Description

Technical Field

[0001] The utility model relates to a three-shaft slotting machine. Background Art

[0002] As a kind of learning supplies, pencils play an important role in our daily life. With the continuous development of society, the manufacturing process of pencils is also constantly improving. Among them, the pencil grooving machine is a device that grooving the lead core of the raw material sheet of pencils. The existing pencil grooving machine uses a rubber roller to drive the sheet on the conveyor belt, so that the sheet on the conveyor belt enters the grooving knife to achieve the purpose of conveying the sheet for grooving. However, during the transmission process of the three-axis grooving machine, due to the relatively fixed height of the traditional pressure plate structure, some thicker sheets that are still within the deviation range cannot pass through the transmission and subsequent processing smoothly. Regardless of which station of the transmission, whether it is in the upper surface cutting or the lower surface cutting process, if the height limit of the sheet feeding is too rigid, the sheet screening rate will be too high, which is inconvenient for continuous processing of the sheet. In addition, it is also impossible to effectively achieve the effect of pressing the fed sheet.

DETAILED DESCRIPTION

[0055] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

Here, it should be noted that this solution is based on the original slotting machine foundation that has been applied for. Minor adjustments are made on the basis of the above, so other structural components, such as the saw blade trimming section, the propulsion assembly, the cleaning section, etc. have been disclosed in previously applied patents or can refer to existing equipment technology. The disclosed patents can refer to but are not limited to: "CN214394645U A kind of edge grooving machine, CN219705514U A kind of three-axis grooving machine, CN214686993U A kind of grooving propulsion wheel mechanism, CN202137811U A kind of grooving machine and the knife shaft adjustment device, grooving machine and planing rod machine", etc. The improvements and innovations made in this solution are described in detail as follows:

[0057] like Figure 4-10 In the first processing station (i.e., the first tool station) of the three-spindle slotting machine, the slotting and planing mechanism 400 includes a three-spindle fixed mainboard 401 installed on the frame, and a three-spindle wire knife adjustment seat 402 is installed on the front side of the three-spindle fixed mainboard 401. The middle part of the three-spindle wire knife adjustment seat 402 crosses the wire knife shaft assembly 418, and the front end of the wire knife shaft assembly 418 is provided with a wire knife 403. An elastic clamping component is provided above the wire knife 403, and the elastic clamping component is installed on the three-spindle wire knife adjustment seat 402. The elastic clamping component adjusts the pressing force on the conveyed plate by elastic pressing, so that the wire knife 403 can cut the bottom of the plate;

[0058] The middle part of the three-axis wire knife adjustment seat 402 crosses the wire knife shaft assembly 418, and the front end of the wire knife shaft assembly 418 is provided with a wire knife 403, and an elastic clamping component is provided above the wire knife 403, and the elastic clamping component is installed on the three-axis wire knife adjustment seat 402. The elastic clamping component adjusts the pressing force on the conveyed plate by elastic pressing, which facilitates the wire knife 403 to cut the bottom of the plate. In order to realize the movement of the wire knife shaft assembly 418, the wire knife shaft assembly 418 is connected to the wire knife shaft assembly adjustment shaft 417, and the lifting and lowering are adjusted by the wire knife shaft assembly adjustment shaft 417. The fixed end of the wire knife shaft assembly adjustment shaft 417 is installed on the top of the three-axis fixed main board 401;

[0059] In order to effectively assemble the elastic clamping assembly, the front end of the three-axis fixed main board 401 is hinged with a three-axis pen board seat 404, and can be flipped for maintenance. The front end of the second step of the three-axis pen board seat 404 is provided with an aluminum alloy handle for easy flipping;

