Description

Technical Field

[0001] The invention relates to the technical field of rubber processing, in particular to a device for cutting rubber strips after special rubber is extruded. Background Art

[0002] As a highly elastic polymer material with reversible deformation, rubber is highly elastic at room temperature and can produce large deformations under small external forces, but can return to its original shape after the external force is removed. Rubber products made from natural and synthetic rubber, especially rubber strips, are widely used in various fields such as construction, automobiles, machinery, and electronics due to their sealing, noise reduction, and protective functions. The processing technology of rubber strips usually includes the steps of raw material preparation, mixing, extrusion, vulcanization, cooling and cutting. Among them, the cutting step is to cut the continuous rubber strips after extrusion into specific lengths to meet the needs of subsequent use. However, there are many problems with the rubber strip cutting equipment in the prior art: due to the soft texture of the rubber strips, it is difficult to keep them straight during transportation, resulting in inconsistent lengths of the cut rubber strips. It is often necessary to perform a second cutting to obtain products of standard length, which is not only time-consuming and labor-intensive, but also reduces production efficiency; in addition, when the tool is cutting the rubber strips, rubber molecules or particles are likely to remain on the surface of the tool. Long-term accumulation will cause the tool to become blunt, which in turn affects the cutting quality of the rubber strips and makes the end face of the rubber strips uneven. Therefore, there is an urgent need for a rubber strip cutting device that has a fixed-length cutting function and can guarantee cutting quality. Summary of the Invention

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1-8 The present invention provides a technical solution: a cutting device for special rubber strips after extrusion, comprising a mounting base 1 and a controller 2. The left side of the mounting base 1 is installed with the conveyor line, the controller 2 is installed on the upper surface of the mounting base 1, and two front and rear opposing blocking rods 3 are installed on the right side of the upper surface of the mounting base 1 to block the rubber strips. A conveying and measuring mechanism 4 is installed on the lower surface of the mounting base 1, and the conveying and measuring mechanism 4 can accurately measure the cutting length of the rubber strips. A cutting mechanism 5 is installed on the right end of the rear side of the mounting base 1 to cut the rubber strips.

[0021] As a preferred solution, further, the conveying and measuring mechanism 4 includes a casing 41 installed on the lower surface of the mounting seat 1, and two first guide rods 42 are installed at the top opening of the casing 41 along the front and rear directions. The front and rear ends of the outer wall of the first guide rod 42 are respectively sleeved with a slide 43 and a spring 44, and the slide 43 is pushed forward under the elastic force of the spring 44. A conveying component 45 is installed on the rear side of the upper surface of the casing 41, and the rubber strip is moved from left to right through the conveying component 45. A travel switch 46 electrically connected to the controller 2 is embedded in the front end of the lower surface of the slide 43, and a first rotating shaft 47 capable of rotating around its own axis is installed in the middle of the lower surface of the slide 43 through a bearing. The outer wall of the first rotating shaft 47 is provided with a length unit, and the length unit displays the arc plate 4 11 moves outward or inward to form a rotating circumference, which is convenient for adjusting the cutting length of the rubber strip. An adjustment component 48 is installed on the outer wall of the first rotating shaft 47. A number of telescopic rods 49 are installed on the top of the outer wall of the first rotating shaft 47 at equal intervals along the circumferential direction. A limit block 410 corresponding to the position of the travel switch 46 is installed on the outer side of the top of one of the telescopic rods 49. An arc plate 411 is installed on the outer side of the telescopic rod 49. One side of the outer wall of the arc plate 411 is sleeved with a V-belt 412, and the other side of the V-belt 412 is sleeved with the conveying component 45. The conveying component 45 is linked to the first rotating shaft 47 through the V-belt 412. The bottom of the arc plate 411 is connected to one end of a connecting rod 413 through a pin, and the other end of the connecting rod 413 is connected to the outer wall of the adjusting component 48 through a pin.

[0022] More specifically, when the conveyor assembly 45 is operating to move the rubber strip, the first rotating shaft 47 rotates under the transmission action of the V-belt 412, which in turn drives the telescopic rod 49, the curved plate 411, and the limit block 410 to rotate together. When the limit block 410 rotates and triggers the limit switch 46, the limit switch 46 transmits a signal to the controller 2. Based on this signal, the controller 2 determines that the rubber strip has reached the set cutting length and controls the subsequent cutting mechanism to perform the cutting action. If the cutting length of the rubber strip needs to be adjusted, the position of the curved plate 411 can be changed by adjusting the adjustment assembly 48. Combined with the length unit of the outer wall of the first rotating shaft 47, the cutting length of the rubber strip can be precisely adjusted.

