Description

Technical Field

[0001] This utility model relates to the field of polymer material production technology, and more specifically, to a vibrating screen for polymer materials. Background Technology

[0002] The vibrating screen for polymer materials is a widely used screening equipment in industries such as polymer materials, plastics, rubber, chemicals, and food. It is mainly used for the effective screening, grading, and filtering of granular, powdered, and particulate materials. Its working principle is based on the vibration of the screen mesh. Through the action of the vibrating screen mesh, materials of different particle sizes are separated. The vibrating screen for polymer materials usually uses one or more vibration sources, such as motors or vibrators, to make the screen mesh vibrate periodically. When materials pass through the screen mesh, smaller particles can pass through the screen mesh, while larger particles are blocked on the screen mesh surface. By adjusting the vibration frequency, amplitude, and tilt angle of the screen mesh, the separation of materials of different particle sizes can be achieved. Since polymer materials have a certain degree of fluidity during vibrating screening, it is necessary to perform screening and homogenization operations on the polymer materials.

[0003] In related technologies, during the use of vibrating screens, polymer materials are generally poured directly onto the top of the vibrating screen mesh, allowing the vibrating screen mesh to vibrate and screen the polymer materials for use.

[0004] However, during the current use of vibrating screens, due to the certain inclination of the vibrating screen mesh during operation, and the downward movement of polymer materials after contact with the vibrating screen mesh, when the material is poured to the top of the vibrating screen mesh, it is very easy for the material at the top of the vibrating screen mesh to be in contact with the vibrating screen mesh. After screening, it moves out of the vibrating screen mesh range, resulting in uneven screening of polymer materials, which affects the screening uniformity and screening effect of the vibrating screen.

A leveling fixing mechanism is fixedly connected to the right side of the top of the leveling frame 4 and the leveling frame 5, respectively. According to the screening width of the screen 3, the leveling frame 5 and the leveling frame 4 are moved to both sides by hand to adjust the leveling range of the leveling frame 5 and the leveling frame 4. At this time, the connecting column 7 moves with the leveling frame 5 inside the connecting groove 6 to connect the leveling frame 4 and the leveling frame 5, so that the leveling frame 5 and the leveling frame 4 are aligned with the screen 3. A low-barrier equalization medium is formed at the top to perform equalization of the polymer material screened by the screen 3. The equalization fixing mechanism includes a fixing seat 8, a fixing rod 9, a fixing frame 10, and a fixing plate 11. The fixing seat 8 is fixedly connected to the right side of the top of the equalization frame 4 and the equalization box 5.

This avoids difficulties in installing and fixing the equalization frame 4 and the equalization box 5 during use, thus improving the convenience of installation and fixing of the equalization frame 4 and the equalization box 5.

[0032] Reference Figures 2-3In a preferred embodiment, a screw hole 12 is provided on the right side of the fixing frame 10, and a stud 13 is threadedly connected inside the screw hole 12. The left side of the stud 13 is connected to the right side of the fixing plate 11, which can provide a medium for applying a fixing force to the fixing plate 11, avoiding the situation where it is difficult to apply force to fix the fixing plate 11 during use. Therefore, the convenience of applying force to fix the fixing plate 11 is improved. A rotating groove 14 is provided on the right side of the fixing plate 11, and a rotating seat 15 is movably connected inside the rotating groove 14. The right side of the rotating seat 15 is fixedly connected to the left side of the stud 13, which can rotate the stud 13 and the fixing plate 11 to perform a rotating connection, thus improving the connection effect between the stud 13 and the fixing plate 11.

[0033] Reference Figures 2-4 In a preferred embodiment, a lifting groove 16 is provided on the right side of the fixed rod 9, and a lifting seat 17 is movably connected inside the lifting groove 16. The right side of the lifting seat 17 is fixedly connected to the left side of the fixed frame 10, which can perform lifting connection and guidance work between the fixed frame 10 and the fixed rod 9, thus improving the connection effect between the fixed frame 10 and the fixed rod 9.

[0034] Reference Figures 2-4 In a preferred embodiment, by providing a positioning groove 20 on the inner side of the fixed base 8, and the outer side of the positioning post 19 being located inside the positioning groove 20, space can be provided for the positioning post 19 to be inserted and positioned, thus improving the positioning effect of the positioning post 19. A magnetic plate 21 is embedded and connected to the bottom of the inner wall of the positioning cylinder 18, and a magnetic suction plate 22 that is magnetically connected to the magnetic plate 21 is embedded and connected to the bottom of the positioning post 19, so that the positioning post 19 and the positioning cylinder 18 can be magnetically positioned, thus improving the positioning stability of the positioning post 19.

[0035] Specifically, the working process or principle of this vibrating screen for polymer materials is as follows: During use, the equalizing frame 4 and equalizing frame 5 are moved to the top of the screen 3, and the fixing frame 10 is positioned on the outer side of the top of the screen box 2, preparing for subsequent fixing with the fixing plate 11. Based on the screening width of the screen 3, the equalizing frame 5 and equalizing frame 4 are moved to both sides to adjust their range. At this time, the connecting column 7 moves with the equalizing frame 5 inside the connecting groove 6, adjusting the distance between the equalizing frame 5 and the equalizing frame 4. After performing the translational connection, the handheld fixing frame 10 is moved up and down to contact the top of the screen box 2, and the fixing plate 11 is positioned on the right side of the screen box 2. At this time, the lifting seat 17 moves with the fixing frame 10 inside the lifting groove 16, performing the lifting connection between the fixing frame 10 and the fixing rod 9. Then, the handheld stud 13 is rotated to engage the screw hole 12, applying a threaded thrust to the left side of the fixing plate 11. At this time, the rotating seat 15 rotates with the stud 13 inside the rotating groove 14, performing the rotation connection between the stud 13 and the fixing plate 11. The dynamic connection operation causes the stud 13 to push the fixing plate 11 into contact and abut against the screen box 2, prompting the fixing plate 11 to cooperate with the fixing frame 10 and fixing rod 9 to fix the distribution frame 4 and distribution frame 5 to the screen box 2. Then, according to the application requirements of the polymer material to be screened on the screen 3, the distribution state of the distribution frame 4 and distribution frame 5 is adjusted. If it is necessary to keep the distribution frame 4 and distribution frame 5 stable at the top of the screen 3, there is no need to pull the positioning column 19. If it is necessary to move the distribution frame 4 and distribution frame 5 at the top of the screen 3, The positioning column 19 is moved inward to disengage from the positioning groove 20. At this time, the magnetic suction plate 22 moves with the positioning column 19 and performs magnetic positioning between the moved positioning column 19 and the positioning cylinder 18 through the magnetic plate 21. Then, the external polymer material is poured onto the top of the screen 3. At this time, the equalizing frame 4 cooperates with the equalizing frame 5 to perform low-level barrier equalization of the polymer material on the top of the screen 3, increasing the contact of the polymer material with vibration screening on the top of the screen 3, and prompting the screen 3 to perform equalization screening of the external polymer material.

[0036] It should be noted that the support 1, the screen box 2 and the screen 3 are all existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
