[0048] The present embodiment provides a filling quantity control device and a plunger filling machine, the plunger filling machine comprises a material storage barrel, a plurality of filling valves 100 and the filling quantity control device, the material storage barrel contains materials to be filled, the filling valves 100 can move along the circumferential direction of the guide rail mechanism 1, and the filling valves 100 are connected with the material storage barrel. The filling quantity control device comprises a guide rail mechanism 1, a support member 2 and a drive mechanism 3, the guide rail mechanism 1 is rotatably matched with the support member 2, the output end of the drive mechanism 3 is connected with the guide rail mechanism 1, and under the driving action of the drive mechanism 3, the guide rail mechanism 1 can be partially raised, so that the filling valve 100 can achieve quantitative filling of the materials to be filled in the process of the circumferential movement of the guide rail mechanism 1.

[0049] It should be noted that the filling valve 100 in the present application may adopt the plunger-type filling valve in the prior art, and the structure and principle of the plunger-type filling valve are conventional technologies for those skilled in the art and will not be described in detail here.

[0050] The filling volume control device is described in detail below:

[0051] The filling volume control device is used to control the filling volume of the filling valve 100, wherein a plurality of filling valves 100 are arranged on a mounting plane, such as Figure 1-Figure 5As shown, the guide rail mechanism 1 has a guide groove 11 arranged in an annular shape, and the plunger rollers 1001 of the filling valves 100 are arranged in the guide groove 11. The guide rail mechanism 1 has a first connection position 12 and a second connection position 13. The support member 2 is rotatably connected to the first connection position 12 through a pivot 4. The output end of the driving mechanism 3 is connected to the second connection position 13. The driving mechanism 3 is configured to drive the guide rail mechanism 1 to rotate around the pivot 4 so that the guide rail mechanism 1 is arranged at an angle with the installation plane.

[0052] When the driving mechanism 3 is started, it can drive the guide rail mechanism 1 to rotate around the pivot 4, so that the guide rail mechanism 1 is set at an angle with the installation plane. As the filling valve 100 located at the lowest point of the guide rail mechanism 1 moves circumferentially along the guide rail mechanism 1 to the highest point of the guide rail mechanism 1, the plunger roller 1001 of the filling valve 100 will move along the inclined guide groove 11 accordingly, thereby generating a displacement in the vertical direction, thereby achieving the purpose of controlling the filling volume; and, the height difference between the lowest and highest points of the guide rail mechanism 1 is proportional to the filling volume. Therefore, when the filling volume needs to be adjusted, it is only necessary to change the parameters of the driving mechanism 3 to change the value of the angle between the guide rail mechanism 1 and the installation plane, that is, to change the height difference between the lowest and highest points of the guide rail mechanism 1, so as to achieve the adjustment of the filling volume.

[0053] This filling volume control device abandons the complex mode of individually configuring a cylinder for each filling valve 100 to control the filling volume. The filling volumes of several filling valves 100 can be uniformly controlled through one driving mechanism 3, thereby improving the efficiency of the filling operation and reducing the production cost. The filling volume can be adjusted by adjusting the parameters of the driving mechanism 3, without the need to individually adjust each filling valve 100, saving adjustment time and labor costs.

[0054] Specifically, Figure 1 , Figure 2 As shown, the guide rail mechanism 1 includes two guide rails 14 and a fixing assembly 15 . The two guide rails 14 are annular structures. The two guide rails 14 are parallel and spaced apart to form a guide groove 11 . A plurality of fixing assemblies 15 are spaced apart circumferentially around the guide rails 14 . The fixing assemblies 15 are used to fix the two guide rails 14 .

[0055] In this embodiment, when the plunger roller 1001 is accommodated in the guide groove 11, the wheel surface of the plunger roller 1001 fits against both guide rails 14, which can not only ensure the stable movement of the filling valve 100 relative to the guide rail mechanism 1, but also reduce the friction between the filling valve 100 and the guide rail 14 during movement.

[0056] Furthermore, if Figure 2As shown, in the vertical direction, the upper guide rail 14 has a notch 141 for the filling valve 100 to be installed in the guide groove 11. When installing the filling valve 100, the plunger roller 1001 of the filling valve 100 can be moved from the notch 141 from top to bottom to a position abutting against the lower guide rail 14, and then slide along the circumference of the guide rail 14 to insert the plunger roller 1001 of the filling valve 100 into the guide groove 11 formed by the two guide rails 14.

[0057] Specifically, Figure 2 , Figure 4 As shown, the fixing assembly 15 includes a fixing member 151 and a locking member. The fixing member 151 includes an extension portion 1511 and fixing portions 1512 arranged at an angle at both ends of the extension portion 1511. The extension portion 1511 extends along the distribution direction of the two guide rails 14. The two fixing portions 1512 are correspondingly located on the side of the two guide rails 14 away from the guide groove 11. At least one locking member passes through the fixing portion 1512 and the corresponding guide rail 14 to fix the two. The extension portion 1511 extends along the distribution direction of the two guide rails 14, that is, the extension portion 1511 matches the layout of the guide rails 14, ensuring that the two fixing portions 1512 arranged at both ends of the extension portion 1511 can correspond to the two guide rails 14. The fixing portion 1512 is fixedly connected to the corresponding guide rail 14 using the locking member, and the two guide rails 14 can be locked and fixed into a whole through the fixing assembly 15. The number and layout of the fixing components 15 can be adjusted according to the layout and structure of the guide rail 14, and the adaptability is strong; the fixing and disassembly can be completed by the locking piece, and the assembly process is faster.

[0058] In this embodiment, the locking member is a bolt. In other embodiments, the locking member may also be a screw. It should be noted that any structure in the prior art that can achieve fixed connection between the fixing portion 1512 and the guide rail 14 can be used as the locking member in this embodiment.

