[0025] like Figure 1 As shown, the cleaning device for the photoelectric tube facing area on the feeder provided in this embodiment includes: two cross bars 15, which are respectively arranged at the upper and lower ends of the organic glass plate 2 on the feeder 3, and an organic rod 9 is arranged in the vertical direction between the two cross bars 15, and a sweeping piece 6 is provided on the machine rod 9, and the sweeping piece 6 is in contact with the organic glass plate 2, and a photoelectric tube 1 is provided on the organic glass plate 2. A guide wheel 12 is respectively provided on the two cross bars 15, and each guide wheel 12 can slide along the corresponding cross bar 15, thereby driving the machine rod 9 and the sweeping piece 6 to slide, and a first compressed air duct 13 is respectively provided on the left side of the guide wheel 12 on the two cross bars 15, and a second compressed air duct 14 is respectively provided on the right side of the guide wheel 12 on the two cross bars 15, the first compressed air duct 13 and the second compressed air duct 14 are used to pass compressed air, and the sweeping piece 6 is used to clean the facing area corresponding to the photoelectric tube 1 on the organic glass plate 2.

[0026] The distance between the device and the plexiglass plate 2 is smaller than the distance between the photoelectric tube 1 and the plexiglass plate 2, so the device's left-right movement does not affect the fixed photoelectric tube 1. The plexiglass plate 2 is rectangular in shape, and the bottom of the feeder 3 is equipped with four support columns (not shown). The guide wheel 12 is made of high-strength, wear-resistant, and stain-resistant material, and the two cross bars 15 are made of 304 stainless steel. The dimensions of the guide wheel 12 match the dimensions of the cross bars 15. In one embodiment of the utility model, the cross bars 15 are cylindrical to facilitate the left-right reciprocating motion of the guide wheel 12 thereon.

[0027] In one embodiment of the present invention, there are two cleaning devices for the photoelectric tube illumination area on the feeder, which are respectively arranged on the inner wall and the outer wall of the organic glass plate 2 .

[0028] Furthermore, the shape of the machine rod 9 is a hollow cylinder, and a plurality of vent holes 10 are provided on the machine rod 9. In this way, a portion of the compressed air entering the first compressed air conduit 13 and the second compressed air conduit 14 will pass through the vent holes 10, so that the compressed air is ejected out of the vent holes 10 while providing power, thereby assisting in cleaning the organic glass plate 2 being cleaned, so as to achieve the purpose of better removing tobacco dust and debris. Among them, the machine rod 9 is made of 304 stainless steel, and the upper and lower ends of the machine rod 9 are connected to the guide wheel 12, which is driven by the guide wheel 12 to reciprocate on the upper and lower cross bars 15. It should be noted that the present invention does not specifically limit the number and distribution of the vent holes 10.

[0029] Furthermore, the sweeping blade 6 is made of silicone rubber. It should be noted that the present invention does not impose any specific restrictions on the material of the sweeping blade 6. In other embodiments of the present invention, the sweeping blade 6 can be made of highly elastic, wear-resistant, corrosion-resistant, and heat-resistant rubber. The sweeping blade 6 is perpendicular to the ground and powered by compressed air provided by the first and second compressed air conduits 13 and 14. The random rod 9 reciprocates horizontally, thereby cleaning the organic glass plate 2 and, consequently, the area facing the photoelectric tube 1.

[0030] Furthermore, a bracket 5 is provided on the organic glass plate 2 along the horizontal direction, and the photoelectric tube 1 is fixed on the bracket 5 .

[0031] Furthermore, fixed clips 7 are provided on the left and right sides of the sweeping piece 6, and the fixed clips 7 are connected to the sweeping piece 6 by bolts 8. The fixed clips 7 are welded to the machine rod 9, and the fixed clips 7 are made of stainless steel. In some embodiments of the present invention, the fixed clips 7 are made of 304 stainless steel. 304 steel is a versatile stainless steel material with better rust resistance than 200 series stainless steel. It is also relatively good in high temperature resistance. The general operating temperature limit is less than 650°C, and it has excellent stainless corrosion resistance and good intergranular corrosion resistance. In one embodiment of the present invention, the sweeping piece 6 is shaped like a thin rectangular parallelepiped, with two threaded holes at both ends, which makes it convenient to fix and replace the sweeping piece 6 using the fixed clips 7. Correspondingly, two threaded holes are also provided at the corresponding positions of the two fixed clips 7, which makes it convenient to fix the sweeping piece 6 by bolts 8.

