Description

Technical Field

[0001] This utility model relates to the field of packaging bag opening technology, and in particular to a plastic packaging bag opening device. Background Technology

[0002] Plastic packaging bags are made from plastic and are used to package various daily necessities. They are widely used in daily life and industrial production, but this convenience brings long-term harm. Most commonly used plastic packaging bags are made of polyethylene film, which is non-toxic and therefore suitable for food packaging.

[0003] Traditional packaging bags lack an opening device for the conveyor belt during production. This can lead to adhesion at the cut surface when the raw material is cut, reducing production efficiency. To address this issue, we have developed a plastic packaging bag opening device. Utility Model Content

The opening assembly includes a support plate, which is disposed on the top of the support frame. A flaring column is fixedly connected to the top of the support plate. Connecting blocks are symmetrically fixedly connected to the top of the flaring column. Flaring legs are symmetrically fixedly connected to the tops of both connecting blocks. The flaring legs are inclined and have a certain degree of resilience.

[0007] By incorporating an opening component, the opening of the plastic bag can be stretched open to prevent sticking and improve the overall quality of the product.

A second pulley is fixedly connected to the end of the conveying roller away from the motor. A first pulley is fixedly connected to the outer side of one of the two clamping rollers, and the first pulley and the second pulley are connected by a belt drive.

[0009] The designed conveying components prevent the cut ends of the packaging bag materials from sticking together during the hot melt cutting process, thereby improving the production efficiency of packaging bags, reducing the probability of defective products, and featuring a simple structure and strong practicality.

[0010] In a preferred embodiment, a rotating roller is rotatably connected to the top side of the support frame, and the rotating roller is used in conjunction with the conveying roller.

[0011] The rotating rollers can be used to transport the raw material belt, making the transport process smoother.

[0013] The motor can be protected by the protective cover, and the motor can be cooled by the heat dissipation slots.

[0014] In a preferred embodiment, a flat plate is symmetrically fixedly connected between the two fixed plates.

The conveying assembly includes a conveying roller 31, which is rotatably connected to the top of the support frame 1. A motor 32 is fixedly connected to the outer side of one of the two fixed plates 2. The output end of the motor 32 is fixedly connected to the conveying roller 31. Clamping rollers 33 are symmetrically rotatably connected between the two fixed plates 2. A gear 36 is fixedly connected to one end of each clamping roller 33. The two gears 36 are meshed together. A second pulley 35 is fixedly connected to the end of the conveying roller 31 away from the motor 32. A first pulley 34 is fixedly connected to the outer side of one of the two clamping rollers 33. The first pulley 34 and the second pulley 35 are connected by belt drive. The flared support leg is inclined and has a certain degree of resilience.

[0030] In this embodiment: two clamping rollers 33 are fitted onto the outside of the support plate 37. Then, the motor 32 is started, and the output end of the motor 32 rotates, driving the conveyor roller 31 to rotate. The rotation of the conveyor roller 31 drives the second pulley 35 to rotate, and the first pulley 34 drives one of the clamping rollers 33 to rotate.

[0031] In the above technical solution, considering the problem that adhesion may easily occur at the cut surface when the packaging bag raw material is cut, the specific operation is as follows to solve this problem:

A controller 8 is fixedly connected to the outside of one of the two fixed plates 2, and the motor 32 is electrically connected to the controller 8.

[0033] In this embodiment: the rotating roller 4 can transport the raw material belt, making the transport process smoother; the protective cover 6 can protect the motor 32; the heat dissipation groove 7 can dissipate heat from the motor 32; the smoothing plate 5 can smooth the packaging bag to avoid wrinkles during cutting; and the controller 8 allows the operator to easily control the motor 32 to turn on and off, making operation simpler.

[0034] Working principle: In actual use, the operator passes one end of the packaging bag raw material roll through the conveyor roller 31, and then places it between the two clamping rollers 33 on the outside of the support plate 37. Then, the motor 32 is started. The output end of the motor 32 rotates, which drives the conveyor roller 31 to rotate. The rotation of the conveyor roller 31 drives the second pulley 35 to rotate. The first pulley 34 drives one of the clamping rollers 33 to rotate. The two gears 36 rotate, which drives the two clamping rollers 33 to rotate, thus starting to convey the packaging bag raw material roll. The packaging bag raw material is placed on the outside of the flared support leg 310. The flared support leg 310 supports the packaging bag, which can prevent the cut ends of the packaging bag raw material from sticking together during hot melt cutting.
