Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of automatic weighing of bulletproof helmet large sheet material, belong to the production and processing technology field of equipment and tool class bulletproof product. BACKGROUND

[0002] Currently, the production of bulletproof helmet is composed of n large pieces (i.e. whole cutting piece) and m small pieces (elliptical cutting piece added to strengthen the strength of the top of the helmet) on the laying head mold; The large and small pieces are cut according to size from impregnated aramid fabric, and each large piece has six evenly distributed cutting seams, i.e. six piece petals, which are in the shape of fan blades. In the production process, several large pieces are usually laid on the laying head mold first. In order to compensate for the thickness difference accumulated at the top and the lower four corners of the head, one small piece needs to be laid on the top of the head. The large and small pieces are laid in a reciprocating manner. It should be noted that the last two layers must be large pieces to prevent the small pieces from leaving marks on the inner and outer surfaces of the helmet.

[0003] In the traditional production process of bulletproof helmet, the large pieces are manually picked up, which is time-consuming and labor-intensive, and the work efficiency is low. UTILITY MODEL CONTENTS

[0004] The utility model solves the technical problem of providing an automatic weighing and feeding device for bulletproof helmet large pieces that is easy to operate, reliable in performance, and automatically and accurately picks pieces.

[0005] The utility model adopts the following technical solutions:

[0006] The utility model comprises a large piece picking and feeding reciprocating driving assembly installed on the left bottom surface of the load-bearing main beam of a rack, a large piece picking and feeding lifting assembly installed at the bottom of the large piece picking and feeding reciprocating driving assembly, and a piece receiving and weighing assembly installed on the support frame of the rack; the large piece picking and feeding reciprocating driving assembly comprises a large piece reciprocating air cylinder and a sliding block A slidingly installed on a sliding rail A; the sliding rail A is fixedly installed on the bottom surface of the middle part of the load-bearing main beam; the large piece picking and feeding lifting assembly comprises a vertically arranged picking and feeding lifting air cylinder; the piece receiving and weighing assembly comprises a picking and feeding disc, a large piece vacuum chuck, a piece receiving disc, and an electronic scale.

[0007] The utility model is fixedly installed with a U-shaped tailstock on the left end bottom surface of the load-bearing main beam, fixedly installed with a right-angle connecting plate A on the bottom surface of the sliding block A, fixedly installed with an ear seat A on the end part of the cylinder body of the large piece reciprocating air cylinder, connected the ear seat A with the U-shaped tailstock, and fixedly connected the vertical side plate of the right-angle connecting plate A with the end of the piston rod of the large piece reciprocating air cylinder; the end of the piston rod of the picking and feeding lifting air cylinder is vertically downward, and a right-angle folding plate A and a right-angle folding plate B are fixedly installed on both sides of the end of the cylinder body of the picking and feeding lifting air cylinder; the top plates of the right-angle folding plate A and the right-angle folding plate B are respectively fixed with the bottom surface of the sliding block A.

[0008] The material-collecting disc is fixed to the piston rod end of the material-collecting lifting cylinder at the center of its top surface. Six mounting holes are spaced at intervals along the edge of the disc, and six large material sheet vacuum suction cups are installed in these holes. The suction cup openings of the large material sheet vacuum suction cups face downwards, and their air inlets are connected to an air source. A support platform is installed on the support frame, and seated linear cylinders are fixedly mounted at each of the four corners of the support platform. Linear bearings A, corresponding to the seated linear cylinders, are installed at each of the four corners of the material-receiving disc. The top of the cylinder is inserted into the linear bearing A with a gap; the electronic scale is placed in the middle of the support platform and corresponds to the bottom of the material tray. The material tray lifting cylinders are vertically fixed in the middle of the left and right edges of the support platform, and the two material tray lifting cylinders are symmetrically arranged with respect to the center of the support platform. A lifting plate is installed at the top of the piston rod of the material tray lifting cylinder, and the lifting plate lifts the material tray; the piston rods of the two material tray lifting cylinders rise and fall, and the lifting plate drives the material tray to be placed on the electronic scale or pushed upward away from the electronic scale.

[0009] The model of the large material sheet reciprocating cylinder of this utility model is SC40×1250S; the model of the material lifting cylinder is TCL20×250S.

[0010] The electronic scale described in this utility model is model number Toledo MT1022.

[0011] The large material sheet vacuum suction cup of this utility model is model number Dingling PA-40; the linear bearing A is model number LBBR8; and the material receiving tray lifting cylinder is model number MD20×30S.

[0012] The advantages of this invention are as follows: Before each vacuum material removal, the lifting cylinder of the material tray raises the material tray to avoid impact damage to the electronic scale. After vacuum removal, the lifting cylinder lowers the material tray and places the remaining large material sheet along with the material tray onto the electronic scale for weighing. Each weighing result is compared with the previous weighing value. If the difference is less than or equal to the weight of one large material sheet, it means that only one sheet has been removed. Next, the large material sheet reciprocating cylinder sends the removed large material sheet directly above the sheet-laying head mold. The material removal lifting cylinder lowers and sends the large material sheet to the next process. If the difference is greater than the weight of one large material sheet, the material removal lifting cylinder lowers and puts the removed large material sheet back, repeating the large material sheet removal process again. The large material sheet vacuum suction cup is used to pick up large material sheets because one side of the material sheet has an airtight film, preventing the second and subsequent layers (multi-layer material sheets) from being sucked up due to air leakage in the first layer, thus ensuring that only one sheet is removed each time during vacuum removal.

[0013] This utility model automatically picks up and delivers large material pieces, saving time and effort, with reliable performance and improved work efficiency. Attached Figure Description
