Description

Technical Field

[0001] This application relates to the field of sewing machine technology, and more particularly to a template positioning and moving mechanism for a sewing machine. Background Technology

[0002] A sewing machine is a device that stitches patterns onto fabric. It works by repeatedly threading a needle through the fabric to create specific designs. Previously, most sewing machines were operated manually, which was time-consuming and prone to errors. With rising living standards, patterned fabrics have become increasingly popular. However, traditional sewing methods are inefficient. Therefore, factories mostly use automatic sewing machines, where operators simply place the product into a template for automatic sewing.

[0003] Currently, most automatic sewing machines can only automate the sewing process; the fabric feeding and positioning still require manual operation. This undoubtedly adds significant labor costs to the product. Furthermore, manual feeding and positioning are inherently more prone to instability, and operational errors can increase the defect rate. Therefore, to further improve processing efficiency and yield, a device capable of positioning and moving the sewing machine template is urgently needed. Utility Model Content

[0004] One objective of this application is to provide a template positioning and moving mechanism for a sewing machine that can solve at least one of the defects in the aforementioned background art.

[0005] To achieve at least one of the above objectives, the technical solution adopted in this application is as follows: a template positioning and moving mechanism for a sewing machine, comprising a machine body and a platform mounted on top of the machine body, wherein a template is placed on the platform, and moving components are installed on both sides of the machine body, wherein the moving components include a conveyor belt and a first cylinder, the first cylinder being fixedly mounted on the conveyor belt; a mutually cooperating locking structure is provided between the telescopic section of the cylinder and the template, and the first cylinders on both sides adopt a delayed working mode, wherein the first cylinder on one side first positions and engages with the template, and then the first cylinder on the other side clamps and engages with the template.

[0006] With the above settings, when the template is placed at the designated point, the first cylinders on both sides of the machine body start and engage with the template. Then, the template is moved synchronously by the rotation of the conveyor belt. The first cylinders on both sides operate with a delay. The first cylinder on one side engages in one step to position and cooperate, which can effectively limit the position of the template and prevent the template from shaking and affecting the positioning accuracy. Then, the first cylinder on the other side clamps and cooperates to ensure the clamping and positioning purposes.

[0007] Preferably, the telescopic section of the first cylinder is provided with a locking block, and both sides of the template are provided with a first locking groove and a second locking groove. The locking block is used to cooperate with the first locking groove or the second locking groove to form the locking structure. With this configuration, when it is necessary to move the template, the locking block can be controlled by the first cylinder to extend into the first locking groove or the second locking groove to ensure that the first cylinder can drive the template to move synchronously; wherein the first locking groove and the second locking groove are spaced apart to increase the movement range of the template.

[0008] Preferably, the assembly also includes at least one clamping plate assembly, which comprises an upper clamping plate and a lower clamping plate. A connecting plate is mounted on the bottom of the first cylinder, and the connecting plate is fixedly connected to the upper clamping plate. The lower clamping plate is used to cooperate with the upper clamping plate to clamp the conveyor belt. This configuration allows the first cylinder to be fixedly mounted on the conveyor belt through the clamping cooperation of the upper and lower clamping plates, ensuring that the first cylinder can rotate synchronously with the conveyor belt.

[0009] Preferably, the upper clamping plate and the lower clamping plate are fixed together by fasteners, and the mating surfaces of the upper clamping plate and / or the lower clamping plate are provided with an anti-slip structure. This configuration can further improve the clamping effect of the upper and lower clamping plates on the conveyor belt, and prevent slippage between the clamping plate assembly and the conveyor belt, which would cause the position of the first cylinder on the conveyor belt to change.

[0010] Preferably, the connecting plate is provided with a slide rail, and the first cylinder is provided with a slide groove that cooperates with the slide rail. The first cylinder is slidably mounted on the slide rail, and the sliding direction is towards / away from the platform. A limiting structure for fixing the first cylinder is provided between the slide rail and the slide groove. With this configuration, when the size of the template changes, the movement range of the locking block can be adjusted by changing the position of the first cylinder on the slide rail.

[0011] Preferably, a cooperating positioning structure is provided between the body and the template, the positioning structure being used to define the initial position of the template on the platform. With this configuration, when the template is placed on the platform, the positioning structure can quickly adjust the template to the correct position.

[0012] Preferably, the positioning structure includes a positioning hole and a positioning rod. A second cylinder is mounted on the machine body, the positioning rod is located in the telescopic section of the second cylinder, and the positioning groove is located in the template. The cylinder is used to drive the positioning rod to extend into / remove from the positioning hole. With this configuration, when the template is placed on the platform, the second cylinder controls the positioning rod to extend into the positioning hole to ensure the template is in the correct position, preventing template tilting and resulting in pattern sewing deviation. When the template moves, the second cylinder drives the positioning rod to disengage from the positioning hole, thereby releasing the limiting effect on the template.