[0059] Specifically, Figure 1 , Figure 2 As shown, a swivel seat 5 is provided at the first connection position 12 of the guide rail mechanism 1, and the support member 2 is rotatably connected to the swivel seat 5 via a pivot 4. The support member 2 is rotatably connected to the swivel seat 5 via the pivot 4, so that the guide rail mechanism 1 can be rotatably pivoted to the support member 2.

[0060] Specifically, Figure 1 , Figure 2As shown, the number of first connection positions 12 is two, the number of support members 2 is also two, and the two support members 2 are connected to the two first connection positions 12 in a one-to-one correspondence through the pivot 4. And / or, the number of second connection positions 13 is two, the number of drive mechanisms 3 is also two, and the output ends of the two drive mechanisms 3 are connected to the two second connection positions 13 in a one-to-one correspondence. By setting two support members 2 to support the guide rail mechanism 1, the guide rail mechanism 1 can be prevented from shaking, so as to ensure the overall stability and reliability of the guide rail mechanism 1 and ensure the precise control of the filling amount; by sharing the weight and force of the guide rail mechanism 1 with the two support members 2, the load borne by the support member 2 can be reduced, and the service life of the support member 2 can be extended. By coordinating the control of the guide rail mechanism 1 with the two drive mechanisms 3, the precise control of the movement of the guide rail mechanism 1 can be achieved, the movement accuracy of the guide rail mechanism 1 can be improved, and the stable lifting or lowering of the guide rail mechanism 1 can be ensured; and the two drive mechanisms 3 can also serve as a support for the guide rail mechanism 1, and cooperate with the support members 2 to stably support the guide rail mechanism 1.

[0061] In this embodiment, the distance between the two first connection positions 12 is smaller than the diameter of the circle where the guide groove 11 is located, and the distance between the two second connection positions 13 is smaller than the diameter of the circle where the guide groove 11 is located. In this way, the four connection positions, namely the two first connection positions 12 and the two second connection positions 13, can serve as four support positions, which can ensure that the overall force of the guide rail 14 is balanced, avoid shaking of the guide rail 14, and improve the stability of the movement of the filling valve 100.

[0062] Specifically, Figure 1 , Figure 2 As shown, the driving mechanism 3 includes a driving member 31 and a lifting member 32. The output end of the driving member 31 is connected to the lifting member 32. The driving member 31 is configured to drive the lifting member 32 to move in the vertical direction. The lifting member 32 is connected to the second connection position 13. When the driving member 31 drives the lifting member 32 to move up and down, the lifting member 32 can drive the second connection position 13 of the guide rail mechanism 1 to move up and down. Since the first connection position 12 of the guide rail mechanism 1 is rotatably connected to the support member 2, the motion trajectory of the guide rail mechanism 1 is expressed as a rotation around the pivot 4 as the rotation axis, so that the guide rail mechanism 1 is set at an angle with the installation plane.

[0063] Furthermore, if Figure 1 , Figure 2 and Figure 5As shown, a transfer structure 6 is provided at the second connection position 13 of the guide rail mechanism 1, and the lifting member 32 has a long hole 321 extending in the horizontal direction. The transfer structure 6 is movably installed in the long hole 321 along the extension direction of the long hole 321. When the guide rail mechanism 1 rotates around the pivot 4 as the rotation axis, the transfer structure 6 connected to the second connection position 13 of the guide rail 14 will produce a certain displacement in the horizontal direction. By setting the transfer structure 6 to be able to move in the horizontal direction relative to the long hole 321 of the lifting member 32, the connection between the transfer structure 6 and the lifting member 32 can be prevented from being broken, thereby extending the service life of the filling volume control device.

[0064] Specifically, Figure 5 As shown, the adapter structure 6 includes an adapter 61 and a connecting member 62. The adapter 61 includes a first adapter portion 611 and a second adapter portion 612. The first adapter portion 611 is connected to the guide rail mechanism 1. The connecting member 62 is movably arranged in the long hole 321, and the second adapter portion 612 is connected to the connecting member 62. Such a configuration can facilitate the connection between the adapter structure 6 and the guide rail mechanism 1 and the driving mechanism 3, thereby improving the assembly efficiency.

[0065] In this embodiment, there are two first adapter parts 611, and the two first adapter parts 611 are arranged in parallel and at intervals, wherein one first adapter part 611 is connected to the top of the guide rail mechanism 1, and the other first adapter part 611 is connected to the bottom of the guide rail mechanism 1. Such an arrangement can ensure the stability of the connection between the adapter structure 6 and the guide rail mechanism 1, thereby ensuring the stability of the movement of the filling valve 100 and the quantitative filling accuracy. There are two second adapter parts 612, and the two second adapter parts 612 are arranged between the two first adapter parts 611, that is, the two ends of the second adapter part 612 are respectively connected to the two first adapter parts 611. After the connecting member 62 passes through one second adapter part 612, it is inserted into the long hole 321 of the lifting member 32, and then passes through the other second adapter part 612. Among them, the connecting member 62 can be selected from screws or bolts, which is not limited in this embodiment.

[0066] In this embodiment, the driving member 31 is a motor; in other embodiments, the driving member 31 may also be a hand wheel or a cylinder. It should be noted that any structure in the prior art that can drive the lifting member 32 to rise and fall can be used as the driving member 31 in this embodiment, and this embodiment does not limit this.

[0067] Specifically, Figure 1-Figure 3 As shown, the filling quantity control device further comprises a mounting plate 7 , on which the guide rail mechanism 1 and the driving mechanism 3 are both arranged.

[0068] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
