Description

Technical Field

[0001] This utility model relates to the field of multi-head scale technology, and in particular to a multi-head scale for dispensing. Background Technology

[0002] Multi-head scales are intelligent packaging equipment typically used for the rapid weighing and dispensing of goods such as food, chemicals, and pharmaceuticals. A key feature of multi-head scales is their ability to perform multiple weighing operations simultaneously, improving production efficiency and accuracy. However, for small, fragile materials such as milk powder (formed from milk powder) and candy, the upper and lower buffer hoppers, weighing hoppers, and the lower feeding plate are all made of hard stainless steel. When these fragile materials fall into the buffer and weighing hoppers, they collide with the inner walls and feeding plate, causing localized damage and producing powder. This powder not only contaminates the packaging machine's environment but can also enter the packaging bags, affecting the actual quality of the packaged goods.

[0003] For example, patent document CN201921592593.X discloses a high-efficiency multi-head dispensing scale, which includes a support frame fixedly mounted on the ground. A multi-head scale body is fixedly mounted on top of the support frame. The upper part of the multi-head scale body has a feed inlet, and the lower part of the multi-head scale body has multiple discharge troughs evenly arranged circumferentially corresponding to each hopper. A buffer hopper is located below the multi-head scale body. The top of the buffer hopper is connected to the bottom of the multi-head scale body and is provided with an upper cover. The upper cover has a material passage groove with the same outline as the discharge troughs. The outer side of the lower half of the buffer hopper is connected to a first motor located on the outer side of the support frame for driving the buffer hopper to rotate. In the above scheme, the weighed material enters the receiving hopper from the buffer hopper. The roller below the receiving hopper is rotating under the action of the second motor. The material in the receiving hopper will enter the receiving trough located at the feed inlet and follow the rotation of the roller until it moves to the discharge outlet and falls onto the conveyor belt to be transported to the next process. This avoids the material from scattering or mixing, and ensures accurate and uniform weight distribution.

[0004] In the above scheme, the rotation of the drum is driven by a second motor. However, when the second motor malfunctions, the material in the receiving hopper cannot accurately enter the receiving trough, requiring frequent maintenance and adjustment, which increases the workload. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a multi-head weigher for dispensing materials, which can reduce the probability of breakage of fragile materials, while also reducing the overall maintenance frequency and effectively decreasing the overall workload.

[0006] According to a first aspect of the present invention, a multi-head scale includes a multi-head scale body and a feeding mechanism connected to the bottom discharge port of the multi-head scale body. The feeding mechanism includes a balance seat, a buffer structure connected to the front and rear sides of the balance seat, and a counterweight. The weight of the buffer structure is the same as the weight of the counterweight. A hanging rod is rotatably connected to both sides of the balance seat, and the top of the hanging rod is connected to the bottom discharge port of the multi-head scale body. The buffer structure includes a base plate connected to the balance seat, a baffle connected to the base plate, a shock-absorbing component connected to the base plate and located in the baffle, and a guide plate connected to the side of the base plate away from the balance seat.

[0007] The multi-head weigher for dispensing according to the present utility model has at least the following beneficial effects: by setting up a balance seat, counterweight and buffer structure, when the material falls on the buffer structure under the action of gravity, the balance between the counterweight and the buffer structure is broken, the buffer structure will deflect, and the material can slide down along the guide plate into the packaging bag. The existence of the buffer structure reduces the speed and impact force when the material comes into contact with the feeding mechanism, reduces the occurrence of powder production, and reduces the number of maintenance times and workload.

[0008] According to some embodiments of this utility model, the enclosure is a corrugated pipe structure, and the top of the enclosure is connected to the outer periphery of the bottom discharge port of the multi-head scale body.

[0009] According to some embodiments of this utility model, the balance seat is connected to two rotating shafts on both sides, and the rod is provided with corresponding rotating holes. The rotating shafts cooperate with the rotating holes and are movably connected by bearings.

[0010] According to some embodiments of the present invention, the shock absorption assembly includes a first buffer pad and a second buffer pad connected sequentially from bottom to top. The first buffer pad and the second buffer pad have the same thickness, and an elastic element connects the first buffer pad and the second buffer pad.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] refer to Figure 1 As shown, the multi-head scale according to an embodiment of the present invention includes a multi-head scale body (not shown in the figure) and a feeding mechanism connected to the bottom discharge port (not shown in the figure) of the multi-head scale body. The feeding mechanism includes a balance seat 100 and a buffer structure and a counterweight 300 connected to the front and rear sides of the balance seat 100. The weight of the buffer structure is the same as the weight of the counterweight 300. The two sides of the balance seat 100 are rotatably connected to the hanging rods 220, and the top of the hanging rods 220 is connected to the bottom discharge port of the multi-head scale body. The buffer structure includes a base plate 210 connected to the balance seat 100, a baffle 230 connected to the base plate 210, a shock-absorbing component connected to the base plate 210 and located in the baffle 230, and a guide plate 250 connected to the side of the base plate 210 away from the balance seat 100.

