Description

Technical Field

[0001] This utility model belongs to the field of silk detection technology, and in particular relates to a device for detecting the cohesion of raw silk. Background Technology

[0002] The silk cohesion test primarily assesses the performance of raw silk under friction and bending tension, particularly the ease with which individual filaments break apart under friction. This is an important indicator of raw silk quality, reflecting its durability and stability in practical use.

[0003] In Chinese utility model patent with announcement number CN219455899U, a raw silk cohesion detection device is disclosed, which greatly reduces the friction between the base and the mounting rod, can reduce the energy loss of the cylinder, improve efficiency, and make the device more energy-efficient. At the same time, it can reduce the wear at the sliding connection between the base and the mounting rod, improve its service life, and enable the overall mechanism of the tool holder to operate stably for a long time.

[0004] Research revealed that in the aforementioned devices, after the testing process is completed, multiple worm gears need to be manually rotated sequentially to reset multiple silk hooks for subsequent use. However, controlling multiple worm gears individually results in slow adjustment and low efficiency, while also increasing the operational burden and difficulty. Therefore, there is an urgent need to improve the existing raw silk cohesion detection device and provide a new raw silk cohesion detection device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a reasonably designed, simple, easy-to-reset, and easy-to-count raw silk cohesion detection device, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for detecting the cohesion of raw silk fibers includes a frame, a tool holder, and an infrared counting sensor. The frame has a mounting groove in its middle, a drive assembly is mounted in the middle of the inner side of the mounting groove, and the infrared counting sensor is fixedly mounted in the middle of the inner bottom surface of the mounting groove. Crossbars are symmetrically fixed to the inner upper side of the frame, and a fixing block is fixedly fitted onto the outer left end of each crossbar. A mounting plate is fixed to the upper end of the fixing block. Multiple grooves are equidistantly spaced along the length of the top right side of the mounting plate, and each groove contains a tightening assembly. The mounting plate has a groove at its bottom, and a movable rod slides within the groove. An electric push rod is fixedly installed at the center of the bottom of the mounting plate. The telescopic end of the electric push rod is fixedly connected to the movable rod. Multiple limiting blocks are slidably engaged inside the top of the movable rod. These limiting blocks correspond one-to-one with multiple sets of tightening components. A spring is fixedly connected between the limiting blocks and the movable rod. A fixed seat is fixedly fitted on the outer side of the right end of the crossbar. A base is slidably fitted on the outer side of the middle part of the crossbar. The upper end of the base is fixedly installed with the tool holder assembly.

[0008] In a preferred embodiment, the tightening assembly includes a fixed shaft, a coil spring, a take-up wheel, and a toothed disc. The two ends of the fixed shaft are respectively fixed to the inner walls of the front and rear sides of the groove. The take-up wheel is installed on the outer side of the middle part of the fixed shaft through the coil spring. The take-up wheel rotates within the groove. The toothed disc is fixedly sleeved on the outer sides of both the front and rear ends of the take-up wheel.

[0009] In a preferred embodiment, the top of the limiting block engages with the meshing structure of the toothed disc, and the right side of the top of the limiting block is inclined.

[0010] In a preferred embodiment, a plurality of wire hooks are fixed at equal intervals along the length of the outer wall on the left side of the top of the fixing base. The plurality of wire hooks are respectively arranged in a one-to-one correspondence with the plurality of tightening components, and the corresponding wire hooks and tightening components are on the same horizontal straight line.

[0011] In a preferred embodiment, a vertical rod is fixedly installed at the bottom center of the base, and the vertical rod has a through groove structure inside.

[0012] In a preferred embodiment, the drive assembly includes a drive motor, a disc, and a fixing post. The drive motor is fixedly installed on the rear inner wall of the mounting groove, and the output end of the drive motor is fixedly connected to the disc. The fixing post is fixedly installed on the outer edge of the front end face of the disc away from its center.

