Description

Technical Field

[0001] This utility model relates to the field of short fiber content testing technology, and in particular to a rapid sampling clamp device for short fiber content testing. Background Technology

[0002] The short fiber content of raw cotton or slivers has a significant impact on product quality and production processes. An excessively high short fiber rate leads to reduced yield and lower production efficiency in textile enterprises, and also results in the production of substandard yarns and fabrics. In recent years, short fiber rate testers have been widely used. However, from an overall perspective, the accuracy of experimental data, overall machine stability, and consistency of sampling differences still need improvement. Sampling is crucial in the short fiber rate testing process. Among these, the sampling clamp's sampling difference is a key factor affecting test data. Early methods used parallel motion sampling clamps, but the size and horizontal angle of the sampling clamps varied from machine to machine, and the clamping force and negative pressure suction also differed, making it difficult to effectively control the accuracy of test data and the consistency of sampling differences. Utility Model Content

Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0026] like Figure 1-6 As shown, this utility model provides a rapid sampling clamping device for short fiber rate testing, including: a linear slide module 14 mounted on a frame, a support base plate 1 mounted on the linear slide module 14, a plurality of openable clamping mechanisms 7 provided on the support base plate 1, a conduit assembly 12 for collecting fiber samples 15 after testing provided at the bottom of each clamping mechanism 7, a clamp jaw provided at the end of each clamping mechanism 7, and a comb needle row 16 provided at the entrance of each clamping mechanism 7. The comb needle row 16 and the fiber sample 15 are located on one side of the linear slide module 14, and the linear slide module 14 drives the fixed clamping jaw 6 to move to the fiber sample 15 for sampling.

[0027] Preferably, a vertical plate 2 is mounted on the base plate 1 of the support, and the clamping mechanism 7 is mounted on the vertical plate 2; a cylinder 7-1 for controlling the opening and closing of the clamping mechanism 7 is mounted on one side of the vertical plate 2. The clamping mechanism 7 includes: a fixed clamping jaw 6 mounted on the vertical plate 2, a movable jaw 8 hinged to the fixed clamping jaw 6, the end of the movable jaw 8 being connected to the cylinder 7-1; and a lower jaw 11 mounted at the front end of the fixed clamping jaw 6. The lower jaw 11 is composed of a lower jaw base plate 11-1 and polyurethane 11-2, and the lower jaw 11 can be replaced if the polyurethane 11-2 breaks.

[0028] Furthermore, in this utility model, a cylinder seat 3 is installed on the support base plate 1, the cylinder 7-1 is fixed on the cylinder seat 3, and a clamping plate 7-2 is installed above the cylinder 7-1. The clamping plate 7-2 contacts the inclined surface of the rear end of the movable jaw 8. The movable jaw 8 is connected to the fixed jaw 6 through a spindle 4, and needle roller bearings 5 ​​are installed at both ends of the spindle 4. The movable jaw 8 rotates around the spindle 4 and the needle roller bearings 5.

[0029] In addition, a cotton guide plate 10 is installed on the fixed clamp 6, and a spring 9 is installed on the cotton guide plate 10. The movable clamp 8 is in contact with the spring 9.

[0030] The conduit assembly 12 is connected to the clamping mechanism 7. For example, in this utility model, the first branch pipe 12-1 is a right-angle flange. The right-angle flange 12-1 is connected to the tee connector 12-3 through the suction pipe 12-2. The tee connector 12-3 is connected to the right-angle connector 12-4. The right-angle connector 12-4 is connected to the vacuum negative pressure P.

[0031] A cylinder seat 3 is mounted on the top of the support base plate 1. The cylinder 7-1 is fixed on the cylinder seat 3. A clamping plate 7-2 is installed on the top of the cylinder 7-1. The clamping plate 7-2 is in contact with the rear end of the movable jaw 8.

