Abstract
Description
Technical Field
[0001] This utility model relates to the field of cardboard conveying equipment, and in particular to a cardboard corner parallel conveyor belt. Background Technology
[0002] Existing corner conveyor belts or corner roller conveyors are generally only suitable for handling heavy goods. For lighter or thinner goods, such as cardboard, due to their light weight, they will rotate and shift irregularly under the influence of inertia and complex external forces when passing through the corner area. Therefore, current conveyor belts cannot accommodate cardboard. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a cardboard corner parallel conveyor belt that enables the cardboard to not rotate, but only to perform a specified translation, so as to transfer it to other equipment as required.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is a cardboard corner parallel conveyor belt, including a conveyor frame, a conveyor belt, a movable paper pressing wheel, and a deceleration paper pressing strip. The number of conveyor belts is at least one set. The conveyor belt is inclinedly arranged on the inner side of the conveyor frame from the front end to the rear end. The upper surface of the front end of the conveyor belt is arranged with a deceleration paper pressing strip and a movable paper pressing wheel in sequence from front to back. The movable paper pressing wheel can move back and forth along both sides of the conveyor frame. The straight line formed by the overlapping edges of the movable paper pressing wheels is parallel to the edge line of the conveyor belt.
[0005] In a further improvement, the sides of the front and rear ends of the conveyor belt are spaced a certain distance from the sides of the corresponding conveyor frame.
[0006] In a further improvement, the deceleration paper pressing strip is a curved, elastic strip structure.
[0007] In a further improvement, the movable paper pressing rollers comprise two rows arranged front and rear.
[0008] In a further improvement, each set of movable paper-pressing rollers is mounted on the conveyor frame via a track assembly. The track assembly includes a gear, a rack, a limiting rod, a sliding seat, a gear shaft, and a handwheel. The rack and the limiting rod are fixed parallel to each other on a frame on one side of the conveyor frame, with the limiting rod located on the outer side and the rack on the inner side. A movable sliding seat is provided on the limiting rod. A gear is installed near the end of the gear shaft, and the gear meshes with the rack. The end of the gear shaft outside the gear passes through the sliding seat and a handwheel is installed on its end. At least two movable paper-pressing rollers are hinged at the middle position of the gear shaft.
[0009] In a further improvement, the movable paper pressing wheel is mounted on the gear shaft via a hinge assembly. The hinge assembly includes a retaining ring, a rocker arm, a pin, and a concentric support column. The concentric support column is hinged to the gear shaft, and retaining rings are provided on both sides of the hinge position. A rocker arm is hinged to the bottom of the end of the concentric support column away from the gear shaft, and the movable paper pressing wheel is hinged to the side of the end of the rocker arm after it is bent.
[0010] Further improvements include the provision of at least one set of fixed paper-pressing rollers on the upper surface of the rear end of the conveyor belt, with the straight line formed by the overlapping edges of the fixed paper-pressing rollers being parallel to the edge line of the conveyor belt.
[0011] In a further improvement, an adjustment device is provided at the bottom of the conveyor belt. The adjustment device includes an assembly, a first roller, and a second roller. The assembly is installed parallel to the bottom of the conveyor belt. The first roller and the second roller are installed between the assembly in a staggered and parallel manner. The side of the conveyor belt formed by the conveyor roller, the first roller, and the second roller at the starting end of the conveyor belt is triangular in shape. The conveyor belt passes around the bottom of the first roller and the top of the second roller at the starting end and merges with the end end.
[0012] By adopting the above technical solution, by setting a deceleration pressure strip and a moving pressure roller, and by setting the moving pressure roller to be able to move back and forth, and further by making the straight line formed by the overlapping edges of the moving pressure roller parallel to the edge line of the conveyor belt, it is ensured that under different conveyor belt turning angles, the cardboard will not rotate or shift due to inertial force and complex external force under the combined action of the deceleration pressure strip and the moving pressure roller, thereby ensuring the normal operation of the production process.

Detailed Implementation
[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0018] This invention discloses a cardboard corner parallel conveyor belt 2, comprising a conveyor frame 1, a conveyor belt 2, a movable paper pressing roller 3, and a deceleration paper pressing strip 4. The number of conveyor belts 2 is at least one set; this embodiment uses two sets of conveyor belts 2. However, this is not a limitation but an example; more sets or only one set can be used depending on site conditions or production needs. The two sets of conveyor belts 2 are arranged parallel inside the conveyor frame 1, inclined forward and backward, with an adjustable angle relative to the edge frame of the conveyor frame 1. The corner angle can be adjusted according to different production spaces, as long as the installation relationship with the conveyor belts 2 is satisfied. The conveyor belts 2 can be conventional conveyor belts, and their specific structure is not limited. Furthermore, the front and rear ends of the conveyor belt 2 are spaced a certain distance from the sides of the corresponding conveyor frame 1 to avoid the edge of the conveyor frame 1 affecting the conveying of cardboard 8 on the conveyor belt 2.
