Description

Technical Field

[0001] The utility model belongs to the technical field of sewing equipment, and in particular relates to a horizontal sewing machine group. Background Art

[0002] Sewing is mainly a process of sewing and wrapping cloth, leather and other products through sewing machines to achieve partial assembly of products. In the production of shell products, taking bags as a reference, it is necessary to sew the outer cloth, lining cloth, zipper, etc. to combine them with the product body to obtain the required product.

[0003] At present, luggage processing manufacturers usually choose ZS-1341 computer direct-drive high-head sewing machines. When using this type of sewing machine to sew the lining and zippers of luggage, the luggage is hung on the round head under the sewing machine head. Due to the gravity of the luggage itself, its lower part will always tilt toward the side of the sewing machine body. Therefore, it is necessary to manually support the luggage body to complete the sewing, and it is also necessary to manually rotate the luggage at the corner to complete the flipping of the luggage. Smaller suitcases weigh about 3kg, and heavier ones can reach 5kg. Each flip and lift will generate a huge load for the workers. In addition, the sewing equipment is prone to skewed seams during use, which directly affects product quality.

[0004] The utility model patent with publication number CN216514527U discloses a luggage sewing device, including a sewing machine, a placing table, a sewing needle cylinder, a pressing sheet and luggage. The device hangs the luggage on the placing table and moves the luggage to achieve single-side sewing of the luggage. By observing the drawings of the document, it can be seen that the device can only sew on one side, and the sewing of each side requires adjusting the direction of the luggage. Although the pressing sheet can ensure that the single-side wiring will not shake violently to a certain extent, the luggage needs to be removed and re-fixed after adjusting the direction each time the direction is changed, which will undoubtedly reduce production efficiency and make it unsuitable for mass production. In addition, there are also problems with how the device aligns the wiring at the corners.

[0005] In summary, we have designed a sewing machine that can make the sewing machine run smoothly and evenly on shell-shaped products such as bags without affecting the working efficiency of the sewing equipment, and can effectively reduce the work intensity of workers. Summary of the invention

[0006] The utility model aims to provide a horizontal sewing machine set to solve the problem that the existing sewing machine mentioned in the background art is prone to skewed seam lines during the sewing process of the shell and the overturning and lifting will cause great load on the workers.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes a sewing machine body and a horizontally arranged placement platform, the needle of the sewing machine body is horizontally arranged and moves in the horizontal direction, a positioning seat is fixed on the sewing machine body, the end of the positioning seat is placed above the top surface of the placement platform, and a shuttle used in conjunction with the needle is provided on the positioning seat, and the positioning seat is used to fit the inner wall of the product close to the needle on the sewing machine body to position one side of the product.

[0008] Preferably, a frame is provided below the placement platform, a lifting assembly is fixed on the frame, the placement platform is placed on the lifting assembly, and the lifting assembly is used to adjust the position of the placement platform in the vertical direction.

[0009] Preferably, the positioning seat is arranged to penetrate the placing platform from the bottom of the placing platform, and the placing platform has a through groove penetrating it from the top surface downward on one side edge thereof, and the through groove also penetrates the side wall of the side edge of the placing platform, and the positioning seat can be translated from the edge of the placing platform into the through groove.

[0010] Preferably, there is a passage between the through groove and the sewing machine body for accommodating a human forearm to enter, and the passage is located on a side in front of the sewing line of the product in the direction of product travel.

[0011] Preferably, the surface of the positioning seat that contacts the inner wall of the product is a convex surface.

[0012] Preferably, the sewing body includes a machine head, a clamping foot, a clamping plate and a needle module, the clamping foot is horizontally installed on the machine head, the clamping plate is fixed on the positioning seat and cooperates with the clamping foot to pre-clamp the side wall of the product, and the needle module is horizontally arranged on the machine head and can make the needle extend and retract in the horizontal direction.

[0013] Preferably, a travel drive block is provided on the machine head, and a travel presser foot is horizontally installed on the travel drive block, and the travel presser foot can be extended and retracted in the direction of needle movement. The travel drive block drives the travel presser foot to reciprocate in the direction of product travel, and the positioning seat is provided with a travel slider which can reciprocate simultaneously with the travel presser foot in the direction of product travel and cooperate with the travel presser foot to tighten the side wall of the product.

[0014] Preferably, the surface of the splint that fits against the inner wall of the product is a convex surface, and the surface of the traveling slider that contacts the product is a convex surface.

[0015] Compared with the prior art, the utility model provides a horizontal sewing machine unit, which has the following beneficial effects:

[0016] The utility model is based on the original equipment by arranging a placement platform and placing the shell-shaped object to be processed such as the product on the placement platform, and then completing the sewing of the object to be processed by moving the object to be processed. When in use, since the surface of the positioning seat that contacts the inner wall of the product is a convex surface, it is convenient for the product to be bent at the corner. In this process, since the object to be processed can be stably placed on the placement platform, the sewing machine can run the line on it smoothly and evenly. At the same time, the worker only needs to move the object to be processed horizontally, which can effectively reduce the labor intensity of the worker. Among them, the height of the placement platform in the vertical direction is controlled by the lifting component, so that the different positions of the sewing thread on the product can be conveniently adjusted, so as to be applied to the sewing requirements of different heights of the product, and ensure the product The product will always be placed stably on the placement platform, and will not shake due to the height difference between the seam line and the placement platform. The channel for accommodating the forearm on the placement platform can facilitate the workers to make overall adjustments to the lining of the product before sewing, thereby reducing the rate of inferior products. In addition, in the sewing machine body, since the travel drive block can drive the travel presser foot to reciprocate in the travel direction of the product, the product can be automatically advanced through its cooperation with the travel slider, further reducing the labor intensity of the workers. Such a structural setting can effectively solve the problem that the seam line is easily skewed when sewing shell-shaped products on the existing sewing machine, and the flipping and lifting will cause a great load on the workers.

[0031] The working principle and use process of this utility model:

[0032] When using the device to sew products, products such as bags are buckled on the placement platform 2 so that the products cover the positioning seat 3 therein, and the height of the placement platform 2 suitable for the product is determined by adjusting the lifting component 5, and then the side wall of the product is inserted between the clamping foot 17 and the clamping plate 18 for pre-tightening (this step is the basic step of the sewing machine), and then the sewing machine body 1 is started. During the operation of the sewing machine needle module 12, the traveling presser foot 14 and the traveling pressure block will clamp the side wall of the product to make it move forward, and then release the product to return to the initial position and repeat this process. The movement frequency of the slider 16 is fixed, so the stitches on the product will be very uniform. At the same time, because the product can be placed stably on the placement platform 2, the sewing machine body 1 can run smoothly on it. During the movement of the product, the worker only needs to translate the object to be processed, which can effectively reduce the physical strength consumed by the worker. In addition, during the movement of the product, the position between the fabric and the product can be adjusted in time through the channel on the through groove 21 to ensure that the sewing requirements are met. The above structural arrangement can effectively solve the problem that the sewing processing of the shell of the existing sewing machine is prone to skewed stitches and the flipping and lifting will cause a great load on the workers.
