Description

Technical Field

[0001] This utility model relates to the field of laminating hot press technology, specifically to a sheet positioning mechanism for a laminating hot press. Background Technology

[0002] The hot press for veneer panels is suitable for medium-sized furniture factories or small-scale artificial board secondary processing factories. It includes hot press veneer machines, double-veneer hot press machines, and single-veneer hot press machines. Features include rapid heating of the hot pressing system, carefully segmented design of the heating and heat conduction systems, low energy consumption, uniform heat conduction, reasonable structural layout, high precision of parts processing, wide range of process parameter adjustment, and reasonable control process design. It can meet the process requirements of various veneer production and can be used for hot pressing and bonding furniture panels, building partitions, wooden doors, and various artificial boards.

[0003] When using a current panel hot press, the panel is placed inside the machine, and the operator places the board on top of the panel. The operator manually adjusts the position of the board to make it overlap with the panel, controls the operation of the hot press, and the heating device inside the hot press heats the panel. At the same time, the pressure block inside the hot press moves downward to fix the board and the heated panel together.

[0004] Traditional hot presses for panel lamination fix the veneer and the board together by heating and pressing. Because the hot presses for panel lamination are not equipped with a positioning mechanism, the board moves and misaligns under pressure, resulting in the veneer and the board not being neatly bonded, thus reducing the pass rate of the processed board. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a board positioning mechanism for a veneer hot press. This solves the problem that in traditional veneer hot presses, the veneer and board are fixed together by heating and pressing. Because the veneer hot press lacks a positioning mechanism, the board moves and becomes misaligned under pressure, resulting in an uneven bond between the veneer and the board, thus reducing the pass rate of the processed board.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sheet metal positioning mechanism for a veneer hot press, comprising a main body, wherein a positioning device is provided on the inner wall of the main body, the positioning device comprising: a cylinder detachably connected to the inner wall of the main body; a horizontal plate detachably connected to the output end of the cylinder; two connecting rods, each rotatably connected to the outer wall of the horizontal plate via pins; two vertical plates, each rotatably connected to the outer wall of the two connecting rods via pins and movably connected to the inner wall of the main body; two bent rods, each mounted on the top of the two vertical plates and movably connected to the inner wall of the main body; and two clamping plates, each mounted on the outer wall of the two bent rods; wherein the cylinder drives the vertical plates on the outer side of the connecting rods to move via the horizontal plate, and the vertical plates drive the clamping plates to move inward via the bent rods.

[0007] Preferably, the outer wall of the main body of the device is fitted with a housing, the top of the housing is fitted with a top frame, the outer wall of the housing is fitted with a feeding plate, and the inner wall of the top frame is fitted with multiple plates.

[0008] Preferably, a pressing device is installed on the top of the main body of the device, and a pressure plate is installed on the bottom of the pressing device.

[0009] Preferably, the inner wall of the housing is provided with a feeding device, which includes: a servo motor detachably connected to the outer wall of the housing; a rotating rod detachably connected to the output end of the servo motor and rotatably connected to the inner wall of the housing via a bearing; a round rod installed on the inner wall of the rotating rod; a rotating plate movably connected to the outer wall of the round rod and rotatably connected to the inner wall of the housing via a pin; a sliding rod movably connected to the inner wall of the rotating plate; a straight plate installed on the outer wall of the sliding rod and movably connected to the inner wall of the housing; a spring installed on the inner wall of the straight plate; an inclined plate movably connected to one end of the spring and movably connected to the inner wall of the straight plate, the inclined plate being in contact with the outer wall of the bottom plate; and a sliding part installed on the top of the housing; wherein, when the servo motor is working, it drives the round rod to rotate via the rotating rod, the round rod drives the straight plate on the sliding rod to move via the rotating plate, and the straight plate drives the inclined plate to move.

[0010] Preferably, the sliding part includes: multiple side plates, all mounted on the top of the housing; multiple rollers, all rotatably connected to the outer walls of the multiple side plates via bearings, and in contact with the outer wall of the bottom plate; wherein, the rollers rotate when the plate moves, facilitating the outward movement of the plate.

[0011] This utility model provides a sheet positioning mechanism for a veneer hot press. It has the following advantages: With this sheet positioning mechanism, the sheet moves to the top of the main body of the device, and the extrusion device moves the pressure plate downwards. The pressure plate, in conjunction with the main body of the device, extrudes the sheet. The positioning device positions the sheet, preventing it from shifting under pressure, resulting in a neater bond between the veneer and the sheet, thus improving the pass rate of the processed sheet.

[0012] Multiple boards are placed inside the top frame, and the boards are slowly lowered to the top of the main body of the device by a feeding device. This eliminates the need for workers to move the boards each time, thus reducing their workload. The sliding part reduces friction between the boards and the housing, making it easier for the boards to move. Attached Figure Description

[0018] 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.

[0019] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0020] Traditional hot presses for panel bonding use heat and extrusion to fix the veneer and the board together. Because the hot presses for panel bonding do not have a positioning mechanism, the board moves and misaligns under pressure, resulting in the veneer and board not being neatly bonded together, thus reducing the pass rate of the processed board.

[0021] In view of this, the present invention provides a plate positioning mechanism for a veneer hot press. The plate moves to the top of the main body of the device, and the extrusion device drives the pressure plate to move downward. The pressure plate and the main body of the device extrude the plate. The positioning device positions the plate so that it will not move when it is extruded, making the veneer and the plate more neat after bonding, thereby improving the pass rate of the plate after processing.

