Description

Technical Field

[0001] This utility model relates to an egg cutter, and more particularly to a semi-automatic egg cutter. Background Technology

[0002] In the food processing industry, especially in catering, food factories, and central kitchens, large quantities of cooked poultry eggs (such as chicken eggs, duck eggs, and quail eggs) are frequently processed and cut into uniform slices or halves for use in salads, platters, dish garnishes, or other prepared foods. Traditional manual egg-cutting methods rely primarily on knives and cutting boards, which are not only inefficient and labor-intensive but also pose risks such as uneven slice thickness, egg breakage, hygiene hazards (e.g., hand contact), and potential knife cuts for operators. With rising labor costs and increasing demands for food standardization and safety, traditional methods are no longer sufficient to meet the needs of large-scale production. Existing technologies, such as CN209920004U, disclose an egg-cutting machine that uses an egg holder on a conveyor chain to transport eggs to a cutting mechanism at the rear of the chain for cutting. While this overcomes the shortcomings of manual cutting, it still suffers from the following major technical defects: 1. During cutting, yolk and albumen fragments easily adhere to the blade surface, lacking effective online cleaning methods, leading to decreased cutting quality, increased hygiene risks, and frequent machine shutdowns for cleaning; 2. Insufficient positioning accuracy of the egg holder when transported to the cutting station, and lack of effective locking at the moment of cutting, easily causing egg displacement or crushing, affecting product qualification rate; 3. Cut egg pieces may stick to the egg holder, and without a detection mechanism, they are prone to unplanned falling, resulting in waste and contamination; 4. Stubborn residues in the grooves of the support plate and blade seams are difficult to clean, lacking an integrated cleaning design, resulting in a large maintenance workload. Therefore, there is an urgent need to develop a new type of semi-automatic egg-cutting equipment that can efficiently cut while focusing on solving key technical problems such as blade self-cleaning, precise positioning and locking of the support plate, residue detection, and easy cleaning of the entire machine.

[0028] The conveyor chain 2 adopts a double chain drive. The conveyor chain 2 is driven by the motor 3 to move intermittently. The support plate 4 is detachably installed on the conveyor chain 2 by bolts at equal intervals, which is convenient for replacement and maintenance. The support plate 4 is long and strip-shaped. Multiple egg grooves 41 adapted to the shape of poultry eggs are evenly arranged side by side on the surface of the support plate 4. Each egg groove 41 has a lower cutting groove 42 that penetrates the support plate 4 along the conveying direction of the conveyor chain 2 in the middle.

[0029] The cutting mechanism 5 includes a cutting frame 52, a cutting base 53, and a drive cylinder 54. The cutting frame 52 is fixed horizontally above the frame 1. The cylinder body of the drive cylinder 54 is fixed to the top of the cutting frame 52, and its piston rod is connected downward to the cutting base 53. The cutting base 53 is slidably connected to the cutting frame 52 through a guide rail to ensure smooth movement. The cutting blade 51 is fixed to the bottom of the cutting base 53 by bolts, and its position corresponds one-to-one with the egg groove 41 on the support plate 4. The lower side of the cutting base 53 is also connected to the upper mold base 56 through a slide rod 55. A return spring 57 is sleeved between the cutting base 53 and the upper mold base 56 through the slide rod 55. The lower surface of the upper mold base 56 is provided with an upper mold groove 58 that matches the egg groove 41, which is used to press down the poultry egg from above to prevent it from rolling during cutting. The middle of the upper mold groove 58 is provided with an upper cutting edge 59 for the cutting blade 51 to pass through.

[0030] A first sensor 11 (such as a photoelectric sensor) is provided on the side of the frame 1 near the input end of the conveyor chain 2. A sensing head 43 (such as a protrusion) matching the first sensor 11 is provided on the outer side of the support plate 4 to determine whether the support plate 4 has reached the predetermined starting position. Positioning holes 44 are also provided on both sides of the support plate 4. Positioning cylinders 12 are provided on both sides below the cutter 51 on the frame 1. The piston rod end of the positioning cylinder 12 is provided with a wedge-shaped positioning rod 13 that can be inserted into the positioning hole 44. After insertion, the radial component force generated by the wedge surface is used to firmly fix the support plate 4, so as to achieve reliable locking.

