Description

Technical Field

[0001] This utility model relates to the technical field of Roman blind accessories, and in particular to a food crusher. Background Technology

[0002] Food crushers are core equipment in the processing of fruits, vegetables, grains, and meats. Their performance directly affects raw material utilization, product fineness, and the continuous operation capability of the production line. Existing food crushers generally adopt a structure with a circular cutter head and a central bolt clamping it. The cutter head is fixed to the center of the turntable via a central threaded shaft or an annular cover. The feed inlet always partially overlaps with the cutter head, and the material continuously falls into the crushing zone under gravity, where it is sheared by the high-speed rotating blades.

[0003] However, the traditional method of fixing the cutter head with a center bolt requires tools to be inserted into the narrow crushing chamber and the bolt to be rotated multiple times to disassemble and assemble the cutter head. The bolt threads are easily filled with fruit and vegetable fibers, sugar, or bone residue, causing jamming and making it difficult for operators to operate. The complicated assembly and disassembly not only increases the labor intensity of workers, but also leaves unsanitary areas due to incomplete cleaning.

[0004] Furthermore, the existing circular cutter head always overlaps with the feed inlet, and the material falls continuously under the action of gravity. Too many particles can easily accumulate in the crushing chamber in a short period of time. The centrifugal force generated by the high-speed rotation of the cutter head throws the material that has not been fully sheared against the chamber wall, and it is squeezed against the subsequent falling raw material to form a bridge, thereby blocking the subsequent feeding and affecting the crushing efficiency.

[0005] To address the aforementioned shortcomings, a food crusher is provided. Summary of the Invention

[0006] The purpose of this utility model is to provide a food crusher in order to solve the above-mentioned problems.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a food crusher, comprising a machine body, a crushing chamber installed on the machine body, and an inlet / outlet structure disposed on the crushing chamber, and further comprising: The turntable, located in the crushing chamber, rotates through a drive component installed in the machine body. A cutting groove is formed through the interior of the turntable, and the cutting groove extends from the outer edge of the turntable toward its center. The cutter head is installed in the cutter slot through a snap-fit ​​structure, and periodically sweeps across the feed area of ​​the crushing chamber as it rotates.

[0008] Preferably, the inside of the cutter groove is provided with a bracket to accommodate the cutter disc, and when the cutter disc is placed on the bracket, it is flush with the upper surface of the turntable.

[0009] Preferably, the bracket forms a partition structure within the blade groove, dividing the blade groove into: The material discharge zone is for materials crushed by the cutter head to pass through and be discharged downwards; The locking zone provides axial and / or circumferential limiting to the corresponding end of the cutter head, allowing the cutter head to be detachably fixed to the bracket.

[0010] Preferably, a bushing is fixed on the bracket, the bushing is coaxially arranged with the rotation axis of the turntable, and its inner hole is provided with a spline groove for forming an axially sliding anti-torsional connection with the spline section of the output shaft of the drive component.

[0011] Preferably, the sidewall of the bushing has a non-smooth structure, which pulls the turntable to move axially along the output shaft of the drive component.

[0012] Preferably, the non-smooth structure is a wedge-shaped block.

[0013] Preferably, the cutter head has a groove inside, and the inner contour of the groove is larger than the rotational envelope of the bushing and the non-smooth structure, so that the cutter head can be freely fitted into or removed from the bushing along the axial direction.

[0014] Preferably, the snap-fit ​​structure consists of a baffle and a snap-fit ​​groove provided at the opposite end of the cutter head, and a snap-fit ​​block on the side wall of the bracket; after the cutter head is pressed down into place, the snap-fit ​​block elastically snaps into the snap-fit ​​groove, while the baffle is limited by the locking area.

[0015] Preferably, the side edge of the locking area is provided with an arc-shaped clearance notch coupled to the contour of the baffle; after the cutter head is pressed down into place, the baffle is embedded in the arc-shaped clearance notch and fits against the end face of the arc-shaped clearance notch.

[0016] Preferably, a handle is integrally provided on the side edge of the cutter head, and after the cutter head is locked, the outer surface of the handle is coplanar with the circumferential side wall of the turntable.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this application, the cutter head and the bracket adopt a double-end snap-fit ​​structure with axial and circumferential limiting, and the unlocking is completed by an exposed handle. The entire assembly and disassembly process only requires pressing or pulling action, without any auxiliary tools, which can complete the replacement or cleaning of the cutter head, thereby achieving the purpose of convenient cleaning.

[0018] 2. In this application, the elliptical cutter head periodically sweeps across the feed inlet with its long axis, forming an alternation of shearing and blocking. This not only concentrates the crushing of materials in a wide range, but also closes the feed inlet by the turntable at the moment of rotation, breaking the arch bridge effect and preventing continuous material feeding blockage, thereby significantly improving crushing efficiency and smoothness.

