Abstract
Description
Technical Field
[0001] This invention relates to the field of agricultural product technology, and in particular to the manufacture of a cold-proof cloth for plant growth protection. Background Technology
[0002] The main purpose of frost protection cloth is to protect plants from freezing to death or frost damage in winter, as well as from being burned when the temperature rises suddenly. When used to protect fruit trees, it can also protect the fruit, and provide protection against birds, insects, diseases, sun, and cold.
[0003] Existing winter protection cloths are in the form of plastic film, and are mostly used by wrapping plants with a cloth. This wrapping method is inconvenient, difficult to secure, time-consuming, and laborious, and is also easily blown away by the wind. Subsequently, some users added ropes to hold the lower edges of the cloth, but this method of tying the lower edges of the cloth with ties is unstable and prone to coming loose. To address this, some users directly tore or cut holes in the cloth to thread ropes through, but this method has low tensile strength, and the holes are easily torn, affecting its use. Summary of the Invention
[0004] The purpose of this invention is to provide a method and equipment for manufacturing perforated frost protection cloth. The resulting frost protection cloth has fixing holes suitable for installation and fixation, which effectively solves the above-mentioned technical problems, facilitates production and operation, improves the usability of frost protection cloth, and is beneficial to plant growth protection.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] Method for making perforated cold-proof fabric, the method includes the following steps:
[0007] Step 1: Provide non-woven fabric and reinforcing sheets on the production line, preferably with PE material for the reinforcing sheets;
[0008] Step 2: On the production line, the welded section formed by ultrasonic heat sealing will laminate and bond the reinforcing sheet to the corresponding side of the non-woven fabric, forming a multi-layered open area.
[0009] Step 3: Using machines arranged on the production line, holes are drilled in the opening area to obtain fixed holes at certain intervals. The fixed holes penetrate the upper and lower sides of the opening area in the stacking direction.
[0010] Step 4: Store the non-woven fabric with the holes made to obtain spare perforated cold-proof fabric.
[0011] The above-mentioned solution is further described as follows: the method is carried out under a roll-to-roll process. In step one, a first fabric body, a second fabric body, a first reinforcing sheet, and a second reinforcing sheet are provided respectively by unwinding. Subsequently, the first reinforcing sheet is bonded to the corresponding side of the first fabric body to form a first opening area, and the second reinforcing sheet is bonded to the corresponding side of the second fabric body to form a second opening area. The first and second opening areas of the first and second fabric bodies are then perforated to obtain fixed holes at a certain interval. The side of the first fabric body opposite to the first opening area is connected to the side of the second fabric body opposite to the second opening area by splicing, so that the first and second fabric bodies are spliced into an ultra-wide perforated cold-proof fabric and then rolled up and packaged.
[0012] The above solution is further described in that the fixing hole is obtained by riveting the eyelet buckle to the corresponding opening area using a riveting machine, and the eyelet buckle has an outward-turned brim that clamps the opening area.
[0013] The above solution is further described in that the corresponding side of the first fabric body is covered with the first reinforcing sheet by inward folding and then bonded and fixed by the welded part formed by ultrasonic heat sealing; the corresponding side of the second fabric body is also covered with the second reinforcing sheet by inward folding and then bonded and fixed by the welded part formed by ultrasonic heat sealing.
[0014] Furthermore, in the above scheme, the splicing of the first fabric body and the second fabric body is completed by adhesive bonding and ultrasonic heat sealing.
[0015] The above scheme is further described in that the width of the first fabric body is greater than the width of the second fabric body, and the first fabric body is folded in the width direction after being perforated before being spliced with the second fabric body; the width is defined as the distance between the left and right sides in the unwinding direction.
[0016] To achieve the above objectives, the present invention provides a perforated cold-proof cloth manufacturing device based on the above method, which has the following features:
[0017] The first production line is equipped with a first unwinding assembly, a first ultrasonic heat sealing assembly, a first riveting machine, and a folding guide. The first riveting machine is installed on a moving track and performs reciprocating motion to follow the unwinding movement and insert eyelets into the opening area to construct fixing holes.
[0018] The second production line is equipped with a second unwinding assembly, a second ultrasonic heat sealing assembly, and a second riveting machine. The second riveting machine is installed on a moving track and performs reciprocating motion to follow the unwinding movement and insert eyelets into the opening area to construct fixing holes.
[0019] The ends of the first production line and the second production line partially overlap, and a dispensing assembly, a third ultrasonic heat sealing assembly, and a winding assembly are set in the overlapping area. The dispensing assembly and the third ultrasonic heat sealing assembly work together to complete the splicing of the first fabric and the second fabric.
