[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] This embodiment aims to address the problem in existing methods and equipment for manufacturing durable canvas bags where it is difficult to reinforce the base during processing. This can lead to the base detaching during use if heavy items are placed inside. Please refer to [link / reference needed]. Figure 1-8 A method for manufacturing a durable canvas bag includes the following steps:

[0040] S1. Cut the abrasion-resistant fabric: Cut the abrasion-resistant fabric to the required size;

[0041] S2, Hot stamping on abrasion-resistant fabric: Hot stamping is applied to the surface of the abrasion-resistant fabric to print the desired image onto the fabric 5.

[0042] S3. Sewing and shaping: The wear-resistant fabric is made into a canvas bag style with the help of manual labor and machinery;

[0043] S4. Handle sewing: The handle is initially sewn to the canvas bag using manual or mechanical assistance.

[0044] S5, Reinforced base: Add a layer of reinforcing fabric 5 to the fabric 5 of the canvas bag base, and add a reinforcing line between the base fabric 5 and the reinforcing fabric 5;

[0045] S6. Shaping: Sew the base to the canvas bag for the final stitching;

[0046] When reinforcing the fabric 5 of the canvas bag base, the two layers of fabric 5 are pressed and bonded together. Before bonding, the fabric 5 is processed by the equipment to form a semi-circular arch. After forming the semi-circular arch, the two layers of fabric 5 are bonded and shaped. Then, reinforcing ropes are inserted into the arch. The inserted reinforcing ropes can improve the overall strength of the canvas bag base.

[0047] The system includes a processing table 1, with grooves 11 at both ends. A slider 12 is slidably connected within each groove 11, and an adsorption assembly 2 for adsorbing fabric 5 is fixedly connected to each slider 12. A hydraulic rod 13 for pushing the adsorption assembly 2 is installed on the inner side of the groove 11, located on one side of the adsorption assembly 2. One side of the hydraulic rod 13 is fixedly connected to the inner side of the processing table 1. An extrusion assembly 3 for squeezing the fabric 5 is fixedly installed above the processing table 1. A forming assembly 4 is located in the middle of the processing table 1, positioned between the two adsorption assemblies 2. The design of the grooves 11 and sliders 12 allows the adsorption assembly 2 to slide smoothly on the processing table 1, ensuring precise movement of the adsorption assembly 2. The adsorption component 2 is used to adsorb the fabric 5 for subsequent processing and treatment. By adsorbing the fabric 5, the position and shape of the fabric 5 can be accurately controlled. The extrusion component 3 is located above the processing table 1 and is used to extrude the fabric 5. By extruding the fabric 5, it can be made more compact, improving the strength and wear resistance of the canvas bag. The forming component 4 is located in the middle part of the processing table 1 and is used to suction the fabric 5 into an arch shape. Through the forming component 4, reinforcing ropes can be inserted between the two layers of fabric 5, which helps to improve the strength of the canvas bag base. The function and beneficial effect of the processing table 1 structure is to improve processing efficiency, ensure processing quality, and realize the control and adjustment of the shape of the fabric 5.

[0048] The adsorption assembly 2 includes an adsorption chamber 21 fixedly connected to the slider 12. The adsorption chamber 21 is the main body of the adsorption assembly 2 and is used to maintain the position of the fabric 5. Through its fixed connection with the slider 12, it enables the movement and position adjustment of the processing table 1. One side of the adsorption chamber 21 is fixedly connected to the hydraulic rod 13. A sliding chamber 22 for preventing air leakage is slidably connected inside the adsorption chamber 21. The sliding chamber 22 is used to prevent air leakage, which can ensure that there is no gas leakage during the adsorption process and provide a stable air pressure for the adsorption effect. Telescopic rods 23 are slidably connected around the adsorption chamber 21. Springs 24 are sleeved on the telescopic rods 23. An adsorption plate 25 for adsorbing the fabric 5 is fixedly connected above the telescopic rods 23.

