Description

Technical Field

[0001] This utility model relates to the field of film winding machine technology, specifically a film winding machine capable of continuous winding. Background Technology

[0002] Film wrapping machines, also known as wrapping machines, are widely used in foreign trade exports, food and beverage production, canning, papermaking, dyeing and other products to meet the packaging requirements of containerized storage, transportation and mechanized loading and unloading operations. They help reduce the cost of containerized products, improve production efficiency, prevent damage to goods during handling, and provide dustproof, moisture-proof and cleanliness protection.

[0003] The existing Chinese utility model patent with publication number CN220721481U discloses a film wrapping machine, including a chassis, a loading tray rotatably connected to the chassis, a drive motor mounted on the chassis, and a wrapping assembly. A turntable rotatably rotates around the outer periphery of the loading tray on the chassis. The wrapping assembly is disposed on the turntable and located on the outer periphery of the loading tray. A linkage assembly is connected between the drive motor, the loading tray, and the turntable to drive the turntable and the loading tray to rotate coaxially and in opposite directions. This utility model has the following advantages and effects: the film wrapping machine has higher wrapping efficiency, longer service life, and convenient operation.

[0004] In the above-mentioned film wrapping machine design, by installing an adjusting component on the film frame, the problem of low efficiency of the film wrapping machine with unidirectional rotation of the loading tray was successfully solved. However, in actual operation, this existing film wrapping machine often runs out of film when the wrapping operation is halfway completed. This requires the operator to manually replace the film roll, which not only affects the continuity and efficiency of film wrapping, but also brings inconvenience to the operation. Utility Model Content

[0005] The purpose of this invention is to overcome the problem of inconvenience in connecting and winding existing technology, and to provide a film winding machine that can be continuously wound.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A continuously winding film wrapping machine, comprising:

[0008] A support plate has two support blocks fixedly installed on both sides of one side. The support blocks are L-shaped. A sensor is fixedly installed in the middle of one side of each support block. A push rod is slidably connected inside the support block. A limit plate is fixedly installed on one side of the push rod. A return spring is fixedly installed on one side of the limit plate. A pull ring is fixedly installed on the other side of the limit plate. Two connecting plates are fixedly installed on both sides of the support plate. Two electric push columns are fixedly installed on both sides inside the connecting plates. A heating device is fixedly installed on one side of each electric push column. A clamping frame is fixedly installed in the middle of one side of the heating device. The clamping frame is C-shaped. An electric push rod is fixedly installed on one side of the clamping frame. A clamping plate is fixedly installed on one side of the electric push rod.

[0009] In a preferred embodiment, two rotating disks are rotatably connected to the top two sides of the support plate, and an air shaft is rotatably connected to the top of the rotating disks. The air shaft is a structure used to clamp the film roll.

[0010] In a preferred embodiment, a film roll is clamped and connected to the outer side of the air shaft.

[0011] In a preferred embodiment, a support frame is fixedly installed on one side of the support plate. The support frame is in the shape of a "C" and is a structure used for support.

[0012] In a preferred embodiment, two rubber rollers are rotatably connected to the center of the support frame, and guide rollers are rotatably connected to both sides of the support frame. The guide rollers are structures used for guidance.

[0013] In a preferred embodiment, an electric lifting frame is slidably connected to one side of the support frame, and a base is fixedly installed at the bottom of the electric lifting frame, the base being a structure for supporting the bottom.

[0014] In a preferred embodiment, a rotating seat is rotatably connected to the top of the base, the rotating seat being a structure for driving the item to rotate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This continuously winding film wrapping machine is supported by a support block and contacts the film roll with a push rod. When the film roll is exhausted, the reset spring resets and drives the limit plate to move, so that the fiberboard adheres to the sensor. The sensor detects and pauses the rotating seat, thus avoiding the film running out and affecting the winding effect, and improving the convenience of the continuously winding film wrapping machine.

[0017] 2. This continuously winding film wrapping machine uses the operation of an electric push rod inside the clamping frame to push the clamping plate to hold the film inside the clamping frame. When the rotating seat stops, the electric push column inside the connecting plate pushes the two heating devices to fit together. The heating devices heat and fuse the two films. The heating temperature of the heating devices is relatively low, ensuring that the films fit together but do not melt. The operation of the electric push rod and electric push column resets the heating devices and releases the clamping of the film, allowing the equipment to continue running. This avoids the problem of the film running out and affecting the winding effect, and also avoids the tediousness of manual replacement. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Combined with appendix Figure 1-4In this embodiment, a continuously winding film winding machine includes: a support plate 1, two rotating disks 11 rotatably connected to the top two sides of the support plate 1, an air shaft 12 rotatably connected to the top of the rotating disks 11, a film roll 13 clamped and connected to the outside of the air shaft 12, a support frame 14 fixedly installed on one side of the support plate 1, the support frame 14 being in the shape of a "C", two rubber rollers 15 rotatably connected to the middle of the inside of the support frame 14, guide rollers 16 rotatably connected to the two sides of the inside of the support frame 14, an electric lifting frame 17 slidably connected to one side of the support frame 14, a base 18 fixedly installed at the bottom of the electric lifting frame 17, and a rotating seat 19 rotatably connected to the top of the base 18.

