Description
Technical Field
[0001] The invention relates to the technical field of laying floor leather for buses, and in particular to a rolling tool for floor leather for buses and a use method thereof. Background Art
[0002] In the process of bus manufacturing, the floor covering (floor leather) inside the bus is an indispensable part. It not only affects the appearance of the vehicle, but also is related to the comfort of the passengers and the service life of the vehicle.
[0003] The existing technology for laying floor coverings for buses requires the cooperation of multiple people. The conventional method is that after the floor coverings are laid, the construction personnel use traditional roller pressing tools to roll the large surface of the floor coverings. These tools include basic components such as rollers and roller shafts. The rollers are manually pushed to roll on the floor coverings to achieve the purpose of compaction and bonding. However, the roller surface may be damaged during the placement or operation of the tooling, and the damaged roller will cause blistering and uneven defects on the surface of the floor coverings. In addition, due to the wide range of operation of the construction personnel, the number of rolling circles (or rolling times) of the rolling process is manually controlled by the construction personnel. During on-site operations, problems such as insufficient rolling effect and excessive rolling effect often occur, resulting in time-consuming and labor-intensive secondary rework, and the product quality and production efficiency cannot be guaranteed. Summary of the invention

[0023] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0024] As introduced in the background technology, the existing rolling tooling has the following problems: the traditional tooling is easy to damage the roller surface during the placement and transportation process, thereby affecting the surface quality of the floor leather. In addition, the manual control of the number of rolling times is easy to lead to insufficient or excessive rolling effect. Specifically: insufficient rolling effect or degree means that during the rolling process, the number of rolling times does not achieve the expected effect, resulting in the physical properties of the floor leather such as density, hardness or surface flatness failing to meet the design requirements. This may cause the floor leather to have insufficient performance during use, such as easy wear, poor wear resistance, poor compression resistance and other problems. Excessive rolling effect or degree is the opposite of insufficient rolling, which means that the number of rolling times exceeds the bearing capacity of the floor leather material, which may cause the floor leather to be over-compressed, over-hardened, deformed or surface cracked. Such floor leather may affect comfort due to excessive hardening in actual use, or affect appearance and service life due to deformation and cracks. In order to solve the above technical problems, this embodiment proposes a passenger car floor leather rolling tool, which uses auxiliary wheels for walking during transportation and flips the rubber blocks during storage to prevent the roller from directly contacting the ground, thereby reducing the friction of the roller, extending the service life, and reducing repair and maintenance costs.
[0025] like Figure 1 , Figure 2As shown, the rolling tooling includes a push-pull assembly, a rolling assembly, a protection assembly and a counter; the push-pull assembly includes a push-pull rod 4 and a mounting frame, and the mounting frame is located at the bottom of the push-pull rod 4; the rolling assembly includes a roller, and the roller is rotatably mounted on the mounting frame; the protection assembly includes a fixed bracket 9, a support block and an auxiliary wheel 5, the top of the fixed bracket 9 is rotatably mounted on the push-pull assembly, the support block is mounted on the fixed bracket 9, and the auxiliary wheel 5 is mounted on the mounting frame and located on the other side of the fixed bracket 9. The counter is mounted on the mounting frame to detect the number of rotations of the roller.
[0026] The push-pull assembly includes a push-pull rod 4 and a mounting frame, wherein the push-pull rod 4 is arranged on the top of the mounting frame to realize the push-pull operation of the entire device. A rolling assembly is provided on the mounting frame, including a roller, and the roller is rotatably mounted on the mounting frame to realize the free rotation of the roller. The protection assembly consists of a fixed bracket 9, a support block and an auxiliary wheel 5. The top of the fixed bracket 9 is rotatably connected to the push-pull assembly. By arranging the support block on the fixed bracket 9, it plays a role in protecting the roller to prevent the roller from contacting the ground in a non-working state and causing wear or indentation. The auxiliary wheel 5 is installed on the mounting frame and is located on the other side of the fixed bracket 9, which can provide support during transportation and facilitate the movement of the tooling. The counter is installed on the mounting frame and uses magnetic induction to detect the number of rotations of the roller.
[0027] The side of the roller pressing tool is provided with auxiliary wheels 5. When transporting, the roller is lifted off the ground by tilting the push-pull rod 4, and supported by the auxiliary wheels 5 to avoid bumping and damage to the roller during transport. At the same time, the other side of the auxiliary wheel 5 of the roller pressing tool is provided with a fixed bracket 9 and a support block (rubber block 8). After the tool is used, the fixed bracket 9 is flipped to the lower side by tilting the push-pull rod 4, and then the push-pull rod 4 is reset to make the roller press against the support block with a certain elasticity to avoid indentation damage when the roller is placed. Therefore, the roller is protected by the auxiliary wheels 5 and the support blocks located on the opposite sides, reducing the bumping, friction and indentation damage of the roller 1 during transport and storage, ensuring the quality of rolling, extending the service life, and reducing the cost of repair and maintenance.
[0028] The rolling tool can detect the number of rolling circles of the roller in real time during rolling by means of a counter set on the mounting frame, thereby accurately counting the number of rolling times, avoiding the inaccuracy of manual control, ensuring product quality, avoiding secondary rework, and improving work efficiency.
[0029] The mounting frame includes a bearing plate and a mounting plate, the push-pull rod 4 is arranged on the upper part of the bearing plate, the mounting plate is arranged on the lower part of the bearing plate, and the roller is rotatably mounted on the bottom of the mounting plate. Figure 1As shown, the mounting frame is composed of a bearing plate and a mounting plate. The push-pull rod 4 is fixed on the upper part of the bearing plate. The bearing plate is used to transmit the push-pull force. The mounting plate is located at the lower part of the bearing plate and serves as the mounting base of the roller. The roller is mounted on the bottom of the mounting plate through a rotating shaft to achieve contact and rolling operation with the floor leather. The structure between the bearing plate and the mounting plate ensures the stability of the device.
[0030] A shaft sleeve is provided at the bottom of the mounting plate, and the rolling assembly further comprises a roller shaft 2, which is inserted into the shaft sleeve and rotatably mounted with the shaft sleeve, and the roller is mounted on the roller shaft 2.

