Description

Technical Field

[0001] The present invention belongs to the field of rubber gripping devices, and particularly relates to a composite-function feeding rubber-gripping fixture. Background Art

[0002] During the tire production process, in the semi-component production workshop, processes such as extrusion and calendering often require the continuous rubber sheets stored in stacks to be unwound and introduced onto the feeding conveyor belt to enter the automated production line. Currently, in the prior art, this operation is usually achieved by workers manually grasping the joints of the rubber sheets for feeding. This process has a large labor intensity and low work efficiency. Due to the small space for manual grasping, the risk is extremely high, and it hinders the automation process of the production line, which also results in the inability to guarantee the economic benefits of the enterprise. In addition, the continuous rubber sheets in stacks have different thicknesses from different manufacturers due to process effects, and their elasticity and toughness are greatly affected by the environment. Therefore, the grasping difficulty is relatively large. The existing rubber-gripping manipulators have a single function, and the deficiencies in technology and structure lead to frequent malfunction or inability to effectively adapt to the shape and thickness changes of the rubber sheets during rubber gripping, unable to meet the target requirements. This not only affects the normal use of the equipment and production efficiency but also affects the automated production efficiency of the entire production line. Summary of the Invention

[0003] In view of this, the present invention aims to propose a composite-function feeding rubber-gripping fixture to solve the above deficiencies.

[0004] To achieve the above object, the technical solution of the present invention is realized as follows:

[0036] The fixed frame 7 includes a top plate and four side plates. The top plate and the four side plates enclose a frustum structure, and a connecting seat 4 is fixedly connected to the upper surface of the top plate.

[0037] The working process of this embodiment is as follows:

[0038] In the lateral needle punching glue grabbing mechanism 1, the lateral needle punching driving cylinder 11 drives the lateral needle punching fixing seat 13 fixed with the lateral needles 14 to lift all the needles in the lateral needle punching glue grabbing mechanism 1. At the same time, the specifications of the lateral needles 14 are adjusted or replaced in advance according to the size of the continuous film stacked and stored. The position of the lateral needles 14 can also be finely adjusted by adjusting the backing plate 12 of the lateral needle punching mechanism cylinder.

[0039] The central vertical needle punching glue grabbing mechanism 3 drives the central vertical needle punching fixing seat 33 fixed with the central vertical needles 34 through the central vertical needle punching driving cylinder 31 and lifts the central vertical needles 34. At the same time, the specifications of the central vertical needles 34 can be adjusted or replaced in advance according to the size of the continuous film stacked and stored.

[0040] In the cat's paw glue grabbing mechanism 2, the cat's paw glue grabbing mechanism driving cylinder 21 drives the connecting rod 25, and the connecting rod 25 drives the cat's paw hook knife 26 to move through a pedestal bearing. The cat's paw hook knife 26 is combined and connected through a cat's paw hook knife blade 261 and a cat's paw hook knife seat 262, and the specifications of the cat's paw hook knife blade 261 can be adjusted according to the size of the continuous film stacked and stored.

[0041] Before the cat's paw glue-grabbing mechanism 2 works, the driving cylinder 21 of the cat's paw glue-grabbing mechanism contracts and swings under the action of two fixed seats 22 and two rotating frames 23, so as to lift the cat's paw hook knife blade 261 in the cat's paw glue-grabbing mechanism 2.

[0042] When the composite function feeding glue-grabbing fixture starts to grab the film, the fixed frame bottom plate 5 contacts the film first. At this time, the suction cup 65 in the suction cup glue-grabbing mechanism 6 contacts the film, and under the action of the spring 63, the suction cup 65 in the suction cup glue-grabbing mechanism 6 fits with the film. Then, the lateral needle glue-grabbing mechanism 1 drives the lower lateral needle 14 to extend under the drive of the lateral needle driving cylinder 11. At this time, the film is basically fixed under the action of the lateral needle glue-grabbing mechanism 1. Then the central vertical needle glue-grabbing mechanism 3 starts to act, and the central vertical needle 34 is inserted into the film under the drive of the central vertical needle driving cylinder 31. At this time, the film is basically fixed under the action of the needles, and the suction cup glue-grabbing mechanism 6 starts to act, and the suction cup 65 acts to fix the film. In order to further ensure that the film can be effectively grabbed, then the cat's paw glue-grabbing mechanism driving cylinder 21 in the cat's paw glue-grabbing mechanism 2 extends, and the cat's paw hook knife 26 hooks into the film under the drive of the connecting rod 25, so as to realize the grabbing of the film. Finally, the film is grabbed, and the composite function feeding glue-grabbing fixture completes the glue-grabbing action.

[0043] In the composite function feeding glue-grabbing fixture, the lateral needle glue-grabbing mechanism 1, the central vertical needle glue-grabbing mechanism 3, the suction cup glue-grabbing mechanism 6 and the cat's paw glue-grabbing mechanism 2 can also be applied individually or randomly combined according to the size specifications of the continuous film (raw material) stored in stacks and the physical properties of the film, so as to realize the effective grabbing of the film.

[0044] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
