Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of sewing machines, and in particular relates to a column-type integrated feeding sewing machine. Background Technology
[0002] The column-type integrated feeding sewing machine is the main sewing equipment for tubular fabrics such as bags and car seat headrests. Due to the limited lifting height of the presser foot and needle, it is difficult to fit tubular fabrics into the column shuttle table. Therefore, it is necessary to purchase other models to complete the subsequent processes, which leads to an expansion of the production space, an increase in equipment costs, and a decrease in overall operating efficiency.
[0003] Currently, most column-type integrated feeding sewing machines on the market adopt a tilting column shuttle design. This design uses a purely mechanical structure to achieve synchronous tilting of the column shuttle and the lower shaft driving the rotary hook, allowing for manual placement and removal of tubular fabric. However, because the lower shaft is always connected to the main shaft via a transmission mechanism, the column shuttle can only tilt with the lower shaft as its rotation center line. Limited by the connection between the lower shaft and other components, the mechanical structure driving the tilting of the column shuttle must rely on purely manual operation, resulting in a complex structure and difficult adjustments. Furthermore, the column shuttle must be repeatedly tilted and reset manually before and after each sewing session, which is not only inefficient but also increases the operator's workload and restricts production efficiency. Utility Model Content
[0004] In view of this, it is necessary to provide a column-type integrated feeding sewing machine to solve the above-mentioned technical problems.
[0005] A column-type integrated feeding sewing machine, comprising:
[0006] Base plate;
[0007] A column shuttle table is rotatably mounted on the base plate, and the column shuttle table includes a rotary shuttle;
[0008] The lower shaft is connected to the rotary shuttle drive and is used to drive the rotary shuttle to rotate;
[0009] A coupling includes a driving component and a driven component, wherein the driven component is disposed independently of the driving component and is connected to the lower shaft;
[0010] A rotary drive is mounted on the base plate and is connected to the column shuttle table for transmission. The rotary drive can drive the column shuttle table to swing relative to the base plate, so that the driven component and the driving component are coupled / decoupled.
[0011] Understandably, by using a decoupling mechanism between the active and driven components, the lower shaft can automatically follow the swing of the column shuttle table, thereby achieving automated control of the column shuttle table's swing. This not only simplifies the structure required for the column shuttle table's swing design and facilitates system debugging, but also ensures the accuracy of the swing angle when the column shuttle table swings, thus effectively improving production efficiency and reducing the labor intensity of operators.
[0012] In one embodiment, one of the active component and the driven component protrudes to form an arcuate convex plate, and the other is recessed to form an arcuate groove;
[0013] In the swing direction of the column shuttle table, the arc-shaped protrusion can be inserted and engaged with the arc-shaped groove, thereby coupling the active component with the driven component.
[0014] It is understandable that using the interlocking of arc-shaped convex plates and arc-shaped grooves to achieve coupling between the active and driven components has the advantages of compact structure and smooth transmission. In this process, the arc-shaped contact surface between the arc-shaped convex plate and the arc-shaped groove can uniformly transmit torque, reduce impact and wear, and at the same time ensure reliable alignment during the rotation of the active component and driven component, avoiding deviation or jamming.
[0015] In one embodiment, an eccentric cam is mounted on the rotating shaft of the rotary drive;
[0016] A drive toothed fork is installed on the column shuttle table. The drive toothed fork is fitted onto the eccentric cam and abuts against the eccentric cam for limitation, thereby realizing the transmission connection between the rotary drive component and the column shuttle table.
[0017] In one embodiment, in the axial direction of the shaft portion, the eccentric cam portion extends out of the drive tooth fork and forms an extended protrusion;
[0018] The extended protrusion is connected to the rotating shaft by a fastener, and the fastener abuts against and limits the drive tooth fork in the axial direction of the rotating shaft.
[0019] It is understandable that while fixing the eccentric cam to the rotating shaft, the fixing component can also limit the assembly position of the drive tooth fork on the eccentric cam. This simplifies the structure, reduces the use of additional positioning parts, and lowers the assembly complexity. On the other hand, it can also improve the transmission accuracy and reliability between the eccentric cam and the drive tooth fork, and prevent loosening or deviation during the movement.
[0020] In one embodiment, the eccentric cam is positioned above the lower shaft in the height direction of the column shuttle table.
[0021] Understandably, setting the rotation center line of the column shuttle table above the lower shaft allows the column shuttle table to achieve a larger swing angle, thus providing operators with more operating space to fit the tubular sewing material into the column shuttle table, which facilitates operation.
