Description

Technical Field

[0001] The utility model relates to the technical field of preparation of health care product capsules, in particular to a dispensing mechanism for plastic-sealed membranes in capsule boxes. Background Art

[0002] Capsule extraction equipment is a type of device that uses a capsule structure as an extraction medium. When in use, the device uses a puncture needle to penetrate the sealing membrane at the top of the beverage capsule, injects liquid with a set temperature and pressure into the capsule, and extracts the active ingredients in the capsule contents through pressure immersion extraction to obtain the corresponding beverage.

[0003] A typical capsule structure used in capsule extraction devices includes a rigid or semi-rigid plastic shell with a volume cavity for accommodating the extract contents. The volume cavity surface is open and requires hot-pressing and sealing the open surface with plastic film. Under current technical conditions, to ensure the continuity of the production process of capsule boxes with the above-mentioned characteristic structure, a production method is generally adopted in which a roll of plastic film is continuously hot-pressed and sealed, followed by cutting and shaping steps. However, this production method has several drawbacks. First, due to the diverse sizes and shapes of capsule boxes, production often requires adjusting operating parameters according to the size and shape of the plastic film roll to accommodate capsule boxes of different specifications. This results in frequent replacement and adjustment of equipment when producing the same type of products of different sizes and specifications, increasing operational complexity and production costs. Second, during the sealing process, the plastic film may become misaligned or uneven, which not only causes positional deviation and appearance problems on the printed surface, but also may cause quality problems such as poor sealing. In addition, the error margin reserved in the cutting step may lead to waste of plastic film, thereby increasing material costs. Utility Model Content

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0026] See also Figures 1 to 3 A preferred embodiment of a dispensing mechanism for capsule box plastic-sealed film sheets is disclosed. In this embodiment, the main structure of the dispensing mechanism for capsule box plastic-sealed film sheets is a fixed frame and a dispensing component assembled on the fixed frame. The dispensing component is a detachable structure on the fixed frame. Different sizes and shapes of capsule boxes 3 and corresponding plastic-sealed film sheets 5 can be adapted by disassembling and replacing different dispensing components, thereby realizing rapid switching of different product specifications.

[0027] The fixed frame in the embodiment is an assembling and stabilizing structure, which comprises an assembling part 16 and a structural assembling plate 6, and the assembling part 16 and the structural assembling plate 6 are connected by two vertically arranged guide connecting rods 15. The assembling part 16 is reserved with an assembling structure matched with the production line rack 1 and a fixing part 17, and the fixed frame can be assembled to the side of the corresponding distribution station of the production line rack 1 through the combination of the assembling structure and the fixing part 17. In different embodiments, the corresponding assembling structure and the fixing part 17 can be the combination of a threaded fixing part and a clamping part or a plug-in part. In the embodiment, the corresponding assembling structure is a plug-in structure, and the corresponding fixing part 17 is a threaded fixing part.

[0028] In addition, in order to realize the fine adjustment of the fixed frame at the corresponding assembling position of the production line rack 1, the threaded hole of the corresponding threaded fixing part is a waist-shaped hole to realize the adjustment of the degree of freedom during fine adjustment, so as to facilitate the adjustment of the positional relationship between the distribution mechanism and the production line distribution station and ensure the accurate alignment between the fixed frame and the production line rack 1.

[0029] The corresponding guide connecting rod 15 is formed with a tapering top head 11 with an outer threaded surface at the top, and the structural assembling plate 6 is formed in a T-shaped structure as shown in Figure 2 The structural assembling plate 6 is symmetrically formed with a through hole matched with the tapering top head 11 at both sides of the horizontal edge, the structural assembling plate 6 is positioned and placed at the through hole position, and then the tapering top head 11 is assembled and pressed by using a press nut 12, so as to complete the combined assembly of the structural assembling plate 6 at the top of the guide connecting rod 15.

[0030] The structural assembling plate 6 is reserved with a cylinder assembling position at the middle position of the assembling position of the two guide connecting rods 15 for assembling a cylinder 10, and the cylinder rod 13 of the cylinder 10 is assembled and connected with the movable sliding block 4 at the lower part. The movable sliding block 4 is also a T-shaped structure, and a linear bearing 14 is formed at both sides of the horizontal edge of the T-shaped structure, and the movable sliding block 4 is assembled with the guide connecting rod 15 through the linear bearing 14. The movable sliding block 4 can be driven to move back and forth along the linear direction of the guide connecting rod 15 through the action of the cylinder 10.

