Description

Technical Field

[0001] This utility model relates to the field of air-jet spinning equipment technology, and specifically to an anti-collision device for air-jet spinning equipment. Background Technology

[0002] Air-jet spinning equipment is a new type of spinning equipment that uses airflow to condense and twist fibers in a high-speed rotating spinning cup to output yarn. It mainly consists of multiple components such as carding rollers, spinning cups, and false twisting devices. During the spinning process, workers often accidentally press the emergency stop button, causing the equipment to stop. Because the various components of the air-jet spinning equipment are closely coordinated when running at high speed, accidental presses by workers can affect the stable operation of the entire production process and even cause equipment failure. Therefore, it is particularly important to take anti-collision measures for air-jet spinning equipment.

[0003] The prior art, Chinese patent with authorization announcement number CN207597021U, discloses an anti-collision device for air-jet spinning equipment. When the emergency stop button needs to be pressed, pulling the baffle upwards will pull the rectangular plate out of the rectangular groove. The spring returns and actuates the second connecting rod, which pushes the slide plate. The slide plate pushes the convex block to collide with the emergency stop button, thus activating the emergency stop button. This avoids trouble and losses caused by accidental collision with the emergency stop button. It is safe and reliable to use and avoids misoperation.

[0004] The existing technical solutions mentioned above have the following drawbacks: by pushing the convex block to collide with the emergency stop button by the sliding plate, the convex block still contacts the emergency stop button and applies pressure to it after the emergency stop button is activated. The emergency stop button is usually designed to be pressed and released quickly in an emergency. Holding the emergency stop button for a long time may cause the contacts to overheat, stick or be damaged, or even cause equipment failure and increase maintenance costs.

[0005] Therefore, an anti-collision device for air-jet spinning equipment is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide an anti-collision device for air-jet spinning equipment in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] An anti-collision device for an air-jet spinning machine includes the air-jet spinning machine itself. An emergency stop button is fixedly installed on the surface of the air-jet spinning machine. An anti-collision shell is fixedly installed on the surface of the air-jet spinning machine, located outside the emergency stop button. An upper baffle is fixedly installed on the inner wall surface of the anti-collision shell. An automatic reset mechanism is provided between the opposing surfaces of the anti-collision shell and the upper baffle. Two fixing mechanisms are provided on the surface of the anti-collision shell and are arranged symmetrically front and back. A through groove is opened on the bottom surface of the anti-collision shell. A lower baffle is slidably installed on the inner wall surface of the through groove. A limit plate is fixedly installed on the surface of the lower baffle. A pushing mechanism is provided on the right side of the anti-collision shell.

[0009] Furthermore, the automatic reset mechanism includes a sleeve rod, which is fixedly installed on the inner wall surface of the anti-collision shell. There are two sleeve rods arranged one in front of the other. A limit block is slidably installed on the inner wall surface of the sleeve rod. A first spring is fixedly connected between the limit block and the opposite surface of the sleeve rod. A sliding rod is fixedly installed on the side surface of the limit block away from the first spring. The sliding rod is slidably arranged relative to the inner wall surface of the sleeve rod. A push plate is fixedly installed on the end surface of the sliding rod away from the limit block. A receiving groove is opened on the surface of the upper baffle. The size of the push plate is adapted to the receiving groove.

[0010] Furthermore, the fixing mechanism includes a slide groove, which is formed on the surface of the anti-collision shell. A fixing head is slidably installed on the inner wall surface of the slide groove. A connecting rod is fixedly installed on the surface of the fixing head. A pulling plate is fixedly installed on the surface of the connecting rod. A telescopic rod and a second spring are fixedly installed between the pulling plate and the opposite surface of the anti-collision shell. The second spring is located outside the telescopic rod.

[0011] Furthermore, the fixing head has a U-shaped structure.

[0012] Furthermore, the pushing mechanism includes a push rod, which is slidably mounted on the right side of the anti-collision housing. A push head is fixedly mounted on the right side surface of the push rod, and a connecting plate is fixedly mounted on the left side surface of the push rod. An upper protrusion and a lower protrusion are fixedly mounted on the left side surface of the connecting plate, with the upper protrusion located above the lower protrusion.

[0013] Furthermore, the surface of the pusher head is provided with rubber strips, which are evenly distributed around the surface of the pusher head.

