Description

Technical Field

[0001] This invention relates to the field of paper processing technology, and in particular to an automated paper deep processing system. Background Technology

[0002] After paper is formed, it needs to undergo further processing such as coating, drying and rolling. To improve the efficiency of paper processing, most of the equipment or systems for further paper processing are designed to operate in an automated production mode.

[0003] To reduce the use of electric motors, the pressure roller assemblies in the coating and calendering units of paper deep processing systems are mostly designed to be synchronously driven by the same electric motor via chain transmission. To prevent the chain from loosening and failing during transmission, paper deep processing systems are mostly equipped with specially adapted tensioning mechanisms. These tensioning mechanisms are generally designed to be threaded for tightening and loosening. However, these tensioning mechanisms can usually only be driven to tighten the chain by manually turning the knob after the chain has loosened during operation. They cannot keep the chain tight when the gap between the two pressure roller assemblies or the roller torque between them is increased or decreased, so as to prevent the chain from falling off and failing during the adjustment process. This makes them impractical. Summary of the Invention

[0004] In view of this, the present invention provides an automated paper deep processing system to solve the problem that the tensioning mechanism cannot automatically tension and maintain the chain that may be loosened when the gap between the two pressure roller assemblies or the roller pressure torque between them is increased or decreased, so as to avoid the chain falling off and failing during the adjustment process, resulting in poor practicality.

[0005] The technical solution proposed in this invention is as follows: an automated paper deep processing system, specifically including a calendering module. The calendering module includes two symmetrically distributed vertical supports, hydraulic cylinders, and two calendering rollers arranged vertically and vertically. The vertical supports are welded together from T-shaped support members and U-shaped support frames. Hydraulic cylinders are fixedly suspended inside the U-shaped support frames. Calendering rollers are rotatably installed between the top portions of the two T-shaped support members. Bearing sleeves are fixedly suspended at the bottom ends of the telescopic rods of the two hydraulic cylinders. Calendering rollers are rotatably installed between the two bearing sleeves. The two calendering rollers press against each other in contact. Each calender roller is fixedly fitted with a roller shaft sprocket at the same end. The upper half of the U-shaped support frame is rotatably equipped with a guide sprocket. A U-shaped guide frame is welded to one side of the lower half of the U-shaped support frame. A sliding component is slidably installed inside the U-shaped guide frame. The sliding component is integrally formed by a cross-shaped slide bar and a hexagonal track shaft. A threaded drive shaft is rotatably connected to the first end of the sliding component. The threaded drive shaft is threadedly screwed into the short side plate of the U-shaped guide frame. A square slide sleeve is slidably fitted on the hexagonal track shaft in the form of a spring push. A tension sprocket is rotatably installed on the square slide sleeve.

[0006] Furthermore, a U-shaped retaining frame is welded to the top of the square sliding sleeve. A positioning rod is slidably installed inside the U-shaped retaining frame by means of a spring push. The bottom part of the positioning rod passes through the top wall of the square sliding sleeve and is inserted into the hexagonal track shaft.

[0007] Furthermore, a transmission chain is tensioned and installed on the tension sprocket, guide sprocket, and two roller sprockets.

[0008] Furthermore, two T-shaped sliders are symmetrically fixed to the outer circumference of the bearing sleeve, and two T-shaped grooves are symmetrically opened on the inner side of the two vertical side rods of the U-shaped support frame, with the T-shaped sliders slidingly engaging with the T-shaped grooves.

[0009] Furthermore, two symmetrically distributed connecting plates are integrally formed between the two ends of the hexagonal track shaft and the cross-shaped slide bar. The spring sleeve that pushes the square slide sleeve is mounted on the hexagonal track shaft and is compressed and clamped between the connecting plate near the U-shaped support frame and the square slide sleeve. A short axle is fixed to the outside of the square sleeve, and the tension sprocket is rotatably assembled with the short axle. Two strip grooves are symmetrically opened on the two long side walls of the U-shaped guide frame, and the cross-shaped slide bar slides in cooperation with the two strip grooves and the internal space of the U-shaped guide frame.

[0010] Furthermore, a limiting ring is fixedly fitted to the lower half of the positioning rod, and a spring that pushes the positioning rod is fitted onto the positioning rod and compressed and clamped between the limiting ring and the top side plate of the U-shaped retaining frame.

