Description

Technical Field

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

[0002] In the modern material handling and packaging industry, ton bag machines (also known as bulk bag packaging machines or ton bag packaging machines) are an important type of packaging equipment widely used in fertilizers, chemicals, building materials, grains, and other fields. They are used for the automatic or semi-automatic packaging of powdery, granular, or lumpy materials into large bags (ton bags). During the use of ton bag machines, the bag dropping device safely and smoothly transfers the full-filled bags (ton bags) from the packaging position to the next processing stage (such as conveyor belts, stacking areas, etc.). Existing bag dropping devices are generally directly opened, and the bags fall directly after reaching the dropping device. This can easily lead to inconsistent bag placement, resulting in uneven stacking of bags and affecting subsequent loading. Utility Model Content

[0003] The purpose of this utility model is to provide a bag dropping device for a ton bag machine, so as to solve the problem mentioned in the background art that the existing bag dropping devices are generally directly opened, and the bags fall directly after arriving at the bag dropping device, which easily leads to inconsistent positions of the bags falling, resulting in uneven stacking of bags and affecting the later loading of bags.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a ton bag unloading device, comprising: a mounting frame, wherein a rotating roller and a driving component for driving the rotating roller to rotate are provided on the mounting frame, and a baffle is provided on the rotating roller;

[0005] The mounting frame is equipped with a detector, and the driving component is used to drive the rotating roller and the baffle to rotate downward when the detector detects that the material bag has reached the predetermined position of the baffle.

[0006] Preferably, there are two rollers and two baffles, with the two baffles respectively located on the side wall of the two rollers that are close to each other, and the two rollers are rotatably mounted on the mounting frame.

[0007] Preferably, the driving component includes a transmission mechanism and a drive motor for driving the transmission mechanism to rotate, the transmission mechanism being mounted on a mounting frame and connected to the shafts of the two rotating rollers.

[0008] Preferably, the detector includes a mounting plate, a flipping component, and a sensor. The mounting plate is mounted on a mounting frame, the flipping component is hinged to the mounting plate, the flipping component is V-shaped, one end of the flipping component extends between two baffles, and the sensor is located on the other end of the flipping component.

[0009] Preferably, the unloading device further includes a protective cover for covering the mounting frame, with an opening on one side and guide plates located around the opening on the cover.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by detecting the position of the material bag by the detector, after the material bag reaches the predetermined area, the driving component drives the rotating roller and the baffle to rotate downward, so that the material bag falls off the baffle, ensuring that the area where the material bag falls is consistent, making the material bag stacked neatly, which is convenient for subsequent loading.

[0015] 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.

[0016] Example 1

[0017] Please see Figure 2 and Figure 3 A ton bag unloading device includes: a mounting frame 4, on which two rotating rollers 5 are rotatably mounted, and baffles 6 are provided on the side walls of the two rotating rollers 5 that are close to each other. A driving component 7 is mounted on the mounting frame 4. The driving component 7 includes a transmission mechanism 71 (the transmission mechanism 71 includes a mounting box and two gears rotatably mounted inside the mounting box, the two gears meshing with each other, and the shafts of the two gears are respectively connected to the shafts of the two rotating rollers 5) and a drive motor 72 (the drive motor 72 is a servo motor, and the output shaft of the servo motor is connected to the shaft of one of the gears). The transmission mechanism 71 is mounted on the mounting frame 4, and the drive motor 72 is mounted on the transmission mechanism 71. A detector 8 is provided on the mounting frame 4.

[0018] It should be noted that when the external conveying equipment conveys the material bag to the two baffles 6, the detector 8 detects that there is a material bag on the baffle 6 and the material bag has reached the predetermined area. Then, the drive unit 7 is activated to drive the rotating roller 5 to rotate (the drive motor 72 is activated, causing the transmission mechanism 71 to rotate the two rotating rollers 5). This causes the two baffles 6 to rotate downwards, so that the material bag falls between the two baffles 6. Then, the drive unit 7 drives the rotating roller 5 to rotate in the opposite direction, so that the two baffles 6 are reset. The operation is repeated to complete the stacking of the material bag.

[0019] It should also be noted that the package dropping device is equipped with a central control device (such as a central control host, which is existing technology and will not be described in detail here) to receive information from the detector 8 and to control the operation of the drive unit 7.

[0020] In this embodiment, as a further optimization, please refer to... Figure 3 The detector 8 includes a mounting plate 83, a flip-up component 81, and a sensor 82. The mounting plate 83 is located on the top wall of the mounting bracket 4. The flip-up component 81 is hinged to the top wall of the mounting plate 83. The flip-up component 81 is V-shaped (the flip-up component 81 is a V-shaped block), with its pointed corners facing upwards. One end of the flip-up component 81 extends between the two baffles 6. The sensor 82 is located on the other end of the flip-up component 81 (the sensor 82 can be a proximity sensor, with its transmitting end mounted on the flip-up component 81 and its receiving end mounted on the mounting plate). (Above 83); When the material bag is fed onto the two baffles 6, the material bag applies pressure to one end of the flipping part 81, causing the flipping part 81 to rotate on the top of the mounting plate 83 and move the transmitting end of the sensor 82 until the transmitting end is aligned with the receiving end. At this time, the detection signal emitted by the transmitting end is received by the receiving end, and the drive motor 72 is controlled to work, causing the transmission mechanism 71 to rotate the two rotating rollers 5, causing the two baffles 6 to rotate downwards, so that the material bag falls from the two baffles 6. The dropping device is only activated after the material bag reaches the appropriate position, ensuring accurate material feeding.

[0021] It should be noted that a spring is installed between the mounting plate 83 and the flipping component 81, which supports the flipping component 81 and prevents it from rotating automatically.

[0022] In this embodiment, as a further optimization, please refer to... Figure 1 and Figure 2 The bag-dropping device also includes a protective cover 1, which covers the mounting frame 4. The rotating roller 5, baffle 6, drive unit 7, and detector 8 are all located inside the protective cover 1. The bottom of the protective cover 1 is open, and an opening 2 is provided on one side of the protective cover 1. Guide plates 3 are provided on the protective cover 1 around the opening 2. The bag enters the interior of the protective cover 1 through the opening 2 and falls above the two baffles 6.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
