Description

Technical Field

[0001] The present invention relates to a method for manufacturing a cup, and particularly to a method for manufacturing a double single-mouth cup.

Background Art

[0002] A single-mouth cup, also called a drinking cup, is a utensil for containing drinks such as water and tea. In conventional metal thermal containers, a water outlet is processed directly on the container by pressing. However, since the volume of the single-mouth cup itself is small the portion where the cup liner at the lower end of the water outlet and the outer shell stick together occupies a large proportion of the whole body, and the temperature of the drink in the cup is directly transmitted from the cup liner to the outer shell and dissipates to the outside Therefore, the liquid in the cup cools too fast, and the heat preservation performance of the cup decreases and deteriorates.

[0003] The water outlet in the single-mouth cup is usually formed by die pressing. During production, the semi-finished cup body is clamped through a clamping device, and then the downward pressing die is pushed from the direction of the cup mouth to form the water outlet. At this time, the wall of the cup not only receives downward pressure, but also receives a horizontal impact force, which easily causes many burrs and scratches on the inner wall of the water outlet. After being polished and then entering the subsequent processes, it affects the productivity and quality of the single-mouth cup, so it is necessary to improve this .

Summary of the Invention

[0004] In view of the deterioration of the vacuum layer due to the too large contact area between the outer shell and the cup liner existing in the prior art, while the heat preservation performance of the single-mouth cup decreases, by using a downward pressing die to press vertically it leads to situations such as wire drawing on the inner wall of the single-mouth cup, resulting in a decrease in the production efficiency and quality of the single-mouth cup To solve problems such as these, a new method for manufacturing a double-sided port is provided.

The drive unit is movably mounted on the foam and is further provided with foam grooves. The adjustment unit is attached to the drive unit. The water outlet molding block is provided on the adjustment unit, and is inserted through the support unit. The driving unit drives the adjusting unit to slide back and forth based on the vertical direction. The water outlet forming block moves synchronously with the adjustment unit horizontally and closes to the foam groove. The water outlet pressing operation steps are as follows: is.

[0019] D1. First, start the drive unit to move the adjustment unit to the designated position, then insert the cup holder. Take the body semi-finished product and place it on the adjustment unit.

[0020] D2, Next, start the device platform and move the clamp unit closer to the adjustment unit. The clamp unit moves in the direction of the clamping force, clamping the outside of the cup body semi-finished product and adjusting it. Push the unit and the semi-finished cup body to move them down to the designated position.

[0021] D3. Then, through the drive unit, the water outlet forming block is horizontally moved alone in a direction approaching the forming groove. At this time, the water outlet is pressed onto the cup body semi-finished product to obtain the cup body.

[0022] D4. Then, through the device platform, the clamp unit is moved upward, and the drive unit moves the adjustment unit and the cup body in synchronization with the device platform. After the adjustment unit and the cup body move to a predetermined position, the operation of the drive unit stops, and the device platform continues to move upward, separating the clamp unit from the cup body. At this time, the device platform stops moving the clamp unit upward, and the cup body is taken out and degassed to obtain a double-sided single opening, which is a manufacturing method of the double-sided single opening.

[0023] Preferably, in the manufacturing method of the double-sided single opening, the difference between the diameter of the welding table and the diameter of the cup liner semi-finished product II ranges from 0.5 mm to 1.5 mm.

[0025] Preferably, in the manufacturing method of the double-sided single opening, the shaping operation in step A3 includes the following.

[0026] A31. Using the TPR type, the outer shell semi-finished product II is pressed and expanded, and the outer shell semi-finished product II is smaller at the top and larger at the bottom. ​​​​​​​​​​It is formed in a large tapered shape. The difference between the maximum outer diameter at the lower end of the outer shell semi-finished product 2 and the minimum outer diameter at the upper end of the outer shell semi-finished product 2 is in the range of 14.6 mm to 15.4 mm.

[0027] A32. Next, perform a hydroforming operation to stretch the outer shell semi-finished product 2 so that the bottom of the outer shell semi-finished product 2 becomes a platform arm that protrudes into the outer shell.

