Description

Technical Field

[0001] This utility model relates to a vacuum sizing device for pipes. Background Technology

[0002] Because nylon and PEBAX materials have poor melt strength, slow cooling, and are prone to sticking to the die after extrusion, they cannot be directly vacuum sizing. Therefore, it is necessary to cool the extruded material.

[0003] Pipe sizing devices are mainly used in the extrusion molding process of plastic pipes. They are typically installed on a vacuum chamber and aligned with the centerline of the extruder head to ensure that the molten plastic enters the sizing device uniformly and stably for cooling. Cooling is a crucial step in pipe production; its uniformity and timeliness significantly impact the quality of the finished pipe. Therefore, pre-cooling devices are often used to pre-cool the pipe to a suitable temperature. However, in actual production, the cooling length of the pipe cannot be adjusted, and the impact of water flow on the pipe cannot be controlled, easily causing watermarks and wavy patterns on the pipe.

[0004] In view of this, it is necessary to improve the existing vacuum sizing devices for pipes in order to solve the above problems. Utility Model Content

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] like Figures 1 to 3 As shown, the pipe vacuum sizing device 100 of this utility model includes a main body 1, a threaded connection part 2 protruding from the main body 1 toward one end, a vacuum sizing sleeve 3 fixed to the main body 1 and protruding from the main body 1 toward the side with the threaded connection part 2, a water-blocking adjustment part 4 disposed at the other end of the main body 1, a plurality of water injection parts 5, a plurality of screws 6 for fixing the water-blocking adjustment part 4, and a vacuum chamber.

[0023] A water storage cavity 11 is formed inside the main body 1, the threaded connection part 2 is integrally formed at one end of the main body 1, the vacuum chamber is threadedly connected to the threaded connection part 2, and the vacuum sizing sleeve 3 is housed inside the vacuum chamber.

[0024] The vacuum sizing sleeve 3 includes a head 31 and a rod 32. The main body 1 has an internal thread 12, and the head 31 has an external thread, which is threadedly connected to the internal thread 12. On the one hand, the height of the water storage cavity 11 can be changed by altering the relative position of the vacuum sizing sleeve 3 and the main body 1; on the other hand, vacuum sizing sleeves 3 with heads 31 of different heights can also be used to change the height of the water storage cavity. The rod 32 protrudes into the vacuum chamber from the middle of the threaded connection part 2. The vacuum sizing sleeve 3, the threaded connection part 2, and the main body 1 are all coaxially arranged.

[0025] By changing the relative position of the vacuum sizing sleeve 3 and the main body 1 or by changing the vacuum sizing sleeve 3, the height of the water storage chamber 11 can be adjusted, thereby adjusting the cooling length of the tube. Therefore, by simply replacing the vacuum sizing sleeve 3 with a different size and adjusting the height of the water storage chamber, products of any size can be made.

[0026] The water-blocking adjustment component 4 is provided with an exposed port 41 for communicating with the water storage chamber 11, and the size of the exposed port 41 is adjustable. The exposed port 41 is used to drain water from the water storage chamber 11. By adjusting the size of the exposed port 41, the speed at which water flows out of the water storage chamber 11 can be controlled, thereby controlling the impact of the water flow on the pipe body, avoiding water ripples and waves on the pipe body, making the pipe body smooth, flat, and dimensionally stable.

[0027] In this embodiment, the water-blocking adjustment component 4 includes a water-blocking ring 42, a telescopic plate 43, and an adjustment rod 44 for controlling the extension and retraction of the telescopic plate 43. The telescopic plate 43 extends and retracts to different positions to change the size of the exposed opening 41, that is, the exposed opening 41 is formed by the telescopic plate 43, and the extreme position is that the telescopic plate 43 is completely contained within the water-blocking ring 42. In this embodiment, the structure of the water-blocking adjustment component 4 is the same as that of an adjustable aperture structure for a camera.

[0028] The exposed opening 41 is circular and is always coaxially arranged with the main body 1.

[0029] The side wall of the water-blocking ring 42 is provided with a switch groove 45, and the adjusting rod 44 passes through the switch groove 45 and is connected to the telescopic plate 43. The switch groove 45 extends in the circumferential direction, and the user can control the extension and retraction of the telescopic plate 43 by holding the adjusting rod 44 and moving it along the switch groove 45. In this embodiment, the telescopic plate 43 extends and retracts radially vertically or obliquely.

[0030] Multiple screws 6 surround the water-blocking adjustment member 4 and are arranged in a circumferential array to fix the water-blocking adjustment member 4 onto the main body 1.

[0031] More specifically, a receiving step 13 is provided on the side of the main body 1 away from the threaded connection part 2. The water-blocking ring 42 is partially received within the receiving step 13, and partially protrudes outside the receiving step 13. The water-blocking ring 42 partially protrudes axially from the receiving step 13. In this embodiment, the switch groove 45 is located outside the receiving step 13 to facilitate user gripping.

[0032] The screw 6 includes a head and a body. The body is fixed to the main body 1, and the head fixes the water-blocking ring 42 to the receiving step 13 along the axial direction.

[0033] In this embodiment, the number of screws 6 is four.

[0034] The water injection component 5 is fixed around the main body 1 and communicates with the water storage cavity 11. In this embodiment, the water injection component 5 is fixed to the main body 1 by threads. Furthermore, the number of water injection components 5 is three.

[0035] The method of using the pipe vacuum sizing device 100 of this utility model is as follows: Select a vacuum sizing sleeve 3 of suitable size and install the selected vacuum sizing sleeve 3 into the main body 1, and control the installation position according to the required cooling length, and thread the vacuum water tank to the threaded connection part 2; after extrusion by the extruder, insert the pipe body into the pipe vacuum sizing device 100, add cooling water into the water storage chamber 11 through the water injection part 5, adjust the size of the exposed port 41 of the water baffle adjustment part 4 according to the size of the pipe and the water flow, open the vacuum device to make the vacuum chamber be in a vacuum state, and adjust the corresponding process according to the product size requirements.

[0036] The pipe vacuum sizing device 100 of this utility model can control the impact of water flow on the pipe body by setting a water-blocking adjustment component 4 with an adjustable exposure port 41, thereby avoiding water ripples and waves on the pipe body, making the pipe body smooth and flat, and dimensionally stable.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
