Description

Technical Field

[0001] The invention relates to a paper can sealing machine and a can sealing method, belonging to the technical field of paper can processing equipment. Background Art

[0002] A paper can sealer is an automated packaging machine used to seal paper tubes (cans) with metal or plastic lids. It is widely used in packaging for food, tea, cosmetics, pharmaceuticals, and other industries. Its core function is to securely bond the lid to the can through mechanical pressure or heat sealing technology, ensuring the product's airtightness, moisture resistance, and aesthetics.

[0003] For paper can sealing machines that use heat sealing technology, it is only necessary to control the discharge mechanism to place the aluminum foil sealing film on the mouth of the paper can, and then control the hot pressing module to heat press the sealing film to simultaneously achieve the sealing of the paper can; the mouth of a conventional paper can is set horizontally, and the sealing film is placed horizontally on the mouth of the can. The hot pressing module of the paper can sealing machine uses a flat pressing method to heat seal the paper can; However, there is currently a paper can with an oblique mouth, as shown in the attached manual. Figure 1 As shown in the figure, the mouth of the paper can 01 is in an inclined state, and the heat-sealing film is also in an inclined state after covering the inclined mouth of the can. However, the heat-pressing module on the conventional paper can sealing machine is difficult to effectively heat-seal the inclined heat-sealing film by using a flat heat-pressing method, so improvement is needed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a paper can seaming machine, which improves the problem in the prior art that the paper can seaming machine is difficult to be compatible with sealing paper cans with inclined can mouths.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions: A paper can sealing machine is used to seal paper cans with tilted can openings; it comprises a feeding mechanism, a transfer mechanism, a capping mechanism, and a sealing mechanism; the feeding mechanism transports the paper cans to the transfer mechanism, and the transfer mechanism drives the paper cans to pass through the capping mechanism and the sealing mechanism in sequence; The transfer mechanism includes a transfer platform, a turntable, and a rotation driving source for controlling the rotation of the turntable. The transfer platform is located below the cap placement mechanism and the sealing mechanism. A plurality of clamping grooves are evenly arranged on the turntable. The feeding mechanism drives the paper can into the clamping grooves. The inner wall of the clamping groove corresponds to the lower end of the side wall of the paper can. The invention also includes an adjustment device, the adjustment device includes an adjustment disk, the rotation drive source simultaneously controls the rotation of the adjustment disk, the adjustment disk is evenly arranged with a plurality of adjustment grooves corresponding to the clamping grooves, the feeding mechanism simultaneously drives the paper can into the adjustment grooves, the inner wall of the adjustment groove corresponds to the upper end of the side wall of the paper can, and the turntable and the adjustment disk simultaneously drive the paper can to rotate; The capping mechanism is provided with a cap, the top of which is inclined in the same manner as the mouth of the paper can, and a sealing film is provided inside the cap. The capping mechanism controls the cap to be vertically covered on the mouth of the paper can. The adjusting disk can rotate relative to the turntable at a specified angle. During the simultaneous rotation of the adjusting disk and the turntable, when the adjusting disk rotates relative to the turntable at a specified angle, one inner wall of the adjusting groove abuts against the upper end of the side wall of the paper can, and one inner wall of the clamping groove abuts against the lower end of the other side wall of the paper can. The adjusting disk drives the upper end of the paper can to tilt toward one side, the mouth of the paper can is horizontally arranged, and one side of the bottom of the paper can abuts against the transfer platform, while the other side is lifted relative to the transfer platform. The adjusting device further comprises a limiting assembly. When the adjusting disk and the rotating disk rotate simultaneously, the limiting assembly can abut against the adjusting disk to enable the adjusting disk to rotate relative to the rotating disk.

