Description

Technical Field

[0001] This utility model relates to the field of artificial turf processing technology, specifically to a traction mechanism for an artificial turf tufting machine. Background Technology

[0002] Artificial turf tufting machine is the core equipment for producing artificial turf. Its traction mechanism, as a key component, is mainly used for precise and stable intermittent conveying of the base fabric during the tufting process. According to CN220520819U, a traction device for an artificial turf tufting machine is disclosed. This technology discloses a technical solution including "a base, an adjustment component, and a winding and pressing component, wherein the adjustment component is located on one side of the base, and the winding and pressing component is located on one side of the adjustment component". It has technical effects such as "the traction part adopts a rubber wheel: this wheel not only has good traction performance, but also can prevent damage to the turf". Existing traction mechanisms typically use rigid mounting for cleaning, which cannot adapt to dimensional changes caused by the movement or wear of the traction roller surface. This can lead to gaps or excessive contact between the dust collection components and the roller surface, resulting in unstable dust collection, incomplete cleaning, or increased mechanical wear. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a traction mechanism for an artificial turf tufting machine. By elastically pressing the dust suction cylinder against the staggered adsorption holes, it achieves efficient and continuous cleaning, effectively prevents the accumulation of impurities, and ensures traction accuracy and stable product quality.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a traction mechanism for an artificial turf tufting machine, comprising a traction mechanism for conveying and cleaning the base fabric, the traction mechanism comprising: The main component includes two side frames arranged symmetrically on the left and right, with a traction roller rotatably mounted between the two side frames, and a geared motor mounted on the outer wall of the side frame for driving the traction roller to rotate; The vacuuming assembly includes a shaft arm that is rotatably mounted on the inner wall of the side frame via a pivot, a protruding rod that is fixed to the inner wall of the side frame, a tension spring that connects the protruding rod to the lower end of the shaft arm, and a vacuuming cylinder that is provided at the upper end of the shaft arm. The dust removal assembly is mounted on the main assembly and is used to brush off impurities from the surface of the traction roller.

[0005] Preferably, the dust collection cylinder includes a cylinder body rotatably mounted between the upper ends of the two side shaft arms, and the cylinder body is located below the front end of the traction roller. The cylinder body has a plurality of waist-shaped dust collection holes arranged in an array, and the waist-shaped dust collection holes are staggered among each other.

[0006] Preferably, the vacuum cleaner also includes a beveled edge on the outer edge of the waist-shaped vacuum hole opened on the cylinder.

[0007] Preferably, the vacuum cleaner also includes a rotary joint rotatably mounted at one end of the cylinder, and the other end of the rotary joint is connected to a vacuuming device.

[0008] Preferably, the dust removal assembly includes a crossbeam fixed between the two side frames, a receiving cover is installed at the upper end of the crossbeam and the receiving cover is located directly below the traction roller, and a brush head is fixed inside the upper end of the receiving cover.

[0009] Preferably, the main body component further includes a support arm pivotally connected to the inner wall of the side frame, a pressure roller is rotatably installed between the upper ends of the two support arms, and the pressure roller is located above the front end of the traction roller. A cylinder is pivotally connected to the inner wall of the side frame, and the output end of the cylinder is pivotally connected to the middle of the support arm. Beneficial effects

[0010] This invention provides a traction mechanism for an artificial turf tufting machine. Compared with the prior art, it has the following advantages: 1. The traction roller is driven by a geared motor to achieve precise intermittent conveying of the base fabric. Simultaneously, the tension of the spring causes the shaft arm to rotate around the pivot, keeping the dust collection cylinder elastically pressed against the surface of the traction roller. The elastic deformation of the spring automatically compensates for minor runouts, manufacturing errors, or diameter changes on the surface of the traction roller. This ensures that the dust collection cylinder maintains the optimal contact distance with the roller surface to guarantee a stable and efficient negative pressure field at the suction holes, and also buffers against mechanical damage to the roller surface or itself caused by rigid contact. This improves the reliability and continuity of the dust collection operation, allowing it to adapt to changes in operating conditions over long periods without frequent manual adjustments. This ensures efficient removal of impurities and effectively prevents the accumulation of dust and debris from negatively impacting traction accuracy and product quality.

[0011] 2. When the cylinder comes into contact with the traction roller surface, it can rotate passively. The array of staggered waist-shaped dust suction holes on the cylinder surface forms a continuous negative pressure coverage area without dead zones, which significantly expands the effective adsorption area. At the same time, the waist-shaped long hole structure is less likely to be completely blocked by fibrous impurities than round holes. Even if some hole sections are covered, the rest can still maintain the adsorption function. This achieves efficient, continuous and stable suction of impurities and improves cleaning efficiency.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a traction mechanism for an artificial turf tufting machine, including a traction mechanism 1 for conveying and cleaning the base fabric, the traction mechanism 1 including: The main component 11 includes two side frames 111 arranged symmetrically on the left and right, a traction roller 112 is rotatably mounted between the two side frames 111, and a reduction motor 113 is mounted on the outer wall of the side frame 111 to drive the traction roller 112 to rotate. The vacuuming assembly 12 includes a shaft arm 122 rotatably mounted on the inner wall of the side frame 111 via a pivot 121, a protruding rod 123 fixed on the inner wall of the side frame 111, a tension spring 124 connecting the protruding rod 123 and the lower end of the shaft arm 122, and a vacuuming cylinder 125 provided at the upper end of the shaft arm 122. Dust removal assembly 13 is disposed on main assembly 11 and is used to brush off impurities from the surface of traction roller 112.

