Description

Technical Field

[0001] The embodiments of this disclosure relate to the field of grass fiber processing technology, and more specifically, to a grass fiber weaving device with adjustable density. Background Technology

[0002] Artificial turf is increasingly used in modern landscapes, sports facilities and other fields. Traditional grass fiber weaving and forming methods have many drawbacks. In the past, density adjustment during grass fiber weaving mainly relied on manual experience, which was not only inefficient but also difficult to accurately control the spacing between grass fibers, resulting in inconsistent appearance and performance of the turf. In terms of molding process, in the early days, a simple adhesive application method was used to fix the grass fibers to the base. Uneven distribution of adhesive easily caused the grass fibers to fall off, affecting the service life of the turf. Although a hot melt process was introduced later, the equipment was rudimentary and the molding tray was just an ordinary container. It was impossible to accurately control the amount and distribution of hot melt material, resulting in poor fusion effect at the bottom of the grass fibers. When subjected to external force, the grass fibers easily spread out from the bottom. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide an adjustable density grass fiber weaving device, which solves the technical problem that in the early technology, the grass fibers were fixed to the base by a simple adhesive application method. The uneven distribution of the adhesive easily caused the grass fibers to fall off, affecting the service life of the turf. Although a hot-melt process was introduced later, the equipment was rudimentary and the forming plate was just an ordinary container, which could not accurately control the amount and distribution of hot-melt material injected, resulting in poor fusion effect at the bottom of the grass fibers.

[0004] According to one aspect, at least one embodiment of this disclosure provides an adjustable density grass fiber weaving device, comprising: A processing rack, wherein a forming disc is provided on the upper end surface of the processing rack; A feeding and shaping assembly is disposed above the forming disc; A sliding hot melt assembly, wherein the sliding hot melt assembly is disposed on the processing frame; The feeding and shaping assembly includes a lifting rod, which is disposed on the side wall of the processing frame. A support frame is disposed on the processing frame. A feeding tray is disposed on the upper end face of the support frame. A shaping groove is disposed on the upper end face of the feeding tray. A positioning ring is disposed on the side wall of the feeding tray. The lifting rod is inserted into the interior of the positioning ring. A lower pressure plate is disposed on the upper end face of the lifting rod. A shaping strip is disposed on the lower end face of the lower pressure plate.

[0005] As a further technical solution, the shaping strip is embedded inside the shaping groove, and there is a number of shaping strips and shaping grooves, with the positions of the shaping strips and shaping grooves corresponding to each other.

[0006] As a further technical solution, the sliding hot melt assembly includes a sliding track, which is opened on the upper end face of the processing frame. The lower end of the forming disc is embedded in the sliding track and slides through a sliding wheel. A push rod is provided on the lower end face of the processing frame, and a push frame is provided at the end of the push rod. A sliding piece is connected to the side wall of the push frame, and a cutting piece is provided at the end of the sliding piece.

[0007] As a further technical solution, a limiting clamp is provided on the upper end face of the processing frame, the sliding piece is embedded inside the limiting clamp, and the cutting piece is in contact with the upper end face of the feeding tray.

[0008] As a further technical solution, the lower end face of the processing frame is provided with support legs, and the number of support legs is several, with several support legs located at the four corners of the lower end face of the processing frame.

[0009] As a further technical solution, the outer wall of the support leg is provided with a mounting plate, and the lifting rod is mounted on the mounting plate.

[0010] As a further technical solution, the pressure plate and the support frame are fitted together, and the support frame is located on opposite sides of the pressure plate.

[0011] As a further technical solution, a mounting frame is provided on the lower end face of the processing frame, and the mounting frame is movably connected to the push rod.

[0012] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, a hot-melt material is injected into the molding disc. Utilizing the excellent heat insulation properties of the molding disc and the characteristics of the hot-melt material, the bottom of the grass fibers can be fully soaked and tightly fused with the hot-melt material. This integrated fusion method results in a grass fiber bottom structure with a strength far exceeding that of traditional bonding methods, greatly enhancing the connection between the grass fibers and the substrate. In actual use, when the artificial turf is subjected to frequent trampling, pulling, and other external forces, the grass fibers are less likely to fall off, effectively extending the service life of the turf and reducing maintenance costs.

[0021] like Figures 1-4 As shown, it illustrates an adjustable density grass fiber weaving device of this disclosure, comprising: Processing rack 1, with a forming disc 2 provided on the upper end surface of processing rack 1; Feeding and shaping component 3 is positioned above forming disc 2; Sliding hot melt assembly 4 is mounted on processing frame 1; The feeding and shaping assembly 3 includes a lifting rod 3-1, which is set on the side wall of the processing frame 1. A support frame 3-5 is set on the processing frame 1. A feeding plate 3-6 is set on the upper end face of the support frame 3-5. A shaping groove 3-7 is set on the upper end face of the feeding plate 3-6. A positioning ring 3-2 is set on the side wall of the feeding plate 3-6. The lifting rod 3-1 is inserted into the interior of the positioning ring 3-2. A lower pressure plate 3-3 is set on the upper end face of the lifting rod 3-1. A shaping strip 3-4 is set on the lower end face of the lower pressure plate 3-3.

