Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to a novel adjustable bag placing device for tea packaging machines. Background Art

[0002] Currently, the quality of bulk tea is greatly affected by external factors, so most tea is packaged and stored to ensure the quality of the tea. Currently, the packaging process generally uses automated sealing equipment, that is, automatic packaging tea packaging machines are used to package tea to improve efficiency.

[0003] Existing tea packaging machines require packaging bags of different sizes and models due to different types of tea or different packaging quantities per bag. When using the bag placing device for placing bags of different sizes, the length of the bag placing device needs to be manually adjusted, which is inconvenient to replace. Utility Model Content

[0004] Therefore, in order to solve the above problems, the present invention proposes a novel adjustable bag placing device for tea packaging machine which can quickly and automatically adjust the length of the bag placing device and is quick and convenient to use.

[0005] To solve this technical problem, the utility model adopts the following solution: a new adjustable bag placing device for a tea packaging machine, comprising a controller, an encoder, a control panel, a first placing rack and a second placing rack, the first placing rack and the second placing rack cooperating to form a placing slot for placing tea packaging bags, and also comprising a forward and reverse motor, a gear and a rack, a first fixed seat and a second fixed seat are respectively provided on the rear sides of the first placing rack and the second placing rack, a slide rail is fixed on the first fixed seat, the second fixed seat is provided with a slide seat which is adapted to the slide rail on the first fixed seat and can slide back and forth on the slide rail, one end of the rack is fixedly connected to the second fixed seat or the slide and the rack is parallel to the slide rail, a gear is sleeved on the output end of the forward and reverse motor, the gear is meshed with the rack to drive the rack to move back and forth horizontally and then drive the second fixed seat or the slide to move back and forth horizontally to adjust the distance between the first placing rack and the second placing rack, the controller is connected via the encoder and controls the forward and reverse motor, and the control panel is connected to the input end of the controller.

[0006] As a further improvement, the forward and reverse motor is a servo motor or a stepper motor.

[0007] As a further improvement, one side of the width direction of the first placement rack and the second placement rack is respectively provided with an adjustable limiting plate and an adjusting rod for adjusting the width of the first placement rack and the second placement rack.

[0008] By adopting the above-mentioned technical solution, the beneficial effects of the utility model are as follows: by arranging matching slide rails and slide seats at the rear of the first placement rack and the second placement rack, and then arranging forward and reverse motors to drive the rack through the gear and then drive the second fixed seat or slide seat to move back and forth horizontally to adjust the distance between the first placement rack and the second placement rack, the electronic cam of the existing controller is used to control the travel length of the rack driven by the gear through the encoder, so that the user only needs to input the bag length of the tea packaging bag on the control panel, and the controller can control the forward and reverse motors to move the corresponding length to adjust the distance between the first placement rack and the second placement rack, so as to adapt to the placement of tea packaging bags of different sizes. When replacing tea packaging bags of different sizes, it is only necessary to input the bag length on the control panel to automatically adjust the length of the placement groove composed of the first placement rack and the second placement rack, thereby realizing rapid and automatic adjustment of the length of the bag placement device. It is fast and convenient to use and can be widely promoted and applied. BRIEF DESCRIPTION OF THE DRAWINGS