[0028] Preferably, in the manufacturing method of the double single opening, a plurality of the groove portions are provided. The groove portions are recessed inside the outer shell and are arranged at the bottom along the diameter direction of the outer shell. The radius of the groove portion is 1 or less, and the groove portion with the largest radius is arranged at the center of the bottom of the outer shell. The remaining groove portions are arranged on both sides of the groove portion with the largest radius in the order of decreasing radius. The vacuum hole and the groove portion with the largest radius are provided coaxially with the outer shell.

[0029] On the other hand, when creating the water outlet, since the adjustment unit slides and moves the water outlet forming block in the direction approaching the form groove in the horizontal direction, the water outlet of the cup body only receives a horizontal directional force during the forming process. Therefore, it is possible to avoid a large number of burrs and scratches on the inner wall of the water outlet, and improve the quality of the finished product of the water outlet of the cup body and the production efficiency of the single opening.

In this way, not only can the pace be ensured when pressing the mouth portion of the cup body semi-finished product, but also the outer shell and the cup liner after pressing can be completely adhered to each other. ​​can be avoided. At the same time, the water outlet in the formed cup body has a gap between its outer shell and the cup liner compared with the conventional single-sided water outlet mouth, reducing the contact area between the outer shell at the lower end of the water outlet and the cup liner, and positioning the failure point of the heat preservation layer formed by the contact between the outer shell and the cup liner at a higher position of the liquid level in the cup to avoid contacting the too-early heat preservation layer failure point of the liquid surface in the cup, so that the product has better heat preservation performance

[0031] Through the groove, the structural strength of the bottom of the cup body semi-finished product is enhanced. Therefore, when fixing the device platform and the clamp unit outside the cup body semi-finished product, the cup body semi-finished product is not easily deformed, improving the production efficiency and quality of the single-sided production. Through the exhaust operation of the vacuum hole, the outer shell and the cup liner are in a vacuum state, blocking heat conduction and further enhancing the heat preservation performance

[0032] The support unit can limit the moving direction of the driving unit, so as to ensure the accuracy when the adjustment unit moves the water outlet forming block

The inner wall of the protection platform 7 is provided with a clamp guide surface 72, and the tip of the clamp guide surface 72 is inclined in a direction approaching the outer wall of the protection platform 7, and the clamp guide surface 72 is offset with the clamp valve 52 .

[0097] Preferably, a first step (11) is provided on the first step of the device platform staircase, and the rectangular block step 521 is provided on the 52nd step of the clamp valve staircase. The 5 2nd step of the clamp valve is slidably arranged on the 11th step of the first step through the rectangular block step 521 . A protruding block step 12 is provided on the bottom surface of the first step of the device platform staircase. A cup body fixing groove step 13 is provided on the bottom surface of the protruding block step 12. The inner wall of the 52nd step of the clamp valve is provided with a placement gap step 522. The protruding b lock step 12 is located between the placement gap steps 522. The clamp unit step 5 is formed in a clamped state and a reset state. In the clamped state , adjacent 52nd steps of the clamp valve are offset, the protruding block step 12 is placed inserted into the placement gap step 522, and the cup body fixing groove step 13 is located between the 52nd steps of the clamp valve and contacts the end of the cup body semi-finished product step 100. The rectangular block step 521 moves inward along the 11th step of the first step. The In the reset state, adjacent 52nd steps of the clamp valve are separated, the protruding block step 12 is withdrawn from the placement gap step 522, and the rectangular block step 521 is the first Move outwards along the 1st stair 11st stair.

[0098] More specifically, the single-mouth water outlet pressing process involves four steps, as shown in Figures 6 to 16. This goes through.

[0099] When step D1 is performed, the cup body driving unit 22 is started as shown in FIGS. After the adjustment column 41 is pushed up to a predetermined position, the cup body semi-finished product 100 is placed on the positioning block 4. 5, and the welding table 93 and the contact surface 452 are bonded together.

