Description

Technical Field

[0001] This utility model relates to the field of mattress edge banding technology, and in particular to a mattress edge banding machine. Background Technology

[0002] In the mattress manufacturing process, edge sealing is a crucial step. It not only enhances the aesthetics of the mattress but also strengthens the edges and improves their durability.

[0003] Traditional mattress edge banding machines typically require manual flipping of mattresses that need double-sided edge banding. This not only increases labor intensity but can also damage the mattress due to improper operation. Some mattress edge banding machines with automatic flipping functions have poor stability during flipping, often causing the mattress to shake or bounce, which can easily damage the mattress. Therefore, we have proposed a mattress edge banding machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the increased labor intensity and potential damage to mattresses due to improper operation when manually flipping mattresses, as well as the poor stability of some mattress edge-sealing machines with automatic flipping functions. Therefore, this invention proposes a mattress edge-sealing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mattress edge banding machine includes a support base, a belt conveyor is installed inside the support base, an edge banding machine body is installed on one side of the support base, a positioning plate is fixedly installed on the top of the support base near the edge banding machine body, and a fixing plate is fixedly installed on the top of the support base away from the edge banding machine body. The fixing plate and the positioning plate are symmetrically arranged. Two slide rods slide through the fixing plate, and a moving plate is fixedly connected to one end of the two slide rods near the positioning plate. A cylinder is fixedly connected to one side of the fixing plate, and the output end of the cylinder passes through the fixing plate and is fixedly connected to one side of the moving plate.

[0007] The edge banding machine also includes:

[0008] The flipping assembly is located inside the support base and on one side of the belt conveyor, and is used to realize the automatic flipping of the mattress;

[0009] A limiting component is installed on the flipping component to cooperate with the flipping component to complete automatic flipping.

[0010] In one possible design, the flipping assembly includes a rotating frame, both sides of which are rotatably connected to the inner walls of the support base via rotating shafts. The rotating frame contains two sets of transmission rollers arranged vertically, each set consisting of multiple transmission rollers rotatably connected within the rotating frame. The distance between the two sets of transmission rollers is greater than the thickness of the mattress. A housing is fixedly mounted on one side of the rotating frame, and one end of each transmission roller penetrates the rotating frame and extends into the housing. A first motor is fixedly mounted on one side of the support base, and the output end of the first motor is fixedly connected to one of the rotating shafts. A drive assembly for driving the two sets of transmission rollers to rotate is located on one side of the rotating frame.

[0011] In one possible design, the drive assembly includes a plurality of first sprockets, which are respectively fixedly sleeved on corresponding transmission rollers, and all the first sprockets are located inside the housing. The same first chain is driven and connected to two adjacent first sprockets in the same transmission roller group. A second motor is fixedly installed on one side of the housing, and the output end of the second motor passes through the housing and is fixedly connected to one of the transmission rollers.

[0012] In one possible design, a second sprocket is fixedly mounted on one of the drive rollers in the upper drive roller group and one of the drive rollers in the lower drive roller group, and the two second sprockets are connected to the same second chain.

[0013] In one possible design, the limiting component includes a U-shaped frame, which is fixedly mounted at the bottom of the rotating frame. A groove is provided at the top of the U-shaped frame, and a movable rod is slidably connected within the groove. A limiting plate is fixedly mounted at the top end of the movable rod near the belt conveyor. The maximum thickness of the limiting plate is less than the distance between two adjacent drive rollers. The limiting plate passes through the bottom of the rotating frame and extends to the space between two corresponding adjacent drive rollers. Two positioning rods are symmetrically fixed at the bottom of the rotating frame, and both positioning rods pass through the movable rod and are slidably connected to it.

[0014] In one possible design, the bottom inner wall of the chute and the bottom of the rotating frame are rotatably connected by the same screw, the screw threaded through the moving rod, a third motor is fixedly installed at the bottom of the U-shaped frame, the output end of the third motor is fixedly connected to the screw, and multiple clamping components are fixedly installed at the top of the moving rod.

[0015] In one possible design, the clamping assembly includes a square tube, the bottom of which is fixedly connected to the top of a moving rod. A clamping block is slidably connected inside the square tube. Two limiting rods are symmetrically arranged on the bottom inner wall of the square tube, and both limiting rods are slidably inserted into the interior of the clamping block. A spring is sleeved on each of the two limiting rods. The top and bottom of the springs are fixedly connected to the bottom of the clamping block and the bottom inner wall of the square tube, respectively. The maximum thickness of the square tube and the clamping block is less than the distance between two adjacent drive rollers. The square tube and the clamping block both penetrate the bottom of the rotating frame and extend to the space between two corresponding adjacent drive rollers.

[0016] In this application, the mattress is first placed on a belt conveyor. During the conveying process of the belt conveyor, the edge sealing machine body located on one side seals the edge of the mattress. At this time, the positioning plate and the fixing plate play a positioning role for the mattress, so that the mattress is always close to one side of the edge sealing machine body during the edge sealing process, ensuring the accuracy of the edge sealing position.

[0017] When the mattress needs to be flipped, the belt conveyor starts in reverse, moving the mattress toward the flipping assembly. At the same time, the second motor starts, and the output of the second motor drives one of the drive rollers to rotate. Through the transmission action of the first sprocket and the first chain, and the second sprocket and the second chain, the drive rollers in the two sets of drive rollers rotate synchronously, so that the mattress moves into the interior of the rotating frame by rotating the lower drive roller set, waiting to be flipped.

