Fixing part for bottom of paper-plastic product and preparation method of fixing part

Abstract

The invention discloses a fixing part for the bottom of a paper-plastic product and a preparation method of the fixing part. The fixing part comprises a fixing base, two lower side baffles are installed on the fixing base, a screw rod is installed on one lower side baffle, a guide rod is installed on the other lower side baffle, two upper side baffles are arranged above the two lower side baffles,the screw rod is in threaded connection with one upper side baffle, and the guide rod is in sliding connection with the other upper side baffle. According to the fixing part, through the arrangementof the screw rod and the guide rod, the distance between the upper side baffles and the lower side baffles can be adjusted, the fixing part can be installed at the corner position of the bottom of thepaper-plastic product, fixing of the corner positions of the paper-plastic product at different heights is achieved, and the paper-plastic product is effectively prevented from deforming in the usingprocess; and when the fixing part is degraded, no pollution component is generated, safety and environmental protection are achieved, meanwhile, the degradation rate is high, and the 25-day degradation rate of the fixing part for the bottom of the paper-plastic product is 99% to 99.5% through GB/T 20197-2006 measurement.

Description

technical field [0001] The invention relates to the technical field of fastener production, in particular to a fastener used for the bottom of a paper-plastic product and a preparation method thereof. Background technique [0002] Paper and plastic products are a new type of product produced by people in modern society, and they are mostly used for packaging in restaurants or street stalls. During the production process of paper-plastic products, fixing parts are usually installed at the bottom to increase the overall strength of the paper-plastic products. The fixing parts are usually made of plastic. [0003] The existing fixtures for the bottom of paper-plastic products cannot fix and support the corners of paper-plastic products. At the same time, the existing fixtures are usually not easy to degrade, and they are easy to pollute the environment when they are discarded.

Problems solved by technology

[0004] The object of the present invention is to provide a fixing part for the bottom of paper-plastic products and its preparation method, which solves the following technical problems: (1) the fixing part can meet the requirements of the upper side baffle plate and the lower side through the setting of the screw rod and the guide rod. The spacing of the baffles can be adjusted, and the fixing parts can be installed at the corners of the bottom of the paper-plastic products to meet the fixing of the corners of the paper-plastic products of different heights, and effectively prevent the deformation of the paper-plastic products during use; (2) Polylactide is used , polybutylene succinate and polyvinyl chloride are mixed as the base material, and mixed with grafted starch to prepare the main material of the fixing part of the present invention, which can effectively ensure the degradation of the fixing part while improving the mechanical effect and high temperature resistance of the fixing part Performance, adding sodium bismuthate, polyaluminum chloride and other substances can effectively improve the degradation efficiency of the product, and no polluting components will be generated during degradation, which is safe and environmentally friendly, and the degradation rate is high. According to GB / T20197-2006, this product is used for The 25-day degradation rate of the fixing part at the bottom of the paper-plastic product is 99-99.5%; (3) by placing the two upper side baffles on the feeding seat at the bottom of the feeding rack in the opening device, and simultaneously turning on the limit motor With the limit cylinder, the output shaft of the limit motor drives the pulley three to rotate, the pulley three drives the pulley four to rotate through the belt two, the pulley four drives the lead screw to rotate, the lead screw drives the two connecting blocks to move toward each other, and the two connecting blocks pass through two hinges The rod drives the two limit plates to rotate, the two limit plates touch the two upper baffles, the piston rod of the limit cylinder pushes the right-angle limit block, the right-angle limit block touches the two upper baffles, and the two upper baffles The side baffle is fixed on the loading seat, the reversing motor is turned on, the output shaft of the reversing motor drives the driving rod to rotate, the driving rod drives the two sprockets to rotate, and the two sprockets drive the two sprockets through two chains The second rotation, the two sprockets drive the connecting rod to rotate, the two connecting rods drive the two chain discs to rotate, the two chain discs drive the two transmission chains to rotate, the transmission chain drives the first connecting piece and the second connecting piece to rise, the second connecting piece The first connecting piece and the second connecting piece drive the feeding seat to rise to the top of the feeding frame. Through the above structure, the opening device can satisfy the cycle feeding of the two upper side baffles, and at the same time, it can be used for the two upper side baffles after bonding. The baffle is automatically clamped, with a high degree of automation; (4) The threaded drill bit and the hole drill bit respectively make holes on the two upper side baffles, and then the feeding seat drives the two upper side baffles down to the bottom of the feeding rack, and removes the two upper side baffles. One upper side baffle, install the guide rod and screw on the two lower side baffles, and insert the guide rod and screw into the corresponding holes of the two upper side baffles to obtain the fixing piece for the bottom of the paper-plastic product, Through the above structure, the hole opening equipment can meet the double hole opening of the two upper side baffles at the same time, automatic hole opening and high hole opening efficiency
