Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a material tray bagging multiplication mechanism. Background Technology

[0002] In the field of packaging machine technology, tray bagging is a key link in the material packaging process, and its efficiency directly affects the overall production line capacity. At present, traditional tray conveying mechanisms mostly adopt a single-stage drive and single-stage displacement design, that is, the tray frame is directly driven to move through the drive component, and the displacement distance of the tray frame is consistent with the output displacement of the drive component, which cannot achieve displacement multiplication.

[0003] On the one hand, if the material tray conveying range needs to be expanded to adapt to the bagging requirements of different specifications, the stroke of the drive components (such as motors and lead screws) needs to be increased, resulting in an increase in the overall size of the mechanism and an increase in the installation space requirements, making it difficult to adapt to the compact production line layout. On the other hand, under the same drive stroke, the material tray conveying efficiency of the traditional mechanism is low, which cannot meet the needs of "short time and long distance" feeding in high-speed packaging scenarios, and is likely to cause production line bottlenecks. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a material tray bagging multiplication mechanism.

[0005] This utility model proposes a material tray bagging multiplication mechanism, including a base, a feeding drive module mounted on the top of the base, and a movable plate slidably connected to the upper part of the base. The feeding drive module drives the movable plate to move. Both ends of the movable plate are rotatably connected to linkage synchronous wheels. The linkage synchronous wheels are connected to a linkage synchronous belt. The upper half of the linkage synchronous belt is connected to an upper linkage plate, and the lower half is connected to a lower linkage plate. The upper and lower linkage plates are diagonally distributed. A material tray frame is slidably connected to the upper part of the movable plate. The top of the upper linkage plate is connected to the material tray frame, and the bottom of the lower linkage plate is connected to the base.

[0006] Furthermore, the base and the movable plate, as well as the movable plate and the material tray frame, are slidably connected by linear guide rails.

[0007] Furthermore, the feeding drive module includes a support plate mounted on the top of the base. A motor is mounted on the bottom of the support plate, and a lead screw is rotatably connected to the top. The lead screw is externally threaded to a drive seat, and the drive seat is connected to a movable plate to drive the movable plate to reciprocate. The motor and the lead screw are driven by a synchronous belt drive kit.

[0008] Furthermore, the synchronous belt drive kit includes a driving synchronous pulley mounted on the motor drive end, a driven synchronous pulley mounted on the lead screw end, and a transmission synchronous belt connected to the outside of the driving synchronous pulley and the driven synchronous pulley.

[0009] Furthermore, a pusher cylinder is installed on one side of the top of the tray frame, and a tray is placed on the other side to push the tray out of the tray frame.

[0010] Furthermore, an clearance hole is provided at the top of the base, and a baffle is connected to the bottom of the movable plate. The baffle extends into the interior of the base through the clearance hole, and the clearance hole is set as an elongated hole with a length greater than that formed by the baffle.

[0011] Furthermore, photoelectric sensors are symmetrically installed inside the base. The photoelectric sensors are located at both ends of the clearance hole. The baffle passes through the photoelectric sensors to detect the position of the movable plate.

[0012] The beneficial effects of this utility model are as follows: Through the coordinated design of the base, feeding drive module, movable plate, linkage synchronous wheel, linkage synchronous belt, upper and lower linkage plates and material tray frame, the feeding drive module drives the movable plate to move. With the lower linkage plate fixed to the base limiting the linkage synchronous belt, the linkage synchronous belt drives the upper linkage plate and material tray frame to achieve a displacement twice that of the movable plate. Without increasing the stroke of the drive components, the material tray conveying range is effectively expanded. This avoids the mechanism from being too large to fit the compact production line layout and improves the material tray conveying efficiency to meet the needs of high-speed packaging.

