[0037] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, solution and effects of the present utility model. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The same reference numerals used throughout the drawings indicate the same or similar parts.

[0038] It should be noted that, unless otherwise specified, when a certain feature is referred to as "fixed" or "connected" to another feature, it can be directly fixed or connected to the other feature, or indirectly fixed or connected to the other feature. In addition, the descriptions such as up, down, left, and right used in the present utility model are only relative to the mutual positional relationship of the components of the present utility model in the drawings.

[0039] Referring to Figures 1 to 4 , a rubber strip pasting device, comprising a housing 1 and a guiding mechanism 2, an elastic reset mechanism 3 and a cutter 4 installed in the housing 1. The guiding mechanism 2 includes a rubber strip pressing wheel 21, a rubber strip guiding wheel 22, a release paper pressing wheel 23 and a release paper guiding wheel 24 which are rotatably and fixedly connected to the first main body 11 of the housing 1. The rubber strip 91 can be applicable to a sealing rubber strip 91, etc. A release paper 92 is pasted on one side of the rubber strip 91 to form a rubber strip 9 with a release paper pasted thereon. The rubber strip pressing wheel 21, the rubber strip guiding wheel 22, the release paper pressing wheel 23 and the release paper guiding wheel 24 are all roller structures that rotate around their central axes. The central axes of the rubber strip pressing wheel 21, the rubber strip guiding wheel 22, the release paper pressing wheel 23 and the release paper guiding wheel 24 are all parallel to each other. The axes of the central axes of the rubber strip pressing wheel 21, the rubber strip guiding wheel 22 and the release paper pressing wheel 23 are located in the same horizontal plane. The linear speeds of the rubber strip pressing wheel 21, the rubber strip guiding wheel 22, the release paper pressing wheel 23 and the release paper guiding wheel 24 are the same. A feed knob 119 protrudes from the housing 1. The feed knob 119 extends into the housing 1 and is connected to the rubber strip guiding wheel 22. When the feed knob 119 is rotated, the rubber strip guiding wheel 22 can be driven to rotate synchronously. When installing or replacing the rubber strip 91 before the rubber strip pasting device in this solution is used, rotating the feed knob 119 can drive the rubber strip 91 and the release paper 92 to pass through the gaps between the corresponding rollers.

[0040] A first channel 113 through which a rubber strip 9 with a release paper pasted thereon can pass is provided inside the housing 1. An inlet 111 and an outlet 112 are sequentially provided at the upper and lower ends of the housing 1. The upper ends of the first channel 113 and the second channel 13 are both communicated with the inlet 111, and the lower ends are both communicated with the outlet 112. The rubber strip pressing wheel 21, the rubber strip guiding wheel 22, and the release paper pressing wheel 23 are parallel to each other in the horizontal direction and are sequentially arranged at intervals near the inlet 111. The rubber strip 9 with the release paper pasted thereon can enter the housing 1 from the inlet 111 and pass through the gap between the rubber strip pressing wheel 21 and the rubber strip guiding wheel 22, and this gap forms a part of the first channel 113. A second channel 13 through which the release paper 92 can pass is further provided inside the housing 1. The release paper guiding wheel 24 is installed at the outlet 112. The release paper guiding wheel 24 is rotatably and fixedly connected to the housing 1. The release paper guiding wheel 24 is located between the first channel 113 and the second channel 13, and the release paper guiding wheel 24 is located below the rubber strip guiding wheel 22. A stop block 114 is further provided at the lower end of the housing 1. A third channel 14 through which the rubber strip 91 can pass is formed on the side surface of the stop block 114. The upper end of the third channel 14 is communicated with the lower end of the first channel 113. The gap between the rubber strip guiding wheel 22 and the release paper pressing wheel 23 forms a part of the second channel 13. The rubber strip 91 separated from the release paper 92 can move downward along the side surface of the stop block 114 away from the cutting knife and extend out of the housing 1 from below the stop block 114. The lower end of the first channel 113 is communicated with the lower end of the second channel 13. The release paper can enter the lower end of the second channel 13 from the lower end of the first channel 113, that is, the release paper 92 can bypass from below the release paper guiding wheel 24 and enter upward into the second channel 13 where the release paper can freely pass. When the release paper 92 moves upward in the second channel 13, it can pass through the gap between the rubber strip guiding wheel 22 and the release paper pressing wheel 23 and then extend out from the upper end of the housing 1. The release paper 92 is peeled off at the outlet 112 to be separated from the rubber strip 91. The lower end of the stop block 114 is used to press the rubber strip 91 so that the rubber strip 91 is bonded to the workpiece. When the workpiece and the rubber strip pasting device move relatively, the bonding force between the rubber strip 91 and the workpiece pulls the rubber strip 91 to pass through the first channel 113 inside the device, thereby realizing the automatic pasting or automatic feeding of the sealing rubber strip 91.

