Technical Field

[0001] This utility model belongs to the field of plastic film production technology, and more specifically, it relates to a plastic film slitting machine. Background Technology

[0002] A plastic film slitting machine is a specialized piece of equipment used to cut wide plastic films (such as PE, PP, PVC, BOPP, etc.) into specified widths or lengths as required.

[0003] During the use of a slitting machine, the slitting mechanism needs to be maintained and disassembled to ensure its normal operation. However, the maintenance and disassembly of commonly used slitting machines require operators to have certain professional knowledge to complete the maintenance and repair, making the maintenance operation relatively inconvenient and unable to be carried out quickly and efficiently. Utility Model Content

[0004] This disclosure relates to a plastic film slitting machine to solve the problem mentioned in the background art that the maintenance and disassembly of commonly used slitting machines requires operators to have certain professional knowledge to complete the maintenance and repair, thus the maintenance operation is relatively unchanging and cannot be carried out quickly and efficiently.

[0005] This utility model discloses a plastic film slitting machine, which is achieved by the following specific technical means: This utility model provides a plastic film slitting machine, including: a machine frame, with a slitting frame fixedly installed in the middle of the machine frame; the machine frame also includes: two film rollers, which rotate symmetrically at the bottom of both ends of the machine frame; two drive motors, which are symmetrically fixedly installed at both ends of the machine frame; the shaft of the drive motor is connected to one end of the film roller.

[0006] As a preferred embodiment of this utility model, the machine support also includes: a mounting bracket, which is integrally disposed in the middle of the machine support; the mounting bracket is fixedly connected to the slitting frame; and two limiting rollers, which rotate symmetrically at the bottom of the mounting bracket.

[0007] As a preferred embodiment of this utility model, the slitting frame further includes: an adjusting cylinder, wherein the number of adjusting cylinders is set to two, and the adjusting cylinders are symmetrically fixedly installed at both ends of the slitting frame; and an adjusting seat, which is fixedly installed at the bottom of the piston rod of the adjusting cylinder.

[0008] As a preferred embodiment of this utility model, the slitting frame further includes: a mounting slot, which is T-shaped and located on one side of the adjusting seat; and a fixing slot located on the upper inner side of the adjusting seat.

[0009] As a preferred embodiment of this utility model, the slitting frame further includes: an adjusting support base, which is engaged and installed between adjusting seats; the two sides of the adjusting support base are symmetrically and integrally arranged on the T-shaped block, and the T-shaped block of the adjusting support base engages with the mounting slot; and two limiting slots, which are symmetrically opened on both sides of the adjusting support base.

[0010] As a preferred embodiment of this utility model, the slitting frame further includes: an adjusting slitting seat, the number of which is set to four, and the adjusting slitting seat slides outside the adjusting support seat; an adjusting screw, the adjusting screw rotates on the top of the adjusting slitting seat; a slitting blade, the slitting blade is fixedly installed at the bottom of the adjusting slitting seat; a fixing shell, the number of which is set to two, the fixing shells are symmetrically fixedly installed at the top of both ends of the adjusting support seat; and a fixing block, the fixing block slides inside the fixing shell, and a spring is installed between the fixing shell and the fixing block.

[0011] Compared with the prior art, the present invention has the following beneficial effects: When the slitting mechanism of the slitting machine needs maintenance or blade replacement after a certain period of operation, the operator can lift the top of the fixed block to smoothly remove one end of the fixed block from the fixed slot. At this time, the locking state of the adjusting support is released, and it can be easily slid outward along the guide rail. Subsequently, technicians can perform wear detection, edge sharpening, or complete replacement of the slitting blade on the adjusting support to ensure its cutting accuracy and durability.

[0012] After the blade maintenance is completed, simply push the adjustment support back to its original position. The fixing block will automatically reset under the action of the spring and accurately snap into the fixing slot for quick locking. This modular quick-release structure design greatly simplifies the maintenance process of traditional slitting machines. Blade replacement can be completed without additional tools, effectively reducing downtime and improving production efficiency. Attached Figure Description

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0020] Example: As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a plastic film slitting machine, including: a machine frame 1, with a slitting frame 2 fixedly installed in the middle of the machine frame 1; the machine frame 1 also includes: two film rollers 101, which rotate symmetrically at the bottom of both ends of the machine frame 1; two drive motors 102, which are symmetrically fixedly installed at both ends of the machine frame 1; the shaft of the drive motor 102 is connected to one end of the film roller 101; a mounting bracket 103, which is integrally disposed in the middle of the machine frame 1; the mounting bracket 103 is fixedly connected to the slitting frame 2; and two limiting rollers 104, which rotate symmetrically at the bottom of the mounting bracket 103.

[0021] The slitting frame 2 further includes: two adjusting cylinders 201, which are symmetrically fixed at both ends of the slitting frame 2; an adjusting seat 202, which is fixedly installed at the bottom of the piston rod of the adjusting cylinder 201; a mounting slot 203, which is T-shaped and located on one side of the adjusting seat 202; a fixing slot 204, located on the upper inner side of the adjusting seat 202; an adjusting support 205, which is engaged between the adjusting seats 202; the adjusting support 205 is symmetrically and integrally set on the T-shaped blocks on both sides, and the T-shaped blocks of the adjusting support 205 engage with the mounting slot 203; and a limiting groove 2. 06. Two limiting grooves 206 are provided, and the limiting grooves 206 are symmetrically opened on both sides of the adjusting support 205; four adjusting slitting seats 207 are provided, and the adjusting slitting seats 207 slide outside the adjusting support 205; adjusting screw 208 is rotated on the top of the adjusting slitting seat 207; slitting blade 209 is fixedly installed on the bottom of the adjusting slitting seat 207; two fixing shells 210 are provided, and the fixing shells 210 are symmetrically fixedly installed on the top of both ends of the adjusting support 205; and a fixing block 211 slides inside the fixing shell 210, and a spring is installed between the fixing shell 210 and the fixing block 211.

[0022] The specific usage and function of this embodiment are as follows: During the use of the plastic film slitting machine, the position of the slitting seat 207 is changed by manually adjusting it. After the slitting seat 207 is adjusted to the required position, the adjusting screw 208 is rotated, and the bottom of the adjusting screw 208 contacts the adjusting support seat 205 for fixation.
