Description

Technical Field

[0001] The present invention relates to the technical field of covers, and in particular to a cup cover structure for a dyeing cup. Background Art

[0002] Existing dyeing machines are equipped with multiple dyeing cups, each with a threaded connection between the cup body and lid. Each cup is filled with dye and the yarn to be dyed, then the lid is tightened and placed in thermal oil for heating and dyeing. During this heating process, the cup temperature can reach 80°C. Once dyeing is complete, the lid must be quickly unscrewed to remove the dyed yarn. However, due to the high temperature and the need to twist the threads, the lid opening process is continuous, causing the operator to come into contact with the cup for a period of time. Prolonged contact can easily cause burns, compromising safety. However, unscrewing the lid after cooling can compromise dyeing quality. Summary of the Invention

[0021] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0022] Example: Please refer to Figures 1-4 , a cup cover structure for a dyeing cup, comprising a cover body 4 that cooperates with a cup body 10, a lifting rod 1 and a movable plate 12 that is slidably connected to the cover body 4 and can penetrate the side wall of the cover body 4, a guide plate 11 is fixed to the bottom of the lifting rod 1, and the end of the lifting rod 1 penetrates the cover body 4, one end of the movable plate 12 cooperates with a guide groove 9 in the guide plate 11, and the guide groove 9 is arranged obliquely relative to the central axis of the lifting rod 1, and the guide groove 9 converts the vertical movement of the lifting rod 1 into the lateral movement of the movable plate 12, and the movable plate 12 can be inserted into the limiting groove of the cup body 10 under the action of the lifting rod 1, and the limiting groove is located at the cup mouth of the cup body 10. When the cup body 10 and the cover body 4 are in a locked state, The movable plates 12 on both sides are in a horizontal state, and one end of the movable plate 12 is stuck in the limit groove, so that the cover body 4 is tightly locked and fixed at the opening of the cup body 10, thereby realizing the sealing and fixation of the dyeing cup; when the dyeing cup needs to be opened, it is only necessary to lift the lifting rod 1, and the guide plate 11 will move upward, thereby driving the movable plate 12 to retract into the cover body 4, and then the cover body 4 can be taken out; therefore, the present invention only needs to lift the lifting rod 1 to realize the lifting of the cover body 4, which greatly reduces the contact time and contact area between the worker and the cover body 4, and eliminates the problem that the cup body 10 and the cover body 4 are threadedly connected, and the operator needs to twist the thread, which causes the contact time to be too long and easy to be burned.

[0023] A limit platform 3 is provided on the lifting rod 1, and a guide plate 11 is fixed to the bottom of the limit platform 3. The limit platform 3 is slidably connected to the sliding cavity 13 inside the cover body 4, which is conducive to the stable movement of the lifting rod 1; the interior of the cover body 4 is also provided with a positioning cavity 14 connected to the sliding cavity 13, and the end of the lifting rod 1 passes through the top of the positioning cavity 14. A spring 2 is sleeved on the lifting rod 1, one end of the spring 2 is located inside the positioning cavity 14 and abuts against the top of the positioning cavity 14, and the other end of the spring 2 is in contact with the limit The platform 3 abuts, and the guide plate 11 abuts against the bottom of the sliding cavity 13 under the action of the spring 2. Therefore, when the cover body 4 needs to be locked again, the cover body 4 is put back into the open end of the cup body 10. Under the action of the spring 2, the lifting rod 1 falls back, causing the guide plate 11 to move downward, thereby inserting the movable plate 12 into the limiting groove to achieve the locking of the cover body 4; and the spring 2 is also beneficial to prevent the cup body 10 from continuously applying pressure to the guide plate 11 during the rotation process, thereby ensuring the stability of the cooperation between the movable plate 12 and the limiting groove.

