Description

Technical Field

[0001] The present invention relates to the technical field of packaging devices, in particular to a packaging device for automatic wrapping of packaging films. Background Art

[0002] In the field of processing and manufacturing, product packaging and packing plays a vital role in ensuring product quality and improving product appearance. Especially for products with higher quality requirements, perfect outer packaging is the key to preventing them from being damaged, rusted or broken during warehousing, transportation, storage, etc.

[0003] However, the product packaging method currently adopted by traditional manufacturing companies, especially refined outer packaging, mainly relies on manual operation, which has many disadvantages: manual packaging is difficult to meet the needs of large-scale operations. In the modern production environment, the scale of production continues to expand and the order volume increases. The speed of manual packaging is far behind the production rhythm, which seriously restricts the improvement of production efficiency. Since manual packaging is greatly affected by subjective factors such as personal skills and work status, there are obvious differences in the appearance quality of products packaged by different workers. This not only affects the overall aesthetics of the product, but may also cause customers to question the product quality.

[0004] On the one hand, manual packaging increases investment costs. On the other hand, the low efficiency of manual packaging leads to an extended production cycle, which indirectly increases the company's operating costs. The workpieces cannot be packaged conveniently, and the packaging efficiency needs to be improved. For the sticky wrapping tape, there is a lack of auxiliary structure to make it fit more closely with the workpiece. In view of this, we proposed an automatic wrapping and packaging device for packaging film. Summary of the Invention

[0020] Compared with the prior art, the present invention provides a packaging film automatic wrapping packaging device, which has the following beneficial effects:

[0021] 1. The automatic wrapping and packaging device of the packaging film is used to better package the workpiece. By setting a packaging component, the conveying motor on the first limit bracket is first started to rotate the conveying roller to transport the workpiece in one direction. When the workpiece passes the fixed base, the driving motor on the steel structure frame is started to make the rotating shaft drive the driving gear to rotate, and cooperate with the transmission of the rotating gear to make it rotate inside the supporting roller group, driving the round rod and the winding belt box to synchronously revolve around the center of the rotating gear, so that the winding belt body is wrapped around the outside of the workpiece. As the workpiece continues to move laterally, the packaging is completed. With the cooperation of the fixed block and the fixed rod, the auxiliary gear rotates synchronously, making the rotation of the rotating gear more stable, and with the support of the second limit bracket, the workpiece transportation is more stable.

[0022] 2. The automatic wrapping and packaging device for packaging film is equipped with auxiliary components to achieve better packaging effects. When the packaged workpiece is transported to the side of the first electric cylinder, the first electric cylinder is started in advance to make the second electric cylinder reach a preset height. The second electric cylinder is started to make the two sets of rectangular plates approach each other to a preset position. The preset position is set in advance according to the width of the current batch of workpieces, so that the workpiece will be squeezed by the side rollers on the side shaft, so that the wrapping belt body and the workpiece fit more closely, and at the same time, the workpiece can be transported backward along a path centered on the center of the conveyor roller, thereby achieving better packaging effects.

[0023] 3. The automatic wrapping and packaging device for packaging film is provided with a moving component to further improve the packaging effect. When the packaged workpiece is transported to the side of the vertical rod, the third electric cylinder is started in advance, so that the piston rod drives the U-shaped frame to move downward to a preset height. The preset height is set in advance according to the thickness of the workpieces of the current batch. The moving workpiece will be pressed by the top roller on the rotating rod, and the top roller rotates at the same time, so that the wrapping tape body and the workpiece fit more closely. At the same time, the movement of the U-shaped frame will drive the sliding rod to slide synchronously inside the sliding sleeve, so that the U-shaped frame moves up and down more stably, thereby further improving the packaging effect.

