Description

TECHNICAL FIELD

[0001] The utility model relates to laminating machine vacuum cavity sealing technical field more specifically relates to a laminating machine sealing gasket structure. BACKGROUND

[0002] Laminating machine usually includes upper box, lower pressing frame and sealing gasket, upper box and lower pressing frame are fastened together, and form vacuum cavity in its inside, sealing gasket is pressed together between upper box and lower pressing frame, and is used for the sealing of vacuum cavity.

[0003] However, the existing sealing gasket is thin and cannot make water line groove, and the two sealing surfaces matched with it are all planes, usually positioning is difficult, positioning precision is not high etc.

[0004] Therefore, providing a laminating machine sealing gasket structure is the urgent problem of the person skilled in the art. UTILITY MODEL CONTENTS

[0005] Therefore, the utility model provides a laminating machine sealing gasket structure, guarantees the sealing property of vacuum cavity.

[0006] In order to realize the above-mentioned purpose, the utility model adopts the following technical scheme:

[0007] A laminating machine sealing gasket structure includes the sealing gasket between laminating machine upper box and lower pressing frame, and the four sides of laminating machine upper box, sealing gasket and lower pressing frame are connected together through bolt.

[0008] Through adopting the above technical scheme, the utility model has the beneficial effects:

[0009] Ensure that the sealing gasket position is fixed, avoid displacement and escape from the sealing surface, improve the sealing property of vacuum cavity.

[0010] Further, the four sides of the sealing gasket have a plurality of positioning holes for the bolt to pass through.

[0011] Further, the sealing gasket includes first high-temperature-resistant flexible layer, tear-resistant mesh cloth layer and second high-temperature-resistant flexible layer connected integrally from top to bottom.

[0012] The beneficial effects produced by the above further technical scheme are that when the edge of the sealing gasket is displaced due to extrusion, the tear-resistant mesh cloth layer provides support for it, and provides the force that it is not extruded by the fixed edge, to ensure that the gasket is not extruded.

[0013] Further, the sealing gasket body has a plurality of air holes.

[0014] The beneficial effect of adopting the above-mentioned further technical solution is that it ensures that the flow of gas is not disturbed during the vacuum and inflation process. Attached Figure Description

[0015] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0017] Fig. 2 The attached figure is a partial structural schematic diagram of a laminator sealing gasket structure provided by this utility model. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figs. 1-2 As shown in the figure, this utility model discloses a sealing gasket structure for a laminator, including a sealing gasket 1 located between the upper chamber and the lower pressure frame of the laminator. The upper chamber, the perimeter of the sealing gasket 1, and the lower pressure frame are connected together by bolts. This utility model ensures that the sealing gasket 1 is fixed in position, preventing displacement and detachment from the sealing surface, thus improving the sealing performance of the vacuum chamber.

[0020] Specifically, the sealing gasket 1 has multiple positioning holes 11 around its perimeter for bolts to pass through.

[0021] It is understandable that the upper box of the laminator has upper bolt holes corresponding to the positioning holes, and the lower frame has lower bolt holes corresponding to the positioning holes. In this way, the bolts are first screwed into the upper bolt holes, pass through the positioning holes 11, and finally screwed into the lower bolt holes, thereby achieving a tight connection between the upper box of the laminator, the sealing gasket 1, and the lower frame.

[0022] Of course, the upper bolt hole can also be a through hole. In this way, the through hole and the positioning hole 11 are passed through in sequence, and finally screwed and tightened into the lower bolt hole.

[0023] In order to further optimize the technical scheme of the utility model, the sealing gasket 1 includes the first high temperature resistance flexible layer 101, the tear resistance mesh cloth layer 102 and the second high temperature resistance flexible layer 103 connected as a whole from top to bottom, when the edge of the sealing gasket 1 is displaced due to extrusion, the tear resistance mesh cloth layer 102 provides support for it, and by providing the fixed edge with the force that is not extruded, the gasket is guaranteed not to be extruded, and the service life is improved.

[0024] In order to further optimize the technical scheme of the utility model, the sealing gasket 1 main body has a plurality of vent holes 12, which ensure that the gas flowability is not disturbed during the vacuum and inflation processes.

[0025] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same or similar parts between various embodiments can be referred to each other. For the device disclosed by the embodiments, since it corresponds to the method disclosed by the embodiments, the description is relatively simple, and the related parts can be referred to the method part.

[0026] The above description of the disclosed embodiments enables those skilled in the art to implement or use the utility model. Various modifications to the embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
