Description

Technical Field

[0001] The invention relates to the technical field of solid rubber tire production, in particular to a rubber strip end surface bonding and pressing device for a solid rubber tire. Background Art

[0002] Solid tires are industrial tires suitable for vehicles running under low speed, high load and harsh conditions. The existing production of rubber solid tires requires rolling the rubber strip into a solid tire shape (round) and then putting it into a mold for vulcanization molding.

[0003] After the rubber strip is rolled into a circle, adhesive needs to be applied to both end surfaces of the strip to bond the two ends together, so that the rubber strip can form a complete solid tire shape (circle). In order to prevent the bonding parts coated with adhesive from coming off (to ensure the bonding quality), manual compression (providing compression force) is usually performed. Manual compression is not only time-consuming and labor-intensive, but also cannot provide sufficient compression force and cannot ensure the bonding quality. Summary of the invention

[0004] The present invention aims to solve the problem that the two ends of the rubber strip in the prior art are bonded together by manual pressing, which is time-consuming and labor-intensive, cannot provide sufficient pressing force, and cannot ensure the bonding quality. The present invention provides a rubber strip end face bonding and pressing device for a rubber solid tire, which has a simple structure, is easy to use, can reduce labor intensity, and can provide sufficient pressing force to ensure the bonding quality of the rubber strip.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a rubber strip end face bonding and pressing device of a rubber solid tire of the present invention comprises a column, an upper pressure plate and a lower pressure plate, a first cylinder is fixed on the column, a piston rod of the first cylinder is fixedly connected to the upper pressure plate, a left-side pressing tooth is arranged on the bottom surface of the upper pressure plate along the width direction, the lower pressure plate is located below the upper pressure plate and is fixedly connected to the column, the upper pressure plate can move up and down relative to the lower pressure plate, a second cylinder is fixed on the right side of the top surface of the upper pressure plate, a piston rod end of the second cylinder is fixedly connected to an inclined top plate, an avoidance groove is arranged on the upper pressure plate, the inclined top plate passes through the avoidance groove, and a right-side pressing tooth is arranged on the end surface of the inclined top plate away from the second cylinder. The present invention provides the pressing force required for the bonding of the rubber strip through the first cylinder and the second cylinder, which not only saves time and labor and can reduce labor intensity, but also can provide sufficient pressing force to ensure the bonding quality of the rubber strip. When the present invention is used, the rubber strip is first rolled into a circle, and then adhesive is applied to the end surfaces at both ends of the rubber strip and bonded together, and then the rubber strip is hung on the lower pressing plate, and the bonding position (bonding gap) is located between the left pressing teeth and the right pressing teeth. Finally, the first cylinder is started to press the rubber strip between the upper pressing plate and the lower pressing plate so that it cannot move, and then the second cylinder is started to push out the inclined ejector plate. At this time, the extrusion effect of the left pressing teeth and the right pressing teeth applies pressure to the end surfaces of the rubber strip coated with adhesive at both ends, providing sufficient pressing force, so that the end surfaces of the rubber strip coated with adhesive at both ends can be firmly bonded together, thereby improving the bonding quality.

[0006] Preferably, the upper pressing plate and the lower pressing plate are both arc-shaped, and the concave surfaces of the upper pressing plate and the lower pressing plate are both facing downward. The upper pressing plate and the lower pressing plate are both arc-shaped, just matching the contour surface of the rubber strip rolled into a circle; the width of the upper pressing plate and the width of the lower pressing plate are both greater than the width of the rubber strip; the width of the upper pressing plate is smaller than the width of the lower pressing plate.

[0007] Preferably, an upper mounting plate is fixed to the upper end of the column, and the first cylinder is fixed on the upper mounting plate.

[0008] Preferably, an upper pressing plate guide mechanism is provided between the upper mounting plate and the upper pressing plate, and the upper pressing plate guide mechanism comprises a guide sleeve and a guide rod, the guide sleeve is fixed on the upper mounting plate, the guide rod passes through the guide sleeve and the upper mounting plate, a limit block is fixed on the upper end of the guide rod, and the lower end of the guide rod is fixedly connected to the upper pressing plate. The guide mechanism ensures that the upper pressing plate can always maintain linear motion up and down, thereby improving the running stability.

[0009] Preferably, a bracket is fixed on the right side of the top surface of the upper pressure plate, and the bracket includes two oppositely arranged side panels and a horizontal plate fixed on the side panels. The bracket as a whole is an inverted "U" shape structure, the second cylinder is fixed on the horizontal plate, and the piston rod of the second cylinder passes through the horizontal plate.

[0010] Preferably, guide grooves are provided on the opposite surfaces of the two side plates, and the side edges of the inclined top plate are located in the guide grooves and slide in the guide grooves. The side edges of the inclined top plate are located in the guide grooves and slide in the guide grooves, and the inclined top plate runs stably without shaking, which helps to improve the bonding quality of the rubber strip.

[0011] Preferably, a lower mounting plate is fixed on the column, the lower pressure plate is fixed on the lower mounting plate, and a reinforcing plate is provided between the lower mounting plate and the column.

[0012] Preferably, both sides of the lower pressing plate are provided with limiting flanges, which can prevent the rubber strip placed on the lower pressing plate from falling off the lower pressing plate.

[0013] Therefore, the present invention has the following beneficial effects: using the first cylinder and the second cylinder as power sources, and applying pressure to the end surfaces of the rubber strip coated with adhesive at both ends through the extrusion of the left-side clamping teeth and the right-side clamping teeth, thereby providing sufficient clamping force, which not only saves time and labor and reduces labor intensity, but also enables the end surfaces of the rubber strip coated with adhesive at both ends to be firmly bonded together, thereby improving the bonding quality.
