Description

Technical Field

[0001] The present invention relates to the technical field of non-woven bag preparation, and specifically relates to a degradable non-woven bag and a preparation method thereof. Background Art

[0002] Non-woven fabric is composed of oriented or random fibers, and has the characteristics of moisture-proof, breathable, flexible, light in weight, non-flammable, easy to decompose, non-toxic and non-irritating, rich in colors, low in price, recyclable, etc. A kneader is required during the preparation process of non-woven fabric.

[0003] A patent with the patent announcement number CN215611044U discloses a kneader for antistatic non-woven bags, which relates to the technical field of non-woven fabric preparation. It includes a top frame. A communication hole penetrating the top frame is opened at the middle position of the top of the top frame. The left and right sides of the top of the top frame are symmetrically installed with second cylinders. The top positions of the two second cylinders are fixedly installed with an installation top plate. A second motor is fixedly installed at the middle position of the top of the installation top plate. The bottom output end of the second motor is fixedly installed with a connecting vertical shaft that penetrates the installation top plate and the communication hole and extends into the inner cavity of the top frame. Stirring blades are evenly sleeved at the bottom position of the connecting vertical shaft. By starting the telescopic movement of the second cylinder to drive the installation top plate and the counterweight to move synchronously, and starting the second motor to drive the connecting vertical shaft to rotate, the stirring blades are driven to rotate synchronously, so that while the stirring blades rotate, they move up and down, fully stirring the preparation raw materials at different positions and improving the stirring effect.

[0004] However, the current preparation device has the following problems: When the preparation device stirs the raw materials of non-woven fabric, the raw materials of non-woven fabric are easily adhered to the stirring blades, thereby reducing the mixing efficiency of the raw materials of non-woven fabric. Therefore, we propose a degradable non-woven bag and a preparation method thereof. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a degradable non-woven bag and a preparation method thereof, which solve the problem that when the preparation device stirs the raw materials of non-woven fabric, the raw materials of non-woven fabric are easily adhered to the stirring blades, thereby reducing the mixing efficiency of the raw materials of non-woven fabric as mentioned in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A preparation device for a degradable non-woven bag, including a preparation tank, support columns are fixed at the bottom edge of the preparation tank, a discharge pipe is embedded in the middle of the bottom surface of the preparation tank, a feed pipe is embedded at the top edge of the preparation tank, a motor is fixed at the top of the preparation tank, a stirring blade rod is fixed at the bottom of the output end of the motor, the stirring blade rod is located inside the preparation tank, and further includes an anti-adhesion device, an auxiliary discharge device and a tail gas absorption device;

[0007] Among them, the anti-adhesion device includes a slide rail column and a fixed column. The slide rail column is fixed at the top of the inner wall of the preparation tank, and the slide rail column is sleeved outside the stirring blade rod. One end of the fixed column is slidably installed inside the slide rail of the slide rail column, and the other end of the fixed column is fixed inside the U-shaped plate. The U-shaped plate is sleeved and slidably installed outside the stirring blade rod. The bottom of the U-shaped plate is hinged to one end of the hinge rod, and the other end of the hinge rod is hinged to the top of the U-shaped push plate. The U-shaped push plate is slidably installed outside the stirring blade of the stirring blade rod. At the same time, the stirring blade rod drives the fixed column to rotate through the U-shaped plate. The fixed column is restricted by the slide rail of the slide rail column and pushes the U-shaped plate to slide downward. The U-shaped plate pushes the hinge rod to drive the U-shaped push plate to push away the material adhering to the stirring blade from the hinge blade, avoiding the problem of non-woven raw materials adhering to the stirring blade, and thus improving the mixing efficiency of non-woven raw materials. A turning plate is fixed on the side of the hinge rod away from the stirring blade rod. At the same time, the hinge rod drives the turning plate to move dynamically, so that the turning plate dynamically stirs the non-woven raw materials, thereby improving the stirring and mixing effect of the non-woven raw materials.

[0008] Preferably, the auxiliary discharging device includes a fixed rod. The fixed rod is fixed at the bottom of the stirring blade rod. A spiral blade is fixed below the outer wall of the fixed rod. The stirring blade rod drives the spiral blade to rotate through the fixed rod. The spiral blade spirally discharges the non-woven raw materials in the preparation tank, thereby improving the discharging efficiency of the non-woven raw materials and avoiding the problem of blockage of the non-woven raw materials during the discharging process. An L-shaped frame is fixed above the outer wall of the fixed rod. A circular frame is fixed at the outer wall of the L-shaped frame. An arc plate is fixed at the bottom of the circular frame. At the same time, the stirring blade rod drives the L-shaped frame to rotate through the fixed rod. The L-shaped frame drives the arc plate to rotate through the circular frame. The arc plate scrapes the non-woven raw materials at the bottom of the inner part of the preparation tank, thereby avoiding the problem of precipitation of the non-woven raw materials.

