The main functions of a food packaging machine include filling, wrapping, sealing, etc. These processes are the core links in the packaging process. In addition, packaging also includes processes such as metering or stamping on the package. According to different functions, food packaging machines can be divided into single-function packaging machines and multi-function packaging machines; according to the purpose of use, they can be divided into inner packaging machines and outer packaging machines; according to the type of packaging, they can be divided into special packaging machines and general packaging machines; according to the level of automation, they can be divided into semi-automatic machines and fully automatic machines, etc. The forming-filling-sealing packaging machine is a multi-function packaging machine that integrates multiple functions, such as forming, filling, sealing, etc.
[0003] In the prior art, after a food packaging machine packages food, the packaged food will be piled up at the exit of the food packaging machine. Usually, when a conveying device is used to transport the food after packaging, the packaged food is also piled up for transportation. At this time, when the staff conducts inspection on the packaged food, they need to spend extra time and energy to arrange and sort the packaged food piled up. Moreover, when a packaged food has a leaking package during inspection, the packaged food piled up is not easy to trace back to the specific problematic package, and it takes time to find when the leaking package problem occurs, which will affect the packaging efficiency of the food. Summary of the invention
[0004] In view of the deficiencies in the prior art, the present invention provides an automatic product placement and arrangement device for a food packaging machine to solve the problems raised in the above-mentioned background technology.
[0005] The above technical objectives of the present invention are achieved through the following technical solutions: The food packaging machine of claim 1, wherein the food packaging machine body is provided with a conveying frame on one side of the food packaging machine body, and an auxiliary plate is fixedly installed on the top surface of the conveying frame; an interval arrangement component is arranged on one side of the conveying frame for arranging and conveying the packaged food in an interval manner, and the interval arrangement component comprises: a mounting block, the mounting block is fixedly installed on one side of the conveying frame, a stabilizing block is fixedly installed on one side of the conveying frame, a fixing block is fixedly installed on one side of the conveying frame, a supporting hole is provided on the top surface of the fixing block, a connecting column is movably sleeved on the inner circular wall surface of the supporting hole, a rotating block is fixedly installed on the top surface of the connecting column, a plurality of blocking columns are fixedly installed on the outer circular wall surface of the rotating block, a connecting disk is fixedly installed on the bottom surface of the connecting column, a plurality of limiting grooves are provided on the outer circular wall surface of the connecting disk, a swing column is provided on the bottom surface of the stabilizing block, and one end of the swing column is fixed A card block is installed, and the card block is movably sleeved with the limiting groove, a pushing column is fixedly installed at one end of the swing column, a rotating hole is opened on the top surface of the swing column, and a positioning column is fixedly installed on the bottom surface of the stabilizing block, the positioning column is movably sleeved with the rotating hole, a movable hole is opened on the top surface of the stabilizing block, a rotating column is movably sleeved on the inner circular wall surface of the movable hole, a rotating block is fixedly installed on the bottom surface of the rotating column, and a protrusion is fixedly installed on the outer circular wall surface of the rotating block; a reset component for rebounding the swing column is provided on one side of the stabilizing block; a driving component for rotating the rotating column is provided on the bottom surface of the mounting block; a detection component for checking air leakage of food packaging is provided on the top surface of the conveying frame; a distinguishing component for detecting and distinguishing food packaging is provided on one side of the conveying frame; conveying components for conveying packaged food are respectively provided on both sides of the interior of the conveying frame.
