Description

Technical Field

[0001] The invention relates to the technical field of plastic pipe recycling, in particular to a waste plastic recycling and processing device for polymer plastic pipe processing. Background Art

[0002] Plastic pipes are used in all walks of life and are common and important components. In order to save resources, some damaged and old plastic pipes are recycled and reused. The recycling process mainly includes collection, collection, classification and sorting, cleaning and drying, crushing and granulation, resource recycling and environmental protection requirements. The crushing process will use a plastic pipe crusher to break the plastic pipe into small pieces or powder for easy transportation and subsequent processing.

[0003] The scrap recycling station will crush the plastic pipes. During the crushing operation, the staff will manually throw the plastic pipes into the feed box of the crushing equipment. The height of the feed box is relatively high, which increases the staff's feeding intensity. In addition, manual feeding cannot control the unit feeding amount in a more standard way, which may cause excessive blockage or reduce production efficiency due to small amounts. For longer plastic pipes, the staff also need to support them for a period of time after the pipes enter the feed box to prevent them from slipping out of the feed box, further increasing the staff's labor intensity. Summary of the invention

[0004] In response to the above problems, the present application provides a waste plastic recycling and processing device for polymer plastic pipe processing, which solves the problem in the prior art that workers manually throw plastic pipes into the feed box of the crushing equipment. The height of the feed box is relatively high, which increases the loading intensity of the workers. In addition, manual loading cannot control the unit loading amount in a relatively standard manner, which may cause excessive blockage or reduce production efficiency due to small amounts. For longer plastic pipes, the workers also need to support the pipes for a period of time after they enter the feed box to prevent them from slipping out of the feed box, further increasing the labor intensity of the workers.

[0007] Two first and second oil cylinders are installed at the bottom of the silo to drive the silo to rise, fall and tilt;

[0008] A plurality of push plates are slidably installed on the inner side of the silo to push the plastic tubes into the feed box. The sliding resistance between the push plates and the silo increases from top to bottom. When the inclination angle of the silo gradually increases, the push plates slide from top to bottom to achieve quantitative feeding of the plastic tubes.

[0009] A connecting plate is movably installed on the outer side of the push plate, which is used to connect the push plates at adjacent positions, so as to adjust the height of the plastic pipe pushed at a single time according to the difference of the plastic pipes, thereby controlling the single feeding amount.

[0010] Furthermore, the telescopic ends of the first oil cylinder and the second oil cylinder are both hinged with an articulated assembly, a plug-in column is fixedly installed on the top of the articulated assembly, and a plug-in groove is opened at the bottom of the silo, and the plug-in groove is plugged and matched with the plug-in column;

[0011] The bottom of the crushing unit is fixedly connected to the frame, the bottom of the first oil cylinder is hinged to the top of the frame, and the bottom of the second oil cylinder is fixedly connected to the top of the frame.

[0012] Furthermore, a plurality of slide rails are symmetrically fixedly installed on the inner side of the silo, and the surface roughness of the plurality of slide rails increases from top to bottom. A slide groove for sliding engagement with the slide rail is provided at the end of the push plate, and two blocks are symmetrically fixedly installed at one end of the silo close to the feed box.

[0013] Furthermore, a connecting groove is opened on the outer side of the push plate, a connecting plate is installed on the outer side of the push plate, and the connecting plate and the push plate are fixedly connected by connecting bolts.

[0014] Furthermore, a movable plate is slidably installed on the inner side of the push plate, a plurality of first springs are fixedly installed between the movable plate and the inner side of the push plate, a pressure sensor is fixedly installed on the inner side of the push plate, and the pressure sensor is electrically connected to the first oil cylinder.

[0015] Furthermore, a baffle is hinged on the top of the feed port of the feed box, and the baffle cooperates with the silo.

[0016] Furthermore, a high-efficiency feeding mechanism is installed outside the silo, and the high-efficiency feeding mechanism includes a plurality of fixed rods, the bottom of the fixed rods is fixedly installed on the top of the frame, and a slide is fixedly installed on the top of the fixed rods;

[0017] Two grooves are symmetrically arranged on the top of the slide, and a plurality of balls are inlaid and rotatably installed on the bottom of the silo, and the balls are slidably installed inside the grooves.

