Description

Technical Field

[0001] The invention relates to auxiliary equipment for producing silent tires, in particular to an automatic glue coating device for the end section of a belt-shaped noise reduction member and a glue coating system containing the device. Background Art

[0002] When manufacturing silent tires with silent materials (such as silent sponges) on the inner wall of the tire, some customers' processes require that the cross section of the head end of the silent sponge be bonded to the cross section of the tail end to form a ring. Currently, there are two ways to bond the head end and the tail end of the silent sponge:

[0003] One is the method used by foreign tire factories: first use a spray head to manually spray glue on the cross-sections of the two ends of the sponge, then manually align the two cross-sections and press them together for a certain period of time, then let the initially attached annular sponge stand freely for a period of time to allow the glue to solidify, and then attach the sponge to the inside of the tire through a bonding mechanism or manually. When attaching annular sponges in this way, the nozzle is likely to spray glue on other surfaces except the cross-section, contaminating the sponge. At the same time, it is difficult to ensure the uniformity of manual spraying, the efficiency is low, and the environmental VOC value is high, which is harmful to the human body.

[0004] The other method is adopted by domestic tire factories, which is to first stick the sponge to the inner wall of the tire to form a docking method, then manually dip a brush in glue, and then manually pull apart the cross-section joints at the head and tail ends of the silent sponge to expose the end face of the joint, and then manually apply glue with a brush and reset the cross section of the joint to make the end face bonded. This method of manually handling the joint requires pulling apart and then applying glue to restore it. The process is complicated and it is easy to destroy the flatness of the original joint. The uniformity of manual glue application is poor, and the weight is difficult to control. When the glue overflows, the appearance of the joint is poor. Summary of the invention

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0033] See attached Figures 1 to 3The first embodiment of the present invention is shown, which discloses an automatic gluing device 10 for the end section of a strip noise reduction member, which includes a glue barrel 11, a conduit (not shown), a glue pumping device 12 and a glue driving assembly 13, and a glue roller brush 14 connected to the glue driving assembly 13; wherein, one end of the conduit is connected to the glue barrel 11, and the other end of the conduit is connected to the glue pumping device 12 and then extends to the glue roller brush 14, the glue driving assembly 13 includes a glue driver 131, and the driving end of the glue driver 131 is clutch-connected to the glue roller brush 14, and the clutch connection, that is, the driving end of the glue driver 131 and the glue roller brush 14 can be separated or contact-connected as needed.

[0034] Specifically, the first embodiment of the present invention also includes a bracket 20, a bracket seat 21 and a lifting driver 30 (such as an electric cylinder or a cylinder). The lifting driver 30 is arranged on the bracket seat 21 (the bracket seat can be independently arranged or fixed to other equipment), and the driving end of the lifting driver 30 is provided with a connecting plate 132. The lifting driver 30 can drive the connecting plate 132 to move up and down. The connecting plate 132 is provided with a cylinder seat 137, a gluing driver 131 (such as a pneumatic motor), a second gluing driver 133 (cylinder), an active roller 134, a driven roller 135 and a driven roller seat 138. The driving end of the gluing driver 131 can be synchronously rotatably connected with the active roller 134, and the driving end of the second gluing driver 133 is provided with a support 136. The active roller 134 is arranged on the support 136, and the driven roller 135 is arranged on the driven roller seat 138 and is arranged corresponding to the active roller 134 (such as the first embodiment). Figure 3 The driven roller 135 and the glue roller brush 14 are connected to each other in a synchronously rotatable manner (such as coaxially connected). The lifting drive 30 is a non-essential component. If the strip-shaped noise reduction member can be moved, the connecting plate 132 can be directly regarded as a part of the bracket 20, that is, the glue roller brush 14 fixed on the bracket 20 can be passively rotated by moving the strip-shaped noise reduction member, so that the glue on its surface can be applied to the cross section of the end of the strip-shaped noise reduction member.

