Description

Technical Field

[0001] The utility model relates to a machine for manufacturing cigars, in particular to a device for wrapping and pressing cigars. Background Art

[0002] Cigars are a unique type of tobacco product, consisting of a filler, binder, and wrapper. The traditional cigar-rolling process primarily involves rolling the raw material, shaping the raw material, and applying the wrapper. During the rolling process, the filler and binder tobacco leaves are laid flat on a rolling board. The filler leaves are then tightly bundled and placed on the binder leaves for rolling. The resulting tobacco embryo is then shaped to ensure a smooth and flat surface. Finally, a high-quality wrapper is applied to the shaped tobacco embryo to create the finished cigar.

[0003] Currently, there are two main methods for shaping tobacco preforms. One is manual shaping, which requires high skill from the roller and can easily affect the quality of the cigar. Another method uses a shaping mold. For example, Chinese Utility Model Patent No. CN215381402U discloses a cigar shaping mold that includes an upper and lower mold plates that are interlocked. A lower mold core and an upper mold core are positioned between the lower and upper mold plates, allowing for quick assembly and disassembly. The top surface of the lower mold core is provided with multiple lower grooves with semicircular cross-sections, while the bottom surface of the upper mold core is provided with multiple upper grooves with semicircular cross-sections. The upper and lower grooves combine to form a cylindrical structure. During use, the rolled cigar is placed in the lower grooves, the upper mold core and upper mold plate are closed, and the upper and lower mold plates are locked together, thereby compressing the cigar between the upper and lower grooves.

[0004] Using the above-mentioned shaping mold to shape cigar embryos can realize batch operation and improve the efficiency of embryo shaping. However, the embryos are clamped by the upper and lower mold cores, and the force on the embryos is mainly concentrated in the upper and lower directions. It is impossible to ensure that the pressure on the embryos in the circumferential direction is uniform, which will affect the flatness of the embryos and cause deformation of the cigars after placement. Utility Model Content

[0005] The purpose of the utility model is to provide a cigar embryo shaping device to solve the problem in the prior art that the upper and lower mold cores are used to clamp the tobacco embryo, resulting in the concentration of force on the tobacco embryo in the vertical direction and uneven pressure in the circumferential direction, which leads to poor flatness of the tobacco embryo and deformation of the cigar after placement.

[0006] To achieve the above-mentioned purpose, the cigar embryo shaping device in the present invention adopts the following technical solutions:

[0007] A cigar embryo shaping device includes a shaping box, in which a deformable and restorable shaping pipe is provided, one end of the shaping pipe is provided with a smoke inlet connected to the outside of the shaping box, and the other end is provided with a smoke outlet connected to the outside of the shaping box. The shaping box is provided with a pressure medium inlet for filling the shaping box with pressure medium to squeeze the shaping pipe to deform and thereby apply a shaping force to the cigar embryo, and the shaping box is also provided with a pressure medium outlet for discharging the pressure medium in the shaping box to restore the shaping pipe to its original shape.

By filling the shaping pipe with pressure medium to deform it, the pressure medium fills the outer space of the shaping pipe, applying pressure to the shaping pipe over a 360-degree range. This allows the shaping pipe to apply a shaping force to the cigar embryo over a 360-degree range, ensuring uniform pressure on the cigar embryo circumferentially, thereby ensuring the embryo's flatness and preventing deformation after placement. Furthermore, the shaping box is provided with a pressure medium outlet for discharging the pressure medium within the shaping box to restore the shaping pipe to its original shape. Discharging the pressure medium through the pressure medium outlet cancels the compressive effect on the shaping pipe. Since the shaping pipe is deformable and can be restored, the shaping pipe can return to its original shape. This not only facilitates the exit of the cigar embryo from the shaping pipe through the smoke outlet, but also facilitates the next use of the shaping pipe, achieving continuous shaping operations.

[0009] Furthermore, the shaping pipe is arranged vertically, and an openable and closable smoke-blocking valve is provided at the smoke outlet. When the smoke-blocking valve is in a closed state, the cigar embryos entering the shaping pipe are blocked, and when the smoke-blocking valve is in an open state, the shaped cigar embryos are discharged.

[0010] Furthermore, the smoke barrier valve is a ball valve, which includes a valve body fixedly connected to the lower end of the shaped pipe and a ball rotatably installed in the valve body. The ball has a spherical surface for blocking cigar embryos and a through hole for the cigar embryos to pass through.