[0011] Furthermore, it also includes a coating module, which includes two symmetrically distributed vertical supports and hydraulic cylinders, as well as two coating rollers and trapezoidal paint tanks arranged vertically and vertically. The upper coating roller is rotatably mounted between two bearing sleeves on the coating module, and the lower coating roller is rotatably mounted between the tops of two T-shaped support members on the coating module. Two trapezoidal coating tanks are fixed between two vertical supports on the coating module and are positioned on the upper and lower sides of the two coating rollers. The top part of the upper coating roller protrudes through the bottom wall of the upper trapezoidal coating tank and is placed in the bottom space of the trapezoidal coating tank. The lower half of the lower coating roller is inserted into the lower trapezoidal coating tank, and the two coating rollers press against each other in contact.

[0012] Furthermore, it also includes a drying module, which includes two drying fans that are spaced apart vertically and symmetrically distributed, and two symmetrically arranged vertical frames. The drying fans are composed of a trapezoidal cloth hood and two electric heating fans that are symmetrically fixed on the closed side wall of the trapezoidal cloth hood. The paper to be further processed is sequentially guided through the extrusion gap between the two coating rollers, the passage space between the two drying fans, and the extrusion space between the two calendering rollers.

[0013] Furthermore, two longitudinal mounting plates are symmetrically welded to the outer side of the middle section of the two long side walls of the trapezoidal air cover. A photoelectric switch is fixed through the first end of the longitudinal mounting plate. The photoelectric switch is used to monitor whether the paper is stretched and broken.

[0014] Furthermore, motors are fixedly installed on the outer sides of the two T-shaped support members on the same side, and the two motors are respectively connected to the coating roller and calendering roller at the corresponding positions. An electrical control box is fixedly installed on a vertical frame. An audible and visual alarm is fixedly installed on the top of the electrical control box. The electrical control box contains an electrical control unit and an alarm control unit for controlling the start and stop of the motor and the audible and visual alarm. The alarm control unit is communicatively connected to a photoelectric switch and to the electrical control unit.

[0015] The automated paper deep processing system provided by this invention has the following beneficial effects: 1. Through the combined transmission of the drive chain, roller sprocket, guide sprocket and tension sprocket, two motors can drive two coating rollers and two calendering rollers to rotate synchronously in opposite directions. This eliminates the need to specially adapt drive motors for each coating roller and calendering roller, which helps to reduce the number of drive motors required by the processing system and reduce its manufacturing cost and power consumption.

[0016] 2. When the positioning rod is inserted into the hexagonal track shaft, the square sliding sleeve and the sliding component can be inserted and positioned together, so that the tensioning sprocket can be indirectly and fixedly connected to the sliding component and move synchronously with the sliding component. In this state, when the threaded drive shaft is rotated in the forward direction, it can push the sliding component and the tensioning sprocket away from the U-shaped support frame to slide, thereby tensioning the transmission chain that has become loose and reduced during operation, so as to restore the transmission performance of the transmission chain.

[0017] Third, in this invention, the sliding component, the threaded drive shaft, the square sliding sleeve, the tensioning sprocket, the positioning rod, and the spring on the hexagonal track shaft together constitute a tensioning mechanism for adjusting the tension of the transmission chain. This tensioning mechanism can not only adjust the tension of the slack transmission chain during normal use of the processing equipment to ensure the normal transmission performance of the transmission chain, but also automatically tension the transmission chain when adjusting the two coating rollers or the two calendering rollers to prevent the transmission chain from falling off and failing. It has the dual-purpose effect of one device and has good practicality. Attached Figure Description

The upper coating roller 6 is rotatably mounted between two bearing sleeves 1023 on the coating module, and the lower coating roller 6 is rotatably mounted between the tops of two T-shaped support members 101 on the coating module. The two trapezoidal coating troughs 5 are fixed at intervals between the two vertical supports 1 on the coating module and are arranged on the upper and lower sides of the two coating rollers 6. The top part of the upper coating roller 6 protrudes through the bottom wall of the upper trapezoidal coating trough 5 and is placed in the bottom space of the trapezoidal coating trough 5. The lower half of the lower coating roller 6 is inserted into the lower trapezoidal coating trough 5, and the two coating rollers 6 are pressed against each other.

[0030] Preferably, it also includes a drying module, which includes two drying fans 4 spaced apart vertically and symmetrically distributed, and two symmetrically arranged vertical frames 2. The drying fans 4 are composed of a trapezoidal cloth hood 401 and two electric heating fans 402 symmetrically fixed on the closed side wall of the trapezoidal cloth hood 401. The paper 8 to be further processed is sequentially guided through the extrusion gap between the two coating rollers 6, the passage space between the two drying fans 4, and the extrusion space between the two calendering rollers 11.

