Embodiment 1
[0048] Such as Figure 1-2 As shown, a checkweigher for slideway weighing, which includes third Support frame 13 and the 4th support frame 14, be provided with load cell 6 on the 3rd support frame 13, be provided with the weighing slideway 5 that tilts to place on load cell 6; Be provided with on the 4th support frame 14 Rejecting platform and rejecting grading mechanism 9; Rejecting platform is placed below the discharge port of weighing slide 5; The included angle between the design force direction and the material sliding direction of the weighing slideway 5 is B, 0°
[0049] The weighing slideway 5 is an inclined rigid slideway with a smooth groove on the contact surface with the material, and the angle between the axis of the groove surface and the horizontal plane is A (0°
Embodiment 2
[0077] The similarities between this embodiment and Embodiment 1 will not be repeated, and the difference is that the rejecting platform is a common power belt. The ordinary power belt is used instead of the power belt rejecting and grading device that needs to be synchronously controlled.
[0078] like Figure 6-7 As shown, the rejecting and grading device 7 is replaced by a horizontal rejecting power belt, and a driving motor, a belt, a roller, and a power belt with an electrical control scheme without linear speed synchronous control requirements on the market are adopted (such as those produced by Shanghai Yingsheng Machinery Co., Ltd. belt conveyor), the total price is 2200 RMB, and the upper plane of the belt is placed 20mm below the weighing slideway 5. All machinery, installation and electric connection are also substantially the same, and weighing instrument 15 and electric control device 16 are also the same, and just electric control device 16 also will control the...

Abstract
The invention relates to a checkweigher for weighing a slide way. The checkweigher comprises a third support frame and a fourth support frame, wherein a weighing sensor is arranged on the third support frame, and a weighed slide way which is obliquely placed is arranged on the weighing sensor; an eliminating platform and an eliminating and grading mechanism are arranged on the fourth support frame; the eliminating platform is arranged below a discharge outlet of the weighed slide way; and the weighed slide way is in rigid connection with the stressed end of the weighing sensor through a force guide rod, an included angle between the design stressed direction of the weighing sensor and the material sliding direction of the weighed slide way is B, and B is more than 0 degree and less than 90 degrees or B is more than 90 degrees and less than 180 degrees. The back end of the weighed slide way and the front end of the eliminating platform are opposite with a spacing interval and are not in contact, and the weighed slide way is higher than the front end of the eliminating platform, so that the checkweigher solves the problems that a rotating motion part in a weighing and metering unit of an existing separating and checking scale seriously affects weighing precision, economy, practicality and efficiency, as well as the problems that an eliminating and grading device affects the weighing precision and the manufacturing, debugging and maintenance cost.
Description
technical field [0001] The proposal relates to a checkweigher for slideway weighing, which is mainly used for automatic dynamic weight detection, removal or classification of intermittent bulk materials. Background technique [0002] Checkweigher is also known as sorting scale, sorting scale, sorting scale, sorting scale, rechecking scale, grading scale, multi-level sorting scale, weight label scale, etc., mainly used in production line or packaging line (also can It can be used as a stand-alone machine, or it can be manually loaded to the feeding device), and the product weight can be dynamically weighed, monitored, recorded, feedback controlled, and weight or price labels can be attached dynamically online, and the product can also be checked according to the preset weight range. Sorting, grading, and elimination. Intermittent bulk materials include but are not limited to hard materials, soft elastic materials, bagged materials, boxed materials, bottled materials, boxed m...
