Description

Technical Field

[0001] This invention relates to a device for grating the peel of unripe Torreya grandis fruit. Background Technology

[0002] Torreya nuts are a popular type of nut, but their processing is quite complicated, with the most difficult part being peeling off the green husks. Currently, peeling unripe torreya nuts is still done by hand, which is inefficient and costly. Especially when purchasing large quantities, the slow process of manual peeling leads to many torreya nuts rotting and being discarded.

[0003] To improve the peeling efficiency of unripe torreya nuts, semi-automatic torreya nut peelers have appeared on the market. However, these peelers have defects: during the impact peeling process, the disordered impact force can damage the kernels of the torreya nuts, causing the kernels to be eroded by rotten bacteria during the composting process, affecting the flavor and quality of the torreya nuts. In fact, the toxic substances in them may even affect human health.

[0004] Utility model patent application number 202220954104.6 discloses a "Peeling Mechanism for Torreya grandis," which uses a pair of parallel peeling rollers to squeeze and peel the unripe Torreya grandis fruit. The distance between the peeling rollers is greater than the size of the kernel but smaller than the size of the unripe Torreya grandis fruit. This Torreya grandis peeling mechanism still has the following drawbacks: First, the distance between the peeling rollers is unsuitable for both large and small unripe Torreya grandis fruit; the kernels of larger unripe Torreya grandis fruit will be crushed by the peeling rollers, while the green skin of smaller unripe Torreya grandis fruit cannot be peeled off. Second, peeling the green skin of unripe Torreya grandis fruit by squeezing with the peeling rollers not only causes varying degrees of damage to the kernels but also results in incomplete peeling. Third, it can only be used for Torreya grandis fruit whose outer skin is already ripe and is not suitable for unripe Torreya grandis fruit. Summary of the Invention

[0005] The purpose of this invention is to provide a peeling device for unripe Torreya nuts, suitable for peeling immature Torreya nuts, especially for Torreya nuts where the peel and kernel are tightly adhered, and also suitable for peeling ripe Torreya nuts. In particular, using the rotary Torreya nut peeling machine of this invention to peel Torreya nuts will not cause the kernel to break, and it helps to protect the two ends of the Torreya nuts, ensuring the integrity of the kernel and facilitating subsequent fermentation.

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

[0007] A peeling device for unripe Torreya nuts includes: a Torreya nut clamping and rotating device for holding the unripe Torreya nuts and a Torreya nut flexible peeling device for wiping off the unripe husks. The Torreya nut clamping and rotating device includes: a guide positioner disposed on a rotating shaft for circumferentially protecting the unripe Torreya nuts and keeping them upright in the initial state; a lower pressure head for supporting the lower end of the unripe Torreya nuts below the guide positioner; and an upper pressure head for pressing down the upper end of the unripe Torreya nuts above the guide positioner. The guide positioner includes an arc-shaped bending plate, the inner wall of which is flush with... There are gaps between the unripe Torreya nuts. The opening of the arc-shaped bent plate faces the flexible peeling device for the unripe Torreya nuts. The size of the opening is smaller than the diameter of the middle part of the unripe Torreya nut. The upper pressure head is rotatably mounted on the inner end of the pressure head rotating disk via an upper support bearing. The outer end of the pressure head rotating disk is located on the upper end of the rotating disk upright. The lower end of the rotating disk upright abuts against the lifting cam via an upright drive wheel. The lower pressure head is mounted on the lower bearing seat via a lower support bearing. The lower end of the lower pressure head meshes with a rolling rack via a rotation drive gear. The flexible peeling device for the unripe Torreya nuts includes: a support for the peeler. A scouring pad is mounted on a shaft, and a scouring pad rotation driver, mounted on a scouring wheel support, drives the scouring pad to rotate via a pulley drive mechanism. The scouring pad support shaft is located below the cantilever of the scouring wheel support. The scouring pad has a feed drive assembly, which includes: a drive shaft base, a drive shaft sliding sleeve, a control lever driver, a first buffer pad, a return spring, a scouring drive shaft, a second buffer pad, and a positioning sliding sleeve. The control lever driver is fixed to the drive shaft base and controls the forward and reverse movement of the drive shaft control lever via forward and reverse rotation. The drive shaft control lever is connected to the first buffer pad. The first buffer pad is in contact with the outer end face of the rubbing drive shaft. The rubbing drive shaft is slidably sleeved in the hole of the drive shaft sliding sleeve. The inner end of the return spring is in contact with the outer end face of the drive shaft sliding sleeve. The outer end of the return spring is in contact with the inner end face of the outer end plate of the rubbing drive shaft. The second buffer pad is set between the inner end face of the rubbing drive shaft and the rubbing wheel support seat. The outer ring of the positioning sliding sleeve is sleeved in the outer inner ring of the rubbing wheel support seat and is fixed to the rubbing wheel support seat. The inner ring of the positioning sliding sleeve is slidably engaged with the inner outer ring of the rubbing drive shaft. The rubbing wheel support seat is supported on the rubbing drive shaft by the positioning sliding sleeve.

