Description

Technical Field

[0001] The present invention relates to the technical field of long-staple cotton detection, and particularly to a stretching detection device for long-staple cotton used in optics. Background Art

[0002] During the processing of long-staple cotton, it is necessary to perform stretching detection on the long-staple cotton to understand whether the quality of the long-staple cotton is qualified and ensure that there are no problems in the subsequent use of the long-staple cotton due to unqualified quality.

[0003] Currently, mechanical stretching method is usually adopted for the stretching detection of long-staple cotton. It is necessary to heat the long-staple cotton to a specified temperature and then place it on the detection machine. However, after the long-staple cotton is heated to the specified temperature by a heater, it is necessary to use a clamp to hold the long-staple cotton and move it to the detection machine for stretching detection. During the process from being clamped by the clamp to being placed in the detection machine after the long-staple cotton is heated, it is easy to cause heat loss of the long-staple cotton, affect the temperature of the long-staple cotton, resulting in deviation in the stretching detection, and it takes time during the process of clamping and placing, affecting the efficiency of the stretching detection.

[0004] Therefore, it is necessary to design a stretching detection device for long-staple cotton used in optics that can directly perform stretching detection after heating the long-staple cotton, so that the long-staple cotton does not need to be moved and the temperature can be kept stable, improving the accuracy and efficiency of the stretching detection. Summary of the Invention

[0005] In order to overcome the disadvantages that during the process from being clamped by the clamp to being placed in the detection machine after the long-staple cotton is heated, it is easy to cause heat loss of the long-staple cotton, affect the temperature of the long-staple cotton, resulting in deviation in the stretching detection, and it takes time during the process of clamping and placing, affecting the efficiency of the stretching detection, the present invention provides a stretching detection device for long-staple cotton used in optics that can directly perform stretching detection after heating the long-staple cotton, so that the long-staple cotton does not need to be moved and the temperature can be kept stable, improving the accuracy and efficiency of the stretching detection.

A driving component is arranged on the outer side of the frame body to drive the rotating shaft to rotate.

[0012] Further description, the sealing component further includes a diversion plate fixedly connected to the inner side of the swinging frame to divert part of the air.

[0013] Further description, the driving component includes a swinging block fixedly sleeved on the end of the rotating shaft. The swinging block is located outside the frame body.

[0014] Further description, the long-staple cotton drafting detection device for optics further includes a guiding frame communicated with the bottom of the frame body. A collecting frame is slidably connected to the inner side of the guiding frame. The collecting frame is communicated with the inside of the frame body to collect cotton fluffs.

[0015] The remarkable progress of the present invention lies in:

[0016] 1. First, place the long-staple cotton on the support plate. Then start the heater to heat the long-staple cotton to the specified temperature. Then start the electric screw rod to move the clamping plate I and the clamping plate II to the specified position. The clamping plate II contacts the long-staple cotton. Start the single-rod cylinder to drive the clamping plate I to move downward to cooperate with the clamping plate II to clamp and fix the long-staple cotton. Then the drafting detection of the long-staple cotton can be started, so that the drafting detection can be completed without moving the long-staple cotton for clamping, thereby improving the accuracy of the drafting detection.

[0017] 2. Under the action of the double-sided brush plate, whenever the clamping plate I moves upward to reset, the movement of the double-sided brush plate can remove the cotton fluffs attached to the clamping plate I and the clamping plate II, so as to prevent the attachment of cotton fluffs from affecting the collection and treatment, thereby ensuring that the cotton fluffs are fully collected.

[0018] 3. Under the action of the swinging frame, whenever the long-staple cotton starts the drafting detection, the swinging frames on the front and rear sides can contact each other to form a semi-closed space, which can block the cotton fluffs. The cotton fluffs are blown away by the air, which can prevent some cotton fluffs from floating around and affecting the air quality, thereby ensuring good air quality around.

Tensile testers 21 are installed in the middle of the n-shaped plates 2 on both the left and right sides. The tensile testers 21 are connected to the movable seats 3. An electric screw rod 9 is installed on the front side of the frame body 1. The threads on the left and right sides of the electric screw rod 9 are opposite. The electric screw rod 9 is threadedly connected to the front sides of the n-shaped plates 2 on both the left and right sides. It also includes a mounting plate 10, a heater 101, a support plate 102, a driving motor 103, a movable plate 104, a guide rod 105, a return spring 106, a jetting component and a cleaning component. The jetting component is installed on the frame body 1. When the jetting component operates, the jetting component can blow the cotton fluffs out of the frame body 1. Mounting plates 10 are fixedly connected symmetrically before and after in the middle of the frame body 1. Heaters 101 are installed on both the front and rear mounting plates 10. The bottom of the front mounting plate 10 is rotatably connected with a support plate 102. The rear side of the support plate 102 contacts the rear mounting plate 10. The bottom of the support plate 102 is slidably connected with movable plates 104 symmetrically left and right. Four guide rods 105 are fixedly connected to the bottom of the support plate 102 at equal intervals. The left and right guide rods 105 are respectively slidably connected to the bottoms of the left and right movable plates 104. A return spring 106 is connected between the guide rod 105 and the bottom of the movable plate 104. A driving motor 103 is installed at the lower right part of the front mounting plate 10.

