Detailed Implementation

[0023] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] Example 1

[0025] like Figure 1 , 2 As shown, this utility model provides an automatic cotton sampling device, which can be installed and fixed as a whole on one side of a large-capacity cotton performance tester. It includes: a cotton inlet hopper 6, with a packaging material 1 disposed above the cotton inlet hopper 6; a guide roller assembly 9 for flattening the packaging material 1 is disposed between the packaging material 1 and the cotton inlet hopper 6; an outer hoop 2 for shaping the packaging material 1 is disposed on the outer side of the cotton inlet hopper 6, forming a packaging material shaping space between the outer surface of the cotton inlet hopper 6 and the inner surface of the outer hoop 2; and a heat-sealing mechanism for packaging the packaging material 1 is installed at the outlet of the cotton inlet hopper 6, with a control mechanism connected to the heat-sealing mechanism.

[0026] For example, in this utility model, the control mechanism can be an electrical control box 7, but in actual operation, it can also be other control devices. The main control program set in the electrical control box 7 controls the operation of the execution mechanism, controls the operation of the hot-melt mechanism, and controls the spraying of barcode information on the cotton sample. The electrical control box 7 receives cotton sample information collected by a high-capacity cotton fiber performance tester and sprays barcode information on the surface of the packaging material to achieve supplementary display of barcode information on the outside of the packaging material.

[0027] A packaging material feeding roller mechanism 8 is provided at the outlet of the cotton inlet hopper 6. After the packaging material 1 passes through the outer hoop 2, both sides of the packaging material 1 pass through the packaging material feeding roller mechanism 8 and then enter the hot-melt mechanism for edge hot-melt sealing. Figure 3 As shown, the packaging material feeding roller mechanism includes: a driving roller 81, a driven roller 82, a motor mounting plate 83, and a stepper motor 84; wherein, the driving roller 81 and the driven roller 82 mesh with each other, the stepper motor 84 drives the driving roller 81 to rotate, and the driving roller 81 and the driven roller 82 rotate synchronously in opposite directions, thereby feeding the packaging material 1.

[0028] Specifically, the heat-melting mechanism includes: a vertical heat-melting block 3 disposed on the outlet side of the cotton inlet hopper 6, and a horizontal heat-melting block 4 disposed below the cotton inlet hopper 6. The horizontal heat-melting block 4 is provided with meshing teeth, which cut the horizontal fusion surface when closed. A pressing block 5 for vertical compression is installed at the inlet of the cotton inlet hopper 6, such as... Figure 4 As shown, the cotton pressing block 5 is mounted on the cotton inlet hopper 6 via the mounting bracket 10. In addition, a transverse cotton pressing plate is installed at the end of the transverse hot-melt block 4. The cotton pressing plate contacts the packaging material 1 before the transverse hot-melt block 4 closes, which can realize the transverse compression of the packaging material containing the cotton sample and reduce the sample volume.

[0029] In addition, the guide rod assembly 9 includes an upper guide rod 91 and a lower guide rod 92. After the packaging material 1 passes through the guide rod assembly 9, it passes through the upper guide rod 91 and the lower guide rod 92 in an S-shape and enters the outer hoop 2.

[0030] like Figure 5 , 6 As shown, the outer hoop 2 includes a retaining ring 21 for coaxial installation on the outside of the cotton inlet hopper 6, and a C-shaped funnel 22 is provided on the retaining ring 21. The cotton inlet hopper 6 is funnel-shaped with an annular flanged opening at the bottom.

[0031] The working process of this utility model is as follows:

[0032] 1. After the packaging material 1 passes through the guide roller assembly 9, it passes through the outer hoop 2 on the outer wall of the cotton hopper 6, so that the packaging material 1 gradually changes from the initial straight shape to the final C shape;

[0033] 2. When the cotton sample enters the packaging material 1 and reaches the position of the vertical hot melt block 3, the control cylinder in the electrical control box 7 completes the closing of the vertical hot melt block 3, so that the vertical edge of the packaging material 1 is melted. At the same time, the cylinder completes the closing action of the horizontal hot melt block 4, after melting and cutting one end of the packaging material 1, the horizontal hot melt block 4 is opened.

