Description

Technical Field

[0001] This invention relates to the field of nut processing and peeling technology, specifically to an automatic peeling device and method with high-pressure water jet. Background Technology

[0002] Currently, the common method for removing nuts (mainly chestnuts) is to make incisions manually or mechanically and then roast or bake them. The shell expands when heated, but the shell still covers the kernel, so the kernel needs to be peeled manually.

[0003] Existing equipment uses multiple rubber rollers to rub and peel the kernels. After being exposed to high temperatures, most of the peels are carbonized. After being rubbed by multiple counter-rotating rubber rollers, most of the peels can be removed, with a peeling rate of generally over 85%. However, the efficiency is still relatively low, and a lot of manual trimming or other processing is still required in the later stages. Secondly, during the rubbing and peeling process, some kernels (mainly chestnuts) are easily crushed. The broken kernel rate after the rubbing and peeling process is generally at least 5%.

[0004] In view of the above-mentioned technical defects of the existing process and the improvement technology of high-pressure water jet, an automatic peeling device and method with high-pressure water jet is developed. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic peeling device and method with high-pressure water jet. When the V-shaped clamping groove is concave, high-pressure washing effectively removes the residual inner skin attached to the kernel. When switching to the inverted V-slope, the forward-leaning nuts will roll down along the convex inverted V-slope to achieve step-by-step feeding of materials. This cycle allows the nuts to be continuously turned over during the feeding process, achieving multiple high-pressure impacts of turning over in several V-shaped clamping grooves, which greatly improves the peeling rate.

[0015] A method for automatic peeling with high-pressure water jet, using the aforementioned automatic peeling device with high-pressure water jet, the peeling method comprising:

[0016] S1: Nuts enter the recessed V-shaped clamping groove. The nuts are placed at an angle under the support of the two limiting strips and are positioned above the linear high-pressure water jet assembly. The washing belt causes the limiting strips on both sides to be recessed and clamp the material. The greater the recess of the V-shaped clamping groove, the greater the clamping force. In conjunction with the action of the linear high-pressure water jet assembly, the bottom linear high-pressure water jet assembly sprays several materials on the lower surface to perform a peeling action.

[0017] S2: When the V-shaped clamping groove reverses and switches to the upper convex inverted V slope, the forward-leaning nuts will roll down along the upper convex inverted V slope to achieve material feeding in stages. This cycle continues, and with the continuous tumbling of the nuts during the feeding process, the high-pressure impact effect of multiple tumbling is achieved in several V-shaped clamping grooves.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This invention utilizes the combination of a stepped transmission frame and a V-shaped connecting rod structure. When the V-shaped groove is recessed, the washing belt drives the limiting strips on both sides to be recessed and clamp the material. The greater the degree of recess in the V-shaped groove, the greater the clamping force. Combined with the action of the linear high-pressure water jet component, the bottom linear high-pressure water jet component sprays onto the lower surface of several materials, providing an upward impact force. The limiting strips on both sides of the V-shaped groove clamp onto the outer wall of the nut. At this time, under the action of water pressure, the two limiting strips indirectly provide a reverse frictional force to the outer wall of the nut, thereby effectively removing the residual inner skin attached to the kernel.

[0020] 2. In this invention, when the V-shaped clamping groove reverses and switches to the upper convex inverted V-slope, the forward-leaning nuts will roll down along the upper convex inverted V-slope to achieve material feeding in stages. This cycle continues, and with the continuous tumbling of the nuts during the feeding process, the high-pressure impact effect of multiple tumbling is achieved in several V-shaped clamping grooves, which greatly improves the peeling rate.

[0021] 3. As another embodiment of the present invention, a hood-type high-pressure water jet assembly is provided, which can further improve the aforementioned linear high-pressure water jet assembly. The linear high-pressure nozzle at the inner edge of the hood can perform oscillating linear jetting to spray in a multi-angle coverage manner, while the spray plate in the middle performs cleaning spraying, further improving the peeling and cleaning degree of nuts.

