Description

Technical Field

[0001] The invention relates to the technical field of rapeseed oil pressing, and in particular to rapeseed oil pressing pretreatment equipment and a use method thereof. Background Art

[0002] Rapeseed oil extraction is a common vegetable oil extraction process, mainly using rapeseed as raw material. Rapeseed is rich in oil, usually with an oil content of between 35% and 45%. The oil extraction process mainly includes cleaning, crushing, steaming, flaking, pressing and other steps. After filtering and sedimentation, the extracted oil can be treated to obtain golden and nutritious rapeseed oil.

[0003] Before rapeseed oil is extracted, it is usually necessary to undergo flaking pretreatment to press the rapeseed into thin flakes, destroy its cell structure, and increase the surface area of ​​the oil to facilitate subsequent extraction.

[0004] The existing patent (publication number: CN220639010U) discloses a rapeseed oil processing embryo rolling machine, including a chassis, a material sprinkling box is fixedly connected to the top of the chassis, a material hopper is fixedly connected to the top of the material sprinkling box, and a vibration motor is fixedly connected to the outer surface of the material sprinkling box. It has the following advantages and effects: the material sprinkling box is fixed to the top of the chassis, and when the rapeseed is discharged through the material hopper, the vibration motor is started to drive the connecting rod and the sub-screen to vibrate, and a large amount of rapeseed falls to the upper surface of the sub-screen. The continuous vibration of the sub-screen causes the rapeseed to gradually fall into the extrusion gap between the two groups of embryo rolling rollers for extrusion, and the impurities on the blades retained on the surface of the sub-screen flow to the position of the discharge port with the vibration and are discharged through the guide hopper. In the above equipment, the rapeseed is rolled by the rolling rollers on both sides. However, most rapeseeds are spherical. When the rolling rollers are used for rolling, some rapeseeds will roll in the gap between the rolling rollers, which may cause the rapeseeds to move and cause poor rolling effect. It is usually necessary to soften the rapeseed to reduce its rolling property and increase its plasticity, which makes it difficult to use.

[0017] A method for using a rapeseed oil pressing pretreatment device comprises the following steps:

[0018] S1. Put the rapeseed to be rolled into the top buffer box, start the driving motor to drive the active dial and dial the driven groove wheel to realize intermittent rotation and rotate 90 degrees each time, the trigger arm rotates clockwise and when the contact wheel contacts the lifting bracket, it will lift it up, drive the lifting bracket and the lifting channel to rise, and squeeze the lifting reset spring to store force during the rising process. When the lifting channel rises to the top, the hammer input slot is in the top buffer box, and the rapeseed rolls from the top guide slot into the lifting channel to the inside of the hammer shell, and is dispersed to both sides through the inner mounting slot. After the dwell interval, the trigger arm continues to rotate, the contact wheel disengages from the lifting bracket, and the lifting reset spring resets to drive the lifting bracket to move downward quickly, and the hammer shell hits the rapeseed inside the embryo rolling cavity, realizing the slow rise and fast fall work process, and completing one cycle;

[0019] S2. When the hammer housing is slowly rising, the outer lifting block pulls the elastic rope, which is wound around the surface of the vibration block. After being pulled, the elastic rope drives the vibration block to rotate and rotates the vibration reset spring to store torque. When the hammer housing descends, the vibration reset spring resets and drives the vibration block to rotate rapidly to vibrate the embryo rolling cavity, so that the rapeseeds cached inside the embryo rolling cavity can be evenly spread inside to wait for the embryo rolling to be pressed down. The hammer housing descends rapidly and hits the surface of the rapeseeds. At this time, a part of the rapeseeds and steel balls are installed inside the hammer housing, which offset the reaction force generated by the impact when hammering downward, so that the hammer housing will not rebound after the hammering, so as to prevent multiple impacts during one fall from causing the rapeseeds that have been pressed into thin slices to break;