[0006] By adopting the above technical solution, by setting a blocking column, after the food is packaged by the food packaging machine body, the packaged food will fall on the conveying frame and be transmitted by the conveying component, and then the packaged food will be blocked by the blocking column after reaching the position of the blocking column, and then the driving component is used to drive the rotating column, the rotating block and the protrusion to rotate. When the protrusion rotates in a circle with the rotating block, the position of the protrusion changes continuously. When the position of the protrusion rotates to the position of the pushing column, the protrusion squeezes and pushes the pushing column. After the pushing column is subjected to the squeezing force, the pushing column pushes the swinging column to make the swinging column The tail end rotates around the positioning column, and then the swing column drives the block to move when rotating, so that the block can be moved out of the limiting groove, and then the restriction of the block to the connecting disk can be released. At this time, when the conveying component drives the packaged food to continue to move, the packaged food will push the blocking column during the movement, and then the blocking column will drive the rotating block, the connecting column and the connecting disk to rotate. When the packaged food is on the top surface of the conveying frame, the two blocking columns are V-shaped, which can limit it in the middle of the V and block it. When the blocking column rotates, the blocked packaged food will be released to allow it to continue to be conveyed. Then the next packaged food will enter another V-shaped center formed by the rotation of multiple blocking columns and be blocked by the blocking columns. Because the rotating block and the protrusion can only make one circle to allow the swing column to drive the block to move out of the limiting groove to release the restriction on the connecting disk, so that the connecting disk, the connecting column, the rotating block and the blocking column can rotate freely, and then the blocking column and the rotating block can only rotate once. Therefore, only one packaged food can pass through each rotation, so that it is convenient to place and arrange the packaged food in an interval arrangement and convey it, so as to prevent the food from piling up after packaging, causing the lower layer of food to be subjected to the heavy pressure of the upper layer, thereby causing extrusion deformation, and to prevent excessive pressure from causing the outer packaging to rupture. At the same time, through the interval arrangement and conveying, multiple packaged foods can be separated, which is convenient for the staff to detect the packaged food, and then the neatly arranged food packaging can make the subsequent inspection process smoother and more efficient, so that each package can be checked one by one more easily, without spending extra time and energy to sort or adjust the position of the package, and when unqualified products are found during the inspection process, the neatly arranged packages can be more easily traced back to the specific problem packages, so that timely measures can be taken to deal with them and avoid the problem from expanding.

[0008] By adopting the above technical solution, through the first spring, when the protrusion squeezes the push column to drive the swing column and the block to rotate, the swing column will also drive the pulling column to move, and then the pulling column will stretch the first spring. When the protrusion moves away from the surface of the push column, the squeezing and pushing of the push column will be released, and then the first spring will drive the pulling column, the swing column and the block to rebound and reset, so that the block re-enters the interior of the limiting groove to prevent the connecting disk, the rotating block and the blocking column from continuing to rotate.

Through the provided buffer block 52, when the food falls on the top surface of the unloading frame 42, the weight of the packaged food is The amount will press down the feeding frame 42 to drive the buffer block 52 to compress the second spring 57 and move downward, so that the position of the feeding frame 42 can be lowered to prevent the packaged food from falling from a high place and causing damage to the packaging. The conveying assembly includes a plurality of conveying holes 58, and the plurality of conveying holes 58 are respectively opened on both sides of the interior of the conveying frame 2, and every two corresponding conveying holes 58 form a group. The inner circular wall surface of each group of conveying holes 58 is movably sleeved with a transmission column 59, and a sprocket 60 is fixedly installed at one end of the transmission column 59. The outer circular wall surfaces of the two sprockets 60 are meshed and connected with a chain 61. A support frame 32 is fixedly installed on one side of the conveying frame 2, and a servo motor 4 is fixedly sleeved inside the support frame 32. The driving shaft of the servo motor 4 is fixedly installed with the sprocket 60 located on the right, and a conveyor belt 35 is wound around the outer circular wall surface of the two transmission columns 59.
