Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, specifically to conveying equipment, a method for packaging bio-fermented feed, and a process for processing fermented feed. Background Technology

[0002] The packaging system for granular or powder materials packaged in woven bags mainly consists of a quantitative filling device, a conveying device, and a bag sealing machine. The main steps are to place the woven bag at the feeding port of the quantitative filling device, which has a built-in weight sensor to accurately feed and fill the bag. After that, the unsealed woven bag is moved by the conveying device to the bag sealing machine for automatic sealing. Finally, the woven bag is held onto the tray by a robotic arm.

[0003] Chinese patent application CN213705932U discloses an automatic feed packaging machine, which realizes quantitative packaging and transportation of feed through a filling machine, conveyor belt and sealing machine. However, it has certain shortcomings: feed is divided into various types, and different feed preservation methods are insufficient. Among them, biological fermentation feed is preferred to be preserved by sealing and single-venting, which is conducive to the formation of an anaerobic environment and ensures the quality of feed. Therefore, double-layer composite woven bags are often used for packaging. Existing bagging equipment only uses sewing to seal and lacks a fixing method for the inner bag of composite woven bags. When sealing by sewing alone, the sealing performance is insufficient, which can easily lead to the deterioration of fermented feed and poor packaging effect.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0023] A fermented feed processing technology uses the conveying equipment described above.

[0024] Compared with the prior art, the present invention provides a conveying device, a method for packaging bio-fermented feed, and a processing technology for fermented feed, which have the following beneficial effects:

[0025] 1. This type of conveying equipment, biological fermented feed packaging method, and fermented feed processing technology, by setting a movable feeding port on the filling machine, and setting an inner bag clamping component and an inner bag welding component at the feeding port, and setting an outer bag holding component between the filling machine and the sealing machine, first fixes the inner bag of the woven bag during filling, and then welds and seals the inner bag of the woven bag after filling, and then keeps the outer bag of the woven bag closed until it enters the sealing machine. Thus, the double-layer composite woven bag is used to package and convey feed that requires sealing. Compared with manual sealing, it saves time and labor, is more efficient, and improves the sealing performance compared with common bagging equipment, which is conducive to product preservation and improves product quality.

[0026] 2. This conveying equipment, bio-fermented feed packaging method, and fermented feed processing technology, through the setting of an outer bag retaining component, uses the snap ring on the strip rod to fix the bag opening, preventing the outer bag from moving during filling, making it more stable and eliminating the need for manual stabilization by the operator. After filling is completed, the two strip rods move with the woven bag and merge, closing the bag opening. This facilitates the outer bag entering the sealing machine with a closed opening, making subsequent sewing work easier and improving the accuracy of sewing.

[0027] 3. This type of conveying equipment, biological fermented feed packaging method, and fermented feed processing technology, by setting up a pressing component, facilitates the use of a base plate to press the top of the inner bag in the outer bag before closing the outer bag opening, causing the top of the inner bag to retract inward, avoiding the sewing position of the outer bag, thereby preventing the inner bag from being punctured when the outer bag is sewn, and further ensuring the sealing of the inner bag.

[0039] 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.

[0040] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a conveying device, a biological fermented feed packaging method, and a fermented feed processing technology.

[0041] Please see Figures 1-2 The conveying equipment includes a filling machine 1, a conveyor 2 and a sealing machine 3. The filling machine 1 is provided with a feeding hopper 4 at the bottom, and also includes a feeding port 5, an inner bag clamping assembly 6, an inner bag welding assembly 7 and an outer bag holding assembly 8.

[0042] The discharge port 5 is movably inserted into the bottom of the discharge hopper 4, and the movable discharge hopper 4 is used for discharging material.

[0043] The inner bag clamping assembly 6 is installed on the hopper 4 and located on the side of the discharge port 5. The inner bag clamping assembly 6 is connected to the discharge port 5 in a transmission manner. The inner bag clamping assembly 6 is used to fix the inner bag, straighten the inner bag opening, and drive the discharge port 5.

[0044] The inner bag welding assembly 7 is installed on the hopper 4 and located on the side of the discharge port 5. The inner bag welding assembly 7 is used to seal the inner bag.

