Description

Technical Field

[0001] The present invention relates to the technical field of easy-open lid packaging equipment, and in particular to an easy-open lid automatic packaging equipment. Background Art

[0002] As an opening device for containers such as beverage cans and food cans, easy-open lids are widely favored by the market for their ease of use and good sealing performance. With the growth of market demand, the production volume of easy-open lids has also increased. Traditional manual or semi-automatic packaging methods can no longer meet the efficiency requirements of large-scale production. Therefore, automated packaging equipment has become one of the key factors in enhancing the competitiveness of easy-open lid manufacturers.

[0003] The Chinese invention patent with the patent announcement number CN118753609B discloses an intelligent automatic packaging production line for easy-open lids, which includes two conveyor belts for conveying finished easy-open lid bodies, baffles are arranged on both sides of each conveyor belt, and support legs are fixedly installed on the front and rear of the lower surface of each baffle. In addition, a U-shaped frame is fixedly installed on the top of the two baffles on each conveyor belt by screws. However, in actual application, this design has some shortcomings:

[0004] 1. High cost and low efficiency: When the above patent is in use, an additional robot is required to remove the packaging bag with the easy-open lid and flexibly cover the entrance end of the next packaging bag on the circle formed by the semicircular plate and the rear end of the first semicircular conveyor plate. This process not only increases the cost of the production equipment, but also takes a long time to replace the packaging bag, which affects the overall packaging efficiency.

[0005] 2. The problem of packaging bag positioning: Since the packaging bag is made of soft material and is easy to deform, its entrance end may be in a closed state. In this case, it is difficult to ensure that the entrance end of each packaging bag can be accurately placed in the specified position through the movement of the robot, which may cause the subsequent easy-open lid to fail to enter the interior of the packaging bag smoothly, affecting the packaging effect. Summary of the invention

