Description

Technical Field

[0001] This utility model relates to the field of cigarette manufacturing technology, and in particular to a rejection device. Background Technology

[0002] To expedite cigarette making, the ZJ17 cigarette making machine is commonly used in existing technologies. However, when the machine is stopped, restarted, or adjusted, residual materials such as the cigarette tipper, tobacco assemblies, and tipping paper in the rolling system can enter the rolling plate area, causing the rolling plate to jam and the machine to stop. To avoid this, the rolling rollers are usually cleaned manually. However, manual cleaning is not only costly and inefficient, but also prone to incomplete cleaning and requires machine shutdown.

[0003] Therefore, there is an urgent need for a rejection device to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a rejection device that can automatically reject auxiliary materials without stopping the machine, thereby reducing labor costs, ensuring cleaning effect, and improving production efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A rejection device, comprising:

[0007] A gas distribution mechanism is set at a preset work station. The gas distribution mechanism includes a gas distribution component and a gas distribution seat. The gas distribution component is connected to a gas distribution connector at the bottom of the gas distribution seat. An air blowing hole is opened on the gas distribution seat, and the gas distribution connector and the air blowing hole are connected through a gas distribution channel.

[0008] The rubbing wheel is coaxially sleeved on the outer periphery of the air distribution seat. The rubbing wheel is configured to rotate around its own axis. The outer periphery of the rubbing wheel is provided with a groove, and the groove is provided with a vent hole that runs radially through it. When the rubbing wheel rotates to the point where the vent hole is directly opposite the blowing hole, the airflow generated by the air distribution assembly can remove the auxiliary material in the groove.

[0009] Preferably, the outer periphery of the cigarette-rubbing wheel is evenly provided with multiple wheel rims, and a wheel groove is formed between two adjacent wheel rims. Each wheel rim is provided with multiple adsorption holes.

[0010] Preferably, the outer periphery of the air distribution seat is provided with at least two groups of air holes, and each group of air holes includes at least two air blowing holes.

[0011] Preferably, at least two of the pore groups are arranged at axial intervals along the gas distribution seat.

[0012] Preferably, the vent hole is provided corresponding to the air blowing hole.

[0013] Preferably, the gas distribution assembly includes a solenoid valve and a gas pipe, the gas pipe connecting the solenoid valve and the gas distribution connector, and the solenoid valve is capable of controlling the flow of gas.

[0014] Preferably, the air tube is a flexible tube, and the air tube is detachably connected to the air distribution connector and the solenoid valve.

[0015] Preferably, the end of the cigarette-rubbing wheel away from the gas distribution assembly is connected to a cover, and a rotating wheel is axially arranged at the center of the gas distribution seat, and the cover is connected to the rotating wheel so that the rotating wheel can drive the cigarette-rubbing wheel to rotate synchronously around the axis.

[0016] Preferably, the cigarette-rubbing wheel is provided with a plurality of locking holes evenly arranged in the circumferential direction, and the locking member can pass through the cover and form a detachable connection with the locking holes;

[0017] The cover has multiple waist holes along the axial direction, and the rotating wheel has multiple fastening holes along the circumferential direction. The locking member can pass through the waist holes and form a detachable connection with the fastening holes.

[0018] Preferably, the cover has a positioning hole at its center, and the end of the rotary wheel opposite to the gas distribution seat has a positioning part, which can be inserted into the positioning hole.

[0019] The beneficial effects of this utility model are:

[0020] This utility model discloses a rejection device. The rejection device includes an air distribution mechanism and a tobacco-rubbing wheel. The air distribution mechanism is set at a preset work position and includes an air distribution component and an air distribution seat. The air distribution component is connected to an air distribution connector at the bottom of the air distribution seat. The air distribution seat has an air blowing hole, and the air distribution connector and the air blowing hole are connected through an air distribution channel. The tobacco-rubbing wheel is coaxially sleeved on the outer periphery of the air distribution seat. The tobacco-rubbing wheel is configured to rotate around its own axis. The outer periphery of the tobacco-rubbing wheel is provided with a wheel groove, and a radially penetrating air hole is provided in the wheel groove. When the tobacco-rubbing wheel rotates to the point where the air hole and the air blowing hole are directly opposite each other, the airflow generated by the air distribution component can reject the auxiliary material in the wheel groove.

