Description

Technical Field

[0001] This utility model relates to the field of MDF cold pressing technology, specifically to a MDF cold pressing and shaping anti-warping device. Background Technology

[0002] Cold pressing of MDF is an important step in the processing of MDF. It mainly involves applying pressure to the glued MDF at room temperature using a cold press to bond, flatten, and shape it.

[0003] Existing technology discloses a PCB depaneling machine anti-warping device (publication number CN222521483U), comprising a base, support platforms, a pressing mechanism, and a moving mechanism. Two support platforms are symmetrically arranged on top of the base, with a cutting gap between them. Two pressing mechanisms are also symmetrically arranged on top of the two support platforms, each including a mounting frame, a pushing device, and a pressure plate. The pushing device is mounted on the mounting frame, and the pressure plate is located at the bottom of the pushing device, used to press and fix the PCB against the support platforms. The opposing surfaces of the two pressure plates are aligned with the opposing surfaces of the two support platforms. The moving mechanism is located between the support platforms and the base, used to adjust the distance between the support platforms. This PCB depaneling machine anti-warping device provides support and fixation near the cutting section, making it less likely for the PCB to warp.

[0004] The aforementioned pressure plate is located at the bottom of the pusher device. When replacing the pressure plate, it is necessary to cut the pressure plate and the pusher device, which can easily cause damage to the pressure plate and the pusher device, and requires a lot of time to repair the pressure plate and the pusher device.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A cold-pressing and anti-warping device for MDF includes an extrusion device 1 and a metal frame 2. A shaping shell 5 is installed on the bottom surface of the metal frame 2. A cold-pressing plate 4 is slidably connected to the bottom of the shaping shell 5. An electric push rod 3 is installed on the top surface of the cold-pressing plate 4. The extrusion device 1 is installed on the top of the metal frame 2.

[0029] The extrusion device 1 includes a variable frequency motor 11, a bidirectional threaded rod 12, a stamping assembly 13, and a metal slide rod 14. The metal slide rod 14 is slidably connected to the top of the stamping assembly 13 and inserted into the top of the metal frame 2. There are two metal slide rods 14, which are distributed front and back. The metal slide rods 14 can make the movement of the stamping assembly 13 more stable. The bidirectional threaded rod 12 is threadedly connected to the top of the stamping assembly 13 and is installed on the right side surface of the rotor of the variable frequency motor 11.

[0030] The stamping assembly 13 includes an adjustment unit and a stamping unit, which are arranged sequentially from top to bottom.

[0031] The stamping unit includes an extrusion plate 136, a metal lug 137 fixedly connected to the top of the extrusion plate 136, a metal vertical rod 131 fixedly connected to the top surface of the metal lug 137, a connector 138 threadedly connected to the top surface of the extrusion plate 136, and an electric push rod 135 threadedly connected to the top surface of the connector 138.

[0032] The adjustment unit includes a connecting cover plate 132. A threaded rod 133 is fixedly connected to the bottom surface of the connecting cover plate 132, and a threaded rod 133 is installed on the top surface of the connecting cover plate 132. The connecting cover plate 132 is slidably connected to the surface of four metal vertical rods 131 arranged in a rectangular pattern. The metal vertical rods 131 drive the extrusion plate 136 downwards via metal lugs 137, maintaining the stability of the extrusion plate 136. A connecting screw 134 is inserted into one inward end of the connecting cover plate 132. The connecting cover plate 132 is threadedly connected to the surface of a bidirectional threaded rod 12, which is installed on the top of the metal frame 2. A variable frequency motor 11 is installed on the left side surface of the metal frame 2. 1. It can drive the bidirectional threaded rod 12 to rotate, thereby adjusting the left and right movement of the plug screw 134 and adjusting the position of the electric push rod 135. A connecting plate 139 is installed on the top surface of the connecting cover plate 132. The connecting cover plate 132 is slidably connected to the surface of the metal slide rod 14, and the connecting plate 139 is slidably connected to the surface of the metal slide rod 14. The connecting cover plate 132 and the connecting plate 139 are locked and fixed by the threaded rod 133, which facilitates the disassembly and replacement of the connecting cover plate 132 and the connecting plate 139. The connecting plate 139 is installed on the top surface of the electric push rod 135. The electric push rod 135 can push the extrusion plate 136 downward through the connector 138, which can perform stamping operations on the MDF and prevent the ends of the MDF from warping.

[0033] In use, rotating the nut causes it to rotate on the surface of the threaded rod 133, disengaging the nut from the threaded rod 133. This allows the connecting cover plate 132 and the connecting plate 139 to be separated, and the connecting plate 139 and the electric push rod 135 to be replaced.

[0034] Place the glued MDF board at the bottom of the molded outer shell 5, with the MDF board passing directly under the metal frame 2, and positioned below the cold-pressed plate 4.

[0035] Start the variable frequency motor 11. The rotor of the variable frequency motor 11 drives the bidirectional threaded rod 12 to rotate. The bidirectional threaded rod 12 drives the electric push rod 135 to move inward through the connecting cover plate 132 and the connecting plate 139.

[0036] When the connecting cover plate 132 and the connecting plate 139 move on the surface of the bidirectional threaded rod 12, the metal slide bar 14 can maintain the stability of the connecting cover plate 132 and the connecting plate 139, making the movement of the connecting cover plate 132 and the connecting plate 139 smoother.

[0037] The electric push rod 135 can drive the extrusion plate 136 to move, so that the extrusion plate 136 is located directly above both ends of the MDF.

[0038] When the electric push rod 135 is activated, it drives the extrusion plate 136 to move downward through the connector 138. The extrusion plate 136 can drive the metal vertical rod 131 to move downward through the metal lug 137. The metal vertical rod 131 slides on the outward end of the connecting cover plate 132, which can maintain the stability of the extrusion plate 136.

[0039] Next, start the electric push rod 23. The piston rod inside the electric push rod 23 pushes the cold pressing plate 4 downward, so that the cold pressing plate 4 performs cold pressing on the bonded MDF.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
