Description

Technical Field

[0001] The invention relates to the technical field of sound insulation cotton assembly, and in particular to a glue purification device for automobile sound insulation cotton coating. Background Art

[0002] Car sound insulation cotton gluing is the process of using specific glue to stick it to the corresponding parts of the vehicle (such as the hood, door, roof and trunk, etc.) during the installation of the car sound insulation cotton. In the current gluing process, the specific operation is to first apply the glue on the gluing roller, and then apply a certain pressure to the sound insulation cotton through the gluing roller to achieve uniform application of the glue on the sound insulation cotton. However, after the glue roller has finished gluing the sound insulation cotton, a layer of glue will remain on its surface, and impurities on the sound insulation cotton are easily adhered to this layer of glue. As the glue roller continues to rotate, these impurities will be brought into the glue chamber, thereby contaminating the originally clean glue in the chamber. Therefore, the prior art generally equips a scraper to scrape off the glue with impurities after the glue roller has finished gluing. At this time, the glue purification device comes into play, aiming to purify the glue containing impurities so that it can be recycled and reused; Existing glue purification devices generally rely on filters to intercept impurities in the glue. During operation, the glue to be purified is poured into a purification cylinder equipped with a filter. However, in this process, the "rope reel effect" phenomenon often occurs: that is, when the glue falls onto the surface of the filter, it tends to form a stacked and curled state rather than being evenly spread out. This phenomenon not only hinders the uniform distribution of glue on the filter and reduces the overall filtration efficiency, but also further leads to the concentration of impurities in local areas. The originally dispersed and fine impurities will gather together under the action of the "rope reel effect" to form larger impurity clumps. These clumps are more likely to clog the pores of the filter, thereby aggravating the obstacles in the purification process. Based on this, the present invention purposely provides a glue purification device for automobile sound insulation cotton coating glue that can improve purification efficiency and purification effect. Summary of the invention

[0003] The purpose of the present invention is to provide a glue purification device for automobile sound insulation cotton coating to solve the technical problems in the prior art in view of the shortcomings of the prior art.

The top of the rotating barrel is open, and the discharge end of the storage barrel faces the top of the rotating barrel. An opening is opened at the bottom of the rotating barrel, and the opening faces the purification barrel. The opening is radially arranged along the bottom of the rotating barrel.

A baffle is slidably installed on the fixed frame, the baffle blocks the opening, and a discharge port is opened on the fixed frame. The discharge port is connected with the rotating drum through the opening. When the first output source drives the rotating drum to rotate, the rotating drum rotates through the driving assembly to drive the baffle to reciprocate along the opening direction.

[0005] As a further solution of the present invention: the driving assembly includes a reciprocating screw, a slider, a transmission gear, an outer gear ring and a linkage assembly. A fixed box is fixedly installed on the fixed frame, and the linkage assembly is arranged in the fixed box.

It is fixedly connected to the baffle and threadedly connected to the reciprocating screw. The outer gear ring is fixedly installed on the bearing plate, which is sleeved on the outer cylindrical surface of the rotating drum, and there is a gap between the two. The transmission gear is rotatably installed on the fixed box and meshes with the outer gear ring. When the transmission gear rotates, it drives the reciprocating screw to rotate through the linkage assembly.

[0006] As a further solution of the present invention: the linkage assembly includes a first bevel gear and a second bevel gear, the first bevel gear and the second bevel gear are both rotatably installed in a fixed box, the axes of the two are perpendicular to each other, and the two are meshed, the first bevel gear is coaxially fixedly connected to the transmission gear, and the second bevel gear is coaxially fixedly connected to the reciprocating screw.

[0007] As a further solution of the present invention: a fixed seat is fixedly installed on the baffle, a lifting rod is arranged on the fixed seat, a conical cone is fixedly installed on the lifting rod, the radius of the conical cone increases downward along its axial direction, the axis of the conical cone coincides with the axis of the discharge port, and a plurality of guide grooves are arranged on the circumference of the conical cone.

[0008] As a further solution of the present invention: the lifting rod is slidably installed on the fixed seat, and is driven to rise and fall by a driving source built into the fixed seat. A ranging component is provided at the bottom end of the fixed seat, and the ranging component is connected to the driving source.

[0009] As a further solution of the present invention: an opening and closing plate is rotatably installed in the fixed seat, the opening and closing plate is driven to rotate by the second output source, and the opening and closing plate is used to control the opening and closing of the discharge port.

[0010] As a further solution of the present invention: a stirring member is fixedly mounted on the top plate of the bracket, and the stirring member extends into the rotating drum.

[0011] As a further solution of the present invention: the outer cylindrical surface of the storage barrel is provided with a first insulation component, the first insulation component is used to heat the glue in the storage barrel, and the outer cylindrical surface of the purification barrel is provided with a second insulation component, the second insulation component is used to heat the glue on the filter plate.

