Description

Technical Field

[0001] The present application relates to the technical field of corn flaking equipment, and in particular to a corn flaking main machine. Background Art

[0002] Steam flaking technology is a feed processing method that first gels corn starch through wet heat treatment, causing starch granules to absorb water and swell, destroying their crystal structure, and then expelling some straight-chain starch to form a viscous substance. Subsequently, the secondary structure of the protein bound to starch in the corn cells, namely the hydrogen bond, is destroyed through mechanical and physical action, thereby exposing the starch granules and changing the protein structure in the corn. The raw corn is processed through the dual steps of steam heating and mechanical rolling, which changes the chemical composition and physical form of the corn, is conducive to the exposure of corn starch granules and the destruction of the external seed coat, and finally the corn is processed into thin flakes with density and thickness, thereby improving the utilization rate of corn and facilitating digestion and absorption by livestock.

[0003] The main equipment of steam flaking technology includes hot steaming system and mechanical rolling equipment, which runs through the entire equipment through the feeding system, transmission system and control system. Among them, the mechanical rolling equipment is the corn flaking machine we commonly use. The traditional corn flaking machine mainly includes a machine body, in which two pressure rollers are arranged. The two pressure rollers rotate relative to each other, so as to roll the steamed corn kernels into flakes, and then fall onto the conveyor belt for transfer.

[0004] However, there is a problem when using the traditional tablet press:

[0005] Corn kernels are put into the machine from the feed port at the upper end and fall between the two pressure rollers. They flow between the two pressure rollers only by their own weight or stacking pressure. The rotation speed of the two pressure rollers is constant, which can easily cause corn kernels to accumulate on the surface of the two pressure rollers and cause blockage; even if the upper layer is squeezed more solid, the lower layer will not leak out even if it is hollowed out.

[0006] To this end, the present application provides a corn flaking main machine to solve the problem of accumulation and retention of materials during the corn flaking process. Utility Model Content

[0007] The purpose of the present application is to solve the problems existing in the prior art and to propose a corn flake pressing host.

[0008] In order to achieve the above purpose, this application adopts the following technical solutions:

[0009] The corn flaking main machine comprises a casing with openings at the upper and lower ends, wherein two flaking rollers are rotatably installed in the casing, and the two flaking rollers are driven by a first driving device to rotate relative to each other, and a pressing hammer is vertically slidably installed above the symmetry line of the two flaking rollers in the casing, and the pressing hammer is driven by a second driving device to move vertically back and forth, and the lower end of the pressing hammer is a cone head, and a screening device for separating corn flakes and residue particles is provided in the casing below the two flaking rollers.

[0010] Preferably, the first driving device comprises two first motors, and the two first motors are respectively connected to the rotating shaft of a sheet pressing roller via a belt drive.

[0014] Preferably, a first closable cover is provided on the side wall of the chassis at the side of the pressing hammer, and a second closable cover is provided on the side wall on the same side at an angle below the sheet pressing roller.

[0015] Compared with the prior art, the present application provides a corn tablet pressing machine, which has the following beneficial effects:

[0016] When in use, the two flaking rollers rotate relative to each other to crush the corn into flakes, and at the same time, the pressing hammer moves vertically back and forth under the action of the second driving device. The pressing hammer moves downward to press the corn, and under the action of this pressure, the corn kernels gradually move between the two flaking rollers to prevent the corn kernels from being retained in the hopper; and when the pressing hammer moves upward, since the lower end of the pressing hammer is a cone head, like a scoop, the end surface of the cone head will give the corn kernels a tendency to lift up, preventing the corn kernels from being squeezed and making the lower layer hollow and unable to be discharged.

[0025] The following will be combined with the attached examples of the present application Figure 1-6 , the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0026] In order to solve the problems existing in the prior art, the present embodiment provides a corn flaking main machine, including a chassis 1 with openings at both the upper and lower ends, wherein two flaking rollers 2 are rotatably installed in the chassis 1, and the two flaking rollers 2 are driven by a first driving device to rotate relative to each other, and a pressing hammer 4 is vertically slidably installed above the symmetry line of the two flaking rollers 2 in the chassis, and the pressing hammer 4 is driven by a second driving device to move vertically back and forth, and the lower end of the pressing hammer 4 is a cone head, and a screening device for separating corn flakes and residue particles is provided in the chassis below the two flaking rollers 2.

