4results about How to "Stable feeding speed" patented technology

This invention belongs to the field of plastic processing and packaging technology, and specifically to a quantitative packaging method for plastic granules for sale. The method includes the following steps: raw material pretreatment, precision feeding, dynamic weighing, automatic bagging, vacuum heat sealing, online quality inspection, intelligent traceability code printing and labeling, automatic palletizing, and finished product warehousing. In the pretreatment stage, the invention utilizes a fully enclosed chamber with a temperature of 18-22℃ and humidity ≤40%RH, combined with a vibrating screen and an ion wind electrostatic eliminator. This achieves a plastic granule moisture content ≤0.08%, a surface dust and agglomerate removal rate ≥99.5%, and a dust concentration ≤0.5mg / m³. This eliminates the problems of electrostatic agglomeration and dust dispersion in existing technologies, ensuring smooth subsequent feeding and accurate weighing. It also significantly improves the working environment, meeting environmental protection and safety production requirements. The invention employs a dual-sensor electronic scale to achieve dual-stage control of coarse and fine feeding, improving accuracy by more than 20 times compared to existing technologies. This meets the stringent requirements for net / gross weight for sales and significantly shortens the production cycle.

The utility model provides a handle of a seeder, which comprises a handle body, the handle body is movably provided with a button, the button is provided with a support, the support is movably provided with a movable part, the movable part is fixedly provided with a connecting belt, the movable part is provided with a clamping block and a connecting arm, the connecting arm elastically abuts against the support through a first spring, and the handle body is movably provided with a knob. The knob is fixedly connected with a special-shaped wheel, the clamping block movably abuts against the special-shaped wheel, the handle body is provided with a supporting arm, and the supporting arm elastically abuts against the support through a second spring. The special-shaped wheel is spiral, the knob is rotated to drive the special-shaped wheel, so that the initial position of the clamping block is adjusted, the initial position of the movable part is controlled, the initial compression amount of the first spring is adjusted, and the support pushes the movable part to move through the first spring, so that the acting force of the button on the movable part is stable; the force acting on the blanking switch is stable, so that the blanking speed of the seeder is stable, and the seeding uniformity is improved.

The utility model relates to the technical field of friction material manufacturing, and particularly discloses a friction material manufacturing tool material pouring device which comprises a material pouring device box body and a rotating disc rotationally connected in the material pouring device box body, a plurality of groups of fixing cylinders are installed on the rotating disc, adjusting cylinders are connected to the outer walls of the fixing cylinders in a sleeved mode, and the adjusting cylinders are arranged on the rotating disc. A plurality of groups of adjusting cylinders are arranged on the fixed cylinder, a group of limiting discs are in lap joint with the bottoms of the plurality of groups of adjusting cylinders, and positioning assemblies used for adjusting the adjusting cylinders to slide on the fixed cylinder are arranged on the limiting discs, so that by arranging the rotating disc, the fixed cylinder, the positioning assemblies and the driving assemblies, the adjusting cylinders slide on the fixed cylinder, the weight of mixed raw materials fed at a time can be adjusted; the positioning assembly fixes the adjusting cylinder, the driving assembly drives the rotating disc to drive the fixing cylinder and the adjusting cylinder to rotate, through multiple times of small-amount feeding, the feeding speed can be more stable, meanwhile, the situation that due to the fact that too many packaging raw materials are fed at a time, caking and uneven mixing are caused is avoided, and the mixing efficiency is improved.

The utility model discloses a double-station feeding structure for glass production detection, and relates to the technical field of glass detection. The feeding device comprises a support, two clamping mechanisms and two feeding mechanisms are arranged on the support, each clamping mechanism comprises a connecting block arranged in the support, two first grooves are formed in the top of each connecting block, second grooves are formed in the bottoms of the two first grooves, each feeding mechanism comprises a third groove formed in the top of the support, and the second grooves are formed in the bottoms of the second grooves. And the outer wall of the connecting block is slidably connected with the third groove, a fourth groove is formed in the inner wall of the third groove, and the inner walls of the two first grooves are each slidably connected with two first sliding blocks. According to the feeding structure for the double-station glass production detection, by arranging the clamping mechanism, the problems that in the using process of an existing feeding structure for the double-station glass production detection, glass needing to be detected is inconvenient to clamp, in the feeding process, the glass is prone to deviation, and consequently the feeding process is blocked and even the glass falls off and is damaged are solved; and the production efficiency and the product yield are seriously influenced.
