When splicing fabrics, first align the splicing seams of the two pieces of fabric, and complete the sewing and splicing during the movement of the fabrics.

[0003] However, some devices on the market can only sew and cannot automatically adjust the splicing seam. The splicing seam deviates, and manual correction is required during the sewing process, resulting in poor automation.

[0004] For example, Chinese Patent Application No.: CN202021554071.3, a fabric splicing and sewing device, includes a sewing device body. The sewing device body includes a base plate, a chassis, a sewing needle drive chassis, and a sewing mechanism. The chassis is fixedly connected to the right side of the top of the base plate. The sewing needle drive chassis is fixedly connected to the top of the chassis. The sewing mechanism is movably installed on the left side of the bottom of the sewing needle drive chassis. Compression control mechanisms are arranged at the front end and the rear end of the bottom of the sewing needle drive chassis. Positioning telescopic mechanisms are arranged on the front and back of the top of the base plate. A pressing cylinder is arranged on the front of the sewing mechanism. When this fabric splicing and sewing device works, the pressing cylinder presses two pieces of fabric, and then the sewing machine sews the fabric. That is, during the sewing process of this splicing and sewing device, the splicing seam needs to be manually adjusted, and its automation is poor. Summary of the Utility Model

Specific embodiments

[0028] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the attached drawings and preferred embodiments, details the specific embodiments, structures, features, and their effects according to the present utility model as follows.

[0029] Embodiment 1

[0030] Please refer to Figures 1 to 4 shown, which shows the specific structure of the first preferred embodiment of the present utility model, and is a seam joining machine.

[0031] Among them, when the fabric 43 passes through the seam joining component 40, the first piece of fabric 43 passes through the first material passing channel 41, the second piece of fabric 43 passes through the second material passing channel 42, the fabrics 43 are stacked up and down and automatically aligned with the splicing seam, and then the sewing machine 10 uses double needles to sew the two pieces of cloth together, and its working efficiency is higher.

[0032] A sewing machine of the present application includes a first conveyor belt 25 and a second conveyor belt 26; a sewing machine 10 is arranged between the first conveyor belt 25 and the second conveyor belt 26, and the sewing machine 10 has at least one sewing needle 11; a material dragging mechanism 20 is arranged beside the first side of the sewing machine 10, and the material dragging mechanism 20 can drag the material forward; a detachable sewing joint component 40 is arranged beside the second side of the sewing machine 10; the sewing joint component 40 is bent to form a first material passing channel 41 and a second material passing channel 42, the first material passing channel 41 and the second material passing channel 42 are arranged up and down, and the opening directions of the first material passing channel 41 and the second material passing channel 42 are opposite. The first conveyor belt 25 and the second conveyor belt 26 have a certain width to convey large-sized fabrics 43. In this embodiment, there are two sewing needles 11, and two fabrics 43 are sewn and joined simultaneously. When the fabrics 43 are joined, the material dragging mechanism 20 drags the material forward. The two fabrics 43 are placed on the first conveyor belt 25, then the joining edge of the first fabric 43 passes through the first material passing channel 41, and the joining edge of the second fabric 43 passes through the second material passing channel 42. When the two fabrics 43 come out of the sewing joint component 40, their joining seams overlap and are then sewn together by the sewing needles 11 of the sewing machine 10. Therefore, this type of sewing machine can automatically align the fabrics 43 and sew them together, with higher working efficiency and automation level.

[0033] The midline between the two sewing needles 11 coincides with the midlines of the first material passing channel 41 and the second material passing channel 42. When the upper and lower fabrics 43 are joined, the midline between the two sewing needles 11 coincides with the midlines of the first material passing channel 41 and the second material passing channel 42. This design makes the stress of the joining seam better and the centering more beautiful.

[0034] The sewing joint component 40 of this embodiment is made of metal by bending, and its inner wall is smooth with very little friction. The height of the first material passing channel 41 is smaller than the height of the second material passing channel 42. This design is beneficial for the sewing joint component 40 to obtain better elasticity and better support.

[0035] Preferably, the material dragging mechanism 20 includes a first pressing wheel 22 and a second pressing wheel 24. The rotatable first pressing wheel 22 is arranged on the first linear module 21, and the first linear module 21 drives the first pressing wheel 22 to press against the second pressing wheel 24. The first conveyor belt 25, the second conveyor belt 26, and the first pressing wheel 22 move synchronously, which is beneficial to ensuring the working coordination. The first pressing wheel 22 and the second pressing wheel 24 are rotatable, and preferably rubber wheels are used. The first pressing wheel 22 presses against the splicing seam position of the fabric 43 on the second pressing wheel 24. The first pressing wheel 22 and the second pressing wheel 24 jointly press the splicing seam position of the two pieces of fabric 43 and at the same time drag the fabric 43 forward. The cooperation between the first pressing wheel 22 and the second pressing wheel 24 can also control the advancing direction of the fabric 43, and the fabric 43 will not deviate. The first linear module 21 drives the first pressing wheel 22 to move up and down. The first linear module 21 is a cylinder module or a lead screw module driven by a servo motor.

