Description

TECHNICAL FIELD

[0001] The present application belongs to the field of wood door lock hole machine equipment, and particularly relates to a continuous working through type double-channel lock hole machine. BACKGROUND

[0002] The double-channel wood door lock hole machine is a kind of machine specially used for processing wood door, fireproof door and wood window lock hole groove, and can process door lock hole (vertical drilling + milling lock hole shape) on one side and synchronously process hinge groove (horizontal milling hinge installation position) on the other side, thereby greatly improving the processing efficiency. The double-channel lock hole machine mainly comprises a main shaft processing system located on both sides of a base, a belt conveying mechanism, a positioning and clamping device and an auxiliary dust collection system, wherein the belt conveying mechanism adopts a double-belt design and can be adjusted in lifting, and conveys the wood door to the processing position and then lowers to avoid. After the belt lowers, the mechanical clamping device fixes the wood door, so as to ensure the processing stability. When continuously processing the door lock groove, the hinge groove and the door closer silent groove (especially the upper and lower end groove positions of the door body), a large amount of wood chips will be generated, and these chips are easy to fall on the surface of the belt. When the belt rises and resets after the wood door processing is completed, the wood chips will be clamped between the belt and the board, so as to change the friction coefficient of the contact surface. The friction force generated between the double-belt and the board is different due to the uneven distribution of the wood chips, so that the board is unevenly stressed during conveying, and the board is deflected during the conveying process, thereby affecting the subsequent processing and positioning accuracy. The uncleaned wood chips may continuously adhere to the surface of the belt, so as to scratch the paint surface or cause groove size error during processing. The wood chips intervene and destroy the stable friction state of the conveying system, so as to cause the imbalance of the cooperative action of the double-belt, and finally affect the conveying stability and processing quality consistency of the board. Therefore, it can be seen that the prior art needs to be further improved and improved. CONTENT OF THE UTILITY MODEL

As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present application. Therefore, the drawings and the description are considered to be essentially exemplary rather than limiting.

[0024] In the description of the utility model, it needs to understand that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like is the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

However, it is noted that direct connection means that the connection between the two main bodies does not form a connection relationship through excessive structure, but is connected to form a whole only through the connecting structure. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0026] In the utility model, the description of "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features.

[0027] The utility model will be described below in conjunction with the drawings of the specification.

[0028] The specific scheme adopted is:

[0029] For example Figures 1-3The utility model provides a kind of continuous working through type double channel lock hole machine, including bed 1 and the first processing module 2 and the second processing module 3 with different functions located at the both sides of bed, two groups of conveying positioning module are equipped on the upper side of bed, conveying positioning module includes support table 10 and the belt conveying mechanism 12 and clamping mechanism 13 respectively located in its inside and outside, belt conveying mechanism can be lifted relative to support table, dust cleaning system is integrated inside support table, air hole is equipped on the side of support table towards belt conveying mechanism, in the process of processing wooden door, air hole 101 blows airflow to the surface of belt, to blow the sawdust on the surface of belt, to ensure the stable friction conveying state of belt conveying mechanism.

[0030] The continuous working through type double channel lock hole machine of the application can effectively blow the sawdust on the surface of belt by integrating dust cleaning system inside support table and setting air hole to blow obliquely downward airflow to the surface of belt. The sawdust is prevented from being squeezed between belt and board, so as to maintain the stable friction conveying state of belt conveying mechanism. Since the sawdust is cleaned in time, the friction between belt and board remains uniform, avoiding the problems of uneven force and deflection of board during conveying caused by uneven distribution of sawdust. This helps to improve the precision and stability of processing. Cleaning the sawdust falling on the conveying belt can also reduce the scratches of wooden door paint surface caused by sawdust, thereby improving the consistency of processing quality and product qualification rate. By maintaining the stable friction conveying state of belt conveying mechanism, the continuity and stability of processing process can be ensured, thereby improving production efficiency.

[0031] As a preferred embodiment of the application, the dust cleaning system includes an air inlet channel 100 opened along the length direction of support table, and the air holes are arranged in multiple and communicated with the air inlet channel along the length direction of support table, and the air inlet channel is communicated with a blowing device.

[0032] The air inlet channel is opened along the length direction of support table, but does not penetrate through the entire support table, and can be made of PVC material. This material has good corrosion resistance and wear resistance, and is relatively light in weight, facilitating processing and installation. The air holes are arranged in multiple along the length direction of support table, and each air hole 101 is communicated with the air inlet channel 100. The communication channel between the outlet of air hole and the air inlet channel is inclined, which can make the airflow have a certain obliquely downward angle when blown out, so as to better blow the sawdust on the surface of belt. The air inlet channel is communicated with the blowing device, which provides power for the entire dust cleaning system. The blowing device can adjust the strength and frequency of airflow as needed to meet the cleaning needs under different processing conditions.

[0033] Further, the blowing device is electrically connected to the processing module control system. When the processing module is working, the blowing device starts to work, for example, continuously or intermittently. When the blowing device starts, the airflow enters the inside of the support table 10 through the air inlet channel, and flows along the inclined communication channel to the air hole. Since the communication channel between the air hole outlet and the air inlet channel is inclined, the airflow has a certain downward angle when it is blown out. When the airflow is blown out of the air hole, it will directly act on the surface of the belt, blowing away the wood chips. Since multiple air holes are arranged along the length direction of the support table, the entire surface of the belt can be evenly cleaned.

