Description

Technical Field

[0001] This utility model relates to the field of plastic pipe technology, specifically a plastic pipe sealing machine. Background Technology

[0002] Plastic pipes, as an important component of chemical building materials, are widely accepted by users due to their superior performance, hygiene, environmental protection, and low consumption. The main types include UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, polyethylene (PE) water supply pipes, and polypropylene PPR hot water pipes.

[0003] Chinese patent document with application number CN202020768102.9 in the related technology proposes a plastic pipe sealing machine. It connects the electrical components inside the device to an external power source, then rotates a fixed block of appropriate diameter and fixes it on the placement seat. The plastic pipe to be sealed is then vertically placed on the outside of the fixed block. The device is then started via the control panel. The third cylinder starts, raising the placement seat to a suitable height and then stopping. Then the first cylinder starts working, moving the right sealing strip to the left sealing strip to complete the edge sealing of the plastic pipe. Finally, the second cylinder starts, driving the cutting blade to quickly slide on the upper surfaces of the right and left sealing strips to complete the rapid edge trimming work at the sealing point.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist: the device facilitates the limiting and fixing of plastic pipes of different sizes by installing fixing blocks of different sizes. However, different sizes of fixing blocks need to be installed each time to process different plastic pipes. Furthermore, the contact between the fixing blocks and the plastic pipes causes frictional damage to the pipe walls. The large gap between the fixing blocks and the plastic pipes can cause the plastic pipes to tilt during processing, resulting in low practicality of the device. Therefore, a plastic pipe sealing machine is proposed to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 and Figure 7 A plastic pipe sealing machine in this embodiment includes a machine body 1, a first motor 2 and a turntable 3. The first motor 2 is installed at the lower end of the machine body 1, and the turntable 3 is fixed at the output end of the first motor 2. A clamping mechanism 4 is provided on the turntable 3, and an adjustment mechanism 5 is provided on the turntable 3.

[0026] The clamping mechanism 4 includes a first cavity 406 and a second motor 401 disposed in the turntable 3. The output end of the second motor 401 is fixed to the turntable. The upper end of the turntable 3 has two symmetrically distributed first cavities 406. A guide rod 407 is arranged laterally in the first cavity 406. A sliding seat 404 is slidably mounted on the guide rod 407. A connecting rod 402 is hinged between the sliding seat 404 and the turntable. A clamping plate is fixed on the sliding seat 404. Both the sliding seat 404 and the movable seat 508 are L-shaped.

[0027] The device works by starting the second motor 401, which drives the rotating plate 403 to rotate. The rotating plate 403 then drives the connecting rod 402 to move. The connecting rod 402, through its transmission action, causes the sliding seat 404 to move along the first cavity 406 under force, which in turn drives the first clamping plate 405 to move closer to the pipe until the inner side of the first clamping plate 405 and the outer side of the pipe are in a tight clamping state.

[0028] The clamping mechanism 4 includes a sliding groove 410 formed on both sides of the first cavity 406. A crossbar 409 is fixed on both sides of the sliding seat 404 and slides with the sliding groove 410. Folded cloth 408 is fixed on both sides of the sliding groove 410. The other end of the folded cloth 408 is fixed to the crossbar 409 and the folded cloth 408 is slidably connected to the sliding groove 410. The sliding seat 404 moves within the first cavity 406 to prevent grinding debris from falling into the first cavity 406, thus facilitating the subsequent cleaning of debris on the turntable 3.

[0029] The structure and operating principle of the motor and body 1 in this utility model have been disclosed in a plastic pipe sealing machine disclosed in Chinese patent application number CN202020768102.9, and their working principle will not be repeated here.

[0030] Please see Figure 2 , Figure 4 and Figure 6 In this embodiment, the adjustment mechanism 5 includes a second cavity 501 and a third cavity 505 opened in the middle of the turntable 3. Two fixing plates 504 are fixed in the third cavity 505. A threaded rod 507 is rotatably installed in the fixing plate 504. The other end of the threaded rod 507 is rotatably connected to the inner wall of the third cavity 505. A movable seat 508 is threadedly engaged on the threaded rod 507. A second clamping plate 509 is fixed on one side of the movable seat 508.

[0031] The device rotates the rotating rod 502, which drives the active bevel gear 503 to rotate. The active bevel gear 503 then meshes with the driven bevel gears 506 on both sides, causing the threaded rod 507 to rotate. The threaded rod 507 then drives the two moving seats 508 to move away from each other, so that the second clamping plate 509 abuts against the inner wall of the pipe, thereby further fixing the pipe.

[0032] The turntable 3 has a second cavity 501 connected to the third cavity 505. A rotatable rotating rod 502 is arranged horizontally in the second cavity 501. The other end of the rotating rod 502 is located outside the turntable 3, which is convenient for the operator to rotate the rotating rod 502. A driving bevel gear 503 is fixed to the end of the rotating rod 502. A driven bevel gear 506 that meshes with the driving bevel gear 503 is fixed to one end of the threaded rod 507, so that the driving bevel gear 503 meshes with the two driven bevel gears 506, thereby driving the threaded rod 507 to rotate.

[0033] The working principle of the above embodiments is as follows:

[0034] First, place the pipe on the turntable 3 so that the two second clamping plates 509 are inside the pipe. Then, rotate the rotating rod 502 to drive the active bevel gear 503 to rotate. The active bevel gear 503 then meshes with the driven bevel gears 506 on both sides, which in turn causes the threaded rod 507 to rotate. The threaded rod 507 then drives the two moving seats 508 to move away from each other, so that the second clamping plates 509 abut against the inner wall of the pipe to initially fix it.

[0035] Then, by starting the second motor 401, the second motor 401 drives the rotating plate 403 to rotate, and the rotating plate 403 drives the connecting rod 402 to move. Utilizing the transmission action of the connecting rod 402, the sliding seat 404 moves along the first cavity 406 after being subjected to force, thereby driving the first clamping plate 405 to move closer to the pipe until the inner side of the first clamping plate 405 is in a tight fit with the outer side of the pipe, thus ensuring the stability of the plastic pipe during the sealing operation.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
