Description

Technical Field

[0001] This utility model relates to the field of secondary circulation pipeline technology for hot presses, specifically a secondary circulation pipeline structure for improving hot pressing temperature. Background Technology

[0002] Planks are flat, slender, rectangular pieces of wood, with their parallel surfaces longer than their width. Primarily used in woodworking, planks play a vital role in the construction of ships, houses, bridges, and many other structures. They are also used as supports for shelves and tables. Hot presses are a common processing tool used in hot pressing processes, shaping materials into desired forms under high temperature and pressure. They are widely used in wood processing, furniture manufacturing, and architectural decoration.

[0003] For example, in the case of a wood board hot press disclosed in announcement number CN221583934U, the hot press plate is usually heated by steam through a circulating pipe. To ensure the sealing of the connection between the secondary circulation pipe and the hot press plate, a sealing ring is installed at the connection. The sealing ring is sealed by compression. However, with prolonged use, the sealing ring will age faster after repeated heating and cooling, affecting the normal sealing. If the staff fails to detect the aging of the sealing ring in time and replace it, steam leakage may occur, resulting in insufficient hot pressing temperature. Therefore, we propose a secondary circulation pipe structure to improve the hot pressing temperature. Utility Model Content

[0004] The purpose of this invention is to provide a secondary circulation pipeline structure that improves the hot-pressing temperature, 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: a secondary circulation pipeline structure for improving hot pressing temperature, comprising a secondary circulation pipeline disposed on the top of a hot pressing plate, wherein the secondary circulation pipeline and the hot pressing plate are provided with an installation sealing mechanism, the installation sealing mechanism being composed of a connector, an installation head, a sealing bearing and a sealing ring, and the top of the installation head being provided with a driven component for alerting workers of leaks.

[0006] Preferably, the driven component includes a piston tube fixed to the top of the mounting head. The piston tube has an internal piston chamber, an air outlet at the top, and an air inlet at the bottom. A push plate is connected to the internal piston of the piston tube. A rubber rope is fixed to the side of the push plate away from the air inlet, and the end of the rubber rope away from the push plate is fixed to the inner wall of the piston chamber. A reminder rod is fixed to the side of the push plate near the rubber rope. The reminder rod passes through the piston tube and is connected to the piston. A one-way assembly for air outlet is provided at the top of the piston tube. The piston tube communicates with the mounting head through the bottom air inlet. When the secondary circulation pipe is installed on the hot press plate via the sealing mechanism, the sealing ring blocks the air inlet at the bottom of the piston tube. At this time, simply pushing the reminder rod causes the push plate to move towards the side closer to the air inlet. When the air inlet is blocked, gas can only be discharged through the air outlet at the top of the piston tube and the one-way assembly. Gas cannot enter the piston chamber inside the piston tube through the one-way assembly and the air outlet. Under pressure, the push plate cannot move the reminder rod away from the air outlet to reset under the action of the rubber rope. When the sealing ring ages after prolonged use and fails to provide an effective seal, it can no longer effectively block the air inlet, allowing gas to enter the piston chamber. At this point, the pressure inside the piston tube is balanced. Under the action of the rubber rope, the push plate moves the reminder rod away from the air inlet, promptly alerting the operator to the aging of the sealing ring and its need for replacement. This prevents steam leakage and insufficient hot-pressing temperature caused by the sealing ring aging and failing to provide an effective seal. This effectively ensures the hot-pressing temperature is maintained.

[0007] Preferably, the one-way component includes an exhaust pipe, which is fixed to the top of the piston tube and its bottom is connected to the air outlet. A U-shaped tube is fixed and connected to the side of the exhaust pipe. A fixing block is fixed on the inner wall of the exhaust pipe, and a stop block is connected to the piston on the inner wall of the exhaust pipe. When gas enters from the bottom of the exhaust pipe, the gas pushes the stop block upward a certain distance. When the stop block cannot block the U-shaped tube, the gas can be discharged through the U-shaped tube and the exhaust pipe. When gas enters from the top of the exhaust pipe, the stop block blocks the U-shaped tube and the exhaust pipe, preventing the gas from passing through. Thus, the gas can only be discharged from the piston tube and cannot enter the piston tube through the exhaust pipe.

