[0001] This utility model relates to the field of airbag extrusion machine technology, and in particular to an airbag extrusion machine head. Background Technology

[0002] In the processing of plastics and the production of rubber products, extrusion is a crucial step. An extruder heats and compresses plastic or rubber raw materials, turning them into a continuous molten material, which is then molded into the desired product through a die.

[0003] However, during the extrusion process, the raw materials may contain various impurities, such as dust, metal fragments, and unmelted plastic particles. If these impurities are not removed in time, they will seriously affect the quality and performance of the product.

[0004] Therefore, we propose a novel airbag extrusion machine head. Utility Model Content

[0005] The purpose of this invention is to address the problem that in existing devices, various impurities may be present in the raw materials during the extrusion process, such as dust, metal fragments, and unmelted plastic particles. If these impurities are not removed in time, they will seriously affect the quality and performance of the product.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an airbag extrusion machine head, comprising a machine head body, wherein a cooling water channel is provided inside the machine head body, and a rotating arm hinge seat is connected to both sides of the front end of the machine head body; a filter glue front machine head is connected to the surface of one set of rotating arm hinge seats, and an extrusion front machine head is connected to the surface of the other set of rotating arm hinge seats; hydraulic cylinders are connected to the bottom of both sides of the machine head body, and the output ends of the two sets of hydraulic cylinders are respectively connected to a first ring clamp and a second clamping ring; an inner clasp is connected to the inner wall of the extrusion front machine head, and an outer clasp is connected to the outer wall of the extrusion front machine head; a self-aligning set screw is connected inside the extrusion front machine head; and a pressure sensing alarm device is connected to the inner wall of the machine head body.

[0007] Furthermore, the front head of the filter head is equipped with a disassembly assembly, which includes a filter screen. Positioning blocks are connected to both sides of the filter screen, and the filter screen can block most impurities from entering the molten material.

[0008] Furthermore, the positioning block is connected to a fixing block on both sides of the top of the filter screen. The fixing block has a slot inside, which allows the filter screen to be easily installed and fixed.

[0009] Furthermore, a screw is inserted into the inside of the slot, a bearing sleeve is connected to one side surface of the screw, and a moving block is connected to the other side surface of the screw. The bearing sleeve can improve the stability of the screw when it rotates, and the moving block can be easily moved by rotating the screw.

[0010] Furthermore, the movable block has a threaded hole inside, and the screw is connected to the movable block through the threaded hole. The positioning block has a slot on its surface that matches the movable block. When the movable block moves, it will be inserted into the slot of the positioning block for fixation.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the pressure sensor alarm device can monitor the pressure changes during the extrusion process in real time.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. 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.

[0020] Examples, such as Figure 1 - Figure 4 As shown, this utility model provides an airbag extrusion machine head, including a machine head body 1. The machine head body 1 has a cooling water channel 2 inside. Both sides of the front end of the machine head body 1 are connected to a rotating arm hinge seat 3. A filter glue front machine head 4 is connected to the surface of one set of rotating arm hinge seats 3, and an extrusion front machine head 5 is connected to the surface of the other set of rotating arm hinge seats 3. Both sides of the bottom of the machine head body 1 are connected to hydraulic cylinders 6. The output ends of the two sets of hydraulic cylinders 6 are respectively connected to a first ring clamp 7 and a second clamping ring 12. The inner wall of the extrusion front machine head 5 is connected to an inner ferrule 9, the outer wall of the extrusion front machine head 5 is connected to an outer ferrule 8, the inside of the extrusion front machine head 5 is connected to a self-aligning set screw 10, and the inner wall of the machine head body 1 is connected to a pressure sensing alarm device 11.

[0021] like Figure 3 and Figure 4 As shown, the front head 4 of the filter is equipped with a disassembly assembly 13. The disassembly assembly 13 includes a filter screen 1301. Positioning blocks 1302 are connected to both sides of the filter screen 1301. The filter screen 1301 can block most impurities from entering the molten material.

[0022] like Figure 4 The positioning block 1302 is connected to the top of both sides of the filter screen 1301 by a fixing block 1303. The fixing block 1303 has a slot 1304 inside, which can be used to install and fix the filter screen 1301.

[0023] like Figure 4 As shown, a screw 1305 is inserted into the slot 1304. A bearing sleeve 1306 is connected to one side surface of the screw 1305, and a moving block 1307 is connected to the other side surface of the screw 1305. The bearing sleeve 1306 can improve the stability of the screw 1305 when rotating, and the moving block 1307 can be moved easily by rotating the screw 1305.

[0024] like Figure 1 and Figure 4As shown, the movable block 1307 has a threaded hole 1308 inside, and the screw 1305 is threadedly connected to the movable block 1307 through the threaded hole 1308. The positioning block 1302 has a slot that matches the movable block 1307 on its surface. When the movable block 1307 moves, it will be inserted into the slot of the positioning block 1302 for fixation.

[0025] The overall effect of this embodiment is as follows: the self-aligning top screw 10 can adjust the center of the inner liner 9 of the flow divider shuttle, finely adjust the eccentricity of the tube, and the first ring clamp 7 and the second clamping ring 12 driven by the hydraulic cylinder 6 are locked / released with the rear transition section. After the C-shaped clamping ring is released, the operator can manually turn the front head of the pneumatic tire to the left by about 120 degrees and the front head of the filter rubber 4 to the right by about 120 degrees. When facing the head, the operator can turn the head to the left and right to switch between pneumatic tire extrusion and filter rubber sheet extrusion operations. The filter screen 1301 used in the extrusion process plays a crucial role in blocking most impurities from entering the molten material. However, the filter screen 1301 may break during use due to prolonged operation and exposure to high temperature and pressure. Once the filter screen is broken, impurities in the molten material will cause pressure fluctuations. The pressure sensing alarm device 11 can quickly detect this change and issue an alarm signal, thereby reminding the operator to stop the machine in time to check the filter screen and prevent impurities from further contaminating the product. When replacing the filter screen 1301, the screw 1305 can be rotated forward so that the screw 1305 can rotate forward with the moving block 1307, thereby driving the moving block 1307 to retract inward and be pulled out from the slot of the fixed block 1303. Then, pull the filter screen 1301 upward to remove the broken filter screen 1301. At this time, insert the new filter screen 1301 into the filter head 4 and rotate the screw 1305 in the opposite direction so that the moving block 1307 moves outward by rotating in the opposite direction and is inserted into the slot of the fixed block 1303 for fixing. This completes the convenient replacement of the filter screen 1301.

[0026] Working principle: The pressure sensor alarm device 11 can monitor the pressure changes during the extrusion process in real time. When the filter screen 1301 is damaged, impurities in the molten material will cause pressure fluctuations. The pressure sensor alarm device 11 can quickly detect this change and issue an alarm signal, thereby reminding the operator to stop the machine in time to check the filter screen 1301 and prevent impurities from further contaminating the product.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the 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. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
