Description

Technical Field

[0001] The present invention belongs to the technical field of automatic labeling equipment, and particularly relates to an automatic decaling equipment and method for thermos cups.

Background Art

[0002] Thermal transfer printing is to first print a selected pattern on a transfer paper through a printer, then stick the transfer paper on the surface of an item to be transferred (such as porcelain, stainless steel, etc.), and place the item with the transfer paper on it in a high-temperature environment of about 200 °C for several minutes. The special ink on the thermal transfer paper then sublimates and adheres to the surface of the item with a resin coating that is in close contact with it, completing the thermal transfer process of a selected image from the transfer paper to the item surface. The image after thermal transfer printing is colorful, and the pattern is firmly combined with the item surface. The item after thermal transfer printing becomes a highly personalized fashion item.

[0003] To improve the aesthetics of thermos cups, most thermos cups will stick a layer of the above-mentioned transfer paper on their outer peripheral surface during the production process, which is called "flower paper" in the industry. To achieve the automatic pasting of the above flower paper, the prior art patent CN111746101A discloses a rotary body outer cylindrical surface thermal transfer production line and an automatic thermal transfer method, which sets up a transfer paper clamping device. The transfer paper is placed on an elastic fastening leather, and then the elastic fastening leather carrying the transfer paper is wrapped around the outer peripheral surface of the rotary body. Then, the elastic fastening leather and the rotary body enter the oven together for baking to complete the pasting of the transfer paper on the rotary body. This equipment has some disadvantages:

[0004] (1) It is necessary to set up more elastic fastening leathers for recycling, and it is also necessary to perform operations such as wrapping the elastic fastening leather, installing the buckle, and disassembling the elastic fastening leather and the buckle. The operations are cumbersome, the material consumption is large, the cost is high, and the efficiency is low;

[0005] (2) When the elastic fastening leather wraps the rotary body, it cannot achieve a seamless circumferential wrap, and there is a gap at the joint of the elastic fastening leather, which cannot meet the requirement of pasting the transfer paper for more than 360 degrees;

[0006] (3) The equipment occupies a large space.

[0007] Therefore, it is necessary to provide a new automatic decaling equipment and method for thermos cups to solve the above technical problems.

Summary of the Invention

[0008] One of the main purposes of the present invention is to provide an automatic decaling equipment for thermos cups, which occupies a small space, has simple flower paper pasting actions, high efficiency, low equipment manufacturing cost, and good decaling quality.

[0009] The present invention achieves the above object through the following technical solutions: An automatic decal device for a heat-insulated cup, which comprises:

[0010] A rotary clamping mechanism, including a first support plate, a first rotary support and a second rotary support axially arranged opposite to each other on the first support plate, and a first driving member fixed on the first support plate and driving the second rotary support to axially press the heat-insulated cup;

[0011] A heating and rolling mechanism, including a second driving member, a fourth support seat driven by the second driving member to move up and down, a decal rolling wheel rotatably arranged on the fourth support seat, and a heater arranged on the fourth support seat and heating the decal rolling wheel;

[0012] A decal supporting and feeding mechanism, including a decal supporting platform located beside the rotary clamping mechanism;

[0013] A third driving member, driving the decal rolling wheel, or the first rotary support, or the second rotary support to rotate.

[0014] Further, the first rotary support includes a first support seat, a first rotating shaft rotatably arranged on the first support seat, and an inner support member fixed on the first rotating shaft and extending into the interior of the heat-insulated cup from the cup mouth end of the heat-insulated cup; A limiting groove imitating the bottom end of the heat-insulated cup is formed on the surface of the second rotary support facing the first rotary support.

[0015] Further, the inner support member has a conical structure, and the circumferential diameter of the end far from the first support seat is small, and the circumferential diameter of the end close to the first support seat is large.

[0016] Further, a support roller assembly for supporting the heat-insulated cup is arranged at the position between the first rotary support and the second rotary support on the first support plate; The support roller assembly is installed on the first support plate with adjustable vertical height and axial position.

[0017] Further, a temperature sensor for monitoring the temperature of the heat-insulated cup is arranged on the first support plate.

[0018] Further, the rotary clamping mechanism further includes a first hinge seat and a support vertical plate; One end of the first support plate is rotatably arranged on the first hinge seat, and the other end is fixedly arranged on the support vertical plate with adjustable vertical position.

[0019] Further, the heating and rolling mechanism further includes a third support plate driven by the second driving member to move up and down. A second hinge seat is provided on the third support plate. One end of the fourth support seat is rotatably provided on the second hinge seat, and the other end is hung on the third support plate through an angle adjusting screw. A spring for pressing the fourth support seat downward is provided on the angle adjusting screw.

