Description

Technical Field

[0001] The present invention relates to the technical field of feed packaging, and particularly to an automatic packaging machine for mixed feed. Background Art

[0002] Compound premixed feed refers to a uniform mixture prepared by taking any two or more of nutritional feed additives such as mineral trace elements, vitamins, and amino acids as the main components, and mixing them with other feed additives, carriers, and / or diluents in a certain proportion. The content of the nutritional feed additives can meet the basic nutritional requirements of the applicable animals at a specific physiological stage. After the compound premixed feed is prepared, it needs to be packaged by a packaging machine for subsequent transportation and sales.

[0003] An existing invention patent, such as a Chinese patent with the application patent number CN201810147436.1, discloses a new type of feed processing and packaging machine, which mainly consists of a distribution box, a feed inlet pipe, a double-screening processing hopper, a discharge pipe, a solenoid valve, an electric control box, etc. By providing double screening and processing, it can automatically screen out feeds with too large or too small particles, ensuring that the feeds to be packaged meet the requirements, effectively enhancing the automation degree of the feed processing and packaging machine, and improving the quality of the packaged feeds.

[0004] In this technical solution, during the packaging process of the feed, after quantitative packaging, manual operation is still required to seal the packaging bags, which greatly reduces the efficiency of feed packaging. At the same time, during the filling process, the feed will accumulate into a "hill" inside the packaging bag, resulting in spillage of the feed before it is fully filled, affecting the packaging progress, making the packaging less dense, occupying more space, not being convenient for transportation, and during the packaging process, it is also necessary to manually remove the packaged packaging bags, which not only has a large labor intensity but also affects the packaging efficiency. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems of low packaging efficiency and easy spillage during filling in the prior art, and to propose an automatic packaging machine for mixed feed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions: An automatic packaging machine for mixed feed, including a base, a rotating table is fixedly connected to the upper surface of the base and is rotationally connected through a bearing, and six groups of automatic packaging mechanisms are arranged inside the rotating table; The automatic packaging mechanism includes a functional hole, two control cavities, and a first installation groove formed in the rotating table. Sliding grooves are formed in the two inner side walls opposite to the functional hole. Sliders are slidably connected in the sliding grooves. A first spring is fixedly connected between the slider and the inner bottom wall of the sliding groove. The sliders are commonly fixedly connected to a U-shaped plate. The inner side walls of the U-shaped plate are rotatably connected to two baffle plates through pin shafts. An installation groove is formed in the inner side wall of one of the sliding grooves. A resistance coil is fixedly connected to the inner top wall of the installation groove. A first conductive block is fixedly connected to the lower surface of one of the sliders. The first installation groove communicates the corresponding control cavity with the functional hole. A first sliding column is hermetically slidably sleeved in the first installation groove. One end of the first sliding column located in the functional hole is fixedly connected to a heat-sealing strip. A pressure relief valve is arranged in the first installation groove. An electromagnet is fixedly connected in the control cavity. A first magnetic plate and a second magnetic plate are hermetically slidably connected in the control cavity. A plurality of second springs are fixedly connected between the first magnetic plate, the second magnetic plate and the inner wall of the control cavity. The control cavity is filled with hydraulic oil.

[0007] Furthermore, the automatic packaging mechanism further includes two second installation grooves formed in the rotating table. The second installation grooves communicate the corresponding control cavities with the functional hole. A second sliding column is hermetically slidably sleeved in the second installation groove. One end of the second sliding column located in the functional hole is fixedly connected to a hammering block. Twelve reflux pipes are fixedly connected through the rotating table. The reflux pipes communicate the corresponding first installation grooves with the control cavities. Solenoid valves are arranged in the reflux pipes.

[0008] Furthermore, a double-screening processing hopper is fixedly connected to the upper surface of the base through a bracket. A fourth bevel gear is in interference fit with the column.

[0009] Furthermore, an opening and closing mechanism for opening and closing the baffle plate is arranged in the slider. The opening and closing mechanism includes a third installation groove and a cavity formed in the slider. The third installation groove communicates with the cavity. A connecting block is hermetically slidably sleeved in the third installation groove. One end of the connecting block located in the functional hole is fixedly connected to the lower surface of the corresponding baffle plate. A sliding plate is hermetically slidably connected in the cavity. An electric push rod is fixedly connected to the inner side wall of the cavity. The output end of the electric push rod is fixedly connected to the sliding plate. A second conductive block is fixedly connected to the inner side wall of the sliding groove below the installation groove. Hydraulic oil is filled between the sliding plate and the connecting block.

