Description

Technical Field

[0001] This invention relates to the field of speaker grille manufacturing technology, and more specifically, to a speaker grille forming apparatus with a loading and unloading structure. Background Technology

[0002] The stretch forming device for speaker grille production is a specialized piece of equipment. Through the coordinated work of its components, this device solves the problems of surface unevenness or wrinkling that occur during the forming process of speaker grilles, effectively improving the production quality and efficiency. Existing speaker grille stretch forming devices require workers to manually place the grille onto the forming mold surface and then manually remove it after forming. Frequent manual placement and removal of the grille increases the labor intensity for workers, potentially leading to fatigue and reduced work efficiency over time. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a speaker grille forming device with a loading and unloading structure. This solves the problem that existing speaker grille stretching forming devices require workers to manually place the grille on the surface of the forming mold and then manually remove it after forming. Frequent manual placement and removal of the grille increases the labor intensity of workers and may lead to worker fatigue in the long run, thereby reducing work efficiency.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A speaker grille forming device with a loading and unloading structure includes an operating table. A mounting groove is formed on one side surface of the operating table. A through groove is formed on the top surface of the mounting groove. A forming component for grille forming is provided at the bottom of the mounting groove.

[0006] A pressing component for pressing is provided on one side of the upper surface of the operating table;

[0007] Material handling components for material handling are provided on both sides of the upper surface of the operating platform.

[0008] Preferably, the molding component includes several limiting rods, each of which is fixedly installed at the bottom of the mounting groove, and each of the limiting rods has a moving ring sleeved on one side of its body, and a first spring sleeved on the other side of its body.

[0009] A molded sleeve is fixedly installed on the upper surface of the movable ring, and the upper end of the molded sleeve passes through a through groove.

[0010] A molding die is fixedly installed at the bottom of the mounting groove and between each limiting rod.

[0011] Preferably, the pressing assembly includes a support frame, which is fixedly installed on one side of the upper surface of the operating table. A cylinder is fixedly installed on the upper surface of the support frame, and the output end of the cylinder passes through the support frame and is fixedly installed with a pressing mold. A forming cavity is formed on the lower surface of the pressing mold.

[0012] Preferably, the material conveying assembly includes an electric guide rail, which is fixedly installed on one side of the upper surface of the operating table. A vertical plate is fixedly installed on the moving end of the electric guide rail, and a clamping structure for clamping the mesh plate is provided on the side of the vertical plate near the forming cavity.

[0013] Preferably, the clamping structure includes a sliding groove that extends through the surface of the upright plate near the molding cavity. Two sliders are slidably disposed in the sliding groove, and a clamping plate is fixedly installed on the side of the two sliders near the molding cavity.

[0014] A bidirectional lead screw is rotatably installed between the two sides of the inner wall of the slide groove, and the two sliders are respectively threaded on both sides of the bidirectional lead screw.

[0015] A first motor is fixedly installed on one side of the upper surface of the upright plate, and the upper end of the bidirectional lead screw passes through the corresponding upright plate and is fixedly connected to the output shaft end of the first motor.

[0016] Preferably, each of the clamps has a connecting groove extending through both sides of its upper surface, and each connecting groove has a roller movably disposed therein.

[0017] Preferably, each of the adjacent clamping plates is fixedly installed with a support rod on the side away from each other, and each of the adjacent support rods is slidably provided with a movable frame on one side of the rod body. The adjacent rollers are respectively rotatably installed on one side of the corresponding movable frame via a rotating rod.

[0018] A limit plate is fixedly installed at one end of each adjacent support rod;

[0019] A second spring is fitted on the other side of each of the support rods.

[0020] Preferably, a limit plate is fixedly installed at one end of each adjacent support rod.

[0021] Preferably, each of the rotating rods is fitted with a first pulley on one side, and each of the moving frames is provided with two drive structures for driving the corresponding rotating rods to rotate on the side near the forming cavity.

