Description
Technical Field
[0001] This utility model relates to the field of weight detection, specifically to a weighing and screening mechanism. Background Technology
[0002] During the production of magnetic cores, due to the uneven thickness of the strip, the weight of magnetic cores in the same batch will also be different after they are wound into magnetic cores. At this time, the weight of the magnetic cores can be divided into several grades, and they can be weighed one by one by a weighing mechanism and stored according to weight grade.
[0003] Currently, the magnetic cores are typically weighed one by one on an electronic scale by hand, and then manually sorted, resulting in low work efficiency and failing to meet production needs. Utility Model Content
[0004] The purpose of this invention is to provide a weighing and screening mechanism that is simple in structure and highly efficient in operation.
[0005] To achieve the above objectives, this utility model provides a weighing and screening mechanism, including a weighing component, a first rotary drive device, a material feeding component, and several material frames. The first rotary drive device is disposed on one side of the weighing component. The first end of the material feeding component is connected to the drive end of the first rotary drive device, and the second end of the material feeding component is disposed above the weighing component. The second end of the material feeding component has a through hole that penetrates the material feeding component in the vertical direction. Several material frames are disposed around the weighing component. The first rotary drive device can drive the material feeding component to rotate in both directions, so that the second end of the material feeding component can move toward the material frames.
[0006] As can be seen from the above scheme, by setting up a weighing component, the weight of each workpiece is weighed one by one; by setting up a material feeding component, the workpiece is fed into the appropriate material frame according to the pre-divided weight class; by setting up a perforation, the workpiece is facilitated to enter the perforation from top to bottom and fall onto the weighing component, ensuring that the workpiece falls accurately into the weighing area; this embodiment has the advantages of simple structure, convenient operation, ability to replace manual sorting and high work efficiency.
[0007] A further solution is to have multiple hole walls connected end to end to form an enclosed structure.
[0008] As can be seen from the above scheme, the above settings ensure that the workpiece can remain inside the perforation after entering the perforation, preventing it from falling out of the perforation, and making it convenient for the material feeder to move the workpiece when rotating in the forward or reverse direction.
[0009] A further solution is to have a weighing area in the weighing component, with the weighing area corresponding vertically to the perforation, and the shape of the weighing area matching the shape of the perforation.
[0010] A further option is that the weighing assembly includes a base plate, a load cell, and a support plate, with the load cell mounted on the base plate and the support plate mounted on the load cell.
[0011] A further embodiment includes a weighing assembly that also includes a pallet and a cover. The pallet is detachably mounted on the pallet plate, and the cover is fitted onto the base plate. The cover has a clearance hole in the middle, the pallet is exposed in the clearance hole, and the top surface of the pallet is flush with the surface of the cover.
[0012] As can be seen from the above scheme, the above settings can ensure that the workpiece can be accurately weighed and that the feeding component can smoothly move the workpiece; by setting a detachable tray, it is convenient to clean the tray regularly, and since the workpiece is in direct contact with the tray, it helps to ensure the cleanliness of the workpiece.
[0013] A further option is to provide a bending portion on at least two adjacent sides of the pallet, with the bending portion protruding downward from the bottom wall of the pallet and stopping against the side wall of the pallet.
[0014] As can be seen from the above scheme, the above settings facilitate the installation of the tray and ensure that the tray can be accurately embedded in the clearance hole of the cover, thus preventing the cover from being pushed up and causing its surface to become uneven.
[0015] A further embodiment is that the material frame includes a first material frame and a second material frame arranged adjacent to each other; a first slide is provided between the weighing component and the first and second material frames, and a switching component and two dropping channels are provided in the first slide. The two dropping channels are respectively connected to the first and second material frames, and the switching component can open any one dropping channel and simultaneously block the other dropping channel.
[0016] As can be seen from the above scheme, by setting two material drop channels in the first slide, it is beneficial to reduce the number of first slides and save space; by setting a switching component, it is convenient to switch back and forth between the two material drop channels, so that only one material drop channel can be activated at the same time.
[0017] A further embodiment is that the switching component includes a paddle, a rotating shaft, and a second rotary drive device. The rotating shaft is located in the middle of the width direction of the first slide, the paddle is sleeved on the rotating shaft, and two material discharge channels are respectively located on both sides of the paddle. The first end of the paddle extends toward the entrance of the first slide, and the second rotary drive device can drive the rotating shaft and the paddle to rotate, so that the first end of the paddle swings back and forth between the two sides of the entrance.
[0018] A further embodiment includes a third material frame, with a second slide between the weighing component and the third material frame. The second slide and the first slide are respectively located on adjacent sides of the weighing component, and the material feeding component can rotate back and forth between the first slide, the weighing component, and the second slide.
[0019] A further option is that the weighing and screening mechanism also includes a control module, which is connected to the weighing component, the first rotary drive device, and the second rotary drive device. Attached Figure Description

[0026] The first rotary drive device 2 is located on one side of the weighing component 1 and near the corner of the weighing component 1.
[0027] The first end of the material feeding component 3 is elongated and connected to the drive end of the first rotary drive device 2. The second end of the material feeding component 3 is rectangular and positioned above the weighing assembly 1. The second end of the material feeding component 3 has a through hole 31 that penetrates the material feeding component 3 in the vertical direction, allowing the workpiece to fall from top to bottom into the through hole 31 and onto the weighing assembly 1 for easy weighing.
