Description

Technical Field

[0001] The invention relates to a rubber baffle for a film coating machine, belonging to the technical field of roller type film coating equipment. Background Art

[0002] The coating machine mainly transfers the resin to the workpiece surface by the relative rotation between two coating rollers. It is usually necessary to install a glue blocking device on both sides of the two coating rollers. This device can not only prevent the resin from leaking from both sides, but also adjust and control the width of the resin film.

[0003] The traditional glue baffle structure generally adopts an "h"-shaped relative contact type. Since the contact tightness cannot be controlled, glue leakage often occurs during production, which greatly affects the appearance of the resin film and makes it difficult to control the width of the resin film. In addition, the use of traditional metal springs to control the gap between the glue baffles makes the installation operation complicated and difficult. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a glue baffle plate for a coating machine that can effectively prevent the glue liquid from penetrating into the glue casting groove from the gap between the glue baffle plate assembly and the gap between the glue baffle plate and the roller, thereby solving the problems of glue seepage due to roller rotation and glue seepage from the glue baffle plate itself.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A glue baffle for a coating machine, comprising two groups of left and right oppositely arranged component fixing plates, the outer side of the component fixing plates are fixedly provided with a first component, a second component and a third component which are contacted and spliced ​​into a whole in pairs, one side of the first component and the second component are respectively provided as an upper roller contact surface and a lower roller contact surface, a gap is left between the first component, the second component and the third component, and the gap is filled with felt, and the two oppositely arranged third components are respectively connected to the two ends of the bottom plate of the glue groove on one side away from the first component and the second component, wherein the height of the gap is 1-2 mm.

[0007] A protrusion extends from the upper end of the component fixing plate, and two ends of the device position fixing rod pass through the two protrusions respectively.

[0008] The first component is provided with a first bolt hole, the second component is provided with a second bolt hole, and the third component is provided with a third bolt hole. The fixing bolts are respectively passed through the first bolt hole, the second bolt hole and the third bolt hole and then fixed on the component fixing plate.

[0009] A vertical groove is provided on one side of the third component that contacts the first and second components, and an upper protrusion and a lower protrusion that cooperate with the vertical groove are respectively provided on one side of the first and second components that contact the third component.

[0010] An oblique protrusion is arranged on one side of the first component that contacts the second component, and an oblique groove that matches the oblique protrusion is arranged on one side of the second component that contacts the first component.

[0011] The material of the first component, the second component and the third component includes polytetrafluoroethylene.

[0012] The beneficial effects of the present invention are as follows: the present invention provides a glue baffle plate for a coating machine, which changes the traditional installation method of a metal spring, and prevents the glue leakage between the glue baffle plate components through the concave and convex plug-in clamping method of the contact surface. At the same time, the installation and operation are simple, and the production efficiency can be improved; a certain gap is left between the plates of the plug-in glue baffle plate, and the sheet-type felt is filled to play the role of a spring and prevent glue leakage; the width of the glue groove can be adjusted by installing a fixing rod to meet the requirements of coating different widths of glue films.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the protection scope of the present invention.

[0021] like Figure 1 , Figure 2 and Figure 6 As shown, the present invention discloses a glue baffle plate for a coating machine, comprising two groups of left and right component fixing plates 4 arranged opposite to each other, and the outer side of the component fixing plate 4 is fixedly provided with a first component 1, a second component 2 and a third component 3 which are contacted and spliced ​​into a whole in pairs, and the first component 1 and the second component 2 of the glue baffle plate are connected by plugging in the upper and lower positions, and the third component 3 is connected and combined with the combined first component 1 and the second component 2 by plugging in the front and rear positions. One side of the first component 1 and the second component 2 is respectively provided with an upper roller contact surface 9 and a lower roller contact surface 13, which are respectively consistent with the upper glue coating roller contact surface and the lower glue roller contact surface.

[0022] There is a gap between the first component 1, the second component 2 and the third component 3, the gap height is 1-2mm, and the gap is filled with felt, which acts as a spring and prevents glue penetration. At the same time, the role of the felt is to utilize the elasticity of the felt. The fixed component 3, the felt elastically pushes the first component 1 and the second component 2 forward, and presses them tightly on the glue roller; the first component 1 and the second component 2 are elastically combined by the felt to adapt to the change of the gap between the coating rollers, ensuring that the glue blocking plate is tightly attached to the coating roller without leaking glue.

[0023] The sides of the two oppositely arranged third components 3 away from the first component 1 and the second component 2 are respectively connected to the two ends of the glue tank bottom plate 17. The left and right sets of glue baffles, the upper and lower glue coating rollers, and the glue tank bottom plate 17 form a glue tank, and the resin is contained in the glue tank.

[0024] A protrusion extends from the upper end of the component fixing plate 4, and the two ends of the device position fixing rod 16 pass through the two protrusions respectively, so that the left and right sets of rubber baffles can be moved on the width of the rubber groove.

[0025] like Figures 3 to 5 As shown, a first bolt hole 8 is opened on the first component 1, a second bolt hole 12 is opened on the second component 2, and a third bolt hole 15 is opened on the third component 3. The fixing bolt 5 passes through the first bolt hole 8, the second bolt hole 12 and the third bolt hole 15 respectively and is fixed on the component fixing plate 4.

[0026] A vertical groove 14 is provided on the side of the third component 3 that contacts the first component 1 and the second component 2, and an upper protrusion 6 and a lower protrusion 11 that match the vertical groove 14 are provided on the side of the first component 1 and the second component 2 that contact the third component 3. After being combined, the third component 3 clamps the first component 1 and the second component 2 to prevent the glue from penetrating. An oblique protrusion 7 is provided on the side of the first component 1 that contacts the second component 2, and an oblique groove 10 that matches the oblique protrusion 7 is provided on the side of the second component 2 that contacts the first component 1. After being combined, the second component 2 clamps the first component 1 to prevent the glue from penetrating.

[0027] Preferably, the material of the first component 1, the second component 2 and the third component 3 includes tetrafluoroethylene to ensure that the rubber baffle does not damage the roller.

[0028] The specific assembly and installation steps of the glue baffle for a coating machine of the present invention are as follows:

[0029] Step 1: Place a sheet of felt strips into the oblique groove 10 of the second component 2;

[0030] Step 2: insert the oblique protrusion 7 of the first component 1 into the oblique groove 10 of the second component 2 to press the felt;

[0031] Step 3: Place a sheet of felt strips into the vertical groove 14 of the third component 3, flush with the bottom of the groove;

[0032] Step 4: insert the raised strip (upper protrusion 6 and lower protrusion 11) formed by combining the first component 1 and the second component 2 into the vertical groove 14 of the third component 3 to form an integral assembly of the polytetrafluoroethylene rubber baffle;

[0033] Step 5: Place the assembly against the component fixing plate 4, and fix the corresponding components through the screw holes on the component fixing plate with screws to form an integral rubber baffle;

[0034] Step 6: Place the left and right sets of integral rubber baffles between the upper and lower coating rollers and the rubber groove bottom plate 17;

[0035] Step 7: Pass the fixing rod of the rubber baffle plate installation position through the round holes above the two sets of integral rubber baffle plates, and then fix the integral rubber baffle plates according to the width requirements.

[0036] Step 8: Fix both ends of the rubber baffle plate fixing rod to the equipment.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention.
