Description

Technical Field

[0001] This utility model relates to the field of tension sieve technology, specifically a combined tension sieve. Background Technology

[0002] A tension screen is a screening machine that uses the tensioning and relaxing motion of an elastic screen surface mounted on an inclined screen box to throw materials. Its working principle is based on the motion characteristics of materials on a vibrating screen. The vibration of the screen causes relative motion of the materials on the screen surface, thereby achieving material separation and screening.

[0003] In existing tension screens, materials are directly poured onto the screen plate and then rolled along the inclined surface of the plate under vibration to achieve screening. However, material tends to accumulate on the surface of the screen plate, hindering uniform material distribution and affecting screening efficiency and effectiveness. Therefore, we propose a combined tension screen. Utility Model Content

[0004] The purpose of this invention is to provide a combined tension screen that solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a combined tension sieve, comprising a frame, wherein sieve plates are fixed at both the top and bottom of the inner cavity of the frame, the holes of the lower sieve plate are smaller than the holes of the upper sieve plate, and a vibration motor is fixed at the bottom of the frame;

[0006] An adjusting plate is fixed to the bottom of one end of the frame. A sliding groove is provided at the bottom of the adjusting plate. A lead screw motor is fixed to one end face of the inner cavity of the sliding groove. A lead screw is fixedly connected to the outer end of the drive shaft of the lead screw motor. The outer end of the lead screw is rotatably connected to the inner wall of the sliding groove. A matching lead screw slider is fitted on the outer wall of the lead screw. A carrier is fixedly connected to the bottom of the lead screw slider. Movable rods are connected to the upper and lower sides of one side wall of the carrier. The two movable rods are located on the upper side of the two screen plates respectively.

[0007] By adopting the above technical solution, the material is first introduced into the screen plate, and then the vibration motor is started to drive the frame to vibrate, thereby realizing the screening of the material. During the screening process, the screw motor is started to drive the screw to rotate, thereby driving the screw slider to move back and forth, which in turn moves the frame, so that the movable rod can spread the material on the screen plate evenly, which is conducive to the uniform distribution of the material on the screen plate and improves the screening effect and screening efficiency.

[0008] In a preferred embodiment of this utility model, a plurality of evenly distributed material feeding components are connected to one side wall of the movable rod, and a servo motor is fixed on the outer wall of the carrier corresponding to the movable rod. The drive shaft of the servo motor passes through the carrier and is fixedly connected to the end of the movable rod.

[0009] By adopting the above technical solution, when the movable rod moves to spread the material evenly, the servo motor is started to drive the movable rod to rotate, which in turn drives the material feeding component to rotate downwards. This allows the material feeding component to feed the material, thereby improving the material spreading effect and further enhancing the screening effect.

[0010] In a preferred embodiment of the present invention, the feeding assembly includes a sleeve, the inner cavity of the sleeve is provided with a suitable sliding plate, a connecting post is fixed to one side wall of the sliding plate, the connecting post passes through the sleeve and is fixedly connected to the movable rod, and a second spring is fixed to the other side wall of the sliding plate, the outer end of the second spring is fixedly connected to the inner wall of the sleeve.

[0011] By adopting the above technical solution, the servo motor can drive the movable rod to rotate, thereby causing the material feeding component to rotate and impact the screen plate. At this time, the sleeve will compress the second spring. Under the condition of the device itself vibrating, the second spring can increase the amplitude, which is conducive to improving the vibration screening effect of the screen plate. At the same time, the material feeding component can further improve the uniformity of the material by moving the material.

[0012] In a preferred embodiment of this utility model, guide plates are fixedly connected to the tail ends of both screen plates, and the two guide plates are arranged alternately.

[0013] By adopting the above technical solution, the guide plate is designed to allow the screened material to be discharged.

[0014] In a preferred embodiment of this utility model, a fixing block is fixed to both sides of the two side walls of the frame, a first spring is fixed to the bottom of the fixing block, a support column is fixed to the bottom of the first spring, a base is fixed to the tail end of the support column, and mounting holes are provided at the four corners of the top of the base.

[0015] By adopting the above technical solution, the base makes it easy to install and fix the whole device, while the first spring increases the amplitude during vibration, which helps to ensure the screening effect.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The present application provides a combined tension screen, in which the adjusting plate drives the carrier to move back and forth, thereby driving the movable rod to move back and forth, thus spreading the material on the screen plate surface evenly, which helps to avoid local accumulation of material, thus facilitating uniform material distribution and screening, and improving the efficiency and effect of material screening.

[0018] The servo motor drives the movable rod to rotate, which causes the actuating component to rotate and impact the screen plate. At this time, the sleeve will compress the second spring. Under the condition of the device's own vibration, the second spring can increase the amplitude, which is conducive to improving the screen plate's vibration screening effect. At the same time, using the actuating component to move the material can further improve the material uniformity. Attached Figure Description

[0027] Please see Figure 1-3 This utility model provides a technical solution: a combined tension sieve, including a frame 1, with sieve plates 11 fixed at both the top and bottom of the inner cavity of the frame 1, the holes of the lower sieve plate 11 being smaller than the holes of the upper sieve plate 11, and a vibration motor fixed at the bottom of the frame 1.

