TECHNICAL FIELD

[0001] The application relates to the technical field of plastic bag production, in particular to a clamping mechanism suitable for plastic bag plane transfer. BACKGROUND

[0002] Plastic bags are essential packaging products in people's daily life, and in order to facilitate users to meet the actual needs, the plastic bag products can be carried through the mechanism in the production process to meet the needs in the subsequent process. For example, the clamping mechanism special for plastic bag bundling disclosed in CN209567134U, but when the device is not used or the staff needs to maintain the device, the staff is not convenient to move the device, which increases the difficulty of the staff maintenance, also increases the limitation of the device use, and reduces the working efficiency of the device.

[0003] The existing plastic bag plane transfer clamping mechanism has small direct contact area between the clamping mechanism and the plastic bags to be transferred, and the clamping force is not enough. When the device works, the plastic bag raw materials may fall off during the transfer, which not only reduces the working efficiency of the device, but also delays the construction period, and more likely causes damage to the plastic bag raw materials, which is not conducive to the economic benefit of the factory.

[0004] In view of the above problems, it is urgent to make innovative design on the basis of the original plastic bag plane transfer clamping mechanism. SUMMARY

[0005] The application aims to provide a clamping mechanism suitable for plastic bag plane transfer, to solve the problems that the device is not convenient to move when it is not used or the staff needs to maintain the device, which increases the difficulty of the staff maintenance, also increases the limitation of the device use, and the direct contact area between the clamping mechanism and the plastic bags to be transferred is small and the clamping force is not enough.

[0006] To achieve the above purpose, the application provides the following technical scheme: a clamping mechanism suitable for plastic bag plane transfer, comprising:

[0007] A support column is provided with an installation plate fixedly installed on the upper surface of the support column, a linear single-axis robot is movably installed on the lower surface of the installation plate, a servo motor capable of controlling displacement is fixedly installed on the left side of the linear single-axis robot, and a displacement sliding table is fixedly installed on the surface of the linear single-axis robot. When the staff needs to move the linear single-axis robot on the installation plate, the servo motor can be started;

[0008] A clamping structure is movably installed on the displacement sliding table, and a connecting shaft is movably installed in the clamping structure.

[0009] The height-adjustable foot cup is internally movably mounted with a long pin, and the surface of the long pin is sleeved with a roller facilitating the movement of the device by the staff, which facilitates the staff to move the device as a whole, facilitates the quick movement to the working position, and also facilitates the maintenance of the device, reduces the limitation of the device, and improves the working efficiency of the device.

[0010] Preferably, the clamping structure further comprises a mounting block:

[0011] The mounting block is fixedly installed with a cylinder on the surface, and the lower surface of the cylinder is fixedly installed with an upper clamping jaw, and the lower surface of the mounting block is fixedly installed with a lower clamping jaw corresponding to the upper clamping jaw. When the upper clamping jaw is close to the lower clamping jaw under the action of the cylinder, the upper clamping jaw and the lower clamping jaw finally clamp and fix the plastic bag raw materials to be transported;

[0012] The cylinder is fixedly installed with a traction rope on the surface, and the cylinder drives the connecting shaft to rotate counterclockwise through the traction rope, the connecting shaft drives the micro gear to rotate counterclockwise, and then the micro gear drives the support plate to move left in the lower clamping jaw through the micro rack, thereby increasing the contact area between the plastic bag material and the device during clamping and fixing, optimizing the stability of the device during work, and improving the working efficiency of the device.

[0013] Preferably, the lower clamping jaw is fixedly installed with a torsion spring for elastic return inside, and the other side of the torsion spring is fixedly connected with the connecting shaft, and the surface of the connecting shaft is fixedly connected with the traction rope. When the traction rope drives the connecting shaft to rotate counterclockwise, the connecting shaft makes the torsion spring in a stretched state. When the traction rope returns to the original position and the connecting shaft loses the pulling force, the torsion spring rotates to make the connecting shaft rotate clockwise, and finally the micro gear makes the micro rack return to the original position.

[0014] Preferably, the lower clamping jaw is fixedly installed with a support plate with an inclined surface inside, and the lower clamping jaw is provided with a first spring for elastic return, and the other side of the first spring is fixedly connected with a protrusion for limiting the movement distance of the support plate. When the support plate is pushed by the micro rack and moves left in the lower clamping jaw, the support plate makes the first spring in a stretched state through the protrusion, and the protrusion does not make the support plate move out of the lower clamping jaw, thereby improving the stability of the device. When the micro rack returns to the original position and the support plate loses the pushing force of the micro rack, the first spring brings the support plate back to the original position through the protrusion, thereby facilitating the use of the device next time.

[0015] Preferably, the protrusion is fixedly connected with the support plate, and the outer wall of the support plate is attached to the inner wall of the lower clamping jaw. The outer wall of the support plate is attached to the inner wall of the lower clamping jaw, so that the support plate only moves in the horizontal direction when it is stressed.

[0016] Preferably, the surface of the connecting shaft is fixedly installed with a micro gear, the surface of the micro gear is engaged with a micro rack, the surface of the micro rack is fixedly installed with a sliding block, the sliding blocks are symmetrically distributed about the center of the micro rack, when the connecting shaft drives the micro gear to rotate, the micro gear drives the micro rack to move to the left, and the symmetrically distributed sliding blocks on both sides of the micro rack enable the micro rack to only move in the horizontal direction.

