Abstract

This utility model relates to the field of conveying device technology, specifically to a non-powered conveyor frame for rolling mill billets, including a milling mill discharge roller conveyor and a rolling mill feed roller conveyor. Multiple rollers are installed between the milling mill discharge roller conveyor and the rolling mill feed roller conveyor. Each roller has an anti-collision component installed at one end near the milling mill discharge roller conveyor, and the other end is rotatably connected to the rolling mill feed roller conveyor. An elastic reset component is installed inside each anti-collision component and between it and the roller. When the billet bends during conveying on the milling mill discharge roller conveyor, it first contacts the anti-collision component. The anti-collision component, in conjunction with the elastic reset component, pushes the bent portion of the billet back onto the milling mill discharge roller conveyor to prevent damage to the roller. Simultaneously, the roller-type conveyor frame has a smooth surface, a small contact area with the copper pipe, eliminates the need for nylon sheets or similar materials, provides minimal resistance, and can adapt to any height difference.

Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a non-powered conveying frame for rolling mill billets. Background Technology

[0002] The casting process produces copper tube blanks that are 22 meters long, 92 mm in outer diameter, and weigh 960 kg each. The copper oxide on the surface of the tube blanks needs to be milled off by a milling machine. The milled tube blanks are then conveyed forward by an automatic straightening and clamping wheel. After each tube blank is milled, it reaches the sensing signal, and the cylinder pushes the tube blank onto the conveyor frame of the rolling mill to be produced.

[0003] A conveyor frame is located between the milling machine and the rolling mill, pre-storing tube blanks. The height difference allows the blanks to be automatically transported to the rolling mill, ensuring the smooth operation of the production line. The existing rolling mill conveyor frames consist of 3-meter-long #10 I-beams covered with nylon sheeting, spaced 1.5 meters apart, with 10 frames per production line, capable of pre-storing 12 tube blanks. Because the height of the milling machine and the rolling mill is fixed, the height difference is not significant. Often, due to production scheduling reasons, the rolling mill production line needs to stop, and the tube blanks will press grooves into the nylon sheeting of the conveyor frame, preventing the blanks from rolling and requiring manual intervention. Secondly, the copper tube blanks are relatively soft. During the milling process, the automatically straightening clamping rollers transport the blanks, which are often too long, causing the copper tubes to bend. The front section may detach from the milling rollers and hit the conveyor frame, damaging it and requiring the replacement of the conveyor frame, increasing maintenance costs and reducing production efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a non-powered conveyor for rolling mill billets to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a non-powered conveyor frame for rolling mill billets, including a milling mill discharge roller conveyor and a rolling mill feed roller conveyor. Multiple rollers are installed between the milling mill discharge roller conveyor and the rolling mill feed roller conveyor. Each roller is equipped with an anti-collision component at one end near the milling mill discharge roller conveyor, and the other end is rotatably connected to the rolling mill feed roller conveyor. An elastic reset component is installed inside each anti-collision component and between it and the roller, and each anti-collision component is slidably connected to the milling mill discharge roller conveyor.

[0006] When the tube blank bends during the conveying process of the milling machine's discharge roller conveyor, it will first come into contact with the anti-collision component. The anti-collision component, together with the elastic reset component, will push the bent part of the tube blank back onto the milling machine's discharge roller conveyor to prevent damage to the rollers.

[0007] Preferably, the anti-collision component includes:

[0008] A sleeve is fitted onto the end of the roller away from the mill feed roller table, and the elastic reset member is disposed inside the sleeve;

[0010] The anti-collision plate has one end fixedly connected to the end of the guide plate near the conveying direction of the milling machine's discharge roller, and the other end is inclined along the direction of the roller.

[0011] Preferably, the outer surface of the sleeve is provided with a conical surface that is inclined downward along the direction of the roller.

[0015] A slot is provided at the end of the roller away from the mill feed roller table;

[0017] A spring is sleeved on the guide rod, with its two ends abutting against the sleeve and the roller, respectively.

[0018] The beneficial effects of this utility model are as follows: When the tube blank bends during the conveying process of the milling machine's discharge roller conveyor, it will first come into contact with the anti-collision component. The anti-collision component, together with the elastic reset component, will push the bent part of the tube blank back onto the milling machine's discharge roller conveyor to prevent damage to the roller. At the same time, the roller-type conveyor frame has a smooth surface and a small contact area with the copper tube, so there is no need to lay nylon plates or the like, and there is not much resistance.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0028] like Figures 1 to 4As shown, a non-powered conveyor frame for rolling mill billets includes a milling mill discharge roller conveyor and a rolling mill feed roller conveyor. Multiple rollers are installed between the milling mill discharge roller conveyor and the rolling mill feed roller conveyor. Each roller has an anti-collision component installed at one end near the milling mill discharge roller conveyor, and the other end is rotatably connected to the rolling mill feed roller conveyor. Each anti-collision component has an elastic reset element installed between its interior and the roller, and each anti-collision component is slidably connected to the milling mill discharge roller conveyor.

