Description

Peeling machine

Technical Field

The invention provides a decorticator, in particular to a decorticator for slaughtering field.

Background

In slaughtering pigs, cattle, sheep, poultry, fish and the like, it is often necessary to peel the carcass of an animal. When peeling an animal carcass, it is most common for a worker to peel the carcass manually using a cutter such as a peeling knife.

The traditional manual peeling operation is laborious and time-consuming, and has very low operation efficiency. Even a skilled worker often takes several tens of minutes to complete, for example, the skinning operation of a pig carcass.

In addition, such conventional manual peeling operations place high demands on the skill level of the worker performing the peeling operation. If the skill level of the worker performing the peeling operation is not high enough or negligence occurs during the operation, subcutaneous meat is easily damaged, resulting in uneven quality of the meat after peeling and trimming. In particular, for meat products that are relatively expensive, such conventional manual peeling operations can have significant adverse effects on meat yield and meat quality.

Problems to be solved by the invention

Aiming at the problems of low efficiency and easy adverse effect on meat quality in the prior art, the invention provides a peeling machine which can use a power source to drive a cutter to perform peeling operation, thereby being capable of rapidly performing peeling operation and avoiding damaging subcutaneous meat in the peeling operation process.

Solution for solving the problem

The invention provides a peeling machine, which comprises a cutting part and a driving part, wherein the cutting part is used for executing peeling operation, the driving part is used for driving the cutting part, the cutting part comprises a tooth roller and a cutting knife, the tooth roller is used for biting skin tissues of a carcass when the peeling operation is executed, and the tooth roller rotates around a roller shaft line of the tooth roller under the driving of the driving part; the cutter blade is located on a downstream side of a position where the spur roller is in contact with the skin tissue in a rotational direction of the spur roller.

The toothed roller in the cutting part can bite the skin tissue of the carcass, and the toothed roller is driven by the driving part, so that the toothed roller can send the bitten skin tissue to a downstream cutting knife for cutting when rotating. Thus, labor can be saved in the peeling operation, and the peeling operation efficiency is remarkably improved. The cutter is only used to separate skin tissue gripped by the toothed roller from the carcass and does not cut into the subcutaneous meat. In addition, the cutting depth of skin tissues can be always ensured to be within the range of the maximum cutting depth of the cutting part by utilizing the shape and the size of the tooth roller and the distance between the tooth roller and the cutting knife, so that a worker can ensure that subcutaneous meat is not damaged in the peeling operation process by only selecting proper knife specifications when working.

Preferably, the driving part includes a pneumatic motor.

The pneumatic motor adopts compressed air as the only power source, and does not need to use electric power, so that electric shock injury to workers can be avoided.

The peeling machine of the embodiment has compact appearance and light weight, and is convenient for handheld operation. For example, the peeler of the present embodiment may have an overall dimension of about 230mm in length, about 115mm in width, and about 65mm in height, with a total weight of about 1.81kg.

As shown in fig. 1, the cutter section includes a spur roller housing 104, a spur roller section accommodated in the spur roller housing 104, and a cutter 110. In the assembled state, the cutting edge of the cutter 110 is located at the cutting operation position in the present embodiment. The tooth roller portion includes a tooth roller shaft 114, a left tooth roller 106, a right tooth roller 113, and a worm wheel shaft 105. Both ends of the spur roller shaft 114 are respectively inserted into mounting holes formed in the spur roller housing 104. The axial center portion of the worm wheel shaft 105 is provided with a through hole for engagement with the pinion shaft 114, and in the assembled state, the worm wheel shaft 105 can rotate around the pinion shaft 114.

The center portion of the worm wheel shaft 105 is provided with a worm wheel for mating connection with the driving portion shown in fig. 2. The toothed roller shell 104 is connected with a fastening screw 115 for providing a fastening force to the fit between the worm wheel on the worm wheel shaft 105 and the worm of the driving part in an assembled state, preventing the worm wheel and the worm from being separated.

The left and right end portions of the worm wheel shaft 105 are provided with shaft portions for mounting the left side spur roller 106 and the right side spur roller 113. The left tooth roller 106 is fitted over the left end shaft portion of the worm wheel shaft 105, and a left key 108 for transmitting power is provided between the left tooth roller 106 and the left end shaft portion of the worm wheel shaft 105. The right tooth roller 113 is fitted over the right end shaft portion of the worm wheel shaft 105, and a right key 112 for transmitting power is provided between the right tooth roller 113 and the right end shaft portion of the worm wheel shaft 105. A spacer 107 is provided on the outer side in the axial direction of the left and right spur rollers 106 and 113, and the spacer 107 is fitted over the spur roller shaft 114. As the worm wheel shaft 105 rotates, the left side tooth roller 106 and the right side tooth roller 113 rotate together with the worm wheel shaft 105.