When the long-staple cotton is placed on the support plate 102, the movable plate 104 supports the long-staple cotton. The heater 101 is started to heat the long-staple cotton to a specified temperature. Then the driving motor 103 is started to rotate forward to drive the support plate 102 to swing downward. The support plate 102 drives the movable plate 104 to swing downward. The swinging of the support plate 102 and the movable plate 104 does not affect the downward dropping of the cotton fluffs. Subsequently, the clamping plate I 6 and the clamping plate II 8 cooperate to pull the long-staple cotton to complete the drafting detection. The cleaning component is installed between the U-shaped seat 5 and the clamping plate I 6. When the cleaning component operates, the cleaning component can remove the cotton fluffs attached to the clamping plate I 6 and the clamping plate II 8.

[0033] Please refer to Figure 6 As shown, the jet component includes a jet pipe 11 and an intake pipe 111. The jet pipes 11 are symmetrically and fixedly connected to the front and rear sides inside the frame 1. The jet end of the jet pipe 11 faces downward. The jet pipe 11 can blow the cotton wool downward with air. An intake pipe 111 is connected between the left ends of the jet pipes 11 on the front and rear sides. The intake pipe 111 is located outside the frame 1.

[0034] Please refer to Figure 7 and Figure 8 As shown, the cleaning component includes a double-sided brush plate 12, a rotating rod 1201, a belt assembly 121, a connecting rod 122, a torsion spring I 123 and a trigger component. The double-sided brush plates 12 are horizontally and slidably inserted through the middle parts of the U-shaped seats 5 on the left and right sides. When the double-sided brush plate 12 moves and contacts the clamping plate I 6 and the clamping plate II 8, the double-sided brush plate 12 can clean the cotton wool attached to the clamping plate I 6 and the clamping plate II 8. The rotating rods 1201 are symmetrically and rotatably connected to the front and rear sides of the U-shaped seats 5 on the left and right sides. A belt assembly 121 is connected between the upper and lower rotating rods 1201. The connecting rods 122 are fixedly sleeved on the lower front and rear rotating rods 1201. The tops of the front and rear connecting rods 122 are respectively slidably connected to the front and rear side surfaces of the double-sided brush plate 12. When the connecting rod 122 swings, the connecting rod 122 can drive the double-sided brush plate 12 to move horizontally. A torsion spring I 123 is connected between the lower rotating rod 1201 and the inner side of the U-shaped seat 5. A trigger component is arranged between the upper rotating rod 1201 and the clamping plate I 6. When the trigger component operates, the trigger component can drive the rotating rod 1201 to rotate; the trigger component includes a contact rod 124, a trigger rod 125 and a torsion spring II 126. The contact rod 124 is fixedly sleeved on the upper rotating rod 1201. The contact rod 124 is located inside the U-shaped seat 5. The trigger rods 125 are symmetrically and rotatably connected to the front and rear sides on the left side of the clamping plate I 6. The trigger rods 125 correspond to the contact rod 124. The trigger rods 125 can drive the contact rod 124 to swing. A torsion spring II 126 is connected between the trigger rods 125 and the clamping plate I 6.

