Description

Technical Field

[0001] This utility model relates to the field of corrugated board processing technology, and in particular to a corrugated board feeding and dust removal device. Background Technology

[0002] Corrugated paper is a sheet-like material made by bonding linerboard and corrugated paper formed by corrugating rollers. It is generally divided into two categories: single-wall corrugated paperboard and double-wall corrugated paperboard. According to the size of the corrugations, it is divided into five types: A, B, C, E, and F. Corrugated paper has been invented and used for more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printability, and convenient storage and handling. More than 80% of corrugated paper can be recycled. Corrugated paper can be used for packaging food or digital products. It is relatively environmentally friendly and widely used. However, during the use of corrugated paperboard, the surface of traditional corrugated paperboard does not have corresponding protective measures, which can easily lead to the surface of the corrugated paperboard absorbing moisture and causing foaming and damage.

[0003] In the existing technology, when stains appear on the surface of corrugated cardboard and cleaning is required, it is easy to wipe it with a damp cloth, which will cause the corrugated cardboard to become damp and damaged, making it impossible to clean effectively. On the one hand, it reduces the use effect of the corrugated cardboard, and on the other hand, it indirectly affects the cleanliness and appearance of the corrugated cardboard.

[0004] To address the aforementioned issues, an existing patent (publication number: CN221501594U) proposes a corrugated board feeding dust removal device. This device features U-shaped cardboard pieces at both the top and bottom of the double-layer corrugated board, and a cushioning cardboard piece at the center. The cushioning cardboard is fixedly connected to the U-shaped cardboard pieces at both the top and bottom. An angled cardboard piece is located inside the U-shaped cardboard pieces, and a cleaning coating layer is applied to the surface of the double-layer corrugated board. This design is structurally sound. By incorporating U-shaped cardboard pieces, cushioning cardboard, and angled cardboard, and by placing corresponding U-shaped cardboard pieces inside the double-layer corrugated board, and by placing cushioning cardboard pieces between the U-shaped cardboard pieces, along with the angled cardboard pieces inside the U-shaped cardboard pieces, the U-shaped cardboard, cushioning cardboard, and angled cardboard effectively ensure the strength of the double-layer corrugated board, minimizing its susceptibility to damage and bending.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, cleaning with a film-coated structure can easily result in incomplete or ineffective cleaning when encountering difficult-to-clean impurities. Furthermore, in mechanized production, the film can easily break during the film-coating process, requiring re-coating and increasing the time and difficulty of the work.

[0006] Therefore, a dust removal device for corrugated board feeding is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a corrugated board feeding and dust removal device that can solve the problems of incomplete cleaning of existing film coatings and the easy occurrence of film rupture affecting the progress of the operation.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a corrugated board feeding dust removal device, including a transfer base, an electrostatic dust collection mechanism movably connected to the inner side of the transfer base, and an auxiliary cleaning mechanism movably connected to the outer side of the electrostatic dust collection mechanism;

[0009] The electrostatic dust collection mechanism includes an electrostatic conveying roller, an electrostatic generator, a spacing adjustment component, and a material transfer tray. The spacing adjustment component is movably connected to the inner side of the transfer base, the top electrostatic conveying roller is movably connected to the inner side of the transfer base, the bottom electrostatic conveying roller is movably connected to the inner side of the spacing adjustment component, the electrostatic generator is movably connected to the outer side of the electrostatic conveying roller, and the material transfer tray is located on the right side of the transfer base.

[0010] Preferably, a collection trough is slidably connected to the inner side of the transfer base, the collection trough is slidably connected to the left side of the material transfer tray, and the collection trough is located at the bottom of the electrostatic conveying roller.

[0011] Preferably, a support frame is movably connected to the inner side of the spacing adjustment component, and a soft cleaning scraper is rotatably connected to the inner side of the support frame. The soft cleaning scraper is disposed at the bottom of the electrostatic conveying roller and at the top of the collection trough.

[0012] Preferably, a support strip is fixedly connected to the outer side of the support frame, and tension springs are fixedly connected to the outer sides of both the support strip and the soft cleaning scraper.

[0013] Preferably, sliding support blocks are movably connected to both sides of the bottom electrostatic conveying roller, the support frame is fixedly connected to the inner side of the sliding support blocks, and a telescopic pull frame is movably connected to the outer side of the sliding support blocks, the telescopic pull frame being movably connected to the inner side of the transfer base.

