The thickness measuring device provided by the embodiment comprises a rack main body, a pivot shaft, a floating assembly, a driving mechanism, a plate member, a Hall sensor, an elastic sheet extension part, an elastic sheet main body and a pressing plate. The connection relationship and the operation principle of the above components will be described in detail below.

The housing main body 1 serves to support the pivot shaft 3, and in an embodiment, the housing main body 1 may mainly include a first support member, a second support member, and a third support member, all of which may be formed substantially in a plate shape, and the first support member and the third support member may face each other, and the second support member may be connected therebetween. Referring to fig. 1 and 2, both ends of the pivot shaft 3 may be detachably supported by the first support member and the third support member, respectively, specifically, both ends of the pivot shaft 3 may be formed into a substantially plate shape through a material removing process or a molding process, and the pivot shaft 3 is fixed to the frame body 1 by penetrating such plate-shaped end portions through screws, so that the pivot shaft 3 is fixed relatively reliably.

The number of the floating assemblies 4 can be preferably 12, and the floating assemblies 4 in the number can ensure that the thickness measuring device can be suitable for more detection occasions, and meanwhile, the whole volume of the thickness measuring device is reasonable. Referring to fig. 3, the floating assembly 4 includes the pivot portion 41, and the pivot portion 41 may be formed in a cylindrical shape, that is, 12 pivot portions 41 are sequentially sleeved on the pivot shaft 3, and are defined between two limiting members (for example, two sheet-shaped members clamped on the outer side of the pivot shaft 3) installed on the outer side of the pivot shaft 3, so that the pivot portion 41 can pivot around the axis (hereinafter, referred to as a first axis) of the pivot shaft 3, and the floating assembly 4 can be installed and removed in a convenient manner.

The first axis may extend horizontally during operation of the thickness gauge, and in connection with fig. 4 and 5, the floating assembly 4 further comprises a first beam section 42 and a second beam section 43. The first beam portion 42 extends outwardly from the outer side of the pivot portion 41 to form a free end of the first beam portion 42, the free end of the first beam portion 42 is defined by a first surface 42a (i.e. the extension of the free end of the first beam portion 42 is stopped by the first surface 42a, the same applies below), and the first beam portion 42 is defined by a second surface 42b and a third surface 42c, respectively, in the direction of the pivot portion 41. Referring now particularly to fig. 5, fig. 5 shows a left side view of the float assembly 4, the axis of the bore portion of the cylindrical pivot portion 41 being perpendicular to the page in this view, so that the direction in which the pivot portion 41 pivots corresponds to the horizontal direction in fig. 5.

Referring to fig. 2 and 5, the second beam portion 43 may extend from the second surface 42b in a direction away from the third surface 42c, the mounting shaft portion 44 may be connected to the second beam portion 43, and an axial direction of the mounting shaft portion 44 may be parallel to an axial direction of the hole portion, so that the wheel member 45 may be mounted to the mounting shaft portion 44. In an embodiment, the wheel member 45 may include two bearings 45a respectively mounted at both ends of the mounting shaft portion 44, and outer side portions of outer races of the two bearings 45a are coplanar, thus forming the outer side portion of the wheel member 45, ensuring that the member to be measured passes under the wheel member 45 in such a manner as to be uniformly abutted against the outer side portions of the wheel member 45. Further, the use of the bearing 45a directly as a component forming the wheel member 45 is advantageous in reducing resistance to rotation of the wheel member 45 about the mounting shaft portion 44.

With continued reference to fig. 4 and 5, the float assembly 4 further includes a mounting boss 46 and a mating boss 48. Specifically, the mounting protrusion 46 may be connected to the first surface 42a and the third surface 42c of the first beam portion 42, and the mounting protrusion 46 may be defined by a fourth surface 46a that is farther from the pivot portion 41 than the first surface 42a in the vertical direction, and by a fifth surface 46b that is farther from the wheel member 45 and a sixth surface 46c that is closer to the wheel member 45 in the pivoting direction of the pivot portion 41.

In an embodiment, the mounting protrusion 46 may be formed in a shape of a concave hexagonal prism, and particularly, referring to fig. 5, the bottom surface of the mounting protrusion 46 is formed in a shape of "L", and in fig. 5, the "concave" portion of the bottom surface thereof is formed of two surfaces perpendicular to each other, a surface extending in the vertical direction in fig. 5 is connected to the third surface 42c, and a surface extending in the horizontal direction in fig. 5 is connected to the first surface 42 a.