[0032] Furthermore, the cleaning device for the area opposite the photoelectric tube on the feeder also includes a controller, which is respectively connected to the first compressed air conduit 13, the second compressed air conduit 14, and the photoelectric tube 1. The controller comprises a programmable logic controller (PLC) and has a built-in time delay relay. The power supply for the cleaning device for the area opposite the photoelectric tube on the feeder of the present invention is derived from the electrical control cabinet of the process section, and the first compressed air conduit 13 and the second compressed air conduit 14 are ventilated using on-site compressed air. Therefore, when the workshop is operating normally, the required operating conditions for the device are met, eliminating the need for additional operations and increasing the workload of on-site operators. During production, the device detects two input quantities of compressed air and power supply through a controller and automatically enters a working state. When production is completed, the device turns off the power supply and gas source, and automatically stops working by detecting the shutdown of the power and gas sources. The device first cleans the organic glass plate 2, i.e., the shooting area of the photoelectric tube 1, thereby greatly reducing the probability of false signals from the photoelectric tube 1 due to tobacco debris in the shooting area, and greatly reducing the risk of quality accidents such as shutdown and material interruption due to false signals; secondly, it can clean the organic glass plate 2 more effectively and keep the organic glass plate 2 clean without using water, thereby keeping the organic glass plate clean and facilitating the operator to observe the material condition in the feeder more clearly, thus ensuring efficient work and extending the service life of the organic glass plate 2.

[0033] Furthermore, a left limit switch 11 is provided on the left side of the machine rod 9, and a right limit switch 16 is provided on the right side of the machine rod 9. The left limit switch 11 and the right limit switch 16 are respectively connected to the time delay relay in the controller.

[0034] Furthermore, a left limit switch contact seat 17 is provided on the left side of the organic glass plate 2, and a right limit switch contact seat 18 is provided on the right side of the organic glass plate 2, wherein the left limit switch contact seat 17 corresponds to the position of the left limit switch 11, and the contact head of the left limit switch 11 can contact the left limit switch contact seat 17; the right limit switch contact seat 18 corresponds to the position of the right limit switch 16, and the contact head of the right limit switch 16 can contact the right limit switch contact seat 18. During operation, when the device moves to the right to the extreme position, the contact head of the right limit switch 16 on the machine rod 9 is connected to the right limit switch contact seat 18 on the organic glass plate 2, and the signal is transmitted to the controller. At this time, the first compressed air duct 13 on the left is turned off. After the delay relay delays for a certain period of time, the controller connects the second compressed air duct 14 on the right, so that the device moves to the left. When the device moves to the left to the extreme position, the contact head of the left limit switch 11 on the machine rod 9 is connected to the left limit switch contact seat 17 on the organic glass plate 2, and the signal is transmitted to the controller. At this time, the second compressed air duct 14 on the right is turned off. After the delay relay delays for a certain period of time, the controller connects the first compressed air duct 13 on the left, so that the device moves to the right.

[0035] During operation, when production starts normally, the on-site air source and power supply are in a connected state, and the first compressed air conduit 13 and the second compressed air conduit 14 are connected from the air source of the on-site equipment. During production, the air source of the on-site equipment is in a connected state, and the first compressed air conduit 13 and the second compressed air conduit 14 are also ventilated. After production is completed, the air source of the on-site equipment is in a closed state, and the first compressed air conduit 13 and the second compressed air conduit 14 are also cut off. This ensures that the device automatically connects to the air source to provide a power source for the guide wheel 12 after production starts normally, and automatically cuts off the air after production is completed, which does not increase the labor intensity of the on-site operators; the sweeping piece 6 is powered by the compressed air provided by the first compressed air conduit 13 and the second compressed air conduit 14, and the random rod 9 moves back and forth in the horizontal direction, thereby cleaning the organic glass plate 2, that is, cleaning the corresponding area of the photoelectric tube 1.

[0036] Furthermore, the photoelectric tube 1, the left limit switch 11 and the right limit switch 16 are connected to the input end of the controller, and the two first pressurized air tubes 13 and the two second pressurized air tubes 14 are connected to the output end of the controller. The controller is used to issue control instructions to the two first pressurized air tubes 13 and the two second pressurized air tubes 14 according to the status signals of the photoelectric tube 1, the left limit switch 11 and the right limit switch 16, so as to switch the on and off states of the two first pressurized air tubes 13 and the two second pressurized air tubes 14.

[0037] Specifically, if Figure 2As shown, the left limit switch 11 is specifically used to send a left limit signal to the delay relay when it contacts the left limit switch contact seat 17;

[0038] The right limit switch 16 is specifically used to send a right limit signal to the delay relay when it contacts the right limit switch contact seat 18;

[0039] The delay relay is used to: receive the left limit signal of the left limit switch 11 or the right limit signal of the right limit switch 16, and after delay processing, send a switching signal to the controller;

[0040] The photoelectric tube 1 is specifically used to: send a signal to the controller that there is material when the photoelectric tube is not emitting light;

[0041] The controller is specifically used to: after receiving the material signal from the photoelectric tube 1 and the switching signal from the delay relay, cut off the two first compressed air conduits 13 and connect the two second compressed air conduits 14, or cut off the two second compressed air conduits 14 and connect the two first compressed air conduits 13.

