Description

Technical Field

[0001] The invention relates to the technical field of full-automatic bulk material packaging, in particular to a multi-purpose full-automatic bulk material packaging method and equipment. Background Art

[0002] ‌Fully automatic bulk packaging equipment‌ is a packaging equipment that can automatically complete the processes of metering, filling, bag making, sealing, cutting, conveying, etc. It is suitable for various bulk materials, such as powders, granules, tablets, etc., and is widely used in food, medicine, chemical and other industries.

[0003] However, the existing fully automatic bulk packaging equipment has the following disadvantages: (1) When the shape and size of the matrix bag changes, the adjustment of the machine is more troublesome. First, the matrix bag forming mold needs to be replaced, and even if it is a combined mold, the adjustment is also troublesome. Secondly, when the height of the matrix bag becomes smaller (or larger), the height of its forming mold must also become smaller (or larger). However, because of the hot melt sealing, the material at the sealing point will affect the fusion and reduce the sealing quality. Therefore, in order to prevent the material from being scattered at the position to be sealed, the material needs to be in a relatively closed space from the time the material is discharged from the silo until it is filled into the forming mold. Therefore, in the existing equipment, except for the silo and the fixed material box below, almost all the mechanical components need to change their height position to adapt to the height of the forming mold, which is very troublesome to adjust; (2) It can only produce matrix bags, which have a relatively single purpose. For example, compared with matrix bags, edible fungus bags are just cylindrical in shape because they contain more materials. However, existing equipment cannot fully automate the production of edible fungus bags. At present, most of the popular edible fungus bag production equipment on the market is semi-automatic. The bag taking, bag opening, and bag tying (sealing) after filling are all done manually. A few fully automatic equipment, such as automatic bagging and tying machines, not only have a more complex tying system, but also require manual bag taking and bag opening. Another type of equipment that replaces manual bag taking and bag opening uses a pneumatic system to obtain negative pressure between the robot and the film to achieve the purpose of bag taking and bag opening. These types of fully automatic equipment have complex structures and high costs.

[0004] Based on the above, a multi-purpose fully automatic bulk material packaging method and equipment is invented. Summary of the invention

[0005] In view of the above and / or existing problems in a conventional multi-purpose fully automatic bulk material packaging method and device, the present invention is proposed.

[0006] Therefore, the object of the present invention is to provide a multi-purpose fully automatic bulk packaging method and equipment, which can solve the above-mentioned existing problems.

[0007] To solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions: A multi-purpose fully automatic bulk material packaging method comprises the following specific steps: Step 1: Disconnect the first electromagnetic clutch and the second electromagnetic clutch, and turn on the main motor. At this time, the arch-breaking mixer in the silo will work. When the mixed material fills the capacity space V12 of the cross-fixed silo, the second electromagnetic clutch is closed, and the chain drive drives the cross-fixed silo to rotate clockwise. When it rotates too much, the material in the capacity space V11 falls and fills into the feeding silo. At the same time, the material in the silo fills the capacity space V21. The cross-fixed silo continues to rotate. When it rotates another degree, the material in the capacity space V12 falls and fills into the feeding silo. At the same time, the material fills the capacity space V22. At this time, the second electromagnetic clutch is disconnected, and the cross-fixed silo that has rotated too much continuously stops. Step 2: The second motor drives the gear rack to drive the film clamping and film sleeve device to move to the right, so that the elastic movable pressing piece extends into the tube film opening. At this time, the electromagnet connected to the fixed outer ring is energized to generate magnetism, so that a number of elastic movable pressing pieces press the tube film tightly against the fixed outer ring. Then, the second motor reverses to drive the gear rack to drive the film clamping and film sleeve device to move to the left, and sleeve it on the outer circumference of the discharge port of the feeding bin. Step 3: The third motor drives the bidirectional spiral screw to rotate, so that the sliders on the bag bottom sealing and shearing device move toward each other, realize sealing and shearing, and complete the bag making work. After that, the third motor is stopped. At this time, the slider on the bag bottom sealing and shearing device will stop at the sealing and shearing position and remain motionless, so that the bag holding and fixing bag shell fixed on a group of sliders is buckled on the upper surface of the bag; Step 4: Open the first electromagnetic clutch to make the chain drive drive the nut screw to work, so that the nut screw pushes the push scraper forward, pushes the material in the feeding bin into the newly made bag, and presses it appropriately, then, the nut screw and the push scraper return to the leftmost end of the feeding bin, and the first electromagnetic clutch is disconnected; Step 5: The first motor drives the forward and reverse screws of the bag sealer to rotate, so that the pressure head and the base move toward each other to achieve sealing, and then the first motor reverses to return the pressure head and the base to their original positions; Step 6: The electromagnet on the film clamping and film sleeve device is powered off and demagnetized. At this time, the elastic movable pressing piece rebounds under the action of the spring to release the tube film. At the same time, the third motor reverses to drive the slider on the bag bottom sealing and cutting device to completely return to its original position; Step 7: Roll the finished material bags down along the bag unloading slope to complete the packaging process of one material bag. This cycle is repeated to enable full automatic production until the required number of material bags are completed.