[0031] Preferably, two longitudinally mounted plates 403 are symmetrically welded to the outer side of the middle part of the two long side walls of the trapezoidal air cover 401.

[0032] Preferably, motors 10 are fixedly installed on the outer sides of the two T-shaped support members 101 located on the same side, and the two motors 10 are respectively driven by the coating roller 6 and the calendering roller 11 at the corresponding positions; an electrical control box 13 is fixedly installed on a vertical frame 2, and an audible and visual alarm 14 is fixedly installed on the top of the electrical control box 13. The electrical control box 13 is provided with an electrical control unit and an alarm control unit for controlling the start and stop of the motors 10 and the audible and visual alarm 14. The alarm control unit is communicatively connected to the photoelectric switch 404.

[0033] The working principle, specific details, implementation steps, functions and interrelationships of the features in the above embodiments, and the roles these features play in realizing this technical solution will be described and explained in detail below: Two motors 10 are used to drive the lower coating roller 6 and calendering roller 11 to rotate respectively. Through the combined transmission of the transmission chain 7, roller shaft sprocket 12, guide sprocket 1021 and tension sprocket 905, the two motors 10 can drive the two coating rollers 6 and the two calendering rollers 11 to rotate synchronously in opposite directions. This eliminates the need to specially adapt a drive motor for each coating roller 6 and calendering roller 11, which helps to reduce the number of drive motors required by the processing system and reduce its manufacturing cost and power consumption.

[0034] During processing, under the rotating roller conveyor of two coating rollers 6 and calendering roller 11, the paper 8 is first conveyed to the coating module. The two coating rollers 6 apply modified coatings to both the top and bottom surfaces of the paper to improve its smoothness and printability. After the coating process, the paper 8 is automatically conveyed to the drying module. Two corresponding drying fans 4 dry and soften the modified coatings on the paper. After drying, the paper 8 is automatically conveyed to the calendering module. The upper and lower calendering rollers 11 calender the paper 8 to improve its gloss and eliminate surface defects. Thus, under the continuous traction and conveyor of the coating rollers 6 and calendering roller 11, this processing system can automatically convey the raw paper (i.e., paper 8) to the coating module, drying module, and calendering module in sequence for deep processing of coating, drying and softening, and calendering.

[0035] The trapezoidal coating tank 5 contains modified coating. Since the top of the upper coating roller 6 is inserted through the bottom space of the upper trapezoidal coating tank 5, its top can continuously contact the modified coating in the bottom space of the trapezoidal coating tank 5 when it rotates with its body, and continuously adhere the modified coating to its outer periphery, thus performing roller coating on the upper surface of the paper 8. Since the lower half of the lower coating roller 6 is inserted into the lower trapezoidal coating tank 5, its lower half can continuously contact the modified coating in the trapezoidal coating tank 5 when it is driven to rotate, and continuously adhere the modified coating to its outer periphery, thus performing roller coating on the lower surface of the paper 8.

[0036] When the positioning rod 907 is inserted into the hexagonal track shaft 902, the square sliding sleeve 904 can be inserted into and positioned together with the sliding component 9, so that the tension sprocket 905 can be indirectly fixedly connected to the sliding component 9 and move synchronously with the sliding component 9. In this state, when the threaded drive shaft 903 is rotated in the forward direction, it can push the sliding component 9 and the tension sprocket 905 away from the U-shaped support frame 102 to slide, thereby tensioning the transmission chain 7 that has become loose and reduced during operation, so as to restore the transmission performance of the transmission chain 7.