[0042] To sum up, the time delay relay and the controller are used to receive the signals sent by the two limit switches, the left limit switch 11 and the right limit switch 16. After the time delay relay receives the limit switch signal, it delays for a period of time and transmits the signal to the controller. The time delay relay is used to reduce the cleaning frequency of the device so that it is within a reasonable range. After receiving the signal from the time delay relay, the controller sends a signal to alternately cut off and connect the first pressurized air duct 13 and the second pressurized air duct 14 at the left and right ends, respectively, so that the device can reciprocate left and right. In addition, the controller needs to simultaneously receive signals from the normal operation of the photoelectric tube 1. When the photoelectric tube 1 is normally connected, it means that the material is out of stock. At this time, the controller will not send a command signal to connect the first compressed air conduit 13 and the second compressed air conduit 14, and the device will not move, which will not affect the normal operation of the photoelectric tube 1. Only when the photoelectric tube 1 is not connected, it means that there is material here, and at the same time, when the two conditions of receiving the signal from the delay relay are met, the controller will send a signal to respectively shut down or connect the two sets of compressed air pipes, the first compressed air conduit 13 and the second compressed air conduit 14, to make the device work, so that the device does not affect the normal operation of the photoelectric tube 1.

[0043] In the specific implementation, the delay relay, left limit switch 11 and right limit switch 16 used in the device are connected in series with the photoelectric tube control circuit of the on-site feeder. After the equipment starts production normally, this circuit is powered on and works normally. After the production is completed, when the equipment is powered off, the device is automatically powered off. This ensures that the device matches the on-site control and enters the working state and stops at the same time as the on-site equipment. Figure 1For example, the arrow indicates the process of the device moving to the right. When the two groups of first compressed air ducts 13 are ventilated, the guide wheel 12 is provided with a thrust to move to the right, driving the machine rod 9 to move to the right. In this process, the sweeping piece 6 is close to the organic glass plate 2 and completes a sweep to the right. At the same time, a part of the compressed air passes through the hollow machine rod 9 and is ejected from the vent 10 to blow the area where the machine rod 9 moves, so as to assist the sweeping piece 6 to better clean the organic glass plate 2. When the device moves to the rightmost end, the right limit switch 16 on the lever 9 is connected to the right limit switch contact 18, and the right limit switch 16 sends a signal to the delay relay. The delay relay transmits the signal to the controller after a delay process. The controller issues an instruction to cut off the compressed air in the upper and lower sets of first compressed air ducts 13 on the left side and connect the upper and lower sets of second compressed air ducts 14 on the right side, providing a thrust to the guide wheel 12 to move leftward, causing the device to move leftward. The process is the same as the rightward movement, completing a cleaning cycle. This reciprocating process systematically cleans the inside and outside of the organic glass plate 1. The distance between the device and the organic glass plate 2 is less than the distance between the photoelectric tube 1 and the organic glass plate 2, so the device will not affect the fixed photoelectric tube 1 during the left and right movement.

[0044] The working principle of the photoelectric tube 1 is that when the photoelectric tube 1 is connected to the opposite direction, it means that there is no material at this location. The motor starts to drive the roller, and the roller drives the belt to move forward, so that the material is transported forward. When the material is transported forward and blocks the photoelectric tube, the signal emitted by the photoelectric tube 1 is blocked by the material and cannot be transmitted. Therefore, in order to prevent the photoelectric tube from judging the material situation during the left and right reciprocating movement of the device from causing false signals, the controller needs to receive the normal working signal of the photoelectric tube 1 at the same time. When the photoelectric tube 1 is normally connected to the opposite direction, it means that there is no material at this location. At this time, the controller will not send a signal to connect the first compressed air conduit 13 and the second compressed air conduit 14, and the device will not move and will not affect the normal operation of the photoelectric tube 1. Only when the photoelectric tube 1 is not connected, it means that there is material at this location. At the same time, when the two conditions of receiving the signal from the delay relay are met, the controller will send a signal to respectively shut down or connect the left and right compressed air pipes of the first compressed air conduit 13 or the second compressed air conduit 14 to make the device work, so that the device does not affect the normal operation of the photoelectric tube 1.

[0045] The utility model connects the on-site compressed air through two first compressed air pipes 13 and two second compressed air pipes 14, and is equipped with a controller, two limit switches, a left limit switch 11 and a right limit switch 16, and a time delay relay to control the on-off time and direction of the compressed air.

[0046] The embodiment of the utility model provides a cleaning device for the photoelectric tube facing area on the feeder, and the sweeping piece is powered by the compressed air provided by the first compressed air duct and the second compressed air duct, and the random rod moves back and forth in the horizontal direction, thereby cleaning the organic glass plate, that is, cleaning the facing area of the photoelectric tube, greatly reducing the probability of false signals of the photoelectric tube caused by tobacco dust blocking the organic glass plate, effectively solving the problem of false detection of photoelectric tube blocking, and improving production continuity, stability and uniformity; the cooperation of the sweeping piece and the machine rod greatly improves the cleaning ability of tobacco dust and debris on the organic glass plate, and truly solves the problem of misjudgment of the photoelectric tube due to tobacco dust and debris from the source; by cleaning the organic glass plate, the labor intensity of on-site operators is reduced, the labor efficiency is improved, and the service life of the organic glass plate is extended through reasonable automatic cleaning; by cutting off and connecting the two groups of compressed air in the first compressed air duct and the second compressed air duct, the device obtains a driving force to the left or right, which is energy-saving and environmentally friendly, and has no pollution emissions.
