Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, and in particular to a double-overlapping wheel automatic blade adjusting edge banding finishing device. Background Technology

[0002] like Figure 1 and Figure 2 As shown, generally, edge sealing strips 100a are pasted on the side of the board 100. In order to prevent the edge sealing strips 100a from failing to cover the side of the board 100, the width of the edge sealing strips 100a is usually set to be slightly larger than the thickness of the board 100. After the edge sealing is completed, the excess parts at the top and bottom ends of the edge sealing strips 100a are sanded off using edge sealing finishing equipment so that the edge sealing strips 100a are flush with the board 100.

[0003] Existing edge banding finishing equipment includes:

[0004] Clamping mechanism 1;

[0005] The lifting assembly 2 includes a lifting seat body 202 and a lifting spring 203 that drives the lifting seat body 202 to slide upward.

[0006] The clamping wheel 3 is mounted on the lifting seat body 202 and is used to cooperate with the clamping mechanism 1 to clamp the plate 100 to be trimmed.

[0007] The finishing roller 4 is installed on the lifting seat body 202 and is used to trim the edge sealing strip 100a on the side of the plate 100.

[0008] like Figure 3 As shown, initially, the distance between the clamping roller 3 and the clamping mechanism 1 is less than the thickness of the plate 100. Theoretically, when the plate 100 enters the space between the clamping roller 3 and the clamping mechanism 1:

[0009] S101: The plate 100 will press down on the pressure roller 3, which will cause the lifting seat body 202 to press down on the lifting spring 203. The pressure roller 3 will move down a short distance with the lifting seat body 202.

[0010] S102: Subsequently, under the lifting action of the compression spring, the pressing wheel 3 moves upward with the lifting seat body 202 and cooperates with the pressing mechanism 1 to press the plate 100. At the same time, the precision cutting roller 4 trims the edge sealing strip 100a.

[0011] However, in reality, to improve production efficiency, the sheet material 100 generally enters between the pressure roller 3 and the pressure mechanism 1 at a certain speed, that is:

[0012] In step S101 above, the plate 100 does not gently press down on the pressing wheel 3, but rushes towards the pressing wheel 3 with a certain speed. At this time, the pressing wheel 3 is subjected to the impact force and will first descend a longer distance (the maximum distance between the pressing wheel 3 and the pressing mechanism 1 is generally greater than the thickness of the plate 100), and then move upward to press the bottom surface of the plate 100 under the action of the lifting spring 203.

[0013] Because the downward stroke of the clamping roller 3 is relatively large, the time required for the clamping roller 3 to rise again to clamp the plate 100 is relatively long. During this period, the plate 100 is fed forward at the original speed. Therefore, when the clamping roller 3 rises again to clamp the plate 100, the front end of the plate 100 has already passed the position of the finishing cutter 4. Thus, the front end of the plate 100 is not finished during each finishing operation.

[0014] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0015] One objective of this invention is to provide a double-layered wheel automatic blade adjustment edge banding finishing device, which can effectively solve the problem that existing edge banding finishing devices cannot effectively trim the front end of the board.

[0016] To achieve the above objectives, the present invention provides a double-overlapping wheel automatic knife-adjusting edge-sealing finishing device, comprising:

[0017] Clamping mechanism;

[0018] A lifting assembly, located below the pressing mechanism;

[0019] A clamping wheel is mounted on the lifting assembly and is used to cooperate with the clamping mechanism to clamp the plate to be trimmed; wherein, the clamping wheel includes a central wheel and an eccentric wheel that rotates eccentrically relative to the central wheel;

[0020] A finishing roller cutter is installed on the lifting assembly and is used to trim the edge sealing strips on the side of the board.

[0021] Optionally, the lifting assembly includes a base, a lifting seat body slidably connected to the base, and a lifting spring that drives the lifting seat body to slide upward.

[0022] Both the pressure roller and the finishing cutter are rotatably mounted on the lifting seat body.

