Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of impregnated paper processing, and particularly relates to a conveying operation device for roll-mounted impregnated paper. BACKGROUND

[0002] Impregnated paper is a kind of paper treated by impregnation. It is based on ordinary paper, and the paper is soaked in special glue to make the glue penetrate into the paper fibers, thereby enhancing the waterproofness, wear resistance and tensile strength of the paper. Impregnated paper is widely used in packaging, printing, construction, home furnishing and other fields.

[0003] The production of impregnated paper needs to perform two main steps of impregnation and drying after the paper is unfolded, and the final product is often cut into a specific length and stacked. Since the length of the paper roll raw material is limited, when a roll of paper is used up, the machine needs to be stopped for replacement, and the free end needs to be manually pulled to the tail of the production line again to start the next production. This replacement process is time-consuming and labor-intensive, and there is a lot of material waste. SUMMARY

[0004] In view of the above situation, in order to overcome the defects of the prior art, the application provides a technical solution capable of automatically connecting two paper rolls. The overlapping connection of the heads and tails of the two paper rolls is controlled by manual or automatic means, which avoids the efficiency loss caused by stopping the machine and greatly reduces the waste of materials. However, if the newly installed central shaft can rotate freely, the end of the raw material paper roll will deviate from the future abutting position under the vibration of the equipment. If the end of the raw material paper roll has a "warp", the overlapping area of the two raw material paper rolls is easy to separate and disconnect in the subsequent process.

[0005] In order to maintain the angle of the newly installed raw material paper roll, the application further provides a technical solution capable of pushing the friction plate to be unlocked by rotating the impeller in the chamber. This solution not only realizes the angle positioning of the pre-installed paper roll, but also provides stable tension to the paper through the rotation resistance of the shaft.

[0006] The technical solution adopted by the application is as follows: the application provides a conveying operation device for roll-mounted impregnated paper, which comprises a temporary connection assembly, a telescopic connecting shaft assembly, a rotation unlocking assembly, a longitudinal lifting assembly and a main frame. The longitudinal lifting assembly is fixedly connected to the two ends of the main frame, the rotation unlocking assembly is slidably arranged in the longitudinal lifting assembly, the telescopic connecting shaft assembly is rotatably arranged on the rotation unlocking assembly, and the temporary connection assembly is clamped between the two telescopic connecting shaft assemblies. The mechanism composed of the temporary connection assembly, the telescopic connecting shaft assembly and the rotation unlocking assembly has two groups in total, one group of the shafts has a fixed position, and the other group of the shafts can be controlled to rise and fall by the longitudinal lifting assembly.

[0007] The scheme connects the head and tail of two paper rolls by temporary bonding, thereby completing the switching of two paper rolls without stopping, avoiding the influence of paper roll replacement on production efficiency, and greatly reducing the waste of raw paper rolls due to only needing to cut off the overlapping area.

[0008] Further, the temporary connection assembly comprises a center roll, a raw paper roll, a nozzle support and a glue nozzle, the raw paper roll is wound on the center roll, the nozzle support is fixed on the longitudinal lifting assembly, and the glue nozzle is arranged on the nozzle support and faces the contact position of the two raw paper rolls when the two raw paper rolls abut against each other.

[0009] When the two raw paper rolls abut against each other, the glue nozzle sprays quick-drying glue, thereby temporarily connecting the head and tail of the two raw paper rolls, and after the raw paper roll is completely released, the two raw paper rolls are separated by retracting the telescopic rod, and the empty center roll is manually or automatically replaced.

[0010] Further, the two ends of the center roll are symmetrically provided with flange parts and polygonal shafts, the telescopic shaft assembly comprises a telescopic shaft, the telescopic shaft is provided with a polygonal hole and a first end plate, and the polygonal shafts are slidingly arranged in the polygonal hole.

[0011] The telescopic shaft and the polygonal shafts are connected by the telescopic telescopic shaft, so that the center roll can rotate synchronously with the external rotating shaft and the telescopic shaft.

[0012] As preferred, the telescopic shaft assembly further comprises an external rotating shaft, the telescopic shaft is further provided with a polygonal shaft, the external rotating shaft is provided with a polygonal hole and a second end plate, and the polygonal shaft is slidingly arranged in the polygonal hole.

[0013] As preferred, the telescopic shaft assembly further comprises a first spring and a second spring, the first spring is arranged between the first end plate and the second end plate, and the second spring is arranged between the end of the polygonal shaft and the polygonal hole.

