Description

Technical Field

[0001] This utility model relates to the field of edge banding machines for sheet metal, and specifically to an edge trimming and positioning structure for an edge banding machine. Background Technology

[0002] Currently, edge banding machines are used for side edge banding, trimming, and sanding of boards. During this process, the boards are conveyed longitudinally via a conveyor chain assembly. To prevent relative movement between the boards and the chain links, pressure rollers are used to press down on the upper side of the boards. After side edge banding, a trimming process is required. In this process, the sides of the boards need to be positioned relative to the chamfering cutter head to prevent excessive cutting depth and the formation of excessively large rounded corners. Currently, a conical turntable is used for lateral positioning of the board sides. For example, see Chinese Utility Model Patent Publication No. CN209999368U, "A Pneumatic Trimming Device for a Woodworking Edge Banding Machine," which includes small guide rollers. Figure 9 As shown, the rotation axis of the conical turntable is inclined. When the plate 99 is tilted, the vertical corner edge 991 of the plate 99 will first touch the conical turntable, causing the conical turntable to rotate. The vertical corner edge 991 of the plate 99 is guided (or pushed) by the conical surface of the conical turntable, so that the side edge 992 of the plate eventually passes along the generatrix 971 at the foremost position of the conical turntable. Since the generatrix 971 at the foremost position of the conical turntable is in the vertical direction, the side edge 992 of the plate can be positioned laterally. However, due to the rotating setting of the conical turntable, there is clearance in the bearing connecting the conical turntable, so the aforementioned generatrix 971 will have movement, resulting in poor positioning effect of the side edge 992 of the plate. Moreover, during the process of the conical turntable guiding the plate 99, the conical turntable will generate a vertical component force on the plate 99, which is not conducive to the stable conveying of the plate 99. Therefore, the existing trimming and positioning structure needs to be improved. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an edge-banding machine trimming and positioning structure that has a better positioning effect on the side of the board.

[0004] The objective of this utility model is achieved through the following technical solution.

[0005] The edge-banding machine trimming positioning structure disclosed in this utility model includes a transverse positioning component. The transverse positioning component includes a positioning backing plate and a cylindrical guide wheel for guiding the vertical corner edge of the board. The rotation axis of the cylindrical guide wheel is set in the vertical direction. The positioning backing plate forms a transverse positioning surface for abutting the longitudinal alignment cutter disc on the side of the board. The transverse positioning surface is located on the right side of the cylindrical guide wheel. The positioning backing plate forms a guiding inclined surface. The guiding inclined surface is located in the left-right direction between the front end of the cylindrical guide wheel and the transverse positioning surface. The right end of the guiding inclined surface is connected to the left end of the transverse positioning surface. The left end of the guiding inclined surface is located on the rear side of the transverse positioning surface. The transverse positioning surface is located on the front side of the cylindrical guide wheel.

[0006] Preferably, the left end of the positioning plate has a guide rounded corner, and the left end of the guide slope is connected to the guide rounded corner.

[0007] Preferably, the lateral positioning assembly includes a slide, the cylindrical guide wheel is rotatably connected to the slide, and the positioning plate is mounted on the slide; it also includes a rotating support and a lateral adjustment screw, the slide is slidably disposed on the rotating support, the lateral adjustment screw is rotatably connected to the rotating support, the lateral adjustment screw is screwed to the rear end of the slide, and the slide and the rotating support are fixedly connected by a locking screw.

[0008] Preferably, air jet holes are formed on the guide slope.

