[0002] In the production of Western-style roof tiles, especially right-angled roof tiles, excess blank material often remains at the edges after the tiles are formed. This requires trimming to ensure that the product dimensions are compliant and the appearance is neat. Existing trimming methods mostly rely on manual operation or semi-automatic equipment, which has many shortcomings. The trimming efficiency is low and it is difficult to meet high production demands. The positioning accuracy of semi-automatic equipment is insufficient, which can easily lead to trimming deviations and affect product quality. Therefore, we propose a rapid trimming device for the production of right-angled roof tiles. Summary of the Invention

The bottom of the pressure plate is shaped to mimic the top of the tile. A guide sleeve is mounted at the top corner of the lower base, and a guide post is mounted at the bottom corner of the upper base. The upper base can be inserted into the guide post when it moves towards the guide sleeve.

[0005] Preferably, the lower template has an array of through holes arranged in the top of the inner side of the knife-avoiding groove, and its bottom is hollow and connected to the external negative pressure fan so that the top tiles can be suctioned and fixed. The top surface of the lower template and the bottom surface of the pressure plate are covered with urethane adhesive.

[0006] Preferably, a gantry frame is provided on the outer side of the lower base, and a hydraulic telescopic rod is installed on the top of the upper base, with the top of the hydraulic telescopic rod being fixedly connected to the top of the gantry frame.

[0007] Preferably, a collection box is provided on the rear side of the lower base, and a platform two is installed on the top front side. A fixing block is installed on the top side of the platform two near the lower template. A push rod is slidably connected to the fixing block, and a push block is installed at the end of the push rod. The movement of the push block can push the punched and trimmed tile out of the top of the lower template and into the collection box.

[0008] Preferably, a side plate is installed on the top left side of the lower base, and an array of rollers are rotatably connected between the inner sidewalls of the side plate.

[0009] Preferably, a support frame is provided on the left side of the lower base, and rollers are rotatably connected to both ends of the support frame. A conveyor belt is rotatably connected to the rollers. A baffle is installed in the middle of the top of the support frame. A horizontal plate is installed on one side of the baffle at the top of the support frame. A cylinder is installed at the top of the horizontal plate. The cylinder has a push rod. When the push rod moves, the tile blocked by the baffle can be pushed along the side wall of the baffle and onto the lower template at the top of the lower base through the top of the roller.

[0010] Preferably, a motor is mounted on the top of the second platform, and an eccentric wheel is mounted on the end of the output shaft of the motor.

[0013] This utility model has the following beneficial effects: 1. This quick-trimming device for producing right-angle roof tiles has a lower template installed in the center of the top of the lower base. A tile is placed on top of the lower template, and the top of the lower template matches the bottom of the tile in a contour-matching manner. The top of the lower template has cut-away grooves on all four sides of the tile's outline. A base is positioned directly above the tile, with an upper template installed in the center of the bottom of the base. The bottom of the upper template has four slanted grooves, each housing a cutting blade. A pressure plate is positioned below the upper template. Multiple guide shafts are slidably connected to the top of the upper base on both sides of the upper template. These guide shafts pass through the upper base and are fixedly connected to the pressure plate. Springs are placed on the guide shafts. A through-hole is located in the center of the pressure plate, allowing the upper template and cutting blades to pass through when the upper base presses down. The bottom of the pressure plate is shaped to resemble the top of the tile. The upper base drives the pressure plate, upper template, and cutting blades downwards, allowing the pressure plate to contact and press the tile firmly. The guide shafts and springs then allow the upper template and cutting blades to continue moving downwards to cut and trim the tile. The cutting blades, in conjunction with the avoidance grooves, enable fast and precise trimming, significantly improving production efficiency. Furthermore, the cutting blades can be installed in the four slanted grooves to accommodate different tile cutting needs (e.g., cutting only one or two sides), reducing blade loading time.

[0014] 2. This quick trimming device for right-angle sieve production has a guide sleeve installed at the top corner of the lower base and a guide post installed at the bottom corner of the upper base. The upper base can be inserted into the guide post when it is close to the guide sleeve of the lower base.

[0016] 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.

