Description

Technical Field

[0001] The present application relates to the technical field of cooling towers, and in particular to a cooling and shaping device for a PET foam board production line. Background Art

[0002] At present, foam boards are used in people's daily lives and can be used as insulation or packaging materials, providing convenience for people's lives.

[0003] During the production process, the foam board undergoes processes such as foaming and molding, and its internal structure is in a high-temperature unstable state. If the heat is not dissipated in time, the heat will accumulate inside the foam board, which will change the physical properties of the material and cause deformation and warping of the foam board. After the foam board is processed, it will be sent to the cooling tower, where the heat will be dissipated, and then it will be transported to the subsequent processing site.

[0004] During the actual processing of foam boards, the foam boards are cooled naturally during transportation, or fans are installed for air cooling. The cooling tower provides a transportation method and cooling space for the foam boards, so that the foam boards can be cooled during transportation. However, conventional cooling towers only provide temporary cooling storage space for the foam boards, and are unable to adjust the position of the foam boards that are cooled by air. The foam boards are cooled by air on one side, resulting in uneven cooling of the foam boards. Summary of the invention

[0005] In order to evenly cool the foam board, the present application provides a cooling and shaping device for a PET foam board production line.

[0006] The present application provides a cooling and shaping device for a PET foam board production line, which adopts the following technical solution:

[0007] A cooling and shaping device for a PET foam board production line comprises a cooling shell, on which a transverse tube, a heat sink, an internal tube and an air supply pipe are arranged, the transverse tube is arranged horizontally and slidably on the outer wall of the cooling shell, the sliding path of the transverse tube is in the shape of a circular runway on the vertical plane, the heat sink is fixed on the transverse tube for receiving the foam board, and air holes are provided on the side wall of the heat sink close to the foam board; a cavity is provided inside the cooling shell, one end of the internal tube is connected to the inside of the transverse tube, and the other end passes through the cavity, and the internal tube follows the transverse tube and is slidably arranged relative to the cooling shell; the heat sink, the transverse tube and the internal tube form a ventilation path from the cavity to the air hole; the cooling shell is connected to the air supply pipe, and the air supply pipe is used to be connected to an external air pump.

[0008] By adopting the above technical solution, the foam board is transported to the cooling shell, the heat sink fork lifts the foam board and starts to move on the cooling shell, and finally is transported from one side of the cooling shell to the other side. It is flipped during the transportation process, and the fans in the factory are fully utilized to evenly cool both sides of the foam board. At the same time, the air supply pipe is connected to the external air pump, and the foam board on the heat sink is evacuated through the ventilation path. The suction force generated allows the foam board to be stably placed on the heat sink, and part of the heat on the foam board can also be extracted, which also has a cooling effect.

[0009] Optionally, a special-shaped gear and a baffle are provided on the inner tube, a first through hole is formed on the special-shaped gear, a second through hole is formed on the baffle, the side wall of the special-shaped gear close to the baffle is rotatably connected to the baffle, the baffle and the special-shaped gear separate the inner tube into two parts, the side wall of the baffle close to the inner tube is fixed to the inner tube, the side wall of the special-shaped gear close to the inner tube is rotatably connected to the inner tube, and during the rotation of the special-shaped gear relative to the baffle and the inner tube, there is an overlapping time period between the first through hole and the second through hole; a rack is fixed on the outer wall of the cooling shell, the rack is vertical, and the rack is meshed with the special-shaped gear.

[0010] By adopting the above technical solution, the air supply pipe is connected to the external air pump, and the foam board on the heat sink is evacuated through the ventilation path. The suction force generated enables the foam board to be stably placed on the heat sink. When the foam board is turned over and needs to be transported to the next process, the special-shaped gear engages with the rack, and the first through hole and the second through hole begin to be misaligned. Until the heat sink moves to a horizontal state again, the first through hole and the second through hole are completely misaligned. At this time, suction force is no longer generated at the air holes, which facilitates the foam board on the heat sink to be separated from the heat sink.

[0011] Optionally, it also includes a first horizontal conveyor belt, which is placed beside the cooling shell and located on the side of the cooling shell away from the rack. The first conveyor belt is provided with a first notch, and the first notch is used for the heat dissipation rack to pass through the first horizontal conveyor belt in a vertical direction.

[0012] By adopting the above technical solution, the first horizontal conveyor belt conveys the foam board horizontally to the heat dissipation rack. The setting of the first notch enables the heat dissipation rack to stay in a horizontal state on the first conveyor belt, and at this time, the bottom inner wall of the heat dissipation rack is horizontal with the top belt surface of the first horizontal conveyor belt, so that the foam board can directly slide into the heat dissipation rack and be forked by the heat dissipation rack.

