Manufacturing method for double-layer fair mug

Abstract

A manufacturing method for a double-layer fair mug, the manufacturing method comprising: processing of an inner container (94), wherein a welding surface (93), which is recessed inwardly, is formed during the processing of the inner container (94); and processing of a mug body (101), wherein during the processing of the mug body (101), a pouring-spout forming device is used for stamping a pouring spout in a horizontal direction, and finally the mug body (101) is taken out to be subjected to a vacuuming operation so as to obtain a double-layer fair mug. The inwardly-recessed welding surface (93) is further processed at the mouth of the inner container (94), and is configured to be welded to a housing (84), and then the pouring spout is stamped in the horizontal direction by means of the pouring-spout forming device, such that a space is reserved when the mouth of a semi-finished mug (100) is pressed. Thus, the housing (84) and the inner container (94) are prevented from being completely attached after being pressed, and the pouring spout of the mug body (101) has a gap between the housing (84) and the inner container (94) of the mug body when compared with a pouring spout of a fair mug in the prior art, and therefore the liquid level in the mug is prevented from being in contact with the failure point of a heat preservation layer too early, thereby improving the heat preservation performance; and the mug body (101) is only subjected to an acting force in the horizontal direction, such that a situation wherein more burrs and scratches appear on an inner side wall of the pouring spout is avoided, and therefore the finished product quality and the production efficiency are improved.

Description

A method for manufacturing a double-layer fairness cup Technical Field

[0001] The invention relates to a method for manufacturing a cup, in particular to a method for manufacturing a double-layer fairness cup. Background Art

[0002] A fairness cup, also known as a teacup, is a vessel used to hold beverages such as water and tea. Traditional metal thermal containers have a pouring spout stamped directly into the container. However, fairness cups are relatively small, and the area below the spout where the inner liner and outer shell meet accounts for a significant portion of the cup's overall size. This transfers the temperature of the beverage directly through the inner liner to the outer shell, where it dissipates outward. This causes the liquid to cool too quickly, reducing the cup's insulation performance. Technical issues

[0003] The pouring spout on a fairness cup is often formed by die stamping. During production, the semi-finished cup body is clamped by a clamping device, and then a downward pressing mold is pressed in from the cup mouth to form the pouring spout. At this time, the cup wall is not only subjected to downward pressure, but also to horizontal impact force, which makes the inner wall of the pouring spout prone to more burrs and scratches. It needs to be polished before entering the later processing, which affects the production efficiency and quality of the fairness cup. Therefore, it is necessary to improve this. Technical Solutions

[0004] The present invention addresses the defects in the prior art such as the excessive contact area between the outer shell and the inner liner causing the vacuum layer to fail, resulting in a decrease in the thermal insulation performance of the fairness cup, and the use of a downward pressing mold to punch the pouring spout in the vertical direction causing wire drawing on the inner wall of the cup body, thereby reducing the production efficiency and quality of the finished product of the fairness cup. A new double-layer fairness cup manufacturing method is provided.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] A method for manufacturing a double-layer fairness cup, comprising:

[0007] Shell processing includes the following steps:

[0008] A1. Take wafer one and wafer one and perform stamping in steps to obtain a semi-finished shell product one;

[0009] A2. Perform a cutting operation on the semi-finished shell product 1 to obtain the semi-finished shell product 2;

[0010] A3, shaping, cutting, and flattening the semi-finished shell product 2 to obtain the semi-finished shell product 3;

[0011] A4. Punch and drill the bottom of the semi-finished shell part 3 to obtain a shell with grooves and vacuum holes on the bottom.

[0012] Liner processing includes the following steps:

[0013] B1. Take the second disc and perform stamping in steps to obtain the semi-finished inner liner product 1;

[0014] B2. Performing a whole-mouth operation on the semi-finished inner liner product 1 to obtain a semi-finished inner liner product 2, wherein the inner liner product 2 has a welding table surface that is concave inward along the diameter direction at the mouth;

[0015] B3, cutting and flattening the inner liner semi-finished product 2 to obtain the inner liner;

[0016] Cup body processing includes the following steps:

[0017] C1. Fitting the outer shell and the inner liner, and welding the upper end of the inner liner to the upper end of the outer shell to obtain a semi-finished cup body with a heat insulation layer;