[0017] Please see Figures 1 to 2 This application provides a quick trimming device for right-angle tile production, including a lower base 6, a lower template 12 installed at the top center of the lower base 6, a tile 18 placed on the top of the lower template 12, the top of the lower template 12 and the bottom of the tile 18 being matched in shape, and the top of the lower template 12 having knife-avoiding grooves on the four sides of the outer shape of the tile 18. A top base 9 is positioned directly above the tile 18. An upper template 10 is installed in the center of the bottom of the top base 9. The bottom of the upper template 10 has four-sided cutting grooves, in which cutting blades 11 are installed. A pressure plate 27 is positioned below the upper template 10. Multiple guide shafts 20 are slidably connected to the top of the top base 9 on both sides of the upper template 10. The guide shafts 20 pass through the top base 9 and are fixedly connected to the pressure plate 27. Springs 21 are placed on the guide shafts 20. A through-hole is opened in the center of the pressure plate 27. The upper template 10 and the cutting blades 11 can pass through the through-hole when the top base 9 presses down on it. The bottom of the pressure plate 27 is shaped to resemble the top of the tile 18. A guide sleeve 7 is installed at the top corner of the lower base 6. A guide post 8 is installed at the bottom corner of the upper base 9. The upper base 9 can be inserted into the guide post 8 when it moves towards the guide sleeve 7.

[0018] Based on the above, the lower template 12 achieves the initial positioning of the tile 18 by conforming to the bottom of the tile 18, and the avoidance groove reserves the punching space for the punching blade 11; when the upper base 9 is pressed down, the guide shaft 20 and the spring 21 cooperate to make the pressure plate 27 contact the corner of the tile 18 first, and the edge of the tile 18 is pressed from above by the conforming pressure plate 27. Then the upper template 10 drives the punching blade 11 to pass through the opening of the pressure plate 27 and complete the punching of the excess blank at the edge of the tile 18 along the avoidance groove of the lower template 12; the guide post 8 and the guide sleeve 7 are precisely connected to ensure the coaxiality of the movement of the upper base 9 and the lower base 6 and avoid punching deviation; Furthermore, the contoured structure ensures stable positioning of the tile 18, and the pre-pressing and subsequent punching prevents displacement of the tile 18 during trimming; the punching blade 11 is independently installed in the four-sided blade groove, which can flexibly adapt to single-sided, double-sided, or four-sided trimming requirements, reducing blade change and adjustment time; the guide post 8 and guide sleeve 7 improve the motion accuracy of the equipment, ensure the consistency of the trimming dimensions of the tile 18, and reduce the defect rate.

[0019] Please see Figures 1 to 2The lower template 12 has an array of through holes on the top of the inner side of the knife-avoiding groove, and its bottom is hollow and connected to the external negative pressure fan so that the top tile 18 can be suctioned and fixed. The top of the lower template 12 and the bottom surface of the pressure plate 27 are covered with urethane adhesive.

[0020] Based on the above, the negative pressure is generated after the through hole of the lower template 12 is connected to the negative pressure fan, which sucks the tile 18 from the bottom and forms a two-way fixation with the upper clamping force of the pressure plate 27; the urethane coating is in direct contact with the surface of the tile 18, and buffers the impact force brought by hard contact through its own flexibility. Furthermore, negative pressure adsorption enhances the fixing effect of the tile 18, completely eliminating minor displacement during punching and further improving the trimming accuracy; the urethane adhesive can prevent the pressure plate 27 and the lower template 12 from causing scratches and indentations on the surface of the tile 18, protecting the integrity of the product appearance and reducing the breakage rate of finished products.

[0021] Please see Figures 1 to 2 A gantry frame 1 is provided on the outside of the lower base 6, and a hydraulic telescopic rod 5 is installed on the top of the upper base 9. The top of the hydraulic telescopic rod 5 is fixedly connected to the top of the gantry frame 1.

[0022] Based on the above, the gantry frame 1 provides a stable installation support for the hydraulic telescopic rod 5. The hydraulic telescopic rod 5 outputs a stable driving force through its telescopic action, which drives the upper base 9 to move up and down in the vertical direction, providing power for the pressure plate 27 to press and the punching knife to trim. Furthermore, the hydraulic drive provides stable power and the output force can be flexibly adjusted according to the thickness of the tile 18, adapting to the trimming needs of right-angle tiles of different specifications; the gantry frame 1 has high structural strength, which can avoid deformation caused by long-term operation of the equipment, extend the service life of the equipment, and ensure long-term operating accuracy.

