Description

Technical Field

[0001] This application relates to the field of metal processing technology, and in particular to an automatic feeding device for T-shaped products with high stability. Background Technology

[0002] A bolt consists of a head and a shank, and needs to be used with a nut to fasten two parts with through holes. It is a type of T-shaped product with a wide range of applications, covering fields such as engineering construction and machinery manufacturing. Market demand is growing, and the production process of bolts is also gradually improving. In the process of mass production of bolts, the efficiency of loading and unloading can be greatly improved by the feeding device, thereby improving production efficiency.

[0003] Among the existing bolt feeding devices, there is a bolt processing fast feeding device such as the one with announcement number CN221874114U. It uses a servo motor to drive the threaded rod to rotate, and the screw ring drives two movable plates to move to the left. The movable plates push the rotating shaft through two linkage rods, and the rotating shaft pushes the left end of the hopper to rise through two fixed plates. Then, the operator removes the baffle from the discharge port, and the raw material inside the hopper is discharged from the discharge port by its own gravity. The whole device can realize the automatic unloading operation of bolt raw materials.

[0004] However, in practical applications, the opening and closing range of the baffle is difficult to control. During the unloading process, the material may accumulate at the discharge port when the baffle is closed, resulting in incomplete closure and making it difficult to meet the requirements for accurate unloading. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a highly stable automatic feeding device for T-shaped products, so as to provide stable and accurate feeding.

[0006] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0007] A highly stable automatic feeding device for T-shaped products includes a frame, with four casters mounted on the bottom of the frame, a placement box hinged to the top of the frame, an upper sliding door snapped into the side opening of the placement box, the bottom surface of the upper sliding door being inclined, a sliding sleeve connected to the outer side of the upper sliding door, a connecting rod slidably connected inside the sliding sleeve, and a lower sliding door fixedly connected to the bottom of the connecting rod.

[0008] A transmission mechanism is provided on the outer side of the frame. The transmission mechanism includes a mounting base, a gear, a rack, and a worm. The mounting base is fixedly connected to the side wall of the placement box. The gear is rotatably connected to the mounting base. The rack includes two racks, which are respectively connected to the sides of the upper sliding door and the lower sliding door. The worm is rotatably connected to the side of the mounting base. The worm establishes a transmission relationship with the gear, and both racks establish a transmission relationship with the gear.

[0009] A weight sensor is fixedly connected to the bottom of the placement box, and a horizontal plate is installed above the weight sensor.

[0010] Preferably, the upper sliding door includes connecting strips at both ends, and the upper sliding door is snapped onto the outside of the placement box by the connecting strips.

[0011] Preferably, a limiting block is connected to the top of the upper sliding door, and the limiting block is located directly above the side wall of the placement box.

[0012] Preferably, the height of the connecting strip is the same as the height of the placement box, and the connecting strip has a groove on one side wall facing the placement box;

[0013] The side wall of the placement box is connected to a limiting strip, and the connecting strip is snapped onto the outside of the limiting strip.

[0014] Preferably, the sliding door is fitted to the side of the connecting strip.

[0015] Preferably, the lower sliding door is fitted to the outer wall of the upper sliding door.

[0016] Preferably, a slide rail is connected to the middle of the frame, a lead screw is inserted inside the slide rail, a slider is sleeved on the outside of the lead screw, and a motor is fixedly connected to the end of the slide rail, and the motor establishes a transmission relationship with the lead screw;

[0017] A piston is connected to the side wall of the slider, and a sleeve is fitted on the outside of the piston;

[0018] A hydraulic cylinder is hinged to the lower middle part of the frame, and the other end of the hydraulic cylinder is hinged to the bottom of the placement box. A connecting oil circuit is established between the hydraulic cylinder and the sleeve.

[0019] Compared with the prior art, this application has at least the following advantages:

[0020] In the above scheme, by setting up an upper sliding door, a lower sliding door, gears, racks and worm gears, when the feeding is completed, the material stops flowing towards the outlet side of the placement box due to the compression of the lower sliding door as it moves upward. As the upper sliding door moves downward, it presses the material into the placement box through its inclined surface, thereby reducing the material obstruction between the upper and lower sliding doors and ensuring that the upper and lower sliding doors can close smoothly, thus facilitating the control of the material conveying volume.

[0021] In the above solution, by setting up slide rails, sliders, lead screws, pistons, sleeves and oil cylinders, and using hydraulic drive, the placement box is lifted by the oil cylinder to facilitate the rapid outflow of raw materials in the placement box, saving time and improving efficiency.

Detailed Implementation

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4The present application provides an embodiment of a highly stable automatic feeding device for T-shaped products, which includes a frame 1. The frame 1 has four feet at the bottom equipped with casters 101. The top of the frame 1 is hinged to a placement box 2. The side opening of the placement box 2 is snapped with an upper sliding door 201. The bottom surface of the upper sliding door 201 is inclined. The outer side of the upper sliding door 201 is connected to a sliding sleeve 202. The inner side of the sliding sleeve 202 is slidably connected to a connecting rod 203. The bottom of the connecting rod 203 is fixedly connected to a lower sliding door 3.

[0033] A transmission mechanism is provided on the outside of the frame 1. The transmission mechanism includes: a mounting base 401, a gear 402, a rack 403, and a worm 404. The mounting base 401 is fixedly connected to the side wall of the placement box 2. The gear 402 is rotatably connected to the mounting base 401. The rack 403 includes two racks, which are respectively connected to the sides of the upper sliding door 201 and the lower sliding door 3. The worm 404 is rotatably connected to the side of the mounting base 401. The worm 404 establishes a transmission relationship with the gear 402. Both racks 403 establish a transmission relationship with the gear 402.