[0034] A packaging film automatic winding packaging device includes a frame 1, a first limiting bracket 2 is fixedly installed on the top of the frame 1, a conveying motor 3 is fixedly installed on the side wall of the first limiting bracket 2, a conveying roller 4 is provided at the output end of the conveying motor 3, the conveying roller 4 is rotatably installed on the first limiting bracket 2, and a workpiece 5 is provided on the conveying roller 4. In addition, two groups of the first limiting bracket 2, the conveying motor 3 and the conveying roller 4 are provided, and the rotation directions of the two groups of conveying rollers 4 are the same, so as to better perform unidirectional conveyance of the workpiece 5.

[0035] In one embodiment of the present invention, a packaging assembly 6 is provided on the top of the frame 1, and the packaging assembly 6 includes a fixed base 61. The fixed base 61 is fixedly installed on the top of the frame 1, and a steel structure frame 62 is fixedly installed on the outer wall of the fixed base 61. The steel structure frame 62 is located between the two groups of conveyor rollers 4. A drive motor 63 is fixedly installed on the outer wall of the steel structure frame 62. A rotating shaft 64 is fixedly installed on the output end of the drive motor 63. A driving gear 65 is fixedly installed on the outer wall of the rotating shaft 64. A supporting roller group 66 is rotatably installed inside the steel structure frame 62. The supporting roller group 66 is provided with multiple groups, and the arc-shaped outer wall of the rotating gear 67 is slidably fitted between the multiple groups of supporting roller groups 66. The rotating gear 67 engages the driving gear 65. In addition, the steel structure frame 62 and the rotating The rotating gear 67 is provided with a notch to facilitate the more rapid removal of the workpiece 5 through the notch. A round rod 68 is fixedly installed on the outer wall of the rotating gear 67, and a winding belt box 69 is clamped on the round rod 68. The winding belt box 69 is provided with a winding belt body 610. A fixed block 611 is fixedly installed on the outer wall of the steel structure frame 62, and a fixed rod 612 is rotatably installed inside the fixed block 611. An auxiliary gear 613 is fixedly installed on the fixed rod 612, and the auxiliary gear 613 engages with the rotating gear 67. A second limiting bracket 614 is fixedly installed on the top of the frame 1, and the top of the second limiting bracket 614 is in contact with the bottom end of the workpiece 5. In addition, the winding belt box 69 and the winding belt body 610 do not intersect with the second limiting bracket 614 to prevent motion interference.

[0036] When this embodiment is used, the entire packaging process starts with the conveying operation of the workpiece 5. The operator turns on the power of the equipment, so that the conveying motor 3 on the first limit bracket 2 is powered on and runs, and its output end drives the conveying roller 4 to rotate. Since the first limit bracket 2, the conveying motor 3 and the conveying roller 4 are provided with two groups, and the rotation directions of the two groups of conveying rollers 4 are the same, the workpiece 5 placed on the conveying roller 4 moves unidirectionally along the preset conveying direction under the action of friction, and moves smoothly toward the position of the packaging component 6. When the workpiece 5 moves to pass the fixed base 61, the drive motor 63 on the steel structure frame 62 is started, and its output end drives the rotating shaft 64 to rotate The rotating shaft 64 drives the driving gear 65 to rotate together, and the driving gear 65 and the rotating gear 67 mesh with each other. According to the gear transmission principle, the rotation of the driving gear 65 will transmit power to the rotating gear 67, so that the rotating gear 67 starts to rotate between the multiple sets of supporting rollers 66. The supporting rollers 66 support and guide the rotating gear 67 to ensure that the rotating gear 67 can move stably on the predetermined track. Since a round rod 68 is fixedly installed on the outer wall of the rotating gear 67, a winding belt box 69 is clamped on the round rod 68, and a winding belt body 610 is sleeved on the winding belt box 69. The end of the winding belt body 610 away from the winding belt box 69 has been manually placed on the outside of the workpiece 5. When the rotating gear 67 rotates, it will drive the round rod 68, the winding belt box 69 and the winding belt body 610 to revolve synchronously around the center of the rotating gear 67. The winding belt body 610 has a certain stickiness to the side of the workpiece 5. In this process, as the workpiece 5 continues to move laterally on the conveyor roller 4, the winding belt body 610 is gradually pulled out of the winding belt box 69 and wound around the outside of the workpiece 5. The structure of cutting the winding belt body 610 after the winding is completed is not shown in this application. Since it is the existing technology of the existing equipment, it will not be described here. At the same time, the auxiliary gear 613 fixedly installed on the fixed rod 612 is meshed with the rotating gear 67. The auxiliary gear 61 When the rotating gear 67 rotates, the support of the fixed block 611 and the fixed rod 612 can apply a stabilizing force to the rotating gear 67, thereby reducing the shaking and deviation of the rotating gear 67 during the rotation process, making the rotating gear 67 rotate more stably. The top end of the second limiting bracket 614 fixedly installed on the top of the frame 1 is in contact with the bottom end of the workpiece 5. During the conveying process of the workpiece 5, the second limiting bracket 614 can provide additional supporting force for the workpiece 5, preventing the workpiece 5 from tilting or falling during the conveying process, ensuring that the workpiece 5 moves stably along the conveyor roller 4, thereby ensuring that the winding belt body 610 can be evenly and tightly wound around the workpiece 5 to complete the initial packaging.

