Description

Technical Field

[0001] The present invention relates to the technical field of corrugating rolls, and particularly to an adsorption type corrugating roll. Background Art

[0002] The main function of the adsorption type corrugating roll is to ensure that the corrugated paper does not slip during high-speed operation, thereby ensuring the forming quality of the cardboard; usually, the corrugated paper is firmly adsorbed on the roll surface by means of vacuum adsorption, avoiding the problems of cardboard slippage and poor forming that may be caused by the traditional mechanical clamping method. In related technologies, for example, the patent with the publication number CN210132825U in the prior art provides a vacuum adsorption corrugating roll. The corrugating roll includes a roll body, the roll body is provided with a coaxial inner cavity, the surface of the roll body is processed with air suction grooves, and each end of the roll body is fixedly connected with a shaft head, namely shaft head and shaft head, which can be collectively referred to as shaft head. The inside of the shaft head is provided with a non-through coaxial inner cavity (or no inner cavity), air suction holes are processed at the positions of the air suction grooves of the roll body, the air suction holes communicate with the inner cavity of the roll body, the end of the shaft head of the corrugating roll is provided with a through coaxial inner cavity, and the inner cavity communicates with the air suction holes of the air suction grooves of the roll body to form a vacuum channel. The vacuum air outlet or the air extraction port of the corrugating roll is arranged at the end of the shaft head.

[0003] Although the above-mentioned prior art solution can achieve the effect of adsorbing the cardboard by forming a vacuum channel inside the roll body through the air suction holes provided at the air suction grooves of the roll body, when the roll body continuously adsorbs the cardboard through the air suction holes, the other air suction holes that are not in contact with the cardboard are continuously inhaling air. During the air suction process, it is easy to adsorb impurities in the air (such as paper scraps, etc.) at the air suction holes, causing blockage.

Detailed implementation manners

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Please refer to Figures 1 - 12, the present invention provides a technical solution: an adsorption type corrugating roll, comprising: a corrugating roll barrel 1, which is driven to rotate by an external force and adsorbs corrugated paper. A roll core 2 is rotatably arranged inside the corrugating roll barrel 1. An air inlet pipe 3 is arranged at one end of the corrugating roll barrel 1 for supplying gas to the blowing assembly 211. A negative pressure pipe 4 is arranged at the end of the corrugating roll barrel 1 far from the air inlet pipe 3, and the negative pressure pipe 4 is communicated with the adsorption port 22. Wherein, a sealing gasket is arranged on the outer side of the roll core 2, and an anti-blowing port 21 and an adsorption port 22 are arranged inside the roll core 2. A blowing assembly 211 is hermetically and fixedly arranged inside the anti-blowing port 21. The blowing assembly 211 is located between the anti-blowing port 21 and the adsorption port 22 for isolating the anti-blowing port 21 and the adsorption port 22.

[0022] In the working state, the corrugating roll barrel 1 rotates relative to the roll core 2. Among them, the area corresponding to the adsorption port 22 adsorbs the corrugated paper, and the area corresponding to the anti-blowing port 21 can blow off the large impurities adsorbed on the outer side of the corrugating roll barrel 1 in real time, ensuring the effective adsorption of the corrugated paper by the adsorption port 22 in the subsequent working process.

[0023] The blowing assembly 211 includes a sealing cylinder 2111, which is detachably arranged inside the roll core 2 and fixedly arranged outside the air inlet pipe 3. Guide blocks 2113 are arranged on both sides of the top of the sealing cylinder 2111; the guide blocks 2113 are used to guide the gas blown out by the blowing assembly 211 to the inner side wall of the corrugating roll barrel 1.

[0024] A first air port 2112 is arranged on one side of the sealing cylinder 2111 close to the anti-blowing port 21. A second air port 31 is arranged on the air inlet pipe 3 corresponding to the first air port 2112. The first air port 2112 and the corresponding second air port 31 are communicated and both are arranged towards the anti-blowing port 21.

[0025] A rotating port 221 is arranged outside the adsorption port 22, and an adjusting assembly 5 is arranged inside the rotating port 221. The adjusting assembly 5 is used to adjust the adsorption area of the adsorption port 22.

[0026] A fixing frame 23 is fixedly arranged on the outer side of the roll core 2. The adjusting assembly 5 includes a first adjusting member 51, the first adjusting member 51 is a worm, the first adjusting member 51 is rotatably arranged inside the fixing frame 23, a second adjusting member 52 is meshed on the outer side of the first adjusting member 51, the second adjusting member 52 is a worm wheel, a connecting pipe 53 is fixedly arranged inside the second adjusting member 52, a transmission assembly 54 is arranged on the outer side of the connecting pipe 53, and rotating plates 55 are arranged on the outer sides of the transmission assembly 54 and the connecting pipe 53. The rotating plates 55 are rotatably arranged on the outer side of the fixing frame 23.

