Description

Technical Field

[0001] The invention belongs to the field of membrane dust removal, and in particular relates to a dust removal device for a PVC membrane. Background Art

[0002] The main component of PVC is polyvinyl chloride, which is slightly yellow and translucent, glossy, more transparent than polyethylene and polypropylene, but less transparent than polystyrene. The essence of PVC is a vacuum blister film, which is used for surface packaging of various panels, so it is also called decorative film or adhesive film. It is widely used in many industries such as building materials, packaging, and medicine.

[0003] When producing PVC film, the last process is winding. The PVC film needs to be rolled up for storage. However, during the processing of the PVC film, static electricity will exist on its surface, which will absorb dust in the air. When the dust is rolled up in the PVC film, after long-term storage, the dust will push up the PVC film to form a small white spot, causing the quality of the PVC film to deteriorate. Therefore, before the PVC film is rolled up, a dust removal device is usually used to remove dust from the PVC film.

[0004] In response to the above-mentioned technical problems, the applicant has retrieved some prior arts, such as a Chinese patent with patent publication number CN206838674U for dust removal equipment for food packaging film processing, which connects a lower dust-removing roller and an upper dust-removing roller to a lower dust-removing roller and an upper dust-removing roller respectively, and provides replaceable sticky paper layers on the lower dust-removing roller and the upper dust-removing roller. The packaging film passes through the lower dust-removing roller and the upper dust-removing roller, and the dust on the front or back of the packaging film can be sucked away by the lower dust-removing roller and the upper dust-removing roller, and transferred to the sticky paper layers on the lower dust-removing roller and the upper dust-removing roller respectively, thereby improving the dust removal efficiency and dust removal quality of the food packaging film.

[0005] However, the area of ​​the sticky paper layer is limited. When there is a lot of dust on the packaging film, the sticky paper layer needs to be replaced frequently to ensure the stickiness of the sticky roller so that the dust on the dust removal roller can be removed in time. Frequent replacement of the sticky paper layer requires shutdown of the machine, which will greatly affect the dust removal efficiency of the packaging film. In addition, the dust on the packaging film is unevenly distributed. The same position on the dust removal roller may be sticky with a lot of dust, while other positions are less sticky. When the sticky roller sticks dust to the sticky paper layer, the position with more dust may be covered with the sticky paper layer first, while other positions are not covered with dust. If the sticky paper layer is replaced at this time, it will cause a waste of the sticky paper layer. If it is not replaced, the sticky paper layer will no longer be able to stick to the dust on the dust removal roller, and the dust removal roller will not be able to remove the dust on the packaging film, resulting in a decrease in the dust removal effect.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0029] like Figure 1-Figure 7 As shown, a dust removal device for a PVC film provided by the present invention comprises a mounting frame 1, on which a dust sticking component 2 and a dust collecting component 3 are mounted, the output end of the dust sticking component 2 is in contact with the film body 10, the dust sticking component 2 is used to stick the dust on the film body 10, the output end of the dust collecting component 3 is in contact with the output end of the dust sticking component 2, the dust collecting component 3 is used to stick the dust on the dust sticking component 2, and the viscosity of the output end of the dust collecting component 3 is greater than the viscosity of the output end of the dust sticking component 2; The mounting frame 1 is also provided with a flushing assembly 4, the output end of which is located above the output end of the dust collecting assembly 3. The flushing assembly 4 is used to flush the output end of the dust collecting assembly 3 and flush away the dust on the output end of the dust collecting assembly 3, so that the dust collecting assembly 3 can be used all the time without replacement, thereby improving work efficiency and dust removal effect; A dehumidification mechanism 5 is also installed on the mounting frame 1, and the output end of the dehumidification mechanism 5 is in contact with the output end of the dust collecting component 3. The output end of the dehumidification mechanism 5 is located on the side of the output end of the flushing component 4 along the rotation direction of the dust collecting component 3. The dehumidification mechanism 5 is used to absorb moisture on the surface of the output end of the dust collecting component 3 and drive the output end of the dust collecting component 3 to rotate, so as to avoid the reduction of viscosity of the output end of the dust collecting component 3.

[0030] like Figure 1-Figure 3 and Figure 6 As shown, a dust removal device for PVC film provided by the present invention, in this embodiment, the dust sticking component 2 includes two first sliding mounting blocks 23 slidably mounted on the mounting frame 1, a dust sticking rubber roller 21 is rotatably mounted between the two first sliding mounting blocks 23, a first cylinder 22 is fixedly mounted on the mounting frame 1, and the movable end of the first cylinder 22 is fixedly connected to the first sliding mounting block 23.