And the surface of the bottom surface of the mounting projection 46 that is located lowermost in fig. 5 is a fourth surface 46a, and the fourth surface 46a may be mounted with a dust removing member 47. Referring here in particular to fig. 4, the dust removing member 47 may be detachably mounted to the fourth surface 46a by screws. The dust removing member 47 is provided in conformity with the above-described wheel member 45, since the wheel member 45 includes two bearings 45a separated from each other in the axial direction in the present embodiment, the dust removing member 47 is correspondingly formed with two free end portions to perform the dust removing operation to the outer side portions of the outer rings of the two bearings 45a, respectively.

As a preferred embodiment, the dusting member 47 may be formed substantially in the shape of a "U", which facilitates assembly in one go and also facilitates simultaneous positioning of the two free ends of the dusting member 47. Further, the width of both free end portions of the dust removing member 47 may be the same as the width of the outer side portion of the outer ring of the bearing 45a to ensure the dust removing effect.

The dust removing member 47 may be formed of a sheet-shaped white steel material in the above shape, which has high elasticity. Taking one free end portion of the dust removing member 47 as an example, referring to fig. 5 herein, when viewed from the perspective of fig. 5, the plane in which the dust removing member 47 is located actually intersects the outer side portion of the outer ring of the bearing 45a, i.e., the dust removing member 47 is located slightly higher than the lowest point of the outer ring of the bearing 45a, and the free end portion is in contact with the outer side portion of the outer ring of the bearing 45 a. The elasticity of the existing dust removal component is low, the existing dust removal component is in contact with the outer ring of the bearing for a long time, and micro deformation occurs, so that the upper side part of the free end part of the dust removal component protrudes after micro deformation, and the upper side part of the free end part of the dust removal component is in closer contact with the outer ring of the bearing, and excessive heat is generated, and the micro deformation is further aggravated. In contrast, in the working process of the high-elasticity dust removing component 47 of the present embodiment, the free end portion of the dust removing component 47 is deformed by heat so as to force the dust removing component 47 to deform downward in the orientation shown in fig. 5, so as to compensate for the deformation, and the position of the upper side portion of the free end portion of the dust removing component 47 is always kept unchanged along with the rotation of the wheel component 45, thereby avoiding the occurrence of overheating in the prior art, prolonging the service life of the dust removing component 47, and also improving the dust removing effect.

Further referring to fig. 5, the bottom surface of the mounting projection 46, the left side surface is a fifth surface 46b, and the right side surface is a sixth surface 46 c. The fitting projection 48 may be connected to the fifth surface 46b of the mounting projection 46, and specifically, the fitting projection 48 may be formed in a substantially rectangular parallelepiped shape having one side surface connected to the fifth surface 46b, and a surface of the fitting projection 48 which abuts against the spring plate extension 7a described below is defined as a seventh surface 48a, and the seventh surface 48a faces away from the fifth surface 46 b. The seventh surface 48a may be formed as a curved surface having an axis parallel to the first axis so as to more smoothly form a fit with the spring extension 7a described below.

With reference to fig. 6 and 7, the spring main body 7b is connected to the spring extensions 7a, which are the same in number as the floating assembly 4, so as to form an approximately "comb" structure, that is, the 12 spring extensions 7a are all connected to one side edge of the spring main body 7 b. Referring to fig. 6 in particular, taking one of the elastic sheet extending portions 7a as an example, the width of the free end of the elastic sheet extending portion 7a may be greater than the width of the middle portion of the elastic sheet extending portion 7a, so that the free end of the elastic sheet extending portion 7a can be adapted to the width of the engaging protrusion 48 in the extending direction of the first axis, and it is ensured that the two are engaged stably. The spring main body 7b can be mounted on the second support part by the pressing plate 7c via screws, which facilitates the detachment of the spring main body 7b and the spring extension part 7 a.

