[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Please refer to Figure 1-3 , Figure 1 A front structural schematic diagram of an embodiment of a horizontal straw pelletizing machine provided by the utility model; Figure 2 A schematic diagram of the back structure of an embodiment of a horizontal straw pelletizing machine provided by the utility model; Figure 3 The present invention is a schematic diagram of the compression chamber structure of an embodiment of a horizontal straw pelletizing machine provided by the utility model.

[0031] In a specific embodiment, the horizontal straw pelletizing machine comprises:

[0032] A feed port 10 is used to receive the fermented raw materials entering the feed hopper;

[0033] A material conveying device 20, used to convey the raw materials from the feed hopper to the working area;

[0034] The mold compression chamber 30 extrude the raw material delivered to the working area by the material conveying device 20 through the eccentric roller structure. As the amount of the raw material increases, the distance between the eccentric roller structure and the mold 6 decreases, the raw material undergoes irreversible deformation, and the density increases. Through the eccentric action of the eccentric shaft 5 of the eccentric roller structure, the gap between the rollers 3 decreases, and the extrusion pressure increases. After the material density of the raw material reaches a threshold, it enters the mold hole of the mold 6 under the action of the extrusion force and is extruded from the mold hole to form a product.

[0035] The feed port 10 is used to receive the fermented raw materials entering the feed hopper; the material conveying device 20 is used to convey the raw materials from the feed hopper to the working area; the mold compression chamber 30 extrude the raw materials conveyed to the working area by the spiral feeding mechanism through the eccentric roller structure. As the raw materials increase, the distance between the eccentric roller structure and the mold 6 decreases, the raw materials undergo irreversible deformation, and the density increases. Through the eccentric action of the eccentric shaft 5 of the eccentric roller structure, the gap between the rollers 3 is reduced, and the extrusion pressure increases. After the material density of the raw materials reaches the threshold, they enter the mold hole of the mold 6 under the action of the extrusion force and are extruded from the mold hole to form a product. The roller 3 adopts an eccentric roller structure with good molding quality, high efficiency, low price, low power consumption, and simple operation. The mold 6 roller wears synchronously, which meets the needs of long-term uninterrupted production and reduces maintenance costs and maintenance time.

[0036] In order to improve the adjustment of product size, in one embodiment, the horizontal straw pelletizer also includes a gap adjustment plate 4 arranged in the compression chamber 30 of the mold 6, which is used to adjust the gap between the pressure rollers 3 between the double rollers of the eccentric pressure roller structure to achieve adjustment of the length of the output material.

[0037] By adjusting the gap between the two rollers of the eccentric roller structure, the timing of reaching the extrusion threshold during the rotation process is different. For example, before the adjustment, 10 volumes of material are required to reach the extrusion output condition. If the gap between the rollers 3 is increased, the distance from the mold 6 will be reduced, and only less raw material is needed to achieve discharge. It may take 7-8 volumes of material to reach the extrusion output condition. On the contrary, if the gap between the rollers 3 is reduced, more material is required for output.

[0038] In the present application, the product length is adjusted by reducing the gap between the pressing rollers 3 .

[0039] In order to improve the stability and reliability of the product, in one embodiment, the horizontal straw pelletizer also includes a connecting plate 2 connecting the double rollers of the eccentric pressing roller 3 structure, the connecting plate 2 is located on the side of the double rollers of the eccentric pressing roller 3 structure, and is connected to the fixed axis of the double rollers of the eccentric pressing roller structure, and the gap adjustment plate 4 is located on the surface of the connecting plate 2.

[0040] By setting the connecting plate 2, external interference to the double rollers is reduced, the reliability of use is improved, and the efficiency of the raw materials entering the mold 6 is also improved.

[0041] The present application does not limit the structure and connection method of the connecting plate 2.

[0042] In order to improve the operation monitoring of the device, in one embodiment, the horizontal straw pelletizer also includes a display connected to the gap adjustment plate 4, the heating device, and the temperature detection device, which is used to display the current gap between the pressure rollers 3, the heating power of the heating device, and the temperature value obtained by the temperature detection device.