[0014] Further, the rotation unlocking assembly comprises an impeller and a liquid storage cavity, the impeller is fixed on the external rotating shaft, the external rotating shaft is rotatably arranged in the liquid storage cavity, the inside of the liquid storage cavity is filled with liquid, and the outside of the liquid storage cavity is uniformly provided with guide rods.

[0015] The rotation of the external rotating shaft needs to overcome the resistance of the impeller in the liquid storage cavity, and the resistance is only related to the rotation speed of the external rotating shaft and is irrelevant to the release process of the raw paper roll, so that when the free end of the raw paper roll is pulled, the rotation resistance of the external rotating shaft can keep the paper tensioned.

[0016] Further, the liquid storage cavity is provided with a friction plate at one end abutting against the second end plate, when the release of the raw paper roll drives the central roll shaft to rotate, the impeller can slide the liquid storage cavity to the outside by the liquid.

[0017] When the rotation speed of the impeller is low or stops rotating, the liquid storage cavity abuts against the second end plate under the elastic force of the pressing spring, thereby locking the angle of the external shaft, so that the end of the installed raw paper roll is located at the future abutting position of the two raw paper rolls, avoiding the angle deviation of the central roll shaft caused by vibration during processing.

[0018] Further, the rotation unlocking assembly further comprises a shaft seat and a pressing spring, the shaft seat is provided with a guide hole and a center hole, the guide rod is slidingly fitted in the guide hole, the external shaft is rotatably arranged in the center hole, and the impeller is arranged between the second end plate and the shaft seat.

[0019] Further, the longitudinal lifting assembly comprises a side frame and a telescopic rod, the side frame is fixedly connected to the two ends of the main frame, the nozzle support is fixedly connected to the side frame, the side frame is provided with a side sliding groove and a fixing groove, one group of the shaft seats is clamped in the fixing groove, and the other group of the shaft seats is slidingly arranged in the side sliding groove.

[0020] The beneficial effects achieved by the above structure are as follows: (1) The scheme connects the heads and tails of the two paper rolls by temporary bonding, thereby completing the switching of the two paper rolls without stopping, avoiding the influence of paper roll replacement on production efficiency, and greatly reducing the waste of raw paper rolls since only the overlapping area needs to be cut off.

[0021] (2) When the two raw paper rolls abut against each other, the glue nozzle sprays quick-drying glue at the same time, temporarily connecting the heads and tails of the two raw paper rolls, and after one raw paper roll is completely released, the telescopic rod is retracted to separate the two raw paper rolls, and the empty central roll shaft is manually or automatically replaced.

[0022] (3) The telescopic shaft and the polygonal shaft one are connected through the telescopic shaft, so that the central roll shaft can rotate synchronously with the external shaft and the telescopic shaft.

[0023] (4) The rotation of the external shaft needs to overcome the resistance of the impeller in the liquid storage cavity, and this resistance is only related to the rotation speed of the external shaft and is irrelevant to the release process of the raw paper roll, so that when the free end of the raw paper roll is pulled, the rotation resistance of the external shaft can keep the paper tensioned.

[0024] (5) When the rotating speed of the impeller is low or stops rotating, the liquid storage cavity is tightly attached to the second end plate under the elastic force of the pressing spring, thereby locking the angle of the external rotating shaft, so that the end of the installed raw paper roll is located at the future abutting position of the two raw paper rolls, and the angle deviation of the central roll shaft caused by vibration in the processing process is avoided.

The telescopic connecting shaft assemblies 2 are rotatably arranged on the rotary unlocking assemblies 3. The temporary connection assemblies 1 are clamped between the two telescopic connecting shaft assemblies 2. The mechanism composed of the temporary connection assemblies 1, the telescopic connecting shaft assemblies 2 and the rotary unlocking assemblies 3 has two groups in total. One group of the mechanism has a fixed axis position, and the other group of the mechanism can be controlled to lift or lower by the longitudinal lifting assemblies 4.

[0031] The two ends of the two paper rolls are connected by the temporary bonding mode, so that the switching of the two paper rolls is completed without stopping the machine. The influence of the replacement of the paper rolls on the production efficiency is avoided. Since only the overlapping area needs to be cut off, the waste of the raw paper roll 12 is greatly reduced.

