Description

Technical Field

[0001] The invention relates to the technical field of resin processing, and in particular to a furan resin particle screening device. Background Art

[0002] Resin particles are chemical raw materials with excellent performance and wide applications. In the production process of resin particles, a vibrating screening machine is needed to screen them for later processing. Most of the existing screening machines drive the threaded rod to rotate by turning the handle, and then the push plate pushes the residual material on the screen plate, thereby effectively improving the convenience of cleaning the residual material. However, the staff needs to manually rotate the threaded rod to achieve this, which makes it inconvenient to automatically clean the residual material on the screen plate, resulting in low practicality. In addition, when the screen plate is filtering the residual material, some residual material is easily blocked in the holes on the screen plate, which is inconvenient to be cleaned up, affecting the subsequent screening work, and then resulting in reduced work efficiency.

[0003] Therefore, we proposed a furan resin particle screening device that can well solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a furan resin particle screening device to solve the above-mentioned technical problems in view of the shortcomings of the prior art.

[0005] The embodiment of the present invention adopts the following technical scheme: a furan resin particle screening device includes a device box, a feeding hopper is arranged on the top of the device box, a filter screen is installed inside the device box, discharge ports are symmetrically opened on both sides of the filter screen, and receiving boxes corresponding to the discharge ports are detachably provided on both sides of the filter screen, a cleaning mechanism is movably arranged on the top of the filter screen, a cavity is formed inside the rear side of the device box, a moving mechanism is accommodated inside the cavity, a linkage mechanism is arranged at the coupling point between the moving mechanism and the cleaning mechanism, and a driving mechanism is arranged at the driving end of the moving mechanism.

[0006] Preferably, a storage groove is provided on an inner wall of one side of the device box.

[0007] Preferably, the driving mechanism comprises a protective cover installed on the outer surface of one side of the device housing, and a motor is arranged inside the protective cover.

[0014] Compared with the related art, the furan resin particle screening device provided by the present invention has the following beneficial effects: The present invention provides a furan resin particle screening device. When cleaning impurities on a filter screen, the motor is started so that the rotating shaft can rotate in both positive and negative directions, so that the screw can drive the ball nut to move back and forth horizontally on its outer wall, thereby ensuring that the fixed plate will drive the cleaning brush to move back and forth horizontally on the surface of the filter screen. Since the cleaning brush is a nylon brush with relatively hard and wear-resistant bristles, the cleaning brush can conveniently and quickly clean large particles and debris, thereby not only ensuring the normal filtering of the filter screen, but also, during the raw material filtering process, the motor drives the cleaning brush to move back and forth, which can achieve the effect of flattening the raw materials, thereby improving the filtering efficiency.

[0020] In the specific implementation process, Figure 1 and Figure 2 As shown, the driving mechanism 3 includes a protective cover 31 installed on the outer surface of one side of the device box 1, and a motor 32 is arranged inside the protective cover 31.

[0021] When in use, the motor 32 is installed inside the protective cover 31, which can prevent collision and protect the motor 32, thereby extending the service life of the motor 32, and the heat dissipation ports opened at the front and rear of the protective cover 31 can dissipate heat for the motor 32.

[0022] refer to Figure 2As shown, a rotating shaft 33 is fixed to the driving end of the motor 32 , and one end of the rotating shaft 33 away from the motor 32 rotates and extends to the inside of the cavity 10 .

[0023] When in use, when the motor 32 is running, the rotating shaft 33 will rotate in both clockwise and counterclockwise directions to prepare for driving the moving mechanism 6 to rotate later.

[0024] refer to Figure 1 and Figure 2 As shown, the moving mechanism 6 includes a screw rod 61 fixed to the outer wall of the end of the rotating shaft 33 , and one end surface of the screw rod 61 away from the rotating shaft 33 is connected to a bearing of an inner wall of one side of the cavity 10 .

[0025] When in use, the screw rod 61 is connected to the rotating shaft 33 . When the rotating shaft 33 rotates, the screw rod 61 will also rotate synchronously therewith, so as to prepare for driving the ball nut 62 to move later.

