Description

Technical Field

[0001] The present invention relates to the field of cigarette filter rod detection, and particularly to a columnar object clamping mechanism, a device and a cigarette filter rod detection device. Background Art

[0002] In the process of product quality control of hand-rolled cigars, in order to ensure the stability of cigar rolling, it is necessary to measure the circumference of cigars. Since most cigars are hand-rolled, there are many external shapes, such as cylindrical, fusiform, semi-fusiform, etc.; at the same time, there are many diameter specifications for cigars, ranging from a diameter of 5 mm to 30 mm, etc. Therefore, when testing the circumference of cigars, it is a difficult point to clamp and fix cigars of different specifications. Currently, most on the market need to replace relevant spare parts for cigars of different specifications to complete the clamping action, which has disadvantages such as complex operation and low detection efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a columnar object clamping mechanism, which can clamp columnar objects of different diameter specifications without replacing spare parts, and is simple to operate and has high detection efficiency when used for cigarette filter rod or cigar detection.

[0004] To solve the above technical problem, the present invention adopts the following technical solutions:

When the rotating seat rotates, the top of the clamping jaw will move along the arc surface of another clamping jaw, and multiple clamping jaws engage with each other to realize the clamping of the columnar object; when the clamping jaws are in the clamping movement, the outer ring is in a static state; during the clamping movement, the outer ring and the rotating seat are subjected to the pulling force of the tension spring, so that the clamping jaws clamp the columnar object; when the clamping jaws clamp the columnar object, the outer ring will rotate simultaneously with the rotating seat.

[0006] As a further improvement of the present invention, the outer ring is provided with an inclined groove. When the clamping jaws need to be loosened, the rotating seat and the outer ring rotate in reverse at the same time. A stop piece is installed on the base. When the stop piece catches the inclined groove of the outer ring, the outer ring stops rotating and the clamping jaws are loosened.

[0007] Furthermore, the clamping jaw is in a shape similar to a triangle, and the 2 through holes are respectively arranged at two inner angles of the clamping jaw in the shape of a triangle.

[0008] Further, there is a rotating piece on each of the upper and lower sides of each jaw. The outer ring is divided into upper and lower layers, and the rotating pieces on both sides of the jaw are respectively connected to the upper layer or the lower layer of the outer ring.

[0009] Further, there are 5 jaws.

[0010] Further, a large pulley is installed on the rotating seat, and the rotating seat is driven to rotate by the large pulley.

[0011] The present invention also discloses a columnar object clamping device, which includes two above-mentioned columnar object clamping mechanisms that are concentrically arranged up and down.

Detailed implementation mode

[0021] As Figure 1 shown, the cylindrical object clamping device in this embodiment is mainly used for concentric clamping of cylindrical objects, and when used for the detection of cigarette filter rods or cigars, it can fix the filter rods and other actions; the device can clamp cylindrical objects with a diameter within 5 mm - 30 mm. Specifically, the cylindrical object clamping device includes a servo motor 1, a motor fixing bracket 2, a coupling 3, a bearing housing 4, a rotating shaft 5, a bearing 6, a small pulley 7, a large pulley 8, a belt 9, and a cylindrical object clamping mechanism 10.

[0022] Among them, the servo motor 1 is fixed on the motor fixing bracket 2, the coupling 3 connects the servo motor 1 and the rotating shaft 5 together, two bearings 6 are respectively installed at both ends of the rotating shaft 5, the bearings 6 are fixed in the bearing housing 4, and the bearing housing 4 is fixed on the motor fixing bracket 1, which can ensure the coaxial requirement of the rotating shaft 5 and the servo motor 1 and make the rotation more stable.

[0023] Two small pulleys 7 are respectively installed at both ends of the rotating shaft 5, the small pulley 7 and the large pulley 8 are connected by a belt 9, and the power of the servo motor 1 is transmitted to the cylindrical object clamping mechanism 10. There are two cylindrical object clamping mechanisms 10, which are concentrically arranged up and down.

