Description

Technical Field

[0001] This utility model belongs to the technical field of water chestnut peeling equipment, specifically a water chestnut supporting and fixing punching mechanism. Background Technology

[0002] Traditional methods of shelling and extracting kernels from water chestnuts typically involve using scissor-like shelling tools or shearing mechanisms, or manually cutting multiple surfaces with a knife to remove the kernels. However, because the water chestnut shell is quite rough, hard, slippery, and has an extremely irregular surface, it is not easy to grasp it by hand and then use tools to break it open. All these manual shelling and kernel extraction methods are invariably inefficient, limiting the development of the water chestnut industry.

[0003] Therefore, the applicant proposes a brand-new water chestnut peeling machine. Since the shape of water chestnuts varies greatly and they are very difficult to fix, how to fix the water chestnuts is a key technology in order to better complete the peeling process. Therefore, a water chestnut fixing structure is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a diamond-shaped support and fixing mechanism for a punch shell, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A diamond-shaped support and fixing mechanism for a punch shell includes:

[0007] The frame has at least one positioning station, which provides a bottom and front support point for the rhombus. For each positioning station, a movable fixing component is installed above it.

[0008] The positioning station is provided with two adjacent support members. Each of the two support members has a front support part and a bottom support part. The bottom support part corresponds to the bottom of the rhombus and a limiting flange is provided on the bottom support part. The limiting flange corresponds vertically to the front support part and together forms the front support of the rhombus. The front support part and the limiting flange support have a notch through which the saw blade passes.

[0009] In a further technical solution, the support member is sheet-shaped, with the front support portion corresponding to both sides of the fruit beak.

[0010] A further technical solution is that a conveying device is installed on the frame, and there are multiple positioning stations, all of which are installed on the conveying device, with a baffle plate provided on one side of the positioning station.

[0011] In a further technical solution, the fixing component applies a downwardly inclined pressure to at least the upper surface region of the rhombus.

[0016] A further technical solution includes a support device located at the shelling device. The support device includes a fifth cylinder, and a support plate is installed at the output end of the fifth cylinder. The support plate is provided with a first clearance position, a second clearance position, and a third clearance position. The first clearance position corresponds to the support member and is used to support the bottom surface of the rhombus on the support plate.

Detailed Implementation

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0039] Please refer to Figure 1-13 ;

[0040] The water chestnut peeling machine referred to in this utility model shall include a frame, on which a cutting device 4 and a peeling device 5 are installed. At least one positioning station 2 is provided on the frame. Assuming that the equipment has only one positioning station 2, the cutting device 4 and the peeling device 5 are both set near this positioning station 2. During operation, water chestnuts are placed into this positioning station 2 by manual feeding, and then fixed, cut and peeled. After that, they are taken out manually. Alternatively, multiple positioning stations 2 are arranged in a straight line on the frame. Each positioning station 2 is equipped with a fixing component 3 and a peeling device 5. The cutting device 4 moves in a straight line to cut the water chestnuts in several positioning stations 2 from the side, and then the peeling device 5 corresponding to each positioning station 2 peels the water chestnuts.

[0041] In another embodiment, it is assumed that a conveyor device 1 is provided on the frame. The conveyor device 1 can be a straight line or a turntable, etc. The conveyor device 1 is provided with several positioning stations 2. The cutting device 4, the shelling device 5, and the reset assembly 6 are arranged along the running direction of the conveyor device 1. The shelling step in this embodiment mainly consists of feeding, cutting, shelling, and unloading. Therefore, four positioning stations 2 can be set. Of course, the possibility of setting waiting stations is not excluded. Assuming that four positioning stations 2 are set, each positioning station 2 is distributed at 90°. Preferably, a baffle 26 is provided on one side of the positioning station 2 located in an adjacent position to prevent splashing to other areas during the cutting process.

[0042] It should be noted that since the complete production process includes a cutting step, which is close to the feeding position, a baffle plate 26 is set up to separate the feeding position from the cutting position, so as to avoid personal injury accidents caused by the saw blade cutting the operator during cutting, and to prevent fruit chips from flying into other areas during the process.

