Technical Field

[0001] The present invention relates to the technical field of knitted fabric detection, and particularly relates to a detection device for a cut-resistant and soft knitted fabric with strength and toughness. Background Art

[0002] The cut-resistant and soft knitted fabric is a special textile, and its main feature is that it can resist the cutting action of sharp objects such as blades to a certain extent while maintaining good softness and comfort.

[0003] Currently, after the production of the cut-resistant and soft knitted fabric, generally, the cut-resistant strength of the cut-resistant and soft knitted fabric is detected. However, the existing detection devices have complex structures and large volumes, cannot be carried and moved portably, cannot detect any area of the cut-resistant and soft knitted fabric, and the detection process is generally carried out outdoors, which easily causes the debris during the cutting process to fall in the working area, increasing the subsequent workload. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a detection device for a cut-resistant and soft knitted fabric with strength and toughness, which is portable and can perform cutting detection on any position of the fabric to be detected by carrying, and avoids the exposure of debris by pulling inward, so as to solve the problems mentioned in the above background art.

[0005] The present invention is realized through the following technical solutions: A detection device for a cut-resistant and soft knitted fabric with strength and toughness, including a cylinder body, a fabric to be detected, and a cutting sleeve. The cutting sleeve is arranged inside the cylinder body. A detection channel for the fabric to be detected to enter is formed at the center of the cutting sleeve. A plurality of cutting parts distributed in an annular structure are installed on the inner wall surface of the detection channel. A crochet hook opposite to the detection channel is also arranged inside the cylinder body. The fabric to be detected is pulled into the detection channel by the crochet hook and is in contact with the cutting parts. An electric push rod for driving the crochet hook to lift and a driving mechanism for driving the cutting sleeve to rotate are installed on the bottom surface of the cylinder body.

[0006] As a preferred technical solution, the crochet hook includes a needle body, a hook block, a top rod, and a compression rod. A positioning groove is arranged on one side of the needle body, and a positioning port communicating with the positioning groove is axially arranged inside the needle body. One end of the hook block is inserted into the positioning groove and is installed with a first compression spring. The other end of the first compression spring is installed on the inner wall surface of the positioning groove. The other end of the hook block is exposed and is inclined to form a first diversion part. A diversion groove is arranged at the end of the hook block located inside the positioning groove. The top rod is arranged inside the positioning port. The end of the top rod facing the diversion groove forms a second diversion part. The other end of the top rod is installed with a second compression spring. The other end of the second compression spring is installed on the inner wall surface of the positioning port. A rectangular port communicating with the outside is arranged at the end of the positioning port far from the positioning groove. One end of the compression rod passes through the rectangular port and is installed on the top rod;

[0007] The crochet hook further includes a push plate. One end of the push plate is arranged close to the pressure rod, and the other end is bent and installed on the cylinder body; the top of the needle body passes through the fabric to be detected, and one side of the hook block is in contact with the fabric to be detected.

[0008] As a preferred technical solution, the detection channel is arranged in a conical structure, gradually narrowing from top to bottom. The outer wall surface of the cutting sleeve forms a shock-absorbing groove in an annular structure, and the diameter of the cutting sleeve matches the inner diameter of the cylinder body.

[0009] As a preferred technical solution, the driving mechanism includes a motor, a gear, a driving sleeve and multiple convex teeth. The driving sleeve is installed on the cutting sleeve, and multiple convex teeth are installed in the opening at one end of the driving sleeve in an annular structure. The motor is installed on the outer wall surface of the cylinder body. The rotating shaft of the motor passes through the through hole and is fixedly connected to the gear, and the gear is meshed with the convex teeth.

[0010] As a preferred technical solution, a retreat space for the hook block to retract into the positioning groove is formed between the positioning groove and the hook block, and the first compression spring is arranged in the retreat space.

[0011] As a preferred technical solution, both the cylinder body and the cutting sleeve are made of transparent plastic materials.

[0012] As a preferred technical solution, the cross sections of the positioning opening and the positioning rod are arranged in a rectangular structure.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. It is small in size and convenient to carry. After the crochet hook extends out, it can be inserted into any part of the fabric to be detected, and by retracting, this part of the fabric to be detected can be pulled into the detection channel and contacted with the cutting part, and the fabric to be detected entering can be tightened by pulling to ensure detection.

[0015] 2. The driving mechanism can drive the rotation of the driving sleeve and the cutting sleeve, and the rotation of the cutting sleeve drives the cutting part, and the fabric to be detected pulled in can be comprehensively cut by the rotating cutting part.

[0016] 3. Since the fabric to be detected is pulled into the detection channel, the debris generated during the cutting process will be collected by the cylinder body, avoiding exposure.

[0017] 4. As the crochet hook further descends, the hook block on the crochet hook can retract into the positioning groove. After losing the block of the hook block, the fabric to be detected can be directly pulled outwards, facilitating the pulling and taking of the material and increasing the convenience of operation.

That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0030] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, a detection device for a cut-resistant soft knitted fabric with strength and toughness according to the present invention includes a cylinder body 1, a fabric to be detected 2, and a cutting sleeve 7. The cutting sleeve 7 is arranged inside the cylinder body 1. A detection channel for the fabric to be detected to enter is formed at the center of the cutting sleeve 7. A plurality of cutting parts 8 distributed in an annular structure are installed on the inner wall surface of the detection channel. A crochet hook opposite to the detection channel is also arranged inside the cylinder body 1. The fabric to be detected is pulled into the detection channel by the crochet hook and is in contact with the cutting parts 8. An electric push rod 3 for driving the crochet hook to lift and a driving mechanism for driving the cutting sleeve 7 to rotate are installed on the bottom surface of the cylinder body 1. Among them, a storage battery for supplying power to the driving mechanism and the electric push rod is installed in the area with an empty interior of the cylinder body, and a controller for controlling the driving mechanism and the electric push rod is installed outside the cylinder body.

