Description

Technical Field

[0001] The utility model relates to the technical field of production and processing in the home textile industry, in particular to an automatic sewing machine for fabric sheets used in home textiles. Background Technique

[0002] Household textiles are also called decorative textiles. Home textiles include curtains, fabrics, cushions, beddings, carpets, bath towels, kitchen textiles, bed liners, bedspreads, mosquito nets, cool mats, quilts, blankets, throw pillows, etc. Household textiles, together with clothing textiles and industrial textiles, constitute the three major parts of the textile industry. As an important category of textiles, household textile products are called "soft decorations" in the home decoration matching. It plays a decisive role in creating the environment. It has come all the way from the traditional daily life needs of covering, concealing, and washing. Today's home textile industry has already had a consumption style with multiple functions such as fashion, personality, and health care. The household textile industry in the textile industry is gradually becoming the new favorite in home decoration and space decoration.

[0003] To combine two or more fabric sheets together, a sewing process is required. In the prior art, the most widespread method is manual sewing. Therefore, the textile industry has always been a labor-intensive industry, with low efficiency, low output value, and high cost. On the other hand, the manual processing method will inevitably lead to low consistency of this product and an increase in the defective rate, unable to meet the requirements of large-scale production.

[0004] In order to change the current situation of manual sewing, some automated devices have emerged. Referring to the patent document CN211645594U, a warpage-proof sewing device for sewing pieces is disclosed, which includes a frame, a sewing device, a sliding device, and a scale plate. The sliding device includes a sliding table and a sliding driver. The sliding driver is installed on the frame and its output end is connected to the sliding table. The sliding driver drives the sliding table to slide on the frame. The sewing device is installed on the frame and includes a sewing driver, a sewing needle, and a pressing member. The pressing member is located directly below the sewing needle. The output ends of the sewing driver are respectively connected to the sewing needle and the pressing member. While the sewing driver drives the pressing member to perform reciprocating up and down movements, it also drives the sewing needle to pass through the pressing member to perform synchronous reciprocating up and down movements. The scale plate can selectively press or move away from the fabric placed on the sliding table. The scale plate is provided with a positioning hole for placing the sewing piece, and several positioning marking structures are provided at at least one side of the positioning hole. The warpage-proof sewing device for sewing pieces of the present invention has the advantages of good versatility and wide processing range. However, in practical applications, this patented technology has many defects. For example: 1. The shape of the pressing member is fixed and there are certain distance requirements for the pressing member. When the fabric to be sewn is small, the pressing member will not be able to contact the fabric sheet, resulting in no limiting function and the inability to achieve the sewing function; 2. The area where the fabric sheet is pressed by the pressing member is necessarily unable to be sewn; 3. The drawings and content shown in the patent are relatively simple and cannot be directly replicated and implemented. Summary of the Invention

[0044] Embodiment 1

[0045] Refer to Figures 1 to 8 , an automatic sewing machine for fabric sheets 6 used in home textiles, comprising:

[0046] A workbench 1, on which an electric control device is provided, and the electric control device forms a control connection with each electrical component;

[0047] Two reciprocating motion mechanisms 2, which are symmetrically distributed on the workbench 1, and a sewing work area 21 is formed between the two reciprocating motion mechanisms 2;

[0048] The simulated articulated arm mechanism 3 has two groups and is movably arranged on the two reciprocating motion mechanisms 2 respectively;

[0049] The sewing machine 4 is assembled on the workbench 1 and arranged between the two simulated articulated arm mechanisms 3 .

[0050] The above content is the basic structural scheme of the utility model. It should be particularly noted that a simulation joint arm mechanism 3 is used to simulate the effect of human hands and the function of hand pressing. Furthermore, there are two groups of simulation joint arm mechanisms 3, which simulate the effect of simultaneous pressing of the left and right hands during manual sewing, and form a multi-point pressing effect, which is more flexible and reliable. On the other hand, the relative position of the sewing machine 4 in the utility model is fixed to ensure its stable operation. At the same time, after the reciprocating motion mechanism 2 is started, it drives the simulation joint arm mechanism 3 to reciprocate, so that the simulation joint arm mechanism 3 can simulate the effect of human hands dragging the textile sheet forward and backward to realize the switching function of the sewing position.

[0051] Preferably, each group of the simulated articulated arm mechanism 3 has at least two articulated arm unit components 31. Each articulated arm unit component 31 can be regarded as simulating the effect of one finger in this solution. Therefore, when there are two or more articulated arm unit components 31, the effect of multiple fingers pressing and positioning the fabric sheet 6 at the same time can be simulated, so as to achieve a better effect.

