Description

Technical Field

[0001] This application relates to the field of opening machine technology, and in particular to an opening mixer. Background Technology

[0002] Opening and mixing machines are equipment used in the textile industry to loosen and process large pieces of raw materials such as cotton and wool. They mainly consist of four parts: feeding, opening, carding, and discharging. After being processed by the opening and mixing machine, the originally tightly compressed fibers of cotton, wool, and other raw materials can be broken up and cleaned for subsequent spinning processing.

[0003] During the opening and combing process, as the negative pressure system operates, some small broken fibers may enter the air passage of the negative pressure system along with dust from the cotton and wool, and then accumulate on the filter surface, affecting the normal operation of the negative pressure system. In addition, under the effect of static electricity, some relatively large fibers may also float due to mutual attraction or repulsion, thereby increasing the probability of filter clogging.

[0004] Therefore, it is necessary to propose an opening mixer to solve the above problems. Summary of the Invention

[0005] To address the problem that during opening and carding, floating long and short fibers gradually accumulate on the filter screen surface, affecting the negative pressure system's ability to clean dust mixed in with cotton and wool, this application provides an opening and mixing machine.

[0006] This application provides an opening and mixing machine, which adopts the following technical solution: A loosening mixer includes a body, a negative pressure chamber fixedly connected to the top of the body, a fan installed at the rear of the top of the negative pressure chamber, a horizontal plate installed inside the negative pressure chamber, sliders fixedly connected to both ends of the horizontal plate, grooves opened on the front and rear sides of the top of the sliders on both sides, hollow cylinders fixedly connected to the side of the grooves on the front and rear sides, a connecting rod slidably connected inside the multiple hollow cylinders, a vertical plate fixedly connected to the side of the connecting rods on the front and rear sides, a rotating plate rotatably connected to the side of the vertical plates on the front and rear sides, and perforated plates provided on the front and rear sides above the horizontal plate, the top of the rotating plate rotatably connected to the bottom sides of the perforated plates on the front and rear sides respectively.

[0007] When the fan is working and carries away dust mixed in with cotton and wool through negative pressure, the water injected into the lower part of the negative pressure chamber and the perforated plate in contact with the water can intercept the dust and fibers in the airflow. When a lot of dust and fibers accumulate on the surface of the rear perforated plate, the horizontal plate can be moved forward. At this time, the slider connected to the horizontal plate can drive the corresponding hollow cylinder to move synchronously through each groove. Under the action of the connecting rod and the sealing ring, the air pressure inside each hollow cylinder is higher than that outside and will not leak. Therefore, when the horizontal plate and the slider move forward, the front hollow cylinder can be prevented from entering the corresponding connecting rod under the action of the initial air pressure inside. Then, the vertical plate can apply a deflecting thrust to the rotating plate, so that the perforated plate connected to the front rotating plate can move upward and leave the water until the front perforated plate contacts the top of the negative pressure chamber. At this time, as the horizontal plate and slider continue to move forward, the first connecting rod on the front side can overcome the gradually increasing air pressure inside the hollow cylinder and enter the corresponding hollow cylinder. At the same time, the air pressure inside the rear hollow cylinder can also decrease during the forward movement of the hollow cylinder and can no longer provide the thrust for the corresponding connecting rod, vertical plate, and rotating plate to lift the rear perforated plate. Therefore, when the air pressure inside the front hollow cylinder gradually increases, the first connecting rod on the rear side can stop leaving the hollow cylinder under the combined action of the air pressure inside the corresponding hollow cylinder and the gravity of the perforated plate and rotating plate. At this time, the rear perforated plate can gradually enter the water body with the deflection of the corresponding rotating plate, so as to clean the dust and fibers accumulated on its surface when the front perforated plate blocks the dust and fibers. Conversely, when the front perforated plate needs to clean the dust and fibers accumulated on its surface, the horizontal plate and slider can be moved backward. At this time, the front perforated plate can remain temporarily stationary due to the reduced air pressure inside the corresponding hollow cylinder, while the rear perforated plate can move upward in time under the action of the air pressure inside the corresponding hollow cylinder and the connecting rod, vertical plate, and rotating plate. When the rear perforated plate reaches its limit position and the air pressure inside the corresponding hollow cylinder increases, the front perforated plate can gradually move downward into the water as the front hollow cylinder and connecting rod move backward, achieving a balance with the air pressure inside the corresponding hollow cylinder. In summary, the alternating operation of the front and rear perforated plates can ensure that dust and fibers are always effectively intercepted without affecting the normal operation of the blower, avoiding the need to repeatedly stop and start the mixer to deal with the accumulated dust and fibers.

