Description

Technical Field

[0001] The utility model relates to the technical field of film bag production devices, in particular to a film bag transmission floating deviation correcting device. Background Art

[0002] Plastic packaging bags are packaging bags made of plastic as raw materials and used to produce various daily necessities. They are widely used in daily life and industrial production. Commonly used plastic packaging bags are mostly made of polyethylene film, which is non-toxic and can be used to hold food. Before forming, the plastic packaging bag is a strip-shaped plastic film, which is a double-layer plastic film. The plastic film is cut into equal lengths by a cutting device, and one end of the cut plastic film is glued to obtain a plastic packaging bag. When the plastic film is produced, it is conveyed by a conveyor roller. Since the conveyor line is relatively long, it is easy to deviate during the conveying process. The patent with publication number CN207890759U discloses a plastic film deviation correction device, including a base and a driving mechanism, a winding roller is rotatably connected to the upper end of the winding frame, and a winding roller is rotatably connected to the upper end of the unwinding frame. A conveying frame is provided between the winding frame and the unwinding frame, and a conveying roller is rotatably connected to the upper end of the conveying frame. It also includes a screw, a slider, a deviation correction frame, a deviation correction part, a controller, an infrared transmitter, and an infrared receiver that can receive the signal transmitted by the infrared transmitter. The device can prevent the plastic film from deviating during the conveying process. However, the infrared transmitter used for detection and the infrared receiver capable of receiving the signal transmitted by the infrared transmitter are fixed on the base, which makes it impossible to correct the deviation of plastic films of different widths and has a narrow applicability.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the technical solutions in the present invention are further described below in conjunction with the accompanying drawings and embodiments.

[0023] See also Figures 1 to 4The cam 32 is a vertically-spaced roller 36 which is arranged on the upper and lower sides of the roll 31 and the lower and lower sides of the roll 32 are respectively connected to each other via the cam 32 and the roll 32 is provided with a plurality of cylinders 4. The cam 32 is a vertically-spaced roller 36 which is arranged on the lower and upper sides of the roll 32. A first conveying roller 31 is arranged between the two support plates 1 to play the role of tensioning the film bag; a horizontal column 5 is fixedly arranged between the two support plates 1, and the horizontal column 5 is arranged perpendicular to the conveying direction. A movable sleeve 51 is slidably sleeved on the horizontal column 5 along the length direction of the horizontal column 5, and a control component for controlling the movement of the movable sleeve 51 is provided on the horizontal column 5, and the movement of the movable sleeve 51 can be controlled by the control component. A fixed rod 511 is fixedly arranged on one side of the movable sleeve 51, and a detection photoelectric sensor is fixedly arranged at the lower end of the fixed rod 511, and the photoelectric sensor is used to detect whether the edge of the film bag is located on the normal conveying trajectory; when the edge of the film bag is not detected between the photoelectric sensors, the cylinder 4 is used to control the horizontal movement of the first conveying roller 31 and the horizontal roller 32, so as to control the movement of the film bag and micro-control the position of the film bag so that the film bag maintains the corresponding conveying accuracy, and the control component controls the movement of the photoelectric sensor, which can adapt to the detection of film bags of different widths and has wide adaptability.

[0024] like Figure 3 and Figure 4As shown, the specific structure of the control component is shown, and the control component includes a vertical rod 61 and a pressure block 62. A cavity is provided in the horizontal column 5, and the top of the cavity is open, and the opening is arranged along the length direction of the horizontal column 5. The pressure block 62 is fixed at the upper end of the vertical rod 61, and the lower end of the vertical rod 61 is elastically arranged in the cavity, and the vertical rod 61 is vertically slidably arranged on the movable sleeve 51, which causes the movable sleeve 51 to move when moving on the horizontal column 5. Positioning blocks 611 are fixed on both sides of the vertical rod 61, and positioning rods 612 are arranged on the positioning blocks 611. A plurality of first positioning grooves 501 matching the positioning rods 612 are arranged at intervals on the top of the cavity and along the length direction of the horizontal column 5. Under normal conditions, the positioning rod 612 is located in the first positioning groove 501, thereby limiting the movement of the vertical rod 61, and further limiting the movement of the movable sleeve 51, fixing the movable sleeve 51; when the movable sleeve 51 needs to be moved, the pressing block 62 is pressed downward, and the pressing block 62 drives the vertical rod 61 to move downward, thereby disengaging the positioning rod 612 from the first positioning groove 501, and then the movable sleeve 51 can be moved.

[0025] Furthermore, if Figure 3 and Figure 4 As shown, the bottom of the cavity is provided with a second positioning groove 502, and a connecting column 7 is slidably provided in the second positioning groove 502 along the length direction of the horizontal column 5. A sliding rod 613 is fixed at the bottom of the vertical rod 61, and the sliding rod 613 is vertically slidably connected in the connecting column 7. A first spring 63 is provided on the outer sleeve of the sliding rod 613, and the first spring 63 is located between the connecting column 7 and the vertical rod 61. The connecting column 7 can improve stability. Under normal conditions, the elastic force of the first spring 63 causes the vertical rod 61 to move upward, so that the positioning rod 612 extends into the first positioning groove 501 for limiting. When the movable sleeve 51 is moved, the pressing block 62 is pressed downward, and the vertical rod 61 drives the sliding rod 613 to move downward. The sliding rod 613 slides downward in the connecting column 7, and the first spring 63 is compressed at this time.

[0026] In order to ensure that the positioning rod 612 can extend into the first positioning groove 501, as shown in FIG. Figure 3 and Figure 4 As shown, a second spring 64 is further provided, and the two ends of the second spring 64 are respectively fixedly connected to the pressing block 62 and the movable sleeve 51. Under normal conditions, the elastic force of the second spring 64 causes the pressing block 62 to move upward, thereby causing the vertical rod 61 to drive the positioning rod 612 to move upward.

[0027] Specifically, in order to ensure that the vertical rod 61 and the movable sleeve 51 can smoothly move relative to each other, as shown in FIG. Figure 4 As shown, a through hole 614 is vertically provided on the vertical rod 61 , and the movable sleeve 51 is disposed through the through hole 614 .

[0028] Furthermore, if Figure 1As shown, two second conveying rollers 33 are also provided, wherein one second conveying roller 33 is located directly above the other second conveying roller 33, and the film bag passes between the two second conveying rollers 33, and both conveying rollers 33 are in contact with the film bag, so that the conveyor belt remains flat for subsequent conveying and processing.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