[0013] In a preferred embodiment, the front end of the fixed column is guided and slidably located in the internal through groove structure of the vertical rod, and the vertical rod and the base form a left-right reciprocating sliding structure through the fixed column.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the solution of this utility model:

[0016] This device allows for manual control of the rotation of each take-up wheel and toothed disc, facilitating the winding of excess raw silk onto the outside of the take-up wheel to achieve the purpose of tightening the raw silk and facilitating cohesion testing. Furthermore, the use of limit blocks to engage with the toothed discs allows for unidirectional rotation of the toothed discs and take-up wheels. After the test is completed, the movable rod can be controlled by an electric push rod to move vertically downward along the slide groove, which can simultaneously disengage multiple limit blocks from multiple toothed discs. At this time, under the action of the coil spring, multiple take-up wheels can be synchronously rotated and reset, eliminating the need for manual adjustment one by one, making operation more convenient and simpler, and adjustment more efficient.

[0017] The drive motor is started to control the disc to drive the fixed column to rotate synchronously and uniformly. At this time, the fixed column can squeeze the vertical rod with the through groove structure inside. This allows the vertical rod to drive the base and the knife holder to move back and forth synchronously along the horizontal bar, which is convenient for detecting the cohesion of the raw silk. Moreover, during the reciprocating movement of the vertical rod, it can pass directly above the infrared counting sensor, which makes it convenient to accurately count the number of frictions and obtain accurate detection results.

[0026] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0027] like Figure 1-5 As shown, this utility model of a raw silk cohesion detection device includes a frame 1, a knife holder assembly 17, and an infrared counting sensor 19. A mounting groove 2 is formed in the middle of the frame 1. A drive assembly 8 is installed in the middle of the inner side of the mounting groove 2. The infrared counting sensor 19 is fixedly installed in the middle of the inner bottom surface of the mounting groove 2. Crossbars 3 are symmetrically fixed to the inner side of the upper end of the frame 1. A fixing block 4 is fixedly sleeved on the outer side of the left end of the crossbar 3. A mounting plate 5 is fixed to the upper end of the fixing block 4. Multiple grooves 6 are equidistantly formed along the length of the top right side of the mounting plate 5. Each groove 6 contains a tightening assembly 7. A groove 9 is provided inside the bottom end of the plate 5, and a movable rod 11 is slidably arranged in the groove 9. An electric push rod 10 is fixedly installed in the middle of the bottom end of the mounting plate 5. The telescopic end of the electric push rod 10 is fixedly connected to the movable rod 11. Multiple limit blocks 13 are slidably engaged inside the top end of the movable rod 11. The multiple limit blocks 13 correspond one-to-one with multiple sets of tightening components 7. A spring 12 is fixedly connected between the limit blocks 13 and the movable rod 11. A fixed seat 14 is fixedly sleeved on the outer side of the right end of the crossbar 3. A base 16 is slidably sleeved on the outer side of the middle part of the crossbar 3. The upper end of the base 16 is fixedly installed with the tool holder integral mechanism 17.

[0028] Based on the above structure, the tightening assembly 7 includes a fixed shaft 71, a coil spring 72, a take-up wheel 73, and a toothed disc 74. The two ends of the fixed shaft 71 are respectively fixed to the inner walls of the front and rear sides of the groove 6. The take-up wheel 73 is installed on the outer side of the middle part of the fixed shaft 71 through the coil spring 72. The take-up wheel 73 rotates within the groove 6. The toothed disc 74 is fixedly sleeved on the outer sides of both the front and rear ends of the take-up wheel 73.

[0029] Based on the above structure, the top of the limiting block 13 engages with the meshing structure of the toothed disc 74, and the right side of the top of the limiting block 13 is inclined.

[0030] In this embodiment, the engagement between the top of the limiting block 13 and the meshing structure of the toothed disc 74 facilitates the stable unidirectional rotation of the toothed disc 74 and the winding wheel 73, making it easier to wind up excess raw silk and tighten the raw silk.

