Specific implementation

[0024] In order to make the utility model purposes, technical scheme and advantages more clearly, the following is connected with the drawings and example, and the utility model is further detailed.The specific embodiments described herein are used to explain the utility model, and are not used to limit the utility model.

[0025] The utility model provides a kind of waste foil weighing recovery device, its structure as shown in Figure 1 Figure 3 It includes support mechanism 1, weighing mechanism 2 and recovery mechanism 3.

[0026] The support mechanism 1 includes support 11 and rotating roller 12, the rotating roller 12 is rotatably connected to the top of support 11, and the waste foil roll is wound on the rotating roller 12.

[0027] The weighing mechanism 2 includes sensor 21, display 22 and controller, the sensor 21 and controller are arranged at the bottom of support 11, the display 22 is arranged on one side of support 11, the sensor 21 and controller are electrically connected, the controller and display 22 are electrically connected, the model of sensor 21 is VH110, the model of controller is GMT-X1, mainly applied to industrial weighing, and can be configured with amplifier, instrument and data acquisition device.

[0028] ​The recycling mechanism 3 comprises a recycling trolley 31, and the support 11 is provided with an opening 32 through which the recycling trolley 31 passes.

[0029] In use, the support 11 serves as the main supporting structure of the whole device and provides a stable mounting base for the rotating roller 12. The rotating roller 12 is rotatably connected to the top of the support 11, and the waste foil roll is wound on the rotating roller 12. This arrangement allows the waste foil roll to be conveniently placed on the device, and the rotating roller 12 can freely rotate, facilitating subsequent unwinding of the waste foil and other operations during recycling of the waste foil. The sensor 21 is arranged at the bottom of the support 11, and when the waste foil roll is placed on the rotating roller 12, the circuit inside the sensor 21 converts the physical quantity change caused by the weight into an electrical signal. This electrical signal accurately reflects the weight information of the waste foil roll, and then transmits the electrical signal to the display 22 through a wire. After receiving the electrical signal from the sensor 21, the display 22 analyzes and converts the signal through the internal processing circuit, and displays the weight value represented by the electrical signal in an intuitive form on the screen, so that the operator can clearly see the real-time weight of the waste foil roll. The recycling trolley 31 is used to collect the waste foil recycled from the waste foil roll. Before the recycling process starts, the recycling trolley 31 is pushed to the side of the support 11 and passes through the opening 32 arranged on the support 11, ensuring that the recycling trolley 31 is in a suitable position to receive the waste foil. When the waste foil roll is recycled, the removed waste foil directly falls into the recycling trolley 31 that has been positioned, realizing recycling and centralized collection of the waste foil, and facilitating further processing of the waste foil.

[0030] In the utility model, the sensor 21 in the weighing mechanism 2 can accurately perceive the weight change of the waste foil roll while recycling the waste foil, and can accurately convert the weight of the small or large waste foil roll into an electrical signal and clearly display it through the display 22, providing a reliable weight data basis for subsequent statistics, settlement and other work and improving the recycling efficiency.

[0031] For the convenience of unwinding the waste foil roll, please refer to Figure 1 In a preferred embodiment, the rotating roller 12 comprises a rotating rod 121, a supporting roller 122 coaxially arranged on the rotating rod 121, and two bearings 123 arranged at the two ends of the rotating rod 121, and the support 11 is provided with a supporting assembly 4 for supporting the bearings 123.

[0032] In use, first, the two bearings 123 are installed at both ends of the rotating rod 121. Then, the bearings 123 are supported by the support assemblies 4 on the support frame 11. The support assemblies 4 are designed to provide a stable mounting position for the bearings 123, ensuring that the rotating rod 121 can be placed horizontally and can rotate freely. The support roller 122 is coaxially arranged on the rotating rod 121, which is the part directly in contact with the waste foil roll. The surface of the support roller 122 can be relatively smooth to reduce the friction force on the waste foil roll, facilitating the winding and unwinding operations of the waste foil roll on the support roller 122. Because the bearings 123 at both ends of the rotating rod 121 are well supported by the support assemblies 4 of the support frame 11, the rotating rod 121 can rotate very smoothly under the action of the bearings 123. The rotation of the rotating rod 121 drives the coaxial support roller 122 to rotate, and the rotation of the support roller 122 enables the waste foil roll to stably unwind the waste foil, facilitating the recycling operation of the waste foil.

