Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric coating technology, specifically to the adjustment device of a nonwoven fabric coating sample machine. Background Technology

[0002] The nonwoven fabric coating process involves applying a layer of adhesive to create bonding between the fibers, increasing the fabric's toughness and strength, and providing additional functions such as protection, waterproofing, and sound insulation. The adhesive coating sample machine is a crucial piece of equipment in this process.

[0003] Utility model patent CN202321455420.X discloses a nonwoven fabric coating device. This device includes a support frame with a recessed cavity in the middle. A coating roller is housed inside the cavity, and a pressure roller is mounted on top of the coating roller. Fixing devices are installed at both ends of the coating roller. Each fixing device includes a connecting rod fixed to the coating roller and an adjusting rod rotatably mounted on the support frame. A housing is mounted on the end of the adjusting rod furthest from the support frame. A locking mechanism is installed on both the housing and the connecting rod. Guide rollers are installed on both sides of the support frame, and a baffle is located on the top of the support frame. Both ends of the pressure roller are rotatably mounted on the baffle, and a motor is mounted on the baffle of the support frame. The output shaft of the motor is connected to the pressure roller. Through the cooperation of the fixing devices and locking mechanisms, the fixing plate is separated from the housing, allowing the coating roller to be removed from the support frame. This facilitates quick disassembly and cleaning of the coating roller by workers, preventing the coating roller from affecting the coating effect after prolonged use, thereby improving the quality of the nonwoven fabric.

[0004] Although the nonwoven fabric coating device is easy to disassemble and assemble, the device still has the following problems in actual use: the distance between the coating roller and the pressure roller is fixed, so it is difficult to adjust the coating thickness when coating nonwoven fabrics to meet different coating requirements. In view of this, we propose an adjustment device for the nonwoven fabric coating sample machine. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art. To this end, one objective of this utility model is to provide an adjustment device for a nonwoven fabric coating sample machine. By adjusting the height of the pressure roller, the distance between the pressure roller and the coating roller is adjusted, thereby facilitating the coating of nonwoven fabrics with different thicknesses. This design, through the adjustment of the pressure roller height, facilitates the adjustment of the coating thickness of the nonwoven fabric.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The adjustment device of the nonwoven fabric coating sample machine includes a base, a glue tank is fixed at the top rear side of the base, a coating roller is rotatably installed in the top opening of the glue tank, and a first motor for driving the coating roller to rotate is installed at the right end of the glue tank.

[0008] Above the glue-applying roller is a pressure roller assembly, which includes two symmetrical vertical plates fixed to the top of the glue tank. Each vertical plate has a strip groove, and the top of the vertical plate has a sliding groove communicating with the strip groove. Each of the two opposite ends of the two vertical plates has a groove communicating with the sliding groove. A slider is slidably installed in the strip groove, and a pressure roller is rotatably installed between the two sliders. A third motor for driving the pressure roller to rotate is installed at the slider on the right. A rack is slidably installed in the sliding groove, and the bottom end of the rack is fixedly connected to the top of the slider. A gear is rotatably installed in the groove, and the gear meshes with the rack. A drive shaft is coaxially connected between the two gears. A second motor for driving the gear to rotate is installed at the vertical plate on the right.

[0009] In addition, the adjustment device of the nonwoven fabric coating sample machine proposed in the above application may also have the following additional technical features:

[0010] Specifically, a guide rod is fixedly connected to the strip groove by bolts, and the guide rod passes through the slider and is slidably connected to the slider.

[0011] Specifically, the base has support plates fixed at the four corners of its top, a first roller is rotatably installed between the two support plates on the rear side, and a second roller is rotatably installed between the two support plates on the front side.

[0012] Specifically, the vertical plate is fixedly connected to the top of the glue tank by bolts, and the cross-sectional shape of the vertical plate is rectangular.

[0013] Specifically, a dust removal component is provided at the top of the base near the front side. The dust removal component includes a hollow shell. The outer wall of the shell has a through-hole for non-woven fabric to pass through. Multiple dust suction slots are provided on the upper and lower walls of the through-hole. Fans for conveying air to the shell are installed at the lower side of both sides of the shell. Multiple dust filters are fixed inside the shell.

[0014] Specifically, the dust filter is a metal filter, which is fixedly connected to the inner wall of the housing by bolts.

[0016] Specifically, the housing is fixedly connected to the base by bolts, and the housing is made of aluminum alloy.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The design incorporates a coating roller and a pressure roller assembly: a second motor drives a gear to rotate, which in turn causes a rack to rise and fall, which in turn causes a slider to rise and fall. As the slider rises and falls, the height of the pressure roller can be adjusted. With the adjustment of the pressure roller height, the distance between the pressure roller and the coating roller is also adjusted, thus facilitating the application of different thicknesses of adhesive to the nonwoven fabric. This design, by adjusting the height of the pressure roller, facilitates the adjustment of the adhesive coating thickness of the nonwoven fabric. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example

