Description

Technical Field

[0001] The invention relates to the technical field of calenders, in particular to a calender for wave absorbing materials. Background Art

[0002] Absorbing materials refer to a type of material that can absorb or significantly reduce the electromagnetic wave energy received on its surface, thereby reducing the interference of electromagnetic waves. Since the performance of absorbing materials is closely related to their thickness and shape, the precise control of the calender can ensure that the absorbing materials meet the required thickness and shape requirements during the processing, thereby ensuring the stability and consistency of their absorbing performance. Therefore, calenders are often used for processing absorbing materials.

[0003] As in the prior art, the patent with the patent authorization announcement number CN220313961U discloses a three-roll calender, including a frame, wherein the frames have two and are arranged in parallel, a rubber coating roller is arranged between the frames, and bearing seats are arranged at both ends of the rubber coating roller, one end of the bearing seat is connected to the frame, and the rubber coating roller is rotatably connected to the bearing seats at both ends through bearings, a second pressing roller is arranged at the top of one side of the rubber coating roller, a first U-shaped frame is arranged outside the second pressing roller, and the second pressing roller is rotatably connected to both sides of the inner wall of the first U-shaped frame through bearings, a first support rod is arranged at the top of one side of the second pressing roller, and the first support rod is connected to the frames at both ends, and a push-pull oil cylinder is fixedly installed on the top of the first support rod. When the three-roll calender is in use, the rubber material can be pressed into shape, and the thickness of the produced film is more uniform, and the structure is reasonable and the operation is convenient.

[0004] Although the three-roll calender in the above patent produces a more uniform film thickness, it still has certain defects. The roller bearing is a key component in the three-roll calender. Lubricating oil is essential to ensure the normal operation of the bearing and extend its service life. Therefore, the lubricating oil of the roller bearing needs to be replaced regularly to ensure its cleanliness and lubrication performance. When the lubricating oil of the bearing is replaced, the bearing needs to be removed first, and the bearing and its related parts need to be cleaned before new lubricating oil can be injected. Finally, the bearing needs to be installed back to its original position. During the replacement of the lubricating oil, the entire equipment cannot work, thereby reducing the production efficiency of the three-roll calender. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a calender for absorbing materials to solve the problems raised in the background art, shorten the downtime of the calender during lubricant oil replacement, and improve the production efficiency of the calender.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When replacing the lubricating oil of the bearing of the calender for this kind of absorbing material, it is only necessary to remove the bolts and push the turntable away from the roller through the first cylinder to disengage the plug block from the connecting block, then rotate the turntable to align another set of plug blocks with the connecting block, then pull the turntable back through the first cylinder again to insert new plug blocks into the connecting block, and apply lubricating oil to the bearings of these new plug blocks, while the bearings to be cleaned of the lubricating oil will enter the cleaning shell for cleaning, so that the replacement of the lubricating oil can be completed, reducing the downtime of the calender main body and improving production efficiency.

[0015] 2.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] See also Figures 1 to 12 A calender for absorbing materials, comprising a calender body 1 and a roller 3 installed on the calender body 1, two symmetrically arranged support seats 2 are fixedly connected to the rear side of the top of the calender body 1, a first cylinder 13 is fixedly connected to the side of the top of the support seat 2 close to the roller 3, a cleaning shell 5 is fixedly connected to the output end of the first cylinder 13, a rotating shaft 6 is fixedly connected to the middle position of the cleaning shell 5 close to the roller 3, a turntable 7 is sleeved on the outer side of the rotating shaft 6, and two groups of symmetrically arranged bearings are connected to the turntable 7, a plurality of nozzles 24 matching the bearings are fixedly connected to the side of the cleaning shell 5 close to the first cylinder 13, a drainage pipe 17 is fixedly connected to the lower end of the cleaning shell 5 away from the roller 3, a connecting shaft 14 is connected to the middle position of the bearing, and the connecting shaft 14 is connected to the roller 3, and a power component is connected to one end of the top of the calender body 1.

