Description

Technical Field

[0001] This invention relates to the field of thin film production technology, and in particular to a spiral slitting machine with adaptive cylinder diameter and dual follower barrels. Background Technology

[0002] In current film production and processing, the film rolls are usually first fitted onto the cutting mechanism. However, the folded diameter of the freshly produced films varies, but it is required that the width of each roll of film cut is the same. Therefore, in order to meet the film cutting requirements, the film cutting equipment needs to be redesigned to ensure that the cut films have the same width, preventing inconsistent widths during the cutting process, and thus meeting customer needs.

[0003] Existing film cutting equipment barrel mechanisms are mostly single cylindrical structures. For example, patent application number 2019201560583 discloses a three-dimensional spiral slitting machine telescopic sensing device. When the diameter of the cylindrical film is larger than the diameter of the barrel, the film cannot be tensioned, which leads to cutting failure or film edge tearing caused by cutting. This patent cannot be applied to situations where the diameter of the cylindrical film changes.

[0004] Patent application number 2012205363173 discloses a two-half elliptical barrel, which is divided into a fixed shaping cylinder and an adjusting cylinder for adjusting the focal length. The adjustment is achieved by a worm gear mechanism. This patent does not describe the dynamic adjustment during the working process.

[0005] In summary, existing slitting machines cannot achieve symmetrical expansion or contraction of the left and right half-cylinders to accommodate film of different radii, resulting in inconsistent widths of the cut sheet films. This leads to a large amount of waste material in subsequent film cutting processes, causing a certain degree of product waste. Summary of the Invention

[0006] The purpose of this invention is to provide a spiral slitting machine with adaptive cylinder diameter and dual follower barrels.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows:

[0008] A spiral slitting machine with adaptive cylinder diameter and dual follow-up barrels is characterized in that it includes a frame, a blade holder, and a barrel mechanism. The blade holder and the barrel mechanism are both fixed on the frame. The blade holder is equipped with a laser cutting head. The barrel mechanism includes an adjustable mechanism, a supporting square steel and a spring mounting bracket. The supporting square steel is located at the central axis of the barrel mechanism. A left fixed bracket and a right fixed bracket are symmetrically arranged on both sides of the supporting square steel.

[0009] The adjustable mechanism includes an axial guide rail and several transverse guide rails. The axial guide rail is fixed to the supporting square steel. Two axial rolling sliders are provided at the front and rear ends of the axial guide rail. The transverse guide rails are arranged perpendicular to the central axis of the barrel mechanism. Two transverse sliders are provided at the left and right ends of each transverse guide rail.

[0010] The left fixed frame has a left fixed plate on its inner side, and the right fixed frame has a right fixed plate on its inner side. Two transverse sliders are fixedly connected to the left fixed plate and the right fixed plate respectively. Connecting blocks are provided on the front and rear sides of the left fixed plate and the right fixed plate. The connecting blocks are connected to the axial rolling slider through a connecting rod.

[0011] The spring mounting bracket is equipped with springs, which are symmetrically distributed on the left and right sides of the supporting square steel. When the spring is compressed, it drives the transverse slider to move along the transverse guide rail toward the axis, thereby driving the connecting block to move closer to the axis. When the connecting block moves closer to the axis, the two axial rolling sliders move away from each other along the axial guide rail through the linkage.

[0012] Furthermore, the barrel mechanism includes a left adjusting cylinder and a right adjusting cylinder, which are circumferentially closed and connected. The left adjusting cylinder is fixed to the outside of the left fixed frame, and the right adjusting cylinder is fixed to the outside of the right fixed frame.

[0013] Furthermore, the left and right adjusting cylinders have a semi-circular arc structure.

[0014] Furthermore, two connecting blocks are symmetrically distributed on both sides of the left fixed plate. One end of the left connecting rod of the supporting square steel is hinged to the connecting block on one side of the left fixed plate, and the other end of the left connecting rod is hinged to the axial rolling slider. One end of the right connecting rod of the supporting square steel is hinged together with the left connecting rod on the axial rolling slider, and the other end of the right connecting rod is hinged to the connecting block on one side of the right fixed plate.

[0015] Furthermore, the connecting rod and the connecting block, as well as the connecting rod and the axial rolling slider, are all hinged by pins.

[0016] Furthermore, the supporting square steel is provided with several adjustable mechanisms and several spring mounting brackets arranged sequentially along the axial direction.

