Description

Technical Field

[0001] This utility model relates to the field of button auxiliary equipment technology, specifically to a multi-functional button attaching machine. Background Technology

[0002] Traditional hand-sewing of buttons relies on needle and thread, which is not only tedious and time-consuming, but also has the following problems: First, the button positioning accuracy is low, and hand sewing can easily lead to misalignment between the top and bottom buttons, affecting the functionality; second, the tightness of the thread is difficult to control. If it is too loose, the button will fall off, and if it is too tight, the fabric may wrinkle, damaging the appearance of the product; third, the applicability is limited. For hard buttons such as metal and plastic buttons, hand sewing is difficult and can easily cause the button to break or the fabric to tear due to uneven force.

[0003] Existing semi-automatic or small button-attaching tools also have significant shortcomings: some tools use a single mold design, which can only adapt to buttons of specific sizes or types. When changing button specifications, the entire mold needs to be replaced, which is complicated and costly; some button-attaching machines lack an effective limiting structure, which can easily cause mold collision damage due to uncontrolled force when pressing, or cause button misalignment due to deviation in pressing angle; some tools have an unreasonable spring return structure design, with insufficient or excessive return force, resulting in poor operating feel and easy hand fatigue with long-term use.

[0004] In home craft settings, existing button-sewing tools are often bulky and heavy, making them inconvenient to store and carry. Small handheld tools, on the other hand, suffer from fragile structures, short lifespans, and parts that are prone to loosening when pressed. In small workshops with mass production, existing tools are inefficient, requiring multiple positioning and pressing steps for each button, which cannot meet the demands of rapid processing and results in inconsistent sewing quality.

[0005] Furthermore, existing button-attaching tools generally lack ergonomic design, with the grip area often being a straight, hard shell structure, which can easily lead to pressure and pain in the palm and fingers with prolonged use; some tools also lack safety protection structures, with the mold exposed when pressing, posing a risk of pinching fingers. Therefore, developing a multi-functional button-attaching machine that combines multi-size button compatibility, precise positioning, labor-saving operation, durable structure, and safety protection is key to solving the above problems. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned problems and provide a multifunctional button-attaching machine. To achieve the above objective, this utility model adopts the following technical solution:

[0007] A multifunctional button attaching machine includes a button attaching base and a pressing handle. The front end of the button attaching base is hinged to the front end of the pressing handle. A pressing post is provided at the bottom of the pressing handle, and the pressing post passes through the top of the button attaching base. A spring is sleeved on the pressing post and fixed between the bottom of the pressing handle and the top of the button attaching base. A mold head is screwed to the bottom of the pressing post, and a mold base is provided on the bottom of the button attaching base. The pressing post, mold head, and mold base are located on the same straight line. A bottom button is placed on the mold base, and a top button is installed at the bottom of the mold head. Fabric is placed between the bottom button and the top button. Pressing the pressing handle fixes the bottom button and the top button on the fabric.

[0008] As an improvement, the top of the buckle seat is provided with a limiting bolt, which is located on the rear side of the pressing column and below the pressing handle.

[0009] As an improvement, the rear end of the buckle seat is provided with a limiting ring, which is sleeved on the rear end of the press handle.

[0010] As an improvement, a connecting block is provided between the front end of the fastener seat and the front end of the pressing handle, and the two ends of the connecting block are respectively hinged to the front end of the fastener seat and the front end of the pressing handle.

[0011] As an improvement, the rear end of the pressing handle and the buckle seat is provided with a gripping arc surface.

[0012] As an improvement, the pressing column includes an upper structure and a lower structure, the upper structure being fixed to the bottom of the pressing handle, and the bottom of the upper structure being arc-connected to the top of the lower structure.

[0013] The advantages of this utility model are:

[0014] 1. This utility model improves binding efficiency and accuracy. Through the lever structure and elastic reset design, the binding time for a single button is shortened, and the efficiency is improved. The coaxial positioning of the mold components and the adjustment of the limit bolts ensure that there is no misalignment between the front and bottom buttons, thus completely solving the problems of misalignment and falling off during manual binding.