[0019] 3. In this application, the locking point is hidden at the narrowest end of the cutter head and extends to the opposite side of the center, so that the snap-fit ​​structure completely avoids the shearing area. The axial clamping and circumferential positioning are completed at the same time as the cutter head is pushed into the bushing. This can not only make full use of the crushing space, but also simplify the number of parts and assembly steps. Attached Figure Description

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1-8 This utility model provides a technical solution: a food crusher, comprising a body 1, a crushing chamber 2 installed on the body 1, and an infeed / discharge structure disposed on the crushing chamber 2, including: Turntable 4 is located in crushing chamber 2 and its rotation is controlled by a drive unit installed in machine body 1.

[0024] The crushing chamber 2 is fixed to the machine body 1, with a feed inlet 201 on its top wall and a discharge outlet 202 on its bottom wall, which together form the feeding and discharging channels. Material is fed into the feed inlet 201 by a conveyor or manually, and after being crushed, is discharged outwards through the discharge outlet 202. The turntable 4 is rotatably suspended inside the crushing chamber 2 via a splined connection to the output shaft of the drive component.

[0025] The machine body 1 serves as the base for the entire machine, and the drive unit is installed inside it. The rotational power of the turntable 4 is provided by the drive unit installed inside the machine body 1. The drive unit can be any type known in the art, including but not limited to a geared motor, a combination of belt and motor, or a direct-drive torque motor. Its output shaft is connected to the bushing 6 via a spline to achieve torque transmission. Since the drive unit itself is common knowledge in the field of food machinery, and its specific structure and control method are irrelevant to the innovation of this utility model, it will not be described in detail here.

[0026] The cutter groove 401 is formed through the interior of the turntable 4. The cutter groove 401 extends from the outer edge of the turntable 4 toward its center and covers the rotation center area of ​​the turntable 4. The cutter disc 8 is installed in the cutter groove 401 by a snap-fit ​​structure. When the cutter disc 8 rotates, it periodically sweeps across the feeding area of ​​the crushing chamber 2.

[0027] The cutter head 8 has an elliptical structure, with its major axis covering the radial length of the cutter groove 401. As the cutter head 8 rotates with the turntable 4, its wide section periodically sweeps across the feeding area of ​​the feed inlet 201, shearing and crushing the material. Once it passes, the turntable 4 blocks the feed inlet 201, facilitating the discharge of the crushed material through the outlet 202. This periodic sweeping across the feeding area of ​​the feed inlet 201 avoids the arching effect caused by continuous material falling, thus improving subsequent crushing efficiency. The narrow section of the cutter head 8 extends to the opposite side of the turntable 4's rotation center, where it engages with a locking structure at its end after passing through the bushing 6, achieving axial and circumferential positioning. By placing the locking parts on the side, which does not occupy the crushing space, this structure ensures stable locking of the cutter head 8 while simplifying the design and arrangement of the locking structure.

[0028] Example 2

[0029] The difference from the technical solution in Embodiment 1 is that, as Figure 3-7 As shown, the inside of the tool groove 401 is provided with a bracket 5 to accommodate the tool disc 8. When the tool disc 8 is placed on the bracket 5, it is flush with the upper surface of the turntable 4.

[0030] The bracket 5 forms a sunken support platform within the cutter groove 401, providing support and a height reference for the cutter head 8. After assembly, the upper surface of the cutter head 8 is flush with the end face of the turntable 4, eliminating step differences. The crushing load is transferred to the turntable 4 via the bracket 5, thereby achieving the goal of reducing the thickness of the cutter head 8 without reducing its strength. At the same time, it avoids material retention and cleaning dead corners, achieving the effects of quick disassembly, no leveling required, and easy cleaning.

[0031] The bracket 5 forms a partition structure within the tool groove 401, dividing the tool groove 401 into: The material discharge zone is for materials crushed by the cutter head 8 to pass through and be discharged downwards; The locking zone provides axial and / or circumferential limiting to the corresponding end of the cutter head 8, allowing the cutter head 8 to be detachably fixed to the bracket 5.

[0032] This technical solution uses a bracket 5 to form a partition structure within the cutter groove 401, dividing the cutter groove 401 into two functional areas. The material discharge area guides the crushed material downwards to ensure smooth discharge. The locking area uses a limiting structure to achieve detachable fixing of the cutter disc 8, balancing crushing efficiency and ease of assembly, thus improving the functional integration and maintenance convenience of the equipment.

[0033] Example 3

[0034] The difference from the technical solution in Embodiment 1 is that, as Figure 3-7 As shown, a bushing 6 is fixed on the bracket 5. The bushing 6 is coaxially arranged with the rotation axis of the turntable 4. Its inner hole is provided with a spline groove, which is used to form an axially sliding anti-torsional connection with the spline section of the output shaft of the drive component.

