Description
Technical Field
The invention belongs to the technical field of plate processing, relates to mechanical equipment for processing a chopping block, and particularly relates to processing equipment suitable for double-end groove milling of the chopping block.
Background
The chopping board is a daily necessity, and is divided into two types, namely a wood chopping board and a bamboo chopping board, from the material, and the plastic chopping board is relatively few in use. The shape of the chopping board is mainly square and round, wherein the waste materials are the least when the square chopping board is processed, and the processing process is simple and relatively common.
The natural thickness of bamboo timber is less than the general thickness of chopping block, and the bamboo chopping block is mostly two-layer or three-layer composite construction, and in the three-layer composite chopping block, because the intermediate level does not receive wearing and tearing and generally invisible, so to the requirement lower to material wear resistance, colour, texture etc. for practice thrift the cost, those colour or texture are not good unsuitable to be used for the material and corner waste material on top layer also can be used for the intermediate level. But the middle layer is visible on the side end face of the chopping block, and the color or texture of the middle layer is disordered or has the same influence on the whole appearance of the chopping block when the color difference with the bamboo color difference of the upper surface layer and the lower surface layer is obvious. In order to avoid the influence of the middle layer on the appearance of the chopping block, on one hand, when a long plate of the middle layer is processed, bamboo strips with color textures similar to those of the surface layer are selected as two side edges of the middle layer, on the other hand, after a single chopping block is obtained by cutting the long plate, a groove is milled along the middle layer on two end faces in the length direction, and then bamboo strips with color textures similar to those of the surface layer are attached to the groove to shield the middle layer.
At present, equipment special for milling grooves on the side edges of the chopping board is not provided, manual processing is mostly adopted for the milling grooves on the side edges of the chopping board, and a cutter is mainly driven by a motor to rotate at a high speed. An operator holds the chopping board by hand, and pushes and translates the chopping board to finish the groove milling after aligning one end of the chopping board needing the groove milling with the cutter. The manual groove milling mode is not only low in efficiency, and the working strength of operators is high, more importantly, the full-automatic line production of chopping board subsequent treatment cannot be realized, and the exertion of other automatic chopping board equipment is influenced.
Disclosure of Invention
The invention aims to provide a double-station double-end automatic groove milling scheme for a chopping board, aiming at solving the problem that double-end automatic groove milling of the chopping board is not realized in the prior art. The scheme is helpful for realizing the flowing automation of the whole process of the chopping board subsequent treatment.
Aiming at the purposes, the technical scheme provided by the invention is as follows: a cutting board double-end automatic slot milling machine comprises a rack, a feeding device and two slot milling mechanism assemblies, wherein the feeding device and the two slot milling mechanism assemblies are arranged on the rack;

And the chain conveying mechanism with the conveying mechanism and the matched tray is troublesome compared with a cylinder pushing mode, occupies a large area, and is not easy to realize the full-automatic production line of the chopping board. The invention preferably adopts a cylinder pushing mode to realize the longitudinal conveying of the chopping board.
The feeding mechanism comprises a feeding table top and a feeding cylinder, the feeding table top is flush with the workbench, a cylinder body of the feeding cylinder is relatively fixed with the rack, a pushing assembly is arranged on a piston rod and comprises a cylinder support connected with a piston rod of the feeding cylinder, the cylinder support is arranged in a front-and-back displacement mode relative to the rack through a linear slide rail mechanism, a first cylinder with a vertically upward piston rod is arranged below the cylinder support, and the highest extending position of the piston rod of the first cylinder is higher than the feeding table top and lower than the thickness of a chopping board; two gaps capable of accommodating the front and back displacement of the piston rod of the first cylinder are arranged on the feeding table surface; a blocking plate is arranged in front of the feeding table surface, and a chopping block can pass through a gap between the lower end of the blocking plate and the feeding table surface.
When the automatic feeding device works, a plurality of cutting boards for processing are stacked behind the upper blocking plate of the feeding table board, the first cylinder of the pushing assembly at the rear side of the stacked cutting boards acts, the piston rod of the first cylinder rises, and then the feeding cylinder acts to drive the feeding assembly to move forwards. A first cylinder piston rod pushes the cutting board at the lowest position in the stacked cutting boards to slide forwards on the feeding table board, and the cutting boards placed below the second cutting board and above the second cutting board are blocked by the blocking board and stop at the rear side of the blocking board.