[0024] Cooperate Figure 2 、 3 shown, the cylindrical object clamping mechanism 10 includes a base 10 - 1, an outer ring 10 - 2, an outer positioning post 10 - 3, a rotating piece 10 - 4, an inclined slot 10 - 5, a jaw 10 - 6, an inner positioning post 10 - 7, a retaining piece 10 - 8, a bearing 10 - 9, a rotating seat 10 - 10, a tension spring 10 - 11, an outer ring tension spring mounting hole 10 - 12, and a rotating seat tension spring mounting hole 10 - 13.

[0025] Among them, the base 10 - 1 and the rotating seat 10 - 10 are connected and fixed by two bearings 10 - 9, the rotating seat 10 - 10 is located inside the base 10 - 1, the large pulley 8 is fixed on the rotating seat 10 - 10, and when the servo motor 1 works, under the transmission of the belt 9 and the large pulley 8, the rotating seat 10 - 10 rotates.

[0026] The rotating base 10-10 is provided with 5 pin holes, and 5 clamping jaws 10-6 are respectively installed on the rotating base 10-10 through the inner positioning posts 10-7. The clamping jaws 10-6 are triangular in shape, and 2 through holes are provided at two inner angles of the triangular clamping jaws. One of the through holes is connected to the rotating base 10-10 through the inner positioning post 10-7, and the other through hole is connected to one end of the rotating piece 10-4 through the inner positioning post 10-7; the other end of the rotating piece 10-4 is connected to the outer ring 10-2 through the outer positioning post 10-3, and the outer ring 10-2 is located between the base 10-1 and the rotating base 10-10.

[0027] The outer ring 10-2 and the rotating base 10-10 are connected by a tension spring 10-11 and bear the pulling force of the tension spring 10-11. Among them, the rotating base 10-10 is provided with a rotating base tension spring mounting hole 10-13, and at the same time, the outer ring 10-2 is provided with an outer ring tension spring mounting hole 10-12. The two ends of the tension spring 10-11 are respectively installed in the outer ring tension spring mounting hole 10-12 and the rotating base tension spring mounting hole 10-13.

[0028] There is one rotating piece 10-4 on each of the upper and lower sides of each clamping jaw 10-6. The outer ring 10-2 is divided into upper and lower layers. The rotating pieces 10-4 on both sides of the clamping jaw 10-6 are respectively connected to the upper layer or the lower layer of the outer ring. Through the above structural settings, the stability of the movement can be ensured.

[0029] The outer contour of the clamping jaw 10-6 is an arc surface. When the rotating base 10-10 rotates, the top of the clamping jaw 10-6 will move along the arc surface of another clamping jaw 10-6. The 5 clamping jaws 10-6 mesh with each other to realize the clamping of all cylindrical objects within the range of 5 mm - 30 mm in diameter.

[0030] When the clamping jaw 10-6 performs the clamping movement, the outer ring 10-2 is in a static state; when the clamping jaw 10-6 clamps, the rotating base 10-10 and the outer ring 10-2 are subjected to the pulling force of the tension spring 10-11 to ensure that the clamping jaw 10-6 holds the cylindrical object in a clamped state; when the clamping jaw 10-6 clamps the cylindrical object, the outer ring 10-2 will rotate simultaneously with the rotating base 10-10; there is an inclined groove 10-5 on the outer ring 10-2. When the clamping jaw 10-6 needs to be loosened, the servo motor 1 reverses, and the rotating base 10-10 and the outer ring 10-2 reverse simultaneously. A stop piece 10-8 is installed on the base 10-1. When the stop piece 10-8 catches the inclined groove 10-5 of the outer ring, the outer ring 10-2 stops rotating, the clamping jaw 10-6 loosens, and the cylindrical object falls freely. The actions of clamping and loosening the cylindrical object are completed.

[0031] The above cylindrical object clamping device and the cylindrical object clamping mechanism can be directly applied to the cigarette filter rod detection device as the clamping component in the cigarette filter rod detection device, with simple operation and high detection efficiency, and are suitable for popularization and application.
