Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, specifically a feeding structure for a press. Background Technology

[0002] As core equipment in metal processing, automobile manufacturing, and electronic component production, the feeding structure of a press is a crucial element for achieving efficient, safe, and automated production. With the increasing demands for precision, efficiency, and safety in the manufacturing industry, the design and optimization of feeding structures have become an important direction for industrial technology development. The evolution of press feeding structures is essentially a microcosm of the manufacturing industry's transformation from "extensive" to "lean" and "intelligent" production. This evolution reflects both the efficiency and safety challenges of traditional production models and the urgent needs of the industrial era for automation, flexibility, and sustainable development. In the future, with the integration of collaborative robots, 5G communication, and edge computing technologies, feeding structures will further evolve towards "cognitive intelligence," becoming one of the core units of smart factories.

[0003] When using the feeding structure of a press to transfer oil and filter, traditional press feeding equipment usually uses a conveyor belt for auxiliary feeding. Because the materials are close together, uneven feeding may occur during feeding, which may cause the press to jam when pressing the oil and filter, or cause empty material to be fed due to feeding jam, thus reducing the working efficiency of the equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a feeding structure for a press, which solves the problem that traditional press feeding equipment generally uses a conveyor belt for auxiliary feeding. This can easily lead to uneven feeding due to the close proximity of materials, causing material jamming when the press presses the oil filter, or empty material being fed due to feeding jamming, thus reducing the working efficiency of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding structure for a press, comprising a main body, a first L-shaped fixed platform fixedly connected to the top left end of the main body, a pressure device fixedly mounted on the top of the first L-shaped fixed platform, and the output end of the pressure device extending out of the inner top surface of the first L-shaped fixed platform; a second L-shaped fixed platform fixedly connected to the top right end of the main body, a feeding slide rail provided at the top center of the second L-shaped fixed platform, a feeding slide tube fixedly mounted on one side of the feeding slide rail, and the feeding slide tube communicating with the feeding slide rail, and a clamping groove provided at the bottom end of the feeding slide tube.

[0006] In a preferred embodiment, a motor is fixedly installed on one side of the inner bottom surface of the main body of the device, and a transmission turntable is fixedly welded to the output end of the motor through a fixed short rod. A first transmission short rod is fixedly installed on the outer surface of the transmission turntable.

[0007] In a preferred embodiment, a fixing plate is fixedly connected to the inner wall of one side of the device body, and a rotating rod is rotatably connected to the end of the fixing plate near the motor. The top end of the rotating rod extends out of the top of the device body and is rotatably set with the device body.

[0008] In a preferred embodiment, an intermittent transmission wheel is fixedly sleeved on the rotating rod, and the intermittent transmission wheel is respectively matched with the arc groove of the transmission turntable and the first transmission short rod.

[0009] In a preferred embodiment, a rotating disk is fixedly connected to the top of the rotating rod, and four second transmission rods are equidistantly arranged on the outer surface of the rotating disk along the circumferential direction. Each of the four second transmission rods has a transmission roller rotatably mounted on its top.

[0010] In a preferred embodiment, a limiting slide rod is slidably provided inside the second L-shaped fixing platform, and two limiting blocks are arranged opposite each other on the outer surface of the limiting slide rod. A clamping block is fixedly provided at one end of the limiting slide rod, and an anti-slip pad is fixedly provided in the groove of the clamping block.

[0011] In a preferred embodiment, a return spring is sleeved on the outer surface of the limiting slide rod, and one end of the return spring is fixedly welded to the feeding slide tube, and the other end is fixedly welded to the clamping block. An inclined transmission block is fixedly provided on one side of the bottom of the clamping block, and the inclined transmission block is engaged with the transmission roller.

[0012] Beneficial effects

[0013] This invention provides a feeding structure for a press. Compared with the prior art, it has the following advantages:

[0014] In this invention, starting the motor can drive the transmission turntable to rotate and output, thereby driving the first transmission short rod to rotate circumferentially along the transmission turntable. Through the intermittent rotation setting of the first transmission short rod and the intermittent transmission wheel, the rotating rod can drive the rotating disc to rotate synchronously and intermittently, and each rotation angle is 90°. This ensures that the four grooves opened on the rotating disc will correspond to the bottom end of the feeding slide and the output end of the pressure device in turn each time the disc rotates intermittently, which facilitates the subsequent material unloading and pressing of the device.