[0041] When the adhesive tape 91 advances under the traction of the adhesive force, it drives the adhesive tape guide wheel 22 to rotate. The rotating adhesive tape guide wheel 22 drives the release paper 92 to be output from the inlet 111 in the opposite direction of the movement of the adhesive tape 91 under the pressure of the release paper pressing wheel 23, so as to realize the automatic peeling of the release paper 92. Since both the adhesive tape 91 and the release paper 92 are in contact with the adhesive tape guide wheel 22, the adhesive tape 91 and the release paper 92 have the same speed, and the linear speeds of the adhesive tape pressing wheel 21, the adhesive tape guide wheel 22, the release paper pressing wheel 23, and the release paper guide wheel 24 are the same.

[0042] The elastic reset mechanism 3 is installed on the housing 1 and is connected to the cutting knife 4. The elastic reset mechanism 3 is provided with a pressing part protruding outside the housing 1. When pressing down the pressing part, the cutting knife 4 can be driven to move downward. When the cutting knife 4 moves downward, it can cut off the adhesive tape 91 moving below it. When the pressing part is released, the pressing part moves upward and can drive the cutting knife 4 to move upward and reset. The cutting knife 4 is located on the side of the stopper away from the third channel 14 in the horizontal direction. Pressing down the elastic reset mechanism 3, the elastic reset mechanism 3 can cut off the adhesive tape 91 when it moves downward; after releasing the external force, the elastic reset mechanism 3 and the cutting knife 4 reset upward. The cutting knife 4 is located on the side of the stopper 114 away from the adhesive tape 91 in the horizontal direction.

[0043] The adhesive tape pasting device of this solution has a simple structure and can smoothly separate the adhesive tape 91 from the release paper 92 during use; the adhesive tape 91 can be positioned by the stopper 114, and the turning or turning process of the straight-line, circular, and curved pasting requirements can be completed more smoothly. The setting of the stopper 114 makes it convenient to paste the adhesive tape 91 on the non-straight path, improving the pasting efficiency of the adhesive tape 91 on the non-straight path; after pasting, pressing down the elastic reset mechanism 3 drives the cutting knife 4 to move downward, and the adhesive tape 91 can be cut off, and the cutting knife 4 can be automatically driven to reset after releasing the hand, with simple operation and improved pasting efficiency of the adhesive tape 91.

[0064] Both the first body 11 and the second body 12 can be made of aluminum alloy. The docking of the first body 11 and the second body 12 can be set in the shape of a pen holder, and the size of the lower end is smaller than that of the upper end. The structure is small and delicate. The outer diameter of the housing 1 can be preferably 30 mm, and the overall weight can be set to less than 250 grams, which is very suitable for being grasped by hand and will not make people feel tired after long-term use. This device has rich functions and reasonable structural arrangements. The operator can use it without mastering complex skills and can easily complete the work of pasting the sealing strip 91 with high quality. This solution can be applied to the sealing strip 91 with a specification of only 3.5 mm × 1 mm, that is, it is applicable to the pasting of the sealing strip 91 with a small cross-section. The housing 1 at the position of the strip outlet 112 of this device is designed in the shape of a pen tip, which can be smoothly applied to pasting the strip 91 in a narrow groove. The stop block 114 forms a pen tip structure, and positioning can be performed through the sides of the stop block 114 located on both sides of the strip 91 to complete the turning or turning process of pasting requirements such as linear, circular, and curved. The overall structure of the strip pasting device of this solution is simple, small, light, and flexible in operation. When in use, as the strip 91 extends, the release paper 92 on the strip 91 can be automatically peeled off, greatly reducing the difficulty of pasting the strip 91 and improving the pasting efficiency of the strip 91. The strip 91 extends out from the lower end of the stop block 114 and is accurately positioned through the stop block 114, which can improve the pasting quality of the strip 91, reduce pasting mistakes, reduce the waste of strip 91 materials, and save the time for pasting the strip 91 at the same time.
