Description

Technical Field

[0001] The invention relates to a transport device, in particular to an auxiliary device for transporting bag-shaped products. Background Art

[0002] The production of cemented carbide requires a variety of raw materials (such as barreled tungsten carbide). The raw materials are packed in bags, which are placed inside barrels. Since the barrels are in contact with the ground, in order to prevent dust and stains on the ground from being transferred with the barrels, usually only the bagged raw materials are transported. The bagged raw materials will be hung above the weighing barrel of the batching equipment to pour out the raw materials, or the bagged raw materials will be transported to the production line. In order to avoid leakage of raw materials and to facilitate cooperation with the clamp, the bag will be knotted and sealed at the upper opening of the bag.

[0003] Generally, a self-weight clamp is used to clamp the knot on the upper end of the bag. When the bagged raw materials are moved to the top of the weighing barrel of the batching equipment, the staff will separate the bag to unload the materials. As the raw materials are poured out, the weight of the bag containing the raw materials will gradually decrease, and the clamping effect of the clamp will also decrease. There is a possibility that the bag will break away from the clamp, making it difficult to clamp, transport and transfer it. Summary of the invention

[0004] The object of the present invention is to provide a bag-shaped product carrying auxiliary device which is easy to use and has a better clamping effect.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a bag-shaped product handling auxiliary device, including a fixed frame used to connect with a handling mechanism, the fixed frame is provided with two relatively arranged swinging members, the distance between the upper ends of the two swinging members is smaller than the distance between the lower ends of the two swinging members, the lower ends of the swinging members are rotatably connected to the fixed frame, the two swinging members are linked by a linkage connecting rod assembly, the linkage connecting rod assembly is equipped with a telescope, one end of the telescope is rotatably connected to the linkage connecting rod assembly, and the other end of the telescope is rotatably connected to the fixed frame, the telescope is extended or retracted to make the two swinging members swing synchronously, so that the upper ends of the two swinging members swing around their own lower ends and move away from or close to each other.

[0006] After the bag-like product is clamped by the device of the present invention, the fixed frame is moved by the conveying mechanism to the top of the bag-like product, and then the worker operates so that the knot at the upper end of the bag-like product is located between the upper ends of the two swinging parts, and the knot is located above the swinging parts; then the telescopic device is started to control the closing of the two swinging parts, or the closing of the two swinging parts is directly carried out manually, and then the bag-like product is moved by the conveying mechanism, and is released by the telescopic device after being moved to the specified position.

[0007] The present invention is provided with a telescopic device that can realize the synchronous swinging of two swinging parts. Not only can the clamping be realized by its own weight, but the two swinging parts can also be closed by the telescopic device, so the clamping and fixing effect is better and it is more convenient to use. By providing the telescopic device, there is no need to use a conveying mechanism to assist in the lifting of the device for clamping, so it is suitable for bag products with a small space below the knot at the upper end of the bag body, and has a wider range of applications. Among them, the telescopic device of the present invention can adopt a cylinder, an electric push rod, a gas spring, or a telescopic rod. In the process of clamping and transferring, the bag body will have an inward and downward moving tendency due to the self-weight of the bag body, thereby ensuring the clamping effect. Even if the bag body is cut to allow the product to be poured out, the use of the telescopic device can ensure that the swinging part clamps the bag body.

[0008] Preferably, the fixed frame is formed with a makeshift space running through from top to bottom, the swinging member is located in the makeshift space, the swinging member includes a rotating part rotatably connected to the fixed frame, the rotating part is connected to one end of the extension part, the other end of the extension part extends upward, the deviated end of the extension part is rotatably connected to the upper end of a first connecting rod, the lower ends of the two first connecting rods are respectively rotatably connected to one end of the second connecting rod, the telescope is connected to one end of the rocker rod, and the other end of the rocker rod drives the second connecting rod to move upward or downward under the action of the telescope.

[0009] The connection between the first connecting rod and the second connecting rod can realize the linkage between the swing member and the telescope, which improves the synchronization and accuracy of the clamping action. The design of the clearance space allows the swing member to move inside the fixed frame, reducing the external dimensions of the device, making the device more compact and easy to install and operate. The fixed frame is composed of a clearance space that runs through the top and bottom. Compared with conventional clamps that clamp by their own weight, the structure has higher stability and higher bearing capacity.

[0010] Preferably, the second connecting rod is provided with a transversely extending guide groove, and the end of the swing rod has a linkage protrusion extending into the guide groove. The cooperation between the linkage protrusion and the guide groove can ensure the accurate guidance of the swing rod during the extension and retraction process, reduce errors, improve the reliability of clamping, and achieve rapid release and clamping.

[0011] Preferably, the swing rod is tilted and L-shaped, and includes a first swing rod section connected to the second connecting rod and a second swing rod section connected to the telescope, the left end of the telescope is rotatably connected to the fixed frame, the right end of the telescope is connected to the second swing rod section, and the first swing rod section and the second swing rod section both extend away from the second end of the telescope. The telescope of the present invention is arranged horizontally, which can ensure the opening and closing effect between the two swinging parts in a compact structure.

[0012] Preferably, a friction block is fixed on the upper end of the swinging member. The friction block is provided to increase the clamping friction force on the bag-shaped product, prevent the bag from slipping during transportation, and improve safety; the friction block of the present invention can be a plastic block, which is fixed to the upper end of the swinging member by a fastener.

[0013] Preferably, the friction block is cylindrical. The cylindrical friction block can provide uniform contact pressure, reduce damage to bag-shaped products, and improve the stability of clamping; when the friction block is severely deformed, the friction block can be removed and then rotated so that the intact part of the friction block can be used for clamping.

[0014] Preferably, the retractor is a gas cylinder. Using a gas cylinder as a retractor can control the retracting and expanding by utilizing the change of gas pressure, and the operation is simple, the response speed is fast, and the maintenance cost is low.

[0015] The present invention has the advantages of being easy to use and having a better clamping effect. BRIEF DESCRIPTION OF THE DRAWINGS
