Description

Technical Field

[0001] This utility model belongs to the technical field of papermaking equipment, and in particular relates to a direction adjustment device for paper strips on a belt. Background Technology

[0002] In the papermaking industry, paper feeding is a crucial part of the paper production process. When a paper sheet breaks during production, narrow strips (typically 25 centimeters wide) are usually used to pull it back into a complete sheet (a full sheet is generally 5 to 6 meters wide).

[0003] However, in actual production, when narrow paper strips are pulled on a conveyor belt, the belt is driven by a motor and rotates at high speed. Given the narrow width of the paper strips, this high-speed and relatively complex operating environment easily leads to directional instability. Specifically, the narrow paper strips are prone to lateral deviation on the conveyor belt, and in severe cases, they may even run off the belt. This prevents the paper feeding operation from being completed smoothly, negatively impacting the continuity and efficiency of the entire paper production process, increasing downtime and subsequent adjustment costs.

[0004] Currently, there is a lack of effective devices specifically designed for directional control during the traction of such narrow paper strips. Most methods rely on operators' experience to observe and adjust manually. This approach is not only inefficient but also makes it difficult to guarantee the accuracy of the adjustments, failing to fundamentally solve the problem of narrow paper strip deviation and severely hindering the automation and efficiency of paper production. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a direction adjustment device for paper strips on a conveyor belt. It features adjustable anti-deviation adjustment components on both sides of the conveyor belt, using compressed air to precisely control the direction of the narrow paper strip, preventing it from deviating. The device has a compact structure, can adapt to different papermaking conditions, ensures continuous and efficient paper feeding, and effectively improves work efficiency. It solves the problem of the lack of effective devices specifically designed for directional control of such narrow paper strips in the prior art. Most existing technologies rely on operators' experience for manual observation and adjustment, which is not only inefficient but also makes it difficult to guarantee the accuracy of the adjustment, failing to fundamentally solve the technical problem of narrow paper strip deviation.

[0006] This invention is implemented as follows: a direction adjustment device for paper strips on a conveyor belt includes a frame. Inside the frame is a conveyor belt for conveying paper sheets and narrow paper strips. Support plates are fixedly connected to the top of the frame on both sides of the conveyor belt. Anti-deviation adjustment components are slidably installed on the top of the support plates. These anti-deviation adjustment components spray compressed air onto the downward conveyor belt to prevent the narrow paper strips from shifting in the left-right direction. Each anti-deviation adjustment component includes a main air supply pipe, a flexible air supply hose fixedly connected to the middle of the main air supply pipe, and evenly distributed branch air supply pipes fixedly connected to the bottom of the main air supply pipe. The branch air supply pipes slidably pass through the support plates, and air nozzles are fixedly installed at the bottom of each branch air supply pipe.

[0007] In a preferred embodiment of this invention, both ends of the internal structure of the frame are respectively connected to a drive wheel and a driven wheel via bearings. The conveyor belt is connected between the drive wheel and the driven wheel. A motor is fixedly installed on the outer wall of the frame, and the output end of the motor is fixedly connected to the shaft of the drive wheel.

[0008] This setting facilitates the operation of the conveyor belt and ensures the smoothness of the conveyor belt's conveying operation.

[0009] In a preferred embodiment of this utility model, the support plate is arranged in an L-shape, and a mounting plate is fixedly connected to the bottom outer wall of the support plate. The mounting plate has threaded holes, and the mounting plate and the frame are connected by bolts.

[0010] With this setup, the L-shaped support plate can simultaneously support the top anti-deviation adjustment component and fix the bottom frame. The mounting plate, with its threaded holes and bolts, not only facilitates the quick installation and disassembly of the support plate, but also allows for flexible adjustment of the support plate's fixed position on the frame according to the conveyor belt, adapting to different paper production requirements and improving the versatility of the device.

[0011] As a preferred embodiment of this utility model, a vertical plate is fixedly connected to the top outer wall of the support plate, an adjusting screw is threaded through the vertical plate, an adjusting plate is fixedly connected to the top of the gas transmission main pipe, the end of the adjusting screw is connected to the adjusting plate through a bearing, and a receiving through hole for the gas transmission hose to pass through is provided at the bottom of the vertical plate.

[0012] With this setting, rotating the adjusting screw can push the adjusting plate to slide the main gas supply pipe along the support plate, thereby adjusting the lateral position of the gas supply branch pipe and the jet nozzle, achieving precise control of the direction of narrow paper strips with different degrees of deviation; the accommodating through hole can limit the placement of the gas supply hose to ensure the stability of the gas supply.

[0013] As a preferred embodiment of this invention, the end of the air delivery hose is fixedly connected to the air outlet of an external air compressor.

[0014] This design facilitates a continuous and stable supply of compressed air to the nozzle, and the flexible nature of the air delivery hose allows for the sliding adjustment of the main air delivery pipe, ensuring that the air supply is not affected by position adjustments and improving the reliability of the device operation.

[0015] As a preferred embodiment of this utility model, the top of the support plate is provided with evenly distributed adjustment channels, which correspond one-to-one with the gas supply branch pipe and are slidably connected, and the jet nozzle is perpendicular to the top of the conveyor belt.

