[0002] High temperature resistant rubber is a special rubber material that can maintain stable physical and mechanical properties in high temperature environments. It is widely used in aerospace, automobile manufacturing, petrochemical, electronic and electrical appliances, etc. In the production and processing of high temperature resistant rubber, waste rubber residues will be generated. The recycling of rubber waste can not only improve resource utilization efficiency, but also has great significance for environmental protection.

[0003] At present, the recycling of waste rubber is usually done by using crushing equipment to decompose and cut it. After being screened and classified, the cut and crushed rubber waste can be put into the production of rubber products again. However, in the process of cutting and crushing rubber, the existing crushing equipment often uses crushing rollers or cutting knives to cut and crush the rubber in a single direction. In this way, when processing block rubber, it is often cut into thin and long rubber strips, which need to be collected again and cut again, which affects the crushing efficiency, and the crushing effect still needs to be improved.

[0017] Beneficial effects of the present invention:

[0018] (1) By setting up a longitudinal cutting component and a transverse crushing component, the rubber material is transported from the feeding component to the crushing box. First, the longitudinal cutting component is used to cut the block rubber into slender rubber strips. The rubber strips fall into the guide ramp and slide onto the unloading conveyor belt. The conveying cavity formed by the partition and the unloading conveyor belt can effectively correct and guide the rubber strips, so that the slender rubber strips can be transported straight along the length direction. Then, the transverse crushing component is used to cut the rubber strips transversely. The longitudinal cutting and transverse cutting are coordinated to cut and crush the rubber material into fine particles, which effectively improves the rubber crushing effect.

[0019] (2) By setting up a rake comb assembly, when the transverse crushing assembly moves back and forth to cut, the reciprocating comb teeth will be able to comb and guide the rubber strip that falls on the material guide ramp, so that the rubber strip can slide down along the length direction for transportation, so as to ensure that it can enter the transportation cavity straightly. At the same time, the reciprocating rake rod can hook the rubber strip that is tilted and blocked at the end of the transportation cavity, and pull it into the transportation cavity, so that the rubber strip is smoothly transported in the correct direction. The combing action combined with the hooking and rake action can effectively correct the deviation of the rubber strip and ensure that the rubber strip can smoothly achieve the transverse cutting process.

[0020] (3) When it is necessary to adjust the thickness of the cut rubber strip, the second motor drives one set of screws to rotate, and drives the other set of screws to rotate synchronously through the second transmission belt. By utilizing the thread engagement between the screws and the screw sleeves, each cutting blade can move synchronously along the screws on the fixed slide rods, so as to adjust the distance between the two sets of cutting blades, and further adjust the thickness of the cut rubber strip.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown in

[0034] Specifically, by setting up the longitudinal cutting component 4 and the transverse crushing component 7, the rubber material is conveyed from the feeding component 2 to the crushing box 3, and the longitudinal cutting component 4 is first used to cut the block rubber into slender rubber strips, and the rubber strips fall into the guide ramp 5 and slide onto the unloading conveyor belt 62. The conveying cavity formed by the partition 63 and the unloading conveyor belt 62 can effectively correct and guide the rubber strip, so that the slender rubber strip can be conveyed straight along the length direction, and then the transverse crushing component 7 is used to transversely cut the rubber strip. The longitudinal cutting and transverse cutting are coordinated to cut and crush the rubber material into fine particles, which effectively improves the rubber crushing effect.

[0035] like Figure 6 and Figure 7 As shown, the rake comb assembly 9 includes a mounting plate 91 and a mounting frame 92. The mounting plate 91 is arranged above the unloading bracket 6. A plurality of rake rods 911 are fixedly arranged at equal intervals on one side of the mounting plate 91. Each rake rod 911 corresponds to a conveying cavity one by one. The transverse crushing assembly 7 drives the rake rod 911 to make a linear reciprocating movement in the corresponding conveying cavity through the first connecting rod 732. The mounting frame 92 is arranged in the material guide ramp 5. A plurality of comb teeth 921 are fixedly arranged at equal intervals on the bottom of the mounting frame 92. The mounting plate 91 drives the comb teeth 921 to make a linear reciprocating movement along the inclined surface direction of the material guide ramp 5 through the second connecting rod 94.

