Technical Field

[0001] The utility model relates to the field of rubber processing, in particular to an environmentally friendly rubber production and processing rubber cutting machine. Background Art

[0002] Rubber processing is the process of making rubber into rubber products. The basic process of processing various rubber products includes plasticizing, mixing, calendering or extrusion (i.e. extrusion), molding and vulcanization. Each process has different requirements for the product and is combined with several auxiliary operations. In the production process of rubber products, a rubber cutter is needed to cut the rubber into strips or sheets.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 5 As shown, this embodiment provides an environmentally friendly rubber production and processing rubber cutting machine, including a base plate 1, a bracket 2 is fixedly connected above the base plate 1, a hydraulic rod 3 is fixedly installed on the top of the bracket 2, a fixed plate 4 is fixedly connected below the hydraulic rod 3, the hydraulic rod 3 is started to drive the fixed plate 4 to move, a cutting knife 5 is fixedly installed below the fixed plate 4, the fixed plate 4 moves, and the cutting knife 5 moves to cut the rubber, a cleaning mechanism 6 is fixedly connected inside the base plate 1 for removing impurities on the surface of the cutting knife 5, an auxiliary mechanism 7 is rotatably connected inside the cleaning mechanism 6 for cleaning impurities attached to the cleaning mechanism 6 to prevent impurities from remaining on the surface of the cleaning mechanism 6 and affecting the cleaning effect of the cleaning mechanism 6 on the surface of the cutting knife 5 next time, and a driving mechanism 8 for controlling the movement of the auxiliary mechanism 7 is fixedly connected to one side of the bracket 2.

[0023] The improvement of this embodiment is that:

[0024] When the tool cuts rubber, debris and other impurities will be generated and attached to the surface of the tool, which will affect the sharpness of the tool and further affect the normal use of the device. Most rubber cutting machines scrape off the impurities on the surface of the tool by setting a cleaning plate. However, during the long-term use of the cleaning plate, impurities will also adhere to its surface, which will affect the cleaning effect of the subsequent cleaning plate. In addition, rubber sheets and the like need to be fixed during the cutting process, otherwise it will affect the flatness of the cut surface. Therefore, a cleaning mechanism 6 is provided to scrape off the debris attached to the cutting knife 5, and the auxiliary mechanism 7 and the driving mechanism 8 are used to scrape off the impurities attached to the surface of the cleaning mechanism 6 to prevent impurities from remaining on the surface of the cleaning mechanism 6 and affecting the cleaning effect of the cleaning mechanism 6 on the surface of the cutting knife 5 next time, thereby improving the use effect of the device.

[0025] Considering the need to scrape off impurities attached to the surface of the cutting blade 5, the structure of the cleaning mechanism 6 is further disclosed, such as Figure 5 As shown, the cleaning mechanism 6 includes a mounting box 61 fixedly connected to the inside of the bottom plate 1, and two scrapers 62 are rotatably connected inside the mounting box 61, and the two scrapers 62 are arranged in a V shape, and through holes are opened on the surface of the scrapers 62. The cutting knife 5 continues to move downward and passes through the two scrapers 62. Since the spacing between the two scrapers 62 is smaller than the size of the cutting knife 5, when the cutting knife 5 moves downward, the scrapers 62 can scrape off the impurities attached to the surface of the cutting knife 5. One side of the two scrapers 62 is fixedly connected to a telescopic rod 63, and the first telescopic rod 63 is fixedly connected to the first telescopic rod 63. The side of the telescopic rod 63 away from the scraper 62 is rotatably connected to the two sides of the inner wall of the installation box 61 respectively. The outer wall of the No. 1 telescopic rod 63 is sleeved with a No. 1 return spring 64. The downward movement of the cutting knife 5 will squeeze the scraper 62, thereby squeezing the No. 1 telescopic rod 63 to compress, and then drive the No. 1 return spring 64 to deform. After the subsequent cutting knife 5 is moved out of the scraper 62, the scraper 62 is reset and moved under the force of the No. 1 return spring 64 to restore the deformation, so that the No. 1 return spring 64 allows the scraper 62 to better fit the cutting end of the cutting knife 5.

[0026] Considering the need to scrape off impurities adhering to the surface of the scraper 62, the structure of the auxiliary mechanism 7 is further disclosed, such as Figure 4 and Figure 5 As shown, the auxiliary mechanism 7 includes a screw rod 71 rotatably connected to the inner wall of the installation box 61, and one side of the screw rod 71 passes through the rear wall of the installation box 61, and a slider 72 is screwed to the outer wall of the screw rod 71. The screw rod 71 rotates to drive the slider 72 to move linearly on the screw rod 71. Scraper rods 73 are fixedly connected to both sides of the slider 72, and the two scraper rods 73 are located between the two scrapers 62. The movement of the slider 72 drives the scraper rod 73 to move, and further scrapes off the impurities remaining on the surface of the scraper 62 to avoid impurities remaining on the surface of the scraper 62 and affecting the cleaning effect of the scraper 62 on the surface of the cutting knife 5 next time.

