Description

Technical Field

[0001] This utility model belongs to the technical field of unpacking equipment, specifically relating to a sterile automatic unpacking machine. Background Technology

[0002] Packaging unpacking machines are widely used in industries such as chemical, pharmaceutical, food, and building materials that require the processing of bagged powdery materials.

[0003] Most existing unpacking machines have a conveyor mechanism inside the machine casing to transport materials, with unpacking blades installed on the conveyor mechanism and a discharge port at the bottom of the casing. During operation, as the materials are being transported, the unpacking blades on the upper side open the material bags, allowing the materials to continue being transported forward. This allows the powdery material inside the material bags to fall directly into the material outlet at the end of the conveyor mechanism.

[0004] Because of the large height difference between the conveying mechanism and the discharge port at the bottom of the machine casing, the drop height difference of the material is large, which generates a lot of dust during the drop process.

[0005] To address this issue, the applicant developed an unpacking mechanism comprising a conveying component, a tilting component, a hooking component, and a cutting component. The conveying component transports materials; the tilting component's power output is connected to the conveying component to drive it to tilt downwards; the hooking component is connected to the conveying component to hook the material bags on it; and the cutting component, located below the conveying component, cuts the material bags on the tilted conveying component. During unpacking, the conveying component is tilted downwards first, then the material bags are cut. This tilting significantly reduces the drop height difference, thereby effectively reducing dust generation during the material drop process.

[0006] During use, it was found that because the conveyor component needs to be tilted downwards, its length is relatively short to reduce the space required and make the structure more compact. It can typically only hold one bag of material. Therefore, after the unpacking machine completes the unpacking of one bag and the conveyor component resets, it is usually necessary to manually move the bag onto the conveyor component. This results in a slow cycle time, and it is difficult for a person to place the material in the middle of the conveyor component in one go. Material misalignment can easily lead to incomplete cutting of the bag, resulting in a large amount of residual material. Utility Model Content

[0047] Please refer to the following: Figures 1 to 9 The aseptic automatic unpacking machine provided by this utility model will now be described. The aseptic automatic unpacking machine includes a main unpacking machine, a support frame 101, a temporary storage and conveying assembly 102, and a centering and correction assembly. The main unpacking machine has a housing 70, with a feed inlet on one side. The main unpacking machine receives bagged materials and performs unpacking operations. The support frame 101 is fixedly mounted on the side where the feed inlet of the main unpacking machine is located. The temporary storage and conveying assembly 102 is connected to the support frame 101, and the end of the temporary storage and conveying assembly 102 in the conveying direction is connected to the feed inlet for temporary storage. Materials; the centering and correction assembly includes a mounting frame 111, a correction drive mechanism, and two centering plates 113. The mounting frame 111 is connected to the support frame 101. The two centering plates 113 are spaced apart on the upper side of the temporary storage and conveying assembly 102, and the extension direction of the centering plates 113 is parallel to the conveying direction of the temporary storage and conveying assembly 102. The correction drive mechanism is connected to the mounting frame 111, and the power output end is connected to the two centering plates 113 to drive the two centering plates 113 to move towards or away from each other.

[0048] It should be noted that the main unit of the unpacking machine can be any type of unpacking machine.

[0049] The temporary conveyor assembly 102 can be an existing belt conveyor, chain conveyor, or powered roller conveyor, etc. The centering plate 113 is a flat plate with a certain thickness.

[0050] Preferably, in this embodiment, the temporary storage and conveying component 102 is a belt conveyor.

[0051] The beneficial effects of the aseptic automatic unpacking machine provided by this utility model are as follows: Compared with the prior art, the aseptic automatic unpacking machine provided by this utility model has a temporary storage and conveying component 102 on the outside of the feed inlet. During operation, the temporary storage and conveying component 102 stores several bags of materials. When the unpacking machine completes the unpacking operation of one bag of materials, the temporary storage and conveying component 102 can directly convey the next bag of materials into the unpacking machine through the feed inlet. Compared with manual handling, it can effectively speed up the cycle. In addition, a centering and correction component is set on the upper side of the temporary storage and conveying component 102. The correction drive mechanism drives two centering plates 113 to move in opposite directions, which can push the deviated materials to the center, effectively avoiding the situation of incomplete cutting of material bags due to material deviation, ensuring the cutting effect and reducing material residue.

[0052] like Figure 2 , Figure 4 and Figure 5 As shown, in a specific embodiment of the aseptic automatic unpacking machine provided in this utility model, the correction drive mechanism includes two first drive elements 114, both of which are connected to the mounting frame 111, and the power output end is connected to two centering plates 113 respectively.