[0032] The working process of this utility model is as follows:

[0033] The linear slide module 14 is driven by a servo motor 13, and the support base plate 1 drives the fixing clamp 6 to move in a V-shape. a When the speed advances to position 2, the fiber sample 15, the negative pressure suction P between the movable jaw 8 and the fixed jaw 6 pulls the fiber sample 15 down to the jaw 11. The cylinder 7-1 rises H5, and the clamping plate 7-2 pushes the rear end of the movable jaw 8 upward. At this time, the front end of the movable jaw 8 rotates downward to the jaw 11 to clamp the fiber sample 15. At this time, the linear slide module 14 drives the fixed jaw 6 to move at V. b The speed is reversed to position 1. After the fixed clamp 6 picks up the fiber sample 15, the test is carried out. After the test is completed, the cylinder 7-1 is released, and the spring 9 opens the movable jaw 8 and the lower jaw 11 to a height H4. The fiber sample 15 picked up by the lower jaw 11 is recovered along the guide plate 10 through the conduit assembly 12.

[0034] The rear contact surface of the movable jaw 8 is designed to be 86°. When the cylinder 7-1 is released, it has a 4° angle with the clamping plate 7-2. When the cylinder 7-1 is raised to H5, the clamping plate 7-2 pushes the rear end of the movable jaw 8 upward. When the front end of the movable jaw 8 and the lower jaw 11 clamp the fiber sample 15, the rear end of the movable jaw 8 is pressed against the front of the clamping plate 7-2. In order to avoid the sample fiber being missed or pulled out during the sampling process, the clamping force F2 of the movable jaw 8 is at its maximum at this time, and the fiber sample 15 is firmly clamped in the fixed jaw 6.

[0035] Based on the lever principle, the formula for calculating the clamping force F2 during the sampling process of the movable jaw 8 is as follows:

[0036] F2=(F1×L1+F P ×L2-G×L3-F3×L4) / L2

[0037] The fixed suction port 6 has channels a and b. When the cylinder 7-1 is released, the spring 9 opens the movable jaw 8 and the lower jaw 11 by H4, channel a is opened to its maximum, and channel b is closed. At this time, the negative pressure P in channel a is at its maximum, which can neatly suck the fiber sample 15 on the comb needle row 16 into the position of the lower jaw 11. When the cylinder 7-1 is raised by H4, the front end of the movable jaw 8 closes with the lower jaw 11. At this time, channel a is closed and channel b is opened. The negative pressure in the fixed clamp 6 does not affect the testing of the fiber sample 15 that has been clamped.

[0038] To ensure the neatness and consistency of sampling, the fixed jaw 6 and the movable jaw 8 must be opened at least H4 at a time, and the sampling jaws must meet the following force requirements:

[0039] G×L3+F3×L4≧F P ×L2

[0040] The lower jaw 11 consists of a lower jaw base plate 11-1 and a polyurethane 11-2. The lower jaw 11 can be quickly replaced after the polyurethane 11-2 is broken.

[0041] The cylinder 7-1 rises to drive the movable jaw 8 to move. When the movable jaw 8 clamps the fiber sample 15, the cylinder 7-1 experiences the maximum force F1, and the fiber sample 15 is firmly clamped. The fiber sample 15 can be quickly and neatly clamped. The height of the cylinder seat 3 can control the opening size H4 of the movable jaw 8 and the lower jaw 11, as well as the clamping force F2. When the linear slide module moves the fixed jaw forward to the fiber sample, the negative pressure suction generated between the movable jaw and the fixed jaw will pull the fiber sample to the lower jaw position. The cylinder rises to drive the movable jaw to clamp the fiber sample. At this time, the linear slide module drives the fixed jaw to retract, and the fixed jaw clamps the fiber sample. The cylinder releases, and the spring opens the movable jaw and the fixed jaw. The fiber sample clamped by the lower jaw is recovered along the guide plate through the conduit assembly. The cylinder rises to drive the movable jaws to move. When the movable jaws clamp the fiber sample, the cylinder is subjected to the greatest force, and the fiber sample is firmly clamped. The fiber sample can be quickly and neatly clamped. The height of the cylinder seat can control the opening size of the movable jaws and the lower jaws as well as the clamping force, which improves the stability of the sampling clamps and the consistency of the machine, and effectively improves the accuracy and efficiency of the short fiber rate test data.

[0042] It will be apparent to those skilled in the art that the above specific examples are merely preferred embodiments of this utility model. Therefore, any improvements or modifications that those skilled in the art may make to certain parts of this utility model still embody the principles of this utility model and achieve its purpose, and all fall within the scope of protection of this utility model.
