Description

Technical Field

[0001] This application relates to the field of bagging machine technology, specifically to a bagging and bundling machine. Background Technology

[0002] Vertical filling packaging machines are used to fill vertical bags with contents, continuously producing sealed film packaging bags. After filling, the bags are transferred and sealed using a conveyor mechanism. Existing conveyor mechanisms mostly use bottom-supported turntables or belt conveyors. For packaging bags that cannot stand upright, a tilting device is usually required on the conveyor mechanism, making the conveyor mechanism structure complex. Furthermore, the bag feeding mechanism and the conveying mechanism are usually set up independently, requiring different power systems for driving, which makes the overall structure of the device complex and large in size. Utility Model Content

[0003] In view of this, this application provides a bagging and sealing machine to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A bagging and sealing machine includes a frame and an electrical control box, which further includes:

[0006] A bag supply mechanism is used to supply packaging bags;

[0007] The bag-pulling mechanism includes bag-pulling jaws, which clamp the upper part of the packaging bag, causing the packaging bag to automatically enter a vertical state.

[0008] The bag transfer mechanism includes a lower bag clamping mechanism and an upper bag clamping mechanism that can move synchronously. The upper bag clamping mechanism and the lower bag clamping mechanism are used to clamp the upper and lower parts of the packaging bag that has entered the vertical state.

[0009] The bag opening mechanism is used to open the top opening of the bag after it is transferred to the bag transfer mechanism. This makes it easier to fill the bag.

[0010] The bag clamping mechanism clamps the bag after filling. After clamping, the lower bag clamping mechanism opens, and the lower and upper bag clamping mechanisms move synchronously to the bag picking point. When the upper bag clamping mechanism clamps, it simultaneously clamps the upper part of both the unused bag and the clamped bag. When the unused bag moves to the bag opening mechanism, the clamped bag moves to the sealing mechanism for sealing. When the upper bag clamping mechanism opens again, the sealed bag falls automatically.

[0011] Furthermore, the bag clamping mechanism is also equipped with an air extraction component for extracting air from the bagged packaging bag, and the air extraction pipe of the air extraction component can be raised and lowered.

[0012] Furthermore, the bag supply mechanism includes a bag storage compartment, in which stacked sheet-like packaging bags are placed, and an adsorption-type bag separating component is provided at the bag outlet of the bag storage compartment.

[0013] Furthermore, the storage compartment consists of multiple adjustable compartment enclosures.

[0014] Furthermore, the bag-pulling mechanism also includes a rotatable rocker arm, and the bag-pulling grippers are mounted on the rocker arm via a gripper drive mechanism.

[0015] Furthermore, the bag-opening mechanism includes two sets of opposing second suction cup assemblies, which are connected to the corresponding bag-opening linear drive mechanism.

[0016] Furthermore, the bag clamping mechanism includes a liftable central bag clamping assembly and side bag clamping assemblies located on both sides of the central bag clamping assembly. The opening direction of the side bag clamping assemblies is consistent with the opening direction of the central bag clamping assembly, and the distance between the two side bag clamping assemblies is adjustable.

[0017] Furthermore, the middle-position bag clamping assembly includes a liftable lifting base and a pair of middle-position bag clamping lips hinged on the lifting base. The pair of middle-position bag clamping lips are synchronized by a gear pair, and the corresponding middle-position bag clamping lips are connected to the bag clamping opening drive mechanism.

[0018] Furthermore, the side-position bag clamping assembly includes two side-position bag clamping arms, which are linked and controlled by a bag clamping arm synchronous drive mechanism.

[0019] Furthermore, a material receiving and guiding trough is provided below the sealing mechanism.

[0020] As can be seen from the above technical solution, the advantages of this utility model are:

[0021] 1. In this application, the reciprocating movement of the bag transfer mechanism enables the bag to pass sequentially through the bag opening mechanism and the sealing mechanism. The bag opening mechanism completes the bag filling, and the sealing mechanism completes the sealing process. Compared with the prior art, there is no need to use a separate transfer mechanism between the bag opening mechanism and the sealing mechanism, which simplifies the structure. Moreover, the bag is always suspended during the transfer process and will not tip over.

