Description

Technical Field

[0001] The invention relates to the field of powder forming equipment, in particular to an automatic breaking and length-fixing device for an anti-drop connecting rod. Background Art

[0002] In the coal, metallurgy, chemical, building materials and briquette industries, some materials need to go through a powder forming process, that is, bulk materials are formed by roller extrusion, and rod-shaped objects are squeezed out from the extrusion equipment. The rod-shaped object is tilted and extruded from between two rollers at a certain angle; when the rod reaches a certain length, due to the effect of gravity, when the gravity is greater than the internal binding force of the extruded rod, the rod will break, and the broken rod will fall from a higher position. In the process of falling, it is easy to break and cause secondary breakage, resulting in inconsistent length of the rod, affecting the use effect. Contents of the invention

[0003] In order to solve this problem, the present invention provides an automatic breaking and length-fixing device for preventing falling connecting rods, which can make the formed rods be broken according to the rod length required by the market, and has high production efficiency.

[0004] An anti-drop baton automatic breaking and length-fixing device comprises an anti-drop baton-connecting mechanism, a breaking and length-fixing mechanism, and a conveying device.

[0005] The anti-drop rod receiving mechanism includes a bracket, a buffer plate, and a roller slideway. The buffer plate and the roller slideway are connected to the bracket. The buffer plate is arranged on the upper part of the bracket, close to the outlet of the long rod. The buffer plate is a plate with a concave and convex curved surface, and slides and rubs with the long rod. The roller slideway includes a plurality of parallel rollers to form a slideway surface. The roller includes a roller shaft and a roller sleeve. Both ends of the roller shaft are connected to the bracket. There is a gap between the roller sleeve and the roller shaft. The roller sleeve can rotate, and the roller sleeve of the roller slideway is frictionally connected with the long rod.

[0006] The breaking and fixing length mechanism comprises a pressing plate, which is an inclined plate, arranged above the long rod, with its lower edge close to the long rod, and both ends of the pressing plate are fixedly connected to the bracket, and the lower end of the roller slide is close to the conveying device. After the long rod extends from the bottom of the roller slide, its lower end is in contact with the conveying device, and the conveying device pushes the long rod to touch the lower edge of the pressing plate, and the long rod is broken and inverted on the conveying device;

[0007] The conveying device comprises a displaceable plane, which is in contact with and connected to the long rod and carries the broken long rod.

[0008] The device also includes a rod-adjusting mechanism, which includes a buffer baffle, the front end of which is close to the long rod outlet and arranged above the long rod, with a gap between the buffer baffle and the extruded long rod, and both ends of the buffer baffle are fixedly connected to the bracket.

[0009] Furthermore, the conveying device is a conveyor belt, which touches the lower end of the long rod and drives it to touch the pressure plate, so that the long rod is broken into short rods; the conveyor belt is connected to the power source.

[0010] The upper surface of the buffer plate is a smooth surface, and the cross-section of the buffer plate is a curve, which is parallel to the axis of the long rod. The curved surface is provided with at least one crest, and the crest position has sliding friction with the long rod, which functions to reduce the contact area between the buffer plate and the long rod, thereby reducing the friction between the surface of the long rod and the plate surface, retaining a small amount of friction so that the long rod will not slide down quickly.

[0011] The bracket includes two side plates, and the two side plates are provided with shaft holes. The two ends of the roller of the roller slideway pass through the side plate shaft holes and are fixed and positioned by retaining rings and cotter pins. A gap is provided between the roller and the shaft hole, and the roller can rotate.

[0012] The roller slideway is a slideway surface formed by the outer circles of multiple sets of roller sleeves, which are in contact with the long rods. The inclination angle of the roller slideway is similar to or consistent with the extrusion angle of the long rods. The roller sleeve is a long round tube and can rotate.

[0013] The lower end of the bracket is fixedly connected to the frame of the conveying device. The conveying device vibrates, driving the bracket to vibrate. The vibration force of the conveying device can be transmitted to the bracket, so that the long rods and the rollers under the long rods are not stuck or bonded, thereby protecting the normal operation of the entire mechanism; further, the upper end of the bracket is fixedly connected to the frame of the roller extruder.

[0014] The pressing plate is fixedly connected to the bracket via an adjustable seat plate, and the fixing position of the adjustable seat plate and the bracket is adjustable. The pressing plate is fixedly connected to the adjustable seat plate via a bolt pair and a pad block. There are multiple pad blocks, which play the role of adjusting the position and angle. The pad blocks are pressed on the upper and lower plate surfaces at both ends of the pressing plate, and the inclination angle of the pressing plate is different from the inclination angle of the long rod.

[0015] Furthermore, the cushion block is provided with an inclined surface, and strip holes are provided at both ends of the pressure plate. The cushion block, the pressure plate and the cushion block are fixed to the adjustable seat plate by a bolt pair.

