Description

Technical Field

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

[0002] Multiple dyeing cups are installed on existing dyeing machines. The cup body and the cup cover of the dyeing cup are connected by threads. Each dyeing cup is filled with dye and yarn to be dyed, and then the cup cover is tightened and placed in heat-conducting oil for heating and dyeing. During this heating process, the temperature of the dyeing cup can reach 80°C. After dyeing is completed, it is necessary to quickly unscrew the cup cover manually to take out the dyed yarn. However, due to the high temperature of the dyeing cup and the need to turn the threads, the process of opening the cover is a continuous process, which makes the operator contact the dyeing cup for a period of time. If the contact time is too long, it is easy to scald the operator, and the safety is low. But if it is unscrewed after cooling, it will affect the dyeing quality. Summary of the Invention

[0003] The purpose of the present invention is to design a cover structure for a dyeing cup to solve the problems raised in the background art. To achieve the above purpose, the present invention provides the following technical solutions: It includes a cover body that cooperates with the cup body. A lifting rod is slidably connected to the cover body, and a movable plate that can penetrate the side wall of the cover body is slidably connected. A guide plate is fixedly connected to the bottom of the lifting rod, and the end of the lifting rod penetrates the cover body. One end of the movable plate cooperates with the guide groove in the guide plate. The guide groove is arranged obliquely relative to the central axis of the lifting rod. The guide groove converts the vertical movement of the lifting rod into the lateral movement of the movable plate. The movable plate can be inserted into the limiting groove of the cup body under the action of the lifting rod. The limiting groove is located at the cup mouth of the cup body.

[0004] Further, a limiting platform is provided on the lifting rod. The guide plate is fixedly connected to the bottom of the limiting platform. The limiting platform is slidably connected to the sliding cavity inside the cover body.

[0005] Further, a positioning cavity communicating with the sliding cavity is also provided inside the cover body. The end of the lifting rod penetrates the top of the positioning cavity. A spring is sleeved on the lifting rod. One end of the spring is located inside the positioning cavity and abuts against the top of the positioning cavity. The other end of the spring abuts against the limiting platform. The guide plate abuts against the bottom of the sliding cavity under the action of the spring.

[0006] Further, the guide groove includes a first straight groove, an inclined groove, and a second straight groove that are connected in sequence. The central axes of the first straight groove and the second straight groove are both parallel to the central axis of the lifting column. An activity column for sliding on the first straight groove, the inclined groove, and the second straight groove is provided in the movable plate.

[0007] Further, the diameter of the movable column is equal to the width dimensions of the first straight groove and the second straight groove, and the ratio of the height dimension to the width dimension of the first straight groove and the second straight groove is greater than 1 and less than 1.5. When the guiding plate abuts against the bottom of the sliding cavity, the movable column abuts against the top of the first straight groove. When the limiting platform abuts against the top of the sliding cavity, the movable column abuts against the bottom of the second straight groove.

[0008] Further, the included angle ɑ between the central axis of the inclined groove and the central axis of the lifting pull rod is in the range of (25°, 59°).

[0009] Further, a sealing ring is embedded in the lower part of the cover body, and the sealing ring is located below the movable plate.

[0010] Further, a heat insulation layer is sprayed on the cover body below the sealing ring.

[0011] Further, a chamfer is provided on the cover body below the sealing ring, and the included angle β between the chamfer and the side wall of the cup body is in the range of (10°, 25°).

[0012] Further, a Z-shaped groove is provided on the side wall of the sliding cavity. A positioning rod is rotatably connected to the lifting pull rod. The bottom of the positioning rod is fixedly connected with a limiting rod. The end of the limiting rod passing through the limiting platform can slide on the Z-shaped groove, and a notch for the rotation of the limiting rod is provided on the limiting platform.

[0013] Further, a notch is provided on the lifting pull rod, and the manipulator takes out the cover body from the cup body through the notch.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention is provided with a lifting pull rod and a movable plate, and the guiding plate converts the vertical movement of the lifting pull rod into the horizontal movement of the movable plate. Therefore, when the dyeing cup needs to be opened, only the lifting pull rod needs to be lifted, and the guiding plate moves upward accordingly, thereby driving the movable plate to retract into the cover body, and then the cover body can be taken out. Therefore, the present invention greatly reduces the contact time and contact area between the worker and the cover body, and eliminates the problem that the contact time is too long and easy to scald due to the threaded connection between the cup body and the cover body, which requires the operator to turn the thread.

Specific embodiments

[0021] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in combination with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features and their effects of the present invention as follows.

