Specifically, as Figure 2 As shown, the cotton core support assembly 2 is used to place the cotton core. The cotton core pusher assembly 3 specifically includes a driving device 31 and a clamping device 32, and the driving device 31 is arranged on the frame 1, and is used to drive the clamping device 32 to move along a preset direction, and the clamping device 32 is connected to the driving device 31, and is used to clamp the cotton core in the cotton core support assembly 2. The driving assembly 4 is arranged on the frame 1 and is located above the cotton core support assembly 2, and the driving assembly 4 specifically includes a guide shaft 41 and a moving device 42, and the guide shaft 41 is arranged on the frame 1, and the moving device 42 is slidably arranged on the guide shaft 41, and the moving device 42 is also connected to the driving device 31 of the cotton core pusher assembly 3, and is used to drive the cotton core pusher assembly 3 to slide along the axial direction of the guide shaft 41. The guide rail 5 is arranged on the frame 1, and the head assembly 6, the guide assembly 7, the sleeve support assembly 8 and the cotton suction line assembly 9 can all be slidably arranged on the guide rail 5. The head assembly 6 is located below the guide shaft 41 and has at least one petal head 61; the guide assembly 7 is located below the head assembly 6 and has at least one guide cone barrel 71, and the number of the guide cone barrels 71 is the same as the number of the petal heads 61 and corresponds to each other; the sleeve support assembly 8 is located below the guide assembly 7 and is used to support the single board fixture on which the sleeve is placed, and is used to push each sleeve on the single board fixture into the corresponding guide cone barrel 71, and the sleeve support assembly 8 is also used to receive the cotton core clamped by the clamping device 32 after the sleeve is pushed into the corresponding guide cone barrel 71. In addition, the driving assembly 4 is also used to drive the cotton core in the sleeve support assembly 8 to move, so that the cotton core in the sleeve support assembly 8 is pushed into the sleeve. The cotton suction line assembly 9 is arranged below the sleeve support assembly 8 and is used to slide along the length direction of the guide rail 5, and the cotton suction line assembly 9 is also used to generate negative pressure when sliding to a preset position, straighten the cotton thread at the end of the cotton core, and avoid bending of the cotton thread.

Further, any one of the two motion devices 42 is arranged on the first synchronous belt 45, and the other motion device 42 is arranged on the second synchronous belt 48. As a specific implementation method, the guide shaft 41 can be a linear shaft, which is arranged on the frame 1. The moving device 42 can be a linear bearing arranged on the linear shaft. The driving device 31 of the cotton core pushing assembly 3 is arranged on the linear bearing. When the first driving motor 43 is working, the first transmission shaft 44 is driven to rotate through the first synchronous belt 45. At the same time, the second synchronous belt 48 is driven to move through the first transmission shaft 44, so that the first synchronous belt 45 and the second synchronous belt 48 move synchronously, and then the two moving devices 42 move along the corresponding guide shaft 41 at the same time, driving the cotton core pushing assembly 3 to move along the axial direction of the guide shaft 41.

Among them, the second drive motor 62 is arranged on the frame 1, and the second transmission shaft 63 and the second driven wheel 64 are rotatably arranged on the frame 1. Further, the second synchronous pulley 612 is arranged on the motor shaft of the second drive motor 62, the second transmission shaft 63 and the second synchronous pulley 612 are arranged opposite to each other, and the second driven wheel 64 and the second drive motor 62 are arranged opposite to each other, and the third synchronous belt 65 and the fourth synchronous belt 66 are respectively arranged at both ends of the second transmission shaft 63, and the second synchronous pulley 612 and the second transmission shaft 63 are connected by the third synchronous belt 65, and the second transmission shaft 63 and the second driven wheel 64 are connected by the fourth synchronous belt 66. Two second slide rails 67 are arranged in parallel on the frame 1 and are respectively located below the third synchronous belt 65 and the fourth synchronous belt 66. Two second sliders 68 are respectively arranged on the third synchronous belt 65 and the fourth synchronous belt 66, and each second slider 68 is arranged corresponding to each second slide rail 67, that is, the two second sliders 68 are used to slide along the length direction of the corresponding second slide rail 67 when the second drive motor 62 moves. The support plate 69 connects the two second sliders 68, the first cylinder 610 is arranged on the support plate 69 and has a telescopic rod, the push rod mounting plate 611 is arranged on the telescopic rod, and each petal top 61 is arranged on the push rod mounting plate 611. Therefore, when the first cylinder 610 is working, the telescopic rod moves up and down, driving the push rod mounting plate 611 to move up and down, thereby allowing each petal top 61 to move up and down, and then the petals at the top of each sleeve can be pushed open.

