Description

Technical Field

[0001] This utility model relates to edge trimming equipment, specifically polyurethane film edge trimming equipment, and belongs to the field of polyurethane film edge trimming technology. Background Technology

[0002] Polyurethane film is also known as PU film. PU film has advantages such as good elasticity and high strength. It is an environmentally friendly material. Polyurethane film is non-toxic and harmless and does not cause any harm to human skin. Therefore, polyurethane film is widely used in clothing fabrics, medical and health care, leather and other fields. During the production and processing of polyurethane film, it needs to be heat-sealed and edge-finished by a heat-sealing slitting machine.

[0003] However, when heat-sealing the edges of polyurethane film, the film itself is elastic. When it is heat-cut, the edges expand when heated and shrink due to internal stress after cooling. This may cause the edges to curl inward or outward, forming a wavy unevenness. Uneven edges of the polyurethane film may lead to poor heat sealing, which can easily cause problems such as leakage and air leakage. Utility Model Content

[0004] The purpose of this invention is to provide a polyurethane film edge-sealing processing device to solve the above problems. After the polyurethane film is cut and sealed by a hot cutter, it can be transported to a position close to the hot press roller by a film support rod. When the hot press roller contacts the surface of the polyurethane film, it can squeeze the polyurethane film. The smooth surface of the hot press roller can flatten the uneven edges of the polyurethane film after hot cutting, so as to form a uniform edge-sealing thickness and prevent problems such as leakage of liquid and air.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a polyurethane film edge-trimming processing equipment, including a slitting machine body, a fixed rod fixedly connected to the slitting machine body, a film support rod and a film guide rod fixedly installed on the slitting machine body, a plurality of collars installed on the fixed rods through a fixing mechanism, an edge-trimming mechanism fixedly installed on the collars, the edge-trimming mechanism including a hot cutting knife and a fixing frame, a fixing frame fixedly connected to the side wall of the collars, a hot cutting knife fixedly installed inside the fixing frame, a hydraulic rod fixedly installed on the side of the collars away from the fixing frame, an installation block fixedly connected to the telescopic end of the hydraulic rod, a connecting shaft rotatably connected to the installation block, and a hot pressure roller fixedly installed on the connecting shaft.

[0006] Preferably, the fixing frame is inclined, and the hot cutting blade is located at the top of a film support rod.

[0007] Preferably, the hot press roller is rotatably connected to the mounting block, the hydraulic rod is inclined, and the hot press roller is located at the top of another membrane support rod.

[0008] Preferably, the two membrane support rods and membrane guide rods are symmetrically arranged about the fixed rod, and the diameter of the fixed rod is larger than the diameter of the membrane support rod and the membrane guide rod.

[0009] Preferably, several of the collars are equidistantly installed on the side wall of the fixing rod, and the diameter of the collars is larger than the diameter of the fixing rod.

[0010] Preferably, the fixing mechanism includes a rotating block and a lead screw. The lead screw is rotatably mounted on the collar, the rotating block is fixedly connected to the lead screw, a sleeve is threadedly connected to the lead screw, and a stop block is fixedly connected to the sleeve.

[0011] Preferably, the sleeve and the collar are slidably connected, and the diameter of the sleeve is larger than the diameter of the lead screw.

[0012] Preferably, the fixing mechanism further includes a gasket, and the gasket is fixedly connected to the abutment block, the gasket abutting against the side wall of the fixing rod.

[0013] Preferably, the abutment and the collar are slidably connected, and the part of the abutment that contacts the gasket has an arc-shaped structure.

[0014] The beneficial effects of this invention are as follows: When cutting the polyurethane film, the polyurethane film can be conveyed to the guide rod and the support rod by the conveying roller. Since the guide rod is inclined relative to the support rod, it can be spread out during the cutting of the polyurethane film, so that the polyurethane film is in a flat state. During the movement of the polyurethane film, the hot cutting knife installed on the fixed frame cuts and seals the polyurethane film. When the polyurethane film moves to the part close to the hot pressure roller, the control switch of the hydraulic rod is turned on, so that its telescopic end drives the mounting block to move down, thereby making the hot pressure roller installed on the connecting shaft contact the surface of the polyurethane film. The hot pressure roller can squeeze the polyurethane film. Since the smooth surface of the hot pressure roller can flatten the uneven edges of the polyurethane film after hot cutting, it is easier to form a uniform sealing thickness of the polyurethane film and prevent problems such as leakage and air leakage.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 As shown, the polyurethane film edge-sealing equipment includes a slitting machine body 1. A fixing rod 2 is fixedly connected to the slitting machine body 1. A film support rod 3 and a film guide rod 4 are fixedly installed on the slitting machine body 1. Several collars 6 are installed on the fixing rod 2 through a fixing mechanism 7. An edge-sealing mechanism 5 is fixedly installed on the collars 6. The edge-sealing mechanism 5 includes a hot cutting blade 501 and a fixing frame 502. The fixing frame 502 is fixedly connected to the side wall of the collars 6. The fixing frame 502 is inclined. The hot cutting blade 501 is fixedly installed inside the fixing frame 502. The hot cutting blade 501 on the fixing frame 502 cuts and seals the polyurethane film. The hot cutting blade 501 is located at the top of a film support rod 3. The side of the collar 6 facing away from the fixing frame 502 is fixed. A hydraulic rod 503 is installed at an angle. The telescopic end of the hydraulic rod 503 is fixedly connected to a mounting block 504. A connecting shaft 505 is rotatably connected to the mounting block 504. A hot pressure roller 506 is fixedly installed on the connecting shaft 505. The telescopic end of the hydraulic rod 503 drives the mounting block 504 to move downward, so that the hot pressure roller 506 contacts the surface of the polyurethane film. The hot pressure roller 506 can squeeze the polyurethane film. Since the smooth surface of the hot pressure roller 506 can flatten the uneven edges of the polyurethane film after hot cutting, it is easier to form a uniform sealing thickness of the polyurethane film and prevent problems such as leakage and air leakage. The hot pressure roller 506 is rotatably connected to the mounting block 504, and the hot pressure roller 506 is located at the top of another film support rod 3.

