Description

Technical Field

[0001] This application relates to the technical field of safety glass production equipment, and in particular to a trimming device for safety glass production. Background Technology

[0002] Laminated glass is commonly used as safety glass in building curtain walls, plazas, and other applications. It can also be used as bulletproof glass or in other industrial applications.

[0003] In related technologies, laminated glass generally consists of two pieces of glass, one at the top and one at the bottom, and an interlayer film between the two pieces of glass. The two pieces of glass clamp the interlayer film together and are processed through special high-temperature pre-pressing and high-temperature and high-pressure processes to permanently bond the two pieces of glass and the interlayer film together.

[0004] In the production of laminated glass, the area of ​​the interlayer film is usually larger than the surface area of ​​the two glass panes. The edges of the interlayer film extend from the edges of the two glass panes to cover the entire surface of the glass. Then, workers use cutting tools such as blades to remove the excess interlayer film. The glass is generally placed on a conveyor belt for horizontal transport, and the width of the glass is greater than the width of the conveyor belt, so that both sides of the glass and the interlayer film protrude from the sides of the conveyor belt, facilitating the workers' removal of excess interlayer film.

[0005] Regarding the aforementioned technologies, the inventors believe that the interlayer membrane is soft, and the operation of cutting off excess interlayer membrane using cutting tools is cumbersome and easily results in uneven cutting of the interlayer membrane, requiring repeated cutting and trimming, which leads to low production efficiency. Summary of the Invention

[0006] In order to facilitate the removal of excess interlayer film and thus improve the production efficiency of laminated glass, this application provides a trimming device for the production of safety glass.

[0007] This application provides a trimming device for safety glass production, which adopts the following technical solution: A trimming device for safety glass production, comprising: A side-cutting mechanism is used to remove excess edge material on opposite sides of the interlayer film. The side-cutting mechanism includes a first support member, a first cutting part, and a second cutting part. The first cutting part and the second cutting part are slidably connected to the first support member, and the first cutting part and the second cutting part are disposed on both sides of the laminated glass to be trimmed for cutting off excess edge material on opposite sides of the interlayer film respectively. An end-cutting mechanism is located behind the side-cutting mechanism and is used to remove excess edge material at opposite ends of the intermediate film. The end-cutting mechanism includes a second support member and a third cutting part. The second support member is parallel to the first support member, and the third cutting part is slidably connected to the second support member for cutting off excess edge material at opposite ends of the intermediate film.

[0008] By adopting the above technical solution, when edge trimming of laminated glass is required, the side cutting mechanism removes excess edge material from both sides of the interlayer film, and the end cutting mechanism removes excess edge material from both ends of the interlayer film, thereby achieving complete removal of excess edge material from the interlayer film. During the removal of excess edge material from both sides of the interlayer film, the first support member supports the first and second cutting sections, which are located on both sides of the laminated glass. As the laminated glass moves on the conveyor belt, the first and second cutting sections automatically cut off the excess edge material from both sides of the interlayer film. Both the first and second cutting sections are slidably connected to the first support member, allowing the distance between them to be adjusted. This makes it suitable for removing excess edge material from the side interlayer film of laminated glass of different widths. This design improves applicability. During the removal of excess edge material at both ends of the interlayer film, the second support supports the third cutting section. The laminated glass stops at the cutting points at both ends of the interlayer film as it is conveyed by the conveyor belt. When the laminated glass stops moving, the third cutting section is positioned above one end of the interlayer film. Then, as the third cutting section moves on the second support, it cuts off the excess edge material at one end of the interlayer film. The laminated glass continues to move until the third cutting section is positioned above the other end of the interlayer film, at which point it stops moving again. The third cutting section then moves on the second support to cut off the excess edge material at the other end of the interlayer film, thus achieving the removal of excess edge material at both ends of the interlayer film. The entire cutting and trimming operation of the laminated glass is simple and quick, requiring no manual operation and exhibiting a high degree of automation. Furthermore, it eliminates the need for repeated manual cutting and trimming, which helps improve the production efficiency of laminated glass.

[0009] Preferably, the first cutting section, the second cutting section, and the third cutting section each include a mounting plate, a blade assembly, and a first driving assembly. The mounting plate is movably connected to the first support member or the second support member. The blade assembly is mounted on the mounting plate for cutting the intermediate film. The first driving assembly is mounted on the mounting plate for driving the blade assembly to move in the vertical direction.

