Description

Technical Field

[0001] The utility model belongs to the technical field of printed products, and particularly relates to a paper feeding and dust removal device. Background Art

[0002] At present, the production process of printed products is generally carried out by corresponding equipment automation. The base paper processed by the previous station is continuously transported to the next station through the conveying device for the next processing. In some processing, a small amount of dust will inevitably adhere to the base paper, affecting the subsequent processing and causing corresponding printing defects. For example, when the base paper (composite paper) is produced by a multifunctional composite machine, a small amount of dust or other fine impurities will adhere to its surface. If the dust and other impurities are not processed, it will cause uneven glue coating when it is transported to the gluing station, thus affecting the quality of subsequent processing.

[0003] In order to solve the dust problem on the base paper, a dust removal device is set between two processing stations in the prior art. A common method is to use a dust scraping assembly to scrape off the dust. However, in actual use, the dust scraped off floats in the air and is easily attached to the surface of the base paper again, resulting in poor dust removal effect and efficiency. To this end, the prior art provides some dust removal devices combined with negative pressure adsorption, such as the Chinese patent with publication number CN216174529U. A negative pressure chamber is set in this type of dust removal device, and a paper passing hole for the base paper to pass through is opened on the side. Two sets of dust scraping assemblies are set in the negative pressure chamber. The base paper is passed through the paper passing hole and passes between the two dust scraping assemblies in the negative pressure chamber. The two dust scraping assemblies scrape off the dust on the surface of the base paper, and the negative pressure chamber sucks the floating dust to the outside. Due to structural limitations, this type of dust removal device is in a relatively closed state as a whole. When in use, the dust removal device must be arranged in place before the production line starts, so that the base paper can be guided to pass through the negative pressure chamber of the dust removal device during transportation. It is impossible to adjust the position of the dust removal device according to the actual dust removal needs during the production line production process or add dust removal devices at other locations, and the flexibility is low. In addition, with use, more dust will continue to adhere to the dust scraping component and the dust scraping surface will deform. Therefore, the dust scraping component needs to be replaced regularly to ensure the dust removal effect. However, since this type of device is in a relatively closed state as a whole, the operation of replacing the dust scraping component is relatively troublesome. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a paper feeding dust removal device which can ensure the dust removal effect on both sides of base paper, has higher flexibility in use, and is simpler and faster to operate in replacing the dust scraping assembly.

[0005] The content of the utility model includes a base, an exhaust hood and a dust scraping assembly. There are two exhaust hoods, one of which is installed on the base, and the other is detachably connected to the base or the exhaust hood installed on the base, and the exhaust surfaces of the two exhaust hoods are arranged opposite to each other. There are two dust scraping assemblies, and the exhaust surfaces of the two exhaust hoods are both provided with slots. The plug-in entrance of the slot is located on one side of the exhaust surface, and the two dust scraping assemblies are plugged into and matched with the slots on the exhaust surfaces of the two exhaust hoods.

[0006] Furthermore, a single dust scraping assembly includes a support plate and a plurality of dust scraping pieces. The dust scraping assembly is plugged into and matched with the slot through the support plate. The support plate is hollowed out, and the plurality of dust scraping pieces are arranged at intervals on the support plate, and the intervals between the plurality of dust scraping pieces correspond to the hollow positions of the support plate.

[0007] Furthermore, a circle of elastic sealing is arranged on the edge of the support plate, and when the support plate is plugged into the slot, the elastic sealing abuts against the inner wall of the slot.

[0008] Furthermore, several of the scraping members are sponges.

[0009] Furthermore, the plurality of scraping members are detachably connected to the support plate.

[0010] Furthermore, the plurality of scraping members are detachably connected to the support plate via an adhesive layer.

[0011] Furthermore, the plurality of scraping members are all strip-shaped, the length of a single scraping member is greater than the width of the base paper, and the plurality of scraping members are arranged at intervals on the support plate along the conveying direction of the base paper.

[0012] Furthermore, a circle of baffles is provided on the edges of the exhaust surfaces of the two exhaust hoods, and the ends of the baffles are bent inwardly. The baffles and the edges of the exhaust surfaces of the exhaust hoods form the slot together, and an opening is provided on one side of the baffle to form an insertion entrance of the slot.

[0013] Furthermore, it also includes a negative pressure fan, and the two exhaust hoods are connected with exhaust pipes, and the exhaust pipes on the two exhaust hoods are connected to the exhaust end of the same negative pressure fan.

[0014] Furthermore, when the two vacuum hoods are detachably connected, a cushion block is provided between the two vacuum hoods to form a gap between the two vacuum hoods for the base paper to pass through.

