Description

Technical Field

[0001] This invention relates to the field of glass coating technology, and more specifically to a trimming mechanism for a glass coating machine. Background Technology

[0002] After the glass is manufactured, a protective film needs to be applied to the glass surface for subsequent transportation and other operations to prevent damage to the glass surface. First, a glass laminating machine is used to apply the film to the glass. Since the glass production size is different, and the size and width of different models of glass are different, the width of the protective film is wider than the width of the glass. In order to ensure the neatness of the lamination, after the protective film is applied to the glass, the protective film at the edge of the glass needs to be cut off.

[0003] The patent announcement number CN218557341U discloses a glass panel coating and cutting machine, which includes a cutting frame, a mounting bracket, a rotary two-end cutting mechanism, a movable two-side cutting mechanism, and a bidirectional detachable conveying mechanism. The mounting bracket is welded to the top of the cutting frame, the bidirectional detachable conveying mechanism is fixedly installed inside the cutting frame, and the rotary two-end cutting mechanism and the movable two-side cutting mechanism are both fixedly installed at the bottom of the mounting bracket. The rotary two-end cutting mechanism includes a first motor, a mounting base, an adjusting hydraulic column, an extrusion plate, and a pressing cutting blade. The first motor is fixed to the bottom of the mounting bracket, and the mounting base is connected to the output shaft of the first motor, which can effectively cut the edges of the glass.

[0004] However, after a period of use, the sharpness of the cutting scissors will decrease. If the cutting scissors are not sharpened in time, they will become dull. This will cause the film to be stretched and displaced to a certain extent when it comes into contact with the cutting blade, resulting in wrinkles at the cut part of the packaging film. Summary of the Invention

[0005] The purpose of this invention is to provide a trimming mechanism for a glass coating machine to solve the technical problem that the dulling of the cutter blade affects the cutting effect in the prior art.

[0006] The technical problem to be solved by this invention can be achieved through the following technical solution:

[0007] A trimming mechanism for a glass coating machine includes a support frame, a conveying assembly for conveying glass is fitted on the top of the support frame, and a coating device is also provided on the upper surface of the support frame. The mechanism further includes:

[0008] The system comprises two feed blocks, with an inverted U-shaped mounting bracket at the top of the support frame. A hollow column is rotatably connected between the two side walls of the mounting bracket, and an external motor for driving the hollow column to rotate is mounted on the mounting bracket. An adjustment component is installed inside the hollow column to move the two feed blocks closer or further apart. A blade holder is connected to each feed block, and a cutter for cutting the film is fixed to the outside of the blade holder. A guide rod is rotatably connected between the two side walls of the mounting frame, and a linkage component for driving the guide rod to rotate is configured between the guide rod and the hollow column. A movable frame is fixed to the top of each feed block. The movable frame is an inverted U-shaped plate, and grinding blocks are elastically mounted on both side walls of the movable frame. Two grinding blocks cooperate with the two sides of the cutter. A drive component is configured between the side wall of the movable frame and the corresponding grinding block to drive the two grinding blocks to move closer and grind the corresponding cutter. A cleaning component for cleaning the cutter is also provided on the movable frame.

[0009] As a further embodiment of the present invention: the adjustment component includes an internal motor, a screw is rotatably connected inside the hollow column, the internal motor is fixedly connected inside the hollow column and is used to drive the screw to rotate, symmetrical threaded grooves are provided on the outer sides of both ends of the screw, and feed blocks are threadedly connected to both ends of the screw, through slots are opened on the upper and lower sides of the hollow column, and the feed blocks pass through the through slots to connect with the corresponding external motors.

[0010] As a further aspect of the present invention: the linkage component includes a driving gear, which is fixedly connected to the outside of the hollow column, and a driven gear is fixedly connected to the outside of the guide rod, wherein the driving gear and the driven gear are meshed together.

[0011] As a further aspect of the present invention: the two side walls of the movable frame are provided with through holes, the guide rod passes through the through holes and does not contact the through holes, the guide rod is cross-shaped, the inner ring of the grinding block is provided with a magnetic ring, the inner side of the magnetic ring is provided with a cross groove adapted to the guide rod, and the magnetic ring is slidably connected to the guide rod.

[0012] As a further aspect of the present invention: a rotating ring is rotatably connected to each of the through holes, and several telescopic rods are distributed between the rotating ring and the grinding block. A spring is also provided between the rotating ring and the grinding block, with one end of the spring connected to the grinding block and the other end connected to the rotating ring.

[0013] As a further aspect of the present invention: the driving component includes an electromagnet, the electromagnet cooperating with a magnetic ring, and electromagnets are provided on both inner sidewalls of the movable frame. A connecting wire is connected to the electromagnet, and the other end of the connecting wire is connected to an external power source.