[0008] A rotating sleeve for the grater is provided between the grater and the grater support shaft. The outer periphery of the grater has multiple friction blades, and the cutting edges of the friction blades are arc-shaped.

[0009] The leather polisher has a leather polishing reversing assembly, which includes: a leather polisher reversing driver, a sliding sleeve, a leather polishing wheel support, and a drive shaft base. The inner ring of the leather polisher reversing driver is connected to the leather polishing wheel support, the upper side of the sliding sleeve is connected to the drive shaft base, and the lower side of the sliding sleeve is connected to the outer ring of the leather polisher reversing driver. This allows the upper and lower sides of the sliding sleeve to absorb the displacement generated between the leather polishing wheel support and the drive shaft base during the feed drive by sliding on the sliding positioning surface. Furthermore, the sliding positioning surface acts as an anti-rotation surface to prevent the outer ring of the leather polisher reversing driver from generating circumferential relative movement with the drive shaft base.

[0010] The peeler has a centering and lifting assembly, which includes: a rack mounting bracket, a centering and lifting rack, a centering and lifting drive gear, a drive shaft base, a connecting seat, a lifting driver, a lifting drive wheel, a right drive wheel, a left drive wheel, a right drive shaft, and a left drive shaft. The centering and lifting rack is arc-shaped, and the arc is the average of the arc of multiple Torreya nuts. The centering and lifting rack includes a rear centering and lifting rack and a front centering and lifting rack. The centering and lifting drive gear includes a right rear lifting gear and a left rear lifting gear. The wheel, left front lifting gear, right front lifting gear, rear centering lifting rack and front centering lifting rack are fixedly connected to both sides of the rack mounting bracket. The connecting seat connects the right drive shaft and left drive shaft to the drive shaft base as one unit, and the right drive shaft and left drive shaft can rotate circumferentially in the connecting hole of the connecting seat. The right rear lifting gear and left rear lifting gear are respectively placed on both sides of the rear centering lifting rack and are both engaged with the rear centering lifting rack. The left front lifting gear and right front lifting gear are respectively placed on both sides of the front centering lifting rack and are both engaged with the front centering lifting rack.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: Using the above technical solution, the unripe Torreya nuts are fed into the Torreya nut clamping and rotating device. This device can circumferentially protect the unripe Torreya nuts and keep them upright and rotating in the initial state. The flexible peeling device of the Torreya nut flexible peeling device is driven to rotate via a belt pulley drive mechanism, thus removing the green skin from the outer periphery of the Torreya nut. This structure utilizes rotational friction to remove the green skin of the Torreya nut, avoiding the defect of crushing the Torreya nut kernel. It is suitable for peeling immature Torreya nuts, especially for Torreya nuts where the green skin and kernel are tightly adhered, and also suitable for peeling mature Torreya nuts; because the fragrance... The upper and lower skins of the unripe torreya nuts are held down by the upper and lower pressure heads respectively, preventing the peeler from removing them. This effectively protects the "eyes" at both ends of the torreya nut, ensuring the integrity of the kernel and facilitating subsequent fermentation. The peeler features a feed drive assembly that allows for flexible control of the peeling feed, improving the peeling effect. The first and second double buffer pads prevent excessive pressure on the unripe torreya nuts during peeling. When excessive pressure occurs, the first and second buffer pads absorb the displacement caused by the flexible peeling device retracting through double deformation, further protecting the kernel from being scratched. A further beneficial effect is that the peeler includes a peeling reversing assembly and a centering lifting assembly, allowing for flexible control of the peeling angle and further improving the peeling effect.

