Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to a single-row strip bag packaging machine. Background Art

[0002] Granule packaging machine is a general term for equipment used to package powder items. According to the packaging type, it is divided into: three-side sealing granule packaging machine, four-side sealing granule packaging machine, back-sealing granule packaging machine, and strip bag packaging machine is a type of back-sealing granule packaging machine. As the name suggests, strip bag packaging is the packaging of material particles into long strip-shaped disposable packaging bags for easy storage and retrieval. The packaging process in the strip bag packaging machine is as follows: the film-like packaging material is transported from top to bottom under the traction of the traction and shearing device at the bottom end of the packaging machine; the two sides of the film are rolled inward into a cylindrical packaging strip through the synthetic hole on the former, and a certain amount of material particles are injected into it; the packaging strip runs downward, and when it reaches the longitudinal seal back seal section, the longitudinal seal back seal section body clamps the two side films on the back of the packaging strip longitudinally, and hot-presses and seals them to complete the longitudinal seal; the traction and shearing device continues to pull the packaging strip downward, separates from the longitudinal seal back seal section, and enters the bottom seal section. The bottom seal section body clamps the packaging strip horizontally, and hot-presses and seals it to complete the bottom seal. Finally, the traction and shearing device pulls the packaging strip that has completed the longitudinal and bottom seals to the discharge port, and cuts it horizontally along the bottom seal opening into independent long strip packaging strips, thus completing the strip bag packaging.

[0003] Chinese patent publication number CN204956982U discloses a strip bag packaging machine comprising a machine body, on which are arranged, from top to bottom, a former, a longitudinal back seal section, a bottom seal section, and a traction and shearing device, forming a strip bag running track. The former is provided with a long strip positioning block at the bottom, which is horizontally fixed to the machine body and rests on the bottom surface of the former. A side retaining plate is provided between the longitudinal back seal section and the bottom seal section, with one end of the side retaining plate connected to the machine body and the other end extending into the strip bag running track. The advantages of this utility model are: the horizontal positioning block is designed to effectively improve the horizontal stability of the former; the side retaining plate is designed to press the longitudinal seal against the surface of the packaging strip during the downward pulling of the packaging strip, avoiding problems such as irregular hot pressing and insufficient hot pressing effect during the bottom sealing process, thereby ensuring the quality stability and aesthetics of the strip bag packaging.

[0004] However, the above-mentioned disclosed solution has the following shortcomings: the above-mentioned device achieves the edge sealing effect by squeezing when in use, but in actual use, the transmission effect of the above-mentioned device on the strip packaging bag is inaccurate, resulting in inconsistent length of the final packaging bag.

[0029] The following is combined with Figure 1-6 The utility model is described in further detail.

[0030] Example 1

[0031] like Figures 1-6 As shown, in order to solve the existing problems, in this embodiment, the utility model discloses a single-row strip bag packaging machine, including a mounting plate 1 and a raw material roller 2 rotatably connected to its side, the mounting plate 1 side is connected to a tensioning roller assembly 3, the mounting plate 1 side is rotatably connected to a guide roller 4, the mounting plate 1 side is connected to a lifting component 5, and the lifting component 5 is connected to a heat sealing component 6.

[0032] The tensioning roller assembly 3 includes a tensioning roller and an elastic telescopic rod. The side of the elastic telescopic rod is connected to the side of the mounting plate 1. The telescopic end of the elastic telescopic rod is connected to a rotating bracket, and the rotating bracket is rotatably connected to the tensioning roller.

[0033] The lifting component 5 includes a lifting rod 504 connected to the mounting plate 1, the lifting rod 504 is slidably connected to a threaded member 503, the threaded member 503 is threadedly connected to a threaded rod 502, one end of the threaded rod 502 is connected to a coupling 501, and the other end of the coupling 501 is connected to a power device.

[0034] The heat sealing component 6 includes a fixed bracket 601 connected to the side of the threaded member 503, the side of the fixed bracket 601 is connected to an electric telescopic rod 602, the telescopic end of the electric telescopic rod 602 is connected to a sliding bracket 603, and both ends of the sliding bracket 603 are connected to sliding rods 604. The side of the threaded member 503 is connected to a shaft sleeve 605, and the inner wall of the shaft sleeve 605 is slidably connected to the sliding rod 604.

[0035] The specific working principle is: this device can effectively improve the accurate transmission effect of the belt-loaded packaging bags. Compared with traditional devices, this device can ensure that the length of each processed packaged packaging bag is the same, thereby ensuring the production consistency of this device.

[0036] When this device is in use, the raw material roller 2 structure can store the strip packaging bag raw material. When in use, the lifting component 5 drives the heat sealing component 6 to rise, thereby clamping and heating the packaging bag. When the packaging bag is discharged, it passes through the tensioning roller assembly 3 and the guide roller 4 to ensure that the packaging bag is discharged at an accurate position. At the same time, the structure of the tensioning roller can ensure that the packaging bag is always in a tensioned state.

[0037] The power device can drive the threaded rod 502 to rotate via the coupling 501, and the rotation of the threaded rod 502 drives the threaded member 503 to rise, fall and slide. The threaded member 503 can be limited by the lifting rod 504, thereby preventing the threaded member 503 from tilting.

[0038] The screw member 503 drives the heat sealing component 6 to rise and slide. When the screw member 503 moves to the top, the electric telescopic rod 602 extends outward, thereby driving the clamping bracket 609 to slide through the sliding bracket 603 and the sliding rod 604, thereby making the sliding heating element 610 close to the heating element 608. At this time, the heating element contacts the packaging bag to achieve a heat-sealing effect. At the same time, the heating element clamps the packaging bag. At this time, the screw rod 502 rotates in the opposite direction, and through the clamping effect of the heating element, the packaging bag is pulled downward to be discharged. When the screw member 503 moves to the bottom of the screw rod 502, the electric telescopic rod 602 contracts inward, thereby separating the heating element, thereby achieving the heat-sealing effect of the device and preventing the packaging bag from returning. When the heating element is in the separated state, the screw member 503 rises again driven by the screw rod 502, thereby repeating the heat-sealing effect of the device. The combination of the screw rod 502 and the screw member 503 can ensure that the same length of the packaging bag is lowered each time.

The side of the threaded member 503 away from the sleeve 605 is connected to the hollow connecting member 606, and the other end of the hollow connecting member 606 is connected to the abutting bracket 607, and the side of the abutting bracket 607 is connected to the abutting heating member 608, and the abutting heating member 608 and the sliding heating member 610 are arranged opposite to each other, and the sliding rod 604 is slidably connected to the inner wall of the hollow connecting member 606.

[0041] The bottom of the supporting bracket 607 is connected to a splint 611, the bottom of the clamping bracket 609 is connected to a splint 611, the bottom of the splint 611 is connected to an air outlet pipe 613, the outer arc surface of the air outlet pipe 613 is provided with a plurality of air outlet holes distributed at equal intervals, and one end of the side of the air outlet pipe 613 is connected to an air pressure connector 612.

[0042] The specific working principle is: through the combined structure of the air outlet pipe 613 and the air pressure joint 612, the packaging bag after the heat plastic sealing process can be air-cooled when the device is used, thereby avoiding problems such as deformation of the heated packaging bag.

[0043] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