[0018] Next, the third motor in the limiting assembly starts, and the output end of the third motor drives the screw to rotate, which in turn drives the moving rod to slide in the slide groove, thereby causing the limiting plate at the top of the moving rod to move upward in the rotating frame, thereby blocking and limiting one side of the mattress. At the same time, the pressing blocks in the multiple square tubes retract into the interior of the square tubes under the gravity of the mattress.

[0019] Then, the third motor stops working and the first motor starts. The output end of the first motor drives one of the rotating shafts to rotate, which in turn drives the rotating frame, the transmission roller group to rotate, and the mattress inside to rotate. During the process, due to the shift of the mattress's weight, the pressing blocks in multiple square tubes extend under the action of springs, thereby continuously squeezing one side of the mattress and reducing the phenomenon of the mattress shaking during the flipping process.

[0020] After the rotation is complete, the mattress falls onto the drive roller assembly that was originally located above. Finally, the third motor starts in reverse, which drives the limit plate and the pressing block away from the mattress. Then, the second motor starts and transports the flipped mattress to the belt conveyor for further edge sealing.

[0021] Beneficial effects: The mattress edge banding machine described in this utility model realizes automatic mattress flipping and limiting operations by setting a flipping component and a limiting component, which greatly improves the automation level and edge banding quality of mattress edge banding;

[0022] In this utility model, the mattress edge sealing machine adopts a rotating frame and transmission roller group design for the flipping component, which can not only realize the flipping operation of the mattress, but also automatically transport it after the flipping is completed, reducing the labor intensity of manual handling.

[0023] In this utility model, the mattress edge sealing machine, through the design of the limiting component, not only limits the position when the mattress is flipped, but also improves the stability of the mattress when flipping through the cooperation of the pressing block and the spring, thus avoiding shaking;

[0024] In this invention, by setting a flipping component and a limiting component, the automatic flipping and limiting operation of the mattress is realized, which improves the automation level and edge sealing quality of the mattress. The design of the rotating frame and transmission roller group not only realizes the flipping operation of the mattress, but also automatically transports it after the flipping is completed, reducing the labor intensity of manual handling. The limiting component not only limits the position of the mattress when flipping, but also improves the stability of the mattress when flipping through the cooperation of the pressing block and the spring.

The movable plate 6 is used to fix the position of the mattress in conjunction with the positioning plate 4.

[0034] A cylinder 8 is fixedly connected to one side of the fixed plate 5. The output end of the cylinder 8 passes through the fixed plate 5 and is fixedly connected to one side of the movable plate 6. The extension and retraction of the cylinder 8 can drive the movable plate 6 to slide on the slide rod 7, thereby achieving the clamping and releasing of the mattress.

[0035] The edge banding machine also includes a flipping assembly and a limiting assembly. The flipping assembly is located inside the support base 1 and on one side of the belt conveyor 2, and is used to automatically flip the mattress.

[0036] The flipping assembly includes a rotating frame 9, with both sides of the rotating frame 9 rotatably connected to the inner walls of both sides of the support base 1 via rotating shafts, allowing the rotating frame 9 to rotate around the rotating shafts. Inside the rotating frame 9 are two sets of drive rollers arranged vertically, each set consisting of multiple drive rollers 11 rotatably connected within the rotating frame 9.

[0040] The limiting component includes a U-shaped frame 16, which is fixedly mounted on the bottom of the rotating frame 9. A groove is provided on the top of the U-shaped frame 16, and a movable rod 17 is slidably connected in the groove. The movable rod 17 can slide in the groove to adjust the position of the limiting plate 18.

[0041] A limiting plate 18 is fixedly installed at the top of the moving rod 17 near the belt conveyor 2. The maximum thickness of the limiting plate 18 is less than the distance between two adjacent drive rollers 11, ensuring that the limiting plate 18 can pass smoothly between the drive rollers 11. The limiting plate 18 passes through the bottom of the rotating frame 9 and extends to the space between two corresponding adjacent drive rollers 11, for limiting the position of the mattress.

[0042] The bottom inner wall of the chute and the bottom of the rotating frame 9 are rotatably connected by the same screw 19. The screw 19 is threaded through the moving rod 17. By rotating the screw 19, the moving rod 17 can be driven to slide in the chute, thereby adjusting the position of the limiting plate 18.

[0043] A third motor 20 is fixedly installed at the bottom of the U-shaped frame 16. The output end of the third motor 20 is fixedly connected to the screw 19. The screw 19 can be rotated by the drive of the third motor 20, thereby realizing the automatic adjustment of the moving rod 17.

[0044] Multiple clamping components are fixedly installed at the top of the moving rod 17 to clamp the mattress, preventing violent shaking when the mattress is turned over. The clamping components include a square tube 22, the bottom of which is fixedly connected to the top of the moving rod 17. A clamping block 23 is slidably connected inside the square tube 22, allowing it to slide within the tube to accommodate mattresses of different thicknesses. Two limiting rods are symmetrically arranged on the bottom inner wall of the square tube 22, both slidingly inserted into the clamping block 23 to limit its movement and prevent it from detaching from the tube 22. Springs 24 are fitted onto both limiting rods, with their tops and bottoms fixedly connected to the bottom of the clamping block 23 and the bottom inner wall of the square tube 22, respectively. The elastic force of the springs 24 ensures that the clamping block 23 remains in close contact with the mattress.

[0045] The maximum thickness of the square tube 22 and the pressing block 23 is less than the distance between two adjacent drive rollers 11, ensuring that the square tube 22 and the pressing block 23 can pass smoothly between the drive rollers 11. Both the square tube 22 and the pressing block 23 pass through the bottom of the rotating frame 9 and extend to the space between two adjacent drive rollers 11 for pressing the mattress.
