Description

Technical Field

[0001] The invention relates to the technical field related to material detection and testing, and in particular to a printing and dyeing fabric detection sampling device. Background Art

[0002] Printed and dyed fabrics refer to fabrics that are printed with various patterns and colors through printing and dyeing processes to increase their beauty and value. Printed and dyed fabrics can be used in various clothing, home textiles, shoes and hats, and other fields, and are a very important part of the modern textile industry; there are many printing processes for printed and dyed fabrics, including screen printing, lithography, flexographic printing, inkjet printing, etc., and there are also many dyeing processes for printed and dyed fabrics, including dyeing, pigment dyeing, chemical dyeing, etc. In the existing market, after the fabric is printed and dyed, it is generally necessary to conduct physical and chemical testing on the fabric sections to test the air permeability, comfort and composition of the fabric. The physical testing methods can be divided into density method, melting point method, etc., and the chemical testing methods are combustion method and dissolution method, etc. When testing the fabric, it is necessary to sample the fabric. By sampling different positions on the fabric and then using external testing devices, the effect of fabric testing can be achieved.

[0003] The fabric sampling device on the existing market is generally only set as a platform when sampling fabrics. A circular knife that can move up and down is set on the top of the platform. The circular knife can move downward to contact the fabric on the platform to achieve the effect of cutting and sampling the fabric. However, the general fabric detection work is all inside the fabric processing plant. When the fabric is processed, the fabric is printed and dyed in batches. Therefore, when sampling the fabric, the sampling work is generally carried out directly on the batch-produced fabric. When sampling the fabric through the traditional sampling device, first of all, the cut fabric is light in weight. Therefore, after the cutting is completed, in order to avoid the phenomenon of fabric flying away on the conveyor belt, it is often necessary for the staff to manually or mechanically take the fabrics one by one. The operation is too troublesome, which not only makes the sampling efficiency low, but also affects the efficiency of the entire fabric production and processing. At the same time, when the fabric is taken mechanically or manually, the fabric cannot be sorted and stacked, resulting in a large amount of fabric piled up, which requires subsequent manual sorting. Summary of the invention

[0004] The object of the present invention is to provide a printing and dyeing fabric detection sampling device to solve the problem that the sampling devices currently on the market proposed in the above background technology, when sampling fabrics, first of all, since the cut fabrics are light in weight, in order to avoid the phenomenon of fabrics flying away on the conveyor belt after cutting, it is often necessary for staff to manually or mechanically take them one by one, and the operation is too troublesome, which not only makes the sampling efficiency low, but also affects the efficiency of the entire fabric production and processing.

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] See also Figure 1-8 , the present invention provides a technical solution: a printing and dyeing fabric detection sampling device, comprising a work surface 1, which includes a work table at the top and a support seat at the bottom;

[0057] The support frame 2 is a "U"-shaped structure fixed on the top of the workbench 1 and is used for installing the sampling device;

[0058] A lifting mechanism 3 is provided at the bottom of the support frame 2;

[0059] Also includes;

[0060] The sampling and collecting mechanism 4 is arranged in the middle of the lifting mechanism 3 and is driven by the lifting mechanism 3 to move up and down;

[0061] The corresponding pushing mechanism 5 is arranged at the top center of the work surface 1, and its position corresponds to the position of the sampling and collecting mechanism 4;

[0062] The sampling and collecting mechanism 4 includes a sampling mechanism and a collecting mechanism. The collecting mechanism is arranged above the sampling mechanism. The fabric sampled by the sampling mechanism will be squeezed by the corresponding pushing mechanism 5 into the interior of the collecting mechanism for collection.

[0063] The present application provides a printing and dyeing fabric detection sampling device with a sampling and collecting mechanism 4. Specifically, when it is used, the entire device is first fixed in a suitable position under the action of a support seat at the bottom of the support table 1. Then, the fabric to be sampled is placed on the workbench on the support table 1, and the lifting mechanism 3 is started, so that it drives the sampling and collecting mechanism 4 in the middle to move downward and engage with the corresponding pushing mechanism 5. Thus, the sampling mechanism completes the effect of cutting and sampling the fabric covered on the corresponding pushing mechanism 5, and the sampled fabric will be directly collected inside the collecting mechanism. The lifting mechanism 3 is controlled to move upward again to transfer the fabric, and sampling work can be performed on another position on the fabric.

[0064] Finally, the fabric only needs to be taken out from the collection mechanism for subsequent testing.

