DETAILED DESCRIPTION

[0061] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that although the description of these embodiments is used to help understand the present invention, it does not constitute a limitation of the present invention.

[0062] The specific structural and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0063] See also Figures 1 to 8As shown, the utility model proposes an automatic material packaging equipment, including: a dividing plate 11, which is rotatably connected to a base 13 through a dividing device 12, and the dividing device 12 is used to drive the dividing plate 11 to rotate according to a preset dividing value; a material guiding device 2, one end of which is connected to a feed bin and the other end of which has a discharge port, and the material guiding device 2 is used to divide the material and make the material quantitatively discharged from the discharge port; a bag taking device 3, which is used to take out the packaging bags 10 from the bag bin 101 one by one; a clamping device 4, which is used to clamp the packaging bags 10; a bag opening device 5, which has two suction cups 59 arranged at intervals, and the opening device 5 is used to open the bag 10; and the bag opening device 5 has two suction cups 59 arranged at intervals. The bag device 5 is used to make the suction cup 59 approach or move away from the two side walls of the packaging bag 10 from the opposite side, and the suction cup 59 sucks the side walls of the packaging bag 10 and drives the two side walls to move in opposite directions so as to open the packaging mouth of the packaging bag 10; the bag sealing device 6 is used to seal and close the packaging bag 10 filled with materials; the detection device 102 is used to detect the bag opening state information of the packaging bag 10; and the controller is respectively communicatively connected to the indexer 12, the material guiding device 2, the bag taking device 3, the bag taking device 3, the clamping device 4, the bag opening device 5, the bag sealing device 6 and the detection device 102.

[0064] The clamping device 4 is provided in at least four groups (see in one embodiment of the present disclosure). Figure 2 As shown, the clamping devices 4 are arranged in five groups), and are respectively connected to the dividing plate 11 at intervals; the discharge port of the material guiding device 2 is located above the clamping device 4, and when the dividing plate 11 rotates, the material can just fall into the packaging bag 10; the material guiding device 2 is located between the bag opening device 5 and the bag sealing device 6.

[0065] The working process of the automatic material packaging equipment is summarized as follows: first, the equipment is started, so that the indexing plate 11 starts to rotate. At the same time, the bag taking device 3 drives to take out the packaging bags 10 from the bag bin 101 one by one, and after the clamping device 4 clamps the packaging bag 10, it rotates synchronously with the indexing plate 11. When the clamping device 4 moves to a position relative to the bag opening device 5, the bag opening device 5 absorbs the outer wall of the packaging bag 10 to open and expand the bag mouth of the packaging bag 10; after the detection device 102 detects that the bag mouth of the packaging bag 10 opens to a preset opening threshold, the indexing plate 11 continues to rotate with the clamping device 4 and moves to a position corresponding to the material guiding device 2 and its outlet. In this case, the material guiding device 2 can make the distributed material fall into the bag mouth of the packaging bag 10; thereafter, the clamping device 4 continues to rotate with the indexing plate 11 and moves to a position corresponding to the bag sealing device 6. The bag sealing device 6 seals the packaging bag 10 with the bag opening opened, and then leaves the current sealing position as the indexing plate 11 rotates to be delivered to the unloading area. Thus, the automatic packaging of a single bag of material is completed.

[0066] In addition, it should be noted that the existing packaging machines on the market usually adopt the method of taking bags from the top of the bag storage box. This method requires a propulsion mechanism at the bottom to perform intermittent lifting movements. However, when the bags in the bag bin need to be replenished, the operation of the entire device often needs to be suspended, which will undoubtedly affect the packaging efficiency. The method of taking bags from the bottom can facilitate the staff to add bags to the bag storage bin from the top without stopping the machine.