[0010] By adopting the above technical solution, when the conveyor belt transports the laminated glass, the first drive assembly in the first and second cutting sections drives the mounting plate to move vertically downward, so that the blades in the first and second cutting sections are respectively aligned with the cutting points on opposite sides of the interlayer film. As the laminated glass moves on the conveyor belt, the blades in the first and second cutting sections cut off the excess edge material on opposite sides of the interlayer film, thereby removing the excess edge material on opposite sides of the interlayer film. When the conveyor belt moves the laminated glass to a position where the third cutting section is above the end of the interlayer film, the first drive assembly in the third cutting section drives the mounting plate to move vertically downward, so that the blades in the third cutting section are aligned with the cutting points at the end of the interlayer film. As the third cutting section moves on the second support member, the blades in the third cutting section cut off the excess edge material at the end of the interlayer film, thereby removing the excess edge material at opposite ends of the interlayer film.

[0011] Preferably, the blade assembly includes a mounting base and a blade, the blade being detachably connected to the mounting base, with the cutting edge of the blade facing the position of the intermediate membrane to be cut.

[0012] By adopting the above technical solution, the mounting base supports the blade, and the blade is detachably connected to the mounting base to facilitate the replacement operation of the blade by the operator. In the first and second cutting sections, as the laminated glass moves on the conveyor belt, the blade edge faces the positions to be cut on opposite sides of the interlayer film to remove the excess edge material on opposite sides of the interlayer film. In the third cutting section, as the third cutting section moves on the second support, the blade edge faces the positions to be cut at both ends of the interlayer film to remove the excess edge material at opposite ends of the interlayer film.

[0013] Preferably, each set of blades contains two blades, with the cutting edges of the two blades facing away from each other and the bottom ends of the two blades being pointed.

[0014] By adopting the above technical solution, since the intermediate film is soft, when the first driving component drives the blade assembly to move vertically downward, the bottom end of the blade is set at a sharp angle to facilitate the blade to insert into the intermediate film, so as to facilitate the blade to cut off the excess edge material of the intermediate film.

[0015] Preferably, the first cutting section, the second cutting section, and the third cutting section all further include a second driving component for driving the blade to move in the horizontal direction, the second driving component driving the blade to move along the trajectory direction of the intermediate film to be cut.

[0016] By adopting the above technical solution, in the first and second cutting sections, when the two blades are inserted into the interlayer film, the second driving member drives the two blades to move along the trajectory to be cut on the interlayer film. The blade facing the cutting point of the interlayer film cuts off one end of the excess edge material on both sides of the interlayer film. Then, as the laminated glass moves on the conveyor belt, the other blade cuts off the other end of the excess edge material on both sides of the interlayer film, thereby facilitating the removal of the excess edge material on both sides of the interlayer film. In the third cutting section, when the two blades are inserted into the interlayer film, the second driving member drives the two blades to move along the trajectory to be cut on the interlayer film. The blade facing the cutting point of the interlayer film cuts off one end of the excess edge material on both ends of the interlayer film. Then, as the third cutting section moves on the second support member, the other blade cuts off the other end of the excess edge material on both ends of the interlayer film, thereby facilitating the removal of the excess edge material on both ends of the interlayer film.

[0017] Preferably, the first driving component includes a placement plate, a first connecting plate, and a first driving member. The placement plate is fixedly disposed on the mounting plate, the first driving member is fixedly disposed on the placement plate for driving the first connecting plate to move vertically up and down, the first connecting plate is slidably connected to the mounting plate, and the mounting base is connected to the first connecting plate.

[0018] By adopting the above technical solution, the placement plate supports the first support member, the first driving member drives the first connecting plate to move vertically up and down, the mounting base is connected to the first connecting plate so that the vertical up and down movement of the first connecting plate can drive the mounting base to move vertically up and down, and the blade assembly is connected to the mounting base, thereby realizing the vertical up and down movement of the blade assembly to cut off the excess edge material of the intermediate film.

[0019] Preferably, the first connecting plate is provided with a third driving component for driving the blade to continue to move vertically up and down. The third driving component includes a third connecting plate and a third driving member. The third driving member is fixedly disposed on the first connecting plate for driving the third connecting plate to slide vertically up and down and connect to the first connecting plate. The mounting base is connected to the third connecting plate.

