Description

Technical Field

[0001] The utility model relates to the technical field of preform production, in particular to a slicing metering device for preform production. Background Art

[0002] The preform is formed by injecting raw materials into a mold at a specific temperature and pressure through injection molding. As an intermediate semi-finished product, it is then processed into a final product through blow molding. Polyester chips are the main raw materials for preform production. Polyester chips usually refer to polyester raw materials obtained through polymerization production, generally processed into sheet-like particles. It is a high-molecular compound with good environmental protection, lightness, and durability.

[0003] Currently, when producing preforms, it is necessary to quantitatively transport polyester chips. For example, a polyester chip metering and conveying device disclosed in the Chinese Patent Publication No. "CN216970061 U" includes a raw material box. One side of the outer side wall of the raw material box is fixedly connected with a metering box. A feeding port is opened at the center of the inner side wall of the metering box close to the raw material box, and the side of the feeding port close to the raw material box is communicated with the inside of the raw material box. A first rectangular groove is opened at the top of the feeding port, and a first baffle is slidably connected in the first rectangular groove.

[0004] The currently used metering device needs to place the chips in the raw material box during weighing. The chips enter the metering box from the raw material box. During metering, the chips need to slowly enter the metering box. Not only is the metering speed slow, but it is also easy to have the situation that too many chips are injected and there is no time to close the baffle, resulting in the weight exceeding the target measurement. After exceeding, it is not convenient to adjust the weight, affecting the metering efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems in the prior art that not only the metering speed is slow, but also it is easy to have the situation that too many chips are injected and there is no time to close the baffle, resulting in the weight exceeding the target measurement. After exceeding, it is not convenient to adjust the weight, affecting the metering efficiency, etc., and to propose a slicing metering device for preform production.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Design a slicing metering device for preform production, including a metering box. A leveling mechanism for leveling the top of the polyester chips is arranged at the top of the metering box. An adjusting plate is slidably connected inside the metering box. A discharging adjusting mechanism for adjusting the target measurement is arranged between the adjusting plate and the metering box. A weighing assembly is arranged at the top of the adjusting plate. An observation window for observing the position of the adjusting plate is embedded in the front of the metering box.

[0008] Further, the leveling mechanism includes a guiding frame fixed to the top of the metering box. Both sides of the guiding frame are provided with sliding grooves. Guide posts are fixed to the inner walls of the two sliding grooves, and a scraping plate is slidably connected between the two guide posts. A driving assembly is provided between the scraping plate and the guiding frame.

[0009] Further, the driving assembly includes a driving motor fixed to one end of the scraping plate. A rack plate is fixed to one side of the guiding frame where the driving motor is located. A driving gear is fixed to the output shaft of the driving motor, and the driving gear is meshed with the rack plate.

[0010] Further, the discharging adjustment mechanism includes mounting platforms fixed to both sides of the inner wall of the metering box. A first electric push rod and a second electric push rod are respectively fixed to the tops of the two mounting platforms. The top of the first electric push rod is hinged to an adjusting plate, and a guiding block is hinged to the top of the second electric push rod. One side of the bottom of the adjusting plate is fixed with a guide rod, and the guiding block is slidably connected with the guide rod. A material guiding assembly is provided between the first electric push rod and the second electric push rod and the metering box.

[0011] Further, the material guiding assembly includes a discharging groove opened on one side of the metering box. An inclined material guiding plate is fixed to the inner wall of the metering box, and one side of the material guiding plate extends to the outside of the metering box through the discharging groove. A lateral baffle is fixed between the material guiding plate and the outer surface of the metering box.

[0012] Further, the weighing assembly includes a plurality of weight sensors arranged on the top of the adjusting plate. A weighing plate is provided on the top of the weight sensors, and a rubber strip for sealing is fixed to the edge of the weighing plate.
