Description

Technical Field

[0001] The utility model belongs to the technical field of pearl cotton processing, in particular to a pearl cotton slotting machine. Background Art

[0002] Pearl cotton, also known as polyethylene foam cotton, is a new type of environmentally friendly packaging material. It is composed of countless independent bubbles produced by physical foaming of low-density polyethylene grease. It has many advantages such as waterproof and moisture-proof, shockproof, soundproof, heat-insulating, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc. It also has good chemical resistance and is an ideal substitute for traditional packaging materials. In the production and processing of pearl cotton, it is usually necessary to groove its surface. In order to facilitate the groove of pearl cotton, a pearl cotton groover is generally used;

[0003] The existing document with publication number CN220481961U discloses a pearl cotton slotting machine, comprising: a bottom plate, a placement seat installed on the top of the bottom plate, a placement plate arranged inside the placement seat, a motor arranged on the top of the placement plate, a drill bit driven and connected at the bottom of the motor, an adjustment component arranged on the outside of the motor for adjusting the slotting position of the drill bit, and a movable component arranged between the placement plate and the placement seat for moving the placement plate;

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The pearl cotton slotting machine mentioned above has a placement seat installed on the top of its bottom plate, and a placement plate is provided inside the mounting seat, and the pearl cotton is placed by the placement seat and the placement plate, but it lacks a structure for turning over the pearl cotton, which makes it inconvenient to slot multiple surfaces of the pearl cotton;

[0006] 2. The above-mentioned pearl cotton slotting machine has fixed plates connected to both sides of the outer end of the placement plate, and a limit plate is arranged between the two fixed plates. One side of the outer end of the limit plate is rotatably connected to a push rod through a bearing, and one side of the outer end of one of the fixed plates is provided with a through hole threadedly connected to the push rod. The limit plate is driven to clamp the pearl cotton through the threaded connection between the push rod and the through hole. However, since the pearl cotton itself is prone to deformation, the external force of the limit plate on the pearl cotton is too large, causing the pearl cotton to deform, affecting the grooving accuracy of the pearl cotton.

[0007] To this end, we provide a pearl cotton slotting machine to solve the above-mentioned problems. Utility Model Content