[0032] In the calender for wave-absorbing materials of the present invention, when the lubricating grease in the bearing deteriorates and needs to be replaced, the roller 3 can be separated from the connecting shaft 14 first, and the power assembly can be pushed away from the roller 3. Then, the turntable 7 and the connecting shaft 14 and the bearing connected to the turntable 7 are pushed away from the roller 3 by the first cylinder 13. Then, the turntable 7 is rotated to rotate another group of (clean) connecting shafts 14 and bearings to the position of the group of (to be cleaned) connecting shafts 14 and bearings. Then, the first cylinder 13 is started again, and the turntable 7 is driven by the first cylinder 13 to move toward the roller 3, so that the (clean) connecting shaft 14 is connected to the roller 3, and lubricating grease is added to the (clean) bearing. Then, the power assembly is reset, and the calender body 1 can be started again. Continue to carry out production work, and at this time the connecting shaft 14 and the bearing (to be cleaned) are inside the cleaning shell 5, and the external cleaning system will be connected to the nozzle 24, and the cleaning agent will be sprayed through the nozzle 24 to flush the deteriorated grease on the bearing (to be cleaned). After the flushing is completed, the external drying system can be connected to the nozzle 24 to dry the bearing to prevent the bearing from rusting. The cleaned bearing and connecting shaft 14 can wait for the next lubricating grease replacement and connect to the roller 3. The above operation steps can not only reduce the downtime of the calender body 1 and improve production efficiency, but also allow the connecting shaft 14 and the bearing to have sufficient time for cleaning. At the same time, the connection method between the bearing and the turntable 7 and the connecting shaft 14 is interference fit. In addition, the structure of the calender body 1 and the roller 3 in the present invention is similar to the prior art, and the three-roller calender structure disclosed in the patent with patent authorization announcement number CN220313961U is similar, so no further elaboration is made here.

[0033] As a preferred technical solution of the present invention, both ends of the roller 3 are fixedly connected with connecting blocks 4, the end of the connecting shaft 14 close to the roller 3 is fixedly connected with an insert block 16, the insert block 16 matches the connecting block 4, the insert block 16 and the connecting block 4 are fixed by bolts, and the end of the connecting shaft 14 away from the roller 3 is fixedly connected to the transmission gear 15, and the adjacent transmission gears 15 located on the same side of the turntable 7 are meshed with each other.

[0034] As a preferred technical solution of the present invention, a first motor 18 is fixedly connected to a side of the top of the support seat 2 away from the roller 3 , and a transmission shaft 19 matching the plug block 16 is fixedly connected to an output end of the first motor 18 .

[0035] Specifically, the (clean) connecting shaft 14 is connected to the connecting block 4 through the plug block 16, and after the plug block 16 is inserted into the connecting block 4, it can be reinforced by bolts to prevent the connecting shaft 14 from shaking when driving the roller 3 to rotate, and the (to be cleaned) connecting shaft 14 can be connected to the transmission shaft 19 through the plug block 16, and the first motor 18 can drive the connecting shaft 14 to rotate through the transmission shaft 19, thereby forming a stirring effect and improving the flushing effect of the nozzle 24.

[0036] As a preferred technical solution of the present invention, the bearing includes an inner ring 8, an outer ring 9 and a dustproof sheet 10, the connecting shaft 14 is connected to the inner wall of the inner ring 8, the outer wall of the outer ring 9 is connected to the turntable 7, a ball is provided between the inner ring 8 and the outer ring 9, the dustproof sheet 10 is located between the inner ring 8 and the outer ring 9, and the two dustproof sheets 10 are respectively located on both sides of the ball.

[0037] Specifically, after separating the connecting shaft 14 (to be cleaned) and the bearing from the connecting block 4, the dustproof sheets 10 on both sides of the bearing can be removed first, and then the turntable 7 can be rotated, so that the deteriorated grease on the bearing can be more easily washed away by the nozzle 24. In addition, the connection between the connecting shaft 14 and the inner ring 8 is an interference fit, and the connection between the outer ring 9 and the turntable 7 is an interference fit.