[0022] Preferably, the drive structure includes a fixed frame, which is fixedly installed on a corresponding side of the movable frame. A third motor is fixedly installed on one side of the inner wall of the fixed frame. A second pulley is sleeved on the output shaft of the third motor. A transmission belt is sleeved on the outer wall of the second pulley and the first pulley.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The operator controls the clamping structure to clamp both ends of the mesh plate. Then, the operator controls the electric guide rail to move the clamping structure and the mesh plate to the upper surface of the forming sleeve. After the pressure mold and the forming mold are in contact, the operator controls the clamping structure to disengage from the mesh plate. After the mesh plate is formed into a mesh cover and moves to its original position, the operator controls the clamping structure and the electric guide rail to remove the formed mesh cover from the upper surface of the forming sleeve. This eliminates the need for frequent manual placement and removal of the mesh plate, reducing the labor intensity of workers and thus improving work efficiency.

[0025] 2. When adjacent clamps move away from each other, the second spring resets, causing the roller to move out of the connecting groove. Under the elastic force of the second spring, which is still in a compressed state, the roller fits against the mesh plate. At this time, the worker controls the roller to rotate. Under the transmission action of the relative rotation of adjacent rollers, the mesh cover moves relative to the clamps and eventually falls to the storage point. The worker does not need to manually remove the mesh cover from the clamps, thus further reducing the workload of the worker. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1-7 As shown, a speaker grille forming device with a loading and unloading structure includes an operating table 1. An installation groove 2 is provided on one side surface of the operating table 1. A through groove 3 is provided through the top surface of the installation groove 2. A forming component 4 for grille forming is provided at the bottom of the installation groove 2.

[0036] A pressing component 5 for pressing is provided on one side of the upper surface of the operating table 1;

[0037] Material conveying components 6 are provided on both sides of the upper surface of the operating table 1 for conveying materials.

[0038] The molding component 4 includes several limiting rods 401. Each limiting rod 401 is fixedly installed at the bottom of the mounting groove 2. A moving ring 402 is sleeved on one side of each limiting rod 401, and a first spring 403 is sleeved on the other side of each limiting rod 401.

[0039] A molded sleeve 404 is fixedly installed on the upper surface of the moving ring 402, and the upper end of the molded sleeve 404 passes through the through groove 3;

[0040] A molding die 405 is fixedly installed at the bottom of the mounting groove 2 and between each limiting rod 401.

[0041] The pressing assembly 5 includes a support frame 501, which is fixedly installed on one side of the upper surface of the operating table 1. A cylinder 502 is fixedly installed on the upper surface of the support frame 501. The output end of the cylinder 502 passes through the support frame 501 and is fixedly installed with a pressing mold 503. A forming cavity 504 is opened on the lower surface of the pressing mold 503.

[0042] The material conveying component 6 includes an electric guide rail 601, which is fixedly installed on the corresponding side of the upper surface of the operating table 1. A vertical plate 602 is fixedly installed on the moving end of the electric guide rail 601. A clamping structure 603 for clamping the mesh plate is provided on the side of the vertical plate 602 near the forming cavity 504.

[0043] Through the above technical solution, the operator starts the cylinder 502, causing its output end to drive the pressure mold 503 to move. After the pressure mold 503 pushes against the forming sleeve 404, the first spring 403 is compressed. Under the locking action of the forming mold 405 and the forming cavity 504, the mesh plate is stretched into a mesh cover. The operator controls the clamping structure 603 to clamp both ends of the mesh plate. Then, the operator controls the electric guide rail 601, causing its moving end to drive the clamping structure 603 and the mesh plate to the upper surface of the forming sleeve 404. Then, the operator controls the clamping structure 603. After the pressure mold 503 and the forming mold 405 are in contact, the operator controls the clamping structure 603 to disengage from the mesh plate. After the mesh plate is formed into a mesh cover and moved to its original position, the operator controls the clamping structure 603 and the electric guide rail 601, so that the clamping structure 603 removes the formed mesh cover from the upper surface of the forming sleeve 404. This eliminates the need for the operator to frequently manually place and remove the mesh plate, reducing the labor intensity of the workers and improving work efficiency.

[0044] In this embodiment, the clamping structure 603 includes a sliding groove 6031, which is formed through the surface of the upright plate 602 near the molding cavity 504. Two sliders 6032 are slidably arranged in the sliding groove 6031, and a clamping plate 6033 is fixedly installed on the side of the two sliders 6032 near the molding cavity 504.

