Description
Technical Field
[0001] The present application relates to the field of aluminum foil paper processing, and in particular to a cutting device and a packaging machine for aluminum foil paper. Background Art
[0002] Currently, for reasons such as aesthetics, some cigarette boxes need to be made transparent in the flip part of the cigarette box to display the filter tips of the cigarettes inside. Among them, since there is a layer of aluminum foil paper laid inside the cigarette box, the aluminum foil paper blocks the filter tips, resulting in the inability to see the filter tips from the outside of the cigarette box. Therefore, a cutting device is required to cut the aluminum foil paper.
[0003] In the related art, the cutting device includes a conveying frame, a cutting knife and a driving member. The conveying frame includes a traction assembly, a limiting assembly and a cutting seat. The traction assembly realizes the transportation of the aluminum foil paper, the limiting assembly realizes the limitation of the transportation of the aluminum foil paper, and the driving member drives the cutting knife to approach or move away from the cutting seat to realize the cutting of the aluminum foil paper.
[0004] However, in actual application, during the process of the driving member driving the cutting knife to approach the cutting seat, the traction assembly needs to stop the transportation of the aluminum foil paper to ensure the stability of cutting. In this way, the intermittent transportation of the aluminum foil paper is caused, resulting in a low cutting efficiency of the aluminum foil paper. Therefore, improvement is needed. Utility Model Content
[0005] In order to improve the cutting efficiency of aluminum foil paper, in a first aspect, the present application provides a cutting device for aluminum foil paper.
[0006] The cutting device for aluminum foil paper provided by the present application adopts the following technical solutions:
[0007] A cutting device for aluminum foil paper includes a mounting frame, a rotating roller, a cutting knife roller and a driving member; the rotating roller and the cutting knife roller are both rotatably connected to the mounting frame, a conveying channel for the aluminum foil paper to pass through is formed between the rotating roller and the cutting knife roller, and cutting blocks are arranged on the circumferential side of the cutting knife roller; a first gear is arranged at one end of the rotating roller, a second gear is arranged at one end of the cutting knife roller, and the first gear meshes with the second gear; the driving member is arranged on the mounting frame and drives the rotating roller to rotate.
[0008] By adopting the above technical solutions, in actual application, the aluminum foil paper passes through the conveying channel between the rotating roller and the cutting knife roller. The driving member drives the rotating roller to rotate. Under the action of the first gear and the second gear, the cutting knife roller rotates in the reverse direction, thereby driving the aluminum foil paper to move, that is, realizing the transportation of the aluminum foil paper. During this process, when the cutting blocks come into contact with the rotating roller, the cutting of the aluminum foil paper can be realized, so that the aluminum foil paper is continuously transported and cut, thereby improving the cutting efficiency of the aluminum foil paper.
[0009] Preferably, the cutting device further includes an air pump. The cutting block is hollow and has a ventilation hole on the side away from the cutter roller. The air pump is arranged on the mounting rack and is communicated with the inside of the cutting block.
[0010] By adopting the above technical solution, by setting the air pump, when the cutting block cuts the aluminum foil paper, the air pump evacuates the inside of the cutting block, so that the cut aluminum foil sheet is adsorbed on the cutting block. After the cutter roller rotates a certain angle, the air pump stops evacuating the inside of the cutting block, and at this time the aluminum foil sheet drops, avoiding affecting the next cutting of the cutting block.

[0013] Preferably, the cutter roller is provided with a mounting groove, and the cutting block is arranged in the mounting groove.
[0014] By adopting the above technical solution, by setting the mounting groove, the thickness of the cutting block is ensured, so as to ensure that there is a certain space inside the cutting block, and further ensure the stability of the gas flow inside the cutting block.
[0015] Preferably, the cutting device further includes a material collecting component. The material collecting component includes a material collecting hopper, and the material collecting hopper is located below the cutter roller.

[0017] Preferably, the material collecting component further includes a base. The material collecting hopper is arranged on the base, and the base is arranged on the mounting rack.

[0019] Preferably, the material collecting component further includes an exhaust pipe. The exhaust pipe is arranged on the material collecting hopper and is communicated with the inside of the material collecting hopper.
[0020] By adopting the above technical solution, an air extraction pipe is provided and connected to an external air extractor. When the aluminum foil sheets in the material receiving hopper are relatively full, the air extractor operates to extract the aluminum foil sheets in the material receiving hopper, facilitating the subsequent collection of aluminum foil sheets.

