Description

Technical Field

[0001] The utility model relates to the technical field of carton processing, and particularly relates to a printing guiding mechanism. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models. In the production process of cartons, it is necessary to print the cardboard so that the required words and images are accurately printed on the cardboard. In the printing and production process of packaging cartons, the die-cut cardboard is subjected to graphic printing by a printing machine and then conveyed to the next processing step by a conveyor. Based on safety considerations and equipment maintenance needs, there is generally a safety distance or operating distance of dozens of centimeters between the printing machine and the conveyor to facilitate equipment maintenance operations.

[0003] Since the specifications and sizes of packaging cartons are diverse, cardboard with a larger size can be directly conveyed to the conveyor through the output roller of the printing machine after printing. However, when conveying smaller-sized cardboard, due to the gravitational force of the cardboard, the front end of the cardboard will fall through the gap between the printing machine and the conveyor, affecting production efficiency. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a printing guiding mechanism, which can not only guide smaller-sized cardboard during transmission, prevent the cardboard from falling through the gap between the printing machine and the conveyor, but also be easily disassembled for maintenance and replacement.

[0005] The technical solution adopted by the utility model to solve its technical problem is: a printing guiding mechanism, including a guiding part arranged on the conveyor. The guiding part includes a plurality of assembled installation parts and guiding plates detachably connected to each installation part. Each guiding plate extends from the same end of the conveyor, and rollers are arranged on the upper side of each guiding plate.

[0006] Explanation: The conveyor includes a frame and a conveyor belt arranged on the frame. An output roller is provided at the front end of the printing machine, and there is a gap between the output roller and the conveyor belt. The conveyor belt includes a plurality of belts arranged at intervals in the horizontal direction on the frame. The installation part is located below each belt, and the guiding plate is located in the gap between adjacent belts.

[0007] Compared with the prior art, the beneficial effects of the present solution are as follows: The guide plate is installed on the conveyor through the installation part and extends from one end thereof, located between the output roller of the printing press and the frame of the conveyor. The cardboard output from the output roller is guided through the guide plate and the rollers provided on the guide plate, so that it can be conveyed onto the conveyor belt of the conveyor and then sent to the next process, avoiding the smaller-sized cardboard from falling through the gap between the printing press and the conveyor during transportation, which affects the production efficiency; moreover, the installation part for installing the guide plate is spliced. When it is necessary to disassemble the guide part from the conveyor for repair or other processing, the installation parts can be separated one by one. Also, since the guide plate is detachably connected to each installation part, after separating the installation parts one by one, each guide plate can be respectively removed from the installation part, then the installation part can be moved away along the side of the conveyor belt, and the guide plate can be moved away above the conveyor belt. The structure is reasonable and convenient to operate.

[0008] As a preferred embodiment of the present utility model, the installation part includes a plurality of first installation rods and a second installation rod located between the two middle first installation rods. Connection holes and first connection columns that can match the connection holes are respectively provided at both ends of the first installation rod, and second connection columns for matching the connection holes are provided at both ends of the second installation rod.

[0009] The beneficial effects of the present solution: When splicing a plurality of first installation rods and the second installation rod and installing them on the frame, first place the first installation rod horizontally between the upper and lower sides of the conveyor belt. The first connection column at one end of the first installation rod is installed on the frame, and then the first connection column on the first installation rod at the second position is snapped into the connection hole on the above-mentioned first installation rod. Splice a plurality of first installation rods in sequence. After splicing half of the first installation rods, snap the second connection column provided at one end of the second installation rod into the connection hole on the first installation rod, and then snap the connection hole on another first installation rod with the second connection column provided at the other end of the second installation rod. Then splice the remaining first installation rods in sequence to complete the installation of the installation part and install it on the frame. The splicing is carried out by snapping the first connection column with the connection hole and the second connection column with the connection hole, which is convenient for disassembling the installation part from the frame, thus facilitating replacement and repair processing.

[0010] As a preferred embodiment of the present utility model, connection sleeves are detachably connected to each first installation rod and the second installation rod, and one side of each guide plate is connected to the connection sleeve.

[0011] Beneficial effects of this solution: The guide plate is detachably connected to the first mounting rod and the second mounting rod respectively through the connecting sleeve. When disassembling the mounting part, first rotate the connecting sleeve to rotate the horizontally arranged guide plate upward by a certain angle, and then disassemble the first mounting rod and the second mounting rod in sequence. After disassembling the first mounting rod and the second mounting rod, move the guide plate horizontally away from the first mounting rod and the second mounting rod respectively.

[0012] As a preferred embodiment of the present utility model, a plurality of rollers are arranged at intervals on each guide plate, and the plurality of rollers on each guide plate are symmetrically arranged in pairs.

[0013] Beneficial effects of this solution: A plurality of rollers are provided on the guide plate, which can make the cardboard conveyed from the output roller to the guide plate convey more smoothly, and the rollers on each guide plate are symmetrically arranged in pairs, which can prevent the cardboard from shifting during the conveying process on the guide plate.

[0014] As a preferred embodiment of the present utility model, chutes are provided on the frames on both sides of the conveyor, and each first connecting column can be slidably matched with the chute.

[0015] Beneficial effects of this solution: The mounting part is slidably matched with the frame through the first connecting column arranged on one side of the first mounting rod, and the distance between the guide plate and the output roller can be adjusted according to the specific size of the cardboard, and the applicable range is relatively wide.

[0016] As a preferred embodiment of the present utility model, a groove is provided on the circumferential surface of the first connecting column, a limiting part is provided on the side of the first connecting column away from the first mounting rod, the limiting part includes a hanging rope hung in the groove and a clamping block arranged at one end of the hanging rope, and the clamping block can be clamped with the chute.

[0017] Beneficial effects of this solution: After adjusting the distance between the guide plate and the output roller according to the specific size of the cardboard, the clamping block hung on the first connecting column is clamped into the chute on the frame, so as to limit the mounting part and prevent the mounting part from still sliding along the chute after adjusting the position.