[0008] Preferably, the connector is located on the top of the hot press plate, the mounting head is connected to the secondary circulation pipe through a sealing bearing, the mounting head and the connector are threaded together, and the sealing ring is placed inside the connector. The sealing bearing ensures the seal between the mounting head and the secondary circulation pipe without affecting the normal rotation of the mounting head. After the mounting head and the connector are threaded together and tightened, the mounting head and the connector squeeze the sealing ring, thereby achieving a sealing operation and effectively preventing steam leakage.

[0009] Preferably, the top of the mounting head is provided with an air hole, the position of which corresponds to the air inlet. When the sealing ring ages and cannot seal effectively, steam can enter the piston tube through the air hole and the air inlet.

[0010] Compared with the prior art, this utility model provides a secondary circulation pipeline structure for improving hot-pressing temperature, which has the following beneficial effects:

[0011] 1. This secondary circulation pipeline structure for improving hot pressing temperature, through the setting of driven components and one-way components, ensures that when the sealing ring ages after prolonged use and fails to provide an effective seal, it can enter the piston chamber through the inlet. At this time, the pressure inside the piston tube is balanced. Under the action of the rubber rope, the push plate moves the reminder rod away from the inlet. The extension of the reminder rod can promptly remind the staff that the sealing ring is aging and needs to be replaced. This avoids the situation where the aging sealing ring fails to provide an effective seal, and the staff fails to notice in time, resulting in steam leakage and insufficient hot pressing temperature. This effectively ensures the hot pressing temperature.

[0012] 2. This secondary circulation pipeline structure, which improves the hot-pressing temperature, is simple to assemble. During installation, simply push the reminder rod, causing it to move the push plate closer to the air inlet. Since the air inlet is blocked, the gas can only be discharged through the air outlet at the top of the piston tube and the one-way component. However, the gas cannot enter the piston chamber inside the piston tube through the one-way component and the air outlet. Under pressure, the push plate cannot move the reminder rod away from the air outlet to reset under the action of the rubber rope. When the sealing ring ages and cannot seal, the gas can enter the air inlet, thus triggering the system. It is easy to use. Attached Figure Description

[0019] like Figures 1-5 As shown, this utility model provides a technical solution: a secondary circulation pipeline structure for improving hot pressing temperature, including a secondary circulation pipeline 2 disposed on the top of the hot pressing plate 1, and a sealing mechanism 3 disposed on the secondary circulation pipeline 2 and the hot pressing plate 1. The sealing mechanism 3 is composed of a connector 31, a mounting head 32, a sealing bearing 33 and a sealing ring 34. The top of the mounting head 32 is provided with a driven component 4 for alerting workers of leaks.

[0020] The driven assembly 4 includes a piston tube 41, which is fixed to the top of the mounting head 32. A piston chamber 42 is provided inside the piston tube 41. An air outlet 43 is provided at the top of the piston tube 41, and an air inlet 44 is provided at the bottom. A push plate 45 is connected to the piston inside the piston tube 41. A rubber rope 46 is fixed to the side of the push plate 45 away from the air inlet 44. The end of the rubber rope 46 away from the push plate 45 is fixed to the inner wall of the piston chamber 42. A reminder rod is fixed to the side of the push plate 45 near the rubber rope 46. 47. The reminder rod 47 passes through the piston tube 41 and is connected to the piston of the piston tube 41. The top of the piston tube 41 is provided with a one-way component 5 for only air output. The piston tube 41 is connected to the mounting head 32 through the air inlet 44 at the bottom. When the secondary circulation pipe 2 is installed on the hot press plate 1 through the mounting sealing mechanism 3, the sealing ring 34 blocks the air inlet 44 at the bottom of the piston tube 41. At this time, simply push the reminder rod 47, so that the reminder rod 47 drives the push plate 45 to move towards the side closer to the air inlet 44. When blocked, gas can only be discharged through the outlet 43 at the top of the piston tube 41 and the one-way component 5. However, the gas cannot enter the piston chamber 42 inside the piston tube 41 through the one-way component 5 and the outlet 43. Under pressure, the push plate 45 cannot move the reminder rod 47 away from the outlet 43 under the action of the rubber rope 46. When the sealing ring 34 ages after long-term use and fails to provide an effective seal, the sealing ring 34 can no longer effectively block the inlet 44. Gas can then enter the piston chamber 42 through the inlet 44. At this time, the pressure inside the piston tube 41 is balanced. Under the action of the rubber rope 46, the push plate 45 moves the reminder rod 47 away from the inlet 44, which can promptly remind the staff that the sealing ring 34 is aging and needs to be replaced. This avoids the situation where the sealing ring 34 ages and fails to provide an effective seal, and the staff fails to notice in time, resulting in steam leakage and insufficient hot pressing temperature. This effectively ensures the hot pressing temperature and indirectly improves the hot pressing temperature.

