Description

[0002] The packaging conveying device for meat product processing is mainly used for conveying products after packaging to designated processes (such as detection, labeling, boxing, etc.). Due to the residual heat of the heat sealing process and the initial temperature of the products, the surface temperature of the products after packaging is generally high. For example, beef and mutton packaged by an automatic vacuum packaging machine, or meat paste products (heat sealing process temperature plus the temperature of the material inside the filling container) after being filled and heat sealed, therefore, if there is no efficient immediate cooling, high-temperature packaging can easily create favorable conditions for microbial reproduction during the conveying process, and can also cause the heat sealing port to soften, thereby affecting the product quality.

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Example 1

[0052] like Figures 1-10 As shown in the figure, an embodiment of the present invention 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.

[0053] The first conveying mechanism 1 includes a conveying plate 11 and a housing 12 covering the conveying plate 11. The conveying plate 11 is inclined from upstream to downstream. The conveying plate 11 has a recycling chamber 111 and a cooling chamber 112 that are isolated from each other. A number of drainage holes 113 connected to the recycling chamber 111 are opened on the downstream surface of the conveying plate 11.

[0054] The upstream inlet of the second conveying mechanism 4 is connected to the downstream outlet of the first conveying mechanism 1. The first spraying structure 2, the refrigeration structure 3, and the cleaning structure 5 are arranged sequentially according to the meat product packaging conveying direction. Specifically, the first spraying structure 2 is installed above the upstream of the conveyor plate 11 and is used to spray the surface of the meat product packaging during conveying; the refrigeration structure 3 includes an air supply duct 31 connected to the inside of the shell 12 and is used to air-cool the package after spraying; the cleaning structure 5 is set on the second conveying mechanism 4 and is used to wipe and clean the surface of the cooled package.

[0055] Optionally, the refrigeration cavity 112 is arranged outside the recovery cavity 111, and a plurality of drain holes 113 are arranged below the recovery cavity 111, and a collection groove 13 is arranged below the plurality of drain holes 113, and the collection groove 13 is connected and communicated with the refrigeration cavity 112 through a flow guide pipe 14. The recovery cavity 111 is connected with a drain pipe 15 for draining the water backflow to the outside for recycling. The refrigeration cavity 112 is provided with a cooling medium inlet and a cooling medium outlet. In use, the cooling medium inlet is connected and communicated with an external cooling system, so that the cooling system inputs cooling liquid or gas into the refrigeration cavity 112, so as to cool the conveying plate 11 and the recovery cavity 111. When the temperature of the cooling medium is increased, the cooling medium is discharged through the cooling medium outlet for recycling. By integrating the refrigeration cavity 112 in the conveying plate 11, the refrigeration cavity can reduce the temperature of the plate surface, and the temperature of the plate surface is uniform. On the one hand, the refrigeration effect of the conveying plate during the whole conveying process can be ensured, the cooling speed can be increased, and the overheating of the bottom of the package can be avoided. On the other hand, the water with increased temperature after spraying is recovered to the recovery cavity 111, and the water in the recovery cavity 111 is pre-cooled by the refrigeration cavity 112 outside, so that the recycling and cooling efficiency of the water can be increased.

[0056] Optionally, the first conveying mechanism 1 further comprises a baffle 16 arranged on both sides of the upper surface of the conveying plate 11, and a supporting leg 17 arranged at the bottom of the conveying plate 11.

[0057] Optionally, the bottom end of the shell 12 is connected with the corresponding baffle 16, and the left input end and the right output end of the shell 12 can be a full opening structure or a half opening structure. The half opening structure can reduce the loss of the cooling medium. The two ends shown in the figure are full opening structures.

[0058] In 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, and the water flows along the conveying plate 11 and flows into the recovery cavity 111 through the drain hole 113. The package after spraying enters the shell 12 immediately, and the airflow conveyed by the refrigeration structure 3 to the inside of the shell 12 can further cool the package. Then, the package enters the second conveying mechanism 4, and in the conveying process of the second conveying mechanism 4, the cleaning structure 5 can not only wipe 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 to ensure the cleanliness of the package and improve the quality of the product. In actual application, spraying and air cooling can be selected according to needs, for example, when it is necessary to clean the package simultaneously, only the first spraying structure 2 can be selected.

