Description

Technical Field

[0001] The utility model relates to a feeding station, in particular to a ton bag feeding station. Background Art

[0002] A ton bag is a flexible packaging container. The ton bag feeding station is mainly used to put the materials in the ton bag into a storage bin or production equipment. When in use, generally a hoisting machine is used to transport the ton bag to the ton bag feeding station, the opening of the ton bag is opened, and the ton bag feeding station pats the ton bag to make the materials inside the ton bag fall off. After passing through the ton bag feeding station, the materials are put into the storage bin or production equipment.

[0003] At present, some ton bag feeding stations use clamping plates to clamp the opening of the ton bag to prevent the materials from overflowing into the air and affecting human health. Among them, the two ends of the clamping plate are usually respectively connected with cylinders, and the two cylinders drive simultaneously to make the two ends of the clamping plate descend in parallel to press the opening of the ton bag. In order to improve the sealing effect, some clamping plates are provided with air bags inside, such as the ton bag feeding equipment disclosed in Chinese Utility Model CN215946186U.

[0004] However, the double-cylinder driving method will have the phenomenon that the two cylinders are not synchronized, which will cause the clamping plate to lose balance and lead to the problem of sealing failure. In addition, if there are guide rods for guiding the lifting of the clamping plate on the ton bag feeding station, the guide rods will break due to unbalanced forces on both sides. Summary of the Utility Model

[0005] In order to overcome the disadvantages and deficiencies existing in the prior art, the purpose of the utility model is to design a ton bag feeding station with the function of clamping the opening of the ton bag. The clamping plate of the ton bag feeding station can lift as a whole in balance, so as to avoid the problems of sealing failure and guide rod fracture.

[0006] To achieve the above purpose, the utility model provides a ton bag feeding station, including: a bag patting mechanism, a clamping mechanism, an upper cylinder body, a lower cylinder body, and a straight-through vibrating screen. At least a part of the bag patting mechanism is located above the upper cylinder body. The upper cylinder body, the lower cylinder body and the straight-through vibrating screen are connected in sequence from top to bottom. The clamping mechanism includes: an annular clamping plate, a clamping cylinder, a plurality of guide sleeves and a plurality of guide rods arranged in the up-and-down direction. The clamping plate is located above the upper cylinder body and an annular air bag is arranged inside the clamping plate. The clamping cylinder is connected with the clamping plate to drive the clamping plate to move in the up-and-down direction. It is characterized in that: the clamping plate is fixed to the plurality of guide sleeves, and the guide sleeves are movably arranged on the guide rods in the up-and-down direction and form a tight fit with the guide rods.

[0007] Further, the bag slapping mechanism includes: two bag slapping components, which are arranged axially symmetrically with respect to the vertical midline of the upper cylinder; the bag slapping component includes: a bag slapping cylinder and a slapping plate, the bag slapping cylinder is connected to the slapping plate to drive the slapping plate to move in a direction close to or away from the ton bag, and the slapping plate is located above the upper cylinder. Among them, the two axially symmetrically arranged bag slapping components can slap both sides of the ton bag respectively, improving the efficiency of material dropping.

[0008] Further, the bag slapping component further includes: a buffer rod, and the bag slapping cylinder and the slapping plate are connected through the buffer rod. Among them, setting the buffer rod can play a buffering role, avoiding damage to the ton bag caused by excessive slapping force of the slapping plate.

[0009] Further, the slapping plate is inclined downward from the outside to the inside. Among them, the two inclined slapping plates can keep the ton bag in the central position, avoiding danger caused by the deviation of the ton bag.

[0010] Further, the bulk bag feeding station further includes: several magnetic rods, at least a part of the magnetic rods is located inside the upper cylinder. Among them, the magnetic rods can play a role in removing iron from the material.

[0011] Further, the upper cylinder is provided with several side holes, and the magnetic rods are detachably passed through the side holes and form a tight fit with the side holes. Among them, since the magnetic rods are detachably arranged, it is convenient for users to clean the magnetic rods.

[0012] Further, the bulk bag feeding station further includes: a hose, and the upper cylinder and the lower cylinder are communicated through the hose. Among them, setting the hose can play a shock absorption role, reducing the influence of the vibration of the straight-through vibrating screen on the upper cylinder, and ensuring the sealing between the opening of the ton bag and the upper port of the upper cylinder.

[0013] Further, the bulk bag feeding station further includes: a main support, and the bag slapping mechanism, the clamping mechanism and the lower cylinder are all arranged on the main support. Among them, the main support plays a supporting role for the bag slapping mechanism, the clamping mechanism and the lower cylinder.

[0014] Further, the bulk bag feeding station further includes: a sub-support, and the straight-through vibrating screen is arranged on the sub-support. Among them, the sub-support plays a supporting role for the straight-through vibrating screen. Since the sub-support is separately set to support the straight-through vibrating screen, the influence of the vibration of the straight-through vibrating screen on the main support can be reduced, thereby protecting the main support.

[0015] Further, the bulk bag feeding station further includes: several springs, and the upper end and the lower end of the springs are respectively abutted against the straight-through vibrating screen and the sub-support. Among them, the springs can play a buffering role, thereby protecting the sub-support.

[0016] After adopting the above technical solution, the beneficial effects of the utility model are as follows: Since only one clamping cylinder is used to control the lifting of the clamping plate in the bulk bag feeding station of the utility model, there is no problem of out-of-sync. Moreover, multiple guide sleeves are respectively matched with multiple guide rods, which can ensure the overall balanced lifting of the clamping plate and prevent the breakage of the guide rods at the same time.

The slapping plate 23 is located above the upper cylinder body 4. When the bag slapping mechanism 2 works, the two bag slapping cylinders 21 respectively drive the slapping plate 23 to move through the buffer rod 22, and the ton bag is slapped by the slapping plate 23 to promote the materials inside the ton bag to fall off.

[0025] As a preferred solution, the slapping plate 23 is inclined downward from the outside to the inside. That is, the slapping plate 23 is inclined downward from the edge of the ton bag feeding station to the center.
