Description

Technical Field

[0001] This utility model relates to the field of steel ball storage technology, specifically to a steel ball placement rack. Background Technology

[0002] In the production, processing, and storage of steel balls, steel ball racks are commonly used auxiliary equipment for the temporary storage of finished steel balls to facilitate subsequent orderly unloading operations.

[0003] In existing technology, steel balls are directly placed into a placement rack after production, and stored by interception with the help of a stop plate. When discharge is required, the stop plate is pulled up, and the steel balls can roll along the inclined surface of the placement rack and be discharged through the discharge cylinder. However, there are obvious shortcomings in practical applications: because the inclined surface of the placement rack is inclined, the steel balls will impact the stop plate during the rolling process. Long-term impact can easily cause the stop plate to deform, affecting the stability of the interception and discharge functions. Utility Model Content

[0004] To solve the above-mentioned technical problems, a steel ball placement rack is provided, which solves the problems existing in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a steel ball placement rack, which consists of an inclined frame, a discharge cylinder fixedly connected to the lower inclined end of the frame, and an interception plate slidably inserted into the lower inclined end of the frame. It also includes a steel ball deceleration mechanism for reducing the rolling speed of the steel balls on the frame. A storage groove is provided on the inner wall of the bottom end of the frame, and the steel ball deceleration mechanism is located in the storage groove.

[0006] The steel ball deceleration mechanism includes a rubber belt movable within the storage groove and a transmission mechanism for movably loading the rubber belt, wherein the top surface of the rubber belt is horizontal to the inner wall of the bottom end of the frame.

[0007] Preferably, the transmission mechanism includes two mounting plates symmetrically fixed to both sides of the bottom surface of the frame, two rotating rollers symmetrically rotatably connected between the two mounting plates, a transmission belt drivingly connecting the two rotating rollers, and a rubber belt fitted over the transmission belt.

[0008] Preferably, a motor is mounted on the side wall of one of the mounting plates, and the drive shaft of the motor passes through the mounting plate and is fixedly connected to the end of one of the rollers.

[0009] Preferably, the surface of the transmission belt is fixedly embedded with a hook and loop fastener, and both ends of the rubber belt are fixedly embedded with hook and loop fastener loops that are adhered to the hook and loop fastener fastener.

[0010] Preferably, a liftable pressing roller is provided above one end of the rubber belt, and two limiting rollers are symmetrically arranged above the middle of the rubber belt, with the limiting rollers rotating laterally between the inner walls on both sides of the frame.

[0011] Preferably, both ends of the pressing roller are rotatably connected to connecting blocks, the inner sidewall of the frame is provided with a sliding groove that cooperates with the connecting block, and a transmission screw that is rotatably connected to the inner wall of the bottom end of the sliding groove is threaded through the inner wall of the connecting block.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] (1) By setting the rubber belt, when the steel ball rolls over the frame, the rubber belt reduces the rolling speed of the steel ball through surface friction resistance, thereby reducing the impact of the steel ball on the interceptor plate.

[0014] (2) By setting up the transmission mechanism, the transmission belt is driven to run, thereby synchronously driving the rubber belt to run, quickly switching the surface of the rubber belt and the inner wall of the bottom of the frame to be horizontal, adjusting the friction contact part between the rubber belt and the steel ball, avoiding excessive local wear, and extending its service life.

[0015] (3) By setting up the pressure roller and two limiting rollers, when laying the rubber belt to the transmission belt, one end of the rubber belt can be passed between the limiting rollers first, and the hook and loop fastener of the end can be bonded to the hook and loop fastener. The limiting roller can be rotated to guide it to smoothly enter the laying position, and then the pressure roller can be lowered to press the top surface of the end, and the hook and loop fastener can be used to form a stable starting fixed point to prevent displacement. At the same time, the tension of the rubber belt can be controlled by the lifting height of the pressure roller and the rotation resistance of the limiting roller, so that it is evenly attached to the surface of the transmission belt and avoids wrinkles or looseness.

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] Reference Figure 1-3 As shown, a steel ball placement rack consists of an inclined frame 1, a discharge cylinder 2 fixedly connected to the lower inclined end of the frame 1, and an interception plate 3 slidably inserted into the lower inclined end of the frame 1.

[0023] With the frame 1, discharge cylinder 2 and interceptor plate 3, when the steel ball is put into the frame 1, the inclined frame 1 can guide the steel ball to roll downwards. The interceptor plate 3 can intercept and store the rolling steel ball. When it is necessary to discharge, the interceptor plate 3 can be slid out and the steel ball can roll down the frame 1 to the discharge cylinder 2 for discharge.

