Description

Technical Field

[0001] This utility model relates to the field of packaging paper bag technology, and in particular to a packaging paper bag creasing and forming device. Background Technology

[0002] Paper bags are a type of packaging material widely used in business and daily life. Made of paper with a certain strength and toughness, they can effectively protect the contents. The surface of paper bags can be printed to convey product information, and they also serve to decorate and attract consumers. Paper materials have advantages over other packaging materials, as they are biodegradable and recyclable, which aligns with modern environmental protection concepts. Therefore, in a market environment where environmental awareness is increasingly strong, paper bags have gained more favor.

[0003] The crease treatment on the surface of paper bags facilitates folding and shaping, enhances the three-dimensionality and stability of the paper bags, and enables them to maintain a good shape after being loaded with goods. In the production process of packaging paper bags, the crease is an important marker to guide the accurate folding of the paper. The crease can make it clear where the paper should be bent, so that the paper bag can be smoothly transformed from flat paper into a packaging container with a three-dimensional structure.

[0004] Creases create regular edges on paper bags after folding, increasing their resistance to pressure. Creases also create reinforced lines on the handles and bottom edges. When subjected to heavy loads, these creases distribute the pressure, preventing the paper bag from tearing or deforming. However, current paper bag creases are made manually, which makes it difficult to maintain a stable and high speed, affecting production continuity and reducing efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a packaging paper bag creasing and forming device, which aims to improve the problem in the prior art where manual feeding cannot maintain a stable and high speed, affecting the continuity of production and thus reducing production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a packaging paper bag creasing and forming device, comprising a housing, a central column rotatably connected to the inner wall of the housing, a bonding column fixedly connected to the middle of the central column, a feeding belt rotatably connected to the outer wall of the bonding column, a creasing line fixedly connected to the outer wall of the feeding belt, a motor fixedly connected to the inner wall of the housing, a pulley set one fixedly connected to the output end of the motor and the outer wall of the central column, two pulley sets one rotatably connected via a transmission belt, mounting blocks fixedly connected to the outer wall of the housing, a rotating column rotatably connected between adjacent mounting blocks, a creasing wheel fixedly connected to the outer wall of the rotating column, a transmission wheel set two fixedly connected to the output end of the motor and the outer wall of the rotating column, two transmission wheel sets two rotatably connected via a transmission belt two, and an adjustment mechanism provided inside the mounting block for adjusting the creasing distance.

[0007] As a further description of the above technical solution:

[0008] The adjustment mechanism includes an arc-shaped groove, which is formed on the outer wall of the mounting block. A bearing is slidably connected to the inner wall of the arc-shaped groove. The inner wall of the bearing is fixedly connected to a rotating column. An adjustment column is fixedly connected to the outer wall of the bearing. An adjustment block is slidably connected to the other end of the adjustment column. An adjustment groove is formed on the outer wall of the mounting block.

[0009] As a further description of the above technical solution:

[0010] The bottom of the outer shell is fixedly connected to a support leg, and the bottom of the support leg is fixedly connected to a universal foot.

[0011] As a further description of the above technical solution:

[0012] The bottom of the universal foot is fixedly connected to an anti-slip pad, and the top of the outer shell is fixedly connected to a fixing block.

[0013] As a further description of the above technical solution:

[0014] A telescopic rod is fixedly connected to the outer wall of the fixed block, and a baffle is fixedly connected to the other end of the telescopic rod.

[0015] As a further description of the above technical solution:

[0016] A controller is fixedly connected to the outer wall of the housing, and the controller is electrically connected to the motor.

[0017] As a further description of the above technical solution:

[0018] One end of the adjustment groove is provided with a slot, and a fixing column is fixedly connected to the inner wall of the slot.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the adjusting block is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to the outer wall of the fixed column.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the motor drives the central column to rotate through the first pulley set and the first transmission belt. The central column drives the feeding belt to rotate through the bonding column. The motor drives the rotating column to rotate through the second transmission wheel set and the second transmission belt. The rotating column drives the pressing wheel to rotate. The pressing line on the feeding belt meshes with the edge of the pressing wheel, so that the pressing line can be pressed on the packaging paper. The transmission of the feeding belt realizes the automatic feeding of the packaging paper bag.

[0023] 2. In this utility model, the arc shape of the bearing is centered on the motor, so that the transmission belt is always taut when the rotating column slides in the arc groove, which will not affect the rotation of the pressure wheel. The adjusting column ensures that the rotation is not affected when the rotating column slides up and down. Moving the adjusting column will move the pressure wheel up or down, thereby changing the distance between the pressure line and the pressure wheel. The adjusting block can be fixed by locking into the adjusting groove, so as to achieve pressure lines for packaging paper bags of different thicknesses. Attached Figure Description
