[0006] 2. The cutter shaft and the driven shaft are checked one by one, and it is found that the bearings of the main shaft and the driven shaft are rusted in different degrees, and the bearings are obviously felt to be stuck and not flexible during the manual rotation, which causes the upstream bakelite gear to bear a large force during the operation process;
[0007] 3. The bakelite gear in the cutting drum of the cut stem machine is checked, and it is found that the gap between the teeth of the bakelite gear and the planetary gear is adhered with tobacco foam and dust, the meshing of the two gear teeth is tight, the side gap is small, and the manual cutting is laborious, which causes the upstream bakelite gear to bear a large force during the operation process. INVENTION CONTENTS
[0008] Therefore, the utility model aims at providing a tobacco cutting equipment knife roll internal clean blowing dedusting and heating dampness removal device, solving the problem that the frequency of the faults such as the wear and tear and the tooth breakage of the bakelite gear is relatively high in the prior art, keeping the inside of the knife roll clean and dry, making the running environment of the cutter mechanism good, ensuring the continuous operation of the tobacco cutting equipment, meeting the requirements of the cut stem machine on the process, improving the production efficiency, and improving the performance of the equipment.
[0009] This utility model solves the above-mentioned technical problems through the following technical means: a dust removal and heating device for the internal cleaning and dehumidification of the cutting roller of a shredding equipment, wherein an air inlet and an air outlet are respectively provided at both ends of the cutting drum, the air inlet being used to connect to a compressed air source, and the air outlet being used to connect to the main dust removal pipeline of the workshop; an air filter pressure reducing valve, a heat exchange tank and a solenoid valve are also connected sequentially between the compressed air source and the air inlet.
[0010] The heat exchange tank has a compressed air outlet at the top and a compressed air inlet at the bottom. The heat exchange tank is equipped with a spiral heat exchange tube, and the two ends of the heat exchange tube pass through the top and bottom of the heat exchange tank to form a steam inlet and a steam outlet, respectively.
[0011] Optionally, the heat exchange tank is a pressure vessel. This is used to ensure the safety of the heat exchange tank.
[0012] Optionally, the outer surface of the pressure vessel tank is covered with an insulation layer to reduce heat loss from the heat exchange tank.
[0013] Optionally, the heat exchange tube is evenly distributed with several heat exchange fins. This increases the heat exchange contact area and improves heat exchange efficiency.
[0014] Optionally, the air filter pressure reducing valve has a removable PE microporous filter element. This facilitates filter element replacement and maintains the cleanliness of the compressed air.
[0015] Optionally, the piping between the compressed air outlet and the air inlet can be made of insulated compressed air pipe to reduce heat loss.
[0016] Optionally, the steam inlet is used to connect to the workshop's high-temperature steam pipeline. This makes full use of existing workshop resources and reduces modification and operating costs.
[0017] The beneficial effects of this utility model are:
[0018] 1. This utility model, by opening an air inlet and an air outlet on the cutting drum of the cutter roller, allows the compressed air from the workshop to pass through an air filter pressure reducing valve, a heat exchange tank, and a solenoid valve, resulting in compressed air with stable pressure, dryness, cleanliness, and relatively high temperature. The heated compressed air is blown into the interior of the cutter roller by the cutting drum, ensuring that there is no soot or dirt adhering to the tooth grooves of the bakelite gears and that the tooth clearance is normal. At the same time, the dry hot air allows the moisture inside the cutter roller to evaporate through heating, and then connects to the main dust removal pipe through the air outlet to achieve dust removal and moisture removal effects.
[0019] 2. This utility model makes full use of the compressed air resources used in the silk making workshop, such as the silk making machine, and the high-temperature steam resources used in the leaf moistening machine and the silk drying machine, resulting in low operating costs and good dust removal and dehumidification effects inside the cutter roller. At the same time, the continuous supply of compressed air keeps the cutting drum under positive pressure, preventing water, smoke, dust and other impurities from entering the inside of the cutter roller, thereby greatly reducing the frequency of failures such as wear and tooth breakage of the bakelite gear.

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can understand the advantages and effects of this utility model from the content disclosed in this specification. It should be noted that the illustrations provided in the following embodiments are for illustrative purposes only and represent schematic diagrams, not actual pictures.

To better illustrate the embodiments of this utility model, some components in the figures may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the figures for those skilled in the art.

