Description

Technical Field

[0001] This application relates to the field of sewing equipment technology, and in particular to a backrest adjustment mechanism for a bag-applying machine and the bag-applying machine itself. Background Technology

[0002] The patching machine is mainly used to attach and sew bag-shaped fabric to jeans, shirts, etc. Its basic principle is to place a piece of bag-shaped fabric on a patch plate (also called a flap), and use cooperating die-cutting tools and folding blades to fold the sides, front, and two corners of the fabric. During the folding process, the patch plate falls to fix the folded fabric to the worktable. Then, the folding blade retracts and leaves the work area, the receiving plate moves above the patch plate and presses down on the folded bag, and the patch plate retracts, completing the folding process.

[0003] To hold and fix the bag-shaped fabric, a concave mold is set up as a limiting component. When the thickness of the bag-shaped fabric changes, compensation is usually made by adding a shim to the bottom side of the concave mold. When the thickness change is large, the entire concave mold needs to be replaced. Not only is the operation cumbersome, but the shim also has the risk of curling up or even falling off, and it has poor adaptability to changes in fabric thickness. Utility Model Content

[0049] In order to improve the adaptability of the bag-applying machine, especially the backrest 700 of the bag-applying machine, to changes in fabric thickness and to achieve automated adjustment of the backrest 700, this application discloses a backrest adjustment mechanism for the bag-applying machine.

[0050] Reference Appendix Figure 1 To be continued Figure 4 The illustrated embodiment discloses a backrest adjustment mechanism for a bag-applying machine, specifically including a base plate 100 and a backrest 700 movably disposed on the base plate 100. The base plate 100 has opposing top and bottom sides. A right-angle motor 710 is mounted on the top side of the base plate 100, and the right-angle motor 710 has an input shaft 711 and an output shaft 712 extending perpendicularly to each other, with the output shaft 712 pointing towards the bottom side of the base plate 100. The backrest 700 is vertically detachable on the bottom side of the base plate 100 and connected to the output shaft 712, and its movement relative to the base plate 100 is achieved by driving the output shaft 712. The movement guidance of the backrest 700 can be achieved through the output shaft 712 itself or through a guide mechanism 720. The guide mechanism 720 acts between the backrest 700 and the base plate 100, guiding the backrest 700 to move up and down.

[0051] The right-angle motor 710 enables the adjustment of the backrest 700, allowing for active adjustment of the backrest 700 within a compact space. This, combined with other components, enables the bag-applying machine to achieve automated control and adjustment for fabrics of different thicknesses, improving adaptability and production efficiency.

[0052] Regarding the details of the adjustment structure for the backrest 700, the movement of the backrest 700 can be directly driven by the output shaft 712. For example, the output shaft 712 can move axially relative to the substrate 100 to drive the backrest 700 to move relative to the substrate 100. See also the attached diagram. Figure 4 In this configuration, the output shaft 712 engages with the backing plate 700 via a screw connector 713. During rotation, the output shaft 712 allows the backing plate 700 to move axially relative to the base plate 100. The backing plate 700 is hollow in the middle to allow the output shaft 712 to extend. A mounting plate 701 is provided on the top surface of the backing plate 700, and the screw connector 713 is mounted on the mounting plate 701.

[0053] Reference Appendix Figure 2 and attached Figure 4In the illustrated embodiment, the guiding mechanism 720 includes a cooperating guide hole and a guide post 722. The guide hole is formed in the substrate 100, and a guide sleeve 721 is provided at the guide hole. The bottom of the guide post 722 is fixed to the backrest 700, and its top extends to the top side of the substrate 100 via the guide sleeve 721. The bottom of the guide post 722 can be directly fixed to the backrest 700 or fixed to the mounting plate 701 mentioned above. The connection position between the guide post 722 and the backrest 700 is eccentrically positioned relative to the output shaft 712 to provide stable guidance to the backrest 700. The guide sleeve 721 and the guide hole provide a movement channel penetrating the substrate 100, within which the guide post 722 penetrates both sides of the substrate 100. (See attached diagram.) Figure 4 It is known that the movement path of the guide post 722 is parallel to its own axis and is also parallel to the axis of the output shaft 712. Furthermore, the guide hole and the input shaft 711 are located on opposite radial sides of the output shaft 712, meaning the right-angle motor 710 and the guide post 722 are respectively located on opposite radial sides of the output shaft 712. This arrangement avoids interference between the arrangement of the right-angle motor 710 and the movement path of the guide post 722, achieving a compact layout. The adjustment process of the backrest 700 can be closed-loop controlled, i.e., precise adjustment is achieved by reading the relative position of the backrest 700 through sensors. For example, the backrest adjustment mechanism also includes a detector 730 for detecting the height of the backrest 700 and / or the guide post 722, generating a corresponding detection signal. The detector 730 can be an angle sensor; for example, the angle sensor can be placed inside the right-angle motor 710 to detect the rotation angle of the right-angle motor 710, or it can be set for the output shaft 712. See also the appendix. Figure 1 In this circuit, detector 730 is positioned for guide post 722. Detector 730 is fixed to the top side of substrate 100 and detects the top position of guide post 722. Detector 730 can be a displacement sensor that continuously detects the height of guide post 722, or a proximity switch triggered by the extreme position of guide post 722. When guide post 722 reaches a predetermined position, detector 730 generates a corresponding detection signal.