[0014] As a further aspect of the present invention, a thermoplastic bimetallic strip is also provided between the electromagnet and the external power supply.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1-7As shown, a trimming mechanism for a glass coating machine includes a support frame 1. A conveying assembly 2 for transporting glass is fitted on the top of the support frame 1. A coating device 3 for coating the glass is also provided on the upper surface of the support frame 1. The mechanism also includes two feed blocks 52. An inverted U-shaped mounting bracket 4 is fixedly mounted on the top of the support frame 1. A hollow column 41 is rotatably connected between the two side walls of the mounting bracket 4. A limiting protrusion 53 is provided on the inner wall of the hollow column 41. The feed blocks 52 are slidably connected to the limiting protrusion 53 to ensure the stability of the sliding of the feed blocks 52. The mounting bracket 4 is also equipped with... An external motor 42 is provided to drive the hollow column 41 to rotate. An adjustment assembly is installed inside the hollow column 41 to move the two feed blocks 52 closer together or further apart. A cutter holder 43 is fixedly connected to each feed block 52. The cutter holder 43 is annular, slidably connected to the outside of the hollow column 41, and fixedly connected to the feed block 52. An annular cutter 44 for cutting the membrane is fixed to the outside of the cutter holder 43. A guide rod 6 is rotatably connected between the two side walls of the mounting frame 4. A linkage assembly for driving the guide rod 6 to rotate is provided between the guide rod 6 and the hollow column 41. Each feed block 52 has a fixed connection to the feed block 52. Each of the feed blocks 52 has a fixed movable frame 63 on its top. The movable frame 63 is an inverted U-shaped plate. Grinding blocks 65 are elastically mounted on both sides of the movable frame 63. The two grinding blocks 65 cooperate with the two sides of the cutter 44. The two grinding blocks 65 are located on both sides of the cutter 44 but do not contact the cutter 44. A drive assembly is fitted between the side wall of the movable frame 63 and the corresponding grinding block 65. In actual use, the glass is first coated using the coating device 3. The coated glass panel is then conveyed and moved by the conveying assembly 2. During the conveying process, an external motor is used. 42 drives the hollow column 41 to rotate, and the rotation of the hollow column 41 drives the cutter 44 to rotate to cut the excess film on both sides of the glass panel. The drive component is used to drive the two grinding blocks 65 to approach and fit against the corresponding sides of the cutter 44. During the rotation of the hollow column 41, it can drive the guide rod 6 to rotate, and the rotation of the guide rod 6 drives the grinding blocks 65 to rotate to grind the cutter 44, which can ensure the sharpness of the cutter 44. The moving frame 63 is also equipped with a cleaning component for cleaning the cutter 44. Activating the drive component drives the grinding blocks 65 on both sides to clamp the cutter 44.

[0030] In some specific implementation plans, such as Figure 3As shown, to facilitate trimming of films of different widths, the adjustment assembly includes an internal motor 5. A screw 51 is rotatably connected inside the hollow column 41. The internal motor 5 is fixedly connected inside the hollow column 41 and is used to drive the screw 51 to rotate. Symmetrical threaded grooves are provided on the outer sides of both ends of the screw 51. Feed blocks 52 are threadedly connected to both ends of the screw 51. Through slots 45 are opened on the upper and lower sides of the hollow column 41. The feed blocks 52 pass through the through slots 45 and are connected to the corresponding external motors 42. When the internal motor 5 is started, it drives the screw 51 to rotate. When the screw 51 rotates, it can drive the feed blocks 52 on both sides to move towards each other. The feed blocks 52 can drive the external motors 42 and the cutter 44 to move synchronously. The distance between the two cutters 44 can be adjusted, thereby cutting films of different widths.

[0031] In some specific implementation plans, such as Figure 2 As shown, in order to facilitate the rotation of the hollow column 41 to drive the driven gear 62 to rotate, the linkage assembly includes a driving gear 61, which is fixedly connected to the outside of the hollow column 41. The driven gear 62 is fixedly connected to the outside of the guide rod 6. The driving gear 61 and the driven gear 62 are meshed together. When the hollow column 41 rotates, it drives the driving gear 61 to rotate synchronously. The rotation of the driving gear 61 drives the driven gear 62 and the guide rod 6 to rotate in opposite directions.

[0032] In some specific implementation plans, such as Figure 2 or Figure 5 As shown, in order to ensure that the rotation of the guide rod 6 does not affect the moving frame 63, through holes are provided on both sides of the moving frame 63. The guide rod 6 passes through the through holes but does not contact them. The guide rod 6 is cross-shaped. A magnetic ring 66 is provided on the inner ring of the grinding block 65. A cross groove that matches the guide rod 6 is provided on the inner side of the magnetic ring 66. The magnetic ring 66 slides along the outer wall of the guide rod 6 and can rotate with the guide rod 6.