[0031] The first air cylinder 22 is used to control the position of the sticky rubber roller 21. When not in use, the first air cylinder 22 can drive the sticky rubber roller 21 to retract into the mounting frame 1, so that the sticky rubber roller 21 and the membrane body 10 are separated to protect the sticky rubber roller 21 and extend the service life of the sticky rubber roller 21.

[0032] like Figure 1-Figure 3 and Figure 6 As shown, a dust removal device for PVC film provided by the present invention, in this embodiment, the dust collecting component 3 includes a sliding frame 32 slidably mounted on the mounting frame 1, a dust collecting rubber roller 31 is rotatably mounted on the sliding frame 32, a second cylinder 33 is fixedly mounted inside the mounting frame 1, and a movable end of the second cylinder 33 is fixedly connected to the sliding frame 32, the dust collecting rubber roller 31 can contact with the dust sticking rubber roller 21, and the viscosity of the dust collecting rubber roller 31 is greater than that of the dust sticking rubber roller 21; The surfaces of the dust collecting rubber roller 31 and the dust sticking rubber roller 21 can be made of silicone material, and the hardness of the silicone material on the dust collecting rubber roller 31 is greater than the hardness of the silicone material on the dust sticking rubber roller 21 .

[0033] This is because, in general, as the hardness of silicone increases, its internal cross-linking density may also increase, which will lead to increased friction between molecular chains and thus increase the viscosity of silicone.

[0034] Silicone is waterproof. Even if it is washed with water, the viscosity of silicone will not disappear, but will be slightly reduced. However, when the moisture on the silicone is removed, the silicone will regain its viscosity.

[0035] When in use, the dust collecting rubber roller 31 is brought into contact with the dust sticking rubber roller 21, so that the dust collecting rubber roller 31 can stick the dust on the dust sticking rubber roller 21. When not in use, the second cylinder 33 drives the sliding frame 32 and the dust collecting rubber roller 31 to retreat, so that the dust collecting rubber roller 31 and the dust sticking rubber roller 21 are separated, so as to protect the dust sticking rubber roller 21 and the dust collecting rubber roller 31.

[0036] like Figure 1-Figure 3 and Figure 6 As shown, a dust removal device for PVC film provided by the present invention, in this embodiment, the flushing component 4 includes a water tank 47 fixedly installed inside the mounting frame 1, a water pump 44 is fixedly installed on the water tank 47, the water inlet of the water pump 44 is connected to the inside of the water tank 47 through a water inlet pipe, the water outlet of the water pump 44 is connected to a water outlet pipe 41, one end of the water outlet pipe 41 is connected to a spray pipe 43, the mounting frame 1 is fixedly connected to a first cross plate 42, the spray pipe 43 is fixedly installed on the first cross plate 42, the spray pipe 43 is connected to a plurality of spray heads 48 facing the side of the dust collecting rubber roller 31, the bottom of the spray head 48 is higher than the top of the dust collecting rubber roller 31, so as to avoid the spray head 48 affecting the movement of the dust collecting rubber roller 31; In order to avoid wasting water on the dust collecting rubber roller 31 and reduce the amount of water on the surface of the dust collecting rubber roller 31, the flushing component 4 also includes a water collecting trough 46, which is fixedly connected to the sliding frame 32. The cross-section of the water collecting trough 46 is arc-shaped. One end of the water collecting trough 46 close to the dust collecting rubber roller 31 is fixedly connected with a waterproof rubber strip 49. The waterproof rubber strip 49 is interference fit with the dust collecting rubber roller 31. The bottom of the water collecting trough 46 is connected to multiple return pipes 45, and one end of the multiple return pipes 45 is connected to the water tank 47.

[0037] The water pump 44 draws water from the water tank 47 and sprays it onto the dust collecting rubber roller 31 from the spray head 48 through the water outlet pipe 41 and the spray main pipe 43. The water flowing down from the dust collecting rubber roller 31 flows into the water collecting tank 46, and the water flows back to the knocking mechanism 7 through the return pipe 45, so that the water in the water tank 47 forms a circulation to avoid water waste.

[0038] The water in the water tank 47 can be replaced regularly to avoid excessive dust in the water, which causes the dust contained in the water sprayed from the spray head 48 to be contaminated again on the dust collecting rubber roller 31, thereby preventing the dust removal effect of the device from being reduced; A filter screen may also be provided in the water tank 47 to filter the return water from the return pipe 45, and the water inlet pipe may be extended below the filter screen to prevent the water inlet pipe from drawing in water containing dust.