[0033] To support the bearings 123, please refer to Figure 2 In a preferred embodiment, the support assembly 4 includes a support plate 41 and a blocking plate 42, both of which are arranged on the support frame 11. The blocking plate 42 is located outside the support plate 41. The support plate 41 is provided with a support groove 43 that abuts the circumference of the bearing 123. The blocking plate 42 is provided with an avoidance groove 44 for the rotating rod 121 to pass through, and the blocking plate 42 abuts the outside of the bearing 123.

[0034] In use, when installing the rotating roller 12, first, the bearings 123 at both ends of the rotating rod 121 with the support roller 122 are respectively aligned with the corresponding support assemblies 4 on the support frame 11. The support groove 43 on the support plate 41 plays a precise positioning role for the bearings 123. When the bearings 123 are placed into the support groove 43, the shape and size of the support groove 43 are adapted to the circumference of the bearing 123, so that the bearing 123 can be accurately embedded therein. After the bearing 123 is embedded in the support groove 43 of the support plate 41, the wall surface of the support groove 43 will be in close abutment with the circumference of the bearing 123. Through this abutment, the support plate 41 provides an upward supporting force for the bearing 123 to bear the weight of the rotating rod 121, the support roller 122, and the waste foil roll, etc. The blocking plate 42 is located outside the support plate 41 and abuts the outside of the bearing 123. The avoidance groove 44 provided on the blocking plate 42 for the rotating rod 121 to pass through allows the rotating rod 121 to pass through smoothly, and the blocking plate 42 plays a limiting role on the outside of the bearing 123. It prevents the bearing 123 from being pulled out of the support groove 43 when subjected to external force, ensuring the fixed position of the bearing 123 in the horizontal direction and further enhancing the stability of the entire rotating roller 12 device during operation.

[0035] To limit the recycling cart 31, please refer to Figure 2In a preferred embodiment, the support 11 is provided with a limiting assembly 5 for limiting the movement of the recycling trolley 31.

[0036] In use, during the recycling of the waste foil, the recycling trolley 31 needs to be accurately stopped below the opening 32 on the side of the support 11 so as to be able to smoothly receive the waste foil recycled from the waste foil roll. The limiting assembly 5 can accurately limit the position of the recycling trolley 31, so that the recycling trolley 31 can be stopped at a fixed and accurate position each time, ensuring that the recycling trolley 31 is accurately docked with the waste foil outlet on the support 11. In this way, when the waste foil is taken off the waste foil roll and falls down, it can accurately and accurately fall into the recycling trolley 31, avoiding the waste foil from scattering outside the recycling trolley 31 due to inaccurate position of the recycling trolley 31, improving the accuracy and efficiency of the recycling of the waste foil.

[0037] In order to limit the recycling trolley 31, please refer to Figure 3 In a preferred embodiment, the limiting assembly 5 includes a limiting block 51 and two limiting clamping blocks 52, the limiting block 51 is arranged at the end of the recycling trolley 31, and the two limiting clamping blocks 52 are arranged on the support 11, and the two limiting clamping blocks 52 form a containing cavity 53 for containing the limiting block 51, and the support 11 is provided with a first driving assembly 6 for driving the limiting clamping block 52 to rotate.

[0038] In use, when the recycling trolley 31 is pushed to the designated position on the side of the support 11, the limiting block 51 arranged at the end of the recycling trolley 31 will gradually approach the containing cavity 53 between the two limiting clamping blocks 52 with the movement of the recycling trolley 31. Start the first driving assembly 6 on the support 11. Its function is to drive the limiting clamping block 52 to rotate. With the rotation of the limiting clamping block 52, the originally open containing cavity 53 gradually closes until the two limiting clamping blocks 52 tightly fit together, stably clamping the limiting block 51 in the containing cavity 53 formed by them. Thus, the limiting of the recycling trolley 31 in this direction is realized, ensuring that the recycling trolley 31 will not move laterally accidentally due to external force, and ensuring that the recycling trolley 31 can accurately dock with the waste foil outlet on the support 11 to smoothly receive the recycled waste foil.