[0022] In one embodiment, the drive fork includes a fork body and a support arm, the support arm extending along the axial direction of the pivot and being integrally connected to the fork body;
[0023] The toothed fork body is fitted onto the eccentric cam and abuts against and limits the eccentric cam, and the support arm is connected to the column shuttle table by a thread.
[0024] Understandably, the above structural design enhances the rigidity of the drive fork, preventing deformation during transmission and ensuring accurate and reliable power transmission from the eccentric cam, while reducing motion backlash. Furthermore, it facilitates the assembly of the drive fork on the column shuttle and creates conditions for subsequent adjustments to its position on the column shuttle.
[0025] In one embodiment, the rotary drive is configured as a stepper motor.
[0026] In one embodiment, the column-type integrated feeding sewing machine further includes a control device, which is electrically connected to the rotary drive and is used to send a first control signal and a second control signal to the rotary drive.
[0027] When the rotary drive receives the first control signal, the rotary drive causes the column shuttle table to switch from the starting position to the target position;
[0028] When the rotary drive receives the second control signal, the rotary drive causes the column shuttle table to reset from the target position to the starting position.
[0029] In one embodiment, the column-type integrated feeding sewing machine further includes a presser foot assembly and a needle;
[0030] Before the controller is triggered and sends the first control signal to the rotary drive, the presser foot assembly and the needle rise and disengage from the column shuttle table, and the driving component rotates a preset angle so that the driven component can be decoupled from the driving component in the swing direction of the column shuttle table.
[0031] When the controller is triggered and sends the second control signal to the rotary drive, the presser foot assembly and the needle descend to the working position.
[0032] In one embodiment, a rotating base is connected to the column shuttle platform, and the rotating base is rotatably connected to the base plate via a rotating pin;
[0033] The rotary drive component is connected to the rotary base via a transmission connection.
[0034] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:
[0035] The column-type integrated feeding sewing machine claimed in this application achieves automated control of the column shuttle table's swing by using a decoupling mechanism between the active and driven components, enabling the lower shaft to automatically follow the swing of the column shuttle table. This structure not only simplifies the design requirements for the column shuttle table's swing and facilitates system debugging, but also ensures the accuracy of the swing angle during the swing of the column shuttle table, thereby effectively improving production efficiency and reducing the labor intensity of operators.

[0047] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0050] like Figures 1 to 7As shown, the column-type integrated feeding sewing machine 100 provided in this application includes a base plate 10, a column shuttle table 20, a lower shaft 30, a coupling 40, and a rotary drive component 50. The column shuttle table 20 is rotatably mounted on the base plate 10 and includes a rotary hook (not shown). The lower shaft 30 is drivenly connected to the rotary hook and is used to drive the rotary hook to rotate. The coupling 40 includes a driving component 41 and a driven component 42. The driven component 42 is set independently of the driving component 41 and is connected to the lower shaft 30. The rotary drive component 50 is mounted on the base plate 10 and drivenly connected to the column shuttle table 20. The rotary drive component 50 can drive the column shuttle table 20 to swing relative to the base plate 10 and couple / decouple the driven component 42 from the driving component 41. Here, the connection method between the driven component 42 and the lower shaft 30 can adopt the conventional method of the prior art, which will not be elaborated here.
[0051] As can be seen from the above, the column-type integrated feeding sewing machine 100 of this application enables the lower shaft 30 to automatically follow the swing of the column shuttle table 20 through the decoupling mechanism between the active component 41 and the driven component 42, thereby realizing the automated control of the swing of the column shuttle table 20. This not only simplifies the structure required for the swing design of the column shuttle table 20 and facilitates system debugging, but also ensures the accuracy of the swing angle when the column shuttle table 20 swings, thereby effectively improving production efficiency and reducing the labor intensity of operators.
[0052] like Figure 3 , Figure 4 As shown, in one embodiment, a rotating base 21 is connected to the column shuttle 20. The rotating base 21 is rotatably connected to the base plate 10 via a rotating pin 22, thereby realizing the rotational assembly of the column shuttle 20 on the base plate 10.
[0053] like Figure 4 As shown, in this embodiment, the rotating base 21 is mounted on the column shuttle 20, and the rotating base 21 and the column shuttle 20 are connected by a first screw 201. Here, the rotating base 21 has four oblong holes 211, and each oblong hole 211 is fixed to the column shuttle 20 by a screw threaded through it. During this process, the structural characteristics of the oblong holes 211 can be used to adjust the installation position of the rotating base 21 on the column shuttle 20, thereby facilitating the assembly of the rotating base 21 on the base plate 10.
