Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a packaging film cutting mechanism. Background Technology

[0002] In existing packaging film packaging equipment, the slitting mechanism typically includes a cutting device and a slitting roller. During the slitting process, the slitting roller rotates as the packaging film is transported forward, while the cutting device presses the packaging film against the slitting roller to cut the film. However, existing cutting devices are prone to wear, especially when the cutting device is a circular cutter. The circular cutter rotates in opposite directions from the slitting roller, causing the circular cutter to wear easily, reducing its service life, and affecting production costs. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a packaging film slitting mechanism that can reduce wear on the cutting device and improve its service life.

[0005] The packaging film slitting mechanism according to the embodiments of the present invention has at least the following beneficial effects: In the packaging film slitting mechanism provided by the present invention, during the slitting process, the cutting device can press against the support member. As the packaging film passes between the support member and the cutting device, the cutting device can cut the packaging film. In particular, when the slitting roller rotates, since the support member is rotatably mounted on the slitting roller and the rotation axis of the support member is along the axial direction of the slitting roller, the sliding friction between the support member and the cutting device is smaller, thereby reducing the wear of the cutting device and improving its service life.

[0006] According to some embodiments of the present invention, the slitting roller has at least one annular mounting groove around its axis, the support member is annular, and all the support members are rotatably mounted in all the mounting grooves in a one-to-one correspondence, wherein the support member is flush with the groove wall of the mounting groove.

The lead screw is rotatably mounted on the frame. One end of the lead screw is screwed to one end of the crossbeam. The other end of the lead screw is provided with an operating part or is connected to a driving device. The cutting device is mounted on the crossbeam.

[0012] According to some embodiments of the present invention, multiple cutting devices are provided and installed at intervals on the crossbeam, and a positioning plate is provided between two adjacent cutting devices, the interval between two adjacent cutting devices being determined by the positioning plate.

[0013] According to some embodiments of the present invention, the mounting shaft is detachably mounted with two limiting members, and all the rollers are located between the two limiting members. The two limiting members are used to cooperate with each other to restrict the rollers from sliding along the mounting shaft.

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] Reference Figure 1 and Figure 2 According to an embodiment of the present invention, a packaging film slitting mechanism includes a frame 100, at least one cutting device 200, and a slitting roller 300. The cutting device 200 is mounted on the frame 100, and the slitting roller 300 is mounted on the frame 100. The slitting roller 300 is located on one side of the cutting device 200. At least one support member 410 is rotatably mounted on the slitting roller 300 at a position corresponding to the cutting device 200. The rotation axis of the support member 410 is along the axial direction of the slitting roller 300. The support member 410 is used to cooperate with the corresponding cutting device 200 to cut the packaging film.

[0028] The packaging film slitting mechanism provided by this utility model allows the cutting device 200 to press against the support member 410 during the slitting process. As the packaging film passes between the support member 410 and the cutting device 200, the cutting device 200 can cut the packaging film. When the slitting roller 300 rotates, since the support member 410 is rotatably mounted on the slitting roller 300 and the rotation axis of the support member 410 is along the axial direction of the slitting roller 300, the support member 410 will not rotate synchronously with the slitting roller 300. This reduces the sliding friction between the support member 410 and the cutting device 200, thereby reducing the wear of the cutting device 200 and improving its service life.

[0029] Reference Figure 1 and Figure 2According to some embodiments of this utility model, the slitting roller 300 has at least one annular mounting groove 310 around its axis, and the support member 410 is annular. All the support members 410 are rotatably mounted in all the mounting grooves 310 in a one-to-one correspondence, wherein the support member 410 is flush with the groove wall of the mounting groove 310. With the above arrangement, only one support member 410 needs to be installed in each mounting groove 310, which is simple in structure, convenient to implement, and helps to control the cost of the entire packaging film slitting mechanism. In particular, since the cutting device 200 and the support member 410 are in a pressing fit, the support member 410 will not rotate with the slitting roller 300, thereby reducing the relative sliding distance between the support member 410 and the cutting device 200 at the contact position, or even preventing the support member 410 and the cutting device 200 from sliding relative to each other, so that the sliding friction between the support member 410 and the cutting device 200 is small.

[0030] Reference Figure 1 and Figure 3 According to some embodiments of this utility model, the cutting device 200 is configured as a circular cutter. Since the blade of the circular cutter can rotate against the direction of movement of the packaging film, the cutting efficiency is higher, and the position of the circular cutter cutting the packaging film constantly changes, thus extending the overall service life of the cutting device 200. It can be imagined that the blade of the circular cutter rotates at a certain speed when cutting the packaging film, and the static friction between the circular cutter and the support member 410 can drive the support member 410 to rotate synchronously with the blade of the circular cutter. Therefore, the relative sliding between the support member 410 and the cutting device 200 at their contact points is small or even nonexistent, resulting in minimal sliding friction between them.

[0031] In practice, the circular cutter can be either pneumatically driven or electrically driven.

[0032] It should be noted that in some other embodiments, the cutting device 200 described above can also be configured as a fixed cutting device. In this case, the support member 410 can rotate relative to the slitting roller 300, while the support member 410 is stationary relative to the cutting device 200. The sliding friction between the support member 410 and the cutting device 200 is small, thereby reducing the wear of the cutting device 200.