[0020] S3. During the lifting process of the hammer shell, the lifting block is driven to lift and lower through the hammer connecting platform and the driven push-pull rod. At the same time, the driven push-pull rod can move horizontally on the hammer connecting platform to drive the lifting block to move horizontally. When the lifting block slowly rises, the size of the trapezoidal area in contact with the bottom opening and closing plate will gradually increase, and the bottom opening and closing plate will be pushed to both sides. The rapeseed pressed into thin slices in the embryo rolling cavity falls into the output base and is output from the output slot. The bottom opening and closing plates are connected by an opening and closing reset spring. When moving to both sides, the opening and closing reset spring will be stretched to store force. The lifting block further rises until it is separated from the bottom opening and closing plate and no longer has the effect of stretching. The opening and closing reset spring drives the bottom opening and closing plate to reset, and the embryo rolling cavity is no longer connected to the output base. The lifting block After further rising, the fixed protrusion moves from the straight section on the protrusion slide to the oblique section. The fixed protrusion is fixed on the embryo rolling cavity and remains unchanged, pushing the lifting movable block outward and pulling the driven frame and the driven rack outward. At this time, the opening and closing inclined plate has risen with the hammer shell and can be opened to the bottom. The driven rack drives the driven gear and the active shaft to rotate, and rotates the shaft spring to store the torsion. Under the connection action of the reverse connecting rod, the driven shaft is driven to rotate and the opening and closing inclined plate is opened downward. The rapeseed cached inside the hammer shell falls into the embryo rolling cavity. The driven rack continues to move outward until it is disengaged from the driven gear. Under the action of the shaft spring, the driven gear drives the opening and closing inclined plate to reset and close again. The hammer shell continues to move to the top to store rapeseed inside again.

[0021] When the lifting block is lowered to the bottom, the bottom opening and closing plate is no longer in contact with the bottom trapezoidal area of ​​the lifting block, and the oblique push block pushes the lifting block toward the hammer housing, and the lifting block is stuck between the bottom opening and closing plates again. In this way, the bottom opening and closing plate always remains closed during the descent, and the driven push-pull rod is also pushed into the inside of the hammer housing. At this time, the bottom of the opening and closing inclined plate contacts the bottom opening and closing plate and cannot be opened to the bottom, and the driven rack cannot push the driven gear, which slides upward in the driven frame and slides away from the top of the driven gear.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In the present invention, the intermittent driving mechanism and the lifting hammer mechanism cooperate with each other, and the slow rising and fast falling movement process is realized through intermittent transmission and spring power storage. The hammer shell hits the rapeseed in the embryo rolling cavity to complete an embryo rolling action. The steel balls and rapeseed inside the hammer shell play a buffering role during the hammering process. The steel balls gather at the upper end of the hammer shell under the action of inertia, and disperse the impact force together with the rapeseed to prevent the hammer shell from rebounding due to the reaction force, thereby avoiding the rapeseed flakes from being broken by multiple knocks. The lifting hammer mechanism directly acts on the surface of the rapeseed, avoiding the problem of the rapeseed rolling in the gap, and will not leak out during the embryo rolling process, thereby improving the stability of the embryo rolling.

[0024] In the present invention, through the cooperation of the vibrating mechanism and the lifting hammer mechanism, when the hammer housing descends, the vibration reset spring releases energy, drives the vibration block to rotate rapidly, and generates vibration to act on the embryo rolling cavity. This vibration makes the rapeseed evenly spread in the embryo rolling cavity, providing better conditions for the next embryo rolling.

[0025] In the present invention, the opening and closing of the bottom of the embryo rolling cavity and the hammer shell are controlled by the cooperation of the opening and closing control mechanism, the hammer opening and closing mechanism and the lifting hammer mechanism to transport rapeseed, so that the hammer shell can not only play the role of embryo rolling, but also play the role of quantitatively transporting rapeseed each time, thereby realizing the automation of the entire embryo rolling process, reducing manual intervention and improving production efficiency.

Through the setting of the lifting hammer mechanism 5, during use, the lifting channel 55 is fixedly connected with a hammer housing 56. The channel 55 connects the hammer housing 56 and the lifting bracket 54, so that the hammer housing 56 can follow the lifting bracket 54 to rise and fall and receive the rapeseed in the lifting channel 55. The transparent window plate 562 is used to observe the rapeseed inside. The inner installation groove 57 and the steel ball 571 are located in the center of the hammer housing 56, and the top of the inner installation groove 57 is a pointed top, which can disperse the fallen rapeseed to both sides, and play the effect of balancing the weight on both sides.

The driven groove wheel 621 contacts the contact bevel block 642. One side of the contact bevel block 642 is an inclined surface and can be pressed down by the action of the anti-reverse spring 641. The driven groove wheel 621 can only press down the contact bevel block 642 to pass through when it rotates clockwise to prevent reversal. The trigger arm 63 and the driven groove wheel 621 are always in an inclined state when they cross. When the trigger arm 63 is at the top, it will be pressed down by the lifting bracket 54. At this time, the current state needs to be maintained. The lifting bracket 54 can only rotate counterclockwise when pressing down the trigger arm 63.

[0065] In this embodiment, Fig.16 As shown, the lifting movable block 82 descends to the bottom and is pushed into restoration by the oblique push block 841.