[0025] Specifically, the operation of the electric lifting frame 17 effectively drives the support frame 14 to move up and down, thereby controlling the support plate 1 so that it can precisely support the two rotating disks 11. After being supported, the rotating disks 11 can smoothly drive the air shaft 12 to rotate. The air shaft 12 is responsible for clamping and supporting the film roll 13, ensuring that the film roll 13 can be wound stably. In addition, the presence of the base 18 provides a solid bottom support for the entire continuously winding film winding machine, ensuring the stability and reliability of the equipment.

[0026] Two support blocks 2 are fixedly installed on both sides of one side of the support plate 1. The support blocks 2 are in the shape of an "L". A sensor 21 is fixedly installed in the middle of one side of the support block 2. A push rod 22 is slidably connected inside the support block 2. A limit plate 23 is fixedly installed on one side of the push rod 22. A reset spring 24 is fixedly installed on one side of the limit plate 23. A pull ring 25 is fixedly installed on the other side of the limit plate 23.

[0027] Specifically, by setting a reset spring 24, the push rod 22 is effectively driven to move inside the support block 2. This movement allows the push rod 22 to fit tightly against the film roll 13, ensuring the correct use of the film. When the film roll 13 gradually approaches the end of its use, the limit plate 23 will fit tightly against the sensor 21. This action will trigger the mechanism of closing the rotating seat 19, thereby stopping the further rotation of the film in time. This design avoids the problem of the winding effect being affected by the film running out, ensuring the smoothness and efficiency of the entire winding process. The sensor 21 uses model D5VA-3B1.

[0028] Two connecting plates 3 are fixedly installed on both sides of the support plate 1. Two electric push columns 31 are fixedly installed on both sides inside the connecting plate 3. A heating device 32 is fixedly installed on one side of the electric push column 31. A clamping frame 33 is fixedly installed in the middle of one side of the heating device 32. The clamping frame 33 is in the shape of a "C". An electric push rod 34 is fixedly installed on one side inside the clamping frame 33. A clamping plate 35 is fixedly installed on one side of the electric push rod 34.

[0029] Specifically, the movement of the electric push rod 34 inside the clamping frame 33 drives the clamping plate 35 to move. This movement is for the effective clamping of the film. The movement of the clamping plate 35 is achieved by the extension and retraction of the electric push rod 34. After receiving a control signal, the electric push rod 34 will extend and retract according to a predetermined program. At the same time, the movement of the electric push columns 31 on both sides inside the connecting plate 3 pushes the two heating devices 32 to fit together. The fitting of the heating devices 32 is for clamping, heating and fusing the two films. This process is achieved by temperature control and pressure control of the heating devices 32 to ensure that the films fuse under appropriate temperature and pressure, thereby achieving the expected processing effect.

[0030] Working principle: First, the push rod 22 inside the support block 2 adheres to one side of the film roll 13. When the film roll 13 is used, its diameter shortens, causing the push rod 22 to move inside the support block 2 via the return spring 24. When the film roll 13 is exhausted, the limit plate 23 touches the sensor 21, thus pausing the rotating seat 19. The operation of the electric push columns 31 on both sides inside the two connecting plates 3 pushes the two heating devices 32 to adhere, performing low-temperature heating and bonding of the two films. The retraction of the electric push rod 34 inside the clamping frame 33 causes the clamping plate 35 to loosen its grip on the film. After the heating device 32 has finished heating, it resets by retracting the electric push column 31, simultaneously opening the rotating seat. 19. This allows for quick replacement of the film roll 13, avoiding the need for manual replacement after use, which leads to cumbersome operation and poor winding effect. This improves the convenience and continuous winding effect of the continuous winding film wrapping machine. After the film roll 13 is replaced, the corresponding air shaft 12 to be replaced is released, and the film roll 13 to be replaced is taken out. The film roll 13 is placed on the outside of the air shaft 12, and the film roll 13 is clamped by the operation of the air shaft 12. The film is pulled out and placed into the corresponding clamping frame 33. The operation of the electric push rod 34 causes the clamping plate 35 to clamp and fix the film, thus improving the convenience of the continuous winding film wrapping machine.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
