[0002] In the current cigarette manufacturing industry, the ZL29 forming machine is the mainstream equipment for producing filter rods. During the operation of the ZL29 forming machine, the nozzles in the YL19 spray chamber atomize and evenly spray the plasticizer onto the moving cigarette tow. If the atomization effect of the nozzles is poor, or if there are suspended and condensed plasticizer droplets in the spray chamber that are carried into the cigarette tow, the former will result in insufficient hardness of the finished filter rod, and the latter will cause serious quality defects such as cavities in the filter rod.

[0003] Currently, during production with materials on the equipment, due to lighting and atomization issues, operators cannot clearly observe the spraying effect of plasticizer in the spraying chamber. When quality defects in the finished filter rods occur due to poor atomization of the nozzles or suspended plasticizer droplets carried into the fiber bundle in the spraying chamber, operators cannot detect the potential quality problems and defects in time, which can easily lead to a large number of filter rods with quality issues. Maintenance personnel also find it difficult to quickly determine the equipment status when troubleshooting, which can result in prolonged equipment downtime and greatly affect equipment production.

[0044] Figure 1 This is a schematic diagram of the overall structure of a lighting device according to an embodiment of the present utility model. Figure 2 This is an installation diagram of a lighting device according to an embodiment of the present utility model. Figure 3 This is a connection diagram of a control system according to an embodiment of the present utility model. (In conjunction with...) Figure 1 , Figure 2 and Figure 3 As shown, the lighting device for the spray chamber includes: mounting components 1 and control system 2;

[0045] Mounting component 1 includes a mounting bracket 11 and a lighting lamp 12;

[0046] The mounting bracket 11 includes a fixed bracket 111 and a corner bracket 112; the fixed bracket 111 is fitted onto the observation window cover 3 of the spray chamber; the lighting lamp 12 is fixedly connected to the fixed bracket 111 through the corner bracket 112 so that the lighting lamp 12 emits light toward the observation window cover 3;

[0047] The power supply control terminal e of the control system 2 is electrically connected to the power supply response terminal f of the lighting lamp 12, and is used to control the working state of the lighting lamp 12.

[0048] The mounting component 1 can be used to install the lighting lamp 12, and the control system 2 can be used to control the operation of the lighting lamp 12. The mounting component 1 can be installed on the observation window cover 3 of the spray chamber cover. It is understood that the observation window cover 3 of the spray chamber is a structure in the prior art. This embodiment of the utility model, without changing the existing equipment structure and process, sets the mounting component 1 on the observation window cover 3, so that the staff can clearly observe the state inside the plasticizer spray chamber.

[0049] The mounting bracket 11 of the mounting component 1 serves to fix the lighting lamp 12 to the cover of the observation window 30. The lighting lamp 12 can be selected based on the structural and technological characteristics of the spray booth equipment, choosing an explosion-proof LED lamp that provides sufficient brightness and is not easily damaged, thereby improving the applicability and durability of the spray booth lighting device.

[0050] The mounting bracket 11 includes a fixed bracket 111 and a corner bracket 112. The fixed bracket 111 is fitted onto the cover of the observation window 30. Since the cover is located at the edge of the observation window 30, the fixed bracket 111 fits onto the cover of the observation window 30, which satisfies the function of fixing the fixed bracket 111 without affecting the visibility of the observation window 30. The fixed bracket 111 serves to connect with the observation window cover 30, and the corner bracket 112 serves to connect the lighting lamp 12 and the fixed bracket 111. Through the connection between the corner bracket 112, the fixed bracket 111, and the lighting lamp 12, the lighting lamp 12 can emit light towards the observation window 30, thereby illuminating the spray room.

[0051] In this system, the power supply control terminal e of the control system 2 can be used to output a signal to control the working state of the lighting lamp 12, and the power supply response terminal f of the lighting lamp 12 controls the working state of the lighting lamp 12 according to the received signal. The working state of the lighting lamp 12 can include turning the lighting on and turning the lighting off.