[0008] A further improvement to the technical solution of this application is that a collection chamber is fixedly connected to the top center of the horizontal plate, and guide plates are fixedly connected to the upper front and rear sides of the collection chamber.

[0009] In the above technical solution, since the top of the collection chamber is slightly higher than the water surface and the lower part of the guide plate is submerged in the water, when the collection chamber and the guide plate move back and forth with the horizontal plate, the fibers in the water can enter the collection chamber along the guide plate and be trapped inside the collection chamber, thereby achieving the purpose of collecting the fibers in the water. This prevents the perforated plate from being unable to be cleaned properly due to too many floating fibers in the water after the opening mixer has been working for a long time. Thus, without the need to replace the water, the continuous working time of the opening mixer can be further extended.

[0010] A further improvement to the technical solution of this application is that a baffle is fixedly connected to the front side of the bottom end of the fan, and an inclined plate is fixedly connected to the top of the baffle.

[0011] In the above technical solution, the baffle can prevent water in the rear area of ​​the negative pressure chamber from flowing into the machine body through the air inlet in the front area of ​​the negative pressure chamber. At the same time, when the water fluctuates significantly due to the movement of the horizontal plate, slider, etc. and collides with the baffle, the inclined plate can intercept the water splashed after the collision.

[0012] A further improvement of the technical solution of this application is that: an electric push rod is fixedly connected to the rear top of the negative pressure chamber, a connecting rod 2 is fixedly connected to the output end of the electric push rod, the front end of the connecting rod 2 passes through the negative pressure chamber and is fixedly connected to the rear side of the horizontal plate, and a frustum is fixedly connected to the front outer side of the connecting rod 2, the front end of the frustum is fixedly connected to the rear side of the horizontal plate.

[0013] In the above technical solution, the electric push rod can apply a forward and backward thrust to the connecting rod 2, thereby causing the horizontal plate, slider and other related components to move. Furthermore, the frustum can increase the contact area between the connecting rod 2 and the horizontal plate, preventing the horizontal plate from breaking due to excessive force in the contact area with the connecting rod 2.

[0014] A further improvement to the technical solution of this application is that: both the upper and lower ends of the horizontal plate are fixedly connected to reinforcing plates, and the two reinforcing plates on the opposite side are respectively fixedly connected to the upper and lower parts of the slider on the side closer to it.

[0015] By adopting the above technical solution, the contact area between the horizontal plate and the slider can be increased by the reinforcement version, thereby improving their connection strength and ensuring that the slider can always move synchronously with the horizontal plate.

[0016] A further improvement to the technical solution of this application is that: the bottom ends of both sliders are slidably connected to the bottom end of the negative pressure chamber, the bottom ends of multiple vertical plates are slidably connected to the bottom end of the groove, and the two sides of the front and rear side perforated plates are slidably connected to the two sides inside the negative pressure chamber.

[0017] Using the above technical solution, the negative pressure chamber can guide and limit the slider and the perforated plate to ensure that the slider and the perforated plate will only move along the predetermined trajectory. Similarly, the groove can guide and limit the vertical plate to prevent the vertical plate from deflecting and causing the rotating plate to be subjected to shear force.

[0018] A further improvement to the technical solution of this application is that: both sides of the collection chamber are slidably connected to limit plates, and the bottom ends of both limit plates are fixedly connected to the top of the horizontal plate.

