Description

Technical Field

[0001] The invention relates to the technical field of film cutting equipment, in particular to an automatic film cutting machine. Background Art

[0002] Pallet, also known as stacking board and plywood, comes from the Chinese national standard "Logistics Terminology". It refers to a horizontal platform device used for the collection, stacking, handling and transportation of goods and products as unit loads. As a kind of container equipment similar to containers, pallets are now widely used in production, transportation, warehousing and circulation, and are considered to be one of the two key innovations in the logistics industry in the 20th century. As an important loading, unloading, storage and transportation equipment in the process of logistics operations, pallets play a huge role in modern logistics when used in conjunction with forks, stackers, elevators and other equipment. The benefits they bring to the modern logistics industry are mainly reflected in: they can realize the unitization, standardization and standardization of item packaging, protect items, and facilitate logistics and business flows. There are many types of pallets in logistics, according to the material, purpose, table, fork entry method and structure.

[0003] After the pallet is wrapped with protective film, it is difficult to be transported by forklift, so the protective film on both sides of the pallet needs to be cut.

[0004] However, the traditional disassembly and assembly method of manually removing the packaging film to prepare for the fork not only requires high labor costs, but also has extremely low efficiency, and it is difficult to keep up with the pace of today's automated and modernized industry.

[0005] Therefore, it is necessary to provide an automatic film cutting machine to solve the above technical problems. Summary of the invention

[0006] The purpose of the present invention is to provide an automatic film cutting machine to solve the problem that the traditional disassembly and assembly method of manually removing the packaging film for picking up by a fork in the above-mentioned background technology not only requires high labor costs, but also has extremely low efficiency and is difficult to keep up with the pace of the current trend towards automation and modern industry.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an automatic film cutting machine comprises a frame, a power mechanism is arranged inside the frame, a cutting mechanism is arranged at the output end of the power mechanism, and the cutting mechanism can be driven to extend or retract by the power mechanism.

[0008] The power mechanism is a device such as a cylinder or an electric push rod that can output linear power;

[0009] The cutting mechanism comprises a tool holder, which is arranged at the output end of the cylinder and fixed to the output end of the power mechanism. A tool is fixedly arranged on the outer side of the tool holder, and the tool is arranged in a sawtooth shape.

[0010] During specific use, the power mechanism can drive the cutting mechanism to extend or retract, thereby cutting the protective film on the outside of the pallet. The knife is set to be serrated. Such a blade is sharper and has a guiding role when cutting. It is not easy to push the goods off due to blade bluntness.

[0011] As a further solution of the present invention, a protective shell is arranged on the outside of the frame, and the protective shell is fixed to the frame by screws.

[0012] During specific use, the protective shell is helpful for protecting the components inside the rack.

[0013] As a further solution of the present invention, a solenoid valve is provided at the connecting end of the cylinder, and a first rubber air tube and a second rubber air tube are provided at the output end of the solenoid valve. The first rubber air tube is provided at the rear end of the cylinder and is connected to the cylinder, and the second rubber air tube is provided at the front end of the cylinder and is connected to the cylinder. A positioning plate is provided at the output end of the cylinder, and the positioning plate and the cylinder are both fixed to the frame.

[0014] During specific use, the gas delivery inside the first rubber air tube and the second rubber air tube is controlled by the solenoid valve. When the gas is delivered to the rear end of the cylinder through the first rubber air tube, the output end of the cylinder can be driven to move forward, thereby driving the tool holder and the tool to move forward through the output end of the cylinder, which is beneficial to cutting the protective film through the tool. When the gas is delivered to the front end of the cylinder through the second rubber air tube, the output end of the cylinder can be driven to move backward, thereby driving the tool holder and the tool to be retracted, which is beneficial to the next cutting.

[0015] As a further solution of the present invention, the tool is fixed to the tool holder by means of screws.

[0016] During specific use, the tool holder is beneficial to the installation of the tool.

[0017] As a further solution of the present invention, a guide rod is provided on the side of the tool holder close to the cylinder, and the guide rod penetrates the positioning plate and is slidably connected to the positioning plate.