[0033] In some specific implementation plans, such as Figure 7 As shown, in order to facilitate the reset of the grinding block 65, a rotating ring 64 is rotatably connected inside the through hole. Several telescopic rods 7 are distributed between the rotating ring 64 and the grinding block 65 for limiting the position. A spring 71 is also provided between the rotating ring 64 and the grinding block 65 for reset. One end of the spring 71 is connected to the grinding block 65 and the other end is connected to the rotating ring 64. In the absence of external force, the spring 71 pulls the grinding block 65 closer to the inner wall of the moving frame 63, so that the grinding block 65 moves away from the cutter 44.

[0034] In some specific implementation plans, such as Figure 6As shown, in order to facilitate the grinding block 65 to approach the cutter 44, the drive assembly includes an electromagnet 72. The electromagnet 72 cooperates with the magnetic ring 66. Electromagnets 72 are provided on both inner side walls of the moving frame 63. A connecting wire 73 is connected to the electromagnet 72. The other end of the connecting wire 73 is connected to an external power supply. When the electromagnet 72 is energized, the electromagnet 72 generates a repulsive force on the magnetic ring 66 of the same level, so that the grinding block 65 fits against the cutter 44.

[0035] In some specific implementation plans, such as Figure 6 As shown, in order to facilitate automatic stopping and cutting off the circuit, a bimetallic strip 74 is also provided between the electromagnet 72 and the external power supply. Current is continuously transmitted to the bimetallic strip 74, causing the temperature of the bimetallic strip 74 to continuously increase. The working principle of the bimetallic strip 74 is to use the different thermal expansion coefficients of the two metals to produce bending deformation when the temperature changes, thereby controlling the on and off of the circuit.

[0036] In some specific implementation plans, such as Figure 5 or Figure 6 As shown, to facilitate cleaning of the cutter 44, the cleaning assembly includes a U-shaped frame 81. A mounting rod 8 is fixed to the side of the U-shaped frame 81. The U-shaped frame 81 is detachably connected to the movable frame 63 via the mounting rod 8. A cleaning block 82 is provided inside the U-shaped frame 81. The cleaning block 82 fits against the cutter 44. As the mounting frame 4 rotates, the cleaning block 82 contacts the surface of the cutter 44, cleaning the residual dust and impurities on the surface of the cutter 44. This ensures that the cutter 44 remains clean and maintains the sharpness of the blade during the cutting process.

[0037] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:

[0038] In actual use, the glass is first coated with a film using the coating device 3. The coated glass panel is then conveyed and moved by the conveying component 2. During the conveying process, the hollow column 41 is rotated by the external motor 42. The rotation of the hollow column 41 drives the cutter 44 to rotate and cut off the excess film on both sides of the glass panel. Before use, the internal motor 5 is started to drive the screw 51 to rotate. While the screw 51 rotates, it drives the feed blocks 52 on both sides to move towards each other. The feed blocks 52 can drive the external motor 42 and the cutter 44 to move synchronously. The distance between the two cutters 44 can be adjusted, so that films of different widths can be cut. It has strong applicability. During the movement of the feed blocks 52, the moving frame 63 moves with it, so that the grinding blocks 65 are always on both sides of the cutter 44. Then, the electromagnet 72 is energized. The electromagnet 72 generates a repulsive force on the magnetic ring 66, so that the grinding blocks 65 on both sides clamp the outer edge of the cutter 44.

[0039] During operation, the hollow column 41 rotates, driving the drive gear 61 to rotate. This causes the driven gear 62, meshing with the drive gear 61, to rotate the guide rod 6. The rotation of the guide rod 6 causes the grinding block 65 to rotate as well, allowing the grinding block 65 to grind the cutter 44, ensuring that the cutter 44 maintains sufficient sharpness during trimming. As current is continuously transmitted to the bimetallic strip 74, its temperature continuously increases. When the temperature reaches a specific thermal expansion "critical point" of the bimetallic strip 74, the current path is broken, and the electromagnet 72 no longer forms a magnetic field and affects the magnetic ring 6. 6. Due to the rebound force of spring 71, magnetic ring 66, carrying grinding block 65, moves towards the inner wall of moving frame 63, restoring it to a state where it is not in contact with cutter 44, thus stopping the grinding of cutter 44 and preventing prolonged grinding from affecting the service life of cutter 44. The cutter 44 is automatically ground every time the equipment is turned on, and the grinding stops automatically afterward, eliminating the need for manual inspection each time, making it convenient to use. While cutter 44 rotates, cleaning block 82 contacts the surface of cutter 44 to clean residual dust and impurities on the surface of cutter 44, thus keeping cutter 44 clean and sharp during the cutting process.

[0040] The foregoing has described several embodiments of the present invention in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of the invention. All equivalent variations and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
