Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco shredders, and in particular to a tobacco shredder with an automatically lifting push plate. Background Art
[0002] As one of the key process equipment in the production of tobacco threads in cigarette factories, the main function of the shredder is to cut tobacco leaves or stems processed in the previous process into shredded leaves or stems with a certain width according to the requirements of the shredding process. After each production, it is necessary to open the push plate on the shredder to push out the tailings and clean the gaps and grooves of the copper bar chain inside the shredder to remove the tobacco foam and dirt inside.
[0003] Most of the existing push plates of the wire cutters are manually lifted, and then the tail of the push plate is hung with a hook to fix it. This process consumes a lot of physical strength of the workers. After the push plate is lowered from the wire cutter and fixed, the lowest vertical height of the push plate is only 1.6 meters from the bottom surface. When the workers push the tail of the wire cutter and dismantle the chain for cleaning, the push plate on the hook is prone to swing slightly, causing the workers to collide with the push plate, posing a safety hazard. Utility Model Content
[0004] The utility model is to solve the problem that the workers consume a lot of physical strength in the process of fixing the push plate in the above-mentioned prior art solutions, and the push plate is prone to swing slightly after being fixed, and provide a tobacco shredder with automatic lifting of the push plate. In this solution, an electric hoist is used to drive the push plate to lift, avoiding the troublesome and laborious manual lifting of the push plate, and the push plate is not easy to swing after being fixed, avoiding workers from bumping into it.
[0005] The technical solution adopted by the utility model is: a tobacco shredder with an automatically lifting push plate, comprising a shredder, a push plate and an electric hoist, the push plate being movably connected to the shredder, the electric hoist being located above the shredder in the vertical direction to drive the push plate to move on the shredder, so that a push port of the shredder is opened or closed, a hanging ring fixedly connected to the push plate is provided on the push plate, and the hanging ring is connected to a hook at the end of a telescopic chain of the electric hoist.
[0006] In this solution, an electric hoist is used as a driving device to drive the push plate on the wire cutter to move, so that the push port of the wire cutter is opened or closed. The electric hoist replaces manual drive to avoid manually driving the push plate to increase the labor intensity of workers. The electric hoist has the advantages of light weight, small size, compact structure, smooth operation and simple operation. When the electric hoist drives the push plate to reach the movement limit and stop moving, the telescopic chain on the electric hoist will not swing, avoiding the push plate swinging and causing workers to bump.
[0007] Preferably, the electric hoist and the push port of the wire cutter are located on the same vertical plane, the push plate can slide on the wire cutter, an L-shaped limit block is fixedly connected to the side wall of the push port of the wire cutter, a U-shaped limit groove is formed between the limit block and the wire cutter, and the push plate can extend into the limit groove and be slidably connected with the limit groove. The limit blocks on the two side walls of the push port of the wire cutter are symmetrically arranged with the central axis in the vertical direction of the push port, and each side wall of the push port of the wire cutter is provided with a plurality of limit blocks, and the plurality of limit blocks are linearly arranged on the side wall of the push port of the wire cutter. The push plate moves on the wire cutter in an up-and-down sliding manner. After the push plate slides upward to the push port of the punched wire cutter, the staff can push the tail material out through the push port and clean the gap and groove at the connection of the copper bar chain of the wire cutter, and remove the smoke and dirt inside. The push plate moves upward to open the push port, which can prevent the opened push plate from affecting the normal work of the staff. The limiting groove formed by the limiting block and the wire cutter can limit the sliding direction of the push plate to prevent the push plate from deflecting during the sliding process. There are several limiting blocks, which have a better limiting effect on the push plate.
[0008] Preferably, it also includes a first in-place detection unit for detecting whether the push plate has risen to the maximum height, the first in-place detection unit is a slot-type photoelectric switch, the first in-place detection unit is located on the wire cutter and is fixedly connected to the wire cutter. It also includes a first alarm device, the first alarm device includes a warning light and a buzzer, the first alarm device is fixedly connected to the wire cutter, and the first in-place detection unit is electrically connected to the first alarm device.

The push plate is rotatably connected to the wire cutter, and under the action of the push plate's own gravity, the push plate will rotate downward. When the electric hoist contracts the telescopic chain, it can drive the push plate to rotate upward and close the push port of the wire cutter. The angle between the push plate and the wire cutter is adjusted by the length of the telescopic chain of the electric hoist to control the opening and closing of the push port of the wire cutter. This method allows the push plate to play a guiding and supporting role for the tailings in the wire cutter, making it easier to collect the tailings. The hanging ring is located at the center of the top of the push plate, so that when the electric hoist controls the push plate to rotate on the wire cutter, the force on the top of the push plate is more uniform.
[0010] Preferably, it also includes a slide rail, which is located above the wire cutter in the vertical direction, and the axis of the slide rail is perpendicular to the plane where the wire cutter push port is located. The electric hoist is located on the slide rail and is slidably connected to the slide rail.

After the slide rail and the driving unit are set, when the telescopic chain on the electric hoist needs to be extended or contracted, so that the push plate rotates on the wire cutter, the driving unit will drive the electric hoist to slide on the slide rail, so that the electric hoist moves with the rotation of the push plate, and the telescopic chain on the electric hoist does less useless work when providing tension for the push plate, and it is more convenient for the electric hoist to drive the telescopic chain to move. In addition to the telescopic cylinder, the driving unit can also be a telescopic oil cylinder or a telescopic hydraulic cylinder.
[0011] Preferably, it also includes a chain longest in-place detection part and a chain shortest in-place detection part, both of which are slot-type photoelectric switches, and both of which are fixedly connected to the wire cutter. The longest in-place detector and the shortest in-place detector can be used to determine whether the extension length of the telescopic chain of the electric hoist has reached the longest limit or the shortest limit, and then determine the state of the push plate on the wire cutter. When the extension length of the telescopic chain is the longest, the push plate opens the push port; when the extension length of the telescopic chain is the shortest, the push plate closes the push port.
[0012] Preferably, a second alarm device is also included, the second alarm device includes a warning light and a buzzer, the second alarm device is fixedly connected to the wire cutter, and the longest chain detection part and the shortest chain detection part are both electrically connected to the second alarm device.
