Description

Technical Field

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

[0002] In the food, pharmaceutical, and daily necessities manufacturing industries, packaging machines are the core equipment for achieving large-scale production. Their feeding accuracy, stability, and efficiency directly determine the capacity and product qualification rate of the packaging process. By accurately conveying the materials to be packaged to the sealing, filling, or forming stations of the packaging machine at a preset speed and quantity, the traditional manual feeding is replaced, significantly reducing labor costs and operational errors.

[0003] In the automatic feeding device of a packaging machine with patent number CN 222452760 U, although a brush is used to clean the surface of the passing items and the height of the brush is adjusted by a threaded rod to accommodate items of different heights, there are obvious limitations in actual operation: for items to be cleaned at different heights, the threaded rod needs to be manually rotated repeatedly to adjust the position of the brush. This is not only cumbersome and labor-intensive, but also requires pausing the feeding process for debugging, resulting in feeding interruption, reduced overall efficiency, and difficulty in meeting the needs of continuous and high-precision packaging production. Therefore, a new technical solution is proposed to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an automatic feeding device for packaging machines. This solves the technical problem that although the current feeding device cleans the surface of the items it passes through with a brush, the actual operation requires manual repeated rotation of the threaded rod to adjust the position of the brush. This is not only cumbersome and labor-intensive, but also requires pausing the feeding process for debugging, resulting in feeding interruption and reduced overall efficiency.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: an automatic feeding device for a packaging machine is designed, including a base. The surface of the base is provided with a first support frame and a second support frame. A fixed rod is fixedly connected between the inner side walls of the first support frame. Several movable rods are equidistantly rotatably connected to the surface of the fixed rod. An arc-shaped frame is fixedly connected to the side wall of the first support frame. A crossbar is slidably connected to the inner side of the arc-shaped frame. The two ends of the crossbar are respectively located inside the lifting frames on the front and rear sides. The lifting frames are fixedly connected to the mounting frame.

[0006] In this solution, when the items to be packaged are conveyed past, they naturally push the movable rod to rotate. The lower end of the movable rod then drives the crossbar to slide and rise along the arc-shaped frame. The mounting frame and the lifting frame are synchronously linked, which in turn drives the transmission rod and the surface brush to rise synchronously with the crossbar, achieving automatic adjustment of the brush height. The entire adjustment process requires no manual operation or electrical control system; it is completed solely through mechanical linkage. This not only reduces manual intervention costs but also avoids feeding interruptions, ensuring continuous feeding, while simplifying the structural design and reducing the difficulty of later maintenance.

[0007] Preferably, the front and rear side walls of the first support frame and the second support frame are provided with rectangular grooves, and a sliding rod is fixedly connected to the inner side of the rectangular groove. The two ends of the lifting frame are respectively penetrated by the sliding rods on the inner side of the first support frame and the second support frame, and the lifting frame is slidably connected to the sliding rods. A first spring is sleeved on the surface of the sliding rod below the lifting frame.

[0008] In practical applications, the lifting frame slides smoothly along the slide bar without deviating. The No. 1 spring assists in lifting and resetting, reducing the resistance of pushing the items, shortening the device cycle time, and improving feeding efficiency.

[0009] Preferably, the mounting frame is located inside the second support frame, and the front and rear ends of the mounting frame are fixedly connected to the lifting frames on the front and rear sides respectively. A transmission rod is rotatably connected to the inner side of the mounting frame, and the surface of the transmission rod is provided with bristles. A servo motor is fixedly connected to the outer wall of the mounting frame, and the tail end of the transmission shaft of the servo motor is connected to one end of the transmission rod.

[0010] In practical applications, the servo motor drives the brush to rotate and clean, and with the height adjustment of the mounting bracket, it can fit the surface of different items to remove impurities, ensuring the cleanliness of items before packaging and reducing manual cleaning costs.

[0011] Preferably, two extension plates are fixedly connected to the right side wall of the mounting bracket. The two extension plates are penetrated by a rotating rod and rotatably connected to the rotating rod. Cams are fixedly connected to both ends of the rotating rod, and a sensing plate is fixedly connected to the surface of the rotating rod between the two extension plates.

[0012] In practical applications, the rotation rod and cam can be triggered when an object touches the sensor plate. No additional electronic control components are required. The structure is simple and easy to maintain, avoiding operation interruptions caused by sensor failure.

[0013] Preferably, right-angle rods are fixedly connected to both the front and rear surfaces of the base, and several equidistant limiting rods penetrate the surface of the right-angle rods. One end of each limiting rod is fixedly connected to a vertical rod, and a second spring is sleeved on the surface of the limiting rod between the vertical rod and the right-angle rod.