[0052] Specifically, during installation, the fixing bracket 111 is first fitted onto the observation window cover 3 of the spray chamber, and the lighting lamp 12 is fixedly connected to one end of the corner bracket 112. After assembly, the connecting components of the lighting lamp 12 and the corner bracket 112 are connected to the fixing bracket 111, thereby realizing the installation of a lighting device in the spray chamber. The control system 2 can control the working state of the lighting lamp 12, so that the lighting lamp 12 provides illumination to the spray chamber through the observation window 30.

[0053] The technical solution of this utility model embodiment sets up an installation component and a control system on the existing spray chamber structure. The installation component, including a lighting lamp, is installed on the observation window cover of the spray chamber. The control system controls the operation of the lighting lamp, so that the lighting lamp can provide illumination for the spray chamber. Without changing the equipment structure and process, it adds the function of clearly observing the state of the plasticizer spray chamber. This allows maintenance personnel to accurately grasp the internal state of the spray chamber while the equipment is running, thereby better serving production, improving product quality, and effectively preventing unqualified products from entering downstream processes.

[0054] Optional, Figure 4 This is a schematic diagram of the overall structure of a fixed bracket according to an embodiment of the present utility model, combined with... Figure 1 , Figure 2 and Figure 4 As shown, the fixed bracket 111 includes a fixed plate portion 1111 and a baffle portion 1112; along the first direction x, the size of the fixed plate portion 1111 is larger than the size of the observation window housing 3;

[0055] The baffle portion 1112 is fixedly disposed at both ends of the fixed plate portion 1111 and the angle between the baffle portion 1111 and the fixed plate portion 1111 is a fixed angle;

[0056] The lighting lamp 12 is fixedly mounted on the fixed bracket 111 via the corner bracket 112; the baffle portion 1112 is connected to the observation window cover 3.

[0057] The baffle portion 1112 is fixedly disposed at both ends of the fixing plate portion 1111. The fixing angle can be adapted to the cover of the observation window 30 to ensure that the baffle portion 1112 can be fixed on the observation window cover 3, for example, at 90°. The size of the fixing plate portion 1111 along the first direction x is larger than the size of the observation window cover 3 so that the baffle portion 1112 can be fitted onto the observation window cover 3, and it also facilitates the placement of the lighting lamp 12 on the fixing bracket 111 portion, ensuring the lighting range. In some embodiments, the size of the fixing plate portion 1111 along the first direction x is slightly larger than the size of the observation window cover 3.

[0058] For example, the observation window 30 is set to a rectangular structure, with the first direction x being the width direction of the observation window 30. In actual installation, the fixing plate portion 1111 can be an elongated structure that spans the observation window 30 along the first direction x. The angle between the baffle portion 1112 and the fixing plate portion 1111 is 90°. The baffle portion 1112 can overlap the observation window cover 3. The installation of the fixing bracket 111 is achieved by fixing the baffle portion 1112 to the observation window cover 3. After the fixing bracket 111 is installed, the lighting lamp 12 is installed on the fixing plate bracket so that the lighting lamp 12 emits light towards the observation window 30, ensuring the illumination range.

[0059] The solution of this utility model embodiment includes a fixed bracket comprising a fixed plate portion and a baffle portion. The fixed bracket is installed on the observation window housing by connecting the fixed plate portion and the baffle portion, thus ensuring the fixed installation of the lighting lamp and the lighting range.

[0060] Optional, Figure 5 This is a schematic diagram of the overall structure of a corner frame according to an embodiment of the present utility model, combined with... Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a threaded cylindrical pin 110 is provided on the fixing plate portion 1111; the corner bracket 112 includes a straight groove 120;

[0061] The fixed plate section 1111 is connected to the corner bracket 112 by passing through the straight groove 120 with a threaded cylindrical pin 110 and engaging with a nut.

[0062] The baffle portion 1112 includes a threaded hole 130; the baffle portion 1112 is connected to the observation window cover 3 by screwing a set screw into the threaded hole 130.

[0063] In consideration of the fact that the fixed bracket 111 is too close to the observation window 30 of the spray chamber during actual installation, and cannot be directly fixed to other parts by screws, a threaded cylindrical pin 110 is provided on the fixed plate section 1111. The fixed bracket 112 is achieved by the cooperation of the threaded cylindrical pin 110 and the nut.

