Description

Technical Field

[0001] This utility model belongs to the field of foam processing equipment, and in particular relates to a foam stabilization cutting device. Background Technology

[0002] Foam is a material made by foaming plastic particles and can be used for product packaging. The produced foam is often quite large and needs to be cut to meet specific customer size requirements.

[0003] Existing foam cutting equipment requires the foam to be cut to be placed horizontally on a conveyor belt and pushed forward. When the foam passes through the cutting blade, it will be cut into two parts. However, existing cutting equipment cannot stabilize the foam when it passes through the cutting blade. Under the cutting force of the cutting equipment, the foam may shake up and down or even move around. For example, in Chinese utility model patent with publication number CN208289989U, a new type of foam cutting machine is disclosed, in which the upper part of the cutting wheel is exposed above the conveyor belt. This structure cannot provide vertical restraint for the foam when it passes through the cutting wheel, and cannot guarantee the stability and accuracy of the cutting. Utility Model Content

[0004] The purpose of this invention is to provide a stable foam cutting device, which aims to solve the technical problem that the stability and accuracy of foam cutting cannot be guaranteed in the existing technology.

[0005] To achieve the above objectives, this utility model provides a foam stabilizing cutting device, comprising: a frame; a conveyor belt disposed on the frame, the upper surface of the conveyor belt horizontally supporting and conveying the foam forward; a rotating shaft rotatably disposed on the frame and located above the conveyor belt, the axis of the rotating shaft being arranged in the left-right direction; a cutting blade disposed on the rotating shaft, the cutting blade being perpendicular to the rotating shaft, the rotating shaft being configured to drive the cutting blade to rotate synchronously; and a pressure cylinder sleeved on the rotating shaft, the pressure cylinder being coaxially disposed with the rotating shaft and being able to rotate freely relative to the rotating shaft, the outer diameter of the pressure cylinder being smaller than the outer diameter of the cutting blade, and when the foam passes under the cutting blade, the outer surface of the pressure cylinder adhering to the upper surface of the foam.

[0006] Optionally, the distance between the rotating shaft and the upper surface of the conveyor belt is adjustable.

[0008] Optionally, a bearing is provided inside the pressure cylinder, the inner ring of the bearing is sleeved on the rotating shaft, and the outer ring of the bearing abuts against the inner ring of the pressure cylinder.

[0009] Optionally, a pressure bar is provided on the frame, the pressure bar is horizontally positioned, and the pressure bar can fit against the upper surface of the foam on the conveyor belt.

[0010] Optionally, the distance between the pressure bar and the upper surface of the conveyor belt is adjustable.

[0011] Optionally, two conveyor belts are provided, both of which are mounted on the frame and have a gap between them, and the bottom of the cutting blade can be inserted into the gap.

[0012] Optionally, the frame is provided with baffles on the opposite sides of the two conveyor belts.

[0013] Optionally, the surface of the conveyor belt is provided with a texture to increase friction.

[0014] Compared with the prior art, the above-mentioned one or more technical solutions provided in the embodiments of this utility model have at least one of the following technical effects:

[0015] During processing, the foam can be placed horizontally on a conveyor belt. The conveyor belt moves the foam closer to the cutting blade. When the foam contacts the cutting blade, the rotating blade cuts the foam to obtain the desired foam size. During the cutting process, the pressure cylinder remains in contact with the upper surface of the foam, preventing the cutting blade from applying cutting force that could cause the foam to vibrate or shift position, thus ensuring cutting stability and improving cutting accuracy.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0030] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a foam 300 stable cutting device, including a frame 100, a conveyor belt 200, a rotating shaft 110, a cutting blade 400, and a pressure cylinder 500.

[0031] The conveyor belt 200 is mounted on the frame 100. The upper surface of the conveyor belt 200 can horizontally support the foam 300 and transport the foam 300 forward. The rotating shaft 110 is rotatably mounted on the frame 100 and located above the conveyor belt 200. The axis of the rotating shaft 110 is set in the left-right direction. The cutting blade 400 is mounted on the rotating shaft 110 and is perpendicular to the rotating shaft 110. The rotating shaft 110 is configured to drive the cutting blade 400 to rotate synchronously. The pressure cylinder 500 is sleeved on the rotating shaft 110. The pressure cylinder 500 is coaxial with the rotating shaft 110 and can rotate freely relative to the rotating shaft 110. The outer diameter of the pressure cylinder 500 is smaller than the outer diameter of the cutting blade 400. When the foam 300 passes under the cutting blade 400, the outer surface of the pressure cylinder 500 is in contact with the upper surface of the foam 300.