[0023] Optionally, the clamping wheel further includes a Z-shaped connecting rod, and the center wheel and the eccentric wheel are eccentrically connected through the Z-shaped connecting rod.

[0024] Optionally, the Z-shaped link includes:

[0025] The first rotating shaft has one end mounted on the lifting seat body, and the center wheel is rotatably mounted on the middle of the first rotating shaft;

[0026] A rotating connecting plate, one end of which is hinged to the other end of the first rotating shaft;

[0027] The second rotating shaft has one end rotatably connected to the rotating connecting plate, and the eccentric wheel is rotatably mounted on the other end of the second rotating shaft.

[0028] Optionally, the first rotating shaft and the central wheel, and the second rotating shaft and the eccentric wheel are both connected by rolling bearings.

[0029] Optionally, the diameters of the central wheel and the eccentric wheel are equal.

[0030] Optionally, there are two sets of clamping rollers and two sets of finishing cutters, and one set of finishing cutters is provided on the inner side of each set of clamping rollers.

[0031] Optionally, one set of the pressure rollers and finishing cutters is located below the sheet metal for finishing the lower part of the edge banding strip;

[0032] Another set of pressure rollers and finishing cutters is located above the sheet metal and is used to finish the upper part of the edge sealing strip.

[0033] The beneficial effect of this invention is that it provides a double-overlapping roller automatic blade adjusting edge banding finishing device. When the sheet material enters between the pressing roller and the pressing mechanism, the working process is as follows:

[0034] First, the plate will press down on the eccentric wheel. After being impacted by the plate, the eccentric wheel will rotate on one hand and drive the entire lifting seat body to slide down slightly on the other hand.

[0035] During this process, the eccentric wheel will rotate to a certain extent, thereby offsetting part of the kinetic energy of the plate when it hits the pressing wheel. Although the remaining kinetic energy can also drive the lifting seat body to slide downward, it can no longer make the lifting seat body slide down significantly. That is, the lifting seat body slides down a small distance, which can effectively avoid the problem that "the pressing wheel will fall a long distance first".

[0036] Next, the board continues to move forward, and under the lifting action of the compression spring, the center wheel quickly moves upward with the lifting seat body and works with the pressing mechanism to press the board. At the same time, the finishing cutter rises to trim the edge sealing strip at the end position, thus avoiding the problem of not being able to trim the front end of the board.

[0037] Therefore, the double-layer wheel automatic blade adjustment edge banding finishing equipment provided by the present invention can effectively reduce the downward stroke of the pressing wheel when it is impacted by the board, thereby solving the problem that the existing edge banding finishing equipment cannot effectively trim the front end of the board.

They are used only for the purpose of describing the present invention and are not intended to indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of the present invention.

[0054] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0055] This invention provides a double-layered wheel automatic blade adjustment edge banding finishing device, which is suitable for applications involving the finishing of edge banding strips on the sides of boards. It can effectively solve the problem that existing edge banding finishing devices cannot effectively finish the front end of the board.

[0056] See Figure 4 and Figure 5 The double-layer wheel automatic knife-adjusting edge-sealing finishing equipment includes a pressing mechanism ( Figure 4 and Figure 5 1. Lifting assembly 2. Pressure roller 3. Finishing cutter 4. (not shown)

[0057] The lifting assembly 2 is located below the pressing mechanism and includes a base 201, a lifting seat body 202 that is slidably connected to the base 201, and a lifting spring 203 that drives the lifting seat body 202 to slide upward; the pressing wheel 3 and the finishing cutter 4 are both rotatably mounted on the lifting seat body 202.

[0058] See Figure 6 The pressing wheel 3 is mounted on the lifting assembly 2 and is used to cooperate with the pressing mechanism to press the plate 100 to be trimmed; wherein, the pressing wheel 3 includes a center wheel 301, a Z-shaped connecting rod 302, and an eccentric wheel 303 that is eccentrically connected to the center wheel 301 through the Z-shaped connecting rod 302.