[0018] C2. Polish the mouth of the semi-finished cup body, and then use a spout forming device to press the spout operation on the semi-finished cup body to obtain the cup body. The spout forming device includes a movably arranged equipment platform, a driving component, a spout forming block, an adjusting component, a clamping component and a supporting component. The clamping component is movably arranged on the equipment platform, and a shaping groove is also provided on the clamping component. The driving component is passed through the supporting component, and the adjusting component is arranged on the driving component and passes through the supporting component. The spout forming block is slidably arranged on the adjusting component, and the driving component drives the adjusting component to slide back and forth in the vertical direction. The spout forming block moves synchronously with the adjusting component in the horizontal direction and slides towards or away from the shaping groove. The steps of the spout pressing operation are:

[0019] D1. Start the driving assembly to move the adjustment assembly upwards into position, then take the semi-finished cup body and place it on the adjustment assembly;

[0020] D2. Then start the equipment platform to drive the clamping assembly to move towards the adjustment assembly. The clamping assembly clamps the outside of the cup body semi-finished product and pushes the adjustment assembly and the cup body semi-finished product downward into place.

[0021] D3. Then, the driving assembly is used to independently push the pouring spout forming block to slide horizontally toward the shaping groove and into position. At this time, the pouring spout is punched out on the semi-finished cup body to obtain the cup body;

[0022] D4. The clamping assembly is then driven upward by the equipment platform, and the driving assembly drives the adjusting assembly, the cup body and the equipment platform to move upward synchronously. When the adjusting assembly and the cup body are moved into place, the driving assembly stops working, and the equipment platform continues to move upward until the clamping assembly is separated from the cup body. At this time, the equipment platform stops driving the clamping assembly upward, and the cup body is taken out and vacuumed to obtain a double-layer fairness cup.

[0023] Preferably, in the above-mentioned method for manufacturing a double-layer fairness cup, the difference between the diameter of the welding table and the diameter of the second inner liner semi-finished product is in the range of 0.5 mm to 1.5 mm.

[0024] Preferably, in the above-mentioned method for manufacturing a double-layer fairness cup, before performing the cutting operation in step B3, the height difference between the upper end of the welding table and the second upper end of the semi-finished inner liner is in the range of 7.7 mm to 8.5 mm.

[0025] Preferably, in the above-mentioned method for manufacturing a double-layered fairness cup, the shaping operation in step A3 includes:

[0026] A31. Use a tendon die to stamp and expand the second semi-finished shell to form a tapered structure with a smaller top and a larger bottom. The difference between the maximum outer diameter of the second semi-finished shell at the bottom and the minimum outer diameter of the second semi-finished shell at the top is in the range of 14.6 mm to 15.4 mm.

[0027] A32. Then, a water expansion operation is performed to stretch the semi-finished shell product 2 so that a platform protruding toward the inside of the shell is formed at the bottom of the semi-finished shell product 2.

[0028] Preferably, in the above-mentioned method for manufacturing a double-layer fairness cup, a plurality of grooves are provided, the grooves are recessed toward the inside of the shell, the grooves are distributed at the bottom of the shell along the diameter direction of the shell, the grooves have different radii, the groove with the largest radius is distributed at the center of the bottom of the shell, and the remaining grooves are distributed on both sides of the groove with the largest radius in descending order of radius; the vacuum hole and the groove with the largest radius are coaxially arranged with the shell.

[0029] On the one hand, when making the pouring spout, the adjusting component drives the pouring spout forming block to slide horizontally toward the forming groove, so that the pouring spout of the cup body is only subjected to horizontal forces during the forming process, avoiding the appearance of burrs and scratches on the inner wall of the pouring spout, and improving the finished product quality of the cup body pouring spout and the production efficiency of the fairness cup.

[0030] On the other hand, the present invention adopts a method of further processing the mouth of the inner liner to process an inwardly recessed welding table for welding to the outer shell, and then horizontally moves the pouring spout forming block to make the pouring spout on the semi-finished cup body. It can not only reserve space when the mouth of the semi-finished cup body is extruded to avoid the outer shell and the inner liner from being completely fitted after extrusion, but also make the pouring spout on the formed cup body have a gap between the outer shell and the inner liner relative to the pouring spout of the existing fairness cup, thereby reducing the contact area between the outer shell and the inner liner at the lower end of the pouring spout, so that the failure point of the insulation layer formed by the contact between the outer shell and the inner liner is located higher than the liquid level in the cup, avoiding the liquid level in the cup from contacting the failure point of the insulation layer too early, so that the product has better insulation performance.