[0065] Among them, according to Figure 1 As shown, both side walls of the support frame 2 are penetrated with holes for the transmission and penetration of the cloth, and a reserved hole is also provided at the middle position of the top of the support frame 2 for the up and down movement of the sampling and collecting mechanism 4;

[0066] Specifically, when the fabric is being transmitted, the top end of the fabric can be passed through the perforation on the side wall of the support frame 2. After that, the continuous transmission of the fabric on the conveying roller is controlled to complete the continuous sampling work on the fabric.

[0067] As a further preference of this embodiment, according to Figure 2 As shown, the lifting mechanism 3 includes:

[0068] Telescopic cylinders 31, two of which are symmetrically arranged on both sides of the top of the support frame 2;

[0069] A lifting plate 32 is fixedly installed at the bottom of the two telescopic cylinders 31;

[0070] A threaded hole 321 is provided through the middle of the lifting plate 32, and the threaded hole 321 is threadedly connected to the sampling and collecting mechanism 4;

[0071] Specifically, when controlling the sampling and collecting mechanism 4 to move up and down, it is only necessary to control the telescopic cylinder 31 to start, so that it drives the lifting plate 32 at the bottom to move up and down. Therefore, when the lifting plate 32 moves up and down, it can drive the sampling and collecting mechanism 4 in the middle to move up and down, and complete the work of cutting and sampling the fabric;

[0072] In the present application, since the sampling and collecting mechanism 4 is threadedly connected to the lifting plate 32, when the sampling area of ​​the fabric needs to be adjusted, it is only necessary to threadably install a sampling and collecting mechanism 4 of another size, which provides better flexibility.

[0073] Further, according to Figure 2-3 As shown, the sampling mechanism and the collecting mechanism are both cylindrical structures, and the two penetrate each other, and the sampling mechanism is arranged at a position slightly below the middle of the lifting mechanism 3, and the collecting mechanism is arranged at a position slightly above the middle of the lifting mechanism 3;

[0074] Specifically, the sampling mechanism is arranged at the bottom of the collecting mechanism. When the sampling mechanism descends to cut and sample the fabric, since the sampling mechanism and the collecting mechanism penetrate each other, the collecting mechanism can directly collect the fabric after cutting and sampling.

[0075] As a further preference of this embodiment, according to Figure 2-3 As shown, the sampling mechanism includes a sampling ring knife 41, which specifically includes a sampling tube 411 and a ring blade 412. The sampling tube 411 is a hollow cylindrical structure that penetrates from top to bottom, and a thread is provided at the top thereof to connect with the lifting mechanism 3;

[0076] A ring blade 412 is fixedly installed at the bottom of the sampling tube 411;

[0077] Specifically, when the sampling mechanism descends, the ring blade 412 at the bottom of the sampling ring knife 41 will come into contact with the fabric, so that the fabric at the bottom can be sampled by ring cutting.

[0078] As a further preference of this embodiment, according to Figure 2-3 and Figure 5-6 As shown, the collecting agencies include;

[0079] The collecting barrel 42 is also in the form of a hollow cylindrical structure penetrating from top to bottom, and a thread is arranged on the outer side of the bottom thereof to connect with the lifting mechanism 3;

[0080] A blocking cover 43 is disposed at the top of the collecting barrel 42, and a squeezing mechanism 44 is installed on the bottom plate of the blocking cover 43;

[0081] A shielding mechanism 45 is disposed at a lower position inside the collecting barrel 42 and is used to shield and store the sampled fabric inside the collecting barrel 42;

[0082] Specifically, when the sampling mechanism descends and completes cutting of the fabric, the sampling mechanism is controlled to continue to move downward, and it will contact with the corresponding pushing mechanism 5, so that the corresponding pushing mechanism 5 squeezes the cut fabric into the interior of the collecting barrel 42, and the fabric entering the interior of the collecting barrel 42 is blocked by the blocking mechanism 45, so it will be separated from the corresponding pushing mechanism 5, thereby making the fabric stay in the collecting barrel 42, and as the corresponding pushing mechanism 5 separates from the collecting mechanism, its top end will not squeeze the squeezing mechanism 44, thereby making the squeezing mechanism 44 descend, and squeeze and flatten the fabric inside the collecting barrel 42, so as to achieve the effect of sorting it and reducing the space it occupies.

