Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric gluing, in particular to a non-woven fabric gluing device. Background Technique

[0002] Non-woven fabric, also known as non-woven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., is produced from polyester fiber and polyester fiber materials and is made through a needle-punching process. Different thicknesses, hand feelings, hardnesses, etc. can be made. During the production process of non-woven fabric, gluing processing is required to facilitate the bonding of the non-woven fabric.

[0003] The existing technology has the following deficiencies: In the existing non-woven fabric gluing device, the glue is coated on the surface of the non-woven fabric through a glue-coated round roller. The bottom end of the round roller is kept immersed in the glue. As the glue decreases, the glue needs to be continuously added to increase the liquid level of the glue. Moreover, during the coating process, the pressing roller and the coating roller cannot maintain the same linear speed, which is likely to cause scratches on the surface of the non-woven fabric, thus affecting the quality of the non-woven fabric. Summary of the Utility Model

[0004] In order to solve the problems mentioned in the above background technique, the utility model provides a non-woven fabric gluing device.

[0005] In order to achieve the above object, the utility model adopts the following technical scheme:

[0006] A non-woven fabric gluing device includes a colloid storage box. A first bracket is fixed at the top end of the colloid storage box. A coating roller and a pressing roller are rotatably installed on the first bracket in a distributed manner. The bottom end of the coating roller extends into the interior of the colloid storage box. An elevating scraper is provided on one side of the coating roller above the colloid storage box. An elevating plate is installed inside the colloid storage box. The periphery of the elevating plate is in smooth contact with the inner wall of the colloid storage box. An elevating driving mechanism is installed on the colloid storage box. The output end of the elevating driving mechanism is connected to the elevating plate.

[0007] Preferably, the elevating driving mechanism includes a hydraulic cylinder and an oil pump. The output end of the hydraulic cylinder is fixed with a second bracket. The second bracket is fixed to the top end of the elevating plate. There are two hydraulic cylinders, and the inlets of both hydraulic cylinders are communicated with the outlet of the oil pump.

[0008] Preferably, a fixing plate is installed at the top end of the colloid storage box. A push rod motor is fixed at the top end of the fixing plate. The output shaft of the push rod motor is fixed to the elevating scraper.

[0009] Preferably, guide rods are fixed on both sides of the push rod motor at the bottom end of the elevating scraper. The bottom ends of the guide rods penetrate through the fixing plate through guide holes.

[0010] Preferably, a rotary motor is fixed on one side of the colloid storage box. The output shaft of the rotary motor is fixed to the rotating shaft of the coating roller. On the first bracket on the side of the top of the colloid storage box away from the rotary motor, a first gear, a second gear, a first pulley and a second pulley are respectively rotatably installed. The first gear and the second gear mesh with each other. The first gear is fixed to the rotating shaft of the pressing roller. The second gear and the first pulley slide on the same rotating shaft. A belt is sleeved on the outer sides of the first pulley and the second pulley.

[0011] Preferably, the first gear and the second gear have the same diameter, and the diameter ratio between the coating roller and the pressing roller is equal to the diameter ratio between the second pulley and the first pulley.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The lower half of the coating roller is immersed in the colloid in the colloid storage box, so that the colloid will be continuously replenished on the surface of the coating roller during the rotation of the coating roller. The non-woven fabric passes through between the coating roller and the pressing roller and is extruded towards the coating roller by the pressing roller, so as to evenly and continuously coat the colloid on the surface of the non-woven fabric. During the rotation of the coating roller, the lifting scraper can scrape off the excess colloid on the surface of the coating roller. The lifting driving mechanism can drive the lifting plate to lift. The colloid is located at the top of the lifting plate. When the lifting plate rises, it can drive the colloid to move upward, ensuring that when a part of the colloid is consumed, the lower half of the coating roller can still be kept immersed in the colloid;

[0014] 2. The lifting scraper is driven by a push rod motor, so that the lifting scraper can approach and move away from the coating roller. During the gluing process, a certain distance is left between the lifting scraper and the coating roller, so as to scrape off the excess colloid on the surface of the coating roller. During cleaning, the lifting scraper can be pushed to contact the surface of the coating roller, so as to scrape off the colloid on the surface of the coating roller, making the cleaning more convenient;

[0015] 3. Since the second pulley and the pressing roller have the same angular velocity, and the first pulley, the first gear, the second gear and the pressing roller also have the same angular velocity, the second pulley and the first pulley have the same linear velocity of rotation, and the coating roller and the pressing roller also have the same linear velocity of rotation (scaled up proportionally), so that the non-woven fabric passing between the coating roller and the pressing roller will not slip, preventing abrasion on the surface of the non-woven fabric.

[0026] The lower half of the coating roller 7 is immersed in the colloid in the colloid storage tank 1, so that the colloid will be continuously replenished on its surface during the rotation of the coating roller 7. The non-woven fabric passes through between the coating roller 7 and the pressing roller 8 and is extruded towards the coating roller 7 by the pressing roller 8, so as to uniformly and continuously coat the colloid on the surface of the non-woven fabric. During the rotation of the coating roller 7, the lifting scraper 16 can scrape off the excess colloid on the surface of the coating roller 7. The lifting drive mechanism can drive the lifting plate 2 to lift and lower. The colloid is located at the top of the lifting plate 2. When the lifting plate 2 rises, it can drive the colloid to move upward to ensure that when a part of the colloid is consumed, the lower half of the coating roller 7 can still remain immersed in the colloid.

[0027] Among them, the lifting drive mechanism includes a hydraulic cylinder 3 and an oil pump 5. A second bracket 4 is fixed to the output end of the hydraulic cylinder 3, and the second bracket 4 is fixed to the top end of the lifting plate 2. There are two hydraulic cylinders 3, and the inlets and outlets of the two hydraulic cylinders 3 are both communicated with the outlet of the oil pump 5;

[0028] The oil pump 5 is used to synchronously drive the two hydraulic cylinders 3 to extend and contract, so as to drive the lifting plate 2 to lift and move.

Then, the first pulley 12 is driven to rotate through a belt, and further the second gear 11 is driven to rotate. Finally, the pressing roller 8 is driven to rotate through the meshing of the second gear 11 and the first gear 10, and the rotation directions of the pressing roller 8 and the coating roller 7 are opposite, so that the non-woven fabric can continuously move during the coating process.
