Detailed Implementation

[0031] Please see Figure 1-9This utility model provides a technical solution: an edge-folding mechanism for an edge-binding machine, including a frame assembly 1, which is composed of multiple frames forming a frame assembly. A first suction mechanism 2 is installed at the top of the frame assembly 1, a first edge-folding mechanism 3 is installed on one side of the first suction mechanism 2, and a second edge-folding mechanism 4 is installed on one side of the first edge-folding mechanism 3. The first edge-folding mechanism 3 includes a first placement bed 31, and second guide rails 12 are installed at both ends of the first placement bed 31. The first placement bed 31 has several through holes for air circulation on its surface. Edge-folding components 32 are installed on both sides of the first placement bed 31, and second connecting plates 33 are fixedly connected to both ends of the edge-folding components 32. The second connecting plates 33 transmit... The first placement bed 31 is connected to a third drive assembly 34. An air extraction groove 35 is installed between the two third drive assemblies 34 and is located below the through hole in the first placement bed 31. The air extraction groove 35 is connected to a second air pump for extracting air from the surface of the first placement bed 31. The folding assembly 32 includes a first fixing plate 321. Both ends of the first fixing plate 321 are connected to a second guide rail via slides. A first folding plate 322 for folding the cardboard is installed at the bottom of the first fixing plate 321. Fourth drive mechanisms 323 are installed on both sides of the top of the first fixing plate 321. The two fourth drive mechanisms are respectively connected to folding blocks 324. The first folding plate 322 has an adjustment groove 3221 for adjusting the movement of the folding blocks. A first spring 325 is installed between plate 321 and the first folding plate 322. The bottom end of the folding block 324 passes through the adjusting groove 3221 and is equipped with a corner pressing piece 3241 for pressing the corner during the folding process. First guide rails are installed on both sides of the frame assembly 1. The top ends of the two first guide rails are connected to the first movable components via sliders. The first movable components are drivenly connected to the second drive assembly 28. A second suction mechanism 5 is installed at the top of the second folding mechanism 4. A shielding assembly 6 is installed on the frame assembly 1 above the first suction mechanism 2. The shielding assembly 6 is composed of multiple shields. A fourth guide rail is provided at the top of the frame assembly 1. The second suction mechanism 5 includes a sixth drive assembly 51, which is installed on the frame assembly 1. The two sides of the frame assembly 1 are provided with two fifth drive components, each of which is connected to a third connection plate 43. A second fixed plate 44 is provided between the two sixth drive components 51 and a second folding plate 45 is provided at the bottom of the frame assembly 1. The frame assembly 1 is provided with two fifth drive components, each of which is connected to a third connection plate 43. A second fixed plate 44 is provided between the two third connection plates 43. A second folding plate 45 is provided at the bottom of the second fixed plate 44. A second spring is provided between the second fixed plate 44 and the second folding plate 45.

[0032] The fifth drive assembly is used in conjunction with the third connecting plate 43. The fifth drive assembly is located between the second fixed plate 44 and the first placement bed 31. The fifth drive assembly consists of a screw, a nut, a motor, a track, a belt, and a pulley. The motor drives the belt to drive the pulley to rotate, and the pulley drives the screw to rotate. The screw rotates along the nut. The threads on the inner wall of the nut and the threads on the outer wall of the screw generate a mechanical transmission driving force. The screw drives the nut by relying on the threads. The third connecting plate 43 corresponding to the nut slides back and forth along the surface of the second placement bed 41. The third connecting plate 43 allows the second suction mechanism 5 to move back and forth along the second placement bed 41. The fifth drive assembly adopts a structure design of motor, track, belt, and pulley, which is stable and reliable in transmission, has high power transmission efficiency, and is easy to maintain and replace parts, thus extending the service life of the equipment.

[0033] The working principle and structure of the first active component, the folding component 32, and the third driving component 34 are consistent with those of the fifth driving component, so the working principle and structure of the first active component, the folding component 32, and the third driving component 34 will not be described again.

[0034] The sixth drive assembly 51 and the second drive assembly 28 consist of an electric motor and a conveyor belt, which facilitates the transfer of cardboard from the US production line to the mechanism, thereby achieving automatic feeding of the edge banding machine.

[0035] After the cardboard is conveyed from the assembly line to the first placement bed 31, the folding assembly 32 moves onto the cardboard. As the cardboard moves with the second suction mechanism 5, it moves to the corresponding position. The spring 325 presses and fixes the cardboard onto the first placement bed 31. The folding assembly 32 will deform the cardboard during the movement. The corner pressing member 3241 makes the cardboard warp and presses the corner of the cardboard to facilitate the folding and corner pressing operation of the cardboard.

