Description

Technical Field

[0001] This utility model relates to a dust collection device for label backing paper, and more particularly to a dust collection device for label backing paper after drying. Background Technology

[0002] In the manufacturing process of label materials, silicone coating and drying are critical steps. After drying, the surface of the backing paper often absorbs or retains tiny impurities such as dust and fibers present in the production environment. If these impurities are not removed, they will directly affect the quality of subsequent processes (such as silicone coating, printing, or lamination), leading to product defects and reduced yield.

[0003] Currently, common methods for cleaning dried backing paper include using fixed brushes or negative pressure vacuuming devices. While fixed brushes are simple in structure, they don't make sufficient contact with backing paper that has slight warping or wavy edges, easily leaving cleaning dead spots and limiting dust removal effectiveness. Negative pressure vacuuming alone is insufficient for removing firmly attached particles. Furthermore, to enhance cleaning, a process of immediately flattening after cleaning is sometimes used; however, existing flattening roller gap adjustments are inconvenient, making it difficult to quickly adapt to backing paper of different thicknesses, and there is a risk of excessive pressure damaging the material or insufficient pressure resulting in poor flattening.

[0004] Therefore, the main problem in the existing technology is: how to achieve efficient dust removal of the dried backing paper and how to perform effective and non-damaging flattening treatment of the backing paper after cleaning, so as to meet the requirements of modern production lines for high efficiency and high quality. Utility Model Content

[0005] The main objective of this invention is to provide a dust collection device after the label backing paper has been dried, in order to solve the problems raised in related technologies.

[0006] To achieve the above objectives, according to one aspect of the present invention, a dust collection device for dried label backing paper is provided, comprising a housing with a slot on the housing, through which the dried backing paper passes.

A fixed roller is slidably disposed within the slot near the end of the backing paper's forward direction, and two fixed seats are symmetrically fixedly disposed on the housing. A pressure roller for flattening the backing paper is slidably disposed between the two fixed seats, the pressure roller being located directly above the fixed roller, and the backing paper passing between the fixed roller and the pressure roller.

[0007] Furthermore, the upper ends of both the fixing plate and the connecting plate are arc-shaped, the fixing plate has a groove, the connecting plate is slidably installed in the groove, the fixing plate has symmetrical connecting grooves communicating with the groove on both sides, and the fixing plate has sliding grooves communicating with the groove at both ends of the groove.

[0008] Furthermore, connecting rods are fixedly connected to both ends of the connecting plate, and the connecting rods are slidably disposed in the groove. Several springs are symmetrically fixedly disposed in the groove, with one end of the spring fixedly connected to the inner wall of the groove and the other end fixedly connected to the side wall of the connecting plate.

[0009] Furthermore, the chassis has elongated slots on both sides of the slot, which communicate with the slots. A lead screw is rotatably installed in the elongated slots. Slider blocks are fixedly connected to both ends of the fixed plate. The sliders are slidably installed in the elongated slots, and the lead screw passes through the sliders and is threadedly connected to them.

[0010] Furthermore, a mounting plate is fixedly installed below the slot, and several through holes are opened through the mounting plate. An air extraction chamber is opened inside the chassis below the mounting plate. An air extraction machine is fixedly installed on the outside of the chassis. A conduit is fixedly connected to the air extraction end of the air extraction machine, and one end of the conduit is connected to the air extraction chamber.

[0011] Furthermore, the chassis has mounting slots on both sides of the slot, and a first support plate is slidably arranged in the mounting slot. An elastic block is fixedly connected to the bottom of the first support plate, and the bottom of the elastic block is fixedly connected to the bottom wall of the mounting slot. The rotating shaft of the fixed roller is fixedly installed in the first support plate.

[0012] Furthermore, a square groove is provided in the fixed base, and limiting grooves communicating with it are provided on both sides of the square groove in the fixed base.