[0059] In an embodiment, the first conveying mechanism 1 of the present application can be assembled below a vacuum packaging machine or a can, that is, the vacuum packaging machine or the can is arranged above the upstream feeding end of the conveying plate 11, and the product package can enter the conveying plate 11 after being completed.

[0060] In an embodiment, after the meat products are packaged by the vacuum packaging machine or the emulsion products are bagged and sealed by the canner, the products can be conveyed to the conveying plate 11 by the feeding mechanism 6. The downstream discharging end of the feeding mechanism 6 is connected to the upstream feeding end of the conveying plate 11. In use, the products can be pushed to the conveying plate 11 by the pushing mechanism. That is, the vacuum packaging machine or the canner is located above the feeding mechanism 6, and after the packaging of the products is completed, the products are placed on the feeding mechanism 6, and then the pushing mechanism pushes the products to the conveying plate 11. Of course, the feeding mechanism 6 can also be a conveying belt conveying mechanism or a conveying roller conveying mechanism. The feeding mechanism 6 is used to convey the products that need to be cooled and cleaned. Those skilled in the art can make settings according to actual needs.

[0061] In an embodiment, the conveying plate 11 can directly adopt a plate body (sliding plate) structure. Because of the arrangement of the first spraying structure 2, the sprayed clean water can increase the lubricity of the conveying plate body. In another embodiment, a conveying belt can also be arranged on the conveying plate 11. The conveying belt is provided with filter holes to facilitate the flow of the sprayed liquid into the recovery cavity 111 through the drainage hole 113. The conveying roller is arranged around the outer periphery of the conveying plate 11 and is driven by the driving roller. The conveying belt and its driving mode are mature prior art, and thus will not be described in detail.

[0062] In an embodiment, the first spraying structure 2 includes a mounting plate 21, a first spraying pipe 22, and a plurality of first nozzles 23. The mounting plate 21 is arranged above the conveying plate 11 by being connected to the baffle 16 on the first conveying mechanism 1. The first spraying pipe 22 is arranged on the top of the mounting plate 21. A plurality of branch pipes are uniformly distributed along the length direction of the first spraying pipe 22 and are connected to the first spraying pipe 22. A plurality of first nozzles 23 are arranged on the branch pipes. In use, an external cooling water source is connected to the first spraying pipe 22. The water pump draws the cooling water into the first spraying pipe 22 and sprays the cooling water through the first nozzles 23.

[0063] Optionally, the first nozzles 23 adopt atomizing nozzles. The water mist sprayed by the first nozzles 23 can simultaneously achieve the cooling and cleaning of the packaging.

[0064] Optionally, the mounting plate 21 is adjustably arranged. For example, the mounting plate 21 is slidably connected to the baffle 16 on both sides. When the mounting plate 21 is slid to a specified position, the mounting plate 21 is fixed by fixing bolts. In use, the mounting plate 21 can flatten the packaging to prevent the packaging from being stacked. The adjustably arranged mounting plate 21 facilitates the matching of packaging of different heights and the height adjustment of the first nozzles 23.

[0065] In an embodiment, the refrigeration structure 3 comprises a plurality of air supply pipes 31, the air inlets of the air supply pipes 31 are connected with the existing air supply system, and the air supply system supplies cooling air flow to the plurality of air supply pipes 31. The air outlets of the air supply pipes 31 penetrate the shell 12 and extend above the conveying plate 11. By extending the air supply pipes 31 above the conveying plate 11, the cooling effect can be improved.

[0066] In an embodiment, the second conveying mechanism 4 is provided with a turnover mechanism 41, and a set of cleaning structures 5 is arranged on each side of the turnover mechanism 41. The turnover mechanism 41 is used for turning over the package. After the surface of the package is wiped and cleaned by a set of cleaning structures 5, the turnover mechanism 41 turns over the package, and then another set of cleaning structures 5 wipes and cleans the other surface of the package. As an example, in an implementation scenario, the second conveying mechanism 4 adopts a conveying roller conveying mechanism, the turnover mechanism 41 adopts a turnover driving roller, a servo motor for driving the turnover driving roller to rotate in the opposite direction of the conveying rollers inside the second conveying mechanism 4 is mounted on the outer wall of the second conveying mechanism 4, and the turnover driving roller is rotatably connected to the inner wall of the frame of the second conveying mechanism 4 at both ends. The servo motor drives the turnover driving roller to rotate in the opposite direction, so that the turnover driving roller and the conveying rollers inside the second conveying mechanism 4 rotate in opposite directions, thereby turning over the package in the conveying process and wiping and cleaning the back surface of the package. Anti-skid lines can be arranged on the outer wall of the turnover driving roller to increase the friction and facilitate the turnover. In other embodiments, the turnover mechanism 41 can also adopt other existing technologies, such as a mechanical hand, etc.