[0010] Further, six driving mechanisms for driving the rotating table to rotate are arranged inside the rotating table. Each driving mechanism includes a driving groove formed inside the rotating table. The driving groove communicates with the corresponding sliding groove. A rack is fixedly connected to the side wall of the slider close to the sliding groove. The inner side wall of the driving groove is rotatably connected to a rotating shaft through a bearing. The rotating shaft is rotatably connected to a gear through a one-way bearing. The gear meshes with the rack. A first bevel gear is in interference fit with the rotating shaft. The rotating table is rotatably connected through a bearing to a driven shaft. One end of the driven shaft penetrates and extends into the driving groove and is in interference fit with a second bevel gear, and the other end penetrates and extends outside the rotating table and is in interference fit with a third bevel gear. The second bevel gear meshes with the first bevel gear, and the third bevel gear meshes with a fourth bevel gear.

[0011] Further, the hammering block is made of rubber.

[0012] Further, six through holes are formed in the bottom wall of the rotating table. The rack penetrates through the bottom wall of the rotating table through the corresponding through holes.

[0013] Further, the cross-sectional area of the cavity is larger than the cross-sectional area of the third installation groove.

[0014] The present invention has the following advantages: 1. Place the packaging bag on the clip board in the functional hole, and perform filling through the double-screening processing hopper. As the feed is continuously filled, the weight continuously increases, and the packaging bag drives the clip board to descend until it is filled to the specified amount. The change in the contact position between the first conductive block and the resistance coil changes the resistance in the circuit, thereby changing the magnetic force generated by the electromagnet until the magnetic force is sufficient to overcome the critical value of the pressure relief valve, so that the two heat-sealing strips slide out to heat-seal the packaging bag. Thus, the packaging machine can automatically perform quantitative filling and then sealing, avoiding the need for manual sealing later, and greatly improving the packaging efficiency. 2. During the filling process, the downward sliding of the first conductive block continuously contacts and separates from the resistance coil, so that the electromagnet is alternately powered on and off, and thus the second magnetic plate continuously moves up and down reciprocally. As a result, the hammering block continuously hammers the packaging bag during the filling process, thereby leveling the feed in the packaging bag and avoiding the formation of a "hill" during the filling process, which may cause feed spillage. 3. After the previous packaging bag is filled, when the first conductive block contacts the second conductive block, the baffle in the functional hole that has been filled can be opened, so that the filled packaging bag drops, and the packaged packaging bag automatically drops for collection. This avoids the process of manually unloading the packaged packaging bag, greatly reducing the labor intensity and improving the efficiency. 4. After the packaging bag drops, during the process of the slider returning to its position by the elastic force of the first spring, through the meshing between the rack and the gear and the four bevel gears, the rotating table automatically rotates, turning the next packaging bag to be filled under the double-screening processing hopper and waiting to be filled. The staff only needs to continuously place empty packaging bags into the empty functional holes, making the packaging machine more automated; 5. From the completion of filling to the dropping of the packaging bag, the heat-sealing strip always keeps sealing the packaging bag, thus making the sealing effect better and avoiding the situation of opening after sealing.