[0022] 2. The size of the storage bag compartment in this application is adjustable, and the distance between the two side bag clamping components is adjustable, thus meeting the needs of packaging bags of various specifications.

[0023] 3. This application utilizes a bag feeding mechanism, a bag pulling mechanism, a bag transferring mechanism, a bag opening mechanism, a bag clamping mechanism, and a sealing mechanism to work together, enabling continuous automatic operation with high efficiency. Attached Figure Description

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0035] refer to Figures 1 to 8 ,like Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a bagging and sealing machine, including a frame 1, an electrical control box 2, and a bag feeding mechanism 3, a bag pulling mechanism 4, a bag transferring mechanism 5, a bag opening mechanism 6, a bag clamping mechanism 7, and a sealing mechanism 8, all mounted on the frame 1. The bag feeding mechanism 3 is used to supply packaging bags 100. The bag feeding mechanism 3 is in an externally visible state, which facilitates timely observation of the storage status of the packaging bags so that materials can be replenished in a timely manner. The bag pulling mechanism 4 includes a bag pulling claw 45, which clamps the upper part of the packaging bag 100, so that the packaging bag 100 automatically enters a vertical state. The bag transferring mechanism 5 includes a lower bag clamping mechanism 52 and an upper bag clamping mechanism 53 that can move synchronously. The upper bag clamping mechanism 53 and the lower bag clamping mechanism 52 are used to clamp the upper and lower parts of the packaging bag 100 that has entered the vertical state, so that the packaging bag 100 automatically enters a vertical state. The packaging bag 100 is transferred from the bag-pulling mechanism 4 to the bag-shifting mechanism 5. After the packaging bag 100 is transferred to the bag-opening mechanism 6 by the bag-shifting mechanism 5, the bag-opening mechanism 6 opens the top opening of the packaging bag 100 to facilitate filling. After filling, the packaging bag 100 is first clamped by the bag-clamping mechanism 7. After clamping, the lower bag-clamping mechanism 52 opens, and the lower bag-clamping mechanism 52 and the upper bag-clamping mechanism 53 move to the bag-removing position simultaneously. When the upper bag-clamping mechanism 53 clamps, it simultaneously clamps the top of the unused packaging bag 100 and the clamped packaging bag 100. When the unused packaging bag 100 moves to the bag-opening mechanism 6, the clamped packaging bag 100 moves to the sealing mechanism 8 for sealing. When the upper bag-clamping mechanism 53 opens again, the sealed packaging bag 100 falls automatically.

[0036] like Figure 2 As shown in this embodiment, a material receiving and guiding groove 9 is provided below the sealing mechanism 8. After the sealed packaging bag 100 falls, it falls and is transferred along the material receiving and guiding groove 9, which facilitates continuous production without stopping the machine.

[0037] like Figure 4 and Figure 5 As shown, the bag supply mechanism 3 can supply pre-made finished sheet-like packaging bags 100 or use bag rolls to produce sheet-like packaging bags 100 in real time. When it is necessary to use bag rolls for packaging bag processing, the specific structure of the bag supply mechanism 3 can refer to the bag making machine in the prior art, such as CN209794717U.

[0038] In this embodiment, preferably, the bag supply mechanism 3 is used to supply finished sheet-like packaging bags 100. The bag supply mechanism 3 includes a bag storage compartment, in which the sheet-like packaging bags 100 are stacked and placed in the bag storage compartment. An adsorption-type bag separating component is provided at the bag outlet of the bag storage compartment. The adsorption-type bag separating component is used to suck the packaging bags 100 out of the bag storage compartment for sheet separation.