[0039] In order to drive the limiting clamping block 52 to rotate, please refer to Figure 3 In a preferred embodiment, the first driving assembly 6 includes a torsion spring 61 arranged between the limiting clamping block 52 and the support 11, one end of the torsion spring 61 is connected to the limiting clamping block 52, the other end of the torsion spring 61 is connected to the support 11, and the two torsion springs 61 make the two limiting clamping blocks 52 tend to approach each other.

[0040] In use, when the recycling cart 31 is pushed to the right position, the limiting protrusion 51 at the end of the recycling cart 31 approaches the accommodating cavity 53 between the two limiting clamping blocks 52. The operator can manually pry the two limiting clamping blocks 52 apart to overcome the elastic force of the torsional spring 61, so that the accommodating cavity 53 is opened wide enough for the limiting protrusion 51 to enter smoothly. Once the limiting protrusion 51 enters the accommodating cavity 53, the operator releases the external force on the limiting clamping blocks 52. At this time, the elastic force of the torsional spring 61 comes into play. Since the torsional spring 61 always has a tendency to bring the two limiting clamping blocks 52 closer together, the two limiting clamping blocks 52 will quickly rotate and close in the middle under the driving force of the torsional spring 61, tightly clamping the limiting protrusion 51 in the accommodating cavity 53, thereby limiting the recycling cart 31 and preventing it from moving horizontally.

[0041] To reduce the possibility of damage to the limiting protrusion 51 and the limiting clamping block 52, please refer to Figure 3 In a preferred embodiment, the limiting protrusion 51 and the surfaces of the two limiting clamping blocks 52 are provided with a wear-resistant layer.

[0042] In use, during the use of the waste foil recycling device, the limiting protrusion 51 and the limiting clamping block 52 will frequently come into contact and friction with each other. Each time the recycling cart 31 is positioned and removed, the limiting clamping block 52 needs to clamp and release the limiting protrusion 51, which causes the contact surfaces to rub against each other continuously. The presence of the wear-resistant layer can effectively reduce the wear of the limiting protrusion 51 and the limiting clamping block 52 caused by friction. Compared to the case without a wear-resistant layer, the component with a wear-resistant layer can withstand more friction operations, thereby greatly extending the service life of the limiting protrusion 51 and the limiting clamping block 52, reducing the frequency of component replacement due to wear, and reducing the maintenance cost of the equipment.

[0043] To increase the accommodating volume of the recycling cart 31, please refer to Figure 1 In a preferred embodiment, the recycling cart 31 is provided with a compression assembly 7 for compressing waste foil.

[0044] In use, during the recycling of waste foil, the waste foil is usually collected in a loose state into the recycling cart 31. As the recycling progresses, the space in the recycling cart 31 will gradually be occupied. The compression assembly 7 can compress the collected waste foil, reducing the volume of the waste foil. In this way, more waste foil can be loaded into the same recycling cart 31. The recycling cart 31 that would have been unable to load more waste foil due to the bulkiness of the waste foil can continue to collect waste foil after compression, greatly increasing the loading capacity of the recycling cart 31, reducing the number of round trips of the recycling cart 31, and improving the overall efficiency of the waste foil recycling.

[0045] To compact the waste foil in the recycling cart 31, please refer to Figure 1In a preferred embodiment, the compression assembly 7 comprises a plurality of pressing rods 71 and a second driving assembly 72, the plurality of pressing rods 71 are respectively rotatably connected to the two sides of the top of the recycling vehicle 31, and the active end of the second driving assembly 72 is connected to the pressing rods 71.

