Description

Technical Field

[0002] Density board, whose full name is density fiberboard, is also known as fiberboard, medium-density fiberboard, medium-density fiberboard, etc. It is a board made of wood fiber or other plant fiber as raw materials, prepared by fiber, applied with synthetic resin, and pressed under heating and pressurization conditions. It can be divided into high-density fiberboard, medium-density fiberboard and low-density fiberboard according to its density. Among them, medium-density fiberboard is most widely used in furniture and decoration. In the production process of density board, aluminum foil will be pasted on one side of the density board to improve the fire resistance and wear resistance of the density board.

[0003] When the existing pressing equipment is pasting aluminum skin, the corners of the density board cannot be wrapped by the aluminum skin, especially at the front end of the conveying direction during the production of the density board. This will cause the edge of the density board to leak out, reducing the fire and wear resistance of the density board. In addition, the corners of the density board are easily separated from the aluminum skin during later use, reducing the service life of the product. Summary of the invention

[0045] Example 1, reference Figure 1 to Figure 14 , which is the first embodiment of the present invention, and this embodiment provides a density board pressing device and a preparation method. The density board pressing device and the preparation method include a main component 100, including a conveying platform 101, a density board 102, a placement rack 103, an aluminum sheet 104 and an extrusion roller 105. The density board 102 is located on the top of the conveying platform 101, the placement rack 103 is arranged above the conveying platform 101, and the aluminum sheet 104 is placed on the top of the placement rack 103.

[0046] The main component 100 is the existing technology, wherein the conveying platform 101 is used to convey the density board 102, and can stop the density board 102 at an appropriate position so that the aluminum skin 104 can be attached to the top of the density board 102, the placement rack 103 is used to place the aluminum skin 104, and the squeezing roller 105 is used to extrude the density board 102 and the aluminum skin 104 after bonding, so that the density board 102 and the aluminum skin 104 are tightly combined.

[0047] The density board 102 is a board made of wood fiber or other plant fiber as raw materials, which is prepared by fiber preparation, applied with synthetic resin, and pressed under heating and pressure conditions.

[0048] The pressing assembly 200 is arranged on the conveying platform 101, and includes a laminating part 201, a positioning part 202, a bending part 203 and a resetting part 204.

[0050] The fitting 201 includes a suction plate 201a, a pressing column 201b, a first spring 201c, a driving column 201d, a connecting sleeve 201e, a first bending plate 201f and an extrusion column 201g. The suction plate 201a is located at the top of the aluminum sheet 104, the pressing column 201b is fixed to the top of the suction plate 201a, the two ends of the first spring 201c are respectively fixed to the inner wall of the pressing column 201b and the inner wall of the driving column 201d, the driving column 201d slides on the surface of the pressing column 201b, the connecting sleeve 201e is fixed to the bottom of the driving column 201d, the first bending plate 201f is fixed to one side of the connecting sleeve 201e, and the extrusion column 201g is fixed to the two ends of the first bending plate 201f.

[0051] The suction plate 201a is a prior art, and the aluminum skin 104 can be adsorbed by the suction plate 201a, thereby facilitating the transportation of the aluminum skin 104. The pressing column 201b is used to press the suction plate 201a to the top of the density board 102. The first spring 201c is in an extrusion state, providing thrust for the pressing column 201b. A rack is connected above the driving column 201d, so that the driving column 201d can be lifted, moved and translated. The connecting sleeve 201e is used to drive the first bending plate 201f to move, and the first bending plate 201f is used to bend the aluminum skin 104. The extrusion column 201g is used to extrude the positioning piece 202, so that the positioning piece 202 will not affect the bending of the aluminum skin 104.

[0052] Specifically, the positioning member 202 includes a first supporting seat 202a and a supporting platform 202b. The first supporting seat 202a is fixed in the conveying platform 101, and the supporting platform 202b slides in the first supporting seat 202a.

