Description

Technical Field

[0001] This invention relates to the field of screen door manufacturing technology, and in particular to a magnet feeding mechanism. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] In the prior art, magnetic screen doors include two symmetrically arranged mesh sheets of equal width, with several magnetic blocks symmetrically arranged from top to bottom on the two adjacent edges of the two mesh sheets. To improve the production efficiency of screen doors, patent application number 202010782652.0 discloses an automated production system for magnetic soft screen doors. This system uses flexible strip magnetic strips, which are rolled into a roll, and then cut into individual magnetic strip segments by a magnetic strip cutting unit.

[0004] However, the above method is only suitable for flexible strip magnetic strips and not for loading rigid magnetic blocks. For rigid magnetic blocks, they can only be placed in a magnetic block storage box, and then pushed out of the storage box one by one by a pusher plate to achieve loading (see the above patent). However, the magnetic block storage box can only store a small amount at a time, requiring frequent replenishment, which is quite cumbersome. Therefore, this application proposes a magnetic loading mechanism to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a magnet feeding mechanism.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A magnet feeding mechanism, comprising: An unwinding mechanism is provided on which a magnet roll is placed. The magnet roll is composed of multiple magnetic blocks. The sides of the multiple magnetic blocks are magnetically attracted together to form a long strip of magnetic strip. The long strip of magnetic strip is then coiled into a magnet roll. The unwinding mechanism is capable of unwinding the magnet roll. The feed chute is used to guide the trajectory of the unwound magnetic strip; The traction mechanism is used to pull and propel the magnetic strip within the feed trough. The feeding mechanism, located at the output end of the feed chute, is used to separate the magnetic block from the magnetic strip and output the magnetic block.

[0007] Furthermore, the unwinding mechanism includes a support part and a servo motor. The magnet roll is placed on the support part, and the servo motor is used to drive the support part to rotate, thereby actively unwinding the magnet roll.

[0008] Furthermore, the support includes an unwinding shaft located at the top of the guide trough, the magnetic roll is mounted on the unwinding shaft, the servo motor drives the unwinding shaft to rotate, and the magnetic strip unwound from the magnetic roll can extend downward under the action of gravity.

[0009] Furthermore, the unwinding shaft has a sleeve, on which an initial magnet is fixed. The magnet is wound around the sleeve, and a magnetic block located at the inner end of the magnet winding is magnetically attracted to the initial magnet.

[0010] Furthermore, the guide trough includes a first guide portion and a second guide portion. One end of the first guide portion is located at the unwinding mechanism, and the other end is located at the second guide portion. The first guide portion is used to receive the downwardly extending magnetic strip and guide the magnetic strip to the second guide portion. The second guide portion is linear and is used to output the magnetic strip in a linear manner.

[0011] Furthermore, the first guide portion is provided with an upward-facing groove, and the magnetic strip is positioned at the corresponding groove position, allowing it to hang down into the groove under the action of gravity. When the traction mechanism pulls the magnetic strip, it can move the magnetic strip hanging down into the groove away from the bottom of the groove. A photoelectric sensor is provided below the groove, and a clearance groove is provided at the bottom of the groove corresponding to the position of the photoelectric sensor. The photoelectric sensor can measure the change in the distance between the magnetic strip in the groove and the bottom of the groove. It also includes a control processor, which is electrically connected to a servo motor and a photoelectric sensor. The control processor is used to control the servo motor to drive the unwinding shaft to rotate when the magnetic strip in the groove moves away from the bottom of the groove, and to control the servo motor to stop operating when the magnetic strip falls to the bottom of the groove.

[0012] Furthermore, the traction mechanism is located at the second guide section and includes a conveyor belt structure located below the second guide section and a pressure roller located above the second guide section; The bottom of the second guide section is provided with a clearance groove. The conveyor belt structure is arranged parallel to the second guide section. The conveyor belt in the conveyor belt structure passes through the clearance groove and contacts the bottom of the magnetic strip. The pressure roller presses down on the top of the magnetic strip from top to bottom, and works with the conveyor belt structure to pull the magnetic strip.

[0013] Furthermore, the pushing mechanism includes: A pusher block is installed at the output end of the feed chute. The pushing component is used to drive the pusher block to reciprocate in a direction perpendicular to the magnetic strip.

[0014] Furthermore, the pushing mechanism also includes a slide bar, the push block is slidably engaged with the slide bar, and the pushing component includes a connecting rod, an eccentric wheel and a power component. One end of the connecting rod is rotatably connected to the push block and the other end is rotatably connected to the eccentric wheel. The power component is used to drive the eccentric wheel to rotate, thereby driving the push block to reciprocate on the slide bar.

