Description

Technical Field

[0001] This utility model relates to the field of chrysanthemum packaging technology, specifically a bag feeding device for a packaging machine. Background Technology

[0002] In the chrysanthemum processing industry, packaging is a key process to ensure product quality and distribution efficiency. Among them, the bag feeding device is the core component of the packaging machine, and its operational stability directly affects the packaging speed and the finished product qualification rate.

[0003] When adapting to chrysanthemum processing scenarios, existing packaging machine bag feeding devices often have the following problems: First, the packaging bags come in various sizes, making it difficult to quickly adapt to different sizes of packaging bags, which can easily lead to misalignment; second, the bags used for chrysanthemum packaging are mostly lightweight film bags, making it difficult for the bag feeding mechanism to achieve precise single-bag separation, which affects subsequent filling processes.

[0013] 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.

[0014] Please see Figure 1-3This embodiment discloses a bag feeding device for a packaging machine. The bag feeding device includes a frame 1, with a bag feeding mechanism and a conveyor table 2 respectively located at the front and rear of the frame 1. The bag feeding mechanism includes a fixed platform 3, the top surface of which is inclined forward and downward. Multiple rotatable conveyor belts 4 are provided on the top surface of the fixed platform 3. Baffles 5 are provided on both sides of the fixed platform 3, and a fixing frame 6 is provided between the baffles 5. A pair of left and right adjusting plates 7 are provided on the fixing frame 6, and a stop bar 8 is provided on the inner side of each adjusting plate 7. A connecting seat 9 is provided on the fixed frame 6 between two adjusting plates 7. The front of the connecting seat 9 is provided with an L-shaped pressure strip 10, and the back of the connecting seat 9 is provided with a stop post 11. A connecting rod 12 is vertically inserted into the connecting seat 9. The top of the connecting rod 12 is limited and installed above the connecting seat 9. A mounting seat 13 is provided at the bottom of the connecting rod 12. A bag-dividing wheel 14 is rotatably provided in the mounting seat 13. A part of the mounting seat is exposed below the bag-dividing wheel 14. A spring 15 is provided on the connecting rod 12 between the connecting seat and the mounting seat.

[0015] The working principle of the above embodiment is as follows: First, adjust the position of the adjusting plates according to the width of the packaging bag, so that the distance between the left and right adjusting plates matches the width of the packaging bag. Then, place the stack of packaging bags on the conveyor belt of the fixed platform, with the two adjusting plates located on the left and right sides of the packaging bags and the stop post located on the front side of the packaging bags. In this way, the adjusting plates limit the left and right sides of the packaging bags, and the stop post blocks the front end of the packaging bags, ensuring that the packaging bags maintain a stable posture.

[0016] When the device feeds bags, the conveyor belt starts to rotate, and the stack of bags tends to move forward. However, due to the obstruction and limitation of the baffles and posts, only the bottommost bag can move forward under the drive of the conveyor belt. The front end of the bag is inserted into the gap between the conveyor belt and the bag-separating roller. The bag-separating roller, under the action of a spring, makes close contact with the bag. Simultaneously, under the conveyor belt, the bag is smoothly transported to the conveyor table, completing one bag feeding cycle. Throughout the bag feeding process, the pressure strip can hold down the top of the bag to prevent it from tilting upwards during transport.

[0017] As a specific structure, Figure 2 In the middle, the top surface of the fixed platform 3 has a groove 16, and a block 17 is embedded in the groove 16. A locking screw 18 is screwed into the block 17, and the end of the locking screw 18 abuts against the bottom surface of the groove. A long rod 19 is provided on the block 17, and several inclined blocks 20 are provided on the long rod 19. Several pairs of pulleys 21 are rotatably provided on the inclined blocks 20.

[0018] When stacks of packaging bags are placed on the conveyor belt of the fixed platform, all the pulleys support the stacks of bags. Throughout the bag feeding process, the pulleys reduce friction during transport, making the bag conveying smoother. In practice, the position of the inserts within the slots can be easily adjusted by tightening or loosening the locking screws. The long rod also moves all the inclined blocks together, adjusting the position of the pulleys to accommodate packaging bags of different sizes.

[0019] In this device, the fixed frame 6 is provided with a pair of upper and lower sliding rods 22, and the sliding rods 22 are provided with a pair of left and right sliding seats 23. The adjusting plate 7 is installed on the sliding seats 23. The fixed frame 6 is rotatably provided with a lead screw 24. The lead screw 24 has a pair of threaded sections with opposite directions. Both ends of the lead screw 24 pass through the baffle 5 on the same side and are provided with a rotating handle 25. The sliding seat 23 has a threaded sleeve, and the threaded sleeve is installed on the lead screw.

[0020] When it is necessary to adjust the distance between the left and right adjustment plates, the screw can be rotated by turning the rotary handle, which will cause the slide to move in opposite directions on the slide rod, thereby adjusting the distance between the adjustment plates to meet the bag feeding needs of packaging bags of different widths.

[0021] In addition, a pair of rotating rods 26 are rotatably mounted on the fixed platform 3, and multiple conveyor belts 4 are sleeved between the two rotating rods. A driven wheel 27 is mounted on the rear rotating rod. A drive motor 28 is mounted inside the fixed platform 3. A drive wheel (obscured in the figure) is mounted on the drive shaft of the drive motor. A drive belt is sleeved between the drive wheel and the driven wheel.

[0022] In this device, when the conveyor belt needs to rotate to transport packaging bags, the drive motor starts working, and the drive motor drives the drive wheel to rotate. Under the linkage of the drive belt, the driven wheel drives the rear rotating rod to rotate, and all the conveyor belts rotate accordingly.

[0023] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
