Description

Technical Field

[0001] The utility model relates to the field of screening devices, in particular to a material conveying and screening device for a packaging machine. Background Art

[0002] Material screening refers to screening out impurities or unqualified materials from materials. Most existing screening devices use automatic screening, such as weight or size detection screening, which can not only ensure the quality of screening but also has high efficiency. However, some materials cannot be automatically screened, such as whether the packaging bag is sealed after the material is packaged, so manual screening is the only option. During manual screening, the staff needs to place the materials on the screening table or table for screening.

[0003] However, in the prior art, the height of the screening table is fixed, which results in some staff members not being able to use it when they change shifts, thus affecting the screening efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a material conveying and screening device for a packaging machine.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a material conveying and screening device for a packaging machine, comprising a conveying frame, one side of the conveying frame is fixedly connected to a support plate, the upper end of the support plate is fixedly connected to a support rod, the right side of the support rod is fixedly connected to a connecting plate, the interior of the connecting plate is provided with a threaded hole, the interior of the support rod is slidably connected to an adjusting rod, the front side of the adjusting rod is provided with a scale block, the right side of the adjusting rod is fixedly connected to a stabilizing plate, the interior of the stabilizing plate is movably connected to a rotating rod, the exterior of the rotating rod is fixedly connected to a limiting ring, and the lower end of the rotating rod is fixedly connected to a screw rod.

[0006] Preferably, the upper end of the adjusting rod is fixedly connected to a fixing seat, clamping holes are provided on both sides of the fixing seat, a mounting block is movably connected inside the fixing seat, and the upper end of the mounting block is fixedly connected to a screening table.

[0007] Preferably, a slide groove is provided inside the mounting block, a slider is slidably connected inside the slide groove, a clamping block is fixedly connected to one side of the slider, a telescopic rod is provided on the right side of the clamping block, and a spring is sleeved on the outside of the telescopic rod.

[0008] Preferably, the internal thread of the connecting plate is matched with the external thread of the screw rod.

[0009] Preferably, the sliding block slides in the sliding groove through the clamping block, the telescopic rod and the spring.

[0010] Preferably, the number of the clamping blocks is two groups, and they are symmetrically arranged about the center line of the mounting block.

[0011] By adopting the above technical solution, the rotating rod is rotated, and the rotating rod drives the screw rod to rotate. With the cooperation of the limit ring, the internal thread of the connecting plate and the stabilizing plate, the adjusting rod slides inside the supporting rod, and the screening table is raised to adjust its height. Similarly, by rotating the rotating rod in the opposite direction, the screening table can be lowered, and the setting of the scale block can enable the staff to remember the height that suits them, which is convenient for adjustment when using the screening table next time. The stabilizing plate, rotating rod, limit ring, screw rod cooperate with the connecting plate and the threaded holes inside it to make the adjusting rod rise and fall, and then the height of the screening table can be adjusted to meet the use needs of different staff members and increase the screening efficiency.

[0012] By adopting the above technical solution, the card block is pushed, and the card block causes the telescopic rod to compress the spring, so that the card block slides out from the inside of the card hole, pulling the screening table upward, and the mounting block slides along the inner wall of the fixed seat to complete the disassembly of the screening table. Similarly, during installation, the mounting block is slid along the inside of the fixed seat, and when the card block reaches the position of the card hole, the spring rebounds to cause the telescopic rod to push the card block into the card hole to complete the installation of the screening table. During the movement of the card block, the slider slides inside the slide groove, and the cooperation of the slider and the slide groove can increase the stability of the card block during movement. The screening table can be loaded and unloaded by the card block, the telescopic rod, the spring and the card hole, and can be replaced when it is damaged, while the difficulty of replacement can also be reduced.