[0032] The temporary connection assembly 1 comprises a center roll 11, a raw paper roll 12, a nozzle support 13 and a glue spraying nozzle 14. The raw paper roll 12 is wound on the center roll 11. The nozzle support 13 is fixedly connected to the longitudinal lifting assembly 4. The glue spraying nozzle 14 is arranged on the nozzle support 13. When the two raw paper rolls 12 abut against each other, the glue spraying nozzle 14 faces the contact position of the two raw paper rolls 12.

[0033] When two raw material paper rolls 12 are in contact, the glue spraying nozzles 14 can spray quick-drying glue at the same time, so as to temporarily connect the two raw material paper rolls 12 at the head and tail, and after one raw material paper roll 12 is completely released, the two raw material paper rolls 12 are separated by the retraction of the telescopic shaft 42, and the empty central shaft 11 is manually or automatically replaced.

[0034] The flange part 111 and the polygonal shaft one 112 are symmetrically arranged at the two ends of the central shaft 11, the telescopic shaft assembly 2 comprises a telescopic shaft 22, the telescopic shaft 22 is provided with a polygonal hole one 221 and a first end plate 222, and the polygonal shaft one 112 is slidingly arranged in the polygonal hole one 221.

[0035] Through the telescopic function of the telescopic shaft 22, the telescopic shaft 22 and the polygonal shaft one 112 can be connected, so that the central shaft 11 can rotate synchronously with the external rotating shaft 21 and the telescopic shaft 22.

[0036] The telescopic shaft assembly 2 further comprises an external rotating shaft 21, the telescopic shaft 22 is further provided with a polygonal shaft two 223, the external rotating shaft 21 is provided with a polygonal hole two 211 and a second end plate 212, and the polygonal shaft two 223 is slidingly arranged in the polygonal hole two 211.

[0037] The telescopic shaft assembly 2 further comprises a first spring 23 and a second spring 24, the first spring 23 is arranged between the first end plate 222 and the second end plate 212, and the second spring 24 is arranged between the end of the polygonal shaft two 223 and the polygonal hole two 211.

[0038] The rotation unlocking assembly 3 comprises an impeller 31 and a liquid storage cavity 32, the impeller 31 is fixedly connected to the external rotating shaft 21, the external rotating shaft 21 is rotatably arranged in the liquid storage cavity 32, the inside of the liquid storage cavity 32 is filled with liquid, and guide rods 321 are uniformly arranged on the outside of the liquid storage cavity 32.

[0039] The rotation of the external rotating shaft 21 needs to overcome the resistance of the impeller 31 in the liquid storage cavity 32, and the resistance is only related to the rotation speed of the external rotating shaft 21 and is irrelevant to the release process of the raw material paper roll 12, so when the free end of the raw material paper roll 12 is pulled, the rotation resistance of the external rotating shaft 21 can keep the paper tensioned.

[0040] The end of the liquid storage cavity 32, which is in contact with the second end plate 212, is provided with a friction plate, when the release of the raw material paper roll 12 drives the rotation of the central shaft 11, the impeller 31 can push the liquid storage cavity 32 to slide outward through the liquid.

[0041] When the rotating speed of the impeller 31 is low or stops rotating, the liquid storage cavity 32 is tightly attached to the second end plate 212 under the elastic force of the pressing spring 34, thereby locking the angle of the external rotating shaft 21, so that the end of the installed raw paper roll 12 is located at the future abutting position of the two raw paper rolls 12, avoiding the angle deviation of the central reel 11 caused by vibration during processing.

[0042] The rotating unlocking assembly 3 further comprises a rotating shaft seat 33 and a pressing spring 34, the rotating shaft seat 33 is provided with a guide hole 331 and a central hole 332, the guide rod 321 is slidingly arranged in the guide hole 331, the external rotating shaft 21 is rotatably arranged in the central hole 332, and the impeller 31 is arranged between the second end plate 212 and the rotating shaft seat 33. Under the elastic force of the pressing spring 34, one end of the liquid storage cavity 32 is pressed against the second end plate 212.

[0043] The longitudinal lifting assembly 4 comprises a side frame 41 and a telescopic rod 42, the side frame 41 is fixedly connected to the two ends of the main frame 5, the nozzle support 13 is fixedly connected to the side frame 41, the side frame 41 is provided with a side sliding groove 411 and a fixing groove 412, one of the rotating shaft seats 33 is clamped in the fixing groove 412, and the other rotating shaft seat 33 is slidingly arranged in the side sliding groove 411. The telescopic rod 42 is fixedly connected to the top of the side sliding groove 411, and the push rod end of the telescopic rod 42 is arranged on the rotating shaft seat 33.