[0009] Preferably, the auxiliary discharging device further includes a convex block ring and a scraping plate. The convex block ring is fixed at the bottom of the inner wall of the preparation tank. The scraping plate is slidably installed at the top of one end of the arc plate away from the circular frame. A sleeve plate is sleeved on the top of the scraping plate. A spring is arranged between the scraping plate and the sleeve plate. Both the scraping plate and the sleeve plate are in contact with the inner wall of the preparation tank. The top of the sleeve plate is in contact with the top of the inner wall of the preparation tank. At the same time, the arc plate drives the scraping plate and the sleeve plate to rotate. The scraping plate and the sleeve plate scrape the non-woven raw materials adhering to the inner wall of the preparation tank, thereby avoiding the problem that the non-woven raw materials adhere to the inner wall of the preparation tank and affect the stirring and mixing of the non-woven raw materials. A convex block is fixed at the top of the convex block ring. The left and right sides of the bottom of the scraping plate are both arranged as inclined surfaces. The convex block of the convex block ring is located on the movement track of the inclined surface of the scraping plate. At the same time, the convex block of the convex block ring pushes the scraping plate to dynamically scrape the non-woven raw materials adhering to the inner wall of the preparation tank, thereby improving the efficiency of the scraping plate in scraping off the non-woven raw materials.

[0010] Preferably, the tail gas absorption device includes a notched ring plate fixed to the top inner wall of the preparation tank. A folding bladder is fixed to the bottom of the notched ring plate. An activated carbon block is fixed to the bottom inner wall of the folding bladder. A nozzle ring is fixed to the bottom of the folding bladder. The nozzle ring is rotatably installed on the outer wall of a U-shaped disk. The U-shaped disk drives the nozzle ring to move synchronously. The nozzle ring continuously squeezes or stretches the folding bladder, so that the tail gas in the preparation tank is inhaled into the folding bladder by the nozzle ring. The activated carbon block purifies the tail gas, thus avoiding the problem that the tail gas in the preparation tank pollutes the production environment. A number of flapping plates are fixed to the outer wall of the nozzle ring. At the same time, the nozzle ring drives the flapping plates to flap the air inside the preparation tank, so that the purified tail gas can quickly fill the preparation tank, thereby indirectly improving the efficiency of tail gas purification.

[0012] S1. Put the non-woven fabric raw material into the preparation tank through the feed pipe of the preparation tank;

[0013] S2. Start the motor, and the motor drives the stirring blade rod to stir and mix the non-woven fabric raw material;

Through the setting of the anti-adhesion device, the motor, the stirring blade rod, the U-shaped disk, the fixed column and the slide rail column cooperate to push the articulated rod to drive the U-shaped push plate to push away the adhesion on the stirring blade from the articulated blade, avoiding the problem that the non-woven fabric raw material adheres to the stirring blade, and thus improving the mixing efficiency of the non-woven fabric raw material; at the same time, the articulated rod drives the turning plate to move dynamically, so that the turning plate dynamically stirs the non-woven fabric raw material, thereby improving the stirring and mixing effect of the non-woven fabric raw material.

[0018] (2) By setting up the auxiliary discharging device, the stirring blade rod and the fixed rod cooperate to drive the spiral blade to spirally discharge the non-woven fabric raw materials in the preparation tank, thereby improving the discharging efficiency of the non-woven fabric raw materials and avoiding the problem of blockage during the discharging process; at the same time, when the stirring blade rod stirs the non-woven fabric raw materials, the stirring blade rod, the fixed rod, the L-shaped frame and the circular frame cooperate to drive the arc plate to scrape the non-woven fabric raw materials at the bottom inside the preparation tank, thereby avoiding the problem of precipitation of the non-woven fabric raw materials; at the same time, the arc plate drives the scraping plate and the sleeve plate to scrape the non-woven fabric raw materials adhering to the inner wall of the preparation tank, thereby avoiding the problem that the non-woven fabric raw materials adhere to the inner wall of the preparation tank and affect the stirring and mixing of the non-woven fabric raw materials; at the same time, the bumps on the bump ring push the scraping plate to dynamically scrape the non-woven fabric raw materials adhering to the inner wall of the preparation tank, thereby improving the efficiency of the scraping plate to scrape off the non-woven fabric raw materials.

[0019] (3) By setting up the tail gas absorption device, the U-shaped disc and the air nozzle ring cooperate to continuously squeeze or stretch the folding bag by the air nozzle ring, so that the tail gas in the preparation tank is inhaled into the folding bag by the air nozzle ring, and the activated carbon block will purify the tail gas, thereby avoiding the problem that the tail gas in the preparation tank will pollute the production environment; at the same time, the air nozzle ring drives the fan plate to fan the air inside the preparation tank, so that the purified tail gas can quickly fill the preparation tank, thereby indirectly improving the efficiency of tail gas purification.

