Description

Technical Field

[0001] This utility model relates to the field of plastic particle production technology, and in particular to a transport mechanism for modified plastic particles. Background Technology

[0002] Modified plastics refer to plastic products that have been processed through methods such as filling, blending, and reinforcement on the basis of general-purpose plastics and engineering plastics, thereby improving their properties such as flame retardancy, strength, impact resistance, and toughness. Generally, plastic particles need to be packed into boxes and then transported through transfer boxes during transportation.

[0003] A search revealed a Chinese patent (authorization announcement number CN214607626U) disclosing a transport device for modified plastic particles, comprising a hinged base, a shock-absorbing mechanism, and a lifting mechanism. The shock-absorbing mechanism includes a housing A, a piston cylinder, a piston rod, a caster wheel, a first shock-absorbing spring, a cavity box, a second shock-absorbing spring, a slider, a push rod, a baffle, and a third shock-absorbing spring. The bottom of the hinged base is fixedly connected to the top of the piston cylinder, and the top of the piston rod is movably connected to the piston cylinder. This patented technology achieves shock absorption by incorporating a shock-absorbing mechanism, housing A, piston cylinder, piston rod, caster wheel, first shock-absorbing spring, cavity box, second shock-absorbing spring, slider, push rod, baffle, third shock-absorbing spring, and pull rod. This solves the problem that in some production plants, plastic particles often scatter on the ground during transport due to uneven road surfaces, causing vibrations, shaking, or even overturning.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that the above-mentioned transport device uses a handle to make the threaded rod drive the lifting plate to move upward so that the staff can pick up the plastic particle boxes. However, this method requires manual operation by the staff, which is time-consuming, labor-intensive and inefficient. In addition, the plastic particle boxes on the lifting plate are not fixed, which can easily cause the boxes to fall off the lifting plate. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the main objective of this utility model is to provide a transport mechanism for modified plastic particles.

[0006] The technical solution of this utility model is as follows: a transport mechanism for modified plastic particles includes a base plate, a transport box fixedly connected to the top of the base plate, a lifting plate slidably installed on the inner wall of the transport box, two movable seats slidably connected to the inner wall of the transport box and below the lifting plate, a bidirectional lead screw rotatably connected inside the transport box, the two movable seats being threaded to the two ends of the outer side of the bidirectional lead screw, a fixed rod fixedly connected inside the transport box, the movable seats being slidably connected to the outer side of the fixed rod, a second connecting rod rotatably connected to the two ends of the top of each movable seat, the end of the second connecting rod away from the movable seat being rotatably connected to the bottom of the lifting plate, and the movable seats being slidably connected to the inner wall of the transport box.

[0007] By adopting the above technical solution, the rotation of the bidirectional lead screw drives the movement of two moving seats, causing the two moving seats to move in opposite directions. This allows the height of the lifting plate to be raised with the help of the second connecting rod, and works in conjunction with the servo motor, eliminating the need for manual operation.

[0008] In a preferred embodiment, the lifting plate is provided with a clamping assembly, which includes mounting slots at both ends inside the lifting plate. Two limiting rods are fixedly connected inside each mounting slot, and an L-shaped clamping plate is slidably installed between the two limiting rods.

[0009] By adopting the above technical solution and setting the limiting rod, the L-shaped clamping plate can be made more stable during movement and less prone to shaking.

[0010] In a preferred embodiment, the clamping assembly further includes a second servo motor fixedly installed at the bottom of the lifting plate. A rotating component is fixedly connected to the output shaft of the second servo motor. First connecting rods are rotatably installed at both ends of the outer side of the rotating component. The ends of the first connecting rods away from the rotating component are rotatably connected to the corresponding L-shaped clamping plates.

[0011] By adopting the above technical solution, the rotation of the output shaft of the second servo motor can drive the rotating component to rotate, thereby enabling the first connecting rod to pull the L-shaped clamping plate.

[0012] In a preferred embodiment, a servo motor is fixedly mounted on the outer side of the base plate, and the output shaft of the servo motor extends into the interior of the transport box and is fixedly connected to a bidirectional lead screw.

[0013] By adopting the above technical solution, the rotation of the output shaft of the servo motor can drive the moving seat to move, thereby realizing the transmission of power.

[0014] In a preferred embodiment, casters are rotatably mounted at all four corners of the bottom of the base plate, and a pair of handles are fixedly connected to one end of the top of the base plate.

[0015] By adopting the above technical solution, and by setting up casters and handles, the entire base plate can be moved and used easily.

[0016] In a preferred embodiment, the L-shaped clamping plate is slidably connected to the inner wall of the mounting groove.

[0017] By adopting the above technical solution, the movement can be made more stable.

[0018] In a preferred embodiment, a controller is provided on the outer side of the base plate, and both servo motor one and servo motor two are electrically connected to the controller.

