Description

Technical Field

[0001] This utility model relates to the field of bubble bag production technology, specifically to a bubble film feeding device for bubble bag production. Background Technology

[0002] In the production of bubble wrap, bubble wrap feeding is a crucial step. The stability and quality of bubble wrap feeding directly affect the efficiency and quality of subsequent bubble wrap production. An efficient and stable bubble wrap feeding device can ensure the smooth transfer of bubble wrap during the feeding process, providing a strong guarantee for the smooth operation of the entire production process.

[0003] However, in traditional feeding devices, as the feeding roller feeds the material, its circumference continuously decreases, while the position of the pressing roller is often fixed or cannot be synchronized with the feeding roller's feeding process. This results in the bubble wrap gradually loosening and wrinkling in the later stages of feeding due to insufficient clamping force. These wrinkles not only affect the appearance quality of the bubble wrap but may also cause a series of problems in subsequent processing, such as causing bubble bag size deviations and uneven bubble distribution, which seriously reduces production efficiency and product quality. Utility Model Content

[0004] This application provides a bubble wrap feeding device for bubble bag production, and the technical solution provided by this application is as follows:

[0005] A bubble wrap feeding device for bubble bag production includes a support frame with a feeding roller mounted on it, a pressure roller, an elastic component, a pushing component, and a transmission component. The pressure roller is located on the inner side of the upper part of the support frame and is used to press the bubble wrap material discharged from the feeding roller. The elastic component is located on the inner wall of the upper part of the support frame and connected to the pressure roller, and is used to provide elastic pressure to the pressure roller. The pushing component is located on the side wall of the support frame. The transmission component is connected to the roller shaft end of the feeding roller. When the feeding roller is driven to rotate and feed the material, the transmission component is driven by the roller shaft end of the feeding roller and drives the pushing component to move horizontally. An inclined plate is fixed on the elastic component. The pushing component abuts against the inclined plate on the elastic component, thereby compressing the elastic component and causing the pressure roller to descend synchronously with the rotation of the feeding roller.

[0006] Furthermore, the elastic component includes a sleeve, a slide bar, a fixing block, and a spring. The sleeve is fixed to the inner walls on both sides of the bracket. The slide bar can be slidably inserted into the sleeve. The fixing block is fixed to the top of the slide bar and is rotatably connected to the roller shaft of the pressure roller. The spring is connected between the sleeve and the fixing block and is sleeved on the outer wall of the slide bar.

[0007] Furthermore, the pushing component includes a push rod and a push block. The push rod is mounted on the top of the bracket and is slidably connected to the bracket. The push block is fixed to the end of the push rod and abuts against the inclined plate.

[0008] Furthermore, the inclined plate is fixedly connected to the elastic component, and the tilt angle of the inclined plate is adjustable to adjust the compression stroke of the pushing component on the elastic component.

[0009] Furthermore, the transmission assembly includes a gear one connected to the end of the feed roller shaft, a gear two meshing with the gear one, a worm gear connected to the shaft of the gear two, a worm wheel meshing with the worm gear, a screw fixed on the worm wheel, and a threaded block threaded onto the screw, the threaded block being fixedly connected to the push assembly.

[0010] Furthermore, the diameter of gear one is smaller than that of gear two, and the ratio of the number of teeth of gear one to gear two is set according to the range of variation of the diameter of the feeding roller.

[0011] Furthermore, the threaded block is fixed with a T-shaped track rod one along the outer wall of the bracket and slides horizontally along the T-shaped track rod one, while the inclined plate is fixed with a T-shaped track rod two along the inner wall of the bracket and slides vertically along the T-shaped track rod two.

[0012] Furthermore, the outer surface of the pressure roller is provided with an anti-slip layer, which is made of rubber material.

[0013] Furthermore, the inclined plate has an inclination angle of 30° to 60°, and the surface of the inclined plate is provided with a wear-resistant coating.

[0014] Furthermore, it also includes a controller and sensors. The sensors are used to detect the tension of the bubble film, and the controller is electrically connected to the motor of the feeding roller to adjust the feeding speed according to the sensor signal.

