Description

Technical Field

[0001] This invention belongs to the field of pig hair removal technology, specifically relating to a black pig hair removal device. Background Technology

[0002] Pig hair removal is an essential step in pig slaughtering and processing. Currently, pig hair removal machines are commonly used. Pigs, scalded in boiling water, are placed in a hair removal box. Rotating rollers within the box cause the pig to roll, while scrapers on the rollers at a fixed speed directly scrape away the hair. However, black pigs have coarse, deep-rooted bristles, making it difficult for conventional hair removal equipment to effectively remove them. Forcibly extending the scraping time can easily scratch the pig's skin, affecting hair removal efficiency and subsequent processing quality. Summary of the Invention

[0003] Based on the problems mentioned in the background art above, the present invention provides a black pig hair removal device to solve the problem that current pig hair removal devices are unable to effectively remove coarse and deeply rooted black pig hair.

[0004] The technical solution adopted in this invention is as follows:

[0005] A black pig hair removal device includes a hair removal box, a drive box, and a control box. The hair removal box contains a pig support frame and a hair removal roller. The hair removal box includes a base frame and box panels, and has a feed inlet. A feed support frame is mounted on the base frame. The feed support frame and the hair removal roller are both connected to the drive box. Linkage frames are mounted on the box panels on both sides of the base frame, and the linkage frames are connected to telescopic rods. Push rollers are mounted on the linkage frames. The box panels have reserved slots for the movement of the push rollers. The hair removal roller includes a rotating shaft and several hair removal devices mounted on the rotating shaft. The rotating shaft is rotatably mounted... The hair removal device is mounted on a base frame and connected to a drive box. It includes a base connected to a rotating shaft, and a scraping plate and a mounting plate are installed on both sides of the base. The top of the mounting plate has a mounting groove, and a force-applying component and a hair-clamping component are installed in the mounting groove. The force-applying component includes an integrally formed first mounting part, a hook plate, and a support plate. The first mounting part is hinged in the mounting groove. The hair-clamping component includes a second mounting part and a hair-clamping part. When the support plate is pressed down, the hook plate squeezes the second mounting part to rotate, causing the front end of the hair-clamping part to fit against the hair-clamping part. The support plate faces the opposite direction to the rotation direction of the hair removal roller.

[0006] Using the above technical solution, the feeding tray rotates to feed the scalded black pigs into the dehairing box. Inside the box, the pigs roll under the action of the dehairing rollers and are dehaired by the dehairing device. As the dehairing device rotates with the shaft, the pig hair is first scraped by the scraping plate. Some pig hair enters between the scraping plate and the clamping component. As the dehairing device moves, the pig's own weight acts on the force-applying component, causing the clamping component to move and clamp the pig hair against the scraping plate. With continuous rotation, the force-applying component is continuously pressed down by gravity, keeping the clamping component in contact with the scraping plate. The rotation gradually moves the clamping component away from the pig's skin surface, allowing the clamped pig hair to be pulled out. This method of hair removal is easier than traditional scraping, and is more suitable for dehairing black pigs with deep hair roots. Furthermore, the dehairing roller is equipped with several dehairing devices, maintaining high dehairing efficiency.

[0007] Based on the above technical solution, the present invention has made the following improvements:

[0008] Furthermore, a notch is provided at the bottom of the first mounting part, and a tension spring is installed at the bottom of the second mounting part. The tension spring passes through the notch and connects to the mounting plate. After the second mounting part and the mounting plate are connected by the tension spring, the hair clamping part can automatically reset after being pressed by external force, so that it can continue to be used to clamp pig hair.

[0009] Furthermore, the surface of the support plate is provided with anti-slip toothed strips. This increases the frictional resistance of the support plate surface, making it less likely for the pigskin to slip off the support plate during rotation.

[0010] Furthermore, the support plate is arc-shaped, and the center of the arc coincides with the axis of rotation. When the support plate is in a free state, the circle containing its top surface is the circumcircle of the top of the scraping plate. After the support plate is pressed down, it remains in a relatively stable pressed state as it rotates with the axis, so that the clamping parts can stably grip the scraping plate.

[0011] Furthermore, when the tension spring is in its initial state, the distance between the front end of the hair-clamping part and the hair-scraping plate is 1-2 cm. This allows the pig hair to fall more easily into the area between the front end of the hair-clamping part and the hair-scraping plate, thus facilitating better hair clamping.

[0012] Furthermore, a drive motor is mounted on the linkage frame in the drive box, and the drive motor is connected to the push roller. The push roller is rotatable to facilitate the easy ejection of the dehaired pig from the dehairing box.

[0013] Furthermore, the pig support frame includes several longitudinal beams arranged at an incline, with each dehairing roller's dehairing device located between corresponding beams. The beams contain only steam pipes with their outlets facing upwards, and these pipes are connected to a steam source. The steam source is used to generate steam, which is then sprayed onto the pig's skin during the dehairing process, keeping the skin surface hot and facilitating hair removal.

Detailed Implementation

[0023] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] like Figures 1 to 7 As shown, a black pig hair removal device includes a hair removal box, a drive box 2, and a control box 21. The hair removal box is equipped with a pig support frame 4 and a hair removal roller 5. The hair removal box includes a base frame 1 and a box plate 11. The hair removal box is equipped with a feed inlet 12. A feed support frame 22 is installed on the base frame 1. The feed support frame 22 and the hair removal roller 5 are both connected to the drive box 2 for transmission. By driving the feed support frame 22 to rotate, the black pigs that have been scalded by boiling water can be sent into the hair removal box. The black pigs enter the hair removal box and are rolled by the action of the hair removal roller 5, and are hair removed by the hair removal device 52.

