Description

Technical Field

[0001] This utility model belongs to the field of food testing technology, specifically relating to a food crushing and sampling machine for food testing. Background Technology

[0002] Food testing involves detecting harmful substances in food according to national standards, primarily for harmful and toxic indicators such as heavy metals and aflatoxin. Food sampling is a crucial step in the testing process. This requires pulverizing the food sample to extract specific components, which necessitates the use of a food pulverizer / sampler.

[0003] Modern food crushing and sampling machines typically use a pair of crushing rollers with a fixed spacing to crush and grind food. However, the fixed roller spacing cannot match the diversity of food materials. For example, when processing high-hardness fibrous materials (such as nuts and shelled grains), if the spacing is too small, the material will easily get stuck and the rollers will wear out. If the spacing is too large, the material can only be rubbed but not crushed. When processing medium- to low-hardness sticky materials (such as biscuits and sauce clumps), if the spacing is too small, the material will be over-crushed into fine powder (such as biscuit powder flying away). If the spacing is too large, the material will get stuck in the roller gap or be flattened, losing the purpose of crushing. Utility Model Content

[0004] (1) Technical problems to be solved To address the shortcomings of existing technologies, the purpose of this utility model is to provide a food crushing and sampling machine for food testing. This addresses the problem that existing technologies typically use a pair of crushing rollers with a fixed spacing to crush and grind food. However, the fixed roller spacing cannot match the diversity of food materials. For example, when processing high-hardness fibrous materials (such as nuts and shelled grains), too small a spacing can easily cause material jamming and roller wear, while too large a spacing can only rub the material without crushing it. Similarly, when processing medium- to low-hardness sticky materials (such as biscuits and clumps of sauce), too small a spacing can easily lead to over-crushing into fine powder (such as biscuit powder flying away), while too large a spacing can cause the material to get stuck in the roller gap or simply be flattened, thus losing the purpose of crushing.

[0005] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides a food crushing and sampling machine for food testing, including a machine body, a feeding part fixed at the top of the machine body, a discharging part installed at the bottom center of the machine body, a support frame fixed at the bottom of the machine body, and a control area at the front end of the machine body. An adaptive crushing mechanism is provided inside the machine body, and a sampling mechanism is provided on the surface of the support frame base. The adaptive crushing mechanism includes a driving crushing component, which is located on one side of the inside of the machine body, and an adaptive adjustment component is installed on the other side of the inside of the machine body.

[0006] Furthermore, the driving crushing component includes a first servo motor, which is mounted on the outside of the machine body, and the output end of the first servo motor is connected to an active crushing roller.

[0007] Furthermore, the adapter adjustment component includes mounting brackets, which are respectively located on both sides of the interior of the machine body. One end of one of the mounting brackets is equipped with a second servo motor, and the output end of the second servo motor is connected to a transmission screw. A screw sleeve is screwed around one side of the transmission screw, and a guide frame is fixed around the screw sleeve. Screw protective covers are installed on both sides of the guide frame. A fixed crushing roller is fixedly connected to the inner end face of the guide frame, and a sliding frame is fixedly connected to the other end of the fixed crushing roller. Horizontal guide blocks are provided above the two mounting brackets.

[0008] Furthermore, the two ends of the lead screw protective cover are respectively connected to the corresponding middle ends of the guide frame and one of the mounting frames, and the lead screw protective cover covers the periphery of the transmission lead screw.

[0009] Furthermore, the fixed crushing roller is connected to a horizontal guide by means of a guide frame, a sliding frame, a horizontal guide block, and two opposing mounting frames.

[0010] Furthermore, the sampling mechanism includes anti-deviation rails, which are respectively disposed on both sides of the bottom surface of the support frame. A guide rail seat is mounted above the two anti-deviation rails, and a sampling collection box is fixed above the guide rail seat.

[0011] Furthermore, the sampling collection box utilizes a guide rail seat and an anti-deviation rail to form a limiting sliding connection.

[0012] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This invention allows operators to pre-adjust the distance between the active crushing roller and the fixed crushing roller inside the machine according to the different detection dimensions required for the types of food to be processed. The adjustment method is as follows: the operator starts the second servo motor to rotate the transmission screw. At this time, the screw sleeve interacting with the screw can carry the guide frame and the fixed crushing roller at its inner end, and with the guidance of the sliding frame and the horizontal guide block, move horizontally along the mounting frame, thereby achieving the purpose of adjusting the distance between the fixed crushing roller and the active crushing roller. After the adjustment is completed, the operator starts the first servo motor to rotate the active crushing roller. At this time, the active crushing roller and the fixed crushing roller can crush and grind the food fed by the operator through the feeding part. It is worth mentioning that in this solution, the transmission screw inside the mounting frame is equipped with a screw protective cover, and the opening surface of the mounting frame faces downward, which can effectively prevent food residues from splashing onto the screw and causing damage.

[0013] After the food is crushed and ground, it will flow into the sampling collection box placed below. Staff can then take samples from the sampling collection box. It should be noted that the guide rail and anti-deviation rail below the sampling collection box can effectively prevent the box from shifting and avoid material spillage due to the box shifting.

The adapter adjustment component 62 includes a mounting bracket 621, which is located on both sides of the interior of the machine body 1. A second servo motor 622 is mounted on one end of one of the mounting brackets 621, and the output end of the second servo motor 622 is connected to a transmission screw 623. A screw sleeve 624 is screwed around one side of the transmission screw 623, and a guide bracket 625 is fixed around the screw sleeve 624. Screw protective covers 626 are mounted on both sides of the guide bracket 625. The two ends of the screw protective covers 626 are respectively connected to the corresponding middle ends of the guide bracket 625 and one of the mounting brackets 621, and the screw protective covers 626 cover the periphery of the transmission screw 623. The inner end face of the guide bracket 625 is fixed. A fixed crushing roller 627 is connected, and a sliding frame 628 is fixedly connected to the other end of the fixed crushing roller 627. A horizontal guide block 629 is set above the two mounting frames 621. The fixed crushing roller 627 forms a horizontal guide connection with the guide frame 625, the sliding frame 628, the horizontal guide block 629, and the two opposing mounting frames 621. The operator can adjust the distance between the active crushing roller 612 and the fixed crushing roller 627 in the machine body 1 in advance according to the different detection dimensions required for the type of food to be processed. The adjustment method is as follows: the operator starts the second servo motor 622 to rotate the transmission screw 623. At this time, the screw sleeve 624, which interacts with the screw, can carry the guide frame 625 and the fixed frame 629 set at its inner end. The fixed crushing roller 627, in conjunction with the sliding frame 628 and the horizontal guide block 629, moves horizontally along the mounting frame 621 to adjust the distance between the fixed crushing roller 627 and the active crushing roller 612. After adjustment, the operator starts the first servo motor 611 to rotate the active crushing roller 612. At this time, the active crushing roller 612, in conjunction with the fixed crushing roller 627, can crush and grind the food fed by the operator through the feeding section 2.
