Abstract
Description
Technical Field
[0001] This technical solution relates to the field of thermos cup manufacturing equipment technology, specifically to a spouting device and a thermos cup spouting machine. Background Technology
[0002] Stainless steel thermos cups are made of double-layered stainless steel, both inside and out. Therefore, during the production process, the mouths of the inner liner and outer shell must first be aligned to form the cup body (i.e., the spout). Then, the spout of the cup body is welded to integrate the inner liner and outer shell. In the past, thermos cup manufacturing typically involved manually hammering the spouts of the inner liner and outer shell to achieve this level of fit. This method heavily tests the worker's skill and efficiency, and the manual hammering process resulted in significant errors in the fit, leading to the inner liner being misaligned and touching the outer shell after welding, or to incomplete welds, directly affecting product quality.
[0003] Chinese patent CN221755267U discloses a multi-station thermos cup spout fitting machine. When this spout fitting machine is working, if the inner liner and outer liner are not placed horizontally and stably, it can only press the inner liner and outer liner at the same angle, which makes it impossible to guarantee the neatness of the spout fitting. Therefore, there is an urgent need for a spout fitting machine that can fit the spout when the inner liner and outer liner are not placed stably. Summary of the Invention
[0004] The purpose of this technical solution is to provide a splicing device and a thermos cup splicing machine. By rotating the inner and outer liner through a rotating mechanism, the pressing mechanism can splice the inner and outer liner multiple times at different angles, thus solving the problem of low splicing uniformity in the original equipment.
[0005] The purpose of this technical solution is achieved as follows:
[0006] A spout fitting device includes: a mounting frame; a clamping mechanism including a clamping plate movably disposed on the mounting frame; and a rotating mechanism including a rotating plate rotatably disposed on the mounting frame; wherein the rotating plate has a placement position formed thereon for placing an inner liner and an outer liner of a thermos cup; the rotating plate is used to drive the inner liner and the outer liner to rotate to achieve spout fitting at different angles.
[0007] Preferably, the clamping mechanism includes: a clamping drive member disposed on the mounting bracket; a clamping guide rod disposed at the output end of the clamping drive member; and a clamping plate disposed at the lower end of the clamping guide rod and used to movably abut against the upper ends of the inner liner and the outer liner.
[0008] Preferably, the clamping mechanism further includes: a plurality of clamping guide posts, which pass through the mounting frame and surround the clamping guide rod; and a clamping connecting plate, which is disposed at the lower end of the clamping guide rod; wherein the clamping plate is disposed below the clamping connecting plate via a clamping bearing.
[0009] Preferably, the upper end of the pressing plate is provided with a plug hole, and the lower end of the pressing connecting plate is provided with a plug post; when the pressing plate is placed on the pressing connecting plate, the plug post is placed in the plug hole.
[0010] Preferably, the rotating mechanism includes: a rotating drive member disposed on the mounting frame; a rotating connecting part disposed at the output end of the rotating drive member and having rotating gear teeth; and a rotating plate having a rotating disk at its lower end, wherein rotating gears are disposed around the rotating disk; wherein the rotating gear teeth and the rotating gears mesh with each other.
[0011] Preferably, the rotating mechanism further includes: a rotating slide seat disposed on the mounting bracket; and a rotating slider slidably disposed on the rotating slide seat; wherein the rotating connecting portion is disposed on the rotating slider.
[0012] Preferably, the rotating plate is mounted on the mounting frame via a rotating base.
[0013] A thermos cup splicing machine includes: a frame; and a splicing device disposed on the frame.
[0014] The key and beneficial technical effects of this technical solution compared to existing technologies are:
[0015] 1. The rotating mechanism designed in this technical solution can drive the inner and outer liner to rotate simultaneously. When the rotation reaches the designated position, the pressing mechanism vertically lifts and lowers to press the inner and outer liner together. The rotating mechanism can achieve different angles of fitting to improve the neatness of the inner and outer liner.
[0016] 2. The rotating mechanism designed in this technical solution controls the rotation of the rotating plate through gear transmission, converting the linear movement of the output end of the rotating drive into the rotation of the rotating plate. This allows for precise and stable control of the rotation angle of the rotating plate, facilitating the streamlined operation of the patching machine. Attached Figure Description

[0021] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.
