Description

Technical Field

[0001] The invention relates to the field of capsule coffee packaging, in particular to a sealing film punching and sealing mechanism. Background Art

[0002] The cover film of traditional capsule coffee is prefabricated. The cover film is cut in advance according to the cup shape, and then sealed to the cup mouth through a heat sealing mechanism. This prefabricated cover film is more expensive than the cover film punched online, and the cover film will become unusable if the cup size changes slightly. In addition, this prefabricated cover film generally needs to be picked up and placed by a rotating suction cup mechanism, which has a large stroke and easily causes the cover film to be misaligned with the cup mouth, resulting in poor sealing.

[0003] For example, a Chinese patent with publication number CN218806802U discloses a film cutting mechanism for heat-sealing film, including a cutter lifting mechanism, a cutter die set and a film suction assembly, the cutter die set includes an inner hollow cutter and a cutting matching die, the inner hollow cutter has a hollow cavity that passes through from top to bottom, the cutting matching die is located below the inner hollow cutter, and a vertical through hole that matches the shape of the inner hollow cutter is provided on the cutting matching die, a channel for heat-sealing film to pass through is horizontally provided in the middle of the cutting matching die, the cutter lifting mechanism is connected to the inner hollow cutter, the film suction assembly includes an adsorption tube and a driving assembly for driving the adsorption tube to rise and fall, the adsorption tube extends into the hollow cavity of the inner hollow cutter, and the adsorption tube is connected to a negative pressure device. The film cutting mechanism of the heat-sealing film is provided with an inner hollow cutter, and a liftable adsorption tube is provided in the hollow cavity of the inner hollow cutter. The adsorption tube is used to suck the heat-sealing film tightly and place the cut heat-sealing film on the upper surface of the product to prevent the heat-sealing film from falling freely on the upper surface of the product, causing the film to fall off or shift easily, thereby ensuring the sealing effect of the finished product.

[0004] In summary, there are many disadvantages in the existing capsule coffee packaging methods, which are summarized as follows:

[0005] ① The traditional method of prefabricating the cover film is to cut the cover film according to the cup shape in advance, and then seal the prefabricated cover film to the cup mouth through a heat sealing mechanism. This kind of prefabricated cover film is more expensive than the cover film punched online, and the cover film will be unusable if the cup size changes slightly. In addition, this kind of prefabricated cover film generally needs to be taken and placed by a rotating suction cup mechanism, which has a large stroke and is easy to cause the cover film to be misaligned with the cup mouth, resulting in poor sealing and failure to achieve concentricity between the roll film and the capsule coffee;

[0006] ②Some structures integrate the cutter and the hot block, which is equivalent to a moving mold, which is easy to injure the operator during maintenance or operation;

[0007] ③During each cycle of ordinary equipment, the cutter is placed outside the hot block, and the heat is easily transferred to the cutter, which is particularly prone to burrs;

[0008] ④ The preheating time of traditional ironing blocks from startup to operation is relatively long. Summary of the invention

The advantage is that the knife is hidden in the base, and maintenance or operation The sealing head heating system starts and stops at positions away from the sealing film cutting knife device. For example, when the machine is stopped, the lowest heating block of the sealing head heating system is above the sealing film cutting knife device, which reduces the heat transferred to the sealing film cutting knife body. The cold cutting is done as much as possible during punching and cutting, which greatly reduces the generation of burrs. The punching and sealing of the sealing film roll are completed at the same station, and the sealing film roll is sucked by the negative pressure suction cup of the sealing head negative pressure system, ensuring the concentricity of the punched sealing film roll, the heating block, and the mouth of the capsule coffee cup, thereby ensuring excellent sealing airtightness. The sealing film cutting knife device adopts a hidden elastic floating design, so that the sealing film cutting knife body is retracted in the sealing film cutting knife device during daily shutdown.

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] A sealing film punching and sealing mechanism comprises a sealing film roll conveying system 31, a sealing total driving mechanism 32, a sealing head device 33, and a sealing film pressing and cutting device 34. The sealing total driving mechanism 32 is connected to the sealing head device 33, the sealing film pressing and cutting device 34 is located below the sealing head device 33, the sealing film roll conveying system 31 is located on both sides of the sealing film pressing and cutting device 34, and the sealing head device 33 and the sealing film pressing and cutting device 34 are concentrically arranged.

[0043] The sealing and film pressing and cutting knife device 34 includes a sealing and film pressing base 341, a sealing and film pressing telescopic device 342, a sealing and film pressing clamping plate 343, a sealing and cutting knife pressing plate 344, a sealing and cutting knife elastic member 345, a sealing and cutting knife limiting shaft 346, and a sealing and cutting knife body 347. The sealing and film pressing telescopic device 342 is arranged on the sealing and film pressing base 341, and the telescopic end is connected to the sealing and film pressing clamping plate 343 below the sealing and film pressing base 341. The sealing and cutting knife pressing plate 344 is limitedly arranged on the sealing and cutting knife limiting shaft 346, and can be embedded in the groove body of the sealing and film pressing base 341 on all sides. The sealing and cutting knife elastic member 345 is arranged on the sealing and cutting knife limiting shaft 346, and the sealing and cutting knife body 347 is connected to the sealing and cutting knife pressing plate 344.

[0044] In the normal non-working state, the bottom end of the sealing cutter body 347 is always retracted in the sealing film pressing cutter device 34, keeping a distance from the roll film, effectively avoiding contact between the operator and the blade, thereby effectively avoiding damage from the blade.