This can effectively adapt to the warping and uneven thickness of the backing paper, significantly increase the effective contact area between the bristles and the surface of the backing paper, solve the problem of cleaning dead corners in fixed brushes, and thus achieve thorough removal of dust from the bottom of the backing paper.

[0015] 2. In this dust collection device after the label backing paper is dried, by combining reciprocating brushing with a negative pressure suction system, the dust can be sucked in and discharged the instant the brush brushes sweep the dust away from the backing paper, avoiding secondary dust and dust accumulation inside the device, and ensuring continuous and efficient cleaning capabilities.

[0016] 3. In this dust collection device after drying the label backing paper, a pressure roller with adjustable height and a fixed roller with elastic buffer work together to flatten the backing paper immediately after dust removal. This structure can not only precisely control the flattening force to adapt to backing papers of different thicknesses and effectively eliminate curling that may be caused by drying and dust brushing, but also avoid damaging the backing paper due to excessive pressure, thus ensuring the appearance quality of the product and the smooth progress of subsequent processing.

Detailed Implementation

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] This embodiment provides a dust collection device for dried label backing paper, including a housing 1. The housing 1 has a slot 11. The dried backing paper passes horizontally over the slot 11. A dust brush 2 is slidably disposed in the slot 11. The dust brush 2 includes at least a fixed plate 21 slidably disposed in the slot 11. A connecting plate 22 is slidably disposed on the fixed plate 21. Dense bristles 221 are fixedly connected to the connecting plate 22. The bristles 221 are used to brush away dust adhering to the bottom of the backing paper. A fixed roller 3 is slidably disposed in the slot 11 near the end of the backing paper's forward direction. Two fixed seats 5 are symmetrically fixed on the housing 1. A pressure roller 4 for flattening the backing paper is slidably disposed between the two fixed seats 5. The pressure roller 4 is located directly above the fixed roller 3. The backing paper passes between the fixed roller 3 and the pressure roller 4.

[0021] like Figure 3 As shown, the upper ends of both the fixing plate 21 and the connecting plate 22 are arc-shaped. The fixing plate 21 has a groove 211, and the connecting plate 22 is slidably installed in the groove 211. The fixing plate 21 has symmetrical connecting grooves 212 on both sides that communicate with the groove 211. The dust brushed off can be guided through the arc surface of the connecting groove 212 to the area below the groove 11, thus avoiding accumulation in the groove 211.

[0022] like Figure 3 As shown, connecting rods 222 are fixedly connected to both ends of the connecting plate 22. The connecting rods 222 are slidably disposed in the groove 213. Several springs 23 are symmetrically fixedly disposed in the groove 211. One end of the spring 23 is fixedly connected to the inner wall of the groove 211, and the other end is fixedly connected to the side wall of the connecting plate 22. Therefore, the connecting plate 22 can shake to a certain extent in the fixed plate 21. Since the backing paper may have local warping, wavy edges or uneven thickness after drying, the bristles 221 form a "flexible contact surface" under the action of the springs 23, which can better fit the surface of the backing paper and improve the cleaning rate. At the same time, its shaking also helps to brush off the dust.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the housing 1 has long slots 14 on both sides of the slot 11, which are connected to the slots. A lead screw 15 is rotatably installed in the long slot 14. The two ends of the fixed plate 21 are fixedly connected to sliders 24. The sliders 24 are slidably installed in the long slot 14, and the lead screw 15 passes through the sliders 24 and is threadedly connected to them. A micro motor is embedded in the housing 1. The output shaft of the micro motor is fixedly connected to the lead screw 15, thereby driving the lead screw 15 to rotate, thereby driving the slider 24 to slide along the long slot 14, and thus driving the dust brush component 2 to move back and forth on the bottom of the bottom paper.

