Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, and in particular to a bag positioning device. Background Technology

[0002] In the prior art, material bags are bag-shaped packaging materials used to hold materials. They are simple in structure, inexpensive, and easy to use.

[0003] Modern material bags are all inelastic structures, with fixed width and height. However, because the cost of material bags is low, their quality is not strictly controlled. During the manufacturing process, the bag opening is prone to be crooked, which means that when the material bag is used, its position cannot be fixed after it arrives at the work station during mechanical transmission. The material bag is crooked relative to the material gate and its height is inconsistent.

[0004] During filling, the cylinder fingers grip the upper edge of the bag, but due to varying lengths, the gripping point is either too high or too low. This results in poor fit between the bag opening and the filling gate, causing leakage or spillage. This leads to product waste and poses a hazard to continuous automated production, requiring frequent machine shutdowns for cleaning. Sprayed product must be disposed of as waste. The powder floating in the air also poses a health risk to personnel. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a bag positioning device, characterized by including a left-right adjustment structure, a height positioning structure, a frame, and an inclined plate;

[0006] The inclined plate is mounted on the frame, and the inclined plate is equipped with a left-right adjustment structure and a height positioning structure.

[0007] The left-right adjustment structure comprises a base plate, cylinder one, cylinder two, a linear guide rail, sliders, and left-right adjustment plates. The cylinders are fixed to the base plate by supports. A linear guide rail is also mounted on the base plate, and two sliders are mounted on the linear guide rail. Connecting plates are mounted on each slider, and these plates are connected to the left-right adjustment plates via a connecting structure. The left-right adjustment plates are located on the front side of the inclined plate, and the mounting plates are located on the rear side of the inclined plate.

[0008] The height positioning structure includes a third cylinder, a height adjustment plate, a vacuum suction cup, and a photoelectric sensor. The inclined plate has mounting holes, and the third cylinder is mounted on the inclined plate via a support. The cylinder rod passes through the mounting holes and connects to the height adjustment plate. The vacuum suction cup and photoelectric sensor are fixed to the inclined plate via the mounting plate.

[0009] The height adjustment plate has a 7-shaped cross-section.

[0010] The photoelectric sensor, cylinder one, cylinder two, cylinder three, vacuum suction cup, and vacuum solenoid valve are connected to the controller respectively.

[0011] The photoelectric sensor transmits the received signal to the controller, which then controls the operation of cylinder one, cylinder two, cylinder three, the vacuum suction cup, and the vacuum solenoid valve.

[0012] The vacuum suction cup is connected to the vacuum solenoid valve.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention relates to a bag fixing and positioning device. During the filling process, the incoming bag is positioned, and then the bag is removed from the inclined plate 3 by the hand gripper in the next process and placed under the filling gate. The bag is then pulled open by the side-opening suction cups, opening the filling gate for filling. Because of the positioning function of this invention, the bag is prevented from being too high or too low, ensuring a better fit between the bag opening and the filling gate, and preventing leakage or spillage during filling. This invention solves the problem of spillage in the next process caused by the bag shifting position at this station during the previous process's transport. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described with reference to the accompanying drawings:

[0022] Example 1

[0023] This utility model introduces a high-efficiency bag positioning device, which realizes precise positioning and adjustment of the bag.

[0024] The structural components include:

[0025] Frame: As the supporting structure for the entire device, it ensures the stability and durability of the device.

[0026] Inclined plate: Fixed to the frame, it has an inclined structure, which facilitates the placement and adjustment of material bags.

[0027] Left and right adjustment structure: Installed on the inclined plate, it consists of a base plate, cylinder one, cylinder two, linear guide rail, slider, left and right adjustment plate, and connecting plate. The linear guide rail on the base plate cooperates with the slider, and driven by cylinder one and cylinder two, the material bag is moved horizontally.

[0028] Cylinder 1 and Cylinder 2: Fixed to the base plate by a support, they are used to push the slider, thereby driving the left and right adjustment plates to make horizontal adjustments.

[0029] Connecting plate: Connects the mounting plate to the left and right adjustment plates via a connecting structure.

[0030] Height positioning structure: Located on the inclined plate, it includes cylinder three, height adjustment plate, vacuum suction cup and photoelectric sensor.

[0031] Cylinder 3: Mounted on the inclined plate via a support, its cylinder rod passes through the mounting hole and connects to the height adjustment plate to control the vertical position of the material bag.

[0032] Vacuum suction cup: Used to adsorb material bags and ensure their stability during adjustment.

[0033] Photoelectric sensor: Used to detect the position of the material bag and achieve automatic positioning.

[0034] The unique cross-sectional design of the height adjustment plate provides excellent support and stability, while facilitating the placement and adjustment of the material bags.

[0035] Through the above design, this bag positioning device can realize the left and right adjustment and height positioning of the bag, which greatly improves the efficiency of bag placement and facilitates the subsequent material filling of the bag.

[0036] Example 2

[0037] Working materials

[0038] In use, this utility model is placed on the filling device and positioned behind the conveying device. Cylinder 1 and Cylinder 2 are initially in the retracted piston rod position, while Cylinder 3 is initially in the extended piston rod position. At this time, the left and right adjustment plates are open, and the height adjustment plate is at the top. When the bag falls onto the height adjustment plate, the piston rods of Cylinder 1 and Cylinder 2 extend, driving the left and right adjustment plates to move. The left and right adjustment plates push the bag to the middle. At this time, Cylinder 3 slowly retracts through the speed control valve, and the bag slowly descends. When the photoelectric sensor detects that the bag opening has reached the preset position, it transmits a signal to the vacuum solenoid valve, and the vacuum suction cup quickly picks up the bag, thus satisfying the left, right, and height positioning of the bag.