[0015] The beneficial effect of the utility model is that when in use, the base paper passes between the exhaust surfaces of the two exhaust hoods and between the two dust scraping assemblies, the two dust scraping assemblies scrape off the dust on both sides of the base paper, and the two exhaust hoods correspondingly suck the dust scraped off by the two dust scraping assemblies to the outside. The dust removal effect on both sides of the base paper is improved by adopting the scraping combined with suction method.

[0016] In the utility model, the dust on both sides of the base paper is sucked by two exhaust hoods respectively, and one exhaust hood is detachably connected to the base or the other exhaust hood. After the exhaust hood is removed, the two exhaust hoods are open. Even when the production line is in progress or paused, that is, when the base paper is already between two processing stations, the base paper can be moved as a whole through the moving device to pass between the two exhaust hoods, and then the removed exhaust hood is installed to the working position, so that the base paper between the two processing stations can be located between the exhaust surfaces of the two exhaust hoods and between the two scraping components to remove the dust from the base paper. Based on the existing production line in the workshop, the utility model can adjust the position of the dust removal device or add a dust removal device between the two processing stations according to the requirements of different printed products for the surface cleanliness of the base paper at different station nodes, and it is more flexible to use.

[0017] The two dust scraping assemblies correspond to the slots on the exhaust surfaces of the two exhaust hoods, and the insertion entrances of the slots are located on one side of the exhaust surface, so that the moving direction of the two dust scraping assemblies when plugged in is parallel to the direction of the exhaust surface. Therefore, the dust scraping assemblies can be taken out from the side of the exhaust hood while the exhaust hood remains installed, and then a clean dust scraping assembly can be inserted. Compared with the method of removing the exhaust hood and then replacing the dust scraping assemblies, the utility model can save the steps of disassembling and assembling the exhaust hood, and the operation of replacing the dust scraping assemblies is simpler, faster and more efficient.

[0023] like Figure 1-Figure 4As shown, the utility model provides a paper feeding and dust removal device, including a base 1, an exhaust hood 2 and a dust scraping assembly 3. The exhaust surface of the exhaust hood 2 is the side thereof used for sucking dust. The exhaust hood 2 has two exhaust hoods, one of which is mounted on the base 1, and the other exhaust hood 2 is detachably connected to the base 1, or is detachably connected to the exhaust hood 2 arranged on the base 1. The exhaust surfaces of the two exhaust hoods 2 are arranged opposite to each other, and there is a gap between the exhaust surfaces of the two exhaust hoods 2. The dust scraping assembly 3 is provided with two slots 22, and the insertion entrance of the slots 22 is located on one side of the exhaust surface. The two dust scraping assemblies 3 are correspondingly plugged into and matched with the slots 22 on the exhaust surfaces of the two exhaust hoods 2.

[0024] The paper feeding and dust removal device provided by the utility model, when in use, base paper passes between the air suction surfaces of the two exhaust hoods 2 and between the two dust scraping components 3, the two dust scraping components 3 scrape off the dust on both sides of the base paper, and the two exhaust hoods 2 correspondingly suck the dust scraped off by the two dust scraping components 3 to the outside, and the dust removal effect on both sides of the base paper is improved by adopting the scraping combined with suction method.

[0025] In the present invention, the dust on both sides of the base paper is sucked by two exhaust hoods 2 respectively, and one exhaust hood 2 is detachably connected to the base 1 or the other exhaust hood 2. After the exhaust hood 2 is removed, the space between the two exhaust hoods 2 is open. Even when the production line is in progress or paused, that is, when the base paper is already between two processing stations, the base paper can be moved as a whole through the moving device to pass between the two exhaust hoods 2, and then the removed exhaust hood 2 is installed to the working position, so that the base paper between the two processing stations can be located between the exhaust surfaces of the two exhaust hoods 2 and between the two scraping components 3 to remove the dust from the base paper. Compared with the method of setting a negative pressure chamber with a scraping component 3 in the device and letting the base paper pass through the negative pressure chamber for dust removal, the present invention can be based on the existing production line in the workshop, and according to the requirements of different printed products on the surface cleanliness of the base paper at different station nodes, the position of the dust removal device can be adjusted or a dust removal device can be added between the two processing stations, which is more flexible to use.

[0026] The two dust scraping assemblies 3 are plugged into and matched with the slots 22 on the exhaust surfaces of the two exhaust hoods 2, and the plug-in entrances of the slots 22 are located on one side of the exhaust surface, so that the moving direction of the two dust scraping assemblies 3 when plugged in is parallel to the direction of the exhaust surface. Therefore, the dust scraping assembly 3 can be taken out from the side of the exhaust hood 2 while the exhaust hood 2 is kept installed, and then a clean dust scraping assembly 3 can be inserted. Compared with the method of replacing the dust scraping assembly 3 after removing the exhaust hood 2, the utility model can save the steps of disassembling and assembling the exhaust hood 2, and the operation of replacing the dust scraping assembly 3 is simpler, faster and more efficient.

