Description

Technical Field

[0001] This utility model relates to the technical field of plastic film preparation equipment, specifically to a plastic film device with an adjustable blade. Background Technology

[0002] Plastic film preparation refers to the process of processing plastic granules into plastic films, usually using the blow molding method. The blow molding method involves heating plastic granules or powder to melt them, and then blowing the molten plastic into a film using a blow molding machine.

[0003] A blown film machine is a plastic film processing device that heats and melts plastic particles, then blows them into a film. The film blown out through a die and air ring is typically a cylindrical film, which then passes through a herringbone plate to obtain a sheet-like finished film with a two-layer structure.

[0004] Existing blown film machines use a rewinder to collect the resulting sheet film. Since the collected sheet film is obtained by flattening a circular film, the two layers are connected together, which is inconvenient to use and requires cutting with a blade. The current cutting process is generally carried out manually, which is not only inefficient but also lacks cutting precision, affecting the subsequent use of the film. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable cutting edge plastic film device to solve the problems of low precision and low efficiency when cutting sheet-like films.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an adjustable cutting edge plastic film device, including a blown film machine and a transport frame, including a horizontal mounting plate, a left adjustment component and a right adjustment component;

[0007] A horizontal mounting plate is connected to both ends of the transport frame;

[0008] The left adjustment component includes an electric push rod and a blade; the electric push rod is located at the left end of the horizontal mounting plate, the telescopic rod is horizontally positioned to the right, and the blade is located at the front end of the telescopic rod;

[0009] The right adjustment component and the left adjustment component have the same structure and are symmetrically arranged at the right end of the horizontal mounting plate;

[0010] Adjust the position of the blades of the left and right adjustment components to cut the sheet-like film.

[0011] As a further technical solution to the above solution, the horizontal mounting plate is also provided with a scale.

[0012] As a further technical solution of the above solution, the sheet film is cut to form a front film and a back film, and also includes a first collection component and a second collection component; the first collection component is disposed at the lower front end of the transport frame and includes a winding roller and a placement frame; the winding roller is placed on the placement frame for winding the front film separated after cutting; the second collection component is disposed at the lower rear end of the transport frame for collecting the back film separated after cutting.

[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects: By setting the electric push rods of the left and right adjustment components to extend and retract, this utility model drives the adjustment of the position of the two blades on the horizontal mounting plate, thereby adjusting the cutting position of the blade edge; by changing the distance between the two blades, both ends of the sheet film are cut; by controlling the movement position of the electric push rod, the sheet film can be precisely cut, thus improving the cutting accuracy.

[0014] This device is directly mounted on the transport frame to cut sheet films directly, resulting in cut front and back films, which improves work efficiency. Attached Figure Description

Detailed Implementation

[0018] 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, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0019] like Figure 1 and Figure 2 As shown, an adjustable cutting edge plastic film device includes a blown film machine and a transport frame 1, including a horizontal mounting plate 2, a left adjustment component 3 and a right adjustment component 4;

[0020] The horizontal mounting plate 2 is connected to both ends of the transport frame 1;

[0021] The left adjustment component 3 includes an electric push rod 31 and a blade 32; the electric push rod 31 is located at the left end of the horizontal mounting plate 2, the telescopic rod is horizontally positioned to the right, and the blade 32 is located at the front end of the telescopic rod.

[0022] The right adjustment component 4 and the left adjustment component 3 have the same structure and are symmetrically arranged at the right end of the horizontal mounting plate 2;

[0023] Adjust the position of the blade 32 of the left adjustment component 3 and the right adjustment component 4 to cut the sheet-like film.

[0024] When using this device, the plastic particles are first heated and melted, and then blown into a certain shape, usually a cylindrical pile, using a blown film machine. A film-collecting clamp is then used to gather and clamp the plastic particles, flattening them into a sheet film. The sheet film is transported by adjusting the direction using multiple transport rollers. The use of transport rollers on the transport frame 1 is existing technology and will not be elaborated here. The sheet film is transported horizontally on the transport frame 1. A horizontal mounting plate 2 is installed, and the electric push rod 31 is activated to move the blade 32. The blade 32 presses against the sheet film, with the blade edge vertical and in the same direction as the transport of the sheet film. The blade 32 moves to different positions to cut the sheet film into different widths. The left and right adjustment components cut the left and right ends of the sheet film respectively, obtaining the cut front and back films for easy collection and use. The electric push rod 31 precisely controls the movement of the blades, effectively controlling the blade distance and achieving width control of the sheet film. Furthermore, the blade 32 can be directly used to cut the sheet film during transport, directly obtaining the cut front and back films, improving work efficiency.

[0025] like Figure 2 As shown, in a preferred embodiment, the horizontal mounting plate 2 is also provided with a scale 5. In this embodiment, the scale 5 is provided above the horizontal mounting plate 2. During the movement of the blade 32, the reading of the scale 5 is used to further confirm the accuracy of the movement and ensure that the cut film width meets the requirements.

[0026] like Figure 1 As shown, in a preferred embodiment, the sheet film is cut to form a front film and a back film; it also includes a first collecting component 6 and a second collecting component 7; the first collecting component 6 is located at the lower front end of the transport frame 1, including a winding roller 61 and a placement frame 62; the winding roller 61 is placed on the placement frame 62 for winding the separated front film after cutting; the second collecting component 7 is located at the lower rear end of the transport frame 1 for collecting the separated back film after cutting. In this embodiment, the first collecting component 6 and the second collecting component 7 are respectively used to collect the cut front film and back film, and the front film and back film are wound on the winding roller 61. As the winding roller 61 rotates, the front film and back film are smoothly wound on the winding roller 61, and the front film and back film are collected separately for subsequent use. In actual use, the placement frame 62 can be provided with multiple slot structures for placing the winding roller 61. When one winding roller 61 finishes winding, another winding roller 61 is placed in to continue winding, and the film cut off from the previous winding roller 61 is covered on the new winding roller 61.

[0027] The terms "connection" and "fixing" appearing in this utility model description can refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meaning of the above terms in this utility model should be understood according to the specific circumstances.