[0030] Please see Figures 1-3 As shown, the adjusting device of the nonwoven fabric coating sample machine includes a base 1. A glue tank 2 is fixed to the rear top of the base 1. A coating roller 20 is rotatably mounted inside the top opening of the glue tank 2. A first motor 21 for driving the coating roller 20 to rotate is installed at the right end of the glue tank 2. A pressure roller assembly 3 is provided above the coating roller 20. The pressure roller assembly 3 includes two symmetrical vertical plates 30 fixed to the top of the glue tank 2. Each vertical plate 30 has a strip groove 300. The top of the vertical plate 30 has a sliding groove 301 that communicates with the strip groove 300. Each of the two opposite ends of the two vertical plates 30 has a... A groove 302 is connected to the slide groove 301; a slider 32 is slidably installed in the strip groove 300, and a pressure roller 33 is rotatably installed between the two sliders 32. A third motor 38 for driving the pressure roller 33 to rotate is installed at the slider 32 on the right side; a rack 34 is slidably installed in the slide groove 301, and the bottom end of the rack 34 is fixedly connected to the top of the slider 32; a gear 35 is rotatably installed in the groove 302, and the gear 35 meshes with the rack 34. A drive shaft 36 is coaxially keyed between the two gears 35; a second motor 37 for driving the gear 35 to rotate is installed at the vertical plate 30 on the right side.

[0031] In this embodiment, a guide rod 31 is fixedly connected to the strip groove 300 by bolts. The guide rod 31 passes through the slider 32 and is slidably connected to the slider 32. The guide rod 31 guides the lifting and lowering movement of the slider 32, ensuring the stability of the slider 32.

[0032] In this embodiment, support plates 10 are fixed at the four corners of the top of the base 1. A first roller 11 is rotatably installed between the two rear support plates 10, and a second roller 12 is rotatably installed between the two front support plates 10. The arrangement of the first roller 11 and the second roller 12 facilitates the loading and unloading of the nonwoven fabric.

[0033] In this embodiment, the vertical plate 30 is fixedly connected to the top of the glue tank 2 by bolts, and the cross-sectional shape of the vertical plate 30 is rectangular. The rectangular vertical plate 30 has better structural strength, while the bolt fixing method ensures the reliable installation of the vertical plate 30.

[0034] It is worth noting that the first motor 21, the second motor 37, and the third motor 38 involved in this embodiment are existing conventional technologies, and will not be described in detail here.

[0035] Before use, the user first turns on the power to the second motor 37. The second motor 37 starts to work. The output shaft of the second motor 37 rotates, driving the gear 35 and the transmission shaft 36 to rotate. Since the gear 35 meshes with the rack 34, the rack 34 moves in the vertical direction and drives the slider 32 to rise and fall. The slider 32 then drives the pressure roller 33 to rise and fall. When the pressure roller 33 rises and falls to the appropriate height, the user stops the power to the second motor 37.

[0036] In practical use, the user first connects the power supply to the first motor 21 and the third motor 38. The first motor 21 and the third motor 38 start to work. The output shaft of the first motor 21 rotates, driving the coating roller 20 to rotate. The output shaft of the third motor 38 rotates, driving the pressure roller 33 to rotate. When the nonwoven fabric passes between the pressure roller 33 and the coating roller 20, the coating roller 20 can coat the nonwoven fabric with adhesive. Example

[0037] Please see Figures 4-5 As shown, this embodiment provides the following technical solution based on embodiment 1: A dust removal component 4 is provided at the top of the base 1 near the front side. The dust removal component 4 includes a hollow shell 40. The outer wall of the shell 40 is provided with a through groove 400 that penetrates the shell 40 and is used for the passage of non-woven fabric. Multiple dust suction grooves 401 are provided on the upper and lower walls of the through groove 400. Fans 41 for conveying air to the shell 40 are installed at the lower side of both sides of the shell 40. Multiple dust filter screens 42 are fixed inside the shell 40.

[0038] In this embodiment, the dust filter 42 is a metal filter, which is fixedly connected to the inner wall of the housing 40 by bolts. The metal filter has the advantages of corrosion resistance and high strength, ensuring the service life of the dust filter 42, while the bolt fixing method ensures the reliable installation of the dust filter 42.

[0039] In this embodiment, the dust collection groove 401 has a rectangular cross-sectional shape, and multiple dust collection grooves 401 are linearly and equally spaced in the horizontal direction. The multiple dust collection grooves 401 improve the dust removal effect on the non-woven fabric.

[0040] In this embodiment, the housing 40 is fixedly connected to the base 1 by bolts, and the housing 40 is made of aluminum alloy. The bolt fixing method ensures the reliable installation of the housing 40, while the aluminum alloy material has the advantage of corrosion resistance, ensuring the service life of the housing 40.

[0041] It is understandable that the dust removal component 4 can be set up to remove dust before the nonwoven fabric is coated with adhesive, so as to avoid dust and other impurities affecting the coating quality of the nonwoven fabric.

[0042] It is worth noting that the fan 41 involved in this embodiment is a conventional technology and will not be described in detail here.

[0043] In actual use, the user first connects the power supply to the ventilator 41, and the ventilator 41 starts to work. The ventilator 41 drives the airflow to the housing 40. At this time, suction is generated at multiple dust collection slots 401. When the non-woven fabric passes through the slots 400, the dust and other impurities adhering to the non-woven fabric are sucked away under the action of suction. The dust and other impurities enter the housing 40 and are intercepted and filtered by the dust filter 42.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