[0054] Within a compact space, the backrest adjustment mechanism of the bag-applying machine can achieve precise drive and control of the backrest 700 through components located on both sides of the base plate 100, providing a structural basis for the overall layout of the bag-applying machine while realizing the backrest 700 adjustment function.

[0055] During the adjustment of the backrest 700, the right-angle motor 710 rotates the output shaft 712, and the backrest 700 moves closer to or further away from the base plate 100 in the axial direction of the output shaft 712 to achieve position adjustment of the backrest 700. During the movement of the backrest 700, the detector 730 is used to detect the position signal of the guide post 722 to accurately control the movement process of the backrest 700.

[0056] Reference Appendix Figure 5 To be continued Figure 7 In the illustrated embodiment, this application also discloses a bag-applying machine, comprising:

[0057] The backing adjustment mechanism can be the same as the backing adjustment mechanism of the bag-applying machine in the above embodiments;

[0058] The bag-shaped plate (not shown in the figure) and the backing plate 700 use magnetic force to hold the bag-shaped fabric. The magnetic force can be provided by the backing plate. For example, the backing plate 700 is an integral magnetic unit. The magnetic unit is a permanent magnet or an electromagnet. The magnetic unit is disc-shaped as a whole.

[0059] Unit mold 200, multiple unit molds 200 are provided and arranged around the backing 700, and the unit mold 200 cooperates with the bag-shaped plate to define the edge of the bag-shaped fabric;

[0060] Folding knife component 300, folds the edge of bag-shaped fabric.

[0061] The support 700 is located within the space enclosed by all unit modules 200, and its height can be adjusted relative to the plane where the unit modules 200 are located. (See attached reference.) Figure 6 In this design, the unit module 200 is adjustable in position relative to the substrate 100. Each unit module 200 is arranged around the backrest 700. The top side of the substrate 100 is provided with a lead screw mechanism 400 that is linked to each unit module; the lead screw mechanism 400 is mounted above the right-angle motor 710. (See attached diagram) Figure 7 In the configuration, the lead screw mechanism 400 is sequentially connected to the lead screw motor 410, the coupling 420, and the drive lead screw 430. Multiple folding knife assemblies 300 are included and linked to the lead screw mechanism 400 for position adjustment. Each folding knife assembly 300 includes a folding knife cylinder and a folding knife driven by the cylinder. The folding knife cylinder is located on the top or bottom side of the base plate 100. The piston rod of the folding knife cylinder is connected to a coupling seat, and a locking cylinder is provided on the coupling seat. The folding knife is detachably inserted and fixed to the locking cylinder. To optimize the allocation of space on the top side of the base, the extension direction of the drive lead screw 430 is perpendicular to the extension direction of the input shaft 711 of the right-angle motor 710 and parallel to the top surface of the base plate 100. The right-angle motor 710 is arranged directly below the coupling 420.

[0062] The specific adjustment process of the Kaoshan 700 can be described in detail above. Other parts of the bag-applying machine can be implemented using existing technologies, and will not be elaborated here.

[0063] Overall, the components of the backrest adjustment mechanism are stacked on the top and bottom sides of the base plate 100 to optimize the layout of the components on the base plate 100. On the top side of the base plate 100, the right-angle motor 710 avoids the lead screw mechanism 400; on the bottom side of the base plate 100, the backrest 700 is located within the space enclosed by the unit mold 200, which can fully release the movement stroke of the unit mold 200 and the folding knife assembly 300, providing sufficient adjustment space for the bag-applying machine to meet the processing requirements of different sizes, while ensuring a compact overall structure.

[0064] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application.