[0041] Preferably, the scouring pad 201 has a feed drive assembly, which includes: a drive shaft base 214, a drive shaft sliding sleeve 215, a control lever driver 213, a first buffer pad 211, a return spring 210, a scouring drive shaft 209, a second buffer pad 207, and a positioning sliding sleeve 206.

The sliding sleeve 210 is slidably installed in the hole of the sliding sleeve 215 of the drive shaft. The inner end of the return spring 210 contacts the outer end face of the sliding sleeve 215 of the drive shaft. The outer end of the return spring 210 contacts the inner end face of the outer end plate of the rubbing drive shaft 209. The second buffer pad 207 is disposed between the inner end face of the rubbing drive shaft 209 and the rubbing wheel support seat 219. The outer ring of the positioning sliding sleeve 206 is sleeved in the outer inner ring of the rubbing wheel support seat 219 and is fixedly fitted on the rubbing wheel support seat 219.

The inner ring of the control lever driver 213 can be configured as a turbine, and the drive shaft control lever 212 can be configured as a worm. When the feed drive assembly is working, the control lever driver 213 rotates forward, and through the action of the worm gear, it drives the drive shaft control lever 212 to move forward. The drive shaft control lever 212 pushes the rubbing drive shaft 209 forward through the first buffer pad 211. At this time, the force of the forward movement is greater than the spring force of the return spring 210, and the return spring 210 is compressed. The rubbing drive shaft 209 continues to move forward, and pushes the rubbing wheel support seat 219 forward through the second buffer pad 207, thereby pushing the flexible rubbing device 2 for green torreya nuts to move forward. During retraction, the control lever driver 213 reverses, causing the drive shaft control lever 212 and the first buffer pad 211 to move backward together. At this moment, the first buffer pad 211 disengages from the rubbing drive shaft 209. Under the action of the return spring 210, the return spring 210 pushes the rubbing drive shaft 209 backward. The rubbing drive shaft 209 drives the rubbing wheel support seat 219 backward through the left inner end face, completing the retraction movement. During feeding, when the rubbing load end is too large, a backward thrust will be generated. When the backward thrust is applied, the second buffer pad 207 first deforms, absorbing the displacement generated by the backward thrust, causing the flexible rubbing device 2 for green Torreya nuts to retract backward, protecting the Torreya nuts from damage. When the backward thrust continues to increase, the first buffer pad 211 deforms, absorbing the displacement generated by the backward thrust, causing the flexible rubbing device 2 for green Torreya nuts to retract backward again, protecting the Torreya nuts from damage. Preferably, both the first buffer pad 211 and the second buffer pad 207 are made of soft rubber or silicone.

[0042] Preferably, the leather polisher 201 has a leather polishing reversing assembly, which includes: a leather polisher reversing driver 205, a sliding sleeve 208, a leather polishing wheel support 219, and a drive shaft base 214.