[0021] The one-way component 5 includes an exhaust pipe 51, which is fixed to the top of the piston tube 41 and its bottom is connected to the air outlet 43. A U-shaped tube 52 is fixed and connected to the side of the exhaust pipe 51. A fixing block 53 is fixed on the inner wall of the exhaust pipe 51, and a stop block 54 is connected to the piston on the inner wall of the exhaust pipe 51. When gas enters from the bottom of the exhaust pipe 51, the gas pushes the stop block 54 to move upward a certain distance. When the stop block 54 cannot block the U-shaped tube 52, the gas can be discharged through the U-shaped tube 52 and the exhaust pipe 51. When gas enters from the top of the exhaust pipe 51, the stop block 54 blocks the U-shaped tube 52 and the exhaust pipe 51, preventing the gas from passing through. Thus, the gas can only be discharged from the piston tube 41 and cannot enter the piston tube 41 through the exhaust pipe 51.

[0022] The connector 31 is located on the top of the hot press plate 1. The mounting head 32 is connected to the secondary circulation pipe 2 through the sealing bearing 33. The mounting head 32 and the connector 31 are threaded together. The sealing ring 34 is placed inside the connector 31. The sealing bearing 33 ensures the seal between the mounting head 32 and the secondary circulation pipe 2 without affecting the normal rotation of the mounting head 32. After the mounting head 32 and the connector 31 are threaded together and tightened, the mounting head 32 and the connector 31 compress the sealing ring 34, thereby achieving a sealing operation and effectively preventing steam leakage.

[0023] The top of the mounting head 32 has an air hole 6, which is located opposite to the air inlet 44. When the sealing ring 34 ages and cannot seal effectively, steam can enter the piston tube 41 through the air hole 6 and the air inlet 44.

[0024] Based on the above implementation method, after the mounting head 32 and the connecting head 31 are threaded together and tightened, the mounting head 32 and the connecting head 31 compress the sealing ring 34, thereby achieving a sealing operation and effectively preventing steam leakage. After installation, the sealing ring 34 blocks the air hole 6 and the air inlet 44, pushing the reminder rod 47, causing the reminder rod 47 to drive the push plate 45 to move towards the side closer to the air inlet 44. Since the air inlet 44 is blocked, the gas can only be discharged through the air outlet 43 at the top of the piston tube 41 and the one-way component 5. However, the gas cannot enter the piston chamber 42 inside the piston tube 41 through the one-way component 5 and the air outlet 43. Under the influence of pressure, the push plate 45 cannot be driven by the rubber rope 46. The reminder rod 47 moves to the side away from the air outlet 43 to reset. When the sealing ring 34 ages after long-term use and fails to provide an effective seal, it can no longer effectively block the air inlet 44. Gas can then enter the piston chamber 42 through the air inlet 44. At this time, the pressure inside the piston tube 41 is balanced. Under the action of the rubber rope 46, the push plate 45 drives the reminder rod 47 to move to the side away from the air inlet 44. This can promptly remind the staff that the sealing ring 34 is aging and needs to be replaced. This avoids the situation where the sealing ring 34 ages and fails to provide an effective seal, and the staff fails to notice in time, resulting in steam leakage and insufficient hot pressing temperature. This effectively ensures the hot pressing temperature.

[0025] The staff only needs to unscrew the mounting head 32 and replace the sealing ring 34.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
