Description

Technical Field

[0001] This utility model belongs to the field of chemical fiber raw material packaging, and specifically relates to a weighing auxiliary device for chemical fiber raw material space bags. Background Technology

[0002] The raw materials used in the manufacture of polyester staple fiber are basically recycled polyester bottle flakes, recycled polyester waste yarn and waste materials, polyester bubble material, etc.

[0003] In the production of polyester staple fiber, the manufacturing workshop needs to weigh out a certain weight of the raw materials using packaging bags. Currently, with the increasing use of large bags (space bags) for raw material packaging, each bag has a different weight, requiring weighing of each bag to ensure consistency. Observations of the large bag weighing operation reveal that when using a forklift, the connecting straps at the top of the bag are prone to breakage, posing a significant safety hazard to personnel below. Using an overhead crane for weighing is inefficient and cannot complete the task. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for weighing chemical fiber raw material space bags, which can prevent the space bags from hitting the operators, improve operational safety, and ensure the efficiency of raw material weighing.

[0005] The purpose of this utility model is achieved as follows: A weighing auxiliary device for chemical fiber raw material space bags includes a movable frame. The movable frame includes a horizontal base plate, with side baffles vertically arranged on both the front and rear sides of the base plate. A weighbridge is installed on the base plate, with two side baffles respectively corresponding to the front and rear sides of the weighbridge. Each side baffle has two vertically arranged symmetrically distributed vertical mounting rods on its upper side. A reinforcing rod is horizontally arranged between the middle of the two corresponding mounting rods. The upper end of each mounting rod is connected to a downwardly extending connecting chain. The lower end of each connecting chain is fixed to the outer edge of the support frame. The support frame is correspondingly arranged above the weighbridge.

[0006] This invention is used for weighing chemical fiber raw materials. A forklift holds the upper strap of the bulk bag (large bag), then the forklift moves the bulk bag (large bag) to a support frame. Next, the bulk bag (small bag) is placed on the weighbridge. Personnel climb onto the bottom plate and open the unloading port of the bulk bag (large bag) or cut open the bottom of the large bag with a knife to allow material to fall into the bulk bag (small bag). When the weighbridge reading for the bulk bag (small bag) reaches the corresponding weight, the small bag is closed, completing its quantitative weighing. Then, the quantitative weighing of the next small bag can be performed. Compared with existing technologies, the advantages of this invention are: it prevents the bulk bag from hitting the operator, improving operational safety, and ensuring the efficiency of raw material weighing.

[0007] As a further improvement of this utility model, the base plate is rectangular, the upper surface of the side baffle is higher than the upper surface of the base plate, and a caster wheel is provided at each of the four corners of the lower side of the base plate. The caster wheel is a universal caster wheel with brakes. The caster wheel can be used to move the mobile frame to other workshops and factories, making weighing more convenient.

[0008] As a further improvement of this utility model, the weighbridge is rectangular, and a positioning groove is provided on the base plate corresponding to the weighbridge, and the weighbridge is installed in the positioning groove. This facilitates the positioning of the weighbridge and prevents misalignment.

[0009] As a further improvement of this utility model, a horizontal reinforcing rod is provided between the upper ends of the two corresponding mounting rods. The reinforcing rod improves the front-to-back connection strength of the mounting rods, and the reinforcing rod improves the left-to-right connection strength of the mounting rods.

[0010] As a further improvement of this utility model, the connecting chain is inclined and is an iron chain.

[0011] As a further improvement of this utility model, the support frame is an iron ring, and the lower end of the connecting chain is fixed to the edge of the iron ring. The position of the support frame is fixed by four connecting chains.

[0012] As a further improvement of this utility model, the support frame includes an inner ring and an outer ring arranged coaxially, with the inner and outer rings at the same height. A plurality of first connecting rods evenly distributed circumferentially are provided between the inner and outer rings, and the first connecting rods are radially arranged. An upper retaining ring is provided corresponding to the outer ring, with the height of the upper retaining ring being higher than that of the outer ring. A plurality of second connecting rods evenly distributed circumferentially are provided between the upper retaining ring and the outer ring. The lower end of the connecting chain is fixed to the upper retaining ring. The support frame supports the large bag (space bag), with the inner and outer rings supporting the large bag from the bottom, and the upper retaining ring blocking the outer perimeter of the large bag from the outside to prevent misalignment. Material discharged from the discharge port of the large bag passes downwards through the inner ring and enters the small bag. Attached Figure Description
