Description

Technical Field

[0001] This utility model belongs to the field of packaging machine technology, and specifically relates to a packaging machine feeding device. Background Technology

[0002] Packaging machines are equipment used to package products. They are widely used in food, chemical, pharmaceutical and daily chemical industries. The feeding device of a packaging machine is a key component in the packaging process. The feeding device is usually used to transport raw materials from storage or processing areas to the packaging machine for further processing or packaging. It is suitable for situations where raw materials need to be measured and packaged according to certain specifications or quantities, ensuring accurate input of raw materials and continuity of production, thereby greatly improving production efficiency.

[0003] The patent with publication number CN222539150U describes a feeding device for a packaging machine. It works by impacting two buffer plates as the raw material falls, causing them to rotate downwards and rebound in combination with the elasticity of springs, thereby achieving the effect of shaking the material and removing dust and impurities. However, this structure is affected by external factors such as the flow rate, particle size, weight, and falling height of the raw material. It is a passive shaking material that is difficult to control, and the shaking effect and stability are poor. Utility Model Content

[0004] The purpose of this invention is to provide a material feeding device for a packaging machine. By rotating the annular plate, the two lifting plates move synchronously and reciprocally. The movement is regular and the force is uniform. This converts the passive material vibration in the original patent into active material lifting. It is not affected by external factors such as raw material flow rate, particle size, weight, and drop height, and the lifting effect and stability are better.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A packaging machine feeding device includes lifting plates symmetrically and rotatably installed inside a material box. A chute is provided on one side of the lifting plate, and a through groove is provided at the bottom of the chute. Annular plates matching the number of lifting plates are rotatably provided on the inner side wall of the material box. Support rods are fixedly connected to the side walls of the annular plates, and rollers are rotatably connected to one end of the support rods for sliding matching with the chute. Two annular plates are arranged diagonally, and two support rods are mirror images of each other. A mechanical transmission mechanism is provided on the outside of the material box for driving the annular plates to rotate.

[0007] The material box has fixed unloading ports at both the top and bottom, and the lifting plates are distributed diagonally in a mirror image.

[0008] The mechanical transmission mechanism includes a cover plate fixedly connected to the inner wall of the annular plate. The center of the cover plate corresponds to the geometric center of the lifting plate, and a rotating shaft is fixedly connected to its center.

[0009] The rotating shaft is rotatably connected to the side wall of the material box, and a groove is provided on one side of the inner wall of the material box for fitting and matching with the annular plate.

[0010] The rotating shaft is fixedly connected to a pulley at one end outside the material box, and the two pulleys are connected by belt drive.

[0011] A variable frequency motor is fixedly assembled on the outer wall of the material box, and the output end of the variable frequency motor is connected to one of the rotating shafts.

[0012] The material box is provided with an air duct on the outside. The air duct is connected to the material box through filter exhaust ports at both ends, and the filter exhaust ports are located between the two lifting plates.

[0013] The technical effect achieved by this utility model is as follows: the rotation of the ring plate drives the two lifting plates to reciprocate synchronously, with regular motion and uniform force, which transforms the passive vibration of the original patent into active lifting. It is not affected by external factors such as raw material flow rate, particle size, weight, and falling height, and the lifting effect and stability are better. Attached Figure Description

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-4 As shown, a packaging machine feeding device includes lifting plates 102 that are symmetrically rotated and installed inside the material box 1.

[0022] The material box 1 is equipped with a mechanical transmission mechanism on its exterior for driving the annular plate 106 to rotate. The mechanical transmission mechanism includes a cover plate 105 fixedly connected to the inner wall of the annular plate 106. The center of the cover plate 105 corresponds to the geometric center of the lifting plate 102, and a rotating shaft 109 is fixedly connected to its center. The rotating shaft 109 is rotatably connected to the side wall of the material box 1. A groove 113 is provided on one side of the inner wall of the material box 1 for fitting and matching with the annular plate 106. A pulley 110 is fixedly connected to one end of the rotating shaft 109 located outside the material box 1. The two pulleys 110 are connected by a belt 111. A variable frequency motor 112 is fixedly assembled on the outer wall of the material box 1. The output end of the variable frequency motor 112 is connected to one of the rotating shafts 109.

[0023] According to the above structure, the variable frequency motor 112 is started to drive a rotating shaft 109 to rotate. The rotating shaft 109 drives another rotating shaft 109 and its pulley 110 to rotate synchronously through the pulley 110 and belt 111. When the rotating shaft 109 rotates, it drives the cover plate 105 to rotate. The cover plate 105 drives the annular plate 106 to rotate. The variable frequency motor 112 can change the frequency and voltage of the input power supply through its internal frequency converter to adjust the speed, thereby controlling the rotation speed of the cover plate 105.

[0024] Furthermore, the annular plate 106 is fitted into the groove 113, with its edge fitting against the edge of the groove 113. At the same time, the cover plate 105 and the annular plate 106 together form an integrated barrier, both of which prevent raw materials from leaking into the back of the cover plate 105 and causing rotational jamming. It should be noted that, in order to clearly show the connection relationship between the pulley 110 and the belt 111, the protective shell used for dust protection of both is not shown in the attached drawings. In actual manufacturing and installation, the protective shell should be installed according to the actual size and industry standards, and should not be regarded as a technical defect of this patent.

