Description

Technical Field

[0001] The utility model relates to the technical field of plywood production, in particular to a plywood shaping cold pre-pressing machine. Background Art

[0002] Cold pressing is an important step in the production and shaping of plywood. Plywood is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them with adhesives. In the production and shaping of plywood, cold pressing is required to make the veneers tightly bonded and form a good overall structure. Cold pressing can make the plywood tightly bonded together by external pressure without heat, forming a stable board structure.

[0003] The existing Chinese patent with announcement number CN215038336U discloses a cold press machine for plywood production, including a loading table and a cold press table. A support frame is installed on the upper surface of the cold press table. Two cold press cylinders are fixedly connected to the upper surface of the support frame, and the output ends of the two cold press cylinders extend to the lower surface of the support frame and are fixedly connected to a cold press template. The limit plate can limit the edge of the plywood, and the cold press template drives the limit plate to extrude downward, which can ensure that the edge of the plywood will not be separated from the glue or unevenly extruded when being extruded, thereby improving the cold pressing quality of the plywood.

[0004] Based on the above situation, the inventors believe that currently, cold pre-pressing of plywood is often carried out by stacking cold pressing, and the current cold pre-pressing machine stacking operation often requires workers to visually limit and align the edges of the panels, which makes it difficult to improve operational convenience and stacking accuracy.

DETAILED DESCRIPTION

[0038] The technical solution of the utility model will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] The utility model embodiment specifically provides a plywood shaping cold pre-pressing machine, please refer to Figure 1 , including a body 1, an axle frame 2, a stopper 3, an installation compartment 4, a groove 5 and a driving assembly 6.

[0040] Among them, the machine body 1 includes a machine base 11 and a cold pressing component 12 fixed on the upper surface of the machine base 11, the shaft frame 2 is arranged at the front end of the machine base 11 in a left-right symmetrical manner, the outer side of the block 3 is connected to the shaft frame 2, and the block 3 is used to limit the position of the wooden board to be cold pressed so that the front end of the wooden board can be kept flush when the wooden board is stacked, which is convenient for workers to align the wooden boards. Two installation bins 4 distributed symmetrically on the left and right are fixed on the front side of the machine base 11, and a groove 5 is formed adjacent to the outer side of the installation bin 4 and the front side of the machine base 11, and the groove 5 provides space for the subsequent downward displacement of the shaft frame 2.

[0041] Among them, the bottoms of the two shaft frames 2 are respectively connected to the first driven mechanism and the second driven mechanism, and the first driven mechanism and the second driven mechanism are connected through a transmission assembly. The driving assembly 6 is arranged on the installation bin 4, and the driving assembly 6 drives one of the shaft frames 2 to rotate through the first driven mechanism, and the other shaft frame 2 rotates in the opposite direction through the second driven mechanism and the transmission assembly to drive the block 3 to move out of the operating range of the cold pressing assembly 12.

[0042] During implementation, the downward projection of the blocker 3 falls within the groove 5, so that the setting height of the blocker can be close to the bottom height of the cold pressing plate of the cold pressing assembly 12, thereby maximizing the convenience of front end alignment operation when stacking wooden boards, and allowing the blocker 3 to have space to move downward when the cold pressing plate is pressed down.

[0043] For further information, please refer to Figure 2 The shaft frame 2 includes a rotating shaft 21 whose bottom end is rotatably arranged on the installation bin 4 and a bracket 22 whose one end is fixedly connected to the outer side of the rotating shaft 21. The other end of the bracket 22 is connected to the stopper 3, so that when the two rotating shafts 21 expand and rotate outward, the stopper 3 can be driven to be lowered and moved out from the cold pressing assembly 12, so as to facilitate the cold pressing assembly 12 to move downward to press the plywood.

[0044] Specifically, the stopper 3 includes a stopper tube 31, a rolling assembly 32 arranged at the top of the stopper tube 31, and an elastic assembly installed inside the stopper 3. During daily use, the front end of the plywood is fitted by the two stopper tubes 31 to facilitate the front end of the plywood to maintain the same horizontal plane. The top of the rolling assembly 32 rolls with the cold press plate of the cold press assembly 12 to facilitate the top end of the stopper tube 31 to slide out on the bottom surface of the cold press plate through the rolling assembly 32 when the cold press plate moves downward.

