Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural production tools, in particular to a device for producing a climbing net for vine crops and a production method. BACKGROUND

[0002] The traditional planting process of vine crops is to set up supports by manually pulling lines, specifically to form a net-shaped support by repeatedly inserting and winding the silk lines up and down. In the prior art, different lines are divided into a plurality of weft lines and weft lines in advance, and then the weft lines are repeatedly crossed and connected at specific positions of the warp lines to form a climbing net for vine crops, also known as a vine crop pulling net, which is generally formed by combining two warp lines and one weft line. However, there are some disadvantages:

[0003] ① The combination strength of warp and weft lines is poor, and the joint is prone to looseness during use;

[0004] ② According to the planting requirements of different vine crops, the height of the existing climbing net for vine crops, i.e. the distance between the two warp lines during preparation, is usually from several tens of centimeters to 1.8 meters or even 2.5 meters. When the height is small, the overall strength of the warp and weft lines after winding is sufficient to support the climbing of crops and the action of natural wind. However, as the height of the climbing net increases, only relying on the action of two warp lines and the weft line at the stress points of the two warp lines cannot support the overall weight of the vine crops and the action of wind, especially when the climbing net with a height of more than 1.5 meters is used, the overall collapse or collapse of the middle part of the climbing net often leads to crop lodging, resulting in crop loss;

[0005] ③ The existing climbing net manufacturing equipment can only prepare climbing nets composed of two warp lines and one weft line, such as the technical solutions disclosed in patent documents 2018107505039, 2021205552668, and 2022201440136. However, it cannot adapt to larger size and more complex structure climbing nets. SUMMARY

[0006] To solve the above problems, the present application provides a device for producing a climbing net for vine crops, and a production method for preparing a new climbing net using the device.

[0007] The new climbing net for vine crops has a structure different from existing climbing nets, which has a plurality of fixed points for warp and weft lines, and the winding drum structure is also redesigned considering product weight and arrangement and transportation factors.

Since the end of the weft is fixed with the warp, the weft on the weft wheel is unwound under the traction of the weft winding rack.

[0014] The transmission frame is connected with the post and is divided into two layers, the horizontal beam and the vertical beam of the upper layer form a plane with a height lower than the height of the lower edge of the circular hole of the post; in addition, two opposite posts are arranged on the plane near the post, and in the space between the plane formed by the two posts and the post, two outer warps and an inner warp guided by two "L" type warp unwinding racks and one "1" type warp unwinding rack are in contact with two warps pulled by two opposite weft winding racks and are initially formed. The specific process is that the three warps move uniformly and backward in the horizontal direction, and the warps pulled out from the weft wheel are in contact with and superimposed on the two outer warps and the inner warp in turn, forming a mesh in the same horizontal plane.

[0015] A mounting plate provided with a slidable mounting groove is fixed on the rear side of each of the two posts, at least one warp guide shaft is installed between the two mounting plates by means of bolt connection, and an outer guide wheel is sleeved on both ends of the warp guide shaft.

[0016] An auxiliary driving shaft is arranged on the same horizontal plane as the warp guide shaft, and any end of the auxiliary driving shaft is connected with a driving motor, so as to assist in moving the climbing net semi-finished product formed by the contact and superposition of the warp and the weft backward, thereby reducing the working pressure of the winding shaft.

[0017] Behind the plane formed by the crossbeam and the longitudinal beam, a rectangular support is arranged, the front end of the rectangular support is provided with a warp guide wheel on each side, a warp and weft fixing mechanism is arranged behind the right side of the warp guide wheel to fix the intersection of the warp and weft, and then the warp and weft are conveyed to the winding mechanism.

