Description

Technical Field

[0001] The utility model relates to the technical field of hot presses, in particular to a plywood hot press. Background Art

[0002] Plywood is a three-layer or multi-layer plate material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them together with adhesive. Usually, an odd number of veneers are used, and the fibers of adjacent veneers are glued perpendicular to each other. Plywood is one of the commonly used materials for furniture and one of the three major types of man-made boards. It can also be used as material for airplanes, ships, trains, cars, buildings, and packaging boxes. The slabs are made by criss-crossing the glue-coated veneers in the direction of the wood grain, and are pressed under heating or non-heating conditions. A hot press is required to make plywood.

[0003] The existing hot press has the following main drawbacks: when pressing plywood, the heating effect is poor and the heating is uneven, which makes the pressing effect of the plywood poor and prone to cracking and delamination. In addition, when loading and unloading, manual loading and unloading are often used. When taking the plywood that has just been pressed, it is easy to get burned, causing safety accidents. At the same time, manual labor also has the problem of low efficiency. Utility Model Content

[0033] Some embodiments of the present invention are described below in conjunction with the accompanying drawings. Figure 1-5 , including: a main body module 100, a heating module 200 and a loading module 300.

[0034] The main module 100 includes a base 110, a support plate 120 fixed to the top of the base 110, an extrusion assembly 130 installed at the bottom of the support plate 120, a feed belt 140 arranged on one side of the base 110, a discharge belt 150 arranged on one side of the base 110 and perpendicular to the feed belt 140, and an ejection assembly 160 arranged at the top of the base 110. The base 110 is used to play a supporting role to maintain the stability of the plywood during pressing. The support plate 120 is in an inverted L shape and is integrally welded to the top edge of the base 110 for installing the extrusion assembly 130. The extrusion assembly 130 includes a plurality of first telescopic rods 131 installed at the bottom of the support plate 120 and an extrusion plate 132 installed at the end of the telescopic rod. The bottom end of the first telescopic rod 131 is fixed to the bottom end of the support plate 120, and the top end is fixed to the top end of the extrusion plate 132. There are at least four first telescopic rods 131 to ensure the pressure when the plywood is pressed.

[0035] The feeding belt 140 is arranged on one side of the base 110, and is used to feed the unpressed plywood to the bottom end of the loading module 300. The discharging belt 150 is perpendicular to the feeding belt, and is used to send out the pressed plywood, thereby improving production efficiency. A rectangular groove 111 is opened at the top of the base 110, and the ejection assembly 160 is arranged below the rectangular groove 111 and extends upward from the rectangular groove 111. The ejection assembly 160 includes a second telescopic rod 162 arranged in the base 110 and an ejection plate 161 fixed at the top of the second telescopic rod 162. The second telescopic rod 162 rises and drives the ejection plate 161 to rise, so as to eject the pressed plywood, thereby avoiding manual operation and increasing safety.

[0036] The heating module 200 includes a steam controller 210 installed on the outer surface of the main module 100, a first heating tube 220 arranged in the inner cavity of the main module 100, and a second heating tube 230 arranged in the main module 100 and below the first heating tube 220. The steam controller 210 is fixed to the bottom end of the outer side surface of the base 110, and is used to control the flow of steam, thereby controlling the temperature of the first heating tube 220 and the second heating tube 230. The first heating tube 220 is arranged in the extrusion plate 132 in an array to increase the heat transfer efficiency. At the same time, the cross-section of the first heating tube 220 is a rectangle with rounded corners, which is convenient for the circulation of steam and increases the area of ​​the heating surface, so that it can heat the plywood more evenly. The second heating tube 230 is installed on the inner wall of the rectangular groove 111, and is used to heat the edge of the plywood to prevent the edge of the plywood from being loosely pressed. The first heating tube 220 and the second heating tube 230 are both connected to the steam controller 210 through a hose.

[0037] The loading module 300 includes a motor 310 installed on the inner bottom wall of the main module 100, a cylinder 320 fixed on the shaft of the motor 310, a disc 330 sleeved and fixed on the outer side of the cylinder 320, and a clamping assembly 340 symmetrically arranged on the disc 330. The motor 310 is fixed on the inner bottom wall of the base 110 and faces upward. The bottom end of the cylinder 320 is fixed on the shaft of the motor 310, and the top end extends out of the base 110, so that the rotation of the motor 310 can drive the cylinder 320 to rotate. The disc 330 is sleeved and fixed on the outer side of the part of the cylinder 320 extending out of the base 110. The clamping assembly 340 is symmetrically mounted on the disc 330 and includes a double-headed push rod 341 disposed in the disc 330, a clamping rod 342 symmetrically fixed to the end of the double-headed push rod 341, and a protrusion 343 disposed on the outer surface of the clamping rod 342. The clamping rod 342 is L-shaped, and its end is fixed to the end of the double-headed push rod 341, so that the double-headed push rod 341 drives the clamping rod 342 to extend and retract when extending and retracting, thereby clamping the plywood. The cross-section of the protrusion 343 is triangular, which is used to maintain the stability of the clamping rod 342 when clamping.

[0038] The working principle and use process of the utility model are as follows: when it is necessary to press the plywood, the unpressed plywood is placed on the feeding belt 140, the clamping assembly 340 starts to work, the double-headed push rod 341 retracts, driving the clamping rod 342 to retract, so that the clamping rod 342 fixes the plywood, and at this time the motor 310 rotates to move the plywood above the rectangular groove 111, the clamping assembly 340 releases the twisted plate, the extrusion assembly 130 starts to descend, and at the same time the steam controller 210 controls the steam to circulate in the first heating tube 220 and the second heating tube 230 to quickly heat the plywood, and when the pressing is completed, the extrusion assembly 130 rises, the ejection assembly 160 ejects the pressed plywood, the clamping assembly 340 contracts again to clamp the plywood, the motor 310 rotates, and when the plywood rotates to above the discharge belt 150, the clamping assembly 340 is released, so that the pressed plywood is sent out by the discharge belt 150.
