Description

Technical Field

[0001] The utility model belongs to the technical field of sheet processing, and particularly relates to an auxiliary bracket for cutting and reforming sheets. Background Art

[0002] Sheet reforming processing not only includes conventional operations such as cutting long sheets into short ones and wide sheets into narrow ones, but also includes sheet reforming processing for some special purposes, such as reforming triangular or fan-shaped plates for cable winding reels in a production line.

[0003] Taking the processing of triangular or fan-shaped plates as an example, the widths and sizes of raw wood sheets are different, so it is impossible to use a feeding mechanism at a specific angle for feeding; the traditional processing operation of triangular or fan-shaped plates usually uses a traditional table saw device and manual feeding. The whole processing process is manual feeding and control. Moreover, for the convenience of feeding, the cutting and reforming of special-shaped sheets is usually carried out in the order of smaller at the front and larger at the back. However, with the continuous improvement of safety production awareness, automated reforming equipment has gradually replaced traditional table saw devices. At present, for the reforming equipment on the market, for safety reasons, its saw blade is hidden inside the machine shell, and the operator cannot see the position where the saw blade cuts from the outside at all. This leads to the fact that this new safe reforming and cutting equipment cannot be applied to the automated reforming processing of such triangular or fan-shaped plates, making the reforming processing of triangular and fan-shaped plates only based on traditional table saws.

[0004] Therefore, we propose an auxiliary bracket for cutting and reforming sheets, so that the reforming processing of triangular or fan-shaped plates can achieve high-precision cutting processing on a new generation of reforming and cutting equipment. Content of the Utility Model

[0023] Embodiment:

[0024] In the current sheet metal reforming processing industry, due to the significant differences between the reforming processing operations of triangular or fan-shaped sheets and the conventional operations of shortening the length and narrowing the width, most of the existing automated sheet metal reforming processing equipment with safety processing as the primary goal currently on the market has the saw blade hidden inside the protective cover. When the operator feeds the material, it is impossible to know the cutting path of the sheet after it is conveyed by the conveyor belt into the equipment, or the cutting position and angle of the saw blade. As a result, this type of automated sheet metal cutting and reforming equipment is not suitable for the reforming processing of such triangular or fan-shaped sheets. Therefore, we propose an auxiliary bracket to help the operator use this type of automated sheet metal reforming equipment to process triangular and fan-shaped sheets. This not only enables the triangular or fan-shaped reforming processing of sheets to no longer be limited to traditional table saw operations, but also allows the operator to accurately know the subsequent cutting position and cutting path of the saw blade, which helps the operator timely adjust the cutting position and path according to the actual situation of the sheet, so as to improve the utilization rate of the sheet, reduce the number of secondary processing times and the waste of wood. The technical solution is as follows:

[0025] As Figures 1 - 3As shown in the figure, this embodiment provides an auxiliary bracket for cutting and reforming plates, which includes a lifting mechanism 1, an automatic return mechanism 2, a straightedge 3, and a one-line laser generator 4. The lifting mechanism 1 is installed on the front frame of the belt conveyor of the automatic plate reforming equipment. The automatic return mechanism 2 is horizontally installed on the side frame of the belt conveyor of the automatic plate reforming equipment, and the automatic return mechanism 2 is perpendicular to the lifting mechanism 1. Both ends of the straightedge 3 are rotatably connected to the end of the automatic return mechanism 2 and the end of the lifting mechanism 1 respectively. The one-line laser generator 4 is installed at the front end of the saw blade protective cover in the middle of the automatic plate reforming equipment. In order to facilitate the operator to know the saw blade cutting path and the knife-down position during feeding, so that the operator can adjust the feeding angle in time according to the actual situation of the wood, the one-line laser marking line emitted by the one-line laser generator 4 is parallel to the moving direction of the belt conveyor of the automatic plate reforming equipment, and the marking line projected by the one-line laser marking line emitted by the one-line laser generator 4 on the belt conveyor of the automatic plate reforming equipment is consistent with the position of the plate reforming saw blade of the automatic plate reforming equipment, that is, the projection position of the one-line laser marking line emitted by the one-line laser generator 4 is the position where the saw blade of the reforming equipment is located, and the marking line of the one-line laser on the wood board is the actual cutting path on the plate after the saw blade cooperates with the belt conveyor for feeding. The operator can easily know the subsequent knife-down position and cutting path of the saw blade before feeding, thus providing a reference basis and convenience for the operator to adjust the plate angle.