[0014] The beneficial effects of this utility model are as follows: When an emergency stop is required for the air-jet spinning equipment, the fixing mechanism is pulled to both sides to release the fixing of the lower baffle. At this time, the lower baffle slides down the inner wall surface of the channel under the action of gravity. The setting of the limiting plate prevents the lower baffle from slipping off the surface of the channel. Pushing the pushing mechanism to the left applies pressure to the emergency stop button and the automatic reset mechanism. The emergency stop button is opened under the action of the pushing mechanism. Then, the pushing mechanism is released. Under the action of the elastic force inside the automatic reset mechanism, the pushing mechanism returns to its original position. After the emergency stop effect is triggered, the pushing mechanism can quickly separate from the emergency stop button. Pulling the fixing mechanism pushes the lower baffle upward. When the limiting plate is above the fixing mechanism, the fixing mechanism is released. The lower baffle can be fixed by limiting the limiting plate, thereby achieving the anti-collision effect of the air-jet spinning equipment. It is not easy to cause problems such as overheating, adhesion or damage of the contact points, reducing the risk of equipment failure and helping to reduce maintenance costs.

[0023] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0024] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use.

Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1 to 4 As shown, an anti-collision device for an air-jet spinning machine includes an air-jet spinning machine 1, an emergency stop button 2 fixedly installed on the surface of the air-jet spinning machine 1, an anti-collision housing 3 fixedly installed on the surface of the air-jet spinning machine 1, the anti-collision housing 3 being located outside the emergency stop button 2, an upper baffle 4 fixedly installed on the inner wall surface of the anti-collision housing 3, an automatic reset mechanism 5 provided between the opposing surfaces of the anti-collision housing 3 and the upper baffle 4, a fixing mechanism 6 provided on the surface of the anti-collision housing 3, two fixing mechanisms 6 being arranged symmetrically front and back, a through groove 10 opened on the bottom surface of the anti-collision housing 3, a lower baffle 7 slidably installed on the inner wall surface of the through groove 10, a limit plate 8 fixedly installed on the surface of the lower baffle 7, and a pushing mechanism 9 provided on the right side of the anti-collision housing 3.

[0026] Specifically, when an emergency stop is required for the air-jet spinning equipment 1, the fixing mechanism 6 is pulled to both sides to release the fixing mechanism 6 from the lower baffle 7. At this time, the lower baffle 7 slides down the inner wall surface of the through groove 10 under the action of gravity. The limiting plate 8 prevents the lower baffle 7 from slipping off the surface of the through groove 10. At this time, the movement of the pushing mechanism 9 is not blocked by the lower baffle 7. Pushing the pushing mechanism 9 to the left causes the pushing mechanism 9 to apply pressure to the emergency stop button 2 and the automatic reset mechanism 5. The emergency stop button 2 is opened under the action of the pushing mechanism 9, and then the pushing mechanism 9 is released. Driven by the elastic force inside the automatic reset mechanism 5, the push mechanism 9 returns to its original position. After triggering the emergency stop effect, the push mechanism 9 can quickly separate from the emergency stop button 2, pull the fixing mechanism 6 and push the lower baffle 7 upward until the fixing mechanism 6 is released and then contacts the lower baffle 7 under the action of the elastic force. The lower baffle 7 is further fixed by the limiting plate 8, thus achieving the anti-collision effect of the air-jet spinning equipment 1. It is not easy to cause problems such as overheating, adhesion or damage of the contact points, reducing the risk of equipment failure and helping to reduce maintenance costs.

[0027] like Figure 2 and Figure 3 As shown, the automatic reset mechanism 5 includes a sleeve rod 501, which is fixedly installed on the inner wall surface of the anti-collision housing 3. There are two sleeve rods 501 arranged in a front-to-back configuration. A limit block 502 is slidably installed on the inner wall surface of the sleeve rod 501. A first spring 503 is fixedly connected between the opposite surfaces of the limit block 502 and the sleeve rod 501. A slide rod 504 is fixedly installed on the side surface of the limit block 502 away from the first spring 503. The slide rod 504 is slidably arranged relative to the inner wall surface of the sleeve rod 501. A push plate 505 is fixedly installed on the end surface of the slide rod 504 away from the limit block 502. A receiving groove 506 is opened on the surface of the upper baffle 4. The size of the push plate 505 is adapted to the receiving groove 506.

[0028] Specifically, when the push mechanism 9 is moved to the right, it contacts the emergency stop button 2 and the push plate 505 simultaneously, pushing the push plate 505 to the left along the inner wall surface of the receiving groove 506. The slide rod 504 and the limit block 502 slide along the inner wall surface of the sleeve rod 501. At the same time, the first spring 503 deforms under the force. When the emergency stop button 2 is activated, the push mechanism 9 is released. Under the elastic restoring force of the first spring 503, the limit block 502 and the slide rod 504 are pushed to the right, which in turn drives the push plate 505 to push the push mechanism 9 to the right until it returns to its original position. After the emergency stop effect is triggered, the push mechanism 9 can quickly separate from the emergency stop button 2, which is less likely to cause problems such as overheating, sticking or damage of the contacts, thus reducing the risk of equipment failure.

