DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] A vacuum laminating machine provided by the present invention comprises a workbench 1, a film barrel 2, a film clamping frame 3 and a heating box 4, wherein the film barrel 2 is provided on the left side of the upper surface of the workbench 1, the film barrel 2 is provided on the right side of the film clamping frame 3, and the heating box 4 is provided on the right side of the film clamping frame 3;

[0029] The film clamping frame 3 includes a first connecting rod 31, a first rectangular block 32, a rotating rod 33, a second connecting rod 34 and a third connecting rod 35. The first connecting rod 31 is provided on the right side of the film barrel 2, and the two end surfaces of the first connecting rod 31 are fixedly connected to a slider 36. The protrusions on both sides of the workbench 1 are provided with an inverted L-shaped sliding groove 37, and the sliding groove 37 cooperates with the slider 36. A first rectangular block 32 is provided on the right side of the first connecting rod 31, and the bottom surface of the first rectangular block 32 is fixedly connected to the upper surface of the workbench 1. The first rectangular block 32 is provided with an L-shaped groove 38, and the inner walls on both sides of the L-shaped groove 38 are rotatably connected to the rotating rod 33, and the rotating rod 33 penetrates the first rectangular block 32 and extends to the outside of the first rectangular block 32. The end of the rotating rod 33 is fixedly connected to the turntable 5, and the surface of the rotating rod 33 is provided with a thread shape. The thread on the surface of the rotating rod 33 takes the middle of the rotating rod 33 as the dividing line, and the threads on both sides are rotated in opposite directions. The second connecting rod 34 and the third connecting rod 35 are threadedly connected to the rotating rod 33.

[0030] When the first connecting rod 31 is moved to the right, the first connecting rod 31 is moved to the right, and the required film material is pulled out to cover the upper surface of the cabinet door. When the slider 36 moves to the rightmost end of the slide groove 37, the slider 36 moves downward in the inverted L-shaped slide groove 37, so that the first connecting rod 31 is stuck in the slide groove 37, thereby fixing the required length of the film material and leveling the film material in the length direction. After the slider 36 moves to the rightmost end of the slide groove 37, the turntable 5 is rotated counterclockwise, and the turntable 5 drives the rotating rod 33 to rotate counterclockwise, and the rotating rod 33 drives the second connecting rod 34 and the third connecting rod 35 to rotate counterclockwise. The second and third links 34 and 35 are in a state of being moved in opposite directions, and the second and third links 34 and 35 are in a state of being moved in opposite directions.

[0031] As an embodiment of the present invention, the thickness of the second connecting rod 34 and the third connecting rod 35 is greater than that of the first connecting rod 31 , and a semicircular through groove 6 is provided on the right side of the second connecting rod 34 and the third connecting rod 35 , and the radius of the semicircular through groove 6 is greater than the width of the first connecting rod 31 .

[0032] By adopting the above technical solution, by setting the thickness of the second connecting rod 34 and the third connecting rod 35 to be greater than the thickness of the first connecting rod 31, a semicircular through groove 6 is provided on the right side of the second connecting rod 34 and the third connecting rod 35, and the radius of the semicircular through groove 6 is greater than the width of the first connecting rod 31. When the first connecting rod 31 moves to the rightmost end of the slide groove 37, the turntable 5 is rotated, and the turntable 5 drives the second connecting rod 34 and the third connecting rod 35 to rotate counterclockwise, thereby avoiding the interference of the first connecting rod 31 during the counterclockwise rotation of the second connecting rod 34 and the third connecting rod 35 and failing to fix the width of the film material and level it in the width direction.

[0033] As an embodiment of the present invention, a second rectangular block 7 is fixedly connected to the right side of the lower surface of the second connecting rod 34, a first blade 8 is fixedly connected to the right side of the lower surface of the second rectangular block 7, a third rectangular block 9 is fixedly connected to the left side of the lower surface of the third connecting rod 35, a second blade 10 is fixedly connected to the left side of the lower surface of the third rectangular block 9, the first blade 8 and the second blade 10 are semi-conical in shape, the sum of the heights of the second rectangular block 7 and the first blade 8 is the height of the first rectangular block 32, and the sum of the heights of the third rectangular block 9 and the second blade 10 is the height of the first rectangular block 32.

[0034] By adopting the above technical scheme, when the second connecting rod 34 and the third connecting rod 35 move to both sides driven by the rotating rod 33, the blade is driven to move to both sides. The blade cuts the required film material in the process of moving to both sides, without manual cutting, thereby improving work efficiency. By setting the sum of the heights of the second rectangular block 7 and the first blade 8 to be the height of the first rectangular block 32, and the sum of the heights of the third rectangular block 9 and the second blade 10 to be the height of the first rectangular block 32, when the second connecting rod 34 and the third connecting rod 35 are rotated to the point where their lower surfaces contact the film material, the second rectangular block 7 and the third rectangular block 9 can assist in pressing when the blade cuts the film material, so that the film material is initially fitted to the side of the cabinet door, which is convenient for cutting.

