Description

Technical Field

[0001] The utility model relates to the technical field of webbing metering, and particularly relates to a webbing metering device. Background Art

[0002] A webbing refers to a narrow fabric or tubular fabric made of various yarns. There are many varieties of webbing fabrics, which are widely used in various industrial sectors such as clothing, shoe materials, luggage, industry, agriculture, military supplies, and transportation. During the production process of webbing, the webbing is often wound up, and the amount of webbing wound is measured. For example, the patent with the application number CN202222290642.2 discloses a metering device for webbing production. This device can stop winding in time after the webbing winding metering reaches the standard, and has good practicability.

[0003] In the above design, there is a lack of a corresponding flattening structure. It is very likely that the webbing will be wound or kinked around the winding roller, which brings great inconvenience to users.

The flattening plate 203 is slidably connected to the vertical guide rods 204. Both ends of the vertical guide rods 204 are connected to the mounting seat 201.

[0031] See Figures 2-3 As shown, the metering mechanism 4 is located at the right end of the winding mechanism 3. The metering mechanism 4 is connected to the substrate 102. The metering mechanism 4 includes a mounting plate 401, a pressing plate 404 and a contact plate 406. The rear end of the mounting plate 401 is connected to the front end of the substrate 102.

[0032] In an embodiment of the present utility model, for the webbing metering device with the above structure, first lift the flattening plate 203, so that the webbing passes through the flattening plate 203 from the threading groove 202 downward, release the flattening plate 203, and connect the webbing to the winding roller 302, and start the webbing winding operation;

[0033] Control the winding motor 305 to work through the controller 5. The rotating shaft 301 can be driven to rotate under the action of the coupling 306. The rotating shaft 301 can drive the winding roller 302 to rotate under the action of the key 303. The rotation of the winding roller 302 can realize the winding operation of the webbing. In this process, when the webbing passes through the flattening plate 203, under the action of the pressing spring 205, the flattening plate 203 presses the webbing, and the webbing can be flattened during the winding operation.

[0034] During the winding process of the winding roller 302, the winding roller 302 gradually becomes thicker. The gradual thickening of the winding roller 302 will push the contact plate 406 to move to the right. The rightward movement of the contact plate 406 will, under the action of the return spring 405, push the pressing plate 404 to move to the left. The leftward movement of the pressing plate 404 will contact the pressure sensor 403. The pressure sensor 403 detects the pressure information of the pressing plate 404 and feeds the information back to the controller 5. When the winding amount of the webbing on the winding roller 302 reaches the standard, the pressure information on the pressure sensor 403 reaches the standard, completing the metering operation of the webbing winding. After the webbing winding metering reaches the standard, the winding roller 302 can be removed and a new winding roller 302 can be replaced to perform a new round of webbing winding metering operation.

[0035] It should be noted that the controller 5 controls the operation of the winding motor 305 using the prior art, and the controller 5 controls the operation of the pressure sensor 403 using the prior art.

[0036] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
