Description

Technical Field

[0001] This utility model relates to the field of heat shrink film production technology, specifically a POF heat shrink film cutting device. Background Technology

[0002] In the production process of POF heat shrink film, the rolled heat shrink film, due to its large width, generally cannot be directly packaged and needs to be cut into smaller rolls. Traditionally, this involves using a POF heat shrink film splitting machine to cut the rolls after winding.

[0003] As indicated by announcement number CN205367262U, a POF heat shrink film slicing device is described. This device includes a fixed rod, a POF heat shrink film slicing blade, fastening bolts, and fixed ends. The POF heat shrink film slicing blade is fixed to the fixed rod by the fastening bolts. A fixed end is welded to each end of the fixed rod. The device slices the POF heat shrink film during the winding process and can accommodate multiple POF heat shrink film slicing blades.

[0004] When the above-mentioned device is in use, the cutting blade is designed to be inclined, but there is no limiting mechanism, which makes the cutting blade easy to lift up during cutting and there is a certain degree of looseness; therefore, we propose a POF heat shrink film cutting device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a POF heat shrink film cutting device to solve the problem mentioned in the background art that the cutting blade is designed with an inclination but no limiting mechanism is set, which makes the cutting blade easy to lift up during cutting and has a certain degree of loosening.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a POF heat shrink film cutting device, including a base;

[0007] Also includes:

[0008] A fixed frame is installed on the upper end of the base. An installation rod is installed inside the fixed frame, and a tool holder is sleeved on the outside of the installation rod. The tool holder is inclined and has several pieces evenly distributed outside the installation rod. A blade is provided at the front end of the tool holder. An electric push rod is provided at the upper end of the fixed frame. A movable frame is installed inside the fixed frame. The movable frame is located on one side of the upper end of the tool holder, and the electric push rod is connected to the movable frame through a connecting rod. A roller is provided at the bottom of the movable frame. The roller rotates at the bottom of the movable frame through a rotating shaft, and the roller is movably in contact with the outer side of the tool holder.

[0009] Preferably, the front end of the tool holder is provided with a locking groove, the front end and the bottom of the locking groove are open, and the blade is movably locked inside the locking groove.

[0010] Preferably, the outer side of the tool holder is provided with a first threaded hole, and there are several first threaded holes. The first threaded holes are connected to the inside of the engagement groove. The blade is fixed inside the engagement groove by bolts. The bolts pass through the first threaded holes and engage with one side of the blade. The bolts are threadedly connected to the first threaded holes.

[0011] Preferably, the outer surface of the tool holder is provided with a circular hole, which connects the two sides of the tool holder, and the circular hole is slidably engaged with the mounting rod.

[0012] Preferably, the surface of the tool holder away from the blade is provided with a second threaded hole, and the second threaded hole communicates with the round hole. A screw is threadedly connected to the inside of the second threaded hole, and the screw passes through the second threaded hole and is connected to the mounting rod. A rotating handle is provided at the other end of the screw.

[0013] Preferably, a silicone pad is provided on the upper surface of the base, and the silicone pad is fixed to the upper surface of the base by adhesive.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) By setting a movable frame that can be raised and lowered above the tool holder, the movable frame is driven to move up and down by an electric push rod. Rollers are set at the bottom of the movable frame. When the tool holder is tilted, the rollers press against the outer side of the tool holder. The tool holder can be pressed down by the electric push rod, so that the blade head can press against the upper surface of the base. This can prevent the blade head from being loose and unable to contact the heat shrink film, thus preventing ineffective cutting. Raising the movable frame can adjust the position of the tool holder.

[0016] (2) By setting a locking groove at the front end of the tool holder, the blade can be movably locked inside the locking groove and fixed with bolts, so that the blade can be replaced and disassembled. At the same time, a locking structure is set at the rear end of the tool holder. The locking structure consists of a screw and a rotating handle. The screw passes through the threaded hole and abuts against one side of the mounting rod, so that the position of the tool holder can be adjusted, further improving the stability and firmness of the tool holder and preventing the tool holder from loosening.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] This utility model provides a POF heat shrink film cutting device, which includes a base 1. The main problem this utility model addresses is that the cutting blade is designed at an angle but lacks a limiting mechanism, making it prone to lifting during cutting and exhibiting a certain degree of looseness.

[0024] For the device provided by this utility model, please refer to Figures 1-4 The following is a detailed introduction.