[0020] Further, the flower paper supporting mechanism further includes a fourth driving member for driving the flower paper supporting platform to move up and down. A plurality of air suction holes for adsorbing the flower paper are provided on the surface of the flower paper supporting platform.

[0021] Further, it further includes a flower paper feeding mechanism for supplying flower paper and a flower paper handling mechanism for sucking the flower paper from the flower paper feeding mechanism and transporting it to the flower paper supporting platform.

[0022] Another object of the present invention is to provide a decal application method implemented based on the above-mentioned automatic decal application device for thermos cups, including the following steps:

[0023] S1. Place the thermos cup in a lying state on the rotary clamping mechanism. The first rotary support member extends into the interior of the thermos cup from the cup mouth end to fix the cup mouth end of the thermos cup, and the second rotary support member axially presses the thermos cup from the bottom end of the cup to fix the thermos cup.

[0024] S2. Place a piece of flower paper on the flower paper supporting platform. One end of the flower paper extends above the top of the outer peripheral surface of the thermos cup, and the air suction holes on the flower paper supporting platform are used to adsorb the flower paper.

[0025] S3. The flower paper rolling wheel descends to press one end of the flower paper tightly against the thermos cup. The third driving member drives the flower paper rolling wheel, the first rotary support member or the second rotary support member to rotate, and then drives the thermos cup to rotate, pasting the flower paper onto the outer peripheral surface of the thermos cup. At the same time, the heater heats the flower paper rolling wheel, and then transfers the heat to the thermos cup through the contact between the flower paper rolling wheel and the thermos cup to heat the thermos cup.

[0026] S4. After the temperature of the thermos cup reaches the set temperature, take out the thermos cup from the rotary clamping mechanism and then place it on the baking conveyor line for baking and curing.

[0027] Compared with the prior art, the beneficial effects of the automatic decal application device and method for thermos cups of the present invention are as follows:

[0028] (1) By setting up a rotating clamping mechanism, the inner support member extends into the thermos cup from the cup mouth end of the thermos cup, and the conical structure design of the inner support member is used to fix the white mouth end of the thermos cup. The imitation-shaped limiting groove on the second rotating support member axially presses the bottom end of the thermos cup to position the bottom end of the thermos cup, ensuring that the central axis of the thermos cup is collinear with the rotation axis of the rotating clamping mechanism, laying an important foundation for the precise pasting of the decorative paper;

[0029] (2) By setting up a heating and rolling mechanism above the rotating clamping mechanism, the heater heats the decorative paper rolling wheel, and then the decorative paper rolling wheel contacts the thermos cup to heat the thermos cup. At the same time, the decorative paper rolling wheel clamps and rotates with the thermos cup. First, one end of the decorative paper is pasted onto the thermos cup, and then the whole decorative paper is wound and wrapped around the outer peripheral surface of the thermos cup by the self-rotation of the thermos cup, realizing the pasting of the decorative paper. The whole pasting process is simple and does not require a complex pasting structure;

[0030] (3) A structure capable of adjusting the angle of the rotation axis is designed in the rotating clamping mechanism. One end of the first support plate is rotatably arranged on the first hinge seat, and the other end is fixedly arranged on a support vertical plate with adjustable up and down positions, thereby realizing the angle adjustment of the overall rotation axis of the rotating clamping mechanism to be applicable to thermos cups with gradually changing outer diameters axially, improving the versatility of the equipment;

[0031] (4) An adjustment structure capable of adjusting the rolling pressure of the decorative paper rolling wheel is designed in the heating and rolling mechanism. One end of the fourth support seat is rotatably arranged on the second hinge seat, and the other end is arranged on the third support plate with adjustable up and down positions, thereby realizing the angle adjustment of the central axis of the decorative paper rolling wheel. Cooperating with the spring pressing one end of the fourth support seat, the rolling pressure of the decorative paper rolling wheel is adjusted to be applicable to the pasting of decorative papers with various different rolling pressure requirements, improving the flexibility of the equipment;

[0032] (5) By setting up a decorative paper supporting mechanism, on the one hand, it supports the decorative paper so that the part of the decorative paper that has not been pasted onto the thermos cup can remain flat during pasting, thereby ensuring that there are no wrinkles or bubbles after the decorative paper is pasted onto the thermos cup, improving the pasting quality of the decorative paper. On the other hand, the decorative paper is at a height position flush with the tangent line of the thermos cup, enabling the decorative paper to be pasted more effectively and smoothly with the self-rotation of the thermos cup.

