Abstract
Description
Technical Field
[0001] This utility model relates to the field of machine head fixing technology, specifically to a novel machine head fixing device. Background Technology
[0002] Currently, the connection between the die head and the main body of equipment such as extruders is generally secured manually. During the equipment preheating stage, secondary tightening is difficult to perform, and this traditional method has several drawbacks. First, the tightening effect is affected by operator experience and environmental factors, making it difficult to guarantee consistency. Second, this method cannot meet the high-temperature operation requirements of the equipment. During equipment operation, the temperature of the die head and connecting parts rises rapidly. Direct manual tightening not only poses safety hazards such as burns and mechanical injuries, but also limits operation and makes real-time dynamic adjustments difficult. As the equipment operates, thermal expansion increases the risk of loosening of the die head connection, easily leading to material leakage, which in turn affects production continuity, product quality, reduces material utilization, and brings multiple adverse effects to production.
[0003] Therefore, we propose a new type of head fixing device. Utility Model Content
[0004] The main purpose of this utility model is to provide a novel machine head fixing device. Through the threaded connection between the fixing flange and the machine head flange, and the precise cooperation between the first fastener, the second fastener and the external hexagon in the strengthening mechanism, a standardized fastening operation can be achieved; this can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A novel machine head fixing device includes a machine head flange, a fixing flange, and a ball joint connecting rod. One end of the fixing flange is provided with a mounting groove for installing the ball joint connecting rod. One end of the ball joint connecting rod is located in the mounting groove. The fixing flange is sleeved on the ball joint connecting rod. The end of the fixing flange near the mounting groove is threaded to one end of the machine head flange. The outer side of the fixing flange away from the machine head flange is provided with an external hexagon. A reinforcing mechanism is installed at the external hexagon of the fixing flange. The reinforcing mechanism includes a first fastener, a second fastener, an arc-shaped component, an anti-slip sleeve, a sealing gasket, and a first insert plate. The first fastener and the second fastener are fastened to each other on the outer hexagon. The first fastener and the second fastener are provided with a limiting groove that matches the outer hexagon on the side near the outer hexagon. The first fastener and the second fastener are fixedly connected by bolts.
[0006] By adopting the above technical solution, through the threaded connection between the fixed flange and the machine head flange, and by strengthening the precise fit between the first fastener, the second fastener and the external hexagon in the mechanism, standardized fastening operations can be achieved; this greatly improves the stability and reliability of the machine head fixing and ensures the stability of equipment operation.
[0007] Specifically, a first insert plate is fixedly connected to the top of the first fastener near the end of the second fastener, and a second insert plate is fixedly connected to the bottom of the second fastener near the end of the first fastener.
[0008] Specifically, the top of the second fastener is provided with a first slot that matches the first insert plate, and the bottom of the first fastener is provided with a second slot that matches the second insert plate.

[0010] Specifically, both the first fastener and the second fastener have a first through hole at one end, and an arc-shaped component is fixedly connected to the side of the first fastener and the second fastener away from the first through hole.
[0011] Specifically, the first fastener and the second fastener are provided with a second through hole on the side near the arc-shaped part, and a sealing gasket is fixedly glued to the inner wall of the arc-shaped part.

[0016] As one embodiment of this utility model, such as Figures 1-4 As shown, the present invention discloses a novel machine head fixing device, comprising a machine head flange 1, a fixing flange 2, and a ball joint connecting rod 3. One end of the fixing flange 2 is provided with a mounting groove for mounting the ball joint connecting rod 3, and one end of the ball joint connecting rod 3 is located in the mounting groove. The fixing flange 2 is sleeved on the ball joint connecting rod 3. The end of the fixing flange 2 near the mounting groove is threadedly connected to one end of the machine head flange 1. The outer side of the fixed flange 2 away from the machine head flange 1 is provided with an external hexagon 201, and a reinforcing mechanism 4 is installed at the external hexagon 201 of the fixing flange 2. The reinforcing mechanism 4 includes a first fastener 5, a second fastener 6, an arc-shaped component 7, an anti-slip sleeve 9, a sealing gasket 12, and a first insert plate 14. The first fastener 5 and the second fastener 6 are fastened to each other on the outer hexagon 201. The first fastener 5 and the second fastener 6 are provided with a limiting groove 10 that is adapted to the outer hexagon 201 on the side near the outer hexagon 201. The first fastener 5 and the second fastener 6 are fixedly connected by bolts.
[0017] During use, if the connection parts become loose due to thermal expansion or other factors during equipment operation, the operator can easily apply rotational torque through the anti-slip sleeve 9 on the outside of the first fastener 5 and the second fastener 6, thereby conveniently operating the reinforcing mechanism 4. By using the reinforcing mechanism 4, the external hexagon 201 and tools, the fixed flange 2 can be further tightened without direct contact with high-temperature parts. The reinforcing mechanism 4 can protect the external hexagon 201, preventing it from being worn, and can also increase the width of the external hexagon 201, making it easier to operate.
[0018] The present invention also includes a first insert plate 14 fixedly connected to the top end of the first fastener 5 near the end of the second fastener 6, and a second insert plate fixedly connected to the bottom end of the second fastener 6 near the end of the first fastener 5.

[0023] In use, the die head flange 1 is connected to the main body of the equipment. The die head flange 1 is fixed to the extruder by a specific connecting mechanism. One end of the ball head connecting rod 3 is installed into the mounting groove at one end of the fixed flange 2, so that the fixed flange 2 is fitted onto the ball head connecting rod 3. Then, the end of the fixed flange 2 near the mounting groove is connected to one end of the die head flange 1 by threads, completing the initial installation of the die head flange 1 and the fixed flange 2. Then, the first fastener 5 and the second fastener 6 are fastened to the external hexagon 201. Fastener 5 and second fastener 6 are provided with limiting grooves 10 that are adapted to the external hexagon 201 on the side near the external hexagon 201, which can accurately cooperate with the external hexagon 201 and ensure the stability of the fastening. When fastening, the first insert plate 14 at the top of the first fastener 5 is inserted into the first slot 13 at the top of the second fastener 6, and at the same time, the second insert plate at the bottom of the second fastener 6 is inserted into the second slot at the bottom of the first fastener 5.
