Description

Technical Field

[0001] The utility model belongs to the field of pork depilation, and particularly relates to an online rosin dipping device. Background Art

[0002] Chinese people have a special fondness for pig heads, and they consume a large amount of them. However, if the pig heads are not cleanly processed during the braising process, residual pig hair will significantly affect the quality and appearance of the product. Using a knife to scrape the hair will leave stubble inside the pig skin, which will significantly affect the taste after braising. Using rosin can completely remove the stubble inside the skin, significantly improving the taste and appearance. Currently, pig heads are processed in slaughterhouses by passing the pig carcasses through DT500. After the pig heads are cut off, they are manually dipped in rosin and plucked twice in the head, hoof and tail processing room. Due to the multiple spraying processes on the slaughtering line, the temperature of the pig heads has dropped and the pores have shrunk. Moreover, the pig heads have been passed through the singeing furnace, leaving only residual stubble in some pig hair. Rosin is not very effective in plucking hair. Even after shaving, some hair roots still remain in the pig heads, affecting product quality. After several sprayings in the slaughtering production line, the temperature of the pig heads has dropped, the pores have shrunk, and the pig heads have passed through the singeing furnace, leaving only residual stubble on some of the pig hair. The rosin plucking effect is poor, and even after shaving, some hair roots still remain in the pig heads, affecting product quality.

[0003] Patent CN214015748U provides an online pig head dehairing device. However, the head conveyor in the patent requires the pig heads to be moved along the production line, through the rosin pool and cooling pool, while also descending for immersion and ascending for removal. This requires modifications to the slaughtering line, which is labor-intensive, complex, and expensive. A simpler online rosin dipping device is needed. Summary of the Invention

[0022] The following will combine the accompanying drawings and specific embodiments to clearly and completely describe the technical solution of the present invention. Figure 1-8As shown, an online rosin dipping device includes a small rosin pool 1 set on the slaughtering line, and the slaughtered object 2 being transported passes over the small rosin pool 1. The device is characterized by: further including a lifting mechanism, which drives the small rosin pool 1 to rise or fall so that the slaughtered object 2 enters the small rosin pool 1 for dipping in rosin and leaves the small rosin pool 1. The small rosin pool 1 of the utility model can adopt the existing rosin pool structure and can include functions such as heating and heat preservation. Except for the structure of the lifting mechanism, the structure of the small rosin pool 1 can adopt the existing technology and will not be described in detail. When the slaughtered object 2 passes over the small rosin pool 1, the small rosin pool 1 rises and the slaughtered object 2 is dipped in rosin. After dipping, the small rosin pool 1 descends, and the slaughtered object 2 moves to the next position for manual spraying and plucking. The utility model has a simple structure and can conveniently perform the rosin dipping operation. The lifting mechanism can adopt existing common lifting mechanisms, such as crank slider mechanism, winch mechanism, cylinder drive, gear rack mechanism and other existing technologies.

[0023] The apparatus further includes a large rosin pool 3 disposed on the ground below the small rosin pool 1. The small rosin pool 1 is driven up and down by the lifting mechanism to slide within the large rosin pool 3. When the small rosin pool 1 is in a low position, liquid in the large rosin pool 3 enters the small rosin pool 1. When the small rosin pool 1 is in a high position, the upper surface of the small rosin pool 1 is higher than the upper surface of the large rosin pool 3. In all embodiments including both the large rosin pool 3 and the small rosin pool 1, the sidewalls and bottom wall of the large rosin pool 3 may include a hollow interlayer, within which heat transfer oil is disposed. The heat transfer oil in the interlayer heats and maintains the heat of the rosin liquid in the large rosin pool 3 by dissipating heat. An oil tank 13 is disposed outside the large rosin pool 3. A heating wire is provided within the oil tank 13 to heat the heat transfer oil therein. The oil outlet of the oil tank 13 is connected to the oil inlet of the interlayer via a pipeline and a pump. The oil inlet of the oil tank 13 is also connected to the oil outlet of the interlayer via a pipeline, thereby enabling circulation of the heat transfer oil. The large rosin pool 3 can also adopt the structure of the rosin pool in the existing technology, such as the reference document patent CN214015748U and other existing structures, and the small rosin pool 1 is only responsible for taking liquid from the large rosin pool 3 and dipping the slaughtered object 2. The small rosin pool 1 takes liquid from the large rosin pool 3. When the small rosin pool 1 is at a high position, the slaughtered object 2, such as a pig's head, enters the small rosin pool 1 to dip in the liquid. The small rosin pool 1 of the utility model is convenient for taking liquid, and the liquid overflowing from the small rosin pool 1 during the dipping process can fall into the large rosin pool 3, avoiding waste. In addition, the utility model only lifts the small rosin pool 1, because the small rosin pool 1 is lighter than the large rosin pool 3 and is not connected to structures such as heating, the structure of lifting the small rosin pool 1 is simpler, low-cost and not easy to damage.