[0029] like Figure 1 and Figure 4As shown, the fixing mechanism 6 includes a slide groove 606, which is formed on the surface of the anti-collision shell 3. A fixing head 601 is slidably installed on the inner wall surface of the slide groove 606. A connecting rod 602 is fixedly installed on the surface of the fixing head 601. A pulling plate 603 is fixedly installed on the surface of the connecting rod 602. A telescopic rod 604 and a second spring 605 are fixedly installed between the pulling plate 603 and the opposite surface of the anti-collision shell 3. The second spring 605 is located outside the telescopic rod 604.

[0030] Specifically, when the fixing mechanism 6 limits the lower baffle 7, it can achieve the anti-collision effect of the air-jet spinning equipment 1. Pulling the pull plate 603 to both sides, the connecting rod 602 drives the fixing head 601 to slide along the inner wall surface of the slide groove 606. At the same time, the telescopic rod 604 extends and retracts, and the second spring 605 deforms, thereby releasing the limiting effect of the fixing mechanism 6 on the lower baffle 7. After the lower baffle 7 slides down, it can move the pushing mechanism 9, making the emergency stop of the air-jet spinning equipment 1 controllable and the operation more convenient.

[0031] like Figure 4 As shown, the fixing head 601 has a U-shaped structure.

[0032] Specifically, the U-shaped fixing head 601 allows the lower baffle 7 to be located in the middle of the fixing head 601, and the fixing head 601 can support the limiting plate 8 on the surface of the lower baffle 7, preventing the lower baffle 7 from falling due to gravity, thus fixing and limiting the lower baffle 7, which is beneficial to the stability of the overall structure.

[0033] like Figures 1 to 2 As shown, the pushing mechanism 9 includes a push rod 901, which is slidably mounted on the right side of the anti-collision housing 3. A push head 902 is fixedly mounted on the right side surface of the push rod 901, and a connecting plate 903 is fixedly mounted on the left side surface of the push rod 901. An upper protrusion 904 and a lower protrusion 905 are fixedly mounted on the left side surface of the connecting plate 903, with the upper protrusion 904 located above the lower protrusion 905.

[0034] Specifically, after the lower baffle 7 removes its obstruction of the pushing mechanism 9, the operator holds the push head 902 and applies pressure to the push rod 901 to the left, pushing the push rod 901 to slide along the surface of the anti-collision housing 3, thereby causing the upper protrusion 904 and the lower protrusion 905 to contact the push plate 505 and the emergency stop button 2 respectively, thus enabling the air-jet spinning equipment 1 to be stopped urgently. After releasing the push head 902, the push plate 505 can push the upper protrusion 904 and the lower protrusion 905 back to their original positions. After triggering the emergency stop effect, the lower protrusion 905 quickly separates from the emergency stop button 2, which helps to reduce the risk of equipment failure.

[0035] like Figures 1 to 2 As shown, the surface of the pusher head 902 is provided with rubber strips, which are evenly distributed around the surface of the pusher head 902.

[0036] Specifically, the surface of the push head 902 is provided with rubber strips to increase the friction between the operator and the push head 902, making it easier and more convenient to push the push rod 901.

[0037] In summary: When an emergency stop is required for the air-jet spinning equipment 1, the fixing mechanism 6 is pulled to both sides to release the fixing of the lower baffle 7. At this time, the lower baffle 7 slides down the inner wall surface of the channel 10 under the action of gravity. The setting of the limiting plate 8 prevents the lower baffle 7 from slipping off the surface of the channel 10. Pushing the pushing mechanism 9 to the left applies pressure to the emergency stop button 2 and the automatic reset mechanism 5. The emergency stop button 2 is opened under the action of the pushing mechanism 9. Then, the pushing mechanism 9 is released. Under the action of the elastic force inside the automatic reset mechanism 5, the pushing mechanism 9 returns to its original position. After the emergency stop effect is triggered, the pushing mechanism 9 can quickly separate from the emergency stop button 2. Pulling the fixing mechanism 6 pushes the lower baffle 7 upward. When the limiting plate 8 is above the fixing mechanism 6, the fixing mechanism 6 is released. The lower baffle 7 can be fixed by limiting the limiting plate 8, thereby achieving the anti-collision effect of the air-jet spinning equipment 1. It is less likely to cause problems such as overheating, adhesion or damage of the contact points, reducing the risk of equipment failure and helping to reduce maintenance costs.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
