Description

Technical Field

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

[0002] Food inspection includes sensory testing of food, detection of nutrients, additives, and harmful substances in food. Food testing requires sample processing, and sample crushing is an important step in sample pretreatment. It is usually used to prepare samples for subsequent analysis or testing, thus requiring a sample crushing device for food testing.

[0003] However, most existing food testing sample crushing devices use a motor to drive a cutting blade for rapid cutting, thereby crushing the food. However, the cutting blade generates a lot of heat after rotating rapidly for a certain period of time, which can lead to sample overheating or cross-contamination, resulting in high temperature and chemical changes.

[0004] To address these issues, those skilled in the art have proposed a sample crushing device for food testing. Utility Model Content

[0005] The purpose of this invention is to provide a sample crushing device for food testing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A sample crushing device for food testing, comprising:

[0008] A base plate, on which an inverted U-shaped frame is fixedly installed;

[0009] A rotating mechanism is installed at the center of the base plate surface, and a fixing plate is installed at the top of the rotating mechanism;

[0010] The pressing mechanism is installed at the center of the inner wall of the top of the U-shaped frame, and the bottom end of the pressing mechanism is directly opposite the fixed plate;

[0011] The two fixing mechanisms are respectively installed on the inner walls of the two sides of the U-shaped frame near the middle. One end of each fixing mechanism is equipped with the same sleeve, which is fitted onto the outer circumferential wall of the fixing plate.

[0012] Preferably, support arms are fixedly installed on both sides of the top outer wall of the base plate near the rotating mechanism, and the surface of the support arms is attached to the surface of the fixed plate.

[0013] Preferably, the rotating mechanism includes a motor, which is mounted at the center of the base plate surface. A transmission shaft is fixedly connected to the top end of the motor output shaft, and a shaft fixing seat is sleeved on one end of the transmission shaft.

[0014] Preferably, a connecting plate is fixedly installed at the top of the shaft fixing seat, and the top of the connecting plate is installed at the center of the bottom outer wall of the fixing plate.

[0015] Preferably, the fixing mechanism includes a mounting frame, which is installed on one side of the U-shaped frame. An electric slide rail is vertically installed on the inner wall of the mounting frame. A slider is slidably engaged on one outer wall of the electric slide rail. A connecting rod is fixedly installed on one outer wall of the slider. Two connecting rods are respectively installed on the outer walls of the two sides of the sleeve.

[0016] Preferably, the pressing mechanism includes an electric cylinder, which is installed at the center of the inner wall of the top of the U-shaped frame. A heavy pressure block is fixedly installed at the bottom end of the extension rod of the electric cylinder. The cross-section of the heavy pressure block is the same as the cross-section of the fixed plate. A circular opening is opened on one side of the bottom outer wall of the heavy pressure block. Multiple telescopic components are provided on the top inner wall of the circular opening. The same secondary pressure block is installed at the bottom end of the telescopic components. The secondary pressure block is slidably engaged with the inner circumference of the circular opening. Multiple semi-circular grinding balls are fixedly installed on the bottom outer wall of the secondary pressure block.

[0017] Preferably, the telescopic component includes a fixed cylinder, which is installed on the top inner wall of the circular opening. A telescopic rod is vertically inserted into the bottom outer wall of the fixed cylinder. A spring is wound around the circumferential outer wall of the fixed cylinder and the telescopic rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (1) This utility model is equipped with a pressing mechanism and a rotating mechanism. When crushing food samples, the sample is poured onto the surface of the fixed plate, and then the food sample is crushed by pressing the fixed plate with a heavy block. Then the motor is started to drive the fixed plate to rotate slowly, and the electric cylinder performs slow, small-amplitude reciprocating motion. Then the crushed food sample is crushed again by the secondary pressing block and the semi-circular grinding balls on its surface. The heat generated in the whole process is low and will not affect the food sample, thereby avoiding the impact on the subsequent food sample testing.

[0020] (2) This utility model is equipped with an electric slide rail and a sleeve. The sleeve is fitted on the outside of the fixed plate and forms a cavity with the fixed plate and the heavy block, which facilitates the crushing of food samples. After crushing, the sleeve is moved upward by the slider of the electric slide rail, which facilitates the removal of the internal food samples for subsequent testing. Attached Figure Description

[0029] 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.

[0030] Please see Figure 1-Figure 4 As shown, a sample crushing device for food testing includes:

[0031] A base plate 1, with an inverted U-shaped frame 4 fixedly installed on the top outer wall of the base plate 1;

[0032] Rotating mechanism 2 is installed at the center of the surface of base plate 1, and a fixing plate 8 is installed at the top of rotating mechanism 2;

[0033] Pressing mechanism 6 is installed at the center of the top inner wall of U-shaped frame 4, with the bottom end of pressing mechanism 6 facing the fixing plate 8.

[0034] Fixing mechanism 5, two fixing mechanisms 5 are respectively installed on the inner walls of the two sides of the U-shaped frame 4 near the middle position. One end of the two fixing mechanisms 5 is equipped with the same sleeve 7, and the sleeve 7 is fitted onto the outer circumferential wall of the fixing plate 8.

