Technical Field

[0001] The utility model relates to the technical field of vacuum plastic absorption, in particular to a double-station high-speed vacuum plastic absorption forming machine. Background Art

[0002] Vacuum forming is often called blister forming. It is a plastic processing technology. The main principle is to heat and soften the flat plastic hard sheet, and then use vacuum to absorb it on the surface of the mold fixing plate, and then cool it to form. It is widely used in plastic packaging, lighting, advertising, decoration and other industries. Vacuum blister forming machine is a common plastic forming processing equipment. It heats and softens the plastic sheet, then places it on a mold, and uses vacuum suction to make it close to the mold surface to form the desired shape.

[0003] A Chinese patent with authorization announcement number CN218256721U discloses a double-station plastic plate vacuum forming machine that can quickly demold. A driving motor is used to drive the transmission rod to rotate, so that the contact plate rotates with the transmission rod located at the axis. The elasticity of the telescopic spring can be used to push the transmission plate up and down, driving the plastic plate to shake up and down, so that the plastic plate and the vacuum template are separated from each other for demolding. At the same time, the cooling air outlet is used to blow air to cool the plastic plate, which facilitates the demolding work and improves practicality.

[0004] However, the molding machine mentioned above is equipped with double stations, and two sets of driving motors are used to drive the double stations to move respectively. When the double stations work continuously, two motors need to run synchronously, one motor moves the station seat in the heating box out, and the other motor moves the station seat outside into the heating box, resulting in a higher overall power cost.

[0017] Embodiment 1

[0018] like Figure 1-Figure 3 As shown, a double-station high-speed vacuum plastic forming machine proposed by the utility model includes a chassis 1, a groove 2 is opened on the upper end surface of the chassis 1, guide pillars 3 are arranged on both sides of the inner wall of the groove 2, a moving plate 4 is slidably arranged between the two guide pillars 3, and a station seat 5 is symmetrically arranged on the top of the moving plate 4, a reciprocating component for driving the moving plate 4 to move left and right is arranged at one end of the groove 2, and an intermittent driving part cooperating with the reciprocating component is arranged on one side of the reciprocating component, a heating box 6 is arranged on the chassis 1, and inlet and outlet curtains 7 are arranged on both sides of the heating box 6, a top plate 8 is arranged on the top of the heating box 6, and air cooling components are arranged on both sides of the top plate 8.

[0019] Among them, the reciprocating component includes a rotating shaft 9, a turntable 10 and a pull rod 11. The rotating shaft 9 is rotatably set in the groove 2 through a bearing. The turntable 10 is connected to the top of the rotating shaft 9. The pull rod 11 is rotatably set at the eccentric part of the top of the turntable 10. One end of the pull rod 11 is rotatably connected to the bottom of the moving seat.

[0020] Among them, the intermittent driving part includes a reduction motor 12, a special-shaped gear 13, a special-shaped toothed disc 14, a push column 15 and a push plate 16. The reduction motor 12 is installed at the bottom of the inner wall of the groove 2, and the output end of the reduction motor 12 is connected to the special-shaped toothed disc 14. The upper end surface of the special-shaped toothed disc 14 is provided with a push column 15. The special-shaped gear 13 is installed in the middle of the rotating shaft 9, and push plates 16 are symmetrically arranged on both sides of the upper end surface of the special-shaped gear 13.

[0021] Furthermore, both sides of the special-shaped gear 13 are provided with rows of teeth a17 corresponding to each other, and two push plates 16 are respectively arranged at the two ends between the two groups of rows of teeth a17. The outer side of the special-shaped toothed disc 14 is provided with a row of teeth b18, and the push column 15 is close to one end of the row of teeth b18. When the special-shaped toothed disc 14 rotates to a certain position under the driving action of the reduction motor 12, the push column 15 on its upper end surface will approach the push plate 16 during the rotation process and apply a driving force to the push plate 16. Under the action of the driving force, the push plate 16 drives the special-shaped gear 13a to drive the rotating shaft 9 to rotate. During the rotation process, the row of teeth a17 on one side of the special-shaped gear 13 is in a meshing state with the row of teeth b18 of the special-shaped toothed disc 14. When the special-shaped gear 13 rotates to the end of its row of teeth a17 section, it stops rotating until the push column 15 applies a driving force to it again.

[0022] The working principle of the utility model is as follows: when in use, the workpiece to be formed is placed on the outer workstation 5, the reduction motor 12 is started, and the reduction motor 12 drives the special-shaped toothed disc 14 to rotate. When the special-shaped toothed disc 14 rotates to a certain position under the driving action of the reduction motor 12, the push column 15 on its upper end surface will approach the push plate 16 during the rotation process and apply a driving force to the push plate 16. Under the action of the driving force, the push plate 16 drives the special-shaped gear 13a to drive the rotating shaft 9 to rotate. During the rotation process, the row of teeth a17 on one side of the special-shaped gear 13 is in a meshing state with the row of teeth b18 of the special-shaped toothed disc 14. When the special-shaped gear 13 rotates to the end of its row of teeth a17 section, that is, after rotating 180 degrees, it will stop rotating. During the rotation, the rotating disk 10 is driven by the rotating shaft 9 to rotate 180 degrees synchronously. When the rotating disk 10 rotates, the movable plate 4 is driven by the pull rod 11 to move along the guide column 3, so that the outer station seat 5 enters the heating box 6 for molding operation, and the station seat 5 in the heating box 6 is moved out from the inside, and the staff loads and unloads the workpiece. With the continuous driving of the reduction motor 12, the special-shaped toothed disk 14 will be driven to rotate again for one circle, and then the rotating disk 10 will be driven to rotate 180 degrees in the same direction. During the rotation, the movable plate 4 is driven to reset, so that the two station seats 5 can work continuously as a whole. During the molding process of the station seat 5 on one side, the station seat 5 on the other side is loading and unloading, and the overall work efficiency is relatively high.

[0023] Embodiment 2

[0024] like Figure 1-Figure 3 As shown, the utility model proposes a double-station high-speed vacuum plastic forming machine. On the basis of the above embodiment, this embodiment also discloses in detail the specific components of the air cooling assembly, which includes an air cooler 19 and an air guide hood 20. The air cooler 19 is provided in two groups, and the air outlet ends of the two groups of air coolers 19 are connected to the air guide hood 20 located below the top plate 8.

[0025] Furthermore, pressure switches 21 are provided at the tops of both ends of the inner wall of the groove 2 , and two groups of pressure switches 21 are respectively controlled and connected to the two groups of cooling fans 19 .

[0026] In this embodiment, when the movable plate 4 drives the formed work station seat 5 to move out of the heating box 6, one end of the movable plate 4 will squeeze the pressure switch 21, and the pressure switch 21 will turn on the air cooler 19 above it to perform air cooling operation on the workpiece on the work station seat 5. When the movable plate 4 enters the heating box 6, its end is away from the pressure switch 21, and the air cooler 19 stops working, which effectively avoids the air cooler 19 from working for a long time and reduces electricity costs.

[0027] 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.
