Description

Technical Field

[0001] This utility model relates to the field of packaging machines, and in particular to a feeding mechanism for a vertical packaging machine. Background Technology

[0002] Vertical packaging machines are automatic packaging equipment widely used in the food, pharmaceutical, and cosmetic industries. They are primarily used to package products according to specific specifications and methods. When in use, vertical packaging machines require a feeding mechanism to transport materials to the packaging machine, which then packages the materials. Generally, a conveyor belt is used for material transport.

[0003] A search of Chinese patents revealed publication number CN220448264U, entitled "Feeding Mechanism for an Automatic Packaging Machine," which relates to the field of packaging machine technology. The feeding mechanism includes a main body of the automatic packaging machine, a roller conveyor mounted on the main body, and a guide plate at one end of the roller conveyor. The free end of the guide plate is positioned above the conveyor belt to guide the items to be packaged from the roller conveyor onto the conveyor belt. The conveyor belt is mounted on a mounting base, and a pressing device is provided on the mounting base. The pressing device is used to press the items to be packaged on the conveyor belt. The pressing device includes a bracket mounted on the mounting base, with a telescopic rod on the top of the bracket. The bottom end of the telescopic rod is connected to a rotating seat and is used to push the rotating seat to move vertically, allowing the packaged items to preferentially contact the elastic band, reducing impact damage. This also allows the direction of the pressing plate to be adjusted according to the spacing of the limiting plates, preventing the limiting plates from affecting the pressing operation.

[0004] Existing feeding mechanisms are inconvenient for tension adjustment. During use, the conveyor belt is prone to loosening and requires tensioning. Adjustment involves loosening the bolts at both ends of the drive roller, moving the drive roller to the desired position, and then tightening the bolts. This adjustment process is cumbersome, increases workload, reduces efficiency, and results in poor accuracy. It can also cause the ends of the drive tube to tilt, affecting the performance of the conveyor belt. Furthermore, it lacks a cleaning function, causing powdery materials to adhere to the surface of the conveyor belt, contaminating it and affecting hygiene. To address these problems, we propose a feeding mechanism for a vertical packaging machine. Utility Model Content

[0005] The purpose of this invention is to provide a feeding mechanism for a vertical packaging machine, which has the advantages of easy tension adjustment and cleaning function.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a feeding mechanism for a vertical packaging machine, including a housing, a support leg bolted to the bottom of the housing, a conveying mechanism disposed inside the housing, a fixing plate bolted to both the front and back of the housing, a fixing rod bolted to the surface of the fixing plate, a telescopic rod slidably sleeved on the inner wall of the fixing rod, a fixing ring bolted to the outer end of the telescopic rod, a screw threadedly connected to the inner wall of the telescopic rod, and the surface of the screw rotatably sleeved with the inner wall of the fixing plate, a fixing shell bolted to the surface of the fixing plate, a first bevel gear fixedly sleeved on one end of the screw, a second bevel gear meshing on the surface of the first bevel gear, a drive shaft fixedly sleeved between the axes of the two second bevel gears, and the drive shaft rotatably sleeved with the inner walls of the housing and the fixing shell.

[0007] By adopting the above technical solution, the rotation of the turntable causes the transmission shaft to rotate, which in turn causes the second bevel gear to rotate. The rotation of the second bevel gear causes the first bevel gear to rotate, which in turn causes the screw to move the telescopic rod. The movement of the telescopic rod then causes the fixed ring to move the movable transmission roller. This method facilitates the adjustment of tension, reduces workload, improves adjustment efficiency, and ensures adjustment accuracy.

[0008] The present invention is further configured as follows: a fixed seat is bolted between the inner walls of the housing; a telescopic plate is slidably sleeved on the inner wall of the fixed seat; a scraper is bolted to the top of the telescopic plate; a pressure plate is slidably connected to the inner wall of the fixed seat; an adjusting bolt is rotatably connected to the bottom of the pressure plate and threadedly connected to the inner wall of the fixed seat; a tension spring is fixedly connected between the pressure plate and the telescopic plate by a fastener; a first motor is bolted to the surface of the housing; the output end of the first motor extends into the interior of the housing and is connected to a brush roller via a coupling; and the other end of the brush roller is rotatably connected to the inner wall of the housing.

[0009] By adopting the above technical solution, the conveyor belt is cleaned by a scraper, and the pressure plate is moved by rotating the adjusting bolt, which changes the elasticity of the tension spring, thereby adjusting the pressure of the scraper on the conveyor belt. The first motor drives the brush roller to rotate and clean the conveyor belt, thus achieving the purpose of cleaning, reducing maintenance and ensuring the cleanliness of the conveyor belt.

[0010] The present invention is further configured such that: the conveying mechanism includes a fixed transmission roller and a movable transmission roller, both ends of the fixed transmission roller are rotatably sleeved with the inner wall of the housing, the surface of the movable transmission roller is rotatably sleeved with the inner wall of the fixed ring, the front and back of the housing are provided with sliding grooves, the inner walls of the sliding grooves are slidably connected with sliders, and the inner walls of the two sliders are respectively rotatably sleeved with both ends of the movable transmission roller, one end of the fixed transmission roller is bolted with a second motor, and the second motor is bolted with the surface of the housing, and the surfaces of the fixed transmission roller and the movable transmission roller are connected by a conveyor belt.

[0011] By adopting the above technical solution, a conveying mechanism is set up. The second motor rotates to drive the fixed transmission roller, and the rotation of the fixed transmission roller drives the conveyor belt to rotate, which facilitates material conveying and feeding.

[0012] The present invention is further configured such that: a fixing block is bolted to the surface of the fixing shell on the front side, and the fixing block is rotatably sleeved with the surface of the transmission shaft; and a fixing bolt is threaded to the inner wall of the fixing shell.

Scraper 15 is in close contact with conveyor belt 26 to clean conveyor belt 26. In conjunction with the first motor 19 driving brush roller 20 to rotate and clean conveyor belt 26, scraper 15 and brush roller 20 clean conveyor belt 26 at the same time. The waste residue after cleaning falls into collection box 31 for collection, thereby achieving the purpose of cleaning function. By loosening the fixing nut 30 and rotating the adjusting bolt 17, the adjusting bolt 17 moves the pressure plate 16. The movement of the pressure plate 16 changes the elasticity of tension spring 18. When the elasticity of tension spring 18 changes, the pressure of scraper 15 on conveyor belt 26 changes, thereby achieving the purpose of adjusting the pressure of scraper 15.
