Description

Technical Field

[0001] The invention relates to a crushing device, in particular to a crushing device for chemical plastic barrels. Background Art

[0002] In the recycling process of chemical barrels, the crushing process is a crucial link. This process is not only related to recycling efficiency, but also involves important issues such as environmental protection and resource recycling. However, existing crushing equipment often faces some challenges when processing chemical barrels. One of the most notable difficulties is the fixed tooth spacing of the crushing roller.

[0003] After use, chemical barrels often have residual chemicals or oil inside. If these residues are discarded without treatment, it will not only pollute the environment, but also waste precious resources. Therefore, recycling chemical barrels and crushing them is an important measure to achieve resource reuse and environmental protection. In the crushing process, chemical barrels need to undergo a series of physical treatments, such as extrusion, shearing and crushing, and finally be broken into small pieces for subsequent cleaning, classification and reuse. However, there is a significant problem in this process: due to the different shapes and sizes of chemical barrels, and the surface is often relatively smooth, they are prone to rolling when crushed.

[0004] In existing crushing equipment, the tooth spacing of the crushing roller is usually fixed. This design works well when processing materials with regular shapes and uniform sizes, but it is inadequate when facing materials with irregular shapes and variable sizes such as chemical barrels. Due to the fixed tooth spacing, chemical barrels are prone to rolling during the crushing process and cannot smoothly enter the gap between the crushing rollers, resulting in low crushing efficiency and even possible damage to the equipment.

[0005] Based on the problems existing in the existing crushing equipment with fixed crushing roller tooth spacing, it is urgent to design a crushing equipment with a flexible and variable crushing roller structure to achieve an efficient crushing effect on chemical plastic barrels. Summary of the invention

[0006] In order to overcome the disadvantage that the tooth spacing of the crushing roller is usually fixed, the chemical barrel is easily unable to smoothly enter the gap of the crushing roller due to rolling during the crushing process, resulting in low crushing efficiency, the technical problem to be solved is: to provide a crushing equipment for chemical plastic barrels with adjustable tooth spacing of the crushing roller.

[0007] The technical scheme of the present invention is: a crushing device for chemical plastic barrels, including a crushing bin, a spline shaft, a power assembly and a toothed disc. The crushing bin is hollow inside and is provided with an inverted cone-shaped middle partition guide plate. Two parallel spline shafts are rotatably connected in the crushing bin and are located below the partition guide plate. The power assembly located on the side of the crushing bin drives the spline shaft. The spline shaft is provided with a toothed disc. The toothed discs located on different spline shafts are staggered to achieve a crushing effect. The crushing device also includes a guide rod, a moving block, a scissor-type connecting rod, a sleeve, a connecting rod, a control screw and a pushing mechanism. The guide rod is horizontally placed in the inner cavity of the crushing bin. The moving block The sliding connection is in the guide rod, the scissor-type connecting rod is connected to the moving block, the connecting rod is connected to the end moving block, the connecting rod is slidingly connected to the side wall of the crushing bin, the control screw is rotationally connected to the side wall of the crushing bin and is threadedly connected to the connecting rod, a sleeve is fixedly connected to the bottom of the moving block, the toothed disc slides on the outside of the spline shaft through the spline limit, the toothed disc is position-limited by the sleeve, the pushing mechanism is arranged in the crushing bin and is energized by the power assembly, the pushing mechanism can continuously push the chemical plastic barrel to prevent the chemical plastic barrel from always maintaining a single crushing angle and rolling, and the middle hinge point of the scissor-type connecting rod is rotationally connected to the moving block.

[0008] As a preferred technical solution of the present invention, a ball bearing is also included. The ball bearing is arranged in the sleeve, specifically between the sleeve and the gear disc.

[0009] As a preferred technical solution of the present invention, the pushing mechanism includes a transmission shaft and a pushing seesaw, the pushing seesaw is rotatably connected to the moving block, a torsion spring is connected between the pushing seesaw and the moving block, the transmission shaft is rotatably connected to the crushing bin, the power assembly provides power to the transmission shaft, and an axial flange is provided on the outside of the transmission shaft, which can contact and push the pushing seesaw to rotate it. Since the pushing seesaw is located on the upper surface of the moving block, that is, it preferentially contacts the end face of the chemical plastic barrel, the pushing seesaw can timely adjust the crushing angle of the chemical plastic barrel entering the crushing bin. Compared with the traditional method of crushing the chemical plastic barrel only by toothed disc engagement, the device continuously swings the pushing seesaw to push the chemical plastic barrel to move disorderly, thereby avoiding the situation where the chemical plastic barrel cannot be crushed due to a single flip.

