Description

Technical Field

[0001] This application relates to the field of pitting equipment technology, and in particular to a pitting device for producing jujube paste. Background Technology

[0002] With the development of the food industry, people's demand for healthy snacks is constantly increasing. Jujube products (such as jujube paste) are widely popular due to their high nutritional value. However, in the early processing stage of jujube paste production, pitting is a crucial but inefficient process. Traditional manual pitting methods are not only time-consuming and labor-intensive but also easily damage the fruit pulp, affecting product quality and yield. Although automated equipment on the market has improved, it still has significant limitations in adapting to jujubes of different sizes and shapes. Furthermore, existing pitting technologies mostly rely on a single extrusion or cutting mechanism, which is difficult to meet the requirements of efficient continuous production. Overall, improving the efficiency of jujube pitting has become one of the bottlenecks restricting the development of the jujube paste industry.

[0003] Specific solutions from existing technologies: Currently common methods for removing pits from jujubes mainly include three types: manual tool operation, rotary blade cutting method, and hydraulic clamping fracturing method.

[0004] Among them, manual tool operation is the most primitive method, which involves manually removing the date pits one by one using specific small instruments. Its advantage is that it is highly flexible and can precisely control the force to avoid excessive damage to the fruit pulp; however, it also brings the problem of high labor intensity and is not suitable for large-scale industrial production environments. The rotary blade cutting method uses a high-speed rotating metal blade to quickly cut into the inside of the jujube to complete the separation action. This method requires cutting the fruit open to remove the pit, which causes damage to the fruit and poses certain safety hazards. Finally, we have the hydraulic clamping fracturing method. Based on the principles of physics, it uses a complex control system to apply uniform pressure to split the jujube along its natural structural lines and extract the seed. Theoretically, this method can better protect the integrity of the external tissue, but in practice, it is not widely adopted due to its high cost and complex maintenance.

[0005] Therefore, this application provides a jujube pitting device for producing jujube paste. Summary of the Invention

The surface of the fixing plate 301 is fixed with a first motor 308 for driving a conveying roller 302 to rotate.

[0033] Specifically, the rotation of the first motor 308 can drive the rotation of a conveyor roller 302, and the rotation of the conveyor roller 302 can drive the conveyor belt 303 to rotate automatically under the action of the other conveyor roller 302.

[0034] Please refer to this carefully. Figure 1 , Figure 3 The surfaces of the two fixed plates 301 are each fixed with a second mounting rod 202, and the ends of the two second mounting rods 202 are fixedly connected to the surface of the feeding funnel 201. The bottom of the feeding funnel 201 is a frame structure, and the bottom of the feeding funnel 201 corresponds to the placement block 304.

[0035] Specifically, the second mounting rod 202 can stably install the feeding funnel 201, and under the action of the limiting roller 203, the jujubes can be oriented to enter the interior of the placement groove 305 on the placement block 304. It should be noted here that the size of the placement groove 305 is important. After the placement groove 305 is set, it can only allow the jujubes to enter laterally.

[0036] Please refer to this carefully. Figure 1 , Figure 2 Two symmetrical third mounting rods 406 are fixedly mounted on the lower surface of the mounting plate 401. The bottom end of the third mounting rod 406 is fixedly connected to the upper surface of the base 100. The PLC controller 600 is fixedly mounted on the surface of the two third mounting rods 406.

[0037] Specifically, the third mounting rod 406 enables stable installation of the core removal mechanism 400, and at the same time, it enables automated control under the action of the PLC controller 600.

[0038] Please refer to this carefully. Figure 4 , Figure 5 Two symmetrical limiting rods 407 are fixedly provided on the surface of the mounting plate 401, and sliding frames 408 are slidably provided on the surface of the two limiting rods 407. Both ends of the sliding frames 408 are fixedly connected to the surface of the strip plate 402.

[0039] Specifically, under the action of the limit rod 407, the sliding frame 408 can move horizontally stably.

