Description

Technical Field

[0001] This utility model relates to the field of button-attaching machine technology, and in particular to a spacing adjustment mechanism and its integrated punching and button-attaching machine. Background Technology

[0002] In the manufacturing of textile products such as clothing, bags, and home textiles, the buttoning process is a crucial step in ensuring the structural integrity and functionality of products. Its processing precision directly affects the product's appearance and durability. With the increasing market demand for personalized and diversified textile products, the spacing requirements for punching and buttoning are becoming more varied for different specifications and styles. This places higher demands on the flexibility and precision of buttoning equipment's spacing adjustment. Currently, the buttoning machines widely used in the industry still primarily rely on traditional manual operation for adjusting the punching and buttoning spacing. Specifically, operators must hold both ends of the fabric with their hands and manually move the fabric according to product design requirements or experience to adjust the relative distance between the processing position and the buttoning machine head, thereby achieving different punching and buttoning spacing.

[0003] However, the spacing adjustment effect is highly dependent on the operator's experience level. Experienced operators need long-term practical experience to accurately control the fabric movement distance. Inexperienced operators, when manually moving the fabric, are prone to uneven force control and visual judgment deviations, resulting in lateral offset and longitudinal misalignment of the punching and buttoning positions. In severe cases, this can cause fabric scrapping, increasing production costs. At the same time, manual fabric movement is inefficient and cannot meet the high-speed processing requirements of modern production lines. Furthermore, prolonged repetitive handling and movement significantly increases the operator's labor intensity, easily leading to fatigue and further exacerbating the risk of position misalignment. Therefore, this application aims to solve the problem of existing integrated machines relying on manual adjustment, namely, the problem that this operation is prone to punching misalignment and fabric loss due to differences in operator experience, and is inefficient and labor-intensive, unable to meet the needs of modern high-speed production, significantly restricting production efficiency and increasing costs. Therefore, a spacing adjustment mechanism and its punching and buttoning integrated machine are proposed. Utility Model Content

[0004] To overcome the problem that existing punching and button-attaching machines rely heavily on operator experience for spacing adjustment during the punching and button-attaching process, skilled operators need extensive practice to accurately control the movement distance, while novices often cause horizontal and vertical misalignment during punching and button-attaching due to uneven force and visual deviations, even resulting in fabric scrap and increased costs. In addition, manual operation is inefficient, difficult to match the high-speed demands of modern production lines, and involves repetitive labor that easily leads to fatigue, further increasing the risk of misalignment.

[0005] The technical solution of this utility model is as follows: a spacing adjustment mechanism includes a placement seat, an mounting block is provided on the inner side of the placement seat, an mounting strip is connected to the lower end face of the mounting block, the mounting strip is fixedly connected to the placement seat, and a traveling roller is also included. Several traveling rollers are respectively distributed on both sides of the placement seat, and the number of traveling rollers distributed on both sides of the placement seat is set to be the same. A driving component is connected to the traveling roller, and the driving component is used to drive the traveling roller to rotate around its own central axis. A rotation counter is connected to one of the traveling rollers, and the rotation counter is used to obtain the number of rotations of the traveling roller.

[0006] Preferably, the lower end face of the placement seat is connected to a fixed seat, the upper end face of the fixed seat is connected to a connecting piece, a rotating rod is rotatably connected to the connecting piece, and a fixed piece is connected to the rotating rod.

[0007] Preferably, a guide rod is connected to the upper end face of the fixed plate, a movable plate is sleeved on the guide rod, a connecting post is connected to the upper end face of the movable plate, and a return spring is connected between the movable plate and the fixed plate.

[0008] Preferably, a combination frame is connected to the connecting column, a rotating handle is connected to the upper end face of the combination frame, a connecting piece is connected to the combination frame, and a fixing frame is connected to the lower end face of the connecting piece.

[0009] Preferably, a connecting roller frame is connected to the fixed frame, a connecting roller is rotatably connected to the connecting roller frame, a synchronous pressure belt is sleeved on the connecting roller, a connecting shaft is connected to one of the connecting rollers, a first bevel gear is connected to the connecting shaft, a second bevel gear is provided on one side of the first bevel gear, the teeth of the second bevel gear mesh with the teeth of the first bevel gear, a rotating shaft is connected to the second bevel gear, a first motor is connected to the rotating shaft, and the first motor is connected to the fixed frame.

[0010] Preferably, the drive assembly includes a timing pulley connected to a travel roller, a timing belt sleeved on the outer side of the timing pulley, and a second motor connected to the travel roller which is connected to a rotation counter.