[0015] 2. This utility model is adaptable to multiple specifications, reducing the cost of use. The modular mold head and mold base can be adapted to various specifications of face buttons and bottom buttons, such as round, square, and irregular shapes. It can quickly change molds and eliminates the need to equip multiple machines for different buttons, thus reducing equipment procurement costs.

[0016] 3. This utility model is easy to operate and suitable for long-term use. The lever structure design reduces the pressure required to press down and significantly reduces hand fatigue. The ergonomic design of the curved grip surface and the anti-slip texture reduce pressure and pain on the palm, improving operating comfort. It is especially suitable for long-term use by home craft enthusiasts and small workshop workers. Attached Figure Description

[0026] The present invention will be described in detail below through specific embodiments to enable a better understanding of the present invention. However, the following embodiments do not limit the scope of protection of the present invention.

[0027] Example 1

[0028] This embodiment discloses a multifunctional button attaching machine.

[0029] like Figure 1 , Figure 2 As shown, this embodiment includes a button holder 1, a pressing handle 2, an elastic component, a mold component, and a limiting and protective structure. The pressing handle 2 drives the mold component to close, thus fixing the face button and the bottom button to the fabric. The specific structure and function are as follows:

[0030] Core structure and functions

[0031] Main support structure: It consists of a buckle seat 1 and a pressing handle 2. The front ends of the two are hinged to form a lever structure, and the rear end is the gripping and operating area. The whole is made of high-strength engineering plastic, which is both lightweight and durable and can withstand long-term pressing impact without deformation.

[0032] Nail holder 1: It is U-shaped and serves as the basic support for the entire device. The bottom is flat and easy to place on the workbench. The top has a through hole for the pressing column 3 to pass through. The front end is hinged to the pressing handle 2 through the connecting block 9. The rear end has a limiting ring 8 and a gripping arc surface 10.

[0033] Press handle 2: It is symmetrically arranged with the buckle seat 1. The front end is hinged to the buckle seat 1 through the connecting block 9. The bottom is fixed with the pressing column 3. The rear end is provided with a grip arc surface 10 that fits the palm. The arc surface adopts an anti-slip texture design to increase grip friction. At the same time, it fits the curve of the human palm, reducing the pressure of long-term operation, which is in line with the ergonomic principle.

[0034] Elastic reset component: including pressing column 3 and spring 4, is the core of driving the mold assembly to reset and controlling the pressing force.

[0035] Pressing column 3: Vertically fixed to the bottom of pressing handle 2, passing through the through hole at the top of the buckle seat 1, with external threads at the bottom for screwing the mold head 5, allowing for quick replacement of different specifications of mold head 5 by rotation; the pressing column 3 and the through hole are fitted with a clearance to ensure vertical movement during pressing and avoid mold misalignment. The pressing column 3 includes an upper structure 11 and a lower structure 12. The upper structure 11 is fixed to the bottom of pressing handle 2, and the bottom of the upper structure 11 is arc-connected to the top of the lower structure 12. The arc connection ensures the vertical setting of the lower structure 12.

[0036] Spring 4: Sleeves on the outside of the pressing post 3, with both ends fixed to the bottom of the pressing handle 2 and the top of the fastener seat 1 respectively. In its natural state, it is in a stretched state, providing a return force for the pressing handle 2. When pressed, the spring 4 is compressed to store energy. After being released, the spring 4 rebounds and drives the pressing handle 2 to return to its original position. No manual lifting is required, making operation easier. The spring force of the spring 4 can be selected according to the needs to ensure that it provides sufficient binding pressure without causing operational difficulties due to excessive spring force.

[0037] Mold assembly: Adopting a modular design, it includes a mold head 5 and a mold base 6, both coaxially arranged, and can be flexibly replaced according to the button specifications.