[0020] By adopting the above technical solution, the third driving component can drive the third connecting plate to slide vertically up and down on the first connecting plate, and the mounting base is connected to the third connecting plate, so that the mounting base can continue to move in the vertical direction. The third driving component drives the blade to continue to move in the vertical direction, which is beneficial to increasing the range of movement of the blade in the vertical direction.

[0021] Preferably, the second driving assembly includes a second connecting plate and a second driving member. The second driving member is fixedly disposed on the third connecting plate. One end of the second connecting plate is fixedly connected to the second driving member, and the other end of the second connecting plate is fixedly connected to the mounting base. The second driving member is used to drive the second connecting plate to move in the horizontal direction, and the mounting base is horizontally slidably connected to the third connecting plate.

[0022] By adopting the above technical solution, when the two blades are inserted into the interlayer film, the second driving member drives the mounting base to slide horizontally on the third connecting plate. The mounting base drives the blades to move along the cutting trajectory of the interlayer film, so that one blade can cut off one end of the interlayer film relative to the two sides of the excess edge material. In the first and second cutting sections, the movement direction of the laminated glass on the conveyor belt is opposite to the driving direction of the second driving member. The other blade cuts off the other end of the interlayer film relative to the two sides of the excess edge material, thereby realizing the removal operation of the interlayer film relative to the two sides of the excess edge material. In the third cutting section, the movement direction of the third cutting section on the second support member is opposite to the driving direction of the second driving member. The other blade cuts off the other end of the excess edge material at the end of the interlayer film, thereby realizing the removal operation of the interlayer film relative to the two ends of the excess edge material.

[0023] Preferably, the mounting base is provided with a separation post, which is located between the two blades, and the bottom surface of the separation post is higher than the bottom end of the blade.

[0024] By adopting the above technical solution, the separation column separates the cut-off excess intermediate membrane from the blade, which helps to prevent the cut-off intermediate membrane from getting tangled on the blade and hindering the blade's cutting operation.

[0025] Preferably, the mounting plate is rotatably provided with a protective cover assembly for covering the blade. The protective cover assembly includes a protective cover and a fourth driving member, which drives the protective cover to rotate up and down and is connected to the mounting plate.

[0026] By adopting the above technical solution, the protective cover assembly covers the blade to provide protection and isolation, which helps to prevent external impurities from falling into the first cutting section, the second cutting section and the third cutting section. The fourth driving component drives the protective cover to rotate up and down and is connected to the mounting plate, which facilitates the replacement of the blade by the operator.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a side cutting mechanism and an end cutting mechanism, when it is necessary to trim the laminated glass, the side cutting mechanism removes the excess edge material on both sides of the interlayer film, and the end cutting mechanism removes the excess edge material on both ends of the interlayer film. The entire trimming operation of the laminated glass is simple and quick, requires no manual operation, has a high degree of automation, and does not require repeated manual cutting and trimming, which helps to improve the production efficiency of laminated glass.

[0028] 2. By setting two blades in each blade group, when the first drive assembly drives the blade group to move vertically downward, the bottom end of the blade is set at a sharp angle to facilitate the blade insertion into the intermediate film. The blade edges of the two blades are set in opposite directions so that when the blades move in opposite directions, they can cut off the excess edge material on one side of the intermediate film, so as to facilitate the cutting operation of the excess edge material of the intermediate film.

[0029] 3. By setting a separation column, the excess intermediate film cut off is separated from the blade, which helps to prevent the cut intermediate film from getting tangled on the blade and hindering the blade's cutting operation. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0035] This application discloses a trimming device for safety glass production, used to trim laminated glass being conveyed on a conveyor belt. (Refer to...) Figure 1 The device includes a side cutting mechanism 1 and an end cutting mechanism 2. The side cutting mechanism 1 is installed on the conveyor belt to remove excess edge material on both sides of the intermediate film. The end cutting mechanism 2 is installed on the conveyor belt to remove excess edge material at both ends of the intermediate film. In this embodiment, the end cutting mechanism 2 is located behind the side cutting mechanism 1 in the conveying direction of the conveyor belt, so that the side cutting mechanism 1 removes the excess edge material on both sides of the intermediate film first, and the end cutting mechanism 2 removes the excess edge material at both ends of the intermediate film.

