Description

Technical Field

[0001] This utility model belongs to the technical field of fire door production equipment, specifically relating to a positioning and pressing device for fire door panels. Background Technology

[0002] In the field of building safety, fire doors are important fire protection facilities. Their quality and performance are directly related to the safety of people's lives and property in the event of a fire. Fire doors are usually composed of a combination of various panels. Among them, the positioning and pressing process of fire door panels is a key link in the manufacturing process of fire doors. The quality and efficiency of this process have a decisive impact on the overall quality and production efficiency of fire doors.

[0003] In the existing fire door manufacturing process, workers undertake heavy and inefficient tasks. On the one hand, in the board loading stage, workers have to manually move the large and heavy magnesium oxide boards. Due to the large size and heavy texture of the magnesium oxide boards, workers need to expend a lot of physical strength during the handling process. Long-term work can easily lead to physical fatigue. Moreover, the speed of manual handling is limited, which makes it difficult to meet the efficiency requirements of large-scale production and greatly restricts the overall production progress. On the other hand, in the glue spraying stage of the fire door frame, workers also need to operate manually.

[0004] Therefore, the existing fire doors have the problem of low production efficiency due to the need to manually spray glue and move magnesium oxide boards during the manufacturing process. Summary of the Invention

[0005] To overcome the problem of low production efficiency in existing fire door manufacturing processes, which require manual application of adhesive and handling of magnesium oxide boards, a positioning and pressing device for fire door panels is proposed.

[0006] The technical solution of this utility model is as follows: a positioning and pressing device for fireproof door panels, including a fixed platform; it also includes an extrusion box and a support plate.

[0013] The beneficial effects of this utility model are as follows: The support plate adsorbs the magnesium oxide fiber board placed below the device, while the extrusion box sprays glue into the door panel to be filled.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-6This utility model provides an embodiment of a positioning and pressing device for fire door panels, including a fixed platform 1; it also includes an extrusion box 2 and a support plate 5. Two fixed platforms 1 are provided, and a bracket 101 is fixedly connected to the upper end of each fixed platform 1. A first bearing 103 is provided on the bracket 101, and a shaft 3 is rotatably mounted on both first bearings 103. A reciprocating transmission assembly is provided on the shaft 3, and two limiting moving platforms 4 are threadedly fixed to the shaft 3. A friction assembly for deceleration adjustment is provided on the limiting moving platforms 4. An extrusion box 2 for spraying adhesive is connected to one end of the two brackets 101 that is close to each other. A sliding assembly is provided on the limiting moving platforms 4, and the sliding assembly includes a first connecting block 4. 05. At the ends of the two first connecting blocks 405 that are close to each other, there is an adsorption component for conveying and feeding materials. The adsorption component includes a support plate 5. The support plate 5 adsorbs the magnesium oxide fiber board placed below the device. At the same time, the extrusion box 2 sprays glue into the door panel to be filled. Then, the reciprocating component drives the support plate 5 to slide and move. During the sliding displacement, the friction component reduces the sliding speed of the support plate 5. The support plate 5 carries the magnesium oxide fiber board to the top of the door panel to be filled and places it. This solves the problem of low work efficiency caused by workers having to manually spray glue and manually carry large magnesium oxide boards during the fire door manufacturing process.

[0023] Please see Figures 2-4 In this embodiment, multiple glue nozzles 203 are provided through the right end of the extrusion box 2. A glue retention chamber 204 is provided inside the extrusion box 2. An injection pipe 201 and an air injection pipe 202 are provided through the upper end of the extrusion box 2. The injection pipe 201 is connected to a glue delivery device, and the air injection pipe 202 is connected to an air pump. By turning on the air pump, the glue nozzles 203 on the extrusion box 2 inject glue into the interior of the fire door frame to be assembled. Motor mounting slots 102 are provided through the front and rear ends of the bracket 101, and the reciprocating rotating assembly package... The device includes a first motor 302, which is placed in a motor mounting slot 102 on a bracket 101 at the front end. A second gear 303 is fixedly connected to the outer wall of the output shaft at the front end of the first motor 302, and a first gear 301 is fixedly connected to the outer wall of the shaft 3. A chain 304 is sleeved between the first gear 301 and the second gear 303. The rotation angle of the limiting moving table 4 can be indirectly controlled by the first motor 302 installed on the motor mounting slot 102, thereby realizing the feeding, positioning and installation of magnesium oxide fiberboard.

