Description

Technical Field

[0001] The utility model relates to the technical field of fresh-keeping film winding, in particular to a purging and dust-removing device for fresh-keeping film winding. Background Technique

[0002] In the production and packaging process of fresh-keeping film, the winding of fresh-keeping film is a crucial link. As a material widely used in food packaging, household freshness preservation and other fields, the surface cleanliness of fresh-keeping film is directly related to food safety and consumer health. During the winding process of fresh-keeping film, due to various factors such as the production environment, equipment operation, and raw material processing, dust, particles and other impurities are likely to adhere to the surface of fresh-keeping film.

[0003] For example, an automatic winding device for fresh-keeping film production (publication number: CN218595635U). Through the setting of the first cleaning brush and the second cleaning brush, since a telescopic spring is arranged between the first cleaning brush and the second cleaning brush, the fresh-keeping film can be placed between the first cleaning brush and the second cleaning brush through the elastic action of the telescopic spring. When the fresh-keeping film is wound, the first cleaning brush and the second cleaning brush can clean the dust particles adsorbed on the surface of the fresh-keeping film, avoiding dust adhesion on the fresh-keeping film and affecting the quality.

[0004] However, the device still has the following defects:

[0005] When the above device is used, the cleaning brush is used to clean the surface of the fresh-keeping film. During the process that the bristles of the cleaning brush are in contact with the fresh-keeping film for a long time and clean its surface, a large amount of dust, fibers and other impurities will inevitably be adsorbed and accumulated. With the accumulation of these impurities, the dust-removing effect of the cleaning brush will be significantly reduced, and even the adsorbed dust may be re-brought to the surface of the fresh-keeping film, forming secondary pollution. This not only fails to effectively solve the cleaning problem of the surface of the fresh-keeping film, but may even exacerbate its pollution degree. Therefore, we need to propose a purging and dust-removing device for fresh-keeping film winding. Content of the Utility Model

[0006] The purpose of the utility model is to provide a purging and dust-removing device for fresh-keeping film winding, aiming to solve the problem that during the process that the bristles of the cleaning brush in the prior art are in contact with the fresh-keeping film for a long time and clean its surface, a large amount of dust, fibers and other impurities will inevitably be adsorbed and accumulated.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0026] A blowing and dust-removing device for wrapping plastic film, comprising a dust-removing box 1. An operation port can be opened on one side of the dust-removing box 1, and a sealing door is arranged on one side of the operation port. Opening the sealing door facilitates the staff to set the plastic film to be dust-removed on the tensioning roller and the guiding roller through the operation port.

[0027] Two groups of cleaning brushes 3 are fixedly installed inside the feeding port 2 opened on one side wall of the dust-removing box 1. By setting the dust-removing box 1, the feeding port 2 and the cleaning brushes 3 in cooperation, the two groups of cleaning brushes 3 can scrape the dust and other impurities adhered to the surface of the plastic film, scrape up the stubborn dust adhered to the surface of the plastic film while pre-cleaning its surface, reduce the adhesion force of the dust and other impurities to the plastic film, facilitate subsequent blowing and cleaning, and is beneficial to improving the cleaning effect.

[0028] Two groups of blowing components 4 for cleaning the dust on the surface of the plastic film are symmetrically arranged inside the dust-removing box 1. By setting the blowing components 4, the impact force and shear force generated by the high-speed air flow are utilized to quickly blow off the dust and particles on the surface of the plastic film, so as to clean the dust on the surface of the plastic film.

[0029] A negative pressure port 5 is opened on the top of the dust-removing box 1, and an adsorption component 6 for collecting the floating dust after cleaning is arranged inside the negative pressure port 5. By setting the negative pressure port 5 and the adsorption component 6 in cooperation, it plays a role in adsorbing and collecting the dust and other particulate impurities blown up by the blowing, thus effectively avoiding the problem of secondary pollution to the cleaned plastic film, and is beneficial to further improving the cleaning effect of the plastic film;

[0030] The blowing component 4 includes an air pump 401. The air pump 401 is fixedly installed on one side wall of the dust-removing box 1. One end of the air pump 401 is fixedly communicated with an elbow pipe 402, and one end of the elbow pipe 402 penetrates through the dust-removing box 1 and is fixedly communicated with a blowing hood 403;

