Description

Technical Field

[0001] This utility model belongs to the field of bottle cap packaging, and in particular relates to a bag feeding device for bottle cap packaging. Background Technology

[0002] Bottle caps are extremely common packaging materials in daily life and industrial production. They are mainly used for sealing bottled products such as food and medicine, chemical raw materials, alcoholic beverages, and daily necessities, serving to seal the bottle and protect the product, while also having a certain aesthetic effect.

[0003] To facilitate the storage and transportation of bottle caps, they need to be packaged into bags in specific quantities after production. During this process, a bag-feeding device delivers the bags one by one to the packaging machine in an orderly manner. Existing bag-feeding devices typically consist of two clamping plates fixed to a swing arm. Once the clamping plates grip the bag, the swing arm rotates to deliver the bag. While this method can effectively deliver the bags, the swing arm may wobble during the delivery process, leading to instability. Alternatively, a robotic arm can be used to perform the bag-feeding action, but robotic arms are more expensive. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a bag feeding device for bottle cap packaging, which aims to solve the problem of unstable bag feeding process of existing bag feeding devices.

[0005] The present invention adopts the following technical solution:

[0006] The bag feeding device includes a frame, within which a pair of bag feeding mechanisms are provided. Each bag feeding mechanism includes a carrier, with a rotating seat and a rotating cylinder rotatably mounted on the front and rear of the carrier, respectively. A rotating block is rotatably mounted on the drive shaft of the rotating cylinder, and the other end of the rotating block is fixedly mounted on the rotating seat. A bag feeding seat is slidably mounted on the front of the rotating seat, and a bag feeding cylinder is mounted on the back. Hands are provided on both sides of the bag feeding seat, and a straight plate is provided at the rear of the bag feeding seat. The drive shaft of the bag feeding cylinder is connected to the rear of the straight plate. A lifting cylinder is provided downwards on the carrier, and a base frame is provided on the drive shaft of the lifting cylinder. A set of suction cups is provided on the base frame. A conveyor table is provided below each bag feeding mechanism on the frame.

[0007] Furthermore, the bag feeding seat is provided with a pair of adjusting seats, the adjusting seats have a sliding groove, the adjusting seats have an adjustment groove opposite the sliding groove, the sliding groove has a slider, the slider has a threaded hole, the tail of the gripper is inserted with a locking nut, the locking nut passes through the adjustment groove and the threaded hole in sequence and abuts against the bag feeding seat.

[0008] Furthermore, the carrier is provided with a pair of left and right side plates, and the side plates are provided with limiting posts, one of which is set forward and the other is set upward.

[0009] Furthermore, the carrier is provided with a guide plate facing downwards, the guide plate is provided with a guide sleeve, a guide rod is inserted into the guide sleeve, and the bottom of the guide rod is connected to the base frame.

[0015] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0016] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0017] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0018] Combination Figures 1-4As shown, the bag feeding device includes a frame 1, and a pair of bag feeding mechanisms are provided inside the frame 1. Each bag feeding mechanism includes a carrier 2. The carrier 2 is rotatably equipped with a rotating seat 3 and a rotating cylinder 4 at its front and rear, respectively. The drive shaft of the rotating cylinder 4 is rotatably equipped with a rotating block 5. The other end of the rotating block 5 is fixedly installed on the rotating seat 3. A bag feeding seat 6 is slidably provided on the front of the rotating seat 3, and a bag feeding cylinder 7 is provided on the back. Both sides of the bag feeding seat 6 are equipped with grippers 8. A straight plate 9 is provided at the tail of the bag feeding seat 6. The drive shaft of the bag feeding cylinder 7 is connected to the tail of the straight plate 9. A lifting cylinder 10 is provided downward on the carrier 2. The drive shaft of the lifting cylinder 10 is equipped with a base frame 11. A set of suction cups 12 is provided on the base frame 1. A conveyor table 13 is provided below each bag feeding mechanism on the frame 1.

[0019] After the bottle caps are produced, they can be packaged into bags in certain quantities for easy storage and transportation. During packaging, this bag-feeding device can be used to send the bags one by one to the packaging machine for quantitative packaging.

[0020] In this device, the frame is equipped with a pair of left and right bag feeding mechanisms. Each bag feeding mechanism is equipped with a packaging machine in front of it and a conveyor table below it. The conveyor table is used to convey a tray 14. The conveyor tray contains a stack of packaging bags with the bag openings facing forward.

