Description

Technical Field

[0001] This invention relates to the field of strip powder back-sealing packaging machine technology, specifically a strip powder back-sealing packaging machine based on multi-directional motion control. Background Technology

[0002] The multi-directional motion control strip powder back-sealing packaging machine is an automated packaging equipment that integrates multi-directional motion control technology, strip powder packaging process requirements, and back-sealing packaging machine features.

[0003] Currently, for packaging strip-shaped powders, the width data of the packaging film is usually input into the PLC controller first, and then the size of the packaging bag is calculated by the algorithm. For the support components of the packaging film, different support components need to be replaced for different packaging bag sizes, which is not convenient for flexible adjustment according to the width of the packaging film. Moreover, when guiding the packaging film, it is difficult to remove static electricity on the surface of the packaging film and realize deviation alarm at the same time, which increases the difficulty and workload of workers and reduces the automation efficiency of the packaging equipment.

[0004] Combining the above issues, we find that existing back-sealing packaging machines on the market cannot simultaneously avoid the problems mentioned above. Even if they can be solved, they require external tools, thus failing to achieve the desired effect.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-11 The present invention provides a technical solution: a multi-directional motion control strip powder back-sealing packaging machine, including a machine body, a support frame 11 fixedly connected to the top of the packaging machine body 1, an unwinding roller 12 rotatably connected to the top of the support frame 11, a packaging film 14 wrapped around the surface of the unwinding roller 12, a controller 13 fixedly connected to one side of the support frame 11, the controller 13 adopts PLC technology, which can realize the automated control of the multi-directional process of the packaging machine body 1, a width self-adjusting mechanism 2 is provided on one side of the packaging machine body 1, and an anti-static guiding mechanism 3 is provided on one side of the packaging machine body 1; The width self-adjustment mechanism 2 includes a width self-measuring unit 21, which is disposed on the top of the support frame 11. The width self-measuring unit 21 is used to automatically measure the width of the packaging film 14. The width self-adjusting mechanism 2 also includes a width adjustment unit 22, which is located on one side of the packaging machine body 1. The width adjustment unit 22 includes two support molds 2201, and the width adjustment unit 22 automatically adjusts the distance between the two support molds 2201 according to the width of the packaging film 14.

[0023] As a further definition of the width self-adjustment mechanism 2 of the present invention, the width self-measuring unit 21 includes a first support block 2101 fixedly connected to the top of the support frame 11. A first electric push rod 2102 is fixedly connected to the inner wall of the first support block 2101. A positioning block 2103 is fixedly connected to the telescopic end of the first electric push rod 2102. Two sliding rods 2104 are slidably connected to the inner wall of the positioning block 2103. One end of the two sliding rods 2104 is fixedly connected to a first bonding plate 2105. A first laser ranging sensor 2106 is fixedly connected to the inner wall of the first bonding plate 2105. A second support block 2107 is fixedly connected to the top of the support frame 11. The second support block 2107 is arranged opposite to the first support block 2101. A slide rod 2108 is slidably connected to the inner wall of the packaging machine 12. One end of the slide rod 2108 is fixedly connected to a second bonding plate 2109. A first laser rangefinder 2106 works in conjunction with the second bonding plate 2109. The opposite sides of the first bonding plate 2105 and the second bonding plate 2109 are respectively bonded to both sides of the packaging film 14 on the surface of the unwinding roller 12. By setting a width self-measuring unit 21, the width of the packaging film 14 to be packaged can be automatically measured. The measured width data is imported into the controller 13 by the first laser rangefinder 2106, realizing the automatic input of the width data of the packaging film 14, replacing manual input, reducing the difficulty of operation for workers and reducing their workload, and improving the automation efficiency of the packaging machine body 1.