[0019] The above technical solution uses a limiting plate to restrict the position of the collection bin, ensuring that the collection bin can always move back and forth with the horizontal plate and preventing the collection bin from tipping over and failing to function properly.

[0020] A further improvement of the technical solution of this application is that: multiple protrusions are fixedly connected to the bottom of the horizontal plate, and multiple balls are rotatably connected to the bottom of each of the multiple protrusions, and the bottom of each of the multiple balls is slidably connected to the bottom of the negative pressure chamber.

[0021] Using the above technical solution, the sharp corners of the protrusions can agitate the water at the bottom to a certain extent, thereby causing the fibers in the water to float to the surface, preventing a large number of fibers from sinking to the bottom and being unable to be collected by the collection chamber. Furthermore, the friction between the protrusions and the negative pressure chamber can be reduced by the various ball bearings.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This application provides an opening and mixing machine. By the displacement of the horizontal plate and the slider, as well as the change of air pressure inside the hollow cylinder, the connecting rod, the vertical plate, and the rotating plate can sequentially drive the perforated plates on the front and rear sides into the water to clean the fibers and dust accumulated on the surface. This effectively ensures the stable operation of the negative pressure system, thereby extending the continuous working time of the opening and mixing machine and avoiding the impact on production efficiency due to multiple shutdowns for cleaning fibers and dust.

[0023] 2. This application provides an opening mixer, which can collect fibers in water by means of a collection bin and a guide plate that move with the horizontal plate. This prevents the fibers from being deposited in the water by the perforated plate and negative pressure system after the opening mixer has been working for a long time, thus affecting the water's cleaning effect on the perforated plate. This reduces the frequency of water replacement and further extends the continuous working time of the opening mixer while saving water. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0027] Example 1 See Figures 1-4 This application provides an opening and mixing machine, including a machine body 1. A negative pressure chamber 2 is fixedly connected to the top of the machine body 1. A fan 3 is provided at the rear of the top of the negative pressure chamber 2. A horizontal plate 4 is provided inside the negative pressure chamber 2. A slider 5 is fixedly connected to both ends of the horizontal plate 4. Grooves 6 are provided on the front and rear sides of the top of the sliders 5 on both sides. Hollow cylinders 7 are fixedly connected to the side of the grooves 6 on the front and rear sides that are close to each other. A connecting rod 8 is slidably connected inside a plurality of hollow cylinders 7. A vertical plate 9 is fixedly connected to the side of the connecting rod 8 on the front and rear sides that are far apart. A rotating plate 10 is rotatably connected to the side of the vertical plate 9 on the front and rear sides that are far apart. Perforated plates 11 are provided on the front and rear sides above the horizontal plate 4. The top of the rotating plate 10 is rotatably connected to the bottom sides of the perforated plates 11 on the front and rear sides respectively. A baffle 14 is fixedly connected to the front side of the bottom end of the blower 3. An inclined plate 15 is fixedly connected to the top of the baffle 14. An electric push rod 17 is fixedly connected to the rear of the top of the negative pressure chamber 2. A connecting rod 16 is fixedly connected to the output end of the electric push rod 17. The front end of the connecting rod 16 passes through the negative pressure chamber 2 and is fixedly connected to the rear side of the horizontal plate 4. A frustum 18 is fixedly connected to the front of the outer side of the connecting rod 16. The front end of the frustum 18 is fixedly connected to the rear side of the horizontal plate 4. Reinforcing plates 19 are fixedly connected to both ends of the horizontal plate 4. The reinforcing plates 19 on both sides are fixedly connected to the upper and lower parts of the sliders 5 on the side that are close to each other. The bottom ends of the sliders 5 on both sides are slidably connected to the bottom end of the negative pressure chamber 2. The bottom ends of the multiple vertical plates 9 are slidably connected to the bottom end of the groove 6. The two sides of the perforated plates 11 on the front and rear sides are slidably connected to the two sides inside the negative pressure chamber 2.