[0019] By adopting the above technical solution, the controller can be used to control servo motor one and servo motor two.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, when it is necessary to remove the plastic particle package from the transport box, the drive source of the control bidirectional screw can be turned on. The rotation of the bidirectional screw drives the movement of the two moving seats, so that the two moving seats move in opposite directions. In this way, the height of the lifting plate can be raised by means of the second connecting rod. It works in conjunction with the servo motor. During this process, no manual operation is required, which saves time and effort and improves work efficiency.

[0022] 2. In this utility model, the rotation of the output shaft of the servo motor can drive the rotating component to rotate, thereby using the first connecting rod to pull the L-shaped clamping plate, thus achieving the purpose of clamping and fixing plastic particle boxes of different sizes, thereby preventing the plastic particle boxes from falling off during transportation and improving the stability of box transportation.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] Reference Figure 1-3 A modified plastic particle transport mechanism includes a base plate 1, a transport box 2 fixedly connected to the top of the base plate 1, a lifting plate 4 slidably mounted on the inner wall of the transport box 2, two movable seats 13 slidably connected to the inner wall of the transport box 2 and below the lifting plate 4, a bidirectional lead screw 11 rotatably connected inside the transport box 2, and the two movable seats 13 respectively threaded to the two ends of the outer side of the bidirectional lead screw 11. A fixed rod 12 is fixedly connected inside the transport box 2, and the movable seats 13 are slidably connected to the outer side of the fixed rod 12. A second connecting rod 14 is rotatably connected to both ends of the top of each movable seat 13. The end of the second link 14 furthest from the movable seat 13 is rotatably connected to the bottom of the lifting plate 4. The movable seats 13 are slidably connected to the inner wall of the transport box 2. When it is necessary to take out the plastic particle package in the transport box 2, the drive source of the control double-acting screw 11 can be turned on. Through the rotation of the double-acting screw 11, the two movable seats 13 are driven to move, so that the two movable seats 13 move towards each other. In this way, the height of the lifting plate 4 can be raised by means of the second link 14. It works in conjunction with the servo motor 3. During this process, no manual operation is required, which saves time and effort and improves work efficiency.

[0029] Specifically, the lifting plate 4 is internally equipped with a clamping assembly, which includes mounting slots 5 at both ends of the lifting plate 4. Two limiting rods 6 are fixedly connected inside each mounting slot 5. The limiting rods 6 ensure greater stability of the L-shaped clamping plate 7 during movement, preventing wobbling. The L-shaped clamping plate 7 is slidably mounted between the two limiting rods 6. The clamping assembly also includes a servo motor 9 fixedly mounted at the bottom of the lifting plate 4. The rotation of the output shaft of the servo motor 9 drives the rotating component 8 to rotate, thereby enabling the first connecting rod 10 to pull the L-shaped clamping plate 7, thus facilitating the clamping of plastic granules of different sizes. The purpose of clamping and fixing the sub-boxes is to prevent the plastic particle boxes from falling during transportation and improve the stability of box transportation. A rotating part 8 is fixedly connected to the output shaft of the servo motor 2 9. The two ends of the outer side of the rotating part 8 are rotatably mounted with the first connecting rod 10. The end of the first connecting rod 10 away from the rotating part 8 is rotatably connected to the corresponding L-shaped clamping plate 7. A servo motor 1 3 is fixedly mounted on the outer side of the base plate 1. The rotation of the output shaft of the servo motor 1 3 can drive the moving seat 13 to move, thereby realizing the transmission of power. The output shaft of the servo motor 1 3 extends into the interior of the transport box 2 and is fixedly connected to the bidirectional lead screw 11.

[0030] Specifically, universal wheels 15 are rotatably installed at the four corners of the bottom of the base plate 1, and a pair of handles are fixedly connected to one end of the top of the base plate 1. The universal wheels 15 and handles facilitate the movement and use of the entire base plate 1. The L-shaped clamping plate 7 is slidably connected to the inner wall of the mounting groove 5. A controller is provided on the outside of the base plate 1. Servo motor 1 3 and servo motor 2 9 are electrically connected to the controller. The controller can control servo motor 1 3 and servo motor 2 9.

[0031] Working principle: First, the controller starts the second servo motor 9. The rotation of the output shaft of the second servo motor 9 drives the rotating part 8 to rotate, which in turn allows the first connecting rod 10 to pull the L-shaped clamping plate 7 and place the plastic particle boxes to be transported between the two L-shaped clamping plates 7. This achieves the purpose of clamping and fixing plastic particle boxes of different sizes. When it is necessary to remove the plastic particle boxes from the transport box 2, the first servo motor 3 can be turned on. The rotation of the bidirectional lead screw 11 drives the two moving seats 13 to move in opposite directions. This allows the second connecting rod 14 to raise the height of the lifting plate 4. In conjunction with the first servo motor 3, no manual operation is required, saving time and effort. The universal wheels 15 and handles facilitate the movement and use of the entire base plate 1.