[0018] Furthermore, a positioning rod is slidably installed through the end of the silo, a second spring is fixedly installed between the positioning rod and the end of the silo, and the second spring is movably sleeved on the periphery of the positioning rod;

[0024] The plastic tubes slide down one by one under the push of the push plate. The subsequently sliding plastic tubes can push the plastic tubes remaining in the feed box, making it difficult for the plastic tubes to slip with the crushing rollers of the crushing unit. The baffle rotates in the opposite direction and resets under the action of gravity, which has a certain pushing effect on the plastic tubes exposed at the end of the feed box, that is, it has a pushing effect on the plastic tubes that slide into the feed box last, further reducing the slippage between the plastic tubes and the crushing unit.

[0040] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0041] First embodiment:

[0042] As shown in Figure 2, Figure 3 , Figure 4 , Figure 8 As shown, an embodiment of the present invention provides a waste plastic recycling and processing device for polymer plastic pipe processing, comprising a crushing unit 2 for crushing plastic pipes, a feed box 3 is connected and fixedly installed on the top of the crushing unit 2, a quantitative feeding mechanism 4 is installed outside the feed box 3, and the quantitative feeding mechanism 4 includes a silo 46 for loading plastic pipes;

[0043] Two first oil cylinders 41 and second oil cylinders 42 are installed at the bottom of the silo 46 to drive the silo 46 to rise, fall and tilt;

[0044] A plurality of push plates 47 for pushing the plastic tubes into the feed box 3 are slidably installed inside the silo 46. The sliding resistance between the push plates 47 and the silo 46 increases from top to bottom. When the inclination angle of the silo 46 gradually increases, the push plates 47 slide from top to bottom to achieve quantitative feeding of the plastic tubes.

[0045] A plurality of slide rails 411 are symmetrically fixedly installed on the inner side of the silo 46, and the surface roughness of the plurality of slide rails 411 increases successively from top to bottom, so that the force required for the push plate 47 to slide downward is different and increases successively from top to bottom. As the silo 46 tilts, the push plate 47 slides successively from top to bottom to realize quantitative material discharge, and a slide groove 414 is provided at the end of the push plate 47 for sliding engagement with the slide rail 411. Two blocks 412 are symmetrically fixedly installed at one end of the silo 46 close to the feed box 3 to prevent the push plate 47 from separating from the silo 46.

[0046] In this embodiment, when working with a single silo 46, the staff puts the plastic pipe into the silo 46, the telescopic ends of the first cylinder 41 and the second cylinder 42 extend synchronously, driving the silo 46 to move upward, the telescopic end of the first cylinder 41 extends, driving the silo 46 and the push plate 47 to tilt, and the push plate 47 slides downward in turn, pushing the plastic pipe into the feed box 3, and then into the crushing unit 2 for crushing, realizing quantitative unloading, so that the crushing unit 2 is basically in the best working state.

[0047] Specifically, a connecting plate 410 is movably installed on the outer side of the push plate 47, which is used to connect the push plates 47 at adjacent positions, and then adjust the height of a single push of the plastic pipe according to the difference of the plastic pipes, thereby controlling the single feed amount. A connecting groove 48 is opened on the outer side of the push plate 47, and a connecting plate 410 is installed on the outer side of the push plate 47. The connecting plate 410 and the push plate 47 are fixedly connected by connecting bolts 49.

[0048] In this embodiment, for different plastic pipes, such as those with different thicknesses and wall thicknesses, the crushing efficiency of the crushing unit 2 is different, and thus the single feed amount needs to be adjusted. The staff can use the connecting bolts 49 and the connecting plate 410 to fix and connect multiple adjacent push plates 47 to increase the single feed amount, thereby improving the flexibility of the device and adapting to more actual production environments.

[0049] Specifically, the telescopic ends of the first oil cylinder 41 and the second oil cylinder 42 are both hinged with an articulated assembly 43, a plug-in column 44 is fixedly installed on the top of the articulated assembly 43, and a plug-in groove 45 is opened at the bottom of the silo 46, and the plug-in groove 45 is plugged with the plug-in column 44; The bottom of the crushing unit 2 is fixedly connected to the frame 1 , the bottom of the first oil cylinder 41 is hinged to the top of the frame 1 , and the bottom of the second oil cylinder 42 is fixedly connected to the top of the frame 1 .