[0022] The packaging machine provided by the present application adopts the following technical solution:
[0023] A packaging machine includes the cutting device described above.
[0024] In summary, the present application includes at least one of the following beneficial technical effects:
[0025] 1. In practical applications, the aluminum foil passes through the conveying channel between the rotating roller and the cutter roller. The driving member drives the rotating roller to rotate. Under the action of the first gear and the second gear, the cutter roller rotates in the opposite direction, thereby driving the aluminum foil to move, that is, realizing the conveying of the aluminum foil. During this process, when the cutting block contacts the rotating roller, the cutting of the aluminum foil can be achieved, enabling the continuous conveying and cutting of the aluminum foil, thus improving the cutting efficiency of the aluminum foil.
[0026] 2. By providing an air pump, when the cutting block cuts the aluminum foil, the air pump extracts air inside the cutting block, causing the cut aluminum foil sheets to be adsorbed to the cutting block. After the cutter roller rotates a certain angle, the air pump stops extracting air inside the cutting block, and at this time the aluminum foil sheets fall off, avoiding affecting the next cutting of the cutting block.
[0027] 3. By providing an air inlet and an air outlet, the extraction and inflation of air inside the cutting block are realized, so as to adsorb the cut aluminum foil sheets and stably separate the aluminum foil sheets from the cutting block, and the extraction and inflation of air inside the cutting block do not interfere with each other, ensuring the stability of the air pump for extracting and inflating air inside the cutting block.

