[0001] This utility model belongs to the field of film embossing technology, and more specifically, it relates to an embossing device for PVC decorative film. Background Technology

[0002] Embossing equipment for PVC decorative film is widely used in decorative film processing. PVC decorative film is generally made through a heat-extending process, and then embossed with patterns using an embossing roller. Existing equipment has some problems, such as complex installation and disassembly of the embossing roller, time-consuming and labor-intensive replacement, which affects production efficiency and equipment convenience, and the inability to operate continuously when changing materials.

[0003] Patent CN222022202U discloses a film embossing machine, including a frame. Inside both sides of the frame, from left to right, are arranged a feeding roller and a take-up roller. At the rear of the frame is an unwinding mechanism that drives the feeding roller and take-up roller to rotate in the same direction.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, through the cooperation of the film roller, the lifting plate, and the take-up roller, enables film roller replacement without stopping the machine. It has two film rollers installed. When one film roller is empty, the film placed on the lifting plate can be quickly switched by extending and retracting the take-up roller, allowing for film winding operations on the other film roller. While one film roller is working, the used film roller can be removed and replaced by opening a door panel on one side of the other film roller, which is very convenient and quick, improving work efficiency.

[0017] 2. In this invention, when the take-up roller moves to one side of the film roller, the embossing rollers on both sides of the connecting rod support column on one side of the take-up roller move up and down to provide space for the take-up roller to approach the lifting plate 20. Multiple spaced-apart strip plates are installed on the take-up roller. When the magnetic strip on the lifting plate is hooked by the strip plate, the magnetic strip enters the inner shaft, completing the first step of moving the film from the film roller to the take-up roller, thus completing the fixing. When the take-up roller moves away from the film roller, under the action of the connecting rod, the embossing rollers on both sides squeeze towards the middle, embossing the film. This method does not affect the take-up roller's film collection or the embossing rollers' embossing function, making it very convenient. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figures 1 to 10 As shown, an embossing device for PVC decorative film includes a bracket 1. A plate 111 is vertically fixedly connected to the bracket 1. Two elliptical holes 110 are formed on the plate 111. A groove 112 is formed on one side of each elliptical hole 110. From top to bottom, elongated holes 113, 114, and 115 are formed on one side of the groove 112. The length directions of elongated holes 113 and 115 are aligned and perpendicular to elongated hole 114. A fixing plate 106 is fixedly connected to the middle of the end of the bracket 1 opposite to the plate. The fixing plate 106 has elongated holes 109, 108, and 105 from top to bottom. Two fixing posts 104 and one post 107 are fixedly connected to the outer side of the fixing plate 106. A bolt 12 is rotatably connected to post 107. A middle block 102 is fixedly connected to the bracket 1 on the side closest to the fixing plate 106. A rotating shaft 101 and a rotating shaft 103 are slidably connected to the upper and lower ends of the middle block 102, respectively. The rotating shafts 101 and 103 are slidably connected to the top and bottom of the bracket 1, respectively. The advantage of this design is that when one membrane roller 10 is working and the other is being prepared for replacement, only the fixing rod 11 on the door plate 8 of the membrane roller 10 to be replaced needs to be removed, and the door plate 8 can be slid outwards and then rotated. This will not affect the normal operation of the other membrane roller 10.

[0032] A membrane shaft 14 is slidably connected to two elliptical holes 110. One end of the membrane shaft 14 is rotatably connected to a membrane roller 10, and the other end passes through a side plate of the support 1 and is fixedly connected to a membrane shaft block 1401. A membrane shaft hole 1402 is provided on the membrane shaft block 1401. A lifting plate 21 is slidably connected to a slide groove 112. The lifting plate 21 includes a slider 2102 that is slidably connected to the slide groove 112. A slider hole 2103 is provided in the middle of the slider 2102. A lead screw 401 is threadedly connected to the slider hole 2103. One end of the lead screw 401 is fixedly connected to the support 1, and the other end is fixedly connected to a third servo 4. The third servo 4 is fixed to the top of the plate 111. An embossing roller 15 is slidably connected to two elongated holes 113 and 115. The embossing roller 15 is responsible for embossing the membrane. One end of the embossing roller 15 passes through the plate 111 and is rotatably connected to the connecting rod 16. A shaft 19 is slidably connected within the elongated hole 114. One end of the shaft 19 passes through the plate 111 and is rotatably connected to the two connecting rods 16. A gear 18 is fixedly connected to the shaft 19 on one side of the connecting rod 16. A movable block 17 is rotatably connected to the gear 18 on one side of the gear 18.

A take-up roller 20 is slidably connected to the outside of the splined shaft 1902. The splined shaft 1902 cooperates with the splined groove 2004, allowing the shaft 19 to drive the take-up roller 20 to rotate for take-up operations.

