Description

Technical Field

[0001] The invention relates to the technical field of fire door processing equipment, in particular to a dust-proof cutting device for processing wooden fire doors. Background Art

[0002] A wooden fire door is a door used in buildings to isolate fire sources. It has fire-resistant stability, integrity and thermal insulation.

[0003] Cutting of fire doors is an important step in the production process. Cutting allows fire doors to be customized according to the specific size requirements of the construction site, ensuring that the door leaf and door frame can accurately adapt to their installation location and meet the specifications and size requirements of the building design. The dust problem generated during the cutting of wooden fire doors by electric saw blades is an important occupational health and environmental protection issue. This dust not only pollutes the workshop environment, but also may cause serious harm to the health of operators, such as causing respiratory diseases such as allergic pneumonia.

[0004] The prior art provides an air suction device in the cutting area of ​​the fire door, and places the air suction port of the air suction device close to the cutting saw blade and the cutting processing part of the fire door to remove the dust generated during the cutting process and prevent the dust from floating in the air.

[0005] However, according to investigations, in order to effectively remove the dust generated by cutting, the prior art mostly uses a shell cover that wraps the upper half of the electric saw blade. When the saw blade is running to cut the wooden protective door, the shell cover will block the dust generated on the side of the wooden fire door. Since the lower half of the electric saw blade must meet the cutting operation of fire doors of a certain thickness, it must remain extended relative to the shell cover, resulting in the prior art suction device being difficult to achieve all-round coverage of the cutting part of the fire door, resulting in a poor dust prevention effect. In addition, the prior art has the problem of cumbersome and low efficiency in cleaning the dust and debris accumulated in the suction device. If the dust and debris accumulated inside the suction device are not cleaned in time, it is not conducive to effective control of the dust generated during the cutting process of batch wooden fire doors.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 5 The present invention provides a technical solution: a dust-proof cutting device for processing wooden fire doors, comprising a platform 1 and a slide seat 2 slidably mounted on the platform 1 and cooperating with the movement and support of the wooden fire door, support arms 3 are slidably arranged on the front and rear sides of the platform 1, and a regulating component for adjusting the distance between the two support arms 3 relative to the platform 1 is arranged in the platform 1.

[0033] The slide 2 is clamped in the center of the wooden fire door to be processed through the existing clamping mechanism, and the platform 1 drives the slide 2 to move horizontally along the platform 1 through the existing linear motor, so that the wooden fire door laid on the slide 2 passes through the electric saw blade 25 for edge trimming.

[0034] By setting the regulating components, the distances between the two arms 3 and the platform 1 are adjusted synchronously and equidistantly, thereby meeting the fixed-distance cutting and processing of wooden fire doors of different sizes and improving the applicability of the device.

[0035] A material receiving shell 7 is rotatably connected to the support arm 3, an air hood 23 opposite to the material receiving shell 7 is arranged on the outer side of the platform 1, an electric saw blade 25 is installed in the air hood 23, a gap is formed between the material receiving shell 7 and the air hood 23 for the wooden fire door to pass through, a frame plate 15 is fixedly provided on the outer end of the support arm 3 through a tube cover 14, a sliding frame 21 is slidably connected to the inner side of the frame plate 15, a side extension frame 26 is fixedly provided between the sliding frame 21 and the air hood 23, an air pump mechanism 12 is installed at the bottom of the material receiving shell 7, an air transmission component is connected between the air hood 23 and the material receiving shell 7, and a brush 24 that contacts the end face of the wooden fire door is installed at the end of the air hood 23 opposite to the material receiving shell 7.

[0036] The electric saw blade 25 is a prior art, which converts electrical energy into mechanical energy through a motor to drive the saw blade to rotate, thereby achieving cutting of the wooden fire door. When the wooden fire door passes through the gap between the air hood 23 and the material receiving shell 7 with the slide 2, the rotating electric saw blade 25 trims the edge of the wooden fire door.

[0037] By means of the air hood 23 and the material receiving shell 7 distributed on the upper and lower sides of the wooden fire door, the cutting part of the wooden fire door is covered. By means of the setting of the brush 24, when the fire door passes through the gap between the air hood 23 and the material receiving shell 7, the flexible brush 24 contacts the upper and lower end faces of the wooden fire door, thereby preventing wood chips and dust from floating outward through the gap, thereby satisfying the all-round wrapping of the cutting area of ​​the wooden fire door. During the cutting process, the waste dust generated on the lower side of the wooden fire door will directly fall into the material receiving shell 7, and the waste dust generated on the upper side of the wooden fire door will be sucked into the air hood 23 and discharged into the material receiving shell 7 through the air transmission component, thereby achieving all-round and effective dust removal during the cutting process of the wooden fire door, improving the production environment of the processing workshop, and at the same time being beneficial to maintaining the health of the staff.

[0038] The air pump mechanism 12 is a prior art, which accelerates the air flow rate at the bottom of the receiving shell 7 by rotating the impeller, so that the air hood 23, under the action of the air delivery component, absorbs the wood dust generated on the upper side during the cutting process of the wooden fire door through its downward opening. By setting the ventilation component, the downward opening of the air hood 23 and the upward opening of the receiving shell 7 form a negative pressure state for dust absorption under the action of the air pump mechanism 12, which is conducive to reducing the investment, maintenance and use costs of the dust removal equipment.

[0039] A driving component for controlling the turning of the receiving shell 7 is installed on the support arm 3, and a transmission member is arranged on the frame plate 15. When the receiving shell 7 is turned over with the opening facing downward, the sliding frame 21 will drive the air cover 23 to move upward under the action of the transmission member.