[0043] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. The various embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0044] Example 1

[0045] Please see Figures 1 to 15The present invention preferably provides the following technical solution: an automatic peeling device with high-pressure water jet, comprising: a base plate 111; a stepped transmission frame disposed on the base plate 111; a V-shaped connecting rod structure mounted on the top of the stepped transmission frame; and a cleaning belt 826 connected to the V-shaped connecting rod structure, wherein the cleaning belt 826 can form a plurality of continuously concave V-shaped grooves and convex inverted V-shaped slopes on the V-shaped connecting rod structure; and limiting strips 825 fixed on both sides of the V-shaped grooves, wherein the setting height of the limiting strip 825 on the side closer to the first end of the cleaning belt 826 is greater than that on the other side. The height of the 825 limit bar, with the two 825 limit bars working together in the V-shaped clamping groove, can be used to support the lower surface of several materials arranged linearly; the bottom of the concave V-shaped clamping groove is also equipped with a linear high-pressure water jet assembly. When the stepped transmission frame drives the V-shaped connecting rod structure to run dynamically, when the V-shaped clamping groove is running in the concave direction, the cleaning belt 826 drives the limit bars 825 on both sides to be concave and clamp the materials. The linear high-pressure water jet assembly is used for spraying and peeling several materials. When the V-shaped clamping groove runs in the reverse direction and switches to the convex inverted V-slope, it is used for the material to be fed step by step and to perform tumbling.

[0046] In this application, the nuts, primarily chestnuts, are roasted or traditionally stir-fried at high temperatures. The chestnut skin expands due to the heat, and then a high-pressure, high-temperature water jet is used to sweep and brush them. The nuts tumble and vibrate with the sprayed high-pressure water, effectively removing any remaining inner skin adhering to the kernel. Preferably, such as... Figure 1 , 6 As shown in Figure 8, the washing belt 826 is equipped with filter holes for the discharge of high-pressure water flow, and preferably uses hot water at 80-90 degrees Celsius as the spray water source, which can prevent the growth of bacteria in the water source, enhance the removal effect, and obtain chestnut kernels that meet the quality requirements of subsequent processing.

[0047] In terms of device structure, through the cooperation of the stepped transmission frame and the V-shaped connecting rod structure, the washing belt 826 can form several continuous concave V-shaped clamping grooves and convex inverted V-shaped slopes. The first end of the device can connect to the long trough-shaped nut discharge trough, and the nut materials enter the concave V-shaped clamping grooves, such as... Figure 6 , 9 Nuts 9 and 11 are linearly distributed within a concave V-shaped groove. Supported by two limiting strips 825, the nuts are placed at a slight angle above the linear high-pressure water jet assembly. The stepped transmission frame drives the V-shaped connecting rod structure to dynamically operate, achieving the concave movement of the V-shaped groove. Figure 11 As shown, the washing belt 826 drives the limiting strips 825 on both sides to be recessed and clamp the material. The greater the concavity of the V-shaped groove, the greater the clamping force. With the help of the linear high-pressure water jet component, the linear high-pressure water jet component at the bottom sprays several materials onto the lower surface, providing an upward impact force. The limiting strips 825 on both sides of the V-shaped groove clamp the outer wall of the nut. At this time, under the action of water pressure, the two limiting strips 825 indirectly provide a reverse friction force to the outer wall of the nut, thereby effectively removing the residual inner skin attached to the kernel.

[0048] like Figure 11 As shown, because the height of the limiting strip 825 on one side near the beginning of the washing belt 826 is greater than the height of the limiting strip 825 on the other side, the nuts placed on the two limiting strips 825 tend to lean forward. When the V-shaped clamping groove reverses and switches to the upper convex inverted V slope, the forward-leaning nuts will roll down along the upper convex inverted V slope to achieve material feeding in stages. This cycle continues, and with the continuous tumbling of the nuts during the feeding process, the high-pressure impact effect of multiple tumbling is achieved in several V-shaped clamping grooves, which greatly improves the peeling rate.

[0049] Another implementation of this structure can be applied to nuts with slits, mainly chestnuts. After being roasted or traditionally stir-fried at high temperatures, the chestnut shell expands due to heat, creating a slit of a certain width at the slit in the chestnut skin. The shell still covers the kernel. The high-pressure water jet creates a certain amount of compression and expansion between the shell and the kernel, pushing the shell apart and separating them, thus removing the shell and achieving the desired kernel removal effect. Similarly, the limiting strips 825 on both sides of the V-shaped clamping groove clamp the outer wall of the nut. When the slit of a certain width is located above the linear high-pressure water jet assembly, the above process can be achieved. Multiple high-pressure impacts are achieved within several V-shaped clamping grooves, significantly improving the shelling rate of the slit nuts.

[0050] Furthermore, the cross-section of the limiting strip 825 is ear-shaped, such as... Figure 11 As shown, through the structural design of the limiting strip 825, when the V-shaped clamping groove continues to be recessed, the shape of the limiting strip 825 can effectively press the nut downwards, improving the stable clamping force.