[0050] Specifically, a movable plate 415 is slidably installed on the inner side of the push plate 47, and a plurality of first springs 416 are fixedly installed between the movable plate 415 and the inner side of the push plate 47 for resetting the movable plate 415. A pressure sensor 417 is fixedly installed on the inner side of the push plate 47, and the pressure sensor 417 is electrically connected to the first oil cylinder 41.

[0051] In this embodiment, under the blocking effect of the plastic tube, the movable plate 415 moves the extrusion pressure sensor 417, and the first spring 416 is compressed. When all the plastic tubes on the top layer enter the feed box 3, the pressure sensor 417 of the top layer block push plate 47 is subjected to reduced pressure, and the movable plate 415 is reset under the elastic force of the first spring 416. The pressure sensor 41 controls the extension of the telescopic end of the first oil cylinder 41 with the help of the data processor, so that the second push plate 47 pushes the plastic tube to slide down, realizing the equal discharge of the plastic tube. The subsequent sliding plastic tube can push the remaining plastic tube in the feed box 3, so that the plastic tube is not easy to slip with the crushing roller of the crushing unit 2.

[0052] Specifically, a baffle 413 is hinged on the top of the feed port of the feed box 3 to seal the feed box 3 and reduce the debris generated by crushing from splashing to the external environment. The baffle 413 cooperates with the silo 46.

[0053] In this embodiment, the hopper 46 moves upward to drive the baffle 413 to rotate and open, all the plastic pipes slide down, the telescopic end of the first cylinder 41 is shortened, the hopper 46 moves downward, and the baffle 413 rotates in the opposite direction and resets under the action of gravity, which has a certain driving effect on the plastic pipe exposed at the end of the feed box 3, and can also improve the crushing efficiency of the crushing unit 2. In addition, the baffle 413 can reduce the possibility of splashes generated by crushing flying out of the feed box 3, thereby ensuring the production safety of the staff.

[0054] Second embodiment:

[0055] like Figure 1 , Figures 3 to 7 As shown, the difference from the above embodiment is that a high-efficiency feeding mechanism 5 is installed outside the silo 46 to increase the replenishment speed of the silo 46, thereby improving the overall crushing efficiency. The high-efficiency feeding mechanism 5 includes a plurality of fixed rods 51, the bottom of the fixed rods 51 is fixedly installed on the top of the frame 1, and a slide 52 is fixedly installed on the top of the fixed rods 51;

[0056] Two grooves 59 are symmetrically provided on the top of the slide 52 , and a plurality of balls 53 are rotatably mounted on the bottom of the silo 46 , which are used to reduce the friction resistance between the bottom of the silo 46 and the top of the slide 52 , making it easier for the staff to move the silo 46 and reducing labor intensity. The balls 53 are slidably mounted inside the grooves 59 .

[0057] In this embodiment, when the silo 46 descends and resets, the balls 53 at the bottom thereof enter the grooves 59 , thereby reducing the movement resistance and making it easier for subsequent staff to move the silo 46 .

[0058] Specifically, a positioning rod 54 is slidably installed through the end of the silo 46, and a second spring 55 is fixedly installed between the positioning rod 54 and the end of the silo 46 for resetting the positioning rod 54. The second spring 55 is movably sleeved on the periphery of the positioning rod 54;

[0059] A positioning groove 56 is formed on the outer side of the slide 52 , and the positioning groove 56 cooperates with the positioning rod 54 .

[0060] In this embodiment, when multiple silos 46 are used, the loading steps are the same as above, and the plastic tube replenishment method of the silo 46 is different. When the No. 1 silo 46 is raised to load the materials, the staff fills the plastic tubes into the other silos 46, and the No. 1 silo 46 is lowered and reset. The plug-in column 44 and the plug-in slot 45 are disengaged. The staff pushes the other silos 46 to remove the No. 1 silo 46 and realize the rapid replenishment of the silo 46. The end of the positioning rod 54 enters the positioning slot 56, which means that the silo 46 has reached the working position. The telescopic ends of the first cylinder 41 and the second cylinder 42 are extended, driving the plug-in column 44 to insert into the plug-in slot 45, and then continue to extend to perform the loading operation, thereby shortening the replenishment time and improving production efficiency.

