Description

Technical Field

[0001] This utility model relates to the field of material processing and molding technology, and in particular to a flat die granulator. Background Technology

[0002] In the field of material processing, the forming of powdered materials has always been a critical task. Traditional material forming methods have many limitations, making it difficult to efficiently and accurately transform powdered materials into granular products of specific shapes and specifications. With the development of industrial production, the demand for granular products is increasing, requiring not only large output but also higher requirements for granule quality and dimensional consistency. Against this backdrop, flat die granulators have emerged, providing an efficient and flexible solution for the forming and processing of powdered materials.

[0003] However, existing flat die pellet mills generally suffer from a large footprint. Their overall structural design is not compact enough, and the layout of core components such as conical pressure rollers, molds, cutters, and material conveying systems lacks optimization, resulting in an overall large size of the equipment. This not only increases the cost of occupying production space but also places higher demands on the space planning of production workshops. Especially in small and medium-sized production scenarios with limited space, it is difficult to deploy flexibly, limiting its application in environments with scarce space resources.

[0004] Secondly, insufficient granulation strength is another prominent problem with existing equipment. Due to limitations in the fitting precision of the pressure rollers and the die, as well as the pressure transmission mechanism, the material is subjected to insufficient and uneven pressure during extrusion molding, resulting in low internal density of the produced columnar granules. This directly leads to weak mechanical strength of the granules, making them prone to breakage and pulverization during subsequent storage, transportation, and use, thus affecting the overall quality and performance of the product. Utility Model Content

[0005] The purpose of this invention is to solve the problems of excessive floor space and insufficient granulation strength in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flat die granulator, comprising: a worktable; a reducer housing, fixedly installed on the upper end of the worktable, and connected to a circulating oil pump via a coupling; a shock-absorbing support, fixedly installed on the upper end of the worktable, with a crushing component disposed on its upper end; a feeding component, installed at the lower end of the crushing component; and a discharge chamber, disposed at the lower end of the crushing component, with a pushing component disposed inside, and a cutting component disposed on one side of the pushing component; wherein the feeding component, the crushing component, and the discharge chamber are interconnected.

[0007] The technical advantages of adopting the above-mentioned further solutions are: through the compact connection of each component, the use of circulating oil pump for lubrication and shock-absorbing supports for stabilization, the feeding, crushing and granulation are carried out in a continuous manner, achieving efficient operation, reducing the footprint and maintenance costs, and ensuring granulation quality.

[0008] In a preferred embodiment, the crushing assembly includes: a crushing chamber disposed at the upper end of the worktable; multiple sets of conical crushing rollers arranged in a circular array inside the crushing chamber; and a connecting shaft fixedly connected to the end of the conical crushing rollers, with one end penetrating through the outer wall of the crushing chamber and connected to a drive motor.

[0009] The technical effect of adopting the above-mentioned further solution is that multiple sets of conical crushing rollers are distributed in a ring array in the crushing chamber and are driven synchronously by the drive motor through the connecting shaft, which increases the contact surface with the raw materials, efficiently crushes the materials, provides uniform raw materials for subsequent granulation, and improves the overall granulation effect and efficiency.

[0010] In a preferred embodiment, the feeding assembly includes: a feeding hopper, which is connected above the crushing chamber and has a cover on its upper end; a stirring shaft, which is movably disposed inside the feeding hopper and has one end passing through the cover and connected to a rotary motor; and multiple stirring columns, which are fixedly connected to the outside of the stirring shaft.

[0011] The technical effect of adopting the above-mentioned further solution is that the rotary motor drives the stirring shaft and multiple sets of stirring columns to rotate, which can prevent the raw materials from clumping and blocking, allowing the raw materials to fall evenly into the crushing chamber, ensuring smooth feeding, providing a stable supply of raw materials for subsequent crushing and granulation, and improving overall efficiency.

[0012] In a preferred embodiment, the feeding assembly further includes: a fixed plate, fixedly connected to the lower port of the feeding hopper; and a movable plate, fixedly connected to the bottom of the stirring shaft; wherein the movable plate and the fixed plate are the same size and shape.

[0013] The technical advantages of adopting the above-mentioned further solution are: the fixed plate and the movable plate are the same size and shape, the movable plate rotates with the stirring shaft, the overlap can be controlled by the angle change, the material dropping efficiency can be maximized or the dropping can be stopped, the feeding amount can be precisely adjusted, the stability of subsequent processes can be ensured, and the granulation effect can be improved.

[0014] In a preferred embodiment, the pushing assembly includes: a discharge trough disposed inside the discharge chamber; a stop plate movably installed inside the discharge trough; and a first telescopic rod, one end of which is fixedly connected to the stop plate, and the other end of which passes through the side wall of the discharge chamber and is connected to a first hydraulic shaft.

[0015] The technical effect of adopting the above-mentioned further solution is that the first hydraulic shaft drives the first telescopic rod, which drives the abutment plate to move in the discharge trough, which can stably push the material, provide continuous power for subsequent cutting, ensure that the material enters the cutting process evenly, ensure the continuity of granulation and the quality of granule forming, and improve granulation efficiency.

