[0001] The invention relates to the technical field of stretch film packaging, and in particular to a stretch film packaging robot. Background Art

[0002] In modern industrial production, stretch film packaging is an important way to protect and organize products, and is widely used in various fields, such as food and beverage, can making, paper making and other industries.

[0015] Compared with the prior art, the advantages of the present invention are: 1. The present invention provides a plurality of support shells to press against the inner wall of the cardboard roller from the inside to support and position the cardboard roller, so that the cardboard roller will not shake or deviate at will during the winding process, thereby ensuring the stability and accuracy of the winding. The distance between the support shell and the support shaft is adjusted by the second electric column, so that cardboard rollers with different inner diameters can be adapted, thereby improving the applicability of the equipment. The rubber disc has certain elasticity and flexibility. When the support shell presses against the inner wall of the cardboard roller, the rubber disc is deformed and stretched outward, thereby increasing the contact area with the inner wall of the cardboard roller. At the same time, the air extraction component extracts the air between the rubber disc and the cardboard roller to form a negative pressure, thereby generating an adsorption effect, further enhancing the fixing effect on the cardboard roller, preventing the cardboard roller from sliding or rotating unsmoothly during the winding process, thereby improving the winding quality. The rubber disc has a relatively soft texture, and when in contact with the cardboard roller, it can avoid scratching or damaging the surface of the cardboard roller, thereby extending the service life of the cardboard roller.

[0016] 2. The present invention sets an outer baffle plate to press against the end of the cardboard roller, effectively limiting the cardboard roller in the axial direction, preventing the cardboard roller from axially moving on the support shaft, ensuring that the cardboard roller is always in the correct position, and further ensuring that the wrapping film is neatly and tightly rolled up. Combined with the support and fixation of the inner wall of the cardboard roller by the support shell, the cardboard roller is constrained from multiple directions, making the cardboard roller more stable during winding, reducing shaking and deviation, improving the stability of equipment operation, and avoiding the winding effect being affected by the shaking of the cardboard roller. For cardboard rollers of different lengths, the position of the outer baffle block can be adjusted by the electric telescopic rod, and the first electric column adjusts the angle of the outer baffle plate so that the outer baffle plate accurately presses against the end of the cardboard roller, thereby improving the adaptability of the equipment to cardboard rollers of different specifications.

[0017] 3. In the present invention, when the support shaft rotates to roll up the film, the pressure plate flattens the film to ensure that the film remains flat during the rolling process and avoids wrinkles or uneven overlap, which helps to improve the quality of the rolled film and make it tighter and smoother. The pressure rod can adjust its length according to the diameter of the film roll to ensure that the pressure plate always acts on the film with appropriate pressure, avoiding the problem of excessive or insufficient local force, and preventing the film from being damaged due to excessive local force during the rolling process, or being loosely rolled up due to insufficient force.

[0018] 4. The present invention provides continuous and stable friction between the electric roller and the inner wall of the cardboard roller by arranging silicone rubber bumps on the surface of the electric roller, thereby ensuring that the cardboard roller is pushed outward smoothly, avoiding the difficulty in pushing due to insufficient friction, or the cardboard roller pausing or getting stuck during the pushing process due to a sudden change in friction, and preventing the cardboard roller from slipping during the pushing process, thereby improving the efficiency of the entire packaging workflow. The silicone rubber has certain elasticity and softness, and will not cause scratches, wear and other damages to the inner wall of the cardboard roller due to excessive friction, which helps to ensure the integrity and surface quality of the cardboard roller.