[0016] This setting guides and limits the gas supply branch pipe, ensuring that it does not deviate when the main gas supply pipe drives the branch pipe to slide, and ensuring that the jet nozzle is always aligned with the edge area of ​​the conveyor belt. The design of the jet nozzle perpendicular to the conveyor belt allows compressed air to act perpendicularly on the belt surface, maximizing the use of the fluid pressure difference to attract the narrow paper strip, improving the efficiency and accuracy of directional adjustment, and avoiding the weakening of the directional control effect due to airflow direction deviation.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting adjustable anti-deviation adjustment components on both sides of the conveyor belt, the direction of the narrow paper strip is precisely controlled by compressed air to prevent it from deviating. The device has a compact structure, is easy to install and maintain, and can be adapted to different papermaking conditions. With the help of stable belt drive and precise air supply, the paper feeding process is guaranteed to be continuous and efficient, which improves the automation and efficiency of papermaking production and effectively improves work efficiency.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] refer to Figures 1 to 4 As shown in the figure, the present invention provides a direction adjustment device for paper strips on a conveyor belt, including a frame 1. The inside of the frame 1 is a conveyor belt 2 for conveying paper sheets and narrow paper strips. Support plates 3 are fixedly connected to the top of the frame 1 on both the left and right sides of the conveyor belt 2. Anti-deviation adjustment components are slidably installed on the top of the support plates 3. The anti-deviation adjustment components are used to spray compressed air onto the conveyor belt 2 below to prevent the narrow paper strips from deviating in the left and right directions. The anti-deviation adjustment components include an air supply main pipe 4. An air supply hose 5 is fixedly connected to the middle of the air supply main pipe 4. Evenly distributed air supply branch pipes 401 are fixedly connected to the bottom of the air supply main pipe 4. The air supply branch pipes 401 slide through the support plates 3. An air nozzle 402 is fixedly installed at the bottom of the air supply branch pipes 401.

[0023] Specifically, both ends of the frame 1 are connected to a drive wheel 201 and a driven wheel 202 respectively via bearings. The conveyor belt 2 is connected between the drive wheel 201 and the driven wheel 202. A motor 203 is fixedly installed on the outer wall of the frame 1. The output end of the motor 203 is fixedly connected to the shaft of the drive wheel 201.

[0024] The above scheme facilitates the operation of the conveyor belt 2 and ensures the smooth operation of the conveyor belt 2.

[0025] Specifically, the support plate 3 is arranged in an L-shape, and an mounting plate 301 is fixedly connected to the bottom outer wall of the support plate 3. The mounting plate 301 has a threaded hole 302, and the mounting plate 301 and the frame 1 are connected by bolts.

[0026] Using the above scheme, the L-shaped support plate 3 can simultaneously support the top anti-deviation adjustment component and fix the bottom frame 1; the connection method of the mounting plate 301 with the threaded hole 302 and bolts not only facilitates the quick installation and disassembly of the support plate 3, but also allows for flexible adjustment of the fixed position of the support plate 3 on the frame 1 according to the conveyor belt 2, adapting to the paper production needs of different specifications and improving the versatility of the device.

[0027] Specifically, a vertical plate 601 is fixedly connected to the top outer wall of the support plate 3, and an adjusting screw 6 is threaded through the vertical plate 601. An adjusting plate 403 is fixedly connected to the top of the gas transmission main pipe 4. The end of the adjusting screw 6 is connected to the adjusting plate 403 through a bearing. A receiving through hole 602 for the gas transmission hose 5 to pass through is provided at the lower part of the vertical plate 601.

[0028] Using the above scheme, rotating the adjusting screw 6 can push the adjusting plate 403 to drive the main gas supply pipe 4 to slide along the support plate 3, thereby adjusting the lateral position of the gas supply branch pipe 401 and the jet nozzle 402, so as to achieve precise control of the direction of narrow paper strips with different degrees of deviation; the accommodating through hole 602 can limit the placement of the gas supply hose 5 to ensure the stability of the gas source delivery.

[0029] Specifically, the end of the air delivery hose 5 is fixedly connected to the air outlet of an external air compressor.

[0030] The above solution facilitates the provision of a continuous and stable compressed air source for the jet nozzle 402. Furthermore, the flexible nature of the air delivery hose 5 allows for the sliding adjustment of the main air delivery pipe 4, ensuring that the air supply is not affected by position adjustments and improving the reliability of the device operation.

[0031] Specifically, the top of the support plate 3 is provided with evenly distributed adjustment channels 303, which correspond one-to-one with the air supply branch pipe 401 and are slidably connected, and the jet nozzle 402 is perpendicular to the top of the conveyor belt 2.

[0032] Using the above scheme, the regulating channel 303 guides and limits the gas supply branch pipe 401, ensuring that the gas supply main pipe 4 will not deviate when it drives the gas supply branch pipe 401 to slide, and ensuring that the jet nozzle 402 is always aligned with the edge area of ​​the conveyor belt 2. The design of the jet nozzle 402 being perpendicular to the conveyor belt 2 allows compressed air to act perpendicularly on the belt surface, maximizing the use of the fluid pressure difference to attract the narrow paper strip, improving the efficiency and accuracy of directional adjustment, and avoiding the weakening of the directional control effect due to the deviation of the airflow direction.

[0033] The working principle of this utility model: In use, the motor 203 is started to drive the conveyor belt 2 to transport the paper sheets and narrow paper strips. The narrow paper strips pull the paper sheets. At the same time, the nozzles are adjusted according to the width of the narrow paper strips and their position on the conveyor belt 2. That is, the adjusting screw 6 is rotated to push the main air supply pipe 4 and the branch air supply pipe 401 to slide along the support plate 3, and the position of the jet nozzle 402 is adjusted to fit the narrow paper strips. An external air compressor supplies air to the main air supply pipe 4 through the air supply hose 5. The compressed air is delivered to the jet nozzle 402 through the branch air supply pipe 401 and sprayed vertically onto the surface of the conveyor belt 2. The suction force generated by the air pressure difference is used to precisely control the movement of the narrow paper strips along the belt running direction, ultimately preventing the narrow paper strips from deviating and ensuring the smooth progress of the paper feeding operation.
