Description

Technical Field

[0001] This utility model relates to the field of film slitting technology, and in particular to a film slitting device. Background Technology

[0002] After processing, the film needs to be cut using a film slitting device.

[0003] A search revealed a patent document with publication number "CN220113394U" that discloses a continuous film slitting device, comprising: a slitting machine, a cutting assembly, and a support assembly. The slitting machine includes a machine body, a drive roller, and a driven roller, with the drive roller and driven roller arranged parallel to each other on the machine body. The cutting assembly is mounted on the drive roller and includes a cutting connecting tube and a cutting blade. The cutting connecting tube is sleeved on the outer wall of the drive roller, and the cutting blade is mounted on the outer wall of the cutting connecting tube. The support assembly is mounted on the driven roller and includes a support connecting tube, a cutting table, and a cutting groove. The support connecting tube is sleeved on the outside of the driven roller, and the annular cutting table is mounted on the outer wall of the support connecting tube. The cutting assembly can slide on the drive roller, and the support assembly can slide on the driven roller to change the spacing between the cutting blades and adjust the width of the film cut, adapting to the cutting of films with different width requirements.

[0004] Based on the above search and combined with existing technology, it was found that the existing film slitting device requires the cutting blade (or cutting table) to be tightened and fixed by bolts after it is moved. However, during adjustment, the positions of multiple cutting blades often need to be adjusted at the same time, and multiple bolts need to be tightened repeatedly, which makes the adjustment process cumbersome. Therefore, a film slitting device is needed. Utility Model Content

[0007] Both the cutting blade and the cutting table are slidably connected to the rotating roller via a connecting sleeve, which slides along the axial direction of the rotating roller.

[0008] The rotating roller is equipped with a limiting strip for axially limiting the connecting sleeve, and the limiting strip abuts against the inner side of the connecting sleeve;

[0009] The connecting sleeve is also equipped with an actuating component. When an external force is applied to the actuating component, it pushes the limiting strip away from the connecting sleeve, allowing the connecting sleeve to slide along the axial direction of the rotating roller.

[0019] A slider is fixed inside the connecting sleeve, and the slider is slidably embedded in the groove.

[0020] In summary, the technical effects and advantages of this utility model are as follows:

[0021] 1. In this utility model, by improving the structure of the rotating roller and the connecting sleeve, and adding a limiting strip and a triggering component, the contact limit or limit of the connecting sleeve can be achieved simply by applying force and releasing it, which simplifies the operation of adjusting the position of the connecting sleeve, makes it convenient to use, and improves the efficiency of adjusting the cutting blade and the cutting table.

[0022] 2. In this utility model, by setting the ball and the groove, when the abutment bar abuts against the limiting strip, the ball rolls and is embedded in the groove, so that the end of the abutment bar and the limiting strip make rolling contact, which makes it easier to move the abutment bar, and can also reduce the wear of both and extend the service life of the abutment bar and the limiting strip.

[0023] In addition, by setting up the expansion plate, it is easier for workers to apply inward pressure to the abutment, the direction of force application is more flexible, and the expansion plate exerts less pressure on the workers' hands compared to the abutment, thus providing workers with a better user experience.

[0031] 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.

[0032] Example: Reference Figures 1-5The film slitting device shown includes a machine body 1, two rotating rollers 2 arranged vertically and horizontally, a set of cutting blades 3 respectively mounted on the two rotating rollers 2 and cooperating with each other, and a set of cutting tables 4;

[0033] Both the cutting blade 3 and the cutting table 4 are slidably connected to the rotating roller 2 through the connecting sleeve 5. The connecting sleeve 5 slides along the axial direction of the rotating roller 2. Specifically, a groove 24 is also provided on the circumference of the rotating roller 2. The groove 24 also extends along the axial direction of the rotating roller 2. A slider 8 is fixed inside the connecting sleeve 5. The slider 8 is slidably embedded in the groove 24.

[0034] A limiting strip 6 for axially limiting the connecting sleeve 5 is installed inside the rotating roller 2. The limiting strip 6 abuts against the inner side of the connecting sleeve 5.

[0035] The connecting sleeve 5 is also equipped with an actuating component 7. When an external force is applied to the actuating component 7, it pushes the limiting strip 6 away from the connecting sleeve 5, so that the connecting sleeve 5 can slide along the axial direction of the rotating roller 2.

[0036] Based on the above structure, under normal conditions, when no external force (pressure) is applied to the actuating component 7, the limiting strip 6 axially limits the connecting sleeve 5. Since the connecting sleeve 5 is axially slidably connected to the rotating roller 2, when the connecting sleeve 5 is axially limited, it is relatively fixed to the rotating roller 2, thereby enabling the rotating roller 2 to drive the connecting sleeve 5 to rotate, which in turn drives the cutting blade 3 and the cutting table 4 to rotate, completing the cutting operation of the film. When an external force is applied to the actuating component 7, the limiting strip 6 is pushed away from the connecting sleeve 5, thereby releasing the limiting effect of the limiting strip 6 on the connecting sleeve 5, allowing the connecting sleeve 5 to slide along the axial direction of the rotating roller 2. At this time, the position of the connecting sleeve 5 can be adjusted, thereby adjusting the position of the cutting blade 3 and the cutting table 4. By simply applying and releasing force, the contact limit or limit of the connecting sleeve 5 can be achieved, simplifying the operation of adjusting the position of the connecting sleeve 5, making it convenient to use, and improving the efficiency of adjusting the cutting blade 3 and the cutting table 4.

[0037] Furthermore, the rotating roller 2 is a hollow tube shaft. Multiple elongated holes are evenly opened on the periphery of the rotating roller 2. A central column 21 is fixed in the middle of the rotating roller 2. The central column 21 is fixed to the inner wall of the rotating roller 2 by a support rod 22. A first spring 23 is also fixed on the central column 21. The other end of the first spring 23 is fixed to the inner side of the limiting strip 6.