[0027] Wherein, a handle for easy gripping is arranged on the part of the first adjusting member 51 located outside the fixing frame 23.

[0028] The transmission assembly 54 includes a first transmission member 541 which is a bevel gear ring. The first transmission member 541 is fixedly arranged on the outer side of the connecting pipe 53. A second transmission member 542 which is a bevel gear ring is meshed on the outer side of the first transmission member 541. A third transmission member 543 which is a bevel gear ring is meshed on the side of the second transmission member 542 away from the first transmission member 541. The outer side of the connecting pipe 53 is rotatably arranged with the inner side of the third transmission member 543. A side of the third transmission member 543 is fixedly provided with an opening pipe 544, and the outer side of the opening pipe 544 is fixedly arranged with a side of the corresponding rotating plate 55.

[0029] That is, in the above technical solution, one rotating plate 55 is connected to one side of the connecting pipe 55, and the other rotating plate 55 is connected to one side of the opening pipe 544. The two rotating plates 55 are connected by the transmission assembly 54, so that when one of the rotating plates 55 is rotated, the other rotating plate 55 can rotate accordingly, and then the size of the adsorption area formed between the two rotating plates 55 changes.

[0030] An airbag 551 is arranged on the outer side of the rotating plate 55. A sealing plate 552 is arranged on the side of the airbag 551 close to the corrugated roller 1. An air charging pipe 553 is jointly arranged on the inner sides of the two airbags 551. The air charging pipe 553 is arranged inside the negative pressure pipe 4 and is used to connect an external air supply device.

[0031] In the above technical solution, neither the roller core 2 nor the flow guiding block 2113 contacts the inner wall of the corrugated roller 1. In the working state, the airbag 551 is in a filled state and is used to support the sealing plate 552, so that the sealing plate 552 abuts against the inner wall of the corrugated roller 1, separating the back blowing port 21 from the adsorption port 22. After working for a period of time, a large amount of dust is adsorbed on one side of the airbag 551. The air charging pipe 553 is used to reciprocally pump air into and out of the airbag 551, so that the airbag 551 shakes off the adsorbed dust.

[0032] Adsorption holes 11 are formed on the outer side of the corrugated roller 1 for adsorbing corrugated paper.

[0033] Rotating shafts 12 are fixedly arranged on both sides of the corrugated roller 1. The rotating shafts 12 are rotatably arranged inside the bearing bracket 6. One of the rotating shafts 12 is driven by an external force to rotate for driving the corrugated roller 1 to rotate. The air inlet pipe 3 is fixedly arranged on the outer side of the bearing bracket 6 through a mounting plate.

[0034] The air inlet pipe 3 is rotatably arranged inside the bearing bracket 6. A fixing bolt 61 is threadedly arranged on the side of the bearing bracket 6 close to the air inlet pipe 3 for fixing the air inlet pipe 3.

[0035] Based on the foregoing explanation, when a large amount of dust adheres to one side of the airbag 551 after working for a period of time, the dust needs to be shaken off. At this time, the fixing bolt 61 can be removed to fix the air inlet pipe 3, so that the roller core 2 and the air inlet pipe 3 rotate relative to the corrugated roller 1, making the side of the two airbags 551 that adsorbs dust face downward. At this time, the airbag 551 is reciprocally sucked and inflated through the air charging pipe 553, so that the airbag 551 shakes off the dust, and the shaken-off dust adheres to the inner wall of the corrugated roller 1; Subsequently, the gas in the airbag 551 is pumped out, and the contact between the sealing plate 552 and the inner wall of the corrugated roller 1 is released. The roller core 2 and the air inlet pipe 3 are rotated again, so that the blowing component 211 is aligned with the inner wall of the corrugated roller 1 where the shaken-off dust adheres. At this time, by blowing air through the blowing component 211, the dust here can be blown out from the adsorption hole 11. During the blowing process, the corrugated roller 1 can be reciprocally swung within a small range by an external force, so as to blow out the dust from the adsorption hole 11.

[0036] In the foregoing process, by pumping out the gas in the airbag 551 to release the contact between the sealing plate 552 and the inner wall of the corrugated roller 1, it is possible to avoid the scraping of the shaken-off dust by the sealing plate 552 during the rotation of the roller core 2 and the air inlet pipe 3 relative to the corrugated roller 1, which is convenient for the subsequent treatment of the dust by the blowing component 211.