[0031] The movable sliding block 4 is equipped with a distribution assembly on the vertical edge of the T-shaped structure, and the structural assembling plate 6 is previously provided with a matched vertical through hole at the assembling position corresponding to the distribution assembly, so as to facilitate the operation of the distribution assembly. The distribution assembly is used for distributing the plastic packaging film 5 to the designated position, which comprises a cylindrical material box or a cylindrical material structure. In the embodiment, a cylindrical material structure composed of four limiting vertical rods 9 is adopted, and the four limiting vertical rods 9 limit the plastic packaging film 5 with a circular outer contour on the outside, so that multiple plastic packaging films 5 can be stacked in the cylindrical material structure area composed of the four limiting vertical rods 9.

[0032] A circular movable pressing block 8 slightly smaller than the outline of the plastic sealing film sheet 5 is placed on the surface of the multiple plastic sealing film sheets 5 placed in the cylindrical material feeding structure region composed of four limiting vertical rods 9. The movable pressing block 8 is an iron pressing block, and a magnetic counterweight block 7 with the same cross-sectional size is connected to the lower surface of the movable pressing block 8 by magnetic attraction.

[0033] In addition, the two limiting vertical rods 9 opposite in position among the four limiting vertical rods 9 are connected by an elastic material connecting block 18 at the bottom, and an elastic hook 19 is connected to the elastic material connecting block 18. The elastic hook 19 can fix the multiple plastic sealing film sheets 5 in the cylindrical material feeding structure region on both sides as shown. Figure 3

[0034] In use, the distribution mechanism of the embodiment needs to first use the feeding disc 2 to send the capsule box 3 to be packaged to the distribution station of the production line, and the corresponding capsule box 3 is located directly below the cylindrical material feeding structure region. The corresponding capsule box 3 has a circular top surface slightly smaller than the plastic sealing film sheet 5, and an annular hot-pressing edge with a surface glue is formed on the outer edge of the circular top surface (the outer diameter of the annular hot-pressing edge is within the range of the elastic hook). At this time, the cylinder 10 drives the movable sliding block 4 to press down, so that the plastic sealing film sheet 5 is pressed against the surface of the capsule box 3 under the gravity of the magnetic counterweight block 7 / movable pressing block 8, and is adhered to the glue layer on the annular hot-pressing edge, and when the cylinder 10 drives the movable sliding block 4 to lift, the lowermost plastic sealing film sheet 5 is separated from the fixing of the elastic hook 19 through the adhesive force of the glue layer and the plastic deformation of the plastic sealing film sheet 5, thereby realizing the distribution and single use of the plastic sealing film sheet 5.

[0035] After the distribution of the plastic sealing film sheet 5, the capsule box 3 with the plastic sealing film sheet 5 is continuously sent to the hot-pressing working position by the feeding disc 2, and the subsequent hot-pressing packaging work can be performed. In the hot-pressing working position, the top surface of the capsule box 3 is in contact with the annular hot-pressing edge of the plastic sealing film sheet 5, and heat and pressure are applied by the hot-pressing equipment to make the plastic sealing film sheet 5 and the top surface of the capsule box 3 hot-press and adhere, thereby forming a sealing effect. After hot-pressing is completed, the capsule box 3 continues to move along the production line to perform the next packaging or inspection process.

[0036] In order to adapt to different sizes and shapes of the capsule box 3 and the corresponding plastic sealing film sheet 5, the corresponding elastic hook 19 can realize elastic force adjustment through the elastic material connecting block 18 of different materials to adapt to the deformation extraction force of different plastic sealing film sheets 5. At the same time, by adjusting the weight of the corresponding magnetic counterweight block 7, the force adjustment of the plastic sealing film sheet 5 placed on the surface of the material pile can be realized to adapt to plastic sealing film sheets of different thicknesses and materials. This adjustment mechanism ensures that the plastic sealing film sheet 5 can be uniformly and stably pressed during the distribution process, thereby ensuring that the plastic sealing film sheet 5 distributed each time can be uniformly attached to the surface of the capsule box 3. In addition, by accurately controlling the weight of the magnetic counterweight block 7, the influence of the plastic sealing film sheet 5 edge curling on the hot-pressing packaging effect can also be reduced.​

Those skilled in the art should understand that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention. Furthermore, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications, and / or variations to the present invention, all of which equivalent forms fall within the scope of protection defined by the appended claims.