[0016] Under the action of gravity and the friction force of the long rod, the roller and the rolling sleeve generate eccentric and rotational friction, that is, generate eccentric friction torque, and the long rod extends out under the action of the roller extrusion thrust. When the long rod on the rolling sleeve moves downward, under the action of the eccentric friction torque of the rolling sleeve, the rotation speed of the rolling sleeve is less than the downward movement speed of the long rod, and the rolling sleeve has a damping effect on the long rod; the role of the entire anti-falling rod receiving mechanism is to receive the long rod falling from the upper and lower parts, and to prevent the long rod from falling quickly, and needs to move forward under the action of the roller extrusion thrust; the role of the described rod-smoothing mechanism is to prevent the long rod from warping when it is separated from the roller extrusion and extends to just contact the concave and convex curved surface shape plate, so that it cannot move downward in a straight line correctly, and the device plays a role in limiting the warping;

[0017] When the long rod hits the conveying plane of the conveying device, friction is generated between the long rod and the conveying device. The friction drives the lower end of the long rod to move forward. When the long rod moves forward, it hits the pressure plate. At this time, the rod is broken and conveyed out. The upper long rod continues to move downward and hits the conveying device again, and continues to be broken by force. The height of the pressure plate of the breaking length mechanism is adjustable, so that the rod can obtain the required breaking length.

[0018] The beneficial effects of the present invention are as follows: the entire device has a reasonable structural design, and its main function is to break long rods into rod products of a certain length. When the long rods slide down from the top along the anti-fall rod receiving mechanism and move to contact the conveying device, the long rods are subjected to the friction thrust from the conveying device. This friction thrust causes the rods to tilt forward and move forward. At this time, the top of the rods is blocked by the adjustable pressure plate and is broken. The broken rods fall onto the conveying device with a small drop and are conveyed out. This mechanism greatly reduces the degree of product breakage and improves the yield rate. The position of the pressure plate is adjustable, so that the length of the rods can be adjusted according to needs to achieve the required product purpose. BRIEF DESCRIPTION OF THE DRAWINGS

The conveying device 3 pushes the long rod 4 to touch the lower edge of the pressing plate 2, and the long rod 4 is broken and inverted on the conveying device 3.

[0026] The conveying device 3 comprises a displaceable plane, which is in contact with and connected to the long rod 4 and carries the broken long rod.

[0027] The device also includes a rod-adjusting mechanism, which includes a buffer baffle 5. The front end of the buffer baffle 5 is close to the long rod outlet and is arranged above the long rod 4. A gap is set between the buffer baffle 5 and the extruded long rod 4. Both ends of the buffer baffle 5 are fixedly connected to the bracket 1.

[0028] Furthermore, the conveying device 3 is a conveyor belt, which touches the lower end of the long rod 4 and drives it to touch the pressing plate 2, so that the long rod 4 is broken into short rods; the conveyor belt is connected to a power source.

[0029] The upper surface of the concave-convex curved plate 10 is a smooth surface, and the cross-section of the concave-convex curved plate 10 is a curve, which is parallel to the axis of the long rod 4. The curved surface is provided with at least one crest, and the position of the crest has sliding friction with the long rod, which functions to reduce the contact area between the concave-convex curved plate 10 and the long rod, thereby reducing the friction between the surface of the long rod and the plate surface, retaining a small amount of friction so that the long rod will not slide down quickly.

[0030] The bracket 1 includes two side plates 8, and the two side plates 8 are provided with shaft holes.

[0031] The inclination angle of the roller slideway is close to or consistent with the extrusion angle of the long rod 4; the rolling sleeve 6 is a long round tube, and the rolling sleeve 6 is rotatable.

[0032] The bracket 1 is connected to the vibrating device, and the lower end of the bracket 1 is fixedly connected to the frame of the conveying device 3. The conveying device 3 vibrates by itself, driving the bracket 1 to vibrate. The vibration force of the conveying device 3 can be transmitted to the bracket 1, so that the long rods and the rollers under the long rods are not stuck or bonded, thereby protecting the normal operation of the entire mechanism; further, the upper end of the bracket 1 is fixedly connected to the frame of the roller 9 rod extruder.

When the long rod 4 on the rolling sleeve 6 moves downward, under the action of the eccentric friction torque of the rolling sleeve 6, the rotation speed of the rolling sleeve 6 is less than the downward movement speed of the long rod 4, and the rolling sleeve 6 has a damping effect on the long rod 4; the role of the entire anti-falling rod receiving mechanism is to receive the long rod 4 falling from the upper and lower parts, and to prevent the long rod 4 from falling quickly, and needs to move forward under the action of the extrusion thrust of the roller 9; the role of the described rod-following mechanism is to prevent the long rod 4 from causing the problem of warping when it is extruded and extended from the roller 9 and just contacts the concave-convex curved surface shape plate 10, so that it cannot move downward in a straight line correctly, and the device plays a role in limiting the warping;

[0036] When the long rod 4 hits the conveying plane of the conveying device 3, friction is generated between the long rod 4 and the conveying device 3, and the friction drives the lower end of the long rod 4 to move forward. When the long rod 4 moves forward, it hits the pressure plate 2. At this time, the rod is broken and conveyed out. The upper long rod 4 continues to move downward and hits the conveying device 3 again, and continues to be broken by force.
