Description

Technical Field

[0001] The utility model relates to the field of winding film machine equipment, in particular to a feeding device for a winding film machine. Background Technique

[0002] A winding film machine, also known as a pallet strapping machine, a stretch film winding machine, etc., is a special packaging machine designed to achieve mechanized film winding; it plays an indispensable role in the packaging process of modern enterprises, especially in the packaging process of export-oriented enterprises.

[0003] When the winding film machine is in use, the film on the winding roller is pulled out by the feeding device for winding work. After winding is completed, at this time, due to the large weight and inertia of the winding roller, it will still rotate for a period of time under the action of inertia, so that the film on the winding roller is scattered, which is likely to cause the film to be scattered and even intertwined, affecting the subsequent packing work. Therefore, there is an urgent need for a device to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a feeding device for a winding film machine to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A feeding device for a winding film machine, including an electric slide rail, a fixed frame is installed on one side of the electric slide rail, and the electric slide rail drives the fixed frame to move up and down. A first movable roller is movably embedded on one side of the fixed frame, a second movable roller is movably embedded inside the fixed frame, and a third movable roller is movably embedded inside the fixed frame. When in use, the winding film roller is sleeved outside the third movable roller, and the film is pulled out through the position between the first movable roller and the second movable roller. A first turntable is movably embedded at the bottom end of the fixed frame, a second turntable is fixedly embedded at the lower end of the fixed frame, and a fixing mechanism for conveniently fixing the second turntable is arranged at the lower end of the fixed frame. A control mechanism for controlling the fixing mechanism is arranged inside the first turntable. The fixing mechanism includes an extension block, a movable rod, a first spring, an arc-shaped block and an electromagnet. The extension block is fixed at the lower end position of the fixed frame, the movable rod is movably inserted through the center position of the extension block, the electromagnet is fixedly embedded at the lower end position of the fixed frame, the arc-shaped block is fixed on one side of the movable rod, and the first spring is fixed between the arc-shaped block and the extension block. Before the device finishes packing, at this time, the electromagnet is in the starting state, adsorbing the movable rod and fixing it on the electromagnet. At this time, the first spring is in a compressed state, and the arc-shaped block is away from the second turntable. When the machine stops, at this time, the electromagnet is turned off, and the first spring returns to its original state, so that the arc-shaped block closely adheres to the outside of the second turntable, thereby using the frictional force to make the second turntable drive the third movable roller to stop rotating quickly, preventing the film on the winding roller from scattering too much, and facilitating the subsequent packing work.

[0006] Preferably, the control mechanism includes a groove body, a second spring, a counterweight ball and a control switch. The groove body is formed on the inner side of the first turntable. The second spring is fixed on the inner side wall of the groove body. The counterweight ball is fixed on one side of the second spring. The control switch is inlaid and fixed on the inner side wall of the groove body. When the device is started in use, the film is pulled out, driving the third movable roller to rotate, and the film drives the first movable roller to rotate, causing the first turntable to rotate. The centrifugal force causes the counterweight ball to press the control switch, starting the electromagnet, and the arc-shaped block moves away from the second turntable. At this time, the film discharging starts to be smooth. When it is closed, at this time, the first movable roller has a small mass and small inertia, and the first movable roller stops quickly. In this way, the counterweight ball moves away from the control switch, the electromagnet is turned off, and the arc-shaped block presses the second turntable, causing the second turntable to stop.

[0007] Preferably, the first turntable is coaxially installed with the bottom end of the first movable roller.

[0008] Preferably, the movable rod is made of magnetic metal material.

[0009] Preferably, the first spring is sleeved outside the movable rod.