[0028] All three material frames are set around the weighing component 1. The first rotary drive device 2 can drive the material pusher 3 to rotate in both directions, so that the second end of the material pusher 3 can push the workpiece in the through hole 31 to move towards the corresponding material frame, which is convenient for screening and classifying the workpiece according to its weight.
[0029] Furthermore, the perforation 31 is provided with multiple hole walls, which are connected end to end to form an enclosing structure. In this embodiment, four hole walls are used as an example. The four hole walls enclose a rectangular structure to prevent the workpiece from falling out of the perforation 31 and to ensure that the workpiece can be accurately moved during material feeding.
[0030] The weighing component 1 is provided with a weighing area, which corresponds vertically to the perforation 31. The shape of the weighing area matches the shape of the perforation 31. In this embodiment, the weighing area is preferably rectangular, and the length and width of the weighing area are equal to the length and width of the perforation 31, respectively. Alternatively, the length and width of the weighing area are slightly larger than the length and width of the perforation 31, respectively.
[0031] In this embodiment, the three material frames are a first material frame 4, a second material frame 5, and a third material frame 6, wherein the first material frame 4 and the second material frame 5 are both arranged on the first side of the weighing component 1 and are adjacent to each other;
[0032] A first slide 7 is provided between the weighing component 1 and the first material frame 4 and the second material frame 5. The upper part of the first slide 7 is located on the edge of the weighing component 1, and the lower part of the first slide 7 is connected to both the first material frame 4 and the second material frame 5. A switching component 8 and two material dropping channels are provided inside the first slide 7. The two material dropping channels are connected to the first material frame 4 and the second material frame 5 respectively. The switching component 8 can open one material dropping channel and simultaneously block the other material dropping channel to achieve switching between the two material dropping channels.
[0033] The switching assembly 8 includes a lever 81, a rotating shaft 82, and a second rotary drive device 83. The rotating shaft 82 is located on the lower part of the first slide 7 and at the middle of its width. The lower part of the lever 81 is sleeved on the rotating shaft 82, and the upper part of the lever 81 extends obliquely upwards along the sliding surface of the first slide 7 towards its entrance. The lever 81 divides the interior of the first slide 7 into two material discharge channels, which are respectively located on both sides of the lever 81. The second rotary drive device 83 is located on the outer bottom of the first slide 7. The driving end of the second rotary drive device 83 is connected to the rotating shaft 82, and the second rotary drive device 83 can drive the rotating shaft 82 and the lever 81 to rotate in both directions, allowing the upper part of the lever 81 to swing back and forth between the two sides of the entrance of the first slide 7.
[0034] When the upper part of the lever 81 swings to the left of the inlet, the right-side material drop channel is opened, and the workpiece can enter the first material frame 4 through the right-side material drop channel; when the upper part of the lever 81 swings to the right of the inlet, the left-side material drop channel is opened, and the workpiece can enter the second material frame 5 through the left-side material drop channel.
[0035] The third material frame 6 and the second material frame 5 are respectively arranged on adjacent sides of the weighing component 1. A second slide 9 is provided between the weighing component 1 and the third material frame 6. The upper part of the second slide 9 is located on the edge of the weighing component 1, and the lower part of the second slide 9 is connected to the third material frame 6. The second slide 9 and the first slide 7 are respectively arranged on adjacent sides of the weighing component 1. Specifically, the second slide 9 and the first slide 7 are respectively arranged on the left and right sides of the first rotary drive device 2. The material feeding component 3 can rotate back and forth between the first slide 7, the weighing component 1, and the second slide 9.
[0036] When the feeding component 3 rotates to the right, it can push the workpiece into the first slide 7; when the feeding component 3 rotates to the left, it can push the workpiece into the second slide 9.
[0037] The weighing and screening mechanism in this embodiment also includes a control module (not shown in the figure), which is connected to the weighing component 1, the first rotary drive device 2, and the second rotary drive device 83. After the weighing component 1 weighs the material, the control module selects a suitable material frame 4 according to the weighed weight and drives the material feeding component 3 to turn left or right. When the material feeding component 3 turns right, the control module can also control the second rotary drive device 83 to turn left or right to ensure that the workpiece falls into the appropriate material feeding channel.
[0038] See Figure 4 and combined Figure 2 The weighing assembly 1 includes a base plate 11, a weighing sensor 12, a support plate 13, a tray 14, and a cover 15.
[0039] A load cell 12 is mounted on a base plate 11, and a tray 13 is mounted on the load cell 12 for weighing. A pallet 14 is detachably mounted on the tray 13 for direct contact with the workpiece. A cover 15 is a hollow rectangular frame structure that covers the base plate 11. A rectangular clearance hole 151 is provided in the middle of the cover 15, and the pallet 14 is exposed in the clearance hole 151, allowing the workpiece to fall onto the pallet 14, which serves as the weighing area. The top surface of the pallet 14 is flush with the surface of the cover 15, facilitating material feeding by the material feeder 3.
[0040] The pallet 14 is provided with a bending portion 141 on at least its adjacent two sides. The bending portion 141 protrudes downward from the bottom wall of the pallet 14. When the pallet 14 is placed on the pallet 13, the bending portion 141 is located on the outside of the pallet 13. The bending portion 141 can stop against the side wall of the pallet 13, thereby restricting the horizontal movement of the pallet 14.
[0041] The weighing and screening mechanism in this embodiment can screen and classify workpieces according to their weight and store them separately. It can also be used to select defective products to improve product quality.