[0038] Mold head 5: The bottom is provided with a groove that matches the face buckle. Different sizes of face buckles (such as round, square, diameter 5-20mm) correspond to different groove sizes of mold heads 5. They are connected to the bottom of the pressing column 3 by screwing. When replacing, simply rotate to remove the old mold head 5 and install the new mold head 5.

[0039] Mold base 6: Fixed to the bottom of the buckle seat 1, with a protrusion or groove on the top that matches the bottom buckle, so that the bottom buckle can be placed stably on it, corresponding to the groove of the mold head 5; the mold base 6 and the buckle seat 1 are connected by a snap-fit, which can be quickly disassembled and replaced to accommodate bottom buckles of different specifications.

[0040] Limiting and protective structure: including limiting bolt 7, limiting ring 8 and connecting block 9, to ensure operational safety and binding accuracy.

[0041] Limiting bolt 7: Threaded connection to the top of the fastener seat 1, located behind the pressing column 3 and below the pressing handle 2. The extension height can be adjusted by rotation. When the pressing handle 2 is pressed down, the top of the limiting bolt 7 contacts the bottom of the pressing handle 2, limiting the maximum pressing stroke and preventing the mold head 5 from being pressed down excessively, which could cause mold collision damage or fabric damage. At the same time, the limiting height can be adjusted according to the fabric thickness (such as thin yarn or thick denim) to ensure that the binding pressure is suitable for different materials.

[0042] Limiting ring 8: Fixed to the rear end of the buckle seat 1, it is semi-circularly sleeved around the rear end of the pressing handle 2. It can limit the left and right swing range of the pressing handle 2, prevent the mold components from being misaligned due to hand deviation when pressing, and ensure that the face buckle and the bottom buckle are accurately aligned. At the same time, the limiting ring 8 can prevent the rear end of the pressing handle 2 from tilting up excessively, and prevent the hand from accidentally slipping off during operation.

[0043] Connecting block 9: Both ends are hinged to the front end of the buckle seat 1 and the front end of the pressing handle 2 respectively, which enhances the wear resistance of the hinged parts and prevents loosening after long-term use; the length of connecting block 9 is fixed to ensure that the hinge angle between the buckle seat 1 and the pressing handle 2 is stable, and further improves the verticality of the pressing process.

[0044] Working principle

[0045] Mold replacement and adjustment: Select the appropriate mold head 5 and mold base 6 according to the specifications of the buttons to be attached. Screw the mold head 5 to the bottom of the pressing column 3 and fix the mold base 6 to the bottom of the button holder 1. Rotate the limit bolt 7 and adjust the limit height according to the fabric thickness to ensure that the face button and the bottom button can be tightly fixed when the mold head 5 is pressed down, without damaging the fabric.

[0046] Material placement: Place the bottom buckle into the appropriate position on the mold base 6, ensuring that the bottom buckle is stable and does not shift; lay the fabric to be attached to the bottom buckle flat on top of the bottom buckle, and adjust the position of the fabric so that the attachment point is aligned with the center of the bottom buckle; place the top buckle into the groove at the bottom of the mold head 5, ensuring that the top buckle corresponds to the bottom buckle.

[0047] Press-fit: Hold the gripping arc surface 10 of the fastener seat 1 and the press handle 2 respectively, and press the press handle 2 downward. The press handle 2 rotates around the front hinge point, which drives the press column 3 and the mold head 5 to move vertically downward, and the spring 4 is compressed. When the mold head 5 contacts the face buckle, continue to apply pressure so that the face buckle and the bottom buckle are tightly fastened to the fabric through their own snap-fit ​​structure. At this time, the bottom of the press handle 2 contacts the limit bolt 7, reaching the maximum pressing stroke, and the pressing stops.

[0048] Reset and remove the part: Release the pressing handle 2, the spring 4 rebounds and drives the pressing handle 2, pressing column 3 and mold head 5 to reset upward; remove the fabric to complete the binding of a single button; if continuous binding is required, repeat steps 2-4.