[0023] Please see Figures 1 to 2 A collection box 19 is provided on the rear side of the lower base 6, and a platform 26 is installed on the top front side. A fixing block is installed on the top side of the platform 26 near the lower template 12. A push rod is slidably connected to the fixing block, and a push block 15 is installed at the end of the push rod. The push block 15 can be moved to push the punched and trimmed tile out of the top of the lower template 12 and into the collection box 19.

[0024] Based on the above, after the trimming is completed, the push rod slides along the fixed block to move the push block 15, pushing the finished tile 18 on the lower template 12 out of the template area. The tile 18 falls into the rear collection box 19 by its own weight and is automatically transferred after the trimming is completed. Furthermore, the elimination of manual material handling reduces human intervention and improves overall production efficiency; the collection box 19 centrally stores finished products, preventing damage caused by random stacking of tiles 18, and also facilitating subsequent unified handling and sorting.

[0025] Please see Figure 2 A side plate 16 is installed on the top left side of the lower base 6, and an array of rollers 17 are rotatably connected between the inner side walls of the side plate 16.

[0026] Based on the above, the side plate 16 limits and fixes the roller shaft 17 on both sides to prevent the roller shaft 17 from deviating; the roller shaft 17 guides the tile 18 smoothly from the conveying end to the template 12 by rotating itself, replacing sliding friction with rolling friction to reduce the moving resistance of the tile 18. Furthermore, rolling friction reduces frictional damage between the tile 18 and the equipment, ensuring the integrity of the tile 18 during the conveying process; the side plate 16 can prevent the tile from shifting to both sides during conveying, ensuring that the tile 18 accurately enters the positioning area of ​​the lower template 12 and improving the accuracy of feeding.

[0027] Please see Figures 1 to 3 A support frame 2 is provided on the left side of the lower base 6. Rollers are rotatably connected to both ends of the support frame 2. A conveyor belt 3 is rotatably connected to the rollers. A baffle 4 is installed in the middle of the top of the support frame 2. A horizontal plate is installed on one side of the baffle 4 on the top of the support frame 2. A cylinder 24 is installed on the top of the horizontal plate. The cylinder 24 has a push rod 25. The movement of the push rod 25 can push the tile blocked by the baffle 4 along the side wall of the baffle 4 through the top of the roller 17 onto the lower template 12 at the top of the lower base 6.

[0028] Based on the above, the support frame 2 provides installation support for the roller and the conveyor belt 3. The roller drives the conveyor belt 3 to realize the batch conveying of tiles 18. The baffle 4 limits the tiles on the conveyor belt 3 once to prevent multiple tiles 18 from stacking. The cylinder 24 drives the push rod 25 to push a single tile 18 along the side wall of the baffle 4 to the roller 17, and then the roller 17 guides it to the template 12 to complete the automatic feeding. Furthermore, the conveyor belt 3 enables continuous feeding of the tiles 18, adapting to the needs of large-scale production; the baffle 4 works in conjunction with the cylinder 24 to achieve precise pushing of a single tile, avoiding positioning confusion caused by feeding multiple tiles at the same time, improving feeding accuracy and efficiency, and reducing equipment downtime for adjustment.

[0029] Please see Figures 1 to 2 Platform 26 has a motor 13 mounted on top. An eccentric wheel 14 is mounted on the end of the output shaft of the motor 13. The eccentric wheel 14 is rotatably connected to a connecting rod on the side away from the center. The other end of the connecting rod is rotatably connected to a push rod.

[0030] Based on the above, motor 13 drives eccentric wheel 14 to rotate. Eccentric wheel 14 converts the rotational motion into the reciprocating linear motion of the connecting rod through the eccentric structure. The connecting rod drives the push rod to slide along the fixed block, providing continuous and stable power for push block 15 to push tile 18. Furthermore, the eccentric wheel 14 transmission structure is simple, has a low failure rate, and high reliability. It can achieve consistent stroke and force in the reciprocating motion of the push rod, ensuring stable material pushing effect each time. The motor drive replaces manual pushing, reducing manual labor intensity and improving material pushing efficiency, adapting to the automation rhythm of the equipment.

[0031] Please see Figures 1 to 3 Platform 22 is installed on one side of the end of support frame 2, and motor 23 is installed on the top of platform 22. The output shaft of motor 23 passes through the side wall of support frame 2 and is fixedly connected to one of the rollers.

