Description

Technical Field

[0001] This application relates to the field of film wrapping equipment technology, and in particular to a material stacking film wrapping equipment. Background Technology

[0002] Currently, plastic granules are collected and packaged in collection bags, and multiple collection bags are stacked on palletizing racks to form unit stacks. This centralized storage and stacking method greatly improves the convenience of logistics and transportation and the utilization rate of warehouse space. To ensure that the stacks are not damaged during transportation and storage, protective film needs to be wrapped around them. This not only prevents dust and moisture from corroding the materials but also enhances the stability of the stacks. Traditional film wrapping methods use a rotating base, on which the stack is placed, with a film roll rack located beside it. The rotating base rotates in conjunction with the unwinding of the film roll on the rack for the film wrapping operation. However, existing film roll racks typically only have a single film roll. When the stack needs to be wrapped with protective film of different materials, the film roll needs to be disassembled and reassembled, resulting in low wrapping efficiency. Therefore, further improvements are needed. Utility Model Content

[0003] In order to improve the wrapping efficiency of material stacks, this application provides a material stack wrapping device.

[0004] The material stack wrapping device provided in this application adopts the following technical solution:

[0005] A material stack wrapping device includes an annular guide rail, several mounting columns disposed on the annular guide rail, and a sliding seat slidably connected to the annular guide rail. The annular guide rail is located above the material stack. The sliding seat is provided with traveling wheels slidably connected to the annular guide rail, and a traveling drive component is provided on the sliding seat to drive the traveling wheels to rotate. The sliding seat is provided with a film roll for wrapping the material stack. A material changing frame is rotatably connected below the sliding seat. The sliding seat is provided with a switching drive component to drive the material changing frame to rotate around its own axis. Multiple film rolls are provided and distributed around the axis of the material changing frame, and the protective film material on each film roll is different.

[0006] By adopting the above technical solution, the material stack is placed below the center of the annular guide rail. After fixing one end of the protective film roll to the outer wall of the material stack, the traveling drive unit drives the traveling wheels to rotate, so that the traveling wheels move along the path of the annular guide rail. This allows the sliding seat to move around the outer periphery of the material stack. During the sliding process of the sliding seat, the protective film on the film roll is pulled and automatically unwound, realizing the film wrapping operation on the outer periphery of the material stack. When different protective film materials need to be wrapped, the film rolls of different protective film materials can be switched by driving the material changing frame to rotate through the switching drive unit, thereby improving the film wrapping efficiency of the material stack.

[0007] Preferably, the outer and inner peripheral walls of the annular guide rail are provided with travel grooves, and two travel wheels are provided and distributed radially along the annular guide rail. The travel wheels are located above the sliding seat, and the outer peripheral walls of the two travel wheels abut against the inner peripheral wall of the travel groove, and the lower end face of the travel wheels abuts against the bottom inner wall of the travel groove.

[0008] By adopting the above technical solution, the traveling grooves opened on the outer and inner peripheral walls of the annular guide rail, together with two traveling wheels distributed radially along the annular guide rail, can ensure that the outer peripheral wall of the traveling wheel abuts against the inner peripheral wall of the traveling groove and the lower end face abuts against the bottom inner wall of the traveling groove, thereby improving the stability of the traveling wheel movement. This makes the sliding seat move more smoothly around the outer periphery of the material stack, making the film wrapping operation more stable and reliable.

[0009] Preferably, the bottom inner wall of the walking groove is provided with ball bearings, and the lower end face of the walking wheel abuts against the ball bearings.

[0010] By adopting the above technical solution, ball bearings are installed on the inner wall of the bottom of the travel groove and the lower end face of the travel wheel abuts against the ball bearings, which can reduce the friction between the travel wheel and the inner wall of the bottom of the travel groove.

[0011] Preferably, the material changing rack includes an upper plate rotatably connected to the lower end face of the sliding seat, a lower plate located below the upper plate and coaxial with the upper plate, and a fixing rod fixedly connected between the upper plate and the lower plate. Multiple fixing rods are provided and distributed around the axis of the upper plate. The film roll is located between the upper plate and the lower plate. The upper plate and / or the lower plate are provided with a limiting rod that slides into the core hole of the film roll.

