Description

Technical Field

[0001] This utility model relates to the technical field of packaging, and in particular to the technical field of back-sealing packaging machines. Background Technology

[0002] Back-sealing packaging machines are a common type of automated packaging equipment, mainly used in industries such as food, cosmetics, pharmaceuticals, and agriculture. They are used to package products in various forms, including granules, powders, and liquids. The machines primarily use back-sealing to complete the packaging process and are characterized by high speed, high efficiency, and high precision, which can greatly improve production efficiency and product quality.

[0003] Existing patent CN223162110U discloses a rounded corner granule back-sealing packaging device, including a base plate, a back-sealing packaging machine mounted on the top of the base plate, a feeding port mounted on the outside of the back-sealing packaging machine, and a dispensing mechanism set on the top of the base plate. The dispensing mechanism consists of a fixing component for positioning and fixing the packaging box and an adjustment component for adjusting the positioning component. It can automatically back-seal and package materials; however, its moving bag body relies on two rollers close together, and the contact area between the rollers and the film is small, making it easy for the film and rollers to slip. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art and to propose a vertical automatic continuous bag making and packaging equipment that can stably pull the film downwards, and the film is not easy to slip when it is pulled.

[0005] To achieve the above objectives, this utility model proposes a vertical automatic continuous bag making and packaging equipment, including a frame, a film feeding mechanism, a material feeding mechanism, a vertical heat sealing mechanism, a pressing conveyor belt, and a horizontal heat sealing mechanism. The film feeding mechanism and the material feeding mechanism are installed on the frame. The material feeding mechanism includes a vertically arranged discharge pipe. A limiting cylinder is fixed on the frame and is sleeved outside the discharge pipe. The film fed by the film feeding mechanism passes through the gap between the discharge pipe and the limiting cylinder. The vertical heat sealing mechanism and the horizontal heat sealing mechanism are installed on the frame. The vertical heat sealing mechanism is located in front of the discharge pipe, and the horizontal heat sealing mechanism is located below the discharge pipe. A first pneumatic clamping claw is installed on the frame. The first pneumatic clamping claw has two grippers, and each gripper is equipped with a pressing conveyor belt. The two pressing conveyor belts are arranged opposite each other and symmetrically distributed on the left and right sides of the discharge pipe. The pressing conveyor belt and the vertical heat sealing mechanism are both lower than the limiting cylinder.

[0006] Preferably, the front side of the limiting cylinder is provided with a vertically arranged membrane-penetrating slit, through which the membrane sheet delivered by the membrane supply mechanism passes on both sides.

[0007] Preferably, the upper end of the pressing conveyor belt is higher than the lower end of the vertical heat sealing mechanism, and the lower end of the pressing conveyor belt is lower than the lower end of the vertical heat sealing mechanism.

[0008] Preferably, the vertical heat sealing mechanism consists of a second pneumatic gripper and a second heat sealing plate. The second pneumatic gripper is fixed to the frame and has two grippers. Each gripper is equipped with a vertically arranged second heat sealing plate, and the two second heat sealing plates are arranged opposite to each other.

[0009] Preferably, the horizontal heat sealing mechanism comprises a drive mechanism, a mounting frame, a first movable plate, a second movable plate, and a third heat sealing plate. A mounting frame is mounted on the frame, and the first and second movable plates are slidably mounted on the mounting frame. Both the first and second movable plates slide in the front-back direction. A horizontally arranged third heat sealing plate is mounted on each side of the first and second movable plates, with the two third heat sealing plates facing each other. A drive mechanism is mounted on the frame to drive the second and third movable plates to slide. The drive mechanism comprises a cylinder, a rotating shaft, a connecting plate, and a first connecting... The cylinder consists of a first connecting rod, a second connecting rod, and a third connecting rod. The cylinder body is fixed on the frame. A horizontally mounted rotating shaft is rotatably installed on the frame. The rotating shaft runs left and right. A first connecting rod is fixed in the middle of the rotating shaft. The end of the first connecting rod is hinged to the piston rod of the cylinder. Connecting plates are installed at both ends of the rotating shaft. A second connecting rod is hinged to the upper part of the connecting plate. The end of the second connecting rod is hinged to a first movable plate. A third connecting rod is hinged to the lower part of the connecting plate. The end of the third connecting rod is hinged to a second movable plate. The upper and lower parts of the connecting plates are located above and below the rotating shaft, respectively.

[0010] Preferably, the system also includes a control device, which controls the film feeding mechanism, the material feeding mechanism, the vertical heat sealing mechanism, the first pneumatic gripper, the pressing conveyor belt, and the horizontal heat sealing mechanism.

[0011] The beneficial effects of this utility model are as follows: By symmetrically distributing two pressing conveyor belts on the left and right sides of the discharge pipe, the film can be effectively pulled downwards. During the pulling process, the film is less likely to slip, ensuring that the height of the hot-pressed packaging bags remains consistent and improving the quality stability of the product.

[0025] The working process of this utility model:

[0026] In the operation of this utility model of a vertical automatic continuous bag making and packaging equipment, the film fed by the film feeding mechanism 11 passes through the gap between the discharge pipe 13 and the limiting cylinder 14 to form a cylindrical shape. When the film passes through, both sides of the film pass through the film-passing seam 15. The vertical heat sealing mechanism 3 intermittently heat seals the two sides of the film together. The heat sealing interval of the vertical heat sealing mechanism 3 needs to ensure that the heat sealing parts of the two consecutive heat sealing parts are connected together. The pressing conveyor belt 2 is pressed tightly against the film under the action of the first pneumatic clamping claw 20. The pressing conveyor belt 2 intermittently pulls the film downward. When the pressing conveyor belt 2 pulls the film downward, the vertical heat sealing mechanism 3 is in the open state. The horizontal heat sealing mechanism 4 intermittently heat seals the film. When the horizontal heat sealing mechanism 4 is in the open and non-moving state, the feeding mechanism 12 feeds the material.