[0024] A placement groove 2110 is provided on one side of the positioning block 2103. A first pressure sensor 2111 is fixedly connected to the inner wall of the placement groove 2110. A first input rod 2112 is fixedly connected to one side of the first bonding plate 2105. The first input rod 2112 contacts the input end of the first pressure sensor 2111. By setting the placement groove 2110 and cooperating with the first pressure sensor 2111 and the first input rod 2112, when the first bonding plate 2105 contacts the packaging film 14 on the surface of the unwinding roller 12, the blocking force of the packaging film 14 pushes the first bonding plate 2105 to move in the opposite direction, pushing the first input rod 2112 to squeeze the input end of the first pressure sensor 2111, thereby generating a pressure value. Then, the first pressure sensor 2111 converts the pressure value into an electrical signal, and the controller 13 controls the first electric push rod 2102 to stop extending, ensuring that the first bonding plate 2105 and the packaging film 14 are tightly bonded, thereby improving the accuracy of the measurement data.

[0025] A first spring 2113 is slidably sleeved on the surface of the sliding rod 2104. The two ends of the first spring 2113 are fixedly connected to the opposite sides of the positioning block 2103 and the first bonding plate 2105, respectively. A second spring 2114 is slidably sleeved on the surface of the sliding rod 2108. One end of the second spring 2114 is fixedly connected to the surface of the sliding rod 2108, and the other end of the second spring 2114 is fixedly connected to one side of the second bonding plate 2109. By setting the first spring 2113, the distance between the positioning block 2103 and the first bonding plate 2105 can be elastically adjusted. The reaction force of the first spring 2113 enables the bonding between the first bonding plate 2105 and the packaging film 14. By setting the second spring 2114, the distance between the second bonding plate 2109 and the second support block 2107 can be elastically adjusted. The reaction force of the second spring 2114 enables the tight bonding between the second bonding plate 2109 and the packaging film 14.

[0026] The specific implementation of this embodiment is as follows: When packaging the powder, the worker installs the unwinding roller 12 with the packaging film 14 on the top of the support frame 11. One side of the packaging film 14 is tightly attached to the second bonding plate 2109. When the second bonding plate 2109 contacts the packaging film 14, the pushing force of the packaging film 14 pushes the second bonding plate 2109, and the second bonding plate 2109 pushes the slide bar 2108. The movement of the slide bar 2108 compresses the first spring 2113, thereby realizing the second bonding... The distance between plate 2109 and the second support block 2107 is elastically adjusted. After the unwinding roller 12 is installed, the controller 13 starts the first electric push rod 2102. The telescopic end of the first electric push rod 2102 extends, pushing the positioning block 2103, the two sliding rods 2104, and the first bonding plate 2105 to move. After the first bonding plate 2105 contacts the packaging film 14, as the first electric push rod 2102 continues to extend, the first bonding plate 2105 generates a reverse force, which exerts a force on the two sliding rods 2107. 104 pushes in the reverse direction, simultaneously compressing the two first springs 2113 to achieve elastic adjustment of the distance between the first bonding plate 2105 and the positioning block 2103. The reverse movement of the first bonding plate 2105 drives the first input rod 2112 to press the input end of the first pressure sensor 2111, thereby generating a pressure value. Subsequently, the first pressure sensor 2111 converts the pressure value into an electrical signal, which controls the first electric push rod 2102 to stop extending through the controller 13, ensuring a tight fit between the first bonding plate 2105 and the packaging film 14, thereby improving the accuracy of the measurement data. Then, the distance between the first bonding plate 2105 and the second bonding plate 2109 is measured by the first laser rangefinder 2106, thereby realizing the automatic measurement of the width of the packaging film 14 and improving the efficiency of automation. The first laser rangefinder 2106 adopts Banner Q5XKLAF2000, which emits laser light and receives reflected light, and calculates using triangulation or phase difference methods.

[0027] Example 2: Please refer to Figures 1-11 The present invention provides a technical solution: a multi-directional motion control strip powder back-sealing packaging machine, which makes corresponding improvements to the technical problems mentioned in the background art.

