A pitting device for processing red dates

Abstract

This utility model provides a pitting device for jujube processing, relating to the field of jujube pitting technology, including a set of support legs. In this utility model, the coordinated design of the transmission mechanism and the limiting groove frame achieves automated positioning and transmission of jujubes. Combined with the precise cooperation of the ejector pin and the waste removal sleeve, the pitting efficiency and integrity are significantly improved. The transmission mechanism uses a motor-driven pulley system to stably transport jujubes via a conveyor belt. The limiting groove frame provides lateral limiting, ensuring that the jujubes pass through the pitting station with consistent posture. The ejector pin and the waste removal sleeve are coaxially arranged. When the electric telescopic rod pushes the ejector pin, it can accurately squeeze the pit into the waste removal sleeve, avoiding fruit pulp residue. The pitting success rate is extremely high. The fully automated process reduces manual intervention and improves efficiency. Compared with traditional stamping-type pitting, the coaxial design of the ejector pin and waste removal sleeve structure can more completely preserve the jujube pulp, allowing the pitted jujubes to be directly used for further processing.

Description

Technical Field

[0001] This utility model relates to the field of jujube pitting technology, and in particular to a pitting device for jujube processing. Background Technology

[0002] With the increasing demand for healthy foods, red dates, as a natural ingredient rich in vitamins and minerals, have seen their market consumption rise year by year. According to the "China Food Industry Development Report," the scale of the red date deep processing industry has exceeded 100 billion yuan. Pitting, as a key pre-processing step in red date processing, directly affects the production cycle and quality of subsequent products. Traditional manual pitting suffers from low efficiency, high cost, and hygiene risks, while the widespread adoption of mechanized pitting equipment has become a core requirement for driving industry upgrading. Against this backdrop, the development of efficient, stable, and adaptable red date pitting equipment is of great significance for enhancing industry competitiveness and reducing production costs. Shortcomings of existing technology: 1) Insufficient pitting efficiency and precision: Traditional jujube pitting equipment mostly adopts a stamping or rotary structure, relying on fixed molds to adapt to jujubes of specific sizes. When processing jujubes of different varieties or sizes, problems such as incomplete pitting and fruit pulp residue are prone to occur, resulting in a high rework rate; moreover, the equipment operates at a slow speed, making it difficult to meet the needs of large-scale production.

[0003] 2) High damage rate of jujubes: Some equipment uses rigid clamping or squeezing to fix jujubes, which can easily cause damage to the flesh and cracking of the skin during the pitting process. This is especially serious for high-quality jujube varieties with thin skin and soft flesh, resulting in a raw material loss rate of 15% to 20%, which affects the yield and market value of the finished product.

[0004] 3) Complex equipment maintenance: The existing equipment has a compact structure and highly integrated core components (such as de-nucleating needles and conveyor belts). Once wear or failure occurs, the disassembly and replacement process is cumbersome and the maintenance time is long, increasing the downtime cost for enterprises. At the same time, the lack of modular design results in poor equipment versatility and difficulty in adapting to diverse production needs. Utility Model Content

[0005] The purpose of this invention is to solve the problems of insufficient pitting efficiency and accuracy, high damage rate of jujubes, and complex equipment maintenance in the existing technology, and to propose a pitting device for jujube processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pitting device for jujube processing, comprising a set of support legs, a mounting plate fixedly connected to the top of the set of support legs, a first base fixedly connected to the top of the mounting plate, and a transmission mechanism provided on the top of the first base; the transmission mechanism includes a motor, a first pulley fixedly connected to the output end of the motor, a jujube conveyor belt sleeved on the outer wall of the first pulley, a set of second pulleys being drivenly connected to the inner wall of the jujube conveyor belt, a mounting shaft fixedly connected inside each second pulley, and a second base fixedly connected to both ends of the mounting shaft.

[0007] Preferably, a limiting groove frame is fixedly connected to the top of the mounting plate, the opposite side of the limiting groove frame limits the outer surface of the conveyor belt, a calibration inlet is fixedly connected to the top of the limiting groove frame, and a discharge port is fixedly connected to the tail end of the limiting groove frame.

[0008] Preferably, a third mounting base is fixedly connected to the top of the mounting plate, an electric telescopic rod is fixedly connected to the top of the third mounting base, and a pin is fixedly connected to the output end of the electric telescopic rod.

[0009] Preferably, a fourth base is fixedly connected to the top of the mounting plate, a waste discharge sleeve is fixedly connected through the opposite side of the fourth base, and a soft pressing rod is fixedly connected to the outer surface of the fourth base.

