Description

Technical Field

[0001] This utility model relates to the field of flue gas collector treatment technology, specifically to an automatic sealing device for a flue gas collector. Background Technology

[0002] With the deepening of research on smoking and health, people are paying increasing attention to how to efficiently detect and collect cigarette smoke. During combustion, cigarettes produce a large amount of mainstream and sidestream smoke, containing many substances such as tar, nicotine, and carbon monoxide, which not only harm smokers but also cause air pollution. Currently, smoking machines are commonly used in the tobacco industry for detecting mainstream smoke. Rotary smoking machines are primarily used to draw cigarettes, and the content of tar, nicotine, and carbon monoxide in cigarette products is determined by detecting the mainstream smoke. Throughout the entire smoking process of the rotary smoking machine, the smoke collector is a crucial module for capturing total particulate matter from cigarettes. It is a device that collects cigarette sample smoke according to the requirements for determining smoke composition.

[0003] Currently, the operation of laboratory flue gas traps in the process of entering and exiting the fume extraction machine suffers from significant efficiency bottlenecks. After the flue gas is collected, it needs to be sealed and stored. The sealing process currently relies primarily on manual operation to handle the ten flue gas traps that operate sequentially on the fume extraction machine. This operational efficiency is mismatched with the equipment's capacity, resulting in wasted manpower and time. These problems collectively reflect the systemic deficiencies in the current flue gas trap operation process. Utility Model Content

[0004] The technical problem to be solved by this utility model is: how to provide a device that can automatically seal a flue gas collector to improve sealing efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An automatic sealing device for a flue gas collector includes a base plate, a cap plate assembly, a linear cylinder, and a flue gas collector mounting block located above the base plate. The output end of the linear cylinder is connected to the flue gas collector mounting block. The cap plate assembly is located outside the flue gas collector mounting block. The linear cylinder can push the flue gas collector on the flue gas collector mounting block to the cap plate assembly for sealing.

[0007] This application utilizes a linear cylinder to push the flue gas collector mounting block, which is installed in the flue gas collector, into the cap plate assembly for sealing, thereby achieving automated sealing. It can quickly and continuously seal several flue gas collectors, improving sealing efficiency, and the integrated disc design saves space.

[0008] As a further embodiment of this utility model: the cap plate assembly includes two sets of symmetrically arranged turntables connected by a central axis; one set of turntables is connected to a drive mechanism, and the other set of turntables is equipped with a photoelectric positioning mechanism.

[0009] As a further embodiment of this utility model: several cap grooves are evenly distributed around the circumference of the two sets of turntables, and caps are installed in the cap grooves; the center of the two sets of turntables is connected to the support through bearings, and the bottom of the support is mounted on the base plate.

[0010] As a further embodiment of this utility model: a bracket is provided on the base plate and on the outside of the turntable, and a pushing block is provided on the top of the bracket facing the cap groove, the position of the pushing block corresponding to the position of the cap groove.

[0011] As a further embodiment of this utility model: a pushing cylinder is provided on the top side of the bracket facing away from the cap groove, and the pushing cylinder is connected to the pushing block.

[0012] As a further embodiment of this utility model: the photoelectric positioning mechanism includes a positioning disc installed on the central axis of another set of turntables. Several sets of slots corresponding to the cap slots are equally spaced on the positioning disc. A photoelectric switch is provided on the outer side of the positioning disc. The photoelectric switch is connected to the corresponding support through a switch base.

[0013] As a further embodiment of this invention, the number of slots is the same as the number of cap slots on a single turntable.

[0014] As a further embodiment of this utility model: the driving mechanism includes a stepper motor located at the bottom of the base plate, the output end of the stepper motor is connected to a lower synchronous pulley, and the central shaft of one of the turntables is connected to an upper synchronous pulley, wherein the upper synchronous pulley and the lower synchronous pulley are connected by a synchronous belt drive.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] First, the sealing device of this application is equipped with two sets of symmetrical turntables, and several caps are installed on the turntables. When the linear cylinder pushes the flue gas collector between the two sets of turntables, the caps can be aligned with the flue gas collector by rotating the turntables and then moved onto the flue gas collector by using the push block. With the above configuration, multiple flue gas collectors can be sealed continuously in a fast manner, improving sealing efficiency, and the disc design saves space.

[0017] Secondly, a positioning disc is set on one side of the turntable, and a slot corresponding to the cap is set on the positioning disc. The photoelectric switch is located on the outside of the positioning disc. When the positioning disc rotates to the point where the slot corresponds exactly to the photoelectric switch, the cap rotates to the point where it corresponds to the center of the flue gas collector. The photoelectric switch is used to accurately determine the rotation position of the cap to ensure that it can move accurately onto the flue gas collector. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 and Figure 2 An automatic sealing device for a smoke collector is used in the subsequent clamping and sealing of a smoke collector after it is discharged from a smoke extraction machine. The sealing device 4 includes a base plate 41 and a linear cylinder 42 and a smoke collector mounting block 43 mounted on the base plate 41. The smoke collector mounting block 43 is mounted on the output end of the linear cylinder 42, and the linear cylinder 42 can drive the smoke collector mounting block 43 to move. The linear cylinder 42 is detachably mounted on the base plate 41 by bolts or pins.

