Description

Technical Field

[0001] This utility model belongs to the field of door panel processing equipment, and in particular relates to a soundproof door panel processing device. Background Technology

[0002] The existing wooden door structure includes a door frame fixed in a doorway. The door frame includes a top beam, with side beams at both ends. The lower ends of the side beams touch the ground. A door panel is installed within the door frame. One side of the door panel is hinged to one of the side beams, and the other end of the door panel is locked to the other side beam. To improve the sound insulation of the wooden door, the most common measure is to install sealing strips on the door frame. The sealing strips fill the gaps between the door panel and the door frame, effectively blocking sound transmission and providing good sound insulation while also acting as a buffer.

[0003] However, wooden doors are generally interior doors, and interior floors need to be kept flat. Since sealing strips cannot be installed on the floor, gaps will appear between the door panel and the floor, reducing sound insulation. A solution is to create a groove at the bottom of the door panel, not extending through both sides of the width of the door panel. A lifting mechanism is installed within the groove, with a sealing strip at its bottom. When the door is closed, the lifting mechanism lowers the sealing strip, eliminating the gap between the door panel and the floor and improving sound insulation. When the door is opened, the lifting mechanism raises the sealing strip, preventing the door panel from contacting the floor and allowing for smooth opening.

[0004] The processing device used for grooving door panels, such as the end-face grooving machine in application number 202021558536.2, includes a lifting platform. A feed table is located on one side of the lifting platform, and a grooving motor is mounted on the feed table. The output end of the grooving motor is equipped with a drill bit (actually a milling cutter). The feed table can drive the grooving motor to move along the length and width of the lifting platform. The feed table includes a support frame, with a third platform at the top of the support frame. A second platform is slidably connected above the third platform, and a first platform is slidably connected above the second platform. The movement direction of the first platform is perpendicular to the movement direction of the second platform, and the movement direction of the first platform points towards the lifting platform. The grooving motor is fixed on the first platform. The method of use is as follows: multiple door panels are stacked on the lifting platform, with the height of the bottom door panel corresponding to the height of the milling cutter. The milling cutter moves forward towards the bottom door panel, then along the width of the door panel, and then backward, thus creating a groove at the bottom of the door panel. The lifting platform descends approximately the thickness of one door panel before grooving the next door panel, and this process is repeated until all door panels are grooved.

[0005] The existing processing equipment has the following defects: the door panels are made of wood, which has a certain amount of deformation and tolerance. ISO18769:2017 "Wooden doors and windows - Dimensional tolerances" stipulates that the tolerance range for door panels is ±0.5mm. The height of the lifting platform each time it descends needs to be adjusted according to the thickness of the corresponding door panel in order to ensure that the groove is centered, which greatly reduces production efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a soundproof door panel processing device. This invention has the advantage of high production efficiency.

[0007] The technical solution of this utility model: A soundproof door panel processing device includes a lifting platform, a feeding platform on one side of the lifting platform, a grooving motor on the feeding platform, the feeding platform can move the grooving motor in both the length and width directions of the lifting platform, a milling cutter is provided at the output end of the grooving motor, a positioning roller is provided above the end of the lifting platform near the feeding platform, both ends of the positioning roller are provided with support columns connected to the ground, a first telescopic cylinder connected to the feeding platform is provided on one side of the positioning roller, and a first push block is provided at the telescopic end of the first telescopic cylinder.

[0008] In the aforementioned soundproof door panel processing device, a second telescopic cylinder is provided above the end of the lifting platform away from the feeding platform. The telescopic end of the second telescopic cylinder is provided with a second push block. The height of the second push block is lower than that of the first push block. The second telescopic cylinder is fixed to the lifting platform.

[0009] In the aforementioned soundproof door panel processing device, the top of the support column is provided with a groove, a bearing for connecting the positioning roller is provided in the groove, a support is provided on the outside of the bearing, the support is slidably connected to the support column, a baffle fixed to the support is provided on the top of the groove, and a spring is provided between the baffle and the support.

[0010] In the aforementioned soundproof door panel processing device, both sides of the support are provided with vertical sliding grooves, and the sliding grooves are provided with sliding strips fixed to the side walls of the grooves.