[0036] Reference Figure 1 The side-cutting mechanism 1 includes a first support member 11, a first cutting part 12, and a second cutting part 13. Both the first cutting part 12 and the second cutting part 13 are slidably connected to the first support member 11, and are respectively located on both sides of the laminated glass to be trimmed for cutting excess edge material on opposite sides of the interlayer film. The end-cutting mechanism 2 includes a second support member 21 and a third cutting part 22. The second support member 21 is parallel to the first support member 11, and the third cutting part 22 is slidably connected to the second support member 21 for cutting excess edge material at opposite ends of the interlayer film. In this embodiment, the first support member 11 is configured as a first support frame, and the second support member 21 is configured as a second support frame. Both the first and second support frames are installed in an arch shape on the conveyor belt's conveying path. The second support frame is parallel to the first support frame and is located behind the first support frame relative to the conveyor belt's conveying direction.

[0037] As the laminated glass passes the first support frame, the first cutting section 12 and the second cutting section 13, located on both sides of the laminated glass, cut the opposite sides of the interlayer film to remove excess material. It should be noted that the first cutting section 12 and the second cutting section 13 are slidably connected to the first support frame, allowing for adjustment of the distance between them. This enables the removal of excess material from the interlayer film on laminated glass of different widths. When one end of the laminated glass reaches the position of the second support frame, the glass stops moving, and the third cutting section 22 moves on the second support frame to remove excess material from one end of the interlayer film. The conveyor belt then continues to move the laminated glass. When the other end of the laminated glass reaches the position of the second support frame, the glass stops moving, and the third cutting section 22 moves again on the second support frame to remove excess material from the other end of the interlayer film, thus completing the entire trimming operation of the interlayer film.

[0038] Reference Figure 1 and Figure 2 The first cutting section 12, the second cutting section 13, and the third cutting section 22 each include a mounting plate 3, a blade assembly 4, and a first drive assembly 5. The mounting plate 3 is vertically arranged, and the blade assembly 4 and the first drive assembly 5 are respectively located on both sides of the mounting plate 3. The mounting plate 3 separates the first drive assembly 5 and the blade assembly 4 to prevent the driving operation of the first drive assembly 5 from interfering with the cutting operation of the blade assembly 4. Specifically, in the first cutting section 12 and the second cutting section 13, the mounting plate 3 is movably connected to the first support frame along the length direction of the first support frame. The blade assembly 4 is mounted on the mounting plate 3 for cutting excess edge material on opposite sides of the intermediate film. The first drive assembly 5 is mounted on the mounting plate 3 for driving the blade assembly 4 to move vertically. In the third cutting section 22, the mounting plate 3 is movably connected to the second support frame along the length direction of the second support frame. The blade assembly 4 is mounted on the mounting plate 3 for cutting excess edge material on opposite ends of the intermediate film. The first drive assembly 5 is mounted on the mounting plate 3 for driving the blade assembly 4 to move vertically.

[0039] Reference Figure 1 and Figure 2 The first driving assembly 5 includes a placement plate 51, a first connecting plate 52, and a first driving component 53. The placement plate 51 is horizontally fixed to one side wall of the mounting plate 3 by bolts. The first driving component 53 is fixedly mounted on the placement plate 51 and is used to drive the first connecting plate 52 to move vertically up and down. The first connecting plate 52 slides vertically up and down and is connected to the mounting plate 3. The blade assembly 4 is connected to the first connecting plate 52. This allows the blade assembly 4 to move vertically up and down under the drive of the first driving component 53.

[0040] Reference Figure 2 and Figure 3The first driving component 53 includes a first driving motor 531 and a screw 532. The first driving motor 531 is vertically arranged, and the output shaft of the first driving motor 531 is vertically downward. The screw 532 is coaxially fixedly connected to the output shaft of the first driving motor 531. The first connecting plate 52 includes a first horizontal plate 521 and a first vertical plate 522 that are vertically fixedly connected. The first drive motor 531 is fixedly mounted on the upper surface of the placement plate 51. The output shaft of the first drive motor 531 and the screw 532 rotate through the placement plate 51, and the screw 532 is threaded through the first horizontal plate 521. The surface of the first vertical plate 522 abuts against and slides on the surface of the mounting plate 3. When the first drive motor 531 is started, the output shaft of the first drive motor 531 drives the screw 532 to rotate. The screw 532 is threaded through the first horizontal plate 521, and the surface of the first vertical plate 522 abuts against and slides on the surface of the mounting plate 3, so that the first horizontal plate 521 and the first vertical plate 522 move vertically up and down with the rotation of the screw 532, thereby driving the knife assembly 4 to move vertically up and down. It is worth mentioning that a sleeve 10 is vertically fixed through the first horizontal plate 521, and the screw 532 is threaded through the sleeve 10. The sleeve 10 increases the contact area between the screw 532 and the first horizontal plate 521, so as to improve the stability when the screw 532 drives the first horizontal plate 521 to move vertically up and down.

