[0005] When the cutting machine is working, the staff needs to place the PVC film first, and then the staff's working state will affect the tiling effect of the PVC film. The device in the above application does not have the function of auxiliary reminder during use. If the staff is not focused, it will directly affect the cutting accuracy and bring unnecessary trouble to the cutting work of the PVC film.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original PVC film automatic cutting machine. Utility Model Content

[0008] To achieve the above object, the utility model provides the following technical solution: a high-precision automatic cutting machine for PVC film production, comprising a working plate, a bracket is fixedly connected to the lower surface of the working plate, a vertical rod is bolted to the upper surface of the working plate, and a slider is slidably connected to the inside of the vertical rod through an electric slide rail;

[0009] A pressure rod is fixedly connected to the surface of the sliding block;

[0010] The upper surface of the working plate is fixedly connected with a column, and the interior of the column is slidably connected with a cutting knife via an electric slide rail, and the surface of the column is fixedly connected with a side plate;

[0011] A protective shell is slidably provided on the surface of the side plate;

[0012] The upper surface of the working plate is fixedly connected with a vertical plate, the surface of the vertical plate is fixedly connected with a cross bar, the surface of the cross bar is slidably connected with a movable plate, and the surface of the movable plate is fixedly connected with a knocking block.

[0013] Preferably, an auxiliary plate is fixedly connected to the upper surface of the working plate, and an auxiliary rod is rotatably provided on the surface of the auxiliary plate, and the end of the auxiliary rod is convex.

[0020] Preferably, the knocking blocks are distributed at equal intervals on the surface of the movable plate.

[0021] Compared with the prior art, the utility model has the following beneficial effects: the high-precision automatic cutting machine for PVC film production adopts a new structural design, and its specific contents are as follows:

[0022] (1) The high-precision automatic cutting machine for PVC film production has protective shells on both sides of the cutting blade. The cutting blade is covered, so that dust will not fall on the surface of the cutting blade. When the cutting blade is working, the cutting work will not be affected by dust, which ultimately improves the cutting accuracy.

[0023] Furthermore, after the PVC film is evenly laid on the working board, the slider is lowered inside the vertical rod under the action of the electric slide rail, so that the pressure rod presses the PVC film, and then when the PVC film is cut, there is no displacement, thereby improving the cutting accuracy;

[0024] (2) In the high-precision automatic cutting machine for PVC film production, when the slider descends, the slider drives the protective shell to move away from the cutting knife through the long rod and the traction rope. At this time, the cutting knife is opened, that is, when cutting is required, the cutting knife can work normally and will not affect the cutting of the PVC film;

[0025] Furthermore, during the movement of the protective shell, the overlap block will slide inside the side plate, and at this time, the limit rod makes the side plate and the protective shell move only in the horizontal direction, thereby ensuring stability;

[0026] (3) In the high-precision automatic cutting machine for PVC film production, during the movement of the overlapping block, the first magnet will intermittently approach the second magnet. At this time, the movable plate will make reciprocating linear motion in the horizontal direction under the action of the mutual magnetic force, the connecting spring and the cross bar. At this time, the movable plate will drive the knocking block to move synchronously. At this time, the knocking block will hit the vertical plate again and again. At this time, the vertical plate and the knocking block play the role of sound reminder, that is, when the protective shell is opened, before the PVC film is laid flat, it plays a role in concentrating the staff's attention, so that the PVC film is laid flatter, and the cutting accuracy is improved.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0036] Embodiment 1: By setting the pressure rod 4, the PVC film will not be lifted after being laid flat, ensuring the stability of the PVC film when being cut, thereby improving the cutting accuracy. At the same time, by setting the protective shell 7, the surface of the cutting knife 6 will not accumulate dust, which also improves the cutting accuracy. Figure 1-Figure 4 As shown:

[0037] It includes a working plate 1, a bracket is fixedly connected to the lower surface of the working plate 1, a vertical rod 2 is bolted to the upper surface of the working plate 1, and a slider 3 is slidably connected to the inside of the vertical rod 2 through an electric slide rail, and a pressure rod 4 is fixedly connected to the surface of the slider 3;

[0038] The upper surface of the working plate 1 is fixedly connected with a column 5, and the interior of the column 5 is slidably connected with a cutting knife 6 via an electric slide rail, and the surface of the column 5 is fixedly connected with a side plate 14, and the surface of the side plate 14 is slidably provided with a protective shell 7;

[0039] A vertical plate 15 is fixedly connected to the upper surface of the working plate 1, and a cross bar 16 is fixedly connected to the surface of the vertical plate 15, and a movable plate 17 is slidably connected to the surface of the cross bar 16, and a knocking block 18 is fixedly connected to the surface of the movable plate 17, and an auxiliary plate 8 is fixedly connected to the upper surface of the working plate 1, and an auxiliary rod 9 is rotatably provided on the surface of the auxiliary plate 8, and the end of the auxiliary rod 9 is convex.