[0019] To facilitate the tension adjustment of the conveyor belt 2, an adjustment device 5 is provided at the bottom of the conveyor belt 2. The adjustment device 5 includes an assembly 51, a first roller 52, and a second roller 53. The assembly 51 is installed in parallel under the bottom frame of the conveyor belt 2, that is, the assembly 51 is installed in pairs. The assembly 51 is in a triangular shape. One angle position of the assembly 51 is fixed to the frame of the conveyor belt 2, while the first roller 52 and the second roller 53 are installed at the other two angle positions of the assembly 51. The first roller 52 and the second roller 53 are arranged in parallel and are staggered in height. The side of the first roller 52, the second roller 53 and the conveyor roller at the starting end of the conveyor belt 2 forms a triangular shape. One end of the conveyor belt 2 passes around the bottom of the first roller 52 and the top of the second roller 53 in sequence and merges with the other end. With the adjustment device 5, when the conveyor belt 2 is not tight enough, the assembly 51 can be adjusted and rotated at a certain angle to increase the height difference between the bottom of the first roller 52 and the second roller 53, thereby making the conveyor belt 2 tight. Conversely, the height difference between the bottom of the first roller 52 and the second roller 53 can be reduced to make the conveyor belt 2 loose.
[0020] The upper surface of the front end of the conveyor belt 2 is provided with a deceleration paper pressing strip 4 and a moving paper pressing wheel 3 from front to back. The deceleration paper pressing strip 4 is a curved elastic strip structure, which can be a long strip of thin iron sheet or other elastic material that can decelerate the paper without causing the cardboard to shift.
[0021] The movable pressure roller 3 is designed to move back and forth along both sides of the conveyor frame 1. The straight line formed by the overlapping edges of the movable pressure roller 3 is parallel to the edge line of the conveyor belt 2. This design ensures that the conveyor belt 2 is tilted, and that when turning corners, the cardboard can be conveyed normally under the drive of the movable pressure roller 3. This invention does not limit the specific installation structure of the movable paper pressing roller 3 to be movable forward and backward, as long as it can meet the normal forward and backward movement. In this embodiment, the movable paper pressing roller 3 is installed on the conveyor frame 1 through the track assembly 6. The track assembly 6 includes a gear 61, a rack 62, a limiting rod 63, a sliding seat 64, a gear shaft 65, and a handwheel 7. The rack 62 and the limiting rod 63 are fixed parallel to each other on the frame on one side of the conveyor frame 1. The limiting rod 63 is located on the outside, and the rack 62 is located on the inside. The limiting rod 63 is provided with a movable sliding seat 64. A gear is installed near the end of the gear shaft 65. The gear meshes with the rack 62. The end of the gear shaft 65 outside the gear passes through the sliding seat 64 and a handwheel 7 is installed on its end. At least two movable paper pressing rollers 3 are provided in the middle position of the gear shaft 65 by means of hinge, that is, two parallel movable paper pressing rollers 3 are provided on one gear shaft 65 of one conveyor belt 2. In this embodiment, because two sets of parallel conveyor belts 2 are arranged, they can share a single gear shaft 65. Specifically, two parallel moving paper-pressing rollers 3 are mounted on the gear shaft 65 of one set of conveyor belts 2, and the other set of conveyor belts 2 is similarly configured. The two sets of parallel moving paper-pressing rollers 3 help maintain balanced and stable conveying of the cardboard. To ensure stable conveying of cardboard of different lengths, an additional row of moving paper-pressing rollers 3 can be added, positioned behind the first row of moving paper-pressing rollers 3, thus forming two rows of moving paper-pressing rollers 3 connected by two parallel gear shafts 65. The two rows of moving paper-pressing rollers 3 are identical in structure except for their installation position.
[0022] To further adapt to conveying at different turning angles, the movable paper pressing roller 3 of the present invention is mounted on the gear shaft 65 via a hinge assembly. The hinge assembly includes a retaining ring 71, a swing rod 74, a pin 73, and a concentric support column 72. The concentric support column 72 is hinged to the gear shaft 65, and retaining rings 71 are provided on both sides of the hinge position. The bottom of the end of the concentric support column 72 away from the gear shaft 65 is hinged to the swing rod 74 via the pin 73. The movable paper pressing roller 3 is hinged to the side of the end of the swing rod 74 after it is turned.
[0023] The concentric support column 72 is hinged, allowing the gear shaft 65 to slide back and forth when the handwheel 7 rotates, through the engagement of the gear and rack 62. Due to the hinged connection, the movable pressure roller 3 can slide back and forth without rotating with the gear shaft 65. The retaining ring 71 limits the concentric support column 72, ensuring it is fixed in a specific installation position. The retaining ring 71 can be fixed (e.g., directly welded) or detachable, as long as it can be fixed to both sides of the concentric support column 72 without displacement. A swing arm 74 is hinged to the bottom of the end of the concentric support column 72 furthest from the gear shaft 65. The swing arm 74 has a hinged structure, and the movable pressure roller 3 is hinged to the side of its end. This allows the swing arm 74 to swing according to the tilt angle of the conveyor belt 2, ensuring that the straight line formed by the overlapping edges of the movable pressure roller 3 is always parallel to the edge line of the conveyor belt 2, thus achieving stable paperboard transport.
[0024] In order to further stabilize the conveying of the cardboard, at least one set of fixed pressure rollers 9 are provided on the upper surface of the rear end of each conveyor belt 2. The fixed pressure rollers 9 are also hinged to the fixed rods installed on the conveyor belt 2 using the above-mentioned hinge assembly, and the straight line formed by the overlapping edges of the fixed pressure rollers 9 is parallel to the edge line of the conveyor belt 2.
[0025] Similarly, a row of fixed paper-pressing rollers 9 can be set at the rear end of the conveyor belt 2, one at the front and one at the back, to further constrain the conveying of the paperboard.
[0026] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