[0032] Based on the above, platform 22 provides a stable installation position for motor 23 to prevent shaking when the motor is running; the output shaft of motor 23 directly drives the roller on the support frame to rotate, and the roller drives the roller to rotate, thereby driving the conveyor belt 3 to rotate, providing a power source for conveying the tile 18. Furthermore, motor 23 directly drives the roller, resulting in high transmission efficiency and reducing power loss in intermediate transmission links; platform 22 ensures stable motor installation, avoids motor vibration affecting the conveyor belt conveying accuracy, ensures that the tile 18 moves smoothly on the conveyor belt 3, and improves feeding stability.

[0033] Please see Figures 1 to 2 The cutting edge of the punch 11 is lower than the bottom surface of the pressure plate 27. When the upper base 9 is pressed down, the bottom surface of the pressure plate 27 first contacts the top surface of the corner of the tile 18.

[0034] Based on the above, during the pressing down of the upper base 9, because the height of the cutting blade 11 is lower than the bottom surface of the pressure plate 27, the pressure plate 27 will contact the edge surface of the tile 18 before the cutting blade 11. The tile 18 is pre-pressed through the contour structure of the pressure plate 27 and the elastic pressure of the spring 21. After the tile 18 is completely fixed, the upper base 9 continues to press down, and the cutting blade 11 passes through the opening of the pressure plate 27 to complete the trimming. Furthermore, the priority contact of the pressure plate ensures that the tile 18 is completely fixed before trimming, fundamentally avoiding trimming deviation caused by tile 18 displacement during punching and improving trimming accuracy; the spring 21 can buffer the clamping force of the pressure plate 27 to prevent excessive pressure from damaging the tile 18 blank and effectively improve the product qualification rate.

[0035] In summary, this rapid trimming device for right-angle sprue production operates by using a motor 23 to drive a roller on a support frame 2 via its output shaft. The roller drives a conveyor belt 3. The right-angle sprue blank to be trimmed is placed on the conveyor belt 3, which then transports the tile 18 towards the lower base 6. When the tile 18 reaches the baffle 4, the baffle 4 limits its movement to prevent multiple tiles from stacking or being transported ahead of schedule. A cylinder 24 on one side of the baffle 4 is activated, driving a push rod 25 to move horizontally. The push rod 25 then moves the single tile 18 blocked by the baffle 4. 8. The tile 18 is pushed along the side wall of the baffle 4 onto the roller 17 at the top of the lower base 6. The roller 17 rotates under the limitation of the side plate 16, reducing the resistance to the movement of the tile 18 by rolling friction, and smoothly conveying the tile 18 to the top of the lower template 12. At this time, the contour structure of the top of the lower template 12 and the bottom of the tile 18 achieves the initial positioning of the tile 18. The negative pressure fan is started, and the hollow structure at the bottom of the lower template 12 is connected to the negative pressure fan. The array of through holes at its top generates negative pressure, which firmly sucks the tile 18 from the bottom. At the same time, the hydraulic telescopic rod 5 on the gantry 1 is started, driving the upper base 9 to move downward. As the upper base 9 moves downward, the guide post 8 at the bottom of the upper base 9 is precisely inserted into the guide sleeve 7 at the top of the lower base 6, ensuring the coaxiality of the upper and lower bases. The upper base 9 continues to move downward, and because the cutting edge of the punching blade 11 is lower than the bottom surface of the pressure plate 27, the pressure plate contacts the top edge of the tile 18 before the punching blade. The contoured structure at the bottom of the pressure plate 27 fits against the top of the tile, and the spring 21 on the guide shaft 20 is compressed, generating elastic pressure to further press the tile 18 from above. As the upper base 9 continues to move downward, after the spring 21 is fully compressed, the upper template 10 drives the punching blade 11 through the opening in the middle of the pressure plate 27 and along the avoidance blade at the top of the lower template 12. The groove punches off excess blank material at the edge of the tile 18. If only part of the edge needs to be trimmed, it can be achieved by installing a separate punching cutter for the corresponding edge. After trimming, the hydraulic telescopic rod 5 drives the upper base 9 to reset, and the negative pressure fan stops working to release the tile 18 from the fixation. The motor 13 on the second platform 26 starts, and the motor output shaft drives the eccentric wheel 14 to rotate. The eccentric wheel drives the push rod to slide along the fixed block through the connecting rod. The push block 15 at the end of the push rod pushes the trimmed tile 18 out of the lower template 12. The pushed tile 18 slides down the rear side of the lower base 6 and falls into the collection box 19 to complete the collection.
