Description

Technical Field

[0001] This invention relates to a gluing machine, and more particularly to an automatic gluing machine for the production of flame-retardant fabrics. Background Technology

[0002] Flame-retardant fabric is a textile material with flame-retardant properties. It undergoes special treatment to prevent the spread of fire when exposed to an ignition source. Flame-retardant fabric is typically made of flame-retardant fibers or fibers with added flame-retardant adhesives. To further improve the flame-retardant properties of the fabric and prevent flame penetration or spread, flame-retardant adhesives can be used to fill the fiber gaps, increasing the fabric's density and preventing the spread of fire and the entry of oxygen.

[0003] Currently, in the production process of flame-retardant fabric, spraying or dyeing is usually used to coat the fabric to form a flame-retardant coating. However, after the fabric is dyed or sprayed, the flame-retardant adhesive is liquid and difficult to dry quickly. The fabric needs to be placed in a well-ventilated place to air dry naturally or dried using a dryer. This results in many production steps and low production efficiency for flame-retardant fabric. Summary of the Invention

[0004] To overcome the shortcomings of low production efficiency caused by excessive production processes and long drying times after the fabric has been sprayed and impregnated with liquid flame retardant adhesive, this invention provides a highly efficient automatic gluing machine for the production of flame retardant fabric.

[0005] The technical solution is: an automatic gluing machine for flame-retardant fabric production, comprising a housing, a feeding roller, a winding roller, a guide shaft, and a coating roller. The feeding roller is located on the left side of the housing, and the winding roller is rotatably connected to the right side. The guide shaft is fixed to the upper part of the housing, and multiple coating rollers are rotatably connected to the lower part. The machine also includes a drive unit, coating cylinders, roller shafts, coating roller brushes, a material box, feed pipe one, feed pipe two, an extrusion stopper plate, a return spring, and a one-way component. Coating cylinders are connected to both the left and right sides of the middle of the housing, with two coating cylinders close to each other. One side of the coating cylinder is open, and a roller shaft is rotatably connected inside the coating cylinder. The machine housing is equipped with a drive unit for driving the winding roller and the roller shaft. A coating roller brush is connected to the roller shaft. Two material boxes are symmetrically connected to the front of the machine housing. The side of the two material boxes that are far apart from each other is connected to a feed pipe one, and the side of the two material boxes that are close to each other is connected to a feed pipe two. Feed pipe two is connected to the coating cylinder. A pressure plate is slidably connected inside the material box. The pressure plate has two openings. A return spring is connected between the material box and the pressure plate. A one-way component is provided on the pressure plate.

[0006] Furthermore, the driving components include a first drive motor, a second drive motor, gears, and a circular block. The first drive motor and the second drive motor are mounted on the rear side of the housing. The winding roller is connected to the output shaft of the first drive motor, and the output shaft of the second drive motor is connected to one of the roller shafts. Gears are connected to the front of both roller shafts, and the two gears mesh. A circular block is connected to one side of the gear at an eccentric position. After the circular block rotates with the gear, it will contact the extrusion plate.

[0007] Furthermore, the one-way component includes a baffle and a torsion spring. Two baffles are rotatably connected to the side of the extrusion plug plate near the second feed pipe. The baffles are used to block the opening of the extrusion plug plate. A torsion spring is connected between the extrusion plug plate and the baffles. A one-way valve is provided on the first feed pipe.

[0008] Furthermore, it also includes air pipe one, air box, air pipe two, connecting sleeve and piston. The air box is installed on the top of the material box. Air pipe one and connecting sleeve are connected between the air box and the material box. Air pipe two is connected between the air box and the roller shaft. One-way air valves are provided on both air pipe one and air pipe two. Fine holes are evenly spaced on the roller shaft. The piston is slidably connected between the connecting sleeve and the air box. After the extrusion plate moves, it will contact the piston.

