Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for glass laminating machines, and specifically to a cutting device for a glass laminating machine. Background Technology

[0002] The final step in the cold-end processing of glass manufacturing is packaging. High-quality glass typically requires double-sided lamination to prevent surface damage during transportation and storage. A glass laminating machine is a type of intelligent manufacturing equipment used to cover the glass surface with a thin film for various purposes, such as protection, decoration, or functionality. After applying a layer of plastic film to both the top and bottom surfaces of the glass on the laminating machine, the films must be cut to allow for stacking. However, the common practice is to insert a blade directly into the gap between two panes of glass and then cut the connecting film laterally. Due to friction and vibration during glass transport, the glass position may deviate, resulting in blade impact with the glass at the cutting point and uneven cutting.

[0003] The cutting device for glass coating machines is a precision cutting tool used to cut the film during the coating process, ensuring that the protective film on the glass surface is covered smoothly and accurately. Existing technology uses non-standard blades, which are expensive and have inconsistent performance. Installation is also relatively cumbersome.

[0004] Utility model patent CN212218589U discloses a film-cutting device for a glass coating machine. To ensure a secure blade connection, a mounting block is installed on the top wall of the cutting blade. The position of the cutting blade is restricted by limiting the position of the mounting block. Therefore, a sealing method is often required to firmly connect the blade and the mounting block. When the blade needs to be replaced, the mounting block is also discarded, resulting in resource waste. Furthermore, the blade may still loosen over prolonged use. Therefore, the existing technology still needs improvement. Utility Model Content

[0005] In view of this, the present invention provides a cutting device for a glass coating machine, which can at least solve the technical problems of poor performance and easy damage of existing cutting devices.

[0006] This utility model discloses a cutting device for a glass coating machine, comprising a clamp configured to move horizontally under the control of a guiding mechanism. The clamp includes a blade, a mounting plate, a magnet, and a clamping plate. The blade is a double-sided stainless steel industrial blade. The mounting plate has a fixing groove for holding the blade, one end of which extends beyond the lower edge of the mounting plate. The width of the fixing groove is the same as the width of the blade, and the length of the fixing groove is less than the length of the blade. A positioning hole is provided on the blade. A positioning pin for insertion into the positioning hole is provided on the groove wall of the fixing groove. The magnet is disposed in the fixing groove for adsorbing the blade. The clamping plate extends downwards, and the mounting plate is detachably connected to the clamping plate via a connector. A pressure plate is provided on the clamping plate to press against the blade.

[0007] In some embodiments, the cutting device for the glass coating machine further includes a steel sheet with mounting holes for passing through the positioning post. The steel sheet is disposed between the blade and the pressure plate to cover the surface of the blade.

[0008] In some embodiments, the fixing groove is inclined relative to the horizontal plane.

[0009] In some embodiments, there are two clamps, which are rotatably connected by a horizontally arranged pin, with the clamping plate located below the axis of rotation. The clamps also include a guide plate located above the axis of rotation, and a connecting plate connecting the clamping plate and the guide plate, the connecting plate being rotatably connected to the pin; in the horizontal direction, the distance from the clamping plate to the pin axis is less than the distance from the guide plate to the pin axis. The cutting device for the glass coating machine also includes a drive mechanism for controlling the two clamping plates to approach or separate.

[0010] In some embodiments, the mounting plate is disposed on one side of the two clamps that are opposite to each other.

[0011] In some embodiments, the thickness of the two clamping plates gradually decreases from top to bottom. When the opposite sides of the two clamping plates are in a vertical state, the two guide plates are in a vertical state, and the distance between the sides of the two clamping plates that are close to each other gradually increases from top to bottom.

[0012] In some embodiments, the drive mechanism includes a cylinder disposed between two guide plates; the cylinder is configured to have a first state controlling the two guide plates to move away from each other and a second state controlling the two guide plates to move closer to each other.

[0013] In some embodiments, the cylinder is mounted on the frame; the drive mechanism also includes a tension spring, the two ends of which are respectively connected to the tops of two guide plates.

[0014] In some embodiments, the clamping plate is further provided with a first mounting hole; a second mounting hole is provided at a corresponding position on the mounting plate, and the connecting element is a bolt and nut assembly, with the bolt passing through the first mounting hole and the second mounting hole.

[0015] In some embodiments, the fixing groove is further provided with a slot for placing a magnet block.