[0112] Further, such as Fig. 20 , Fig.21 As shown, the cotton suction line assembly 9 may specifically include: a third slider 91, a second cylinder 92 and an air suction component 93. Specifically, the third slider 91 is disposed on the guide rail 5 and is used to slide along the length direction of the guide rail 5. The second cylinder 92 is disposed on the frame 1. The air suction component 93 is disposed on the third slider 91 and is connected to the second cylinder 92. The air suction component 93 is also connected to the fan duct to generate negative pressure. In actual use, the air suction component 93 may be a fan or an air pump, etc. In addition, as Fig.19 As shown, the guide assembly 7 also includes: a fourth cylinder 72 arranged on the frame 1, and a cone barrel fixing plate 73 connected to the telescopic rod of the fourth cylinder 72, wherein each guide cone barrel 71 is arranged on the cone barrel fixing plate 73.

[0113] It should be noted that, in this embodiment, Fig.24 , Fig.25As shown, the cotton strip assembly system may also include: a cotton thread detection component, a waste lifting fixture component 10, a main control module and a waste conveying component 20. Specifically, the cotton thread detection component is arranged on the frame 1, and is used to detect whether the position of the cotton core in each sleeve is correct. The waste lifting fixture component 10 is arranged at the next station of the cotton thread detection component, and the main control module is electrically connected to the cotton thread detection component and the waste lifting fixture component 10 respectively. The waste conveying component 20 is arranged below the waste lifting fixture component 10, and is used to transport the sleeve component clamped by the waste lifting fixture component 10. Further, the main control module is used to record the detection result of the cotton thread detection component. In addition, the main control module is also used to control the waste lifting fixture component 10 to clamp the corresponding sleeve assembly when the detection result detected by the cotton thread detection component is different from the preset result, and the corresponding sleeve assembly is placed on the waste conveying component 20, and the sleeve assembly is transported away by the waste conveying component 20, so as to improve the qualified rate of the sleeve and cotton core assembly finished product.

[0114] Furthermore, the cotton thread detection component can be a light switch, specifically including a light emitting end and a light receiving end. Under normal circumstances, the light emitted by the light emitting end can be sent and received by the light receiving end. When the cotton core and the sleeve are assembled and pass through the cotton core detection component, the cotton thread at the end of the cotton core passes between the light emitting end and the light receiving end, so that the light receiving end cannot receive the light emitted by the light emitting end. In other words, when the cotton core and the sleeve are assembled and moved from the previous workstation to the cotton thread detection component, each light receiving end cannot receive the light emitted by the light emitting end. When a certain light receiving end can still receive the light emitted by the light emitting end, it proves that the assembly of the cotton core and the sleeve at this position is incorrect. Fig.24 As shown, the waste lifting fixture assembly 10 includes: a cylinder mounting plate 101, a third cylinder 102, a finger-actuated cylinder mounting plate 103 and a plurality of finger-actuated cylinders 104. Among them, the cylinder mounting plate 101 is arranged on the frame 1, the third cylinder 102 is arranged on the cylinder mounting plate 101, the finger-actuated cylinder mounting plate 103 is arranged on the third cylinder 102, and moves up and down with the movement of the third cylinder 102, and each finger-actuated cylinder 104 is arranged on the finger-actuated cylinder mounting plate 103 along the length direction of the finger-actuated cylinder mounting plate 103, and the finger-actuated cylinder 104 is used to clamp the sleeve assembly corresponding to the detection result detected by the cotton thread detection assembly when it is different from the preset result. In actual use, the waste conveying assembly 20 can be a synchronous belt assembly, and the main control module can be a single-chip microcomputer.

[0115] During actual use, when the cotton core and the sleeve are assembled, first, when the single plate clamp moves from the previous workstation to the guide cone assembly, the sleeve support assembly 8 moves upward to push each sleeve into the corresponding guide cone barrel 71. At this time, each petal head 61 on the head assembly 6 moves downward to open the petals on the upper part of the sleeve. Then, the head assembly 6 retracts and moves upward, and then, the cotton core pushing assembly 3 clamps the cotton core in the cotton core support assembly 2 and slides along the axial direction of the guide shaft 41. After the cotton core pushing assembly 3 moves to the preset position, the clamping device 32 releases the cotton core, so that the cotton core falls into the sleeve support assembly 8, and the nylon push head 3143 on each push rod 3142 pushes the cotton core into the sleeve through the guide cone barrel 71. At the same time, the negative pressure generated by the suction component 93 pulls the cotton thread to the rear end to prevent the cotton thread from bending. After the cotton core is installed in the sleeve, the suction component 93 stops working, each push rod 3142 is removed, and the single-board fixture moves forward to the next station. The cotton thread detection component detects whether the cotton thread of the cotton core in each sleeve is in the correct position, and the main control module records it. Then the single-board fixture continues to move forward to the next station, and the waste clamp assembly 10 clamps out the sleeve whose detection result of the cotton thread detection component is different from the preset result, and after the single-row fixture moves backward to the next station, the sleeve corresponding to the different detection result from the preset result is thrown into the waste conveying assembly 20 for transportation. In this way, the automatic assembly of the cotton core and the sleeve can be realized, labor can be saved, production efficiency can be effectively improved, and no manual operation is required, bacteria can be avoided in the cotton core, and the qualified rate of the assembly of the cotton core and the sleeve can be improved.
