Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production, and more particularly to an automatic anti-blocking device for a tobacco feeder. Background Art

[0002] The tobacco-making workshop uses a wind-driven tobacco feeder to transport the finished tobacco from the tobacco storage cabinet to the various cigarette-making machines in the cigarette-rolling workshop for processing. During the actual production process, the tobacco feeder may experience uneven material on the conveyor belt or excessive speed of the feed roller, which will cause excessive accumulation of material at the bottom of the hopper, resulting in blockage. The tobacco suction tubes will no longer be able to suck in the tobacco smoothly, which will have a significant impact on the production efficiency of the cigarette-rolling workshop.

[0003] Currently, the most common cleaning method is to shut down the wind-powered wire feeder and then manually clean the hopper. However, manual cleaning is time-consuming, difficult, and ineffective. If cleaning is not timely or the air pressure switch detection line becomes clogged during production, it will cause material interruption and machine shutdown, affecting production efficiency.

[0004] Therefore, how to provide an automatic anti-blocking device for a wire feeder has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] One purpose of the utility model is to provide a new technical solution for an automatic anti-blocking device for a wire feeding machine.

[0006] According to a first aspect of the present invention, an automatic anti-blocking device for a wire feeding machine is provided, comprising: a drop hopper, a wire suction pipe and an anti-blocking assembly;

[0007] The top of the drop hopper is located below the belt conveyor and is used to receive tobacco materials conveyed by the belt conveyor. The wire suction tube has a connecting portion, and the connecting portion of the wire suction tube is communicated with the bottom of the drop hopper.

[0008] The anti-blocking material assembly includes two photoelectric switches, a controller, a main nozzle and a side nozzle.

[0027] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0028] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0029] like Figures 1 to 2 As shown, an embodiment of the utility model provides an automatic anti-blocking device for a wire feeding machine, comprising: a drop hopper 1, a wire suction tube 2 and an anti-blocking component 3.

[0030] The top of the hopper 1 is located below the belt conveyor. The hopper 1 is in a frustum shape and is used to receive tobacco materials conveyed by the belt conveyor. The suction tube 2 has a connecting portion 21 , which is connected to the bottom of the hopper 1 .

[0031] The anti-blocking assembly 3 includes two photoelectric switches 31, a controller, a main nozzle 32, and a side nozzle 33. The two photoelectric switches 31 are located on opposite sides of the hopper 1. The controller is electrically connected to the two photoelectric switches 31, the main nozzle 32, and the side nozzle 33. The side nozzle 33 is located at the connection portion 21 of the aspiration tube 2. The main nozzle 32 is located on the aspiration tube 2 and below the side nozzle 33. Both the main nozzle 32 and the side nozzle 33 are connected to an external compressed air pipeline. The photoelectric switch 31 has an indicator light: green indicates no material and yellow indicates material is present. This indicator light is used to detect whether tobacco material is blocked below the hopper 1.

[0032] Specifically, the jet direction of the main nozzle 32 is different from that of the side nozzle 33. The jet direction of the main nozzle 32 is aligned with the radial direction of the aspiration tube 2, while the jet direction of the side nozzle 33 is perpendicular to the radial direction of the aspiration tube 2. The high-pressure airflow ejected by the side nozzle 33 acts on the connection between the aspiration tube 2 and the hopper 1, while the high-pressure airflow ejected by the main nozzle 32 acts on the tobacco material that has fallen into the aspiration tube 2.

[0033] When the drop hopper 1 is not blocked, the photoelectric switch 31 displays a green light. At this time, the controller, the main nozzle 32 and the side nozzle 33 are all out of operation.

[0034] When hopper 1 becomes clogged, photoelectric switch 31 displays a yellow light and transmits a signal to the controller. The controller then activates side nozzle 33, directing high-pressure airflow toward the connection between aspiration tube 2 and hopper 1, thereby clearing the tobacco material clogged there. If photoelectric switch 31 remains yellow for a preset period of time, the controller then activates main nozzle 32, activating both side nozzle 33 and main nozzle 32 simultaneously. These nozzles act on aspiration tube 2, increasing the flow rate of tobacco material within it. This resolves the clogged hopper 1 and allows the tobacco material to be distributed into aspiration tube 2 through negative pressure.

[0035] It should be noted that when the photoelectric switch 31 is yellow for a preset time, the controller then controls the main nozzle 32 to operate. In this embodiment, the preset time is 5 seconds. The preset time can also be larger or smaller, which is not limited here.

