Technical Field

[0001] The utility model belongs to the technical field of spinning paper tube processing equipment, and particularly relates to a device for detecting the strength of the large and small openings of a spinning paper tube. Background Art

[0002] The existing technology has the following problems:

[0003] The special spinning paper tube is used as the winding core tube of the yarn. The part with a large diameter is commonly known as the "large opening", and the part with a small diameter is commonly known as the "small opening". Currently, with the improvement of equipment and process technology, the speed of the spinning machine can reach 1800 - 2000 r / min, and the yarn is also developing towards high-count yarn. This development trend requires higher and higher compressive strength for the spinning paper tube;

[0004] Generally, the compressive tester only detects the strength of the tube body of the spinning paper tube and cannot separately detect the strength of the large and small openings of the paper tube. The spinning of the tube yarn on the spinning machine relies on two chucks and a roller to drive the paper tube for spinning. The strength of the large and small openings of the spinning paper tube is crucial for the speed increase of the spinning machine. Therefore, it is necessary to independently detect the compressive strength of the large and small openings of the spinning paper tube to ensure that the quality of the paper tube meets the requirements of downstream customers.

[0005] To solve the above problems, a device for detecting the strength of the large and small openings of a spinning paper tube is proposed in this application. Content of the Utility Model

The tray support includes a cylinder, a connecting column welded on the outer side wall of the cylinder, and a square tube welded on the end face of the connecting column. The square tube and the square steel are mutually adapted;

[0010] A tray is inserted into the cylinder of the tray support, and a weight is placed at the middle position of the top of the tray.

[0011] As an optimization of a device for detecting the strength of the large and small openings of a spinning paper tube according to the present utility model, the paper tube is a conical hollow tubular structure;

[0012] The mold is a "U"-shaped plate-like structure, and a groove adapted to the taper and length of the paper tube is provided on the surface.

[0013] As an optimization of a device for detecting the strength of the large and small openings of a spinning paper tube according to the present utility model, a second threaded hole is provided on a side surface of the square tube away from the connecting column, a fixing member is threadedly connected in the second threaded hole, an end surface of the fixing member penetrates through the second threaded hole and contacts the square steel, and the tray support is fixedly connected to the square steel of the support rod through the square tube, the second threaded hole and the fixing member.

[0033] A tray 5 is inserted into the cylinder of the tray support 4, and a weight 8 is placed at the middle position of the top of the tray 5.

[0034] In this embodiment: Place the paper tube 7 on the upper surface of the mold 2. Sleeve the support rod 3 on the first optical axis on the surface of the base 1 (wherein, a structure for increasing the friction force, such as a silicone pad, can be provided between the support rod 3 and the first optical axis to increase the friction force between the support rod 3 and the first optical axis, ensuring the stability of the square steel of the support rod 3 and making it not easy to swing back and forth), which is convenient for later detection. Sleeve the tray support 4 on the square steel of the support rod 3 through a square tube and move and adjust its position. This is a rough position adjustment. Insert the second optical axis of the tray 5 into the cylinder of the tray support 4, and then slide the tray support 4 again to accurately adjust the position, ensuring that the bottom of the second optical axis of the tray 5 is in place in contact with the end of the paper tube 7, that is, independently perform the compressive strength test on the large and small openings of the paper tube 7. Rotate the fixing member 6 through the second threaded hole to squeeze the square steel, ensuring the stability of the tray support 4. Finally, place the weight 8 at the middle position on the square plate surface of the tray 5, and gradually increase the weight 8 to perform the compressive strength test and surface hardness test on the paper tube 7 with different weights, ensuring that the quality of the paper tube 7 meets the requirements of downstream customers.

[0035] It should be noted that: In this embodiment, both the base 1 and the mold 2 are made of carbon steel, and both the support rod 3 and the tray support 4 are made of stainless steel.

[0036] In an alternative embodiment, the paper tube 7 is a conical hollow tubular structure;

[0037] The mold 2 is a "U"-shaped plate-like structure, and its surface is provided with grooves that are mutually adapted to the taper and length of the paper tube 7.

[0038] In this embodiment: The paper tube 7 is in a pagoda shape. The "U"-shaped plate-like structure of the mold 2 is convenient for placing the paper tube 7, and the adapted grooves ensure the stability of the paper tube 7 during placement and the later strength detection process, making it not easy to shake and ensuring the detection effect.

[0039] It should be noted that: In this embodiment, the taper of the paper tube 7 is 4°32′.

[0040] In an alternative embodiment, a second threaded hole is provided on the side surface of the square tube away from the connecting column.

For approximate position adjustment, insert the second optical axis of the tray 5 into the cylinder of the tray support 4, slide the tray support 4 again, and precisely adjust the position to ensure that the bottom of the second optical axis of the tray 5 is in place in contact with the end of the paper tube 7, that is, perform independent compressive strength tests on the large and small openings of the paper tube 7. Rotate the fixing member 6 through the second threaded hole to squeeze the square steel to ensure the stability of the tray support 4. Finally, place the weight 8 at the middle position on the surface of the square plate of the tray 5 and gradually increase the weight 8.