[0019] 5. The present invention realizes continuous winding and automatic unloading of multiple winding assemblies by setting devices such as a rotating disk and a winding assembly, thereby improving production efficiency. The rotation of the rotating disk can accurately control the position of the winding assembly, ensuring that each group of winding assemblies can accurately reach the specified position during winding, unloading and other operations, ensuring the accuracy and stability of the operation, which is conducive to improving product quality and production consistency.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

A plurality of second electric columns 11 are fixedly installed on the support shell 10, and the plurality of second electric columns 11 correspond to the positions of the plurality of support shells 10 respectively, and the telescopic ends of the second electric columns 11 are fixedly connected to the support shell 10, and a plurality of rubber discs 20 are fixedly installed on the outer walls of the plurality of support shells 10, and the plurality of rubber discs 20 are evenly distributed on the outer walls of the support shell 10, and a plurality of exhaust components are arranged inside the support shell 10, and the plurality of exhaust components correspond to the positions of the plurality of rubber discs 20 respectively, and the exhaust components include an exhaust groove 17 opened in the support shell 10, and an exhaust rod 18 and an exhaust member 1901 are fixedly installed on the inner wall of the exhaust groove 17, and a gas pressure plug 1902 is fixedly installed on the telescopic end of the exhaust rod 18, and the gas pressure plug 1902 is located at The vacuum member 1901 is in the vacuum member 1901 and is slidably connected to the inner wall of the vacuum member 1901. The end of the vacuum member 1901 away from the vacuum rod 18 is fixedly connected to the corresponding rubber disk 20. Before the winding work, the cardboard roller is sleeved on the support shaft 22. By starting the second electric column 11, multiple support shells 10 are moved in the direction away from the support shaft 22 and against the inner wall of the cardboard roller. It can be adaptively adjusted according to cardboard rollers with different inner diameters to ensure that the cardboard roller will not shake or shift during the winding process, thereby ensuring the stability and quality of the winding of the wrapping film. When the support shell 10 is against the inner wall of the cardboard roller, the rubber disk 20 is deformed and expanded outward, increasing the contact area with the inner wall of the cardboard roller and The friction force further prevents the cardboard roller from slipping during the rotation process, ensuring the smooth progress of the winding work, and then the air extraction rod 18 and the air pressure plug 1902 are used to extract the air between the rubber disk 20 and the cardboard roller, so that a certain negative pressure is formed between the rubber disk 20 and the cardboard roller, producing an adsorption effect, further enhancing the fixing effect on the cardboard roller, even in high-speed rotation or more complex working environments, it can effectively prevent the cardboard roller from falling off, and improve the safety and reliability of equipment operation. The rubber disk 20 has a certain elasticity and will not cause hard damage to the inner wall of the cardboard roller when fixing it. Compared with some rigid fixing methods, it can better protect the integrity of the cardboard roller and extend its service life.

[0024] The end of the support shaft 22 away from the first motor 23 is fixedly connected to an outer block through an electric telescopic rod, and the outer wall of the outer block is rotatably connected to multiple outer baffles 12, and the multiple outer baffles 12 are distributed in a ring array on the outer wall of the outer block, and multiple first electric columns 9 are fixedly installed inside the outer block, and the multiple first electric columns 9 correspond to the positions of the multiple outer baffles 12 respectively, and the telescopic end of the first electric column 9 is rotatably connected to the outer baffle 12, and the cardboard roller is installed on the support shaft 22, and then the position of the outer block and the outer baffle 12 is adjusted by the electric telescopic rod and the first electric column 9. The multiple outer baffles 12 are radially expanded to form an umbrella-shaped support structure, and abut against the end of the cardboard roller, which can effectively limit the cardboard roller in the axial direction to prevent it from axially moving on the support shaft 22, ensuring that the cardboard roller always remains in the correct position during the winding process, ensuring that the wound film is neat and tight, and improving the packaging quality. Combined with the support and fixation of the inner wall of the cardboard roller by the support shell 10, the outer The limiting of the end by the baffle 12 further enhances the fixing effect of the cardboard roller on the support shaft 22, constrains the cardboard roller from multiple directions, makes the cardboard roller more stable during winding, reduces shaking and deviation, and improves the stability of the equipment operation. The outer baffle is connected to the support shaft 22 through an electric telescopic rod, and the outer baffle 12 is rotated and adjusted through the first electric column 9, so that the equipment can adapt to cardboard rollers of different lengths. For cardboard rollers of different specifications, it is only necessary to adjust the position of the outer baffle through the electric telescopic rod, and then adjust the angle of the outer baffle 12 through the first electric column 9, so that the outer baffle 12 can accurately resist the end of the cardboard roller, thereby improving the versatility and applicability of the equipment. The outer baffle 12 can usually be made of a material with a certain degree of elasticity or a buffer pad can be set at the position in contact with the cardboard roller. When it resists the end of the cardboard roller, it can play a buffering role to avoid hard damage to the end of the cardboard roller, and prevent the winding quality of the wrapping film from being affected by damage to the end.

