Description

Technical Field

[0001] This utility model relates to the field of frozen food production technology, and in particular to an adjustable speed stirring control device. Background Technology

[0002] After the ice cream ingredients are mixed, they need to be aged in an aging tank for 4-72 hours. The purpose is to allow the emulsifiers, stabilizers, sugar, and milk to mix thoroughly and form a more stable texture. During this process, the aging tank needs to be stirred. However, due to the different mixing amounts of batches, when the amount of ice cream ingredients and the stirring paddle are exactly on the same plane, it is easy to stir up a lot of foam, which not only causes material loss but also affects the texture of the ingredients themselves.

[0003] In existing technologies, frequency converters (i.e., speed-adjustable stirring control devices) are usually added to the motor of the stirring paddle in the material aging tank, so that the stirring speed is changed from a fixed speed to an adjustable speed. The stirring speed can be adjusted at any time according to the amount of material in the tank, which can effectively prevent foaming and maintain the original structure of the material.

[0004] To save space in the factory and facilitate operation, existing frequency converters are usually installed on the wall next to the aging tank. For secure installation, expansion bolts are used to fix them to the wall. Installation and disassembly are cumbersome and inconvenient for later disassembly and maintenance of the frequency converter. Therefore, an adjustable speed stirring control device is needed.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: Reference Figures 1-4 The adjustable speed stirring control device shown includes a frequency converter body 1 and a fixed bracket 2 fixed on the ground. The frequency converter body 1 has an integrally formed mounting back plate 11 on the rear side, and mounting holes are provided at the four corners of the mounting back plate 11.

[0029] The front side of the fixed bracket 2 is fixed with multiple movable mounting posts 3 that pass through the mounting holes of the mounting back plate 11, and L-shaped limiting grooves 31 are opened on the mounting posts 3;

[0030] Multiple mounting posts 3 are movably fitted with fixing sleeves 4. One end of the fixing sleeve 4 is pressed against the front side wall of the mounting back plate 11. The inner side of the fixing sleeve 4 is integrally formed with a limiting block 41. The limiting block 41 is slidably engaged in the limiting groove 31. The fixing sleeve 4 is engaged with the mounting post 3 through the cooperation of the limiting block 41 and the limiting groove 31.

[0031] Based on the above structure, when it is necessary to install the inverter body 1, simply put the mounting back plate 11 of the inverter body 1 onto the multiple mounting posts 3 at the predetermined installation position, and then put several fixing sleeves 4 onto the mounting posts 3 in sequence, so that the ends of the fixing sleeves 4 are pressed against the front side wall of the mounting back plate 11. During this process, simply put the fixing sleeves 4 onto the mounting posts 3 so that the limiting block 41 slides into the limiting groove 31. Then rotate the fixing sleeves 4 so that the limiting block 41 is engaged in the limiting groove 31, thus completing the fixing of the mounting back plate 11. The inverter body 1 can then be fixedly installed on the fixed bracket 2.

[0032] When it is necessary to disassemble the inverter body 1 for maintenance, simply rotate the fixing sleeve 4 in the reverse direction and move the fixing sleeve 4 away from the fixing bracket 2 to remove the fixing sleeve 4 and release the restriction on the mounting back plate 11. At this time, the inverter body 1 can be removed for maintenance.

[0033] The installation and disassembly operations are simple and quick, making it convenient to disassemble and maintain the inverter body 1 when it malfunctions or needs maintenance after a period of use, making it flexible and convenient to use.

[0034] Furthermore, the limiting groove 31 includes an axial groove 311 and a circumferential groove 312. The axial groove 311 is a straight groove parallel to the axis of the mounting post 3, and the opening of the axial groove 311 is located at the front end of the mounting post 3. The circumferential groove 312 is an arc-shaped groove extending along the circumference of the mounting post 3, and one end of the circumferential groove 312 is connected to one end of the axial groove 311.

[0035] The limiting block 41 is inserted into the axial groove 311 from the opening of the axial groove 311. After the limiting block 41 enters the circumferential groove 312, it rotates and is locked at the end of the circumferential groove 312 away from the axial groove 311. This makes it easier to lock the fixing sleeve 4 onto the mounting post 3 and achieve the purpose of limiting the mounting back plate 11 by using the fixing sleeve 4.

[0036] Furthermore, an elastic tension ring 7 is fixed to one end of the opening of the fixed sleeve 4. When the fixed sleeve 4 is fitted and snapped onto the mounting column 3, the elastic tension ring 7 and the mounting column 3 are interference-fitted, which makes the snapping of the fixed sleeve 4 and the mounting column 3 more stable, reduces the probability of the fixed sleeve 4 falling off when touched by an accidental external force, and improves the safety of the inverter body 1 after installation.