[0009] Preferably, the slide has a connector mounting hole extending in the vertical direction, the air jet extends in the front-back direction, and the rear end of the air jet communicates with the connector mounting hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a transverse positioning component including a positioning plate and a cylindrical guide wheel for guiding the vertical corner edge of the plate, the positioning plate forms a transverse positioning surface for abutting the longitudinally aligned cutter head on the side of the plate, the transverse positioning surface is located on the right side of the cylindrical guide wheel, the positioning plate forms a guiding slope, the guiding slope is located in the left-right direction between the front end of the cylindrical guide wheel and the transverse positioning surface, the right end of the guiding slope is connected to the left end of the transverse positioning surface, the left end of the guiding slope is located on the rear side of the transverse positioning surface, and the transverse positioning surface is located on the front side of the cylindrical guide wheel, so that when the cutter head cuts the edge of the side of the plate, the plate obtains a high-rigidity transverse positioning effect. Therefore, the trimming positioning structure of this utility model has a better positioning effect on the side of the plate. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] The edge-trimming positioning structure of the edge-sealing machine of this utility model, such as Figures 1 to 4 As shown, the device includes a lateral positioning assembly 1, which includes a positioning plate 12 and a cylindrical guide wheel 11 for guiding the vertical corner edge 991 of the plate 99. The rotation axis of the cylindrical guide wheel 11 is arranged in the vertical direction, that is, the cylindrical guide wheel 11 has a cylindrical surface, and the rotation axis of the cylindrical guide wheel 11 coincides with the axis of the cylindrical surface. The positioning plate 12 has a lateral positioning surface 121 for abutting against the longitudinal alignment cutter disc 4 on the side 992 of the plate. Figure 2 As shown, that is, in the longitudinal direction of the transfer of the plate 99, the rotation axis of the cutter head 4 is at the same position as the transverse positioning surface 121, as shown. Figure 3As shown, when the plate 99 moves from left to right, the transverse positioning surface 121 is located on the right side of the cylindrical guide wheel 11. That is, the plate 99 first reaches the corresponding position on the cylindrical guide wheel 11 and then reaches the corresponding position on the transverse positioning surface 121. Figure 8 As shown, the positioning plate 12 has a guide slope 122, which is located at the front end of the cylindrical guide wheel 11 in the left-right direction (that is to say...). Figure 8 Between the front end 111 of the guide wheel and the transverse positioning surface 121, the right end of the guide ramp 122 is connected to the left end of the transverse positioning surface 121. The left end of the guide ramp 122 is located on the rear side of the transverse positioning surface 121, that is, the guide ramp 122 and the transverse positioning surface 121 form an angle greater than 180°. Specifically, the guide ramp 122 and the transverse positioning surface 121 form an angle of about 181° to 182°. The transverse positioning surface 121 is located on the front side of the cylindrical guide wheel 11. In other words, the transverse positioning surface 121 is located on the front side of the front end 111 of the guide wheel to avoid the cylindrical guide wheel 11 from interfering with the transverse positioning surface 121 abutting against the side 992 of the plate.

[0023] The following is a brief explanation of the working principle of the trimming and positioning structure of this utility model: Figure 3 and 4 As shown, the plate 99 is conveyed to the right. When the plate 99 becomes horizontally skewed, the vertical corner edge 991 at the right rear end of the plate 99 may extend beyond the horizontal positioning surface 121, meaning the position of the plate 99 exceeds its normal operating range. Consequently, the vertical corner edge 991 at the right rear end of the plate 99 will touch the outer cylindrical surface of the cylindrical guide wheel 11. As the plate 99 is conveyed to the right, while the vertical corner edge 991 drives the cylindrical guide wheel 11 to rotate, the cylindrical guide wheel 11 also guides the vertical corner edge 991 to move forward. Therefore, the cylindrical guide wheel 11 can provide a significant correction effect on the plate 99. Figure 8 As shown, the vertical corner edge 991 will then pass through the guide slope 122 of the positioning plate 12. Since the positioning plate 12 is fixed (when the edge banding machine is operating normally), the guide slope 122 provides a small correction effect on the board 99. The vertical corner edge 991 slides along the guide slope 122, gradually crawling forward to the front end of the positioning plate 12, that is, the vertical corner edge 991 slides along the transverse positioning surface 121. Since the transverse positioning surface 121 is longitudinally aligned with the cutter head 4, as shown... Figure 2 As shown, the transverse positioning surface 121 is located directly above the rotation axis of the cutter head 4, as... Figure 7 As shown, the cutter head 4 continues to rotate, and the lower edge of the side surface 992 of the plate is rounded by the cutter head 4. That is to say, when the cutter head 4 is cutting the lower edge of the side surface 992 of the plate, the transverse positioning surface 121 just positions the side surface 992 of the plate, which can achieve an effective cutting positioning effect. During this process, such as Figure 2 As shown, the trimming device is equipped with a fixedly installed lower positioning tray 2, such as... Figure 4 and Figure 7 As shown, the bottom surface of plate 99 rests against the upper end of the outer cylindrical surface 201 of the lower positioning tray 2. (As indicated...) Figure 1 and Figure 7 As shown, the trimming device also includes a cutter head 4 for forming a chamfer on the upper edge of the side panel 992 of the board. That is, the trimming device has two cutter heads 4, one above the other, which are staggered left and right. Correspondingly, the trimming device has an upper positioning tray 3 for the board 99 to rest against. The cutter head 4 for forming a chamfer on the upper edge of the side panel 992 also has a corresponding trimming positioning structure. The trimming positioning structure corresponding to the cutter head 4 for forming a chamfer on the lower edge of the side panel 992 is symmetrical to the trimming positioning structure corresponding to the cutter head 4 for forming a chamfer on the upper edge of the side panel 992. Figure 5 As shown, the plate 99 passes through two cutter discs 4, which round the upper and lower edges of the plate side 99. As can be seen from the above, this utility model uses a rotatable cylindrical guide wheel 11 to achieve a large-scale correction of the plate 99, and then uses a fixed guide inclined surface 122 to perform a smaller-scale correction of the plate 99, so that the plate 99 can smoothly transition to abut against the transverse positioning surface 121 (fixed setting). Therefore, when the cutter disc 4 cuts the lower (or upper) edge of the plate side 992, the plate 99 obtains a high-rigidity transverse positioning effect. Therefore, the trimming positioning structure of this utility model has a good positioning effect on the side of the plate. When the cylindrical guide wheel 11 contacts the plate 99, since the surface of the cylindrical guide wheel 11 is a vertical cylindrical surface, the cylindrical guide wheel 11 will not generate a reaction force in the vertical direction on the plate 99, which is conducive to the stable conveying of the plate 99.