[0037] During processing, it may be necessary to adjust the gap between the two coating rollers 6 and the calendering roller 11, as well as the roller pressure torque between them, according to different processing requirements. When the gap between the two coating rollers 6 or the two calendering rollers 11 needs to be increased to reduce the roller pressure torque between them, the upper coating roller 6 and calendering roller 11 slide upward away from the lower coating roller 6 and calendering roller 11. At this time, the transmission chain 7 will be stretched and tightened under the upward sliding drive of the upper coating roller 6 and calendering roller 11. It is necessary to slide the tension sprocket 905 toward the U-shaped support frame 102 to relax the transmission chain 7 and generate... The required slack allowance is provided when the drive chain 7 is stretched and tightened. When the distance between the two coating rollers 6 or the two calendering rollers 11 needs to be reduced to increase the roller pressure torque between them, the upper coating roller 6 and calendering roller 11 slide downwards closer to the lower coating roller 6 and calendering roller 11. At this time, the drive chain 7 loses the tension and support from the upper coating roller 6 and calendering roller 11 and is in a relaxed state. The tensioning sprocket 905 needs to be slid away from the U-shaped support frame 102 to stretch the drive chain 7 and keep it in a taut state to prevent the drive chain 7 from falling off the roller sprocket 12 and failing. Under the above conditions, When the positioning rod 907 is disengaged from the hexagonal track shaft 902, the square sliding sleeve 904 can be unlocked and released, restoring the pushing effect of the spring on the hexagonal track shaft 902 on the square sliding sleeve 904. This allows the square sliding sleeve 904 and its tensioning sprocket 905 to utilize the spring's reverse sliding motion to tension the transmission chain 7. Specifically, when adjusting and widening the gap between the two coating rollers 6 or the two calendering rollers 11 to reduce the roller pressure torque between them, the tensioned transmission chain 7 can be pulled to drive the tensioning sprocket 905 to slide towards the U-shaped support frame 102, thereby relieving the tension on the transmission chain 7 and creating space for the transmission chain 7 to be tensioned. The required loosening allowance during the stretching and tightening ensures that the upper coating roller 6 or calendering roller 11 can slide normally away from the lower coating roller 6 or calendering roller 11 to stretch and tighten the transmission chain 7, thereby reducing the roller pressure torque. During this process, when the square sliding sleeve 904 and the tension sprocket 905 are pulled and driven by the transmission chain 7 to slide towards the U-shaped support frame 102, they will compress the spring on the hexagonal track shaft 902. This spring can always apply its counter-force to the square sliding sleeve 904 and the tension sprocket 905, automatically pushing and tightening the transmission chain 7 to prevent the transmission chain 7 from falling off and failing during the above adjustment operation.When adjusting and reducing the gap between the two coating rollers 6 or the two calendering rollers 11 to increase the roller pressure torque between them, the transmission chain 7 becomes slack and loses the compressive holding force applied to the spring on the hexagonal track shaft 902 by the square sliding sleeve 904 and the tensioning sprocket 905. At this time, the spring can automatically push back to drive the square sliding sleeve 904 and the tensioning sprocket 905 away from the U-shaped support frame 102 to tension the slack transmission chain 7, so as to prevent the transmission chain 7 from falling off and failing during the above adjustment operation. After the positioning rod 907 is pulled away from the hexagonal track shaft 902 and the square sliding sleeve 904 is unlocked and released, the spring on the hexagonal track shaft 902 can automatically tension the transmission chain 7 during the adjustment of the two coating rollers 6 or the two calendering rollers 11, so as to prevent the transmission chain 7 from becoming slack and falling off and failing. The upper coating roller 6 and calendering roller 11 are driven to slide up and down by the hydraulic cylinder 3. In this invention, the sliding component 9, the threaded drive shaft 903, the square sliding sleeve 904, the tensioning sprocket 905, the positioning rod 907, and the spring on the hexagonal track shaft 902 together form a tensioning mechanism for adjusting the tension of the transmission chain 7. This tensioning mechanism can adjust the tension of the slack transmission chain 7 during normal use of the processing equipment to ensure the normal transmission performance of the transmission chain 7. It can also automatically tension the transmission chain 7 when adjusting the two coating rollers 6 or the two calendering rollers 11 to prevent the transmission chain 7 from falling off and failing. It has the dual-purpose effect of one device and has good practicality.

[0038] The principle of monitoring whether paper 8 is stretched and broken is as follows: When paper 8 is not stretched and broken, it lies flat under photoelectric switch 404 and can block the triggering of photoelectric switch 404. When photoelectric switch 404 is blocked from triggering, it sends a high-level signal and transmits the signal to the alarm control unit in real time. When the alarm control unit receives the signal, it determines that paper 8 is not stretched and broken, does not take any action, and does not output any control signal. When paper 8 is stretched and broken, it is broken and drooping, and falls off from under photoelectric switch 404, losing the blocking triggering effect on photoelectric switch 404. At this time, photoelectric switch 404 is in an untriggered state and sends a low-level signal. When the alarm control unit receives the signal, it determines that paper 8 has been stretched and broken, and issues a stop control command to the electrical control unit. After receiving the command, the electrical control unit switches the power supply of motor 10 and controls the entire processing system to automatically stop for protection, waiting for the staff to handle the paper breakage accident and restart. At the same time, when the alarm control unit receives the low-level signal, it activates the audible and visual alarm 14 to remind the staff that a paper breakage accident has occurred and to handle the accident in a timely manner to restore normal production as soon as possible.