Detailed Embodiments

[0017] Refer to Figures 1-7, an automatic packaging machine for mixed feed, including a base 1. A column 2 is fixedly connected to the upper surface of the base 1, and a rotating table 3 is rotatably connected through a bearing. Six groups of automatic packaging mechanisms are arranged in the rotating table 3; The automatic packaging mechanism includes a function hole 4, two control cavities 13, and a first installation groove 15 opened in the rotating table 3. In the control cavity 13, the space between the first magnetic plate 19 and the second magnetic plate 20 is communicated with the outside, so as to ensure the free up and down movement of the first magnetic plate 19 and the second magnetic plate 20. Sliding grooves 5 are opened on the two inner side walls opposite to the function hole 4. A slider 6 is slidably connected in the sliding groove 5. A first spring 7 is fixedly connected between the slider 6 and the bottom wall of the sliding groove 5. The sliders 6 are commonly fixedly connected to a return plate 8. The cross-section of the return plate 8 is in the shape of a Chinese character "hui". Two baffles 9 are rotatably connected to the inner side wall of the return plate 8 through a pin shaft. In the initial state, the baffles 9 block the hole of the return plate 8, so that the packaging bag can be placed above it. An installation groove 10 is opened on the inner side wall of one of the sliding grooves 5. A resistance coil 11 is fixedly connected to the top wall of the installation groove 10. A first conductive block 12 is fixedly connected to the lower surface of one of the sliders 6. The first installation groove 15 communicates the corresponding control cavity 13 with the function hole 4. A first sliding column 16 is hermetically slidably sleeved in the first installation groove 15. One end of the first sliding column 16 located in the function hole 4 is fixedly connected to a heat-sealing strip 17. The temperature of the heat-sealing strip 17 is relatively high. When the two heat-sealing strips 17 are combined, the opening of the packaging bag can be heat-sealed. A pressure relief valve 18 is arranged in the first installation groove 15. The pressure relief valve 18 can be opened after the pressure reaches a certain value. An electromagnet 14 is fixedly connected in the control cavity 13. A first magnetic plate 19 and a second magnetic plate 20 are hermetically slidably connected in the control cavity 13. After the electromagnet 14 is energized, a magnetic repulsive force can be generated on the first magnetic plate 19 and the second magnetic plate 20. A number of second springs 21 are fixedly connected between the first magnetic plate 19, the second magnetic plate 20 and the inner wall of the control cavity 13. The control cavity 13 is filled with hydraulic oil. The space between the first magnetic plate 19 and the first sliding column 16 is filled with hydraulic oil. The space between the second magnetic plate 20 and the second sliding column 25 is filled with hydraulic oil. As Figure 7As shown in the figure, the first conductive block 12 is connected to the positive electrode of the power supply. After the resistance coil 11 is connected to the electromagnet 14, it is then connected to the negative electrode of the power supply. During the filling process, as the double-screening processing hopper 44 fills the packaging bag, the weight of the feed in the packaging bag continuously increases, driving the return plate 8 and the slider 6 to descend. During the descent of the slider 6, the first conductive block 12 is driven to descend. The first conductive block 12 continuously contacts and separates from the resistance coil 11. As the first conductive block 12 slides down, each time it contacts the resistance coil 11, the resistance connected to the circuit continuously decreases, so that the resistance connected to the electromagnet 14 continuously decreases. Until after filling a certain amount, the double-screening processing hopper 44 stops filling. At this time, the contact position between the first conductive block 12 and the resistance coil 11 makes the resistance connected to the electromagnet 14 extremely small, so that the magnetic force of the electromagnet 14 is relatively large, generating a relatively large magnetic repulsive force on the first magnetic plate 19. At this time, the pressure reaches the critical value of the pressure relief valve 18, causing the pressure relief valve 18 to open. The first magnetic plate 19 presses the hydraulic oil into the first installation groove 15, so that the first sliding column 16 drives the heat-sealing strip 17 to seal the packaging bag, so that after the quantitative filling is completed, the packaging bag can be automatically sealed, avoiding subsequent sealing operations, greatly improving the packaging efficiency, and at the same time improving the automation degree of the machine.

[0018] The automatic packaging mechanism further includes two second installation grooves 24 opened in the rotating table 3. The second installation grooves 24 communicate the corresponding control cavities 13 with the function holes 4. A second sliding column 25 is hermetically and slidably sleeved in the second installation groove 24. One end of the second sliding column 25 located in the function hole 4 is fixedly connected with a hammering block 26. The rotating table 3 is fixedly connected through twelve return pipes 22. The return pipes 22 communicate the corresponding first installation grooves 15 with the control cavities 13. A solenoid valve 23 is arranged in the return pipe 22. The solenoid valve 23 is a normally closed solenoid valve and is opened when powered on, as Figure 2 shown, the resistance coil 11 is spiral, and the distance between two spirals is greater than the thickness of the first conductive block 12. Therefore, as the filling progresses and the weight in the packaging bag increases, driving the slider 6 to slide down, the first conductive block 12 continuously contacts and then separates from the resistance coil 11, so that the electromagnet 14 is continuously powered on and off. After being powered on, a magnetic repulsive force is generated on the second magnetic plate 20. After being powered off, under the elastic force of the second spring 21, the second magnetic plate 20 resets. Therefore, during the filling process, the second magnetic plate 20 continuously moves up and down reciprocally, so that the hammering block 26 continuously moves reciprocally and continuously hammers the packaging bag, thereby leveling the feed in the packaging bag, avoiding the formation of a "small mountain" during the filling process, resulting in feed spillage, and at the same time ensuring that the packaged feed is denser and reducing the occupied space; It is worth mentioning that as the first conductive block 12 slides down, the contact position between it and the resistance coil 11 changes, reducing the resistance in the circuit and continuously increasing the magnetic force of the electromagnet 14. As the filling amount increases, the hammering force of the hammering block 26 continuously increases, so that the feed in the packaging bag can be better evenly distributed.