[0020] The above-mentioned solution is further described as follows: the first riveting machine is mounted on the first base via a linear guide rail and is driven by a first servo mechanism to reciprocate linearly. The moving speed of the first riveting machine matches the unwinding speed of the first unwinding assembly, so that the action of the first riveting machine in inserting the eyelet button does not cause a relative stop and pull back during unwinding. The second riveting machine is mounted on the second base via a linear guide rail and is driven by a second servo mechanism to reciprocate linearly. The moving speed of the second riveting machine matches the unwinding speed of the second unwinding assembly, so that the action of the second riveting machine in inserting the eyelet button does not cause a relative stop and pull back during unwinding.
[0021] The method for producing frost protection cloth provided by this invention uses non-woven fabric, which has good breathability, sun protection, cold protection, and insect and bird protection. The non-woven fabric has perforated areas, which are multi-layered structures composed of non-woven fabric and reinforcing sheets. These perforated areas not only enhance the edge structure of the frost protection cloth through edge finishing, improving its tensile and tear resistance, but also allow for the creation of fixed holes at regular intervals using mechanical equipment. These holes facilitate the secure fixing of the frost protection cloth, ensuring stable adhesion to plants and preventing it from being blown away by the wind, thus enhancing its protective effect. Furthermore, the reinforcing sheets strengthen the fixed holes, greatly improving their structural integrity and tensile strength. The structure is simple, easy to manufacture, and durable.
[0022] The cold-proof cloth production equipment provided by this invention can realize the continuous production of perforated cold-proof cloth, improve production efficiency and quality, and has a simple structure and low investment cost. Attached Figure Description

[0029] The following will further explain the concept, specific structure, and technical effects of the present invention in conjunction with the accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention.
[0030] It should be noted that in the description of this invention, the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0031] See Figures 1-5 As shown, the present invention provides a method for manufacturing perforated cold-proof fabric, which includes the following steps:
[0032] Step 1: Provide non-woven fabric and reinforcing sheets on the production line;
[0033] Step 2: On the production line, the welded section formed by ultrasonic heat sealing will laminate and bond the reinforcing sheet to the corresponding side of the non-woven fabric, forming a multi-layered open area.
[0034] Step 3: By drilling holes in the opening area using machines arranged on the production line, fixed holes with a certain interval are obtained, and the fixed holes penetrate the upper and lower sides of the opening area in the stacking direction.
[0035] Step 4: Store the non-woven fabric with the holes made to obtain spare perforated cold-proof fabric.
[0036] Figure 6 As shown, this method enables continuous production of frost protection cloth and pre-fabrication of fixing holes for easy fixing of the cloth during subsequent use, avoiding manual hole drilling. The resulting fixing holes have better structural integrity and tensile strength, are convenient and durable, and achieve stable bonding between the frost protection cloth and plants, making it less susceptible to being blown away by the wind, thus enhancing the protective effect.
[0037] The preferred method described above is a roll-to-roll process, which facilitates continuous production and is suitable for manufacturing cold-proof fabrics of different sizes. In step one, the first fabric body 10, the second fabric body 20, the first reinforcing sheet 30, and the second reinforcing sheet 40 are provided by unwinding. Subsequently, the first reinforcing sheet is bonded to the corresponding side of the first fabric body to form a first opening area 11, and the second reinforcing sheet is bonded to the corresponding side of the second fabric body to form a second opening area 21. The first and second opening areas of the first and second fabric bodies are then perforated to obtain fixing holes 50 at certain intervals. The side of the first fabric body opposite to the first opening area is connected to the side of the second fabric body opposite to the second opening area by splicing, so that the first and second fabric bodies are spliced into an ultra-wide perforated cold-proof fabric and rolled up for packaging to meet the needs of different occasions.
[0038] In this embodiment, during manufacturing, the corresponding sides of the first fabric are folded over and the first reinforcing sheet 30 is covered. Similarly, the corresponding sides of the second fabric are folded over and the second reinforcing sheet 40 is covered. This results in multi-layered perforated areas with better structural integrity, improving not only the edge structure of the cold-proof fabric but also facilitating perforation fabrication. In this embodiment, the first and second reinforcing sheets are preferably made of PE material, which has good thermoplasticity and is easy to bond with non-woven fabric. First and second reinforcing sheets of a certain width are selected as needed to meet the perforation requirements. Figure 4 As shown, the first welded portion 61 and the second welded portion 62 are formed by ultrasonic heat sealing. In this embodiment, the first welded portion 61 is dot-shaped and arranged in an array, mainly used to weld the non-woven fabric and the reinforcing sheet, stabilizing the multi-layer structure. The second welded portion 62 is used to fix the folded ends of the first and second fabrics. The second welded portion 62 is S-shaped and arranged in a straight line, with the S-shapes of adjacent second welded portions partially intersecting in the distribution direction to increase the welding area and continuity, making it less prone to separation. Through the cooperative fixation of the first and second welded portions, the overall structural integrity of the opening area is improved, preventing interlayer peeling. The reinforcing sheet is stably embedded inside the internal opening area, ensuring that the fixing holes are not easily deformed, and facilitating the use of accessories such as pull ropes to hold the cold-proof fabric. In this embodiment, the corresponding sides of the first and second reinforcing pieces also follow the folding of the first and second fabrics to form corresponding arc-shaped recovery portions 31 and 41. Utilizing the structure of the arc-shaped recovery portions 31 and 41, not only is the position of the reinforcing pieces stabilized, but the stress at the bending parts of the fabric edges is also reduced, which protects the bending parts and effectively improves the stress buffer on the tension side of the fixing hole 50, thus extending the service life of the fixing hole.