[0083] Furthermore, according to Figure 5-6 As shown, the extrusion mechanism 44 includes;

[0084] The mounting cylinder 441 is provided in a cylindrical structure, and the top end thereof is integrally mounted with the blocking cover 43;

[0085] The extrusion springs 442 are distributed at equal angles at the bottom of the mounting tube 441, and the bottom of the extrusion springs 442 is also connected to an extrusion column 443;

[0086] The outer side of the mounting tube 441 is provided with threads and is threadedly connected to the inner top of the collecting barrel 42, and the original length of the squeezing spring 442 is greater than half the length of the collecting barrel 42;

[0087] Specifically, when the corresponding pushing mechanism 5 enters the interior of the collecting mechanism, its top end will squeeze the bottom of the squeezing column 443, so that the squeezing column 443 squeezes the squeezing spring 442 to compress, thereby ensuring that the fabric can enter the interior of the collecting mechanism, and when the corresponding pushing mechanism 5 is separated from the collecting mechanism, the squeezing spring 442 will automatically reset at this time, so that the squeezing column 443 descends, and the fabric is squeezed and sorted;

[0088] Finally, it is only necessary to rotate the blocking cover 43 so that it drives the installation cylinder 441 and the collection barrel 42 to be disassembled, and then separate the extrusion spring 442 and the extrusion column 443 from the collection barrel 42, and then the fabric inside can be taken out and collected.

[0089] Furthermore, according to Figure 6-8 As shown, the shielding mechanism 45 is provided with 4 groups at equal angles below the inner wall of the collecting barrel 42, and specifically includes:

[0090] The fixing seat 451 is arranged in a rectangular structure and is fixed to the inner wall of the collecting barrel 42;

[0091] The mounting shaft 452 is annularly fixed between the two fixing seats 451;

[0092] The rotating cylinder 453 is sleeved on the outside of the mounting shaft 452 and forms a rotating mechanism with the mounting shaft 452;

[0093] The rotating plate 454 is integrally installed with the outer side of the rotating cylinder 453 and has a fan-shaped structure when viewed from above. A shielding plate 455 with an inclined cross section is also provided at the top of the rotating plate 454;

[0094] The top ends of the shielding plates 455 on the four shielding mechanisms 45 are in contact with each other, and the four shielding plates 455 form a conical structure.

[0095] Limit blocks are provided on the outer side of the mounting shaft 452 and the inner side of the rotating cylinder 453 for controlling the rotating cylinder 453 to drive the rotating plate 454 to rotate from a horizontal position to a vertical position, and then from a vertical position to a horizontal position, to ensure that the rotating plate 454 cannot rotate downward.

[0096] Specifically, when the corresponding pushing mechanism 5 reaches the interior of the collecting mechanism, its top end will engage with the middle of the four shielding plates 455, so that the four shielding plates 455 drive the rotating plate 454 to rotate and open under the action of the rotating cylinder 453. Therefore, when the entire corresponding pushing mechanism 5 pushes the entire fabric into the interior of the collecting mechanism, the collecting mechanism can be controlled to rise. When rising, the corresponding pushing mechanism 5 and the shielding mechanism 45 are separated from each other. At this time, the rotating plate 454 is automatically reset under the squeezing action of gravity and the squeezing mechanism 44. After the middle position of the cut fabric is lifted by the pushing mechanism 5 and enters above the four rotating plates 454 and the shielding plates 455, the bottom will be in an open state. Therefore, the cut fabric will be blocked by the shielding plates 455 and the rotating plates 454 on the shielding mechanism 45 and cannot fall, thereby achieving the effect of collecting it.

[0097] In this application, according to Figure 1 and Figure 4 As shown, the corresponding driving mechanism 5 includes;

[0098] The reserved groove 51 is a cylindrical structure opened on the surface of the work surface 1, and its height is greater than the height of the collecting mechanism;

[0099] A support column 52 is fixed at the middle of the bottom of the reserved groove 51 and is used to fix the positioning cylinder 53 at the top thereof. The positioning cylinder 53 is an open cylindrical structure and is engaged with the collecting mechanism.

[0100] A top rod 54 is provided in a conical structure and is fixed at the center of the positioning tube 53. The size of the top rod 54 is greater than half of the height of the collecting mechanism;

[0101] Specifically, when the sampling mechanism continues to move downward, the positioning cylinder 53 and the push rod 54 on the entire corresponding pushing mechanism 5 will drive the cut fabric to enter the interior of the collecting mechanism through the interior of the sampling mechanism, thereby squeezing the shielding mechanism 45 and the squeezing mechanism 44 inside the collecting mechanism in turn, and finally the fabric is shielded by the shielding mechanism 45 and stays inside the collecting mechanism to implement the collection work. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0102] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
