[0015] A method for sewing mattress edging fabric to a fixed length, the method using the aforementioned mattress edging fabric cutting and sewing equipment, includes the following steps:

[0016] S1. Place the rolled binding tape onto the vertical bar of the placement tray, then pull the end of the binding tape to pass through the conveying assembly and the guide assembly in sequence, and then place the end at the working position of the sewing machine body.

[0017] S2. Place the mattress to be edged on the placement table, and sew the beginning part of one end of the mattress by manually pulling it. Then insert the sewn end into the U-shaped board and firmly clamp the end of the mattress by the clamping component.

[0018] S3, the PLC controller controls the conveyor assembly to drive the binding tape to be continuously conveyed forward, and the rotary encoder inside the conveyor assembly synchronously records the number of rotations of the conveyor rollers to accurately calculate the conveying length of the binding tape. Then, the moving assembly drives the U-shaped plate and the mattress clamped and fixed to move at a uniform speed, and in coordination with the conveying speed of the binding tape, the sewing machine body continuously performs binding and sewing operations on the mattress.

[0019] S4. When the rotary encoder detects that the conveying length of the binding tape has reached the preset value, it transmits the signal to the PLC controller.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The mattress edging fixed-length cutting and sewing equipment and method of the present invention accurately records the number of rotations of the conveying rollers through the internal rotary encoder of the conveying component, thereby accurately calculating the conveying length of the edging tape, realizing fixed-length feeding, and completing automatic fixed-length cutting with the fabric cutting component.

[0022] 2. The mattress binding and fixed-length cutting and sewing equipment and method of the present invention, by setting a moving component and a clamping component, clamps and fixes the sewn end of the mattress, which can drive the mattress to move at a uniform speed to cooperate with the conveying and sewing operation of the binding tape. There is no need for manual continuous pulling of the mattress to move, which reduces the intensity of manual labor, further ensures the stability of the sewing process, and improves the overall processing efficiency and sewing quality.

[0023] 3. In the mattress binding and sewing equipment and method of the present invention, the spring will always push the slider to move closer to the conveyor roller, causing the limiting roller to fit tightly against the outer surface of the conveyor roller. When the binding tape passes between the limiting roller and the conveyor roller, the binding tape can be pressed tightly against the surface of the conveyor roller, preventing the binding tape from slipping and loosening during the conveying process, ensuring the accuracy of the conveying length measurement, and at the same time, it can adapt to binding tapes of different thicknesses. The limiting roller can adaptively adjust its position according to the thickness of the binding tape to maintain the stability of the pressing force, so that the conveyor roller is more stable during the conveying process. At the same time, after the cutting component cuts, the cut end of the binding tape can be clamped by the limiting roller and the conveyor roller, and it is convenient to pull it out again for use through the guide component, making it convenient to use.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] like Figures 1 to 8 As shown in the figure, a mattress edge binding and fixed-length cutting and sewing device according to an embodiment of the present invention includes a placement table 1, and a support table 3 is fixedly connected to the front surface of the placement table 1.

[0037] The sewing machine body 2 is fixedly installed on the top of the support platform 3. A guide plate 8 is fixedly connected to the front left side of the top of the support platform 3. An L-shaped support plate 9 is fixedly connected to the top of the guide plate 8. A guide component is provided inside the guide plate 8. A conveying component is provided between the L-shaped support plate 9 and the support platform 3. A fabric cutting component is provided on the L-shaped support plate 9.

[0038] A through slot 27 is provided on the front right side of the placement platform 1. A moving component is installed inside the slot 27, and the top of the moving component extends to the top of the placement platform 1. A U-shaped plate 5 is provided on the U-shaped plate 5, and a clamping component is provided on the U-shaped plate 5. A PLC controller 4 is fixedly installed on the lower right side of the front surface of the placement platform 1. During operation, the bottom of the placement platform 1 and the support platform 3 are first aligned with a flat ground to ensure the stability of the equipment. After the equipment is stabilized, the mattress that needs to be edged is placed on the placement platform 1. Then, the edge of the mattress is aligned with the sewing area of ​​the sewing machine body 2. During sewing, the edge binding tape is conveyed to the edge of the mattress through the conveying component and the guiding component, and then sewn by the sewing machine body 2. One end of the mattress is held by a clamping component, which can be moved by a moving component. The moving component then pulls the clamping component to pull the mattress, and together with the conveying component, the edge binding tape is conveyed to perform edge binding. The conveying component can also convey the mattress to a fixed length. When the conveyed length is reached, the edge binding tape can be cut by the cutting component, which facilitates the fixed-length cutting and sewing operation of the mattress edge binding. The equipment can be controlled by a PLC controller 4. When switching sides during the mattress edge binding process, manual handling is required to switch the other side of the mattress. The circumference data of the entire mattress is pre-entered into the equipment. After the fixed-length edge binding tape is conveyed, it is cut.

