As described above, the two surfaces (bottom surface and top surface) having the largest area of the quick-frozen raw tallow packing bag are disposed vertically on the feeding device 1, and thus, as shown in fig. 1, after entering the hole poking mechanism 3 from the feeding device 1, the two surfaces poked by the hole poking structure are the two surfaces having the largest area, which can be understood as the two largest rectangular surfaces among the projection surfaces in the form of rectangular parallelepiped.

Further, two-way lead screws 34 at the two ends of the first clamping plate 31 and the second clamping plate 32 are fixedly connected with a gear 35 at the same side, and the two gears 35 are in transmission connection through a toothed belt, so that the two-way lead screws 34 are driven by a motor to synchronously rotate, and the movement that the first clamping plate 31 and the second clamping plate 32 face to each other or depart from each other is realized. Through the arrangement, when the quick-frozen raw tallow packaging bag enters the hole poking mechanism 3, the two-way screw rod 34 can be rotated to clamp the quick-frozen raw tallow packaging bag, and then the hole poking is carried out.

Optionally, the first clamping plate 31 and the second clamping plate 32 are further provided with baffle structures at two ends in a sliding manner, so that the two bidirectional screw rods 34 are separated from the quick-frozen raw beef tallow packing bag entering the middle part.

It should be noted that the pressure plate 363 is provided to control the depth of the penetration when the hole is pierced, so as to avoid the penetration depth being too shallow or too deep; the main purpose of puncturing the holes in the invention is to puncture the packaging bag, enough saline enters during salt moistening treatment, and in order to avoid generating fragments during puncturing the holes, a conical needle point 364 is adopted to puncture the holes, so the puncturing depth needs to be set to a reasonable value, only a small opening can be punctured if the depth is too shallow, only a small part of saline enters during subsequent salt moistening treatment, the ice breaking efficiency is influenced, and the puncturing depth can not be conveniently judged if the depth is too deep, so unnecessary work is caused. According to the invention, through the arrangement of the hole poking structure, when the quick-frozen raw tallow packing bag is clamped by the first clamping plate 31 and the second clamping plate 32, the hole poking is carried out, at the moment, the stroke of the piston of each hole poking structure is possibly different, because the quick-frozen raw tallow packing bag is not an ideal cuboid structure, the surface of the quick-frozen raw tallow packing bag can have certain unevenness or unevenness, but the depth of the hole poking is not influenced, when the dent exists, only the piston rod 362 of the corresponding hole poking structure needs to be further compressed, if the pressure reaches a certain value and cannot be further deepened, and the hole poking needle 36 does not reach the full stroke, the pressure plate 363 indicates that the pressure plate is tightly pressed on the surface of the quick-frozen raw tallow packing bag, and the hole poking reaches the preset depth, so that the arrangement of the pressure plate 363 can conveniently judge the hole poking condition.

It should be noted that the bottom plate 33 at the bottom of the hole poking mechanism 3 in this embodiment is further connected with a power telescopic mechanism (not shown in the figure), so that after the hole poking is finished, the bottom plate 33 can be slid away, so as to conveniently feed the quick-frozen raw beef tallow packaging bag with the hole poked finished into the top of the slope surface 45 of the slope surface cutting mechanism 4.

Further, as shown in fig. 1 and 5, the slope cutting mechanism 4 is obliquely disposed below the hole poking mechanism 3, and includes a slope 45 and spring cavities 41 symmetrically disposed on both sides of the slope 45, and along the oblique direction of the slope 45, the spring cavities 41 on both sides are symmetrically provided with a plurality of sliding rods 43 extending out of the spring cavities 41 and capable of sliding in the transverse direction of the slope 45, one end of the sliding rod 43 extending out of the spring cavity 41 is hinged to the elastic strip 42, the elastic strip 42 is disposed on the slope 45, the top end of the elastic strip is fixed to the slope 45, the bottom end of the elastic strip is provided with a cutter 46, in the upward and downward direction of the slope 45, the elastic strips 42 on both sides bend toward the middle of the slope 45, and the stroke of the sliding rods 43 gradually increases. By the arrangement, after the quick-frozen raw tallow packaging bags are fed into the slope cutting mechanism 4, in the process of sliding downwards, the elastic strips 42 can guide the quick-frozen raw tallow packaging bags, and cutting edges on two sides of the quick-frozen raw tallow packaging bags with different sizes can be utilized by the cutting knife 46, so that subsequent film tearing is facilitated. Utilize cutting knife 46 cooperation to give birth to the motion of tallow wrapping bag on the assembly line and carry out the notch, this kind of mode compares in traditional rotatory cutting mode, more can avoid the production of plastics piece, ensures food safety.