[0049] The adsorption plate 25 has adsorption holes 26. A support rod 27 is fixedly installed below the adsorption holes 26 in the adsorption chamber 21. The support rod 27 is used to support the fabric 5 located at the adsorption hole 26, which is a blind spot in the compression, when the extrusion assembly 3 presses downwards. This allows the fabric 5 in the blind spot to be compressed, improving the uniformity of the compression. A suction hole 28 is provided below the adsorption chamber 21, and a pipe 29 is fixedly connected to the suction hole 28. A negative pressure system is connected to the pipe 29 to create a negative pressure environment, allowing the fabric 5 to be compressed more evenly. The adsorption plate 25 is tightly fitted to achieve the adsorption effect. When the extrusion component 3 presses down, the adsorption plate 25 will be under force. During the process of the adsorption plate 25 being under force, the telescopic rod 23 will slide down around the adsorption chamber 21. While sliding down, the spring 24 will deform. As the adsorption plate 25 slides down, the sliding chamber 22 will slide down inside the adsorption chamber 21. A soft layer is provided between the sliding chamber 22 and the adsorption chamber 21 to prevent gas leakage. Through the combined use of the adsorption chamber 21, the sliding chamber 22 and the telescopic rod 23, the fabric 5 can be stably adsorbed, ensuring that the fabric 5 will not fall off or move during the processing.

[0050] A transmission rod 210 is fixedly connected to the lower part of the adsorption chamber 21. A long contact column 211 is fixedly connected to the transmission rod 210. A middle contact column 212 is installed below the long contact column 211. A short contact column 213 is installed below the middle contact column 212. When the adsorption chamber 21 is pushed by the hydraulic rod 13, it drives the transmission rod 210 to slide together. While the transmission rod 210 slides, it drives the long contact column 211, the middle contact column 212 and the short contact column 213 to move together.

[0051] The extrusion assembly 3 includes a support wall 31 fixed to the processing table 1. A pneumatic rod 32 is fixedly connected above the support wall 31, and a lower pressure plate 33 is fixedly connected below the pneumatic rod 32 for adsorbing the fabric 5 to slide downwards. The lower part of the lower pressure plate 33 abuts against the adsorption plate 25. Through the downward pressure of the lower pressure plate 33 on the adsorbed fabric 5, the contact between the two layers of fabric 5 can be ensured to be tight and uniform, avoiding loosening or gaps between the fabric 5 during processing, thereby improving the stability and consistency of processing quality. Through the action of the pneumatic rod 32 and the lower pressure plate 33, the fabric 5 can be evenly stressed during processing, avoiding damage or breakage caused by excessive local pressure, and also protecting the surface of the processing table 1 from wear and scratches caused by the fabric 5 in contact with the machinery.

[0052] The molding component 4 includes a semi-circular rail 41 located in the middle of the processing table 1. A first suction hole 42 is provided above the semi-circular rail 41, a second suction hole 43 is provided in the middle of the semi-circular rail 41, and a rear suction hole 44 is provided below the semi-circular rail 41. By sequentially suctioning air through the first suction hole 42, the second suction hole 43, and the rear suction hole 44, the fabric 5 can be effectively adsorbed into the semi-circular rail 41. The fabric 5, which is gradually squeezed towards the middle semi-circular rail 41 by the adsorption plate 25, is first adsorbed by the first suction hole 42, and then gradually adsorbed by the second suction hole 43 and the rear suction hole 44 in sequence, effectively adsorbing the fabric 5 into the semi-circular rail 41, so that the adsorbed fabric 5 forms a round arch shape, which facilitates subsequent processing.

[0053] Each of the first suction port 42, the second suction port 43, and the last suction port 44 is equipped with a connecting pipe 45, and each connecting pipe 45 is fitted with a one-way valve 46. The connecting pipe 45 is connected through a suction pipe 47, which is equipped with a top valve stem 48 for opening the one-way valve 46. There are three top valve stems 48, each corresponding to one of the three connecting pipes 45. The top valve stem 48 on the first suction port 42 corresponds to the long contact post 211, the top valve stem 48 on the second suction port 43 corresponds to the middle contact post 212, and the top valve stem 48 on the last suction port 44 corresponds to the short contact post 213. The different top valve stems 48... 8. The valves engage sequentially, opening each one-way valve 46 in turn, thereby opening the first suction port 42, the second suction port 43, and the last suction port 44 in sequence. This design allows for separate control of the suction in different areas, adapting to the different forms of different fabrics 5 during processing. It provides greater flexibility and adjustability in actual operation. Through this structural design, the connections between each suction port, adapter pipe 45, and suction pipe 47 can be easily disassembled and maintained. When replacement or cleaning is required, it can be easily operated, reducing the difficulty and workload of maintenance.