[0040] Please refer to this carefully. Figure 4 , Figure 5 The output end of the second motor 405 passes through the mounting plate 401 and is fixed with a reciprocating threaded post 409. The surface of the sliding frame 408 is provided with a threaded hole that is threadedly connected to the outer surface of the reciprocating threaded post 409. The surface of the sliding frame 408 is also provided with sliding holes that are slidably connected to the surfaces of the two limit rods 407 respectively.

[0041] Specifically, the reciprocating threaded column 409 can drive the sliding frame 408 to move horizontally automatically.

[0042] Please refer to this carefully. Figure 1 , Figure 4 The collection mechanism 500 includes a collection frame 501 disposed on the upper surface of the base 100, and an arc-shaped guide frame 502 is provided at the end of the collection frame 501. A core removal frame 503 is fixed on the upper surface of a fixing plate 301.

[0043] Specifically, the system can effectively collect the pitted jujubes through the arc-shaped guide frame 502 and the collection frame 501, and guide the jujube pits to fall through the pitting frame 503.

[0044] In this embodiment, by setting up a feeding mechanism 200, a conveying mechanism 300, a pitting mechanism 400, and a collecting mechanism 500, the device can place jujubes into the feeding funnel 201 when pitting them. Then, the first motor 308 is started to drive the conveyor roller 302 and the conveyor belt 303 to rotate. The rotation of the conveyor belt 303 causes several placement blocks 304 to move at a constant speed. During the movement of the placement blocks 304, the placement blocks 304 located at the bottom of the feeding funnel 201 can place the jujubes into the placement slot 305 in a specified direction under the action of the limiting roller 203. When the placement blocks 304 leave the feeding funnel 201 and move to the right side of the feeding funnel 201, the first motor 308 is turned off, and the second motor 405 is started. The rotation of the second motor 405 drives the reciprocating threaded column 409 to rotate, and the rotation of the reciprocating threaded column 409 drives... The sliding frame 408 moves horizontally under the action of the limiting rod 407. When the sliding frame 408 moves, it can drive the strip plate 402 to move. The movement of the strip plate 402 drives several pitting rods 403 to approach the placement block 304 at a uniform speed. Under the action of the annular blade 404, they are inserted into the jujube inside the placement groove 305, so that the pitting rods 403 can push the jujube pit forward and discharge it through the pitting hole 306 into the pitting frame 503. After the pitting rods 403 are reset, the first motor 308 is restarted to drive the conveyor belt 303 to continue moving, so that the pitted jujubes can automatically fall into the collection frame 501. Thus, the device can realize the automated pitting operation of a large number of jujubes, effectively improving work efficiency, without damaging the jujube flesh, and the whole device is low in cost, easy to maintain, and suitable for widespread use. Example

[0045] Based on Example 1, referring to Figures 6 to 8 And unlike Example 1, the following is true: Please refer to this carefully. Figure 6 , Figure 7 A positioning mechanism 700 is provided above the pitting mechanism 400, which is used to fix the red dates when pitting them in the placement groove 305. The positioning mechanism 700 includes a pressure plate 701 disposed above a plurality of placement blocks 304, and rubber blocks 702 disposed at equal intervals on the lower surface of the pressure plate 701 and corresponding to the placement grooves 305 on the placement blocks 304. The bottom end of the rubber blocks 702 is sloping.

[0046] Specifically, the pressure plate 701 and the rubber pressure block 702 can effectively limit and fix the jujubes in the placement groove 305.

[0047] Please refer to this carefully. Figure 7 , Figure 8 The positioning mechanism 700 also includes two symmetrical L-shaped connecting rods 703 fixed on the surface of the mounting plate 401. A connecting shaft 704 is rotatably provided on the opposite surface of the two L-shaped connecting rods 703. A pressure rod 705 is rotatably provided on the surface of the connecting shaft 704. A rotating hole is provided on the surface of the pressure rod 705 to rotatably connect with the surface of the connecting shaft 704.

[0048] Specifically, the pressure plate 701 and the rubber pressure block 702 can automatically press the jujubes by rotating the pressure rod 705 on the connecting shaft 704.