Preferably, a remaining section 47 is further arranged at the bottom of the slope 45, which is only an inclined plane, and no other mechanism is arranged, and the dimension of the remaining section 47 in the up-down direction of the slope 45 is greater than the dimension of the quick-frozen raw tallow packing bag in the corresponding direction, so that the cutting knife 46 can ensure that a complete cut is formed on the side edge of the quick-frozen raw tallow packing bag. The slope surface notch cutting mechanism 4 slides along the slope surface 45 by the self weight of the quick-frozen raw beef tallow packaging bag and the raw beef tallow therein to complete cutting, so that the slope surface is set to have a large inclination angle, and the preferable inclination angle is greater than 60 degrees.

Further, set up at domatic cutting mechanism 4's downstream side level cutting mechanism 5, level cutting mechanism 5 includes baffle 51, push pedal mechanism 52 and horizontal cutting knife mechanism 53, and wherein, baffle 51 corresponds with domatic cutting mechanism 4's downside export, prevents that the tallow wrapping bag is being got into in the quick-freeze dashes out during level cutting mechanism 5, and push pedal mechanism 52 is located one side of domatic cutting mechanism 4's downside export, is used for promoting the tallow wrapping bag is given birth to the quick-freeze removes to horizontal cutting knife mechanism 53 to in the conveying pond of conveying pond mechanism 6 with its final propelling movement. Specifically, the push plate mechanism 52 includes a fixed plate 521, a thrust screw 522 is slidably disposed in the middle of the fixed plate 521, and a push plate 523 is disposed on a side of the thrust screw 522 facing the conveying pool mechanism 6.

The horizontal cutter mechanism 53 is arranged in a manner similar to the elastic strip 42, the cutter 46 and the like on the slope cutting mechanism 4, and will not be described herein again.

The transfer pool mechanism 6 of the present invention includes a first transfer belt 61, a brine 62, a second transfer belt 63, and a third transfer belt 64 disposed in the transfer pool, wherein the first transfer belt 61 and the second transfer belt 63 are both disposed horizontally, the first transfer belt 61 is completely immersed in the brine 62, the second transfer belt 63 is partially immersed in the brine 62, and a transfer passage for the quick-frozen raw beef tallow packing bags to pass through is formed between the first transfer belt 61 and the second transfer belt 63. It is further noted that the saline water is edible saline water, namely sodium chloride saline water; the arrangement of the first conveyor belt 61 mainly serves three purposes: first, the first conveyor belt 61 is immersed in the brine 62, and when the conveying rotation is performed, the first conveyor belt can drive the surrounding fluid to flow, so that the water temperature in the whole conveying pool is promoted to be balanced, which is favorable for the conveying pool with longer length; secondly, because the invention aims at the industrial production and processing, the distance between the first conveyor belt 61 and the second conveyor belt 63 is preset during the arrangement, so that for most quick-frozen raw beef tallow packaging bags with the same shape and size, when the quick-frozen raw beef tallow packaging bags are conveyed in the conveying channel, the clearance between the top surface and the bottom surface of the quick-frozen raw beef tallow packaging bags and the two

conveyor belts

61 and 63 can be small or even zero, and therefore, saline water can easily enter the position between the plastic bag and the raw beef tallow due to certain extrusion action to promote the unfreezing; and thirdly, the double conveying belts convey the raw beef tallow, so that the conveying capacity is stronger, a large number of quick-frozen raw beef tallow packaging bags can be conveyed simultaneously, and the processing capacity is improved.