[0039] Specifically, such as Figure 4As shown, the bag feeding mechanism 3 also includes a bag feeding base 31 connected to the frame 1 and a bag feeding lifting frame 32 that can be raised and lowered and mounted on the bag feeding base 31. The bag feeding lifting frame 32 is provided with multiple adjustable bag storage compartment enclosure frames 35. The bag storage compartment is composed of multiple adjustable bag storage compartment enclosure frames 35, which can be used to accommodate packaging bags 100 of different specifications. The bag storage compartment enclosure frames 35 are used to guide and limit the bag stack by contacting the side of the packaging bag 100. The bag feeding lifting frame 32 is provided with hollow holes corresponding to the positions of the cavities formed by the bag storage compartment enclosure frames 35. The section near the bag outlet of part 5 is provided with a material blocking structure 36, which is used to form a certain narrowing structure at the bag outlet to prevent the packaging bag 100 from automatically running out of the storage bag bin, so as to make the bag separating action reliable. The adsorption-type bag separating assembly includes a first suction cup assembly 34 and a bag picking linear drive mechanism 33 connected to the first suction cup assembly 34. The bag picking linear drive mechanism 33 controls the first suction cup assembly 34 to move closer to or away from the bag outlet to complete the bag separating. The bag picking linear drive mechanism 33 is preferably a cylinder, but it can also be replaced by a linear motor, a lead screw and nut, or a gear and rack structure.

[0040] In this application, the storage bag bin can be set vertically or horizontally. When the storage bag bin is set vertically, the outlet of the bag is preferably located at the bottom, so that the movement stroke of the adsorption-type bag separating component is stable and it is convenient to replenish the packaging bag 100 in the storage bag bin. When the storage bag bin is set horizontally, the replenishment port of the storage bag bin is provided with a pressing mechanism that pushes the bag stack toward the outlet of the bag, so that the packaging bag 100 is in reliable contact with the material blocking structure 36, thereby making the bag separating action stable and reliable.

[0041] like Figure 4 and Figure 5 As shown, the bag-pulling mechanism 4 also includes a rotatable rocker arm 41, and the bag-pulling claw 45 is mounted on the rocker arm 41 via a claw drive mechanism 44.

[0042] Specifically, when the storage bag bin is vertically positioned and the bag outlet is located at the bottom, the packaging bag 100 separated from the storage bag bin is horizontal. The bag-pulling claw 45 is perpendicular to the swing rod 41. When the swing rod 41 returns to its horizontal position, the bag-pulling claw 45 is located below the swing rod 41. Rotating the swing rod 41 by 90° allows the bag-pulling claw 45 to move to the packaging bag 100 located at the adsorption-type bag-splitting assembly. The bag-pulling claw 45 then clamps and transfers the bag opening end of the packaging bag 100. The bag compartment is set horizontally, and the bag-pulling claw 45 is perpendicular to the swing arm 41. The swing arm 41 can be rotated 180° to move the bag-pulling claw 45 to the packaging bag 100 located at the adsorption-type bag-separating assembly. When the bag-pulling claw 45 is clamping the bag, it is located above the swing arm 41. When the bag is feeding, the bag-pulling claw 45 is located below the swing arm 41. The claw drive mechanism 44 is preferably a claw cylinder, which makes the clamping arm of the bag-pulling claw 45 swing open and close. The bag-pulling claw 45 can also use the clamping arm movement to control the opening and closing of the clamping mouth.

[0043] In this application, the swing arm 41 is hinged to the bag base 48 via the rotating shaft 43. The bag base 48 is connected to the frame 1. The rotating shaft 43 is connected to the swing drive mechanism 42 to control the swing arm 41 to rotate in both directions. The commonly used swing drive mechanism 42 is a motor.

[0044] In this embodiment, as Figure 4 As shown, the swing arm 41 swings repeatedly within a 90° range. The swing drive mechanism 42 includes a swing arm 422 connected to the other end of the rotating shaft 43 and a bag-pulling linear drive mechanism 421 connected to the swing arm 422. The bag-pulling linear drive mechanism 421 is hinged to avoid jamming. The bag-pulling linear drive mechanism 421 is preferably a cylinder. When the swing arm 41 returns to the horizontal position to feed the bag, the frame 1 is also provided with a first limiting mechanism 46 and a first position detection device 47 that can resist the swing arm 41. The first limiting mechanism 46 is used to limit the stopping position of the swing arm 41 to ensure high bag feeding accuracy. When picking up the bag, the upper bag clamping mechanism 53 is located below the bag-pulling claw 45. The first position detection device 47 is used to determine whether the swing arm 41 has moved to the correct position. The vertical position limit of the swing arm 41 can be blocked by the bag feeding lifting frame 32.