[0010] As a preferred technical solution of the present invention, it also includes an electric push rod and an extrusion bracket. The extrusion bracket is slidably connected to the top surface of the crushing bin. The electric push rod fixed on the top of the crushing bin drives the extrusion bracket to slide longitudinally. The extrusion bracket is in an arc shape with the curved surface facing upward, and the chemical plastic barrel in the crushing bin is accurately pushed through the concave surface of the extrusion bracket.

[0011] As a preferred technical solution of the present invention, it also includes a movable clamping jaw, which is rotatably connected to the end of the extrusion bracket.

[0012] As a preferred technical solution of the present invention, it also includes a turntable, an articulated push rod, a push plate and a bevel gear group. The turntable is rotatably connected in the crushing bin, and the transmission shaft transmits the power to the turntable through the bevel gear group. The push plates are arranged opposite to each other and are slidably connected to the inner wall of the crushing bin. One end of the articulated push rod is rotatably connected to the push plate, and the other end is hinged to the eccentric part of the turntable. The bevel gear group consists of two bevel gears meshing with each other, one of which is fixed at the bottom of the turntable, and the other is connected to the end of the transmission shaft through a key.

[0013] As a preferred technical solution of the present invention, it also includes a nozzle, which is rotatably connected to the inner wall of the crushing bin, and an atomizing nozzle is arranged on the nozzle, and the atomizing nozzle points to the toothed disc.

[0014] As a preferred technical solution of the present invention, it also includes a slotted connecting rod and a convex shaft. The convex shaft is fixedly connected to the eccentric part of the spline shaft end. The slotted connecting rod is fixedly connected to the nozzle end and is slidably connected to the convex shaft.

[0015] Beneficial effects: 1. By rotating the control screw to pull the connecting rod to move horizontally, the connecting rod will pull the moving block. Since the moving blocks are connected with a scissor-type connecting rod, the moving blocks will be expanded in proportion, so as to adjust the spacing between the toothed discs to reduce the situation where the chemical plastic barrels are large and cannot be crushed due to rolling. During the period when the toothed discs crush the chemical plastic barrels, the transmission shaft continues to rotate. The transmission shaft is provided with an axial flange that can continuously push the pusher plate. The pusher plate can timely adjust the crushing angle of the chemical plastic barrel entering the crushing bin, avoiding the situation where the chemical plastic barrel cannot be crushed due to a single flip, thereby improving the crushing efficiency of the chemical plastic barrels.

[0016] 2. The transmission shaft drives the turntable to rotate through the bevel gear set, and the turntable drives the push plate to move back and forth horizontally through the hinged push rod. Since the push plate is located above the moving block, the push plate that moves back and forth horizontally can push the chemical plastic barrels or chemical plastic barrel fragments that deviate from the crushing bin in a centralized manner, so that the chemical plastic barrels or chemical plastic barrel fragments can be crushed by the toothed disc.

