Description

Technical Field

[0001] This utility model relates to the field of conveying equipment, and more particularly to a conveying device for plastic film rolls. Background Technology

[0002] Plastic film rolls refer to products packaged and sold in roll form. The common packaging unit for plastic film rolls is the "roll". This packaging form is convenient for storage, transportation and use, especially on large machines or production lines that require continuous packaging. Plastic film roll conveying devices are equipment specifically designed for transporting and handling plastic film rolls, which can improve transportation efficiency, protect film rolls from damage, and reduce the labor intensity of operators.

[0003] A search revealed that CN221316282U discloses a conveying device for plastic film rolls, aiming to solve the technical problem that current conveying devices can only transport a small amount of plastic film rolls at a time, resulting in low conveying efficiency. The device includes a cargo box, on which multiple interlocking plates for embedding plastic film rolls are symmetrically installed at equal intervals on the sides. Each of the interlocking plates has a through groove. A U-shaped plate is installed on the side of the cargo box to surround the cargo box. Two rollers are symmetrically installed on one side of the bottom of the cargo box, and a guiding device is installed on the other side of the bottom of the cargo box. The guiding device includes a rectangular frame, and wheels are installed on both sides of the rectangular frame.

[0004] Existing plastic film roll conveying devices mostly adopt a fixed design, with the spacing of key components used to embed the film roll being preset to a fixed value. This makes it impossible to adjust the spacing of the structure in real time according to the diameter of the film roll, resulting in low adaptability when handling plastic film rolls of different diameters. When it is necessary to convey both small-diameter and large-diameter film rolls at the same time, existing conveying devices often cannot meet the needs of both and can only perform single-specification operations, which increases production and time costs. Utility Model Content

[0005] To solve the problems mentioned above, this utility model achieves its goals through the following technical solution:

[0006] A conveying device for plastic film rolls includes: a base plate; and a plurality of placement mechanisms mounted on the base plate, wherein the placement mechanisms are configured to move on the base plate to adjust the spacing between the plurality of placement mechanisms for placing plastic film rolls of different diameters; each placement mechanism includes a movable plate and two placement racks, the movable plate being mounted on the base plate and the two placement racks being connected to the movable plate and configured to be close to or far apart from each other for placing plastic film rolls of different lengths.

[0007] The movable plate includes two adjustment slots formed on the movable plate, and two placement racks respectively connected to the two adjustment slots.

[0008] The placement mechanism further includes two first elastic elements, one end of which is connected to the inner wall of the adjustment groove and the other end of which is connected to the placement frame. The first elastic elements are used to provide the placement frame with an initial position restoring force.

[0009] It also includes: a material roller, installed between two placement frames, the projection shape of which is U-shaped, for providing placement space for the material roller; two side plates, installed on the base plate and arranged symmetrically; and a control mechanism, located on the side plates, for controlling the movement of the material roller on the placement frames.

[0010] The control mechanism includes: a movable frame mounted on two side plates; two control plates connected within the movable frame, configured to simultaneously move closer to or further away from each other; two connecting plates connected to the movable frame and connected to the control plates; a connecting rod, one end of which passes through the movable frame and connects to the connecting plate, and the other end of which is connected to the control plate; and a second elastic element, one end of which is connected to the control plate and the other end of which is connected to the movable frame. The second elastic element provides a restoring force for the control plates to maintain their initial position, causing the control plates to conform to one side of the placement frame.

[0011] It also includes: a power source, installed on the side plate; and a lead screw, one end of which passes through the movable frame and the other end of which is connected to the power shaft of the power source.

[0012] This invention provides a conveying device for plastic film rolls. Compared with the prior art, it has the following advantages:

[0013] 1. By designing a movable placement mechanism and an adjustable-spacing placement rack, the device can adjust the spacing in real time according to plastic film rolls of different diameters, enabling simultaneous transport of film rolls of different specifications. This improves the adaptability and flexibility of the device and meets diverse production needs.

[0014] 2. The U-shaped placement frame provides a stable and suitable placement space for the material rollers, effectively preventing them from rolling or shifting during transportation. The first elastic element ensures that the placement frame can automatically return to its initial position after adjusting the spacing or unloading the material rollers, enhancing the stability and safety of transportation. The control board can precisely control the position of the material rollers by driving the lead screw through the power source, achieving fast and accurate material discharge operation.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Reference Figures 1-4A conveying device for plastic film rolls includes: a base plate 1; a plurality of placement mechanisms 3 mounted on the base plate 1, the placement mechanisms 3 being movable on the base plate 1 to adjust the spacing between the plurality of placement mechanisms 3 for placing plastic film rolls of different diameters; each placement mechanism 3 includes a movable plate 301 and two placement racks 302, the movable plate 301 being mounted on the base plate 1, and the two placement racks 302 being connected to the movable plate 301 and configured to move closer to or further away from each other for placing plastic film rolls of different lengths; the movable plate 301 includes: two adjusting grooves 303 formed on the movable plate 301, the two placement racks 302 being respectively connected to the two adjusting grooves 303; and two first elastic members 304, one end of which is connected to the inner wall of the adjusting groove 303, and the other end of which is connected to the placement rack 302. On 02, the first elastic element 304 provides the initial position restoring force for the placement rack 302. The movable plate 301 is mounted on the base plate 1 and designed to be movable, which facilitates the adjustment of the spacing according to plastic film rolls of different diameters, improving the adaptability and flexibility of the device. The two placement racks 302 can move closer or further apart from each other through the adjustment groove 303 connected to the movable plate 301, so that the device can accommodate plastic film rolls of different lengths, enhancing its practicality. The first elastic element 304 provides the initial position restoring force for the placement rack 302, ensuring that the placement rack 302 can automatically return to the initial position after adjusting the spacing or unloading the material roller 4, which is convenient for the next use and increases the convenience of operation. The first elastic element 304 is a stainless steel spring, but an alloy spring can also be used.

