Description

Technical Field

[0001] The present invention belongs to the technical field of cigarette production equipment, and particularly relates to a glass tube replacement structure for a filter rod visual inspection device. Background Art

[0002] To monitor the quality of the visible cavity particulate filter rod in cigarettes, a visual information acquisition device can be used to collect the surface visual information for analysis and judgment. As an alternative solution, a glass tube can be used to connect the production channels of cigarette production equipment and other equipment as a visual inspection channel, which is convenient for collecting visual information while ensuring the sealing performance. However, due to the long-term friction and collision between the filter rod and the inner wall of the glass tube during the production process, the inner wall of the glass tube will inevitably be damaged and soiled. This will not only directly affect the quality of cigarettes but also cause the inability to effectively collect visual information. Therefore, it is necessary to regularly maintain or replace the glass tube. Summary of the Invention

Detailed implementation manner

[0023] The present invention will be described in detail below in conjunction with specific embodiments.

[0024] The utility model relates to a glass tube replacement structure for a filter rod visual inspection device, which is mainly used to assist in replacing and updating the internal glass tube in the filter rod visual inspection device to ensure that the internal glass tube can be cleaned and maintained. Its main feature is to adopt a scheme of inclined-side assembly and support, and use the device to realize side installation. While solving the problem that the existing installation operation space is limited and cannot be operated, the device itself is used as a support and fixing structure for the internal glass tube, further improving the stability of the original device structure.

[0025] As Figure 1 shown, it is a schematic structural diagram of the glass tube replacement structure of the filter rod visual inspection device of the present invention, which mainly includes a positioning guide pipe 2, a sliding support frame 3, and a support plate 4;

[0026] Among them, the support plate 4 is fixed on the cigarette production equipment and is mainly used as the main support structure. In actual implementation, it is formed by being separately provided or modifying the original support structure. The support plate 4 is provided with a replacement channel 4a extending along an arc path; the replacement channel is used to form a channel for the glass tube and other structures to enter and exit the inside of the filter rod visual inspection device. It is easy to know that its basic form is a channel structure with a strip-shaped cross-section. During use, this channel needs to be used to take out or put in the glass tube. Because it involves multiple operations, to ensure the structural stability, the replacement channel 4a should have sufficient depth. For this reason, strengthening portions 4b are provided on both sides of the replacement channel 4a around the inner side of the support plate 4, and a channel extension structure is formed by the strengthening portions to ensure sufficient depth.

[0027] The sliding support frame 3 is used for glass tube replacement operations and also supports and positions the glass tube after replacement. Its main structure includes a push plate 30 and two arc-shaped connecting arms 31; the front ends of the two connecting arms 31 are inserted into the replacement channel 4a, and the rear ends are connected by the push plate 30; to facilitate the assembly and fixing of the guide pipe, a clamping port for clamping the guide pipe 2 is provided at the front end of the connecting arm 31;

[0028] By pushing the push plate 30 to move, the connecting arm can be driven to slide along the replacement channel 4a, and the glass tube guide pipe fixed on the connecting arm can be taken out or sent back.

[0029] As a preferred solution, in order to reduce the overall quality of the replacement device, in this embodiment, the connecting arm 31 adopts a lightweight plate frame structure, such as a lightweight alloy bracket or a plastic bracket. To ensure the tightness of the internal structure and prevent debris from entering the visual acquisition space, when the connecting arm 31 slides to the extreme position, the push plate 30 should be able to cover the replacement channel 4a. In actual implementation, it is controlled by changing the connection angle between the push plate and the connecting arm and controlling the size of the push plate.

[0030] Among them, the material guiding pipe 2 includes a transparent glass pipe 20 in the middle and a support pipe 21 sleeved outside the glass pipe 20. Clamping block parts 210 that can be clamped into the clamping openings are arranged at both ends of the support pipe 21;

[0031] The clamping opening can be used to conveniently fix and disassemble the material guiding pipe. The assembly method between the clamping opening and the material guiding pipe can adopt a movable clamping block snap connection;

[0032] According to needs, a detachable screw connection method can also be adopted to improve the connection strength. Specifically, the clamping block part 210 extends towards the clamping opening side to form a connecting part, and a fixing hole 21a is arranged on the connecting part; a connecting groove that can be docked with the connecting part is correspondingly arranged on the clamping opening, and a screw hole is arranged on the connecting groove opposite to the fixing hole, and the two are connected by a bolt.

[0033] The light-transmitting property of the glass pipe facilitates the smooth progress of visual information acquisition. At the same time, the surface of the glass pipe is smooth and easy to control the size and shape, and it is more suitable for being used as a filter rod transfer channel. The external support pipe can improve the strength of the material guiding pipe on the one hand and protect the internal glass pipe structure on the other hand. It can also block or expose the corresponding area of the glass pipe according to needs to meet the visual information required by the acquisition device at different positions, and at the same time block the light information from other acquisition components, reduce the mutual interference between the acquisition components, and improve the recognizability.

[0034] During specific operation, the two connecting arms 31 slide along an arc path under the limitation of the replacement channel 4a and drive the material guiding pipe 2. When sliding to the extreme position, the glass pipe 20 is aligned with the outlet of the cigarette production equipment to facilitate the smooth picking up of filter rods.

[0035] To ensure that the material guiding pipe can be stably positioned after installation and ensure that the filter rods can smoothly enter and exit the production line along the material guiding pipe, the present invention further includes a guiding block 1. An arc-shaped guiding groove 1a that matches the sliding path of the connecting arm 31 is arranged on the guiding block; a positioning hole 1b is arranged at the bottom of the end of the arc-shaped guiding groove 1a. When the glass pipe 20 moves forward to the extreme position, the positioning hole 1b, the glass pipe 20 and the outlet of the cigarette production equipment are aligned and communicated.

[0036] On the one hand, as a support structure, the guiding block maintains the position of the material guiding pipe after it is in place, ensuring the continuous progress of production. On the other hand, during the movement of the material guiding pipe, it serves as a guiding and positioning reference, assisting the material guiding pipe to quickly and smoothly reach the target position, preventing its deviation, which is conducive to improving the replacement efficiency and ensuring effectiveness.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