[0016] The beneficial effects of this utility model are as follows: This application uses double-sided stainless steel industrial blades to cut the upper and lower films on glass. The product is inexpensive and readily available, the blades are sharp, and the cutting edges are neat. By setting a mounting plate for positioning the blade, with fixing grooves and positioning posts on the mounting plate, the blade movement can be prevented. Magnetic blade suction is used to prevent the blade from falling off during installation, which can improve the efficiency of blade replacement, make the blade installation firm, and make operation simple and convenient.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described in detail below with reference to specific examples and accompanying drawings.

[0028] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0029] This utility model provides a cutting device for a glass coating machine, which is positioned above the glass production line (e.g., ...). Figure 7 As shown, it includes a clamp that can move horizontally under the control of a guiding mechanism for cutting the coating on the glass. The guiding mechanism can be, for example, a telescopic cylinder. The clamp includes a blade 10, a mounting plate 1, a magnet block, and a clamping plate 2. The blade 10 is a double-sided stainless steel industrial blade, shaped as shown... Figure 5 As shown, it has standard size specifications and the advantages of sharp blades (10mm) and low price. Figure 4 and Figure 5 As shown, the mounting plate 1 has a fixing groove 7 for placing the blade 10. One end of the fixing groove 7 extends beyond the lower edge of the mounting plate 1. The width of the fixing groove 7 is the same as the width of the blade 10, and the length of the fixing groove 7 is less than the length of the blade 10, so that the blade 10 can be just inserted into the fixing groove 7. When the blade 10 is in the fixing groove 7, a portion of the lower end of the blade 10 protrudes from the fixing groove 7 to cut the coating. The blade 10 has a positioning hole. The groove wall of the fixing groove 7 has a positioning post 9 for inserting into the positioning hole to define the installation position of the blade 10. A magnet is disposed in the fixing groove 7 to attract the blade 10, preventing the blade 10 from falling off during installation and improving the convenience and safety of operation. The clamping plate 2 extends downward, and the mounting plate 1 is detachably connected to the clamping plate 2 via a connector. The clamping plate 2 is provided with a pressure plate 12 that presses against the blade 10. Specifically, the outer contour of the pressure plate 12 is basically the same as the outer contour of the fixing groove 7, but its size is slightly smaller than that of the fixing groove 7, which facilitates the tight pressing and fixing of the blade 10.

[0030] Compared with the prior art, this utility model uses a double-sided stainless steel industrial blade to cut the upper and lower films on glass. The product is inexpensive and readily available, the blade 10 is sharp, and the cutting edge is neat. By setting a mounting plate 1 for positioning the blade 10, and the mounting plate 1 is provided with a fixing groove 7 and a positioning post 9, the blade 10 can be prevented from moving. The blade 10 is magnetically attracted to prevent it from falling off during installation, which can improve the efficiency of blade replacement, make the blade 10 firmly installed, and make the operation simple and convenient.

[0031] In some embodiments, such as Figure 6 As shown, the cutting device for the glass coating machine also includes a steel sheet 11. The steel sheet 11 has mounting holes for passing through the positioning post 9. The steel sheet 11 is positioned between the blade 10 and the clamping plate 2 to cover the surface of the blade 10. By using the steel sheet 11, the pressure plate 12 does not directly contact the blade 10, thus buffering the force acting on the blade 10, protecting the blade 10, and increasing the stability of the blade 10 installation.

[0032] In some embodiments, the fixing groove 7 is inclined relative to the horizontal plane, so that the blade 10 is also inclined relative to the horizontal plane. The inclination angle is preferably set to 30 to 60°, so that the blade 10 can smoothly cut the film during the movement.

[0033] In some embodiments, such as Figure 1 As shown, there are two clamps, which are rotatably connected by a horizontally positioned pin 5. The clamping plate 2 is located below the axis of rotation. The clamp also includes a guide plate 4 located above the axis of rotation, and a connecting plate 3 connecting the clamping plate 2 and the guide plate 4. Both connecting plates 3 are rotatably connected to the pin 5 (e.g., ...). Figure 2 and Figure 3 (As shown); in the horizontal direction, the distance from the clamping plate 2 to the axis of the pin 5 is less than the distance from the guide plate 4 to the axis of the pin 5, so that the left and right opening and closing of the two clamping plates 2 can be adjusted by controlling the relative distance between the two guide plates 4; the cutting device for the glass coating machine also includes a drive mechanism for controlling the two clamping plates 2 to approach or separate. When cutting the coating, the usual practice is to insert the blade 10 directly into the gap between the front and rear glass and then move it horizontally to cut the connecting film in the middle. Since the glass plates are continuously and intermittently exported one by one in the production line, there is a gap between two adjacent glass plates that is greater than the thickness of the blade 10. Therefore, if only one blade 10 is used to cut, it is difficult to align the cut edge of the coating with the edge of the glass. Through the setting of the two clamps in this application, especially the setting of the two blades 10, the coating can be cut from the edge of the two glass at the same time, so that the coating is aligned with the edge of the glass and the cutting quality is improved.