[0031] The grooves enhance the structural strength of the bottom of the semi-finished cup body, preventing the semi-finished cup body from deforming when the equipment platform and the clamping assembly are fixed to the outside of the semi-finished cup body, further improving the production efficiency and quality of the fairness cup. The vacuum operation is performed through the vacuum holes, creating a vacuum state between the outer shell and the inner liner, thereby blocking the conduction of temperature and further improving the thermal insulation performance of the fairness cup.

[0032] The supporting component limits the moving direction of the driving component, thereby ensuring the accuracy of the adjustment component when driving the pouring spout forming block to move.

[0033] Preferably, the above-mentioned method for manufacturing a double-layer fairness cup, the adjustment component includes an adjusting column and a placing table, the placing table is arranged on the adjusting column, a horizontal slide is provided on the placing table, and the pouring spout forming block is slidably arranged in the horizontal slide; a push rod is slidably provided in the adjusting column, the top of the push rod is provided with a push block passing through the top of the placing table, the lower end of the push rod is provided on the driving component, and the driving component drives the push rod and the push block to slide back and forth in the vertical direction; the push block is provided with a push inclined surface facing the horizontal slide, the top of the push inclined surface is inclined away from the horizontal slide, and a dovetail groove extending along the height direction of the push block is provided on the push inclined surface, and the pouring spout forming block is provided with a dovetail tenon engaged with the dovetail groove, and the push block drives the pouring spout forming block to slide synchronously in the horizontal direction through the dovetail groove and the dovetail tenon.

[0034] The use of a push-in bevel, dovetail groove, and dovetail tenon to achieve the sliding motion of the spout forming block driven by the push-in block not only improves the tightness of the connection between the push-in block and the spout forming block, but also enhances the consistency and smoothness of their movement. The provision of a horizontal slideway limits the sliding direction of the spout forming block, preventing the spout forming block from offsetting from the sizing groove during the spout stamping process, further improving the quality of the finished product.

[0035] Preferably, in the above-mentioned method for manufacturing a double-layer fairness cup, the adjustment component also includes a positioning block arranged on the placement table, the positioning block is provided with a movable groove, the pouring spout forming block and the push block are slidably arranged in the movable groove; the outer wall of the positioning block is circumferentially provided with an outwardly protruding fitting surface, the fitting surface is fitted with the inner surface of the welding table, and the clamping component is clamped on the outside of the positioning block.

[0036] On the one hand, the movable groove is used to limit the upper limit and direction of the sliding of the push block and the pouring spout forming block, further improving the consistency of the synchronous movement of the push block and the pouring spout forming block, ensuring the subsequent production of the fairness cup; on the other hand, when the cup body semi-finished product is covered on the outside of the positioning block, the pre-positioning of the cup body semi-finished product is achieved, which facilitates the precise clamping of the clamping assembly on the outside of the cup body semi-finished product. Through the interaction between the positioning block and the clamping assembly, the cup body semi-finished product is not prone to deformation and bending on the surface except for the pouring spout part during stamping; the fitting surface makes the connection between the inner liner and the positioning block tight, further ensuring that the inner liner and the outer shell cannot be completely fitted after extrusion, further enhancing the thermal insulation effect of the fairness cup.

[0038] The pouring spout drive realizes the independent drive of the push rod, reduces the interference received by the push rod during sliding, and realizes the sliding of the overall position of the adjustment component through the cup body drive, which not only makes it convenient for users to remove the cup body from the placement table or place the semi-finished cup body on the placement table, but also can cooperate with the clamping component to move, thereby preventing the clamping component from colliding with the cup body or cup body semi-finished product placed on the adjustment component.

