Description

Technical Field

[0001] This application relates to the field of material production technology, and in particular to a core extraction structure. Background Technology

[0002] Materials refer to all kinds of raw materials required in the production, manufacturing, or service process. In the production of food materials, it is a common step to cut a whole fruit in half and remove the pit, such as betel nuts, dried apples, and dried apricots.

[0003] The fruit halves are fed to a turntable station via a feeding process. A mounting plate is installed on the turntable, and the fruit halves are placed on it. The turntable rotates, transferring the fruit halves to the pitting process. The pitting process removes the pit from the inner cavity of the fruit halves on the mounting plate. Finally, the turntable rotates again, transferring the pitted fruit halves to the unloading process. To facilitate pitting the inner cavity of the fruit halves, a separation device is usually placed diagonally below the pitting process. Related technologies use a pitting separator, where the high-speed rotation of the separator's blades causes the fruit halves to impact the inner wall of the separator, achieving separation of the fruit halves from the pit.

[0004] The above-mentioned method of removing the pit from the inner cavity of the fruit half by a pitting separator will cause the fruit half to be damaged due to impact stress due to frequent impacts on the inner wall of the pitting separator. This results in low pitting efficiency and affects the quality of the finished fruit half. Summary of the Invention

[0005] To address the problem that frequent impacts of the fruit half against the inner wall of the pitting machine, which leads to low pitting efficiency and affects the quality of the finished fruit half, this application provides a pitting structure with the following technical solution: It includes a mounting frame, a support frame slidably connected to the mounting frame, a sliding device for driving the support frame to move on the mounting frame, and a pitting device for clamping the fruit pit from the inner cavity of the fruit half on the support frame.

[0006] In one specific implementation, the sliding device includes a drive cylinder mounted on a mounting bracket, and the support bracket is mounted on the slide of the drive cylinder.

[0007] In one specific implementation, the mounting bracket is provided with a guide rail, a guide block is slidably connected to the guide rail, and the support frame is disposed on the guide block.

[0008] In one specific implementation, the core-removing device includes a parallel finger cylinder mounted on a support frame, with a material-removing block on each of the two slides of the parallel finger cylinder.

[0009] In one specific implementation, the material taking block includes a bent plate disposed on the parallel finger cylinder, and the end of the bent plate opposite to the parallel finger cylinder is provided with a spike.

[0010] In one specific implementation, the core-removing device is located below the turntable, the spikes are tilted upwards, and the angle between the spikes and one of the mounting plates is in the range of 80~100°.

[0011] In one specific implementation, the support frame is provided with a drive slide, and the kernel-retrieving device is located at the moving end of the drive slide.

[0012] In one specific implementation, the mounting bracket is provided with a crash shield, the parallel finger cylinder is located on the inner edge of the crash shield, and the material picking block passes through the crash shield.

[0013] In one specific implementation, the anti-collision shell is provided with a stripping plate, which is located between the two spikes.

[0014] In one specific implementation, the mounting frame is provided with a feeding tray, which corresponds to the clamping end of the core-removing device.

[0015] In summary, this application has the following beneficial technical effects: when it is necessary to remove the pit from the inner cavity of the fruit half, the pit removal device clamps the pit from the inner cavity of the fruit half, the sliding device is activated, and the support frame is slid to remove the pit from the inner cavity of the fruit half. The use of clamping physical pit removal replaces high-speed impact separation, reduces the possibility of repeated collisions between the fruit half and the metal inner wall, fundamentally eliminates the damage problem caused by impact stress, and improves the yield of fruit half products.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a kernel extraction structure.

[0024] Example 1 Reference Figure 1 and Figure 2 The pitting structure includes a mounting frame 1, a support frame 2 slidably connected to the mounting frame 1, a sliding device on the mounting frame 1 to drive the support frame 2 to move, and a pitting device on the support frame 2 to clamp the pit from the inner cavity of the fruit half. In this embodiment, the pitting structure can be applied to food materials such as yellow peaches and areca nuts. This embodiment uses an areca nut cut into two pieces with similar dimensions and minimal difference in the position of the pit within the inner cavity of the pieces, set on the processing station 16 of a turntable 14. Therefore, when it is necessary to remove the pit from the inner cavity of the fruit half, the pitting device clamps the pit from the inner cavity of the fruit half, activates the sliding device, and drives the support frame 2 to slide, removing the pit from the inner cavity of the fruit half. This clamping-type physical pitting replaces high-speed impact separation, reducing the possibility of repeated collisions between the fruit half and the metal inner wall, fundamentally eliminating the damage caused by impact stress, and improving the yield of the fruit half.

