Description

Technical Field

[0001] This utility model relates to the field of leak detection technology for hose seals, specifically a leak detection device for hose seals. Background Technology

[0002] Tube filling and sealing mainly refers to the filling and sealing of plastic tubes as packaging containers. If the tube is not sealed properly after filling and sealing, there is a risk of leakage after a period of storage, especially for sterile products, which may be contaminated with microorganisms. Therefore, leak detection is necessary.

[0003] Existing leak detection devices for hose seals typically require complex and highly sensitive sensors or imaging devices, which are highly precise but also expensive and have poor applicability. Utility Model Content

[0004] The purpose of this invention is to provide a leak detection device for hose sealing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A leak detection device for sealing flexible hoses includes a mounting frame, a conveyor belt, and a leak detection assembly. The inner side of the mounting frame is provided with a conveyor belt, which has a mesh-like perforated structure. A limit component is provided on the left side of the mounting frame. An upper frame is fixed to the upper right side of the mounting frame, and a leak detection assembly is installed in the middle of the upper frame. The leak detection assembly includes a leak detection cylinder, a piston rod, a fixed frame, inserts, a leak detection pressure block, and a groove. The piston rod is provided on the lower side of the leak detection cylinder. A fixed frame is welded to the bottom of the piston rod, and inserts are fixed to the inner sides of both sides of the fixed frame. A leak detection pressure block is installed on the lower inner side of the fixed frame, and grooves are provided on both sides of the leak detection pressure block.

[0007] Furthermore, the limiting component includes a fixed bushing and a locking bolt. The fixed bushing is fixedly connected to the mounting frame, and the locking bolt passes through the upper side of the fixed bushing.

[0008] Furthermore, the limiting assembly also includes a connecting rod and a limiting plate. The connecting rod is slidably installed inside the fixed bushing, and the front end of the connecting rod is fixed with a limiting plate. The limiting plate has two positions, one at the front and one at the back.

[0009] Furthermore, the limiting plates are parallel to each other, and the limiting plates are located on the upper side of the conveyor belt and are slidably connected to the conveyor belt.

[0010] Furthermore, the leak detection block has an "I" shaped structure, and the grooves on both sides of the leak detection block are slidably connected to the block. Two connecting bolts pass through the upper side of the fixing frame.

[0011] Furthermore, a liquid storage frame is fixed to the lower inner side of the mounting frame, and the liquid storage frame is located on the lower side of the conveyor belt. The upper side of the liquid storage frame has an open structure, and the bottom of the liquid storage frame is connected to a drain pipe.

[0012] Furthermore, a support frame is installed below the mounting frame, and casters are installed at the bottom of the support frame.

[0013] Furthermore, threaded cylinders are embedded in the lower front and rear sides of the support frame, and threaded rods are screwed into the internal threads of the threaded cylinders, with positioning feet fixed at the bottom of the threaded rods.

[0014] The leak detection device for hose sealing provided by this utility model has the following beneficial effects:

[0015] This utility model is equipped with a leak detection component. The leak detection pressure block, which has an "I" shaped structure, can be slidably installed inside the fixed frame. The sliding fit between the groove and the insert facilitates the disassembly and assembly of the leak detection pressure block and ensures that the leak detection pressure block is firmly installed and not easy to loosen. The leak detection pressure block is easily locked by the connecting bolts. The extension and retraction of the leak detection cylinder and piston rod facilitates the raising and lowering of the fixed frame and the leak detection pressure block, so that the leak detection pressure block can press down on the sealed hose to generate pressure. If the hose is not sealed properly, it will burst, thereby realizing the hose leak detection.

[0016] This utility model is equipped with a limiting component. The conveyor belt is used to feed the packaged hose. The position of the limiting plate can be adjusted by moving the connecting rod inside the fixed bushing back and forth. After adjustment, the position of the connecting rod can be tightened by locking bolts. Similarly, the distance between the front and rear limiting plates can be adjusted to limit the feeding of the hose on the conveyor belt, so that the packaged hose can move forward along the channel between the two limiting plates to the position of the leak detection component.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 and Figure 3 As shown, the leak detection device for hose sealing of this utility model includes a mounting frame 1, a conveyor belt 2 and a leak detection component 5. The inner side of the mounting frame 1 is provided with the conveyor belt 2, and the conveyor belt 2 has a mesh hollow structure. The left side of the mounting frame 1 is provided with a limiting component 3.

[0023] The limiting component 3 includes a fixed bushing 301 and a locking bolt 302. The fixed bushing 301 is fixedly connected to the mounting frame 1, and the locking bolt 302 passes through the upper side of the fixed bushing 301. The limiting component 3 also includes a connecting rod 303 and a limiting plate 304. The connecting rod 303 is slidably installed inside the fixed bushing 301, and the front end of the connecting rod 303 is fixed with the limiting plate 304. There are two limiting plates 304, one in front and one behind, which are parallel to each other. The limiting plate 304 is located on the upper side of the conveyor belt 2 and is slidably connected to the conveyor belt 2. A liquid storage frame 6 is fixed on the lower inner side of the mounting frame 1, and the liquid storage frame 6 is located on the lower side of the conveyor belt 2. The upper side of the liquid storage frame 6 has an open structure, and the bottom of the liquid storage frame 6 is connected to a drain pipe 7.