[0044] As shown in Figure 9 , the circular solid line represents the raw paper roll 12, the lower raw paper roll 12 is fixed in position, and the upper raw paper roll 12 can move up and down, the circular dotted line represents the position of the raw paper roll 12 when it is at the top, and the arrows represent the rotating direction of the two raw paper rolls 12 when they are released; When one raw paper roll 12 is about to be completely released, the two raw paper rolls 12 are close to and abut against each other, and the quick-drying glue is sprayed towards the overlapping part through the glue spraying nozzle 14, the glue overlaps and connects the two raw paper rolls 12, thereby driving the new raw paper roll 12 to rotate and release, until the last raw paper roll 12 is completely released, then the two raw paper rolls 12 are separated and the glue spraying nozzle 14 is closed.

[0045] As shown in Figure 10 , the dashed area on the right represents a schematic view of the raw paper roll 12 after being unwound, and the dipped paper after drying is cut into a sheet product of a certain length and stacked for storage.

[0046] In specific use, first, the user needs to complete the installation of the two central reels 11 and the raw paper rolls 12. During installation, only the telescopic shaft 22 needs to be temporarily retracted, and then the connection between the polygonal shaft 112 and the polygonal hole 221 can be completed. During normal operation, the telescopic shaft 22 is kept outwardly extended under the elastic force of the second spring 24 and the first spring 23, thereby avoiding the central reel 11 from falling off.

[0047] In the initial state, the telescopic rod 42 is in the retracted state, and the two raw paper rolls 12 are away from each other. At this time, the free end of one raw paper roll 12 is manually pulled out and passed through the rollers in the subsequent process. Before the cutting process, there is a set of driving rollers that drive the paper movement. Under the drive of this roller, the paper continues to move, thereby pulling the central shaft 11 to rotate; The paper released from the raw paper roll 12 will go through the processes of glue dipping, glue removal (extrusion to remove excess glue on the surface), drying, etc. After the drying and hardening are completed, it will be cut into a specific length and stacked for storage.

[0048] The end of the unused raw paper roll 12 is located closest to the other raw paper roll 12, and the liquid storage cavity 32 is pressed against the second end plate 212 under the elastic force of the compression spring 34. Due to the presence of the friction plate on the end face of the liquid storage cavity 32, even if there is vibration during the operation of the equipment, it will not cause the rotation of the central shaft 11.

[0049] When the raw paper roll 12 being used is released, it will rotate with the central shaft 11, and at the same time, the telescopic shaft 22 and the outer rotating shaft 21 will rotate. When the outer rotating shaft 21 rotates with the impeller 31, it can apply a thrust force to the end of the liquid storage cavity 32 through the liquid in the liquid storage cavity 32, thereby separating the liquid storage cavity 32 and the second end plate 212. After unlocking, the central shaft 11 can freely rotate under smaller resistance. At this time, the rotation of the central shaft 11 only needs to overcome the resistance of the impeller 31 in the liquid, which is much smaller than the friction force when the liquid storage cavity 32 and the second end plate 212 are in contact.

[0050] When the friction coefficient between the liquid storage cavity 32 and the second end plate 212 is greater than 1, the resistance of the liquid is less than the friction resistance. The greater the friction coefficient, the greater the difference between the two.

[0051] When one raw paper roll 12 is about to be completely released, the telescopic rod 42 is extended, and the glue nozzle 14 is opened at the same time. This process can be manually controlled or automatically controlled by sensing the number of rotations of the central shaft 11. When the telescopic rod 42 is extended, the two raw paper rolls 12 approach each other, and the raw paper roll 12 being moved will contact the end of the other raw paper roll 12. After being sprayed with quick-drying glue, the two raw paper rolls 12 will be pressed against each other, thereby completing the overlap. At this stage, the two raw paper rolls 12 will rotate together until the raw paper roll 12 is completely released.

[0052] Then, the telescopic rod 42 is retracted to separate the two raw paper rolls 12. During the continuous release of one raw paper roll 12, the other central shaft 11 and raw paper roll 12 can be replaced manually or automatically.

[0053] It is to be understood that the terminology used herein such as first and second, and the like, is only used to distinguish one entity or action from another entity or action, and does not necessarily require or imply any such actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.
