[0029] Schematic diagram of a collection device for tearing strips of packaging bags,

[0030] refer to Figures 1 to 4 According to a preferred embodiment of the utility model, a packaging bag tear strip collection device is used to collect tear strips on packaging bags. The packaging bag tear strip collection device includes a shell 10, a collection component 20 and a negative pressure component 30.

[0031] Specifically, Figure 2 As shown, the housing 10 has a containing cavity 101 and an input port 102 , and the input port 102 is located at the top of the housing 10 .

[0032] In addition, the collecting assembly 20 is disposed in the accommodating cavity 101 , and the collecting assembly 20 has a guiding channel 2011 and a collecting chamber 2021 , and both ends of the guiding channel 2011 are respectively connected to the input port 102 and the collecting chamber 2021 .

[0033] In addition, if Figure 2 and Figure 3 As shown, the negative pressure component 30 includes a solenoid valve 301, an air inlet pipe 302 and an exhaust pipe 303. The solenoid valve 301 is fixedly mounted on the shell 10, and the air inlet pipe 302 extends into the guide channel 2011 at one end close to the inlet 102. The exhaust pipe 303 passes through the shell 10 and is connected to the outside.

[0034] It should be noted that, after the operator tears off the tear strip on the packaging bag, he only needs to move the hand holding the tear strip close to the input port 102, and then operate the solenoid valve 301. The solenoid valve 301 then draws air into the guide channel 2011 through the air inlet pipe 302, and discharges the gas to the outside through the exhaust pipe 303. After the solenoid valve 301 draws air, a negative pressure zone is formed at one end of the guide channel 2011 close to the input port 102. When the operator releases his hand, the tear strip will be sucked into the guide channel 2011 from the input port 102 under the action of external air pressure, and as the solenoid valve 301 is powered off, the tear strip falls into the collection chamber 2021 under the action of gravity. It is obvious that compared with the prior art in which the tear strip is easy to stick to the hand under the action of static electricity and is not easy to be thrown into the trash can, the embodiment of the present application arranges an electromagnetic pump at the input port 102 and forms a negative pressure zone, so that the tear strip is quickly collected into the collection chamber 2021 under the action of air pressure, which has the advantages of conveniently collecting the tear strip and helping to improve work efficiency.

[0035] Furthermore, if Figure 1 , Figure 2 and Figure 4As shown, the collecting assembly 20 includes a guide member 201 and a collecting barrel 202, the guide member 201 is placed in the accommodating cavity 101 and connected to the shell 10, the guide channel 2011 runs through from the top of the guide member 201 to the bottom of the guide member 201, the collecting barrel 202 has the collecting chamber 2021, and the top of the collecting chamber 2021 has an opening 20211, when the collecting barrel 202 is located directly below the guide member 201 and the top of the collecting barrel 202 is in contact with the bottom of the guide member 201, the two ends of the guiding channel 2011 are respectively connected to the input port 102 and the opening 20211; in addition, in the embodiment of the present application, the end of the guide member 201 close to the collecting barrel 202 is arranged in an expanded hole. That is, the maximum radial dimension of the end of the guide 201 away from the collecting tube 202 is smaller than the maximum radial dimension of the end of the guide 201 close to the collecting tube 202, and the radial dimension of the end of the guide 201 close to the collecting tube 202 is equal to the radial dimension of the collecting tube 202 at the opening 20211.

[0036] It should be noted that when the solenoid valve 301 stops working, the tear strip falls into the collection chamber 2021 of the collection tube 202 under the action of gravity. By designing the guide 201 and the collection tube 202 separately, when the tear strip in the collection chamber 2021 is piled to a predetermined height, the collection tube 202 can be taken out and the tear strip in the collection chamber can be dumped.

