Technical Field
[0001] This utility model relates to the field of packaging equipment technology, specifically to a packaging bag hopper. Background Technology
[0002] Packaging bag silos are storage equipment used to store packaging bags. They typically consist of a frame structure, a material carrying platform, a conveying device, and a control system. They have the functions of automatic feeding, orderly storage, and quantitative supply. They can achieve layered storage and precise output of packaging bags through mechanical transmission or pneumatic devices. They are suitable for packaging production lines in industries such as food and pharmaceuticals, and can effectively prevent packaging bags from folding or breaking, ensuring the continuity and stability of subsequent packaging processes.
[0003] For example, the Chinese authorized patent CN215707509U, entitled "A silo-type packaging bag feeding device", includes a bag feeding mechanism, a bag picking mechanism, and a bag delivery mechanism. The bag feeding mechanism is provided with a first positioning unit for storing packaging bags. The bag picking mechanism includes a moving component, a bag picking component, and a second positioning unit for fixing the packaging bags. The bag picking component moves the packaging bags vertically from the bottom of the first positioning unit to the second positioning unit. The moving component drives the bag picking mechanism to move horizontally to separate the packaging bags from the bag feeding mechanism and move the packaging bags to the bottom of the bag delivery mechanism. The bag delivery mechanism transfers the packaging bags from the second positioning unit, waiting for subsequent stations to pick them up.
[0004] While the existing technologies mentioned above can store packaging bags, they cannot achieve a continuous supply of large quantities of packaging bags on the packaging production line. Not only is the supply stability poor, but it also affects the packaging efficiency of the entire production line. Therefore, they do not meet the current needs. In response, we propose a packaging bag silo. Utility Model Content
[0005] The purpose of this utility model is to provide a packaging bag hopper to solve the problem mentioned in the background art that the packaging bag hopper not only has poor material supply stability, but also affects the packaging efficiency of the entire production line.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a packaging bag hopper, comprising two side plates, with two front-to-back distributed top plates at the upper end between the side plates, the top plates being fixed to the side plates by bolts, and the side plates and top plates forming the hopper body. The hopper body contains multiple parallel-distributed trays, with multiple limiting blocks installed on the edge of the upper surface of each tray. Movable seats are fixed to both sides of the bottom of each tray by screws. Multiple guide rails corresponding to the movable seats are provided on the inner sidewalls of the side plates, and the guide rails are fixed to the side plates by screws. Guide grooves are provided inside the guide rails, and multiple equidistantly distributed movable wheels are provided inside the guide grooves. The shafts at one end of each movable wheel are connected to the movable seats via bearings. A movable wheel drive mechanism is provided inside the movable seats.
[0007] Preferably, the rear end of the inner sidewall of the side plate is provided with multiple mounting brackets, and the mounting brackets are fixed to the side plate by screws. A material sensor is installed at the upper end of the mounting bracket, and the detection end of the material sensor extends to the upper surface of the material tray through the hollow groove of the material tray.
[0008] Preferably, the moving wheel drive mechanism includes a transmission cavity, inside which are provided two transmission shafts, which are respectively connected to the moving wheels in the middle section and the rear section. The front and rear transmission shafts are connected by belt drive. One end of the rear transmission shaft is fixedly provided with a driven helical gear. A servo motor is installed above the transmission cavity. The output shaft of the servo motor is equipped with a driving helical gear, and the driving helical gear is meshed with the driven helical gear.
[0009] Preferably, the front end of the inner sidewall of the side plate is provided with multiple fixed seats, and a first auxiliary guide wheel is mounted on the upper part of the fixed seat through a bearing, and the first auxiliary guide wheel is in contact with the inner sidewall of the movable seat.
[0010] Preferably, multiple connecting frames are fixedly provided on both sides of the front end of the side plate, and a second auxiliary guide wheel is installed at the front end of the connecting frame through a rotating shaft. The material tray is in an extended state, and the bottom of the movable seat is in contact with the second auxiliary guide wheel.
[0011] Preferably, a front baffle is installed at the front end of the tray by screws, and a handle is installed on the outer wall of the front baffle.
