Cold pressing equipment for the production of solid wood doors

Abstract

The present invention relates to the technical field of cold presses, and specifically to a cold pressing device for the production of solid wood doors, including a pressing table, on which a wooden board is placed. In this cold pressing device for the production of solid wood doors, the descending counterweight presses the horizontally placed wooden board to warp it vertically and drop into the detection slot. If the wooden board is narrower than the detection slot and meets the requirements, it can directly fall and be discharged through one of the entrances of the plate frame. If the wooden board is thicker than the detection slot and does not meet the requirements, the thick wooden board will push the counterweight and the U-shaped sliding frame to move backward through the support arm. At this time, the synchronously moving rack pulls the gear and the shaft rod to rotate, causing the two baffles on the shaft rod to shift relative to each other, which can close the aforementioned entrance and open the other entrance, allowing the wooden board to be discharged therefrom. In this way, the thickness of the wooden board is detected, and according to different detection situations, the compliant and non-compliant wooden boards are automatically separated and discharged, facilitating the operator to collect the compliant wooden boards and also facilitating the subsequent reprocessing of the non-compliant wooden boards.

Description

Technical Field

[0001] The present invention relates to the technical field of cold presses, and specifically relates to a cold pressing device for making solid wood doors. Background Technique

[0002] A solid wood door refers to a door made of natural logs or solid wood integrated materials taken from the forest. Generally, the main material of a solid wood door is a log for the door core, which is dried and then processed through processes such as cutting, polishing, mortising, and boring.

[0003] Generally speaking, solid wood doors are divided into two types: the first is log solid wood, and the material is natural logs taken from the forest. There is only one kind of wood in the made product, without veneer or board pasting; the second is solid wood composite, and the material is that the door core is made of Chinese fir or other miscellaneous woods pressed with density boards and then veneered.

[0004] In the process of producing solid wood composite doors, a cold press is needed to press the wooden boards, which can level and shape the furniture and make the bonding between the boards more firm. However, in order to avoid uneven pressing, the surface of the wooden board in contact with the pressing plate needs to be manually cleaned before pressing, and the wooden board also needs to be manually removed after pressing, and the operation is rather inconvenient.

[0005] In view of this, we propose a cold pressing device for making solid wood doors. Summary of the Invention

[0006] The purpose of the present invention is to provide a cold pressing device for making solid wood doors to solve the problem that the surface of the wooden board in contact with the pressing plate needs to be manually cleaned before pressing, and the wooden board also needs to be manually removed after pressing, and the operation is rather inconvenient as mentioned in the above background technique. To achieve the above purpose, the present invention provides the following technical solution: A cold pressing device for making solid wood doors, including a pressing table, and a wooden board is placed on the pressing table. On the left and right sides of the top of the pressing table, side brackets are fixedly installed, and a main bracket is fixedly installed on the tops of the two side brackets. Two hydraulic cylinders are installed on the main bracket, and a pressing plate is fixedly connected to the telescopic rods at the bottoms of the two hydraulic cylinders.

[0008] Preferably, the cleaning component includes guide rails fixedly arranged on the top of the pressing table. The number of the guide rails is two, and the two guide rails are respectively located on the left and right sides of the pressing table and are symmetrically distributed. A sliding beam is slidably connected to the two guide rails.

[0009] A scraping strip for cleaning the wooden board is arranged at the bottom of the sliding beam, and a board unloading member is arranged on the scraping strip.

[0010] Both ends of the sliding beam are fixedly connected with steel cables, and the number of the steel cables is four. The four steel cables are equally divided into two groups, and a single group of steel cables is symmetrically arranged on the front and rear sides of the end of the sliding beam.

[0011] The front and rear ends of the guide rail are both provided with gaps connected to the interior thereof, and wire wheels are rotatably connected in the gaps, and wire wheels corresponding to the steel cables are also rotatably installed on the front and rear sides of the surfaces of the side brackets on both sides.

[0012] The two steel cables on the front side are respectively passed around two wire wheels on the same side to be fixedly connected with the pressing plate.

[0013] Two U-shaped slides are arranged on the rear side of the press table.

[0014] A counterweight block is vertically slidably connected between the two U-shaped slides, and the two steel cables at the rear side are respectively passed around two wire wheels on the same side to be fixedly connected with the counterweight block.

[0015] Preferably, the plate unloading member includes a groove at the bottom of the sliding beam, the scraper strip is slidably connected in the groove, and a spring is arranged between the groove and the scraper strip, the spring pushes the scraper strip downward with the sliding beam as the base point, and the bottom of the scraper strip is cut into an inclined surface facing the front side.

