Description

Technical Field

[0001] This application belongs to the field of material collection technology, and in particular relates to a mixing device. Background Technology

[0002] Existing mixing equipment typically has a switchable discharge port at the bottom of the mixing drum, and a hopper below the discharge port for discharging materials.

[0003] When receiving materials, a collection bag is placed at the hopper to receive the materials. The lower part of the collection bag is placed against the lower side of the hopper, while the upper side of the bag needs to be manually held open. Then, the discharge port is opened to discharge the materials. During this process, the materials fall into the collection bag and create an upward airflow. This upward airflow carries dust generated during the mixing process and causes it to escape towards the bag opening. Some of the dust adheres to the outer wall of the mixing equipment, while some escapes and is inhaled by workers, which has an adverse effect on the production environment and the workers. Utility Model Content

[0004] This application provides a mixing device that can solve the problem of dust escaping after materials fall into the collection bag during the feeding process, causing adverse effects on the production environment and workers.

[0005] This application provides a stirring device, including:

[0006] A mixing drum, with a discharge port at the bottom;

[0007] A baffle is installed at the discharge port and can cover the discharge port. One end of the baffle is rotatably connected to the outer bottom wall of the mixing drum, and the projection of the other end of the baffle in the height direction of the mixing drum is located on the outside of the mixing drum.

[0008] A locking mechanism is installed on the mixing drum to lock / unlock the baffle from the mixing drum;

[0009] A hopper is located below the discharge port, with the hopper's inlet located below and facing the discharge port; and

[0010] The tightening device, located on the hopper, is used to tighten the opening of the storage bag.

[0011] Optionally, the tightening device includes:

[0012] Support plate, connected to the outer wall of the hopper;

[0013] A rotating shaft passes through a support plate and is rotatably connected to the support plate. The length direction of the shaft's axis is consistent with the discharge direction of the hopper.

[0014] The first rotating roller has one end connected to the rotating shaft, and the length direction of the axis of the first rotating roller is consistent with the length direction of the axis of the rotating shaft.

[0015] The second roller has one end connected to the rotating shaft, and the length direction of the axis of the second roller is consistent with the length direction of the axis of the rotating shaft.

[0016] Torque output device, used to rotate the shaft.

[0017] Optionally, the torque output device includes a hand crank, the output end of which is connected to the rotating shaft.

[0018] Optionally, the torque output device includes a motor, the output end of which is connected to a rotating shaft, and the drive end of which is electrically connected to an external power source.

[0019] Optionally, the outer surfaces of the first and second rollers are evenly distributed with multiple protrusions, and the outer surfaces of the first and second rollers are both made of rubber.

[0020] Optionally, the locking mechanism includes a snap-fit ​​component and an elastic component. The snap-fit ​​component is rod-shaped and has a connecting part, a rotating part, and a snap-fit ​​part arranged sequentially along its length. The rotating part is rotatably connected to the stirring cylinder, and the connecting part is connected to the stirring cylinder through the elastic component. The elastic component is in a stretched state, and the snap-fit ​​part can snap-fit ​​with the baffle under the action of the elastic component.

[0021] Optionally, the baffle has a protrusion, which is rod-shaped and located on the opposite side of the baffle and the outer bottom wall of the mixing cylinder for rotational connection. The engaging part has a latch, which can rotate under the action of the elastic element, so that the latch engages with the protrusion.

[0022] Optionally, the locking mechanism also includes a limiting member, which is semi-circular and is located on the outer wall of the mixing drum. One end of the snap-fit ​​member near the connection extends into the limiting member, and the snap-fit ​​member can engage with the baffle and abut against the limiting member under the action of the elastic member.

[0023] Optionally, the plane where the discharge port of the hopper is located is vertical, and a backflow preventer is installed at the discharge port. The backflow preventer covers the discharge port, and the two ends of the upper side of the backflow preventer are rotatably connected to the left and right side walls of the hopper. The backflow preventer can rotate relative to the hopper with the upper side as the axis. The aperture of the mesh on the backflow preventer is smaller than the diameter of the dust of the material being mixed.

[0024] Optionally, the mixing device also includes a lid, which is basin-shaped and is fastened onto the opening of the mixing drum to cover it.

[0025] The mixing equipment provided in this application, when the material needs to be discharged after being mixed in the mixing drum, places a collection bag over the discharge port of the discharge hopper. The bag opening is contracted to fit against the outer wall of the discharge hopper by a tightening device. The baffle can rotate relative to the mixing drum by a locking device, so that the discharge port is connected to the discharge hopper. The material falls from the discharge port and enters the collection bag along the discharge hopper. Because the bag opening is tightened to fit against the outer wall of the discharge hopper, dust can only move towards the discharge hopper and discharge port during discharge, which greatly reduces the escape of dust and reduces the impact on the production environment and workers.

[0060] Currently, during the material feeding process, dust escapes after the material falls into the collection bag, causing adverse effects on the production environment and staff.