[0039] like Figure 1-Figure 4 and Figure 6-Figure 7As shown, a dust removal device for a PVC film provided by the present invention, in this embodiment, the dehumidification mechanism 5 includes two groups of third sliding mounting blocks 58, the two groups of the third sliding mounting blocks 58 are slidably mounted on the mounting frame 1, a second compression spring 59 is connected between the third sliding mounting blocks 58 and the mounting frame 1, each group of the third sliding mounting blocks 58 includes two third sliding mounting blocks 58, the two third sliding mounting blocks 58 are respectively slidably mounted on both sides of the mounting frame 1, and a first driven spring is rotatably mounted between the two groups of the third sliding mounting blocks 58. Roller 51 and second driven roller 52, two second sliding mounting blocks 56 are slidably mounted on the mounting frame 1, a tensioning roller 55 is rotatably mounted between the two second sliding mounting blocks 56, a first compression spring 57 is connected between the second sliding mounting block 56 and the mounting frame 1, a driving roller 54 is also rotatably mounted on the mounting frame 1, a water-absorbing cloth 53 is transmission-connected between the first driven roller 51, the second driven roller 52, the tensioning roller 55 and the driving roller 54, and the first driven roller 51 and the second driven roller 52 are tangent to the dust collecting rubber roller 31 through the water-absorbing cloth 53; The absorbent cloth 53 is made of a material that is highly absorbent and easy to dry, such as cotton cloth, Tencel fiber, etc.; The dehumidification mechanism 5 further includes a motor 511 fixedly mounted on the mounting frame 1 , and a first transmission pair 510 is transmission-connected between the output shaft of the motor 511 and one end of the driving roller 54 .

[0040] The motor 511 drives the driving roller 54 to rotate through the first transmission pair 510, and the driving roller 54 drives the water-absorbing cloth 53 to rotate. The water-absorbing cloth 53 in contact with the dust collecting rubber roller 31 absorbs the moisture on the surface of the dust collecting rubber roller 31; At the same time, the absorbent cloth 53 will also drive the dust collecting rubber roller 31 to rotate, and the dust collecting rubber roller 31 will drive the dust sticking rubber roller 21 to rotate, so that the dust sticking rubber roller 21 and the membrane body 10 keep moving at the same speed, and the dust sticking rubber roller 21 can stick the dust on the membrane body 10. Compared with the technical solution in the prior art that uses the membrane body 10 to drive the dust sticking rubber roller 21 to rotate, the reaction force of this mechanism on the membrane body 10 is smaller, thereby preventing the membrane body 10 from being deformed.

[0041] When not in use, the second cylinder 33 drives the dust collecting rubber roller 31 to retreat, and the dust collecting rubber roller 31 will pass over the second driven roller 52 and retreat to one side of the dehumidification mechanism 5. Under the action of the second compression spring 59, the second driven roller 52 will not affect the movement of the dust collecting rubber roller 31. After the dust collecting rubber roller 31 passes over the second driven roller 52, the second compression spring 59 will push the third sliding mounting block 58 and the second driven roller 52 to rise, and the first compression spring 57 will also drive the tensioning roller 55 to move outward through the second sliding mounting block 56 to tighten the absorbent cloth 53 to avoid dislocation of the absorbent cloth 53. When used again, the dust collecting rubber roller 31 can also pass over the second driven roller 52 and move between the second driven roller 52 and the first driven roller 51, so that the absorbent cloth 53 is close to the dust collecting rubber roller 31 again.

[0042] like Figure 2-Figure 4 and Figure 6 As shown, a dust removal device for PVC film provided by the present invention is provided. In order to enable the absorbent cloth 53 to dry quickly so as to be recycled, in this embodiment, a drying component 6 is also installed inside the mounting frame 1. The drying component 6 includes a heating box 62. The heating box 62 is fixedly installed on the mounting frame 1. The absorbent cloth 53 is located inside the heating box 62. Heating plates 61 are installed on both sides of the heating box 62 close to the absorbent cloth 53.

[0043] When the absorbent cloth 53 passes through the interior of the drying assembly 6, the power of the heating plate 61 is turned on, and the heating plate 61 can quickly dry the absorbent cloth 53 to facilitate its next water absorption. The device can work continuously and avoid the water absorption of the absorbent cloth 53 decreasing, resulting in incomplete absorption of moisture on the surface of the dust collecting rubber roller 31, which in turn reduces the viscosity of the dust collecting rubber roller 31 and causes a decrease in the dust removal effect.

