TECHNICAL FIELD

[0001] The present application relates to the technical field of tea packaging opening device, in particular to a pressing type clamp cutter device for opening tea packaging bag. BACKGROUND

[0002] The tea on the market is basically sealed packaging, which needs to be opened before use. In the use of packaging bags, the packaging bags are usually made of multiple materials, and some materials have high toughness and cannot be easily opened without tools. Therefore, packaging bag opening devices such as scissors are needed.

[0003] Scissors are a tool that people use more easily in daily life, but during use, the fingers need to be inserted into the handle, which is uncomfortable for people with large hands. By setting a pressing type opening device, this shortcoming can be avoided. However, the movable connection of the pressing type opening device is prone to rust, which makes the rotation not smooth enough. The current pressing type opening device does not have a self-lubricating mechanism. SUMMARY

[0004] In order to overcome the shortcomings of the prior art, the present application provides a pressing type clamp cutter device for opening tea packaging bag, which is provided with a self-lubricating mechanism. When the rotation of the pressing piece, i.e. the cutting shaft, is not smooth enough, the driving rod can be pulled to lubricate the connection between the cutting shaft and the upper and lower pieces of the cutter.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a press-type clamping cutter device for opening tea packaging bags, comprising a lower cutter blade, an upper cutter blade disposed above the lower cutter blade, one end of the lower cutter blade and the upper cutter blade being fixed together, and a gap existing between the other ends, with a scissor shaft passing through them vertically for rotatably connecting the upper cutter blade, a self-lubricating mechanism for lubricating the scissor shaft being installed on the outer surface of the side of the lower cutter blade near the scissor shaft and facing the upper cutter blade, the distance between the self-lubricating mechanism and the upper cutter blade being greater than the distance that the upper cutter blade can press down, and including a lubrication box fixed to the outer surface of the lower cutter blade, the lubrication box being hollow and configured for lubrication. The lubrication chamber includes: a cavity; a first lubricating sponge and a second lubricating sponge, respectively fixedly bonded to the upper and lower walls of the lubrication chamber, both filled with lubricating oil; a movable block disposed between the first and second lubricating sponges, with a gap between the movable block and the first lubricating sponge; a pressing plate disposed below the movable block, with a gap between the pressing plate and the second lubricating sponge; an elastic support connecting the movable block and the pressing plate; a first lubricating pipe extending upward through the wall of the lubrication chamber into the first lubricating sponge; and a second lubricating pipe extending downward through the wall of the lubrication chamber into the second lubricating sponge.

[0006] As a preferred embodiment of the present invention, the elastic support includes a support plate fixedly disposed on the top wall of the extrusion plate, a telescopic rod mounted on the support plate, the top of the telescopic rod being mounted on the movable block, and a spring fixedly connected between the movable block and the support plate being sleeved on the outside of the telescopic rod.

[0007] As a preferred embodiment of the present invention, two sliders are symmetrically fixed on the outer walls of both sides of the movable block, and grooves adapted to the shape and size of the sliders are provided on the two side walls of the lubrication box. The sliders are slidably disposed in the grooves.

[0008] As a preferred embodiment of the present invention, a strip-shaped movable groove is provided on the outer surface of the front side of the lubrication box, corresponding to the movable block. A drive rod is movably disposed in the movable groove. One end of the drive rod is fixed to the outer surface of the movable block, and the other end is spherical and located outside the lubrication box.

[0009] As a preferred embodiment of the present invention, the shear shaft passes through a rotating hole opened at a corresponding position on the lower cutter blade, and the second lubrication tube is located above the rotating hole.

[0010] As a preferred embodiment of the present invention, a shaped groove is provided on one side of the upper end of the shear shaft, which passes through a corresponding perforation on the shear shaft, and the first lubrication tube is located directly below the perforation.

[0012] As a preferred technical scheme of the present application, the press block is welded on the upper surface of the side of the press plate close to the shearing shaft, and the recess is arranged on the upper surface of the cutter upper plate corresponding to the press block.

[0013] Compared with the prior art, the present application has the following beneficial effects:

[0014] When the connection between the shearing shaft and the cutter lower plate needs to be lubricated, the extrusion plate is compressed to make the lubricating oil enter the connection between the shearing shaft and the cutter lower plate through the second lubricating pipe by sliding the driving rod downward. Similarly, when the connection between the shearing shaft and the cutter upper plate needs to be lubricated, the device is turned over, and the driving rod is pulled downward to make the moving block extrude the first lubricating sponge, so that the lubricating oil enters the connection between the shearing shaft and the cutter upper plate through the first lubricating pipe. When the rotation of the press plate, i.e. the shearing shaft, is not smooth enough, the driving rod is pulled to lubricate the connections between the shearing shaft and the cutter upper plate and the cutter lower plate.

