Description

Technical Field

[0001] The utility model relates to the technical field of weighing buckets, in particular to a conical weighing bucket. Background Art

[0002] A weighing hopper is a device used to accurately measure the quantity or weight of materials during the packaging process. When materials enter the hopper, a weighing sensor senses the combined weight of the hopper and the materials. Initially, a tare operation records the weight of the empty hopper. As materials are added, the sensor converts the weight change into an electrical signal, which is transmitted to the control system. When the preset weight is reached, the control system signals the closing of the feed port and the opening of the discharge port for packaging.

[0003] However, when the existing weighing hopper is in use, some materials are easily accumulated on the inner wall of the weighing hopper, resulting in unsmooth material discharge, which affects work efficiency. At the same time, when materials enter and exit the weighing hopper for a long time, the materials and the inner wall are constantly rubbed, especially when the granular or powdered materials contain particles with higher hardness, the inner wall surface will gradually be worn. The worn weighing hopper needs to be replaced, which increases the production cost of the enterprise. Utility Model Content

[0004] In order to solve the problems existing in the background technology, the utility model provides a conical weighing bucket, which solves the problem that when the existing weighing bucket is in use, some materials are easily accumulated on the inner wall of the weighing bucket, resulting in insufficient material discharge, thereby affecting work efficiency. At the same time, when materials enter and exit the weighing bucket for a long time, the materials and the inner wall are constantly rubbed, especially when the granular or powdered materials contain particles with higher hardness, the inner wall surface will gradually be worn. The worn weighing bucket needs to be replaced, thereby increasing the production cost of the enterprise.

[0005] In response to the problems in the existing technology, the utility model provides a conical weighing hopper including a hopper, wherein a feed port and a discharge port are respectively provided at both ends of the hopper, a protective mechanism is provided inside the hopper, and a plurality of telescopic mechanisms are provided on the outer wall of the central circumference of the hopper.

[0006] Specifically, the upper and lower surfaces of the hopper are each provided with a plurality of evenly distributed threaded holes along the circumferential direction.

[0007] Specifically, a plurality of through holes are uniformly provided on the outer circumferential wall in the middle portion of the hopper along the circumferential direction.

[0008] Specifically, the protective mechanism includes an inner lining that is in contact with the inner wall of the hopper. The upper surface of the inner lining is fixedly connected to a first mounting plate that is in contact with the upper surface of the hopper. The lower surface of the inner lining is fixedly connected to a second mounting plate that is in contact with the lower surface of the hopper. The first mounting plate and the second mounting plate are both provided with mounting holes corresponding to the position and number of the threaded holes.

[0009] Specifically, the mounting hole and the threaded hole are fixedly connected by bolts.

[0010] Specifically, the telescopic mechanism includes a support plate fixedly mounted on the outside of the through hole on the outer circumferential wall in the middle of the hopper, a cylinder is fixedly mounted on the side wall of the support plate, and the output end of the cylinder passes through the side wall of the support plate and is fixedly mounted with a top plate.

[0011] Specifically, the lining is made of flexible material.

[0012] Specifically, the cylinder is tilted and adapted to the curvature of the outer wall of the hopper.

[0013] Beneficial effects of the utility model:

[0014] The conical weighing hopper drives the top plate to squeeze the lining through the output end of the cylinder, causing the lining to deform, thereby discharging the material accumulated on the lining, greatly improving work efficiency. At the same time, after the hopper has been used for a long time, only the worn lining needs to be replaced, which greatly reduces the company's production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the technical methods, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4The conical weighing hopper shown includes a hopper 1, with a feed port 11 and a discharge port 12 respectively provided at both ends of the hopper 1. A protective mechanism 5 is provided inside the hopper 1, and multiple groups of telescopic mechanisms 7 are provided on the outer circumference of the middle part of the hopper 1.

[0023] Furthermore, a plurality of evenly distributed threaded holes 13 are provided on the upper and lower surfaces of the hopper 1 along the circumferential direction.

[0024] Furthermore, a plurality of through holes 14 are uniformly formed on the outer circumferential wall of the middle portion of the hopper 1 along the circumferential direction.

[0025] Furthermore, the protective mechanism 5 includes a lining 51 that is fitted around the inner wall of the hopper 1. The upper surface of the lining 51 is fixedly connected to a first mounting plate 52 that is fitted to the upper surface of the hopper 1, and the lower surface of the lining 51 is fixedly connected to a second mounting plate 53 that is fitted to the lower surface of the hopper 1. The first mounting plate 52 and the second mounting plate 53 are both provided with mounting holes 54 corresponding to the position and number of the threaded holes 13. The mounting holes 54 and the threaded holes 13 are fixedly connected by bolts 6. When the hopper 1 is used for a long time, the inner lining 51 is worn out. At this time, it is only necessary to remove the bolts 6 on the first mounting plate 52 and the second mounting plate 53 to separate the lining 51 from the hopper 1, and then install the new lining 51 inside the hopper 1 and re-tighten the bolts 6, which greatly reduces the production cost of the enterprise.

[0026] Furthermore, the telescopic mechanism 7 includes a support plate 71 fixedly mounted on the outside of the through hole 14 on the outer circumferential wall in the middle of the hopper 1, and a cylinder 72 is fixedly mounted on the side wall of the support plate 71. The output end of the cylinder 72 passes through the side wall of the support plate 71 and is fixedly mounted with a top plate 73. When the material accumulates on the liner 51, the cylinder 72 is turned on, and the output end of the cylinder 72 drives the top plate 73 to reciprocate and squeeze the liner 51, causing the liner 51 to deform, thereby discharging the material accumulated on the liner 51. When the cylinder 72 reciprocates, it will also generate a certain vibration, further discharging the material accumulated on the liner 51, thereby greatly improving work efficiency.

[0027] Furthermore, the lining 51 is made of a flexible material.

[0028] Furthermore, the cylinder 72 is tilted and adapted to the curvature of the outer wall of the hopper 1 .

[0029] Working principle: When in use, the material enters the hopper 1 through the feed port 11, most of the material is discharged through the discharge port 12, and a small amount of material adheres to the lining 51. At this time, the cylinder 72 can be used, and the output end of the cylinder 72 drives the top plate 73 to reciprocate and squeeze the lining 51. The lining 51 is deformed, thereby discharging the material accumulated on the lining 51. While the cylinder 72 reciprocates, it also generates a certain vibration, which further discharges the material accumulated on the lining 51. After the hopper 1 has been used for a long time, the inner lining 51 is worn. At this time, you only need to remove the bolts 6 on the first mounting plate 52 and the second mounting plate 53 to separate the lining 51 from the hopper 1, and then install the new lining 51 to the inside of the hopper 1 and re-tighten the bolts 6.