[0027] Considering the need to drive the auxiliary mechanism 7 to move, the structure of the driving mechanism 8 is further disclosed, such as Figure 3 and Figure 4 As shown, the driving mechanism 8 includes a connecting rod 81 fixedly connected to one side of the fixed plate 4. The fixed plate 4 moves upward, driving the connecting rod 81 to move upward. A spur plate 82 is slidably connected to one side of the bracket 2, and one side of the spur plate 82 is fixedly connected to the connecting rod 81. The connecting rod 81 moves upward, driving the spur plate 82 to move upward. A rotating rod 83 is rotatably connected to the side of the bracket 2 close to the spur plate 82, and one side of the rotating rod 83 passes through the rear side of the bracket 2. A gear 84 is fixedly connected to the side of the rotating rod 83 close to the fixed plate 4, and the gear 84 is meshed with the spur plate 82. The spur plate 82 moves upward, driving the gear 84 to mesh and transmit, thereby driving the rotating rod 83 to rotate. A belt 85 is sleeved on one side of the rotating rod 83 that passes through the bracket 2, and the side of the belt 85 away from the rotating rod 83 is sleeved on the side of the screw rod 71 that passes through the installation box 61. The rotating rod 83 rotates, and cooperates with the belt 85 to drive the scraper rod 73 in the auxiliary mechanism 7 to move.

[0028] Taking into account the need to fix the rubber, the left and right sides of the fixed plate 4 are fixedly connected with mounting plates 9. When the fixed plate 4 moves downward, the mounting plate 9 is driven to move downward. A No. 2 telescopic rod 10 is fixedly connected below the mounting plate 9. The mounting plate 9 moves downward, driving the No. 2 telescopic rod 10 to move downward. A limit plate 12 is fixedly connected below the No. 2 telescopic rod 10. The No. 2 telescopic rod 10 moves downward, driving the limit plate 12 to move downward, thereby fixing the rubber on the surface of the conveyor 13 and improving the stability of the rubber during cutting. The outer wall of the No. 2 telescopic rod 10 is sleeved with a No. 2 return spring 11. At this time, the No. 2 return spring 11 is compressed and deformed to generate a reaction force, which can improve the stability of the device for fixing the rubber.

[0029] Taking into account the need to convey the rubber for cutting, two conveyors 13 are rotatably connected inside the base plate 1, and the two conveyors 13 are symmetrically arranged on the left and right sides of the base plate 1 relative to the hydraulic rod 3. The conveyor 13 is composed of a conveyor roller, a conveyor belt and a drive motor. Starting the drive motor drives the conveyor roller to rotate, thereby driving the conveyor belt to transmit the rubber placed on the conveyor belt.

[0030] In order to prevent scraped impurities from falling onto the surface of the screw rod 71 , a protective box 14 is fixedly connected to the inner wall of the mounting box 61 , and the protective box 14 is located outside the screw rod 71 , which effectively prevents scraped impurities from falling onto the outer wall of the screw rod 71 and causing damage to the screw rod 71 .

[0031] When the utility model environmentally friendly rubber production and processing rubber cutting machine is used, the conveyor 13 is first started to transport the rubber to the bottom of the cutting knife 5, and then the conveyor 13 is closed, and the hydraulic rod 3 is started to drive the fixed plate 4 to move downward, thereby driving the cutting knife 5 to move downward to cut the rubber. After cutting, the cutting knife 5 continues to move downward and passes through the two scrapers 62. Since the spacing between the two scrapers 62 is smaller than the size of the cutting knife 5, when the cutting knife 5 moves downward, the scraper 62 can scrape off the impurities attached to the surface of the cutting knife 5, and the scraped impurities can fall into the bottom of the installation box 61 through the through holes on the surface of the scraper 62;

[0032] Then start the hydraulic rod 3 to drive the fixed plate 4 and the cutting knife 5 to move upward. The fixed plate 4 moves upward, driving the connecting rod 81 to move upward, thereby driving the spur plate 82 to move upward, and then driving the gear 84 to engage the transmission. The gear 84 rotates, cooperates with the belt 85, drives the screw rod 71 to rotate, thereby driving the slider 72 to move linearly on the screw rod 71, and then drives the scraper rod 73 to move, and further scrapes off the impurities remaining on the surface of the scraper 62 to prevent impurities from remaining on the surface of the scraper 62 and affecting the scraper 62 The cleaning effect of the next time on the surface of the cutting knife 5, when the fixed plate 4 moves downward, drives the mounting plate 9 to move downward, thereby driving the No. 2 telescopic rod 10 to move downward, and then drives the limit plate 12 to move downward, fixes the rubber on the surface of the conveyor 13, and improves the stability of the rubber during cutting.
