Description

Technical Field

[0001] The utility model relates to the technical field of film cutting machines, in particular to a film film cutting machine. Background Art

[0002] Conductive cloth tape is a tape made of conductive cloth. Its characteristic is that the "glue" characteristic is added on the basis of conductive cloth. When producing conductive cloth tape, the produced tape roll needs to be slit into a set width. Usually a film cutter is used for slitting. The film roll is placed on the core shaft of the film cutter and cut by a cutting device.

[0003] The utility model with publication number CN212639349U discloses a coil cutting machine for convenient winding, which relates to the technical field of coil cutting machines, and specifically to a coil cutting machine for convenient winding, comprising a coil cutting machine winding column body, a sliding limit column fixedly connected to the surface of the coil cutting machine winding column body, and an installation inner cylinder movably sleeved on the surface of the coil cutting machine winding column body. The coil cutting machine for convenient winding, through the coordinated use of the sliding limit column, the sliding limit groove, the installation inner cylinder, and the installation outer cylinder, uses the sliding limit groove to sleeve the sliding limit column, so that the installation inner cylinder and the coil cutting machine winding column body are connected. The body rotates synchronously, thereby reducing the friction when the installation inner cylinder and the winding column body of the cutter and reel are sleeved together. Through the coordinated use of the support spring, the support plate, the anti-skid pad and the limit cylinder, the support spring is used to support the support plate, and then the support plate squeezes and fixes the reel, thereby preventing the reel from rotating freely on the installation outer cylinder. At the same time, the installation outer cylinder is installed by the fixing column, and the installation outer cylinder can be directly removed to sleeve the reel, and at the same time, the installation inner cylinder is sleeved on the surface of the winding column body of the cutter and reel to complete the winding operation, thereby improving the convenience of use of the cutter and reel that is convenient for winding.

[0004] The above existing solution has the following problems: the support plate is supported by a support spring, so that the support plate squeezes and fixes the reel, thereby preventing the reel from rotating freely on the installed outer cylinder. However, the elastic force of the spring is limited. Under the rotational torque of the outer cylinder and the lateral cutting torque of the cutting device, the reel may still rotate relative to the outer cylinder, thereby affecting the cutting of the reel.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides a technical solution: a film film cutting machine, including a film cutting machine body 1, a core shaft 2, a stabilizing frame 3 and a cutting device 4. A positioning disk 5 is provided on the outer wall fixing ring of one end of the core shaft 2 close to the film cutting machine body 1, and a slide groove 7 is provided on the positioning disk 5 and a plurality of slide blocks 6 for clamping the film roll are provided on the slide groove 7 and correspond to the slide groove 7 one by one. A swivel groove 19 is provided on the core shaft 2 on one side of the positioning disk 5 close to the film cutting machine body 1, and a swivel 9 is rotatably provided in the swivel groove 19. A control disk 10 is provided on the outer wall fixing ring of the swivel 9, and a plurality of control grooves 11 corresponding to the slide groove 7 are evenly provided on the control disk 10 around the center of the control disk 10. A sliding shaft 8 is slidably provided in the control groove 11, which passes through the slide groove 7 and is fixedly connected to the clamping block 6, and a rotating mechanism for controlling the rotation of the swivel 9 is provided on the core shaft 1.

[0021] Specifically, the control groove 11 is an arc-shaped groove and the groove width is consistent with the groove width of the slide groove 7. The inner walls of the control groove 11 and the slide groove 7 are both in contact with the inner wall of the sliding shaft 8, ensuring the stability of the sliding of the sliding shaft 8 in the control groove 11 and the slide groove 7, thereby ensuring the stable clamping of the clamping block 6. By rotating the control disk 10, the inner wall of the control groove 11 exerts force on the sliding shaft 8 to make the sliding shaft 8 slide in the slide groove 7, thereby controlling the clamping block 6 to move toward or away from the center of the positioning disk 5 at the same time, thereby achieving the clamping of the film.

[0022] Specifically, the clamping block 6 is fitted with the positioning plate 5, the width of the clamping block 6 is greater than the width of the slide groove 7, and the end of the sliding shaft 8 located outside the control plate 10 is fixed with a support plate 12 that abuts against the end face of the control plate 10. The low plate 12 fits with the end face of the control plate 10, and the clamping block 6 fits with the end face of the positioning plate 5, thereby ensuring the sliding stability of the clamping block 6.

[0023] Specifically, the rotating mechanism includes a driven gear 13, a motor 15 and a driving gear 16. A fixed seat 14 is fixedly provided on the core shaft 2. The motor 15 is fixedly provided in the fixed seat 14 and the output end is fixedly connected to the driving gear 16. The driven gear 13 is fixedly sleeved on the outer wall of the rotating ring 9 and meshes with the driving gear 16. The motor 15 controls the driving gear 16 to rotate, and the driven gear 13 is driven to rotate through the meshing of the driving gear 16 and the driven gear 3. The rotation of the driven gear 13 drives the rotating ring 9 to rotate, thereby driving the control disk 10 to rotate, and controlling the clamping block 6 to clamp and release the film.

[0024] Specifically, the mandrel 2 is provided with a clearance groove 17 and multiple clearance grooves 17 are evenly provided along the axial direction of the mandrel 2. When the cutting device 4 cuts the film, the clearance grooves 17 can prevent the blade from accidentally cutting the mandrel 2 and ensure that the film is completely cut.

[0025] Specifically, a chip collecting frame 18 is provided on the table of the cutting device 4 below the cutting blade. The chip collecting frame 18 can collect waste chips generated by the blade during the cutting process. A magnetic strip is provided at the bottom of the chip collecting frame 18 to improve the stability of the chip collecting frame 18.

[0026] A specific application example of this embodiment is:

[0027] When the device is in use, the stabilizing frame 3 is removed, the film is slid from the core shaft 2, and then the stabilizing frame 3 is shifted to position the core shaft 2 (this is the prior art), and the film is moved to abut against the positioning disk 5, and the motor is started through the film cutting machine body 1. The motor 15 controls the driving gear 16 to rotate, and the driven gear 13 is driven to rotate through the meshing of the driving gear 16 and the driven gear 13. The rotation of the driven gear 13 drives the rotating ring 9 to rotate, thereby driving the control disk 10 to rotate, and the inner wall of the control groove 11 exerts force on the sliding shaft 8 to make the sliding shaft 8 slide in the sliding groove 7, thereby controlling the clamping block 6 to move toward the center of the positioning disk 5 at the same time, so as to clamp the film, and the film cutting machine body 1 controls the core shaft 2 to rotate and drive the film to rotate, and starts the cutting device for cutting (this is the prior art). When the cutting device 4 cuts the film, the clearance groove 17 can prevent the blade from accidentally cutting the core shaft 2, and can also ensure that the film is completely cut, and the chip collecting frame 18 can collect the waste chips generated by the blade during the cutting process.
