[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0027] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0028] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-3As shown, it illustrates a CPE film tray wrapping machine according to an embodiment of the present invention, including a device body 1, a precision calibration component 2 fixed on the side of the device body 1, a lifting seat 4 slidably connected inside the device body 1, and a replacement component 3 fixed at the bottom of the lifting seat 4.

[0033] The calibration component 2 includes a base plate 21, a first motor 22 fixed to the top of the base plate 21, a drive gear 23 fixed to the output end of the first motor 22, racks 24 meshing with both sides of the drive gear 23, a connecting plate 25 fixed to the side of the racks 24, and a clamping plate 26 fixed to the top of the connecting plate 25. The clamping plate 26 moves by meshing with the drive gear 23 through the racks 24 on the side of the connecting plate 25.

[0034] In some examples, a groove 28 is provided inside the base plate 21, and a positioning rod 29 is fixed in the groove 28. A limiting ring 27 is slidably connected to the positioning rod 29. The limiting ring 27 is fixed to the side of the rack 24. The limiting ring 27 cooperates with the positioning rod 29 so that when the rack 24 moves, the limiting ring 27 slides in the positioning rod 29, so that the rack 24 will not deviate during the movement.

[0035] Two sets of clamping plates 26 are provided, and the two sets of clamping plates 26 are symmetrically distributed on both sides of the base plate 21. Each set of clamping plates 26 is slidably connected to an mounting block 212. When the two sets of clamping plates 26 move towards each other, they can clamp the wrapped film, thereby preventing the film from shifting or wrinkling during subsequent cutting.

[0036] For example, such as Figure 3 As shown, after the stretch film is wrapped around the goods, the first motor 22 is controlled by the control button on the main body 1 to drive the drive gear 23 to mesh with the rack 24. This causes the clamping plates 26 on both sides of the base plate 21 to mesh with the drive gear 23 through the rack 24, causing the clamping plates 26 to move towards each other. This clamping plates 26 clamp the stretch film, thereby fixing the stretch film and improving the subsequent cutting accuracy.

[0037] like Figures 1-4 As shown, this invention illustrates a CPE film tray wrapping machine according to another embodiment of the present invention. The machine includes a clamping plate 26 with a lifting groove 210 on its side. A lifting rod 211 is fixed in the lifting groove 210. An mounting block 212 is fixed on the side of the lifting rod 211. A limiting block 213 is installed in the mounting block 212. A cutting tool 214 is fixed on the side of the limiting block 213. An extension block 215 is fixed on the side of the cutting tool 214 away from the limiting block 213. A limiting rod 216 is fixed on the side of the extension block 215.

[0038] In some examples, a limiting groove 217 is fixed to the side of the mounting block 212 in another set of clamping plates 26. A pressure sensor 218 is fixed in the limiting groove 217. The pressure sensor 218 is a 1MPaA-CPS32 type sensor. When the limiting rod 216 is inserted into the limiting groove 217, the pressure sensor 218 can detect the pressure, so that the lifting rod 211 is controlled by the PLC to rotate through the power supply, thereby allowing the cutting tool 214 to perform cutting work. When the limiting rod 216 is inserted into the limiting groove 217, it means that the cutting tool 214 is fixed. The limiting groove 217 is made of a malleable material, so that the limiting rod 216 can be installed and removed.

[0039] A limiting bolt 219 is inserted between the mounting block 212 and the limiting block 213. The limiting bolt 219 is used to install and fix the cutting tool 214, so that the cutting tool 214 can be installed in the mounting block 212, making it easy to disassemble and replace the cutting tool 214.

[0040] The end of the limiting rod 216 is round, and the end of the limiting groove 217 is hollow. The shapes of the limiting rod 216 and the limiting groove 217 are matched.

[0041] For example, such as Figure 4 As shown, after the clamping plate 26 stably clamps the stretch film, the limiting rod 216 at the other end of the extension block 215 on the side of the cutting tool 214 is inserted through the limiting groove 217 fixed on the mounting block 212 in another set of clamping plates 26, so that the cutting tool 214 can be stably fixed in the mounting block 212. At the same time, the pressure sensor 218 detects the pressure, so that the PLC controls the power supply to drive the mounting block 212 to rise and fall in the lifting rod 211, thereby allowing the cutting tool 214 to cut the stretch film. When it is necessary to replace the cutting tool 214 according to different film thicknesses, firstly, the clamping plate 26 stops clamping the stretch film, so that the limiting rod 216 separates from the limiting groove 217. Then, by pulling out the limiting bolt 219 from the mounting block 212 and the limiting block 213, the cutting tool 214 can be disassembled and removed from the mounting block 212, thereby replacing the cutting tool 214.

[0042] Example 2

[0043] like Figures 1-5 As shown, it illustrates a CPE film tray wrapping machine in another embodiment of the present invention.

[0044] In some examples, the replacement component 3 includes a support plate 31, a second motor 32 fixed to the bottom of the support plate 31, a sprocket 33 fixed to the output end of the second motor 32, a chain 34 meshing with the side of the sprocket 33, a mounting post 35 rotatably connected to the top of the chain 34, a membrane roll 36 installed in the mounting post 35, and the circumference of the chain 34 being four times that of the sprocket 33. The second motor 32 is controlled by a control button on the device body 1. When the control button is pressed, the second motor 32 drives the sprocket 33 to rotate two revolutions, causing the mounting post 35 on one side of the chain 34 to rotate to the other side.

[0045] Both ends of the chain 34 are rotatably connected to mounting posts 35. There are two sets of mounting posts 35, and each set of mounting posts 35 is equipped with a membrane roll 36. When one set of membrane rolls 36 is in use, the other set of membrane rolls 36 is kept on standby.

[0046] For example, such as Figure 5 As shown, when one set of film rolls 36 in the mounting column 35 is used up, the second motor 32 is controlled to rotate by the control button on the device body 1. The second motor 32 drives the sprocket 33 to mesh with the chain 34, so that another set of film rolls 36 moves to replace the used film rolls 36 and continue to wind. Then, the workers can replace the used film rolls 36 in the mounting column 35. This allows the used film rolls 36 to be replaced while the goods are being wound, which not only saves the time that the workers need to stop the device body 1 to replace them, but also improves the efficiency of winding goods.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
