Description

TECHNICAL FIELD

[0001] The present application relates to a cup manufacturing method, in particular to a double-layer public cup manufacturing method. BACKGROUND

[0002] The public cup is also called a tea cup, which is a device for containing water, tea soup and other beverages. The traditional metal heat preservation container directly processes the water outlet on the container by stamping, and the lower end of the water outlet of the public cup is in close contact with the inner container and the outer shell, which accounts for a large proportion of the overall cup body, so that the temperature of the beverage in the cup is directly transmitted to the outer shell through the inner container and then radiated outward, which causes the liquid in the cup to cool down too quickly, resulting in a decrease in the heat preservation performance of the public cup.

[0003] The water outlet on the public cup is usually formed by die stamping. During production, the cup body semi-finished product is clamped by a clamping device, and then the lower die is pressed into the cup opening direction to form the water outlet. At this time, the cup wall will not only be subjected to downward pressure, but also be subjected to horizontal impact force, which makes the inner side wall of the water outlet prone to have more burrs and scratches, and thus the production efficiency and product quality of the public cup are affected. Therefore, improvement is needed. SUMMARY

[0004] The present application provides a new double-layer public cup manufacturing method to solve the defects in the prior art that the contact area between the outer shell and the inner container is too large, resulting in the failure of the vacuum layer and the decrease in the heat preservation performance of the public cup, and that the use of the lower die to stamp the water outlet in the vertical direction causes the inner wall of the cup body to have wire drawing, thereby reducing the production efficiency and product quality of the public cup.

[0098] More specifically, when the public cup is punched for the pouring spout, as shown in Figures 6-16 , four steps can be taken.

[0099] When step D1 is performed, as shown in Figure 6 , Figure 7 , Figure 11 , the cup body driving member 22 is started to push the adjusting column 41 upward to the position, then the cup body semi-finished product 100 is sleeved on the positioning block 45 and the welding table 93 is attached to the abutting surface 452.

[0100] When step D2 is performed, as shown in Figures 11-13As shown, the device platform 1 is started to move the clamping assembly 5 to the direction of the positioning block 45, when the lower end of the clamping petals 52 contacts the clamping guide surface 72, the clamping petals 52 are moved to the direction of mutual approach under the action of the clamping guide surface 72 and are folded outside the cup body semi-finished product 100, and the elastic return member 54 is gradually compressed; with the gradual downward movement of the clamping petals 52, the lower end of the clamping petals 52 is placed on the top of the placement table 42 and pushes the adjusting assembly 4 to move downward as a whole to the lower surface of the placement table 42 and the inner side wall of the bottom of the protection cavity 71, at this time, the clamping petals 52 clamp outside the cup body semi-finished product 100, the top of the cup body semi-finished product 100 is inserted into the cup body fixing groove 13, and the elastic return member 54 continues to be compressed, at this time, the fixing of the cup body semi-finished product 100 by the clamping assembly 5 is completed.

[0101] In the embodiment of the present application, the elastic return member 54 is made of cowhide material, so as to cooperate with the clamping guide surface 72 to elastically adjust the clamping petals 52, increase the total height difference of the cup body when the clamping assembly 5 clamps the cup body semi-finished product 100, guarantee the consistency of the mouth of the cup body semi-finished product 100, and improve the accuracy of the adjusting assembly 4 when stamping the pouring spout. At the same time, the structure strength of the bottom of the cup body semi-finished product 100 is enhanced through the groove 841, so that the cup body semi-finished product 100 is not easy to deform when the device platform 1 and the clamping assembly 5 clamp outside the cup body semi-finished product 100.

[0102] When step D3 is performed, as shown in Figures 8-10 , and Figure 15 , the pouring spout driving member 21 is started to move the push rod 43 upward, with the gradual upward movement of the push rod 43, the pouring spout forming block 3 is moved outward under the pushing of the push inclined surface 440, at this time, the side wall of the cup body semi-finished product 100 is deformed under the mutual extrusion of the pouring spout forming block 3 and the shaping groove 51 and forms the pouring spout.

[0103] When stamping, the inner side wall of the inner container 94 only bears transverse pressure, which not only avoids more burrs and scratches on the inner side wall of the pouring spout, but also avoids that the outer shell 84 and the inner container 94 are completely attached after extrusion, and also makes the pouring spout on the cup body 101 have a gap between the outer shell 84 and the inner container 94 relative to the existing public cup pouring spout, thereby reducing the contact area of the outer shell 84 and the inner container 94, making the invalid point of the heat preservation layer formed by the contact of the outer shell 84 and the inner container 94 be located at a higher position of the liquid level inside the cup body 101, avoiding that the liquid surface inside the cup body 101 contacts the invalid point of the heat preservation layer too early, and making the product have better heat preservation performance.

[0104] When step D4 is performed, as shown in Figures 7-13 , Figure 16As shown, after the pouring spout stamping is completed, the equipment platform 1 is first moved upward, and the adjusting assembly 4 is controlled to move upward synchronously with the equipment platform 1 by the cup body driving element 22, the clamping petals 52 are reset to the direction away from each other under the elastic force of the elastic reset element 54 and gradually separated from the clamping guide surface 72 and the outer surface of the cup body 101, so as to avoid the damage to the cup body 101 when the clamping assembly 5 moves upward.

[0105] When the placing table 42 moves to the position, the cup body driving element 22 is closed, and the clamping assembly 5 continues to move upward with the equipment platform 1 to the position where the distance between the inner walls of the clamping petals 52 is greater than the maximum outer diameter of the cup body 101, at this time, the clamping petals 52 do not interfere with the cup body 101, and the clamping assembly 5 can be withdrawn from the cup body 101 under the driving of the equipment platform 1, and when the clamping assembly 5 is withdrawn from the protection cavity 71 to the position with the equipment platform 1, the equipment platform 1 is closed.

[0106] Finally, the push rod 43 is driven downward by the pouring spout driving element 21 to the position where the limiting ring abuts against the side wall at the bottom of the limiting groove, at this time, the pouring spout forming block 3 moves inward synchronously with the push block 44 under the action of the dovetail 31 and the dovetail groove 441, so that the pouring spout forming block 3 is withdrawn from the cup body 101, and the cup body 101 is conveniently taken out from the protection table 7, at this time, the stamping work of the pouring spout on the cup body 101 is completed.

[0107] Finally, as shown in Figure 1 、 Figure 2 The cup body 101 is vacuumed through the vacuum hole 842, and at this time, the double-layer public cup is obtained. In addition to the above steps, the above steps can be added, subtracted, or sorted according to actual needs.