[0025] See attached document Figures 1-4The material box 1 has a fixed unloading port 101 at both the top and bottom. The lifting plates 102 are diagonally mirrored. A chute 103 is provided on one side of the lifting plate 102. A through groove 104 is provided through the bottom of the chute 103. The inner side wall of the material box 1 is rotatably provided with annular plates 106 matching the number of lifting plates 102. A support rod 107 is fixedly connected to the side wall of the annular plate 106. A roller 108 is rotatably connected to one end of the support rod 107 for sliding matching with the chute 103. The two annular plates 106 are diagonally arranged, and the two support rods 107 are mirrored. The outer side of the material box 1 is provided with an air duct 115. The air duct 115 is connected to the material box 1 through the filter exhaust ports 114 at both ends, and the filter exhaust ports 114 are located between the two lifting plates 102.

[0026] According to the above structure, the unloading port 101 is located on the opposite right side of both ends of the material box 1, and is used for receiving and discharging materials respectively. The annular plate 106 is located at the diagonal position (upper right and lower left) inside the material box 1. The positions of the support rods 107 on the two annular plates 106 are mirror images of each other (one on the left side of the annular plate 106 and the other on the right side). When the annular plate 106 rotates counterclockwise, the support rod 107 on the left side is pushed downward along the tangent direction of the annular plate 106. The roller 108 is inserted into the groove 103 of the lifting plate 102, pushing the upper lifting plate 102 to slide downward, and the raw material is pushed to the middle of the material box 1.

[0027] Furthermore, the right-side support rod 107 is pulled upward along the tangent of the annular plate 106, and the roller 108 is inserted into the groove 103 of the lifting plate 102, pulling the lower lifting plate 102 to slide upward and catch the falling material. When the lower lifting plate 102 rotates downward, the material is discharged by the discharge port 101 at the bottom of the feeding box 1. The through groove 104 at the bottom of the groove 103 facilitates the leakage of material particles after they accidentally enter the groove 103, preventing obstruction of the movement of the roller 108. At the same time, the leaked material can fall back into the feeding box 1 by its own weight.

[0028] Furthermore, the duct 115 is connected to an external exhaust fan. The airflow is drawn into the material box 1 through the duct 115 and the filter exhaust port 114. During the process of the raw material being lifted and shaken off by the lifting plate 102, the dust particles in it are sucked up. The filter exhaust port 114 is equipped with a filter screen on the side to prevent the raw material from being sucked in.

[0029] The working principle of this utility model is as follows: the variable frequency motor 112 is started to drive a rotating shaft 109 to rotate. The rotating shaft 109 drives another rotating shaft 109 and the pulley 110 to rotate synchronously through the pulley 110 and belt 111. When the rotating shaft 109 rotates, it drives the cover plate 105 to rotate. The cover plate 105 drives the annular plate 106 to rotate. The variable frequency motor 112 can change the frequency and voltage of the input power supply through its internal frequency converter to adjust the speed, thereby forming control over the rotation speed of the cover plate 105.

[0030] Furthermore, the annular plate 106 is fitted into the groove 113, with its edge fitting against the edge of the groove 113. At the same time, the cover plate 105 and the annular plate 106 together form an integrated barrier, which can prevent raw materials from leaking into the back of the cover plate 105 and causing rotational jamming. It should be noted that, in order to clearly show the connection relationship between the pulley 110 and the belt 111, the protective shell used to protect them from dust is not shown in the attached drawings. In actual manufacturing and installation, the protective shell should be installed according to the actual size and industry standards, and should not be regarded as a technical defect of this patent.

[0031] The receiving and unloading ports 101 are located on the opposite right sides of both ends of the material box 1, and are used for receiving and discharging materials respectively. The annular plates 106 are located at opposite corners (upper right and lower left) inside the material box 1. The positions of the support rods 107 on the two annular plates 106 are mirror images of each other (one on the left side of the annular plate 106 and the other on the right side). When the annular plate 106 rotates counterclockwise, the support rod 107 on the left side is pushed downward along the tangent of the annular plate 106. The roller 108 is inserted into the groove 103 of the lifting plate 102, pushing the upper lifting plate 102 to slide downward, and the raw material is pushed to the middle of the material box 1.

[0032] Furthermore, the right-side support rod 107 is pulled upward along the tangent of the annular plate 106, and the roller 108 is inserted into the groove 103 of the lifting plate 102, pulling the lower lifting plate 102 to slide upward and catch the falling material. When the lower lifting plate 102 rotates downward, the material is discharged by the discharge port 101 at the bottom of the feeding box 1. The through groove 104 at the bottom of the groove 103 facilitates the leakage of material particles after they accidentally enter the groove 103, preventing obstruction of the movement of the roller 108. At the same time, the leaked material can fall back into the feeding box 1 by its own weight.

[0033] Furthermore, the duct 115 is connected to an external exhaust fan. The airflow is drawn into the material box 1 through the duct 115 and the filter exhaust port 114. During the process of the raw material being lifted and shaken off by the lifting plate 102, the dust particles in it are sucked up. The filter exhaust port 114 is equipped with a filter screen on the side to prevent the raw material from being sucked in.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
