Description

Technical Field

[0001] This application relates to the field of textile machinery and equipment, and in particular to a production equipment for agricultural coverings. Background Technology

[0002] Currently, some coverings, such as agricultural mulch materials, plastic film, frost protection cloth, reflective cloth, and weed control cloth, usually have multiple through holes or buckle structures around the edges of the covering for binding ropes. Then, the end of the rope away from the covering is fixed, thus covering the crops or other objects. The problem with this method is that binding the two ends of the rope is relatively troublesome and requires a high level of hand strength from the operator. The rope binding connection must be reliable and stable, otherwise the rope will easily become loose and cause the covering to shift in the wind. Moreover, the most troublesome and unsolvable problem is that the structural strength of the through holes or the connection strength between the buckle structure and the covering is limited. If a strong wind is encountered, the through holes are easily torn by the rope, and the buckle structure is easily separated from the covering.

[0003] To address these issues, some agricultural mulch materials are now directly bonded or sewn to the rope fabric during production. This solves the problems of through holes being easily torn by the rope and buckle structures easily separating from the mulch material. Moreover, when using agricultural mulch materials in the future, only one end of the rope fabric needs to be tied and secured, which is very convenient.

[0004] Currently, the working principle of equipment that directly bonds agricultural mulch to rope fabric during production is generally to automatically transport the rope fabric to the mulch to be bonded, and then use ultrasonic welding for pressing. For example, as shown in patent publication number CN212219335U, although the patent shows the pressing and welding of mask ear loops to mask fabric, its principle is the same as that of equipment that bonds agricultural mulch to rope fabric.

[0005] Although the built-in ropes in agricultural mulch save time and make the mulching process simple and convenient, the rope fabric and mulch are only simply connected by ultrasonic pressing and welding due to limitations in the bonding method and equipment. The connection strength is limited, and the two can still separate in extreme windy weather. Utility Model Content

[0006] To address the problem of limited connection strength in current equipment for bonding agricultural coverings to rope fabrics, this application provides a production device for agricultural coverings.

[0007] The production equipment for agricultural coverings provided in this application adopts the following technical solution: A production device for agricultural mulch includes a pressing unit and a waist rope conveying unit. The waist rope conveying unit is used to convey waist ropes to the pressing unit, and the pressing unit is used to convey the mulch and press and weld the waist ropes to the mulch. The waist rope conveying unit has at least a welding and folding mechanism. The welding and folding mechanism folds and welds the rope to form a waist rope. The welding and folding mechanism includes a folding device and a welding device arranged sequentially along the rope movement direction. The folding device is used to guide the two sides of the rope in the wide belt direction to bend towards the center line of the rope, thereby forming a folded part on each side of the rope in the wide belt direction. The welding device is used to weld and fix the folded part to the rope. The pressing unit has at least: A conveyor roller assembly 1 is used to convey a cover along its own length and to flatten the cover, and includes a frame and at least two rollers mounted on the frame; A rope-pulling mechanism for pulling a waist rope from one side to the other in the width direction of the cover includes a reciprocating translation device, a pair of clamps, and a lifting device 1 connected to the reciprocating translation device. The pair of clamps are spaced apart vertically. One clamp is connected to the reciprocating translation device, and the other clamp is connected to the movable end of the lifting device 1. The waist rope extends between the pair of clamps, and the lifting device 1 pushes the pair of clamps closer together to clamp the waist rope. Several welding mechanisms are arranged at intervals along the width of the cover to press and weld rope segments to the cover. The rope segments are formed by moving the waist rope from one side of the width of the cover to the other side and then cutting off the waist rope on one side of the width of the cover. At least two rope pressing mechanisms are located below both ends of the rope segment. Each rope pressing mechanism includes a push-pull device and a rope carrier seat connected to the movable end of the push-pull device. After the rope segment separates from the clamp, it falls onto the rope carrier seat. The push-pull device pushes the rope segment on the rope carrier seat to move closer to the welding mechanism, and the welding mechanism presses and welds the rope segment to the cover.

[0008] In summary, this application includes at least one of the following beneficial technical effects: 1. The covering produced by the production equipment of this application comes with a waist rope, which eliminates the trouble of tying ropes to the covering during use. Moreover, a certain width of fabric is folded and pressed to form a flat waist rope, and then the waist rope is fixed to the fabric by pressing and welding the fabric. The folding and pressing of the fabric for the rope and welding it to the covering greatly improves the connection strength between the two. The waist rope and the covering have a high connection strength, and even in strong winds, the waist rope is not easy to separate from the covering.

[0040] The following is in conjunction with the appendix Figures 1-32 This application is further described in detail below. Figures 1-32 The middle arrow indicates the direction of transport for the waist rope 6 or the covering.

[0041] This application discloses a production device for agricultural coverings. (Refer to...) Figure 1 and Figure 8 As shown, the production equipment for agricultural mulch includes at least a pressing unit 2 and a waist rope conveying unit 3. The waist rope conveying unit 3 is used to convey the waist rope 6 to the pressing unit 2, eliminating the trouble of manually laying the waist rope 6 on the mulch, realizing automatic conveying of the waist rope 6, with a high degree of automation, fast production speed, low production cost, and enhanced enterprise competitiveness. The pressing unit 2 is used to convey the mulch and press and weld the waist rope 6 to the mulch, thereby obtaining a mulch with waist rope 6. Such a mulch eliminates the trouble of tying ropes to the mulch for use in the future. Moreover, after a certain width of fabric is folded and pressed to form a flat waist rope 6, and then combined with fabric pressing and welding, the waist rope 6 is fixed to the fabric. The folding and pressing of the rope fabric and then welding it to the mulch greatly improves the connection strength between the two. The waist rope 6 has a high connection strength with the mulch, and even in strong winds, the waist rope is not easy to separate from the mulch. Furthermore, the agricultural mulch production equipment of this embodiment can automatically press and bond the waist rope 6 to the mulch, and bond a waist rope 6 at intervals along the length of the mulch to ensure that the waist rope 6 can securely and stably cover the crops or other objects under strong winds, and the waist rope 6 is not easy to separate from the mulch.

