Description

Technical Field

[0001] This application relates to the field of cardboard conveying technology, and more particularly to a cardboard conveyor. Background Technology

[0002] Paperboard, also known as cardboard, is a thick sheet of paper made from various pulps, composed of interwoven fibers. The difference between paperboard and regular paper is usually distinguished by basis weight and thickness. Paperboard is the main material for making packaging products, and it requires conveying equipment before processing.

[0003] A typical cardboard conveying system usually has a track on the frame, a rotating rod on the track, a transmission rod on the rotating rod, and a guide wheel at the end of the transmission rod. The guide wheel moves up and down along the rotating rod along with the transmission rod. A moving track with a cardboard detection device is located at the right end of the track. The cardboard is conveyed via the track, and the guide wheel adjusts the position of the cardboard on the track, avoiding manual adjustment before feeding. The cardboard detection device checks the cardboard specifications to prevent defective cardboard from entering the equipment and producing substandard products, thus improving work efficiency. Auxiliary tracks can be added to accommodate equipment of various heights.

[0004] The above solution cannot adjust the feeding spacing according to the width of the cardboard in actual use. This causes the cardboard to be skewed or displaced on the conveying device when conveying narrower cardboard, making it impossible for the cardboard to enter the subsequent processing equipment neatly, which has certain limitations. Utility Model Content

[0005] This application discloses a cardboard conveyor, which aims to solve the technical problem that existing cardboard conveying devices cannot adjust the feeding distance.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A cardboard conveyor includes a base, two symmetrical vertical plates are provided on the upper surface of the base, a conveying mechanism is provided between the two vertical plates, a spacing adjustment mechanism is provided between the vertical plates and the base, and a transfer mechanism is provided on the lower surface of the base.

[0008] The conveying mechanism includes two rotating rods rotatably connected to one side surface of the vertical plate, a first motor fixedly installed on the other side surface of the vertical plate, the output shaft of the first motor fixedly connected to one of the two rotating rods, a synchronous wheel fixedly installed on the surface of each of the two rotating rods, and a conveyor belt sleeved on the surface of the two synchronous wheels.

[0009] The spacing adjustment mechanism includes an adjustment groove on the upper surface of the base. A second motor is fixedly installed on the right side surface of the base. The output shaft of the second motor extends into the interior of the adjustment groove and is fixedly connected to a bidirectional threaded rod. Two symmetrical threaded blocks are threadedly connected to the surface of the bidirectional threaded rod. The upper surfaces of the two threaded blocks are fixedly connected to the lower surfaces of the two vertical plates, respectively.

[0010] Preferably, two symmetrical guide sliders are fixedly installed on the lower surfaces of the two vertical plates, and a guide groove is provided on the upper surface of the base for the guide sliders to slide.

[0011] By adopting the above technical solution, under the guidance of the guide slider, the two threaded blocks can drive the two vertical plates to move closer together or in opposite directions through the rotation of the bidirectional threaded rod.

[0012] Preferably, the transfer mechanism includes a storage groove formed on the lower surface of the base, a screw rotatably connected to the inner top wall of the storage groove, a rotating opening extending through the storage groove on the left side surface of the base, a crank handle rotatably connected to the inner wall of the rotating opening, a bevel gear fixedly connected to the right end of the crank handle extending into the storage groove and the surface of the screw, a base plate threadedly connected to the surface of the screw, and four universal wheels arranged in a rectangular array installed on the lower surface of the base plate.

[0013] Preferably, the two bevel gears mesh with each other, and the crank handle is connected to the screw drive via the bevel gears.

[0014] Preferably, the base plate is provided with limit sliders on both the front and back sides, and the inner front wall and inner rear wall of the storage groove are provided with limit grooves for the limit sliders to slide.

[0015] By adopting the above technical solution, under the guidance of the limiting slider, the base plate can drive the universal wheel to move up and down in a directional manner through the rotation of the screw.

[0016] Preferably, the lower surface of the base plate is provided with a reinforcing edging, and the lower surface of the reinforcing edging is provided with an anti-slip pad.

[0017] By adopting the above technical solutions, the reinforcement of the edging and the installation of anti-slip pads make the base more stable when mounted on the ground.

[0018] Preferably, protective baffles are provided on both sides of the conveyor belt. The protective baffles are connected to the vertical plate by hinges and the opening and closing angle of the protective baffles can be adjusted as needed to prevent the cardboard from slipping out during transportation.

[0019] Preferably, the first motor is connected to the rotating rod through a reduction gear. The reduction gear can convert the rotation speed of the first motor into a low-speed operation suitable for cardboard transportation, thereby improving the stability and accuracy of the system.

[0020] Preferably, the storage slot is also equipped with an automatic locking device, which can automatically lock the position of the screw after the crank operation is completed, preventing the screw from rotating unexpectedly during transportation and ensuring the stability of the caster wheels.

[0021] Preferably, the surface of the anti-slip rubber pad is made of wear-resistant material, which can effectively reduce friction when the base plate contacts the ground, extend service life, and improve the stability and durability of the cardboard conveyor.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Place the cardboard to be conveyed on two conveyor belts. The operation of the first motor drives the conveyor belt through the rotating rod to convey the cardboard. During this process, the operation of the second motor drives the bidirectional threaded rod to rotate. Under the rotation of the bidirectional threaded rod, the two threaded blocks drive the two vertical plates to move closer or in opposite directions. The feeding distance between the two vertical plates can be adjusted according to the width of the cardboard, avoiding displacement or skew during the conveying of narrow cardboard, thus improving the adaptability of the conveying device.

[0024] 2. When it is necessary to move or adjust the installation position of the device, turn the crank to drive the screw to rotate through the bevel gear. Under the guidance of the limit slider, the base plate can be moved down by the rotation of the screw to drive the casters until the casters contact the ground and lift the base. At this time, the device can be moved by the casters without the need for manual lifting, which provides convenience for its transportation. Attached Figure Description
