Description

Technical Field

[0001] This utility model relates to the field of PVB interlayer film cutting technology, specifically a cutting precision calibration device for the production of PVB interlayer film for art glass. Background Technology

[0002] Currently, PVB interlayer is a semi-transparent film. PVB interlayer is mainly used in laminated glass, which is a special glass made by sandwiching a layer of PVB film between two pieces of glass and then bonding them under high pressure and heating. PVB laminated glass is widely used in industries such as construction, automobiles, and photovoltaics because it has multiple functions such as safety, heat insulation, noise control, and ultraviolet protection.

[0003] Patent CN210061314U discloses a rapid positioning PVB interlayer film cutting device, including a base. A bracket is welded to the top right side of the base. An electric push rod A is fixedly installed on the top left side of the bracket. A blade is fixedly installed at the bottom of the electric push rod A. An electric push rod B is embedded inside the left side of the base. A sliding groove is opened on the left side of the electric push rod B. A slider is movably placed in the sliding groove. The right side of the slider is fixedly welded to the left end of the electric push rod B. A limit plate is welded to the top of the slider and located on the surface of the base. An electric push rod C is installed on the rear side of the top of the base. The electric push rod B can be started by a PLC controller. The extension and retraction of the electric push rod B can drive the slider to move left and right in the sliding groove, thereby driving the limit plate to move left and right on the base. At this time, the distance between the limit plate and the blade will change, so that the positioning can be quickly positioned during cutting, realizing the cutting of PVB interlayer film of different sizes. The adjustment method is simple and convenient, saving time and effort.

[0004] When using the above-mentioned cutting equipment, due to the different hardness of different types of PVB interlayer films, the PVB interlayer film is easily deformed during cutting, and burrs and dimensional deviations are likely to occur, resulting in the cutting accuracy not meeting the requirements. Utility Model Content

[0005] The purpose of this invention is to provide a cutting precision calibration device for the production of PVB interlayer film for art glass, so as to solve the problem mentioned in the background art that the hardness of PVB interlayer film will cause cutting deformation, resulting in the cutting precision not meeting the requirements.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting precision calibration device for the production of PVB interlayer film for art glass, comprising a worktable, a shelf on the surface of the worktable, a connecting rod fixed to one side of the shelf, a cylinder fixed to the bottom of the worktable, and the output end of the cylinder fixedly connected to one end of the connecting rod, two guide rails symmetrically fixed to the surface of the worktable, each guide rail having a limit block fixed on it, sliders symmetrically fixed to both sides of the shelf, the sliders matching the guide rails, positioning blocks fixed to the four corners of the shelf, and a heating chamber disposed in the middle of the shelf.

[0007] Furthermore, heating tubes are uniformly fixed to the inner wall of the heating chamber, and a metal heat-conducting plate is provided on the top of the heating chamber, and the metal heat-conducting plate is fixedly connected to the placement plate.

[0008] Furthermore, a fixed frame is fixed on the workbench, a drive motor is fixed at the middle position of the fixed frame, and a first bevel gear is installed at the output end of the drive motor.

[0009] Furthermore, a second bevel gear is meshed with the first bevel gear, and a rotating shaft is coaxially fixed to the second bevel gear.

[0010] Furthermore, cams are fixed at both ends of the rotating shaft, and brackets are symmetrically installed on the rotating shaft, with the bottom end of the brackets fixedly connected to the fixing frame.

[0011] Furthermore, two lifting rods are symmetrically inserted through the fixing frame, and a cutting blade is fixed to the bottom end of the two lifting rods, and a lifting plate is fixed to the top end of the two lifting rods.

[0012] Furthermore, springs are nested on the outer sides of both lifting rods, with one end of the spring fixedly connected to the fixing frame and the other end fixedly connected to the lifting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This cutting precision calibration device for the production of PVB interlayer film in art glass uses positioning blocks at the four corners of the placement plate to facilitate accurate placement of the PVB interlayer film on the placement plate. A heating chamber is set inside the center of the placement plate. Before cutting, the heating tube in the heating chamber generates heat, which is transferred to the PVB interlayer film through a metal heat-conducting plate. The center of the PVB interlayer film softens due to the heat, preventing deformation of the PVB interlayer film during cutting and improving cutting precision.

[0015] Furthermore, the cylinder pulls the shelf through the connecting rod, causing the shelf to slide on the worktable. Sliders are symmetrically fixed on both sides of the shelf, and the sliders slide on the guide rail, causing the shelf to move along a fixed trajectory. Limit blocks are fixed on the guide rail. After the slider contacts the limit block, the shelf is exactly below the cutting blade, which allows for precise adjustment of the cutting position.