[0039] Preferably, in the above-mentioned method for manufacturing a double-layer fairness cup, the clamping assembly includes at least two clamping petals, the clamping petals are circumferentially arranged and move toward or away from each other, and the shaping groove is arranged on the inner side wall of one of the clamping petals; it also includes a guide rod corresponding to the clamping petals one by one, one end of the guide rod is arranged on the respectively corresponding clamping petal, and the other end of the guide rod passes through the equipment platform, and an elastic reset part is sleeved on the guide rod, and the two ends of the elastic reset part are respectively abutted against the guide rod and the equipment platform, and the elastic reset part pushes the clamping petals to move away from each other.

[0040] By controlling the spacing between the clamping petals, it is convenient to clamp the cup body semi-finished product, and it is also convenient to detach the clamping assembly from the outside of the formed cup body; the guide rod plays a guiding role when the clamping petals slide, which improves the smoothness of the clamping petals when moving towards or away from each other; the setting of the elastic reset part realizes the automatic reset of the clamping petals, which facilitates the smooth progress of subsequent steps. At the same time, the elastic reset part increases the total height difference when the clamping assembly clamps the cup body semi-finished product, so that the clamping assembly and the equipment platform can be suitable for cup body semi-finished products of different heights, thereby ensuring the consistency of the cup body mouth and improving the accuracy of the adjustment assembly when punching the pouring spout.

[0041] Preferably, in the above-mentioned method for manufacturing a double-layer fairness cup, a protective platform is provided on the upper surface of the support assembly, a protective cavity is opened on the protective platform, and the upper end of the adjustment column is inserted into the protective cavity; a clamping guide surface is provided on the inner wall of the protective platform, the top end of the clamping guide surface is inclined toward the outer wall of the protective platform, and the clamping guide surface is in contact with the outer wall of the clamping petal.

[0042] When the pouring spout of the cup body semi-finished product is stamped, the protective platform and the protective cavity are used to protect the cup body semi-finished product and the clamping assembly; the clamping guide surface can support and guide the end of the clamping petal, further improving the smoothness of the clamping petals when moving towards each other, and realizing the function of the clamping petals to accurately and smoothly clamp the outside of the cup body semi-finished product.

[0095] Preferably, a protective platform 7 is provided on the upper surface of the support assembly 6, and a protective cavity 71 is opened on the protective platform 7, and the upper end of the adjustment column 41 is inserted into the protective cavity 71; a clamping guide surface 72 is provided on the inner wall of the protective platform 7, and the top end of the clamping guide surface 72 is inclined toward the outer wall of the protective platform 7, and the clamping guide surface 72 is in contact with the outer wall of the clamping petal 52.

[0096] Preferably, a first step 11 is provided on the equipment platform 1, and a strip block 521 is provided on the clamping petal 52, and the clamping petal 52 is slidably set on the first step 11 through the strip block 521; a protrusion 12 is provided on the lower surface of the equipment platform 1, and a cup body fixing groove 13 is provided on the lower surface of the protrusion 12, and a placement notch 522 is provided on the inner side wall of the clamping petal 52, and the protrusion 12 is located between the placement notches 522; the clamping assembly 5 forms a clamping state and a reset state. In the clamping state, adjacent clamping petals 52 are abutted against each other, and the protrusion 12 is inserted into the placement notch 522. The cup body fixing groove 13 is located between the clamping petals 52 and contacts the end of the cup body semi-finished product 100, and the strip block 521 moves inward along the first step 11; in the reset state, adjacent clamping petals 52 are separated, the protrusion 12 withdraws from the placement notch 522, and the strip block 521 moves outward along the first step 11.

[0097] More specifically, when punching the pouring spout of a fairness cup, as shown in FIG6-16 , four steps may be performed.

[0098] When performing step D1, as shown in Figures 6, 7, and 11, start the cup body drive 22 to push the adjustment column 41 upward into place, and then put the cup body semi-finished product 100 on the positioning block 45 and make the welding table 93 and the fitting surface 452 fit together.