[0011] A punching and fastening machine with a spacing adjustment mechanism includes a material placement base, which is fixedly connected to a fixed base. A connecting base is connected to the lower end of the material placement base, and a working head is connected to the upper end of the material placement base. A first feeding slide rail is provided on one side of the material placement base, and a first part vibrating plate is connected to one side of the first feeding slide rail. The first part vibrating plate is connected to the connecting base. A second feeding slide rail is provided on the other side of the material placement base, and a second part vibrating plate is connected to one side of the second feeding slide rail. The second part vibrating plate is connected to the connecting base.

[0012] The beneficial effects of this utility model are: 1. When it is necessary to move the fabric, the drive component can drive the travel roller to rotate, and the number of rotations of the travel roller can be recorded by the rotation counter. When the number of rotations reaches the rated value, the drive component can be stopped, so that the working head can punch holes and fasten buttons on the fabric. The device can adjust the spacing of the punched buttons by adjusting the number of rotations in conjunction with the rotation counter. 2. The synchronous pressing belt is driven by friction. The synchronous pressing belt and the traveling roller will clamp and force the fabric to be conveyed. Since the upper and lower surfaces of the fabric are clamped by materials with a high coefficient of friction, slippage is minimized. Thus, by increasing the clamping area, slippage is eliminated. 3. The spring structure formed by the return spring and the guide rod allows the synchronous pressure belt to be automatically lifted when thick fabric is placed into the device, compressing the return spring. At the same time, because the return spring is compressed, the pressure applied to the fabric remains unchanged. This solves the problem that when the same number of turns is used for fabrics of different thicknesses, the same number of turns will result in different actual movement distances, which means that the device needs to be recalibrated for punching holes and attaching buttons to fabrics of different thicknesses.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example 1 refer to Figure 1 The structure shown is a spacing adjustment mechanism, including a placement seat 401, an mounting block 403 is provided on the inner side of the placement seat 401, an mounting strip 402 is connected to the lower end face of the mounting block 403, the mounting strip 402 is fixedly connected to the placement seat 401, and also includes a traveling roller 501, a plurality of traveling rollers 501 are respectively distributed on both sides of the placement seat 401, and the number of traveling rollers 501 distributed on both sides of the placement seat 401 is set to be the same. A driving component is connected to the traveling roller 501, the driving component is used to drive the traveling roller 501 to rotate around its own central axis, and a rotation counter 505 is connected to one of the traveling rollers 501, the rotation counter 505 is used to obtain the number of rotations of the traveling roller 501.

[0017] Among them, the front and rear ends of the placement base 401 are rotatably connected to several auxiliary wheels 404, and the auxiliary wheels 404 are rotatably connected to the connecting strip 405; When the fabric needs to be moved, the travel roller 501 can be driven to rotate by the drive component, and the number of rotations of the travel roller 501 is recorded by the rotation counter 505. When the number of rotations reaches the rated value, the drive component can be stopped, so that the working head 11 can punch holes and fasten buttons on the fabric. This allows the device to adjust the spacing of the punched buttons by adjusting the number of rotations coordinated with the rotation counter 505.

[0018] Furthermore, the drive assembly includes a timing pulley 502, which is connected to the travel roller 501. A timing belt 503 is sleeved on the outer side of the timing pulley 502, and a second motor 504 is connected to the travel roller 501, which is connected to the rotation counter 505.

[0019] The second motor 504 is generally a stepper motor of model 17HS08-1004S used in conjunction with it.

[0020] Example 2 Based on the above embodiment 1, in order to address the issue that the friction between the travel roller 501 and the fabric is the driving force and also the main source of error, the material, humidity, and surface treatment of the fabric will significantly affect the friction. Even a slight slippage will cause the value recorded by the rotation counter 505 to differ from the actual distance the fabric has moved, resulting in a cumulative error in the button position. This error becomes increasingly pronounced with the increase in the number of buttons, thus affecting the working efficiency of the device. (Refer to...) Figures 2-5 The structure shown; Unlike Embodiment 1, the lower end face of the placement seat 401 is connected to a fixed seat 101, the upper end face of the fixed seat 101 is connected to a connecting piece 102, a rotating rod 103 is rotatably connected to the connecting piece 102, and a fixed piece 104 is connected to the rotating rod 103.

