Description

Technical Field

[0001] This utility model relates to the field of glass trimming technology, specifically to a trimming tool for SGP laminated glass. Background Technology

[0002] With the continuous development of society and the continuous progress of technology, SGP laminated glass is being used more and more widely. SGP laminated glass has a high hardness, much greater than that of traditional laminated glass. During the production and processing of SGP laminated glass, edge trimming is required, which is usually done using glass trimming tools.

[0003] The document with publication number "CN209699152U" discloses a laminated glass trimming knife, which includes a fixed frame, a handle, a movable frame, a positioning pin and a blade. The handle is connected to one end of the fixed frame, and the movable frame is provided with reversing shafts on both opposite sides. The fixed frame is provided with two reversing shaft holes with corresponding positions, and the movable frame is disposed inside the fixed frame.

[0004] According to the aforementioned comparative documents, the current method for trimming SGP laminated glass is generally to have workers manually operate a small knife. The blade angle is inconvenient to adjust, and the blade cannot easily contact parts of the SGP laminated glass for trimming. The trimming process is also time-consuming, resulting in low efficiency in trimming SGP laminated glass.

[0005] To address this, we propose a trimming tool for SGP laminated glass. Utility Model Content

[0006] The purpose of this invention is to provide an SGP laminated glass trimming tool to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an SGP laminated glass trimming tool, comprising a handle, a mounting bracket fixedly mounted at the bottom of the handle, a rotating shaft rotatably connected to the middle of the handle, rotating plates located on both sides of the rotating shaft rotatably connected inside the handle, a rotating roller rotatably connected inside the mounting bracket, a blade holder integrally connected to the bottom of the rotating roller, a first sprocket fixedly mounted at the middle of the rotating roller, a scraper fixedly mounted at the bottom of the blade holder, and a tool located inside the handle fixedly mounted at the middle of the rotating shaft. The first and second sprockets are connected by a transmission chain. The rotating shaft is fixedly mounted with ratchet wheels on both sides of the second sprocket. The handle is rotatably connected to a pawl that abuts against the ratchet wheels. A button that slides through the handle is integrally connected to one side of the top of the rotating plate. A stop block is integrally connected to the other side of the top of the rotating plate. A sliding arc groove is formed at the bottom of the end of the stop block. The arc surface of the sliding arc groove slides in contact with one end of the pawl. An adjustment knob located outside the handle is fixedly mounted at one end of the rotating shaft.

[0008] Optionally, one end of the pawl is pressed against the ratchet, and a clamping spring is fixedly installed inside the grip above the pawl, with the other end of the clamping spring fixedly installed against the pawl.

[0009] Optionally, the two ratchet wheels rotate in opposite directions, the two pawls are opposite to the direction of the rotating plate, and the two ratchet wheels have the same dimensions.

[0010] Optionally, the outer peripheral surface of the grip has a through hole extending into the interior of the grip, and the button is slidably connected to the through hole. The button is an arc-shaped thick plate, and the inner diameter of the button is the same as the outer diameter of the grip.

[0011] Optionally, a pointer is provided on the side of the adjustment knob, and a circular scale is provided on the outer periphery of the grip.

[0012] Optionally, the contact surface between the rotating plate and the inside of the grip is provided with a matching limiting block and a limiting groove. When the button is not under force, the upper part of the rotating plate is in a vertical state. The thickness of the connection between the button and the rotating plate is the same as the width of the through hole.

[0013] Optionally, the scale is symmetrically arranged with the axis of the handle as the axis of symmetry, and the points where the scale coincides with the axis of the handle are marked as zero degrees and 180 degrees, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This SGP laminated glass trimming tool features a rotating roller. By pressing the button corresponding to the rotation direction, the rotating plate deflects, causing the clamping block to move. The contact end of the pawl with the sliding arc groove on the clamping block deflects, separating the pawl from the ratchet. The rotating shaft drives the second sprocket to rotate, which in turn drives the first sprocket via a transmission chain. This causes the rotating roller, which is fixedly mounted to the first sprocket, to rotate, adjusting the angle of the blade holder and scraper. After adjustment, releasing the button causes the pawl to engage with the ratchet under the action of the clamping spring, preventing the rotating shaft and the two sprockets from rotating. This allows for adaptive adjustment of the blade angle, facilitating subsequent contact between the blade and a portion of the SGP laminated glass for trimming. The operation is more convenient, the trimming time is shorter, and the trimming efficiency of SGP laminated glass is high.