The upper side 20801 and lower side 20802 of the sliding sleeve slide on the sliding positioning surface 20803 to absorb the displacement generated between the rubbing wheel support 219 and the drive shaft base 214 during the feed drive. The sliding positioning surface 20803 also acts as an anti-rotation surface to prevent circumferential relative movement between the outer ring of the rubbing tool reversing driver 205 and the drive shaft base 214. The sliding positioning surface 20803 can be a vertical surface or an angled inclined surface. During operation, the rubbing tool reversing driver 205 is energized and rotates. The outer ring is connected to the drive shaft base 214 and remains circumferentially stationary. The inner ring rotates, driving the rubbing wheel support 219 to rotate and reverse, thus realizing the reversal of the flexible rubbing device 2 for nutmeg.

[0043] Preferably, the peeler 201 has a centering and lifting assembly, which includes: a rack mounting bracket 218, a centering and lifting rack 217, a centering and lifting drive gear 216, a drive shaft base 214, a connecting seat 228, a lifting driver 227, a lifting drive wheel 225, a right drive wheel 22401, a left drive wheel 22402, a right drive shaft 22601, and a left drive shaft 22602.

Connecting seat 228 connects right drive shaft 22601, left drive shaft 22602 and drive shaft base 214 into one unit, and right drive shaft 22601 and left drive shaft 22602 can rotate circumferentially in the connecting hole of connecting seat 228. Right rear lifting gear 21601 and left rear lifting gear 21602 are respectively placed on both sides of rear centering lifting rack 21701 and both mesh with rear centering lifting rack 21701. Left front lifting gear 21603 and right front lifting gear 21604 are respectively placed on both sides of front centering lifting rack 21702 and both mesh with front centering lifting rack 21702. During operation, the lifting drive 227 rotates, causing the lifting drive wheel 225 to rotate. The lifting drive wheel 225 drives the right drive wheel 22401 and the left drive wheel 22402 to rotate, which in turn drives the right drive shaft 22601 and the left drive shaft 22602 to rotate synchronously. The right drive shaft 22601 drives the right rear lifting gear 21601 and the right front lifting gear 21604 at both ends of it to rotate synchronously. The left drive shaft 22602 drives the left rear lifting gear 21602 and the left front lifting gear 21603 to rotate synchronously. The right rear lifting gear 21601 and the left rear lifting gear 21602 mesh with the rear centering lifting rack 21701, and the left front lifting gear 21603 and the right front lifting gear 21604 mesh with the front centering lifting rack 21702, which drive the right drive shaft 22601, the left drive shaft 22602 and the connecting seat 228 to move up and down, thereby driving the drive shaft base 214 to move up and down. The centering lifting rack 217 is set in an arc shape, so it can realize the centering lifting motion of the drive shaft base 214.

[0044] Preferably, the unripe Torreya nuts 100 to be peeled can be graded according to size. Different sizes of the unripe Torreya nuts 100 (preferably large, medium, and small grades) can be fitted with appropriate accessories such as a feeder 4, a distribution device 13, a guide positioner 103 (including an arc-shaped bending plate 103-1), and a peeler 201. For the same grade of unripe Torreya nuts 100, multiple nuts can be selected for measurement. The average value of the calculated outer curvature and middle diameter is used as the standard value for the outer curvature and middle diameter of that grade of unripe Torreya nuts 100. Based on these standard values, the corresponding dimensions of the feeder 4, distribution device 13, guide positioner 103 (including an arc-shaped bending plate 103-1), and peeler 201 are determined.

[0045] Preferably, the rotary table 3 is divided into a receiving area A, a middle peeling area B, a lower peeling area C, an upper peeling area D, a retraction area E, a discharge area F, and a reset adjustment area G in a counterclockwise direction starting from the discharge device 4. A peel and residue collection trough 9 is provided below the middle peeling area B, the lower peeling area C, and the upper peeling area D of the rotary table 3. A peel and residue discharge device 12 is provided at the lower part of the peel and residue collection trough 9. A torreya nut collection trough 10 is provided below the discharge area F of the rotary table 3. A torreya nut discharge device 11 is provided at the bottom of the torreya nut collection trough 10.

