Description

Engraving and milling machine

Technical Field

The invention belongs to the technical field of engraving and milling equipment, and relates to an engraving and milling machine.

Background

The engraving and milling machine is a device for engraving and processing workpieces such as wood, stone and the like in a numerical control mode, has higher processing efficiency and processing precision compared with manual engraving, is widely applied, even replaces a manual engraving technology, and lays a foundation for the mass rapid production of products.

For example, the four-process wood carving machine disclosed in the Chinese patent document (application No. CN 201820600481.3; publication No. CN208682483U) comprises a supporting seat, a conveying belt, a processing table, a first clamping plate, a second clamping plate, a carving knife, a first electric push rod, a supporting plate and other components, wherein baffles are symmetrically arranged on two sides of the processing table. This engraver is through setting up the conveyer belt, when adding man-hour, the distance of two baffles about earlier adjusting is the same with timber length, adjusts the back and locks through spacing knob, then timber is along placing on the conveyer belt, and timber is carried to the carving tool below back by the conveyer belt, and electric putter drives the layer board and rises and carries out the centre gripping with timber, later relies on first splint and, second splint to carry out the centre gripping to timber, relies on the carving tool to carve timber after the centre gripping is good. In this engraver, set up two baffles, its effect is according to the length of different timber, changes the interval between two baffles for the workman can keep timber in the horizontality fast when placing timber, can not incline around making timber, can not incline from top to bottom.

The engraving machine has some defects in the engraving process: firstly, this engraver adopts the mode of transversely placing timber to carry out the transport of timber, and when timber removed to the processing platform bottom, the conveyer belt stop motion made the layer board upwards remove the back through the support groove on the layer board with timber jack-up. However, in the moment of stopping the conveyor belt, the wood is difficult to stop due to the existence of the initial speed, and workpieces of different materials or sizes have different masses and different inertias, so that the workpieces are easy to move forward and have different moving distances in the moment of stopping the conveyor belt, and thus after the conveyor belt is stopped, the workpieces are difficult to be aligned with brackets on the supporting plate, even the workpieces are inclined, so that the supporting plate cannot jack the workpieces stably or even cannot jack the workpieces, and the automatic feeding fails. In addition, this engraver is equipped with two brackets on every layer board, though can jack up two timber at every turn and process two timber simultaneously, can promote the efficiency of processing. However, the distance between the two brackets on the pallet is constant, so that when the pallet simultaneously jacks up two timbers, the distance between the two timbers on the conveyor belt is required to be equal to the distance between the two brackets. However, when wood is manually placed on the conveyor belt by workers, the mode is difficult to ensure that every two adjacent woods on the conveyor belt are equally spaced and equal to the distance between two brackets, so that the phenomenon that the supporting plate jacks up the woods easily occurs. Therefore, the structure of the engraving machine causes that the stability and the reliability of the automatic feeding process are low, and the requirement of automatic feeding of workpieces is difficult to meet in practice.

At present, the following technical means are mainly adopted by those skilled in the art to solve the above problems:

1. A carrier for positioning the wood is arranged on the conveyor belt. On the automated production equipment, it is a very common technical means to arrange a carrier on a conveyor belt to position a workpiece. After the carrier is arranged on the conveying belt, the carrier fixes the position of the workpiece relative to the conveying belt, so that after the conveying belt stops, the position precision of the workpiece can be ensured, the workpiece is enabled to be over against a bracket of a supporting plate, and the supporting plate can stably jack up the workpiece each time;

2. The supporting plate with adjustable supporting position is adopted. When the stop position of the timber and the supporting position of the supporting plate deviate, the supporting position of the supporting plate is adjusted, so that the supporting plate can stably support the timber at every time.

3. Adopts a conveying mode that the wood is attached side by side. All woods set up side by side on the conveyer belt and paste each other and lean on, can solve the problem that the slope appears in the timber transfer in-process.

Disclosure of Invention

The invention aims to solve the problems in the prior art, and provides a carving and milling machine.

The purpose of the invention can be realized by the following technical scheme: the engraving and milling machine is characterized in that a first material guide part and a second material guide part are arranged on the rack, a long and narrow material guide channel positioned at the upper part of the conveying assembly is formed between the first material guide part and the second material guide part, the material guide channel extends along the conveying direction of the conveying assembly, and a driving structure capable of driving the first material guide part and/or the second material guide part to horizontally reciprocate and translate along the conveying direction perpendicular to the conveying assembly is further arranged on the rack.

Of course, the driving source four 20 and the driving source three 24 may be a hydraulic cylinder, a rack and pinion mechanism, a motor screw mechanism, or the like.

The following briefly introduces the working principle of the engraving and milling machine: the engraving and milling machine is mainly used for processing bar-shaped workpieces, when processing is carried out, the workpieces are placed in the material guide channel 5 firstly, the length direction of the workpieces is enabled to be consistent with the length direction of the material guide channel 5, the workpieces are conveyed forwards under the action of the conveying assembly, when the workpieces reach the upper part of the material moving part 2 through the input port of the workpieces, the front ends of the workpieces are blocked by the front backer 7, and the workpieces stop. Then, the driving structure drives the first material guiding part 3 and the second material guiding part 4 to move towards the direction far away from the workpiece, so that the distance between the first material guiding part 3 and the second material guiding part 4 is increased, and the material moving part 2 is avoided. Then, the material moving part 2 moves upwards and clamps the workpiece in the feeding channel, after clamping is completed, the material moving part 2 continues to drive the workpiece to move upwards until the end faces of the two ends of the workpiece are respectively opposite to the tip 17 and the rotating disc 23 in the same axial direction, and the workpiece is clamped by the mutual approach of the tip 17 and the rotating disc 23. And finally, processing the workpiece by virtue of the engraving component 19 of the engraving and milling machine, simultaneously returning and resetting the material guide part 2 downwards, and resetting the first material guide part 3 and the second material guide part 4 under the action of the driving structure after the material guide part 2 retracts to finish a feeding process. And after the workpiece is machined, starting to perform blanking on the workpiece. During the blanking process of the workpiece, the workpiece can be transferred downwards to the conveying assembly from the space between the tip 17 and the turntable 23 through the material transferring part 2, and of course, the workpiece can also be released through the tip 17 and the turntable 23 and directly falls onto the conveying assembly. After the workpiece is fed onto the conveying assembly, the conveying assembly drives the workpiece to be output from the output port of the workpiece.
