Description

TECHNICAL FIELD

[0001] The present application relates to a carrying device, in particular to a bag-shaped product carrying auxiliary device. BACKGROUND

[0002] In the production of hard alloy, a variety of raw materials (such as barreled tungsten carbide) are needed, which are loaded in the barrel, and the bag is located in the barrel. In order to avoid the transfer of dust and stains on the ground with the barrel, only the bagged raw materials are usually carried, which are hung above the weighing barrel of the batching equipment for raw material pouring, or carried to the assembly line. In order to avoid raw material leakage and facilitate cooperation with the clamp, a knot is tied at the opening of the upper end of the bag.

[0003] Generally, a self-weight clamp is used to clamp the knot at the upper end of the bag. When the bagged raw materials are moved above the weighing barrel of the batching equipment, the worker separates the bag to pour the raw 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, so that the bag may be separated from the clamp, and it is difficult to use the clamping method for carrying and transferring. SUMMARY

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

[0005] To achieve the above purpose, the technical scheme adopted by the present application is as follows: a bag-shaped product carrying auxiliary device, comprising a fixing frame for connecting with a carrying mechanism, two opposite swing members are arranged on the fixing frame, the distance between the upper ends of the two swing members is less than the distance between the lower ends of the two swing members, the lower ends of the swing members are rotationally connected with the fixing frame, the two swing members are linked through a linkage link assembly, the linkage link assembly is matched with a telescopic device, one end of the telescopic device is rotationally connected with the linkage link assembly, the other end of the telescopic device is rotationally connected with the fixing frame, the telescopic device is extended or retracted to make the two swing members swing synchronously, so that the upper ends of the two swing members swing around the lower ends as the center and move away from or close to each other.

[0006] After the bag-shaped product is clamped by the device of the present application, the movement of the fixing frame is realized by the carrying mechanism, the fixing frame is moved above the bag-shaped product, then the worker operates to make the knot at the upper end of the bag-shaped product located between the upper ends of the two swing members, and the knot is located above the swing members; then the telescopic device is started to control the closing of the two swing members, or the closing of the two swing members is directly operated manually, then the movement of the bag-shaped product is realized by the carrying mechanism, and the telescopic device is released after the bag-shaped product is moved to the specified position.

[0007] The present application is provided with a telescopic device capable of realizing synchronous swinging of two swinging members, which can not only realize clamping through self weight, but also realize folding of two swinging members through the telescopic device, so that the clamping and fixing effect is better and the use is more convenient; through the telescopic device, auxiliary clamping through lifting of the carrying mechanism is not needed, which is suitable for bag body products with small space below the knot at the upper end of the bag body, and the application range is wider. The telescopic device of the present application can adopt a pneumatic cylinder, an electric push rod, or a gas spring, and can also adopt a telescopic rod. During the clamping and transferring process, the bag body will drive the swinging member to have a moving tendency force towards the inside and downwards due to the self weight, so as to ensure the clamping effect; even if the bag body is cut to make the product be poured out, the clamping of the swinging member to the bag body can also be ensured due to the use of the telescopic device.

[0008] As a preferred, the fixed frame is provided with a through upper and lower accommodation space, the swinging member is located at the accommodation space, the swinging member includes a rotating part rotatably connected with the fixed frame, the rotating part is connected with one end of an extension part, the other end of the extension part extends upwards, the extension part is rotatably connected with the upper end of a first connecting rod at the deviated end, the lower end of the two first connecting rods is rotatably connected with one end of a second connecting rod, the telescopic device is connected with one end of a swinging rod, the other end of the swinging rod drives the second connecting rod to move upwards or downwards under the action of the telescopic device.

[0009] Through the connection of the first connecting rod and the second connecting rod, the linkage between the swinging member and the telescopic device can be realized, and the synchronism and accuracy of the clamping action are improved. The design of the accommodation space enables the swinging member to move inside the fixed frame, reduces the external size of the device, and makes the device more compact, facilitating installation and operation. The fixed frame is provided with a through upper and lower accommodation space, compared with the conventional clamps relying on self weight for clamping, the structural stability is higher and the bearing capacity is higher.

[0010] As a preferred, the second connecting rod is provided with a transversely extending guide groove, and the end of the swinging rod has a linkage protrusion extending into the guide groove. The cooperation of the linkage protrusion and the guide groove can ensure the accurate guidance of the swinging rod during the telescoping process, reduce errors, improve the reliability of clamping, and realize quick loosening and clamping.

The telescopic device of the present application is transversely arranged, which can ensure the opening and folding effect between the two swinging members in the case of compact structure.

[0012] As preferred, the upper end of the swing member is fixed with a friction block. The friction block is arranged to increase the clamping friction force on the bag-shaped product, prevent the bag from slipping off during the carrying process, and improve safety. The friction block of the present application can be a plastic block, which is fixed on the upper end of the swing member by a fastener.

[0013] As preferred, the friction block is cylindrical. The cylindrical friction block can provide uniform contact pressure, reduce damage to the bag-shaped product, and improve clamping stability. When the friction block is partially deformed, the friction block can be removed and rotated to use the intact part of the friction block for clamping.

[0014] As preferred, the telescopic device is a pneumatic cylinder. The use of a pneumatic cylinder as a telescopic device can control the telescopic movement by using the change of air pressure, which is easy to operate, fast in response, and low in maintenance cost.

[0015] The present application has the advantages of easy use and better clamping effect. BRIEF DESCRIPTION OF DRAWINGS