[0026] And in order to further facilitate the operator to adjust the feeding angle of the plate, as Figure 1 shown, the one-line laser marking line emitted by the one-line laser generator 4 is also on the same axis as the lifting mechanism 1. Moreover, the application of this auxiliary bracket makes the feeding of the plate be inclined placement angle feeding, so that the processing operation of changing a square plate into a triangular plate or a fan-shaped plate changes the traditional processing method with a smaller front and a larger back to the cutting and reforming sequence operation with a larger front and a smaller back, which is more conducive to the staff to flexibly plan the cutting path of the plate reforming according to the actual situation of the plate, thereby improving the utilization rate of the plate and avoiding waste of wood.

[0027] In order to make the feeding of the plate more labor-saving during the feeding process and also provide convenience for adjusting the feeding angle of the plate, as Figures 2 - 3 shown, the lifting mechanism 1 includes a first mounting plate 101 installed on the front frame of the belt conveyor of the automatic plate reforming equipment. A vertical slot 102 is fixed on the front surface of the first mounting plate 101. The top of the slot 102 is installed with a detachable lifting component through a pin shaft 104. The upper surface of the lifting component is flush with the working surface of the belt conveyor of the automatic plate reforming equipment or is designed at an inclined angle of 2-5 degrees.

[0028] For the sheet processing industry, in the sheet reprocessing, due to different product specifications, there are differences in the length, width, etc. of the original log sheets for reprocessing. Moreover, there are differences in the texture of each piece of wood, as well as the position of the original log from which the original log sheet is taken, which will result in differences in the actual situation of the square sheets of the same batch of log sizes. Therefore, when changing the square sheet into a triangular sheet or a fan-shaped sheet, auxiliary tools with fixed sizes or structures cannot be used. The auxiliary tool needs to be able to adapt to the reprocessing operations of various different types and sizes of square sheets. The lifting component in the lifting mechanism 1 should be designed as an adjustable structure, as follows:

[0029] As Figures 2 - 3 shown, the lifting component includes a main lifting arm 103 and a secondary lifting arm 106; the bottom of the front end of the main lifting arm 103 is fixed to the top of the pin shaft 104, and the secondary lifting arm 106 is slidably inserted inside the main lifting arm 103. A limiting groove 105 is provided on the surface of the main lifting arm 103, and a limiting block 107 that is slidably engaged with the limiting groove 105 is fixed to the surface of one end of the secondary lifting arm 106 close to the first mounting plate 101; a retaining block 108 is horizontally fixed to one end of the inner side of the limiting groove 105 away from the first mounting plate 101. The cooperation of the limiting groove 105, the limiting block 107, and the retaining block 108 mainly serves to prevent the secondary lifting arm 106 from disengaging from the main lifting arm 103; moreover, in order to enable the auxiliary support to accurately guide and lift sheets of different size specifications, a scale is engraved on the side of the secondary lifting arm 106; and a first fastening bolt 110 is threadedly assembled inside the main lifting arm 103 at one end away from the first mounting plate 101 and on the side opposite to the limiting groove 105 for positioning the extended length of the secondary lifting arm 106. It should be further noted that in order to allow the operator to accurately know the actual length of the lifting mechanism 1 during use, the length of the main lifting arm 103 can be designed to be any length between 50 - 80 cm according to requirements. In this way, the maximum extended distance of the cooperation between the main lifting arm 103 and the secondary lifting arm 106 can reach 90 - 150 cm.