[0045] The outer bag retaining assembly 8 is mounted on the transmission mechanism, and the outer bag retaining assembly 8 is used to fix the outer bag and close the outer bag opening;

[0046] Before filling, the outer bag holding component 8 fixes the edge of the woven bag, and the inner bag clamping component 6 fixes the edge of the woven bag after it is rotated.

[0047] After the filling process, the inner bag clamping component 6 operates, straightening the inner bag opening while driving the discharge port 5 to detach from the inner bag. When the inner bag welding component 7 operates, it heat-presses and seals the inner bag opening.

[0048] After the inner bag is sealed, the inner bag clamping component 6 operates and releases the inner bag. The conveyor 2 and the outer bag holding component 8 operate, forcing the outer bag opening to close while moving into the sealing machine 3.

[0049] The principles of filling machine 1, conveyor 2 and sealing machine 3 are the same as those of the prior art. The feeding port 5 is set to a square tube shape. The number of inner bag clamping components 6 is set to two and symmetrically distributed on the left and right sides of the feeding port 5. The number of inner bag welding components 7 is also set to two and symmetrically distributed on the front and rear sides of the feeding port 5. The woven bags mentioned in this embodiment are all double-layer composite plastic woven bags in the prior art.

[0050] During use, before filling, the outer bag opening of the woven bag is first fixed by the outer bag holding component 8. Then, the inner bag opening is placed over the feed inlet 5, with the inner bag opening higher than the outer bag opening. The two inner bag clamping components 6 are then activated, clamping and fixing the inner bag opening. The filling machine 1 is then started to achieve quantitative filling. After filling, the two inner bag clamping components 6 are activated again, forcing the feed inlet 5 to move upwards and detach from the inner bag. Pull the inner bag opening to straighten it. Then, start the inner bag welding assembly 7. When the two inner bag welding assemblies 7 are running, they weld the inner bag opening to seal the inner bag. Then, start the inner bag clamping assembly 6 again to release the inner bag. The released inner bag falls into the outer bag under its own weight and stands on the conveyor 2. Then, the conveyor 2 and the outer bag holding assembly 8 are running. When the conveyor 2 is running, it drives the woven bag to move towards the sealing machine 3. When the outer bag holding assembly 8 is running, it moves with the woven bag and closes the outer bag opening at the same time.

[0051] By setting a movable feeding port 5 on the filling machine 1, and setting an inner bag clamping component 6 and an inner bag welding component 7 at the feeding port 5, and setting an outer bag holding component 8 between the filling machine 1 and the sealing machine 3, the inner bag of the woven bag is first fixed during filling, and then welded and sealed after filling. Then the outer bag of the woven bag is kept closed until it enters the sealing machine 3. Thus, the double-layer composite woven bag is used to package and transport feed that requires sealing. Compared with manual sealing, it saves time and effort and is more efficient. Compared with common bagging equipment, it improves the sealing performance, which is conducive to product preservation and improves product quality.

[0052] Further, see Figures 3-6 The inner bag clamping assembly 6 includes a vertically distributed first slide rail 61 and a second slide rail 62. The second slide rail 62 is fixedly connected to the hopper 4 via a bracket. A second slider 63 is slidably connected inside the second slide rail 62 and is fixedly connected to the first slide rail 61. Two first sliders 64 are slidably connected inside the first slide rail 61. A clamping plate 65 is fixed to the bottom of each of the two first sliders 64. A first bidirectional screw 66 is also provided inside the first slide rail 61. The first bidirectional screw 66 passes through the two first sliders 64 and is threaded onto the two first sliders 64. The connection is as follows: both ends of the first bidirectional screw 66 are rotatably connected to the first slide rail 61; the first slide rail 61 is fixedly connected to the end of the first motor 67; the output shaft of the first motor 67 is fixedly connected to the first bidirectional screw 66; a fixed pulley 68 is movably installed on the end of the second slide rail 62 near the discharge port 5; a first cylinder 69 is fixedly connected to the top of the second slide rail 62; the output end of the first cylinder 69 is fixedly connected to the second slider 63; a pull rope 60 is fixedly attached to one side of the second slider 63; one end of the pull rope 60 passes around the fixed pulley 68 and is fixedly connected to the side wall of the discharge port 5.