[0015] Furthermore, the output end of the guide trough is provided with a discharge trough, and the width of the magnetic block is A, and the width of the discharge trough is B, then A≦B<2A; The pusher block is used to push the magnetic block in the discharge trough, and the pusher block does not detach from the discharge trough during the process of pushing the magnetic block, preventing the magnetic block in the guide trough from entering the discharge trough, until the pusher block is reset.

[0016] Furthermore, the tensioned mesh passes through the bottom of the guide chute, and the pushing direction of the pushing mechanism is consistent with the moving direction of the mesh, pushing the corresponding magnetic block to the top surface of the mesh; It also includes a support plate for supporting the mesh fabric passing under the guide chute. The support plate has elongated magnetic elements at the positions of the corresponding magnetic blocks. The magnetic elements are distributed along the moving direction of the mesh fabric and the relative position of the magnetic blocks and the mesh fabric is limited by magnetic force during the movement of the mesh fabric.

[0017] The beneficial effects of this invention are reflected in: This application, through the use of magnetic rolls, can supply a large number of magnetic blocks at once, eliminating the need for frequent feeding and replenishment, reducing workload, and significantly improving work efficiency.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1-4 As shown, the present invention discloses a magnet feeding mechanism, comprising: The unwinding mechanism 2 has a coiled magnet roll (not shown in the figure) placed on it. The magnet roll is composed of multiple magnetic blocks 11. The sides of the multiple magnetic blocks 11 are magnetically attracted together to form a long strip of magnetic strip 1. Then the long strip of magnetic strip 1 is coiled into a magnet roll. The unwinding mechanism can unwind the magnet roll. The guide groove 3 is used to guide the travel trajectory of the unwound magnetic strip 1; The traction mechanism 4 is used to pull and push the magnetic strip 1 to move within the guide trough 3; The feeding mechanism 5 is located at the output end of the guide trough 3 and is used to separate the magnetic block 11 from the magnetic strip 1 and output the magnetic block 11.

[0022] In practice, multiple magnetic blocks 11 (rectangular magnetic blocks 11 for screen doors) can be manually attracted together by their long sides to form a long magnetic strip 1. This long magnetic strip 1 is then coiled into a magnet roll, which is placed on the unwinding mechanism 2. Initially, one end of the magnetic strip 1 is manually guided into the guide trough 3 and brought into contact with the traction mechanism 4. During operation, the traction mechanism 4 pulls the magnetic strip 1 to unwind and pushes it within the guide trough 3. When one of the magnetic blocks 11 moves to the output end of the guide trough 3, the pushing mechanism 5 is activated, separating the magnetic block 11 from the magnetic strip 1 and outputting the magnetic block 11.

[0023] This invention, through the use of magnetic rolls, can supply a large number of magnetic blocks 11 at once, eliminating the need for frequent feeding and replenishment, thus reducing workload.

[0024] Preferably, the portions of the guide trough 3, traction mechanism 4, and pusher mechanism 5 near the magnetic block 11 are made of a material that does not generate attraction with the magnet, such as plastic, wood, wood-plastic composite, or aluminum.

[0025] In one embodiment, considering that relying solely on the traction mechanism 4 to unwind the magnetic strip 1 can easily cause two adjacent magnetic blocks 11 that are magnetically attracted together to separate, thus breaking the magnetic strip 1, this application adopts the following technical solution: The unwinding mechanism 2 includes a support part and a servo motor 22. The magnet roll is placed on the support part, and the servo motor 22 is used to drive the support part to rotate and actively unwind the magnet roll.

[0026] In specific implementation, the servo motor 22 is equipped with a servo control system. The servo motor 22 can control the rotation angle of the support part according to the diameter of the magnet roll and the width of the magnetic block 11. For example, the diameter of the magnet roll and the width of the magnetic block 11 are pre-input into the servo control system, and the rotation angle of the support part corresponding to each output magnetic block 11 is calculated. In the early stage, the rotation angle of the support part is small. As the magnet roll is continuously unwound, the diameter of the magnet roll is continuously reduced, and the rotation angle of the support part at one time gradually increases.

[0027] Since the servo motor 22 and the servo control system are both very mature existing technologies and common knowledge to those skilled in the art, they will not be described in detail here.

[0028] In one embodiment, to further reduce the difficulty of unwinding, the following technical solution is adopted: The support includes an unwinding shaft 21, which is located at the top of the guide trough 3. The magnet roll is mounted on the unwinding shaft, and the servo motor 22 is used to drive the unwinding shaft 21 to rotate. The magnetic strip 1 unwound from the magnet roll can extend downward under the action of gravity.

