Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging machine technology, and in particular to a channel guide plate based on microporous air cushion. Background Technology

[0002] During the production process of the YB416 small box packaging machine, the frame paper rubs against the guide plate surface under the positive pressure of the cigarette pack, resulting in scratches. Specifically, wheel number three is the aluminum foil cigarette pack conveyor wheel and also the receiving wheel where the frame paper is embedded under the cigarette pack. The lower guide plate of this wheel is divided into two sections: the first section is from 3 o'clock to 6 o'clock, and the second section is from 6 o'clock to 9 o'clock. The frame paper is embedded under the mold box of wheel number three through the gap between the first and second guide plates, and is conveyed together with the aluminum foil cigarette pack in the mold box to the 9 o'clock position of wheel number three, where it is pushed into the mold box of wheel number four. The section from 3 o'clock to 6 o'clock of wheel number three is equipped with negative pressure suction. Through the negative pressure suction holes on the inner wall of the mold box, the aluminum foil cigarette pack is adsorbed into the mold box, so that there is no obvious contact between the aluminum foil cigarette pack and the lower guide plate, and there is a certain gap between them, allowing the frame paper to be smoothly embedded into the second guide plate under the mold box of wheel number three, and then conveyed forward together with the aluminum foil cigarette pack. The second section of the mold box from 6 o'clock to 9 o'clock on the third wheel no longer has negative pressure suction. The aluminum foil cigarette pack falls directly above the frame paper, generating a positive pressure on the frame paper. During the rotation and conveying of the third wheel, the frame paper and the second section guide plate will undergo relative displacement, causing the surface of the frame paper to rub against the guide plate, resulting in scratches on the surface of the frame paper.

[0003] The existing on-site handling solution mainly involves polishing the lower guide plate to reduce friction, but the frame paper of the cigarette pack still shows obvious scratches, thus affecting the appearance and packaging quality of the product. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a channel guide plate based on microporous air cushion to solve the problem of obvious scratches on the cigarette pack frame paper in the prior art.

[0005] This utility model solves the above-mentioned technical problems through the following technical means: a channel guide plate based on microporous air cushion, including a panel and a guide plate body, wherein a plurality of micropores in a fan-shaped array are opened on the panel, and a groove is opened on the guide plate body corresponding to the area of ​​the micropores, and the panel and the guide plate body are sealed to form a cavity communicating with the micropores.

[0006] The guide plate body is provided with a connector that communicates with the cavity. The connector is used to communicate with a positive pressure air source. A stable air film layer with a thickness of 5-50μm is formed at the interface between the panel surface and the frame paper. A self-lubricating coating is applied to the panel surface corresponding to the air film layer.

[0007] Optionally, the self-lubricating layer is a polytetrafluoroethylene (PTFE) composite material layer. To further improve the stability of the air film layer and prevent rough panel surfaces from disrupting its continuity, the PTFE composite material layer has a very smooth surface, which greatly reduces the turbulent resistance of the airflow.

[0008] Optionally, the groove is provided with a plurality of bosses, one end of which is used to abut against the panel, and the other end is provided with internal threads for use with screws on the panel for fastening.

[0009] Optionally, the diameter of the micropores ranges from 0.5 mm to 1 mm. This, combined with a pressure source, forms a stable gas film layer.

[0010] Optionally, a sealant is applied between the panel and the guide plate body to enhance the sealing of the cavity.

[0011] Optionally, the thickness of the panel is 1 / 4 of the thickness of the channel guide plate, and the thickness of the guide plate body is 3 / 4 of the thickness of the channel guide plate.

[0012] Optionally, the guide plate body has several threaded holes on the edge of the groove, and a tapered sink hole corresponding to the panel. This facilitates panel installation.

[0013] Optionally, a pressure regulating valve is provided between the positive pressure air source and the connector to facilitate air pressure adjustment.