[0051] Example 2

[0052] As another embodiment of the present invention, a stepped transmission frame is provided. The stepped transmission frame includes two sets of eccentric cam transmission assemblies disposed on a base plate 111, and a second support frame 7116 in the middle of the two sets of eccentric cam transmission assemblies and a first support frame 7115 on both sides. A plurality of second vertical rods 71161 and first vertical rods 71151 are linearly distributed on the second support frame 7116 and the first support frame 7115, and each second vertical rod 71161 is located in the middle of two adjacent first vertical rods 71151. When the eccentric cam transmission assembly is running, it is used to raise and lower the first support frame 7115 on both sides and to raise and lower the second support frame 7116 in the middle.

[0053] Furthermore, each eccentric cam transmission assembly includes a first mounting base 7111, on which a rotatable positioning shaft 7120 and a drive shaft 7112 are respectively mounted front and rear. Transmission rods 7121 are rotatably mounted on both sides and the middle of the positioning shaft 7120. The two side transmission rods 7121 are rotatably connected to the corresponding first support frame 7115 via first pins, and the middle transmission rod 7121 is rotatably connected to the bottom end of the second support frame 7116 via a second pin. A second cam 7114 and a first cam 7113 for supporting the transmission rods 7121 are fixed to the middle and both sides of the drive shaft 7112. The first cam 7113 and the second cam 7114 are eccentrically opposite each other; it also includes a belt drive assembly for driving the two sets of eccentric cam drive assemblies. The belt drive assembly includes a first drive wheel 7130 and a second drive wheel 7131 connected to the ends of the drive shafts 7112 on the two sets of eccentric cam drive assemblies, a drive belt 7132 connected between the first drive wheel 7130 and the second drive wheel 7131, and a second mounting base 7133 fixed on the base plate 111. A second motor 7134 is fixed on the second mounting base 7133, and the output shaft of the second motor 7134 is connected to the shaft end of the first drive wheel 7130.

[0054] In this embodiment, a stepped transmission frame is further provided, which is mainly composed of an eccentric cam transmission assembly, such as... Figure 6 , 8 As shown in Figures 9 and 10, several transmission rods 7121 rotate around the positioning shaft 7120. Under the action of the belt transmission assembly, they can drive the drive shaft 7112 containing the two sets of eccentric cam transmission assemblies to rotate. Since the eccentric positions of the first cam 7113 and the second cam 7114 are opposite, when the drive shaft 7112 drives the first cam 7113 and the second cam 7114 on it to rotate, the first cam 7113 on both sides gradually eccentrically moves upward, driving the transmission rods 7121 on both sides to rise. At the same time, the second cam 7114 in the middle tends to eccentrically move downward, thus driving the transmission rod 7121 in the middle to fall. This achieves the effect that the first support frames 7115 on both sides rise while the second support frame 7116 in the middle falls, forming a concave V-shaped groove. When the first support frames 7115 on both sides fall, the second support frame 7116 in the middle rises, forming an upward convex inverted V-shaped slope. Figure 6 With the connection of several first vertical rods 71151 and second vertical rods 71161 arranged in succession, a continuous V-shaped clamping groove and an inverted V-shaped slope can be realized to allow the material to be rolled and fed step by step. At the same time, efficient peeling or shelling operations can be performed in the V-shaped clamping groove.

[0055] Example 3

[0056] In another embodiment of the present invention, the V-shaped connecting rod structure includes two first horizontal bars 812 and a second horizontal bar 817 located in the middle of the two first horizontal bars 812. The second horizontal bar 817 is connected to the top of each second vertical bar 71161. The two first horizontal bars 812 are rotatably mounted on the top of adjacent first vertical bars 71151 via mounting members 811 at both ends. A first elastic connecting member is fitted to the upper surface of the second horizontal bar 817. A transmission plate 820 is mounted on the top of the first elastic connecting member. Clamping plates 813 are respectively connected to the upper surfaces of the two first horizontal bars 812 via the second elastic connecting members. A connecting plate 816 is rotatably mounted between the two clamping plates 813 and the side wall near the transmission plate 820 via a connecting member 816. 27; Each clamping plate 813 has a first mounting strip 814 fixed at both ends, and a first shaft 815 rotatably mounted in the middle of the two first mounting strips 814. Each transmission plate 820 has a second mounting strip 821 fixed at both ends, and a second shaft 822 fixedly mounted in the middle of the two second mounting strips 821. The washing belt 826 passes through the first shaft 815 and the second shaft 822 in sequence along the material forward direction and extends to the ends of the first support frame 7115 and the second support frame 7116. There are also two sets of protective films 511 connected to the side walls of the first mounting strips 814 and the second mounting strips 821. The two sets of protective films 511 are made of elastic tensile material and are used to form a side protection structure for material feeding.

