[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1-4 As shown, this utility model provides a technical solution:

[0025] A mattress stitching reinforcement device, comprising:

[0026] Base 1, with a control panel 2 at the center of one side wall. Two pressing and fixing structures 3 are located at the front and rear of the center of the upper surface of base 1. Each pressing and fixing structure 3 includes two pressing brackets 301, respectively located at the front and rear of the center of the upper surface of base 1. Electric telescopic rods 302 are located on both sides of the center of the inner wall of each pressing bracket 301. The four electric telescopic rods 302 are arranged in pairs. Each pair of electric telescopic rods 302 has a pressing plate 303 at its output end. The lower surfaces of the two pressing plates 303 have four... Damping 304 is provided at each corner, and compression spring 305 is sleeved on the outside of each of the eight damping 304. The eight damping 304 are divided into groups of four. A buffer plate 306 is provided at the center of the lower end face of each of the two groups of damping 304. A rubber pad 307 is provided at the center of the lower end face of each of the two buffer plates 306. A locking block 308 is provided at the center of the upper end face of each of the two rubber pads 307, near the front and near the rear. A locking groove 309 is provided at the center of the lower end face of each of the two buffer plates 306, near the front and near the rear. The two locking blocks 308 are slidably connected to the center of the two locking grooves 309 respectively.

[0027] By activating the electric telescopic rod 302, the lower pressure plate 303 is extended, causing the cushioning plate 306 and rubber pad 307 to contact the mattress. The cushioning plate 306 and rubber pad 307 press down on the mattress, while the damping 304 and compression spring 305 provide cushioning, preventing the lower pressure plate 303 from causing a hard impact on the mattress when it presses down. At the same time, the friction between the rubber pad 307 and the mattress surface helps to stabilize the mattress. The sliding connection design of the locking block 308 and the locking groove 309 facilitates the installation and replacement of the rubber pad 307, so that it can be replaced in time when it wears out.

[0028] The upper surface of the base 1 is provided with two stitching structures 4 on both sides. The two stitching structures 4 include two lifting frames 401. The two lifting frames 401 are respectively located on both sides of the upper surface of the base 1. The center of one side wall of each of the two lifting frames 401 is provided with a first sliding groove 402. The center of the inside of each of the two first sliding grooves 402 is provided with a first lead screw 403. One end of each of the two first lead screws 403 passes through the inner wall of the two first sliding grooves 402 and the inner wall of the two lifting frames 401 and connects to the upper surface of the two lifting frames 401. The ends of each are fixedly connected to pulleys 404. The outer walls of the two pulleys 404 are fitted with belts. A connecting frame 405 is provided on the upper surface of one side of the lifting frame 401 on the outer side of one side of the pulley 404. A first servo motor 406 is provided at the center of the upper surface of the connecting frame 405. The output end of the first servo motor 406 is fixedly connected to one end of the pulley 404 on one side.

[0029] Two first lead screws 403 are threadedly fitted with adjustment frames 407 on their outer walls. The adjustment frames 407 are slidably connected to the center of the two first slide grooves 402. A second slide groove 408 is provided at the center of the lower end face of the adjustment frame 407. A connecting plate 409 is provided on one side of the center of the second slide groove 408. A second servo motor 410 is provided at the center of one side wall of the connecting plate 409. The output end of the second servo motor 410 passes through one side wall of the connecting plate 409 and extends to the other side wall of the connecting plate 409. A second lead screw 411 is fixedly connected to the end of the second lead screw 411. A sliding block 412 is threadedly fitted on the outer wall of the second lead screw 411. A stabilizing frame 413 is provided at the center of the lower end face of the sliding block 412. A rotator 414 is provided at the center of the inside of the stabilizing frame 413. The output end of the rotator 414 passes through the lower inner wall of the stabilizing frame 413 and extends to the lower end face of the stabilizing frame 413. A sewing machine body 415 is fixedly connected to the end of the rotator 414.

[0030] When the mattress needs to be sewn using the sewing structure 4, the first servo motor 406 is activated to drive the pulley 404 to rotate. Since the outer walls of the two pulleys 404 are fitted with belts, the other pulley 404 will rotate synchronously, thereby causing the two first lead screws 403 to rotate simultaneously. The rotation of the first lead screws 403 drives the adjusting frame 407 to move up and down along the first lead screws 403 within the first slide groove 402, thereby adjusting the height of the sewing machine body 415 to accommodate the sewing needs of mattresses of different thicknesses. Once the adjusting frame 407 is adjusted to the appropriate position, the second servo motor 406 is activated to start the sewing machine. The servo motor 410 drives the second lead screw 411 to rotate. The sliding block 412 is threaded on the outside of the second lead screw 411 and slidably connected in the second slide groove 408. As the second lead screw 411 rotates, it drives the sliding block 412 to slide in the second slide groove 408, thereby driving the stabilizing frame 413 installed on the lower end face of the sliding block 412, the rotator 414 inside the stabilizing frame 413, and the sewing machine body 415 to move horizontally. Furthermore, by starting the rotator 414, the sewing machine body 415 is started to rotate, and the sewing machine body 415 can perform sewing and reinforcement operations on the mattress.