[0054] like Figure 4As shown, in this embodiment, the number of rotating pins 22 is configured as two. The two rotating pins 22 are symmetrically arranged on two symmetrical sides of the rotating base 21. Specifically, the rotating pins 22 can be inserted from the base plate 10 and extended into the rotating base 21. The rotating pins 22 are fixed on the base plate 10 by pressing and limiting the portion of the rotating pins 22 located inside the base plate 10 with the second screw 202 screwed on the base plate 10.
[0055] like Figure 7 As shown, in one embodiment, one of the active component 41 and the driven component 42 protrudes to form an arc-shaped convex plate 411, while the other is recessed to form an arc-shaped groove 421. In the swing direction of the column shuttle table 20, the arc-shaped convex plate 411 can be inserted into the arc-shaped groove 421 to couple the active component 41 and the driven component 42. Here, the curvature of the arc-shaped convex plate 411 is equal to the curvature of the column shuttle table 20 during swing. This embodiment uses the insertion and engagement of the arc-shaped convex plate 411 and the arc-shaped groove 421 to achieve coupling between the active component 41 and the driven component 42, which has the advantages of compact structure and smooth transmission. During this process, the arc-shaped contact surface between the arc-shaped convex plate 411 and the arc-shaped groove 421 can uniformly transmit torque, reduce impact and wear, and ensure reliable alignment during the rotation of the driven component 41 and the driven component 42, avoiding offset or jamming.
[0056] like Figure 7 As shown, in this embodiment, the arc-shaped groove 421 is disposed on the active component 41, and the arc-shaped protrusion 411 is disposed on the driven component 42. It can be understood that in other embodiments, the arc-shaped protrusion can also be disposed on the active component 41, and the arc-shaped groove can be formed on the driven component 42; or, the active component 41 and the driven component 42 can also be coupled by a square connector and a square sleeve through an insertion fit, which will not be elaborated here.
[0057] like Figure 1 As shown, in this embodiment, a clutch 60 is connected to the end of the driving component 41 away from the driven component 42. Utilizing the structural characteristics of the clutch 60, the rotation or stop of the lower shaft 30 can be controlled by the clutch 60 to meet the usage requirements of the column-type integrated feeding sewing machine 100. Here, the specific structure and working principle of the clutch 60 can adopt conventional methods of existing technology, and will not be elaborated upon here.
[0058] like Figure 1 , Figure 2As shown, in one embodiment, an eccentric cam 52 is mounted on the rotating shaft 51 of the rotary drive 50; a drive fork 53 is mounted on the column shuttle table 20, and the drive fork 53 is fitted onto the eccentric cam 52 and abuts against and limits its movement, thereby realizing the transmission connection between the rotary drive 50 and the column shuttle table 20. This allows the column-type integrated feeding sewing machine 100 of this embodiment to drive the eccentric cam 52 to rotate via the rotary drive 50, and utilize its eccentric structure to drive the drive fork 53 to reciprocate, thus converting the rotational motion into the oscillation of the drive fork 53, ultimately precisely controlling the oscillation angle of the column shuttle table 20. This mechanical transmission method is compact and reliable, ensuring the accuracy of the oscillation control of the column shuttle table 20, simplifying the design of the structure required for the oscillation of the column shuttle table 20, and improving the response speed and control accuracy of the column shuttle table 20 during oscillation.
[0059] In this embodiment, the rotary drive component 50 is configured as a stepper motor, which can be mounted on the base plate 10 via a motor bracket 501. During this process, the structural characteristics of the stepper motor allow for precise control of the swing angle of the column shuttle table 20. It is understood that in other embodiments, the rotary drive component 50 can also be configured as a servo motor, servo motor, rotary cylinder, or other power components that provide rotary driving force; these will not be elaborated upon here.
[0060] like Figure 1 , Figure 4 As shown, in one embodiment, the eccentric cam 52 is positioned above the lower shaft 30 in the height direction of the column shuttle 20. This allows the column shuttle 20 to achieve a larger swing angle, thus providing the operator with more operating space to insert the tubular sewing material into the column shuttle 20, facilitating operation. Here, the maximum swing angle of the column shuttle 20 under the control of the rotary drive 50 can be 15°, 16°, 20°, etc., and can be specifically set according to the usage requirements, which will not be elaborated here.
