Description

Technical Field

[0001] The utility model relates to an adjustable material blocking mechanism for a conveying production line, belonging to the technical field of auxiliary mechanisms of conveying equipment. Background Art

[0002] Currently, woven bags are frequently used in the feed, grain, oil, and food industries for packaging materials. The most commonly used sizes are 5kg, 10kg, and 20kg. When transporting bags along belt or roller conveyors to certain locations, they require a stopper based on the bag's size. This stopper typically uses two splayed openings. The distance between the two ends of the stopper matches the width of the bag. This ensures that the bag remains centered on the conveyor after passing through the stopper.

[0003] Currently, most conveying equipment uses fixed baffles. When conveying materials with different bag sizes, workers need to adjust the distance between the baffles, which is time-consuming and labor-intensive. Alternatively, different conveyor lines are required for materials with different bag sizes, increasing equipment investment. Utility Model Content

[0004] The purpose of the utility model is to overcome the problems existing in the prior art and provide an adjustable material blocking mechanism for a conveying production line, which can automatically adjust the spacing between the ends of the baffles, reduce downtime and labor costs when changing varieties, facilitate the sharing of conveying equipment for packaging bags of different specifications, and reduce equipment investment.

[0005] In order to solve the above technical problems, the utility model provides an adjustable material blocking mechanism for a conveying production line, comprising fixed seats located on both sides of a conveying device, wherein upwardly extending support shafts are fixedly connected to the fixed seats respectively, and the upper portions of the two support shafts are respectively sleeved with shaft sleeves, and the upper and lower ends of the shaft sleeves are respectively hinged to the support shafts through copper sleeves;

[0006] The base of the baffle is fixedly connected to the lower outer periphery of the two shaft sleeves. The two baffles are arranged in an eight-shaped pattern, with their free ends close to each other. The upper outer walls of the two shaft sleeves are respectively welded with ear plates extending to one side, with the two ear plates in opposite directions. The two ends of the connecting rod are respectively provided with joint bearings and are respectively hinged to the free ends of the two ear plates.

[0007] The middle parts of the two baffles are respectively connected with baffle driving rods erected upwards, the upper ends of the two baffle driving rods are respectively connected with laterally extending driving rod ears, and the two ends of the cylinder are respectively hinged on the two driving rod ears.

[0008] The beneficial effects of the utility model are as follows: the adjustable material blocking mechanism has a simple structure, and can realize the change of varieties without manually adjusting the baffle opening spacing, thereby reducing labor costs; the same conveying equipment can alternately convey packaging bags of different specifications, and the switching is convenient. Different functions can be realized under different working conditions, and the conveying equipment can be shared, thereby reducing investment costs. It uses compressed air as clean energy as power and is pollution-free. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In the following description of the present invention, the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not mean that the device must have a specific direction.

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0017] like Figures 1 to 3 As shown, the adjustable material blocking mechanism of the conveying production line of the present invention includes a fixed seat 1, a support shaft 2, a shaft sleeve 3, a copper sleeve 4, an ear plate 5, a connecting rod 6, a spherical bearing 7, a baffle 8, a baffle driving rod 9, a driving rod support ear 10 and a cylinder 11.

[0018] A fixed base 1 is mounted on either side of the conveyor. The lower end of the support shaft 2 is welded to the fixed base 1. A sleeve 3 fits around the outer circumference of the support shaft 2 and is fitted with a copper bushing 4 at each end to reduce wear during rotation around the support shaft 2. Each sleeve 3 is welded with an ear plate 5, positioned in opposite directions. A connecting rod 6, with spherical bearings 7 mounted at each end and hinged to the ear plate 5, ensures synchronous rotation and maintains centering of the two baffles 8. The two baffles 8 are positioned above the conveyor in an "eight" shape, with their openings facing the incoming material. The distal ends of the two baffles 8, or the outlet ends, are close together, with the distance between the openings matching the packaging bag specifications. An upward-standing baffle drive rod 9 is connected to the center of each baffle 8. The upper ends of each baffle drive rod 9 are connected to a laterally extending drive rod lug 10. The bottom of the cylinder 11 and the free end of the piston rod are hinged to the drive rod lugs 10 of the two baffle drive rods 9.

[0019] When conveying small packages, the piston rod of the cylinder 11 contracts, causing the baffle 8 to rotate around the support shaft 2 to reduce the gap at the outlet of the baffle 8; when conveying large packages, the piston rod of the cylinder 11 extends to increase the gap at the outlet of the baffle 8.

[0020] This material blocking mechanism can also be used as a barrier. By simply adjusting the position of the cylinder 11, the material can be blocked at that position when the cylinder 11 contracts, preventing it from moving forward. It can be used to adjust the distance between two packaging bags during material transportation, thereby avoiding the phenomenon of overlapping and connecting bags.

[0021] The above description is only a preferred embodiment of the present invention, which shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It does not limit the scope of patent protection of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. In addition to the above embodiments, the present invention may have other implementation methods without departing from the spirit and scope of the present invention. The present invention may also have various changes and improvements. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention. The scope of protection required by the present invention is defined by the attached claims and their equivalents. The technical features not described in the present invention can be achieved by or using existing technologies, and will not be described here.
