Description

Technical Field

[0001] The invention relates to the technical field of fire door production, and in particular to auxiliary assembly equipment for fire doors. Background Art

[0002] Fire doors, as a core component of the building safety system, are designed to resist the spread of fire and ensure a valuable time window for evacuation and fire rescue in an emergency. Such doors are not only required to have high-strength fire resistance, but also to maintain structural integrity in a fire to effectively prevent the penetration of fire and toxic smoke. Fire doors are usually composed of a solid door frame, door leaves that meet the fire rating standards, and special materials filled inside the door leaves (such as fireproof honeycomb cores). These elements work together to form a solid firewall.

[0003] In the production process of fire doors, a crucial link is to accurately assemble the two parts of the door frame (usually the outer frame and the inner frame) with the fireproof honeycomb core. The fireproof honeycomb core has become the preferred material for the internal filling of fire doors due to its unique light weight, high strength, heat insulation and flame retardant properties. However, this assembly process currently mostly relies on manual operation, that is, workers manually align the door frame parts with the fireproof honeycomb core and fix them with specific glue or adhesive.

[0004] Although manual assembly can ensure assembly flexibility and control of details to a certain extent, its inherent limitations are becoming increasingly prominent. First, the efficiency of manual assembly is limited by the workers' technical level, work rhythm and physical condition, making it difficult to achieve efficient and stable production output, especially under large-scale production needs. This bottleneck is particularly obvious. Secondly, manual operation is difficult to ensure the consistency and accuracy of the assembly of each fire door, which increases the volatility of product quality. Furthermore, long-term exposure to glue or adhesives containing harmful chemicals poses a potential threat to workers' health. Occupational health issues such as respiratory irritation and skin allergies cannot be ignored.

The rollers can reduce the friction coefficient between the door frame placement platform 4 and the outer door frame of the fire door, thereby improving the passing rate and moving smoothness of the outer door frame. The door core placement platform 3 is arranged at the rear side of the left end of the conveying platform 2. The conveying platform 2 is equipped with a side plate 201, as shown in FIG. Figure 1-Figure 9As shown, it also includes a gluing mechanism, a cutting mechanism and a material taking mechanism. The gluing mechanism includes a nozzle 5 and a coating roller 6. The nozzle 5 is mounted between the side plates 201. The nozzle of the nozzle 5 adopts a mist nozzle. The coating roller 6 is rotatably connected to the top of the conveying platform 2 through a fixed rod 7. The adhesive is sprayed on the inner frame of the door through the nozzle 5, and then the adhesive is evenly spread by the coating roller 6. The cutting mechanism includes a first driving assembly, a traction rod 14, a driving rod 15, a cross-cutting hot melt knife 16, an L-shaped push rod 18, a longitudinal hot melt knife 20 and a second driving assembly. The door core placement platform 3 and the conveying platform 2 A push table 17 is connected between them, and a cross-cutting hot melt tool 16 is arranged in the push table 17. The first driving assembly is connected to one side of the T-shaped support table 1. The first driving assembly includes a first motor 11, a first screw rod 12 and a guide rod 13. The first motor 11 is fixed to the T-shaped support table 1 through a bracket. The output shaft of the first motor 11 is connected to the first screw rod 12. The guide rod 13 is parallel to the first screw rod 12. The traction rod 14 is sleeved on the outside of the first screw rod 12 and the two are connected by threads. One end of the drive rod 15 is slidably connected to the traction rod 14 and the first screw rod 12 is connected between the two. The other end of the return spring 1501 is slidably connected to the guide rod 13, and the first driving assembly drives the traction rod 14 to move horizontally. The driving rod 15 is equidistantly provided with push rods 1502, and the push rod 1502 pushes the door core, and the cross-cutting hot melt tool 16 cuts the door core horizontally. The L-shaped push rod 18 is slidably connected in the T-shaped support platform 1 and a second return spring 1801 is connected between the two. The driving rod 15 can push the L-shaped push rod 18, and the L-shaped push rod 18 pushes the longitudinal hot melt tool 20 to lift upward, and then the second driving assembly drives the longitudinal hot melt tool 2 0 is moved horizontally, the second driving assembly is composed of a second motor 23 and a second screw 24, the second motor 23 is fixed in the T-shaped support platform 1, the output shaft of the second motor 23 is connected with the second screw 24, the longitudinal hot-melt cutter 20 performs longitudinal cutting on the door core, the picking mechanism includes a picking rod 25, the picking rod 25 is fixed to the traction rod 14, a bending plate 2501 is arranged at the end of the picking rod 25, the bending plate 2501 is rotatably connected to the picking rod 25 through a hinge, and the picking rod 25 can push the outer door frame so that the outer door frame is translated to the inner door frame for assembly.

