Description

Technical Field

[0001] This utility model relates to the field of composite machine technology, and in particular to a composite machine for spreading powder on needle-punched floor mats for automotive interiors. Background Technology

[0002] The powder laminating machine uses powder transfer technology to evenly transfer hot melt adhesive powder onto the fabric. After baking, it is then thermally laminated with the fabric, allowing the molten adhesive dots to penetrate into the fabric to a certain depth, thereby bonding the two layers of fabric together.

[0003] Existing technologies, such as the automotive interior needle-punched floor mat powder spreading and compounding machine disclosed in CN212289102U, have a feeding slot at the top of the outer frame, a powder spreading slot in the middle of the outer frame, a feeding box at the top of the powder spreading slot, a screw nut on the front of the feeding box, two symmetrical crossbeams in the middle of the powder spreading slot, and symmetrical round rods on both sides of the crossbeams. The top of the screen plate has an upper baffle frame, and the bottom of the screen plate has a lower baffle frame. An installation ring is fitted onto the corresponding round rod, and a spring is fitted onto the round rod. A vibrator is also located on one side of the outer frame, and the output end of the vibrator is connected to the screen plate. This technology, through its overall structural design, improves the uniformity of powder spreading while preventing material spillage and saving raw materials. However, the following problems still exist in its use:

[0004] The powder-spraying mechanism described above sprays powder in a fixed direction. By spraying powder during the movement of the fabric, the fabric's movement speed is easily uneven, which can easily cause uneven dispersion of the PE powder on the fabric. This results in uneven distribution of the PE powder after it melts, affecting the quality of the composite fabric and easily causing problems such as delamination. Utility Model Content

[0005] The purpose of this invention is to solve the problem of uneven powder application during fabric movement in the prior art, and to propose a powder application and bonding machine for automotive interior needle-punched floor mats.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A car interior needle-punched floor mat powder spreading and laminating machine includes a housing with a hollow structure. Conveying grooves are provided on both sides of the housing, and a first fabric layer is placed in each groove. A first conveying roller is fixedly installed on the outer wall of the housing, conveying the first fabric layer into the housing. A through hole is provided on the side wall of the housing, through which a guide tube is installed. A spraying mechanism is fixedly connected to the end of the guide tube for uniformly spraying PE powder onto the first fabric layer. A heating spraying mechanism is fixedly connected to the inner wall of the housing to a heating platform for uniformly spraying PE powder onto the first fabric layer. A second conveying roller is fixedly installed on the outer wall of the housing relative to the heating platform, and a second fabric layer is placed on the second conveying roller. A support rod is fixedly connected to the outer wall of the housing, and an electric telescopic rod is fixedly connected to the lower part of the support rod. A compression roller for compressing the first and second fabric layers is fixedly connected to the lower part of the electric telescopic rod. An L-shaped bracket is fixedly connected to the outer wall of the housing, and a device for collecting the compressed first and second fabric layers is rotatably connected to the inner wall of the L-shaped bracket. The system comprises a collection roller for the layer; the spraying mechanism includes a fixed column fixed to the inner wall of the box, a T-shaped plate fixedly connected to the end of the fixed column, a drive motor fixedly mounted on the T-shaped plate, a rotating connecting rod fixedly connected to the output end of the drive motor, a sliding block rotatably connected to the rotating connecting rod via a pin, a connecting rod provided on the outer wall of the sliding block, a sliding groove for sliding the sliding block provided inside the connecting rod, a connecting frame provided on the outer wall of the sliding block at the end of the connecting rod, a sliding rod fixedly mounted on the lower part of the connecting frame, a fixed seat provided on the outer wall of the sliding rod, and a slider fixedly mounted on the lower part of the sliding rod, a powder-spreading seat for storing PE powder fixedly mounted on the lower part of the slider, and a nozzle for spraying PE powder integrally connected to the lower part of the powder-spreading seat, the drive motor fixedly mounted on the inner wall of the T-shaped plate, one end of the connecting rod rotatably connected to the upper part of the T-shaped plate via a pin, the sliding block at the end of the connecting rod slidably disposed in the sliding groove of the connecting frame, the fixed seat fixedly connected to the outer wall of the T-shaped plate, and the sliding rod slidably disposed within the fixed seat, and the guide tube fixedly mounted on the outer wall of the nozzle.