[0024] In this embodiment, the guide groove 9 includes a first straight groove 7, an oblique groove 6 and a second straight groove 8 connected in sequence. The central axis of the first straight groove 7 or the second straight groove 8 is parallel to the central axis of the lifting rod 1. The movable plate 12 is provided with a movable column 16 for sliding on the first straight groove 7, the oblique groove 6 and the second straight groove 8. The oblique groove 6 can realize the conversion of the vertical movement of the lifting rod 1 into the lateral movement of the movable plate 12.

[0025] It is worth mentioning that the diameter of the movable column 16 is equal to the width of the first straight groove 7 or the second straight groove 8, and the ratio of the height to the width of the first straight groove 7 or the second straight groove 8 is greater than 1 and less than 1.5. When the guide plate 11 abuts against the bottom of the sliding cavity 13, the movable column 16 abuts against the top of the first straight groove 7. When the limit platform 3 abuts against the top of the sliding cavity 13, the movable column 16 abuts against the bottom of the second straight groove 8.

[0026] After testing and verification, when the ratio of the height dimension to the width dimension of the first straight slot 7 or the second straight slot 8 is less than 1, taking the first straight slot 7 as an example; first, a part of the movable column 16 will be exposed in the inclined slot 6 and not completely located inside the first straight slot 7. At this time, the horizontal limiting ability of the guide plate 11 on the movable plate 12 is poor, and the movable plate 12 will slip when subjected to external force (such as the centrifugal force generated when the cup body 10 rotates; the cup body 10 will be installed in the circumferential side wall of the rotating cage and heated in the rotating cage after the cup cover is installed), making the cover body 4 unstable; second, the spring 2 will undergo permanent elastic deformation after permanent deformation, which will further reduce the horizontal limiting ability of the guide plate 11 on the movable plate 12, thereby reducing the service life of the spring 2; third, under the action of the internal pressure of the cup body 10, The movable plate 12 will produce a certain amount of squeezing on the limiting groove. At this time, since a part of the movable column 16 will be exposed in the inclined groove 6, it is necessary to overcome the maximum static friction between the movable plate 12 and the limiting groove. Since the maximum static friction is greater than the sliding friction, and the force on the lifting rod 1 is gradually increasing, in a short period of time, the horizontal component of the inclined groove 6 on the movable column 16 is the same as the vertical component, and increases synchronously. In addition, there is a certain pressure inside the cup body 10, so the maximum static friction will also increase synchronously at this time, so it will get stuck or a large lifting force will be required in a short time, which makes it inconvenient to remove the cover body 4; the relationship between the second straight groove 8 and the movable column 16 is similar to that between the first straight groove 7 and the movable column 16, so I will not go into too much detail here;

[0027] When the ratio of the height dimension to the width dimension of the first straight groove 7 or the second straight groove 8 reaches between 1 and 1.5, taking the first straight groove 7 as an example; first, the end of the movable column 16 will be completely located inside the first straight groove 7. At this time, the guide plate 11 has a strong ability to limit the horizontal direction of the movable plate 12. When the movable plate 12 is subjected to external force (such as the centrifugal force generated when the cup body 10 rotates), it will not slip under the limit of the side wall of the first straight groove 7, thereby making the cover body 4 more secure; second, because the end of the movable column 16 is completely located inside the inclined groove 6, the lifting rod 1 overcomes the spring 2 at this time. The force works for a period of time; when the movable column 16 enters the inclined slot 6, the inclined slot 6 has a certain kinetic energy. When the inclined slot 6 hits the movable column 16, the movable column 16 has a slight collision. At this time, the movable plate 12 will tremble slightly. During this process, there will be a small gap between the movable plate 12 and the limit groove. At this time, the theoretical maximum static friction force of the movable plate 12 is instantly reduced, thereby facilitating the lateral movement of the movable plate 12. The relationship between the second straight slot 8 and the movable column 16 is similar to the relationship between the first straight slot 7 and the movable column 16, so I will not go into too much detail here.

