Description

Technical Field

[0001] The present application relates to the technical field of blister machines, and in particular to a baking blister mechanism. Background Art

[0002] Blister forming is a plastic processing technology. The main principle is to heat and soften the flat plastic sheet, then use vacuum adsorption to the mold surface, and then cool it to form it. Depending on the mold used in the blister machine, the blister process can be divided into male vacuum forming and female vacuum forming. Among them, the male vacuum forming process is widely used in plastic packaging, decoration and other industries.

[0003] In the traditional blister process, after the sheet is clamped in the frame, the sheet is heated to soften by moving the baking mechanism, and then the sheet is lifted up by the workpiece on it by moving the negative pressure plate, and the air between the workpiece and the sheet is extracted by the negative pressure plate to adsorb the sheet onto the workpiece. However, in the existing blister machines, the baking mechanism is often located on the side of the sheet away from the workpiece, that is, when the sheet is baked, the side of the sheet where the heat melts is away from the workpiece, resulting in poor bonding effect after the sheet is adsorbed on the surface of the workpiece. In order to reasonably improve this problem, the present application proposes a baking blister mechanism. Summary of the Invention

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0027] like Figures 1-4 As shown, a baking blister mechanism proposed in one embodiment of the present application includes:

[0028] The bottom plate 1 is connected to a bracket 2 on the top. The bracket 2 is composed of a plurality of support rods 15 arranged symmetrically. A frame 3 is installed on the bracket 2, and the sheet can be fixed by the frame 3;

[0029] The workpiece is placed on the top of the loading plate 4, which slides with the bracket 2 and overlaps with the bottom of the frame 3. A driving member 5 is provided on the bottom plate 1, which can drive the loading plate 4 to slide. The driving member 5 includes a screw 501 and a motor 502. The axis of the screw 501 is perpendicular to the bottom plate 1 and rotates with the bottom plate 1. The motor 502 can drive the screw 501 to rotate, thereby driving the loading plate 4 to slide vertically. When the loading plate 4 slides upward and conflicts with the bottom of the frame 3, the workpiece can lift the sheet;

[0030] Two guide rails 6 are symmetrically arranged on both sides of the bracket 2. Both guide rails 6 are parallel to the bottom plate 1. A movable plate 7 is provided at the bottom of the frame 3. The movable plate 7 is made of high-temperature and high-pressure resistant resin, glass fiber alkali-free cloth and composite reinforcement material through mold lamination. It has the advantages of high temperature resistance and heat insulation, and is slidably matched with the two guide rails 6. The sliding direction of the movable plate 7 is perpendicular to the sliding direction of the carrier plate 4. A plurality of baking tubes 8 are provided on the top of the movable plate 7. The baking tubes 8 can be used to bake the sheet material to soften it and slightly melt it.

[0031] The driving mechanism 9 can drive the movable plate 7 to slide. When the movable plate 7 slides to the bottom of the frame 3, the storage plate is located at the bottom of the movable plate 7. At this time, the sheet material can be baked through the baking tube 8. When baking is completed, the movable plate 7 is driven to slide by the driving mechanism 9, and then the loading plate 4 can be driven to slide upward by the driving member 5;

[0032] The blister 10 is provided on the bottom plate 1 and can be used to perform blister processing on the sheet. When the workpiece lifts the sheet, the blister 10 can extract the air between the carrier plate 4 and the frame 3 so that the sheet can be attached to the workpiece.

[0033] The present application adopts a coordinated design of a guide rail 6 and a movable plate 7, and sets the baking tube 8 on the side where the sheet is bonded to the workpiece. When baking is completed, the side of the sheet where the heat is melted can be adsorbed on the surface of the workpiece to improve the bonding effect between the sheet and the workpiece.

[0034] like Figure 2 and Figure 3 As shown, in some embodiments, there are two movable plates 7, which are symmetrically arranged on the guide rail 6. The driving mechanism 9 can drive the two movable plates 7 to move relative to or opposite to each other, so that the two movable plates 7 can slide to both sides of the loading plate 4 at the same time. By driving the two movable plates 7 to slide at the same time, the time spent on their travel can be reduced, which can effectively improve production efficiency.