Further, when the second conveying belt 63 is arranged, the second conveying belt 63 is arranged on the water surface, the circle center of the corresponding belt wheel is located above the water surface, and the second conveying belt 63 at the bottom of the belt wheel is located below the water surface. It should be noted that the brine 62 adopted in the salt moistening treatment of the present invention is high-concentration brine, so that raw tallow generally suspends on the water surface, and at this time, the raw tallow can be brought into the water by the friction force of the second conveyor belt 63, but the rotation speed of the second conveyor belt 63 required by this scheme is high, which results in that the quick-frozen raw tallow packaging bag to be subjected to the salt moistening treatment is rapidly conveyed to the conveying tank, or the conveying tank needs to be lengthened to meet the requirement of the salt moistening treatment time, which is disadvantageous for the stability of the system; therefore, in order to better achieve the object of the present invention, a rotating wheel (not shown) may be separately provided in front of the second conveyor belt 63, so that the quick-frozen raw beef tallow packing bags to be salt-wet are rotated at a high speed by the rotating wheel to be rotated below the water surface and then enter below the second conveyor belt 63, and the second conveyor belt 63 may be maintained at a relatively low conveying speed (compared to the linear speed of the rotating wheel). It should be further noted that the high-concentration brine mentioned herein is brine with a salt content of 10% to 20% (preferably 15% brine, which is convenient for preparation and subsequent concentration control), and the brine concentration used in thawing of common meat products is below 10% in order to avoid cell destruction thereof, so as to maintain the taste of the meat product.

Further, a third conveyor 64 is disposed obliquely, and is used for conveying the quick-frozen raw beef tallow packaging bag subjected to salt moistening treatment through the conveying passage to other parts of the conveying pool mechanism 6 which are separated from the salt water 62 at the upper part of the conveying pool, for example, to a fourth conveyor 65 which is disposed horizontally, and carrying out subsequent film tearing treatment.

As an example, fig. 8 shows a schematic diagram of a subsequent tearing process (in the drawing, the wide arrow indicates the moving direction of the quick-frozen raw tallow packaging bag), a first tearing wheel 66 is arranged immediately behind the fourth conveyor 65, a second tearing wheel 67 is arranged right above the first tearing wheel 66, the first tearing wheel 66 and the second tearing wheel 67 are both provided with tearing bulges, the size of the tearing bulges is slightly smaller than the maximum diameter of the needle point 364, namely, the tearing bulges can be just poked into the holes poked by the needle point 364, it is anticipated that, in order to meet the moving direction indicated by the wide arrow in the drawing, the first tearing wheel 66 rotates clockwise, the second tearing wheel 67 rotates counterclockwise, the raw tallow surface in the quick-frozen raw tallow packaging bag after salt moistening treatment is softened, the packaging bag and the raw tallow are unfrozen and do not stick (or the sticking is obviously reduced), and since the front, back, left and right sides of the packaging bag are cut, when the quick-frozen raw tallow is conveyed onto the first tearing wheel 66, the first tearing wheel 66 and the second tearing wheel 67 are capable of further detecting the packaging bag and the packaging bag is further pushed into the packaging bag along the horizontal direction, and the packaging bag is easily detected, the next step of the quick-frozen raw tallow packaging bag, and the packaging bag is conveyed along the horizontal direction, and the tearing bulges, and the packaging bag is further processed into the packaging bag, and the packaging bag is easily detected; the packaging bags torn off by the first film tearing wheel 66 can be scraped off from the first film tearing wheel 66 through the matching of the barrier strip 70, and then fall downwards or enter other conveying equipment; the packages torn off by the second film tearing wheel 67 can be conveyed out by the film suction wheel 68. The suction film wheel 68 can be implemented using a conventional rotary wheel coupled with a vacuum pump, which is not a major problem to be solved by the present invention and will not be described in detail herein. In addition, it should be noted that, in order to ensure that the first film tearing wheel 66 and the second film tearing wheel 67 perform the synchronous film tearing process, the rotating shaft of the first film tearing wheel 66 is stationary in the vertical direction, that is, only rotates around the circle center of the first film tearing wheel 66, while the rotating shaft of the second film tearing wheel 67 not only rotates, but also can perform compensation adjustment in the vertical direction, which can be achieved by providing a thrust mechanism, such as a spring, on the rotating shaft of the second film tearing wheel 67, which is mature in the prior art and will not be described in detail herein.

It is further noted that the use of high concentrations of saline increases the thawing rate; because the plastic is easy to decompose toxic substances at high temperature, the invention can adopt warm water with normal temperature or the temperature lower than 50 ℃ to carry out salt moistening treatment, namely, the plastic can be quickly thawed. Meanwhile, the adopted cutting knife 46 is matched with the movement of the raw beef tallow packaging bag on the production line to cut the opening, so that plastic scraps can not be formed, and the food safety is ensured.