[0024] As a technical optimization of this utility model, the two film-supporting rods 3 and the film-guide rods 4 are symmetrically arranged about the fixed rod 2. The diameter of the fixed rod 2 is larger than the diameter of the film-supporting rods 3 and the film-guide rods 4. When the polyurethane film is cut by the heat-sealing slitting machine, the polyurethane film can be conveyed to the film-guide rods 4 and the film-supporting rods 3 by the conveying rollers. Since the film-guide rods 4 are inclined about the film-supporting rods 3, they can be stretched open when the polyurethane film is cut, so that the polyurethane film is in a flat state, which helps to prevent errors in the cutting position of the polyurethane film.

[0025] As a technical optimization of this utility model, several of the collars 6 are equidistantly installed on the side wall of the fixing rod 2, and the diameter of the collars 6 is larger than the diameter of the fixing rod 2.

[0026] As a technical optimization of this utility model, the fixing mechanism 7 includes a rotating block 701 and a lead screw 702. The lead screw 702 is rotatably mounted on the collar 6, and the rotating block 701 is fixedly connected to the lead screw 702. A sleeve 704 is threadedly connected to the lead screw 702, and a stop block 705 is fixedly connected to the sleeve 704. The sleeve 704 is slidably connected to the collar 6. The rotating block 701 drives the lead screw 702 to rotate within the collar 6. Since the stop block 705 is limited by the inner wall of the collar 6, it is driven by the lead screw 702. Under power, the sleeve rod 704 can drive the abutment block 705 to slide within the collar 6; and the diameter of the sleeve rod 704 is larger than the diameter of the lead screw 702. A washer 703 is fixedly connected to the abutment block 705. The washer 703 abuts against the side wall of the fixed rod 2. The abutment block 705 and the collar 6 are slidably connected. The part of the abutment block 705 that contacts the washer 703 is set with an arc surface structure. When the washer 703 contacts the side wall of the fixed rod 2, the collar 6 can be installed on the side wall of the fixed rod 2, thereby facilitating the adjustment of the position of the collar 6.

[0027] In use, this invention firstly involves the polyurethane film being cut using a heat-sealing slitting machine. The polyurethane film is conveyed by a conveyor roller to the guide rod 4 and the support rod 3. Since the guide rod 4 is inclined relative to the support rod 3, it can be spread out during cutting, ensuring the polyurethane film is flat and preventing errors in the cutting position. When the polyurethane film is wrapped around the two support rods 3, the two support rods 3 can spread the polyurethane film, bringing it into contact with the sidewalls of the support rods 3. A rotating block 701 fixed to the end of the rotating screw 702 drives the screw 702 to rotate within the collar 6. A sleeve rod 704 is threaded onto the screw 702, and a stop block 705 is fixed to the end of the sleeve rod 704. The stop block 705 is limited by the inner wall of the collar 6. Under the driving force of the screw 702, the sleeve rod 704... 4 can drive the abutment 705 to slide inside the collar 6. When the gasket 703 installed at the bottom of the abutment 705 contacts the side wall of the fixing rod 2, the collar 6 can be installed on the side wall of the fixing rod 2, which facilitates the adjustment of the position of the collar 6. The side wall of the collar 6 is equipped with a fixing frame 502. The hot cutting blade 501 installed on the fixing frame 502 cuts and seals the polyurethane film. When the polyurethane film moves close to the hot pressure roller 506, the control switch of the hydraulic rod 503 is turned on, so that its telescopic end drives the mounting block 504 to move down, which in turn makes the hot pressure roller 506 installed on the connecting shaft 505 contact the surface of the polyurethane film. The hot pressure roller 506 can squeeze the polyurethane film. Since the smooth surface of the hot pressure roller 506 can flatten the uneven edges of the polyurethane film after hot cutting, it is easier to form a uniform sealing thickness of the polyurethane film and prevent problems such as leakage and air leakage.