[0067] Through the above technical scheme, the automatic packaging of bulk materials such as black fungus, shiitake mushrooms, white fungus and other foods can be completed quickly, and the entire packaging process can be completely carried out automatically in a mechanized manner, which not only saves manpower, but also improves packaging efficiency. At the same time, it also reduces the contact between food and human beings during the packaging process, which is beneficial to ensure food hygiene and has good economy and practicality. In addition, the automatic packaging equipment is divided into upper and lower mechanical structures, and the material guiding device 2, the bag taking device 3, the bag opening device 5, and the bag sealing device 6 are arranged in an enclosed manner, which can reduce the occupation of the site location and realize the optimal use of space. The layout of the automatic packaging equipment is orderly, which is also convenient for workers to conduct manual inspections of the working process of the automatic packaging equipment. At the same time, it is also convenient for later maintenance and has good operability.

[0068] In an embodiment provided in the present disclosure, the material automatic packaging equipment also includes a bag mouth maintaining device 7, which includes: a positioning sleeve 71, connected to the base 13, and the positioning sleeve 71 is provided with a U-shaped slide groove 711; a motor 72, whose output shaft extends into the positioning sleeve 71, and the end of the output shaft is provided with a pin 74 adapted to the slide groove 711; a sleeve seat 73, embedded in the positioning sleeve 71 and connected to the pin 74; a clamp 75, having an expansion rod 751 open toward both ends; and a cantilever 76, one end of which is connected to the clamp 75, and the other end is connected to the sleeve seat 73.

[0069] In this way, when the motor 72 rotates, the pin 74 is embedded in the slide groove 711 and moves along the groove of the slide groove 711, so that the cantilever 76 can be raised and lowered and swung. When the bag opening is opened, the cantilever 76 drives the clamp 75 to descend and extend into the packaging bag 10, thereby opening and supporting the bag opening to prevent the bag opening from deforming during the movement, which may cause the subsequent inability to accurately drop the material. After the material falls into the packaging bag 10, the cantilever 76 drives the clamp arm to rise and reset to prepare for the next bag opening shape and size maintenance work.

[0070] In an embodiment provided by the present disclosure, a flexible protective sleeve is provided at the end of the deployment rod 751. Based on the flexible property of the protective sleeve, when the bag opening is opened and maintained, the protective sleeve can protect the bag and prevent it from scratching the packaging bag 10. Specifically, the protective sleeve can be configured as a polyurethane or food-grade rubber sleeve.

[0071] In an embodiment provided in the present disclosure, the bag taking device 3 includes: a mounting seat 31, a bag bin 101 is provided in the upper area of ​​the mounting seat 31; an active connecting rod 32, one end of which is rotatably connected to the mounting seat 31 and is transmission-connected to the output shaft of a micro motor, and the micro motor is connected to the mounting seat 31; a first connecting rod 33, one end of which is rotatably connected to the mounting seat 31; a second connecting rod 34, both ends of which are rotatably connected to the first connecting rod 33 and the active connecting rod 32 respectively, and a clamp 38 is provided at the end of the second connecting rod 34; and a linear telescopic member 35, which has a telescopic shaft that can be telescoped in a linear direction, and the end of the telescopic shaft is connected to a vacuum suction cup 36, and the vacuum suction cup 36 is connected to a first air source.

[0072] When the linear telescopic member 35 is extended, the vacuum suction cup 36 can be brought close to the bag bin 101 and absorb the packaging bag 10 at the bottom of the bag bin 101; the micro motor is started, the active connecting rod 32 rotates and drives the second connecting rod 34 and the first connecting rod 33 to move, so that the clamp 38 can clamp the packaging bag 10 absorbed by the vacuum suction cup 36.

[0073] In the present disclosure, the gripper 38 is configured as a gripper in the prior art, and a rubber pad or a silicone pad is provided on the gripper finger of the gripper. The linear telescopic member 35 is configured as a hydraulic cylinder.