[0039] In a preferred embodiment of the present invention, the conveying assembly includes a conveying roller 14 rotatably mounted between the right side of the L-shaped support plate 9 and the support platform 3. A motor 12 is fixedly mounted on the top of the L-shaped support plate 9, with its output end extending into the interior of the L-shaped support plate 9 and fixedly connected to the top of the conveying roller 14. A rotary encoder 13 is fixedly mounted on the outer surface of the roller shaft of the conveying roller 14 inside the L-shaped support plate 9. A placement tray 7 is rotatably mounted on the top right side of the support platform 3, and a vertical rod is fixedly connected to the top of the placement tray 7. During operation, the rolled edge banding is placed over the vertical rod at the top of the placement tray 7, and the vertical rod initially limits the movement of the rolled edge banding to prevent it from rolling out. If the binding tape falls or becomes misaligned during the conveying process, the end of the binding tape is pulled around the conveyor roller 14 and can be conveyed through the conveyor roller 14. After passing the conveyor roller 14, the end of the binding tape is pulled to the sewing machine body 2 by the guide component. At the same time, the motor 12 drives the conveyor roller 14 to rotate and convey the binding tape. The rotary encoder 13 rotates synchronously with the conveyor roller 14 to accurately record the number of rotations of the conveyor roller 14, and then calculates the conveying length of the binding tape. The length data is transmitted to the PLC controller 4. When the preset fixed length value is reached, the PLC controller 4 controls the motor 12 to stop conveying and triggers the fabric cutting component to complete the cutting, realizing the automated fixed-length conveying and cutting of the binding tape.

[0040] In a preferred embodiment of the present invention, a sliding groove 16 is provided on the left side of the side of the L-shaped support plate 9 opposite to the support platform 3. A slider 17 is slidably connected inside the sliding groove 16. A spring 21 is fixedly connected between the slider 17 and the sliding groove 16. A limiting roller 15 is rotatably installed between the two sliders 17. The outer surface of the limiting roller 15 is in contact with the outer surface of the conveying roller 14. During operation, the spring 21 will always push the slider 17 to move closer to the conveying roller 14, causing the limiting roller 15 to be tightly in contact with the outer surface of the conveying roller 14. When the binding tape passes through the limiting roller 15, the limiting roller 15 will be in close contact with the outer surface of the conveying roller 14. When the limit roller 15 is between the conveyor roller 14 and the limit roller 15, the binding tape can be pressed tightly onto the surface of the conveyor roller 14 to prevent the binding tape from slipping and loosening during the conveying process, ensuring the accuracy of the conveying length measurement. At the same time, it can adapt to binding tapes of different thicknesses. The limit roller 15 can adaptively adjust its position according to the thickness of the binding tape to maintain the stability of the pressing force, so that the conveyor roller 14 is more stable during the conveying process. In addition, when the fabric cutting assembly cuts the binding tape, the cut end can be clamped by the limit roller 15 and the conveyor roller 14, which facilitates subsequent pulling out and passing through the guide assembly for use, making it convenient to use.

[0041] In a preferred embodiment of the present invention, a through hole 20 is provided on the left side of the slide groove 16, through which a pull rod 19 slides. A spring 21 passes through the right end of the pull rod 19, and the right end of the pull rod 19 is fixedly connected to the left side of the slider 17. A handle plate 18 is fixedly connected between the left ends of the two pull rods 19. During operation, when it is necessary to insert the binding tape, pulling the handle plate 18 will cause the two pull rods 19 to slide to the left along the through hole 20 at the same time, thereby pulling the two sliders 17 to move to the left along the slide groove 16, compressing the spring 21 and causing the limiting roller 15 to move away from the conveying roller 14, so that there is enough space between the limiting roller 15 and the conveying roller 14 for the user to quickly insert the end of the binding tape. After insertion, the handle plate 18 is released, the spring 21 returns to its original position, and pushes the slider 17 and the limiting roller 15 to return to their original position and press the binding tape, making the tape insertion operation simpler and more convenient.