[0017] This invention utilizes a linkage structure to simultaneously expand and contract the left and right adjusting cylinders, adapting to film tubes of different radii. It ensures that the left and right semi-circular adjusting cylinders always adaptively and symmetrically open and close, thus expanding the film tube. The laser blade of the cutter holder then cuts the unwound film tube, achieving precise cutting of the film tube and solving the problem of uneven end faces of the cut film. This also enables greater tolerance for variations in the fold diameter of the film tube. Attached Figure Description

[0028] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] This invention discloses a spiral slitting machine with adaptive barrel diameter and dual follower function, such as... Figure 1 As shown, it includes a frame 1, a tool holder 2, and a barrel mechanism 3. The tool holder 2 is mounted on the frame 1, and the barrel mechanism 3 is mounted on the frame 1.

[0030] like Figure 2 and Figure 3 As shown, the barrel mechanism 3 includes a left adjusting cylinder 301, a right adjusting cylinder 302, an adjustable mechanism 303, a supporting square steel 304, a left fixed frame 305, a right fixed frame 306, and a spring mounting frame 307. The supporting square steel 304 is located at the central axis inside the barrel mechanism 3. The left adjusting cylinder 301 and the right adjusting cylinder 302 have a semi-circular structure. The left fixed frame 305 and the right fixed frame 306 are symmetrically installed on the left and right sides of the supporting square steel 304. The left adjusting cylinder 301 is fixed on the left fixed frame 305, and the right adjusting cylinder 302 is on the right fixed frame 306.

[0031] like Figure 4 As shown, the adjustable mechanism 303 includes an axial guide rail 30301, an axial rolling slider 30302, a transverse guide rail 30303, and a connecting rod 30305. The axial guide rail 30303 is mounted on the supporting square steel 304, and the axial rolling slider 30302 is mounted on the axial guide rail 30301. Each axial guide rail 30301 is provided with two axial rolling sliders 30302.

[0032] The transverse guide rail 30303 is perpendicular to the central axis of the barrel mechanism 3 and is set on the supporting square steel 304, such as... Figure 3 As shown, there are at least two transverse guide rails 30303, which are arranged in parallel to each other. Each transverse guide rail 30303 has a left transverse slider and a right transverse slider 30304 at its left and right ends, respectively. The left transverse slider is installed together with the left fixing plate 30501 inside the left fixing frame 305, which drives the left fixing frame 305 to move and adjust. The right transverse slider 30304 is installed together with the right fixing plate 30601 inside the right fixing frame 306, which drives the right fixing frame 306 to move and adjust.

[0033] like Figure 4 As shown, two symmetrical connecting blocks 30502 are provided on both sides of the left fixed plate 30501 and the right fixed plate 30601, for a total of four connecting blocks 30502. One end of the two connecting rods 30305 on the left side of the supporting square steel 304 is hinged to the two connecting blocks 30502 on the side of the left fixed plate 30501 via pins 30306. The other end of the left connecting rod 30305 is hinged to the two axial rolling sliders 30302 via pins 30306. One end of the two connecting rods 30305 on the right side of the supporting square steel 304 is hinged to the axial rolling sliders 30302 via pins 30306, sharing a common node with the left connecting rod 30305. The other end of the right connecting rod 30305 is hinged to the two connecting blocks on the side of the right fixed plate 30601 via pins 30306.

[0034] The spring mounting bracket 307 is equipped with a spring 30701, which is located on the left and right sides of the supporting square steel 304. When the spring 307 is compressed, the left adjusting cylinder 301 and the right adjusting cylinder 302 move towards the axis center through the movement of the left transverse slider and the right transverse slider 30304 along the transverse guide rail 30303, so that the two axial rolling sliders 30302 slide towards the front and rear ends of the axial guide rail 30301. Since the connecting rods 30305 on the left and right sides share a common node with the axial rolling sliders 30302, the connecting rod 30305 on the right side drives the right adjusting cylinder 302 to move towards the axis center, realizing the dual follow-up of the adaptive cylinder diameter of the spiral slitting machine barrel.

[0035] The supporting square steel 304 can be arranged with multiple adjustable mechanisms 303 and multiple spring mounting brackets 307 in sequence along the axial direction, so as to more smoothly realize the dual follow-up function of the left and right adjustment cylinders.

[0036] The blade holder 2 is equipped with a laser cutting head for cutting the unwound film, achieving precise cutting of the film and ensuring that the cut film has a consistent width and is not easily broken.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