[0024] The lifting mechanism includes a fixed frame 4 positioned above the small rosin reservoir 1. An output shaft 7 driven for rotation by a driving mechanism 5 is mounted on the fixed frame 4. Two rotating disks 6 are fixed to the output shaft 7. Each rotating disk 6 is hingedly mounted at a predetermined distance eccentric from the center of the circle, with the lower end of each rocker 8 hinged to a corresponding side surface of the small rosin reservoir 1. A guide and limiting mechanism is provided between the small rosin reservoir 1 and the large rosin reservoir 3 to ensure that only the small rosin reservoir 1 moves up and down. The rotating disks 6, rocker 8, small rosin reservoir 1, and large rosin reservoir 3 form a slider-crank mechanism. The driving mechanism 5 may include a motor reducer mounted on the fixed frame 4, a sprocket mounted on the motor shaft, and a sprocket also mounted in the middle of the output shaft 7. A chain connects the motor sprocket and the output shaft sprocket 7, driving the output shaft 7 to rotate. The output shaft 7 is rotatably mounted on the fixed frame 4 via two bearings. A rotating disk 6 is fixed to each end of the output shaft 7. A crank can also be provided on the output shaft 7 in place of the rotating disk 6. In addition, existing lifting mechanisms are also within the protection scope of the present invention.

[0025] The guide and limiting mechanism includes guide plates 9 positioned above two opposing sides of the small rosin pool 1. Each guide plate 9 is fixedly connected to the corresponding side of the small rosin pool 1. The guide plates 9 are hingedly connected to the rocker 8. Tracks 10 are provided on the left and right sides of each guide plate 9 corresponding to the large rosin pool 3. Rotating rollers 91 are provided on the guide plates 9 at positions corresponding to the tracks 10. The tracks 10 and rollers 91 are in rolling contact and are limited in the forward and backward directions by grooves. The left and right positions of the guide plates 9 are limited by the distance between the left and right tracks 10 on the same side. The guide plates 9 are limited in the forward and backward directions by grooves. The tracks 10 may be provided with grooves within which the rollers 91 move, or the rollers 91 may be provided with grooves on their circumferential surfaces, with the tracks 10 positioned within the grooves. Upward-facing connecting rods 11 are fixedly provided at the upper ends of the front and rear sides of the small rosin pool 1, with at least two connecting rods 11 provided on each side. The guide plates 9 are welded to the upper ends of the connecting rods 11 on the same side. Preferably, when the small rosin pool 1 is at its lowest position, the guide plate 9 is above the height of the rosin liquid level. The track 10 can be arranged on the side of the large rosin pool 3, can be arranged inside the large rosin pool 3, or can be arranged outside the large rosin pool 3, as required. In the structure of the accompanying drawings, the track 10 is arranged in the roller 91 groove of the roller 91 and is in rolling contact with the roller 91. The guide plate 9 can include two parallel guide connecting plates 90, the four corners of the guide connecting plates 90 respectively pass through the rollers, and the roller 91 is arranged in the middle of the rollers; the rollers are provided with threads at both ends of the guide plates 9, and bolts are provided on the threads to limit the axial movement of the rollers. If the rollers are rotatably connected to the guide plates 9, then the rollers and rollers 91 can be arranged as one piece; if the rollers are fixed between the two guide connecting plates 90, then the rollers 91 are rotatably arranged on the rollers. The guide plate 9 can also be a single plate with grooves cut at the four corners, with the roller passing through both sides of the grooves, and a roller 91 provided in the middle of the roller. Threads are provided at both ends of the roller extending from the guide plate 9, and bolts are provided on the threads to limit the axial movement of the roller. Other guide and limiting mechanisms, such as guide rail and slider mechanisms, and structures provided with sliders on the guide plate 9 are also within the scope of protection of the present invention.

[0026] A spray mechanism 12 is positioned adjacent to and in front of the large rosin pool 3, along the conveying direction of the slaughtered animal 2. The width of the large rosin pool 3 extends in the conveying direction of the slaughtered animal 2. The spray mechanism 12 comprises a water pipe connected to a water source, equipped with a nozzle that sprays cooling water toward the slaughtered animal 2. After being dipped in rosin, the slaughtered animal 2 moves forward to the spray mechanism 12 for cooling. After cooling, the animal can be manually plucked.

[0027] Along the conveying direction of the slaughtered object 2; a singeing furnace is arranged in front of the spraying mechanism 12. The utility model can automatically dip the pig head of each pig into rosin online without affecting the speed of the production line. An online rosin dipping device is installed in front of the singeing furnace. When the pig carcass just comes out of the hair removal machine and the pig hair has not been burned into stubble by the singeing furnace and the pores are expanded, the pig head is plucked with rosin in advance. The test shows that the effect is more obvious than that of the head, hoof and tail processing room after dehairing. At the same time, plucking the hair in front of the singeing furnace can remove the hair on the pig head, trough head and pig hoof at one time, which improves the quality of the head and hoof and is also beneficial to the quality control of pig raw materials.

[0028] In practice, the slaughtered animal 2 stops when passing over the large rosin pool 3. The drive mechanism 5 rotates the output shaft 7, which in turn drives the two rotating disks 6 on the output shaft 7, which then swing the rocker 8 up and down. The small rosin pool 1 is moved upward along the length of the track 10 by the rocker 8 until the pig's head is immersed in the rosin. After being dipped in rosin, the drive mechanism 5 lowers the lower rosin pool into the large rosin pool 3. The slaughtered animal 2 is then moved to the spray wheel mechanism for cooling, followed by manual or mechanical plucking. Other plucking procedures can be selected as needed.

[0029] The technical features of the above-described embodiments may be combined in any manner, and as long as there are no contradictions in the combination of these technical features, they shall be deemed to be within the scope of this specification. Without departing from the overall concept of the present invention, the technical solutions of the present invention, their equivalent replacements or modifications, and certain changes and improvements made thereto shall also be deemed to be within the scope of protection of the present invention.