[0043] The display shows the current gap between the pressing rollers 3, the heating power of the heating device, and the temperature value obtained by the temperature detection device, and displays the operating parameters in real time, thereby improving management efficiency.

[0044] In order to further improve the subsequent extrusion effect, in one embodiment, the horizontal straw pelletizer also includes a heating device arranged at the feed port 10, which is used to heat the fermented raw materials entering the feed hopper to a predetermined temperature, and the heating device is a microwave heating device, an electromagnetic heating device or a water bath heating device.

[0045] By preheating the raw materials and increasing the temperature of subsequent extrusion, the hardness of the raw materials is reduced and the extrusion efficiency is improved.

[0046] The present application does not limit the heating device, including but not limited to microwave heating device, electromagnetic heating device or water bath heating device.

[0047] Furthermore, in order to improve the control of temperature, in one embodiment, the horizontal straw pelletizer also includes a temperature detection device arranged at the feed port 10, which is used to measure the temperature value of the fermented raw material entering the feed hopper and feed the temperature value back to the heating device.

[0048] The temperature value of the fermented raw material entering the feed hopper is measured by a temperature detection device, and the temperature value is fed back to the heating device, so as to realize temperature detection and feedback, ensure that the temperature is heated to a specified value, and improve the accuracy of heating.

[0049] The present application does not limit the type of temperature detection device, and it can be implemented using an infrared sensor or other sensors.

[0050] Since the length of the above-mentioned product output may be uncertain, affecting the quality of the product, in order to solve this problem, in one embodiment, the horizontal straw pelletizer also includes a binder output device arranged in the feed hopper, which is used to add adhesive to the raw material, increase the continuity and output length of the product output, and cut the product to a preset length through the linear motion of the cutter.

[0051] Adhesive is added to the raw material through an adhesive output device to increase the continuity and length of product output, and a cutter is arranged at the outlet. The cutter moves linearly to cut the product to a preset length, thereby improving the accuracy of the product.

[0052] The present application does not limit the type and state of the adhesive, which may be solid or liquid, and the cutter may be a rotating structure or a structure that moves up and down.

[0053] In the present application, a material conveying device 20 is used for material transmission, and its structure is not limited. The material conveying device 20 is a screw feeding mechanism or a belt feeding mechanism. The screw feeding mechanism is used to drive the raw material from the feed hopper to the working area by rotation, or the belt feeding mechanism is used to drive the raw material from the feed hopper to the working area by rotation of the belt.

[0054] Since the screw feeding mechanism is used to transport materials, it also has the effect of stirring and mixing the materials, thereby improving the subsequent extrusion effect. Therefore, the screw feeding mechanism is generally used.

[0055] In order to further protect the device and prevent dust from entering, in one embodiment, the horizontal straw pelletizing machine also includes an outer cover 1 arranged outside the compression chamber 30 of the mold 6, the mold 6 is arranged on the periphery of the eccentric roller structure, the outer cover 1 is arranged on the periphery of the mold 6, and the outer cover 1 includes a discharge port 60 for outputting the product extruded from the mold hole.

[0056] The outer cover 1 is used to protect the relevant components, reduce the entry of impurities, and improve the quality of the product. There is no limitation on the connection method, and the connection method such as clamping, bolting, etc. can be adopted.

[0057] Furthermore, in order to reduce the impact of vibration on reliability during equipment operation, in one embodiment, the horizontal straw pelletizer also includes an operating platform 40 for supporting the feed hopper, the material conveying device 20, and the mold compression chamber 30, the feed hopper is located at the left end of the operating platform 40, the mold compression chamber 30 is located at the right end of the operating platform 40, the material conveying device 20 is horizontally connected to the feed hopper and the mold 6 compression chamber 30, and the feed port 10 is located at the top of the feed hopper.

[0058] The present application does not limit the type and size of the operating platform 40 .