[0013] Preferably, a drive assembly is installed on the machine body to drive the conveyor belt to rotate. With this configuration, when the template needs to move, the drive assembly can drive the conveyor belt to rotate, which in turn drives the first cylinder to move synchronously with the template.

[0014] Preferably, the drive assembly includes a motor and a shaft. The motor is installed inside the machine body and drives the shaft to rotate. The shaft is provided with a connector that mates with the conveyor belt. With this configuration, the motor drives the shaft to rotate left and right. When the shaft rotates, the connector provides power to the conveyor belt and drives it to rotate.

[0015] Preferably, the connecting member is a gear, and the outer contour of the gear contacts the inner side of the conveyor belt. With this configuration, when the gear rotates, the friction effect can drive the conveyor belt to rotate synchronously.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: The first cylinders are arranged on both sides of the machine body. After the template is sewn and positioned in the initial position, the first cylinders on both sides cooperate to clamp and feed the material. The first cylinders on both sides adopt a delayed clamping method. The first cylinder on one side first cooperates with the template for a certain period of time to position and limit the position of the template to prevent the template from shaking and affecting the positioning accuracy. Then the first cylinder on the other side clamps and cooperates, which can achieve the purpose of clamping and positioning.

[0017] Both sides of the template are provided with a first slot and a second slot, which are spaced apart to effectively increase the movable range of the template. When the template is placed on the platform, the second cylinder controls the positioning rod to extend into the positioning hole to ensure that the template is in the correct position and to prevent the pattern from shifting due to template tilt. This utility model has the advantages of high positioning accuracy, long moving stroke and strong adjustability. Attached Figure Description

[0025] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0027] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0028] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0029] One aspect of this application provides a template positioning and moving mechanism for a sewing machine, wherein a preferred embodiment is, for example... Figure 1 and Figure 2As shown, the machine includes a body 1 and a platform 11 mounted on top of the body 1. A template 100 is placed on the platform 11, and products to be processed can be placed on the template 100. Moving components 2 for moving the template 100 are installed on both sides of the body 1. The moving components 2 include a conveyor belt 21 and a first cylinder 22. The first cylinder 22 is fixedly mounted on the conveyor belt 21, and a locking structure is provided between the telescopic section of the cylinder and the template 100. The cylinder is integrally connected to the template 100 through the locking structure, and the rotation of the conveyor belt synchronously drives the template 100 to move.

[0030] Furthermore, the first cylinders 22 on both sides adopt a delayed operation mode. One side's first cylinder 22 engages with the template 100 in a positioning manner first, and then the other side's first cylinder 22 engages with the template 100 in a positioning manner. By engaging with the template 100 in a positioning manner on one side first, the position of the template 100 can be effectively restricted, preventing the template 100 from shaking and affecting the positioning accuracy. Then, the first cylinder 22 on the other side engages with the clamping manner, which can achieve the purpose of clamping and positioning.

[0031] Specifically, such as Figure 3 and Figure 4 As shown, the telescopic section of the first cylinder 22 is equipped with a locking block 220. Both sides of the template 100 are provided with a first locking groove 101 and a second locking groove 102. The locking block 220 is used to engage with the first locking groove 101 or the second locking groove 102 to form a locking structure. When it is necessary to move the template 100, the locking block 220 can be controlled by the first cylinder 22 to extend into the first locking groove 101 or the second locking groove 102, thereby temporarily integrating the first cylinder 22 and the template 100 into a single structure, thus ensuring that the first cylinder 22 can drive the template 100 to move synchronously.

[0032] Additionally, the first card slot 101 and the second card slot 102 should be spaced apart to increase the movement range of the template 100. The specific spacing can be adjusted by those skilled in the art according to actual needs. Alternatively, the number of card slots can be appropriately increased; for example, a third and fourth card slot can be provided between the first card slot 101 and the second card slot 102.

[0033] In this embodiment, as Figure 2 and Figure 5 As shown, in order to ensure that the first cylinder 22 can move synchronously under the rotation of the conveyor belt 21, this application also includes a clamping plate assembly 3. The clamping plate assembly 3 includes an upper clamping plate 31 and a lower clamping plate 32. A connecting plate 200 is installed at the bottom of the first cylinder 22. The connecting plate 200 is fixedly connected to the upper clamping plate 31, while the lower clamping plate 32 is used to cooperate with the upper clamping plate 31 to clamp the conveyor belt 21, so that the first cylinder 22 can rotate synchronously with the conveyor belt 21.