[0024] Please see Figures 4-6In this embodiment, a limiting groove 401 is provided at the lower end of the limiting moving stage 4. The sliding assembly includes a T-shaped limiting block 402, which is slidably disposed on the limiting groove 401. Two rotating wheels 403 are rotatably disposed at the front and rear ends of the T-shaped limiting block 402. The arc-shaped outer wall of the rotating wheel 403 is in contact with the lower end of the inner wall of the limiting groove 401. A clamping seat 404 is fixedly connected to the lower end of the T-shaped limiting block 402. The upper end of the first connecting block 405 is rotatably disposed on the clamping seat 404. A support plate 5 is fixedly connected to one end of the two first connecting blocks 405 that are close to each other. Two vacuum adsorption disks 501 are disposed on the support plate 5. The upper end of the vacuum adsorption disks 501 is connected to the negative pressure connecting pipe 502 in a through manner. The friction assembly includes a second connecting block 6. The two limiting moving stages 4 are fixedly connected to one end of the two limiting moving stages 4 that are close to each other. A second connecting block 6 is provided, with a first groove 603 at its upper end and a bearing seat 601 fixedly connected to its lower end. A friction wheel 602 is rotatably mounted on the bearing seat 601. An electric cylinder 604 is placed inside the first groove 603. An L-shaped connecting plate 605 is fixedly connected to the upper end of the telescopic rod of the electric cylinder 604. A friction resistance arc plate 606 is fixedly connected to the lower end of the L-shaped connecting plate 605. The arc-shaped lower end of the friction resistance arc plate 606 matches the arc surface of the friction wheel 602. The lower end of the friction wheel 602 is flush with the upper end of the support plate 5. By activating the electric cylinder 604, its telescopic rod drives the friction resistance arc plate 606 on the L-shaped connecting plate 605 to move downward, causing the friction resistance arc plate 606 to contact the friction wheel 602 and generate resistance, which is used to decelerate the support plate 5 during its sliding process.

[0025] By placing the magnesium oxide fiberboard to be installed below the device, at the circular trajectory position of the support plate 5 on the device, and then placing the fire door frame to be assembled near the extrusion box 2, also at the circular trajectory position of the support plate 5, both positions can be equipped with fixed or transmission-type workbenches. The magnesium oxide fiberboards can be stacked. After placement, connect the injection pipe 201 to the glue delivery device and the air injection pipe 202 to the air pump. By turning on the air pump, the glue nozzle 203 on the extrusion box 2 injects glue into the interior of the fire door frame to be assembled. At the same time, connect the negative pressure connection pipe 502 on the vacuum adsorption plate 501 to the negative pressure device. Then, the output shaft of the first motor 302 drives the first gear 301 on the second gear 303 to rotate, thereby changing the limit position. The rotation angle of the moving table 4 causes the two vacuum adsorption plates 501 on the support plate 5 to adsorb and clamp the magnesium oxide plate below. Then, the first motor 302 changes the tilt angle of the limiting moving table 4, causing the rotating wheel 403 on the sliding component T-shaped limiting block 402 to slide in the limiting groove 401, thereby carrying the support plate 5 to slide towards the extrusion box 2. At the same time, the electric cylinder 604 is activated, causing its telescopic rod to drive the friction resistance arc plate 606 on the L-shaped connecting plate 605 to move downward, so that the friction resistance arc plate 606 and the friction wheel 602 come into contact to generate resistance, which is used to decelerate the support plate 5 during its sliding process. When the support plate 5 is located at the fire door frame, the suction force of the vacuum adsorption plates 501 is released to place the magnesium oxide plate below it under the fire door frame, and then the subsequent positioning and pressing work is carried out.