[0061] like Figure 2 , Figure 8As shown, in one embodiment, in the axial direction of the rotating shaft portion 51, the eccentric cam 52 extends out of the drive fork 53 and forms an extended protrusion 521; the extended protrusion 521 is connected to the rotating shaft portion 51 by a fixing member 511, and the fixing member 511 abuts against and limits the drive fork 53 in the axial direction of the rotating shaft portion 51. That is to say, in this embodiment, the fixing member 511 not only fixes the eccentric cam 52 to the rotating shaft portion 51, but also limits the assembly position of the drive fork 53 on the eccentric cam 52. This simplifies the structure, reduces the use of additional positioning parts, and reduces assembly complexity; on the other hand, it also improves the transmission accuracy and reliability between the eccentric cam 52 and the drive fork 53, and avoids loosening or offset during movement. Here, the number of fixing members 511 is configured as two, specifically, the fixing members 511 can be configured as bolts, screws, etc.
[0062] like Figure 9 As shown, in one embodiment, the drive fork 53 includes a fork body 531 and a support arm 532. The support arm 532 extends along the axial direction of the rotating shaft portion 51 and is integrally connected to the fork body 531. This enhances the structural rigidity of the drive fork 53, prevents deformation of the drive fork 53 during transmission, ensures accurate and reliable power transmission from the eccentric cam 52, and reduces motion backlash. Here, the fork body 531 is fitted onto the eccentric cam 52 and abuts against and limits its movement. Specifically, the fork body 531 can be fitted onto the main body portion 522 of the eccentric cam 52.
[0063] like Figure 9 As shown, in this embodiment, the support arm 532 is connected to the column shuttle table 20 by a thread. Specifically, the support arm 532 can be fixed to the rotating base 21 with bolts (not shown), which facilitates the assembly of the drive fork 53 on the column shuttle table 20. Here, the support arm 532 has mounting holes 5321. Two bolts pass through the corresponding mounting holes 5321 and are screwed into the rotating base 21 to achieve the assembly and fixation of the support arm 532 on the rotating base 21. This facilitates the assembly between the drive fork body 531 on the drive fork 53 and the main body 522 on the eccentric cam 52, and ensures the stability of the drive fork 53 assembled on the rotating base 21. It is understood that in other embodiments, screws, threaded rods, or other connecting parts can also be used to fix the support arm 532 to the rotating base 21.
[0064] like Figure 5 , Figure 6As shown, in one embodiment, the column-type integrated feeding sewing machine 100 further includes a control device (not shown). The control device is electrically connected to the rotary drive 50 and is used to send a first control signal and a second control signal to the rotary drive 50. When the rotary drive 50 receives the first control signal, it drives the column shuttle 20 to switch from the starting position to the target position. When the rotary drive 50 receives the second control signal, it drives the column shuttle 20 to reset from the target position to the starting position. In other words, the operator can control the swing of the column shuttle 20 by triggering the control device twice. Here, a button can be set on the column-type integrated feeding sewing machine 100 to trigger the control device. It should be noted that the target position mentioned above specifically refers to the position where the column shuttle 20 can be inserted into the column shuttle 20 by the operator after swinging.
[0065] like Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, the column-type integrated feeding sewing machine 100 also includes a presser foot assembly 70 and a needle 80. Before the controller is triggered and sends a first control signal to the rotary drive 50, the presser foot assembly 70 and the needle 80 rise and disengage from the column shuttle table 20. Specifically, the needle 80 can be driven to rise by controlling the rotation angle of the main shaft (not shown) in the column-type integrated feeding sewing machine 100, and the presser foot assembly 70 can be driven to rise by the presser foot cylinder. At the same time, the driving component 41 rotates by a preset angle so that the driven component 42 can be decoupled from the driving component 41 in the swing direction of the column shuttle table 20. After the controller is triggered and sends a second control signal to the rotary drive 50, the presser foot assembly 70 and the needle 80 descend to the working position. In other words, after the controller in this embodiment is triggered, the presser foot assembly 70 and the needle 80 are first raised and disengaged from the column shuttle table 20. Specifically, the presser foot assembly 70 and the needle 80 can be raised to their highest position to avoid collision between the presser foot assembly 70 and the needle 80 and the subsequently swinging column shuttle table 20. At the same time, the active component 41 drives the driven component 42 to rotate by a preset angle so that the arc-shaped protrusion 411 between the active component 41 and the driven component 42 can disengage from the arc-shaped groove 421 when it moves in the swing direction of the column shuttle table 20, thus satisfying the decoupling requirement between the driven component 42 and the active component 41. It should be noted that in this embodiment, the position of the arc-shaped protrusion 411 can be detected and adjusted by sensors such as photoelectric switches and Hall switches, which will not be elaborated here.
[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0067] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