[0037] Furthermore, a condition is provided for the electromagnetic valve 301 to be energized when the operator's hand moves to the vicinity of the input port 102, such as Figure 2 and Figure 3 As shown, the packaging bag tear strip collection device further includes a sensor 40 and a controller 50, wherein the sensor 40 is electrically connected to the controller 50, and the controller 50 is electrically connected to an external power source and the solenoid valve 301, respectively. The sensor 40 is disposed at one side of the input port 102, and the controller 50 is disposed in the accommodating chamber 101. The sensor 40 is preferably a photoelectric sensor 40, which is electrically connected to an input port of the controller 50, and the solenoid valve 301 is electrically connected to an output port of the controller 50. When the operator's hand moves to the vicinity of the input port 102 and is irradiated by the photoelectric sensor 40, the photoelectric sensor 40 converts the optical signal into an electrical signal and transmits it to the controller 50, and the controller 50 energizes the solenoid valve 301, and the solenoid valve 301 draws air into the guide channel 2011 and forms a negative pressure zone at one end of the guide channel 2011 close to the input port 102.

[0038] Further, in order to facilitate each placement of the collection tube 202, Figure 1 and Figure 4 As shown, a cross-section of the collecting cylinder 202 is circular, and one side of the accommodating chamber 101 is provided with a pick-up and release opening 1011. A side wall of the accommodating chamber 101 away from the pick-up and release opening 1011 is provided with a plurality of limit blocks 1012 with V-shaped grooves. When the top of the collecting cylinder 202 coincides with the bottom of the guide 201, the outer wall of the collecting cylinder 202 abuts against the V-shaped groove on the limit block 1012. More specifically, in the embodiment of the present application, the number of the limit blocks 1012 is two. When the collecting cylinder 202 abuts against the limit blocks 1012, the two limit blocks 1012 are respectively opposite to the upper end and the lower end of the collecting cylinder 202.

[0039] Furthermore, in order to facilitate the operator to observe the stacking condition of the tear strips in the collection chamber 2021, as shown in FIG. Figure 1 As shown, the other side of the accommodating cavity 101 has a peephole 1013, the outer wall of the collecting tube 202 has a peephole 2022, and the collection device of the packaging bag tear strip also includes a transparent plate 2023, the material of the transparent plate 2023 includes but is not limited to an acrylic plate, the transparent plate 2023 is connected to the collecting tube 202 by bonding and closes the peephole 2022, and when the top of the collecting tube 202 coincides with the bottom of the guide 201, the peephole 2022 faces the peephole 1013.

[0040] Furthermore, in order to facilitate the operator to take the collection tube 202, Figure 1 As shown, the outer wall of the collecting tube 202 also has a handle 2024, and the handle 2024 is fixedly connected to the collecting tube 202, and its fixed connection method includes but is not limited to welding. When the top of the collecting tube 202 coincides with the bottom of the guide 201, the handle 2024 faces the pick-up and release port 1011.

[0041] Furthermore, in order to facilitate the operator to put the collection tube 202 into the Figure 1As shown, the peephole 2022 faces the peephole 1013, the handle 2024 faces the pick-up and release port 1011, a first magnet 1014 is provided on the side of the accommodating chamber 101 away from the pick-up and release port 1011, and a second magnet 2025 is provided on the side of the collecting tube 202 away from the handle 2024. The magnetic properties of the first magnet 1014 and the second magnet 2025 are opposite. When the top of the collecting tube 202 coincides with the bottom of the guide member 201, and the handle 2024 faces the pick-up and release port 1011, and the peephole 2022 faces the peephole 1013, the first magnet 1014 and the second magnet 2025 are attracted.

[0042] It should be noted that when the operator holds the collecting tube 202 and places the collecting tube 202 in the accommodating cavity 101, if there is a small circumferential angle deviation, under the action of the magnetic force of the first magnet 1014 and the second magnet 2025, the collecting tube 202 will be subjected to a circumferential force to guide the operator to place the collecting tube 202 at a specified position.

[0043] Furthermore, in order to avoid interference between the movements of the first magnet 1014 and the second magnet 2025 when the collecting tube 202 rotates circumferentially, a side of the second magnet 2025 close to the first magnet 1014 is an arc surface.

[0044] Furthermore, in order to place the housing 10 more stably, as Figure 1 As shown, the bottom of the housing 10 has at least three legs 103 , and at least one of the legs 103 is not aligned with the line connecting the other two legs 103 .
