Description

Technical Field

[0001] The utility model relates to the technical field of rubber and plastic extruders, in particular to a rubber extruder which is easy to load. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a large molecular weight, greater than hundreds of thousands. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is processed from the extraction of colloid from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in various aspects of industry or life, including LED silicone rubber light strips.

[0003] According to the prior art patent number CN 214214671 U, a light strip extruder that is easy to load has solved the problem of inconvenient loading of the extruder through the setting of the loading rack, etc. However, after using it for a period of time, it was found that in order to facilitate the operation of pulling the material strip discharged from the extruder into the cold water tank, an empty space was left between the extruder and the cold water tank. During summer production, due to the hot and humid production environment of the rubber workshop, there are many mosquitoes. Mosquitoes often fly between the extruder and the cold water tank and hit the product material strip being conveyed. At this time, the product material strip is in an uncooled and softened stage, and the surface is sticky. The mosquitoes are stuck to the material strip after hitting it, and then pollute the product.

[0004] Therefore, a rubber extruder that is easy to load is needed to solve the problem in the prior art that during summer production, there are many mosquitoes in the hot and humid production environment of the rubber workshop, and mosquitoes often fly between the extruder and the cold water tank and hit the product belt being conveyed. At this time, the product belt is in an uncooled and softened stage, and the surface is sticky. After hitting the belt, the mosquitoes are stuck to the belt, and then contaminate the product. Utility Model Content

At this time, the product belt is in an uncooled and softened stage, and the surface is sticky. After hitting the belt, the mosquitoes are stuck to the belt, and then cause pollution to the product.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: a rubber extruder that is easy to load, comprising an extruder body and a cold water tank arranged in front of the discharge port of the extruder body, the cold water tank is provided with a through hole corresponding to the discharge port on one side facing the extruder body, and is characterized in that: it also includes a shield long tube arranged between the discharge port and the through hole, and a closing and separating mechanism is arranged below the shield long tube;

[0007] The shield long tube is composed of two semi-ring-shaped bearing bushes arranged opposite to each other, one end of the bearing bush is slidably connected to the side wall of the extruder body, and the other end of the bearing bush is slidably connected to the side wall of the cold water tank;

[0008] The closing and separating mechanism comprises a base arranged below the bearing shell and a double-sided screw rod transversely arranged between the base and the bearing shell, movable blocks are respectively threadedly sleeved on both sides of the rod body of the double-sided screw rod, and the two movable blocks are respectively fixed to the sides of the two bearing shells that are away from each other, and the bottom surface of the movable block is slidably connected to the top surface of the base, and both ends of the double-sided screw rod are rotatably sleeved with fixed plates, and the two fixed plates are respectively vertically fixed to the two sides of the top surface of the base, and a transmission component is arranged on one of the fixed plates;

[0012] Compared with the prior art, the advantages of the utility model are:

[0013] (1) Through the coordinated arrangement of the protective cover long tube and the closing and separating mechanism, when the rubber light strip needs to be produced, the rubber light strip is extruded through the discharge port of the extruder main body and transported to the cold water tank for cooling. Then, the double-sided screw is driven to rotate through the transmission component, and then the two moving blocks are driven. The moving blocks are restricted by the base and can only extend on the top surface of the base to make relative or opposite movements. The relative movement of the two moving blocks closes the two bearings and then covers the rubber light strip.

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0021] Reference Figure 1 , Figure 2 and Figure 3 As shown, a rubber extruder that is easy to load includes an extruder body 1 and a cold water tank 2 arranged in front of a discharge port of the extruder body 1, and a through hole corresponding to the discharge port is opened on one side of the cold water tank 2 facing the extruder body 1;

[0022] Through the arrangement of the extruder body 1 and the cold water tank 2, when it is necessary to produce an adhesive tape, the rubber light strip extruded from the discharge port of the extruder body 1 can be passed through the cold water tank 2, and the rubber light strip can be cooled by the cooling water in the cold water tank 2. The cooled rubber light strip passes through the cold water tank 2 and enters the next process.

[0023] However, in actual production, it was found that during summer production, due to the hot and humid production environment of the rubber workshop, there are many mosquitoes. Mosquitoes often fly between the extruder and the cold water tank and hit the product belt being conveyed. At this time, the product belt is in the uncooled and softened stage, and the surface is sticky. After hitting the belt, the mosquitoes are stuck to it, causing contamination to the product.

