Description

Technical Field

[0001] The utility model relates to the field of counters, in particular to a structure of a contact counter. Background Art

[0002] A counter is an electronic device for measuring length, which is widely used in fields and industries that require measuring the length of products. It can be classified into an electronic counter, a laser counter, a roller counter, etc. according to its functions.

[0003] Among them, the roller counter mainly includes a counting wheel, an encoder and a mounting bracket. The counting wheel is rotatably connected to the mounting bracket. In actual use, the counting wheel abuts against the measured object. As the measured object is continuously conveyed, the counting wheel rotates continuously. The encoder converts the mechanical motion signal of the rotation of the counting wheel into an electrical signal to realize the measurement of the length of the object. However, in actual use, when the end of the measured object first contacts the counting wheel during the conveying process, it will cause an impact on the counting wheel, and then it is easy to damage the surface of the counting wheel, which affects the subsequent measurement. At the same time, it also leads to frequent replacement of the counting wheel. Summary of the Utility Model

[0004] In order to further reduce the damage of the counting wheel, the present application provides a structure of a contact counter.

[0005] The present application provides a structure of a contact counter, adopting the following technical solutions:

[0006] A structure of a contact counter includes a mounting bracket and a counting wheel, and further includes a fixing bracket. The mounting bracket includes a mounting strip and a swing arm. The counting wheel is rotatably connected to the mounting strip. The middle part of the mounting bracket is rotatably connected to the fixing bracket. An abutting wheel is rotatably connected to the end of the swing arm. A reset member for driving the mounting bracket to rotate and reset so that the bottom of the abutting wheel is lower than the bottom of the counting wheel is arranged on the fixing bracket.

[0007] Optionally, the reset member includes a reset spring. One end of the reset spring is fixed to the mounting strip, and the other end is fixed to the fixing bracket.

[0008] Optionally, the fixing bracket includes a top bracket and a base. The base is detachably connected to the top bracket. The rotation mounting point of the mounting bracket is on the base.

[0009] Optionally, the base and the top bracket are fixedly connected by bolts. Fixing holes for connecting and mounting the base are formed on the top bracket. The fixing holes are waist-shaped holes.

[0010] Optionally, the top bracket is strip-shaped and has a bent portion.

[0011] Optionally, the abutting wheel is a wear-resistant rubber wheel and is detachably connected to the swing arm.

[0012] Optionally, the swing arm is detachably connected to the mounting strip, and a plurality of mounting holes are provided on the mounting strip and distributed circumferentially.

[0013] Optionally, the angle between the swing arm and the mounting strip is an obtuse angle, and the length of the swing arm is less than the length of the mounting strip.

[0014] In summary, the present application includes at least one of the following beneficial technical effects:

[0015] 1. Through the design of the swing arm, the abutting wheel and the reset member, the starting side of the measured object does not contact and impact the length measuring wheel during the conveying process. At this time, the length measuring wheel is located above the measured object. It is not until the side wall of the measured object contacts the abutting wheel that the swing arm and the mounting strip are driven to rotate, so that the length measuring wheel abuts on the surface of the measured object to start the measurement. After the detection is completed, the length measuring wheel is lifted again under the action of the reset member, effectively preventing the length measuring wheel from being easily damaged by impact, making the length measuring wheel more durable and not easily damaged, and can continuously maintain good detection accuracy;

[0016] 2. The top frame is strip-shaped and has a bent portion. The top frame takes into account both the installation strength and elasticity, so that while the top frame serves as an installation function, it can also play a partial elastic reset function for the abutting wheel;

[0017] 3. The abutting wheel is a wear-resistant rubber wheel with better wear resistance, which improves the service life, and the abutting wheel can be replaced separately. Description of the Drawings

[0022] The following further describes the present application in detail Figure 1-2 in conjunction with the attached drawings.

