Description

Technical Field

[0001] This utility model relates to the technical field of egg packaging equipment, specifically to an egg receiving claw. Background Technology

[0002] In the packaging stage of egg processing, the receiving claw of the egg stacking machine is one of the core components. Its main function is to receive eggs falling from the egg cup and place them stably on the egg tray. Most existing receiving claws are integrated, fixed structures, such as the receiving claw in the hatching egg packaging device disclosed in patent CN211568396U, and the egg receiving component in a novel egg packaging device disclosed in patent CN204871710U. During long-term use, the part of the claw that comes into contact with the eggs will gradually wear down due to continuous friction.

[0003] As wear and tear increases, the diameter of the claws decreases, and the gap between the two claws widens, making it difficult to stably hold the egg. This not only causes the egg to fall directly, resulting in waste, but the falling egg may also damage other eggs already placed in the egg tray, causing secondary losses.

[0004] Meanwhile, egg-packing machines typically have a large number of receiving claws. In existing technology, once worn out, the entire receiving claw needs to be replaced. This is not only expensive to purchase a single claw, but also time-consuming. After replacement, the packaging equipment needs to be readjusted, severely impacting production efficiency and increasing the company's operating costs and downtime losses. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of easy wear, high replacement cost, and reduced production efficiency of existing egg receiving claws, and to provide an egg receiving claw with a simple structure, extended service life, and easy maintenance.

[0006] To achieve the above objectives, this utility model provides an egg receiving claw, including a receiving claw body. The receiving claw body includes a main body and two claw body parts rotatably connected to the main body, and an egg-gripping space for receiving eggs is formed between the two claw body parts.

[0007] The main body has a circular groove that fits the claw body, and part of the claw body is inserted into the circular groove. The main body also has an internal threaded hole that communicates with the circular groove. A set screw is installed in the internal thread of the internal threaded hole. The claw body is pressed and fixed in the circular groove by the set screw, so as to realize the detachable and fixed claw body.

[0008] The claw body has a rotating structure and is divided into a narrow diameter section and a coaxial coaxial section: the narrow diameter section is inserted into a circular groove and is used to connect with the main body; the coarse diameter section is used to contact the egg and form the main contact section of the egg clamping space.

[0009] An annular groove is provided on the narrow diameter section. One end of the set screw passes through the circular groove and extends into the annular groove, which can prevent the claw body from moving axially and ensure the structural stability during rotation adjustment.

[0010] To further prevent direct wear on the claw body, an elastic buffer sleeve is fitted onto the coarse diameter section. The elastic buffer sleeve is made of low-cost elastic plastic tubing and is used to replace the coarse diameter section in direct contact with the egg during use.

[0011] One end of the elastic buffer sleeve is provided with a concave flange, which abuts against the shoulder formed at the junction of the large diameter part and the small diameter part, so as to realize the axial positioning of the elastic buffer sleeve and prevent it from axially shifting during use.

[0012] The main body is provided with a hinge hole for rotating the receiving claw body to the execution mechanism of the egg stacking machine, so as to ensure that the receiving claw can complete the egg receiving and placing actions as the equipment moves.

[0013] The main body is also equipped with counterweight mounting holes, which can be used to adjust the center of gravity of the receiving claw by installing counterweight blocks, thereby improving its stability during the egg receiving and placing process.

[0014] The beneficial effects of this technical solution are as follows: By rotating the claw body and the main body, when the claw body is partially worn, it can be rotated to adjust its contact position with the egg, so that the wear is evenly distributed, greatly extending the overall service life of the receiving claw and reducing the number of times the whole claw needs to be replaced.

Detailed Implementation

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] Please see Figures 1 to 3 This application provides an egg receiving claw, including a main body 1 and two claw bodies 2. Both claw bodies 2 are rotatably connected to the main body 1, and a clamping space for receiving eggs is formed between the two claw bodies 2. The claw bodies 2 are made of food-grade, high-wear-resistant POM.

[0018] Two symmetrical circular grooves 11 are provided on the main body 1, and an internal threaded hole 12 is provided next to each circular groove 11. The internal threaded hole 12 is connected to the circular groove 11 and is set perpendicular to the circular groove 11. A hinge hole 13 is provided in the middle of the main body 1 for hinge connection with the egg stacking machine's execution arm. A counterweight mounting hole 14 is provided at the other end for installing a metal counterweight block as needed.

[0019] The claw body 2 is a rotating structure, comprising a narrow diameter portion 21 and a wide diameter portion 22. The diameter of the narrow diameter portion 21 is smaller than that of the wide diameter portion 22. The diameter of the narrow diameter portion 21 is adapted to the inner diameter of the circular groove 11. An annular groove 211 is machined on the narrow diameter portion 21. The narrow diameter portions of the two claw bodies 2 are respectively inserted into the two circular grooves 11, so that the annular groove 211 is aligned with the internal threaded hole 12. Then, the set screw 3 is screwed into the internal threaded hole 12 until the end of the set screw 3 extends into the annular groove 211. This can achieve axial positioning of the claw body 2 and prevent the claw body 2 from detaching from the main body 1. After the set screw 3 presses the annular groove 211, the claw body 2 is completely fixed, restricting the rotation and axial movement of the claw body 2. At this time, a clamping space is formed between the wide diameter portions 22 of the two claw bodies 2.

[0020] When in use, if the area of ​​the coarse diameter part 22 that contacts the egg is worn, the set screw 3 can be loosened, the claw body 2 can be rotated to align the unworn area with the area that can contact the egg, and then the set screw 3 can be tightened to continue use. There is no need to replace the entire receiving claw, which effectively extends the service life.

[0021] In some embodiments, please refer to Figures 4 to 6 Furthermore, an elastic buffer sleeve 4 can be added based on the above embodiments. The elastic buffer sleeve 4 is made of elastic plastic tube, such as food-grade low-density polyethylene. Its inner diameter is adapted to the diameter of the coarse diameter portion 22 of the claw body portion 2. The elastic buffer sleeve 4 is fitted onto the coarse diameter portion 22. One end of the elastic buffer sleeve 4 is machined with a concave flange 41.

[0022] During installation, the elastic buffer sleeve 44 is fitted onto the coarse diameter portion 22, so that the concave edge 41 of the elastic buffer sleeve 4 abuts against the shoulder 23 between the coarse diameter portion 22 and the fine diameter portion 21, thereby achieving axial fixation of the elastic buffer sleeve 4; during use, the elastic buffer sleeve 4 directly contacts the egg, avoiding direct wear on the surface of the claw portion 2.

[0023] When the elastic buffer sleeve 4 is worn, the set screw 3 can be loosened, the claw body 2 can be rotated so that the unworn area of ​​the elastic buffer sleeve 4 is aligned with the area that can contact the egg, and then the set screw 3 can be tightened to continue use. There is no need to replace the entire elastic buffer sleeve 4, which effectively extends its service life.

[0024] After the elastic buffer sleeve 4 wears out evenly, it needs to be replaced as a whole. Simply loosen the set screw 3 so that the set screw 3 is away from the ring groove 211, and the claw body 2 and the elastic buffer sleeve 4 can be removed. Then, a new buffer sleeve can be replaced. The cost of a single elastic buffer sleeve 4 is much lower than that of the whole receiving claw, and the replacement process does not require equipment debugging, which greatly reduces maintenance costs and downtime.