Specific implementation manner

[0047] Embodiment 1:

[0048] Please refer to Figures 1 - 8, this embodiment is an automatic decal device 100 for a thermos cup, which includes a rotary clamping mechanism 1 that holds the thermos cup 200 in a lying state and rotates it, a heating and rolling mechanism 2 located directly above the rotary clamping mechanism 1, a paper carrier mechanism 3 arranged beside the rotary clamping mechanism 1, a paper feeder mechanism 4 arranged beside the paper carrier mechanism 3, and a paper handling mechanism 5 that transports the paper from the paper feeder mechanism 4 to the paper carrier mechanism 3.

[0049] The rotary clamping mechanism 1 includes a first support plate 11, a first rotary support 12 and a second rotary support 13 axially opposite to each other on the first support plate 11, and a first driving member 14 fixed on the first support plate 11 and driving the second rotary support 13 to axially press the thermos cup 200. The first rotary support 12 includes a first support base 121, a first rotating shaft 122 rotatably arranged on the first support base 121, and an inner support member 123 fixed on the first rotating shaft 122 and internally supporting the thermos cup 200. The inner support member 123 has a conical structure, and the circumferential diameter of the end far from the first support base 121 is small, and the circumferential diameter of the end close to the first support base 121 is large, so that the inner support member 123 can smoothly extend into the thermos cup 200, and at the same time can also be compatible with the internal support of thermos cups of various different diameters. A limiting groove (not marked in the figure) is opened on the surface of the second rotary support 13 facing the first rotary support 12. When the second rotary support 13 presses the thermos cup 200, the bottom of the thermos cup 200 extends into the limiting groove, and the bottom of the limiting groove axially supports the bottom of the thermos cup to achieve axial pressing. The limiting groove is designed to be similar to the bottom of the thermos cup 200, and can keep the center of the bottom end of the thermos cup on the rotation axis of the rotary clamping mechanism 1 while axially pressing the thermos cup. The inner support member 123 extends into the thermos cup 200 from the cup mouth end of the thermos cup to fix the cup mouth end of the thermos cup, and the second rotary support 13 axially presses the thermos cup from the cup bottom end of the thermos cup to realize the fixed clamping of the surrounding cup.

[0050] A second support plate 15 is arranged at the movable end of the first driving member 14, a second support base 16 is arranged on the second support plate 15, and the second rotary support 13 is rotatably arranged on the second support base 16. A second rotating shaft 17 is rotatably arranged on the second support base 16, and the second rotary support 13 is fixedly installed on the second rotating shaft 17 by a quick-change structure, so as to realize the rotatable arrangement on the second support base 16. The quick-change installation structure of the second rotary support 13 can be conveniently replaced to be suitable for the end pressing and limiting of thermos cups of various different diameters.

[0051] To improve the support strength for the heat-insulated cup, a support roller assembly 18 for supporting the heat-insulated cup body is provided at a position on the first support plate 11 between the first rotary support member 12 and the second rotary support member 13. The support roller assembly 18 includes a third support seat 181 and a pair of rollers 182 arranged side by side on the third support seat 181 and located on both sides of the rotation axis of the rotary clamping mechanism 1. The third support seat 181 is installed on the first support plate 11 with its vertical height and axial position adjustable to be applicable to the bottom support of heat-insulated cups with various different diameters and different axial dimensions.

[0052] When pasting the decorative paper on the heat-insulated cup 200, the temperature of the heat-insulated cup 200 needs to reach the set requirement before the decorative paper can be completely pasted onto the heat-insulated cup. If the temperature of the heat-insulated cup 200 does not meet the standard, the pasted decorative paper is likely to wrinkle and warp. To solve this technical problem, in this embodiment, a temperature sensor 19 is provided on the first support plate 11 to align with the outer peripheral surface of the heat-insulated cup 200. The temperature of the heat-insulated cup 200 is monitored by the temperature sensor 19, and the heat-insulated cup 200 with the pasted decorative paper can be removed from the rotary clamping mechanism 1 only after the temperature of the heat-insulated cup 200 reaches the standard.