[0021] In this device, the air distribution component generates a high-speed airflow, which is then ejected from the air blowing hole after passing through the air distribution connector and air distribution channel. Therefore, when the air blowing hole and the vent hole are aligned, the high-speed airflow can blow the auxiliary material in the wheel groove off. As the rubbing wheel rotates, the wheel grooves on its outer circumference can be aligned with the air blowing hole one by one. This ensures that the auxiliary material in each wheel groove can be automatically removed without stopping the machine, thereby reducing labor costs. It not only ensures the cleaning effect and avoids incomplete removal, but also improves production efficiency. Attached Figure Description

[0033] This embodiment provides a rejection device, such as Figure 1 As shown, the rejection device includes an air distribution mechanism and a rubbing wheel 30. The air distribution mechanism is set at a preset work position and includes an air distribution component 10 and an air distribution seat 20. The air distribution component 10 is connected to an air distribution connector 21 at the bottom of the air distribution seat 20. The air distribution seat 20 has an air blowing hole 22, and the air distribution connector 21 and the air blowing hole 22 are connected through an air distribution channel 23. The rubbing wheel 30 is coaxially sleeved on the outer periphery of the air distribution seat 20. The rubbing wheel 30 is configured to rotate around its own axis. The outer periphery of the rubbing wheel 30 is provided with a wheel groove 31. A radially penetrating air hole 311 is provided in the wheel groove 31. When the rubbing wheel 30 rotates to the point where the air hole 311 is directly opposite the air blowing hole 22, the airflow generated by the air distribution component 10 can reject the auxiliary material in the wheel groove 31.

[0034] In this device, the air distribution component 10 can generate a high-speed airflow, which is then ejected from the air blowing hole 22 after passing through the air distribution connector 21 and the air distribution channel 23. Therefore, when the air blowing hole 22 is aligned with the air vent 311, the high-speed airflow can blow off the auxiliary material in the wheel groove 31. As the rubbing wheel 30 rotates, the wheel groove 31 on its outer circumference can be aligned with the air blowing hole 22 one by one. This ensures that the auxiliary material in each wheel groove 31 can be automatically removed without stopping the machine, thereby reducing labor costs. It not only ensures the cleaning effect and avoids incomplete removal, but also improves production efficiency.

[0035] Specifically, such as Figure 1 As shown, the outer periphery of the cigarette-rolling wheel 30 is evenly distributed with multiple rims 32, and a groove 31 can be formed between any two adjacent rims 32. Each rim 32 is provided with multiple adsorption holes 321. This arrangement not only simplifies the overall structure of the cigarette-rolling wheel 30, but also ensures the uniform distribution of the multiple grooves 31. The multiple adsorption holes 321 can correspondingly adsorb the tipping paper used in the production of cigarettes, and the ventilation holes 311 in the grooves 31 can also correspondingly adsorb the cigarette stick.

[0036] It should be noted that during the cigarette production process, the cigarette rolling wheel 30 is also connected to the negative pressure mechanism. The negative pressure mechanism can generate a negative pressure effect at the air vent 311 and the adsorption hole 321, so that when the cigarette rolling machine is working, the adsorption hole 321 can adsorb the tipping paper and the air vent 311 can adsorb the cigarette stick, thus completing the cigarette rolling process. When the cigarette rolling machine stops, the air distribution component 10 is activated, which can cause a high-speed airflow to be ejected from the air blowing hole 22, thereby quickly forming an outward high-speed airflow at the adsorption hole 321 and the air vent 311, so as to remove residual auxiliary materials such as tipping paper or cigarette stick.

[0037] In addition, such as Figure 1 As shown, the outer periphery of the air distribution seat 20 is provided with at least two air hole groups, and each air hole group includes at least two air blowing holes 22. This arrangement can ensure sufficient airflow intensity, thereby improving the air blowing removal effect, avoiding the situation of auxiliary material residue, and also ensuring that even if one air blowing hole 22 is blocked, the remaining air blowing holes 22 can still blow out high-speed airflow to complete the removal task.

[0038] It is worth noting that in this embodiment, two sets of air holes are provided, and each set includes two air holes 22. One set of air holes is mainly used to remove cigarettes from the wheel groove 31, and the other set is mainly used to remove residual tipping paper from the wheel rim 32, thus ensuring good removal of both cigarettes and tipping paper. In other embodiments, the number of air hole sets and the number of air holes 22 in each set can be adjusted according to actual needs; this embodiment does not impose specific limitations.

[0039] like Figure 1 As shown, at least two sets of air vents are arranged at axial intervals along the air distribution seat 20. This structure can shorten the flow path of high-speed airflow in the air distribution channel 23, thereby greatly reducing energy loss and ensuring good removal efficiency, while also enhancing the aesthetics of the robust structure.

[0040] In addition, such as Figure 1 As shown, the ventilation hole 311 and the blowing hole 22 are correspondingly arranged. This arrangement not only ensures that the negative pressure mechanism can form a strong negative pressure effect at the ventilation hole 311, ensuring the smooth operation of cigarette making, but also ensures that the high-pressure airflow blown out of the blowing hole 22 can quickly enter the ventilation hole 311 during the removal process, ensuring good removal efficiency.

