Description
Technical Field
[0001] This utility model relates to the field of cardboard box processing technology, and in particular to a cardboard box stamping device with a correction function. Background Technology
[0002] In the carton production process, the stamping process is a crucial step, directly affecting the forming quality and production efficiency of the carton. Traditional carton stamping equipment has certain limitations in terms of automation and intelligence, especially in position control during the carton conveying process. As the carton moves on the conveyor belt, its position may shift due to fluctuations in conveyor belt speed, inconsistencies in carton size, or interference from external factors, which directly affects subsequent stamping operations.
[0003] To address this issue, some cardboard box stamping devices with web guiding functions have emerged on the market. However, these devices still have shortcomings in terms of web guiding accuracy, stability, and reliability. Some devices use mechanical web guiding mechanisms, which have limited web guiding accuracy and response speed, making it difficult to meet the requirements of high-precision stamping.
[0004] Therefore, developing a cardboard box stamping device that is simple in structure, low in cost, has high correction accuracy, and is stable and reliable has become an urgent problem to be solved in the cardboard box manufacturing industry. Utility Model Content
[0005] This utility model was developed in this context, aiming to achieve efficient and accurate stamping of cartons through optimized design of the correction mechanism, feeding guide mechanism and stamping mechanism, thereby improving production efficiency and yield, while reducing production costs and meeting the actual needs of the carton manufacturing industry.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A carton stamping device with a correction function includes a processing box, wherein a stamping mechanism and a conveyor belt are provided inside the processing box, and a correction mechanism is provided at the feed inlet of the processing box. The correction mechanism includes two support frames fixedly connected to the right end of the processing box. A feeding base plate and a fixed frame are fixedly connected between the two support frames. An adjustment box is fixedly connected to the upper surface of the fixed frame. An adjustment motor is fixedly installed on the surface of the adjustment box. A bidirectional lead screw is rotatably connected to the inner wall of the adjustment box. Two moving blocks are threadedly connected to the surface of the bidirectional lead screw. The bottom end of the moving block extends to the bottom of the fixed frame and is fixedly connected to a moving plate. A color mark sensor is fixedly installed on the lower surface of the moving plate. The surface of the support frame is provided with a feeding guide mechanism, which is used to limit and guide the cardboard. The surface of the support frame is provided with a rectangular limiting hole. The feeding guide mechanism includes a limiting frame that is slidably disposed inside the rectangular limiting hole. The two limiting frames are symmetrically distributed in the feeding of the processing box.
[0007] In a preferred embodiment, the inner wall of the limiting frame is rotatably provided with two guide rollers, and a drive box is fixed on the upper surface of the limiting frame. A drive motor is fixed on the upper surface of the drive box, the rotation shaft of the drive motor extends into the interior of the drive box and is fixedly connected to a drive synchronous wheel, and a driven synchronous wheel is rotatably provided on the inner wall of the drive box.
[0008] In a preferred embodiment, a transmission belt is mounted on the surface of the driving synchronous pulley and the driven synchronous pulley, and the driving synchronous pulley and the driven synchronous pulley are connected by the transmission belt. A rotating shaft is fixedly provided at the bottom of both the driving synchronous pulley and the driven synchronous pulley, and the bottom ends of the two rotating shafts are fixedly connected to the top end of the guide roller.
[0009] In a preferred embodiment, an electric telescopic rod is fixedly installed on the inner side of the support frame, the telescopic end of the electric telescopic rod extends to the outer side of the support frame and is fixedly connected to a linkage plate, and the top of the linkage plate is fixedly connected to the bottom of the limiting frame.
[0010] In a preferred embodiment, the stamping mechanism includes two pneumatic telescopic rods fixed to the upper surface of the processing box. The telescopic ends of the pneumatic telescopic rods extend into the interior of the processing box and are fixedly connected to a movable plate. The surface of the movable plate has two limiting through holes. Limiting rods are slidably provided on the inner walls of the limiting through holes. Pressure frames are fixed to the bottom ends of the two limiting rods, and compression springs are sleeved on the surface of the limiting rods. The bottom end of the compression spring is fixedly connected to the upper surface of the pressure frame, and the top end of the compression spring is fixedly connected to the lower surface of the movable plate.
