The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] like Figures 1 to 7 As shown, a pressing structure of a pressing machine is characterized in that it comprises a workbench 1, a movable base 2 is provided on the upper side of the workbench 1, and a conveying guide rail 3 is provided on the movable base 2;

[0030] The conveying guide rail 3 is provided with a pressing adsorption plate 4, which is used to place the pressing film to be pressed, move the pressing film into the pressing mold 5, and move the pressed film out of the pressing mold 5 after pressing;

[0031] The pressing mold 5 includes a pressing upper mold and a pressing lower mold. The pressing lower mold is fixed on the upper side of the workbench 1, and the pressing upper mold is arranged on the upper side of the pressing upper mold through a bracket. The pressing upper mold moves up and down under the action of the pressing driving structure;

[0032] The height adjustment structure 6 is disposed between the movable base 2 and the workbench 1 and is used for adjusting the up and down movement of the movable base 2 .

[0033] The conveying guide rail 3 conveys the sheet-like upper film on the upper side of the pressing adsorption plate 4 to the position of the pressing mold 5. Under the action of the height adjustment structure 6, the conveying guide rail 3 and the pressing adsorption plate 4 are controlled to move up and down, so that the pressing adsorption plate 4 is placed on the upper side of the pressing upper mold. After the pressing is completed, the pressing adsorption plate 4 is conveyed out through the conveying guide rail 3, thereby realizing the pressing of the sheet-like upper film. The entire production process is fully automated, which greatly improves the production efficiency.

[0034] The conveying guide rail 3 is used to convey the pressing adsorption plate 4. At this time, in order to improve the pressing efficiency during the pressing process, in this embodiment, the conveying guide rail 3 is a double-layer guide rail structure with high and low distribution. The conveying guide rail 3 includes two side fixed brackets. The side of the side fixed bracket is provided with a first guide rail group 31 and a second guide rail group 32. The first guide rail group 31 is located at the upper side of the second guide rail group 32. The upper sides of the first guide rail group 31 and the second guide rail group 32 are respectively provided with a first pressing adsorption plate 41 and a second pressing adsorption plate 42. The double-layer guide rail structure arranged up and down is set, and the corresponding first pressing adsorption plate 41 and second pressing adsorption plate 42 are set. In this way, continuous feeding, pressing, and discharging processes can be realized during use, thereby further improving the working efficiency of the pressing mold 5, and then improving the overall production efficiency.

[0035] After the double-layer guide rail structure is set, in order to realize the independent control of the first guide rail group 31 and the second guide rail group 32, in this embodiment, the outer side of the side fixed bracket is respectively provided with a motor synchronous belt structure for controlling the first pressing adsorption plate 41 and the second pressing adsorption plate 42, which is used to control the first pressing adsorption plate 41 and the second pressing adsorption plate to move along the direction of the first guide rail group 31 and the second guide rail group 32. Through the independent motor synchronous belt structure, the first guide rail group 31 and the second guide rail group 32 are controlled respectively, so as to independently control the movement of the first pressing adsorption plate 41 and the second pressing adsorption plate 42, so that in the production process, the position of the first pressing adsorption plate 41 and the second pressing adsorption plate 42 can be better controlled, so that the first pressing adsorption plate 41 and the second pressing adsorption plate 42 can handle different processes.

[0036] Since a double-layer guide rail structure is provided, when the pressing adsorption plate 4 at the position of the double-layer guide rail structure is moved to the upper side of the pressing lower die, it is necessary to adjust the position height of the pressing adsorption plate 4 to move the pressing adsorption plate 4 to the upper side of the pressing lower die. Therefore, in this embodiment, the height adjustment structure 6 includes a guide rail 61 fixed on the upper side of the workbench 1, and a wedge block 62 is connected to the upper side of the guide rail 61 through a slider. The wedge block 62 is provided with different height surfaces. The lower side of the mobile base 2 is provided with a rolling wheel 63, and the rolling wheel 63 is set at the four corners of the mobile base 2. The rolling wheel 63 is rollingly set at the upper side of the wedge block 62. When the contact surface between the rolling wheel 63 and the wedge block 62 is located at different height positions of the wedge block 62, the height position of the mobile base 2 changes synchronously. Further, the wedge block 62 includes a horizontal surface and an inclined surface, and the horizontal surface is located at the highest position of the inclined surface. During the forward and backward relative movement between the wedge block 62 and the rolling wheel 63, the rolling wheel 63 contacts the upper side surface of the wedge block 62 at different positions. When the rolling wheel 63 moves on the inclined surface, the rolling wheel 63 is at different height positions, so that the double-layer guide rail structure and the corresponding pressing adsorption plate 4 move up and down, thereby controlling the corresponding pressing adsorption plate 4 to move to the pressing upper mold position. For the forward and backward relative movement between the wedge block 62 and the rolling wheel 63, in this embodiment, a height adjustment drive mechanism is provided, and a cylinder is used as the height adjustment drive mechanism. The cylinder is fixed on the upper side of the workbench 1, and the piston rod of the cylinder is connected to the movable base 2. At this time, since the movable base 2 will move up and down, a vertical groove is provided on the lower side of the movable base 2, and the piston rod is inserted into the vertical groove. In this way, during the up and down movement of the movable base 2, the piston rod is always in the vertical groove and drives the movable base 2 to move up and down.