[0034] It is understandable that there can be multiple clamping plate assemblies 3. When it is necessary to improve the stability of the first cylinder 22, multiple clamping plate assemblies 3 can be set to enhance the clamping effect.

[0035] Furthermore, such as Figure 5 As shown, the upper clamping plate 31 and the lower clamping plate 32 are fixed together by fasteners. When it is necessary to disassemble the clamping plate assembly 3, the fasteners can be unscrewed to complete the disassembly. In addition, the mating surfaces of the upper clamping plate 31 and / or the lower clamping plate 32 are provided with anti-slip structures; this further improves the clamping effect of the upper clamping plate 31 and the lower clamping plate 32 on the conveyor belt 21, and prevents slippage between the clamping plate assembly 3 and the conveyor belt 21, which would cause the position of the first cylinder 22 on the conveyor belt 21 to change. Specific anti-slip structures include, but are not limited to, anti-slip teeth, rubber pads, and other structures that can increase friction.

[0036] It is understandable that in practical applications, the size of the template 100 may not be the same. When the size of the template 100 changes, the depth of the first groove and the second groove may also change. Therefore, if the clamping block 220 cannot clamp and engage with the first groove or the second groove, the template 100 may shift, thereby affecting the processing quality of the product.

[0037] Therefore, in order to address the above problems, in some embodiments of this application, such as Figure 2 As shown, a slide rail 201 is provided on the connecting plate 200, and the first cylinder 22 is slidably mounted on the slide rail 201, with the sliding direction being towards / away from the platform 11; a limiting structure for fixing the first cylinder 22 is provided between the slide rail 201 and the slide groove 221. When the size of the template 100 changes, the movement range of the clamping block 220 can be adjusted by changing the position of the first cylinder 22 on the slide rail 201 to ensure that the clamping block 220 can clamp into the first groove or the second groove. Of course, the clamping degree of the clamping block 220 on the template 100 can also be adjusted by the slide rail 201.

[0038] In this embodiment, a positioning structure is provided between the body 1 and the template 100 to define the initial position of the template 100 on the platform 11. When the template 100 is placed on the platform 11, the positioning structure finds the mating point between the body 1 and the template 100. Once the positioning structure has completed the mating, it is the correct placement point of the template 100, thereby further improving the positioning speed of the template 100.

[0039] Specifically, such as Figure 4 and Figure 6As shown, the positioning structure includes a positioning hole 103 and a positioning rod 41, and a second cylinder 4 is installed on the machine body 1. The positioning rod 41 is located in the telescopic section of the second cylinder 4, and the positioning groove is located on the template 100. The cylinder is used to drive the positioning rod 41 to extend into / remove from the positioning hole 103. When the template 100 is placed on the table 11, the second cylinder 4 controls the positioning rod 41 to extend into the positioning hole 103 to ensure that the template 100 is in the correct placement position and to avoid the template 100 tilting and causing the pattern sewing to shift. When the template 100 moves, the second cylinder 4 drives the positioning rod 41 to disengage from the positioning hole 103 to release the limiting effect on the template 100.

[0040] In this embodiment, a drive assembly is installed on the machine body 1. The drive assembly is used to drive the conveyor belt 21 to rotate. When the template 100 needs to move, the drive assembly can drive the conveyor belt 21 to rotate, and the conveyor belt 21 will drive the first cylinder 22 to move synchronously with the template 100.

[0041] Specifically, such as Figure 6 As shown, the drive assembly includes a motor 300 and a shaft 301. The motor 300 is installed inside the machine body 1 and is used to drive the shaft 301 to rotate. The shaft 301 is provided with a connector that cooperates with the conveyor belt 21. The motor 300 can drive the shaft 301 to rotate left and right. When the shaft 301 rotates, the connector can provide power to the conveyor belt 21 and drive the conveyor belt 21 to rotate.

[0042] Furthermore, such as Figure 5 As shown, the connecting component is a gear 302, and the outer contour of the gear 302 contacts the inner side of the conveyor belt 21. When the gear 302 rotates, it can drive the conveyor belt 21 to rotate synchronously using the friction effect. However, it is necessary to ensure that the friction between the gear 302 and the conveyor belt 21 is sufficient to drive the conveyor belt 21 to rotate without slipping. Of course, in order to further improve the fit between the gear 302 and the conveyor belt 21, an anti-slip pad can be provided on the gear 302, or a groove that mates with the gear 302 can be provided on the conveyor belt 21.

[0043] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