[0016] This SGP laminated glass trimming tool features an adjustment knob and scale. When the button is pressed, rotating the adjustment knob causes the shaft to rotate, which in turn causes the ratchet and second sprocket, which are fixed to the shaft, to rotate. This allows the scraper to rotate to the appropriate angle. After rotation, the pointer and scale on the adjustment knob can indicate the rotation angle of the scraper, so that the angle can be adjusted directly for the next use. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1 to 5 This utility model provides an SGP laminated glass trimming tool, including a handle 1, a mounting bracket 2 fixedly installed at the bottom of the handle 1, a rotating shaft 8 rotatably connected to the middle of the handle 1, rotating plates 12 located on both sides of the rotating shaft 8 rotatably connected inside the handle 1, a rotating roller 3 rotatably connected inside the mounting bracket 2, a blade holder 4 integrally connected to the bottom of the rotating roller 3, a first sprocket 6 fixedly installed at the middle of the rotating roller 3, a scraper 5 fixedly installed at the bottom of the blade holder 4, and a positioning... The second sprocket 9 is located inside the grip 1. The first sprocket 6 and the second sprocket 9 are connected by a transmission chain 7. A ratchet 10 located on both sides of the second sprocket 9 is fixedly installed on the rotating shaft 8. A pawl 14 that abuts against the ratchet 10 is rotatably connected inside the grip 1. A button 16 that slides through the grip 1 is integrally connected to one side of the top of the rotating plate 12. A retaining block 13 is integrally connected to the other side of the top of the rotating plate 12. A sliding arc groove 15 is formed at the bottom of the end of the retaining block 13. The curved surface slides in contact with one end of the pawl 14. One end of the rotating shaft 8 is fixedly installed with an adjustment knob 11 located outside the handle 1. By setting the rotating roller 3 and pressing the button 16 corresponding to the rotation direction, the rotating plate 12 is deflected, thereby moving the clamping block 13. The contact end of the pawl 14 and the sliding arc groove 15 on the clamping block 13 is deflected, thereby separating the pawl 14 from the ratchet 10. Rotating the rotating shaft 8 drives the second sprocket 9 to rotate, which drives the first sprocket 6 to rotate through the transmission chain 7, thereby causing the rotating roller 3 fixedly installed with the first sprocket 6 to rotate. This is used to adjust the angle of the blade holder 4 and the scraper 5. After adjustment, the button 16 is released. Under the action of the clamping spring 17, the pawl 14 and the ratchet 10 are engaged, preventing the rotating shaft 8 and the two sprockets from rotating. The angle of the blade can be adjusted adaptively. The blade can then easily contact a part of the SGP laminated glass for edge trimming, making the operation more convenient and the trimming time shorter, resulting in higher efficiency in trimming SGP laminated glass.

[0025] One end of the pawl 14 abuts against the ratchet 10. A retaining spring 17 is fixedly installed inside the grip 1, positioned above the pawl 14. The other end of the retaining spring 17 is fixedly installed against the pawl 14. The two ratchet wheels 10 rotate in opposite directions, and the two pawls 14 rotate in the opposite direction to the rotating plate 12. The two ratchet wheels 10 have the same dimensions. A through hole extending into the grip 1 is provided on the outer circumference of the grip 1. A button 16 is slidably connected to the through hole. The button 16 is an arc-shaped thick plate, and its inner diameter is the same as the outer diameter of the grip 1. A pointer is provided on the side of the adjusting knob 11. A circular scale 18 is provided on the outer circumference of the grip 1. Matching limit blocks and limit grooves are provided on the contact surface between the rotating plate 12 and the inside of the grip 1. When the button 16 is not under force, the upper part of the plate 12 is in a vertical position. The thickness of the connection between the button 16 and the rotating plate 12 is the same as the width of the through hole. The scale 18 is symmetrically set with the axis of the handle 1 as the axis of symmetry. The points where the scale 18 and the axis of the handle 1 coincide are marked as zero degrees and 180 degrees, respectively. By setting the adjustment knob 11 and the scale 18, when the button 16 is pressed, the adjustment knob 11 is rotated, which causes the rotating shaft 8 to rotate. This causes the ratchet 10 and the second sprocket 9, which are fixedly installed with the rotating shaft 8, to rotate, so that the angle of the scraper 5 is rotated to a suitable angle. After the rotation is completed, the rotation angle of the scraper 5 can be indicated by the pointer on the adjustment knob 11 and the scale 18, so that the angle can be directly adjusted next time.

[0026] Working principle:

[0027] Pressing button 16 corresponding to the rotation direction causes the rotating plate 12 to deflect, thereby moving the clamping block 13. The contact end of the pawl 14 and the sliding arc groove 15 on the clamping block 13 deflects, thus separating the pawl 14 from the ratchet 10. Rotating the shaft 8 drives the second sprocket 9 to rotate, which in turn drives the first sprocket 6 to rotate via the transmission chain 7. This causes the rotating roller 3, which is fixedly installed with the first sprocket 6, to rotate, adjusting the angle of the tool holder 4 and the scraper 5. After adjustment, releasing button 16 causes the pawl 14 to engage with the ratchet 10 under the action of the clamping spring 17, preventing... The rotation of the shaft 8 and the two sprockets allows for adaptive adjustment of the blade angle, facilitating subsequent contact and trimming of the SGP laminated glass. When button 16 is pressed, the adjustment knob 11 is rotated, causing the shaft 8 to rotate. This, in turn, causes the ratchet 10 and the second sprocket 9, which are fixedly mounted on the shaft 8, to rotate, adjusting the angle of the scraper 5 to a suitable angle. After rotation, the pointer and scale 18 on the adjustment knob 11 can indicate the rotation angle of the scraper 5, allowing for direct angle adjustment during the next use.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
