Abstract
Description
Technical Field
[0001] This invention relates to the field of coating technology, specifically to a mechanism for adjusting the relative position of the lips of a coating die. Background Technology
[0002] The coating die head is an essential component in the operation of existing coating machines. Currently, the coating die head mainly consists of an upper die, a middle die, and a lower die. The flow of sauce between the upper, middle, and lower dies is maintained by the gaskets and lip openings between them.
[0003] In the use of existing mold heads, it is sometimes necessary to offset the lips. The lip adjustment parts currently used on the market are back fixing blocks. When using this part to achieve lip offset, the machine needs to be stopped, the back fixing block removed, a fixed shim inserted, and then reassembled to achieve lip offset.
[0004] However, existing die heads are limited by the standard specifications of the gaskets when adjusting the lip, and can only adjust the lip quantitative value. They cannot be adjusted online in real time, and cannot perfectly match the actual needs. If there are many layers in the die head, the mechanism needs to be doubled, which occupies more space. In addition, there are fatal defects such as uneven thickness of each gasket, inability to read in real time, inability to self-check whether the gasket is used correctly, and inability to guarantee accuracy. Summary of the Invention
[0005] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.
[0006] Therefore, the purpose of this invention is to provide a mechanism for adjusting the relative position of the lips of a coating die, replacing the traditional method of adjusting the lip of the die, and avoiding the problem that when adjusting the misalignment of the lip of the die, only a fixed value can be adjusted and it is not possible to adjust it online in real time.
[0007] To address the aforementioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:
[0008] A mechanism for adjusting the relative position of the lips of a coating die head, comprising:
[0009] plate body;
[0010] A fixing mechanism is installed on the side wall of the plate body for fixing the plate body to the middle mold;
[0011] An adjustment mechanism, installed on the side wall of the plate, is used to pull the upper mold backward and push the lower mold forward during operation;
[0012] A measuring mechanism, installed on the side wall of the plate, is used to measure the distance moved when the upper mold is pushed forward by the adjusting mechanism and then the lower mold is pushed forward.
[0013] As a preferred embodiment of the mechanism for adjusting the relative position of the lips of the coating die head according to the present invention, the fixing mechanism includes a fixing hole formed in the plate body and a fixing screw that passes through the fixing hole and connects to the threaded hole of the side wall of the middle die.
[0014] As a preferred embodiment of the mechanism for adjusting the relative position of the lips of the coating die head according to the present invention, the upper and lower ends of the side wall of the plate are respectively provided with a first connecting hole and a second connecting hole.
[0015] The adjustment mechanism includes a pull screw that passes through the first connecting hole and connects to the threaded hole on the side wall of the upper mold, and a push screw that passes through the second connecting hole and connects to the threaded hole on the side wall of the lower mold.
[0016] As a preferred embodiment of the mechanism for adjusting the relative position of the lips of the coating die head according to the present invention, the sidewall of the plate body is provided with mounting holes below the first connecting hole and the second connecting hole respectively;
[0017] The measuring mechanism includes a dial indicator installed in two of the mounting holes, with one end of the dial indicator having a probe that passes through the mounting hole and contacts the sidewalls of the upper and lower molds, respectively.
[0018] As a preferred embodiment of the mechanism for adjusting the relative position of the lip of the coating die head according to the present invention, the plate body has notches on both the upper and lower sides of the side adjacent to the upper and lower dies, which are connected to the first connecting hole, the second connecting hole and the mounting hole.
[0019] As a preferred embodiment of the mechanism for adjusting the relative position of the lips of the coating die head according to the present invention, the plate body is an integrally formed structure.
[0020] Compared with the prior art, the beneficial effects of this invention are that the mechanism for adjusting the relative position of the coating die lip is to fix the plate on the middle die through the fixing mechanism, and to pull the upper die backward and push the lower die forward through the working of the adjustment mechanism, thereby pulling the upper film and the lower die and changing the size of their lip. The displacement of the upper and lower dies is measured by the measuring mechanism, which facilitates the calibration of the lip adjustment value. This replaces the traditional die lip adjustment method and avoids the problem that when adjusting the lip misalignment of the die, only a fixed value can be adjusted and online real-time adjustment is not possible.

[0029] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0030] This invention provides a mechanism for adjusting the relative position of the lips of a coating die, replacing the traditional method of adjusting the lip of the die, and avoiding the problem that when adjusting the misalignment of the lip of the die, only a fixed value can be adjusted and online in real time is not possible.
[0031] Figures 1-4 The diagram shown is a structural schematic of a mechanism for adjusting the relative position of the lips of a coating die head according to the present invention. Please refer to [link / reference]. Figures 1-4 This paper provides a detailed description of the mechanism used to adjust the relative position of the lips of the coating die.