[0045] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the bag transfer mechanism 5 also includes a bag transfer sliding seat 51 that is slidably mounted on the frame 1 via a guide rail. The lower bag clamping mechanism 52 and the upper bag clamping mechanism 53 are both mounted on the bag transfer sliding seat 51 to achieve synchronous movement. The bag transfer sliding seat 51 is connected to the moving drive mechanism 54. The lower bag clamping mechanism 52 includes two sets of cylinders arranged opposite each other and lower clamps mounted on the movable ends of the cylinders. By controlling the pair of lower clamps to move away from or closer to each other, the lower part of the packaging bag 100 is released or clamped. The upper bag clamping mechanism 53 includes two T-shaped arms 531 that work together. The main arm of the T-shaped arm 531 forms the upper clamp. The side arm of the T-shaped arm 531 is connected to the upper bag clamping opening and closing control mechanism, and the lower clamp is located on the side of the side arm of the T-shaped arm 531 that is closer to the bag pulling mechanism 4.

[0046] In this application, the upper bag opening and closing control mechanism can be a synchronous belt structure or a chain structure, and the two T-shaped arms 531 are respectively installed on both sides of the transmission wheel; the upper bag opening and closing control mechanism can also be a cylinder; preferably, in this application, the upper bag opening and closing control mechanism includes a drive gear and two racks that mesh with the drive gear and move in opposite directions. The two racks move in opposite directions or towards each other to control the two T-shaped arms 53 to move away from or towards each other, thereby controlling the opening and closing of the upper clamping opening. The bag transfer sliding seat 51 is provided with a second limiting mechanism that can abut against the corresponding rack, wherein one rack is connected to the cylinder.

[0047] In this application, the moving drive mechanism 54 can be a synchronous belt structure or a chain structure, and the bag transfer slide seat 51 is connected to the transmission belt structure; the moving drive mechanism 54 can also be a cylinder; the moving drive mechanism 54 can also be a gear and rack meshing structure, and the bag transfer slide seat 51 is connected to the rack.

[0048] In this application, wear-resistant and anti-slip pads may be provided on the clamping surfaces of the lower and upper chucks.

[0049] like Figure 2 , Figure 3 and Figure 6 As shown, the bag-opening mechanism 6 includes two sets of opposing second suction cup assemblies 61. Each second suction cup assembly 61 is connected to a corresponding bag-opening linear drive mechanism 62, which is connected to the frame 1. The second suction cup assemblies 61 are located above the upper bag-clamping mechanism 53. The bag-opening linear drive mechanism 62 is preferably a cylinder. The second suction cup assemblies 61 adhere to the corresponding sides of the packaging bag 100, and the bag-opening linear drive mechanism 62 controls the interaction of the two sets of second suction cup assemblies 61 to open the bag opening.

[0050] like Figure 2 , Figure 3 , Figure 6 and Figure 8 As shown, the bag clamping mechanism 7 includes a liftable central bag clamping assembly and side bag clamping assemblies 75 located on both sides of the central bag clamping assembly. The opening direction of the side bag clamping assemblies 75 is consistent with the opening direction of the central bag clamping assembly. The two side bag clamping assemblies 75 are connected to the bag clamping width adjustment mechanism 77 to realize the adjustable distance between the two side bag clamping assemblies 75.

[0051] Specifically, the middle-position bag clamping assembly includes a bag clamping lifting drive mechanism 72 fixedly installed on the frame 1, a lifting seat 71 connected to the movable end of the bag clamping lifting drive mechanism 72, and a pair of middle-position bag clamping lips 73 hinged on the lifting seat 71. The pair of middle-position bag clamping lips 73 achieve synchronous linkage through a gear pair. The corresponding middle-position bag clamping lips 73 are connected to the bag clamping mouth drive mechanism 74. When the pair of middle-position bag clamping lips 73 are in the clamping state, a cavity with a closed bottom and an open top is formed between the pair of middle-position bag clamping lips 73. The middle-position bag clamping lips 73 located on the outer side will play a guiding role when filling materials. The bag clamping mouth drive mechanism 74 is preferably a hinged cylinder.