[0036] After the cardboard is folded and the corners are pressed, the second suction mechanism 5 picks up the folded and cornered cardboard. The second suction mechanism 5 has multiple built-in suction cups that can hold the cardboard. The second suction mechanism 5 moves the cardboard from the first placement bed 31 to the second placement bed 41. The cardboard comes into contact with the second suction mechanism 5, and the second suction mechanism 5 squeezes the two ends of the cardboard to fold the two ends. After the two ends of the cardboard are folded, the second suction mechanism 5 moves the suction cups upward to release the cardboard.

[0037] The cardboard that needs edge binding is conveyed to the area below the monitoring camera module 63 via the conveyor belt 21. After the monitoring camera module 63 monitors the orientation of the cardboard, the two second drive components 28 operate, and the two first movable components move along the X-axis, driving the first suction claw assembly 27 to adjust to the same orientation as the cardboard. The first lifting mechanism 26 operates, and after the first suction claw assembly 27 moves downward to pick up the cardboard, the first lifting mechanism 26 operates again, and the first suction claw assembly 27 moves upward. The two second drive components 28 operate, and the two first movable components move to a position parallel to the central axis of the conveyor belt 21, thereby realizing the cardboard alignment. The first drive component 25 rotates, enabling the first suction claw assembly 27 to move along the Y-axis.

[0038] The first suction component 2 operates in conjunction with the cardboard with the edge-sealing paper attached, placing it above the first folding plate 322. The third drive component 34 operates, and the second connecting plate 33 drives the folding component 32 to move along the second guide rail, thereby realizing the folding activity of this utility model. During the folding operation, the corner pressing component 3241 flattens the folded corner, thereby realizing that the folding and corner pressing operations of this utility model are carried out simultaneously. The fourth drive mechanism 323 operates to adjust the distance between the two folding blocks 324, thereby enabling this utility model to be applicable to the corner pressing operation of cardboard of different specifications.

[0039] The sixth drive assembly 51 operates, and the fourth connecting plate 52 drives the first movable plate 53 to move along the fourth guide rail to above the first placement bed 31. The second lifting mechanism 54 moves up and down, thereby enabling the second suction claw group 55 to pick up the cardboard after the two sides have been folded. The sixth drive assembly 51 operates again, and the fourth connecting plate 52 drives the first movable plate 53 to move along the fourth guide rail to above the second placement bed 41, and then places the unfolded cardboard on both sides above the second folding plate 45. The fifth drive assembly operates, and the third connecting plate 43 drives the second folding plate 45 to achieve the folding action.

[0040] The first suction mechanism 2 and the second suction mechanism 5 mounted on the top of the second folding mechanism 4, respectively, can quickly and stably pick up the cardboard to be folded, reducing manual intervention and improving work efficiency. The first guide rails on both sides of the frame assembly 1, together with the slider and the second drive assembly 28, drive the first movable component to achieve accurate transfer of the cardboard between the mechanisms and ensure the continuity of the processing flow.

[0041] The first placement bed 31 of the first folding mechanism 3 has a through hole and cooperates with the second air pump and the air extraction groove 35 to firmly adhere the cardboard to the surface of the first placement bed 31, preventing the cardboard from shifting during the folding process and ensuring folding accuracy. In the folding assembly 32, the first fixing plate 321 is connected to the second guide rail 12 through a slide, which facilitates flexible position adjustment; the first folding plate 322, together with the folding block 324, the corner pressing piece 3241, and the elastic buffer of the first spring 325, can adapt to cardboard of different thicknesses and materials, achieve multi-angle, high-quality folding, and reduce damage to the cardboard during the folding process.

[0042] The orderly arrangement of the first folding mechanism 3 and the second folding mechanism 4 forms a multi-stage folding process, which can perform step-by-step and accurate folding of cardboard, meet the needs of complex edge-wrapping processes, and improve edge-wrapping quality and yield. In the second folding mechanism 4, the third guide rail 42 and the fifth drive assembly on both sides of the second placement bed 41, together with the third connecting plate 43, the second fixing plate 44 and the second folding plate 45, work in conjunction with the first folding mechanism 3 to further enhance the folding effect.

[0043] The shield assembly 6, located above the first suction mechanism 2, in the frame assembly 1, effectively prevents debris from flying during processing, ensuring operator safety. The second suction mechanism 5, through the combination of the sixth drive assembly 51, the fourth connecting plate 52, the first movable plate 53, the second lifting mechanism 54, and the second suction claw assembly 55, achieves flexible suction and placement action control, and can be accurately adjusted according to different working conditions, improving equipment applicability.

[0044] Through reasonable connection and transmission design between components, such as the buffering effect of springs, hard collisions and wear between components are reduced, further improving the stability and durability of the entire folding mechanism.