[0008] To better achieve the above objectives, the present invention adopts a further technical solution: the two support rods are distributed vertically on both sides of the first fabric layer, and the L-shaped bracket is located below the support rods located at the bottom of the first fabric layer.

[0009] To better achieve the above objectives, the present invention adopts a further technical solution: a cleaning brush cylinder for sweeping dust off the first fabric layer is provided in the conveying groove relative to the first conveying roller in the box body.

[0010] The advantages of this utility model are: by turning on the drive motor, one end of the connecting rod is fixed to the T-shaped plate, and the other end slides in the sliding groove on the connecting rod through the sliding block. This causes the connecting rod to drive the connecting frame to move back and forth repeatedly, thereby causing the sliding rod fixedly connected to the lower part of the connecting frame to drive the slider to move quickly within the fixed seat. This causes the powder-spraying seat to drive the nozzle set at the lower part to move back and forth quickly, so that the nozzle evenly sprinkles the PE powder in the powder-spraying seat onto the first fabric layer. Then, the PE powder is melted by the heating table, and the second fabric layer is attached to the surface of the first fabric layer so that they come into contact. Then, by turning on the electric telescopic rod, the extrusion roller extrudes the first and second fabric layers. This avoids uneven movement speed of the fabric during the movement process, which would lead to uneven dispersion of PE powder and cause uneven distribution of PE powder after hot melting, which could easily lead to delamination and other phenomena.

[0018] Reference Figures 1-5As shown, the automotive interior needle-punched floor mat powder spreading and laminating machine includes a housing 1, which is a hollow structure. Conveying grooves are provided on both sides of the housing 1, and a first fabric layer 4 is placed in each conveying groove. A first conveying roller 2 is fixedly installed on the outer wall of the housing 1, conveying the first fabric layer 4 into the housing 1. A through hole is provided on the side wall of the housing 1, and a guide tube 26 is installed in the through hole. A spraying mechanism is fixedly connected to the end of the guide tube 26, which is used to uniformly spray PE powder onto the first fabric layer 4. A heating spraying mechanism is fixedly connected to the inner wall of the housing 1, which uniformly sprays PE powder onto the first fabric layer 4 onto a heating platform 5. A second conveying roller 11 is fixedly installed on the outer wall of the housing 1 on the side opposite to the heating platform 5. A second fabric layer 12 is provided on top; a support rod 8 is fixedly connected to the outer wall of the box 1, and an electric telescopic rod 9 is fixedly connected to the lower part of the support rod 8. A squeezing roller 10 for squeezing the first fabric layer 4 and the second fabric layer 12 is fixedly connected to the lower part of the electric telescopic rod 9. An L-shaped bracket 6 is fixedly connected to the outer wall of the box 1. The L-shaped bracket 6 facilitates the support of the collecting roller 7. The collecting roller 7 for collecting the squeezed first fabric layer 4 and the second fabric layer 12 is rotatably connected to the inner wall of the L-shaped bracket 6. The two squeezing rollers 10 are driven to move towards each other by the electric telescopic rod 9, thereby squeezing the first fabric layer 4 and the second fabric layer 12; the two support rods 8 are distributed vertically on both sides of the first fabric layer 4, which facilitates the squeezing roller 10 to squeeze the first fabric layer 4. Layer 4 and the second fabric layer 12 are compressed. The L-shaped bracket 6 is located below the support rod 8 located below the first fabric layer 4 to facilitate the collection of the compressed fabric. The spraying mechanism includes a fixed column 13 fixed to the inner wall of the box 1. A T-shaped plate 14 is fixedly connected to the end of the fixed column 13. A drive motor 15 is fixedly installed on the T-shaped plate 14. A rotating connecting rod 16 is fixedly connected to the output end of the drive motor 15. A sliding block 17 is rotatably connected to the rotating connecting rod 16 through a pin. A connecting rod 18 is provided on the outer wall of the sliding block 17. A sliding groove 19 for sliding of the sliding block 17 is provided in the connecting rod 18. A connecting frame 20 is provided on the outer wall of the sliding block 17 at the end of the connecting rod 18. The lower part of the connecting frame 20 is fixedly installed. The device includes a sliding rod 21, a fixed seat 22 on the outer wall of the sliding rod 21, a slider 23 fixedly installed at the lower part of the sliding rod 21, a powder-spraying seat 24 for storing PE powder fixedly installed at the lower part of the slider 23, and a nozzle 25 for spraying PE powder integrally connected to the lower part of the powder-spraying seat 24; a drive motor 15 fixedly installed on the inner wall of the T-shaped plate 14; a connecting rod 18 rotatably connected to the upper part of the T-shaped plate 14 through a pin; a sliding block 17 at the end of the connecting rod 18 slidably installed in the groove of the connecting frame 20; a fixed seat 22 fixedly connected to the outer wall of the T-shaped plate 14; a sliding rod 21 slidably installed inside the fixed seat 22; and a guide tube 26 fixedly installed on the outer wall of the nozzle 25, which facilitates the replenishment of PE powder in the nozzle 25.A cleaning brush 3 is installed in the conveying groove of the housing 1 relative to the first conveying roller 2 to clean dust from the first fabric layer 4. This prevents dust from interfering with the melting of PE powder on the first fabric layer 4, thus avoiding uneven bonding between the first fabric layer 4 and the second fabric layer 12, which could lead to delamination.

