Description

Technical Field

[0001] The utility model relates to the technical field of cigarette machinery and equipment, and more specifically to a large pressing plate cooling system of a cigarette making machine. Background Art

[0002] Cigarettes are rolled and formed by cigarette making machines. The cigarette making machine rolls the loose, uniform, and weight-compliant tobacco delivered by the feeder into continuous tobacco strips, which are then cut into double-length cigarettes by the cutting device and transported to the filter tip attachment machine. The process of cigarette paper forming by the cigarette making machine is mainly completed by the cigarette gun bottom plate, cigarette tongue, small pressing plate, large pressing plate, gluing device, and soldering iron. The cigarette tongue, small pressing plate, large pressing plate, and cigarette gun bottom plate form a circular channel, and the cigarette paper wraps the tobacco and runs in the circular channel. The circular channel compresses the tobacco bundle, causing the shape of the tobacco bundle to change to a round shape, which is consistent with the product design specifications.

[0003] After the cigarette paper wraps the tobacco, glue needs to be applied on one side of the cigarette paper so that the cigarette paper can completely wrap the tobacco bundle. Then the two sides of the cigarette paper are glued together to form a round cigarette rod. Therefore, a cut corner is processed at the exit of the small pressing plate. After the cigarette paper and the tobacco bundle run out of the small pressing plate, one side of the cigarette paper is exposed from the cut corner, and glue is applied by the nozzle in the gluing device. After gluing, the large pressing plate presses the exposed cigarette paper back and sticks it to the other side of the cigarette paper. Finally, the glue is dried by a soldering iron, so that a cigarette rod that meets the requirements is formed.

[0004] However, when the cigarette making machine runs for a long time, the temperature is already very high due to the friction between the large pressing plate, the cloth belt and the cigarette rods. After measurement, the highest temperature may reach about 100°C. In the process of curling and gluing the cigarette paper by the large pressing plate, the glue may have been dried out by the temperature of the large pressing plate, resulting in the cracked edge of the formed cigarette and unstable circumferential adhesion of the cigarette.

[0005] Therefore, how to provide a cooling system for a large pressing plate of a cigarette making machine has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0030] like Figures 1 to 3 As shown, the embodiment of the utility model provides a large pressing plate cooling system for a cigarette making machine, comprising: a large pressing plate 1, a cooling component 5 and a detection component.

[0031] The large pressing plate 1 is fixed on the cigarette making machine 8, and a cloth tape fixing channel 11 is provided at the bottom of the large pressing plate 1. The large pressing plate 1 is also provided with an air intake channel 2, a first exhaust channel 3, and a second exhaust channel 4 located above the cloth tape fixing channel 11, and the second exhaust channel 4 is respectively connected to the first exhaust channel 3 and the air intake channel 2. Specifically, the air intake channel 2 is connected to the first end of the second exhaust channel 4, and the first exhaust channel 3 is connected to the middle position of the second exhaust channel 4.

[0032] The cooling assembly 5 includes a connecting hose 51 and a cooler 52. The first end of the connecting hose 51 is in communication with the air intake passage 2, and the second end of the connecting hose 51 is in communication with the cooler 52. The cooler 52 is used to introduce cold air into the air intake passage 2. Specifically, the first end of the connecting hose 51 is inserted into the interior of the air intake passage 2, or the first end of the connecting hose 51 is arranged toward the air intake passage 2, so that the cooler 52 introduces cold air into the air intake passage 2 through the connecting hose 51.

[0033] The cooler 52 is a vortex tube cooler 52 with high heat dissipation efficiency and stable heat dissipation.

[0034] The detection component is used to detect the temperature of the large platen 1 and control the cooler 52 to turn on or off. Specifically, when the detection component detects that the temperature of the large platen 1 is greater than the preset temperature, the detection component controls the cooler 52 to turn on and operate the cooler 52. When the detection component detects that the temperature of the large platen 1 is less than the preset temperature, the detection component controls the cooler 52 to turn off and stop the cooler 52 from operating.

