Description

Technical Field

[0001] This utility model relates to the field of coated paper processing technology, specifically to a coated paper processing conveying device with a correction function. Background Technology

[0002] Laminated paper is a specially treated type of paper, commonly used in packaging and moisture protection. Its manufacturing process involves coating the paper surface with a layer of plastic film, giving it excellent waterproof, oil-proof, and abrasion-resistant properties. Laminated paper is widely used in food packaging, pharmaceutical packaging, and other products requiring moisture protection. However, during the production of laminated paper, the base paper needs to be conveyed through multiple guide rollers. Due to the increased conveying distance, positional deviations are prone to occur. If these deviations are not corrected in time, the conveying efficiency will be affected, leading to problems in subsequent processing stages and ultimately reducing the product's functionality and appearance quality. Therefore, to ensure the production efficiency and finished product quality of laminated paper, using a base paper conveying correction mechanism to prevent base paper deviation is particularly important.

[0003] Patent CN217498151U discloses a paper guiding and correction mechanism for coated paper production. The mechanism includes a machine body with multiple mounting seats at both the front and rear ends. Guide rollers are mounted on the inner sides of both the front and rear mounting seats. Each guide roller has a stop plate above its front and rear ends, and each stop plate has an adjusting rod at its outer end. An adjusting disc is mounted on the outer end of each adjusting rod. A screw is mounted on the inner side of the two guide rollers, and a correction roller is mounted on the outer side of the screw. The mechanism is started by a rotating motor, which drives the screw to rotate via a coupling. This causes the screw to drive the correction roller to rotate. Simultaneously, depending on the forward and reverse rotation of the motor, the screw drives the correction roller to move back and forth via its internal thread. This allows the correction roller to adjust the position of the paper, improving the paper guiding efficiency. Multiple friction protrusions increase the friction between the paper and the correction roller, facilitating the back-and-forth movement of the paper by the correction roller, thereby achieving the purpose of adjusting the paper's position.

[0004] The aforementioned existing technology uses an adjusting disc to move an adjusting rod, which in turn moves a stop plate back and forth, adjusting the distance between the two stop plates. These stop plates limit the position of the raw paper, preventing it from shifting during transport. However, the fixed design of this guiding and correcting mechanism and the friction between the stop plates and the edge of the raw paper can still cause the paper to shift to one side during transport. This existing technology does not provide a real-time dynamic correction solution and cannot effectively monitor and adjust the raw paper in real time during transport. Based on these shortcomings, we propose a coated paper processing conveying device with a correction function, designed to detect and adjust the position of the raw paper in real time, improving the accuracy and efficiency of the conveying process, thereby ensuring the production quality of the coated paper. Utility Model Content

[0005] The purpose of this invention is to provide a coating paper processing and conveying device with a correction function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A coated paper processing conveying device with a correction function includes a base for supporting the overall structure of the device and maintaining stability. A conveying component is provided on the top of the base for conveying the base paper and adjusting the correction angle. The conveying component includes a rotating shaft, which is driven to rotate in both directions by a drive component to adjust the conveying direction. The rotating shaft is rotatably connected to the base via bearings. A U-shaped plate is provided on the top of the rotating shaft for fixing the conveying roller and providing swing support. A conveying roller is rotatably connected between the left and right sides of the inner wall of the U-shaped plate for directly contacting and conveying the base paper. A motor is provided on one side of the U-shaped plate for driving the conveying roller to rotate, and the motor provides rotational power to the conveying roller.

[0008] The bottom of the base is provided with a drive assembly for driving the rotating shaft to rotate in both directions. The drive assembly controls the deflection angle of the rotating shaft through rack and pinion transmission. The top of the base and the left and right ends near the rear side are provided with position adjustment components. The position adjustment components are used to adjust the lateral position of the photoelectric sensor to adapt to different paper widths. The position adjustment components are provided with photoelectric sensors for monitoring the edge position of the paper.

[0009] The photoelectric sensor is used to monitor the edge position deviation of the raw paper in real time and trigger the correction action. The motor, photoelectric sensor and electric cylinder are all connected to an external power supply and controller. The two position adjustment components adjust the position of the two photoelectric sensors respectively, so that the two photoelectric sensors can monitor the two sides of the raw paper. When the left photoelectric sensor detects that the raw paper has shifted to the left and blocked the light of the photoelectric sensor, the right end of the conveying roller of the conveying component rotates slightly backward to adjust the subsequent conveying path of the raw paper.

