Description

Technical Field

[0001] This utility model relates to the technical field of bag trolleys, and in particular to bag trolleys. Background Technology

[0002] The trolley wrapping machine is used as an auxiliary machine in the wire and cable processing to wrap the metal surface of wires and cables with film. If the film is used up during the wrapping process, it needs to be manually braked and then replaced. If the staff does not notice that the film is used up, the machine will run idle, which may result in some wires and cables not being wrapped with film, causing rework. It is not very convenient. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a bag-carrying machine.

[0004] This utility model discloses a bag-carrying machine, comprising a base plate, a fixed support, locking bolts, a lifting platform, a controller, a support arm, and a first guide wheel. The fixed support is located at the top of the base plate, and the locking bolts are mounted on the fixed support. A lifting assembly is located between the lifting platform and the fixed support. A controller is mounted on the lifting platform. A support arm is mounted on the lifting platform, and a first guide wheel is mounted at the top of the support arm. The machine also includes a guide wheel assembly, a drive assembly, and a clamping assembly. A buffer alarm assembly is mounted on the lifting platform. The film roll is unwound via the drive assembly. The film passes through the buffer alarm assembly and multiple sets of guide wheel assemblies, and wraps around one end of the first guide wheel to secure the electrical wires and cables. When the film is used up, the buffer alarm assembly sounds an alarm to remind the staff that the film is finished and should be replaced promptly.

[0005] Preferably, the lifting assembly includes a lead screw, a threaded connecting block, and a throttle. The lead screw is slidably installed inside the fixed support and is threadedly connected to the threaded connecting block. Two sets of throttles are symmetrically arranged on the outer wall of the threaded connecting block. When adjusting the height of the lifting platform, the operator raises the lifting platform and then rotates the threaded connecting block, thereby adjusting the position of the threaded connecting block on the outer wall of the lead screw. After the adjustment is completed, the bottom end of the threaded connecting block contacts the top end of the fixed support, and the locking bolt is rotated to tighten the lead screw, thereby locking the lead screw and realizing the adjustment of the height of the lifting platform.

[0006] Preferably, the drive assembly includes a motor, a disc, a lead screw, a top-mounted column, and a fastening nut. The motor is located at the bottom of the lifting platform, and a rotating shaft is located at the output end of the motor. The rotating shaft extends above the lifting platform and connects to the bottom of the disc. A lead screw is fixedly installed at the top of the disc, and a top-mounted column is fitted onto the outer wall of the lead screw. The fastening nut is threadedly connected to the lead screw. The film roll is fitted onto the outside of the lead screw and placed on the disc. After the top-mounted column is fitted onto the outside of the lead screw, the fastening nut is threadedly connected to the lead screw, thereby tightening the film roll with the cooperation of the top-mounted column. The motor is then started to unwind the film roll.

[0007] Preferably, the guide wheel assembly includes a second guide wheel, a second lead screw, and a second nut. Multiple sets of strip-shaped openings are provided on the lifting platform. A second guide wheel is rotatably mounted on the top of the fixed seat, and a second lead screw is mounted on the bottom of the fixed seat. The second lead screw passes through the strip-shaped opening and is threadedly connected to the second nut. Inserting the second lead screw into the corresponding strip-shaped opening and threading it with the second nut completes the installation of the second guide wheel. The diaphragm crosses around multiple sets of second guide wheels and also around the first guide wheel, improving flexibility.

[0008] Preferably, the buffer alarm assembly includes a pole, a light bar, a movable block, a third guide wheel, springs, and a sensor. Two sets of poles are installed at the top of the lifting platform, and two sets of light bars are fixedly installed between the two sets of poles. A movable block is slidably mounted on each set of light bars, and a third guide wheel is rotatably mounted between the two sets of movable blocks. Two sets of springs are mounted on the outer side of each set of light bars, with the movable block positioned between the two sets of springs. A sensor is installed at the top of the base plate, positioned between the two sets of poles. The four sets of springs work together to position the two sets of movable blocks in the middle of the two sets of light bars. When the diaphragm passes over one side of the third guide wheel, the tension of the diaphragm moves the third guide wheel, causing the bottom movable block to move away from the sensor. When the diaphragm is no longer pulled by the diaphragm, the third guide wheel, with the cooperation of multiple sets of springs, returns the movable block to the middle of the two sets of poles. The sensor detects the moved movable block and issues an alarm, improving buffering performance and convenience.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the film roll is unwound by the drive assembly, the film passes through the buffer alarm assembly and multiple sets of guide roller assemblies and wraps around one end of the first guide roller to wind the wire and cable. When the film is used up, the buffer alarm assembly will sound an alarm to remind the staff that the film is used up and should be replaced in time. Attached Figure Description
