Description

Technical Field

[0001] The present application belongs to the technical field of film slitting, and in particular relates to a film slitting machine. Background Art

[0002] Films are divided into polyester films, aluminized films, BOPPLDPE, HDPE, LLDPE, PP, etc., and the film slitting machine is a device used to split the film.

[0003] For example, a film slitting machine cutter with authorization announcement number CN218614451 U has a cylindrical handle, which includes an upper cylinder and a lower cylinder. The lower end of the upper cylinder is evenly provided with several metal spring sheets along its axial direction. The metal spring sheets are strip-shaped, and the length direction of the metal spring sheets is the same as the length direction of the handle. A clamping block is provided at the end of the metal spring sheet. The upper end of the upper cylinder is connected to the blade through several connecting rods. The blade is circular. The length direction of the connecting rod is perpendicular to the length direction of the handle in the same plane. The number of connecting rods and metal spring sheets is the same and the length direction is on the same straight line. An opening is provided above the lower cylinder for use with the clamping block.

[0004] The above patent adjusts and fixes the cutter by adjusting the bolts, the rectangular tube and the rectangular plate. However, since multiple adjustments are required, the bolts and the rectangular tube need to be frequently tightened and loosened. Over time, this will cause thread wear and make it impossible to tighten the cutter. Replacing the corresponding parts will cause unnecessary losses, and improvements are needed. Utility Model Content

[0005] The purpose of this application is to provide a film slitting machine that can solve the above problems.

[0006] The purpose of this application is to provide a film slitting machine, comprising:

[0007] frame;

[0008] The guiding device comprises vertical plates arranged at intervals, an unwinding roller arranged between the vertical plates, a first transition roller, a second transition roller and a winding roller;

[0009] The cutting device comprises a slitting knife, an adjusting plate and a mounting mechanism connecting the slitting knife and the adjusting plate;

[0010] The slitting knife is installed on the adjusting plate through the installation mechanism and can slide along the length direction of the adjusting plate, and the adjusting plate is provided with a scale.

[0011] By adopting the above-mentioned film slitting machine installation mechanism, the film slitting work can be completed through the coordinated use of the vertical plate, the unwinding roller, the first transition roller, the second transition roller, the winding roller and the cutting device. By setting a scale on the adjustment plate, the operator can accurately adjust the position of the slitting knife according to production needs, ensuring that the film is accurately cut according to the set width or shape, which can meet different production needs and improve the product qualification rate. The slitting knife is installed on the adjustment plate through the installation mechanism and can slide along the length direction of the adjustment plate, which allows the operator to quickly adjust the position of the slitting knife as needed. Through the setting of the installation mechanism, the slitting knife can be easily installed on the adjustment plate, so that when the slitting knife needs to be replaced, the damaged and worn replacement plate can be easily replaced, which effectively saves time and reduces losses.

[0012] Furthermore, the installation mechanism includes:

[0013] An adjusting sleeve, wherein a through slot is provided inside the adjusting sleeve for the adjusting plate to pass through;

[0014] A contact groove is arranged on the adjustment plate, and the contact groove is in a long strip shape;

[0015] A mounting groove is provided on the adjustment plate, wherein a replacement plate is provided in the mounting groove;

[0016] A fastener, one end of which is provided with a limit portion and the other end of which is provided with a thread;

[0017] There are multiple installation grooves, and the multiple installation grooves are evenly distributed according to scales. The fastener passes through the adjustment sleeve, the contact groove, and the adjustment plate and is connected to the replacement plate.

[0018] The adjustment sleeve can be slidably mounted on the adjustment plate, and the slitting knife is fixed on the adjustment plate by fasteners, which simplifies the installation and adjustment process and improves work efficiency. Since the installation slots are evenly distributed according to the scale, the operator can accurately adjust the position of the slitting knife according to the scale to achieve high-precision cutting. The design of the replacement plate makes it possible to replace the slitting knife by simply loosening the fasteners, removing the old replacement plate, and then installing the new replacement plate. The threaded holes set on the replacement plate and other parts will not contact the threads of the fasteners, and will not be damaged even if they are disassembled for a long time and multiple times, effectively reducing the losses caused by maintenance and replacement of parts.

[0019] In addition, the entire installation mechanism is simple and clear. The operator only needs to adjust the position of the slitting knife according to the scale and fix it with fasteners. There is no need for complicated operating steps or professional tools, which reduces the difficulty of operation.