[0074] In the present disclosure, the telescopic shaft is connected to the vacuum suction cup 36 via a guide plate 37; wherein the mounting seat 31 is provided with a guide groove extending in the vertical direction, one end of the guide plate 37 is connected to the telescopic shaft, and the other end is slidably connected to the guide groove. In this way, when the linear telescopic member 35 is extended, the guide plate 37 can be used to improve the stability of the vacuum suction cup 36 during the displacement process, so that the suction port of the vacuum suction cup 36 can effectively adhere to and suck the packaging bag 10, thereby achieving effective bag removal.

[0075] At least two vacuum suction cups 36 are provided and are spaced apart on the guide plate 37 , so that the area of ​​the packaging bag 10 being sucked can be increased, thereby ensuring reliability and stability during the bag taking process.

[0076] In an embodiment provided in the present disclosure, the bag opening device 5 includes: a connecting seat 51; a transverse rail 52, which is provided in two groups, and the two groups of transverse rails 52 are movably connected to the connecting seat 51, and the two are staggered in the vertical direction, and the detection device 102 is provided on the transverse rail 52 located at a high position to be able to detect the opening state information of the packaging bag 10; a driving motor 53, which is provided on the connecting seat 51, and a transmission member 55 is provided at the end of the driving motor 53, and two strip grooves are provided on the transmission member 55; short pins 54, which are provided in two groups and are respectively connected to the transverse rails 52 one by one, and the ends of the short pins 54 are inserted in the strip grooves; and a partition 56, which is provided in two groups and is connected to the transverse rails 52 one by one through a vertical plate 58.

[0077] When the driving motor 53 rotates, the transmission member 55 rotates and pushes the two sets of transverse rails 52 to move in opposite directions, so that the two partitions 56 can move closer to or farther from each other. Specifically, when the driving motor 53 drives the transmission member 55 to rotate counterclockwise, the two transverse rails 52 move in opposite directions, so that the distance between the two partitions 56 increases, thereby opening the bag opening of the packaging bag 10. After the bag opening is opened, when the driving motor 53 drives the transmission member 55 to rotate clockwise, the two transverse rails 52 also move in opposite directions, but can make the partitions 56 approach each other and gradually reduce the distance between them.

[0078] It should be noted that the transmission member 55 and the short pin 54 can be configured as gears, and the two cross rails 52 are provided with tooth grooves adapted to the gears. The gear transmission is connected to the output shaft of the drive motor 53, so that the position between the two partitions 56 is adjusted by the forward or reverse rotation of the drive motor 53.

[0079] It should be noted that the direction of the driving motor 53 mainly depends on its installation position. Under the technical concept of the present disclosure, those skilled in the art can flexibly configure it.

[0080] Furthermore, the vertical plate 58 is provided with a vertical groove 581, and the partition 56 is movably embedded in the vertical groove 581; the bag opening device 5 also includes a pusher 57, the pusher rod of the pusher 57 can be extended and retracted in the vertical direction and the pusher rod is connected to the partition 56 to drive the partition 56 to move along the vertical groove 581. In this way, the partition 56 can be retracted from the bag and reset after the bag mouth is opened, so as to prepare for the next bag opening work.

[0081] The separator 56 is L-shaped or arc-shaped, so that there is a gap between the separator 56 and the vertical plate, which is beneficial to increase the extension range of the separator 56 in the packaging bag 10. At least a flexible buffer sleeve is provided at the end of the separator 56, which can play a certain protective role on the packaging bag 10 and avoid scratching or breaking it. Specifically, the buffer sleeve can be configured with polyurethane or food-grade silicone or rubber.

[0082] In the present disclosure, the automatic material packaging equipment further includes an adding device 8, which is used to put bagged food additives into the packaging bag 10 with the bag mouth opened, so as to alleviate the problem of the influence of long-term moisture contact of the material in the environment. By adding food additives, the shelf life of the product can be increased, thereby playing a role in drying or preserving the material.

[0083] It should be noted that the adding device 8 can be configured as any suitable structure, such as a mechanical arm with a mechanical hand in the prior art, or any other suitable feeding device. Since the adding device 8 is configured as an apparatus in the prior art, it will not be described in detail here.

