Description

Technical Field

[0001] The utility model relates to a sheet cutting machine, which belongs to the technical field of thermoplastic sheet processing equipment. Background Art

[0002] In the production line of thermoplastic extrusion sheets, the precise cutting of sheets is a key link to ensure product quality and production efficiency. However, during the conveying process of existing sheets, due to the lack of effective positioning and correction mechanisms, the sheets are prone to deviation, resulting in inaccurate cutting positions. The deviation of the sheets not only affects the cutting accuracy, but also may increase the scrap rate of products, increasing the production cost. Traditional cutting machines are highly dependent on the position of the sheets. Once the position of the sheets deviates, it is necessary to stop the machine for manual adjustment. Manual adjustment is not only time-consuming, but also increases the labor intensity of operators, and cannot achieve a continuous and efficient production process, seriously affecting the production efficiency. Therefore, it is necessary to improve the cutting machine by automatically and precisely correcting the position of the sheets. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a sheet cutting machine to solve the problems mentioned in the above background art.

[0004] To achieve the above purpose, the utility model is realized by the following technical solutions: A sheet cutting machine includes a cutting frame, a front conveying roller frame arranged on the front side of the cutting frame, and a rear conveyor belt installed on the rear side of the cutting frame. It is characterized in that a cutting mechanism is arranged in the middle of the cutting frame, and a correction component for pushing the sheet to move left and right is arranged above the front conveying roller frame;

[0005] The correction component includes vertical plates installed on the left and right sides of the front conveying roller frame. A right movable push plate and a left movable push plate are movably arranged between the two vertical plates. An assembly screw rod and a guide rod are installed between the two vertical plates, and both the assembly screw rod and the guide rod penetrate through the middle parts of the right movable push plate and the left movable push plate. A first motor and a second motor for controlling the rotation of the assembly screw rod are respectively installed on the outer sides of the two vertical plates. An infrared detection rod is also installed between the two vertical plates, and the infrared detection rod is located below the right movable push plate and the left movable push plate, and the push rod is staggered with the infrared detection rod.

[0006] Further improved, the assembly screw rod includes a first screw rod and a second screw rod arranged oppositely. The first screw rod is in threaded connection with the right movable push plate, and the second screw rod is in threaded connection with the left movable push plate. A rotating rod head is arranged between the first screw rod and the second screw rod. The two ends of the rotating rod head respectively rotate and penetrate into the opposite sides of the first screw rod and the second screw rod. The first motor is in transmission connection with the first screw rod, and the second motor is in transmission connection with the second screw rod.

[0007] Further improved, push rods are movably connected to both the front and rear sides of the right movable push plate and the left movable push plate. The push rods are staggeredly distributed from the conveying rollers of the front conveying roller frame, and the lower side of the push rods is horizontally lower than the upper horizontal plane of the conveying rollers.

[0008] Further improved, a plurality of longitudinally distributed connection holes are provided on both the front and rear sides of the right movable push plate and the left movable push plate, and the push rods are locked to two corresponding connection holes by screws.

[0009] Further improved, the cutting mechanism is located at the rear side of the correction assembly. The cutting mechanism includes a lower knife table fixedly installed in the middle of the cutting machine frame and an upper knife plate movably arranged above the lower knife table. A plurality of first telescopic rods are vertically installed on the upper side of the cutting machine frame, and the telescopic ends of the first telescopic rods are connected to the top of the upper knife plate.

[0010] Further improved, two second telescopic rods are also installed on the cutting machine frame, and a rotating pressure roller is rotatably installed at the telescopic ends of the two second telescopic rods. The rotating pressure roller is located between the lower knife table and the correction assembly.

