Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf processing equipment, in particular to a briquetting device. Background Art

[0002] Tobacco leaves that have undergone threshing and redrying can be briquetized using a briquetting device to produce tobacco leaf samples. Since tobacco leaves need to reach a certain temperature before they can be briquetized, briquetting needs to be performed immediately while the leaves are still warm to avoid the situation where the samples become loose and difficult to shape after briquetting due to the tobacco leaf temperature being too low. However, due to the increasing number of tobacco leaf scientific research experiments being conducted in redrying plants, tobacco leaves collected on the redrying line need to undergo relevant test processing before they can be briquetized. If the temperature of the processed tobacco leaves is too low during briquetting, the tobacco leaf samples will tend to become loose and unshaped after briquetting, and their properties will differ greatly from those of conventional tobacco leaf samples, thus affecting the accuracy of subsequent quality testing and evaluation results.

Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0036] The following combination Figures 1 to 4 , describing the embodiments of the present utility model.

[0037] According to an embodiment of the present invention, a briquetting device is provided, comprising:

[0038] A first heating plate 101;

[0039] The enclosing plate structure 102 is fixedly connected to the first heating plate 101 , and the enclosing plate structure 102 and the first heating plate 101 enclose a receiving cavity 103 ;

[0040] The second heating plate 6 is disposed inside the accommodating chamber 103 and encloses the first heating plate 101 and the enclosure structure 102 to form a compression chamber. The compression chamber is suitable for accommodating materials, and the first heating plate 101 and the second heating plate 6 are suitable for heating the materials.

[0041] The pressing mechanism 2 is disposed on a side of the second heating plate 6 facing away from the first heating plate 101 . The pressing mechanism 2 is adapted to abut against the second heating plate 6 to move the second heating plate 6 in a direction close to the first heating plate 101 .

[0042] The briquetting device provided in this embodiment uses the pressing mechanism 2 to press the second heating plate 6 toward the first heating plate 101 to reduce the volume of the compression chamber, thereby briquetting the material in the compression chamber, and heating the material through the first heating plate 101 and the second heating plate 6 to avoid the material temperature being too low, which may cause the material to become loose and shapeless after being briquetted.

[0043] Specifically, the enclosure structure 102 is formed by enclosing and connecting at least three plates, and a cavity with two openings at both ends is formed inside the enclosure structure 102. As a feasible embodiment, the first heating plate 101 is fixedly connected to the enclosure structure 102 and blocks one end opening of the cavity. The inner wall of the enclosure structure 102 and the main plane of the second heating plate 6 enclose a receiving cavity 103. As an additional embodiment, a fixed plate is fixedly connected to the opening at one end of the enclosure structure 102 to block this opening, thereby constructing a box-shaped structure with one end open. The first heating plate 101 is located in the cavity and fixedly connected to the fixed plate. The inner wall of the enclosure structure 102 and the second heating plate 6, facing away from the main plane of the fixed plate, enclose a receiving cavity 103. The second heating plate 6 is placed into the accommodating cavity 103 through the opening at the other end of the cavity, and the side surface of the second heating plate 6 abuts against the inner wall of the enclosure structure 102 so as to enclose the enclosure structure 102 and the first heating plate 101 to form a compression cavity, wherein there is a gap between the second heating plate 6 and the inner wall of the enclosure structure 102, and the size of this gap allows gas to pass through and can block the passage of materials. As a feasible embodiment, the first heating plate 101 and the second heating plate 6 are configured as plates made of materials such as stainless steel, cast aluminum or carbon fiber, and a resistance wire is provided inside the plate. The resistance wire is energized to generate heat, thereby heating the tobacco leaves. The briquetting device also includes a power cord 5, and the resistance wire is electrically connected to the power cord 5, so that the heating of the first heating plate 101 and the second heating plate 6 can be achieved by plugging and unplugging the power cord 5.