[0025] Both sides of the base frame 1 have a linkage frame 31 installed on the box plate 11. The linkage frame 31 is connected to a telescopic rod 32, and a push roller 3 is installed on the linkage frame 31. The box plate 11 has a reserved groove 13 for the movement of the push roller 3. The telescopic rod 32 can pull the linkage frame 31 to rotate, causing the push roller 3 to descend and push the hairless black pig out of the hair removal box. The linkage frame 31 in the drive box 2 is equipped with a drive motor, which is connected to the push roller 3. The push roller 3 can rotate to easily push the hairless pig out of the hair removal box.

[0026] like Figures 3-7As shown, the hair removal roller 5 includes a rotating shaft 51 and a plurality of hair removal devices 52 disposed on the rotating shaft 51. The rotating shaft 51 is rotatably mounted on the base frame 1 and is connected to the drive box 2 for transmission. The hair removal device 52 includes a base 521 connected to the rotating shaft 51. A scraping plate 522 and a mounting plate 523 are installed on both sides of the base 521. The scraping plate 522 can be used for scraping hair. The top of the mounting plate 523 has a mounting groove 53. A force-applying component 54 and a hair-clamping component 55 are installed in the mounting groove 53. The force-applying component 54 includes an integrally formed first mounting part 541, a hook plate 542, and a support plate 543. The support plate 543 faces the opposite direction to the rotation direction of the hair removal roller 5. The first mounting part 541 is hinged in the mounting groove 53. The hair-clamping component 55 includes a second mounting part 551 and a hair-clamping part 552. When the support plate 543 is pressed down, the hook plate 542 squeezes the second mounting part 551 to rotate, thereby causing the front end of the hair-clamping part 552 to fit together and clamp the pig hair between the front end of the hair-clamping part 552 and the hair removal plate 522. In order to make it easier for the pig hair to fall into the area between the front end of the hair-clamping part 552 and the hair removal plate 522, the distance between the front end of the hair-clamping part 552 and the hair removal plate 522 is 1-2 cm when the tension spring 56 is in the initial state.

[0027] As the force-applying component 54 continues to rotate, it is continuously pressed down by gravity, causing the hair-clamping component 55 to remain in contact with the hair-scraping plate 522. The rotation allows the closed area between the hair-clamping component 55 and the hair-scraping plate 522 to gradually move away from the pig's skin surface, thereby pulling out the clamped pig hair.

[0028] like Figure 6 As shown, the first mounting part 541 has a notch 544 at the bottom, and the second mounting part 551 has a tension spring 56 installed at the bottom. The tension spring 56 passes through the notch 544 and is connected to the mounting plate 523. After the second mounting part 551 and the mounting plate 523 are connected by the tension spring 56, the hair clamping part 55 can be reset by itself after being pressed by external force, so that it can continue to be used to clamp pig hair.

[0029] like Figure 4 , Figure 5 As shown, the surface of the support plate 543 is provided with anti-slip teeth. This increases the frictional resistance of the support plate 543 surface, making it less likely for the pigskin to slip off the support plate 543 during rotation. The support plate 543 is arc-shaped, and the center of the arc of the support plate 543 coincides with the axis of the rotating shaft 51. When the support plate 543 is in a free state, the circle containing the top surface is the circumcircle of the top of the scraping plate 522. After the support plate 543 is pressed down, it can remain in a relatively stable pressed state during the rotation of the rotating shaft 51, so that the hair clamping part 55 can stably bite the scraping plate 522.

[0030] like Figure 3As shown, the pig support frame 4 includes several longitudinal beams 42 inclinedly arranged crossbeams 41. The hair removal devices 52 on each hair removal roller 5 are located between the corresponding crossbeams 41. There are only steam pipes inside the crossbeams 41. The outlet end of the steam pipe is upward. A steam source is connected to the outside of the steam pipe. The steam source is used to blow steam into the air. During the hair removal process, the steam is blown onto the skin of the black pig, which can keep the skin surface hot and make it easier to remove hair.

[0031] In use, the scalded black pig is placed on the feeding tray 22. The driving component in the drive box 2 drives the feeding tray 22 to rotate, feeding the black pig into the dehairing box. After the black pig enters the dehairing box, it rotates counterclockwise (e.g., ...). Figure 4 The dehairing roller 5 (as shown) pushes the black pig to roll, while the scraping plate 522 scrapes off the hair. Some pig hair enters between the scraping plate 522 and the hair clamping part 55. As the dehairing device 52 moves counterclockwise, the pig's own weight acts on the support plate 543, and the hook plate 542 squeezes the second mounting part 551 to rotate, thereby causing the front end of the hair clamping part 552 to fit against the hair clamping part 552 and clamp the pig hair between the front end of the hair clamping part 552 and the scraping plate 522 (such as...). Figure 7 As shown, with continuous rotation, the support plate 543 is continuously pressed downwards by gravity, causing the hair-clamping component 55 to remain in contact with the scraping plate 522. Continuous rotation allows the closing point between the hair-clamping component 55 and the scraping plate 522 to gradually move away from the pig's skin surface, thus removing the clamped pig hair. As the hair removal device 52 continues to move, the support plate 543 will detach from the pressure of the black pig and will reset under the action of the tension spring 56 (as shown). Figure 6 Next, immerse the pig carcass, which has already had most of its coarse hair removed, in a 200℃ molten food rosin and lard mixture to quickly coat it with a layer of adhesive. Immediately rinse it with cold water; the thermal expansion and contraction will cause the rosin to solidify into a film. Then, peel off the solidified film from the surface of the carcass to remove any remaining pig hair, as well as the fine black hairs and hair roots stuck together in the pores. This completes the hair removal process. Finally, rinse the carcass with clean water.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
