Description

Technical Field

[0001] This utility model belongs to the technical field of carpet laminating machines, specifically relating to a powder dispersing mechanism for carpet laminating machines. Background Technology

[0002] A carpet laminating machine is a piece of equipment used to manufacture carpet composite materials. It can laminate carpet layers of different materials, thereby improving the carpet's wear resistance, slip resistance, and comfort. The main function of a carpet laminating machine is to bond two or more layers of materials together with adhesives, and it is commonly used in the lamination process of carpets, fabrics, sponges, and other materials.

[0003] The common function of a powder-spreading mechanism is to apply adhesive powder to fabric. The spreading device includes a frame, storage bin, powder-spreading roller, drive motor, powder sieve, and vibrating motor. The storage bin is equipped with a manual stirring device to agitate the adhesive powder, ensuring a more even distribution. A vibrating motor is installed at the top of the powder sieve to improve the uniformity of powder spreading. A powder collection box is located below the conveyor belt to collect excess powder. Common powder-spreading mechanisms on the market often lack uniformity, resulting in large powder particles that are not finely applied. The scattered powder also tends to scatter and pollute the air. Furthermore, the distances between the scraper and the roller, as well as between the brush and the roller, are fixed, resulting in limited flexibility.

[0004] In summary, existing technologies suffer from problems such as insufficiently fine and even powder distribution, air pollution from powder falling into the air, impacting operator safety, and poor flexibility in controlling the distance between the roller, scraper, and brush.

[0012] Optionally, the scraper structure includes a second stabilizing block, the inner side of which is fixed to the two lower sides of the powder-spreading hopper by a fixing layer, a fixing plate fixed to the bottom of the second stabilizing block by an adjusting block, a scraper above the fixing plate, and the upper half of the adjusting block connected to the outer side of the second stabilizing block and the lower half connected to the fixing plate.

[0013] Optionally, the gap adjustment device includes a limiting frame, with a first bolt post in the middle inside the limiting frame. The first bolt post is connected to a second spiral handle on the outside. Connecting posts are provided at the same height on both sides of the first bolt post.

[0016] In summary, this utility model has at least one of the following beneficial effects:

[0017] This invention uses a vacuum pump to draw powder into a powder hopper. It interacts with two limit switches. When the lower limit switch is not blocked by EVA powder, powder is drawn and added until the upper limit switch is blocked. During this process, the powder leveling motor drives the powder leveling baffle to move left and right to evenly distribute the powder to both sides of the powder hopper, preventing powder from accumulating in one place, reducing the trouble of manual powder addition, and making it easier to operate.

[0018] This invention uses a brush to spread powder, which is more precise than the traditional roller-type powder spreading method. The brush is oscillating left and right at high frequency to spread and disperse the powder. As the powder falls, it passes through a double-layer high-frequency vibrating screen to further sieve the hot melt powder evenly.

[0019] This invention features a negative pressure suction port on the side of the waste hopper. This port uses a slight negative pressure to guide the scattered powder through airflow, preventing it from flying everywhere. This not only solves the pollution problem but also ensures that the powder is scattered more evenly, thus protecting the health and safety of the operators.

[0020] This invention allows for adjustment of the gap between the scraper and the drive roller by adjusting the adjusting block with a fine-tuning screw, and further enhances the flexibility of adjusting the gap between the brush and the drive roller by using a brush gap adjustment device.

[0031] The following is in conjunction with the appendix Figure 1-8 This utility model will be described in further detail below.

[0032] Example 1, refer to Figure 1-8In this embodiment, the existing technology addresses the problems of insufficiently fine and uniform powder distribution, air pollution caused by powder falling into the air, impacting operator safety, and poor flexibility in controlling the distance between the roller, scraper, and brush. This utility model discloses a powder dispersing mechanism for a carpet laminating machine, including a first heat dissipation box 1 and a second heat dissipation box 8, which are connected by two fixed cross columns 2. An automatic powder suction machine 5 is set above the fixed cross columns 2 via a support frame 4. A powder dispersing motor 7 is fixed on the second heat dissipation box 8 and is connected to a powder dispersing device 6. A powder spreading hopper 3 is fixedly installed below the fixed cross columns 2. A transmission roller 21 is provided below the powder spreading hopper 3. A scraper structure 14 is provided on the upper side of the transmission roller 21 and a powder brush structure is provided on the lower side. A double-layer vibrating screen 30 is provided below the powder brush structure. A waste hopper 9 is located below the transmission roller 21. A negative pressure suction port 10 is provided on the side of the waste hopper 9 and a waste collection port 12 is provided at the bottom. The powder brush structure is controlled by a gap adjustment device 22. The first heat dissipation box 1 contains a drive motor assembly. Above the drive motor assembly is the first motor 44, which is connected to the stabilizing structure 45. The stabilizing structure 45 contains a rotating column and a gear, which are compatible with each other. The gear is fixedly connected by a through column. The other side of the through column is connected to a small gear on the inner side of the first heat sink 1. The small gear is connected to a rotating gear 48. The rotating gear 48 is connected to the annular connection port 20 on the side of the transmission roller 21. The second motor 46 is located on the upper side inside the first heat sink 1 and is connected to the cam high-frequency swing mechanism 28 through a connecting rod 47. The cam high-frequency swing mechanism 28 is connected to the double-layer vibrating screen 30. The drive motor assembly is fixed by the first support plate 27.