[0034] like Figure 2 and Figure 3 As shown, the gluing mechanism also includes a fixed rod 7, a V-shaped control rod 8 and a movable block 9. The fixed rod 7 is symmetrically fixed to the side plate 201, and the V-shaped control rod 8 is rotatably connected to the end of the fixed rod 7. One end of the V-shaped control rod 8 is rotatably connected to the coating roller 6, and the other end is provided with a straight groove and the movable block 9 is connected to the groove. A limiting groove 10 is provided at the corresponding position of the side plate 201, and the movable block 9 is slidably connected in the limiting groove 10, and the groove portion of the limiting groove 10 is embedded in the movable block 9.

[0035] like Figure 6 , Figure 7and Figure 8 As shown, the cutting mechanism also includes a moving block 19, a semi-embedded ring 21, a convex shaft 2101 and a lifting bracket 22. The moving block 19 is arranged in the T-shaped support platform 1, and the longitudinal cutting hot melt tool 20 is slidably connected in the moving block 19. The back side of the bottom of the longitudinal cutting hot melt tool 20 is respectively provided with a semi-embedded ring 21 and a convex shaft 2101. The longitudinal cutting hot melt tool 20 is slidably connected to the moving block 19 and a spring is arranged at the connection. The inner ring of the semi-embedded ring 21 is provided with a ball shaft, and the ball shaft can be embedded in the thread of the second screw rod 24, so as to connect the semi-embedded ring 21 with the second screw rod 24. Therefore, when the semi-embedded ring 21 is embedded in the second screw rod 24, the second motor 23 is turned on to drive the second screw rod 24 to rotate, and the second screw rod 24 can drive the semi-embedded ring 21 to move horizontally, thereby driving the moving block 19 and the longitudinal cutting hot melt tool 20. The melting tool 20 moves horizontally, the lifting bracket 22 is fixed in the T-shaped support platform 1 and the middle part is lifted, the L-shaped push rod 18 is provided with an inclined portion 1802 which can push the semi-embedded ring 21 upward, so that the semi-embedded ring 21 is embedded in the second screw rod 24, and the lifting bracket 22 contacts and limits the convex shaft 2101, that is, when the moving block 19 moves horizontally to the middle part of the lifting bracket 22, the lifting bracket 22 can drive the longitudinal cutting hot melt tool 20 to move upward by limiting the convex shaft 2101. The specific height of the longitudinal cutting hot melt tool 20 should be higher than the height of the door core on the conveying platform 2. Therefore, after the transverse cutting hot melt tool 16 cuts the door core into sections horizontally to embed it into the outer door frame, the longitudinal cutting hot melt tool 20 will separate the longitudinal cutting of the door core, so as to achieve the effect of automatically placing the standard specification door core accurately into the outer door frame.

[0036] like Fig. 9 As shown, a check plate 26 is also included, and the check plate 26 is slidably connected to the door frame placement platform 4 through a spring. A wedge block is arranged on the upper end of the check plate 26, and the inclined surface of the wedge block faces the feeding direction of the outer door frame, that is, after the outer door frame enters the door frame placement platform 4 from the external conveyor belt, the inclined surface part of the wedge block on the upper end of the check plate 26 preferentially contacts the outer door frame. At this time, the check plate 26 does not block the outer door frame, and when the outer door frame box conveying platform 2 moves to pass over the check plate 26, the check plate 26 will limit the outer door frame. It has two functions. The first is to limit the position of the outer door frame so that the bent plate 2501 at the end of the material picking rod 25 can accurately push the side of the outer door frame. The second is to prevent the outer door frame from sliding out in the opposite direction, causing the subsequent continuous processing actions to stagnate.

[0037] like Fig.10 As shown, a glue coating roller 27 is also included. The glue coating roller 27 is arranged in the door frame placement platform 4. Unlike the nozzle 5, the glue coating roller 27 applies glue to the outer door frame to further improve the degree of gluing between the outer door frame and the inner door frame. Therefore, a rolling glue coating roller 27 is provided so that the inner surface of the outer door frame can be adhered to the adhesive, thereby improving the stability of subsequent fire door assembly.

[0038] like Fig.11 , Fig.12 and Fig.13 As shown, it also includes a positioning component, which includes a baffle plate 28, a wedge head top block 29 and a latch 30. The baffle plate 28 is rotatably connected to the side plate 201 and a second torsion spring 2801 is provided at the connection. The wedge head top block 29 is slidably connected to the upper part of the baffle plate 28. The latch 30 is slidably connected in the baffle plate 28 and passes through the side plate 201. The wedge head top block 29 can push the latch 30 to move upward and disengage from the side plate 201. That is, when the latch 30 is inserted into the side plate 201, the baffle plate 28 is perpendicular to the conveying direction of the conveying platform 2. At this time, the baffle plate 28 can block the inner door frame so that the inner door frame is located at a specified assembly position (parallel to The door core placement platform 3 and the door frame placement platform 4, at this time the inner door frame can accurately connect the door core and the outer door frame), when the bent plate 2501 at the end of the material picking rod 25 pulls the outer door frame, the outer door frame will contact and push the wedge head top block 29, and the horizontally moving wedge head top block 29 pushes the latch 30 to move upward. After the latch 30 disengages from the side plate 201, the material blocking plate 28 will be able to rotate freely, thereby removing the obstruction to the inner door frame. After the outer door frame and the inner door frame are connected, the conveying platform 2 is started to convey the fire door as a whole. The material blocking plate 28 can be rotated and reset under the action of the second torsion spring 2801 to block and limit the next inner door frame.

