Description

Technical Field

[0001] The utility model relates to the technical field of filter rod production, in particular to a filter rod accelerating conveying device and a filter rod forming machine. Background Art

[0002] A filter rod forming machine is a rolling and forming device for producing filter rods used in cigarettes. A filter rod refers to a round rod made of specific materials through processing and rolling, which filters certain substances (such as tar, nicotine, etc.) in cigarette smoke and has a certain length. Cigarette tow is one of the main forming materials for producing filter rods.

[0003] The main steps of the filter rod forming process include: first, the cigarette tow is loosened, and then a plasticizer is evenly sprayed; then the treated cigarette tow is wrapped with forming paper and formed and cut according to the specified requirements; finally, the filter rod is conveyed to the downstream machine through an accelerating wheel and a grooved drum. After the filter tip strip is cut into filter tips of a certain length, it needs to be accelerated by the accelerating wheel and thrown into the grooved drum. Since dust such as layer powder of tow and small tow flying flowers will be generated during the process of cutting the filter rod, and these dusts also contain a little plasticizer and are sticky. Although negative pressure suction can suck in part of the dust, due to the stickiness of the dust, the dust is still likely to accumulate inside the accelerating wheel seat after long-term operation and block the path through which the negative pressure passes. When the path through which the negative pressure passes is blocked, the suction force at the negative pressure suction holes on the accelerating wheel decreases, and the filter rod cannot be accelerated and conveyed in place, resulting in the filter rod being unable to enter the grooved drum normally, thus causing flying rods ( "flying rods" refer to the filter rods flying out of the grooved drum), and further causing the production to be unable to proceed normally and the equipment to stop. In order to ensure the normal and stable production of the equipment, the operator has to remove the accelerating wheel and the accelerating wheel seat for cleaning, which increases the extra workload of the operator and reduces the operating efficiency of the equipment. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the inside of the accelerating wheel seat in the existing filter rod accelerating conveying device is not easy to clean. The utility model provides a filter rod accelerating conveying device and a filter rod forming machine, which can facilitate the staff to clean the inside of the accelerating wheel seat by arranging a cleaning hole on one side of the accelerating wheel seat, thereby reducing the workload of the staff and improving the operating efficiency of the equipment.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components.

[0026] To make the objectives, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] As Figure 1 、 Figure 2 and Figure 3 shown, the embodiment of the present utility model provides a filter rod accelerating and conveying device, including: at least one accelerating wheel seat 1, at least one accelerating wheel 2, and a cleaning hole 13.

[0028] At least one accelerating wheel seat 1, which is internally provided with a cavity for the passage of negative pressure. A connecting portion 11 is provided on one side surface of the accelerating wheel seat 1, and the cavity is communicated with the negative pressure channel through the connecting portion 11;

[0029] At least one accelerating wheel 2 is sleeved on the lower end of the accelerating wheel seat 1. A plurality of negative pressure suction holes 21 are provided on the circumferential surface of the accelerating wheel 2. The negative pressure suction holes 21 are used for adsorbing filter rods. The accelerating wheel 2 can rotate along its own central axis, and the accelerating wheel 2 is used for accelerating and conveying the filter rod 3; wherein, an air distribution hole 12 is provided at the lower end of the accelerating wheel seat 1, and the air distribution hole 12 is arranged to be communicated with some of the negative pressure suction holes 21, and the air distribution hole 12 is used for conveying negative pressure to some of the negative pressure suction holes 21;

[0030] The cleaning hole 13 is provided on the side wall of the accelerating wheel seat 1, and a detachable plug 14 is configured on the cleaning hole 13. The cleaning hole 13 is communicated with the connecting portion 11 and the air distribution hole 12 to facilitate cleaning the dust accumulation inside the cavity.

[0031] The applicant fully considered the problems that occurred in cleaning the filter rod accelerating and transporting device in the prior art. By providing a cleaning hole 13 on one side surface of the accelerating wheel seat 1, and then using a plug 14 that matches the cleaning hole 13 to seal the accelerating wheel seat 1, the diameter of the cleaning hole 13 can be designed according to the size of one side surface of the accelerating wheel seat 1, so as to facilitate the operator to clean the dust accumulation inside the accelerating wheel seat 1.

[0032] Specifically, when the filter rod accelerating and conveying device is operating normally, the hole plug is in a state of sealing the cleaning hole. When the "flying rod" situation of the filter rod occurs, the dust accumulation inside the accelerating wheel seat 1 blocks the path through which the negative pressure passes. At this time, the operator releases the blockage of the cleaning hole 13 by the hole plug 14 and uses a cleaning tool (such as a handheld compressed air pipe or other tools) to clean the cavity inside the accelerating wheel seat 1. After the dust accumulation in the cavity is blown into the negative pressure channel, the negative pressure in the negative pressure channel is used to suck out the dust accumulation, completing the cleaning of the cavity of the accelerating wheel seat 1.

[0033] During specific implementation, referring to Figure 2 , the diameter of the air distribution hole 12 is set to be less than 5 mm and greater than the diameter of the negative pressure suction hole 21. By setting the diameter of the air distribution hole 12 to be less than 5 mm and greater than the diameter of the negative pressure suction hole 21, on the premise of ensuring the smooth transmission of the negative pressure to the negative pressure suction hole 21, the leakage of the negative pressure can be reduced, thereby avoiding the weakening of the adsorption force of the negative pressure suction hole 21 on the filter rod 3.

[0034] Furthermore, the cleaning hole 13 is arranged on the side surface of the accelerating wheel seat 1 facing the filter rod 3.

[0035] The filter rod accelerating and conveying device of the present utility model is provided with a cleaning hole 13 on the side surface of the accelerating wheel seat 1 facing the filter rod 3, which is convenient for the operator to clean the dust accumulation inside the accelerating wheel seat 1.

[0036] In some embodiments, the hole plug 14 is connected to the cleaning hole 13 by interference fit.

[0037] In some embodiments, the hole plug 14 is connected to the accelerating wheel seat 1 through a magnetic component.

[0038] In some embodiments, at least one threaded hole is provided on the accelerating wheel seat 1, and the hole plug 14 is threadedly connected to the threaded hole through a bolt.

[0039] During specific implementation, the connection method between the hole plug 14 and the cleaning hole 13 can be selected from any one of interference fit, magnetic attraction, and bolt connection according to actual production needs, ensuring that the hole plug 14 can firmly seal the cleaning hole 13 and facilitating the operator to disassemble the hole plug 14 for cleaning the dust accumulation in the cavity.

[0040] Exemplarily, the material of the accelerating wheel seat 1 is stainless steel. The design of selecting stainless steel as the material of the accelerating wheel seat 1 can ensure the structural strength of the filter rod accelerating and conveying device, making the device not easily damaged.

[0041] Exemplarily, the material of the hole plug 14 is rubber or stainless steel.

[0042] In some embodiments, the material of the hole plug 14 can be selected according to the connection method between the hole plug 14 and the cleaning hole 13 to facilitate the processing and installation of this structure.

[0043] Based on the same inventive concept, an embodiment of the present utility model also discloses a filter rod forming machine, which includes a filter rod accelerating and conveying device provided in any of the above embodiments.

[0044] It should be noted that in the examples and descriptions of the present utility model, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, a statement including a defined element does not exclude the presence of additional identical elements in the process, method, article or device including the element.