The outer wall of the rolling ball 321 rolls in contact with the seat plate 322 and the rolling opening 323, so that the retaining tube 31 can move outward quickly when it contacts the cold pressing plate.

[0046] The inner diameter of the rolling opening 323 is smaller than the outer diameter of the rolling ball 321 , so that the top of the rolling ball 321 can be exposed through the rolling opening 323 to the upper surface of the retaining tube 31 and then contact and roll with the cold pressing plate.

[0047] Please refer to Figure 5 The elastic component includes a sliding column 331 which is arranged to slide up and down in the retaining tube 31, a spring 332 whose bottom end is fixed to the sliding column 331, and a support 333 which is fixedly connected to the inner wall of the retaining tube 31. The outer side of the sliding column 331 is in sliding contact with the inner wall of the retaining tube 31, and the support 333 is fixed to the top of the spring 332, so that when the retaining tube 31 is subjected to force, it can move downward, so that the support 333 presses the spring 332 to obtain the elastic force to drive the retaining tube 31 to move upward.

[0048] During implementation, a guide rail 34 is provided on one side of the retaining tube 31 close to the shaft frame 2, the outer end of the bracket 22 is fixed to the sliding column 331, and the outer side of the bracket 22 is slidably matched with the guide rail 34, so that when the rotating shaft 21 rotates, the sliding column 331 is driven to rotate synchronously through the bracket 22, so that the retaining tube 31 can complete the rotation and be lowered, removed or reset from the cold press plate.

[0049] For further information, please refer to Figure 1 and Figure 3The driving assembly 6 includes a motor 61 fixed to the upper surface of the mounting chamber 4 and a driving gear 62 whose center is fixed to the output shaft of the motor 61. The driving gear 62 is located in the mounting chamber 4, and the driving gear 62 is connected to the first driven mechanism, so that after the motor 61 drives the driving gear 62 to rotate, it can drive the first driven mechanism to rotate synchronously, so as to first drive one of the rotating shafts 21 to rotate.

[0050] The connecting chamber 7 is fixedly mounted at the bottom of the inner side of the groove 5, and the interior of the mounting chamber 4 is communicated with the connecting chamber 7 through the through opening 41. The first driven mechanism includes a synchronization rod 81 fixedly connected to one of the rotating shafts 21 at the top and a first driven gear 82 coaxially fixed to the synchronization rod 81. The outer side of the first driven gear 82 is meshed with the driving gear 62, so that when the driving gear 62 rotates, the synchronization rod 81 can be driven to rotate through the first driven gear 82, so that the rotating shaft 21 rotates.

[0051] The second driven mechanism includes a driving rod 91 fixed to another rotating shaft 21 at the top, a driving gear 92 coaxially fixed on the driving rod 91, and a second driven gear 93 meshing with the driving gear 92 on the outside. A transmission rod 94 is fixed to the center of the bottom side of the second driven gear 93. The second driven gear 93 cooperates with the transmission assembly through the transmission rod 94, so that the rotation force on the synchronization rod 81 can be transmitted to the second driven gear 93 through the transmission assembly, and the rotation of the second driven gear 93 drives the driving gear 92 and the first driven gear 82 to rotate in the opposite direction, so that the two rotating shafts 21 can rotate in opposite directions, so as to respectively drive the retaining tube 31 thereon to rotate outward or reset under the cold press plate;

[0052] Among them, the transmission assembly includes two transmission wheels 101 respectively fixed to the bottom end of the synchronization rod 81 and the outer side of the transmission rod 94. The two transmission wheels 101 are rotated together through a transmission belt 102. The transmission belt 102 is located inside the installation compartment 4, the through port 41 and the connection compartment 7, so that the synchronization rod 81 and the transmission rod 94 can rotate synchronously to meet the transmission needs of the reversal of the two rotating shafts 21.

[0053] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.
