Description

Technical Field

[0001] The utility model relates to a grooving planing mechanism. Background Art

[0002] As a learning tool, a pencil plays an important role in life. With the continuous development of society, the manufacturing process of pencils is also constantly improving. Among them, a pencil grooving machine is a device for grooving the lead core of the raw material plates for making pencils. The existing pencil grooving machine uses a rubber roller to drive the plates on the conveyor belt, so that the plates on the conveyor belt enter the grooving knife to achieve the purpose of conveying the plates for grooving. However, during the conveying process, due to the relatively fixed height of the traditional pressing plate structure, there are some plates that are relatively thick but still within the deviation range and cannot pass through the conveying and subsequent processing smoothly. Especially in the first processing process of a three-knife shaft grooving machine, if the height limit is too strict, the screening rate of the plates will be too high, which is not convenient for subsequent plate processing and will cause waste.

[0003] To solve the above problems, the utility model proposes a grooving planing mechanism that can dynamically adjust the passing of plates within a specific range. Summary of the Utility Model

Among them, the three-knife shaft fixed main board 401 and the three-knife shaft wire knife adjusting seat 402 are vertically arranged and connected by an L-shaped three-knife shaft support connecting plate. In order to realize the movement adjustment of the three-knife shaft fixed main board 401, the three-knife shaft wire knife adjusting seat 402 is connected to a three-knife shaft wire knife adjusting seat rotating shaft 416 and adjusts the lifting through the three-knife shaft wire knife adjusting seat rotating shaft 416. The three-knife shaft wire knife adjusting seat rotating shaft 416 is installed on the three-knife shaft support connecting plate;

[0031] The middle part of the three-knife shaft wire knife adjusting seat 402 horizontally passes through a wire knife shaft assembly 418. A wire knife 403 is provided at the front end of the wire knife shaft assembly 418. An elastic clamping assembly is arranged above the wire knife 403. The elastic clamping assembly is installed on the three-knife shaft wire knife adjusting seat 402. The elastic clamping assembly adjusts the pressing force on the conveyed sheet by elastic pressing, facilitating the wire knife 403 to cut the bottom of the sheet.

The fixed end of the wire knife shaft assembly adjusting rotating shaft 417 is installed on the top of the three-knife shaft fixed main board 401;

[0032] In order to effectively realize the assembly of the elastic clamping assembly, a three-knife shaft pen channel board seat 404 is hinged to the front end of the three-knife shaft fixed main board 401 and can realize flip maintenance. An aluminum alloy handle is provided at the front end of the second layer step of the three-knife shaft pen channel board seat 404 for easy flipping;

[0033] See Figure 1 . The elastic clamping assembly is installed on the three-knife shaft pen channel board seat 404. Specifically, the elastic clamping assembly includes a three-knife shaft pressing plate fixing plate 405 fixedly installed on the first layer step of the three-knife shaft pen channel board seat 404. Lower knife shaft pressing pen adjusting screws 411 are installed on the left and right sides of the three-knife shaft pressing plate fixing plate 405. The lower knife shaft pressing pen adjusting screws 411 are double-headed threaded screws with a smooth shaft in the middle. The lower part of the lower knife shaft pressing pen adjusting screw 411 is threadedly connected to a lower knife shaft pressing pen support plate 406, passes through the three-knife shaft pressing plate fixing plate 405 with interference in the middle, and a third compression spring 412 is sleeved on the upper part from top to bottom and locked by a second butterfly nut 413;

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-knife shaft 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 upwardly tilted pen feeding end knife shaft pressure plate 409. In order to achieve effective pressure feeding cooperation, the A three-axis upper support seat plate 407 is sandwiched between the knife shaft pressure plate 409 at the pen feeding end and the second step of the three-axis pen path plate seat 404. The three-axis upper support seat 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 seat plate 407 and the knife shaft pressure plate 409 at the pen feeding end. In order to facilitate the fixation of the three-axis pressure plate fixing plate 405, the first step surface area of the three-axis pen path plate seat 404 is smaller than the second step surface area of the three-axis pen path plate seat 404.

[0035] Working principle: Figures 1 - 2 , 4 and 5-6, this scheme is set on the first knife position of the three-axis planing machine, which is mainly used to press the plate delivered from the feeding end up and down, and by adjusting the lower pen-feeding end knife shaft pressure plate to move up, the size of the feeding channel between the pen-feeding end knife shaft pressure plate and the three-axis upper support base plate is controlled, and the plate is effectively pressed together to facilitate the wire knife set below to plane the plate, 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;

[0036] The specific method is: after assembling the parts according to the diagram, adjust the lifting height of the three-axis wire knife adjustment seat by adjusting the three-axis wire knife adjustment seat shaft on the L-shaped three-axis support connecting plate, thereby adjusting the height of the three-axis pen plate seat and the elastic clamping assembly installed on the three-axis wire knife adjustment seat, so as to better adapt to the wire knife shaft assembly. It should be noted that the wire knife shaft assembly adjusts the height of the shaft through the wire knife shaft assembly adjustment shaft on the three-axis fixing 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 1In the (directional position), a downwardly screwed lower cutter shaft pen pressing adjustment screw is provided. The three-cutter shaft pressing plate fixing plate is installed on the first step of the three-cutter shaft pen channel plate seat. The middle part of the lower cutter shaft pen pressing adjustment screw is a smooth shaft, and threads are respectively provided on both sides. The threads on both sides are respectively used to match the second wing nut above. A third compression spring is sleeved on the lower cutter shaft pen pressing adjustment screw between the second wing nut and the three-cutter shaft pressing plate fixing plate, which facilitates elastic adjustment of the lifting amplitude of the pen feeding end cutter shaft pressing plate. The bottom of the lower cutter shaft pen pressing adjustment screw is fixedly connected to the lower cutter shaft pen pressing support plate by threads. The lower cutter shaft pen pressing support plate is connected downward with a lower cutter shaft pen pressing fixing plate support shaft. It should be noted that the lower cutter shaft pen pressing fixing plate support shaft is also in the form of having threads on both sides and a smooth shaft in the middle. One side thread of the lower cutter shaft pen pressing fixing plate support shaft is screwed to the lower cutter shaft pen pressing support plate, the smooth shaft part passes through the limit hole of the second step of the three-cutter shaft pen channel plate seat and is limited by it, and the other side thread is fixedly connected to the lower cutter shaft flat pressing plate cross beam, so as to drive the pen feeding end cutter shaft pressing plate on the lower cutter shaft flat pressing plate cross beam to press the plate upward, so as to realize pressing on the plate. In order to better achieve the clamping effect, a three-cutter shaft upper support seat plate is also provided below the second step of the three-cutter shaft pen channel plate seat. During use, if it is necessary to limit and reduce the deviation (i.e., thickness range) of the fed plate, the second wing nut can be tightened downward to make the third compression spring in a more tense state, and then the downward space of the pen feeding end cutter shaft pressing plate is reduced; conversely, if it is necessary to limit and increase the deviation (i.e., thickness range) of the fed plate, the second wing nut can be loosened upward to make the third compression spring in a relaxed state, and then the downward space of the pen feeding end cutter shaft pressing plate becomes larger, so as to effectively realize the feeding and processing of plates with different thicknesses, facilitate implementation and control, and reduce problems such as jamming during plate feeding, discontinuous processing, and the need to remove plates with different thicknesses.