[0009] Furthermore, it also includes a collection box, a water tank, water pipes, a water pump, and nozzles. The bottom of the coating cylinder has an opening, and the collection box is connected to the opening at the bottom of the coating cylinder. Two water tanks are connected to the rear side of the casing. A water pump is installed on the side of the two collection boxes that are far apart from each other. A water pipe is connected to the water pump. One end of the water pipe is connected to the water tank, and the other end of the water pipe is inserted into the coating cylinder and connected to multiple nozzles.

[0010] Furthermore, it also includes a scraper, with a scraper connected to the bottom of the guide shaft, which is used to scrape off dust from one side of the flame-retardant cloth.

[0011] Furthermore, it also includes a collection frame, a reciprocating screw, a rotating wheel, and a scraper. The collection frame is connected between the front wall and the rear wall of the inner casing. The reciprocating screw is rotatably connected between the front wall and the rear wall of the inner casing. Rotating wheels are connected to the left and right sides of the reciprocating screw. The scraper is slidably connected inside the collection frame. The scraper is connected to the reciprocating screw by a thread.

[0012] Furthermore, it also includes heaters, with two heaters installed in the lower part of the casing.

[0013] The beneficial effects are:

[0014] 1. This invention uses a second drive motor to drive the roller shaft to rotate, and the extrusion plate squeezes the flame retardant adhesive into the coating cylinder. A first drive motor drives the take-up roller to rotate and pull the fabric. The coating rollers on both sides rotate continuously, and the fabric is slowly pulled, so that the flame retardant can be evenly coated on the fabric. After the fabric is coated with the flame retardant adhesive, the coating roller further evenly coats the flame retardant adhesive on the fabric. Finally, it is rolled up on the take-up roller. The hot-melt flame retardant adhesive can dry quickly after being applied to the fabric, which improves the production efficiency of flame retardant fabric.

[0015] 2. This invention utilizes the heat drawn from the material tank into the coating roller brush to prevent the hot-melt flame retardant adhesive from solidifying prematurely. A water pump draws cleaning fluid from the water tank, which is then sprayed into the coating cylinder through water pipes and nozzles to clean the coating cylinder and coating roller brush.

[0016] 3. In this invention, as the fabric is pulled, the friction of the fabric drives the rotating wheel to rotate, the rotation of the rotating wheel drives the reciprocating screw to rotate, and the rotation of the reciprocating screw drives the scraper to scrape back and forth through the thread, so as to flatten the fabric. The coated fabric is heated by the heater, so that the flame retardant adhesive dries quickly. Attached Figure Description

[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0030] Example 1: An automatic gluing machine for the production of flame-retardant fabric, such as Figures 1-7As shown, the device includes a housing 1, a drive unit, a feeding roller 4, a take-up roller 5, a guide shaft 6, a coating roller 7, a coating cylinder 8, a roller shaft 81, a coating roller brush 82, a material box 9, a feed pipe 1 91, a feed pipe 2 92, a pressure stopper plate 94, a return spring 95, and a one-way component. The feeding roller 4 is placed on the left side of the housing 1 and is used to hold the fabric. The take-up roller 5 is rotatably connected to the right side of the housing 1 and is used to pull and take up the fabric. The guide shaft 6 is fixed to the upper part of the housing 1 and is used to restrict the direction of the fabric. Three coating rollers 7 are rotatably connected to the lower part of the housing 1 and are used to guide the fabric and evenly coat it with flame retardant. Coating cylinders 8 are connected to the left and right sides of the middle of the housing 1. The sides of two coating cylinders 8 that are close to each other have openings. A roller shaft 81 is rotatably connected inside the coating cylinder 8. A device for driving the take-up roller 5 and the roller is located on one side of the housing 1. The drive unit for rotating shaft 81 has a coating roller brush 82 connected to the roller shaft 81. The coating roller brush 82 is used to apply flame retardant adhesive to the fabric. The two coating roller brushes 82 are located on both sides of the fabric. Two material boxes 9 are symmetrically connected to the front side of the machine housing 1. The material boxes 9 are containers for hot-melt flame retardant adhesive. The side of the two material boxes 9 that is far apart from each other is connected to the feed pipe 1 91. The hot-melt flame retardant adhesive enters the material box 9 from the feed pipe 1 91. The side of the two material boxes 9 that is close to each other is connected to the feed pipe 2 92. The feed pipe 2 92 is connected to the coating cylinder 8. The extrusion stopper plate 94 is slidably connected inside the material box 9. The extrusion stopper plate 94 is used to squeeze the flame retardant adhesive into the coating cylinder 8 through the feed pipe 2 92. The extrusion stopper plate 94 has two openings. A return spring 95 is connected between the material box 9 and the extrusion stopper plate 94. The return spring 95 is used to return the extrusion stopper plate 94 after it has moved. The extrusion stopper plate 94 is provided with a one-way component.

