[0004] However, when the above technology is used, it is easy to cause waste when adding materials, and the feeding efficiency is relatively low. Utility Model Content

[0005] The purpose of the present utility model is to provide an automatic feeding structure for a bag packaging machine to solve the problems raised by the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] 7. The swiftly and minutely adjusting device for a wood-planer working table as claimed in claim 1, wherein said linking rod and said adjusting base are pivotally connected to each other with a bolt, and said bolt has a round shank to contact with said linking rod. said linking rod has a round shank to contact with said linking rod.

[0008] Preferably, the output end of the motor is fixedly connected to an active roller, the surface of the active roller is transmission-connected to a conveyor belt, the inner side of one end of the conveyor belt is transmission-connected to a driven roller, and one end of the active roller and both ends of the driven roller are rotationally connected to the surface of the movable frame.

[0009] Preferably, a plurality of clamping plates are fixedly connected to the surface of the conveyor belt, and a plurality of clamping blocks are fixedly connected to the surface of the clamping plates.

[0010] Preferably, a feeding pipe is fixedly connected to the top of the feeding rack, and a feeding branch pipe is fixedly connected to the bottom of the feeding pipe.

[0011] Preferably, a branch pipe is fixedly connected to the surface of the feeding branch pipe, and one end of the branch pipe is fixedly passed through and extends to the outside of the feeding box.

[0012] Preferably, a support column is fixedly connected to the bottom of the fixing frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] When the utility model is in use, two packaging bags are placed between the clamping blocks tightly against the clamping blocks. At this time, the packaging bags are located just above the two branch pipes. The materials are then input through the feeding pipe, and then transported to the branch pipe through the feeding branch pipe, and finally transported into the packaging bag through the branch pipe. As the materials are added into the packaging bag, the gravity increases, which will drive the conveyor belt to move downward. The downward movement of the conveyor belt will drive the active roller and the driven roller to move downward, thereby driving the two movable racks to move downward. The downward movement of the movable rack drives the connecting plate and the metal connecting plate to move downward, thereby compressing the spring to ensure stable downward movement. As more and more materials are added, when the packaging bag is full, the first moving contact will also contact the first static contact, thereby connecting the circuit between the electric telescopic rod and the motor and the external power supply, thereby starting the electric telescopic rod and the motor, and the electric telescopic rod will extend, thereby driving the L-shaped baffle to move toward the bottom of the branch pipe until the bottom of the branch pipe is completely blocked to avoid waste. At the same time, the motor will drive the active roller to rotate. The active roller will drive the conveyor belt to rotate, thereby conveying the loaded packaging bag through the conveyor belt to the next process. When the loading of the current packaging bag is completed, since the distance between the clamping structure between the upper side and the left and right sides is the same, and the distance between the clamping structure between the lower side and the left and right sides is the same, as the packaging bag in the upper clamping structure is conveyed to the right, the clamping structure on the left moves to the right until the packaging bag in the upper clamping structure moves to the far right, the packaging bag that has been loaded is removed, and the clamping structure on the left is just located directly below the branch pipe. As the weight decreases, the spring will drive the movable frame and the conveyor belt to return to their original positions under its own elastic action, thereby disconnecting the circuit between the motor and the external power supply and stopping the transmission of the conveyor belt. However, the second moving contact will contact the second static contact, thereby driving the electric telescopic rod to retract to its original state, thereby driving the L-shaped baffle to move away from the bottom of the branch pipe to load the next packaging bag, and repeating this process to solve the problem of easy waste and low loading efficiency.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-7The utility model provides a technical solution: an automatic feeding structure for a bag packaging machine, comprising a feeding frame 1, two fixed frames 2 and two movable frames 4, one side of the feeding frame 1 is fixedly connected to two electric telescopic rods 8, one end of the electric telescopic rod 8 is fixedly connected to an L-shaped baffle 9, the surface of the fixed frame 2 is provided with two slide grooves 13, the inner side of the slide groove 13 is fixedly connected to a spring 14, the surface of the fixed frame 2 is fixedly connected to a first static contact 16, one of the fixed frames 2 is fixedly connected to a second metal contact plate 23, the bottom of the second metal contact plate 23 is fixedly connected to a second static contact 24, the surface of the movable frame 4 is fixedly connected to two connecting plates 15, the surface of the connecting plate 15 is fixedly connected to a first metal contact plate 17, the bottom of the first metal contact plate 17 is fixedly connected to a first moving contact 18, one of the first metal contact plates A second moving contact 22 is fixedly connected to the top of 17, and a motor 12 is fixedly connected to the surface of one of the movable frames 4, one of the first moving contacts 18 and the first static contact 16 is electrically connected to the electric telescopic rod 8, the second moving contact 22 and the second static contact 24 are also electrically connected to the electric telescopic rod 8, and the other first moving contact 18 and the first static contact 16 are electrically connected to the motor 12. The current electric telescopic rod 8 is in its original state and cannot be extended. As the material increases, it will drive the movable frame 4 to move downward, and at the same time, the compression spring 14 will be compressed. The movable frame 4 moves downward and drives the first moving contact 18 to move downward until it contacts the first static contact 16, thereby connecting the circuit between the electric telescopic rod 8, the motor 12 and the external power supply, thereby starting the extension of the electric telescopic rod 8 and the motor 12, and the electric telescopic rod 8 will drive the L-shaped baffle 9 to move.