[0041] Reference Figure 2 The first connecting plate 52 is provided with a third driving assembly 7 for driving the blade assembly 4 to continue moving vertically up and down. Specifically, the third driving assembly 7 includes a third connecting plate 71 and a third driving member 72. The third driving member 72 is fixedly disposed on the first connecting plate 52 and is used to drive the third connecting plate 71 to slide vertically up and down and connect to the first connecting plate 52. The blade assembly 4 is connected to the third connecting plate 71. In this embodiment, the third driving member 72 is configured as a third driving cylinder. The third driving cylinder is vertically fixedly disposed on the upper surface of the first horizontal plate 521. The piston rod of the third driving cylinder moves through the first horizontal plate 521. The third connecting plate 71 includes a third horizontal plate 711 and a third vertical plate 712 that are vertically fixedly connected. The piston rod of the third driving cylinder is vertically fixedly connected to the third horizontal plate 711. The third vertical plate 712 slides vertically up and down and connects to the surface of the first vertical plate 522. The blade assembly 4 is connected to the third vertical plate 712. The extension or retraction of the piston rod of the third drive cylinder causes the third horizontal plate 711 and the third vertical plate 712 to move vertically up and down, thereby driving the tool assembly 4 to continue to move vertically up and down.

[0042] Reference Figure 1 and Figure 2The blade assembly 4 includes a mounting base 41 and blades 42. The mounting base 41 is connected to the surface of the third vertical plate 712, allowing the third vertical plate 712 to move vertically up and down under the drive of the first drive motor 531 and the third drive cylinder. The blades 42 are vertically arranged and detachably connected to the mounting base 41 for easy replacement by the operator. The cutting edge of the blades 42 faces the position to be cut in the intermediate film. It should be noted that each blade assembly 4 contains two blades 42 with their cutting edges facing away from each other, allowing them to move in opposite directions to cut off excess material from the intermediate film. Both blades 42 have pointed bottoms to facilitate insertion into the intermediate film. (Refer to...) Figure 3 The first cutting section 12, the second cutting section 13 and the third cutting section 22 each include a second driving component 6 for driving the blade 42 to move in the horizontal direction. The second driving component 6 drives the blade 42 to move along the trajectory direction of the intermediate film to be cut.

[0043] Reference Figure 2 and Figure 3 The second drive assembly 6 includes a second connecting plate 61 and a second drive member 62. In this embodiment, the second drive member 62 is configured as a second drive cylinder. The second drive cylinder is horizontally fixedly disposed on the surface of the third vertical plate 712. One end of the second connecting plate 61 is fixedly connected to the piston rod of the second drive cylinder, and the other end of the second connecting plate 61 is fixedly connected to the mounting base 41. The extension and retraction of the piston rod of the second drive cylinder can drive the second connecting plate 61 to move the mounting base 41 in the horizontal direction, and the mounting base 41 is horizontally slidably connected to the third connecting plate 71.

[0044] In the first cutting section 12 and the second cutting section 13, the two blades 42 in the blade assembly 4 are located on the cutting paths on opposite sides of the interlayer film. When the laminated glass flows through the first support frame, the first drive motor 531 and the third drive cylinder drive the mounting base 41 to move vertically downward, so that the two blades 42 are inserted into the positions to be cut on opposite sides of the interlayer film. Then, the second drive cylinder drives the mounting base 41 to move in the same direction as the conveying direction of the laminated glass, so that one blade 42 cuts off one end of the excess edge material on opposite sides of the interlayer film during the movement. Then, as the laminated glass is conveyed on the conveyor belt, the other blade 42 cuts off the other end of the excess edge material on opposite sides of the interlayer film, thereby realizing the removal of excess edge material on opposite sides of the interlayer film.

