Description

Technical Field

[0001] The utility model relates to the technical field of plastic recycling equipment, in particular to waste recycling and processing equipment for butyl rubber. Background Art

[0002] With the acceleration of the global industrialization process, rubber products are increasingly used in various industries, especially butyl rubber, which is widely used in the manufacture of tire inner tubes, medical bottle stoppers, waterproof materials and other fields due to its excellent air tightness, heat resistance and chemical resistance. Waste butyl rubber has good recycling value, so butyl rubber is generally cut into pieces. When shredding butyl rubber, traditional shredding equipment is easy to cause butyl rubber to splash and injure people, which poses a safety hazard. In addition, butyl rubber varies in size. When butyl rubber is large, it is easy for the butyl rubber to get stuck in the crushing roller when shredding, affecting the normal operation of the crushing work.

[0003] Announcement No. CN212528382U proposes a waste recycling and processing equipment for butyl rubber, including a body, a crushing roller is rotatably connected to the middle end of the body, and a storage chamber is opened at the lower end of the body, electric vibration rods are fixedly connected to the left and right sides of the upper end of the storage chamber, and a screening net is fixedly connected between the upper ends of the two electric vibration rods, and an electric rotating shaft is rotatably connected to the left and right sides of the upper end of the body, ..., a bracket is fixedly connected to the upper end of the support, and an electro-hydraulic push rod is fixedly connected to the middle position of the upper end of the bracket, a pressing plate is fixedly connected to the lower end of the electro-hydraulic push rod, and a plurality of cutting knives are fixedly connected to the left and right sides of the lower end of the pressing plate, push grooves are opened on the left and right sides of the lower end of the pressing plate and are located between two adjacent cutting knives, and a plurality of push plates are fixedly connected to the left and right sides of the upper end of the bracket, the lower end of the push plate is inserted through the push groove, and a tempered glass plate is connected to the front end of the bracket.

[0004] The above device pushes the pressing plate downward through the electro-hydraulic push rod, and uses the cutter at the bottom of the pressing plate to cut the butyl rubber waste. On the one hand, due to the different thickness of the butyl rubber waste, when the thinner parts on both sides are cut, the thicker part in the middle has not been cut, which will cause the blanking specifications to be too large, which is not conducive to subsequent crushing. In addition, the pressure cutting method not only requires a high degree of sharpness of the cutter blade, but also easily causes damage to the cutter. Therefore, we propose a waste recycling and processing equipment for butyl rubber to solve the above problems. Utility Model Content

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0029] The present application provides a waste recycling and processing equipment for butyl rubber, which is mainly used to solve the problem that in the prior art, a pressure plate is pushed down by an electro-hydraulic push rod, and a cutter at the bottom of the pressure plate is used to cut the butyl rubber waste. On the one hand, due to the different thickness of the butyl rubber waste, when the thinner parts on both sides are cut, the thicker part in the middle has not been cut, which will cause the blanking specifications to be too large, which is not conducive to subsequent crushing. In addition, the pressure cutting method not only requires a high degree of sharpness of the cutter, but also easily causes damage to the cutter. The following technical solutions are provided, which will be combined with Figure 1-Figure 4 Make a detailed description:

[0030] A waste recovery and processing device for butyl rubber, comprising:

[0031] Processing chamber 1, a feeding port 101 is provided on the upper front side of the processing chamber 1;

[0032] The strip cutting mechanism 2 is used to cut the butyl rubber waste into strips. The strip cutting mechanism 2 includes a fixed plate 201 fixed in the middle of the processing chamber 1. The surface of the fixed plate 201 is evenly spaced with first strip-shaped through holes 2011. The first cutting knives 202 are symmetrically slidably inserted on both sides of the first strip-shaped through holes 2011. A clamping plate 203 is slidably arranged above the fixed plate 201 in the processing chamber 1. The surface of the clamping plate 203 is evenly spaced with second strip-shaped through holes 2031. The second strip-shaped through holes 2031 have the same specifications as the first strip-shaped through holes 2011 and are located opposite to each other.

[0033] The lifting mechanism 3 is arranged on the upper side of the processing chamber 1 and is used to drive the clamping plate 203 to move up and down;

[0034] A driving member 4 is disposed at the bottom of the fixing plate 201 and is used to drive the first cutting knife 202 to slide along the first strip-shaped through hole 2011;

[0035] The pelletizing mechanism 5 is arranged at the bottom of the processing chamber 1 and is used for shredding the strip-shaped butyl rubber waste.

[0036] Specific implementation steps:

[0037] When in use, butyl rubber waste is put in from the feeding port 101 and made to fall on the fixed plate 201. Then, the lifting mechanism 3 drives the clamping plate 203 to move downward to clamp and fix the butyl rubber waste. At the same time, the blade head of the first cutting knife 202 can pass through the butyl rubber waste. Finally, the driving member 4 is started, and the first cutting knife 202 can slide along the first strip through hole 2011 to cut the butyl rubber waste into strips. The strip-shaped butyl rubber waste falls from the first strip through hole 2011. The pelletizing mechanism 5 can further cut the butyl rubber waste, thereby realizing the effective recycling of butyl rubber and avoiding the problems of safety hazards and operation troubles.