[0025] A connecting shaft 3 is fixedly installed at the center of the rotating disk 2, an outer disk 4 is fixedly installed on the outer wall of the connecting shaft 3, a plurality of fixed plates 5 are fixedly installed on the outer wall of the outer disk 4, and a plurality of pressure plates 7 are rotatably connected to the outer wall of the connecting shaft 3 through a rotating member 8, and the plurality of pressure plates 7 correspond to the positions of the plurality of fixed plates 5 respectively, and a plurality of pressure rods 6 are fixedly installed on the side wall of the fixed plate 5, and one end of the pressure rod 6 away from the fixed plate 5 is rotatably connected to the corresponding pressure plate 7. When the first motor 23 drives the support shaft 22 to rotate to rewind the film, the pressure plate 7 can flatten the film, which can avoid wrinkles and uneven overlap of the film during the rewinding process. , making the rolled film smoother and tighter, which helps to improve the unfolding effect of the film in subsequent use, and is also conducive to ensuring the beauty and firmness of the packaging. The pressure rod 6 will shrink according to the degree of winding, so as to ensure that the pressure plate 7 always packs the film with the best pressure. In the early stage of winding, the diameter of the film roll is small, and the pressure rod 6 is in a relatively stretched state. As the winding proceeds, the diameter of the film roll gradually increases, and the pressure rod 6 will shrink accordingly, ensuring that the pressure applied by the pressure plate 7 on the film is uniform and appropriate. The uniform pressure helps to prevent the film from being damaged due to excessive force locally, or being loosely rolled due to insufficient force.

[0026] The side walls of the ends of the multiple support shells 10 away from the first motor 23 are all provided with a pushing assembly, and the pushing assembly includes a sliding groove 13 opened on the outer wall of the support shell 10, and the inner wall of the sliding groove 13 is rotatably connected to a connecting member 15 through a rotating shaft 14, and the end of the connecting member 15 away from the rotating shaft 14 is rotatably connected to an electric roller 16. After the rewinding is completed, the air pumping rod 18 pulls the air pressure plug 1902, so that air enters between the rubber disk 20 and the cardboard roller from the air pumping member 1901, eliminates the negative pressure, and makes the space between the rubber disk 20 and the cardboard roller The adsorption force disappears, reducing the difficulty of disassembling the cardboard roller, making it convenient to remove the cardboard roller from the support shaft 22, and improving work efficiency. The rotation of the rotary disk 2 allows multiple groups of winding components to perform winding work in sequence. When the wound cardboard roller follows the rotary disk 2 to rotate to a position corresponding to the conveying device 21, the outer baffle plate 12 approaches the outer block under the action of the first electric column 9, releasing the limit on the cardboard roller. Subsequently, the rotating shaft 14 starts to drive the connecting member 15 to lift upward, so that the electric roller 16 contacts the inner wall of the cardboard roller, and the electric The movable roller 16 rotates to push the rolled cardboard roll outward and finally drops it onto the conveyor belt of the conveying device 21. The conveying device 21 conveys the rolled cardboard roll to the box body, realizing automatic unloading, saving manpower and time, and improving work efficiency. The rotating disk 2 rotates to make multiple groups of winding components perform winding work in turn. After winding is completed, the material can be unloaded automatically and in time, ensuring the continuity of the entire packaging work, reducing the idle time of the equipment, and improving production efficiency. Low-viscosity silicone rubber bumps are arranged on the outer side of the electric roller 16. The low-viscosity silicone rubber bumps have a moderate surface friction coefficient and elasticity. When pushing the cardboard roll, it can provide sufficient friction to push the cardboard roll without damaging the surface of the cardboard roll due to excessive friction, thereby protecting the integrity and quality of the product. The silicone rubber can firmly adhere to the surface of the electric roller 16, ensuring that the friction point is stable during the pushing process, providing continuous and stable friction, so that the cardboard roll is smoothly pushed to the conveying device 21, avoiding damage to the cardboard roll or loosening of the wrapped film due to instability during the pushing process.

