Description

Technical Field

[0001] The utility model relates to the field of weighing equipment, in particular to a continuous loss-in-weight scale. Background Art

[0002] Loss-in-weight weighing is an accurate measurement method for weighing loose materials. Loss-in-weight weighing controls the feeding speed of the feeding equipment based on the rate of reduction of the weight of the material in the weighing container, that is, the material delivery flow rate, in order to achieve the purpose of accurate and quantitative feeding.

[0003] However, the current weighing process of loss-in-weight scales is an intermittent weighing process, that is, during the weighing process, the feed valve needs to be closed, and then the material in the weighing bin is quickly discharged before the next step of feeding is carried out. Since the weighing work cannot be carried out continuously, this leads to low weighing efficiency.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] In view of the above-mentioned defects, the purpose of the utility model is to provide a continuous loss-in-weight scale, which can stagger the weighing time through a group-type coordinated weighing method, so as to achieve continuous unloading work at the unloading port.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a continuous loss-in-weight scale, including a plurality of weighing bins distributed in a ring and at least one group of material bins located above the weighing bins; each of the material bins has a corresponding discharge port; the material bins are driven by an intermittent rotating mechanism so that the discharge port is located on a planned circular track surrounded by the weighing bins and moves.

[0007] According to the continuous loss-in-weight scale of the utility model, the sub-bins are provided with a plurality of groups, only one of which is in working state, and the other sub-bins are in a sealed state; the discharge port is connected to the sub-bin in working state through a hose, and the hose extends into the internal space of the sub-bin.

[0008] According to the continuous loss-in-weight scale of the utility model, a cover plate is covered at the opening of the material distribution bin in a sealed state.

[0009] According to the continuous loss-in-weight scale of the utility model, the sub-bin is installed on a rotating support frame.

[0010] According to the continuous weightlessness scale of the utility model, the intermittent rotation mechanism comprises a first meshing disk arranged on the outer edge of the rotation support frame and a driving member meshed with the first meshing disk and driven by the rotator to rotate.

[0011] According to the continuous loss-in-weight scale of the utility model, the first meshing disk is a gear ring structure; the driving member is a gear meshing therewith, which is driven to rotate by a servo rotary motor.

[0012] The utility model provides a continuous loss-in-weight scale, including a plurality of weighing bins distributed in an annular manner, wherein the weighing bins are provided with four groups, and each weighing bin corresponds to a weighing mechanism. At least one group of feeding bins is provided above the weighing bins, and a feeding port is provided above the feeding bins; each of the feeding bins has a corresponding feeding port; the feeding bins are driven by an intermittent rotating mechanism so that the feeding port is located on a predetermined annular track surrounded by the weighing bins for movement. The continuous feeding process achieved in the present application is that the feeding port continuously drops the material into the feeding bin, and the feeding bin further drops the material into the weighing bin. When one group of weighing bins is filled with the predetermined amount of material, the intermittent rotating mechanism drives the feeding port of the weighing bin to move to the bin port of the next weighing bin for feeding. By distributing the weighing bins in an annular manner and cooperating with the feeding work of the feeding bins, this group-type coordinated weighing method can stagger the weighing time, so that the continuous feeding work of the feeding port can be achieved. By adopting the annular distribution mode, multiple groups of weighing bins can be coordinated to work. The utility model can stagger the weighing time by the group-type coordinated weighing mode, so that the continuous unloading work of the unloading port can be realized.

[0017] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] See also Figure 1 and Figure 2 The utility model provides a continuous loss-in-weight scale, which includes a plurality of weighing bins 1 distributed in an annular shape. As shown in the embodiment, the weighing bins 1 are provided with four groups, and each weighing bin 1 corresponds to a weighing mechanism.