[0016] In a preferred embodiment, the cutting assembly includes: a grinding disc, movably mounted in a discharge port that extends through the side wall of the discharge chamber; multiple grinding holes that extend through the surface of the grinding disc; and a cutter, movably mounted in a cutter groove on the upper surface of the discharge chamber.

[0017] The technical effect of adopting the above-mentioned further solution is that the multiple grinding holes of the grinding disc allow the material to form strips, and the cutter moves in the cutting groove to cut the strip material at regular lengths on one side of the grinding disc, ensuring uniform particle shape and length, improving granulation regularity, and facilitating subsequent collection and use.

[0018] In a preferred embodiment, the cutting assembly further includes: a second telescopic rod, fixedly connected to the upper end of the cutter; and a second hydraulic shaft, mounted on the other end of the second telescopic rod.

[0019] The technical advantage of adopting the above-mentioned further solution is that the second hydraulic shaft drives the second telescopic rod, causing the cutter to move up and down regularly within the cutter groove, precisely executing the cutting action. The cutting rhythm can be controlled by adjusting the operating frequency of the hydraulic shaft, flexibly changing the particle length to ensure uniform cutting and improve granulation adaptability and quality.

[0020] In a preferred embodiment, the flat die granulator further includes: a feeding block, symmetrically installed on the left and right sides of the discharge trough; and a discharge pipe, connected to one side of the discharge port outside the discharge chamber.

[0021] The technical advantages of adopting the above-mentioned further solution are as follows: the feed blocks are symmetrically installed on both sides of the discharge chute, which can guide the crushed material into the discharge chute accurately, ensuring continuous subsequent granulation. The discharge pipe is connected to the outside of the discharge port, which facilitates the rapid collection of the granulated particles, reduces material residue and scattering, and improves the overall process smoothness and collection efficiency.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. This utility model, through its integrated structural design, compactly integrates the feeding component, crushing component, pushing component, and cutting component onto a workbench. All components are connected via internal channels, eliminating the need for additional connecting pipes and significantly reducing the overall footprint. Simultaneously, the components work together to form a continuous production process: during feeding, the stirring shaft drives the stirring column to prevent raw material agglomeration, while the moving and fixed blades precisely control the feeding speed to avoid material accumulation or interruption; in the crushing stage, multiple sets of conical crushing rollers are arranged in a circular array to simultaneously crush the raw material, greatly improving pre-processing efficiency; in the granulation stage, the first telescopic rod of the pushing component pushes the abutment plate for continuous feeding, while the second telescopic rod of the cutting component drives the cutter to cut regularly, achieving efficient material flow from input to forming, effectively increasing granulation output per unit time.

[0024] 2.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1:

[0036] Please see Figures 1-6 This embodiment provides a flat die granulator that can achieve efficient crushing of raw materials. The specific concept is as follows:

[0037] A flat die pellet mill includes: a worktable 1, a reducer housing 2 and a circulating oil pump 3. The flat die pellet mill also includes: a shock-absorbing support 4 and a crushing component.

[0038] Among them, the workbench 1, which serves as the main support structure, has a reducer housing 2 fixedly installed on its top.

[0039] The reducer housing 2 is linked to the circulating oil pump 3 via a coupling, providing stable power transmission and lubrication for equipment operation.

[0040] Secondly, the upper end of the workbench 1 is also equipped with a shock-absorbing support 4, which supports the crushing components on top. The shock-absorbing design can reduce the vibration and noise during the operation of the equipment.

[0041] As some examples, in this embodiment, the crushing assembly includes: a crushing chamber 12, a conical crushing roller 13, a connecting shaft 14, and a drive motor 15.

[0042] The conical crushing rollers 13 are distributed in a ring array inside the crushing chamber 12.

[0043] In addition, the end of the conical crushing roller 13 passes through the outer wall of the crushing chamber 12 via the connecting shaft 14, forming a transmission connection with the drive motor 15.

[0044] It should be noted that the reducer in this embodiment is a horizontal special reducer, and the motor power is 45kw.

[0045] In this embodiment, after the feeding assembly sends the raw material into the crushing chamber 12, the drive motor 15 drives multiple sets of conical crushing rollers 13 to rotate synchronously through the connecting shaft 14 to crush the raw material.

[0046] Example 2:

[0047] Please see Figures 1-6 Based on Example 1, this example provides a flat die granulator that can achieve efficient raw material conveying. The specific concept is as follows:

[0048] The flat die pellet mill also includes a feeding assembly and a discharge chamber 16.

[0049] The crushing component is connected to the feeding component and the discharge chamber 16 in sequence below. The three are interconnected through internal channels to form a complete material flow path from raw material input to granulation output.

[0050] As examples, in this embodiment, the feeding assembly includes: a feeding hopper 5, a cover 6, a stirring shaft 7, a stirring column 8, a rotary motor 9, a movable plate 10, and a fixed plate 11.