[0031] Working principle: Please refer to Figure 1-Figure 10As shown, by setting the blocking column 11, after the food is packaged by the food packaging machine body 1, the packaged food will fall on the conveying frame 2 and be conveyed by the conveying component, and then the packaged food will be blocked by the blocking column 11 after reaching the position of the blocking column 11, and then the driving component is used to drive the rotating column 20, the rotating block 21 and the protrusion 22 to rotate. When the protrusion 22 rotates in a circle with the rotating block 21, the position of the protrusion 22 is constantly changed. When the position of the protrusion 22 rotates to the position of the pushing column 16, the protrusion 22 squeezes and pushes the pushing column 16. After the pushing column 16 is squeezed, the pushing column 16 pushes the swing column 14 The tail end of the swing column 14 is rotated around the positioning column 18, and then the swing column 14 will drive the block 15 to move during the rotation, so that the block 15 can be moved out of the limiting groove 13, and then the restriction of the block 15 on the connecting plate 12 can be released. At this time, when the conveying component drives the packaged food to continue to move, the packaged food will push the blocking column 11 during the movement, and then the blocking column 11 will drive the rotating block 10, the connecting column 9 and the connecting plate 12 to rotate. Since the packaged food is on the top surface of the conveying frame 2, the two blocking columns 11 are V-shaped, which can limit it in the middle of the V and block it. The blocked package will be pushed into the blocking column 11 during the rotation. The packed food is released to continue to be conveyed, and then the next packaged food will enter another V-shaped center formed by the rotation of multiple blocking columns 11 and be blocked by the blocking column 11. Because the rotating block 21 and the protruding block 22 can only make one circle each time to make the swing column 14 drive the card block 15 to move out of the limiting groove 13 to release the restriction on the connecting disk 12, so that the connecting disk 12, the connecting column 9, the rotating block 10 and the blocking column 11 can rotate freely, and then the blocking column 11 and the rotating block 10 can only rotate once. Therefore, each rotation can only allow one packaged food to pass, so as to facilitate the arrangement and conveyance of the packaged food, and prevent the food from piling up after packaging and causing the next packaged food to pass. The food in the first layer is subjected to the heavy pressure of the upper layer, thus being squeezed and deformed, and preventing the outer packaging from rupture due to excessive pressure. At the same time, multiple packaged foods can be separated by staggered arrangement and conveying, which is convenient for staff to test the packaged foods. The neatly arranged food packages can make the subsequent testing process smoother and more efficient, so that each package can be checked one by one more easily without spending extra time and energy to sort or adjust the position of the packages. Moreover, when unqualified products are found during the testing process, the neatly arranged packages can be more easily traced back to the specific problem packages, so that timely measures can be taken to deal with them and avoid the problem from expanding.
[0032] By setting the first spring 25, when the protrusion 22 squeezes the pushing column 16 to drive the swing column 14 and the block 15 to rotate, the swing column 14 will also drive the pulling column 26 to move, and then the pulling column 26 will stretch the first spring 25. When the protrusion 22 moves away from the surface of the pushing column 16, the squeezing and pushing of the pushing column 16 will be released, and then the first spring 25 will drive the pulling column 26, the swing column 14 and the block 15 to rebound and reset, so that the block 15 re-enters the interior of the limiting groove 13 to prevent the connecting disk 12, the rotating block 10 and the blocking column 11 from continuing to rotate.
[0033] By setting the pressure plate 34, when the packaged food reaches the position of the mounting frame 31, the electric push rod 33 is used, and the telescopic rod of the electric push rod 33 drives the pressure plate 34 to move downward, so that the pressure plate 34 contacts the surface of the packaged food and presses it, so as to facilitate the leakage detection of the packaged food, so as to timely deal with the loosely packaged food or the leaking packaging caused by the broken packaging bag.
[0034] By setting the infrared sensor 38, when the packaged food enters the position of the mounting rack 31, the packaged food can be detected by the infrared sensor 38. At this time, the infrared sensor 38 will transmit the signal to the PLC controller, and then the PLC controller will control the stepper motor 28 to stop to prevent the subsequent packaged food from being transported. At the same time, the PLC controller will control the electric push rod 33 to start and detect the packaged food. When the packaged food is detected, the stepper motor 28 and the conveying assembly are started at the same time to transport the next packaged food to the position of the mounting rack 31 for detection. At the same time, by using the infrared sensor 38, it is convenient to stop the stepper motor 28 in time to prevent the next packaged food from entering the mounting rack 31 while the food packaging of the mounting rack 31 is being detected.
[0035] By setting the buffer block 52, when the food falls on the top surface of the feed frame 42, the weight of the packaged food will press down the feed frame 42, driving the buffer block 52 to compress the second spring 57 and move downward, thereby lowering the position of the feed frame 42 to prevent the packaged food from falling from a high place and causing damage to the packaging.