[0035] As an embodiment of the present invention, the film barrel 2 is rotatably connected to a support frame 11 , and the bottom surface of the support frame 11 is fixedly connected to the workbench 1 .

[0036] By adopting the above technical solution, by arranging the film material barrel 2 to be rotatably connected to the support frame 11, there is no need to manually hold the film material roll, which reduces the work intensity and can be taken out immediately after use, reducing the generation of waste, thereby saving film materials and reducing white pollution.

[0037] As an embodiment of the present invention, a brush 12 is fixedly connected to the lower surface of the first connecting rod 31 .

[0038] By adopting the above technical solution, by arranging the brush 12 on the first connecting rod 31, when the operator pulls the slider 36 to the right, the slider 36 drives the first connecting rod 31 to move to the right. The first connecting rod 31 moves to the right to pull the film material out of the film material barrel 2 and cover the cabinet door panel. At the same time, it can also drive the brush 12 to the right, so as to clean the dust on the upper surface of the cabinet door panel. This not only avoids the phenomenon that the film material cannot be effectively bonded to the cabinet door panel after heating due to the dust on the cabinet door panel surface, but also avoids the cabinet door panel behind the peritoneum becoming uneven due to dust, thereby affecting the appearance.

[0039] As an embodiment of the present invention, the second connecting rod 34 is longer than the first connecting rod 31 , and the length margin is the sum of the widths of the third connecting rod 35 and the fourth connecting rod.

[0040] By adopting the above technical solution, by setting the length of the second connecting rod 34 to be longer than the length of the first connecting rod 31, the length margin is the sum of the widths of the third connecting rod 35 and the fourth connecting rod. When the film material covers the surface of the cabinet door, the rotating rod 33 drives the second connecting rod 34 and the third connecting rod 35 to move to both sides, pressing the width margin of the film material down to the side of the cabinet door, and the first connecting rod 31 is not interfered with during the pressing process.

[0041] As an embodiment of the present invention, the brush 12 is made of high temperature resistant nylon.

[0042] By adopting the above technical solution, when the heating box 4 is working in coating operation, the heating temperature is between 100°C and 180°C, and the working environment is dry. The brush 12 is made of high temperature resistant nylon and will not deform at a high temperature of 300°C.

[0043] Working principle: After placing the cabinet door in the placement area on the workbench 1, a portion of the film material is pulled out from the film material barrel 2 and rolled up on the first connecting rod 31. After rolling up, the operator pulls the slider 36 to the right, and the slider 36 drives the first connecting rod 31 to move to the right. While the first connecting rod 31 moves to the right, the required film material is pulled out and the film material is covered on the upper surface of the cabinet door. When the slider 36 moves to the rightmost end of the slide groove 37, the slider 36 moves down in the inverted L-shaped slide groove 37, so that the first connecting rod 31 is stuck in the slide groove 37, thereby fixing the required length of the film material and being able to adjust the length direction. The film material is leveled, and after the slider 36 moves to the rightmost end of the slide slot 37, the turntable 5 is rotated counterclockwise, and the turntable 5 drives the rotating rod 33 to rotate counterclockwise, and the rotating rod 33 drives the second connecting rod 34 and the third connecting rod 35 to rotate counterclockwise. During the rotation process of the second connecting rod 34 and the third connecting rod 35, the left end surface contacts the film material. At this time, the second connecting rod 34 and the third connecting rod 35 continue to rotate counterclockwise, so the second connecting rod 34 and the third connecting rod 35 press the left film material down to fit it with the workbench 1. At this time, the left end surfaces of the second connecting rod 34 and the third connecting rod 35 are relatively fixed to the workbench 1, and the second connecting rod 34 The second and third connecting rods 34 and 35 can no longer rotate counterclockwise, so the turntable 5 continues to rotate counterclockwise. The rotating rod 33 continues to exert a force on the second and third connecting rods 34 and 35. At this time, since the threads on both sides of the rotating rod 33 rotate in opposite directions, the second and third rotating rods 33 move to both sides. While the second and third rotating rods 33 move to both sides, the blades cut the film material. When the second and third connecting rods 34 and 35 move to the end of the threads on the rotating rod 33, the rotating disk 5 stops rotating. The second and third connecting rods 34 and 35 move to both sides. During the process, the width of the film material can be fixed and the width direction can be leveled at the same time, and then the cabinet door covered with the film is transported to the heating box 4 for coating. After coating, exit the heating box 4, take out the cabinet door after cooling, rotate the turntable 5 clockwise, and when the second connecting rod 34 and the third connecting rod 35 move to the middle of the rotating rod 33, stop rotating the turntable 5, lift the slider 36, pull the slider 36 back to the left, and repeat the above actions to coat the next group of cabinet doors. The above actions can be completed by one staff member instead of 2-3 people, saving manpower and improving work efficiency.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