[0042] In a preferred embodiment of the present invention, the guiding component includes a through mounting groove 22 formed inside the guide plate 8. Rotating rods 24 are rotatably mounted at both the front and rear of the mounting groove 22. Guide wheels 23 are fixedly connected to the outer surface of the rotating rods 24. During operation, the binding tape passes between the two guide wheels 23. The two guide wheels 23 guide and limit the binding tape, preventing it from shifting or skewing during transport, ensuring that the binding tape is always transported in a straight line to the sewing position, improving the accuracy of the binding tape position during sewing. Furthermore, a U-shaped space can be formed between the guide wheels 23 and the mounting groove 22, allowing the guided binding tape to output in a U-shape corresponding to the edge of the mattress, thus facilitating subsequent sewing. Simultaneously, the guide wheels 23 can rotate synchronously with the movement of the binding tape, without obstructing its transport, ensuring a smooth transport process.

[0043] In a preferred embodiment of the present invention, the fabric cutting assembly includes a second hydraulic cylinder 10 fixedly installed on the top of an L-shaped support plate 9. The output end of the second hydraulic cylinder 10 passes through the L-shaped support plate 9 and is fixedly connected to a cutter 26. Guide rods 11 are fixedly connected to the left and right sides of the top of the cutter 26. The top ends of the guide rods 11 pass through the L-shaped support plate 9 and are slidably connected to the L-shaped support plate 9. A protective groove 25 is provided on the top of the support platform 3 corresponding to the cutter 26. During operation, when the PLC controller 4 detects that the edge banding conveyor has reached the preset length, it will trigger... Hydraulic cylinder 210 is activated, and its output end extends downward, driving the cutter 26 to move steadily downward along the guide rod 21. The guide rod 211 ensures that the cutter 26 will not deviate during its downward movement, ensuring a clean cut. After the cutter 26 moves downward, it cuts the binding tape. The lower end of the cutter 26 extends into the protective groove 25 on the top of the support platform 3, preventing the cutter 26 from directly impacting the support platform 3 during cutting and causing damage to the cutter body. It also ensures that the binding tape is completely cut off. After the cutting is completed, hydraulic cylinder 210 drives the cutter 26 to reset, waiting for the next cutting command.

[0044] In a preferred embodiment of the present invention, the moving component includes an inner groove 32 formed on the left side inside the slot 27. A through-type heat dissipation groove 34 is formed on the lower surface of the inner groove 32. A second motor 33 is fixedly installed inside the inner groove 32. A threaded rod 28 is fixedly connected to the output end of the second motor 33. The right end of the threaded rod 28 is rotatably installed inside the right side of the slot 27. An internal threaded sleeve 29 is threadedly connected to the outer surface of the threaded rod 28. The top of the internal threaded sleeve 29 is fixedly connected to the U-shaped plate 5. During operation, when the clamping component clamps the edge of the mattress after the edging tape is sewn, the second motor 33 starts and drives the threaded rod 28 to rotate. After rotation, the internal threaded sleeve 29 moves linearly along the slot 27, thereby driving the U-shaped plate 5 and the mattress fixed by the clamping component to move synchronously and uniformly. This, combined with the edge binding tape delivered by the conveying component, enables continuous sewing, ensuring stable traction speed during mattress edge binding. This makes the edge binding tape delivery speed match the mattress movement speed, resulting in a smooth sewing process. Furthermore, the internal threaded sleeve 29 is rectangular and can slide stably inside the slot 27 by rotating the threaded rod 28. At the same time, the heat generated by the second motor 33 can be quickly dissipated to the outside through the heat dissipation groove 34 at the bottom of the inner groove 32, preventing the second motor 33 from overheating during prolonged operation and ensuring its continuous and stable operation.

