Description

Technical Field:

[0001] The utility model belongs to the technical field of straw packaging machines, and particularly refers to a paper film folding and guiding assembly of a straw packaging machine. Background Art:

[0002] The single-straw packaging equipment disclosed in the existing Chinese utility model patent (authorization announcement number CN217295021U) includes a machine frame. A straw feeding device, a straw pushing device, a paper film unwinding device, a paper film printing device, a paper film folding device, and a paper film sealing and cutting device are provided on the machine frame. The paper film unwound by the paper film unwinding device sequentially passes through the paper film printing device, the paper film folding device, and the paper film sealing and cutting device. The straw pushing device is connected below the straw feeding device and pushes the straw into the folded paper film. The paper film printing device includes a mounting plate, and two or more printing components are arranged on the mounting plate along the paper film conveying direction. Each printing component includes a rubber wheel, a printing roller, and an ink roller. The rubber wheel can elastically swing and press the upper part of the printing roller, the ink roller is in contact with the lower part of the printing roller, the ink roller is provided with an ink cartridge, the printing roller is provided with a servo motor, and the printing roller and the ink roller are linked. Among them, the paper film folding device includes a folding block, a folding groove is provided on the folding block, a guiding block is provided above the folding groove, and the guiding block is fixed on the bracket.

[0003] Although the paper film can be folded from the flat state through the folding groove, since the width of the groove of the folding block is smaller than the width of the flat paper film, in the actual production process, the contact between the paper film and the folding block is not easy enough and the paper film is prone to deviation, resulting in the paper film disengaging from the folding groove and unable to achieve the folding purpose. Summary of the Invention:

[0004] The purpose of the utility model is to provide a paper film folding and guiding assembly of a straw packaging machine, which effectively increases the width by means of a widened guiding part, so that the paper film can stably enter the folding groove through the widened guiding part.

[0005] The utility model is realized as follows:

[0006] A paper film folding and guiding assembly of a straw packaging machine includes a folding block arranged on a machine frame. A folding through groove for the axial passing of the paper film and the straw is opened on the folding block. Widened guiding parts are arranged on the folding block on the left and right sides of the feeding port of the folding through groove, and the total width formed between the two widened guiding parts is greater than or equal to the width of the flat paper film.

[0007] In the above-mentioned paper film folding and guiding assembly of a straw packaging machine, the widened guiding part and the folding block are of an integral structure, and the widened guiding part extends outward from the corresponding side wall of the folding block.

[0008] In the paper film folding guide assembly of the above-mentioned straw packaging machine, a guide shaft rod is arranged along the width direction of the folding through groove on the folding block.

[0009] The guide shaft rod penetrates and is fixed on the folding block, and both ends thereof extend out of the folding block respectively to form the widened guide part.

[0010] Or there are two guide shaft rods. One end of the guide shaft rod is embedded on the folding block, and the other end forms the widened guide part.

[0011] In the paper film folding guide assembly of the above-mentioned straw packaging machine, the width of the folding through groove gradually becomes narrower from the feeding end to the discharging end.

[0012] In the paper film folding guide assembly of the above-mentioned straw packaging machine, the bottom surface of the folding through groove is a horizontal plane, and the depth of the folding through groove gradually increases from the feeding end to the discharging end.

[0013] The prominent advantages of the present utility model compared with the prior art are:

[0014] The structure of the present utility model is simple, the design is reasonable and the cost is low. By means of the widened guide part, the width is effectively increased, the contact area between the folding block and the paper film is increased, and thus the paper film can stably enter the folding groove through the widened guide part. Description of the drawings:

[0015] Figure 1 is the structural diagram of the folding block of the present utility model assembled on the frame;

[0016] Figure 2 is the structural diagram of the folding block of the present utility model.

[0017] In the figure: 1, frame; 2, folding block; 3, paper film; 4, folding through groove; 5, widened guide part. Specific embodiments:

[0018] The following further describes the present utility model with specific embodiments. Refer to Figure 1 —2:

[0019] A paper film folding guide assembly of a straw packaging machine includes a folding block 2 arranged on a frame 1. A folding through groove 4 for the axial passage of a paper film 3 and a straw is formed on the folding block 2. Widened guide parts 5 are arranged on both the left and right sides of the feeding port of the folding through groove 4. The total width formed between the two widened guide parts 5 is greater than or equal to the width of the paper film 3 in a flat state.

[0020] The utility model has a simple structure, reasonable design and low cost. By means of the widened guiding part 5, the width is effectively increased, and the contact area between the folding block 2 and the paper film 3 is increased. Furthermore, the paper film 3 can stably enter the folding groove through the widened guiding part 5.

[0021] Wherein, the widened guiding part 5 can be integrally cast with the folding block 2. The widened guiding part 5 and the folding block 2 are of an integral structure, and the widened guiding part 5 extends outward from the corresponding side wall of the folding block 2.

[0022] In this embodiment, in order to modify and optimize the existing folding block 2, a guiding shaft rod is arranged on the folding block 2 along the width direction of the folding through groove 4. The guiding shaft rod is fixedly penetrated on the folding block 2, and both ends thereof extend outward beyond the folding block 2 respectively to form the widened guiding part 5.

[0023] Certainly, the guiding shaft rods forming the two widened guiding parts 5 can also adopt a split structure: there are two guiding shaft rods. One end of each guiding shaft rod is embedded in the folding block 2, and the other end forms the widened guiding part 5.

[0024] Meanwhile, in order to facilitate the paper film 3 to enter the folding groove, the width of the folding through groove 4 gradually becomes narrower from the feeding end to the discharging end. Correspondingly, in order to facilitate the paper film 3 to form a folded state from the flat state through the folding groove, the bottom surface of the folding through groove 4 is a horizontal plane, and the depth of the folding through groove 4 gradually increases from the feeding end to the discharging end.

[0025] The above embodiments are only one of the preferred embodiments of the utility model, and do not limit the implementation scope of the utility model. Therefore, all equivalent changes made according to the shape, structure and principle of the utility model shall be covered within the protection scope of the utility model.