[0034] Referring to Figure 3 , the support table is arranged on the upper side of the profile bracket, the rack 120 of the belt conveying mechanism is connected to the first L bracket 110, the inner side of the profile bracket 11 is connected to the second L bracket 111, the second L bracket is connected to the lifting cylinder 14, and the piston rod of the lifting cylinder passes through the second L bracket to connect the first L bracket.

[0035] When the height of the belt conveying mechanism needs to be adjusted, the piston rod will drive the first L bracket and the rack of the belt conveying mechanism connected thereto to move up and down by controlling the extension and retraction of the lifting cylinder. Since the second L bracket serves as the fixed point of the lifting cylinder and is connected to the profile bracket, the stability and accuracy of the lifting process are ensured. In this way, the belt conveying mechanism can be lowered below the support table when needed, so that the processed materials can smoothly enter the processing area; after the processing is completed, the belt conveying mechanism can be raised to an appropriate position to convey the processed materials. The entire lifting mechanism is compact in design and occupies a small space, which is conducive to the overall layout and installation of the equipment.

[0036] As a preferred embodiment of the present application, referring to Figure 1 and Figure 2 , the clamping mechanism includes a pressing cylinder 130 arranged on the other side of the profile bracket, and the piston rod of the pressing cylinder is connected to a pressing plate 131, which can be lifted to approach or move away from the support table.

[0037] When processing the side locking hole and other parts of the wooden door, the local thinning of the plate may cause damage to the plate when a vacuum suction disc is used. However, the use of a pressing cylinder can effectively avoid this problem. When the material needs to be clamped, the piston rod of the pressing cylinder is extended to drive the pressing plate to descend and approach the support table, thereby exerting a stable clamping force on the material. This clamping method not only ensures the stability of the material during processing, but also avoids unnecessary damage to the material.

[0038] Referring to Figure 1 , the other side of the profile bracket is also provided with a side pushing cylinder 15, and the piston rod of the side pushing cylinder is connected to a side pushing piece, which pushes the plate to achieve deviation correction.

[0039] Referring to Figure 3 A positioning cylinder is arranged on the front side of the profile support, and the end of the plate abuts against the piston rod of the positioning cylinder to achieve positioning of the end of the plate.

[0040] Further, one side of the bed body is provided with a vertical beam capable of moving relative to the direction of the bed body, the vertical beam is connected with a cross beam, the cross beam is provided with a front pushing cylinder, the front pushing cylinder is connected with a lifting mechanism, the piston rod of the front pushing cylinder is connected with a front pushing piece, and the front pushing piece abuts against one end of the plate to push the plate to the other end to abut against the piston rod of the positioning cylinder.

[0041] Specifically, the plate is conveyed to the working area of the system by the belt conveying mechanism, when the plate is conveyed to a position close to the positioning cylinder, the front pushing cylinder is started, the piston rod thereof is extended and pushes one end of the plate. At this time, the lifting mechanism has been adjusted according to the thickness of the plate to ensure that the front pushing piece can accurately contact and push the plate. Under the pushing of the front pushing cylinder, the plate gradually moves to the end thereof to abut against the piston rod of the positioning cylinder. When the end of the plate contacts the piston rod of the positioning cylinder, the piston rod of the positioning cylinder remains in the extended state, thereby fixing the position of the end of the plate. At this time, the end of the plate has been accurately positioned. After the end of the plate is positioned, the side pushing cylinder is started, the piston rod thereof is extended and pushes the side pushing piece. The side pushing piece pushes the plate to the clamping mechanism on one side. The pressing cylinder of the clamping mechanism is started, the piston rod thereof is further extended and pushes the pressing plate to descend. The pressing plate contacts the plate and applies sufficient clamping force, thereby ensuring that the plate remains stable during the machining process. After the plate is clamped, subsequent machining operations such as punching and milling can be performed.

[0042] Through the cooperation of the front pushing cylinder 18, the positioning cylinder 17 and the side pushing cylinder, accurate conveying, end positioning and side positioning of the plate are achieved.

[0043] As a preferred embodiment of the present application, the bottom of the profile support is provided with a sliding block, the bed body is provided with a sliding rail 19, the sliding block and the sliding rail are connected in cooperation, the profile support is connected with a moving piece, the moving piece can move linearly along the lead screw, the lead screw is connected with a servo motor, and the action of the servo motor can drive the moving piece to move and drive the profile support to move.

[0044] Further, one of the two groups of profile supports is a fixed support, and the other is a moving support, the moving support is close to or away from the fixed support to adapt to plates of different widths.

[0045] When processing plates of different widths, the servo motor is started and drives the screw rod to rotate. Due to the threaded cooperation between the screw rod 16 and the moving piece, the moving piece moves linearly along the screw rod. The movement of the moving piece drives the profile bracket (i.e. the moving bracket) connected thereto to move along the slide rail. When it is necessary to adjust the distance between the two profile brackets, it can be achieved by controlling the action of the servo motor. One of the profile brackets (the fixed bracket) remains stationary, and the other profile bracket (the moving bracket) moves accordingly according to the width of the plate.

[0046] The parts not described in the utility model can be realized by using or referring to the existing technology.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any person skilled in the art can easily think of various changes or replacements within the technical range disclosed by the utility model, and these should be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