[0040] The end of the slider 3 is fixedly connected to a long rod 22, and the surface of the long rod 22 is fixedly connected to a traction rope 10, and the end of the traction rope 10 is fixedly connected to the outer wall of the protective shell 7, the surface of the traction rope 10 is in contact with the surface of the auxiliary rod 9, and a limiting rod 12 is fixedly connected to the inner wall of the side panel 14, and the surface of the limiting rod 12 is sleeved with a lap block 11, and the surface of the lap block 11 is fixedly connected to the side of the protective shell 7.

[0041] Initially, the protective shell 7 is located on both sides of the cutting knife 6. At this time, the cutting knife 6 is covered, and no dust will fall on the surface of the cutting knife 6. When the cutting knife 6 is working, the cutting work will not be affected by the dust, which ultimately improves the cutting accuracy. After the PVC film is evenly laid on the working board 1, the slider 3 descends inside the vertical rod 2 under the action of the electric slide rail, so that the pressure rod 4 presses the PVC film, and then when the PVC film is cut, there is no displacement, which improves the cutting accuracy. When the slider 3 descends, the slider 3 drives the protective shell 7 to move away from the cutting knife 6 through the long rod 22 and the traction rope 10. At this time, the cutting knife 6 is opened, and the cutting work can be completed normally (in this process, the auxiliary plate 8 and the auxiliary rod 9 maximize the pulling force of the traction rope 10).

[0042] Embodiment 2: Different from Embodiment 1, the first spring 13 can be provided to return the protective shell 7 to its original position when the cutting knife 6 is not needed, so that the protective shell 7 covers the cutting knife 6 again. Figure 3 As shown:

[0043] A first spring 13 is fixedly connected to the surface of the connecting block 11 , and the other side of the first spring 13 is fixedly connected to the inner wall of the side plate 14 .

[0044] When the protective shell 7 moves away from the cutting knife 6, the overlapping block 11 will slide inside the side plate 14 under the action of the limiting rod 12. At this time, the first spring 13 will be squeezed. When the slider 3 rises, the protective shell 7 loses the pulling force of the traction rope 10. At this time, the protective shell 7 moves back under the action of the first spring 13. Finally, the protective shell 7 will cover the cutting knife 6 again, thereby playing a dust-proof role.

[0045] Embodiment 3: Different from Embodiment 2, the knocking block 18 and the vertical plate 15 can play the role of sound reminder, so that the staff can concentrate before laying the PVC film. Figure 6 and Figure 7 As shown:

[0046] A first magnet 19 is fixedly connected to the end of the overlapping block 11, a second magnet 21 is fixedly connected to the surface of the movable plate 17, and the magnetic poles of the second magnet 21 and the first magnet 19 at adjacent positions are opposite, and the second magnet 21 is evenly spaced on the surface of the movable plate 17, the end of the cross bar 16 is convex, and a connecting spring 20 is fixedly connected to the inner wall of the cross bar 16, and the other side of the connecting spring 20 is fixedly connected to the outer wall of the movable plate 17, and the knocking blocks 18 are evenly spaced on the surface of the movable plate 17.

[0047] During the movement of the overlapping block 11, the first magnet 19 will intermittently approach the second magnet 21. When the first magnet 19 approaches the second magnet 21, the movable plate 17 moves in the direction of squeezing the connecting spring 20 under the action of the mutual magnetic force. When the first magnet 19 is away from the second magnet 21, the movable plate 17 returns to its original position under the action of the connecting spring 20. The above process is repeated. The movable plate 17 performs reciprocating linear motion in the horizontal direction under the action of the mutual magnetic force, the connecting spring 20 and the cross bar 16. At this time, the movable plate 17 will drive the knocking block 18 to move synchronously. At this time, the knocking block 18 will hit the vertical plate 15 again and again. At this time, the vertical plate 15 and the knocking block 18 play the role of sound reminder, that is, when the protective shell 7 is opened, before the PVC film is laid flat, it plays the role of concentrating the staff's attention, so that the PVC film is laid better and the cutting accuracy is improved.

[0048] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
