Description

Technical Field

[0001] This utility model relates to the field of sewing equipment, and in particular to an arc-shaped template mechanism and a 3D pattern making machine. Background Technology

[0002] A 3D computer pattern sewing machine is a special sewing machine used to sew patterns onto the upper fabrics of shoes, slippers, and other footwear with a certain curvature.

[0003] Chinese Patent Application No. CN201920692699.0 discloses a 3D computer-controlled pattern making machine, including a sewing machine table, a sewing machine base, and a sewing machine head. The sewing machine base and sewing machine head are both located on the sewing machine table, with the sewing machine base positioned below the sewing machine head. The machine also includes a linearly movable feeding base and a rotation drive assembly mounted on the feeding base. The rotation drive assembly has a first connecting component for connecting to a first curved template assembly. The rotation drive assembly drives the first connecting component to rotate, causing the first curved template assembly to rotate around its central axis, which is parallel to the direction of movement of the feeding base. The feeding base is located inside the sewing machine base. The first connecting component includes a rotating connecting ring connected to the rotation drive assembly and at least one clamping component mounted on the rotating connecting ring. The rotating connecting ring is coaxially connected to the first curved template assembly, and the clamping component is used to clamp the first curved template assembly and / or the fabric on the first curved template assembly. The rotation drive assembly includes a driving wheel, a driven wheel, a timing belt, and a motor. The timing belt connects the driving wheel and the driven wheel, allowing the driving wheel to rotate synchronously with the driven wheel via the timing belt. The driving wheel is connected to the motor and is driven by the motor. The rotating connecting ring of the first connecting assembly is coaxially connected to the driven wheel and is driven to rotate by the driven wheel. The motor is located below the sewing machine table, and the radius of the driven wheel is larger than the radius of the driving wheel.

[0004] In the aforementioned patent, the radii of the rotating connecting ring and the driven rotating wheel need to be matched with the curvature radius of the first arc-shaped template assembly. When using first arc-shaped template assemblies with different curvature radii for sewing, the first connecting assembly and the rotating drive assembly also need to be replaced accordingly, resulting in high modification costs. Furthermore, the rotating connecting ring and the driven rotating wheel occupy a large amount of space. If the curvature radius of the first arc-shaped template assembly is large and relatively gentle, the matching radius of the rotating connecting ring and the driven rotating wheel will be very large, easily causing structural interference to other nearby mechanisms, which is detrimental to the space design and utilization of the 3D sewing machine. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides an arc-shaped template mechanism, which has the advantages of low modification cost, compact structure and small space occupation.

[0006] This utility model also provides a 3D stereoscopic pattern machine, including the above-mentioned arc-shaped template mechanism.

[0007] The technical problem to be solved by this utility model is achieved through the following technical solution:

[0008] An arc-shaped template mechanism includes a feeding base, a first translation drive assembly, an arc-shaped rack, a linear rack, and a template connecting assembly. The arc-shaped rack is rotatably mounted on the feeding base, and the template connecting assembly is mounted on the arc-shaped rack. The first translation drive assembly is mounted on the feeding base and drives the linear rack to translate relative to the arc-shaped rack along a first direction. The linear rack has a first transmission tooth along the first direction, and the arc-shaped rack has a second transmission tooth along the first direction. The first transmission tooth and the second transmission tooth mesh with each other so that when the linear rack translates along the first direction, the arc-shaped rack drives the template connecting assembly to rotate.

[0009] Furthermore, the arc-shaped rack and the linear rack are arranged vertically opposite each other.

[0010] Furthermore, the first translation drive assembly includes a first rotating shaft, a first driving wheel, a first driven wheel, a first transmission belt, and a first translation seat. The first driving wheel is sleeved on the first rotating shaft, the first transmission belt is sleeved between the first driving wheel and the first driven wheel, and the first translation seat is fixedly mounted on the first transmission belt and located between the first driving wheel and the first driven wheel. The linear rack is connected to the first translation seat.

[0011] Furthermore, the first translation drive assembly also includes two first translation guide rails extending along the first direction. The two first translation guide rails are disposed on the feeding base and are respectively located on both sides of the first transmission belt along the second direction. The first translation base is slidably connected to the feeding base through the two first translation guide rails.

[0012] Furthermore, the arc-shaped rack is connected to the feeding base via an arc-shaped guide rail.

[0013] Furthermore, the first translation seat is provided with a first connecting arm on one side along the second direction, and the linear rack is connected to the first translation seat through the first connecting arm; the feeding base is provided with a second connecting arm on one side along the second direction, and the second connecting arm is provided with an arc-shaped guide rail, and the arc-shaped rack is connected to the feeding base through the arc-shaped guide rail on the second connecting arm.