[0038] The limiting strip 6 is slidably embedded in the elongated hole of the rotating roller 2. The side wall of the limiting strip 6 that is in contact with the connecting sleeve 5 is provided with multiple limiting grooves 61 that are evenly distributed at equal intervals along the length of the limiting strip 6.

[0039] The inner side of the connecting sleeve 5 is integrally formed with a limiting rib 51, and the limiting rib 51 is provided with multiple ribs and is engaged with multiple limiting grooves 61.

[0040] The first spring 23 applies an outward elastic force to the limiting strip 6, causing the limiting strip 6 to press against the inner side of the connecting sleeve 5, thereby causing the limiting rib 51 to engage in the limiting groove 61, thus achieving axial limiting of the connecting sleeve 5.

[0041] Furthermore, the connecting sleeve 5 is also provided with a through hole 52, which corresponds to the position of the limiting strip 6. The trigger component 7 is installed on the through hole 52. Specifically:

[0042] An installation groove 521 is provided on the inner wall of the socket 52;

[0043] The actuation component 7 includes a stop rod 71, a wing plate 73, and a second spring 74. The stop rod 71 is movably inserted into the insertion hole 52. The wing plate 73 is integrally formed with the periphery of the stop rod 71. The wing plate 73 is slidably embedded in the mounting groove 521. The wing plate 73 is elastically connected to the inner wall of the mounting groove 521 through the second spring 74.

[0044] When the position of the connecting sleeve 5 needs to be adjusted, the user only needs to press the abutment rod 71, which causes the abutment rod 71 to drive the wing plate 73 to move. At this time, the wing plate 73 overcomes the elastic force of the second spring 74 and slides in the mounting groove 521, so that the inner end of the abutment rod 71 abuts against the limiting strip 6 and pushes the limiting strip 6 away from the inner side of the rotating roller 2 away from the connecting sleeve 5, thereby releasing the limiting effect of the limiting strip 6 on the connecting sleeve 5. At this time, the operator only needs to slide the connecting sleeve 5 left and right to adjust the connecting sleeve 5. After the adjustment is completed, the abutment rod 71 is released, and the abutment rod 71 can move outward and away from the limiting strip 6 under the elastic force of the second spring 74. The limiting strip 6 is reset under the elastic force of the first spring 23 and abuts against the connecting sleeve 5 again. The limiting rib 51 and the limiting groove 61 cooperate to achieve the axial limiting effect of the connecting sleeve 5.

[0045] Furthermore, a ball bearing 72 is rolled and embedded at one end of the abutment 71 near the limiting strip 6, and an expansion plate 75 is fixed at the other end of the abutment 71 away from the limiting strip 6 on the outside of the connecting sleeve 5. The expansion plate 75 is an arc-shaped plate that matches the curvature of the outside of the connecting sleeve 5.

[0046] The limiting strip 6 has a groove 62 on the outer side of the connecting sleeve 5, which allows the ball 72 to roll and embed.

[0047] By setting the ball bearing 72 and the groove 62, when the abutment rod 71 abuts against the limiting strip 6, the ball bearing 72 rolls and is embedded in the groove 62, so that the end of the abutment rod 71 makes rolling contact with the limiting strip 6, which makes it easier to move the abutment rod 71 (the abutment rod 71 moves with the connecting sleeve 5), and can also reduce the wear of both and extend the service life of the abutment rod 71 and the limiting strip 6.

[0048] In addition, by setting the expansion plate 75, it is easier for the staff to apply inward pressure to the abutment 71, the direction of force application is more flexible, and the expansion plate 75 exerts less pressure on the staff's hands compared to the abutment 71, thus providing the staff with a better user experience.

[0049] The working principle of this utility model is as follows: In daily use, under normal conditions, when the abutment 71 is not subjected to external force, the abutment 71 moves away from the limiting strip 6 under the elastic force of the second spring 74, causing the ball 72 to separate from the limiting strip 6. The limiting strip 6 then presses against the inner side of the connecting sleeve 5 under the elastic force of the first spring 23, causing the limiting rib 51 to engage in the limiting groove 61, thus axially limiting the connecting sleeve 5. Since the connecting sleeve 5 is axially slidably connected to the rotating roller 2, when the connecting sleeve 5 is axially limited, it is relatively fixed to the rotating roller 2, thereby enabling the rotating roller 2 to drive the connecting sleeve 5 to rotate, which in turn drives the cutting blade 3 and the cutting table 4 to rotate, completing the cutting operation of the film.

[0050] When the operator applies pressure to the push rod 71 through the expansion plate 75, the push rod 71 moves into the connecting sleeve 5, causing the ball 72 to roll and abut against the groove 62 of the limiting strip 6, pushing the limiting strip 6 away from the connecting sleeve 5, thereby releasing the limiting effect of the limiting strip 6 on the connecting sleeve 5, allowing the connecting sleeve 5 to slide along the axial direction of the rotating roller 2. At this time, the operator only needs to move the connecting sleeve 5 left and right to complete the adjustment, thereby achieving the purpose of adjusting the position of the cutting blade 3 and the cutting table 4.

[0051] After adjustment, simply loosen the expansion plate 75, and the abutment rod 71 will move outward and away from the limiting strip 6 under the elastic force of the second spring 74. The limiting strip 6 will then reset under the elastic force of the first spring 23 and abut against the connecting sleeve 5 again. The limiting rib 51 and the limiting groove 61 will cooperate to achieve the axial limiting effect on the connecting sleeve 5.

[0052] It should be further noted that the technical features of the body 1, the cutting blade 3, and the cutting table 4 involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
