Abstract
Description
Technical Field
[0001] The utility model belongs to the field of medicine packaging and processing machinery, and in particular relates to a torque detection device for caps with special shapes. Background Art
[0002] In the automated production line of the pharmaceutical aluminum ointment tube manufacturing industry, the plastic caps are automatically capped by the capping machine. The tightness of the caps needs to be controlled within a standard range. If the caps are too tight, the caps are prone to cracking under stress for a long time; if the caps are too loose, the caps are prone to fall off during the later transportation and filling process. Therefore, the tightness of the caps on aluminum tube products needs to be determined by measuring whether the size of the cap removal torque can meet the set standard requirements. For special plastic caps with special shapes such as the CM150101 cap with internal threads at the small diameter end and the caps with opposite diameters at the large and small ends after the aluminum tube is capped, the general torque measuring device cannot meet the requirements to accurately measure the cap removal torque. It is necessary to design a special torque detection device based on the characteristics of the caps. Summary of the invention
[0003] The utility model aims to solve the above problems and provides a torque detection device for a cap with a special shape, which is suitable for a special-shaped CM150101 cap.

[0006] A guide cone is provided on the positioning column;
[0007] The guide cone and the positioning column are provided with clearance holes;
[0008] The measuring head body is provided with a plurality of positioning platforms; the positioning platforms are evenly distributed on the bottom of the positioning column in a circumferential manner; the positioning platforms are arranged at equal intervals; and positioning slots are formed between adjacent positioning platforms;
[0009] A connecting rod is provided at the bottom of the measuring head body;

[0011] Furthermore, in the torque detection device for a cap of a special shape described in the utility model, the guide cone is in a truncated cone shape; the truncated cone-shaped guide cone plays a role of positioning and guiding during torque detection, facilitating the detection operation.
[0012] Furthermore, in the torque detection device for a cap of a special shape described in the utility model, the clearance hole is a circular blind hole; the diameter of the clearance hole is larger than the diameter of the cap thorn cone; the depth of the clearance hole is larger than the length of the cap thorn cone. The size setting of the clearance hole can prevent the cap from being blocked in any way during the connection with the measuring head body, avoid affecting the measurement results, and improve the detection efficiency.
[0013] Furthermore, in the torque detection device for a special-shaped cap of the utility model, the connecting rod is in the shape of a square prism. By setting the connecting rod as a square prism, the connection stability between the measuring head body and the torque meter is increased, thereby improving the accuracy of the measurement result of the torque meter.
[0014] The torque detection device for a cap of a special shape described in the utility model has a guide cone arranged on a measuring head body to guide the connection between the cap and the detection device; a clearance hole is arranged to facilitate the cap to avoid a cap thorn cone arranged in the cap when the cap is connected to the detection device; a positioning platform and a positioning slot are used to position and fix the cap during rotation, thereby realizing torque detection; the detection device described in the utility model has a small size, a light weight, and is simple to operate; deviations in human operating techniques and actions do not affect the accuracy of measurement data, and is suitable for popularization and application.

[0019] The torque detection device for the special-shaped cap 9 of the present invention is described in detail below through the accompanying drawings and embodiments.
[0020] like Figure 1 As shown, the torque detection device for the special-shaped cap 9 described in this embodiment includes a measuring head body 5; a positioning column 3 is provided on the measuring head body 5; a guide cone 1 is provided on the positioning column 3; and a clearance hole 2 is provided in the guide cone 1 and the positioning column 3; Figure 2As shown, four positioning platforms 4 are arranged on the measuring head body 5; the positioning platforms 4 are evenly distributed in a circle at the bottom of the aforementioned positioning column 3; the positioning platforms 4 are arranged at equal intervals; positioning slots 7 are formed between adjacent positioning platforms 4; a connecting rod is arranged at the bottom of the measuring head body 5; the center lines of the guide cone 1, the clearance hole 2, the positioning column 3, the measuring head body 5 and the connecting rod are coaxially arranged.
[0021] In the disclosed embodiment, the guide cone 1 is in the shape of a truncated cone, and the angle between its cone surface and the horizontal is 53°; the clearance hole 2 is a blind hole in the shape of a circle; the positioning column 3, the positioning platform 4, and the measuring head body 5 are all in the shape of a cylinder; the connecting rod is in the shape of a square prism; the positioning slot 7 is a groove formed by the positioning column 3, the positioning platform 4, and the measuring head body 5.
[0022] When performing torque detection on the special-shaped cap 9, the torque detection device for the special-shaped cap 9 described in the utility model is connected to the torque meter 8; the torque meter 8 is a standard measuring instrument, and the HP-10 of Yinuo Electronics (Taiwan, China) is used in the embodiment disclosed in the present invention to output the torque size. The torque meter 8 is provided with a jack connected to the connecting column 6 of the measuring head body 5 described in this embodiment. When it is necessary to measure the torque between the cap 9 and the aluminum tube, the torque detection device for the special-shaped cap 9 described in this embodiment is fixed to the torque meter 8 through the connecting column 6, and then the aluminum tube connected to the cap 9 is held by hand so that the cap 9 is vertically downward, and the cap 9 is successively put on the measuring head body 5 through the guide cone 1 and the positioning column 3. A boss corresponding to the positioning slot 7 is provided in the cap 9, which is fixed by the positioning table 4 and the positioning slot 7, and then the aluminum tube is screwed counterclockwise. The cap 9 is blocked and fixed by the positioning table 4 and the positioning slot 7 on the measuring head body 5. At the moment the cap 9 is unscrewed, the torque is transmitted to the torque meter 8 through the measuring head body 5. The torque meter 8 senses the size of the torque and displays the specific torque value, which can be read and recorded.
[0023] The obtained torque value is the uncapping torque of the cap 9. If the reading is within the specified uncapping torque standard range, it is judged to be qualified; if it exceeds the standard range, it is judged to be unqualified.
[0024] If it is necessary to continue measuring other sampled aluminum tubes, the torque meter 8 only needs to be reset to display a data value of zero and the above operation can be repeated.
[0025] The torque detection device for the special-shaped cap 9 described in this embodiment is small in size, light in weight, and easy to operate. Deviations in human operation techniques and actions do not affect the accuracy of the measurement data, which effectively solves the problem that the torque of the special-shaped cap 9 is difficult to detect.