When the chopping block is sent to the next station, the first air cylinder acts, the piston rod of the first air cylinder descends to the lower part of the workbench, and the feeding air cylinder acts reversely to drive the pushing assembly to return. The feeding of the chopping block can be automatically realized by repeating the steps.

The forward stroke of the movable positioning piece arranged on the first side of the chopping board is equal to the distance of the target positioning point of the stroke starting point. The forward stroke of the third positioning piece is greater than the distance of the target positioning point of the stroke starting point.
Furthermore, the first positioning piece is fixed with a piston rod of a first positioning cylinder, and a cylinder body of the first positioning cylinder is fixed relative to the horizontal workbench.
The second positioning piece is preferably a positioning block which is fixedly arranged relative to the horizontal station table. Of course, the second positioning element may also adopt the same arrangement structure as the first positioning element, that is, the second positioning element is fixed to the piston rod of a positioning cylinder, and the cylinder body of the positioning cylinder is fixed relative to the horizontal workbench.
The third positioning piece is fixed with a piston rod of the second positioning cylinder, and a cylinder body of the second positioning cylinder is fixed relative to the horizontal workbench.
As a modification, the piston sliding direction of the first positioning cylinder is arranged obliquely relative to the transverse direction; when the first positioning piece is at a low position, the positioning action surface of the first positioning piece is flush with the positioning action surface of the positioning block.
If the sliding directions of the piston rods of the first positioning cylinder and the second positioning cylinder are parallel to the transverse direction, the positioning pressure of the first positioning cylinder is required to be greater than or equal to the positioning pressure of the second positioning cylinder, and if the first positioning cylinder is pushed by the second positioning cylinder, the first positioning piece retreats and cannot realize positioning. By adopting the improved scheme of the inclined arrangement of the air cylinders, the air cylinders with smaller pressure than the second positioning air cylinder can be selected to realize positioning.
The third positioning piece can be arranged in various ways, and the chopping board can be positioned on the other side edge of the chopping board.
The clamping and conveying mechanism comprises two sets of clamping mechanisms which are respectively arranged corresponding to the front side and the rear side of the clamped chopping board, and each set of clamping mechanism comprises a clamping assembly and a clamping cylinder.
The clamping components of the two sets of clamping mechanisms are respectively arranged below a clamping component mounting plate in a longitudinally sliding manner.
The clamping assembly mounting plate can longitudinally slide back and forth relative to the rack through a longitudinal linear slide rail mechanism, and a longitudinal screw rod nut mechanism for driving the clamping assembly mounting plate to longitudinally slide relative to the rack is arranged between the clamping assembly mounting plate and the rack.
The centre gripping subassembly include clamping jaw, clamping jaw lift cylinder, the clamping jaw sets up the piston rod lower extreme at clamping jaw lift cylinder, clamping jaw lift cylinder body sets up for the slidable of centre gripping subassembly mounting panel, centre gripping cylinder body is connected with the clamping subassembly mounting panel, the piston rod is connected with clamping jaw lift cylinder body.
The working process of the clamping and conveying mechanism is as follows: aiming at the chopping block positioned at a transmission starting point, clamping jaw lifting cylinders in two sets of clamping components of a clamping and transmitting mechanism firstly act to enable two clamping jaws to respectively descend to the front and the rear of the front end and the rear end of the chopping block, then the two clamping cylinders act respectively to drive the two sets of clamping components to slide oppositely to drive the two clamping jaws to move oppositely to clamp the chopping block, and finally a longitudinal screw rod nut mechanism for driving a clamping component mounting plate to slide longitudinally relative to a rack drives the clamping component mounting plate to carry the clamping mechanism and the clamped chopping block to slide longitudinally forwards along a horizontal working table surface until a transmission end point. One side end surface of the chopping block passes through a cutter of the groove milling device in the sliding process to be processed into a groove which is through from front to back. After the chopping block is conveyed to the terminal point, the clamping cylinder acts firstly to drive the two clamping jaws to move back and forth to remove the clamping of the chopping block, then the clamping jaw lifting cylinder acts to lift the clamping jaw upwards, the clamping jaw needs to be lifted to the position where the lowest end of the clamping jaw is higher than the upper surface of the chopping block, and finally the longitudinal screw rod nut mechanism used for driving the clamping assembly mounting plate to slide longitudinally relative to the rack acts to drive the clamping assembly mounting plate to carry the clamping mechanism to return backwards to the conveying starting point.