[0054] Working principle:

[0055] First, place the fabric 5 on the adsorption plates 25 on both sides above the processing table 1. Then, the adsorption holes 26 on the adsorption plates 25 begin to adsorb the fabric 5. Then, start the hydraulic rod 13, which pushes the adsorption chamber 21 to slide towards the center in the slide groove 11 through the slider 12. During the sliding process, the adsorption chamber 21 drives the transmission rod 210 to slide together as the hydraulic rod 13 pushes it. At the same time as the sliding, the long contact column 211, the middle contact column 212 and the short contact column 213 move together.

[0056] As the hydraulic rod 13 pushes the adsorption chamber 21 and the long contact column 211, the middle contact column 212 and the short contact column 213 on the lower transmission rod 210 to move together, the long contact column will first hit the top valve rod 48. The top valve rod 48 hit by the long contact column will open the corresponding one-way valve 46. At the same time, the first suction hole 42 on the semi-circular rail 41 will start to suck in air, and the fabric 5 squeezed by the adsorption plate 25 into the middle will be adsorbed into the semi-circular rail 41 first.

[0057] As the hydraulic rod 13 continues to push the adsorption chamber 21 and the long contact column 211, the middle contact column 212 and the short contact column 213 on the lower transmission rod 210, the middle contact column 212 will hit the next valve rod 48, and at the same time it will open the corresponding one-way valve 46. At this time, the secondary suction hole 43 on the semi-circular rail 41 will start to suck in air, adsorbing the fabric 5 that the adsorption plate 25 is continuously squeezing in the middle, so that the fabric 5 can be kept fixed in the semi-circular rail 41.

[0058] At this time, the hydraulic rod 13 continuously pushes the adsorption chamber 21 and the long contact column 211, the middle contact column 212 and the short contact column 213 on the lower transmission rod 210 to move until the hydraulic rod 13 reaches its limit position. At this time, the short contact column 213 opens the corresponding one-way valve 46 through the top valve rod 48. At this time, the rear air intake hole 44 on the semi-circular rail 41 starts to draw air. At this time, the cloth 5 squeezed towards the middle by the adsorption plate 25 can cover the inside of the semi-circular rail 41.

[0059] Finally, the extrusion assembly 3 is activated. The air pressure rod 32 on the extrusion assembly 3 drives the lower pressure plate 33 and the fabric 5 attached to the lower pressure plate 33 to be extruded onto the adsorption plate 25. The two layers of fabric 5 are bonded together. At the same time, a reinforcing rope is inserted into the semicircle formed by the lower layer of fabric 5 to reinforce the base of the canvas bag.

[0060] During the process of the pressure plate 33 pressing down on the adsorption plate 25, the adsorption plate 25 is subjected to force, which drives the telescopic rod 23 to slide down around the adsorption chamber 21. While sliding down, the spring 24 is deformed. As the adsorption plate 25 slides down, the sliding chamber 22 slides down inside the adsorption chamber 21. When the adsorption plate 25 is pressed to its limit, the support rod 27 will be inserted into the adsorption hole 26 so that the pressure plate 33 can squeeze the fabric 5 located at the adsorption hole 26, preventing gaps between the two layers of fabric 5 and improving the overall strength.

[0061] By sequentially opening the first suction hole 42, the second suction hole 43, and the third suction hole 44, the fabric 5, which is gradually squeezed inward by the suction plate 25, is sequentially adsorbed into the semi-circular rail 41. The cooperation of each suction hole ensures that the fabric 5 is completely fitted into the interior of the semi-circular rail 41, facilitating subsequent processing. When the fabric 5 on the suction plate 25 is pressed down and bonded to another layer of fabric 5 by the pressure plate 33, the fabric 5 located at the suction hole 26 is supported by the support rod 27, ensuring that the fabric 5 in this pressure bonding blind zone is evenly bonded to the fabric 5 on the pressure plate 33, preventing uneven bonding.

[0062] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0063] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
