Technical Field

[0001] This utility model relates to the field of cigarette production and processing technology, and in particular to a filter rod processing hot pressing molding device. Background Technology

[0002] Cigarettes are tobacco products made by rolling tobacco into strips using cigarette paper. They are also called paper cigarettes, cigarettes, or cigarette rolls. There are cigarettes with filters and cigarettes without filters, and they are also divided into mild and strong flavors. In order to filter out certain harmful substances (such as nicotine and tar) in cigarette smoke, most cigarettes are equipped with filter rods. During the production and processing, the filter rods need to be hot-pressed by a corresponding hot-pressing device.

[0003] For example, utility model patent application number 202222438488.9 discloses a filter rod hot pressing forming device, including a mounting base, a positioning component, and a hot pressing module; wherein, the mounting base is provided with a hot pressing channel for placing the filter rod, and the mounting base is provided with a hollow area communicating with the hot pressing channel; the positioning component is used to limit and constrain the axial position of the filter rod in the hot pressing channel.

[0004] Based on existing technology, most existing filter rod processing hot pressing molding devices are single-function, possessing only a single hot pressing function. They cannot rapidly cool the filter rod after hot pressing, thus preventing the filter rod from quickly forming and solidifying after hot pressing. This reduces the efficiency of filter rod production and processing to a certain extent. Furthermore, the mounting base is generally fixed by bolts, which is inconvenient for disassembly and installation, making daily maintenance and repair work difficult. Therefore, this utility model proposes a filter rod processing hot pressing molding device to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to propose a filter rod processing hot pressing molding device, which solves the problems of existing filter rod processing hot pressing molding devices being unable to rapidly cool the filter rod after hot pressing, thus preventing the filter rod from being quickly molded and cured after hot pressing, and the mounting base being generally fixed by bolts, making it inconvenient to disassemble and install.

[0006] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: a filter rod processing hot pressing forming device, including a hot pressing box, wherein the hot pressing box has a feed port and a discharge port respectively opened on the two side walls, the hot pressing box is symmetrically arranged with hot pressing plates driven to rise and fall by a lifting adjustment mechanism, a mounting seat is clamped between the two sets of hot pressing plates, the mounting seat has a hot pressing channel opened inside, and hollow grooves are opened on both the upper and lower sides of the mounting seat, a heating plate adapted to the hollow groove is fixed on the opposite side of the two sets of hot pressing plates, and a cooling seat is fixed on the side of the hot pressing box near the discharge port, the cooling seat has a cooling channel adapted to the hot pressing channel, and a cooling water coil is provided inside the cooling seat.

[0007] A further improvement is that: hanging rods are symmetrically fixed between the cooling base and the top of the hot press box; the inlet and outlet ends of the cooling water coil are located outside the cooling base and are respectively fixed with inlet and outlet pipes that extend to the outside of the hot press box.

[0008] A further improvement is that the lifting and adjusting mechanism includes a frame fixed to the inner walls of the upper and lower sides of the hot press box and a lead screw rotatably connected inside the frame and driven to rotate by a servo motor. A threaded plate is threaded onto the lead screw, and both sides of the threaded plate slide through to the outside of the frame. Push rods are symmetrically fixed between the threaded plate and the hot press plate.

[0009] A further improvement is that: the hot press plate has symmetrically fixed positioning protrusions on the side wall near the mounting base, and the upper and lower outer walls of the mounting base are provided with positioning grooves that are adapted to the positioning protrusions.

[0010] A further improvement is that a blower is fixed to the top of the inside of the hot press box near the feed inlet, and the air outlet of the blower is connected to a blower hood through a blower pipe.

[0011] A further improvement is that a dust collection box is fixed to the bottom of the hot press box near the feed inlet, and an exhaust fan is fixed to the bottom of the hot press box below the dust collection box. The air inlet of the exhaust fan extends into the dust collection box, and a dust filter is fixed inside the dust collection box.