[0084] In an embodiment provided in the present disclosure, the automatic material packaging equipment also includes a transmission device 9, which is arranged below one group of clamping devices 4, and the transmission device 9 is located in the downstream process of the bag sealing device 6 for circulation of packaged packaging bags 10.

[0085] Specifically, a belt transmission structure is selected as the transmission device 9. Since the transmission device 9 is already a relatively mature product and has been widely used in the transportation of goods, it will not be described in detail here.

[0086] In the present disclosure, the detection device 102 includes a distance measuring sensor to detect the opening state of the bag opening. For example, according to the value range information preset in the controller, it is determined whether the opening distance of the bag opening meets its feeding requirements. When the opening distance of the bag opening is less than the feeding value, the controller issues an instruction to the bag opening device 5 to open and expand the bag opening until the feeding requirements are met. When the opening distance of the bag opening is greater than or equal to the feeding value, the controller issues an instruction to the material guiding device 2 to open the discharge port, so that the material falls into the packaging bag 10 quantitatively.

[0087] The detection device 102 also includes a CCD camera and a laser displacement sensor, so that the bag opening can be opened to a relatively large state by making a more comprehensive and accurate judgment on the bag opening state information, so that the material can fall into the bag smoothly and avoid leakage.

[0088] The term “ / and” that appears in this article describes another type of associative object relationship, indicating that two relationships may exist. For example, A / and B may represent two situations: A exists alone, and A and B exist alone.

[0089] In the present disclosure, the controller is configured as a PLC logic controller.

[0090] Specifically, in the present invention, the controller may also be configured as a central processing unit (CPU). In other embodiments, the controller may also be configured as a digital signal processor (DSP), an application specific integrated circuit (ASIC), or a field programmable gate array (FPGA).

[0091] In the present disclosure, the controller is respectively connected to the indexer 12, the material guide device 2, the bag taking device 3, the bag taking device 3, the clamping device 4, the bag opening device 5, the bag sealing device 6 and the detection device 102 through cables. In other embodiments, the controller can also be connected to the indexer 12, the material guide device 2, the bag taking device 3, the bag taking device 3, the clamping device 4, the bag opening device 5, the bag sealing device 6 and the detection device 102 through wireless communication modules such as WiFi modules and ZigBee modules. In this regard, those skilled in the art can flexibly configure it under the technical concept of the present disclosure.

[0092] In one embodiment, the clamping device 4 includes a gripper 41, a slide rail 42, a triangular seat 43, a spring 44, a round pin 45 and a cam 46, the slide rail 42 is arranged on the chassis, the triangular seat 43 is connected to the chassis by a hinge support, one end of the triangular seat is connected to the gripper 41, and the other end is connected to the connecting rod; one end of the spring 44 is connected to the chassis through a fixed block, and the other end is sleeved on the connecting rod; the connecting rod is provided with a round pin 45 with point contact with the cam 46; when the cam 46 rotates clockwise, the round pin 45 approaches the axis of the cam 46 under the action of the spring 44, and at the same time, the connecting rod moves toward the cam 46 and drives the triangular seat 43 to rotate counterclockwise around the fixed hinge support, so that the gripper 41 shrinks inward along the slide rail 42 to adapt to the packaging bag 10 in the bag opening state.

[0093] Among them, the cam is conventionally connected to the driving motor. The cam 46 rotates clockwise, and the round pin 45 moves closer to the axis of the cam 46 under the action of the spring force, driving the connecting rod to move to the side of the cam 46. Then, the connecting rod drives the triangular seat 43 to rotate counterclockwise around the fixed hinge support so that the gripper 41 shrinks inward along the slide rail 42 to adapt to the width of the packaging bag 10 when the bag is opened, that is, the clamping device 4 adapts to the change of the bag opening. When the motor drives the cam 46 to rotate counterclockwise, the round pin 45 moves away from the axis of the cam 46 under the action of the spring force, driving the connecting rod to move to the side of the gripper 41. Then, the connecting rod drives the triangular seat 43 to rotate clockwise around the fixed hinge support so that the gripper 41 stretches outward along the slide rail 42 to smooth the bag opening, which is convenient for the subsequent bag sealing device 6 to seal.