[0006] By adopting the above technical solution, the paper can with tilted mouth enters the transfer mechanism from the feeding mechanism, the upper end of the paper can is located in the adjustment groove, and the lower end of the paper can is located in the clamping groove. The paper can is driven by the adjustment disk and the turntable to rotate to the transfer platform; when the paper can reaches the capping mechanism, the capping mechanism controls the cap pre-installed with aluminum foil sealing film to fall vertically onto the mouth of the paper can, and the cap is closed on the mouth of the paper can; During the process of transferring the paper can to the sealing mechanism, when the paper can is about to rotate into place, the limit assembly abuts the adjusting disk, and the adjusting disk stops rotating after encountering resistance. The adjusting disk rotates relative to the turntable, and the turntable applies a force to one side on the lower end of the side wall of the paper can, and the adjusting disk applies an opposite force to the upper end of the other side wall of the paper can, so that the paper can is tilted and the mouth of the paper can is horizontal. The sealing mechanism uses a flat pressing method to hot-press the cover on the paper can, and the sealing film seals the mouth of the paper can.

[0007] The present invention is further configured as follows: the adjustment device also includes a plurality of bottom support members corresponding one to one with the clamping grooves, the bottom support members are rotatably connected to the turntable, and when the adjustment disk rotates relative to the turntable, the bottom support members can abut against the raised side of the bottom of the paper can.

[0008] By adopting the above technical solution, when the paper can is tilted, one side of the bottom is lifted. When the paper can is hot-pressed through the heat sealing mechanism, the pressure is concentrated on one side of the bottom of the paper can. There is a situation where the contact surface of the bottom of the paper can is deformed, and the single-point support of the bottom of the paper can is not stable. The bottom support assembly plays a supporting and stabilizing role, so that the pressure on the bottom of the paper can is evenly distributed, and the paper can is more stable.

[0009] The present invention is further configured such that: a linkage assembly is provided between the adjusting disk and the bottom supporting member, and the adjusting disk drives the bottom supporting member to rotate through the linkage assembly.

[0010] By adopting the above technical solution, the linkage component is connected in series with the bottom support and the adjustment disk, and the overall synchronization is higher.

[0011] The present invention is further configured as follows: the linkage assembly includes a linkage ring and a connecting rod, the linkage ring is coaxially rotatably connected to the turntable, the bottom support is arranged on the linkage ring, and the connecting rod is respectively connected to the linkage ring and the adjustment disk.

[0012] By adopting the above technical solution, the linkage ring is connected in series with the bottom supporting member and the adjusting disk, so that the adjusting disk can drive the bottom supporting member to rotate.

[0013] The present invention is further configured such that: the adjusting device further comprises a side support member and a side support driving source for controlling the movement of the side support member, and the side support driving source can drive the side support member to abut against the tilted side of the paper can.

[0014] By adopting the above technical solution, after the paper can tilts to one side, the tilted side of the paper can is not stable and there is a risk of the paper can continuing to tilt. Therefore, the side support is used to support the tilted side of the paper can, so that the paper can remains stable after tilting.

[0015] The present invention is further configured as follows: a pressure sensor connected to the side support driving source signal is provided on the bottom support member, and when the bottom support member abuts against the bottom of the paper can, the pressure sensor simultaneously abuts against the bottom of the paper can.

[0016] By adopting the above technical solution, after the bottom support member abuts against the bottom of the paper can, the pressure sensor receives pressure data from the bottom of the paper can, and the pressure sensor controls the side support driving source to work and drive the side support member to contact the paper can. After the paper can is separated from the bottom support member, the pressure sensor controls the side support member to reset, and the side support member will not interfere when sealing the flat-mouth paper can.

[0017] The present invention is further configured as follows: the limiting assembly includes a limiting member and a limiting driving source for controlling the movement of the limiting member, and the limiting driving source can drive the limiting member to abut against the side wall of the adjusting disk.

[0018] By adopting the above technical solution, after the limiting member contacts the side wall of the adjusting disk, the adjusting disk stops rotating, while the turntable continues to rotate by a certain angle, so that the turntable and the adjusting disk rotate relative to each other.

[0019] The present invention is further configured such that a torsion spring is provided between the adjusting disk and the output shaft of the rotation drive source for returning the adjusting disk to its original position after rotating relative to the rotating disk.