[0028] When the ratio of the height dimension to the width dimension of the first straight groove 7 or the second straight groove 8 is greater than 1.5, taking the first straight groove 7 as an example; firstly, the overly long first straight groove 7 easily causes the inclined groove 6 to hit the movable column 16. Due to the excessive kinetic energy of the inclined groove 6, it is easy to bend the movable plate 12, thereby reducing the service life of the movable plate 12. Secondly, the size of the guide plate 11 is increased, thereby increasing the overall size of the cover body 4.

[0029] In this embodiment, when the ratio of the height dimension to the width dimension of the first straight groove 7 or the second straight groove 8 is adjusted to 1.25, it can ensure that the movable plate 12 slides smoothly into the inclined groove 6 and ensures stable lateral movement of the movable plate 12.

[0030] In other embodiments, the angle between the central axis of the inclined slot 6 and the central axis of the lifting rod 1 is ∈ (25°, 59°); where the material of the movable plate 12 and the cover 4 is stainless steel, the friction coefficient between the movable plate 12 and the limit groove is 0.30~0.40 (without lubrication), and the maximum friction coefficient is 0.4; when the pressure of the internal pressure on the cover 4 is not considered, the condition when the movable plate 12 slides is, Fcos >0.4Fsin , take the correction coefficient as 1.5 (considering the maximum static friction and the pressure generated by the internal pressure on the cover 4), so at this time, Fcos >0.4×1.5Fsin Where F is the force exerted by the chute 6 on the movable column 16; the solution is <59.04°; therefore, when When the angle is less than 59.04°, the movable plate 12 will not self-lock;

[0031] And when When the angle is less than 25°, although self-locking will not occur, the travel ratio of the guide plate 11 and the movable plate 12 will increase; thereby, the height of the guide plate 11 will increase, thereby increasing the height of the cover body 4;

[0032] In this embodiment, When the angle is adjusted to 35°, it can ensure that the guide plate 11 does not self-lock and that the lateral movement of the movable plate 12 can be achieved without the guide plate 11 moving a large distance.

[0033] In other embodiments, a sealing ring 5 is embedded in the lower part of the cover body 4, and the sealing ring 5 is located below the movable plate 12; a thermal insulation layer is sprayed on the cover body 4 below the sealing ring 5, which not only plays a sealing role, but also helps to insulate heat and prevent the temperature from being transmitted to the lifting rod 1 and scalding the staff; a chamfer is provided on the cover body 4 below the sealing ring 5, and the angle β∈ (10°, 25°) between the chamfer and the side wall of the cup body 10 is conducive to the uniform deformation of the sealing ring 5 in the sealing groove, thereby improving the sealing effect.

[0034] In other embodiments, a Z-shaped groove 20 is provided on the side wall of the sliding cavity 13, and a positioning rod is rotatably connected to the lifting rod 1. The bottom of the positioning rod is fixedly connected to the limiting rod, and a cavity is provided on the limiting platform 3 to facilitate the rotation of the limiting rod. The end of the limiting rod passing through the limiting platform 3 can slide on the Z-shaped groove 20, and a notch is provided on the limiting platform 3 for the rotation of the limiting rod. When the limiting rod is rotated to the two transverse grooves of the Z-shaped groove 20, the lifting rod 1 will not move in the axial direction, thereby facilitating installation while ensuring the stability of the cooperation between the movable plate 12 and the limiting groove; and a permanent magnet is provided at the end of the transverse groove to attract the limiting rod to ensure the stability of the limiting rod on the transverse groove.

[0035] In other embodiments, a slot 15 is provided on the lifting rod 1, and a robotic arm 19 takes the cover body 4 out of the cup body 10 through the slot 15, wherein the robotic arm 19 is provided with a horizontal clamp 17 and a vertical clamp 18 for clamping the slot 15, and when the horizontal clamp 17 abuts against the top of the cover body 4, the vertical clamp 18 clamps the slot 15, and then the vertical clamp 18 moves upward, thereby realizing the removal of the movable plate 12, and then the horizontal clamp 17 and the vertical clamp 18 rise synchronously, thereby realizing the separation of the cover body 4 and the cup body 10, and the robotic arm 19 replaces manual operation to avoid burns to the operator.