[0015] Compared with the prior art, the beneficial effects of this application are:

[0016] 1. Through the coordinated design of the transmission component, the pushing component and the elastic component, the device ensures that as the feeding roller continuously feeds material and the diameter gradually decreases, the pressing roller can descend synchronously with the rotation of the feeding roller, always maintaining a suitable pressing force on the bubble wrap material. This ensures that the bubble wrap maintains a suitable tension during the feeding process, effectively avoiding loosening and wrinkling during feeding, greatly improving the stability of bubble wrap feeding, and ensuring the smooth progress of the production process.

[0017] 2. The device adopts a multi-stage transmission structure, that is, power transmission is achieved through the meshing of gear one and gear two, the cooperation of worm and worm wheel, and the threaded transmission of screw and threaded block. The diameter of gear one is much smaller than that of gear two. By utilizing this meshing relationship of large and small gears, the transmission ratio adjustment for speed increase or deceleration can be realized, which can more flexibly adapt to different feeding speed requirements.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] According to an embodiment of this utility model, this application discloses a bubble wrap feeding device for bubble bag production, referring to... Figure 1 and Figure 2 It includes a support 1, a feeding roller 2 placed on the inner wall of the support 1, a pressing roller 3, an elastic component 4, a pushing component 5, and a transmission component 6.

[0025] Reference Figure 1 and Figure 3A pressure roller 3 is located on the inner side of the upper part of the support 1. The outer surface of the pressure roller 3 is provided with an anti-slip layer made of rubber material. The pressure roller 3 is used to compress the bubble film material released by the feed roller 2. The elastic component 4 includes a sleeve 41 fixed to the inner walls of both sides of the support 1. A slide rod 42 is slidably inserted into the upper end of the sleeve 41, and a fixing block 43 is fixed at the top of the slide rod 42. The fixing block 43 is rotatably connected to the roller shaft of the pressure roller 3. A spring 44 is connected between the sleeve 41 and the fixing block 43, and the spring 44 is sleeved on the outer wall of the slide rod 42. The spring 44 provides elastic support force. An inclined plate 7 is fixed on the elastic component 4, and the inclination angle of the inclined plate 7 is adjustable. Preferably, the inclination angle is 30° to 60°, and the surface of the inclined plate is provided with a wear-resistant coating. This is used to adjust the compression stroke of the push component 5 on the elastic component 4. When the push component 5 pushes the inclined plate 7, the slide rod 42 slides in the sleeve 41, compresses the spring 44, and drives the pressure roller 3 to descend.

[0026] The pushing component 5 includes a push rod 51 that slides against the side wall of the bracket 1, and a push block 52 is fixed at the end of the push rod 51. The push block 52 abuts against the inclined plate 7. The motor drives the feeding roller 2 to make the transmission component 6 move, which drives the push rod 51 to slide along the side wall of the bracket 1. The push rod 51 drives the push block 52 at the end to move synchronously, and the push block 52 drives the inclined plate 7 to move horizontally.

[0027] Reference Figure 1 and Figure 3 The transmission assembly 6 is connected to the roller shaft end of the feeding roller 2. The transmission assembly 6 includes a first gear 61, a second gear 62, a worm gear 64, a worm 63, a screw 65, and a threaded block 66. The first gear 61 is connected to the roller shaft end of the feeding roller 2. The first gear 61 meshes with the second gear 62. The second gear 62 is connected to the axle of the worm gear 63. The worm gear 64 meshes with the worm gear 63. The screw 65 is fixed to the worm gear 64. The threaded block 66 is threaded onto the screw 65. The threaded block 66 is fixed to the pushing assembly 5.