[0044] Taking the compression of tobacco leaves after threshing and redrying as an example, the material selected is tobacco leaves after threshing and redrying. After the tobacco leaves are placed in the accommodating chamber 103, the second heating plate 6 is placed in the accommodating chamber 103 to form a compression chamber that partially overlaps with the accommodating chamber 103. At this time, the tobacco leaves are located in the compression chamber between the first heating plate 101 and the second heating plate 6. The second heating plate 6 is abutted by the pressing mechanism 2 so that the second heating plate 6 moves in the direction close to the first heating plate 101 under the abutting action of the pressing mechanism 2, thereby reducing the volume of the compression chamber and achieving the compression of the tobacco leaves into blocks. The material is heated by the first heating plate 101 and the second heating plate 6 to ensure the temperature of the tobacco leaves and avoid the problem that the tobacco leaves are too low in temperature and are easy to loose and not form after being pressed into blocks. By heating the tobacco leaves, it is beneficial to ensure that the tobacco leaves are not easy to loosen after being compressed into blocks, and block-shaped tobacco leaf samples with the same density as the tobacco leaf sample blocks that have not been tested can be produced, thereby reducing the impact on the accuracy of subsequent related quality inspections and evaluation results.

[0045] In one embodiment, combined Figures 1 to 4 As shown, a temperature controller 3 is provided on the outer side wall of the enclosure structure 102 , and the temperature controller 3 is electrically connected to the first heating plate 101 and the second heating plate 6 respectively to control the heating temperature and heating time of the first heating plate 101 and the second heating plate 6 .

[0046] The briquetting device provided in this embodiment controls the heating temperature and heating time of the first heating plate 101 and the second heating plate 6 through the temperature controller 3, so as to adjust the temperature and time of the material being heated as needed.

[0047] Specifically, a temperature controller 3 is electrically connected between the power cord 5 and the first heating plate 101 and the second heating plate 6. The temperature controller 3 is electrically connected to the power cord 5 and is also electrically connected to the resistance wires of the first heating plate 101 and the second heating plate 6 via two connecting wires 4. This allows the temperature controller 3 to control the heating temperature and heating time of the first heating plate 101 and the second heating plate 6, respectively. A heating cover interface 602 is provided on the side of the second heating plate 6 away from the first heating plate 101. The heating cover interface 602 is electrically connected to the resistance wire inside the second heating plate 6. One of the connecting wires 4 is connected to the heating cover interface 602 to facilitate its installation and removal from the second heating plate 6; the other connecting wire 4 is directly electrically connected to the resistance wire inside the first heating plate 101.

[0048] Additionally, at least one temperature sensor is provided on each of the first heating plate 101 and the second heating plate 6 to detect the temperature of the first heating plate 101 and the second heating plate 6. The temperature controller 3 is electrically connected to the temperature sensor, converts the temperature signal detected by the temperature sensor into a digital signal, and displays the temperature of the first heating plate 101 and the second heating plate 6 on a display screen of the temperature controller 3.

[0049] In one embodiment, combined Figures 1 to 4 As shown, the sides of the first heating plate 101 and the second heating plate 6 that are away from each other are respectively provided with a heat insulation layer.

[0050] The briquetting device provided in this embodiment is provided with a heat insulation layer on the sides of the first heating plate 101 and the second heating plate 6 away from each other to prevent scalding of people around the briquetting device or damage to objects around the briquetting device by high temperature, which is conducive to improving safety of use.

[0051] Specifically, the thermal insulation layer can be provided as an aerogel felt, a rock wool board or a silicate board.

[0052] In one embodiment, combined Figures 1 to 4 As shown, the sides of the first heating plate 101 and the second heating plate 6 that are away from each other are respectively provided with an insulating layer.

[0053] The briquetting device provided in this embodiment is provided with insulating layers on the sides of the first heating plate 101 and the second heating plate 6 that are away from each other, so as to avoid potential safety hazards caused by leakage, thereby improving safety in use.

[0054] Specifically, the insulating layer can be provided as insulating varnish, insulating glue or rubber pad.

[0055] In one embodiment, combined Figures 1 to 4 As shown, an observation window 7 is provided in a local area of ​​the enclosure structure 102 , and a plurality of scale lines 8 are provided on the observation window 7 . The plurality of scale lines 8 are distributed at intervals along the direction from the first heating plate 101 to the second heating plate 6 .