[0053] Some heat-insulated cups 200 are straight cylindrical, and there is no difference in the outer peripheral diameter in the axial direction. However, for some heat-insulated cups 200, the outer peripheral diameter is gradually changed in the axial direction. For example, the structure has a small bottom diameter and a large cup mouth diameter. After this type of heat-insulated cup is fixed to the rotary clamping mechanism 1, the top axial of the outer peripheral surface is an inclined plane, which is not conducive to the effective pasting of the decorative paper and is likely to cause incomplete pressing of the decorative paper and the appearance of air bubbles. To solve this technical problem, in this embodiment, one end of the first support plate 11 is rotatably arranged on the first hinge seat 110, and the other end is fixedly arranged on a support vertical plate 111 with its vertical position adjustable. An arc-shaped sliding groove 1111 is provided on the support vertical plate 111, and a locking screw (not marked in the figure) passing through the arc-shaped sliding groove 1111 is provided on the first support plate 11. The first support plate 11 is rotatably arranged on the first hinge seat 110, so that the first support plate 11 can adjust the angle of its support surface, and further realize the pitching angle of the rotation axis of the entire rotary clamping mechanism 1 to be applicable to heat-insulated cups with a gradually changed outer peripheral diameter in the axial direction. After this type of heat-insulated cup is fixed to the rotary clamping mechanism 1, the top axial of the outer peripheral surface is a horizontal plane. After the rotation axis of the rotary clamping mechanism 1 is adjusted to an inclined state, when the heat-insulated cup 200 rotates around the inclined rotation axis, the top axial can always maintain a horizontal state, thereby ensuring the effective pasting of the decorative paper and improving the decorative paper pasting quality of the heat-insulated cup with a gradually changed outer peripheral diameter in the axial direction.

[0054] The heating and rolling mechanism 2 includes a second driving member 21, a third support plate 22 driven by the second driving member 21 to move up and down, a fourth support seat 23 disposed below the third support plate 22, a decorative paper rolling wheel 24 rotatably disposed on the fourth support seat 23, a plurality of heaters 25 disposed on the fourth support seat 23 and surrounding the decorative paper rolling wheel 24, a protective cover 26 disposed on the fourth support seat 23 and enclosing the decorative paper rolling wheel 24 and the heaters 25 therein, and a third driving member 27 fixed on the fourth support seat 23 and driving the decorative paper rolling wheel 24 to rotate. An avoidance opening (not marked in the figure) is disposed below the protective cover 26, and the bottom of the outer peripheral surface of the decorative paper rolling wheel 24 extends out of the avoidance opening.

[0055] In this embodiment, the rotation power source of the thermos cup 200 is designed on the heating and rolling mechanism 2. First, the second driving member 21 is used to drive the decorative paper rolling wheel 24 to press down on the thermos cup 200 on the rotation clamping mechanism 1, and then the third driving member 27 is used to drive the decorative paper rolling wheel 24 to rotate, thereby driving the thermos cup 200 to rotate synchronously. In other embodiments, the rotation power source of the thermos cup 200 can also be designed on the rotation clamping mechanism 1, that is, the third driving member 27 is directly disposed on the first support plate 11 and drives the first rotation support member 12 or the second rotation support member 13 to perform a rotational motion. Since the thermos cup 200 is fixed in position on the rotation clamping mechanism 1 by means of internal support and shaft-end pressing, if the third driving member 27 is disposed on the rotation clamping mechanism 1 and drives the first rotation support member 12 or the second rotation support member 13 to rotate to drive the thermos cup to rotate, there may be a slipping phenomenon and it is impossible to reliably and stably drive the thermos cup to rotate. Therefore, preferably, the third driving member 27 is disposed on the heating and rolling mechanism 2.

[0056] The labeling pressure required for pasting different flower papers varies. In order to be applicable to the requirements of various flower paper rolling pressures and avoid damaging the flower paper due to the hard pressing of the flower paper rolling wheel 24 on the thermos cup 200, in this embodiment, a second hinge seat 28 is provided on the third support plate 22. One end of the fourth support seat 23 is rotatably arranged on the second hinge seat 28, and the other end is hung on the third support plate 22 through an angle adjustment screw (not shown in the figure). A spring (not shown in the figure) for pressing the fourth support seat 23 downward is provided on the angle adjustment screw. By rotatably arranging one end of the fourth support seat 23 on the second hinge seat 28 on the third support plate 22, the fourth support seat 23 has the freedom of angle adjustment. The height of the other end of the fourth support seat 23 is adjusted through the angle adjustment screw to realize the angle adjustment of the fourth support seat 23, and then the pressing angle of the flower paper rolling wheel 24 is adjusted, and then the pressing force of the flower paper is adjusted. By hanging one end of the fourth support seat 23 on the third support plate 22 through the angle adjustment screw and pressing the fourth support seat 23 downward through the spring, the end of the fourth support seat 23 pressed by the spring has the ability to float up and down, so as to realize the flexible pressing of the flower paper on the thermos cup and avoid damaging the flower paper.

