Description

Technical Field

[0001] This utility model relates to the field of plastic pipe production equipment, and in particular to a raw material screening device for packaging plastic pipes. Background Technology

[0002] With the development of the plastics processing industry, encapsulated plastic pipes, due to their advantages such as light weight and corrosion resistance, are widely used in food packaging, medical devices, and other fields. The market demands increasingly higher dimensional accuracy and mechanical properties, and the quality of raw plastic granules is a key influencing factor. Plastic granules are prone to contamination with impurities during production, storage, and transportation, and fluctuations in the granulation process can lead to uneven particle size. Direct use in extrusion molding can easily cause screw wear, mold blockage, pipe defects, and even production interruptions. Therefore, a screening process is essential. While existing multi-layer screening devices can meet basic requirements, they are mostly integrated structures with insufficient maintenance and adaptability, making them difficult to match with efficient production schedules.

[0003] The core drawback of existing technology is that the multi-layer screening screens in current screening devices are mostly installed using bolts, clips, or other fixing methods. Disassembly requires loosening each connector individually, which is cumbersome and time-consuming. Cleaning clogged meshes or changing to screens of different mesh sizes requires a long downtime, severely affecting production continuity and increasing labor costs and equipment idle time. Utility Model Content

[0004] The purpose of this utility model is to provide a raw material screening device for encapsulated plastic tubes, which aims to solve the problem that the above-mentioned technical problems require a long downtime when loosening the connecting parts one by one, cleaning the blocked mesh, or changing the screen with different mesh size, which seriously affects the continuity of production, increases the labor operation cost and equipment idle rate.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A raw material screening device for encapsulating plastic tubes, comprising:

[0007] The bracket is equipped with leveling feet;

[0008] A sieve box is installed on the upper side of the bracket;

[0010] A snap-fit ​​feed tube is provided on the upper side of the flow regulating baffle;

[0011] A conical storage bin is installed on the upper side of the snap-fit ​​guide pipe.

[0012] This utility model also has the following technical features:

[0013] In one embodiment of this utility model, a spring shock-absorbing pad is installed at the connection between the bracket and the sieve box.

[0014] In one embodiment of this utility model, a vibration motor is installed on the outside of the sieve box.

[0015] In one embodiment of this utility model, three sets of guide rails are installed on the inner wall of the screen box, and a multi-layer quick-release screening screen is installed on the outer side of the guide rails. A disassembly and assembly auxiliary handle is installed on the outer side of the multi-layer quick-release screening screen.

[0016] In one embodiment of this utility model, a snap-on screen edge strip is installed between the multi-layer quick-release screen and the screen box.

[0017] In one embodiment of this utility model, three sets of reduction motors are installed on the outer side of the screen box corresponding to the gaps of the multi-layer quick-release screening mesh. A telescopic rod is installed on the outer side of the reduction motor, and an elastic rubber scraper is installed on the upper side of the telescopic rod.

[0018] In one embodiment of this utility model, a drawer-type dust collection box is installed on the lower side of the sieve box.

[0019] In one embodiment of this utility model, three sets of inclined discharge chutes are installed on the outer side of the screen box corresponding to the multi-layer quick-release screening mesh, and a collection bucket is installed on the lower side of the inclined discharge chutes.

[0020] Compared with existing technologies, the beneficial effects of this utility model are reflected in the following: A spring-loaded shock-absorbing pad is installed between the support and the screen box, which can buffer the vibration force during the operation of the vibrating motor, reduce component wear, and thus improve the operational stability of the device. A vibrating motor is installed on the outside of the screen box, providing continuous vibration force, accelerating raw material screening, and ensuring screening efficiency. A guide rail is installed on the inner wall of the screen box, combined with a multi-layer quick-release screening mesh and a disassembly / removal auxiliary handle, enabling rapid screen pulling and simplifying the disassembly / removal process, solving the problem of cumbersome traditional screen disassembly. A snap-fit ​​screen edge strip is installed between the multi-layer quick-release screening mesh and the screen box, which can fix the screen position, prevent displacement during screening, and ensure screening effect. A geared motor, telescopic rod, and elastic rubber scraper are installed on the outside of the screen box, which can automatically clean screen hole blockages, maintain smooth screening, and reduce manual cleaning costs. A drawer-type dust collection box is installed at the bottom of the screen box, which can collect fine dust centrally, avoid pollution, and maintain a clean working environment. The outside of the screen box is equipped with an inclined discharge chute and a collection bucket, which can classify and collect raw materials of different particle sizes, making them convenient for subsequent use and improving the convenience of raw material utilization.

[0031] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0032] The illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0033] It should be noted that the core defect of an existing raw material screening device for packaged plastic pipes is that a long downtime is required when loosening the connectors one by one, cleaning the clogged mesh, or changing to a different mesh size screen, which seriously affects the continuity of production, increases labor costs, and increases equipment idle rate. To address this issue, a raw material screening device for packaged plastic pipes is proposed, comprising a support 10 with leveling feet; a screen box 20 installed on the upper side of the support 10; a flow regulating baffle 30 installed on the upper side of the screen box 20; a snap-fit ​​guide pipe 40 located on the upper side of the flow regulating baffle 30; and a conical storage bin 50 installed on the upper side of the snap-fit ​​guide pipe 40.

