Description

Technical Field

[0001] The present invention relates to the technical field of packaging and conveying, and in particular to a packaging and conveying device for meat product processing. Background Art

[0002] The packaging and conveying device for meat product processing is mainly used to convey the packaged products to designated processes (such as inspection, labeling, boxing, etc.). Due to the influence of the residual heat of the heat sealing process and the initial temperature of the products, the surface temperature of the packaged products is generally relatively high. For example, beef and mutton after being packaged by an automatic vacuum packaging machine, or meat paste products formed by heat sealing after filling (the temperature of the heat sealing process plus the temperature of the materials inside the filling container). Therefore, if there is a lack of efficient immediate cooling, the high-temperature packaging is likely to create favorable conditions for the reproduction of microorganisms during the conveying process, and is also likely to cause the softening of the heat-sealed mouth, thus affecting the product quality.

[0003] In the prior art, such as a highly efficient meat vacuum packaging machine proposed in the publication number CN221091530U, the packaging machine includes a main body frame. One side of the top of the main body frame is fixedly connected with a cooling box. Both sides of the middle of the cooling box are fixedly connected with cooling devices arranged at equal intervals. One side of the cooling device is fixedly connected with a cooling pipe. One side of the middle of the main body frame is fixedly connected with a collection box. Although this packaging machine cools and reduces the temperature of the packaging bag through the cooling pipe, its cooling effect is poor, the efficiency is low, and the cooling is uneven. Summary of the Invention

[0004] Aiming at the defects existing in the above-mentioned prior art, the present invention provides a packaging and conveying device for meat product processing to solve the problem that the packaging and conveying device lacks efficient immediate cooling and is likely to affect the product quality.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment 1

[0041] As Figures 1 to 10 shown, the embodiment of the present invention application provides a packaging and conveying device for meat product processing, including: a first conveying mechanism 1, a first spraying structure 2, a refrigeration structure 3, a second conveying mechanism 4 and a cleaning structure 5.

[0042] The first conveying mechanism 1 includes a conveying plate 11 and a housing 12 covering the upper part of the conveying plate 11. The conveying plate 11 is inclined from the upstream to the downstream. A recovery cavity 111 and a refrigeration cavity 112 are provided inside the conveying plate 11, and a plurality of drainage holes 113 communicating with the recovery cavity 111 are opened on the surface of the downstream end of the conveying plate 11.

[0043] The upstream feeding end of the second conveying mechanism 4 is docked with the downstream discharging end of the first conveying mechanism 1. The first spraying structure 2, the refrigeration structure 3 and the cleaning structure 5 are arranged in sequence according to the meat product packaging transmission direction. Specifically, the first spraying structure 2 is installed above the upstream of the conveying plate 11 for surface spraying treatment of the meat product packaging during conveying; the refrigeration structure 3 includes a air supply pipeline 31 communicating with the inside of the housing 12 for air cooling treatment of the sprayed packaging; the cleaning structure 5 is arranged on the second conveying mechanism 4 for wiping and cleaning the surface of the cooled packaging.

[0044] Optionally, the refrigeration chamber 112 is arranged outside the recovery chamber 111. A collection tank 13 is arranged below a plurality of drain holes 113. The collection tank 13 is connected and communicated with the refrigeration chamber 112 through a diversion pipe 14. A drain pipe 15 for discharging the recycled water to the outside for recycling is connected to the recovery chamber 111. The refrigeration chamber 112 is provided with a cooling medium inlet and a cooling medium outlet. During use, by connecting the cooling medium inlet to an external cooling system, the cooling system inputs a cooling liquid or gas into the refrigeration chamber 112, so as to cool the conveying plate 11 and the recovery chamber 111. When the temperature of the cooling medium rises, the cooling medium is discharged through the cooling medium outlet for recycling. By integrating the refrigeration chamber 112 in the conveying plate 11, the refrigeration chamber can reduce the temperature of the plate surface, and the plate surface temperature is uniform. On the one hand, it can ensure the refrigeration effect of the conveying plate during the whole conveying process, accelerate the cooling speed, and avoid overheating at the bottom of the package. On the other hand, the water with an increased temperature after spraying is recovered to the recovery chamber 111, and the water in the recovery chamber 111 will be pre-cooled by the refrigeration chamber 112 on the outside, so as to accelerate the recycling and cooling efficiency of the recovered water.