[0014] Furthermore, the template connection assembly includes an arc-shaped support plate, an arc-shaped pressure plate, a pressure plate connecting arm, and a pressure plate driver. The arc-shaped support plate and the pressure plate driver are fixedly mounted on the arc-shaped rack, and the arc-shaped pressure plate is disposed opposite to the arc-shaped support plate. The pressure plate driver drives the arc-shaped pressure plate to move relative to the arc-shaped pressure plate through the pressure plate connecting arm.

[0015] Furthermore, the arc-shaped template mechanism also includes a second translation drive component, which drives the feeding base to translate along the second direction.

[0016] Furthermore, the second translation drive assembly includes a second rotating shaft, a second driving wheel, a second driven wheel, a second transmission belt, and a second translation seat. The second driving wheel is sleeved on the second rotating shaft, the second transmission belt is sleeved between the second driving wheel and the second driven wheel, and the second translation seat is fixedly mounted on the second transmission belt and located between the second driving wheel and the second driven wheel. The feeding base is mounted on the second translation seat.

[0017] A 3D pattern making machine includes a sewing machine table, a sewing machine base, a sewing machine head, and the aforementioned arc-shaped template mechanism. The sewing machine base, sewing machine head, and arc-shaped template mechanism are all disposed on the sewing machine table. The arc-shaped template mechanism and the sewing machine base are located below the sewing machine head. The feeding base and the first translation drive assembly are disposed inside the sewing machine base. The arc-shaped rack, the linear rack, and the template connecting assembly are disposed outside the sewing machine base.

[0018] This utility model has the following beneficial effects: The arc-shaped template mechanism of this utility model adopts a transmission structure in which the arc-shaped rack and linear rack cooperate, converting the translational driving force output by the first translational driving component into a rotational driving force to drive the template connecting component to rotate; the length of the linear rack only needs to match the arc length of the arc-shaped rack, and is independent of the radius of curvature of the arc-shaped rack. When using arc-shaped templates with different radii of curvature for sewing, only the template connecting component and the arc-shaped rack need to be replaced, without replacing the first translational driving component and the linear rack. As long as the arc length of the arc-shaped rack is less than or equal to the length of the arc-shaped rack, the modification cost is low; in addition, the arc-shaped rack and linear rack occupy less space, which makes the structure more compact. Even if the radius of curvature of the arc-shaped template is large and gentle, the space occupied by the arc-shaped rack changes very little, and it is not easy to cause structural interference to other nearby mechanisms.

The arc-shaped rack 43 is rotatably mounted on the feeding base 41, and the template connecting assembly 45 is mounted on the arc-shaped rack 43. The first translation drive assembly 42 is mounted on the feeding base 41 and drives the linear rack 44 to translate relative to the arc-shaped rack 43 along a first direction X. The linear rack 44 has a first transmission tooth 441 along the first direction X, and the arc-shaped rack 43 has a second transmission tooth 431 along the first direction X. The first transmission tooth 441 and the second transmission tooth 431 mesh with each other so that when the linear rack 44 translates along the first direction X, the arc-shaped rack 43 drives the template connecting assembly 45 to rotate.

[0028] The arc-shaped template mechanism of this utility model adopts a transmission structure in which the arc-shaped rack 43 and the linear rack 44 cooperate to convert the translational driving force output by the first translational driving component 42 into a rotational driving force to drive the template connecting component 45 to rotate. The length of the linear rack 44 only needs to match the arc length of the arc-shaped rack 43, and is independent of the radius of curvature of the arc-shaped rack 43. When using arc-shaped templates with different radii of curvature for sewing, only the template connecting component 45 and the arc-shaped rack 43 need to be replaced, without replacing the first translational driving component 42 and the linear rack 44. As long as the arc length of the arc-shaped rack 43 is less than or equal to the length of the arc-shaped rack 43, the modification cost is low. In addition, the arc-shaped rack 43 and the linear rack 44 occupy less space, which can make the structure more compact.

The arc-shaped pressure plate 452 is disposed opposite to the arc-shaped support plate 451. The pressure plate driver 454 drives the arc-shaped pressure plate 452 to move relative to the arc-shaped pressure plate 452 through the pressure plate connecting arm 453.

[0037] Preferred, such as Figure 2 As shown, the arc-shaped template mechanism further includes a second translation drive component 48, which drives the feeding base 41 to translate along the second direction Y.

[0038] The second translation drive assembly 48 includes a second rotating shaft 481, a second driving wheel 482, a second driven wheel 483, a second transmission belt 484, and a second translation seat 485.