[0056] The briquetting device provided in this embodiment provides an observation window 7 and a scale line 8 on the enclosure structure 102, so that the operator can observe the degree of compression of the material through the observation window 7, so as to promptly stop the pressing mechanism 2 from squeezing the second heating plate 6 after reaching the preset compression degree.

[0057] Specifically, the observation window 7 can be made of transparent glass or a transparent acrylic plate, and the scale line 8 is set on the side of the observation window 7 facing the inside of the accommodating chamber 103, and / or, on the side of the observation window 7 facing the outside of the briquetting device, so that the operator can observe the change in the distance between the second heating plate 6 and the first heating plate 101. Taking compressed tobacco leaves as an example, the direction from the first heating plate 101 to the second heating plate 6 is defined as the first direction. According to the cross-sectional area of ​​the compression chamber perpendicular to the first direction, and the relationship between the weight of the tobacco leaves and the required density of the tobacco leaf briquetting, the length of the tobacco leaf briquetting in the first direction is calculated, and this length is defined as the preset length. The distance between the second heating plate 6 and the first heating plate 101 is observed through the observation window 7 and the scale line 8. When the tobacco leaf briquetting reaches the preset length in the first direction, the pressing mechanism 2 stops squeezing the second heating plate 6.

[0058] In one embodiment, combined Figures 1 to 4 As shown, the pressing mechanism 2 includes a bracket 201 fixedly connected to the enclosure structure 102 , and a screw 202 is threadedly connected to the bracket 201 . The screw 202 is suitable for rotating around its own axis to move in a direction close to the first heating plate 101 .

[0059] The briquetting device provided in this embodiment rotates the screw 202 so that the screw 202 can press the second heating plate 6 toward the first heating plate 101 under the action of the thread, which is conducive to improving the convenience of operation.

[0060] Specifically, the bracket 201 can be a U-shaped plate or a flat plate. A threaded hole is provided on the bracket 201, and the screw 202 is threadedly connected to the threaded hole. The axial direction of the screw is parallel to the direction of the second heating plate 6 toward the first heating plate 101. The screw 202 is rotated so that it moves in a direction close to the first heating plate 101 under the action of the thread. The screw 202 gradually approaches the second heating plate 6 and continues to squeeze the second heating plate 6 after contacting the second heating plate 6, so that the second heating plate 6 moves in a direction close to the first heating plate 101, thereby reducing the space of the compression chamber and compressing the material inside the compression chamber. When the material is compressed into place, the screw 202 is stopped to stop further compression of the material block.

[0061] At least part of the screw 202 is located on the side of the bracket 201 away from the second heating plate 6. A handle 203 is fixedly connected to the screw 202. The handle 203 is located on the side of the bracket 201 away from the second heating plate 6. The handle 203 is constructed in a rod shape. Preferably, the axis of the rod-shaped handle 203 is perpendicular to the axis of the screw 202, so that the operator can drive the screw 202 to rotate around its own axis by holding the handle 203, thereby improving the convenience of operation.

[0062] In one embodiment, combined Figures 1 to 4 As shown, an abutment groove 601 is provided on the side of the second heating plate 6 facing away from the first heating plate 101 , and the abutment groove 601 corresponds to the end of the screw 202 close to the second heating plate 6 .

[0063] In the briquetting device provided in this embodiment, the abutment groove 601 corresponds to one end of the screw 202 facing the second heating plate 6, so that when the screw 202 approaches the second heating plate 6 and abuts against the second heating plate 6, one end of the screw 202 falls into the abutment groove 601, thereby improving the abutment stability of the screw 202 and the second heating plate 6.

[0064] Specifically, one end of the screw 202 abuts against the inner wall of the abutment groove 601 to enhance the abutment stability of the screw 202 when abutting the second heating plate 6. Furthermore, a pressure head 2021 is provided at one end of the screw 202 close to the second heating plate 6. As a feasible embodiment, the pressure head 2021 is constructed in a spherical or hemispherical shape, and the side of the pressure head 2021 facing the second heating plate 6 is an arc surface. In this case, the inner wall of the abutment groove 601 is an arc-shaped inner wall and is compatible with the pressure head 2021. As an additional embodiment, the pressure head 2021 is constructed in a cylindrical shape, and the axis of the cylinder coincides with the axis of the screw 202. In this case, the inner wall of the abutment groove 601 is a cylindrical inner wall, and the inner diameter of the cylindrical inner wall is compatible with the diameter of the cylindrical pressure head 2021. The insulating layer and the heat-insulating layer are provided with clearance holes at positions corresponding to the abutting groove 601 , so that one end of the screw 202 gradually approaches the second heating plate 6 and abuts against the abutting groove 601 to form a clearance.