[0019] Preferably, the front end of the warp guide assembly mounted on the supporting plate is provided with an electromagnetic thread locker, which comprises a supporting shaft, a spring sleeved on the supporting shaft and a pair of iron thread pressing discs arranged below the spring, and the unwound warp passes between the two thread pressing discs; a manual knob is arranged on the supporting shaft, and the tightness between the two thread pressing discs can be adjusted by rotating the knob through the spring; the bottom of the lower thread pressing disc is provided with an electromagnet, and when the electromagnet is turned on, the upper thread pressing disc is attracted through the lower thread pressing disc, the friction with the warp is increased, and finally the warp is stopped; before stopping, the warp or the climbing net semi-finished product between the winding shaft and the unwinding mechanism is tensioned, so that the parts cannot stop synchronously under the action of inertia after stopping, and the stacking and winding of the warp and weft are caused.

[0020] Preferably, a cylinder is mounted on the inner wall of the round hole, the cylinder extends backward beyond the part of the vertical plate, two independent bearings are mounted on the part of the vertical plate, the outer ring of each bearing is sleeved with a belt pulley, a mounting bracket and a weft winding frame are respectively fixed on the rear end surface of each belt pulley, a weft wheel is arranged at the adjacent position of the fixed end of the weft winding frame, and the protruding ends of the two weft winding frames are located in the same vertical plane; the two belt pulleys are respectively connected with a motor arranged in the middle part of the vertical plate, and the motor drives the weft winding frames and the weft wheels to rotate in opposite directions with the center of the cylinder as the axis; since the end of the weft is fixed with the warp, the weft on the two weft wheels is unwound under the traction of the respective weft winding frames.

[0021] The warp and weft fixing mechanism comprises a right overlock machine and its independent thread supply mechanism, a left overlock machine and its independent thread supply mechanism; wherein the right overlock machine and its independent thread supply mechanism are arranged at the right side behind the warp thread guide wheel, and opposite front turning wheel groups and guide shafts are arranged at both sides of the last end of the rectangular support; opposite middle turning wheel groups and guide shafts are arranged right below the front turning wheel groups, i.e. at the bottom of the rectangular support; the left overlock machine and its independent thread supply mechanism are arranged at the left side of the lower layer of the transmission frame; opposite rear turning wheel groups and guide shafts are arranged at the outlet of the left overlock machine, so as to guide the climbing net after the left and right side overlock to the winding mechanism.

[0022] The warp and weft fixing mechanism is a glue applying mechanism arranged behind the warp thread guide wheel and a matched curing device, which fixes the warp and weft intersection parts at both sides and the middle part.

[0023] The warp and weft fixing mechanism is a heating pipe, and a heating channel and a cooling fan are arranged behind the warp thread guide wheel.

[0024] The second object of the present application is to provide a production method of the climbing net of the vine crops by using the special equipment, which comprises the following steps: ① installing three warp wheels on the base of the unwinding frame, and drawing two warps to the warp thread assembly on the supporting plate from both sides by the traction frame, or drawing three warps to the warp thread assembly on the supporting plate from both sides and the middle by the traction frame, and then passing through the warp thread assembly, and then passing through the round holes on the vertical plate to the other side along the two "L" type warp unwinding frames and the "1" type warp unwinding frame in the middle;

[0025] ② the warp thread contacts with the warp guide shaft, wherein the warps on both sides are clamped in the spiral threads on the outer thread wheels at both ends of the warp guide shaft, and the warps are continuously pushed from the inside to the outside in the normal rotation, so that the warps on both sides are tensioned and flattened to the outside; the warp in the middle is clamped in the spiral thread on the inner thread wheel in the middle of the warp guide shaft, and the warp is continuously pushed from both sides to the middle in the normal rotation, so that it is always in the middle position of the two outer warps;

[0026] ③ the warp continues to pass through the auxiliary driving shaft, the warp thread guide wheel and the warp and weft fixing mechanism, and reaches the winding shaft;