[0045] Optionally, the first conveying mechanism 1 further includes baffles 16 arranged on both sides of the upper surface of the conveying plate 11, and support legs 17 arranged at the bottom of the conveying plate 11.

[0046] Optionally, both sides of the bottom end of the housing 12 are connected to the corresponding baffles 16. The left input end and the right output end of the housing 12 can be fully open structures or semi-open structures. The semi-open structure can reduce the loss of the cooling medium. The two ends shown in the figure are fully open structures.

[0047] During use, the package to be cooled enters from the upstream of the conveying plate 11. First, the first spraying structure 2 sprays cooling water to wash and cool the package. The water flow flows along the conveying plate 11 and enters the recovery chamber 111 through the drain holes 113. The sprayed package then enters the housing 12. The air flow conveyed into the housing 12 by the refrigeration structure 3 can further cool the package. Then the package enters the second conveying mechanism 4. During the conveying process of the second conveying mechanism 4, the cleaning structure 5 can not only dry the package to ensure that there is no water residue on the package, but also clean the stains or sundries attached to the surface of the package, so as to ensure the cleanliness of the package and improve the quality of the product. In practical applications, spraying and air cooling can also be selectively used according to needs. For example, when synchronous cleaning of the package is required, only the first spraying structure 2 can be selected.

[0048] In one embodiment, the first conveying mechanism 1 of the present invention can be assembled below a vacuum packaging machine or a storage tank, that is: the vacuum packaging machine or the storage tank is located above the upstream feeding end of the conveying plate 11, and the product can enter the conveying plate 11 after being packaged.

[0049] In one embodiment, after meat products are packaged by a vacuum packaging machine or minced meat products are bagged and sealed in a material tank, they can be transported to the conveyor plate 11 by a loading mechanism 6. The downstream discharge end of the loading mechanism 6 is connected to the upstream feed end of the conveyor plate 11. During use, the product can be pushed onto the conveyor plate 11 by a pushing mechanism. That is, the vacuum packaging machine or material tank is located above the loading mechanism 6. After the product is packaged, it is placed on the loading mechanism 6, and then the pushing mechanism pushes the product onto the conveyor plate 11. Of course, the loading mechanism 6 can also be a conveyor belt conveyor mechanism, a conveyor roller conveyor mechanism, etc., using the loading mechanism 6 to transport products that need to be cooled and cleaned. Those skilled in the art can configure it according to actual needs.

[0050] In one embodiment, the conveyor plate 11 can be directly constructed as a plate (slide plate). Due to the provision of the first spray structure 2, the clean water sprayed therefrom can enhance the lubrication of the conveyor plate. In another embodiment, a conveyor belt can be provided on the conveyor plate 11. The conveyor belt has filter holes formed therein to facilitate the flow of the sprayed liquid through the drainage holes 113 into the recovery chamber 111. Conveyor rollers are disposed around the periphery of the conveyor plate 11 and driven by drive rollers. The conveyor belt and its drive method are relatively mature existing technologies and are therefore not further described.

[0051] In one embodiment, the first spray structure 2 includes a mounting plate 21, a first spray pipe 22, and a plurality of first spray heads 23. The mounting plate 21 is connected to the baffle 16 on the first conveying mechanism 1 to be mounted above the conveying plate 11. The first spray pipe 22 is mounted on top of the mounting plate 21. The first spray pipe 22 has several branches evenly distributed along its length and connected to the first spray pipe 22. Each branch is equipped with a plurality of first spray heads 23. During operation, an external cooling water source is connected to the first spray pipe 22, and a water pump draws cooling water into the first spray pipe 22 before spraying it through the first spray heads 23.

[0052] Optionally, the first nozzle 23 is an atomizing nozzle. The water mist sprayed by the first nozzle 23 can simultaneously cool down and clean the package.