[0023] As a preferred solution, further, the conveying assembly 45 includes a gear box 451 installed at the rear end of the upper surface of the casing 41, and two second rotating shafts 452 are installed at the front and rear ends of the upper surface of the gear box 451 through bearings, and the outer wall of the second rotating shaft 452 is installed with a first gear 453 that meshes with each other, and the lower surface of the gear box 451 is installed with a motor 454 connected to the bottom end of the second rotating shaft 452 through a coupling, and the motor 454 is electrically connected to the controller 2, and a pulley 455 is installed at the bottom end of the outer wall of the second rotating shaft 452 located on the front side, and the V-belt 412 is sleeved on the outer wall of the pulley 455, and a conveying roller 456 is installed on the top of the second rotating shaft 452, and the rubber strip is conveyed by the rotation of the conveying roller 456.

[0024] More specifically, when the motor 454 is started, the second rotating shaft 452 connected to it is driven to rotate through the coupling. Under the transmission of the two mutually meshing first gears 453, the two second rotating shafts 452 rotate in opposite directions, thereby driving the two conveying rollers 456 on the top to rotate in opposite directions synchronously. The friction between the conveying rollers 456 and the rubber strip is used to stably convey the rubber strip from left to right, providing continuous material supply for subsequent length measurement and cutting processes.

[0025] As a preferred solution, further, the adjusting assembly 48 includes a sleeve 481 that is sleeved on the outer wall of the first rotating shaft 47, and the outer wall of the sleeve 481 is connected to the bottom of the connecting rod 413 through a pin shaft, and a plurality of brake pads 482 are circumferentially installed on the bottom of the sleeve 481, and the outer wall of the brake pad 482 is provided with a thread, and the outer wall of the brake pad 482 is screwed with a fastening nut 483, and the outer wall of the brake pad 482 is in the shape of an inclined surface. When the fastening nut 483 moves onto the brake pad 482, the fastening nut 483 can squeeze the brake pad 482 inward, so that the brake pad 482 is pressed tightly against the outer wall of the first rotating shaft 47.

[0026] More specifically, when it is necessary to adjust the cutting length of the rubber strip, the fastening nut 483 is screwed in the opposite direction to move the fastening nut 483 away from the brake pad 482. The extrusion force on the brake pad 482 disappears. At this time, the sleeve 481 can be pushed up and down along the first rotating shaft 47, and the arc plate 411 is driven to move through the connecting rod 413 to change the rotation diameter. After adjusting to the required length, the fastening nut 483 is tightened again to complete the adjustment.

[0027] As a preferred embodiment, further, the cutting mechanism 5 includes a water tank 51 mounted on the right end of the rear side of the mounting base 1, wherein the water tank 51 stores a rubber dissolving agent, a cleaning assembly 52 is mounted on the top of the front inner wall of the water tank 51, and a support plate 53 is mounted on the right side wall of the water tank 51. The outer wall of the support plate 53 is provided with a guide groove 54 along the front and rear directions. The guide groove 54 is horizontally arranged on the outer wall of the support plate 53, and the rear side is tilted downward. The inclined surface of the guide groove 54 allows the cutter 59 to enter the water tank 51, and the horizontal surface of the guide groove 54 allows the cutter 59 to move horizontally for cutting the rubber strip. Cut, a first cylinder 55 electrically connected to the controller 2 is installed at the rear end of the top of the left side wall of the support plate 53, and a push plate 56 is installed at the output end of the first cylinder 55. A lifting rod 57 that can slide up and down is inserted into the inner cavity of the push plate 56. The lifting rod 57 is rectangular in shape to prevent the cutter 59 from rotating. A roller 58 inserted into the inner cavity of the guide groove 54 is installed at the bottom of the right side wall of the lifting rod 57. The height of the lifting rod 57 is controlled by the cooperation of the roller 58 and the guide groove 54. A cutter 59 is installed at the bottom of the lifting rod 57, and the cutter 59 is used to move forward to cut the rubber strip.

[0028] More specifically, the height of the lifting rod 57 is controlled by the rolling engagement of the roller 58 within the guide groove 54. A cutter 59 is mounted at the bottom of the lifting rod 57. When the first cylinder 55 pushes the push plate 56 forward, the lifting rod 57, in conjunction with the roller 58 and the guide groove 54, drives the cutter 59 to rise to a desired height and then move forward horizontally, cutting the rubber strip with the forward movement of the cutter 59. After cutting is complete, the first cylinder 55 drives the push plate 56 back to its original position, and the cutter 59, in conjunction with the roller 58 and the inclined surface of the guide groove 54, descends into the water tank 51 to be cleaned with a rubber dissolving agent.