[0038] As a preferred technical solution of the present invention, a guide block 11 is fixedly connected to the bottom of the cleaning shell 5 , and guide grooves 12 matching the guide block 11 are provided at both ends of the top of the calender body 1 .

[0039] Specifically, in order to improve the sealing effect of the cleaning shell 5, a sealing gasket is provided at the contact position between the cleaning shell 5 and the turntable 7 (since the provision of a sealing gasket belongs to the existing mature technology, it is not described in detail in the present invention), which leads to a large friction between the turntable 7 and the cleaning shell 5. Therefore, when the turntable 7 is rotated, the cleaning shell 5 is easy to rotate together. By limiting the cleaning shell 5 through the guide groove 12 and the guide block 11, the cleaning shell 5 can be prevented from rotating together with the turntable 7.

[0040] As a preferred technical solution of the present invention, a connecting rod 30 is fixedly connected to the side of the output end of the first cylinder 13 close to the roller 3, a wedge block 29 is fixedly connected to the side of the connecting rod 30 away from the roller 3, a slide groove 25 is provided on the side wall inside the calender body 1, a slider 26 is slidably connected inside the slide groove 25, a support frame 27 matching the connecting block 4 is fixedly connected to the side of the slider 26 close to the roller 3, and a slot 28 matching the wedge block 29 is provided on the support frame 27.

[0041] Specifically, when the first cylinder 13 drives the turntable 7 to move away from the roller 3, the connecting rod 30 will also synchronously drive the wedge block 29 to move away from the roller 3. At this time, the wedge block 29 will gradually insert into the slot 28. Due to the wedge shape of the wedge block 29, the support frame 27 will be lifted up until the top of the support frame 27 abuts against the connecting block 4. At this time, the plug block 16 will also be separated from the connecting block 4. In this way, the support frame 27 can provide support for the connecting block 4 to prevent the roller 3 from being displaced, which makes it difficult for the subsequent plug block 16 to be inserted into the connecting block 4. It is worth noting that the cross-section of the end of the plug block 16 is smaller than the cross-section of the insertion hole on the connecting block 4. Therefore, if the connecting block 4 is displaced, as long as it does not exceed a certain range, the plug block 16 can be inserted into the connecting block 4.

[0042] As a preferred technical solution of the present invention, the power assembly includes a second cylinder 20, a mounting frame 21, a second motor 22 and a driving gear 23. The second cylinder 20 is fixedly connected to the calender body 1, the output end of the second cylinder 20 is fixedly connected to the mounting frame 21, the second motor 22 is fixedly connected to the mounting frame 21, the driving gear 23 is fixedly connected to the output end of the second motor 22, and the driving gear 23 is meshed with the transmission gear 15.

[0043] Specifically, when the calender body 1 is working normally, the second motor 22 drives the driving gear 23 to rotate, and the driving gear 23 drives one of the transmission gears 15 meshing with it to rotate, and the transmission gear 15 drives the other transmission gears 15 meshing with it to rotate, so that the second motor 22 can drive the roller 3 to rotate. Before replacing the lubricating grease, the second cylinder 20 will push the mounting frame 21, the second motor 22 and the driving gear 23 to move away from the roller 3 to avoid the second motor 22 and the driving gear 23 from having an adverse effect on the rotation of the turntable 7. At the same time, since the position of the connecting block 4 does not change each time, when the insert block 16 is inserted into the connecting block 4, if the insert block 16 is not aligned with the connecting block 4, it is necessary to move the transmission gear 15 to align the insert block 16 with the connecting block 4. This step can be regarded as calibration. After calibration, the transmission gear 15 will also be aligned with the driving gear 23. Therefore, when the second motor 22 and the driving gear 23 move toward the roller 3, the driving gear 23 can still mesh with the transmission gear 15.

[0044] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