[0064] The bracket 112 includes a straight groove 120. A threaded cylindrical pin 110 on the fixing plate portion 1111 passes through the groove and is tightened with a nut to secure the fixing plate portion 1111 to the bracket 112. Simultaneously, the design of the straight groove 120 effectively solves the problem of high dimensional accuracy requirements when the threaded cylindrical pin 110 mates with the hole, improving the ease of installation.

[0065] In order to ensure the airtightness of the observation window cover 3 of the spray chamber and prevent plasticizer leakage, threaded holes 130 are provided on the baffle portions 1112 at both ends of the fixing plate portion 1111. The baffle portions 1112 and the observation window cover 3 can be fixed by screwing the set screws into the threaded holes 130 from both sides of the observation window cover 3, so as to provide the function of fixing the lighting lamp 12 without affecting the airtightness of the spray chamber cover.

[0066] Understandably, since the baffle section 1112 is fixed by a set screw, the left and right positions of the fixed bracket 111 can be adjusted by loosening the set screw, thereby adjusting the position of the lighting lamp 12 so that the installation position of the lighting lamp is directly opposite the observation window 30 of the plasticizer spraying chamber, which can cover the entire plasticizer spraying chamber and improve the applicability of the device.

[0067] The technical solution of this utility model embodiment addresses the problem of ensuring the sealing of the spray chamber to prevent plasticizer leakage. It designs an installation component that ensures sealing. By using a fixing bracket with set screws and a fixing method that uses a threaded cylindrical pin and a straight groove, it effectively avoids the situation where the spray chamber is damaged and plasticizer leaks when the lighting device is installed and tightened on the observation window cover, thus improving the applicability of the installation component.

[0068] Optional, continue to refer to Figure 1 , Figure 2 and Figure 5 As shown, the corner bracket 112 includes a right-angle plate;

[0069] The right-angle plate includes a first portion 1121 and a second portion 1122 that are fixedly connected.

[0070] The first part 1121 includes a round hole, which is fixedly connected to the lighting lamp 12 by screws;

[0071] The second section 1122 includes a straight groove 120.

[0072] The corner bracket 112 may include a right-angle plate, which comprises a first portion 1121 and a second portion 1122 connected at a right angle. The first portion 1121 has a circular hole through which a screw is passed to connect to the lighting lamp 12. The second portion 1122 includes a straight groove 120, through which a threaded cylindrical pin 110 of the fixing plate portion 1111 passes and is connected to the corner bracket 112 via a nut engagement.

[0073] For example, as shown in Figure 5, the first part 1121 is a triangular face and the second part 1122 is a square face.

[0074] The technical solution of this utility model embodiment is to set the corner bracket including a first part and a second part, the first part and the second part are connected at right angles and each has different holes, thereby realizing the structural connection at different positions and ensuring the stability of the lighting device.

[0075] Optional, continue to refer to Figure 1 and Figure 2 As shown, mounting bracket 11 includes two;

[0076] The two mounting brackets 11 are fixedly connected to both ends of the lighting lamp 12, respectively.

[0077] To further ensure the stability of the lighting lamp 12, two mounting brackets 11 can be provided. The two mounting brackets 11 are respectively located at both ends of the observation window cover 3, and thus fixed to both ends of the lighting lamp 12.

[0078] The technical solution of this utility model embodiment improves the stability of the lighting device in the spraying room by setting two mounting brackets to fix both ends of the lighting lamp to the observation window cover.

[0079] Optional, continue to refer to Figure 1 , Figure 2 and Figure 3 As shown, the control system 2 includes a power supply component 21, a switch button 22, and a control unit 23;

[0080] The power supply assembly 21 includes a power output terminal a; the switch button 22 includes a first switch terminal b and a second switch terminal c; the control unit 23 includes a power supply receiving terminal d and a power supply control terminal e;

[0081] The power output terminal a is electrically connected to the first switch terminal b; the second switch terminal c is electrically connected to the power receiving terminal d.

[0082] The power supply component 21 can be used to provide operating power for the lighting device. The power output terminal a of the power supply component 21 can be used to output a power signal to the switch button 22.

