[0051] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0052] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships described in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0053] Combine Figures 1 to 4 As shown, one embodiment of the present invention provides a mold opening adjustment mechanism, including a lifting structure 1, a clamping ring structure 2 and a mounting structure 3, the clamping ring structure 2 includes a locking part 201 and an adjusting part 202, the locking part 201 is connected to the output end of the lifting structure 1, and the adjusting part 202 is connected to the mounting structure 3.

[0054] Specifically, the locking portion 201 on the clamping ring structure 2 is locked and fixed with the output end of the lifting structure 1. The lifting structure 1 is used to be fixed on an external fixed plate or other horizontal fixing parts. The lifting structure 1 is connected to the external lifting module through the mounting structure 3. The mounting structure 3 is adjustably mounted on the adjusting portion 202, thereby adjusting the mold opening height to ensure that the pulp molding equipment meets the mold closing requirements when the maximum stroke of the cylinder is fixed, and ensure that after the mold is opened, the distance between the upper and lower molds is more than twice the height of a single mold cavity of the mold. A locking portion 201 is also provided on the mounting structure 3 to adjust its position on the adjusting portion 202 when the locking portion 201 is not locked.

[0055] It should be noted that when the height of the external lifting module is adjusted, it is only necessary to separate the clamping ring structure 2 from the mounting structure 3. At this time, the lifting structure 1 and the clamping ring structure 2 are still fixedly connected. The lifting structure 1 then drives the clamping ring structure 2 to move up and down to adjust the required clamping position. After adjustment, the mounting structure 3 and the clamping ring structure 2 are fixed to complete the overall adjustment. The overall structure is simple and easy to operate.

[0056] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features.

[0059] The movable clamping member a 20112 and the movable clamping member b 20113 are both symmetrically provided with fastening holes 2012, and the central axes of the fastening holes 2012 on the movable clamping member a 20112 and the fastening holes 2012 on the clamping member b 20113 coincide with each other;

[0060] The locking member is installed on the fastening hole 2012 of the clamping member a 20112 and extends to the outside of the fastening hole 2012 on the clamping member b 20113;

[0061] The limiting member 2014 is fixedly sleeved on the outer surface of the movable member 2011 .

[0062] Specifically, the first locking member 2013 is passed through the fastening hole 2012 and locked. At this time, the first locking member 2013 locks the clamping member a 20112 and the clamping member b 20113. The clamping member a 20112 and the clamping member b 20113 generate a clamping force to strengthen and fix the output end of the lifting rod.

[0063] It should be noted that the clamping member a 20112 and the clamping member b 20113 can conveniently adjust the movable member 2011 and the output end of the lifting structure 1 through the first locking member 2013. After adjusting the movable member 2011, the first locking member 2013 is locked to fix it, thereby quickly completing the adjustment of the height of the external lifting module.

[0064] Furthermore, the limiting member 2014 is used to limit the mounting structure 3 .

The connecting member 2021 is mounted on one side of the movable member 2011 . The plurality of first annular members 2022 are mounted on the connecting member 2021 in a regular array.

[0067] An annular groove 2023 is formed between each two first annular members 2022 that are close to each other, and through holes that communicate with each other are formed on the movable member 2011 and the connecting member 2021;

[0068] The mounting structure 3 includes a fixing seat a 301, a fixing seat b 302, a fastener 303 and a second locking member 304;

[0069] The tops of the fixing base a 301 and the fixing base b 302 are both provided with fasteners 303;

[0070] The second locking member 304 is installed on the fastener 303 to fix the fixing base a 301 and the fixing base b 302;

[0072] Specifically, the fixing base a 301 and the fixing base b 302 are fixedly connected to the external lifting module through the mounting holes 4 on the fixing base a 301 and the fixing base b 302. When adjusting the height, it is only necessary to remove the fixing base b 302. After the adjustment is completed, the fixing base a 301 and the fixing base b 302 are fixed to the adjustment part 202 through the second locking member 304 and the fastener 303. The arc block 305 and the annular groove 2023 are locked to complete the fixation of the fixing base a 301 and the fixing base b 302 to the adjustment part 202.

