Description

Technical Field

[0001] This utility model relates to the field of packaging equipment for bottled food such as wine and beverages, and specifically to the field of capping machine structure. Background Technology

[0002] A capping machine is a device used to cap bottled products. It uses a rotating cam mechanism at the top to drive the capping mechanism to cap the bottled products. The capping method of the capping machine has a significant impact on its accuracy and efficiency. With the increasing requirements for packaging accuracy and cap breakage rate of bottled products, the original capping methods (such as cap container capping method, cap slide capping method, etc.) can no longer meet the accuracy and cap breakage rate requirements of the market. The original capping methods are prone to problems such as misalignment between the cap and the capping device, misalignment between the cap and the bottle mouth, poor accuracy, cap jamming and blockage of the cap slide, affecting equipment efficiency, and mismatch between cap supply speed and capping speed, which greatly affects production efficiency. Utility Model Content

[0003] To address the above problems, this utility model proposes a cap-removing mechanism for a capping machine, which can effectively match the cap supply speed with the capping speed, thus avoiding problems such as cap jamming, blockage, and misalignment.

[0004] The technical solution of this utility model is as follows: the capping machine includes a frame, a turntable and several capping devices. The turntable rotates under the drive of a rotational power source, and the several capping devices are evenly distributed along the circumference of the turntable.

[0005] The cap-removing mechanism includes a cap slide assembly 5, a cap-removing plate 1, a rotating shaft 3, a transmission gear 4, and a retainer 2. The retainer 2 is fixedly connected to the frame of the capping machine. The cap slide assembly 5 is fixedly installed on one side of the retainer 2 for accommodating caps. The rotating shaft 3 is rotatably connected to the retainer and is arranged parallel to the capping device. An arc-shaped guide slide is also fixedly installed at the bottom of the retainer 2. The outlet at the bottom of the cap slide assembly 5 is connected to the guide slide. The cap-removing plate 1 is fixedly connected to the bottom end of the rotating shaft 3. The transmission gear 4 is fixedly fitted in the middle of the rotating shaft 3 to drive the rotating shaft 3 and the cap-removing plate 1, so that the three rotate synchronously.

[0006] The edge of the lid-removing disc 1 has multiple toothed grooves evenly distributed circumferentially for pushing the lid; the edge of the transmission gear 4 has multiple transmission grooves evenly distributed circumferentially for matching the lid-pressing device, and the transmission gear 4 is engaged with the lid-pressing device.

[0007] In this way, on the one hand, after the cap passes through the cap slide assembly 5 and enters the arc-shaped guide slide, it is pushed by the toothed groove on the cap-retrieving plate 1 and slides steadily forward along the guide slide until it is taken away by the capping machine. On the other hand, each time a capping device rotates, the transmission gear 4 will also drive the cap-retrieving plate to rotate once. Even though the cap-retrieving plate is driven to rotate by the rotating capping device through the transmission shaft and transmission gear, orderly cap distribution can be achieved without the need for an additional power source. Specifically, the cap-retrieving plate and the capping device have a 1:1 transmission ratio, and the rotation speed of the cap-retrieving plate is always consistent with that of the capping device, enabling continuous, efficient, and accurate cap supply. Furthermore, compatibility with various cap models can be achieved by changing the guide slide and the cap-retrieving plate.

[0008] Furthermore, the cap removal mechanism also includes an air blowing device 8 fixedly installed next to the outlet at the bottom of the cap slide assembly 5, with the air outlet of the air blowing device 8 facing the inlet of the guide slide.

[0009] Furthermore, there are two air blowing devices 8, which are symmetrically distributed on the upper and lower sides of the cover slide assembly 5.

[0010] Furthermore, the cap-removing mechanism also includes a cap-blocking device 9 fixedly installed beside the outlet at the bottom of the cap slide assembly 5. The cap-blocking device 9 includes a linear drive mechanism and a stop. The linear drive mechanism is fixedly installed on the cap slide assembly 5, and its output end is fixedly connected to the stop. The stop extends through the cap slide assembly 5 and into the outlet at the bottom of the cap slide assembly 5. Thus, a cap-blocking device that can be linked with the cap-pressing device allows the cap-removing disc device to remove caps in the corresponding quantity according to the actual cap-pressing speed.