[0022] Example 1: By Figure 1 , 2 As shown in sections 3 and 4, a sheet metal positioning mechanism for a veneer hot press includes a main body 1. A positioning device 2 is provided on the inner wall of the main body 1. The positioning device 2 includes: a cylinder 21 detachably connected to the inner wall of the main body 1; a horizontal plate 22 detachably connected to the output end of the cylinder 21; two connecting rods 23, each rotatably connected to the outer wall of the horizontal plate 22 via pins; two vertical plates 24, each rotatably connected to the outer wall of the two connecting rods 23 via pins and movably connected to the inner wall of the main body 1; two bent rods 25, each installed on the top of the two vertical plates 24 and movably connected to the inner wall of the main body 1; and two clamping plates 26, each installed on the outer wall of the two bent rods 25. The cylinder 21 drives the vertical plates 24 outside the connecting rods 23 to move via the horizontal plate 22, and the vertical plates 24 drive the clamping plates 26 to move inward via the bent rods 25.

[0023] In the specific implementation process, it is worth noting that the model of cylinder 21 is SCA2-CB-100B-300-T0H3-DY. When cylinder 21 is working, it drives the connecting rod 23 to move through the horizontal plate 22. The connecting rod 23 drives the clamping plate 26 on the bent rod 25 to move inward through the vertical plate 24.

[0024] Furthermore, a housing 3 is installed on the outer wall of the main body 1, a top frame 5 is installed on the top of the housing 3, a feeding plate 6 is installed on the outer wall of the housing 3, and multiple plates 7 are provided on the inner wall of the top frame 5.

[0025] In the specific implementation process, it is worth noting that the feeding plate 6 facilitates the movement of the sheet material 7 to the top of the device body 1;

[0026] Furthermore, a pressing device 8 is installed on the top of the main body 1 of the device, and a pressure plate 9 is installed on the bottom of the pressing device 8.

[0027] In the specific implementation process, it is worth noting that the extrusion device 8 is existing technology and the model is not specifically limited. The extrusion device 8 drives the pressure plate 9 to move downward.

[0028] Specifically, when using the sheet positioning mechanism of the laminating hot press, the cylinder 21 drives the horizontal plate 22 to move downward, the horizontal plate 22 drives the connecting rod 23 to move inward, the connecting rod 23 drives the vertical plate 24 to move inward, the vertical plate 24 drives the clamping plate 26 on the bent rod 25 to move inward, the clamping plate 26 positions the sheet 7, the feeding plate 6 facilitates the sheet 7 to move to the top of the device body 1, and the extrusion device 8 cooperates with the pressure plate 9 to fix the sheet 7 and the laminating together.

[0029] Example 2: From Figure 1 , 2 As can be seen from points 3 and 4, the inner wall of the housing 3 is provided with a feeding device 4, which includes: a servo motor 41, detachably connected to the outer wall of the housing 3; a rotating rod 42, detachably connected to the output end of the servo motor 41, and rotatably connected to the inner wall of the housing 3 via a bearing; a round rod 43, installed on the inner wall of the rotating rod 42; a rotating plate 44, movably connected to the outer wall of the round rod 43, and rotatably connected to the inner wall of the housing 3 via a pin; a sliding rod 45, movably connected to the inner wall of the rotating plate 44; and a straight plate 46, installed on the sliding rod 45. The outer wall of the rod 45 is movably connected to the inner wall of the housing 3; the spring 47 is installed on the inner wall of the straight plate 46; the inclined plate 48 is movably connected to one end of the spring 47 and is movably connected to the inner wall of the straight plate 46, and the inclined plate 48 is in contact with the outer wall of the bottom plate 7; the sliding part 49 is installed on the top of the housing 3; wherein, when the servo motor 41 works, it drives the round rod 43 to rotate through the rotating rod 42, the round rod 43 drives the straight plate 46 on the sliding rod 45 to move through the rotating plate 44, and the straight plate 46 drives the inclined plate 48 to move;

[0030] In the specific implementation process, it is worth noting that the model of the servo motor 41 is SM80-D601930. The servo motor 41 drives the round rod 43 to rotate through the rotating rod 42. The round rod 43 drives the sliding rod 45 to move through the rotating plate 44. The sliding rod 45 drives the inclined plate 48 inside the straight plate 46 to move. The sliding part 49 facilitates the movement of the plate 7 to the top of the device body 1.

[0031] Specifically, based on the above embodiment one, when the servo motor 41 is working, it drives the rotating rod 42 to rotate, the rotating rod 42 drives the round rod 43 to rotate, the round rod 43 drives the sliding rod 45 to move through the rotating plate 44, the sliding rod 45 drives the inclined plate 48 inside the straight plate 46 to move towards the lower material plate 6, the inclined plate 48 pushes the plate 7 through the lower material plate 6 to the top of the device body 1, eliminating the need for workers to move the plate 7, reducing the workload of workers. When the inclined plate 48 moves in the opposite direction, the inclined plate 48 is squeezed downward by the plate 7, compressing the spring 47. When the inclined plate 48 moves to the side away from the lower material plate 6, the spring 47 in the compressed state helps the inclined plate 48 to return to its original position, and the inclined plate 48 adheres to the outer wall of the plate 7.

[0032] Example 3: From Figure 1 , 2 As can be seen from points 3 and 4, the sliding part 49 includes: multiple side plates 491, all mounted on the top of the housing 3; multiple rollers 492, all rotatably connected to the outer wall of the multiple side plates 491 via bearings, and in contact with the outer wall of the bottom plate 7; wherein, when the plate 7 moves, the rollers 492 rotate, which facilitates the outward movement of the plate 7;

[0033] In the specific implementation process, it is worth noting that when the plate 7 moves, the roller 492 rotates, which reduces the friction force on the plate 7 and makes it easier for the plate 7 to move outward.

[0034] Specifically, based on the above embodiment 1, the roller 492 rotates when the plate 7 moves, reducing the friction force on the plate 7 when it moves, making it easier for the plate 7 to move outward.

[0035] 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 these 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.