[0011] Compared with the prior art, the present utility model has the following advantages:

[0012] The structure of the present application is simple and ingenious. By combining the use of the correction assembly and the cutting mechanism, the positioning and conveying and cutting of the plate can be effectively carried out. The correction assembly uses the infrared detection rod to detect the position of the plate to see if it deviates from the conveying position, and then the left movable push plate and the right movable push plate can be separately controlled to move left or right according to the needs, so as to correct the position of the plate conveyed on the front conveying roller frame, and combine the rotating pressure roller of the cutting mechanism to roll the plate, so that the plate can be more stably cut and disconnected between the upper knife plate and the lower knife table, and the accuracy is good;

[0013] In order to drive the left movable push plate and the right movable push plate to move separately and accurately and stably, an assembled screw rod is provided. The assembled screw rod mainly uses the rotating rod head to rotationally insert the first screw rod and the second screw rod, so that the first screw rod and the second screw rod can play an overall supporting effect while being able to rotate separately. Thus, by driving the first screw rod and the second screw rod to rotate separately by the first motor and the second motor respectively according to the needs, the left movable push plate and the right movable push plate can be moved left or right respectively, which is more flexible in application and suitable for the alignment of plates with different widths, and has good applicability;

[0014] Push rods are arranged in the front and rear of the left movable push plate and the right movable push plate to push the plate. The advantage of this setting is that the push rods can stagger the infrared detection rod, and the push rods can be quickly maintained and replaced, and the height position of the push rods can also be adjusted, which is flexible and convenient to use.

Detailed implementation manners

[0022] In order to make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0023] Please refer to Figures 1-5, the present utility model provides a technical solution for a sheet cutting machine: including a cutting machine frame 1, a front conveying roller frame 3 provided on the front side of the cutting machine frame 1, and a rear conveyor belt 31 installed on the rear side of the cutting machine frame 1. It is characterized in that a cutting mechanism 2 is provided in the middle of the cutting machine frame 1, and a correction component 4 for pushing the sheet to move left and right is provided above the front conveying roller frame 3; the correction component 4 includes vertical plates 41 installed on the left and right sides of the front conveying roller frame 3. A right movable push plate 42 and a left movable push plate 43 are movably arranged between the two vertical plates 41. An assembly screw 44 and a guide rod 45 are installed between the two vertical plates 41, and both the assembly screw 44 and the guide rod 45 pass through the middle parts of the right movable push plate 42 and the left movable push plate 43. A first motor 46 and a second motor 47 for controlling the rotation of the assembly screw 44 are respectively installed on the outer sides of the two vertical plates 41. An infrared detection rod 5 is also installed between the two vertical plates 41. The infrared detection rod 5 is located below the right movable push plate 42 and the left movable push plate 43, and the push rod 421 is staggeredly distributed from the infrared detection rod 5. By driving the assembly screw 44 to rotate through the first motor 46 and the second motor 47, combined with the action of the guide rod 45, the lateral fine adjustment of the sheet is realized, ensuring the accurate position of the sheet during the conveying process. Among them, the push rod 421, as a connecting component, is staggeredly distributed from the infrared detection rod 5, and this structural space is reasonably distributed to ensure its movement coordination and stability; the infrared detection rod 5 real-time monitors the edge position of the sheet, compares and analyzes it with the preset parameters, and immediately feeds back to the control system. If the sheet is detected to be offset, the control system responds quickly, and adjusts the actions of the right movable push plate 42 and the left movable push plate 43 through the first motor 46 and the second motor 47, timely correcting the position of the sheet, avoiding the cutting error caused by the position deviation. This design greatly improves the continuity and efficiency of sheet conveying and cutting, eliminates the need for frequent manual intervention, reduces the number of production interruptions, reduces labor costs, and at the same time increases the production speed and production capacity

[0024] Among them, the assembly screw 44 includes a first screw 442 and a second screw 443 arranged oppositely. The first screw 442 is threadedly connected to the right movable push plate 42, and the second screw 443 is threadedly connected to the left movable push plate 43. Since the assembly screw 44 is refined and split into the first screw 442 and the second screw 443, and the two are respectively threadedly connected to the right movable push plate 42 and the left movable push plate 43, such a design allows the distance between the two movable push plates to be independently adjusted, thereby realizing more flexible and precise correction of the position of the plate; a rotating rod head 441 is provided between the first screw 442 and the second screw 443, and both ends of the rotating rod head 441 are rotatably inserted into the opposite sides of the first screw 442 and the second screw 443 respectively. The first motor 46 is drivingly connected to the first screw 442, and the second motor 47 is drivingly connected to the second screw 443. A rotating rod head 441 is added between the first screw 442 and the second screw 443, and both ends of it are respectively embedded in one side of the two screws to form an overall linkage structure. This not only ensures the stability of the synchronous movement of the two screws but also facilitates power transmission, enabling the first motor 46 and the second motor 47 to drive their respective corresponding screws more effectively. By establishing a driving connection between the first motor 46 and the second motor 47 and the first screw 442 and the second screw 443 respectively, independent drive of the double-screw system is achieved. Based on the real-time position feedback signal, the two motors can adjust the speed and direction as needed to ensure the smooth movement of the plate during correction, avoid deformation or damage of the plate caused by excessive unilateral force, and also enable a larger range of adjustment.