[0059] Initially, if Figure 3As shown, the circular hole 901 on the lower side is connected with the through hole 701 on the lower side, so that the first air extraction channel 501 on the lower side is connected with the hollow frame 11, while the circular hole 901 on the upper side is not connected with the through hole 701 on the upper side, so the first air extraction channel 501 on the upper side is not connected with the hollow frame 11; the storage frame 35 is filled with a proper amount of staples, and the compression spring 38 is in a compressed state; first, the device is installed at a designated position, and then a proper amount of packaging bags are placed in the arc channel 20, and then a collection frame is placed under the guide frame 43, and then the controller 4 controls the dual-axis motor 21 to drive the swing frame 22 to rotate downward, and the swing frame 22 can drive the push plate 23 and the rubber block 41 The push plate 23 rotates downward to enter the arc channel 20, and the side of the push plate 23 contacts the side of the rearmost packaging bag, and the rubber block 41 contacts the surface of the conveyor belt 4002 of the conveying assembly 40. The push plate 23 continues to rotate to push the packaging bag in the arc channel 20 forward, and the rubber block 41 can drive the conveying assembly 40 to rotate through the friction between it and the conveyor belt 4002, thereby assisting the packaging bag to move forward along the arc channel 20 until the frontmost packaging bag contacts the bottom of the rotating plate 5; then the controller 4 can control the vacuum pump 10 to extract the air inside the lower first vacuum channel 501 through the connecting pipe 12 and the hollow frame 11, so that the bottom of the rotating plate 5 generates The suction force sucks the packaging bag at the front side of the arc channel 20, and then the controller 4 controls the dual-axis motor 21 to drive the swing frame 22 to rotate upward at a specified angle, so as to drive the push plate 23 to move backward along the arc channel 20 for a distance. The push plate 23 can drive the conveying component 40 to reverse through the rubber block 41, so as to drive the remaining packaging bags in the arc channel 20 to move backward for a distance and separate from the packaging bags at the bottom of the rotating plate 5. Then the controller 4 controls the first driving motor 6 to drive the rotating plate 5 to rotate 180 degrees. The rotating plate 5 can drive the packaging bags thereon to rotate 180 degrees upward. At this time, the packaging bags on the rotating plate 5 will not be scraped by the remaining packaging bags in the arc channel 20. The bag is rubbed and falls, and then the controller 4 controls the second electric push rod 25 to drive the lifting plate 26 to move downward, and controls the solenoid valve 28 to open, so that the vacuum pump 10 can extract the air inside the second vacuum channel 2601 through the connecting pipe 12 and the shunt pipe 27, so that suction is generated at the bottom of the lifting plate 26. When the bottom of the lifting plate 26 contacts the packaging bag on the rotating plate 5, the bottom of the lifting plate 26 will suck the top of the packaging bag. Then the controller 4 controls the second electric push rod 25 to drive the lifting plate 26 to move upward by a specified distance, so as to pull the top of the packaging bag to move upward by a specified distance. At this time, the bottom of the packaging bag is sucked by the rotating plate 5, so that the entrance end of the packaging bag can be opened;During the preparation of the packaging bag, the conveyor continuously conveys the easy-open lid to the curved plate 2 and enables the easy-open lid to move to the left along the curved plate 2. When the laser sensor 13 detects that an easy-open lid passes below it, it means that the number of easy-open lids between the laser sensor 13 and the partition 16 reaches a preset value. At this time, the laser sensor 13 sends a signal. After receiving the signal, the controller 4 controls the third drive motor 15 to drive the partition 16 to rotate downward ninety degrees to divide the easy-open lid on the curved plate 2 into two sections. Subsequently, the controller 4 controls the first electric push rod 14 to drive the third drive motor 15 and the partition 16 to move to the left. The partition 16 can move the easy-open lid on the left side. The first section of the easy-open lid on the side is quickly pushed to the left to enter the packaging bag at the top of the rotating plate 5. Since the top of the rotating plate 5 is an inclined surface, the easy-open lid inside the packaging bag can be tilted to the left and the right, thereby preventing the easy-open lid in the packaging bag from tipping toward the entrance end. Then the controller 4 controls the first electric push rod 14 to drive the third drive motor 15 and the partition 16 to move rightward and reset, and controls the third drive motor 15 to drive the partition 16 to reverse 90 degrees and reset. At the same time, the controller 4 controls the solenoid valve 28 to close, so that the bottom of the lifting plate 26 no longer sucks the top of the packaging bag; then the controller 4 controls the third electric push rod 30 to drive the connecting plate 31 When the pressing plate 34 contacts the top right side of the packaging bag, the pressing plate 34 will squeeze the top right side of the packaging bag and move it downward, so that the entrance end of the packaging bag is closed. Subsequently, the pressing plate 34 contacts the rotating plate 5 and clamps the entrance end of the packaging bag. At this time, the pressing plate 34 and the sliding bar 33 stop moving downward, and the connecting plate 31 will drive the vertical plate 32 to continue moving downward. The vertical plate 32 will first enter the storage frame 35 and push a staple inside the storage frame 35 downward through the slotted hole 3501, and the vertical plate 32 can block the remaining staples in the storage frame 35, so that The stapler can pass through the entrance end of the packaging bag and contact the shaping groove 502, and the shaping groove 502 will squeeze the lower end of the stapler to bend it, so that the packaging bag can be sealed. The above principle is similar to that of a stapler, and no further elaboration is made here. Then the controller 4 will control the third electric push rod 30 to drive the connecting plate 31 to move upward and reset, and the connecting plate 31 will drive the vertical plate 32, the sliding rod 33 and the pressing plate 34 to move upward and reset, so that the vertical plate 32 is away from the storage frame 35. At this time, the compression spring 38 will slightly return to its original state, driving the sliding plates 37 on the front and rear sides to move toward the side close to each other, so that the next stapler can be pushed to the bottom of the vertical plate 32.Then the controller 4 will control the second driving motor 8 to drive the rotating cylinder 9 to rotate 90 degrees, so that the other first exhaust channel 501 is connected to the hollow frame 11. At this time, the rotating plate 5 no longer absorbs the packaging bag with the easy-open lid thereon, and then repeat the above operation to make the rotating plate 5 rotate 180 degrees to drive the next packaging belt to rotate upward, and the packaging bag with the easy-open lid will fall down onto the unloading frame 3 with the rotation of the rotating plate 5, and slide down along the unloading frame 3 and the rubber film 44 into the guide frame 43, and finally fall down along the guide frame 43 into the inside of the collection frame, so that The packaging of the easy-open lid is completed automatically. The controller 4 controls the fourth electric push rod 45 to drive the guide frame 43 to intermittently reciprocate back and forth, and the discharging position of the packaging bag can be adjusted to ensure that the packaging bags with the easy-open lid fall evenly into the collection frame to avoid excessive accumulation and achieve the effect of automatic arrangement. The telescopic connecting rod 42 and the rubber membrane 44 will be adaptively extended and retracted with the movement of the guide frame 43 to ensure that the packaging bags can pass smoothly. When the staples in the storage frame 35 are used up, the blocking cover 39 can be slid open, and then the staples are added to the storage frame 35. ;