[0010] Preferably, the base has supports on both the left and right sides of its bottom, and the supports are used to support the base. The base also has arc-shaped guide plates on its top and near the left and right sides, which are used to guide the movement trajectory of the guide wheels and limit the swing range.

[0011] Preferably, the bottom of the U-shaped plate and near the four corners are provided with U-shaped blocks. The U-shaped blocks are used to install guide wheels and casters. The opening of the U-shaped blocks faces the adjacent arc-shaped guide plate. The upper and lower sides of the inner wall of the U-shaped blocks are rotatably connected to the guide wheels. The guide wheels roll along the concave surface of the arc-shaped guide plate to ensure the smooth swing of the conveying assembly.

[0012] Preferably, the bottom of the U-shaped solid block is rotatably connected to a caster wheel, which rolls on the top of the base and is used to assist the stable rotation of the conveying component.

[0013] Preferably, the drive assembly includes two fixed side plates arranged symmetrically to the left and right. The top of the fixed side plates is bolted to the bottom of the base. An electric cylinder is provided on the right side of the right fixed side plate. The electric cylinder pushes the rack to move laterally through a movable rod to drive the gear. The movable rod of the electric cylinder passes through the side of the fixed side plate and is fixedly connected to the rack. The rack meshes with the gear to transmit power to the rotating shaft. The bottom end of the rotating shaft is provided with a gear that meshes with the rack to transmit power. The gear converts the linear motion of the rack into the rotational motion of the rotating shaft.

[0014] Preferably, a guide rod is provided on the right side of the fixed side plate on the left, and a connecting groove for inserting the guide rod is provided on the left side of the rack. The guide rod is used to limit the movement direction of the rack and prevent it from deviating.

[0015] Preferably, the position adjustment component includes a frame plate for supporting a lead screw. The bottom of the frame plate is bolted to the top of the base. A lead screw is rotatably connected between the left and right sides of the inner wall of the frame plate. The lead screw rotates to move the support column laterally to adjust the position of the photoelectric sensor. The outer wall of the lead screw is threaded with a support column for fixing the photoelectric sensor and moving with the lead screw. One end of the lead screw passes through the inner wall of the frame plate and is fixedly connected to a knob for manually adjusting the rotation of the lead screw to achieve precise positioning. A scale is provided on the rear side of the frame plate to display the movement distance of the support column to assist in position calibration.

[0016] Preferably, the front and rear sides of the support column are respectively attached to the front and rear sides of the inner wall of the frame plate, and the photoelectric sensor is connected to the top of the support column by bolts.

[0017] Preferably, mounting seats are provided at the bottom of the front and rear sides of the frame plate and near the left and right ends. The mounting seats are connected to the top of the base by bolts, and the mounting seats fix the frame plate to the top of the base by bolts to enhance stability.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This coated paper processing conveyor with correction function uses photoelectric sensors to monitor the edge position of the raw paper in real time, and combined with the dynamic adjustment of the conveyor roller angle by the drive component, it can respond to the problem of raw paper deviation in an instant, avoid the cumulative error caused by the delay of the traditional fixed correction mechanism, and significantly improve the correction accuracy and efficiency.

[0020] 2. The coating paper processing conveyor with the correction function adopts a design with guide wheels rolling along the arc-shaped guide plate and universal wheels for auxiliary support, which limits the swing trajectory of the conveyor components, ensures that the correction action is smooth and reliable, and avoids secondary deviation problems caused by mechanical vibration or inertia.

The motor 33 provides rotational power to the conveying roller 32.

[0037] The bottom of the base 1 is provided with a drive assembly 2 for driving the rotating shaft 30 to rotate in both directions.

The motor 33, the photoelectric sensor 5 and the electric cylinder 21 are all connected to an external power supply and controller. The two position adjustment components 4 adjust the positions of the two photoelectric sensors 5 respectively, so that the two photoelectric sensors 5 can monitor the two sides of the raw paper respectively. When the left photoelectric sensor 5 detects the raw paper, that is, when the raw paper is offset to the left and blocks the light of the photoelectric sensor 5, the right end of the conveying roller 32 of the conveying assembly 3 rotates slightly backward to adjust the subsequent conveying path of the raw paper.