[0015] By engaging the transmission rollers with the inclined transmission block, when the transmission rollers and the second transmission rod stop intermittently rotating around the rotating disk, the force generated by the transmission rollers drives the inclined transmission block and the clamping block to slide forward. This causes the clamping block to disengage and hold the material, allowing the material to fall into the groove of the feeding slide corresponding to the rotating disk. Subsequent materials continue to slide down into the feeding slide, stopping after contacting the top of the previous material. When the transmission rollers resume intermittent rotation, they disengage from the inclined transmission block, causing the inclined transmission block to lose the force of the transmission rollers. The return spring then resets the clamping block, facilitating subsequent material feeding and achieving uniform material feeding while preventing jamming. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figure 1-3 A feeding structure for a press includes a main body 1. A first L-shaped fixed platform 2 is fixedly connected to the top left end of the main body 1. A pressure device 3 is fixedly installed on the top of the first L-shaped fixed platform 2, and the output end of the pressure device 3 extends out of the inner top surface of the first L-shaped fixed platform 2. A second L-shaped fixed platform 4 is fixedly connected to the top right end of the main body 1. A feeding slide 5 is provided at the top center of the second L-shaped fixed platform 4. A feeding slide tube 6 is fixedly installed on one side of the feeding slide 5 and is connected to the feeding slide 5. A clamping groove 7 is provided at the bottom end of the feeding slide tube 6.

[0025] The first L-shaped fixed platform 2 provides stability for the pressing when the pressure device 3 outputs. The second L-shaped fixed platform 4 can connect and fix the feeding slide tube 6 to ensure its stability. The material can slide continuously into the feeding slide tube 6 through the feeding slide 5 and fall steadily into the corresponding grooves on the rotating disc 14. The clamping groove 7 can cooperate with the clamping block 18 to clamp the material inside the feeding slide tube 6.

[0026] A motor 8 is fixedly installed on the bottom surface of the device body 1 near one side. A transmission turntable 9 is fixedly welded to the output end of the motor 8 via a fixed short rod. A first transmission short rod 10 is fixedly installed on the outer surface of the transmission turntable 9. A fixed plate 11 is fixedly connected to the inner wall of one side of the device body 1. A rotating rod 12 is rotatably connected to the end of the fixed plate 11 near the motor 8. The top end of the rotating rod 12 extends out of the top of the device body 1 and is rotatably set with the device body 1. An intermittent transmission wheel 13 is fixedly sleeved on the rotating rod 12. The intermittent transmission wheel 13 is respectively matched with the arc groove of the transmission turntable 9 and the first transmission short rod 10. A rotating disk 14 is fixedly connected to the top end of the rotating rod 12. Four second transmission short rods 15 are equidistantly arranged along the circumferential direction on the outer surface of the rotating disk 14. A transmission roller 16 is rotatably set at the top end of each of the four second transmission short rods 15.

[0027] The output shaft of motor 8 drives the transmission turntable 9 to rotate. The rotation of the transmission turntable 9 drives the first transmission short rod 10 to rotate circumferentially along the transmission turntable 9. The fixed plate 11 provides stability when the rotating rod 12 rotates. The rotation rod 12 and the intermittent transmission wheel 13 are matched with the arc groove of the transmission turntable 9 and the first transmission short rod 10 respectively. When the first transmission short rod 10 rotates circumferentially along the transmission turntable 9, it drives the intermittent transmission wheel 13 and the rotating rod 12 to rotate intermittently synchronously. The rotation of the rotating rod 12 drives the rotating disc 14 to rotate intermittently synchronously. Each rotation angle is 90°, so that the four grooves on the rotating disc 14 will correspond to the bottom end of the feeding slide 6 and the output end of the pressure device 3 in turn when rotating circumferentially, which facilitates material dropping and pressing. The intermittent rotation of the rotating disc 14 drives the second transmission short rod 15 and the transmission roller 16 to rotate intermittently circumferentially synchronously.

