Description

Technical Field

[0001] This invention relates to the field of backrest and seat cushion production technology, and in particular to an automatic buttoning machine suitable for backrest and seat cushions. Background Technology

[0002] Backrest cushions are widely used in car seats, office chairs, and home sofas. Their structure typically consists of an inner cushion core and a cushion cover that encloses it. To prevent the cushion cover from slipping, wrinkling, or falling off during use, several sets of fasteners are used to secure the cushion cover to the inner cushion core during production. A common method is to install multiple fasteners on the cushion cover, which are then passed through the inner cushion core to achieve a secure connection between the cover and the core.

[0003] Currently, the above-mentioned buttoning operation mainly relies on manual labor. During the operation, the worker holds a crochet hook and manually inserts the hook through the inner core of the cushion one by one; then, the corresponding button is put on the cushion and hooked onto the hook; finally, the crochet hook is pulled back, which drives the button through the inner core to complete one buttoning. Since a single cushion usually needs six or more sets of buttons to be fixed, the worker needs to repeat the above operation many times, which is extremely tedious.

[0004] The traditional manual button-making method has obvious shortcomings: First, it involves many steps, is time-consuming, labor-intensive, and has low production efficiency; second, manual needle-by-needle piercing makes it difficult to guarantee positioning accuracy, and deviations in the piercing positions are prone to occur, affecting the consistency and appearance quality of the finished products; third, long-term repetitive manual piercing and needle-pulling actions can easily cause hand fatigue or even injury to the operator. Summary of the Invention

[0005] In view of the following problems with the existing traditional manual button-making method: firstly, the operation steps are numerous, time-consuming, labor-intensive, and inefficient; secondly, manual needle-by-needle threading makes it difficult to guarantee positioning accuracy, and deviations in the position of each hole are prone to occur, affecting the consistency and appearance quality of the finished product; and thirdly, long-term repetitive manual threading and needle-pulling actions can easily cause hand fatigue or even injury to the operator. Therefore, this invention is proposed.

The blocking block 318 can limit the transverse moving plate 314 so that the transverse moving plate 314 stops after moving to a designated position, ensuring the accuracy of the position movement.

[0025] The hook-and-loop fastener assembly 32 includes a first lifting plate 321 positioned above a transverse moving plate 314; a third electric push rod 327 fixedly mounted on the bottom of the transverse moving plate 314 near the first mounting plate 21, extending through a connecting slot 312 into the inner cavity of the device body 1; the output end of the third electric push rod 327 extending to the top of the transverse moving plate 314 and fixedly connected to the bottom of the first lifting plate 321; four sets of second limiting ring seats 329 positioned on the top of the transverse moving plate 314 near the first mounting plate 21, penetrating the transverse moving plate 314; and four sets of second limiting rods 328 positioned at the bottom of the first lifting plate 321, penetrating the second limiting ring seats 329. When the first lifting plate 321 moves up or down... When moving, the second limiting rod 328 can slide inside the second limiting ring seat 329, thereby improving the stability of the first lifting plate 321 when moving up and down.

[0026] The perforated assembly 33 includes a second lifting plate 331 disposed above the transverse moving plate 314, a fourth electric push rod 335 fixedly installed on the bottom of the transverse moving plate 314 away from the third electric push rod 327, and the output end of the fourth electric push rod 335 extends to the top of the transverse moving plate 314 and is fixedly connected to the bottom of the second lifting plate 331, four sets of third limiting ring seats 336 disposed on the top of the transverse moving plate 314 near the fourth electric push rod 335, and the third limiting ring seats 336 penetrate the transverse moving plate 314, and four sets of third limiting rods 337 disposed at the bottom of the second lifting plate 331, and the third limiting rods 337 penetrate the third limiting ring seats 336; The three sets of second mounting seats 332 at both ends of the top of the second lifting plate 331, the second piercing rod 333 at the top of the second mounting seat 332, and the spike 334 at the top of the second piercing rod 333 can be used to pierce the inner core of the seat cushion to create a hole.