[0031] like Figure 2 , Figure 3 and Figure 5 As shown, the driving components include a drive motor 2, a drive motor 3, a gear 84, and a circular block 93. The drive motor 2 and the drive motor 3 are mounted on the rear side of the housing 1. The take-up roller 5 is connected to the output shaft of the drive motor 2. The drive motor 2 is used to drive the take-up roller 5 to rotate. The output shaft of the drive motor 3 is connected to one of the roller shafts 81. The drive motor 3 is used to drive the rotation of one of the roller shafts 81. The front of both roller shafts 81 is connected to a gear 84. The two gears 84 mesh. The rotation of one roller shaft 81 drives the rotation of the other roller shaft 81 through the gear 84. A circular block 93 is connected to one side of the gear 84 at an eccentric position. After the circular block 93 rotates with the gear 84, it will contact the extrusion plate 94. The rotation of the gear 84 will drive the circular block 93 to contact and push the extrusion plate 94.

[0032] like Figures 5-7As shown, the one-way component includes a baffle 96 and a torsion spring 97. Two baffles 96 are rotatably connected to the side of the extrusion stopper 94 near the feed pipe 2 92. The baffles 96 are used to block the opening of the extrusion stopper 94. A torsion spring 97 is connected between the extrusion stopper 94 and the baffles 96. The torsion spring 97 is used to reset the baffles 96 after rotation. A one-way valve is provided on the feed pipe 1 91.

[0033] In use, the rolled fabric is placed on the feeding roller 4, pulled out, passes around the guide shaft 6, and then through the two coating roller brushes 82. The fabric continues to pass around the coating roller 7 and is then connected to the take-up roller 5. Hot-melt flame retardant adhesive is added into the material box 9 through the feed pipe 91. The roller shaft 81 is driven to rotate by the drive motor 3. The rotation of the roller shaft 81 drives the coating roller brushes 82 and gears 84 to rotate. The rotation of the gears 84 on the left and right sides drives the circular blocks 93 connected to them to rotate. After the circular blocks 93 on both sides rotate, they will contact and squeeze the extrusion plate 94 on the same side, causing the extrusion plate 94 to move away from each other. At this time, the return spring 95 is compressed. As the two extrusion plates 94 move away from each other, the flame retardant adhesive pushes open the baffle 96, and the flame retardant adhesive in the material box 9 passes through the opening to the extrusion plate 94. The material moves towards the side closer to the feed pipe 92. When the eccentrically connected circular block 93 continues to rotate and no longer squeezes the extrusion plate 94, the extrusion plate 94 moves in the opposite direction under the action of the return spring 95. The extrusion plate 94 squeezes the flame retardant adhesive through the feed pipe 92 and squeezes the flame retardant adhesive into the coating cylinder 8. After the flame retardant adhesive is squeezed onto the coating roller brush 82, the drive motor 2 drives the take-up roller 5. The take-up roller 5 rotates and pulls the fabric. By rotating the coating roller brush 82, the flame retardant adhesive is applied to the fabric in the middle. The coating roller brushes 82 on the left and right sides continue to rotate, and the fabric is slowly pulled, so that the flame retardant can be evenly coated on the fabric. After the fabric is coated with the flame retardant adhesive, the coating roller 7 further evenly coats the flame retardant adhesive on the fabric. Finally, it is wound up on the take-up roller 5. The whole coating process is simple and fast.

