Description

Technical Field

[0001] This invention relates to the field of shade net rolling device technology, specifically a shade net rolling device with automatic cutting function. Background Technology

[0002] Shade nets are made from polyethylene, high-density polyethylene, PE, PB, PVC, recycled materials, virgin materials, and polyethylene propylene, among other raw materials. They undergo UV stabilizer and anti-oxidation treatment, resulting in high tensile strength, aging resistance, corrosion resistance, radiation resistance, and lightweight properties. They are widely used in the protective cultivation of vegetables, flowers, edible fungi, seedlings, medicinal herbs, and in aquaculture and poultry farming. The main functions of shade nets are to regulate light and temperature, prevent damage from heavy rain, high temperatures, and the spread of pests and diseases, significantly improving crop yield and quality.

[0003] After the shade net is woven and processed, it is usually rolled into a roll. In order to facilitate later sales and transportation, the large rolls of woven shade net need to be divided into smaller rolls of a certain specification. The shade net is rolled to the required length by the rotation of the winding roller on the shade net winding device. Then, the shade net is cut off by a cutter. However, during the cutting process, the shade net is tightened and straightened by the winding roller. As the cutter gradually cuts the shade net, the tension of the shade net gradually decreases, and the cut part of the shade net is prone to skewing, resulting in an uneven cut and affecting the quality of the cut. Summary of the Invention

[0004] The purpose of this invention is to provide a shade net rolling device with automatic cutting function to solve the problems mentioned in the background art.

[0008] Preferably, the side of the fixing plate is provided with two T-shaped grooves, and a T-shaped block is slidably installed on the inner wall of each T-shaped groove. One end of the connecting shaft is fixedly inserted through the T-shaped block and extends to the other side of the T-shaped block. A strip groove is provided through the inner wall of the T-shaped groove.

[0009] Preferably, the outer wall of the connecting shaft is slidably connected to the inner walls of the first and second strip grooves, and an adjusting column is fixedly installed at one end of the connecting shaft. An inclined groove is provided on the inner wall of the second strip groove, and the outer wall of the adjusting column is slidably connected to the inner wall of the inclined groove.

[0010] Preferably, a plurality of support columns are slidably installed through the circular block. A circular frame is fixedly installed at one end of each support column. An elastic element is slidably installed on the outer wall of the support column. Both ends of the elastic element are fixedly connected to the side of the circular frame and the side of the circular block. A support plate is fixedly installed on the outer wall of the circular block. One end of the support plate slidably passes through the fixed plate and extends to the other side of the fixed plate. The side of the support plate abuts against the side of the movable sleeve.

[0011] Preferably, a connecting column is fixedly installed on the side of the concave frame, a swing bar is fixedly installed on the outer wall of the connecting column, and an arc-shaped groove 1 and an arc-shaped groove 2 are provided through the fixing plate, and the outer wall of the connecting column is slidably connected to the inner wall of the arc-shaped groove 1.

[0012] Preferably, one end of the swing bar is rotatably connected to the side of the fixed plate via a fixed shaft, and a limit post is fixedly and continuously installed on the side of the swing bar. The outer wall of the limit post is slidably connected to the inner wall of the second arc groove. An arc rod is slidably installed through the outer wall of the limit post. The two ends of the arc rod are fixedly connected to the inner wall of the second arc groove. An elastic element two is slidably connected to the outer wall of the arc rod. The two ends of the elastic element two abut against the inner wall of the second arc groove and the outer wall of the limit post.

[0013] Preferably, a T-shaped groove is provided on the side of the fixing plate, and a T-shaped block is slidably installed on the inner wall of the T-shaped groove. The bottom surface of the T-shaped block is elastically connected to the inner wall of the T-shaped groove through an elastic element.

[0014] Preferably, a hinge frame is fixedly installed on the bottom surface of the second T-shaped block, a roller is hinged to the inner wall of the hinge frame, the outer wall of the roller abuts against the bottom surface of the swing bar, and an inclined surface is provided on the side of the second T-shaped block, and the bottom surface of the round block is slidably connected to the inclined surface of the second T-shaped block.