[0053] Optionally, the mounting plate 21 is adjustable. For example, both sides of the mounting plate 21 are slidably connected to the baffle 16 and secured with fixing bolts when slid to a designated position. During use, the mounting plate 21 can flatten the packages to prevent them from stacking. The adjustable mounting plate 21 facilitates matching packages of different heights and also facilitates height adjustment of the first nozzle 23.

[0054] In one embodiment, the refrigeration structure 3 includes a plurality of air supply ducts 31. The air inlet of the air supply duct 31 is connected to an existing air supply system, and the air supply system conveys a cooling air flow to the plurality of air supply ducts 31. The air outlet of the air supply duct 31 penetrates through the housing 12 and extends above the conveying plate 11. By extending the air supply duct 31 above the conveying plate 11, it is beneficial to improve the cooling effect.

[0055] In one embodiment, a turning mechanism 41 is provided on the second conveying mechanism 4, and a set of cleaning structures 5 are respectively arranged on both sides of the turning mechanism 41. The turning mechanism 41 is used to turn over the package. When the surface of the package is wiped and cleaned by a set of cleaning structures 5, the turning mechanism 41 turns over the package, and then the other set of cleaning structures 5 wipes and cleans the other side of the package. As an implementation scenario, by way of example. The second conveying mechanism 4 adopts a conveying roller conveying mechanism, the turning mechanism 41 adopts a turning drive roller, a servo motor for driving the turning drive roller to rotate in the opposite direction to the inner conveying roller of the second conveying mechanism 4 is installed on the outer wall of the second conveying mechanism 4, and both ends of the turning drive roller are rotationally connected to the inner wall of the frame of the second conveying mechanism 4 through bearings. The servo motor drives the turning drive roller to rotate in the opposite direction, so that the turning drive roller and the inner conveying roller of the second conveying mechanism 4 rotate in the opposite direction, so as to be able to turn over the package during the conveying process, so as to wipe and clean the back of the package. Anti-slip patterns can be provided on the outer wall of the turning drive roller to increase the friction for convenient turning. In other embodiments, the turning mechanism 41 can also adopt other existing technologies, such as a manipulator, etc.

[0056] Embodiment 2

[0057] The embodiment of the present invention application provides a packaging conveying device for meat product processing. On the basis of Embodiment 1, in this embodiment, a guiding structure 7 is further arranged between the first conveying mechanism 1 and the second conveying mechanism 4.

[0058] The guiding structure 7 includes a guiding plate 71 and a collection box 72. The guiding plate 71 is obliquely arranged between the first conveying mechanism 1 and the second conveying mechanism 4. A plurality of drainage grooves 710 are provided on the guiding plate 71, and the collection box 72 is arranged below the guiding plate 71, and a drainage hole is provided at its bottom. During use, the package output from the downstream of the conveying plate 11 is poured onto the second conveying mechanism 4 through the guiding plate 71. When the package passes through the guiding plate 71, the water attached to the package can flow into the collection box 72 through the drainage grooves 710, so that the water entering the second conveying mechanism can be reduced.

[0059] Optionally, one side of the housing 12 close to the guiding structure 7 extends towards the guiding structure 7, that is, the guiding structure 7 is covered in the housing 12. The collection box 72 is a top-open structure, and its upper end is connected to the lower end of the extended housing.

[0060] Optionally, there are multiple air supply ducts 31 in the refrigeration structure 3. Among them, at least one air supply duct 31 is provided above the corresponding position of the collection box 72. Of course, multiple air supply ducts 31 can also be arranged along the width direction of the housing 12 above the collection box 72, and the specific setting can be determined according to the width of the conveying plate 11. When the package passes through the guiding plate 71, most of the water on the package can be blown off through the air supply duct 31.

[0061] Embodiment 3

[0062] An embodiment of the present invention provides a packaging conveying device for meat product processing. On the basis of Embodiment 2, the guiding structure 7 further includes a driving cylinder 73 and a detection device 74.