[0028] Reference Figure 2 The material roller 4 is installed between two placement racks 302. The projection shape of the placement racks 302 is U-shaped, which is used to provide placement space for the material roller 4. The two side plates 2 are installed on the base plate 1 and are arranged symmetrically. As the direct bearing components of the plastic film roll, their U-shaped projection shape provides a stable and suitable placement space for the material roller 4, effectively preventing the material roller 4 from rolling or shifting during transportation, ensuring the safety of transportation, and the placement rack 302 allows multiple material rollers 4 to be stacked.

[0029] Reference Figure 1 and Figure 4A control mechanism 5, mounted on the side plate 2, is used to control the movement of the material roller 4 on the placement frame 302. The control mechanism 5 includes: a moving frame 501 mounted on the two side plates 2; two control plates 502 connected within the moving frame 501, configured to move simultaneously closer to or further away from each other; two connecting plates 503 connected to the moving frame 501, with the connecting plates 503 connected to the control plates 502; a connecting rod 504, one end of which passes through the moving frame 501 and connects to the connecting plate 503, and the other end connected to the control plate 502; a second elastic element 505, one end of which is connected to the control plate 502, and the other end connected to the moving frame 501. The second elastic element 505 provides a restoring force to the control plate 502 to its initial position, causing the control plate 502 to adhere to one side of the placement frame 302. The power source 6 is installed on the side plate 2; the lead screw 601 has one end passing through the moving frame 501 and the other end connected to the power shaft of the power source 6. Through the elastic action of the second elastic element 505, the control plate 502 can be driven to fit against one side of the placement frame 302. Even if the position of the placement frame 302 changes, the control plate 502 can also move and contact it. When the moving frame 501 moves upward, it drives the control plate 502 to move together. The control plate 502 can lift the material roller 4 protruding from one side of the placement frame 302 to facilitate the discharge of the material roller 4. The power source 6 drives the lead screw 601 to rotate, and the lead screw 601 can drive the moving frame 501 to move on the side plate 2. The power source 6 is a servo motor or a stepper motor. The second elastic element 505 is a stainless steel spring or an alloy spring.

[0030] During use, the placement mechanism 3 adjusts the position of the moving plate 301 on the base plate 1 and the relative distance between the two placement frames 302 on the moving plate 301 according to the diameter and length of the plastic film roll to be transported, to accommodate different specifications of rollers 4. The first elastic element 304 maintains the placement frame 302 in a certain degree of stability after adjustment and is ready to automatically return to the initial position when needed. The roller 4 is placed between the two placement frames 302. The U-shaped structure of the placement frame 302 provides stable support and restraint for the roller 4, preventing it from rolling or shifting during transportation. If multiple rollers 4 need to be stacked, they can be placed on top of the first roller 4 according to the load-bearing capacity and stability of the placement frame 302. The device will not move or slip during transportation due to vehicle vibration or other external factors. When removing the material roller 4, the power source 6 of the control mechanism 5 is first activated. The power source 6 drives the lead screw 601 to rotate. The lead screw 601 drives the moving frame 501 to move vertically on the side plate 2 through the connecting rod 504 and the connecting plate 503. As the moving frame 501 rises, the control plate 502 inside it also moves. Due to the effect of the second elasticity, the control plate 502 always fits against one side of the placement frame 302. Even if the position of the placement frame 302 changes slightly, the control plate 502 can maintain contact. When the control plate 502 contacts the material roller 4 protruding from one side of the placement frame 302, as the moving frame 501 continues to rise, the control plate 502 will lift the material roller 4, making it detach from the support of the placement frame 302 for easy removal. After removing all the required material rollers 4, the position and spacing of the placement mechanism 3 can be adjusted as needed to place new material rollers 4.

[0031] In summary, compared with existing technologies, it has the following beneficial effects:

[0032] By designing a movable placement mechanism 3 and an adjustable-spacing placement rack 302, the device can adjust the spacing in real time according to plastic film rolls of different diameters, enabling simultaneous transport of film rolls of different specifications. This improves the adaptability and flexibility of the device and meets diverse production needs.

[0033] The U-shaped placement frame 302 provides a stable and suitable placement space for the material roller 4, effectively preventing the material roller 4 from rolling or shifting during transportation. The first elastic element 304 ensures that the placement frame 302 can automatically return to its initial position after adjusting the spacing or unloading the material roller 4, enhancing the stability and safety of transportation. The control board 502 can precisely control the position of the material roller 4 by driving the lead screw 601 to rotate through the power source 6, achieving fast and accurate material discharge operation.
