Description

Technical Field

[0001] This application relates to the field of sewing machine technology, and in particular to a transmission structure for a gantry sewing machine. Background Technology

[0002] A gantry sewing machine is a special type of sewing machine, typically used for large-scale production in industrial environments. Its name comes from its structural feature, namely the gantry frame design, which provides a larger workspace and greater stability.

[0003] A fully automatic edge-sewing machine, publication number CN205368676U, is disclosed on the Chinese Patent Network. It includes a three-synchronous sewing machine head, an operation box, a machine head frame, a spring-loaded fabric pressing mechanism, an X-axis moving module, a gantry structure, a Y-axis drive rail, a frame structure, a table, and casters. Its key feature is that Y-axis drive rails are installed on both sides of the top of the frame structure, and a gantry structure is installed on the upper part of the two Y-axis drive rails. The gantry structure is a bridge-type structure that can move along the Y-axis drive rails. An X-axis moving module is installed on one side of the crossbeam at the top of the structure, and a spring-loaded fabric pressing mechanism is installed at the moving end of the X-axis moving module. The three-synchronous sewing machine head is installed on the top of the machine head frame, facing the X-axis moving module and corresponding to the spring-loaded fabric pressing mechanism. By controlling the movement of the sewn product in the XY plane, combined with the sewing of the three-synchronous sewing machine head, the sewing of the fabric edge is completed. During the sewing process, the operator does not need to manually participate in the operation, and no skilled operator is required, making it easy for beginners to start operating.

[0004] Because the sewing head and base are separate, and they need to move together in a certain direction to sew, errors in the accuracy of synchronous movement will lead to a reduction in sewing quality, affecting product output and product quality. The increase in defective products will directly reduce the product's competitiveness in the market, and the occurrence of defective products will also cause a waste of economic resources. Utility Model Content

[0005] This application provides a transmission structure for a gantry sewing machine to address the technical problem that the inventors recognized is that since the sewing head and base are separately set up and need to move together in a certain direction for sewing, errors in the accuracy of synchronous movement will lead to a reduction in sewing quality, affecting product output and product quality, increasing defective products, and thus directly reducing product competitiveness in the market. At the same time, the occurrence of defective products causes economic and resource waste.

[0006] This application provides a transmission structure for a gantry sewing machine, including a gantry frame. A first direction transmission assembly and a second direction transmission assembly are mounted on the gantry frame. The transmission directions restricted by the first and second direction transmission assemblies are perpendicular. The first direction transmission assembly includes a left fixed seat and a right fixed seat, both located on the front of the gantry frame. A rotating shaft is mounted on both the left and right fixed seats. The rotating shaft on the right fixed seat is connected to a connecting shaft, the other end of which is connected to a first transmission wheel. A driving component is mounted on the gantry frame, and the output end of the driving component is connected to two… The system includes a first transmission wheel and a second transmission belt, both of which abut against the surface of the first transmission belt. The rotating shafts on the left and right fixed seats abut against the surface of the second transmission belt. It also includes a mounting base and a clamping plate, both of which abut against the second transmission belt. The back of the mounting base and the front of the clamping plate are detachably connected. There are two of each of the following: a left fixed seat, a right fixed seat, a second transmission belt, and a mounting base. One mounting base has a detachable base connected to its top, and the bottom of the other mounting base has a detachable machine head connected to its bottom.

[0007] In any of the above technical solutions, the second direction transmission component further includes a transmission module, which is detachably connected to the front of the gantry frame, and a feeding block is provided on the top of the transmission module.

[0008] In any of the above technical solutions, one of the left fixed seat, the right fixed seat, the second transmission belt and the mounting seat are located above the transmission module, and one of the left fixed seat, the right fixed seat, the second transmission belt and the mounting seat are located below the transmission module.

[0009] In any of the above technical solutions, the connecting shaft further passes through the rotating shaft on the two right-side fixed seats.

[0010] In any of the above technical solutions, a slide rail is further provided on the gantry frame, and a slider is slidably connected on the slide rail, the front of the slider being detachably connected to the back of the mounting base.

[0011] In any of the above technical solutions, the number of clamping plates is further an integer multiple of the number of mounting bases.

[0012] In any of the above technical solutions, the machine head and the base are further arranged vertically.

[0013] In any of the above technical solutions, there is a gap between the machine head and the base.

[0014] In any of the above technical solutions, the number of slide rails and the number of sliders are both integer multiples of the number of mounting bases.

[0015] In any of the above technical solutions, the machine head and the base are detachably connected to the mounting base by bolts or screws.

[0016] The main benefits of this application are:

[0017] The mounting base and clamping plate are connected after contacting the second transmission belt, thus fixing the position of the mounting base. The machine head and base are installed on different mounting bases. The drive unit is activated to rotate the second transmission wheel, which in turn rotates the first transmission wheel via the first transmission belt. This causes the connecting shaft to rotate, and simultaneously the rotating shaft on the right fixed base rotates, thus synchronizing the movement of the two second transmission belts. This, in turn, causes the machine head and base to move synchronously, ensuring the consistency of the stitches and the uniformity of the sewing effect, thereby guaranteeing product quality and reducing economic and resource waste.