[0012] Preferably, a mounting base is fixedly installed at the bottom of the side plate, and the mounting base has multiple mounting holes inside, which are fixed to the workbench of the production line by screws.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model achieves continuous supply of packaging bags by using multiple trays. A material sensor is installed at the bottom of each tray. During operation, the trays are stacked in layers, with the upper tray prioritizing the supply of packaging bags. The material sensor at the bottom continuously monitors the supply. Once the upper tray is depleted of packaging bags, a signal is transmitted to the control system. The system immediately drives the tray to retract and reset, while simultaneously controlling the lower tray to automatically extend to the bag supply station, seamlessly connecting the supply process and ensuring a continuous supply of packaging bags to the production line. On one hand, the multi-layer tray continuous supply mode greatly reduces frequent manual replenishment operations, lowering labor costs and intensity, and improving production efficiency. On the other hand, the material sensor and automatic switching mechanism prevent production line stoppages due to bag supply interruptions, ensuring the continuity of the packaging process.
[0015] 2. This utility model features a material tray drive structure. The guide rail has a guide groove inside, and multiple moving wheels are installed inside the guide groove. The shafts of the moving wheels are connected to movable seats on both sides of the bottom of the material tray. At the same time, the movable seats have a transmission cavity inside, and two transmission shafts are installed at the front and rear of the transmission cavity, respectively connected to the rear moving wheel and the middle moving wheel. By turning on the servo motor, its output shaft drives the active helical gear to rotate. Under the meshing of the helical gear on the transmission shaft, the rear moving wheel is driven to rotate. At the same time, the front and rear transmissions are connected by a belt to realize the synchronous rotation of the middle moving wheel and the rear moving wheel, thereby allowing the material tray to extend and retract freely. With the help of the material sensor, continuous supply of packaging bags can be achieved.
[0016] 3. This utility model features a first auxiliary guide wheel mounted on the inner side of the side plate via a fixed seat. The first auxiliary guide wheel fits against the inner wall of the movable seat. Simultaneously, second auxiliary guide wheels are mounted on both sides of the front end of the side plate via connecting frames. The second auxiliary guide wheels support the ground of the movable seat of the extended material plate, thus creating a dual guiding and support system for the movement of the material tray. This effectively prevents the material tray from tilting or shifting during the extension and retraction process, making the material tray's running trajectory more precise. Moreover, the stable guiding and support structure ensures the smoothness of material tray switching, avoiding problems such as packaging bags falling or misaligned stacking caused by material tray shaking, and ensuring the continuity and accuracy of packaging bag supply.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Please see Figure 1-4 An embodiment of this utility model provides a packaging bag hopper, including two side plates 1. Two top plates 2 are provided at the upper end between the side plates 1, and the top plates 2 are fixed to the side plates 1 by bolts. The side plates 1 and the top plates 2 constitute the hopper body. The hopper body has multiple parallel material trays 3 inside. Multiple limiting blocks 4 are installed on the edge of the upper surface of the material trays 3. Movable seats 10 are fixed to both sides of the bottom of the material trays 3 by screws. Multiple guide rails 9 corresponding to the movable seats 10 are provided on the inner side wall of the side plates 1. The guide rails 9 are fixed to the side plates 1 by screws. The guide rails 9 have guide grooves 11 inside. Multiple equidistant moving wheels 12 are provided inside the guide grooves 11. The shaft at one end of the moving wheel 12 is connected to the movable seat 10 by bearings. The movable seat 10 has a moving wheel drive mechanism inside.
[0024] The movable seat 10 engages with the guide groove 11 of the guide rail 9, allowing the movable wheel 12 to roll within the guide groove 11. The movable wheel drive mechanism drives the movable wheel 12 to rotate, thereby causing the material tray 3 to move telescopically along the guide rail 9 between the side plates 1. The limiting block 4 can limit the packaging bags placed on the material tray 3 to prevent them from slipping. The design of the guide rail 9 and the movable wheel 12 makes the movement of the material tray 3 smoother and more stable, reducing frictional wear and extending the service life of the equipment. The limiting block 4 ensures that the packaging bags are fixed in position on the material tray, preventing displacement or falling during the movement of the material tray, ensuring the accuracy and stability of subsequent bag feeding, and improving production efficiency.
[0025] Please see Figure 2 Multiple mounting brackets 7 are provided at the rear end of the inner side wall of the side plate 1, and the mounting brackets 7 are fixed to the side plate 1 by screws. A material sensor 8 is installed at the upper end of the mounting bracket 7, and the detection end of the material sensor 8 extends to the upper surface of the material tray 3 through the hollow groove of the material tray 3.