[0014] In practical applications, the limit rod restricts the sliding direction of the vertical rod, and the No. 2 spring can automatically push the vertical rod to reset, ensuring stable engagement of the helical teeth. No manual reset is required, ensuring continuous operation of the device.

[0015] Preferably, a side frame is fixedly connected to the outer surface of the lifting frame, the side frame is located on one side of the vertical rod, and the surfaces of the vertical rod and the side frame are provided with opposite helical teeth.

[0016] In practical applications, the helical gear meshing can securely lock the height of the lifting frame, preventing the brush bristles from shaking when the lifting frame falls during cleaning, thus improving cleaning accuracy and operational safety.

[0017] Preferably, a connecting rod is fixedly connected to the surface of the vertical rod facing the right-angle rod, the connecting rod passes through the right-angle rod and is slidably connected to the right-angle rod, and a push plate is fixedly connected to the other end of the connecting rod, the push plate being located on the right side of the cam.

[0018] In practical applications, the cam pushes the push plate, and the connecting rod drives the vertical rod to move away from the helical teeth, releasing the limit action smoothly without manual operation, making it suitable for automated packaging production lines.

[0019] Preferably, a stop bar is fixedly connected between the first support frame above the fixed rod, and the lower end of the movable rod contacts the crossbar.

[0020] In practical applications, the stop bar can prevent the movable rod from rotating excessively during reset, ensuring stable operation of the device.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. This utility model uses several movable rods that can rotate around a fixed rod between the first support frame. When the items to be packaged are conveyed through, they naturally push the movable rods to rotate. The lower end of the movable rod drives the crossbar to slide and rise along the arc-shaped frame. The mounting frame and the lifting frame are synchronously linked, which in turn drives the transmission rod and the surface brush to rise synchronously with the crossbar, achieving automatic adjustment of the brush height. The entire adjustment process requires no manual operation or electrical control system, and is completed solely through the mechanical structure. This not only reduces the cost of manual intervention but also avoids feeding interruptions, ensuring feeding continuity, while simplifying the structural design and reducing the difficulty of later maintenance.

[0023] 2. This utility model features an extension plate, a rotating rod, and a sensing plate on the side wall of the mounting frame. When an item is conveyed to the sensing plate, it pushes the sensing plate to rotate the rotating rod. The cams at both ends of the rotating rod rotate together and push the push plate. The push plate pulls the vertical rod towards the right-angle rod via the connecting rod, causing the vertical rod to disengage from the helical teeth on the side frame surface, thus releasing the limit on the lifting frame. At this time, the lifting frame and the horizontal rod reset under the force of the first spring and their own gravity, and the movable rod also returns to its initial state, preparing for the sensing and brush adjustment of items of different heights. This ensures that the device can be cyclically adapted to continuously conveyed items, improving the overall continuity of feeding and cleaning. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0029] Example 1: An automatic feeding device for a packaging machine, see [link to example]. Figures 1 to 3 The system includes a base 1, on the surface of which are a first support frame 2 and a second support frame 3. A fixed rod 17 is fixedly connected between the inner side walls of the first support frame 2. Several movable rods 18 are equidistantly rotatably connected to the surface of the fixed rod 17. A stop bar 181 is fixedly connected between the first support frames 2 above the fixed rod 17. An arc-shaped frame 19 is fixedly connected to the side wall of the first support frame 2. A crossbar 20 is slidably connected to the inner side of the arc-shaped frame 19. The two ends of the crossbar 20 are located inside the lifting frame 5 on the front and rear sides, respectively. The lifting frame 5 is fixedly connected to the mounting frame 12. The lower end of the movable rod 18 contacts the crossbar 20.

[0030] In the above technical solution, when the item to be packaged passes under the movable rod 18 along the conveying direction, the top of the item will push the movable rod 18 to rotate upward around the fixed rod 17. Simultaneously, the lower end of the movable rod 18 pushes the crossbar 20 to slide and lift along the arc trajectory of the arc frame 19. The crossbar 20 drives the lifting frames 5 at both ends to rise synchronously, and then pulls the mounting frame 12 to rise together through the lifting frames 5. The stop bar 181 can limit the rotation angle of the movable rod 18 to prevent it from swinging continuously when resetting. The linkage between the movable rod 18, the crossbar 20 and the lifting frame 5 is achieved by the item itself pushing, which can drive the height adjustment of the mounting frame 12 without additional power, adapting to the cleaning needs of items of different heights. This not only reduces the cost of manual intervention, but also avoids interruption of feeding, ensures the continuity of feeding, simplifies the structural design and reduces the difficulty of later maintenance.

