[0015] In summary, the present invention has the following main advantages:

[0016] First, this device can easily adapt to cartons of different sizes through a displacement mechanism. During operation, the carton is placed between the two clamping arms, and the third motor is started. The motor drives the lead screw to rotate in the rail frame. Because the threads at both ends of the lead screw turn in opposite directions, the slider can be driven to slide in the opposite direction in the rail frame, thereby driving the clamping arms to move. This allows the conveyor belt and guide wheel on the clamping arms to fit tightly against both sides of the carton. In this way, whether it is a large carton or a small box, this device can quickly and accurately clamp and position it, greatly improving its adaptability to various packaging scenarios and ensuring that cartons of different specifications can be properly handled.

[0017] Secondly, by setting up a displacement mechanism, after the carton is clamped, if lateral adjustment is required, the second motor is turned on. The second motor drives the gear to rotate, and through meshing with the rack, drives the movable block to slide in the guide rail, thereby pushing the clamping mechanism to move laterally, achieving precise adjustment of the carton's lateral position. If the front and rear position of the carton needs to be adjusted during processing, the first motor is started. The first motor drives the pulley to make the conveyor belt run. By controlling the forward and reverse rotation of the motor, the front and rear displacement of the carton between the conveyor belt and the guide wheel can be flexibly changed, meeting the needs of processing any position on the top of the carton, greatly improving the flexibility and accuracy of processing.

[0018] Third, by setting up a longitudinal movement mechanism, the processing problems of cartons of different heights can be effectively solved. When in use, pull the pull plate to move the movable plate forward, squeeze the limit spring, and pull out the limit pin. This allows for flexible adjustment of the up and down position of the sliding block inside the vertical rail, thereby adjusting the height of the clamping mechanism to adapt to cartons of various heights and improve the ease of use of the device. After the height adjustment is completed, release the pull plate, the limit spring returns to its original position, and the limit pin re-inserts into the limit hole to stabilize the slider inside the vertical rail, enhancing the stability of the device during use. This not only broadens the adaptability range of the device but also ensures the smooth and reliable processing of cartons. Attached Figure Description

[0026] Example

[0027] refer to Figures 1 to 6 A pre-fixable positioning fixture for paper box processing according to this embodiment includes a base plate 1, a displacement mechanism 2 fixedly installed on the rear side of the base plate 1, a longitudinal movement mechanism 3 fixedly connected to the top of the displacement mechanism 2, and a clamping mechanism 4 fixedly installed on the front side of the longitudinal movement mechanism 3.

[0028] The clamping mechanism 4 includes a rail frame 41, which is fixedly connected to the front of the longitudinal movement mechanism 3. A lead screw 42 is rotatably connected inside the rail frame 41, with opposite thread directions at both ends. A slider 43 is threaded to both ends of the lead screw 42, and an adjustment assembly 45 is fixedly connected to the front of the slider 43. A third motor 44 is fixedly connected to one end of the rail frame 41, and the output end of the third motor 44 is connected to one end of the lead screw 42. When this pre-fixed positioning fixture for cardboard box processing is in operation, the displacement mechanism 2 first functions on the rear side of the base plate 1, moving the entire fixture to a suitable working position. Then, the longitudinal movement mechanism... 3. The height of the clamping mechanism 4 on the front of the cardboard box can be adjusted according to the height of the cardboard box to accommodate cardboard boxes of different heights. When the cardboard box needs to be positioned, the third motor 44 at one end of the rail frame 41 is started. The third motor 44 outputs power to drive the lead screw 42 to rotate inside the rail frame 41. Since the threads at both ends of the lead screw 42 turn in opposite directions, the two sliders 43 connected to it will slide in opposite directions or back to back inside the rail frame 41. When the sliders 43 slide, they will drive the adjustment component 45 connected to their front to move. The adjustment component 45 then performs pre-fixing and positioning operations on the cardboard box to ensure that the position of the cardboard box is stable during processing.

