Description

Technical Field

[0001] The utility model relates to the technical field of three-side sealing bag making machines, in particular to a barrel material unloading rack of the three-side sealing bag making machine. Background Art

[0002] Three-side seal bags, also known as sealed bags, are a common form of plastic packaging. They are characterized by heat-sealing the sides and bottom of the packaging material, while the top is usually left open or designed with a tear-off notch for easy opening. This type of packaging offers excellent sealing, visual appeal, portability, and storage convenience, along with a simple structure and production process. It is widely used in a variety of industries, including food, medicine, chemicals, and electronics.

[0003] The raw film used for bag making is usually rolled onto a barrel shaft to form a cylindrical shape and placed on a discharge rack for feeding to subsequent processes. The currently commonly used discharge racks have the following problems when in use: 1. When the raw film for bag making is about to run out, the bag making machine will not stop immediately. The film will continue to be conveyed under the traction force of the bag making machine, so that the end of the film will be separated from the barrel shaft. When the next batch of cylindrical raw film needs to be connected, it not only saves time and effort, but also causes waste of the next batch of cylindrical raw film; 2. Since the discharge rack has no power input and is in a driven free state, when the speed of the subsequent process of pulling the bag making raw film changes, the tension of the raw film on the discharge rack will also change accordingly, affecting the normal operation of the bag making machine; 3. When the bag making raw film deviates during the discharge process, the existing discharge rack cannot effectively and promptly correct the deviation, which will also affect the normal operation of the bag making machine. To address this situation, we have proposed a three-side sealing bag making machine barrel material discharge rack. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned shortcomings and provide a tube material unloading stand for a three-side sealing bag making machine. It is convenient to replace the raw material film for bag making, which not only saves time and effort, but also effectively avoids the waste of raw material film. During the bag making process, the unloading speed of the unloading stand can be controlled to ensure the tension of the raw material film. It can also effectively correct the deviation of the raw material film during the conveying process, effectively ensuring the normal operation of the bag making machine.

[0005] The technical solutions adopted by the present invention to solve the above technical problems are as follows:

[0006] The barrel material unloading rack of the three-side sealing bag making machine includes a base frame, a placement rack, a cylinder, a discharging roller, a guide rod, a speed detector, a magnetic powder brake, a metal detector, an infrared probe and a control cabinet. The base frame is respectively provided with a discharge hole at the top and the bottom. The base frame is provided with an upper base and a lower base. The upper base and the lower base are respectively provided with a pair of slide rails. The paired placement racks are respectively slidably mounted on the paired slide rails on the upper base and the lower base through the paired slide grooves opened at the bottom. The paired cylinders are respectively fixedly mounted on the outer side walls of the upper base and the lower base. The front ends of the telescopic rods of the paired cylinders are respectively fixedly connected to the paired placement racks. The discharging roller and multiple guide rods are respectively rotatably mounted on the upper base and the lower base, and the guide rod is located at the rear of the discharging roller. The paired speed detectors are respectively fixedly mounted on the upper On the base and the lower base, the front detection heads of the paired speed detectors are respectively in contact with the corresponding guide rods, and the paired discharge rollers are respectively fixedly installed with a first gear at one end, and the first gear is located on the outside of the upper base and the lower base, and the first gear and the speed detector are located on the same side, and the paired magnetic powder brakes are respectively fixedly installed on the outside of the upper base and the lower base, and the paired magnetic powder brakes are respectively engaged with the first gear on the paired discharge rollers through the second gear on the rotating shaft, and the speed detector and the magnetic powder brake are electrically connected through the controller, and the paired metal detectors and infrared probes are respectively fixedly installed on the base frame through supports and are located on the rear side of the guide rod, and the control cabinet is fixedly installed on the base frame, and the control cabinet is respectively controlled and connected with the paired cylinders, metal detectors, controllers and infrared probes.

[0007] Preferably, a plurality of the guide rods are distributed in rows.

[0008] Preferably, the upper base and the lower base are vertically distributed on the base frame.

[0009] Preferably, the metal detector and the infrared probe are respectively located above the discharge hole of the base frame.

[0010] The beneficial effects that can be achieved by the above technical solutions of the present invention are:

[0011] 1. By setting up a metal detector and an infrared probe, the infrared probe can be used to detect whether there is raw material film passing by at any time. The metal detector can also be used to detect metal spokes on the bag-making raw material film. When metal spokes are detected, the control cabinet controls the bag-making machine to stop, and the unloading roller stops rotating at the same time to prevent the end of the raw material film from separating from the barrel shaft, thereby facilitating the replacement of the cylindrical raw material film. This not only saves time and effort, but also effectively avoids the waste of raw material film. The metal detector and infrared probe are set at the same time, which has a double insurance function.

[0012] 2. By setting up components such as speed detectors, controllers and magnetic powder brakes, the unloading speed of the unloading rack can be constantly limited, so that the raw film is always in a certain tension state during the conveying process, thereby ensuring the normal operation of the bag making machine;

[0013] 3. By setting up components such as cylinders and slide rails, when the raw material film deviates to one side during the conveying process, workers can effectively fine-tune the placement rack by adjusting the cylinder to correct the deviation of the bag-making raw material film and ensure the normal operation of the bag-making machine.