[0031] By adopting the above case, through the cooperation of the air pump 401, the elbow pipe 402 and the blowing hood 403, the working air pump 401 can convey the high-speed air flow to the inside of the blowing hood 403 through the elbow pipe 402, and then blow it out through the blowing hood 403. By using the impact force and shear force generated by the high-speed air flow, the dust and particles on the surface of the plastic film are quickly blown off, so as to clean the dust on the surface of the plastic film;

[0032] An air filter 404 is also included. The air filter 404 is connected in conduction with the elbow pipe 402, and the air filter 404 is fixedly installed on the top of the dust-removing box 1. By setting the air filter 404, it plays a role in filtering the impurities and particles in the high-speed air flow, so as to ensure the cleanliness of the blowing air and is beneficial to improving the cleaning effect of the plastic film;

[0033] Both groups of air blowing covers 403 are fixedly installed on the inner wall of the dust cleaning box 1, and the air outlet ends of the two groups of air blowing covers 403 are arranged oppositely. The two groups of air blowing covers 403 are respectively located at the top and bottom of the plastic wrap, so that the top and bottom of the plastic wrap can be blown to remove dust, which is beneficial to further improving the cleaning effect;

[0034] The adsorption assembly 6 includes an adsorption cover 601. The adsorption cover 601 is fixedly embedded inside the negative pressure port 5. A first connecting pipe 602 is fixedly connected to the top of the adsorption cover 601. One end of the first connecting pipe 602 is fixedly connected to a vacuum pump 603, and one end of the vacuum pump 603 is fixedly connected to a second connecting pipe 604;

[0035] It also includes a dust removal device body 605. The dust removal device body 605 is fixedly installed on one side wall of the dust cleaning box 1. The bottom end of the second connecting pipe 604 is fixedly connected to the top of the dust removal device body 605. Through the adsorption system and filtration mechanism inside it, the dust removal device body 605 can efficiently adsorb and fix the fine dust particles generated during the winding process of the plastic wrap, preventing the dust from spreading into the air and causing secondary pollution. While adsorbing the dust, the dust removal device body 605 can also purify the gas passing through it to a certain extent, reduce the dust concentration in the air, and improve the air quality of the production workshop;

[0036] By adopting the above case, through the combined use of the vacuum pump 603, the adsorption cover 601, the first connecting pipe 602, the second connecting pipe 604 and the dust removal device body 605, the working vacuum pump 603 can provide a negative pressure environment for the inner cavity of the adsorption cover 601, so as to adsorb and collect the dust and other particulate impurities floating inside the dust cleaning box 1, and transport them to the inside of the dust removal device body 605 through the first connecting pipe 602 and the second connecting pipe 604, thus effectively avoiding the problem of secondary pollution to the cleaned plastic wrap, which is beneficial to further improving the cleaning effect of the plastic wrap;

[0037] Three groups of tension rollers 7 are rotatably installed on the inner walls on both sides of the dust cleaning box 1. The three groups of tension rollers 7 are arranged alternately up and down. By applying an appropriate tension, the tension rollers 7 can ensure that the plastic wrap maintains a certain tension state inside the dust cleaning box 1, thus avoiding wrinkles or misalignment caused by slackness during the winding process of the plastic wrap, improving the flatness and tightness of the winding, maintaining the stable tension of the plastic wrap, and also helping to reduce the winding error caused by uneven tension, ensuring the consistency of the winding quality. In addition, during the winding process of the plastic wrap, if the plastic wrap is too slack, it is easy to cause relative sliding on the transmission belt or transmission chain, thereby reducing the transmission efficiency and increasing the energy loss. The tension rollers 7 can maintain the close contact between the plastic wrap and the transmission components by adjusting the tension, reduce the sliding phenomenon, and improve the transmission efficiency;

[0038] On the inner walls on both sides of the dust cleaning box 1, two groups of guide rollers 8 are rotatably installed. An outlet 9 is provided on one side wall of the dust cleaning box 1. The main function of the guide roller 8 is to guide the plastic wrap to wind according to a predetermined path. During the winding process of the plastic wrap, the guide roller 8 can ensure that the plastic wrap maintains a stable moving track in each link such as blowing dust cleaning and winding, avoiding problems such as uneven winding, dislocation or knotting caused by path deviation. The smooth surface and reasonable layout of the guide roller 8 help to reduce the resistance and friction of the plastic wrap during movement, enabling the plastic wrap to smoothly pass through the dust cleaning box and complete the winding action. This not only improves the winding efficiency but also ensures the winding quality, making the plastic wrap wind more tightly and smoothly.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
