Description

Technical Field

[0001] The utility model relates to the technical field of tube core production of cable packaging films, in particular to a tube core fixed-length cutting device for cable packaging films. Background Art

[0002] A cable is a type of cable that can carry electricity and is composed of one or several groups of conductors. It is wrapped with an insulating protective layer on the outside. When the cables are stored or used, wrapping a protective packaging film on their surface can protect the insulating layer from damage due to bumps and friction to a certain extent. When multiple cables are set up simultaneously, the cables can be stored and organized by wrapping the packaging film on their surface to avoid loose winding of the cables.

[0003] The tube core used in the production of cable packaging film usually needs to be cut into a width that is suitable for the cable packaging film. The conventional cutting device usually cuts a single tube core and needs to measure before cutting. The overall operation takes a long time and is more laborious. Utility Model Content

[0004] The utility model aims to provide a tube core fixed-length cutting device for cable packaging film in view of the defects of the prior art, so as to solve the problems raised in the above-mentioned background technology.

[0006] The fixed-length component includes a support platform and an electric cylinder. The support platform is installed at the output end of the electric cylinder and slides up and down along the inner wall of the placement platform through a slide plate.

[0007] By adopting the above technical solution, it is convenient to place multiple tube cores at the same time, clamp them and cut them to a fixed length.

[0008] The cutting assembly includes a motor, a lead screw, a moving block, a laser cutting gun and a slide column. The lead screw is fixed to the output end of the motor, the moving block is transmission-mounted on the lead screw and slides laterally along the slide column arranged parallel to the lead screw, and the laser cutting gun is mounted on the moving block.

[0009] By adopting the above technical solution, the tube cores are cut one by one.

[0010] Ear plates are installed on both sides of the upper surface of the connecting plate, and springs are installed between the ear plates and the ear plates on the adjusting frame.

[0011] By adopting the above technical solution, after the adjustment frame is lifted up, the adjustment frame is pulled by the spring to move in a direction away from the limiting portion 2, thereby increasing the distance between the limiting portion 1 and the limiting portion 2.

[0012] The vertical section of the adjustment frame is in a right-angle trapezoidal structure as a whole.

[0013] By adopting the above technical solution, the tube cores of the limiting part 1 and the limiting part 2 are clamped by adjusting the frame to move up and down.

[0016] The beneficial effects of the tube core fixed length cutting device for cable packaging film of the utility model are:

[0017] Because the side surface of the adjustment frame that fits with the placement table is an inclined surface, the side surface of the adjustment frame on which the limiting part one is fixed approaches the limiting part two until the limiting part one and the limiting part two reduce the distance between them, thereby limiting the tube core, but the limiting part one and the limiting part two are not in contact with the outer wall of the tube core at this time. Then the electric cylinder is controlled to push and pull the support table up and down along the slide plate to a predetermined position. At this time, due to gravity, the bottom of the tube core is always supported by the support table, and the cutting position of the tube core is at the port of the laser cutting gun, waiting for cutting, and then the cylinder is driven to control the adjustment frame to move downward, so that the limiting part one and the limiting part two clamp the tube core. This device is convenient for placing multiple tube cores at the same time, clamping them and cutting them to a fixed length. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0024] The fixed-length assembly includes a support platform 9 and an electric cylinder 10. The support platform 9 is installed at the output end of the electric cylinder 10 and slides up and down along the inner wall of the placement platform 1 through a slide plate 101.

[0025] A notch is provided at the middle side of the upper end of the placement table 1, which can be used to place the tube core in the notch. By controlling the distance between the limiting portion 1 7 and the limiting portion 2 8, the tube core can be clamped. The limiting portion 1 7 and the limiting portion 2 8 have arc-shaped structures on opposite sides, so that when the tube core is placed, the placement area enclosed by the limiting portion 1 7 and the limiting portion 2 8 can limit the tube core to remain in a vertical state without tipping over.

[0026] The cutting assembly includes a motor 11, a lead screw 12, a moving block 13, a laser cutting gun 14 and a slide column 15. The lead screw 12 is fixed to the output end of the motor 11. The moving block 13 is installed on the lead screw 12 and slides horizontally along the slide column 15 parallel to the lead screw 12. The laser cutting gun 14 is installed on the moving block 13.

[0027] The laser cutting gun 14 is connected to an external power supply. When cutting the tube core, the laser cutting gun 14 is powered on, and the motor 11 drives the lead screw 12 to drive the moving block 13 to move laterally along the slide column 15. The laser cutting gun 14 cuts multiple tube cores one by one at the same time.

[0028] Ear plates are installed on both sides of the upper end surface of the connecting plate 3, and a spring 5 is also installed between the ear plate and the ear plate on the adjusting frame 6; after the adjusting frame 6 moves upward, in order to increase the distance between the limiting part 1 7 and the limiting part 2 8, the adjusting frame 6 can be moved in a direction away from the limiting part 2 8 by the pulling force of the spring 5.

[0029] The vertical cross-section of the adjusting frame 6 is a right-angled trapezoidal structure as a whole; the inclined surface of the adjusting frame 6 is in contact with the placing table 1, and a limiting part 7 is installed at the right-angle end surface of the adjusting frame 6. When moving downward, due to its inclined surface, the limiting part 1 7 will approach the position of the limiting part 2 8, and then the tube core is clamped by the limiting part 1 7 and the limiting part 2 8.

[0030] A slot 102 at the same height as the laser cutting gun 14 is provided on the side of the placement table 1, and a slot 2 103 is provided below the slot 102; the slot 102 is used for the laser cutting gun 14 to cut the tube core, and the slot 2 103 is convenient for removing the cut tube core.

[0031] Working principle: the tube cores are placed vertically one by one on the support platform 9 in the middle groove of the placement table 1, and the side edge of each tube core is correspondingly attached to the limiting part 2 8, and then the cylinder 2 is driven to pull the connecting plate 3 downward, and the connecting plate 3 presses down the adjusting frame 6 through the connecting arm 4. Because the side surface of the adjusting frame 6 that is attached to the placement table 1 is an inclined surface, at this time, the side surface of the adjusting frame 6 fixed with the limiting part 1 7 is close to the limiting part 2 8, until the limiting part 1 7 and the limiting part 2 8 reduce the distance between them, which can limit the tube core, but the limiting part 1 7 and the limiting part 2 8 are not attached to the outer wall of the tube core at this time, and then the electric cylinder 10 is controlled to push and pull the support platform 9 to move up and down along the slide 101 to the predetermined position. At this time, due to gravity, the bottom of the tube core is always supported by the support platform 9, and the cutting position of the tube core is at the port of the laser cutting gun 14, waiting for cutting; then the cylinder 2 is driven again to control the adjusting frame 6 to move downward, so that the limiting part 1 7 and the limiting part 2 8 clamp the tube core;

[0032] Then the driving motor 11 drives the moving block 13 to move along the slide column 15 through the lead screw 12, and controls the laser cutting gun 14 to cut the tube cores one by one. After the tube core cutting is completed, the electric cylinder 10 can be driven to drive the support table 9 to move downward, and the tube core can be removed from the support table 9;

[0033] Subsequently, the support platform 9 is pushed back to the previous predetermined position by the electric cylinder 10, and the air cylinder 2 is controlled to move the adjustment frame 6 upward, so that the limit part 1 7 and the limit part 2 8 release the clamping force on the tube core, so that the tube core falls onto the support platform 9 due to gravity, and then it is clamped by the limit part 1 7 and the limit part 2 8 to carry out the next round of cutting.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