[0046] In receiving area A: the unripe Torreya nuts 100 in the hopper 5 enter the distributing device 13 through the discharger 4. The distributing device 13 sends the single upright unripe Torreya nuts 100 into the Torreya nut clamping and rotating device 1 below it. The corresponding upper pressure head 114 and lower pressure head 105 clamp the unripe Torreya nuts 100. The rotary gear 8 drives the rotary spindle 6 to rotate, thereby driving the rotary table 3 to rotate.

[0047] In the intermediate peeling zone B: The rotating turntable 3 feeds the green Torreya nuts 100 into the intermediate peeling zone B. The flexible peeling device 2 for the green Torreya nuts moves forward under the action of the feed drive assembly. At the same time, the green Torreya nuts 100 rotate under the action of the drive gear 112. The rotating peeler 201 contacts the rotating green Torreya nuts 100 to complete the intermediate peeling of the green Torreya nuts. After the intermediate peeling is completed, the flexible peeling device 2 for the green Torreya nuts retracts under the action of the feed drive assembly. The peel residue of the green Torreya nuts is sent out of the machine through the peel residue collection trough 9 and the peel residue discharger 12.

[0048] In the lower peeling zone C: The rotating turntable 3 feeds the unripe Torreya grandis fruit 100 with the middle peel removed into the lower peeling zone C. The centering and lifting component moves downward, so that the flexible peeling device 2 of the unripe Torreya grandis fruit is angled upward and aligned with the lower section of the unripe Torreya grandis fruit 100. The flexible peeling device 2 of the unripe Torreya grandis fruit moves towards the lower section of the unripe Torreya grandis fruit 100 under the action of the feed drive component. At the same time, the unripe Torreya grandis fruit rotates under the action of the drive gear 112. The rotating peeler 201 contacts the rotating unripe Torreya grandis fruit 100, completing the lower section peeling of the unripe Torreya grandis fruit. After the lower section peeling is completed, the flexible peeling device 2 of the unripe Torreya grandis fruit retracts under the action of the feed drive component. The peel residue of the unripe Torreya grandis fruit is sent out of the machine through the peel residue collection trough 9 and the peel residue discharger 12.

[0049] In the upper grating zone D: The rotating turntable 3 feeds the unripe Torreya nuts 100, with the middle and lower sections of the peel removed, into the upper grating zone D. The centering and lifting assembly moves upward, and simultaneously, under the action of the grating reversing assembly, the grating wheel support 219 rotates 180 degrees. Subsequently, the flexible grating device 2 for unripe Torreya nuts moves forward under the action of the feed drive assembly. At the same time, the unripe Torreya nuts rotate under the action of the drive gear 112. The rotating grater 201 and the rotating... The upper part of the green torreya nuts 100 is rubbed into contact with the nuts, and the flexible rubbing device 2, which has completed the upper part rubbing, moves backward under the action of the feed drive component. After the green torreya nuts are rubbed, the upper end skin 1001 and the lower end skin 1002 of the green torreya nuts remain on the nuts, which helps to protect the two ends of the nuts and facilitates the later fermentation. The nut residue is sent out of the machine through the residue collection trough 9 and the residue discharge device 12.

[0050] In the withdrawal zone E: The rotating turntable 3 sends the unripe Torreya grandis fruit 100 with the middle, lower and upper sections of the peel removed into the withdrawal zone E. The lifting cam 110 drives the rotating turntable upright 102 to move upward, and finally drives the upper pressure head 114 to move upward. At the same time, the steering support shaft 10201 fixed on the rotating turntable upright 102 slides in the inclined groove 10401 of the base 104, so that the upper pressure head rotating turntable 101 rotates by a preset angle, so that the center of the upper pressure head 114 separates from the center of the guide locator 103, so that the upper end of the unripe Torreya grandis fruit becomes free and can be discharged. In this state, the next unripe Torreya grandis fruit 100 can enter smoothly. Since the withdrawal zone E is small, when the center of the upper pressure head 114 separates from the center of the guide locator 103, the corresponding unripe Torreya grandis fruit peeling device has entered the discharge zone F, so as to ensure that the unripe Torreya grandis fruit 100 can only fall into the discharge zone F.

