Description

Technical Field

[0001] The present application relates to the technical field of loop forming machines, and in particular to a fan mesh cover wire loop forming machine. Background Art

[0002] Fan guard, also known as fan guard or fan protective guard, is a protective device used to protect air conditioners, motors, exhaust fans, radiators, fans, generators, diesel engines and other equipment to ensure the normal operation of their heat dissipation, exhaust and ventilation functions. The fan guard includes multiple guard rings of different radius sizes, which are made of steel wire through a looping machine.

[0003] The existing Chinese patent with publication number CN213559676U discloses an automatic circle making machine, including a circle making device and a circle collecting device; the circle collecting device is fixedly connected to the outer surface of the circle making device; the circle collecting device includes a mounting base plate and a ring device; a plurality of the ring devices are fixedly connected to the upper surface of the mounting base plate, a ring connecting rod is sleeved on the outer surface of the ring device, and one end of the ring connecting rod is rotatably connected to the outer surface of the circle making device through a hinge.

[0004] The cut and formed wire material slides onto the ferrule device through the ferrule rod. After the ferrule device is full, the movable rod is rotated to remove the movable rod from the inside of the connecting sleeve. The ferrule rod is placed on another ferrule device through a hinge to continue production, so as to avoid the coil falling on the ground and being inconvenient to sort out. The ferrule device is used as the center of the coil, which is convenient for the staff to sort out the coil and improve the work efficiency of the staff. However, the above-mentioned automatic coiling machine still has some disadvantages, such as: after the ferrule device is full, the movable rod needs to be rotated to remove the movable rod from the inside of the connecting sleeve. Since the movable rod is threadedly connected to the ferrule sleeve, it is difficult to rotate the movable rod manually or with the help of a tool, which is troublesome and affects the efficiency of replacing the ferrule rod to another movable rod, which needs to be improved. Utility Model Content

[0005] The purpose of the present application is to provide a fan mesh cover wire loop forming machine to improve the efficiency of replacing the connecting rod to another support rod.

[0006] A fan mesh wire loop forming machine provided in the present application adopts the following technical solution: it includes a frame, the frame is connected with a looping mechanism, a loop connecting rod and at least two support rods, each of the support rods is slidably connected with a connecting rod, one end of the loop connecting rod is rotatably connected to the frame, the connection between the loop connecting rod and the frame corresponds to the looping mechanism, each of the support rods is provided with a collecting piece, the connecting rod is provided with an installation groove for the other end of the loop connecting rod to be clamped in, and the connecting rod is connected with a fixing mechanism for limiting the loop connecting rod from being separated from the installation groove.

[0007] By adopting the above technical solution, when the collar rod needs to be replaced onto another support rod, the fixing mechanism no longer restricts the collar rod, and the connecting rod can move relative to the collar rod, enabling the collar rod to disengage from the mounting groove on the connecting rod, thereby improving the efficiency of the collar rod disengaging from the mounting groove. Rotate the collar rod so that the end of the collar rod away from the frame aligns with the mounting groove on another connecting rod, and move the connecting rod in the direction close to the collar rod, so that one end of the collar rod is snapped into the mounting groove of the connecting rod. The fixing mechanism on the connecting rod restricts the collar rod from disengaging from the mounting groove, improving the installation efficiency of the collar rod, that is, improving the efficiency of replacing the collar rod onto another support rod.

[0008] Optionally, the fixing mechanism includes at least two fixing blocks slidably connected to the connecting rod and an active assembly for driving the fixing blocks to slide in the direction close to or away from the collar rod. The active assembly is connected to the connecting rod, and the collar rod is provided with a fixing area for the fixing blocks to snap into.

[0009] By adopting the above technical solution, when the collar rod needs to be replaced onto another support rod, the active assembly drives the fixing blocks to slide in the direction away from the collar rod, so that the fixing blocks disengage from the fixing area, thereby realizing the separation of the collar rod and the connecting rod. When one end of the collar rod is snapped into the mounting groove of another connecting rod, when the fixing blocks in the connecting rod correspond to the fixing area, the active assembly in the connecting rod drives the fixing blocks to slide in the direction close to the collar rod, so that the fixing blocks snap into the fixing area. The fixing blocks play a role in restricting the movement of the connecting rod relative to the collar rod, thereby improving the installation stability between the connecting rod and the collar rod.