[0011] In a preferred embodiment, a stamping part is fixedly installed on the lower surface of the movable plate, and a limit baffle is fixedly connected to the surface of the pressure frame. The surface of the limit baffle is provided with a sliding through hole that matches the stamping part, and the stamping part is slidably connected to the inner wall of the sliding through hole.

[0013] As can be seen from the above, the cardboard box stamping device with correction function provided by this utility model has the following technical effects.
[0014] Firstly, this invention features a highly efficient correction function. Through a correction mechanism, color mark sensors precisely position the cartons entering the processing bin, ensuring they maintain the correct position on the conveyor belt. An adjustable motor drives a bidirectional lead screw, causing two moving blocks to adjust the position of the moving plate and color mark sensors, accommodating cartons of different widths and enhancing the device's versatility and flexibility.
[0015] Secondly, this invention features a stable feeding guide. The feeding guide mechanism uses a limiting frame and guide rollers to limit and guide the carton, effectively preventing it from shifting or tilting during transport, thus improving the accuracy of stamping and the yield rate. The drive motor drives two guide rollers to rotate synchronously via a transmission belt, reducing the frictional resistance between the carton and the guide rollers, allowing the carton to smoothly enter the stamping area.
[0016] Secondly, the stamping mechanism uses a pneumatic telescopic rod as its power source, which has advantages such as simple structure, rapid action, and easy control. The pressure frame is slidably connected to the movable plate through a limit rod and maintains a stable downward pressure under the action of a compression spring, ensuring that the stamping parts can accurately stamp the carton. The design of the limit baffle prevents the carton from moving during the stamping process, further improving the accuracy and stability of the stamping. 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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figures 1 to 5 The present invention relates to a carton stamping device with a correction function, which mainly includes a processing box 1, a stamping mechanism 2, a correction mechanism 3, a feeding guide mechanism 4, a rectangular limiting hole 5, and a conveyor belt 6.
[0025] The processing box 1 is the main part of the entire device, used to house and support components such as the stamping mechanism 2, the correction mechanism 3, the feeding guide mechanism 4, and the conveyor belt 6. The feeding port of the processing box 1 is equipped with the correction mechanism 3, which is used to correct the carton entering the processing box 1.
[0026] It is worth noting that the stamping mechanism 2 includes two pneumatic telescopic rods 201 fixed to the upper surface of the processing box 1. The telescopic ends of the pneumatic telescopic rods 201 extend into the interior of the processing box 1 and are fixedly connected to a movable plate 202. Two limiting through holes are formed on the surface of the movable plate 202, and limiting rods 203 are slidably disposed on the inner walls of the limiting through holes. A pressure frame 204 is fixed to the bottom end of the two limiting rods 203 for placing and fixing the cardboard box to be stamped.
[0027] It should be noted that a compression spring 205 is fitted onto the surface of the limiting rod 203. The bottom end of the compression spring 205 is fixedly connected to the upper surface of the pressure frame 204, and the top end is fixedly connected to the lower surface of the movable plate 202, providing stable downward pressure. A stamping component 206 is also fixedly installed on the lower surface of the movable plate 202 for stamping the carton. A limiting baffle 207 is fixedly connected to the surface of the pressure frame 204. The surface of the limiting baffle 207 has sliding through holes that match the stamping component 206, ensuring that the stamping component 206 can accurately stamp the carton.
[0028] It is worth noting that by setting up a correction mechanism 3, the correction mechanism 3 includes two support frames 301 fixedly connected to the right end of the processing box 1. A feed base plate 302 and a fixed frame 303 are fixedly connected between the two support frames 301. An adjustment box 304 is fixedly connected to the upper surface of the fixed frame 303, and an adjustment motor 305 is fixedly installed on the surface of the adjustment box 304. A bidirectional lead screw 306 is rotatably connected to the inner wall of the adjustment box 304, and two moving blocks 307 are threadedly connected to the surface of the bidirectional lead screw 306.