[0099] When performing step D2, as shown in Figures 11-13, the equipment platform 1 is started to move the clamping assembly 5 toward the positioning block 45. When the lower end of the clamping flap 52 contacts the clamping guide surface 72, the clamping flap 52 moves toward each other under the action of the clamping guide surface 72 and is retracted on the outside of the cup body semi-finished product 100, and the elastic reset part 54 is gradually compressed; as the clamping flap 52 gradually moves downward, the lower end of the clamping flap 52 is placed on the top of the placement table 42 and pushes the adjustment assembly 4 as a whole to move downward until the lower surface of the placement table 42 is in contact with the inner wall of the bottom of the protective cavity 71. At this time, the clamping flap 52 is clamped on the outside of the cup body semi-finished product 100, and the top of the cup body semi-finished product 100 is inserted into the cup body fixing groove 13. The elastic reset part 54 continues to be compressed. At this time, the clamping assembly 5 completes the fixation of the cup body semi-finished product 100.

[0100] In this embodiment of the present application, the elastic return member 54 is made of tendon material, which allows it to cooperate with the clamping guide surface 72 to elastically adjust the clamping petal 52. This increases the total height difference of the cup body when the clamping assembly 5 clamps the semi-finished cup body 100, ensures the consistency of the mouth of the semi-finished cup body 100, and improves the accuracy of the adjustment assembly 4 when punching the pouring spout. At the same time, the groove 841 enhances the structural strength of the bottom of the semi-finished cup body 100, so that the semi-finished cup body 100 is not easily deformed when the equipment platform 1 and the clamping assembly 5 are clamped on the outside of the semi-finished cup body 100.

[0101] When performing step D3, as shown in Figures 8-10 and 15, the pouring spout driving member 21 is started to move the push rod 43 upward. As the push rod 43 gradually moves upward, the pouring spout forming block 3 moves outward under the push of the push slope 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 to form a pouring spout.

[0102] During stamping, the inner wall of the inner liner 94 is only subjected to lateral pressure, which not only avoids the appearance of many burrs and scratches on the inner wall of the pouring spout, but also avoids the outer shell 84 and the inner liner 94 from being completely fitted together after being squeezed. At the same time, the pouring spout on the cup body 101 has a gap between the outer shell 84 and the inner liner 94 compared to the pouring spout of the existing fairness cup, thereby reducing the contact area between the outer shell 84 and the inner liner 94, and making the failure point of the insulation layer formed by the contact between the outer shell 84 and the inner liner 94 located at a higher point of the liquid level inside the cup body 101, thereby avoiding the internal liquid level of the cup body 101 from contacting the failure point of the insulation layer too early, so that the product has better insulation performance.

[0103] When performing step D4, as shown in Figures 7-13 and 16, when the pouring spout is stamped, the equipment platform 1 is first moved upward, and the cup body driving member 22 is used to control the adjustment component 4 and the equipment platform 1 to move upward synchronously. The clamping petals 52 are reset in the direction away from each other under the elastic force of the elastic reset member 54 and gradually separate from the clamping guide surface 72 and the outer surface of the cup body 101, thereby avoiding damage to the cup body 101 when the clamping component 5 moves upward.

[0104] When the placement table 42 moves into position, the cup body drive 22 is closed, and the equipment platform 1 drives the clamping assembly 5 to continue to move upward until 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 and the cup body 101 do not interfere with each other, and the clamping assembly 5 can be withdrawn from the cup body 101 under the drive of the equipment platform 1. When the clamping assembly 5 withdraws from the protective cavity 71 into position with the equipment platform 1, the equipment platform 1 is closed.

[0105] Finally, the pouring spout driving member 21 is used to drive the push rod 43 to move downward until the limiting ring and the bottom side wall of the limiting groove are butted against each other. At this time, the pouring spout forming block 3 moves inward synchronously with the push block 44 under the action of the dovetail tenon 31 and the dovetail groove 441, so that the pouring spout forming block 3 is withdrawn from the cup body 101, making it convenient to remove the cup body 101 from the protective platform 7. At this time, the stamping work of the pouring spout on the cup body 101 is completed.

[0106] Finally, as shown in Figures 1 and 2, the cup body 101 is vacuumed through the vacuum hole 842, and a double-layered fairness cup is obtained. In addition to the above steps, the above steps can be increased or decreased in order according to actual needs. Example 2

[0107] Preferably, the difference between the diameter of the welding table 93 and the diameter of the second inner liner semi-finished product 92 is in the range of 1.5 mm.

[0108] Preferably, before the cutting operation in step B3 is performed, the height difference between the upper end of the welding table 93 and the upper end of the second inner liner semi-finished product 92 is in the range of 8.5 mm.