[0035] First, place three groups of long-staple cotton on the support plate 102. Then, start the heater 101 to heat the long-staple cotton to the specified temperature. Start the electric screw rod 9 to drive the n-shaped plates 2 on the left and right to move towards each other. The n-shaped plates 2 drive the movable seats 3 on the left and right to move towards each other. The movable seats 3 drive the U-shaped plates 4 on the left and right to move towards each other. The U-shaped plates 4 drive the clamping plates I 6 and the clamping plates II 8 on the left and right to move towards each other. The clamping plates II 8 contact the movable plate 104, and the clamping plates II 8 drive the movable plates 104 on the left and right to move towards each other. The return spring 106 is compressed. When the movable plates 104 on the left and right retract into the support plate 102, turn off the electric screw rod 9. The clamping plates II 8 contact the long-staple cotton for support. Then, start the telescopic rod of the single-rod cylinder 7 to extend and drive the clamping plate I 6 to move downward. The clamping plate I 6 moves downward and drives the trigger rod 125 to move downward. The trigger rod 125 moves downward and contacts the contact rod 124. The contact rod 124 drives the trigger rod 125 to swing upward. The torsion spring II 126 is compressed. As the trigger rod 125 continues to move downward and disengages from the contact rod 124, due to the action of the torsion spring II 126, the trigger rod 125 swings downward to reset. When the clamping plate I 6 moves downward and contacts the long-staple cotton, the clamping plate I 6 and the clamping plate II 8 cooperate to clamp and fix the long-staple cotton. Turn off the single-rod cylinder 7. Start the driving motor 103 to rotate forward and drive the support plate 102 to swing downward. The support plate 102 swings downward and disengages from the long-staple cotton. And the support plate 102 drives the movable plate 104 to swing downward. The movable plate 104 disengages from the clamping plate II 8. Due to the action of the return spring 106, the movable plates 104 on the left and right move away from each other to reset. Connect the air inlet pipe 111 to an external air pump. Start the external air pump to discharge air into the air inlet pipe 111. The air in the air inlet pipe 111 is discharged into the air spray pipe 11. The air spray pipe 11 sprays air into the frame 1. The air flows along the inner wall of the frame 1. Then, start the electric screw rod 9 to drive the n-shaped plates 2 on the left and right to move away from each other. The n-shaped plates 2 drive the movable seats 3 on the left and right to move away from each other through the tensile tester 21, so that the clamping plates I 6 and the clamping plates II 8 on the left and right pull the two ends of the long-staple cotton to move away from each other, and thus the long-staple cotton is subjected to draft detection. The tensile tester 21 obtains the draft value. When the long-staple cotton breaks, turn off the electric screw rod 9. The clamping plates I 6 and the clamping plates II 8 stop pulling the long-staple cotton. The cotton fluffs generated during the breaking process fall downward into the frame 1. The cotton fluffs contact the flowing air, and the air drives the cotton fluffs to move downward and be discharged and collected from the frame 1. Then, the value obtained by the tensile tester 21 can be checked to understand whether the strength of the long-staple cotton is qualified. And start the telescopic rod of the single-rod cylinder 7 to shorten and drive the clamping plate I 6 to move upward to reset. The clamping plate I 6 drives the trigger rod 125 to move upward. The trigger rod 125 contacts the contact rod 124. The trigger rod 125 drives the contact rod 124 to swing upward. The contact rod 124 swings and drives the upper rotating rod 1201 to rotate. The upper rotating rod 1201 drives the belt assembly 121 to rotate.The belt assembly 121 drives the lower rotating rod 1201 to rotate, the torsion spring I 123 is compressed, the lower rotating rod 1201 drives the connecting rod 122 to swing downward, and the downward swing of the connecting rod 122 drives the two-way brush plates 12 on both the left and right sides to move towards each other. The movement of the two-way brush plates 12 removes the cotton fluffs attached to the clamping plate I 6 and the clamping plate II 8, preventing the attachment of cotton fluffs from affecting the collection and processing, thereby ensuring the complete collection of cotton fluffs. As the trigger rod 125 continues to move upward and reset, the trigger rod 125 disengages from the contact rod 124. Due to the action of the torsion spring I 123, the lower rotating rod 1201 rotates in the reverse direction and drives the two-way brush plates on both the left and right sides to move away from each other and reset through the connecting rod 122. The lower rotating rod 1201 drives the upper rotating rod 1201 to rotate in the reverse direction and reset through the belt assembly 121, which also causes the contact rod 124 to swing downward and reset. After the drafting detection of long-staple cotton is completed, the driving motor 103 is started to drive the support plate 102 to swing upward and reset, and the support plate 102 drives the movable plate 104 to swing upward and reset, and the heater 101 is turned off. In this way, after the long-staple cotton is heated by the heater 101, the clamping plate I 6 and the clamping plate II 8 can directly clamp and fix the long-staple cotton for drafting detection, without the need to move the long-staple cotton for clamping to complete the drafting detection, thereby improving the accuracy of the drafting detection.,