[0020] Further: the installation mechanism also includes:

[0021] A first through hole is provided on the adjusting sleeve;

[0022] A second through hole is disposed on the contact groove;

[0023] A threaded hole is provided on the replacement plate;

[0024] The fastener passes through the first through hole and the second through hole and is connected to the threaded hole, and a first gap and a second gap are respectively provided between the first through hole, the second through hole and the fastener.

[0025] The fastener passes through the first through hole and the second through hole and is connected to the threaded hole on the replacement plate, ensuring that the slitting knife can be stably fixed on the adjustment plate, providing a reliable fixing force, and reducing the possibility of the slitting knife loosening or shifting during the cutting process. Since the first through hole, the second through hole and the fastener are respectively provided with a first gap and a second gap, the fastener will not contact the inner wall of the first through hole and the second through hole during the loosening and tightening process, thereby avoiding friction and wear between them, effectively protecting the fastener, the adjustment sleeve and the adjustment plate, and extending the service life. When the slitting knife needs to be replaced, the operator only needs to loosen the fastener, remove the old replacement plate and the slitting knife, and then install the new replacement plate and the slitting knife on the adjustment plate and fix them with the fastener. The entire replacement process is simple and quick, reducing downtime.

[0026] Furthermore, an inner ring body is provided at one end of the second through hole away from the bolt hole, and a hole for the fastener to pass through is provided at the center of the inner ring body;

[0027] The fastener is provided with an outer ring body, the diameter of the outer ring body is smaller than the inner diameter of the first through hole;

[0028] Wherein, an elastic member is arranged between the inner ring body and the outer ring body.

[0029] During the installation of the fastener, the outer ring body will approach the inner ring body as the fastener is gradually tightened, and gradually squeeze the elastic part during the approach process. After the fastener completely passes through the hole and is connected to the threaded hole, the squeezed elastic part will provide a certain pressure to ensure a tighter connection between the fastener and the replacement plate and maintain a stable fixing force. At the same time, it can also provide thrust during the removal of the fastener to assist the user to quickly loosen the fastener.

[0030] Furthermore, the adjusting sleeve is provided with a protrusion, a sealing cover is provided on the protrusion, a limiting hole is provided on the sealing cover, and the first through hole passes through the protrusion and is connected with the limiting hole.

[0031] The sealing cover can effectively prevent dust, moisture and other external impurities from entering the adjustment sleeve, thereby protecting the internal fasteners and other key components from contamination and damage. The design of the limit hole can limit the fasteners, thereby avoiding various problems caused by over-tightening or improper positioning. The convex and sealing cover design on the adjustment sleeve makes it easier for operators to find and operate fasteners when installing and adjusting the slitting knife, improving work efficiency.

[0032] Furthermore, the replacement plate is provided with a pull-out groove, and the installation groove is provided with a pull-out opening adapted to the pull-out groove.

[0033] By setting a pull-out groove on the replacement plate and opening a pull-out opening that matches the pull-out groove on the installation groove, the operator can easily pull out or insert the replacement plate through the cooperation of the pull-out groove and the pull-out opening, thereby quickly completing the replacement of the slitting knife, reducing the replacement time and improving work efficiency.

[0034] The beneficial effects of this application are:

[0035] 1. The slitting knife is installed on the adjustment plate through the installation mechanism and can slide along the length direction of the adjustment plate, which allows the operator to quickly adjust the position of the slitting knife as needed. Through the setting of the installation mechanism, the slitting knife can be easily installed on the adjustment plate, so that when the slitting knife needs to be replaced, the damaged and worn replacement plate can be easily replaced, which effectively saves time and reduces losses;

[0036] 2. The adjustment sleeve can be slidably mounted on the adjustment plate, and the slitting knife is fixed on the adjustment plate by fasteners, which simplifies the installation and adjustment process and improves work efficiency. The design of the replacement plate allows you to replace the slitting knife by simply loosening the fasteners, removing the old replacement plate, and then installing a new replacement plate. The threaded holes on the replacement plate and other parts will not contact the threads of the fasteners, and will not be damaged even if they are disassembled for a long time or multiple times, effectively reducing the losses caused by maintenance and replacement of parts;

[0037] 3. During the installation of the fastener, the outer ring body will approach the inner ring body as the fastener is gradually tightened, and gradually squeeze the elastic part during the approaching process. After the fastener completely passes through the hole and is connected to the threaded hole, the squeezed elastic part will provide a certain pressure to ensure that the connection between the fastener and the replacement plate is tighter and maintain a stable fixing force. At the same time, it can also provide thrust during the removal of the fastener to assist the user to quickly loosen the fastener. BRIEF DESCRIPTION OF THE DRAWINGS
