[0001] The present application relates to the field of laminating machines, and in particular to a film roll cutting device for a laminating machine. Background Art
[0002] With the rapid development of the printing and packaging industry, the need to improve production efficiency and reduce production costs is becoming increasingly urgent. Although most laminating machines on the market can meet basic laminating functions, they still require manual adjustment of the film roll width when laminating paper of different sizes.

Although this method can achieve precise adjustment, due to the high cost of film rolls, frequent replacement undoubtedly increases the company's operational burden; the second is to use handheld tools with cutting functions to perform temporary trimming on site. Although this method can flexibly respond to emergencies, it is obviously not efficient and stable enough for continuous production lines.

[0029] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0030] The following is combined with Figure 1-2 This application is described in further detail.
[0031] The present application discloses a film roll cutting device for a laminating machine, such as Figure 1 As shown, the machine comprises a frame 1, on which a mounting roller 11 is fixedly mounted, and a film roll is sleeved on the mounting roller 11. A fixed shaft 2 is fixedly connected to the frame 1, and the length direction of the fixed shaft 2 is consistent with the length direction of the mounting roller 11. A cutting blade 3 is relatively rotatable on the fixed shaft 2, and a control component 4 for controlling the fixing of the cutting blade 3 is provided on the fixed shaft 2.
[0032] like Figure 1 and 2 As shown, the control assembly 4 includes a sliding block 41, a support arm 42, and a first bolt 43. The sliding block 41 slides on the fixed shaft 2 and is slidably connected to the fixed shaft 2. The sliding block 41 is provided with a second bolt 411, which is a seven-shaped handle bolt. The second bolt 411 is threadedly connected to the sliding block 41, passes through the sliding block 41, and abuts the fixed shaft 2. The support arm 42 is rotatably connected to the sliding block 41, and the cutting knife 3 is mounted on the support arm 42. The first bolt 43 is threadedly connected to the sliding block 41, passes through the sliding block 41, and abuts the support arm 42. The operator can move the sliding block 41 according to the size of the film roll. The movement of the sliding block 41 can drive the movement of the cutting blade 3. When the sliding block 41 moves to the appropriate position, the operator can screw in the second bolt 411, so that the second bolt 411 passes through the sliding block 41 and abuts the fixed shaft 2. The second bolt 411 can limit the sliding block 41, thereby achieving the fixation of the cutting blade 3 in the length direction of the fixed shaft 2. When the cutting blade 3 needs to be used, the operator can rotate the support arm 42, thereby driving the rotation of the cutting blade 3. When the cutting blade 3 abuts the film roll, the operator screws in the first bolt 43, so that the first bolt 43 passes through the sliding block 41 and abuts the support arm 42. The first bolt 43 can limit the support arm 42, thereby limiting the position of the cutting blade 3, facilitating the cutting of the film roll.
[0033] like Figure 2As shown, a sliding plate 5 is slidably connected to the support arm 42. The cutting blade 3 and the sliding plate 5 are detachably connected. The sliding plate 5 and the support arm 42 are in contact with each other. A third bolt 51 is threadedly connected to the sliding plate 5. The support arm 42 has a waist-shaped hole 421, and the third bolt 51 slides within the waist-shaped hole 421. The operator moves the sliding plate 5 according to the size of the film roll. The movement of the sliding plate 5 drives the movement of the cutting blade 3, allowing the cutting blade 3 to rotate and abut against the film roll. When the sliding plate 5 moves to the appropriate position, the operator screws in the third bolt 51, so that the third bolt 51 passes through the waist-shaped hole 421 and is threadedly connected to the sliding plate 5. The third bolt 51 abuts the opening of the waist-shaped hole 421. The third bolt 51 can limit the sliding plate 5, so that the sliding plate 5 is fixed on the support arm 42, thereby fixing the cutting blade 3 and facilitating the cutting of the film roll.
[0034] like Figure 2 As shown, a mounting housing 6 is detachably connected to the sliding plate 5, and the cutting blade 3 is mounted within the mounting housing 6. A fourth bolt 61 is provided on the mounting housing 6, which passes through the sliding plate 5 and is threadedly connected to the mounting housing 6. The mounting housing 6 provides a mounting position for the cutting blade 3 and also protects the cutting blade 3. When the mounting housing 6 is to be installed, the operator moves the mounting housing 6 to align it with the sliding plate 5 and then screws in the fourth bolt 61. The fourth bolt 61 limits the mounting housing 6, securing it to the sliding plate 5 and facilitating installation of the cutting blade 3.
[0035] like Figure 2 As shown, the cutting knife 3 is provided with a fifth bolt 31, which passes through the cutting knife 3 and is threadedly connected to the mounting shell 6; when the cutting knife 3 needs to be installed, the operator moves the cutting knife 3 to a suitable position of the mounting shell 6, and then screws in the fifth bolt 31. The fifth bolt 31 can limit the cutting knife 3, thereby realizing the installation of the cutting knife 3 and facilitating the cutting work of the cutting knife 3.
[0036] like Figure 2 As shown, a protective cover 62 is provided on the mounting shell 6. When the cutting knife 3 is not needed, the operator can cover the protective cover 62 on the mounting shell 6. The protective cover 62 can protect the cutting knife 3 and reduce the possibility of damage to the cutting knife 3.
[0037] like Figure 2 As shown, an auxiliary rod 12 is fixedly connected to the frame 1. The auxiliary rod 12 is provided with a scale. The length direction of the auxiliary rod 12 is consistent with the length direction of the fixed shaft 2. The auxiliary rod 12 is located below the fixed shaft 2. The operator can move the sliding block 41 according to the scale on the auxiliary rod 12, so that the sliding block 41 can move the cutting knife 3 to the appropriate position.
[0038] The implementation principle of the film roll cutting device for a laminating machine in the embodiment of the present application is as follows:
[0039] The operator moves the sliding block 41 according to the size of the film roll and the scale on the auxiliary rod 12, thereby driving the movement of the cutting knife 3, and then screws in the second bolt 411 to limit the sliding block 41; then the operator rotates the support arm 42 so that the support arm 42 drives the cutting knife 3 to contact the film roll, and screws in the first bolt 43 to fix the support arm 42 and the cutting knife 3, thereby facilitating the cutting of the film roll.
[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
