Description

Technical Field

[0001] The utility model relates to the field of plastic processing equipment, in particular to a crushing, suction and injection molding integrated system. Background Technique

[0002] In the plastic processing industry, crushers, suction machines and injection molding machines are the three indispensable core equipment, jointly promoting the efficient conversion process from waste plastics to plastic products such as plastic bottles. The crusher uses a high-speed rotating blade and an air flow assistance system to efficiently and finely crush waste plastics, converting them into small particles with uniform particle size, providing convenience for subsequent processing. The suction machine forms a negative pressure by extracting air in the hopper, automatically sucking plastic particles from the storage barrel and transporting them into the heating barrel of the injection molding machine. The injection molding machine injects the molten plastic into the mold, and after cooling and solidification, the required plastic products are formed.

[0003] There already exists an injection molding integrated system that combines a crusher, a suction machine and an injection molding machine on the market. The working process is roughly as follows: First, waste plastics are processed by the crusher and converted into small particles; then, the suction machine starts, and through the action of negative pressure, sucks the plastic particles from the storage container and transports them into the heating barrel of the injection molding machine; finally, the injection molding machine injects the molten plastic into the mold to complete the production of plastic products.

[0004] In the crushing link, due to the different shapes and sizes of plastic waste, some waste is easy to accumulate in the crushing chamber to form columns or get stuck between the blades, resulting in a reduction in crushing efficiency or even equipment failure. It is also easy to get stuck during transmission in the pipeline, and workers need to regularly use tools to push the material for feeding, affecting the continuity and stability of the production line. Content of the Utility Model

[0005] In order to overcome the shortcoming of poor stability in crushing and feeding, the utility model provides a crushing, suction and injection molding integrated system with stable crushing process.

[0006] The crushing, suction and injection molding integrated system includes an injection molding machine, a suction machine, a crusher, a support barrel, a feed inlet, a cylinder, a pressing frame and a feeding component. The suction machine is connected to the crusher and is used to extract the plastic particles crushed by the crusher. The injection molding machine is connected to the suction machine and is used to melt the plastic particles and complete the production of plastic products. A support barrel is connected to the crusher, a cylinder is installed on the support barrel, a pressing frame is connected to the piston rod of the cylinder, the pressing frame is slidably connected in the support barrel, a feed inlet is opened at the front end of the support barrel, and a feeding component is arranged at the front end of the crusher. The feeding component is connected to the feed inlet and is used to assist in feeding.

[0007] Optionally, the blanking assembly includes a support frame, a feed pipe, a feed hopper, a servo motor, and a lever. The support frame is connected to the front end of the crusher. A feed pipe is connected to the support frame. The feed pipe is connected to the support barrel. A feed hopper is connected to the feed pipe. A servo motor is installed at the bottom middle of the feed pipe. A lever is connected to the output shaft of the servo motor. The lever passes through the bottom of the feed pipe and is slidably connected to the feed pipe. The lower end of the channel of the feed pipe communicates with the feed port.

[0008] Optionally, it further includes a baffle. The pressing frame is surrounded by baffles. The baffles are slidably connected to the support barrel, and the height of the baffles is greater than the height of the feed port.

[0009] Optionally, it further includes a filter screen. A filter screen is connected to the bottom of the feed pipe and is located below the feed hopper.

[0010] Optionally, it further includes a cover plate. A cover plate is connected to the feed hopper. When the equipment is idle, the cover plate closes the top opening of the feed hopper to prevent foreign objects from entering.

[0011] Optionally, it further includes an observation window. A transparent observation window is provided on the side of the feed pipe to directly observe the blanking process of waste plastics in the feed pipe.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. By driving the pressing frame to slide up and down by the cylinder, the function of automatically pushing waste plastics into the crusher is realized, effectively solving the blockage problem caused by the mutual support of waste materials and not being able to go down during the crushing process, and improving the crushing efficiency and the stability of the equipment.

[0014] 2. By driving the lever to rotate by the servo motor, the waste plastics in the feed pipe are assisted to move downward, avoiding the stagnation phenomenon during the feeding process, and enhancing the smoothness and continuity of the blanking. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0019] To make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present utility model are only based on the accompanying drawings of the present utility model, and they do not specifically limit the present utility model.

[0020] Embodiment: A crushing, suction and injection integrated system, as Figures 1 - 3 shown, includes an injection molding machine 1, a material suction machine 2, a crusher 3, a support barrel 4, a feed inlet 5, a cylinder 6, a pressing frame 7 and a blanking assembly. The material suction machine 2 is connected to the crusher 3 through a conveying pipeline for extracting the plastic particles crushed by the crusher 3. The injection molding machine 1 is connected to the material suction machine 2 through a conveying pipeline for melting the plastic particles and completing the production of plastic products. A support barrel 4 is connected to the crusher 3, a cylinder 6 is installed on the support barrel 4, the piston rod of the cylinder 6 faces downward and is connected to a pressing frame 7. The pressing frame 7 is slidably connected to the inside of the support barrel 4. A feed inlet 5 is opened at the front end of the support barrel 4. A blanking assembly is arranged at the front end of the crusher 3. The blanking assembly is communicated with the feed inlet 5 for assisting in blanking.