[0016] In this embodiment, the traction roller 112 is driven to rotate by the geared motor 113, achieving precise intermittent conveying of the base fabric. Simultaneously, the tension of the tension spring 124 causes the shaft arm 122 to rotate around the rotating shaft 121, driving the dust collection cylinder 125 to always elastically press against the surface of the traction roller 112. The elastic deformation of the tension spring 124 automatically compensates for minor runouts, manufacturing errors, or diameter changes on the surface of the traction roller 112, ensuring that the dust collection cylinder 125 not only maintains the optimal contact distance with the roller surface to ensure a stable and efficient negative pressure field at the dust collection hole, but also buffers and avoids mechanical damage to the roller surface or itself caused by rigid contact. This improves the reliability and continuity of the dust collection operation, allowing it to adapt to changes in operating conditions during long-term operation without frequent manual adjustments, thereby ensuring efficient removal of impurities and effectively preventing the negative impact of dust and waste accumulation on traction accuracy and product quality.

[0017] Specifically, the dust collection cylinder 125 includes a cylinder 1251 rotatably mounted between the upper ends of the two side shaft arms 122, and the cylinder 1251 is located below the front end of the traction roller 112. The cylinder 1251 has a plurality of waist-shaped dust collection holes 1252 arranged in an array, and the waist-shaped dust collection holes 1252 are staggered among each other.

[0018] In this embodiment, the cylinder 1251 can passively rotate when it comes into contact with the surface of the traction roller 112. The waist-shaped dust collection holes 1252 arranged in an array on the surface of the cylinder 1251 form a continuous negative pressure coverage area without dead zones, which significantly expands the effective adsorption area. At the same time, the waist-shaped elongated hole structure is less likely to be completely blocked by fibrous impurities than round holes. Even if some hole sections are covered, the remaining parts can still maintain the adsorption function. This achieves efficient, continuous and stable suction of impurities, improving cleaning efficiency.

[0019] Specifically, the vacuum cleaner 125 also includes a beveled edge 1253 on the outer edge of the waist-shaped vacuum hole 1252 opened on the cylinder body 1251.

[0020] In this embodiment, by setting a bevel 1253 on the outer edge of the waist-shaped dust suction hole 1252, a smooth transition guide structure is formed. When impurities approach the dust suction hole with the airflow, the bevel 1253 can effectively guide the impurities smoothly into the cylinder 1251, reducing the risk of fibrous waste and adhesive particles getting stuck and blocked at the edge of the hole.

[0021] Specifically, the vacuum cleaner 125 also includes a rotary joint 1254 rotatably mounted on one end of the cylinder 1251, and the other end of the rotary joint 1254 is connected to a vacuuming device.

[0022] In this embodiment, when the cylinder 1251 rotates, it is connected to a vacuum cleaner through a rotary joint 1254 to ensure that the negative pressure suction force acts continuously and stably inside the cylinder 1251.

[0023] Specifically, the dust removal assembly 13 includes a crossbeam 131 fixed between the two side frames 111. A receiving cover 132 is installed on the upper end of the crossbeam 131, and the receiving cover 132 is located directly below the traction roller 112. A brush head 133 is fixed inside the upper end of the receiving cover 132.

[0024] In this embodiment, when the traction roller 112 rotates, the brush head 133 actively removes impurities such as waste filaments and rubber particles embedded in the roller surface by scraping, causing them to peel off and fall into the receiving cover 132. At the same time, the dust suction cylinder 125 instantly sucks in the light dust, debris and other impurities that are suspended in the air after being brushed, avoiding secondary pollution of impurities.

[0025] Specifically, the main body component 11 also includes a support arm 114 pivotally connected to the inner wall of the side frame 111. A pressure roller 115 is rotatably installed between the upper ends of the two support arms 114, and the pressure roller 115 is located above the front end of the traction roller 112. A cylinder 116 is pivotally connected to the inner wall of the side frame 111, and the output end of the cylinder 116 is pivotally connected to the middle of the support arm 114.

[0026] In this embodiment, the cylinder 116 pushes the middle part of the support arm 114 through the output end, causing the support arm 114 to rotate around the pivot point, thereby precisely controlling the pressing and separating of the pressing roller 115 relative to the traction roller 112; when the cylinder 116 extends, the pressing roller 115 presses tightly onto the base fabric at the front end of the traction roller 112 with adjustable pressure, forming a stable clamping force.

[0027] The working principle and usage process of this utility model are as follows: First, the traction roller 112 is driven to rotate by the reduction motor 113 to achieve precise intermittent conveying of the base fabric; then, the cylinder 116 pushes the middle of the support arm 114 through the output end, causing the support arm 114 to rotate around the pivot point, thereby precisely controlling the pressing roller 115 relative to the traction roller 112 in pressing and separating; when the cylinder 116 extends, the pressing roller 115 presses the base fabric at the front end of the traction roller 112 with adjustable pressure, forming a stable clamping force; Meanwhile, the tension of the tension spring 124 causes the shaft arm 122 to rotate around the rotating shaft 121, causing the dust collection cylinder 125 to always elastically press against the surface of the traction roller 112. When the cylinder 1251 contacts the surface of the traction roller 112, it can passively rotate. The array of waist-shaped dust collection holes 1252 on the surface of the cylinder 1251 forms a continuous negative pressure coverage area without dead zones, which significantly expands the effective adsorption area. At the same time, the waist-shaped long hole structure is less likely to be completely blocked by fibrous impurities than round holes. Even if some hole sections are covered, the rest can still maintain the adsorption function. Furthermore, when the traction roller 112 rotates, the brush head 133 actively removes waste filaments, rubber particles and other impurities embedded in the roller surface by scraping, causing them to peel off and fall into the receiving cover 132. At the same time, the dust collection cylinder 125 instantly sucks in the light dust, debris and other impurities that are suspended in the air after being brushed, avoiding secondary pollution of impurities.
