Description

Technical Field

[0001] This utility model relates to the field of sealing technology for drip coffee bags, specifically a sealing device for drip coffee bags. Background Technology

[0002] Drip coffee is a portable brewing method. Drip coffee can be hung on the rim of a cup via a paper bag on the outside of the packaging, making it convenient to fully brew the coffee powder and allowing people to enjoy the taste of hand-drip coffee anytime.

[0003] A drip bag coffee packaging machine, disclosed in CN220555408U, features a conveyor belt that facilitates automatic unloading of packaged coffee, thereby improving packaging efficiency, reducing coffee powder spillage, and allowing for easy adjustment of the two limiting sleeves along the chute. This allows for adjustment of the distance between the two limiting sleeves according to the specifications of the packaging bag, enabling the packaging machine to adapt to various packaging bag sizes and improving its functional adaptability.

[0004] This drip bag coffee packaging machine has two limiting sleeves that slide along the chute, allowing for easy adjustment of the distance between the two limiting sleeves according to the size of the packaging bag. However, this device only limits the position of the drip bag packaging bag through the limiting sleeves and cannot clamp and fix the drip bag packaging bag. This makes it easy for the coffee packaging bag to shift and fall off when the conveyor belt is running, affecting the sealing accuracy. Therefore, it needs to be improved. Utility Model Content

[0009] Preferably, the inner side of the fixed frame is provided with a groove corresponding to the movement trajectory of the support member, and the support member is slidably connected inside the groove. Through the groove, the support member can rotate inside the fixed frame. The support member can support the load-bearing plate, making the load-bearing plate more stable during rotation.

[0010] Preferably, the limiting component includes a placement box, which is fixedly connected to the load-bearing plate. A sliding rod is slidably connected inside the placement box.

[0011] Preferably, the outer side of the spring is fixedly connected to the inner side of the placement box, and the inner side of the spring is fixedly connected to the outer side of the clamping plate. Through the elastic force of the spring, the spring can drive the clamping plate to move, so that the clamping plate can clamp the outer part of the ear loop packaging bag near the top, making the ear loop packaging bag more stable when it is sealed.

[0012] Preferably, the inner side of the placement box is provided with a limiting groove corresponding to the movement trajectory of the clamping plate, and the clamping plate is slidably connected inside the limiting groove. The limiting groove can limit the clamping plate and make the clamping plate more stable during movement.

[0013] Preferably, the sealing mechanism includes a support frame, which is fixedly connected to the top left side of a fixed frame. A load-bearing plate is fixedly connected to the top left side of the support frame. A rotating motor is fixedly connected to the top of the load-bearing plate. A threaded rod is fixedly connected to the bottom of the rotating motor. The bottom of the threaded rod is rotatably connected to the top of the fixed frame.

The limiting rods can limit the threaded plate, making the threaded plate more stable during the lifting and lowering process.

[0015] Compared with the prior art, this utility model provides a sealing device for drip coffee packaging, which has the following beneficial effects:

[0016] 1. The drip bag coffee packaging sealing device uses a rotating component driven by a drive motor to drive the rotating shaft, drive gear and rotating gear transmission, which can precisely control the rotation of the load-bearing plate, so that the infrared receiver on the load-bearing plate can quickly align with the infrared transmitter of the sealing mechanism, and achieve precise positioning of the drip bag packaging bag.

[0017] The limiting component uses the elastic force of the spring to stably clamp the ear loop packaging bag. When the ear loop packaging bag is placed, the pull plate drives the clamping plate to open against the spring force. After placement, the spring returns to its original position to clamp the bag, limiting its position and ensuring the smooth progress of the subsequent sealing process.

[0018] 2. This drip coffee packaging sealing device uses a rotating motor to drive a threaded rod to rotate, causing the threaded plate to move up and down along the threaded rod under the restriction of the limiting rod. This allows for precise adjustment of the height of the lifting plate and the sealing mold, making it suitable for drip coffee packaging bags of different thicknesses and specifications. The cylinder pushes the push plate to drive the sealing mold to perform the sealing action, which can flexibly control the sealing pressure to ensure a tight and secure seal and improve the sealing quality.

[0031] Example 1

[0032] Please see Figure 1-7 This utility model provides a technical solution: a sealing device for drip coffee packaging, including a fixed frame 1, a sealing mechanism 3 is provided on the top left side of the fixed frame 1, a PLC controller 2 is fixedly connected to the front of the fixed frame 1, and a rotation limit mechanism 4 is provided on the top right side of the fixed frame 1.

