[0010] Preferably, a metal detection bar is installed between the conveying rollers near the feeding position, and a weighing sensor is installed inside the defective material waiting platform.

[0011] Preferably, both ends of the frame are provided with end face centering plates, and the inner sides of both ends of the frame are equipped with second lifting cylinders, the output ends of the second lifting cylinders are connected to the end face centering plates in a transmission manner. Two Y-axis transmission belt mechanisms are installed between the two reinforcing rods, and the two ends of the two Y-axis transmission belt mechanisms are connected by a first synchronous shaft in a transmission manner. A Y-axis transmission motor assembly is installed at the end of one end of the first synchronous shaft, and the Y-axis transmission motor assembly is fixedly connected to the reinforcing rod. A Y-axis guide rail is installed between the two support frames, and the second lifting cylinder is slidably connected to the Y-axis guide rail through a Y-axis slide table, and the side of the Y-axis slide table is connected to the Y-axis transmission belt mechanism in a transmission manner.

[0012] Preferably, two X-axis drive belt mechanisms are installed between the two frames. The ends of the two X-axis drive belt mechanisms are connected by a second synchronous shaft. An X-axis drive motor assembly is driven and connected to one end of the second synchronous shaft. The X-axis drive motor assembly is fixedly connected to the frame by a mounting component. X-axis guide rails are provided on the outer sides of the two X-axis drive belt mechanisms. The two ends of the X-axis guide rails are fixedly connected to the two frames. An X-axis slide is slidably connected to the X-axis guide rail. The side of the X-axis slide is driven and connected to the X-axis drive belt mechanism. A transmission frame is installed above the X-axis slide. The upper end of the transmission frame extends outward along the gap of the conveyor rollers and is equipped with a side centering plate.

[0013] Preferably, a transverse guide wheel mechanism is provided between adjacent conveying rollers, and multiple transverse guide wheel mechanisms are provided. A lifting frame is installed below the transverse guide wheel mechanism, and a first lifting cylinder is installed below the lifting frame. The output end of the first lifting cylinder is connected to the lifting frame in a transmission manner, and the first lifting cylinder is connected to the reinforcing rod through a cylinder carrier plate.

[0014] Preferably, the lower surface of the side center plate is provided with several anti-wear blocks.

[0015] Preferably, a production process for a double-sided composite production line for flip-type mattress fabric includes the following steps:

[0016] Step 1: The bed core material first enters the first production section and is centered along the X-axis by the automatic centering table at the front end. During centering, the first lifting cylinder is driven to move, causing the transverse guide wheel mechanism between the conveyor rollers to move upward, so that the transverse guide wheel mechanism contacts the bottom surface of the bed core material. After contact, the X-axis drive motor assembly runs, driving the X-axis drive belt mechanism. Because the side centering plates on both sides are connected to the upper and lower edges of the X-axis drive belt mechanism through the X-axis slides respectively, the X-axis drive belt mechanism can drive the two sets of side centering plates. The middle plate moves in opposite directions to center the core material along the X-axis. After centering, the transverse guide wheel mechanism and the side centering plate are reset. The roller drive motor of the automatic centering platform runs, driving the core material to move to the glue spraying belt. When the core material passes through the automatic centering platform, the metal detection rod located in the automatic centering platform detects the core material. If a metal foreign object is detected, it is judged to be a defective product and a signal is fed back to the controller system. The subsequent glue spraying process is skipped directly, and the material is sent to the industrial robotic arm to be picked up and placed on the defective material waiting table.

[0017] Step 2: After the qualified material arrives at the glue spraying conveyor, the automatic glue spraying machine uses high-pressure air to atomize and spray the glue onto the material surface to achieve uniform glue distribution;

[0018] Step 3: After the adhesive is sprayed, the material is further conveyed to the front-end automatic centering platform. After the automatic centering platform performs X-axis centering on the material, the transverse guide wheel mechanism is reset, and the side centering plate remains in the limit state. At this time, the second lifting cylinder runs, driving the end face centering plates at both ends of the automatic centering platform to move up. Then the Y-axis drive motor assembly runs, driving the Y-axis drive belt mechanism to drive the end face centering plates to move in opposite directions, and simultaneously perform Y-axis centering on the bed core material to achieve four-way centering positioning.