[0034] In some embodiments, the mounting plate 1 is disposed on one side of the two clamping plates 2 facing away from each other, which facilitates the installation operation of the blade 10.

[0035] In some embodiments, the thickness of the two clamping plates 2 gradually decreases from top to bottom, which facilitates the adjustment of the angle of the two clamping plates 2 by means of the angle of the two guide plates 4. When the opposite sides of the two clamping plates 2 are in a vertical state, the two guide plates 4 are in a vertical state, and the distance between the sides of the two clamping plates 2 that are close to each other gradually increases from top to bottom, which facilitates the feedback of the distance between the two clamping plates 2 by means of the distance between the two guide plates 4.

[0036] In some embodiments, the drive mechanism includes a cylinder (not shown) disposed between two guide plates 4. The cylinder is configured to have a first state controlling the two guide plates 4 to move away from each other and a second state controlling the two guide plates 4 to move closer to each other. Specifically, the cylinder may be a finger cylinder, with its two grippers respectively connected to the two guide plates 4, and the cylinder body positioned above the two grippers. When the two grippers have not yet entered the gap between the two glass panes, the two grippers open, causing the two guide plates 4 to separate and the two grippers 2 to move closer together, facilitating smooth entry into the gap between the two glass panes. When the two grippers have begun to enter the gap between the two glass panes, the two grippers close, causing the two guide plates 4 to move closer and the two grippers 2 to separate and adhere tightly to the edge of the glass, facilitating alignment of the cut edge of the coating with the edge of the glass and improving the cutting quality. The separation and closing of the two grippers of the finger cylinder are controlled by a microcomputer.

[0037] In some embodiments, the cylinder is mounted on the frame 13. Specifically, the cylinder body is mounted on the frame 13. When the two clamps are located beside the glass plate, the two jaws of the cylinder contact the two guide plates 4 respectively, and the two jaws of the cylinder control the separation of the two guide plates 4, bringing the two clamping plates 2 closer together, until the two clamps begin to enter the gap between the two glass plates, at which point the jaws separate from the guide plates 4. The drive mechanism also includes a tension spring, the two ends of which are connected to the tops of the two guide plates 4 respectively. When the jaws separate from the guide plates 4, the tension spring can pull the two guide plates 4 closer together, causing the two clamping plates 2 to separate and fit tightly against the edge of the glass, facilitating the alignment of the cut edge of the film with the edge of the glass and improving the film cutting quality.

[0038] In some embodiments, such as Figures 1 to 3 As shown, the clamping plate 2 is also provided with two first mounting holes; the mounting plate 1 is provided with two second mounting holes at corresponding positions, and the connecting parts are two bolt and nut assemblies, with each bolt passing through the first and second mounting holes. Preferably, the bolts are butterfly screws 6 and the nuts are butterfly nuts, which facilitates disassembly and assembly and improves the convenience of operation.

[0039] In some embodiments, the fixing groove 7 is further provided with a slot 8 for placing a magnet block. For example, the slot 8 is circular and can accommodate a circular magnet block. The size of the magnet block can be selected as needed.

[0040] The assembly method of the cutting device for the glass coating machine of this utility model is as follows:

[0041] 1) Install the magnet block into slot 8;

[0042] 2) Assemble the blade 10 into the fixing groove 7 on the mounting plate 1. During assembly, pass the central hole of the blade 10 through the positioning post 9 and use the magnetic block to attract the blade 10 to prevent the blade 10 from falling off.

[0043] 3) Align the mounting holes of the steel sheet 11 with the positioning post 9 and install it on top of the blade 10. Use the magnet to attract the blade 10 and the steel sheet 11 to prevent them from falling off.

[0044] 4) Assemble the assembled mounting plate 1 onto the clamping plate 2, use the steel sheet 11 and pressure plate 12 to press the blade 10, and install the butterfly screw 6 and butterfly nut to fix the mounting plate 1 and clamping plate 2.

[0045] 5) Install the assembled glass coating machine with the cutting device on the guide rail 13 of the coating machine frame.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0047] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