[0029] During operation, the unwinding shaft 21 rotates, and the magnet roll rotates accordingly. Under the action of gravity, the unwound magnetic strip 1 extends downward, preventing the magnetic strip 1 from always being attracted to the outside of the magnet roll and unable to extend out from the magnet roll.

[0030] In one embodiment, a sleeve 23 is slidably fitted onto the unwinding shaft 21. An initial magnet 24 is fixed on the sleeve 23. A magnetic block 11, which is wound around the sleeve 23 and located at the inner end of the magnet roll, is magnetically attracted to the initial magnet 24. This magnetic block 11 is used to distinguish the magnetic poles of the magnet roll from the magnetic poles of the magnet roll, ensuring that the magnetic poles are consistent when multiple magnet rolls are wound and when changing the material tray. With this design, the sleeve 23 facilitates the loading and unloading of magnet rolls on the unwinding shaft 21, and the initial magnet 24, based on the principle of opposite poles attracting, makes the loading and unloading of magnet rolls more convenient and ensures that the magnetic poles are consistent when the magnetic block is output.

[0031] In one embodiment, the guide groove 3 includes a first guide portion 31 and a second guide portion 32. One end of the first guide portion 31 is located at the unwinding mechanism 2, and the other end is located at the second guide portion 32. The first guide portion 31 is used to receive the downwardly extending magnetic strip 1 and guide the magnetic strip 1 to the second guide portion 32, so as to avoid the suspended part of the magnetic strip 1 being too long and breaking the magnetic strip 1. The second guide section 32 is linear and is used to make the magnetic strip 1 output in a linear manner.

[0032] Preferably, one end of the first guide portion 31 corresponding to the second guide portion 32 is inclined downwards. The magnetic strip 1 on the first guide portion 31 can automatically slide towards the second guide portion 32 under the action of gravity. In this way, when the traction mechanism 4 pulls the magnetic strip 1 in the second guide portion 32 off, the subsequent magnetic strip 1 can automatically connect the broken magnetic strip 1 under the action of gravity, without affecting the subsequent normal operation. The straight second guide portion 32 can prevent the magnetic strip 1 from breaking when the magnetic block 11 separates from the magnetic strip 1.

[0033] In one embodiment, the first guide portion 31 is provided with an upward-facing groove 311. The magnetic strip 1 is positioned corresponding to the groove 311 and can hang down into the groove 311 under the action of gravity. When the traction mechanism 4 pulls the magnetic strip 1, it can move the magnetic strip 1 hanging down into the groove 311 away from the bottom of the groove 311. A photoelectric sensor 6 is provided below the groove 311, and a clearance groove 312 is provided at the bottom of the groove 311 at the position corresponding to the photoelectric sensor 6. The photoelectric sensor 6 can measure the change in distance between the magnetic strip 1 in the groove 311 and the bottom of the groove 311. It also includes a control processor (not shown in the figure), which is electrically connected to the servo motor 22 and the photoelectric sensor 6. When the magnetic strip 1 in the groove 311 moves away from the bottom of the groove 311, the control processor controls the servo motor 22 to drive the unwinding shaft 21 to rotate, and when the magnetic strip 1 hangs down to the bottom of the groove 311, the control processor controls the servo motor 22 to stop operating.

[0034] In practice, simply relying on the servo motor 22 to control the rotation of the unwinding shaft 21 will result in errors. However, with the addition of the photoelectric sensor 6, it is possible to accurately determine whether the length of the magnetic strip 1 released from the magnet roll is too long or too short. If the length of the released magnetic strip 1 is too long, the servo motor 22 can be stopped in time. If the length of the released magnetic strip 1 is too short, the servo motor 22 can be rotated a certain angle more in time.

[0035] This application adopts a flexible conveying structure with a single direction, which avoids damage and breakage of the magnet caused by repeated reversals and collisions.

[0036] In one embodiment, the traction mechanism 4 is located at the second guide section 32 and includes a conveyor belt structure 41 located below the second guide section 32 and a pressure roller 42 located above the second guide section 32; The bottom of the second guide section 32 is provided with a clearance groove 321. The conveyor belt structure 41 is arranged parallel to the second guide section 32. The conveyor belt in the conveyor belt structure 41 passes through the clearance groove 321 and contacts the bottom of the magnetic strip 1. The pressure roller 42 presses down on the top of the magnetic strip 1 from top to bottom, and works with the conveyor belt structure 41 to pull the magnetic strip 1.

[0037] During operation, the conveyor belt structure 41 contacts the magnetic strip 1. With the help of the elasticity of the conveyor belt and the friction between the conveyor belt and the magnetic strip 1, the magnetic strip 1 can be conveyed forward more effectively, so that the force on a certain magnetic block 11 is not too great and the magnetic strip 1 breaks.