[0061] To address the aforementioned problems, one embodiment of this application provides a stirring device, such as... Figure 1 and Figure 5 As shown, the mixing equipment includes a mixing drum 1, a baffle 2, a locking mechanism 3, a hopper 4, and a tightening device 5. The mixing drum 1 has a discharge port 11 at its bottom. The baffle 2 is located at the discharge port 11 and covers it. One end of the baffle 2 is rotatably connected to the outer bottom wall of the mixing drum 1, and the projection of the other end of the baffle 2 in the height direction of the mixing drum 1 is located outside the mixing drum 1. The locking mechanism 3 is located on the mixing drum 1 and is used to lock / unlock the baffle 2 and the mixing drum 1. The hopper 4 is located below the discharge port 11, and the inlet of the hopper 4 is located below the discharge port 11 and faces the discharge port 11. The tightening device 5 is located on the hopper and is used to tighten the opening of the storage bag.

[0062] When the material is finished mixing in the mixing drum 1 and needs to be discharged, the collection bag is placed on the discharge port 41 of the discharge hopper 4. The bag opening is contracted to fit against the outer wall of the discharge hopper 4 by the tightening device 5. The baffle 2 can rotate relative to the mixing drum 1 by the locking device, so that the discharge port 11 is connected to the discharge hopper 4. The material falls from the discharge port 11 and enters the collection bag along the discharge hopper 4. Because the bag opening is tightened to fit against the outer wall of the discharge hopper 4, the dust can only move towards the discharge hopper 4 and the discharge port 11 during discharge, which greatly reduces the escape of dust and reduces the impact on the production environment and workers.

[0063] It should be noted that the mixing drum 1 is mounted on the frame 9, and the mixing device inside the mixing drum 1 is a structure commonly used in the prior art. For example, the mixing drum 1 includes a mixing mechanism and a driving mechanism, etc. The mixing mechanism includes a mixing blade disposed at the bottom of the mixing drum 1, and the driving mechanism includes a drive motor connected to the mixing blade and a power supply for powering the drive motor, etc. These are all conventional settings or means in the prior art, so they will not be described in detail here.

[0064] In some embodiments of this application, such as Figure 4 As shown, the tightening device 5 includes a support plate 51, a rotating shaft 52, a first rotating roller 53, a second rotating roller 54, and a torque output device 55; the support plate 51 is connected to the outer wall of the hopper; the rotating shaft 52 passes through the support plate 51 and is rotatably connected to the support plate 51, and the length direction of the axis of the rotating shaft 52 is consistent with the discharge direction of the hopper 4; one end of the first rotating roller 53 is connected to the rotating shaft 52, and the length direction of the axis of the first rotating roller 53 is consistent with the length direction of the axis of the rotating shaft 52; one end of the second rotating roller 54 is connected to the rotating shaft 52, and the length direction of the axis of the second rotating roller 54 is consistent with the length direction of the axis of the rotating shaft 52; the torque output device 55 is used to rotate the rotating shaft 52.

[0065] The tightening device 5 is used to shrink the opening of the storage bag to fit against the outer wall of the hopper 4. The worker puts the storage bag on the hopper 4 and extends the excess part of the bag opening between the first roller 53 and the second roller 54. The torque output device 55 is used to rotate the shaft 52, causing the first roller 53 and the second roller 54 to rotate and wrap the storage bag at the opening, thereby tightening the storage bag to fit against the outer wall of the hopper 4. Then the torque output device 55 is stopped.

[0066] In some embodiments of this application, such as Figure 4 As shown, the tightening device 5 also includes a connecting rod 56, the middle part of which is connected to the output end of the rotating shaft 52, one end of the first rotating roller 53 is connected to one end of the connecting rod 56, and one end of the second rotating roller 54 is connected to the other end of the connecting rod 56.

[0067] The middle part of the connecting rod 56 is connected to the output end of the rotating shaft 52, one end of the first rotating roller 53 is connected to one end of the connecting rod 56, and one end of the second rotating roller 54 is connected to the other end of the connecting rod 56, so that the coiling efficiency of the storage bag is higher when the rotating shaft 52 drives the first rotating roller 53 and the second rotating roller 54 to rotate.

[0068] In some embodiments of this application, the rotating shaft 52 is connected to the support plate 51 via a bearing.

[0069] The aforementioned bearings enable the shaft 52 to rotate more smoothly.

[0070] In some embodiments of this application, the torque output device includes a hand crank, the output end of which is connected to a rotating shaft.

[0071] Workers can rotate the shaft by turning a hand crank, which in turn rotates the first and second rollers, thereby coiling the storage bag that extends between the first and second rollers.

[0072] In some embodiments of this application, such as Figure 4 As shown, the torque output device 55 includes a motor 551, the output end of the motor 551 is connected to the rotating shaft 52, and the drive end of the motor 551 is electrically connected to an external power source.

[0073] Workers turn on motor 551 to drive the rotating shaft, which in turn causes the first and second rollers to rotate, thereby coiling the storage bag that extends between the first and second rollers.

[0074] It should be noted that the drive end of motor 551 is used to drive the motor to run. It can be electrically connected to an external power source to supply power, or an internal power source can be added to the mixing equipment and the drive end of motor 551 can be electrically connected to the internal power source to supply power to motor 551.

