[0024] Example:

[0025] A reciprocating swing mechanism 4 for scalding pig hair is provided. The swing mechanism 4 is used in conjunction with a scalding tank 1 to scald the pig hair. The scalding tank 1 is trough-shaped and includes an inlet end and an outlet end. Hot water is contained in the scalding tank 1. Under the action of external force, the pig moves from the inlet end to the outlet end to complete the scalding of the pig hair, which facilitates the next step of removing the pig hair. The swing mechanism 4 includes a support frame 5, a drive device, a front roller 41, a rear roller 42, and a swing assembly. Both ends of the front roller 41 and the rear roller 42 are equipped with rollers 43. The rollers 43 are used to move on the hot water tank 1. The front roller 41 and the rear roller 42 are mounted on the support frame 5. At least two pusher frames 2 are also mounted on the support frame 5. The swing assembly includes a swing arm 44, a swing connecting rod 45, a connecting rod fixing seat 46, and a crossbeam 47. One end of the swing arm 44 is connected to the drive device, which drives the swing arm 44 to rotate. The other end of the swing arm 44 is hinged to the swing connecting rod 45. Both ends of the swing connecting rod 45 are hinged to the swing arm 44 and the connecting rod fixing seat 46, respectively. The crossbeam 47 is fixedly connected to the hot water tank 1. The connecting rod fixing seat 46 is mounted on the crossbeam 47. The drive device is mounted on the support frame 5. The drive device drives the swing arm 44 to perform circular motion, causing the support frame 5 to reciprocate above the hot water tank 1. The pigs sway back and forth between two pusher frames 2, creating flow between the water and the pigs, which allows for better scalding of the pig hair. This achieves automatic swaying of the pigs in the scalding tank 1, replacing the traditional process of manually pulling the pigs back and forth. The drive device includes a motor 51 and a reducer 52. The motor is connected to the input shaft of the reducer, which includes a first output shaft and a second output shaft; the second output shaft is connected to the swing arm 44.

[0026] Preferably, the swing mechanism 4 further includes a roller 43 groove; the roller 43 groove is disposed on the hot water tank 1; the roller 43 is disposed within the roller 43 groove. This design prevents derailment during the swinging process, increasing safety.

[0027] In one possible embodiment, a pushing component is also included; the pushing component includes a sprocket and a pushing chain 33; the sprocket includes a first sprocket 31 and a second sprocket 32; the first sprocket 31 and the second sprocket 32 ​​are connected to the support frame 5 via sprocket bearings; the first sprocket 31 and the second sprocket 32 ​​are connected via the pushing chain 33; the driving device is also used to drive the first sprocket 31 to rotate; the pushing frame 2 is disposed on the pushing chain 33. After the driving device is started, the first sprocket 31, in conjunction with the second sprocket 32, drives the pushing chain 33 to move cyclically on the support frame 5. This causes the pushing frame 2 to move cyclically on the support frame 5. The first sprocket 31 is located at the inlet end of the scalding tank 1, and the second sprocket 32 ​​is located at the outlet end of the scalding tank 1; when the pushing frame 2 moves into the interior of the scalding tank 1, part of the pushing frame 2 is submerged in the hot water, and moves from the inlet end to the outlet end under the drive of the pushing chain. After the pig enters the scalding tank 1, it slides down the slope between the two pushing frames 2. The pusher 2 propels the pig forward along a predetermined path within the scalding tank 1 until the scalding process is complete. The entire process achieves automatic and continuous movement of the pig within the scalding tank 1. Because the speed of the pusher 2 is constant, the pig's residence time in the scalding tank 1 is consistent, resulting in a consistent scalding effect. Simultaneously, this device significantly improves the production efficiency of scalding and hair removal, reduces manual intervention, and lowers labor intensity.

[0028] In one possible embodiment, the pusher 2 includes a frame and mounting rods 23; the frame includes a frame 21 and multiple connecting rods 22 disposed within the frame 21; the frame 21 is connected to the mounting rods 23; the mounting rods 23 are connected to the pusher chain 33. The design of the frame 21 and connecting rods 22 reduces the resistance of the pusher 2 moving in hot water.