[0034] A weight sensor 5 is fixedly connected to the bottom of the inner side of the placement box 2, and a horizontal plate 501 is set above the weight sensor 5.

[0035] In use, by moving the entire device below the discharge port of the upstream equipment, the placement box 2 can collect the raw materials of the upstream equipment. As the raw materials in the placement box 2 continue to increase, the total amount of raw materials is measured by the weight sensor 5. After reaching the predetermined value, the device is moved to the feed port position of the downstream equipment by the fuma wheel 101. By rotating the worm gear 404, the gear 402 rotates, which in turn drives the two racks 403 to move, causing the upper sliding door 20101 to move upward and the lower sliding door 3 to move downward, creating a gap between the upper sliding door 20101 and the lower sliding door 3 for the raw materials to flow out.

[0036] When the sliding door 3 moves to the bottom of the placement box 2, the raw material can be poured out from the placement box 2, thereby reducing the value measured by the weight sensor 5, which is used to determine the amount of raw material conveyed.

[0037] Conversely, when feeding is complete, the worm gear 404 is rotated in the opposite direction, and the material is squeezed by the lower sliding door 3 and stops flowing towards the outlet side of the placement box 2. As the upper sliding door 201 moves downward, the bottom surface of the upper sliding door 201 is inclined, and the upper sliding door 201 presses the material into the placement box 2 through the inclined surface, thereby reducing the material obstruction between the upper sliding door 201 and the lower sliding door 3, thus ensuring that the upper sliding door 201 and the lower sliding door 3 can close smoothly, thereby facilitating the control of the material conveying amount.

[0038] In this embodiment, as Figures 2-7As shown, the upper sliding door 201 includes connecting strips 204 at both ends, and the upper sliding door 201 is snapped onto the outside of the placement box 2 by the connecting strips 204;

[0039] The upper sliding door 201 is limited by the connecting strip 204 and the placement box 2, so the upper sliding door 201 cannot move relative to the width direction of the placement box 2, thus maintaining the stability of the position of the upper sliding door 201. At the same time, it ensures that the rack 403 and gear 402 on the side of the upper sliding door 201 are stably meshed, so that the upper sliding door 201 maintains a stable and smooth state when it is opened.

[0040] The top of the upper sliding door 201 is connected to a limiting block 205, which is located directly above the side wall of the placement box 2.

[0041] Limiting block 2 is used to prevent the upper sliding door 201 from going too far down and can limit the position of the upper sliding door 201.

[0042] The height of the connecting strip 204 is the same as the height of the placement box 2, and the connecting strip 204 has a groove on one side wall facing the placement box 2;

[0043] The side wall of the placement box 2 is connected to a limiting strip 206, and the connecting strip 204 is snapped onto the outside of the limiting strip 206;

[0044] During the up-and-down movement of the upper sliding door 201, the connecting strip 204 remains engaged with the placement box 2 to ensure the accurate positioning of the upper sliding door 201;

[0045] The cooperation between the limiting strip 206 and the connecting strip 204 is used to limit the displacement of the upper sliding door 201 relative to the length direction of the placement box 2, thereby further improving the stability of the upper sliding door 201.

[0046] The sliding door 3 is fitted to the side of the connecting strip 204;

[0047] The lower sliding door 3 engages with the connecting strip 204, so that even when there is a gap between the upper sliding door 201 and the lower sliding door 3, the lower sliding door 3 still maintains a stable position relative to the upper sliding door 201, which is conducive to subsequent closing.

[0048] The lower sliding door 3 is fitted to the outer wall of the upper sliding door 201;

[0049] The lower sliding door 3 and the upper sliding door 201 fit tightly together, reducing gaps and thus effectively controlling the leakage of raw materials.

[0050] A slide rail 102 is connected to the middle of the frame 1. A lead screw 103 is inserted inside the slide rail 102. A slider 104 is sleeved on the outside of the lead screw 103. A motor 105 is fixedly connected to the end of the slide rail 102. The motor 105 and the lead screw 103 establish a transmission relationship.

[0051] A piston 106 is connected to the side wall of the slider 104, and a sleeve 107 is fitted on the outside of the piston 106.

[0052] A hydraulic cylinder 6 is hinged to the lower middle part of the frame 1, and the other end of the hydraulic cylinder 6 is hinged to the bottom of the placement box 2. A connecting oil circuit is established between the hydraulic cylinder 6 and the sleeve 107.

[0053] When it is necessary to quickly remove the raw materials from the placement box 2, the motor 105 drives the lead screw 103 to rotate. The slider 104 moves relative to the lead screw 103 under the limitation of the slide rail 102. The linear motion of the slider 104 is converted into the linear motion of the piston 106 on the sleeve 107. Hydraulic oil is injected into the sleeve 107. The piston 106 presses the hydraulic oil in the sleeve 107 into the oil cylinder 6, causing the oil cylinder 6 to extend and drive the placement box 2 to swing. The opening side of the placement box 2 is hinged to the frame 1 through a rotating shaft, thereby tilting the placement box 2. The raw materials flow along the inclined surface of the horizontal plate 501 under the action of their own gravity, thereby achieving the effect of accelerating the outflow speed of the raw materials.

[0054] The motor 105 is equipped with a matching power supply and controller to facilitate intelligent control.