[0075] In some embodiments of this application, the outer surfaces of the first roller and the second roller are provided with a plurality of protrusions, and the outer surfaces of the first roller and the second roller are both made of rubber.

[0076] Multiple protrusions are evenly distributed on the outer surfaces of the first and second rollers to increase friction, enabling the first and second rollers to better coil the storage bag when rotating. The outer surfaces of the first and second rollers are made of rubber, which further increases friction.

[0077] In some embodiments of this application, such as Figures 1 to 3As shown, the locking mechanism 3 includes a snap-fit ​​member 31 and an elastic member 32. The snap-fit ​​member 31 is rod-shaped. The snap-fit ​​member 31 has a connecting part 311, a rotating part 312 and a snap-fit ​​part 313 in sequence along its length. The rotating part 312 is rotatably connected to the stirring cylinder 1. The connecting part 311 is connected to the stirring cylinder 1 through the elastic member 32. The elastic member 32 is in a stretched state. The snap-fit ​​part 313 can snap-fit ​​with the baffle 2 under the action of the elastic member 32.

[0078] The aforementioned elastic element 32 is in a stretched state and connected to the connecting part 311, so that the locking element 31 maintains a rotational tendency with the rotating part 312 as the rotation center. The connecting part 311 always has a tendency to move in the direction of the elastic element 32, while the locking part 313 is located at the other end of the locking element 31 with the rotating part 312 as the center, and has a movement tendency in the opposite direction to the connecting part 311, so that the locking part 313 always has a movement tendency in the direction of the baffle 2, thereby constantly pressing against the baffle 2 so that the locking part 313 and the baffle 2 are in a locking state. By applying a force opposite to the movement tendency and greater than the spring contraction force to one end of the locking element 31 with the connecting part 311, the locking part 313 rotates with the rotating part 312 as the rotation center and separates from the baffle 2, thereby releasing the locking state, so that the baffle 2 can rotate relative to the mixing drum 1, so that the discharge port 11 is connected to the discharge hopper 4, thereby realizing the discharge of materials in the mixing drum 1.

[0079] In some embodiments of this application, such as Figures 1 to 3 as well as Figure 5 and Figure 7 As shown, the baffle 2 has a protrusion 21, which is rod-shaped and located on the opposite side of the baffle 2 and the outer bottom wall of the stirring cylinder 1. The locking part 313 has a latch 3131, which can rotate under the action of the elastic member 32, so that the latch 3131 abuts against and locks the protrusion 21.

[0080] The aforementioned protrusion 21 facilitates the snap-fit ​​of the snap-fit ​​part 313 with the snap-fit ​​slot 3131, and also makes the snap-fit ​​part 313 more stable in terms of force when snapping with the baffle 2, and the snap-fit ​​is more secure.

[0081] In some embodiments of this application, such as Figure 1 As shown, the locking mechanism 3 also includes a limiting member 6, which is semi-circular and is located on the outer wall of the mixing drum 1. The end of the snap-fit ​​member 31 near the connecting part 311 extends into the limiting member 6. The snap-fit ​​member 31 can snap into the baffle 2 and abut against the limiting member 6 under the action of the elastic member 32.

[0082] The aforementioned limiting member 6 is designed to prevent the snap-fit ​​member 31 from rotating excessively. When the snap-fit ​​part 313 of the snap-fit ​​member 31 snaps into the baffle 2, the snap-fit ​​member 31 abuts against the limiting member 6, preventing the snap-fit ​​member 31 from rotating excessively and causing the spring to loosen and fall off.

[0083] In some embodiments of this application, such as Figure 6 and Figure 7 As shown, the plane where the discharge port 41 of the hopper 4 is located is vertical. A backflow preventer 7 is provided at the discharge port 41. The backflow preventer 7 covers the discharge port 41. The two ends of the upper side of the backflow preventer 7 are rotatably connected to the left and right side walls of the hopper 4. The backflow preventer 7 can rotate relative to the hopper 4 with the upper side as the axis. The aperture of the mesh on the backflow preventer 7 is smaller than the diameter of the dust of the material being stirred.

[0084] When the material is fed, the anti-reverse mesh plate 7 rotates relative to the feeding hopper 4 due to gravity, so that the material can pass through smoothly. The airflow brought up by the material falling into the collection bag can pass through the anti-reverse mesh plate 7 smoothly. At the same time, the dust mixed in the airflow cannot pass through the anti-reverse mesh plate 7, thereby further reducing the dust escape.

[0085] In some embodiments of this application, such as Figure 7 As shown, the mixing device also includes a cylinder cover 8, which is basin-shaped and is fastened onto the opening of the mixing cylinder 1 to cover the opening.

[0086] The aforementioned lid 8 is basin-shaped and can be used to store materials to be stirred, while also covering the stirring drum 1 to prevent dust from escaping during the stirring process.

[0087] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles described in this application, and these improvements and modifications should also be considered within the scope of protection of this application.