[0053] It should be noted that the first driving element 114 is a cylinder, but it can also be a hydraulic cylinder, an electric actuator, or other device capable of outputting axial displacement. Preferably, the first driving element 114 is a cylinder, with two cylinders arranged opposite each other and staggered, and the piston rod connected to the centering plate 113. During operation, the two cylinders move synchronously towards or away from each other, pushing the material bag on the temporary storage conveying assembly 102 to the center.

[0054] like Figure 1 and Figure 2 As shown, in a specific embodiment of the aseptic automatic unpacking machine provided in this utility model, a correction cover 112 is also included. The correction cover 112 is placed on the outside of the mounting frame 111 and connected to the mounting frame 111.

[0055] Specifically, the alignment cover 112 is fixedly mounted on the mounting bracket 111 using screws or bolts. The center plate 113 and the first drive element 114 are both located inside the alignment cover 112 to form a protective structure.

[0056] like Figure 2 and Figure 4 As shown, in a specific embodiment of the aseptic automatic unpacking machine provided in this utility model, the centering and correction component further includes a plurality of guide rods 115, which are arranged in parallel to each other and connected to the mounting frame 111. The centering plate 113 is slidably engaged with the guide rods 115.

[0057] Specifically, two guide rods 115 are provided to make the centering plate 113 more evenly stressed and prevent the centering plate 113 from twisting or deforming; a linear bearing is installed on the centering plate 113, and the guide rods 115 pass through the linear bearing to reduce friction.

[0058] like Figure 1 and Figure 2 As shown, in a specific embodiment of the aseptic automatic unpacking machine provided in this utility model, a control cabinet 121 is also included. The control cabinet 121 is located below the temporary storage and conveying assembly 102 and is connected to the support frame 101. The support frame 101 is connected to the housing 70. The control cabinet 121 is used to house existing control modules for controlling the actions of each mechanism and existing power modules for supplying power to each mechanism.

[0059] It should be noted that the control cabinet 121 is placed on the lower side of the temporary storage and conveying component 102, which makes reasonable use of space and makes the structure more compact, while providing effective support for the temporary storage and conveying component 102.

[0060] like Figure 1 and Figure 2 As shown, in a specific embodiment of the aseptic automatic unpacking machine provided in this utility model, a plurality of cable conduits 122 are also included. One end of each cable conduit 122 is connected and communicated with the control cabinet 121, and the other end is connected and communicated with the machine housing 70. The inside of the cable conduit 122 is used to accommodate cables, so that there are no exposed cables on the outside, making the overall appearance look cleaner. At the same time, it protects the cables and prevents them from being damaged by external forces.

[0061] like Figure 1 As shown, in a specific embodiment of the aseptic automatic unpacking machine provided in this utility model, a door opening and closing assembly is also included. The door opening and closing assembly is located at the feed inlet of the machine housing 70 and connected to the machine housing 70, and is used to control the opening and closing of the feed inlet. The door opening and closing assembly includes a door panel 132 and a door opening and closing drive assembly. The door panel 132 is slidably engaged with the machine housing 70, the door opening and closing drive assembly is connected to the machine housing 70, and the power output end is connected to the door panel 132 to drive the door panel 132 to slide.

[0062] Specifically, such as Figure 1 As shown, in a specific embodiment of the aseptic automatic unpacking machine provided in this utility model, the door opening and closing drive assembly includes two rodless cylinders 131. The two rodless cylinders 131 are respectively located on both sides of the feed inlet and connected to the machine housing 70. The door panel 132 is fixedly connected to the slider of the rodless cylinder 131.

[0063] It should be noted that the rodless cylinder 131 refers to a cylinder that uses a piston to directly or indirectly connect to an external actuator, causing it to reciprocate along with the piston. The biggest advantage of this type of cylinder is that it saves installation space. It is divided into magnetic coupler rodless cylinder 131 (magnetic cylinder) and mechanical rodless cylinder 131.

[0064] The magnetically coupled rodless cylinder 131 transmits power through magnetic coupling. Its core consists of a cylinder barrel, a piston with an internal permanent magnet ring, and an external magnetic ring slider. A set of high-strength permanent magnet rings is mounted on the piston. The magnetic lines of force interact with another set of magnetic rings inside the outer slider through the thin-walled cylinder barrel. Because the two sets of magnetic rings have opposite magnetic properties, they have a strong mutual attraction. When the piston is pushed by air pressure inside the cylinder barrel, the piston moves. Simultaneously, the magnetic rings inside the outer slider are affected by the magnetic lines of force of the magnetic rings on the piston, causing them to move synchronously.

[0065] The mechanical rodless cylinder 131 employs a mechanical linkage between the piston holder and the slider. The piston is directly connected to the external slider via an axial groove in the cylinder barrel, and the groove is sealed by a sealing strip and a dustproof strip. When compressed air drives the piston, the mechanical structure drives the slider to move, providing strong load capacity and high-speed performance.