[0060] The elastic clamping assembly is installed on the three-axis pen path board seat 404. Specifically, the elastic clamping assembly includes a three-axis pressure plate fixing plate 405 fixedly installed on the first step of the three-axis pen path board seat 404. Lower knife axis pen pressure adjustment screws 411 are installed on the left and right sides of the three-axis pressure plate fixing plate 405. The lower knife axis pen pressure adjustment screw 411 is a screw with double threads and an optical axis in the middle. The lower part of the lower knife axis pen pressure adjustment screw 411 is threadedly connected to the lower knife axis pen pressure support plate 406, the middle part is interference-connected to the three-axis pressure plate fixing plate 405, and the upper part is inserted into the third compression spring 412 from top to bottom and locked by the second butterfly nut 413;

[0061] The knife shaft pen pressure support plate 406 is fixedly mounted with a lower knife shaft pen pressure fixing plate support shaft 410. In order to achieve smooth and stable movement, the knife shaft pen pressure support plate 406 is symmetrically provided with at least an even number of lower knife shaft pen pressure fixing plate support shafts 410. The lower knife shaft pen pressure fixing plate support shaft 410 passes through the limiting hole of the second step of the three-axis pen path plate seat 404 and is fixed downward to the lower knife shaft flat pressure plate crossbeam 408. The lower knife shaft flat pressure plate crossbeam 408 is provided with an upward-tilted pen feeding end knife shaft pressure plate 409. In order to achieve effective pressure feeding cooperation, the A three-axis upper support base plate 407 is sandwiched between the pen feeding end blade shaft pressure plate 409 and the second step of the three-axis pen path plate seat 404. The three-axis upper support base plate 407 is fixedly installed at the bottom of the second step of the three-axis pen path plate seat 404. When the plate is fed in, it is fed in from the channel between the three-axis upper support base plate 407 and the pen feeding end blade shaft pressure plate 409. In order to facilitate the fixation of the three-axis pressure plate fixing plate 405, the first step table area of ​​the three-axis pen path plate seat 404 is smaller than the second step table area of ​​the three-axis pen path plate seat 404.

[0062] like Figure 11-15, in the second and third processing stations (i.e., the second tool position and the third tool position) of the three-axis slotting machine, the conveying sheet is pressed by the pressing plate mechanism 900 on both the first upper tool shaft cutting section 500 and the second upper tool shaft cutting section 600. The pressing plate mechanism 900 includes a front seat 902 of the pressing plate cross beam. The front seat 902 of the pressing plate cross beam is installed on the positioning plate 901. The positioning plate 901 is assembled on the machine frame. A rear seat 904 of the pressing plate cross beam parallel to the front seat 902 is provided behind the front seat 902 of the pressing plate cross beam. A pressing plate cross beam 905 that can be turned over and pressed downward is jointly connected between the front seat 902 of the pressing plate cross beam and the rear seat 904 of the pressing plate cross beam. At least two pressing plate cross beams 905 are symmetrically arranged. For a better pressing effect, see Figure 11 and 12 , a tool shaft pressing plate 906 is provided on one side of the pressing plate cross beam 905 facing the center. The tool shaft pressing plate 906 is locked at the bottom end of the pressing plate cross beam 905. The tool shaft pressing plate 906 is provided with a "冂"-shaped upward opening matching the bottom of the pressing plate cross beam 905. One side of the tool shaft pressing plate 906 facing the center is inclined. The pressing bottom surface of the tool shaft pressing plate 906 is horizontally arranged. The distance between the two tool shaft pressing plates 906 is not greater than the length of the conveying sheet. In this way, when the sheet is conveyed between the two tool shaft pressing plates 906, it can be effectively pressed by the tool shaft pressing plates 906 on both sides, facilitating the cutting of the surface layer of the sheet by the upper blade;