[0014] By adopting the above technical solution, after the heat dissipation rack forks the foam board and transports it from one side of the cooling shell to the other side, until the heat dissipation rack is horizontal again, the foam board on the heat dissipation rack falls on the translation belt, and is then transported by the translation belt in a direction away from the cooling shell, thereby achieving the detachment of the foam board from the heat dissipation rack.

[0015] Optionally, a first bolt and a second bolt are threadedly connected on the translation frame, and the first bolt passes through the translation roller. The first bolt is rotationally connected to the translation roller, that is, the first bolt rotates relative to the translation roller; a nut is threadedly connected on the second bolt, and the nut of the second bolt itself abuts against the top of the translation motor, and the nut abuts against the bottom of the translation motor.

[0016] By adopting the above technical solution, the positions of the translation motor and the translation roller in the vertical direction are adjusted by rotating the first bolt and the second bolt, so that the translation roller pulls the belt surface of the translation belt to achieve tension or relaxation of the belt surface.

[0017] Optionally, a tension wheel is rotatably provided on the translation frame, and two tension wheels are provided under the same translation belt and are distributed on both sides of the translation roller. The two tension wheels cooperate with the translation roller to adjust the tension of the translation belt.

[0018] By adopting the above technical solution, the two tensioning wheels cooperate with the translation roller to further adjust the tension of the belt surface of the translation belt.

[0019] Optionally, it also includes a flip frame, which is located on the side of the translation frame away from the cooling shell, and is provided with a flip motor, a rotating rod, a turntable and a flip rod. The flip motor is fixed on the top of the flip frame, and the output end of the flip motor is fixedly connected to one end of the rotating rod. The rotating rod is rotatably set on the flip frame and passes through the center of the turntable. The turntable is fixedly connected to the rotating rod, and a plurality of flip rods are provided. One end of the flip rod is fixed on the circumferential side wall of the turntable, and adjacent flip rods are spaced apart along the circumferential side wall of the turntable.

[0020] By adopting the above technical solution, the translation belt transports the foam board to between adjacent flip rods, the flip motor is started to drive the rotating rod to rotate, and the flip rod is driven to rotate by the turntable, and the two flip rods flip the foam board, so that the foam board is turned over by the heat dissipation rack and then turned over again by the flip rod, so that the foam board returns to its original posture.

[0021] Optionally, a linkage belt is provided on the cooling shell, which divides the cooling shell into two parts. The sliding path of the inner tube on the cooling shell is the length of the linkage belt. The linkage belt is rotatably arranged on the cooling shell, that is, the linkage belt rotates relative to the cooling shell, and the inner tube passes through the linkage belt.

[0022] By adopting the above technical solution, the setting of the linkage belt plays a role in shielding the sliding path of the inner pipe on the cooling shell, and also plays a role in sealing the internal space of the cooling shell.

[0023] Optionally, it also includes a second horizontal conveyor belt, which is located on the side of the flip frame away from the translation frame. The second horizontal conveyor belt is arranged parallel to the first conveyor belt. The second horizontal conveyor belt is provided with a second notch, and the second notch is used for the flip rod to pass through the second horizontal conveyor belt in the vertical direction.

[0024] By adopting the above technical solution, the second horizontal conveyor belt completes the final transportation of the foam board, so that the foam board is transported away in the same state as it was transported in. The second notch ensures the smooth transportation of the foam board and reduces the floor space of the entire cooling tower system, making the related equipment compact.

[0025] Optionally, a driving assembly is provided on the outer wall of the cooling shell, and the driving assembly includes a driving motor, a sprocket and a chain. Two sprockets are provided and both are rotatably arranged on the outer wall of the cooling shell. The two sprockets are arranged in a vertical direction, and the chain ring is sleeved on the two sprockets. The driving motor is fixed on the cooling shell to drive one of the sprockets to rotate; the end of the cross tube is fixed on the chain.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The setting of cooling shell and heat dissipation rack enables the foam board to be turned over during transportation, making full use of the fans in the factory so that both sides of the foam board can be cooled evenly;

[0028] 2. The air supply pipe is connected to an external air pump, and air is extracted from the foam board on the heat sink through the ventilation path.

[0029] 3. The rack, special-shaped gear and baffle are arranged so that after the foam board is turned over and before it needs to be transported to the next process, the special-shaped gear is engaged with the rack, and the first through hole and the second through hole begin to be misaligned until the heat sink moves to a horizontal state again, and the first through hole and the second through hole are completely misaligned. At this time, suction is no longer generated at the air holes, which facilitates the foam board on the heat sink to be separated from the heat sink. BRIEF DESCRIPTION OF THE DRAWINGS
