Abstract
Description
Technical Field
[0001] This utility model belongs to the field of packaging machine technology, specifically, it relates to a side horizontal packaging machine corner protection device. Background Technology
[0002] A paper corner protector forming machine is a machine that specializes in producing paper corner protectors. It is generally composed of paper guiding, gluing, forming, cutting, automatic stacking and other devices and some accessories. It can complete all the processes of paper corner protector manufacturing. Paper guiding and gluing are completed by several sets of rollers, which guide and apply glue at the same time. The forming part is composed of several sets of "V" shaped pressure rollers that cooperate with each other to press the glued paper strips into right angles.
[0003] Patent CN119190812A discloses a single-sided six-bullet-cell vertical corner protector machine. A translation mechanism drives a movable frame to translate along the X-axis, adjusting the horizontal position of the corner protector gripping frame. This allows the corner protector gripping mechanism to be positioned within the corner protector compartments, where it retrieves the corner protectors. Because multiple corner protector compartments are provided, different sizes of paper corner protectors can be placed within them. The gripping mechanism can then be moved to different compartments to retrieve the corresponding sizes of paper corner protectors. This method eliminates the need to stop the machine to change paper corner protectors, significantly improving work efficiency.
[0004] However, in the technical solution of the aforementioned patent, the corner guard gripping mechanism can only grip taller goods. When the goods are lower, the single corner guard arm has space requirements below when it extends, which restricts the movement of the single corner guard arm, making it impossible to grip lower goods. Traditional corner guard machines cannot meet the usage requirements and have certain limitations. Utility Model Content
[0005] The purpose of this utility model is to provide a side horizontal packing machine corner protection device to solve the technical problem in the prior art that the corner protection gripping mechanism has space requirements below when the single arm of the corner protection is extended, making it unable to grip lower goods.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A side horizontal packing machine corner protection device includes a packing machine frame, a long plate, a conveyor line, and a corner protection compartment; a truss is fixedly connected to the long plate; a linear guide rail is fixedly connected to the side of the truss; two movable frames are slidably connected to the linear guide rail via sliders; an extension arm is fixedly connected to the lower surface of each movable frame; a corner protection gripping and pushing mechanism is fixedly connected to the bottom of the extension arm.
[0008] Furthermore, there are two long plates, both of which are arranged horizontally on both sides of the middle part of the packaging machine frame.
[0009] Furthermore, the conveyor line is positioned on the packaging machine frame below the long plate.
[0010] Furthermore, the corner guard compartment is located on the side of the conveyor line away from the packaging machine frame.
[0011] Furthermore, a rack is fixedly connected to the upper part of the truss; a DC geared motor is fixedly installed on the upper part of the movable frame; and a gear is driven at the output end of the DC geared motor.
[0012] Furthermore, the extension arm is an aluminum profile bracket.
[0013] Furthermore, a crash barrier is fixedly connected to the lower part of the extension arm; a limit switch is fixedly connected to the crash barrier.
[0014] The beneficial effects of this utility model are:
[0015] 1. This utility model inverts the movable frame and connects it to the linear slide rail, and sets the corner guard gripping and pushing mechanism at a low position near the corner guard compartment. The movable frame and the corner guard gripping and pushing mechanism are connected by an extension arm, so that when the DC geared motor drives the gear to rotate, it can cooperate with the rack and pinion to drive the corner guard gripping and pushing mechanism to move horizontally. Because its integrated structure adopts an inverted structure compared with the prior art, it can be placed in a very small space above the conveyor line, which can serve the needs of gripping lower goods, thus improving adaptability. In addition, since the extension arm is an aluminum profile bracket, the height position of the corner guard gripping and pushing mechanism can be adjusted at will, thereby adapting to and meeting more packaging needs.
[0016] 2. This utility model utilizes the combination of limit switches and anti-collision plates to control the start and stop of the DC geared motor, thereby effectively preventing the moving frames from colliding with each other and with the goods, providing safety for the equipment.