[0063] An elastic pressing member is assembled on each pressing plate cross beam 905. Specifically, the elastic pressing member includes a swinging rod 907 of the pressing plate cross beam fixedly connected above the pressing plate cross beam 905. The two swinging rods 907 of the pressing plate cross beam are alternately sleeved on the front seat 902 of the pressing plate cross beam. The other end of the swinging rod 907 of the pressing plate cross beam is movably connected to a movable pin 908 of the pressing plate cross beam. The movable pin 908 of the pressing plate cross beam is vertically inserted into the front seat 902 of the pressing plate cross beam and moves up and down along it. The lower half of the movable pin 908 of the pressing plate cross beam has an external thread. During assembly, a first compression spring 909 is sleeved on the movable pin 908 of the pressing plate cross beam from bottom to top and limited by a first butterfly nut 910 screwed from bottom to top. The other side of the first compression spring 909 abuts against the lower part of the front seat 902 of the pressing plate cross beam. As shown in the figure, in order to improve the utilization effect of space, the middle section of the swinging rod 907 of the pressing plate cross beam is provided with an arc transition;

[0064] In order to achieve the ability of the pressure plate crossbeam 905 to flip and move downward in conjunction with the elastic pressing member, we have made special restrictions on the position of the axis of the pressure plate crossbeam 905: the left and right sides of the pressure plate crossbeam front seat 902 are pressed into the pressure plate crossbeam adjustment block 903 and locked by bolts, the front end axis of the pressure plate crossbeam 905 is sleeved on the mounting hole of the beam adjustment block 903, the rear end axis of the pressure plate crossbeam 905 is sleeved in the movable groove of the pressure plate crossbeam tail seat 904, and a pressure plate adjustment column 911 is provided on the top of the movable groove, and the rear end axis of the pressure plate crossbeam 905 is abutted against the bottom of the pressure plate adjustment column 911, and the bottom of the pressure plate adjustment column 911 is pressed by the pressure plate The spring positioning column 912 is against the top, and the bottom of the pressure plate spring positioning column 912 is sleeved in the second compression spring 913, and the other side of the second compression spring 913 is limited on the frame. The pressure plate adjustment column 911 is always in contact with the limiting groove on the inner side of the pressure plate beam tail stock 904 during the movement. The limiting groove is vertically set in the pressure plate beam tail stock 904. This setting allows the pressure plate beam 905 to move slightly downward under the pull of the elastic lower pressure piece, thereby ensuring that the knife shaft pressure plate 906 is well pressed on the plate. In order to achieve effective support of the rear end axis, the pressure plate spring positioning column 912 is set in a "Y" shape or has an arc notch on the top.

[0065] Working principle: three-spindle slotting machine, first feed the plate into the feeding section, use the plate with the sawed end face to enter the saw blade trimming section as a reference, and use the three-propulsion wheel propulsion assembly to transport it to the slotting and planing mechanism (first knife position) based on the reference. The pen-end knife shaft pressure plate first presses the plate to the upper base, and at the same time uses the guide knife to plane out the surface finish and double guide wires. After planing, it is transported to the second knife position, and the processed surface is used as a reference to plane the upper surface and trim the overflow glue groove of the plate. After completion, it is transported to the third knife position, and the plate groove is planed and the two sides are trimmed at the same time. The wood chips on the plate are transported to the cleaning section to be cleaned, and the whole process of plate grooving is completed, and finally the plate is sent out from the discharging section. It should be noted that during the transportation process, a propulsion assembly is provided at intervals, and the propulsion assembly includes at least one propulsion wheel; in this solution, an elastic clamping assembly is provided in the grooving and planing mechanism, and an elastic pressing member is provided in the first upper cutter shaft cutting section and the second upper cutter shaft cutting section. By utilizing the elastic clamping assembly and the elastic pressing member, plates of a certain thickness range can pass through the three-spindle grooving machine smoothly, which is convenient for compacting, cutting and smooth transportation. Specifically:

[0066] In the first tool position, by controlling the size of the feeding channel between the pen-feeding end knife shaft pressure plate and the three-axis support base plate, the plate is effectively pressed together to facilitate the planing of the plate by the wire cutter set below, planing out the smoothness of the bottom surface of the plate and the double wires at the bottom; in this process, the adaptation effect is achieved by adjusting the pen-feeding end knife shaft pressure plate; after assembling the parts as shown in the figure, the lifting height of the three-axis wire cutter adjustment seat is adjusted by adjusting the three-axis wire cutter adjustment seat rotating shaft on the L-shaped three-axis support connecting plate, thereby adjusting the height of the three-axis wire cutter adjustment seat installed on the three-axis The height of the three-axis pen plate seat and the elastic clamping component on the axis wire knife adjustment seat is convenient for better adapting to the wire knife shaft assembly. It should be noted that the wire knife shaft assembly adjusts the height of the rotating shaft through the wire knife shaft assembly on the three-axis fixed main board, which is convenient for matching the whole machine. After the height adjustment of the two parts is completed, the lower knife shaft pen pressure adjustment screw of the three-axis pressure plate fixing plate on the three-axis pen plate seat is adjusted to elastically limit the conveying thickness of the conveying aisle. Specifically, the left and right sides of the three-axis pressure plate fixing plate ( Figure 1 The cam is fixed with the guide rail of the three-axis pen path plate, and the guide rail is fixed with the guide rail of the three-axis pen path plate. The cam is fixed with the guide rail of the three-axis pen path plate, and the guide rail is fixed with the guide rail of the three-axis pen path plate. The cam is fixed with the guide rail of the three-axis pen path plate, and the guide rail is fixed with the guide rail of the three-axis pen path plate. The screw thread on the other side is fixedly connected to the cross beam of the lower cutter shaft flat pressure plate, thereby driving the pen-feeding end cutter shaft pressure plate on the cross beam of the lower cutter shaft flat pressure plate to press the plate upward. In order to better achieve the clamping effect, a three-cutter shaft upper support seat plate is also provided under the second step of the three-cutter shaft pen path plate seat. During use, if it is necessary to reduce the deviation of the fed plate (that is, the thickness range) limit, the second butterfly nut can be tightened downward to make the third compression spring in a more tightened state, thereby reducing the descending space of the pen-feeding end cutter shaft pressure plate; conversely, if it is necessary to increase the deviation of the fed plate (that is, the thickness range) limit, the second butterfly nut can be loosened upward to make the third compression spring in a relaxed state, thereby increasing the descending space of the pen-feeding end cutter shaft pressure plate, thereby effectively realizing the feeding and processing of plates of different thicknesses, facilitating the implementation and regulation, reducing the problems of jamming and discontinuous processing when feeding plates, and the need to remove plates of different thicknesses;

[0067] The second and third tool positions are mainly used to press the plates from top to bottom, so that the plates within a certain deviation range can pass through the pressing plate mechanism and be planed with slots on the upper blade. The specific adjustment and adaptation method is: by adjusting the degree of tightening the first butterfly nut on the movable pin of the pressure plate crossbeam upward or downward, the tension of the first compression spring is adjusted. When the first butterfly nut is adjusted upward, the tension of the first compression spring becomes tighter, thereby reducing the downward swing amplitude of the elastic pressing member (specifically, the relevant connection part of the pressure plate crossbeam rocker in the figure). At this time, The controllable range of the plate that the knife shaft pressure plate enters is smaller, that is, the elastic buffer zone is smaller; when the first butterfly nut is adjusted downward, the tension of the first compression spring becomes loose, thereby making the elastic downward pressure member (specifically, the connection part related to the pressure plate beam rocker in the figure) move downward more, and the controllable range of the plate that can enter the knife shaft pressure plate is larger, that is, the elastic buffer zone is larger; at the same time, the rear end axis center of the corresponding matching pressure plate beam is also driven by the elastic downward pressure member, and the rear end axis center of the pressure plate beam is driven to tighten and press down in the movable groove, thereby finally making the knife shaft pressure plate and the plate better fit;

[0068] Through the effective coordination of the first, second and third tool positions with the plate, the plate jamming is reduced, making the entire processing smoother.

[0069] The present invention is described through preferred embodiments. Those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of this application are also within the scope of protection of the present invention.