[0012] By adopting the above technical solution, the material changing frame consists of an upper plate, a lower plate, and multiple fixing rods. The film roll is located between the upper plate and the lower plate. The limiting rods of the upper plate and / or the lower plate are slidably inserted into the core hole of the film roll, which can stably install the film roll and prevent the film roll from shaking or shifting during the film wrapping process.

[0013] Preferably, the limiting rod is slidably inserted into the lower plate, and the lower plate is provided with an elastic element that forces the upper part of the limiting rod to slide and insert into the membrane core hole under normal conditions.

[0014] By adopting the above technical solution, the limiting rod slides through the lower plate, and the elastic element forces the upper part of the limiting rod to insert into the core hole of the film roll under normal conditions, ensuring the installation stability of the film roll on the material changing rack and preventing the film roll from shaking or shifting during the wrapping process.

[0015] Preferably, the lower end of the limiting rod is fixedly connected to a force-applying plate located below the lower plate, and the elastic element is a spring sleeved on the limiting rod. One end of the spring is fixedly connected to the lower end face of the lower plate, and the other end of the spring is fixedly connected to the upper end face of the force-applying plate.

[0016] By adopting the above technical solution, the spring force can be overcome by pressing the force plate, causing the limiting rod to disengage from the membrane roll core hole, which facilitates the replacement of the membrane roll.

[0017] Preferably, a lifting platform is provided below the annular guide rail, and the lifting platform is used to place the material stack.

[0018] By adopting the above technical solution, the material stack is placed on the lifting platform, and the height of the material stack can be adjusted as needed. When the sliding seat moves around the outer perimeter of the material stack, the film roll can be wrapped more flexibly and comprehensively.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. Place the material stack below the center of the circular guide rail. After fixing one end of the protective film of the film roll to the outer wall of the material stack, drive the traveling wheel to rotate through the traveling drive component. This causes the traveling wheel to move along the path of the circular guide rail, thereby enabling the sliding seat to move around the outer perimeter of the material stack. During the sliding process of the sliding seat, the protective film on the film roll is pulled and automatically unwound, realizing the film wrapping operation on the outer perimeter of the material stack. When different protective film materials need to be wrapped, the film rolls of different protective film materials can be switched by driving the material changing frame to rotate through the switching drive component, thereby improving the film wrapping efficiency of the material stack.

[0021] 2. Place the material stack on the lifting platform. The height of the material stack can be adjusted as needed. When the sliding seat moves around the outer perimeter of the material stack, the film roll can be wrapped more flexibly and comprehensively. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] Example 1:

[0029] This application discloses a material stack wrapping device, referring to... Figure 1 The system includes an annular guide rail 1, several mounting columns 2 disposed on the annular guide rail 1, and a sliding seat 3 slidably connected to the annular guide rail 1.

[0030] Reference Figure 2 The annular guide rail 1 has travel grooves 12 on both its outer and inner peripheral walls, making its cross-section I-shaped. Ball bearings are installed on the bottom inner wall of the travel grooves 12. A sliding seat 3 is located below the annular guide rail 1. A traveling wheel 31, slidably connected to the travel groove 12, is installed on the upper surface of the sliding seat 3. The traveling wheel 31 is vertically oriented, and there are two traveling wheels 31 distributed radially along the annular guide rail 1. The outer peripheral wall of the traveling wheel 31 abuts against the inner peripheral wall of the travel groove 12, and the lower end face of the traveling wheel 31 abuts against the ball bearings.

[0031] Reference Figure 2 , Figure 3 The sliding seat 3 has a mounting cavity, and the traveling wheel 31 is coaxially and fixedly connected to a first rotating shaft 32 that rotatably passes through the top wall of the sliding seat 3 and extends into the mounting cavity. The two first rotating shafts 32 are driven by a synchronous gear set, which is located between the sliding seat 3 and the annular guide rail 1. The sliding seat 3 is provided with a traveling drive component that drives one of the first rotating shafts 32 to rotate. In this embodiment, the traveling drive component is a first motor 33, which is fixedly connected to the outer wall of the sliding seat 3. The output shaft of the first motor 33 is horizontally arranged and rotatably passes through the side wall of the sliding seat 3 and extends into the mounting cavity. The output shaft of the first motor 33 and the first rotating shaft 32 are driven by a bevel gear set.