[0045] In the third cutting section 22, the blade 42 in the third cutting section 22 is set perpendicular to the blade 42 in the first cutting section 12. When the conveyor belt transports one end of the laminated glass to the bottom of the second support frame, the first drive motor 531 and the third drive cylinder drive the mounting base 41 to move vertically downward, so that the two blades 42 are inserted into the cutting position at one end of the interlayer film. Then, the second drive cylinder drives the mounting base 41 to move in the width direction of the laminated glass, so that one blade 42 cuts off one end of the excess edge material at the end of the interlayer film during the movement. Then, the mounting plate 3 moves along the length direction of the second support frame, so that the other blade 42 cuts off the other end of the excess edge material at the end of the interlayer film, thereby realizing the removal of the excess edge material at the end of the interlayer film. The removal of the excess edge material at the other end of the interlayer film is the same as the above operation, and will not be described in detail here.

[0046] Reference Figure 2 and Figure 3 Each mounting base 41 is provided with a separation column 8. In this embodiment, each mounting base 41 is provided with two separation columns 8. The two separation columns 8 are located between the two blades 42 and are close to the two blades 42 respectively, and the bottom surface of the separation column 8 is higher than the bottom end of the blade 42. During the process of the blade 42 cutting the intermediate film, the separation column 8 close to the blade 42 separates the cut intermediate film edge material from the blade 42 to prevent the cut intermediate film edge material from getting tangled on the blade 42.

[0047] Reference Figure 2 and Figure 3 The mounting plate 3 is rotatably equipped with a protective cover assembly 9 for covering the blade 42. Specifically, the protective cover assembly 9 includes a protective cover 91 and a fourth drive member 92. The protective cover 91 is rotatably connected to the upper end of the mounting plate 3. The fourth drive member 92 includes a fourth drive cylinder 921 and a sliding plate 922. The fourth drive cylinder 921 is hinged to the side wall of the mounting plate 3, and the sliding plate 922 is hinged to the piston rod of the fourth drive cylinder 921. The sliding plate 922 is slidably connected to the inner side wall of the protective cover 91 away from the mounting plate 3. In addition, the protective cover... A guide groove 14 is vertically provided on the inner side wall away from the mounting plate 3, so that the extension or retraction of the fourth drive cylinder 921 can drive the protective cover 91 to flip up and down through the sliding plate 922. When the piston rod of the fourth drive cylinder 921 is extended, the protective cover 91 flips upward to facilitate the replacement operation of the blade 42 by the operator. When the piston rod of the fourth drive cylinder 921 is retracted, the protective cover 91 flips downward and covers the blade 42 to prevent external impurities from falling into the protective cover 91 and interfering with the cutting operation of the blade 42.

[0048] The implementation principle of a trimming device for safety glass production according to an embodiment of this application is as follows: When trimming of the interlayer of laminated glass is required, the laminated glass is placed on a conveyor belt for conveying. When the laminated glass passes the first support frame, the first drive motor 531 and the third drive cylinder in the first cutting part 12 and the second cutting part 13 drive the blade 42 to move vertically downward, so that the blade 42 inserts into the positions to be cut on opposite sides of the interlayer. Then, the second drive cylinder drives the mounting base 41 to move in the same direction as the conveying direction of the laminated glass, so that one blade 42 cuts off one end of the excess edge material on opposite sides of the interlayer during the movement. Then, as the laminated glass is conveyed on the conveyor belt, the other blade 42 cuts off the other end of the excess edge material on opposite sides of the interlayer, thereby realizing the removal of the excess edge material on opposite sides of the interlayer. When the conveyor belt conveys one end of the laminated glass to the bottom of the second support frame... At the same time, the first drive motor 531 and the third drive cylinder in the third cutting section 22 drive the mounting base 41 to move vertically downward, so that the two blades 42 are inserted into the cutting position at one end of the interlayer film. Then, the second drive cylinder drives the mounting base 41 to move in the width direction of the laminated glass, so that one blade 42 cuts off one end of the excess edge material at the end of the interlayer film during the movement. Then, the mounting plate 3 moves along the length direction of the second support frame, so that the other blade 42 cuts off the other end of the excess edge material at the end of the interlayer film, thereby realizing the removal of the excess edge material at one end of the interlayer film. When the conveyor belt transports the other end of the laminated glass to the bottom of the second support frame, the above operation is repeated to realize the removal of the excess edge material at the other end of the interlayer film. The entire cutting and trimming operation of the laminated glass is simple and quick, requires no manual operation, has a high degree of automation, and does not require repeated manual cutting and trimming, which is conducive to improving the production efficiency of laminated glass.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
