Abstract
Description
Technical Field
[0001] This utility model relates to the field of livestock slaughtering and processing machinery and technology, specifically to a conveyor chain assembly for a pig hair removal device. Background Technology
[0002] After slaughter, livestock need to undergo dehairing. The current scalding and dehairing process involves immersing the animal carcass in hot water in a scalding tank for a certain period of time before sending it to a dehairing machine. This scalding process requires manual removal of the carcass material from the scalding tank after it has been determined to be properly scalded and transferring it to the dehairing machine. This not only makes it difficult to standardize the scalding time for each individual piece of material, but also makes it easy for errors to be recorded or misjudged, resulting in the material being under-scalded or over-scalded when it is taken out of the scalding tank and transferred to the dehairing machine. This directly affects the processing quality of the entire scalding and dehairing process. Utility Model Content
[0003] The technical problem this utility model aims to solve is to overcome the shortcomings of existing scalding processes, such as the difficulty in standardizing the scalding time of each individual carcass and the large number of under-scalded or over-scalded items caused by errors in manual judgment. This invention provides a conveyor chain assembly for pig hair removal equipment, which is easily matched and installed in existing scalding tanks, forming a chain-like unidirectional conveying structure. By controlling the conveying speed, the scalding time of each individual carcass is standardized, ensuring the scalding effect. The lever structure allows for orderly conveying of materials one by one, facilitating judgment of the transfer order downstream and eliminating errors in recording and judgment. This ensures the hair removal effect of the subsequent hair removal machine, thereby improving the processing quality of the entire scalding and hair removal process.
[0004] The conveyor chain assembly of this pig hair removal equipment includes a lever mechanism for conveying materials, a mounting belt for fixing the lever mechanism, a transmission chain for driving the mounting belt, a sprocket mechanism for driving the transmission chain, and a chain track for limiting the trajectory of the transmission chain by fixing it to the side walls of the scalding tank. The mounting belt and the transmission chain are both embedded in the chain track, and the two ends of the transmission chain are engaged with the sprocket mechanism for driving its operation. The mounting belt is wound around the transmission chain. The lever mechanism includes several lever frames fixed to the mounting belt and several levers fixed at equal intervals to each lever frame.
[0005] Furthermore, the lever frame is provided with several lever seats, and the lever is detachably mounted on the corresponding lever seat by a pair of bolts.
[0006] Furthermore, the mounting belt is tensioned and fixed to the transmission chain on both sides or connected and fixed to the transmission chain.
[0007] Furthermore, the sprocket mechanism includes a driving sprocket shaft and a driven sprocket shaft. At each end of the drive chain of the driving sprocket shaft and the driven sprocket shaft, a pair of sprockets that mesh with the drive chain are fixed. The driving sprocket shaft is equipped with a drive motor for rotating the drive unit.
[0008] Furthermore, the chain track includes an inner support frame and an outer shielding frame, wherein the inner support frame is provided with a support frame inside and welded square steel is provided on both sides of the inner support frame.
[0009] This utility model relates to a conveyor chain assembly for a pig hair removal device. It overcomes the shortcomings of existing scalding processes, such as the difficulty in standardizing the scalding time for each individual carcass, and the large number of under-scalded or over-scalded items caused by errors in manual judgment. Its beneficial effects are as follows:

[0025] The present invention will be further described below with specific embodiments, but the scope of protection of the present invention is not limited to the following embodiments.
[0026] Implementation method 1: such as Figures 1 to 5 As shown, the conveyor chain assembly of this pig hair removal equipment includes a lever mechanism 1 for conveying materials, a mounting belt 2 for fixing the lever mechanism 1, a transmission chain 3 for driving the mounting belt 2, a sprocket mechanism 4 for driving the transmission chain 3, and a chain track 5 fixed to the side walls of the scalding tank to limit the trajectory of the transmission chain 3. The mounting belt 2 and the transmission chain 3 are both embedded in the chain track 5, and the two ends of the transmission chain 3 are engaged with the sprocket mechanism 4 for driving its operation. The mounting belt 2 is wound around the transmission chain 3. The lever mechanism 1 includes several lever frames 11 fixed to the mounting belt 2 and several levers 12 fixed at equal intervals on each lever frame 11. The drive mechanism drives the chain forward, the chain transmits to the belt, and drives the levers. The material is propelled from the upstream inlet area on the right to the downstream outlet area on the left by the levers moving downwards. The scalding time is limited by the conveying speed, and the single piece of material is determined by unidirectional conveying.
[0027] Implementation method 2: such as Figure 4As shown, the conveyor chain assembly of this pig hair removal equipment has several lever seats 13 on the lever frame 11. The levers 12 are detachably mounted on the corresponding lever seats 13 by a pair of bolts 131. This allows for adjustment of the lever length according to the size of the material, ensuring that one carcass is intercepted and pushed between each row of levers, thereby ensuring the soaking time of each material unit and the downstream discharge rate.
[0028] Implementation method 3: such as Figure 2 As shown, the conveyor chain assembly of this pig hair removal equipment has the mounting belt 2 tensioned and fixed on both sides to the transmission chain 3, or connected and fixed to the transmission chain 3. The tensioning and fixing method facilitates belt disassembly and provides derailment buffer protection in case of machine jamming; the fixed connection can improve the accuracy of conveying time and conveying force.
[0029] Implementation method 4: such as Figure 3 , 5 As shown, the sprocket mechanism 4 of the conveyor chain assembly of this pig hair removal equipment includes a drive shaft 41 and a driven shaft 42. A pair of sprockets 43 are fixed at each end of the transmission chain 3, meshing with the chain 3. The drive shaft 41 is equipped with a drive motor 44 for rotating the drive unit. The sprocket notches achieve meshing transmission by engaging with the connecting pins protruding from the side of the chain.
[0030] Implementation method 5: such as Figure 3 , 5 As shown, the chain track 5 of the conveyor chain assembly of this pig hair removal equipment includes an inner support frame 51 and an outer shielding frame 52. The inner support frame 51 has a support frame 53 inside and welded square steel bars 54 on both sides. The inner support frame supports the chain, belt, and lever frame, while the outer shielding frame prevents the chain from loosening. The two together form the running track of the chain. The support frame supports the two inner side frames to maintain the shape of the track. The welded square steel bars are used to weld to the inner wall of the scalding tank to achieve the overall installation and positioning of the assembly.
[0031] This pig hair removal equipment's conveyor chain assembly overcomes the shortcomings of existing scalding processes, such as the difficulty in standardizing the scalding time for each individual carcass and the large number of under-scalded or over-scalded items due to errors in manual judgment. It is easily installed within existing scalding tanks, forming a chain-like unidirectional conveyor structure. By controlling the conveying speed, standardized control of the scalding time for each carcass is achieved, ensuring scalding effectiveness. The lever structure allows for orderly, sequential material transport, facilitating judgment of the transfer order downstream and eliminating errors in recording and judgment. This ensures the hair removal effect of subsequent hair removal machines and improves the overall processing quality of the scalding and hair removal process.
