Description

TECHNICAL FIELD

[0001] The present application belongs to the field of mechanical processing, and particularly relates to a bidirectional linkage material blocking mechanism. BACKGROUND

[0002] The existing transplanting mechanism for feeding and discharging needs to set a set of material blocking mechanism in the feeding and discharging directions to coarsely position and protect the material. This scheme needs to avoid interference with the conveying line body, and the power direction of the material blocking mechanism can only be perpendicular to the conveying direction. The stress direction of the mechanism is vertical, and the movement direction of the conveying line body is horizontal. When the material blocking mechanism is blocked, the impact is completely borne by the vertical power mechanism, which is unreasonable. Moreover, due to the limitation of the conveying line body parts, the traditional material blocking mechanism is only set below or outside the conveying line body, which increases the installation space. Two sets of material blocking mechanisms need to be set in the other two directions, which causes the overall equipment to be redundant and increases the cost. SUMMARY

[0003] The purpose of the present application is to provide a bidirectional linkage material blocking mechanism which utilizes the dead point of the circular arc groove and the bidirectional linkage of the double-rod cylinder to reduce the complexity of the mechanism and improve the stress direction of the mechanism, thereby overcoming the problems of unreasonable stress of the existing one-way single-action material blocking mechanism, increased installation space, and overall redundant conveying equipment and increased cost.

[0005] A guide rod is arranged horizontally at the bottom of the mounting seat, and the circular arc groove slider is slidingly arranged on the guide rod.

[0006] The guide rod is provided with two parallel guide rods.

[0007] An oil-free bushing is installed in the guide hole on the circular arc groove slider, and the oil-free bushing is sleeved on the guide rod.

[0008] The bidirectional linear driving mechanism is a double-rod cylinder.

[0009] The piston rod of the double-rod cylinder is connected with the circular-arc groove slider through a cylinder connecting rod.

[0010] The cylinder body of the double-rod cylinder is fixed on a cylinder support.

[0016] 3. The present application utilizes the special position of the circular-arc groove dead point, so that the impact of the workpiece on the blocking block is converted into horizontal force on the dead point.

[0021] The present application will be further described in detail below in combination with the drawings and examples, but it is not used as the basis for any limitation on the application. ​

[0022] Referring to the drawings Figure 1 , 2 As shown in the drawings, a bidirectional linkage material blocking mechanism includes a mounting seat 1, a guide rod 2, a circular arc groove sliding block 3, a drag rod 4, a blocking block 5, a limiting rod 6, a cylinder connecting rod 7 and a double-rod cylinder 8.

[0023] The mounting seat 1 is a rectangular parallelepiped with an open top, and two horizontal guide rods 2 are mounted inside the mounting seat 1. The two guide rods 2 are parallel, and the two ends of the guide rods 2 are fixed to the inner wall of the mounting seat 1. The circular arc groove sliding block 3 is slidingly arranged on the two guide rods 2, and preferably, an oil-free bushing is mounted in the guide hole at the bottom of the circular arc groove sliding block 3 to ensure smoother movement of the sliding block on the guide rod 2.

[0024] The guide rod 2 is made of a hardened mandrel that is precisely drawn to ensure assembly accuracy and stable operation of the mechanism. The oil-free bushing matched with the circular arc groove sliding block 3 is a standard part that can be easily purchased on the market and can be used as a vulnerable part to protect other non-standard processed parts, thereby greatly reducing the maintenance level and cost of customers.

[0025] Alternatively, other formed tracks can be arranged in the mounting seat 1, and the circular arc groove sliding block 3 is slidingly arranged on the tracks. For example, a sliding rail can be arranged, and a corresponding groove is arranged at the bottom of the circular arc groove sliding block, the groove and the sliding rail are in convex-concave cooperation, and linear sliding is achieved.

[0026] The circular arc groove sliding block 3 is of a plate frame structure, having a bottom plate, an end plate and two side plates. One bottom plate and one end plate are arranged respectively, and the bottom plate is provided with the guide hole and the oil-free bushing. The two side plates are arranged on the left and right sides of the bottom plate respectively, and the end plate is connected with the bottom plate and the two side plates. The piston rod of the double-rod cylinder 8 is connected with the end plate through the cylinder connecting rod 7, so that the piston rod drives the circular arc groove sliding block 3 to slide linearly along the guide rod 2.

[0027] The upper part of the side plate of the circular arc groove sliding block 3 is provided with a circular arc groove 3-1, and the circular arc grooves 3-1 on the two side plates are symmetrically arranged. A drag rod 4 is arranged in the circular arc groove 3-1, and the drag rod 4 is connected with a connecting hole at one end of the blocking block 5.

[0028] The blocking block 5 is further provided with a connecting hole for mounting the limiting rod 6, and the limiting rod 6 passes through the side plate of the mounting seat 1 and is axially limited by a shaft retaining ring.

