Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and particularly relates to a self-propelled winding machine. Background Art

[0002] With the rapid development of the modern logistics and packaging industries, as an efficient packaging winding machine, the winding machine is widely used in the packing and fixing of various goods. By winding the film on the surface of the goods, the winding machine can effectively prevent the goods from shifting, being damaged or scattered during transportation, thereby improving the transportation safety and efficiency. Especially in large warehouses, logistics centers and manufacturing factories, the use of the winding machine greatly reduces the time and cost of manual packaging and improves the overall production efficiency.

[0003] Most of the existing self-propelled winding machines adopt an in-built battery design, and the battery pack is usually located at the bottom or inside of the winding machine. Although this design ensures the integrity and stability of the winding machine to a certain extent, it also brings many inconveniences. First of all, the disassembly and replacement process of the battery pack requires manual operation. The operator needs to perform cumbersome disassembly and installation work at the bottom of the winding machine, which is not only time-consuming and laborious, but also increases the labor intensity. Secondly, due to the large weight of the battery pack and its low position, the operator needs to bend down or squat frequently when replacing the battery, and long-term operation is likely to cause fatigue and operation errors. In addition, the replacement process of the battery pack may also be restricted by the structure of the winding machine, further increasing the complexity of the operation.

[0004] Therefore, a self-propelled winding machine is proposed. Summary of the Invention

An accelerator for adjusting the movement speed of the winding machine is also provided on the vehicle body.

[0008] Further, the battery loading and unloading mechanism includes a third motor, and the third motor is fixedly installed on the bottom surface of the chassis. The output end of the third motor is fixedly connected with a threaded rod. A connecting frame is threadedly connected to the surface of the threaded rod. The top surface of the connecting frame is fixedly connected with an L-shaped rod. The horizontal part of the L-shaped rod is higher than the inner bottom surface of the chassis.

A first gear is fixedly sleeved on the surface of the output shaft. A second gear is fixedly sleeved on the surface of the rotating shaft.

[0010] Further, the main structure of the column is composed of aluminum profiles and is used to support the film seat. A first motor for controlling the lifting of the film seat is installed at the bottom of the column. A chain connected to the output end of the first motor is installed inside the column, and the lifting of the film seat is realized through the movement of the chain. A lifting ring for equipment hoisting and transportation is installed at the top of the column. A second motor for driving the rotational movement of the film seat is installed in the upper part of the column. The output shaft of the second motor is connected with a third gear for transmitting power to the film seat. A roller for supporting the winding film reel is installed inside the film seat. A film fixing rod for fixing the winding film to prevent it from loosening during the winding process is installed on the roller. A first heavy-duty connector for realizing the electrical and mechanical connection between the film seat and the column is installed in the upper part of the column.

Through the operation of the battery loading and unloading mechanism, the dead battery pack on the surface of the vehicle body is disassembled and automatically carried to the surface of the chassis. Subsequently, the fully charged battery pack is sent into the interior of the vehicle body for installation through the battery loading and unloading mechanism, so that the battery pack is docked with the Anderson plug, and the replacement of the battery pack can be completed. By setting the battery loading and unloading mechanism, the present invention realizes the rapid replacement of the battery pack. The battery loading and unloading mechanism can automatically pull out or push in the battery pack from under the vehicle body, avoiding the cumbersome operation of the traditional winding machine relying on manual handling of the battery pack. The operator does not need to bend down or squat down, reducing the labor intensity and improving the efficiency of battery replacement.

[0013] 2. Since the battery pack can be quickly replaced, the winding machine does not need to stop for a long time to charge when the battery runs out of power. It only needs to replace the fully charged battery pack to continue working. This design significantly reduces the downtime of the equipment and improves the working efficiency of the equipment, especially suitable for scenarios that require long-term continuous operation.

[0020] As Figures 1 to 8 shown, a self-propelled winding machine includes: a vehicle body 1, a column 20 is fixedly installed on the vehicle body 1, a film seat 21 for installing and outputting a winding film is installed on the column 20, a battery pack 11 for providing a replaceable power source for the winding machine is installed on the vehicle body 1, and a battery loading and unloading mechanism 14 for quickly replacing the battery pack 11 is also installed on the vehicle body 1. The surface of the vehicle body 1 is fixedly connected with a chassis 15, and the battery loading and unloading mechanism 14 is installed on the chassis 15. A column fixing hinge 4 is provided between the column 20 and the vehicle body 1, and a first heavy-duty connector 31 is provided between the film seat 21 and the column 20. An Anderson plug 10 is provided between the battery pack 11 and the electrical board 8.

[0021] A handle 2 for an operator to control the movement of the winding machine is fixed on the side of the vehicle body 1. A limit block 3 for restricting the movement range of the film seat 21 is installed on the top of the vehicle body 1. Lifting wheels 5 and edge-finding wheels 6 for the movement and positioning of the winding machine are installed at the bottom of the vehicle body 1. A housing 7 for protecting the internal mechanical and electrical structures of the vehicle body is covered outside the vehicle body 1. A toolbox 9 for storing tools and accessories is fixed on the side of the vehicle body 1. A transport column mounting bracket 12 for the installation and fixation of the column 20 is fixed on the top of the vehicle body 1. An accelerator 13 for adjusting the movement speed of the winding machine is also provided on the vehicle body 1.

[0022] When the battery pack 11 needs to be replaced, the fully charged battery pack 11 is carried by the chassis 15 and moved to the right side of the vehicle body 1. Through the operation of the battery loading and unloading mechanism 14, the dead battery pack 11 on the surface of the vehicle body 1 is disassembled and automatically transported to the surface of the chassis 15. Subsequently, the fully charged battery pack 11 is sent into the interior of the vehicle body 1 through the battery loading and unloading mechanism 14 for installation, so that the battery pack 11 is docked with the Anderson plug 10, and the replacement of the battery pack 11 can be completed.

