Description

Technical Field

[0001] This utility model relates to the field of dust prevention technology for tobacco storage cabinets, and in particular to a non-powered dust prevention soft curtain device for tobacco storage cabinets. Background Technology

[0002] In tobacco processing, materials are typically stored temporarily in storage cabinets. However, existing material storage cabinets lack effective protective devices above them. When the material placing machine feeds materials into the cabinet, the considerable height of the machine generates significant dust during the feeding process. This dust not only accumulates on the moving parts of the equipment, increasing wear and posing a fire hazard, but also causes material loss and adversely affects the working environment of the operators.

[0003] The existing technology mainly uses the following methods for processing:

[0004] One method is to use pleated blinds for dragging and covering. This method can reduce dust to some extent, but it has the problems of high cost, complex installation, and short maintenance cycle. It usually requires maintenance every six months and has a service life of about one year. Once damaged, it often needs to be replaced entirely, resulting in high repair costs.

[0005] Secondly, temporary coverings are used. Since the fabric cart above the storage cabinet is a moving part, the size of the cabinet cover will change with the movement of the fabric cart. Temporary coverings lack effective follow-up control and are prone to disorderly accumulation and knotting, which often requires manual intervention and is inconvenient to use.

[0006] It is evident that existing material storage tanks still suffer from drawbacks in terms of dust prevention, such as high cost, poor reliability, and inconvenient operation. There is an urgent need for an improved solution that is simple in structure, requires no power drive, adapts to the movement of fabric carriers, and can effectively prevent dust. Summary of the Invention

[0007] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a non-powered dustproof soft curtain device for tobacco storage cabinets to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A non-powered dustproof soft curtain device for tobacco storage cabinet includes: two sets of dustproof soft curtains; the two sets of dustproof soft curtains have the same structure, each including: two guide rail type hangings symmetrically arranged on the inner side of the outer frame of the tobacco storage cabinet, a soft curtain fixing frame detachably connected to the two guide rail type hangings, and a fold-resistant curtain fabric detachably connected to the soft curtain fixing frame; the soft curtain fixing frame is located below the two guide rail type hangings.

[0010] One end of the fold-resistant curtain in a set of dustproof soft curtains is fixedly connected to the rear end of the front dust collection cover, and the other end is fixedly connected to the front end of the moving trolley.

[0011] One end of the fold-resistant curtain in another set of dustproof soft curtains is fixedly connected to the rear end of the moving trolley, and the other end is fixedly connected to the front end of the rear dust collection cover.

[0012] Preferably, the guide rail type hanging includes: two guide rails symmetrically arranged on the inner side of the outer frame of the tobacco storage cabinet, a plurality of telescopic curtain rollers respectively installed in the two guide rails, and a plurality of roller connecting rods installed below each telescopic curtain roller; the number of telescopic curtain rollers installed in the two guide rails is the same; the telescopic curtain rollers can drive the roller connecting rods to slide on the guide rails; among the plurality of telescopic curtain rollers in the two guide rails, those that are equidistant from the end faces of the two guide rails form a group.

[0013] Preferably, the telescopic curtain hanging wheel includes: a connecting plate and four wheel bodies disposed on both sides of the connecting plate; the four wheel bodies are rotatably connected to the connecting plate, the connecting plate has a connecting hole, the top of the hanging wheel connecting rod has a threaded hole, and the connecting plate and the hanging wheel connecting rod are connected by bolts.

[0014] Preferably, the soft curtain fixing frame includes: a telescopic curtain horizontal rod whose two ends are respectively connected to the hanging wheel connecting rods below a set of telescopic curtain hanging wheels, and two telescopic curtain vertical rods detachably connected to the bottom of the telescopic curtain horizontal rod; both ends of the telescopic curtain horizontal rod are provided with threaded holes, the hanging wheel connecting rods are provided with connecting holes, and the telescopic curtain horizontal rods are detachably connected to the hanging wheel connecting rods by bolts; the distance between the two telescopic curtain vertical rods is greater than the width of the feed inlet opening above the tobacco storage cabinet.

[0015] Preferably, the telescopic curtain horizontal rod and the telescopic curtain vertical rod are connected by a T-joint, and the telescopic curtain horizontal rod is fitted with a clamp placed on the outside of the T-joint.

[0016] Preferably, the fold-resistant fabric forms a rectangular enclosure with an open bottom. The top surface of the rectangular enclosure of the fold-resistant fabric has several equidistant horizontal bar perforations, and the corresponding two side surfaces have several equidistant vertical bar perforations.

[0017] Preferably, the spacing between the holes in the crossbar is 300mm.

This invention utilizes the movement of a trolley to directly drive the expansion and contraction of the curtain fabric, eliminating the need for an additional power device. During the fabric feeding process, the fold-resistant curtain fabric can cover the feed inlet, effectively blocking dust generated during material feeding, reducing material loss, and improving the working environment. The fold-resistant curtain fabric, combined with the guide rail structure, moves smoothly, avoiding damage caused by repeated stacking and knotting, and extending its service life.