[0042] Specifically, such as Figure 2 As shown, the waist rope conveying unit 3 has at least a welding and folding mechanism 34, which folds and welds the rope 61 to form the waist rope 6, as shown. Figure 5 and Figure 6 As shown, the welding and folding mechanism 34 includes at least a folding device 340 and a welding device arranged sequentially along the moving direction of the rope 61. The folding device 340 is used to guide both sides of the rope 61 in the wide width direction to bend towards the centerline of the rope 61, thereby forming a folded edge 62 on each side of the rope 61 in the wide width direction. Figure 7 As shown. The welding device is used to weld and fix the folded edge 62 to the rope 61.

[0043] In this embodiment, the welding device is one of the following: ultrasonic welding device, high-frequency welding device (such as radio frequency welding device), hot air welding device (such as hot press welding device), laser welding device, and wear-resistant surfacing welding device (such as metal-based fabric chute welding device). Preferably, the welding device is an ultrasonic welding device.

[0044] In this embodiment, as Figure 5 and Figure 6 As shown, when the welding device is an ultrasonic welding device, it includes at least an ultrasonic head 348 and a flower wheel 346, which are arranged vertically at intervals, and a rope 61 passes between the ultrasonic head 348 and the flower wheel 346.

[0045] In this embodiment, the welding and folding mechanism 34 is designed in a modular fashion to facilitate future maintenance, such as... Figure 5 and Figure 6 As shown, the welding and folding mechanism 34 also has a frame 341, on which the folding device 340 and the welding device 341 are mounted. Further, the welding device 341 includes a bearing 345, a lifting device 344, a mounting block 343, a mounting shaft 342, and a drive device 347. The mounting shaft 342 is rotatably mounted on the frame 341. The mounting block 343 and bearing 345 are fixedly connected to the mounting shaft 342. The flower wheel 346 is rotatably mounted on the bearing 345. The drive device 347... 47 is fixedly installed on frame 7 341 and is connected to the flower wheel 5 346 for driving the flower wheel 5 346 to rotate. The lifting device 2 344 is hinged to frame 7 341. The movable end of the lifting device 2 344 is hinged to the mounting block 343. The action of the lifting device 2 344 drives the mounting shaft 342 to rotate through the mounting block 343, which in turn drives the shaft seat 345 and the flower wheel 5 346 to rotate around the mounting shaft 342 to adjust the distance between the flower wheel 5 346 and the ultrasonic mold head 5 348 and control the welding action of the welding device 1.

[0046] In this embodiment, as Figure 5 and Figure 6 As shown, the welding and folding mechanism 34 also has a guide roller group 349, which is connected to the drive device 347. The drive device 347 drives the guide roller group 349 to rotate actively to guide and convey the waist rope 6, flattening the waist rope 6 and ensuring that the waist rope 6 meets the requirements for subsequent welding with the covering.

[0047] In this embodiment, as Figure 2 As shown, the waist rope conveying unit 3 further includes a pressing mechanism 33, which is used to press the multiple layers of rope 61 together, for example... Figure 7The waist rope 6 shown has two layers of rope straps 61. This waist rope 6 has multiple layers of rope straps 61, which improves the tensile strength of the waist rope 6 and effectively prevents the waist rope 6 from breaking.

[0048] In this embodiment, as Figure 3 and Figure 4 As shown, the pressing mechanism 33 has at least multiple sets of conveying roller groups 332 and guide roller groups. Each layer of rope 61 is conveyed and guided by a set of conveying roller groups 332 and guide roller groups. Multiple sets of conveying roller groups 332 and guide roller groups guide the multiple layers of rope 61 to be gradually pressed together.

[0049] To facilitate future maintenance and repair, the pressing mechanism 33 is designed in a modular fashion. Figure 3 and Figure 4 As shown, the pressing mechanism 33 has a frame 331, and multiple sets of conveyor rollers 332 and guide rollers are mounted on the frame 331. Taking a waist rope 6 with two layers of ropes 61 as an example, Figure 3 and Figure 4 As shown, there are two sets of conveyor rollers 332. The guide roller set includes one set of guide rollers 334, two sets of guide rollers 336, and two guide shafts 337. Each rope 61 passes through a guide shaft 337, a set of guide rollers 336, and a set of conveyor rollers 332 in sequence along the conveying direction. The two ropes 61 are pressed together at the two sets of conveyor rollers 332, and then conveyed to the welding and folding mechanism 34 through the guide rollers 334.

[0050] In this embodiment, as Figure 3 and Figure 4 As shown, the frame 631 is equipped with a material detection device 335, which is used to detect whether there is a rope 61 on the guide roller group, so as to remind the staff to replenish the material on the rope 61 in a timely manner. Common material detection devices 335 include detection elements such as position sensors, laser sensors, and photoelectric switches.

[0051] In this embodiment, as Figure 3 and Figure 4 As shown, a lifting device 333 is also installed on the frame 6 331. The movable end of the lifting device 333 is connected to the conveyor roller group 332. The lifting device 333 drives the conveyor roller group 332 to move up and down to tighten the loose rope 61.

[0052] To facilitate future maintenance and repair, the waist rope transmission unit 3 is designed in a modular fashion. Figure 2 As shown, the waist rope conveying unit 3 has a frame 31, and the pressing mechanism 33 and the welding and folding mechanism 34 are both mounted on the frame 31. Further, as... Figure 2As shown, the frame 31 is also equipped with a reel 32 and a leveling roller group. The rope 61 is wound on the reel 32 and stored in a roll. When in use, the reel 32 can be directly installed on the frame 31. After the rope 61 on the reel 32 is unrolled, it enters the pressing mechanism 33 and the welding and folding mechanism 34 in sequence. The waist rope 6 that leaves the welding and folding mechanism 34 enters the leveling roller group for secondary leveling to ensure that it meets the welding requirements of the subsequent covering. The leveling roller group is composed of multiple leveling rollers 35.