[0017] 3. A nozzle that can swing regularly is installed in the crushing chamber. The nozzle continuously cleans the toothed disc through the atomizing nozzle to increase the service life of the toothed disc. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0028] Embodiment: A crushing device for chemical plastic barrels, such as Figure 1-Figure 8As shown, it includes a crushing chamber 1, a spline shaft 2, a power component 201 and a toothed disc 7. The crushing chamber 1 is hollow inside and is provided with an inverted cone-shaped middle partition guide plate. Two parallel spline shafts 2 are rotatably connected in the crushing chamber 1 and are located below the partition guide plate. The power component 201 located on the side of the crushing chamber 1 drives the spline shaft 2. The spline shaft 2 is provided with a toothed disc 7. The toothed discs 7 located on different spline shafts 2 are staggered to achieve a crushing effect. It also includes a guide rod 3, a moving block 4, a scissor-type connecting rod 5, a sleeve 6, a connecting rod 9, a control screw 10 and a pushing mechanism. The guide rod 3 is horizontally placed in the inner cavity of the crushing chamber 1, the moving block 4 is slidably connected in the guide rod 3, the scissor-type connecting rod 5 is connected to the moving block 4, the connecting rod 9 is connected to the end moving block 4, the connecting rod 9 is slidably connected to the side wall of the crushing chamber 1, and the control screw 10 is rotatably connected to the side wall of the crushing chamber 1 and is threadedly connected to the connecting rod 10. Rod 9, a sleeve 6 is fixedly connected to the bottom of the moving block 4, and the toothed disc 7 slides on the outside of the spline shaft 2 through a spline limiter. The toothed disc 7 is limited in position by the sleeve 6. The pushing mechanism is arranged in the crushing bin 1 and is energized by the power assembly 201. The pushing mechanism can continuously push the chemical plastic barrel to prevent the chemical plastic barrel from always maintaining a single crushing angle and rolling. The middle hinge point of the scissor-type connecting rod 5 is rotatably connected to the moving block 4. It is worth noting that the middle moving block 4 is fixedly connected to the guide rod 3. Therefore, the connecting rod 9 can be moved horizontally by rotating the control screw 10. When the connecting rod 9 moves to the left, the connecting rod 9 pulls the leftmost moving block 4, and the spacing of the left part of the moving block 4 will be proportionally stretched by the scissor-type connecting rod 5. Similarly, the right part of the moving block 4 moves synchronously, so that the spacing of the toothed disc 7 can be adjusted, and timely adjustment can be made according to chemical plastic barrels of different specifications.

[0029] like Figure 3 As shown, a ball bearing 8 is also included. The ball bearing 8 is arranged in the sleeve 6, specifically between the sleeve 6 and the toothed disc 7. The arrangement of the ball bearing 8 can effectively reduce the friction coefficient between the sleeve 6 and the toothed disc 7, improve the rotation efficiency of the toothed disc 7, and thus improve the crushing efficiency and quality.

[0030] like Figure 5As shown, the pushing mechanism includes a transmission shaft 11 and a pushing seesaw 12, the pushing seesaw 12 is rotatably connected to the moving block 4, a torsion spring is connected between the pushing seesaw 12 and the moving block 4, the transmission shaft 11 is rotatably connected to the crushing bin 1, the power assembly 201 provides power to the transmission shaft 11, and an axial flange is provided on the outside of the transmission shaft 11, which can contact and push the pushing seesaw 12 to rotate it. Since the pushing seesaw 12 is located on the upper surface of the moving block 4, that is, it preferentially contacts the end face of the chemical plastic barrel, the pushing seesaw 12 can timely adjust the crushing angle of the chemical plastic barrel entering the crushing bin 1. Compared with the traditional method of crushing the chemical plastic barrel only by engaging the toothed disc 7, the device continuously swings the pushing seesaw 12 to push the chemical plastic barrel to move disorderly, thereby avoiding the situation where the chemical plastic barrel cannot be crushed due to a single flip.

[0031] like Figure 6 As shown, it also includes an electric push rod 13 and an extrusion bracket 14. The extrusion bracket 14 is slidably connected to the top surface of the crushing bin 1. The electric push rod 13 fixed on the top of the crushing bin 1 drives the extrusion bracket 14 to slide longitudinally. The extrusion bracket 14 is in an arc shape with a curved surface facing upward. The chemical plastic barrel in the crushing bin 1 is accurately pushed through the concave surface of the extrusion bracket 14, and the chemical plastic barrel is pushed between the toothed discs 7 by active pressing, so that the crushing efficiency is maximized. The movable clamping jaw 15 is rotatably connected to the end of the extrusion bracket 14. The movable clamping jaw 15 provides a larger extrusion range, so that the extrusion bracket 14 can accurately push the chemical plastic barrel below.

[0032] like Figure 7 As shown, it also includes a rotating disk 16, an articulated push rod 17, a push plate 18 and a bevel gear set 19. The rotating disk 16 is rotatably connected in the crushing bin 1, and the transmission shaft 11 transmits the rotating disk 16 through the bevel gear set 19. The push plates 18 are arranged oppositely and slidably connected to the inner wall of the crushing bin 1. One end of the articulated push rod 17 is rotatably connected to the push plate 18, and the other end is hinged to the eccentric part of the rotating disk 16. The bevel gear set 19 is two bevel gears meshing with each other, one of which is fixed at the bottom of the rotating disk 16, and the other is connected to the end of the transmission shaft 11 through a key. The power assembly 201 continuously drives the transmission shaft 11 rotates, the transmission shaft 11 drives the turntable 16 to rotate through the bevel gear set 19, and the turntable 16 drives the push plate 18 to reciprocate horizontally through the hinged push rod 17. Since the push plate 18 is located above the moving block 4, the push plate 18 that moves horizontally reciprocatingly can push the chemical plastic barrels or chemical plastic barrel fragments that deviate from the crushing bin 1 in a centralized manner, so that the chemical plastic barrels or chemical plastic barrel fragments can be crushed by the toothed disc 7. In order to improve the horizontal movement stability of the push plate 18, two sets of the turntable 16 and the bevel gear set 19 are provided, and are correspondingly located at both ends of the push plate 18.

