Description

Technical Field

[0001] The present invention relates to the technical field of material composite processing equipment, and in particular to an activated carbon powder spraying and glue spraying composite machine. Background Art

[0002] An automotive air conditioner filter is a filter used for purifying the air in the vehicle compartment of an automobile. Generally, an activated carbon composite filter cloth is used, which can effectively filter smoke odor, pollen, dust, harmful gases and various odors. While achieving the performance of filtering oil and purifying air, it can also well remove various organic gases. It is an ideal material for the activated carbon powder spraying and glue spraying composite machine used as an automotive air conditioner filter in various high-class automobiles, sedans and commercial vehicles.

[0003] Currently, the manufacturing of the filter element in an automotive air conditioner filter generally is as follows: hot melt adhesive is sprayed on the base material, i.e., non-woven fabric. After spraying the hot melt adhesive, activated carbon powder is then sprayed. Thus, under the adhesion of the glue layer, the activated carbon powder adheres to the non-woven fabric, thereby completing the composition of a single-layer activated carbon composite filter cloth. Finally, two single-layer activated carbon composite filter cloths are pressed together to finally complete the production of the entire activated carbon composite filter cloth; effectively avoiding the problem that the activated carbon powder is prone to accumulate and fall due to the action of gravity, avoiding the uneven distribution of the activated carbon powder, reducing the filtering effect, causing pollution to the air inside the vehicle, and being difficult to ensure the physical health of passengers.

[0004] However, when spraying hot melt adhesive on the non-woven fabric, the sprayed glue liquid is prone to uneven distribution, resulting in a poor adhesion effect of the subsequent glue layer on the activated carbon powder, affecting the distribution effect of the activated carbon powder in the filter cloth and the production of the filter element; at the same time, in the prior art, the effect of using a sponge to adhere to the activated carbon powder and then coating the sponge on the glue layer is poor, which is not conducive to ensuring the uniformity of the powder spraying of the activated carbon powder each time, easily affecting the powder spraying quality of the activated carbon powder and the production of the filter element; and it is impossible to achieve the automatic control effect of the powder spraying operation, increasing the amount of wasted activated carbon powder in actual operation. Summary of the Invention

[0005] The activated carbon powder spraying and glue spraying composite machine proposed by the present invention aims to solve the problem in the traditional technology that the glue liquid sprayed on the non-woven fabric is prone to uneven distribution, resulting in a poor adhesion effect of the subsequent glue layer on the activated carbon powder and affecting the distribution effect of the activated carbon powder in the filter cloth.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] Activated carbon powder spraying and gluing compounding machine, including a frame, on which a plurality of conveying rollers are installed. The base material bypasses the upper sides of the plurality of conveying rollers, and the conveying of the base material is completed under the continuous rotation of the plurality of conveying rollers. A fixed frame is fixedly connected to the frame, and a plurality of injection cylinders are installed on the fixed frame. A glue conveying pipe is connected to the top of each of the plurality of injection cylinders, and the end of the glue conveying pipe away from the injection cylinder is connected to an external glue source. During operation, external glue is input into the plurality of injection cylinders. An injection port is provided at the bottom end of each of the plurality of injection cylinders, and the injection port is directly opposite to the upper surface of the base material. The plurality of injection cylinders output glue onto the base material through the injection ports;

[0008] A lifting assembly is connected to the fixed frame. The lifting assembly is located behind the injection cylinders in the moving direction of the base material. The output end of the lifting assembly is connected to a leveling assembly. The lifting assembly can control the position of the leveling assembly, facilitating the control of the distance between the output end of the leveling assembly and the base material, so as to perform specific operations on base materials with different thicknesses and glue layers of different thicknesses. The leveling assembly includes a connecting shaft, a torsion spring and a scraper. The connecting shaft is rotatably connected to the output end of the lifting assembly. A scraper is fixedly connected to the middle of the connecting shaft. A torsion spring is fixedly connected between the connecting shaft and the output end of the lifting assembly. The bottom plate of the scraper is in clearance fit with the upper surface of the base material. When the base material carries glue and passes by the scraper, the scraper pushes the glue to spread evenly on the base material, achieving the effect of evenly spreading the glue;

[0009] A rotation switch is installed on the fixed frame. The input end of the rotation switch is fixedly connected to the connecting shaft. A powder spreading assembly is connected to the fixed frame. The powder spreading assembly is located behind the lifting assembly in the moving direction of the base material. The powder spreading assembly includes a storage box, a rotation motor, a rotating shaft and a baffle. The storage box is fixedly connected to the fixed frame. Activated carbon powder is stored in the storage box. A strip-shaped opening is provided at the bottom of the storage box. The rotation motor is installed on one side of the storage box. The rotation switch is electrically connected to the rotation motor. The output end of the rotation motor is coaxially fixedly connected to a rotating shaft. A plurality of baffles are fixedly connected to the rotating shaft, and the outer edge of the baffle is matched with the strip-shaped opening.

[0010] Preferably, the plurality of injection cylinders are all distributed along the axial direction of the conveying rollers, and the plurality of injection cylinders are evenly distributed, which is convenient for reducing the subsequent burden of leveling the glue and is beneficial to improving the uniformity of the glue distribution on the base material.