[0014] Preferably, a connecting arm is rotatably connected to the outer side of the telescopic frame, the connecting arm is rotatably connected to both sides of the material transfer tray, a limit plate is slidably connected to the bottom of the material transfer tray, and an electric ball screw is threadedly connected to the outer side of the material transfer tray, the electric ball screw is movably connected to the outer side of the limit plate and the transfer base.

[0015] Preferably, the left side of the transfer base is fixedly connected to the inlet.

[0016] Preferably, a dust removal port is provided on the left side of the collection tank.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application sets up an electrostatic dust collection mechanism to make the cleaning equipment for corrugated boards inclined for electrostatic adsorption cleaning. The dust on the surface of the corrugated board is adsorbed by an electrostatic conveying roller. The cleaning is completed when the corrugated board passes through the inclined surface. It is quick and convenient. Compared with the traditional dust suction cleaning of conveying pipe air inlet and film cleaning, the cleaning effect is further improved. There is no cumbersome work process and it does not affect the air permeability of the corrugated board. After cleaning, it can be quickly connected to the transfer equipment for the next processing step.

[0019] 2. This application improves the setting of an auxiliary cleaning mechanism, which can quickly clean the electrostatic conveying roller. When the electrostatic conveying roller rotates to transfer the corrugated board, the side with dust will raise the soft cleaning scraper at the bottom. Thus, when it rotates once, the soft cleaning scraper can scrape off the surface dust. When the electrostatic conveying roller rotates back to the transfer surface, it will be in a dust-free state, and the scraped dust will fall into the collection tank for collection, thereby preventing pollution of the working environment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A corrugated board feeding dust removal device includes a transfer base 1, an electrostatic dust collection mechanism 2 movably connected to the inner side of the transfer base 1, and an auxiliary cleaning mechanism movably connected to the outer side of the electrostatic dust collection mechanism 2; 3.

[0029] The electrostatic dust collection mechanism 2 includes an electrostatic conveying roller 21, an electrostatic generator 22, a spacing adjustment component 23, and a material transfer tray 24. The spacing adjustment component 23 is movably connected to the inner side of the transfer base 1, the top electrostatic conveying roller 21 is movably connected to the inner side of the transfer base 1, the bottom electrostatic conveying roller 21 is movably connected to the inner side of the spacing adjustment component 23, the electrostatic generator 22 is movably connected to the outer side of the electrostatic conveying roller 21, and the material transfer tray 24 is located on the right side of the transfer base 1.

[0030] In this embodiment: the electrostatic generator 22 can cause static electricity to be attached to the surface of the electrostatic conveying roller 21, which can be cleaned during the transfer of the corrugated board. Before the transfer, the spacing adjustment component 23 can be raised to adjust the spacing of the electrostatic conveying roller 21 to adapt to the length of the corrugated board, and the material transfer pallet 24 can be quickly lifted for transfer.

[0031] Specifically, such as Figure 2 , Figure 5 As shown, a collection trough 31 is slidably connected to the inner side of the transfer base 1. The collection trough 31 is slidably connected to the left side of the material transfer tray 24 and is located at the bottom of the electrostatic conveying roller 21.

[0032] Specifically, such as Figure 2 , Figure 5 As shown, a support frame 32 is movably connected to the inner side of the spacing adjustment component 23, and a soft cleaning scraper 33 is rotatably connected to the inner side of the support frame 32. The soft cleaning scraper 33 is located at the bottom of the electrostatic conveying roller 21 and at the top of the collection trough 31.

[0033] Specifically, such as Figure 2 , Figure 5 As shown, a support bar 34 is fixedly connected to the outside of the support frame 32, and tension springs 35 are fixedly connected to the outside of both the support bar 34 and the soft cleaning scraper 33.

[0034] In this embodiment: the soft cleaning scraper 33 at the bottom of the electrostatic conveying roller 21 is squeezed when the roller rolls, and the dust on its surface is scraped off to the bottom collection trough 31. When the soft cleaning scraper 33 is subjected to the rotational pressure of the electrostatic conveying roller 21, it rotates along the support frame 32 and stretches the tension spring 35 between it and the support bar 34. The tension spring 35 rebounds, making the scraper further fit with the electrostatic conveying roller 21 for better scraping. The support frame 32 and the sliding support block 23a are linked and can adjust the spacing with the telescopic outer frame. When the material transfer tray 24 moves inward, it will push the collection trough 31.