[0094] For other devices in the present disclosure, such as the indexer 12, the material guiding device 2, the clamping device 4 (which can also be equipped with a robot or other types of clamps), the bag sealing device 6 (hot melter, press), the clamp 75, the clamps and other structures are all selected products in the existing technology. For this, technical personnel in this field can make routine improvements according to the material type, or directly use commercially available mechanical equipment.

[0095] In a preferred embodiment provided by the present disclosure, the material guide device 2 includes an elevator and a combination weigher. The elevator lifts the fungus to the feed port of the combination weigher. The combination weigher includes a distributor, a pusher, a preparation hopper and a weighing hopper. The distributor drives the spring to shake up and down through the cam, so that the fallen fungus spreads around. The pushers arranged around push a small amount of fungus to the preparation hopper for buffering through the eccentric wheel mechanism. The fungus in the preparation hopper falls into the weighing hopper for weighing. The computer selects a combination scheme closest to the target weight through permutations and combinations. The weighing hopper involving the combination scheme opens, and the fungus falls into the lower pipe and enters the bag mouth of the packaging bag 10. At the same time, the preparation hoppers above these weighing hoppers are replenished with fungus through the upper pushers. When the computer permutations and combinations fail to select a combination scheme within a reasonable error range, these preparation hoppers are opened again. After the fungus falls into the weighing hopper, the computer permutes and combines again to select a combination scheme. Finally, if the computer still does not select the most suitable combination scheme, the computer will appropriately expand the error to select a combination scheme closest to the target weight to execute and record.

[0096] The bag loading module delivers the packaging bag 10 to the clamping device on the indexing plate 11 through the hydraulic cylinder and the 90° flip mechanism, and clamps it through the clamping device. The bag opening module opens the bag mouth through the bag opening mechanism and the vacuum suction cup 36, and the clamping device contracts inward to adapt to the width of the bag mouth. The bag opening maintenance module is composed of the end clamp and the connecting rod that moves in a U-shaped trajectory. When the bag mouth is opened, the connecting rod of the bag opening maintenance module descends, and the end clamp extends into the inside of the packaging bag 10 to open and support the bag mouth to prevent the bag mouth from deforming during the movement, causing the subsequent inability to accurately drop the material. Then the connecting rod follows the central intermittent turntable to rotate one station to the bottom of the drop mouth. At this time, the connecting rod of the bag opening maintenance module rises, and the end clamp closes and returns to the bag opening module. At the same time, the telescopic rod above the packaging bag 10 drives the hopper to extend into the packaging bag 10, and then the food desiccant and the fungus that falls from the pipe below the combination weigher fall into the packaging bag 10 together. When all the materials fall into the packaging bag 10, the grippers of the clamping device 4 of the central intermittent turntable extend outward to flatten the bag opening, and the subsequent bag sealing module drives the heating rod to heat-seal the bag opening, and this cycle repeats until bags of fungus are sent to the storage box at the rear along the conveyor belt.

[0097] To ensure that the desiccant and the fungus fall into the bag accurately, a telescopic rod 103 is designed. When the packaging bag 10 follows the indexing plate 11 to this position, the telescopic rod 103 descends, and the lower end feed port is extended into the packaging bag 10, and then the desiccant and the material above fall through this device into the packaging bag 10.

[0098] It should be noted that the utility model is not limited to the above optional implementations, and anyone can derive other various forms of products under the inspiration of the utility model. The above specific implementations should not be understood as limiting the scope of protection of the utility model. The scope of protection of the utility model shall be based on the definition in the claims, and the description can be used to interpret the claims.