[0036] Specifically, by setting up the rake comb assembly 9, when the transverse crushing assembly 7 moves back and forth for cutting, the rake rod 911 will be driven by the first connecting rod 732 to make a straight reciprocating movement in the conveying cavity, and at the same time, the mounting plate 91 will drive the comb teeth 921 to make a straight reciprocating movement along the inclined surface direction of the material guide ramp 5 through the second connecting rod 94. During this process, the reciprocating comb teeth 921 will be able to comb and guide the rubber strips that fall onto the material guide ramp 5, so that the rubber strips can slide down along the length direction for transportation to ensure that they can enter the conveying cavity straightly. At the same time, the reciprocating rake rod 911 can hook the rubber strips that are tilted and blocked at the end of the conveying cavity, and pull them into the conveying cavity, so that the rubber strips are smoothly conveyed in the correct direction. The combing action combined with the hooking and rake action can effectively correct and straighten the rubber strips, ensuring that the rubber strips can smoothly achieve the transverse cutting process.

[0037] like Figure 1 and Figure 2 As shown, the feeding assembly 2 includes a support frame 21, a feeding motor 22 and a feeding conveyor belt 23. The support frame 21 is fixedly installed on the upper end of the box body 1, the feeding motor 22 is fixedly arranged on one side of the support frame 21, and both ends of the feeding conveyor belt 23 are rotatably installed on the transmission shaft, and the output end of the feeding motor 22 is connected to one of the transmission shafts.

[0038] Specifically, when the feeding motor 22 starts, it will drive the transmission shaft to rotate, and the transmission shaft will drive the feeding conveyor belt 23 to continuously perform a conveying motion, enabling the feeding conveyor belt 23 to convey the rubber material on its surface forward into the crushing box 3 for subsequent crushing treatment.

[0039] As Figure 2 , Figure 3 and Figure 4 shown in the figure, the longitudinal strip cutting assembly 4 includes a pair of screws 41. A sleeve rod 42 is rotatably sleeved at both ends of each screw 41. The sleeve rod 42 is rotatably matched with the crushing box 3. A synchronous gear 43 is fixedly sleeved on one of the sleeve rods 42 at one end. The two synchronous gears 43 are meshed with each other. A fixed slide rod 44 is fixedly arranged between the sleeve rods 42 at both ends. The fixed slide rod 44 is evenly distributed around the screw 41. A number of cutting blades 45 are slidably penetrated through the fixed slide rod 44 at equal intervals. A screw sleeve 46 is fixedly arranged at the center of the cutting blade 45. The screw 41 is threadedly penetrated and matched with the screw sleeve 46. The cutting blades 45 on the two screws 41 are arranged in a staggered manner.

[0040] Furthermore, a first motor 31 and a second motor 32 are respectively fixedly arranged on the outer wall of the crushing box 3. The output shaft of the first motor 31 is connected to one of the sleeve rods 42 through a first transmission belt 33. The output end of the second motor 32 is connected to one of the screws 41. The two screws 41 are connected through a second transmission belt 34.

[0041] Specifically, when cutting and crushing, the first motor 31 starts and drives the sleeve rod 42 to rotate through the first transmission belt 33. Since the sleeve rods 42 at both ends are supported and fixed by the fixed slide rod 44, the sleeve rod 42 will drive the cutting blade 45 to rotate synchronously through the fixed slide rod 44. At the same time, due to the meshing effect of the synchronous gears 43, the other set of cutting blades 45 will also rotate synchronously. The two sets of cutting blades 45 are arranged in a staggered manner and rotate in opposite directions, effectively improving the shearing strength and enabling the block-shaped rubber material to be cut into slender rubber strips. When it is necessary to adjust the thickness of the cut rubber strips, the second motor 32 starts, drives one set of screws 41 to rotate, and drives the other set of screws 41 to rotate synchronously through the second transmission belt 34. By utilizing the threaded cooperation between the screw 41 and the screw sleeve 46, each cutting blade 45 can move synchronously along the screw 41 on the fixed slide rod 44, thereby adjusting the distance between the two sets of cutting blades 45 and further adjusting the thickness of the cut rubber strips.

