Description

Technical Field

[0001] This invention relates to the field of hinge manufacturing technology, and more particularly to a screw feeding mechanism for a hinge packaging box device. Background Technology

[0002] When packaging hinges, screws are bagged together with the hinges for user convenience. To prevent the screws from being lost, the screws are also packaged in bags.

[0003] In existing technologies, material supply often uses vibrating feeders. However, using a vibrating feeder alone makes it difficult to stably supply bagged screws to the hinge packaging device, which is prone to omissions or quantity overflows, resulting in a decrease in yield. If a mechanical gripper is used to grab the bagged screws from the output port of the vibrating feeder, the mechanical gripper not only has difficulty effectively grabbing the bagged screws independently, but also, because the screws are sharp and irregular objects, the mechanical gripper is very likely to damage the packaging bag of the screws when grabbing them, resulting in a decrease in yield. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies in that it is difficult to separate and feed bagged screws, and to propose a screw feeding mechanism for a hinge packing box device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a screw feeding mechanism for a hinge packing box device, including a vibrating feeding plate, the discharge port of which is connected to a guide chute, and a partition belt conveyor located on one side of the guide chute, and further including:

[0007] A magnetic material transfer assembly includes a first slide rail device, a second slide rail device mounted on the free end of the first slide rail device, an mounting plate mounted on the free end of the second slide rail device, a push cylinder mounted on the outer end face of the mounting plate, a contact plate sleeved on the telescopic rod of the push cylinder, a permanent magnet nested inside the contact plate, and a limit push plate mounted on the lower end of the mounting plate, the lower end of the limit push plate being bent below the permanent magnet.

[0008] Preferably, a spring is elastically connected between the contact plate and the mounting plate, and in its natural state, the spring pushes the contact plate close to the limiting push plate.

[0009] Preferably, the limiting push plate has a through hole at one end below the permanent magnet to reduce the obstruction between the permanent magnet and the material directly below it. The contact plate is wrapped with a rubber layer. The limiting push plate has an "L" shaped structure, and the bent part of the limiting push plate is away from the output port of the guide trough.

[0010] Preferably, sensing devices are installed on both the left and right sides of the partition belt conveyor. The sensing devices are used to sense whether there is material between two adjacent sets of partition plates of the partition belt conveyor.

[0011] Preferably, the system also includes a belt weighing machine, with a discharge slide plate and a waste slide plate respectively located on the left and right sides of the belt weighing machine in the direction of travel, a feed slide plate located above the belt weighing machine for receiving materials, a waste bin located below the waste slide plate, and the discharge slide plate extending above the partition belt conveyor.

[0012] Preferably, the output port of the discharge slide plate has a narrowing structure.

[0013] The present invention provides a screw feeding mechanism for a hinged box-packing device, which has the following advantages:

[0014] A push cylinder is mounted on the outer end face of the mounting plate, and a contact plate is sleeved on the telescopic rod of the push cylinder. A permanent magnet is nested inside the contact plate. A limit push plate is mounted on the lower end of the mounting plate, and the lower end of the limit push plate is bent below the permanent magnet. When picking up materials, the lower end of the limit push plate is first brought close to the material. Then, the push cylinder is activated. The telescopic rod of the push cylinder drives the contact plate and the permanent magnet to approach the lower end of the limit push plate and the material. At this time, the material is magnetically attracted and remains in contact with the limit push plate. The material adheres well to the contact plate. During feeding, the push cylinder is activated, pushing the cylinder's extension rod to move the contact plate and permanent magnet away from the lower end of the limit push plate. At this time, the magnetic attraction strength of the material decreases, and the material falls by itself. The limit push plate prevents the permanent magnet from attracting the material laterally, thus ensuring that the permanent magnet can only attract one group of materials at a time, achieving material separation. The limit push plate also reduces the squeezing and friction on the material, preventing damage to the packaging bag and facilitating the release of the material from the magnetic attraction of the permanent magnet.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Example 1

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 A screw feeding mechanism for a hinge packing box device includes a vibrating feeding plate 1, the discharge port of the vibrating feeding plate 1 being connected to a guide trough 2, a partition belt conveyor 8 being provided on one side of the guide trough 2, and further includes:

[0024] Magnetic material transfer assembly, see reference Figure 3 The magnetic material transfer assembly includes a first slide rail device 11, a second slide rail device 12 installed at the free end of the first slide rail device 11, an mounting plate 13 installed at the free end of the second slide rail device 12, a push cylinder 14 installed on the outer end face of the mounting plate 13, a contact plate 17 sleeved on the telescopic rod of the push cylinder 14, a permanent magnet 18 nested inside the contact plate 17, a limit push plate 15 installed at the lower end of the mounting plate 13, and the lower end of the limit push plate 15 bent to the bottom of the permanent magnet 18. The magnetic material transfer assembly is provided in two sets. One set of magnetic material transfer assembly is set between the guide trough 2 and the partition belt conveyor 8, and the other set of magnetic material transfer assembly is set on the discharge side of the partition belt conveyor 8.

[0025] Furthermore, refer to Figure 3 A spring 19 is elastically connected between the contact plate 17 and the mounting plate 13. In its natural state, the spring 19 pushes the contact plate 17 close to the limit push plate 15.

[0026] Furthermore, refer to Figure 3The limiting push plate 15, located below the permanent magnet 18, has a through hole 16 at one end. The through hole 16 reduces the obstruction between the permanent magnet 18 and the material directly below it. The contact plate 17 is wrapped with a rubber layer. The limiting push plate 15 has an "L"-shaped structure, with the bent part of the limiting push plate 15 away from the output port of the guide trough 2. The rubber layer reduces the friction intensity between the material passing through the through hole 16 and the contact plate 17 in localized areas, preventing damage to the material surface. By keeping the bent part of the limiting push plate 15 away from the output port of the guide trough 2, it can laterally block the material behind the guide trough 2, reducing the magnetic attraction strength of the permanent magnet 18 to the material behind it. (Reference) Figure 3 The permanent magnet 18 can also be nested on the side of the contact plate 17 away from the bending area of ​​the limiting push plate 15, so as to further reduce the magnetic attraction strength of the permanent magnet 18 to the lateral material.

[0027] Furthermore, refer to Figure 5 The partition belt conveyor 8 is equipped with sensing devices 10 on both the left and right sides. The sensing devices 10 are used to sense whether there is material between two adjacent sets of partition plates 9 of the partition belt conveyor 8.

[0028] Working principle:

[0029] Reference Figure 3 The free end of the first slide rail device 11 can drive the second slide rail device 12 to move laterally, and the free end of the second slide rail device 12 can drive the mounting plate 13 to move vertically. Through the cooperation of the first slide rail device 11 and the second slide rail device 12, the mounting plate 13 can move laterally and vertically. The telescopic rod of the push cylinder 14 can drive the contact plate 17 and the permanent magnet 18 away from or close to the lower end of the limit push plate 15. The lower end surface of the limit push plate 15 can directly contact the material. When the telescopic rod of the push cylinder 14 drives the contact plate 17 and the permanent magnet 18 close to the limit push plate 15, the lower end surface of the limit push plate 15 can directly contact the material. When the material is at the lower end of the plate 15, it adheres to the lower end face of the limiting push plate 15 under the magnetic attraction of the permanent magnet 18. When the extension rod of the pushing cylinder 14 drives the contact plate 17 and the permanent magnet 18 away from the lower end of the limiting push plate 15, the magnetic attraction of the permanent magnet 18 to the material weakens, and the material separates from the lower end face of the limiting push plate 15, thereby achieving the effect of "grabbing" and "releasing". Through the limitation of the limiting push plate 15, the permanent magnet 18 can only attract the material directly below it each time, and cannot attract the material laterally, thus realizing the use requirement of transferring a group of materials at a time.