[0022] like Figure 1 As shown, a fitting device includes a mounting frame 1, a clamping mechanism 2, and a rotating mechanism 4. The mounting frame 1 is used to mount the clamping mechanism 2 and the rotating mechanism 4. The mounting frame 1 is equipped with a platform for placing the rotating mechanism 4. The clamping mechanism 2 is located directly above the rotating mechanism 4. In actual use, the inner liner and the outer liner need to be placed above the rotating mechanism 4, and then the clamping mechanism 2 is used to clamp the inner liner and the outer liner. After the first clamping, the clamping mechanism 2 rises, the rotating mechanism 4 rotates at a certain angle, and then the clamping mechanism 2 falls down to clamp again. This can ensure a high degree of alignment between the inner liner and the outer liner, thereby avoiding the impact of misalignment between the inner liner and the outer liner on the fitting.
[0023] Specifically, the clamping mechanism 2 moves vertically up and down on the mounting frame 1, and the rotating mechanism 4 moves in a circular motion on the mounting frame 1. The angle of each rotation can be set by the program. In actual use, the optimal angle of each rotation is 120° or 180°. This allows the clamping mechanism 2 to work multiple times to improve the neatness of the inner liner inlet and outer liner outlet.
[0024] like Figure 2 As shown, the clamping mechanism 2 includes a clamping drive 6, a clamping guide rod 7, and a clamping plate 3. The clamping guide rod 7 is used to connect the clamping drive 6 and the clamping plate 3. The clamping drive 6 can be set as a servo motor or other power source. The servo motor can accurately control the movement path of the clamping plate 3, which can ensure the neatness of the fitting and also ensure that it will not be over-clamped and damage the inner and outer liner. The clamping plate 3 can be set as a column that fits the diameter of the outer liner to ensure full coverage of the inner and outer liner.
[0025] Furthermore, to ensure the stability of the clamping plate 3 during the clamping process, we also set several clamping guide posts 8 on the mounting frame 1. The clamping guide posts 8 are used to assist the movement of the clamping guide rod 7. The clamping guide posts 8 are movably inserted into the mounting frame 1 to ensure the vertical movement of the clamping guide rod 7. We also set a clamping connecting plate 9 and a clamping bearing 10 between the clamping guide rod 7 and the clamping plate 3 to improve the connection stability between the clamping guide rod 7 and the clamping plate 3. In addition, the clamping plate 3 is detachably set on the clamping connecting plate 9. The upper end of the clamping plate 3 is provided with a plug hole 11, and the lower end of the clamping connecting plate 9 is provided with a plug post 12. When the clamping plate 3 is set on the clamping connecting plate 9, the plug post 12 is placed in the plug hole 11. This allows for quick replacement of clamping plates 3 with different outer diameters to adapt to inner and outer liner specifications.
[0026] like Figure 3 As shown, the rotating mechanism 4 includes a rotating drive component 13, a rotating connecting part 14, and a rotating plate 5. The rotating connecting part 14 is used to connect the rotating drive component 13 and the rotating plate 5. The rotating drive component 13 can be configured as a servo motor or other power source. The servo motor can accurately control the movement path of the rotating connecting part 14 to ensure the predetermined rotation angle of the rotating plate 5. The rotating connecting part 14 is located at the output end of the rotating drive component 13 and can move horizontally back and forth. A rotating gear 15 is provided on the end side of the rotating connecting part 14. A rotating disk 16 with a rotating gear 17 is provided at the lower end of the rotating plate 5. The rotating gear 15 and the rotating gear 17 mesh with each other to realize the rotation of the rotating plate 5 driven by the rotating drive component 13.
[0027] Furthermore, in order to ensure the stability of the rotating mechanism 4 during operation, a rotating slide 18 and a rotating slider 19 are provided below the rotating connection part 14. The rotating connection part 14 is mounted on the rotating slide 18 via the rotating slider 19 to ensure the stability of the horizontal movement of the rotating connection part 14. A rotating base 20 is provided below the rotating plate 5, and the rotating plate 5 is mounted on the mounting frame 1 via the rotating wheel 16.
[0028] like Figure 1 As shown, a thermos cup splicing machine includes a frame and several splicing devices, which can simultaneously splice multiple thermos cups.
