Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery, in particular to a multi-line lower line wheel structure. Background Art

[0002] A carton forming machine is a processing equipment for packaging cartons. When processing cartons, it will press the surface of the carton through a wire wheel, so that the surface of the carton will have an indentation. The carton can be folded into a formed packaging box according to the indentation. When the forming machine presses the carton, it generally requires the lower wire wheel and the upper wire wheel to cooperate to press the carton. The carton passes between the upper and lower wire wheels, and the upper and lower wire wheels will produce indentations on the surface of the carton. Depending on the thickness of the carton, the indentations pressed by the wire wheel are different. Different indentations require lower wire wheels of different structures for pressing. Some indentations require the surface of the lower wire wheel to be a smooth plane, while some require a flat surface. Indentation requires a groove on the surface of the lower line wheel, and the width of the groove varies according to the thickness of the carton. In order to meet the requirements of different indentations, a rotatable triangular turntable is provided on the existing forming machine. The turntable has three lower pressing wheels at its three end corners. According to the thickness of the carton, the turntable is controlled to rotate to replace the lower pressing wheels to meet different production needs. Although this setting can effectively adapt to production work with different line-indentation requirements, driving multiple lower line wheels for position adjustment through the turntable not only increases the space occupancy rate of components in the forming machine, but also the cost of this structure is higher, which greatly increases the production cost.

[0022] A mounting plate 3 is provided on one side of the upper end of the lower slide seat 1 , and the lower line wheel 2 is mounted on one side of the mounting plate 3 . A through shaft 4 is also provided in the frame, and the through shaft 4 passes through the lower line wheel 2 and the mounting plate 3 .

[0023] An adjusting screw 5 is also horizontally arranged in the frame. The adjusting screw 5 passes through the lower sliding seat 1 and drives the lower sliding seat 2 to move left and right in the frame. The adjusting screw 5 is driven to rotate by the motor in the frame.

[0024] Guide rods 6 are also provided in the frame at positions corresponding to both sides of the adjusting screw 5. The guide rods 6 also penetrate the lower sliding seat 1. The guide rods 6 enable the lower sliding seat 1 to perform linear motion in the lateral direction of the frame.

[0025] A cleaning brush 7 is also provided on the top of the lower sliding seat 1 , and the cleaning brush 7 contacts the lower end of the lower wire wheel 2 , and the cleaning brush 7 is fixed on the lower sliding seat 1 through a quick locking pin 8 .

[0026] The cleaning brush 7 includes a handle seat 7a and bristles 7b arranged on the top of the handle seat 7a. The bristles 7b are vertically upward and contact the lower end of the lower line wheel 2. A slot is also arranged on the top of the lower sliding seat 1. The handle seat 7a is inserted into the slot. The quick locking pin 8 penetrates the lower sliding seat 1 and the handle seat 7a at the same time.

[0027] When the lower line wheel 2 continuously completes the carton grooving work, some cartons will drop paper scraps at the indentation due to quality problems. These paper scraps stick to the surface of the lower line wheel 2. If they are not processed, it will affect the subsequent pressing work of the equipment, resulting in uneven indentations on the surface of the carton, and sometimes the paper scraps will be pressed into the grooves of subsequent cartons. The cleaning brush 7 can keep the lower line wheel 2 clean, so as to prevent various debris from remaining on the surface of the lower line wheel 2. The cleaning brush 7 can be quickly disassembled and assembled, which is also convenient for the staff to replace it in time, and the operation is convenient and quick.

[0029] A hollow mounting seat 10 is also provided on the lower sliding seat 1 at one end close to the rod head 8b, the pin rod 8a passes through the mounting seat 10, one end of the telescopic spring 8c rests on one side of the rod head 8b, and the other end of the telescopic spring 8c rests on the mounting seat 10. When the pin rod 8a is pulled out from the lower sliding seat 1, the mounting seat 10 can be used to dock the pulled out pin rod 8a so that it cannot be separated from the lower sliding seat 1, thereby preventing the quick locking pin 8 from falling off, and the end of the pin rod 8a with the block 8d can be docked inside the mounting seat 10.

[0030] The quick lock pin 8 makes the disassembly and assembly of the cleaning brush 7 more convenient, and its disassembly and assembly can be completed manually without the aid of tools. During installation, the handle seat is first inserted into the slot on the top of the lower sliding seat 1. After insertion, the block 8d at the end of the pin rod 8a is aligned with the movable slot 9 and the pin rod 8a is inserted into the lower sliding seat 1 and the brush handle 7a. When the pin rod 8a extends out of the other side of the lower sliding seat 1, the rod head 8b and the mounting seat 10 cooperate to squeeze the telescopic spring 8c to extend the block 8d in the lower sliding seat 1, and then the pin rod 8a is rotated to control the block 8d at its end to correspond to the slot 1a on the lower sliding seat 1, and then the pin rod 8a is released. Under the action of the restoring elastic force of the telescopic spring 8c, the block 8d will be inserted into the slot 1a. At this time, the pin rod 8a cannot be rotated and cannot be pulled out, thereby completing the installation of the cleaning brush 7. The whole process does not require the aid of tools, and the operation is convenient and quick.