DETAILED DESCRIPTION

[0020] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] The present invention provides a multi-purpose fully automatic bulk material packaging method, please refer to Figure 1-Figure 14 , including the following specific steps: Step 1: Disconnect the first electromagnetic clutch 2 and the second electromagnetic clutch 3, and turn on the main motor 1. At this time, the arch-breaking mixer 5 in the silo 4 will work. When the mixed material fills the storage space V12 of the cross-fixed silo 6, the second electromagnetic clutch 3 is closed, and the chain drive drives the cross-fixed silo 6 to rotate clockwise. When it rotates 90 degrees, the material in the storage space V11 falls and fills into the feeding silo 8. At the same time, the material in the silo 4 fills the storage space V21, and the cross-fixed silo 6 continues to rotate. When it rotates another 90 degrees, the material in the storage space V12 falls and fills into the feeding silo 8. At the same time, the material fills the storage space V22. At this time, the second electromagnetic clutch 3 is disconnected, and the cross-fixed silo 6 that has rotated 180 degrees continuously stops. Step 2: The second motor 15 drives the gear rack 14 to drive the film clamping and sleeve film device 13 to move to the right, so that the elastic movable pressing plate 132 extends into the tube film opening. At this time, the electromagnet 134 connected to the fixed outer ring 131 is energized to generate magnetism, so that a number of elastic movable pressing plates 132 press the tube film tightly against the fixed outer ring 131. Then, the second motor 15 reverses to drive the gear rack 14 to move the film clamping and sleeve film device 13 to the left, and sleeve it on the outer circumference of the discharge port of the feeding bin 8. If the material bag is a cylinder, the feeding bin 8 and its discharge port are in the shape of a circular tube, and the tube film will be sleeved on the outer circumference of the discharge port. Note: In order to save time, the first and second steps can be overlapped appropriately according to the working time of each step; Step 3: The third motor 17 drives the bidirectional spiral screw to rotate, so that the sliders on the bag bottom sealing and shearing device 18 move toward each other, so as to achieve sealing and shearing, and complete the bag making work. After that, the third motor 17 stops rotating, and the sliders on the bag bottom sealing and shearing device 18 stop at the sealing and shearing position, so that the bag holding and fixing bag shell 19 fixed on a group of sliders is buckled on the upper surface of the bag; Step 4: Open the first electromagnetic clutch 2 to make the chain drive drive the nut screw 9 to work, so that the nut screw 9 pushes the push scraper 10 forward, pushes the material in the feeding bin 8 into the newly made bag, and presses it appropriately, leaving a space of length L near the bag mouth. The size of L is based on the principle that the material collapses after the scraper 10 leaves and does not affect the sealing. If the L space that can be provided cannot meet the needs and affects the sealing effect, then the material humidity and the pressing force of the feeding scraper 10 on the material at the bag mouth can be appropriately increased. Then, the nut screw 9 and the push scraper 10 are returned to the leftmost end of the feeding bin 8, and the first electromagnetic clutch 2 is disconnected; Step 5: The first motor 12 drives the forward and reverse screw rods 111 of the bag sealer 11 to rotate, so that the pressing head 112 and the base 113 move toward each other to achieve sealing, and then the first motor 12 is reversed to return the pressing head 112 and the base 113 to their original positions; Step 6: The electromagnet 134 on the film clamping and film sleeve device 13 is powered off and demagnetized. At this time, the elastic movable pressing piece 132 rebounds under the action of the spring to release the tubular film. At the same time, the third motor 17 reverses and drives the slider on the bag bottom sealing and cutting device 18 to completely return to its original position; Step 7: Roll the finished material bag down along the bag unloading slope 16 to complete the packaging process of one material bag. This cycle is repeated to enable full-automatic production until the required number of material bags are completed.

