DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0038] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: a kind of heat shrink film machine, fixed frame 1 is connected with servo motor 3 on the top of fixed frame 1, the output of servo motor 3 penetrates fixed frame 1 and is fixedly connected with threaded rod 4, the outside of threaded rod 4 is threadedly connected with movable column 5, the bottom of movable column 5 is fixedly connected with first U-shaped plate 6, the inside of first U-shaped plate 6 is rotatably connected with compression roller 7, the inside top right end of fixed frame 1 is fixedly connected with first cylinder 8, the output of first cylinder 8 is fixedly connected with second U-shaped plate 9, recess 10 is set in the inside of second U-shaped plate 9, the front side of second U-shaped plate 9 is fixedly connected with servo motor 11, the output of servo motor 11 penetrates recess 10 and is fixedly connected with bidirectional screw rod 12, the outer wall of bidirectional screw rod 12 is threadedly connected with movable plate 13 in front and back, the front end of front movable plate 13 is fixedly connected with micro motor 14, the output of micro motor 14 penetrates servo motor 3, the front end of rear movable plate 13 is rotatably connected with movable shaft 16, the adjacent end of movable shaft 16 and the output of micro motor 14 is fixedly connected with clamping plate 15, the inside top left end of fixed frame 1 is provided with dismounting mechanism 2, the front and back of movable column 5 are fixedly connected with sliding block 19, the inside top left side of fixed frame 1 is fixedly connected with multiple slide rods 20, two sliding blocks 19 are slidably connected with the outside of corresponding slide rod 20 respectively, the middle upper portion of two movable plates 13 is slidably connected with the inside of recess 10, the inside right side of fixed frame 1 is fixedly connected with heating box 21, the inside top of heating box 21 is fixedly connected with heating rod 22, the left and right middle portions of heating box 21 are equidistantly fixedly connected with multiple screen curtains 23;

[0039] Specifically, the micro motor 14 can drive the clamping plate 15 to rotate. The special design of the clamping plate 15 allows it to firmly clamp the object, making it rotate with the micro motor 14. At this time, the clamped object is placed in an ideal position, ready for the next film covering work, while the winding roller 203 is also working. Due to the traction of the shrink film, the winding roller 203 will rotate accordingly. This design ensures that the shrink film can smoothly and continuously cover the clamped object, forming a uniform packaging film. This packaging film not only improves the appearance of the product, but also helps to protect the product from external damage. In order to maintain the tension of the shrink film during the packaging process, the threaded rod 4 can be driven to rotate by the servo motor 3. This action makes the movable column 5 move downward along the predetermined trajectory outside the slide rod 20. With the downward movement of the movable column 5, the pressure roller 7 also descends, applying appropriate pressure to the shrink film. This pressure ensures that the shrink film remains tensioned during the packaging process, thereby avoiding loose or non-standard packaging of the packaged product. In addition, this design allows uniform film covering of all sides of the product. By precisely controlling the actions of the micro motor 14 and the servo motor 3, we can ensure that the shrink film can cover every corner of the product, thereby meeting the user's comprehensive needs for product packaging.

[0040] With reference to Figure 1 , Figure 2 and Figure 4 , the disassembly mechanism 2 includes a support plate 201 fixedly connected to the inner top left end of the fixed frame 1, a rotating shaft 202 rotatably connected to the front side of the support plate 201, a winding roller 203 provided on the outer side of the rotating shaft 202, and holes 204 formed on the upper and lower sides of the rotating shaft 202. A spring 205 is fixedly connected to the inside of one side of the hole 204, and a limiting rod 206 is fixedly connected to one end of the spring 205. The distal ends of the two limiting rods 206 are respectively inserted into the upper and lower sides of the winding roller 203.

[0041] Specifically, pressing the limiting rods 206 on both sides can cause the spring 205 to be squeezed, thereby driving the limiting rod 206 into the hole 204. This design cleverly eliminates the limiting fixation of the winding roller 203, making the disassembly and replacement process simple and fast. This design not only simplifies the disassembly and replacement steps, but also improves the convenience of operation. The operator does not need to use complex tools or perform tedious operations, but only needs to press the action to complete the release of the limiting fixation. This not only improves the work efficiency, but also reduces the operation difficulty.