[0019] In use, the first fabric layer 4 on the first conveying roller 2 is first fed into the box 1 through the conveying groove. Then, it passes through the two extrusion rollers 10 through the conveying groove at the other end of the box 1 and is finally wrapped around the collecting roller 7. Then, the drive motor 15 is turned on, so that the output end of the drive motor 15 drives the rotating connecting rod 16 to rotate. This causes one end of the connecting rod 18 to be fixed to the T-shaped plate 14, and the other end to slide through the sliding block 17 in the sliding groove 19 on the connecting rod 18. This causes one end of the connecting rod 18 to drive the connecting frame 20 to move back and forth repeatedly. This causes the sliding rod 21, which is fixedly connected to the lower part of the connecting frame 20, to slide in the fixed seat 22, driving the slider 23 to move quickly. This causes the powder-spraying seat 24 to drive the lower nozzle 25 to move back and forth repeatedly, so that the nozzle 25 evenly sprinkles the PE powder in the powder-spraying seat 24 onto the first fabric layer 4. When the first fabric layer 4 is fed into the box 1 through the conveying groove at the other end of the box 1, it is fed into the collecting roller 7. After PE powder is evenly sprinkled on the first fabric layer 4, the first fabric layer 4 is uniformly and centrally heated by the heating table 5 to melt the PE powder, thereby forming an adhesive layer on the surface of the first fabric layer 4. The first fabric layer 4 with the adhesive layer passes through the conveying groove on the other side of the box 1, while the second fabric layer 12 is attached to the surface of the first fabric layer 4 so that they come into contact. Then, the electric telescopic rod 9 is activated to move the extrusion roller 10 upward. When the first fabric layer 4 and the second fabric layer 12 are above the two extrusion rollers 10, the electric telescopic rod 9 drives the extrusion rollers 10 to move towards each other, so that the extrusion rollers 10 come into contact with the second fabric layer 12. Through the mutual extrusion action of the upper and lower extrusion rollers 10, the first fabric layer 4 and the second fabric layer 12 are extruded and bonded together with the adhesive layer formed after the PE is melted. Finally, it is wound around the collecting roller 7.