[0053] Specifically, such as Figures 14-23 As shown, the pressing unit 2 includes at least: a conveyor roller assembly 29, a rope guiding mechanism 24, several welding mechanisms 28, and at least two rope pressing mechanisms 26. The conveyor roller assembly 29 is used to transport the covering material along its own length and flatten the covering material for subsequent pressing and welding with the waist rope 6, ensuring welding quality. The conveyor roller assembly 29 includes a shaft frame 21 and at least two shaft rollers mounted on the shaft frame 21, for example... Figure 20 and Figure 22 As shown, the at least two rollers are the third roller 293 and the fourth roller 294. The third roller 293 and the fourth roller 294 convey the covering material and flatten it so that the covering material has a flat surface, so as to press and weld it with the waist rope 6 and ensure the welding quality.

[0054] In this embodiment, further, such as Figure 20 and Figure 22 As shown, the roller also includes a first roller 291, a second roller 292, and a fifth roller 295. The first roller 291, the second roller 292, and the fifth roller 295 are used to guide and transport the covering material, so that the covering material can smoothly pass through the pressing unit 2 and be pressed and welded to the waist rope 6. Specifically, the covering material enters the pressing unit 2 through the first roller 291, and then passes through the second roller 292, the third roller 293, and the fourth roller 294 in sequence, and finally leaves the pressing unit 2 from the fifth roller 295. The covering material completes the pressing and welding with the waist rope 6 between the third roller 293 and the fourth roller 294.

[0055] In this embodiment, the rope-guiding mechanism 24 is used to pull the waist rope 6 from one side to the other in the width direction of the covering, such as... Figure 1 , Figure 2 and Figure 15 As shown, the waist rope 6 output from the leveling roller group of the waist rope conveying unit 3 enters the pressing unit 2 and is clamped and pulled by the rope guiding mechanism 24 to move the waist rope 6 from one side to the other side in the width direction of the cover.

[0056] Specifically, such as Figures 14-17As shown, the rope guiding mechanism 24 includes a reciprocating translation device, a pair of clamping plates 245, and a lifting device 244 connected to the reciprocating translation device. The reciprocating translation device drives the pair of clamping plates 245 and the lifting device 244 to reciprocate along both sides of the width direction of the covering, continuously moving the waist rope 6 from one side to the other in the width direction of the covering. Commonly, the reciprocating translation device is any one of a linear motor, cylinder, hydraulic cylinder, or conveyor. The conveyor includes common linear conveying equipment such as belt conveyors, plate conveyors, and chain conveyors. Figure 15 and Figure 17 The reciprocating translation device shown is a belt conveyor, which includes a drive unit 241, a transmission belt 242, and a mounting frame 243. The drive unit 241 is mounted on a shaft frame 21. A pulley 122 is provided on each side of the shaft frame 21 in the width direction of the cover. The two pulleys 122 are connected by the transmission belt 242. The mounting frame 243 is slidably connected to the shaft frame 21 and fixedly connected to the transmission belt 242. The drive unit 241 drives the transmission belt 242 to drive the mounting frame 243 to slide on the shaft frame 21. The sliding direction is from one side of the width direction of the cover to the other side.

[0057] In this embodiment, as Figure 15 As shown, a pair of clamping plates 245 are arranged at intervals. One clamping plate 245 is fixedly connected to the mounting bracket 243, and the other clamping plate 245 is connected to the movable end of the lifting device 244. The waist rope 6 extends between the pair of clamping plates 245. The lifting device 244 pushes the pair of clamping plates 245 closer together to clamp the waist rope 6. Then, the reciprocating translation device pulls the waist rope 6 from one side to the other side in the width direction of the cover through the pair of clamping plates 245.

[0058] In this embodiment, after the pair of clamping plates 245 pull the waist rope 6 from one side of the cover width direction to the other side, the waist rope 6 on one side of the cover width direction needs to be cut to form a rope segment 63. Subsequently, the rope segment 63 is pressed and welded to the cover. After the pair of clamping plates 245 pull the waist rope 6 from one side of the cover width direction to the other side, the lifting device 244 drives the pair of clamping plates 245 to move away from each other and loosen the clamping of the waist rope 6. After the rope segment 63 separates from the clamping plates 245, the reciprocating translation device drives the pair of clamping plates 245 back to the original position. Figure 15 Clamp one end of the waist rope 6 again at the indicated position, and then repeat the aforementioned action to continuously feed the rope segment 63 onto the cover.

[0059] In this embodiment, cutting the waist rope 6 on one side of the covering width direction can be done manually or as follows: Figure 15 As shown, an automatic scissor 23 is installed on one side of the width direction of the covering. The automatic scissor 23 automatically cuts the waist rope 6, thereby improving the automation level of the covering production equipment.

[0060] The automatic scissors 23 can, as Figure 15 The automatic scissors 23 can be set on the shaft frame 21 as shown, or it can be set next to the leveling roller group in the waist rope conveying unit 3. The power source of the automatic scissors 23 can be pneumatic, hydraulic or electric.

[0061] In this embodiment, to prevent the waist rope 6 from shifting or deviating after it is cut, thus causing the subsequent pair of clamps 245 to return to one side of the width direction of the cover and fail to clamp one end of the traction waist rope 6, as follows: Figure 15 As shown, a rope threader 25 is provided on one side of the covering in the width direction. The waist rope 6 passes through the rope threader 25 and extends between a pair of clamping plates 245. The rope threader 25 includes a rope carrier plate 251 and a pressure block 252 disposed on the upper surface of the rope carrier plate 251. The waist rope 6 passes between the rope carrier plate 251 and the pressure block 252. When the waist rope 6 on one side of the covering in the width direction is cut, the end of the newly formed waist rope 6 is pressed and fixed on the rope carrier plate 251 by the pressure block 252 to prevent one end of the waist rope 6 from shifting or deviating. Moreover, the end of the newly formed waist rope 6 can move relative to the reciprocating translation device and extend between a pair of clamping plates 245. That is, when the pair of clamps 245 return to one side of the width direction of the cover, they can continue to clamp one end of the traction waist rope 6, so as to prevent the newly formed end of the waist rope 6 from leaving the working position after the waist rope 6 is cut, which would cause the pair of clamps 245 to be unable to clamp the end of the waist rope 6 after returning to the initial position. The pressure block 252 is slidably installed on the rope carrying plate 251 and has a certain weight. When the pair of clamps 245 are not pulling the waist rope 6, the end of the waist rope 6 is pressed down by the pressure block 252 and cannot move randomly. When the pair of clamps 245 pull the waist rope 6, the waist rope 6 overcomes the frictional resistance of the pressure block 252 and slides between the rope carrying plate 251 and the pressure block 252.