[0033] Reference Figure 1 and Figure 2 According to some embodiments of this utility model, a bearing 400 is installed in the mounting groove 310, and the support member 410 is the outer ring of the bearing 400. With the above arrangement, the support member 410 can rotate more flexibly and smoothly relative to the slitting roller 300. In addition, it can also make the entire mechanism simple and easy to install.

[0034] Reference Figure 1 and Figure 2According to some embodiments of this utility model, the slitting roller 300 includes a mounting shaft 800 and at least two rollers 300a. The mounting shaft 800 is mounted on the frame 100, and the rollers 300a are sleeved on the mounting shaft 800. The mounting groove 310 is formed by two adjacent rollers 300a and the mounting shaft 800. The rollers 300a can rotate relative to the mounting shaft 800, or the rollers 300a are fixedly mounted on the mounting shaft 800, and the mounting shaft 800 can rotate relative to the frame 100. This configuration facilitates the installation of the bearing 400.

[0035] It is conceivable that the aforementioned support member 410 can also be arranged in a similar manner. For example, multiple support members 410 are arranged around the outer periphery of the slitting roller 300 at the corresponding position of the cutting device 200. Each support member 410 can rotate relative to the slitting roller 300. Thus, the friction between the cutting device 200 and each support member 410 at the corresponding position is mainly rolling friction. The overall friction between the support member 410 and the cutting device 200 is smaller than the sliding friction between the slitting roller 300 and the cutting device 200 in the prior art.

[0036] Reference Figure 1 and Figure 3 According to some embodiments of the present invention, an adjustment device 500 is provided on the frame 100, and a cutting device 200 is installed on the adjustment device 500. The adjustment device 500 can adjust the position of the cutting device 200 along the axial direction of the slitting roller 300, so that the cutting position of the cutting device 200 can be adjusted according to actual needs so that the size of the slitting packaging film meets the production requirements.

[0037] Reference Figure 1 and Figure 3 According to some embodiments of this utility model, the adjusting device 500 includes a crossbeam 510 and a lead screw 520. The crossbeam 510 is mounted on the frame 100 and can slide along the axial direction of the slitting roller 300. The length of the crossbeam 510 is set along the axial direction of the slitting roller 300. The lead screw 520 is rotatably mounted on the frame 100. One end of the lead screw 520 is screwed to one end of the crossbeam 510, and the other end of the lead screw 520 is provided with an operating part 521 or is connected to a driving device. The cutting device 200 is mounted on the crossbeam 510. With the above configuration, the adjusting device 500 has a simple structure, is easy to install, and can accurately adjust the position of the cutting device 200, making adjustment convenient and simple.

[0038] Reference Figure 1 and Figure 3According to some embodiments of the present invention, multiple cutting devices 200 are provided and installed at intervals on the crossbeam 510. A positioning plate 220 is provided between two adjacent cutting devices 200. The interval between two adjacent cutting devices 200 can be determined by the positioning plate 220. With the above arrangement, each cutting device 200 can be installed on the crossbeam 510 more quickly and accurately.

[0039] Reference Figure 3 and Figure 4 In the specific implementation process, two adjacent cutting devices 200 are connected and fixed by a positioning plate 220. A suspension plate 221 is inclinedly provided at one end of the positioning plate 220, and a hook 210 is provided at the end of the cutting device 200 facing away from the suspension plate. Grooves 511 are provided on opposite sides of the crossbeam 510. The cutting device 200 and the positioning plate 220 can be slidably installed onto the crossbeam 510 as a whole by slidingly engaging the suspension plate 221 with one groove 511 and the hook 210 with the other groove 511. Then, the cutting device 200 is fixed by abutting the side wall of the corresponding groove 511 with the suspension plate 221 and engaging the hook 210 with the side wall of the corresponding groove 511. With this configuration, the cutting device 200 is easy to assemble and disassemble, facilitating replacement.

[0040] It is conceivable that the aforementioned adjustment device 500 can also be configured in other ways. For example, the adjustment device 500 can be a linear motor or a cylinder, replacing the aforementioned lead screw 520.

[0041] Reference Figure 2 According to some embodiments of the present invention, the mounting shaft 800 is detachably mounted with two limiting members 810, and all the rollers 300a are located between the two limiting members 810. The two limiting members 810 are used to cooperate with each other to restrict the rollers 300a from sliding along the mounting shaft 800, thereby fixing the position of each roller 300a.

[0042] Reference Figure 1According to some embodiments of this utility model, a color mark detection device 600 is installed on the frame 100. The color mark detection device 600 is located on one side of the slitting roller 300. A first guide roller 710 is arranged between the slitting roller 300 and the color mark detection device 600. A second guide roller 720 is arranged on the side of the slitting roller 300 away from the color mark detection device 600. The packaging film output from the color mark detection device 600 passes sequentially through the first guide roller 710, the slitting roller 300, and the second guide roller 720. Thus, the color mark on the packaging film can be detected by the color mark detection device 600 to obtain the slitting position of the packaging film. Then, the packaging film is sequentially conveyed from the color mark detection device 600 through the first guide roller 710, the slitting roller 300, and the second guide roller 720. The color mark detection device 600 is a commonly used device in this technical field, and its specific structure will not be described in detail here.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
