Description

Technical Field

[0001] This utility model relates to the field of packaging machines, and in particular to an energy-saving and environmentally friendly automatic packaging machine. Background Technology

[0002] Packaging machines are mechanical devices used to seal products according to predetermined packaging requirements. They are widely used in many industries such as food, pharmaceuticals, chemicals, and daily chemicals. In the current packaging process, complex manual operations or the coordinated work of multiple independent mechanical devices are required to complete a series of packaging steps. For example, in the step of filling materials into packaging bags, traditional packaging machines often require manual placement of the bags in a fixed position and manual opening of the bag opening before starting the filling equipment to fill the material. This operation method is not only inefficient, but manual operation also makes it difficult to ensure that the opening degree and position of each packaging bag are completely consistent, easily leading to inaccurate material filling, leakage, or damage to the packaging bags, affecting packaging quality and production efficiency.

[0003] In addition, traditional packaging machines are partially driven by pneumatic or hydraulic systems. Pneumatic drives require equipment such as air compressors, which not only consumes more energy but also generates more noise. Hydraulic drives, on the other hand, pose a risk of hydraulic oil leakage. Once a leak occurs, it will not only pollute the environment but also affect the normal operation of the equipment and increase maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide an energy-saving and environmentally friendly automatic packaging machine that solves the problems of low efficiency and unstable packaging quality caused by the reliance on manual operation in traditional packaging machines, as well as the high energy consumption and environmental pollution caused by traditional drive methods.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An energy-saving and environmentally friendly automatic packaging machine includes a support frame, a vertical plate fixedly connected to the top of the support frame, a lifting motor fixedly installed on one side of the vertical plate, a hopper for holding materials to be packaged fixedly connected to the output end of the lifting motor, an installation base provided below the support frame, pads symmetrically provided on the top of the installation base, clamping blocks for holding packaging bags symmetrically rotatably connected to the top of the installation base, the clamping blocks can be rotated to fit with the corresponding pads, an electric push rod symmetrically rotatably connected to the top of the installation base, the output end of the electric push rod is rotatably connected to the corresponding clamping block, the clamping block is driven to rotate by the extension and retraction movement of the electric push rod, realizing the fitting or separation action of the clamping block and the pad, and an opening assembly provided at the bottom of the support frame for automatically opening the bag mouth of the packaging bag.

[0006] Preferably, the opening assembly includes a push rod motor, a connecting arm, and a suction cup. Push rod motors are symmetrically fixedly installed at the bottom of the bracket. The output ends of the two push rod motors are fixedly connected to the connecting arms. A suction cup is installed at the end of the connecting arm away from the output end of the push rod motor. The push rod motor provides power, the connecting arm transmits power and changes the direction of movement, and the suction cup is used to adsorb the opening of the packaging bag. Through their coordinated work, the opening of the packaging bag can be opened quickly and accurately.

[0007] Preferably, a material gate is symmetrically and rotatably connected to the outer side of the bottom of the hopper. The two material gates can fit together to close the discharge port of the hopper. An opening and closing motor is installed on one side of the hopper. A connecting plate is symmetrically and rotatably connected to the output end of the opening and closing motor. The bottom end of the connecting plate is rotatably connected to the corresponding material gate. The opening and closing mechanism composed of the material gate, the opening and closing motor and the connecting plate is used to control the opening and closing of the discharge port of the hopper.

[0008] Preferably, the mounting base is rotatably connected to an electric cylinder and a rotating arm. The output end of the electric cylinder is rotatably connected to the rotating arm, and the bottom end of the rotating arm is fixedly connected to a pallet for lifting the packaging bag. During material filling, the pallet can support the packaging bag, prevent the packaging bag from falling and deforming due to the weight of the material, and ensure the stability of the packaging bag's shape.

[0009] Preferably, the surface of the clamping block that contacts the packaging bag is provided with an anti-slip pad. Since the surface of the packaging bag is usually smooth, without anti-slip measures, the clamping block may slip when clamping the packaging bag, resulting in the packaging bag not being securely fixed and affecting subsequent packaging processes.

[0010] Preferably, the pallet is designed with an L-shaped bend to increase the contact area between the pallet and the packaging bag, improve the stability of lifting, and at the same time, this shape can better adapt to the shape of the packaging bag.

[0011] Preferably, when the two material gates are fitted together to seal the hopper, their bottom ends have a sharp wedge-shaped structure. Since the opening of the packaging bag may have a certain irregular shape after opening, the sharp wedge-shaped structure can make it easier to insert into the bag opening, avoiding damage to the bag opening due to difficulty in insertion.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] This invention automates a series of operations, from bag clamping, bag opening, material filling to bag lifting. An electric push rod drives the clamping block and pad to automatically clamp the bag. The opening assembly uses a push rod motor and suction cup to automatically open the bag opening. A lifting motor drives the hopper to descend for automatic filling. An electric cylinder and rotating arm drive the pallet to automatically lift the bag. The entire process requires minimal manual intervention, shortening packaging time and improving packaging efficiency.

