Description

Technical Field

[0001] The utility model relates to the technical field of plastic suction machines, in particular to an automatic positive and negative pressure plastic suction forming machine. Background Art

[0002] The positive and negative pressure blister machine transmits the heated airflow to every part of the workpiece through positive pressure. The airflow takes on the temperature when it is pressurized, and the transfer is more in place, making it difficult for the workpiece to be demolded. Existing positive and negative pressure blister machines are usually not equipped with a scrap collection structure, and the scraps are scattered and piled up on the discharge side.

[0003] The Chinese patent with the authorization announcement number CN217454992U discloses a fully automatic positive and negative pressure blister forming device, which belongs to the technical field of blister machines, including a blister machine, a raw material conveying roller is arranged on the left side of the blister machine, a punching and cutting machine is arranged on the right side of the blister machine, and a waste material winding roller is arranged on the right side of the punching and cutting machine. The beneficial effect of the utility model is that the waste material winding roller can pull the plastic film on the surface of the raw material conveying roller for transmission, and the plastic film will be located at the blister machine and will be pressed by the heated negative pressure plate for blister forming, and the blister formed plastic film will continue to move to the punching and cutting machine, and the punching and cutting machine will cut the formed finished product from the plastic film, and the discarded plastic scraps will continue to be wound by the waste material winding roller, without the need for manual sorting of the discarded scraps, and the finished plastic parts on the surface of the punching and cutting machine can be adsorbed and unloaded by the set liftable and rotary vacuum suction plate, and the blister forming device has a high degree of automation, and loading and unloading does not require manual operation, and the efficiency is effectively improved.

[0004] However, the device still has some shortcomings: after the molding material is cut, the raw material transportation needs to be suspended, the cut material must be sucked out first and then the transmission is resumed. This action reduces the overall processing efficiency of the device, and when the scrap material is wound to a certain extent, it is troublesome to replace the winding roller. Utility Model Content

DETAILED DESCRIPTION

[0022] Embodiment 1

[0023] like Figure 1-4 As shown, the utility model provides an automatic positive and negative pressure plastic forming machine, which includes a frame 1, a guide roller 16 and a rotating shaft 19.

[0024] The frame 1 is provided with a guide frame 2, a blister machine 3, a bracket A4, a bracket B10 and a vertical plate 15 arranged in sequence along the feeding direction to the discharging direction. A cutter 5 is arranged at the bottom of the upper end of the bracket A4, a through hole A101 is arranged on the frame 1, a frame 6 is arranged inside the through hole A101 and is slidably connected thereto, a negative pressure support seat 7 is rotatably arranged inside the frame 6, a motor A8 is arranged on the frame 6 to drive the negative pressure support seat 7 to rotate, a hydraulic cylinder A9 is arranged on the bracket A4 to drive the frame 6 to rise and fall, and a material receiving assembly for receiving materials is arranged on the frame 1. An extrusion assembly is arranged inside the bracket B10. The extrusion assembly includes a lower extrusion roller 11 and an upper extrusion roller 13. A movable frame 12 is arranged inside the bracket B10 and is slidably connected thereto, and both ends of the upper extrusion roller 13 are rotatably connected to the corresponding ends of the movable frame 12, and a hydraulic cylinder B14 is arranged on the bracket B10 to drive the movable frame 12 to rise and fall. A transverse plate 24 is arranged below the operating table of the frame 1, fixed blocks are symmetrically arranged on the transverse plate 24, transmission rollers are arranged between the fixed blocks on both sides, the transmission rollers on both sides are connected by a conveyor belt 25, and a motor C for driving one of the transmission rollers to rotate is arranged on the fixed block.

[0025] The guide roller 16 is rotatably arranged between the vertical plates 15 on both sides, and a movable plate 17 rotatably connected thereto is arranged on one vertical plate 15, and a locking member 18 is arranged on the movable plate 17 to limit the relative rotation between the movable plate 17 and the vertical plate 15. The rotating shaft 19 is rotatably arranged on the movable plate 17, and a motor B20 for driving the rotating shaft 19 to rotate is arranged on the movable plate 17. A slide groove 191 and a through hole B192 connected to the slide groove 191 are arranged in the rotating shaft 19, and sliders 21 are arranged in the slide grooves 191 on both sides, and two blocks 22 are symmetrically and elastically slidably arranged in the sliders 21, and each block 22 passes through the corresponding side through hole B192, and a bidirectional module 23 for driving the sliders 21 on both sides to slide is arranged in the rotating shaft 19. Flexible anti-skid pads are arranged on the sides of the blocks 22 on both sides that are close to each other, and supporting feet are arranged at the bottom of the frame 1, and anti-vibration anti-skid pads are arranged at the bottom of the supporting feet.

[0026] In this embodiment, the scrap winding roller is installed before processing. At this time, the rotation restriction of the movable plate 17 is first released, and the spacing between the two side blocks 22 is adjusted to be maximized. Then the winding roller is put on the rotating shaft 19, and the two side blocks 22 are adjusted to press it from both sides of the winding roller. The movable plate 17 is rotated and locked, and the motor B20 is used to drive the rotating shaft 19 and the winding roller to rotate, thereby pulling the plastic sheet to move. During the processing of the winding roller, the front section of the plastic sheet of the scrap material slides along the upper end of the inner roller group of the guide frame 2 to reach the processing station of the blister machine 3. The upper and lower mold seats of the blister machine are closed to start vacuum blister molding. After molding, the mold is automatically opened. The molding material is still integrally connected to the plastic sheet at this time. The molding material is transported to the bottom of the cutter 5, and the hydraulic cylinder A9 pulls up the frame 6 and the negative pressure support seat 7. The protruding part of the molding material slides into the negative pressure support seat 7. As the negative pressure support seat 7 slides up and presses against the cutter 5, the molding material is directly cut off, and then the frame 6 slides down and rotates during the sliding process to make the molding material face downward. The negative pressure support seat 7 places the molding material on the conveyor belt 25, slides up, and rotates to reset. In this cycle, the molding material is automatically stacked layer by layer. This structure is efficient and safer.

[0027] Embodiment 2

[0028] like Figure 1 As shown, the automatic positive and negative pressure blister forming machine proposed by the present invention, compared with the first embodiment, the negative pressure support seat 7 includes a front and back side, and the front and back side structures of the negative pressure support seat 7 are the same.

[0029] In this embodiment, after the negative pressure support 7 rotates 180 degrees, it descends to discharge the material. After the discharge is completed, there is no need to rotate and reset. The molding material can be directly lifted by turning over, thereby improving the processing efficiency.

[0030] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
