[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 10 The present invention provides a technical solution:

[0035] Example 1:

[0036] An apparatus for determining gel strength, comprising a detection base 1, a scale rod 13, a material rack assembly, and a detection component.

[0037] The upper end of the detection base 1 is provided with a limit frame 2, and the middle of the upper surface of the detection base 1 is provided with a downwardly extending feed port 3. The front end of the detection base 1 is provided with a lower slot 4, which is connected to the feed port 3. The material rack assembly is composed of a pair of parallel upper plates 10 and lower plates 8. Multiple sets of linearly distributed material grooves 5 corresponding to the feed port 3 are provided on the lower plates 8.

[0038] By setting up a lower insert plate 8 with multiple material troughs 5, the lower insert plate 8 can be inserted and pushed in the lower slot 4 to achieve the purpose of switching and realize the continuous detection of multiple colloids.

[0039] The upper insert plate 10 is inserted into the lower end face of the limit frame 2, and the upper insert plate 10 is provided with through holes 29 corresponding to the material trough 5.

[0040] By setting the through hole 29 and the upper insert plate 10 together, the lower end face of the pressure block 12 can be scraped and cleaned after the pressure block 12 is reset.

[0041] The scale rod 13 is vertically installed on the upper left side of the detection base 1. The upper end of the scale rod 13 is horizontally installed with an upper crossbeam 19. The outer wall of the scale rod 13 is vertically set with scales. The upper crossbeam 19 is vertically installed with a telescopic rod 18. The lower end of the telescopic rod 18 is set with a connecting frame 20. The connecting frame 20 is a double-layer plate structure that is horizontally parallel to each other. The positioning sleeve rod 22 is vertically installed between the double-layer plates. The detection component includes a lower crossbeam 16 and a lifting frame 25. One end of the lower crossbeam 16 is slidably sleeved on the scale rod 13. The lower end of the lower crossbeam 16 vertically passes through the limiting frame 2 and the upper insert plate 10. The lower end of the lower crossbeam 16 is set with a pressing block 12 that presses against the material trough 5. The upper end of the lower crossbeam 16 is set with a lifting frame 25. One end of the lifting frame 25 is slidably sleeved on the positioning sleeve rod 22. The other side of the lifting frame 25 is set with a counterweight ring 24.

[0042] By setting up a double-layer plate connecting frame, the lower crossbeam 16 is lowered using the telescopic rod 18, allowing the lower crossbeam 16 to fall freely and press against the colloid. By adding a counterweight ring 24, the gravity of the lower crossbeam 16 is increased, driving the pressure block 12 to squeeze the colloid downwards. By observing the height of the drop on the scale rod 13, the hardness of the colloid can be detected.

[0043] Example 2:

[0044] Based on embodiment 1, the lower insert plate 8 is slidably inserted into the lower slot 4, and a rack 33 is provided at the lower end of the lower insert plate 8. A drive assembly is provided in the inner cavity of the detection base 1. The drive assembly includes a drive gear 6, a drive motor 7 and a rotating shaft 9. The drive motor 7 is connected to the rotating shaft 9, the drive gear 6 is fixedly sleeved on the rotating shaft 9, and the upper end of the drive gear 6 is meshed with the rack 33.

[0045] By setting the drive gear 6 and rack 33 to cooperate, the meshing drive is achieved, thereby realizing the automatic push-up switching of the lower insert plate 8.

[0046] Example 3:

[0047] Based on embodiment 2, the lower end of the limiting frame 2 is provided with a pair of symmetrical upper slots 30 that extend from front to back, and the upper insert plate 10 is provided with a pair of guide strips 32. The ends of the guide strips 32 are chamfered, and the guide strips 32 are slidably inserted into the upper slots 30.

[0048] The guide strip 32 cooperates with the upper slot 30 to limit the position of the upper insert plate 10 and maintain the smooth sliding of the upper insert plate 10.

[0049] A column 11 is vertically installed at the lower end of the lower crossbeam 16. A pressure block 12 is installed at the lower end of the column 11. The outer diameter of the column 11 is smaller than the outer diameter of the pressure block 12. The pressure block 12 is pressed onto the gel in the material trough 5. A lifting hole 35 is provided on the limiting frame 2. The lifting hole 35 corresponds to the through hole 29. The column 11 extends along the lifting hole 35 and the through hole 29 to the lower end of the limiting frame 2. A chamfer 31 is provided at the upper end of the through hole 29.