[0053] The first support seat 202a is used to support the support platform 202b, and the support platform 202b is used to support the density board 102, so that when the first bending plate 201f bends the aluminum skin 104, the density board 102 will not bend. A limit strip is fixed on one side of the support platform 202b, and the limit strip slides in the first support seat 202a, and is used to limit the support platform 202b, so that the support platform 202b can move stably.

[0054] Specifically, the positioning member 202 also includes a positioning plate 202d, a stabilizing column 202e and a second spring 202f. The positioning plate 202d is fixed to one side of the first support seat 202a, the stabilizing column 202e is fixed in the support platform 202b, and the two ends of the second spring 202f are respectively fixed to the inner wall of the support platform 202b and one side of the positioning plate 202d, and the stabilizing column 202e slides in the positioning plate 202d.

[0055] The positioning plate 202d is used to support the stabilizing column 202e. The second spring 202f is in a compressed state. Through the restoring elastic force of the second spring 202f, the supporting platform 202b can automatically reset after moving.

[0056] Specifically, the positioning member 202 also includes a baffle 202g, a limiting slider 202h, a positioning column 202i, a third spring 202j and a support plate 202k. The baffle 202g slides on one side of the first support seat 202a, the limiting slider 202h is fixed on both sides of the baffle 202g, the end of the positioning column 202i is fixed to the bottom of the baffle 202g, the third spring 202j is sleeved on the surface of the positioning column 202i, and the support plate 202k is fixed to the bottom of the first support seat 202a.

[0057] The baffle 202g is used to block the density board 102 so that the density board 102 is located in a suitable position to facilitate the posting of the aluminum sheet 104. The limiting slider 202h can make the baffle 202g stably move up and down on one side of the first support seat 202a. The third spring 202j is in a compressed state and is used to support the baffle 202g. When the extrusion column 201g descends, it can squeeze the baffle 202g to move downward.

[0058] Specifically, the bending member 203 includes a second support seat 203f, a tooth plate 203a, a pressure block 203b, a rotating shaft 203c, a connecting gear 203d and a driving gear 203e. The second support seat 203f is fixed in the conveying platform 101, the tooth plate 203a slides in the second support seat 203f, the pressure block 203b is fixed to one side of the tooth plate 203a, the rotating shaft 203c is rotatably connected to the second support seat 203f, and the connecting gear 203d and the driving gear 203e are both fixed on the surface of the rotating shaft 203c.

[0059] The second support seat 203f is used to limit the tooth plate 203a so that the tooth plate 203a can move up and down stably. The tooth plate 203a is meshed with the connecting gear 203d. When the extrusion column 201g descends, the pressure block 203b can be squeezed downward to move the pressure block 203b downward. At this time, the pressure block 203b can drive the tooth plate 203a to move downward, so that the connecting gear 203d drives the driving gear 203e to rotate through the rotating shaft 203c.

[0060] Specifically, the bending part 203 also includes a second bending plate 203g, a positioning bar 203h, a gear sleeve 203i, a push rod 203j, a fourth spring 203k and a stabilizing sleeve 203l. The second bending plate 203g slides in the second support seat 203f, the positioning bar 203h is fixed at both ends of the second bending plate 203g, the gear sleeve 203i slides in the second bending plate 203g, the push rod 203j is fixed on the top of the gear sleeve 203i, the fourth spring 203k is sleeved on the surface of the push rod 203j, and the stabilizing sleeve 203l is fixed on one side of the second bending plate 203g.

[0061] A first bending block 201f-1 is fixed on the first bending plate 201f, and a second bending block 203g-1 is fixed on the second bending plate 203g.

[0062] The second bending plate 203g is used to perform secondary bending on the aluminum skin 104 so that the edge of the aluminum skin 104 is tightly attached to the bottom of the density board 102. The positioning strip 203h is used to position the second bending plate 203g so that the second bending plate 203g can move stably, and the gear sleeve 203i is meshed with the driving gear 203e.

[0063] When the extrusion column 201g descends and causes the driving gear 203e to rotate, it can drive the gear sleeve 203i to move, so that the gear sleeve 203i further compresses the fourth spring 203k through the push rod 203j, so that the fourth spring 203k can push the second bending plate 203g, so that the second bending plate 203g moves toward the aluminum skin 104.