The roller assembly includes a roller shaft 2, which is inserted into the sleeve and rotatably connected to the sleeve through a bearing or a sliding fit to ensure the smooth operation of the roller. The roller is installed on the roller shaft 2. The roller 1 and the roller shaft 2 have high precision requirements, with a precision of 1mm. The roller 1 and the roller shaft 2 have good matching, which improves the smoothness of direction control and pressure consistency during use.
[0031] The mounting plates and rollers are provided in multiple numbers, each mounting plate is located between two rollers, and limit bolts 3 are installed at both ends of the roller shaft 2 to fix the rollers. The rolling range can be adjusted by adjusting the number and width of the rollers to a range of (400-600) mm, and the rolling pressure can be adjusted by adjusting the roller weight to a pressure of (300-600) N according to demand.
[0032] In this embodiment, Figure 1 , Figure 3 As shown, there are two mounting plates and three rollers, and each mounting plate is located between two rollers to form a multi-roller linkage rolling structure. Limiting bolts 3 are installed at both ends of the roller shaft 2 to fix the position of the roller and prevent the roller from axial movement when rotating. The multi-roller design can improve the rolling efficiency and ensure sufficient rolling of the floor leather. At the same time, the setting of the limiting bolts 3 can achieve a stable fixation of the roller and ensure the stable operation of the device.
[0033] The fixing bracket 9 includes a connecting rod and a bottom plate, wherein the bottom plate is located at the bottom of the connecting rod, and the connecting rod and the bottom plate form a ∠-shaped structure, and the supporting block is a rubber block 8, and the rubber block 8 is mounted on the bottom plate. Figure 2 , Figure 5 As shown, the fixed bracket 9 is composed of a connecting rod and a bottom plate, the connecting rod and the bottom plate are in a ∠-shaped structure, and the connecting part can be folded. The support block is installed on the bottom plate. The support block is made of rubber, which has good elasticity and buffering effect.

The snap ring is clamped on the rotating shaft and can realize relative rotation. A snap 10 is provided on the side of the push-pull rod 4. The snap 10 includes a sleeve and a snap ring. The sleeve is sleeved and fixed on the push-pull rod 4. The snap ring is installed on the sleeve. The fixed bracket 9 can be clamped on the snap ring of the snap 10 after rotating upward. During construction, the fixed bracket 9 is folded up and clamped at the snap 10. When idle, the fixed bracket 9 is put down, and the rubber block 8 is placed under the roller 1.
[0035] like Figure 2 , Figure 4 As shown, an auxiliary plate is provided on one side of the mounting frame, the auxiliary plate is at a predetermined angle to the push-pull rod 4, and the auxiliary wheel 5 is rotatably mounted on the bottom of the auxiliary plate. The auxiliary plate is provided to provide a mounting base for the auxiliary wheel 5, so that the auxiliary wheel 5 contacts the ground when the tooling is tilted and transported, thereby assisting the movement and positioning of the tooling.
[0036] The counter can be an externally purchased magnetic induction digital display counter 6, which includes a magnetic induction sensor and a magnetic mark (magnet). The magnetic induction sensor can be a Hall effect sensor or other magnetic field sensor. The mounting frame also includes a counting board, which is mounted on one side of the mounting board, the magnetic induction sensor is mounted on the counting board, and the magnetic mark is mounted on the roller. The counter also includes a display (digital display screen): used to display the number of turns detected. The digital display screen is connected to the sensor and can display the number of rotations of the roller 1 in real time, helping the operator to monitor the number of rolling turns of the operation. The display is mounted on the carrier plate to facilitate real-time data reading. When the roller rotates, the magnetic mark rotates accordingly. When passing through the magnetic induction sensor, an induction signal is generated and transmitted to the counter, so as to achieve accurate counting of the number of rotations of the roller, provide data support for the control of the number of rolling times, thereby effectively controlling the degree of pressing of the floor leather, avoiding excessive or insufficient rolling, and improving the construction quality. In addition, the number of rolling turns of floor leather of different models can be counted, which plays a role in operation specification, achieving the purpose of reducing costs, improving the quality of finished products, and making the operation standards reasonable and well-founded.
[0037] In summary, the roller pressing tooling has a simple structure, multiple application scenarios, easy processing, low investment cost, good product quality, high precision, easy operation, light weight, good safety performance, durability, and improves production efficiency and product quality.