[0029] refer to Figures 1-4The adjusting assembly 45 includes a clamping arm 451, which is fixedly connected to the front of the slider 43. A groove 452 is formed on the inner side of the clamping arm 451. Pulleys 453 are rotatably connected to both ends of the groove 452 on the inner side of one clamping arm 451. A conveyor belt 454 is connected to the outer surface of the pulleys 453. A first motor 455 is fixedly connected to the rear top of the clamping arm 451 on the side with the conveyor belt 454. The output end of the first motor 455 passes through the top of the clamping arm 451 and the top of the conveyor belt 454 and is fixedly connected. Guide wheels 456 are rotatably connected at equal intervals to the inner groove 452 of the other clamping arm 451 away from the end with the conveyor belt 454. Anti-slip rubber sleeves 457 are fixedly connected to the outer surface of the guide wheels 456. During use, when the lead screw 42 rotates and drives the slider 43 to move, the clamping arm 451 fixedly connected to the front of the slider 43 will move accordingly. When the two clamping arms 451 are in contact... When the cardboard box is placed close together and positioned in the middle, the first motor 455 on the rear top of the clamping arm 451 with the conveyor belt 454 is activated. The first motor 455 outputs power to drive the pulley 453 connected to its output end to rotate. Since the outer surface of the pulley 453 is connected to the conveyor belt 454, it drives the conveyor belt 454 to rotate. At the same time, the guide wheel 456, which is rotatably connected at equal intervals in the groove 452 on the inner side of the other clamping arm 451, has an anti-slip rubber sleeve 457 on its outer surface to increase the friction with the surface of the cardboard box. Together with the conveyor belt 454, the guide wheel 456 acts on the cardboard box. Through the rotation of the conveyor belt 454 and the assistance of the guide wheel 456, the cardboard box can be stably clamped and positioned. On the other hand, if the position of the cardboard box needs to be adjusted, the forward and reverse rotation of the first motor 455 can be controlled to make the conveyor belt 454 drive the cardboard box to move back and forth, so as to flexibly adjust the position of the cardboard box to meet different needs in the cardboard box processing process.

[0030] refer to Figures 1-3The displacement mechanism 2 includes a guide rail 21, which is fixedly connected to the back of the substrate 1. A movable block 22 is slidably connected inside the guide rail 21, and a mounting bracket 23 is fixedly mounted on the outside of the movable block 22. The top of the movable block 22 is connected to the bottom of the longitudinal movement mechanism 3. A drive assembly 24 is fixedly connected to the back of the movable block 22. The drive assembly 24 includes a second motor 241 and a rack 242. The rack 242 is fixedly connected to the lower end of the back of the guide rail 21, and the second motor 241 is fixedly connected to the middle of the back of the mounting bracket 23. The output end of the second motor 241 passes through the mounting bracket 23 and is fixedly connected to a gear 243. The gear 243 and the rack 242 are meshed together. During use, displacement is achieved by the displacement mechanism 2, wherein the guide rail 21 is fixed to the back of the substrate 1. The mounting bracket 23 provides a sliding track for the movable block 22. When the tooling position needs to be adjusted, the second motor 241 in the middle of the back of the mounting bracket 23 is started, and its output end drives the gear 243 to rotate. Since the gear 243 is meshed with the rack 242 fixed at the lower end of the back of the guide rail 21, the rotation of the gear 243 will push the movable block 22 to slide along the rack 242 inside the guide rail 21. The outer side of the movable block 22 is connected to the mounting bracket 23, and the top is connected to the longitudinal movement mechanism 3. Therefore, the sliding of the movable block 22 will drive the mounting bracket 23 and the longitudinal movement mechanism 3 and clamping mechanism 4 connected to it to move as a whole, thereby realizing the position adjustment of the tooling in the working area. This makes it convenient to move the tooling to the appropriate position according to the specific needs of cardboard box processing, thus providing convenience for cardboard box processing.

