[0002] When packaging some fluffy products, such as quilts, plush toys, needles and other products, the products themselves are filled with a lot of fluffy items to make the products soft. However, this makes the products very large and takes up a lot of space when loading. Therefore, they need to be compressed to reduce the volume, so a pressing plate is used for the operation.

[0003] At present, the method of compressing product packaging is to put a packaging bag on the outside of the product. In order to reduce the volume, the pressure plate will be controlled to press the packaging bag to squeeze out the air inside the packaging bag, so that the product can be compressed and the volume can be reduced.

[0004] Although the above method can compress the product and reduce its volume, in actual operation, the packaging bag is squeezed by a pressing plate, but the product is placed inside the packaging bag and has a certain thickness. This causes the upper and lower inner walls of the packaging bag to be unable to fit together, and air will remain inside and cannot be discharged, which will affect the processing effect of the product. Therefore, a packaging machine pressing plate is proposed to solve the above problem. Utility Model Content

[0027] Example

[0028] Reference Figure 1-Figure 5The utility model provides a technical solution: a packaging machine pressing plate, including a bottom plate 1 and an extrusion mechanism 3, a support frame 2 is fixedly installed on the upper surface of the bottom plate 1, the extrusion mechanism 3 includes a cylinder 31, the cylinder 31 is fixedly installed on the top of the support frame 2, the telescopic end of the cylinder 31 is fixedly connected to the connecting rod 311, one end of the connecting rod 311 is installed with an extrusion plate 312, a rectangular hole 321 is opened on the upper surface of the extrusion plate 312, the inside of the rectangular hole 321 is slidably connected to a moving block 322, one end of the moving block 322 is rotatably installed with a rolling wheel 32, a pressing block 33 is slidably installed on the outside of the connecting rod 311, the bottom of the pressing block 33 is rotatably connected to the connecting plate 331, the connecting plate 331 is rotatably connected to the moving block 322, a through hole 341 is opened on one side of the support frame 2, and a driving wheel 34 is rotatably installed inside the through hole 341.

[0029] In a preferred embodiment, the inner wall of the rectangular hole 321 is fixedly connected to the positioning block 4, and a slide groove 5 is provided on the outer side of the moving block 322. The positioning block 4 is arranged inside the slide groove 5 and is slidably connected to the slide groove 5. The length of the moving block 322 matches the length of the rectangular hole 321. By controlling the movement of the moving block 322, the device will drive the rolling wheel 32 to roll on the outside of the packaging bag. In order to make the moving block 322 move stably, the positioning block 4 is fixedly installed on the inner wall of the rectangular hole 321, and a slide groove 5 is provided on the side of the moving block 322. The positioning block 4 is slidably installed inside the slide groove 5 to control the stable movement of the moving block 322, thereby driving the rolling wheel 32 to squeeze and exhaust the packaging bag.

[0030] In a preferred embodiment, a driving plate 6 is fixedly installed on the driving wheel 34, and an elastic clip 7 is fixedly installed inside the through hole 341. The driving plate 6 is clamped on the inner side of the elastic clip 7. When the device is in use, in order to limit the pressing block 33 so that the pressing block 33 cannot fall easily, the driving plate 6 is used to support the pressing block 33. At the same time, one of the driving plates 6 on the driving wheel 34 is clamped on the inner side of the elastic clip. By clamping the driving plate 6 with two elastic clips 7, the driving plate 6 can stably support the pressing block 33 so that the pressing block 33 will not fall easily.

[0031] In a preferred embodiment, a sealing base 8 is fixedly installed on the upper surface of the bottom plate 1, and a heat-conducting strip 9 is fixedly installed on the upper surface of the sealing base 8. The device can seal the packaging bag while venting the packaging bag. The sealing base 8 is installed on the upper surface of the bottom plate 1, and the heat-conducting strip 9 is installed on the sealing base 8. When the heat-conducting strip 9 is energized, heat is generated to seal the packaging bag, which is convenient for use.

[0032] In actual use, the device can not only press out the air inside the packaging bag, but also seal the packaging bag so as to seal the product inside the packaging bag and reduce the volume. For easy operation, a pushing mechanism 10 is installed on the support frame 2, and the pushing mechanism 10 includes a pushing block 101, a bending plate 102 and a sealing top seat 103. A circular groove 11 is provided on the upper surface of the bottom plate 1, and a spring 12 is fixedly installed inside the circular groove 11. One end of the spring 12 is fixedly connected to a round rod 13, and one end of the round rod 13 is connected to the sealing top seat 103. The bottom of the sealing top seat 103 is fixedly installed with a heat-conducting strip 9 of the same specification as that on the sealing base 8. The pushing block 101 is fixedly installed at the bottom of the pressing block 33. There are two pushing blocks 101, which are respectively arranged at the left and right ends of the bottom of the pressing block 33. The pushing block 101 corresponds to the position of the sealing top seat 103. The upper surface of the extrusion plate 312 is rotatably connected to the bending plate 102, and one end of the bending plate 102 is rotatably connected to the bottom of the pressing block 33.