[0019] Step 4: During the four-way centering process, the column-type robotic arm uses the filler material disassembly tool at the output end to grab the material to be composited from the filler material waiting platform and place it on the upper waiting platform of the composite platform. Meanwhile, the CCD camera continuously monitors the four-way centering process. After centering is completed, a signal is sent to the controller system to drive the industrial robotic arm to run. The industrial robotic arm uses the filler material composite tool to grab the material to be composited that is pre-placed on the upper waiting platform and composites it on the front of the bed core on the four-way center platform. After the composite is completed, it is transferred to the belt conveyor through the lower layer of the composite platform.

[0020] Step 5: The belt conveyor transports the composite material to the tilting press, where it is received by the lower belt conveyor. After completion, the scissor lifts located at the lower and upper ends of the tilting press are driven synchronously, causing the lower and upper belt conveyors to move in opposite directions to clamp and fix the core material. By squeezing the fabric, a strong bond is ensured. During the clamping process, the tilting drive motor runs, and through the meshing of gears and transmission belts, it drives the transmission belt to drive the annular grooves on both sides of the tilting frame, causing the tilting frame to rotate 180° and switch the positions of the upper and lower belt conveyors. After the tilting is completed, the scissor lifts are reset, and the original upper belt conveyor transfers the flipped core material to the second production section.

[0021] Step Six: The second production section repeats the processing of the first production section, performing composite treatment on the reverse side of the bed core material;

[0022] Step 7: The double-sided composite mattress material continues to be transferred to the subsequent processing point, where the work of attaching the bedding strips is completed manually;

[0023] Step 8: Each section of the production line is equipped with a metal detection rod to detect iron impurities and perform a qualification test on the bed core. If it passes the test, it flows into the next process; if it fails, it is transferred to the defective material waiting table. The defective material waiting table has a built-in weighing sensor. If the stacked defective material reaches the threshold, the weighing sensor will send a feedback signal to the terminal alarm, which will sound an alarm and remind personnel to transfer the defective material to the centralized recycling point by forklift.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] (1) The present invention sets up a flipping press between the first and second production sections that are connected end to end. After the first production section has completed the front-side lamination of the mattress core material, it can transition to the flipping press. The flipping press uses a scissor lift to drive the upper and lower belt conveyors to clamp the material in opposite directions. The hydraulic cylinder squeeze ensures the bonding strength. The gear meshing drive belt drives the flipping frame to rotate, completes the flipping of the material and transfers it to the second production section. Thus, the second production section is used to perform lamination processing on the back side of the mattress core material. This realizes the continuous completion of double-sided lamination on a single production line, greatly improves production efficiency, and solves the problem that the existing mattress lamination production line can only realize single-sided lamination processing of mattresses and is not suitable for double-sided lamination scenarios.

[0026] (2) This invention uses an automatic centering stage at the composite processing position, and the automatic centering stage adopts XY axis linkage centering technology:

[0027] X-axis centering: The first lifting cylinder drives the transverse guide wheel mechanism to lift the material, and the X-axis transmission belt drives the side centering plate to clamp it in opposite directions.

[0028] Y-axis centering: The end face centering plate is lifted by the second lifting cylinder, and the Y-axis transmission belt drives the two end centering plates to clamp synchronously.

[0029] Based on the high precision of four-way centering, the composite layer is aligned without deviation, significantly improving the product yield.

[0030] (3) The present invention has full-process metal detection. Each automatic centering platform has a built-in metal detection rod to scan iron impurities in real time. It also has an automatic sorting function for defective products. When the detection is abnormal, the industrial robotic arm can grab the material to the defective material waiting platform. The defective material waiting platform has a built-in weighing sensor. If the stack is too heavy, it will trigger a terminal alarm and be transferred and recycled by a forklift to avoid defective products from flowing into subsequent processes.

Several anti-wear blocks 306 are provided on the lower surface of the side centering plate 305. The anti-wear blocks 306 are made of flexible material, which can prevent the lower end of the side centering plate 305 from wearing when it moves laterally.