[0015] Compared with the prior art, the beneficial effects of the present invention are: When the second motor drives the screw to rotate, the screw drives the movable sleeve and the cutter to move and contact the shade net. During this process, the movable sleeve moves away from the support plate. At this time, the first elastic element pushes the round block to move towards the fixed plate. The two inclined grooves on the round block drive the two adjusting columns to move closer to each other, and drive the two connecting shafts and the two clamping rollers to move closer to each other. The two clamping rollers clamp and fix the shade net. At the same time, the round block pushes the inclined surface to drive the second T-shaped block, the hinge frame and the roller to move downward. The roller pushes the swing bar and the connecting column to swing downward. The connecting column drives the concave frame and the pressing roller to swing downward. The pressing roller presses and fixes the shade net on the winding roller. The second motor continues to drive the screw to rotate, driving the movable sleeve and the cutter to move. The cutter cuts the shade net between the pressing roller and the clamping roller, ensuring that the shade net is straight and not subjected to excessive stretching during cutting. The cut part of the shade net is not easy to be skewed, ensuring that the shade net is cut more neatly, thereby improving the cutting quality. When the cutter cuts the shade net, the pressing roller presses the shade net onto the winding roller. After the cutter cuts the shade net, the pressing roller keeps one end of the shade net pressed and fixed on the winding roller. The shade net wound on the winding roller will not come loose, making it easy for workers to tie the wound shade net tightly. At the same time, the other cut end of the shade net is held by two clamping rollers, making it difficult for the shade net to shrink and fall off the winding equipment. The shade net can be manually wound back onto the winding roller for the next roll, improving the winding efficiency. Attached Figure Description

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] like Figures 1-10As shown, this application provides a shade net rolling device with automatic cutting function, including: a support frame 1, a fixed frame 101 installed on the support frame 1, a rotating shaft 102 rotatably installed through the fixed frame 101 via a bearing, a winding roller 103 installed on the outer wall of the rotating shaft 102, a limit block provided on the rotating shaft 102 to limit the inner wall of the winding roller 103, so that when the rotating shaft 102 rotates, it drives the winding roller 103 to rotate, and a plurality of guide rollers 107, guide rollers 108 and conveying rollers 109 are rotatably installed on the side of the support frame 1. The guide rollers 107 and guide rollers 108 guide the shade net to prevent folding and bending, and the conveying rollers 109 support and convey the shade net.

[0021] The cutting mechanism 2 is located on one side of the support frame 1. The cutting mechanism 2 includes a fixed plate 201 fixedly installed on the inner wall of the support frame 1, a housing 202 fixedly installed on the side of the fixed plate 201, a movable sleeve 204 slidably installed on the inner wall of the housing 202, and a cutter 205 fixedly installed on the side of the movable sleeve 204. Specifically, such as Figures 1-2 As shown, a motor 104 is fixedly installed on the side of the support frame 1. Sprockets 105 are fixedly installed on the outer wall of the output rod of the motor 104 and the outer wall of the rotating shaft 102. The outer walls of the two sprockets 105 are connected by a chain 106.

[0022] In this embodiment: the motor 104 drives the sprocket 105 and chain 106 to rotate, which in turn drives the shaft 102 and winding roller 103 to rotate and wind up the shade net.

[0023] Specifically, such as Figure 9 As shown, a screw 203 is rotatably mounted on one side of the inner wall of the housing 202 via a bearing. The outer wall of the screw 203 is threadedly connected to the inner wall of the movable sleeve 204. A motor 206 is fixedly mounted on the side of the fixed plate 201. The output rod of the motor 206 rotatably passes through the fixed plate 201 and is fixedly connected to one end of the screw 203.

[0024] In this embodiment: the motor 206 drives the screw 203 to rotate, and the screw 203 drives the movable sleeve 204 and the cutter 205 to move, so that the cutter 205 moves more stably and cuts the shade net more stably.