[0035] As can be seen from the above, the food sample is placed on the surface of the fixed plate 8, and then the pressing mechanism 6 is activated. The pressing mechanism 6 presses down to crush the food sample. Then the rotating mechanism 2 is activated to drive the fixed plate 8 to move slowly, thereby cooperating with the reciprocating motion of the pressing mechanism 6 to crush the food sample again. Then the sleeve 7 is lifted by the fixed mechanism 5, and the crushed food sample can be taken out from the surface of the fixed plate 8 for subsequent testing.

[0036] Specifically, support arms 3 are fixedly installed on both sides of the top outer wall of the base plate 1 near the rotating mechanism 2, and the surface of the support arms 3 is attached to the surface of the fixed plate 8.

[0037] As can be seen from the above, the top of the support arm 3 is located at the bottom of the fixed plate 8, which plays an auxiliary support role.

[0038] Specifically, the rotating mechanism 2 includes a motor 201, which is installed at the center of the surface of the base plate 1. A transmission shaft is fixedly connected to the top of the output shaft of the motor 201, and a shaft fixing seat 202 is sleeved on one end of the transmission shaft.

[0039] As can be seen from the above, after starting the motor 201, it drives the transmission shaft to rotate, which in turn drives the shaft fixing seat 202 to rotate, making it easier to drive the fixing plate 8 to rotate slowly and uniformly in the future.

[0040] Specifically, a connecting plate 203 is fixedly installed on the top of the shaft fixing seat 202, and the top of the connecting plate 203 is installed at the center of the bottom outer wall of the fixing plate 8.

[0041] As can be seen from the above, after the motor 201 starts, it drives the connecting plate 203 and the fixed plate 8 to rotate through the transmission shaft and the shaft fixing seat 202, so that the food sample crushing work can continue.

[0042] Specifically, the fixing mechanism 5 includes a mounting bracket 503, which is installed on one side of the U-shaped frame 4. An electric slide rail 501 is vertically installed on the inner wall of the mounting bracket 503. A slider 502 is slidably engaged on one side of the outer wall of the electric slide rail 501. A connecting rod 504 is fixedly installed on one side of the outer wall of the slider 502. The two connecting rods 504 are respectively installed on the outer walls of the two sides of the sleeve 7.

[0043] As can be seen from the above, starting the electric slide rail 501 can drive the slider 502 to move longitudinally, which in turn drives the sleeve 7 to move longitudinally through the connecting rod 504.

[0044] Specifically, the pressing mechanism 6 includes an electric cylinder 601, which is installed at the center of the inner top wall of the U-shaped frame 4. A heavy pressure block 602 is fixedly installed at the bottom end of the extension rod of the electric cylinder 601. The cross-section of the heavy pressure block 602 is the same as that of the fixed plate 8. A circular opening 608 is opened on one side of the bottom outer wall of the heavy pressure block 602. Multiple telescopic parts are provided on the top inner wall of the circular opening 608. The same secondary pressure block 603 is installed at the bottom end of the telescopic parts. The secondary pressure block 603 is slidably engaged with the inner circumference of the circular opening 608. Multiple semi-circular grinding balls 604 are fixedly installed on the bottom outer wall of the secondary pressure block 603.

[0045] As can be seen from the above, the small-amplitude reciprocating motion of the electric cylinder 601 drives the reciprocating motion of the heavy pressure block 602, and the food sample is ground by the heavy pressure block 602, the secondary pressure block 603 and the semi-circular grinding ball 604.

[0046] Specifically, the telescopic component includes a fixed cylinder 606, which is installed on the top inner wall of the circular opening 608. A telescopic rod 605 is vertically inserted into the bottom outer wall of the fixed cylinder 606. A spring 607 is wound around the circumferential outer walls of the fixed cylinder 606 and the telescopic rod 605. The bottom end of the telescopic rod 605 is installed on the surface of the secondary pressure block 603.

[0047] As can be seen from the above, the small-amplitude reciprocating motion of the electric cylinder 601 causes the spring 607 to be continuously compressed and stretched, which causes the telescopic rod 605 to move continuously inside the fixed cylinder 606, thereby driving the reciprocating motion of the secondary pressure block 603. Then, in conjunction with the semi-circular grinding balls 604 on its surface, the food sample is ground, making the food sample more thoroughly crushed.

[0048] Working principle: The food sample is placed on the surface of the fixed plate 8, and then the pressing mechanism 6 is activated. The heavy block 602 presses against the fixed plate 8, which crushes the food sample. The small-amplitude reciprocating motion of the electric cylinder 601 causes the spring 607 to be continuously compressed and stretched, which causes the telescopic rod 605 to move continuously inside the fixed cylinder 606, thereby driving the reciprocating motion of the secondary pressing block 603. Then, in conjunction with the semi-circular grinding balls 604 on its surface, the food sample is ground, making the food sample more thoroughly crushed. At the same time, the motor 201 is activated, which drives the rotation of the transmission shaft, which in turn drives the rotation of the shaft fixing seat 202, causing the fixed plate 8 to rotate slowly and uniformly. In conjunction with the pressing mechanism 6, the food sample is crushed. After the food sample is crushed, the electric slide rail 501 is activated, which drives the slider 502 to move longitudinally. Then, the connecting rod 504 drives the sleeve 7 to move longitudinally. The crushed food sample can then be removed from the surface of the fixed plate 8 for subsequent testing.