[0036] Please refer to Figure 9 and Figure 10As shown in the figure, the long-staple cotton drafting detection device for optics further includes a sealing component installed between the frame 1 and the movable seat 3. The sealing component includes a rotating shaft 13, a swinging frame 131, a corrugated cover 132, a sliding block 133, a connecting rod 134, a diversion plate 135 and a driving component. The rotating shaft 13 is rotatably penetrated through the front and rear of the frame 1 symmetrically. The swinging frames 131 are fixedly connected to the middle parts of the rotating shafts 13 on the front and rear sides. The diversion plates 135 are fixedly connected to the inner sides of the swinging frames 131 on the front and rear sides. When the diversion plate 135 swings to a suitable position, the diversion plate 135 can divert part of the air. The corrugated covers 132 are slidably sleeved on the rotating shaft 13 symmetrically from left to right. The end parts of the corrugated covers 132 on the left and right sides close to each other are fixedly connected to the left and right sides of the swinging frame 131 respectively. The sliding blocks 133 are slidably sleeved on the rotating shaft 13 symmetrically from left to right. The lower parts of the sliding blocks 133 on the left and right sides are rotatably connected to the shaft parts of the corrugated covers 132 on the left and right sides respectively. Two connecting rods 134 are fixedly connected between the upper parts of the sliding blocks 133 and the corresponding movable seats 3. A driving component is arranged on the outer side surface of the frame 1. When the driving component operates, the driving component can drive the rotating shaft 13 to rotate. The driving component includes a swinging block 136, a slotted plate 137 and a double-rod cylinder 138. The swinging blocks 136 are fixedly sleeved on the right ends of the rotating shafts 13 on the front and rear sides. The swinging blocks 136 are located outside the frame 1. The slotted plate 137 is vertically slidably connected to the outer right side surface of the frame 1. The slotted plate 137 is slidably connected to the swinging blocks 136 on the front and rear sides. When the slotted plate 137 moves up and down, the slotted plate 137 can drive the swinging block 136 to swing. The double-rod cylinder 138 is fixedly connected to the lower part of the outer right side surface of the frame 1. The end of the telescopic rod of the double-rod cylinder 138 is fixedly connected to the bottom of the slotted plate 137.

[0037] When the long-staple cotton is placed on the support plate 102 and heated by the heater 101, first start the double-rod cylinder 138 to shorten its telescopic rod, which drives the one-hole plate 137 to move downward. The one-hole plate 137 drives the swing block 136 to swing downward, the swing block 136 drives the rotating shaft 13 to rotate, the rotating shaft 13 drives the swing frames 131 on the front and rear sides to swing towards each other, and the swing frames 131 drive the guide plates 135 on the front and rear sides to swing towards each other. Then, when the swing frames 131 on the front and rear sides come into contact with each other, turn off the double-rod cylinder 138. The swing frames 131 on the front and rear sides come into contact with each other to form a semi-closed space. Subsequently, the electric screw rod 9 drives the n-shaped plates 2 on the left and right sides to move towards each other. The movable seat 3 drives the sliding blocks 133 on the left and right sides to move towards each other through the connecting rod 134. The sliding block 133 moves to compress the corrugated cover 132. Then, when the clamping plate Ⅰ6 and the clamping plate Ⅱ8 move to the designated position, turn off the electric screw rod 9, so that the clamping plate Ⅰ6 and the clamping plate Ⅱ8 can clamp and fix the long-staple cotton. When the air jet pipe 11 ejects air, part of the air contacts the guide plate 135, and the guide plate 135 makes the air flow upward into the swing frame 131. When the clamping plate Ⅰ6 and the clamping plate Ⅱ8 pull the two ends of the long-staple cotton to move away from each other, the movable seat 3 drives the sliding block 133 to move back through the connecting rod 134, which also makes the corrugated cover 132 move back. Then, when the long-staple cotton breaks, the cotton fluffs float in the swing frame 131, and the swing frame 131 blocks the cotton fluffs. Since air flows into the swing frame 131, the air blows the cotton fluffs into the frame body 1 and discharges them for collection. When the stretching detection of the long-staple cotton is completed, start the telescopic rod of the double-rod cylinder 138 to extend, which drives the one-hole plate 137 to move upward and reset. The one-hole plate 137 drives the rotating shaft 13 to rotate reversely and reset through the swing block 136, which also makes the swing frames 131 on the front and rear sides swing back away from each other. In this way, it can prevent some cotton fluffs from floating around and affecting the air quality, thus ensuring good air quality around.

[0038] Please refer to Figure 11 As shown in the figure, the long-staple cotton stretching detection device for optics further includes a guide frame 14 and a collection frame 15. The middle of the bottom of the frame body 1 is communicated with the guide frame 14. The collection frame 15 is slidably connected to the inside of the guide frame 14. The collection frame 15 is communicated with the inside of the frame body 1, and the collection frame 15 can collect the cotton fluffs.

[0039] Initially, the collection frame 15 is filled with an appropriate amount of water. When the cotton fluffs are discharged from the frame body 1 and enter the collection frame 15, the water in the collection frame 15 contacts the cotton fluffs, making it difficult for the cotton fluffs to float. Then the collection frame 15 collects and processes the cotton fluffs. When the collection frame 15 is filled with an appropriate amount of cotton fluffs, pull the collection frame 15 forward to separate it from the guide frame 14, and then the cotton fluffs in the collection frame 15 can be poured out for processing. After all the cotton fluffs are poured out, put the collection frame 15 back into the guide frame 14. In this way, it is more convenient to collect the discharged cotton fluffs.