[0062] In this embodiment, the automatic scissors 23 can be fixed to the shaft frame 21 or slidably mounted on the shaft frame 21, as long as it does not affect the clamping of the waist rope 6 by the pair of clamping plates 245 and the cutting of the waist rope 6. When the automatic scissors 23 is slidably mounted on the shaft frame 21, its sliding direction can be either along the length direction of the waist rope 6 or along the width direction of the waist rope 6.

[0063] In this embodiment, further, such as Figure 15 As shown, a guide roller assembly 22 is also provided on one side of the width direction of the covering. The waist rope 6 is guided into the pressing unit 2 by the guide roller assembly 22, so that the waist rope 6 can pass through the rope threader 25. The waist rope 6 output from the waist rope conveying unit 3 enters the pressing unit 2 from the guide roller assembly 22, and then passes through the rope threader 25 and the automatic scissors 23 in sequence before extending between a pair of clamps 245.

[0064] In this embodiment, the movement of the rope 61 in the waist rope conveying unit 3 is driven by the driving device 347, and the movement of the waist rope 6 in the waist rope conveying unit 3 is driven by the reciprocating translation device. Of course, in other embodiments, the movement of the rope 61 and the waist rope 6 can also be driven by the reciprocating translation device, or a driving device can be independently set between the waist rope conveying unit 3 and the pressing unit 2 to drive the movement of the waist rope 6 and / or the rope 61 in the waist rope conveying unit 3.

[0065] In this embodiment, when the lifting device 244 is driven by a pneumatic cylinder or a hydraulic cylinder, it also has a control valve 246 for adjusting the pressure of the air circuit or oil circuit, thereby controlling the action of the pneumatic cylinder or the hydraulic cylinder.

[0066] Specifically, such as Figure 16 As shown, several welding mechanisms 28 are arranged at intervals along the width direction of the cover. Preferably, several welding mechanisms 28 are arranged at equal intervals. The welding mechanism 28 is used to press and weld the rope segment 63 to the cover. The rope segment 63 is formed by cutting the waist rope 6 on one side of the width direction of the cover after the waist rope 6 moves from one side to the other side. Multiple welding mechanisms 28 ensure that the waist rope 6 and the cover have high connection strength. Even if it is subjected to strong winds, the waist rope 6 is not easy to separate from the cover.

[0067] The welding mechanism 28 is one of the following: ultrasonic welding device, high frequency welding (such as radio frequency welding) device, hot air welding (such as hot press welding) device, laser welding device, and wear-resistant overlay welding (such as metal-based fabric chute welding) device. Preferably, the welding mechanism 28 is an ultrasonic welding device. Ultrasonic welding is fast, efficient, does not require needles or thread, produces a smooth welded surface without burrs, and has a good feel.

[0068] Specifically, when the welding mechanism 28 is an ultrasonic welding device, such as... Figure 17 , Figure 21 , Figure 23 As shown, a single welding mechanism 28 includes: a second lifting device 281, a first transmission mechanism 27, a first pattern wheel 283 and an ultrasonic mold head 284 arranged vertically at intervals. The first pattern wheel 283 is rotatably mounted on a second wheel seat 282. The covering material passes between the first pattern wheel 283 and the first ultrasonic mold head 284. The second lifting device 281 is mounted on a shaft frame 21. The second lifting device 281 connects the second wheel seat 282 and / or the first ultrasonic mold head 284, and is used to drive the first pattern wheel 283 and / or the first ultrasonic mold head 284 to rise and fall relative to the covering material, for example... Figure 17 , Figure 21 , Figure 23 The ultrasonic transducer head 284 is fixed on the shaft bracket 21, and the lifting device 281 is only used to drive the flower wheel 283 to rise and fall. The transmission mechanism 27 is connected to the flower wheel 283 and is used to drive the flower wheel 283 to rotate, for example... Figure 17 , Figure 21 , Figure 23 The transmission mechanism 27 shown includes a drive unit 271, a wheel axle 272, and a transmission belt 273. The drive unit 271 drives the wheel axle 272 to rotate, and the wheel axle 272 drives the flower wheel 283 to rotate via the transmission belt 273. The wheel axle 272 is rotatably mounted on the shaft frame 21, and the drive unit 271 is fixedly mounted on the shaft frame 21. Of course, in other embodiments, the specific transmission form used by the transmission mechanism 27 to drive the flower wheel 283 to rotate can also be a conventional transmission form such as gear transmission or chain transmission, or the transmission mechanism 27 can use a motor to directly drive the flower wheel 283 to rotate without transmitting power through the transmission belt.

[0069] The rope pressing mechanism 26 is used to push the rope segment 63 to move closer to the welding mechanism 28. The movement of the rope segment 63 to the welding mechanism 28 under the push of the rope pressing mechanism 26 includes the rope segment 63 moving between the flower wheel 283 and the cover or between the ultrasonic head 284 and the cover. Specifically, when the lifting device 281 is only used to drive the flower wheel 283 to rise and fall, the rope segment 63 is moved between the flower wheel 283 and the cover. When the lifting device 281 is only used to drive the ultrasonic head 284 to rise and fall, the rope segment 63 is moved between the ultrasonic head 284 and the cover. With this design, after the rope segment 63 moves closer to the welding mechanism 28 under the push of the rope pressing mechanism 26, the lifting device 281 pushes the flower wheel 283 or the ultrasonic head 284 to move closer to the cover, which can press the rope segment 63 tightly onto the cover, and then weld the rope segment 63 to the cover.

[0070] The rope pressing mechanism 26 is used to push the rope segment 63 to move closer to the welding mechanism 28. Therefore, in order to push the rope segment 63 to move closer to the welding mechanism 28, there are at least two rope pressing mechanisms 26, which are respectively located below both ends of the rope segment 63. When there are multiple rope pressing mechanisms 26, they are arranged at intervals along the width direction of the cover.