[0063] In this embodiment, the driving cylinder 73 is installed in the collection box 72, and the detection device 74 is installed at the downstream discharge position of the conveying plate 11 for preliminary visual inspection of the packaged product. One end of the guiding plate 71 is hinged to the discharge end of the conveying plate 11, and the working end of the driving cylinder 73 is connected to the bottom of the other end of the guiding plate 71. The driving cylinder 73 can drive the guiding plate 71 to rotate around the hinged end, so that the end of the guiding plate 71 away from the hinged end faces the second conveying mechanism 4 or the collection box 72. That is, when the driving cylinder 73 does not act, the guiding plate 71 is in an initial inclined state and faces the second conveying mechanism 4 to guide the package onto the second conveying mechanism 4; when the driving cylinder 73 acts, the driving cylinder 73 drives the guiding plate 71 to rotate clockwise downward around the hinged end to an inclined state and faces the bottom of the collection box 72 to introduce the package into the collection box 72.

[0064] Furthermore, the detection device 74 is used to detect whether the package is qualified. Both the driving cylinder 73 and the detection device 74 are electrically connected to the controller. The controller receives the detection signal of the detection device 74 and judges whether the package is qualified. When it is qualified, the driving cylinder 73 does not act, that is, the package is introduced into the second conveying mechanism 4. When it is unqualified, the driving cylinder 73 is adjusted to act to introduce the unqualified package into the collection box 72.

[0065] The guiding plate 71 can be connected to the discharge end of the conveying plate 11 through a rotating shaft (not shown in the figure), and the guiding plate 71 can rotate around the rotating shaft within a preset angle range under the drive of the driving cylinder 73.

[0066] In one embodiment, the detection device 74 adopts an existing visual detection device to perform preliminary detection and rejection of the package during the conveying process, which can effectively improve the meat product processing efficiency.

On the basis of Embodiment 3, in this embodiment, the material guiding structure 7 further includes a material guiding roller 75, and the material guiding roller 75 is rotatably installed at the discharging end of the conveying plate 11.

[0069] The material guiding roller 75 is provided with a material guiding groove 751, and the detection device 74 is arranged above the material guiding roller 75 through a bracket. During use, the material guiding groove 751 receives the packaged products on the conveying plate 11. When the material guiding groove 751 rotates to the upper position, the detection device 74 detects the package. When the material guiding groove 751 rotates to the discharging position (towards the material guiding plate 71), the package is introduced onto the material guiding plate 71. When the material guiding groove 751 drives the package to rotate to the detection station, it can pause for a certain time to enable the package to be inspected in a stationary state, which is beneficial to improving the detection effect.

[0070] Optionally, a driving motor 76 is installed on the baffle 16, and the power output end of the driving motor 76 is connected to the material guiding roller 75, and the driving motor 76 drives the material guiding roller 75 to rotate.

[0071] Optionally, there are two material guiding grooves 751 symmetrically arranged with respect to the center of the material guiding roller 75.

[0072] Embodiment 5

[0073] An embodiment of the present invention provides a packaging and conveying device for meat product processing. In this embodiment, a plurality of partition strips 18 are arranged on the conveying plate 11, and the partition strips 18 divide the conveying plate 11 into a plurality of independent conveying channels. A set of material guiding structures 7 are correspondingly arranged at the output end of each conveying channel, and the material guiding structure 7 is the material guiding structure 7 described in Embodiment 2, 3 or 4.

[0074] The following takes the material guiding structure described in Embodiment 4 as an example for illustration.

[0075] A material guiding roller 75 is correspondingly arranged at the output end of each conveying channel, and a material guiding plate 71 is correspondingly arranged on one side of each material guiding roller 75, and the material guiding plates 71 are respectively rotatably arranged through driving cylinders 73.