[0019] At least one group of feeding bins 2 is arranged above the weighing bin 1, and a discharge port is arranged above the feeding bin 2; each of the feeding bins 2 has a corresponding discharge port 23; the feeding bins 2 are driven by an intermittent rotating mechanism so that the discharge port 23 is located in the planned circular track surrounded by the weighing bin 1 and moves. The continuous discharge process achieved in the present application is that the discharge port continuously drops the material into the feeding bin 2, and the feeding bin 2 further drops the material into the weighing bin 1. When one group of weighing bins 1 contains the predetermined amount of material, the intermittent rotating mechanism drives the discharge port 23 of the weighing bin 1 to move to the bin mouth of the next weighing bin 1 for discharge. By distributing the weighing bins 1 in a circular manner and coordinating the discharge work of the feeding bins 2, this group-type coordinated weighing method can stagger the weighing time, so that continuous discharge work of the discharge port can be achieved. By adopting the circular distribution method, multiple groups of weighing bins 1 can be coordinated to work.

[0020] Preferably, the sub-bins 2 of the utility model are provided with multiple groups, only one of which is in working state, and the rest of the sub-bins 2 are in sealed state. For example, in the embodiment, the sub-bins 2 are provided with two groups, one of which is in an open connected state, and the other is in a closed non-working state (the opening of the sub-bins 2 in the sealed state is covered with a cover plate 24, and the sealing work is performed through the cover plate); through the above-mentioned setting, one group of the sub-bins 2 is used for unloading work, and the rest of the sub-bins 2 are used as backup openings. When the working sub-bin 2 is blocked or other emergency situations occur, the unloading opening is connected with the sub-bin 2 used as a backup.

[0021] See also Figure 3 The feeding pipe 10 is connected to the sub-bin 2 in working state through the hose 11, and the hose 11 extends into the inner space of the sub-bin 2. In this embodiment, the feeding pipe 10 is located at the center of the proposed circular track. Through the above structure, the feeding work of the feeding pipe 10 will not be affected by the rotation state of the sub-bin 2, so that the material can be accurately fed into the sub-bin 2 in working state.

[0022] Specifically, the sub-bin 2 of the utility model is installed on a rotating support frame 20, and is connected to the main frame 21 through a rotating support shaft. The intermittent rotation mechanism includes a first meshing disk 21 arranged on the outer edge of the rotating support frame 20 and a driving member 22 meshed with the first meshing disk 21 and driven by the rotator to rotate. Specifically in this embodiment, the first meshing disk 21 is a gear ring structure; the driving member 22 is a gear meshed therewith, which is driven by a servo rotating motor to rotate. During the intermittent rotation process, the servo rotating motor drives the gear to rotate a predetermined number of circles, and further drives the first meshing disk 21 to rotate a predetermined angle.

[0023] Of course, the first meshing disk 21 and the driving member 22 can also be driven by other structures, such as a lever driving structure. However, the advantage of using a gear driving structure is that it will not extend into the opening of the material distribution bin 2 to interfere with material discharge.

[0024] In summary, the utility model provides a continuous loss-in-weight scale, including a plurality of weighing bins distributed in an annular manner, wherein the weighing bins are provided with four groups, and each weighing bin corresponds to a weighing mechanism. At least one group of feeding bins is provided above the weighing bins, and a discharge port is provided above the feeding bins; each of the feeding bins has a corresponding discharge port; the feeding bins are driven by an intermittent rotating mechanism so that the discharge port is located on a predetermined annular track surrounded by the weighing bins for movement. The continuous discharge process achieved in the present application is that the discharge port continuously drops the material into the feeding bin, and the feeding bin further drops the material into the weighing bin. When one group of weighing bins is filled with the predetermined amount of material, the intermittent rotating mechanism drives the discharge port of the weighing bin to move to the bin port of the next weighing bin for discharge. By distributing the weighing bins in an annular manner and cooperating with the discharge work of the feeding bins, this group-type coordinated weighing method can stagger the weighing time, so that the continuous discharge work of the discharge port can be achieved. By adopting the annular distribution mode, multiple groups of weighing bins can be coordinated to work. The utility model can stagger the weighing time by the group-type coordinated weighing mode, so that the continuous unloading work of the unloading port can be realized.

[0025] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