[0066] Preferably, in this embodiment, a magnetically coupled rodless cylinder 131 is used. When unpacking is performed inside the unpacking machine, the rodless cylinder 131 drives the door plate 132 to slide to the feed inlet, sealing the feed inlet. This effectively prevents internal dust from overflowing and external dust from entering the machine casing 70. After unpacking one bag of material, the rodless cylinder 131 drives the door plate 132 to slide away from the feed inlet, opening the feed inlet and controlling the temporary storage conveying component 102 to convey one bag of material to the feed inlet.

[0067] Preferred, such as Figure 3 and Figure 4 As shown, the unpacking machine main unit also includes at least a flipping conveyor assembly and a cutting assembly. The flipping conveyor assembly includes a conveying assembly, a flipping assembly, and a hook assembly. The conveying assembly includes two mounting plates 11 and a conveying mechanism, with the two mounting plates 11 spaced apart. The conveying mechanism is located between the two mounting plates 11 and connected to them. A sealing box 12 is provided on the opposite side of the two mounting plates 11, and the sealing box 12 is connected to the mounting plates 11. The second drive assembly, the third drive assembly 34, and the transmission assembly are all located inside the sealing box 12. This effectively protects the second drive assembly, the third drive assembly 34, and the transmission assembly, preventing dust from entering and ensuring their service life. At the same time, it reduces hygiene dead corners, making cleaning easier and meeting aseptic requirements.

[0068] Specifically, such as Figure 6As shown, the sealing box 12 consists of a side panel and a cover. One side panel is fixed and sealed to the mounting plate 11, and the other side is detachably connected to the cover by bolts or screws. A sealing ring is provided between the cover and the side panel to improve the sealing performance.

[0069] like Figure 6 and Figure 7 As shown, the hook assembly includes several hooks and a second drive assembly. The hooks are spaced apart along the conveying direction of the conveying assembly. The hooks include a first shaft 51 and multiple hooks 52. The multiple hooks 52 are spaced apart on the first shaft 51 and connected to the first shaft 51. The two ends of the first shaft 51 are rotatably engaged with the conveying assembly. The ends of the hooks 52 are spike-shaped.

[0070] It should be noted that the conveying mechanism is a roller, belt, or chain conveyor.

[0071] Preferred, such as Figures 6 to 9 As shown, the conveying mechanism includes multiple roller groups, a third drive assembly 34, and a transmission assembly. The multiple roller groups are spaced apart in the conveying direction. Each roller group includes two conveying rollers 31. The two ends of the conveying rollers 31 are rotatably connected to the mounting plate 11. Two synchronous pulleys 311 are coaxially provided at one end of the conveying rollers 31, and the synchronous pulleys 311 are fixedly connected to the conveying rollers 31. The third drive assembly 34 is connected to the mounting plate 11, and its power output end is connected to at least one conveying roller 31. As shown in Figures 1 and 2, the transmission assembly includes multiple first synchronous belts 32 and multiple second synchronous belts 33. The first synchronous belts 32 are connected to one synchronous pulley 311 at one end of the two conveying rollers 31 in the roller group, and the second synchronous belts 33 are connected to the other synchronous pulley 311 at one end of the two conveying rollers 31 in two adjacent roller groups to ensure the stability of power transmission.

[0072] Specifically, the third drive component 34 is an existing motor component, consisting of a motor and a reducer, or it can be a pneumatic motor or a hydraulic motor, etc., that can drive the conveyor roller 31 to rotate continuously.

[0073] It should be noted that the conveyor roller 31 is an existing roller with a cylindrical body in the middle and rotating shafts at both ends, which rotate in conjunction with the mounting plate 11. The synchronous wheel 311 is fixedly connected to the rotating shaft at the end of the conveyor roller 31.

[0074] like Figure 6As shown, the conveying mechanism also includes multiple first rubber rings 41 and several second rubber rings 42. The first rubber rings 41 are spaced apart on the conveying rollers 31, and each first rubber ring 41 spans at least two adjacent conveying rollers 31 to increase the friction between the material and the conveyor, so as to generate sufficient traction force to drive the material forward when conveying the material. Several second rubber rings 42 are spaced apart along the axial direction of the conveying rollers 31, and the two ends of the second rubber rings 42 are respectively fitted on the first and last conveying rollers 31 along the conveying direction to effectively support the material and prevent the material from getting stuck in the gap between the conveying rollers 31, which would cause the material to jam.

[0075] Specifically, two conveying rollers 31 are arranged as a group, and two or more first rubber rings 41 are arranged axially at intervals on each conveying roller 31.

