Description

Technical Field

[0001] This utility model relates to the field of raw material processing equipment technology, and in particular to a raw material crushing mechanism. Background Technology

[0002] Currently, the equipment used for raw material crushing in the food industry is still mainly traditional impact crushers. Their core working principle is to apply impact force to the raw materials through the reciprocating linear motion of the crushing blocks to achieve crushing. For example, the "Raw Material Crushing Device for Food Processing" application number 202020184128.9 includes a support frame with feet at the four corners of the bottom. Brake wheels are installed at the bottom of the feet. A cylinder is located between the two sides of the support frame, rotatably connected to it. A bottom cover is installed at the bottom of the cylinder. A lifting box is fixedly connected to the top of the support frame. A second motor is fixedly connected to the inner wall of one side of the lifting box. A bracket is installed at one end of the second motor, and a rotating frame is installed at the end of the bracket away from the second motor. A first bearing is located in the middle of the rotating frame, and a hammer rod is rotatably connected to the bottom of the first bearing. A hammer head is installed at the bottom of the hammer rod. During operation, the second motor drives the rotating frame to rotate, which in turn drives the hammer rod to move up and down, causing the hammer head to reciprocate and impact the raw materials inside the cylinder, achieving the purpose of crushing the raw materials. This achieves a certain degree of labor saving and improves the practicality and crushing efficiency of the entire device.

[0003] However, existing technologies based on a single reciprocating impact motion have the following drawbacks when processing various food ingredients. When the hammer (i.e., the tamping block) impacts downwards, in addition to crushing the ingredients directly below, it also squeezes some of the ingredients at the bottom towards the periphery. Because the cylinder of the device has a relatively fixed structure, the squeezed ingredients gradually accumulate near the inner wall of the cylinder. The hammer's movement trajectory is limited to a reciprocating motion along the cylinder's axis, restricting its effective range to the central area of ​​the cylinder and failing to impact the accumulated ingredients near the inner wall, making it difficult to effectively impact these accumulated ingredients. Utility Model Content

[0004] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a raw material crushing mechanism, comprising:

[0005] A container module, the container module including a container that holds a limited amount of raw materials;

[0006] The material tamping module includes a hammer and a spiral scraper, the spiral scraper being wound around the outside of the hammer and in contact with the inner wall of the container;

[0007] The third power device drives the hammer head to move vertically.

[0008] The second power unit drives the spiral scraper to rotate around its own circumference.

[0009] This invention features a spiral scraper surrounding the outside of the hammerhead, which is driven by a second power device to rotate around its circumference. When the hammerhead moves vertically under the drive of a third power device to impact and crush the material, the rotating spiral scraper can scrape off the raw material adhering to the inner wall of the container. The spiral structure then transports the raw material accumulated near the inner wall of the container to the impact range of the hammerhead (the central area of ​​the container), reducing the particle size difference of the crushed material.

[0010] Furthermore, the compaction module also includes:

[0011] An eccentric wheel is connected to a third power device, which drives the eccentric wheel to rotate.

[0012] A connecting block, which is fitted onto the outside of the eccentric wheel and rotates relative to the eccentric wheel;

[0013] A connecting rod, one end of which is fixedly connected to the connecting rod, and the other end of which is connected to the hammer head.

[0014] When the third power unit drives the eccentric wheel to rotate, the connecting block fitted on the outside of the eccentric wheel will move back and forth with the eccentric movement of the eccentric wheel, thereby driving the hammer head to make vertical linear movement.

[0015] Furthermore, the tamping module also includes a connecting sleeve rod, which is fitted onto the outside of the connecting rod. The connecting sleeve rod is connected to the second power device, which drives the connecting sleeve rod to rotate around its own circumference. The spiral scraper is fixedly connected to the connecting sleeve rod.

[0016] This invention uses a third power device to drive the connecting rod to make vertical linear motion inside the connecting sleeve rod, and a second power device to drive the connecting sleeve rod to make rotational motion around the connecting rod. Both share the same central axis, which greatly reduces the radial space occupied by the equipment and makes the overall structure more compact.

[0017] Furthermore, the crushing mechanism also includes a lifting mechanism, which drives the crushing module to move vertically.