[0043] In this embodiment, the positioning station 2 provides at least the bottom and front support points for the rhombus. For each positioning station 2, a movable fixing component 3 is installed above it. When the rhombus is placed on the positioning station 2, pressure is applied to the upper surface of the rhombus in conjunction with the fixing component 3 to achieve clamping and fixing.

[0044] To simplify the explanation of the definition of the orientation of a water chestnut, refer to... Figure 5 and Figure 6 This includes the upper surface region a, the front side region b, the lower surface region c, the two sharp corners d, and the two rear side regions e. Even though the shapes of the rhombuses vary, the upper surface region a and the lower surface region c of the rhombuses have irregular convex and concave parts, and the sides have irregular convex parts. Even so, the applicant found that the rhombuses have at least a few common points: the convex parts are distributed in the upper surface region a, the concave parts are distributed in the lower surface region c, the front side region b has a protruding beak f, the two sides of the beak form a depression g, and there is a kernel part in the middle. The sharp corner d is basically kernelless. It should be noted that the model in the figure is only for illustration and does not represent the actual shape of the rhombus. Based on the above characteristics, a set of structures that can fix the rhombuses was designed. Whether the rhombuses are fixed firmly will directly affect the subsequent processing steps. The structure of the positioning station 2 will be described in detail below.

[0045] In this embodiment, refer to Figures 5-7At the positioning station 2, there are two adjacent support members 21. The two support members 21 are arranged opposite each other. Each support member 21 has a front support part 22 and a bottom support part 23. A limiting flange 24 is provided on the bottom support part 23. The limiting flange 24 corresponds vertically to the front support part 22. When loading, the fixing component 3 is in a state away from the positioning station 2. At this time, there is enough space to place the rhombus on the two support members 21. At this time, the two bottom support parts 23 correspond to the bottom of the rhombus. The rhombus is pushed forward so that the front support part 22 and the limiting flange 24 both abut against the recessed position g, forming a front support for the rhombus. The space between the other two support members 21 is a clearance position for the fruit beak f. The front support part 22 and the limiting flange 24 support the notch 25 through which the saw blade passes. Then the fixing component 3 is released so that it applies pressure to the upper surface of the rhombus to achieve fixation.

[0046] Although the lower surface area c of the rhombus is relatively flat, there are still uneven areas. If the bottom support 23 uses a support plate as support, it is difficult to lay the rhombus flat, and it may lift up. During the cutting process, the saw blade generates a huge centrifugal force, which may cause the position of the rhombus to deviate, thus affecting the subsequent shelling step. Therefore, this embodiment uses two independent bottom support 23 to form two support points on the bottom surface of the rhombus, reducing the contact area of ​​the lower surface area c, eliminating lifting and sliding caused by unevenness, and improving the fixing effect.

[0047] In addition, during the cutting process, the lower surface area c of the rhombus needs to be removed. After the cutting is completed, the lower surface area c separates from the main body of the rhombus. Under the centrifugal force of the saw blade, it may fly out of the positioning station 2, which will cause the rhombus to become thinner. Since there is a small gap between the saw blade and the bottom support 23, the distance between the front support 22 and the bottom support 23 is greater than the gap. During the cutting process, the rhombus may be pushed into the gap between the bottom support 23 and the front support 22, causing the rhombus to deviate. Therefore, this embodiment reduces the gap by setting a limiting flange 24, which can strengthen the support of the front side of the part and prevent the rhombus from being pushed forward. At the same time, the notch 25 formed can still allow the saw blade to pass through.

[0048] Preferably, the support member 21 in this embodiment is sheet-shaped, which further reduces the support area for the rhombus, but can still provide support. Moreover, due to the reduction in the support area, the fixing effect is strengthened. Preferably, the support members 21 on both sides can be integrated, and the shape can be sheet-shaped or thin block-shaped.