[0016] Furthermore, the drive motor rotates the first bevel gear, and the cams fixed at both ends of the shaft rotate synchronously with the shaft. When the cams rotate, they push the lifting plate downwards, causing the spring to deform. The lifting rod lowers the cutting blade fixed at the bottom. After the cam rotates half a turn, the cutting blade descends to the lowest point and cuts the PVB interlayer film on the plate. When the cam rotates a full turn, the cutting blade returns to its original position. The two lifting plates and the lifting rod are vertically displaced by the squeezing action of the cams. The two lifting rods lower the cutting blade to cut the PVB interlayer film, making the PVB interlayer film more evenly stressed and the cut surface smoother. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-5 This utility model provides the following technical solution: a cutting precision calibration device for the production of PVB interlayer film for art glass, including a workbench 1, a shelf 2 on the surface of the workbench 1, a connecting rod 3 fixed on one side of the shelf 2, a cylinder 4 fixed at the bottom of the workbench 1, and the output end of the cylinder 4 fixedly connected to one end of the connecting rod 3, two guide rails 5 symmetrically fixed on the surface of the workbench 1, each guide rail 5 having a limit block 6 fixed on it, sliders 22 symmetrically fixed on both sides of the shelf 2, and the sliders 22 matching the guide rails 5, positioning blocks 7 fixed at the four corners of the surface of the shelf 2, a heating chamber 8 inside the middle position of the shelf 2, heating tubes 9 uniformly fixed on the inner wall of the heating chamber 8, a metal heat-conducting plate 10 on the top of the heating chamber 8, and the metal heat-conducting plate 10 fixedly connected to the shelf 2.

[0026] When cutting the rigid PVB interlayer, the PVB interlayer is placed on the placement plate 2. Positioning blocks 7 are fixed at each of the four corners of the placement plate 2 to help position the PVB interlayer and prevent positional deviations that could reduce cutting accuracy. Then, the cylinder 4 is activated, acting on the connecting rod 3, which pulls the placement plate 2 to slide on the worktable 1. Slider blocks 22 are symmetrically fixed on both sides of the placement plate 2, and these sliders 22 match the guide rail 5, allowing the placement plate 2 to move along a fixed trajectory. Limit blocks 6 are fixed on the guide rail 5. When the slider 22 contacts the limit block 6, the cylinder 4 stops. When the work is stopped, the placement plate 2 is located directly below the cutting blade 19, thus completing the adjustment of the cutting position. A heating chamber 8 is set inside the middle position of the placement plate 2. The heating tube 9 in the heating chamber 8 generates heat, which is transferred to the PVB interlayer film through the metal heat-conducting plate 10. The middle position of the PVB interlayer film softens due to heat, which prevents the PVB interlayer film from deforming during cutting and can improve the cutting accuracy. When the cutting blade 19 cuts the PVB interlayer film, the cutting blade 19 descends to the lowest point and contacts the metal heat-conducting plate 10, avoiding direct contact between the cutting blade 19 and the placement plate 2 and reducing the chance of damage to the placement plate 2.

[0027] Example 2: Please refer to Figure 6Based on Embodiment 1, a cutting structure is also disclosed, the specific structure of which is as follows: A fixed frame 11 is fixed on the workbench 1, a drive motor 12 is fixed in the middle of the fixed frame 11, and a first bevel gear 13 is installed at the output end of the drive motor 12; a second bevel gear 14 is meshed on the first bevel gear 13, and a rotating shaft 15 is coaxially fixed on the second bevel gear 14; cams 16 are fixed at both ends of the rotating shaft 15, and brackets 17 are symmetrically installed on the rotating shaft 15, and the bottom end of the brackets 17 is fixedly connected to the fixed frame 11; two lifting rods 18 are symmetrically passed through the fixed frame 11, and a cutting blade 19 is fixed at the bottom end of the two lifting rods 18, and a lifting plate 21 is fixed at the top end of the two lifting rods 18; a spring 20 is nested on the outside of the two lifting rods 18, one end of the spring 20 is fixedly connected to the fixed frame 11, and the other end is fixedly connected to the lifting plate 21.

[0028] When the drive motor 12 is turned on, it drives the first bevel gear 13 to rotate. The first bevel gear 13 drives the second bevel gear 14, which meshes with it, to rotate. A rotating shaft 15 is coaxially fixed on the second bevel gear 14. Cams 16 fixed at both ends of the rotating shaft 15 rotate synchronously with the rotating shaft 15. Two brackets 17 are symmetrically installed on the rotating shaft 15. The brackets 17 support the rotating shaft 15 without affecting its rotation. When the cams 16 rotate, they push the lifting plate 21 downward. The lifting plate 21 is supported by a spring 20. When the lifting plate 21 descends, the spring 20 deforms. The lifting plate 21 is fixed with a lifting rod 18 at the middle position. The lifting rod 18 lowers the cutting blade 19 fixed at the bottom. After the cam 16 rotates half a turn, the cutting blade 19 descends to the lowest point and cuts the PVB intermediate film on the shelf 2. Then the cam 16 continues to rotate, and the lifting plate 21 rises with the lifting rod 18 and the cutting blade 19 under the reset action of the spring 20. When the cam 16 rotates a full turn, the cutting blade 19 resets. At this time, the cylinder 4 drives the connecting rod 3, and the connecting rod 3 pushes the shelf 2 back to its original position to complete the next cutting operation.