[0031] In this embodiment, the crochet hook includes a needle body 5, a hook block 6, a top rod 15, and a pressure-receiving rod 14. A positioning groove is arranged on one side of the needle body 5. A positioning port communicating with the positioning groove is axially arranged inside the needle body 5. One end of the hook block 6 is inserted into the positioning groove, and a first compression spring 19 is installed. The other end of the first compression spring 19 is installed on the inner wall surface of the positioning groove. The other end of the hook block 6 is exposed and inclined to form a first diversion part. A diversion groove 18 is arranged at one end of the hook block 6 located inside the positioning groove. The top rod 15 is arranged inside the positioning port. A second diversion part 16 is formed at one end of the top rod 15 facing the diversion groove 18. A second compression spring 17 is installed at the other end of the top rod 15. The other end of the second compression spring 17 is installed on the inner wall surface of the positioning port. A rectangular port communicating with the outside is arranged at one end of the positioning port far from the positioning groove. One end of the pressure-receiving rod 14 passes through the rectangular port and is installed on the top rod 15.

[0032] The crochet hook further includes a push plate 13. One end of the push plate 13 is close to the pressure-receiving rod 14, and the other end is bent and installed on the cylinder body 1. The top of the needle body 5 passes through the fabric to be detected 2. One side surface of the hook block 6 is in contact with the fabric to be detected 2.

[0033] In this embodiment, the detection channel is arranged in a conical structure and gradually narrows from top to bottom. An annular shock-absorbing groove 9 is formed on the outer wall surface of the cutting sleeve 7. The diameter of the cutting sleeve 7 matches the inner diameter of the cylinder body 1.

[0034] In this embodiment, the driving mechanism includes a motor 4, a gear 12, a driving sleeve 10 and a plurality of convex teeth 11. The driving sleeve 10 is mounted on the cutting sleeve 7. The plurality of convex teeth 11 are mounted in an annular structure in an opening at one end of the driving sleeve 10. The motor 4 is mounted on the outer wall surface of the cylinder 1. The rotating shaft of the motor 4 passes through the through hole and is fixedly connected to the gear 12. The gear 12 is meshed and connected with the convex teeth 11.

[0035] The motor is a reduction motor, which reduces the rotation resistance of the cutting sleeve. After the panel to be detected is pulled into the detection channel, the part of the panel to be detected located outside will cover the open end surface of the cylinder, thereby blocking the cutting sleeve and preventing it from falling out.

[0036] On the contrary, after the panel to be tested is removed from the cylinder, the cutting sleeve can also be directly disassembled outward, which greatly facilitates replacement. By replacing different cutting sleeves to replace the internal cutting part, different cutting sleeves have cutting parts with different sharpness, so that panels to be tested with different strengths can be tested.

[0037] In this embodiment, a retreat space is formed between the positioning groove and the hook block 6 for the hook block 6 to retract into the positioning groove. The first compression spring 19 is disposed in the retreat space so that the hook block can be smoothly retracted into the needle body.

[0038] In this embodiment, the cylinder 1 and the cutting sleeve 7 are both made of transparent plastic material, so that the internal cutting conditions and whether the fabric to be tested is in contact with the cutting part can be clearly seen through the cylinder and the cutting sleeve.

[0039] In this embodiment, the cross-sections of the positioning opening and the positioning rod are arranged in a rectangular structure, so that the top rod can only be raised and lowered along the positioning opening, thereby avoiding misalignment caused by rotation.

[0040] When in use, the electric push rod is started, and the extension of the piston rod on the electric push rod can drive the hook needle to extend to the outside along the detection channel. At this time, the hook needle can pass through any part of the fabric to be detected. During the insertion of the hook needle, the fabric to be detected can squeeze the hook block through its own toughness, so that the hook block automatically retracts into the inside of the positioning groove. After the top of the needle body passes through the fabric to be detected, the rebound of the first compression spring can pop out the hook block, so that one side of the hook block contacts the outer surface of the fabric to be detected.

[0041] After the above is completed, the piston rod of the electric push rod can be retracted, and the surface to be tested can be hooked by the hook block and pulled into the detection channel until it contacts the cutting part on the cutting sleeve. At this time, the motor can be started, and the start of the motor drives the gear, which drives the rotation of the driving sleeve and the cutting sleeve by turning the convex teeth. The rotation of the cutting sleeve synchronously drives the cutting part, and the cutting strength of the pulled-in fabric to be tested can be tested through the cutting part. The shape of the detection channel is formed by the composite of the fabric to be tested after being pulled in, so that the cutting part can contact the fabric to be tested at multiple points, thereby increasing the comprehensiveness of the detection.

[0042] During the cutting strength test, the generated debris will be collected by the cylinder to avoid leakage.

[0043] Among them, after the cutting is completed, the piston rod can be further retracted, and the movement of the piston rod drives the needle body until the pressure rod contacts the push plate. The push plate can squeeze the pressure rod to make the pressure rod move upward along the rectangular opening. The movement of the pressure rod synchronously drives the push rod until the second guide part on the push rod is inserted into the guide groove. The squeezing between the two can drive the hook block into the positioning groove. After the obstruction of the hook block is lost, the fabric to be detected can be directly pulled out of the detection channel by the worker, which is convenient for taking out the panel to be detected and checking it.

[0044] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