[0044] like Figure 1-Figure 7As shown, a dust removal device for PVC film provided by the present invention is provided. When the device works continuously for a long time, a large amount of dust will accumulate in the water tank 47, turning the clean water into sewage. Inevitably, sewage will be sprayed out from the spray head 48, and the dust contained in the sewage may be contaminated on the dust collecting rubber roller 31. When the absorbent cloth 53 absorbs the sewage on the surface of the dust collecting rubber roller 31, the absorbent cloth 53 will absorb the dust together. When the drying component 6 dries the absorbent cloth 53, the dust will accumulate on the surface of the absorbent cloth 53. When the absorbent cloth 53 encounters the dust collecting rubber roller 31 again and absorbs the water on the surface of the dust collecting rubber roller 31, the dust on the absorbent cloth 53 may also be contaminated on the dust collecting rubber roller 31, thereby reducing the dust removal effect. In this embodiment, a knocking mechanism 7 is further installed inside the mounting frame 1. The knocking mechanism 7 includes a second horizontal plate 73 fixedly connected to the inside of the mounting frame 1. The second horizontal plate 73 is located at the absorbent cloth 53. The second cross plate 73 is provided with a plurality of striking assemblies, and the striking assemblies include a rotating shaft 74 rotatably mounted on the second cross plate 73, one end of the rotating shaft 74 is fixedly connected to a fixed platform 76, a rotating ring 75 is rotatably mounted on the fixed platform 76, an arm 77 is fixedly connected to the side of the rotating ring 75, and a striking hammer 78 is fixedly connected to the end of the arm 77. A mounting groove 711 is provided on the side of the fixed platform 76 located inside the rotating ring 75, a wedge block 713 is slidably mounted inside the mounting groove 711, a third compression spring 712 is connected between the wedge block 713 and the mounting groove 711, an end of the wedge block 713 extending out of the mounting groove 711 is provided with an inclined surface, an annular groove 710 is provided inside the rotating ring 75 for the wedge block 713 to move, and a limiting ball head 714 adapted to the wedge block 713 is fixedly connected to the side wall of the annular groove 710; In order to make the multiple striking assemblies move, the multiple rotating shafts 74 are connected to each other by a third transmission pair 79, and a linkage mechanism is connected between one rotating shaft 74 and the driving roller 54. The driving roller 54 drives one rotating shaft 74 to rotate through the linkage mechanism, and the rotating shaft 74 drives all the rotating shafts 74 to rotate through the third transmission pair 79. A dust box 8 is inserted into the mounting frame 1 , and the dust box 8 is located below the tensioning roller 55 and the driving roller 54 .

[0045] The rotating shaft 74 drives the fixed platform 76 and the wedge block 713 to rotate, and the wedge block 713 drives the rotating ring 75 to move through the limiting ball head 714. The rotating ring 75 drives the knocking hammer 78 to rotate through the arm rod 77. When the knocking hammer 78 is blocked by the side of the absorbent cloth 53, the limiting ball head 714 will reversely squeeze the wedge block 713 to retract the wedge block 713 into the installation groove 711. When the wedge block 713 passes over the limiting ball head 714, the absorbent cloth 53 is elastic under the elasticity of the first compression spring 57. The hammer 78 is given a reverse force, so that the hammer 78 moves in the reverse direction quickly. The hammer 78 drives the rotating ring 75 to rotate in the reverse direction through the arm 77. When the limiting ball head 714 encounters the wedge block 713 again, the limiting ball head 714 squeezes the wedge block 713 under the action of inertia, and squeezes the wedge block 713 into the installation groove 711 for a distance. When the limiting ball head 714 and the wedge block 713 reach a balanced state, the fixing platform 76 passes through the wedge block 713. The limiting ball head 714 and the rotating ring 75 are driven to move together. At the same time, under the elastic force of the third compression spring 712, the wedge block 713 will give a thrust to the limiting ball head 714, so that the limiting ball head 714 drives the rotating ring 75 and the knocking hammer 78 to quickly hit the water-absorbing cloth 53. Since the rotation speed of the rotating ring 75 is greater than the rotation speed of the fixed platform 76, the knocking hammer 78 will hit the water-absorbing cloth 53 first. Since the wedge block 713 is not in contact with the limiting ball head 714 at this time, the water-absorbing cloth 53 The knocking hammer 78 will rebound again, so that the knocking hammer 78 drives the limiting ball head 714 to hit the wedge block 713 again. Under the action of the fixed platform 76 and the third compression spring 712, the knocking hammer 78 hits the absorbent cloth 53 again. When the fixed platform 76 does not squeeze the knocking hammer 78 onto the absorbent cloth 53, the knocking hammer 78 will repeat the above process until the knocking hammer 78 contacts the absorbent cloth 53 and the wedge block 713 passes over the limiting ball head 714, and then the next impact cycle will be started; In one knocking operation cycle of this mechanism, the knocking hammer 78 will strike the absorbent cloth 53 multiple times, thereby improving the dust removal effect; Due to the friction between the fixed platform 76 and the rotating ring 75 , the kinetic energy of the rotating ring 75 will gradually decrease. When the limiting ball head 714 encounters the wedge block 713 again, the limiting ball head 714 will not go over the wedge block 713 .