[0025] Traditional pitting and separating machines in related technologies use mechanical impact to remove the pits from areca nut pieces. If the impact force is insufficient or the angle is off, the pit may not completely detach from the inner cavity of the piece, resulting in incomplete pitting. Mechanical impact can also easily damage the areca nut pieces, leading to a low yield. The pitting device in this embodiment acts directly on the pit through mechanical clamping, rather than the entire half of the fruit. Combined with the linear movement of the sliding device, it achieves high-precision pit-meat separation, making it particularly suitable for processing high-value materials such as areca nuts. Furthermore, the integrated design incorporates the pitting action into the turntable 14 production line. The sliding movement of the support frame 2 is synchronized with the turntable 14 station 16, optimizing process efficiency.

[0026] Reference Figure 1 and Figure 2The sliding device includes a drive cylinder 3 mounted on the mounting frame 1, and a support frame 2 bolted to the slide of the drive cylinder 3. In this embodiment, the drive cylinder is a slide cylinder, and the support frame 2 is bolted to the movable slide of the slide cylinder. A guide rail 4, parallel to the drive cylinder 3, is bolted to the mounting frame 1. A guide block 5 is slidably connected to the guide rail 4, and the support frame 2 is mounted on the guide block 5. The guide rail 4 limits the movement direction of the guide block 5, improving the stability of the support frame 2 during the sliding process. In this embodiment, the mounting frame 1 has a through hole, through which the support frame 2 passes. The guide rail 4 and the drive cylinder 3 are located on the two end faces of the mounting frame 1, respectively. The mounting frame 1 is designed with its two end faces separately, and the guide rail 4 and the drive cylinder 3 are located on opposite sides, which reduces the overall thickness of the core-removing structure while making the structure more compact and balancing the overall load of the mounting frame 1.

[0027] Reference Figure 3 and Figure 4 The kernel-removing device includes a parallel finger cylinder 6 mounted on a support frame 2. In this embodiment, the parallel finger cylinder 6 can also be a parallel finger electric cylinder; no limitation is made here. A material-removing block 7 is bolted to the two slides of the parallel finger cylinder 6. The material-removing block 7 includes a bent plate 8 mounted on the parallel finger cylinder 6, with a spiked block 9 fixedly connected to the end of the bent plate 8 facing away from the parallel finger cylinder 6. Each of the two spiked blocks 9 has an inclined surface located on the end face of one spiked block 9 furthest from the other. The inclined surface guides the spiked block 9 to enter the gap between the inner cavities of the fruit halves at a preset angle to grasp the kernel. Therefore, activating the parallel finger cylinder 6 causes the material-removing blocks 7 on the two slides of the parallel finger cylinder 6 to move relative to each other, allowing the two spiked blocks 9 to grasp the kernel in the inner cavity of the areca nut slice, clamping the kernel between the two spiked blocks 9.

[0028] Reference Figure 1 and Figure 2 A drive slide 10 is mounted on the support frame 2, and the pit-removing device is located at the moving end of the drive slide 10. In this embodiment, the drive slide 10 is an electric slide, and the pit-removing device is located on the moving slide of the electric slide. In this embodiment, the movement direction of the moving end of the drive slide 10 is perpendicular to the length direction of the guide rail 4. Since the mounting frame 1 is tilted towards the turntable 14 station 16 in this embodiment, the angle at which the thorn 9 pierces the inner cavity of the fruit half can be finely adjusted by ±10° through the sliding of the moving end of the drive slide 10. This allows the thorn 6 to adjust the piercing angle according to the different positions of the pit in the inner cavity of the fruit half, making the pit-removing flexibility of the thorn 9 stronger and improving the applicability of the thorn 6 to pits in different positions.