[0021] like Figure 1 The diagram on the left shows the bag-feeding mechanism in the bag-picking state, and the diagram on the right shows the bag-feeding mechanism in the bag-feeding state. When this bag-feeding mechanism is used to send packaging bags one by one to the packaging machine in an orderly manner, the bag-feeding mechanism is located at the bag-picking station, the conveyor tray is located directly below the bag-feeding mechanism, and the two grippers are in the open state. First, the lifting cylinder drives the base frame to move downward until the suction cups pick up the packaging bags located in the conveyor tray. Then, the suction cups move upward a short distance, and both sides of the packaging bag are located in the grippers on the same side. The two grippers clamp the packaging bag tightly, and at the same time, the suction cups release the suction of the packaging bag and move downward to prepare to pick up the next packaging bag. At this time, the bag-feeding mechanism completes the bag picking.

[0022] After the two grippers clamp the packaging bag, the rotating cylinder drives the rotating seat to rotate upward. When the rotating seat rotates to the horizontal position, the packaging bag is placed vertically. Then the bag feeding cylinder drives the straight plate to move forward, and the straight plate pushes the bag feeding seat forward until the packaging bag is delivered to the packaging position of the packaging machine. Then the bag feeding mechanism completes the bag feeding.

[0023] In the bag feeding process described above, the suction cup first adheres to the packaging bag, then moves upward a short distance, and then the gripper clamps the bag opening. The rotating seat, driven by the rotating cylinder, rotates upward to a horizontal position. Finally, the straight plate pushes the bag feeding seat forward until it reaches the packaging position on the packaging machine. The entire bag feeding process is relatively stable.

[0024] In this device, the carrier 2 is provided with a pair of left and right side plates 15, and the side plates 15 are provided with limiting posts 16, one of which is arranged facing forward and the other is arranged facing upward. Two limiting posts are provided on each of the left and right sides of the carrier via the side plates. Figure 3 In the middle section, the bag feeding mechanism is in the bag-picking position. The left limit post faces upwards, and the right limit post faces forwards. These two limit posts primarily serve to limit and support the rotating seat. When the bag feeding mechanism is in the bag-picking position, the right limit post abuts against the rotating seat. When the rotating seat rotates to a horizontal position, the left limit post supports it. By setting two limit posts, the entire device becomes more stable during the bag feeding process.

[0025] In this structure, such as Figure 3 The carrier 2 is provided with a guide plate 17 facing downwards, and a guide sleeve 18 is provided on the guide plate 17. A guide rod 19 is inserted into the guide sleeve 18, and the bottom of the guide rod 19 is connected to the base frame 11.

[0026] When the suction cup is used to pick up the packaging bag located in the conveyor tray, the lifting cylinder drives the base frame to move vertically. When the base frame moves vertically, the guide rod moves vertically within the guide sleeve. The guide rod and guide sleeve play a guiding and limiting role, making the base frame more stable when moving vertically.

[0027] As a specific structure, such as Figures 1-2 The bag feeding seat 6 is provided with a pair of adjusting seats 20. The adjusting seat 20 has a sliding groove 21. The adjusting seat 20 has an adjustment groove 22 opposite to the sliding groove 21. The sliding groove 21 is provided with a slider 23. The slider 23 has a threaded hole (covered in the figure). The tail of the clamp 8 is inserted with a locking nut (not shown in the figure). The locking nut passes through the adjustment groove 22 and the threaded hole in sequence and abuts against the bag feeding seat 6.

[0028] In this structure, such as Figure 2The gripper 8 includes a connecting arm 81. The front end of the connecting arm 81 has a pair of inner and outer gripping blocks 82, and the rear end is fixed to the adjusting seat 20 by a locking nut. The inner gripping block is fixedly installed, and the outer gripping block is rotatably installed. A bag-clamping cylinder 83 is rotatably mounted on the connecting arm 81, and the drive shaft of the bag-clamping cylinder 83 is rotatably connected to the outer gripping block. When the left and right sides of the packaging bag are respectively located within the same pair of grippers, the two bag-clamping cylinders simultaneously drive the outer gripping block to rotate inward until the two pairs of grippers clamp the packaging bag.

[0029] In this embodiment, the mounting positions of the two grippers can be adjusted to accommodate packaging bags of different sizes. To adjust the mounting positions of the grippers, simply loosen the corresponding locking nuts and then push the connecting arm. The connecting arm will cause the slider to slide within the groove on the same side. Once the connecting arm is in place, tighten the locking nuts until the end of the locking nuts resists the bag feeding seat, and the slider stops sliding.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