[0022] Embodiment: Please refer to Figures 1-4 , a cup cover structure for a dyeing cup, comprising a cover body 4 cooperating with the cup body 10, a lifting rod 1 is slidably connected to the cover body 4 and a movable plate 12 that can penetrate the side wall of the cover body 4 is slidably connected, a guiding plate 11 is fixedly connected 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 the guiding groove 9 in the guiding plate 11. The guiding groove 9 is arranged obliquely relative to the central axis of the lifting rod 1. The guiding groove 9 converts the vertical movement of the lifting rod 1 into the lateral movement of the movable plate 12. The movable plate 12 can be inserted into the limiting groove of the cup body 10 under the action of the lifting rod 1. 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 clamped into the limiting 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 fixing of the dyeing cup; when the dyeing cup needs to be opened, only the lifting rod 1 needs to be lifted, and the guiding plate 11 moves upward accordingly, 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 lift the cover body 4, greatly reducing the contact time and contact area between the worker and the cover body 4, and eliminating the problem that in the past, due to the threaded connection between the cup body 10 and the cover body 4, the operator needed to twist the thread, resulting in too long contact time and easy scalding.

[0023] The lifting rod 1 is provided with a limiting platform 3, and a guiding plate 11 is fixedly connected to the bottom of the limiting platform 3. The limiting platform 3 is slidably connected to a sliding cavity 13 inside the cover body 4, which is beneficial to the stable movement of the lifting rod 1. Inside the cover body 4, there is also a positioning cavity 14 communicating with the sliding cavity 13. The end of the lifting rod 1 penetrates 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 abuts against the limiting platform 3. Under the action of the spring 2, the guiding plate 11 abuts against the bottom of the sliding cavity 13. Therefore, when the cover body 4 needs to be relocked, the cover body 4 is placed back into the opening end of the cup body 10. Under the action of the spring 2, the lifting rod 1 falls back, causing the guiding plate 11 to move downward, so that the movable plate 12 is inserted into the limiting groove, realizing the relocking of the cover body 4. The spring 2 also helps to prevent the cup body 10 from continuously pressing on the guiding plate 11 during the rotation process, ensuring the stable cooperation between the movable plate 12 and the limiting groove.

[0024] In this embodiment, the guiding groove 9 includes a first straight groove 7, an inclined groove 6, and a second straight groove 8 that are connected in sequence. The central axes of the first straight groove 7 or the second straight groove 8 are parallel to the central axis of the lifting column. An active column 16 for sliding on the first straight groove 7, the inclined groove 6, and the second straight groove 8 is provided in the movable plate 12. The inclined groove 6 can convert 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 active column 16 is equal to the width dimension of the first straight groove 7 or the second straight groove 8, and 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 and less than 1.5. When the guiding plate 11 abuts against the bottom of the sliding cavity 13, the active column 16 abuts against the top of the first straight groove 7. When the limiting platform 3 abuts against the top of the sliding cavity 13, the active column 16 abuts against the bottom of the second straight groove 8.

[0026] After experimental verification, when the ratio of the height dimension to the width dimension of the first straight groove 7 or the second straight groove 8 is less than 1, taking the first straight groove 7 as an example: First, a part of the movable column 16 will be exposed in the inclined groove 6 and is not completely located inside the first straight groove 7. At this time, the guiding plate 11 has a poor horizontal limiting ability for the movable plate 12. When the movable plate 12 is subjected to an external force (such as the centrifugal force generated when the cup body 10 rotates; the cup body 10 will rotate in the circumferential side wall of the rotating cage after installing the cup lid and is heated in the rotating cage), it will slip, making the lid body 4 not firm. Second, after the spring 2 is permanently deformed, it will undergo permanent elastic deformation. At this time, it will further reduce the horizontal limiting ability of the guiding plate 11 for 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 exert a certain extrusion on the limiting groove. At this time, since a part of the movable column 16 is exposed in the inclined groove 6, it is necessary to overcome the maximum static friction force between the movable plate 12 and the limiting groove. Since the maximum static friction force is greater than the sliding friction force and the force on the lifting rod 1 gradually increases, at this time, in a short period of time, the horizontal component force and the vertical component force of the inclined groove 6 on the movable column 16 in the horizontal direction are the same and increase synchronously. Coupled with the certain pressure inside the cup body 10, the maximum static friction force will also increase synchronously at this time. Therefore, jamming will occur or a large lifting force will be required in a short period of time, making it inconvenient to remove the lid body 4. The relationship between the second straight groove 8 and the movable column 16 is similar to the relationship between the first straight groove 7 and the movable column 16, and no more details will be elaborated 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 guiding plate 11 has a strong horizontal limiting ability for the movable plate 12. When the movable plate 12 is subjected to an external force (such as the centrifugal force generated when the cup body 10 rotates), it will not slip under the limitation of the side wall of the first straight groove 7, making the lid body 4 more firm. Second, since the end of the movable column 16 is completely located inside the inclined groove 6, at this time, the lifting rod 1 is lifted to overcome the elastic force of the spring 2 and do work for a period of time. Then, when the movable column 16 enters the inclined groove 6, the inclined groove 6 has a certain kinetic energy. When the inclined groove 6 hits the movable column 16, the movable column 16 undergoes a small collision. At this time, the movable plate 12 will vibrate slightly. During this process, there will be a small gap between the movable plate 12 and the limiting groove. At this time, the theoretical maximum static friction force of the movable plate 12 decreases instantaneously, facilitating the lateral movement of the movable plate 12. The relationship between the second straight groove 8 and the movable column 16 is similar to the relationship between the first straight groove 7 and the movable column 16, and no more details will be elaborated 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, when the overlong 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, thus reducing the service life of the movable plate 12. Secondly, it increases the size of the guide plate 11, 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 smoothly slides into the inclined groove 6 and ensure the stable lateral movement of the movable plate 12.