[0083] The switch button 22 controls the on / off state of the lighting device, facilitating observation and adjustment by maintenance personnel and effectively preventing energy loss caused by prolonged operation of the lighting device. The first switch terminal b of the switch button 22 can receive power signals. The switch button 22 can be turned on and off according to the operator's control. When the switch button 22 is on, the first switch terminal b receives a power signal and outputs the power signal from the second switch terminal c; when the switch button 22 is off, the second switch terminal c receives a power signal but does not output a power signal.

[0084] The control unit 23 can monitor the status of the spraying chamber equipment in real time and control the working status of the lighting lamp 12 through algorithm processing. The power supply receiving terminal d of the control unit 23 can receive the power signal from the second switch terminal c and output a power supply signal from the power supply control terminal e to the power supply receiving terminal d of the lighting lamp 12 according to the operating status of the equipment. The lighting lamp 12 adjusts its working status according to the power supply signal.

[0085] In some embodiments, the power supply assembly 21 further includes a power receiving terminal h; the power receiving terminal h is electrically connected to the power output terminal g of the electrical cabinet 42 in the spray chamber. The electrical cabinet 42 in the spray chamber can provide power to the lighting device. Connecting the power supply assembly 21 to the electrical cabinet 42 ensures a stable operating voltage for the equipment while eliminating the need for additional wiring, avoiding the impact of repeated wiring on the equipment, and improving the durability of the device.

[0086] Specifically, during the circuit connection process, the power output terminal a of the power supply component 21 is electrically connected to the first switch terminal b of the switch button 22, the second switch terminal c of the switch button 22 is electrically connected to the power supply receiving terminal d of the control unit 23, and the power supply control terminal e of the control unit 23 is electrically connected to the power supply receiving terminal d of the lighting lamp 12.

[0087] For example, when the equipment is powered on, the electrical cabinet supplies power to the power supply component 21. The power supply component 21 assumes the equipment is in production mode, and the indicator light changes from off to green. The operator can adjust the working state of the control system 2 according to the equipment status. If the equipment is in production mode, the operator does not need to adjust the switch button 22; if the equipment is in maintenance mode, the operator can adjust the switch button 22 to the stop state, and the indicator light changes from green to red to prevent energy loss caused by turning on the lighting device.

[0088] The technical solution of this utility model embodiment is to set up a power supply component, a switch button and a control unit in the control system, and to control the lighting according to the equipment operation status by connecting the power supply component, the switch button and the control unit and the lighting.

[0089] Optional, continue to refer to Figure 1 , Figure 2 and Figure 3 As shown, the control system 2 also includes an indicator light 24; the indicator light 24 includes a working status response terminal i;

[0090] The switch button 22 also includes a working status output terminal j; the working status output terminal j is electrically connected to the working status response terminal i.

[0091] The indicator light 24 can output a light of a corresponding color according to the working state of the switch button 22.

[0092] For example, when the switch button 22 is turned on, the working status output terminal j of the switch button 22 outputs an on signal to the working status response terminal i of the indicator light 24, and the indicator light 24 is displayed in green; when the switch button 22 is turned off, the working status output terminal j of the switch button 22 outputs an off signal to the working status response terminal i of the indicator light 24, and the indicator light 24 is displayed in red.

[0093] Understandably, the indicator light 24 is designed to allow maintenance personnel to easily monitor the lighting status for control purposes.

[0094] The technical solution of this utility model embodiment is to set an indicator light and electrically connect the working status response terminal of the indicator light to the working status output terminal of the switch button, so as to realize the function of the indicator light displaying different information according to the working status of the lighting device.

[0095] Optional, continue to refer to Figure 1, Figure 2 and Figure 3 As shown, the control unit 23 also includes a first receiving terminal k and a second receiving terminal l;

[0096] The first receiving end k is electrically connected to the opening solenoid valve 411 of the cover 41 in the spray chamber;

[0097] The second receiving terminal 1 is electrically connected to the closing solenoid valve 412 of the cover 41 in the spray chamber.

