Description

Technical Field

[0001] This utility model relates to the field of packaging product manufacturing technology, and in particular to an embossing core for packaging cushioning paper products. Background Technology

[0002] With the development of e-commerce, the express delivery industry has become one of the fastest-growing industries in recent years. Protecting products during express delivery is an important issue that companies have always needed to address. Bubble packaging is a common cushioning packaging method, mainly used to protect fragile or sensitive items from impact and pressure during transportation. Previous bubble packaging usually involved the use of foam materials (such as polyurethane) or bubble wrap, which expands in time when compressed to form a temporary filler, thereby providing shock absorption.

[0003] However, with the increasing awareness of environmental protection, my country is actively addressing plastic pollution, from restricting the use of plastic bags to banning single-use plastic products, and further refining legal responsibilities—all these efforts are being made vigorously and systematically. Bubble wrap is an environmentally friendly packaging material, primarily made of 100% recyclable and biodegradable kraft paper, suitable for packaging products weighing up to 10 kg. It has excellent cushioning and compression resistance, effectively protecting goods from damage during transportation. The size of the packaging box needs to be adjusted on-site according to the size of the transported goods. Providing embossing cores for packaging cushioning paper suitable for small-item express packaging is a pressing technical problem that needs to be solved in this field. Utility Model Content

[0004] The technical problem to be solved by this utility model is to design a stable, reliable, and easy-to-use embossing core for packaging cushioning paper products.

[0005] To solve the above-mentioned technical problems, this utility model provides an embossing machine core for packaging cushioning paper products, including a mounting frame and an embossing roller assembly disposed between the mounting frames; Transmission components are used to drive the rotation of the embossing roller assembly; The embossing roller assembly includes a first embossing roller and a second embossing roller arranged in parallel. The two ends of the first embossing roller and the second embossing roller are rotatably engaged with the mounting frame. Multiple annular embossing dies are fixedly arranged on the first embossing roller and the second embossing roller. Multiple embossing blocks are arranged on the outer side of the annular embossing dies so that when the packaging cushioning paper passes between the first embossing roller and the second embossing roller, the embossing blocks form indentations on the surface of the packaging cushioning paper.

[0006] Furthermore, the first embossing roller and the second embossing roller are provided with axially extending limiting grooves, and the inner sidewall of the annular die is provided with limiting blocks that are adapted to the limiting grooves. When the annular die is assembled, the limiting blocks are inserted into the limiting grooves to circumferentially limit the annular die, so that the annular die rotates synchronously with the first embossing roller and the second embossing roller.

[0007] Furthermore, the outer wall of the annular die is evenly distributed with multiple embossing blocks, so that when the packaging cushioning paper enters between the first embossing roller and the second embossing roller, the embossing blocks will press the packaging cushioning paper.

[0008] Furthermore, the transmission assembly includes a drive motor, a first gear that drives the drive motor, a second gear that meshes with the first gear, the second gear that drives one end of the first embossing roller, a third gear that is provided at the other end of the first embossing roller, and a fourth gear that meshes with the third gear that is provided at one end of the second embossing roller, so that the drive motor drives the first embossing roller and the second embossing roller to rotate in opposite directions.

The limiting components include a limiting plate, a locking block, and a pressure strip. A first mounting hole is provided at one end of the limiting plate, and a rectangular frame is provided at the other end of the limiting plate. The locking block is slidably engaged with the rectangular frame. A semi-circular hole of the limiting plate is provided on the rectangular frame, and a semi-circular hole of the locking block is provided that matches the semi-circular hole of the limiting plate, so that when the pressure strip fixes the locking block in the rectangular frame, the semi-circular hole of the limiting plate and the semi-circular hole of the locking block form a second mounting hole. The limiting plate is fixedly mounted on the mounting frame, and the ends of the first embossing roller and the second embossing roller are located in the first mounting hole and the second mounting hole, respectively.

[0010] Furthermore, the limiting component also includes a spring disposed between the pressure bar and the locking block, and a locking block insert is provided at the end of the locking block. The spring is sleeved on the locking block insert so that when both ends of the pressure bar are fixedly connected to the limiting plate, the spring provides elastic compensation to the locking block.