[0026] The material sensor 8 detects in real time whether there are packaging bags on the corresponding material tray 3 through the hollowed-out slots of the material tray 3. When it detects that the packaging bags on the upper material tray 3 are used up, the sensor transmits a signal to the control system, triggering a corresponding action. Benefits: Real-time monitoring of the number of packaging bags on the material tray, automatically determining whether to switch material trays, eliminating the need for constant manual monitoring and reducing labor costs; ensuring the continuity of packaging bag supply, avoiding production line shutdowns due to bag supply interruptions, and improving production efficiency and automation.
[0027] Please see Figure 3 The moving wheel drive mechanism includes a transmission cavity 15, inside which are provided two transmission shafts 16, and the transmission shafts 16 are respectively connected to the moving wheels 12 in the middle section and the rear section. The front and rear transmission shafts 16 are connected by a belt 19. One end of the rear transmission shaft 16 is fixedly provided with a driven helical gear 18. A servo motor is installed above the transmission cavity 15. The output shaft of the servo motor is equipped with a driving helical gear 17, and the driving helical gear 17 is meshed with the driven helical gear 18.
[0028] When the servo motor is turned on, its output shaft drives the active helical gear 17 to rotate. The active helical gear 17 meshes with the driven helical gear 18, driving the rear transmission shaft 16 to rotate, which in turn drives the rear moving wheel 12 to rotate. Simultaneously, the front and rear transmission shafts 16 are connected by a belt 19, achieving synchronous rotation of the intermediate moving wheel 12 and the rear moving wheel 12, thereby driving the material tray 3 to move. The combination of the servo motor and gear and belt drives enables precise and stable power transmission, ensuring that the material tray 3 moves quickly and accurately. The moving speed and position of the material tray 3 can be flexibly controlled according to production needs, improving the material tray switching efficiency, reducing problems such as material tray jamming and misalignment caused by unstable drive, and ensuring the stable operation of the production line.
[0029] Please see Figure 3 The front end of the inner wall of the side plate 1 is provided with multiple fixed seats 13. A first auxiliary guide wheel 14 is installed above the fixed seat 13 through a bearing. The first auxiliary guide wheel 14 is in contact with the inner wall of the movable seat 10. The first auxiliary guide wheel 14 is in contact with the inner wall of the movable seat 10. During the movement of the material tray 3, it plays an auxiliary guiding role for the movable seat 10, restricts the lateral displacement of the movable seat 10, and makes the material tray 3 move smoothly along the predetermined direction.
[0030] Please see Figure 4Multiple connecting brackets 20 are fixedly installed on both sides of the front end of the side plate 1. The front end of the connecting bracket 20 is equipped with a second auxiliary guide wheel 21 via a rotating shaft. When the material tray 3 is in the extended state, the bottom of the movable seat 10 is in contact with the second auxiliary guide wheel 21. When the material tray 3 extends, the bottom of the movable seat 10 is in contact with the second auxiliary guide wheel 21, which supports the movable seat 10, shares the weight of the material tray 3, and guides the material tray 3 during its movement. This effectively reduces the pressure on the material tray 3 during movement, reduces the load on the moving wheel 12 and the guide rail 9, and reduces wear; it further improves the stability and reliability of the material tray 3's movement, and prevents problems such as sinking or tilting of the material tray during its extension.
[0031] Please see Figure 1 A front baffle 5 is installed at the front end of the material tray 3 by screws. A handle 6 is installed on the outer wall of the front baffle 5. The front baffle 5 is installed at the front end of the material tray 3 to prevent the packaging bag from sliding forward. The handle 6 is convenient for manual operation. When manual intervention or adjustment of the material tray is required, the material tray can be pushed or pulled by the handle.
[0032] Please see Figure 1 A mounting base 22 is fixedly installed at the bottom of the side plate 1. The mounting base 22 has multiple mounting holes inside, and is fixed to the workbench of the production line by screws. By passing screws through the mounting holes of the mounting base 22, the side plate 1 of the hopper is fixed to the workbench of the production line, realizing a stable connection between the hopper and the production line. This ensures that the hopper remains stable during production and will not shift due to vibrations or other factors caused by equipment operation, thus guaranteeing the coordinated operation of the hopper and the production line.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
