Description

Technical Field

[0001] This utility model belongs to the field of transfer equipment technology, specifically relating to a transfer device for processing protective film. Background Technology

[0002] Protective film is often rolled up on the outside of a roll for transport in a cylindrical form. Most existing protective film transport methods involve stacking the cylindrical film on a trolley and then moving it by pushing the trolley. However, the shaking of the trolley during transport can cause friction damage between the protective films, resulting in losses. Some methods use pressure plates or straps to secure the protective film, but these are in direct contact with the film and can still cause wear during the securing process, affecting product quality. Utility Model Content

[0003] The purpose of this invention is to provide a transfer device for processing protective film, so as to solve the problem that existing transfer devices for processing protective film are prone to friction damage to the protective film during transfer.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A transfer device for processing protective film includes a base and two vertical plates symmetrically slidably connected to the base. Multiple sets of through holes are provided on the two vertical plates, and a connecting assembly is slidably connected within at least one set of through holes. The connecting assembly includes a slide cylinder and multiple top frames that slidably penetrate the sidewall of the slide cylinder. The multiple top frames are evenly arranged along the circumference of the slide cylinder. A slide frame is slidably provided inside the slide cylinder. Each top frame has a slide groove. A second connecting rod is connected between each top frame and the slide frame. A first connecting rod is rotatably connected to the middle of each second connecting rod. One end of each first connecting rod is rotatably connected to the slide cylinder, and the other end of each first connecting rod is slidably engaged in the multiple slide grooves.

[0008] Preferably, a first double-ended screw is rotatably connected to the base, and two vertical plates are respectively screwed onto the two ends of the first double-ended screw.

[0009] Preferably, a third motor is fixedly installed on the base, and the output shaft of the third motor is fixedly connected to one end of the first double-ended screw.

[0010] Preferably, both vertical plates are slidably connected to sliders on their inner sides, both sliders are fixedly mounted with hydraulic push rods, and both hydraulic push rods are fixedly connected to clamping components at their tops.

[0011] Preferably, a second motor is fixedly installed on one side of the vertical plate, and a first lead screw is fixedly connected to the output shaft of the second motor, with the slider screwed to the outside of the first lead screw.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] (1) This utility model is provided with a connecting component. By placing the protective film wound on the outside of the roll between two vertical plates, the slide tube is inserted into the roll inside the protective film through the through hole, and multiple top brackets are extended into the roll. The first connecting rod and the second connecting rod are rotated by sliding the slide, thereby pushing the top brackets against the inner wall of the roll inside the protective film, thus fixing the protective film. The protective film does not come into contact with other structures and there is no wear. In addition, the sliding distance of the slide can control the distance that the first connecting rod and the second connecting rod push the top brackets, which can be used to fix the protective film wound on the outside of rolls of different sizes, increasing practicality.

[0017] (2) The present invention is provided with a second double-headed screw and a vertical plate. The rotation of the second double-headed screw causes the two vertical plates to slide relative to each other, thereby changing the distance between the two vertical plates, so that protective films of different widths can be fixed, which facilitates subsequent transportation operations and increases practicality.

[0018] (3) The present invention is provided with a slider, a hydraulic push rod and a clamping assembly. The position of the clamping assembly is controlled by the sliding of the slider along the first lead screw and the extension and retraction of the hydraulic push rod. In this way, the clamping assembly can clamp and transport the roll of protective film on the external processing equipment, thereby realizing the automatic transport of the protective film to the transfer device, so as to reduce the labor intensity of workers and improve work efficiency.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-7 As shown, this utility model provides the following technical solution:

[0029] A transfer device for processing protective film includes a base 1 and two vertical plates 3 symmetrically slidably connected to the base 1. The two vertical plates 3 have a plurality of corresponding through holes 6. A connecting component is slidably connected in at least one set of through holes 6. The connecting component includes a slide cylinder 4 and a plurality of top frames 5 slidably penetrating the side wall of the slide cylinder 4. The plurality of top frames 5 are evenly arranged around the circumference of the slide cylinder 4. A slide frame 23 is slidably provided in the slide cylinder 4. A slide groove 22 is provided on each top frame 5. A second connecting rod 19 is connected between each top frame 5 and the slide frame 23. A first connecting rod 18 is rotatably connected to the middle of each second connecting rod 19. One end of each first connecting rod 18 is rotatably connected to the slide cylinder 4. The other end of each first connecting rod 18 is slidably engaged in the plurality of slide grooves 22.

[0030] A baffle 26 is fixedly connected to one side of the slide cylinder 4. A second lead screw 24 is rotatably passed through the baffle 26, and the slide 23 is screwed to the outside of the second lead screw 24. A handle 21 is fixedly connected to one end of the second lead screw 24.

[0031] Multiple guide grooves 20 are provided on the outer side of the slide cylinder 4, and multiple protrusions that slide in cooperation with the multiple guide grooves 20 are fixed in the through hole 6.

[0032] Based on the disclosed structure above, during the transfer of the protective film:

[0033] The protective film is often wound around the outside of the roll to form a tube on the external processing equipment to facilitate the transfer of the protective film. Therefore, during the transfer, the tubular protective film and the inner roll should be placed together between two vertical plates 3. First, the two vertical plates 3 need to be moved on the base 1 according to the width of the protective film and the roll. Then, the roll is moved between one set of through holes 6. Then, the sliding cylinders 4 of the two connecting components are inserted into the two through holes 6 from both sides of the vertical plate 3, and one end of the sliding cylinder 4 with the top bracket 5 is inserted into the roll until the baffles 26 of the two connecting components abut against the outside of the two vertical plates 3. At this time, multiple top brackets 5 are located inside the roll. At the same time, when the sliding cylinder 4 is inserted into the through hole 6, multiple protrusions in the through hole 6 slide and engage with multiple guide grooves on the outside of the sliding cylinder 4 to prevent the sliding cylinder 4 from rotating.

