Description

Technical Field

[0001] This invention relates to the field of packaging mechanism technology, and in particular to a bagging and sealing packaging device. Background Technology

[0002] For materials that require packaging bags, the packaging process involves opening the bag, placing the material inside, and then sealing it to complete the packaging. Currently, the most common packaging method is traditional manual packaging, where people manually open the bags, fill them with material, and then seal the opening using a sealing machine. This method is inefficient and has high labor costs.

[0003] Although there are existing technologies that use packaging equipment for packaging, such as the packaging bag sealing equipment in patent number CN202111464047.X, which is used for opening, filling and sealing packaging bags, the entire equipment has many parts, is inconvenient to assemble and install, and has a complicated mechanism, making it difficult to ensure the sealing accuracy of the product. Summary of the Invention

[0004] The technical problem solved by this invention is to provide a bag-sealing packaging device with a simple structure that can quickly and conveniently seal the opening of packaging bags, thereby improving work efficiency, reducing manual operation, and increasing the degree of automation.

[0005] To solve the above-mentioned technical problems, the present invention provides a bag sealing packaging device, including a packaging frame, a bag supporting mechanism for opening the packaging bag and a bag clamping mechanism for holding the packaging bag. A sealing device arranged in the Z-axis direction is installed on the packaging frame, and the bag supporting mechanism and the bag clamping mechanism are respectively located on both sides of the sealing device in the X-axis direction.

[0006] The sealing device includes an upper sealing component and a lower sealing component that are directly opposite each other, and they move back and forth synchronously in the Z-axis direction to seal the opening of the packaging bag at the top and bottom of the packaging bag.

[0007] The bag-supporting mechanism includes two symmetrically arranged left and right supporting arms along the Y-axis. The left and right supporting arms are arranged correspondingly and move in opposite directions synchronously in the Y-axis direction to open the opening of the packaging bag to a flat state.

[0008] The bag-supporting mechanism further includes a sliding seat for mounting the left and right supporting arms, and a first driving unit for driving the sliding seat to move along the X-axis. The left and right supporting arms move simultaneously into the opening of the packaging bag along the X-axis via the first driving unit.

[0009] Furthermore, the left and right sides of the packaging frame are respectively provided with a pulley group that moves along the Z-axis direction. Both pulley groups include a belt that reciprocates in the Z-axis direction. The two ends of the upper sealing member and the lower sealing member are respectively fixed on the belts of the two pulley groups.

[0010] On the corresponding surfaces of the upper and lower sealing components, corrugated pressing parts are provided that cooperate with each other, and the pressing parts extend along the Y-axis direction.

[0011] Furthermore, the packaging frame is also provided with a synchronous connecting shaft for connecting the two pulley sets to rotate synchronously, and one end of the synchronous connecting shaft is connected to the main drive motor.

[0012] Furthermore, the expanding sliding seat includes a first base and a first slide rail extending along the Y-axis on the first base. Two first sliders are slidably connected on the first slide rail. The two first sliders are respectively fixedly mounted on the left expanding arm and the right expanding arm, and the two first sliders move synchronously in opposite directions on the first slide rail.

[0013] Furthermore, both the left and right expansion arms include strip-shaped expansion portions corresponding to the upper and lower sealing components. The strip-shaped expansion portions are horizontally arranged along the X-axis and extend into the opening of the packaging bag through the first drive unit.

[0014] Furthermore, the bag clamping mechanism includes two symmetrically arranged left and right clamps along the Y-axis direction. The left clamp corresponds to the left spreading arm in the X-axis direction, and the right clamp corresponds to the right spreading arm in the X-axis direction.

[0015] Furthermore, the left clamp and the right clamp are located on both sides of the packaging bag and are close to the sealing device;

[0016] Both the left and right clamps include a gripper cylinder, and the gripping part of the gripper cylinder is provided with two corresponding upper and lower grippers for gripping the upper and lower sides of the packaging bag.

[0017] Furthermore, the bag clamping mechanism also includes a bag clamping slide seat and a second drive unit for driving the bag clamping slide seat to move along the X-axis direction;

[0018] The bag clamping sliding seat includes a second base and a second slide rail extending along the Y-axis on the second base. Two second sliders are slidably connected on the second slide rail. The two second sliders are respectively fixedly mounted on the left clamp and the right clamp, and the two second sliders move synchronously in opposite directions on the second slide rail.

