive the first circular cutter disc 31 and the second circular cutter disc 32 to rotate, and the first circular cutter disc 31 and the second circular cutter disc 32 rotate in opposite directions. Fig.14As shown, the first circular cutter disc 31 rotates clockwise, and the second circular cutter disc 32 rotates counterclockwise, so that the cutting directions of the first circular cutter disc 31 and the second circular cutter disc 32 are the same, both of which are as shown in FIG. Fig.14 The direction indicated by arrow G can be used to cut the tire; the material receiving rack driving mechanism 36 is used to drive the material receiving rack 34 to rotate.

[0103] On the basis of the above structure, the receiving rack driving mechanism 36 drives the receiving rack 34 to rotate until the receiving column 35 is in the loading position. At this time, the bead of half of the tire can be mounted on the receiving column 35, and the side of the tire without the bead is facing upward. The receiving rack driving mechanism 36 drives the receiving rack 34 to rotate in a horizontal state in conjunction with the receiving column 35. During this process, the tire on the receiving column 35 is gradually approaching the first circular cutter disc 31 and the second circular cutter disc 32 on the fixed frame 20. In this way, the outermost part of the tire can enter between the blades of the first circular cutter disc 31 and the second circular cutter disc 32 during the rotation process. The circular cutter disc driving mechanism 33 drives the first circular cutter disc 31 and the second circular cutter disc 32 to rotate in opposite directions. During the rotation process, the first circular cutter disc 31 and the second circular cutter disc 32 can start cutting from the outermost circumference of the tire. At this time, the first circular cutter disc 31 and the second circular cutter disc 32 cooperate to bite the tire during the cutting process to drive the tire to rotate in conjunction with the receiving column 35 relative to the receiving rack 34, or an external force is used to drive the tire. The receiving column 35 rotates relative to the receiving frame 34, so that the other parts of the outer circumference of the tire are continuously conveyed between the blades of the first circular knife disc 31 and the second circular knife disc 32, so as to achieve a full circle cutting of the outermost circumference of the tire, and as the receiving column 35 continuously rotates closer to the fixed frame 20, the tire is gradually squeezed between the first circular knife disc 31 and the second circular knife disc 32. When the receiving column 35 is completely horizontal, the tire is cut, that is, the tire stripping operation is completed. In this way, the tire stripping operation can be achieved in conjunction with the mobile operation to reduce manual work.

[0104] Furthermore, the material receiving column 35 includes a bottom plate 350 and a cylinder 351 fixed on the bottom plate 350. Specifically, when the material receiving column 35 is in a vertical state, the cylinder 351 is located above the bottom plate 350; the cylinder 351 is used for matching the tire bead; the bottom plate 350 has a collision portion extending out of the outer surface of the cylinder 351. It should be noted here that the outer surface of the cylinder 351 refers to the curved surface of the cylinder 351 facing the outside; the collision portion is used to abut against the tire to prevent the tire from being separated from the cylinder 351 when the tire is mounted outside the cylinder 351. Furthermore, the cross section of the bottom plate 350 is circular; the bottom plate 350 is coaxially arranged with the cylinder 351, and the diameter of the bottom plate 350 is greater than the outer diameter of the cylinder 351, so that the bottom plate 350 has a portion uniformly extending out of the outer periphery of the cylinder 351, which is the collision portion, to achieve full collision with the tire.

[0105] Preferably, the material receiving rack driving mechanism 36 can be implemented by a cylinder. Specifically, the cylinder body of the cylinder is hinged on the fixed frame 20, and the telescopic rod of the cylinder is hinged on the material receiving rack 34; of course, the above-mentioned material receiving rack driving mechanism 36 can also adopt a rotating motor, and the output shaft of the rotating motor is transmission-connected to the material receiving rack 34, and the central axis of the output shaft of the rotating motor coincides with the pivot axis of the material receiving rack 34.