[0018] During specific use, by providing a guide rod, the guide rod passes through the positioning plate and is slidably connected to the positioning rod, which is conducive to the stable forward and backward movement of the tool by the output end of the cylinder.

[0019] As a further solution of the present invention, a accommodating chamber is provided at the bottom end of the frame, the tool holder and the tool are placed inside the accommodating chamber, the front end of the tool is provided with tool teeth, and the tool teeth are offset inward by 3° to 6°.

[0020] When used specifically, the best cutting effect is achieved when the blade teeth are offset inward by 3° to 6°. Such a blade is sharper and has a guiding effect when cutting, and is less likely to deflect the goods due to blade blunting.

[0021] As a further solution of the present invention, the tool includes a main cutting edge and two auxiliary cutting edges, and the two auxiliary cutting edges are arranged on both sides of the top of the main cutting edge.

[0022] During specific use, the tool is divided into a cutting structure of a main blade and two auxiliary blades. The two auxiliary blades are arranged on both sides of the top of the main blade. This tool adopts a multi-point contact cutting method, the cutting force is more uniform, the tooth tip is in point contact, the unit area is smaller during cutting, the force is unchanged, the pressure is increased, and cutting is easier.

[0023] As a further solution of the present invention, a conveyor is provided on one side of the frame, a pallet is provided on the conveyor, a penetrating square groove is provided on the outer side of the pallet, and a protective film is wrapped around the outer side of the pallet.

[0024] During specific use, the tool is driven by the cylinder to move toward one side of the pallet, so that the tool is inserted into the square groove, which is beneficial to cutting the protective film, thereby facilitating the handling and transportation of the pallet in the later stage, and is more convenient in actual operation. The present invention adopts the preferred method of directly using the cylinder piston rod as the active axis, and uses the method of directly outputting energy in a straight line, which greatly reduces the energy loss and has a large output energy. In addition, the tool adopts a serrated and angled blade. The serrated shape has multiple points of contact, and the cutting force is more balanced. The point contact increases the pressure per unit area, making it easier to cut and will not deflect the goods. Multiple points involved in cutting make the force on the goods more balanced. Compared with traditional manual cutting methods, it is more efficient, has a simple structure, and is easy to operate.

[0025] Working principle: The gas delivery inside the first rubber air tube and the second rubber air tube is controlled by the solenoid valve. When the gas is delivered to the rear end of the cylinder through the first rubber air tube, the output end of the cylinder can be driven to move forward, thereby driving the tool holder and the tool to move forward through the output end of the cylinder, which is beneficial to cutting the protective film through the tool. The gas delivered to the front end of the cylinder through the second rubber air tube can drive the output end of the cylinder to move backward, thereby driving the tool holder and the tool to be retracted, which is beneficial to the next cutting. The guide rod is provided, and the guide rod passes through the positioning plate and is slidably connected to the positioning rod, which is beneficial to the output end of the cylinder to stably drive the tool to move forward and backward, and the tool is driven to move toward one side of the tray through the cylinder. Inserting the tool into the square groove is conducive to cutting the protective film, which is beneficial to the later handling and transportation of the pallet, and is more convenient in actual operation. The present invention adopts the method of directly using the cylinder piston rod as the active axis, and uses the method of directly outputting energy in a straight line, which greatly reduces the energy loss and has a large output energy. In addition, the tool adopts a serrated and angled blade. The serrated shape has multiple points of contact, and the cutting force is more balanced. The point contact increases the pressure per unit area, making it easier to cut and will not deflect the goods. Multiple points involved in cutting make the force on the goods more balanced. Compared with traditional manual cutting methods, it is more efficient, has a simple structure, and is easy to operate.

[0026] The automatic film cutting machine described in the present invention is a device that can output linear power through a cylinder or an electric push rod. The output end of the power mechanism drives the tool holder and the tool to move forward, and the output end of the power mechanism drives the tool to move toward one side of the pallet to insert the tool into the square groove, which is beneficial to cutting the protective film, thereby facilitating the later handling and transportation of the pallet, and is more convenient in actual operation. The present invention preferably adopts the method of directly using the cylinder piston rod as the active shaft, and uses the method of directly outputting energy in a linear manner, which greatly reduces the energy loss.