[0016] A detection component for detecting the unloaded wooden board is arranged between the two U-shaped slides and the press table.

[0017] Preferably, the detection member comprises two sleeves fixedly mounted on the side surface of the press platform, and the two sleeves are symmetrically arranged along the left and right sides of the press platform.

[0018] The side surfaces of the two U-shaped slides are fixedly connected with support arms, and the two groups of support arms are respectively slidably inserted in the sleeves on the same side.

[0019] A flat plate is fixedly connected to the rear side of the pressing platform surface, and the gap between the flat plate and the counterweight block is set as a detection gap. An opening larger than the width of the wooden board is opened on the surface of the counterweight block, and when the counterweight block moves downward, the horizontally placed wooden board is pressed upright through the opening and falls into the detection gap.

[0020] A plate frame is fixedly connected to the lower side of the flat plate, and an inner wall of the plate frame is rotatably connected to an axis rod along the left and right sides, the axis rod divides the inner side of the plate frame into two entrances, and two baffles are fixedly connected to the surface of the axis rod, one of the baffles is hung downward, and the remaining baffle is inclined upward by 30°.

[0021] An inner hole corresponding to the end of the shaft rod is opened on the inner wall of the plate frame, and the shaft rod rotates in the inner hole and is fixedly sleeved with a gear. A slot connected to the inner hole is opened on the rear side of the plate frame surface, and a rack corresponding to the slot is fixedly connected to the side surface of the U-shaped slide, and the rack is slidably inserted in the slot and meshes with the gear.

[0022] Preferably, balance rods are rotatably connected to the front and rear sides of the top of the pressing plate through brackets. Vertical grooves corresponding to the balance rods are formed on the opposite sides of the surfaces of the two side brackets, and a tooth surface is formed on one side wall of each vertical groove. The two ends of each balance rod extend into the corresponding vertical grooves and are fixedly connected to tooth discs, and the tooth discs are engaged with the corresponding tooth surfaces.

[0023] Preferably, rollers cooperating with the guide rails are rotatably arranged on the upper and lower sides of the end of the sliding beam.

[0024] Preferably, a plate groove is formed in the pressing table, and the inner wall of the plate groove near the side of unloading the plate is cut into a slope.

[0025] Preferably, a bolt seat is arranged on the top of the counterweight block, and the steel cable is fixed to the bolt seat through a bolt.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] In the present invention, when the pressing plate moves downward, the two steel cables on the front side are pulled along the wire wheels, and the sliding beam is pulled forward inside the guide rail. The scraping strip at the bottom of the sliding beam jacks up the back board by using the inclined surface and fits the surface of the board, so as to scrape and remove sundries on its surface, which can effectively avoid the situation that the surface of the board is unevenly pressed, and the operation of the steel cable and the sliding beam and other components will not interfere with the normal operation of the pressing plate.

[0028] In the present invention, the counterweight block uses its own weight to pull the sliding beam to move backward to its original position. Since the back of the scraping strip is not an inclined surface and cannot be jacked up, at this time, the sliding beam uses the scraping strip to push the board backward, so as to unload the board on the pressing table. There is no need for an operator to manually take out the pressed board. On the one hand, it is not easy to cause safety hazards, and on the other hand, the workload can be reduced, and the production efficiency can be improved by more smooth and stable processing.

[0029] In the present invention, the downward moving counterweight block uses the opening on its surface to sleave the tail of the board, and presses the horizontally placed board to be warped to the vertical state as it moves downward. The vertically placed board then falls into the detection slot. If the board is narrower than the detection slot and meets the requirements, it can directly fall and be discharged through one of the entrances of the board frame. If the board is thicker than the detection slot and does not meet the requirements, the thick board will push the counterweight block and the U-shaped sliding frame to move backward through the support arm. At this time, the synchronously moving rack pulls the gear and the shaft rod to rotate, so that the two baffles on the shaft rod shift relative to each other, which can close the aforementioned entrance and open the other entrance, so that the board is discharged therefrom. In this way, the thickness of the board is detected, and according to different detection situations, the compliant and non-compliant boards are automatically separated and discharged, which is convenient for the operator to collect the compliant boards and also convenient for subsequent reprocessing of the non-compliant boards.