[0024] However, in actual applications, due to the inclined surface of frame 1, the steel ball will impact the interception plate 3 during rolling. Long-term impact can easily cause the interception plate 3 to deform, affecting the stability of the interception and discharge functions.

[0025] Therefore, referring to Figure 2 As shown, it is worth noting that it also includes a steel ball deceleration mechanism for reducing the rolling speed of the steel ball on the frame 1. The bottom inner wall of the frame 1 is provided with a receiving groove 4, and the steel ball deceleration mechanism is located in the receiving groove 4.

[0026] The steel ball deceleration mechanism includes a rubber belt 8 that can be moved within the storage groove 4, with the top surface of the rubber belt 8 being horizontal to the bottom inner wall of the frame 1.

[0027] By setting the rubber belt 8, when the steel ball rolls over the frame 1, the rubber belt 8 reduces the rolling speed of the steel ball through surface friction resistance, thereby reducing the impact of the steel ball on the interceptor plate 3.

[0028] Furthermore, referring to Figure 2 As shown, it is worth noting that the steel ball deceleration mechanism also includes a transmission mechanism for the movable loading rubber belt 8;

[0029] The transmission mechanism includes two mounting plates 5 symmetrically fixed on both sides of the bottom surface of the frame 1. Two rotating rollers 6 are symmetrically rotatably connected between the two mounting plates 5. A transmission belt 7 is connected between the two rotating rollers 6. A rubber belt 8 is fitted on the outside of the transmission belt 7.

[0030] A motor is mounted on the side wall of one of the mounting plates 5, and the drive shaft of the motor passes through the mounting plate 5 and is fixedly connected to the end of one of the rotating rollers 6.

[0031] By setting up a transmission mechanism, the motor is turned on, which drives one of the mounting plates 5 to rotate, thereby driving the transmission belt 7 to rotate, and synchronously driving the rubber belt 8 to rotate. This allows the surface of the rubber belt 8 to be level with the inner wall of the bottom of the frame 1, adjusting the friction contact between the rubber belt 8 and the steel ball, avoiding excessive local wear, and extending its service life.

[0032] Furthermore, referring to Figure 2 and Figure 3 As shown, it is worth noting that the surface of the transmission belt 7 is fixedly embedded with a hook and loop fastener 9, and both ends of the rubber belt 8 are fixedly embedded with hook and loop fastener rough surfaces 10 that are adhered to the hook and loop fastener 9.

[0033] With the hook and loop fastener 10 and hook and loop fastener 9, the rubber belt 8 can be attached to the hook and loop fastener 9 on the surface of the transmission belt 7 by the hook and loop fastener 10, and move synchronously with the transmission belt 7. It is easy to disassemble and replace, and can be quickly peeled off and replaced when it is severely worn.

[0034] Furthermore, referring to Figure 2 As shown, it is worth noting that a lifting and lowering pressure roller 12 is provided above one end of the rubber belt 8, and two limiting rollers 11 are symmetrically arranged above the middle of the rubber belt 8. The limiting rollers 11 rotate laterally between the inner walls on both sides of the frame 1.

[0035] With the setting of the pressure roller 12 and two limiting rollers 11, when laying the rubber belt 8 onto the transmission belt 7, one end of the rubber belt 8 can be passed between the limiting rollers 11 first, and the hook and loop fastener 10 of that end can be bonded to the hook and loop fastener 9. The limiting roller 11 can be rotated to guide it to smoothly enter the laying position, and then the pressure roller 12 can be lowered to press the top surface of that end, forming a stable starting fixed point with the hook and loop fastener to prevent displacement. At the same time, the tension of the rubber belt 8 can be controlled by the lifting height of the pressure roller 12 and the rotation resistance of the limiting roller 11, so that it is evenly attached to the surface of the transmission belt 7 and avoids wrinkles or looseness.

[0036] Furthermore, referring to Figure 2 As shown, it is worth noting that both ends of the pressing roller 12 are rotatably connected to connecting blocks (not shown in the figure), and the inner side wall of the frame 1 is provided with a sliding groove that cooperates with the connecting block. The inner wall of the connecting block is threaded with a transmission screw 13 that is rotatably connected to the inner wall of the bottom end of the sliding groove.

[0037] Rotating the transmission screw 13 drives the connecting block to move linearly along the slide groove through the threaded transmission, thereby driving the pressing roller 12 to achieve precise lifting and lowering adjustment. The pressing force of the pressing roller 12 on the rubber belt 8 can be precisely controlled according to the thickness of the rubber belt 8 and the laying requirements.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