[0010] Optionally, the fixing block is a fixing bead. The connecting rod is provided with a channel for slidably cooperating with the fixing bead. The channel communicates with the mounting groove. The active assembly includes a first elastic member and an active ring slidably connected to the connecting rod. One end of the first elastic member is connected to the connecting rod, and the other end is connected to the active ring. The active ring is provided with a yielding cavity for the fixing bead to snap into, and the inner wall of the yielding cavity is provided with a guiding surface for abutting against the fixing bead.

[0011] By adopting the above technical solution, when the connecting rod needs to be replaced on another connecting rod, the active ring is first moved in the direction away from the connecting rod so that the fixed bead corresponds to the clearance cavity. Then the connecting rod is moved in the direction away from the connecting rod, the connecting rod and the connecting rod move relative to each other, the connecting rod drives the fixed bead to leave the fixed area, and part of the fixed bead is stuck in the clearance cavity. Only the active ring and the connecting rod need to be moved, and the connecting rod and the connecting rod can be separated, thereby improving the efficiency of separation between the connecting rod and the connecting rod. When the connecting rod is stuck in the installation groove of another connecting rod, the active ring is released, the first elastic member is elastically reset, the first elastic member forces the active ring to reset, the guide surface abuts against the fixed bead and drives the fixed bead to be stuck in the fixed area, thereby improving the efficiency of installation between the connecting rod and the connecting rod.

[0012] Optionally, the radius of the opening of the channel close to the mounting groove is smaller than the radius of the fixing bead.

[0013] By adopting the above technical solution, the fixing bead is prevented from being separated from the connecting rod through the opening of the channel close to the installation groove during movement, thereby improving the stability of the fixing bead moving on the connecting rod.

[0014] Optionally, the fixing area is a fixing ring groove arranged on the connecting ring rod.

[0015] By adopting the above technical solution, the fixing beads on the connecting rod can be inserted into the fixing ring groove, and the connecting rod will not drive the connecting rod to rotate when compared with the connecting rod.

[0016] Optionally, the collecting member includes a vertical rod and a placement plate connected to one end of the vertical rod, the vertical rod is provided with a through hole for slidingly cooperating with the support rod, and the through hole passes through the placement plate.

[0017] By adopting the above technical solution, the steel wire is cut by the looping mechanism to form a cover ring, and the cover ring falls on the placement plate along the length direction of the ring rod under the influence of gravity to complete the stacking. When one of the placement plates is stacked, moving the corresponding vertical rod can drive the placement plate and the cover ring on the placement plate to move together, making it easy to move the cover ring.

[0018] Optionally, the support rod is provided with a receiving groove for slidingly cooperating with the connecting rod, and the connecting rod is connected to the inner wall of the receiving groove via a second elastic member.

[0019] By adopting the above technical solution, the second elastic member supports the connecting rod, thereby improving the stability of the connection between the connecting rod and the connecting ring rod.

[0020] Optionally, the looping mechanism includes a looping die connected to the frame, a cutting assembly, a transmission assembly, and a plurality of guide posts. The cutting assembly is located between the looping die and the transmission assembly. The looping die surrounds the connection between the ring receiving rod and the frame and the plurality of guide posts.

[0021] By adopting the above technical solution, the transmission assembly drives the steel wire to move towards the cutting assembly. The steel wire bends along the looping die and the plurality of guide posts. When one end of the steel wire moves to the corresponding position, the cutting assembly cuts off the steel wire, thus completing the cover ring.

[0022] Optionally, the frame is slidably connected with a ring pushing member. The looping die surrounds the ring pushing member. The ring pushing member surrounds the plurality of guide posts. The frame is connected with a driving member for driving the ring pushing member to slide towards or away from the support rod.

[0023] By adopting the above technical solution, after the steel wire is cut off, the driving member drives the ring pushing member to slide towards the support rod. The ring pushing member abuts against the cover ring and pushes the cover ring to move towards the support rod, facilitating the cover ring to smoothly fall on the placement plate.