[0022] A multi-purpose fully automatic bulk material packaging equipment, including a main motor 1, a first electromagnetic clutch 2, a second electromagnetic clutch 3, a silo 4, an arch-breaking mixer 5, a cross-fixing silo 6, a fan-shaped fixing adjustment column 7, a feeding silo 8, a nut screw 9, a material pushing scraper 10, a bag mouth sealer 11, a first motor 12, a film clamping and film sleeve device 13, a gear rack 14, a second motor 15, a bag unloading slope 16, a third motor 17, a bag bottom sealing and shearing device 18, a bag holding and solidifying bag shell 19, an opener 20 and a frame 21. The main motor 1 is fixedly installed on the left side of the frame 21, and the silo 4 is fixedly installed on the frame 21 located on the right side of the main motor 1. The silo 4 is rotatably connected to the arch-breaking mixer through a bearing. 5, and the output shaft of the main motor 1 is fixedly connected to the arch-breaking mixer 5, a cross-fixed material bin 6 is provided at the bottom end of the silo 4, and the silo 4 and the cross-fixed material bin 6 are in an intercommunication state, a feeding bin 8 is provided at the bottom end of the cross-fixed material bin 6, and the feeding bin 8 and the cross-fixed material bin 6 are in an intercommunication state, the feeding bin 8 is fixedly installed on the frame 21, a film clamping and sleeve film device 13 is provided on the frame 21 located at the discharge port of the feeding bin 8, a bag mouth sealer 11 is provided on the frame 21 located at the discharge port of the feeding bin 8, a bag bottom sealing and shearing device 18 is provided on the frame 21 located on the right side of the bag mouth sealer 11, and a mouth opener 20 is provided on the frame 21 located on the right side of the bag bottom sealing and shearing device 18; The right half of the feeding bin 8 is a round tube, while the left half (such as Figure 7 The c1-c2 section shown in the figure needs to be filled with materials from the cross-fixed feeding bin 6. Therefore, the tube wall of the left end of the circular tube of the feeding bin 8 is cut off at the longitudinal connection line with the cross-fixed feeding bin 6, that is, the c1-c2 sections of the two at the connection are connected. Generally, the outer packaging of the material bag is made of soft material (such as plastic film, etc.). Therefore, whether it is a pillow-shaped bag (such as a matrix bag) or a cylindrical bag (such as a mushroom stick), a circular tubular feeding bin can be used to hold the filling bag. However, if the outer packaging of the material is made of a hard material (such as hard and thick paper, etc.) into a rectangular cylindrical bag, then the feeding bin 8 can also be made into a rectangular tube.

[0023] A cross partition that can rotate around the central axis is provided in the cross material bin 6, and the main motor 1 is connected to the cross partition through the second electromagnetic clutch 3. The cross partition divides the inner cavity of the cross material bin 6 into four columnar material storage spaces, which are V11, V12, V21 and V22 respectively, and a fan-shaped material adjustment column 7 is inserted in the material storage space; Among them, V11 and V12 are cylindrical spaces with fan-shaped cross-sections, V21 and V22 are cylindrical spaces surrounded by arcs, and the materials in the four cylindrical material storage spaces just meet the needs of two material bags. For example: Figure 6 The two material storage spaces V21 and V22 filled with material just meet the usage of one material bag. The other half of the material is being sent to the bag by the material pusher 10 in the feeding bin 8. If the material bag is small and the required material is less than the amount that the cross-fixed bin 6 can provide, then the excess material storage space can be blocked to reduce the material filling. In the present invention, in the two larger material storage spaces ( Figure 6 V11 and V21 in the figure are inserted into two sector-shaped material adjustment columns 7, and the insertion depth is determined according to the actual requirements of the material bag. The sector-shaped material adjustment column 7 is a column with a sector-shaped cross-section.

[0024] A nut screw 9 is rotatably connected in the feeding bin 8 , and the main motor 1 is connected to the nut screw 9 through the first electromagnetic clutch 2 . A push scraper 10 is provided on the nut screw 9 , and the push scraper 10 is slidably connected in the feeding bin 8 .

[0025] A second motor 15 is fixedly mounted on a frame 21 located at the discharge port of the feeding bin 8 , and the second motor 15 is connected to the film clamping and film sleeve device 13 via a gear rack 14 .

[0026] The film clamping and film sleeve device 13 includes a connecting frame 133 , which is arranged on the gear rack 14 , and a fixed outer ring 131 is fixedly installed on one side of the connecting frame 133 , in which a plurality of elastic movable pressing sheets 132 are arranged, and an electromagnet 134 is arranged on the outer surface of the fixed outer ring 131 .

