Description

Technical Field

[0001] This utility model relates to the field of rubber hose production technology, specifically to an ultra-low temperature hydrogenated nitrile rubber hose extrusion molding machine. Background Technology

[0002] Ultra-low temperature hydrogenated nitrile butadiene rubber hose is a special type of rubber hose. Its core material is hydrogenated nitrile butadiene rubber (HNBR). This rubber is hydrogenated to convert the unsaturated double bonds in its molecules into saturated bonds, thus giving it excellent heat resistance, oil resistance, and low temperature resistance. Ultra-low temperature hydrogenated nitrile butadiene rubber hose can still maintain excellent physical and mechanical properties in extreme low temperature environments, making it suitable for applications requiring high strength and durability.

[0003] During the extrusion molding of nitrile rubber hoses, dust and other impurities easily adhere to the surface of the rubber compound. If this dust enters the extrusion molding machine along with the rubber compound, it will cause abnormal wear of mechanical parts, reducing the precision and service life of the equipment. Secondly, when placing the rubber compound before extrusion, it is usually placed directly on the ground or in a basket. This method easily causes a large amount of dust to adhere to the rubber compound, further affecting the normal operation of the equipment and the quality of the hose. Utility Model Content

[0020] 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.

[0021] Example: Figure 1-7 As shown, this utility model provides an ultra-low temperature hydrogenated nitrile rubber hose extrusion molding machine, including a molding machine body 1 and a cleaning mechanism 2. A dustproof mechanism 3 is provided on the side of the cleaning mechanism 2 away from the molding machine body 1.

[0022] The cleaning mechanism 2 includes two mounting plates 21. Each mounting plate 21 has a placement plate 22 at its inner end. A sponge 23 is placed on the side of each placement plate 22 away from the mounting plate 21. A worm gear 24 is located at the end of each mounting plate 21 away from the placement plate 22. A worm wheel 25 is meshed with the outside of the worm gear 24. A screw 26 is fixedly mounted in the middle of the worm wheel 25. A moving block 27 is threadedly connected to the outside of the screw 26. The moving block 27 is fixedly connected to the mounting plate 21. A support plate 28 is rotatably sleeved on the outside of the screw 26. The worm gear 24 is fixedly connected to the support plate 28 via a rotating seat. The worm gear 24 is rotatably connected to the support plate 28, and support frames 20 are fixedly installed at both ends of the support plate 28. The side of the placement plate 22 away from the mounting plate 21 is provided with a quick-release mechanism 4. The worm gear 24 and worm wheel 25 are equipped with protective covers, which are fixedly connected to the worm gear 24. The worm gear 24 rotates through the rotating wheel. By setting the cleaning mechanism 2, the sponge 23 cleans the surface of the nitrile rubber tubing material, preventing dust from entering the extrusion molding machine with the rubber material, which would cause abnormal wear of mechanical parts and improve the accuracy and service life of the equipment. The adjustment of the screw 26 allows the sponge 23 above to contact the surface of the rubber material.

[0023] The dustproof mechanism 3 includes a dustproof box 31, which is equipped with a dustproof cover 33. One end of the dustproof cover 33 is fixedly connected to the dustproof box 31, and the other end of the dustproof cover 33 is fixedly installed with a fixing plate 34. Two symmetrically distributed fixing seats 35 are fixedly installed on the end of the dustproof box 31 near the fixing plate 34. The middle of the fixing seat 35 is threaded with a screw rod 36, which is threadedly connected to the fixing plate 34. The screw rod 36 rotates through a plum blossom-shaped rotating wheel, and the fixing plate 34 is pulled by a U-shaped handle. The dustproof cover 33 is retractable. By setting up the dustproof mechanism 3 and cooperating between the dustproof box 31 and the dustproof cover 33, the rubber material before the nitrile rubber tube is extruded is placed, avoiding the rubber material from being placed directly on the ground and adhering to too much dust, thus improving the cleanliness of the rubber material surface.

[0024] Two symmetrically distributed limiting rods 29 are fixedly installed on the side of the mounting plate 21 near the moving block 27. The limiting rods 29 are slidably connected to the support plate 28. By setting the limiting rods 29, the mounting plate 21 is limited to prevent the mounting plate 21 and the moving block 27 from rotating with the screw 26, which would affect the movement of the mounting plate 21.

[0025] The quick-release mechanism 4 includes two symmetrically distributed clamping plates 41. Each clamping plate 41 has two symmetrically distributed T-shaped blocks 42 fixedly installed on the side near the mounting plate 21. A fixing block 43 is slidably sleeved on the outside of the T-shaped block 42. The fixing block 43 is fixed at the edge of the placement plate 22. Two symmetrically distributed fixing components 5 are provided on both sides of the placement plate 22. The fixing components 5 are on the same side as the fixing blocks 43.

[0026] The fixing component 5 includes a fixing block 51, which is fixedly connected to the placement plate 22. The interior of the fixing block 51 is a cavity, and a spring 52 is fixedly installed on the inner wall of the fixing block 51. A moving rod 53 is provided on the inner wall of the spring 52. An insertion rod 54 is fixedly installed at the end of the moving rod 53 near the T-shaped block 42. The insertion rod 54 is fixedly connected to the spring 52. The insertion rod 54, the moving rod 53 and the fixing block 51 are slidably connected. A handle is rotatably connected at the end of the moving rod 53 away from the insertion rod 54. A slot 1 for cooperating with the insertion rod 54 is opened through the middle of the T-shaped block 42. By setting the quick-release mechanism 4 and the fixing component 5 to cooperate, the pressing plate 41 is pressed against the sponge 23, so that the insertion rod 54 in the fixing component 5 is inserted into the corresponding slot 1, thereby fixing the sponge 23 on the placement plate 22. The operation is simple and convenient for disassembly and replacement.