[0035] Through the above configuration, when the end section of the strip noise reduction member needs to be coated with glue, the second glue coating driver 133 first drives the support 136 to move upward, so as to drive the glue coating driver 131 and the active roller 134 to move upward, so as to achieve contact between the active roller 134 and the driven roller 135, and then the glue in the glue barrel 11 is sprayed onto the glue coating roller brush 14 through the guide tube (not shown) by the glue pump device 12. While the glue is sprayed on the glue coating roller brush 14, the driving active roller 134 of the glue coating driver 131 rotates to drive the driven roller 135 to contact the glue coating roller 14. The roller brush 14 rotates to ensure that the glue is evenly attached to the surface of the glue-coating roller brush 14; then the active roller 134 is separated from the driven roller 135, and the connecting plate 132 is driven by the lifting driver 30 to move upward to the glue coating position. When the end section of the strip noise reduction member contacts the surface of the glue-coating roller brush 14, the lifting driver 30 drives the connecting plate 132 to move up and down to achieve the relative movement of the glue-coating roller brush 14 and the end section of the strip noise reduction member, thereby transferring the glue on the surface of the glue-coating roller brush 14 to the section at the tail end of the strip noise reduction member, and then resetting it.

[0036] Preferably, as attached Figure 1 and 2 As shown, the present invention also includes a glue recovery component 40 for recovering glue, the glue roller brush 14 is arranged corresponding to the glue recovery component 40 (such as being arranged above the glue recovery component 40), and the glue recovery component 40 is provided with a scraper plate 41 which is tangent to the surface of the glue roller brush 14 and inclined, and the scraper plate 41 is arranged adjacent to the glue roller brush 14. When the conduit sprays glue on the surface of the glue roller brush 14 and rotates, redundant glue is scraped off by the scraper plate 41, further ensuring that the glue on the surface of the glue roller brush 14 is evenly distributed, thereby achieving uniform glue coating on the end cross section of the strip-shaped noise reduction component.

[0037] In addition, to further ensure that the glue-coating roller brush 14 is precisely connected to the end section of the strip-shaped noise reduction member, a positioning detection element 50 (such as a photoelectric switch, a distance measuring switch, a limit switch, etc.) can be provided on the connecting plate 132. Specifically, the positioning detection element 50 can be provided on the connecting plate 132 above the driven roller 135.

[0038] Preferably, as attached Figure 5 As shown, a fixed support 60 is provided on the bracket 20 of the present invention, a fixed driver 61 (such as a cylinder) is provided on the fixed support 60, and a fixed element 62 (such as a pressure strip) is provided at the driving end of the fixed driver 61. After the strip-shaped noise reduction member is transported to the predetermined position, the reserved part of the strip-shaped noise reduction member is fixed by the fixed driver 61 driving the fixed element 62 to prevent the reserved part of the strip-shaped noise reduction member from swinging freely.

[0039] Optionally, when the end of the strip-shaped noise reduction member is a sloped structure (i.e., the cross-section of the strip-shaped noise reduction member along the length direction is a trapezoid), the glue coating roller brush 14 described in the present invention can be set to an angle-adjustable mode to match the end cross-sections of different strip-shaped noise reduction members to achieve a better glue coating effect.

[0040] Attached Figure 4 This is the second embodiment of the present invention, which is different from the first embodiment in that the glue-coating drive assembly 13 in the second embodiment includes a base 139 fixedly arranged on a connecting plate 132, and the glue-coating drive 131 (such as a servo motor) is arranged on the base 139, and the driving end of the glue-coating drive 131 is directly connected to the glue-coating roller brush 14. The advantage of this configuration structure is that when the strip-shaped noise reduction member is relatively soft, the relative movement between the glue-coating roller brush 14 and the end face of the strip-shaped noise reduction member is passive rolling, and it may happen that the strip-shaped noise reduction member is relatively soft and cannot provide sufficient friction to enable the glue-coating roller brush 14 to complete the cross-sectional rolling brushing action. By driving the glue-coating roller brush 14 to rotate actively through a servo motor to transfer the glue to the end face of the soft strip-shaped noise reduction member, the above-mentioned problem can be overcome.