[0057] The further designed V-shaped linkage structure is a further design based on the stepped transmission frame in Embodiment 2, such as... Figure 10 , 11 As shown in Figure 12, the first support frame 7115 on both sides rises, causing the first horizontal bar 812 on both sides to rise. At the same time, the second vertical bar 71161 in the middle pulls the transmission plate 820 down. Under the transmission connection of the connecting plate 827, the clamping plates 813 on both sides can be driven to deflect towards the transmission plate 820, thus forming a concave V-shaped clamping groove. This clamps the material between the two limiting bars 825 and has a downward pressing effect, ensuring the stability of the material when the high-pressure water at the bottom is applied. When the first support frame 7115 on both sides descends, the second support frame 7116 in the middle rises. Under the transmission connection of the connecting plate 827, the clamping plates 813 on both sides deflect away from the transmission plate 820 and open, thus forming an upwardly convex inverted V-shaped slope.

[0058] Furthermore, the first elastic connector has the same structure as the second elastic connector. The first elastic connector includes a telescopic sleeve 818, a telescopic post 8181 that telescopically moves on the telescopic sleeve 818, and a spring 819 connected between the telescopic sleeve 818 and the telescopic post 8181.

[0059] By further configuring the first and second elastic connectors, a certain buffer can be provided for the concave V-shaped clamping groove. When the clamping force of the concave groove is too large, the elasticity of the first and second elastic connectors themselves can reduce the damage to the material caused by the excessive clamping force.

[0060] Example 4

[0061] In another embodiment of the present invention, the linear high-pressure water jet assembly includes a pipe body 824 mounted on a second shaft 822, and high-pressure nozzles 823 linearly distributed on the pipe body 824. Both ends of the pipe body 824 are connected to branch pipes 413. The frame 112 is fixed on a base plate 111. The front and rear ends of the frame 112 are respectively equipped with an installation pipe 412 and a water inlet pipe 414. The water inlet pipe 414 is used to connect to the high-pressure water device, and a connecting pipe 411 is connected between the water inlet pipe 414 and the installation pipe 412. The branch pipe 413 where each pipe body 824 is located is connected to the connecting pipe 411.

[0062] Through further configuration of the linear high-pressure water jet component, such as Figure 8 , 11 As shown, by connecting the inlet pipe 414 to the high-pressure water device, and connecting the connecting pipe 411 to several branch pipes 413, and then connecting the high-pressure nozzle 823 where the pipe body 824 is located, the high-pressure nozzle 823 can perform high-pressure spraying when the high-pressure water device is working.

[0065] In this embodiment, a shroud-type high-pressure water jet assembly is further provided, which can further compensate for the aforementioned linear high-pressure water jet assembly, such as... Figure 12 , 13 The linear high-pressure nozzle 3181 and the central spray plate 3183 are assembled on the upper and lower edges of the housing 318. The linear high-pressure nozzle 3181 uses a high-pressure nozzle, and the spray plate 3183 can use a general cleaning nozzle.

[0068] An automatic peeling method with high-pressure water jet is provided, applied to the aforementioned automatic peeling device with high-pressure water jet. The peeling method includes:

[0069] S1: Nuts enter the recessed V-shaped clamping groove. The nuts are placed at an angle under the support of the two limiting strips 825 and are positioned above the linear high-pressure water jet assembly. The cleaning belt 826 drives the limiting strips 825 on both sides to be recessed and clamp the material. The greater the recess of the V-shaped clamping groove, the greater the clamping force. In conjunction with the action of the linear high-pressure water jet assembly, the bottom linear high-pressure water jet assembly sprays several materials on the lower surface to perform a peeling action.

[0070] S2: When the V-shaped clamping groove reverses and switches to the upper convex inverted V slope, the forward-leaning nuts will roll down along the upper convex inverted V slope to achieve material feeding in stages. This cycle continues, and with the continuous tumbling of the nuts during the feeding process, the high-pressure impact effect of multiple tumbling is achieved in several V-shaped clamping grooves.