[0015] Reference Figure 1-5This utility model proposes a material tray bagging multiplication mechanism, including a base 1. A feeding drive module 2 for power output is fixedly installed at the top of the base 1. This module consists of a support plate 21, a motor 22, a lead screw 23, a drive seat 24, and a synchronous belt drive assembly. The support plate 21 is vertically fixed to the top of the base 1, and the motor 22 (a servo motor) is bolted to its bottom. The lead screw 23 is rotatably connected to the top via bearings. The drive seat 24 is threadedly connected to the outside of the lead screw 23, and the drive seat 24 is fixedly connected to the bottom of a movable plate 3, enabling synchronous movement of the movable plate 3. This provides the power output for the motor 22 and the lead screw 23. The transmission is achieved through a synchronous belt drive kit, which includes a driving synchronous pulley 25 fixed to the drive end of the motor 22, a driven synchronous pulley 26 fixed to the end of the lead screw 23, and a transmission synchronous belt 27 sleeved on the outside of the driving synchronous pulley 25 and the driven synchronous pulley 26. When the motor 22 starts, the driving synchronous pulley 25 rotates with the motor output shaft, and drives the driven synchronous pulley 26 to rotate synchronously through the transmission synchronous belt 27, thereby driving the lead screw 23 to rotate. The rotational motion of the lead screw 23 is converted into the linear motion of the drive seat 24 through the threaded engagement, and finally drives the movable plate 3 to reciprocate linearly along the base 1, providing initial power for subsequent multiplication transmission. The movable plate 3 and the base 1 are slidably connected by a linear guide rail 6. The linear guide rail 6 eliminates sliding friction interference between the movable plate 3 and the base 1, ensuring that the movable plate 3 moves smoothly along the set direction and avoiding transmission accuracy affected by friction jamming. At both ends of the movable plate 3, a linkage synchronous wheel 31 is rotatably connected by a rotating shaft. A closed linkage synchronous belt 32 is fitted around the outside of the two linkage synchronous wheels 31. The upper half of the linkage synchronous belt 32 is fixedly connected to the bottom end of the upper linkage plate 33, and the lower half is fixedly connected to the top end of the lower linkage plate 34. The upper linkage plate 33 and the lower linkage plate 34 are diagonally distributed. At the same time, the upper linkage plate 3... The top of 3 is fixedly connected to the bottom of the tray frame 4, and the bottom of the lower linkage plate 34 is fixedly connected to the top of the base 1. This structural design is the core of displacement multiplication. When the feeding drive module 2 drives the movable plate 3 to move in a certain direction, since the lower linkage plate 34 is fixed on the base 1, it will form a fixed tension on the lower half of the linkage synchronous belt 32. Under the guidance of the linkage synchronous wheel 31, the linkage synchronous belt 32 will drive the upper linkage plate 33 to move in the same direction, and the moving distance of the upper linkage plate 33 is twice the moving distance of the movable plate 3. Finally, the tray frame 4 will achieve double displacement, effectively improving the efficiency and coverage of tray bagging. The material tray frame 4 and the movable plate 3 are also slidably connected by a linear guide rail 6. The linear guide rail 6 is parallel to the guide rail between the base 1 and the movable plate 3, further ensuring that the moving direction of the material tray frame 4 is consistent with that of the movable plate 3, and avoiding deviation that could cause the material tray to fall or the bagging to be misaligned. On one side of the top of the material tray frame 4, a pusher cylinder 5 is fixedly installed by a cylinder bracket, and the material tray 7 to be conveyed is placed on the other side of the top. When the material tray frame 4 moves to the designated bagging position under the action of multiplier transmission, the piston rod of the pusher cylinder 5 will extend towards the material tray 7, pushing the material tray 7 off the material tray frame 4 so that it can enter the subsequent bagging process. To ensure the positional accuracy of the mechanism and prevent the movable plate 3 or the material tray 4 from moving beyond its travel range, a position detection component is designed into this mechanism. An elongated obstruction hole 11 is provided at the top of the base 1. A baffle 35 is fixed to the bottom of the movable plate 3 by bolts. The baffle 35 extends vertically downward and passes through the obstruction hole 11 into the interior of the base 1. The length of the obstruction hole 11 is greater than the length of the baffle 35, providing sufficient space for the baffle 35 to move with the movable plate 3 and preventing interference between the two. Inside the base 1, two photoelectric sensors 12 are symmetrically installed along the length of the obstruction hole 11, and the two photoelectric sensors 12 are located at opposite ends of the obstruction hole 11. When the movable plate 3 moves the baffle 35, the baffle 35 will pass through the two photoelectric sensors 12. When the baffle 35 blocks one of the photoelectric sensors 12, it indicates that the movable plate 3 has moved to the initial position or the limit position. The photoelectric sensor 12 will send a signal to the control system, and the control system will then control the motor 22 to stop or reverse, thereby realizing the position limit and precise control of the movable plate 3 and ensuring the safety and stability of the mechanism operation.
