Description

Technical Field

[0001] The present application relates to a packaging machine. Background Art

[0002] There is a weighing platform under the material outlet of the packaging machine. On the one hand, it carries the packaging bags and materials, and on the other hand, it weighs to control the weight of the materials. For example, according to the weight, there can be different packages of 25 kg and 40 kg. Different packaging bags have different lengths, so the height of the weighing pan needs to be adjusted to adapt to different packages. Utility Model Content

[0003] The purpose of the present application is to provide a packaging machine capable of adjusting the height of a weighing pan.

[0004] To this end, according to the technical solution of the present application, a packaging machine includes a weighing pan assembly, wherein the weighing pan assembly is configured to move up and down, and the packaging machine also includes a driving mechanism for driving the weighing pan assembly to move up and down.

[0005] Wherein, the driving mechanism includes a slider which moves up and down, and the slider is connected to the scale pan assembly.

[0006] In one embodiment, the driving mechanism includes a stepping motor and a lead screw coaxially fixed to the stepping motor, and the slider is mounted on the lead screw and moves along the lead screw.

[0007] In one embodiment, the driving mechanism comprises a cylinder assembly, and the slider is connected to a pneumatic piston of the cylinder assembly.

[0008] In one embodiment, the driving mechanism comprises a hydraulic assembly, and the slider is connected to a hydraulic piston of the hydraulic assembly.

[0009] Furthermore, the weighing pan assembly includes a weighing pan and a weighing pan support for fixing the weighing pan, and the driving mechanism is connected to the weighing pan support.

[0010] Wherein, the weighing pan assembly is configured to move up and down along the weighing pan guide rail.

[0011] This application can set the weighing pan height according to the packaging bag size and product quality to ensure smooth packaging of different products. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 This is a schematic diagram according to an embodiment of the present application, showing a drive mechanism and a scale pan assembly.

[0014] 10 packaging machines, 20 weighing pans, 30 weighing pan supports, 40 weighing pan guide rails, 50 stepper motors, 60 screw rods, 70 sliders, 80 support seats, 100 racks DETAILED DESCRIPTION

[0015] The specific implementation of the present application is described below with reference to the accompanying drawings.

[0016] In the present application, the terms "upper", "lower", "higher" and "lower" refer to directions in a generally vertical direction.

[0017] Figure 1 The packaging machine 10 shown has a scale pan 20 for weighing the packaged products.

[0018] See also Figure 2 Typically, the weighing pan 20 is mounted on a weighing pan support 30 and moves up and down along a weighing pan guide rail 40 together with the weighing pan support 30 .

[0019] In order to drive the weighing pan 20 to move up and down, the packaging machine further includes a driving mechanism coupled to the weighing pan 20 .

[0020] Reference Figure 2 The driving mechanism is mounted on a frame 100 of the packaging machine 10. In one embodiment, the driving mechanism includes a stepping motor 50, a screw rod 60 coaxially fixed to the stepping motor 50, and a slider 70 sleeved on the screw rod 60. The slider 70 is threadedly engaged with the screw rod 60. A support seat 80 is provided at the end of the screw rod 60 to fix the screw rod 60.

[0021] The slider 70 is fixed to the scale pan support 30 and drives the scale pan support 30 to move, thereby moving the scale pan 20 .

[0022] The stepper motor 50 operates to rotate the screw rod 60 , and under the action of the thread, the slider 70 can move up and down driven by the screw rod 60 .

[0023] In another embodiment, the driving mechanism comprises a cylinder assembly and a slider connected to a pneumatic piston of the cylinder assembly. The slider is fixedly connected to the scale pan support.

[0024] In yet another embodiment, the driving mechanism comprises a hydraulic assembly and a slider connected to a hydraulic piston of the hydraulic assembly. Similarly, the slider is fixedly connected to the scale pan support.

[0025] In the above description, the details of the technical solution of the present application are explained. However, those skilled in the art will appreciate that the present application is not limited to the specific details listed in the above embodiments, but may vary within the scope defined by the claims.