[0032] Understandably, during processing, foam 300 can be placed horizontally on conveyor belt 200. Conveyor belt 200 can move foam 300 towards the cutting blade 400. When foam 300 contacts cutting blade 400, the rotating cutting blade 400 can cut foam 300 to obtain the desired foam 300 size. During the cutting process of cutting foam 300 by cutting blade 400, pressure cylinder 500 can always be in contact with the upper surface of foam 300 to prevent cutting force from the cutting blade 400 from causing foam 300 to vibrate or shift position, thereby ensuring cutting stability and improving cutting accuracy.

[0033] It should be noted that the movement of foam 300 toward the cutting blade 400 can be achieved entirely by the friction of the conveyor belt 200, or by the push of the operator.

[0034] In some embodiments of this invention, the distance between the rotating shaft 110 and the upper surface of the conveyor belt 200 is adjustable. When cutting foam 300 of different thicknesses, the height of the rotating shaft 110 relative to the upper surface of the conveyor belt 200 can be adjusted so that the outer surface of the pressure cylinder 500 can just fit against the upper surface of the foam 300. Specifically, the position adjustment of the rotating shaft is a conventional structure in the art; for example, it can be achieved through a lead screw and nut mechanism or a gear and rack mechanism.

[0035] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, two pressure cylinders 500 are provided, and the two pressure cylinders 500 are respectively located on both sides of the cutting blade 400. By providing two pressure cylinders 500, both sides of the foam 300 can be limited by the pressure cylinders 500 during the cutting process, which can further improve the stability of the foam 300 during the cutting process.

[0036] like Figure 2As shown, in some embodiments of this utility model, a bearing 510 is provided inside the pressure cylinder 500. The inner ring of the bearing 510 is sleeved on the rotating shaft 110, and the outer ring of the bearing 510 abuts against the inner ring of the pressure cylinder 500. By providing the bearing 510, the pressure cylinder 500 can rotate freely relative to the rotating shaft 110. This is because during the cutting process of the cutting blade 400, the rotational speed of the rotating shaft 110 is often higher than the cutting speed of the foam 300, while the rotational speed of the pressure cylinder 500 needs to be consistent with the moving speed of the foam 300.

[0037] In some embodiments of this utility model, a pressure bar (not shown in the figure) is provided on the frame 100. The pressure bar is horizontally positioned and can conform to the upper surface of the foam 300 on the conveyor belt 200. Specifically, the pressure bar can be located behind the cutting blade 400. During the forward movement of the foam 300, the pressure bar can restrict the rear of the foam 300, enabling the foam 300 to be stably conveyed forward. The pressure bar can be designed to rotate relative to the frame 100. Specifically, the pressure bar can be a driven roller, rotating synchronously with the foam 300 as it moves; or it can be designed as a driving roller, whereby setting the rotation speed of the pressure bar to match the moving speed of the conveyor belt 200 allows for simultaneous application of a forward force to both the upper and lower surfaces of the foam 300.

[0038] Furthermore, in some embodiments of this utility model, the distance between the pressure bar and the upper surface of the conveyor belt 200 is adjustable to accommodate the processing of foam 300 of different thicknesses.

[0039] Reference Figure 1 and Figure 2 In some embodiments of this utility model, two conveyor belts 200 are provided, both of which are mounted on the frame 100 and have a gap 600 between them. The bottom of the cutting blade 400 can be inserted into the gap 600. The gap 600 allows for a wider range of height adjustment of the rotating shaft 110. In addition, the gap 600 facilitates material discharge, preventing the cut foam 300 debris from remaining on the conveyor belts 200.

[0040] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the frame 100 is provided with baffles 120 on the opposite sides of the two conveyor belts 200. The horizontal distance between the two baffles 120 can be adapted to the width of the foam 300. The foam 300 is conveyed on the conveying channel formed by the two baffles 120, which is not easy to deviate and can improve the dimensional accuracy of the foam 300 after cutting.

[0041] In some embodiments of this utility model, in order to enable the conveyor belt 200 to have greater friction based on the foam 300, a texture for increasing friction can be provided on the surface of the conveyor belt 200.

[0042] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