Referring further to fig. 7, fig. 7 shows a state in which the floating assembly 4 is not floating (i.e., the thickness measuring device is not operated), and the engagement protrusion 48 engages with the free end of the spring extension 7 a. The mating protrusion 48 forces the spring extension 7a to undergo a first amount of elastic deformation with respect to the vertical direction in a direction away from the float assembly 4 (i.e., to the left in fig. 7). In the state that the floating assembly 4 floats, the thick member to be measured passes under the wheel member 45 in a manner of abutting against the outer side portion of the wheel member 45, the wheel member 45 floats and is lifted upwards, and then pivots around the first axis of the pivot shaft 3, so that the matching convex portion 48 pivots downwards, and the upper deformation amount of the spring extension portion 7a in the original deformation direction is forced to be changed into the second elastic deformation amount. The second elastic deformation amount is larger than the first elastic deformation amount, so that after the thickness measuring component passes through the lower part of the wheel component 45, the elastic sheet extension part 7a can be matched with the convex part 48 under the action of restoring force, so that the wheel component 45 is quickly reset, the efficient reset of the wheel component 45 is realized, the response time of the thickness measuring device is effectively shortened, and the working efficiency of the equipment is further improved.

As described above, the thick member to be measured passes under the wheel member 45 against the outer side portion of the wheel member 45, which is achieved by the driving mechanism. Referring to fig. 8, fig. 8 is a schematic view showing the engagement of the driving mechanism and the 12 floating assemblies 4, but fig. 8 is not a schematic drawing of the thickness measuring apparatus as seen from a top view, because the driving roller member 81 is disposed below the 12 floating assemblies 4, and the driving roller member 81 is hardly seen when the thickness measuring apparatus is seen from a top view, and fig. 8 is a schematic drawing made to highlight the engagement relationship of the driving roller member 81 and the wheel member 45.

The driving mechanism comprises driving roller members 81 and a driving shaft 8, wherein the driving roller members 81 can be understood as being penetrated by the coaxial driving shaft 8 to form a whole, the manufacturing is convenient, and the abrasion caused by the matching with the wheel members 45 is avoided through quenching treatment. The drive shaft 8 may also be supported in the frame body 1, the axis of which may be defined as a second axis, obviously parallel to the above-mentioned first axis, the drive shaft 8 being drivable via a motor such that the drive roller member 81 rotates synchronously with the drive shaft 8.

As mentioned above, the drive roller member 81 is disposed below the wheel member 45 with the outer sides of the two in contact, so that the drive roller member 81 can drive the wheel member 45 to rotate in the direction opposite to the rotation direction of the drive roller member 81, thus enabling a thick member to be measured, such as a bill, to pass therebetween.

On the basis of the above-described features, the present embodiment converts the thickness of the bill into the floating amount when the wheel member 45 pivots, and determines the thickness of the bill by measuring the floating amount. To this end, the float mechanism further includes a positioning assembly, which is configured to move in a position before and after pivoting about the first axis.

With reference to fig. 4 and 5, the positioning assembly may be provided at an outer side of the pivot portion 41 and include the third beam portion 5 and a positioning member. The third beam portion 5 may extend from an outer side portion of the pivot portion 41 outward in a radial direction of the pivot portion 41 to form a free end of the third beam portion 5. The positioning member may be formed as a magnet 51 and embedded in the free end of the third beam portion 5. The amount of fluctuation in the position of the pivot portion 41 before and after pivoting is amplified by the third beam portion 5, and the movement of the magnet 51 at the free end of the third beam portion 5 can be detected by the measuring mechanism, specifically, the height of the magnet 51 can be lowered as the pivot portion 41 pivots when the bill passes under the wheel member 45.

Referring to fig. 7, the third beam portion 5 may be in a horizontal or substantially horizontal position in a state in which the thickness measuring device is not in operation. The rack body 1 is further provided with a plate member 2 facing the free end of the third beam portion 5, the plate member 2 may be provided with hall sensors 6 (fig. 1, 3, 7, and 8) corresponding to the 12 magnets 51 one to one, the hall sensors 6 may be electrically connected to a measuring component provided in the plate member 2, and the hall sensors 6 amplify the displacement of the magnets 51, sense the change of a voltage signal, and then accurately measure the thickness of the paper money via the measuring component. As a preferred embodiment, the plate member 2 and the measuring assembly may be formed as a measuring circuit board, and the hall sensor 6 may be detachably mounted to the measuring circuit board for easy maintenance and removal. The Hall sensor 6 is used as a detection element, so that the detection precision is greatly improved.

In addition, based on the characteristics described above, the thickness measuring device is simple in structure, adopts a modular design, and can be used as a module to be conveniently installed in currency conveying channels of various types, so that the internal space of the whole machine is saved, and the floating assembly 4 can be detached and maintained independently, so that the use is more convenient.

The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, and all changes that can be made in the details of the present application and the equivalents thereof, or directly or indirectly applied to other related technical fields, without departing from the spirit of the present application are intended to be embraced therein.