[0028] In this embodiment, when the fan 3 is working and carries away the dust mixed in the cotton and wool through negative pressure, the water injected into the lower part of the negative pressure chamber 2 and the perforated plate 11 in contact with the water can intercept the dust and fibers in the airflow. When a lot of dust and fibers accumulate on the surface of the rear perforated plate 11, the horizontal plate 4 can be moved forward. At this time, the slider 5 connected to the horizontal plate 4 can drive the corresponding hollow cylinder 7 to move synchronously through each groove 6. Under the action of the connecting rod 8 and the sealing ring, the air pressure inside each hollow cylinder 7 is higher than that outside and will not leak. Therefore, when the horizontal plate 4 and the slider 5 move forward, the front hollow cylinder 7 can temporarily prevent the corresponding connecting rod 8 from entering the hollow cylinder 7 under the action of the initial internal air pressure. Then, the vertical plate 9 can apply a deflecting thrust to the rotating plate 10 so that the perforated plate 11 connected to the front rotating plate 10 can move upward and leave the water until the front perforated plate 11 contacts the top of the negative pressure chamber 2. At this time, as the horizontal plate 4 and the slider 5 continue to move forward, the front connecting rod 8 can overcome the gradually increasing air pressure inside the hollow cylinder 7 and enter the corresponding hollow cylinder 7. At the same time, the air pressure inside the rear hollow cylinder 7 can also decrease during the forward movement of the hollow cylinder 7 and can no longer provide the corresponding connecting rod 8, the vertical plate 9, and the rotating plate 10 with the thrust to lift the rear perforated plate 11. Therefore, when the air pressure inside the front hollow cylinder 7 gradually increases, the rear connecting rod 8 can stop leaving the hollow cylinder 7 under the combined action of the air pressure inside the corresponding hollow cylinder 7 and the gravity of the perforated plate 11 and the rotating plate 10. At this time, the rear perforated plate 11 can gradually enter the water body with the deflection of the corresponding rotating plate 10, so as to clean the dust and fibers accumulated on its surface when the front perforated plate 11 blocks the dust and fibers. Conversely, when the front side plate 11 needs to clean the dust and fibers accumulated on its surface, the horizontal plate 4 and the slider 5 can be moved backward. At this time, the front side plate 11 can remain temporarily stationary due to the reduced air pressure inside the corresponding hollow cylinder 7, while the rear side plate 11 can move upward in time under the action of the air pressure inside the corresponding hollow cylinder 7 and the connecting rod 8, the vertical plate 9, and the rotating plate 10. When the rear side plate 11 reaches its limit position and the air pressure inside the corresponding hollow cylinder 7 increases, the front side plate 11 can gradually move downward into the water as the front hollow cylinder 7 and the connecting rod 8 move backward, thus achieving a balance with the air pressure inside the corresponding hollow cylinder 7. In summary, by alternating the operation of the front and rear side plates 11, dust and fibers can always be effectively intercepted without affecting the normal operation of the blower 3, avoiding the need to repeatedly stop and open the mixer to deal with the accumulated dust and fibers. The baffle 14 prevents water in the rear region of the negative pressure chamber 2 from flowing into the machine body 1 through the air vent in the front region of the negative pressure chamber 2. Simultaneously, when the water fluctuates significantly due to the movement of the horizontal plate 4, slider 5, etc., and collides with the baffle 14, the inclined plate 15 intercepts the splashed water after the collision. The electric push rod 17 applies a forward and backward thrust to the connecting rod 16, thereby allowing the horizontal plate 4, slider 5, and other related components to move. Furthermore, the frustum 18 increases the contact area between the connecting rod 16 and the horizontal plate 4. To prevent the contact area between the horizontal plate 4 and the connecting rod 16 from breaking due to excessive force, the reinforcing plate 19 increases the contact area between the horizontal plate 4 and the slider 5, thereby improving their connection strength and ensuring that the slider 5 can always move synchronously with the horizontal plate 4. The negative pressure chamber 2 guides and limits the slider 5 and the perforated plate 11 to ensure that the slider 5 and the perforated plate 11 will only move along the predetermined trajectory. Similarly, the groove 6 guides and limits the vertical plate 9 to prevent the vertical plate 9 from deflecting and causing the rotating plate 10 to be subjected to shear force.