[0014] The beneficial effects of this utility model are:

[0015] This invention features a panel and a guide plate body. The panel has a fan-shaped array of microholes, and the guide plate body has grooves corresponding to the microholes. The panel and guide plate body are sealed together, forming a cavity in the grooves that communicate with the microholes. During operation, compressed air at a certain pressure overflows from the fan-shaped array of microholes on the panel, forming a stable air film layer of a certain thickness between the panel surface and the frame paper. This reduces direct contact friction between the frame paper and the panel surface, eliminates scratches on the frame paper surface, and improves the appearance and packaging quality of the product.

In the description of this utility model, it should be understood that if terms such as "upper", "lower", "left", "right", "front", "rear", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figure, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above-mentioned terms can be understood according to the specific circumstances.

[0024] like Figures 1-5 As shown, this utility model discloses a channel guide plate based on a microporous air cushion, comprising a panel 1 and a guide plate body 2. The panel 1 has a plurality of micropores 11 arranged in a fan-shaped array. The guide plate body 2 has grooves 21 corresponding to the areas of the micropores 11. The panel 1 and the guide plate body 2 are sealed together, so that the grooves 21 form cavities communicating with the micropores 11. It should be noted that this channel guide plate is an improvement upon the original second-section guide plate of the packaging machine; the installation position and operating principle of the improved channel guide plate remain fundamentally unchanged.

[0025] In this embodiment, the guide plate body 2 is provided with a connector 22 communicating with the cavity. The connector 22 can be a common quick-connect connector with a threaded end. The connector 22 is used to communicate with a positive pressure gas source. When positive pressure gas overflows at high speed from the micropores 11, according to Poiseuille's flow equation in fluid mechanics, a stable gas film layer of stable thickness is formed at the contact interface. This gas film layer achieves non-contact suspension between the object and the surface through dynamic pressure balance. In this embodiment, the diameter of the micropores 11 ranges from 0.5 mm to 1 mm, and the reference gas pressure is 0.1-0.4 MPa, resulting in a stable gas film layer of 5-50 μm thickness forming at the contact interface between the panel 1 surface and the frame paper. The positive pressure gas source can utilize existing compressed air sources in the workshop, and a pressure regulating valve is provided between the positive pressure gas source and the connector 22 to adjust the gas pressure and generate a gas film layer within the corresponding range.

[0026] In this embodiment, to avoid the rough panel surface from disrupting the continuity of the air film layer, a self-lubricating coating is applied to the panel 1 surface corresponding to the air film layer. For example, the self-lubricating layer is a polytetrafluoroethylene (PTFE) composite material layer; preferably, a carbon fiber reinforced PTFE composite material (i.e., carbon fiber reinforced PTFE) is selected to form a synergistic lubrication effect with the air film layer.

[0027] In this embodiment, the thickness of panel 1 is 1 / 4 of the thickness of the channel guide plate, and the thickness of guide plate body 2 is 3 / 4 of the thickness of the channel guide plate. A plurality of bosses 23 are provided within the groove 21. One end of each boss 23 abuts against panel 1, and the other end has an internal thread 24. The guide plate body 2 has a plurality of threaded holes 25 on the edge of the groove 21, corresponding to tapered sinkholes 12 on panel 1. The bosses 23 abut against screws to fasten the panel. Simultaneously, sealant is applied between panel 1 and guide plate body 2 to enhance the sealing of the cavity.

[0028] The working principle of this utility model is as follows:

[0029] The channel guide plate of this utility model is installed on the No. 3 wheel and connected to compressed air through the connector 22. During the operation of the equipment, the compressed air overflows from the micro-holes 11 arranged in a fan shape on the panel 1, forming a stable air film layer of a certain thickness between the surface of the panel 1 and the frame paper. This avoids direct contact and friction between the frame paper and the surface of the panel 1, completely eliminates the scratching phenomenon on the surface of the frame paper, and improves the appearance and packaging quality of the product.

[0030] During this process, the boss 23 abuts against the interior of the panel 1, causing the panel 1 to apply a pulling force to the fastening screw, thereby reducing the loosening of the fastening screw. At the same time, sealant is applied between the panel 1 and the guide plate body 2 to enhance the sealing of the cavity.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
