Technical Field

[0001] The utility model relates to the technical field of filling value measuring instruments, and specifically, to a leveling mechanism for the pressure head of a filling value measuring instrument. Background Art

[0002] A tobacco filling measuring instrument is a special detection instrument for measuring the filling capacity of tobacco cuttings, expanded tobacco cuttings, sheeted tobacco, stem cuttings, expanded stem cuttings, finished blended tobacco cuttings, etc. Its working principle is to put the corresponding sample to be measured into a measuring container, then apply a certain pressure to the sample to be measured, and reflect its filling value according to the deformation amount of the sample to be measured.

[0003] Among them, the precision requirement for the pressure head used to apply pressure is relatively high. Generally speaking, it is necessary to control the lower end face of the pressure head to be parallel to the bottom surface of the measuring cylinder to ensure the stability of the applied pressure and prevent inaccurate measurement caused by the inclination of the pressure acting surface.

[0004] Especially in the solution where the top and bottom of the measuring cylinder are open and the support platform is used as the base of the measuring cylinder, since the pressure head is a movable part and the support platform is the reference plane, the leveling of the two can only adjust the pressure head to make it parallel to the support platform.

[0005] Therefore, it is necessary to design a pressure head structure that can be leveled to meet the leveling requirements in different scenarios.

[0006] In order to solve the above problems, people have been seeking an ideal technical solution. Content of the Utility Model

[0010] Blind holes with internal threads are provided on the top surface of the pressure head corresponding to each tension bolt, and the bottom surface of the pressure head is a smooth plane;

[0011] The mounting seat is provided with through holes corresponding to each tension bolt, and the mounting seat is provided with threaded holes corresponding to each tightening bolt;

[0012] The tension bolts and the tightening bolts are evenly distributed based on the mounting seat.

[0013] As described above, the pressing head has a structure with a cylindrical inner cavity at the top, the mounting seat is embedded in the cylindrical inner cavity, and the outer peripheral surface of the mounting seat and the inner side wall of the cylindrical inner cavity are in close contact and are both vertically arranged to form a guiding surface.

[0015] As described above, the light holes are circumferentially distributed based on the mounting seat, the screw holes are circumferentially distributed based on the mounting seat, and the light holes and the screw holes are arranged at intervals.

[0016] As described above, the contact surface between the pressing head and the mounting seat is a plane.

[0017] As described above, a connecting rod is installed at the center of the top end of the mounting seat.

[0018] As described above, a flared hole that gradually expands from the top end to the bottom end is provided at the center of the mounting seat. A countersunk head screw is installed in the flared hole. The shape of the nut of the countersunk head screw fits the shape of the flared hole.

Specifically, the pressing head of the utility model is designed as a structure including the assembly of the pressing head and the mounting seat.

[0029] The following further describes the technical solutions of the present utility model in detail through specific embodiments.

[0030] Embodiment 1

[0031] As Figures 1 - 4 shown, a pressure head leveling mechanism of a filling value measuring instrument includes a pressure head 1, a mounting seat 2, a plurality of tightening bolts 3 and a plurality of tightening bolts 4.

[0032] The pressure head 1 is installed on the bottom surface of the mounting seat 2;

[0033] Blind holes 11 with internal threads are provided on the top surface of the pressure head 1 corresponding to the respective tightening bolts 3. The bottom surface of the pressure head 1 is a smooth plane for contacting the material to be measured. At the same time, the bottom surface of the pressure head 1 is parallel to the bottom surface of the measuring cylinder or the bottom surface of the support platform, which can make the applied pressure stable and without deflection, and is beneficial to the detection of the filling value.

[0034] Clear holes 21 are provided on the mounting seat 2 corresponding to the respective tightening bolts 3, and threaded holes 22 are provided on the mounting seat 2 corresponding to the respective tightening bolts 4. In this embodiment, the clear holes 21 are set as stepped holes, and the bolt heads of the tightening bolts 3 are installed in the stepped holes through gaskets; the tightening bolts 4 are directly installed in the threaded holes 22.

[0035] The tightening bolts 3 and the tightening bolts 4 are evenly distributed based on the mounting seat 2.

[0036] Principle of operation description:

[0037] In the assembly relationship between the pressure head 1 and the mounting seat 2, they are connected together by the tightening bolts 3. Generally, the pressure head 1 and the mounting seat 2 can be fully fitted after being firmly fixed by the tightening bolts 3. However, since the pressure head is an overall movable part, there is an assembly error, and the measuring cylinder of the pressure application object or as Figure 7The shown support platform 7 is the reference plane, and it is easy to have an angular deviation after the two are assembled, which is the reason for adjusting the angle of the pressing head 1.

[0038] During specific adjustment, lower the pressing head 1 fully until it abuts against the support platform, and then observe the tilting direction of the pressing head 1. For the tilted side, loosen the tension bolt 3 and screw in the top bolt 4 to lower the tilted part. For the other side, tighten the tension bolt 3 and loosen the top bolt 4 to raise the other side. According to this logic, adjust each tension bolt 3 and top bolt 4 respectively, and test while adjusting until the lower end surface of the pressing head 1 is fully attached to the support platform, and it is considered that the two are adjusted consistently.

[0039] In order to stabilize the connection relationship between the pressing head and the mounting seat, in this embodiment, the pressing head 1 is designed with a structure having a cylindrical inner cavity at the top, the mounting seat 2 is embedded in the cylindrical inner cavity, and the contact surface between the pressing head 1 and the mounting seat 2 is a plane.

[0040] The outer peripheral surface of the mounting seat 2 and the inner side wall of the cylindrical inner cavity are in close contact and are both vertically arranged to form a guiding surface.

[0041] In order to make the adjustment regular, the light holes 21 are circumferentially distributed based on the mounting seat 2, the screw holes 22 are circumferentially distributed based on the mounting seat 2, the light holes 21 and the screw holes 22 are arranged at intervals, and the distribution of the two kinds of holes is balanced, making the adjustment simpler.

[0042] For convenient operation, the top ends of the tension bolt 3 and the top bolt 4 are both provided with internal multi-sided holes, such as internal hexagonal holes, and common internal hexagonal tools can be used for operation.

[0043] Embodiment 2

[0044] As Figure 5 and Figure 6 shown, the main difference between this embodiment and Embodiment 1 is that:

[0045] A connecting rod 5 is installed at the center of the top end of the mounting seat 2.

[0046] A flared hole 23 that gradually expands from the top to the bottom is provided at the center of the mounting seat 2. A countersunk head screw 6 is installed in the flared hole 23. The shape of the nut 61 of the countersunk head screw 6 fits the shape of the flared hole 23. A threaded hole is provided at the bottom end of the connecting rod 5 corresponding to the countersunk head screw 6.

[0047] This installation method can ensure the perpendicularity of the installation of the connecting rod 5 and the mounting seat 2, make the axes of the two coincide, and avoid increasing the tilting error of the pressing head due to the assembly error of the connecting rod 5.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that it is still possible to modify the specific implementation manners of the present utility model or perform equivalent replacements on some technical features; without departing from the spirit of the technical solutions of the present utility model, they should all be covered within the scope of the technical solutions claimed by the present utility model.