[0049] In this embodiment of the invention, the fixing component 3 applies a downward pressure to the upper surface area of ​​the water chestnut. During operation, the water chestnut is first fed based on the above-described method. The lower surface area c of the water chestnut is placed face down in the positioning station 2, so that the lower surface area c and the front side area b of the water chestnut are in contact with the positioning station 2 respectively. Then, the fixing component 3 is released to apply an inclined external force to the upper surface area a of the water chestnut. The inclined external force is dispersed into a downward force and a forward force, thereby fixing the water chestnut on the positioning station 2. Then, the conveying device 1 drives the positioning station 2 to the position corresponding to the cutting device 4. The cutting device 4 cuts the lower surface area to separate it from the main body. Of course, during the cutting process, a small part of the kernel near the lower surface area will be cut off, but it will not affect the integrity of the kernel.

[0050] After the cutting is completed, the cutting device 4 exits. Due to the external force applied by the fixing component 3, the lower surface area remains in its original position, only separated from the main body of the water chestnut. Then, the conveying device 1 drives the positioning station 2 to rotate and reach the shelling device 5. The shelling device 5 pushes several shelling claws to extend from bottom to top at the same time, causing the outer skin of the side of the water chestnut to turn upward and separate from the kernel. At this time, only a small part of the upper surface area a is stuck to the kernel. It can be gently peeled off manually. Therefore, in this equipment, it is not necessary to separate the complete outer skin from the kernel. Finally, the conveying device 11 drives the positioning station 2 to move to the next position, and the fixing component 3 resets to contact the fixing of the water chestnut and finally unloads the material.

[0051] This invention employs a specific cutting position and innovatively uses side shelling and a special clamping method to separate most of the outer shell covering the kernel, leaving only a small portion of the outer shell on the upper surface. This does not affect the integrity of the kernel, and prevents the kernels from stacking and sticking together during collection. Moreover, the kernels can be easily removed by gently breaking them apart without the need for additional tools.

[0052] One embodiment of the present invention relates to the fixing component 3, see below. Figure 3 and Figure 4Specifically, it includes a fixed plate 311, which is located above the positioning station 2 and is fixedly installed on the conveying device 1. A first movable member 312 is provided through the fixed plate 311 and a locking handle 313 is rotatably connected to it. In this embodiment, the first movable member 312 may be composed of several movable rods 3121 and triggers 3122. The first movable member 312 is inclined towards the positioning station 2, and a first mounting part 314 is provided at one end near the positioning station 2. The locking handle 313 can limit the position of the first mounting part 314. A first spring-loaded member 315 is provided on the bottom surface of the first mounting part 314 and the fixed plate 311. A first limiting groove 316 is provided on the first mounting part 314. A first clamping plate 317 is placed in the first limiting groove 316 and rotatably connected to the first mounting part 314. The width of the first limiting groove 316 is slightly larger than the width of the first clamping plate 317, so that it can swing slightly in the first limiting groove 316.

[0053] In the initial state, the locking handle 313 fixes the first mounting part 314, and the first spring-loaded member 315 is compressed, putting the whole in a tightened state. After the rhombus is placed in the positioning station 2, the locking handle 313 is rotated to release the lock on the first mounting part 314. Then, under the push of the first spring-loaded member 315, the first movable member 312, the first mounting part 314, and the first clamping plate 317 are tilted towards the upper surface area a of the rhombus. Finally, the end of the first clamping plate 317 abuts against the upper surface area a of the rhombus. The aforementioned upper surface area a of the rhombus has irregular protrusions and concave parts, therefore, in the first The outer end of the clamping plate 317 is provided with a "V" shaped groove 318 to form two fixing points. When one of the fixing points first contacts the protrusion, the first clamping plate 317 will shift due to its movable characteristic, so that the other fixing point enters the recess, ensuring that there are two fixing points. Based on the above structure, it can be ensured that the rhombus is firmly fixed in the positioning station 2 without shifting. It should be noted that since the offset angle of the first clamping plate 317 is not very large, there is no need to set a separate reset structure. Of course, it is also possible to set a torsion spring, tension spring or other reset components at the rotating connection, which will not affect the use.

