This utility model discloses an online adhesive removal device, belonging to the field of automated label application technology for packaging. The utility model includes a drive assembly, a control assembly, a decontamination roller assembly, a decontamination agent atomizing assembly, and a frame assembly. The decontamination roller assembly is mounted on the frame assembly, with its decontamination surface facing the application drum ring surface. The drive assembly is mounted on the decontamination roller assembly and drives the decontamination surface to rotate. The decontamination agent atomizing assembly and the control assembly are both mounted on the decontamination roller assembly. The decontamination agent atomizing assembly sprays the decontamination agent onto the decontamination surface. The control assembly controls the automatic operation of the entire device. In practical use, the decontamination surface utilizes appropriate friction to automatically remove adhesive residue from the label application drum. This solves the technical problem of adhesive residue easily forming on the application drum ring surface, affecting its normal operation.

This invention discloses a die-cutting device for corrugated cardboard box production, comprising: a vacuum pump, a dust suction nozzle, a water pump, and an atomizing nozzle. During the production of corrugated cardboard boxes, a large amount of debris and dust is generated during die-cutting. The vacuum pump is activated to draw the dust from the die-cutting area inside the casing into a connecting pipe via the dust suction nozzle, where it is then transported to a dust collection box for centralized storage. Simultaneously, heavier debris automatically falls into a collection box. Since the water pump draws water from a water tank and delivers it through pipes to the atomizing nozzle on the inner wall of the collection box, the atomizing nozzle sprays water onto the bottom of the collection box, effectively wetting the debris that falls into the collection box. This not only prevents secondary dispersion of debris but also allows dust not sucked in by the vacuum pump to fall into the collection box, thus achieving more comprehensive dust and debris collection and protecting the working environment.

This invention provides a powder tanker unloading system, including a temporary storage tank. The upper part of the temporary storage tank is connected to a feed hose, and the upper end of the temporary storage tank is connected to a filter shell. The filter shell has an exhaust port connected outwards, and a dust filter element is installed inside the filter shell. The lower end of the temporary storage tank is connected downwards to a discharge pipe. A unloading section is located at the lower end of the powder tanker. A discharge pipe, detachably connected to the free end of the feed hose, is located at the bottom of the unloading section. An air injection pipe is arranged around the unloading section. The discharge pipe has a strip-shaped feed inlet extending along its length within the unloading section. Multiple high-pressure air blowing pipes, extending into the unloading section and facing the strip-shaped feed inlet, are arranged inwards from the air injection pipe. The free end of each high-pressure air blowing pipe is open and inclined towards the sealing plug. This invention utilizes high-speed airflow to propel the powder quickly unloading, eliminating the need to maintain a high-pressure environment inside the tank, resulting in lower unloading energy consumption and greater safety.

The utility model discloses a portable high altitude oil feeder relates to oil feeder technical field, including support seat and drive assembly, one side fixedly connected with oil storage tank in the middle part of support seat, the other side of oil pump chamber is established in the middle part of support seat, the inner bottom wall fixedly connected with drive assembly of oil pump chamber, the utility model discloses through the setting of the fixed connection of sealing cover and the threaded connection of oil injection pipe, protection cover and oil storage tank effectively enhances the overall sealing property of oil storage tank, avoids lubricating oil leakage, reduces grease waste and protects the operating environment, prevents foreign matter pollution lubricating oil simultaneously, guarantees lubrication effect, through the setting of observation window, handle type oil injection nozzle, hose and connecting piece, and personnel can master oil quantity in real time, avoids midway oil cut, handle type oil injection nozzle promotes holding stability, and hose adapts multi -angle operation demand, and the precision and efficiency of high altitude oil injection operation are improved greatly, and the operation risk is reduced.

This utility model discloses a metal door and window cutting device. A mounting plate is fixedly installed on the upper surface of the workbench. A bracket is slidably installed above the mounting plate, and a cutting disc is located below the bracket. Limiting rods slide through both sides of the cutting disc. A pressure plate is fixedly installed at the bottom of the limiting rods, and a limiting plate is threadedly fixed to the top of the limiting rods. A support rod is fixedly installed on one side of the limiting plate, and a lever is rotatably installed at the top of the support rod. A column is fixedly installed on the upper surface of the bracket, and the top of the column is rotatably connected to the lower surface of the lever. Two symmetrically arranged dust suction pipes are slidably installed on the top of the bracket. Through the limiting rods, pressure plate, lever, and dust suction pipes, the two sides of the cutting seam can be further fixed during cutting, preventing saw blade deviation and reducing cut quality. Simultaneously, it ensures dust removal and elimination of irritating odors during cutting of door and window components of different thicknesses.
