Description

Technical Field

[0001] The present invention relates to the technical field of agricultural product processing, and particularly relates to a pomelo peeling and pulp separating device and a using method thereof. Background Art

[0002] A pomelo peeling and pulp separating device is a mechanical equipment specifically used for automatically or semi-automatically removing the epidermis of pomelos and separating the pulp from the peel. This device realizes the fixation, rotation, and epidermal cutting of pomelos through mechanical structures (such as fixed needles, rotating platforms, peeling knives, etc.). At the same time, it uses cleaning modules (such as brushes or air nozzles) to remove the remaining epidermis to ensure the complete separation of the pulp. Its core functions are to improve the peeling efficiency, reduce manual operations, lower the pulp damage rate, and adapt to pomelos of different sizes and shapes. This device is widely used in fields such as food processing and deep processing of agricultural products, and is an important equipment for improving the automation level and product quality of pomelo processing.

[0003] The fixing module on the pomelo peeling machine is used to fix the pomelo to ensure its stability during the peeling process. The distance between the fixed needles in the fixing module is fixed and cannot be adjusted. When processing some larger pomelos, the centrifugal force generated during rotation is stronger, and the fixed spacing may not provide enough supporting force to offset this centrifugal force, resulting in the offset of the pomelo and affecting the peeling effect of the pomelo.

In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0038] Embodiment 1

[0039] Refer to Figures 1 - 5, which is the first embodiment of the present invention, provides a pomelo peeling and pulp separating device. This device includes,

[0040] A peeling mechanism 100, including a pomelo peeling machine 110, a rotating motor 120 fixedly installed in the inner cavity of the pomelo peeling machine 110, a threaded column 130 fixedly installed at the output end of the rotating motor 120, a support plate 140 fixedly installed at the end of the threaded column 130 for placing the pomelo, and a number of fixing needle components 150 arranged on the surface of the support plate 140 for fixing the pomelo;

[0041] And,

[0042] An adjusting mechanism 200, including an adjusting component 210 for adjusting the fixed spacing of a number of fixing needle components 150, and an auxiliary component 220 for assisting the fixing needle components 150 to further fix the pomelo;

[0043] The adjusting component 210 includes a threaded sleeve 211 threadedly sleeved on the surface of the threaded column 130, a mounting sleeve 212 rotatably installed on the surface of the threaded sleeve 211, and a number of transmission rods 213 hinged on the surface of the mounting sleeve 212. The other end of the transmission rod 213 is hinged to the bottom of the fixing needle component 150.

[0044] Among them, by rotating the threaded sleeve 211, with the cooperation of the threaded column 130, the threaded sleeve 211 moves up and down on its surface. Then, the threaded sleeve 211 drives the mounting sleeve 212 to move up and down, and the mounting sleeve 212 drives the transmission rod 213 to rotate. The transmission rod 213 plays a role of pushing and pulling on the fixing needle component 150, thereby adjusting the fixed distance between a number of fixing needle components 150, providing a good support and limiting effect for pomelos of different sizes, and thus improving the stability of the pomelo during peeling.

[0045] Specifically, the adjusting component 210 further includes a number of sliding grooves 214 opened on the surface of the support plate 140 and used for cooperating with the movement of the fixing needle component 150. The sliding grooves 214 play a role of limiting the fixing needle component 150.

[0046] Among them, the sliding grooves 214 are used for moving and limiting the fixing needle component 150, playing a guiding role for the fixing needle component 150 to prevent it from shifting.

[0047] Furthermore, a guiding groove is opened in the inner cavity of the sliding groove 214, and a guiding block for cooperating with the guiding groove to limit the fixing needle component 150 is fixedly installed on the surface of the fixing needle component 150.

[0048] Among them, through the cooperation between the guiding groove and the guiding block, it is used for moving and limiting the fixing needle component 150, keeping the fixing needle component 150 in a vertical state, and facilitating the fixing needle component 150 to insert into the interior of the pomelo.

[0049] Preferably, an annular limiting strip 215 is fixedly installed on the surface of the threaded sleeve 211, and an annular groove for cooperating with the annular limiting strip 215 is formed on the inner side of the installation sleeve 212.