[0011] Preferably, the lifting assembly includes a lifting cylinder and a lifting frame. The lifting cylinder is installed on the fixed frame, and the output end of the lifting cylinder is fixedly connected to the lifting frame. The connecting shaft is rotatably connected to the lifting frame, and the telescopic rod is clamped in the limiting groove, so as to keep the lifting frame moving smoothly and avoid deviation of the lifting frame from affecting the normal operation of the leveling assembly.

[0012] Preferably, both sides of the bottom of the lifting frame are fixedly connected with limiting components. The limiting components include telescopic rods and limiting grooves. The telescopic rod includes a sleeve rod, a straight rod, and a buffer spring. The sleeve rod is fixedly connected to the lifting frame. The straight rod is slidably connected inside the sleeve rod. A buffer spring is fixedly connected between the top end of the straight rod and the inside of the sleeve rod. The limiting groove is opened on the frame, and the bottom end of the straight rod is clamped in the limiting groove.

[0013] Preferably, the bottom of the storage box is cylindrical, with a strip-shaped opening at the bottom of the cylinder. The outer circumferences of multiple baffles are rotationally matched with the inner wall of the cylinder. When the baffles rotate continuously, continuous and stable discharging is completed, improving the uniformity of the spreading of activated carbon powder.

[0014] Preferably, a collection groove is opened on the frame. The collection groove is located below the powder spreading component. A trachea is communicated inside the collection groove. A suction fan is installed at one end of the trachea far from the inside of the collection groove. The output end of the suction fan is communicated with a collection device. When the suction fan works, a suction effect can be formed on the collection groove through the trachea, avoiding the scattered activated carbon powder from escaping into the environment and forming a protective effect on the staff.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting a leveling component in the present invention, after the glue spraying operation on the base material is completed, the scraper pushes the glue to be leveled on the base material, achieving the effect of uniform leveling of the glue, facilitating the subsequent powder spreading operation, and effectively avoiding the problem of product quality decline caused by uneven distribution of the glue.

[0017] 2. By setting a powder spreading component in the present invention, the output end of the rotating motor rotates to drive the rotating shaft to rotate, so that the rotating shaft drives multiple baffles to rotate, and then continuously pushes out part of the activated carbon powder between adjacent baffles, ensuring that uniform activated carbon powder is sprinkled on the leveled glue, improving the powder spreading quality of the activated carbon powder.

[0018] 3. In the present invention, through the slight rotation of the connecting shaft driven by the scraper against the torsion spring under the blockage of the glue, the opening and closing of the rotation switch are controlled in real time, so that the powder spreading component is only started when the leveling component works, forming an automatic control effect on the powder spreading component.

Detailed implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Refer to Figures 1-3 , the activated carbon powder spreading and glue spraying composite machine includes a frame 1, and a plurality of conveyor rollers 2 are installed on the frame 1. Among them, the base material bypasses the upper sides of the plurality of conveyor rollers 2, and the conveying of the base material is completed under the continuous rotation of the plurality of conveyor rollers 2.

[0025] A fixing frame 3 is fixedly connected to the frame 1, and a plurality of injection cylinders 4 are installed on the fixing frame 3. The tops of the plurality of injection cylinders 4 are all communicated with glue delivery pipes 41, and injection ports are arranged at the bottoms of the plurality of injection cylinders 4. Among them, the injection ports are directly opposite to the upper surface of the base material. The glue delivery pipes 41 input external glue into the plurality of injection cylinders 4, and the glue is output to the base material through the plurality of injection cylinders 4.

[0026] The plurality of injection cylinders 4 are all distributed along the axial direction of the conveyor rollers 2, and the plurality of injection cylinders 4 are evenly distributed, which is convenient for reducing the burden of leveling the glue subsequently and is beneficial to improving the uniformity of the glue distribution on the base material.

[0027] A lifting assembly 5 is connected to the fixing frame 3. Among them, the lifting assembly 5 is located behind the injection cylinder 4 in the moving direction of the base material. The output end of the lifting assembly 5 is connected to a leveling assembly 6. The lifting assembly 5 includes a lifting cylinder 51 and a lifting frame 52. The lifting cylinder 51 is installed on the fixing frame 3, and the output end of the lifting cylinder 51 is fixedly connected to the lifting frame 52. The connecting shaft 61 is rotatably connected to the lifting frame 52. When the lifting cylinder 51 works, the output end of the lifting cylinder 51 extends to drive the lifting frame 52 to move downward, and the lifting frame 52 drives the leveling assembly 6 to move downward until the distance between the output end of the leveling assembly 6 and the base material remains a preset distance. Therefore, the position of the leveling assembly 6 can be controlled by the operation of the lifting cylinder 51, which is convenient for specific operations on base materials with different thicknesses and glue layers with different thicknesses.