[0025] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0026] In response to the technical problems existing in the prior art, the basic technical concept of the present invention is to use a deformable and restorable shaping pipe to apply pressure to the cigar embryo, and to set the shaping pipe in a shaping box. By filling the shaping box with a pressure medium, the pressure medium applies pressure to the shaping pipe, causing the shaping pipe to deform, and then applying pressure to the cigar embryo within a 360-degree range, ensuring that the embryo is uniformly pressurized at all points in the circumferential direction, thereby ensuring the flatness of the embryo and avoiding deformation of the cigar after placement.

[0027] Example 1 of the cigar embryo shaping device of the utility model:

[0028] like Figure 1As shown, the cigar embryo shaping equipment includes a shaping box 1, which contains a deformable and restorable shaping channel 2. In one embodiment, the shaping channel 2 can be made of a shape-memory polymer material. This material changes shape in response to external stimuli, retains its deformed state after the stimulus is removed, and reversibly returns to its initial state if the external environment changes again in a specific manner and pattern. During preparation, a section of the shaping channel 2 is prepared using the shape-memory polymer material, with a diameter greater than the diameter of the cigar embryo and a length greater than the length of the cigar embryo. Then, under certain temperature and pressure conditions, the channel is brought into a fixed temporary shape according to the desired cigar type.

[0029] Therefore, in this embodiment, a heater 13 is provided within the shaping box 1 to control the ambient temperature of the shaping pipe 2. During operation, the ambient temperature is maintained within the deformation temperature range of the memory polymer material to ensure that the shaping pipe 2 can deform. Preferably, multiple heaters 13 are provided, each positioned near the inner wall of the shaping box 1. The cigar embryo shaping device also includes a console 7, which is provided with control buttons for controlling the operation of the heater 13. Furthermore, a temperature sensor (not shown) is provided within the shaping box 1. The temperature sensor is used to detect the temperature within the shaping box 1 and transmit the detection data to the console 7. The console 7 is provided with a display screen for displaying the temperature value within the shaping box 1, allowing the operator to control the operation of the heater 13 based on the temperature value.

[0030] In the present invention, one end of the shaping pipe 2 is provided with a smoke inlet connected to the outside of the shaping box 1, and the other end is provided with a smoke outlet connected to the outside of the shaping box 1, so that cigar embryos can be fed into the shaping pipe 2 through the smoke inlet, and the shaped cigar embryos can be discharged through the smoke outlet, thus realizing the feeding and discharging of the embryos. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the smoke inlet and smoke outlet of the shaping pipe 2 are both located inside the shaping box 1, the smoke inlet is connected to a feed pipe 4, and the smoke outlet is connected to a discharge pipe 6, the feed pipe 4 and the discharge pipe 6 respectively pass through the shaping box 1 and extend to the outside of the shaping box 1, and the feed pipe 4 and the discharge pipe 6 are both rigid pipes, which are convenient for feeding and discharging, and ensure that only the shaping pipe 2 is fully and effectively squeezed.

[0031] like Figure 1As shown, the shaping pipe 2 in this embodiment is vertically arranged, and therefore the feed pipe 4 and discharge pipe 6 are also vertically arranged, allowing the cigar embryos to enter and exit the shaping pipe 2 under their own weight. To prevent the entering cigar embryos from being directly discharged through the discharge pipe 6, an openable and closable smoke-blocking valve 3 is provided at the smoke outlet. When the smoke-blocking valve 3 is closed, it blocks the cigar embryos entering the shaping pipe 2, forcing them to remain in the shaping pipe 2 so that the shaping pipe 2 can exert a shaping force on the cigar embryos. When the smoke-blocking valve 3 is open, it allows the shaped cigar embryos to be discharged.

[0032] Furthermore, the smoke barrier valve 3 is a ball valve, which facilitates the switching of the smoke barrier valve 3 between the open state and the closed state. Figure 5 As shown, the smoke barrier valve 3 includes a valve body 3-1 fixedly connected to the lower end of the shaping pipe 2 and a spherical body 3-2 rotatably mounted within the valve body 3-1. The left and right ends of the spherical body 3-2 are rotatably mounted on the valve body 3-1 via left and right bearings 3-3 and 3-4, respectively. The spherical body 3-2 has a spherical surface for blocking cigar embryos and a through hole for passage of the cigar embryos. The through hole is larger than the diameter of the shaped cigar embryos to facilitate smooth passage of the cigar embryos. Furthermore, a gland 3-5 is mounted on the valve body 3-1, and a valve stem 3-6 is connected to the spherical body 3-2. The valve stem 3-6 extends through the gland 3-5 to connect to a drive mechanism. The drive mechanism is preferably powered by a stepper motor. A control button for controlling the stepper motor can be provided on the control console 7 to automatically switch the smoke barrier valve 3 between open and closed states.