[0010] Preferably, the control switch is electrically connected to the electromagnet through a slip ring.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] Before the device of the present utility model finishes packing, at this time, the electromagnet is in the starting state, adsorbing the movable rod and fixing it on the electromagnet. At this time, the first spring is in a compressed state, and the arc-shaped block moves away from the second turntable. When the machine stops, at this time, the electromagnet is turned off, and the first spring resets, causing the arc-shaped block to closely adhere to the outside of the second turntable, thereby using the frictional force to cause the second turntable to drive the third movable roller to quickly stop rotating, preventing too much film on the winding roller from scattering, and facilitating the subsequent packing work.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-4 , the present invention provides a feeding device for a winding film machine, including an electric slide rail 1. A fixed frame 2 is installed on one side of the electric slide rail 1. The electric slide rail 1 drives the fixed frame 2 to move up and down. A first movable roller 3 is movably embedded on one side of the fixed frame 2. A second movable roller 4 is movably embedded inside the fixed frame 2. A third movable roller 5 is movably embedded inside the fixed frame 2. When in use, the winding film roll is sleeved outside the third movable roller 5, and the film is pulled out through the position between the first movable roller 3 and the second movable roller 4. A first turntable 6 is movably embedded at the bottom end of the fixed frame 2. The first turntable 6 is coaxially installed with the bottom end of the first movable roller 3. A second turntable 11 is fixedly embedded at the lower end of the fixed frame 2. There is a fixing mechanism at the lower end of the fixed frame 2 for conveniently fixing the second turntable 11. There is a control mechanism for controlling the fixing mechanism inside the first turntable 6. The fixing mechanism includes an extension block 12, a movable rod 14, a first spring 16, an arc-shaped block 15 and an electromagnet 13. The extension block 12 is welded and fixed at the lower end position of the fixed frame 2. The movable rod 14 is movably inserted through the center of the extension block 12. The movable rod 14 is made of magnetic metal material. The electromagnet 13 is fixedly embedded at the lower end position of the fixed frame 2. The arc-shaped block 15 is welded and fixed on one side of the movable rod 14. The first spring 16 is welded and fixed between the arc-shaped block 15 and the extension block 12. Before the device finishes packing, at this time, the electromagnet 13 is in the starting state, adsorbing the movable rod 14 and fixing it on the electromagnet 13. At this time, the first spring 16 is in a compressed state, and the arc-shaped block 15 is far away from the second turntable 11. When the machine stops, at this time, the electromagnet 13 is turned off, and the first spring 16 returns to its original state, so that the arc-shaped block 15 tightly adheres to the outside of the second turntable 11, thereby using the friction force to make the second turntable 11 drive the third movable roller 5 to quickly stop rotating, preventing too much film on the winding roller from scattering, and facilitating the subsequent packing work.

[0020] The control mechanism includes a trough body 7, a second spring 8, a counterweight ball 10, and a control switch 9. The trough body 7 is provided inside the first turntable 6. The second spring 8 is welded and fixed to the inner side wall of the trough body 7. The counterweight ball 10 is welded and fixed to one side of the second spring 8. The control switch 9 is inlaid and fixed to the inner side wall of the trough body 7. The control switch 9 is electrically connected to the electromagnet 13. When in use, the device is started, so that the film is pulled out, driving the third movable roller 5 to rotate, and the film drives the first movable roller 3 to rotate, causing the first turntable 6 to rotate. The centrifugal force causes the counterweight ball 10 to press the control switch 9, starting the electromagnet 13. The arc-shaped block 15 moves away from the second turntable 11. At this time, the film discharging starts to be smooth. When shutting down, at this time, the first movable roller 3 has a small mass and a small inertia, and the first movable roller 3 quickly stops. In this way, the counterweight ball 10 moves away from the control switch 9, the electromagnet 13 is turned off, and the arc-shaped block 15 presses the second turntable 11, causing the second turntable 11 to stop.

[0021] Working principle: Before the device finishes packing, at this time, the electromagnet 13 is in the starting state, adsorbing the movable rod 14 fixed on the electromagnet 13. At this time, the first spring 16 is in a compressed state, and the arc-shaped block 15 moves away from the second turntable 11. When shutting down, at this time, the electromagnet 13 is turned off, and the first spring 16 returns to its original state, causing the arc-shaped block 15 to closely adhere to the outer side of the second turntable 11, thereby using the frictional force to cause the second turntable 11 to drive the third movable roller 5 to quickly stop rotating, preventing too much film on the winding roller from spreading out, and facilitating the subsequent packing work.
