Description

Technical Field

[0001] The utility model relates to a side dumping type counterweight scale. Background Art

[0002] At present, there are many practical demands in the packaging industry that require materials to be paired and mixed before packaging and then reach the target weight. With the development of high technology today, this demand can be solved by automated equipment. There are many material weighing scales on the market, which generally have the characteristics of fast speed, high precision, and reduced labor.

[0003] The most commonly used counterweight scale for bulk materials is the belt counterweight scale. It performs high-speed calculations and processing according to weight targets. The control system selects six belt-conveyed weighing units on each side of the belt counterweight scale that meet the quantitative targets, with a long conveyor belt in the middle. When counterweighting, the pre-packaged quantitative weight target is first set, and then the material is manually added to the empty weighing unit of the counterweight scale. After the material is added, each pallet is automatically weighed and the weight is recorded. The automatic counterweight control system then calculates and confirms the optimal value of the preset weight target and commands the successfully paired weighing unit to convey the material to the middle conveyor belt. The material is then quickly transported to the packaging station by the conveyor line, thus completing the entire automatic counterweight combination process. However, belt slippage can lead to inaccurate speed matching.

[0004] In the belt counterweight scale structure, the weighing units are set on both sides of the counterweight scale. Workers and materials to be weighed need to be arranged on both sides at the same time, which requires a large space and requires manual placement of materials around the counterweight scale multiple times in advance, increasing working time and work intensity. During the matching process of the belt counterweight scale, materials on the weighing unit that are not successfully matched will occupy the work station until they are successfully matched and will be discharged from the weighing unit, resulting in a waste of time on the weighing unit and low work efficiency.

[0005] The existing tipping combination weigher has a V-shaped tipping bucket and a plurality of anti-sticking grooves on the bucket wall. When pouring materials into the lower combination bucket, the tipping bucket needs to rotate in the opposite direction to return to its original position after rotating to pour materials, which wastes time. It also has problems such as unclean dumping and long waiting time at the work station. Utility Model Content

[0006] The technical problem to be solved by the present invention is generally to provide a side-dumping counterweight scale, which can be used to combine multiple block materials into a set target weight, replacing manual weighing and then combining the counterweight calculation.

[0007] In order to solve the above problems, the technical solution adopted by the present invention is:

[0008] In order to realize continuous action, a side-discharging counterweight scale includes a main frame; a plurality of weighing components are arranged on the main frame;

[0009] The weighing assembly includes an upper weighing bucket that is rotatably arranged;

[0010] The upper weighing bucket rotates through the blanking station and the falling station.

[0011] As a further improvement of the above technical solution:

[0012] In order to realize the falling of materials, the upper weighing bucket is used to receive the materials at the material dropping station;

[0013] In order to realize material output, at the falling station, the upper weighing bucket dumps the material received at the dropping station;

[0014] In order to achieve continuous work, the drop station includes drop station A and / or drop station B;

[0015] When the material received by the blanking station reaches the set weight, the upper weighing bucket rotates, causing the material to fall from the blanking station to the falling station and separate from the upper weighing bucket.

[0016] In order to achieve better material loading, the upper weighing bucket has a middle recess for loading materials;

[0017] In order to improve efficiency, the upper weighing bucket is a Y-shaped structure or an H-shaped structure;

[0018] The middle concave part of the Y-shape corresponds to the falling station and the blanking station.

[0019] In order to reduce friction, the upper weighing bucket includes several partition members;

[0020] Spaces are provided between adjacent partition members.

[0021] The partition members are connected in series through connecting rods;

[0022] In order to form a gap, a gap portion is provided on the connecting rod; the gap portion is located at the gap position;

[0023] The spacer portion is a spacer sleeve or a spacer step.