[0053] The bracket is welded to the second track and the hopper 4 at both ends, the second slide rail 62 and the first slide rail 61 are both set horizontally, the surface of the first bidirectional screw 66 is provided with two sets of symmetrically distributed threads with opposite directions of rotation, the two first sliders 64 are matched with the two sets of threads respectively, the fixed pulley 68 is rotatably connected to the second slide rail 62 through the central shaft, and the first cylinder 69 is set parallel to the second slide rail 62.

[0054] In use, first, place the inner bag of the woven bag onto the feed opening 5. Since the opening of the inner bag is larger than the feed opening 5, then place the excess portion at both ends of the bag opening between the two clamping plates 65. Next, start the first motor 67. The first motor 67, once running, drives the first bidirectional screw 66 to rotate. As the first bidirectional screw 66 rotates, it drives the two first sliders 64 to move simultaneously towards the center of the first bidirectional screw 66. The movement of the two first sliders 64 drives the two clamping plates 65 to move, clamping and fixing the opening of the inner bag. The filling machine 1 fills the inner bag with feed. After filling, the first cylinder 69 is started. The first cylinder 69 extends and drives the second slider 63 to slide. When the second slider 63 moves, it drives the pull rope 60 to move. The other end of the pull rope 60 pulls the feed outlet 5 upward, so that the feed outlet 5 is separated from the inner bag. At the same time, when the second slider 63 slides, it drives the first slide rail 61 and the clamping plate 65 at the bottom of the first slider 64 to move. At this time, the two sets of clamping plates 65 clamping the inner bag opening move in opposite directions to straighten the inner bag opening.

[0055] By setting the inner bag clamping component 6, it is beneficial to fix the inner bag during filling without manual control, effectively preventing the inner bag from loosening and falling off, thereby preventing feed spillage. In addition, the inner bag clamping component 6 straightens the opening of the inner bag after filling, so as to facilitate subsequent sealing of the inner bag.

[0056] Further, see Figures 3-6 The inner bag welding assembly 7 includes a movable frame 71 and a second cylinder 72 above the movable frame 71. One end of the movable frame 71 is hinged to the feeding hopper 4, and the other end of the movable frame 71 is fixedly connected to a clamping strip 73. An electric heating plate 74 is fixedly connected to the surface of the clamping strip 73. One end of the second cylinder 72 is hinged to the feeding hopper 4, and the other end of the second cylinder 72 is hinged to the movable frame 71.

[0057] Among them, the electric heating plate 74 is set as a horizontal strip, and the length of the electric heating plate 74 is greater than the width of the inner bag opening. The electric heating plate 74 generates heat itself after being powered on, which is existing technology and will not be described in detail.

[0058] When in use, after the inner bag opening is taut, two second cylinders 72 are activated simultaneously. The second cylinders 72 extend and push the movable frame 71, causing the top of the movable frame 71 to rotate, which in turn drives the clamping strip 73 at the bottom to move. Finally, the two clamping strips 73 merge together, clamping the taut bag opening in the middle. At the same time, the heat generated by the electric heating plate 74 melts the inner bag opening, sealing the bag opening. Finally, the second cylinder 72 is controlled to retract, causing the two clamping strips 73 to return to their original position, thus completing the sealing of the inner bag.

[0059] By setting up the inner bag welding assembly 7, the taut inner bag opening is clamped by the clamping strip 73, and the bag opening is welded by the heat generated by the electric heating plate 74, which is conducive to sealing the inner bag. This sealing method has better sealing performance, which is conducive to the preservation of feed in the inner bag and ensures the quality of feed.

