Description

Technical Field

[0001] The invention relates to the technical field related to rubber sealing gasket cutting, and in particular to a cutting device for preparing rubber sealing gaskets. Background Art

[0002] Rubber gaskets are resistant to oil, acid and alkali, cold and heat, and aging. They can be directly cut into sealing gaskets of various shapes and are widely used in medicine, electronics, chemicals, antistatic materials, flame retardant materials, food and other industries. Rubber gaskets are thin-sheet rubber products that seal between two stationary surfaces of metal flanges or other connecting parts. They are collectively called rubber gaskets. They can be manufactured by molding or punched by vulcanized rubber sheets. They can be widely used in various mechanical equipment to play the role of lining, sealing, and buffering. Commonly used rubber gaskets include: rubber flat washers, rubber O-rings, plastic flat washers, polytetrafluoroethylene-wrapped washers, asbestos rubber washers, metal flat washers, and spiral wound washers. During the preparation of rubber gaskets, the rubber roller needs to be guided out and cut into blocks in order to facilitate the punching and cutting of the rubber sheets. When cutting the rubber gaskets, two workers usually lay the rubber sheets wound on the hollow winding roller on the shearing table, which is time-consuming and labor-intensive, and greatly increases the labor intensity of the workers. Simultaneously, when cutting the rubber gaskets, rubber crumbs are often attached to the shearing knife. A large amount of rubber crumbs adsorbed on the blade surface will affect the cutting effect of the shearing knife, and the workers need to clean the blade surface of the shearing knife regularly, which is time-consuming and labor-intensive, and increases the labor intensity of the workers.

[0020] The following is a further description of the method and principle of using the technical solution in this specific implementation method in conjunction with the accompanying drawings: When the pressing and cutting assembly is in the initial position, the first baffle plate 23 is connected to the first fixed plate 14; the staff sets the hollow winding roller with the rubber gasket wound on the first transmission shaft 27, and the staff can pass the stud bolts through the winding roller and the shaft hole 28 at the same time, and then tighten the nuts at both ends of the stud bolts to complete the fixed connection between the winding roller and the first transmission shaft 27; At the same time, the staff leads out the rubber gasket on the winding roller, so that the rubber gasket passes through the bottom surface of the pressing plate 4 and is pulled to the first fixing plate 14; the staff pulls up the first fixing plate 14 through the first handle 15, and the first fixing plate 14 drives the first connecting shaft 16 and the first limiting ring 18 to move upward, thereby pressing the first spring 17, and at the same time, the staff places the end of the rubber gasket at the bottom of the first fixing plate 14, and the staff releases the first handle 15, and the reaction force of the first spring 17 will drive the first fixing plate 14 to reset, thereby completing the fixed connection of the end of the rubber gasket; At this time, the staff starts the motor 22, and the power output shaft of the motor 22 rotates to drive a first screw shaft 2 axially connected to it to rotate, and the rotation of the first screw shaft 2 drives a first pulley 20 concentric with it to rotate, and the rotation of the first pulley 20 drives another first pulley 20 to rotate through the first transmission belt 21, and the two first pulleys 20 rotate synchronously, and then the two first screw shafts 2 concentric with them rotate synchronously; the synchronous rotation of the two first screw shafts 2 drives the first baffle plate 23 screwed with them to move, and the movement of the first baffle plate 23 drives the first connecting plate 26 to move at the same time, and the synchronous movement of the first connecting plate 26 drives The first gear 29 meshing with the rack plate 12 rotates, and the first gear 29 rotates to drive the first transmission shaft 27 concentric therewith to rotate, and the first transmission shaft 27 rotates to drive the winding roller fixedly connected thereto to rotate, thereby releasing the rubber gasket wound on the winding roller, and then as the first baffle plate 23 moves to the other side of the workbench 1, the staff can cut the rubber gasket with a cutting knife, thereby separating the rubber gasket on the winding roller from the rubber gasket on the workbench 1, and at the same time, the staff can tighten the rubber gasket on the winding roller with a strap or tape to prevent the rubber gasket on the winding roller from becoming loose; At this time, the rubber gasket on the workbench 1 has been laid, and the staff starts the motor 22 again to reverse the power output shaft of the motor 22, and then drives the first baffle 23 to move in the opposite direction through the above steps. When the position of the shearing knife 33 moves to a suitable distance, the staff turns off the motor 22; the staff starts the cylinder 35, the piston shaft end of the cylinder 35 is pushed out and then moves down through the push rod 36 connected with it, thereby driving the first driving plate 3 downward; the first driving plate 3 moves downward and drives the driving block 31 downward. At this time, the pressing plate 4 first connects with the rubber gasket on the top of the workbench 1, and then preliminarily fixes the rubber gasket to ensure that the rubber gasket will not shift during the cutting process; The first driving plate 3 is synchronously continuously moved downward, and the second connecting shaft 40 can press the second spring 34 through the second limiting ring 41, thereby compensating the stroke of the first driving plate 3; synchronously, as the first driving plate 3 is continuously moved downward, the shearing knife 33 is continuously moved downward, and the shearing knife 33 moves downward, so that the blade of the shearing knife 33 passes through the two chip removing plates 46, so that the two chip removing plates 46 move to both sides, and then drive the third limiting ring 44 to press the third spring 43 through the third connecting shaft 45, and the synchronous shearing knife 33 moves downward to cut the rubber gasket machine on the workbench 1. After the synchronous rubber gasket cutting is completed, the piston shaft end of the cylinder 35 retracts, and at this time, the shearing knife 33 is retracted between the two chip removing plates 46. Since the cut surface 47 of the chip removing plate 46 is always in contact with the blade surface of the shearing knife 33, when the shearing knife 33 retracts, the tip cut surface 47 of the chip removing plate 46 can scrape off the rubber debris adsorbed on the shearing knife 33, thereby ensuring the cleanliness of the blade surface of the shearing knife 33; Then the staff can repeat the above steps to cut the rubber gasket on the workbench 1 for multiple times, so as to cut the long strip rubber gasket into multiple rectangular rubber gaskets of uniform size, so as to facilitate the subsequent stamping of rubber sealing gaskets of various shapes; When the rubber gaskets on the workbench 1 are cut synchronously, the pressing and cutting assembly is reconnected to the first fixed plate 14, and the staff can repeat the above steps to continue cutting the rubber gaskets wound on the winding roller; The initial position of the synchronized shearing blades 33 is above the two chip removal plates 46 .

[0021] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