[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5One or more embodiments provide a transmission structure for a gantry sewing machine, including a gantry frame 100. A first direction transmission assembly and a second direction transmission assembly are provided on the gantry frame 100. The transmission directions restricted by the first and second direction transmission assemblies are perpendicular. The first direction transmission assembly includes a left fixed seat 101 and a right fixed seat 102, both located on the front of the gantry frame 100. A rotating shaft 103 is provided on both the left and right fixed seats 101 and 102. A connecting shaft 104 is connected to the rotating shaft 103 on the right fixed seat 102. The other end of the connecting shaft 104 is connected to a first transmission wheel 106. A driving member 105 is provided on the gantry frame 100. A second transmission wheel 107 is connected to the output end of the driving member 105. The system also includes a first transmission belt 108 and a second transmission belt 109. Wheel 106 and the second transmission wheel 107 both abut against the surface of the first transmission belt 108. The rotating shafts 103 on the left fixed seat 101 and the right fixed seat 102 both abut against the surface of the second transmission belt 109. It also includes a mounting seat 110 and a clamping plate 111. The mounting seat 110 and the clamping plate 111 both abut against the second transmission belt 109. The back of the mounting seat 110 and the front of the clamping plate 111 are detachably connected. There are two of each of the left fixed seat 101, the right fixed seat 102, the second transmission belt 109 and the mounting seat 110. The top of one of the mounting seats 110 is detachably connected to the base 113, and the bottom of the other mounting seat 110 is detachably connected to the machine head 112. The connecting shaft 104 passes through the rotating shafts 103 on the two right fixed seats 102. The machine head 112 and the base 113 are perpendicular to each other, and there is a gap between the machine head 112 and the base 113.

[0032] In this embodiment, the mounting base 110 and the clamping plate 111 are connected after contacting the second transmission belt 109. At this time, the mounting base 110 and the clamping plate 111 clamp the second transmission belt 109, thereby fixing the position of the mounting base 110. The machine head 112 and the base 113 are respectively mounted on different mounting bases 110, and the machine head 112 is vertically located above the base 113. There is a gap between the machine head 112 and the base 113 to ensure the fabric can pass through. The drive unit 105 is activated to make the second transmission wheel 107 rotate. Through the first transmission belt 108, the first transmission wheel 106 rotates. At the same time, the connecting shaft 104 rotates, and the rotating shafts 103 on the two right-side fixed seats 102 also rotate. This causes the two second transmission belts 109 to move synchronously, and the machine head 112 and the base 113 to move synchronously. This ensures the consistency of the stitches and the uniformity of the sewing effect, thereby ensuring product quality and reducing economic and resource waste.

[0033] Please see Figure 1 , Figure 2 , Figure 3, Figure 4 and Figure 5 In some embodiments, the second direction transmission assembly includes a transmission module 114, which is detachably connected to the front of the gantry frame 100. A feeding block 115 is provided on the top of the transmission module 114. One of the left fixed seat 101, the right fixed seat 102, the second transmission belt 109 and the mounting seat 110 are located above the transmission module 114, and the other of the left fixed seat 101, the right fixed seat 102, the second transmission belt 109 and the mounting seat 110 are located below the transmission module 114.

[0034] In this embodiment, the sewing material can be placed on the feeding block 115, and the feeding function can be realized through the transmission module 114. The transmission module 114 can use a screw, transmission belt, gear or other structure to realize the displacement of the feeding block 115.

[0035] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the gantry frame 100 is provided with a slide rail 116, and a slider 117 is slidably connected to the slide rail 116. The front of the slider 117 is detachably connected to the back of the mounting base 110.

[0036] In this embodiment, the slider 117 moves only on the slide rail 116. By limiting the slider 117, the displacement of the mounting base 110 is stabilized, thereby ensuring that the head 112 and the base 113 do not shift position during the displacement process.

[0037] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the number of clamping plates 111 is an integer multiple of the number of mounting bases 110, the number of slide rails 116 and sliders 117 are both integer multiples of the number of mounting bases 110, and the machine head 112 and base 113 are detachably connected to the mounting bases 110 by bolts or screws.

[0038] In this embodiment, the number of clamping plates 111, slide rails 116 and sliders 117 are all integer multiples of the number of mounting bases 110, and the specific number is adjusted according to the actual situation; the machine head 112 and base 113 are connected to the mounting base 110 by the above-mentioned structures, and the detachable connection structure mentioned in this application can be bolts or screws, including but not limited to the above-mentioned structures.

[0039] Specifically, the working principle of the transmission structure for a gantry sewing machine provided in this application is as follows:

[0040] After the mounting base 110 and the clamping plate 111 come into contact with the second transmission belt 109, they are connected. At this time, the mounting base 110 and the clamping plate 111 will clamp the second transmission belt 109, thereby fixing the position of the mounting base 110. The machine head 112 and the base 113 are respectively mounted on different mounting bases 110, and the machine head 112 is vertically located above the base 113. There is a gap between the machine head 112 and the base 113 to ensure the passage of the fabric.

[0041] The start-up drive unit 105 causes the second transmission wheel 107 to rotate, which in turn causes the first transmission wheel 106 to rotate via the first transmission belt 108. This causes the connecting shaft 104 to rotate, and simultaneously causes the rotating shafts 103 on both right-side fixed seats 102 to rotate. This causes the two second transmission belts 109 to move synchronously, which in turn causes the machine head 112 and the base 113 to move synchronously. The sewing material is placed on the feeding block 115, and the feeding function is realized through the transmission module 114. The material is fed into the gap between the machine head 112 and the base 113, and the machine head 112 and the base 113 sew the sewing material.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