[0033] like Figures 1 to 5 As shown, the feed pipe 4 and the shaping pipe 2 are connected by a pipe connector 5, the shaping pipe 2 and the valve body 3-1 are also connected by a pipe connector 5, and the valve body 3-1 and the discharge pipe 6 are also connected by a pipe connector 5. This can prevent the pressure medium in the shaping box 1 from penetrating into the pipe, and at the same time realize the detachable connection between the shaping pipe 2 and the feed pipe 4, and between the shaping pipe 5 and the discharge pipe 6. In this way, different shaping pipes 2 can be prepared according to the different models of cigars produced. In actual production, different shaping pipes 2 can be replaced for different production tasks.

[0034] In the present invention, a pressure medium inlet is provided on the shaping box 1 for filling pressure medium into the shaping box 1 to squeeze the shaping pipe 2 to deform and thereby apply a shaping force to the cigar embryo. By filling the pressure medium to squeeze the shaping pipe 2 to deform, the pressure medium can fill the peripheral space of the shaping pipe 2, apply pressure to the shaping pipe 2 within a range of 360 degrees, and thereby make the shaping pipe 2 apply a shaping force to the cigar embryo within a range of 360 degrees, ensuring that the embryo is uniformly pressurized at all points in the circumferential direction, thereby ensuring the flatness of the embryo and avoiding deformation of the cigar after placement. At the same time, the shaping box 1 is also provided with a pressure medium outlet for discharging the pressure medium in the shaping box 1 so that the shaping pipe 2 can restore its original shape. The pressure medium is discharged through the pressure medium outlet, and the squeezing effect on the shaping pipe 2 is cancelled. Since the shaping pipe 2 is deformable, it can also be restored. In this way, the shaping pipe 2 can be restored to its original shape. On the one hand, it is convenient for the cigarette embryos to be discharged from the shaping pipe 2 through the smoke barrier valve 3 and the discharge pipe 6. On the other hand, it is convenient for the next use of the shaping pipe 2, thereby realizing continuous shaping operation.

[0035] Specifically in this embodiment, Figure 1 As shown, the cigar tobacco blank shaping equipment also includes a hydraulic tank 8 for storing hydraulic oil, a hydraulic pump 9 for pumping the hydraulic oil from the hydraulic tank 8, an oil inlet pipe 11 connected between the outlet of the hydraulic pump 9 and the inlet of the pressure medium, and an oil outlet pipe 12 connected between the pressure medium outlet and the hydraulic tank 8. Brackets are installed at the bottoms of the shaping box 1, the control console 7, and the hydraulic tank 8. The hydraulic pump 9 is used to pump hydraulic oil into the shaping box 1, controlling the hydraulic oil pressure within the shaping box 1 to a certain level, ensuring that the ambient pressure within the shaping box 1 reaches the deformation pressure range of the memory polymer material, thereby ensuring uniform pressure in the shaping pipe 2. After shaping is completed, the hydraulic oil is discharged into the hydraulic tank 8 through the oil outlet pipe 12, enabling oil recycling.

[0036] Furthermore, in this embodiment, a cartridge valve 10 is provided on the hydraulic box 8, the outlet of the hydraulic pump 9 is connected to the cartridge valve 10, and the oil inlet pipe 11 and the oil outlet pipe 12 are also connected to the cartridge valve 10 respectively. The cartridge valve 10 has two working positions, one position is to connect the hydraulic pump 9 and the oil inlet pipe 11, and the other position is to connect the oil outlet pipe 12 and the hydraulic box 8. At the same time, control buttons for controlling the switching position of the cartridge valve 10 and controlling the operation of the hydraulic pump 9 are provided on the console 7, which makes operation more convenient.

[0037] The specific steps of shaping cigar embryos in the utility model of the cigar embryo shaping device are as follows:

[0038] In the first step, cigar tobacco embryos are put into the feed pipe 4. Since the smoke valve 3 is in the closed state ( Figure 2 As shown), the cigarette embryos entering the shaping pipe 2 are stopped by the smoke blocking valve 3.

[0039] In the second step, the heater 13 is started on the control console 7 to raise the temperature in the shaping box 1 to a temperature range within which the memory polymer material undergoes deformation.

[0040] The third step is to switch the position of the cartridge valve 10 on the console 7 and start the hydraulic pump 9, so that the oil in the hydraulic box 8 enters the interior of the shaping box 1 through the oil inlet pipe 11, so that the internal ambient pressure of the shaping box 1 reaches the specified cigar shaping pressure, and the shaping pipe 2 is deformed by pressure ( Figure 3 As shown in the figure), the shaping force is applied to the cigar embryo within a 360-degree range.

