Description

Technical Field

[0001] This invention relates to the field of packaging bag unpacking devices, and more particularly to a packaging bag rotating device. Background Technology

[0002] In the pharmaceutical manufacturing industry, raw materials used to produce drugs are usually stored in packaging bags. During drug manufacturing, these bags need to be cut to allow the materials to be poured into the production equipment. With the continuous development of society, pharmaceutical equipment has achieved fully automated operation. However, when cutting and unpacking the packaging bags, because drug raw material packaging bags usually use double-layer packaging with an inner bag and an outer bag, and the inner bag can slide inside the outer bag, cutting and unpacking the outer bag can easily damage the inner liner, causing the raw materials to leak. Therefore, a device that can drive the packaging bag to rotate is needed so that when the cutting blade cuts the outer bag, it slides the inner bag away from the cutting blade, preventing the cutting blade from damaging the inner bag. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by providing a packaging bag rotating device.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0005] A packaging bag rotating device includes a frame, on which a conveying assembly is rotatably mounted. The conveying assembly is driven to rotate by a transmission assembly mounted on the frame. The conveying assembly includes a rotating frame rotatably mounted on the frame. A conveyor is mounted on the rotating frame, and a pressing assembly is mounted on the rotating frame for pressing the packaging bag.

[0006] Preferably, the pressing assembly includes a fixed frame fixedly mounted on the rotating frame, a first cylinder fixedly mounted on the fixed frame, a pressure plate fixedly mounted on the movable end of the first cylinder, and the pressure plate being located above the conveyor for pressing the packaging bag.

[0007] Preferably, the pressure plate has a triangular structure, with the tip of the pressure plate facing one side of the conveyor.

[0008] Preferably, the transmission assembly includes a drive motor, which is fixedly mounted on the frame, and the output shaft of the drive motor is fixedly connected to one side of the rotating frame for driving the rotating frame to rotate.

[0009] Preferably, a positioning plate is fixedly mounted on the frame, a position sensor is fixedly mounted on the positioning plate, a rotating shaft is fixedly mounted on one side of the rotating frame, the rotating shaft is rotatably mounted on the positioning plate, the rotating shaft and the output shaft of the drive motor are coaxially arranged, and a limit strip is fixedly mounted on the rotating shaft.

[0010] Preferably, a second cylinder is fixedly installed on both sides of the rotating frame, and a first baffle is fixedly connected to the movable end of the second cylinder. The first baffle is located on both sides of the conveyor and is used for adjusting the position of the packaging bag.

[0011] Preferably, a fixing rod is fixedly installed at both ends of the rotating frame, a third cylinder is fixedly installed on the fixing rod, and a second baffle is fixedly connected to the movable end of the third cylinder. The second baffle slides vertically on both sides of the conveyor.

[0012] Preferably, a slide rail is fixedly mounted on the fixed rod, and a slider is fixedly mounted on the second baffle, the slider being slidably mounted on the slide rail.

[0013] Preferably, the conveyor is a belt conveyor.

[0014] The beneficial effects of adopting the above technical solution are as follows:

[0015] In this invention, when the packaging bag is cut, the packaging bag is conveyed on a conveyor. The pressure plate can press the packaging bag tightly onto the conveyor. Then, the rotating frame drives the packaging bag to rotate to a certain angle. After the pressure plate is released, the inner bag can slide to the bottom of the outer bag. Then, the cutting blade cuts the outer bag. After the cutting is completed, the pressure plate squeezes the packaging bag. The rotating frame drives the packaging bag to rotate in the opposite direction. After the pressure plate is released, the inner bag can slide from the cut of the outer bag to the outside, completing the cutting of the packaging bag and avoiding damage to the inner bag by the cutting blade.

Detailed Implementation

[0021] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0022] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] like Figures 1 to 4As shown, a packaging bag rotating device includes a frame 1, which can be fixedly installed on the ground. A conveying component is rotatably installed on the frame 1. The conveying component can rotate clockwise and counterclockwise on the frame 1. The conveying component is driven to rotate by a transmission component installed on the frame 1. The conveying component includes a rotating frame 2, which is rotatably installed on the frame 1. The rotating frame 2 is connected to the transmission component for driving the rotating frame 2 to rotate. A conveyor 3 is installed on the rotating frame 2 for conveying the packaging bag. A pressing component is installed on the rotating frame 2 for pressing the packaging bag. In this invention, when cutting a packaging bag containing an inner bag, the packaging bag is conveyed on a conveyor 3. When it reaches the middle of the conveyor 3, a clamping assembly presses the packaging bag firmly onto the conveyor 3. Subsequently, a transmission assembly drives a rotating frame 2 to rotate, preventing the packaging bag from slipping off if the conveyor 3 tilts. When the rotating frame 2 rotates to a certain angle, a mechanical gripper clamps and fixes the outer bag on the upper side of the packaging bag. The mechanical gripper can be commercially available equipment, which will not be described in detail here. After the clamping assembly is released, the inner bag can slide to the bottom of the outer bag, and the cutting blade horizontally cuts the outer bag of the packaging bag. The cutting is performed on the upper part of the packaging bag. After cutting, the clamping component presses the packaging bag firmly, the mechanical claw releases the packaging bag, and the rotating frame 2 rotates in the opposite direction. When the rotating frame 2 tilts to a certain angle, the mechanical claw clamps the other end of the outer bag of the packaging bag. As the clamping component is released, the inner bag slides down from the outer bag of the packaging bag and finally slides out of the outer bag from the cut. This completes the cutting and unpacking of the outer bag of the packaging bag. During the unpacking process, the rotation of the rotating frame 2 effectively prevents the inner bag from being cut by the cutting blade, thus protecting the inner bag.