[0046] like Figure 4 and Figure 7 As shown, a dust removal device for PVC film provided by the present invention, in this embodiment, the linkage mechanism includes a rotating rod 72 rotatably mounted on the mounting frame 1, a second transmission pair 71 is transmission-connected between the rotating rod 72 and a rotating shaft 74, and a fourth transmission pair 715 is connected between one end of the rotating rod 72 extending out of the mounting frame 1 and one end of the driving roller 54.

[0047] like Figure 5As shown, a dust removal device for PVC film provided by the present invention is provided. In order to improve the dust removal effect, in this embodiment, a cleaning brush 9 is provided on the side of the heating box 62, and one end of the cleaning brush 9 is in contact with the surface of the absorbent cloth 53.

[0048] When the knocking mechanism 7 knocks the dust on the absorbent cloth 53 to loosen it, but the dust does not fall off, the cleaning brush 9 will brush the dust off the surface of the absorbent cloth 53.

[0049] like Figure 8 As shown, a dust removal device for PVC film provided by the present invention is provided. During the use of the device, some companies' equipment may not meet the installation environment of the product. Therefore, in the present embodiment, an auxiliary component 11 is provided, and the auxiliary component 11 includes a fixing frame 112. A plurality of transmission rollers 111 are rotatably installed inside the fixing frame 112. The plurality of transmission rollers 111 are distributed in two rows. The film body 10 is passed around the plurality of transmission rollers 111 in a wave shape in sequence, and then the mounting frame 1 is mounted on the side of the fixing frame 112, and the dust-adhesive rubber roller 21 is in contact with the surface of the film body 10. In addition, an electrostatic eliminator may be provided on the fixing frame 112 to eliminate static electricity on the membrane body 10 and make it easier for dust on the membrane body 10 to fall off.

[0050] Working principle: The mounting frame 1 is mounted on the equipment equipped with the membrane body 10, or the membrane body 10 passes through the auxiliary component 11, and the mounting frame 1 is mounted on the auxiliary component 11. The first cylinder 22 drives the first sliding mounting block 23 and the dust-sticking rubber roller 21 to move, so that the dust-sticking rubber roller 21 contacts the surface of the membrane body 10, and then the second cylinder 33 drives the sliding frame 32 and the dust-collecting rubber roller 31 to move, so that the dust-collecting rubber roller 31 contacts the surface of the dust-sticking rubber roller 21; The motor 511, the water pump 44 and the heating plate 61 are started, and the membrane body 10 is moved at the same time. The motor 511 drives the driving roller 54 to rotate through the first transmission pair 510, and the driving roller 54 drives the water-absorbing cloth 53 to circulate, and the water-absorbing cloth 53 drives the dust-collecting rubber roller 31 to rotate, and the dust-collecting rubber roller 31 drives the dust-sticking rubber roller 21 to rotate, so that the dust-sticking rubber roller 21 and the membrane body 10 rotate synchronously in opposite directions, and the dust-sticking rubber roller 21 sticks the dust on the membrane body 10; At the same time, the water pump 44 draws water from the water tank 47 and sprays it onto the dust collecting rubber roller 31 to wash away the water on the surface of the dust collecting rubber roller 31; The absorbent cloth 53 also absorbs water on the surface of the dust collecting rubber roller 31 to prevent the viscosity of the surface of the dust collecting rubber roller 31 from decreasing; When the wet absorbent cloth 53 passes through the drying assembly 6, the heating plate 61 will dry the absorbent cloth 53, so that the absorbent cloth 53 can absorb the water on the surface of the dust collecting rubber roller 31 again; At the same time, the driving roller 54 drives the rotating rod 72 to rotate through the fourth transmission pair 715, and the rotating rod 72 drives a rotating shaft 74 to rotate through the second transmission pair 71. The rotating shaft 74 drives all the rotating shafts 74 to rotate through the third transmission pair 79. The rotating shaft 74 drives the knocking hammer 78 to perform multiple impacts on the surface of the absorbent cloth 53, knocking off the dust on the surface of the absorbent cloth 53. The dust will fall into the dust collecting box 8, preventing the dust on the absorbent cloth 53 from sticking to the surface of the dust collecting rubber roller 31 again, thereby preventing the dust removal effect of the device from being reduced.