[0024] In order to achieve continuous rotation, the upper weighing bucket transmission is connected with a side dump drive assembly;

[0025] In order to achieve weighing, the side dump drive assembly includes a weighing mounting seat arranged on the main frame; a weighing sensor is arranged between the main frame and the weighing mounting seat;

[0026] A driving motor is provided on the main frame, and the driving motor is connected to a connecting shaft through a coupling;

[0027] The connecting shaft member is connected to the partition member;

[0028] Outer baffle members are provided at both ends of the partition member;

[0029] The outer baffle member is connected to the connecting shaft member.

[0030] In order to temporarily store quantitative materials, a buffer component is provided below the weighing component;

[0031] The buffer assembly includes a lower buffer bucket that is opened and closed;

[0032] The lower buffer hopper is located below the upper weighing hopper.

[0033] In order to realize the flipping of the lower buffer bucket, the lower buffer bucket is connected to an opening and closing drive assembly;

[0034] The opening and closing drive assembly includes a fixed cylinder mounting seat and a swing shaft mounting seat; a cylinder assembly is arranged on the cylinder mounting seat;

[0035] A swing connecting shaft rotates on the swing shaft fixing seat; the swing connecting shaft is connected to the lower buffer bucket;

[0036] A swing shaft clamping block is hinged between the swing connecting shaft and the cylinder assembly.

[0037] In order to reduce friction and achieve better material falling, the lower buffer bucket is M-shaped, with the opening facing the end.

[0038] The utility model has the advantages of reasonable design, low cost, durability, safety and reliability, simple operation, time and labor saving, money saving, compact structure and easy use.

[0039] Compared to belt counterweight scales, this utility model features a completely new design concept, requiring no deflection correction and eliminating the risk of slippage. Compared to tilting combination weighers, this side-discharge counterweight scale also has a completely different structure. Its weighing bucket is Y-shaped, while the tilting bucket of a tilting combination weigher is V-shaped. Its weighing bucket operates in a single motion, while the tilting bucket of a tilting combination weigher operates in a reciprocating motion. Its weighing bucket is a stacked multi-layer plate structure, while the tilting bucket has several grooves on its walls.

[0040] The beneficial effects of the present invention are as follows: the side-dumping counterweight scale adopts an upper weighing bucket fixed on the upper part of the weighing sensor to weigh the material. After the material is weighed, the weighing bucket tilts sideways 120° to drop the material into the buffer bucket. Since the weighing bucket is a Y-shaped three-side hopper design, each time the weighing bucket tilts sideways 120°, one side of the hopper will be emptied and a new hopper will be exposed at the same time. This dumping method can reduce the shaking of the weighing bucket, which is beneficial to the stability of the weighing sensor, thereby improving the weighing accuracy of the weighing sensor, saving the weighing response time of the weighing sensor, and improving the weighing efficiency. Through the design of the above structure, each weighing bucket corresponds to two buffer buckets on the left and right, providing two materials that can participate in counterweighting, greatly improving the counterweighting probability and shortening the counterweighting time.

[0041] Compared with the belt-type counterweight scale, each weighing unit can only provide one material weight for counterweighting, and the unsuccessful matching material occupies the weighing unit for a long time, which limits the counterweighting probability. The side-dumping counterweight scale avoids the shortcomings of the belt-type counterweight scale and significantly improves work efficiency.

[0042] Compared with the belt counterweight scale, the side-dumping counterweight scale is a one-sided loading system. Workers can load materials into the weighing bucket while standing on one side of the equipment, which reduces the labor intensity of workers and does not require a large space, which is conducive to the neat placement of materials in the workshop.

[0049] like Figure 1-5 As shown, the side-discharging counterweight scale of this embodiment includes a main frame 1, which can be split or integrated; a plurality of weighing components 2 are provided on the main frame 1 to achieve weight weighing;

[0050] The weighing assembly 2 includes an upper weighing bucket 6 that is rotatably arranged to achieve unidirectional rotation and falling;

[0051] The upper weighing bucket 6 rotates through the blanking station 22 and the falling station, thereby achieving quantitative falling of materials.