[0061] Specifically, two groups of fixing frames 57 are symmetrically fixedly installed at the bottom of the slide 52 , and two limiting rods 58 are fixedly installed inside the fixing frames 57 . The two groups of limiting rods 58 are respectively arranged on the outsides of the two hinge components 43 .

[0062] In this embodiment, after the plug-in column 44 and the plug-in slot 45 are disconnected, the hinge assembly 43 is kept vertical under the limiting action of the limiting rod 58, so as to facilitate the subsequent insertion of the plug-in column 44 into the plug-in slot 45 again.

[0063] How it works:

[0064] When working with a single silo 46, the staff puts the plastic pipe into the silo 46, the telescopic ends of the first oil cylinder 41 and the second oil cylinder 42 extend synchronously, driving the silo 46 to move upward, and the silo 46 drives the baffle 413 to rotate and open, the telescopic end of the first oil cylinder 41 extends, driving the silo 46 and the push plate 47 to tilt, and the push plate 47 slides downward in sequence, pushing the plastic pipe into the feed box 3, and then into the crushing unit 2 for crushing, realizing quantitative feeding, so that the crushing unit 2 is basically in the best working state, and under the blocking effect of the plastic pipe, the movable plate 415 moves the extrusion pressure sensor The first spring 416 is compressed. When all the plastic tubes on the top layer enter the feed box 3, the pressure sensor 417 of the top layer push plate 47 is reduced, and the movable plate 415 is reset under the elastic force of the first spring 416. The pressure sensor 41 controls the extension of the telescopic end of the first oil cylinder 41 with the help of the data processor, so that the second push plate 47 pushes the plastic tubes to slide down, realizing the equal discharge of the plastic tubes. The subsequent sliding plastic tubes can push the plastic tubes remaining in the feed box 3, so that the plastic tubes are not easy to slip with the crushing rollers of the crushing unit 2;

[0065] After all the plastic pipes have fallen, the telescopic end of the first oil cylinder 41 is shortened, so that the bin 46 tilts in the opposite direction, so that all the push plates 47 slide and reset, and then the telescopic end of the second oil cylinder 42 is shortened to make the bin 46 horizontal, and the telescopic ends of the first oil cylinder 41 and the second oil cylinder 42 are shortened synchronously, so that the bin 46 descends and resets, and the staff fills the plastic pipes again. After the bin 46 moves down, the baffle 413 rotates in the opposite direction and resets under the action of gravity, which has a certain driving effect on the plastic pipes exposed at the end of the feed box 3, and can also improve the crushing efficiency of the crushing unit 2, and the baffle 413 can reduce the possibility of splashes generated by crushing flying out of the feed box 3, ensuring the production safety of the staff;

[0066] For different plastic pipes, such as those with different thicknesses and wall thicknesses, the crushing efficiency of the crushing unit 2 is different, and thus the single feed amount needs to be adjusted. The staff can use the connecting bolts 49 and the connecting plate 410 to fix and connect multiple adjacent push plates 47 to increase the single feed amount, thereby improving the flexibility of the device and adapting to more actual production environments.

[0067] When multiple silos 46 are used, the loading steps are the same as above, and the plastic tube replenishment method of the silo 46 is different. When silo No. 1 46 (i.e., the silo 46 that has just completed the loading operation) is raised to load, the staff fills plastic tubes into other silos 46. When silo No. 1 46 is lowered and reset, the ball 53 at its bottom enters the groove 59, reducing the movement resistance and facilitating the subsequent staff to move the silo 46. The plug-in column 44 and the plug-in slot 45 are disengaged, and the hinge assembly 43 remains vertical under the limiting action of the limit rod 58. The staff pushes other silos 46 to remove silo No. 1 46 and realizes rapid replenishment of the silo 46. The end of the positioning rod 54 enters the positioning slot 56, indicating that the silo 46 has reached the working position, and the telescopic ends of the first cylinder 41 and the second cylinder 42 extend, driving the plug-in column 44 to insert into the plug-in slot 45, and then continue to extend for loading operations, shortening the replenishment time and improving production efficiency.

[0068] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