[0031] Specifically, two extension plates 15 are fixedly connected to the right side wall of the mounting frame 12. The two extension plates 15 are penetrated by a rotating rod 16 and rotatably connected to the rotating rod 16. Cams 162 are fixedly connected to both ends of the rotating rod 16, and a sensor plate 161 is fixedly connected to the surface of the rotating rod 16 between the two extension plates 15. When the item has finished surface cleaning and continues to be conveyed to the sensor plate 161, the side wall of the item will push the sensor plate 161 to rotate around the rotating rod 16. The rotating rod 16 drives the cams 162 at both ends to rotate synchronously. During the rotation of the cams 162, their protrusions will gradually push the push plate 11 on the right side, providing power for the subsequent release of the lifting frame 5 limit. The extension plates 15 provide stable support for the rotating rod 16, ensuring that it rotates without deviation.

[0032] Furthermore, right-angle rods 6 are fixedly connected to the front and rear surfaces of the base 1. Several equidistant limiting rods 7 penetrate the surface of the right-angle rods 6. One end of the limiting rod 7 is fixedly connected to the vertical rod 8. A second spring 701 is sleeved on the surface of the limiting rod 7 between the vertical rod 8 and the right-angle rod 6. A side frame 501 is fixedly connected to the outer surface of the lifting frame 5. The side frame 501 is located on one side of the vertical rod 8. The surfaces of the vertical rod 8 and the side frame 501 are provided with opposite helical teeth 9. A connecting rod 10 is fixedly connected to the surface of the vertical rod 8 facing the right-angle rod 6. The connecting rod 10 penetrates the right-angle rod 6 and is slidably connected to the right-angle rod 6. The other end of the connecting rod 10 is fixedly connected to a push plate 11, which is located on the right side of the cam 162.

[0033] In the above technical solution, when the lifting frame 5 rises, the side frame 501 rises synchronously. The helical teeth 9 on the surface of the side frame 501 can pass normally, and the helical teeth 9 on the vertical rod 8 can restrict the descent of the lifting frame 5, achieving height locking. When the cam 162 pushes the push plate 11, the push plate 11 pulls the vertical rod 8 towards the right-angle rod 6 through the connecting rod 10, causing the two sets of helical teeth 9 to disengage and release the limit on the lifting frame 5. The helical tooth 9 engagement structure can stably lock the height of the lifting frame 5, ensuring that the brush 141 can stay at the current height to clean the items when they pass by. It will only descend and reset after the items pass through the sensing plate 161, preparing for the sensing of items of different heights and the adjustment of the brush 141. This ensures that the device can be cyclically adapted to continuously conveyed items, improving the overall continuity of feeding and cleaning.

[0034] It is worth noting that, such as Figure 1 As shown, rectangular grooves 4 are provided on the front and rear side walls of support frame 2 and support frame 3. A sliding rod 401 is fixedly connected to the inner side of the rectangular groove 4. The two ends of the lifting frame 5 are respectively penetrated by the sliding rods 401 on the inner sides of support frame 2 and support frame 3, and the lifting frame 5 is slidably connected to the sliding rods 401. A spring 402 is sleeved on the surface of the sliding rod 401 below the lifting frame 5. The main function of the spring 402 is to assist in lifting and reduce the impact of the weight of the mounting frame 12 and the lifting frame 5. When the lifting frame 5 slides up and down along the sliding rod 401, the sliding rod 401 restricts the direction of movement of the lifting frame 5, ensuring the stability of the lifting trajectory of the lifting frame 5 and preventing uneven cleaning of the brush bristles 141 due to tilting of the mounting frame 12.

[0035] It is worth noting that, such as Figure 2 and Figure 3 As shown, the mounting frame 12 is located inside the second support frame 3. The front and rear ends of the mounting frame 12 are fixedly connected to the lifting frames 5 on the front and rear sides, respectively. A transmission rod 14 is rotatably connected to the inner side of the mounting frame 12. The surface of the transmission rod 14 is provided with brush bristles 141. A servo motor 13 is fixedly connected to the outer wall of the mounting frame 12. The tail end of the transmission shaft of the servo motor 13 is connected to one end of the transmission rod 14. When the servo motor 13 is started, its transmission shaft drives the transmission rod 14 to rotate at high speed inside the mounting frame 12. The brush bristles 141 on the surface of the transmission rod 14 rotate along with it, sweeping and cleaning the surface of objects passing below. It is worth noting that, to ensure cleaning effectiveness, a dust collection component, such as the nozzle of a vacuum cleaner, can also be installed on the side of the mounting frame 12 to suck up the swept dust and prevent it from flying around.

[0036] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