[0051] The hopper 5 is located above the crushing chamber 12, and its upper end is covered by a cover 6.

[0052] In addition, the hopper 5 is equipped with a stirring shaft 7.

[0053] Among them, multiple sets of stirring columns 8 are fixed to the outside of the stirring shaft 7.

[0054] The top of the stirring shaft 7 passes through the cover 6 and is connected to the rotary motor 9.

[0055] In addition, a fixed plate 11 is fixed at the lower end of the hopper 5, and a movable plate 10 is installed at the bottom of the stirring shaft 7. The two are perfectly matched in shape and size.

[0056] It should be noted that when the rotary motor 9 drives the stirring shaft 7 to rotate, the movable plate 10 rotates with the shaft: when it is completely overlapped with the fixed plate 11, the feeding channel is fully open and the material falls at the fastest speed; when it is completely offset, the channel is closed and the material conveying is suspended.

[0057] In this embodiment, the rotation of the stirring column 8 can prevent the raw materials from clumping and clogging, and the cooperation between the movable plate 10 and the fixed plate 11 can precisely control the amount of material fed, improve the crushing effect of the conical crushing roller 13, and provide high-quality pre-treated materials for subsequent granulation.

[0058] Example 3:

[0059] Please see Figures 1-6 Based on Example 1, this example provides a flat die granulator with granulation and molding effect, the specific idea of ​​which is as follows:

[0060] The flat die pellet mill also includes a feeding assembly and a cutting assembly.

[0061] The material pushing component is located inside the discharge chamber 16, while the cutting component is located on one side of the material pushing component.

[0062] As examples, in this embodiment, the material pushing assembly includes: a discharge chute 18, a stop plate 19, a first telescopic rod 20, and a first hydraulic shaft 21.

[0063] Among them, the abutment plate 19 is movably placed inside the discharge trough 18.

[0064] One side of the abutment 19 is connected to the first telescopic rod 20.

[0065] In addition, the other end of the first telescopic rod 20 passes through the side wall of the discharge chamber 16 and is connected to the first hydraulic shaft 21.

[0066] It should be noted that feeding blocks 17 are symmetrically installed on the left and right sides of the discharge chute 18, which can guide the crushed material into the chute.

[0067] As examples, in this embodiment, the cutting assembly includes: a grinding disc 23, a grinding hole 24, a cutting blade 26, a second telescopic rod 29, and a second hydraulic shaft 28.

[0068] The grinding disc 23 is installed inside the discharge port 22 on the side wall of the discharge chamber 16, and multiple sets of through grinding holes 24 are opened on its surface.

[0069] The cutter 26 is placed in the cutter groove 27 at the upper end of the discharge chamber 16, located on one side of the grinding disc 23.

[0070] In addition, the top of the cutter 26 is connected to the second hydraulic shaft 28 via the second telescopic rod 29.

[0071] It should be noted that the discharge port 22 is externally connected to the discharge pipe 25 for collecting finished particles.

[0072] In this embodiment, the hydraulic drive of the feeding assembly ensures stable material forming pressure, the grinding hole 24 ensures consistent particle shape, and the regular movement of the cutter 26 makes the particle length uniform, thus improving the overall granulation quality and production efficiency.

[0073] Working principle: This equipment is a flat die granulator. In use, first open the cover 6 of the feeding hopper 5, pour the raw material to be processed into the feeding hopper 5, and then close the cover 6. Start the rotary motor 9 to drive the stirring shaft 7 and the external stirring column 8 to rotate, preventing the raw material from clumping. By adjusting the speed of the rotary motor 9, the overlap between the moving plate 10 and the fixed plate 11 is controlled, and the feeding speed is adjusted to ensure that the raw material enters the crushing chamber 12 evenly.

[0074] When the raw material enters the crushing chamber 12, the drive motor 15 is started, which drives multiple sets of conical crushing rollers 13 to rotate synchronously through the connecting shaft 14 to crush the raw material. The crushed material enters the discharge chute 18 under the guidance of the feed block 17. At this time, the first hydraulic shaft 21 is started, and the first telescopic rod 20 pushes the abutment plate 19 to squeeze the material towards the discharge port 22.

[0075] The material is compressed to the grinding disc 23 and formed into strips through the grinding holes 24. Simultaneously, the second hydraulic shaft 28 is activated, and the second telescopic rod 29 drives the cutter 26 to move rhythmically up and down within the cutting groove 27, cutting the strip-shaped material into equal-length particles. The cut particles are collected through the discharge pipe 25.

[0076] During operation, if it is necessary to pause feeding, the rotary motor 9 can be adjusted to completely offset the moving plate 10 from the fixed plate 11; if it is necessary to adjust the particle length, the operating frequency of the second hydraulic shaft 28 can be changed. After the work is completed, turn off each motor and hydraulic shaft in sequence, clean the residual material in the feeding hopper 5, crushing chamber 12 and discharge chamber 16 to ensure that the equipment is clean for the next use.

[0077] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