A plurality of sets (five sets are illustrated in the figure) of toothed disks arrayed in the axial direction of the worm wheel shaft 105 are provided on the outer peripheral surfaces of the left-side toothed roller 106 and the right-side toothed roller 113. Each set of the toothed plates includes a plurality of biting teeth arranged in the circumferential direction of the toothed roller, and tooth tops of the biting teeth extend toward the downstream side in the rotational direction of the toothed roller shaft 114 with respect to tooth roots of the biting teeth. The biting teeth of this shape are capable of firmly biting skin tissue, preventing the skin tissue from being separated from the tooth roller before being cut. A space is provided between any two adjacent sets of toothed disks in the axial direction of the worm wheel shaft 105. In the present embodiment, a cutting width of about 82.5mm can be achieved with the left and right spur rollers 106 and 113.

The tooth comb 111 is a member for cleaning the left tooth roller 106 and the right tooth roller 113 at the time of peeling work, and the tooth comb 111 is provided with left and right two sets of teeth corresponding to the left tooth roller 106 and the right tooth roller 113, respectively. The teeth comb 111 is located on the downstream side of the cutting operation position in the rotational direction of the worm wheel shaft 105, and the positions of the teeth comb correspond to the intervals between the toothed disks so that the teeth comb can be inserted between the toothed disks to realize the cleaning function. In fig. 1, six teeth are included in each of the left and right sets of teeth in order to clean the left and right tooth rollers 106 and 113 having, for example, five sets of toothed plates.

A cutter 110 and a cutter rest 109 for supporting the cutter 110 are provided below the toothed roller portion. The cutter blade 110 is located downstream of the left and right spur rollers 106 and 113 in the rotational direction of the spur roller shaft 114. In the peeling operation, the cutter 110 is used to separate the skin tissue gripped by the toothed disc and fed to the cutting operation position from the carcass. The cut skin tissue is discharged in a long sheet form from the gap between the cutter blade 110 and the left and right toothed rollers 106 and 113, and the width of the cut skin tissue corresponds to the aforementioned cutting width. The cutter head 109 is fixed to the underside of the toothed roller shell 104 by two fastening screws 101. Removal of the cutting blade holder 109 exposes the toothed roller portion, thereby facilitating replacement of the toothed roller portion. In other words, the present embodiment has an advantage of easy replacement of the peeling cutter.

As shown in fig. 1, D-shaped notch portions are provided at positions corresponding to the fastening screw 101 at both ends of the toothed roller shaft 114, and in the assembled state, the screw portion of the fastening screw 101 presses the toothed roller shaft 114 at the D-shaped notch portions. The screw portion of the fastening screw 101 that is in contact with the D-shaped notch portion is not a single-diameter circular shape, but a shaped rod having different diameters in different directions in cross section. Thus, when the fastening screw 101 rotates, the D-shaped notch portion is pushed to different degrees, so that the tooth roller shaft 114 is driven to move away from or approach the cutting knife 110. Thus, the fastening screw 101 can simultaneously fix the cutter 110 and adjust the distance between the cutter 110 and the left and right toothed rollers 106 and 113.

A spur roller cover 103 is provided on the front surface of the spur roller housing 104, and the spur roller cover 103 is fixed to the spur roller housing 104 by a screw 102. The spur roller cover 103 is located upstream of the cutting operation position in the left spur roller 106 and the right spur roller 113 in the rotational direction of the worm wheel shaft 105. In other words, the portion for peeling work (i.e., the portion that engages with the skin tissue) of the left and right spur rollers 106 and 113 is located between the spur roller cover 103 and the cutter 110.

The external dimensions of the toothed discs in the left 106 and right 113 toothed rolls and the distance between the cutter 110 and the left 106 and right 113 toothed rolls determine the maximum depth of cut into the carcass when the peeling operation is performed. During the peeling operation, the toothed disc and cutter 110 cooperate to remove only skin tissue within the maximum depth of cut without damaging the meat at a deeper location. The cutter having the appropriate maximum cutting depth (the left side toothed roller 106, the right side toothed roller 113, and the cutter 110 in this embodiment) can be selected according to the characteristics of the carcass. For example, a maximum cut depth of 1.5mm, 3mm, or 5mm may be selected (but is not limited thereto). Therefore, when pigs, cattle, sheep, poultry, fish and the like are slaughtered, the skinning operation can be performed by simply selecting proper cutter specifications, and the manual operation difficulty is greatly reduced.

