Description

Rotating reflective film pasting device

Technical Field

The invention belongs to the technical field of rotating body processing, and more specifically, relates to a rotating body reflective film pasting device.

Background Art

In recent years, cars have become popular as a common means of transportation for people to travel, and more and more cars are appearing on the road. As a result, there are more and more traffic accidents, and the prevention and treatment of traffic accidents are receiving more and more attention. In order to cope with the inconvenience caused by the increasing number of vehicle congestion on the road, as well as the rugged terrain and changeable road conditions, there is a practice of installing anti-collision guardrails on both sides of the road in the prior art. The structure of anti-collision guardrails is diverse. Anti-collision guardrails equipped with rotating bodies are becoming more and more widely used because they can well release the energy of the impact. For example, the Chinese patent application number 201610384329.1, "A road traffic guardrail capable of buffering and absorbing impacts" with an application date of 2016.05.30, discloses an anti-collision guardrail, which uses a rotating body and a connecting piece between the rotating bodies to absorb the kinetic energy of the colliding car, which can greatly reduce the damage to the car itself due to the impact.

The rotating body of the anti-collision guardrail is generally affixed with reflective stickers, which can also be called reflective films. Reflective films are a kind of retro-reflective materials that can be directly applied. They can play a certain warning role when they are set on the rotating body of the anti-collision guardrail. In the prior art, the reflective films on the rotating body are generally manually rotated by the rotating body, and then the reflective films are attached around the rotating body. The weight of a single rotating body is generally 2-3kg. The process of attaching reflective films is relatively laborious and the work efficiency is not high, which affects the continuous production of the rotating body. The Chinese patent application number is 201811249710.2, and the application date is 2018.10.25, "A reflective film posting device for a pole", which includes a mounting box and an arc-shaped ring frame. The mounting box is provided with an arc-shaped surface, and the arc-shaped surface and the arc-shaped ring frame cooperate to form a mounting ring for being mounted on the pole. The arc-shaped surface is provided with a through hole for the reflective film to pass through. The mounting box is provided with a first rotating shaft for fixing the reflective roll and a second rotating shaft for fixing the backing paper. The first rotating shaft and the second rotating shaft can be rotatably mounted in the mounting box, and the first rotating shaft and the second rotating shaft rotate in opposite directions to separate the reflective film from the backing paper. The reflective film posting device can realize the posting of reflective film by one person, thereby improving the posting efficiency of reflective film. However, the reflective film posting device is suitable for electric poles, and the problem of posting reflective film is solved from the outer contour of the electric pole. The outer contour of the electric pole is uniform, and the diameter is not much different, while the outer contour of the rotating body is an uneven cylinder with depressions, and the outer diameters of rotating bodies of different types and models will vary greatly, which is not suitable for posting reflective film on the surface of the rotating body.

Another example is the Chinese patent application number: 201420252616.3, application date: 2014.05.18, "A portable device for pasting reflective paper on a rotating rotor", which includes a small DC motor, a roller fixed on the motor shaft, and reflective paper arranged on the roller, a buckle for fixing the reflective paper is arranged on the roller, a handle is fixed on the motor, and a circuit and a sliding button for controlling the motor are arranged on the handle. The reflective paper pasting device achieves the purpose of pasting reflective paper without affecting the operation of the auxiliary machine, reduces the start-up and shutdown process of the auxiliary machine, not only saves time, but also reduces costs, greatly improves the efficiency of high-speed dynamic balancing test, and provides the possibility for online monitoring of the auxiliary machine in rotation; however, the device is not suitable for pasting reflective film on the surface of a rotating body. The rotating body only needs to rotate one circle to complete the pasting of a circle of reflective film. After the pasting of the reflective film is completed, it is necessary to switch to the next rotating body to continue the pasting of the next reflective film. The above device cannot complete the pasting of reflective film and the rotation and replacement of the rotating body.

Although these exemplary embodiments are described in sufficient detail to enable those skilled in the art to implement the present invention, it should be understood that other embodiments can be implemented and various changes can be made to the present invention without departing from the spirit and scope of the present invention. The following more detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but is only for the purpose of illustrating and not limiting the description of the characteristics and features of the present invention, so as to propose the best mode for performing the present invention and to enable those skilled in the art to implement the present invention. Therefore, the scope of the present invention is limited only by the appended claims.

The following detailed description of the present invention and example embodiments may be better understood in conjunction with the accompanying drawings, in which elements and features of the present invention are identified by reference numerals.

Example 1

The rotating body on the anti-collision guardrail is generally set as a cylinder with at least one groove on it. In order to prevent the reflective film from falling off after being posted and the reflective film from being damaged during use, which would damage the warning function of the reflective film, the reflective film needs to be posted in the groove.

At present, our company mainly produces three specifications of rotating bodies, which are concentric rings with grooves on the outer diameter. The first type has an inner diameter of 140±100mm, an outer diameter of 220±10mm, and a height of 480mm; the second type has an inner diameter of 140±10mm, an outer diameter of 350±10mm, and a height of 480mm; the third type has an inner diameter of 140±10mm, an outer diameter of 350±10mm, and a height of 240mm.

In the process of pasting the reflective film on the rotating body, the rotating body needs to be sleeved on the device of the present application, and then the reflective film is pasted in the groove of the rotating body through rotation.

As shown in Fig. 1 to Fig. 3, a rotating reflective film pasting device of this embodiment includes a support assembly 100 and a rotating assembly 200, and the support assembly 100 and the rotating assembly 200 are rotatably connected. The support assembly 100 is used to provide support and a stable foundation for the entire device, and the rotating assembly 200 is used to carry the rotating body and make the rotating body rotate. One end of the reflective film is pasted on the rotating body, and the rotating body is driven to rotate by the rotation of the rotating assembly 200. When the rotating body rotates one circle, the reflective film also surrounds the rotating body, and then the reflective film is pasted to complete the reflective film pasting work. The whole process takes a short time and does not require too much manpower. The work process is relatively labor-saving and efficient.

The support assembly 100 includes a support frame 110 and a mounting seat 120. The support frame 110 is composed of four support columns and a storage platform 111 connected to the four support columns. The storage platform 111 is a steel product. The four support columns are steel pipes welded to the storage platform 111. The storage platform 111 has three main functions. The first is to stabilize the support frame 110 so that the support columns will not shake. The second is to provide a connection point between the mounting seat 120 and the support frame 110. The mounting seat 120 is welded to the storage platform 111, which is simple and practical. The third is that when the reflective film is pasted on the rotating body or when the pasting is completed, the rotating body can be placed on the storage platform 111 to observe the shape and size of the rotating body and the pasting of the reflective film. The mounting seats 120 are respectively arranged on both sides of the storage platform 111. The mounting seats 120 are bearing seats. The top of the bearing seats is welded to the storage platform 111. The center position of the bearing seat is the first mounting hole 121, and the center line of the first mounting hole 121 coincides. In addition to the support frame 110 for supporting the entire device, the support assembly 100 is also provided with a first mounting hole 121 on the support frame 110. There are more than two first mounting holes 121, which are clearance-matched with the connecting rod 210. In order to allow the connecting rod 210 to pass through the first mounting hole 121 conveniently, the center lines of the first mounting hole 121 need to coincide with each other to prevent the first mounting hole 121 from getting stuck on the connecting rod 210.

The rotating assembly 200 includes a connecting rod 210, a rotating roller 220 and a rotating wheel 230. The connecting rod 210 is a cylindrical rod that passes through the first mounting hole 121 in the middle of two concentric rings. The two are clearance-fitted. The connecting rod 210 can rotate in the first mounting hole 121. One end of the connecting rod 210 is connected to the rotating roller 220, and the other end is connected to the rotating wheel 230. The rotating roller 220 is a cylindrical rod with a diameter of 125 mm, which can rotate along with the rotation of the connecting rod 210. The outer side of the rotating roller 220 is sleeved with a rotating body. The center of the rotating wheel 230 is a hollow cylinder, and the hollow position is a through hole. The outer sides of both ends are provided with a ring larger than the diameter of the central through hole. Four rods are connected between the two rings. By turning the four rods, the rotation of the rotating wheel 230 can be completed, and the connecting rod 210 and the rotating roller 220 can be driven to rotate. The connecting rod 210 of the rotating assembly 200 is used to support the rotating roller 220 and the rotating wheel 230, and at the same time passes through the first mounting hole 121 on the support frame 110 to provide rotation stability for the rotating assembly 200. The rotating roller 220 is outerly connected to the rotating body, and the rotating body is driven to rotate by the rotation of the rotating roller 220, so as to complete the posting of reflective film on the outside of the rotating body. The rotating wheel 230 has a through hole in the center and a wheel on the outside. The rotating roller 220 is rotated by manually turning the rotating wheel 230.

Example 2

In actual use, when large-scale operations are required and manual labor cannot meet the output requirements, the completely manual method is not suitable for production and improves production efficiency.