[0022] The sliding hot melt assembly 4 includes a sliding track 4-1, which is located on the upper surface of the processing frame 1. The lower end of the forming disc 2 is embedded in the sliding track 4-1 and slides through a sliding wheel. A push rod 4-2 is provided on the lower surface of the processing frame 1. A push frame 4-3 is provided at the end of the push rod 4-2. A sliding piece 4-4 is connected to the side wall of the push frame 4-3. A cutting piece 4-5 is provided at the end of the sliding piece 4-4.

[0023] In some examples, the processing frame 1, as the basic load-bearing component of the entire device, needs to be placed horizontally first. Then, the support legs 4-7 are fixed to the four corners of the lower end face of the processing frame 1. The support frame 3-5 is then fixed to the side wall of the processing frame 1. The function of the support frame 3-5 is to provide stable support for the feeding tray 3-6 and to form lateral limits on the lower pressure plate 3-3 to prevent it from shifting when descending. The feeding tray 3-6 is then placed on the upper end face of the support frame 3-5. The shaping groove 3-7 on the upper end face of the feeding tray 3-6 is used to neatly place the straw fibers, ensuring that the straw fibers are arranged according to the preset trajectory. The positioning ring 3-2 on the side wall of the feeding tray 3-6 is used to insert the lifting rod 3- 1. Provide vertical guidance for the lifting rod 3-1 to prevent it from shaking during operation. Fix one end of the lifting rod 3-1 to the mounting plate 5 and insert the other end into the positioning ring 3-2. The function of the lifting rod 3-1 is to drive the lower pressure plate 3-3 to move up and down. The shaping strip 3-4 on the lower end face of the lower pressure plate 3-3 needs to correspond to the position of the shaping groove 3-7 on the feeding plate 3-6. The function of the shaping strip 3-4 is to embed into the shaping groove 3-7, squeeze the straw to adjust the density, and fix the position of the straw to prevent the straw from shifting during subsequent hot melting. After assembly, the smoothness of the lifting rod 3-1 should be tested to ensure that the shaping strip 3-4 can be accurately embedded in the shaping groove 3-7.

[0024] Embed the lower end of the forming disc 2 into the sliding track 4-1 on the upper surface of the processing frame 1. The function of the sliding track 4-1 is to guide the horizontal movement of the forming disc 2, so as to achieve the alignment and resetting of the forming disc 2 and the feeding disc 3-6. The sliding wheel at the bottom of the forming disc 2 can reduce the friction between the forming disc 2 and the track, so that the forming disc 2 can move more flexibly. Fix the push rod 4-2 on the mounting frame 6 on the lower surface of the processing frame 1. Install the cutting piece 4-5 at the end of the sliding piece 4-4. The cutting piece 4-5 needs to be in contact with the upper surface of the feeding disc 3-6. The function of the cutting piece 4-5 is to cut the fused grass fibers later. According to the weaving requirements, the grass fibers are evenly spread in the shaping groove 3-7 of the feeding disc 3-6. The shaping groove 3-7 can limit the arrangement range of the grass fibers and ensure that the grass fibers are evenly distributed. At this time, the position of the feeding disc 3-6 needs to be adjusted so that the bottom of the grass fibers extends to the area above the forming disc 2, so as to prepare for the bottom of the grass fibers to contact the hot melt material during subsequent hot melting.

[0025] like Figures 1-4 As shown, in this embodiment, the shaping strip 3-4 is embedded inside the shaping groove 3-7. There are several shaping strips 3-4 and shaping grooves 3-7, and the positions of the several shaping strips 3-4 and shaping grooves 3-7 correspond to each other.

[0026] For example, such as Figure 1 As shown, a limiting clamp 4-6 is provided on the upper end face of the processing frame 1, the sliding piece 4-4 is embedded inside the limiting clamp 4-6, and the cutting piece 4-5 is in contact with the upper end face of the feeding tray 3-6.

[0027] In some examples, the limiting clamp 4-6 on the upper surface of the processing frame 1 is used to embed the sliding piece 4-4, providing a moving guide for the sliding piece 4-4 and preventing the sliding piece 4-4 from shifting and causing inaccurate cutting position.