[0030] In other embodiments, the included angle ɑ between the central axis of the inclined groove 6 and the central axis of the lifting pull rod 1 is in the range of (25°, 59°); wherein, the materials of the movable plate 12 and the cover body 4 are selected as stainless steel, so the friction coefficient between the movable plate 12 and the limiting groove is 0.30 - 0.40 (without lubrication), and the maximum friction coefficient is taken as 0.4; when not considering the pressure of the internal pressure on the cover body 4, the condition for the movable plate 12 to slide is Fcosɑ > 0.4Fsinɑ. Taking the correction coefficient as 1.5 (considering the maximum static friction and the pressure generated by the internal pressure on the cover body 4), so at this time, Fcosɑ > 0.4×1.5Fsinɑ; where F is the acting force of the inclined groove 6 on the movable column 16; and it is solved that ɑ < 59.04°; therefore, when ɑ < 59.04°, the movable plate 12 will not lock itself.

[0031] When ɑ is less than 25°, although self-locking will not occur, it will increase the stroke ratio between the guide plate 11 and the movable plate 12; thus resulting in an increase in the height dimension of the guide plate 11, and consequently an increase in the height of the cover body 4.

[0032] In this embodiment, when ɑ is adjusted to 35°, it can ensure that the guide plate 11 will not lock itself and at the same time can ensure that the guide plate 11 can achieve the lateral movement of the movable plate 12 without moving a large position.

[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 heat insulation layer is sprayed on the cover body 4 below the sealing ring 5, which can play a sealing role and is conducive to heat insulation to prevent the temperature from being transmitted to the lifting pull rod 1 and scalding the staff; a chamfer is provided on the cover body 4 below the sealing ring 5, and the included angle β between the chamfer and the side wall of the cup body 10 is in the range of (10°, 25°), which is conducive to the uniform deformation of the sealing ring 5 in the sealing groove and is conducive to improving the sealing effect.

[0034] In other embodiments, a Z-shaped groove 20 is provided on the side wall of the sliding cavity 13. A positioning rod is rotatably connected to the lifting rod 1, and a limiting rod is fixedly connected to the bottom of the positioning rod. 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. A notch for the rotation of the limiting rod is provided on the limiting platform 3. When the limiting rod rotates to the two horizontal grooves of the Z-shaped groove 20, the lifting rod 1 will not move in the axial direction, which facilitates installation and at the same time ensures the stability of the cooperation between the movable plate 12 and the limiting groove. A permanent magnet is provided at the end of the horizontal groove to attract the limiting rod and ensure the stable retention of the limiting rod on the horizontal groove.

[0035] In other embodiments, a notch 15 is provided on the lifting rod 1. The robotic arm 19 takes out the cover 4 from the cup body 10 through the notch 15. Among them, the robotic arm 19 is provided with a horizontal jaw 17 and a vertical jaw 18 for clamping the notch 15. When the horizontal jaw 17 abuts against the top of the cover 4, the vertical jaw 18 clamps the notch 15, and then the vertical jaw 18 moves upward, thereby realizing the extraction of the movable plate 12. Subsequently, the horizontal jaw 17 and the vertical jaw 18 rise synchronously, thereby realizing the separation of the cover 4 from the cup body 10. By using the robotic arm 19 instead of manual operation, the operator is prevented from being scalded.