[0066] A method for using a rapeseed oil pressing pretreatment device comprises the following steps:

[0067] S1. Put the rapeseeds to be rolled into the top buffer box 3, start the driving motor 61 to drive the active dial 62 and toggle the driven groove wheel 621 to realize intermittent rotation and rotate ninety degrees each time, the trigger arm 63 rotates clockwise when the contact wheel 631 contacts the lifting bracket 54 to lift it up, drive the lifting bracket 54 and the lifting channel 55 to rise, and squeeze the lifting reset spring 531 to store force during the rising process, when the lifting channel 55 rises to the top, the hammer input groove 551 is in the top buffer box 3, the rapeseed rolls from the top guide groove 31 into the lifting channel 55 to the inside of the hammer shell 56, and is dispersed to both sides through the inner mounting groove 57, and after a stay interval, the trigger arm 63 continues to rotate, the contact wheel 631 is detached from the lifting bracket 54, the lifting reset spring 531 is reset to drive the lifting bracket 54 to move downward quickly, and the hammer shell 56 hits the rapeseed inside the embryo rolling cavity 2, realizing the slow rise and fast fall process, and completing a cycle;

[0068] S2, when the hammer housing 56 is slowly rising, the outer lifting block 561 pulls the elastic rope 73, which is wound around the surface of the vibration block 72. After being pulled, the vibration block 72 is driven to rotate and the vibration reset spring 711 is rotated to store torque. When the hammer housing 56 is lowered, the vibration reset spring 711 is reset to drive the vibration block 72 to rotate rapidly to vibrate the embryo rolling cavity 2, so that the rapeseeds cached inside the embryo rolling cavity 2 can be evenly spread inside to wait for embryo rolling. The hammer housing 56 is lowered rapidly and hits the surface of the rapeseeds. At this time, a part of the rapeseeds and the steel ball 571 are installed inside the hammer housing 56, which offset the reaction force generated by the impact when hammering downward, so that the hammer housing 56 will not rebound after the hammering, so as to prevent multiple impacts during one fall from causing the rapeseeds that have been pressed into thin slices to break;

[0069] S3. During the lifting process of the hammer housing 56, the lifting block 82 is driven to lift and lower through the hammer connecting platform 81 and the driven push-pull rod 811. At the same time, the driven push-pull rod 811 can move horizontally on the hammer connecting platform 81 to drive the lifting block 82 to move horizontally. When the lifting block 82 slowly rises, the size of the trapezoidal area in contact with the bottom opening and closing plate 83 will gradually increase, and the bottom opening and closing plate 83 will be pushed to both sides. The rapeseed pressed into thin slices in the embryo rolling cavity 2 falls into the output base 1 and is output from the output groove 11. The bottom opening and closing plates 83 are connected by an opening and closing reset spring 832. When moving to both sides, the opening and closing reset spring 832 will be stretched to store force, and the lifting block 82 will further rise until it is separated from the bottom opening and closing plate 83 and no longer has the effect of stretching. The opening and closing reset spring 832 drives the bottom opening and closing plate 83 to reset, and the embryo rolling cavity 2 is no longer connected with the output base 1. The lifting block 82 further rises After the hammer housing 56 is lifted, the fixed protrusion 821 moves from the straight line section on the protrusion slide 822 to the oblique line section. The fixed protrusion 821 is fixed on the embryo rolling cavity 2 and remains unchanged. The lifting movable block 82 is pushed outward and the driven frame 951 and the driven rack 95 are pulled outward. At this time, the opening and closing inclined plate 91 has risen with the hammer housing 56 and can be opened to the bottom. The driven rack 95 drives the driven gear 941 and the active shaft 94 to rotate, and the rotating shaft spring 921 is rotated to store the torque. Under the connection action of the reverse connecting rod 93, the driven shaft 92 is driven to rotate and the opening and closing inclined plate 91 is opened downward. The rapeseeds cached inside the hammer housing 56 fall into the embryo rolling cavity 2. The driven rack 95 continues to move outward until it is separated from the driven gear 941. The driven gear 941 drives the opening and closing inclined plate 91 to reset and close again under the action of the rotating shaft spring 921. The hammer housing 56 continues to move to the top to store rapeseeds inside again.