[0034] Then, rotating the handle 21 drives the second lead screw 24 to rotate, causing the screw-connected slide 23 to move along the second lead screw 24 away from the baffle 26. At the same time, the slide 23 drives the end of the second connecting rod 19 to approach the end of the first connecting rod 18 inside the slide cylinder 4, causing the middle parts of the first connecting rod 18 and the second connecting rod 19 to rotate relative to each other. This causes the other end of the first connecting rod 18 to slide in the groove 22 on the top frame 5, thereby causing the top frame 5 to extend outward. This causes multiple top frames 5 evenly arranged on the outer circumference of the slide cylinder 4 to simultaneously press against the inner wall of the roll inside the protective film, thereby fixing the protective film. Then, the protective film is transferred by pushing the base 1. During the fixing and transfer process, the protective film does not come into contact with any other structure, eliminating the risk of wear and tear on the protective film and ensuring its quality.

[0035] In addition, the movement distance of the top frame 5 can be controlled according to the movement distance of the carriage 23, which can be used to fix the protective film on the outside of the roll of different sizes, increasing practicality; furthermore, during a single transfer process, multiple sets of through holes 6 at different distances can be selected, which can transfer tubular protective films of different diameters, and fix as many tubular protective films as possible without contact between adjacent tubular protective films, so as to improve transfer efficiency.

[0036] Regarding the movement of the vertical plate, the following structure is preferred:

[0037] A first double-ended screw 16 is rotatably connected to the base 1, and two vertical plates 3 are respectively screwed onto the two ends of the first double-ended screw 16;

[0038] A third motor 17 is fixedly installed on the base 1, and the output shaft of the third motor 17 is fixedly connected to one end of the first double-headed screw 16.

[0039] As can be seen from the above, by starting the third motor 17 to drive the first double-ended screw 16 to rotate, the two vertical plates 3 move closer to the center along the first double-ended screw 16, thereby shortening the distance between the two vertical plates 3; conversely, by starting the third motor 17 to drive the first double-ended screw 16 to rotate in the opposite direction, the distance between the two vertical plates is increased, thus facilitating the fixing and transfer of protective films of different widths, while ensuring that the top block 5 in the connecting assembly can extend into the drum. In addition, the bottom of the two vertical plates 3 is preferably provided with dovetail blocks, and the base 1 is provided with dovetail grooves that slide with the dovetail blocks, thereby ensuring that the vertical plates 3 can move smoothly on the base 1.

[0040] In addition, regarding the handling of the protective film and the roll, the following structure is preferred:

[0041] Both vertical plates 3 are slidably connected to sliders 12 on their inner sides, and both sliders 12 are fixedly mounted with hydraulic push rods 10. Both hydraulic push rods 10 are fixedly connected to their tops with clamping components.

[0042] A second motor 13 is fixedly installed on one side of the vertical plate 3. A first lead screw 11 is fixedly connected to the output shaft of the second motor 13. A slider 12 is screwed onto the outside of the first lead screw 11.

[0043] The clamping assembly includes a slide block 8 fixedly connected to the top of the hydraulic push rod 10 and two V-shaped clamping blocks 7 symmetrically slidably connected inside the slide block 8. A second double-ended screw 25 is rotatably connected inside the slide block 8, and the two V-shaped clamping blocks 7 are respectively screwed to the two ends of the second double-ended screw 25.

[0044] A first motor 9 is fixedly installed on one side of the slide block 8, and the output shaft of the first motor 9 is fixedly connected to one end of the second double-headed screw 25.

[0045] As can be seen from the above, the second motor 13 drives the first lead screw 11 to rotate, causing the slider 12 to move along the first lead screw 11 to below the roll inside the protective film in the external processing equipment. Then, the hydraulic push rod 10 is activated to extend the telescopic end, causing the slide block 8 to drive the two V-shaped clamps 7 to move upwards and to the two sides of the protective film roll. Then, the first motor 9 is activated to drive the second double-headed screw 25 to rotate, causing the two V-shaped clamps 7 to move simultaneously to the center, clamping the protective film roll. The protective film roll is disconnected from the external processing equipment, and then the extension end is retracted by the hydraulic push rod 10, causing the slide 8 and the two V-shaped clamps 7 to move the protective film and the roll downward, so that the axis of the roll is aligned with the axis of the through hole 6. Then, the second motor 13 drives the first lead screw 11 to rotate, causing the slider 12 to move the hydraulic push rod 10, thereby moving the slide 8 and the two V-shaped clamps 7 to move the roll inside the protective film between one of the sets of through holes 6, thus completing the handling of the protective film without manual handling, improving the transfer efficiency.

[0046] Furthermore, to facilitate the movement of the base 1, it is preferable to provide a handle 2 fixed to the base 1 and multiple casters located at the bottom of the base 1. The casters include a bracket 15 rotatably connected to the base 1 and rollers 14 rotatably connected within the bracket 15. Based on this, by pushing the handle 2, the base 1 moves the bracket 15, while the rollers 14 roll on the ground, thereby reducing friction with the ground and facilitating transportation. The bracket 15 can rotate at the bottom of the base 1, facilitating the turning of the transfer vehicle during transportation.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
