Description

Technical Field

[0001] The invention relates to the technical field of paper cup making equipment, and in particular to a rubber roller waste rejection device for a paper cup laminating machine. Background Art

[0002] The waste rejection device for the rubber roller of the paper cup laminating machine is a device specially designed to remove waste from the rubber roller. Its working principle is that the plastic particles are first plasticized by a screw extruder, and then these plasticized materials are evenly extruded in a linear manner by the extrusion laminating head and tightly adhere to the surface of flexible substrates such as paper, film, non-woven fabrics, and woven fabrics. Then, these substrates with laminating films will be further compounded with auxiliary materials.

[0003] However, in the process of laminating the base material and auxiliary materials by the laminating machine, a common problem is that when the rubber material extruded from the laminating head is laminarized onto the composite surface of the base material, some residual rubber material is often left outside the edges of both sides of the base material. These residual rubber materials will quickly adhere to the roller surface of the composite rubber roller to form a circle of raised parts, and will soon solidify and freeze. This phenomenon will cause the contact gap between the composite steel roller and the composite rubber roller to change, which will have a serious impact on the composite quality and may cause the product quality to fail to meet the standards.

[0004] To address this problem, the traditional method is that the operator needs to manually insert a scraper or other tool into the gap of the equipment to scrape off the waste on the rubber roller. However, this method has many shortcomings: first, the operation process is cumbersome and laborious; second, since the operator needs to insert his hand into the equipment, this greatly increases the safety hazard during the operation, and the operator may be injured if he is not careful. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the operation process is complicated and laborious, and secondly, since the operator needs to put his hands into the equipment, this greatly increases the safety hazard during the operation and may cause harm to the operator if he is not careful.

[0016] An inclined surface is provided on the outer periphery of the abutting block, and an inclined surface is provided on one side of the sliding block, and the inclined surface abuts against the inclined surface.

[0017] As a further description of the above technical solution:

[0018] The switching assembly includes a mounting frame fixedly connected to one side of the connecting plate, and a motor is installed inside the mounting frame, an output end of the motor is connected to a rotating shaft, an outer periphery of the rotating shaft is fixedly connected to a rotating disk, a side of the connecting plate away from the mounting frame is fixedly connected to the rotating shaft, and the outer periphery of the rotating shaft is also rotatably connected to the rotating disk, the two rotating disks are connected by an elastic member, and a transmission member is connected between the rotating disk away from the mounting frame and the rotating shaft.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] The steps for dealing with the residual rubber on the surface of the rubber roller are as follows: first, start the driving source of the paper cup laminating machine to rotate the rubber roller, then start the electric push rod to push the connecting sleeve block up, drive the lifting rod to slide in the lifting groove, and then move the lifting plate and the scraper on it to clean the rubber on the periphery of the rotating rubber roller;

[0027] To protect the scraper, when the scraper contacts the hardened rubber, it moves in the sliding groove, compressing the telescopic spring and the extrusion spring at the same time. As the degree of compression increases, the scraper becomes more stable in the sliding groove and scrapes the hardened rubber more effectively. The abutment block gradually contracts under the slope of the limiting groove. When it completely leaves the sliding groove, the telescopic spring rebounds and pushes the abutment block into limiting grooves of different heights to prevent the scraper from moving further downward. The direct impact of the hardened rubber on the scraper is mitigated by the decreasing impact force in sequence.

[0028] In order to improve the processing effect, extrusion springs with different rigidity can be switched according to the hardness of the rubber. By starting the motor, the rotating shaft and the rotating disk are driven to rotate. The other rotating disk is rotated synchronously through the transmission of the connecting frame, the rotating sleeve rod and the rotating rod. The main gear drives the connecting gear to rotate, and then drives the secondary gear to rotate. This precision transmission ensures the stability of the connecting frame. As the rotating disk continues to rotate, extrusion springs with different rigidity are brought to the working position in turn, and the lower pressure plate connected to it contacts the scraper. In this way, according to the rubber of different hardness, the appropriate extrusion spring can be selected to optimize the scraping effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] like Figure 1-Figure 8 As shown, a paper cup laminating machine rubber roller rejecting device provided by the present invention comprises a frame 10, the frame 10 comprises a bottom frame 11, a composite roller 12 and a rubber roller 13 are installed on the top of the bottom frame 11, and also comprises: a scraping assembly 20 assembled on the top of the bottom frame 11, the scraping assembly 20 comprises two fixed frames 21 fixedly connected to the top of the bottom frame 11, the insides of the two fixed frames 21 are both provided with lifting grooves 211, and the inner walls of the lifting grooves 211 are both slidably connected with lifting rods 212, the outer periphery of the lifting rods 212 is fixedly connected with a connecting sleeve block 23, and an electric push rod 24 is installed between the connecting sleeve block 23 and the top of the bottom frame 11, the outer periphery of the two lifting rods 212 is connected with a connecting plate 22, the top of the connecting plate 22 is connected with a lifting plate 25, and the lifting plate 25 is slidably connected with a scraper 26 through a sliding groove 251, and the bottom of the scraper 26 extends out of the connecting plate 22 and is connected to the switching assembly 40;