[0106] The above-mentioned circular cutter disc drive mechanism 33 can be implemented in the following manner: the circular cutter disc drive mechanism 33 includes a rotating motor, a driving gear fixedly connected to the first circular cutter disc 31, and a passive gear fixedly connected to the second circular cutter disc 32. Specifically, the output shaft of the rotating motor is transmission-connected to the first circular cutter disc 31, and the driving gear and the passive gear are meshed. However, the driving gear and the passive gear are vulnerable parts and are easily damaged. The circular cutter disc drive mechanism 33 may also preferably be implemented as follows: the circular cutter disc drive mechanism 33 comprises a first rotary motor 330 and a second rotary motor 331; the body of the first rotary motor 330 is mounted on the fixed frame 20, and the output shaft of the first rotary motor 330 is connected to the first circular cutter disc 31 in a transmission manner; the body of the second rotary motor 331 is mounted on the fixed frame 20, and the output shaft of the second rotary motor 331 is connected to the second circular cutter disc 32 in a transmission manner. At this time, by controlling the rotation direction of the rotation shafts of the first rotary motor 330 and the second rotary motor 331, the rotation direction of the first circular cutter disc 31 and the second circular cutter disc 32 can be controlled; here, by using the first rotary motor 330 and the second rotary motor 331 to drive separately, there is no problem of damage to wearing parts such as gears; on the other hand, under the condition of equal energy consumption, since the first rotary motor 330 and the second rotary motor 331 are used to drive separately, the energy loss generated by the intermediate driving gear and the passive gear during the transmission process can be omitted, and the driving force of the first rotary motor 330 and the second rotary motor 331 to drive separately is greater and the energy loss is smaller.

[0107] Preferably, the tire strip cutting machine further comprises a toggle gear 37; the toggle gear 37 is rotatably mounted on the fixing frame 20 around its central axis; when the toggle gear 37 rotates, the tooth portion of the toggle gear 37 can toggle the tire on the receiving column 35 so that the tire rotates around the central axis of the receiving column 35 relative to the first circular cutter disc 31 and the second circular cutter disc 32; the circular cutter disc driving mechanism 33 is also used to drive the toggle gear 37 when driving the first circular cutter disc 31 and the second circular cutter disc 32 to rotate. 37 rotates; in this way, part of the tire enters between the first circular blade disc 31 and the second circular blade disc 32. During the cutting process of the cutter assembly 30, the toggle gear 37 toggles the tire to rotate. During the rotation of the tire, the first circular blade disc 31 and the second circular blade disc 32 cooperate to cut the circumference of the tire. At this time, the toggle gear 37 can replace manpower, or, on the basis of the first circular blade disc 31 and the second circular blade disc 32 cooperating to bite the tire, further ensure that the tire continues to rotate circumferentially relative to the cutter assembly 30, that is, ensure the circumferential cutting of the gear. Furthermore, the toggle gear 37 is fixedly connected to the second circular blade disc 32 and is coaxially arranged. In this way, when the circular blade disc driving mechanism 33 drives the second circular blade disc 32, the toggle gear 37 can be rotated. It is worth mentioning that the tooth portion of the toggle gear 37 extends along the rotation direction of the second circular blade disc 32, further ensuring the toggle of the tire.

[0108] In order to realize the transmission connection between the first circular cutter disc 31 and the circular cutter disc driving mechanism 33, here, the first circular cutter disc 31 includes a cutter disc body 311, a blade disc body 312 and a locking structure 313; the locking structure 313 is used to fix the cutter disc body 311 and the blade disc body 312 in connection; the blade disc body 312 is coaxially arranged with the cutter disc body 311, and the blade of the blade disc body 312 protrudes out of the cutter disc body 311; the circular cutter disc driving mechanism 33 is transmission-connected with the cutter disc body 311, so that the strength of the blade disc body 312 can be enhanced through the cutter disc body 311, and the direct connection between the blade disc body 312 and the circular cutter disc driving mechanism 33 to damage the structure of the blade disc body 312 can be avoided.