[0032] A second rotating shaft 34 is rotatably connected to the lower end face of the sliding seat 3, and the second rotating shaft 34 is vertically arranged. A material changing frame 4 is coaxially fixedly connected to the lower part of the second rotating shaft 34. Specifically, the material changing frame 4 includes an upper plate 41 coaxially fixedly connected to the lower part of the second rotating shaft 34, a lower plate 42 located below the upper plate 41 and coaxial with the upper plate 41, and a fixing rod 43 fixedly connected between the upper plate 41 and the lower plate 42. Three fixing rods 43 are provided and distributed around the axis of the upper plate 41. A film roll 5 for wrapping the material stack is detachably connected between the upper plate 41 and the lower plate 42. Multiple film rolls 5 are provided and distributed around the axis of the material changing frame 4. In this embodiment, the protective film on each film roll 5 is made of different materials. In this embodiment, three film rolls 5 are provided, and the film rolls 5 and the fixing rods 43 are staggered. Waterproof film rolls 5, fireproof film rolls 5, or UV-resistant film rolls 5 can be used.

[0033] The sliding seat 3 is equipped with a switching drive component that drives the second rotating shaft 34 to rotate around its own axis. The switching drive component is a second motor 35, specifically a servo motor. The second motor 35 is fixedly connected to the outer wall of the sliding seat 3, and the output shaft of the second motor 35 is vertically arranged. The output shaft of the second motor 35 and the second rotating shaft 34 are connected by a synchronous belt.

[0034] The upper plate 41 and / or the lower plate 42 are provided with a limiting rod 44 that slides into the core hole of the membrane roll 5. In this embodiment, both the upper plate 41 and the lower plate 42 are provided with limiting rods 44. Taking the lower plate 42 as an example, the limiting rod 44 slides through the lower plate 42. The lower plate 42 is provided with an elastic element that forces the upper part of the limiting rod 44 to slide into the core hole of the membrane roll 5 under normal conditions. The lower end of the limiting rod 44 is fixedly connected to a force-applying plate 45 located below the lower plate 42. The elastic element is a spring 46 sleeved on the limiting rod 44. One end of the spring 46 is fixedly connected to the lower end face of the lower plate 42, and the other end of the spring 46 is fixedly connected to the upper end face of the force-applying plate 45. Limiting frames 47 are fixedly connected to the upper end face of the upper plate 41 and the lower end face of the lower plate 42. The limiting frames 47, the upper plate 41, and the lower plate 42 all have rope holes. A connecting rope 48 is fixedly connected between the upper end face of the force-applying plate 45 on the upper plate 41 and the lower end face of the force-applying plate 45 on the lower plate 42. The connecting rope 48 passes through the rope holes. By pulling the connecting rope 48 located between the upper plate 41 and the lower plate 42, the limiting rod 44 can be forced to slide away from the membrane roll 5, causing the limiting rod 44 to disengage from the core hole of the membrane roll 5, allowing the membrane roll 5 to be replaced. In other embodiments, the limiting rod 44 can be slid by a cylinder.

[0035] The implementation principle of the material stack wrapping device in this application embodiment is as follows: the material stack is placed below the center of the annular guide rail 1, and one end of the protective film of the film roll 5 is fixed to the outer wall of the material stack. The walking drive component drives the walking wheel 31 to rotate, so that the walking wheel 31 moves along the path of the annular guide rail 1, thereby realizing the movement of the sliding seat 3 around the outer periphery of the material stack. During the sliding process of the sliding seat 3, the protective film on the film roll 5 is pulled and automatically unwound, realizing the wrapping operation on the outer periphery of the material stack and improving the wrapping efficiency of the material stack.

[0036] When it is necessary to switch the film roll 5 to different protective film materials for the wrapping operation, the switching drive unit drives the material changing frame 4 to rotate, so that the film roll 5 to be operated can be transferred to the wrapping station.

[0037] Example 2:

[0038] The difference from Example 1 is that, referring to Figure 4 A lifting platform 6 is provided below the annular guide rail 1. The lifting platform 6 is placed on the ground. In this embodiment, the lifting platform 6 is a scissor-type lifting platform 6. The material stack is placed on the upper surface of the lifting platform 6 by a forklift. The height of the material stack can be adjusted as needed. When the sliding seat 3 moves around the outer periphery of the material stack, the film roll 5 can be wrapped more flexibly and comprehensively.

[0039] 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.