[0025] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the output end of the motor 12 is fixedly connected to the active roller 19, the surface of the active roller 19 is connected to the conveyor belt 21, and the inner side of one end of the conveyor belt 21 is connected to the driven roller 20. One end of the active roller 19 and both ends of the driven roller are rotatably connected to the surface of the movable frame 4. A plurality of clamps 10 are fixedly connected to the surface of the conveyor belt 21, and a plurality of clamping blocks 11 are fixedly connected to the surface of the clamping plates 10. The packaging bag is placed between the clamping blocks 11 and the clamping blocks 11. When the current packaging bag is full, as the circuit of the motor 12 and the external power supply is connected, the motor 12 will drive the active roller 19 to rotate, and the active roller 19 will drive the conveyor belt 21 to rotate. The clamping structure 10 and the clamping block 11 form a clamping structure. The distance between the clamping structure on the upper side and the left and right sides is the same, and the distance between the clamping structure on the lower side and the left and right sides is the same. Therefore, as the packaging bag in the upper clamping structure is conveyed to the right, the clamping structure on the left side moves to the right until the packaging bag in the upper clamping structure moves to the far right. The packaging bag that has been filled is removed, and the clamping structure on the left side is just below the branch pipe 7, so that the packaging bag behind can be filled. This reciprocating process makes filling convenient and improves the filling efficiency.

[0026] like Figure 1 and Figure 6 As shown, a feeding pipe 5 is fixedly connected to the top of the feeding rack 1, a feeding branch pipe 6 is fixedly connected to the bottom of the feeding pipe 5, a branch pipe 7 is fixedly connected to the surface of the feeding branch pipe 6, one end of the branch pipe 7 is fixedly passed through and extends to the outside of the feeding box, the material is input through the feeding pipe 5, and then transported to the branch pipe 7 through the feeding branch pipe 6, and finally transported to the packaging bag through the branch pipe 7.

[0027] like Figure 1 As shown, a support column 3 is fixedly connected to the bottom of the fixing frame 2 to support and fix the fixing frame 2.

[0028] Working principle: When in use, two packaging bags are placed between the clamping blocks 11, with the packaging bags located directly above the two branch pipes 7. Then, the material is fed into the feeding pipe 5, then transported to the branch pipe 7 through the feeding branch pipe 6, and finally transported into the packaging bags through the branch pipe 7.

[0029] As materials are added into the packaging bag, gravity increases, which will drive the conveyor belt 21 to move downward. The downward movement of the conveyor belt 21 will drive the active roller 19 and the driven roller 20 to move downward, thereby driving the two movable frames 4 to move downward. The downward movement of the movable frame 4 drives the connecting plate 15 and the metal connecting plate 15 to move downward, thereby compressing the spring 14 to ensure stable downward movement. As more and more materials are added, when the packaging bag is full, the first moving contact 18 will also contact the first static contact 16, thereby connecting the circuit between the electric telescopic rod 8 and the motor 12 and the external power supply, thereby starting the electric telescopic rod 8 and the motor 12, and the electric telescopic rod 8 will extend, thereby driving the L-shaped baffle 9 to move toward the bottom of the branch pipe 7 until the bottom of the branch pipe 7 is completely blocked to avoid waste;

[0030] At the same time, the motor 12 will drive the active roller 19 to rotate, and the active roller 19 will drive the conveyor belt 21 to rotate, so that the packaging bag with the added material is conveyed to the next process through the conveyor belt 21;

[0031] When the current packaging bag is loaded, since the distances between the upper side and the clamping structures on the left and right sides are the same, and the distances between the lower side and the clamping structures on the left and right sides are the same, as the packaging bag in the upper clamping structure is conveyed to the right, the clamping structure on the left side moves to the right, until the packaging bag in the upper clamping structure moves to the rightmost side, the loaded packaging bag is removed, and the clamping structure on the left side is just located under the branch pipe 7. As the weight decreases, the spring 14 will drive the movable frame 4 and the conveyor belt 21 to return to their original positions under its own elastic action, thereby disconnecting the circuit between the motor 12 and the external power supply, and stopping the conveying of the conveyor belt 21;

[0032] However, the second moving contact 22 will contact the second static contact 24, thereby driving the electric telescopic rod 8 to retract to its original state, thereby driving the L-shaped baffle 9 to move away from the bottom of the branch pipe 7 to add the next packaging bag, and so on.

[0033] The above operations can improve the feeding efficiency and reduce the waste of materials.

[0034] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include," "comprise," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, material, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or includes elements inherent to such process, method, material, or apparatus.

[0035] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