[0023] The battery loading and unloading mechanism 14 includes a third motor 141, and the third motor 141 is fixedly installed on the bottom surface of the chassis 15. The output end of the third motor 141 is fixedly connected to a threaded rod 142. A connecting frame 143 is threadedly connected to the surface of the threaded rod 142. The top surface of the connecting frame 143 is fixedly connected to an L-shaped rod 1410. The horizontal portion of the L-shaped rod 1410 is higher than the bottom surface of the inner wall of the chassis 15. A chute 144 is formed through the bottom surface of the chassis 15, and the inner wall of the chute 144 is slidably connected to the L-shaped rod 1410. A slide rod 1412 is fixedly connected to the bottom surface of the chassis 15, and the slide rod 1412 is slidably connected to the connecting frame 143. An adjustable limit assembly is provided at the end of the L-shaped rod 1410. More specifically, by driving the threaded rod 142 to rotate through the third motor 141, under the action of the thread, the connecting frame 143 will be driven to slide along the surface of the slide rod 1412, thereby pulling the L-shaped rod 1410 to move to the left. The L-shaped rod 1410 will extend under the vehicle body 1. Subsequently, the adjustable limit assembly operates and rotates 90 degrees. The third motor 141 controls the threaded rod 142 to rotate in the reverse direction, and the L-shaped rod 1410 can be pulled to move to the right. Cooperating with the adjustable limit assembly, the battery pack 11 can be pulled, so that the Anderson plug 10 on its surface is disconnected from the vehicle body 1. Finally, the battery pack 11 with depleted power is carried to the surface of the chassis 15. Subsequently, the position of the chassis 15 is adjusted. By operating another third motor 141, it is controlled that another L-shaped rod 1410 carries a new battery pack 11 to move to the left, so that the battery pack 11 reaches under the vehicle body 1, and the Anderson plug 10 is docked with the vehicle body 1, and the replacement of the battery pack 11 can be completed.

[0024] The adjustable limit assembly includes a rotating shaft 146. A baffle 145 is fixedly connected to the end of the rotating shaft 146. A fourth motor 147 is fixedly installed on the surface of the L-shaped rod 1410. The output end of the fourth motor 147 is fixedly connected to an output shaft 148. A first gear 149 is fixedly sleeved on the surface of the output shaft 148. A second gear 1411 is fixedly sleeved on the surface of the rotating shaft 146. It should be noted that in the normal state, the baffle 145 is flush with the horizontal portion of the L-shaped rod 1410, and does not affect the L-shaped rod 1410 reaching under the battery pack 11 installed on the surface of the vehicle body 1. When the L-shaped rod 1410 reaches under the battery pack 11, the motor shaft 148 is driven to rotate through the fourth motor 147, thereby driving the first gear 149 to rotate, and then driving the second gear 1411 meshed with it to rotate, so as to control the rotating shaft 146 to rotate, and then drive the baffle 146 to rotate to the vertical state. When the L-shaped rod 1410 moves to the right, it will drive the baffle 146 to contact the left side surface of the battery pack 11, thereby pulling the battery pack 11 and disassembling it.

[0025] The main structure of the column 20 is composed of aluminum profiles 23 and is used to support the film seat 21. A first motor 25 for controlling the lifting of the film seat 21 is installed at the bottom of the column 20. A chain 24 connected to the output end of the first motor 25 is installed inside the column 20. The lifting of the film seat 21 is achieved through the movement of the chain 24.

Buttons 33 for controlling the operation of the film seat 21 are installed on the surface of the housing 32. A film seat bracket 34 for supporting the structure of the film seat 21 is installed at the upper part of the column 20. A second heavy-duty connector 35 for realizing the electrical connection between the film seat 21 and the vehicle body 1 is installed on the film seat bracket 34. An electric control box 22 for controlling the overall operation of the equipment is installed on the side of the column 20.

[0026] A directional wheel 16 is provided on the left side of the bottom surface of the chassis 15, a universal wheel 17 is provided on the right side of the bottom surface of the chassis 15, a ground brake 18 is further provided at the bottom of the chassis 15, and a handle 19 is fixedly connected to the side surface of the chassis 15. By grasping the handle 19 and cooperating with the rolling of the directional wheel 16 and the universal wheel 17, the chassis 15 can be quickly moved, making the handling of the new and old battery packs 11 more convenient. When replacing the battery pack, the chassis 15 can be limited by the ground brake 18 to prevent it from shaking, thus facilitating the replacement of the battery pack 11.

[0027] In summary: When the battery pack needs to be replaced, the fully charged battery pack is carried by the chassis and moved to the right side of the vehicle body. Through the operation of the battery loading and unloading mechanism, the dead battery pack on the surface of the vehicle body is disassembled and automatically carried to the surface of the chassis. Subsequently, the fully charged battery pack is sent into the interior of the vehicle body for installation through the battery loading and unloading mechanism, enabling the battery pack to be docked with the Anderson plug, and thus completing the replacement of the battery pack. By setting the battery loading and unloading mechanism, the present invention realizes the rapid replacement of the battery pack. The battery loading and unloading mechanism can automatically pull out or push in the battery pack from under the vehicle body, avoiding the cumbersome operation of relying on manual handling of the battery pack in traditional winding machines. The operator does not need to bend down or squat down, reducing the labor intensity and improving the efficiency of battery replacement. Since the battery pack can be quickly replaced, the winding machine does not need to stop for a long time to charge when the battery runs out of power, and only needs to replace the fully charged battery pack to continue working. This design significantly reduces the downtime of the equipment and improves the working efficiency of the equipment, especially suitable for scenarios that require long-term continuous operation.
