Description

Technical Field

[0001] This utility model relates to the technical field of plastic recycling equipment, specifically an automatic recycling and conveying line for plastic scraps. Background Technology

[0002] Plastic scrap refers to waste generated during the plastic production process, including cutting and molding. This waste includes burrs, runner excess, branch runner excess, flash, preform residue, and finished products. Plastic scrap is primarily generated due to excess material produced during plastic product processing caused by improper mold cutting or molding. If these scraps are not properly managed, they can cause serious environmental pollution, as plastic decomposes very slowly in the natural environment, potentially taking hundreds of years.

[0003] The recycling process of plastic scraps involves sorting and washing to remove impurities and contaminants, followed by crushing into small particles, which are then melted and reshaped to produce new plastic products. This process not only reduces the demand for new plastic raw materials but also lowers production costs and conserves resources. In existing plastic scrap recycling, automated recycling conveyor lines are crucial equipment. These lines transport plastic scraps to corresponding recycling equipment for processing, with belt conveyors being the most common type.

[0004] In actual use, the applicant found that the existing automatic recycling conveyor belts for plastic scraps have different recycling and processing requirements due to the different types, materials, and sizes of plastic scraps. However, the existing automatic recycling conveyor belts can only meet one type of processing requirement and cannot be switched according to different types of plastic scraps. This results in poor production flexibility and compatibility. Furthermore, if multiple processing lines are set up separately, it will inevitably lead to an increase in equipment, serious equipment idleness, and high investment costs.

[0005] Therefore, it is necessary to design an automatic recycling conveyor line for plastic scrap that can be switched. Utility Model Content

[0006] The purpose of this invention is to provide an automatic recycling and conveying line for plastic scraps to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic recycling conveyor line for plastic scrap, including a first conveyor for plastic scrap and several second conveyors. A rotating plate is fixedly connected to the bottom left side of the first conveyor, and a shaft column is fixedly connected to the bottom of the rotating plate. A bracket is rotatably connected to the lower part of the shaft column. An arc-shaped sliding mechanism is installed on the other side of the bottom of the first conveyor. The first conveyor rotates on the bracket via the shaft column through the arc-shaped sliding mechanism, thereby adjusting the discharge position on the right side of the first conveyor, so that the first conveyor can be connected to each of the second conveyors for use.

[0008] The arc-shaped sliding mechanism includes an arc-shaped base plate, an arc-shaped slide rail fixedly connected to the arc-shaped base plate, a slider slidably connected to the arc-shaped slide rail, a movable frame fixedly connected to the slider, the bottom right side of the first conveyor fixedly mounted on the movable frame, a self-locking stepper motor fixedly connected to the movable frame, a gear fixedly connected to the output shaft of the stepper motor, and an arc-shaped external rack fixedly connected to the arc-shaped slide rail, the arc-shaped external rack meshing with the gear.

[0009] According to the above technical solution, the centers of the arc-shaped base plate, the arc-shaped slide rail, and the arc-shaped external rack are all located on the axis of the shaft column.

[0010] According to the above technical solution, the second conveyor is arranged at equal angles on the outer side of the arc-shaped base plate with the axis of the shaft column as the center.

[0011] According to the above technical solution, both the first conveyor and the second conveyor are existing belt conveyors.

[0012] According to the above technical solution, a feeding hopper is provided on the upper left side of the first conveyor, and two L-shaped support plates are fixedly installed on the outer wall of the feeding hopper. The bottom of the L-shaped support plates is fixedly installed on the bracket.

[0013] According to the above technical solution, a concave baffle is provided at the discharge port of the feeding hopper, and the concave baffle is fixedly installed on the frame of the first conveyor.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: In use, the discharge end of the first conveyor can be driven to rotate along the axis of the shaft column through the arc sliding mechanism, thereby symmetrically connecting the discharge end of the first conveyor to the second conveyor at different positions. Then, according to the processing requirements of plastic scraps, they can be transported to the second conveyor of the corresponding processing equipment, so that the entire conveyor line can adapt to the switching of multi-product plastic scrap recycling and processing, improve the flexibility and compatibility of plastic scrap recycling and conveying, and reduce equipment investment costs by sharing the conveyor line.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2 This utility model provides a technical solution: an automatic plastic scrap recycling and conveying line, including a first conveyor 1 for plastic scrap and several second conveyors 2. A rotating plate 3 is fixedly connected to the bottom left side of the first conveyor 1, and a shaft column 4 is fixedly connected to the bottom of the rotating plate 3. A bracket 5 is rotatably connected to the lower part of the shaft column 4. An arc-shaped sliding mechanism 6 is installed on the other side of the bottom of the first conveyor 1. The first conveyor 1 rotates on the bracket 5 via the shaft column 4 through the arc-shaped sliding mechanism 6, thereby adjusting the discharge position on the right side of the first conveyor 1. This allows the first conveyor 1 to be connected with each of the second conveyors 2. In this structure, the arc-shaped sliding mechanism 6 can drive the discharge end of the first conveyor 1 to rotate along the axis of the shaft column 4, thereby symmetrically positioning the discharge end of the first conveyor 1 with the second conveyors 2 at different positions. This allows the plastic scrap to be transported to different processing equipment for processing. The entire conveyor line can adapt to the switching of multi-product plastic scrap recycling and processing, improving its applicability.