[0076] The number of conveying channels can be set according to requirements. Exemplarily, three partition strips 18 are adopted, so as to form four conveying channels on the conveying plate 11. The driving motor 76 is installed on the outer wall of a baffle 16, and its power output end is connected to one end of a rotating shaft. The other end of the rotating shaft is rotatably connected to another baffle 16. Four material guiding rollers are installed on the rotating shaft between the two baffles 16, and the four material guiding rollers respectively correspond to the discharging ends of the four conveying channels. A material guiding plate 71 is hinged respectively below one side of the four material guiding rollers. The collecting box 72 can be one and is arranged below the multiple material guiding rollers 75 (of course, the collecting box can also be independently arranged), and a driving cylinder 73 is hinged respectively at the bottom of the material guiding plate 71. During use, the detection device 74 above the material guiding roller 75 can quickly scan the packages in each material guiding groove 751, and after scanning, it can judge whether they meet the requirements according to the preset standards, and when unqualified ones are encountered, the corresponding material guiding plate will be adjusted to rotate downward. The multi-channel parallel processing can effectively improve the processing efficiency, and the packages can be neatly conveyed along the preset path to facilitate the subsequent cleaning by the cleaning structure 5.

[0077] Optionally, a detection device 74 can also be correspondingly arranged above each material guiding roller 75.

[0078] Optionally, the number of the first nozzles 23 can also correspond one by one to the number of the conveying channels, that is, the distribution positions of the first nozzles 23 correspond to the conveying channels on the conveying plate 11.

[0079] It should be noted that in the drawings of the present invention, the conveying plate schematically shows a multi-conveying-channel structure, and the corresponding material guiding structure is also in multiple groups. In actual applications, the conveying channels can be set as a single-channel structure. Moreover, the positions of the spraying structure, the refrigerating structure, the cleaning structure and the material guiding structure are only schematically shown. The spraying structure only needs to be located upstream of the first conveying mechanism, the refrigerating structure is located above the first conveying mechanism, and the material guiding structure is located between the first conveying mechanism and the second conveying mechanism. It should be understood that the positions of the components are schematic, and their sizes are also schematic, and are only used for expressing the idea of the technical solution, and do not involve the specific positions and sizes in the actual embodiments.

[0080] Embodiment 6

[0081] An embodiment of the present invention provides a material guiding plate. The material guiding plate 71 includes: a first rod body 711 and a second rod body 712 arranged in parallel, and a plurality of connecting rods 713 connected between the two rod bodies. There is a gap between adjacent connecting rods 713, and this gap forms a drainage groove 710. A first cooling channel 714 is provided inside the first rod body 711 and the second rod body 712, and a second cooling channel 715 communicating with the first cooling channel 714 is provided inside the connecting rod 713. A first pipeline 716 is connected to the second rod body 712, and a second pipeline 717 is connected to the first rod body 711. During use, the cooling system inputs cooling liquid or gas into the first cooling channel 714 of the first rod body 711, and then the medium is discharged through the second pipeline 717. In this way, the package can also be continuously cooled when passing through the material guiding plate 71, which is also beneficial to further ensure the cooling effect of the package.

[0082] When the material guiding plate 71 is used in Embodiment 3, the first pipeline 716 and the second pipeline 717 adopt telescopic pipes. When the material guiding plate 71 rotates driven by a driving cylinder, the telescopic pipes expand and contract synchronously with the material guiding plate 71.

[0083] As an implementation scenario, in this scenario, the cooling channel can be connected to the refrigeration cavity 112, that is: the external cooling system is connected to the first pipeline 716, and the second pipeline 717 is connected to the cooling inlet of the refrigeration cavity 112 through a connecting pipeline. During use, the cooling system inputs cooling liquid or gas into the first cooling channel 714 of the first rod body 711, and the cooling medium enters the refrigeration cavity 112 after passing through the cooling channel and the connecting pipeline. On the one hand, the package can be continuously cooled when contacting the material guiding plate, accelerating the cooling effect of the package. On the other hand, a closed-loop system can be formed with the refrigeration cavity 112 to improve the utilization rate of cold energy. It should be noted that the cooling system adopts the prior art. The cooling system is used to pump the refrigerated water or gas into the cooling channel. A temperature sensor can be set in the refrigeration cavity 112. When the temperature of the water or gas in the refrigeration cavity 112 exceeds the preset value, it is discharged from the cooling medium outlet for cooling and then recycled. Optionally, the waste water recovered by the recovery cavity can be pumped into the cooling channel after being cooled. Of course, in other implementation scenarios, the refrigeration cavity and the cooling channel can also be respectively connected to a cooling system.