[0025] In one embodiment of the present invention, the pressing assembly includes a fixed frame 4 fixedly mounted on the rotating frame 2, a first cylinder 5 fixedly mounted on the fixed frame 4, and a pressure plate 6 fixedly mounted on the movable end of the first cylinder 5. The pressure plate 6 is located above the conveyor 3 and is used to press the packaging bag. In this embodiment, when the packaging bag is conveyed to the conveyor 3, the piston rod of the first cylinder 5 extends downward, driving the pressure plate 6 to move downward until it contacts the packaging bag, pressing and fixing the packaging bag on the conveyor 3, so that the packaging bag is prevented from slipping off the conveyor 3 after the conveyor 3 rotates and tilts to a certain angle.

[0026] In one embodiment of the present invention, the pressure plate 6 has a triangular structure, with the tip of the pressure plate 6 facing one side of the conveyor 3. Since the raw materials used to produce drugs are generally in powder or granular form, when the pressure plate 6 is a flat plate, the extrusion force is insufficient to fix the packaging bag on the conveyor 3, which may cause the packaging bag to slide during the rotation of the conveyor 3. In this embodiment, the pressure plate 6 has a triangular structure, with the tip of the pressure plate 6 facing one side of the conveyor 3. Therefore, when the packaging bag is squeezed, the tip of the pressure plate 6 can squeeze the material, preventing the packaging bag from sliding on the conveyor 3.

[0027] In one embodiment of the present invention, the transmission assembly includes a drive motor 7, which is a servo motor capable of precisely controlling the rotation angle and rotation speed. The drive motor 7 is fixedly mounted on the frame 1, and its output shaft is fixedly connected to one side of the rotating frame 2 for driving the rotating frame 2 to rotate. In this embodiment, the drive motor 7 can drive the rotating frame 2 to rotate, thereby causing the conveyor 3 and the packaging bags on the conveyor 3 to rotate, thus completing the rotation of the packaging bags.

[0028] In one embodiment of the present invention, a positioning plate 8 is fixedly mounted on the frame 1. The positioning plate 8 is located on the side of the frame 1 opposite to the drive motor 7. A position sensor 9 is fixedly mounted on the positioning plate 8. There are two position sensors 9, which are symmetrically arranged. A rotating shaft 10 is fixedly mounted on one side of the rotating frame 2. The rotating shaft 10 is rotatably mounted on the positioning plate 8. The rotating shaft 10 and the output shaft of the drive motor 7 are coaxially arranged. A limit strip 11 is fixedly mounted on the rotating shaft 10. In this embodiment, when the drive motor 7 drives the rotating frame 2 to rotate, the rotating shaft 10 and the limit strip 11 rotate synchronously. When the limit strip 11 blocks the sensing end of the position sensor 9, the drive motor 7 stops working, the rotating frame 2 stops rotating, and the rotating frame 2 is in an inclined state. Similarly, when the rotating frame 2 rotates in the opposite direction, and the limit strip 11 blocks the sensing end of the other position sensor 9, the drive motor 7 stops working, and the rotating frame 2 is in the opposite inclined state.

[0029] It should be noted that the positioning plate 8 has a positioning groove 19, which is an arc-shaped structure. The positioning groove 19 is coaxially arranged with the rotating shaft 10 and is located above the rotating shaft 10. Two position sensors 9 are slidably arranged in the positioning groove 19 and are symmetrically arranged. By adjusting the position of the two sensors 9 in the positioning groove 19, the tilt angle of the rotating frame 2 can be adjusted.

[0030] In one embodiment of the present invention, two second cylinders 12 are fixedly arranged on both sides of the rotating frame 2. Each side of the rotating frame 2 is provided with two second cylinders 12. The second cylinders 12 are arranged horizontally, so the movable end of the second cylinder 12 extends and retracts in the horizontal direction. The movable end of the second cylinder 12 is fixedly connected to a first baffle 13. The first baffle 13 is located on both sides of the conveyor 3. In this embodiment, when the packaging bag is conveyed to the conveyor 3, the movable end of the second cylinder 12 extends, driving the first baffles 13 on both sides of the rotating frame 2 to move towards each other, clamping the packaging bag, so that the packaging bag can be pushed to the middle position of the conveyor 3, which facilitates the subsequent pressing and fixing of the packaging bag.

[0031] In one embodiment of the present invention, fixed rods 14 are fixedly provided at the front and rear ends of the rotating frame 2. The fixed rods 14 are vertically arranged, and a third cylinder 15 is fixedly provided on the fixed rods 14. The movable end of the third cylinder 15 extends and retracts in the vertical direction. The movable end of the third cylinder 15 is fixedly connected to a second baffle 16. The second baffle 16 slides vertically on the front and rear sides of the conveyor 3. In this embodiment, the extension and retraction of the movable end of the third cylinder 15 can drive the second baffle 16 to slide in the vertical direction, thereby blocking the packaging bags on the conveyor 3 and preventing the packaging bags from falling when the conveyor 3 is tilted.

[0032] In one embodiment of the present invention, a slide rail 17 is fixedly provided on the fixed rod 14, and a slider 18 is fixedly provided on the second baffle 16. The slider 18 is slidably disposed on the slide rail 17, so that the second baffle 16 is more stable during the sliding process.

[0033] Furthermore, conveyor 3 is a belt conveyor.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