[0029] As a preferred solution, further, the cleaning component 52 includes a box body 521 installed on the top of the front inner wall of the water tank 51, and second guide rods 522 are installed on both sides of the inner cavity of the box body 521. The left and right sides of the outer wall of the second guide rod 522 are sleeved with a movable plate 523. The center position of the inner cavity of the box body 521 is connected to a second gear 524 through a pin shaft. A rack 525 meshing with the second gear 524 is installed on the top of the movable plate 523. The two racks 525 are respectively located at At the front and rear sides of the second gear 524, when the second gear 524 rotates, the two racks 525 move in opposite directions, thereby causing the two movable plates 523 to move inward or outward at the same time. A second cylinder 526 electrically connected to the controller 2 is installed on the left side of the box body 521. The left movable plate 523 is driven to move left and right by the second cylinder 526. A scraper 527 is installed at the rear end of the movable plate 523. When the scraper 527 contacts the cutter 59, the scraper 527 can scrape off debris on the surface of the cutter 59.

[0030] More specifically, the output end of the second cylinder 526 is connected to the left movable plate 523, which can drive the left movable plate 523 to move left and right. A scraper 527 is installed at the rear end of the movable plate 523. When the cutter 59 completes cutting and moves, the controller 2 controls the second cylinder 526 to move, driving the left movable plate 523 to move right. Under the transmission action of the second gear 524 and the rack 525, the right movable plate 523 moves left synchronously, causing the two scrapers 527 to move inward and contact with the cutter 59. As the cutter 59 moves, the scrapers 527 can scrape off debris on the surface of the cutter 59 to ensure the sharpness of the cutter 59. When cleaning is completed, the second cylinder 526 drives the left movable plate 523 to move left, and the two scrapers 527 move outward accordingly, breaking away from contact with the cutter 59 and waiting for the next cleaning action.

[0031] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0032] Step 1: The second rotating shaft 452 is driven by the motor 454 to rotate. Under the transmission condition of the two first gears 453, the conveying roller 456 rotates in the opposite direction. The conveying roller 456 allows the rubber strip to move from left to right. At the same time, the first rotating shaft 47 can be rotated under the transmission of the pulley 455, the V-belt 412 and the curved plate 411. When the limit block 410 triggers the limit switch 46 during the rotation, the limit switch 46 feeds back an electrical signal to the controller 2. The controller 2 controls the motor 454 to stop, and the first cylinder 55 pushes the push plate 56 forward. The roller 58 rolls in the guide groove 54. The lifting rod 57 rises along the push plate 56 and then moves horizontally forward. The cutter 59 completes the cutting of the rubber strip, realizing the fixed-length cutting of the rubber strip. Step 2: When the cutting length needs to be changed, the fastening nut 483 is screwed away from the brake pad 482 to loosen the brake pad 482, pushing the sleeve 481 up or down, allowing the connecting rod 413 to pull the curved plate 411 outward or inward, and the rotation diameter formed by the curved plate 411 becomes larger or smaller until the length of one rotation of the curved plate 411 is consistent with the cutting length of the rubber strip. The fastening nut 483 is screwed onto the brake pad 482, and the brake pad 482 is pressed against the outer wall of the first rotating shaft 47, completing the adjustment of the rotation diameter of the curved plate 411, and realizing fixed-length cutting of various lengths of rubber strips; Step three, when it is necessary to clean the cutter 59, the rubber solvent in the water tank 51 dissolves the rubber residue left on the surface of the cutter. When the cutter 59 moves to accurately cut the rubber strip, the controller 2 controls the second cylinder 526 to drive the left movable plate 523 to move right. Under the transmission conditions of the rack 525 and the second gear 524, the two movable plates 523 can be moved inward at the same time, allowing the scraper 527 to contact the cutter 59. As the cutter 59 moves, the scraper 527 scrapes off the rubber solvent, thereby cleaning the cutter 59 and allowing the cutter 59 to cut the rubber strip more smoothly.

[0033] The present invention can achieve fixed-length and precise cutting of rubber strips of various specifications. The rubber strips have the same length and do not need secondary cutting, which saves time and labor. The invention has a cutter cleaning function to prevent the cutter from becoming blunt and affecting the cutting quality.

[0034] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