[0065] In one embodiment, combined Figures 1 to 4 As shown, an opening is formed on one side of the enclosure structure 102 corresponding to the accommodating cavity 103 , and the briquetting device further includes a sealing plate 9 , which has a first state of blocking the opening and a second state of exposing the opening.

[0066] The briquetting device provided in this embodiment places the sealing plate 9 in the second state so that the compression chamber is connected to the outside through the opening, thereby facilitating the material to enter and exit the compression chamber through the opening; and places the sealing plate 9 in the first state so that the compression chamber is in a closed state, thereby facilitating the compression operation of the material.

[0067] Specifically, when the sealing plate 9 is in the first state, the material is compressed; when the compression is complete, the sealing plate 9 is placed in the second state, and the compressed material block can be removed through the opening. The sealing plate 9 can be detachably connected to the enclosure structure 102 at the opening via bolts, so that the sealing plate 9 can be switched between the first and second states by disassembling and assembling the sealing plate 9. Alternatively, the sealing plate 9 can be switched between the first and second states by hingedly connecting one side of the sealing plate 9 to the enclosure structure 102 and snapping the other side of the sealing plate 9 to the enclosure structure 102.

[0068] In one embodiment, combined Figures 1 to 4 As shown, one side of the sealing plate 9 is hinged to the enclosure structure 102 , and the other side is clamped to the enclosure structure 102 .

[0069] In the briquetting device provided in this embodiment, both sides of the sealing plate 9 are hinged and clamped to the enclosure structure 102 respectively, so that the sealing plate 9 can be switched between the first state and the second state, which is conducive to improving the convenience of operation.

[0070] Specifically, one side of the sealing plate 9 is hinged to the enclosure structure 102, and the other side is provided with a buckle 1001. The enclosure structure 102 is provided with a base 1002 at the position corresponding to the buckle 1001. The buckle 1001 and the base 1002 are constructed in the form of a buckle (for example, a stainless steel flat-mouth buckle). When the sealing plate 9 is rotated to a position that fits the enclosure structure 102, the buckle 1001 is engaged with the base 1002, so that the sealing plate 9 is in the first state; when it is necessary to expose the opening, the buckle 1001 is operated to disengage the base 1002, and the sealing plate 9 is rotated in a direction away from the accommodating chamber 103, thereby exposing the material block in the compression chamber and allowing the material block to be separated from the briquetting device through the opening.

[0071] In one embodiment, combined Figures 1 to 4As shown, the briquetting device also includes a support plate 11, which is located below the material to be suitable for carrying the material; the support plate 11 has an embedded state in the accommodating cavity 103, and a detached state in which it detaches from the accommodating cavity 103 through the opening when the sealing plate 9 is in the second state.

[0072] The briquetting device provided in this embodiment is provided with a support plate 11 below the material, so that when the material is taken out after being compressed, the material block is supported by the support plate 11, thereby completely taking out the compressed material block.

[0073] Specifically, the support plate 11 is disposed within the accommodating chamber 103 to accommodate the material. After the material is compressed, the sealing plate 9 is placed in the second state, and the support plate 11 is moved to disengage the accommodating chamber 103 at the opening. During this process, the material block is supported by the support plate 11, thereby facilitating stability when the material block is removed. As a preferred embodiment, the opening is located on the side of the briquetting device along the direction of gravity, and a pull ring 1101 is provided on the support plate 11. After the sealing plate 9 is exposed from the opening, the pull ring 1101 is used to pull the support plate 11 and the material block out of the opening, thereby completely detaching the material block from the compression chamber, avoiding direct external force on the material block, thereby damaging the integrity of the material block, and facilitating improved operational convenience.

[0074] Obviously, the above embodiments are merely examples for the purpose of clarity of explanation and are not intended to limit the implementation methods. Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the present invention.