[0071] Specifically, such as Figure 19 , Figure 21 and Figure 23As shown, a single rope pressing mechanism 26 includes a push-pull device 262 and a rope carrier 263 connected to the movable end of the push-pull device 262. After the rope segment 63 separates from the clamping plate 245, the rope segment 63 falls onto the rope carrier 263. The push-pull device 262 pushes the rope segment 63 on the rope carrier 263 to move closer to the welding mechanism 28, and the welding mechanism 28 presses and welds the rope segment 63 to the covering. Furthermore, the single rope pressing mechanism 26 also includes a second push-pull device 266 and a pressure plate 265 connected to the second push-pull device 266. The second push-pull device 266 pushes the pressure plate 265 to move close to the rope carrier 263. The pressure plate 265, in cooperation with the rope carrier 263, clamps and fixes the rope segment 63 on the rope carrier 263. This prevents the rope segment 63 on the rope carrier 263 from moving away from the correct position relative to the rope carrier 263 during the process of the rope carrier 263 moving closer to the welding mechanism 28, which would affect the subsequent pressing and welding with the covering. This ensures that the first push-pull device 262 pushes the rope segment 63 on the rope carrier 263 to move stably and reliably closer to the welding mechanism 28 for pressing and welding with the covering. During the movement of the rope carrier 263, the rope segment 63 does not move or deviate on the rope carrier 263, ensuring that the subsequent welding operation can proceed normally.

[0072] In this embodiment, one specific form in which the push-pull device 266 pushes the pressure plate 265 to move close to the rope carrier seat 263 is as follows: Figure 19 , Figure 21 and Figure 23 As shown, the second push-pull device 266 is hinged to the first push-pull device 262 or the rope carrier 263. The pressure plate 265 is hinged to the second push-pull device 266 and the rope carrier 263. The second push-pull device 266 can push the pressure plate 265 to rotate on the rope carrier 263 until the pressure plate 265 is tightly pressed against the upper surface of the rope carrier 263, thereby pressing and fixing the waist rope 6 on the upper surface of the rope carrier 263. Of course, in other embodiments, the second push-pull device 266 can also push the pressure plate 265 to move to be tightly pressed against the rope carrier 263, or the second push-pull device 266 can drive the pressure plate 265 to move linearly or rotate closer to the rope carrier 263 to press and fix the waist rope 6 on the upper surface of the rope carrier 263.

[0073] In this embodiment, when the second push-pull device 266 is hinged to the first push-pull device 262 or the rope carrier 263, and the pressure plate 265 is hinged to the second push-pull device 266 and the rope carrier 263, and the second push-pull device 266 can push the pressure plate 265 to rotate on the rope carrier 263, to facilitate the installation of the second push-pull device 266 and the connection between the rope carrier 263 and the first push-pull device 262, as follows: Figure 19As shown, the rope support 263 includes a base plate 2631, a side plate 2632, and a baffle 2633. The baffle 2633 is fixedly connected to the base plate 2631. The movable end of the push-pull device 262 is connected to the baffle 2633. The baffle 2633 is vertically arranged on the upper surface of the base plate 2631. The base plate 2631 is horizontally arranged. After the rope segment 63 falls, it is located on the upper surface of the base plate 2631. The side plate 2632 is fixedly connected to the baffle 2633. The push-pull device 266 is hinged to the side plate 2632. The pressure plate 265 is hinged to the base plate 2631.

[0074] In this embodiment, further, such as Figure 19 As shown, a pressing groove 264 is provided on the base plate 2631. A portion of the rope segment 63 covers the pressing groove 264. When the push-pull device 262 pushes the rope segment 63 on the rope carrier 263 to move closer to the welding mechanism 28, the pressing groove 264 is located directly below the flower wheel 283 or directly above the ultrasonic mold head 284. Then, the flower wheel 283 descends or the ultrasonic mold head 284 rises, which can push the portion of the rope segment 63 covering the pressing groove 264 to press and weld tightly against the covering material.

[0075] In this embodiment, the push-pull device 262 can be directly fixedly connected to the shaft frame 21, or it can be fixedly connected to the shaft frame 21 via the frame 261. Preferably, the push-pull device 262 is fixedly connected to the frame 261, and the frame 261 is slidably fixedly connected to the shaft frame 21. The sliding direction is from one side of the width of the cover to the other side. This design makes it convenient to flexibly arrange the position of the rope pressing mechanism 26 according to the cover of different widths, and ensures that the rope pressing mechanism 26 can stably and reliably push rope segments 63 of different lengths to the cover of different widths.

[0076] As can be seen, the covering production equipment of this embodiment, composed of the waist rope conveying unit 3 and the pressing unit 2, can automatically press and bond the waist rope 6 to the covering. A waist rope 6 is bonded at regular intervals along the length of the covering to ensure that, even in strong winds, the waist rope 6 can reliably and securely cover crops or other objects. The covering produced by the equipment of this embodiment comes with a waist rope 6, eliminating the hassle of tying ropes to the covering during use. Furthermore, the connection strength between the waist rope 6 and the covering is high, and even in strong winds, the waist rope 6 is not easily separated from the covering.

[0077] In this embodiment, the production equipment for agricultural coverings further includes a folding and winding unit 4, which is used to fold and wind up the covering after the waist rope 6 output from the conveyor roller assembly 29 has been welded, thus eliminating the trouble of manual winding.