[0035] Specifically, such as Figure 3 , Figure 4 As shown, sliding support blocks 23a are movably connected to both sides of the bottom electrostatic conveying roller 21, and the support frame 32 is fixedly connected to the inner side of the sliding support block 23a. Telescopic pull frame 23b is movably connected to the outer side of the sliding support block 23a and is movably connected to the inner side of the transfer base 1.

[0036] Specifically, such as Figure 3 , Figure 4 As shown, a connecting arm 23c is rotatably connected to the outer side of the telescopic pull frame 23b. The connecting arm 23c is rotatably connected to both sides of the material transfer tray 24. A limit plate 23d is slidably connected to the bottom of the material transfer tray 24. An electric ball screw 23e is threadedly connected to the outer side of the material transfer tray 24. The electric ball screw 23e is movably connected to the outer side of the limit plate 23d and the transfer base 1.

[0037] In this embodiment: the material transfer tray 24 is driven to move on the limiting plate 23d by the electric ball screw 23e. The tray can be a transfer trolley for storing corrugated boards or a transfer base 1 for carrying the conveyor belt. When the tray moves, it drives the connecting arm 23c to rotate, pushing or pulling the telescopic bracket 23b to adjust the spacing of the electrostatic conveying roller 21. The telescopic bracket 23b is composed of multiple connecting rods connected in rotation. One end of the pulling point is movably connected to the inner wall of the transfer base 1 on both sides of the top electrostatic conveying roller 21, the other rotation points are connected to the sliding support block 23a, and the other force point is connected to the connecting arm 23c, so as to prevent the corrugated board from getting stuck or falling during transfer.

[0038] Specifically, such as Figure 1 , Figure 2 As shown, the feed inlet 4 is fixedly connected to the left side of the transfer base 1.

[0039] Specifically, such as Figure 2 As shown, a dust removal port 5 is provided on the left side of the collection tank 31.

[0040] In this embodiment: materials can be fed through the feed port 4, and dust in the collection tank 31 can be cleaned through the dust removal port 5.

[0041] Working principle: Before processing the corrugated board, the length and thickness of the corrugated board are confirmed, and the spacing of the electrostatic conveying rollers 21 for transferring the corrugated board is adjusted. The electric ball screw 23e drives the material transfer tray 24 to move on the limiting plate 23d. The material transfer tray 24 can be a transfer trolley for storing corrugated boards or a transfer base 1 that carries the conveyor belt. During the movement of the material transfer tray 24, the connecting arm 23c rotates, pushing or pulling the telescopic bracket 23b to extend or retract, thus adjusting the spacing of the electrostatic conveying rollers 21. 23b is composed of multiple connecting rods that rotate and connect. One end of the pulling point is movably connected to the inner wall of the transfer base 1 on both sides of the top electrostatic conveying roller 21, while the other rotating points are rotatably connected to the sliding support block 23a. The other force point is movably connected to the connecting arm 23c, thereby achieving the above effect and preventing the corrugated sheet from getting stuck or falling off during transfer via the electrostatic conveying roller 21. After adjusting the spacing, the electrostatic generator 22 is activated to attach static electricity to the electrostatic conveying roller 21. The corrugated sheet is then fed into the inner side of the transfer base 1 through the feed port 4, which has a larger opening at the top and a smaller opening at the bottom. This design facilitates placement and provides some guidance before the corrugated sheet enters the transfer base 1. Once inside the transfer base 1, the corrugated sheet, due to its inclined design, moves downwards through the inlet 4 via inertia and gravity. During this movement, the electrostatic conveying roller 21 rotates, adsorbing dirt from the corrugated sheet surface for cleaning. Simultaneously, a soft cleaning scraper 33 is attached to the bottom of the electrostatic conveying roller 21. As the roller rolls, it squeezes the scraper 33, causing surface dust to be scraped and fall into the bottom collection trough. 31. When the soft cleaning scraper 33 is subjected to the rotational pressure of the electrostatic conveying roller 21, it will rotate along the support frame 32 and stretch the tension spring 35 between the support bar 34, and rebound to further fit with the electrostatic conveying roller 21, achieving a better scraping effect. The support frame 32 is linked with the sliding support block 23a, and can adjust the spacing together with the telescopic outer frame. When the material transfer tray 24 moves inward, it will also push the collection trough 31, so that it can be adjusted according to the electrostatic conveying roller 21. Finally, after cleaning, it is transferred and processed by other transfer equipment, and the collection trough 31 is cleaned through the cleaning port 5.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