[0031] A conveying structure 5 is provided at the center of the upper surface of the base 1. The conveying structure 5 includes a conveyor belt 501. The conveyor belt 501 is located at the center of the upper surface of the base 1. Multiple rollers 502 are arranged in a front-to-back pattern inside the center of the conveyor belt 501. A third servo motor 503 is provided at the front end of the upper side wall of the base 1. The output end of the third servo motor 503 is fixedly connected to one end of the front roller 502. When it is necessary to sew the edge of the mattress, the third servo motor 503 is started to drive the front roller 502 to rotate. Since the conveyor belt 501 is wrapped around multiple rollers 502, the multiple rollers 502 rotate with it, thereby driving the conveyor belt 501 to run. The mattress moves to the appropriate position below the pressing and fixing structure 3 and the sewing structure 4 via the conveyor belt 501.

[0032] The working principle of this utility model is as follows: When mattress stitching and reinforcement are required, after the mattress is placed on the conveyor belt 501, the third servo motor 503 is started through the control panel 2 to drive the front roller 502 fixedly connected to it to rotate. Since the conveyor belt 501 is wrapped around multiple rollers 502, there is an interrelated transmission relationship between each roller 502. Therefore, when the front roller 502 rotates, it drives the entire conveyor belt 501 to run. At this time, the mattress that needs to be stitched and reinforced placed on the conveyor belt 501 will be transported to the working area of ​​the device with the movement of the conveyor belt 501, preparing for the subsequent fixing and stitching operations.

[0033] After the mattress is delivered to the appropriate position, the downward pressing and fixing structure 3 begins to function. The electric telescopic rods 302 at the front and rear are activated via the control panel 2 to extend and retract as needed. When the electric telescopic rods 302 extend, they push the connected downward pressing plate 303 downwards. The dampers 304 installed at the four opposite corners of the lower end face of the downward pressing plate 303 begin to contact the mattress. As the downward pressing plate 303 continues to press down, the compression springs 305, compressed by the dampers 304, begin to contract, providing a certain amount of cushioning force to avoid hard impacts on the mattress, thus protecting it from damage. 304 drives the cushioning plate 306 and the rubber pad 307 on the lower end of the cushioning plate 306 to fit tightly against the mattress. The rubber pad 307 has a large friction force, which can effectively fix the mattress and prevent the mattress from moving or shaking during the sewing process, ensuring the accuracy and stability of the sewing. Moreover, the rubber pad 307 and the cushioning plate 306 are connected by a sliding connection of the locking block 308 and the locking groove 309. This design allows the rubber pad 307 to be easily removed and replaced when it is worn or damaged after long-term use, ensuring the stability of the downward pressure fixing effect.

[0034] When sewing is required, the first servo motor 406 is activated to drive the connected pulley 404 to rotate. Due to the transmission effect of the belt, the other pulley 404 and the first lead screw 403 will rotate synchronously. As the first lead screw 403 rotates, the adjusting frame 407 will move up or down along the first lead screw 403, thereby adjusting the height of the sewing machine components fixed to the lower end of the adjusting frame 407 to meet the height requirements when sewing mattresses of different thicknesses. After the height of the sewing machine body 415 is adjusted, the second servo motor 410 is activated to drive the second lead screw 411 fixedly connected to it to rotate. The sliding block 412 is threaded onto the second lead screw 411 and engages with the second lead screw 411. The groove 408 is slidably connected. As the second lead screw 411 rotates, the sliding block 412 slides horizontally along the second lead screw 411 within the second groove 408. This causes the stabilizing frame 413 fixed to the lower end face of the sliding block 412, the rotator 414 inside the stabilizing frame 413, and the sewing machine body 415 to move horizontally together. After the sliding block 412 is adjusted to a suitable horizontal position, the rotator 414 inside the stabilizing frame 413 is activated. The output end of the rotator 414 drives the sewing machine body 415 to rotate. At this time, the sewing needle of the sewing machine body 415 punctures and interweaves the thread in the area of ​​the mattress that needs to be sewn during the rotation, thereby achieving the sewing and reinforcement of the mattress.

[0035] Furthermore, the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0036] The preferred embodiments of the present invention have been described in detail above. 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.