[0035] like Figure 1 and Figure 2 As shown, in some embodiments, the blister 10 includes a vacuum pump 1001 installed on the top of the base plate 1, a box body 1002 is connected to the bottom of the carrier plate 4, a plurality of vents 1003 are provided on the carrier plate 4, and the suction end of the vacuum pump 1001 is connected to the inside of the box body 1002, and the two are connected by a hose 17. When the vacuum pump 1001 is working, the air between the carrier plate 4 and the frame 3 can be extracted through the box body 1002 and the vents 1003, so that the sheet can fit the workpiece.

[0036] like Figure 1 and Figure 2 As shown, in some embodiments, a sealing gasket 11 is laid around the carrier plate 4. The sealing gasket 11 is a rubber gasket and overlaps with the frame 3. When the carrier plate 4 contacts the frame 3, the sealing gasket 11 can improve the tightness of the connection between the two, so as to facilitate the blister processing.

[0037] like Figure 1 、 Figure 2 and Figure 4As shown, in some embodiments, the driving mechanism 9 includes a first connecting block 901 provided on both sides of the carrier 4, the first connecting block 901 is installed on both sides of the box 1002, and the two movable plates 7 are connected to the second connecting block 902, the second connecting block 902 is located at the bottom of the movable plate 7, and the two second connecting blocks 902 are hinged to the first connecting block 901 through a hinge plate 903, there is an angle between the two hinge plates 903, and the length of the hinge plate 903 is greater than the stroke of the carrier 4. By adopting such a design, the carrier 4 and the movable plate 7 can be linked, that is, when the carrier 4 slides up, the first connecting block 901, the second connecting block 902 and the two hinge plates 903 cooperate with each other to drive the two movable plates 7 to move away from each other, and when the carrier 4 slides down, the two movable plates 7 can be driven to move relative to each other.

[0038] like Figure 2 and Figure 3 As shown, in some embodiments, a through groove 12 is provided on the movable plate 7, and the through groove 12 passes through the top and bottom sides of the movable plate 7. A plurality of baking tubes 8 are installed in the through groove 12, and a bellows 13 is installed at the bottom of the movable plate 7. The bellows 13 covers the bottom of the through groove 12, and a plurality of strip grooves 14 are linearly distributed on the top of the bellows 13. The two bellows 13 are connected to the air outlet end of the vacuum pump 1001. A connecting box 19 is installed on the top of the bottom plate 1 and is connected to the air outlet end of the vacuum pump 1001. The two bellows 13 are connected to both ends of the connecting box 19 through a rubber tube 18. When the vacuum pump 1001 is working, the air flow passes through the bellows 13 and the strip groove 14 to blow the baking tube 8 in the through groove 12, and blows the heat on the sheet. Compared with traditional heat radiation baking, this design has higher baking efficiency.

[0039] like Figure 2 and Figure 3 As shown, in some embodiments, the extending direction of the strip groove 14 is perpendicular to the axis of the baking tube 8. Such a design allows the airflow to fully contact the baking tube 8 when passing through the groove 12, thereby facilitating heating of the airflow.

[0040] like Figure 1 and Figure 2 As shown, in some embodiments, the frame 3 includes a fixed frame 301 and a movable frame 302. The fixed frame 301 is fixedly installed on the bracket 2, and the sheet is placed on the top of the fixed frame 301. The movable frame 302 is slidably arranged on the top of the fixed frame 301 and is in contact with the top of the fixed frame 301. The top of the guide rail 6 is vertically connected with a guide rod 16. The movable frame 302 is slidably installed on the guide rod 16. An electric push rod 303 is installed on the top of the base plate 1. The movable frame 302 is connected to the output end of the electric push rod 303. When the electric push rod 303 drives the movable frame 302 to move downward, the movable frame 302 cooperates with the fixed frame 301 to clamp and fix the sheet.

[0041] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