[0024] Optionally, the frame is provided with a relief groove for the ring pushing member to snap into.

[0025] By adopting the above technical solution, the ring pushing member snaps into the relief groove, preventing the ring pushing member from affecting the bending of the steel wire along the looping die and the plurality of guide posts.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Move the connecting rod towards the ring receiving rod, so that one end of the ring receiving rod is snapped into the installation groove of the connecting rod. The fixing mechanism on the connecting rod restricts the ring receiving rod from disengaging from the installation groove, improving the installation efficiency of the ring receiving rod, that is, improving the efficiency of replacing the ring receiving rod to another connecting rod.

[0028] 2. The second elastic member plays a role in supporting the connecting rod, improving the stability of the connection between the connecting rod and the ring receiving rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following further describes the present application in detail Figure 1 - with reference to Figure 5 the accompanying drawings.

[0036] An embodiment of the present application discloses a wire loop-forming machine for a fan grille.

[0037] As Figure 1 shown, it includes a frame 1, and the frame 1 is connected with a loop-forming mechanism 2, a loop-receiving rod 3 and three support rods 11 (the number of support rods 11 is selected according to actual needs). The loop-forming mechanism 2 includes a loop-forming die 21 connected to the frame 1, a cutting assembly 22 (the structure and function of the cutting assembly 22 are the same as those of the cutter device in the patent with the publication number CN213559676U, and the cutting assembly 22 is a prior art), a transmission assembly 23 and three guide posts 24. The cutting assembly 22 is located between the loop-forming die 21 and the transmission assembly 23. The transmission assembly 23 includes four transmission disks 231 rotatably connected to the same side of the frame 1 and a motor (not shown in the drawings) for driving the corresponding transmission disk 231 to rotate. The motor is fixedly connected to one side of the frame 1. The number of motors is the same as the number of transmission disks 231. The motor is externally connected with a controller (not shown in the drawings). The signal output end of the controller is connected to the signal input end of the motor. The side of the transmission disk 231 close to the corresponding motor is fixedly connected to the output end of the motor. Every two transmission disks 231 form a group, and each group of transmission disks 231 is distributed vertically opposite to each other. When the transmission disk 231 rotates, the transmission disk 231 abuts against the wire and drives the wire to move towards the direction close to the loop-forming die 21.

[0038] Combined with Figure 1 and Figure 2As shown, the ring grinding tool 21 is in a C shape, and the opening of the ring grinding tool 21 faces the transfer disk 231. Three guide posts 24 are rotatably connected to the frame 1, and the ring grinding tool 21 surrounds the three guide posts 24. The frame 1 is rotatably connected with three connecting posts 12, and the three connecting posts 12 are located between the guide posts 24 and the transfer disk 231. One end of the coil receiving rod 3 is hinged to the frame 1, and the connection point of the coil receiving rod 3 and the frame 1 is the same as the center of the ring grinding tool 21. The ring grinding tool 21 surrounds the connection point of the coil receiving rod 3 and the frame 1. On one side of the frame 1 close to the support rod 11, a push ring 4 is slidably connected. The push ring 4 is in a C shape, and the opening of the push ring 4 faces the transfer disk 231. The ring grinding tool 21 surrounds the push ring 4, and the push ring 4 surrounds the three guide posts 24. The frame 1 is provided with a relief groove 13 for the push ring 4 to be inserted into. The frame 1 is fixedly connected with a driving member (not shown in the drawing) for driving the push ring 4 to slide in a direction close to or away from the support rod 11. The driving member is a cylinder. The signal output end of the controller is connected to the signal input end of the driving member, and one side of the push ring 4 close to the driving member is fixedly connected to the output end of the driving member.

