Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to an automatic defoaming device for the cigarette machine's rewind groove. Background Technology

[0002] The ZJ17 cigarette rolling machine is a high-speed cigarette rolling device widely used in my country's tobacco industry. The ZJ17 cigarette rolling machine's return vibrating trough delivers tobacco to the tobacco storage area in the basket. During this process, dust from the tobacco falls onto the equipment or the ground through the gaps on both sides of the vibrating trough, affecting the workshop environment and posing a dust safety hazard.

[0003] To address the aforementioned technical issues, existing technology involves placing a dust collection tray below the gap in the equipment. Specifically, the dust collection tray is made of a flat sheet of iron with edging around its edges. The tray is supported on the base of the equipment. When the tray is full of tobacco dust, the operator removes it from the equipment, cleans the dust, and then places the tray back in its original position, repeating this process.

[0004] The existing technology has the following technical defects: Although the aforementioned dust collection tray can collect tobacco dust and achieve the effect of defoaming, it still has shortcomings. On the one hand, after the tobacco dust falls from the gaps in the vibrating groove and then falls onto the dust collection tray, there is a vertical gap, and some tobacco dust will drift outside the dust collection tray and fall to the ground, resulting in incomplete defoaming. On the other hand, the dust collection tray needs to be emptied and disposed of regularly by staff; otherwise, the dust will gradually accumulate and easily overflow onto the equipment, increasing the labor intensity of the staff and wasting time and effort. The workshop safety inspection and on-site management have repeatedly proposed thorough rectification of this problem. Utility Model Content

[0005] This application provides an automatic defoaming device for the cigarette machine's rewind trough, which solves the problem that existing defoaming devices do not completely remove dust, requiring staff to regularly empty and dispose of the dust in the dust collection tray, increasing the labor intensity of staff and wasting time and effort.

[0006] The technical solution adopted in this application is as follows:

[0007] An automatic defoaming device for the rewinding groove of a cigarette machine includes a dust collection hopper and a support rail. The support rail is installed on the outer shell of the cigarette machine, and the dust collection hopper is supported on the support rail. The top of the dust collection hopper contacts the bottom wall of the rewinding groove, and a dust removal pipe is provided at the bottom. One end of the dust removal pipe is connected to the inside of the dust collection hopper, and the other end is connected to an external dust removal system.

[0008] By setting up the above structure, the workshop's built-in dust removal system continuously sucks away the tobacco dust that falls into the dust collection hopper through the dust removal pipe, eliminating the need for staff to clean it regularly; and by using the support guide rail, the top of the dust collection hopper can be made to fit as close as possible to the bottom wall of the return trough, ensuring thorough defoaming.

[0009] Furthermore, the support rail is composed of two angle irons, the length direction of which is parallel to the length or width direction of the cigarette machine. The two angle irons are arranged in parallel and spaced apart. A locking device is provided between the vertical section of the angle iron and the outer shell of the cigarette machine. The two ends of the dust collection hopper are respectively movably supported on the horizontal sections of the two angle irons.

[0010] Furthermore, the locking component includes a screw and a first nut. The vertical section of the angle iron has an elongated through groove along the vertical direction. One end of the screw is fixedly connected to the outer casing of the cigarette machine, and the other end passes through the elongated through groove and engages with the first nut.

[0011] By setting up the above structure and turning the first nut, the vertical height of the support guide rail can be adjusted, thereby adjusting the vertical height of the dust collection hopper.

[0012] Furthermore, a dust collecting plate is installed on the top of the dust collecting hopper. The dust collecting plate is horizontally arranged and has a rectangular frame structure. Horizontal extension plates are provided at opposite ends of the top of the dust collecting hopper. Fixing members are provided between the horizontal extension plates and the dust collecting plate. The bottom of the dust collecting plate is supported on the horizontal section of the angle iron. A dust collecting frame is installed on the edge of the dust collecting plate.

[0013] Furthermore, a pull-out plate is provided on the top of one side wall of the dust collection frame. The pull-out plate is U-shaped and is installed on the dust collection frame with its opening facing downwards. One end of the wing plate of the pull-out plate is fixedly connected to the side wall of the dust collection frame. The opening of the pull-out plate is located outside the cigarette machine, and the outer side wall of the wing plate of the pull-out plate is in contact with the outer shell of the cigarette machine.

[0014] By setting up the above structure, the overall dust collection structure composed of the dust collection plate and the dust collection frame can completely cover the gap of the rewind groove, while perfectly fitting the narrow space at the bottom of the rewind groove of the cigarette machine. At the same time, the dust collection plate can slide well on the support rail, and the staff can easily pull the dust collection hopper out or put it in the cigarette machine by pulling out the plate.

[0015] Furthermore, a magnetic strip is embedded in the pull-out plate, and the pull-out plate is magnetically connected to the cigarette machine casing through the magnetic strip.

[0016] By setting up the above structure, the dust collection hopper can be stably placed below the wire return vibrating groove.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The automatic defoaming device for the cigarette machine's return trough of this application has a dust collection hopper that can collect tobacco dust falling from the gaps in the return trough. The funnel-shaped dust collection hopper has a larger capacity and can hold more tobacco dust. At the same time, the dust collection hopper is connected to the dust removal system of the workshop through a dust removal pipe. The dust removal system generates a continuous negative pressure that can suck away the tobacco dust collected in the dust collection hopper, realizing automatic dust extraction, preventing dust accumulation and overflow, eliminating the need for workers to empty it regularly, and reducing the labor intensity of workers.

[0019] 2. By setting a support guide rail, the dust collection hopper is supported on the support guide rail, so that the top of the dust collection hopper can be as close as possible to the bottom wall of the outer shell of the return vibration groove. The tobacco dust falls directly into the dust collection hopper from the gap of the return vibration groove. The structure is simple and the defoaming is thorough. Attached Figure Description