[0038] Preferably, the conveyor belt structure 41 is a common belt conveyor structure in the prior art, including two pulleys and a belt sleeved on the outside of the two pulleys. The belt rotates by driving one of the pulleys through a motor.

[0039] In one embodiment, the pushing mechanism 5 includes: Push block 51 is set at the output end of guide chute 3; The pushing component 52 is used to drive the pusher block 51 to reciprocate in a direction perpendicular to the magnetic strip 1.

[0040] Specifically, the pushing mechanism 5 also includes two sliding rods 53. The push block 51 is slidably engaged with the sliding rods 53. The pushing component 52 includes a connecting rod 521, an eccentric wheel 522, and a power component 523. One end of the connecting rod 521 is rotatably connected to the push block 51, and the other end is rotatably connected to the eccentric wheel 522. The power component 523 is used to drive the eccentric wheel 522 to rotate. The push block 51, the connecting rod 521, the eccentric wheel 522, and the power component 523 constitute a crank-slider mechanism, which drives the push block 51 to reciprocate on the sliding rod 53.

[0041] Preferably, a spring 54 is fitted on the slide bar 53. The spring 54 is used to assist the push block 51 in resetting and to prevent the push block 51 from getting stuck on the slide bar 53.

[0042] Preferably, the power component 523 can be a motor as in the prior art.

[0043] It should be noted that the structure of the pushing mechanism 5 can also be designed as an up-and-down pushing structure, pushing the magnetic block 11 downward away from the guide groove 3. However, since this method is less stable than the pushing method described above, it is preferred that the magnetic block 11 is output using the pushing method described above.

[0044] In one embodiment, the output end of the guide groove 3 is provided with a discharge groove 322, and the width of the magnetic block 11 is A, and the groove width of the discharge groove 322 is B, then A≦B<2A; The pusher block 51 is used to push the magnetic block 11 in the discharge trough 322, and the pusher block 51 does not detach from the discharge trough 322 during the process of pushing the magnetic block 11, preventing the magnetic block 11 in the guide trough 3 from entering the discharge trough 322, until the pusher block 51 resets. This can prevent the pusher block 51 from pushing the magnetic block 11 out of the discharge trough 322 in the opposite direction when it resets.

[0045] In one embodiment, the tensioned mesh passes through the bottom of the guide groove 3, and the pushing direction of the pushing mechanism 5 is consistent with the moving direction of the mesh. The pushing mechanism 5 pushes the corresponding magnetic block 11 to the top surface of the mesh. It also includes a support plate 7 for supporting the mesh fabric passing under the guide trough 3. The support plate 7 has a strip-shaped magnetic element 71 at the position of the corresponding magnetic block 11. The magnetic element 71 is distributed along the moving direction of the mesh fabric. The magnetic pole of the magnetic element 71 is different from the magnetic pole of the magnetic block 11. During the movement of the mesh fabric, it attracts the pushed-out magnetic block 11 to limit the relative position of the magnetic block 11 and the mesh fabric.

[0046] In practice, the pushing mechanism 5 pushes the magnetic blocks 11 one by one to the top surface of the mesh fabric. At this time, the magnetic component 71 and the magnetic blocks 11 generate an attractive force. The mesh fabric is sandwiched between the magnetic component 71 and the magnetic blocks 11. When the mesh fabric moves, it drags the magnetic blocks 11 forward. Under the constraint of the magnetic component 71, the magnetic blocks 11 are not easy to be displaced from the mesh fabric. In this way, the relative position between the mesh fabric and the magnetic blocks 11 in the moving state can be determined, which makes it convenient to wrap the mesh fabric and wrap the magnetic blocks 11 on the mesh fabric.

[0047] Specifically, the device for edge-wrapping the mesh fabric is disposed on the side of the magnetic component 71 along the extension direction of the magnetic component 71, and edge-wrappes the mesh fabric during the mesh fabric making process. Since the device for edge-wrapping the mesh fabric is a mature existing technology and common knowledge to those skilled in the art, it will not be described in detail here. Only a solution for limiting the relative position of the magnetic block 11 and the mesh fabric is provided here.

[0048] It should be noted that the magnetic force of the magnetic component 71 is not large, so it will not cause the mesh to be unable to drag the magnetic block 11. Preferably, the magnetic component 71 can be a permanent magnet or an electromagnet, with an electromagnet being preferred. The magnetic force generated by the electromagnet can be adjusted by controlling the magnitude of the current.

[0049] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0050] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0051] Additionally, "multiple" refers to two or more.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