[0035] When the large pressing plate 1 is working normally, when the detection component detects that the temperature of the large pressing plate 1 is greater than the preset temperature, the detection component controls the cooler 52 to work, and the cooler 52 introduces cold air to the air inlet channel 2 through the connecting hose 51, and diverts the cold air to the first exhaust channel 3 and the second exhaust channel 4, thereby reducing the temperature of the large pressing plate 1, so that the temperature of the large pressing plate 1 can be maintained at an operating temperature of about 40°C even if it runs continuously, avoiding the curling of cigarette paper and solidification of glue due to the excessively high temperature of the large pressing plate 1, preventing the cracking of formed cigarettes and the instability of the circumference of cigarettes, reducing the number of cracked cigarettes and reducing the standard deviation of the circumference fluctuation of cigarettes.

[0036] The utility model provides an air intake channel 2, a first exhaust channel 3 and a second exhaust channel 4 located above the cloth tape fixing channel 11 on the large pressing plate 1, and the second exhaust channel 4 is respectively connected with the first exhaust channel 3 and the air intake channel 2; the first end of the connecting hose 51 is connected with the air intake channel 2, and the second end of the connecting hose 51 is connected with the cooler 52. When the large pressing plate 1 is working normally, when the detection component detects that the temperature of the large pressing plate 1 is greater than the preset temperature, the detection component controls the cooler 52 to work, and the cooler 52 introduces cold air to the air intake channel 2 through the connecting hose 51, and diverts the cold air to the first exhaust channel 3 and the second exhaust channel 4, thereby reducing the temperature of the large pressing plate 1, avoiding the problem of reduced quality of cigarettes due to excessively high temperature of the large pressing plate 1, improving production efficiency and quality of finished cigarettes, and reducing the labor intensity of operators.

[0037] In one embodiment of the cooling system of the large pressing plate of the cigarette making machine of the utility model, as Figures 1 to 3 As shown, the large pressure plate 1 has an air intake connection port 12 , and the first end of the connecting hose 51 and the first end of the air intake channel 2 are both in communication with the air intake connection port 12 .

[0038] The utility model sets an air intake connection port 12 on the large pressure plate 1, so that the first end of the connecting hose 51 and the first end of the air intake channel 2 are connected to the air intake connection port 12, so that the cold air blown out by the connecting hose 51 can be smoothly introduced into the air intake channel 2, effectively improving the cooling effect.

[0039] In one embodiment of the cooling system of the large pressing plate of the cigarette making machine of the utility model, the large pressing plate 1 has a first exhaust port 13 and a second exhaust port 14, and the first exhaust port 13 and the second exhaust port 14 are respectively connected to the first exhaust channel 3 and the second exhaust channel 4. The air inlet connection port 12 and the first exhaust port 13 are both arranged on the side wall of the large pressing plate 1, and the second exhaust port 14 is arranged at the end of the large pressing plate 1.

[0040] Specifically, the diameter of the second exhaust port 14 is greater than the diameter of the second exhaust passage 4, thereby making the cold air smoothly discharged from the second exhaust passage 4. The second exhaust port 14 is in the shape of a bell mouth.

[0041] The utility model arranges the first exhaust port 13 and the second exhaust port 14 on the large pressure plate 1, so that the first exhaust port 13 and the second exhaust port 14 are connected to the first exhaust channel 3 and the second exhaust channel 4 respectively, thereby ensuring the conduction effect between the intake channel 2 and the first exhaust channel 3 and the second exhaust channel 4, so that the cold air introduced into the intake channel 2 can be discharged from the first exhaust port 13 and the second exhaust port 14 after completing heat exchange in the intake channel 2, the first exhaust channel 3 and the second exhaust channel 4.

[0042] In one embodiment of the cooling system of the large pressing plate of the cigarette making machine of the utility model, as Figure 2 As shown, the air intake channel 2 and the first exhaust channel 3 are both extended along the width direction of the large pressure plate 1, the second exhaust channel 4 is extended along the length direction of the large pressure plate 1, and the first exhaust channel 3 and the air intake channel 2 are arranged in parallel.

[0043] Specifically, there is a certain distance between the first exhaust passage 3 and the intake passage 2, thereby increasing the area of ​​the interior of the large pressure plate covered by the cold air.

