Specific embodiments

[0028] Next, the present invention will 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, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1

[0030] As Figure 1 、 2 shown, the present invention provides an automatic cotton sample retention device, which can be integrally installed and fixed on one side of a large-capacity cotton performance tester. It includes: a cotton feeding hopper 6, above which a packaging material 1 is arranged, and between the packaging material 1 and the cotton feeding hopper 6, a guiding roller group 9 for flattening the packaging material 1 is arranged; outside the cotton feeding hopper 6, an outer hoop 2 for shaping the packaging material 1 is arranged, and a packaging material shaping space is formed between the outer surface of the cotton feeding hopper 6 and the inner surface of the outer hoop 2; at the outlet of the cotton feeding hopper 6, a hot melt mechanism for hot melting the packaging material 1 is installed, and a control mechanism is connected to the hot melt mechanism.

[0031] Exemplarily, in the present invention, the control mechanism may be an electric control box 7, but in actual operation, it may also be other control devices. The main control program set in the electric control box 7 controls the operation of the actuator, the operation of the hot melt mechanism and the spraying of the cotton sample barcode information. The electric control box 7 receives the cotton sample information collected by the large-capacity cotton fiber performance tester, and sprays the barcode information on the surface of the packaging material to realize the supplementary display of the barcode information outside the packaging material.

[0032] The outlet of the cotton feeding hopper 6 is provided with a packing material feeding roller mechanism 8. After the packing material 1 passes through the outer hoop 2, the two sides of the packing material 1 pass through the packing material feeding roller mechanism 8 and then enter the hot melt mechanism for hot melt sealing of the edges. Figure 3 As shown, the packaging material feeding roller mechanism includes: an active roller 81, a driven roller 82, a motor mounting plate 83, and a stepper motor 84; wherein the active roller 81 is meshed with the driven roller 82, the stepper motor 84 drives the active roller 81 to rotate, and the active roller 81 and the driven roller 82 rotate synchronously in opposite directions to drive the packaging material 1 to feed.

[0033] Specifically, the hot melt mechanism includes: a vertical hot melt block 3 arranged at one side of the outlet of the cotton feed hopper 6, and a transverse hot melt block 4 arranged below the cotton feed hopper 6. The transverse hot melt block 4 is provided with meshing teeth, and the transverse fusion surface is cut when closed. A cotton pressing block 5 for vertical extrusion is installed at the entrance of the cotton feed hopper 6, such as Figure 4 As shown, the cotton pressing block 5 is installed on the cotton feeding hopper 6 through the mounting frame 10. In addition, a transverse cotton pressing plate is installed at the end of the transverse hot melting block 4. The cotton pressing plate first contacts the packaging material 1 before the transverse hot melting block 4 is closed, which can realize the transverse compression of the cotton sample packaging material and reduce the sample volume.

[0034] In addition, the guide roller group 9 includes: an upper guide roller 91 and a lower guide roller 92. After the packaging material 1 passes through the guide roller group 9, it passes through the upper guide roller 91 and the lower guide roller 92 in an S shape and enters the outer hoop 2.

[0035] like Figure 5 , 6 As shown, the outer hoop 2 comprises: a clamp ring 21 for coaxially mounting on the outside of the cotton feed hopper 6, and a C-shaped funnel 22 is arranged on the clamp ring 21. The cotton feed hopper 6 is in the shape of a funnel, and the bottom is in the shape of an annular flanged opening.

[0036] Embodiment 2

[0037] The present invention also provides a cotton automatic sample retaining device and a sample retaining method, comprising:

[0038] 1. After the packaging material 1 passes through the guide roller group 9, it passes through the outer hoop 2 of the outer wall of the cotton inlet hopper 6, so that the packaging material 1 gradually changes from the initial straight shape to a C shape;

[0039] 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 electric control box 7 completes the closing of the vertical hot melt block 3, causing the vertical edges of the packaging material 1 to fuse. At the same time, the cylinder completes the closing action of the horizontal hot melt block 4. After fusing and cutting one end of the packaging material 1, the horizontal hot melt block 4 is opened.

[0040] 3. When the vertical hot melt reaches the preset length, the cylinder moves in the reverse direction to open the vertical hot melt block 3.