[0045] The sealing film roll conveying system 31 includes a sealing film roll roller 311 and a sealing film roll 312 . The sealing film roll roller 311 is arranged on both sides of the sealing film pressing and cutting knife device 34 . The sealing film roll 312 contacts the sealing film roll roller 311 and transitions between the sealing film pressing and cutting knife devices 34 .

[0046] The total sealing drive mechanism 32 includes a sealing drive motor 321, a sealing slide rail 322, and a sealing crank-connecting rod mechanism 323. The sealing drive motor 321 is connected to one end of the sealing crank-connecting rod mechanism 323, and the other end of the sealing crank-connecting rod mechanism 323 is connected to the sealing pressure head device 33. The sealing pressure head device 33 is limitedly set on the sealing slide rail 322.

[0047] The sealing head device 33 includes a sealing head base plate 331, a sealing head cylinder 332, a sealing head connecting shaft 333, a sealing head bearing seat 334, a sealing head cylinder driving block 335, a sealing head punching head 336, a sealing head fixing seat 337, a sealing head fixing shaft 338, and a sealing head heating and adsorption system 339.

[0048] The sealing pressure head substrate 331 is connected to the sealing total driving mechanism 32, the sealing pressure head cylinder 332 is fixed on both sides of the sealing pressure head substrate 331, the sealing pressure head cylinder 332 is connected to the sealing pressure head cylinder driving block 335, the sealing pressure head bearing seat 334 is fixed on the sealing pressure head substrate 331, and one end of the sealing pressure head connecting shaft 333 is sleeved inside, the sealing pressure head connecting shaft 333 is fixed on the sealing pressure head cylinder driving block 335, the other end of the sealing pressure head connecting shaft 333 is connected to the sealing pressure head punching pressure head 336, the sealing pressure head fixed seat 337 is connected to the sealing pressure head substrate 331, the sealing pressure head heating system 3391 is connected to the sealing pressure head fixed seat 337 through the sealing pressure head fixed shaft 338, and the sealing pressure head heating adsorption system 339 is connected to the sealing pressure head fixed shaft 338.

[0049] The sealing head fixing seat 337 is detachably mounted on the sealing head base plate 331, and the sealing head heating system 3391 and the sealing head negative pressure system 3392 in the sealing head heating and adsorption system 339 are modularly designed, which can facilitate the later replacement of spare parts such as the heating block 33911 or the negative pressure suction cup 33921.

[0050] The sealing pressure head heating and adsorption system 339 includes a sealing pressure head heating system 3391 and a sealing pressure head negative pressure system 3392. The sealing pressure head negative pressure system 3392 is arranged inside the center of the sealing pressure head heating system 3391. A negative pressure suction cup 33921 ​​is provided at the end of the sealing pressure head negative pressure system 3392. A heating block 33911 is provided at the end of the sealing pressure head heating system 3391.

[0051] The sealing head heating system 3391 is a ceramic heat sealing system, which quickly heats the heating block 33911. Compared with the traditional heating tube that takes 5 minutes to heat up to 150-200°C, the ceramic heat sealing system only takes 1 minute to complete the heating. It is worth noting that although the ceramic heat sealing system has no outstanding improvements, the key point is to ensure the concentricity of the sealing roll film 312, the heating block 33911 and the mouth of the capsule coffee cup, thereby ensuring excellent sealing airtightness. In addition, the modular and detachable design facilitates the replacement of spare parts such as thermocouples and heating blocks 33911 during later use, and the fast-heating ceramic heat sealing system can quickly meet production conditions.

[0052] The center position of the negative pressure suction cup 33921 ​​is in an X-shaped hollow shape.

[0053] Working mode: The sealing film roll roller 311 drives the sealing film roll 312 to move in steps. After one stepping cycle, the sealing film pressing telescopic device 342 contracts, and the sealing film pressing clamp 343 and the sealing film pressing base 341 are fitted to clamp the sealing film roll 312. The sealing drive motor 321 drives the sealing crank connecting rod mechanism 323 to drive the sealing pressure head device 33 to move on the sealing slide rail 322. The sealing pressure head cylinder 332 is in the extended state at this time. When the sealing pressure head device 33 is lowered, the sealing pressure head punching pressure head 336 contacts and presses down the sealing cutter pressing plate 344. The sealing cutter pressing plate 344 squeezes the sealing cutter elastic member 345 to drive the sealing cutter body 347 to complete the punching work of the sealing film roll 312. At the same time, the negative pressure suction cup 33921 ​​of the sealing pressure head negative pressure system 3392 absorbs the cut sealing film roll 312, and the punched sealing film roll 312 is located in the negative pressure The suction cup 33921 ​​is in the center position to ensure the overall concentricity, and the sealing head cylinder 332 is reset. At this time, the sealing head punching head 336 leaves the sealing cutter plate 344, and the sealing cutter body 347 retracts and returns to its original position. The sealing drive motor 321 continues to drive the sealing crank connecting rod mechanism 323 to drive the sealing head device 33 to move on the sealing slide rail 322. At this time, the heating block 33911 of the sealing head heating system 3391, the sealing film roll 312 cut by punching, and the cup mouth of the capsule coffee cup are in contact. The sealing film roll 312 completes the heat sealing work under the sealing temperature and pressure of the heating block 33911. When the sealing is completed, the negative pressure suction cup 33921 ​​in the center of the sealing module deflates and no longer adsorbs the sealing film roll 312. After completing the above actions, the sealing drive motor 321 reverses to drive the sealing head device 33 to move upward and return to the original position. At this point, a cycle action is completed.