[0033] During operation, the squeezing plate 312 moves downward, pulling the pressing block 33 downward. At this time, the pressing block 33 squeezes the driving plate 6 to move the driving plate 6 connected to the elastic frame 7. At this time, the pressing block 33 continues to move downward under the action of its own weight, and drives the pushing block 101 to move downward. The sealing top seat 103 is squeezed by the pushing block 101 to move the sealing top seat 103 downward, so that the sealing top seat 103 is in contact with the sealing base 8. At the same time, the heat-conducting strips 9 in the sealing top seat 103 are energized to heat them, and the packaging bag is hot-melt sealed by the two heat-conducting strips 9, which is convenient for operation.

[0034] Specifically, the working process or working principle of a packaging machine pressure plate is as follows: the current method of compressing product packaging is to put a packaging bag on the outside of the product. In order to reduce the volume, the pressure plate will be controlled to press the packaging bag to press out the air inside the packaging bag, thereby compressing the product and reducing the volume.

[0035] Although the above method can compress the product and reduce its volume, in actual operation, the packaging bag is squeezed by the pressing plate, but the product is placed inside the packaging bag and has a certain thickness. This causes the upper and lower inner walls of the packaging bag to be unable to fit together, and air will remain inside and cannot be discharged, which will affect the processing effect of the product. Therefore, this device is designed to solve this problem.

[0036] To exhaust the packaging bag using the device, first connect the external power supply, place the product inside the packaging bag, and place the packaging bag on the upper surface of the bottom plate 1, place the port of the packaging bag on the sealing base 8, and then open the cylinder 31, and push the extrusion plate 312 downward through the telescopic end of the cylinder 31. Since the pressing block 33 is slidably connected to the connecting rod 311, the extrusion plate 312 and the pressing block 33 move independently, not together. When the extrusion plate 312 continues to move downward, the bending plate 102 will be straightened, and the pressing block 33 will be driven to move downward.

[0037] As the squeezing plate 312 continues to move downward until it squeezes the packaging bag and presses out the air inside the packaging bag, before the squeezing plate 312 contacts the product, the rolling wheel 32 will first contact the outside of the product. As the squeezing plate 312 continues to move downward, the rolling wheel 32 will be controlled to rotate, so that the bottom of the squeezing plate 312 and the rolling wheel 32 will both contact the outside of the product. The squeezing plate 312 continues to move downward, and the pressing block 33 moves downward, which pushes the connecting rod 311 to rotate and pushes the moving block 322 to move, so that the rolling wheel 32 rolls on the outside of the product. When the rolling wheel 32 is removed from the product, the rolling wheel 32 will rotate downward under the action of its own weight, so that the rolling wheel 32 continues to roll on the packaging bag, thereby improving the exhaust effect on the inside of the packaging bag.

[0038] After squeezing the product, the squeezing plate 312 will continue to squeeze, and under the pulling of the squeezing plate 312, the pressing block 33 will also move downward. The downward movement of the pressing block 33 will press the driving plate 6 to move. At this time, the driving wheel 34 will rotate, and one of the driving plates 6 on the driving wheel 34 will be driven to disengage from the elastic clip 7. The pressing block 33 will continue to move downward under the action of its own weight, and drive the pushing block 101 to move downward. The sealing top seat 103 is squeezed by the pushing block 101, so that the heat-conducting strip 9 on the sealing top seat 103 is in contact with the heat-conducting strip 9 on the sealing base 8. Both heat-conducting strips 9 are energized, which can heat-melt seal the port of the packaging bag so as to seal the product inside the packaging bag.

[0039] After the processing is completed, the cylinder 31 lifts the extrusion plate 312 to move upward. At this time, the extrusion plate 312 will push the driving plate 6 upward to rotate the driving wheel 34, and the driving plate 6 will push the pressing block 33 to move upward. When the extrusion plate 312 returns to its initial position, one of the driving plates 6 will be snapped into the inside of the elastic clip 7 to position the driving wheel 34, and the pressing block 33 can be supported by the other driving plate 6. At this time, the pressing block 33 is in the initial position, and the sealing top seat 103 will be pushed upward under the action of the spring 12, so that the sealing top seat 103 and the sealing base 8 are separated, so that the packaged product can be removed.

[0040] It should be noted that the cylinder 31 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