[0026] refer to Figure 2 As shown, the linkage mechanism 11 includes a slide groove 111 opened on the inner wall of the rear side of the device box, and a slide rod 112 is movably arranged inside the slide groove 111. One end of the slide rod 112 is fixedly connected to the ball nut 62.

[0027] When in use, the ball nut 62 is threadedly sleeved on the outer wall of the screw 61. When the screw 61 rotates, the ball nut 62 will move back and forth horizontally on the outer wall of the screw 61 to prepare for driving the cleaning brush 92 to move later.

[0028] refer to Figure 2 As shown, the linkage mechanism 11 includes a slide groove 111 opened on the inner wall of the rear side of the device box 1, and the slide groove 111 is communicated with the cavity 10.

[0029] When in use, the slide groove 111 is provided to prepare for the sliding rod 112 to drive the fixing plate 91 to move back and forth on the top of the filter screen 4.

[0030] refer to Figure 2 As shown, a slide rod 112 is movably provided inside the slide groove 111 , and one end surface of the slide rod 112 inside the cavity 10 is fixed to the front surface of the ball nut 62 .

[0031] When in use, the slide rod 112 is connected to the ball nut 62 , and when the ball nut 62 moves on the outer wall of the screw rod 61 , the slide rod 112 will move synchronously therewith.

[0032] refer to Figure 2As shown, the cleaning mechanism 9 includes a fixing plate 91 fixed to one end surface of the slide rod 112 inside the device housing 1, a cleaning brush 92 is fixed to the bottom surface of the fixing plate 91, and the bottom surface of the cleaning brush 92 is in close contact with the top surface of the filter screen 4.

[0033] When in use, the fixing plate 91 is installed at the bottom of the ball nut 62. When the ball nut 62 moves on the outer wall of the screw 61, the slide rod 112 will drive the cleaning brush 92 to move synchronously on the top of the filter screen 4, so that the cleaning brush 92 can conveniently and quickly clean the debris and large particles that are accumulated or blocked on the surface of the filter screen 4.

[0034] refer to Figure 2 As shown, a storage groove 5 is provided on an inner wall of one side of the device housing 1 .

[0035] When in use, a storage groove 5 is opened on the inner wall of one side of the device box 1, so that the cleaning mechanism 9 can be stored inside the storage groove 5 when it is not needed, avoiding debris and large particles in the resin from falling onto the cleaning mechanism 9 and affecting the service life of the cleaning mechanism 9.

[0036] Working principle: When the resin particles enter the device box 1 through the hopper 2, the filter 4 will filter the debris and large particles of the resin entering the device box 1. When the required raw materials have completed the filtering work, the surface of the filter 4 will have the filtered debris and large particles. In order not to affect the filtering effect of the filter 4 on the resin, the surface of the filter 4 needs to be cleaned. First, the motor 32 is started to allow the rotating shaft 33 to rotate in both directions, so that the screw 61 will rotate synchronously in the same direction as the rotating shaft 33 rotates, so that the ball nut 62 threadedly sleeved on the outer wall of the screw 61 will rotate with the screw 61. The ball nut 62 is rotated to move back and forth horizontally on the outer wall of the ball nut 62, so that the fixed plate 91 will move with the movement of the slide rod 112, driving the cleaning brush 92 to move back and forth horizontally on the surface of the filter screen 4. Since the cleaning brush 92 is a nylon brush, the bristles are relatively hard and wear-resistant, and can easily and quickly clean up the debris and large particles accumulated or blocked on the surface of the filter screen 4. Then, the cleaned debris and large particles are introduced into the interior of the receiving box 8 through the two groups of discharge ports 7 opened on the top of the filter screen 4, and the debris and large particles are temporarily stored to avoid being directly discharged into the interior of the device box 1, which affects the later filtering work of the resin.

For those skilled in the art, the present invention may have various modifications and variations.