[0109] It should be noted that the diameter of the blade disc body 312 is greater than the diameter of the blade seat disc body 311 , so as to ensure that the blade of the blade disc body 312 protrudes out of the blade disc body 312 .

[0110] Furthermore, the positioning structure 314 includes a positioning block 3140 and a positioning groove 3141; one of the positioning block 3140 and the positioning groove 3141 is arranged on the tool seat disc body 311, and the other is arranged on the blade disc body 312; the positioning groove 3141 and the positioning block 3140 are matched and inserted so that the central axes of the tool seat disc body 311 and the blade disc body 312 coincide with each other. At this time, the coaxial setting of the tool seat disc body 311 and the blade disc body 312 is realized, and there is no need to manually judge the coaxiality of the tool seat disc body 311 and the blade disc body 312 with the naked eye and perform multiple position adjustments, thereby simplifying the installation procedure of the first circular tool disc 31.

[0111] The present invention discloses a further implementation of the positioning structure 314, specifically, the positioning groove 3141 is opened on the blade disc body 312, and the positioning block 3140 is arranged on the blade seat disc body 311; more specifically, the positioning groove 3141 is coaxially arranged with the blade disc body 312, and the positioning block 3140 body and the blade seat disc body 311 are coaxially arranged, so that after the positioning groove 3141 body is inserted into the positioning seat, the blade disc body 312 and the blade seat disc body 311 are coaxially arranged; of course, the positioning structure 314 can also adopt the following implementation mode, specifically, the positioning groove 3141 is opened on the blade seat disc body 311, and the positioning block 3140 is arranged on the blade disc body 312; more specifically, the positioning groove 3141 is coaxially arranged with the blade seat disc body 311, and the positioning block 3140 and the blade disc body 312 are coaxially arranged.

[0112] The present invention also discloses another embodiment of the positioning structure 314, wherein the positioning block 3140 is a non-equilateral right triangle or other irregular shapes, etc., and the positioning groove 3141 is also a non-equilateral right triangle or other irregular shapes, etc. having the same shape as the positioning block 3140. In this way, by matching the positioning groove 3141 and the positioning, the relative positioning of the blade disc body 312 and the blade seat disc body 311 can be achieved, thereby achieving a coaxial setting of the two.

[0113] Specifically, the locking structure 313 includes a first socket 3130 provided on the knife seat disc body 311, a second socket 3131 provided on the blade disc body 312, a screw and a nut; wherein the rod of the screw passes through the first socket 3130 and the second socket 3131 and is threadedly engaged with the nut, thereby locking the knife seat disc body 311 and the blade disc body 312. At this time, the knife seat disc body 311 and the blade disc body 312 can be replaced by unscrewing the screw and the nut.

[0114] More specifically, the blade disc body 312 is recessed on one side away from the blade seat disc body 311 toward the blade seat disc body 311 to form a receiving groove 3142; the second insertion hole 3131 is provided at the bottom of the receiving groove 3142, and the positioning groove 3141 is provided at the bottom of the receiving groove 3142; the head of the screw is located in the receiving groove 3142, and the thickness of the head of the screw is less than or equal to the depth of the receiving groove 3142, so that the head of the screw is prevented from protruding out of the blade disc body 312, thereby preventing the head of the screw from scraping other working equipment or operators during the working process. Furthermore, the receiving groove 3142 and the positioning groove 3141 are coaxially arranged.

