Description

Technical Field

[0001] The utility model relates to the technical field of reclaimers, in particular to a chain-breaking protection mechanism for reclaimers. Background Art

[0002] A reclaimer is an automated device used to take materials out of a hopper or storage device and transport them to downstream equipment or production lines. It is usually composed of a robotic arm, conveyor belt, vibrator, etc. It can be customized according to different material characteristics and production requirements. Reclaimers are widely used in food, medicine, chemical, electronics and other industries to improve production efficiency, reduce labor intensity and reduce human errors.

[0003] Due to the long working hours and heavy workload of the reclaimer, the chain (3) is damaged and there is a risk of breaking. If it breaks, it may cause worker injuries or equipment damage, and may also cause the production line to stop operating, resulting in a decrease in production efficiency.

[0004] Therefore, we propose a chain-breaking protection mechanism for a reclaimer to solve the above problems. Utility Model Content

[0007] Preferably, a squeeze button is fixedly connected to the bottom of the linkage piece, and the squeeze button is vertically perpendicular to the top of the control switch.

[0008] Preferably, an oil tank is fixedly connected to the surface of the machine body, a sliding layer is fixedly connected to the bottom of the extrusion block, a telescopic oil delivery hose is fixedly connected to the bottom of the oil tank, and the other end of the telescopic oil delivery hose is connected to the sliding layer.

[0009] Preferably, the sliding layer is made of polytetrafluoroethylene.

[0012] Preferably, two groups of limiting plates are fixedly connected to the surface of the sliding plate, and two groups of limiting grooves adapted to the limiting plates are formed on the inner wall of the placement box.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The spring pushes the sliding piece and the linkage rod at the bottom to drive the extrusion block and the chain to press against each other. When the chain breaks, the spring releases its elasticity to push the sliding piece and the linkage rod downward. When the linkage rod moves downward, it also drives the linkage piece downward. When the linkage piece moves downward, it also drives the extrusion button downward. The control switch is vertically perpendicular to the bottom of the extrusion button. The extrusion button presses the control switch to trigger the switch. The extrusion button is set to be made of rubber material to avoid damage to the control switch due to excessive impact when pressing the control switch. The control switch sounds an alarm and stops working as a whole. While providing safety protection, it can also remind the operator of the fault area, solving the problem that the chain of the reclaimer is damaged and there is a risk of breakage due to long-term work and heavy workload. If it breaks, it may cause worker injuries or equipment damage, and it will also cause the production line to stop running, resulting in reduced production efficiency.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a technical solution: a chain-breaking protection mechanism for a reclaimer, comprising a body 1 and two sets of gears 2 rotatably connected to the surface of the body 1, chains 3 being sleeved on the surfaces of the two sets of gears 2, a mounting plate 4 being fixedly connected to the surface of the body 1 to provide support for a placement box 5, a spring 6 being fixedly connected to the top wall of the inner cavity of the placement box 5, the spring 6 pushing a sliding sheet 7 and a linkage rod 8 at the bottom to drive an extrusion block 9 to press against the chain 3.

[0022] For details, please refer to Figure 1-4 When the chain 3 breaks, the spring 6 releases its elasticity to push the sliding piece 7 and the linkage rod 8 downward. When the linkage rod 8 moves downward, it also drives the linkage piece 10 downward. When the linkage piece 10 moves downward, it also drives the squeezing button 12 downward. The control switch 11 is vertically perpendicular to the squeezing button 12. The squeezing button 12 presses the control switch 11 to trigger the switch. The squeezing button 12 is set to be made of rubber material to avoid excessive impact when pressing the control switch 11, which may cause damage to the control switch 11. The control switch 11 issues an alarm and stops working as a whole. While providing safety protection, it can also remind the operator of the fault area.

[0023] For details, please refer to Figure 1-4 A sliding layer 14 is fixedly connected to the bottom of the extrusion block 9, and the sliding layer 14 and the chain 3 are pressed tightly. The sliding layer 14 is set to a polytetrafluoroethylene material, which can effectively absorb grease and will not affect the rotation of the chain 3. Lubricating oil is added to the sliding layer 14 through an oil tank 13 fixedly connected to the surface of the body 1 and a telescopic oil delivery hose 15 fixedly connected to the bottom of the oil tank 13, which ensures that the chain 3 rotates smoothly while also being able to maintain the chain 3 and extend the service life of the chain 3.

[0024] Working principle: the surface of the machine body 1 is fixedly connected with a mounting plate 4 to provide support for the placement box 5, and the top wall of the inner cavity of the placement box 5 is fixedly connected with a spring 6. The spring 6 pushes the sliding piece 7 and the linkage rod 8 at the bottom to drive the extrusion block 9 to press against the chain 3. When the chain 3 breaks, the spring 6 releases its elasticity to push the sliding piece 7 and the linkage rod 8 downward. When the linkage rod 8 moves downward, it also drives the linkage piece 10 downward. When the linkage piece 10 moves downward, it also drives the extrusion button 12 downward. The control switch 11 is vertically perpendicular to the bottom of the extrusion button 12. The extrusion button 12 presses the control switch 11 to trigger the switch. The extrusion button 12 is set to be made of rubber material to avoid excessive impact when pressing the control switch 11, which may cause damage to the control switch 11. The control switch 11 sends an alarm and stops working as a whole. , while providing safety protection, it can also remind the operator of the fault area. A sliding layer 14 is fixedly connected to the bottom of the extrusion block 9, and the sliding layer 14 and the chain 3 are tightly pressed. The sliding layer 14 is set to a polytetrafluoroethylene material, which can effectively absorb grease and will not affect the rotation of the chain 3. Lubricating oil is added to the sliding layer 14 through the oil tank 13 fixedly connected to the surface of the body 1 and the telescopic oil delivery hose 15 fixedly connected to the bottom of the oil tank 13. While ensuring the smooth rotation of the chain 3, the chain 3 can also be maintained to extend the service life of the chain 3, and solves the problem that the chain 3 is damaged and there is a risk of breakage due to long-term work and heavy workload of the reclaimer. If it breaks, it may cause injuries to workers or damage to equipment, and it will also cause the production line to stop running, resulting in a decrease in production efficiency.
