Description

Technical Field

[0001] This technical solution relates to the field of button attaching machine technology, and specifically refers to a height adjustment mechanism for a button attaching machine feeding device. Background Technology

[0002] Button attaching machines, also known as riveting machines, are widely used in garment factories and leather goods processing. They are mainly used to attach various metal buttons to knitted garments, down jackets, denim clothing, shoes, hats, leather products, etc.

[0003] The button-attaching machine has two feeding devices to transport the upper and lower buttons of the buttons respectively, realizing the automation of the feeding of the upper and lower buttons. However, the existing feeding devices still have the following shortcomings: 1. The feeding device has poor applicability. Because the thickness of the raised edge of buttons varies with different specifications, the distance between the feeding device and the support plate must be adapted to the thickness of the button's raised edge. That is, the height of the feeding channel needs to be adapted to the thickness of the button to ensure that the button is smoothly pushed by the feeding device and moves normally to the set position on the support plate. Different models of feeding devices are required for buttons of different thicknesses. Therefore, it is necessary to frequently change different models of feeding devices to adjust the distance between the feeding device and the support plate, which reduces production efficiency, is not convenient to use, and requires multiple sets of feeding devices, which increases both production and storage costs.

[0004] 2. The height adjustment of the feeding device relative to the support plate requires manual replacement of the feeding device. The lack of CNC automation design means that the installation accuracy of the feeding device is affected by the error of manual operation, making it difficult to accurately match the thickness of the button ridge between the feeding device and the support plate, thus affecting the feeding stability and wasting time and effort. Utility Model Content

[0005] The purpose of this technical solution is to provide a height adjustment mechanism for the feeding device of a button attaching machine. By setting a slide block on the frame of the button attaching machine, a sliding component is slidably set on the upper end of the slide block, and a feeding device is installed at the front end of the sliding component. The drive gear rotates and cooperates with the rack to drive the sliding component to slide, thereby changing the distance between the feeding device of the sliding component and the material support plate of the button attaching machine frame. This improves the problem of poor adaptability of existing feeding devices and the time-consuming and laborious height adjustment when dealing with different buttons.

[0006] The purpose of this technical solution is achieved as follows: A height adjustment mechanism for a button-attaching machine feeding device includes: A slide block with a guide block at its upper end is used to slide on the frame of the button attaching machine; A sliding member is provided with a guide groove, which cooperates with the guide block to allow the sliding member to slide on the slide block, and the front end of the sliding member is used to install the feeding device of the button attaching machine. A gear, which is rotatably mounted on the side end of the guide block; A rack is vertically disposed on the side end of the slider, and the rack meshes with the gear; By driving the gear to rotate, the gear drives the rack to move, thereby causing the slider to slide on the slide block, thus adjusting the height of the feeding device of the button-attaching machine.

[0007] Preferably, it further includes: A locking component, which connects the slide block and the slider, is used to restrict the movement of the slider on the slide block; The locking component includes: A strip-shaped hole is formed on the guide block; A locking member has a locking portion at its rear end, the front end of the locking member passes through the strip hole and is connected to the sliding member, and the locking portion abuts against the edge of the strip hole to form the locking structure; Alternatively, the slotted hole is formed on the slider, the front end of the locking member passes through the slotted hole and is connected to the guide block, and the locking part abuts against the edge of the slotted hole to form the locking structure.

[0008] Preferably, the gear has an adjustment hole at its center, which is used for inserting a driving component to drive the gear to rotate.

[0009] Preferably, the guide groove is a dovetail groove, and the guide block is a dovetail block, used to restrict the guide block from disengaging from the guide groove.

[0010] Preferably, it further includes: A self-locking motor is mounted on the slide block. The drive end of the self-locking motor is connected to the adjustment hole of the gear. The self-locking function of the self-locking motor restricts the rotation of the gear to form the locking structure.

[0011] Preferably, the rack is integrally formed on the side end of the slider; Alternatively, the rack may have a mounting portion on its side, and a plurality of fasteners may be connected to the mounting portion, with the ends of the fasteners passing through the mounting portion and connecting to the side end of the sliding member.

[0012] Preferably, the guide block has a connecting portion formed on its side end, and the connecting portion has a rotating hole; The gear is provided with a rotating shaft, which is rotatably disposed within the rotating hole.

[0013] Preferably, a snap-fit ​​groove is provided on the end side of the rotating shaft, and a clamp is snapped into the snap-fit ​​groove. The clamp abuts against the edge of the rotating hole to prevent the rotating shaft from disengaging from the rotating hole.