[0017] Preferably, the inside of the height-adjustable foot cup is movably installed with an inner tube, the inside of the height-adjustable foot cup is provided with a clamping groove, and the inner tube is fixedly connected with the long pin, when the staff adjusts the height-adjustable foot cup, the inner tube rises in the inside of the height-adjustable foot cup, the inner tube drives the long pin and the roller to rise in the inside of the height-adjustable foot cup, when the roller enters the inside of the height-adjustable foot cup and is not in contact with the ground, the staff can use the device with peace of mind.

[0018] Preferably, the inside of the long pin is fixedly installed with a second spring for elastic reset, the other side of the second spring is fixedly installed with a clamping block corresponding to the clamping groove, and the inside of the long pin is provided with a deep groove, when the long pin rises in the inside of the height-adjustable foot cup, the inclined surface of the clamping block is pressed by the inner wall of the height-adjustable foot cup, the clamping block moves to the inside of the deep groove, at this time, the long pin and the height-adjustable foot cup are disengaged, when the long pin continues to rise in the inside of the height-adjustable foot cup, the long pin drives the roller to rise, at this time, the device cannot roll on the bottom surface and can work normally, the safety of the device is improved, and at this time, the clamping block enables the second spring to be in a compressed state.

[0019] Preferably, the upper surface of the clamping block is attached to the inner wall of the long pin, and the clamping blocks are symmetrically distributed about the center of the long pin, the upper surface of the clamping block is attached to the inner wall of the long pin, so that the clamping block only moves in the horizontal direction, and the symmetrically distributed clamping blocks optimize the clamping effect of the device and improve the safety of the device.

[0020] Compared with the prior art, the device has the advantages that the clamping mechanism is suitable for the planar transfer of plastic bags.

[0021] 1. This clamping mechanism for flat transfer of plastic bags allows the inner tube to rise inside the height-adjustable foot cup when the operator stretches it. At this time, the inclined surface of the locking block is pressed against the inner wall of the height-adjustable foot cup, causing the inner tube to move into the deep groove. Meanwhile, the long pin and the height-adjustable foot cup are not engaged. The long pin is driven by the inner tube and rises inside the height-adjustable foot cup. Simultaneously, the roller also rises inside the height-adjustable foot cup. This ensures the device remains stable during operation. When not in operation, the operator can quickly move the device using the roller. When maintenance or relocation is needed, the inner tube descends inside the height-adjustable foot cup. Upon returning to its original position, the locking block moves out of the deep groove under the action of the second spring, eventually re-entering the corresponding slot. The long pin and the height-adjustable foot cup re-engage, and the roller re-contacts the ground, facilitating movement of the device and improving its efficiency.

[0022] 2. In this gripping mechanism for flat transfer of plastic bags, when the cylinder in the gripping structure drives the upper gripper to descend, the cylinder drives the connecting shaft to rotate counterclockwise via the traction rope. When the connecting shaft rotates counterclockwise, it drives the micro gear to rotate counterclockwise. The micro gear drives the micro rack to move to the left, and the micro rack pushes the support plate, causing the support plate to also move to the left inside the lower gripper. The cooperation between the support plate and the lower gripper increases the contact area of ​​the device when gripping materials, thereby optimizing the gripping stability and improving the working efficiency of the device. At this time, the protrusion keeps the first spring in a stretched state. After the traction rope 504 returns to its original position, the connecting shaft loses tension, and the torsion spring drives the connecting shaft to rotate clockwise. At this time, the micro gear rotates clockwise, causing the micro rack to move to the right inside the lower gripper. At this time, the right side of the support plate loses the pushing force, and the first spring drives the support plate back to its original position via the protrusion. At this time, all parts inside the device return to their original positions, facilitating the next use of the device. Attached Figure Description

[0042] When the staff member pulls the height-adjustable foot cup 3 at the lower end of the supporting column 1, the inner tube 14 rises in the inside of the height-adjustable foot cup 3, at this time, the inclined surface of the symmetrically distributed clamping block 19 is pressed by the inner wall of the height-adjustable foot cup 3, so that the clamping block 19 moves to the inside of the deep groove 20 on the long pin 16, when the clamping block 19 moves out of the clamping groove 15, at this time, the second spring 18 is in a compressed state, and the long pin 16 and the height-adjustable foot cup 3 are not in a clamping state, the long pin 16 is driven by the inner tube 14 to rise in the inside of the height-adjustable foot cup 3, at this time, the roller 17 also rises in the inside of the height-adjustable foot cup 3, and the roller 17 finally does not contact the bottom surface, that is, during work, the device remains stable, and when the device is not in work, the staff member can quickly move the device through the roller 17, when the staff member needs to maintain or move the device, the inner tube 14 is lowered in the inside of the height-adjustable foot cup 3, and finally returns to the original position, at this time, the clamping block 19 moves to the outside of the deep groove 20 under the action of the second spring 18, and finally the clamping block 19 reenters the corresponding clamping groove 15, and the long pin 16 and the height-adjustable foot cup 3 are in the clamping state again, which is convenient for the staff member to move the device.

At this time, the right side of the support plate 6 loses its pushing force, and the first spring 7, through the protrusion 8, drives the support plate 6 back to its original position. At this time, all parts inside the device return to their original positions, making it convenient for the next use of the device.