[0030] To facilitate the detachable connection between the straightedge 3 and the lifting mechanism 1, as Figures 2 - 3 shown, a vertical shaft 109 for installing the straightedge 3 is fixed to one end of the secondary lifting arm 106 away from the first mounting plate 101; the upper half of the vertical shaft 109 is provided with threads, and a quick-release nut 111 is threadedly assembled thereon.

[0031] As Figures 1 - 3As shown in the figure, a support frame 112 is installed between the bottom of the main support arm 103 and the first mounting plate 101. On both sides of the top of the main support arm 103, widened wing plates 113 are provided. The two ends of the support frame 112 are respectively fixed to the bottom of the main support arm 103 and the surface of the first mounting plate 101 by screws, and the main support arm 103 and the first mounting plate 101 are combined to form a triangular reinforcement structure. On the one hand, it can improve the load-bearing capacity of the lifting component. On the other hand, it can also position the installation angle of the entire lifting component to prevent the horizontal angle deviation of the lifting component. The design of the widened wing plate 113 can improve the stability of the plate when it is lifted.

[0032] Due to the different actual situations of the material taking positions and raw materials, each piece of plate is not exactly the same. In order to make full use of the plate, when each plate is fed for cutting, the operator needs to adaptively adjust the feeding angle of the plate according to the actual situation of the plate. During the adjustment process, one end of the measuring rule 3 needs to be squeezed to achieve the purpose of adjusting the cutting path of the wood board and the cutting position of the saw blade. The automatic return mechanism 2 includes a second mounting plate 201 installed on the side frame of the belt conveyor of the automatic board reforming equipment. At the top of the second mounting plate 201, an installation cylinder 202 is fixed; at the end of the installation cylinder 202 away from the lifting mechanism 1, a linear bearing 203 is fixed. A capped plug rod 204 is slidably inserted inside the linear bearing 203. A connecting arm 207 is inserted at the front end of the plug rod 204; a pin 209 for installing the measuring rule 3 is vertically fixed at the end of the connecting arm 207; a end cap 206 is sleeved outside the front end of the plug rod 204. The end cap 206 and the connecting arm 207 are both fixedly installed on the plug rod 204 through positioning bolts 208. A spring 205 is also sleeved outside the plug rod 204 between the end cap 206 and the installation cylinder 202. The design of the spring 205 is mainly that when one end of the measuring rule 3 connected to the connecting arm 207 is squeezed, the connecting arm 207 contracts and the spring 205 is compressed. When the plate is completely conveyed into the board reforming equipment, the measuring rule 3 loses the external force extrusion, and the spring 205 resets to drive the front end of the measuring rule 3 to automatically reset, so as to facilitate the operator to adjust the angle of the next piece of wood.

[0033] In order to enable the measuring rule 3 to flexibly adjust adaptively with the length change of the lifting component, the measuring rule 3 is designed with a telescopic structure. Specifically, the measuring rule 3 includes a first ruler 301 and a second ruler 302. The middle part of the first ruler 301 is designed as a hollow slot 102, and a plug-in part 303 is integrally formed at the front end of the second ruler 302. The second ruler 302 is movably inserted and matched with the first ruler 301 through the plug-in part 303. A second fastening bolt 304 is threadedly assembled at one end of the first ruler 301 close to the second ruler 302.

[0034] Among them, further, as Figures 2 - 3As shown, the outer dimensions of the first ruler 301 and the second ruler 302 are the same, so that the surfaces of both ends of the straightedge 3 for abutting against one side of the wooden board are at the same plane height, and the change in the length of the straightedge 3 will not affect the reference accuracy of the cutting angle.

[0035] In order to achieve flexible assembly between the straightedge 3, the automatic return mechanism 2 and the lifting mechanism 1 and avoid problems of movement interference, such as Figures 2 - 3 shown, one end of the first ruler 301 away from the second ruler 302 is rotatably sleeved on the pin pile 209 through a bearing. At the same time, a sleeve 305 is integrally formed at one end of the second ruler 302 away from the first ruler 301, and the sleeve 305 is movably sleeved on the outside of the lower half of the vertical shaft 109.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