[0060] Further, see Figures 7-10 The outer bag holding assembly 8 includes a crossbeam 801 located above the conveyor 2. A third slide rail 802 is fixedly connected to the side of the crossbeam 801 near the discharge port 5. Two third sliders 803 are slidably connected to the inner side of the third slide rail 802. A strip rod 804 is fixedly connected to each of the two third sliders 803. A bending spring 805 is provided on the strip rod 804, and the top end of the bending spring 805 is fixedly connected to the strip rod 804. A second bidirectional screw 806 is provided inside the third slide rail 802. The second bidirectional screw 806 passes through the two third sliders 803 and is threadedly connected to the two third sliders 803. Both ends of the second bidirectional screw 806 are rotatably connected to the third slide rail 802. A first base shaft 807 is provided at the end of the crossbeam 801. The first base shaft 807 is mounted on the crossbeam 801 through a first bearing seat 808. A second driven gear 809 and a first bevel gear are fixed to both ends of the first base shaft 807, respectively. The wheel 810, the end of the second bidirectional screw 806 is fixedly connected to a second bevel gear 811, the second bevel gear 811 meshes with the first bevel gear 810, the side of the crossbeam 801 away from the feed port 5 is fixedly connected to a third cylinder 812, the output end of the third cylinder 812 is fixedly connected to a double-sided rack 813, the double-sided rack 813 is laterally slidably connected to the crossbeam 801, the second driven gear 809 is located on the sliding path of the double-sided rack 813, the... The outer bag holding assembly 8 also includes a horizontal slide 814 and a vertical slide 815. The horizontal slide 814 is located between the conveyor 2 and the sealing machine 3. The horizontal slide 814 is fixedly connected to the edge of the conveyor 2 via a support leg 816. A horizontal slide block 817 is provided on the horizontal slide 814. The vertical slide 815 is fixed on the horizontal slide block 817. A vertical slide block 818 is provided on the vertical slide block. The vertical slide block 818 is fixedly connected to the end of the crossbeam 801.

[0061] Each bar 804 is preferably provided with two bent springs 805, and the positions of the bent springs 805 on the two bars 804 are staggered. The surface of the second bidirectional screw 806 is provided with two sets of symmetrically distributed threads with opposite directions of rotation. The two third sliders 803 are respectively matched with the two sets of threads. The transverse slide 814 and the vertical slide 815 are both set as electric slides. The two ends of the support leg 816 are respectively welded to the edge of the transmission machine and the transverse slide 814. In the initial state, the double-sided rack 813 is not engaged with the second driven gear 809. The two bars 804 are located below the hopper 4.

[0062] During use, before filling, the outer edge of the woven bag is inserted into the bending springs 805 on the two strip rods 804. The elasticity of the bending springs 805 clamps the edge of the outer bag, so that the bottom edge of the outer bag is just placed on the surface of the conveyor 2. After the inner bag is filled, the sealed inner bag falls into the outer bag. Under the weight of the feed, the woven bag stands upright on the conveyor 2. At this time, the conveyor 2 and the transverse slide 814 are started. When the conveyor 2 is running, it drives the woven bag to move towards the sealing machine 3. When the transverse slide 814 is running, it drives the transverse slide block 817 to move towards the sealing machine 3. The transverse slide block 817 drives the vertical slide block 815, the crossbeam 801, and the strip rods 804 on the crossbeam 801 to move with the woven bag. Then, the third cylinder 812 is started, and the second cylinder 72 extends to drive the double-sided rack 813 to slide. The double-sided rack 813 slides a certain distance. After the distance is reached, it meshes with the second driven gear 809 and drives the second driven gear 809 to rotate. When the second driven gear 809 rotates, it drives the first base shaft 807 and the first bevel gear 810 to rotate. When the first bevel gear 810 rotates, it drives the second bevel gear 811 to rotate. When the second bevel gear 811 rotates, it drives the second double-direction screw 806 to rotate. When the second double-direction screw 806 rotates, it drives the two strip rods 804 holding the bag opening of the outer bag to move closer to each other until they are in contact, thereby making the bag opening of the outer bag closed. When the woven bag moves into the sealing machine 3, the vertical slide table 815 operates, driving the vertical slide block 818 to move upward. When the vertical slide block 818 moves upward, it drives the crossbeam 801 and the strip rods 804 on the crossbeam 801 to move upward. When the strip rods 804 move upward, the retaining spring disengages from the outer bag, so that the outer bag is in a closed state for subsequent sewing work.