[0030] Based on the above principle, the material transfer between the guide trough 2 and the partition belt conveyor 8 is as follows: Control the first slide rail device 11, which causes the permanent magnet 18 and the limiting push plate 15 to move laterally to above the outermost group of materials in the guide trough 2; Control the second slide rail device 12, which causes the permanent magnet 18 and the limiting push plate 15 to move downward, and the lower end face of the limiting push plate 15 contacts the material; Control the pushing cylinder 14, which causes the permanent magnet 18 and the contact plate 17 to approach the through hole 16 opened on the limiting push plate 15. At this time, the material located directly below the limiting push plate 15 will be magnetically attracted by the permanent magnet 18 and kept in contact with the limiting push plate 15, thus completing the material picking action;

[0031] After material collection is completed, the first slide rail device 11 and the second slide rail device 12 are controlled again to move the permanent magnet 18, the limiting push plate 15, and the material to the top of the partition belt conveyor 8 and between two adjacent sets of partition plates 9 on the partition belt conveyor 8. The push cylinder 14 is controlled to push the permanent magnet 18 and the contact plate 17 away from the through hole 16 opened on the limiting push plate 15. The material cannot move upward with the permanent magnet 18 due to the obstruction of the limiting push plate 15. At this time, the magnetic attraction of the permanent magnet 18 to the material weakens, and the material leaves the limiting push plate 15 and falls down onto the partition belt conveyor 8. When the sensing device 10 set on the partition belt conveyor 8 detects that there is material between two adjacent sets of partition plates 9, the partition belt conveyor 8 is started and the material is transported to the existing hinged packaging box device.

[0032] Material transfer between the partition belt conveyor 8 and the existing hinged packing box device: Control the first slide rail device 11, which moves the permanent magnet 18 and the limiting push plate 15 to the top of the partition belt conveyor 8 and between two adjacent sets of partition plates 9 on the partition belt conveyor 8; Control the second slide rail device 12, which moves the permanent magnet 18 and the limiting push plate 15 downward, and the lower end face of the limiting push plate 15 contacts the material; Control the pushing cylinder 14, which makes the permanent magnet 18 and the contact plate 17 approach the through hole 16 opened on the limiting push plate 15. At this time, the material located directly below the limiting push plate 15 will be magnetically attracted by the permanent magnet 18 and kept in contact with the limiting push plate 15, thus completing the material picking action;

[0033] After the material is picked up, the first slide rail device 11 and the second slide rail device 12 are controlled again to move the permanent magnet 18, the limiting push plate 15, and the material to the required position of the existing hinged packaging box device. The push cylinder 14 is controlled to push the permanent magnet 18 and the contact plate 17 away from the through hole 16 opened on the limiting push plate 15. The material cannot move upward with the permanent magnet 18 due to the obstruction of the limiting push plate 15. At this time, the magnetic attraction of the permanent magnet 18 to the material weakens, and the material is separated from the limiting push plate 15 and falls downward to the required position of the existing hinged packaging box device, thus completing the material transfer action.

[0034] Example 2

[0035] To further improve the success rate of transferring a group of materials in a single operation and to conduct quality inspection of the materials, refer to Figure 1 , Figure 4 It also includes a belt weighing machine 3, with a discharge slide plate 5 and a waste slide plate 6 respectively located on the left and right sides of the belt weighing machine 3 in the direction of travel. A feed slide plate 4 is located above the belt weighing machine 3 for receiving materials. A waste box 7 is located below the waste slide plate 6. The discharge slide plate 5 extends above the partition belt conveyor 8.

[0036] Furthermore, refer to Figure 4 The output port of the discharge slide plate 5 has a narrowing structure.

[0037] Working principle:

[0038] The difference from the "material transfer between the guide chute 2 and the partition belt conveyor 8" in Embodiment 1 is that, in this embodiment, after the material is picked up, the first slide rail device 11 and the second slide rail device 12 move the permanent magnet 18, the limiting push plate 15, and the material to the top of the feed slide plate 4. The material slides down the feed slide plate 4 onto the belt weighing machine 3, where it is weighed. When the material weighs up to the required level, the belt weighing machine 3 moves the material toward the discharge slide plate 5, where it slides down to the two adjacent partition plates 9 on the partition belt conveyor 8. When the material weighs down to the required level, the belt weighing machine 3 moves the material toward the waste slide plate 6, where it slides down into the waste bin 7. This completes the material inspection. Even if the permanent magnet 18 magnetically attracts two sets of materials, the belt weighing machine 3 can detect the weight abnormality and transfer the material to the waste bin 7 for processing.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
