Description

Technical Field

[0001] This utility model relates to the field of sample testing technology, and in particular to a pulverizing device for food testing. Background Technology

[0002] Food testing involves inspecting the quality of food raw materials, auxiliary materials, semi-finished products, and finished products to determine whether the nutritional components, additives, and harmful substances are within specified ranges. Specific testing steps include sampling, crushing, preparation, and physicochemical analysis. Crushing involves pulverizing the collected sample to facilitate the complete dissolution of its components in reagents. Chinese utility model patent CN222336883U discloses a crushing device for food testing. A descending pressure plate pushes the food sample onto the surface of a blade mesh plate. The blades in the mesh plate and the pressure applied by the pressure plate perform preliminary cutting of the food sample, resulting in a size suitable for further crushing by the blades. However, in this solution, the food sample is easily clogged in the mesh of the blade mesh plate during the preliminary cutting process, leading to sample waste and difficulty in cleaning. Utility Model Content

[0003] The technical problem this invention aims to solve is that in existing food testing crushing devices, food samples are easily clogged in the mesh of the blade screen during the initial cutting process, resulting in sample waste and difficulty in cleaning.

[0004] To solve the above problems, this utility model provides a food testing crushing device. The two ends of the cylinder are respectively provided with a bottom shell and a cover. The bottom shell is provided with a crushing blade that extends into the cylinder. The cylinder is provided with a blade mesh plate. The cover is provided with a pressure plate assembly that can slide along the inner wall of the cylinder. The pressure plate assembly includes a sliding mesh plate and an insert plate. The sliding mesh plate and the blade mesh plate are each formed with a one-to-one corresponding mesh hole. The insert plate is provided with an insert block that can slide and cooperate with the mesh hole.

[0005] The food testing pulverizer provided by this utility model also has the following technical features:

[0006] The pressure plate assembly also includes a pressure cover disposed on the upper side of the sliding mesh plate, and the insertion plate is slidably disposed in the cavity formed by the sliding mesh plate and the pressure cover, so that the insertion block can extend or retract relative to the sliding mesh plate.

[0007] The cover has a threaded hole, and a sleeve is rotatably mounted on the pressure cap. The sleeve has an external thread corresponding to the threaded hole. A screw is rotatably mounted on the insert plate, and an internal thread corresponding to the screw is mounted on the sleeve.

[0008] Both the sleeve and the screw have knobs at their ends.

[0009] The inner wall of the cylinder is provided with vertical grooves, and multiple vertical grooves are spaced apart along the circumference of the cylinder. A sliding rod corresponding to the vertical groove is formed on the cover.

[0010] A motor is provided on the outer side of the bottom shell, and a through hole is provided on the bottom shell. The output end of the motor is rotatably inserted into the through hole and connected to a rotating shaft. The crushing blade is set on the rotating shaft.

[0011] This invention has the following advantages: the control plate assembly moves along the inner wall of the cylinder towards the blade screen to preliminarily cut the food sample on the blade screen until the sliding screen contacts the blade screen. Since the mesh holes of the two correspond one-to-one, the control plate slides along the corresponding mesh holes to push the food sample blocked in the mesh holes to the crushing blade for crushing, avoiding sample waste and reducing cleaning difficulty.

[0015] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0016] like Figures 1 to 3 As shown, the food testing pulverizing device of this utility model has a bottom shell 11 and a cover 12 at both ends of the cylinder 10. The bottom shell 11 is provided with a pulverizing blade 13 that extends into the cylinder 10. The cylinder 10 is provided with a blade mesh plate 14. The cover 12 is provided with a pressure plate assembly that can slide along the inner wall of the cylinder 10. The pressure plate assembly includes a sliding mesh plate 21 and an insert plate 22. The sliding mesh plate 21 and the blade mesh plate 14 are each formed with a corresponding mesh hole 23. The insert plate 22 is provided with an insert block 24 that can slide and cooperate with the mesh hole 23.

[0017] The control plate assembly moves along the inner wall of the cylinder 10 toward the blade screen 14 to perform preliminary cutting on the food sample on the blade screen 14 until the sliding screen 21 contacts the blade screen 14. Since the mesh holes 23 of the two correspond one-to-one, the control plate 22 slides along the mesh holes 23 to push the food sample blocked in the mesh holes 23 to the crusher 13 for crushing, avoiding sample waste and reducing cleaning difficulty.

[0018] The bottom shell 11, the cover 12 and the cylinder 10 can be detachably connected by means of threaded connection or snap-fit ​​connection. The outer surfaces of the bottom shell 11 and the cover 12 can be provided with anti-slip texture for manual installation and disassembly.