[0045] A bidirectional lead screw 6034 is rotatably installed between the two sides of the inner wall of the slide groove 6031, and two sliders 6032 are respectively threaded on both sides of the body of the bidirectional lead screw 6034.

[0046] A first motor 6035 is fixedly installed on one side of the upper surface of the upright plate 602, and the upper end of the bidirectional lead screw 6034 passes through the corresponding upright plate 602 and is fixedly connected to the output shaft end of the first motor 6035.

[0047] The staff starts the first motor 6035, which drives the bidirectional lead screw 6034 to rotate. The rotating bidirectional lead screw 6034 drives the slider 6032 to move along the slide groove 6031 by screwing in, so that the two adjacent clamping plates 6033 move and clamp the mesh plate.

[0048] It should be noted that each clamping plate 6033 has a connecting groove 7 through both sides of its upper surface, and each connecting groove 7 has a roller 8 movably installed inside it.

[0049] Each of the adjacent clamping plates 6033 has a support rod 9 fixedly installed on the side away from each other. Each of the adjacent support rods 9 has a movable frame 10 slidably installed on one side of the rod. Adjacent rollers 8 are rotatably installed on one side of the corresponding movable frame 10 through the rotating rod 801.

[0050] One end of each adjacent support rod 9 is fixedly installed with a limit plate 11;

[0051] Each support rod 9 has a second spring 12 fitted on the other side of its body.

[0052] A limiting plate 11 is fixedly installed at one end of adjacent support rods 9. By setting the limiting plate 11, the movable frame 10 is prevented from detaching from the support rod 9.

[0053] When the adjacent clamping plates 6033 move away from each other, the second spring 12 resets, causing the roller 8 to move out of the connecting groove 7. Under the elastic force of the second spring 12, which is still in a compressed state, the roller 8 fits against the mesh plate. At this time, the operator controls the roller 8 to rotate. Under the transmission action of the relative rotation of the adjacent rollers 8, the mesh cover moves relative to the clamping plate 6033 and eventually falls to the storage point. The operator does not need to manually remove the mesh cover from the clamping plate 6033, which further reduces the workload of the operator.

[0054] It is understood that in this application, each rotating rod 801 is fitted with a first pulley 13 on one side of its body, and each moving frame 10 is provided with two driving structures 14 on the side near the forming cavity 504 to drive the corresponding rotating rod 801 to rotate.

[0055] The drive structure 14 includes a fixed frame 1401, which is fixedly installed on the corresponding side of the movable frame 10. A third motor 1402 is fixedly installed on one side of the inner wall of the fixed frame 1401. A second pulley 1403 is sleeved on the output shaft of the third motor 1402. A transmission belt 1404 is sleeved on the outer wall of the second pulley 1403 and the first pulley 13.

[0056] Workers start the third motor 1402, which drives the second pulley 1403 through its output shaft. Under the transmission action of the transmission belt 1404, the first pulley 13 drives the rotating rod 801 to rotate, which in turn causes the corresponding roller 8 to rotate, so as to transport the mesh plate.

[0057] The working principle of a speaker grille forming device with a loading and unloading structure:

[0058] In operation, the operator first activates cylinder 502, causing its output end to move the pressure mold 503. After the pressure mold 503 pushes against the forming sleeve 404, the first spring 403 is compressed. Under the locking action of the forming mold 405 and the forming cavity 504, the mesh plate is stretched into a mesh cover. The operator controls the clamping structure 603 to clamp both ends of the mesh plate. Then, the operator controls the electric guide rail 601, causing its moving end to move the clamping structure 603 and the mesh plate to the upper surface of the forming sleeve 404. The operator then controls the clamping structure 603. After the pressure mold 503 and the forming mold 405 are in contact, the operator controls the clamping structure 603 to disengage from the mesh plate. After the mesh plate is formed into a mesh cover and moves to its original position, the operator controls the clamping structure 603 and the electric guide rail 601, causing the clamping structure 603 to remove the formed mesh cover from the upper surface of the forming sleeve 404. This eliminates the need for frequent manual placement and removal of the mesh plate, reducing the labor intensity of workers and improving work efficiency.

[0059] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