[0039] In this embodiment, the fixing hole 50 is obtained by riveting the eyelet buckle 70 to the opening area by a riveting machine. The eyelet buckle 70 pierces the first opening area 11 or the second opening area 21 and is fixed. The through hole in the middle of the eyelet buckle 70 forms the fixing hole 50, resulting in a smooth and tough inner hole wall, which is conducive to operations such as tying ropes and hanging hooks. Figure 5As shown, the eyelet buckle 70 has an outward-turned brim clamping opening area, forming an upper and lower clamping effect. This not only increases the connection area and obtains a stable connection structure, but also clamps the multi-layer structure of the opening area, making the area around the fixing hole form a tight whole, which greatly improves the tensile and tear resistance.
[0040] Figure 3 As shown, the cold-proof cloth produced in this embodiment can be made from a single sheet of non-woven fabric, or it can be constructed by splicing the first fabric body 10 and the second fabric body 20 to obtain an ultra-wide cold-proof cloth. The cold-proof cloth has fixing holes 50 on both the left and right sides. The splicing of the first fabric body 10 and the second fabric body 20 is preferably completed by adhesive bonding and ultrasonic heat sealing to increase connectivity and obtain a spliced part A with better tensile and tear resistance, thus improving the usability of the cold-proof cloth. In this embodiment, it is preferred that the width of the first fabric body is greater than the width of the second fabric body, and the first fabric body is folded in the width direction after the hole is opened before being spliced with the second fabric body, which facilitates subsequent winding and packaging operations. The width mentioned in this embodiment is defined as the distance between the left and right sides in the unwinding direction. This method allows for the production of cold-proof cloths of different widths, with pre-made fixing holes for convenient subsequent use. In use, the length of the cold-proof cloth can be obtained by free cutting, that is, manually cutting the cloth after unwinding to the appropriate length to meet different occasions. Figure 6 As shown, when in use, the frost protection cloth can be directly covered to the plants or used with a corresponding support to cover the plants. A pull rope 200 can be tied to the fixing hole 50 to hold the frost protection cloth in place, so that the frost protection cloth and the plants are stable and not easily blown away by the wind, thereby improving the protective effect and making the frost protection cloth easier to install.
[0041] See Figures 1-5 As shown, the present invention also provides a perforated cold-proof cloth manufacturing equipment, which is compatible with the above-described method for production. It has a first production line 800 and a second production line 900, which are arranged crosswise, with their ends partially overlapping. An adhesive dispensing assembly 101, a third ultrasonic heat-sealing assembly 102, and a winding assembly 103 are installed in the overlapping area. The adhesive dispensing assembly and the third ultrasonic heat-sealing assembly cooperate to complete the splicing of the first and second cloth bodies, achieving adhesive dispensing followed by ultrasonic heat sealing, resulting in a better splicing structure. This structure is selected for use when splicing is required. The winding assembly 103 is existing technology, used for metering, winding, cutting, and packaging the processed cold-proof cloth.
