Dust and static electricity removing equipment for PVC film delivery

Abstract

This application belongs to the technical field of dust removal and static electricity removal equipment, and particularly relates to a dust removal and static electricity removal device for PVC film leaving the factory. The device includes a dust removal chamber, with an inlet trough and an outlet trough fixedly installed on its left and right sides respectively. Guide components are provided in both the inlet and outlet troughs. Two symmetrically arranged driven shafts are rotatably mounted inside the dust removal chamber, and static electricity removal rollers are fixedly mounted on the driven shafts. A movable ball is movably disposed inside the dust removal chamber, positioned between the two static electricity removal rollers. In this invention, the drive motor rotates the drive shaft, causing the incomplete gear to drive the rectangular gear frame to move up and down reciprocally. The movable ball moves up and down, agitating the PVC film and thus ejecting dust, improving the dust removal effect. Furthermore, the transmission disc on the drive shaft drives the transmission belt to rotate, enabling the driven shaft to drive the static electricity removal rollers to rotate, allowing the PVC film to be smoothly conveyed and subjected to static electricity removal treatment.

Description

Technical Field

[0001] This utility model relates to a dust removal and static electricity removal device, specifically a dust removal and static electricity removal device for PVC film leaving the factory. Background Technology

[0002] PVC film is mainly composed of polyurethane, with other components added to enhance its heat resistance, toughness, and ductility. The top layer of this surface film is paint, the middle layer is mainly polyurethane, and the bottom layer is a backing adhesive. It is a popular and widely used synthetic material in the world today.

[0003] Currently, film forming equipment is frequently used during film processing and shipment. However, existing film forming equipment lacks dust removal capabilities. After film forming, the film needs to be wound up. Since the air around the film forming equipment contains a significant amount of dust, dust often adheres to the surface of the film. If left untreated for a long time, this dust accumulates on each layer of film, affecting the quality of the finished film. Furthermore, static electricity is generated during the film forming process through friction with rubber rollers, requiring static elimination during winding. Therefore, a dust removal and static elimination device for PVC film shipment is needed. Utility Model Content

[0004] The main objective of this disclosure is to provide a dust removal and static electricity removal device for PVC film at the factory, so as to effectively solve the problems raised by the inventors in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dust removal and static electricity removal device for PVC film leaving the factory includes a dust removal chamber. An inlet trough and an outlet trough are fixedly installed on the left and right sides of the dust removal chamber, respectively. A guide component is provided in both the inlet trough and the outlet trough. Two symmetrically arranged driven shafts are rotatably installed inside the dust removal chamber, and static electricity removal rollers are fixedly installed on the driven shafts. A toggle ball is movably installed inside the dust removal chamber and is located between the two static electricity removal rollers.

[0007] Preferably, two Z-axis rods are fixedly installed on the inner bottom wall of the dust removal chamber, and sliders are slidably installed on the Z-axis rods. A rectangular toothed frame is fixedly installed between the two sliders, and the actuating ball is fixedly connected to the top of the rectangular toothed frame.

[0008] Preferably, a drive motor is fixedly installed on the rear inner wall of the dust removal chamber, and the output end of the drive motor is fixedly connected to a drive shaft. A broken gear is fixedly installed on the drive shaft, and teeth are fixedly installed on both sides of the rectangular gear frame. The broken gear meshes with the teeth on one side of the rectangular gear frame for transmission.

[0009] Preferably, both the driven shaft and the driving shaft are fixedly mounted with a transmission disc at one end outside the dust collector, and the three transmission discs are connected by a transmission belt.

[0010] Preferably, the guiding assembly includes a feed shaft and a guide roller. Two feed shafts, arranged vertically, are rotatably installed in both the inlet and outlet grooves, and guide rollers are fixedly installed on the feed shafts.

[0011] Preferably, a bag filter is fixedly installed on the top of the dust removal chamber, and the suction end of the bag filter extends into the dust removal chamber and is fixedly connected to a flared opening.

[0012] Preferably, a threaded sleeve is fixedly connected to the bottom of the dust removal chamber, and a collection hopper is threadedly connected to the bottom end of the threaded sleeve.

[0013] In view of this, compared with the prior art, the beneficial effects of this utility model are:

[0014] (i) In this application, the PVC film processed and shipped out is sent from the inlet tank to the dust removal chamber, passes around two antistatic rollers and is then sent out from the outlet tank. The guide roller guides and conveys the PVC film. During the conveying process, the antistatic roller removes static electricity from the PVC film, so that the antistatic PVC film can be rolled and packaged at the factory. During the conveying, the bag vacuum cleaner works to remove dust from the PVC film in the dust removal chamber, thereby improving the quality of the PVC film leaving the factory.

[0015] (ii) In this application, the drive motor works and drives the drive shaft to rotate. That is, the incomplete gear drives the rectangular tooth frame to move up and down reciprocally, and the agitator ball will move up and down, causing it to agitate the PVC film and thus pop out the dust on it, improving the dust removal effect. The transmission disc on the drive shaft will drive the transmission belt to rotate, so that the driven shaft can drive the antistatic roller to rotate, so that the PVC film can be smoothly transported and subjected to antistatic treatment.