[0021] It should be noted that different discharge ports of the second conveyor can be used to process different plastic scraps, such as sorting machines, crushers, or compressors.

[0022] Please see Figure 1-2 The arc-shaped sliding mechanism 6 includes an arc-shaped base plate 61, an arc-shaped slide rail 62 fixedly connected to the arc-shaped base plate 61, a slider 63 slidably connected to the arc-shaped slide rail 62, and a movable frame 64 fixedly connected to the slider 63. The bottom right side of the first conveyor 1 is fixedly mounted on the movable frame 64. A self-locking stepper motor 65 is fixedly connected to the movable frame 64. A gear 66 is fixedly connected to the output shaft of the stepper motor 65. An arc-shaped external rack 67 is fixedly connected to the arc-shaped slide rail 62. The arc-shaped external rack 67 meshes with the gear 66. In this structure, the stepper motor 65 drives the gear 66 to rotate. The gear 66, in conjunction with the arc-shaped external rack 67, can drive the movable frame 64 to slide on the arc-shaped track 62 via the slider 63, thereby moving the discharge end of the first conveyor 1.

[0023] Please see Figure 1-2 The centers of the arc-shaped base plate 61, the arc-shaped slide rail 62, and the arc-shaped external rack 67 are all located on the axis of the shaft column 4.

[0024] Please see Figure 1-2 The second conveyor 2 is arranged at equal angles on the outside of the arc-shaped base plate 61 with the axis of the shaft column 4 as the center.

[0025] Please see Figure 1-2 Both the first conveyor 1 and the second conveyor 2 are existing belt conveyors. Belt conveyors are commonly used equipment in this technical field, and their specific structures have been disclosed. Therefore, they will not be described in detail here. The specific structure of a commonly used belt conveyor generally includes a frame, a motor, several conveyor rollers and a conveyor belt. The motor is fixed on the frame, the conveyor rollers are rotatably mounted on the frame, and the conveyor belt is wrapped around the conveyor rollers. The motor drives the conveyor rollers to rotate, thereby driving the conveyor belt to move, thus realizing the conveying of plastic scraps.

[0026] Please see Figure 1-2 A feeding hopper 7 is provided on the upper left side of the first conveyor 1. Two L-shaped support plates 8 are fixedly installed on the outer wall of the feeding hopper 7. The bottom of the L-shaped support plates 8 is fixedly installed on the bracket 5. This structure uses the feeding hopper 7 to feed the first conveyor 1.

[0027] Please see Figure 1-2 A concave baffle 9 is provided at the discharge port of the feeding hopper 7. The concave baffle 9 is fixedly installed on the frame of the first conveyor 1. In this structure, the concave baffle 9 is used to prevent plastic scraps from falling out of the first conveyor 1 when the feeding hopper 7 discharges material.

[0028] It should be noted that the control of the conveyor lines mentioned above all uses the PLC control method commonly used in this technical field. The specific equipment and control programs are technologies well known in this technical field, so they will not be described in detail here.

[0029] The implementation principle of the embodiments of the subject matter of this application is as follows:

[0030] In use, according to the recycling and processing needs of plastic scraps, the stepper motor 65 drives the gear 66 to rotate. The gear 66, in conjunction with the arc-shaped external rack 67, drives the movable frame 64 to slide on the arc-shaped track 62 via the slider 63. At this time, the feed end of the first conveyor 1 rotates on the support via the shaft 4, thereby moving the discharge end of the first conveyor 1. This connects the first conveyor 1 with the second conveyor 2 of the corresponding processing equipment, thus conveying the plastic scraps from the first conveyor 1 to the second conveyor 2. Then, the second conveyor 2 conveys the plastic scraps into the corresponding processing equipment.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