As an improvement, in order to adapt to chopping blocks with different longitudinal width specifications, the longitudinal position of a clamping cylinder body of a set of clamping mechanism positioned in front relative to a clamping component mounting plate can be adjusted.
As a further improvement of the clamping and conveying mechanism, the clamping and conveying mechanism further comprises a flattening component, and the flattening component is used for flattening the chopping board under the action of the working table surface where the chopping board to be conveyed is located;

For example, the middle part or both ends of the chopping board may tilt upwards, and if the chopping board tilted at a certain position is not pressed flat in the groove milling process, the width from the groove milled on the end surface to the surface of the chopping board is not uniform. The chopping block is pressed to be flat through the flattening component in the process of milling the groove, and the quality of milling the groove on the end face of the chopping block is improved.
Furthermore, the first positioning cylinder and the clamping cylinder are sliding table cylinders. The work piece can directly be adorned on the slip table of slip table cylinder.
Furthermore, in order to realize the streamlined operation of the chopping board, a discharging and pushing component is also arranged in the second slot milling mechanism assembly. The discharging pushing component is fixedly arranged relative to a clamping jaw of the clamping component positioned in front.
The groove milling device comprises a motor, a main shaft mounting seat and a milling cutter, wherein a main shaft is arranged in the main shaft mounting seat, the main shaft mounting seat is fixedly mounted below the workbench, the motor is connected with the main shaft mounting seat, and the motor is connected with the lower end of the main shaft through a belt conveying mechanism; the milling cutter is arranged at the upper end of the main shaft, the milling cutter is of a circular sheet structure, a cutting edge is arranged on the circumference, and the width of the cutting edge is the target width of the milling groove.
When the automatic double-end cutting board slot milling machine is used for double-end slot milling of a cutting board, a plurality of cutting boards to be processed are stacked on the workbench at the position of the feeding mechanism, the feeding mechanism can feed the lowermost cutting board into the position of the positioning mechanism of the first slot milling mechanism assembly along the workbench by single action, and the position is just the transmission starting point of the cutting board of the first slot milling mechanism assembly in the processing process. And after the positioning of the mechanism to be positioned is completed, the first positioning piece and the third positioning piece are retreated. The clamping and conveying mechanism works to convey the chopping block from the conveying starting point to the conveying end point. At this point, the groove of one end face has been machined. The processing and conveying end point position of the first slot milling mechanism assembly is overlapped with the processing and conveying starting point position of the second slot milling mechanism assembly, namely the cutting board is positioned at the processing and conveying starting point position of the second slot milling mechanism assembly at the moment, the position is the position of the positioning mechanism of the second slot milling mechanism assembly, and the cutting board is sent out after the second slot milling mechanism assembly completes the positioning, conveying and processing of the slot on the end face on the other side. Thus realizing the automation of the double-end milling of the cutting board.
In the whole process, the feeding mechanism, the first slot milling mechanism assembly and the second slot milling mechanism assembly can work synchronously, namely when the second slot milling mechanism assembly processes the first chopping block, the first slot milling mechanism assembly processes the second chopping block at the same time, and meanwhile, the feeding mechanism sends the third chopping block to the transmission starting point of the first slot milling mechanism assembly. Namely, the double-end groove milling of one chopping block can be completed only by the time of groove milling of one end, and the efficiency is obviously improved. And two sets of groove milling mechanism assemblies are mutually connected, an additional conveying mechanism is not needed in the middle, and the structure is compact and simple.
The invention has the beneficial effects that:
1. the arrangement of the movable positioning points is adopted, so that the problem that when the edge of the chopping board is not straight, the front positioning points block the chopping board to move forwards is avoided;
2. the obliquely arranged first positioning cylinder enables the slot milling machine to be compact in structure, and meanwhile, the condition that the chopping board is horizontally displaced due to the fact that acting forces are mutually offset when the cylinders are horizontally arranged is avoided;
3. the cutting board conveying mechanism is combined with two functions of clamping and conveying the cutting board, so that high-precision linear motion of the cutting board in the conveying process is effectively guaranteed, the cutting board conveying and machining can be completed synchronously by matching with a cutter fixedly arranged on a cutting board moving path, an action driving mechanism does not need to be independently arranged for machining actions, and the machining precision is guaranteed;
4. two sets of groove milling mechanism assemblies are combined, groove milling at the two ends of the chopping block is completed at one time, and the efficiency is doubled.