[0033] like Figure 8As shown, it also includes a nozzle 20, which is rotatably connected to the inner wall of the crushing bin 1. An atomizing nozzle 2001 is arranged on the nozzle 20, and the atomizing nozzle 2001 points to the toothed disc 7. A convex shaft 22 is fixedly connected to the eccentric part of the end of the spline shaft 2, and a slotted connecting rod 21 is fixedly connected to the end of the nozzle 20. The slotted connecting rod 21 is slidably connected to the convex shaft 22. The power component 201 drives the spline shaft 2 to rotate continuously, and the convex shaft 22 at the end of the spline shaft 2 will drive the slotted connecting rod 21 to swing left and right, thereby driving the nozzle 20 to swing left and right. The nozzle 20 sprays and cleans the toothed disc 7 through the atomizing nozzle 2001, thereby reducing the waste in the chemical plastic barrel from adhering to the toothed disc 7 and causing long-term corrosion damage to it.

[0034] The working principle of the embodiment of the present invention is as follows: a chemical plastic barrel is put into the crushing bin 1, and the power assembly 201 is turned on. The power assembly 201 is composed of a motor and a gear set. The gear set is composed of three gears that mesh one by one, one of which is connected to the motor output shaft, and the other two gears are fixed to the ends of the spline shaft 2. After the motor is turned on, the spline shaft 2 rotates in opposite directions, and then the chemical plastic barrel is crushed through the toothed disc 7. If the chemical plastic barrel is large in size, the spacing of the toothed disc 7 needs to be increased, and the control screw 10 can be rotated. A rotating wheel is set at the left end of the control screw 10 for the convenience of the staff to hold it. The control screw 10 rotates After the movement, the connecting rod 9 can be driven to move to the left, and the connecting rod 9 will pull the leftmost moving block 4 to move to the left, and the moving block 4 will be proportionally expanded through the scissor-type connecting rod 5, thereby increasing the distance between adjacent toothed discs 7 to adapt to chemical plastic barrels with larger specifications. During the crushing of the chemical plastic barrel by the toothed disc 7, the power component 201 simultaneously drives the transmission shaft 11 to rotate through the gear. The transmission shaft 11 is provided with an axial flange that can continuously push the pusher seesaw 12. Since the pusher seesaw 12 is located on the upper surface of the moving block 4, that is, it preferentially contacts the end face of the chemical plastic barrel, the pusher seesaw 12 can be adjusted in time. The crushing angle of the chemical plastic barrel entering the crushing bin 1 is different from the traditional method of crushing the chemical plastic barrel only by meshing the toothed disc 7. The device continuously swings the pushing seesaw 12 to push the chemical plastic barrel to move disorderly, avoiding the situation that the chemical plastic barrel cannot be crushed due to a single flip. In order to improve the crushing efficiency of the chemical plastic barrel, an extrusion bracket 14 powered by an electric push rod 13 is provided. The extrusion bracket 14 can actively push the chemical plastic barrel, improve the crushing speed and efficiency of the chemical plastic barrel between the toothed discs 7, and further avoid the flipping of the chemical plastic barrel. 11 drives the turntable 16 to rotate through the bevel gear set 19, and the turntable 16 drives the push plate 18 to reciprocate horizontally through the hinged push rod 17. Since the push plate 18 is located above the moving block 4, the push plate 18 that moves horizontally reciprocatingly can push the chemical plastic barrels or chemical plastic barrel fragments that deviate from the crushing bin 1 in a centralized manner, so that the chemical plastic barrels or chemical plastic barrel fragments can all be crushed by the toothed disc 7. Finally, a nozzle 20 that can swing regularly is provided in the crushing bin 1. The nozzle 20 continuously cleans the toothed disc 7 through the atomizing nozzle 2001, thereby increasing the service life of the toothed disc 7.

[0035] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
