Description

Technical Field

[0001] The invention relates to the technical field of filling, in particular to a multi-dimensional fixed-point and quantitative filling process of a colloid film sticker. Background Art

[0002] The multi-dimensional fixed-point quantitative filling process of colloidal film stickers is an advanced production technology that achieves efficient and accurate production by precisely controlling the amount and position of the glue liquid. The process adopts automated operation, reduces manual intervention, and improves production efficiency and product quality. This process has the advantages of accurate ratio, uniform mixing, precise positioning, and strong versatility. It is widely used in various production fields that require precise control of the amount of glue liquid, such as electronics, medical, food, etc.

[0003] The patent application number CN202010975091.6 discloses an energy-saving and environmentally friendly manual quantitative filling device for cosmetic filling, including a base, on which a driving member is movably plugged, and a driving shaft is fixedly connected to the lower end of the driving member, and a slider is symmetrically slidably connected to the driving shaft. The energy-saving and environmentally friendly manual quantitative filling device for cosmetic filling uses a driving member to drive a connecting rod and a limiting rod on the slider through a driving shaft, and the connecting rod drives the extruding member to move toward the airbag accommodating chamber to achieve the filling of the cosmetic raw materials, which not only improves the filling quality of the cosmetics, but also has the advantages of energy saving and environmental protection. In addition, the scope of application of the device is relatively wide.

[0004] The existing colloid film fixed-point filling equipment needs to rely on the operator's experience and skills to change the position of the injection head at the bottom of the injection tube when adjusting the position of the injection head to adapt to different film spacings. Manual adjustment not only reduces the flexibility and adaptability of the equipment but also may cause inaccurate positioning problems, affecting the filling accuracy. In addition, when the injection head needs to be replaced or maintained, it is necessary to manually disassemble and re-fix the injection head, which increases downtime and affects the overall efficiency of the production line, and reduces the degree of automation of the overall device.

[0005] In view of this, we propose a multi-dimensional fixed-point quantitative filling process for colloidal membrane patches. Summary of the invention

[0006] The purpose of the present invention is to provide a multi-dimensional fixed-point quantitative filling process for a colloid film patch to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A multi-dimensional fixed-point quantitative filling process of a colloid film patch comprises the following steps:

[0009] S1. First, the operator controls the two motors in the position adjustment group through the controller in the adjustment device to move the point correction device to the top of the conveyor belt of the blister packaging machine;

[0010] S2. Then, the operator controls the driving motor in the driving mechanism to rotate clockwise according to the axial spacing of the film stickers on the conveyor belt of the blister packaging machine, thereby driving the rotating shaft to rotate;

[0011] S3, after the rotating shaft rotates, the worm drives the upper and lower worm gears to rotate, which drives the outer rings at the left and right ends of the worm gears to rotate, and then drives the upper two ratchet gears to rotate through a number of ratchets on the inner side of the upper outer ring;

[0012] S4, after the two groups of ratchets on the top rotate, the rotating rod is driven to rotate, which in turn drives the second reciprocating screw to rotate, and then drives the moving cross bar to move horizontally, so that the plurality of clamping mechanisms move inside the guide groove, thereby changing the axial spacing of the plurality of clamping mechanisms;

[0013] S5. Subsequently, the operator further controls the driving motor to rotate counterclockwise according to the radial spacing of the plurality of film stickers, and allows the plurality of ratchets on the inner side of the outer ring below to drive the two sets of ratchets below to rotate;

[0014] S6, after the two groups of ratchets at the bottom rotate, the first reciprocating screw is driven to rotate, and the positions of the two groups of fixed frames on the left and right are driven to move, thereby changing the radial spacing of the plurality of groups of clamping mechanisms;

[0015] S7. After that, after the blister packaging machine conveys a number of film stickers to the bottom of the point correction device, the colloid conveyor is started to inject a certain amount of colloid into the surface of the film sticker through the glue injection tube, and then the film sticker is sealed and packaged by the packaging mechanism on the right side of the blister packaging machine;

[0016] S8. Subsequently, when the operator inspects and maintains the entire device or needs to replace the injection hose, the two sets of movable horizontal bars are moved toward the direction of the fixed rack by driving the motor;

The bottom surface of the limiting protrusion 344 is welded with a pressure spring 345 whose other end is fixed to the hole wall of the placement hole 3411. The elastic force provided by the pressure spring 345 pushes the limiting protrusion 344 to move in the direction of the rotating ring tooth 342.

[0091] Furthermore, when the two groups of movable horizontal bars 336 move toward the direction of the fixed rack 334 respectively, the rotating ring tooth 342 will rotate after contacting the fixed rack 334, causing the position of the protruding rod on the top of the clamping ring 343 to change inside the arc groove 3420, and then shrink into the inside of the cylinder wall slide groove 3410, thereby loosening the injection head at the bottom of the injection tube 350. The limiting protrusion 344 bounces into the inside of the limiting hole 3421 under the elastic force of the pressure spring 345, which is used to ensure that the position of the rotating ring tooth 342 will not rotate when it is not in contact with the fixed rack 334.