[0029] Reference Figure 3 and Figure 4A crash shield 11 is bolted to the mounting bracket 1. The parallel finger cylinder 6 is located on the inner edge of the crash shield 11, and the material picking block 7 passes through the crash shield 11. The crash shield 11 protects the parallel finger cylinder 6 on the inner edge, reducing the possibility of accidental damage to the parallel finger cylinder 6.

[0030] Reference Figure 1 and Figure 2 The mounting frame 1 is bolted to a feeding tray 13, which is made of food-grade stainless steel. The feeding tray 13 corresponds to the clamping end of the pitting device. In this embodiment, the feeding tray 13 is located below the pitting device. Baffles are fixedly connected to both sides of the feeding tray 13. After the pitting device completes the clamping and pitting, the feeding tray 13 forms a directional dropping area, so that the separated fruit pits can fall naturally into the collection box below the feeding tray 13, which facilitates the collection of fruit pits.

[0031] Reference Figure 1 and Figure 5 The pitting device is located below the turntable 14, with the spiked block 9 tilted upwards. The angle between the spiked block 9 and the mounting plate 15 is between 80° and 100°. In this embodiment, the angle between the spiked block 9 and the mounting plate 15 is set to 90°, i.e., a vertical layout is adopted. This facilitates the spiked block 9 to accurately pick up the areca nut kernels cut into pieces on the mounting plate 15 at the pitting station 16, thereby improving the accuracy of pitting.

[0032] The implementation principle of this application embodiment is as follows: When it is necessary to remove the pits from the areca nut pieces located at the pitting station 16 on the turntable 14, the drive cylinder 3 is activated, driving the support frame 2 to move towards the areca nut pieces, inserting the two spikes 9 into the inner cavity of the areca nut pieces; the parallel finger cylinder 6 is activated, driving the material-removing blocks 7 on the two slides of the parallel finger cylinder 6 to move relative to each other, and the two spikes 9 limit the pits in the inner cavity of the areca nut pieces, clamping the pits between the two spikes 9; then the drive cylinder 3 is activated again, driving the support frame 2 to reset, and when the pits move to the top of the feeding tray 13, the parallel finger cylinder 6 is activated again, the two spikes 9 release the limit on the pits, and the pits fall into the feeding tray 13 for feeding. The pits are removed from the inner cavity of the fruit half, and the clamping physical pit removal replaces high-speed impact separation, reducing the possibility of repeated collisions between the fruit half and the metal inner wall, fundamentally eliminating the damage problem caused by impact stress, and improving the yield of the fruit half.

[0033] Example 2 The difference between Embodiment 2 and Embodiment 1 is that a stripping plate 12 is provided on the anti-collision shell 11, and the stripping plate 12 is located between the two spikes 9. When facing areca nut pieces of similar size, the difference in the position of the kernel is small, and the spikes 9 can be used to remove the kernel of the areca nut piece by piercing it. When the areca nut piece on the turntable 14 rotates to the kernel removal station 16, the drive cylinder 3 is activated, which drives the support frame 2 to move towards the areca nut piece, so that the two spikes 9 are simultaneously inserted into the kernel of the areca nut piece. At this time, the inclined surface forms a wedge structure when the spikes 9 contact the kernel, which converts the vertical downward pressure into a lateral force, making it easier for the spikes 9 to pierce into the kernel. According to the actual situation on site, the drive slide 10 can be activated to fine-tune the position of the material removal block 7 on the parallel finger cylinder 6, thereby fine-tuning the insertion angle of the spikes 9 according to the position of the kernel. Then, the drive cylinder 3 is driven again to reset the support frame 2. During the movement, the fruit pits on the two spikes 9 come into contact with the stripping plate 12. At this time, the fruit pits are located at the top of the feeding tray 13. The stripping plate 12 acts as a blocking and limiting device for the fruit pits, removing them from the spikes 9. The removed fruit pits fall into the feeding tray 13 for feeding.

[0034] In addition, in this embodiment, the angle between the thorn block 9 and the mounting plate 15 is set to 90°, that is, a vertical layout is adopted. The two thorn blocks 9 penetrate the fruit kernel vertically to form a symmetrical peeling force field, so that the fruit kernel and the areca fiber bonding surface are evenly separated, reducing the possibility of unilateral fiber tearing due to the angle deviation of the oblique thorn, and improving the yield of areca nuts.