[0031] Based on the above structure, a number of wire hooks 15 are fixed at equal intervals along the length direction on the outer wall of the left side of the top of the fixing base 14. The multiple wire hooks 15 are respectively set in one-to-one correspondence with multiple sets of tightening components 7, and the corresponding wire hooks 15 and tightening components 7 are on the same horizontal straight line.

[0032] In this embodiment, multiple wire hooks 15 are used to facilitate the tightening and positioning of the other end of the raw silk, making it convenient for cohesion detection.

[0033] Based on the above structure, a vertical rod 18 is fixedly installed at the bottom center of the base 16, and the vertical rod 18 has a through groove structure inside.

[0034] Based on the above structure, the drive assembly 8 includes a drive motor 81, a disc 82 and a fixing post 83. The drive motor 81 is fixedly installed on the rear inner wall of the mounting groove 2. The output end of the drive motor 81 is fixedly connected to the disc 82. The fixing post 83 is fixedly installed on the outer edge of the front end face of the disc 82 away from its center.

[0035] Based on the above structure, the front end guide slide of the fixed column 83 is located in the internal through groove structure of the vertical rod 18, and the vertical rod 18 and the base 16 form a left-right reciprocating sliding structure through the fixed column 83.

[0036] In this embodiment, when the drive motor 81 is started to control the rotation of the disc 82 and the fixed column 83, the fixed column 83 can squeeze and push the vertical rod 18, the base 16 and the knife holder overall mechanism 17 to move back and forth synchronously along the horizontal bar 3, which facilitates the start of the cohesion detection of raw silk.

[0037] The working principle of this utility model is as follows:

[0038] In use, first fix both ends of the raw silk to the hanging hook 15 and the take-up reel 73 respectively. Then, manually rotate the toothed disc 74 and the take-up reel 73 to wind the excess length of the raw silk around the outside of the take-up reel 73, gradually tightening the raw silk into a horizontal straight line. This is achieved by using... Figure 5 The limiting block 13 shown engages with the meshing structure of the toothed disc 74, which facilitates control that the toothed disc 74 and the winding wheel 73 can only rotate in one direction, thus ensuring the stability of the raw silk winding.

[0039] Following the above method, multiple strands of raw silk are installed and tightened sequentially. Then, the blade holder mechanism 17 is closed, so that the upper blade holder is placed horizontally on the raw silk, allowing the raw silk to rub against the friction blade holder. Subsequently, the drive motor 81 is started to control the disc 82 and the fixed column 83 to rotate at a uniform speed. The fixed column 83 can press the vertical rod 18, which has a through groove structure inside, so that the vertical rod 18 can drive the base 16 and the blade holder mechanism 17 to move back and forth synchronously along the horizontal bar 3. This facilitates the detection of the cohesion of the raw silk. Moreover, when the vertical rod 18 moves back and forth, it can pass directly above the infrared counting sensor 19, which makes it convenient to accurately count the number of frictions and feed the data back to the external controller display screen, so as to obtain accurate detection results.

[0040] After the test is completed, the movable rod 11 can be controlled by the electric push rod 10 to move vertically downward along the slide groove 9, so that multiple limit blocks 13 can move away from multiple toothed discs 74 at the same time and disengage. At this time, under the action of the coil spring 72, multiple winding wheels 73 can be synchronously rotated and reset. Compared with the comparison document, this device does not need to be manually adjusted one by one when adjusting and resetting, making the operation more convenient, simple, and efficient.

[0041] It should be noted that this device is powered by an external power source. The drive motor 81, electric push rod 10 and infrared counting sensor 19 in the solution are all existing products and are controlled by an external controller. Their specific power supply methods, working principles and control methods are all mature technologies. Moreover, the tool holder overall mechanism 17 in this solution directly references the prior art and is not the key innovation direction of this case, so it will not be described in detail.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