[0078] Specifically, such as Figure 1 , Figure 8 , Figures 11-13 As shown, the folding and winding unit 4 has a frame 41, which is directly or indirectly fixedly connected to the shaft frame 21. Figures 11-13 As shown, the frame 41 is equipped with a guide roller 42, a guide rod 43, an inverted triangular frame 44, a drive roller assembly 46, and a drive device 47. The guide roller 42 and the drive roller assembly 46 are rotatably mounted on the frame 41, while the guide rod 43 and the inverted triangular frame 44 are fixedly mounted on the frame 41. The guide roller 42 and the guide rod 43 are located on one side of the frame 41, and the inverted triangular frame 44 and the drive roller assembly 46 are located on the other side of the frame 41. The guide rod 43 is located above the guide roller 42 and is inclined. There is a pair of guide rods 43, preferably a pair of guide rods 43 symmetrically arranged above the guide roller 42. The axial direction of the guide roller 42 is parallel to the width direction of the covering, and the axial length of the guide roller 42 is less than the width of the covering. The lower ends of the pair of guide rods 43 are respectively located at the two axial ends of the guide roller 42 and do not contact the two axial ends of the guide roller 42. This design, as... Figure 11 As shown, the middle of the cover output by the conveyor roller assembly 29 passes over the guide roller 42, and the two sides of the cover in the width direction pass over a pair of guide rods 43, after which the two sides of the cover in the width direction fold towards the center line of the cover for one fold; as Figure 12 and Figure 13 As shown, the active roller group 46 is located below the inverted triangle frame 44 and is connected to the drive device 47. The drive device 47 drives the active roller group 46 to rotate. After the cover is folded once, it moves upward over the top of the frame 41 and then moves downward over the inverted triangle frame 44 before being folded a second time. The cover after the second fold moves under the traction of the active roller group 46. Correspondingly, the movement of the cover in the pressing unit 2 is also driven by the active roller group 46. Of course, in other embodiments, an active roller can also be set in the pressing unit 2 or between the pressing unit 2 and the folding and winding unit 4 to drive the movement of the cover in the pressing unit 2.

[0079] In this embodiment, further, such as Figures 11-13 As shown, the frame 41 is also equipped with a tension roller group 49, a guide roller group 5 48, a guide roller group 45, and a lifting device 40. The guide roller group 45 is located between the inverted triangle frame 44 and the active roller group 46. The cover after being folded twice and leaving the inverted triangle frame 44 is first guided and conveyed by the guide roller group 45 before entering the active roller group 46. After leaving the active roller group 46, the cover alternately passes through the tension roller group 49 and the guide roller group 5 48. The tension roller group 49 and the guide roller group 5 48 achieve the tensioning and conveying of the cover. One end of the tension roller group 49 is hinged to the frame, and the other end is connected to the lifting device 40. The lifting device 40 drives the tension roller group 49 to move relative to the guide roller group 5 48 to achieve the tensioning and conveying of the cover.

[0080] In this embodiment, as Figure 12 As shown, the two ends of the rope segment 63 on the cover output by the conveyor roller assembly 29 of the pressing unit 2 are suspended, which will cause the waist rope 6 to be exposed after the cover is folded, affecting the appearance. Therefore, the production equipment in this embodiment also has a folding device 7. The folding device 7 folds the two ends of the rope segment 63 on the cover to the top of the cover, so that the two ends of the rope segment 63 are no longer suspended. In this way, when the cover is folded, the rope segment 63 is wrapped up, and the folded cover has no rope segment 63 exposed, which is conducive to the neat and beautiful appearance of the cover.

[0081] Specifically, such as Figures 11-13 As shown, the folding device 7 has a guide rod 71, which is fixed above the folding portion 53 of the cover between the conveyor roller assembly 29 and the guide rod 43. For example, the guide rod 71 can be fixedly connected to the frame 41 or the shaft bracket 21, or it can be fixedly mounted on a rod holder 72. When the rod holder 72 is used to mount and fix the guide rod 71, the position of the rod holder 72 is as follows... Figures 11-13 As shown, the guide rod 71 is positioned on both sides of the cover in the width direction between the conveyor roller assembly 29 and the guide rod 43. The guide rod 71 is inclined, with its upward-inclined end located above the inner side of the folded portion 53 of the cover, and its downward-inclined end located above the outer side of the folded portion 53 of the cover. Figure 12 The location of the central frame 72 is the outer side of the folded portion 53 of the covering, and the other side of the folded portion 53 is the inner side of the folded portion 53. During the folding and rolling process, the active roller group 46 pulls the covering to move, such as... Figure 12 As shown, the two ends of the rope segment 63 slide obliquely upward along the guide rod 71, and under the guidance of the guide rod 71, they fold inward toward the inside of the folding part 53 of the covering. After the covering is folded once, the rope segment 63 is wrapped inside the folded covering and is not exposed, which helps to make the covering look neat and beautiful.

[0082] In this embodiment, the production equipment for agricultural coverings further includes a second folding device 19 and a second welding device. The second folding device 19 is used to fold the two sides of the covering in the width direction to form a second folded edge 511. The second welding device is used to weld the second folded edge 511 to the covering. This design helps to enhance the tensile strength of the edge of the covering, avoid the edge of the covering from opening or tearing during later use, and improve the service life of the covering. After the second folded edge 511 is welded and fixed, the covering is continued to be conveyed and pressed and welded with the waist rope 6. Therefore, the second folding device 19 and the second welding device can be installed and fixed on the shaft frame 21 to perform folding and pressing welding on the covering that is about to be pressed and welded with the waist rope 6.

[0083] In this embodiment, the second welding device is one of the following: ultrasonic welding device, high-frequency welding device (such as radio frequency welding device), hot air welding device (such as hot press welding device), laser welding device, and wear-resistant overlay welding device (such as metal-based fabric chute welding device). Preferably, the second welding device is an ultrasonic welding device. Ultrasonic welding is fast, efficient, does not require needles or thread, produces a smooth welded surface without burrs, and has a good feel.

[0084] In this embodiment, the agricultural mulch production equipment further includes a splicing unit 1, which is used to splice multiple pieces of mulch arranged along the width direction of the mulch to form a wide-body mulch 5, in order to meet the needs of special scenarios, such as... Figure 32 As shown, the width of the wide-body cover 5 is N times that of a conventional cover. Increasing the width of the cover can effectively meet the usage requirements of certain special scenarios. Similarly, the wide-body cover 5 also needs to be folded by the folding device 2 19 and the folded part 2 511 is welded and fixed by the welding device 2 before being pressed and welded to the waist rope 6.

[0085] Specifically, the splicing unit 1 has at least a welding device 100 and a plurality of conveying devices 10. Each conveying device 10 is used to convey one piece of covering material. Adjacent pieces of covering material are conveyed in parallel and partially overlapped under the conveying of the conveying device 10. The welding device 100 is located next to the overlapping part of the two adjacent pieces of covering material and is used to weld and fix the two adjacent pieces of covering material.