[0037] Principle and advantages of the adsorption type corrugated roller: First, before use, the roller core 2 is installed inside the corrugated roller 1, and then the air inlet pipe 3 is installed outside the bearing bracket 6 through the mounting plate on one side, so that the air inlet pipe 3 is fixedly arranged inside the roller core 2, and the sealing cylinder 2111 outside the air inlet pipe 3 isolates the back blowing port 21 and the adsorption port 22, and the first air port 2112 is arranged on the side close to the back blowing port 21; When adsorbing the corrugated paper, the external negative pressure device is connected through the negative pressure pipe 4, and the inner side of the corrugated roller 1 is sucked through the included angle part between the two rotating plates 55. The corrugated paper is adsorbed through the adsorption holes 11 on the corrugated roller 1. The rotating shaft 12 on one side is driven to rotate by an external force, thereby driving the corrugated roller 1 to rotate, so that the corrugated roller 1 can drive the corrugated paper to rotate, which is convenient for subsequent forming operations. Among them, the airbag 551 always maintains an inflated state, so that the sealing plate 552 is tightly attached to the corrugated roller 1 to seal the space between the two rotating plates 55, so that the corrugated roller 1 can better perform the adsorption work; When adsorbing corrugated paper, larger impurities will be adsorbed on the outer side of the adsorption holes 11, and smaller impurities may be adsorbed from the adsorption holes 11 to the inner side of the corrugated roller 1 and adhere to the outer side of the airbag 551. When cleaning the impurities on the outer side, an external blowing device is connected through the air inlet pipe 3, and the air flow blows out through the second air port 31 and the first air port 2112 to blow the corresponding position on the inner side of the corrugated roller 1, so that the corrugated roller 1 rotates under the drive of an external force, and the impurities on the outer side of the adsorption holes 11 can be blown away. When cleaning smaller impurities, the airbag 551 is repeatedly evacuated and inflated through the air charging pipe 553, so that the airbag 551 repeatedly contracts and expands, and the impurities on the airbag 551 are shaken off. Subsequently, the airbag 551 is kept in a state of air extraction. By removing the fixing bolt 61 to fix the air inlet pipe 3, the air inlet pipe 3 is rotated by an external force, driving the sealing cylinder 2111 to rotate, thereby driving the roller core 2 to rotate inside the corrugated roller 1, so that the reverse blowing port 21 rotates to the side to be cleaned. After fixing the air inlet pipe 3 through the fixing bolt 61, blowing is carried out through the first air port 2112, and the corrugated roller 1 is driven to swing left and right by an external force to blow and clean the impurities, completing the cleaning process of the impurities on the inner and outer sides of the corrugated roller 1; When it is necessary to adjust the adsorption area of the adsorption port 22, the first adjusting member 51 is rotated through the handle on the outer side of the first adjusting member 51. The first adjusting member 51 drives the second adjusting member 52 and one of the rotating plates 55 to rotate. At the same time, the connecting pipe 53 drives the opening pipe 544 and the other rotating plate 55 to rotate through the transmission assembly 54, so that the included angle between the two rotating plates 55 changes, that is, the adsorption area of the adsorption port 22 is adjusted.

[0038] By removing the fixing bolt 61 to fix the air inlet pipe 3, the air inlet pipe 3 can be rotated by an external force, thereby driving the roller core 2 to rotate, adjusting the relative positions of the reverse blowing port 21 and the adsorption port 22 with respect to the corrugated roller 1, so that the direction of the corrugated roller 1 adsorbing the corrugated paper can be changed, increasing the practicability of the equipment; Its advantage is that an external blowing device is connected through the air inlet pipe 3, and the air flow blows out through the second air port 31 and the first air port 2112 to blow the corresponding position on the inner side of the corrugated roller 1, so that the corrugated roller 1 rotates under the drive of an external force, and the impurities on the outer side of the adsorption holes 11 can be blown away, effectively solving the problem in the prior art that it is not convenient to clean the suction holes, resulting in a gradual decrease in the adsorption capacity of the roller body.

[0039] In the adsorption type corrugated roller of the present application, the airbag 551 is repeatedly evacuated and inflated through the air charging pipe 553, so that the airbag 551 repeatedly contracts and expands, and the impurities on the airbag 551 are shaken off, and then blowing is carried out through the first air port 2112 to blow and clean the impurities.

[0040] Its advantage is that it can shake off and clean the impurities inhaled into the inner side of the corrugating roller 1 and attached to the outer side of the airbag 551, and can blow and clean the impurities through the blowing of the first air port 2112, increasing the effect of the equipment cleaning the impurities on the inner side of the corrugating roller 1.

[0041] It should be noted that the above method of adjusting the orientations of the reverse blowing port 21 and the adsorption port 22 has the following advantages: Advantage one: By driving the intake pipe 3 to rotate by an external force, the roller core 2 can be driven to rotate, thereby driving the reverse blowing port 21 to rotate to a suitable position, facilitating the blowing and cleaning of the impurities shaken off by the airbag 551, and increasing the effect of the equipment cleaning the impurities on the inner side of the corrugating roller 1.

[0042] Advantage two: By driving the intake pipe 3 to rotate by an external force, the roller core 2 can be driven to rotate, causing the adsorption port 22 to rotate to a suitable position, thereby changing the relative position between the adsorption port 22 and the corrugating roller 1, and further changing the adsorption position of the corrugating roller 1 on the corrugated paper.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