[0019] Furthermore, both the first drive unit and the second drive unit include a fixed base and an X-axis slide rail mounted on the fixed base. The fixed base is also equipped with an X-axis lead screw unit and a drive motor, and the drive motor drives the nut seat of the X-axis lead screw unit to move along the X-axis direction.

[0020] Furthermore, connectors are installed on both of the second sliders, and the upper ends of the two connectors are respectively connected to the left clamp and the right clamp.

[0021] Compared with related technologies, the present invention has the following beneficial effects:

[0022] This invention provides a bag-sealing packaging device with a simple structure, mostly symmetrical parts, easy assembly, and low installation difficulty, ensuring accuracy. The left and right supporting arms of the bag-supporting mechanism are inserted into the opening of the packaging bag and move to both sides of the opening, flattening it and facilitating a smooth seal. Simultaneously, the left and right clamps of the bag-clamping mechanism clamp the sides of the packaging bag, ensuring stability during the sealing process and preventing the bag from falling off. Finally, the upper and lower sealing components of the sealing device press firmly on the upper and lower sides of the bag opening to complete the seal. This results in a good sealing effect, ensuring a smooth seal and packaging quality. It eliminates the need for manual operation, increasing automation and work efficiency.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a bag sealing packaging device includes a packaging frame 1, a bag-opening mechanism 2 for opening the packaging bag (not shown in the figure), and a bag-clamping mechanism 3 for clamping the packaging bag. A sealing device 4 arranged in the Z-axis direction is installed on the packaging frame 1. The bag-opening mechanism 2 and the bag-clamping mechanism 3 are respectively located on both sides of the sealing device 4 in the X-axis direction.

[0034] The sealing device 4 includes an upper sealing member 41 and a lower sealing member 42 that are directly opposite each other and move synchronously in opposite directions along the Z-axis, thereby sealing the opening of the packaging bag from both the top and bottom. After the packaging bag is filled with materials, it is conveyed to the middle of the sealing device 4 via a conveyor production line (not shown in the figure). The upper sealing member 41 is always located above the packaging bag, and the lower sealing member 42 is always located below the packaging bag. By moving the upper sealing member 41 and the lower sealing member 42 simultaneously and moving towards the opening of the packaging bag located between them, it is convenient to seal the opening of the packaging bag.

[0035] The bag-supporting mechanism 2 includes two symmetrically arranged left supporting arms 21 and right supporting arms 22 along the Y-axis. The left supporting arms 21 and right supporting arms 22 are arranged correspondingly and move in opposite directions synchronously in the Y-axis direction to open the opening of the packaging bag to a flat state.

[0036] In addition, the bag-supporting mechanism 2 also includes a supporting sliding seat 23 for mounting the left supporting arm 21 and the right supporting arm 22, and a first driving unit 5 for driving the supporting sliding seat 23 to move along the X-axis direction. The left supporting arm 21 and the right supporting arm 22 are simultaneously moved into the opening of the packaging bag along the X-axis direction by the first driving unit 5.

[0037] Specifically, the sliding support 23 includes a first base 6 and a first slide rail 61 extending along the Y-axis on the first base 6. Two first sliders 62 are slidably connected on the first slide rail 61. The two first sliders 62 are respectively fixedly mounted on the left opening arm 21 and the right opening arm 22, and the two first sliders 62 move synchronously in opposite directions on the first slide rail 61. The two first sliders 62 are both mounted on a threaded rod with opposite threads. The two first sliders 62 are respectively on the opposite threaded sections of the threaded rod. The threaded rod is driven by a motor to rotate, so that the threaded rod rotates. The two first sliders 62 move simultaneously on the threaded rod and move closer to or away from each other by the forward and reverse rotation of the threaded rod, so that the left opening arm 21 and the right opening arm 22 move closer to or away from each other.

