Description

Technical Field

[0001] This utility model relates to the field of cast film processing technology, and in particular to a cast film slitting machine. Background Technology

[0002] Cast film is a type of non-stretched, non-oriented flat extruded film produced by melt casting and cold extrusion. Compared with blown film, it is characterized by fast production speed, high output, good film gloss, and uniform thickness. As a type of cast film, CPE film is extremely convenient for subsequent processes such as printing and lamination due to its flat extrusion nature. Therefore, it is widely used in the packaging of textiles, industrial products, food, and daily necessities.

[0003] In the production process, cast film is generally directly extruded into a continuous strip with a relatively wide transverse width. Then, according to the customer's size requirements, the continuous cast film is cut according to the set width and length to obtain cast film sheets with the same size as the customer. However, the existing cast film slitting machine has a complex overall structure, the width of the cut cast film cannot be adjusted for personalization, and the cutting effect and cutting precision cannot well meet the user's needs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a slitting machine for cast film, thereby solving the problems mentioned in the background section.

[0005] A casting film slitting machine includes a support frame, two rollers mounted opposite each other on the support frame, and a slitting mechanism mounted on the support frame. The slitting mechanism includes a motor, a bidirectional lead screw, a fixed rod, a sliding part, a movable rod, an electric cylinder, a fixed head, a first slice, a second slice, a scale, and a connecting rod. The bidirectional lead screw is mounted at the output end of the motor. Two sliding parts are provided and slide along the fixed rod fixed on the support frame. The connecting rod passes through the sliding parts. The movable rod passes through the connecting rod and slides along a groove at the upper end of the support frame, and is pushed and pulled up and down by the electric cylinder mounted on the support frame. The fixed head is fixed to the bottom end of the connecting rod. The first slice is rotatably mounted on one of the fixed heads, and the second slice is adjustablely mounted on the other fixed head through an adjustment component. The scale passes through the sliding part, and its two ends extend and are fixed to the support frame.

[0006] By adopting the above technical solution, the device can quickly and easily adjust the slice to the predetermined position as needed, and can cut the cast film into different widths as required.

[0007] The adjusting assembly consists of a screw and a nut. The screw passes through a corresponding fixed head, and there are two nuts used to lock the screw onto the fixed head.

[0008] By adopting the above technical solution, it is possible to cut different widths.

[0009] The slitting mechanism is positioned above the two rollers.

[0010] The above technical solution facilitates the cutting of the cast film.

[0011] The upper end of the bracket is provided with a sliding groove, and the upper end of the sliding part slides in the sliding groove.

[0012] By adopting the above technical solution, the sliding part can be moved, and the connecting rod can move up and down normally.

[0013] The connecting rod is positioned on the central axis of the two rollers.

[0014] By adopting the above technical solution, the slice one and slice two are controlled to move up and down, so that the cast film is cut by slice one and slice two.

[0015] The beneficial effects of this utility model of a casting film slitting machine are:

[0016] The cast film is drawn onto the roller, and the external limiting and anti-deviation mechanism is adjusted to ensure that the cast film does not deviate when passing through the roller. Then, the distance between the two slices can be adjusted according to the required cutting width of the cast film. Since the required cutting width may vary, the nut on the screw can be rotated to adjust the position of the screw on the fixed head, so that the corresponding slice can be moved to the cutting position. This device allows for quick and easy adjustment of the slice to the predetermined position as needed, and the cast film can be cut into different widths as required. Attached Figure Description

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0021] Reference Figure 1-2A casting film slitting machine includes a support 1, two rollers 2 mounted opposite each other on the support 1, and a slitting mechanism mounted on the support 1. The slitting mechanism includes a motor 3, a bidirectional lead screw 4, a fixed rod 5, a sliding part 6, a movable rod 7, an electric cylinder 8, a fixed head 9, a first slice 10, a second slice 12, a scale 13, and a connecting rod 14. The bidirectional lead screw 4 is mounted at the output end of the motor 3. There are two sliding parts 6, which slide along the fixed rod 5 fixed on the support 1. The connecting rod 14 passes through the sliding part 6. The movable rod 7 passes through the connecting rod 14 and slides along the slide groove 101 at the upper end of the support 1. It is pushed and pulled up and down by the electric cylinder 8 mounted on the support 1. The fixed head 9 is fixed to the bottom end of the connecting rod 14. The first slice 10 is rotatably mounted on one of the fixed heads 9. The second slice 12 is adjustablely mounted on the other fixed head 9 through an adjustment component. The scale 13 passes through the sliding part 6, and its two ends extend and are fixed to the support 1.

[0022] The cast film is pulled onto the roller 2. The external mechanism that limits and prevents deviation of the cast film is adjusted so that the cast film does not deviate when passing through the roller 2. Then, the distance between the two slices 10 can be adjusted according to the required width of the cast film. The motor 3 drives the two sliding parts 6 to move along the fixed rod 5 through the bidirectional lead screw 4. The scale 13 is observed until the two slices 10 are moved to the predetermined position. The connecting rod 14 is set on the central axis of the two rollers 2. The electric cylinder 8 pulls the movable rod 7 downward. The movable rod 7 drives the fixed head 9 downward through the connecting rod 14, so that the slice 10 is moved to the position for cutting the cast film.

[0023] Since the required cutting width may vary, the nut on the screw 11 can be rotated to adjust the position of the screw 11 on the fixed head 9, so that the corresponding slice 12 can be moved to the cutting position.

[0024] This device allows for quick and easy adjustment of the slice 10 to a predetermined position as needed, and can cut the cast film into different widths as required.

[0025] The adjustment component consists of a screw 11 and a nut. The screw 11 passes through a corresponding fixed head 9, and there are two nuts used to lock the screw 11 onto the fixed head 9. An adjustment component is set on one of the fixed heads 9 to adjust the position of the second slice 12, thereby controlling the different widths of the slit cast film.

[0026] The slitting mechanism is located above the two rollers 2. When the cast film passes over the rollers 2, it is in a taut state so that the slitting mechanism can slit it from between the two rollers 2.

[0027] A sliding groove is provided at the upper end of the bracket 1, and the upper end of the sliding part 6 slides in the sliding groove; the sliding groove is provided, and the movable rod 7 and the connecting rod 14 are slidably connected so that the connecting rod 14 can be adjusted synchronously, so that the sliding part 6 can move and the connecting rod 14 can move up and down.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