[0012] Beneficial effects of the present invention: 1. In the present invention, the material is discharged when the drum rotates, and the baffle is driven by the driving assembly to reciprocate along the opening direction when the drum rotates. The opening is arranged radially along the bottom of the drum, so the movement of the baffle will cause the discharge port to be eccentrically arranged at the bottom of the drum, so that the landing point of the glue flowing out of the discharge port on the filter plate will change continuously, thereby avoiding the "rope winding effect" when the glue falls, and the position of the discharge port will change continuously along the opening direction, so the landing point of the glue on the filter plate will also show a phenomenon of reciprocating radially along the filter plate. On the one hand, the glue can be evenly spread on the filter plate when it falls, which is conducive to fully utilizing the entire surface of the filter plate for filtration, significantly improving the efficiency of filtration and purification, and on the other hand, it effectively avoids the problem that the glue needs to slowly spread the filter plate due to the fixed landing point, making the distribution of the glue on the filter plate more scientific and reasonable; 2. In the present invention, since the axis of the conical cone coincides with the axis of the discharge port, the glue will fall onto the conical cone after flowing out of the discharge port, and the shape of the conical cone allows the glue to slide down along the inclined surface of the conical cone, thereby spreading the glue gathered together, and the glue will flow into the guide groove when sliding down the inclined surface of the conical cone, causing part of the glue to slide down along the inclined surface of the conical cone, and the other part of the glue to slide down from the guide groove, so that the glue landing points on the filter plate are more dispersed, avoiding glue accumulation, and the glue layer formed at each landing point is relatively thin, which is conducive to the glue passing through the filter plate faster, thereby improving the overall filtration efficiency; 3. In the present invention, when the glue containing impurities falls, the glue will be stretched due to the action of gravity, which will make the impurities originally wrapped in the glue more easily exposed. When more and more glue falls onto the filter plate, the thickness of the glue on the filter plate increases, so that the height of the glue falling from the conical stage will decrease. Therefore, the thickness of the glue on the filter plate is measured by the distance measuring component. When the thickness of the glue exceeds the threshold, the distance measuring component drives the lifting rod to rise through the driving source, so that the conical stage is away from the filter plate, so that the glue falling from the conical stage has a sufficient height, allowing the glue to stretch, so that the impurities inside it are exposed, which is more conducive to subsequent filtration.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-Figure 8 As shown, the present invention is a glue purification device for automobile sound insulation cotton coating, comprising: A bracket 1 is provided with a material storage barrel 2 fixedly mounted thereon, the material storage barrel 2 being used to store glue scraped off from the glue coating roller, a purification barrel 3 fixedly mounted inside the bracket 1, a filter plate 4 fixedly mounted inside the purification barrel 3, a discharge port 5 connected to the bottom of the purification barrel 3, and the top of the purification barrel 3 is open; A carrying plate 6 is fixedly installed in the bracket 1 and is located between the storage barrel 2 and the purification barrel 3. A rotating barrel 7 is rotatably installed on the carrying plate 6. The rotating barrel 7 is driven to rotate by a first output source. The top of the rotating barrel 7 is open, and the discharge end of the storage barrel 2 faces the top of the rotating barrel 7. An opening 8 is opened at the bottom of the rotating barrel 7. The opening 8 faces the purification barrel 3, and the opening 8 is radially arranged along the bottom of the rotating barrel 7. A fixed frame 11 is fixedly installed at the bottom end of the rotating drum 7 and is provided with a driving assembly. A baffle 9 is slidably installed on the fixed frame 11, and the baffle 9 blocks the opening 8. A discharge port 10 is opened on the fixed frame 11, and the discharge port 10 is connected with the rotating drum 7 through the opening 8. When the first output source drives the rotating drum 7 to rotate, the rotating drum 7 rotates and drives the baffle 9 to reciprocate along the direction of the opening 8 through the driving assembly.

[0018] In one case of this embodiment, the first output source can be a motor-driven pulley assembly and a motor-driven gear and ring gear assembly, etc., and other mechanisms that can realize the rotational movement of the drum 7 can also be selected. This embodiment does not make specific limitations here.