[0036] The utility model is achieved by positioning the top of the dropping hopper 1 below the belt conveyor, and connecting the connecting portion 21 of the wire suction tube 2 to the bottom of the dropping hopper 1; two photoelectric switches 31 are respectively arranged on opposite sides of the dropping hopper 1, and the controller is electrically connected to the two photoelectric switches 31, the main nozzle 32 and the side nozzle 33; the side nozzle 33 is arranged at the connecting portion 21 of the wire suction tube 2, the main nozzle 32 is arranged on the wire suction tube 2, and is located below the side nozzle 33, and both the main nozzle 32 and the side nozzle 33 are connected to an external compressed air pipeline. When the drop hopper 1 is not blocked, the photoelectric switch 31 displays a green light; when the drop hopper 1 is blocked, the photoelectric switch 31 displays a yellow light and transmits a signal to the controller. At this time, the controller controls the side nozzle 33 and the main nozzle 32 to work, so that the side nozzle 33 and the main nozzle 32 introduce high-pressure airflow into the suction tube 2, thereby clearing the tobacco material blocked at the connection between the drop hopper 1 and the suction tube 2, and distributing the tobacco material into the suction tube 2 through negative pressure, thereby realizing the supply of tobacco, reducing the labor intensity of on-site operators, ensuring the supply of tobacco in the rolling and packaging workshop, and improving production efficiency.

[0037] In one embodiment of the automatic anti-blocking device for wire feeding machine of the present utility model, as Figure 1 As shown, in order to increase the stability of the connection between the drop hopper 1 and the wire suction tube 2, the wire feeding machine automatic anti-blocking device further includes a flange 4, and the drop hopper 1 and the wire suction tube 2 are fixed by the flange 4.

[0038] In one embodiment of the automatic anti-blocking device for a wire feeding machine of the present invention, an opening (not shown in the figure) is provided on the side wall at the bottom of the hopper 1 .

[0039] The anti-blocking material assembly 3 further includes an observation window 34 , which is disposed in the opening, and the photoelectric switch 31 is located outside the observation window 34 .

[0040] Furthermore, the observation window 34 is made of acrylic glass, which neither blocks the photoelectric switch 31 from transmitting signals nor prevents the photoelectric switch 31 from being stained by dust.

[0041] Specifically, the observation window 34 is fixed at the opening by bolts.

[0042] The utility model provides an opening on the side wall of the bottom of the hopper 1, and sets the observation window 34 in the opening, and the photoelectric switch 31 is located outside the observation window 34, which can facilitate the photoelectric switch 31 to observe the situation inside the hopper 1.

[0043] In one embodiment of the automatic anti-blocking device for wire feeding machine of the present utility model, as Figure 2 As shown, mounting holes (not shown in the figure) are provided on the side wall of the bottom of the hopper 1, and the mounting holes are located on both sides of the opening.

[0044] The anti-blocking component 3 further includes a bracket 35 , both ends of which are connected to the mounting holes. The photoelectric switch 31 is disposed on the bracket 35 , and the bracket 35 is located above the observation window 34 .

[0045] The utility model sets mounting holes on both sides of the opening and connects the two ends of the bracket 35 to the mounting holes. The photoelectric switch 31 is set on the bracket 35, and the bracket 35 is located above the observation window 34, so that the bracket 35 can be stably installed on the hopper 1, effectively ensuring the accuracy of the photoelectric switch 31 in detecting whether the hopper 1 is blocked.

[0046] In one embodiment of the automatic anti-blocking device for a wire feeding machine of the present invention, a waist-shaped hole 36 is provided on the bracket 35, and the photoelectric switch 31 is fixed in the waist-shaped hole 36. The position of the photoelectric switch 31 can be adjusted through the waist-shaped hole 36, so as to facilitate timely adjustment of the shooting angle of the photoelectric switch 31.

The first wire suction branch 22, the second wire suction branch 23 and the third wire suction branch 24 are all vertically connected to the connecting portion 21. The main nozzle 32 is arranged at the connection between the first wire suction branch 22, the second wire suction branch 23 and the third wire suction branch 24 and the connecting portion 21. The jet direction of the main nozzle 32 is the same as the radial direction of the wire suction tube 2.

[0048] Specifically, the first end of the first wire suction branch tube 22, the first end of the second wire suction branch tube 23 and the first end of the third wire suction branch tube 24 are all vertically connected to the connecting portion 21, and the second end of the first wire suction branch tube 22, the second end of the second wire suction branch tube 23 and the second end of the third wire suction branch tube 24 are connected to different cigarette making machines, thereby providing tobacco to different cigarette making machines.