[0050] Wherein, through the cooperation between the annular limiting strip 215 and the annular groove, the threaded sleeve 211 and the installation sleeve 212 are rotationally connected, so that the threaded sleeve 211 can drive the installation sleeve 212 to move up and down when rotating.

[0051] During use, according to the size of the actual processed pomelo, the fixing distance of the fixing needle component 150 is adjusted. The threaded sleeve 211 is rotated, and the threaded sleeve 211 drives the installation sleeve 212 to move up and down. The installation sleeve 212 drives the transmission rod 213 to push and pull a plurality of fixing needle components 150, thereby adjusting the fixing distance of the fixing needle components 150.

[0052] In summary, the adjusting component 210 is used to adjust the fixing distance between a plurality of fixing needle components 150, solving the problem that the fixing distance of the traditional fixing needle component 150 cannot be adjusted. When processing some larger pomelos, the centrifugal force generated during rotation is stronger, and the fixed distance may not provide enough supporting force to offset this centrifugal force, resulting in the pomelo shifting and affecting the peeling effect of the pomelo.

[0053] Embodiment 2

[0055] Wherein, when the pomelo is placed on the annular plate 223, the bottom of the pomelo presses down on the convex column 222. Then, the bottom of the convex column 222 presses on a plurality of transmission plates 225, causing them to rotate. The end of the transmission plate 225 will push the annular plate 223 upward. Then, the annular plate 223 drives the pins 224 to penetrate the reserved slots on the support plate 140 and insert into the pomelo interior to further fix the pomelo.

[0056] Furthermore, the auxiliary component 220 further includes a reset spring 226 fixedly installed in the inner cavity of the cylindrical groove 221. A groove is formed at the bottom of the convex column 222, and the end of the reset spring 226 extends into the groove and is fixedly connected to the convex column 222.

[0057] Among them, the reset spring 226 is used to reset the convex column 222 upward elastically, which is convenient for the next use and avoids affecting the fixing effect of the pomelo next time.

[0058] Furthermore, a number of empty slots for the rotation of the transmission plate 225 are provided on the surface of the threaded column 130, and the transmission plate 225 is rotationally connected through a rotating rod fixedly installed inside the empty slot.

[0059] Among them, through the cooperation between the empty slot and the rotating rod, it is used to rotate the transmission plate 225 and provide a space for the transmission plate 225 to rotate.

[0060] When in use, when the pomelo is placed on the support plate 140, the convex column 222 is pressed downward by the pomelo, and the bottom of the convex column 222 presses a number of transmission plates 225 to make them rotate. Furthermore, the other end of the transmission plate 225 will exert an upward and downward thrust on the annular plate 223, and the upward movement of the annular plate 223 drives a number of pins 224 to insert into the inner part of the pomelo skin, completing the fixation of the pomelo.

[0061] In summary, the auxiliary component 220 is used to further fix the pomelo, improve the stability of the pomelo during rotation, and further improve the peeling effect of the pomelo.

[0064] Among them, a first thread groove for the use of the first screw rod 154 is provided at the top of the needle body 151, and a second thread groove for the use of the second screw rod 155 is provided at the top of the connecting portion 152. Through the cooperation between the first screw rod 154 and the first thread groove, it is used to disassemble the connecting portion 152, which is convenient for controlling the number of the connecting portion 152 and the needle tip 153, and can be increased or decreased according to the size of the pomelo to provide a good support point; through the cooperation between the second screw rod 155 and the second thread groove, the use length of the needle tip 153 is adjusted to increase the insertion depth into the pomelo and improve the fixing effect.

[0065] In use, the number and length of the fixing needle components 150 are adjusted according to the size of the pomelo. The connecting part 152 can be disassembled conveniently through the first screw 154 and the first thread groove to control the number of the connecting part 152 and the needle tip 153 used. Through the action of the second screw 155 and the second thread groove, the using length of the needle tip 153 can be adjusted.

[0066] In order to demonstrate the performance of the present invention and traditional equipment in terms of the peeling efficiency and pulp damage rate of pomelos, experiments were carried out.