[0052] At the blanking station 22, the upper weighing bucket 6 is used to receive the material until the weight meets the set requirements;

[0053] At the falling station, the upper weighing bucket 6 dumps the material received at the blanking station 22;

[0054] The dropping station includes a dropping station A23 and / or a dropping station B24; preferably, the dropping station is divided into three equal parts to achieve continuous output.

[0055] When the material received by the blanking station 22 reaches a set weight, the upper weighing bucket 6 rotates, causing the material to fall from the blanking station 22 to the falling station and separate from the upper weighing bucket 6.

[0056] The upper weighing hopper 6 has a middle recess 28 for carrying materials, thereby achieving temporary storage, and its size and depth can be adjusted according to the material conditions;

[0057] The upper weighing bucket 6 is a Y-shaped structure or an H-shaped structure, and can also be other similar structures to achieve multiple continuous actions.

[0058] The middle concave portion 28 of the Y-shape corresponds to the dropping station and the blanking station 22 , and the dropping station and the blanking station 22 are located in the lower concave portion of the Y-shape, thereby realizing temporary storage of materials.

[0059] The upper weighing bucket 6 includes a plurality of partition members 9 to realize the axial side blocking of the material;

[0060] Spaces are provided between adjacent partition members 9 to reduce friction.

[0061] The partition members 9 are connected in series as a whole through the connecting rods 7 and connected by bolts;

[0062] The connecting rod 7 is eccentric to the rotation axis of the partition member 9, which can improve the strength and prevent the material from being affected in the root recess;

[0063] A spacer 8 is provided on the connecting rod 7; the spacer 8 is located at the intermediate position;

[0064] The spacer 8 is a spacer sleeve or a spacer step.

[0065] The upper weighing bucket 6 is connected to the side dumping drive assembly 4; it can realize other rotating parts, such as gears, motors or other structures.

[0066] The side dump drive assembly 4 includes a weighing mounting base 13 provided on the main frame 1; a weighing sensor 10 is provided between the main frame 1 and the weighing mounting base 13 to achieve weight monitoring;

[0067] As a specific explanation, a driving motor 11 is provided on the main frame 1, and the driving motor 11 is connected to a connecting shaft 14 via a coupling 12;

[0068] The connecting shaft member 14 is connected to the partition member 9 to achieve the connection.

[0069] Outer baffles 15 are provided at both ends of the partition 9 to achieve side blocking of the material.

[0070] The outer baffle member 15 is connected to the connecting shaft member 14 .

[0071] A buffer component 3 is provided below the weighing component 2 to achieve temporary storage of materials and centralized dropping.

[0072] As a specific mechanism, the cache assembly 3 includes a lower cache bucket 21 that is openable and closable;

[0073] The lower buffer bucket 21 is located below the upper weighing bucket 6 .

[0074] The lower buffer bucket 21 is connected to an opening and closing drive assembly 5, which can be driven by a conventional swing mechanism, such as a connecting rod or a motor;

[0075] The opening and closing drive assembly 5 includes a fixed cylinder mounting base 16 and a swing shaft mounting base 18; a cylinder assembly 17 is provided on the cylinder mounting base 16;

[0076] A swing connecting shaft 20 rotates on the swing shaft fixing seat 18; the swing connecting shaft 20 is connected to the lower buffer bucket 21;

[0077] A swing shaft clamping block 19 is hinged between the swing connecting shaft 20 and the cylinder assembly 17 .

[0078] The lower buffer bucket 21 is M-shaped, with the opening of the M-shaped facing the end, so that the material can fall quickly under the action of the swinging centrifugal force.

[0079] As for the working principle, the main frame 1 is the main body, and the material falls into the middle recess 28 located at the blanking station 22. The weight is monitored by the weighing sensor 10. When the weight reaches the set weight, the driving motor 11 drives the coupling 12, the weighing mounting seat 13, and the connecting shaft 14 to rotate the outer baffle member 15 and the partition member 9, so that the material reaches the dropping station A23 or the dropping station B24 from the blanking station 22, and the material falls into the lower buffer bucket 21.