[0042] The first production line 800 is used to process the first fabric 10. This first production line includes a first unwinding assembly 801, a first ultrasonic heat-sealing assembly 802, a first riveting machine 803, and a folding guide 804. The first unwinding assembly 801 unwinds the first fabric 10 and the first reinforcing sheet 30. In this embodiment, a first bending device 808 is also provided. The first bending device 808 is preferably a U-shaped clamping groove, which allows the first fabric 10 and the first reinforcing sheet 30 to pass through and automatically folds the corresponding side edges of the first fabric 10, while simultaneously covering the first reinforcing sheet 30. The first ultrasonic heat-sealing assembly 802 is located downstream of the first bending device 808 and is used to bond the first reinforcing sheet and the first fabric 10 together through a welded portion formed by ultrasonic heat sealing, forming a multi-layered first opening area. The first riveting machine 803, purchased commercially, is used to rivet eyelets onto the opening area to create a fixing hole 50. The first riveting machine 803 is mounted on a moving track and reciprocates, following the unwinding movement and inserting eyelets into the opening area to create the fixing hole. In this embodiment, the first riveting machine 803 is mounted on a first base 805 via a linear guide rail and driven by a first servo mechanism. The moving speed of the first riveting machine 803 matches the unwinding speed of the first unwinding assembly 801, ensuring that the action of inserting the eyelet does not cause a relative stop pull during unwinding, thus ensuring that continuous unwinding production is not affected while riveting the eyelets. After riveting, the first riveting machine 803 returns to its original position for the next opening process, and this cycle repeats. The relative relationship between the unwinding and the movement of the first riveting machine 803 can be used to calculate the opening position, thereby driving the first riveting machine 803 to insert eyelets and obtain different fixing hole relationships with ideal intervals. In this embodiment, the first servo mechanism includes a first servo motor 806 and a first traction belt 807. The first traction belt 807 is connected to the first riveting machine 803, thereby driving the first riveting machine 803 to reciprocate linearly along the linear guide rail. The movement is smooth and accurate, ensuring the quality and efficiency of the opening. In this embodiment, in order to meet the requirements of winding up the first fabric body with a larger width after production, the first production line 800 of this embodiment also introduces a folding guide 804. As shown in the figure, the folding guide 804 is a triangular structure that realizes the first fabric body to be folded in the width direction, forming a double-layer shape for backward conveying, so as to facilitate the subsequent winding operation. It can also be easily aligned and spliced with the second fabric body. When splicing, only the side without the opening is spliced. The second production line 900 is used to process the second fabric 20. The second production line is equipped with a second unwinding assembly 901, a second ultrasonic heat sealing assembly 902, and a second riveting machine 903. The second unwinding assembly 901 realizes the unwinding of the second fabric 20 and the second reinforcing sheet 40. In this embodiment, a second bending device 904 is also provided. The second bending device 904 is preferably a U-shaped clamping groove body, which realizes the passage of the second fabric 20 and the second reinforcing sheet 40 and automatically folds the corresponding side edges of the second fabric 20, while covering the second reinforcing sheet 40.The second ultrasonic heat-sealing assembly 902 is located downstream of the second bending device 904. It is used to bond the second reinforcing sheet and the second fabric 20 together through a welded section formed by ultrasonic heat sealing, creating a multi-layered second opening area. The second riveting machine 903, purchased commercially, is used to rivet eyelets onto the opening area to construct fixing holes 50. The second riveting machine 903 is mounted on a moving track and reciprocates, following the unwinding movement and inserting eyelets into the opening area to construct fixing holes. In this embodiment, the second riveting machine 903 is mounted on the second base 905 via a linear guide rail and driven by a second servo mechanism. The moving speed of the second riveting machine 903 matches the unwinding speed of the second unwinding assembly 901, ensuring that the eyelet insertion action does not cause a relative stop pull during unwinding, thus ensuring that continuous unwinding production is not affected while the eyelet is being riveted. After the eyelet is riveted, the second riveting machine 903 returns to its original position for the next hole-making process. This cycle repeats, and the hole-making position can be calculated by utilizing the relative movement of the unwinding and second riveting machine 903. This allows the second riveting machine 903 to drive the eyelet into place, achieving different fixed hole relationships with ideal spacing. In this embodiment, the second servo mechanism includes a second servo motor 906 and a second traction belt 907. The second traction belt 907 is connected to the second riveting machine 903, thereby driving the second riveting machine 903 to reciprocate linearly along a linear guide rail. The movement is smooth and accurate, ensuring the quality and efficiency of the hole-making process.
[0043] Of course, this equipment is also used in conjunction with other conventional components required for roll-to-roll production, such as conveyor rollers. Since roll-to-roll production is a mature technology, these conventional components will not be described in detail here. The ultrasonic heat-sealing assembly is existing technology, and its structure and principle will not be elaborated upon here.
[0044] The present invention provides a method for producing frost protection cloth using non-woven fabric, which has good breathability, sun protection, cold protection, and insect and bird protection. The non-woven fabric has perforated areas, which are multi-layered structures composed of non-woven fabric and reinforcing sheets. This improves the edge structure of the frost protection cloth and allows for the creation of fixed holes at regular intervals using mechanical equipment. These holes facilitate the secure fixing of the frost protection cloth, ensuring a stable bond with plants and preventing it from being blown away by the wind, thus enhancing its protective effect. The reinforcing sheets further strengthen the fixing holes, significantly improving their structural integrity and tensile strength. The structure is simple, easy to manufacture, and durable. The frost protection cloth production equipment enables continuous production of perforated frost protection cloth, improving production efficiency and quality. It also features a simple structure and low investment cost.
[0045] While preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention should not be limited to structures and operations that are exactly the same as those described above and shown in the drawings. Those skilled in the art can make many equivalent improvements and variations to the above embodiments through logical analysis, reasoning, or limited experiments without departing from the concept and scope of the present invention, but all such improvements and variations should fall within the scope of protection claimed by the present invention.