[0024] In view of this, in order to solve the above problems, refer to Figures 1 to 3 As shown, it is worth noting that it also includes a shield long tube arranged between the discharge port and the through hole, and a closing and separating mechanism is arranged below the shield long tube;

[0025] The shield long tube is composed of two semi-ring-shaped bearing bushes 8 arranged opposite to each other, one end of the bearing bush 8 is slidably connected to the side wall of the extruder body 1, and the other end of the bearing bush 8 is slidably connected to the side wall of the cold water tank 2;

[0026] The closing and separating mechanism includes a base 4 arranged below the bearing bush 8 and a double-sided screw 10 arranged transversely between the base 4 and the bearing bush 8. Moving blocks 9 are respectively threadedly sleeved on both sides of the rod body of the double-sided screw 10. The two moving blocks 9 are fixed one-to-one with the two bearing bushes 8. The bottom surface of the moving block 9 is slidably connected to the top surface of the base 4. The base 4 is fixed on the cold water tank 2. The two ends of the double-sided screw 10 are respectively rotatably connected with fixed plates 3. The two fixed plates 3 are vertically fixed to the top surface of the base 4. A transmission component is arranged on one of the fixed plates 3.

[0027] Through the coordinated setting of the protective cover long cylinder and the closing and separating mechanism, when the rubber light strip needs to be produced, the rubber light strip is extruded through the discharge port of the extruder main body 1 and transported to the cold water tank 2 for cooling, and then the double-sided screw 10 is driven to rotate through the transmission component, and then the two moving blocks 9 are driven. The moving blocks 9 are restricted by the base 4 and can only extend on the top surface of the base 4 to make relative or opposite movements. The relative movement of the two moving blocks 9 closes the two bearings 8 and then covers the rubber light strip. Similarly, after the production is completed, the double-sided screw 10 is reversed, and then the two moving blocks 9 are driven to move oppositely, so that the two bearings 8 are separated and the rubber light strip on the discharge port is scraped off. In this way, the problem that there are many mosquitoes due to the hot and humid production environment of the rubber workshop during summer production can be solved. Mosquitoes often fly between the extruder and the cold water tank and hit the product belt being conveyed. At this time, the product belt is in the uncooled and softened stage, and the surface is sticky. The mosquitoes are stuck to the belt after hitting it, and then the product is polluted.

[0028] Further, refer to Figures 1 to 3 As shown, it is worth noting that the transmission component includes a rotating shaft 11 that rotates and penetrates into the cold water tank 2, a second satellite gear 13 fixedly sleeved at one end of the rotating shaft 11, and a first satellite gear 5 fixedly sleeved at the end of the double-sided screw 10, the first satellite gear 5 is located on the side of the fixed plate 3 away from the moving block 9, and a driving component is connected between the first satellite gear 5 and the second satellite gear 13;

[0029] The driving assembly includes a rotating rod 7 which is laterally arranged on one side of the first satellite gear 5. Gears 6 are fixedly sleeved on both ends of the rotating rod 7. One gear 6 is meshed with the first satellite gear 5, and the other gear 6 is meshed with the second satellite gear 13. The rotating rod 7 is rotated to penetrate into the cold water tank 2. A handle 12 is fixedly installed on the other end of the rotating shaft 11.

[0030] Through the arrangement of the transmission components and the driving assembly, when the two bearings 8 need to be closed to cover the light strip, the handle 12 can be rotated, and the second satellite gear 13 at the other end of the rotating shaft 11 can be driven by the handle 12, and one of the gears 6 can be driven to rotate by the rotation of the second satellite gear 13, and the rotation of one of the gears 6 drives the other gear 6 to rotate synchronously through the rotating rod 7, and the first satellite gear 5 is driven by the rotation of the gear 6, and the rotation of the first satellite gear 5 drives the double-sided screw 10, and the rotation of the double-sided screw 10 drives the moving block 9, and then drives the two bearings 8 to make relative motion, so that the two bearings 8 can be driven to close or separate while the handle 12 is turned, and the cooling water in the cold water tank 2 is used to cool the rotating shaft 11 and the second satellite gear 13 to prevent the operator from getting hot when turning the handle 12.