[0064] The first bending block 201f-1 and the second bending block 203g-1 can be cross-coordinated to prevent the aluminum sheet 104 from being wrinkled during the resetting movement of the first bending plate 201f.

[0065] Specifically, the bending part 203 also includes a sleeve 203m, a positioning rod 203n, a fifth spring 203o and a push block 203p. The sleeve 203m is fixed in the second support seat 203f, the positioning rod 203n slides in the sleeve 203m, the two ends of the fifth spring 203o are respectively fixed to the inner wall of the positioning rod 203n and one side of the push block 203p, the push block 203p is fixed to one side of the sleeve 203m, and a placement groove U is opened on one side of the tooth plate 203a.

[0066] The sleeve 203m is used to support the positioning rod 203n. The end of the positioning rod 203n is inserted into the second bending plate 203g to limit the second bending plate 203g. The fifth spring 203o is in a compressed state. When the tooth plate 203a descends, the placement slot U will move synchronously. When the first bending block 201f-1 moves to the lowest point of its stroke, the placement slot U moves to one side of the end of the positioning rod 203n. Under the push of the fifth spring 203o, the end of the positioning rod 203n enters the placement slot U. At this time, the other end of the positioning rod 203n is away from the second bending plate 203g, thereby releasing the limit on the second bending plate 203g, so that the second bending plate 203g moves toward the aluminum skin 104 under the push of the fourth spring 203k, thereby performing a secondary bending on the aluminum skin 104. The positioning rod 203n is located at one end of the second bending plate 203g and is provided with a telescopic mechanism so that the end of the positioning rod 203n can be partially telescoped.

[0067] Specifically, the reset member 204 includes a fixed seat 204a, a rotating plate 204b and a sixth spring 204c. The fixed seat 204a is fixed to one side of the positioning plate 202d. The rotating plate 204b is hinged in the fixed seat 204a through a rotating shaft. The two ends of the sixth spring 204c are respectively fixed to one side of the rotating plate 204b and the inner wall of the fixed seat 204a.

[0068] The fixing seat 204a is used to support the rotating plate 204b so that the rotating plate 204b can swing, and the sixth spring 204c is in a compressed state to support the rotating plate 204b.

[0069] Specifically, the reset member 204 also includes a seventh spring 204d, an insert block 204e and a top block 204f. The two ends of the seventh spring 204d are respectively fixed to the inner wall of the rotating plate 204b and the inner wall of the insert block 204e. The insert block 204e slides in the rotating plate 204b. The top block 204f is fixed to one side of the second bending plate 203g. A positioning groove V is provided on the top of the top block 204f.

[0070] The seventh spring 204d is in a compressed state. When the top block 204f moves into the first support seat 202a along with the second bending plate 203g, the positioning groove V will move to the bottom of the insertion block 204e. Under the action of the restoring elastic force of the seventh spring 204d, the insertion block 204e can be inserted into the positioning groove V, thereby limiting the top block 204f, so that the second bending plate 203g can stay at the bottom of the density board 102 at this time.

[0071] Example 2, reference Figure 1 to Figure 14 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0072] Specifically, first, glue is evenly applied on the top of the density board 102, and then the density board 102 is moved to the top of the conveying platform 101;

[0073] Secondly, the aluminum sheet 104 is moved to the corresponding position on the top of the density board 102 by the suction plate 201a;

[0074] Then, the driving column 201d drives the suction plate 201a to move downward, so that the aluminum sheet 104 is attached to the top of the density board 102;

[0075] Finally, the conveying platform 101 conveys the density board 102 between the squeezing rollers 105 , so that the density board 102 and the aluminum sheet 104 are closely fitted.

[0076] The present invention has the following beneficial effects:

[0077] When the aluminum sheet 104 is pasted, the aluminum sheet 104 can be used to wrap the front end of the density board 102 without manual wrapping.