By fixing a cooling seat inside the hot press box near the discharge port and setting a cooling water coil around the cooling channel inside the cooling seat, the filter rod can be cooled quickly after hot pressing, thereby enabling the filter rod to be quickly formed and solidified after hot pressing. This improves the production and processing efficiency of the filter rod to a certain extent. Furthermore, by clamping the mounting seat between two sets of hot press plates and driving the hot press plates to move up and down through a lifting and adjusting mechanism, the mounting seat can be easily disassembled and installed, facilitating daily maintenance and repair.

Detailed Implementation

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , Figure 2 , Figure 3As shown, this embodiment provides a filter rod processing hot pressing forming device, including a hollow hot pressing box 1 and a feed port 2 and a discharge port 3 respectively opened on the left and right side walls of the hot pressing box 1. The feed port 2 is used for feeding the filter rod to be hot pressed, and the discharge port 3 is used for discharging the filter rod after hot pressing. The bottom of the hot pressing box 1 is fixed with a base by symmetrically distributed support rods to provide stable support for the hot pressing box 1. The front of the hot pressing box 1 is hinged with a box door that is symmetrically distributed on the left and right. The hot pressing box 1 has two sets of hot pressing plates 4 symmetrically distributed on the top and bottom in the middle position inside the hot pressing box 1. The two sets of hot pressing plates 4 are respectively raised and lowered by the hot pressing box 1 to the side walls. The adjustment mechanism drives and moves the filter rod up and down. A set of mounting seats 5 for hot pressing is clamped between the two sets of hot press plates 4. The mounting seat 5 has a hot pressing channel 6 for the filter rod to pass through. The upper and lower surfaces of the mounting seat 5 are both provided with hollow grooves 7. A heating plate 8 for providing heat for hot pressing the filter rod is fixed to the side wall of the hot press plate 4 near the mounting seat 5 by bolts. The heating plate 8 is adapted to and embedded in the hollow groove 7. By clamping the mounting seat 5 between the two sets of hot press plates 4 and driving the hot press plate 4 to move up and down through the lifting adjustment mechanism, the mounting seat 5 can be easily installed and removed.

[0020] A cooling seat 9 for rapid cooling of the filter rod is fixed inside the hot press box 1 on the side near the discharge port 3. The cooling seat 9 has a cooling channel 10 that corresponds to and is adapted to the position of the hot press channel 6. The cooling channel 10 is used for the filter rod after hot pressing to pass through. The cooling seat 9 is provided with a cooling water coil 11 for containing cooling water. The cooling water coil 11 is arranged around the cooling channel 10. By fixing the cooling seat 9 inside the hot press box 1 on the side near the discharge port 3 and setting the cooling water coil 11 around the cooling channel 10 inside the cooling seat 9, the filter rod can be rapidly cooled after hot pressing, so that the filter rod can be quickly formed and solidified after hot pressing.

[0021] The top of the cooling base 9 is symmetrically fixed with bolts to the top of the suspension rods 12. The top of the suspension rods 12 is fixed to the top of the inside of the hot press box 1 with bolts to achieve the suspension and fixation of the cooling base 9. The inlet and outlet of the cooling water coil 11 are located outside the cooling base 9 and are respectively fixed with an inlet pipe 13 and an outlet pipe 14. The inlet of the inlet pipe 13 extends to the outside of the hot press box 1 and is connected to the external cooling water supply equipment through a pipeline to inject cooling water into the cooling water coil 11. The outlet of the outlet pipe 14 extends to the outside of the hot press box 1 and is connected to the external cooling water recovery equipment through a pipeline to discharge the cooling water in the cooling water coil 11, so that the cooling water flows continuously in the cooling water coil 11.