[0039] like Figure 5 As shown, a reset push rod 31 is also included. The reset push rod 31 is fixed on the T-shaped support platform 1. The reset push rod 31 can guide the driving rod 15. Because the pushing platform 17 is lifted on one side close to the conveying platform 2, and the first driving component needs to drive the driving rod 15 to reciprocate, a reset push rod 31 with an inclined end is provided. The front end of the reset push rod 31 is inclined. When the driving rod 15 is reset backward, the reset push rod 31 passes through the inclined portion and pushes the driving rod 15 to move upward to pass over the pushing platform 17, thereby ensuring the smooth pulling of the material picking rod 25 to the outer door frame.

[0040] The working principle of the embodiment of the present invention is as follows: the conveying platform 2 is conveyed from right to left, a door frame placement platform 4 is arranged on the front side of the left end of the conveying platform 2, a door core placement platform 3 is arranged on the rear side of the left end of the conveying platform 2, and the gluing mechanism is arranged in the middle of the conveying platform 2, and the inner door frame is placed on the right end of the conveying platform 2 and conveyed to the left. During this period, the nozzle 5 sprays adhesive evenly on the inner side of the inner door frame, and then the inner door frame contacts the movable block 9, and the inner door frame pushes the movable block 9 into the limiting groove 10 for temporary fixation. At this time, the movable block 9 has driven the coating roller 6 to rotate downward through the V-shaped control rod 8, and the coating roller 6 contacts the inner surface of the inner door frame to spread the adhesive evenly. After the inner door frame is separated from the movable block 9, the V-shaped control rod 8 rotates and resets under the action of the first torsion spring 801, and the coating roller 6 will move upward, and the inner door frame moves with the conveying The platform 2 moves to the material blocking plate 28 and stops moving. The first motor 11 is turned on to drive the first screw rod 12 to rotate. The first screw rod 12 drives the traction rod 14 to move forward, and the driving rod 15 moves synchronously. The pushing rod 1502 at the lower end of the driving rod 15 carries the door core forward. During this period, the cross-cutting hot-melt tool 16 segments the middle part of the door core, so that the door core material can be accurately placed in the inner door frame after segmentation. After the pushing rod 1502 completely places the door core material into the inner door frame, it will be located at the front side of the inner door frame. As the first screw rod 12 continues to rotate, the pushing rod 1502 pushes the inner door frame forward a certain distance, that is, the inner door frame pushes the L-shaped push rod 18. The rear end of the L-shaped push rod 18 is provided with an inclined portion 1802, and the L-shaped push rod 18 moves forward through the inclined portion 1802 pushes the semi-embedded ring 21 to move upward, and the semi-embedded ring 21 will be embedded in the second screw rod 24. The second motor 23 is turned on to drive the second screw rod 24 to rotate, and the lifting bracket 22 can drive the longitudinal cutting hot melt tool 20 to move upward by limiting the convex shaft 2101. The specific height to which the longitudinal cutting hot melt tool 20 rises should be higher than the height of the door core on the conveying platform 2. Therefore, after the transverse cutting hot melt tool 16 cuts the door core into sections horizontally to embed it into the outer door frame, the longitudinal cutting hot melt tool 20 will separate the longitudinal cutting of the door core, so as to automatically and accurately place the standard specification door core into the outer door frame. At the same time, the material picking rod 25 moves to the front end of the first screw rod 12 with the traction rod 14, and the bending plate 2501 at the end of the material picking rod 25 rotates again to reset after leaving the outer door frame. To a vertical state, the first motor 11 is controlled to operate in reverse, and the material picking rod 25 moves the outer door frame backward through the bending plate 2501. During this period, the glue roller 27 sprays adhesive to the inner surface of the outer door frame to improve the bonding effect. The outer door frame moving backward will contact and push the wedge head top block 29. The horizontally moving wedge head top block 29 pushes the latch 30 to move upward. After the latch 30 is separated from the side plate 201, the material blocking plate 28 will be able to rotate freely, thereby removing the obstruction to the inner door frame. After the outer door frame and the inner door frame are connected, the conveying platform 2 is started to convey the fire door as a whole. The material blocking plate 28 can be rotated and reset under the action of the second torsion spring 2801 to block and limit the next inner door frame, thereby completing the automatic assembly of the inner door frame, door core and outer door frame.
