DETAILED DESCRIPTION

[0023] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0024] Please refer to Figure 1-8 A semi-automatic film strapping machine comprises a lower box body 1 and a groove hole 12 is provided on the surface of the lower box body 1, a vertical plate 2 is provided in the lower box body 1, the vertical plate 2 extends upward in the groove hole 12, a rotatable ring gear 4 is provided on one side of the vertical plate 2, the ring gear 4 has a notch, and the overall shape is C-shaped, a film loading wheel 5 is provided on the ring gear 4, a film roll is provided on the film loading wheel 5, a film 51 on the film loading wheel 5 extends outward in the groove hole 12, a driving mechanism is provided in the lower box body 1, and the driving mechanism drives the ring gear 4 to rotate so that the film 51 is wound onto the workpiece.

[0025] When in use, the workpiece to be bundled is supported by hands and placed above the slot 12 at the notch of the ring gear 4. Then the end of the film 51 is first glued to the workpiece, and then the driving mechanism is started. After the driving mechanism is running, it drives the ring gear 4 to rotate. When the ring gear 4 rotates, the film wheel 5 and the film roll rotate accordingly, so that the film 51 is wound around the surface of the workpiece layer by layer. After the film bundling is completed, the film can be cut off. Such use can greatly reduce the labor intensity of manual labor, improve the efficiency of film bundling, and has strong practicality.

[0026] Specifically, the outer circumference of the ring gear 4 is provided with multiple outer limiting wheels 41, and the inner circumference of the ring gear 4 is provided with multiple inner limiting wheels 42, and the ring gear 4 rotates between the outer limiting wheels 41 and the inner limiting wheels 42; that is, the inside and outside of the ring gear 4 are limited by the outer limiting wheels 41 and the inner limiting wheels 42, thereby avoiding the deviation of the ring gear 4 and ensuring stable rotation.

[0027] In this embodiment, the driving mechanism includes a stepper motor 13, a synchronous pulley 15, a synchronous belt 14 and two transmission gears 43. The two transmission gears 43 are symmetrically arranged on both sides below the ring gear 4 and meshed with the ring gear 4. The stepper motor 13 and the synchronous pulley 15 are arranged on the other side of the vertical plate 2. The stepper motor 13 is connected to one of the transmission gears 43, and the synchronous pulley 15 is connected to the other transmission gear 43. The stepper motor 13 and the synchronous pulley 15 are connected to each other through the synchronous belt 14.

[0028] Since the transmission gear 43 is meshed with the ring gear 4, when the stepper motor 13 is running, the synchronous pulley 15 rotates accordingly, and at the same time can drive the transmission gear 43 on the outside of the vertical plate to rotate. After the transmission gear 43 rotates, the ring gear 4 rotates accordingly, so that when the ring gear 4 rotates, the film wheel 5 and the film roll rotate accordingly, thereby winding the film 51 layer by layer onto the surface of the workpiece.

[0029] The lower box body 1 is also provided with an upper cover body 3, which covers the vertical plate 2. After covering, the ring gear 4, the outer limit wheel 41 and the inner limit wheel 42 on the vertical plate 2 are shielded, thereby avoiding damage caused by collision with foreign objects and preventing safety hazards.

[0030] In use, in order to prevent the film loading wheel from deviating, a gasket 52 is provided on the outside of the film loading wheel 5, and an adjusting screw 54 is provided on the outside of the gasket 52. The adjusting screw 54 is coaxially arranged with the film loading wheel 5, and a spring 53 is provided between the gasket 52 and the adjusting screw 54. The spring 53 pushes the gasket 52 to contact the film roll on the film loading wheel 5. After the film roll is sleeved on the film loading wheel 5, the gasket 52 is sleeved on the outside, and then the adjusting screw 54 and the spring 53 are installed. The spring is compressed, and its elastic force will push the gasket 52, so that the gasket contacts the film roll to prevent its deviation, and make the film tight when bundling.

[0031] As a preferred solution, lifting handles 11 are provided on both sides of the lower box body 1 to facilitate the overall movement and lifting of the equipment. The ends of the slots 12 are provided with cutting teeth 16, and the film is cut by the cutting teeth 16 after being bundled, which is highly practical.

[0032] Please refer to the usage status of this semi-automatic film strapping machine Fig. 9 When in use, the workpiece is manually supported and placed in the ring gear 4. After one end of the film is adhered to the workpiece, the stepper motor 13 is started. After the ring gear 4 rotates, the film loading wheel 5 starts to rotate accordingly, thereby bundling the film on the workpiece.

[0033] In this embodiment, before or after use, the notch of the ring gear 4 is always facing outward, so that a workpiece can be placed in the ring gear 4 .

[0034] Based on the above embodiment, a magnetic signal sensor or a turn counter may be further provided on the back of the ring gear 4, and a signal is given to the sensor or the turn counter by the magnet, so as to determine the number of turns and the stop position.

[0035] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