[0032] In some embodiments, the present invention discloses a mechanism for adjusting the relative position of the lips of a coating die, the main body of which includes a plate 100, a fixing mechanism 200, an adjusting mechanism 300, and a measuring mechanism 400.
[0033] The plate 100 is used to concentrate the misalignment mechanism of the upper mold 510, the middle mold 520, and the lower mold 530 on the same component, thereby reducing the area occupied by the back of the entire mold head.
[0034] In this embodiment, the plate 100 is an integrally molded structure, which is used to increase the overall toughness of the plate 100, thereby maintaining the stability of the entire mechanism after long-term and repeated use, and thus reducing the error caused by subsequent measurements.
[0035] In this embodiment, the upper and lower ends of the side wall of the plate 100 are respectively provided with a first connecting hole 110 and a second connecting hole 120, which are used to facilitate the connection of the pull screw and the push screw 320 through the threaded holes of the side wall of the plate 100 with the upper mold 510 and the lower mold 530.
[0036] In this embodiment, the side wall of the plate 100 is provided with mounting holes 130 below the first connecting hole 110 and the second connecting hole 120, respectively, for engaging the fixing rod of the dial indicator, thereby fixing and installing the dial indicator.
[0037] In this embodiment, the plate 100 has notches 140 on both the top and bottom of one side adjacent to the upper mold 510 and the lower mold 530, which are connected to the first connecting hole 110, the second connecting hole 120 and the mounting hole 130. This is to facilitate the extension of the dial indicator probe to contact the side wall of the upper mold 510 and the lower mold 530, and at the same time, it reserves space for the upper mold 510 to be pulled back and flipped, as well as space for the extension and retraction of the dial indicator probe.
[0038] The fixing mechanism 200 is used to fix the plate 100 to the mold head. Specifically, the fixing mechanism 200 is installed on the side wall of the plate 100 and is used to fix the plate 100 to the middle mold 520.
[0039] In this embodiment, the fixing mechanism 200 includes a fixing hole 210 formed in the plate 100 and a fixing screw 220 that passes through the fixing hole 210 and connects to the threaded hole on the side wall of the intermediate mold 520, for fixing the plate 100 to the intermediate mold 520 by the cooperation of the fixing screw 220 and the fixing hole 210.
[0040] The adjustment mechanism 300 is installed on the side wall of the plate 100. During operation, it pulls the upper mold 510 backward and pushes the lower mold 530 forward. Due to the connection of the hinge on the back of the upper mold 510 and the lower mold 530, the upper mold 510 and the lower mold 530 are driven to rotate slightly, thereby indirectly adjusting the size of their lips.
[0041] In this embodiment, the adjustment mechanism 300 includes a pull screw 310 that passes through the first connecting hole 110 and is connected to the threaded hole on the side wall of the upper mold 510, and a push screw 320 that passes through the second connecting hole 120 and is connected to the threaded hole on the side wall of the lower mold 530. By tightening the pull screw 310, the upper mold 510 is pulled, thereby causing the upper mold 510 to flip. By tightening the push screw 320, the end of the lower mold 530 away from the back is tilted up, thereby performing offset adjustment.
[0042] The measuring mechanism 400 is installed on the side wall of the plate 100 and is used to measure the distance that the upper mold 510 moves when the adjusting mechanism 300 pushes the lower mold 530 forward, so as to facilitate the calibration and adjustment of the values.
[0043] In this embodiment, the measuring mechanism 400 includes a dial indicator installed in two mounting holes 130. One end of the dial indicator with a probe passes through the mounting hole 130 and contacts the sidewalls of the upper mold 510 and the lower mold 530 respectively. When the upper mold 510 is pulled back and flipped, the probe of the dial indicator is squeezed, and the probe moves to measure the amount of adjustment of the upper mold 510 by pulling it back. Similarly, when the lower mold 530 is pushed forward, the probe of the dial indicator gradually moves away from the sidewall of the lower mold 530, and the probe extends outward. The amount of adjustment of the lower mold 530 is measured by the movement of the probe, which facilitates real-time connection to the adjustment parameters.
[0044] In this embodiment, the specific usage process is as follows: When it is necessary to adjust the misalignment of the mold head, firstly, by tightening the pull screw 310, under the fixing action of the plate 100, the upper mold 510 is pulled back, thereby changing the size of the lip between the upper mold 510 and the middle mold 520. By tightening the push screw 320, the lower mold 530 is tilted away from the back end, thereby changing the size of the lip between the lower mold 530 and the middle mold 520, thus adjusting the misalignment. At the same time, the adjustment parameters are measured by a dial indicator, which facilitates the control of the adjustment accuracy. The entire mechanism can be adjusted in real time without disassembly, and it has the reason to read the data. After each disassembly and maintenance, it can be accurately reset according to the data, reducing errors.
[0045] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