[0078] Through the cooperation of the first bending plate 201f and the second bending plate 203g, the aluminum sheet 104 can be squeezed and positioned by the second bending block 203g-1 of the second bending plate 203g during the resetting movement of the first bending plate 201f, so that the aluminum sheet 104 will not wrinkle;

[0079] By limiting the top block 204f through the insert block 204e, the second bending plate 203g will not reset the aluminum sheet 104 immediately after bending, so as to prevent the second bending plate 203g from causing wrinkles on the aluminum sheet 104 during the reset process;

[0080] The design of moving the density board 102 away from the top of the rotating plate 204b to reset the second bending plate 203g can make it easier for the second bending plate 203g and the baffle 202g to process the next density board 102, thereby improving the automation of production.

[0081] During use, when it is necessary to stick aluminum skin 104 on the top of the density board 102, first, brush glue evenly on the top of the density board 102, and then move the density board 102 to the top of the conveying platform 101, so that the conveying platform 101 conveys the density board 102 to the side of the baffle 202g. At this time, the conveying platform 101 stops driving the density board 102, and the driving column 201d drives the suction plate 201a to adsorb the aluminum skin 104, so that the aluminum skin 104 moves to the top of the density board 102.

[0082] At this time, the driving column 201d moves downward, and the driving column 201d drives the suction plate 201a to move downward, so that the aluminum skin 104 is attached to the top of the density board 102. Through the thrust of the first spring 201c, the suction plate 201a can squeeze the aluminum skin 104 to ensure the combination between the aluminum skin 104 and the density board 102. In the process of the driving column 201d moving downward, the extrusion column 201g squeezes the baffle 202g downward, so that the baffle 202g will not hinder the first bending plate 201f from bending the aluminum skin 104 for the first time.

[0083] When the first bending plate 201f moves downward, the squeezing column 201g can squeeze the pressing block 203b downward, so that the pressing block 203b moves downward. At this time, the pressing block 203b can drive the tooth plate 203a to move downward, so that the connecting gear 203d drives the driving gear 203e to rotate through the rotating shaft 203c. When the driving gear 203e rotates, it can drive the gear sleeve 203i to move, so that the gear sleeve 203i further compresses the fourth spring 203k through the push rod 203j. When the tooth plate 203a descends, the fourth spring 203k is released. The placement slot U will move synchronously. When the first bending block 201f-1 moves to the lowest point of its stroke, the placement slot U moves to one side of the end of the positioning rod 203n. Under the push of the fifth spring 203o, the end of the positioning rod 203n enters the placement slot U. At this time, the other end of the positioning rod 203n is away from the second bending plate 203g, thereby releasing the limit on the second bending plate 203g, so that the second bending plate 203g moves toward the direction of the aluminum skin 104 under the push of the fourth spring 203k, thereby performing a secondary bending on the aluminum skin 104.

[0084] When the top block 204f moves into the first support seat 202a along with the second bending plate 203g, the positioning groove V will move to the bottom of the insertion block 204e. Under the action of the restoring elastic force of the seventh spring 204d, the insertion block 204e can be inserted into the positioning groove V, thereby limiting the top block 204f, so that the second bending plate 203g can stay at the bottom of the density board 102 at this time.

[0085] At this time, the driving column 201d drives the first bending plate 201f to rise, and then the conveying platform 101 conveys the density board 102, so that the extrusion roller 105 extrudes the bonded density board 102 and the aluminum skin 104, so that the density board 102 and the aluminum skin 104 are tightly combined. When the density board 102 moves away from the top of the rotating plate 204b, the rotating plate 204b loses the extrusion of the density board 102. Under the action of the reset elastic force of the seventh spring 204d, the rotating plate 204b can drive the insert block 204e away from the positioning groove V, thereby releasing the limit on the top block 204f. At this time, the second bending plate 203g can be reset and moved. At the same time as the second bending plate 203g moves, the pressing block 203b can release the extrusion of the baffle 202g, so that the baffle 202g is reset and moved under the action of the reset elastic force of the third spring 202j, thereby facilitating the processing of the next density board 102.
