Description

Technical Field

[0001] This utility model relates to the technical field of woodworking machinery edge banding equipment, specifically a servo-driven upper and lower edge trimming device. Background Technology

[0002] An edge banding machine is a type of woodworking machinery. As the name suggests, it is used to band the sides of boards. The finishing mechanism is used to remove excess edge banding material from the board after banding, ensuring that the edge banding surface remains flat.

[0003] The edge banding machines currently used in the market adjust the cutting edge and the infeed of the inclined die plate by rotating the lead screw and nut. After adjustment, the lead screw and nut are tightened for self-locking. Therefore, the thickness of the edge strip used is basically fixed, the cutting edge plate R is also fixed, and the distance between the cutting edge and the inclined die plate is also fixed. If two different thicknesses of edge strip need to be edge banded, an extra set is required (one set of upper and lower edge banding devices for edge strips of one thickness). This structure is obviously not suitable for customers with diverse products. Therefore, we propose a servo upper and lower edge banding device. Utility Model Content

[0004] The purpose of this invention is to provide a servo-driven upper and lower trimming device to solve the problem mentioned in the background art. In existing edge banding machines, the adjustment of the cutting edge disc and the inclined die disc's infeed is achieved by rotating a lead screw and nut. After adjustment, the lead screw and nut are tightened for self-locking. Therefore, the thickness of the edge band used is basically fixed, the cutting edge disc R is also fixed, and the distance between the cutting edge disc and the inclined die disc is also fixed. If two different thicknesses of edge band need to be edge banded, an extra set is required (one upper and lower trimming device for edge band of one thickness). This structure is clearly unsuitable for the diverse needs of customers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a servo upper and lower trimming device, comprising a main body assembly, a lower rolling template assembly, a lower slider assembly, an upper slider assembly, a front angle adjustment assembly, a shock absorption and buffer assembly, a lower trimming assembly, an inclined template assembly, a positioning block, a suspension device, and an automatic thickness switching assembly, characterized in that: the top of the main body assembly is respectively provided with an upper rolling template assembly, a rear angle adjustment assembly, an upper trimming assembly, and an adjustment rod assembly;

[0006] The inclined template assembly includes a connecting seat, a bearing seat on one side of the connecting seat, a servo motor mounted on one side of the connecting seat, and a slider short screw on the other side of the connecting seat. The power drive end of the servo motor is connected to a ball screw, and a bearing seat is connected to the outside of the ball screw. The slider short screw is mounted on one side of the connecting seat, and a guide rail slider assembly is mounted on the top of the slider short screw. A side wheel fixing block is mounted on one side of the guide rail slider assembly. A first copper scraper and a template mounting block are mounted on one end of the side wheel fixing block, and an inclined template plate is mounted on one end of the template mounting block. A nut mounting plate is mounted on the top of the guide rail slider assembly.

[0007] The automatic thickness switching component includes a limit rod mounting plate and a cylinder mounting plate. A cylindrical pin is provided on one side of the limit rod mounting plate, an adjusting retaining ring is provided on one side of the cylindrical pin, and an adjusting sleeve is provided at one end of the cylindrical pin.

[0008] The adjusting sleeve is provided with a spring on its outside, the cylinder mounting plate is provided with a lead screw inside, the limiting rod mounting plate is provided with a lead screw on one side, and the cylinder mounting plate is provided with a cylinder inside.

[0009] The upper trimming assembly includes a first motor fixing plate, a first corner motor seat B is provided at the bottom of the first motor fixing plate, a high-configuration corner precision trimming motor L is provided at the bottom of the first corner motor seat B, and the power drive end of the high-configuration corner precision trimming motor L is connected to the left corner precision trimming tool.

A lower dust suction cover is provided on one side of the lower adjusting plate, a second brush is provided at one end of the lower adjusting plate, and a second handle is provided at the top of the lower adjusting plate.

[0013] This utility model has at least the following beneficial effects:

[0014] In use, this device addresses the customer's need to seal both thick and thin edge strips simultaneously. This trimming device uses a servo motor-driven ball screw to adjust the advance and retreat of the inclined die, achieving precise adjustment. Simultaneously, it employs an automatic thickness switching assembly. A cylinder pushes the entire trimming device (including the precision trimming blade and the inclined die plate) out, and the servo motor drives the inclined die plate backward to adjust for thick edge strip scraping. Similarly, the cylinder retracts the entire scraping device (including the precision trimming blade and the inclined die plate), and the servo motor drives the inclined die plate out to adjust for thin edge strip scraping. This operation allows for flexible switching between thick and thin edge strips using a single upper and lower trimming device, meeting the diverse needs of customer products.

The servo motor 1219 drives the inclined die plate 121 to retract, adjusting to a thick edge with scraping. Similarly, the cylinder 1520 retracts the entire scraping device, including the trimming blade and the inclined die plate 121, and the servo motor 1219 drives the inclined die plate 121 to push out, adjusting to a thin edge with scraping. This operation allows a set of upper and lower trimming devices to flexibly switch and adjust between thick and thin edge strips, meeting the diverse needs of customers' products. A servo motor 1219 drives a ball screw 1226 instead of manually rotating a regular screw nut to adjust the in-and-out distance of the inclined mold plate 121, ultimately achieving precise adjustment of the distance between the inclined mold plate 121 and the trimming and finishing blade. The automatic thickness switching component 15 replaces the manual rotation of a regular screw nut for positioning the edge scraping mechanism, and achieves the switching needs of thick and thin edge strip scraping by controlling the extension and retraction of the cylinder 1520.

[0029] Example 2

The difference from the first embodiment is that the high-end corner trimming motor L713 drives the left corner trimming blade 715 to rotate, and the high-end corner trimming motor R1113 drives the right corner trimming blade 1115 to rotate to perform trimming work. The dust generated during trimming is collected by the upper dust hood 28 and the lower dust hood 36. The first brush 210 and the second brush 37 can perform cleaning work.