[0033] The film take-up roller 20 includes an inner shaft 2003. Inside the inner shaft 2003 is a spline groove 2004 that slidably connects to the spline shaft 1902. Baffles 2001 are fixedly connected to both ends of the inner shaft 2003. A ring of strip plates 2002, fixedly connected to the baffles 2001, is provided on the outer side of the inner shaft 2003. Both the strip plates 2002 and the inner shaft 2003 are made of magnetic metal. This allows both the strip plates 2002 and the inner shaft 2003 to attract the magnetic strip 1001, and the magnetic strip 1001 can be attracted to both sides of the strip plates 2002, facilitating feeding of the upper and lower film rollers 10. A second lead screw 301 is threaded into the film shaft hole 1402. One end of the second lead screw 301 is rotatably connected to the bracket 1, and the other end of the second lead screw 301 is fixedly connected to a second servo 3, which is fixedly connected to the plate 111. The function of the second servo 3 is to drive the second lead screw 301 to rotate, thereby moving the membrane shaft 14 up and down to keep the working membrane roller 10 and the two embossing rollers 15 horizontal and prevent membrane deformation. Magnetic strips 1001 are adsorbed and connected to both sides of the membrane at the opening of the membrane roller 10. The magnetic strips 1001 abut against the plate surface 2101 and can be adsorbed on the upper and lower sides of the plate surface 2101. Door plate 2 8 is rotatably connected to the first rotating shaft 101 and the second rotating shaft 103. The door plate 2 8 has two elliptical holes 802. The two elliptical holes 802 are aligned with the two elliptical holes 110, and the membrane shaft 14 is slidably connected in the elliptical holes 802. Door post 801 is fixedly connected to the outside of the door plate 2 8. A fixing rod 11 is slidably connected inside the door post 801. One end of the fixing rod 11 is fixedly connected to the fixing post 104. A slide rail 6 is fixedly connected to one side bracket 1 of the elongated opening hole 108. A slide block 7 is slidably connected to the slide rail 6. A door panel 5 is fixedly connected to the slide block 7. An elongated opening hole 501 is opened on the door panel 5. The elongated opening hole 501 is aligned with the elongated opening hole 108. The elongated opening hole 501 is rotatably connected to the spline shaft 1902. A post 502 is fixedly connected to the outside of the door panel 5. A door bolt 12 is movably connected to the post 502.

[0034] On the side of plate 111 facing away from fixed plate 106, gear 116 is rotatably connected to both ends of elongated hole 4 114. A chain wheel 117 is fixedly connected to one side of gear 116. The two gears 116 mesh with gear 2 18 respectively. A drive mechanism 13 is fixedly connected to the bottom support 1 between the two gears 116. Two chain wheels 117 are fixedly connected to the extended end of the drive mechanism 13. Chains 1301 mesh with the two chain wheels 117 on the drive mechanism 13. The two chains 1301 mesh with the chain wheels 117 on the two gears 116 respectively. A horizontal plate 118 is fixedly connected to one side of plate 111 of one gear 116. A lead screw 201 is rotatably connected to the horizontal plate 118. The lead screw 201 is threaded into threaded hole 1701. A first servo 2 is fixedly connected to one end of the lead screw 201. The first servo 2 is fixedly connected to the support 1.

[0035] In this utility model, door panel 5 and door panel 8 do not bear weight; they can bear weight by simply being close to one side panel 111. The function of door panel 5 and door panel 8 is to hold the film roller 10 and the take-up roller 20 in case of emergency.

[0036] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.

[0037] Working process: First, pull the fixing rod 11 out from the second door panel 8, pull the second door panel 8 backward to separate the membrane shaft 14 from the elliptical hole 802, then rotate the second door panel 8, install the membrane rollers 10 on the two membrane shafts 14, and attract the magnetic strip 1001 to the open end of the membrane roller 10. Then place one of the membranes with the magnetic strip 1001 on or under the plate surface 2101 for attraction. Then push the second door panel 8 forward to re-enter the membrane shaft 14 into the elliptical hole 802. Finally, fix the fixing rod 11 from the second door panel 8.

[0038] The second step is to start the first servo 2, which drives the lead screw 201 to rotate. When the lead screw 201 rotates, it drives the moving block 17 to move closer to the film roller 10. Then the shaft 19 moves together towards the film roller 10. When the film roller 10 moves, the connecting rod 16, which is rotatably connected to the shaft 19, will drive the embossing rollers 15 on both sides to move up and down along the elongated hole 113, making room for the movement of the shaft 19. When gear 18 meshes with gear 116 next to film roller 10, screw 201 stops rotating. At this time, the take-up roller 20 on the outside of shaft 19 approaches the plate surface 2101, and magnetic strip 1001 passes through the gap of strip plate 2002 and attracts the inner shaft 2003. The drive mechanism 13 is started to drive the chain 1301 to rotate, and then drive gear 116 to rotate. Gear 116 drives gear 18 to rotate, and slowly drives take-up roller 20 to rotate. The film is first wrapped around take-up roller 20 a few times to fix it. Finally, the first servo 2 drives screw 201 to move in the opposite direction and pushes shaft 19 to the other side. When shaft 19 moves, connecting rod 16 connected to shaft 19 will drive the embossing rollers 15 on both sides to move from both sides to the middle, and finally squeeze the film.

[0039] In the third step, when shaft 19 moves to the initial position, gear 18 engages with gear 116 on the side away from film roller 10, and drive mechanism 13 drives film take-up roller 20 to take up film, while embossing roller 15 performs embossing operation on film.

[0040] Fourth step: After the take-up roller 20 finishes taking up the film, rotate the latch 12 to disengage it from the second column 502, push the first door plate 5 to one side to cut the film, and then remove the take-up roller 20 from the spline shaft 1902. Replace it with a new take-up roller 20 to continue the operation.

[0041] Because two film rollers 10 are installed, when one is in operation, there is no need to stop the operation when the film on the other film roller 10 runs out. Simply open the door panel 2 8 on the side without film to replace it. The film on the upper film roller 10 will be attracted to the plate surface 2101 at the opening by the magnetic strip 1001, and the film on the lower film roller 10 will be attracted to the lower part of the plate surface 2101 by the magnetic strip 1001 at the opening. In order to prevent the plate surface 2101 from affecting the operation, after the film on the plate surface 2101 is removed, the third servo 4 rotates the lead screw 3 401 to drive the plate surface 2101 to rise or fall.

[0042] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