The gear teeth on the inner peripheral side of the planetary ring gear 227 mesh with the gear teeth of the intermediate gear 228, so that the rotation of the planetary ring gear 227 can be transmitted to the planetary hub assembly 230 while achieving deceleration by utilizing the gear engagement relationship between the planetary ring gear 227 and the intermediate gear 228.

The planetary hub assembly 230 has a shaft portion protruding from the front end of the reduction gear housing 231, on which a bearing 232, a spacer 233, a bearing 232, a wave spring 234, an oil seal 235, a bearing cap 236, a ring 237, and a worm 238 are provided in this order from the rear to the front. The worm 238 is in driving connection with the worm gear in the worm wheel shaft 105.

The air valve means provided at the rear end of the motor housing 224 includes a valve housing assembly 216, a quick connector 217, a muffler 218, an O-ring 215, a valve plunger 214, a compression spring 213, an O-ring 212, an air valve plug 211, a trigger lever 220, and a positioning pin 219. The valve housing assembly 216 is connected to the rear end of the motor housing 224 with a sealing gasket 222 and an O-ring 221 disposed between the valve housing assembly 216 and the motor housing 224.

A quick connect head 217 and muffler 218 are disposed behind the valve housing assembly 216. The quick connector 217 is adapted to connect to an external pipe for delivering compressed air. Muffler 218 is used to eliminate noise generated when compressed air is introduced.

The valve plunger 214 is inserted into the valve housing assembly 216 from the upper side in the drawing for controlling the opening and closing of the air valve device. An O-ring 215, a compression spring 213, an O-ring 212, and an air valve plug 211 are provided on the valve plunger 214. The trigger lever 220 is positioned by a dowel pin 219 on the valve housing assembly 216 in a position where it can pressurize the air valve plug 211.

The valve plunger 214 is movable between a first position in which the air valve device is turned on and a second position in which the air valve device is turned off. With the air valve plug 211 not depressed, the valve plunger 214 is held in one of the first position and the second position by the compression spring 213. When the air valve plug 211 is depressed, the valve plunger 214 is pressed to the other of the first position and the second position against the spring force of the compression spring 213. Thus, by depressing or releasing trigger lever 220, the position of valve plunger 214 can be controlled, thereby controlling the opening and closing of the air valve assembly.

Preferably, for safety reasons, the position of the valve plunger 214 when the air valve plug 211 is not depressed is set to the second position in which the air valve device is turned off, and the position of the valve plunger 214 when the air valve plug 211 is depressed is set to the first position in which the air valve device is turned on. Thus, the knife will only have a cutting action when the worker intentionally depresses trigger lever 220. If the worker holds the peeler loose, the supply of compressed air can be cut off at the first time when the peeler falls off from the hand, and the like, so that accidental injury of a cutter is avoided.

A grip portion 223 is further provided in the handle portion, and the grip portion 223 may be designed to be freely rotatable or fixed with respect to the handle portion. The front and rear ends of the handle portion 223 are shown as annular engaging portions, respectively, which may be fitted over a housing (not shown) of the handle portion. When it is desired that the grip portion 223 be fixable relative to the handle portion, a pawl may be provided at the rear end tail of the grip portion 223 as shown. The grip portion 223 is fixed relative to the handle portion, for example by clamping a jaw to the quick coupler 217. As shown, the quick connector 217 and the air valve plug 211 are positioned in opposite circumferential positions with respect to each other with respect to the center of the handle portion, so that the fixed handle portion 223 is positioned just above the air valve plug 211 and the trigger lever 220, thereby preventing the air valve plug 211 and the trigger lever 220 from being erroneously triggered. When it is desired that the grip portion 223 can be freely rotated, for example, in a 360 degree range with respect to the handle portion, a grip portion without a claw can be used, in which case a worker can flexibly adjust the posture while holding the grip portion so as to obtain a comfortable holding position.

The decorticator of the present invention can save manpower, does not require high decortication skill of workers, and can greatly increase the decortication speed, for example, the decortication of a pig carcass can be completed within one minute, thus the decorticator is especially suitable for use in large slaughterhouses, etc. In addition, the peeling machine is particularly suitable for peeling operation under the condition of high requirements on meat quality because the meat under the skin is not damaged.

While the invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be readily understood by those skilled in the art that various modifications and equivalents may be made thereto without departing from the spirit and scope of the invention as defined in the appended claims.