[0029] For the mounting seat 1, the circular arc groove sliding block 3 drives the drag rod 4 in the circular arc groove 3-1 during horizontal sliding, and the drag rod 4 drives the blocking block 5. However, the blocking block 5 is fixed on the mounting seat 1 by the limiting rod 6, so that the blocking block 5 can only rotate around the axis of the limiting rod 6 as the rotating shaft to make circular motion, thereby ingeniously converting the horizontal motion of the cylinder into the circular motion of the blocking block 5, realizing the lifting and lowering of the blocking end of the blocking block 5, and achieving the functions of blocking and discharging materials.

[0030] The circular-arc groove slider 3 drives the stopper 5 to make circular motion through the drag link 4, and the material blocking end of the stopper 5 is lifted and exposed to the mounting seat 1 to block the material. The drag link 4 is just inserted into the upper end of the circular-arc groove 3-1, which is the dead point of the circular-arc groove slider 3. The impact of the workpiece on the stopper 5 in the horizontal direction is converted into the horizontal force on the dead point, and the cylinder connected to the circular-arc groove slider 3 is in the extended state, which is locked in the horizontal direction, and the force on the dead point is completely offset.

[0031] When the piston rod at one end of the double-rod cylinder 8 is extended, the piston rod at the other end is retracted, so that the piston rods at both ends of the double-rod cylinder 8 are connected to a circular-arc groove slider 3 respectively. When the workpiece is fed along the conveying line body to the right side, the double-rod cylinder 8 drives the left circular-arc groove slider 3 to move, so that the connected stopper 5 rotates, and the material blocking end of the stopper 5 descends into the mounting seat 1 to allow the workpiece to pass through. At the same time, the right stopper 5 is lifted to block the material. Conversely, one cylinder controls the simultaneous lifting and lowering of the material blocking ends of two stoppers 5, which is logically matched with the feeding and discharging logic of the conveying line.

[0032] The material blocking end of the stopper is provided with a slope, wherein the slope of the stopper located at the feeding end faces the direction of the incoming workpiece, and the slope of the stopper located at the discharging end faces the direction of the workpiece leaving the conveying line body.

[0033] Optionally, in other embodiments, a double-rod oil cylinder or other bidirectional linear driving mechanism can be used to replace the double-rod cylinder of the present embodiment, which can also have the same effect.

[0034] As shown in Figure 3 When installing, the material blocking mechanism of the present application is installed on both sides of the conveying line body 9, the mounting seat 1 is fixed on the rack of the conveying line body 9, the cylinder body of the double-rod cylinder 8 is fixed on the base 10, and the base 10 is fixed on the rack. After installation, the upper surface of the mounting seat 1 is lower than the conveying surface of the conveying line body 9, and the material blocking end of the stopper 5 is lifted and higher than the conveying surface. The conveyed workpiece will be blocked by the stopper 5 due to the large width size, so that the stopper 5 can block the material. The working process of the present application is as follows:

[0035] When the conveying line body 9 feeds to the right, the arc slot slider 3 in the mounting seat 1 on the left is pulled by one end of the double-rod cylinder 8 through the cylinder connecting rod 7, and moves stably and horizontally on the two guide rods 2. The horizontal movement of the arc slot slider 3 drags the drag rod 4 to move through the smooth arc slot 3-1, and the drag rod 4 is matched with the stop block 5 through the limiting rod 6, and the stop block 5 is limited on the mounting seat 1 by the limiting rod 6, so that the horizontal movement of the arc slot slider 3 is converted into the circular movement of the stop block 5 with the limiting rod 6 as the rotation axis, so that the left stop block 5 rotates, and the material blocking end is lowered into the mounting seat 1 to release the workpiece for feeding; at this time, the right movement is just the opposite, and the material blocking end of the stop block 5 is lifted, so as to block the incoming material and coarsely position.

[0036] When the workpiece feeding is finished, the double-rod cylinder moves reversely, at this time, the material blocking end of the right stop block 5 is lowered into the mounting seat 1, and the conveying line body releases the material, and the material blocking end of the left stop block 5 is lifted to expose the mounting seat 1, and waits for the conveying line body to feed.

[0037] The present application converts the horizontal movement of the double-rod cylinder 8 into the circular movement of the stop block 5 by adopting the arc slot slider 3, solves the problem that the traditional material blocking mechanism needs to be installed on the conveying line body to occupy space, more ingeniously utilizes the characteristics of the arc slot dead point to greatly improve the damage caused by the impact of the workpiece on the material blocking mechanism, and realizes that a set of power mechanism completes the operation of two sets of material blocking mechanisms, and effectively cooperates with the bidirectional conveying conveying line body to realize stable, safe and automatic operation.

[0038] The above examples are only used to illustrate the technical solutions of the present application, but not to limit it, and those skilled in the art should understand that the specific embodiments of the present application can be modified or replaced by the same, and any modification or equivalent replacement without departing from the spirit and scope of the present application is within the protection scope of the claims.