[0052] In this application, the bag clamping width adjustment mechanism 77 may include a drive gear and two racks meshing with the drive gear with opposite movements. The two racks move in opposite or opposite directions to control the two sets of side bag clamping assemblies 75 to move away from or towards each other, thereby controlling the distance between the two sets of side bag clamping assemblies 75 to accommodate packaging bags 100 of different widths. Preferably, in this application, the bag clamping width adjustment mechanism 77 is a synchronous belt mechanism, with the two sets of side bag clamping assemblies 75 located on both sides of the synchronous belt pulley. The distance between the two sets of side bag clamping assemblies 75 is controlled by the opposite running directions of the synchronous belts on both sides of the synchronous belt pulley. The synchronous belt mechanism may also be replaced by a sprocket drive mechanism.

[0053] In this application, the side-position bag clamping assembly 75 includes two side-position bag clamping arms 752, and the two side-position bag clamping arms 752 are linked and controlled by the bag clamping arm synchronous drive mechanism 751.

[0054] Specifically, the bag clamping arm synchronous drive mechanism 751 includes a gear and two racks with opposite directions of movement that mesh with the gear. The corresponding racks are connected to the cylinder. The side bag clamping arm 752 near the cylinder is straight, and the side bag clamping arm 752 away from the cylinder extends over the packaging bag 100 in an L-shape, making the control mechanism structure compact.

[0055] In this application, the bag clamping mechanism 7 is also provided with a suction component 10 for suctioning the bag 100 after bagging. The suction pipe of the suction component 10 is liftable and is located between the middle bag clamping component 75 and the corresponding side bag clamping component 75.

[0056] In this application, the pair of heat-sealing blades 81 of the sealing mechanism 8 are located above the upper bag clamping mechanism 53, ensuring that the packaging bag 100 remains clamped and fixed by the upper bag clamping mechanism 53 during sealing, thus making the sealing reliable.

[0057] like Figure 1 As shown in this application, the frame 1 is also provided with an upper protective flap 20, a first side protective flap 30 and a second side protective flap 40 hinged to the frame 1. The upper protective flap 20 is located above the sealing mechanism 8, and the first side protective flap 30 is located above the material receiving guide trough 9. The arrangement of the first side protective flap 30 and the second side protective flap 40 facilitates the inspection and maintenance of the bag clamping mechanism 7 and the bag transferring mechanism 5.

[0058] During operation, the first suction cup assembly 34 first sucks out a packaging bag 100 from the storage compartment. Then, the bag pulling mechanism 4 adjusts the orientation of the packaging bag 100. When the bag moving mechanism 5 approaches the bag pulling mechanism 4, the lower bag clamping mechanism 52 and the upper bag clamping mechanism 53 are in the open state. The forward extension arm of the upper clamp and the lower clamp extend to below the bag pulling claw 45. After moving into position, the lower bag clamping mechanism 52 and the upper bag clamping mechanism 53 close to clamp the lower and upper parts of the packaging bag 100 simultaneously. At the same time, the packaging bag 100 clamped by the bag opening mechanism 7 is also clamped by the rear extension arm of the upper clamp. The middle bag clamping assembly of the bag opening mechanism 7 moves upward to reserve working space for the bag opening mechanism 6. When the bag moving mechanism 5 moves away from the bag pulling mechanism 4, the packaging bag 100 clamped and fixed on the rear extension arm of the upper bag clamping mechanism 53... The bag 100 is sent to the sealing mechanism 8. After the bag is sealed, the upper bag clamping mechanism 53 opens, and the material package inside the sealing mechanism 8 falls automatically. At the same time, the bag opening mechanism 6 is used to open the new bag that has been moved back to the bag opening clamping mechanism 7. Then, the contents are filled into the opened packaging bag 100. After filling, the bag opening mechanism 6 and the upper bag clamping mechanism 53 cooperate to close the upper opening of the filled packaging bag 100. The second suction cup assembly 61 of the bag opening mechanism 6 retracts, the middle bag clamping assembly descends and closes with the two side bag clamping assemblies 75 to clamp the filled packaging bag 100 fixed on the upper bag clamping mechanism 53. Then, the lower bag clamping mechanism 52 and the upper bag clamping mechanism 53 open and move towards the bag pulling mechanism 4 to repeat the cycle, so that the bagging and bagging work can be automated.

[0059] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to the embodiments of this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