[0029] It should be noted that the bottom end of the movable block 307 extends to the bottom of the fixed frame 303 and is fixedly connected to the movable plate 308. A color mark sensor 309 is fixedly installed on the lower surface of the movable plate 308 for accurately positioning the carton entering the processing box 1. It should be noted that a black label sticker is pasted on the surface of the carton plate, and the color mark sensor 309 can be used to sense and position the black label sticker.
[0030] The rotating shaft of the adjusting motor 305 extends into the interior of the adjusting box 304 and is fixedly connected to the driving gear 310. The surface of the bidirectional lead screw 306 is fixedly connected to the driven gear 311. The driving gear 310 meshes with the driven gear 311. The rotation of the adjusting motor 305 drives the bidirectional lead screw 306 to rotate, thereby driving the moving block 307 and the moving plate 308 to adjust their positions.
[0031] It is worth noting that by setting up a feeding guide mechanism 4, which is set on the surface of the support frame 301, the cardboard is limited and guided to prevent the carton from shifting or tilting during the conveying process. The surface of the support frame 301 is provided with a rectangular limiting hole 5, and the feeding guide mechanism 4 includes a limiting frame 401 that is slidably set inside the rectangular limiting hole 5. The two limiting frames 401 are symmetrically distributed at the feeding end of the processing box 1.
[0032] It should be noted that two guide rollers 402 are rotatably mounted on the inner wall of the limiting frame 401 for guiding the carton. A drive box 403 is fixed to the upper surface of the limiting frame 401, and a drive motor 404 is fixed to the upper surface of the drive box 403. The rotation shaft of the drive motor 404 extends into the interior of the drive box 403 and is fixedly connected to a drive synchronous pulley 405. A driven synchronous pulley 406 is rotatably mounted on the inner wall of the drive box 403. A transmission belt 407 is mounted on the surfaces of the drive synchronous pulley 405 and the driven synchronous pulley 406, and the transmission is connected through the transmission belt 407.
[0033] It should be noted that both the driving synchronous wheel 405 and the driven synchronous wheel 406 have a fixed rotating shaft 408 at their bottom. The bottom ends of both rotating shafts 408 are fixedly connected to the top ends of the guide rollers 402. The rotation of the drive motor 404 drives the two guide rollers 402 to rotate synchronously. An electric telescopic rod 409 is fixedly installed on the inner side of the support frame 301. The telescopic end of the electric telescopic rod 409 extends to the outer side of the support frame 301 and is fixedly connected to a linkage plate 410. The top end of the linkage plate 410 is fixedly connected to the bottom of the limiting frame 401. The telescopic movement of the electric telescopic rod 409 causes the limiting frame 401 to slide within the rectangular limiting hole 5, which facilitates adjustment according to the size of the carton.
[0034] Working Principle: During operation, the carton to be stamped is placed on the conveyor belt 6, which transports it to the feed inlet of the processing box 1. As the carton passes the feeding guide mechanism 4, the limiting frame 401 and guide roller 402 limit and guide the carton, ensuring it smoothly enters the stamping area. Simultaneously, the color mark sensor 309 accurately positions the carton. If a positional deviation is detected, the adjusting motor 305 drives the bidirectional lead screw 306 to rotate, causing the moving block 307 and moving plate 308 to adjust their positions, aligning the color mark sensor 309 with the correct position of the carton, thus achieving the correction function. When the carton enters below the stamping mechanism 2, the pneumatic telescopic rod 201 extends, pushing the movable plate 202 and pressure frame 204 downwards to perform the stamping operation. After stamping, the pneumatic telescopic rod 201 retracts, the pressure frame 204 resets under the action of the compression spring 205, and the stamped part 206 exits from the carton. At this time, the conveyor belt 6 transports the stamped carton to the next process, while continuing to transport the next carton to be stamped into the processing box 1, and the stamping operation is carried out in a cycle.
[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