[0037] In one embodiment of the present invention, an auxiliary component 7 is provided on the outside of the workpiece 5, and the auxiliary component 7 includes a first electric cylinder 71, the top of the frame 1 is fixedly connected to the fixed end of the first electric cylinder 71, the piston end of the first electric cylinder 71 is fixedly connected to the fixed end of the second electric cylinder 72, and the piston end of the second electric cylinder 72 is fixedly installed with a rectangular plate 73. In addition, a side shaft 74 is fixedly installed inside the rectangular plate 73, and a side roller 75 is rotatably installed outside the side shaft 74, so that the winding belt body 610 and the workpiece 5 are more closely fitted. In addition, two groups of the first electric cylinder 71, the second electric cylinder 72 and the rectangular plate 73 are provided, and the two groups of the first electric cylinder 71, the second electric cylinder 72 and the rectangular plate 73 are all mirrored with the vertical center line of the conveyor roller 4, and are mirrored at both ends of the conveyor roller 4. There are multiple groups of side shafts 74 and side rollers 75 on the single group of rectangular plates 73, and the multiple groups of side shafts 74 and side rollers 75 are arranged in a linear array with equal spacing. The side rollers 75 can also reduce the friction of direct contact.

[0038] When this embodiment is used, when the packaged workpiece 5 is transported to the side of the first electric cylinder 71 under the drive of the conveyor roller 4, the first electric cylinder 71 is started in advance by the control system of the equipment according to the height parameters of the current batch of workpieces 5. The first electric cylinder 71 serves as a linear drive device, and its piston end pushes the second electric cylinder 72 fixedly connected to it to rise until the second electric cylinder 72 reaches a preset height. The setting of this preset height is based on the requirement that the side rollers 75 on the subsequent rectangular plate 73 can smoothly contact and apply pressure with the side of the workpiece 5, ensuring that the second electric cylinder 72 is in a suitable working position. After the second electric cylinder 72 reaches the preset height, the second electric cylinder 72 is started, and the piston end of the second electric cylinder 72 pushes the rectangular plate 73 fixedly installed at its end to move. Since the first electric cylinder 71, the second electric cylinder 72 and the rectangular plate 73 are provided in two groups, and are symmetrically arranged on the conveyor roller with the vertical center line of the conveyor roller 4 as the mirror axis. The two ends of the conveyor belt 4 are provided with two sets of rectangular plates 73, so the two sets of rectangular plates 73 will be close to each other. According to the width of the workpieces 5 of the current batch, the preset positions of the two sets of rectangular plates 73 close to each other are set in advance by the equipment control system. When the two sets of rectangular plates 73 move to the preset positions, the side rollers 75 on the side shafts 74 fixedly installed inside the rectangular plates 73 will contact the two side edges of the workpiece 5 and apply a certain pressure. The side rollers 75 will generate an inward squeezing force on the workpiece 5 under the action of pressure, so that the winding belt body 610 and the workpiece 5 fit more closely. At the same time, due to the rolling action of the side rollers 75, in the process of squeezing the workpiece 5, the workpiece 5 can be conveyed backward along the path centered on the conveyor roller 4 center, avoiding the workpiece 5 from deflecting during the conveying process, further improving the packaging effect, and multiple sets of side shafts 74 and side rollers 75 arranged in an equidistant linear array can evenly apply pressure to the workpiece 5 and reduce friction.