[0028] As a further definition of the width self-adjusting mechanism 2 of the present invention, trapezoidal grooves 2202 are provided on the surfaces of both support molds 2201. A trapezoidal block 2203 is slidably connected to the inner cavity of both trapezoidal grooves 2202. A connecting rod 2204 is fixedly connected to one side of the trapezoidal block 2203. The surface of the connecting rod 2204 is slidably connected to the opposite sides of the two support molds 2201. An extension rod 2205 is fixedly connected to one side of the packaging machine body 1. A second electric push rod 2206 is fixedly connected to the bottom of the extension rod 2205. The telescopic end of the second electric push rod 2206 is fixedly connected to the top of the connecting rod 2204. The opposite sides of the two support molds 2201... Guide blocks 2207 are fixedly connected to both sides, and a sliding groove 2208 is opened at one end of the extension rod 2205. Both guide blocks 2207 are slidably connected to the inner cavity of the sliding groove 2208. A second laser range sensor 2213 is fixedly connected to one side of one of the support molds 2201. By setting the width adjustment unit 22, the distance between the two support molds 2201 can be automatically adjusted. According to the width data transmitted to the controller 13 by the width self-testing unit 21, the width to be formed by the two support molds 2201 is calculated by setting the program, thereby realizing the support of packaging films 14 of different sizes and realizing the automation of width adjustment.

[0029] A guide rod 2209 is fixedly connected to the inner cavity of the sliding groove 2208. The inner walls of the two guide blocks 2207 are slidably connected to the surface of the guide rod 2209. A third spring 2210 is fixedly connected to one side of each of the two guide blocks 2207. The opposite sides of the two third springs 2210 are fixedly connected to the opposite surfaces of the inner side of the sliding groove 2208. The third springs 2210 are slidably sleeved on the surface of the guide rod 2209. By setting the guide rod 2209 and the third spring 2210 to work together, the guide rod 2209 can guide the two guide blocks 2207 and increase the stability of the guide blocks 2207 when they move. When the guide blocks 2207 move, they compress the third spring 2210. When the guide blocks 2207 lose the thrust of lateral movement, they lose the compressive force on the third spring 2210. Through the reaction force of the third spring 2210, the two guide blocks 2207 can be reset.

[0030] Both support molds 2201 have notches 2211 on opposite sides. The inner cavity of the notch 2211 is fitted with a feed nozzle 2212 in non-contact. The feed nozzle 2212 is connected to the feeding component of the packaging machine body 1. By setting the notch 2211 and the feed nozzle 2212 in cooperation, the optimal setting of the powder feeding channel can be ensured, and the smooth operation of powder packaging can be ensured.

[0031] The specific implementation of this embodiment is as follows: After the width of the packaging film 14 is transmitted to the controller 13 through the width self-testing unit 21, the width to be formed by the two support molds 2201 is calculated by the preset program in the controller 13, thereby achieving optimal support for the packaging film 14. Taking the increase of width as an example, the controller 13 then activates the second electric push rod 2206 at the bottom of the extension rod 2205. Through the extension of the telescopic end of the second electric push rod 2206, the connecting rod 2204 is pushed to move. The movement of the connecting rod 2204 causes the trapezoidal block 2203 to move down in the inner cavity of the trapezoidal groove 2202, thereby realizing the two support molds 2201 As the distance between them increases, the relative movement of the two support molds 2201 causes the two guide blocks 2207 to move relative to each other on the surface of the guide rod 2209. The movement of the guide blocks 2207 compresses the third spring 2210 until the second laser rangefinder 2213 measures that the distance between the two support molds 2201 has reached the set distance. Then, the extension of the second electric push rod 2206 is stopped, thereby realizing the automatic adjustment of the distance between the two support molds 2201 according to the width of the packaging film 14, which improves the automation efficiency. The second laser rangefinder 2213 here is the same as the first laser rangefinder 2106.

[0032] Example 3: Please refer to Figures 1-11 The present invention provides a technical solution: a multi-directional motion control strip powder back-sealing packaging machine, which makes corresponding improvements to the technical problems mentioned in the background art.