[0024] The conveyor belt 2 feeds the packaged hose. The position of the limiting plate 304 can be adjusted by moving the connecting rod 303 inside the fixed bushing 301 back and forth. After adjustment, the position of the connecting rod 303 can be tightened by the locking bolt 302. Similarly, the distance between the two limiting plates 304 can be adjusted to limit the feeding of the hose on the conveyor belt 2, so that the packaged hose can move forward along the channel between the two limiting plates 304 to the position of the leak detection component 5. The height of the positioning feet 12 can be adjusted by rotating the threaded rod 11 inside the threaded cylinder 10, which can be used on uneven bottom surfaces, so that the four positioning feet 12 can cooperate with each other to provide stable support for the mounting frame 1.

[0025] like Figures 1-2As shown, an upper frame 4 is fixed to the upper right side of the mounting frame 1, and a leak detection component 5 is installed in the middle of the upper frame 4.

[0026] In some embodiments, the leak detection assembly 5 includes a leak detection cylinder 501, a piston rod 502, a fixing frame 503, an insert 504, a leak detection pressure block 505, and a groove 506. The piston rod 502 is provided on the lower side of the leak detection cylinder 501. The fixing frame 503 is welded to the bottom of the piston rod 502. An insert 504 is fixed on the inner side of both sides of the fixing frame 503. The leak detection pressure block 505 is installed on the lower inner side of the fixing frame 503. A groove 506 is provided on both sides of the leak detection pressure block 505. The leak detection pressure block 505 has an "I" shaped structure. The grooves 506 on both sides of the leak detection pressure block 505 are slidably connected to the insert 504. Two connecting bolts pass through the upper side of the fixing frame 503. A liquid storage frame 6 is fixed on the lower inner side of the mounting frame 1. The liquid storage frame 6 is located on the lower side of the conveyor belt 2. The upper side of the liquid storage frame 6 has an open structure. A drain pipe 7 is connected to the bottom of the liquid storage frame 6.

[0027] The leak detection block 505, which has an "I" shaped structure, can be slidably installed inside the fixed frame 503. The sliding fit between the groove 506 and the insert 504 facilitates the disassembly and assembly of the leak detection block 505 and makes the leak detection block 505 firmly installed and not easy to loosen. The connecting bolts facilitate the locking of the leak detection block 505. The extension and retraction of the leak detection cylinder 501 and the piston rod 502 facilitates the lifting and lowering of the fixed frame 503 and the leak detection block 505, so that the leak detection block 505 can press down on the sealed hose to generate pressure. If the hose is not sealed tightly, it will burst, thereby realizing the hose leak detection. The leaked liquid can seep into the interior of the liquid storage frame 6 through the hollow conveyor belt 2. The liquid storage frame 6 is located on the lower side of the conveyor belt 2 and has an open structure to facilitate material collection. Finally, the liquid is drained through the drain pipe 7 at its bottom.

[0028] like Figures 1-3 As shown, when using the leak detection device for sealing the hose, first adjust the position of the limiting plate 304 by moving the connecting rod 303 inside the fixed bushing 301 back and forth. After adjustment, tighten the position of the connecting rod 303 by locking bolt 302. Similarly, the distance between the two limiting plates 304 can be adjusted so that it can limit the feeding of the hose on the conveyor belt 2. After filling and sealing, the hose falls between the two limiting plates 304.

[0029] Then, the sealed hose is fed by the conveyor belt 2, allowing it to advance along the channel between the two limiting plates 304 to the position of the leak detection component 5. After being identified by the photoelectric sensor, and after a certain delay, the extension and retraction of the leak detection cylinder 501 and piston rod 502 drives the lifting and lowering of the fixed frame 503 and the leak detection pressure block 505. This allows the leak detection pressure block 505 to press down on the sealed hose, generating pressure. If the hose is not properly sealed, it will burst, thus achieving hose leak detection. The leaked liquid can then pass through the perforated structure and drive the conveyor belt. 2. The liquid seeps into the interior of the liquid storage frame 6, which is located below the conveyor belt 2 and has an open structure for easy material collection. Finally, the liquid is drained through the drain pipe 7 at its bottom. The leak detection pressure block 505, which has an "I" shaped structure, can be easily slidably installed into the interior of the fixed frame 503. The sliding fit between the groove 506 and the insert 504 facilitates the disassembly and assembly of the leak detection pressure block 505 and ensures that the leak detection pressure block 505 is installed firmly and not easily loosened. After installation, the leak detection pressure block 505 can be locked with connecting bolts. This completes the use process of the leak detection device for the hose sealing.
