[0002] Rotor spinning machines are devices that operate continuously, 24 hours a day, and their opening, closing, and locking mechanisms serve the entire lifespan of the equipment. Existing spinning machines have only a single opening, closing, and locking function, requiring manual intervention for both opening and closing. This can easily lead to impact damage during the locking process, and they lack the functionality required for automatic yarn splicing. Therefore, a new solution is needed to address these issues. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a spinning device opening and closing structure suitable for automatic joint type rotor spinning machines.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A spinning device opening and closing structure suitable for an automatic joint-type rotor spinning machine includes a spinning device and an opening and closing cylinder base. A fixed base is mounted on the spinning device. A pressure plate and a locking leaf spring are mounted from top to bottom on one end of the fixed base. A locking pin is rotatably connected to the end of the locking leaf spring, and a locking roller is mounted on the locking pin. An opening and closing cylinder is hinged to the opening and closing cylinder base. A latch is slidably connected to the upper surface of the opening and closing cylinder base. A locking groove for accommodating the locking roller is formed on the upper surface of the latch. The end of the latch is installed at the output end of the opening and closing cylinder. The locking roller is located within the locking groove, and its outer surface continuously abuts against the locking groove under the action of the locking leaf spring. The opening and closing cylinder drives the latch to move, causing the locking leaf spring to deform, and uses the locking leaf spring to drive the spinning device to open and close.

[0006] Furthermore, the locking leaf spring includes a horizontal portion and an upwardly protruding arc-shaped portion connected to the horizontal portion. The horizontal portion abuts against one end of the contact fixing seat, the arc-shaped portion is located outside the fixing seat, and the end of the arc-shaped portion has a notch for accommodating the locking roller.

[0007] Furthermore, the pressure plate abuts against the horizontal portion of the locking leaf spring, and the end of the pressure plate extends and continuously abuts against the connection between the horizontal portion and the arc-shaped portion.

[0008] Furthermore, the locking groove includes an arc-shaped bottom wall, a vertically arranged first groove wall, and a second groove wall that slopes outward and downward. The two ends of the bottom wall are respectively connected to the first groove wall and the second groove wall, and the outer surface of the locking roller simultaneously abuts against the bottom wall, the first groove wall, and the second groove wall.

[0009] Furthermore, the latch has an inclined surface at the position corresponding to the second groove wall, and the inclined surface is connected to the second groove wall to form an inverted V structure.

[0010] Furthermore, an adjusting seat is installed on the side of the opening and closing cylinder seat opposite to the latch, and an adjusting bolt for limiting the latch is threaded onto the adjusting seat.

[0011] Furthermore, the latch is provided with a slider, and the upper surface of the opening and closing cylinder seat is provided with a sliding groove that matches the slider. The latch is slidably connected to the opening and closing cylinder seat through the sliding cooperation of the slider and the sliding groove.

[0012] Furthermore, the output end of the opening and closing cylinder is provided with a mounting pin, and the two ends of the mounting pin are respectively installed with snap rings after passing through the locking end.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model utilizes an automatic opening and closing spinning device with an opening and closing cylinder, which can be combined with other automatic splicing components to complete the automatic splicing of rotor spinning machines, thereby improving the automation level of the equipment and reducing labor costs.

[0015] 2. In this utility model, by cooperating with the locking groove and the locking leaf spring, on the one hand, the locking roller is continuously limited in the locking groove and keeps in contact with the locking groove; on the other hand, the spinning machine opens and closes slowly, preventing the spinning machine from opening and closing suddenly and causing other parts to be impacted and deformed, thus improving the service life of the equipment. At the same time, the locking method of the spinning machine and the rotor is changed to a flexible method, avoiding excessive locking amount.

[0016] 3. In this utility model, the lock and locking spring combination can ensure that the spinning machine can automatically open and close slightly when the yarn is spliced, and can also be fully opened manually during maintenance. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: A spinning device opening and closing structure suitable for an automatic joint-type rotor spinning machine, such as... Figures 1-6 As shown, it includes a spinning device 1 and an opening / closing cylinder seat 8. The spinning device 1 is mounted on a spinning device mounting shaft 15 and has 90° rotational freedom. The spinning device mounting shaft 15 is mounted on a main beam 14. The opening / closing cylinder seat 8 is fixed to the main beam 14 by bolts.