[0115] Preferably, the surface tangent to the first circular cutter disc 31 and the second circular cutter disc 32 forms a first cut surface 39; here, the first cut surface 39 is the lower bottom surface of the blade disc body 312; the surface tangent to the second circular cutter disc 32 and the first circular cutter disc 31 forms a second cut surface; at this time, the first circular cutter disc 31 and the second circular cutter disc 32 can adopt the following first embodiment: the first cut surface 39 and the second cut surface can be set to have equal diameters, and in the horizontal direction parallel to the first cut surface 39, the center of the first cut surface 39 and the center of the second cut surface coincide with each other, such as Fig.13 As shown, the angle ∠D formed at the intersection of the first circular cutter disc 31 and the second circular cutter disc 32, at this time, the edges of the first circular cutter disc 31 and the second circular cutter disc 32 are flush, and the edges of the first circular cutter disc 31 and the second circular cutter disc 32 are simultaneously against the tire, which is not conducive to the tire entering between the two, that is, it is not conducive to the tire entering the angle ∠D; the first circular cutter disc 31 and the second circular cutter disc 32 can adopt the following second embodiment: preferably, the diameter of the first section 39 is greater than the diameter of the second section; in the horizontal direction parallel to the first section 39 (such as Fig.14 In the direction indicated by arrow F), the center of the first section 39 and the center of the second section are offset from each other. Fig.14 As shown, the intersection of the first circular cutter disc 31 and the second circular cutter disc 32 forms an angle ∠E. At this time, the edges of the right sides of the first circular cutter disc 31 and the second circular cutter disc 32 are staggered, and the first circular cutter disc 31 first contacts the tire and pushes the tire downward to contact the second circular cutter disc 32, thereby facilitating the tire to enter the right side of the first circular cutter disc 31 and the second circular cutter disc 32, that is, within the angle ∠E, and is easy to cut.

[0116] Since the tire does not engage with the first circular blade disc 31 and the second circular blade disc 32 at the beginning when the first circular blade disc 31 and the second circular blade disc 32 are cutting the tire initially, the tire is prone to sinking under the impact of the first circular blade disc 31 and the second circular blade disc 32, which makes the initial cutting difficult; therefore, the tire strip cutting machine further includes a pressing mechanism 38, which is used to push the tire so that the tire tread entering between the first circular blade disc 31 and the second circular blade disc 32 is close to the blade of the first circular blade disc 31, or close to the blade of the second circular blade disc 32. In this way, when the first circular blade disc 31 or the second circular blade disc 32 rotates, the tire tread is close to the first circular blade disc 31 or the second circular blade disc 32, and at this time, the first circular blade disc 31 and the second circular blade disc 32 can smoothly cut into the tire, thereby facilitating the subsequent engagement of the tire.

[0117] Specifically, the pressing mechanism 38 includes a telescopic cylinder 380, a bending arm 381 and a pressing head 382; the cylinder body of the telescopic cylinder 380 is hinged on the fixed frame 20, the telescopic rod of the telescopic cylinder 380 is hinged on one end of the bending arm 381, and the middle part of the bending arm 381 is hinged on the fixed frame 20; the pressing head 382 is installed at the other end of the bending arm 381; the pressing head 382 is used to push the tire, so that the pressing head 382 is extended between the tire and the receiving column 35, and the telescopic rod of the telescopic cylinder 380 is extended and retracted to drive the bending arm to rotate around the hinge point in the middle thereof. When the bending arm rotates, the pressing head 382 presses the tire upward or downward, so that the tire is close to the first circular cutter disc 31 or the second circular cutter disc 32.

[0118] Tire dicing machines, see Figure 15-26 , including a cutting device 40, a feeding device 60, a leaking device 70, a discharging device 80 and a driving device 90, wherein the driving device 90 is used to drive the feeding device 60, the cutting device 40 and the discharging device 80; the feeding device 60 is used to transport the strip-shaped tire strips to the cutting device 40; the cutting device 40 is used to cut the strip-shaped tire strips into block-shaped tire blocks; the leaking device 70 is used to leak the cut-in-block tire blocks into the discharging device 80; the discharging device 80 is used to output the cut-in-block tire blocks. That is, under the drive of the driving device 90, the strip-shaped tire strips are conveyed to the cutting device 40 through the feeding device 60, and the cutting device 40 is used to cut the strip-shaped tire strips into smaller tire blocks, and the cut tire blocks fall into the discharging device 80 through the leakage device 70, and the discharging device 80 is driven by the driving device 90 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.