[0054] One embodiment of the present invention relates to the shell-removing device 5, see reference to Figure 8 , Figure 10 and Figure 11Specifically, it includes a first cylinder 51 arranged longitudinally. The first cylinder 51 is installed below the conveying device 1 and will not move with it. A fixed seat 52 is installed at the output end of the first cylinder 51. The fixed seat 52 is provided with at least one fixed claw 53 and several movable claws 54 distributed on the left and right. Preferably, there are four movable claws 54. The movable claws 54 and the fixed seat 52 are rotatably connected and reset. For example, a torsion spring or other components are provided at the rotatable connection to realize the reset operation. One fixed claw 53 corresponds to the position of the fruit beak f. A pair of movable claws 54 are located in the two rear side areas e behind the sharp corner d. Another pair of movable claws 54 are located in the front side area b near the depression g in front of the two sharp corners d. A first inclined surface is provided at the end of the movable claw 54. A claw hook 55 is provided at the lower end of the first inclined surface.

[0055] It should be noted that the more movable claws 54 are set in a limited space, the better, so that they can cover a larger area of ​​the rhombus side and reduce the empty space. The number of fixed claws 53 can be two, set at the front and back respectively.

[0056] In the initial state, apart from the fixed claw 53, the space enclosed by the four movable claws 54 is smaller than the base area of ​​the rhombus. When the first cylinder 51 pushes the whole structure upward, the first inclined surface at the end of the movable claw 54 will first contact the lower surface area b and slide along the inclined surface to gradually open, so that the claw hook 55 reaches the cutting opening of the lower surface area b. At the same time, it will be inserted into the inner side of the rhombus from the opening. The first cylinder 51 continues to rise, and under the combined action of the fixed column and several movable claws 54, the side of the rhombus and the sharp corner d are lifted up together, leaving only a small part of the upper surface area a to stick to the kernel. It should be noted that the outer shell of the rhombus is relatively hard. Although there are only five support points, other parts will be lifted up together during the process of lifting the outer shell, so the entire side can be lifted up together. In addition, the inner side of the fixed claw 53 is provided with a second clearance groove 56, mainly to avoid cutting the kernel.

[0057] However, there is a problem. After the bottom of the water chestnut slides out of the root of the first inclined surface, it will directly reach the position of the claw hook 55. At this time, the moving claw 54 continues to move upward and the claw hook 55 will move in an arc trajectory. The corner is relatively large and may touch the bottom of the kernel and scratch it. Moreover, the claw hook 55 is inclined along the first inclined surface, which may result in the inability to remove the shell. Therefore, in this embodiment, a vertical surface is also provided between the first inclined surface and the claw hook 55.

[0058] based on Figure 11It can be seen that several limiting grooves are provided on both sides of the fixed base 52, and the movable claw 54 is placed in the limiting groove and close to the inner wall of the limiting groove. Therefore, the rotation range of the movable claw 54 is limited. The first inclined surface at the end of the movable claw 54 will first contact the lower surface area b and slide along the inclined surface to gradually open. After sliding out of the root of the first inclined surface, it enters the vertical surface position. At this time, the root of the movable claw 54 abuts against the fixed base 52 and can no longer rotate. The vertical surfaces of several movable claws 54 cooperate to form a clamping state on the side of the rhombus and simultaneously position the rhombus. The movable claw 54 continues to move upward, and the vertical surface plays a guiding role, so that the movable claw 54 moves vertically. That is, the claw hook 55 will only move vertically, ensuring that the shell can be removed and avoiding damage to the kernel. In addition, since the thickness of the rhombus shell is different in different seasons and environments, the lateral distance of the claw hook 55 is set to 1mm-3mm. Different claws are replaced according to different situations.