[0034] Example 2: Based on Example 1, such as Figure 5 and Figure 6 As shown, it also includes an air pipe 100, an air box 101, an air pipe 2 102, a connecting sleeve 103, and a piston 104. The air box 101 is installed on the top of the material box 9. The air box 101 is a container for temporarily storing hot air. The air pipe 100 and the connecting sleeve 103 are connected between the air box 101 and the material box 9. The air pipe 2 102 is connected between the air box 101 and the roller shaft 81. One-way air valves are provided on both the air pipe 100 and the air pipe 2 102. Fine holes are evenly spaced on the roller shaft 81. The piston 104 is slidably connected between the connecting sleeve 103 and the air box 101. The piston 104 is used to compress the gas. After the compression plate 94 moves, it will drive the piston 104 to move.

[0035] When the extrusion plate 94 moves to the side away from each other, it contacts and squeezes the piston 104, causing the piston 104 to move upward. The upward movement of the piston 104 forces the gas in the gas box 101 into the coating roller brush 82 through the air pipe 102 and the fine holes of the roller shaft 81. When the piston 104 moves upward and the extrusion plate 94 stops squeezing the piston 104, the piston 104 moves downward under the action of gravity. The downward movement of the piston 104 draws the hot air in the material box 9 into the air box 101. By drawing the heat from the material box 9 into the coating roller brush 82, the heat is utilized, preventing the hot-melt flame retardant adhesive from solidifying prematurely.

[0036] like Figure 8 and Figure 9 As shown, it also includes a collection tank 12, a water tank 121, a water pipe 122, a water pump 123, and a nozzle 124. The bottom of the coating cylinder 8 has an opening, and the collection tank 12 is connected to the opening at the bottom of the coating cylinder 8. The collection tank 12 is used to collect the waste liquid after cleaning. Two water tanks 121 are connected to the rear side of the housing 1. A water pump 123 is installed on the side of the two collection tanks 12 that is far away from each other. The water pump 123 is used to draw the cleaning liquid in the water tank 121. A water pipe 122 is connected to the water pump 123. One end of the water pipe 122 is connected to the water tank 121, and the other end of the water pipe 122 is inserted into the coating cylinder 8 and connected to three nozzles 124.

[0037] After coating is completed, the cleaning solution in the water tank 121 can be extracted by the water pump 123. The cleaning solution is sprayed into the coating cylinder 8 through the water pipe 122 and the nozzle 124 to clean the coating cylinder 8 and the coating roller brush 82. The waste liquid is collected through the collection box 12.

[0038] like Figure 10 and Figure 11 As shown, it also includes a scraper 13. The bottom of the guide shaft 6 is connected to the scraper 13. When the piled fabric roll is covered with dust, the dust on one side of the flame-retardant fabric can be scraped off by the scraper 13.

[0039] like Figure 10 and Figure 11 As shown, it also includes a collection frame 141, a reciprocating screw 142, a rotating wheel 143, and a scraper 144. The collection frame 141 is connected between the inner front wall and the inner rear wall of the housing 1. The reciprocating screw 142 is rotatably connected between the inner front wall and the inner rear wall of the housing 1. The left and right sides of the reciprocating screw 142 are connected to the rotating wheel 143. The rotating wheel 143 is in contact with the fabric. The fabric drives the rotating wheel 143 and the reciprocating screw 142 to rotate through friction. The scraper 144 is slidably connected inside the collection frame 141. The scraper 144 is connected to the reciprocating screw 142 by a thread.

[0040] As the fabric is being pulled, the friction causes the rotating wheel 143 to rotate, which in turn causes the reciprocating screw 142 to rotate. The rotation of the reciprocating screw 142 drives the scraper 144 to scrape back and forth through the thread, smoothing the fabric and removing dust from the other side.

[0041] like Figure 10 As shown, it also includes heaters 15. Two heaters 15 are installed in the lower part of the housing 1. The heaters 15 can heat the coated fabric to make the flame retardant adhesive dry quickly.

[0042] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
