Description

Technical Field

[0001] This utility model belongs to the technical field of film processing equipment, and in particular relates to a glue supply and conveying device for film cutting. Background Technology

[0002] A film cutting machine is a rubber feeding and conveying device used for cutting film. It can stably and accurately convey rolls of film material according to a preset length or shape, and finally cut them into individual sheets for use in the next process. It solves the problems of low efficiency, poor precision, large waste, and poor consistency of traditional manual cutting, and is an indispensable piece of equipment in the production process of rubber products.

[0003] A search revealed that Chinese Patent (Publication No.: CN101602235A) discloses the film cutting machine and method described in this invention. This method utilizes the oscillating cutting between a rotating roller and a suspended roller. The extrusion cutting force of the roller on the roller surface is dynamically adjusted to protect the blade body, achieving a composite cutting method of shearing, extrusion, and tearing. This eliminates the heavy manual rubber cutting work and improves the overall automation rate of tire production. The film cutting machine has a frame, on which a roller cutting device and a conveying device are installed. The roller cutting device has an open housing, inside which a rotating roller is horizontally mounted via bearing seats on both sides. An oscillating mechanism is connected between the two side plates of the housing, and a cold rolling roller is suspended below the oscillating mechanism, reciprocating along its vertical centerline. The transverse centerline of the rotating roller coincides with the transverse centerline of the cold rolling roller. A negative gap is formed between the outer periphery of the cold rolling roller and the blade edge of the rotating roller.

[0004] Because the blades of this device are designed with a curved shape, in actual use, the blade holder with the blades rotates so that the surface-hardened roller is pushed by a large-sized disc spring to keep it in contact with the blade edge. During the engagement process, the film is sheared by the contact pressure between the blade and the roller. As a result, the blade will wear down continuously, which will increase the contact area between the blade and the roller, resulting in a decrease in the contact pressure between the blade and the roller. Ultimately, the film will not be cut. Therefore, a glue supply and conveying device for cutting film is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a glue supply and conveying device for film cutting, so as to solve the problems mentioned in the background art.

[0028] like Figures 1 to 4 As shown, this utility model embodiment provides a glue supply and conveying device for film cutting, comprising:

[0029] The device body 1 includes a base frame 11 and a longitudinal beam 12, with the longitudinal beam 12 fixedly installed at a predetermined distance above the base frame 11.

[0030] The cutting structure 2 includes a fixed blade 21, a pair of moving blades 22, a rotating shaft 23, and a fixed frame 24. The fixed blade 21 is installed at one end of the longitudinal beam 12, the rotating shaft 23 is inserted into the fixed frame 24, the pair of moving blades 22 are respectively inclinedly arranged on the opposite end faces of the fixed frame 24, and the axial directions of the pair of moving blades 22 are parallel to each other. Both the fixed blade 21 and the moving blades 22 are rectangular and are separated by a predetermined distance. The rotating shaft 23 is rotatably arranged on the longitudinal beam 12.

[0031] Tensioning structure 3 is installed on the main body 1 of the device;

[0032] Conveying structure 4 is installed on the main body 1 of the device;

[0033] In this embodiment, the rotating shaft 23 is driven by the driving device to rotate around its own axis, thereby causing the fixed frame 24 to also rotate around the rotating shaft 23 axis, which in turn causes the moving blades 22 placed on opposite sides of the fixed frame 24 to rotate synchronously. When the moving blades 22 rotate to the point where they have a shearing action with the fixed blades 21, the film is cut. In this embodiment, the driving device is implemented to include a motor, chain, etc. During the cutting process, the fixed blades 21 and the moving blades 22 will not come into direct contact, avoiding wear between the fixed blades 21 and the moving blades 22 and the generation of metal chips, thereby extending the service life of the equipment.

[0034] Specifically, the cutter structure 2 also includes multiple fixing plates 25, which are spaced apart and installed on the fixing frame 24, and the rotating shaft 23 is inserted into the multiple fixing plates 25;

[0035] In this embodiment, by setting multiple fixing plates 25, the rotating shaft 23 and the fixing frame 24 are fixed more firmly, ensuring the stability of the equipment operation;

[0036] Specifically, the cutter structure 2 also includes a pair of mounting plates 26, which are fixedly mounted on opposite end faces of the fixed frame 24. The mounting plates 26 are inclined and their axes are parallel to each other. Each moving blade 22 is detachably mounted on each mounting plate 26.

