Description

Technical Field

[0001] The utility model belongs to the field of plastic bag processing, and particularly relates to an eccentric driving mechanism of a nylon plate for punching plastic bags. Background Technique

[0002] When punching plastic bags, a nylon plate is needed to support the plastic bags. During the punching process, the nylon plate is continuously impacted, and its surface will be worn after long-term use, so the nylon plate needs to be replaced.

[0003] At present, the nylon plate is usually detachably installed on the platform. Since the nylon plate cannot be displaced, the same part of the nylon plate is continuously impacted, resulting in local excessive wear and premature replacement.

[0004] Therefore, we propose an eccentric driving mechanism of a nylon plate for punching plastic bags to solve the above problems. Content of the Utility Model

[0005] Aiming at the problem that the nylon plate is usually detachably installed on the platform. Since the nylon plate cannot be displaced, the same part of the nylon plate is continuously impacted, resulting in local excessive wear and premature replacement, the utility model provides an eccentric driving mechanism of a nylon plate for punching plastic bags.

[0006] The solution adopted by the utility model to solve its technical problems is: an eccentric driving mechanism of a nylon plate for punching plastic bags, including a displacement plate, a power component, two displacement rods, two supporting plates and two parallel fixed plates. The two supporting plates are fixedly installed on the tops of the two fixed plates;

[0007] Two groups of parallel linear guides I are installed between the two fixed plates, and a sliding member I is slidably arranged on the linear guide I;

[0008] The displacement rod is higher than the fixed plate, and its two ends respectively extend to the outside of the two fixed plates. The fixed part of the displacement rod is fixedly installed on the sliding member I;

[0009] Linear guides II are respectively installed at the two ends of the displacement rod, and a sliding member II is slidably arranged on the linear guide II;

[0010] The displacement plate is fixedly installed on the tops of the four sliding members II and is located above the supporting plate. Two placement holes for placing the nylon plate are opened in the displacement plate, and the two placement holes respectively correspond to the two supporting plates;

[0011] The power component is installed on any one of the fixed plates and is connected to the displacement plate to drive the displacement plate to move back and forth, left and right.

[0012] Preferably, the linear guide I is a guide rod I, and the sliding member I is a sliding sleeve I.

[0013] Preferably, the second linear guide is the second guide rod, and the second sliding member is the second sliding sleeve.

[0014] Preferably, the power component is an eccentric wheel motor installed on any one of the fixing plates.

[0015] Preferably, a plurality of friction teeth are arranged around the placement hole.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. Under the combined action of the first linear guide, the first sliding member, the second linear guide, and the second sliding member, the displacement plate is stably supported. The displacement plate is driven by the eccentric wheel motor to move slightly forward, backward, left, and right. During the movement of the displacement plate, the two nylon plates are driven to move, and then the positions of the nylon plates are continuously changed, making the wear of the nylon plates more uniform, extending the service life of the nylon plates, and avoiding premature replacement due to local excessive wear.

[0018] 2. By arranging a plurality of friction teeth around the placement hole in the present utility model, during the forward and backward movement of the displacement plate, the nylon plate can be driven to rotate under the action of the friction teeth, making the wear of the nylon plate more uniform.

[0023] The present utility model will be further described below with reference to the drawings and embodiments.

[0024] Please refer to Figures 1-3 , the present utility model provides a technical solution for a nylon plate eccentric drive mechanism for punching plastic bags:

[0025] Embodiment 1:

[0026] According to Figures 1-3As shown in the figure, it includes a displacement plate 4, a power component, two displacement rods 33, two support plates 6, and two fixing plates 1 arranged in parallel. The two support plates 6 are fixedly installed on the tops of the two fixing plates 1.

[0027] Two groups of linearly guiding members 2 are installed between the two fixing plates 1 and are arranged in parallel. The linearly guiding member 2 is a guide rod 1. A sliding member 22 is slidably arranged on the linearly guiding member 2, and the sliding member 22 is a sliding sleeve 1.

[0028] The displacement rod 33 is higher than the fixing plate 1, and its two ends respectively extend to the outside of the two fixing plates 1 to prevent the fixing plate 1 from affecting the movement of the displacement rod 33. The fixed part of the displacement rod 33 is fixedly installed on the sliding member 22, so that the displacement rod 33 can move back and forth as the sliding member 22 moves.

[0029] Linear guiding members 31 are respectively installed at the two ends of the displacement rod 33. The linear guiding member 31 is a guide rod 2. A sliding member 32 is slidably arranged on the linear guiding member 31, and the sliding member 32 is a sliding sleeve 2.

[0030] The displacement plate 4 is fixedly installed on the tops of the four sliding members 32 and is located above the support plate 6. Under the combined action of the linear guiding member 2, the sliding member 22, the linear guiding member 31, and the sliding member 32, the displacement plate 4 is stably supported and can move back and forth, left and right. Two placement holes 41 for placing nylon plates are opened in the displacement plate 4. The two placement holes 41 respectively correspond to the two support plates 6. The support plates 6 are used to support the nylon plates so that the nylon plates will not sag.

[0031] The power component is an eccentric wheel motor 5 installed on any one of the fixing plates 1. The eccentric wheel of the eccentric wheel motor 5 is in frictional connection with the displacement plate 4. By driving the displacement plate 4 with the eccentric wheel motor 5, the displacement plate 4 moves slightly back and forth, left and right. During the movement of the displacement plate 4, the two nylon plates are driven to move, and then the positions of the nylon plates are continuously changed, making the wear of the nylon plates more uniform, extending the service life of the nylon plates, and avoiding premature replacement due to local excessive wear.

[0032] Embodiment 2:

[0033] On the basis of Embodiment 1, as Figure 3 shown, a plurality of friction teeth 42 are arranged in a ring in the placement hole 41. During the forward and backward movement of the displacement plate 4, the nylon plate can be driven to rotate under the action of the friction teeth 42, making the wear of the nylon plate more uniform.