[0036] Preferably, the first pressing wheel 22 has two spaced-apart rims 23, and the rims 23 press on the splicing seam position. The rims 23 press on the splicing seam position where the two pieces of fabric 43 overlap. This design can control the splicing position of the two pieces of fabric 43 and has a good control effect on the splicing quality and the movement direction of the fabric 43.

[0037] Preferably, the first pressing wheel 22 is connected to the driving mechanism 30; the driving mechanism 30 includes a transmission shaft 31 and a synchronous pulley 32. Universal couplings 33 are arranged at both ends of the transmission shaft 31. The first universal coupling 33 is connected to the output end of the motor of the sewing machine 10, and the second universal coupling 33 is connected to the first synchronous pulley 32. A first synchronous belt is sleeved between the two synchronous pulleys 32, and the first pressing wheel 22 is arranged on the second synchronous pulley 32. A second synchronous belt is connected between the output end of the motor and the gearbox 34. The power of the motor is transmitted to the gearbox 34 through the second synchronous belt. The gearbox 34 transmits the power in sequence from the first universal coupling 33 → the transmission shaft 31 → the second universal coupling 33 → the synchronous pulley 32. The synchronous pulleys 32 transmit power through the first synchronous belt. When the synchronous pulley 32 rotates, the first pressing wheel 22 rotates synchronously. The universal coupling 33 facilitates the up and down movement of the first pressing wheel 22.

[0038] Preferably, retaining strips 27 are arranged on both sides of the first conveyor belt 25 and the second conveyor belt 26. A control switch 14 and a touch screen 13 are arranged beside the sewing machine 10. The retaining strips 27 can prevent the fabric 43 from falling. The control switch and the touch screen facilitate the operation of the equipment by the workers.

[0039] Embodiment 2

[0040] Please refer to Figures 5 - 6It is the specific structure of the second embodiment. Preferably, the seam joining component 40 is arranged on the quick-release mechanism 50, and the quick-release mechanism 50 includes a base 51 and a mounting seat 52; the mounting plate 44 of the seam joining component 40 is arranged on the base 51; the first fastener 53 passes through the mounting plate 44 and the mounting seat 52 and fastens the mounting seat 52 and the base 51 together. The base 51 and the mounting seat 52 are penetrated by a long and narrow mounting hole 54, and the first fastener 53 passes through the mounting hole 54. The seam joining component 40 can be quickly installed and disassembled on the workbench of the sewing machine through the quick-release mechanism 50. The first fastener 53 is preferably a screw. The base 51 and the mounting seat 52 clamp the mounting plate 44 of the seam joining component 40, and then the first fastener 53 fastens the base 51 and the mounting seat 52 together to complete the installation of the seam joining component 40. The mounting plate 44 is provided with holes through which the first fastener 53 can pass and can be used for installation. The mounting hole 54 is long and narrow, and the position of the seam joining component 40 can be adjusted. Just loosen the first fastener 53 to adjust.

[0041] Preferably, iron plates are arranged on the inner sides of the first conveyor belt 25 and the second conveyor belt 26, and the magnets are adsorbed on the iron plates. When the fabric is placed on the first conveyor belt 25 and the second conveyor belt 26, the magnets are placed on the fabric. Since the magnets can adsorb the iron plates, the cooperation of the magnets and the iron plates can prevent the fabric from running off.

[0042] Preferably, the operating table 12 provided beside the sewing machine is provided with a control panel, and a control switch 14 is arranged on the control panel. A remote controller 13 is arranged beside the first conveyor belt 25 and / or the second conveyor belt 26, and the remote controller 13 is connected to the control panel. The control panel supports wireless communication, such as Bluetooth, infrared, wifi, etc. The remote controller 13 can be an infrared remote controller, a WiFi remote controller, a Bluetooth remote controller, etc. The worker can manually operate the control switch 14 or communicate with the control panel through the remote controller 13 to control the folding sewing machine, for example, operations such as forward, backward, sewing, etc. The remote controller 13 makes it more convenient for the worker to operate the folding sewing machine.
