Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment for metal can covers, in particular to a crocodile-type layer pulling mechanism. Background Art

[0002] During transportation, the lids of cans are generally arranged one by one into long strips, then wrapped with film to form cylindrical strips. The wrapped strips are then stacked on pallets in sequence. After multiple layers are stacked, they form chops. During processing, the top strip is pushed out a small distance through a pushing mechanism, and then the strip is clamped by a clamping mechanism and pulled out to the conveyor belt.

[0003] The traditional clamping mechanism generally includes an upper clamping plate and a lower clamping plate. The upper driving module drives the upper clamping plate to move up and down, and the lower driving module drives the lower clamping plate to move up and down, and then the material strip is clamped by the cooperation of the upper and lower clamping plates. The defect of this design is: since both the upper and lower clamping plates require driving modules to drive, more driving modules need to be used, resulting in high equipment costs. Secondly, sufficient space needs to be reserved for the stroke of the upper and lower clamping plates, which causes the clamping mechanism to occupy a larger space. In this context, the applicant is committed to researching a crocodile-type layer pulling mechanism, further improving the existing structure, further reducing the number of driving modules used, reducing equipment costs to a certain extent, and further reducing the occupied space. Utility Model Content

[0004] The purpose of the present invention is to further reduce the number of drive modules used, reduce equipment costs to a certain extent, and further reduce occupied space.

[0005] In order to achieve the above purpose, the technical solutions adopted by the present invention are as follows:

[0006] A crocodile-type layer pulling mechanism includes a transverse movement mechanism, a fixed clamp, a movable clamp, a hinge and a drive module. The transverse movement mechanism drives the fixed clamp to move back and forth laterally. The fixed clamp and the movable clamp are hinged to each other through a hinge, and the fixed clamp and the movable clamp cooperate with each other. The drive module drives the movable clamp to rotate with the hinge as the central axis, thereby cooperating with the fixed clamp to clamp or open each other.

[0007] Furthermore, the driving module includes a cylinder and a toggle block, the outer shell of the cylinder is fixedly arranged on the fixed clamp, one end of the toggle block is fixed on the movable clamp, and the other end of the toggle block is hinged to the telescopic rod of the cylinder.

[0008] Furthermore, a sliding groove is provided on the toggle block, a sliding column is slidably provided in the sliding groove, and the sliding column is fixedly connected to the telescopic rod of the cylinder.

[0009] Furthermore, the transverse movement mechanism includes a motor, a screw assembly, a slider and a slide rail. The motor drives the screw assembly to work, and the screw assembly drives the slider to move back and forth along the slide rail. The slider is fixedly connected to the fixing clamp.

[0010] Furthermore, the transverse movement mechanism further includes a connecting rod, the slider is fixedly connected to the connecting rod, and the connecting rod is fixedly connected to the fixing clamp.

[0011] Furthermore, an outer curling edge is provided on one end of the fixed clamp away from the hinge, and an inner curling edge is provided on one end of the movable clamp away from the hinge.

[0012] The beneficial effects of the present invention are as follows: the present invention hinges the fixed clamp and the movable clamp together through a hinge, and drives the movable clamp to rotate with the hinge as the center axis through the driving module, and then cooperates with the fixed clamp to clamp or open each other, so that it is only necessary to drive the movable clamp to rotate, and the movable clamp can cooperate with the fixed clamp to achieve the clamping or opening action. Since it is only necessary to drive the movable clamp to rotate and there is no need to drive the fixed clamp to move, the present invention saves the number of driving modules and reduces the equipment cost to a certain extent; on the other hand, the driving module of the present invention only needs to drive the movable clamp to rotate with the hinge as the center axis, and the fixed clamp does not need to be displaced relative to the movable clamp. Compared with the prior art, the present invention saves more travel space, thereby further reducing the internal occupied space of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 3The crocodile-type layer pulling mechanism shown includes a transverse movement mechanism 1 , a fixed clamp 2 , a movable clamp 3 , a hinge 4 and a driving module 5 .

[0022] The transverse movement mechanism 1 drives the fixed clamp 2 to move back and forth laterally. The fixed clamp 2 and the movable clamp 3 are hinged to each other through the hinge 4, and the fixed clamp 2 and the movable clamp 3 cooperate with each other. The driving module 5 drives the movable clamp 3 to rotate with the hinge 4 as the central axis, and then cooperates with the fixed clamp 2 to clamp or open each other.

[0023] The present invention only needs to drive the movable clamp 3 to rotate back and forth within a certain angle range, and does not need to drive the fixed clamp 2 to move, so that the present invention saves the number of drive modules 5 and reduces the equipment cost to a certain extent. On the other hand, the fixed clamp 2 of the present invention does not need to be displaced relative to the movable clamp 3. Compared with the prior art, the present invention saves more travel space, thereby further reducing the internal occupied space of the equipment.

[0024] The transverse movement mechanism 1 includes a motor 11, a screw assembly, a slider 12, a slide rail 13, and a connecting rod 14. The motor 11 drives the screw assembly to work, and the screw assembly drives the slider 12 to move back and forth along the slide rail 13. The slider 12 is fixedly connected to the connecting rod 14, and the connecting rod 14 is fixedly connected to the fixing clamp 2.

[0025] The driving module 5 includes a cylinder 51 and a toggle block 52 . The outer shell of the cylinder 51 is fixedly disposed on the fixed clamp 2 , and one end of the toggle block 52 is fixed on the movable clamp 3 .

[0026] The other end of the toggle block 52 is hinged to the telescopic rod of the cylinder 51. In this embodiment, the more specific structure is: a slide groove 521 is provided on the toggle block 52, and a slide column is slidably provided in the slide groove 521. The slide column is fixedly connected to the telescopic rod of the cylinder 51. The design of the slide groove 521 can prevent interference.

[0027] An outer curling edge 21 is provided at the end of the fixed clamp 2 away from the hinge 4, and an inner curling edge 31 is provided at the end of the movable clamp 3 away from the hinge 4. The outer curling edge 21 can prevent the material strip from being punctured when clamping the material strip, and the inner curling edge 31 can better bite the material strip after clamping the material strip.

[0028] The working principle of the present invention is as follows: when loading the material strips on the material chop, the external pushing mechanism is used to push out a small section of the material strips on the top layer, and then the driving module 5 drives the movable clamp 3 to open, and the transverse movement mechanism 1 drives the fixed clamp 2 to move transversely to the material strips on the top layer, and the driving module 5 drives the movable clamp 3 to close, and cooperates with the fixed clamp 2 to bite the small section of the material strips that have been pushed out, and then the transverse movement mechanism 1 drives the fixed clamp 2 to move transversely to above the conveyor belt, and finally the driving module 5 drives the movable clamp 3 to open again, so that the material strips fall onto the conveyor belt, and the loading operation of the material strips is completed.

[0029] The above disclosure is only a preferred embodiment of the present invention and cannot be used to limit the scope of protection of the present invention. Therefore, equivalent changes made within the scope of the patent application of the present invention are still within the scope covered by the present invention. The above does not impose any limitation on the technical scope of the present invention.