[0028] Reference Figure 1 and Figure 3The rotation of the feeding roller 2 drives gear 61, which in turn drives gear 62, which in turn drives worm 63, worm 63, worm wheel 64, and worm wheel 64. Worm wheel 64 drives screw 65, which in turn drives threaded block 66 to move. Threaded block 66 then drives push rod 51, thus transmitting power. Furthermore, threaded block 66 is fixed to a T-shaped track rod 8 along the outer wall of bracket 1, allowing it to slide horizontally. Additionally, inclined plate 7 is fixed to a T-shaped track rod 9 along the inner wall of bracket 1, allowing it to slide vertically. Furthermore, inclined plate 7 is connected to fixed block 43; T-shaped track rod 8 restricts threaded block 66 to slide only horizontally, and T-shaped track rod 9 restricts inclined plate 7 to slide only vertically, ensuring that when push block 52 pushes inclined plate 7, inclined plate 7 can stably drive fixed block 43 and pressure roller 3 to move. When the feeding roller 2 is driven by the motor to rotate and feed the material, the roller shaft end of the feeding roller 2 drives the transmission component 6 connected to the end of the shaft to rotate, and the transmission component 6 drives the pushing component 5 to move horizontally. The elastic component 4 is fixed with an inclined plate 7. The pushing component 5 abuts against the inclined plate 7 fixed on the elastic component 4, thereby compressing the elastic component 4, so that the pressing roller 3 descends synchronously with the rotation of the feeding roller 2 to accommodate the decrease in circumference of the feeding roller 2 during feeding, and to ensure the tightness of the film material. Furthermore, it also includes a controller and a sensor. The sensor is used to detect the tension of the bubble film, and the controller is electrically connected to the motor of the feeding roller 2 to adjust the feeding speed according to the sensor signal.

[0029] The implementation process of a bubble wrap feeding device for bubble bag production according to an embodiment of this application is as follows:

[0030] During operation, the bubble wrap material is wrapped around the outside of the feeding roller. During feeding, it is transmitted through the drive rollers on the production line and pressed by the clamping rollers. It is worth noting that the overall intermediate transmission structure and cutting structure of the production line are existing technologies and will not be elaborated upon here. When the feeding roller starts to rotate and feed material driven by the motor, the roller shaft end drives the transmission component connected to the shaft end. Gear 1, connected to the roller shaft end, begins to rotate. Gear 1 drives gear 2 to rotate, and gear 2's shaft drives the worm gear connected to it to rotate. The worm gear meshes with the worm wheel, and the rotation of the worm wheel drives the screw fixed to it to rotate. A threaded block threaded onto the screw slides horizontally along a T-shaped track rod fixed to the outer wall of the bracket, thereby driving the push rod fixed thereto along the bracket. As the sidewall slides, the push block at the end of the push rod also moves horizontally in sync. During the horizontal movement of the pushing component, the push block engages with the inclined plate fixed on the elastic component. As the push block continues to move, it generates an upward thrust on the inclined plate. Since the inclined plate is connected to the fixed block and slides vertically along the T-shaped track rod fixed to the inner wall of the bracket, the slide bar of the elastic component slides downward within the sleeve, the spring is compressed, and the pressure roller descends synchronously with the material feeding roller as it rotates. As the material feeding roller continuously feeds, the diameter of the material feeding roller gradually decreases. The transmission component drives the pushing component to move horizontally continuously. Through its cooperation with the inclined plate, it continuously compresses the elastic component, and the pressure roller continues to descend, always maintaining a suitable pressure on the bubble wrap material. This ensures that the bubble wrap maintains a suitable tension during the feeding process and provides stable feeding.

[0031] It is worth noting that the diameter of gear one is much smaller than that of gear two, so that gear one, which is connected to the feeding roller, can drive gear two to rotate once only after rotating multiple times. Gear two can then drive the transmission through a worm and worm wheel, and in turn, use a screw to provide horizontal propulsion force to the threaded block. In addition, the slope of the contact surface between the inclined plate and the push block is small. In summary, this ensures that the pressing roller can descend in a matching manner when the feeding roller rotates to feed the material, thereby maintaining the bubble film material in an optimal compressed state and avoiding loosening and wrinkling during feeding. Furthermore, the motor used for driving is a stepper motor that can rotate in both directions, thereby driving the pressing roller to perform a reset operation.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