[0027] When the present invention is in use, the cardboard roller is first installed on the support shaft 22, and the second motor 24 is used to drive the rotating disk 2 to rotate. The support shaft 22 is provided with a first electric column 9 and an outer baffle 12. After the cardboard roller is sleeved on the outer wall of the support shaft 22, the first electric column 9 is started to push the outer baffle 12 to lift up, and the outer baffle 12 has a limiting effect on the cardboard roller to prevent the cardboard roller from shaking and affecting the later winding work. An annular rubber disk 20 is arranged on the outside of the support shell 10. When the second electric column 11 is not started, a plurality of support shells 10 are wrapped around the support shaft 22 in a cylindrical shape. After the second electric column 11 is started, the plurality of support shells 10 are dispersed to the surroundings, and the extension and contraction of the second electric column 11 are flexibly adjusted according to the inner diameter of the cardboard roller. The rubber disc 20 moves synchronously with the supporting shell 10 to increase its extension length. When the rubber disc 20 contacts the inner wall of the cardboard roller, it will be squeezed and extended outward to discharge the internal air. Then the vacuum rod 18 installed inside the supporting shell 10 starts to pump air. The vacuum rod 18 pulls the air pressure plug 1902 to slide downward along the inner wall of the vacuum member 1901 to pump air, and the air inside the rubber disc 20 is pumped out, thereby forming a small negative pressure environment, so that the rubber disc 20 and the inner wall of the cardboard roller are more firmly adsorbed. Compared with the existing clamping type manipulator, this method will not cause damage to the inner wall of the cardboard roller, and can also prevent the cardboard roller from sliding during the winding process, thereby preventing problems such as wrinkles during winding.

[0028] When the cardboard roller is fixed, the first motor 23 starts and drives the support shaft 22 to rotate, and the cardboard roller begins to roll up the film. The pressure plate 7 flattens the rolled film when the film is rolled up to reduce film wrinkles. The pressure rod 6 will be telescopically adjusted according to the degree of rolling up, so as to ensure that the pressure plate 7 always flattens the film with the optimal pressure. When the cardboard roller on the far right is packed, the rotating disk 2 rotates counterclockwise to make the support shaft 22 at the lower end rotate upward, and then the rolling work is carried out. When the rolled cardboard roller moves to the far left corresponding to the position of the conveying device 21, the exhaust rod 18 pulls down the air pressure plug 1902 to make it separate from the exhaust part 1901, so that the air in the exhaust groove 17 enters the rubber disk 20, and the negative pressure state of the rubber disk 20 is released, so that it loses suction. After the negative pressure state is released, the exhaust rod 18 slowly rebounds, and the rubber disk 20 supports the cardboard roller. Then the first electric column 9 drives the outer baffle 12 to retract, and then starts the support shell 10. The rotating shaft 14 drives the connecting member 15 to be lifted upward, and the connecting member 15 drives the electric roller 16 to move upward at the same time, so that the electric roller 16 contacts the inner wall of the cardboard roller. The outer side of the electric roller 16 is provided with low-viscosity silicone rubber bumps. The silicone rubber has excellent adhesion ability and can be firmly attached to the surface of the electric roller 16 without falling off, ensuring that the friction point of the electric roller 16 remains stable during the process of pushing the cardboard roller, and can provide continuous friction. The low-viscosity silicone rubber has a certain elasticity and softness after curing, and its surface friction coefficient is moderate, so that when the electric roller 16 contacts the cardboard roller, it can generate enough friction to push the cardboard roller, and will not damage the surface of the cardboard roller or cause the cardboard roller to slip due to excessive friction, and at the same time reduce the damage to the inner wall of the cardboard roller. The electric roller 16 rotates to push the rolled cardboard roller outward, causing it to fall onto the conveying device 21, and finally transported to the box by the conveying device 21 for stacking.