[0044] The utility model extends the air intake channel 2 and the first exhaust channel 3 along the width direction of the large pressure plate 1, and extends the second exhaust channel 4 along the length direction of the large pressure plate 1, and the first exhaust channel 3 is parallel to the air intake channel 2, so that the air intake channel 2, the first exhaust channel 3 and the second exhaust channel 4 can cover a larger area inside the large pressure plate 1, so that the cold air covers more positions, thereby improving the rapidity of reducing the temperature of the large pressure plate 1.

[0045] In one embodiment of the cooling system of the large pressing plate of the cigarette making machine of the utility model, as Figure 2 As shown, the second exhaust channel 4 includes a first channel section 41 and a second channel section 42. The first end of the first channel section 41 is connected to the second exhaust port 14, the second end of the first channel section 41 is connected to the first exhaust channel 3 and the first end of the second channel section 42 respectively, and the second end of the second channel section 42 is connected to the intake channel 2.

[0046] The utility model connects the first end of the first channel section 41 with the second exhaust port 14, the second end of the first channel section 41 is respectively connected with the first exhaust channel 3 and the first end of the second channel section 42, and the second end of the second channel section 42 is connected with the intake channel 2, so that after the cold air enters the intake channel 2, it is first introduced into the second channel section 42 of the second channel section 42, and then flows to the first channel section 41 and the first exhaust channel 3 respectively, and finally is discharged from the first exhaust port 13 and the second exhaust port 14, thereby improving the exhaust efficiency and further improving the cooling efficiency.

[0047] In one embodiment of the cooling system of the large pressing plate of the cigarette making machine of the utility model, as Figure 2 As shown, the diameter of the first channel section 41 is greater than the diameter of the second channel section 42 , and the diameter of the first channel section 41 gradually decreases from the first end of the first channel section 41 toward the second end of the first channel section 41 .

[0048] The utility model sets the diameter of the first channel section 41 to be larger than the diameter of the second channel section 42, and the diameter of the first channel section 41 is gradually reduced from the first end of the first channel section 41 to the second end of the first channel section 41, thereby facilitating the entry of cold air in the air intake channel 2 into the second channel section 42, and effectively improving the pressure of the airflow in the second channel section 42, so that the cold air flow can quickly circulate in the first exhaust channel 3 and the first channel section 41.

[0049] In one embodiment of the cooling system of the large pressing plate of the cigarette making machine of the utility model, as Figures 1 to 3 As shown, the large pressing plate 1 is further provided with a mounting hole 15 , and the mounting hole 15 is arranged on one side of the cloth belt fixing channel 11 .

[0050] The detection component includes a temperature sensor 6 and a controller (not shown in the figure). The controller is electrically connected to the temperature sensor 6. The temperature sensor 6 is used to detect the temperature inside the large pressure plate 1. The controller is used to control the start and stop of the cooler 52. The temperature sensor 6 is arranged in the mounting hole 15.

[0051] In this embodiment, the mounting hole 15 is located between the plane formed by the cloth tape fixing channel 11 and the plane formed by the air intake channel 2, and the length of the mounting hole 15 extends along the length of the large pressure plate 1, so that the temperature sensor 6 can measure the temperature of each position of the large pressure plate 1.

[0052] When the temperature sensor 6 detects that the temperature of the large platen 1 is greater than the preset temperature, the temperature sensor 6 transmits a signal to the controller, and the controller controls the cooler 52 to start working according to the signal. The cooler 52 introduces cold air to the intake channel 2 through the connecting hose 51, and diverts the cold air to the first exhaust channel 3 and the second exhaust channel 4, thereby reducing the temperature of the large platen 1. When the temperature sensor 6 detects that the temperature of the large platen 1 is less than the preset temperature, when the temperature sensor 6 detects that the temperature of the large platen 1 is greater than the preset temperature, the temperature sensor 6 transmits a signal to the controller, and the controller controls the cooler 52 to stop working according to the signal.

[0053] The utility model electrically connects the controller with the temperature sensor 6, the temperature sensor 6 is used to detect the temperature inside the large pressing plate 1, and a mounting hole 15 is provided on the large pressing plate 1, so that the mounting hole 15 is arranged on one side of the cloth belt fixing channel 11, thereby ensuring the sensitivity of the temperature sensor 6 in detecting the internal temperature of the large pressing plate 1, and effectively improving the cooling efficiency.