[0045] Please see Figure 1-9 A production process for a double-sided composite production line of flip-up mattress fabric includes the following steps:

[0046] Step 1: The bed core material first enters the first production section 1, where it is centered along the X-axis by the automatic centering table 3 at the front end. During centering, the first lifting cylinder 313 is driven to move, causing the transverse guide wheel mechanism 304 between the conveying rollers 303 to move upward, so that the transverse guide wheel mechanism 304 contacts the bottom surface of the bed core material. After contact, the X-axis drive motor assembly 319 runs, driving the X-axis drive belt mechanism 321. Because the side centering plates 305 on both sides are connected to the upper and lower edges of the X-axis drive belt mechanism 321 respectively through the X-axis slide table 323, they can drive the bed core material under the transmission action of the X-axis drive belt mechanism 321. Two sets of side centering plates 305 move in opposite directions to center the bed core material along the X-axis. After the X-axis centering, the transverse guide wheel mechanism 304 and the side centering plates 305 are reset. The roller drive motor 324 of the automatic centering platform 3 runs, driving the bed core material to the glue spraying belt 4. When the bed core material passes through the automatic centering platform 3, the metal detection rod 327 located in the automatic centering platform 3 detects the bed core material. If a metal foreign object is detected, it is judged to be a defective product and a signal is fed back to the controller system. The subsequent glue spraying process is skipped directly, and the material is sent to the industrial robotic arm 7 to grab and place it on the defective material waiting platform 13.

[0047] Step 2: After the qualified material arrives at the glue spraying conveyor belt 4, the automatic glue spraying machine 5 sprays the glue onto the material surface by atomizing it with high-pressure air to achieve uniform glue distribution.

[0048] Step 3: After the adhesive is sprayed, the material is further conveyed to the front-end automatic centering platform 3. After the automatic centering platform 3 performs X-axis centering on the material, the transverse guide wheel mechanism 304 is reset, and the side centering plate 305 remains in the limit state. At this time, the second lifting cylinder 315 runs, driving the end face centering plates 314 at both ends of the automatic centering platform 3 to move upward. Then, the Y-axis drive motor assembly 318 runs, driving the Y-axis drive belt mechanism 316 to drive the end face centering plates 314 to move in opposite directions, and simultaneously centering the Y-axis of the bed core material to achieve four-way centering positioning.

[0049] Step 4: During the four-way centering process, the column-type robotic arm 11 uses the filler material disassembly tool at the output end to grab the material to be composited from the filler material waiting platform 12 and place it on the upper waiting platform 8 of the composite platform 6. Meanwhile, the CCD camera (not shown in the figure) continuously monitors the four-way centering process. After centering is completed, a signal is sent to the controller system to drive the industrial robotic arm 7 to run. The industrial robotic arm 7 uses the filler material composite tool to grab the material to be composited pre-placed on the upper waiting platform 8 and composite it on the front of the bed core on the four-way centering platform. After the composite is completed, it is transferred to the belt conveyor 10 through the lower layer of the composite platform 6. (Note: If special processes or special orders require manual completion, after the glue spraying machine finishes spraying glue, it directly passes through the four-way centering platform and the lower layer of the composite platform, and then to the belt conveyor composite platform, where the corresponding process is completed manually, and then the conveyor pipe is used to reach the automatic centering platform of the second production section.)

[0050] Step 5: The belt conveyor 10 transports the composite material to the tilting press 14, where it is received by the lower belt conveyor 145. After completion, the scissor lifts 144 located at the lower and upper ends of the tilting press 14 are synchronously driven, causing the lower belt conveyor 145 and the upper-lower belt conveyor 145 to move in opposite directions to clamp and fix the bed core material. By squeezing the fabric, the adhesion is ensured. During the clamping process, the tilting drive motor 1472 runs, and through the meshing of the gear 1473 and the transmission belt 148, the transmission belt 148 drives the transmission belt 148 to drive the annular grooves 146 on both sides of the tilting frame 142, causing the tilting frame 142 to rotate 180° and switch the positions of the upper and lower belt conveyors 145. After the tilting is completed, the scissor lift 144 is reset, and the original upper belt conveyor 145 transfers the flipped bed core material to the second production section 2.

[0051] Step Six: The second production section 2 repeats the processing of the first production section 1, and performs composite processing on the reverse side of the bed core material;

[0052] Step 7: The double-sided composite mattress material continues to be transferred to the subsequent processing point, where the work of attaching the bedding strips is completed manually;

[0053] Step 8: Each section of the production line is equipped with a metal detection rod 327 to detect iron impurities and perform a qualification test on the bed core. If it passes the test, it flows into the next process; if it fails, it is transferred to the defective material waiting table 13. The defective material waiting table 13 has a built-in weighing sensor. If the stacked defective material reaches the threshold, the weighing sensor will send a feedback signal to the terminal alarm, which will sound an alarm and remind personnel to transfer the defective material to the centralized recycling point by forklift.