[0019] The working principle of the present invention is as follows: first, the scraper is used to scrape the glue roller after the glue coating is completed, and the glue with impurities is scraped off and collected into the storage barrel 2. Then, the glue purification operation can be started, and the glue in the storage barrel 2 is transported to the rotating drum 7 and gathered at the bottom of the rotating drum 7. Then, the glue flows downward into the purification barrel 3 through the opening 8 and the discharge port 10 in turn, and falls onto the filter plate 4. The filter plate 4 will intercept the impurities in the glue. The purified glue will pass through the filter plate 4 and fall to the bottom of the purification barrel 3 and be discharged from the discharge port 5. In this way, the basic filtering and purification operation of the glue containing impurities can be completed; In order to avoid the "rope winding effect" caused by the glue flowing from the discharge port 10 to the filter plate 4, the drum 7 is driven to rotate by the first output source when the drum 7 is discharging, and the baffle 9 is driven by the driving component to reciprocate along the opening 8 when the drum 7 rotates. The opening 8 is arranged radially along the bottom of the drum 7, so the movement of the baffle 9 will cause the discharge port 10 to be eccentrically arranged at the bottom of the drum 7. Because of the rotation of the drum 7, the landing point of the glue flowing out of the discharge port 10 on the filter plate 4 will constantly change, thereby avoiding the "rope winding effect" when the glue falls. ", and the position of the discharge port 10 will continue to change along the direction of the opening 8, so the landing point of the glue on the filter plate 4 will also show a phenomenon of reciprocating movement along the radial direction of the filter plate 4. On the one hand, the glue can be evenly spread on the filter plate 4 when it falls, which is conducive to making full use of the entire surface of the filter plate 4 for filtration, significantly improving the efficiency of filtration and purification. On the other hand, it effectively avoids the problem that the glue needs to slowly spread the filter plate 4 due to the fixed landing point, making the distribution of the glue on the filter plate 4 more scientific and reasonable, and comprehensively improving the effect and quality of the entire filtration and purification process.

[0020] like Figure 1-Figure 4 As shown, as a preferred embodiment of the present invention, the driving assembly includes a reciprocating screw 12, a slider 13, a transmission gear 15, an outer gear ring 16 and a linkage assembly. A fixed box 14 is fixedly installed on the fixed frame 11, and the linkage assembly is arranged in the fixed box 14. The reciprocating screw 12 is rotatably installed in the fixed frame 11, and the slider 13 is slidably installed in the fixed frame 11, which is fixedly connected to the baffle 9 and threadedly connected to the reciprocating screw 12. The outer gear ring 16 is fixedly installed on the bearing plate 6, which is sleeved on the outer cylindrical surface of the rotating drum 7, and there is a gap between the two. The transmission gear 15 is rotatably installed on the fixed box 14, and it is meshed with the outer gear ring 16. When the transmission gear 15 rotates, it drives the reciprocating screw 12 to rotate through the linkage assembly.

[0021] In actual application of this embodiment, when the first output source drives the rotating drum 7 to rotate, the fixed frame 11 and the fixed box 14 at the bottom of the rotating drum 7 will rotate synchronously with the rotating drum 7, so the transmission gear 15 will revolve around the outer ring gear 16, and the transmission gear 15 and the outer ring gear 16 are meshed, so that the transmission gear 15 will rotate on its own, and the rotation of the transmission gear 15 will drive the reciprocating screw 12 to rotate through the linkage assembly, and the rotation of the reciprocating screw 12 will cause the slider 13 to reciprocate, so the slider 13 will drive the baffle 9 to reciprocate on the fixed frame 11, thereby continuously changing the position of the discharge port 10, so that the landing point of the glue on the filter plate 4 is continuously changed, avoiding the occurrence of the "rope winding effect".

[0022] like Figure 5As shown, as a preferred embodiment of the present invention, the linkage assembly includes a first bevel gear 17 and a second bevel gear 18, and the first bevel gear 17 and the second bevel gear 18 are both rotatably installed in the fixed box 14, the axes of the two are perpendicular to each other, and the two are meshed, the first bevel gear 17 is coaxially fixedly connected to the transmission gear 15, and the second bevel gear 18 is coaxially fixedly connected to the reciprocating screw 12.

[0023] In actual application of this embodiment, the rotation of the transmission gear 15 will drive the first bevel gear 17 to rotate, and the first bevel gear 17 is meshed with the second bevel gear 18, thereby driving the second bevel gear 18 to rotate synchronously, and the second bevel gear 18 drives the reciprocating screw rod 12 to rotate, so that the transmission gear 15 drives the reciprocating screw rod 12 to rotate, and the power for the rotation of the transmission gear 15 comes from the rotation of the drum 7, so that the power source is reasonably used, thereby simplifying the power configuration of the entire device.

[0024] like Figure 1-Figure 6 As shown, as a preferred embodiment of the present invention, a fixing seat 19 is fixedly installed on the baffle 9, a lifting rod 20 is arranged on the fixing seat 19, a conical cone 21 is fixedly installed on the lifting rod 20, the radius of the conical cone 21 increases downward along its axial direction, the axis of the conical cone 21 coincides with the axis of the discharge port 10, and a plurality of guide grooves 22 are arranged on the circumference of the conical cone 21.