[0031] refer to Figures 1-3The longitudinal movement mechanism 3 includes a vertical rail 31, which is fixedly connected to the top of the movable block 22. A sliding block 32 is slidably connected inside the vertical rail 31. The front of the sliding block 32 is fixedly connected to the middle of the back of the rail frame 41. A limiting component 33 is provided on the top of the sliding block 32. The limiting component 33 includes limiting holes 331 and a frame 332. The limiting holes 331 are linearly arranged at equal intervals on the back of the vertical rail 31. The frame 332 is fixedly connected to the top of the slider 43. The internal structure of the frame 332 is fixedly connected to the top of the slider 43. A limit spring 333 is fixedly connected to the frame 332. A movable plate 334 is fixedly connected to the end of the limit spring 333. The movable plate 334 is slidably connected to the inside of the frame 332. A limit pin 335 is fixedly connected to the back of the movable plate 334. The end of the limit pin 335 passes through the frame 332 and is inserted into the inner side of the limit hole 331. A connecting shaft 336 is fixedly connected to the front of the movable plate 334. A pull plate 337 is fixedly connected to the end of the connecting shaft 336 through the movable plate 334. The vertical rail 31 is fixed to the movable block 2. 2. The top provides a track for the sliding block 32 to slide up and down. The front of the sliding block 32 is connected to the middle of the back of the rail frame 41, thereby driving the clamping mechanism 4 to lift and lower as a whole. When the height needs to be adjusted, the pull plate 337 is pulled. The pull plate 337 drives the movable plate 334 to move forward through the connecting shaft 336. At this time, the movable plate 334 presses the limiting spring 333 in the frame 332, causing the limiting spring 333 to retract. At the same time, the limiting pin 335 on the back of the movable plate 334 exits from the limiting hole 331 on the back of the vertical rail 31. Pull out the slide block 32 to release its restriction. The slide block 32 can slide freely up and down within the vertical rail 31 to adapt to paper boxes of different heights. After adjusting to the appropriate height, release the pull plate 337, and the limit spring 333 returns to its original state, pushing the movable plate 334 to move backward, so that the limit pin 335 is re-inserted into the corresponding limit hole 331, firmly fixing the slide block 32 and ensuring that the entire clamping mechanism 4 maintains a stable height during operation, meeting the positioning requirements of different heights during paper box processing.

[0032] Operating principle and advantages: This device, by setting up displacement mechanism 2, can effectively improve its adaptability to cartons of different sizes. In actual use, the carton is placed between the two clamping arms 451, and the third motor 44 is started. Its power output drives the lead screw 42 to rotate at high speed in the rail frame 41. Since the threads at both ends of the lead screw 42 rotate in opposite directions, the slider 43 is driven by the lead screw 42 in the rail frame 41 to achieve synchronous and opposite reciprocating sliding. The displacement of the slider 43 further drives the clamping arm 451 to move, so that the conveyor belt 454 and guide wheel 456 on the clamping arm 451 are precisely attached to both sides of the carton. In this way, regardless of the size of the carton, this device can quickly complete the clamping and positioning, which significantly enhances the practicality of the device in different packaging scenarios.

[0033] The displacement mechanism 2 is not only used for clamping and positioning the carton, but also plays a key role in adjusting the processing position of the carton. After the carton is clamped, if lateral position adjustment is required, the second motor 241 is started. The motor drives the gear 243 to rotate at high speed, forming a tight meshing transmission with the rack 242. Under this transmission mechanism, the movable block 22 slides smoothly in the guide rail 21, thereby pushing the clamping mechanism 4 to achieve lateral displacement. Through this operation, the lateral position of the carton can be precisely adjusted to meet processing requirements.

[0034] In addition, during the carton processing, it is often necessary to flexibly adjust the front and back positions of the carton. At this time, the first motor 455 is started, which drives the pulley 453 to rotate at high speed, thereby driving the conveyor belt 454 to rotate synchronously. The carton is located between the conveyor belt 454 and the guide wheel 456. By alternately controlling the forward and reverse rotation of the first motor 455, the front and back displacement of the carton on the conveyor belt 454 and the guide wheel 456 can be realized. This design allows the position of the carton to be flexibly and conveniently adjusted when processing any position on the top of the carton, which greatly improves the flexibility and accuracy of the processing.

[0035] The longitudinal movement mechanism 3 equipped in this device provides an efficient solution for processing cartons of different heights. In actual operation, pulling the pull plate 337 causes the connecting shaft 336 to drive the movable plate 334 forward. During this process, the limit spring 333 is squeezed and contracted, allowing the limit pin 335 on the movable plate 334 to be smoothly pulled out from the limit hole 331. At this time, the up and down position of the sliding block 32 in the vertical rail 31 can be easily adjusted, thereby flexibly changing the height of the entire clamping mechanism 4, ensuring that the device can adapt to cartons of various heights and effectively improving the ease of use of the device.

[0036] After the height adjustment is completed, release the pull plate 337. The limit spring 333 quickly returns to its original position, pushing the movable plate 334 back into place. This allows the limit pin 335 to re-insert into the limit hole 331. Through the tight engagement between the limit hole 331 and the limit pin 335, the slider 43 inside the vertical rail 31 is securely fixed, significantly enhancing the stability of the device during use. This design not only improves the adaptability of the device but also ensures that the device can maintain stable operation during carton processing, providing a strong guarantee for high-quality carton processing.