[0042] It should be noted that the screw 41 in this application is a bidirectional screw, and the cutting blades 45 are symmetrically distributed on the threaded parts with opposite helix directions at both ends of the screw 41. When the screw 41 rotates, the cutting blades 45 will also move closer to or away from each other accordingly, thereby realizing the adjustment process of the cutting distance.

[0043] As shown Figure 6 and Figure 7 shown, the horizontal crushing assembly 7 includes a fixing frame 71. Both ends of the fixing frame 71 are fixedly connected to the blanking support 6. A push-pull cylinder 72 is fixedly arranged at the top end of the fixing frame 71. The output end of the push-pull cylinder 72 is fixedly connected to a blade seat 73. A cutting edge 74 is fixedly arranged at the bottom of the blade seat 73. Corresponding blade openings 64 are arranged on the partition plates 63 opposite to the cutting edge 74.

[0044] Furthermore, slide rails 711 are arranged on the inner walls of both sides of the fixing frame 71. Both ends of the blade seat 73 extend with sliders 731. The sliders 731 are adaptively and slidably installed in the slide rails 711.

[0045] Specifically, by setting the horizontal crushing assembly 7, when the push-pull cylinder 72 is started, it will push the blade seat 73 to move downward. During this process, the sliders 731 at both ends of the blade seat 73 always slide in the slide rails 711, ensuring the stability during the lifting and moving process. The blade seat 73 will drive the cutting edge 74 to move downward synchronously until the cutting edge 74 extends into the blade opening 64, so that the long and thin rubber strips in each conveying channel can be horizontally cut simultaneously. It should be noted that during the lifting and cutting process, the push-pull stroke of the push-pull cylinder 72 needs to be set in advance so that the limit position of the downward movement of the cutting edge 74 just reaches the surface of the blanking conveyor belt 62, which can ensure the cutting effect while avoiding excessive movement of the cutting edge 74 and causing collision damage.

[0046] As shown Figure 7 and Figure 8 shown, one end of the first connecting rod 732 is rotationally matched with the blade seat 73, and the other end of the first connecting rod 732 is rotationally matched with the mounting plate 91. Both ends of the mounting plate 91 are fixedly connected with first sliding seats 912. Side plates 93 are fixedly arranged on both sides of the blanking support 6. Slide ways 931 are arranged through the side plates 93. The first sliding seats 912 are adaptively and slidably installed in the slide ways 931. A return spring 932 is arranged between one end of the first sliding seat 912 and the inner wall of the slide way 931.

[0047] Specifically, during the reciprocating up and down movement of the blade seat 73, it will drive the mounting plate 91 to perform corresponding linear reciprocating movement through the first connecting rod 732, so that each rake rod 911 can rake back and forth in the corresponding conveying channel. Due to the constraint and limiting effect of the slide way 931 on the first sliding seat 912, the first sliding seat 912 will always slide linearly in the slide way 931. Therefore, the rake rod 911 will also always perform linear reciprocating motion and will not easily deviate or shake, which is beneficial to improving stability.

[0048] As shown Figure 7 , Figure 8 and Figure 9As shown, a pivot shaft 96 is rotatably installed at the bottom of the material guiding inclined table 5. Both ends of the pivot shaft 96 are fixedly connected to the bottom ends of the swing rods 95. A limiting sliding groove 951 is provided through the swing rod 95. One end of the second connecting rod 94 is rotatably fitted with the first sliding seat 912, and the other end of the second connecting rod 94 is rotatably fitted with the swing rod 95.

