Description

Technical Field

[0001] This utility model relates to the field of injection molded product technology, specifically an automatic lid closing device. Background Technology

[0002] Injection molding is a method of industrial product manufacturing. Products are typically made using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting. An injection molding machine heats and melts the plastic, then injects it into the cavity of a mold. After cooling and solidification, the melt is demolded. Bottles produced by injection molding are common daily necessities. In actual production, injection molding machines cannot automatically cap the bottles, therefore automatic capping devices are required.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1 - Figure 5 As shown, this utility model provides a technical solution for an automatic lid closing device, including a platform 1, a lifting sliding mechanism 2 slidably arranged on the platform 1, and pressure plates 5 arranged in a linear array slidably on the lifting sliding mechanism 2. Each pressure plate 5 is rotatably connected to two inclined rods 6, which are staggered and intersecting each other. The beginning and end of each group of adjacent inclined rods 6 are rotatably connected to each other. A threaded rod 7 is rotatably arranged on the lifting sliding mechanism 2, and a threaded block is threadedly sleeved on the outer side of the threaded rod 7. The threaded block is fixedly connected to the bottom of the leftmost pressure plate 5, and the rightmost pressure plate 5 is fixed to the lifting sliding mechanism 2. The leftmost pressure plate 5 is threaded onto the outside of the threaded rod 7 via a threaded block. The other pressure plates 5 are each provided with through holes at their corresponding positions relative to the threaded rod 7. The threaded rod 7 is located inside the cavity of the through hole, and the outer wall of the threaded rod 7 does not contact the inner wall of the through hole.

[0020] like Figure 3 As shown, the lifting and sliding mechanism 2 includes a sliding frame 201 that is horizontally slidably mounted on the platform 1. A lifting plate 202 is slidably mounted inside the sliding frame 201. Each pressure plate 5 is mounted on the lifting plate 202. A first cylinder 203 is installed on both the platform 1 and the sliding frame 201. The telescopic ends of the two first cylinders 203 are fixedly connected to the side wall of the sliding frame 201 and the upper part of the lifting plate 202, respectively. Two long slots are opened on one side of the sliding frame 201. Long rods are slidably mounted in the long slots and fixedly mounted on the upper part of the platform 1. Through vertical holes are opened at the four corners of the lifting plate 202. Vertical rods are slidably mounted in the vertical holes and fixedly mounted on the sliding frame 201. Platform 1 works in conjunction with a robotic arm. After multiple bottles are injection molded, the robotic arm simultaneously transports the bottles to platform 1 and places each bottle on a limiting mechanism 3 for positioning. At this time, the pressure plate 5 is located on one side of the bottle and directly below the opened bottle cap. The first cylinder 203 drives the lifting plate 202 to rise, and the pressure plate 5 pushes the bottle cap to rotate towards the top of the bottle. Then the lifting plate 202 stops moving. Then another first cylinder 203 drives the sliding frame 201 to move, and the sliding frame 201 drives the pressure plate 5 to move towards the bottle cap and pushes the bottle cap to close until the pressure plate 5 moves directly above the bottle. Then the first cylinder 203 drives the lifting plate 202 to descend and press the bottle cap closed. After the bottle cap is closed, the sliding frame 201 and the lifting plate 202 are reset. Then the robotic arm removes and transports the bottle with the cap closed. The threaded rod 7 is rotated according to the width of the bottle, and the distance between each pressure plate 5 is adjusted by using the tilting rod 6, so that the pressure plate 5 is located on one side of the bottle.

[0021] like Figure 2 and Figure 4 As shown, a rectangular array of limiting mechanisms 3 is provided on platform 1. The limiting mechanism 3 includes a circular array of limiting frames 301. A slider 302 is fixedly provided at the bottom of the limiting frame 301. A through-type track groove 4 is provided on the upper part of platform 1 and at the corresponding position of each limiting frame 301. Each slider 302 slides in the cavity of each track groove 4. An adjustment mechanism 8 is provided on platform 1 to adjust the slider 302 to slide in the cavity of the track groove 4. The vertical cross section of the slider 302 is an I-shaped structure, and the vertical cross section of the track groove 4 is an I-shaped cavity.

[0022] like Figure 2 and Figure 4 As shown, a mounting plate is fixedly installed at the bottom of the platform 1. The adjustment mechanism 8 includes an adjustment plate 801 that is slidably installed between the platform 1 and the mounting plate. An adjustment ring is fixedly installed at the corresponding position of each limiting mechanism 3 on the adjustment plate 801. An adjustment rod 802 is rotatably connected to the bottom of each slider 302. The bottom end of each adjustment rod 802 in the same group is rotatably connected to the corresponding adjustment ring.

[0023] like Figure 4 As shown, a second cylinder 9 is mounted on the mounting plate. The output end of the second cylinder 9 is fixedly connected to the bottom of the adjusting plate 801. Guide holes are provided at the four corners of the upper part of the adjusting plate 801. Guide rods 10 are slidably arranged in the guide holes and are fixedly connected between the platform 1 and the mounting plate.

[0024] like Figure 4As shown, a buffer frame 13 is slidably arranged on one side of the limiting frame 301, and a vertical roller 14 and an inclined roller 15 are rotatably arranged on one side of the buffer frame 13. Two through holes are opened on one side of the limiting frame 301, and a stabilizing rod 16 is slidably arranged in the through holes. One end of the stabilizing rod 16 is fixed to the other side of the buffer frame 13, and a blocking block is fixed to the other end of the stabilizing rod 16. A spring is slidably sleeved on the outside of the stabilizing rod 16, and the spring is located between the buffer frame 13 and the limiting frame 301. By tilting the inclined roller 15, the bottle can be stably inserted between the vertical rollers 14 in the same group. The vertical rollers 14 hold the bottle in place, thus stabilizing it. The second cylinder 9 drives the adjusting plate 801 to rise and fall. The adjusting plate 801, through the adjusting ring and adjusting rod 802, drives the limiting frame 301 to slide on the track groove 4, thereby adjusting the distance between the vertical rollers 14 in the same group. By adjusting the position of the limiting frame 301, the vertical rollers 14 can slightly squeeze the bottle. At this time, the vertical rollers 14 compress the spring, and the spring force forms a buffer to prevent the vertical rollers 14 from squeezing too much and affecting the picking and putting of the bottle.

[0025] like Figure 1 - Figure 3 As shown, a servo motor 11 is installed on one side of the lifting plate 202. The output end of the servo motor 11 is fixedly connected to the end of the threaded rod 7. A controller 12 is installed on the upper part of the platform 1. The controller 12 is electrically connected to the power supply, and the servo motor 11 is electrically connected to the controller 12. The controller 12 controls the start and stop of the servo motor 11, the first cylinder 203 and the second cylinder 9, as well as the speed and rotation angle of the output shaft of the servo motor 11, and simultaneously controls the extension and retraction length of the piston rods on the first cylinder 203 and the second cylinder 9. Since the specific structure of the controller 12, as well as the connection method and usage method of the related structure, are all existing technologies, this application will not elaborate further.