[0059] Furthermore, the diameters of the central wheel 301 and the eccentric wheel 303 are equal.

[0060] In this embodiment, the Z-shaped connecting rod 302 includes a first rotating shaft 3021, a rotating connecting plate 3022, and a second rotating shaft 3023. One end of the first rotating shaft 3021 is mounted on the lifting seat body 202, and the center wheel 301 is rotatably mounted on the middle of the first rotating shaft 3021. One end of the rotating connecting plate 3022 is hinged to the other end of the first rotating shaft 3021. One end of the second rotating shaft 3023 is rotatably connected to the rotating connecting plate 3022, and the eccentric wheel 303 is rotatably mounted on the other end of the second rotating shaft 3023.

[0061] Furthermore, the first rotating shaft 3021 and the center wheel 301, and the second rotating shaft 3023 and the eccentric wheel 303 are both connected by rolling bearings 3024.

[0062] The finishing roller 4 is installed on the lifting assembly 2 and is used to trim the edge sealing strip 100a on the side of the plate 100.

[0063] The double-layer roller automatic blade-adjusting edge-sealing finishing equipment provided in this embodiment operates as follows when the sheet material 100 enters between the pressing roller 3 and the pressing mechanism:

[0064] S201: First, the plate 100 will press down on the eccentric wheel 303. After the eccentric wheel 303 is impacted by the plate 100, it will rotate clockwise on the connection of the Z-shaped connecting rod 302, and on the other hand, it will drive the entire lifting seat body 202 to slide down slightly through the Z-shaped connecting rod 302.

[0065] It should be noted that during this process, the eccentric wheel 303 will rotate to a certain extent, thereby offsetting part of the kinetic energy of the plate 100 when it rushes towards the pressure wheel 3. Although the remaining kinetic energy can still drive the lifting seat body 202 to slide downward, it can no longer make the lifting seat body 202 slide down significantly. That is, the downward stroke of the lifting seat body 202 is small, which can effectively avoid the problem that "the pressure wheel 3 will fall a longer distance first".

[0066] S202: The plate 100 continues to move forward, and under the lifting action of the compression spring, the center wheel 301 quickly moves upward with the lifting seat body 202 and cooperates with the pressing mechanism to press the plate 100. At the same time, the finishing roller 4 just rises to trim the edge sealing strip 100a at the end position, thereby avoiding the problem of not being able to trim the front end of the plate 100.

[0067] Therefore, the double-roller automatic blade-adjusting edge banding finishing equipment provided in this embodiment can effectively reduce the downward stroke of the pressing roller 3 when it is impacted by the board 100, thereby solving the problem that the existing edge banding finishing equipment cannot effectively trim the front end of the board 100.

[0068] Optionally, in this embodiment, there are two sets of pressure rollers 3 and two sets of finishing cutters 4, and one set of finishing cutters 4 is provided on the inner side of each set of pressure rollers 3.

[0069] One set of the pressing rollers 3 and the finishing rollers 4 are located below the plate 100 and are used to finish the lower part of the edge sealing strip 100a; the other set of the pressing rollers 3 and the finishing rollers 4 are located above the plate 100 and are used to finish the upper part of the edge sealing strip 100a.

[0070] The double-layered wheel automatic blade-adjusting edge-sealing finishing equipment provided in this embodiment has the following advantages:

[0071] ①A lifting spring 203 is provided below the lifting seat body 202 so that the pressing wheel 3 can adaptively press the plate 100 of various sizes and thicknesses and facilitate the finishing mechanism to adaptively trim the edges of the plate 100 of various thicknesses and sizes.

[0072] ② The pressure roller 3 with a double-layered structure is set up to effectively reduce the downward stroke of the pressure roller 3 when it is impacted by the board 100, thereby solving the problem that the existing edge banding and finishing equipment cannot effectively trim the front end of the board 100.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole.
