Description

Technical Field

[0001] The present invention relates to the technical field of packaging machinery, in particular to a paper cup edge rolling sealing machine. Background Art

[0002] A paper cup is a disposable container made of paper as the main raw material. It is usually cylindrical with an open and closed bottom. It is mainly used to hold liquids such as water, beverages, coffee, or some solid food. It is widely used in catering, office, outdoor activities and other scenarios because of its light weight, hygiene, low cost and no need to wash. It can be disposed of with domestic waste after use and is a common disposable item in daily life.

[0003] In some food and beverage areas, especially in the currently popular milk tea industry, when some drinks are made, the paper cups containing the drinks need to be sealed immediately to ensure the taste and hygiene of the drinks. Therefore, a paper cup edge rolling sealing machine is needed.

[0004] However, the existing paper cup edge rolling sealing machine has the following shortcomings:

[0005] The paper cup edge rolling sealing machines currently on the market rely on automated feeding and positioning systems to reduce the time required for manual intervention, and are equipped with high-frequency heating modules to shorten the heat-sealing time of a single seal. They perform relatively well in busier milk tea shops. However, as milk tea cups of various specifications and sizes gradually enter the market, the capacities and sizes of the cups used in them vary greatly. As a result, when purchasing sealing machines, it is necessary to purchase sealing machines of multiple mainstream sizes. When actually used in milk tea shops, the sealing quality of the milk tea is often substandard due to the wrong use of the corresponding sealing machine, resulting in a waste of materials and time.

[0006] Therefore, we propose a paper cup edge rolling sealing machine to solve the above problems. Summary of the Invention

Therefore, through the above operation, paper cups with different sizes of cup mouths can be sealed uniformly, without the need to replace multiple devices according to the size of the cup mouth, avoiding the problem of milk tea shops having to purchase multiple specifications of sealing machines, which increases costs, and avoids the situation where the wrong sealing machine is used, resulting in substandard milk tea sealing quality, thereby wasting materials and time.

[0021] 2. When the equipment of the present invention processes paper cups filled with liquid, in order to facilitate arbitrary placement and shorten the time, a third motor is installed between the paper cup placement plate and the filling block. The third motor drives the gear turntable to rotate through the spur gear, and then drives the rotation of multiple adjustment bars. Because the bottom of the adjustment bar is limited by the bottom turntable, the internal space of the adjustment bar can change size during rotation, thereby adjusting the position of the paper cup so that it is located at the corresponding position of the support block, avoiding subsequent misalignment and leakage.

The bottom of the fixed plate 202 is installed with a device plate 210, and the bottom of the device plate 210 is installed with a spring telescopic structure 212. The bottom of the spring telescopic structure 212 is installed with a heating module 213. The outer side of the heating module 213 is slidably connected to a heat insulating layer 215, and the inner side of the heat insulating layer 215 is slidably connected to a blade 216.

At this time, the electric telescopic rod mechanism 233 drives the multiple slot blocks 231 to tighten the paper cup through the multiple connectors 232. At the same time, the second motor 239 starts the filling strip formed by the storage filling blocks 235, so that the multiple slot blocks 23 The filling block 235 in 1 matches the circular groove formed by the multiple groove blocks 231. Thus, the multiple groove blocks 231 and the internal filling block 235 constitute a lifting ring with an arbitrarily variable ring size, automatically providing limited support for paper cups with different cup mouth sizes. When the multiple groove blocks 231 are driven to move, the sliding rod at the bottom thereof slides synchronously inside the slider 227, which is used to enhance the support for the paper cup during subsequent sealing. The limiting ring 230 slides in the limiting groove 229 opened by the sliding rod, and the top of the limiting ring 230 slides on the bottom of the filling block 235. The limiting ring 230 can be used to enhance the return of the filling ring to a circle when the separation distance between the multiple groove blocks 231 is large.

[0034] Example 2, according to Figure 4-Figure 6As shown, a telescopic spring 221 is provided on the inner side of the telescopic outer cylinder 220, a telescopic inner cylinder 222 is provided on the top of the telescopic spring 221, and the telescopic inner cylinder 222 is slidably connected to the inside of the telescopic outer cylinder 220, a second cylinder 219 is installed on the inner side of the bottom plate 218, a paper cup placement plate 224 is installed on the top of the second cylinder 219, and a distance sensor 225 is installed on the top of the paper cup placement plate 224.

A second motor 239 is installed at one end of the filling ring, and the second motor 239 is installed on the outside of the sealing machine body 1. A collecting bin 238 is installed on the top of the second motor 239. A fixed filling block 240 is installed at the other end of the filling ring. The fixed filling block 240 is located on the top inner side of the slot block 231, and a supporting slide bar 228 is installed at the bottom of the slot block 231.

The slider 227 is installed on the inner side of the mounting groove 226, and a guide bar 237 is installed on the outer side of the slot block 231 located on the outside of the second motor 239.