[0041] like Figure 1As shown, the gas distribution assembly 10 includes a solenoid valve 11 and an air pipe 12. The air pipe 12 connects the solenoid valve 11 to the gas distribution connector 21. The solenoid valve 11 can control the flow of air. This configuration further simplifies the overall structure and improves the ease of installation. Simultaneously, the solenoid valve 11 can communicate with the PLC control system to precisely control the flow of high-pressure gas. That is, after the PLC control system issues a rejection command, the solenoid valve 11 is triggered synchronously. The high-pressure airflow enters the gas distribution connector 21 through the air pipe 12 and is ejected from the blowing hole 22 after passing through the gas distribution channel 23. This creates an outward thrust at the vent hole 311 or adsorption hole 321, rejecting the auxiliary materials from the cigarette rolling wheel 30. After the rejection is completed (approximately three to five seconds), the solenoid valve 11 closes, the airflow is cut off, and the subsequent cigarette-making process is not affected.

[0042] It should be noted that in this embodiment, the air pipe 12 is a flexible pipe, and the air pipe 12, the air distribution connector 21, and the solenoid valve 11 are all detachably connected. The flexible pipe can improve the flexibility of installation or connection; the detachable connection method can further improve the convenience of subsequent component maintenance and also facilitate the unblocking of the entire air distribution pipeline.

[0043] In addition, such as Figure 1 As shown, the end of the tobacco-rubbing wheel 30 furthest from the air distribution assembly 10 is connected to a cover 40. A rotating wheel 24 is axially positioned at the center of the air distribution seat 20, and the cover 40 is connected to the rotating wheel 24 so that the rotating wheel 24 can drive the tobacco-rubbing wheel 30 to rotate synchronously around its axis. During the removal process, the air distribution seat 20 remains stationary at a preset position, but its rotating wheel 24 can rotate around its axis, simultaneously driving the cover 40 to rotate around its axis. Since the cover 40 is connected to the tobacco-rubbing wheel 30, this achieves the rotation of the tobacco-rubbing wheel 30 around the air distribution seat 20. The structure is simple, installation is convenient, and it can completely remove auxiliary materials from the outer periphery of the tobacco-rubbing wheel 30.

[0044] Specifically, such as Figure 1As shown, the cigarette-rubbing wheel 30 has multiple locking holes 33 evenly arranged circumferentially, and the locking element 50 can pass through the cover 40 and form a detachable connection with the locking holes 33. The cover 40 has multiple waist holes 41 arranged axially circumferentially, and the rotating wheel 24 has multiple fastening holes 241 arranged circumferentially, and the locking element 50 can pass through the waist holes 41 and form a detachable connection with the fastening holes 241. This arrangement not only ensures the stability of the connection between the cover 40 and the cigarette-rubbing wheel 30, but the evenly arranged circumferential structure of the locking holes 33 also ensures the uniformity of force on the cigarette-rubbing wheel 30. Similarly, the connection method between the rotating wheel 24 and the cover 40 also ensures the stability of the connection and the uniformity of force. In addition, the detachable connection method can improve the convenience of subsequent maintenance and facilitate the replacement of subsequent parts. The waist holes 41 on the cover 40 can provide room for the connection of the locking element 50 and can realize the fine adjustment of the angle and position during the installation process, thereby further improving the convenience of installation.

[0045] It should be noted that in this embodiment, the locking component 50 is a bolt. Bolts are not only simple in structure but also inexpensive, which can reduce manufacturing costs and improve the ease of assembly and disassembly. In other embodiments, screws, locating pins, or other structures may also be used; this embodiment does not impose any specific limitations.

[0046] In addition, such as Figure 1 As shown, a positioning hole 42 is provided in the center of the cover 40, and a positioning part 242 is provided at the end of the rotating wheel 24 away from the air distribution seat 20. The positioning part 242 can be inserted into the positioning hole 42. This arrangement can perform preliminary positioning before installing the cover 40, thereby ensuring the convenience, efficiency and accuracy of installation.

[0047] Referring to the accompanying drawings, the workflow of the rejection device in this embodiment is described as follows:

[0048] First, the PLC control system issues a rejection command, the solenoid valve 11 opens, and the high-speed airflow passes through the air pipe 12, the air distribution connector 21, and the air distribution channel 23 in sequence to reach the air blowing hole 22.

[0049] Secondly, the rubbing wheel 30 rotates around the axis, so that the air vent 311, the adsorption hole 321 and the blowing hole 22 are aligned in sequence.

[0050] Finally, the high-speed airflow is ejected sequentially from the vent 311 and the adsorption hole 321, thereby removing the residual auxiliary materials on the outer periphery of the rubbing wheel 30 one by one.

[0051] In summary, the rejection device in this embodiment can automatically reject auxiliary materials without stopping the machine, thereby reducing labor costs, ensuring cleaning effect, and improving production efficiency.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