[0027] The bag bottom sealing and cutting device 18 includes side plates fixedly mounted at both ends of the frame 21, and a bidirectional spiral screw is rotatably connected between the two sets of side plates through bearings, and both ends of the bidirectional spiral screw are threadedly connected to sliders, and one set of sliders is fixedly mounted on the bag holding and fixing bag shell 19, and a third motor 17 is fixedly mounted on one set of side plates, and the third motor 17 is fixedly connected to the bidirectional spiral screw.

[0028] The bag sealer 11 includes square plates fixedly mounted at both ends of the frame 21, and the two sets of square plates are rotatably connected to the forward and reverse screw rods 111 through bearings, and the two ends of the forward and reverse screw rods 111 are respectively threadedly connected to the pressure head 112 and the base 113, and the first motor 12 is fixedly mounted on one set of square plates, and the output shaft of the first motor 12 is fixedly connected to the forward and reverse screw rods 111. Among them, the bag sealer 11 is similar to a bag-stitching (sealing) device in which a number of staplers are arranged together.

[0029] The mouth opener 20 includes a connecting bracket 201 fixedly mounted on a frame 21, a bearing shaft 202 is fixedly mounted on one side of the connecting bracket 201, and a plurality of rollers 203 are rotatably connected to the bearing shaft 202; if the film mouth needs to be opened into a circle, then the arc radius R of the four rollers 203 is the same. If the film mouth needs to be opened into other shapes, then R is arbitrary.

[0030] A bag unloading inclined plane 16 is fixedly mounted on one side of the frame 21 for bag unloading.

[0031] In order to prevent the film bag from being torn off the film clamping and film sleeve device 13, or being torn or broken, or causing the bag to shift, swell, or fall, etc., when filling the material, due to the excessive feeding pressure of the feeding scraper 10, a bag holding and fixing shell 19 is designed to protect and fix the circumference of the material bag. After the sealing is completed, the upper and lower ends of the sealing head are left here without returning, or slightly return a safe distance (during hot melt sealing) to protect and fix the bottom surface of the material bag. The bag holding and fixing shell 19 is fixed together with the upper half of the slider of the bag bottom sealing and shearing device 18, and the movement direction of the two is perpendicular to the bag unloading slope 16, so that the bag holding is effective. When hot-melt sealing is used, in order to prevent the sealed bag from being burned and damaged, after the sealing is completed, the sealing heads on both sides of the sealer should be relatively separated by a safe distance L. At this time, the bag holding and solid bag shell 19 will be away from the bag and make the bag holding ineffective. Therefore, before the machine works, the bag holding and solid bag shell 19 should be adjusted to move a distance L in the direction close to the bag unloading slope 16, so that after the sealing is completed, the bag holding and solid bag shell 19 can still hold the bag effectively after the sealing heads on both sides of the sealer are separated by a distance L. However, in this case, when the bag mouth sealer 11 is sealing, the left edge of the bag holding and solid bag shell 19 will interfere with the bag unloading slope 16 (the right edge is higher than the upper side of the bag unloading slope 16), so it is necessary to open a narrow slit at the corresponding position of the bag unloading slope 16 in advance to avoid interference.

[0032] In addition, the preparation and adjustment before the present invention works have the following process: Process 1: Select appropriate cross-shaped material bin 6, fan-shaped material adjustment column 7, feeding bin 8 and feeding scraper 10, film clamping and film sleeve device 13, and mouth opener 20, and assemble them; Process 2: Adjust the size of the material storage space of the cross material storage bin 6 by using the fan-shaped material storage adjustment column 7, that is, the depth of the fan-shaped groove inserted into the cross material storage bin 6 (blocking the excess material storage space); Process 3: Fill the fan-shaped cylindrical material storage space V11 of the cross-fixing bin 6 with the evenly mixed materials, and rotate the cross-fixing bin 6 90 degrees clockwise; Process 4: Adjust the bag mouth sealer 11 and the bag bottom sealer 18, install staples etc. as needed, adjust the bag holding and fixing shell 19 connected with the bag bottom sealer 18, and make it able to effectively fix the finished bag after filling the material; Process 5: A tubular film of corresponding size is rolled and hung on the frame 21, and the roller 203 is placed in the tubular film. At this time, the opening of the tubular film can be pulled forward until it is flush with the cutting edge of the bag bottom sealing and cutting device 18.

[0033] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources.