[0080] The cylinder assembly 17 drives the lower buffer bucket 21 to swing downward centrifugally through the swing shaft fixing seat 18, the swing shaft holding block 19, and the swing connecting shaft 20, so that the material falls and leaves.

[0081] Example 2, as a specific application, Figure 1-5The upper weighing hopper 6 is a Y-shaped 120° opening hopper on three sides, and the weighing hopper is designed with multi-layer partitions and hollow anti-sticking materials. The upper weighing hopper is provided with a side dumping drive component, which drives the weighing hopper to rotate 120° to both sides to dump materials. The upper weighing hopper is located above the lower buffer hopper, and each upper weighing hopper has a corresponding lower buffer hopper on both sides. The lower buffer hopper is provided with an opening and closing drive component, which drives the buffer hopper to open downward more than 60° for easy dumping. Figure 4 .

[0082] The side dumping drive assembly includes a weighing mount, a drive motor, a coupling, and a connecting shaft. The weighing mount has a built-in bearing. One end of the connecting shaft is connected to the coupling through the weighing mount, the coupling is connected to the drive motor, and the other end of the connecting shaft is connected to the weighing bucket. The weighing mount is fixed to the upper end of the weighing sensor.

[0083] The opening and closing drive assembly includes a swing connecting shaft, a swing connecting shaft fixing seat, a swing connecting shaft clamping block, a cylinder, and a cylinder mounting seat. One section of the swing connecting shaft is fixed on the swing connecting shaft fixing seat, the swing connecting shaft clamping block is connected to the swing connecting shaft clamping shaft, the end of the cylinder telescopic rod is connected to the swing connecting shaft bucket shaft clamping block, and the other end of the swing connecting shaft is connected to the lower cache bucket.

[0084] There are two cylinder mounting base mounting plates at the connecting end of the swing connecting shaft and the lower buffer bucket, and countersunk holes are provided on the mounting plates. The two sides of the buffer bucket are fixedly connected by threads with matching bolts passing through the countersunk holes of the mounting plates.

[0085] The buffer bucket is a flat plate with a plurality of long holes.

[0086] The main frame is C-shaped when viewed from the side. A pulley is installed at the bottom of the main frame, and there are retractable feet on the pulley. The upper part of the main frame is equipped with a drop station A and a drop station B. Drop station A is above the weighing bucket, and drop station B is located on the left side of the upper part of the main frame. Figure 1 .

[0087] The weighing hopper is designed with three Y-shaped hoppers, each of which has a 120° opening. Each time the weighing hopper tilts 120°, one hopper is emptied and a new hopper is exposed. This emptying method can reduce the shaking of the weighing hopper, which is beneficial to the stability of the weighing sensor, thereby improving the weighing accuracy of the weighing sensor and saving the weighing response time of the weighing sensor.

[0088] There are two buffer buckets on the left and right under each weighing bucket, providing two materials for balancing, which greatly improves the balancing probability and shortens the balancing time;

[0089] The side-loading counterweight scale has single-side loading, and workers can load the weighing bucket while standing on one side of the equipment, which reduces the labor intensity of workers.

[0090] Compared with the side-dumping counterweight scale, the weighing hopper of the utility model is a Y-shaped three-side hopper design, and each side hopper is 120° open. Each time the weighing hopper tilts 120°, one side hopper will be emptied and a new hopper will be exposed at the same time, without the need to return to the origin in the opposite direction. This dumping method can reduce the shaking of the weighing hopper, which is beneficial to the stability of the weighing sensor, thereby improving the weighing accuracy of the weighing sensor and saving the weighing response time of the weighing sensor; the driving structure of the flip-type combination scale is relatively complex and requires gears and other parts to drive. The side-dumping counterweight scale has a simple structure and is directly connected to the motor, which reduces costs and saves space. Figure 3 .