[0046] In use, when the recycling vehicle 31 does not start to collect the waste foil or does not need to perform the compression operation, the pressing rods 71 are in the initial position. At this time, the pressing rods 71 are hung on the two sides of the top of the recycling vehicle 31 through the rotatable connection points. When the waste foil in the recycling vehicle 31 is collected to a certain extent and needs to be compressed, the second driving assembly 72 is started. Since the active end of the second driving assembly 72 is connected to the pressing rods 71, this displacement will exert a force on the pressing rods 71, so that the pressing rods 71 start to rotate around the rotatable connection points on the top of the recycling vehicle 31. With the rotation of the pressing rods 71, the plurality of pressing rods 71 will gradually approach the waste foil inside the recycling vehicle 31. When the pressing rods 71 contact the waste foil, the pressing rods 71 that continue to rotate will exert pressure on the waste foil. Since the plurality of pressing rods 71 are respectively located on the two sides of the top of the recycling vehicle 31, they will simultaneously extrude the waste foil from different directions. The multi-directional extrusion makes the waste foil gradually compressed in the space inside the recycling vehicle 31, and the volume of the waste foil is continuously reduced.

[0047] In order to drive the pressing rods 71 to rotate, please refer to Figure 1 In a preferred embodiment, the second driving assembly 72 comprises a motor 721 arranged on the top of the recycling vehicle 31, a driving worm 722 is arranged on the output shaft of the motor 721, and a driven worm wheel 723 meshing with the driving worm 722 is arranged on the pressing rod 71.

[0048] In use, when it is needed to start the compression assembly 7 to compress the waste foil, the motor 721 is first started. The output shaft starts to rotate, thereby driving the driving worm 722 arranged on the output shaft to rotate. When the driving worm 722 rotates, since it is meshed with the driven worm wheel on the pressing rod 71, the driving worm 722 will transmit the rotary motion to the driven worm wheel 723. The driven worm wheel is fixedly connected with the pressing rod 71, when the driven worm wheel rotates, the pressing rod 71 will rotate together with the driven worm wheel around the rotatable connection points on the top of the recycling vehicle 31. Since the pressing rods 71 are located on the two sides of the top of the recycling vehicle 31, the driven worm wheels on the plurality of pressing rods 71 synchronously rotate under the drive of the driving worm 722, so that all the pressing rods 71 simultaneously move towards the waste foil inside the recycling vehicle 31. With the rotation of the pressing rods 71 towards the waste foil inside the recycling vehicle 31, the pressing rods 71 will gradually contact the waste foil. Under the action of such pressure, the volume of the waste foil is gradually reduced, thereby realizing the compression of the waste foil.

[0049] In order to better understand the present application, the following will be combined with Figure 1 - Figure 3The technical scheme of the waste foil weighing and recycling device is described in detail as follows: the support 11 serves as the main supporting structure of the whole device and provides a stable mounting base for the rotating roller 12. The rotating roller 12 is rotatably connected to the top of the support 11, and the waste foil roll is wound on the rotating roller 12. This arrangement enables the waste foil roll to be conveniently placed on the device, and the rotating roller 12 can freely rotate, facilitating subsequent operations such as unwinding the waste foil during the recycling process. The sensor 21 is arranged at the bottom of the support 11. When the waste foil roll is placed on the rotating roller 12, the circuit inside the sensor 21 converts the physical quantity change caused by the weight into an electrical signal. This electrical signal can accurately reflect the weight information of the waste foil roll, and then transmit the electrical signal to the display 22 connected thereto through a circuit. After receiving the electrical signal transmitted by the sensor 21, the display 22 analyzes and converts the signal through the internal processing circuit, displays the weight value represented by the electrical signal in an intuitive form on the screen, so that the operator can clearly see the real-time weight of the waste foil roll. The recycling cart 31 is used to collect the waste foil recycled from the waste foil roll. Before the recycling process starts, the recycling cart 31 is pushed to the side of the support 11 and passes through the opening 32 arranged on the support 11, ensuring that the recycling cart 31 is in a suitable position to receive the waste foil. When the waste foil roll is recycled, the removed waste foil will directly fall into the recycling cart 31 that has been positioned, realizing the recycling and centralized collection of the waste foil, and facilitating further processing of the waste foil.