[0049] Furthermore, second sliding seats 922 are fixedly connected to both ends of the mounting frame 92. Sliding grooves 51 are provided through both side walls of the material guiding inclined table 5. The direction of the sliding grooves 51 is parallel to the inclined surface direction of the material guiding inclined table 5. The second sliding seats 922 are slidably installed in the sliding grooves 51 in a matching manner. A linkage pin 923 is fixedly connected to the outer wall of the second sliding seat 922, and the linkage pin 923 is slidably installed in the corresponding limiting sliding groove 951 in a matching manner.

[0050] Specifically, during the horizontal movement of the first sliding seat 912, it will drive the swing rods 95 at both ends to perform corresponding reciprocating swinging movements around the pivot shaft 96 through the second connecting rod 94. During the back-and-forth swinging of the swing rods 95, by means of the sliding fit between the linkage pin 923 and the limiting sliding groove 951, the second sliding seat 922 can perform corresponding reciprocating sliding movements along the sliding groove 51, thereby driving the comb teeth 921 to perform back-and-forth combing actions. And because the sliding groove 51 is parallel to the inclined surface direction of the material guiding inclined table 5, the comb teeth 921 will always move back and forth along the inclined surface direction, which is beneficial to the combing process.

[0051] As Figure 1 and Figure 6 shown, the material box 8 is fixedly arranged at the bottom inside the box body 1. An outlet 81 is provided on one side of the material box 8. The outlet 81 penetrates through the box body 1 and extends outwards. In this way, it is convenient for the rubber particles in the material box 8 to directly discharge from the outlet 81 without moving the internal material box 8.

[0052] The working principle of the present invention: As Figures 1 - 9As shown, when in use, the rubber material is placed on the feeding conveyor belt 23, and the feeding conveyor belt 23 conveys the block-shaped rubber forward to the crushing box 3. When cutting and crushing is performed, the first motor 31 is started, and the sleeve rod 42 is driven to rotate through the transmission belt 1 33. Since the sleeve rods 42 at both ends are supported and fixed by the fixed slide rod 44, the sleeve rod 42 will drive the cutting blade 45 to rotate synchronously through the fixed slide rod 44. At the same time, the meshing action of the synchronous gear 43 is used to make the other group of cutting blades 45 rotate synchronously. The two groups of cutting blades 45 are staggered and rotate in opposite directions, which effectively improves the shear strength and can cut the block-shaped rubber material into slender rubber strips. When the thickness of the cut rubber strip needs to be adjusted, the second motor 32 is started to drive one group of screws 41 to rotate, and the other group of screws 41 is driven to rotate synchronously through the transmission belt 34. By utilizing the threaded cooperation between the screw 41 and the screw sleeve 46, each cutting blade 45 can move synchronously along the screw 41 on the fixed slide rod 44, so that the distance between the two groups of cutting blades 45 can be adjusted, and then the thickness of the cut rubber strip can be adjusted.

[0053] The cut elongated rubber strip falls directly onto the material guide ramp 5. When the transverse crushing assembly 7 moves back and forth for cutting, it will drive the rake rod 911 to move back and forth in a straight line in the conveying cavity through the first connecting rod 732. At the same time, the mounting plate 91 will drive the comb teeth 921 to move back and forth in a straight line along the inclined direction of the material guide ramp 5 through the second connecting rod 94. During this process, the reciprocating comb teeth 921 will be able to comb and guide the rubber strip that falls on the material guide ramp 5, so that the rubber strip can slide downward along the length direction for transportation to ensure that it can enter the conveying cavity straightly. At the same time, the reciprocating rake rod 911 can hook the rubber strip that is tilted and blocked at the end of the conveying cavity, and pull it into the conveying cavity, so that the rubber strip is smoothly conveyed in the correct direction. The combing action combined with the hooking and rake action can effectively correct the rubber strip. The push-pull cylinder 72 is started, pushing the blade seat 73 downward, and the blade seat 73 will drive the cutting blade 74 to move downward synchronously until the cutting blade 74 extends into the cutting edge 64, so that the slender rubber strips in each conveying cavity can be cut horizontally at the same time, and the cut rubber particles will fall directly into the material box 8 and be discharged from the discharge port 81.

[0054] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
