Description

Technical Field

[0001] This utility model belongs to the field of feeding technology for packaging machines, specifically a feeding device for packaging machines. Background Technology

[0002] The feeding device for the bag opener is an important auxiliary component used by the bag opener to automatically unpack and transport materials. It is mainly used to transport the bagged materials to be opened in an orderly and stable manner to the working area of ​​the bag opener, so as to realize the automated feeding and opening process.

[0003] The specific design and structure of the feeding device for a bag opener may vary depending on the manufacturer and application requirements, but generally they include the following key components: belt conveyor and positioning and clamping device, etc. The belt conveyor is suitable for horizontal or inclined conveying of bagged materials, has high stability, and is suitable for lightweight packaging bags. The positioning and clamping device works with cylinders, baffles and other mechanisms to achieve precise positioning, and the clamping device fixes the packaging bag to prevent shaking when opening the bag.

[0004] Traditional bag opener conveyor systems lack automated low-level gripping capabilities for material bags stacked on the ground, requiring the use of forklifts, pallets, and other auxiliary tools to lift them to the belt height, increasing the equipment's footprint and energy consumption. After unloading, waste bags often fall into the collection device along with residual materials, requiring separate sorting and separation. This not only increases labor but may also lead to packaging bag fragments and dust mixing into the materials, affecting product quality. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a feeding device for a packaging machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is a feeding device for a bag opening machine, including a transmission frame, a transmission belt on the transmission frame, a first motor bracket on the side of the transmission frame, a transmission motor on the first motor bracket, a transmission rod sleeved on the transmission belt fixedly connected to the output end of the transmission motor, symmetrical transmission grooves on the transmission frame, transmission rollers slidably arranged in the two transmission grooves, mounting plates on the transmission rollers, the mounting plates and the transmission belt fixedly connected through the transmission plates, a battery on the mounting plate, an electric cylinder on the side of the battery, a piercing frame on the output end of the electric cylinder, a bag opening compartment on the side of the transmission frame, a cylinder mounting bracket on the top of the bag opening compartment, a cutting cylinder fixedly mounted on the cylinder mounting bracket, a cutting blade holder on the output end of the cutting cylinder, a waste bag compartment on the side of the bag opening compartment, and an infrared sensor, model RE200B, on the waste bag compartment.

[0007] Preferably, mounting blocks are symmetrically arranged at the bottom of the transmission frame, and a flipping block is rotatably arranged between the mounting blocks. A flipping rod is symmetrically arranged on the flipping block, and two sets of fixing plates are respectively arranged on the two flipping rods. A flipping cylinder is arranged on each of the two sets of fixing plates, and a flipping plate is fixedly arranged on the output end of the two sets of flipping cylinders. A second motor bracket is arranged on the side of the mounting block, and a flipping motor is installed on the second motor bracket. The output end of the flipping motor is fixedly connected to the top of the flipping block.

[0008] Preferably, the transmission belt is provided with a limiting plate, and the limiting plate is provided with a puncture groove. The puncture groove is correspondingly provided with a puncture frame, and the puncture frame and the puncture groove of the limiting plate are precisely aligned to ensure accurate puncture position, avoid uneven damage to the packaging bag, and reduce material leakage.

[0009] Preferably, the battery is used to power the electric cylinders, and each electric cylinder has a battery electrically connected to it, eliminating the need for external cables, removing the risk of cable tangling, simplifying the structure, and making it suitable for frequently moving parts.

[0010] Preferably, the bottom end of the transmission frame is provided with a support leg. The support leg adopts a rigid structure to provide a stable foundation support, reduce vibration during equipment operation, protect precision components from vibration, and extend the overall service life.

[0011] Preferably, the drive motor, electric cylinder, infrared sensor, and tilting motor are all connected to an external controller, which is used for start-stop control of the drive motor, electric cylinder, infrared sensor, and tilting motor.

[0012] The advantages of this invention are as follows: when the material is unloaded, the material bag continues to be conveyed by the conveyor belt, thereby pulling the empty material bag away from the bag hopper and moving it to the waste bag hopper. Then, the controller controls the electric cylinder to retract the piercing frame, releasing the fixation of the material bag. The waste bag falls into the waste bag hopper due to gravity. This method of using gravity to separate the material from the empty material bag is effective, and at the same time, the waste bags can be collected separately to avoid the waste bags from mixing with the material.

[0013] By linking the flipping motor with the flipping plate, the automatic grabbing, transfer and positioning of material bags on the ground is realized, replacing the traditional manual feeding. The flipping motor adopts a high torque servo motor, which, together with two sets of flipping cylinders, accurately places the material bags onto the transmission belt. Attached Figure Description

[0018] The transmission frame 1 has a bag opening compartment 30 on its side, and a cylinder mounting bracket 24 is provided at the top of the bag opening compartment 30.

The limit plate 12 restricts the lateral movement of the material bag and ensures that the piercing groove 13 is precisely aligned with the piercing frame 11 below. The mounting plate 8 moves synchronously with the drive belt 2 through the drive plate 23. The electric cylinder 9 is powered by the battery 14 and pushes the piercing frame 11 upward through the piercing groove 13, piercing the bottom of the material bag and fixing it to prevent slippage during subsequent cutting.

[0025] During operation, in order to collect the waste bags, after the material is unloaded, the infrared sensor 29 on the waste bag bin 27 detects that the waste bag has moved above the waste bag bin 27 and sends a signal to the controller. Then the controller controls the electric cylinder 9 to retract the piercing frame 11 and release the fixation of the material bag. The waste bag falls into the waste bag bin 27 due to gravity.

[0026] Working principle: In order to fix the material bag, the drive motor 5 drives the drive belt 2 to rotate and transport the material bag to the limit plate 12. The limit plate 12 restricts the lateral movement of the material bag and ensures that the piercing groove 13 is precisely aligned with the piercing frame 11 below. The mounting plate 8 moves synchronously with the drive belt 2 through the drive plate 23. The electric cylinder 9 is powered by the battery 14 and pushes the piercing frame 11 upward through the piercing groove 13, piercing the bottom of the material bag and fixing it to prevent slippage during subsequent cutting.

[0027] In order to transport the material bag, the flipping motor 17 is started, driving the flipping block 18 to rotate, which in turn drives the flipping plate 22 to flip downward to above the material bag on the ground; the two sets of flipping cylinders 20 extend synchronously, pushing the flipping plate 22 to fit against the top of the material bag and fix the material bag, and the flipping motor 17 rotates in the opposite direction to lift the material bag above the transmission belt 2.

[0028] In order to cut and open the material bag, the transmission belt 2 sends the fixed material bag into the opening chamber 30.