[0073] It should be noted that when it is necessary to debug the mold opening height, the mold is first closed and the fixed seat b 302 is removed. Then, the output end of the lifting structure 1 is adjusted. When it is necessary to increase the mold opening distance, the adjusting part 202 is lowered through the output end of the lifting structure 1. After lowering, the adjusting part 202 extends into the cavity reserved for the external lifting module. When it is necessary to reduce the mold closing distance, the adjusting part 202 is raised through the output end of the lifting structure 1. Finally, the fixed seat b 302 is installed, and the fixed seat a 301 and the fixed seat b 302 are fixed to the adjusting part 202 through the second locking member 304, thereby completing the debugging.

[0074] Furthermore, in the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, a first feature being "above," "above," or "above" a second feature may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. A first feature being "below," "below," or "below" a second feature may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0075] In one embodiment, a plurality of mounting holes 4 are provided on both the fixing base a 301 and the fixing base b 302 , and the number of the mounting holes 4 on the fixing base b 302 is less than that on the fixing base a 301 .

[0076] Specifically, the fixing base a 301 and the fixing base b 302 are fixedly connected to the lifting plate 5 through the mounting holes 4 on the fixing base a 301. When adjusting the height, only the fixing base b 302 needs to be removed, because the number of mounting holes 4 on the fixing base b 302 is less than that on the fixing base a 301, thereby facilitating disassembly and fixation.

[0077] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0078] In one embodiment, a lifting plate 5 is further included, and the lifting plate 5 is installed at the bottom of the fixing seat a 301 and the fixing seat b 302;

[0079] The bottom of the lifting plate 5 is equipped with a mold upper mold 6;

[0080] A lower mold 7 is provided below the upper mold 6 , and a fixed template 8 is installed at the bottom of the lower mold 7 .

[0081] Specifically, a reserved cavity is provided on the lifting plate 5 to fit the adjustment portion 202, so that there is no influence during adjustment. During adjustment, the lifting plate 5 does not need to be moved. Only the output end of the lifting structure 1 needs to be adjusted. After adjustment, the fixing seat a 301 and the fixing seat b 302 are locked to the adjustment portion 202 using the second locking member 304 and the fastener 303.

[0082] It should be noted that the upper mold 6 under the lifting plate 5 is detachable, so that molds of different heights or sizes can be replaced.

[0083] In one embodiment, the movable member 2011 includes a locked state and a movable state. When the movable member 2011 is in the locked state, the first locking member 2013 is locked. After the first locking member 2013 is locked, the movable clamping member a20112 and the movable clamping member b20113 are close to each other. At this time, the movable member 2011 is fixedly connected to the output end of the lifting structure 1. When the movable member 2011 is in the movable state, the first locking member 2013 is not locked, the movable clamping member a20112 and the movable clamping member b20113 are in a normal state, and at this time, the movable member 2011 is movably connected to the output end of the lifting structure 1.

[0084] The fastener 303 includes a fastened state and an active state. When the fastener 303 is in the fastened state, the second locking member 304 is locked, and the arc blocks 305 on the two fasteners 303 form an annular buckle, which is located in the annular groove 2023. At this time, the two fasteners 303 are fixedly connected to the connecting member 2021 through the annular buckle and the annular groove 2023. When the fastener 303 is in the active state, the second locking member 304 is not locked. At this time, the two fasteners 303 are detachably installed on the connecting member 2021.