[0038] like Figure 4 As shown, in some embodiments, the lifting mechanism 3 includes a rotating rod 301 rotatably connected between the inner side walls of the processing chamber 1, a first motor 302 is installed on one side outer wall of the processing chamber 1, and the output shaft of the first motor 302 is connected to one end of the rotating rod 301, and the two sides of the rotating rod 301 are constructed with threads with opposite spiral directions, and the driving blocks 303 are symmetrically threadedly connected, the top of the driving block 303 is slidably connected to the inner top wall of the processing chamber 1, and the bottom of the driving block 303 is hinged with a hinged plate 304, and a lifting plate 305 is slidably arranged below the rotating rod 301 inside the processing chamber 1, and one end of the hinged plate 304 away from the driving block 303 is hinged to the lifting plate 305, and connecting plates 306 are fixed at the four corners of the bottom surface of the lifting plate 305, and the clamping plate 203 is fixed at the bottom of the connecting plate 306. More specifically, when the first motor 302 is started, its output shaft will drive the rotating rod 301 to rotate. Since threads with opposite spiral directions are constructed on both sides of the rotating rod 301, and the driving blocks 303 are symmetrically connected to the threads, during the rotation of the rotating rod 301, the two driving blocks 303 will move inward or outward at the same time under the guidance of the spirals, and cooperate with the hinged plate 304 to convert the rotational motion into linear motion. When the hinged plate 304 pushes the lifting plate 305, the lifting plate 305 will move up or down, thereby driving the clamping plate 203 to move up and down, thereby clamping or releasing the butyl rubber waste.

[0039] like Figure 4As shown, in some embodiments, the driving member 4 includes a guide rod 401 symmetrically fixed on both sides of the processing chamber 1, and a slide plate 402 is symmetrically slidably connected on both sides of the surface of the guide rod 401. The first cutting knife 202 is fixed on the top of the slide plate 402. Hydraulic cylinders 403 are installed on the outer walls of both sides of the processing chamber 1. The piston end of the hydraulic cylinder 403 penetrates the chamber wall of the processing chamber and is connected to the middle part of the slide plate 402. More specifically, when the hydraulic cylinder 403 is working, it can push the slide plate 402 to move along the guide rod 401, and then drive the first cutting knife 202 to move along the first strip through hole 2011 to achieve the cutting of butyl rubber waste.

[0040] like Figure 4 As shown, in some embodiments, the first cutting blade 202 is in the shape of a right triangle, and the thickness gradually becomes thinner from one side close to the right angle to the other side. More specifically, the first cutting blade 202 is arranged in the shape of a right triangle, so that when the two first cutting blades 202 are close to each other, they can pierce from a point in the middle of the butyl rubber waste, and then cut to both sides, thereby quickly completing the slitting of the butyl rubber waste.

[0041] like Figure 4 As shown, in some embodiments, the cross-sections of the first strip-shaped through hole 2011 and the second strip-shaped through hole are both isosceles trapezoidal, and the diameter of the upper port is larger than the diameter of the lower port. More specifically, since the cross-sections of the first strip-shaped through holes 2011 are both isosceles trapezoidal, when the adjacent first strip-shaped through holes 2011 are close enough, the partition between the two adjacent first strip-shaped through holes 2011 is triangular, so that after the butyl rubber waste is cut into strips, the strip-shaped butyl rubber waste will automatically fall down from the first strip-shaped through holes 2011.

[0042] like Figure 4As shown, in some embodiments, the pelletizing mechanism 5 includes a mounting rod 501 that is rotatably connected between the inner side walls of the processing chamber 1 at intervals, a second motor 502 is installed on one side outer wall of the processing chamber 1, and the output shaft of the second motor 502 is connected to one end of the mounting rod 501, a processing roller 503 is fixedly arranged in the middle of the mounting rod 501, and second cutting blades 504 are fixedly arranged on the surface of the processing roller 503 at equal intervals, and an annular groove 5031 is constructed on the surface of the processing roller 503 at the interval between the second cutting blades 504, and the second cutting blades 504 on the two processing rollers 503 are staggered, and the second cutting blades 504 on one of the processing rollers 503 are staggered. The heads of the second cutting blades 504 are embedded in the annular groove 5031. More specifically, when the second motor 502 is started, its power is transmitted to the mounting rod 501 through the output shaft, driving the mounting rod 501 to rotate. The rotation of the mounting rod 501 drives the processing roller 503 fixed thereon to rotate. When the rubber material passes through the processing roller 503, the rotating processing roller 503 and the second cutting blades 504 thereon shear and crush the rubber. Since the second cutting blades 504 on the two processing rollers 503 are staggered, this increases the cutting efficiency and uniformity, ensuring that the rubber can be quickly and evenly cut into small pieces.

[0043] like Figure 4 As shown, in some embodiments, the second cutting blade 504 is annular, and its thickness gradually becomes thinner from one side close to the processing roller 503 to the other side. More specifically, the annular second cutting blade 504 is not easy to get stuck, and the thickness of the blade gradually becomes thinner from one side close to the processing roller 503 to the other side. The thicker part provides stronger rigidity and support, which helps the blade maintain its shape and resist the force during the cutting process, thereby reducing the possibility of bending and breaking. The thinner edge reduces the resistance of friction with the rubber, making it easier for the blade to cut into the rubber, thereby improving the smoothness and efficiency of cutting.

[0044] like Figure 4 As shown, in some embodiments, a material guide plate 505 is fixedly provided at a position of the inner wall of the processing chamber 1 corresponding to the processing roller 503, and the material guide plate 505 is arc-shaped. More specifically, the main function of the material guide plate 505 is to guide materials such as butyl rubber into the processing roller 503 for cutting. Since the material guide plate 505 is arc-shaped, it can better match the circular surface of the processing roller 503 and smoothly guide the material. The cut rubber particles slide along the material guide plate 505 to the middle of the bottom of the processing chamber 1.

[0045] like Figure 2 As shown, in some embodiments, a rectangular notch 102 is constructed at the bottom of the processing bin 1, and a conveyor belt 6 is installed inside the rectangular notch 102. More specifically, the use of the conveyor belt 6 facilitates the transportation of the cut rubber particles to the next processing step or storage location, thereby realizing rapid transfer and processing of materials.

[0046] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