[0041] Embodiment 2

[0042] As Figure 7 shown, the specific sample retention method of the present invention based on the device of Embodiment 1 is as follows:

[0043] After the first use or replacement of the packaging material 1:

[0044] Before starting to use, the packaging material needs to be wound around the packaging material guiding roller group 9 along an S-shaped trajectory to increase the tension of the packaging material and ensure the smooth feeding of the packaging material.

[0045] Then, the end face of the packaging material 1 in a straight line passes through the slits of the outer hoop 2 and the cotton feeding hopper 6 to form a C-shaped cross-section. The side edges of the C-shaped packaging material pass through the two sets of leather roller wheels of the packaging material feeding roller 8 and cross over the bottom edge of the horizontal hot melt block 4 by about 1 cm, thus completing the initial position setting of the automatic sample retention packaging material.

[0046] First vertical packaging material fusion:

[0047] When the packaging material 1 passes through the slits of the outer hoop 2 and the cotton feeding hopper 6 and reaches the position of the vertical hot melt block 3, the packaging material is in a "C"-shaped open state. The main control program set in the electric control box 7 controls the cylinder to complete the closing action of the vertical hot melt block 3, realizing the fusion of the vertical edges of the packaging material, with a fusion length of 200 m. After the fusion duration is completed, the cylinder moves in the reverse direction, and the hot melt cleaning control program runs to complete the cleaning of the vertical hot melt block 3.

[0048] First packaging material feeding:

[0049] Subsequently, under the control of the packaging material feeding roller 8, the packaging material 1 is fed 100 mm by the rotation of a pair of leather rollers provided on the C-shaped end face of the packaging material 1. According to actual requirements, the feeding length can be flexibly set according to the motor rotation speed and the motor rotation duration.

[0050] Normal working cycle:

[0051] The main control program set in the electric control box 7 controls the cylinder to complete the closing action of the vertical hot melt block 3, realizing the fusion of the vertical edges of the packaging material. The fusion length this time is 200 m, and the total after combining with the first hot melt length is 300 mm;

[0052] Meanwhile, the main control program set in the electric control box 7 controls the cylinder to complete the closing action of the horizontal hot melt block 4, realizing the fusion of the horizontal edges of the packaging material, with a fusion length of 225 m. The structure of the horizontal hot melt block 4 is designed with meshing tooth shapes, and when closing, the horizontal fusion surface can be cut into two independent parts containing the horizontal fusion surface.

[0053] Preferably, a coding device is provided on the accessory part of the structure of the horizontal hot melt block 4. When the packaging material 1 is horizontally fused, the coding device sprays cotton sample barcode information on the surface of the packaging material 1. After the vertical hot melt block 3 and the horizontal hot melt block 4 of the packaging material 1 complete hot melting, after the sensor senses that the two groups of hot melt blocks are normally reset, it indicates to the operator that the cotton sample can be delivered.

[0054] After the operator completes the test of a single cotton sample, the cotton sample barcode information and test information are input into the host of the large-capacity cotton fiber performance tester. The operator completely puts the tested cotton sample and barcode into the cotton hopper 6. After the photoelectric switch set in the cotton hopper 6 senses that there is a cotton sample, the main control program set in the electric control box 7 controls the actuator to vertically transport the pressing cotton block 5 into the packaging material 1 that has been preformed into a "bag" shape, completing the vertical compression of the cotton sample to ensure that the cotton sample completely enters the packaging material 1. After the pressing cotton block completes the vertical compression of the cotton sample, the main control program set in the electric control box 7 controls the actuator to move the pressing cotton block 5 back to its original position. After the photoelectric induction switch senses that the pressing cotton block reaches the initial position, the main control program set in the electric control box 7 controls the packaging material feeding roller 8 to feed the packaging material 1 in this state by 200 mm. Under the control of the main control program set in the electric control box 7, the vertical hot melt block 3 and the horizontal hot melt block 4 complete closing, realizing the cutting of the packaging material already loaded with the cotton sample and the vertical and horizontal fusion of the packaging material not loaded with the cotton sample. Repeating this process, the continuous, automated, and information-based sampling of the cotton sample is realized.

[0055] For those skilled in the art, it is obvious that the above specific factual examples are only the preferred solutions of the present invention. Therefore, the improvements and changes that those skilled in the art may make to some parts of the present invention still embody the principle of the present invention and achieve the purpose of the present invention, and all belong to the scope protected by the present invention.