[0042] With reference to Figure 1 and Figure 2The left side of the front end of the fixed frame 1 is fixedly connected with a stepping motor 24, the output end of the stepping motor 24 penetrates the fixed frame 1 and is fixedly connected with a first rotating rod 25, the right side of the inside of the fixed frame 1 is rotationally connected with a second rotating rod 26, the outside of the first rotating rod 25 is provided with a transmission belt 27, and the first rotating rod 25 is in transmission connection with the second rotating rod 26 through the transmission belt 27.

[0043] Specifically, the first rotating rod 25 can be driven to rotate by the stepping motor 24, and the second rotating rod 26 can be driven to rotate by the transmission belt 27, so that the conveying work of the product to be processed can be facilitated.

[0044] Referring to Figure 1 The right side of the front end of the fixed frame 1 is fixedly connected with a controller 28, the controller 28 is electrically connected with the servo motor 3, the first cylinder 8, the servo motor 11, the micro motor 14, the second cylinder 17, the heating rod 22 and the stepping motor 24 respectively, the outside of the controller 28 is provided with a protective cover 29, and one side of the protective cover 29 is rotationally connected with the front end of the fixed frame 1.

[0045] Specifically, the controller 28 can control the work of the servo motor 3, the first cylinder 8, the servo motor 11, the micro motor 14, the second cylinder 17, the heating rod 22 and the stepping motor 24, and the protective cover 29 can protect the controller 28 from being damaged by external factors.

[0046] Referring to Figure 2 The inside of the fixed frame 1 is fixedly connected with the second cylinder 17 at the top, and the output end of the second cylinder 17 is fixedly connected with the cutter 18.

[0047] Specifically, the cutter 18 can be driven to move downward by the second cylinder 17 to cut off the heat shrinkable film, so that the subsequent packaging work of the product can be facilitated.

[0048] Working principle: when the device is used, the product to be processed is placed on the transmission belt 27, then the first rotating rod 25 can be driven to rotate by the stepping motor 24, the second rotating rod 26 can be driven to rotate by the transmission belt 27, so that the transmission belt 27 can start to work, at this time the product can be conveyed to the bottom of the second U-shaped plate 9, then the second U-shaped plate 9 can be driven to move downward by the first cylinder 8 until the movable plate 13 contacts the transmission belt 27, then the bidirectional screw rod 12 can be driven to rotate by the servo motor 11, the movable plate 13 on the outside of the bidirectional screw rod 12 can be driven to move to the middle, so that the clamping plate 15 can be driven to move to the middle to limit and fix the product;

[0049] Then one end of the shrink film outside the winding roller 203 is sequentially threaded through the bottom of the compression roller 7, and then fixed outside the clamped product. At this time, the clamping plate 15 can be driven to rotate by the micro motor 14, and the clamped object will rotate with it. The winding roller 203 will also rotate due to the traction of the shrink film, so that the clamped object can be coated. At the same time, the threaded rod 4 can be driven to rotate by the servo motor 3. At this time, the movable column 5 will move downward outside the sliding rod 20 to drive the compression roller 7 to move downward, so that the shrink film is always in tension when packaging the object, so that the packaged product does not meet the standard, and the film coating work on each surface of the product can be facilitated, thereby meeting the needs of the user.

[0050] After the film coating work is completed, the cutter 18 can be driven downward by the second cylinder 17 to cut off the heat shrink film. Then the coated product can be conveyed to the heating box 21 by the transmission belt 27, and then the product can be heated by the heating rod 22, so that the heat shrink film can be tightly arranged outside the product.

[0051] When the heat shrink film outside the winding roller 203 is used up, the limiting rod 206 on both sides is pressed, and the spring 205 is extruded to drive the limiting rod 206 into the hole 204. At this time, the limiting and fixing of the winding roller 203 can be released, and the winding roller 203 can be easily disassembled and replaced, thereby improving the practicability of the device.

[0052] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
