Description

Technical Field

[0001] This utility model relates to the field of polishing machine frame technology, specifically to a splicing frame and a polishing machine. Background Technology

[0002] Rice polishing machines use friction and pressure to gelatinize the starch on the surface of rice grains, forming a gel film that gives the rice a crystal-clear appearance. They are also used to remove residual bran powder from the surface of rice grains after milling, thus improving the cleanliness and appearance of the rice.

[0003] The rice polishing machine mainly includes a frame, polishing mechanism, bran collection hopper, and drive mechanism. The polishing mechanism includes a main shaft, polishing roller, and sieve cylinder. The main shaft is rotatably connected to the frame. The polishing roller is sleeved on the main shaft and placed in the polishing chamber of the frame. The sieve cylinder is connected to the frame and sleeved on the polishing roller. The bran collection hopper is connected to the frame and located below the sieve cylinder. The drive mechanism includes a motor and a belt drive mechanism. The motor is fixed to the frame. The belt drive mechanism connects the main shaft and the output shaft of the motor. The main shaft is driven to rotate through the motor and belt drive mechanism. The rotating main shaft polishes the rice in the sieve cylinder.

[0004] Currently, the frames of polishing machines are generally formed by welding sheet metal at sheet metal manufacturers. After welding, the sheet metal is transported from the sheet metal manufacturer to the manufacturer, who then installs the polishing mechanism and drive mechanism on the frame before selling it. However, the welded frame is relatively large. When transporting the welded frame, since the shape of the frame is fixed, only 2-3 frames can be transported at a time, which increases transportation costs. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a splicing frame and polishing machine to solve the technical problem that the frame of the existing polishing machine is large and the transportation cost to the manufacturer is increased.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, this utility model provides a modular rack, comprising:

[0008] The first bracket has a first fixing hole for the main shaft to pass through;

[0009] The second bracket is spaced apart from the first bracket and has a second fixing hole opposite to the first fixing hole; and

[0010] The beam assembly includes multiple beams that are parallel to each other and spaced apart. One end of each beam is detachably connected to the first support and the other end is detachably connected to the second support. A space is formed between the beams for installing a polishing mechanism and a chaff collection hopper.

[0011] In one embodiment, both the first bracket and the second bracket are provided with multiple insertion holes;

[0012] The two ends of the crossbeam are respectively inserted into the first bracket and the second bracket through the insertion holes.

[0013] In one embodiment, the plurality of crossbeams are a first crossbeam and a second crossbeam. The plurality of first crossbeams are arranged in a rectangular array, and a first mounting space for installing a polishing mechanism is formed between the plurality of first crossbeams. The second crossbeam is disposed below the first crossbeams, and a second mounting space for installing a chaff collection hopper is formed between the second crossbeam and the first crossbeam.

[0014] In one embodiment, the beam assembly further includes a plurality of vertical beams arranged parallel to each other, the vertical beams being disposed between the second beam and the first beam, and the two ends of the vertical beams being detachably connected to the first beam and the second beam, respectively.

[0015] In one embodiment, the crossbeam assembly further includes at least one longitudinal beam, the two ends of which are detachably connected to the two second crossbeams.

[0016] In one embodiment, the beam assembly further includes a top plate, which includes a top plate and side plates formed by bending the top plate on both sides. The top plate is disposed on the top of the second beam and has a ventilation window open relative to the first installation space. The two side plates are respectively disposed on the opposite side of the two second beams and are detachably connected to the two second beams respectively.

[0017] In one embodiment, the crossbeam assembly further includes a plurality of reinforcing members, which are respectively disposed on both sides of the first mounting space. The reinforcing members connect two adjacent first crossbeams, and an observation window communicating with the first mounting space is formed between the reinforcing members and the two adjacent first crossbeams.

[0018] In one embodiment, the beam assembly further includes a fastener that connects the two second beams and forms a fixing space for fixing the motor.

[0019] In one embodiment, both the first support and the second support are provided with multiple weight-reducing grooves.

[0020] Secondly, this utility model also provides a polishing machine, including the above-mentioned spliced ​​frame.

[0021] Compared with the prior art, the modular frame and polishing machine provided by this utility model require only the production of the first support, the second support, and the crossbeam assembly when the sheet metal manufacturer manufactures the frame. During transportation, the first support, the second support, and multiple crossbeams are packaged independently, which can significantly reduce the transportation volume occupied by the frame and reduce logistics costs.

[0022] Moreover, due to the long lateral distance of the rack, by detachably connecting the crossbeam to the first and second supports, the crossbeam can be placed separately from the first and second supports during transportation, which can greatly reduce the lateral dimension of the rack, reduce the transportation volume occupied by the rack, and further reduce logistics costs.

[0023] When the modular frame is transported to the manufacturer, the first support, the second support, and the crossbeam are assembled. The assembled frame can stably support the polishing mechanism and the chaff collection hopper. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0039] To address the technical problem of the large size of the polishing machine frame 11, which increases transportation costs to the manufacturer, this utility model provides a modular frame and polishing machine, which can solve the problem of high transportation costs caused by the large size of the frame 11.