[0070] S4. When the hammer housing 56 descends, it will drive the lifting movable block 82 to descend. At this time, the lifting movable block 82 is still in a state of being pushed outward. When descending, the bottom trapezoidal area will not contact the bottom opening and closing plate 83, but will be clamped between the bottom opening and closing plate 83 and the oblique push block 841. The bottom opening and closing plate 83 still maintains a closed state, and after continuing to descend, it will contact the bottom inclined surface of the oblique push block 841, pushing the oblique push block 841 backward and compressing the push block return spring 842. However, at this time, the trapezoidal area of ​​the lifting movable block 82 is blocked by the bottom opening and closing plate 83 and cannot be pushed until the lifting movable block 82 descends to the lowest point. The bottom of the bottom opening and closing plate 83 is no longer in contact with the trapezoidal area at the bottom of the lifting movable block 82, and the inclined push block 841 pushes the lifting movable block 82 toward the hammer housing 56, and the lifting movable block 82 is again stuck between the bottom opening and closing plates 83, so that the bottom opening and closing plate 83 always remains in a closed state during the descent process, and the driven push-pull rod 811 is also pushed into the inside of the hammer housing 56. At this time, the bottom of the opening and closing inclined plate 91 is in contact with the bottom opening and closing plate 83 and cannot be opened to the bottom, and the driven rack 95 cannot push the driven gear 941, and slides upward in the driven frame 951 and slides away from the top of the driven gear 941.

When the contact wheel (631) contacts the lifting bracket (54), it will lift it up, drive the lifting bracket (54) and the lifting channel (55) to rise, and squeeze the lifting return spring (531) to accumulate force during the rising process. When the lifting channel (55) rises to the top, the hammer input slot (551) is in the top buffer box (3), the rapeseed rolls from the top guide groove (31) into the lifting channel (55) to the inside of the hammer shell (56), and is dispersed to both sides through the inner mounting groove (57).

After being pulled, the elastic rope (73) drives the vibration block (72) to rotate and rotate the vibration reset spring (711) to store torque. When the hammer housing (56) descends, the vibration reset spring (711) is reset and drives the vibration block (72) to rotate rapidly to generate vibration on the embryo rolling cavity (2), so that the rapeseeds cached inside the embryo rolling cavity (2) can be evenly spread inside to wait for the embryo rolling to be pressed down. The hammer housing (56) descends rapidly and hits the surface of the rapeseeds. At this time, a part of the rapeseeds and steel balls (571) are contained inside the hammer housing (56), which offset the reaction force generated by the impact when hammering downward, so that the hammer housing (56) will not rebound after the descending hammering, thereby preventing multiple impacts during one fall from causing the rapeseeds that have been pressed into thin slices to break; S3. During the lifting process of the hammer housing (56), the lifting movable block (82) is driven to lift and lower through the hammer connecting platform (81) and the driven push-pull rod (811).

The bottom opening and closing plates (83) are connected by an opening and closing reset spring (832). When moving to both sides, the opening and closing reset spring (832) is stretched to store force, and the lifting movable block (82) rises further until it is separated from the bottom opening and closing plate (83) and no longer has the effect of stretching. The opening and closing reset spring (832) drives the bottom opening and closing plate (83) to reset, and the embryo rolling cavity (2) is no longer connected to the output base (1). The lifting movable block (82) rises further. After that, the fixed protrusion (821) moves from the straight line section on the protrusion slide groove (822) to the oblique line section, and the fixed protrusion (821) is fixed on the embryo rolling cavity (2) and remains unchanged, which pushes the lifting movable block (82) outward and pulls the driven frame (951) and the driven rack (95) outward. At this time, the opening and closing inclined plate (91) has risen with the hammer housing (56) and can be opened to the bottom. The driven rack (95) drives the driven gear (941) and the driving shaft (94) to rotate, and the rotating shaft spring (92 1) The torque is stored, and the driven rotating shaft (92) is driven to rotate under the connection of the reverse connecting rod (93) to open the opening and closing inclined plate (91) downward, and the rapeseeds cached inside the hammer housing (56) fall into the embryo rolling chamber (2), and the driven rack (95) continues to move outward until it is separated from the driven gear (941), and the driven gear (941) drives the opening and closing inclined plate (91) to reset and close again under the action of the rotating shaft spring (921), and the hammer housing (56) continues to move to the top to store rapeseeds inside again; S4.

When descending, the bottom trapezoidal area will not contact the bottom opening and closing plate (83), but will be clamped between the bottom opening and closing plate (83) and the inclined push block (841). The bottom opening and closing plate (83) still maintains a closed state, and after continuing to descend, it contacts the bottom inclined surface of the inclined push block (841), pushing the inclined push block (841) backward and compressing the push block return spring (842). However, at this time, the trapezoidal area of ​​the lifting movable block (82) is blocked by the bottom opening and closing plate (83) and cannot be pushed until the lifting movable block (82) descends to the bottom. At this time, the bottom opening and closing plate (83) no longer contacts the trapezoidal area at the bottom of the lifting movable block (82), and the inclined push block (841) pushes the lifting movable block (82) toward the hammer housing (56), and the lifting movable block (82) is again inserted between the bottom opening and closing plates (83), so that the bottom opening and closing plates (83) always remain in a closed state during the descending process, and the driven push-pull rod (811) is also pushed into the inside of the hammer housing (56).