[0119] Specifically, the cutting device 40 includes a mounting base 50, a cutting platform 407 and a rotating cutting assembly 401. The mounting base 50 is mounted on the material leakage device 70 and is used to fix the rotating cutting assembly 401 and the cutting platform 407, that is, the rotating cutting assembly 401 is fixedly mounted on the mounting base 50, and the cutting platform 407 is also fixed on the mounting base 50. Preferably, a fixing plate 408 is provided at both ends of the cutting platform 407, the bottom end of the fixing plate 408 is fixed on the mounting base 50, and the top end of the fixing plate 408 extends in the vertical direction, so that the top end surface of the fixing plate 408 is higher than the plane of the cutting platform 407. The cutting platform 407 is fixed to the fixing plate 408 by means of screws, so that when the cutting platform 407 is worn, it can be replaced to ensure the flatness of the platform. Of course, the cutting platform 407 is horizontally arranged on the front side of the rotating cutting component 401, and a cutting entrance 4071 is arranged at the front end of the cutting platform 407. With the help of the driving device 90 and the feeding device 60, the strip-shaped tire strip is fed into the cutting platform 407 from the cutting entrance 4071. That is, it can be understood that under the drive of the driving device 90, the feeding device 60 feeds the strip-shaped tire strip from the cutting entrance 4071 into the cutting platform 407, and uses the rotating cutting component 401 to cut the tire strip.

[0120] The rotating cutting assembly 401 includes a rotating assembly and a cutting blade block 404, wherein the rotating assembly is fixed on the mounting base 50, and the rotating assembly can rotate under the drive of the driving device 90, and the cutting blade block 404 is mounted on the rotating assembly, so that the cutting blade block 404 can rotate with the rotation of the rotating assembly. Preferably, the rotating assembly includes a rotating shaft 402 and a blade block mounting seat 405, wherein the rotating shaft 402 can rotate under the drive of the driving device 90, and the blade block mounting seat 405 is mounted on the rotating shaft 402, and the cutting blade block 404 is fixed on the blade block mounting seat 405, so that the cutting blade block 404 can rotate with the rotation of the rotating shaft 402. That is, it can be understood that the cutting blade block 404 is fixed to the blade block mounting seat 405 by screws, and the cutting blade block 404 can be replaced when it is worn. The blade block mounting seat 405 is key-connected to the rotating shaft 402 so that the blade block mounting seat 405 rotates with the rotation of the rotating shaft 402, and the cutting blade block 404 is fixed on the blade block mounting seat 405, and multiple cutting blade blocks 404 can be provided to improve cutting efficiency and reduce wear of the cutting blade block 404.

[0121] Of course, the cutting blade block 404 is mounted on the rotating assembly and is arranged at an angle to the cutting platform 407, that is, the cutting blade block 404 is arranged on the blade block mounting seat 405 and connected to the rotating shaft 402 through the blade block mounting seat 405, so that the cutting blade block 404 can rotate with the rotation of the rotating shaft 402, and the cutting blade block 404 can cut the strip-shaped tire strip into block-shaped tire blocks with the assistance of the cutting platform 407 during the rotation process. That is, it can be understood that Fig.17 As shown, the cutting edge of the cutting knife block 404 is the first cutting edge 4041, and the second cutting edge 4072 is arranged on the cutting platform 407. When the cutting knife block 404 rotates to the second cutting edge 4072 of the cutting platform 407, that is, the cutting edge (the first cutting edge 4041) of the cutting knife block 404 contacts the upper plane of the strip-shaped tire strip, and the second cutting edge 4072 of the cutting platform 407 contacts the lower plane of the strip-shaped tire strip, and the cutting platform 407 is horizontally arranged and stationary, and the cutting knife block 404 rotates with the rotation of the rotating shaft 402, thereby cutting the strip-shaped tire strip into block-shaped tire blocks.