[0022] The lifting and adjusting mechanism includes a frame 15, a servo motor 16, and a lead screw 17. The frame 15 has two sets of screws, which are fixed to the inner walls of the upper and lower sides of the hot press box 1 respectively. The servo motor 16 has two sets of screws, which are fixed to the top and bottom of the hot press box 1 respectively. The lead screw 17 is rotatably connected to the inside of the frame 15 through a bearing. The end of the lead screw 17 near the servo motor 16 passes through the outside of the hot press box 1 through a bearing and is fixedly connected to the output shaft of the servo motor 16. A threaded plate 18 is threaded onto the lead screw 17. The left and right sides of the threaded plate 18 slide through the left and right side walls of the frame 15 and extend to the outside of the frame 15 respectively. Push rods 19, which are symmetrically distributed on the left and right sides, are fixed between the threaded plate 18 and the hot press plate 4 through bolts.

[0023] Positioning protrusions 20 are fixed at the four corners of the side wall of the hot press plate 4 near the mounting base 5. Positioning grooves 21 are provided at the four corners of the upper and lower outer walls of the mounting base 5. The positioning grooves 21 are matched with the positioning protrusions 20. When the mounting base 5 is clamped between the two sets of hot press plates 4, the positioning protrusions 20 are embedded in the positioning grooves 21, which plays a positioning role for the mounting base 5.

[0024] Inside the hot press chamber 1, a blower 22 is fixed to the top left side by bolts. The air outlets on both sides of the blower 22 are fixed with air pipes 23. The bottom of the two sets of air pipes 23 are fixed with a set of air blowing hoods 24. The blower 22 drives the air pipes 23 and air blowing hoods 24 to blow air downwards, blowing off the dust on the filter rods before entering the hot press channel 6, ensuring the cleanliness of the filter rods.

[0025] A dust collection box 25 located below the blower hood 24 is fixed to the bottom left side of the interior of the autoclave 1 by bolts. An exhaust fan 26 is fixed to the bottom left side of the exterior of the autoclave 1 by bolts. There are two sets of exhaust fans 26, which are symmetrically distributed on the left and right sides below the dust collection box 25. The air inlet of the exhaust fan 26 extends into the interior of the dust collection box 25. A dust filter screen is fixed inside the dust collection box 25. When the exhaust fan 26 is turned on, it draws air into the dust collection box 25, so that the dust blown off the filter rod can be sucked into the dust collection box 25 and intercepted by the dust filter screen.

[0026] Both the feed inlet 2 and the discharge outlet 3 are rotatably connected to the inner side of the guide wheels 27 that are symmetrically distributed vertically. The gap between the two sets of guide wheels 27 is just enough to allow the filter rod to pass through. Inside the hot press box 1, on the side near the feed inlet 2, there are support wheels 28 that are equidistantly distributed, which support the filter rod.

[0027] When filter rods need to be hot-pressed during the production process, the filter rods to be hot-pressed are transferred into the hot-press box 1 from the feed port 2 on the left side of the hot-press box 1. They first pass through the hot-pressing channel 6 on the mounting base 5. When the filter rod enters the hot-pressing channel 6, the heating plate 8 embedded in the hollow groove 7 is used to hot-press the filter rod in the hot-pressing channel 6. After the hot-pressing is completed, the filter rod enters the cooling channel 10 on the cooling base 9. At this time, external cooling water is connected to the cooling water coil 11 in the cooling base 9 to achieve rapid cooling of the filter rod through heat exchange. The cooled filter rods are then discharged from the discharge port 3 on the right side of the hot-press box 1, realizing the continuous processing of filter rod hot-pressing and cooling curing.

[0028] When it is necessary to remove the mounting base 5 between the two sets of hot press plates 4 for maintenance and repair, first use the lifting and adjusting mechanism to drive the hot press plate 4 to move away from the mounting base 5, that is, the two sets of hot press plates 4 move in opposite directions, which can release the clamping and fixing of the mounting base 5. Then, the mounting base 5 can be directly removed to complete the convenient disassembly. During installation, the mounting base 5 is placed between the two sets of hot press plates 4, and then the lifting and adjusting mechanism is used to drive the two sets of hot press plates 4 to move towards each other, which can clamp and fix the mounting base 5, thus achieving convenient installation.