[0045] In a preferred embodiment of the present invention, the clamping assembly includes a hydraulic cylinder 6 fixedly installed on the top of the U-shaped plate 5. The output end of the hydraulic cylinder 6 extends into the interior of the U-shaped plate 5 and is fixedly connected to a clamping plate 31. Guide rods 30 are fixedly connected to the four corners of the top of the clamping plate 31. The guide rods 30 penetrate the upper interior of the U-shaped plate 5 and are slidably connected to the U-shaped plate 5. During operation, after the mattress is adjusted to the correct position, the hydraulic cylinder 6 is activated, and its output end extends downward, driving the clamping plate 31 to move steadily downward along the guiding direction of the guide rods 30. The guide rods 30 ensure that the clamping plate 31 moves smoothly and without deviation during the downward movement, so that the clamping plate 31, together with the interior of the U-shaped plate 5, firmly clamps and fixes the part of the mattress that has been manually pulled and sewn. Then, the moving assembly pulls the subsequent edge stitching, and the moving assembly can drive the mattress to move at a uniform speed for sewing, thereby avoiding displacement of the mattress during the sewing process, ensuring the accuracy of the edge stitching, eliminating the need for manual pulling for edge stitching, and resulting in better sewing effect.

[0046] like Figure 9 As shown, a method for sewing mattress edging fabric to a fixed length using a mattress edging fabric cutting and sewing device of the aforementioned method includes the following steps:

[0047] S1. Place the rolled binding tape onto the vertical rod of the placement tray 7, then pull the end of the binding tape to pass through the conveying assembly and the guide assembly in sequence, and then place the end at the working position of the sewing machine body 2.

[0048] S2. Place the mattress to be edged on the placement platform 1, and sew the beginning part of one end of the mattress by manually pulling it. Then insert the sewn end into the U-shaped plate 5 and firmly clamp the end of the mattress by the clamping component.

[0049] S3, PLC controller 4 controls the conveying component to drive the binding tape to be continuously conveyed forward, and the rotary encoder 13 inside the conveying component synchronously records the number of rotations of the conveying roller 14, accurately calculates the conveying length of the binding tape, and then drives the U-shaped plate 5 and the mattress clamped and fixed to move at a uniform speed through the moving component, and in coordination with the conveying speed of the binding tape, the sewing machine body 2 continuously performs binding and sewing operations on the mattress.

[0050] S4. When the rotary encoder 13 detects that the conveying length of the binding tape has reached the preset value, it transmits the signal to the PLC controller 4. The PLC controller 4 controls the conveying component to stop conveying and controls the cutting component to cut the binding tape, thus completing the fixed-length cutting operation of the entire mattress floor.

[0051] Working principle: First, place the entire equipment stably on a flat ground. Load the rolled binding tape onto the vertical rod at the top of the placement tray 7. Then, pull the handle 18 to drive the pull rod 19, which pulls the slider 17 to compress the spring 21, creating space between the limiting roller 15 and the conveying roller 14. After pulling out the end of the binding tape, it passes through the space between the limiting roller 15 and the conveying roller 14 and between the two guide wheels 23 inside the guide plate 8, and is then pulled to the sewing position on the sewing machine body 2. Releasing the handle 18 resets the spring 21, pushing the limiting roller 15 to press the binding tape, completing the tape threading preparation. Then, place the mattress to be bound on the placement table 1 and manually sew one end of the mattress. Insert the sewn end into the U-shaped plate 5, and activate the hydraulic cylinder 6 to push the clamping plate 31 downwards, working with the U-shaped plate 5 to firmly clamp and fix the mattress end. Simultaneously, after starting work, the PLC controller 4... The control motor 12 starts and drives the conveyor roller 14 to rotate. The conveyor roller 14 drives the binding tape to continuously move forward. The rotary encoder 13 synchronously records the number of rotations of the conveyor roller 14 and accurately calculates the conveying length of the binding tape. At the same time, the control motor 23 starts and drives the threaded rod 28 to rotate. Through the internal threaded sleeve block 29, the U-shaped plate 5 and the mattress clamped and fixed move at a constant speed. With the conveying speed of the binding tape, the sewing machine body 2 continuously performs binding and sewing operations on the mattress. When the rotary encoder 13 detects that the conveying length of the binding tape has reached the preset value, it transmits the signal to the PLC controller 4. The PLC controller 4 controls the control motor 12 to stop conveying and triggers the hydraulic cylinder 210 to start and push the cutter 26 downward to cut the binding tape, completing the fixed-length cutting operation of the entire mattress. The whole process realizes fixed-length conveying, automatic cutting and continuous sewing of the binding tape, effectively improving the processing efficiency and processing accuracy of mattress binding.