[0041] Step 4: After the cigar is shaped, the hydraulic pump 9 is turned off and the position of the cartridge valve 10 is switched so that the high-pressure oil in the shaping box 1 flows into the hydraulic box 8 through the oil outlet pipe 12.

[0042] Step 5: After the high pressure oil is discharged, the shaped pipe 9 returns to its initial state ( Figure 4 As shown), at the same time, the smoke barrier valve 3 is opened, and the cigar embryo enters the next process through the discharge pipe 6.

[0043] In summary, the present invention utilizes hydraulic pressure and a shaping tube made of a shape-memory polymer material to pressurize the cigar embryo. This uniform pressure is applied to the cigar embryo within the shaping tube, significantly improving the flatness of the cigar and preventing deformation after placement. This invention can replace manual labor in the shaping process, saving labor costs and improving work efficiency.

[0044] In other embodiments of the cigar embryo shaping device: a temperature sensor may not be provided in the shaping box, and a display screen is not required on the control console. Instead, a thermometer may be used to perform physical measurements after a period of time.

[0045] In other embodiments of the cigar embryo shaping device, the device may not include a control console, and the control buttons or switches for the heater, hydraulic pump, and smoke barrier valve may be independently and separately located. In other embodiments, the heater may be located within the hydraulic tank. Of course, in other embodiments, the heater may not be required when the ambient temperature is relatively high, such as during the hot summer months.

[0046] In other embodiments of the cigar embryo shaping device, the hydraulic oil stored in the hydraulic tank can be replaced with water, that is, the pressure medium is water. Of course, in other embodiments, the pressure medium can also be air, in which case an air compressor is required to obtain air at a certain pressure. Of course, regardless of the pressure medium used, it is sufficient to reserve a pressure medium inlet and outlet on the shaping tank. During use, the oil inlet, water inlet, air inlet, oil outlet, water outlet, and air outlet pipes can be connected as needed, and the corresponding pump or air compressor can be configured.

[0047] In other embodiments of the cigar embryo shaping device, the shaping pipe and the feed pipe, the discharge pipe and the valve body, or the discharge pipe and the shaping pipe may be fixed by welding or bonding and cannot be disassembled.

[0048] In other embodiments of the cigar tobacco embryo shaping device, both ends of the shaping pipe can be directly extended to the side walls of the shaping box. In this case, there is no need to provide a feeding pipe and a discharging pipe.

[0049] In other embodiments of the cigar embryo shaping device, the shaping pipe can also be arranged horizontally. In this case, a tool can be used to push the cigar embryo into the shaping pipe. Since the cigar embryo can be retained in the shaping pipe by itself, there is no need to provide a smoke-blocking valve. After shaping is completed, the cigar embryo can still be pushed out of the shaping pipe using a tool.

[0050] In other embodiments of the cigar embryo shaping device, the shaping pipe can also be made of shape memory alloy, or of course, can be made of a rubber tube, and the rubber tube can be restored to its original shape by its own elasticity.

[0051] Example 2 of the cigar embryo shaping device of the utility model:

[0052] like Figure 6 As shown, the difference between this embodiment and embodiment 1 lies in the specific structure of the smoke barrier valve. In this embodiment, the smoke barrier valve includes a valve body 14-1 fixedly connected to the lower end of the shaping pipe 2. The valve body 14-1 has a channel 14-2 for the passage of cigar embryos. Two oppositely arranged connecting rods 14-3 are hinged on the inner wall of the channel 14-2. The end of each connecting rod 14-3 is connected to a baffle 14-4, and a telescopic power device 14-5 is connected between each connecting rod 14-3 and the inner wall of the channel 14-2. The telescopic power device 14-5 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. The telescopic power device 14-5 is used to control the swing of the connecting rod 14-3 so that the two baffles 14-4 are close to each other and block the cigar embryos ( Figure 6As shown, the valve body 14-1 and the connecting rods 14-3 are positioned so that the two baffles 14-4 and 14-5 can be moved apart to allow cigar embryos to pass between the two baffles 14-4 and the two connecting rods 14-3. In this embodiment, the connecting rods 14-3 are driven to swing by the telescopic power device 14-5, which in turn drives the baffles 14-4 to block or allow passage of cigar embryos. This simple and easy-to-implement structure allows for easy control. Furthermore, for easier control, a controller 14-6 is mounted on the valve body 14-1 and is controllably connected to the telescopic power device 14-5. This controller 14-6 is also connected to a control console, enabling operation of the telescopic power device 14-5 from the console, further facilitating control. Furthermore, to protect the controller 14-6, a cover plate 14-7 is mounted on the valve body 14-1, with the controller 14-6 located inside the cover plate 14-7.
