Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology for tobacco processing, specifically to a cooling device for a sealer of a filter rod forming machine. Background Technology

[0002] Cigarette filters are formed by rolling cellulose acetate tows into a circle using a cigarette rolling gun and then wrapping them inside a forming paper coated with sealing adhesive. Filter rod forming machines are specifically used to produce cigarette filters, and the sealing device within it is used to cure the sealing adhesive on the forming paper. Specifically, the sealing adhesive is a hot melt adhesive, which the sealing device rapidly cools to solidify. When cooling the sealing device, either an air-cooled or water-cooled heat exchanger is typically used. However, air-cooled heat exchangers require large water tanks and fans, while water-cooled heat exchangers require large control cabinets and heat exchangers. This forces the cooling device to be fixed to the outside of the filter rod forming machine, occupying a large space and being aesthetically unappealing. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0046] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0047] According to an embodiment of the present invention, a cooling device for a sealer of a filter rod forming machine is provided, comprising: a first support assembly 1; a second support assembly 2, which is angled to the first support assembly 1; a compressor 3, which is fixed to the first support assembly 1 and disposed away from the second support assembly 2; a water storage component 4, which stores chilled water, is fixed to the first support assembly 1 and disposed at a distance from the compressor 3; a first control component 5, which is electrically connected to the compressor 3, fixed to the first support assembly 1, and disposed at a distance from the water storage component 4; an expansion valve 6, which is disposed above the first support assembly 1 and close to the second support assembly 2; an evaporator 7, which is connected to the compressor 3, the water storage component 4, and the expansion valve 6, and is fixed to the side of the second support assembly 2 close to the first support assembly 1; and a condenser 8, which is connected to the compressor 3 and the expansion valve 6, fixed to the second support assembly 2, and disposed at a distance from the evaporator 7.

Specifically, the sidewall of the pressure booster 9 is disposed close to the first support component 202, and the first support component 202 is provided with the first opening 201. By providing the first opening 201 on the second support component 2, it is convenient to maintain the pressure booster 9; by disposing the sidewall of the pressure booster 9 close to the first support component 202, the sidewall of the pressure booster 9 can be maintained through the first opening 201. As an alternative implementation, the first support component 1 may also be provided with the first opening 201, which is disposed opposite to the pressure booster 9. As an alternative implementation, the sidewall of the pressure booster 9 may also be disposed close to the second support component 203, and the second support component 203 may be provided with the first opening 201.

[0059] like Figure 2As shown, in one embodiment, the tail end of the booster 9 and the expansion valve 6 are disposed near the second support member 203. The second support member 203 has a second opening 204, which is disposed opposite to the tail end of the booster 9 and the expansion valve 6. The second opening 204 on the second support member 203 facilitates maintenance of the tail end of the booster 9 and the expansion valve 6.

Similarly, the second opening 204 may be disposed only opposite to the tail end of the booster 9 or only opposite to the expansion valve 6.

[0060] like Figure 2 As shown, in one embodiment, the cooling device for the sealer of the filter rod forming machine includes: a second control component 10, connected to the compressor 3 and fixed to the side wall of the water storage component 4.

The inlet of the three-way valve 12 is connected to a water pump, the first outlet is connected to the sealer, and the second outlet is connected to the evaporator. In use, the three-way valve 12 controls the flow direction of the chilled water according to a signal from the host computer. When the three-way valve opens the first outlet and closes the second outlet, the chilled water flows through the three-way valve 12 to the sealer for use. When the three-way valve opens the second outlet and closes the first outlet, the chilled water flows back to the evaporator through the three-way valve 12, and the sealer stops cooling. As an alternative implementation, when the cooling device is applied to other structures, the three-way valve 12 may not be provided.

[0064] In one embodiment, the working principle of the cooling device for the sealer of the filter rod forming machine is as follows:

[0065] In the heat absorption circuit, the high-temperature chilled water passes through the evaporator, where it absorbs heat and cools down before flowing into the water tank and being returned by the water pump.

[0066] In the heat transfer circuit, the liquid refrigerant absorbs heat from the chilled water in the evaporator and vaporizes to form a gaseous refrigerant. It is then drawn into the compressor and pressurized to form a high-pressure, high-temperature gaseous refrigerant, which is then sent to the condenser. In the condenser, it releases heat and condenses to form a high-pressure liquid refrigerant. The heat is transferred to the cooling water, and the temperature decreases. The high-pressure liquid refrigerant is depressurized through the expansion valve to form a low-temperature, low-pressure liquid refrigerant, which returns to the evaporator for repeated operation.

[0067] In the heat dissipation circuit, the cooler water at a lower temperature passes through the condenser, absorbs the heat from the condenser, and then flows back after the heat is released to the outside.

[0068] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
