Detailed implementation mode

[0028] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0029] As Figure 1-11 shown, a full-automatic intelligent integrated machine for cutting and sticking sealing strips includes a support 1, a loading rack, a limiting mechanism, a cutting mechanism and a bonding mechanism. The loading rack is arranged on one side of the support 1. The limiting mechanism is arranged between the loading rack and the support 1. The cutting mechanism and the bonding mechanism are both arranged on the support 1;

[0030] The limiting mechanism includes a limit motor 8, a first roller unit and a second roller unit. The first roller unit includes a first driving unit, two first rollers 4 and one second roller 5. The two first rollers 4 are arranged horizontally side by side. The second roller 5 is located in the middle above the two first rollers 4. The first driving unit drives the first rollers 4 to move up and down. The second roller unit includes a third roller 6 and a fourth roller 7. The third roller 6 is located directly above the fourth roller 7. The limit motor 8 drives the fourth roller 7 to rotate. The first driving unit drives the third roller 6 to move up and down;

[0031] During loading, the rubber strip passes through the gaps between the first roller 4 and the second roller 5 and between the third roller 6 and the fourth roller 7. The gaps here are set according to the height of the rubber strip. Since the cross-section of the rubber strip is actually square, such height-limited transmission can prevent the rubber strip from deflecting and twisting. The limit motor 8 drives the fourth roller 7 to rotate, and drives the rubber strip to be conveyed to the subsequent process by relying on friction. The cooperation between the turntable 10 and the first screw 9 is to make the connecting plate lift, so as to adjust the heights of the second roller 5 and the third roller 6. In fact, the heights of the first roller 4 and the fourth roller 7 are equal, which is convenient for synchronous adjustment, reduces the adjustment steps, and improves the convenience of adjustment.

[0032] The cutting mechanism includes a transmission unit, a pressing plate 11, a blade, and a first cylinder 12. The first cylinder 12 is vertically downward, the blade is vertically arranged at the top of the air rod of the first cylinder 12, the pressing plate 11 is arranged on one side of the blade, the pressing plate 11 is in contact with the blade. The transmission unit includes a transmission motor 13, a second screw rod 14, a slide rail 15, a first clamping unit, and a second clamping unit. The first clamping unit and the second clamping unit are respectively located on both sides of the pressing plate 11. The second clamping unit is located between the limiting mechanism and the pressing plate 11. The first clamping unit is arranged on the slide rail 15. The second screw rod 14 is installed on the transmission motor 13. The transmission motor 13 drives the first clamping unit to move on the slide rail 15 through the second screw rod 14. The first clamping unit and the second clamping unit are connected by a connecting rod 21;

[0033] Here, the overall transmission of the rubber strip is actually achieved through the synchronous movement of the first clamping unit and the second unit. That is, under the connection action of the connecting rod, the first clamping unit and the second unit hold both ends of the rubber strip and move under the pressing plate 11. Compared with pulling the rubber strip at one end in the prior art, the rubber strip can maintain a better shape and prevent being overstretched, which affects the quality of the finished product.

[0034] The bonding mechanism includes a material clamping assembly and a bonding assembly;

[0035] The material clamping assembly includes a second driving unit and two clamping arms 16. The two clamping arms 16 are arranged side by side on one side of the pressing plate 11. The second driving unit drives the two clamping arms 16 to move and rotate. A number of through holes are provided on the pressing plate 11. The through holes are arranged horizontally side by side in a row. The two clamping arms 16 are located on one side of the through holes. The straight line where each through hole is located is parallel to the clamping arms 16;

[0036] The second driving unit here is actually a combination of a cylinder and a motor, used to drive the clamping arm 16 to be able to achieve three-dimensional multi-directional movement and to be able to achieve the clamping function. Here, it belongs to conventional driving and transmission components, so it is not described in detail. As long as the above functions can be achieved.

[0037] The bonding assembly includes a glue application unit, a turntable, and a number of bonding units. The glue application unit includes a glue application plate 17 and a conduit 18. The glue application plate 17 is parallel to the pressing plate 11 and is located above the side of the pressing plate 11 close to the first clamping unit. One end of the conduit 18 is connected to the glue application plate 17. The turntable is arranged on one side of the pressing plate 11, and the bonding units are circumferentially and evenly arranged on the outer periphery of the turntable. The turntable drives the bonding units to rotate. The bonding unit includes an upper heating plate 19 and a lower heating plate 20. The upper heating plate 19 is arranged directly above the lower heating plate 20. Both the upper heating plate 19 and the lower heating plate 20 are located between the two clamping arms 16. The lower end of the upper heating plate 19 and the upper end of the lower heating plate 20 are both provided with serrated openings, and the serrated openings of the upper heating plate 19 are arranged opposite to the serrated openings of the lower heating plate 20. Both the upper heating plate 19 and the lower heating plate 20 are driven to move by cylinders.

[0038] Preferably, the loading rack includes a frame 2, guide rollers 3, and a conduction unit. The guide rollers 3 are horizontally arranged on the frame 2. The conduction unit includes a guide plate 28, and a number of through holes are provided on the guide plate 28. The through holes are arranged horizontally side by side in a row, and the axes of the through holes are in the same horizontal plane as the axis of the perforation.