[0122] In this preferred embodiment, in order to cut better, the angle between the cutting blade block 404 and the cutting platform 407 is set in the range of 3 to 6 degrees. By setting the cutting blade block 404 and the cutting platform 407 at an angle, an incision is first formed during the cutting process, which makes it easier to cut. In addition, compared with setting the first cutting edge 4041 of the cutting blade block 404 and the second cutting edge 4072 of the cutting platform 407 in parallel, the cutting line contact can be changed to the cutting point contact in the initial stage of cutting, and the resistance received by the cutting blade block 404 will be significantly reduced, making it easier to cut. Of course, when there are multiple cutting blade blocks 404 (such as three or four cutting blade blocks 404) disposed on the blade block mounting seat 405, when there are three cutting blade blocks 404 disposed on the blade block mounting seat 405, one cutting blade block 404 is disposed with a cutting direction opposite to that of the other cutting blade blocks 404, that is, if the cutting directions of two cutting blade blocks 404 are to the left, then the cutting direction of one cutting blade block 404 is to the right; or, if the cutting directions of two cutting blade blocks 404 are to the right, then the cutting direction of one cutting blade block 404 is to the left. When there are four cutting blade blocks 404, the cutting directions of two adjacent cutting blade blocks 404 can be opposite, or two adjacent cutting blade blocks 404 can be disposed to form a group, and the cutting directions of the two cutting blade blocks 404 in each group are opposite to the cutting directions of the two cutting blade blocks 404 in another group. In summary, the multiple cutting blades 404 arranged on the blade mounting seat 405 are adapted to change the different cutting directions of the cutting blades 404 in a reasonable manner, and all fall within the protection scope of the present invention. Since the tire strip will wear the cutting platform 407 during the cutting process, if only cutting is performed from one side, it is easy to cause wear on one side, reducing the service life of the cutting platform 407. By setting the cutting blades 404 in different cutting directions, the focus point during cutting can be changed, so that the wear on the cutting platform 407 is dispersed to both sides, which can increase the service life of the cutting platform 407.

[0123] In this preferred embodiment, the rotating assembly is also provided with a sleeve 409, and a notch 410 is provided on the sleeve 409. The notch 410 is in a "convex" shape, and the notch 410 enables the cutting blade block 404 to cut the tire strips in the process of rotation, and the tire blocks cut into blocks can enter the sleeve 409 from the notch 410. That is, it can be understood that the two sides of the notch 410 on the sleeve 409 are connected to the fixing plate 408, so that the tire blocks cut into blocks enter the sleeve 409 from the notch 410, and the cut blocks are prevented from flying out from the two sides of the notch 410.

[0124] As the preferred embodiment of the present invention, Fig. 20As shown, a heat dissipation cavity 4031 is provided on one end face of the first bearing seat 403 along the circumferential direction, and a plurality of heat dissipation ribs 4032 are provided between the upper wall and the lower wall of the heat dissipation cavity 4031. That is, it can be understood that by providing the heat dissipation cavity 4031 on the end face of the first bearing seat 403 and the heat dissipation ribs 4032 provided between the upper wall and the lower wall of the heat dissipation cavity 4031, the heat dissipation area for the bearing installation portion can be increased, so that the heat generated by the bearing when the rotating shaft 402 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 4032 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 403.