[0027] Principle details of this embodiment:

[0028] A corn flake pressing machine comprises a chassis 1, wherein both upper and lower ends of the chassis 1 are open, and the upper end of the chassis 1 is connected to a feeding system for receiving steamed corn kernels; the lower end of the chassis 1 is open for dropping materials, and a conveyor belt is provided below to convey corn flakes;

[0029] Two flaking rollers 2 are rotatably installed in the chassis 1, and the two flaking rollers 2 are driven by the first driving device to rotate relative to each other. A gathering hopper 3 is provided above the two flaking rollers 2 in the chassis 1, which is used to gather materials at the symmetry line of the two flaking rollers 2. The outlet of the lower end of the gathering hopper 3 is located on the symmetry line of the two flaking rollers 2 and is against the surfaces of the two flaking rollers 2 to prevent corn kernels from leaking to the opposite side of the two flaking rollers 2; a scraper is provided in the chassis 1, which is against the surface of the flaking roller 2, and is used to scrape off corn sticking to the flaking roller 2; a pressure hammer 4 is vertically slidably installed above the symmetry line of the two flaking rollers 2 in the chassis, and the pressure hammer 4 is driven by the second driving device to move vertically back and forth, and the lower end of the pressure hammer 4 is a cone head.

[0030] When in use, the first driving device and the second driving device are started, the first driving device drives the two flaking rollers 2 to rotate relative to each other, and the second driving device drives the pressing hammer 4 to move back and forth vertically; corn kernels are put into the opening at the upper end of the chassis 1, and the corn kernels are drained into between the two gathering hoppers 3 under the action of the gathering hopper 3, and are crushed into sheets by the two relatively rotating flaking rollers 2, and then fall from the opening at the lower end of the chassis 1; at the same time, the pressing hammer 4 moves back and forth vertically, and the pressing hammer 4 moves downward to press the corn kernels, giving a pressure to the corn kernels accumulated between the two flaking rollers 2. Under the action of this pressure, the corn kernels gradually move between the two flaking rollers 2 and will not deviate, thereby preventing the corn kernels from being retained in the gathering hopper 3; and when the pressing hammer 4 moves upward, since the lower end of the pressing hammer 4 is a cone head, the pressing hammer 4 moves upward, and the end surface of the cone head will give the corn kernels an upward tendency, thereby preventing the corn kernels from being squeezed and making the lower layer hollow and unable to be discharged.

[0031] In a further embodiment of the present scheme, the first driving device includes two first motors, and the two first motors are respectively connected to the rotating shaft of a sheet pressing roller 2 via a belt drive, that is, the two sheet pressing rollers 2 are driven by independent power, which requires a power transmission mechanism such as gears to be combined with a single power. This method is not only simpler in structure, but also has no transmission and no wear of intermediate transmission parts; and the power is more sufficient.

[0032] In a further embodiment of the present solution, the second driving device includes a cam 5, which is driven by a second motor fixed to the outer wall of the chassis 1. The cam 5 is rotatably mounted in the chassis 1 and is located directly above the pressure hammer 4. A spring is provided between the pressure hammer 4 and the chassis 1, and multiple groups of springs are provided. The second motor is started to drive the cam 5 to rotate, and each time the cam 5 rotates one circle, it will press the pressure hammer 4 to move downward once, and when the cam 5 is separated from the pressure hammer 4, the pressure hammer 4 will be reset under the action of the spring, thereby realizing the vertical reciprocating movement of the pressure hammer 4.

[0033] In the embodiment, the structure capable of driving the pressure hammer 4 to move vertically back and forth also includes any device that can be used in the present device and can achieve vertical reciprocating movement, including but not limited to a hydraulic rod, an electric telescopic rod, and the like.

[0034] In a further embodiment of the present invention, a rotating shaft is rotatably mounted in the chassis 1 just above the pressure hammer 4, the rotating shaft is driven by a second motor, and a plurality of cams 5 are arranged at intervals on the rotating shaft. Since the pressure hammer 4 is adapted to the length of the chassis 1, a plurality of cams 5 are arranged so that the downward pressure force received by the pressure hammer 4 is more balanced, and the force is not offset or concentrated, which causes the pressure edge to deviate to one side, resulting in uneven downward pressure.

[0035] In a further embodiment of the present scheme, a sliding cavity 6 is provided in the box body above the symmetry line of the two sheet pressing rollers 2, and a through notch is provided on the upper and lower walls of the sliding cavity 6. The handle end of the pressure hammer 4 passes through the sliding cavity 6 from the notch, and the spring is arranged in the sliding cavity 6. The setting of the sliding cavity 6 provides an installation foundation for the vertical movement of the pressure hammer 4, cooperates with the cam 5 to limit the vertical movement distance of the pressure hammer 4; and covers the spring and other components to prevent corn kernels from penetrating into the spring and affecting the expansion and contraction of the spring, that is, a sealed installation is provided to prevent corn kernels from penetrating and affecting the stability of the vertical movement of the pressure hammer 4.

[0036] In a further embodiment of the present scheme, a first cover 7 which can be opened and closed is provided on the side wall of the chassis 1 at the side of the pressure hammer 4 for observation and cleaning in case of blockage;

[0037] The chassis 1 is provided with an openable and closable second cover 8 on the side wall on the same side as the first cover 7 and obliquely below the sheet pressing roller 2 for equipment maintenance.