[0035] The effect achieved by the entire embodiment 2 is as follows: at this time, the device automatically starts the first cylinder 201 through the control chamber 4, and drives the multiple groups of heating modules 213, the insulation layer 215 and the blades 216 inside the insulation layer 215 downward through the fixing plate 202, pressing down on the top of the paper cup. Due to the different sizes of the openings of different paper cups, when the multiple groups of heating modules 213 contact the openings of the paper cups, the heating modules 213 in contact with the paper cups match the paper cups, and at the same time, the matching heating modules 213 stop pressing down due to the reaction force of the paper cups. The cylinder 201 continues to drive the fixed plate 202 downward until the electrode strip 211 on the device plate 210 contacts the electrode contact piece on the heating module 213. At this time, the corresponding heating module 213 starts heating to connect the sealing paper to the paper cup. After the corresponding heating module 213 is heated, the corresponding blade 216 is driven downward by the electric telescopic rod at its top to remove excess sealing paper. The second cylinder 219 starts again, driving the paper cup placement plate 224 and the sealed paper cup on it to descend. At this time, the sealing work is completed.

Another heating module 213 is located on the outside of the insulation layer 215, and another insulation layer 215 is located on the outside of the other heating module 213. The insulation layer 215 and the heating module 213 form a set of sealing structures. Another set of sealing structures is sleeved and located on the outside of the sealing structure. There are multiple sets of sealing structures at the bottom of the device plate 210. The inner side of the insulation layer 215 inside each set of sealing structures is correspondingly provided with blades 216 of different specifications. The blade 216 is cylindrical, and the contact electrode is composed of two electrode sheets, positive and negative. The electrode strip 211 is composed of two electrode assemblies, positive and negative. A control compartment 4 is provided on the top of the sealing machine body 1, and the first cylinder 201 is located on the inner side of the bottom of the control compartment 4.

[0037] The effect achieved by the entire embodiment 3 is as follows: when the paper cup is being sealed, the interior is mostly filled with liquid beverage. In order to allow the operator to freely place the paper cup at any position on the paper cup placement plate 224, thereby shortening the entire sealing time, a third motor 308 is provided between the paper cup placement plate 224 and the filling block 235 to drive the gear turntable 307 to rotate through the spur gear 309. At this time, the gear turntable 307 drives the multiple adjustment bars 306 to rotate. Because the bottom of the adjustment bar 306 is limited by the bottom turntable 305, when the multiple adjustment bars 306 rotate simultaneously, the space formed therein can change in size, thereby changing the position of the placed paper cup, so that the paper cup is located at the position corresponding to the support block, while avoiding misalignment and causing leakage in subsequent links.

[0038] The working principle of the whole device is as follows: first put the paper cup into the opening of the protective cover 234, let the bottom of the paper cup fall on the paper cup placement plate 224, press the button on the control chamber 4, the distance sensor 225 will measure the height of the paper cup, and then transmit the data to the control chamber 4, the control chamber 4 will automatically start the second cylinder 219, lift the paper cup placement plate 224 up until the edge of the paper cup is above the filling block 235, at this time, the electric telescopic rod mechanism 233 drives the multiple slot blocks 231 to clamp the paper cup through the multiple connectors 232, and at the same time, the second motor 239 starts to fill the filling block The filling strips formed by 235 are folded up, so that the filling blocks 235 in the multiple slot blocks 231 match the circular slots formed by these slot blocks. In this way, the multiple slot blocks 231 and the filling blocks 235 inside form a lifting ring that can arbitrarily change the ring size, automatically playing a limiting support role for paper cups of different cup sizes. When the multiple slot blocks 231 move, the sliding rod at the bottom will slide synchronously inside the slider 227, which helps to enhance the support for the paper cup during subsequent sealing. There is a sliding limiting ring 230 in the limiting groove 229 opened on the slide rod, and the top of the limiting ring 230 is in the filling ring. The bottom of the block 235 slides. When the separation distance of multiple slot blocks 231 is large, the limit ring 230 can help the filling ring to return to a round shape better. Then the equipment automatically starts the first cylinder 201 through the control chamber 4, and drives the multiple groups of heating modules 213, the insulation layer 215 and the blades 216 in the insulation layer 215 to press downward with the help of the fixing plate 202, and move toward the top of the paper cup. Due to the different sizes of the openings of different paper cups, when the multiple groups of heating modules 213 contact the openings of the paper cups, those heating modules 213 that are in contact with the paper cups will match the paper cups and be affected by the reaction force of the paper cups. The downward pressure stops, but the first cylinder 201 will continue to drive the fixed plate 202 downward until the electrode strip 211 on the device plate 210 contacts the electrode contact piece on the heating module 213. At this time, the corresponding heating module 213 starts heating, connecting the sealing paper and the paper cup. After the corresponding heating module 213 completes heating, its corresponding blade 216 will be driven by the top electric telescopic rod to press down and cut off the excess sealing paper. Then, the second cylinder 219 starts again, driving the paper cup placement plate 224 and the sealed paper cup on it to descend, and the sealing work is completed.

[0039] In order to allow the operator to place the paper cup at any position on the paper cup placement plate 224, thereby shortening the overall sealing time, between the paper cup placement plate 224 and the filling block 235, the third motor 308 drives the gear turntable 307 to rotate through the spur gear 309, and the gear turntable 307 then drives the multiple adjustment bars 306 to rotate. Because the bottom of the adjustment bar 306 is limited by the bottom turntable 305, when the multiple adjustment bars 306 rotate synchronously, the size of the space formed between them will change, so that the position of the paper cup placed on it can be adjusted so that it is precisely aligned with the corresponding position of the support block, effectively avoiding liquid leakage in subsequent operations due to position offset.