[0033] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0034] The following is further described in detail with reference to the attached Figures 1-3 drawings for this application.
[0035] An embodiment of this application discloses a cutting device for aluminum foil.
[0036] Referring to Figure 1 and Figure 2 , the cutting device includes a mounting bracket 1, a rotating roller 2, a cutting roller 3, and a driving member 4. The rotating roller 2 and the cutting roller 3 are both rotatably connected to the mounting bracket 1. The rotating roller 2 and the cutting roller 3 are arranged in parallel, and a conveying channel 5 for the aluminum foil 8 to pass through is formed between the rotating roller 2 and the cutting roller 3. A cutting block 31 protrudes from the circumferential side of the cutting roller 3, and the cutting block 31 is in contact with the rotating roller 2 to realize the cutting of the aluminum foil 8.
[0037] A first gear 21 is fixedly connected to one end of the rotating roller 2. At the same time, a second gear 32 is fixedly connected to one end of the cutting roller 3. The first gear 21 and the second gear 32 are meshed with each other. In this embodiment, the driving member 4 is a motor. The driving member 4 is fixedly connected to the mounting bracket 1, and the power output shaft of the driving member 4 is fixedly connected to the rotating roller 2 to drive the rotating roller 2 to rotate.
[0038] In practical applications, first, the aluminum foil paper 8 passes through the conveying channel 5 formed between the rotating roller 2 and the cutter roller 3. The staff starts the driving member 4, so that the driving member 4 drives the rotating roller 2 to rotate, driving the first gear 21 to rotate. Since the first gear 21 meshes with the second gear 32, the second gear 32 is driven to rotate, causing the cutter roller 3 to rotate in the reverse direction, thereby driving the aluminum foil paper 8 located in the conveying channel 5 to move, that is, realizing the conveyance of the aluminum foil paper 8. During this process, the cutter roller 3 rotates, causing the cutting block 31 to intermittently contact the rotating roller 2, thus realizing the cutting of the aluminum foil paper 8, enabling the continuous conveyance and cutting of the aluminum foil paper 8, and thereby improving the cutting efficiency of the aluminum foil paper 8.
[0039] In some embodiments, the cutting device further includes an air pump 6. The cutting block 31 is hollow, and an air vent 33 is provided on the side of the cutting block 31 away from the cutter roller 3 (i.e., the outside of the cutting block 31), and the air vent 33 is in communication with the inside of the cutting block 31. The air pump 6 is fixedly connected to the mounting frame 1 and is in communication with the inside of the cutting block 31. When the cutting block 31 cuts the aluminum foil paper 8, the air pump 6 evacuates the inside of the cutting block 31, causing the cut aluminum foil sheet 9 to be adsorbed to the cutting block 31. After the aluminum foil paper 8 is cut, the cutter roller 3 rotates a certain angle. At this time, the air pump 6 stops evacuating the inside of the cutting block 31, so that the aluminum foil sheet 9 drops, minimizing the impact of the aluminum foil sheet 9 on the cutting work of the cutting block 31.
[0040] Refer to Figure 1 and Figure 3 In some embodiments, an air inlet 34 and an air outlet 35 are provided at one end of the cutter roller 3, and the air inlet 34 and the air outlet 35 are both in communication with the inside of the cutting block 31. The air pump 6 is a combined suction and blowing pump. The suction end of the air pump 6 is connected to the air outlet 35 through a trachea, so that the suction end of the air pump 6 is in communication with the air outlet 35. The inflation end of the air pump 6 is connected to the air inlet 34 through a trachea, so that the inflation end of the air pump 6 is in communication with the air inlet 34. Through the air pump 6, the evacuation and inflation of the inside of the cutting block 31 can be realized, so as to adsorb the cut aluminum foil sheet 9 and stably separate the aluminum foil sheet 9 from the cutting block 31. At the same time, since the air inlet 34 and the air outlet 35 are separately arranged, the evacuation and inflation of the inside of the cutting block 31 do not interfere with each other, ensuring the stability of the evacuation and inflation of the inside of the cutting block 31 by the air pump 6.
[0041] Refer to Figure 3 In some embodiments, the cutter roller 3 is provided with a mounting groove 36, and the cutting block 31 is arranged in the mounting groove 36 to ensure that the cutting block 31 has a certain thickness, thereby ensuring that there is a certain space inside the cutting block 31, and further ensuring the stability of the gas flow inside the cutting block 31. Moreover, it can make the distance between the rotating roller 2 and the cutter roller 3 smaller, ensuring the stability of the transportation of the aluminum foil paper 8.
[0042] In some embodiments, the cutting device further includes a material receiving assembly 7. The material receiving assembly 7 includes a material receiving hopper 71 which is arranged in a horn shape and is located below the cutter roller 3. When the cutter roller 3 is at the position of the cut block 31 directly above the material receiving hopper 71, the air pump 6 stops evacuating the inside of the cut block 31 and inflates the inside of the cut block 31, so that the cut aluminum foil sheet 9 quickly falls into the material receiving hopper 71, realizing the collection of the aluminum foil sheet 9 falling from the cut block 31, and trying to avoid the random flying of the aluminum foil sheet 9 to ensure the cleanliness of the cutting device during operation.
[0043] In some embodiments, the material receiving assembly 7 further includes a base 72. The base 72 is fixedly connected to the mounting frame 1 by bolts, and the material receiving hopper 71 is fixedly connected to the base 72 to realize the installation of the material receiving hopper 71.
[0044] In some embodiments, the material receiving assembly 7 further includes an exhaust pipe 73. The exhaust pipe 73 is fixedly connected to one side of the material receiving hopper 71, and the exhaust pipe 73 is communicated with the inside of the material receiving hopper 71 and is connected to an external exhaust fan (not shown in the figure). When the aluminum foil sheets 9 in the material receiving hopper 71 are relatively full, the exhaust fan operates to extract the aluminum foil sheets 9 in the material receiving hopper 71, facilitating the subsequent material receiving of the aluminum foil sheets 9.
[0045] The implementation principle of this embodiment is as follows: In practical applications, first pass the aluminum foil paper 8 through the conveying channel 5 formed between the rotating roller 2 and the cutter roller 3. The staff starts the driving member 4, so that the driving member 4 drives the rotating roller 2 to rotate, driving the first gear 21 to rotate. Since the first gear 21 meshes with the second gear 32, it drives the second gear 32 to rotate, causing the cutter roller 3 to rotate in the reverse direction, thereby driving the aluminum foil paper 8 located in the conveying channel 5 to move, that is, realizing the conveying of the aluminum foil paper 8. During this process, the cutter roller 3 rotates, so that the cut block 31 intermittently contacts the rotating roller 2, and the cutting of the aluminum foil paper 8 can be realized, enabling the continuous conveying and cutting of the aluminum foil paper 8, thereby improving the cutting efficiency of the aluminum foil paper 8.
[0046] The embodiment of the present application also discloses a packaging machine.
[0047] The packaging machine includes the cutting device described in the above embodiment.
[0048] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