[0027] After the traction of the warp is completed, a single or double weft is drawn out from the weft wheel according to the need, passes through the weft winding frame, and is fixed with the outer warp at the same side of the second party, and then the winding shaft starts to wind, driving the warp to move, at the same time, the weft winding frame starts to rotate under the drive of the belt pulley, and the weft is wound around the plane formed by two or three warps in the space between the vertical plate and the warp guide shaft, and a net is formed; at the contact point of the weft and the two sides of the warp, the included angle of the two is adjusted by adjusting the winding speed of the winding shaft or the rotation speed of the weft winding frame;

[0028] After the warp and weft forming a net pass through the auxiliary drive shaft and the warp guide pulley, they enter the warp and weft fixing mechanism to fix the joint of the warp and weft, and then a climbing net is obtained, and then it is transported to the winding mechanism for winding.

[0029] A two-section or three-section cylinder core is sleeved on the winding shaft, the winding shaft is an expansion shaft, the winding servo motor drives the winding shaft to rotate, and at the same time, the winding frame drives the winding shaft to reciprocate along the axial direction under the action of the eccentric wheel or the transmission worm, so that the warps are evenly distributed on the cylinder core respectively, avoiding local protrusions, and finally a climbing net roll is wound.

[0030] Preferably, at the contact point of the weft and the warp, the included angle of the two is adjusted by adjusting the winding speed of the winding shaft or the rotation speed of the weft winding frame.

[0031] In the above step 5, according to the different types of climbing nets, there are several different steps:

[0032] Firstly, for the preparation of a climbing net with two warps, the warp and weft fixing mechanism only needs to fix the two warps distributed on the two sides and the weft in contact with them, and a lock edge machine is arranged behind the warp guide pulley, and the specific structure includes: first, a right lock edge machine and its independent thread supply mechanism are installed on the right side behind the warp guide pulley, and the right side of the climbing net semi-finished product is locked and edged, and the warp and weft are fixed; opposite front steering wheel groups and guide shafts are installed on both sides of the last end of the rectangular support, so that the horizontal backward transmission of the climbing net semi-finished product is converted into vertical downward transmission; opposite middle steering wheel groups and guide shafts are also arranged below the front steering wheel groups, i.e. at the bottom of the rectangular support, so that the vertical downward transmission of the climbing net semi-finished product is converted again into horizontal backward transmission; the lower layer of the transmission frame also includes a plane composed of a cross beam and a total amount, which is adjacent to the middle steering wheel group, and a left lock edge machine and its independent thread supply mechanism are installed on the left side of the plane, so as to lock and edge the left side of the horizontally transported climbing net semi-finished product after turning over, and fix the warp and weft; opposite rear steering wheel groups and guide shafts are arranged at the outlet of the left lock edge machine, so as to re-steer the climbing net with the left and right sides locked and edged, and guide it to the winding mechanism.

[0033] Secondly, for the preparation of climbing nets with three warp threads, since the junction of the warp and weft threads in the middle part cannot be fixed using an overlock machine, an adhesive applicator and a matching curing device are set behind the warp guide wheel to fix the junction of the warp and weft threads on both sides and in the middle part.

[0034] In addition, for the same preparation of a climbing net with three warp threads, since the warp and weft threads are coated with a low-melting-point polyester layer, they only need to be heated to 150℃-200℃ to fuse and bond their junctions. Therefore, the warp and weft thread fixing mechanism is a heating pipe. Only a heating channel and a cooling fan need to be set behind the warp thread guide wheel. The entire semi-finished climbing net enters the heating channel to be heated and fused together, and then is cooled by air blowing, which completes the fixing of the warp and weft threads.

[0035] Beneficial effects

[0036] Compared to existing equipment that can only produce climbing nets with two warp threads, this application can not only produce double-warp climbing nets currently on the market, but also efficiently and with high quality produce triple-warp climbing nets with higher strength and wider application range. Furthermore, based on the ideas and inspiration of the technical solution of this application, the production of climbing nets with more than three warp threads can also be achieved. By setting outer guide wheels and inner guide wheels that can control the position of the warp threads during the warp conductor transportation process, the regularity of the entire climbing net surface is maintained. In addition, the "L"-shaped warp unwinding frame and the ability to "change diameter" during the warp unwinding process greatly reduce the cost and difficulty of equipment manufacturing.

