Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to an automated paper towel packaging machine. Background Technology

[0002] Paper towels are everyday consumer goods. Their components include chlorine, bleach, alcohol, wood pulp, and renewable resources. There are many types of paper towels, including facial tissues and toilet paper. Facial tissues are popular due to their convenience. Currently, facial tissues need to be packaged in bags, then sealed and transported to their destination. In the actual packaging process, a bag with one open end is selected. Workers then hold the bag and move it to a packaging machine. The machine pushes a fixed number of paper towels into the bag, and finally, it is heat-sealed to complete the packaging.

[0003] Chinese utility model patent CN218704365U discloses a tissue packaging machine that facilitates sealing. The machine clamps and repeatedly drags the packaging bag to the upper surface of a pallet. Then, a rotating arc arm causes the cut packaging bag to wrap around the tissue paper, forming a box-shaped bag ready for sealing. The box-shaped bags are then conveyed one by one to the sealing area via a conveyor belt. A concave heating block moves downwards via the piston rod of a fifth electric cylinder and is guided by a heat-conducting rod, allowing for simultaneous and rapid sealing of both ends and sides of the box-shaped bag. This sealing equipment is miniaturized and semi-automated, making it suitable for promotion by small and medium-sized enterprises.

[0004] There are some other problems with the device during use. For example, when packaging wet wipes, there may be insufficient or excessive packaging. Sometimes, the wet wipes may not contain enough soaking liquid, resulting in substandard packaging. Utility Model Content

[0063] Example 1:

[0064] This embodiment provides an automated paper towel packaging machine, which has the following technical features.

[0065] Please see Figure 1-6 An automated tissue packaging machine includes a mounting plate 100, on which a conveying mechanism is fixedly mounted. A packaging mechanism is located on one side of the conveying mechanism, and the packaging mechanism includes:

[0066] Mounting frame 410 is located on one side of the conveying mechanism;

[0067] The first cylinder 420 is fixedly mounted on the mounting frame 410;

[0068] Push plate 430 is fixedly mounted on the output shaft of first cylinder 420;

[0069] Weighing plate 440 is fixedly mounted on the base plate of mounting frame 410;

[0070] The third motor 450 is fixedly mounted on the top plate of the mounting frame 410;

[0071] A bidirectional screw 460 is fixedly connected at one end to the output shaft of the third motor 450;

[0072] The guide rod 470 is located inside the mounting frame 410, and the guide rod 470 is arranged parallel to the bidirectional screw 460;

[0073] Threaded sleeve 461 is fitted into the double-acting screw 460 and guide rod 470;

[0074] The expansion plate 480 is fixedly connected to two threaded sleeves 461;

[0075] The sealing mechanism is mounted on the mounting frame 410.

[0076] Further sealing mechanisms include:

[0077] Limiting rod 491 is fixedly connected to mounting frame 410;

[0078] The sliding cylinder 492 is slidably fitted onto the limiting rod 491;

[0079] Connecting plate 493 is fixedly connected to two sliding cylinders 492 at both ends;

[0080] The heat sealing knife 494 is fixedly connected to the bottom of the connecting plate 493;

[0081] The second cylinder 495 is fixedly connected to the top of the mounting frame 410, and the output shaft of the second cylinder 495 is fixedly connected to the connecting plate 493.

[0082] It should be noted that an alarm sensor is installed below the weighing plate 440. When the paper towel is transferred to the weighing plate 440, the weighing plate 440 weighs it. Once the weight of the paper towel reaches the standard, the first cylinder 420 is controlled to transfer the paper towel. If the weight of the paper towel does not meet the standard, the alarm sensor can sound an alarm, thereby reminding the staff to sort the paper towel. One side of the weighing plate 440 and the supporting plate 480 is flush with the upper surface of the conveyor belt 240, and the other side is attached to the inner wall of the mounting frame 410. This makes it convenient for the paper towel to be flush with one side when it is transferred to the weighing plate 440 and the supporting plate 480, which makes it easy to push the paper towel into the packaging bag. In addition, the heat sealing knife 494 can also be used with a temperature adjustment device, which makes it convenient to adjust the temperature of the heat sealing knife 494 so that the heat sealing knife 494 can adapt to the sealing of different packaging materials.

[0083] Further configurations include:

[0084] Side plates 210 are fixedly connected to both sides of the upper surface of the mounting plate 100;

[0085] The first motor 220 is fixedly connected to the outside of one of the side plates 210;

[0086] Two drive rollers 230 are provided, one of which is fixedly connected to the output shaft of the first motor 220;

[0087] Conveyor belt 240, transmission sleeve rotates on two transmission rollers 230;

[0088] The mounting frame 410 is fitted to the side plate 210, and the fitting position is set as an opening. A pushing mechanism is provided between the conveying mechanism and the packaging mechanism.

[0089] Further, the promoting agencies include:

[0090] The support frame 310 is fixedly installed on the outside of the mounting frame 410 and the side plate 210;

[0091] A transverse groove 320 is formed through the top of the support frame 310;

[0092] The upright plate 330 is fixedly installed on both sides of the top plate of the support frame 310;

[0093] A one-way screw 340 is mounted on two vertical plates 330 at its two ends;

[0094] The second motor 370 is fixedly connected to one end of the one-way screw 340;

[0095] The slide plate 350 is threaded onto the one-way screw 340, and the two sides of the slide plate 350 slide against the inside of the transverse groove 320.

