Detailed Implementation

[0024] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0025] Depend on Figure 1 Combination Figures 2-5 As shown, a filling machine includes a frame 1, and further includes:

[0026] A filling pump 2 is mounted on a frame 1; there are multiple filling pumps 2; each filling pump 2 is provided with a first connector 21 and a second connector 22, and the filling pump 2 delivers the liquid drawn in the first connector 21 to the second connector 22 and discharges it.

[0027] Power source 3 is used to drive multiple filling pumps 2 to operate, thereby enabling the filling pumps 2 to draw in and discharge liquid;

[0028] The power source 3 is connected to the transmission mechanism 4 and drives the transmission mechanism 4 to operate. The transmission mechanism 4 drives multiple filling pumps 2 to achieve liquid suction and discharge. The advantages of this invention are that the transmission mechanism allows the power source to simultaneously drive multiple filling pumps, resulting in a simple structure, convenient and reliable transmission, reduced parts, good product synchronization performance, easy control, and the ability to process multiple products at once. This invention also has the advantages of simple structure, convenient assembly, reliable operation, and long service life.

[0029] The mechanism includes a drive shaft 41, and the power source 3 is connected to the drive shaft 41 and used to drive the drive shaft 41 to rotate. Each drive shaft 41 is equipped with multiple filling pumps 2. In this way, multiple filling pumps can be set on the drive shaft to complete the filling operation of multiple products at one time, thereby improving filling efficiency and increasing machine operating speed.

[0030] This utility model also includes a sensor 44 and a positioning sleeve 45. The positioning sleeve 45 is mounted on and linked to the transmission shaft 41. The sensor 44 cooperates with the positioning sleeve 45 and is used to monitor the rotational position of the positioning sleeve 45. The transmission shaft 41 is connected to the filling pump 2 through a bevel gear set 42 and is used to drive the filling pump 2 to achieve liquid suction and discharge. The sensor and positioning sleeve cooperate to precisely control the rotational position of the power source, thereby controlling the filling volume with high precision. Specifically, the sensor is connected to the power source through a control circuit board and controls the operation of the power source. The power source can be a servo motor, or it can be a cylinder or a hydraulic cylinder. The bevel gear set facilitates reliable driving of the filling pump to achieve oil suction and discharge. The structure is simple, the transmission is reliable, the transmitted torque is large, and it is easy for the power source to drive.

[0031] The aforementioned drive shaft 41 has at least two shafts, each equipped with multiple filling pumps 2. Different drive shafts 41 are linked by meshing helical gear sets 43. The filling pumps 2 on different drive shafts 41 are located on both sides of the frame 1. This allows for multiple drive shafts, each equipped with multiple filling pumps. Specifically, this invention uses two drive shafts and positions the filling pumps on both sides of the frame, which optimizes space utilization and saves space. A single power source reduces the size of the filling machine, lowers production costs, and reduces energy consumption during operation. This structure also ensures good synchronization between different filling pumps, is simple in design, and provides convenient and reliable liquid drainage.

[0032] This invention also includes an adjustment mechanism 5, which is mounted on the frame 1 and connected to the filling pump 2. The filling volume is adjusted by changing the angle of the filling pump 2. The filling pump 2 includes a cylinder 23 and a rotating shaft 24. The first connector 21 and the second connector 22 are both connected to the inner cavity of the cylinder 23. The rotating shaft 24 is inserted into the cylinder 23 and is driven to rotate by the transmission mechanism 4 to achieve liquid suction and discharge. The adjustment mechanism allows for individual adjustment of the discharge volume of each pump, resulting in high product discharge accuracy. It also allows for fine-tuning of individual filling pumps, facilitating maintenance and debugging. The adjustment mechanism ensures that the various filling pumps do not interfere with each other. This invention allows material to be fed from the first connector and discharged from the second connector; alternatively, material can also be fed from the second connector and discharged from the first connector.

The adjusting mechanism 5 adjusts the insertion depth of the rotating shaft 24 into the cylinder 23 by adjusting the tilt angle of the pump body 25, thereby adjusting the filling volume. Specifically, the rotating shaft achieves liquid suction and discharge through rotation. The adjusting mechanism adjusts the insertion depth of the rotating shaft into the cylinder by adjusting the tilt angle of the pump body. At this time, the filling volume of the filling pump is adjusted due to the notch groove on the rotating shaft.

[0034] The adjustment mechanism 5 includes a fixed base 51, an adjustment base 52, and an adjustment component 53. The filling pump 2 is mounted on the fixed base 51 and rotatably engages with it.

The fixed base 51 is provided with a limiting hole 511 for limiting the rotation of the adjustment base 52. This structure makes product adjustment convenient and simple. Typically, one end of the adjustment component is fixed to the frame, and the other end is connected to the adjustment base. By rotating the adjustment base, the position of the pump body is adjusted, thereby adjusting the insertion amount of the rotating shaft and thus adjusting the filling volume.

[0035] The cylinder body 23 is integrally formed from ceramic material, and the pump body 25 is integrally formed from metal material. The rotating shaft 24 has a notch 241 at one end inserted into the cylinder body 23. The ceramic cylinder body ensures high product precision, easy processing, and convenient production. It is also wear-resistant, has a long service life, and provides sufficient surface lubrication during liquid suction and discharge, preventing collision wear.