Detailed implementation manners

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] Please refer to Figures 1 to 10 , the present invention provides a technical solution: a cold pressing device for making solid wood doors, including a pressing table 1, on which a wooden board is placed. On both the left and right sides of the top of the pressing table 1, side brackets 2 are fixedly installed, and on the top of the two side brackets 2, a main bracket 3 is fixedly installed. Two hydraulic cylinders 4 are installed on the main bracket 3, and on the telescopic rods at the bottoms of the two hydraulic cylinders 4, a pressing plate 5 is fixedly connected. By starting the hydraulic cylinders 4 to push the pressing plate 5 downward, static pressure can be applied to the wooden board.

[0043] A cleaning component 6 is provided on the pressing plate 5, the main bracket 3, and the pressing table 1.

[0044] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 10 shown, the cleaning component 6 includes guide rails 61 fixedly arranged on the top of the pressing table 1, and the number of the guide rails 61 is two. The two guide rails 61 are respectively located on the left and right sides of the pressing table 1 and are symmetrically distributed, and a sliding beam 62 is slidably connected on the two guide rails 61;

[0045] A scraping strip 63 for cleaning the wooden board is arranged at the bottom of the sliding beam 62, and a plate unloading member 64 is arranged on the scraping strip 63;

[0046] Both ends of the sliding beam 62 are fixedly connected with steel cables 65, and the number of the steel cables 65 is four. The four steel cables 65 are equally divided into two groups, and a single group of steel cables 65 is symmetrically arranged on the front and rear sides of the end of the sliding beam 62;

[0047] Notches 66 communicating with the inside are opened at the front and rear ends of the guide rail 61, and wire wheels 67 are rotatably connected in the notches 66. Wire wheels 67 corresponding to the steel cables 65 are also rotatably installed on the front and rear sides of the surfaces of the two side brackets 2;

[0048] The two front steel cables 65 respectively bypass the two wire wheels 67 on the same side and are fixedly connected to the pressing plate 5. During the downward movement of the pressing plate 5, the two front steel cables 65 are pulled along the wire wheels 67 and pull the sliding beam 62 forward inside the guide rail 61 to scrape and sweep its surface to remove debris;

[0049] Two U-shaped sliding frames 68 are arranged at the rear side of the pressing table 1;

[0050] A counterweight 69 is vertically slidably connected between two U-shaped sliding frames 68, and the two steel cables 65 at the rear side respectively bypass the two wire wheels 67 on the same side and are fixedly connected to the counterweight 69.

[0051] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 10 shown, the unloading plate member 64 includes a slot 641 opened at the bottom of the sliding beam 62, the scraping strip 63 is slidably connected in the slot 641, and a spring 642 is provided between the slot 641 and the scraping strip 63. The spring 642 pushes the scraping strip 63 downward with the sliding beam 62 as the base point, and the bottom of the scraping strip 63 is cut into an inclined surface 643 facing the front side. When the pressing plate 5 moves upward after pressing is completed, the front steel cable 65 is released synchronously, so that the counterweight 69 pulls the sliding beam 62 to move backward and return to its position by its own weight. Since the back surface of the scraping strip 63 is not the inclined surface 643 and cannot be lifted, at this time, the sliding beam 62 uses the scraping strip 63 to push the wooden board backward, thereby unloading the wooden board on the pressing table 1;

[0052] A detection member 644 for detecting the unloaded wooden board is provided between the two U-shaped sliding frames 68 and the pressing table 1.

[0053] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 10 shown, the detection member 644 includes two sleeves 6441 fixedly installed on the side surface of the pressing table 1, and the two sleeves 6441 are symmetrically arranged along the left and right sides of the pressing table 1;

[0054] Support arms 6442 are fixedly connected to the side surfaces of the two U-shaped sliding frames 68, and the two groups of support arms 6442 are respectively slidably inserted into the sleeves 6441 on the same side;

[0055] A flat plate 6443 is fixedly connected to the rear side of the surface of the pressing table 1, and the gap between the flat plate 6443 and the counterweight 69 is set as a detection gap 6444. An opening 6445 larger than the width of the wooden board is opened on the surface of the counterweight 69, and when the counterweight 69 moves downward, the horizontally placed wooden board is pressed and warped up through the opening 6445 and falls into the detection gap 6444;

[0056] A frame 6446 is fixedly connected to the lower side of the flat plate 6443, and a shaft rod 6447 is rotatably connected to the inner wall of the frame 6446 along the left and right sides. The shaft rod 6447 divides the inner side of the frame 6446 into two inlets, and two baffles 6448 are fixedly connected to the surface of the shaft rod 6447. One of the baffles 6448 hangs downward, and the remaining baffle 6448 inclines upward by 30°;