[0044] When dealing with the rubber material remaining on the surface of the rubber roller 13, the operating steps are as follows: first, start the driving source of the paper cup laminating machine to drive the rubber roller 13 to start rotating. When the rubber roller 13 enters the rotating state, immediately start the electric push rod 24 to extend. The extension action of the electric push rod 24 will push the connecting sleeve 23 to rise synchronously. At the same time, the rise of the connecting sleeve 23 will drive the lifting rod 212 to slide smoothly inside the lifting groove 211. With the lifting and lowering movement of the lifting rod 212, the lifting plate 25 on the top of the connecting plate 22 will also move synchronously. Finally, the lifting plate 25 will drive the scraper 26 inside it to effectively clean the rubber material remaining on the periphery of the rotating rubber roller 13.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a buffer assembly 30 is installed inside the lifting plate 25, and the buffer assembly 30 includes a limiting member and a release member connected to the inside of the scraper 26. The limiting member includes a plurality of limiting grooves 31 opened on one side of the lifting plate 25, and an inner cavity 32 opened inside the scraper 26. The inner cavity 32 is slidably connected to an abutment block 321 in contact with the limiting groove 31, and a telescopic spring 322 is connected between the abutment block 321 and the inner cavity 32. The side of the plurality of limiting grooves 31 in contact with the abutment block 321 is set to be inclined, and the limiting groove 31 at the bottom is set to be square. The release member includes a plurality of limiting grooves 31 opened on one side of the lifting plate 25, and an inner cavity 32 opened inside the scraper 26. The invention comprises a slot 33 provided inside the scraper 26 and a through slot 331 penetrating the lifting plate 25, a positioning rod 34 is fixedly connected to one side of the slot 33, and a sliding block 341 is slidably connected to the outer periphery of the positioning rod 34, and the sliding block 341 is slidably connected to the slot 33, a compression spring 343 is sleeved on the outer periphery of the positioning rod 34, a toggle rod 344 extending from the through slot 331 is connected to one side of the sliding block 341, an inclined surface 323 is provided on the outer periphery of the abutting block 321, and an inclined surface 342 is provided on one side of the sliding block 341, and the inclined surface 342 abuts against the inclined surface 323;

[0046] When processing the rubber on the surface of the rubber roller 13, as the scraper 26 gradually approaches the residual rubber, especially the rubber that has hardened due to long-term storage, special measures need to be taken to protect the scraper 26 from damage during long-term work. In order to avoid damage caused by direct contact between the scraper 26 and the hardened rubber, a set of mechanisms is designed: when the scraper 26 contacts the hardened rubber, the hardness of the rubber will prompt the scraper 26 to move in the preset sliding groove 251. At the same time, as the scraper 26 descends, the slope of the limiting groove 31 thereon will push the abutment block 321 to move in the inner cavity 32, thereby compressing the telescopic spring 322. As the scraper 26 continues to descend, it will also push the lower pressure plate 468 to slide in the groove and compress the extrusion spring 467. The higher the compression degree of the extrusion spring 467, the stronger its resilience on the scraper 26, thereby making the scraper 26 more stable in the sliding groove 251 and more effectively scraping off the hardened rubber.

[0047] When the abutment block 321 is continuously lowered, it will gradually shrink under the action of the slope of the limiting groove 31. When the abutment block 321 is completely out of contact with the sliding groove 251, the telescopic spring 322 in the compressed state will rebound, pushing the abutment block 321 into the limiting grooves 31 at different heights. When the abutment block 321 enters the limiting groove 31 at the lowest position under the push of the rubber material, the limiting groove 31 will fix the abutment block 321, thereby preventing the scraper 26 from moving further downward. At this time, the fixed scraper 26 is used to process the hardened rubber material with a higher degree of hardening. The above-mentioned impact force is gradually reduced to slow down the direct impact of the hardened rubber material on the scraper 26, thereby minimizing the damage to the scraper 26 and extending its service life.

[0048] After processing the rubber roller 13, if you need to release the restriction on the scraper 26, you can do so by moving the toggle rod 344. The toggle rod 344 will drive the sliding block 341 to move in the slot 33. At the same time, the movement of the sliding block 341 on the outer periphery of the positioning rod 34 will stretch the compression spring 343. As the sliding block 341 moves, its inclined surface 342 will abut the inclined surface 323 of the abutting block 321, so that the abutting block 321 moves in the inner cavity 32 and breaks away from the restriction of the limiting groove 31. Subsequently, the extrusion spring 467 in the compressed state will rebound, pushing the scraper 26 to move in the sliding groove 251 and reset. After resetting, release the toggle rod 344, and the compression spring 343 in the stretched state will rebound, pulling the sliding block 341 to reset and break away from the contact with the abutting block 321, so that the sliding block 341 returns to its initial state and is ready for the next operation.