[0051] In discharge zone F: When the rotating turntable 3 feeds the unripe Torreya nuts 100 into discharge zone F, the upper pressure head 114 has already separated from the upper end of the unripe Torreya nuts 100. The guide positioner 103 rotates by a preset angle so that the unripe Torreya nuts 100 slide out in an inclined state (at this time, the maximum diameter of the middle part of the kernel of the unripe Torreya nuts 100 is smaller than the size of the opening 103-2). The unripe Torreya nuts 100 are sent out of the machine through the Torreya nut collection trough 10 and the Torreya nut discharger 11. To ensure that the Torreya nuts slide out smoothly, the guide positioner 103 can rotate at multiple angles. Figure 18 When the guide locator 103 is rotated to the left, the guide locator 103 can also be rotated to the right to pour out the Torreya nuts, or the guide locator 103 can rotate to the left and to the right in combination to pour out the Torreya nuts.

[0052] In the reset and adjustment zone G: the rotating turntable 3 sends the discharged torreya nuts clamping and rotating device 1 into the reset and adjustment zone G, the guide positioner 103 returns to its original position, and the cleaning device removes the residue of the previous torreya nut, waiting for the next torreya nut to enter. After entering the receiving area, the above steps are repeated.

[0053] The above describes the working process of a Torreya grandis fruit clamping and rotating device 1. All Torreya grandis fruit grating devices 1, evenly distributed around the edge of the rotary table 3, operate in the same way to achieve continuous, fully automated grating of the Torreya grandis fruit. Of course, the rotary Torreya grandis fruit grating machine of the present invention also has a control device for controlling the actions of the Torreya grandis fruit clamping and rotating device 1, the control lever driver 213, the lifting driver 227, the rotary gear 8, the material distribution device 13, the L-shaped baffle plate 1301, the L-shaped discharge plate 1302, etc. These controls are all mature technologies in the field and will not be elaborated upon here. This embodiment of the rotary torreya nut peeling machine has multiple torreya nut peeling devices evenly distributed around the edge of its rotating disc. A feeding device automatically feeds individual torreya nuts to be peeled into each torreya nut clamping and rotating device. These devices circumferentially protect the torreya nuts, keeping them upright and rotating initially. A belt pulley drive mechanism drives the flexible peeling device to rotate, thus removing the green skin from the torreya nuts. This structure utilizes rotational friction to remove the green husk of the Torreya grandis fruit, avoiding the defect of crushing the kernel. It is suitable for grating immature Torreya grandis fruits, especially those where the husk and kernel are tightly adhered, and also suitable for grating mature fruits. Because the upper and lower husks of the Torreya grandis fruit are pressed down by the upper and lower pressure heads respectively, the grater will not remove the upper and lower husks, thus perfectly protecting the "eyes" at both ends of the Torreya grandis fruit, ensuring the integrity of the kernel, and facilitating the later fermentation of the Torreya grandis. Further beneficial effects include: the peeler has the aforementioned feed drive assembly, peeling reversing assembly, and centering lifting assembly, which can flexibly control the peeling feed amount and peeling angle, further improving the peeling effect; the setting of the first and second double buffer pads can control the pressure applied to the green torreya nuts by the peeler during peeling to prevent it from being too high. When the pressure is too high, the first and second buffer pads can absorb the displacement caused by the retraction of the flexible peeling device of the green torreya nuts through double deformation, better protecting the torreya nuts from being scratched by the peeler.