[0028] Both sides of the bottom of the lifting frame 52 are fixedly connected with limiting components 7. The limiting components 7 include telescopic rods 71 and limiting grooves 72. The telescopic rods 71 include sleeve rods, straight rods and buffer springs. The sleeve rods are fixedly connected to the lifting frame 52. The straight rods are slidably connected inside the sleeve rods. A buffer spring is fixedly connected between the top end of the straight rod and the inside of the sleeve rod. The limiting grooves 72 are opened on the frame 1. The bottom end of the straight rod is clamped in the limiting grooves 72. When the lifting frame 52 moves downward, the telescopic rods 71 are clamped in the limiting grooves 72, so as to keep the movement of the lifting frame 52 stable and avoid deviation of the lifting frame 52 from affecting the normal operation of the scraping component 6.

[0029] The scraping component 6 includes a connecting shaft 61, a torsion spring 62 and a scraping plate 63. The connecting shaft 61 is rotatably connected to the output end of the lifting component 5. A scraping plate 63 is fixedly connected to the middle of the connecting shaft 61. A torsion spring 62 is fixedly connected between the connecting shaft 61 and the output end of the lifting component 5. The bottom plate of the scraping plate 63 is in clearance fit with the upper surface of the base material. When the base material carries the glue through the scraping plate 63, the scraping plate 63 pushes the glue to be paved flat on the base material, completing the uniform paving effect of the glue and facilitating the subsequent powder spreading operation.

[0030] A rotation switch 8 is installed on the fixed frame 3. The input end of the rotation switch 8 is fixedly connected to the connecting shaft 61. A powder spreading component 9 is connected to the fixed frame 3. The powder spreading component 9 is located behind the lifting component 5 in the moving direction of the base material. The powder spreading component 9 includes a storage box 91, a rotation motor 92, a rotation shaft 93 and a baffle 94. The storage box 91 is fixedly connected to the fixed frame 3. Activated carbon powder is stored in the storage box 91. A strip-shaped opening is opened at the bottom of the storage box 91. The rotation motor 92 is installed on one side of the storage box 91. The rotation switch 8 is electrically connected to the rotation motor 92. The scraping plate 63 drives the connecting shaft 61 to rotate slightly against the torsion spring 62 under the block of the glue, thereby turning on the rotation switch 8, forming an automatic control effect on the powder spreading component 9.

[0031] The output end of the rotation motor 92 is coaxially fixedly connected with a rotation shaft 93. A plurality of baffles 94 are fixedly connected to the rotation shaft 93. When the rotation motor 92 works, the output end rotates to drive the rotation shaft 93 to rotate. The rotation shaft 93 drives the plurality of baffles 94 to rotate. Under the rotation of the plurality of baffles 94, part of the activated carbon powder in the space surrounded by the adjacent baffles 94 and the cylindrical inner wall at the bottom of the storage box 91 is pushed out of the storage box 91 and sprinkled on the paved glue, completing the powder spreading operation of the activated carbon powder.

[0032] The outer edge of the baffle 94 is matched with the strip-shaped opening. The bottom of the storage box 91 is arranged in a cylindrical shape. The strip-shaped opening is opened at the bottom of the cylindrical shape. The outer peripheral sides of the plurality of baffles 94 are rotatably matched with the cylindrical inner wall, which is convenient for continuous and stable discharging when the baffles 94 rotate continuously.

[0033] A collection groove 11 is formed on the frame 1. The collection groove 11 is located below the powder spraying assembly 9. A trachea 12 is connected to the inside of the collection groove 11. An air extractor 13 is installed at one end of the trachea 12 away from the inside of the collection groove 11. The output end of the air extractor 13 is connected to a collection device. When the air extractor 13 operates, a suction effect can be formed on the inside of the collection groove 11 through the trachea 12, preventing the spilled activated carbon powder from escaping into the environment.

[0034] During operation, the base material is first conveyed to below the plurality of injection cylinders 4 along the plurality of conveyor rollers 2. The plurality of injection cylinders 4 spray glue onto the base material. Under the continuous conveyance of the plurality of conveyor rollers 2, the base material moves towards the leveling assembly 6 while carrying the glue.

[0035] Start the lifting cylinder 51. The output end of the lifting cylinder 51 extends to drive the lifting frame 52 to move downward. The lifting frame 52 drives the leveling assembly 6 composed of the connecting shaft 61, torsion spring 62, and scraper 63 to move downward until the distance between the scraper 63 and the base material remains a preset distance. When the base material passes through the scraper 63 while carrying the glue, the scraper 63 pushes the glue to spread evenly on the base material, achieving the effect of evenly spreading the glue and facilitating the subsequent powder spraying operation.

[0036] Meanwhile, the scraper 63 overcomes the torsion spring 62 under the obstruction of the glue to drive the connecting shaft 61 to rotate slightly, thereby turning on the rotation switch 8. The rotation switch 8 starts the rotation motor 92 in the powder spraying assembly 9 to operate. The output end of the rotation motor 92 rotates to drive the rotating shaft 93 to rotate. The rotating shaft 93 drives the plurality of baffles 94 to rotate. Under the rotation of the plurality of baffles 94, a part of the activated carbon powder located in the space surrounded by the adjacent baffles 94 and the cylindrical inner wall at the bottom of the storage box 91 is pushed out of the storage box 91 and sprinkled onto the spread glue, completing the powder spraying operation of the activated carbon powder.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