[0019] A double-screening processing hopper 44 is fixedly connected to the upper surface of the base 1 through a bracket. The double-screening processing hopper 44 can screen the feed and then quantitatively fill it, which is the prior art and will not be elaborated here. The fourth bevel gear 43 is in interference fit with the column 2.

[0020] An opening and closing mechanism for opening and closing the baffle 9 is arranged in the slider 6. The opening and closing mechanism includes a third installation groove 27 and a cavity 29 opened in the slider 6. As Figure 3 shown, the cavity 29 communicates with the outside, ensuring that the side of the sliding plate 30 away from the hydraulic oil is in an open state, so that the sliding plate 30 can freely move left and right. The third installation groove 27 communicates with the cavity 29. A connecting block 28 is hermetically and slidably sleeved in the third installation groove 27. One end of the connecting block 28 located in the function hole 4 is fixedly connected to the lower surface of the corresponding baffle 9. A sliding plate 30 is hermetically and slidably connected in the cavity 29. An electric push rod 31 is fixedly connected to the inner side wall of the cavity 29. When the electric push rod 31 is powered off, it is in the extended state and retracts when powered on. The output end of the electric push rod 31 is fixedly connected to the sliding plate 30. A second conductive block 32 is fixedly connected to the inner side wall of the sliding groove 5 below the installation groove 10. Hydraulic oil is filled between the sliding plate 30 and the connecting block 28. As Figure 7 shown, after the second conductive block 32 is connected to the electric push rod 31 and the electric push rod 31 in the previous function hole 4 of the function hole 4 through a wire and then connected to the negative pole of the power supply, when the first conductive block 12 contacts the second conductive block 32 after the feed in the function hole 4 is filled, the electric push rod 31 in the previous function hole where the filling is completed is powered on and retracts, and at the same time, the solenoid valve 23 is powered on and opened. After the solenoid valve 23 is opened, under the elastic force of the second spring 21, the first magnetic plate 19 resets, and the hydraulic oil flows back through the return pipe 22, so that the two heat-sealing strips 17 move away from the packaging bag to complete the sealing. At the same time, when the electric push rod 31 retracts, the sliding plate 30 makes the connecting block 28 slide into the third installation groove 27 through the hydraulic oil, so that the baffle 9 rotates 90° to open, so that the previously packaged packaging bag falls for collection, completing automatic feeding.

[0021] There are six groups of driving mechanisms for driving the rotary table 3 to rotate inside the rotary table 3. The driving mechanism includes a driving groove 33 opened inside the rotary table 3. The driving groove 33 communicates with the corresponding sliding groove 5. A rack 37 is fixedly connected to the side wall of the slider 6 close to the sliding groove 5. The inner side wall of the driving groove 33 is rotatably connected to a rotating shaft 35 through a bearing. The rotating shaft 35 is rotatably connected to a gear 36 through a one-way bearing. When the rack 37 moves downward to drive the gear 36 to rotate, the gear 36 will not drive the rotating shaft 35 to rotate at this time. Only when the rack 37 moves upward to drive the gear 36 to rotate, the gear 36 will drive the rotating shaft 35 to rotate. The gear 36 meshes with the rack 37. A first bevel gear 38 is in interference fit with the rotating shaft 35. The rotary table 3 is rotatably connected through a bearing to a driven shaft 40. One end of the driven shaft 40 penetrates and extends into the driving groove 33 and is in interference fit with a second bevel gear 39. The other end penetrates and extends outside the rotary table 3 and is in interference fit with a third bevel gear 42. The second bevel gear 39 meshes with the first bevel gear 38. The third bevel gear 42 meshes with a fourth bevel gear 43. When the slider 6 is at the highest point and the lowest point, the rack 37 does not mesh with the gear 36, thus avoiding interference. After the packaging bag falls, when the slider 6 slides upward under the elastic force of the first spring 7, through the meshing of the rack 37 and the gear 36, the gear 36 drives the first bevel gear 38 to rotate through the rotating shaft 35. Then, through the meshing of the second bevel gear 39 and the first bevel gear 38 and the meshing of the third bevel gear 42 and the fourth bevel gear 43, the entire rotary table 3 rotates, so as to rotate the next packaging bag to be filled under the double-screening processing hopper 44.

[0022] The hammer block 26 is made of rubber. The hammer block 26 made of rubber is softer in texture, avoiding damaging the outer surface of the packaging bag during the hammering process, thus avoiding the occurrence of holes and feed leakage during subsequent transportation.