[0057] On the inner wall of the plate frame 6446, there is an inner hole 6449 corresponding to the end of the shaft rod 6447. The shaft rod 6447 rotates in the inner hole 6449 and is fixedly sleeved with a gear 64410. On the rear side of the surface of the plate frame 6446, there is a slot 64411 communicating with the inner hole 6449. A rack 64412 corresponding to the slot 64411 is fixedly connected to the side surface of the U-shaped slide 68. The rack 64412 is slidably inserted into the slot 64411 and meshes with the gear 64410. When the thickness of the wooden board is greater than the detection gap 6444 and does not meet the requirements, the thick wooden board will push the counterweight 69 and the U-shaped slide 68 to move backward through the support arm 6442. At this time, the synchronously moving rack 64412 pulls the gear 64410 and the shaft rod 6447 to rotate, so that the two baffles 6448 on the shaft rod 6447 shift relative to each other, closing the aforementioned entrance and opening the other entrance.

[0058] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 10 shown, balance rods are rotatably connected to the front and rear sides of the bottom of the pressing plate 5 through brackets. Vertical grooves corresponding to the balance rods are provided on the opposite sides of the surfaces of the two side brackets 2. One side wall of the vertical groove is provided with a tooth surface. The two ends of the balance rod respectively extend into the corresponding vertical grooves and are fixedly connected with tooth discs, and the tooth discs mesh with the corresponding tooth surfaces. By the rotation of the two tooth discs along the tooth surfaces, the attitude of the pressing plate 5 can be balanced to prevent it from tilting.

[0059] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 10 shown, rollers cooperating with the guide rail 61 are rotatably arranged on the upper and lower sides of the end of the sliding beam 62. The rollers are used for the contact between the sliding beam 62 and the guide rail 61 and reduce the friction when the sliding beam 62 moves, ensuring smooth operation.

[0060] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 10 shown, a plate groove is provided on the pressing table 1, and the inner side wall of the plate groove near the side of unloading the plate is cut into a slope, so that when the sliding beam 62 drives the scraping strip 63 to move forward for cleaning, the wooden board will not be pushed, and when the sliding beam 62 drives the scraping strip 63 to push the wooden board backward, the wooden board can move more easily.

[0061] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 10As shown, a bolt seat is provided at the top of the counterweight 69, and the steel cable 65 is fixed to the bolt seat by bolts. According to the weights of different wooden boards, the operator can conveniently replace the counterweight 69 with the corresponding weight to ensure that the counterweight 69 can push out the wooden board without excessive pushing speed.

[0062] The usage method and advantages of the present invention: When this cold pressing device for solid wood door production is working and in use, the working process is as follows:

[0063] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 10 shown:

[0064] S1. Place the solid wood board along the front side of the equipment into the board groove on the pressing table 1, and then start the hydraulic cylinder 4 to push the pressing plate 5 downward to statically press the board.

[0065] S2. During the downward movement of the pressing plate 5, the two front steel cables 65 are pulled along the wire wheels 67, and the sliding beam 62 is pulled forward inside the guide rail 61. The scraping strip 63 at the bottom of the sliding beam 62 jacks up the back of the board by using the inclined surface 643 and fits the surface of the board to scrape and remove debris on its surface.

[0066] S3. Since the sliding beam 62 will pull up the counterweight 69 along the wire wheels 67 by using the rear steel cable 65 during the forward movement, when the pressing plate 5 moves upward after pressing, the front steel cable 65 is released synchronously, so that the counterweight 69 pulls the sliding beam 62 to move backward to its original position by its own weight. Since the back of the scraping strip 63 is not an inclined surface 643 and cannot be jacked up, at this time, the sliding beam 62 uses the scraping strip 63 to push the board backward to unload the board on the pressing table 1.

[0067] S4. When the board is pushed backward on the pressing table 1 by the sliding beam 62 and the scraping strip 63, the downward moving counterweight 69 sleevs the tail of the board through the surface opening 6445 and presses the horizontally placed board to be warped to the vertical state as it moves downward. The vertically placed board then falls into the detection slot 6444. If the board is narrower than the detection slot 6444 and meets the requirements, it can directly fall and be discharged through one of the entrances of the board frame 6446. If the board is thicker than the detection slot 6444 and does not meet the requirements, the thick board will push the counterweight 69 and the U-shaped sliding frame 68 to move backward through the support arm 6442. At this time, the synchronously moving rack 64412 pulls the gear 64410 and the shaft rod 6447 to rotate, so that the two baffles 6448 on the shaft rod 6447 are displaced from each other to close the aforementioned entrance and open the other entrance, allowing the board to be discharged therefrom.

[0068] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present invention, and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