[0026] Furthermore, such as Figure 1 and Figure 2 As shown, a fixed base 2 is installed on the spinning machine 1. The fixed base 2 has a Z-shaped structure and is fixed to the spinning machine 1 by bolts. A pressure plate 3 and a locking leaf spring 4 are installed on one end of the fixed base 2 by bolts. The pressure plate 3 is located above the locking leaf spring 4, and the lower surface of the pressure plate 3 abuts against the locking leaf spring 4. The locking leaf spring 4 is located above one end of the fixed base 2, and the lower surface of the locking leaf spring 4 abuts against one end of the fixed base 2. A locking pin 5 is rotatably connected to the end of the locking leaf spring 4. A locking roller 6 is installed on the locking pin 5, and the locking roller 6 can rotate on the locking leaf spring 4 around the locking pin 5.

[0027] Furthermore, such as Figures 3-5As shown, the opening and closing cylinder seat 8 has a cavity for installing the opening and closing cylinder 7. The opening and closing cylinder 7 is located in the cavity of the opening and closing cylinder seat 8 and is hinged to the opening and closing cylinder seat 8. That is, the end of the opening and closing cylinder 7 is provided with a mounting pin 12. The two ends of the mounting pin 12 pass through the two sides of the opening and closing cylinder seat 8 respectively and are fitted with snap rings 13. The snap rings 13 limit the two ends of the mounting pin 12.

[0028] A latch 9 is slidably connected to the upper surface of the opening and closing cylinder seat 8. The upper surface of the latch 9 is provided with a locking groove 91 for accommodating the locking roller 6. The end of the latch 9 is installed at the output end of the opening and closing cylinder 7. That is, the opening and closing cylinder 7 drives the latch 9 to slide on the upper surface of the opening and closing cylinder seat 8, so that the locking roller 6 located in the locking groove 91 of the latch 9 moves away from or closer to the fixed seat 2.

[0029] The locking roller 6 is adapted to the locking groove 91. When the locking roller 6 is located in the locking groove 91, the outer surface of the locking roller 6 abuts against the locking groove 91. Under the normal small-amplitude opening and closing state of the spinning machine 1, the outer surface of the locking roller 6 continuously abuts against the locking groove 91 under the action of the locking leaf spring 4.

[0030] When using, such as Figure 6 As shown, during the spinning stage, the output end of the opening and closing cylinder 7 retracts and drives the locking buckle 9 to move to the left. Since the locking roller 6 is limited in the locking groove 91, the locking roller 6 moves to the left with the locking buckle 9 and pulls the fixed seat 2 to the left through the locking leaf spring 4. Since the fixed seat 2 and the spinning machine 1 are fixedly connected, the spinning machine 1 moves to the left with the fixed seat 2 until the spinning machine 1 abuts and seals the rotor, realizing the automatic closing of the spinning machine 1.

[0031] When the yarn is spliced ​​or during maintenance, the output end of the opening and closing cylinder 7 extends and drives the locking buckle 9 to move to the right. Since the locking roller 6 is limited in the locking groove 91, the locking roller 6 moves to the right with the locking buckle 9 and pushes the fixed seat 2 to the right through the locking leaf spring 4. Since the fixed seat 2 and the spinning machine 1 are fixedly connected, the spinning machine 1 moves to the right with the fixed seat 2, so that the spinning machine 1 and the rotor are separated, realizing the automatic opening of the spinning machine 1. At this time, the rotor stops rotating, so as to clean the remaining fibers in the rotor condensation tank and the dust in the cup.

[0032] Furthermore, such as Figure 2 As shown, the locking leaf spring 4 includes a horizontal part 41 and an arc-shaped part 42 that is connected to the horizontal part 41 and protrudes upward. The horizontal part 41 is located at one end of the fixed seat 2 and abuts against one end of the fixed seat 2. The arc-shaped part 42 is located outside the fixed seat 2, and the end of the arc-shaped part 42 is provided with a notch 43 for accommodating the locking roller 6.

[0033] The horizontal part 41 is the fixed end, which is fixed to the fixed base 2 by the continuous force applied by the bolts and the pressure plate 3, so that the horizontal part 41 and the fixed base 2 form a whole, thereby facilitating the movement of the spinning machine 1; the arc-shaped part 42 is the force-receiving end, which uses its deformation to drive the fixed base 2 to move, and at the same time, its upward convex setting continuously restricts the locking roller 6 within the locking groove 91; specifically:

[0034] When the spinning machine 1 closes automatically, the arc-shaped part 42 acts as a buffer, causing the spinning machine 1 to close slowly. This prevents other parts from being impacted and deformed due to sudden closing of the spinning machine 1, thus extending the service life of the equipment. The locking method of the spinning machine 1 and the rotor is changed to a flexible method, avoiding excessive locking. At the same time, under the elastic force of the arc-shaped part 42, the locking roller 6 is continuously limited within the locking groove 91 and maintains contact with the locking groove 91.