[0063] Embodiment 2

[0064] Reference Figure 4 、 5 , 6, 7, 9, the special equipment for producing the climbing net in the embodiment is basically the same as the structure in the embodiment, and the difference is that,

[0065] 1, the climbing net preparation of three warps is performed in the embodiment, the middle warp needs to be pulled to the warp guide assembly on the supporting plate, passes through the warp guide assembly, and reaches the other side along the middle “1”-shaped warp unwinding frame through the round hole on the vertical plate; the middle warp is clamped in the spiral thread on the inner guide wheel 19 in the middle of the warp guide shaft 17, and is continuously pushed from both sides to the middle during normal rotation, so that it is always in the middle position of the two outer warps.

[0066] 2. In this embodiment, the weft winding frame 13 in the middle of the device rotates in opposite directions to wind the warp yarn. Therefore, the two weft winding frames 13 need to rotate independently clockwise or counterclockwise, requiring two independently rotating pulleys 11 and their corresponding motors 5. The specific structure is as follows:

[0067] A cylinder is installed on the inner wall of the circular hole. The cylinder extends backward, and two independent bearings 10 are installed on the part of the cylinder that exceeds the vertical plate 2. Each bearing 10 has a pulley 11 fitted on its outer ring. A mounting frame and a weft winding frame 13 are fixed on the rear end face of each pulley 11. A weft wheel 14 is provided at the adjacent position of the fixed end of the weft winding frame 13. The protruding ends of the two weft winding frames 13 are located in the same vertical plane. The two pulleys 11 are respectively connected to a motor 5 located in the middle of the vertical plate 2, which drives the respective weft winding frames 13 and weft wheels 14 to rotate in opposite directions around the center of the cylinder. Since the end of the weft thread is fixed to the warp thread, the weft thread on the two weft wheels 14 is unwound under the traction of the respective weft winding frames 13.

[0068] 3. In this embodiment, the device has an electromagnetic locking device at the front end of the warp wire assembly 7 installed on the tray 6. The device includes a support shaft 30, a spring 31 sleeved on the support shaft 30, and a pair of iron pressure plates 32 located below the spring 31. The unwound warp passes between the two pressure plates 32. A manual knob 33 is provided on the support shaft 30. After rotation, the tightness of the connection between the two pressure plates 32 can be adjusted through the spring 31. An electromagnet 34 is installed at the bottom of the lower pressure plate 32. When turned on, the electromagnet attracts the upper pressure plate 32 through the lower pressure plate 32, increasing the friction with the warp and eventually stopping it. Before stopping, the warp or climbing net semi-finished product between the winding shaft 28 and the unwinding mechanism is tensioned to prevent the components from failing to stop synchronously due to inertia after the machine stops, causing the warp and weft to stack and entangle.

[0069] 4. In this embodiment, when preparing a climbing net with three warp threads, since the junction of the warp and weft threads in the middle part cannot be fixed using an overlock machine, an adhesive applicator and a matching curing device are set behind the warp guide wheel as a warp and weft thread fixing mechanism 34 to fix the junction of the warp and weft threads on both sides and in the middle part.

[0070] Example 3

[0071] refer to Figure 10The special equipment for producing the climbing net in the embodiment is basically identical with the structure described in the embodiment 1, and the difference is that the warp and weft in the embodiment adopt the warp and weft with low melting point polyester wrapping layer, and only need to be heated at 150-200 DEG C to fuse and bond at the intersection, so that the warp and weft fixing mechanism 34 is a heating pipe, and only needs to set a heating channel and a cooling fan behind the warp guide wheel, and the whole climbing net semi-finished product enters the heating channel to be heated, fused and bonded, and then is cooled by wind blowing to complete the fixing of the warp and weft.