[0025] The fixing mechanism 3 is located on one side of the support frame 1. The fixing mechanism 3 includes two clamping rollers 304 located on one side of the fixing plate 201. A connecting shaft 303 is fixedly installed on the inner wall of each clamping roller 304. A round block 307 is provided on the other side of the fixing plate 201. Two strip grooves 311 are provided through the round block 307. Specifically, such as Figures 3-10As shown, the side of the fixing plate 201 is provided with two T-shaped grooves 301, and a T-shaped block 302 is slidably installed on the inner wall of each T-shaped groove 301. One end of the connecting shaft 303 is fixedly inserted through the T-shaped block 302 and extends to the other side of the T-shaped block 302. A strip groove 305 is provided through the inner wall of the T-shaped groove 301.

[0026] In this embodiment: the T-shaped groove 301 limits the movement of the T-shaped block 302, making the movement of the T-shaped block 302 more stable, which in turn drives the connecting shaft 303 and the clamping roller 304 to move more stably, ensuring that the clamping roller 304 clamps the shade net more stably.

[0027] Specifically, such as Figures 3-10 As shown, the outer wall of the connecting shaft 303 is slidably connected to the inner wall of the first strip groove 305 and the inner wall of the second strip groove 311. An adjusting column 313 is fixedly installed through one end of the connecting shaft 303. An inclined groove 312 is provided on the inner wall of the second strip groove 311. The outer wall of the adjusting column 313 is slidably connected to the inner wall of the inclined groove 312.

[0028] In this embodiment: when the circular block 307 moves, the inclined groove 312 on the circular block 307 drives the adjusting column 313 to move, and the adjusting column 313 drives the connecting shaft 303 and the clamping roller 304 to move, so that the clamping roller 304 fixes the shade net. When the cutter 205 cuts the shade net, the shade net is not easy to move, ensuring the quality of the cut.

[0029] Specifically, such as Figures 3-10 As shown, a plurality of support columns 306 are slidably installed through the circular block 307. A circular frame 308 is fixedly installed at one end of the support column 306. An elastic element 309 is slidably installed on the outer wall of the support column 306. The two ends of the elastic element 309 are fixedly connected to the side of the circular frame 308 and the side of the circular block 307. A support plate 310 is fixedly installed on the outer wall of the circular block 307. One end of the support plate 310 slidably passes through the fixed plate 201 and extends to the other side of the fixed plate 201. The side of the support plate 310 abuts against the side of the movable sleeve 204.

[0030] In this embodiment: the circular block 307 is limited by the support column 306, so that the circular block 307 moves more stably; the elastic element 309 applies elastic force to the circular block 307, so that the circular block 307 has a continuous thrust.

[0031] The pressing mechanism 4 is located on one side of the support frame 1. The pressing mechanism 4 includes a concave frame 401 located on one side of the fixed plate 201. A fixed column 402 is fixedly installed on the inner wall of the concave frame 401, and a pressing roller 403 is fixedly installed on the outer wall of the fixed column 402.

[0032] Specifically, such as Figures 5-7As shown, a connecting column 404 is fixedly installed on the side of the concave frame 401, and a swing bar 406 is fixedly installed on the outer wall of the connecting column 404. The fixing plate 201 is provided with an arc groove 405 and an arc groove 409. The outer wall of the connecting column 404 is slidably connected to the inner wall of the arc groove 405.

[0033] In this embodiment: the swing bar 406 can drive the concave frame 401 and the pressing roller 403 to swing and press the shade net. The pressing roller 403 cooperates with the winding roller 103 to press and fix the shade net on the other side of the cutter 205, so that the cutter 205 cuts the shade net more evenly.

[0034] Specifically, such as Figures 5-7 As shown, one end of the swing bar 406 is rotatably connected to the side of the fixed plate 201 via a fixed shaft 407. A limit post 408 is fixedly installed through the side of the swing bar 406. The outer wall of the limit post 408 is slidably connected to the inner wall of the arc groove 409. An arc rod 410 is slidably installed through the outer wall of the limit post 408. Both ends of the arc rod 410 are fixedly connected to the inner wall of the arc groove 409. An elastic element 411 is slidably connected to the outer wall of the arc rod 410. Both ends of the elastic element 411 abut against the inner wall of the arc groove 409 and the outer wall of the limit post 408.