[0038] Since the opening of the packaging bag is irregular after the materials are packaged, it is not easy to seal. The first driving unit 5 drives the left opening arm 21 and the right opening arm 22 into the packaging bag. The left opening arm 21 and the right opening arm 22 move to both sides inside the packaging bag at the same time, flattening the irregular opening of the packaging bag. After the opening of the packaging bag is flattened, it can be parallel and correspond to the upper sealing part 41 above and the lower sealing part 42 below, which facilitates the sealing of the sealing device 4, ensures the sealing effect of the packaging bag, and the seal is flat and has good sealing performance.

[0039] To ensure the opening of the packaging bag is properly opened and to facilitate a smooth seal after the sealing device 4 opens the packaging bag, preventing wrinkles, both the left opening arm 21 and the right opening arm 22 include a strip-shaped opening portion 200 corresponding to the upper sealing member 41 and the lower sealing member 42. The strip-shaped opening portion 200 is horizontally arranged along the X-axis and extends into the opening of the packaging bag through the first driving unit 5.

[0040] The packaging bag is located between the upper sealing member 41 and the lower sealing member 42, with its opening facing the bag supporting mechanism 2. The strip-shaped supporting parts 200 on the left supporting arm 21 and the right supporting arm 22 move inside the opening of the packaging bag and then move to the left and right sides at the same time, thereby opening and flattening the opening of the packaging bag to facilitate the sealing device 4 to seal it.

[0041] For example Figure 2 and Figure 3 As shown, during the sealing process of each packaging bag, the upper sealing component 41 and the lower sealing component 42 need to simultaneously seal the upper and lower sides of the packaging bag opening, and after sealing, they need to simultaneously deviate from the packaging bag. Therefore, the upper sealing component 41 and the lower sealing component 42 need to move simultaneously. For this purpose, the left and right sides of the packaging frame 1 are respectively provided with a pulley group 7 that moves along the Z-axis. Both of the pulley groups 7 include a belt 71 that reciprocates in the Z-axis direction. The two ends of the upper sealing component 41 and the lower sealing component 42 are respectively fixed on the belt 71 of the two pulley groups 7 and move synchronously with the belt 71.

[0042] As the belt 71 pulley group 7 rotates in the forward or reverse direction, the belt 71 moves synchronously in the forward or reverse direction, allowing the upper sealing member 41 and the lower sealing member 42 to approach or deviate from each other. During sealing, the upper sealing member 41 and the lower sealing member 42 approach each other until they fit the packaging bag. After sealing, the upper sealing member 41 and the lower sealing member 42 move in the opposite direction via the belt 71, while simultaneously deviating from the opening of the packaging bag.

[0043] In this embodiment, the packaging frame 1 is also provided with a synchronous connecting shaft 72 for connecting the two belt 71 pulley sets 7 to rotate synchronously, and one end of the synchronous connecting shaft 72 is connected to the main drive motor 73.

[0044] On the corresponding surfaces of the upper sealing member 41 and the lower sealing member 42, corrugated pressing parts 400 are provided that cooperate with each other. The pressing parts 400 extend along the Y-axis direction, that is, in the same direction as the opening of the packaging bag. The corrugated pressing parts 400 on the upper sealing member 41 and the lower sealing member 42 are offset and pressed against the upper and lower sides of the opening of the packaging bag, facilitating a complete seal of the opening. The sealing of the packaging bag by the upper sealing member 41 and the lower sealing member 42 is a conventional technical means used in the art and is not the inventive point of this application, and will not be described further here.

[0045] For example Figure 5As shown, to ensure the stability of the packaging bag's opening during sealing, a bag clamping mechanism 3 clamps the opening to prevent it from shifting. Specifically, the bag clamping mechanism 3 includes two symmetrically arranged clamps, a left clamp 31 and a right clamp 32, along the Y-axis. The left clamp 31 corresponds to the left opening arm 21 in the X-axis direction, and the right clamp 32 corresponds to the right opening arm 22 in the X-axis direction.

[0046] The left clamp 31 and the right clamp 32 are located on both sides of the packaging bag and are close to the sealing device 4, which facilitates clamping the opening of the packaging bag.

[0047] Both the left clamp 31 and the right clamp 32 include a clamping cylinder 300. The clamping part of the clamping cylinder 300 is provided with two corresponding upper and lower clamping claws 301 for clamping the upper and lower sides of the packaging bag.