[0027] refer to Figure 1 as well as Figure 2 As shown in the figure, the arrow indicates the direction of material falling. In actual use, through the setting of the balance seat 100, counterweight 300 and buffer structure, when the material falls on the buffer structure under the action of gravity, the balance between the counterweight 300 and the buffer structure is broken, the buffer structure will deflect, and the material can slide down along the guide plate 250 into the packaging bag. The existence of the buffer structure reduces the speed and impact force when the material comes into contact with the feeding mechanism, reduces the occurrence of powder production, and reduces the number of maintenance times and workload.

[0028] In some specific embodiments of this utility model, it may also have the following additional technical features: the enclosure 230 is a corrugated pipe structure, and the top of the enclosure 230 is connected to the outer periphery of the bottom discharge port of the multi-head scale body.

[0029] By using the corrugated pipe structure of the enclosure 230, it can not only surround the material, but also have a certain deformation when the base plate 210 rotates, so that it can expand and contract with the base plate 210.

[0030] In some specific embodiments of this utility model, it may also have the following additional technical features: the balance seat 100 is connected to the two sides of the rotating shaft 110, and the hanging rod 220 is provided with a corresponding rotating hole 221. The rotating shaft 110 and the rotating hole 221 are engaged and movably connected through the bearing 120.

[0031] The above design ensures that when the material falls onto the buffer structure under gravity, the balance between the counterweight 300 and the buffer structure is broken. Since the balance seat 100 and the hanging rod 220 are rotatably connected, the buffer structure will deflect, allowing the material to fall into the packaging bag through the guide plate 250.

[0032] It should be noted that bearing 120 is a commonly used technical solution in the existing technology. The corresponding model can be obtained by consulting reference books and purchasing it on the market according to the actual needs and parameters. Its specific structure and principle will not be described in detail here.

[0033] In some specific embodiments of this utility model, it may also have the following additional technical features: the shock absorption component includes a first buffer pad 241 and a second buffer pad 242 connected sequentially from bottom to top. The first buffer pad 241 and the second buffer pad 242 have the same thickness, and an elastic element is connected between the first buffer pad 241 and the second buffer pad 242.

[0034] In some specific embodiments of this utility model, it may also have the following additional technical features: the first buffer pad 241 and the second buffer pad 242 are both made of rubber pads.

[0035] Preferably, the surface of the second buffer pad 242 is covered with a waterproof and oil-resistant film (not shown in the figure). Since the presence of moisture and oil can increase powder adhesion, adding a waterproof and oil-resistant film can reduce powder adhesion. The waterproof and oil-resistant film can use commonly used technical solutions in the prior art, which will not be described in detail here.

[0036] refer to Figure 1 As shown, in some specific embodiments of this utility model, it may also have the following additional technical features: there are multiple elastic elements, and all of the multiple elastic elements are springs 243.

[0037] refer to Figure 2 As shown, in some specific embodiments of this utility model, it may also have the following additional technical features: the elastic element is an airbag 244.

[0038] In some specific embodiments of this utility model, it may also have the following additional technical features: a through hole (not shown in the figure) is provided on the side wall of the enclosure 230, and the inflation port 245 of the airbag 244 is connected to an external air supply device (not shown in the figure) through the through hole via an air pipe.

[0039] It should be noted that the external air supply equipment can be equipment such as air pumps and air tanks commonly used in the prior art, and it is not the focus of protection of this application, so it will not be described in detail here.

[0040] In some specific embodiments of this utility model, it may also have the following additional technical features: a plurality of dampers 246 are uniformly connected on the outer periphery of the elastic element.

[0041] Through the above design, when the material impacts the second buffer pad 242, on the one hand, the airbag 244, the first buffer pad 241, and the second buffer pad 242 effectively provide elastic support, and on the other hand, the damper 246 effectively ensures that the second buffer pad 242 can move evenly when impacted, thereby dispersing the force.

[0042] In some specific embodiments of this utility model, it may also have the following additional technical features: the counterweight 300 is a magnet. With this design, an iron block or magnet can be attracted to the counterweight 300 according to actual needs, thereby adjusting the weight of the counterweight 300, which facilitates different adjustments based on the actual material product.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
