Description

Technical Field

[0001] This utility model belongs to the technical field of fiber powder screening, specifically relating to a fiber powder screening device with multiple screening functions. Background Technology

[0002] The working principle of the fiber powder screening device is to use the high-frequency vibration force generated by the vibrating motor to screen and separate the fiber powder on the screen. The size of the screen aperture can be adjusted as needed to screen fiber powder of different particle sizes. However, the discharge port height of the multi-layer fiber powder screening device is different. In addition, the fiber powder is relatively light, which causes the fiber powder to be blown away by the airflow in the production workshop when it falls from the discharge port. It cannot fall accurately into the collection bucket, resulting in the fiber powder being scattered and wasted during collection. Utility Model Content

[0003] The purpose of this invention is to provide a fiber powder screening device with multiple screening functions, in order to solve the problem in the above-mentioned multi-layer fiber powder screening device where the discharge port height is different and the fiber powder is relatively light. As a result, the fiber powder is blown away by the airflow in the production workshop when it falls from the discharge port, and cannot fall accurately into the collection bucket, thus causing the fiber powder to be scattered and wasted during collection.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fiber powder screening device with multiple screening functions, comprising a sieve cylinder and a discharge port;

[0005] Both of the screen cylinders are provided with a discharge port at their outer ends;

[0006] A telescopic tube is sleeved on the outer wall of the discharge port;

[0007] A fixing strap is wound around the upper outer wall of the telescopic tube. A fixing block is provided at the first section of the fixing strap. An insertion hole is opened at the front end of the fixing block. The fixing strap is wound around the outer wall of the telescopic tube and inserted into the insertion hole of the fixing block and fixed by screws.

[0008] Preferably, the telescopic tube is made of food-grade PVC material, and the inner wall of the telescopic tube has been polished.

[0009] Preferably, the fixing strap and the fixing block are made of a single piece of stainless steel.

[0010] Preferably, a screen box is provided at the lower end of the screen cylinder, a base is provided on the lower side of the screen box, and a power cord is provided at the left end of the base.

[0011] Preferably, a vibrator is provided between the inner wall of the base and the screen box, and the vibrator is used to drive the screen cylinder at the upper end of the screen box to vibrate.

[0012] Preferably, a plurality of vibration springs are provided between the screen box and the base, and the plurality of vibration springs are used to support the screen box.

[0013] Preferably, the upper end of the screen cylinder is provided with a dust cover, which is used to prevent dust from entering the screen cylinder, and the upper end of the dust cover is provided with a feed inlet.

[0014] Compared with the prior art, the present invention provides a fiber powder screening device with multiple screening functions, which has the following beneficial effects:

[0015] The telescopic tube is fitted onto the lower outer wall of the discharge port. The fixing strap is wrapped around the upper outer wall of the telescopic tube, and the end of the fixing strap is pulled out from the insertion hole of the fixing block. The screw is then screwed into the fixing block to fix the fixing strap in the insertion hole. Thus, the telescopic tube is firmly fixed to the outer wall of the discharge port by the fixing strap. The vibrator drives the screen cylinder at the top of the screen box to vibrate, thereby screening the fiber powder in the screen cylinder. When collecting the fiber powder discharged from the discharge port, the telescopic tube can be pulled down to extend it, so that the telescopic tube can be inserted into the container for collecting fiber powder. When the fiber powder falls downward, it can be guided by the telescopic tube to prevent it from drifting outward, avoiding the problem of fiber powder scattering everywhere and causing waste due to excessive drop between the discharge port and the collection container.