[0014] The key and beneficial technical effects of this technical solution compared to existing technologies are: 1. This technical solution involves setting a slide block on the frame of the button attaching machine, with a sliding component slidably mounted on the upper end of the slide block. A feeding device is installed at the front end of the sliding component. The sliding component is driven to slide by rotating a drive gear and cooperating with a rack and pinion. This changes the distance between the feeding device mounted on the sliding component and the material support plate mounted on the frame of the button attaching machine, thereby adjusting the height of the feeding channel. This allows the machine to adapt to feeding buttons of different thicknesses. The overall adjustment is convenient, time-saving, and labor-saving.

[0015] 2. This technical solution is equipped with a self-locking motor. The drive end of the self-locking motor is connected to the adjustment hole of the gear. By driving the gear to rotate through the self-locking motor, the sliding part can be moved up and down on the upper end of the slide block. The self-locking function of the self-locking motor restricts the movement of the sliding part, thereby realizing the adjustment of the distance between the feeding device and the material support plate. At the same time, through the cooperation of the control program of the self-locking motor and the button attaching machine, the height adjustment of the feeding device can be numerically controlled and automated. This can not only adapt to the feeding needs of buttons of different thicknesses, but also improve the accuracy of the height adjustment of the feeding device and reduce the error caused by manual operation.

[0025] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1: Combination Figures 1-4 A height adjustment mechanism for a button-attaching machine feeding device includes: The slide 1 has a guide block 2 at its upper end. The slide 1 is used to slide on the frame 100 of the button attaching machine. The sliding member 3 is provided with a guide groove 4. The guide groove 4 cooperates with the guide block 2 to allow the sliding member 3 to be slidably disposed on the slide block 1, that is, the guide block 2 is slidably disposed in the guide groove 4. The front end of the sliding member 3 is used to install the feeding device 101 of the button attaching machine. The feeding device 101 in this technical solution does not include the material support plate 102. Gear 5, which is rotatably mounted on the side end of guide block 2; The rack 6 is vertically disposed on the side end of the sliding member 3, and the rack 6 meshes with the gear 5; Locking component 7, which connects slide 1 and slider 3, is used to restrict the movement of slider 3 on slide 1; A locking structure is provided between the slide block 1 and the sliding member 3 or the gear 5. The locking structure is used to restrict the sliding member 3 on the slide block 1 so that the sliding member 3 is maintained in the set position. By driving the gear 5 to rotate, the gear 5 drives the rack 6 to move up and down relative to the slide 1, thereby causing the sliding member 3 to slide on the slide 1, thus adjusting the height of the feeding device 101 of the button attaching machine, that is, adjusting the distance between the feeding device 101 and the material support plate 102, so that the distance between the feeding device 101 and the material support plate 102 can accommodate the button protrusion 202 of the button 200.

[0027] The slide block 1 is slidably mounted on the guide rail 103 of the frame 100 of the button attaching machine. The frame 100 located at the front end of the guide rail 103 is provided with a material support plate 102, which is used to support the button 200. The front end of the sliding member 3 is equipped with a feeding device 101, which is located above the material support plate 102. The feeding device 101 is used to clamp the button 200 and drive the button 200 to slide to a set position on the upper end of the material support plate 102. The distance between the feeding device 101 and the material support plate 102 is used to avoid the button protrusion 202. By adjusting the position of the sliding member 3 on the slide block 1, the distance between the feeding device 101 and the material support plate 102 can be adjusted, thereby adapting to button protrusions 202 of different thicknesses.

[0028] Combination Figure 3 and Figure 4 Locking component 7 includes: A strip hole 8 is formed on the sliding member 3, and the strip hole 8 passes through the bottom of the guide groove 4; The locking element 9 is a bolt or screw. The rear end of the locking element 9 has a locking part 18. The front end of the locking element 9 passes through the strip hole 8 and is threadedly connected to the guide block 2. The locking part 18 abuts against the edge of the strip hole 8 to restrict the sliding of the sliding member 3 on the guide block 2. The locking part 18 abuts against the edge of the strip hole 8 to form a locking structure. A gasket is provided between the locking part 18 and the strip hole 8. The gasket increases the contact surface between the locking part 18 and the strip hole 8 to ensure the stability of the relative static state of the sliding member 3 on the guide block 2.

[0029] Combination Figure 3 and Figure 4 The center of gear 5 is provided with an adjustment hole 10. The adjustment hole 10 is used for the insertion of the driving component to drive the gear 5 to rotate. In this embodiment, the adjustment hole 10 is an internal hexagonal hole. When it is necessary to drive the gear 5 to rotate, the driving component (i.e., a screwdriver) is manually inserted into the adjustment hole 10, thereby driving the gear 5 to rotate.

[0030] When adjusting the position of the slider 3 on the slide block 1, first loosen the locking piece 9, and then drive the gear 5 to rotate through the drive piece (i.e., screwdriver). The slider 3 slides on the slide block 1 through the cooperation between the gear 5 and the rack 6. Finally, tighten the locking piece 9 to lock the position of the slider 3.