[0019] The blade screen 14 has blades on the side closest to the pressure plate assembly. When pressed from top to bottom by the pressure plate assembly, the food sample can be cut by the blades and enter the mesh 23 of the blade screen 14. The mesh 23 of the sliding screen 21 corresponds one-to-one with the mesh 23 of the blade screen 14. That is, the shape, size, and number of the mesh 23, as well as the relative distance and position of adjacent mesh 23, correspond one-to-one. The only difference between the sliding screen 21 and the blade screen 14 is that the blade screen 14 has blades. The size and number of mesh 23 can be selected according to the size of the food sample to be cut. The smaller the size of the mesh 23 and the more mesh 23 there are, the smaller the size of the food sample after initial cutting, and the less wear and noise on the pulverizer 13.

[0020] Preferably, the pressure plate assembly further includes a pressure cover 25 disposed on the upper side of the sliding mesh plate 21, and the insertion plate 22 is slidably disposed in the cavity formed by the sliding mesh plate 21 and the pressure cover 25, so that the insertion block 24 can extend or retract relative to the sliding mesh plate 21.

[0021] When the insert plate 22 is located at the uppermost end of the cavity, the insert block 24 retracts relative to the sliding mesh plate 21, and at this time the lower surface of the insert block 24 is flush with the lower surface of the sliding mesh plate 21; correspondingly, when the insert plate 22 is located at the lowermost end of the cavity, the insert block 24 extends relative to the sliding mesh plate 21 and straightens into the mesh hole 23 of the blade mesh plate 14 to clear the blockage, and at this time the lower surface of the insert block 24 is flush with the lower surface of the blade mesh plate 14.

[0022] Preferably, the cover 12 has a threaded hole, the pressure cap 25 has a rotatable sleeve 26, and the sleeve 26 has an external thread corresponding to the threaded hole; the insert plate 22 has a rotatable screw 27, and the sleeve 26 has an internal thread corresponding to the screw 27.

[0023] Rotate the sleeve 26 to make the pressure plate assembly slide along the inner wall of the cylinder 10, and rotate the screw 27 to make the insert plate 22 slide along the pressure plate assembly, that is, the insert block 24 extends or retracts relative to the sliding mesh plate 21.

[0024] The lower end of the sleeve 26 is rotatably connected to the pressure cap 25 via a bearing. When the sleeve 26 is rotated, the pressure cap 25 can be pushed up and down without rotating. Correspondingly, the lower end of the screw 27 is rotatably connected to the insert plate 22 via a bearing. When the screw 27 is rotated, the insert plate 22 can be pushed up and down without rotating.

[0025] The cover 12 has a threaded hole, and the pressure cover 25 has a rotatable sleeve 26. The sleeve 26 has an external thread corresponding to the threaded hole. As a structural variation, the end of the sleeve 26 is provided with a telescopic rod. The output end of the telescopic rod is inserted into the sleeve 26 and connected to the insert plate 22. The telescopic rod can drive the insert plate 22 to slide along the pressure plate assembly, thereby causing the insert block 24 to extend or retract relative to the sliding mesh plate 21.

[0026] Preferably, both the sleeve 26 and the screw 27 are provided with knobs 28 at their ends.

[0027] Preferably, the inner wall of the cylinder 10 is provided with vertical grooves 29, and multiple vertical grooves 29 are spaced apart along the circumference of the cylinder 10. The pressure cover 25 is provided with a sliding rod 30 corresponding to the vertical grooves 29, so that the pressure plate assembly can only slide along the inner wall of the cylinder 10.

[0028] The upper end of the vertical groove 29 is connected to the opening at the upper end of the cylinder 10, and the lower end of the vertical groove 29 is flush with the upper surface of the blade screen plate 14, so that the sliding screen plate 21 can contact the blade screen plate 14.

[0029] Preferably, a motor is provided on the outer side of the bottom shell 11, and a through hole is provided on the bottom shell 11. The output end of the motor is rotatably inserted into the through hole and connected to a rotating shaft 15. The crushing blade 13 is disposed on the rotating shaft 15.

[0030] It is equipped with corresponding power supply, controller and connecting wires and other components. Multiple crushing blades 13 are arranged at intervals along the circumference of the rotating shaft 15 and at multiple layers at intervals along the axial direction of the rotating shaft 15. The crushing blades 13 in adjacent layers are staggered to improve the crushing effect.

[0031] The working principle of this utility model is as follows:

[0032] Place the food sample on the blade mesh plate 14 and connect the cover 12 to the cylinder 10. Rotate the knob 28 and the sleeve 26 to move the pressure plate assembly along the inner wall of the cylinder 10 toward the blade mesh plate 14 to initially cut the food sample on the blade mesh plate 14 until the sliding mesh plate 21 contacts the blade mesh plate 14, with the mesh holes 23 of the two corresponding one-to-one. At this time, rotate the knob 28 and the screw 27 to make the insert plate 22 slide downward along the pressure plate assembly, that is, the insert block 24 extends relative to the sliding mesh plate 21 to push the food sample blocked in the mesh holes 23 of the blade mesh plate 14 downward and crush it by the crushing blade 13 to avoid sample waste and reduce cleaning difficulty. Remove the bottom shell 11 from the cylinder 10 to collect the crushed food sample.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