[0024] like Figure 1 and Figure 2 As shown, in order to remove the dust brushed off in a timely manner, a mounting plate 12 is fixedly installed below the slot 11, and several through holes 121 are opened through the mounting plate 12. An air extraction chamber 13 is opened inside the housing 1 below the mounting plate 12. An air extraction machine 6 is fixedly installed on the outside of the housing 1. A conduit 61 is fixedly connected to the air extraction end of the air extraction machine 6. One end of the conduit 61 is connected to the air extraction chamber 13. When the air extraction machine 6 is started, a negative pressure is formed in the air extraction chamber 13. This negative pressure acts on the area of ​​the slot 11 through the through holes 121, thereby quickly sucking away the dust swept off by the dust brush component 2 and discharging it through the conduit 61, effectively preventing the dust from being re-entrained.

[0025] like Figure 4 and Figure 5 As shown, the housing 1 has mounting slots on both sides of the slot 11. A first support plate 16 is slidably arranged in the mounting slot. An elastic block 17 is fixedly connected to the bottom of the first support plate 16, and the bottom of the elastic block 17 is fixedly connected to the bottom wall of the mounting slot. The rotation shaft of the fixed roller 3 is fixedly installed in the first support plate 16. The setting of the elastic block 17 allows the fixed roller 3 to move up and down slightly by means of the compression of the elastic block 17 when it is subjected to pressure from above, thus playing a buffering role.

[0026] like Figure 4 and Figure 5 As shown, a square groove 51 is provided in the fixed base 5, and limiting grooves 52 communicating with it are provided on both sides of the square groove 51 in the fixed base 5. A second support plate 53 is slidably installed in the square groove 51, and limiting blocks 531 are fixedly connected to both sides of the second support plate 53. The limiting blocks 531 are slidably installed in the limiting groove 52.

[0027] like Figure 4 and Figure 5 As shown, the rotating shaft of the pressure roller 4 is rotatably installed in the second support plate 53. Two limiting grooves 52 are threadedly installed on the fixed seat 5, and the screws 54 pass through the limiting block 531 and are threadedly connected to it. By rotating the screws 54 on both sides, the second support plate 53 and the pressure roller 4 can be driven to rise and fall as a whole, thereby accurately setting the distance between the pressure roller 4 and the lower fixed roller 3. The distance is slightly smaller than the thickness of the bottom paper to achieve effective flattening without damaging the material. A motor 7 is fixedly connected to the side wall of one of the second support plates 53. The output shaft of the motor 7 is fixedly connected to the pressure roller 4 to drive the pressure roller 4 to rotate, assisting in traction and flattening of the bottom paper.

[0028] In practical use, the dried label backing paper is guided to the slot 11 above the machine housing 1, allowing it to enter smoothly along the conveying direction. Based on the thickness of the backing paper used in production, the height of the second support plate 53 is adjusted by rotating the screw 54 on the fixed base 5, thereby precisely setting the distance between the pressure roller 4 and the lower fixed roller 3. A negative pressure is created in the suction chamber 13 by the vacuum pump 6, which is transmitted to the slot 11 area through the through hole 121 on the mounting plate 12, creating a downward suction force. The lead screw 15 is driven to rotate by a micro motor, causing the slider 24 to reciprocate within the long slot 14, thus pushing the entire dust-dispensing component 2 to move laterally reciprocally below the backing paper. The motor 7 is then activated. The pressure roller 4 rotates; as the dust brushing component 2 moves back and forth, the bristles 221 on it continuously contact and brush the bottom surface of the backing paper, sweeping off the attached dust, debris and other impurities; the dust brushed off is quickly sucked into the suction chamber 13 through the through hole 121 and discharged through the conduit 61; during this process, the spring 23 causes the connecting plate 22 and the bristles 221 to shake slightly; after passing through the dust brushing area, the backing paper immediately enters between the fixed roller 3 and the pressure roller 4. The pressure roller 4 rotates under the drive of the motor 7 and works together with the fixed roller 3 below to clamp and flatten the backing paper; the elastic block 17 under the first support plate 16 can provide cushioning, allowing the fixed roller 3 to finely adjust the height according to the thickness of the backing paper, ensuring moderate pressure and avoiding damage to the backing paper.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