[0100] When performing step D2, as shown in FIG. 11 to FIG. 13, the device platform 1 is started up, The clamp unit 5 is moved in a direction approaching the positioning block 45, and the lower end of the clamp valve 52 is When the clamp valves 52 contact the clamp guide surfaces 72, the clamp valves 52 are held together by the clamp guide surfaces 72. The elastic reset unit 5 moves in the approaching direction to pull the semi-finished cup body 100 to the outside. As the clamp valve 52 moves gradually downward, the The lower end is disposed on the top of the placement table 42, and the entire adjustment unit 4 is disposed between the lower part of the placement table 42 and the protective cavity 71. At this time, the clamp valve 52 moves downward so as to come into close contact with the bottom inner wall of the cup body. The top of the semi-finished cup body 100 is inserted into the fixed tank 13 of the cup body. The elastic reset unit 54 is then compressed, and the cup body semi-finished product 100 The fixing of the clamp unit 5 to the substrate 1 is then completed.

[0101] In the embodiment of the present application, the elastic reset unit 54 is made of TPR material and the clamp guide surface 72 The clamp valve 52 can be elastically adjusted to fit the cup body half. When clamping the product 100, the difference in the overall height of the cup is increased, ensuring the consistency of the mouth part of the semi-finished product 100 of the cup body. The adjusting unit 4 improves the accuracy when pressing the water outlet. Also, the aforementioned groove 841 strengthens the structural strength of the bottom of the semi-finished product 100 of the cup body. Therefore, when the device platform form 1 and the clamping unit 5 clamp the outside of the semi-finished product 100 of the cup body, the semi-finished product 100 of the cup body is less likely to be deformed.

[0102] When performing step D3, as shown in FIGS. 8 to 10 and FIG. 15, the water outlet driving unit 21 is activated to move the stop lever 43 upward. As the stop lever 43 gradually moves upward and is pushed by the stop inclined surface 440, the water outlet forming block 3 moves outward. At this time, the side wall of the semi-finished product 100 of the cup body is deformed due to the pressing between the water outlet forming block 3 and the foam groove 51, and a water outlet is formed.

[0103] When pressing, the inner wall of the cup liner 94 only receives lateral pressure, which not only prevents a large number of burrs and scratches from occurring on the inner wall of the water outlet, but also prevents the outer shell 84 and the cup liner 94 from being completely adhered after pressing. Thus, compared with the conventional single opening, the water outlet in the cup body 10 1 has a gap between the outer shell 84 and the cup liner 94, so the contact area between the outer shell 84 and the cup liner 94 is reduced, and the heat preservation layer failure point formed by the contact between the outer shell 84 and the cup liner 94 is located at a position higher than the internal liquid level of the cup body 101. Therefore, it is possible to avoid the internal liquid level of the cup body 101 contacting the heat preservation layer failure point too early and improve the heat preservation performance.

[0104] When performing step D4, as shown in FIGS. 7 to 13 and FIG. 16, after the water outlet press is completed, first, move the device platform 1 upward, and control the adjustment unit 4 through the cup body drive unit 22 so that it moves upward in synchronization with the device platform 1. The clamp valve 52 is reset in a direction away from each other by the elastic force of the elastic reset member 54, and gradually separates from the clamp guide surface 72 and the outer surface of the cup body 101, so as to avoid damaging the cup body 101 when the clamp unit 5 moves upward.

[0105] After the placement table 42 moves to a predetermined position, the cup body drive unit 22 closes, and is pulled by the device platform 1, and the clamp unit 5 continues to move upward between the inner walls of the clamp valve 52, and the sensing distance is larger than the maximum outer diameter of the cup body 101. At this time, the clamp unit 5 and the clamp valve 52 and the cup body 101 do not interfere with each other, and can be pulled out from the cup body 101 by being pulled by the device platform 1. When the clamp unit 5 exits from the protection cavity 71 to a predetermined position together with the device platform 1, the device platform 1 closes. Finally, the water outlet drive unit 21 moves the stop lever 43 downward to the stopper stopping, and cancels with the bottom side wall of the stopper groove. At this time, the water outlet forming block 3

[0106] moves inward synchronously with the stop block 44 through the joint 31 and the joint groove 441, so that the water outlet forming block 3 exits from the stopper 101, and the cup body 101 can be easily taken out from the protection base 7. At this time, the press work of the water outlet on the cup body 101 is completed .​​​

[0107] Finally, as shown in FIGS. 1 and 2, the cup body 101 is evacuated to a vacuum through the vacuum holes 842 When this is done, a double-sided product is obtained at this time. Except for the above steps, according to actual needs The order can be changed or rearranged.