[0024] Furthermore, two sets of symmetrically arranged circular turntables 49 are installed on the top of the base plate 41 and in front of the flue gas collector mounting block 43. The central axes of the two sets of turntables 49 are connected, enabling synchronous rotation. Each set of turntables 49 has several cap slots evenly distributed around its circumference, and caps 48 are installed in the cap slots. Multiple flue gas collectors can be sealed continuously. The number of cap slots and caps 48 is the same, and this application does not limit this.

[0025] Reference Figure 1 and Figure 2 Both sets of turntables 49 are connected to the support 410 via bearings on the outer side of their central shafts. The bottom of the support 410 is detachably mounted on the base plate 41 via bolts or pins. The central shaft of one of the turntables 49 passes through the corresponding support 410 and is connected to an upper synchronous pulley 411. A stepper motor 414 is mounted on the bottom of the base plate 41, and the output end of the stepper motor 414 is connected to a lower synchronous pulley 413. The upper synchronous pulley 411 and the lower synchronous pulley 413 are connected by a synchronous belt 412. Therefore, by controlling the stepper motor 414 to work, the upper synchronous pulley 411 and the lower synchronous pulley 413 can be driven to rotate synchronously, thereby driving the two coaxial turntables 49 to rotate synchronously, thus adjusting the position of the cap 48.

[0026] A bracket 44 is provided on the base plate 41 and on the outer side of the front end of the flue gas collector mounting block 43 near the turntables 49 on both sides. A push block 46 is provided on the top of the bracket 44 facing the cap groove, and a push cylinder 45 is provided on the top of the bracket 44 facing away from the cap groove. The push cylinder 45 is connected to the push block 46. The push cylinder 45 can drive the push block 46 to move toward the position of the cap groove and push the cap in the cap groove to lock onto the flue gas collector, thereby achieving the sealing of the flue gas collector. The longitudinal and lateral positions of the push block 46 correspond to the positions of the cap grooves. By rotating the turntable 49, the cap grooves on it can be driven to align with the push block 46 in sequence, so that all the caps 48 can be moved by the push block 46.

[0027] Reference Figure 2A positioning disc 415 is mounted on a support 410 of another turntable 49. The positioning disc 415 is connected to the central axis of the turntable 49. The size of the positioning disc 415 is smaller than that of the turntable 49. Several sets of slots 416 corresponding to the cap slots are evenly spaced on the positioning disc 415. The number of slots 416 is the same as the number of cap slots on a single turntable 49. A photoelectric switch 417 is provided on the outside of the positioning disc 415. The photoelectric switch 417 is connected to the corresponding support 410 through a switch base 418. When the turntable 49 rotates, it can synchronously drive the positioning disc. When the positioning disc 415 rotates, the slot 416 on the positioning disc 415 moves to the position of the photoelectric switch 417. At this time, the caps 48 on the two turntables 49 are exactly located at the cap installation positions on both sides of the flue gas collector. After the photoelectric switch 417 detects the position of the slot 416, it notifies the stepper motor 414 to stop rotating and perform the corresponding cap sealing. All subsequent cap positions are determined by the positioning between the photoelectric switch 417 and the slot 416. In order to ensure the accuracy of the cap rotation position, it is necessary to ensure that the angle between two adjacent slots 416 is the same as the angle between two adjacent cap slots.

[0028] The specific operating principle of this application is as follows:

[0029] A robotic arm is used to grip the flue gas collector and place it onto the flue gas collector mounting block 43 inside the sealing device 4. Then, a linear cylinder 42 pushes the flue gas collector mounting block 43 to move it between two turntables 49. At this time, the cap openings on both sides of the flue gas collector are aligned with the cap slots on the turntables 49. Subsequently, a stepper motor 414 drives the two turntables 49 to rotate. When the slot 416 on the positioning disc 415 moves to the position of the photoelectric switch 417, the caps 48 on the two turntables 49 are located at the cap mounting positions on both sides of the flue gas collector. After the photoelectric switch 417 detects the position of the slot 416, it notifies the stepper motor 414 to stop rotating and perform the corresponding cap sealing. All subsequent cap positions are determined by the positioning between the photoelectric switch 417 and the slot 416.

[0030] Once the cover is sealed, the robotic arm picks up the flue gas collector from the flue gas collector mounting block 43 and transfers it to the flue gas collector storage rack for storage and retrieval.

[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 the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