[0084] The material guiding plate in this embodiment can be used in any of the implementation manners in the above-mentioned Embodiments 2-5.

[0085] Embodiment 7

[0086] An embodiment of the present invention provides a cleaning structure for a packaging conveying device. The cleaning structure includes: a mounting seat 51, an electromagnet 52, a slider 53, a spring 54, a clamping plate 55 and a flexible cleaning member 56.

[0087] The mounting base 51 is horizontally arranged above the second conveying mechanism 4. A chute 511 is provided on the lower surface of the mounting base 51. An electromagnet 52 is arranged in the chute 511 and is located at the middle position of the chute 511. Sliders 53 that can cooperate with the electromagnet 52 are respectively arranged on both sides of the electromagnet 52. The sliders 53 are slidably connected to the chute 511, and one side of the slider 53 is connected to the electromagnet 52 through a spring 54. When the electromagnet 52 is energized to generate magnetic force, the electromagnet 52 can generate an attractive force on the slider 53 to make it approach the electromagnet 52. The bottom of the slider 53 is connected to a clamping plate 55. One end of the clamping plate 55 is connected to the bottom of the slider 53, and the other end extends below the mounting base 51. A flexible cleaning member 56 is arranged between the two clamping plates 55, and the flexible cleaning member 56 is connected between the two clamping plates 55 in a compressible state.

[0088] Optionally, the flexible cleaning member 56 is a porous water-absorbing sponge.

[0089] During use, when the package is imported onto the second conveying mechanism 4 from the guide plate 71, the package passes under the lower surface of the flexible cleaning member driven by the second conveying mechanism 4. First, the flexible cleaning member 56 of the first set of cleaning structures wipes the water stains on the surface of the package clean. Then, after the turning mechanism 41 turns the package over, the flexible cleaning member of the second set of cleaning structures dries the water stains on the surface of the package after turning. When the flexible cleaning member 56 has been used for a certain period of time or has adsorbed a certain amount of water, the electromagnet 52 is energized. After the electromagnet 52 is energized, it generates an attractive force, so that an attractive force can be generated on the two sliders 53, causing the two sliders 53 to approach the electromagnet 52. Thus, the sliders 53 drive the two clamping plates 55 to approach each other to squeeze out the water in the flexible cleaning member 56 between the two clamping plates 55, and the squeezed water drops into the second conveying mechanism 4.

[0090] Optionally, the energization or de-energization of the electromagnet 52 can be regulated by a controller. Exemplarily, a clock program is preset in the controller. When the package is conveyed for a certain period of time, the conveying mechanism stops conveying briefly, and then the controller automatically regulates the electromagnet 52 to be energized, and then the water in the flexible cleaning member is squeezed out under the action of the clamping plates 55.

[0091] Optionally, the second conveying mechanism 4 includes a mounting frame and a plurality of conveying rollers rotatably arranged in the mounting frame. An opening is provided on one side of the mounting frame close to the guiding structure 7, and the mounting frame is communicated with the collection box 72 through this opening. In this way, the squeezed water falls into the mounting frame through the gaps between the conveying rollers and then flows into the collection box 72.

[0092] In one embodiment, when the conveying device uses multiple channels for conveying, that is, when using the multiple independent conveying channels described in Embodiment 5, a cleaning structure 5 is respectively arranged corresponding to each conveying channel. Among them, as an implementation scenario, in this scenario, the mounting base 51 is independently arranged. Exemplarily, four mounting bases 51 are respectively arranged corresponding to the four conveying channels, and each mounting base 51 is respectively provided with a chute 511 with an open bottom. An electromagnet 52, a slider 53, a spring 54, a clamping plate 55 and a flexible cleaning member 56 are respectively arranged in the chute 511. As another implementation scenario, in this scenario, there is one mounting base 51, and the number of chutes 511 opened on the mounting base 51 is adapted to the number of conveying channels. Exemplarily, four chutes 511 are opened on the mounting base 51, and an electromagnet 52, a slider 53, a spring 54, a clamping plate 55 and a flexible cleaning member 56 are respectively arranged in the four chutes. The attached drawings of the cleaning structure of the present invention are mainly shown schematically in this scenario.

