A vent 317 is provided at the bottom left end of the material control shell 31, and the inner wall piston of the vent 317 is connected to a control plug 318.

[0026] Reference Figure 1 - Figure 3The pressing mechanism 3 also includes a slide plate 36, the inner wall of the slide plate 36 is connected to the inner wall piston of the material control shell 31, the outer wall of the slide plate 36 is fitted with the inner wall of the material control shell 31, and the top of the slide plate 36 is fixedly connected to a moving frame 37, which is in the shape of a hollow cylinder. The color of the moving frame 37 is colorless and transparent, and the outer surface of the moving frame 37 is provided with scale lines. The inner wall of the moving frame 37 is slidably connected to a moving plate 38, and the friction between the moving plate 38 and the inner wall of the moving frame 37 is less than the friction between the slide plate 36 and the material control shell 31. Through the comparison of friction, it is ensured that the moving plate 38 can only drive the moving frame 37 and the slide plate 36 to move after it moves to the point where it can no longer move alone. The top of the moving frame 37 is fixedly connected with a pull rope 316, the pull rope 316 passes through the inner wall of the material control shell 31, and the inner wall of the moving frame 37 above the moving plate 38 is slidably connected with an adjustment plate 39, the adjustment plate 39 is in the shape of a ring, and the inner wall of the adjustment plate 39 passes through and is threadedly connected with a threaded rod 310.

[0027] Reference Figure 3 - Figure 5 The top of the material control shell 31 is fixedly connected to the cylinder 311, and the output shaft of the cylinder 311 passes through the inner wall of the material control shell 31 and is fixedly connected to the top of the movable plate 38. The up and down movement of the output shaft of the cylinder 311 drives the movable plate 38 to move up and down. The pressing mechanism 3 also includes a rotating rod 312 and a bevel gear 1 313. The rotating rod 312 passes through and is rotatably connected to the inner wall of the material control shell 31. The left side of the rotating rod 312 is fixedly connected to the bevel gear 2 314, and the bevel gear 1 313 moves to the top position and meshes with the bevel gear 2 314. The right side of the rotating rod 312 is fixedly connected to the knob 315, and the outer wall of the knob 315 is provided with anti-slip grooves. The bevel gear 1 313 is fixedly connected to the top of the threaded rod 310.

[0028] Reference Figure 3 - Figure 5The inner part of the material control shell 31 is provided with a protection component 4, which includes a movable groove 41, which is opened on the inner wall of the material control shell 31, and a movable bar 42 is slidably connected to the inner wall of the movable groove 41. The movable bar 42 is in an L-shape, and the top of the movable bar 42 is elastically connected to the inner wall of the movable groove 41 by a spring 43. One end of the spring 43 is fixedly connected to the top of the movable bar 42, and the other end of the spring 43 is fixedly connected to the inner wall of the movable groove 41. The bottom end of the movable bar 42 is fixedly connected to an insertion bar 44, and the shape of the insertion bar 44 is a shape formed by connecting a cylinder and a hemisphere, and the hemispherical part of the insertion bar 44 is at the lower end of the insertion bar 44. The outer wall of the rotating rod 312 is provided with a socket 45. When the movable bar 42 is in the lowermost position, the length of the area below the movable groove 41 at the left end of the movable bar 42 is consistent with the depth of the socket 45.

[0029] Working principle: During use, when the staff needs to adjust the pressure, first start the cylinder 311. When the output shaft of the cylinder 311 drives the movable plate 38 to move upward, when the movable plate 38 moves to its uppermost position that can be moved, the staff first opens the control plug 318, and then pulls the pull rope 316, so that the pull rope 316 drives the movable frame 37 to move upward.

[0030] When the moving frame 37 moves upward until it contacts the bottom end of the moving bar 42 , the pull rope 316 is continuously pulled, so that the moving frame 37 pushes the moving bar 42 upward during the upward movement, thereby causing the moving bar 42 to drive the insertion bar 44 to move upward, thereby causing the insertion bar 44 to leave the socket 45 .

[0031] When the movable frame 37 moves to the upper surface and contacts the inner wall of the material control shell 31, the movable plate 38 just contacts the inner wall of the bottom end of the material control shell 31. At this time, the staff fixes the pull rope 316 and turns the knob 315, so that the knob 315 can drive the rotating rod 312 to rotate, thereby causing the rotating rod 312 to drive the bevel gear 2 314 to rotate, thereby driving the bevel gear 1 313 to rotate, thereby causing the bevel gear 1 313 to drive the threaded rod 310 to rotate, thereby causing the adjustment plate 39 to move up and down under the drive of the threaded rod 310. Since the material control shell 31 is colorless and transparent, the staff can observe the moving position of the adjustment plate 39 at this time.

[0032] When the movable frame 37 is not moved to the appropriate position, the inserting bar 44 cannot completely leave the socket 45, and the rotating rod 312 cannot rotate due to the limiting effect of the inserting bar 44. Therefore, when the staff can turn the knob 315, it can be ensured that the bevel gear 1 313 and the bevel gear 2 314 maintain a meshing relationship.

[0033] Since the movable plate 38 contacts the inner wall of the bottom end of the material controlling shell 31 , the movable plate 38 will not affect the position adjustment of the adjustment plate 39 during the process of moving the position of the adjustment plate 39 .

[0034] When the adjustment is completed, the staff inserts the control plug 318 and loosens the pull rope 316. At this time, the staff can use the equipment normally. When using the equipment normally, the staff controls the cylinder 311 so that the output shaft of the cylinder 311 drives the slide 36 and the moving plate 38 to move up and down. In the process of the moving plate 38 moving upward, the moving plate 38 first moves upward alone with the output shaft of the cylinder 311. When it moves to contact the bottom end of the adjustment plate 39, the moving plate 38 drives the adjustment plate 39 to move upward together, and applies an upward force to the threaded rod 310 through the adjustment plate 39, so that the threaded rod 310 drives the moving frame 37 and the slide 36 to move upward.

[0035] After moving to the highest point, the movable plate 38 moves downward under the control of the output shaft of the cylinder 311, so that the movable plate 38 moves downward first, and when it moves to contact the top of the slide plate 36, it drives the slide plate 36 to move downward.

[0036] Since the heights of the adjustment plate 39 are different, and the total distance moved by the movable plate 38 is the same, when the adjustment plate 39 is at different heights, the distances moved by the movable frame 37 are different, thereby driving the movable plate 38 to move different distances.

[0037] As the slide 36 moves upward, the space at the bottom of the material control shell 31 increases, thereby reducing the air pressure at the bottom of the material control shell 31 at the slide 36. Because the one-way valve 35 can only flow from left to right, the gas on the right side of the discharge pipe 33 cannot enter the material control shell 31. Only the adhesive inside the storage barrel 1 can enter the material control shell 31 through the feed pipe 32.

[0038] When the slide plate 36 moves downward, since the one-way valve 1 34 can only flow from bottom to top, the adhesive cannot flow out through the feed pipe 32 and can only flow out through the discharge pipe 33.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