[0037] Furthermore, the fixed bracket 2 has a wire-passing gap 21 that runs through the front and back of the fixed bracket 2, and a horizontally extending wiring groove 22 is provided on the bottom back side of the fixed bracket 2. A support groove 221 communicating with the wiring groove 22 is provided on the back side of the column between every two wire-passing gaps 21. The support groove 221 extends vertically, and a wire-passing hole 23 that runs horizontally through the column is provided on both sides of the column between every two wire-passing gaps 21. The wire-passing hole 23 communicates with the support groove 221.

[0038] Cables extending into the support groove 221 are threaded through the wiring groove 22. The cables in the support groove 221 pass through the wire hole 23 and are fixed to the wiring terminals of the inverter body 1.

[0039] By routing the cables through the rear wiring trough 22 and the branch trough 221, the distribution of the cables can be made more regular, which is convenient for wiring and facilitates the maintenance and repair of the cables in the future, further improving the convenience of the later maintenance of the adjustable speed stirring control device.

[0040] Furthermore, multiple sets of limiting buckles 5 are installed on the back side of the fixed bracket 2 between the side walls on both sides of the support groove 221. They are evenly distributed along the back side of the fixed bracket 2 and correspond to the support groove 221. The limiting buckle 5 includes two short shafts 51 fixed on both sides of the support groove 221 and a locking block 52 rotatably sleeved on one of the short shafts 51. The locking block 52 has a locking groove 521 that engages with the other short shaft 51. The ends of the two short shafts 51 away from the fixed bracket 2 are integrally formed with a limiting end plate 511 with a diameter larger than that of the short shaft 51.

[0041] With the limit buckle 5 in place, when wiring is required, the buckle 52 is rotated to disengage from the other short shaft 51 and rotated to the outside of the opening of the support groove 221, so that the cable can be laid in the support groove 221. Then, the buckle 52 is rotated in the opposite direction so that the buckle 52 is engaged with the other short shaft 51, which can seal the opening of the support groove 221 (interval strip sealing), making it difficult for the cable to fall out of the support groove 221, reducing the probability of cable tangling, improving the standardization of wiring, and making it easier for subsequent disassembly, assembly and maintenance.

[0042] Furthermore, multiple wire-blocking teeth 6 are fixed at both the upper and lower ends of the wiring trough 22. There is a gap between the upper end of the lower wire-blocking tooth 6 and the top wall of the wiring trough 22 for the cable to be inserted, and there is also a gap between the lower end of the upper wire-blocking tooth 6 and the bottom wall of the wiring trough 22 for the cable to be inserted.

[0043] Multiple upper-end line-blocking teeth 6 and multiple lower-end line-blocking teeth 6 are staggered vertically in the horizontal direction, and the upper-end line-blocking teeth 6 and multiple lower-end line-blocking teeth 6 coincide at their upper ends in the horizontal direction.

[0044] The cable can be limited within the wiring trough 22, thereby ensuring the reliability of the cable routing within the wiring trough 22, and also making it easy to remove the cable and use.

[0045] The working principle of this utility model is as follows: In daily use, when it is necessary to install the inverter body 1, simply put the mounting back plate 11 of the inverter body 1 onto the multiple mounting posts 3 at the predetermined installation position, and then put several fixing sleeves 4 onto the mounting posts 3 in sequence, so that the end of the fixing sleeve 4 (here referring to the elastic tension ring 7) abuts against the front side wall of the mounting back plate 11. During this process, simply put the fixing sleeve 4 onto the mounting post 3 so that the limiting block 41 slides into the axial groove 311. Then rotate the fixing sleeve 4 so that the limiting block 41 is engaged in the circumferential groove 312, thus completing the fixing of the mounting back plate 11. The inverter body 1 can then be fixedly installed on the fixed bracket 2. At the same time, the elastic tension ring 7 and the mounting post 3 are interference-fitted, so that the engagement between the fixing sleeve 4 and the mounting post 3 is more stable.

[0046] When it is necessary to disassemble the inverter body 1 for maintenance, simply rotate the fixing sleeve 4 in the reverse direction and move the fixing sleeve 4 away from the fixing bracket 2 to remove the fixing sleeve 4 and release the restriction on the mounting back plate 11. At this time, the inverter body 1 can be removed for maintenance.

[0047] It should be further noted that the technical features of the inverter body 1, cables, etc. involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field, and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
