Embodiment 1
[0039] Such as Figure 1-2 Shown, a kind of checkweigher of slideway weighing, it comprises the 3rd support frame 13 and the 4th support frame 14, is provided with load cell 6 on the 3rd support frame 13, is provided with load cell 6 The weighing chute 5 placed obliquely; the fourth support frame 14 is provided with a rejecting platform and a grading mechanism 9; the rejecting platform is placed below the discharge port of the weighing chute 5; The slideway 5 is rigidly connected and the load cell 6 is designed to carry a force direction perpendicular to the material sliding direction of the weighing slideway 5 . The rear end of the weighing slideway 5 is docked with the front end of the rejecting platform with a gap.
[0040] The weighing slideway 5 is a smooth groove on the contact surface with the material, the angle between the axis of the groove surface and the horizontal plane is A, and the inclined rigid slideway is 0°
Embodiment 2
[0065] Example 2: The reject platform is a normal powered belt. Use ordinary power belt instead of the power belt rejecting and classifying device 7 that needs synchronous control, see Figure 4 .
[0066] Such as Figure 4 As shown, the similarities between this embodiment and Embodiment 1 will not be described in detail. The rejecting and grading device 7 is changed to horizontally rejecting the power belt 7, and the drive motor, belt, and drum required by the common technology on the market are adopted, and there is no linear speed synchronous control requirement. The power belt of the electrical control scheme (such as the belt conveyor produced by Shanghai Yingsheng Machinery Co., Ltd.), the total price is 2200 yuan, and the upper plane of the belt is placed 20mm below the weighing slideway 5. All the mechanics, installation and electrical connections are also basically the same, as are the weighing instrument 15 and the electrical control device 16, but the electrica...

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 carrying end of the weighing sensor is in rigid connection with the weighed slide way, and the designed direction of carrying stress of the weighing sensor is vertical to the length direction of the weighed slide way. 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...