[0068] The packaging conveying device for meat product processing provided in the embodiments of the present application further comprises a material guiding structure 7 between the first conveying mechanism 1 and the second conveying mechanism 4.

[0069] The material guiding structure 7 comprises a material guiding plate 71 and a collection box 72. The material guiding plate 71 is arranged obliquely between the first conveying mechanism 1 and the second conveying mechanism 4, a plurality of drainage grooves 710 are arranged on the material guiding plate 71, and the collection box 72 is arranged below the material guiding plate 71 and is provided with a drainage hole at the bottom. In use, the package output from the downstream of the conveying plate 11 falls onto the second conveying mechanism 4 through the material guiding plate 71, and the water attached to the package can flow into the collection box 72 through the drainage grooves 710 when the package passes through the material guiding plate 71, thereby reducing the water entering the second conveying mechanism.

[0070] Optionally, the side of the shell 12 close to the material guiding structure 7 extends towards the material guiding structure 7, that is, the material guiding structure 7 is covered in the shell 12.

[0071] Optionally, the air supply pipe 31 of the refrigeration structure 3 is multiple, and at least one air supply pipe 31 is arranged above the collecting box 72. Of course, multiple air supply pipes 31 can also be arranged above the collecting box 72 along the width direction of the shell 12, and the specific arrangement can be set according to the width of the conveying plate 11. When the package passes through the guide plate 71, most of the water on the package can be blown off through the air supply pipe 31.

[0072] Embodiment 3

[0073] The packaging conveying device for meat product processing provided in the embodiments of the present application further comprises a driving cylinder 73 and a detection device 74 on the basis of Embodiment 2.

[0074] In the present embodiment, the driving cylinder 73 is installed in the collecting box 72, and the detection device 74 is installed at the discharging end of the conveying plate 11 downstream, for preliminary visual detection of the packaging product. One end of the guide plate 71 is hinged to the discharging 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 guide plate 71. The driving cylinder 73 can drive the guide plate 71 to rotate around the hinged end, so that the end of the guide plate 71 away from the hinged end faces the second conveying mechanism 4 or the collecting box 72, that is, when the driving cylinder 73 is not in action, the guide plate 71 is in the initial inclined state and faces the second conveying mechanism 4, so as to guide the package to the second conveying mechanism 4; when the driving cylinder 73 is in action, the driving cylinder 73 drives the guide plate 71 to rotate clockwise downward around the hinged end to the inclined state and faces the bottom of the collecting box 72, so as to guide the package into the collecting box 72.

[0075] Further, the detection device 74 is used to detect whether the package is qualified, and the driving cylinder 73 and the detection device 74 are both electrically connected to the controller. The controller receives the detection signal of the detection device 74 and judges whether the package is qualified. When the package is qualified, the driving cylinder 73 is not in action, that is, the package is guided into the second conveying mechanism 4; when the package is not qualified, the driving cylinder 73 is controlled to be in action, so as to guide the unqualified package into the collecting box 72.

[0076] The guide plate 71 can be connected to the discharging end of the conveying plate 11 through a rotating shaft (not shown in the figure), and the guide plate 71 can rotate around the rotating shaft within a preset angle range under the driving of the driving cylinder 73.

[0077] In an embodiment, the detection device 74 adopts an existing visual detection device. The visual detection device is used to preliminarily detect and reject the package during the conveying process, which can effectively improve the processing efficiency of the meat product.

[0080] The material guiding groove 751 is arranged on the material guiding roller 75, and the detection device 74 is arranged above the material guiding roller 75 through a support.

[0098] The mounting base 51 is horizontally arranged above the second conveying mechanism 4, and a sliding groove 511 is arranged on the lower surface of the mounting base 51. An electromagnet 52 is arranged in the sliding groove 511, and the electromagnet 52 is arranged at the middle position of the sliding groove 511.