[0086] When the wide-body covering 5 is composed of two coverings, such as covering 51 and covering 52, as Figure 32 As shown, a welding device 3100 can be installed at the connection between cover 1 51 and cover 2 52 to weld and fix cover 1 51 and cover 2 52. Specifically, as shown... Figure 24 , Figure 26 , Figure 29 As shown, the splicing unit 1 at this time includes a welding device 100 and two conveying devices 10. One conveying device 10 has a frame 11 and a feeder 15 and a conveyor roller assembly 18 mounted on the frame 11, as shown. Figures 24-27 As shown, the material carrier 15 includes a shaft arm 151, a lifting device 152, and a braking device 153. One end of the shaft arm 151 is hinged to the frame 11, and the other end of the shaft arm 151 is suspended. The lifting device 152 is mounted on the frame 11, and its movable end is connected to the shaft arm 151. The lifting device 152 drives the suspended end of the shaft arm 151 to swing up and down to adjust the position of the shaft arm 151, facilitating the placement of material rollers of different thicknesses and adjusting the position of the material rollers to meet the requirements of its material spreading operation. Figure 24As shown, a reel 16 is rotatably mounted on one suspended end of the shaft arm 151. A material roller is securely fitted onto the reel 16. The rotation of the material roller drives the reel 16 to rotate synchronously, winding the covering material into a roll. The braking device 153 is fixedly mounted on the shaft arm 151 and is connected to the reel 16 via a transmission mechanism 17. Preferably, as shown... Figure 27 As shown, the transmission mechanism 17 is a gear set. The braking device 153 is used to control the rotation of the roller 16. Because the material roller is heavy and has a large rotational inertia, if the conveying speed of the cover needs to be reduced at a certain moment during the operation, the material roller cannot immediately and synchronously decrease its speed due to its large inertia. This causes the unfolded cover in the pressing unit 2 and splicing unit 1 to become loose and not tensioned, affecting the pressing and welding operation of the waist rope 6 and the cover. Therefore, the braking device 153 is set up to control the rotation speed of the material roller in real time as needed during the operation to ensure that the unfolded cover always remains taut.

[0087] Preferably, the braking device 153 is a magnetic powder brake.

[0088] Specifically, such as Figure 24 and Figure 25 As shown, the conveyor roller assembly 2 18 includes roller 1 181, roller 2 182, push-pull device 4 183, roller 3 184, roller 4 185, roller 5 186, roller 6 102, roller 7 103, and roller 8 113. Rollers 1 181, 2 182, 3 184, 4 185, 5 186, 6 102, 7 103, and 8 113 are rotatably mounted on frame 3 11. Of course, rollers 6 102 and 7 103 can also be mounted on frame 3 11. 3. Roller 8 113 is installed separately on frame 2 101, and then frame 2 101 is fixedly connected to frame 3 11. Since each conveying device 10 has roller 1 181, roller 2 182, roller 3 184, roller 4 185, roller 5 186, roller 6 102, roller 7 103, and roller 8 113 are shared by two or more conveying devices 10, in order to enable modular assembly of splicing unit 1, different rollers are installed on frame 1 41 and frame 2 101 respectively.

[0089] In this embodiment, the covering material unfolded by the material rollers passes sequentially through rollers 181, 182, 184, 185, 186, 113, 103, and 102 before leaving the splicing unit 1 and entering the pressing unit 2. Covering material 1 51 and covering material 2 52 are each conveyed to roller 8 113 via rollers 181, 182, 184, 185, and 186, respectively. Afterward, covering material 1 51 and covering material 2 52 begin to be conveyed synchronously and parallel, partially overlapping. Therefore, the welding device 3 100 should be located downstream of roller 8 113 in the covering material conveying direction, for example... Figure 24 , Figure 26 , Figure 29 and Figure 30 The welding device 3 100 shown is disposed between roller 8 113 and roller 7 103, thereby welding the overlapping portions of cover 1 51 and cover 2 52 together.

[0090] In this embodiment, as Figure 25 As shown, the push-pull device 183 is installed on the frame 11, and its movable end is connected to the roller 182. It is used to push the roller 182 to move and adjust the distance between the roller 182 and the roller 181, so as to better meet the conveying needs of the covering.

[0091] Preferred, such as Figure 24 , Figure 26 , Figure 29 and Figure 30 As shown, the welding device 3 100 is an ultrasonic welding device, which includes a push-pull device 5 104, a wheel seat 105, a pattern wheel 2 106, and an ultrasonic mold head 2 107. The pattern wheel 2 106 and the ultrasonic mold head 2 107 are respectively located on both sides of the overlapping part of the covering. The overlapping part of the covering passes through the pattern wheel 2 106 and the ultrasonic mold head 2 107. The ultrasonic mold head 2 107 is fixedly connected to the frame 2 101. The pattern wheel 2 106 is rotatably mounted on the wheel seat 105. The push-pull device 5 104 is fixedly mounted on the frame 2 101, and its movable end is connected to the wheel seat 105. It is used to push the pattern wheel 2 106 closer to or away from the ultrasonic mold head 2 107, thereby controlling the pressing and welding of the overlapping part of the covering.

[0092] In this embodiment, the second welding device can also be disposed between the eighth roller 113 and the seventh roller 103, so that when the third welding device 100 performs press welding on the overlapping part of the cover, the second welding device simultaneously performs press welding on the folded edge 511 of the wide-body cover 5, such as... Figure 24 , Figure 26 , Figure 28 , Figure 29 and Figure 31As shown, the welding device 2 is preferably an ultrasonic welding device, which includes an ultrasonic head 3 108, a push-pull device 3 109, a bearing 2 110, a pattern wheel 3 111, and a mounting frame 3 112. The ultrasonic head 3 108 and the pattern wheel 3 111 are respectively located on both sides of the folded edge part 2 511. The ultrasonic head 3 108 and the mounting frame 3 112 are fixedly connected to the frame 2 101. The bearing 2 110 is hinged to the mounting frame 3 112. The pattern wheel 3 111 is rotatably mounted on the bearing 2 110. The push-pull device 3 109 is connected to the mounting frame 3 112 or the frame 2 101. The movable end of the push-pull device 3 109 is connected to the bearing 2 110. By pushing and pulling the bearing 2 110 relative to the mounting frame 3 112, the distance between the pattern wheel 3 111 and the ultrasonic head 3 108 is adjusted, thereby controlling the pressing and welding of the folded edge part 2 511. Correspondingly, the folding device 2 19 is positioned upstream of the welding device 2 in the direction of the covering conveyor, for example... Figure 9 As shown, the two sides of the wide-body covering 5 are folded in the width direction by the folding tool 2 19.

