[0001] The utility model relates to the technical field of cloth bag sewing devices, and more specifically, to a device capable of sewing double-layer cloth bags. Background Art

[0002] In the field of clothing and accessories manufacturing, cloth bags are a common packaging or decorative element, and their market demand is becoming increasingly diverse. Traditionally, cloth bags are made of thin fabrics and can be completed through simple cutting and sewing processes. However, with the evolution of fashion trends and changes in consumer preferences, cloth bags made of thick fabrics are gradually favored by the market due to their unique texture and durability. Thick fabric bags not only enrich the product variety, but also enhance the added value of the products.

[0003] However, the forming and sewing process of thick fabric bags is more complicated than that of thin fabric bags. Traditional bag making equipment is mainly designed for thin fabrics and is difficult to adapt to the pressure and precision requirements required for thick fabrics during the forming process. Therefore, the forming and sewing of thick fabric bags mostly rely on manual operations, which not only leads to low production efficiency, but also increases labor costs, and it is difficult to ensure product consistency and quality stability.

[0004] Specifically, when making thick cloth bags manually, it is necessary to fold, press creases and sew them precisely, which is not only labor-intensive but also easily affected by human factors, resulting in a high defective rate. In addition, with the increase in market demand, manual production can no longer meet the needs of large-scale production.

[0005] In order to solve the above problems, the market urgently needs an automated equipment that can efficiently and accurately complete the forming and sewing of thick cloth bags. The equipment needs to be able to simulate all aspects of manual operation, including the pressing of cloth folds, the forming of cloth bags and the final sewing, and it also needs to have a high degree of automation and stability to ensure the consistency and quality of the products.

It should be understood that the purpose of the following implementation methods is to make the technical solution of the present invention clearer and easier to understand, and does not limit the protection scope of the claims.

[0037] The present invention will be further described below through specific embodiments.

[0038] Example

[0039] This embodiment provides a device for sewing double-layer cloth bags, such as Figure 1-8 As shown, it includes a platform assembly and a knife pressing assembly, the platform assembly includes a frame 10, an operating table 20, and a mold mechanism 30, the operating table 20 is arranged on the frame 10, the mold mechanism 30 is installed on the frame 10, and cooperates with the operating table 20 to complete the production of double-layer cloth bags;

[0040] The mold mechanism 30 includes a first mold plate 31 and a second mold plate 32. The first mold plate 31 is smaller than the second mold plate 32 and is stacked on the second mold plate 32. The first mold plate 31 is connected to a first cylinder 34 via a first connecting plate 33, and the second mold plate 32 is connected to a second cylinder 36 via a second connecting plate 35. The second cylinder 36 is used to push the second mold plate 32 to move upward, and the first cylinder 34 is used to pull the first mold plate 31 to move downward.

[0041] The knife pressing assembly includes a knife holder 40, a first laminating knife 41, and a second laminating knife 42. The first laminating knife 41 is installed on the knife holder 40 through a first knife pressing cylinder 43. The first laminating knife 41 can cooperate with the first template 31 to press the folds on the upper layer of the bag. The second laminating knife 42 is installed on the knife holder 40 through a second knife pressing cylinder 44. The second laminating knife 42 can cooperate with the second template 32 to press the folds on the lower layer of the bag.

[0042] The operation mode is as follows: the clothing fabric is laid on the operating table 20, the bag fabric is laid on the first template 31, the knife holder 40 is moved to the vicinity of the mold mechanism 30 through the first moving mechanism, and the first laminating knife 41 presses the upper layer folds of the bag toward the first template 31;

[0043] Then, the second template 32 moves upward, lifting the bag material and moving it toward the first template 31 to form a bag groove;

[0044] Afterwards, the second laminating knife 42 moves toward the second template 32 to press the folds of the lower layer of the bag; (the gullies of the bag are the folds formed between the folds of the upper layer and the folds of the lower layer) at this point, the creasing operation is completed;

[0045] The first template 31 and the second template 32 move toward the operating table 20 below under the pull of the first cylinder 34, and the tool holder 40 moves downward following the first template 31 and the second template 32, and compresses the first template 31 and the second template 32 onto the operating table 20. At this time, the shape of the cloth bag is basically formed, and the tool holder 40 moves to a position away from the mold mechanism 30 through the first moving mechanism;

[0046] Afterwards, the mold mechanism 30 is pulled out of the cloth bag through the second moving mechanism, and the cloth bag and the clothing fabric are pressed by the shaping mechanism. The shaping mechanism transports the cloth bag and the clothing fabric to the sewing device through the third moving mechanism, and the sewing device sews the lower layer folds to the clothing fabric.

[0047] The utility model is suitable for forming and sewing thick cloth bags. The upper folds of the cloth bag are formed by the cooperation of the first laminating knife 41 and the first template 31, and the grooves of the cloth bag edge are formed by the support of the second template 32. Then, the lower folds of the cloth bag are formed by the cooperation of the second laminating knife 42 and the second template 32. Thus, the overall forming of the thick cloth bag is completed, which has the advantages of high production efficiency and good forming effect. In traditional technology, thin cloth is usually used as the cloth bag material. With the rising enthusiasm of people to design new styles of clothes and the needs of the market, thick cloth bags are gradually showing a trend of high demand. However, the previous equipment can only form thin cloth. Thick cloth bags are usually formed and sewn manually. Due to the defects of high manual operation cost, low efficiency, high defective rate, etc., it is necessary to update the automation and mechanization. Therefore, the utility model designs a two-layer mold and a double-layer pressing knife equipment structure to meet the forming and sewing of cloth bags made of thick cloth as raw materials.

[0048] Specifically, the first laminating knife 41 includes a first end knife head 411, a first side knife head 412, and a first corner knife head 413; the first end knife head 411 is used to press the folds at the bottom of the upper layer of the cloth bag, the first side knife head 412 is used to press the folds at the side of the upper layer of the cloth bag, and the first corner knife head 413 is used to press the folds at the corners of the bottom of the upper layer of the cloth bag.

[0051] Specifically, a first electromagnet is disposed on the tool holder 40, and a second electromagnet is disposed on the operating table 20 corresponding to the first electromagnet. The compression strength of the cloth bag after the fold pressing is enhanced through the adsorption of the first electromagnet and the second electromagnet.

[0052] Specifically, the first moving mechanism, the second moving mechanism, and the third moving mechanism are all moving mechanisms with multi-dimensional motion. Such moving mechanisms all adopt the structure of conventional mechanical equipment and can realize the moving function of corresponding mechanical parts.

[0053] Specifically, the second laminating knife 42 includes a second end knife head 421, a second side knife head 422, and a second corner knife head 423; the second end knife head 421 is used to press the folds at the bottom of the lower layer of the cloth bag, the second side knife head 422 is used to press the folds on the side of the lower layer of the cloth bag, and the second corner knife head 423 is used to press the folds at the corners of the bottom of the lower layer of the cloth bag.