[0059] In another embodiment, the movable claw 54 is slightly tilted in the initial state, and the vertical plane is also tilted. When working, the movable claw 54 is squeezed and rotated at a certain angle, and the entire movable claw 54 becomes vertical or nearly vertical, and the vertical plane becomes vertical or nearly vertical, so that the claw hook 55 can move vertically.

[0060] In addition, the upper end of the fixed claw 53 is higher than the position of the claw hook 55. Since the fruit beak is the thickest part, more force is needed to remove it. Therefore, during operation, all the force is first concentrated on the fixed claw 53. The fixed claw 53 will press against the fruit beak to make it open. Then, the movable claw 54 will be used to remove the shell from the remaining sides.

[0061] Based on the fact that the shelling action is an upward punching motion, in order to strengthen the fixing of the diamond corners, the fixing component 3 also includes a longitudinally arranged fixing structure, specifically including a longitudinally arranged second movable part 321. The second movable part 321 passes through the conveying device 1. It should be noted that the second movable part 321 can be directly movably connected to the conveying device 1, or it can be installed on the fixed plate 311 and then rotated through it. A second mounting part 322 is provided at one end near the positioning station 2. A second limiting groove 323 is provided on the second mounting part 322. A second clamping plate 324 is placed in the second limiting groove 323 and rotatably connected to the second mounting part 322. A top pressing part 327 is provided at the other end of the second movable part 321. A second spring pressing part 328 is provided between the top pressing part 327 and the conveying device 1. Of course, the spring pressing part can also be provided between the fixed plates 311. A second cylinder 329 is provided above the top pressing part 327. The second cylinder 329 is installed on the frame.

[0062] In the initial state, the second spring-loaded member 328 applies external force to the top-pressing part 327 to lift the second movable member 321, so that the second clamping plate 324 is away from the upper surface area a of the rhombus. During operation, the second cylinder 329 applies a downward force to the top-pressing part 327, compressing the second spring-loaded member 328 and causing the second movable bracket to move downward, the second mounting part 322 and the second clamp to move downward. Finally, the end of the second clamping plate 324 abuts against the upper surface area a of the rhombus. The upper surface area a of the rhombus mentioned above has irregular protrusions and recesses. Therefore, a groove 325 is provided at the outer end of the second clamping plate 324, and several fixing protrusions 326 are provided along the inner side of the groove 325. At the same time, the second clamping plate 324 can be slightly rotated to ensure that a uniform downward force is applied to the rhombus to fix it.

[0063] It should be noted that the shelling device 5 operates by punching upwards from bottom to top, while the fixing structure is mainly provided with external force by the second cylinder 329. The force of the second cylinder 329 is fixed. Due to the special rhomboid structure, it is difficult to select a suitable cylinder, which leads to two problems.

[0064] First, if the force applied by the longitudinally fixed structure is insufficient, the shell-removing device 5 may lift the corners and the fixed structure during the process of moving from bottom to top to remove the shell, resulting in shell removal failure.

[0065] Second, if the force applied by the longitudinally fixed structure is large, the kernel may be broken because the positioning station 2 is composed of two thin support pieces 21 and there is no support in the middle position. This will not guarantee the integrity of the kernel and may also lead to shelling failure.

[0066] Based on the above problems, this embodiment also provides a supporting device 7 at the shelling device 5, referring to... Figure 8 and Figure 9 The supporting device 7 includes a fifth cylinder 71. A support plate 72 is installed at the output end of the fifth cylinder 71. The support plate 72 is provided with a first clearance position 73, a second clearance position 74 and a third clearance position 75. The first clearance position 73 corresponds to the support member 21, and the second clearance position 74 and the third clearance position 75 correspond to the shelling claw.

[0067] In the initial state, the supporting device 7 is located below the positioning station 2. After the rhombus is cut and reaches above the shelling device 5, the supporting device 7 moves before the longitudinal fixing structure and the shelling device 5. The fifth cylinder 71 causes the pallet 72 to rise, and the bottom support part 23 of the two support members 21 enters the first clearance position 73. The rest of the pallet 72 fills the outer periphery of the support member 21, so that the pallet 72 as a whole supports the bottom surface of the rhombus and expands the force-bearing area of ​​the bottom surface of the rhombus. Then, the longitudinal fixing structure moves downward to apply longitudinal pressure to the upper surface of the rhombus. The shelling device 5 pushes the movable claw 54 to rise, passing through the second clearance position 74 and the third clearance position 75 to act on the rhombus to complete the shelling.