[0025] Both the front and rear sides of the right movable push plate 42 and the left movable push plate 43 are movably connected with push rods 421, and the lower horizontal plane of the push rod 421 is slightly lower than the upper horizontal plane of the conveying roller. The purpose of this design is to contact the plate through the single-point contact of the push rod 421, reduce the resistance of the plate during movement, and reduce frictional loss. The push rod 421 is staggeredly distributed from the conveying rollers of the front conveying roller frame 3 to avoid direct interference when the push rod 421 moves. Moreover, a plurality of longitudinally distributed connecting holes 422 are opened on both the front and rear sides of the right movable push plate 42 and the left movable push plate 43, and the push rod 421 is locked to the corresponding two connecting holes 422 by screws. Through the design of the connecting holes 422, the push rod 421 can be adjusted to ensure the best acting point. Facing plates of different thicknesses or widths, the design of the connecting holes 422 enables the equipment to be quickly adjusted, and the screw-locking method is convenient for quick disassembly, installation, and adjustment, providing convenience for daily maintenance and equipment upgrading.

[0026] Moreover, the cutting mechanism 2 is located at the rear side of the calibration assembly 4. The cutting mechanism 2 includes a lower knife table 22 fixedly installed in the middle of the cutting machine frame 1 and an upper knife plate 21 movably arranged above the lower knife table 22. On the upper side of the cutting machine frame 1, two first telescopic rods 23 are vertically installed, and the telescopic ends of the two first telescopic rods 23 are connected to the top of the upper knife plate 21. Through the telescopic movement of the first telescopic rods 23, the upper knife plate 21 can quickly cut down the plate on the lower knife table 22. The cutting machine frame 1 is also equipped with two second telescopic rods 6, and a rotating pressure roller 7 is rotatably installed at the telescopic ends of the two second telescopic rods 6. The rotating pressure roller 7 is located between the lower knife table 22 and the calibration assembly 4. After the calibration assembly 4 calibrates the position, the conveying of the plate is made more stable through the rolling of the rotating pressure roller 7.

[0027] During specific use, the plate is conveyed to the cutting machine frame 1, the cutting mechanism 2 and the rear conveyor belt 31 through the front conveyor roller frame 3. During this period, the infrared detection rod 5 of the calibration assembly 4 detects whether the position has shifted and feeds back to the control system. Then, according to the required position, the first motor 46 and the second motor 47 are respectively controlled to rotate. The rotation of the first motor 46 causes the left movable push plate 43 to move left and right through the threaded drive of the first screw rod 442, and the rotation of the second motor 47 causes the right movable push plate 42 to move left and right through the threaded drive of the second screw rod 443. The push rods 421 on the front and rear sides of the right movable push plate 42 and the left movable push plate 43 are used to push the middle plate to adjust its conveying position on the front conveyor roller frame 3, so as to achieve precise positioning and calibration. Then, the second telescopic rod 6 moves downward again, allowing the rotating pressure roller 7 to roll and press the plate tightly, further improving the stability of the plate conveying. Then, the first telescopic rod 23 moves downward to drive the upper knife plate 21 to quickly cut the plate on the lower knife table 22. The cut plate is conveyed to the outside by the rear conveyor belt 31. This has strong continuity in the cutting of the plate and high automation, which is beneficial to improving production efficiency.

[0028] It should be noted that for a plate cutting machine of the present utility model, its main improvement lies in the above structure.
