[0019] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In the present utility model, it needs to be explained that if there are directional indications involved in the embodiments of the present utility model (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0021] A filling machine tank positioning mechanism, such as Figure 1 - Figure 4 As shown, it includes a bracket 1 arranged on both sides of the can conveying channel, a first driving device 2 is fixedly installed on the bracket, a connecting plate 3 is installed on the telescopic shaft of the first driving device, a second driving device 4 is installed on the connecting plate, the telescopic end of the second driving device is connected to a push plate 5, and a positioning block 7 for positioning the can 6 is installed on the push plate.

[0022] The can channel is provided with three channels. After the empty can is transported to the can channel, the telescopic end of the second driving device pushes the push plate, so that the positioning blocks on both sides of the can transport channel move a small distance to support the can body, so as to position the empty can. When different can types need to be replaced, the first driving device pushes and pulls the connecting plate, thereby driving the telescopic end of the second driving device to push and pull the push plate, so that the positioning blocks on both sides of the can transport channel move to adapt to the spacing of different can bodies, so that the positioning of different can types can be easily adjusted, and the adjustment is more convenient; in addition, since only the first driving device is installed and fixed on the bracket, the second driving device is not fixed on the bracket, and it is only fixedly connected to the telescopic shaft of the first driving device through the connecting plate, forming a two-level linkage effect, and its operation is also more convenient.

[0023] In another embodiment, the first driving device adopts a three-cylinder air cylinder, and the second driving device adopts a thin air cylinder. The manual valve 13 is used to control the start of the thin air cylinder, and its operation is more convenient.

[0024] In another embodiment, a linear guide 8 is installed on the bracket, the slider of the linear guide is fixed on the bracket, and the guide end of the linear guide is connected to the push plate. The linear guide is connected to the push plate, so that the telescopic end of the second drive device pushes and pulls the push plate, thereby driving the linear guide to push and pull the push plate, so that the force is more uniform and the movement effect is better; in addition, two linear guides are arranged on the bracket, and the two linear guides are respectively arranged on both sides of the first drive device and the second drive device. Through the design of the two linear guides, the force is further more uniform and the movement effect is better; in addition, by replacing the original linear bearing structure with a linear guide, the problem that the linear bearing structure is easy to get stuck due to excessive clearance, thereby causing frequent abnormal positioning alarms and shutdowns, requiring manual shutdown processing, increasing the machine failure rate and seriously affecting the processing and maintenance costs can be solved.

[0025] In another embodiment, a side guard bar 9 for blocking the side of the can is provided on the bracket. The side guard bar 9 can better protect the can body and play a better fixing and supporting role.

[0026] In another embodiment, the side guard rod comprises an upper side guard rod and a lower side guard rod, and a gap is reserved between the upper side guard rod and the lower side guard rod, and the positioning block extends from the gap between the upper side guard rod and the lower side guard rod to position the can. The upper side guard rod and the lower side guard rod can further be well fixed and supported on the upper and lower parts of the can body; in addition, by reserving a gap between the upper side guard rod and the lower side guard rod, the positioning block can be better extended from the gap between the upper side guard rod and the lower side guard rod to position the can.

[0027] In another embodiment, connecting blocks are provided on the upper and lower side guard rods, and the upper and lower ends of the connecting blocks are respectively fixed to the upper and lower side guard rods, and the connecting rods 11 pass through the through holes 12 on the push plate and are fixed to the bracket.

[0028] The above embodiments are only used to illustrate the detailed scheme of the utility model. The utility model is not limited to the above detailed scheme, that is, it does not mean that the utility model must rely on the above detailed scheme to be implemented. Those skilled in the art should understand that any improvement to the utility model, equivalent replacement of various raw materials of the utility model product, addition of auxiliary components, selection of specific methods, etc., all fall within the protection scope and disclosure scope of the utility model.