[0068] After the shelling step is completed, the second cylinder 329 resets. Under the action of the second spring pressing component 328, the second movable component 321 drives the second clamping plate 324 to reset, removing the longitudinal force on the rhombus, but the lateral force still exists at this time.

[0069] Before unloading, the fixed component 3 needs to be reset, refer to... Figure 12 It also includes a reset component 6, which is used to pull the first movable member 312 to compress the first spring member 315; a lock hook 3131 is provided at one end of the lock handle 313 near the first mounting part 314, the lock hook 3131 has an inclined surface, a connecting plate 3141 is fixed on the first mounting part 314, the connecting plate 3141 abuts against the lock hook 3131; a handle 3132 is provided on the side of the lock handle 313 away from the lock hook 3131;

[0070] When the lock handle 313 is rotated, the lock hook 3131 will disengage from the connecting plate 3141. At this time, under the action of the first spring pressing member 315, the whole assembly is pushed out. After the lock handle 313 is released, it can automatically reset. That is, a torsion spring or other structure can be set at the rotating connection to realize the reset operation. When the whole assembly needs to be reset, the first movable assembly is pulled backward by the reset component 6. The connecting plate 3141 abuts against the inclined surface of the lock hook 3131, causing the lock handle 313 to flip. After crossing the inclined surface, the lock handle 313 resets and the lock hook 3131 fixes the connecting plate 3141 again.

[0071] Preferably, the reset assembly 6 includes a third cylinder 61 mounted obliquely on the frame, and a pull plate 62 is provided at the output end of the third cylinder 61. In the initial state, the third cylinder 61 is in the extended state and will not affect the movement of the first movable part 312. When it reaches the corresponding position, the pull plate 62 is in front of the trigger 3122. Then the third cylinder 61 retracts to make the pull plate 62 retract and abut against the trigger 3122 to pull it backward in sync.

[0072] After the fixed component 3 is reset, the material needs to be unloaded. In this utility model, a material-pushing brush is provided on the side near the material-loading position, and a material-unloading plate is provided on the side of the material-pushing brush. When the conveying device 11 drives the rhombus to rotate toward the material-loading position, the rhombus abuts against the side of the material-pushing brush and bends it. However, after bearing a certain pressure, the brush resets and pushes the rhombus out of the positioning station 2 in the opposite direction and into the material-unloading plate. The rhombus slides along the material-unloading plate to complete the unloading. Of course, other unloading methods can also be used, which will not be listed here.

[0073] This utility model further describes the cutting device 4, see reference 4. Figure 13The system includes a mounting base 41, on which a cutting assembly 42 is slidably connected. The cutting assembly 42 is connected to the output end of a fourth cylinder 43. Preferably, the outer shell near the fruit beak f is thicker, meaning the kernel in this part is smaller. Therefore, in this embodiment, the cutting blade of the cutting assembly 42 has an inclined angle to ensure that the lower surface c is completely cut off.

[0074] The cutting assembly 42 includes a motor and a saw blade. A barb assembly 44 is located below the saw blade. The barb assembly 44 moves forward with the cutting assembly 42. When the cutting assembly 42 completes the cutting, the barb assembly 44 is located on the front side of the rhombus. When the cutting assembly 42 moves backward, the barb assembly 44 moves backward as well, pushing out the lower surface area c to separate it from the main body.

[0075] In another embodiment, the cutting device 4 includes a lateral moving component and a cutting component 42. In this embodiment, the cutting opening is set at the position corresponding to the fruit beak f on the front side, and multiple positioning stations 2 are arranged in a straight line. The lateral moving component drives the cutting component 42 to move laterally.
