Description

Technical Field

[0001] The utility model belongs to the technical field of extruders, and particularly relates to an extruder with a protective function at the extrusion head. Background Art

[0002] In the fields of plastic processing and related industrial production, extruders are commonly used equipment. However, there are often some problems in the extrusion head part of traditional extruders. The extrusion heads of early extruders usually did not have special protective devices. During the production process, the extrusion head was directly exposed to the external environment and was prone to being invaded by dust, impurities, and foreign objects, which might lead to a decline in the quality of the extruded products, resulting in defects or flaws. Without protection, operators might accidentally touch the high-temperature extrusion head during work, causing safety accidents such as burns. In addition, the unprotected extrusion head was also easily damaged by external collisions, increasing the equipment maintenance cost and downtime, and affecting the production efficiency. In some industries with high requirements for product quality and production environment, such as the electronics and medical fields, these deficiencies of the extrusion heads of traditional extruders are particularly prominent, and there is an urgent need for an extruder with a protective function to solve these problems and improve production safety, product quality, and production efficiency. Publication No.: CN218171300U discloses an extruder that is easy to clean, including a device base. On one side of the upper end of the device base, there is an output motor; on the outside of the sliding connection block, one side is slidably connected to the inside of the horizontal sliding rail, one side of the sliding connection block is slidably connected to one side of the output motor, the output shaft of the output motor is fixedly connected to one end of the first transmission extrusion rod, the other end of the first transmission extrusion rod is provided with a second transmission extrusion rod, and the lower end of the bearing sliding plate is fixedly connected to the upper end of the device base. By horizontally moving the sliding connection block outside the horizontal sliding rail, during the horizontal movement, the first transmission extrusion rod can be pulled horizontally by the output motor, separating the first transmission extrusion rod and the extrusion frame, facilitating the cleaning of the extrusion frame and the first transmission extrusion rod, improving the cleaning efficiency, and also improving the cleaning effect, avoiding the need to rely on other devices for assistance during the cleaning process.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific situations.

[0033] In one embodiment of the present utility model, as Figures 1 - 4 shown, an extruder with a protective function for the extrusion head is provided, which includes a machine body 1. A machine door 2 is rotatably connected to the surface of the machine body 1. A first fixing block 3 is fixedly installed at the top end of the machine body 1. A feeding hopper 4 is fixedly installed at the top end of the first fixing block 3. A motor 5 is fixed inside the machine body 1. A screw conveyor 6 is fixedly installed at the output end of the motor 5. An extrusion head 7 is fixedly installed at the side end of the machine body 1. A second fixing block 8 is fixedly installed on the surface of the machine body 1. A protective cover 9 is fixedly installed at the front end of the second fixing block 8. A fixing groove 10 is opened at the top end of the second fixing block 8. A hydraulic cylinder 11 is fixed inside the fixing groove 10. A fixing plate 12 is fixedly installed at the output end of the hydraulic cylinder 11. A support rod 13 is fixedly installed at the bottom end of the fixing plate 12. A moving groove 14 is opened on the surface of the second fixing block 8. A cutting knife 15 is fixedly installed at the bottom end of the fixing plate 12. A silica gel ring 16 is fixedly installed on the surface of the protective cover 9. A closing cover 17 is sleeved on the outer surfaces of both the silica gel ring 16 and the protective cover 9. By starting the movement of the hydraulic cylinder 11, the movement of the hydraulic cylinder 11 drives the fixing plate 12 to move. Then, the movement of the fixing plate 12 drives the support rod 13 to move. Subsequently, the movement of the fixing plate 12 drives the cutting knife 15 to move inside the moving groove 14, and thus it is possible to realize the cutting of the extruded material.

[0034] As Figure 3 、 5 shown, a slot 18 is opened on the surface of the first fixing block 3. A filter plate 19 is inserted into the slot 18. Sliding grooves 20 are opened on the surfaces of both the filter plate 19 and the slot 18. A spring 21 is fixedly installed inside the sliding groove 20. The other end of the spring 21 is fixedly installed with an arc-shaped block 22. A sealing plate 23 is inserted into the surface of the first fixing block 3. By pulling the filter plate 19, the movement of the filter plate 19 drives the arc-shaped block 22 to perform a squeezing movement. Then, the squeezing movement of the arc-shaped block 22 drives the spring 21 to perform a squeezing movement. Subsequently, the arc-shaped block 22 is disengaged from the sliding groove 20 inside the filter plate 19. Then, the filter plate 19 is disengaged from the device, and thus the filter plate 19 can be cleaned, maintained, or replaced.

[0035] At least one of the above embodiments of the present utility model can at least achieve that when the staff uses the device, the material to be extruded is poured into the feed hopper 4, and the material enters the interior of the machine body 1 through the first fixing block 3. The motor 5 in the machine body 1 is started to drive the auger 6 to rotate, and the auger 6 pushes the material towards the extrusion head 7 and finally extrudes and forms from the extrusion head 7. During the extrusion process, the protective cover 9 at the front end of the second fixing block 8 protects the extrusion head 7 to prevent external objects from interfering or causing harm to the operator. At the same time, the silica gel ring 16 and the sleeved closing cover 17 further enhance the protection effect to avoid foreign objects from entering. When it is necessary to cut the extruded material, the hydraulic cylinder 11 in the fixed groove 10 is started to push the fixing plate 12 to move downward. The support rod 13 at the bottom end of the fixing plate 12 moves inside the second fixing block 8 to ensure the stability of the movement of the fixing plate 12. The fixing plate 12 drives the cutting knife 15 to move downward along the moving groove 14 to cut the extruded material. During the feeding stage, the material first passes through the filter plate 19 at the first fixing block 3 for filtering to remove impurities and improve the quality of the extruded product. The filter plate 19 is clamped in the slot 18 under the action of the spring 21 through the arc-shaped block 22 to ensure its stable position. The sealing plate 23 is fixed on the surface of the first fixing block 3 by bolts to prevent the filter plate 19 from coming out. When the staff replaces the filter plate 19, first rotate the bolt to disconnect the sealing plate 23 from the device, then pull the filter plate 19. The movement of the filter plate 19 drives the arc-shaped block 22 to perform a squeezing movement, and then drives the spring 21 to perform a squeezing movement through the squeezing movement of the arc-shaped block 22. Subsequently, the arc-shaped block 22 is disengaged from the chute 20 inside the filter plate 19, and then the filter plate 19 is disengaged from the device, and the filter plate 19 can be cleaned, maintained or replaced.

[0036] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
