Description

Technical Field

[0001] The utility model relates to the technical field of filling machines, and particularly relates to a quick-change trolley for filling. Background Art

[0002] A filling machine is an essential device for filling substances for preservation or sale, such as liquid beverages, cosmetics, food, etc. There are thousands of varieties on the market for liquid beverages, cosmetics, food, etc. As the types of enterprise products increase, the products to be produced in the same period gradually increase. For enterprises, when filling in multiple varieties and small batches, it is necessary to ensure the filling efficiency and save the downtime for filling and cleaning. For each variety of filling, a filling machine is required. Thus, with the diversification of products, general enterprises have hundreds or thousands of varieties to be filled. If a filling machine only fills one variety, many filling machines are needed to ensure the filling efficiency.

[0003] The cost of the filling machine is relatively high, which is extremely high for enterprises, and the one-time investment cost is extremely large. Due to cost and scale limitations, enterprises cannot increase the filling machines indefinitely, resulting in increasing production pressure. They can only clean the existing filling equipment and then replace it with another product. When changing varieties, it is necessary to thoroughly clean the storage bin, three-way valve, piston rod, and filling head of the filling machine. In this way, the entire filling production line has to stop production due to model change, and the disassembly of parts is complex, greatly reducing the production efficiency and bringing huge losses to enterprises.

[0004] To address the above problems, when improving the filling machine, the bins to be filled and the bin panels are usually fixed on the trolley, and the trolley is used to drive the bin to dock with the working table surface to be filled. That is to say, each bin requires a corresponding trolley to achieve quick change of the equipment. However, in actual use, except for the bin panel and bin that are participating in filling, only one quick-change trolley is needed to achieve quick change. If an enterprise has multiple filling bins, when changing varieties, only one trolley needs to dock with the filling bin of the corresponding variety. After docking, the filling bin is replaced to the corresponding working table surface position. The other unused filling bins do not always require the corresponding trolley structure. Therefore, fixing a trolley structure for each filling bin will result in waste of resources. At the same time, when the filling bin is filling, the trolley structure integrated with the filling bin will affect the standing position and operation of on-site operators, which is not conducive to monitoring during the operation process. Content of the Utility Model

The piston cylinder 6 pulls, and the filling material enters the storage cavity of the piston cylinder 6; when the switch of the first opening 701 of the three-way valve 7 is closed, the switch of its third opening 703 is opened, and the piston cylinder 6 pushes the material to achieve filling through the third opening 703. By setting the closing of the switch of the three-way valve 7, quantitative filling can be achieved. Now, after quantitatively taking the filling material and entering the material cylinder, it is then filled into the corresponding container through the third opening 703, and quantitative filling can be achieved.

[0049] In this embodiment, a number of three-way valves 7 are provided on the silo panel 2. A three-way valve positioning plate 8 is provided outside each three-way valve 7, and the silo panel 2 and the three-way valve positioning plate 8 are fixedly connected through a dovetail groove structure 9. The adjacent two three-way valve positioning plates 8 are also fixedly connected by a cross fixing plate 10.

[0050] Embodiment 2:

[0051] The difference between this embodiment and Embodiment 1 is:

[0052] One end of the lower surface of the fluent strip racks 507 of the first support member and the second support member is provided with a guide rod 510, and the other end is provided with a lead screw 509. A lead screw fixing frame 511 is longitudinally arranged on the cart 3. One end of the lead screw fixing frame 511 is vertically threadedly connected to the lead screw 509, and the other end is vertically inserted into the guide rod 510. By adjusting the lead screw 509 and the guide rod 510, when docking with the silo panel 2, the height between the fluent strip rack 507 and the silo panel 2 can be adjusted, so that the pin block 513 corresponds to the through hole of the sleeve 504, facilitating the insertion of the pin column for fixation.

[0053] Other structures are the same as those in Embodiment 1 and will not be elaborated here.

[0054] Embodiment 3:

[0055] The difference between this embodiment and Embodiment 2 lies in:

[0056] The fluent strip racks 507 of the first support member and the second support member are both slot structures, and a number of rollers 515 are sequentially rotatably connected in the slot structures; both sides of the lower surface of the sleeve 504 are step structures. When the cart 3 is docked with the silo panel 2, the step structures on the lower surface of the sleeve 504 contact the rollers 515 in the slot structures. Through the arrangement of the rollers 515, it can play a role in supporting the silo panel 2, and at the same time, it can also reduce the friction between the sleeve 504 and the fluent strip rack 507, facilitating docking.

[0057] Other structures are the same as those in Embodiment 2 and will not be elaborated here.

[0058] Working principle:

[0059] When the cart 3 is docked with the silo 1 and the silo panel 2: First, push the cart 3 to the positions of the silo 1 and the silo panel 2. Adjust the height of the fluent strip rack 507 through the lead screw 509, so that the pin blocks 513 on the two fluent strip racks 507 correspond to the through holes of the sleeve 504, facilitating the insertion of the pin column for fixation, and the step structures on the lower surface of the sleeve 504 contact the rollers 515 in the slot structures. Insert the pin column between the pin block 513 and the sleeve 504 through the through hole to temporarily fix the cart 3 and the silo panel 2, and push the cart 3 to the filling machine workbench surface 4.

[0060] When the filling machine workbench surface 4 is docked with the silo panel 2: Push the cart 3 close to the filling machine workbench surface 4, and align the threaded push rod 505 on the silo panel 2 with the fixed pin shaft 502 under the filling machine workbench surface 4. Rotate the handwheel 506 to make the threaded push rod 505 dock with the fixed pin shaft 502 and connect in place.

[0061] The trolley 5 leaves the silo panel 2: After the threaded push rod 505 is docked with the fixed pin shaft 502, the silo panel 2 is fixedly connected to the filling machine workbench surface 4. At this time, the pin block 513 and the pin column fixed on the sleeve 504 are pulled out, so that there is no fixed connection between the trolley 3 and the silo panel 2. Pull the trolley 3 backward. During the rolling of the flow bar rack 507 and the sleeve 504, the trolley 3 leaves the silo panel 2.

[0062] If the subsequent filling is completed, the trolley 3 is pushed to the silo panel 2 for further docking. The filling machine workbench surface 4 and the silo panel 2 are separated by using the handwheel 506, and the next silo 1 is replaced to achieve quick change.

[0063] The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. Any equivalent transformation or modification made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