[0027] Two symmetrically distributed trapezoidal blocks 6 are fixedly installed at the end of the placement plate 22 away from the sponge 23. The end of the mounting plate 21 near the placement plate 22 has a trapezoidal groove 61 that cooperates with the trapezoidal blocks 6. By setting the trapezoidal blocks 6, the trapezoidal blocks 6 are inserted into the trapezoidal groove 61, thereby fixing the placement plate 22 and the mounting plate 21 in motion. The operation is simple and convenient for installation and disassembly.

[0028] A connecting block 62 is fixedly installed at one end of the trapezoidal block 6. A fixing component 63 is provided on the side of the mounting plate 21 near the connecting block 62. The fixing component 63 has the same structure as the fixing component 5. The fixing block 51 is fixedly connected to the mounting plate 21. A slot 2 is provided through the middle of the connecting block 62. By setting the fixing component 63, the insertion rod 54 is inserted into the corresponding slot 2, thereby reinforcing the mounting plate 21 and the placement plate 22 and improving stability.

[0029] Two symmetrically distributed crossbars 7 are fixedly installed at the top of the dust box 31, and locking blocks 71 are fixedly installed at both ends of the fixing plate 34. The locking blocks 71 are slidably connected to the crossbars 7. By setting the locking blocks 71, the dust cover 33 is more stable when it is retracted.

[0030] Rollers 8 are rotatably mounted on both the left and right sides of the support frame 20 via fixed blocks. The top wall of the right roller 8 is flush with the top surface of the sponge 23 below. Limiting blocks 81 are fixedly installed at both ends of the roller 8. By setting the roller 8, the rubber material can be kept as horizontal as possible during cleaning to avoid tilting and affecting the cleaning of the rubber material. At the same time, the setting of the limiting blocks 81 limits the rubber material on the roller 8 to prevent the rubber material from moving and affecting the rubber material being put into the extrusion molding machine.

[0031] Working principle: In actual use, the nitrile rubber tubing is placed in the dust box 31, and one end of the tubing is led out from the slot at the top of the dust box 31 and mounted on the right roller 8, so that the bottom surface of the tubing contacts the sponge 23 below. Then, the rotating wheel connected to the upper worm gear 24 is rotated, so that the worm gear 24 drives the worm wheel 25 to rotate. The rotation of the worm wheel 25 drives the screw 26 to rotate in the support plate 28. Due to the limitation of the upper mounting plate 21 by the limiting rod 29, when the screw 26 rotates, it drives the upper moving block 27, the mounting plate 21, the placement plate 22 and the sponge 23 on the placement plate 22 to move down, so that the sponge 23 contacts the top surface of the tubing.

[0032] After adjustment, continue to pull the rubber material forward so that it is mounted on the left rotating roller 8. Then pull the U-shaped handle on the fixing plate 34 to move the dust cover 33 toward the fixing seat 35. During this process, the locking block 71 slides along the cross frame 7. When the fixing plate 34 moves to the limit position, turn the plum blossom handle to drive the screw 36 to rotate and lock into the fixing seat 35, thereby completing the fixing of the dust cover 33 and covering the dust box 31 to prevent dust in the air from adsorbing onto the surface of the rubber material.

[0033] After the dust box 31 is closed, the rubber material is put into the feed port of the molding machine body 1. The rubber material is pushed forward by the rotation of the screw in the barrel and melted and plasticized under high temperature and pressure. As the screw continues to rotate, the molten rubber is evenly squeezed to the die head. Through the forming action of the mold, a rubber tube with a specific shape and size is finally produced.

[0034] When it is necessary to remove the placement plate 22 and sponge 23 from the mounting plate 21, firstly, by rotating the worm gear 24, the worm wheel 25 and the screw 26 are driven to rotate, so that the sponge 23 moves towards the corresponding support plate 28. Then, the handle in the fixing component 2 63 is rotated in sequence. By using the sliding of the inclined surface of the handle on the fixing block 2 51, the moving rod 53 is driven to slide in the fixing block 2 51. The spring 52 contracts, so that the insertion rod 54 slides in the fixing block 2 51 and disengages from the slot 2 opened on the connecting block 62, thereby releasing the fixed connection between the placement plate 22 and the mounting plate 21. Then, the placement plate 22 is pulled outward, so that the trapezoidal block 6 slides along the trapezoidal groove 61, so that the quick-release mechanism 4, fixing component 1 5 and sponge 23 on the placement plate 22 can be taken out. Then, the quick-release mechanism 4, fixing component 1 5 and the new sponge 23 are reinstalled on the placement plate 21. During installation, the trapezoidal block 6 needs to be inserted into the trapezoidal groove 61. Then, the fixing component 2 63 is operated in reverse.

[0035] Then, when removing the sponge 23 from the mounting plate 22, the operation method is the same as that of the fixing component 2 63. Operate the fixing component 1 5 to move the insert 54 away from the slot 1, and then pull the clamping plate 41 upward to remove the sponge 23.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