[0034] 3. When the vertical heat melt reaches the preset length, the cylinder moves in the opposite direction to open the vertical heat melt block 3.

[0035] Specifically:

[0036] After first use or replacement of packaging material 1:

[0037] Before use, the packaging material should be routed around the packaging material guide roller assembly 9 along an S-shaped path to increase the packaging material tension and ensure smooth feeding of the packaging material.

[0038] Then, the straight end face of the packaging material 1 is passed through the slits of the outer hoop 2 and the cotton inlet hopper 6 to form a C-shaped cross section. After the side of the C-shaped packaging material passes through the two sets of leather rollers of the packaging material feed roller 8, it passes about 1 cm past the bottom edge of the transverse hot melt block 4, thus completing the initial position setting of the automatic sample packaging material.

[0039] First vertical packaging material fusion:

[0040] After passing through the narrow gaps of the outer hoop 2 and the cotton inlet hopper 6, the packaging material 1 reaches the position of the vertical heat-melting block 3 with a "C"-shaped opening. The main control program in the electrical control box 7 controls the cylinder to complete the closing action of the vertical heat-melting block 3, achieving vertical edge fusion of the packaging material with a fusion length of 200m. After the fusion time is maintained, the cylinder moves in the reverse direction, and the heat-melting cleaning control program runs to complete the cleaning of the vertical heat-melting block 3.

[0041] Initial packaging material feed:

[0042] Subsequently, under the control of the packaging material feed roller 8, the packaging material 1 is fed 100mm by a pair of rollers set on the C-shaped end face of the packaging material 1. The feed length can be flexibly set according to actual needs based on the motor rotation speed and motor rotation time.

[0043] Normal working cycle:

[0044] The main control program set in the electrical control box 7 controls the cylinder to complete the closing action of the vertical hot melt block 3, realizing the vertical edge fusion of the packaging material. The fusion length is 200m, and the total length after combining the first hot melt length is 300mm.

[0045] Meanwhile, the main control program set in the electrical control box 7 controls the cylinder to complete the closing action of the transverse hot melt block 4, realizing the fusion of the transverse edge of the packaging material, with a fusion length of 225m; the transverse hot melt block 4 is designed with meshing teeth, which can cut the transverse fusion surface into two independent parts containing the transverse fusion surface when closing.

[0046] Preferably, the auxiliary part of the transverse hot melt block 4 is equipped with a coding device. When the packaging material 1 is fused laterally, the coding device sprays the cotton sample barcode information onto the surface of the packaging material 1. After the vertical hot melt block 3 and the transverse hot melt block 4 of the packaging material 1 have completed the hot melt process, the sensor detects that the two sets of hot melt blocks have been reset normally and instructs the operator to deliver the cotton sample.

[0047] After completing a single cotton sample test, the operator inputs the cotton sample barcode information and test information into the main unit of the high-capacity cotton fiber performance tester. The operator then carefully inserts the tested cotton sample and barcode into the cotton hopper 6. Upon sensing the presence of a cotton sample, a photoelectric switch located in the cotton hopper 6 activates the main control program in the control box 7, which controls the actuator to vertically transport the cotton pressing block 5 into the pre-formed "bag"-shaped packaging material 1, completing the vertical compression of the cotton sample and ensuring its complete entry into the packaging material 1. After the cotton pressing block completes the vertical compression, the main control program in the control box 7 moves the cotton pressing block 5 back to its original position. Once the photoelectric sensor detects that the cotton pressing block has reached its initial position, the main control program in the control box 7 controls the packaging material feed roller 8 to feed the packaging material 1 200mm. Under the control of the main control program set in the electrical control box 7, the vertical hot melt block 3 and the horizontal hot melt block 4 are closed, realizing the cutting of the cotton sample packaging material and the vertical and horizontal fusion of the non-cotton sample packaging material. This process is repeated to achieve continuous, automated, and information-based sample retention of cotton samples.

[0048] 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.