[0093] Optionally, multiple groups of sliders 53 and springs 54 can be arranged in each chute 511, and can be arranged according to the length of the flexible cleaning member 56 to ensure that the clamping force generated by the clamping plate 55 can better squeeze out water.

[0094] In one embodiment, the height of the flexible cleaning member 56 can be adjusted, that is, the height of the mounting base 51 can be adjusted. By adjusting the height of the mounting base 51, the distance between the bottom flexible cleaning member 56 and the second conveying mechanism 4 can be adjusted. During use, it can be adaptively adjusted according to the height of different products, so that the flexible cleaning member 56 can better contact the packaging surface, thereby ensuring the water wiping effect.

[0095] Optionally, one or more mounting bases 51 are installed on a mounting platform 57, the mounting platform 57 is connected to a lifting mechanism 58, and the lifting mechanism 58 is drivingly connected to the mounting platform 57. The mounting platform 57 can move up or down under the drive of the lifting mechanism 58.

[0096] Optionally, the mounting platform 57 is of a rectangular frame structure.

[0097] Optionally, the lifting mechanism 58 includes: a base plate 581, a screw rod 582, a driving member 583, a guiding column 584, and a lifting slider 585. The base plate 581 is installed on the mounting frame of the second conveying mechanism 4. The screw rod 582 is installed on the base plate 581. One end of the screw rod 582 is connected to the driving member 583. Guiding columns 584 are fixed on the base plate 581 on both sides of the screw rod 582. The lifting slider 585 is threadedly connected to the screw rod 582 and slidably sleeved on the guiding column 584. One side of the mounting platform 57 is connected to the lifting slider 585. As an implementation scenario, in this scenario, the driving member 583 is a rotating wheel. During use, by rotating the rotating wheel, the lifting slider 585 moves upward or downward along the screw rod 582 and the guiding column 584, so as to adjust the height of the mounting platform 57. As another implementation scenario, in this scenario, the driving member 583 is a driving motor (not shown in the figure). The screw rod 582 can be a ball screw. One end of the ball screw is connected to the power output end of the driving motor. During use, the driving motor is started, and the driving motor drives the ball screw to rotate, so that the lifting slider 585 moves upward or downward along the screw rod 582 and the guiding column 584.

[0098] Existing devices generally lack the automatic cleaning function for the packaging surface and cannot effectively remove the blood stains and grease residues during the packaging process. These deficiencies not only affect the hygienic quality of the products, but also affect the subsequent labeling and inkjet coding processes. Through the setting of the above cleaning structure, the present invention can not only dry the packaging to ensure that there is no water residue on the packaging, but also clean the stains and sundries attached to the packaging surface to ensure the cleanliness of the packaging and thus improve the quality of the products. At the same time, the water adsorbed by the flexible cleaning member can be quickly squeezed out under the action of the electromagnet and the clamping plate, which is convenient to use.

[0100] The embodiment of the present invention provides a refrigeration structure for a packaging conveying device. The refrigeration structure includes a plurality of air supply pipes 31 and a plurality of groups of cooling components 32 arranged in the air supply pipes 31.

[0101] Specifically, a plurality of air supply pipes 31 are arranged on the housing 12. Their air outlet ends penetrate through the top of the housing 12 and extend towards the conveying plate 11. Their air inlet ends are connected to the air supply system. In this embodiment, a plurality of groups of cooling components 32 are respectively arranged at intervals in each air supply pipe 31, and the adjacent cooling components 32 are alternately staggered along the air flow direction. Exemplarily, each air supply pipe 31 adopts at least two groups of cooling components 32. The two cooling components 32 are respectively arranged on both sides of the air supply pipe 31 and are spaced and staggered.

