Description

Technical Field

[0001] The utility model relates to the technical field of opening and closing of horizontal packaging machines, in particular to an opening and closing module group of a servo trolley of a horizontal packaging machine. Background Art

[0002] The horizontal packaging machine is an automatic composite film packaging machine independently developed for the diversity of packaging materials and the adjustability of packaging bag types. It is a fully automatic food packaging equipment that integrates operations such as bag taking, bag feeding, opening and closing, and loading. The horizontal packaging machine adopts a filling method of making bags first and then unloading materials. The unloading port can directly discharge materials from the bottom of the packaging bag to avoid dust. For extremely fine and easily raised powder particles, a dust collector and suction device can be added to the upper seal. At the same time, it uses a horizontal seal to reinforce the sealing, ensure the sealing of the seal, and extend the shelf life of the product. In the existing technology, the horizontal packaging machine can basically meet daily use needs, but in the actual production process, it is found that the traditional device is driven by an ordinary motor, resulting in the trolley opening and closing stroke and timing during the operation of the equipment cannot be adjusted, affecting the practicability of the device; therefore, it is necessary to design a servo trolley opening and closing module for the horizontal packaging machine. Utility Model Content

[0003] The utility model aims to provide a servo trolley opening and closing module for a horizontal packaging machine, so as to solve the problem that the traditional device is driven by an ordinary motor, resulting in that the trolley opening and closing stroke and timing during the operation of the equipment cannot be adjusted, thus affecting the practicality of the device.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a servo trolley opening and closing module of a horizontal packaging machine, comprising a module base plate, a top bearing seat, a first deep groove ball bearing, a first thrust ball bearing, a lead screw, a connecting block, a support seat, a lifting slider and a fixed pin shaft. The top of one side of the module base plate is fixedly connected with a top bearing seat, and a fixing plate is arranged on an adjacent side of the module base plate. The first deep groove ball bearing and the first thrust ball bearing are respectively sleeved in the top bearing seat, and the first deep groove ball bearing and the first thrust ball bearing are both sleeved on the top of the lead screw. A connecting block is arranged on the lead screw, and the connecting block is cooperatively connected to the lead screw through a ball nut embedded and installed internally. A support seat is arranged at the bottom of the connecting block, a lifting slider is fixedly installed on one side of the support seat, and a fixed pin shaft is sleeved in the lifting slider. The bottom end of the lead screw is fixedly connected with a coupling, and the coupling is cooperatively connected to the output end of the servo motor.

[0005] As a further technical solution of the utility model, a rocker is rotatably connected to the fixed pin shaft, and one end of the rocker is rotatably connected to a rocker arm.

[0006] As a further technical solution of the utility model, the servo motor is fixed to the bottom of the motor base, and the motor base is fixedly installed on the bottom of the module base plate.

[0007] As a further technical solution of the present utility model, a bottom bearing seat is fixedly installed at the bottom of one side of the module base plate, and a second deep groove ball bearing and a second thrust ball bearing are respectively sleeved in the bottom bearing seat.

[0008] As a further technical solution of the present utility model, both the second deep groove ball bearing and the second thrust ball bearing are cooperatively sleeved on the bottom end of the lead screw.

[0009] As a further technical solution of the present utility model, a photoelectric support is provided on one side of the module base plate, and a proximity switch is provided on the photoelectric support.

[0011] The servo car opening and closing module of the horizontal packaging machine provided by the present utility model has the advantages that: the opening and closing structure of the car is connected by a rocker arm. During operation, the lead screw is driven to rotate by a servo motor. Through the mutual cooperation of the lead screw and the ball nut embedded inside the connecting block, the connecting block and the support seat are driven to move up and down along the direction of the lead screw. During the moving process, the bottom end of the rocker is driven to move up and down by a fixed pin shaft, and then the car is driven to perform the opening and closing process by the rocker arm on the rocker. During the opening and closing process, the proximity switch arranged on the photoelectric support is used for limiting and regulating. When the servo motor rotates and the lifting slider moves to the top proximity switch, the servo motor will reverse to drive the lifting slider to move down until it moves to the bottom proximity switch and then rotates forward again to realize the rising action of the lifting slider, which is convenient for regulating the stroke and timing of the car opening and closing, and improves the practicability of the device.