[0050] By setting the lifting hole 35 and the through hole 29, the column 11 and the pressure block 12 are connected through insertion. After a single test is completed, the column 11 and the pressure block 12 are driven to rise by the telescopic rod 18. At this time, the pressure block 12 is located at the upper end of the upper insertion plate 10. The lower end face of the pressure block 12 is scraped by setting the chamfer 31. At the same time, the chamfer 31 is used to keep the pressure block 12 accurately guided and inserted into the through hole 29.

[0051] Example 4:

[0052] Based on embodiment 3, an extension arm 26 is provided on one side of the lifting frame 25. A vertical through hole 28 is provided on the extension arm 26. The through hole 28 is slidably inserted into the positioning sleeve 22. A spring 21 is vertically sleeved at the lower end of the positioning sleeve 22. The spring 21 is pressed between the extension arm 26 and the lower end plate of the connecting frame 20.

[0053] By setting the positioning sleeve 22 and the extension arm 26 to cooperate, the lower crossbeam 16 can be freely pressed down. After pressing down, it can be further lowered by the compression of the counterweight ring 24.

[0054] The upper outer side of the lifting frame 25 is provided with a circular groove 27, and the counterweight ring 24 is vertically engaged in the groove 27.

[0055] The counterweight ring 24 is positioned and installed by setting the slot 27.

[0056] A collar 15 is provided at one end of the lower crossbeam 16. The collar 15 is slidably sleeved on the scale rod 13. A threaded fastening bolt 17 is provided on the outer arc wall of one side of the collar 15.

[0057] The lower crossbeam 16 is connected to the scale rod 13 by setting a collar 15, and the position of the collar 15 is fixed by using fastening bolts 17.

[0058] Example 5:

[0059] Based on embodiment 4, a limiting groove 14 is vertically provided on one side wall of the scale rod 13, and a side strip 34 is provided on the inner side of the collar 15 that is slidably inserted into the limiting groove 14. The connecting frame 20 is configured as two sets symmetrically arranged on the left and right, and the upper ends of the two sets of connecting frames 20 are fixedly connected to the lower end of the telescopic rod 18 through flange 23.

[0060] By setting the limiting groove 14 and the side strip 34 to cooperate, the positioning and lifting of the collar 15 can be realized, thereby limiting the position of the lower crossbeam 16 and preventing the lower crossbeam 16 from shifting position.

[0061] Example 6:

[0062] Based on embodiment 5, the side wall of the lower crossbeam 16 is provided with positioning holes 36 corresponding to multiple linearly distributed material troughs 5. The side wall of the detection base 1 is provided with an extension support plate 38 extending outward in parallel at the position corresponding to the lower slot 4. The front and rear side walls of the extension support plate 38 are provided with a pair of elongated oval adjustment grooves 37. The middle of the elongated oval adjustment groove 37 is provided with a positioning groove 39 with an inner diameter greater than the width of the elongated oval adjustment groove 37. The distance between the centers of the positioning grooves 39 in adjacent elongated oval adjustment grooves 37 is equal to the distance between adjacent material troughs 5. The elongated oval adjustment grooves 37 correspond to the positioning holes 36. Pins 41 are inserted into the elongated oval adjustment grooves 37 and the positioning holes 36. A positioning screw sleeve 40 is rotatably installed on the pin 41. The positioning screw sleeve 40 is inserted into the positioning groove 39.

[0063] The material rack assembly is stably supported by the extended support plate 38, ensuring smooth advancement of the material rack assembly. The long oval adjustment groove 37 and the pin 41 are designed to work together. After adjustment by motor drive, the pin 41 is inserted into the long oval adjustment groove 37 and the positioning hole 36, so that the material rack assembly can be finely adjusted by using the pin 41. The pin 41 slides laterally into the positioning groove 39 and is screwed into the positioning groove 39 through the thread of the positioning screw sleeve 40, so as to achieve precise alignment and ensure that the material groove 5 is accurately aligned with the pressure block 12 when advancing and switching.