[0020] By adopting the above technical solution, the adjusting disk is reset by the setting of the torsion spring, and at the same time, it can prevent the turntable and the adjusting disk from accidentally rotating relative to each other during the process of rotating together.

[0021] The present invention also provides a paper can sealing method, which improves the problem in the prior art that paper cans with inclined can mouths are difficult to seal.

[0022] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions: A paper can sealing method, using a paper can sealing machine according to any one of claims 1 to 8, comprising the following steps: (1) Place the paper can with the mouth tilted horizontally on the loading mechanism. The loading mechanism transports the paper can to the transfer mechanism. The turntable and the adjustment disk rotate together and drive the paper can to the bottom of the capping mechanism on the transfer table. (2) The sealing film is placed in the cover in advance, and the cover is filled into the cover placing mechanism. The cover placing mechanism controls the cover to fall vertically onto the mouth of the paper can. The cover is closed on the mouth of the paper can, and the top of the cover, the sealing film and the mouth of the paper can are parallel; (3) The turntable and the adjusting disk continue to rotate and drive the paper can to rotate toward the bottom of the capping mechanism. After the paper can rotates to the specified position, the limit assembly abuts the adjusting disk, the adjusting disk stops rotating, and the turntable continues to rotate at a specified angle and then stops. The adjusting disk rotates relative to the turntable, the adjusting disk abuts the upper end of the side wall of the paper can, and the turntable abuts the lower end of the side wall of the paper can. The paper can tilts to one side, and the mouth of the paper can is horizontal. One side of the bottom of the paper can is lifted relative to the transfer platform, and the other side abuts on the transfer platform. (4) The adjusting plate drives the bottom support member to abut against the raised side of the bottom of the paper can to support the bottom of the paper can, and the pressure sensor receives the pressure data of the paper can on the bottom support member to control the side support member to abut against the tilted side of the paper can, and the side support member supports the side of the paper can; (5) The sealing mechanism performs horizontal hot pressing on the sealing cap of the paper can, and the aluminum foil sealing film inside the sealing cap seals the mouth of the paper can; (6) After the sealing operation is completed, the limit assembly is reset and separated from the adjustment disk. The adjustment disk is reset under the action of the torsion spring. The adjustment disk reverses to drive the paper can to return to the horizontal level and the bottom support to reset. The pressure sensor receives the pressure data and controls the side support to reset.

[0023] The beneficial effects of the present invention are: 1. For paper cans with tilted mouths, the sealing film is placed in the cover in advance, and then the cover is closed on the mouth of the paper can by the cover placement mechanism, so that the sealing film stays stably on the mouth of the paper can, avoiding the risk of the sealing film slipping after being placed directly on the mouth of the paper can; 2. After the adjustment disk rotates relative to the turntable, the paper can is tilted to one side, so that the originally tilted paper can mouth is horizontal, so that the sealing mechanism can perform flat pressure sealing. Moreover, when it comes to paper cans with flat mouths, since the sealing mechanism always adopts the flat pressure sealing method, the paper can seaming machine provided by the present application can still be used normally; 3. After the paper can is tilted, the bottom support and side support respectively support the bottom and side wall of the paper can, thereby protecting and stabilizing the paper can.

The paper can sealing machine provided in the present application also includes an adjusting device 500, which includes an adjusting disk 50. The rotating driving source 22 simultaneously controls the rotation of the adjusting disk 50. A plurality of adjusting grooves 501 corresponding to the clamping grooves 201 are evenly arranged on the adjusting disk 50. The loading mechanism 100 simultaneously drives the paper can 1 into the adjusting groove 501. The inner wall of the adjusting groove 501 corresponds to the upper end of the side wall of the paper can 1. The turntable 21 and the adjusting disk 50 simultaneously drive the paper can 1 to rotate, and the paper can 1 leaves the conveyor belt and is transferred to the transfer platform 20.

[0036] The cap placing mechanism 300 includes a cap placing bracket, on which a storage platform 30 is provided.