[0049] Please refer to this carefully. Figure 7 , Figure 8 Two symmetrical torsion springs 706 are sleeved on the surface of the connecting shaft 704, and one end of the torsion spring 706 is fixedly connected to the surface of the pressure rod 705, and the other end of the torsion spring 706 is fixedly connected to the surface of the L-shaped connecting rod 703. The positioning mechanism 700 also includes two symmetrical connecting rods 707 fixed on the upper surface of the sliding frame 408, and the ends of the two connecting rods 707 are fixedly provided with push blocks 708. The end surface of the pressure rod 705 is fixedly provided with a triangular block 709 that matches the push block 708, and the cross-sectional shape of the triangular block 709 is a right triangle. The lower surface of the push block 708 is a slope-shaped structure that matches the inclined surface of the triangular block 709.

[0050] Specifically, under the action of the torsion spring 706, the pressure plate 701 and the rubber pressure block 702 can automatically press and fix the jujubes. At the same time, during the resetting process of the sliding frame 408 and the pitting rod 403, the push block 708 can push the triangular block 709 downward and squeeze it, thereby driving the pressure rod 705 and the pressure plate 701 to reset.

[0051] In this embodiment, by setting a positioning mechanism 700, during the process of the second motor 405 rotating and driving the pitting rod 403 to insert into the jujube, the movement of the sliding frame 408 can drive the push block 708 to move through the two connecting rods 707. The movement of the push block 708 causes the push block 708 to disengage from the triangular block 709. At this time, the pressure rod 705 can rotate under the action of the torsion spring 706, causing the pressure plate 701 to automatically press down, thereby enabling the rubber pressure block 702 to automatically press and fix the jujube in the placement groove 305, effectively ensuring the stability of the jujube during pitting. Moreover, during the resetting process of the sliding frame 408 and the pitting rod 403, the push block 708 can push and squeeze the triangular block 709 downward, thereby driving the pressure rod 705 and the pressure plate 701 to reset, which facilitates continuous pitting of the jujube.

[0052] Working principle: When pitting jujubes, they are placed into the feeding hopper 201. Then, the first motor 308 is started, driving the conveyor roller 302 and the conveyor belt 303 to rotate. The rotation of the conveyor belt 303 causes several placement blocks 304 to move at a constant speed. During the movement of the placement blocks 304, the placement blocks 304 located at the bottom of the feeding hopper 201 can place the jujubes into the placement groove 305 in a specified direction under the action of the limiting roller 203. When the placement blocks 304 leave the feeding hopper 201 and move to the right side of the feeding hopper 201... Then, the first motor 308 is turned off, and the second motor 405 is started. The rotation of the second motor 405 drives the reciprocating threaded column 409 to rotate. The rotation of the reciprocating threaded column 409 drives the sliding frame 408 to move horizontally under the action of the limiting rod 407. When the sliding frame 408 moves, it can drive the strip plate 402 to move. The movement of the strip plate 402 drives several pitting rods 403 to approach the placement block 304 at a uniform speed, and under the action of the annular blade 404, they are inserted into the jujube inside the placement groove 305, so that the pitting rods 403 can remove the pitting rods. The pit of the jujube is pushed forward and discharged through the pitting hole 306 into the pitting frame 503. After the pitting rod 403 resets, the first motor 308 is restarted to drive the conveyor belt 303 to continue moving, so that the pitted jujubes can automatically fall into the collection frame 501. Moreover, during the process of the second motor 405 rotating and driving the pitting rod 403 to insert into the jujube, the movement of the sliding frame 408 can drive the push block 708 to move through the two connecting rods 707. The movement of the push block 708 causes the push block 708 to disengage from the triangular... The triangular block 709 is formed, and the pressure rod 705 can rotate under the action of the torsion spring 706, so that the pressure plate 701 automatically presses down, thereby enabling the rubber pressure block 702 to automatically press and fix the jujubes in the placement groove 305, effectively ensuring the stability of the jujubes during pitting. Moreover, during the resetting process of the sliding frame 408 and the pitting rod 403, the push block 708 can push the triangular block 709 downward and squeeze it, thereby driving the pressure rod 705 and the pressure plate 701 to reset, which facilitates continuous pitting of jujubes.