[0096] The adjustment mechanism is located on one side of the support frame 310 and below the one-way screw 340.

[0097] It should be noted that the second motor 370 is a forward and reverse motor, and the second motor 370 can drive the slide plate 350 to move to any position in the transverse groove 320.

[0098] Further adjustments include:

[0099] The limiting groove 361 is formed on the upper surface of the side plate of the support frame 310;

[0100] The threaded post 362 is fixedly connected inside the limiting groove 361;

[0101] Sliding block 364 is fitted onto threaded post 362;

[0102] Spring 363 is fixedly connected at one end to the lower surface of sliding block 364, and spring 363 is fitted on the outside of threaded post 362;

[0103] The limiting block 365 is positioned above the sliding block 364, and the limiting block 365 is slidably fitted onto the threaded post 362;

[0104] Nut 366 is threaded onto threaded post 362.

[0105] It should be noted that by changing the position between the nut 366 and the threaded post 362, the height of the sliding block 364 and the limiting block 365 can be changed. The side of the sliding block 364 that contacts the limiting block 365 has a circular hole. The end of the one-way screw 340 away from the second motor 370 is fitted into the circular hole. The one-way screw 340 and the second motor 370 can be quickly removed for maintenance by using the nut 366. At the same time, by controlling the connection position between the nut 366 and the threaded post 362, the height of the one-way screw 340 can be adjusted, thereby changing the distance between the bottom of the slide plate 350 and the conveyor belt 240, thereby controlling the thickness and number of tissues pushed by the slide plate 350 onto the load-bearing plate.

[0106] Furthermore, the weighing plate 440 is flush with the conveyor belt 240, and the bottom of the mounting frame 410 is provided with a limit hole. A stop block 441 is fixedly connected to the bottom of the weighing plate 440, and the stop block 441 slides inside the limit hole.

[0107] It should be noted that the limiting hole is set on the side closer to the push plate 430. This way, when the push plate 430 pushes the paper towel, it will not affect the weighing plate 440's weighing of the paper towel. It also makes it convenient to inspect and maintain the alarm sensor and the weighing device.

[0108] Further configurations include the first motor 220, the second motor 370, the first cylinder 420, the third motor 450, and the second cylinder 495 being electrically connected to the control center.

[0109] It should be noted that the first motor 220, the second motor 370, the first cylinder 420, the third motor 450, the second cylinder 495, and the alarm sensor are all electrically connected to the control center. This allows for manual control of the cycle time and number of cycles for each component, as well as changes in their parameters.

[0110] Working principle: A conveying mechanism and a packaging mechanism are provided on the mounting plate 100. The side plate 210 of the conveying mechanism is connected to the side of the mounting frame 410 of the packaging mechanism. This allows for the continuous conveying of tissues when the first motor 220 drives the conveying roller and the conveyor belt 240. A pushing mechanism 300 is provided above the conveying and packaging mechanisms. The support frame 310 of the pushing mechanism 300 spans the packaging and conveying mechanisms. A through-slot 320 is provided at the top of the support frame 310. Vertical plates 330 are fixed on the support frames 310 on both sides of the slot 320. One-way screws 340 are provided on the two vertical plates 330. The output shaft of the second motor 370 is fixedly connected to one end of the one-way screw 340. A sliding plate 350 is threadedly connected to the one-way screw 340. This allows the position of the sliding plate 350 to be controlled when the second motor 370 rotates. The sliding plate 350 can then push the tissues on the conveyor belt 240. The tissues are pushed onto the weighing plate 440 of the packaging mechanism. Once the weighing plate 440 detects that the tissues' weight is within acceptable limits, it controls the third motor 450 to drive the bidirectional screw 460 to rotate, thereby opening the upper and lower supporting plates 480. This allows the packaging bag currently mounted on the supporting plates 480 to be opened. Simultaneously, the first cylinder 420 drives the push plate forward, pushing the tissues on the weighing plate 440 into the interior of the upper and lower supporting plates 480, ultimately pushing the tissues into the packaging bag. Inside the bag, the second cylinder 495 drives the sliding cylinder 492 and the connecting plate 493 to slide along the direction of the limiting rod 491, thereby enabling the heat sealing knife 494 on the connecting plate 493 to seal the packaging bag. After the heat sealing knife 494 seals the packaging bag, the low-voltage motor controls the bidirectional screw to rotate in the opposite direction. Under the limit of the guide rod 470, the upper and lower support plates 480 can be merged, making it convenient for the staff to put the packaging bag on the support plate 480.

[0111] In summary, this automated tissue packaging machine, through the conveying mechanism and the packaging mechanism set on the mounting plate 100, and the push mechanism set between the conveying mechanism and the packaging mechanism, can continuously convey tissues to the designated position. After the push mechanism pushes the tissues onto the weighing plate 440 inside the mounting frame 410, the expansion plate 480 is opened by the third motor 450. After the weighing plate 440 detects qualified products, the first cylinder 420 can push the tissues onto the expansion plate 480. Finally, the sealing mechanism seals the packaging bag.

[0112] In summary, this automated tissue packaging machine, by providing an adjustment mechanism at one end of the support frame 310, allows the use of the spring 363, nut 366, and threaded post 362 of the adjustment mechanism to change the distance between the slide plate 350 and the conveyor belt 240, thereby controlling the thickness of the tissue paper sliding onto the weighing plate 440, and thus facilitating the control of the weight of the packaged tissue paper.