[0063] By setting the outer bag retaining component 8, the snap ring on the strip rod 804 can fix the bag opening, preventing the outer bag from moving during filling, making it more stable and eliminating the need for manual stabilization by the operator. After filling is completed, the two strip rods 804 move with the woven bag and merge to close the bag opening, which helps the outer bag enter the sealing machine 3 with the bag opening closed, facilitating subsequent sewing work and improving the accuracy of sewing. The vertical slide table 815 can also adjust the initial height of the crossbeam 801 and the strip rod 804, thereby adapting to woven bags of different heights and improving applicability.

[0064] Further, see Figures 7-10 A pressing assembly 9 is provided on the crossbeam 801. The pressing assembly 9 includes a fixed seat 901, a second base shaft 902, and a mounting bracket 903. The fixed seat 901 is fixed to the top surface of the third slide rail 802. A base plate 904 is mounted on the mounting bracket 903. A rotating shaft 905 is fixed to the bottom of the mounting bracket 903. The rotating shaft 905 is rotatably connected to the fixed seat 901. A torsion spring 906 is installed at the connection between the rotating shaft 905 and the fixed seat 901. A fourth bevel gear 907 is fixed to one end of the rotating shaft 905. The second base shaft 902 is mounted on the top of the crossbeam 801 through a second bearing seat 912. A third bevel gear 908 and a first driven gear 909 are fixedly connected to both ends of the second base shaft 902, respectively. The third bevel gear 908 meshes with the fourth bevel gear 907. The first driven gear 909 is located on the sliding path of the double-sided rack 813.

[0065] The substrate 904 is located on the side of the mounting frame 903 near the hopper 4. In the initial state, both the mounting frame 903 and the substrate 904 are vertical. The substrate 904 is preferably set as a square or oval plate smaller than the opening of the outer bag.

[0066] In use, when the third cylinder 812 is activated, the third cylinder 812 drives the double-sided rack 813 to slide. The double-sided rack 813 first contacts the first driven gear 909 and drives the first driven gear 909 to rotate. When the first driven gear 909 rotates, it drives the second base shaft 902 and the third bevel gear 908 to rotate. When the third bevel gear 908 rotates, it drives the fourth bevel gear 907 to rotate. When the fourth bevel gear 907 rotates, it drives the rotating shaft 905 to rotate. The rotating shaft 905 drives the mounting bracket 903 and the base plate 904 on the mounting bracket 903 to rotate, and causes the torsion spring 906 to deform. After the base plate 904 rotates, it just enters the inside of the outer bag and presses the top of the inner bag. Then the double-sided rack 813 disengages from the first driven gear 909. Under the elastic force of the torsion spring 906, the mounting bracket 903 and the base plate 904 rotate and reset.

[0067] By setting up the pressing component 9, it is beneficial to press the top of the inner bag in the outer bag with the base plate 904 before closing the outer bag opening, so that the top of the inner bag retracts inward and avoids the sewing position of the outer bag, thereby avoiding the situation of puncturing the inner bag when the outer bag is sewn, and further ensuring the sealing of the inner bag.

[0068] Further, see Figure 9 A plurality of insert rods 910 are fixed on one side of the substrate 904. The insert rods 910 are movably inserted into the mounting bracket 903. A spring 911 is sleeved on the outside of the insert rods 910. The two ends of the spring 911 are fixedly connected to the mounting bracket 903 and the substrate 904, respectively.

[0069] The insert rod 910 and spring 911 are both set in multiple groups. When in use, the elasticity of the spring 911 allows the base plate 904 to adapt to the top height of different inner bags when pressed, thus improving applicability.

[0070] Working principle: During use, before filling, the outer edge of the woven bag is inserted into the bending springs 805 on the two strip rods 804. The elasticity of the bending springs 805 is used to clamp the outer edge of the bag. At this time, the bottom edge of the outer bag is just placed on the surface of the conveyor 2. Then, the middle of the inner bag is placed on the feed inlet 5. Since the opening of the inner bag is larger than the feed inlet 5, the excess part at both ends of the bag opening is placed between the two clamping plates 65. Then, the first motor 67 is started. After the first motor 67 runs, it drives the first bidirectional screw 66 to rotate. When the first bidirectional screw 66 rotates, it drives the two first sliders 64 to move towards the middle of the first bidirectional screw 66 at the same time. When the two first sliders 64 move, they drive the two clamping plates 65 to move, clamping and fixing the opening of the inner bag. Then, the filling machine 1 fills the inner bag with feed.