[0024] Furthermore, such as Figure 8 As shown, a guide rounded corner 1221 is formed on the left end of the positioning plate 12, and the left end of the guide slope 122 is connected to the guide rounded corner 1221. So when the vertical corner edge 991 of the plate 99 transitions from the cylindrical guide wheel 11 to the guide slope 122, if the vertical corner edge 991 contacts the left end of the guide slope 122, the guide rounded corner 1221 will guide the vertical corner edge 991 onto the guide slope 122.

[0025] Furthermore, such as Figure 5 and Figure 6As shown, the transverse positioning assembly 1 is provided with a slide 13, and the cylindrical guide wheel 11 is rotatably connected to the slide 13 through corresponding bearings. The positioning plate 12 is installed on the slide 13 through corresponding screws. The trimming positioning structure of this utility model also includes a rotating support 6 and a transverse adjustment screw 7. The slide 13 is slidably disposed on the rotating support 6. Specifically, a groove is formed at the bottom of the slide 13, and a convex rail is formed on the rotating support 6. The convex rail is slidably disposed in the groove. The transverse adjustment screw 7 is rotatably connected to the rotating support 6 and screwed to the rear end of the slide 13. The slide 13 and the rotating support 6 are fixedly connected by a locking screw 131. Specifically, the slide 13 has an elongated hole extending in the front-to-back direction. The locking screw 131 passes through the elongated hole and is screwed onto the rotating support 6. When the locking screw 131 is loosened, rotating the lateral adjustment screw 7 will move the cylindrical guide wheel 11 and the positioning plate 12 back and forth for adjustment. During this process, the locking screw 131 slides within the elongated hole, laterally adjusting the positioning plate 12 so that it aligns with the cutting edge of the cutter head 4. This allows for the machining of a suitable rounded corner on the lower (or upper) edge of the side panel 992 of the plate. After adjustment, tightening the locking screw 131 will restore the positioning plate 12 to its fixed state.

[0026] Furthermore, such as Figure 2 As shown, an air jet hole 1222 is formed on the guide slope 122. When the cutter head 4 cuts the lower (or upper) edge of the side 99 of the plate, it will produce debris and filaments. The compressed air ejected from the air jet hole 1222 can blow away the debris and filaments, thus preventing the debris and filaments from being stuck between the side 99 of the plate and the transverse positioning surface 121.

[0027] Furthermore, such as Figure 2 and Figure 8 As shown, the slide 13 has a connector mounting hole 132 extending in the vertical direction, and an air jet hole 1222 extending in the front-back direction. The rear end of the air jet hole 1222 is connected to the connector mounting hole 132. The connector mounting hole 132 can be screwed to install a pneumatic connector (e.g., an external thread straight-through). A flexible air tube is connected to the pneumatic connector. Compressed air is input into the connector mounting hole 132 through the flexible air tube, and then compressed air is ejected from the air jet hole 1222. An air jet hole 1222 can also be formed on the right side of the transverse positioning surface 121.