[0039] Combined with Figure 3 and Figure 4 As shown, the support rod 11 is fixedly connected to the frame 1. The three support rods 11 are distributed around the hinge point of the coil receiving rod 3 and the frame 1. When the coil receiving rod 3 rotates, the end of the coil receiving rod 3 away from the frame 1 can correspond to the three support rods 11 respectively. Each support rod 11 is sleeved with a collecting member 5. The collecting member 5 includes a vertical rod 51 and a placing plate 52 fixedly connected to the outer peripheral surface of the vertical rod 51. The placing plate 52 is located at one end of the vertical rod 51. The placing plate 52 is in a cylindrical shape, and the radius size of the placing plate 52 is selected according to actual requirements. The vertical rod 51 is provided with a through hole 511 for sliding cooperation with the support rod 11, and the through hole 511 penetrates the placing plate 52.

[0040] Combined with Figure 4 and Figure 5As shown, one end of the support rod 11 away from the placement plate 52 is slidably connected to a connecting rod 6. The support rod 11 is provided with a receiving groove 111 for slidably cooperating with the connecting rod 6. The connecting rod 6 is connected to the inner wall of the receiving groove 111 through a second elastic member 61. The second elastic member 61 is a spring. One end of the second elastic member 61 is fixedly connected to the inner wall of the receiving groove 111, and the other end is fixedly connected to one end of the connecting rod 6. One end of the connecting rod 6 close to the coil connecting rod 3 is provided with a mounting groove 62 for one end of the coil connecting rod 3 to be inserted into. The connecting rod 6 is connected with a fixing mechanism 7 for restricting the coil connecting rod 3 from disengaging from the mounting groove 62. The fixing mechanism 7 includes four fixing blocks 71 slidably connected to the connecting rod 6 and a driving assembly 72 for driving the four fixing blocks 71 to slide in a direction close to or away from the coil connecting rod 3. The fixing blocks 71 are fixing beads, and the four fixing beads are evenly distributed around the axis of the connecting rod 6. The connecting rod 6 is provided with a channel 63 for slidably cooperating with the corresponding fixing beads. The channel 63 communicates with the mounting groove 62. The radius of the opening of the channel 63 close to the mounting groove 62 is smaller than the radius of the fixing beads. The coil connecting rod 3 is provided with a fixing area 31 for the fixing blocks 71 to be inserted into. The fixing area 31 is a fixing ring groove formed on the outer peripheral surface of the coil connecting rod 3.

[0041] Combined Figure 4 with Figure 5 As shown, the driving assembly 72 includes a first elastic member 721 and a driving ring 722 slidably connected to the outer peripheral surface of the connecting rod 6. The first elastic member 721 is a spring. One end of the first elastic member 721 is fixedly connected to the driving ring 722, and the other end is fixedly connected to the connecting rod 6. The inner ring of the driving ring 722 is provided with a yielding cavity 7221 for a part of the fixing beads to be inserted into. The inner wall of the yielding cavity 7221 is provided with a guiding surface 7222 for abutting against the fixing beads.

[0042] The implementation principle of a wire coiling and forming machine for a fan grille in an embodiment of the present application is as follows:

[0043] When it is necessary to replace the coil connecting rod 3 to another connecting rod 6, first move the driving ring 722 in a direction away from the coil connecting rod 3 so that the fixing beads correspond to the yielding cavity 7221. Then move the connecting rod 6 in a direction away from the coil connecting rod 3. The connecting rod 6 and the coil connecting rod 3 move relatively. The coil connecting rod 3 drives the fixing beads to disengage from the fixing area 31, and a part of the fixing beads is inserted into the yielding cavity 7221. By only moving the driving ring 722 and the connecting rod 6, the coil connecting rod 3 and the connecting rod 6 can be separated, improving the separation efficiency between the coil connecting rod 3 and the connecting rod 6.

[0044] Rotate the connecting ring rod 3 so that the connecting ring rod 3 is aligned with the installation groove 62 of the other connecting rod 6. Loosen the connecting rod 6, and the second elastic member 61 resets elastically. The second elastic member 61 forces the fixing bead to correspond to the fixing area 31. Loosen the driving ring 722, and the first elastic member 721 resets elastically. The first elastic member 721 forces the driving ring 722 to reset. The guiding surface 7222 abuts against the fixing bead and drives the fixing bead to snap into the fixing area 31, thereby realizing the connection between the connecting rod 6 and the connecting ring rod 3 and improving the installation efficiency between the connecting ring rod 3 and the connecting rod 6.

[0045] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
