Detailed implementation manners

[0025] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with specific embodiments.

[0026] It should be noted that unless otherwise defined, the technical terms or scientific terms used in the present utility model should have the ordinary meanings understood by those with ordinary skills in the field to which the present utility model belongs. The "first", "second" and similar words used in the present utility model do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "including" or "comprising" mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects. Words such as "connected" or "linked" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Upper", "lower", "left", "right", etc. are only used to represent relative position relationships, and when the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0027] In the first aspect of the present utility model, a paste filling mechanism is proposed, as Figures 1 to 5 shown,

[0028] A paste filling mechanism includes a frame 1 and a conveying mechanism 2 provided on the frame 1. It also includes a pressing component 3. A connecting frame 31 is provided at the output end of the pressing component 3. A number of discharging heads 4 are arranged and distributed on the connecting frame 31, and a displacement driving component 5 is provided on the connecting frame 31.

[0029] The discharging heads 4 are divided into a fixed discharging head 41 and multiple movable discharging heads 42. The fixed discharging head 41 at one end of the distribution chain is detachably connected to the connecting frame 31. A sliding plate group 51 is provided at the output end of the displacement driving component 5, and the displacement driving component 5 is in transmission connection with the sliding plate group 51. The movable discharging heads 42 are detachably connected to the sliding plate group 51.

[0030] In this embodiment, the conveying mechanism 2 is preferably a plate chain conveyor but is not limited thereto. The conveying mechanism 2 conveys the cans 8 distributed on the plate chain along its length direction. The cans 8 will be in batches of multiple in the feeding area, and the number of discharging heads 4 in the feeding area is also the same as the number of cans 8 in the corresponding area. The paste material is filled into the cans 8 through the discharging heads 4. Here, it is exemplified that there are four discharging heads 4 in the feeding area. Since the four discharging heads 4 are arranged in a line, and the number of cans 8 in the feeding area is also four, when any one of the two middle discharging heads 4 is damaged, or both discharging heads 4 are damaged, this will cause a missed filling phenomenon. Therefore, the damaged discharging head 4 needs to be disassembled for timely repair.

[0031] For the above problems, the staff needs to remove the damaged discharging head 4. At this time, the layout formed by the multiple discharging heads 4 will be in the form of Figures 3 to 5 the three layouts shown. The staff can start the displacement driving component 5 to control the sliding plate group 51 to move along the length direction of the connecting frame 31, so that the remaining three discharging heads 4 or two discharging heads 4 are close to each other, so as to re-form a continuously arranged discharging head 4. Here, it is exemplified that only one discharging head 4 is damaged and removed. Then, for the next filling task, the sensor 6 provided on the conveying mechanism is used for counting. The sensor 6 is a mature existing technology and will not be elaborated here, so as to ensure that the limiting mechanism 7 is opened for release after every three cans 8 are filled, and the conveying mechanism 2 continues to convey all the cans 8 on the plate chain. According to the above method, the problem of the production line shutdown caused by removing and repairing the damaged discharging head 4 can be avoided.

[0032] As an implementation manner, as Figure 2 shown, further:

[0033] The pressing-down assembly 3 includes a fixing plate 32 provided on the frame 1 and a single-axis cylinder 33 fixedly provided on the fixing plate 32. Moreover, the output shaft of the single-axis cylinder 33 is connected to the top of the connecting frame 31. The top of the connecting frame 31 is symmetrically provided with limiting rods 34, and the limiting rods 34 penetrate through the fixing plate 32 and are slidably connected thereto.

[0034] As an implementation manner, as Figures 6 to 9 shown, furthermore:

[0035] The sliding plate group 51 includes a main plate body 511. One end of the connecting frame 31 forms a sleeve 311. The outside of the sleeve 311 is for connecting the fixed-type discharge head 41. The main plate body 511 is slidably connected to the sleeve 311. One end of the main plate body 511 is an installation part 5111 for connecting the movable-type discharge head 42. The other end of the main plate body 511 is provided with a limiting plate 5112.

[0036] The sliding plate group 51 further includes a secondary plate body 512 for connecting the movable-type discharge head 42. A through groove is formed in the main plate body 511, and the through groove is used to accommodate the secondary plate body 512. Rolling bodies 5121 are provided on both sides of the secondary plate body 512. A side cover plate 312 is detachably installed on the connecting frame 31. The rolling bodies 5121 located on both sides of the secondary plate body 512 are respectively in contact with the inner wall of the connecting frame 31 and the side cover plate 312.

[0037] A stop block 313 is provided on the inner wall of the sleeve 311, and the stop block 313 is used to block the rolling body 5121 to stop the movement of the secondary plate body 512.

[0038] The displacement driving mechanism includes a rack 52 fixedly provided at the bottom of the main plate body 511, and a servo motor 53 fixedly installed outside the sleeve. A gear 54 is provided on the output shaft of the servo motor 53, and the gear 54 meshes with the rack 52.

[0039] In this embodiment, the number of secondary plate bodies 512 is the same as the number of the discharge heads 4 in the middle part of the 4 groups of discharge heads. When it is found that a single discharge head 4 at a certain middle position is damaged, the staff removes the side cover plate 312, then removes the damaged discharge head 4 from the corresponding secondary plate body 512, and finally takes out the corresponding secondary plate body 512 and reinstalls the side cover plate 312; the side cover plate 312 is used to limit the secondary plate body 512 to be in the through groove to prevent it from coming out.

[0040] At this time, only one of the auxiliary plate body 512 and its corresponding discharge head 4 inside the accommodation groove remains. Next, start the servo motor 53. The servo motor 53 drives the gear 54 to rotate through the output shaft. The gear 54 drives the main plate body 511 to move through the rack 52. The main plate body 511 drives one of its discharge heads 4 to move towards the third discharge head 4 mounted on the sleeve 311. And during the movement of the main plate body 511, it will drive the second discharge head 4 and its corresponding auxiliary plate body 512 to move by being wrapped through the through groove. However, after the rolling body 5121 on the auxiliary plate body 512 is blocked by the stop block 313, the remaining three discharge heads 4 will form a continuous arrangement state again; the rolling body 5121 is a roller but is not limited thereto.