[0037] In this embodiment, when the moving blade 22 needs to be replaced, the worker can simply disassemble the entire moving blade 22 from the mounting plate 26; the operation is simple and the maintenance cost is low.

[0038] Specifically, the cutter structure 2 also includes two sets of reinforcing ribs 27, each set of reinforcing ribs 27 is provided with multiple ribs, and the multiple reinforcing ribs 27 are spaced apart between the side of the fixed frame 24 and the mounting plate 26;

[0039] In this embodiment, by providing reinforcing ribs 27, the mounting plate 26 and the moving blade 22 on the mounting plate 26 are more firmly fixed, further ensuring the stability of the equipment;

[0040] Specifically, the cutter structure 2 also includes a support plate 28, which is installed at one end of the longitudinal beam 12, and the fixed blade 21 is detachably installed on the support plate 28;

[0041] In this embodiment, when the fixed blade 21 needs to be replaced, the worker disassembles the entire fixed blade 21 from the pallet 28, which is simple to operate and has low maintenance costs.

[0042] Specifically, the conveying structure 4 includes an upper idler roller 41, a lower idler roller 42, and a pressing conveyor belt 43. The upper idler roller 41 and the lower idler roller 42 are rotatably mounted on the longitudinal beam 12, and the upper idler roller 41 is positioned at a predetermined distance above the lower idler roller 42. The pressing conveyor belt 43 is tractably mounted at a predetermined distance above the longitudinal beam 12.

[0043] In this embodiment, during use, the film in the film roller is bonded to the pressing conveyor belt 43 and placed between the upper idler roller 41 and the lower idler roller 42; the upper idler roller 41 applies appropriate pressure to the film to ensure that the film is always in a horizontal state; the lower idler roller 42 supports the film while also reducing the frictional resistance of the film during operation, thereby improving the smoothness of film conveying and extending the service life of the equipment; by setting the pressing conveyor belt 43 to press the surface of the film, it is prevented from shifting due to uneven tension or mechanical vibration during the conveying process, ensuring the accuracy of the cutting path.

[0044] The working principle of this utility model is as follows:

[0045] During use, the film in the film roller is in contact with the pressing conveyor belt 43 and placed between the upper idler roller 41 and the lower idler roller 42. The upper idler roller 41 applies appropriate pressure to the film to ensure that the film is always in a horizontal state. The lower idler roller 42 supports the film and also reduces the frictional resistance of the film during operation, thereby improving the smoothness of film conveying and extending the service life of the equipment. By setting the pressing conveyor belt 43 to press the surface of the film, it is prevented from shifting due to uneven tension or mechanical vibration during the conveying process, thus ensuring the accuracy of the cutting path.

[0046] Meanwhile, the tensioning structure 3 adjusts autonomously to further ensure that the film maintains stable tension during the cutting process, preventing the film from shifting or wrinkling during the cutting process; at this time, the middle section of the film passes through the cutting edge of the fixed blade 21.

[0047] At the same time, the rotating shaft 23 is driven by the driving device to rotate around its own axis, thereby causing the fixed frame 24 to also rotate around the rotating shaft 23 axis, which in turn causes the moving blades 22 placed on opposite sides of the fixed frame 24 to rotate synchronously. When the moving blades 22 rotate to the point that they have a shearing action with the fixed blades 21, the film is cut off. In this embodiment, the driving device is implemented to include a motor, chain, etc.

[0048] During the cutting process, the fixed blade 21 and the moving blade 22 are separated by a predetermined distance, and the fixed blade 21 and the moving blade 22 are in the shape of long strips, so that the cutting process of the film remains stable; in addition, the fixed blade 21 and the moving blade 22 will not come into direct contact, avoiding wear between the fixed blade 21 and the moving blade 22 and the generation of metal chips, thereby extending the service life of the equipment.

[0049] In addition, when the fixed blade 21 needs to be replaced, the worker can disassemble the entire fixed blade 21 from the support plate 28; when the moving blade 22 needs to be replaced, the worker can disassemble the entire moving blade 22 from the mounting plate 26; the operation is simple and the maintenance cost is low.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