[0021] The injection molding machine 1, the material suction machine 2 and the crusher 3 are in an open state. After the waste plastic passes through the blanking assembly, it falls onto the crusher 3 through the feed inlet 5 and is directly crushed by the crusher 3. Subsequently, the material suction machine 2 sucks the crushed plastic particles from the crusher 3 and transports them into the heating barrel of the injection molding machine 1. The injection molding machine 1 quantitatively injects the melted plastic into the mold. After cooling and solidifying, the required plastic products are formed and automatic discharging is completed. At the same time, the cylinder 6 also remains in an open state. The cylinder 6 pushes the pressing frame 7 to slide downward, and the pressing frame 7 pushes the waste plastic on the crusher 3, pushing the cylindrical or mutually supported and suspended waste plastic into the crusher 3 to ensure the smooth progress of the crushing process.

[0022] As Figure 1 and Figure 3 shown, the blanking assembly includes a support frame 8, a feed pipe 9, a feed hopper 10, a servo motor 11 and a dial rod 12. The support frame 8 is connected to the front end of the crusher 3. A feed pipe 9 is connected to the support frame 8. The feed pipe 9 is connected to the support barrel 4. A feed hopper 10 is connected to the feed pipe 9. A servo motor 11 is installed at the bottom middle of the feed pipe 9. A dial rod 12 is connected to the output shaft of the servo motor 11. The dial rod 12 passes through the bottom of the feed pipe 9 and is slidably connected to the feed pipe 9. The lower end of the channel of the feed pipe 9 is communicated with the feed inlet 5.

[0023] After pouring the waste plastic into the feed hopper 10, the waste plastic moves downward along the feed pipe 9. When passing through the lever 12, the activated servo motor 11 drives the lever 12 to rotate towards the feed port 5, thereby pushing the waste plastic in the feed pipe 9 downward and solving the problem of blockage of the waste plastic in the middle.

[0024] As Figure 2 shown, it further includes a baffle 14. The pressing frame 7 is connected with the baffle 14 around it. The baffle 14 is slidably connected with the support barrel 4, and the height of the baffle 14 is greater than that of the feed port 5.

[0025] The baffle 14 can partition the waste plastic near the feed port 5 when the pressing frame 7 descends, thereby preventing the waste plastic from falling onto the pressing frame 7.

[0026] As Figure 3 shown, it further includes a filter screen 13. The bottom of the feed pipe 9 is connected with a filter screen 13, which is located below the feed hopper 10.

[0027] The filter screen 13 can filter out the tiny impurities in the waste plastic that are difficult to pick out by the naked eye, ensuring the purity of the plastic particles and thus the quality of the plastic products.

[0028] As Figure 1 shown, it further includes a cover plate 15. The feed hopper 10 is connected with a cover plate 15. When the equipment is idle, the cover plate 15 closes the top opening of the feed hopper 10 to prevent foreign objects from entering.

[0029] As Figure 1 shown, it further includes an observation window 16. A transparent observation window 16 is arranged on the side of the feed pipe 9 for directly observing the feeding process of the waste plastic in the feed pipe 9.

[0030] The injection molding machine 1, the suction machine 2 and the crusher 3 work together. The injection molding machine 1 is responsible for melting and molding the plastic. The suction machine 2 sucks and transports the plastic particles crushed in the crusher 3 to the injection molding machine 1 through negative pressure. As the core processing unit, the crusher 3 realizes automatic pressing control through the cylinder 6 in the support barrel 4 connected to it and the pressing frame 7, and pushes the waste plastic that may be stuck into the crusher 3. The waste plastic enters through the feed hopper 10 of the feeding assembly and is assisted by the lever 12 driven by the servo motor 11 to ensure smooth passage of the plastic through the feed pipe 9. During this process, impurities are filtered out by the filter screen 13. At the same time, the pressing frame 7 slides downward regularly under the push of the cylinder 6, and the baffle 14 effectively blocks the waste plastic at the feed port 5 to prevent the waste plastic from falling onto the pressing frame 7. The observation window 16 arranged on the side of the feed pipe 9 is convenient for real-time monitoring of the feeding situation, while the cover plate 15 closes the feed hopper 10 when the equipment is idle to prevent foreign objects from entering.

[0031] Although the present utility model has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made to the present utility model without departing from the principles and spirit scope defined by the claims. Therefore, the detailed description of the embodiments of this disclosure is only for explanation and not for limiting the present utility model, but the scope of protection is defined by the content of the claims.