[0029] Preferably, the pusher frame 2 is further provided with a buffer 24; the buffer 24 includes a connecting part 242; the connecting part 242 is connected to two support legs 241 on both sides, forming a U-shaped structure; the bottoms of the support legs 241 are close to each other; the bottoms of the support legs 241 are connected to the frame 21. During the process of pushing the pig in the scalding tank 1, the buffer 24 can play a buffering role, reducing the force between the pusher frame 2 and the pusher chain 33, and avoiding damage to the pusher frame 2. The buffer 24, together with the swing mechanism 4 and the pusher mechanism 3, can turn the pig to a certain extent, making its scalding more even.

[0030] Preferably, the swing mechanism 4 further includes a push shaft and two push components; the push shaft includes a first push shaft 341 and a second push shaft 342, which are respectively connected to the support frame 5 via sprocket bearings; the first push shaft 341 is connected to the first sprockets 31 of the two push components at both ends; the second push shaft 342 is connected to the second sprockets 32 of the two push components at both ends; the swing mechanism 4 further includes a transmission component; the reducer further includes a first output shaft; the first output shaft drives the first push shaft 341 to rotate via the transmission component, thereby driving the first sprockets 31 at both ends of the first push shaft 341 to rotate, thus enabling the two push components to move synchronously in a cyclic manner. Each push frame 2 is connected to the push chain 33 of the two push components, so that the force on the push frame 2 is more balanced during the movement. Optionally, the push chain 33 includes multiple mounting links; each mounting link includes a mounting side plate; the mounting rod 23 is connected to the mounting side plate 331; the mounting links are evenly distributed on the push chain 33.

[0031] Optionally, the transmission assembly includes a driving wheel 38, a driven wheel 35, and a drive chain; the driving wheel 38 is mounted on the first output shaft; the driven wheel 35 is mounted on the first push shaft 341; the driving wheel 38 and the driven wheel 35 are sprockets driven by a drive chain. Optionally, the transmission assembly includes a driving wheel 38 and a driven wheel 35, both of which are gears that mesh with each other for transmission. Optionally, the driving wheel 38 and the driven wheel 35 are pulleys driven by a belt or synchronous belt.

[0032] Preferably, the transmission assembly further includes an adjustment component; the adjustment component includes an adjustment seat 361, on which a tensioning wheel 362 is provided; the adjustment seat 361 is also provided with two fixing grooves 363; the fixing grooves 363 are strip-shaped; the support frame 5 is also provided with mounting holes corresponding to the fixing grooves 363; the mounting holes and fixing grooves 363 are connected by mounting bolts; the tensioning wheel 362 cooperates with the drive chain. The strip-shaped fixing grooves 363 can adjust the position of the seat 361 on the support frame 5, change the positional relationship between the tensioning wheel 362 and the drive chain, thereby making the drive chain in a tensioned or slack state, which is convenient for replacement.

[0033] Preferably, both the first sprocket 31 and the second sprocket 32 ​​are connected to the support frame 5 via a tensioning assembly 37. The tensioning assembly 37 includes an upper slide rail 371, a lower slide rail 372, a slider seat 374, and an adjusting screw 373. The upper slide rail 371 and the lower slide rail 372 are fixedly connected to the support frame 5. The upper slide rail 371 and the lower slide rail 372 are provided with raised slide tracks opposite each other. The slider seat 374 is provided with a concave slide groove that mates with the slide track. The outer ring of the sprocket bearing is connected to the slider. The inner ring of the sprocket bearing is connected to the push shaft. The support frame 5 is provided with a threaded hole. The adjusting screw 373 mates with the threaded hole. The top of the adjusting screw 373 abuts against the slider seat 374. In use, the slider seat 374 is placed between the upper slide rail 371 and the lower slide rail 372, with the slide track and slide groove mate. The adjusting screw 373 is located inside the push chain 33. When adjusting the adjusting screw 373, its top abuts against the slider seat 374, thus fixing the position of the slider seat 374 in conjunction with the push chain 33. During maintenance, adjusting the adjusting screw 373 away from the slider seat 374 allows the push chain 33 to change from a tensioned state to a slack state, facilitating replacement of the push chain 33. Proper tension adjustment can reduce wear between the chain and sprocket, extend the service life of the equipment, and reduce the failure rate. Preferably, the tensioning assembly 37 also includes a positioning plate 375, which connects the upper slide rail 371 and the lower slide rail 372. The positioning plate 375 has a positioning hole; the adjusting screw 373 passes through the positioning hole and abuts against the slider seat 374. The positioning hole can fix the force direction of the adjusting screw 373, better securing the slider seat 374.

[0034] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