[0028] An adjusting plate 2 is fixed to the bottom of one end of the frame 1. A sliding groove is provided at the bottom of the adjusting plate 2. A lead screw motor 24 is fixed to one end of the inner cavity of the sliding groove. A lead screw 25 is fixedly connected to the outer end of the drive shaft of the lead screw motor 24. The outer end of the lead screw 25 is rotatably connected to the inner wall of the sliding groove. A suitable lead screw slider 26 is fitted on the outer wall of the lead screw 25. A carrier frame 21 is fixedly connected to the bottom of the lead screw slider 26. Movable rods 23 are connected to the upper and lower sides of one side wall of the carrier frame 21. The two movable rods 23 are located on the upper side of the two screen plates 11 respectively.

[0029] In actual use, the material is first introduced onto the screen plate 11, and then the vibration motor is started to drive the frame 1 to vibrate, thereby achieving the screening of the material. During the screening process, the screw motor 24 is started to drive the screw 25 to rotate, thereby driving the screw slider 26 to move back and forth, which in turn moves the carrier 21, so that the movable rod 23 can spread the material on the screen plate 11 evenly, which is conducive to the uniform distribution of the material on the screen plate 11 and improves the screening effect and screening efficiency.

[0030] Furthermore, fixing blocks 12 are fixed on both sides of the frame 1, and a first spring 13 is fixed to the bottom of the fixing block 12. A support column 14 is fixed to the bottom of the first spring 13, and a base 15 is fixed to the tail end of the support column 14. Mounting holes are provided at the four corners of the top of the base 15. The base 15 facilitates the installation and fixing of the entire device. At the same time, the first spring 13 increases the amplitude during vibration, which helps to ensure the screening effect.

[0031] Furthermore, guide plates 16 are fixedly connected to the tail ends of both screen plates 11. The two guide plates 16 are staggered, and the arrangement of the guide plates 16 enables the screened material to be discharged.

[0032] like Figure 1 and 3 As shown; a plurality of evenly distributed material feeding components 3 are connected to one side wall of the movable rod 23, and a servo motor 22 is fixed on the outer wall of the carrier 21 corresponding to the movable rod 23. The drive shaft of the servo motor 22 passes through the carrier 21 and is fixedly connected to the end of the movable rod 23.

[0033] In actual use, when the movable rod 23 moves to spread the material evenly, the servo motor 22 is started to drive the movable rod 23 to rotate, which in turn drives the material feeding component 3 to rotate downwards. This allows the material feeding component 3 to feed the material, thereby improving the material spreading effect and further enhancing the screening effect.

[0034] Furthermore, the feeding assembly 3 includes a sleeve 31, the inner cavity of the sleeve 31 is provided with a matching sliding plate 32, a connecting post 33 is fixed on one side wall of the sliding plate 32, the connecting post 33 passes through the sleeve 31 and is fixedly connected to the movable rod 23, and a second spring 34 is fixed on the other side wall of the sliding plate 32, the outer end of the second spring 34 is fixedly connected to the inner wall of the sleeve 31.

[0035] The servo motor 22 drives the movable rod 23 to rotate, which causes the material feeding assembly 3 to rotate and impact the screen plate 11. At this time, the sleeve 31 will compress the second spring 34. Under the condition of the device itself vibrating, the second spring 34 can increase the amplitude, which is conducive to improving the vibration screening effect of the screen plate 11. At the same time, the material feeding assembly 3 can further improve the uniformity of the material by moving the material.

[0036] The implementation principle of the combined tension screen of this application is as follows: In actual use, the material is first introduced onto the screen plate 11, and then the vibration motor is started to drive the frame 1 to vibrate, thereby achieving material screening. During the screening process, the screw motor 24 is started to drive the screw 25 to rotate, thereby driving the screw slider 26 to move back and forth, which in turn moves the carrier 21, so that the movable rod 23 can spread the material on the screen plate 11 evenly, which is beneficial to the uniform distribution of the material on the screen plate 11 and to improving the screening effect and screening efficiency. At the same time, when the movable rod 23 moves to spread the material evenly, the screen is activated. The servo motor 22 drives the movable rod 23 to rotate, which in turn drives the material feeding component 3 to rotate downwards. This allows the material feeding component 3 to feed the material, thereby improving the material spreading effect and further enhancing the screening effect. The servo motor 22 drives the movable rod 23 to rotate, causing the material feeding component 3 to rotate and impact the screen plate 11. At this time, the sleeve 31 will compress the second spring 34. Under the condition of the device's own vibration, the second spring 34 can increase the amplitude, which is conducive to improving the vibration screening effect of the screen plate 11. At the same time, the material feeding component 3 can further improve the material uniformity by feeding the material.