[0040] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a modular frame in one embodiment of the present invention. The modular frame includes a first support 1, a second support 2, and a crossbeam assembly 3. The first support 1 has a first fixing hole 1a for the main shaft to pass through. The second support 2 is spaced apart from the first support 1 and has a second fixing hole 2a opposite to the first fixing hole 1a. The crossbeam assembly 3 includes multiple crossbeams 31, which are parallel to each other and spaced apart. One end of each crossbeam 31 is detachably connected to the first support 1, and the other end is detachably connected to the second support 2. A space is formed between the multiple crossbeams 31 for the installation of the polishing mechanism and the chaff collection hopper.

[0041] Specifically, when producing the frame, the board manufacturer only needs to produce the first support 1, the second support 2, and the crossbeam assembly 3. During transportation, the first support 1, the second support 2, and the multiple crossbeams 31 are packaged separately, which can significantly reduce the transportation volume occupied by the frame and reduce logistics costs.

[0042] Moreover, since the frame has a long lateral distance, by detachably connecting the crossbeam 31 to the first support 1 and the second support 2, the crossbeam 31 can be placed separately from the first support 1 and the second support 2 during transportation, which can greatly reduce the lateral dimension of the frame, reduce the transportation volume occupied by the frame, and further reduce logistics costs.

[0043] When the modular frame is transported to the manufacturer, the first support 1, the second support 2, and the crossbeam 31 are assembled. The assembled frame can stably support the polishing mechanism and the chaff collection hopper.

[0044] It should be understood that the crossbeam 31 can be detachably connected to the first support 1 and the second support 2 by means of bolts, screws and clips. Specifically, in one embodiment, the crossbeam 31 is connected to the first support 1 and the second support 2 by bolts.

[0045] It should be understood that the direction in which the crossbeam 31 is set is parallel to the axis of the first fixing hole 1a and the second fixing hole 2a, or it can be understood that the direction in which the crossbeam 31 is set is parallel to the axis of the main shaft of the polishing mechanism in the polishing machine.

[0046] It should be understood that the first support 1, the second support 2, and the crossbeam 31 can be arranged by means of abutment or insertion, specifically, as follows: Figure 2 , Figure 5 and Figure 6 As shown, in one embodiment, both the first bracket 1 and the second bracket 2 are provided with multiple insertion holes b; the two ends of the crossbeam 31 are respectively inserted into the first bracket 1 and the second bracket 2 through the insertion holes b.

[0047] By inserting the two ends of the crossbeam 31 into the first bracket 1 and the second bracket 2 respectively, the first bracket 1 and the second bracket 2 can temporarily limit the crossbeam 31 in the height direction after insertion. When connecting the crossbeam 31 with the first bracket 1 and the second bracket 2 in the future, there is no need to manually lift or support the crossbeam 31, which facilitates assembly.

[0048] It should be understood that, among the multiple crossbeams 31, in order to form an installation space to accommodate the polishing mechanism and the chaff collection hopper, therefore, as Figure 4 As shown, in one embodiment, the plurality of crossbeams 31 are a first crossbeam 311 and a second crossbeam 312. The plurality of first crossbeams 311 are arranged in a rectangular array, and a first installation space 31a for installing the polishing mechanism is formed between the plurality of first crossbeams 311. The second crossbeam 312 is disposed below the first crossbeam 311, and a second installation space 31b for installing the chaff collection hopper is formed between the second crossbeam 312 and the first crossbeam 311.

The specific installation method of the structure in the polishing mechanism can be to connect and fix it by means of bolts, screws and welding. A chaff collection hopper is set between the first crossbeam 311 and the second crossbeam 312.

The vertical beams 32 are disposed between the second crossbeam 312 and the first crossbeam 311, and the two ends of the vertical beams 32 are detachably connected to the first crossbeam 311 and the second crossbeam 312, respectively.

[0052] By setting up a vertical beam 32, which connects the first horizontal beam 311 and the second horizontal beam 312, the structural strength between the first horizontal beam 311 and the second horizontal beam 312 can be strengthened, and at the same time, the middle part of the first horizontal beam 311 can be supported.

[0053] It should be understood that the number of vertical beams 32 can be one, two, three, or four, etc. Specifically, for example... Figure 2 and Figure 4 As shown, in one embodiment, there are four vertical beams 32, which are parallel to each other and arranged in a matrix.

[0058] It should be understood that the longitudinal beam 33 and the second transverse beam 312 can be detachably connected by means of bolts, screws and clips.

[0059] It should be understood that the longitudinal beam 33 and the second transverse beam 312 can be arranged crosswise or perpendicularly to each other.

[0060] Specifically, in one embodiment, the longitudinal beam 33, the transverse beam 31, and the vertical beam 32 are perpendicular to each other.

The two side plates 342 are respectively disposed on the opposite side of the two second crossbeams 312 and are detachably connected to the two second crossbeams 312. The side plates 342 are disposed along the length direction of the first crossbeam 311.

[0062] By setting a top plate 341, which is connected to the first crossbeam 311, and forming a ventilation window c, and by bending the top plate 341 on both sides to form side plates 342, the structural strength between the two first crossbeams 311 at the top can be strengthened.

[0065] By setting up a reinforcement member 35, which connects two adjacent first crossbeams 311, the structural strength between the first crossbeams 311 can be strengthened. At the same time, an observation window d is formed between the adjacent first crossbeams 311 and the two reinforcement members 35. By setting up the observation window d, the working condition of the screen cylinder in the frame can be observed through the observation window d.