[0034] In one embodiment, a spring damping pad 11 is installed at the connection between the support 10 and the screen box 20. The elastic buffering characteristics of the spring damping pad 11 are used to absorb the vibration force generated when the screen box 20 is working, so as to avoid the vibration force being directly transmitted to the support 10 and causing the whole device to shake. At the same time, it reduces the wear of the components at the connection between the support 10 and the screen box 20 and enhances the operational stability of the device.

[0035] In one embodiment, a vibration motor 21 is installed on the outside of the screen box 20. After the vibration motor 21 is powered on, it generates a continuous and stable vibration force and transmits it to the inside of the screen box 20, driving the multi-layer quick-release screen 23 to vibrate synchronously, which promotes the rapid dispersion and flow of plastic raw materials on the screen, accelerates the passage of raw materials that meet the particle size requirements through the screen holes, and improves screening efficiency and screening effect.

[0036] In one embodiment, the inner wall of the screen box 20 is equipped with three sets of guide rails 22, and the outer side of the guide rails 22 is equipped with a multi-layer quick-release screen 23. The outer side of the multi-layer quick-release screen 23 is equipped with a disassembly and assembly auxiliary handle 24.

[0037] In one embodiment, a snap-on screen edge strip 25 is installed between the multi-layer quick-release screen 23 and the screen box 20.

[0038] In one embodiment, three sets of geared motors 60 are installed on the outer side of the screen box 20 corresponding to the gaps of the multi-layer quick-release screen 23. A telescopic rod 61 is installed on the outer side of the geared motor 60, and an elastic rubber scraper 62 is installed on the upper side of the telescopic rod 61. The geared motor 60 drives the telescopic rod 61 to extend and retract, which drives the elastic rubber scraper 62 to move back and forth along the surface of the multi-layer quick-release screen 23. By utilizing the flexible contact characteristics of the rubber scraper, the raw material particles that are blocked in the screen holes are effectively cleaned without damaging the screen, thus maintaining the screen unobstructed and reducing the amount of manual cleaning work.

[0039] In one embodiment, a drawer-type dust collection box 26 is installed on the lower side of the sieve box 20.

[0040] In one embodiment, three sets of inclined discharge chutes 27 are installed on the outer side of the screen box 20 corresponding to the multi-layer quick-release screen 23. A collection bucket 28 is installed on the lower side of the inclined discharge chutes 27. Raw materials of different particle sizes after being screened by the multi-layer quick-release screen 23 will fall into the corresponding inclined discharge chutes 27 respectively. The inclined angle of the chutes enables the raw materials to slide naturally and finally be collected into the collection bucket 28 below, realizing the classification and collection of raw materials of different specifications, which is convenient for subsequent use as needed.

[0041] In one embodiment, see Figure 1 and Figure 2The guide rails 22, in conjunction with the multi-layer quick-release screening mesh 23, provide basic guiding support for fixing the screening mesh. The three sets of guide rails 22 on the inner wall of the screen box 20 define the installation path of the multi-layer quick-release screening mesh 23, enabling the screening mesh to be accurately pushed into the installation position along the guide rails, avoiding misalignment during installation. This lays a stable foundation for subsequent fixing procedures from the initial installation stage. At the same time, the disassembly and assembly auxiliary handles 24 facilitate operators to accurately control the movement of the screening mesh along the guide rails, ensuring that it smoothly reaches the position to be fixed.

[0042] In one embodiment, the snap-fit ​​screen edge clamping strip 25, based on the guide rail 22, achieves the final fastening of the multi-layer quick-release screen 23. After the multi-layer quick-release screen 23 is installed in place along the guide rail 22, the snap-fit ​​screen edge clamping strip 25 tightly engages the edge of the screen with the inner wall of the screen box 20, forming a mechanical fixing constraint. This effectively counteracts the impact of the vibration force generated by the vibrating motor 21 on the screen, preventing the screen from loosening or shifting during operation.

[0043] In another embodiment, see Figure 3 The drawer-type dust collection box 26, through its assembly with the screen box 20 and the structural cooperation of the multi-layer quick-release screening screen 23, indirectly assists in the stability of the overall device. The drawer-type dust collection box 26 is installed on the lower side of the screen box 20, and its assembly structure forms a reliable connection with the screen box 20. It also catches the dust falling through the multi-layer quick-release screening screen 23, preventing dust accumulation that could lead to uneven stress on the screening screen and affect its stability. Furthermore, the drawer-type design facilitates regular cleaning, ensuring that the screening screen is always in a stable working state.

[0044] In summary, the raw material screening device for encapsulated plastic tubes of this utility model can efficiently complete the grading and screening of raw materials and screen cleaning through the synergistic action of the vibrating motor 21, the multi-layer quick-release screening screen 23, the reduction motor 60 and the elastic rubber scraper 62, thus realizing the continuous and convenient functions of plastic raw material pretreatment.