[0125] In this preferred embodiment, the feeding device 60 includes a rotating shaft 601 and a rotating shaft mounting frame 6023. The rotating shaft mounting frame 6023 is fixed to the cutting device 40 and is used to fix the rotating shaft 601 without affecting the rotation of the rotating shaft 601, that is, one end of the rotating shaft mounting frame 6023 is fixed to the outer wall of the sleeve 409, and the other end of the rotating shaft mounting frame 6023 is fixed to the rotating shaft 601 by means of a bearing and a second bearing seat 6022. A feeding wheel 602 is installed on the rotating shaft 601, so that the feeding wheel 602 can rotate with the rotation of the rotating shaft 601. The feeding wheel 602 is provided with saw teeth 6021, which are used to bite the strip of tire and convey the strip of tire to the cutting device 40 with the rotation of the feeding wheel 602. Of course, in order to facilitate the saw teeth 6021 to bite the strip-shaped tire strip, the saw teeth 6021 are arranged along the length direction of the rotating shaft 601, so that the strip-shaped tire strip can be smoothly sent into the cutting platform 407 from the cutting entrance 4071 of the cutting platform 407 under the drive of the driving device 90, and the cutting knife block 404 is used to cut the strip-shaped tire strip during the rotation process, and the cut tire blocks enter the sleeve 409 from the notch 410 of the sleeve 409.

[0126] In this preferred embodiment, the leakage device 70 includes an outer cover box 701 and a leakage box 702. The leakage box 702 is installed in the outer cover box 701. The outer cover box 701 is arranged below the cutting device 40, and the tire blocks cut by the cutting device can enter the leakage box 702. That is, the outer cover box 701 is arranged below the mounting base 50 in the cutting device 40, and is used to fix the cutting device 40. The leakage box 702 is installed in the outer cover box 701 and is located below the mounting base 50. Moreover, the inner cavity of the leakage box 702 is communicated with the inner cavity of the sleeve 409, so that the tire blocks cut into blocks can enter the leakage box 702. Specifically, a through hole 501 communicating with the inner cavity of the sleeve 409 is formed at the lower end of the mounting base 50, and an opening 703 is also formed at the upper end of the leakage box 702, so that the inner cavity of the leakage box 702 communicates with the inner cavity of the sleeve 409, and further, when the cutting knife block 404 cuts the strip-shaped tire strips into block-shaped tire blocks, the cut block-shaped tire blocks enter the leakage box 702 from the notch 410 of the sleeve 409.

[0127] In this preferred embodiment, the discharging device 80 includes a fixed frame 801 and a conveyor belt 802. The fixed frame 801 is set up in the outer cover box 701 and extends out of the outer cover box 701. The conveyor belt 802 is installed on the fixed frame 801 and is located below the leakage box 702. The lower end of the leakage box 702 is provided with a leakage port 704, so that the tire blocks cut into blocks fall from the leakage port 704 onto the conveyor belt 802. The transmission of the conveyor belt 802 is driven by the driving device 90, 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 407, and the outer cover box 701 and the sleeve 409 enclose the space between the cutting platform 407 and the conveyor belt, 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 701 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 701 is set, the black tire powder on the workers is not obvious.

[0128] In this preferred embodiment, the driving device 90 includes a first driving device 90 and a second driving device 90, and the first driving device 90 is used to synchronously drive the rotation of the rotating shaft 601 and the rotating shaft 402. The first driving device 90 includes a motor fixing bracket 901 and a motor 902, and the motor fixing bracket 901 is used to fix the motor 902. The output shaft of the motor 902 is connected with a driving pulley 903, which is used to protect the driving pulley 903. One end of the rotating shaft 402 is keyed to a driven pulley 904, and the driving pulley 903 and the driven pulley 904 are connected by a belt, so that the rotation of the rotating shaft 402 is driven by the drive of the motor 902 and the belt. Of course, a driving sprocket 905 is provided at the other end of the rotating shaft 402, and a driven sprocket 906 corresponding to the driving sprocket 905 is provided on the rotating shaft 601. The driving sprocket 905 and the driven sprocket 906 are connected by a transmission chain, so that the rotating shaft 601 is synchronously driven to rotate by the rotation of the rotating shaft 402 under the transmission of the transmission chain. The second driving device 90 is preferably a servo motor, which is fixed on the fixed frame 801 in the discharging device 80, and is used to drive the transmission of the conveyor belt 802, and is connected to the conveyor belt 802 through the output shaft of the motor 902, so that the transmission of the conveyor belt 802 is driven by the drive of the motor 902.

[0129] 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.