[0035] Example 2: A preparation method of a degradable non-woven bag, comprising the following steps

[0036] S1. Put the non-woven fabric raw material into the preparation tank 1 through the feed pipe 13 of the preparation tank 1;

[0037] S2. Start the motor 14, and the motor 14 drives the stirring blade rod 15 to stir and mix the non-woven fabric raw material;

[0038] S3. Meter the mixed non-woven fabric raw material through a gear pump. The metered mixed raw material enters the die head of the spinning machine and is spun through the spinneret of the spinning machine to form composite fibers;

[0039] S4. Lay the composite fibers evenly on the mesh curtain in sequence and reinforce to obtain the environmentally friendly degradable non-woven fabric.

[0040] During use, put the non-woven fabric raw material into the preparation tank 1 through the feed pipe 13 of the preparation tank 1, start the motor 14, and the motor 14 drives the stirring blade rod 15 to stir and mix the non-woven fabric raw material. At the same time, the stirring blade rod 15 drives the fixed column 22 to rotate through the U-shaped plate 23. The fixed column 22 slides inside the slide rail of the slide rail column 21. The fixed column 22 is restricted by the slide rail of the slide rail column 21 and pushes the U-shaped plate 23 to slide down along the stirring blade rod 15. The U-shaped plate 23 pushes the articulated rod 24 to drive the U-shaped push plate 26 to slide along the outer wall of the stirring blade of the stirring blade rod 15, so that the U-shaped push plate 26 pushes the material adhered to the stirring blade away from the articulated blade, avoiding the problem of non-woven fabric raw material adhering to the stirring blade, and thus improving the mixing efficiency of the non-woven fabric raw material; at the same time, the articulated rod 24 drives the turning plate 25 to move dynamically, so that the turning plate 25 dynamically stirs the non-woven fabric raw material, thereby improving the stirring and mixing effect of the non-woven fabric raw material. When the non-woven fabric raw material is mixed well, open the discharge pipe 11 to discharge the non-woven fabric raw material. Then, meter the mixed non-woven fabric raw material through a gear pump. The metered mixed raw material enters the die head of the spinning machine and is spun through the spinneret of the spinning machine to form composite fibers. Lay the composite fibers evenly on the mesh curtain in sequence and reinforce to obtain the environmentally friendly degradable non-woven fabric.

[0041] Meanwhile, when discharging the non-woven fabric raw material, the stirring blade rod 15 drives the spiral blade 32 to rotate through the fixed rod 31, and the spiral blade 32 spirally discharges the non-woven fabric raw material in the preparation tank 1, thereby improving the discharging efficiency of the non-woven fabric raw material and avoiding the problem of blockage of the non-woven fabric raw material during the discharging process. Meanwhile, when the stirring blade rod 15 stirs the non-woven fabric raw material, the stirring blade rod 15 drives the L-shaped frame 33 to rotate through the fixed rod 31, and the L-shaped frame 33 drives the arc plate 35 to rotate through the circular frame 34. The arc plate 35 scrapes the non-woven fabric raw material at the bottom inside the preparation tank 1, thereby avoiding the problem of precipitation of the non-woven fabric raw material. Meanwhile, the arc plate 35 drives the scraping plate 37 and the sleeve plate 38 to rotate, and the scraping plate 37 and the sleeve plate 38 scrape the non-woven fabric raw material adhered to the inner wall of the preparation tank 1, thereby avoiding the problem that the non-woven fabric raw material adheres to the inner wall of the preparation tank 1 and affects the stirring and mixing of the non-woven fabric raw material. Meanwhile, when the scraping plate 37 moves to the convex block of the convex block ring 36, the convex block of the convex block ring 36 pushes the inclined surface of the scraping plate 37 to push the scraping plate 37 to move upward along the inside of the sleeve plate 38, thereby enabling the scraping plate 37 to dynamically scrape the non-woven fabric raw material adhered to the inner wall of the preparation tank 1, thereby improving the efficiency of the scraping plate 37 scraping off the non-woven fabric raw material.

[0042] Meanwhile, each time the U-shaped plate 23 slides up and down along the outer wall of the stirring blade rod 15, the U-shaped plate 23 drives the air nozzle ring 43 to move synchronously. The air nozzle ring 43 continuously squeezes or stretches the folding bladder 42, so that the tail gas in the preparation tank 1 is sucked into the folding bladder 42 by the air nozzle ring 43, and the activated carbon block 44 purifies the tail gas, thereby avoiding the problem that the tail gas in the preparation tank 1 pollutes the production environment. Meanwhile, when the air nozzle ring 43 moves, it drives the fan plate 45 to move synchronously, and the fan plate 45 fans the air inside the preparation tank 1, so that the purified tail gas can quickly fill the preparation tank 1, thereby indirectly improving the efficiency of tail gas purification.

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.
