Description

Technical Field

[0001] This utility model relates to the field of film roll production technology, and in particular to a film roll adjustment and flipping device. Background Technology

[0002] In the packaging industry, packaging films supplied in rolls are collectively referred to as roll film. Simply put, it's packaging film rolled up. Common types of roll film include PVC shrink film rolls, OPP rolls, PE rolls, PET protective film, and composite rolls. After production, roll film needs to be flipped and rearranged. During the production of roll film products, as the width and length of the roll increase, the maximum weight of a single roll can reach 120 kg. This flipping and rearranging of roll film is impossible to perform manually and often requires several people working together. Furthermore, roll film is frequently damaged. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the existing technology, this utility model provides a roll film adjustment and flipping device. Its purpose is to solve the problems in the production of roll film products, such as the fact that as the width of the roll film and the number of meters wound up increase, the maximum weight of a single roll film can reach 120Kg, making it impossible for manual roll film to be flipped and adjusted, often requiring several people to work together, and the roll film is often damaged.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A film roll adjustment and flipping device includes a frame, a cylinder, bearing seats, a rotating shaft, a connecting rod, a connecting frame, and an air shaft. The cylinder is hinged to the frame, and two symmetrically arranged bearing seats are fixedly installed on the frame. A rotating shaft is rotatably connected between the two bearing seats, and a connecting rod is fixedly connected to the rotating shaft. The piston rod of the cylinder is hinged to one end of the connecting rod. A connecting frame is fixedly connected to the rotating shaft, and an air shaft is fixedly connected to the connecting frame.

[0006] Furthermore, the frame includes two symmetrically arranged channel steels, a fixing rod is fixedly arranged between the two channel steels, a fixing plate is fixedly welded to the top of the channel steels, and the two bearing seats are respectively fixedly installed on the top of the two channel steels.

[0007] Furthermore, it also includes trachea A, trachea B, trachea C, a first reversing valve, a second reversing valve, and an air source.

[0008] Furthermore, the air pipe A is connected to the air shaft, and the end of the air pipe A away from the air shaft is connected to the first reversing valve.

[0009] Furthermore, the air pipe B is connected to one end of the cylinder, and the end of the air pipe B away from the cylinder is connected to the second reversing valve.

[0010] Furthermore, the air pipe C is connected to the end of the cylinder away from the air pipe B, and the end of the air pipe C away from the cylinder is connected to the second reversing valve.

[0011] Furthermore, the first directional valve is a two-position three-way directional valve.

[0012] Furthermore, the second directional valve is a two-position four-way directional valve.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model discloses a film roll adjustment and flipping device that uses a forklift to assist in adjusting and flipping the film roll.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0021] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0022] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figures 1 to 3As shown, a film roll adjustment and flipping device includes a frame 1, a cylinder 2, a bearing seat 3, a rotating shaft 4, a connecting rod 5, a connecting frame 6, and an air shaft 7.

[0024] The frame 1 includes two symmetrically arranged channel steels 8, a fixing rod 9 is fixedly installed between the two channel steels 8, a fixing plate 10 is fixedly welded to the top of the channel steels 8, and two bearing seats 3 are respectively fixedly installed on the top of the two channel steels 8.

[0025] When the equipment is in use, the two forks of the forklift can be inserted into the two channel steels 8 respectively, and the forklift can drive the frame 1 to move up and down.

[0026] A cylinder 2 is hinged to a frame 1. Two symmetrically arranged bearing seats 3 are fixedly installed on the frame 1. A rotating shaft 4 is rotatably connected between the two bearing seats 3. A connecting rod 5 is fixedly connected to the rotating shaft 4. The piston rod of the cylinder 2 is hinged to one end of the connecting rod 5. A connecting frame 6 is fixedly connected to the rotating shaft 4. An air expansion shaft 7 is fixedly connected to the connecting frame 6.

[0027] The film roll adjustment and flipping device also includes air pipe A11, air pipe B12, air pipe C13, a first reversing valve 14, a second reversing valve 15, and an air source 16. The first reversing valve 14 is a two-position three-way reversing valve, and the second reversing valve 15 is a two-position four-way reversing valve. The air source 16, the first reversing valve 14, and the second reversing valve 15 are installed on a forklift, and the air source 16 is connected to the first reversing valve 14 and the second reversing valve 15.

[0028] The trachea A11 is connected to the air shaft 7. The end of the trachea A11 away from the air shaft 7 is connected to the first reversing valve 14. The first reversing valve 14 controls the expansion and contraction of the air shaft 7.

[0029] Air pipe B12 is connected to one end of cylinder 2, and the end of air pipe B12 away from cylinder 2 is connected to the second reversing valve 15. Air pipe C13 is connected to the end of cylinder 2 away from air pipe B12, and the end of air pipe C13 away from cylinder 2 is connected to the second reversing valve 15. The second reversing valve 15 controls the movement of cylinder 2.

[0030] When adjusting and flipping the film roll, the air shaft 7, as... Figure 1 In the horizontal position shown, the forklift forks are inserted into the channel steel 8. The movement of the forklift forces the air shaft 7 into the film roll. The first reversing valve 14 controls the expansion of the air shaft 7, securing the film roll. The forklift forks then lift the frame 1. The second reversing valve 15 reverses the direction, causing the cylinder 2 to move the connecting rod 5. The connecting rod 5 then rotates the rotating shaft 4, which in turn causes the connecting frame 6 and the air shaft 7 to flip. Figure 2 In the vertical position shown, the air shaft 7 drives the film roll to flip, and the film roll flips 90°. The forklift then transports the film roll to the designated location. The first reversing valve 14 reverses, the air shaft 7 exhausts air, and the forklift drives the frame 1 to rise, thus completing the film roll adjustment and flipping.

[0031] It is worth noting that in this embodiment, the air shaft 7 is a 6-inch keyed air shaft, and the air source 16, the two-position three-way reversing valve, and the two-position four-way reversing valve are all existing technologies, which will not be described in detail here.