[0010] Preferably, the output end of the ejector pin is movably disposed inside the limiting groove frame and cooperates with the waste discharge sleeve.

[0011] Preferably, the output end of the soft pressing rod cooperates with the outer wall of the conveyor belt.

[0012] Preferably, the jujubes enter through the calibration inlet, are pressed by the soft pressing rod, have their pits removed by the ejector pin, and are discharged through the discharge outlet.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the coordinated design of the transmission mechanism and the limiting groove frame realizes the automated positioning and transmission of jujubes. Combined with the precise cooperation of the ejector pin and the waste removal sleeve, the pitting efficiency and integrity are significantly improved. The transmission mechanism uses a motor-driven pulley system to stably transport jujubes via the jujube conveyor belt. The limiting groove frame provides lateral limiting to ensure that the jujubes pass through the pitting station with consistent posture. The ejector pin and the waste removal sleeve are coaxially set. When the electric telescopic rod pushes the ejector pin, it can accurately squeeze the jujube pit into the waste removal sleeve, avoiding fruit pulp residue. The pitting success rate is extremely high. The fully automated process reduces manual intervention and improves efficiency. Compared with the traditional stamping pitting method, the coaxial design of the ejector pin and waste removal sleeve structure can more completely preserve the jujube pulp, allowing the pitted jujubes to be directly used for further processing.

[0014] 2. The innovative application of the soft pressing rod and modular structure in this utility model not only protects the integrity of the jujube flesh but also improves the ease of maintenance and versatility of the equipment. The soft pressing rod is made of elastic material, providing sufficient fixing force when pressing the jujubes while avoiding skin damage caused by traditional rigid pressing plates, thus significantly reducing the jujube breakage rate. Each component is independently mounted on the mounting plate via a base, facilitating quick disassembly and replacement of vulnerable parts (such as the ejector pin or conveyor belt), shortening equipment maintenance time.

[0022] The overall effect of embodiment 2 is that the transmission system structure transmission mechanism 3 mainly consists of a motor 301, a first pulley 302, a date body conveyor belt 303, a second pulley 304, a mounting shaft 305, and a second base 306. The motor 301 serves as the power source, driving the first pulley 302 to rotate. The first pulley 302 causes the date body conveyor belt 303 to rotate through friction. The date body conveyor belt 303 then drives the second pulley 304 to rotate. The mounting shaft 305 serves to support and fix the second pulley 304. The second base 306 fixes the entire transmission mechanism 3 to the mounting plate 2. The date positioning and guiding system limiting groove frame 4 is installed on the mounting plate 2. Its opposite side is in close contact with the outer surface of the date body conveyor belt 303, which can effectively limit the position of the date during the transmission process and prevent it from deviating. The calibration inlet 41 is located at the top of the limiting groove frame 4 and is used to guide the date to accurately enter the limiting groove frame 4, ensuring the stability of the date during the transmission process.

[0023] Example 3: Please refer to the attached document. Figure 1 -Appendix Figure 4 As shown, the output end of the ejector pin 52 is movably set inside the limiting groove frame 4 and cooperates with the waste discharge sleeve 61.

The waste discharge sleeve 61 and the soft pressing rod 62 are installed on the fourth base 6. The waste discharge sleeve 61 is used to discharge the date pits, and the soft pressing rod 62 is used to press the dates during the pitting process to prevent the dates from moving.

[0025] Working Principle: Jujube Conveying: Motor 301 drives the first pulley 302 to rotate, which in turn drives the jujube conveyor belt 303. The jujube conveyor belt 303 then drives the second pulley 304, allowing the jujubes to enter from the calibration inlet 41. Under the limit of the limiting slot frame 4, the jujubes are smoothly conveyed along the jujube conveyor belt 303. Jujube Fixing: When the jujubes are conveyed to the area below the soft pressing rod 62, the soft pressing rod 62 presses down, pressing and fixing the jujubes onto the jujube conveyor belt 303 to prevent the jujubes from shifting during pitting. Pitting Operation: The electric telescopic rod 51 pushes the ejector pin 52 forward. The ejector pin 52 passes through the jujube and pushes the pit into the waste discharge sleeve 61 for discharge, completing the pitting process. Discharge: The pitted jujubes continue to move with the jujube conveyor belt 303 and are finally discharged from the device from the discharge port 42, completing the entire pitting process.