[0040] Example 3

[0041] Please see Figure 1-7 Furthermore, based on Embodiment 1, the sealing mechanism 3 further includes a support frame 31, which is fixedly connected to the top left side of the fixed frame 1. A load-bearing plate 35 is fixedly connected to the top left side of the support frame 31. A rotating motor 36 is fixedly connected to the top of the load-bearing plate 35. A threaded rod 32 is fixedly connected to the bottom of the rotating motor 36. The bottom of the threaded rod 32 is rotatably connected to the top of the fixed frame 1. A threaded plate 34 is threadedly connected to the outer periphery of the threaded rod 32. A limit rod 33 is slidably connected inside the threaded plate 34. The threaded plate 34 is slidably connected to the inner side of the support frame 31. A lifting plate 37 is fixedly connected to the right side of the threaded plate 34. A support plate 39 is fixedly connected to the top of the lifting plate 37. A cylinder 38 is fixedly connected to the outer side of the support plate 39. A push plate 301 is fixedly connected to the inner side of the cylinder 38. A sealing mold 303 is fixedly connected to the bottom of the push plate 301. An infrared emitter 302 is fixedly connected to the bottom right side of the lifting plate 37.

[0042] Furthermore, there are two limit rods 33. The tops of the two limit rods 33 are fixedly connected to the bottom of the load-bearing plate 35, and the bottoms of the two limit rods 33 are fixedly connected to the top of the fixed frame 1. The limit rods 33 can limit the threaded plate 34, making the threaded plate 34 more stable during the lifting and lowering process.

[0043] In actual operation, when this device is used, the operator manually pushes the two pull plates 421, which push the clamping plate 427 to move. This allows the clamping plate 427 to compress the spring 428 and the slide bar 425, placing the coffee-filled drip bag 426 into the placement box 422. The force applied to the pull plates 421 is then released, and the clamping plate 427 clamps and fixes the drip bag 426 through the elastic force of the spring 428. This makes the drip bag 426 more stable when the load-bearing plate 414 drives the placement box 422 to rotate.

[0044] The PLC controller 2 turns on the infrared transmitter 302 and the drive motor 411, causing the drive motor 411 to drive the drive gear 412 to rotate via the rotating shaft 419. The drive gear 412 then drives the rotating rod 416 to rotate via the rotating gear 418. The rotating rod 416 then drives the load-bearing plate 414 to rotate, which in turn drives the placement box 422 to rotate. When the load-bearing plate 414 drives the receiver 415 to rotate to the bottom of the infrared transmitter 302, it transmits a signal to the PLC controller 2, causing the PLC controller 2 to stop the drive motor 411. This allows the ear loop packaging bag 426 to remain at the bottom of the sealing mold 303, and the sealing mold 303 is then energized and heated.

[0045] The PLC controller 2 turns on the rotating motor 36, causing the rotating motor 36 to drive the threaded rod 32 to rotate. The threaded rod 32 drives the lifting plate 37 to move downward through the threaded plate 34. The lifting plate 37 drives the cylinder 38 and the push plate 301 to move downward through the support plate 39. The push plate 301 drives the sealing mold 303 to move downward. The sealing mold 303 moves to the left and right sides of the ear loop packaging bag 426. The PLC controller 2 turns on the cylinder 38, causing the two cylinders 38 to drive the push plate 301 to move inward. The push plate 301 can drive the sealing mold 303 to move, so that the sealing mold 303 can seal the ear loop packaging bag 426.

[0046] After the ear loop packaging bag 426 is sealed, the drive motor 411 is turned on again by the PLC controller 2, so that the drive motor 411 can drive the drive gear 412 to rotate through the rotating shaft 419. The drive gear 412 drives the rotating rod 416 to rotate through the rotating gear 418. The rotating rod 416 drives the supporting plate 414 to rotate. The supporting plate 414 drives the placement box 422 to rotate. The placement box 422 drives the sealed ear loop packaging bag 426 to rotate, so that the staff can pick up the ear loop packaging bag 426. The PLC controller 2 model is Siemens S7-1200, the infrared transmitter 302 model is Sharp GP2Y0A21YK0F, and the receiver 415 model is TSOP1738.