10. A production process for a double-sided composite production line for flip-type mattress fabric, implemented based on the double-sided composite production line for flip-type mattress fabric described in claim 9, characterized in that... Includes the following steps: Step 1: The bed core material first enters the first production section (1), and is centered along the X-axis by the front-end automatic centering table (3). During centering, the first lifting cylinder (313) is driven to run, which drives the transverse guide wheel mechanism (304) between the conveying rollers (303) to move upward, so that the transverse guide wheel mechanism (304) contacts the bottom surface of the bed core material. After contact, the X-axis drive motor assembly (319) runs, driving the X-axis drive belt mechanism (321) to drive. Since the side centering plates (305) on both sides are connected to the upper and lower edges of the X-axis drive belt mechanism (321) through the X-axis slide (323) respectively, they can carry the material under the transmission action of the X-axis drive belt mechanism (321). The two sets of side centering plates (305) move in opposite directions to center the bed core material on the X-axis. After the X-axis is centered, the transverse guide wheel mechanism (304) and the side centering plate (305) are reset. The roller drive motor (324) of the automatic centering platform (3) runs, driving the bed core material to the glue spraying belt (4). When the bed core material passes through the automatic centering platform (3), the metal detection rod (327) located in the automatic centering platform (3) detects the bed core material. If a metal foreign object is detected, it is judged to be a defective product and a signal is fed back to the controller system. The subsequent glue spraying process is skipped directly, and the material is sent to the industrial robotic arm (7) to grab and place it on the defective material waiting platform (13). Step 2: After the qualified material arrives at the glue spraying conveyor belt (4), the automatic glue spraying machine (5) sprays the glue onto the material surface by atomizing it with high-pressure air to achieve uniform glue distribution; Step 3: After the material is sprayed with glue, it is further transported to the front automatic centering platform (3). After the automatic centering platform (3) performs X-axis centering on the material, the transverse guide wheel mechanism (304) is reset and the side centering plate (305) remains in the limit state. At this time, the second lifting cylinder (315) runs, driving the end face centering plates (314) at both ends of the automatic centering platform (3) to move upward. Then the Y-axis drive motor assembly (318) runs, driving the Y-axis drive belt mechanism (316) to drive the end face centering plates (314) to move in opposite directions, and the Y-axis of the bed core material is simultaneously centered to achieve four-way centering positioning. Step 4: During the four-way centering process, the column-type robotic arm (11) uses the filler disassembly tool at the output end to grab the material to be composited from the filler waiting platform (12) and place it on the upper waiting platform (8) of the composite platform (6). The CCD camera continuously monitors the four-way centering process during this process. After centering is completed, a signal is fed back to the controller system to drive the industrial robotic arm (7) to run. The industrial robotic arm (7) uses the filler composite tool to grab the material to be composited that is pre-placed on the upper waiting platform (8) and composites it on the front of the bed core on the four-way center platform. After the composite is completed, it is transferred to the belt conveyor (10) through the lower layer of the composite platform (6). Step 5: The belt conveyor (10) transports the composite material to the tilting press (14), where it is received by the lower belt conveyor (145). After completion, the scissor lifts (144) located at the lower and upper ends of the tilting press (14) are synchronously driven, causing the lower belt conveyor (145) and the upper-lower belt conveyor (145) to move in opposite directions to clamp and fix the core material. By squeezing the fabric, the adhesion is ensured to be firm. During the clamping process, the material is tilted... The drive motor (1472) runs, and through the meshing of the gear (1473) and the transmission belt (148), the transmission belt (148) drives the annular grooves (146) on both sides of the flipping frame (142) to rotate the flipping frame (142) 180°, and the positions of the upper and lower belt conveyors (145) are changed. After the flipping is completed, the scissor lift (144) is reset, and the original upper belt conveyor (145) transfers the flipped bed core material to the second production section (2). Step 6: The second production section (2) repeats the processing of the first production section (1) to perform composite treatment on the reverse side of the bed core material; Step 7: The double-sided composite mattress material continues to be transferred to the subsequent processing point, where the work of attaching the bedding strips is completed manually; Step 8: Each section of the production line is equipped with a metal detection bar (327) to detect iron impurities and perform a qualification test on the bed core. If it is qualified, it flows into the next process; if it is unqualified, it is transferred to the defective material waiting table (13). The defective material waiting table (13) is equipped with a built-in weighing sensor. If the stacked defective materials reach the threshold, the weighing sensor will send a feedback signal to the terminal alarm, which will sound an alarm and remind personnel to transfer the defective materials to the centralized recycling point by forklift.