[0011] Furthermore, the embossing core for packaging cushioning paper products also includes a guide assembly, which includes a feeding guide assembly and a discharging guide assembly with the same structure. The feeding guide assembly is positioned above the first embossing roller and the second embossing roller, and the discharging guide assembly is positioned below the first embossing roller and the second embossing roller.

[0012] Furthermore, the feeding guide assembly includes two symmetrically arranged guide plates to form a feeding gap between the two guide plates; the upper part of the guide plate is provided with a bent top edge that bends outward so that the two guide plates form a flared opening above the feeding gap, which facilitates the entry of packaging cushioning paper into the feeding gap.

[0013] Furthermore, the discharge guide assembly includes two symmetrically arranged guide plates to form a discharge gap between the two guide plates; the upper part of the guide plate is provided with a bent top edge that bends outward so that the two guide plates form a flared opening above the discharge gap, which facilitates the entry of the processed packaging cushioning paper into the discharge gap.

[0014] Furthermore, the embossing block is rectangular in shape, and the top of the embossing block is chamfered to facilitate the embossing block to press the packaging cushioning paper.

[0015] Furthermore, the guide plate has bent sides at both ends to facilitate fixing the two ends of the guide plate to the mounting bracket.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting an annular die on the first and second embossing rollers, the packaging cushioning paper can enter between the first and second embossing rollers like paper entering a shredder. The rotation of the annular die forms a stamping on the surface of the packaging cushioning paper, creating concave and convex areas, which can be conveniently used for cushioning packaging inside express delivery boxes. The shredder-style design allows the packaging cushioning paper to be used directly in the packing area, and the size of the stamped packaging cushioning paper can be flexibly adjusted according to the size of the packing box. It is convenient, improves packaging efficiency, and reduces costs; the flared top edge of the guide plate forms a trumpet-shaped opening, which facilitates the feeding and unloading of packaging cushioning paper; the clamping block is fixed to the limiting plate by the cooperation of pressure strip and spring, which forms an elastic buffer for the clamping block, so that when the packaging cushioning paper enters between the first embossing roller and the second embossing roller for punching, the second embossing roller placed in the second mounting hole can move elastically, so that the punching can proceed smoothly while reducing rigid damage to the embossing block, the first embossing roller and the second embossing roller; the sliding cooperation of the limiting groove and the limiting block facilitates the quick assembly and limiting of the ring die.

Both ends of the first embossing roller 11 and the second embossing roller 12 are respectively disposed within a limiting assembly 40. The limiting assembly 40 includes a limiting plate 41, a locking block 42, and a pressure strip 43. One end of the limiting plate 41 has a first mounting hole 411, and the other end of the limiting plate 41 has a rectangular frame 412. The locking block 42 is slidably engaged with the rectangular frame 412. A half-section of the limiting plate is disposed on the rectangular frame 412. The circular hole 413 and the locking block 42 are provided with a locking block semicircular hole 421 that matches the semicircular hole 413 of the limiting plate. The two ends of the pressure strip 43 are respectively provided with screw holes 432 so that when the pressure strip 43 is fixedly connected to the limiting plate 41 by screws, the locking block 42 is fixed in the rectangular frame 412. At this time, the semicircular hole 413 of the limiting plate and the semicircular hole 421 of the locking block form a second mounting hole. The limiting plate 41 is fixedly mounted on the mounting frame 20 by screws. The ends of the first embossing roller 11 and the second embossing roller 12 are rotatably mounted in the first mounting hole 411 and the second mounting hole through the bearing 13.

[0020] The limiting assembly 40 also includes a spring 431 disposed between the pressure strip 43 and the locking block 42. Each locking block 42 has two locking block inserts 422 at its end. The spring 431 is sleeved on the locking block inserts 422 so that when the two ends of the pressure strip 43 are fixedly connected to the limiting plate 41, the spring 431 provides elastic compensation to the locking block 42. This allows the second embossing roller 12, which is placed in the second mounting hole, to move elastically when the packaging cushioning paper is pressed between the first embossing roller 11 and the second embossing roller 12.