[0023] Six through holes 41 are opened on the bottom wall of the rotary table 3. The rack 37 penetrates through the bottom wall of the rotary table 3 through the corresponding through holes 41. Through the setting of the through holes 41, when the slider 6 drives the rack 37 to move downward, the rack 37 can pass through the through holes 41 without being interfered by the bottom wall of the rotary table 3.

[0024] The cross-sectional area of the cavity 29 is larger than the cross-sectional area of the third installation groove 27, so that a small movement of the sliding plate 30 can drive the connecting block 28 to mostly slide into the third installation groove 27 through the hydraulic oil, thereby rotating the baffle 9 by 90°, so that the packaging bag can fall.

[0025] In the present invention, empty packaging bags are continuously put into the functional holes 4, and filled through the double screening processing bucket 44. During the filling, the feed in the packaging bag is continuously increased, so that the packaging bag drives the circular plate 8 to slide down, thereby causing the slider 6 to slide down. While the slider 6 slides down, it drives the first conductive block 12 to continuously slide down. The first conductive block 12 continuously contacts and separates from the resistance coil 11, thereby causing the electromagnet 14 to be continuously powered on and off. After being powered on, the electromagnet 14 generates a magnetic repulsive force on the second magnetic plate 20. After being powered off, the second magnetic plate 20 is reset under the elastic force of the second spring 21, thereby causing the second magnetic plate 20 to continuously reciprocate up and down during the filling process. The second magnetic plate 20 causes the second slide column 25 to slide back and forth through the hydraulic oil. The second slide column 25 drives the hammer block 26 to continuously reciprocate, and continuously hammers the packaging bag, thereby vibrating the feed in the packaging bag. As the filling proceeds, the first conductive block 12 continues to descend along with the slider 6, and the first conductive block 12 continuously contacts and separates from the resistance coil 11. As the first conductive block 12 slides down, each time it contacts the resistance coil 11, the resistance of the connected circuit is continuously reduced, so that the resistance of the connected electromagnet 14 is continuously reduced, until a certain amount is filled, and the double screening processing bucket 44 stops filling. At this time, the contact position of the first conductive block 12 and the resistance coil 11 makes the resistance of the connected electromagnet 14 extremely small, so that the magnetic force of the electromagnet 14 is relatively large, and a large magnetic repulsion force is generated on the first magnetic plate 19. At this time, the magnetic repulsion force acts on the hydraulic oil and then on the pressure relief valve 18, reaching the critical value of the pressure relief valve 18, so that the pressure relief valve 18 is opened, and the first magnetic plate 19 presses the hydraulic oil into the first mounting groove 15, so that the first slide column 16 drives the heat sealing strip 17 to seal the packaging bag; At the same time, the first conductive block 12 contacts the second conductive block 32, so that the electric push rod 31 and the solenoid valve 23 at the function hole 4 that has been filled are energized. After the solenoid valve 23 is opened, under the elastic force of the second spring 21, the hydraulic oil in the first installation groove 15 flows back into the control chamber 13 through the return pipe 22, so that the first slide column 16 drives the two heat sealing strips 17 to separate and complete the sealing. At the same time, the electric push rod 31 is energized and retracted, so that the two sliding plates 30 slide and the hydraulic oil in the corresponding third installation groove 27 is drawn into the cavity 29, so that the connecting block 28 slides into the third installation groove 27, so that the connecting block 28 drives the baffle 9 to rotate, so that the last packaged packaging bag falls down for collection; After the previous packaging bag drops, under the elastic force of the first spring 7, the slider 6 at the previous functional hole 4 slides upward and resets, driving the rack 37 to move upward, so that the gear 36 engaged with the rack 37 rotates. Due to the setting of the one-way bearing, at this time, the gear 36 can drive the rotating shaft 35 to rotate, so that the first bevel gear 38 in interference fit with the rotating shaft 35 rotates. The first bevel gear 38 drives the second bevel gear 39 engaged with it to rotate. The second bevel gear 39 drives the third bevel gear 42 to rotate through the driven shaft 40. Through the rotation of the third bevel gear 42 and the engagement with the fourth bevel gear 43, the entire rotating table 3 rotates, so as to rotate the packaging bag that has been filled at this time away from under the double-screening processing hopper 44, and at the same time rotate the empty packaging bag to under the double-screening processing hopper 44 to wait for filling. When waiting for the empty packaging bag to be filled and sealed, the previous packaged packaging bag drops, and so on in a cycle; While the slider 6 slides upward, the first conductive block 12 is separated from the second conductive block 32, so that the electric push rod 31 is powered off and extends. Through the sliding plate 30, the connecting block 28 slides, so that the baffle 9 returns to its position. At this time, a packaging bag can be continuously placed into the functional hole 4.
