Description

Technical Field

[0001] This application relates to the field of material mixing equipment technology, and in particular to a bucket lid lifting device for a mixing cylinder. Background Technology

[0002] In industries such as chemical, food, pharmaceutical, and building materials, it is often necessary to stir and mix materials in a mixing drum (or mixing tank). To ensure effective mixing, prevent material splashing, and isolate the material from external environmental contamination, a lid is usually placed over the opening of the mixing drum.

[0003] In existing technologies, covers are divided into simple cover plate type and integrated agitator type. The simple cover plate type only has necessary feeding holes or observation holes, and the agitator is independently installed outside the material cylinder or on a support. This type of cover is lighter, but has poor sealing and integration, and the agitator installation is complex. The integrated agitator type, in order to optimize equipment layout and improve sealing, integrates the agitator motor, drive shaft, and agitator blades directly onto the cover. This integrated design has a compact structure and good sealing effect, and is a common form of modern mixing equipment.

[0004] The integration of heavy components such as motors, reducers, and drive shafts significantly increases the overall weight of the lid. Workers need to frequently open and close the lid when feeding materials, cleaning, or performing maintenance. The heavy lid requires workers to expend considerable physical strength to lift and move, resulting in high labor intensity and impacting production rhythm and operational efficiency.

[0005] Therefore, there is an urgent need for a solution that can improve the opening and closing efficiency of integrated stirrer-type lids, thereby increasing production cycle time and operational efficiency. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a bucket lid lifting device for a mixing drum, which solves the technical problem of the difficulty in opening and closing the lid of an integrated agitator.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A bucket lid lifting device for a mixing cylinder includes: a frame, the frame being installed on one side of the mixing cylinder, and a bucket lid being provided on the frame; a lifting frame, the lifting frame being liftably mounted on the frame; a lifting assembly, the lifting assembly being installed on the frame, the lifting assembly being used to lift the lifting frame; and a connecting assembly, the connecting assembly being installed on the lifting frame, the connecting assembly being used to mount the bucket lid on the lifting frame.

[0008] Furthermore, the lifting assembly includes a lifting guide rail, on which a slider is provided, the lifting frame is mounted on the slider, and a drive cylinder is provided on the bucket lid and mounted on the slider, with one end of the piston rod of the drive cylinder connected to an external support plate.

[0009] Furthermore, the connecting assembly includes a support block and a clamping block, a connecting cylinder is installed on the lifting frame, one end of the piston rod of the connecting cylinder passes through the support block and connects to the clamping block, and a clamping groove is formed between the support block and the clamping block.

[0010] Furthermore, both the support block and the clamping block are provided with positioning pins, and a support spring is provided between the positioning pin and the corresponding support block and clamping block. One end of the support spring is connected to the positioning pin, and the other end is connected to the corresponding support block and clamping block.

[0011] Furthermore, a bearing is fitted onto the drive cylinder, the barrel cover is mounted on the bearing, and a positioning hole is provided on the bearing, with the positioning pin engaging with the positioning hole.

[0012] Furthermore, a limiting plate is installed on the lifting frame, and limiting rods are formed on both sides of the bucket lid located on the limiting plate, and the limiting rods limit the bucket lid.

[0013] Furthermore, a guide slope is formed between the support block and the clamping block, the guide slope faces the side close to the clamping groove, a connecting bolt is provided on one side of the clamping block, one end of the connecting bolt passes through the clamping block, the support block and the lifting frame in sequence, and a nut is threaded to the end of the connecting bolt that passes through the lifting frame, the nut abutting against the lifting frame.

[0014] In summary, this application includes at least one of the following beneficial technical effects of a bucket lid lifting device for a mixing drum: This application achieves mechanized automatic opening and closing of the lid of a tank equipped with a heavy-duty mixer by setting up a lifting frame driven by a lifting component and connecting components. Operators no longer need to expend enormous physical strength to lift and move the lid, greatly reducing labor intensity. The opening and closing process of the lid is fast and smooth, significantly shortening the preparation time required for feeding, cleaning, or maintenance, thereby effectively improving overall operating efficiency and equipment production cycle time; The drive cylinder, guide rail, and slider are integrated and mounted on the frame, without occupying excessive additional space. The connecting assembly uses a cylinder-driven support block and clamping block, and is equipped with guide ramps and positioning pins, improving the centering, stability, and ease of separation when connecting to the lid. The limit plate further prevents the lid from shaking or deflecting during lifting, improving the smoothness and reliability of the entire lifting process, making it suitable for frequent operation in industrial environments. The design of the connecting components enables quick and accurate docking and locking with the lid, resulting in a high degree of automation and ease of operation. This design not only reduces the need for modifications to the equipment itself, but also allows it to be adapted to various sizes of integrated stirrer lids, enhancing the device's versatility.

[0017] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a bucket lid lifting device for a mixing cylinder.

[0020] Reference Figure 1 A bucket lid lifting device for a mixing cylinder includes a frame 1, a lifting frame 2 is provided on the frame 1, a bucket lid 21 is provided on one side of the lifting frame 2, a connecting component 3 is provided on the lifting frame 2, the connecting component 3 connects the bucket lid 21 to the lifting frame 2, and a lifting component 4 is provided on the frame 1, the lifting component 4 drives the lifting frame 2 to move up and down on the frame 1.