[0028] For example, such as Figure 1 As shown, the lower end face of the processing frame 1 is provided with support legs 4-7. There are several support legs 4-7, and several support legs 4-7 are located at the four corners of the lower end face of the processing frame 1. The outer side wall of the support legs 4-7 is provided with mounting plates 5, and the lifting rod 3-1 is mounted on the mounting plates 5.

[0029] In some examples, the function of the support leg 4-7 is to stabilize and support the processing frame 1, preventing the device from tilting during processing; at the same time, the mounting plate 5 on the outer wall of the support leg 4-7 is used to fix the lifting rod 3-1, ensuring that the lifting rod 3-1 remains vertically stable during subsequent operation.

[0030] For example, such as Figure 1 As shown, the lower pressure plate 3-3 and the support frame 3-5 are in close contact. The support frame 3-5 is located on opposite sides of the lower pressure plate 3-3. The lower end face of the processing frame 1 is provided with a mounting frame 6, which is movably connected to the push rod 4-2.

[0031] In some examples, the mounting frame 6 is used to fix the push rod 4-2 and ensure that the extension and retraction direction of the push rod 4-2 is stable; the end of the push rod 4-2 is connected to the push frame 4-3, and the side wall of the push frame 4-3 is connected to the sliding piece 4-4. The function of the push rod 4-2 is to drive the sliding piece 4-4 and the forming plate 2 to move through the push frame 4-3, so as to achieve precise positioning of the forming plate 2.

[0032] In use, start the lifting rod 3-1. The lifting rod 3-1 drives the lower pressure plate 3-3 downward. Under the limiting action of the support frame 3-5, the lower pressure plate 3-3 maintains a vertical descent until the shaping strip 3-4 is fully embedded in the shaping groove 3-7. The shaping strip 3-4 and the shaping groove 3-7 work together to compress the straw fibers. By controlling the downward pressure of the lifting rod 3-1, the tightness of the straw fibers can be adjusted to regulate the straw fiber density. After adjustment, maintain the downward pressure for a period of time to allow the straw fibers to maintain a stable shape and prevent subsequent movement. When the position of the grass fibers changes during the forming disc 2, the push rod 4-2 is activated. The push rod 4-2 pushes the push frame 4-3 to move. The push frame 4-3 drives the sliding plate 4-4 to slide along the limiting clamp 4-6. At the same time, the sliding plate 4-4 drives the forming disc 2 to move within the sliding track 4-1 through the sliding wheel, precisely moving the forming disc 2 to directly below the feeding disc 3-6. At this time, the bottom of the grass fibers is completely inside the forming disc 2. The push rod 4-2 stops running to ensure that the position of the forming disc 2 is fixed and to prevent displacement when injecting hot melt material later.

[0033] Inject hot melt material (such as hot melt adhesive) into the forming disc 2. As the bearing component of the hot melt material, the forming disc 2 must be free of impurities to avoid affecting the hot melt effect. During the injection process, adjust the amount of hot melt material injected according to the density of the grass fibers. When the grass fiber density is high, increase the injection amount appropriately to ensure that the hot melt material can fully cover the bottom of the grass fibers; when the density is low, reduce the injection amount to avoid material waste. After the injection is completed, check the distribution of the hot melt material in the forming disc 2 to ensure that the material evenly covers the area where the bottom of the grass fibers is located.

[0034] Maintain a stable temperature of the hot melt material in the forming disc 2, allowing the bottom of the grass fibers to be completely immersed in the hot melt material. During this process, the hot melt material gradually penetrates into the fiber gaps at the bottom of the grass fibers. Through continuous heat action, the bottom of the grass fibers and the hot melt material are fully fused together to form an integral structure. During this period, the position of the forming disc 2 must be kept fixed and movement is prohibited to prevent the bottom of the fused grass fibers from breaking or becoming uneven.

[0035] After the bottom of the grass fibers is completely fused with the hot melt material, stop heat preservation of the hot melt material and allow the hot melt material in the forming tray 2 to cool naturally. During the cooling process, the hot melt material gradually solidifies, firmly fixing the bottom of the grass fibers together to form a stable integrated structure. The cooling time must ensure that the hot melt material is completely solidified to prevent the bottom of the grass fibers from falling off during subsequent operations.

[0036] Start the push rod 4-2, which drives the sliding plate 4-4 to move along the limiting clamp 4-6. The cutting plate 4-5 at the end of the sliding plate 4-4 slides against the upper surface of the feeding tray 3-6, cutting the fused and shaped grass fibers from the bottom. During the cutting process, the limiting clamp 4-6 ensures that the sliding plate 4-4 moves in a stable direction, making the cutting position neat and without burrs. After the cutting is completed, start the push rod 4-2 in the opposite direction, which drives the forming tray 2 to reset along the sliding track 4-1. Then, take out the cut grass fiber finished product.