[0071] After filling is completed, the first cylinder 69 is activated, extending to drive the second slider 63 to slide. As the second slider 63 moves, it moves the pull rope 60, pulling the discharge port 5 upwards, causing it to detach from the inner bag. Simultaneously, the sliding of the second slider 63 drives the first slide rail 61 and the clamping plate 65 at the bottom of the first slider 64 to move. At this time, the two sets of clamping plates 65 holding the inner bag opening move in opposite directions, straightening the inner bag opening. Once the inner bag opening is straightened, both second cylinders 72 are activated simultaneously. After cylinder 72 extends, it pushes the movable frame 71, causing the top of the movable frame 71 to rotate, which in turn drives the clamping strip 73 at the bottom to move. Finally, the two clamping strips 73 merge together, clamping the taut bag opening in the middle. At the same time, the heat generated by the electric heating plate 74 melts the bag opening of the inner bag, making the bag opening sealed. Finally, the second cylinder 72 is controlled to retract, causing the two clamping strips 73 to return to their original positions, thus completing the sealing of the inner bag. After the inner bag is sealed, the first motor 67 is started again. Similarly, it can drive the clamping plate 65 to move in the opposite direction, causing the inner bag to fall into the outer bag.

[0072] Then, the conveyor 2 and the transverse slide 814 are started. When the conveyor 2 is running, it drives the woven bag to move towards the sealing machine 3. When the transverse slide 814 is running, it drives the transverse slide block 817 to move towards the sealing machine 3. The transverse slide block 817 drives the vertical slide block 815, the crossbeam 801, and the strip rod 804 on the crossbeam 801 to move with the woven bag. Then, the third cylinder 812 is started. The third cylinder 812 drives the double-sided rack 813 to slide. The double-sided rack 813 first contacts the first driven gear 909 and drives the first... When the driven gear 909 rotates, it drives the second base shaft 902 and the third bevel gear 908 to rotate. The third bevel gear 908 then drives the fourth bevel gear 907 to rotate. The fourth bevel gear 907 then drives the rotating shaft 905 to rotate. The rotating shaft 905 drives the mounting bracket 903 and the base plate 904 on the mounting bracket 903 to rotate, causing the torsion spring 906 to deform. After rotating, the base plate 904 enters the outer bag and presses down on the top of the inner bag, causing the top of the inner bag to retract inwards. The double-sided rack 813 disengages from the first driven gear 909, and under the elastic force of the torsion spring 906, the mounting bracket 903 and the base plate 904 rotate and reset. Then, the double-sided rack 813 meshes with the second driven gear 809 and drives the second driven gear 809 to rotate. When the second driven gear 809 rotates, it drives the first base shaft 807 and the first bevel gear 810 to rotate. The rotation of the first bevel gear 810 drives the second bevel gear 811 to rotate. The rotation of the second bevel gear 811 drives the second bidirectional screw 806. When the second bidirectional screw 806 rotates, it drives the two strip rods 804 holding the opening of the outer bag to move closer to each other until they fit together, thus closing the opening of the outer bag. When the woven bag moves into the sealing machine 3, the vertical slide table 815 rotates, driving the vertical slide block 818 to move upward. When the vertical slide block 818 moves upward, it drives the crossbeam 801 and the strip rods 804 on the crossbeam 801 to move upward. When the strip rods 804 move upward, the retaining spring disengages from the outer bag, allowing the outer bag to be closed for subsequent sewing.

[0073] By setting a movable feeding port 5 on the filling machine 1, and setting an inner bag clamping component 6 and an inner bag welding component 7 at the feeding port 5, and setting an outer bag holding component 8 between the filling machine 1 and the sealing machine 3, the inner bag of the woven bag is first fixed during filling, and then welded and sealed after filling. Then the outer bag of the woven bag is kept closed until it enters the sealing machine 3. Thus, the double-layer composite woven bag is used to package and transport feed that requires sealing. Compared with manual sealing, it saves time and effort and is more efficient. Compared with common bagging equipment, it improves the sealing performance, which is conducive to product preservation and improves product quality.
