Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a driving device of a PET film frame component. Background Art

[0002] The PET film frame assembly can prevent the PET film from shaking up and down during transportation, ultimately ensuring that the PET film can be transported stably.

[0003] However, the existing film frame assembly is not applicable to different PET films. That is, the initial height position of the PET film during transportation may be relatively high or relatively low, which causes the PET film to still vibrate up and down during transportation, and its stability is relatively poor. Summary of the invention

[0004] The purpose of the utility model is to provide a PET film frame assembly with high applicability and compact structure in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A driving device for a PET film frame assembly, the PET mold frame assembly includes a frame and a flat plate body, the frame is U-shaped, the plate body is located at the U-shaped opening, and a channel for the PET film to pass stably is formed between the plate body and the U-shaped recess of the frame, and the driving device includes a screw rod, a connecting tube 1, a connecting tube 2, a connecting rod 1 and a connecting rod 2, the screw rod is laterally arranged and axially fixed at the U-shaped recess of the frame, the outer end of the screw rod extends out of the frame and a handle is connected to the outer end of the screw rod, the connecting tube 1 and the connecting tube 2 are respectively connected to the two ends of the screw rod, the connecting rod 1 and the connecting rod 2 are symmetrically arranged on the inner side of the frame, the two ends of the connecting rod 1 are respectively hinged to the connecting tube 1 and the plate body, and the two ends of the connecting rod 2 are respectively hinged to the connecting tube 2 and the plate body.

[0007] In the driving device of the PET film frame assembly, since the connecting rod 1 is connected to the plate body and the connecting tube 1, and the connecting rod 2 is connected to the plate body 2 and the connecting tube 2, after applying external force to rotate the screw rod, the connecting tube 1 and the connecting tube 2 can be moved on the screw rod, and the connecting rod 1 is dragged by the connecting tube 1, and the connecting rod 2 is dragged by the connecting tube 2, and finally the plate body is ensured to move up at the U-shaped notch of the frame.

[0008] After the initial height position of the plate body is changed, it can adapt to the height position of the PET film. Since the PET film is adjacent to the lower part of the plate body during transportation, the plate body can effectively block the PET film to prevent the PET film from shaking up and down significantly during transportation.

[0009] In the above-mentioned driving device of the PET film frame assembly, the two ends of the screw rod are respectively the connecting section 1 and the connecting section 2 of the threaded segment, the above-mentioned connecting tube 1 is threadedly connected to the first connecting section, and the above-mentioned connecting tube 2 is threadedly connected to the second connecting section, and the thread rotation directions of the above-mentioned connecting section 1 and the connecting section 2 are opposite.

[0010] Since the thread rotation directions of the connecting section 1 and the connecting section 2 are opposite, the connecting tube 1 and the connecting tube 2 can move closer to or away from each other during the rotation of the screw rod.

[0011] In the above-mentioned driving device of the PET film frame assembly, the upper part of the plate body has a protruding hinge part 1, the above-mentioned connecting rod 1 is arranged obliquely and a lower end of the connecting rod is hinged to the hinge part 1.

[0012] The hinge part 1 can enable the connecting rod 1 to be hinged to the plate body conveniently and stably.

[0013] In the above-mentioned driving device of the PET film frame assembly, the upper part of the plate body has a protruding hinge part 2, the above-mentioned connecting rod 2 is inclined and the lower end of the connecting rod 2 is hinged to the hinge part 2, the angle between the connecting rod 1 and the plate body is the same as the angle between the connecting rod 2 and the plate body, and the inclination directions of the connecting rod 1 and the connecting rod 2 are opposite.

[0014] The second hinged portion can enable the second connecting rod to be hinged to the plate body conveniently and stably.

[0015] In the above-mentioned driving device of the PET film frame assembly, there are two hinged parts one, and the two hinged parts one are opposite to the two sides of the connecting tube one. There are two connecting rods one, and the upper ends of the two connecting rods one are respectively hinged at the two sides of the connecting tube one, and the lower ends of the two connecting rods one are respectively hinged at the corresponding hinged parts.

[0016] The arrangement of the two hinged parts can effectively improve the connection stability and can also effectively prevent the board from flipping over.

[0017] In the above-mentioned driving device of the PET film frame assembly, the number of the hinged parts 2 is two, and the two hinged parts 2 are directly opposite to the two sides of the connecting tube 2. The number of the above-mentioned connecting rods 2 is two, and the upper ends of the two connecting rods 2 are respectively hinged at the two sides of the connecting tube 2, and the lower ends of the two connecting rods 2 are respectively hinged at the corresponding hinged parts 2.

[0018] The arrangement of the two hinged parts 2 can effectively improve the connection stability and also effectively prevent the board from flipping over.

[0019] In the above-mentioned driving device of the PET film frame assembly, a sliding friction assembly is provided between the plate body and the inner side of the frame to reduce the friction resistance therebetween.

[0020] When the plate body moves up and down along the frame, the friction resistance of the plate body can be effectively reduced through the sliding friction component.

[0021] In the above-mentioned driving device of the PET film frame assembly, the sliding friction assembly includes a recessed positioning hole at the end of the plate body, and a spring and a ball are arranged in the positioning hole. Under the elastic force of the spring, the ball part extends out of the plate body and abuts against the inner side of the frame.

[0022] Under the elastic force of the spring, the ball tends to extend out of the positioning hole. Since the end of the plate body is adjacent to the inner side of the frame, the ball that partially extends out of the plate body eventually stably rests against the inner side of the frame.

[0023] In the above-mentioned driving device of the PET film frame assembly, the above-mentioned positioning hole, spring and ball form a contact unit, the number of the contact units is several, and the several contact units are evenly distributed along the width direction of the plate end.

[0024] The shared load of multiple contact units further improves its stability.

[0025] In the above-mentioned driving device of the PET film frame assembly, the outer side of the frame is provided with a plug hole, a plug rod is detachably connected to the plug hole, and the above-mentioned handle has a tendency to abut against the plug rod.

[0026] Before turning the handle, remove the rod from the positioning hole, and after the position of the plate is determined, reinsert the rod into the positioning hole.

[0027] Since the position of the plug rod is fixed, the handle can be positioned once after each rotation, that is, the board body cannot be positioned at any position. The board body can only be positioned at several preset height positions.

[0028] Compared with the prior art, the driving device of the PET film frame assembly can adjust the initial height position of the plate body, thereby effectively improving the applicability of the PET film frame assembly.

[0029] At the same time, after the screw rod rotates, the connecting tube 1 and the connecting tube 2 move closer to or away from each other, so the action is stable and the structure is compact, and it has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS
