Detailed Implementation

[0023] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Example 1: As Figures 1-4 As shown, a retractable AGV forklift includes a vehicle body and a control panel. The vehicle body includes a main base 1 and two support mechanisms. The two support mechanisms are symmetrically arranged on the upper part of the main base 1. A moving mechanism is provided at the lower part of the main base 1. The support mechanisms are also provided with a protective mechanism.

[0025] The support mechanism includes a frame 11 and a support arm 12. The frame 11 is fixedly mounted on the upper part of the vehicle body. The support arm 12 is fixedly connected to the frame 11 and has a recessed groove 13 at its upper end. The protection mechanism is located in the recessed groove 13 of the support arm 12. The protection mechanism consists of several limiters, which are evenly distributed in the recessed groove 13. The support arm 12 has an air supply channel 14 connected to the several limiters.

[0026] When transporting the rolled-up film into a cylindrical shape, the vehicle body is moved to a suitable external position by controlling the control panel. Then, the film is transported by external components and placed on the support arm 12 of the support mechanism. The recessed groove 13 can play a preliminary role in limiting the film and prevent it from rolling back and forth and causing instability.

[0027] Once the film is placed on the support arm 12, air can be supplied through an external air supply mechanism, such as an air pump, to activate the limiter. The limiter then limits the film roll on the support arm 12, thereby enabling convenient and effective positioning of the film roll during the transfer process and improving the safety of the transfer.

[0028] Correspondingly, when the transfer is completed or when it is not in use, the gas supply to the gas supply channel 14 is disconnected. At this time, the limiter will automatically reset to avoid obstructing the recessed groove 13 and affecting the preparation.

[0029] The limiter includes a first plug body 2, a limiting rod 21, and an elastic element 22. The support arm 12 has a stepped cavity 23 that matches the limiter and faces upward. The stepped cavity 23 is connected to the air supply channel 14. The first plug body 2 is slidably sealed in the stepped cavity 23. The limiting rod 21 is fixedly connected to the first plug body 2 and slides out of the stepped cavity 23. The elastic element 22 is located at the upper end of the first plug body 2 and is located in the stepped cavity 23.

[0030] The elastic element 22 is a spring and is sleeved on the limiting rod 21.

[0031] The connection port between the air supply channel 14 and the stepped cavity 23 is located on the lower side of the first plug body 2.

[0032] The end of the limiting rod 21 is equipped with a rubber ball.

[0033] The recessed groove 13 has an isosceles trapezoidal structure with its long side facing upwards.

[0034] When air is filled into the air supply channel 14 and injected into the corresponding stepped cavity 23, the first plug 2 in the stepped cavity 23 is pushed upward by the gas and gradually moves upward. At this time, the elastic element 22 contracts and the limiting rod 21 extends out of the stepped cavity 23 and gradually approaches the cylindrical film roll until the limiting rod 21 abuts against the film roll. At this time, the limiting rod 21 can no longer extend and move. Several limiters cooperate with each other to automatically form an arc-shaped limiting groove that fits the surface of the film roll to the maximum extent. The structure of the recessed groove 13 can produce a more effective limiting effect on the film roll, making it less likely to roll back and forth. It can also match film rolls with different diameters than the recessed groove 13, making it more flexible.

[0035] Of course, the gas supply channel 14 can also be used as a liquid delivery channel and change the gas into a liquid, thereby avoiding the problem that the limiting effect may be affected by the compressibility of the gas.

[0036] The rubber ball design prevents the limit rod 21 from directly and rigidly contacting the film roll, thus avoiding damage. At the same time, the rubber ball itself has a certain degree of elastic deformation, which allows it to fit the film roll better, increasing the contact area and thus enhancing the protective effect.

[0037] Example 2: As Figure 2 As shown, in a further improvement based on Embodiment 1, the protection mechanism also includes a support, which is located between the support arm 12 and the main body base 1. The support includes a liquid storage cylinder 3, a second plug 31, and a support rod 32. One end of the liquid storage cylinder 3 is hinged to the main body base 1. The second plug 31 is slidably sealed inside the liquid storage cylinder 3. The support rod 32 is fixedly connected to the second plug 31 and slides out of the liquid storage cylinder 3. The other end of the support rod 32 is hinged to the lower end of the support arm 12. The other end of the liquid storage cylinder 3 is connected to an external liquid storage container through a conduit. The conduit is equipped with an electrically controlled opening and closing valve. The support arm 12 and the upright frame 11 are connected by a motor rotation control.

[0038] Furthermore, in order to improve the convenience of loading and unloading, the support arm 12 can also be rotatably connected to the upright frame 11 via a motor. In this way, the height position of the support arm 12 can be adjusted according to the appropriate loading and unloading height of the production equipment, making it easier to place the film roll into the recessed groove 13 of the support arm 12. In order to reduce the load pressure on the motor and support, reduce the stress deformation of the components and the possibility of sudden drop due to component failure.

[0039] When the support arm 12 rotates to adjust its height and tilt, the liquid storage cylinder 3 and the support rod 32 are hinged to the main base 1 and the lower end of the support arm 12, respectively. The support rod 32 is slidably connected to the liquid storage cylinder 3 through the second plug 31. Therefore, when the support arm 12 flips, it will drive the support rod 32 to extend and retract, thereby forcing the second plug 31 to move inside the liquid storage cylinder 3 and push the hydraulic oil inside the liquid storage cylinder 3 through the conduit. The corresponding conduit is connected to the external liquid storage container. When the support arm 12 flips upward, the electrically controlled opening and closing valve opens to ensure that the components can move normally. After the support arm 12 lifts the film roll completely, the electrically controlled opening and closing valve closes and cuts off the pipeline, thereby limiting and blocking the second plug 31 and the support rod 32. This serves to assist in supporting the support arm 12 through the support rod 32, making the process of transferring the film roll safer and improving the stability of the equipment operation.

[0040] Example 3: As Figure 4 As shown, in a further improvement based on Embodiment 2, the main body base 1 is also provided with a liquid controller connected to the conduit. The liquid controller includes a housing 4, a switch post 41, and an electrically controlled telescopic rod. The switch post 41 is slidably sealed inside the housing 4. The switch post 41 has symmetrically opened annular grooves 42 on its side. The switch post 41 has a main liquid groove 43 in the middle that communicates with the two annular grooves 42. The main liquid groove 43 passes through the switch post 41 near the end of the conduit. The main liquid groove 43 is provided with a one-way liquid inlet valve 44 located between the two annular grooves 42. The side of the housing 4 is also provided with a bypass liquid pipe 45 that matches the annular grooves 42. The electrically controlled telescopic rod is embedded in the stand 11 and its output shaft extends into the housing 4 and is connected to the switch post 41.

[0041] In order to further improve the safety of feeding and discharging, protection is provided during the overturning movement of the support arm 12 to avoid accidents during overturning and reduce the overturning speed. When the support arm 12 is overturned upward, the electric telescopic rod is extended forward at this time and the ring groove 42 away from the conduit corresponds to the bypass liquid pipe 45. At this time, when the support arm 12 is overturned upward and the hydraulic oil is pulled upward through the second plug body 31, the hydraulic oil will be pumped into the housing 4 through the bypass liquid pipe 45, the corresponding ring groove 42 and the main liquid groove 43, and finally through the conduit into the liquid storage cylinder 3. Due to the existence of the one-way liquid inlet valve 44 in the main liquid groove 43, only the hydraulic oil is allowed to be transported from the side away from the conduit to the side close to the conduit. Therefore, when the support arm 12 is overturned upward to lift the material, the situation of accidental falling of the support arm 12 can be avoided, and the safety is improved.

[0042] When it is necessary to unload the material and overturn the support arm 12 downward, the output shaft of the electric telescopic rod is retracted at this time and pulls the on-off column 41, so that the ring groove 42 close to the conduit corresponds to the bypass liquid pipe 45. At this time, the bypass liquid pipe 45, the corresponding ring groove 42 and the main liquid groove 43 form a complete passage without the blockage of components or valve bodies. At this time, the support arm 12 can be overturned downward and the hydraulic oil can be squeezed out. Correspondingly, at this time, the electric telescopic rod can be controlled through the control panel to adjust the cross-sectional size of the pipeline connection between the corresponding ring groove 42 and the bypass liquid pipe 45, so as to realize the throttling effect, so as to reduce the overturning speed of the support arm 12 and avoid the accidental falling of the support arm 12, which is more beneficial to the safe operation of the equipment.

[0043] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical thought of the present application should be covered by the claims of the present application.
