Description

Technical Field

[0001] This utility model relates to tire manufacturing equipment, specifically an intelligent protection system for the guide rail of a giant tire forming machine. Background Technology

[0002] In the existing giant tire forming machine, during the gasoline application process, the adhesive slurry is easily splashed onto the guide rails of the machine bed, causing the slide block assembly that slides with the guide rails to stick and become damaged.

[0003] Due to the high cost of replacing slide components and the long downtime, there is an urgent need for an automated protection solution to address this problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes an intelligent protection system for the guide rails of a giant tire forming machine, designed to protect the guide rails on the machine bed from adhesive contamination.

[0005] A smart protection system for guide rails of a giant tire forming machine, capable of solving existing technical problems, includes a machine bed with two left- and right-oriented guide rails (front and rear). A spindle box is slidably mounted on the front and rear guide rails via corresponding slide assemblies. The spindle box moves left and right on the front and rear guide rails, carrying the moving tire blank into and out of the forming and unloading stations. The difference lies in:

[0006] 1. The bed is equipped with a guide rail protection device that can extend and retract forward and backward on the inner side of each guide rail at the tire unloading station. Each guide rail protection device includes a cover plate facing left and right. The cover plate is mounted on a slider by a bracket. The slider is slidably mounted on the linear guide rails facing forward and backward. The cover plate moves forward and backward under the extension and retraction of the cylinders set on the bed.

[0007] 2. A trigger plate is provided on the bed of the shaping station, and a switch that can sense the trigger plate is provided on the spindle box. The switch is connected to the cylinder through a circuit.

[0008] 3. When the spindle box moves from the shaping station to the unloading station, the switch and trigger plate sense and send a signal, and the cylinder retracts to move the cover plate inward to expose the guide rail; when the spindle box returns from the unloading station to the shaping station, the switch and trigger plate sense and send a signal again, and the cylinder extends to move the cover plate outward to block the guide rail.

[0009] Furthermore, the bed is provided with multiple bearing assemblies arranged in the left and right directions, and each bearing assembly is rolled and supported at the bottom of the cover plate to prevent the cover plate from being suspended and deformed when it moves forward and backward.

[0010] Furthermore, the spindle box is driven by a gear and rack transmission pair driven by a motor.

[0011] Furthermore, the response time of the cylinder and switch is less than 0.3 seconds to ensure that the cover plate and the spindle box move synchronously.

[0012] The beneficial effects of this utility model are:

[0013] 1. The intelligent protection system for the guide rail of the giant tire forming machine has a simple structure, stable and precise operation, convenient installation and maintenance, significantly extends the service life of the slide assembly, and reduces the maintenance cost of the equipment.

[0014] 2. This utility model adopts inductive switch linkage control, which has a fast response speed.

[0015] 3. This utility model uses a bearing assembly to support the cover plate, thus preventing it from being suspended and deformed. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the embodiments shown in the accompanying drawings.

[0020] This utility model relates to an intelligent protection system for the guide rails of a giant tire forming machine. It includes a bed 1, on which two guide rails 2 running left and right are mounted. A spindle box 3 is slidably mounted on the front and rear guide rails 2 via corresponding slide assemblies 4. Driven by a gear and rack transmission pair 14 driven by a motor, the spindle box 3 moves left and right on the front and rear guide rails, thereby moving the tire blank 5 into and out of the shaping station and the unloading station. The shaping station and the unloading station are located on the left and right sides of the bed 1, respectively. Figure 1 As shown.

[0021] At the tire unloading station, the bed 1 on the inner side of each guide rail 2 is equipped with a guide rail protection device that can extend forward and backward. Each guide rail protection device includes a left- and right-facing cover plate 6. The cover plate 6 is installed on the left-, middle-, and right sliders 8 respectively via three sets of brackets 7. The installation height of the cover plate 6 is higher than that of the guide rail 2. The left-, middle-, and right sliders 8 are slidably installed on the left-, middle-, and right linear guide rails 9 (forward and backward directions) respectively. A cylinder 10 is installed on the bed 1 corresponding to the bracket 7 in the middle position. The cylinder 10 extends horizontally forward. The cylinder rod is hinged to the bracket 7 in the middle position. The extension and retraction of the cylinder rod can drive the cover plate 6 to move forward and backward. At the tire unloading station, the bed 1 is provided with six bearing assemblies 13 arranged in a left-right direction. Each bearing assembly 13 rolls and supports the bottom of the cover plate 6 to prevent the cover plate 6 from being suspended and deformed when moving forward and backward. Specifically, two bearing assemblies 13 are set between each adjacent bracket 7. One bearing assembly 13 is set on the left side of the bracket 7 in the left position, and one bearing assembly 13 is set on the right side of the bracket 7 in the right position. Figure 1 , Figure 2 As shown.

[0022] A trigger plate 11 is installed on the bed 1 at the shaping station. A switch 12, which senses the trigger plate 11, is installed on the spindle box 3. The switch 12 is connected to the front and rear cylinders 10 via wiring. The response time between each cylinder 10 and the switch 12 is less than 0.3 seconds to ensure that the front and rear cover plates 6 move synchronously with the spindle box 3. Figure 1 , Figure 2 As shown.

[0023] The operation mode of this utility model is as follows:

[0024] 1. When the spindle box 3 carries the tire blank 5 from the shaping station to the unloading station, the switch 12 and the trigger plate 11 sense each other and send signals to each cylinder 10 at the same time. The cylinder rods of each cylinder 10 retract synchronously, driving the front and rear cover plates 6 to move inward synchronously along the corresponding linear guide rails 9, exposing the guide rails 2 that were originally covered by the cover plates 6, so that the spindle box 3 can smoothly enter the unloading station.

[0025] 2. After the tire is removed, when the spindle box 3 returns from the tire removal station to the shaping station, the switch 12 and the trigger plate 11 sense each other and send a signal to each cylinder 10 at the same time. The cylinder rods of each cylinder 10 extend synchronously, driving the front and rear cover plates 6 to move outward synchronously along the corresponding linear guide rail 9 to block the guide rail 2.

[0026] At this point, the gasoline application process can begin. Since each guide rail 2 is covered by its corresponding cover plate 6, the guide rail 2 is effectively protected from splashing adhesive and thus prevented from becoming contaminated.