[0102] Further, the temperature reduction component 32 includes a refrigerating body 321 and a cold conduction fin 322. The cold end of the refrigerating body 321 extends into the air supply duct 31 and is connected to the cold conduction fin 322 arranged in the air supply duct 31. The hot end of the refrigerating body 321 is arranged outside the air supply duct 31 and is connected with a radiator and / or a fan. Optionally, the refrigerating body 321 can adopt a semiconductor, and the cold conduction fin 322 can adopt a ceramic cold conduction fin. Through the arrangement of the temperature reduction component 32, the cold air conveyed by the air supply system can be cooled again, ensuring that the temperature of the air sent to the packaging surface is relatively low and improving the refrigeration effect.

[0103] Embodiment 9

[0104] The embodiment of the present invention application provides a packaging conveying device for meat product processing. In this embodiment, it further includes an air extraction structure which is communicated with the inside of the housing 12. Through the cooperation of the air extraction structure and the air supply duct 31, the air circulation in the housing 12 can be enhanced. When adding the temperature reduction component 32, the heat generated by the radiator or the fan at the hot end of the refrigerating body 321 can be discharged.

[0105] Optionally, the air extraction structure includes an air extractor (not shown in the figure) installed on the top and / or side of the housing 12.

[0106] Embodiment 10

[0107] Since there will be certain dust impurities in the air, in order to reduce the influence of dust on the air extractor during the use of the air extraction structure, in this embodiment, on the basis of Embodiment 9, referring to Figure 11 As shown, a plurality of ventilation holes 121 are opened on the top wall and / or both side walls of the housing 12, and filter sheets 122 are arranged in the ventilation holes 121; the air extraction structure includes an air extractor and an air extraction hood 81. The air extraction hood 81 is installed on the outer wall of the housing 12 corresponding to the ventilation holes 121. The air extractor is communicated with the air extraction hood 81 through an air duct 82. One side of the air extraction hood 81 is provided with an opening, and a movable plate 83 is hinged at the opening. The movable plate 83 can rotate clockwise under the action of thrust and is in sealing cooperation with the air extraction hood 81 in the static state.

[0108] Further, a second spraying structure 9 is arranged below the movable plate 83. The second spraying structure 9 includes a second spraying pipe 91 and a plurality of second spray heads 92 arranged on the second spraying pipe 91. The second spraying pipe 91 is connected to an external water source through a pipeline. A telescopic cylinder is arranged at the bottom of the second spraying pipe 91. The movable end of the telescopic cylinder 93 is connected to the second spraying pipe 91, and the telescopic cylinder 93 can drive the second spraying pipe 91 to move up or down. During use, the second spray heads 92 can make the positions of the second spray heads 92 correspond to the positions of the ventilation holes 121 under the drive of the telescopic cylinder 93.

[0109] Optionally, the number of the second spray heads 92 is the same as the number of the ventilation holes 121.

[0110] During use, turn on the exhaust fan. The ventilation hole 121 can suck away the dust generated inside the housing 12. When the dust-containing air passes through the ventilation hole 121, the filter sheet 122 can intercept most of the dust, and the atomized water vapor from the first nozzle 23 will cause some dust to form slag on the surface of the filter sheet. When the accumulation reaches a certain level, the telescopic cylinder 93 can be activated. The telescopic cylinder 93 drives the second spray pipe 91 to rise. The movable plate 83 will rotate clockwise around the hinge end under the push of the second spray pipe 91 until the second spray pipe 91 extends into the air extraction hood 81 and makes the second nozzle 92 correspond to the ventilation hole 121. Then, by pumping external water source into the second spray pipe 91 and spraying it from the second nozzle 92 to the filter sheet 122, the second nozzle 92 sprays a stronger water flow to blow out the slag ash on the filter sheet 122. The waste water falls onto the conveying plate 11 and is discharged through the drain hole 113. It should be noted that when cleaning the dust on the filter sheet, the feeding mechanism 6 can temporarily stop the conveying of the package first. Through the setting of the second nozzle 92, not only can the dust on the filter sheet 122 be cleaned, but also the conveying plate 11 can be cleaned. Through the setting of the filter sheet 122 and the second spraying structure 9, it is beneficial to ensure the continuous and stable operation of the exhaust fan.