[0031] Combination Figure 3 and Figure 4 The rack 6 is integrally formed on the side end of the sliding member 3, that is, the rack 6 is formed on the rear end of the sliding member 3.

[0032] Combination Figure 3 and Figure 4The guide block 2 has a connecting part 13 formed on its side end, and the connecting part 13 has a rotating hole 14; the gear 5 is provided with a rotating shaft 15, which is rotatably disposed in the rotating hole 14.

[0033] Combination Figure 3 and Figure 4 A snap-fit ​​groove 16 is provided on the end side of the rotating shaft 15. The end of the rotating shaft 15 and the snap-fit ​​groove 16 pass through and extend out of the rotating hole 14. A clamp 17 is snapped in the snap-fit ​​groove 16. The clamp 17 abuts against the edge of the rotating hole 14 to prevent the rotating shaft 15 from disengaging from the rotating hole 14. The gear 5 and the clamp 17 are located on both sides of the rotating hole 14. The diameters of the gear 5 and the clamp 17 are both larger than the diameter of the rotating hole 14.

[0034] Combination Figures 1-2 The feeding device 101 installed at the front end of the sliding member 3 can be a device for feeding the upper button of the button. The material support plate 102 is provided with a clearance groove for avoiding the button protrusion 201. The button protrusion 201 is located at the lower end of the button protrusion 202, and the button protrusion 201 is slidably placed in the clearance groove. The feeding device 101 clamps the button protrusion 202 to drive the movement of the button 200. The feeding device 101 for feeding the upper button is prior art. For the specific structure of the upper button feeding device 101, refer to Chinese Patent CN202321383187.9. The feeding pawl group and the upper feeding push rod in this patent are installed on the sliding member 3 in this embodiment. Or, combine Figures 5-6 The feeding device 101 installed at the front end of the sliding member 3 can be a device for feeding the lower button of the button. The feeding device 101 of the lower button is prior art. The specific structure of the feeding device 101 of the lower button can be referred to Chinese patent CN202421980884.7 and Chinese patent CN202421977974.0, which will not be described in detail here.

[0035] Example 2: The design scheme of this embodiment is basically the same as that of Embodiment 1, except that: This embodiment also includes a self-locking motor, which is mounted on the slide 1. The drive end of the self-locking motor is connected to the adjustment hole 10 of the gear 5 (in this embodiment, the drive component is a self-locking motor). The gear 5 is driven to rotate by the self-locking motor. The self-locking motor is controlled by the operating system of the button-attaching machine, thereby realizing the automation and digitization of the self-locking motor control, and thus ensuring the accuracy, automation and digitization of the rotation of the gear 5, that is, ensuring the automation and digitization of the sliding adjustment of the sliding component 3, and ensuring the accuracy and CNC automation of the height adjustment of the feeding device.

[0036] When the gear 5 is rotated by the self-locking motor, the locking component 7 does not lock the sliding member 3 and the guide block 2, so that the locking member 9 remains loose, allowing the sliding member 3 to slide on the guide block 2 and the guide block 2 to slide in the guide groove 4 (the guide block 2 does not disengage from the guide groove 4). The self-locking function of the self-locking motor restricts the sliding of the sliding member 3 on the guide block 2, and the self-locking function of the self-locking motor forms the locking structure.

[0037] Alternatively, when the gear 5 is rotated using a self-locking motor, this design does not include a locking component 7. The sidewalls of the guide block 2 and the guide groove 4 are both inclined, making the width of the groove opening smaller than the width of the bottom. The shape of the guide block 2 is adapted to the guide groove 4, i.e., the guide groove 4 is a dovetail groove and the guide block 2 is a dovetail block, thereby preventing the guide block 2 from detaching from the guide groove 4. The self-locking function of the self-locking motor restricts the sliding of the sliding member 3 on the guide block 2, and the self-locking function of the self-locking motor forms the locking structure.

[0038] Example 3: The design scheme of this embodiment is basically the same as that of Embodiment 1 or Embodiment 2, except that: Combination Figures 5-8 The rack 6 has a mounting part 11 on its side end. Several fasteners 12 are connected to the mounting part 11. The fasteners 12 are screws or bolts. The ends of the fasteners 12 pass through the mounting part 11 and are connected to the side end of the sliding member 3, so that the rack 6 is mounted on the rear end of the sliding member 3.

[0039] Example 4: The design scheme of this embodiment is basically the same as that of any one of Embodiments 1 to 3, except that: Combination Figures 5-8 A strip hole 8 is formed on the guide block 2; the front end of the locking member 9 passes through the strip hole 8 and is threadedly connected to the sliding member 3, and the locking part 18 abuts against the edge of the strip hole 8 to form the locking structure.