[0041] Attached Figure 6 With attached Figure 7 Schematic diagram of the third embodiment of the present invention. Figure 6 With attached Figure 7 As shown, the difference between the third embodiment and the first embodiment is that the third embodiment includes a glue box 70, and the other end of the conduit is connected to the glue pump device 12 and extends to the top or inside of the glue box 70 to provide glue to the glue box 70; the glue application drive assembly 13 includes a cylinder 131, and the drive end of the cylinder 131 is directly connected to the glue application roller brush 14. Specifically, the drive end of the cylinder 131 is provided with a connecting piece 80, and the glue application roller brush 14 is provided on the connecting piece 80 and can rotate freely. When the end section of the strip-shaped noise reduction member needs to be coated with glue, as shown in the attached Figure 6 As shown, the cylinder 131 first drives the glue roller 14 to roll back and forth in the glue box 70 to attach glue to the surface of the glue roller 14, and then the lifting driver 30 drives the connecting plate 132 to move upward to the glue coating position (such as the attached Figure 7 As shown in the figure), when the end section of the strip noise reduction member contacts the surface of the glue roller brush 14, the lifting drive 30 drives the connecting plate 132 to move, so as to realize the relative movement of the glue roller brush 14 and the end section of the strip noise reduction member, thereby transferring the glue on the surface of the glue roller brush 14 to the section at the tail end of the strip noise reduction member, and then resetting it.

[0042] The present invention also discloses an automatic gluing method for the end section of a strip-shaped noise reduction member, wherein the length of the strip-shaped noise reduction member is substantially equal to the inner circumference length of the tire, and the method comprises the following steps: applying adhesive to the surface of a roller brush; winding the strip-shaped noise reduction member and reserving a certain length at the tail end of the rolled strip-shaped noise reduction member; contacting a roller brush with adhesive on the surface with the cross section of the tail end of the strip-shaped noise reduction member; transferring the adhesive on the surface of the roller brush to the cross section of the tail end of the strip-shaped noise reduction member by rolling the roller brush; and placing the strip-shaped noise reduction member with adhesive applied on the cross section of the tail end on the inner wall of the tire. The reserved length of the tail end of the rolled strip-shaped noise reduction member is 5 cm to 50 cm; the circumference of the roller brush is greater than the length of the cross section of the end of the strip-shaped noise reduction member, and preferably the length of the cross section of the end of the strip-shaped noise reduction member is 5 cm to 30 cm; the width of the glue-applying roller brush is greater than the width of the cross section of the end of the strip-shaped noise reduction member, and preferably the width of the cross section of the end of the strip-shaped noise reduction member is 1 cm to 6 cm.

[0043] As attached Figure 8 To Attachment Fig.10 As shown, the present invention also discloses an automatic gluing system (not shown) for the end section of a strip-shaped noise reduction member, which includes a laminating device 100 for applying a strip-shaped noise reduction member 300 to the inner surface of a tire (the specific structure and principle can be found in the applicant's 2021107198672 invention patent content), and the laminating device is provided with a laminating component 101 for rolling and unrolling the strip-shaped noise reduction member, and also includes the automatic gluing device 10 as described above, and the automatic gluing device 10 and the laminating component 101 can move relative to each other (such as the automatic gluing device 10 moves, that is, the gluing roller brush 14 moves up and down, or the laminating component 101 moves, that is, the strip-shaped noise reduction member moves up and down). Therefore, when the laminating component 101 is rolling, as shown in the attached Fig. 9 As shown, after the strip-shaped noise reduction member 300 is wound into a roll, a certain length is reserved at the tail end of the strip-shaped noise reduction member 300, and the section 301 of the tail end is arranged corresponding to the glue roller brush 14 in the automatic glue coating device 10. After the glue is applied to the section 301 by the automatic glue coating device 10, the bonding component 101 continues to complete the rolling action, and then the strip-shaped noise reduction member 300 is applied to the inner wall of the tire 400. Since the section 301 of the strip-shaped noise reduction member 300 has been evenly coated with glue, when the head and tail ends of the strip-shaped noise reduction member 300 are connected, the glue at the section 301 can bond the two end faces.

[0044] Description: The strip noise reduction member described in the present invention is a rectangular parallelepiped or a strip silent sponge with a rectangular body but inclined ends; the glue pump device 12 is a peristaltic pump, a diaphragm pump, a plunger pump, a gear pump, a screw pump, etc.

[0045] It can be known from the above-disclosed technical contents that the automatic gluing device for the end section of the strip-shaped noise reduction component described in the present invention is mainly designed by including a glue barrel, a conduit, a glue pumping device and a glue driving assembly, and a glue roller brush connected to the glue driving assembly; wherein, one end of the conduit is connected to the glue barrel, and the other end of the conduit is connected to the glue pumping device. Through the above-mentioned configuration structure, technical effects such as automatically, accurately and efficiently coating glue on the end section of the strip-shaped noise reduction component can be achieved.

[0046] The above contents are only some implementation methods of the present application, and their purpose is to illustrate the technical concept and features of the present application.