[0021] Reference Figures 2-3 The lifting assembly 4 includes a lifting guide rail 41, which is vertically mounted on the frame 1. A slider 42 is provided on the lifting guide rail 41. The slider 42 is lifted, and a drive cylinder 43 is provided on the bucket cover 21.

[0022] Two sets of connecting components 3 are provided corresponding to the slider 42. The two sets of connecting components 3 have the same structure and function. Only one set will be described below. The connecting component 3 includes a support block 31 and a clamping block 32, and a clamping groove 33 is formed between the support block 31 and the clamping block 32.

[0023] The drive cylinder 43 is vertically oriented, and the support block 31 and clamping block 32 clamp the drive cylinder 43. One end of the piston rod of the drive cylinder 43 is connected to the external support plate. In use, the piston rod of the drive cylinder 43 extends, allowing the bucket lid 21 to rise and fall along the lifting guide rail 41 on the frame 1. The lifting guide rail 41 guides the lifting frame 2, thereby improving the stability of the lifting frame 2 when the drive cylinder 43 drives it to rise and fall.

[0024] The lifting frame 2 is equipped with a connecting cylinder 34. Two sets of connecting cylinders 34 are arranged at intervals on the lifting frame 2. Both sets of connecting cylinders 34 are installed on the frame 1, and one end of the piston rod of the connecting cylinder 34 passes through the support block 31 and the clamping block 32, and the piston rod of the connecting cylinder 34 is connected to the clamping block 32.

[0025] A buffer spring 35 is formed between the support block 31 and the clamping block 32. The buffer spring 35 is sleeved on the piston rod connected to the cylinder 34, and the two ends of the buffer spring 35 are respectively pressed against the support block 31 and the clamping block 32. The buffer spring 35 buffers the support block 31 and the clamping block 32, thereby improving the stability of the clamping of the support block 31 and the clamping block 32.

[0026] Furthermore, a guide slope 311 is formed between the support block 31 and the clamping block 32, and the guide slope 311 is inclined toward the side closer to the clamping groove 33. The guide slope 311 between the support block 31 and the clamping block 32 guides the drive cylinder 43, so that the drive cylinder 43 can be installed in the clamping groove 33 between the support block 31 and the clamping block 32.

[0027] To improve the stability between the support block 31 and the clamping block 32, a connecting bolt 36 is provided on the clamping block 32. One end of the connecting bolt 36 passes through the clamping block 32, the support block 31 and the lifting frame 2 in sequence. The end of the connecting bolt 36 passing through the lifting frame 2 is threaded with a nut 361. The nut 361 is pressed against the lifting frame 2.

[0028] Positioning pins 37 are provided on the support block 31 and the clamping block 32. Several positioning pins 37 are spaced apart on the support block 31 and the clamping block 32 around the axis of the clamping groove 33. The positioning pins 37 are arranged vertically as a whole. A support spring 371 is provided between the positioning pin 37 and the corresponding support block 31 and clamping block 32. One end of the support spring 371 is connected to the positioning pin 37, and the other end is connected to the corresponding support block 31 and the frame block.

[0029] A bearing 22 is installed on the bucket lid 21. The bearing 22 is mounted on the drive cylinder 43. The bearing 22 has a positioning hole 23. Several positioning holes 23 are spaced around the bearing 22. When the support block 31 and the clamping block 32 clamp the drive cylinder 43, the positioning pins 37 on the support block 31 and the clamping block 32 are inserted into the positioning holes 23 of the bearing 22 under the action of the support spring 371. The bucket lid 21 is positioned by the positioning pins 37.

[0030] Furthermore, to improve the stability of the bucket lid 21 rotating on the lifting frame 2, a limiting plate 24 is formed on the lifting frame 2. The limiting plate 24 is integral with the lifting frame 2. Limiting rods 25 are formed on both sides of the bucket lid 21 located on the limiting plate 24. As the bucket lid 21 rotates, the limiting rods 25 abut against the limiting plate 24. This ensures that the bucket lid 21 can only rotate between the angles of the two limiting rods 25, improving the stability of the bucket lid 21 during use, preventing excessive rotation of the bucket lid 21, and improving the ease of use of the bucket lid 21.

[0031] The implementation principle of the bucket lid lifting device for a mixing drum in this embodiment is as follows: the driving cylinder 43 drives the bucket lid 21 to rise and fall, which is converted into the linear motion of the slider 42 on the lifting guide rail 41, so as to achieve smooth lifting and lowering of the bucket lid 21. The connecting component 3 uses a cylinder to drive the clamping block 32 and the support block 31 to form a clamping groove 33, which, together with the buffer spring 35, absorbs vibration and ensures clamping stability. The guide slope 311 guides the driving cylinder to be embedded into the clamping groove 33, and at the same time, the positioning pin 37 is inserted into the positioning hole 23 of the bearing 22 under the action of the support spring 371 to achieve precise positioning. The limiting plate 24 and the limiting rod 25 limit the rotation angle of the bucket lid 21 to prevent excessive rotation.

[0032] The above 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 in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