[0021] Furthermore, a guide rod 105 is connected to the upper end face of the fixed plate 104, a movable plate 106 is sleeved on the guide rod 105, a connecting post 108 is connected to the upper end face of the movable plate 106, and a return spring 107 is connected between the movable plate 106 and the fixed plate 104.

[0022] The spring structure formed by the return spring 107 and the guide rod 105 allows the synchronous pressure belt 303 to be automatically lifted when thick fabric is placed into the device, compressing the return spring 107. At the same time, because the return spring 107 is compressed, the pressure applied to the fabric remains unchanged. This solves the problem that when the same number of turns is used for fabrics of different thicknesses, the same number of turns will result in different actual movement distances, which means that the device needs to be recalibrated for punching holes and attaching buttons to fabrics of different thicknesses.

[0023] Furthermore, a combination frame 201 is connected to the connecting column 108, a rotating handle 202 is connected to the upper end face of the combination frame 201, a connecting piece 203 is connected to the combination frame 201, and a fixing frame 204 is connected to the lower end face of the connecting piece 203.

[0024] Furthermore, a connecting roller frame 301 is connected to the fixed frame 204, and a connecting roller 302 is rotatably connected to the connecting roller frame 301. A synchronous pressure belt 303 is sleeved on the connecting roller 302. A connecting shaft 304 is connected to one of the connecting rollers 302, and a first bevel gear 305 is connected to the connecting shaft 304. A second bevel gear 306 is provided on one side of the first bevel gear 305. The teeth of the second bevel gear 306 mesh with the teeth of the first bevel gear 305. A rotating shaft 307 is connected to the second bevel gear 306, and a first motor 308 is connected to the rotating shaft 307. The first motor 308 is connected to the fixed frame 204.

[0025] The outer side of the second bevel gear 306 is provided with a protective cover 309, which is connected to the fixed frame 204. The protective cover 309 is used to isolate the second bevel gear 306 from the external environment, prevent dust from entering the meshing area and affecting the transmission accuracy, and at the same time avoid the operator from accidentally touching the rotating parts and causing safety accidents. The overall structure is compact, ensuring the stable operation and maintenance safety of the transmission system. The first motor 308 is generally a stepper motor of model 17HS08-1004S. When the fixed frame 204 is in a horizontal state, the bottom end of the synchronous pressure belt 303 contacts the top end of the fabric. When the first motor 308 drives the second bevel gear 306 to rotate, it can synchronously drive the first bevel gear 305 to rotate, so that the rotating first bevel gear 305 drives the connecting shaft 304 to rotate, thereby enabling the connecting shaft 304 to drive the connecting roller 302 to rotate, so that the synchronous pressing belt 303 can rotate synchronously, thereby achieving the pressing of the upper end of the fabric. This allows the connecting roller 302 to drive the synchronous pressure belt 303 through friction during rotation. The synchronous pressure belt 303 and the traveling roller 501 will jointly clamp and forcefully convey the fabric. Since the upper and lower surfaces of the fabric are clamped by materials with a high coefficient of friction, slippage is minimized. This is achieved by increasing the clamping area to eliminate slippage.

[0026] A punching and fastening machine with a spacing adjustment mechanism includes a material placement seat 8, which is fixedly connected to a fixed seat 101. A connecting seat 12 is connected to the lower end of the material placement seat 8, and a working head 11 is connected to the upper end of the material placement seat 8. A first feeding slide rail 7 is provided on one side of the material placement seat 8, and a first part vibrating plate 6 is connected to one side of the first feeding slide rail 7. The first part vibrating plate 6 is connected to the connecting seat 12. A second feeding slide rail 9 is provided on the other side of the material placement seat 8, and a second part vibrating plate 10 is connected to one side of the second feeding slide rail 9. The second part vibrating plate 10 is connected to the connecting seat 12.

[0027] The first feeding slide rail 7 and the second feeding slide rail 9 are both configured as a combination of feeding rail and clamping robot. The feeding rail drives the parts inside the vibratory plate to move to the clamping robot, and the clamping robot grabs the button from the feeding rail and moves it to the buttoning position. The working head 11 includes a switching slide rail, a punching head, a punch rod, and cylinders connected to the upper ends of the punching head and the punch rod respectively. By driving the cylinder at the upper end of the punching head to move, the punching head punches holes in the fabric. After punching is completed, the switching slide rail moves the punch rod to the punching head. By driving the cylinder at the upper end of the punch rod to move, the punch rod presses the button's pin into the fabric and bends or punctures it to form a rivet, thereby realizing the punching and buttoning process of the fabric.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