[0039] In this embodiment, brackets 10 are provided on both the left and right sides of the bottom of the base 1. The brackets 10 are used to support the base 1.

[0041] Furthermore, the bottom of the U-shaped fixed block 35 is rotatably connected to a caster wheel 36, which rolls on the top of the base 1. The caster wheel 36 is used to assist the transmission assembly 3 in rotating stably.

[0042] Furthermore, the drive assembly 2 includes two fixed side plates 20 arranged symmetrically on the left and right. The top of the fixed side plate 20 is bolted to the bottom of the base 1. An electric cylinder 21 is provided on the right side of the fixed side plate 20. The electric cylinder 21 pushes the rack 22 to move laterally through the movable rod to drive the gear 34. The movable rod of the electric cylinder 21 passes through the side of the fixed side plate 20 and is fixedly connected to the rack 22. The rack 22 meshes with the gear 34 to transmit power to the rotating shaft 30. The bottom end of the rotating shaft 30 is provided with a gear 34 that meshes with the rack 22 for transmission. The gear 34 converts the linear motion of the rack 22 into the rotational motion of the rotating shaft 30.

[0043] Furthermore, a guide rod 23 is provided on the right side of the fixed side plate 20 on the left, and a connecting groove 220 for the guide rod 23 to be inserted is provided on the left side of the rack 22. The guide rod 23 is used to limit the movement direction of the rack 22 and prevent it from deviating.

[0044] Furthermore, the position adjustment component 4 includes a frame plate 40, which supports the lead screw 41. The bottom of the frame plate 40 is bolted to the top of the base 1. The lead screw 41 is rotatably connected between the left and right sides of the inner wall of the frame plate 40. The lead screw 41 rotates to drive the support column 42 to move laterally to adjust the position of the photoelectric sensor 5. The support column 42 is threadedly connected to the outer wall of the lead screw 41. The support column 42 is used to fix the photoelectric sensor 5 and move with the lead screw 41. One end of the lead screw 41 passes through the inner wall of the frame plate 40 and is fixedly connected to a knob 43. The knob 43 is used to manually adjust the rotation of the lead screw 41 to achieve precise positioning. A scale 44 is provided on the rear side of the frame plate 40. The scale 44 is used to display the moving distance of the support column 42 to assist in position calibration.

[0045] Furthermore, the front and rear sides of the support column 42 are respectively attached to the front and rear sides of the inner wall of the frame plate 40, and the photoelectric sensor 5 is connected to the top of the support column 42 by bolts.

[0046] Furthermore, mounting seats 45 are provided at the bottom of the front and rear sides of the frame plate 40 and near the left and right ends. The mounting seats 45 are connected to the top of the base 1 by bolts. The mounting seats 45 fix the frame plate 40 to the top of the base 1 by bolts to enhance stability.

[0047] In this embodiment, the coated paper processing conveying equipment with correction function is used by first fixing the base 1 in position using the bracket 10, then placing the raw paper on the conveying roller 32 of the conveying assembly 3, rotating the lead screw 41 by the knob 43 of the position adjustment component 4, and moving the support column 42 laterally according to the reading of the scale 44 to adjust the monitoring position of the photoelectric sensors 5 on both sides to match the width of the raw paper, and starting the motor 33 to drive the conveying roller 32 to rotate to convey the raw paper; when the raw paper deviates during the conveying process, the photoelectric sensor 5 on the left or right detects the deviation. When the edge of the paper is detected to block light, the signal is fed back to the controller and triggers the electric cylinder 21 of the drive assembly 2 to move. The electric cylinder 21 pushes the rack 22 to move along the limiting direction of the guide rod 23, which drives the gear 34 and the rotating shaft 30 to deflect. This causes the U-shaped plate 31 to drive the right or left end of the conveyor roller 32 to make a slight adjustment of the angle. At the same time, the guide wheel 37 in the U-shaped block 35 rolls along the arc guide plate 11, and the universal wheel 36 provides auxiliary support on the top of the base 1, ensuring that the conveyor assembly 3 swings smoothly to correct the paper path, thereby realizing dynamic correction of the paper and continuous and efficient conveying.