[0029] When the tube blank bends during the conveying process of the milling machine's discharge roller conveyor, it will first come into contact with the anti-collision component. The anti-collision component, together with the elastic reset component, will push the bent part of the tube blank back onto the milling machine's discharge roller conveyor to prevent damage to the rollers.

[0030] As an optional implementation, the anti-collision component includes:

[0031] A sleeve is fitted onto the end of the roller away from the mill feed roller table, and the elastic reset member is disposed inside the sleeve;

[0032] A guide plate is fixedly disposed at the end of the sleeve away from the roller, and the bottom of the guide plate is slidably connected to the discharge roller conveyor of the milling machine;

[0033] The anti-collision plate has one end fixedly connected to the end of the guide plate near the conveying direction of the milling machine's discharge roller, and the other end is inclined along the direction of the roller.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the billet bends during the conveying process of the milling machine's discharge roller conveyor, it will first contact the anti-collision plate. The billet moves to the guide plate according to the tilt angle of the anti-collision plate. At the same time, it will generate a thrust on the anti-collision plate, causing the anti-collision plate to drive the guide plate to move towards the roller. The guide plate drives the sleeve to move. When the billet moves to the guide plate, the elastic reset component works to generate a reset resistance force on the sleeve, causing the sleeve to reset. The sleeve drives the guide plate to reset, and the guide plate pushes the billet to move onto the milling machine's discharge roller conveyor to complete the anti-collision and guiding work.

[0035] As an optional implementation, the outer surface of the sleeve is provided with a tapered surface that is inclined downward along the direction of the roller.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the outer wall of the sleeve is a conical surface. When the billet is transferred from the milling machine to the drum on the discharge roller table, the billet is first transferred to the sleeve. After passing through the conical surface on the sleeve, it automatically rolls onto the drum and the mill feed roller table under the action of gravity.

[0037] As an optional implementation, a fixed plate is fixedly provided at the bottom of the milling machine's discharge roller conveyor, a first limiting plate is fixedly provided at the bottom of the fixed plate, a sliding plate is provided at the bottom of the first limiting plate, an extension plate is fixedly provided at one end of the sliding plate in a vertical state, the free end of the extension plate is fixedly connected to the bottom of the guide plate, a sliding groove is provided through the middle of the sliding plate, a connecting plate is provided inside the sliding groove, one end of the connecting plate is fixedly connected to the first limiting plate, a second limiting plate is provided at the bottom of the sliding plate, and the top of the second limiting plate is fixedly connected to the free end of the connecting plate.

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, when the guide plate moves towards the roller, it will drive the extension plate to move. The extension plate will drive the slide plate to move on the connecting plate. The slide plate is restricted by the first limit plate and the second limit plate and cannot fall off, thus playing a supporting role, thereby realizing the sliding connection between the guide plate and the milling machine discharge roller.

[0039] As an optional implementation, a plurality of pulleys are respectively attached to the side of the first limiting plate, and the axle of each pulley is rotatably connected to the slide plate.

[0040] like Figure 2 , Figure 3 and Figure 4 As shown, by setting multiple pulleys on the skateboard and attaching them to the first limiting plate, the sliding efficiency of the skateboard is improved and the problem of jamming is avoided.

[0041] As an optional implementation, the resilient reset element includes:

[0042] A slot is provided at the end of the roller away from the mill feed roller table;

[0043] A guide rod is disposed in the slot, and one end of the guide rod is fixedly connected to the end of the sleeve near the guide plate.

[0044] A spring is sleeved on the guide rod, with its two ends abutting against the sleeve and the roller, respectively.

[0045] like Figure 3 As shown, the spring abuts against the sleeve and the roller to complete the reset of the sleeve.

[0046] The working principle is as follows: When the tube blank bends during the conveying process of the milling machine's discharge roller conveyor, it will first come into contact with the anti-collision component. The anti-collision component, together with the elastic reset component, will push the bent part of the tube blank back onto the milling machine's discharge roller conveyor to prevent damage to the rollers. At the same time, the roller-type conveyor frame has a smooth surface and a small contact area with the copper tube, so there is no need to lay nylon plates or the like, and there is not much resistance. It can adapt to any height difference.

[0047] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of this utility model is limited to these examples; within the framework of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this utility model as described above, which are not provided in the details for the sake of brevity. Any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