[0035] The bushing 6 is fixedly connected to the turntable 4. It cooperates with the spline section of the drive shaft through the inner hole spline groove, which not only ensures the torque transmission of the drive components, but also allows the entire turntable 4 to be pulled out along the axial direction as a whole, so as to facilitate disassembly and assembly.

[0036] The sidewall of the bushing 6 has a non-smooth structure, which pulls the turntable 4 to move axially along the output shaft of the drive component. The non-smooth structure is a wedge-shaped block 601.

[0037] The cutter head 8 has a groove 804 inside. The inner contour of the groove 804 is larger than the rotational envelope of the bushing 6 and the non-smooth structure, so that the cutter head 8 can freely fit into or move out of the bushing 6 along the axial direction.

[0038] The uneven structure of the bushing 6's sidewall allows the operator to directly grip the bushing 6 and utilize the protruding part of the wedge block 601 as an anti-slip and force-bearing component, enabling the turntable 4 to move axially along the output shaft of the drive component. This improves operational convenience and safety, while avoiding slippage or difficulty in applying force caused by the smooth surface of the bushing 6. The slot 804 inside the cutter head 8 has an inner contour larger than the rotational envelope of the bushing 6 and the wedge block 601. During the installation or removal of the cutter head 8, the slot 804 provides sufficient clearance for the bushing 6 and the wedge block 601 on its sidewall, ensuring that the cutter head 8 can smoothly fit into or move out of the bushing 6 axially, thereby simplifying the assembly process of the cutter head 8 and improving maintenance efficiency.

[0039] Example 4

[0040] The difference from the technical solution in Embodiment 1 is that, as Figure 3-7 As shown, the snap-fit ​​structure consists of a baffle 803 and a snap-fit ​​groove 802 provided at the opposite end of the cutter head 8, and a snap-fit ​​block 7 on the side wall of the bracket 5; after the cutter head 8 is pressed down into place, the snap-fit ​​block 7 is elastically snapped into the snap-fit ​​groove 802, and at the same time the baffle 803 is limited by the locking area.

[0041] The side edge of the locking area is provided with an arc-shaped clearance notch that is coupled with the contour of the baffle 803; after the cutter head 8 is pressed down into place, the baffle 803 is embedded in the arc-shaped clearance notch and fits against the end face of the arc-shaped clearance notch.

[0042] A handle 801 is integrally provided on the side edge of the cutter head 8. After the cutter head 8 is locked, the outer surface of the handle 801 is coplanar with the circumferential side wall of the turntable 4.

[0043] When the cutter head 8 slides into the cutter groove 401 along the bushing 6, the baffle 803 first enters the arc-shaped clearance notch of the locking area. This notch provides positioning and accommodating space for the baffle 803, allowing the cutter head 8 to be circumferentially aligned first, eliminating tangential misalignment during subsequent snap-fitting.

[0044] As the cutter head 8 continues to press down, the inclined surface at the front end of the cutter head 8 and the inclined surface at the top of the locking block 7 interact with each other, forcing the front end of the turntable 4 to elastically deform outward. When the plane of the retaining groove 802 passes the apex of the locking block 7, the front end of the turntable 4 rebounds, and the locking block 7 is inserted into the retaining groove 802, completing the axial locking. At this time, the bottom of the locking block 7 abuts against the retaining groove 802, while the baffle 803 is blocked by the end face of the arc-shaped clearance notch, forming a bidirectional closure, so that the cutter head 8 is fixed in both the axial and circumferential directions.

[0045] When disassembly is required, use your fingertips or tools to pry the handle 801 so that the front end of the handle 801 elastically deforms outward, allowing the buckle groove 802 to be released from its constraint. Then, by pulling the cutter disc 8, the baffle 803 slides out along the arc-shaped clearance notch, and the cutter disc 8 can be lifted upward to complete the quick disassembly.

[0046] Example 5

[0047] The difference from the technical solution in Embodiment 1 is that, as Figure 8 As shown, inside the crushing chamber 2, a material-pushing component 3 is installed between the cutter head 8 and the discharge port 202, which can rotate synchronously with the turntable 4. The material-pushing component 3 is integrally formed by a central sleeve shaft and a radially extending actuating arm. The sleeve shaft and the output shaft of the drive component are connected by a spline, so it can rotate synchronously with the crushing operation without additional power.

[0048] As the material cut to the target particle size by the cutter head 8 passes through the discharge area and falls below the turntable 4, the agitator arm continuously sweeps across the bottom wall of the crushing chamber 2, pushing the accumulated material to the discharge port 202. The agitator arm is made of food-grade flexible TPU, which can maintain a slight elastic contact with the bottom wall of the crushing chamber 2, avoiding metal residue and abnormal noise caused by rigid scraping, thus ensuring a smooth discharge process and no residue in the chamber, ensuring food safety while allowing the equipment to operate quietly.

[0049] The above description of the 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.