[0033] Detailed Implementation: The negative pressure suction port 10 on the side of the waste hopper 9 uses a slight negative pressure to guide the scattered powder through the gas, preventing it from flying everywhere. When the first motor 44 starts, the rotating column inside the stabilizing structure 45 rotates, driving the internal gears to rotate. Because the gears and pinions are fixedly connected by a through column, the pinion also rotates. The rotating gear 48 and the transmission roller 21 pass through the inner side of the first heat sink 1 and are engaged with the pinion. When the pinion rotates, it drives the rotating gear 48 to rotate, which in turn drives the transmission roller 21 to rotate. The second motor 46 is connected to the inner side of the first heat sink 1 via a connecting rod 47. The cam high-frequency oscillation mechanism 28 is connected to it below. When the second motor 46 works, the connecting rod 47 vibrates, and the cam high-frequency oscillation mechanism 28 also vibrates, thereby driving the double-layer high-frequency vibrating screen 30 to vibrate, further sieving the hot melt powder.

[0034] The automatic powder suction machine 5 is a stainless steel bucket with an internal vacuum pump. The powder dispensing hopper 3 is equipped with an upper limit switch 25, and below the upper limit switch 25 is a lower limit switch 26. The upper limit switch 25 and the lower limit switch 26 are photoelectric switches that are opposite each other. The vacuum pump is controlled by a PLC.

[0035] Specific implementation method: The upper limit switch 25 and the lower limit switch 26 control the vacuum pump inside the automatic powder suction machine 5 through the PCL to complete the powder suction function. The upper limit switch 25 is generally set at the bottom and the lower limit switch 26 is generally set at the top. When the EVA powder does not block the lower limit switch 26, the automatic powder suction machine 5 starts. When the EVA powder blocks the upper limit switch 25, the automatic powder suction machine 5 stops suctioning powder.

[0036] The other side of the powder leveling device 6 is fixed on the first heat dissipation box 1. The powder leveling device 6 is a lead screw with a positive and negative thread screw above it. An L-shaped powder leveling baffle 15 is provided on the positive and negative thread screw. Heat dissipation holes 13 are provided on the outer side of the first heat dissipation box 1 and the second heat dissipation box 8. A powder baffle 16 is provided on the inner side of the powder spreading hopper 3. The powder baffle 16 is adapted to the powder leveling baffle 15.

[0037] Specific implementation method: The L-shaped powder equalization baffle 15 set on the positive and negative threaded screw is adapted to the positive and negative threaded screw to ensure that when the powder equalization motor 7 is turned on, the powder equalization baffle 15 can move left and right to evenly distribute the powder from the middle to both sides. Therefore, the length of the powder equalization baffle 15 is adapted to the width of the powder spreading hopper 3.

[0038] The painting structure includes a first stabilizing block 11, the inner side of which is connected to an arc-shaped plate 18 via a first connecting block 31. A painting brush 32 is disposed on the inner side of the arc-shaped plate 18. The two sides of the first stabilizing block 11 are fixed to a gap adjustment device 22 via second connecting blocks 24. The gap adjustment device 22 is fixed to the inner sides of the first heat sink 1 and the second heat sink 8 via a second support plate 29. The painting structure is symmetrically distributed on both sides of the transmission roller 21. The gap adjustment device 22 includes a limiting frame 37, with a first bolt post 38 disposed in the center of the limiting frame 37. The first bolt post 38 is connected to a second spiral handle 43 on the outer side. Connecting posts 36 are provided at the same height on both sides of the first bolt post 38. The moving block 49 is penetrated by the first bolt post 38 and the connecting posts 36, and there is an inner spiral in the middle that is adapted to the first bolt post 38. An upper pressure plate 40 and a lower pressure plate 42 are provided at the connection between the second spiral handle 43 and the side of the limiting frame 37. The upper pressure plate 40 and the lower pressure plate 42 are fixedly connected on one side and connected on the other side through the second bolt post 41. A first rotating handle 39 is provided above the upper pressure plate 40 to be adapted to the second bolt post 41.

[0039] Detailed implementation: The first stabilizing block 11 is fixed on both sides of the second connecting block 24. When the second spiral handle 43 is rotated, the second connecting block 24 moves back and forth on the first bolt post 38 and the connecting post 36, thereby driving the paint structure to move back and forth. After the position is determined, the pressure applied to the upper pressure plate 40 by rotating the first rotating handle 39 is used to fix the first bolt post 38, ensuring that it will not move randomly when the paint 32 is working. The arc plate 18 is designed to block EVA powder, so that more EVA powder falls into the double-layer vibrating screen 30 to avoid waste.

[0040] The scraper structure 14 includes a second stabilizing block 35. The inner side of the second stabilizing block 35 is fixed to the two lower sides of the powder spreading hopper 3 via a fixing layer 19. A fixing plate 34 is fixed to the bottom of the second stabilizing block 35 via an adjusting block 17. The scraper 33 is located above the fixing plate 34. The upper half of the adjusting block 17 is connected to the outer side of the second stabilizing block 35, and the lower half is connected to the fixing plate 34. A circular ruler is provided next to the adjusting block 17, and the distance between the scraper 33 and the drive roller 21 is indicated by the scale.

[0041] Detailed implementation: This application provides multiple adjusting blocks 17. By adjusting the position of the bottom fixed pressure plate 34 with fine-tuning screws, the distance between the scraper 33 and the transmission roller 21 can be controlled. When the gap between the scraper 33 and the transmission roller 21 is large, the scraper 33 is pressed against the fine-tuning screw, and the gap between the scraper 33 and the transmission roller 21 will decrease. If the fine-tuning of multiple adjusting blocks 17 is the same, the thickness of the powder will be consistent. Each adjusting block 17 is equipped with a corresponding circular ruler. When the fine-tuning screw is turned, the circular ruler will rotate accordingly, thereby controlling the fine-tuning situation and knowing the distance between the scraper 33 and the transmission roller 21, ensuring that the distance between the scraper 33 and the transmission roller 21 corresponding to multiple adjusting blocks 17 is consistent.

[0042] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