[0037] The adjustment disk 50 is capable of rotating relative to the turntable 21 by a specified angle. During simultaneous rotation of the adjustment disk 50 and the turntable 21, when the adjustment disk 50 rotates relative to the turntable 21 by the specified angle, the inner wall of one side of the adjustment groove 501 abuts the upper end of the side wall of the paper can 1, and the inner wall of one side of the clamping groove 201 abuts the lower end of the other side wall of the paper can 1. The adjustment disk 50 causes the upper end of the paper can 1 to tilt toward one side, the mouth of the paper can 1 being horizontally disposed, and one side of the bottom of the paper can 1 abuts the transfer platform 20, while the other side is raised relative to the transfer platform 20. A torsion spring (not shown in the drawings) is provided between the adjustment disk 50 and the output shaft of the rotation drive source 22 to reset the adjustment disk 50 after rotation relative to the turntable 21.

[0038] The adjustment device 500 also includes a limit assembly. When the adjustment disk 50 and the turntable 21 rotate simultaneously, the limit assembly can abut the adjustment disk 50, thereby rotating the adjustment disk 50 relative to the turntable 21. The limit assembly includes a limit member 51 and a limit drive source 52 for controlling the movement of the limit member 51.

The bottom support members 53 are detachably mounted on the linkage ring. The connecting rod 55 is detachably connected to the linkage ring 54 and the adjustment disk 50. Specifically, the number of the bottom support members 53 corresponds to the clamping groove 201, and a receiving groove is opened on the turntable 21. The bottom support member 53 is arranged in the corresponding receiving groove. The bottom support member 53 has a support end 531 that abuts against the bottom of the paper can 1. The support end 531 is an inclined surface that is matched with the bottom of the paper can 1 after being tilted.

The turntable (21) and the adjustment disk (50) rotate together and drive the paper can (1) to rotate to the bottom of the cover placement mechanism (300) on the transfer platform (20); (2) The sealing film (2) is placed in the sealing cover (3) in advance, and the sealing cover (3) is filled into the capping mechanism (300). The capping mechanism (300) controls the sealing cover (3) to fall vertically onto the mouth of the paper can (1). The sealing cover (3) is closed on the mouth of the paper can (1), and the top of the sealing cover (3), the sealing film (2) and the mouth of the paper can (1) are in a parallel state. (3) The turntable (21) and the adjusting disk (50) continue to rotate and drive the paper can (1) to rotate toward the bottom of the capping (3) mechanism. After the paper can (1) rotates to the specified position, the limit assembly abuts the adjusting disk (50), the adjusting disk (50) stops rotating, the turntable (21) continues to rotate at a specified angle and then stops. The adjusting disk (50) rotates relative to the turntable (21). The adjusting disk (50) abuts the upper end of the side wall of the paper can (1), and the turntable (21) abuts the lower end of the side wall of the paper can (1). The paper can (1) tilts to one side, and the mouth of the paper can (1) is in a horizontal state. One side of the bottom of the paper can (1) is lifted relative to the transfer platform (20), and the other side abuts on the transfer platform (20); (4) The adjusting plate (50) drives the bottom supporting member (53) to abut against the raised side of the bottom of the paper can (1) to support the bottom of the paper can (1), and the pressure sensor receives the pressure data of the paper can (1) on the bottom supporting member (53) to control the side supporting member (56) to abut against the tilted side of the paper can (1), and the side supporting member (56) supports the side of the paper can (1); (5) The sealing (3) mechanism performs horizontal heat pressing on the sealing (3) on the paper can (1), and the aluminum foil sealing film (2) in the sealing (3) seals the mouth of the paper can (1); (6) After the sealing operation is completed, the limit assembly is reset and separated from the adjustment disk (50). The adjustment disk (50) is reset under the action of the torsion spring. The adjustment disk (50) reverses to drive the paper can (1) to return to the horizontal position and the bottom support (53) to reset. The pressure sensor receives the pressure data and controls the side support (56) to reset.