[0029] Example 2 See Figure 5 and Figure 6 Based on Embodiment 1, this application provides a technical solution: preferably, a collection chamber 12 is fixedly connected to the top center of the horizontal plate 4, and guide plates 13 are fixedly connected to the upper front and rear sides of the collection chamber 12. Both sides of the collection chamber 12 are slidably connected to limit plates 20. The bottom ends of the limit plates 20 on both sides are fixedly connected to the top of the horizontal plate 4. Multiple protrusions 21 are fixedly connected to the bottom of the horizontal plate 4. Multiple balls 22 are rotatably connected to the bottom of the multiple protrusions 21. The bottom of the multiple balls 22 is slidably connected to the bottom of the negative pressure chamber 2.

[0030] In this embodiment, since the top of the collection chamber 12 is slightly higher than the water surface and the lower part of the guide plate 13 is submerged in the water, when the collection chamber 12 and the guide plate 13 move back and forth with the horizontal plate 4, the fibers in the water can enter the collection chamber 12 along the guide plate 13 with the water and be trapped inside the collection chamber 12, so as to collect the fibers in the water. This prevents the perforated plate 11 from being unable to be cleaned well due to too many floating fibers in the water after the opening mixer has been working for a long time. Thus, without the need to replace the water, the continuous working time of the opening mixer can be further extended. The position of the collection chamber 12 can be limited by the limiting plate 20 to ensure that the collection chamber 12 can always move back and forth with the horizontal plate 4 and prevent the collection chamber 12 from tipping over and failing to function properly. The sharp corner of the protrusion 21 can agitate the water at the bottom to a certain extent, thereby causing the fibers in the water to float to the surface and preventing a large number of fibers from sinking to the bottom and not being collected by the collection chamber 12. Furthermore, the friction between the protrusion 21 and the negative pressure chamber 2 can be reduced by the various ball bearings 22.

[0031] The working principle of the opening mixer is explained in detail below: When the blower 3 is working, the dust and floating fibers inside the machine body 1 are sucked into the negative pressure chamber 2 through the air inlet at the bottom front of the negative pressure chamber 2. The dust and fibers are effectively blocked by the rear perforated plate 11 and the water that submerges the bottom of the perforated plate 11. At this time, the weight of the rear perforated plate 11 can be offset by the larger air pressure inside the rear hollow cylinder 7. When it is necessary to clean the rear perforated plate 11, as the horizontal plate 4 and the slider 5 move forward under the action of the connecting rod 16 and the electric push rod 17, the air pressure inside the rear hollow cylinder 7 can be gradually reduced until the air pressure can no longer effectively offset the weight of the perforated plate 11. At this time, the rear perforated plate 11 can enter the water body and be cleaned as the rear hollow cylinder 7 continues to move forward with the horizontal plate 4 and the slider 5. The principle is that before the rear perforated plate 11 enters the water, the front perforated plate 11 has already moved upward with the forward movement of the horizontal plate 4 and the slider 5 under the influence of the air pressure inside the corresponding hollow cylinder 7, the connecting rod 8, the vertical plate 9, and the rotating plate 10, until it reaches the limit position. After reaching the limit position, as the rear perforated plate 11 moves downward, the air pressure inside the front hollow cylinder 7 can begin to increase, thus preparing for the subsequent downward movement of the front perforated plate 11, so as to ensure that the front and rear perforated plates 11 can be cleaned in sequence. In addition, when the horizontal plate 4 moves, it can drive the collection chamber 12 to move accordingly. After the fibers in the water enter the collection chamber 12 along the guide plate 13 with the water, they will be trapped inside the collection chamber 12 to achieve the purpose of collecting the fibers in the water, so as to avoid the excessive fibers in the water affecting the cleaning of the perforated plate 11 by the water.

[0032] like Figures 1-6 These are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