[0025] In actual application of this embodiment, since the axis of the conical cone 21 coincides with the axis of the discharge port 10, the glue will fall onto the conical cone 21 after flowing out of the discharge port 10, and the shape of the conical cone 21 causes the glue to slide along the inclined surface of the conical cone 21, thereby spreading the gathered glue, and the glue will flow into the guide groove 22 when sliding down the inclined surface of the conical cone 21, causing part of the glue to slide along the inclined surface of the conical cone 21, and the other part of the glue will slide from the guide groove 22, so that the landing points of the glue on the filter plate 4 are more dispersed, avoiding glue accumulation, and the glue layer formed at each landing point is relatively thin, which is conducive to the glue passing through the filter plate 4 faster, thereby improving the overall filtration efficiency.

[0026] like Figure 1-Figure 6 As shown, as a preferred embodiment of the present invention, the lifting rod 20 is slidably installed on the fixed seat 19, and is driven to rise and fall by a driving source built into the fixed seat 19. A distance measuring component 23 is provided at the bottom end of the fixed seat 19. The distance measuring component 23 is connected to the driving source. The distance measuring component 23 is used to measure the thickness of the glue on the filter plate 4. When the glue thickness exceeds the threshold, the distance measuring component 23 drives the lifting rod 20 to rise through the driving source.

[0027] In one case of this embodiment, the driving source may be an electric cylinder, an electric telescopic rod or other components, or other mechanisms capable of realizing lifting and lowering movements. This embodiment is not specifically limited here. It should be noted that the ranging assembly 23 described in the present invention is a prior art, and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.

[0028] In actual application of this embodiment, when the glue containing impurities falls, the glue will be stretched due to the action of gravity, which will make the impurities originally wrapped in the glue more easily exposed. When more and more glue falls on the filter plate 4, the thickness of the glue on the filter plate 4 increases, so that the height of the glue falling from the conical cone 21 will decrease. Therefore, the thickness of the glue on the filter plate 4 is measured by the distance measuring component 23. When the glue thickness exceeds the threshold, the distance measuring component 23 drives the lifting rod 20 to rise through the driving source, so that the conical cone 21 is away from the filter plate 4, so that the glue falling from the conical cone 21 has a sufficient height, allowing the glue to stretch and make its internal impurities appear, which is more conducive to subsequent filtration.

[0029] like Figure 1-Figure 7 As shown, as a preferred embodiment of the present invention, an opening and closing plate 27 is rotatably installed in the fixing seat 19 , and the opening and closing plate 27 is driven to rotate by the second output source. The opening and closing plate 27 is used to control the opening and closing of the discharge port 10 .

[0030] In one case of this embodiment, the second output source may be a servo motor, a servo motor or other components, or other mechanisms capable of achieving rotational motion, which is not specifically limited in this embodiment.

[0031] In actual application of this embodiment, the second output source drives the opening and closing plate 27 to rotate, so that the opening and closing plate 27 can block the discharge port 10 to prevent the glue from flowing out, and move the opening and closing plate 27 away from the discharge port 10, thereby opening the discharge port 10.

[0032] like Figure 1-Figure 8 As shown, as a preferred embodiment of the present invention, a stirring member 26 is fixedly mounted on the top plate of the bracket 1 , and the stirring member 26 extends into the rotating drum 7 .

[0033] In actual application of this embodiment, the stirring member 26 extends into the drum 7, and the first output source drives the drum 7 to rotate. When there is glue in the drum 7, the rotation of the drum 7 will cause the glue to collide with the stirring member 26, thereby playing a stirring role. In this way, impurities can be redistributed evenly in the glue, which is beneficial for the subsequent glue to fall on the filter plate 4 for filtering and purification.

[0034] like Figure 1-Figure 8As shown, as a preferred embodiment of the present invention, the outer cylindrical surface of the storage barrel 2 is provided with a first insulation component 24, and the first insulation component 24 is used to heat the glue in the storage barrel 2. The outer cylindrical surface of the purification barrel 3 is provided with a second insulation component 25, and the second insulation component 25 is used to heat the glue on the filter plate 4.

[0035] In one case of this embodiment, both the first heat-insulating component 24 and the second heat-insulating component 25 can adopt the method of surrounding the electric heating wire and injecting industrial steam into the chamber, etc. This embodiment does not make any specific limitation here.

[0036] In actual application of this embodiment, heating the glue in the storage barrel 2 through the first insulation component 24 can intensify the thermal motion of the glue molecules and increase the distance between the molecules, thereby reducing the viscosity of the glue, making it easier for impurities to move and separate in the glue, and the lower viscosity glue is not easy to produce a "rope winding effect" when falling. Heating the glue on the filter plate 4 through the second insulation component 25 keeps the glue in a low viscosity state, which is conducive to the glue passing through the filter plate 4.

[0037] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
