Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of equipment disassembly, in particular to a device for clamping and pulling equipment in a small space. Background Art
[0002] The stem cutter is the main equipment on the stem production line in the tobacco making workshop of a cigarette factory. It is used to compact and cut the processed tobacco stems into stem cuts under the movement of upper and lower chains.
[0003] In the actual production process, since tobacco stems contain water, tobacco oil may be squeezed out and attached to the chain during the compaction process. After the equipment has been running for a long time, the tobacco oil will cause the chain to stick, which may cause problems such as uneven stem thickness, stranding, and entanglement in the subsequent processing. Therefore, the chain needs to be replaced regularly. Since the chain is inside the equipment, it can only be replaced by pulling it on the side of the equipment. However, the space here is small and large pulling equipment cannot enter. It can only be pulled by staff using pliers. This process has problems such as difficulty in separation and long time consumption. It is not only not conducive to ensuring production efficiency, but the pulling process will cause irreversible damage to the chain and is not conducive to controlling production costs.