[0018] Furthermore, the lifting mechanism includes:

[0019] First power unit

[0020] The first power unit is mounted on the fixed frame.

[0021] The slide is equipped with the tamping module, the second power device, and the third power device. The slide is slidably engaged with the fixed frame and is driven to move vertically by the first power device.

[0022] The first power unit drives the carriage to rise, allowing the tamping module to quickly separate from the container, freeing up ample operating space above the container. Operators can more easily perform actions such as adding raw materials and pouring finished products, reducing the risk of material spillage during operation and mitigating safety hazards such as bumps and knocks caused by confined operating space. Furthermore, the absence of obstruction between the tamping module and the container after separation facilitates cleaning of both the tamping module (e.g., hammers, spiral scrapers) and the interior of the container.

[0023] Furthermore, a movable part is fixed at the bottom of the container.

[0024] Operators can move containers simply by pushing them, eliminating the need for strenuous handling. Whether moving empty containers from the storage area to under the crushing module or moving finished containers from the equipment to the next process, the task can be completed relatively easily, reducing the workload for operators.

[0025] Furthermore, a limiting frame is provided on the front side of the fixed frame, and clamping plates are provided on opposite sides inside the limiting frame. The inner side of the clamping plate matches the side wall of the container, and an adjusting screw is rotatably provided on the outer side of the clamping plate. The adjusting screw is threadedly connected to the limiting frame.

[0026] The limiting frame provides circumferential limiting space for the container. When the container is pushed under the tamping module by the moving part, the limiting frame can initially limit the lateral displacement of the container. At the same time, the inner side of the clamping plate matches the side wall of the container. By rotating the adjusting screw, the clamping plate can be driven to move towards the container and abut against the side wall of the container, forming a clamp on the container from opposite sides to fix the container in the preset position, reducing its deviation, shaking or even tipping during the impact of the tamping module or the rotation of the spiral scraper.

[0027] This utility model has the following advantages:

[0028] This invention features a spiral scraper surrounding the outside of the hammerhead, which is driven by a second power device to rotate around its circumference. When the hammerhead moves vertically under the drive of a third power device to impact and crush the material, the rotating spiral scraper can scrape off the raw material adhering to the inner wall of the container. The spiral structure then transports the raw material accumulated near the inner wall of the container to the impact range of the hammerhead (the central area of ​​the container), reducing the particle size difference of the crushed material.

[0039] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0040] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0041] As described in the background section, existing technologies based on a single reciprocating impact motion have the following drawbacks when processing various food ingredients. When the hammer (i.e., the tamping block) impacts downwards, in addition to crushing the ingredient directly below, it also compresses some of the ingredient at the bottom towards the periphery. Because the cylinder of the device has a relatively fixed structure, the compressed ingredient gradually accumulates near the inner wall of the cylinder. The hammer's movement trajectory is limited to a reciprocating motion along the cylinder's axial direction, restricting its effective range to the central area of ​​the cylinder and failing to impact the accumulated ingredient near the inner wall, making it difficult to effectively impact this accumulated ingredient.

[0042] Example 1:

[0043] Therefore, in order to solve the above-mentioned technical problems existing in the prior art, this embodiment provides a raw material crushing mechanism, such as... Figure 1 , 2 As shown, the crushing mechanism may include:

[0044] Container module 400, such as Figure 4 As shown, the container module includes a container 410, which contains a limited amount of raw materials.

[0045] 300 tamping module, such as Figure 3 As shown, the tamping module includes a hammer head 340 and a spiral scraper 330. The spiral scraper is wrapped around the outside of the hammer head and contacts the inner wall of the container.

[0046] The third power device 500 drives the hammer head to move vertically.

[0047] The second power unit 200 drives the spiral scraper to rotate around its own circumference.

[0048] Specifically, the container is configured to correspond to the hammerhead. Before activating the second and third power devices, a preset amount of raw materials are first added to the container. Then, the second and third power devices are activated. The third power device drives the hammerhead to move vertically to impact and crush the materials. The second power device drives the spiral scraper to rotate. The rotating spiral scraper can scrape off the raw materials adhering to the inner wall of the container. The spiral structure transports the raw materials accumulated near the inner wall of the container to the impact range of the hammerhead in the middle area of ​​the container, reducing the particle size difference of the crushed raw materials.