And because the sizes of the rotating bodies are different, the masses of the rotating bodies are also different to a certain extent. In order to adapt to different anti-collision guardrails, the size of the hollow center of the rotating body will change. In order to adapt to rotating bodies of different sizes and masses to a certain extent, the rotating body rotates with the rotating roller 220 during the rotation process. A second mounting hole 221 is opened on the surface of the rotating roller 220, and an adjusting component 400 is arranged in the second mounting hole 221. The height of the pressing block 410 is controlled by the elastic member 420 on the adjusting component 400, so that the pressing block 410 fits the inner wall of the hollow center of the rotating body and presses the rotating body. Due to the pressure of the pressing block 410, the rotating body will rotate with the rotation of the rotating roller 220.

As shown in FIGS. 4-6 , a rotating reflective film pasting device of this embodiment further includes a driving component 300 and an adjusting component 400 based on the embodiment 1.

The driving assembly 300 includes a motor 310 and a control box 320. One end of the motor 310 has an output shaft, which is connected to the through hole of the rotating wheel 230, and a key is used to connect the two. Since the motor 310 needs to be frequently controlled during use, the speed of the motor 310 cannot be too fast. On the one hand, a too fast speed affects the posting work of the reflective film, and on the other hand, frequent startup and deceleration will also damage the motor 310 itself. The more suitable motor 310 is a medium-speed motor or a low-speed motor. Since the error caused by manual control of the motor is large, it is necessary to use a PLC control box 320 for regulation, and the motor that adapts to the PLC control box 320 should be a stepper motor or a servo motor. If a DC motor or a high-speed motor is used, it needs to be used with a reducer, and the reducer is also controlled by the PLC control box 320, so that the device can be better operated and used.

The control box 320 is a PLC control box 320, which is electrically connected to the motor 310, and controls the motor 310 through the PLC program, thereby controlling the rotation of the rotating roller 220. In order to control the rotation and stop of the output shaft of the motor 310, if it is controlled only by a switch, its delay and error are large. By electrically connecting the PLC control box 320 to one end of the motor 310, the motor 310 is electrically controlled by the PLC, and the automatic rotation of the device is realized, which saves the equipment operation time and greatly improves the production efficiency.

The adjustment component 400 includes a top pressure block 410, an elastic member 420 and a top pressure rod 430. One end of the elastic member 420 is connected to the top pressure block 410, and the other end is connected to the rotating roller 220. The elastic member 420 can perform telescopic movement, and the elastic member 420 will not undergo permanent deformation. The top pressure block 410 follows the elastic member 420 to perform reciprocating movement on the movement trajectory of the elastic member 420. In the selection process of the elastic member 420, the above conditions only need to be met. In this embodiment, a spring is preferably used as the elastic member 420. The top pressure block 410 as a whole has a protrusion at the center position, and the edge in the direction of the sleeve rotating body is lower than the center position. At the same time, the protrusion of the top pressure block 410 and the edge of the top pressure block 410 are smoothly transitioned through a curve. When the rotating body is sleeved, the maximum distance between the protrusion on the surface of the top pressure block 310 in the non-working state and the rotating roller 220 is 30 mm. If the rotating roller 220 has only a protrusion on the surface and a smooth transition is not made using a curve, it is difficult for the rotating body to be sleeved on the rotating roller 220. The use of a curve for transition reduces the resistance of the rotating body to be sleeved on the rotating roller 220, and the top pressure block 410 will not scratch the inner wall of the rotating body, thereby avoiding damage to the inner wall of the rotating body and extending the service life of the top pressure block 410. Since the sizes of the rotating bodies are different, the masses of the rotating bodies are also different to a certain extent. In order to adapt to different anti-collision guardrails, the size of the hollow center of the rotating body will change. In order to adapt to rotating bodies of different sizes and masses to a certain extent, the rotating body rotates with the rotating roller 220 during the rotation process. A second mounting hole 221 is opened on the surface of the rotating roller 220, and an adjusting component 400 is arranged in the second mounting hole 221. The height of the pressing block 410 is controlled by the elastic member 420 on the adjusting component 400, so that the pressing block 410 fits against the inner wall of the hollow center of the rotating body and presses the rotating body. Due to the pressure of the pressing block 410, the rotating body rotates with the rotation of the rotating roller 220.

One end of the push rod 430 is connected to the rotating roller 220, and the other end is a free end, which is located directly below the push block 410. During the working process or due to manual error, the push block 410 may be pressed into the second mounting hole 221, which will cause the adjustment component 400 to lose its adjustment function. In order to avoid this phenomenon, a push rod 430 is provided at the lower end of the push block 410, and the distance between the top surface of the free end of the push rod 430 and the inner surface of the rotating roller 220 is d1. The minimum thickness of the edge of the push block 410 is d2, and d1 is less than d2. At this time, the push block 410 will not be pressed into the second mounting hole 221.