[0014] When the hopper is sealed by two material gates that fit together, the bottom end has a sharp wedge-shaped structure. This structure guides the material gates as they are inserted into the opened bag opening, preventing collisions or jamming between the gates and the bag opening. This not only ensures that the material is accurately poured into the packaging bag, but also avoids equipment failure and energy waste caused by collisions or jamming, thus improving the reliability and energy efficiency of the packaging.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 3 This embodiment provides an energy-saving and environmentally friendly automatic packaging machine, including a support frame 1. A vertical plate 2 is fixedly connected to the top of the support frame 1. A lifting motor 3 is fixedly installed on one side of the vertical plate 2. The output end of the lifting motor 3 is fixedly connected to a hopper 4 for holding the material to be packaged. A mounting base 5 is provided below the support frame 1. A pad 6 is symmetrically arranged on the top of the mounting base 5. A clamping block 7 for clamping the packaging bag is symmetrically rotatably connected to the top of the mounting base 5. The clamping block 7 can be rotated to fit with the corresponding pad 6. An electric push rod 8 is symmetrically rotatably connected to the top of the mounting base 5. The output end of the electric push rod 8 is rotatably connected to the corresponding clamping block 7. The extension and retraction movement of the electric push rod 8 drives the clamping block 7 to rotate, realizing the fitting or separation action of the clamping block 7 and the pad 6. An opening assembly 9 is provided at the bottom of the support frame 1. The opening assembly 9 is used to automatically open the bag mouth of the packaging bag.

[0021] During the packaging operation, the electric push rod 8 extends and retracts, and its output end drives the clamping block 7 to rotate, so that the clamping block 7 fits with the pad block 6, thereby clamping the two sides of the packaging bag placed between the pad blocks 6. The opening component 9 automatically opens the bag mouth of the packaging bag, and the lifting motor 3 drives the hopper 4 to descend, so that the bottom of the hopper 4 is inserted into the packaging bag with the opened bag mouth, realizing automatic filling of materials.

[0022] The opening assembly 9 includes a push rod motor 91, a connecting arm 92, and a suction cup 93. The push rod motor 91 is symmetrically fixedly installed at the bottom of the bracket 1. The output ends of the two push rod motors 91 are fixedly connected to the connecting arm 92. The end of the connecting arm 92 away from the output end of the push rod motor 91 is equipped with a suction cup 93.

[0023] When it is necessary to open the packaging bag, the two push rod motors 91 drive the corresponding connecting arms 92 to move, so that the two suction cups 93 respectively adhere to both sides of the packaging bag opening. Then the two push rod motors 91 drive the connecting arms 92 to move in the opposite direction, thereby pulling open the packaging bag opening.

[0024] The bottom outer side of the hopper 4 is symmetrically connected to the material gate 41. The two material gates 41 can fit together to close the discharge port of the hopper 4. An opening and closing motor 42 is installed on one side of the hopper 4. The output end of the opening and closing motor 42 is symmetrically connected to the connecting piece 43. The bottom end of the connecting piece 43 is rotatably connected to the corresponding material gate 41.

[0025] During material filling, the opening and closing motor 42 starts, and its output end drives the connecting piece 43 to move. The connecting piece 43 then drives the two material gates 41 to rotate and open to both sides, so that the material in the hopper 4 can flow out smoothly. After filling is completed, the opening and closing motor 42 rotates in the opposite direction, driving the connecting piece 43 to move in the opposite direction, thereby causing the two material gates 41 to fit together and re-close the outlet of the hopper 4.

[0026] An electric cylinder 51 and a rotating arm 52 are rotatably connected inside the mounting base 5. The output end of the electric cylinder 51 is rotatably connected to the rotating arm 52, and a tray 53 for lifting and supporting the packaging bag is fixedly connected to the bottom end of the rotating arm 52.

[0027] During the packaging process, when it is necessary to lift the packaging bag, the electric cylinder 51 extends and retracts, and its output end drives the rotating arm 52 to rotate. The rotating arm 52 then drives the pallet 53 to move closer to the packaging bag until the pallet 53 contacts the bottom of the packaging bag and stably lifts it. When the lifting operation is completed or when lifting is no longer necessary, the electric cylinder 51 moves in the opposite direction, driving the rotating arm 52 to rotate in the opposite direction, so that the pallet 53 moves away from the packaging bag.

[0028] The surface of the clamping block 7 that contacts the packaging bag is provided with an anti-slip pad. When the clamping block 7 clamps the packaging bag, the anti-slip pad increases the friction between the clamping block 7 and the packaging bag.

[0029] The pallet 53 is designed in an L-shape. When lifting the packaging bag, the bent part of the L-shaped pallet 53 can better fit the bottom and sides of the packaging bag.

[0030] When the two material gates 41 are fitted together to seal the hopper 4, their bottom ends form a sharp wedge-shaped structure. During the process of inserting the bottom end of the hopper 4 into the opened bag opening, the sharp wedge-shaped structure at the bottom end of the two material gates 41 can play a guiding role, allowing the material gates 41 to enter the bag opening more smoothly.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