[0039] During loading, the rubber strip is wound around the guide roller 3, then passed through the through holes of the guide plate 28, and then input into the subsequent process.

[0040] Preferably, the first driving unit includes a connecting plate, a first screw rod 9, and a turntable 10. The connecting plate is respectively connected to the second roller 5 and the third roller 6. The first screw rod 9 passes through the connecting plate and is threadedly connected to the connecting plate. The turntable 10 is installed on the first screw rod 9.

[0041] Preferably, the first clamping unit includes an upper clamping plate 22, a lower clamping plate 23, and a second cylinder 24. The lower clamping plate 23 is slidably connected to the slide rail 15. The upper clamping plate 22 is located directly above the lower clamping plate 23. The second cylinder 24 is arranged vertically downward, and the upper clamping plate 22 is arranged at the top of the air rod of the second cylinder 24.

[0042] Preferably, the second clamping unit includes an upper pressing plate 25, a lower pressing plate 26, and a third cylinder 27. The lower pressing plate 26 is arranged on the bracket 1. The upper pressing plate 25 is located directly above the lower pressing plate 26. The third cylinder 27 is arranged vertically downward, and the upper pressing plate 25 is arranged at the top of the air rod of the third cylinder 27. The two ends of the connecting rod 21 are respectively connected to the lower clamping plate 23 and the lower pressing plate 26.

[0043] The rubber strip first bypasses the guide roller 3, passes through the guide plate 28 and then enters between the first roller unit and the second roller unit of the limiting unit. Driven by the limiting motor 8, it enters between the upper pressing plate 25 and the lower pressing plate 26 of the second clamping unit. At this time, the second cylinder 24 is in a contracted state. Then it passes through the pressing plate 11. The driving motor 13 rotates to drive the second screw rod 14 to rotate. Driven by the second screw rod 14, the first clamping unit moves on the slide rail 15 towards the direction close to the pressing plate 11, so that the end of the rubber strip is exactly located between the upper clamping plate 22 and the lower clamping plate 23 of the first clamping unit. Then the second cylinder 24 and the third cylinder 27 act simultaneously. The first clamping unit clamps the end of the rubber strip, and the second clamping unit clamps a certain position in the middle of the rubber strip. Then the driving motor 13 reverses a certain number of turns, so that the first clamping unit moves away from the pressing plate 11, and the moving distance is the length of the rubber strip pulled out from the other side of the pressing plate 11. Then the first cylinder 12 acts to drive the lower end of the pressing plate 11 to press the rubber strip, so that the rubber strip is fixed. Then the second driving unit drives the two clamping arms 16 to act, so that the two clamping arms 16 clamp the rubber strip side by side. Then the first cylinder 12 continues to extend, and the blade on it can cut the rubber strip, and the rubber strip will be cut into rubber strip segments of a specified length, and there is still a certain length outside the two clamping arms 16, and this length is equal. Then the second driving unit drives the two clamping arms 16 to rotate outwards and approach (there is a gap between the two clamping arms 16), so that the rubber strip segments can form a circle, and the two ends of the rubber strip segments are exactly opposite and there is a small gap between them. Then the second driving unit drives the two clamping arms 16 to clamp the rubber strip segments and move upwards, so that the upper glue plate 17 just fits into the gap between the two ends of the rubber strip segments. In fact, the upper glue plate 17 is externally connected to glue through a conduit 18, and both sides of the upper glue plate 17 are covered with glue, so that both ends of the rubber strip segments can be glued. Then the second driving unit further reduces the distance between the two clamping arms 16, so that the two ends of the rubber strip segments contact and there is a certain extrusion force. Then the upper heating plate 19 and the lower heating plate 20 act synchronously under the action of the cylinder. The upper heating plate 19 and the lower heating plate 20 simultaneously extend into the space between the two clamping arms 16 and are exactly located above and below the connection of the rubber strip segments. Then the upper heating plate 19 and the lower heating plate 20 close the mold, clamp the connection of the rubber strip segments, and heat the connection. In this way, the production of a rubber ring is completed. Since heating takes time, in order to ensure continuous production, a number of bonding units are provided on the turntable. After one set of bonding units completes the work, the turntable will rotate, so that the vacant bonding unit enters the working position, thus avoiding the situation that the working efficiency is affected due to the need to wait for heating.

[0044] Actually, this all-in-one machine is mainly realized through intelligent control, including the central processor control of PLC, single-chip microcomputer, etc., as well as sensors for the coherent and accurate operation of each component, including the specific parameter settings for controlling the actions of motors and cylinders, etc. These are all achieved using conventional devices in the prior art.

[0045] Compared with the prior art, this fully automatic sealing strip cutting and sticking intelligent all-in-one machine realizes the feeding function through the feeding rack, realizes the state adjustment during the material transmission process through the limiting mechanism to prevent deflection, and through the integrated linkage design of the cutting mechanism, can effectively control the deformation amount of the material, ensure product quality, and through fully automatic cutting, gluing and sticking, improves the intelligence level of the entire equipment and realizes fully automatic production.