[0048] In this embodiment, in order to facilitate the flexible adjustment of the left clamp 31 and right clamp 32 on the bag clamping mechanism 3 according to the opening position of the packaging bag, the bag clamping mechanism 3 also includes a bag clamping sliding seat 8 and a second driving unit 9 for driving the bag clamping sliding seat 8 to move along the X-axis direction.

[0049] The bag-clamping sliding seat 8 includes a second base 81 and a second slide rail 82 extending along the Y-axis on the second base 81. Two second sliders 83 are slidably connected to the second slide rail 82. The two second sliders 83 are respectively fixedly mounted on the left clamp 31 and the right clamp 32, and the two second sliders 83 move synchronously in opposite directions on the second slide rail 82. Each of the two second sliders 83 is mounted on a threaded rod with opposite threads. The threaded rod is driven to rotate by a motor, causing the two second sliders 83 to move simultaneously on the threaded rod. The forward and reverse rotation of the threaded rod brings the left clamp 31 and the right clamp 32 closer together or further apart.

[0050] Both of the second sliders 83 are equipped with connectors 800. The upper ends of the two connectors 800 are respectively connected to the left clamp 31 and the right clamp 32. The left clamp 31 and the right clamp 32 are connected to the second sliders 83 through the connectors 800 and move through the second sliders 83.

[0051] For example Figure 4 and Figure 5As shown, in this embodiment, both the first drive unit 5 and the second drive unit 9 include a fixed base 100 and an X-axis slide rail 101 mounted on the fixed base 100. The fixed base 100 is also equipped with an X-axis lead screw unit 102 and a drive motor 103. The drive motor 103 drives the nut seat of the X-axis lead screw unit 102 to move along the X-axis direction.

[0052] The sliding support 23 is installed on the nut seat of the first drive unit 5 and moves along the X-axis via the lead screw unit of the first drive unit 5, so that the left supporting arm 21 and the right supporting arm 22 move toward the sealing device 4.

[0053] The bag clamping sliding seat 8 is installed on the nut seat of the second drive unit 9, and moves along the X-axis direction through the lead screw unit of the second drive unit 9, so that the left clamp 31 and the right clamp 32 move toward the sealing device 4.

[0054] In use, the packaging bag containing the materials is conveyed to the sealing device 4. The opening of the packaging bag corresponds to the bag-supporting mechanism 2. The first drive unit 5 drives the opening sliding seat 23 to move toward the opening of the packaging bag, so that the strip-shaped opening parts 200 on the left opening arm 21 and the right opening arm 22 extend into the opening of the packaging bag. Then, by the two first sliders 62 on the opening sliding seat 23 moving in opposite directions in the Y-axis direction, the left opening arm 21 and the right opening arm 22 are driven to move synchronously and move to both sides inside the opening of the packaging bag, opening the opening of the packaging bag to a flat state. After the bag is opened, they are all reset. Simultaneously, the second drive unit 9 drives the bag-clamping sliding seat 8 to move towards the packaging bag. Then, the two second sliders 83 on the bag-clamping sliding seat 8 move in opposite directions in the Y-axis direction, driving the left clamp 31 and the right clamp 32 to move synchronously, so that the left clamp 31 and the right clamp 32 correspond to the two sides of the packaging bag. The gripper cylinders 300 on the left clamp 31 and the right clamp 32 work to clamp the sides of the packaging bag, preventing the opening of the packaging bag from deviating after the bag-supporting mechanism 2 has finished supporting the bag. Finally, the main drive motor 73 drives the two belt pulley sets 7 to rotate synchronously in both directions. The belts 71 on the two belt pulley sets 7 reciprocate in the Z-axis direction, thereby causing the upper sealing member 41 and the lower sealing member 42 fixed on the belts 71 to move synchronously. When the upper sealing member 41 and the lower sealing member 42 move towards the middle of the packaging bag at the same time, they press against the packaging bag to seal the opening of the packaging bag. After sealing, they move in the opposite direction and deviate from the packaging bag. Fast sealing speed improves work efficiency; smooth sealing ensures product quality.