[0037] After the lamination is completed, it is necessary to move the sheet-like upper film to be laminated on the upper side of another lamination adsorption plate 4 to the lamination upper mold. Therefore, it is necessary to first take out the laminated lamination film and the corresponding lamination adsorption plate 4 from the lamination upper mold. Therefore, in this embodiment, the lamination structure also includes a clamping structure 7. The lamination upper mold is laminated with the lamination lower mold. When the lamination film is completed and the mold is opened, the clamping structure 7 moves the lamination adsorption plate 4 and the upper lamination mold upward following the lamination upper mold. At this time, after the lamination is completed, the laminated lamination film and the corresponding lamination adsorption plate 4 are fixed to the lamination upper mold under the action of the clamping structure 7, and move upward following the lamination upper mold to open the mold. At the same time, the laminated lamination film is moved to the upper side of another conveying guide rail 3 and moved out of the lamination mold 5 position.

[0038] Specifically, the clamping structure 7 includes a clamping fixing plate 71, and the clamping fixing plate 71 is fixed on the outer side of the pressing upper mold. A vertical movable plate 72 is provided on the outer side of the clamping fixing plate 71 through a guide rail slider. A vertical cylinder 73 is also provided on the upper side of the clamping fixing plate 71. The vertical movable plate 72 moves up and down under the action of the vertical cylinder 73. The outer side of the vertical movable plate 72 is connected with a horizontal movable plate 74 through a guide rail slider. The vertical movable plate 72 is provided with a horizontal cylinder 75 for controlling the horizontal movement of the horizontal movable plate 74. The horizontal movable plate 74 is provided with a fixing hook 76. The fixing hooks 76 of the two clamping structures 7 are facing the center position of the pressing upper mold, and are used to move the pressing adsorption plate 4 upward after pressing. Under the action of the vertical cylinder 73 and the horizontal cylinder 75, the fixing hooks 76 located on both sides of the pressing adsorption plate 4 can fix the pressing adsorption plate 4, thereby realizing separation from the pressing lower mold, and then the pressing adsorption plate 4 is placed on the upper side of the conveying guide rail 3 by controlling the vertical cylinder 73 and the horizontal cylinder 75, thereby realizing the movement of the pressing adsorption plate 4.

[0039] The pressing adsorption plate 4 is used to carry the sheet-like upper film before and after pressing and move it. Therefore, in order to prevent the sheet-like upper film from moving on the upper side of the pressing adsorption plate 4 during the production process, in the present embodiment, the pressing adsorption plate 4 includes a pressing adsorption hole 411 on the upper surface, and the pressing adsorption plate 4 is provided with an adsorption groove connected to the pressing adsorption hole 411, and the adsorption groove includes a first area groove 412 and a second area groove 413 that are independent of each other, the first area groove 412 is rectangular as a whole, and the second area groove 413 is annular as a whole and is distributed on the outside of the first area groove 412, and the adsorption groove is connected to a vacuum pump, so that the pressing adsorption hole 411 The vacuum is realized at the position, and then the sheet-like upper film is adsorbed and fixed on the upper side of the pressed adsorption plate 4. At this time, in order to adapt to the production needs of different models, that is, the sheet-like upper films of different sizes, the adsorption groove includes a first area groove 412 and a second area groove 413 which are independent of each other, and the first area groove 412 is rectangular as a whole, and the second area groove 413 is annular as a whole, and is distributed on the outside of the first area groove 412. In this way, by separately controlling the first area groove 412 and the second area groove 413, the pressed adsorption holes 411 of different areas can be connected, thereby achieving adsorption effects of different areas, so as to target different models / sizes.

[0040] During the lamination process, in order to prevent the sheet-like upper film from deforming during the lamination process, in the present embodiment, the lamination upper mold and the lamination lower mold are provided with vacuum adsorption holes, and the vacuum adsorption holes are connected to the vacuum pump through a solenoid valve. At this time, after the lamination adsorption plate 4 moves to the upper position of the lamination lower mold, the lamination adsorption plate 4 is connected with the vacuum adsorption hole at the lower position, so that the upper and lower sides of the sheet-like upper film are both provided with holes with vacuum adsorption. During the lamination process, the air at the upper and lower positions of the sheet-like upper film can be discharged, so as to ensure the flatness of the pressed film obtained by lamination. At the same time, when taking out the pressed film, it can be avoided that the pressing upper mold and the pressed film are stuck to the lower side position of the pressing mold 5 due to the negative pressure between the two after lamination.

[0041] In order to prevent the sheet-like upper film from being damaged by contact with the mold during the lamination process, in this embodiment, the side plate of the lamination upper mold is provided with a paper clamping structure 8, which includes fixed shafts 81 at both sides of the lamination upper mold, the fixed shafts 81 are rotatably arranged on the outside of the lamination upper mold, the fixed shafts 81 are provided with a fixing groove, and a paper is provided between the fixing grooves of the two fixed shafts 81, and the paper is attached to the lower side of the lamination upper mold. The two ends of the paper are respectively clamped in the fixing grooves of the two fixed shafts 81, and then the fixed shafts 81 are rotated to tighten the paper. At this time, the paper is located at the lower side of the lamination mold 5. Therefore, when the paper is tightened, the paper is tightly attached to the lower side of the lamination upper mold, which can not only protect the sheet-like upper film, but also prevent the lamination upper mold and the lamination film from being attached to the lower side of the lamination mold 5 due to negative pressure when the lamination film is taken out.

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
