Description

Technical Field

[0001] The utility model relates to the technical field of salt bagging control equipment, in particular to a control device for receiving materials at a bag mouth of a large bag used for salt bagging. Background Art

[0002] In the existing process of bagging finished salt products, in the traditional technical field, enterprises of a certain scale still use a semi-manual method of automatic metering and manual bag sewing, that is, the packaging bag is opened manually and placed on the bag rack of the discharge pipe, and then the bagging switch is manually turned on. After the quantitative filling is completed, the bagged objects are moved manually and the bag sewing machine is used to sew. This bagging method is first of all inefficient. After filling one bag, the next bag can only be started after the feed bag is moved, and each link requires manual work, which wastes manpower and material resources. The weighing and bagging devices in the existing technology all use one-time weighing to bag and seal the bags, and there is a certain distance between the discharge port of the silo and the raw material bag, which may cause the loss of raw materials and weighing errors. It is difficult to achieve the purpose of effectively controlling the salt filling process, which has certain inconveniences. To this end, we propose a control device for receiving materials at the bag mouth of a large bag for bagging salt. Utility Model Content

[0003] The utility model aims to provide a control device for receiving materials at the bag mouth of a large bag for bagging salt, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a control device for receiving materials at the bag mouth of a large bag for bagging salt, comprising a base, a conveyor belt is installed on the base, and two sets of limit plates are arranged in parallel on the conveyor belt, a feed barrel is installed above the conveyor belt through a mounting bracket, a discharge pipe is arranged below the feed barrel, an inclined weighing plate is arranged in the discharge pipe, and a solenoid valve is arranged at the discharge port of the discharge pipe, splints are arranged on both sides of the mounting bracket, a moving block is arranged on the side of the splint, the moving block is connected to the first telescopic rod through a connecting rod, a baffle is arranged on the outer side of the splint, and the side of the baffle is connected to the second telescopic rod.

[0005] In the above solution, the conveyor belt is rotatably installed in the positioning bracket.

[0006] In the above solution, a support rod is provided below the feeding cylinder.

[0007] In the above solution, a sleeve is provided on the connecting rod, and the sleeve is movably sleeved on the guide rod.

[0008] In the above solution, a resistance wire is arranged inside the clamping plate.

[0009] In the above solution, a power supply and a control panel are provided on the base.

[0010] In the above solution, the position of the clamping plate is higher than the top surface of the limiting plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the control device for receiving materials at the bag mouth of the large bag material for bagging salt has a simple and reasonable structural design and is highly practical. The salt bag body is automatically transported by a conveyor belt installed inside the positioning bracket, and the bag body is constrained by an elastic limiting plate so that the head of the bag body to be packaged is higher than the limiting plate, which is convenient for subsequent clamping and packaging by a clamping plate. The operation is convenient and simple, and the practicability is strong. By arranging a feeding barrel and a discharging pipe as a loading mechanism, the material can be weighed under the action of a weighing plate obliquely arranged inside the discharging pipe. For the purpose of weighing, when used in conjunction with a solenoid valve, salt weighed to an accurate weight can be added to the inside of the bag, thereby reducing errors and achieving more accurate weighing. By setting up a guide rod, a sleeve, a moving block, a splint and a first telescopic rod and other structures for use in conjunction, the two splints can be driven to seal the bag opening from both sides at the same time, and the splints are heated under the action of a resistance wire, thereby improving the sealing effect on the bag opening. By setting up a second telescopic rod in conjunction with a baffle, as a limiting mechanism, only a single bag is allowed to pass through in a short time, thereby avoiding the bag being transported too fast, causing the bag to overlap and affecting the sealing accuracy.