[0057] The heater 25 can adopt an electric heating rod, or an infrared heating device, or ultrasonic heating, etc., which is not limited in this embodiment. The flower paper rolling wheel 24 is a rubber wheel. The flower paper rolling wheel 24 is heated by the heater 25, and then the flower paper rolling wheel 24 is used to contact the thermos cup to heat the thermos cup and the flower paper on the thermos cup. When the flower paper rolling wheel 24 heats the thermos cup, the flower paper rolling wheel 24 drives the thermos cup and the flower paper on the thermos cup to rotate synchronously to improve the heating uniformity.

[0058] The flower paper feeding mechanism 3 includes a flower paper support platform 31 and a fourth driving member 32 for driving the flower paper support platform 31 to move up and down to the upper tangent height position of the thermos cup on the rotary clamping mechanism 1. A plurality of air suction holes 33 for adsorbing the flower paper are arranged on the surface of the flower paper support platform 31. For thermos cups of different diameters, when they are fixed on the rotary clamping mechanism 1, there will be upper tangents at different heights. Therefore, in this embodiment, through the setting of the fourth driving member 32, the height of the flower paper support platform 31 can be flexibly adjusted according to the size of the thermos cup, so as to be compatible with thermos cups of various different diameters. The output end of the flower paper support platform 31 is close to the surface of the thermos cup, and the height of the flower paper support platform 31 is the same as the upper tangent height when the thermos cup is fixed on the rotary clamping mechanism 1, so that the un-pasted part of the flower paper can remain flat when the flower paper is pasted on the thermos cup.

[0059] The flower paper feeding mechanism 4 includes a material bin 41, a supporting bottom plate 42 arranged at the bottom of the material bin 41, and a fifth driving member 43 for driving the supporting bottom plate 42 to move up and down. A plurality of material separating elastic pieces 44 are arranged at the top of the material bin 41 to prevent the flower paper from being contaminated with materials.

[0060] The decal paper handling mechanism 5 includes a multi-axis robot 51 and a suction plate 52 disposed at the movable end of the multi-axis robot 51. The decal paper feeding mechanism 4 and the decal paper supporting mechanism 3 are both disposed within the working range of the multi-axis robot 51.

[0061] This embodiment further includes a baking conveyor line 6. The thermos cup with the decal paper pasted thereon is placed on the baking conveyor line 6 for high-temperature baking.

[0062] This embodiment also provides a decal pasting method implemented based on the automatic decal pasting device for thermos cups, which includes the following steps:

[0063] S1. Place the thermos cup 200 in a lying state on the rotary clamping mechanism 1. The first rotary support member 12 extends from the cup mouth end into the interior of the thermos cup 200, and the second rotary support member 13 axially presses the thermos cup 200 from the bottom end of the cup to fix the thermos cup 200.

[0064] S2. The decal paper handling mechanism 5 sucks a decal paper 300 from the decal paper feeding mechanism 4 and places it on the decal paper support platform 31 in the decal paper supporting mechanism 3. One end of the decal paper 300 extends above the top of the outer peripheral surface of the thermos cup 200. The suction holes 33 on the decal paper support platform 31 suck air to adsorb and fix the decal paper 300 to keep it flat. The decal paper handling mechanism 5 withdraws.

[0065] S3. The second driving member 21 in the heating and rolling mechanism 2 drives the decal paper rolling wheel 24 to descend. The decal paper rolling wheel 24 presses one end of the decal paper 300 tightly against the thermos cup 200. The third driving member 27 drives the decal paper rolling wheel 24 to rotate, and then drives the thermos cup 200 to rotate. Under the rotational clamping and conveying of the decal paper rolling wheel 24 and the thermos cup 200, and with the self-rotation follow-up of the thermos cup 200, the decal paper 300 is wrapped and pasted onto the outer peripheral surface of the thermos cup 200. At the same time, the heater 25 heats the decal paper rolling wheel 24, and through the contact between the decal paper rolling wheel 24 and the thermos cup 200, the heat is transferred to the thermos cup 200 to heat the thermos cup 200.

[0066] S4. When the temperature sensor 19 detects that the temperature of the thermos cup reaches the set temperature, the preliminary pasting of the decal paper is completed. Then the heating and rolling mechanism 2 rises, takes out the thermos cup 200 from the rotary clamping mechanism 1, and then places it on the baking conveyor line 6 for baking and curing.

[0067] For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