[0027] A single scraping assembly 3 includes a support plate 31 and a plurality of scraping pieces 32, and the support plate 31 is plugged and matched with the corresponding slot 22, that is, the scraping assembly 3 is plugged and matched with the corresponding slot 22 through the support plate 31, and the support plate 31 is hollowed out, and a plurality of scraping pieces 32 are arranged at intervals on the support plate 31, and the intervals between the plurality of scraping pieces 32 correspond to the hollowed-out positions of the support plate 31. In this arrangement, the scraping assembly 3 can have a sufficient scraping working surface, and the exhaust hood 2 can be ensured to normally perform suction toward the surface of the base paper.

[0028] In the present invention, a circle of elastic seal is arranged at the edge of the support plate 31. When the support plate 31 is plugged into the corresponding slot 22, the elastic seal abuts against the inner wall of the slot 22. The elastic seal is specifically rubber. This arrangement can improve the tightness of the support plate 31 after plugging, and prevent the scraper assembly 3 from being displaced due to the friction of the scraper 32 with the base paper.

[0029] In some embodiments of the present invention, the plurality of scraping members 32 are brushes. In a preferred embodiment of the present invention, the plurality of scraping members 32 are sponges. Compared with brushes, sponges have softer surfaces and are less likely to leave scratches on the surface of the base paper and affect subsequent processing of the base paper.

[0030] In one embodiment of the utility model, several scraping members 32 and the support plate 31 are integrally arranged. In a preferred embodiment of the utility model, several of the scraping members 32 and the support plate 31 are detachably connected. After replacing the scraping assembly 3, the support plate 31 in the replaced scraping assembly 3 can be reused, saving costs.

[0031] The scraping members 32 are detachably connected to the support plate 31 through an adhesive layer. For example, when the scraping member 32 is a sponge, after setting the adhesive layer on the sponge or the support plate 31, the sponge can be glued on, and when the sponge needs to be removed, the sponge can be torn off. This arrangement is convenient and quick to disassemble the scraping member 32. The adhesive layer can be double-sided tape or other materials.

[0032] like Figure 4 As shown, the specific arrangement of the support plate 31 and the plurality of scrapers 32 is that the plurality of scrapers 32 are all strip-shaped, the length of a single scraper 32 is greater than the width of the base paper, and the plurality of scrapers 32 are arranged at intervals on the support plate 31 along the conveying direction of the base paper, and the area on the support plate 31 corresponding to the intervals between the plurality of scrapers 32 is a hollow arrangement. The plurality of scrapers 32 can scrape off the dust on the surface of the base paper in sequence, and the scraped dust is sucked to the outside by the exhaust hood 2 in the area between the two scrapers 32. This arrangement can satisfy the need for multiple scraping operations on a single side of the base paper under the condition of a single exhaust hood 2, and can also ensure normal dust suction.

[0033] like Figure 3 As shown, the specific arrangement of the slot 22 is that a circle of baffles 21 are provided on the edges of the exhaust surfaces of the two exhaust hoods 2, an opening is provided on one side of the baffle 21, and the end of the baffle 21 is bent inwardly, and the baffle 21 and the edge of the exhaust surface of the exhaust hood 2 form the slot 22 together, and an opening is provided on one side of the baffle 21 to form a plug-in entrance of the slot 22.

[0034] The utility model also includes a negative pressure fan, and the two exhaust hoods 2 are both connected with an exhaust pipe 4, and the exhaust pipes 4 on the two exhaust hoods 2 are connected to the exhaust end of the same negative pressure fan, and the air outlet end of the negative pressure fan is connected to an external dust collection device. In this arrangement, the two exhaust hoods 2 share one negative pressure fan, reducing the number of negative pressure fans arranged.

[0035] In the utility model, mounting bosses are provided on both sides of the two exhaust hoods 2, and mounting plates are vertically provided on both sides of the base 1. The mounting bosses on both sides of one exhaust hood 2 are fixed to the mounting plates on both sides of the base 1, so as to be installed on the base 1, and the mounting bosses on both sides of the other exhaust hood 2 are bolted to the mounting plates on both sides of the base 1, or are bolted to the mounting platforms on both sides of the previous exhaust hood 2, so as to be detachably connected to the base 1 or the exhaust hood 2 installed on the base 1. When the two exhaust hoods 2 are detachably connected, a cushion block is provided between the two exhaust hoods 2, and the cushion block is specifically located between the mounting bosses on both sides of the two exhaust hoods 2. When the mounting bosses on both sides of the two exhaust hoods 2 are connected by bolts, due to the provision of the cushion block, it can be ensured that a corresponding gap can be formed between the two exhaust hoods 2 after they are connected, so as to allow the base paper to pass normally.