[0093] In this embodiment, further, such as Figure 10 , Figure 24 and Figure 25 As shown, the frame 11 is equipped with a reciprocating translation mechanism 12, a welding trimming mechanism 13, and a clamping mechanism 14, as follows: Figure 10 As shown, the clamping mechanism 14 includes a fixed rod 141, a movable rod 142, a rack 143, and a pressing device 144. The pressing device 144 and the fixed rod 141 are fixedly connected to the frame 11. The movable rod 142 and the fixed rod 141 are spaced apart vertically. The movable rod 142 is connected to the pressing device 144. The pressing device 144 drives the movable rod 142 to move up and down to adjust the distance between the fixed rod 141 and the movable rod 142. The rack 143 is fixedly installed on the side of the movable rod 142 facing the fixed rod 141. When the movable rod 142 approaches the fixed rod 141, the rack 143 contacts the fixed rod 141. The two ends of the fixed rod 141 and the movable rod 142 are located on both sides of the width direction of the cover. This design allows the cover to pass through the space between the fixed rod 141 and the movable rod 142. When the movable rod 142 approaches the fixed rod 141, the rack 143 and the fixed rod 141 clamp and fix the cover.

[0094] In this embodiment, as Figure 25As shown, the reciprocating translation mechanism 12 includes a wheel axle 121, pulleys 122, transmission belts 123, and a drive device 124. The drive device 124 is fixedly installed on the frame 11 and is connected to the wheel axle 121 for transmission. There are two wheel axles 121, which are respectively rotatably installed on both sides of the width direction of the cover on the frame 11. Each wheel axle 121 has pulleys 122 installed at both the upper and lower ends. The pulleys 122 on the two wheel axles 121 are connected to each other through the transmission belts 123. The two transmission belts 123 are located at the upper and lower ends of the wheel axle 121.

[0095] In this embodiment, as Figure 25 As shown, the welding trimming mechanism 13 includes a mounting frame 131, an ultrasonic mold head 132, a flash cutter 133, a wheel axle 134, a flower wheel 135, a bearing 136, a mounting frame 137, a lifting device 138, and a driving device 139. The mounting frame 131 is fixedly connected to the transmission belt 123 at the upper end of the wheel axle 121, and the mounting frame 131 is slidably connected to the frame 11. The sliding direction is from one side of the width of the cover to the other side. This design realizes a reciprocating translation mechanism. 12 drives the mounting bracket 131 to slide back and forth on the frame 11. The ultrasonic head 132 and the flower wheel 135 are arranged vertically at intervals. The covering can pass between the ultrasonic head 132 and the flower wheel 135. The ultrasonic head 132 is fixedly connected to the mounting bracket 131. The flower wheel 135 is fixedly mounted on the axle 134. The axle 134 is rotatably mounted on the bearing seat 136. One end of the bearing seat 136 is hinged to the mounting bracket 137. The other end is hinged to the lifting device 138, which is mounted on the mounting frame 137. The lifting device 138 pushes the shaft seat 136 to swing up and down on the mounting frame 137, adjusting the height of the flower wheel 135, i.e., adjusting the distance between the flower wheel 135 and the ultrasonic head 132 above it, thereby controlling the pressing and welding of the covering. The mounting frame 137 is fixedly connected to the transmission belt 123 at the lower end of the axle 121, and simultaneously slides with the frame 11. The ultrasonic transducer 132 and the pattern wheel 135 are connected by a transmission belt 123, which drives the mounting frame 137 to slide on the frame 11. This allows the ultrasonic transducer 132 and the pattern wheel 135 to slide along one side of the width of the covering while maintaining a vertical spacing. With this design, when the two layers of covering are located between the ultrasonic transducer 132 and the pattern wheel 135, controlling the ultrasonic transducer 132 and the pattern wheel 135 to contact each other and slide on the frame 11 allows for pressing and welding of the two layers of covering, connecting them together. The drive device 139 is fixedly mounted on the mounting frame 137 and is connected to the axle 134 to drive the pattern wheel 135 to rotate.

[0096] In this embodiment, after the cover on one roll of material is fully unrolled, the next roll of material is placed on the carrier 15, and then the cover of the first roll of material is unrolled. Next, the unrolled end of the cover of the first roll of material is aligned with the end of the previously unrolled cover of the first roll of material to form two layers of cover. These two layers of cover are then led out from the first shaft roller 181 and the second shaft roller 182, and sequentially pass between the fourth ultrasonic mold head 132 and the fourth flower wheel 135, and between the fixed rod 141 and the movable rod 142. Then, the control... The pressing device 144 is activated, and the two layers of covering are clamped and fixed by means of the rack 143 and the fixing rod 141. Then, the conveying roller assembly 2 18 is adjusted to tension the two layers of covering. Then, the reciprocating translation mechanism 12 is controlled to drive the ultrasonic mold head 4 132 and the flower wheel 4 135 to move from one side to the other end in the width direction of the covering to perform ultrasonic pressing and welding of the two layers of covering together, thereby connecting the coverings of the front and rear rolls and ensuring that the splicing unit 1 can continuously supply coverings to the pressing unit 2.

[0097] In this embodiment, as Figure 25 As shown, the flash cutter 133 is fixedly mounted on the shaft seat 136. The flash cutter 133 is located on the side of the flower wheel 135 near the clamping mechanism 14. During the process of the reciprocating translation mechanism 12 driving the ultrasonic mold head 132 and the flower wheel 135 to move from one side to the other end in the width direction of the covering, the flash cutter 133 cuts off the excess material of the two layers of covering, improving the connection quality of the two layers of covering. Figure 25 As can be seen, the gap between the flower wheel 135 and the rack 143 is relatively large. Therefore, after the covers of the two front and rear rolls are connected, there is a lot of excess cover. Cutting off the excess cover with the flash cutter 133 helps to improve the connection quality of the two covers.