[0049] like Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown, the switching assembly 40 includes a mounting frame 41 fixedly connected to one side of the connecting plate 22, and a motor 42 is installed inside the mounting frame 41, an output end of the motor 42 is connected to a rotating shaft 43, and a rotating disk 45 is fixedly connected to the outer periphery of the rotating shaft 43, a rotating shaft 44 is fixedly connected to the side of the connecting plate 22 away from the mounting frame 41, and the outer periphery of the rotating shaft 44 is also rotatably connected to the rotating disk 45, the two rotating disks 45 are connected by an elastic member, a transmission member is connected between the rotating disk 45 away from the mounting frame 41 and the rotating shaft 44, the transmission member includes a main gear 46 fixedly connected to the outer periphery of the rotating shaft 44, a plurality of connecting rods 461 are rotatably connected inside the rotating disk 45 away from the mounting frame 41, and the outer periphery of each connecting rod 461 is connected to a connecting gear 462, and the rotating disk 45 away from the mounting frame 41 is connected to the rotating shaft 44. 1, a plurality of rotating rods 463 are rotatably connected inside the rotating disk 45, and a sub-gear 464 is connected to the outer periphery of the rotating rod 463, and the sub-gear 464 is meshed with the connecting gear 462, and the connecting gear 462 is meshed with the main gear 46, and the elastic member includes a plurality of rotating sleeve rods 465 rotatably connected to one side of the rotating disk 45 close to the mounting frame 41, and a rotating sleeve rod 465 is also fixedly connected to the outer periphery of each rotating rod 463, and a connecting frame 466 is connected between two rotating sleeve rods 465 on the same horizontal line, and a groove is provided inside the connecting frame 466, and a lower pressure plate 468 in contact with the scraper 26 is slidably connected to the inner wall of the groove, and a plurality of extrusion springs 467 are connected between the lower pressure plate 468 and the groove, and the stiffness of the extrusion spring 467 inside each connecting frame 466 is different;

[0050] When processing rubber materials of different hardness, in order to improve the processing effect, adaptive adjustment is achieved by switching the extrusion springs 467 with different rigidities. The specific operation of this process is as follows: first, the motor 42 is started, and the motor 42 then drives the rotating shaft 43 to start rotating. As the rotating shaft 43 rotates, the rotating disk 45 connected thereto also rotates synchronously. The rotating disk 45 further transmits and drives another rotating disk 45 on the periphery of the rotating rod 463 to rotate synchronously through the rotating sleeve rods 465 on both sides of the connecting frame 466 thereon;

[0051] During this rotation process, since the main gear 46 is fixed, it acts as a driving source to drive the connecting gear 462 meshing therewith to rotate, and the rotation of the connecting gear 462 causes the sub-gear 464 to rotate synchronously through the transmission effect. This precise transmission cooperation between the connecting gear 462 and the sub-gear 464 ensures that even if the rotating disk 45 is rotating, the connecting frame 466 can always maintain a positive upward stable posture. At the same time, the meshing action between the sub-gear 464 and the connecting gear 462 effectively prevents the possible shaking of the connecting frame 466, thereby ensuring the stability of the system.

[0052] Finally, with the continuous rotation of the rotating disk 45, the extrusion springs 467 of different rigidities are brought to the working position in turn, and the lower pressure plate 468 connected thereto contacts the scraper 26. In this way, according to the different hardness of the rubber, a suitable extrusion spring 467 can be selected to optimize the scraping effect, thereby improving the processing capacity for rubbers of different hardness.

[0053] Working principle: The steps for processing the residual rubber on the surface of the rubber roller 13 are as follows: first, start the driving source of the paper cup laminating machine to rotate the rubber roller 13, then start the electric push rod 24 to extend, push the connecting sleeve 23 and the lifting rod 212 to slide in the lifting groove 211, drive the lifting plate 25 and the scraper 26 to rise, and clean the outer periphery of the rotating rubber roller 13;

[0054] In order to protect the scraper 26, a buffer mechanism is designed: when the scraper 26 encounters hardened rubber, it moves in the sliding groove 251, and compresses the telescopic spring 322 and the extrusion spring 467 at the same time. The higher the compression degree of the extrusion spring 467, the stronger the resilience of the scraper 26, so that it can scrape the hardened rubber more stably. Under the action of the limiting groove 31, the abutment block 321 can prevent the scraper 26 from excessively moving downward, and reduce the impact of the hardened rubber on the scraper 26 by the decreasing impact force, thereby extending the service life.

[0055] To improve the processing effect, the extrusion springs 467 of different rigidities can be switched according to the hardness of the rubber material. The specific operation is: start the motor 42, drive the rotating shaft 43 and the rotating disk 45 to rotate, through the synchronous rotation of the connecting frame 466, the rotating sleeve 465 and the other rotating disk 45, and the precise transmission coordination of the main gear 46, the connecting gear 462 and the sub-gear 464, ensure that the connecting frame 466 is stable and does not shake, and finally the extrusion springs 467 of different rigidities are brought to the working position in turn, and the appropriate extrusion spring 467 is selected to optimize the scraping effect and improve the processing ability of rubber materials with different hardness.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