[0098] The control unit 23 can monitor the operation of the spray chamber equipment through the first receiving terminal k and the second receiving terminal l. The cover 41 of the spray chamber includes two types of solenoid valves: an opening solenoid valve 411 for controlling the opening of the cover 41, and a closing solenoid valve 412 for controlling the closing of the cover 41. The first receiving terminal k is electrically connected to the opening solenoid valve 411 of the cover 41 in the spray chamber, and the second receiving terminal l is electrically connected to the closing solenoid valve 412 of the cover 41 in the spray chamber, so that the control unit 23 can receive the opening and closing signals of the cover 41 and then correspondingly control the working state of the lighting lamp 12.

[0099] For example, when the equipment is running normally, the control unit 23 monitors the equipment's operating status in real time. When the control unit 23 receives a signal that the cover 41 in the spray chamber is closed (the first receiver k does not output a signal, while the second receiver l outputs a signal), the control unit 23 outputs 24V voltage to the lighting lamp 12. After receiving the signal, the lighting control system 2 outputs light from the working lighting lamp 12 to illuminate the spray chamber, making it easier for operators to observe and control the atomization effect. At this time, the operator can adjust the position of the lighting lamp 12 by adjusting the set screws on the fixing bracket 111 of the mounting component 1 to achieve better lighting and observation effects. When the equipment stops running, the control unit 23 receives a signal that the cover 41 in the spray chamber is open (the first receiver k outputs a signal, while the second receiver l does not output a signal), and the control unit 23 stops outputting signals to the lighting lamp 12, causing the lighting lamp 12 to turn off.

[0100] The technical solution of this utility model embodiment designs a lighting control system for different equipment states such as equipment operation, shutdown, no-material operation, and maintenance. The control unit monitors the equipment status in real time and outputs corresponding control signals according to the current equipment status, so as to realize comprehensive closed-loop control of the lighting device in the spray room and improve the intelligence and automation of the lighting control system.

[0101] Optional, continue to refer to Figure 1 , Figure 2 and Figure 3 As shown, the control unit 23 also includes a third receiver m;

[0102] The third receiving terminal m is electrically connected to the operating status output terminal p of the equipment 43 in the spray chamber;

[0103] The power supply control terminal e includes a first voltage control terminal e1 and a second voltage control terminal e2; the first voltage control terminal e1 and the second voltage control terminal e2 are electrically connected to the power supply response terminal f respectively.

[0104] The control unit 23 can also be electrically connected to the operating status output terminal p of the equipment 43 in the spray chamber via the third receiving terminal m. The equipment 43 in the spray chamber can be a plasticizer spraying device 43, and the operating status of the lighting 12 can be controlled according to the operating status of the plasticizer spraying device 43.

[0105] The power supply control terminal e includes a first voltage control terminal e1 and a second voltage control terminal e2. The output voltages of the first voltage control terminal e1 and the second voltage control terminal e2 are different, but both supply power to the lighting lamp 12. The first voltage control terminal e1 and the second voltage control terminal e2 are electrically connected to the power supply response terminal f, and can switch different voltages to supply power to the lighting lamp 12 according to the working state of the plasticizer spraying equipment 43.

[0106] For example, when the atomization effect of the spray chamber is poor and the plasticizer nozzle needs to be checked, the maintenance personnel adjust the operating mode of the equipment 43 to "no material" and run the equipment 43. At this time, when the third receiving terminal m of the control unit 23 receives the "no material" signal and the spray chamber cover 41 closing signal from the second receiving terminal l, the control unit 23 outputs 120V voltage to the lighting lamp 12. After receiving the signal, the power supply response terminal f of the lighting lamp 12 outputs the maintenance lighting lamp 12 light to illuminate the plasticizer box, making it easier for maintenance personnel to observe and grasp the plasticizer spraying effect and improve maintenance efficiency.

[0107] The technical solution of this utility model embodiment provides two lighting functions according to the different lighting effects required by different working states of the equipment. One is a working light suitable for operators to observe the atomization effect inside the plasticizer spraying chamber when the equipment is in normal production, and the other is a maintenance light suitable for maintenance personnel to observe the spraying effect of the nozzles inside the plasticizer tank when the equipment needs maintenance, thereby improving the applicability of the lighting.

[0108] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