[0052] On the basis of the above preferred scheme, the specific composition scheme of the joint arm unit assembly 31 is as follows: the joint arm unit assembly 31 includes a sliding seat 311, a rotatable joint support element 312 and a positioning rod 313. The sliding seat 311 is transmission-connected to the reciprocating mechanism 2, so that the movement of the reciprocating mechanism 2 can move the sliding seat 311. The joint support element 312 is fixed to the front end of the sliding seat 311, and the positioning rod 313 is fixed to the front end of the sliding seat 311, and the positioning rod 313 is tilted downward. The structure of the above joint arm unit assembly 31 is adopted to simulate the posture of the finger when pressing.

[0053] Furthermore, the lower end of the positioning rod 313 also has a soft rubber pad 314, which simulates the elasticity of fingers and can also adaptively press the cloth sheets 6 of different materials and thicknesses, while also having a buffering and protective function without causing damage to the cloth sheets 6.

[0054] In some preferred embodiments of the present utility model, a ball head groove 3141 is provided in the soft rubber cushion block 314. The lower end of the positioning rod 313 has a ball head end 3133, and the ball head end 3133 is embedded in the ball head groove 3141 to form an interference fit. Through the cooperation between the ball head end 3133 and the ball head groove 3141, a ball head fitting structure is formed between the positioning rod 313 and the soft rubber cushion block 314, which can withstand loads in various directions and angles. The main advantage is that there is better structural flexibility between the two. It can rotate within a plane, thereby providing greater flexibility and freedom, which is very useful in applications that require a large range of motion. And it is easy to install and adjust. The ball head structure is usually designed to be easy to install and adjust, which makes it more convenient during installation or maintenance.

[0055] Human fingers, each finger consists of three phalanges. Except for the thumb, other fingers have proximal phalanges, middle phalanges, and distal phalanges, and can rotate flexibly with each other to achieve the straightening or bending actions of the fingers. In order to better simulate the action effect of the fingers and make the movement of the joint support element 312 more flexible, specifically: the joint support element 312 includes a first support 3121, a second support 3122, and a third support 3123; the first support 3121 is fixed at the front end of the sliding seat 311; the second support 3122 is hinged at the front end of the first support 3121, and the second support 3122 is inclined upward; the third support 3123 is hinged at the front end of the second support 3122, and the third support 3123 is inclined downward.

[0056] In some preferred solutions of the present utility model, a heightening support frame 5 is provided on the workbench 1, and the reciprocating motion mechanism 2 is mounted on the heightening support frame 5. The height of the heightening support frame 5 is adjustable, so that a certain distance 5d is formed between the reciprocating motion mechanism 2 and the workbench 1. Furthermore, the spacing between the simulation joint arm mechanism 3 and the workbench 1 support is also 5d, meeting the requirements of each component for installation space and use space, and simulating a real working environment.

[0057] Embodiment Two

[0058] Based on the structure of Embodiment One, the preferred transmission structure between the simulation joint arm mechanism 3 and the reciprocating motion mechanism 2 is: Refer to Figures 4 to 6, the sliding seat 311 includes a seat body 3111 and a plurality of pulleys 3112 provided on the seat body 3111; the reciprocating motion mechanism 2 is a belt conveyor device, and the belt conveyor device has a conveyor belt, and the conveyor belt is arranged between a plurality of pulleys 3112, so that the belt conveyor device and the sliding seat 311 form a transmission cooperation. The transmission structure of the belt conveyor device and the pulley 3112 has many advantages. First, the transmission is more efficient. The belt conveyor device can continuously convey materials without interruption, thereby improving production efficiency. Second, it is relatively safe during operation. Third, it has reliability. The belt conveyor device has a simple structure, a low failure rate, and is relatively easy to maintain. Fourth, it is more flexible and can be customized in length, angle and shape according to needs to meet different process requirements.

[0059] Embodiment III

[0060] Based on any of the foregoing embodiments, a more preferred solution of the present application is: Refer to Figures 7 to 8 , the positioning rod 313 is a two-stage telescopic rod to realize the telescopic function of the positioning rod 313, so as to simulate the telescopic effect when the finger presses the fabric sheet 6 during work.

[0061] More specifically, the two-stage telescopic rod includes a fixed rod 3131 and a movable rod 3132. An activity cavity 3134 is formed in the fixed rod 3131. At least part of the movable rod 3132 is inserted into the activity cavity 3134 from front to back. A seal 3135 is provided between the movable rod 3132 and the inner wall of the activity cavity 3134, and the rear end of the activity cavity 3134 is connected to an external driving air source through an air pipeline 3136. During work, when the external driving air source increases the pressure in the activity cavity 3134 (positive pressure) through the air pipeline 3136, the movable rod 3132 is pressed and extends outward relative to the fixed rod 3131, simulating the action of the finger extending outward; when the external driving air source reduces the pressure in the activity cavity 3134 (negative pressure) through the air pipeline 3136, the movable rod 3132 is pressed and retracts inward relative to the fixed rod 3131, simulating the action of the finger retracting backward.

[0062] It should be noted that other technical solutions of the present invention all belong to the prior art, so they will not be elaborated.

[0063] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
