Description

Technical Field

[0001] This utility model relates to the field of extruder technology, and in particular to a filter screen cleaning mechanism for an internal rubber extruder. Background Technology

[0002] An inner rubber extruder is a mechanical device used in rubber processing to extrude the inner layer of rubber compound (inner rubber). This type of equipment plays a crucial role in the production of rubber products, particularly in the manufacture of tires, hoses, and sealing strips.

[0003] During production, the rubber material inside the extruder needs to be filtered through a filter screen. After the spiral-flowing rubber material passes through the filter screen, the rotational force decreases, and most of the rubber material flows in a straight line. However, after prolonged use, the filter screen needs to be replaced and cleaned, otherwise it will affect subsequent extrusion. But the replacement efficiency of the existing filter screen is too low, and after disassembly, cleaning, and reinstallation, the machine needs to be shut down for a period of time, which reduces work efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a filter screen cleaning mechanism for an inner rubber extruder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] Preferably, the cleaning assembly includes a bracket mounted on the back of the workbench, a motor II fixedly mounted on one side of the bracket, and a cleaning brush fixedly sleeved on the output shaft of the motor II.

[0010] Preferably, when one of the extruder heads is installed at the extrusion port, the filter screen and cleaning brush in another extruder head that is distributed at a 90-degree angle to the extruder head are located in the same horizontal plane.

[0011] Preferably, a plurality of evenly distributed limiting rods are fixedly connected to one side of the movable plate, and the side of the limiting rods away from the movable plate passes through the workbench and is fixedly connected to a limiting plate.

[0012] Preferably, the end of the extrusion port facing the extrusion head is provided with an outer notch and an inner fitting, and the end of the extrusion head facing the extrusion port is integrally formed with a surrounding platform and a docking platform.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figure 1-5 As shown, this utility model provides a filter screen cleaning mechanism for an internal rubber extruder, including a worktable 1 and an extruder body 2 installed above the worktable 1. One end of the extruder body 2 is provided with an extrusion port 3. A cylinder 4 is installed on the worktable 1. A reversing mechanism 5 is installed on the movable end of the cylinder 4. A cross connecting plate 6 is provided on one side of the reversing mechanism 5. Extrusion heads 7 that can match the extrusion port 3 are fixedly installed at the four ends of the cross connecting plate 6. A filter screen 8 is fixedly connected inside the extrusion head 7. A cleaning component 9 for cleaning the filter screen 8 is installed on the back of the worktable 1.

[0025] In this embodiment, the reversing mechanism 5 includes a movable plate 51, which is fixedly connected to the output shaft of the cylinder 4. A motor I 52 is fixedly installed on the side of the movable plate 51 near the cylinder 4. The output shaft of the motor I 52 passes through the movable plate 51 and is fixedly sleeved with a main gear 53. A rotating shaft 54 ​​is rotatably arranged on the side of the movable plate 51 away from the cylinder 4. A secondary gear 55 meshing with the main gear 53 is fixedly sleeved on the outer wall of the rotating shaft 54. A cross connecting plate 6 is fixedly connected to the end of the rotating shaft 54. The motor I 52 drives the main gear 53 to rotate and drives the secondary gear 55 to rotate. The rotation of the secondary gear 55 causes the rotating shaft 54 ​​to drive the cross connecting plate 6 to rotate, thereby realizing the transfer of the extrusion head 7.

[0026] In this embodiment, motor I 52 is controlled by touch and rotates one revolution each time. The number of teeth of the auxiliary gear 55 is four times the number of teeth of the main gear 53. Motor I 52 drives the main gear 53 to rotate one revolution each time, thereby causing the auxiliary gear 55 to rotate one-quarter revolution, that is, the extruder 7 rotates 90 degrees each time.

[0027] In this embodiment, the cleaning component 9 includes a bracket 91 installed on the back of the workbench 1. A motor II 92 is fixedly installed on one side of the bracket 91. A cleaning brush 93 is fixedly sleeved on the output shaft of the motor II 92. The bracket 91 supports the motor II 92, and the motor II 92 drives the cleaning brush 93 to clean the filter screen 8.

[0028] In this embodiment, when one of the extrusion heads 7 is installed in the extrusion port 3, the filter screen 8 and cleaning brush 93 in the other extrusion head 7, which is distributed at a 90-degree angle to the extrusion head 7, are located in the same horizontal plane, and the cleaning brush 93 can contact the filter screen 8 to achieve cleaning.

[0029] In this embodiment, a plurality of evenly distributed limiting rods 56 are fixedly connected to one side of the moving plate 51. The side of the limiting rods 56 away from the moving plate 51 passes through the workbench 1 and is fixedly connected to the limiting plate 57. The moving plate 51 is limited by the limiting rods 56 and the limiting plate 57, so that the moving plate 51 moves stably.

[0030] In this embodiment, the end of the extrusion port 3 facing the extrusion head 7 is provided with an outer notch 31 and an inner fitting 32. The end of the extrusion head 7 facing the extrusion port 3 is integrally formed with a surrounding platform 71 and a docking platform 72. The filter screen 8 is fixedly connected to the inner ring of the docking platform 72. When the extrusion head 7 and the extrusion port 3 are connected, the surrounding platform 71 covers the extrusion port 3 and is located in the outer notch 31, and the docking platform 72 is inserted into the inner fitting 32. Sealing gaskets 33 are embedded on the end faces of the outer notch 31 and the inner fitting 32. When the extrusion head 7 and the extrusion port 3 are connected, the surrounding platform 71 and the docking platform 72 respectively abut against the corresponding sealing gaskets 33. By having the surrounding platform 71 cover the extrusion port 3 and be located in the outer notch 31, and the docking platform 72 is inserted into the inner fitting 32, and the surrounding platform 71 and the docking platform 72 respectively abut against the corresponding sealing gaskets 33, the connection between the extrusion head 7 and the extrusion port 3 is stable and has good sealing performance.

[0031] How to use and how to work this device:

[0032] First, internal rubber extrusion is achieved through the extruder body 2. During the extrusion process, the rotational force decreases after filtration by the filter screen 8, and most of the rubber flows in a straight line. The rubber can be discharged through the extrusion port 3 and the extrusion head 7. After prolonged use, the filter screen 8 needs to be replaced and cleaned, otherwise it will affect subsequent extrusion. The cylinder 4 pushes the moving plate 51 to move, and the moving plate 51 drives the cross connecting plate 6 through the rotating shaft 54 ​​to move the extrusion head 7 until the extrusion head 7 is completely separated from the extrusion port 3. Then, the touch control makes the motor I 52 rotate one revolution. The motor I 52 drives the main gear 53 to rotate one revolution, and the main gear 53 drives the auxiliary gear 55 meshing with it to rotate 90°, which is in turn related to the extrusion head 7. The extruder head 7 separated from the outlet 3 rotates 90° to the position of the cleaning brush 93, and another extruder head 7 at an angle of 90° reaches the position of the extrusion port 3. The filter screen 8 inside is clean. At this time, the control cylinder 4 retracts and the moving plate 51 resets. The extruder head 7 with the clean filter screen 8 is installed on the extrusion port 3. The filter screen 8 inside the replaced extruder head 7 comes into contact with the cleaning brush 93. The motor II 92 drives the cleaning brush 93 to rotate for cleaning. Water can be added for rinsing during the cleaning process. This allows the extruder body 2 to continue working while cleaning, without having to stop and wait. This facilitates cleaning without affecting the work process and improves work efficiency.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