[0011] In the aforementioned soundproof door panel processing device, the feeding table includes a support, a third platform is provided on the top of the support, a second platform is slidably connected above the third platform, a first platform is slidably connected above the second platform, the moving direction of the first platform is perpendicular to the moving direction of the second platform, the moving direction of the first platform points towards the lifting platform, and the grooving motor is fixed on the first platform.

[0012] In the aforementioned soundproof door panel processing device, a transverse screw is provided between the third platform and the second platform, and a transverse nut fixed to the second platform is provided on the transverse screw. A transverse drive motor with its output end connected to the transverse screw is provided on one side of the third platform. A longitudinal screw is provided between the second platform and the first platform. A longitudinal nut fixed to the first platform is provided on the longitudinal screw. A longitudinal drive motor with its output end connected to the longitudinal screw is provided on one side of the second platform.

[0013] In the aforementioned soundproof door panel processing device, the lifting platform is provided with a positioning mechanism for positioning the door panel in the width direction.

[0014] Compared with the prior art, this utility model sets a positioning roller above the existing lifting platform. The positioning roller makes the height of the door panel in the slot correspond to the height of the milling cutter, ensuring that the slot is centered. The lifting platform only needs to rise to the limit height position, without repeated adjustments, thus improving production efficiency.

[0015] By setting a first telescopic cylinder to push the fully slotted door panel away from under the positioning roller, it is easy for the next door panel to contact the positioning roller. The previous door panel is left on the stack so that the next door panel can be slotted. After all the door panels are slotted, the door panels are unloaded from the lifting platform, which improves production efficiency.

[0016] By setting a second telescopic cylinder, which operates before the door panel is slotted, the door panel is positioned accurately on the lifting platform, ensuring that the slotting depth of the door panel is consistent and accurate, resulting in a high slotting qualification rate.

[0017] By setting a spring, the positioning roller applies downward pressure to the door panel in the slot, preventing the door panel from moving under the cutting force of the milling cutter, thus further improving the slotting qualification rate.

[0018] In addition, by improving the structure of the feed table, it is easier to automate the process, enabling the processing device to automatically and completely groove all the door panels on the lifting platform, thereby further improving production efficiency. Attached Figure Description

[0028] A positioning roller 4 is provided above one end of the lifting platform 3 near the feed platform. Both ends of the positioning roller 4 are provided with support columns 5 connected to the ground. The top of the support column 5 is provided with a groove 10. The groove 10 is provided with a bearing 11 that connects to the positioning roller 4. A support 12 is provided on the outside of the bearing 11. The top of the groove 10 is provided with a baffle 13 that is fixed to the support 12. A spring 14 is provided between the baffle 13 and the support 12.

[0030] The lifting platform 3 is equipped with a positioning mechanism for positioning the door panel 28 in the width direction. The width positioning mechanism includes four positioning shafts 27 whose lower ends are rotatably connected to the lifting platform 3. When the door panel 28 is placed on the lifting platform 3, there are two positioning shafts 27 on each side of the door panel 28 in the width direction.

[0031] Both the first telescopic cylinder 6 and the second telescopic cylinder 8 can be either dual-shaft pneumatic cylinders or dual-shaft electric cylinders.

[0032] Instructions for use: Includes the following actions: (1) Adjust the lifting platform 3 to a low position and stack multiple door panels 28 on the lifting platform 3. One end of the door panel 28 is located below the positioning roller 4. At this time, the front and back positions of the top door panel 28 need to be manually adjusted to ensure the groove depth. The positions of the subsequent door panels 28 do not need to be adjusted. They can be adjusted by the second telescopic cylinder 8.

[0033] (2) When the lifting platform 3 is raised to the high position and cannot continue to rise, the top door panel 28 contacts the positioning roller 4, the support 12 contacts the baffle 13, the uppermost door panel 28 is at the same height as the milling cutter 2 and the first push block, and the next uppermost door panel 28 is at the same height as the second push block 9.

[0034] (3) The longitudinal drive motor 26 drives the longitudinal screw 24 to rotate in the forward direction.