[0040] When the wood dust in the receiving shell 7 accumulates a lot, the receiving shell 7 is turned over by the driving component. In this process, in order to avoid the electric saw blade 25 extending downward from the air hood 23 from hindering the turning of the receiving shell 7, the transmission member is set so that the receiving shell 7 is turned over and the air hood 23 moves upward under the action of the transmission member to provide space for the turning of the receiving shell 7. The wood dust accumulated in the receiving shell 7 is dumped by the coordinated setting of the driving member and the transmission member, which is conducive to improving the rapid and efficient cleaning of the dust accumulated in the receiving shell 7 during the dust removal process, and meeting the device's effective control of the generated dust when facing the batch processing of wooden fireproof doors.

[0041] Specifically, Figure 2 and Figure 3 As shown, the regulating component includes a rod 4 fixed at the opposite end of two arms 3, the rod 4 slides through the platform 1, and a bidirectional screw 5 rotatably connected to the platform 1 and screwed with the two rods 4 is installed in the platform 1. A first drive motor 6 for controlling the rotation of the bidirectional screw 5 is installed in the platform 1, and a spline is formed on the side of the rod 4 to limit its rotation relative to the platform 1.

[0042] The first drive motor 6 is started to control the rotation of the bidirectional screw 5, so that the frame rod 4 screwed with the bidirectional screw 5 drives the support arm 3 to move relative to the frame 1, and then the electric saw blade 25 installed in the air hood 23 is synchronously and equidistantly adjusted relative to the frame 1, so as to achieve fixed-distance trimming of wooden fire doors of different sizes. The spline setting limits the rotation of the frame rod 4 relative to the frame 1, which is conducive to the rotation of the bidirectional screw 5 to the frame rod 4.

[0043] Specifically, Figure 1-Figure 4 As shown, the gas transmission component includes a first transverse tube 13 connected and fixed on the material receiving shell 7, a second transverse tube 27 connected and fixed at the outer end of the gas cover 23, and a docking assembly connecting the first transverse tube 13 and the second transverse tube 27. The first transverse tube 13 penetrates the support arm 3 and the frame plate 15 outwardly, and rotates coaxially inside the cylinder cover 14.

[0044] The docking assembly includes two curved pipes 28 corresponding to the first transverse pipe 13 and the second transverse pipe 27 , wherein one curved pipe 28 is rotatably connected to the first transverse pipe 13 , and the other curved pipe 28 is fixed to the second transverse pipe 27 , and a bellows 29 is fixedly connected between the two curved pipes 28 .

[0045] When the air pump mechanism 12 blows air downward, the air hood 23 and the material receiving shell 7 are connected to each other through the arrangement of the second transverse pipe 27, the corrugated pipe 29, the two bent pipes 28 and the first transverse pipe 13, so that the dust floating on the upper side of the wooden fire door is sucked into the material receiving shell 7 through the air transmission component.

[0046] The first transverse tube 13, the second transverse tube 27 and the two curved tubes 28 are hard metal tubes, and the bellows 29 is a cylindrical thin-walled corrugated shell with multiple transverse corrugations, which can produce corresponding displacement under the action of pressure, axial force, transverse force or bending moment to meet the change of the distance between the receiving shell 7 and the gas hood 23.

[0047] Specifically, Figure 2-Figure 4 As shown, the driving component includes a gear ring 8 and a gear 9 rotatably connected to the inner side of the support arm 3, and the gear ring 8 is fixedly connected to the outer side of the first cross tube 13. The outer end of the support arm 3 is installed with a second motor 10 for controlling the rotation of the gear 9.

[0048] The second motor 10 is started to control the gear 9 to rotate, so that the gear ring 8 meshing with the gear 9 drives the first transverse tube 13 coaxially fixed thereto to rotate, thereby causing the receiving shell 7 fixed to the first transverse tube 13 to flip.

[0049] The transmission member includes a pulley 18 and a belt ring 17 rotatably connected to the outside of the frame plate 15. The outside of the pulley 18 and the belt ring 17 is sleeved with a transmission belt 19. The belt ring 17 is fixed to the first transverse tube 13. The pulley 18 is provided with a guide assembly.

[0050] When the first transverse tube 13 rotates, the belt ring 17 fixed on the first transverse tube 13 will drive the pulley 18 to rotate synchronously through the transmission belt 19. At this time, the sliding frame 21 will move upward along the frame plate 15 under the action of the guide assembly.

[0051] The guide assembly includes a guide rod 20 fixed on the pulley 18 through a bracket, an arc groove 16 is formed in the frame plate 15 for the guide rod 20 to slide through, and a strip groove 22 is formed in the sliding frame 21 for the guide rod 20 to slide.

[0052] When the pulley 18 rotates, the guide rod 20 fixed on the pulley 18 will pass through the arc groove 16 and slide along the strip groove 22. In this process, the side wall of the guide rod 20 presses the inner wall of the strip groove 22 to drive the sliding frame 21 to move vertically along the frame plate 15, and then the side extension frame 26 fixed to the sliding frame 21 drives the air hood 23 to move relative to the material receiving shell 7.

[0053] Specifically, Figure 5As shown, the receiving shell 7 is provided with an arc-shaped partition net 11 for limiting the wood dust discharged into the receiving shell 7 from scattering outward through the exhaust port of the air pump mechanism 12. By setting the arc-shaped partition net 11, the space for storing wood dust inside the receiving shell 7 is separated from the air pump mechanism 12 at the bottom of the receiving shell 7. The arc-shaped partition net 11 is arranged in an arc structure, which is conducive to increasing the ventilation area of ​​the arc-shaped partition net 11 in a limited space, and at the same time, it is conducive to the dust sucked into the receiving shell 7 to be dispersed and accumulated on both sides of the arc-shaped partition net 11, so that the receiving shell 7 is conducive to maintaining the dust suction ability for a long period of time.

[0054] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
