Description

Technical Field

[0001] This utility model belongs to the field of automatic packaging technology, and more specifically, it relates to a feeding device for an automatic bag packaging machine. Background Technology

[0002] A pre-filled bag automatic packaging machine is a device that automatically completes the packaging of bagged products and is widely used in the food, pharmaceutical, and chemical industries. During the operation of a pre-filled bag automatic packaging machine, packaging bags need to be fed into the machine for packaging operations; therefore, a feeding device is required. Existing feeding devices for pre-filled bag automatic packaging machines mainly consist of a placement seat, conveyor rollers, and a robotic arm. The packaging bag is placed inside the placement seat, and a drive mechanism moves the conveyor rollers to a convenient location for pickup. The robotic arm then picks up the packaging bag and places it into the packaging machine for packaging.

[0003] Existing application number CN201320509904.8 discloses a bag-type packaging machine, comprising a main body on which a bag-feeding conveyor, a bag-loading device, a zipper bag opening and heat-coding device, a stand-up pouch opening device, a bag-opening device, a first filling and shaking device, a second filling and shaking device, an exhaust and heat-sealing device, a cold-sealing device, a discharge conveyor, and an electrical control panel located above the main body are arranged in sequence. This structure allows each process to cooperate to achieve an automated production mode. This machine is highly adaptable, fast, and reliable, making it an ideal choice for the food and chemical industries.

[0004] Based on the above, when the existing automatic bag packaging machine feeds the bags, the bags may become wrinkled during the feeding process, resulting in problems such as poor feeding and positioning difficulties. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a feeding device for an automatic bag packaging machine, which solves the problem that when the feeding device of the existing automatic bag packaging machine feeds the packaging bag, the packaging bag may be wrinkled during the feeding process, resulting in poor feeding and positioning difficulties.

[0006] The purpose and function of this utility model's feeding device for an automatic bag packaging machine are achieved through the following specific technical means:

[0007] A feeding device for an automatic bag packaging machine includes a feeding base;

[0008] A feeding rack, which is fixedly installed on the upper part of the feeding base;

[0009] A protective box, which is bolted to the left and right sides of the feeding rack;

[0010] A rotating shaft is vertically slidably connected inside the feeding rack;

[0011] A drive rod, which is vertically slidably connected inside the feed rack;

[0012] A drive motor, which is fixedly installed inside the feeding base;

[0013] A feeding assembly, wherein the feeding assembly is disposed inside the feeding rack;

[0014] A smoothing component is disposed inside the feed rack.

[0015] Furthermore, the feeding assembly includes:

[0016] The electric push rod is provided in two sets, and the two sets of electric push rods are fixedly installed on the left and right sides of the feeding frame.

[0017] The drive block is provided in two sets. The two sets of drive blocks are fixedly installed at the ends of two sets of electric push rods and are rotatably connected to both ends of the rotating shaft.

[0018] Furthermore, the feeding assembly also includes:

[0019] A conveyor motor, which is bolted to the inside of the right-side drive block;

[0020] The conveying roller shaft is fixedly installed inside the rotating shaft.

[0021] Furthermore, the feeding assembly also includes:

[0022] A rotating disk, which is fixedly installed inside the drive motor;

[0023] The second transmission rod has one end eccentrically hinged inside the rotating disk;

[0024] The guide groove is formed at the bottom of the feeding rack;

[0025] The top head is slidably connected inside the guide groove and hinged to one end of the second transmission rod.

[0026] Furthermore, the smoothing component includes:

[0027] The first rack is fixedly installed inside the drive block and slidably connected to both sides of the feed rack;

[0028] A drive gear is rotatably connected to both sides of the feeding frame, and the drive gear meshes with the first rack.

[0029] The second rack is fixedly installed at both ends of the drive rod and slidably connected to both sides of the feed rack. The second rack and the drive gear mesh with each other.

[0030] Furthermore, the smoothing component also includes:

[0031] A smoother, which is fixedly mounted on the bottom of the drive rod;

[0032] The drive shaft is provided in two sets, and the two sets of drive shafts are rotatably connected inside the smoother.

[0033] The elastic torsion spring is provided in two sets. The two sets of elastic torsion springs are fixedly installed inside the smoother and the two sets of elastic torsion springs are respectively fixedly installed inside the two sets of drive shafts.

[0034] Furthermore, the smoothing component also includes:

[0035] The first transmission rod is provided in multiple sets, with every two sets of the first transmission rods fixedly installed at both ends of a transmission shaft.

[0036] The flattening rollers are provided in two sets, with each set of flattening rollers fixedly installed at the end of the first transmission rod of every two sets.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] Firstly, this utility model has a feeding assembly. When the electric push rod drives the conveying roller to transport the packaging bags inside the feeding rack, the drive motor simultaneously drives the top head to slide back and forth in the guide groove to lift the packaging bags, which facilitates the conveying roller to transport the packaging bags and greatly improves the conveying efficiency of the packaging bags. Lifting the packaging bags increases the friction of the conveying roller and reduces slippage of the conveying roller, which would make it inconvenient to feed the packaging bags.

[0039] Secondly, this utility model has a smoothing component. Through the cooperation of the first rack, the drive gear and the second rack, when the conveying roller axially conveys the packaging bag downwards, the smoother moves upwards. When the conveying roller axially moves upwards, the smoother moves downwards to press and smooth the packaging bag, so as to avoid the packaging bag from wrinkling during conveying, which would affect positioning, feeding and other functions.

[0040] This invention has the advantages of smooth material feeding, wrinkle smoothing, and ease of use, which greatly improves the conveying efficiency of packaging bags. Moreover, after the conveying rollers convey the packaging bags, the remaining packaging bags are pressed and smoothed, which greatly reduces the formation of wrinkles in the packaging bags.
