Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a spraying auxiliary guide device for an external water-cut sealing strip. Background Art

[0002] like Figure 1 As shown, the sealing lip 1.1 of the external water-cut sealing strip 1 in the prior art faces the glass and is squeezed and interfered with by the glass to form a seal. Since the friction between the sealing lip 1.1 and the sealing strip body 1.2 is relatively large when they are in contact with each other, the external water-cut sealing strip 1 is easily worn, thereby reducing the performance of the sealing strip. Usually, a protective layer 1.3 is sprayed on the top of the sealing strip body 1.2 facing the sealing lip 1.1, so as to reduce the friction between the sealing strips, thereby reducing the wear and extending the service life of the sealing strip.

[0003] However, since the protective layer 1.3 is blocked by the sealing lip 1.1, part of the spraying area is covered, the spraying is difficult, and the spraying is unstable due to under-spraying. Therefore, it is urgent to design a spraying auxiliary guide device for spraying a comprehensive and stable external water-cut sealing strip. Utility Model Content

DETAILED DESCRIPTION

[0022] See also Figure 1-6 The utility model relates to a spraying auxiliary guide device for an external water-cut sealing strip, comprising a fixed card slot seat 2, a U-mouth guide wheel 3, a side pressure roller 4, a first lip edge pressure and expansion wheel assembly 5 and a second lip edge pressure and expansion wheel assembly 6. A U-mouth guide wheel 3 is arranged between the left and right fixed card slot seats 2, and the two guide wheels are arranged front and back. The external water-cut sealing strip 1 is inserted on the U-mouth guide wheel 3, and the U-mouth guide wheel 3 is rotatably arranged on the guide wheel shaft through a bearing. The guide wheel shaft is fixed on two fixed card slot seats 2, and the fixed card slot seat 2 is fixed in a spraying chamber. A card slot is arranged at the bottom of the fixed card slot seat 2, and a guide rail is arranged in the spraying chamber corresponding to the card slot. A fixing screw 7 is arranged on the fixed card slot seat 2 on one side, and the fixing of the fixed card slot seat 2 is achieved by the fixing screw 5.

[0023] The first lip pressure spreading wheel assembly 5 and the second lip pressure spreading wheel assembly 6 are arranged on the sealing lip side of the outer watertight sealing strip 1 , and the side pressure roller 4 is arranged on the other side of the outer watertight sealing strip 1 .

[0024] The first lip edge pressure spreading wheel assembly 5 comprises a first rod seat 5.1, a first vertical adjustment screw 5.2, a first lip edge pressure spreading wheel seat 5.3 and a first lip edge pressure spreading wheel 5.4. The first rod seat 5.1 is fixed on the fixed slot seat 2. The first vertical adjustment screw 5.2 is rotatably arranged in the first rod seat 5.1. The first vertical adjustment screw 5.2 is connected to the first lip edge pressure spreading wheel seat 5.3. The first lip edge pressure spreading wheel seat 5.3 is connected to the first lip edge pressure spreading wheel 5.4. The heights of the two first lip edge pressure spreading wheels 5.4 arranged front and back decrease in sequence. By rotating the first vertical adjustment screw 5.2, the first lip edge pressure spreading wheel seat 5.3 is adjusted up and down in height, driving the first lip edge pressure spreading wheel 5.4 to adjust its height up and down.

[0025] The first lip pressure spreading wheel 5.4 is waist-shaped, which facilitates the spreading of the sealing lip 1.1.

[0026] The first lip spreading wheel 5.4 and the second lip spreading wheel 6.4 are both inclined upwards at one side close to the sealing lip, so as to facilitate the spreading of the spraying area.

[0027] The second lip edge pressure wheel assembly 6 is arranged behind the first lip edge pressure wheel assembly 5, and the second lip edge pressure wheel assembly 6 includes a second rod seat 6.1, a second vertical adjustment screw 6.2, a second lip edge pressure wheel seat 6.3 and a second lip edge pressure wheel 6.4. The second rod seat 6.1 is fixed on the fixed slot seat 2, and the second vertical adjustment screw 6.2 is rotatably arranged in the second rod seat 6.1. The second vertical adjustment screw 6.2 is connected to the second lip edge pressure wheel seat 6.3, and the second lip edge pressure wheel seat 6.3 is connected to the second lip edge pressure wheel 6.4. The two second lip edge pressure wheels 6.4 arranged in front and behind are located at the same height, and the first lip edge pressure wheel 5.4 at the rear is higher than the second lip edge pressure wheel 6.4. The second vertical adjustment screw 6.2 is rotated, and the second lip edge pressure wheel seat 6.3 is adjusted up and down in height, driving the second lip edge pressure wheel 6.4 to adjust its height up and down. The first vertical adjusting screw 5.2 and the second vertical adjusting screw 6.2 are adjusted to adjust the height of the first lip spreading wheel 5.4 and the second lip spreading wheel 6.4, so that the height of each lip spreading wheel is gradually changed, and the sealing lip is gradually spread by each lip spreading wheel, so that the sealing strip lip opens a large enough area for spraying.

[0028] The spray gun is arranged between the two second lip edge pressure spreading wheels, and the spray gun is aimed at the side of the sealing strip body 1.2 facing the sealing lip edge 1.1. The distance between the two second lip edge pressure spreading wheels is controlled at 90-110mm, so that there is enough area for spraying and the lip edge does not rebound due to the long distance, thereby reducing the lip edge pollution caused by the spraying area.

[0029] The side pressure roller 4 can be adjusted left and right, and the side pressure roller 4 is rotatably arranged on the top of the side pressure roller seat 8, and the side pressure roller seat 8 is sleeved on the side pressure roller adjustment screw 9, and the side pressure roller adjustment screw 9 is rotatably arranged on the third rod seat 10, and the two ends of the third rod seat 10 are respectively fixed on the corresponding fixed card slot seat 2. The side pressure roller 4 can be adjusted left and right to a suitable position by the side pressure roller adjustment screw 9, and the lateral force is applied from the side to fix the sealing strip to prevent the lip from unfolding and the pressure wheel from pressing down, which causes the product to be unstable and overturn.

[0030] Working principle:

[0031] The U-mouth of the outer water-cut sealing strip 1 is vertically inserted into the U-mouth guide wheel, and the U-mouth guide wheel drives the outer water-cut sealing strip to be pulled backward. The two U-mouth guide wheels are arranged front and back to increase the stability of the outer water-cut sealing strip 1 to be pulled backward;

[0032] The side pressure wheel can be adjusted left and right to a suitable position through the side pressure wheel adjustment screw, and lateral force is applied from the side to fix the sealing strip to prevent the lip from unfolding and the pressure wheel from pressing down, causing the product to turn over and become unstable;

[0033] The first vertical adjustment screw and the second vertical adjustment screw are adjusted to adjust the height of the first lip pressure wheel and the second lip pressure wheel, so that the height of each lip pressure wheel is gradually changed, and the sealing lip is gradually pressed and spread by each lip pressure wheel, so that the sealing strip lip opens a large enough area for spraying operation.

[0034] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
