Description

Technical Field

[0001] The utility model relates to an improved invention of a bag-feeding packaging machine, in particular to an improved invention of a shrink cup top material device. Background Art

[0002] The shrink cup is one of the feeders used for bag-packing machines. It is characterized by its strong pressure resistance and is suitable for materials that are not afraid of squeezing. The weight can be automatically measured by adjusting the ejection device. The mold will cut and squeeze the material according to the change of the cam from large to small, and then feed it to the shrinkage cup. The ejection shaft driven by the cylinder will eject the material that exceeds the standard weight. During the transmission of the cylinder, vibration is prone to occur and the noise is relatively loud. At the same time, liquid drips during the ejection process, affecting hygiene. Utility Model Content

The upper end of the ejecting shaft can be matched and extended into the lower port of the shrinkage cup, and the lower end of the ejecting shaft is fixed in the liquid collecting tank of the guide plate. The guide plate is installed on the guide shaft, and the guide shaft can be raised and lowered and slidably arranged on the guide seat, and the guide seat is fixed on the base. The corresponding guide plate is transmission-connected to the power source, and the power source is a servo motor. The guide plate is also equipped with a stroke control system.

[0005] The travel control system includes a controller and a photoelectric eye. The photoelectric eye senses the travel of the guide plate, and the photoelectric eye and the power source are both connected to the controller signal.

[0006] The lower end of the ejecting shaft is fixedly penetrated on the frustum, and the frustum is fixed on the bottom of the liquid collecting tank.

[0007] The output shaft of the servo motor is fixedly connected to one end of the swing arm, and a connecting rod is hinged between the other end of the swing arm and the guide plate.

[0008] The beneficial effect of the utility model is that the improved shrink cup ejecting device drives the swing arm and the connecting rod to move back and forth through the servo motor, thereby driving the ejecting shaft to eject vertically, and the ejecting stroke is controlled by a photoelectric eye, and the liquid dripping from above is discharged through the guide plate. The mechanical transmission is stable and reliable, which makes the working noise smaller, and the dripping liquid is collected and discharged, which is more hygienic. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0010] Figure 1 It is a structural schematic diagram of the utility model.

[0011] Figure 2 It is a partial enlarged view of the utility model. DETAILED DESCRIPTION

[0012] The accompanying drawings show the structure of the utility model, and the following further describes its relevant details in conjunction with the accompanying drawings. Figure 1-2 The shrink cup ejecting device comprises a base 1 and a power source 2. The base 1 is provided with a guide plate 3 and an ejecting shaft 4 which can be raised and lowered. The upper end of the guide plate 3 is provided with a liquid collecting trough 5, and the liquid collecting trough 5 is equipped with a drainage interface 6. The drainage interface 6 can be connected to the catheter for external discharge. The upper end of the ejecting shaft 4 can be matched and extended into the lower port of the shrink cup. The lower end of the ejecting shaft 4 is fixed in the liquid collecting trough 5 of the guide plate 3. The guide plate 3 is installed on a guide shaft 7, and the guide shaft 7 can be raised and lowered and slidably arranged on a guide seat 8. The guide seat 8 is fixed on the base 1. The corresponding guide plate 3 is transmission-connected with the power source 2. The power source 2 is a servo motor. The guide plate 3 is also equipped with a stroke control system.

[0013] The working principle of the utility model is that the servo motor drives the guide plate 3 and the ejection shaft 4 to rise and fall, the ejection shaft 4 extends into the lower port of the contraction cup to eject the material with excessive gram weight, and the dripping liquid flows into the liquid collecting groove 5 of the guide plate 3 through the ejection shaft 4 and is discharged from the discharge port. The guide shaft 7 and the guide seat 8 cooperate with each other to support and guide the guide plate 3, so that the rising process of the ejection shaft 4 is more stable. At the same time, the stroke control system adjusts the stroke of the guide plate 3 and the ejection shaft 4 to adapt to the ejection of materials with different gram weights.

[0014] As a further improved specific implementation method, the travel control system includes a controller and a photoelectric eye 9. The photoelectric eye 9 is installed on a bracket. The photoelectric eye senses the travel of the guide plate 3, and the photoelectric eye 9 and the power source 2 are both connected to the controller signal. The photoelectric eye transmits the travel signal to the controller, and the controller then controls the power source 2 to adjust the travel. The controller is preferably a PLC.

[0015] As a further improved specific implementation, the lower end of the ejection shaft 4 is fixedly penetrated on the frustum 10, and the frustum 10 is fixed to the bottom of the liquid collecting tank 5. The frustum 10 supports the ejection shaft 4, and the conical surface can guide the liquid.

[0016] As a further improved specific implementation method, the output shaft of the servo motor is fixedly connected to one end of the swing arm 11, and a connecting rod 12 is hinged between the other end of the swing arm 11 and the guide plate 3. When working, the servo motor drives the swing arm 11 to swing back and forth, and then the connecting rod 12 drives the guide plate 3 to rise and fall.

[0017] In summary, the above is only the preferred embodiment of the present utility model and is not intended to limit the protection scope of the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