[0076] Several arc-shaped grooves are provided on the conveyor roller 31. The first rubber ring 41 and the second rubber ring 42 are both fitted into the arc-shaped grooves to effectively limit the position of the first rubber ring 41 and the second rubber ring 42 on the conveyor roller 31 and prevent them from moving around randomly.

[0077] The flipping assembly includes a support tube 13 and a first drive assembly 14. The support tube 13 is connected to two mounting plates 11. Both ends of the support tube 13 are adapted to rotate with the housing 70 of the unpacking machine. The power output end of the first drive assembly 14 is connected to the support tube 13 to drive the support tube 13 to rotate.

[0078] Specifically, the first drive assembly 14 is a device such as an existing motor assembly, rotary cylinder, or rotary hydraulic cylinder that can drive the support tube 13 to rotate at a certain angle. The support tube 13 is connected to the sealing box 12, and the air passage and wires pass through the support tube 13 into the sealing box 12 without being exposed inside the housing 70. Therefore, the air passage and wires can be protected, and at the same time, the dead corners for hygiene are reduced.

[0079] like Figure 7 and Figure 9 As shown, the second drive assembly includes multiple rocker arms 53, connecting rods 54, and a second drive element 56. Each rocker arm 53 corresponds to a shaft. One end of each rocker arm 53 is connected to the shaft, and the other end is connected to the connecting rod 54. The second drive element 56 is rotatably connected to the mounting plate 11, and the power output end is rotatably connected to the connecting rod 54 or the rocker arm 53.

[0080] The second driving element 56 is a cylinder, but it can also be a hydraulic cylinder, an electric actuator, or other power element. The power output end is hinged to the end of the connecting rod 54 or one of the rocker arms 53 to drive all the hooks to move synchronously.

[0081] like Figure 4As shown, the cutting assembly is located below the conveying assembly and includes a cutting blade 81 and a blade drive assembly 82. The blade drive assembly 82 is connected to the housing 70, and its power output end is connected to the cutting blade 81 to drive the cutting blade 81 to rotate and cut open the bottom of the material bag. The blade drive assembly 82 is a device that can drive the cutting blade 81 to rotate, such as a rotary cylinder, a motor with a reducer, or a rotary hydraulic cylinder.

[0082] like Figure 1 and Figure 4 As shown, the unpacking machine also includes a bag discharge assembly. The bottom of the housing 70 is provided with a bag discharge chamber 72, and the end of the bag discharge chamber 72 is provided with a bag discharge opening. The bag discharge assembly includes a receiving assembly, an auger 91, and a fourth drive assembly 92. The receiving assembly is located between the conveying assembly and the bag discharge chamber 72 and is used to guide empty bags on the conveying assembly into the bag discharge chamber 72. The auger 91 is located in the bag discharge chamber 72 and is rotatably connected to the housing 70. The fourth drive assembly 92 is connected to the housing 70 and its power output end is connected to the auger 91 to drive the auger 91 to rotate and discharge the material bags in the bag discharge chamber 72.

[0083] The receiving assembly includes a second shaft 93, a receiving plate 94, and a fifth drive assembly 95. The second shaft 93 is rotatably engaged with the housing 70. The receiving plate 94 is connected to the second shaft 93 and rotates with the second shaft 93. The fifth drive assembly 95 is connected to the housing 70, and its power output end is connected to the second shaft 93 to drive the second shaft 93 to rotate, so that the receiving plate 94 approaches the end of the horizontal conveying assembly to receive and guide the material bag into the bag discharge chamber 72.

[0084] The fourth drive assembly 92 is a combination of a motor and a reducer, and the fifth drive assembly 95 is a rotary cylinder, a motor-driven rocker mechanism, a motor equipped with a reducer, etc.

[0085] The operation process of the unpacking machine is as follows:

[0086] Place the material onto the temporary storage conveyor assembly 102, ensuring that at least one bag of material is stored on the temporary storage conveyor assembly 102; control the operation of two drive elements to drive the two centering plates 113 to move towards each other, pushing the material to the center.

[0087] The control door opening assembly opens the feed inlet; the control temporary conveying assembly 102 conveys the material forward until a bag of material is completely inside the feed inlet; then, the control door opening assembly closes the feed inlet.

[0088] The material bag containing the material enters the conveying assembly through the feed inlet and is conveyed forward by the conveying assembly. After reaching the preset position, the second drive element 56 drives the hook to rotate upward and hook the material bag; the first drive assembly 14 drives the support tube 13 to rotate, causing the conveying assembly to rotate downward.

[0089] After being flipped into place, the tool drive assembly 82 drives the cutting tool 81 to rotate, cutting the material bag open and allowing the material inside to fall into the hopper 71 below. The bottom of the hopper 71 is the discharge port.
