DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Embodiment

[0021] Referring to Figures 1 - 3 , a bubble film deviation rectifying device for a bubble bag making machine, which includes a positioning bracket 1. Mounting frames 15 are fixedly arranged at the tops on both sides of the positioning bracket 1. A guiding roller 2 for driving the bubble film is rotatably installed in the positioning bracket 1. Two groups of transverse through grooves 7 are symmetrically formed in the positioning bracket 1 in the front-back direction. An auxiliary component is arranged on the positioning bracket 1 and the guiding roller 2. The auxiliary component includes U-shaped limit frames 3 symmetrically sliding in the left-right direction on the guiding roller 2. A U-shaped rubber pad 4 is arranged in the inner cavity of the U-shaped limit frame 3. The inner cavity of the U-shaped rubber pad 4 fits on the guiding roller 2. By arranging the U-shaped rubber pad 4, it is avoided that the U-shaped limit frame 3 directly contacts the surface of the guiding roller 2 and wears its surface, so as to effectively avoid damage to the bubble film caused by the unevenness generated by wear. A support plate 8 is fixed on each group of U-shaped limit frames 3, and the top of the support plate 8 penetrates through the transverse through groove 7 and extends upward. Extension plates 5 are fixedly arranged at the bottoms on both the front and back sides of the positioning bracket 1. A T-shaped rod 6 is horizontally inserted on each group of extension plates 5, and one end of the T-shaped rod 6 is fixed on the U-shaped limit frame 3. The design of the extension plate 5 and the T-shaped rod 6 improves the stability of the U-shaped limit frame 3 during movement and avoids blockage. Vertical shafts 10 are rotatably installed on both sides of the top of the positioning bracket 1. A synchronous pulley 11 is fixed on each group of vertical shafts 10. A motor 13 is fixedly arranged on the right side of the top of the positioning bracket 1 through an auxiliary frame, and the output shaft of the motor 13 is fixed on one of the vertical shafts 10. A synchronous belt 12 is drivingly connected on the synchronous pulley 11, and the support plate 8 is fixed on the synchronous belt 12. The two groups of support plates 8 are arranged in a front-back staggered manner. The two groups of support plates 8 arranged in a front-back staggered manner enable the two groups of support plates 8 to move in the reverse direction during transmission. By arranging the auxiliary component, the two groups of U-shaped limit frames 3 can be driven to synchronously displace in the reverse direction on the guiding roller 2, which is convenient for the user to quickly limit the bubble film according to the size of the bubble film, effectively avoiding the deviation of the bubble film during transmission and improving the overall deviation rectifying effect of the device. A limit seat 14 inserted and used with the synchronous belt 12 is fixedly arranged at the center of the top of the positioning bracket 1. The design of the limit seat 14 can limit the synchronous belt 12 and improve the stability of the synchronous belt 12 during transmission, avoiding excessive jitter due to the overlong synchronous belt 12. A controller is arranged on the right side of the positioning bracket 1. A positioning rod 9 is horizontally inserted on the top of each group of support plates 8, and both ends of the positioning rod 9 are fixed on both sides of the inner cavity of the transverse through groove 7. The design of the positioning rod 9 improves the stability of the support plate 8 during movement.

[0022] In the present utility model, the user turns on the motor 13 through the controller. At this time, the motor 13 drives one set of vertical shafts 10 to rotate. Thus, with the cooperation of two synchronous pulleys 11, the synchronous belt 12 can be driven to transmit. At this time, the synchronous belt 12 and the support plate 8 can form a complete closed-loop structure, and the support plates 8 are arranged staggeredly. Therefore, when the synchronous belt 12 is transmitting, the two support plates 8 can move inwards synchronously, and then can drive the two U-shaped limit frames 3 to move inwards synchronously on the guide rollers 2 until the U-shaped limit frames 3 are attached to the bubble film. Thus, when the bubble film is transmitting, the bubble film can be positioned, effectively avoiding the offset of the bubble film during transmission and improving the overall deviation correction effect of the device.

[0023] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present utility model.