[0039] In one embodiment of the present invention, a moving component 8 is provided on the frame 1, and the moving component 8 includes a vertical rod 81, a vertical rod 81 is fixedly installed on the top of the frame 1, a fixed end of a third electric cylinder 82 is fixedly installed on the top of the vertical rod 81, the top of the piston end of the third electric cylinder 82 is fixedly installed on the piston rod 83, and the bottom of the piston rod 83 is fixedly connected to the top center of the U-shaped frame 84. In addition, a rotating rod 85 is installed inside the U-shaped frame 84, and a top roller 86 is rotatably installed on the outside of the rotating rod 85. The top roller 86 is located directly above the conveyor roller 4, so that the winding belt body 610 and the workpiece 5 fit more closely, and the top roller 86 can also reduce the friction of direct contact. In addition, a sliding rod 87 is fixedly installed on the top of the U-shaped frame 84, and a sliding sleeve 88 is fixedly installed inside the vertical rod 81. The sliding rod 87 is slidably installed inside the sliding sleeve 88, so that the U-shaped frame 84 moves up and down more stably.

[0040] When this embodiment is used, when the workpiece 5 moves on the conveyor roller 4 and is transported to the side of the vertical rod 81, the third electric cylinder 82 is started in advance by the equipment control system according to the thickness parameters of the current batch of workpieces 5, and the piston end of the third electric cylinder 82 drives the piston rod 83 fixedly connected thereto to move downward, and the piston rod 83 drives the U-shaped frame 84 to descend together. According to actual needs, the preset descending height of the third electric cylinder 82 is set in advance by the equipment control system. This preset height is to ensure that the top roller 86 on the rotating rod 85 inside the U-shaped frame 84 can properly contact and apply pressure to the top of the workpiece 5. When the U-shaped frame 84 descends to the preset height, the moving workpiece 5 will contact the top roller 86 on the rotating rod 85, and the top roller 86 will apply downward pressure on the top of the workpiece 5. The top roller 86 is located directly above the conveyor roller 4 and can rotate freely on the rotating rod 85. Therefore, when pressure is applied to the workpiece 5, the top roller 86 will rotate as the workpiece 5 moves. This dual effect of pressing and rotating can make the wrapping belt body 610 and the workpiece 5 fit more closely, further enhancing the firmness of the packaging. In addition, the sliding rod 87 fixedly installed on the top of the U-shaped frame 84 is slidably installed inside the sliding sleeve 88 fixedly installed inside the vertical rod 81. During the up and down movement of the U-shaped frame 84, the sliding rod 87 and the sliding sleeve 88 cooperate with each other to play a guiding and stabilizing role, limit the moving direction of the U-shaped frame 84, prevent it from shaking or offsetting during movement, and ensure that the U-shaped frame 84 can move up and down stably.

[0041] Among them, the electrical components appearing in this application document are all electrically connected to the controller and the 220V AC power supply, and the controller is a conventional known device that can control the conveying motor 3, the drive motor 63, the first electric cylinder 71, the second electric cylinder 72 and the third electric cylinder 82. The standard parts used in this application document can all be purchased on the market. The specific connection method of each part adopts the conventional means such as mature rivets and welding in the existing technology for connection, and the machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.