[0011] Furthermore, the gap between the guide slide and the toothed groove is adapted to the cap. This allows the toothed groove of the cap-removing plate to fully constrain the position of the cap, ensuring high positional accuracy of the cap and keeping the cap, capping device, and bottle mouth concentric.

[0012] In operation, the cap enters from the top of the cap slide assembly and is then conveyed to the tangent of the cap-picking disc by gravity and an air blowing device. The rotating disc then distributes the cap to a position directly below the head of the cap-pressing device, completing the cap-picking action. Once the cap is positioned directly below the cap-pressing device, the device picks it up, completing the cap-pressing process. During this process, the cap-picking disc is driven to rotate by the cap-pressing device via a drive shaft and gears, achieving a 1:1 transmission with the device. This eliminates the need for an additional power source, enabling orderly cap distribution. Furthermore, this invention can accommodate various cap models by replacing the guide slide and cap-picking disc. Overall, it offers stable and orderly cap picking, more efficient cap pushing and arrangement, and effectively avoids a series of technical problems caused by misaligned cap installation.

[0022] To clearly illustrate the technical features of this patent, the following detailed description is provided through specific embodiments and in conjunction with the accompanying drawings.

[0023] like Figure 1 As shown, this example discloses a capping method of a capping machine, including a capping plate 1, a cap slide assembly 5, a retainer 2, a rotating shaft 3, a transmission gear 4, an air blowing device 8, and a cap blocking device 9. The retainer 2 is installed on the frame of the capping machine, the rotating shaft 3 is installed on the retainer 2 through bearings, the transmission gear 4 is installed on the upper part of the rotating shaft 3, the capping plate 1 is installed on the lower part of the rotating shaft 3, the air blowing device 8 is installed on the cap slide assembly 5, and the cap blocking device 9 is installed below the cap slide assembly 5. The capping plate 1 rotates by meshing with the capping device through the rotating shaft 3 and the transmission gear 4. The capping device is driven by a motor to perform the capping action.

[0024] The cap enters from the top of the cap slide assembly 5 and is then transported to the tangent of the rotating cap-removing plate 1 by gravity and the air blowing device 8. The rotating cap-removing plate 1 then distributes the cap to the head of the capping device. At this time, the cap-removing action of the cap-removing plate is completed. When the cap is transported to the head of the capping device, the capping device removes the cap and then completes the capping action.

[0025] like Figure 2 , 3The lid shown is constrained within the slide by the cover guide assembly 5 and the cover retainer 9. After being released by the cover retainer 9, the lid is blown into the toothed groove of the cover-retrieving plate 1 by the continuously operating air blowing device 8. Figure 3 , 4 As shown in Figure 6, the lid is then conveyed to the head of the capping device as the capping plate 1 rotates.

[0026] like Figure 5 The transmission gear 4 shown meshes with the outer circle of the capping device and rotates with the capping device, thereby driving the cap-removing plate 1 to rotate through the rotating shaft 3 and ensuring that the rotation of the cap-removing plate 1 and the capping device 6 are synchronized.

[0027] like Figure 6 The sectional view of the cover device 9 shown shows that when the cover slides from the top to the bottom of the cover slide 5, the cover can be controlled to enter the cover picking plate 1 in an orderly manner. The corresponding number of covers can be distributed and delivered according to the actual capping speed in coordination with the cover picking plate 1.

[0028] like Figure 7 When the cover is released after being blocked by the cover-pressing device 9 due to the cover pressing speed, the air blowing device 8 shown can blow the cover into the cover-retrieving plate 1 by means of gravitational potential energy.

[0029] like Figure 4 The diagram shows the lid entering the toothed groove of the lid-retrieving plate 1. The toothed groove of the lid-retrieving plate 1 completely restrains the lid, and as the lid-retrieving plate rotates, it accurately delivers the lid directly below the capping head.

[0030] There are many specific implementation methods for this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of this utility model, and these improvements should also be considered within the protection scope of this utility model.