[0028] Example 2:

[0029] Please see Figure 1-5 This embodiment provides a technical solution based on embodiment one: a limiting slide rod 17 is slidably provided inside the second L-shaped fixed platform 4, and two limiting blocks are provided opposite to each other on the outer surface of the limiting slide rod 17. A clamping block 18 is fixedly provided at the rear end of the limiting slide rod 17, and an anti-slip pad is fixedly provided in the groove of the clamping block 18. A return spring 19 is sleeved on the outer surface of the limiting slide rod 17, and one end of the return spring 19 is fixedly welded to the second L-shaped fixed platform 4, and the other end is fixedly welded to the clamping block 18. An inclined transmission block 20 is fixedly provided at the bottom of the clamping block 18 near the front edge, and the inclined transmission block 20 is in transmission engagement with the transmission roller 16.

[0030] When the transmission roller 16 contacts the inclined transmission block 20, the rotation of the transmission roller 16 can more quickly generate a pushing force on the inclined transmission block 20. The generated force will cause the clamping block 18 and the limiting slide rod 17 to retract backward, and drive the return spring 19 to retract. The two limiting blocks arranged opposite to each other on the surface of the limiting slide rod 17 can ensure that the limiting slide rod 17 will not rotate during the sliding process, so that the clamping block 18 disengages from the clamping groove 7 opened in the feeding slide tube 6, allowing the material inside the feeding slide tube 6 to flow out of the feeding slide tube 6. The material falls into one of the grooves on the rotating disk 14. The subsequent material slides into the upper material tube 6 through the feeding slide 8. When the rotating disk 14 drives the second transmission rod 15 and the transmission roller 16 to rotate synchronously and intermittently, the transmission roller 16 disengages from the inclined transmission block 20 and is quickly extended and reset by the return spring 19. This causes the limit slide rod 17 and the clamping block 18 to extend and reset forward, thus completing a new clamping of the material. This cycle repeats, continuously feeding material into the groove of the rotating disk 14.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] During operation, the program is set via PLC. First, the motor 8 is started, and the output shaft of the motor 8 drives the transmission turntable 9 to rotate. The rotation of the transmission turntable 9 drives the first transmission rod 10 to rotate circumferentially along the transmission turntable 9. Through the setting of the rotating rod 12 and the intermittent transmission wheel 13, and the intermittent transmission wheel 13 engaging with the arc groove of the transmission turntable 9 and the first transmission rod 10 respectively, when the first transmission rod 10 rotates circumferentially along the transmission turntable 9, it drives the intermittent transmission wheel 13 and the rotating rod 12 to rotate intermittently synchronously. The rotation of the rotating rod 12 drives the rotating disc 14 to rotate intermittently synchronously. Each rotation angle is 90°, so that the four grooves on the rotating disc 14 will alternately correspond to the bottom end of the feeding slide 6 and the output end of the pressure device 3 each time they rotate circumferentially, which facilitates material dropping and pressing. The intermittent rotation of the rotating disc 14 drives the second transmission rod 15 and the transmission roller 16 to rotate intermittently circumferentially synchronously.

[0033] When the transmission roller 16 contacts the inclined transmission block 20, the resulting force causes the clamping block 18 and the limiting slide rod 17 to slide forward, and drives the return spring 19 to retract inward. This causes the clamping block 18 to disengage from the clamping groove 7 of the feeding slide tube 6, allowing the material inside the feeding slide tube 6 to fall into one of the grooves on the rotating disk 14. Subsequent materials slide continuously into the feeding slide tube 6 through the feeding slide 8. When the rotating disk 14 drives the second transmission rod 15 and the transmission roller 16 to rotate synchronously and intermittently, the transmission roller 16 disengages from the inclined transmission block 20. The reverse force of the retracting return spring 19 can drive the limiting slide rod 17 and the clamping block 18 to slide back to their original positions. This allows the anti-slip pads fixed in the groove of the clamping block 18 to hold the subsequent materials, facilitating continuous feeding into the groove of the rotating disk 14. This avoids uneven feeding and empty feeding on the transmission equipment, improving the working efficiency of the equipment.