[0085] Specifically, a snap ring is continuously formed by the first annular member 2022 and the adjusting portion 202. When the output end of the lifting rod is threadedly connected to the through holes on the movable member 2011 and the connecting member 2021, the first locking member 2013 is passed through the fastening hole 2012 and locked. At this time, the first locking member 2013 locks the clamping member a 20112 and the clamping member b 20113. The clamping member a 20112 and the clamping member b20113 generate a clamping force to strengthen the fixation of the output end of the lifting rod. It is fixedly connected to the lifting plate 5 through the mounting holes 4 on the fixing seat a301 and the fixing seat b 302. When adjusting the height, it is only necessary to remove the fixing seat b 302. After the adjustment is completed, the fixing seat a 301 and the fixing seat b 302 are fixed to the adjusting portion 202 by the second locking member 304 and the fastener 303, and the fixing seat a 301 and the fixing seat b 302 are locked with the arc block 305 and the annular groove 2023 to complete the fixing seat a 301 and the fixing seat b 302 are fixed to the adjustment part 202.

[0086] In one embodiment, the side of the connecting member 2021 away from the movable member 2011 is threadedly connected to an extension rod 9 , and a plurality of second annular members 901 are threadedly connected to the extension rod 9 .

[0087] Specifically, the length of the adjusting member can be extended by the extension rod 9 so that it can adapt to molds of different thicknesses, and the second annular member 901 is threadedly connected to the extension rod 9. The second annular member 901 can be adjusted to an appropriate distance as needed to facilitate subsequent adjustments. The extension rod 9 can also be disassembled as needed.

[0088] It should be noted that a threaded portion is provided on the extension rod 9, and its thread is on the outer wall of the threaded portion. An internal thread that matches the threaded portion is provided on the inner wall of the bottom of the through hole of the connecting piece 2021. The extension rod 9 and the connecting piece 2021 are fixed by the cooperation of the external thread and the internal thread, and the top inner wall of the connecting piece 2021 is also provided with a thread, which is convenient for threaded connection with the output end of the lifting structure 1. This is not described in the claims and is described in detail here.

[0089] Furthermore, the several mounting holes 4 on the fixing seat a 301 can be one, two or several, and the number is not limited again. The several mounting holes 4 on the fixing seat b 302 can be one, two or several, but preferably two. If there are too many mounting holes 4 on the fixing seat b 302, it will make the fixing seat b 302 difficult to disassemble, which is explained here.

[0090] Working principle of the present invention:

[0091] The first annular member 2022 and the adjusting portion 202 continuously form a snap ring, and the output end of the lifting rod is threadedly connected to the through holes on the movable member 2011 and the connecting member 2021, and then the first locking member 2013 is passed through the fastening hole 2012 and locked. At this time, the first locking member 2013 locks the clamping member a20112 and the clamping member b 20113, and the clamping member a 20112 and the clamping member b 20113 generate a clamping force to strengthen the fixation of the output end of the lifting rod, and is fixedly connected to the lifting plate 5 through the mounting holes 4 on the fixing seat a 301 and the fixing seat b 302. When adjusting the height, it is only necessary to remove the fixing seat b 302. After the adjustment is completed, the fixing seat a 301 and the fixing seat b 302 are fixed to the adjusting portion 202 by the second locking member 304 and the fastener 303, and the fixing seat a 301 and the fixing seat b are locked by the arc block 305 and the annular groove 2023 to complete the fixing seat a 301 and the fixing seat b 302 is fixed to the adjustment part 202. When it is necessary to debug the mold opening height, the mold is first closed and the fixed seat b 302 is removed. Then, the output end of the lifting structure 1 is adjusted. When it is necessary to increase the mold opening distance, the adjusting part 202 is lowered through the output end of the lifting structure 1. After lowering, the adjusting part 202 extends into the cavity reserved in the lifting plate 5. When it is necessary to reduce the mold closing distance, the adjusting part 202 is raised through the output end of the lifting structure 1. Finally, the fixed seat b 302 is installed, and the fixed seat a 301 and the fixed seat b 302 are fixed to the adjustment part 202 through the second locking member 304, thereby completing the debugging.