[0031] The scraping mechanism 6 is integrated on the upper mold base 56. The scraping mechanism 6 includes a scraper 61 slidably disposed on the upper side of the upper mold base 56 and a scraping cylinder 62 for driving the scraper 61 to slide. The scraper 61 has a scraping groove 63 on the side facing the cutter 51 that matches the thickness of the cutter 51. The scraping groove 63 can be inserted into and fit against the two sides of the cutter 51 to scrape off the residue. The upper mold base 56 also has a sliding groove 64. The scraper 61 is slidably embedded in the sliding groove 64 on the top of the upper mold base 56 by the slider at its bottom. The cylinder body of the scraping cylinder 62 is fixed to one side of the upper mold base 56, and its piston rod is connected to the scraper. The plate 61 is connected, and the chute 64 is provided with a rear scraper 65 that can push the residue scraped off the scraper 61 into the chute 64. When the controller 8 issues a scraping command, the scraping cylinder 62 pushes the scraper 61 to move laterally, so that the scraper 63 is precisely fitted into the two sides of the cutter 51 to scrape off the attached material. When the scraper 61 finishes scraping and resets in the reverse direction, the rear scraper 65 pushes all the residue accumulated in front of the scraper 61 into the chute 64. When the scraper 61 scrapes again, it pushes the residue to the collection area at the end of the chute 64, realizing automatic collection of residue and facilitating centralized cleaning.

[0032] The frame 1 is equipped with a second sensor 14 and a matching sensing plate 15 at the output end of the conveyor chain 2. The sensor 14 is used to detect whether there are residual eggs in the support plate 4 and control the start and stop of the conveyor chain 2. When the cut egg slices are not removed from the support plate 4, they will block the light beam. The second sensor 14 sends a signal, and the controller 8 will stop the motor 3 until manual intervention is required to remove them.

[0033] The frame 1 has a spraying mechanism 7 on the lower part of the output end of the conveyor chain 2. The spraying mechanism 7 includes several high-pressure spray pipes 71 arranged horizontally on the lower side of the conveyor chain 2. The nozzles of the high-pressure spray pipes 71 are aligned upward with the returning empty support plate 4. A water collection tank 72 is provided below the high-pressure spray pipes 71 for receiving and guiding cleaning wastewater.

[0034] Its basic workflow is as follows: The operator manually places cooked poultry eggs (such as chicken eggs) into the egg slot 41 of the support plate 4 at the input end. The conveyor chain 2, driven by the motor 3, intermittently sends the support plate 4 carrying poultry eggs to the cutting station. Upon arrival, the first sensor 11 and the sensing head 43 cooperate to achieve coarse positioning. Then, the positioning cylinder 12 is activated to insert the wedge-shaped positioning rod 13 into the wedge-shaped positioning holes 44 on both sides of the support plate 4 to achieve precise positioning and locking. Afterward, the drive cylinder 54 of the cutting mechanism 5 drives the cutting base 53 and the cutting blade 51 to move downward. In the initial stage of downward movement, the scraper 61 of the scraping mechanism 6... First, the cutter 51 is inserted to scrape off the residue from the previous operation on both sides and then resets. The cutter 51 continues to descend, passing through the upper cutting edge 59 of the upper mold base 56, and finally penetrating the lower cutting groove 42 of the support plate 4, completing the one-time cutting of all the eggs in the egg tray 41. After the cutting is completed, the cutter 51 moves upward and resets, the positioning cylinder 12 retracts and releases the lock, the conveyor chain 2 starts, and sends the support plate 4 with the cut egg slices to the output end. At the output end, the second sensor 14 detects whether there is any residue in the support plate 4. If there is, the egg slices are manually removed, and the empty support plate 4 continues to run to the bottom, is rinsed by the spray mechanism 7, and then returns to the input end, completing one cycle.