[0023] A contact type length measuring device structure, as shown in Figure 1 and Figure 2As shown in the figure, it includes a fixing frame 1, a mounting frame 2 and a length measuring wheel 3. The mounting frame 2 is L-shaped and includes a mounting strip 4 and a swing arm 5. The L-shaped corner of the mounting frame 2 is rotatably connected to the fixing frame 1. The length measuring wheel 3 is rotatably connected to one end of the mounting strip 4 away from the rotation point. A contact wheel 6 is rotatably connected to one end of the swing arm 5 away from the rotation point. An encoder 7 is provided at the rotation connection of the length measuring wheel 3. A reset member for connecting the two is provided between the mounting frame 2 and the fixing frame 1. The reset member specifically uses a reset spring 8. One end of the reset spring 8 is fixed to the fixing frame 1, and the other end is fixed to the mounting strip 4. The reset member is used to drive the mounting frame 2 to reset to a state where the bottom of the length measuring wheel 3 is higher than the bottom of the contact wheel 6. In other embodiments, the reset member can also use a reset torsion spring.

[0024] In this embodiment, it is specifically installed above the conveying table 9. The conveying table 9 includes a plurality of conveying rollers distributed at intervals. Taking the measured object 10 as a stainless steel coil as an example, the measured object 10 is continuously unrolled under the action of the conveying table 9 and its front end is continuously conveyed forward. In the initial state, the bottom of the length measuring wheel 3 is higher than the surface of the measured object 10 on the conveying table 9, and the bottom of the contact wheel 6 is lower than the surface of the measured object 10 on the conveying table 9. In this way, the initial end of the measured object 10 passes under the length measuring wheel 3 until it contacts the contact wheel 6, and drives the swing arm 5 to rotate around the rotation point. The mounting strip 4 rotates accordingly until the length measuring wheel 3 abuts on the surface of the measured object 10. At this time, the continuous conveyance of the measured object 10 causes the length measuring wheel 3 to rotate continuously. The rotation signal is converted by the encoder 7 and an electronic signal is output to realize the detection of the length.

[0025] In this way, during the conveyance of the measured object 10, the starting side does not contact the length measuring wheel 3 until the front side wall of the measured object 10 contacts the contact wheel 6 and drives the swing arm 5 and the mounting strip 4 to rotate, so that the length measuring wheel 3 abuts on the surface of the measured object 10 and starts to measure. After the detection is completed, the length measuring wheel 3 is lifted again under the action of the reset member, effectively preventing the length measuring wheel 3 from being easily damaged by impact, making the length measuring wheel 3 more durable and not easily damaged, and can continuously maintain the detection accuracy well.

[0026] As Figure 1 and Figure 2 shown in the figure, the fixing frame 1 includes a top frame 11 and a base 12. The rotation point of the mounting frame 2 is provided on the base 12. The top of the base 12 is fixedly connected to the top frame 11. The base 12 and the top frame 11 are detachably connected by bolts and nuts. Fixing holes for connecting and installing the base 12 are provided on the top frame 11. The fixing holes are kidney-shaped holes, so that the installation position of the base 12 can be finely adjusted, and thus the position of the rotation point of the mounting frame 2 can be synchronously finely adjusted.

[0027] As Figure 1 and Figure 2As shown, the top frame 11 is in the shape of a strip and has a bending portion 13 . The top frame 11 is relatively thin and has both installation strength and elasticity. Thus, the top frame 11 not only has an installation function, but also can play a partial elastic reset role for the abutment wheel 6 .

[0028] like Figure 1 and Figure 2 As shown, the abutment wheel 6 is a wear-resistant rubber wheel, and the abutment wheel 6 is detachably connected to the swing arm 5. Specifically, the detachable connection can be achieved by means of a retaining spring or a bolt with a nut. The abutment wheel 6 is a wear-resistant rubber wheel with better wear resistance, which increases the service life, and the abutment wheel 6 can be replaced separately.

[0029] like Figure 1 and Figure 2 As shown, the swing arm 5 is detachably connected to the mounting bar 4, and a plurality of mounting holes 14 evenly distributed around the circumference of the rotation point are opened on the mounting bar 4. During the actual installation process, the swing arm 5 is connected and fixed through each mounting hole 14. During installation, the corresponding mounting hole 14 can be selected for connection as needed. In this way, the installation angle of the swing arm 5 can be adjusted, and the initial height of the abutment wheel 6 can be adjusted simultaneously, which can meet the measurement of more objects with different thicknesses to be measured and has better applicability.

[0030] like Figure 1 and Figure 2 As shown, in this embodiment, the angle between the swing arm 5 and the mounting bar 4 is an obtuse angle, and the length of the swing arm 5 is less than the length of the mounting bar 4. In this way, during the rotation of the swing arm 5, the height of the meter wheel 3 changes greatly to better meet the use requirements.

[0031] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