In the description of this utility model, it should be understood that if terms such as "upper", "lower", "left", "right", "front", "rear", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figure, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above-mentioned terms can be understood according to the specific circumstances.
[0025] like Figs. 1-2As shown, this utility model provides a dust removal and heating dehumidification device for the internal cleaning and heating of the cutting roller of a slicing equipment. An air inlet and an air outlet are respectively provided at both ends of the cutting drum 1. The air inlet is used to connect with a compressed air source, and the air outlet is used to connect with the main dust removal pipeline of the workshop. An air filter pressure reducing valve 2, a heat exchange tank 3, and a solenoid valve 4 are also connected in sequence between the compressed air source and the air inlet.
[0026] In this embodiment, the heat exchange tank 3 has a compressed air outlet 31 at the top and a compressed air inlet 32 at the bottom. A spiral heat exchange tube 33 is installed inside the heat exchange tank 3. The two ends of the heat exchange tube 33 pass through the top and bottom of the heat exchange tank 3, respectively, forming a steam inlet 331 and a steam outlet 332. The steam inlet 331 is used to connect with the high-temperature steam pipeline in the workshop (used in existing leaf-moistening machines, yarn-drying machines, and other production processes in the yarn-making workshop). The compressed air enters from the bottom and exits from the top, while the high-temperature steam enters from the top and exits from the bottom; these two configurations are reversed, which helps ensure the heat exchange effect of the compressed air. Condensate that may be generated from steam condensation inside the heat exchange tube 33 can flow out from the steam outlet 332 at the bottom.
[0027] In this embodiment, in order to reduce the heat loss of steam and ensure the safety of the heat exchange tank 3, the heat exchange tank 3 is a pressure vessel tank. The outer surface of the pressure vessel tank is covered with a heat insulation layer material, such as polyurethane foam. Similarly, the pipeline between the compressed air outlet 31 and the air inlet can also be an insulated compressed air pipe.
[0028] In this embodiment, to improve the heat exchange efficiency of steam and compressed air, several heat exchange fins are evenly distributed on the heat exchange tube 33. Both the heat exchange tube and the heat exchange fins are made of thermally conductive materials, such as aluminum alloy which is also corrosion resistant.
[0029] In this embodiment, the air filter pressure reducing valve 2 has a removable PE microporous filter element. The air filter pressure reducing valve 2 can be obtained through commercial channels. It mainly sets the outlet pressure by adjusting the spring pressure, uses the diaphragm to sense changes in the outlet pressure, and drives the piston to adjust the size of the flow area of the throttling part of the main valve through the opening and closing of the pilot valve to achieve the pressure reduction and stabilization function.
[0030] It should be understood that the control of the air filter pressure reducing valve 2 and the solenoid valve 4 can be integrated into the shredder, and the heat exchange tank 3 can also be equipped with existing pressure relief valves, pressure gauges, etc. Existing valves can be installed on the air outlet, steam inlet 331, steam outlet 332, etc. to control their opening and closing.
[0031] The working principle of this utility model is as follows:
[0032] After passing through the air filter pressure reducing valve 2, heat exchange tank 3, and solenoid valve 4, the compressed air entering the cutting drum 1 has the characteristics of stable pressure, dryness, cleanliness, and relatively high temperature. The heated compressed air is blown into the inside of the cutter roller by the cutting drum 1, ensuring that there is no soot or dirt adhering to the tooth groove of the bakelite gear and that the tooth clearance is normal. At the same time, the dry hot air allows the water vapor inside the cutter roller to evaporate through the heating of the hot air and connect to the main dust removal pipe through the air outlet hole to achieve the effects of dust removal and moisture removal.
[0033] After adding the dust removal and dehumidification device of this utility model to the existing SQ316B type oblique blade horizontal roller shredder, the amount of smoke and dust adhering to the tooth grooves of the bakelite gear is significantly reduced. The tooth clearance between the bakelite gear and the planetary gear is normal, with an average tooth clearance of 0.04mm. The internal moisture of the cutter roller body is significantly improved, making the internal parts less prone to corrosion, ensuring the effectiveness of the parts and the lubrication effect. Finally, the feeding system operates smoothly, ensuring the good performance of the shredder and ensuring that the shredding quality meets the process requirements. This has positive significance for the continuous operation of the equipment and the steady-state control of quality.
[0034] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