[0030] Embodiment four

[0031] The embodiment is an improvement on the embodiment 1, and specific reference can be made to the embodiment 1. Figure 1 、 Figure 4 The pressing piece 3 is connected in rotation in the special-shaped slot 6, the anti-skid convex 4 is arranged on the end of the pressing piece 3 which is away from the shearing shaft 5, the pressing block 7 is welded on the upper surface of the side of the pressing piece 3 which is close to the shearing shaft 5, and the groove 701 is formed in the upper surface of the cutter upper piece 2 and corresponds to the pressing block 7.

[0032] In the embodiment, when the cutter device is used, if the tea bag needs to be opened, the pressing piece 3 is first rotated, the pressing piece 3 is rotated to the opposite direction in the special-shaped slot 6 through the side of the pressing piece 3 which is connected with the shearing shaft 5, then the finger is placed on the anti-skid convex 4 of the pressing piece 3, the pressing piece 3 is pressed down, the pressing block 7 is in contact with the groove 701 formed in the cutter upper piece 2, the cutter upper piece 2 is driven to move downward outside the shearing shaft 5 through the pressing block 7, the packaging bag is placed between the cutter upper piece 2 and the cutter lower piece 1, and the opening can be performed, which is very convenient. The second lubricating pipe 14 is arranged above the rotating hole 101, when the connection position of the shearing shaft 5 and the cutter lower piece 1 needs to be lubricated, the extrusion plate 12 is compressed to make the second lubricating sponge 11 through the downward sliding of the driving rod 19, so that the lubricating oil enters the connection position of the shearing shaft 5 and the cutter lower piece 1 through the second lubricating pipe 14. Similarly, the first lubricating pipe 15 is arranged directly below the perforation 201, when the connection position of the shearing shaft 5 and the cutter upper piece 2 needs to be lubricated, the device is turned over, and the moving block 9 extrudes the first lubricating sponge 10 through the downward pulling of the driving rod 19, so that the lubricating oil enters the connection position of the shearing shaft 5 and the cutter upper piece 2 through the first lubricating pipe 15.

[0033] Working principle: When using this cutter device, to open a tea bag, first rotate the pressing plate 3 to the opposite direction. Then, place your finger on the anti-slip protrusion 4 of the pressing plate 3 and press down on the pressing plate 3. This makes the pressing block 7 contact the groove 701 in the upper cutter plate 2. The pressing block 7 then moves the upper cutter plate 2 downward, placing the packaging bag between the blades of the upper cutter plate 2 and the lower cutter plate 1, making it easy to open. When the rotation of the pressing plate 3 is not smooth enough, the self-lubrication mechanism can be used for lubrication. When using the self-lubrication mechanism, to lubricate the connection between the shear shaft 5 and the lower cutter plate 1, slide the drive rod 19 downward. The drive rod 19 moves the moving block 9 downward, compressing the spring 18 and simultaneously moving the extrusion plate 12 downward. This causes the slider 13 to move within the groove 1301, allowing the extrusion plate 12 to compress the second lubricating sponge 11. This causes the lubricating oil in the second lubricating sponge 11 to overflow and enter the connection between the shear shaft 5 and the lower cutter blade 1 through the second lubrication tube 14, thus lubricating the rotating hole 101. Similarly, when it is necessary to lubricate the connection between the shear shaft 5 and the upper cutter blade 2, simply turn the device upside down and pull the drive rod 19 downward. The drive rod 19 drives the moving block 9 downward, while the slider 13 moves within the slide groove 1301. At this time, the moving block 9 stretches the spring 18, and the moving block 9 itself squeezes the first lubricating sponge 10, causing the lubricating oil in the second lubricating sponge 11 to overflow. The lubricating oil enters the connection between the shear shaft 5 and the upper cutter blade 2 through the first lubrication tube 15, thus lubricating the perforation 201. Through the self-lubrication mechanism, when the rotation of the pressing plate 3, i.e., the shear shaft 5, is not smooth enough, the drive rod 19 can be pulled to lubricate the connection between the shear shaft 5 and the upper cutter blade 2 and the lower cutter blade 1.