[0049] For example, such as Figure 3 As shown, the compaction module further includes:

[0050] Eccentric wheel 360, which is connected to a third power device, and the third power device drives the eccentric wheel to rotate;

[0051] Connecting block 350, which is fitted on the outside of the eccentric wheel and rotates relative to the eccentric wheel;

[0052] Connecting rod 310, one end of which is fixedly connected to the connecting rod, and the other end of which is connected to the hammer head.

[0053] When the third power unit drives the eccentric wheel to rotate, the connecting block fitted on the outside of the eccentric wheel will move back and forth with the eccentric movement of the eccentric wheel, thereby driving the hammer head to make vertical linear movement.

[0054] For example, such as Figure 3 As shown, the tamping module also includes a connecting sleeve rod 320, which is fitted on the outside of the connecting rod. The connecting sleeve rod is connected to the second power device, which drives the connecting sleeve rod to rotate around its own circumference. The spiral scraper is fixedly connected to the connecting sleeve rod.

[0055] The third power unit drives the connecting rod to make vertical linear motion inside the connecting sleeve rod, while the second power unit drives the connecting sleeve rod to rotate around the connecting rod. Both share the same central axis, which greatly reduces the radial space occupied by the equipment and makes the overall structure more compact.

[0056] In this embodiment, the second and third power devices can be selected as servo motors.

[0057] In this embodiment, the crushing mechanism further includes a lifting mechanism 100, which drives the crushing module to move vertically.

[0058] For example, the lifting mechanism includes:

[0059] First power unit 110

[0060] The first power unit is mounted on the fixed frame 130.

[0061] The slide 120 is on which the tamping module, the second power device, and the third power device are all installed. The slide slide is slidably engaged with the fixed frame and is driven to move vertically by the first power device.

[0062] In this embodiment, the connecting sleeve is rotatably connected to the slide, and the second and third power devices are fixedly mounted on the slide. The second power device can be connected to the connecting sleeve via a synchronous belt transmission structure or a sprocket transmission structure. The first power device can be a servo motor, which is connected to the slide via a sprocket transmission mechanism, a belt transmission mechanism, or other transmission structures capable of achieving linear sliding motion. Alternatively, the first power device can be a cylinder, hydraulic cylinder, or similar device directly connected to the slide, driving the slide to move linearly through the extension and retraction of the piston rod.

[0063] The primary power unit lifts the carriage, allowing the tamping module to quickly separate from the container, freeing up ample operating space above the container. This enables operators to more easily add raw materials and pour finished products, reducing the risk of spillage and minimizing safety hazards such as bumps and knocks caused by limited space. Furthermore, the separation of the tamping module and container allows for easy cleaning of components like the hammers, spiral scrapers, and the interior of the container.

[0064] In this embodiment, a movable part 420 is fixed to the bottom of the container. The movable part may be a frame with rollers.

[0065] Operators can move containers without strenuous handling; simply pushing is sufficient. Whether moving empty containers from the storage area to under the crushing module, or moving crushed finished product containers from the equipment to the next process such as screening or packaging, the task can be completed relatively easily, reducing the labor intensity of operators.

[0066] In addition, a limiting frame 131 is provided on the front side of the fixed frame, and clamping plates 150 are provided on opposite sides inside the limiting frame. The inner side of the clamping plate matches the side wall of the container, and an adjusting screw 140 is rotatably provided on the outer side of the clamping plate. The adjusting screw is threadedly connected to the limiting frame.

[0067] The limiting frame provides circumferential limiting space for the container. When the container is pushed under the tamping module by the moving part, the limiting frame can initially limit the lateral displacement of the container. At the same time, the inner side of the clamping plate matches the side wall of the container. By rotating the adjusting screw, the clamping plate can be driven to move towards the container and abut against the side wall of the container, forming a clamp on the container from opposite sides to fix the container in the preset position, reducing its deviation, shaking or even tipping during the impact of the tamping module or the rotation of the spiral scraper.

[0068] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