[0033] As a further definition of the antistatic guiding mechanism 3 of the present invention, the antistatic guiding mechanism 3 includes two connecting plates 301 fixedly connected to the inner side of the support frame 11. A defective annular block 302 is fixedly connected to the surface of the two connecting plates 301. A receiving cavity 303 is formed at the top of the defective annular block 302. A plurality of ion needles 304 are fixedly connected to the inner wall of the receiving cavity 303 at equal intervals. A plurality of connecting tubes 305 are fixedly connected to the surface of the defective annular block 302. One end of each connecting tube 305 is connected to the receiving cavity 303, and the other end of each connecting tube 305 is fixedly connected to an annular tube 306. An inlet / outlet is fixedly connected to the surface of the annular tube 306. Guide boxes 308 are fixedly connected to the opposite ends of the air pipe 307 and the incomplete annular block 302. Slider 309 is slidably connected to the inner cavity of the two guide boxes 308. A round rod 310 is fixedly connected to one side of the slider 309. A locking block 311 is fixedly connected to one end of the round rod 310. A roller 312 is rotatably connected to the inner side of the locking block 311 through a rotating shaft. The two rollers 312 are used to clamp and guide the packaging film 14. By setting the anti-static guiding mechanism 3, the packaging film 14 can be guided to prevent deviation while removing static electricity from the surface of the packaging film 14. The deviation of the packaging film 14 can also be automatically monitored, thus improving the automation efficiency of the packaging machine body 1.

[0034] Two second pressure sensors 313 are fixedly connected to the inner side of the guide box 308. Spring telescopic rods 314 are fixedly connected to both sides of the slider 309. The telescopic ends of the two spring telescopic rods 314 are respectively in contact with the input ends of the second pressure sensors 313. By setting the second pressure sensors 313 and spring telescopic rods 314 to work together, when the slider 309 moves laterally, it drives the spring telescopic rods 314 to move laterally, so that the second pressure sensors 313 generate pressure values, thereby realizing the monitoring of the deviation of the packaging film 14. The spring telescopic rod 314 consists of an inner rod, an outer rod and a spring. The inner rod is slidably sleeved in the inner cavity of the outer rod, and the spring is located in the inner cavity of the outer rod. The two ends of the spring are respectively fixedly connected to one end of the inner rod and the inner bottom of the outer rod.

[0035] A T-shaped groove 315 is provided on the inner side of the guide box 308. A T-shaped block 316 is fixedly connected to the surface of the slider 309. The surface of the T-shaped block 316 is slidably connected to the inner cavity of the T-shaped groove 315. A guide groove 317 is provided on the top of the incomplete annular block 302. The guide groove 317 is used to guide the ionized air to the surface of the packaging film 14. By setting the T-shaped groove 315 and the T-shaped block 316 in cooperation, the slider 309 can be stably guided. The guide groove 317 can ensure that the ionized air is blown to the surface of the packaging film 14, thereby improving the efficiency of static electricity removal.

[0036] The specific implementation of this embodiment is as follows: During installation, the packaging film 14 is used for heat pressing, with the spine portion of the packaging bag clamped between two rollers 312, and the remaining portion passing through the middle of the self-damaged annular block 302. If the packaging film 14 deviates during transport, the rollers 312 will shift laterally. This lateral movement of the rollers 312 causes the locking block 311 to shift laterally, which in turn causes the round rod 310 to shift laterally. This shift of the round rod 310 causes the slider 309 to shift laterally, which in turn causes the T-shaped block 316 to slide within the T-groove 315, achieving stable movement of the slider 309. The movement of the slider 309 causes the spring telescopic rod 314 to move, which in turn compresses the input end of one of the second pressure sensors 313, causing... The second pressure sensor 313 generates a pressure value, which is converted into an electrical signal. The controller 13 stops the operation of the packaging machine body 1 to avoid a large amount of waste. When guiding the packaging film 14, the controller 13 energizes the ion needle 304 in the receiving cavity 303 of the defective annular block 302, and supplies air to the air inlet pipe 307 through an external air supply device. The air inlet pipe 307 transmits air to the annular pipe 306, which disperses the air into several connecting pipes 305. The air is then transmitted to the receiving cavity 303 through the connecting pipes 305. The ion needle 304 ionizes the air, generating positive and negative ions.