[0027] The placement assembly 34 includes a placement top plate 341 disposed above the second mounting plate 311, three sets of fixed support rods 343 disposed at both ends of the bottom of the placement top plate 341, with the bottom ends of the fixed support rods 343 fixedly connected to the top of the second mounting plate 311, a limiting top plate 342 disposed above the placement top plate 341, two sets of fourth limiting ring seats 344 disposed on one side of the top ends of the placement top plate 341, with the fourth limiting ring seats 344 penetrating the placement top plate 341, main connecting blocks 347 disposed at both ends of one side of the bottom of the placement top plate 341, and connecting horizontal plates 346 slidably connected to both sides of the main connecting blocks 347. The fourth limiting rod 345 is set on both sides of the top of the connecting horizontal plate 346, and the top of the fourth limiting rod 345 passes through the fourth limiting ring seat 344 and is connected to the bottom of the limiting top plate 342. The three sets of limiting openings 348 are set at one end of the top of the limiting top plate 342. The limiting openings 348 are used to extend out of the limiting openings 348 after the spike 334 on the second piercing rod 333 pierces the inner core of the cushion, thus avoiding damage to the spike 334. The blocking back plate 349 is set at one end of the top of the placement top plate 341. The blocking back plate 349 blocks the inner core of the cushion.

[0028] The working principle of this invention is as follows: First, multiple sets of fixing rings 213 are sleeved on the surface of six sets of placement columns 211. Then, the seat cushion core can be placed above the placement top plate 341 and below the limiting top plate 342. Then, the weight of the limiting top plate 342 automatically moves down to assist in restricting the seat cushion core. At the same time, the fourth limiting rod 345 at the bottom of the limiting top plate 342 slides down below the fourth limiting ring seat 344, causing the connecting horizontal plate 346 to slide down on the surface of the main connecting block 347. At this point, by activating the first electric push rod 26, the two sets of side mounting brackets 28 on 37 are moved downward, causing the suction cup 29 to move above the fixing ring 213 and pick up the fixing ring 213. Then, the first electric push rod 26 is activated again to move upward and reset. Subsequently, the first electromagnetic slide rail 23 is activated, causing the first electromagnetic slider 24 to move laterally, thereby moving the mounting frame 25 above the first lifting plate 321. Then, the first electric push rod 26 is activated again to lower the suction cup 29 and place the fixing ring 213 on the suction cup 29 on the top of the collar 324. At the same time, the fourth electric push rod 335 is activated to drive the second lifting plate 331 to rise, which in turn drives the third limiting rod 337 to slide in the inner cavity of the third limiting ring seat 336. Then, the second lifting plate 331 moves upward so that the spike 334 on the second piercing rod 333 can pierce the seat cushion core placed on the top plate 341, piercing the seat cushion core through a hole. Then, the fourth electric push rod 335 is activated again to drive the second lifting plate 331 to fall and reset. Next, the second electromagnetic slide rail 313 is activated, causing the second electromagnetic slider 315 to move on the surface of the second electromagnetic slide rail 313, thereby moving the second lifting plate 331 to one side, while the first lifting plate 321 moves to the bottom of the seat cushion core placed on the top plate 341. Then, the third electric push rod 327 is activated to move the first lifting plate 321 upward, causing the second limiting rod 328 to slide in the inner cavity of the second limiting ring seat 329, while the hook part 326 passes through the piercing hole of the seat cushion core. At the same time, the fixing ring 213 and the collar 324 are blocked at the bottom of the seat cushion core. As the first lifting plate 321 continues to move upward, the first piercing rod 323 will pass through the hole, while the collar 324 and the fixing ring 213 will remain at the bottom of the seat cushion core, while the spring 325 is compressed. After the hook part 326 on the first piercing rod 323 penetrates the seat cushion core, the operator can hang the buckles on the seat cushion cover on the hook part 326 in sequence. Then, the third electric push rod 327 is activated again, causing the first lifting plate 321 to descend and reset. This allows the hook part 326 to retract from above the seat cushion core to below, thereby driving the buckle to pass through the fixing ring 213 on the seat cushion core and the collar 324. Then, the automatic buckling operation of the seat cushion core and the seat cushion cover is completed. At this time, the buckled seat cushion core placed on the top plate 341 can be removed, replaced with a new seat cushion core, and the above steps can be repeated. As the number of fixing rings 213 on the column 211 on the movable support plate 210 decreases, the movable support plate 210 can be moved upward by activating the second electric push rod 20. At the same time, the first limiting rod 212 slides in the inner cavity of the first limiting ring seat 214, which allows the movable support plate 210 to push the fixing rings 213 up on the surface of the column 211, so that the suction cup 29 on the mounting frame 25 can easily grab the fixing rings 213.