[0035] In this embodiment: the arc-shaped rod 410 makes the swing of the limiting post 408 and the swing bar 406 more stable, and the elastic element 411 applies elastic force to the limiting post 408.

[0036] Specifically, such as Figures 5-7 As shown, a T-shaped groove 412 is provided on the side of the fixed plate 201, and a T-shaped block 413 is slidably installed on the inner wall of the T-shaped groove 412. The bottom surface of the T-shaped block 413 is elastically connected to the inner wall of the T-shaped groove 412 through an elastic element 414.

[0037] In this embodiment: the T-shaped groove 412 is used to limit the movement of the T-shaped block 413, making the movement of the T-shaped block 413 more stable; the elastic element 414 is used to apply elastic force to the T-shaped block 413.

[0038] Specifically, such as Figures 5-7 As shown, a hinge frame 415 is fixedly installed on the bottom surface of T-shaped block 413. A roller 416 is hinged to the inner wall of the hinge frame 415. The outer wall of the roller 416 abuts against the bottom surface of the swing bar 406. An inclined surface 417 is provided on the side of T-shaped block 413. The bottom surface of the round block 307 is slidably connected to the inclined surface 417 of T-shaped block 413.

[0039] In this embodiment: when the circular block 307 moves, the circular block 307 presses against the inclined surface 417, causing the T-shaped block 413 to move downward. The T-shaped block 413 drives the hinge frame 415 and the roller 416 to move downward. The roller 416 presses against the swing bar 406, causing the swing bar 406 to swing downward, which in turn drives the connecting column 404, the concave frame 401, and the pressing roller 403 to swing downward, pressing and fixing the sunshade net.

[0040] Specifically, the shade net is guided by conveyor roller 109, guide roller 2 108, and guide roller 1 107 and then connected to winding roller 103. Motor 1 104 is turned on to rotate shaft 102 and winding roller 103 to wind the shade net. After the shade net is wound up, motor 2 206 is turned on to rotate screw 203. During the contact process between screw 203 and moving sleeve 204 and cutter 205 with the shade net, the moving sleeve 204 moves away from support plate 310 and no longer contacts it. At this time, elastic element 1 309 pushes round block 307 towards fixed plate 201. The two inclined grooves 312 on 307 drive the two adjusting columns 313 to move closer together, which in turn drives the two connecting shafts 303 and the two clamping rollers 304 to move closer together. The two clamping rollers 304 clamp and fix the sunshade net. At the same time, the circular block 307 pushes the inclined surface 417 to move the T-shaped block 413, the hinge frame 415 and the roller 416 downward. The roller 416 pushes the swing bar 406 and the connecting column 404 to swing downward. The connecting column 404 drives the concave frame 401 and the pressing roller 403 to swing downward. The pressing roller 403 presses and fixes the sunshade net on the winding roller 103. The motor 206 continues to drive... The screw 203 rotates, driving the moving sleeve 204 and the cutter 205 to move. The cutter 205 cuts the shade net between the pressing roller 403 and the clamping roller 304, ensuring that the shade net is straightened and not subjected to excessive stretching during cutting, and that the cut part of the shade net is not prone to skewing, ensuring a neater cut. After cutting, the pressing roller 403 keeps one end of the shade net pressed and fixed on the winding roller 103, preventing the shade net wound on the winding roller 103 from coming loose. The worker then tightens the wound shade net, while the other cut end of the shade net is held by the two clamping rollers 304. With the 04 clamping mechanism in place, the shade net is less likely to shrink and fall off the winding device. Pulling one side of the shade net turns on motor 206 in reverse, causing screw 203 to rotate. This causes movable sleeve 204 and cutter 205 to move and return to their original positions. At this time, movable sleeve 204 presses and pushes support plate 310 to move and return to its original position. Support plate 310 then drives round block 307 to return to its original position. The two clamping rollers 304 and pressing roller 403 open and return to their original positions. Remove winding roller 103 and the wound shade net, install another winding roller 103 on the rotating shaft 102, connect one end of the shade net to winding roller 103, and continue the winding process.

[0041] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity.

[0042] This invention is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.