[0035] When the spinning machine 1 opens automatically, the arc-shaped part 42 acts as a buffer, allowing the spinning machine 1 to open slowly and preventing other parts from being impacted and deformed due to the instantaneous closing of the spinning machine 1, thus extending the service life of the equipment. At the same time, under the elastic force of the arc-shaped part 42, the locking roller 6 is continuously limited within the locking groove 91 and maintains contact with the locking groove 91.

[0036] Furthermore, such as Figure 2 As shown, the pressure plate 3 abuts against the horizontal portion 41 of the locking leaf spring 4. The end of the pressure plate 3 extends to the connection between the horizontal portion 41 and the arc-shaped portion 42, and under the force of the bolt, it continuously abuts against the connection between the horizontal portion 41 and the arc-shaped portion 42. With the above structure, the pressure plate 3 continuously acts on the locking leaf spring 4 to prevent the locking leaf spring 4 from disengaging from the fixed seat 2. At the same time, the auxiliary arc-shaped portion 42 limits the locking roller 6 within the locking groove 91, maintaining its contact with the locking groove 91.

[0037] Furthermore, such as Figures 3-5As shown, the locking groove 91 includes an arc-shaped bottom wall 911, a vertically arranged first groove wall 912, and a second groove wall 913 that slopes outward and downward. The two ends of the bottom of the groove are connected to the first groove wall 912 and the second groove wall 913, respectively. The outer surface of the locking roller 6 simultaneously abuts against the bottom wall 911, the first groove wall 912, and the second groove wall 913. During the opening and closing of the spinning machine 1, the first groove wall 912 and the second groove wall 913 cooperate to drive the locking roller 6 to move with the latch 9. The arc-shaped bottom wall 911 increases the contact area with the locking roller 6 and improves the driving effect. By tilting the second groove wall 913, the locking roller 6 can be easily placed into and removed from the locking groove 91. That is, when maintenance is required, the locking roller 6 and the latch 9 can be separated by external force, and the spinning machine 1 can be fully opened. It should be noted that the inclination angle of the second groove wall 913 should not be too large, so as to prevent the locking roller 6 from disengaging from the locking groove 91 during the opening and closing of the spinning machine 1.

[0038] Preferably, the latch 9 is provided with an inclined surface 92 at the position corresponding to the second groove wall 913. The inclined surface 92 is connected to the second groove wall 913 and is combined to form an inverted V structure. By providing the inclined surface 92, the locking roller 6 can be deformed and restored immediately after being disengaged from the locking groove 91.

[0039] Furthermore, an adjusting seat 10 is installed on the side of the opening and closing cylinder 7 opposite to the locking buckle 9, and an adjusting bolt 11 for limiting the locking buckle 9 is threaded onto the adjusting seat 10. By changing the position of the threaded connection between the adjusting bolt 11 and the adjusting seat 10, the sliding stroke of the locking buckle 9 is adjusted, thereby adjusting the opening and closing amplitude of the spinning machine 1.

[0040] Preferably, the adjusting bolt 11 is threadedly connected to a nut 16, which abuts against the adjusting seat 10. The nut 16 is used to limit the position of the threaded connection between the adjusting bolt 11 and the adjusting seat 10.

[0041] Furthermore, such as Figure 3 As shown, the latch 9 is equipped with a slider 93, which is integrally connected to the latch 9. The upper surface of the opening / closing cylinder 7 seat has a groove 81 that matches the slider 93. The latch 9 is slidably connected to the opening / closing cylinder 7 seat through the sliding engagement of the slider 93 and the groove 81. The engagement of the slider 93 and the groove 81 guides the movement of the latch 9 and provides support for the opening / closing cylinder 7, preventing it from disengaging from the opening / closing cylinder seat 8.

[0042] As a preferred option, the latch 9 is made of self-lubricating plastic material to reduce the coefficient of friction and ensure the sensitivity of the action and the service life.

[0043] Furthermore, a mounting pin 12 is provided through the output end of the opening and closing cylinder 7. Both ends of the mounting pin 12 pass through the ends of the latch 9 and are respectively fitted with snap rings 13, which limit the two ends of the mounting pin 12.

[0044] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