[0059] It should be pointed out that when the material in this application enters unevenly or the material is insufficient, it will not affect the continuity of the discharge. Only when the material is filled into the compression chamber and reaches a certain amount, will sufficient extrusion pressure be formed to extrude the straw powder into shape.

[0060] The output length of the product in this application is related to the type of straw, degree of crushing, moisture content, compression chamber area, die hole size, etc., but the output length of the product will not be long, and the length difference is not large. It is granular and does not require a cutter.

[0061] Since the material is discharged in a free-fall state, a rotating cutter is provided at the discharge port 60. When the product is not supported and fixed, the cutter will break up or knock the product away again. By adding adhesive to the raw material, the continuity and length of the product output are increased, and a cutter is provided at the outlet. The cutter moves in a straight line to cut the product to a standard length.

[0062] In one embodiment, the working process of the horizontal straw pelletizer is as follows:

[0063] The main shaft of the pressing roller 3 is driven by the motor 50, which drives the pressing roller 3 on the eccentric shaft 5 to rotate clockwise at a certain speed. The fermented raw materials are first heated by microwaves in the machine feed hopper, and then enter the working area between the mold 6 and the pressing roller 3 through the spiral feeding mechanism. Under the friction between the mold 6, the working gap between the pressing roller 3 and the material, the pressing roller 3 begins to rotate. As the main shaft rotates, the pressing roller 3 revolves around the main shaft and also rotates around the eccentric shaft 5 of the pressing roller 3. When the material is continuously fed into the compression chamber, the extrusion force continues to increase. When it increases to a level sufficient to overcome the friction between the material in the die hole and the inner wall, the material is squeezed into the die hole. As the pressing roller 3 rotates continuously, the material in the die hole of the mold 6 breaks under the action of gravity, forming a cylindrical granular product, which falls into the discharge port 60.

[0064] According to the different positions of the material in the entire molding process, the material is roughly divided into three areas, namely the feeding area, the extrusion deformation area and the molding area.

[0065] 1) Feeding area: A microwave heating device is installed at the feeding port. Under the action of the spiral feeding mechanism, the material is horizontally transported to the compression chamber of the mold. At this time, the material density is relatively small.

[0066] 2) Extrusion deformation zone: As the roller rotates, the material enters the extrusion zone. The material continues to increase, the space between the mold and the roller continues to decrease, the gap between the powders gradually decreases, the material gradually compacts, the material undergoes irreversible deformation, and the density gradually increases.

[0067] 3) Extrusion molding area: In the extrusion molding area, due to the effect of the eccentric shaft, the gap between the pressure rollers is sharply reduced, the extrusion pressure is sharply increased, the material density is further increased, and the material enters the die hole under the action of the extrusion force until it is extruded from the die hole.

[0068] The pressing roller adopts an eccentric pressing roller structure, which has good molding quality, high efficiency and adjustable compression gap; the feed hopper is also a microwave heating cavity, which can heat the raw materials to a suitable temperature to make molding easier; the structure is simple and practical.

[0069] To sum up, the horizontal straw pelletizing machine provided by the embodiment of the utility model has a feed port for receiving the fermented raw materials entering the feed hopper; the material conveying device is used to convey the raw materials from the feed hopper to the working area; the mold compression chamber extrude the raw materials conveyed to the working area by the spiral feeding mechanism through the eccentric roller structure. As the raw materials increase, the distance between the eccentric roller structure and the mold decreases, the raw materials undergo irreversible deformation, and the density increases. Through the eccentric action of the eccentric shaft of the eccentric roller structure, the roller gap decreases, the extrusion pressure increases, and after the material density of the raw materials reaches the threshold, they enter the mold hole of the mold under the action of the extrusion force and are extruded from the mold hole to form a product. The roller adopts an eccentric roller structure, which has good molding quality, high efficiency, low price, low power consumption, simple operation, and synchronous wear of the mold rollers, which meets the needs of long-term uninterrupted production and reduces maintenance costs and maintenance time.