[0099] Optionally, the flexible cleaning piece 56 is a porous water-absorbing sponge.

[0100] In use, when the package is guided onto the second conveying mechanism 4 from the guide plate 71, the package passes through the lower surface of the flexible cleaning piece under the driving of the second conveying mechanism 4. First, the flexible cleaning piece 56 of the first cleaning structure wipes the water stains on the surface of the package, and then the second cleaning structure wipes the water stains on the surface of the package after the turning-over mechanism 41 turns over. When the flexible cleaning piece 56 is used for a certain period of time or absorbs a certain amount of water, the electromagnet 52 is powered.

An opening is arranged on the side of the mounting frame close to the guide structure 7, and the mounting frame is connected with the collecting box 72 through the opening. In this way, the squeezed-out water falls into the mounting frame through the gap between the conveying rollers, and then flows into the collecting box 72.

[0103] In an embodiment, when the conveying device adopts multi-channel conveying, i.e. multiple independent conveying channels as described in Embodiment 5, a cleaning structure 5 is arranged for each conveying channel. As an implementation scenario, four conveying channels are arranged with four mounting seats 51 respectively, each of which is provided with a bottom opening sliding groove 511, and the sliding groove 511 is arranged with an electromagnet 52, a sliding block 53, a spring 54, a clamping plate 55 and a flexible cleaning piece 56. As another implementation scenario, the mounting seat 51 is one, and the mounting seat 51 is provided with a number of sliding grooves 511 corresponding to the number of conveying channels, for example, four sliding grooves 511 are arranged on the mounting seat 51, and the four sliding grooves are arranged with an electromagnet 52, a sliding block 53, a spring 54, a clamping plate 55 and a flexible cleaning piece 56. The drawings of the cleaning structure of the present application are mainly given in this scenario.

[0104] Optionally, the sliding block 53 and the spring 54 in each sliding groove 511 can be provided with multiple groups, which can be set according to the length of the flexible cleaning piece 56 to ensure that the clamping force generated by the clamping plate 55 can better extrude water.

[0105] In an embodiment, the height of the flexible cleaning piece 56 can be adjusted, i.e. the height of the mounting seat 51 can be adjusted, so that the distance between the bottom flexible cleaning piece 56 and the second conveying mechanism 4 can be adjusted. During use, the height can be adjusted according to the height of different products to make the flexible cleaning piece 56 better contact with the packaging surface, thereby ensuring the water stain wiping effect.

[0106] Optionally, one or more mounting seats 51 are installed on a mounting platform 57, the mounting platform 57 is connected with a lifting mechanism 58, the lifting mechanism 58 is drivingly connected with the mounting platform 57, and the mounting platform 57 can move upward or downward under the driving of the lifting mechanism 58.

[0107] Optionally, the mounting platform 57 is a rectangular frame structure.

[0108] Optionally, the lifting mechanism 58 comprises a base plate 581, a screw rod 582, a driving member 583, guide columns 584 and a lifting slider 585. The base plate 581 is mounted on the mounting frame of the second conveying mechanism 4, the screw rod 582 is mounted on the base plate 581, one end of the screw rod 582 is connected with the driving member 583, the guide columns 584 are fixed on the base plate 581 at both sides of the screw rod 582, the lifting slider 585 is threadedly connected with the screw rod 582 and is sleeved on the guide columns 584, and one side of the mounting platform 57 is connected with the lifting slider 585. As an implementation scenario, in this scenario, the driving member 583 is a rotating wheel, in use, the rotating wheel is rotated to move the lifting slider 585 upward or downward along the screw rod 582 and the guide columns 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), and the screw rod 582 can adopt a ball screw, one end of the ball screw is connected with the power output end of the driving motor, in use, the driving motor is started, the driving motor drives the ball screw to rotate, so as to move the lifting slider 585 upward or downward along the screw rod 582 and the guide columns 584.

[0109] The existing device generally lacks an automatic cleaning function for the packaging surface, and cannot effectively remove blood stains and grease remaining in the packaging process. These deficiencies not only affect the product hygiene quality, but also affect the subsequent labeling and code spraying processes. Through the arrangement of the cleaning structure, the packaging can be wiped dry to ensure that no water remains on the packaging, and the stains and sundries attached to the packaging surface can also be cleaned to ensure the cleanliness of the packaging and improve the quality of the product. 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.
