Description

Technical Field

[0001] This utility model relates to the field of multi-blade saw technology, specifically a protective structure for multi-blade saws. Background Technology

[0002] In plywood processing, multi-blade saws are mainly used in the pretreatment stage of the substrate. They can accurately cut the raw material into multiple thin veneers of uniform size in one go, laying the foundation for subsequent veneer drying and gluing processes. Compared with traditional single-blade saws, multi-blade saws can complete the cutting of multiple veneers simultaneously, greatly improving the processing efficiency of plywood substrates.

[0003] The multi-blade saw is driven by a motor to rotate the main shaft at high speed, which drives multiple sets of saw blades mounted in parallel on the shaft to operate synchronously. The cutting force of the saw blade teeth is used to cut the wood. During operation, the wood to be processed is fed to the saw blade set at a uniform speed through the feeding mechanism (such as a conveyor belt or push table). The multi-blade saw cuts the wood longitudinally or transversely at a preset interval, and can complete the processing of multiple strips or pieces of wood at one time.

[0004] In existing plywood processing, the board is first placed into the feed inlet of a multi-blade saw and pushed to make contact with the saw blade. However, when the board comes into contact with the high-speed rotating saw blade during the pushing process, there will be reverse resistance, which will generate a rebound force, causing the wood to bounce back in the opposite direction of the push, posing a hazard to the operator.

[0005] Therefore, a protective structure for multi-blade saws is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A multi-blade saw protective structure of this utility model includes a multi-blade saw body, with a saw blade assembly disposed in the middle of the multi-blade saw body; multiple transmission wheels are disposed inside the multi-blade saw body; a feed inlet and a discharge outlet are sequentially opened at the ends of the multi-blade saw body; a feed plate is fixedly connected to the side wall of the feed inlet; multiple screws are rotatably connected to the top of the feed plate; an adjusting block is threadedly connected to the middle of the screws; a motor is fixedly connected to the side wall of the adjusting block; a pressure wheel is fixedly connected to the output end of the motor; multiple guide rods are fixedly connected to the surface of the multi-blade saw body; the guide rods and the adjusting block are slidably connected; by adding a pressure wheel, the plywood can be squeezed first when the plywood is placed, making the plywood and the feed plate fit tightly; subsequently, when the plywood moves, the pressure wheel increases the pushing force on the plywood, so that when resistance is generated, the pushing force of the pressure wheel is eliminated, thereby increasing the protective means when the plywood is being fed.

[0008] Preferably, a fixing frame is fixedly connected to the end of the feed plate; multiple rollers are rotatably connected inside the fixing frame; a pair of cleaning blocks are fixedly connected to the inner wall of the fixing frame; multiple rollers are rotatably connected to the side wall of the cleaning blocks; by adding the fixing frame, the movement path of the plywood can be corrected when the plywood is placed, and at the same time, the side wall of the plywood will be cleaned by the cleaning blocks when the plywood is moving, thereby reducing impurities on the side wall of the plywood.

[0009] Preferably, a pair of connecting plates are fixedly connected to the end of the discharge port; a buffer plate is fixedly connected to the end of the connecting plate; by adding the buffer plate, the plywood can be received when it is taken out after being cut, and the cut plywood is gradually moved down by the slope of the buffer plate, thereby slowing down the falling of the plywood and increasing the time for collecting the plywood.

[0010] Preferably, a fixing block is fixedly connected to the top of the screw; the fixing block and the screw are correspondingly arranged; by adding the fixing block, the rotation speed of the screw can be accelerated when force is applied, making the adjustment of the screw faster.

[0011] Preferably, a baffle is fixedly attached to the surface of the feed plate; multiple baffles are provided on the feed plate; by adding baffles, the screw can be protected during use, reducing the impact caused by the contact between sawdust and the screw.

[0012] Preferably, a friction pad is fixed to the surface of the buffer plate; multiple friction pads are provided on the buffer plate; by increasing the friction pads, the sliding speed of the plywood can be reduced when the plywood slides, thereby reducing the force that causes the plywood to fall off the bottom of the buffer plate.

[0013] The advantages of this utility model are:

[0014] 1. The multi-blade saw protective structure of this utility model, by adding a pressure roller, can first squeeze the plywood when placing it, so that the plywood and the feed plate are in close contact. Then, when the plywood moves, the pressure roller increases the pushing force on the plywood, so that when resistance is generated, the pushing force of the pressure roller is eliminated, thereby adding a protective measure when the plywood is being fed.

[0015] 2. The multi-blade saw protective structure described in this utility model can correct the movement path of the plywood when it is placed by adding a fixing frame. At the same time, when the plywood is moved, the cleaning block will clean the side wall of the plywood, thereby reducing impurities on the side wall of the plywood. Attached Figure Description

Detailed Implementation

[0023] 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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a protective structure for a multi-blade saw includes a multi-blade saw body 1, with a saw blade assembly 11 disposed in the middle of the multi-blade saw body 1; multiple transmission wheels 12 are disposed inside the multi-blade saw body 1; a feed inlet 13 and a discharge outlet 14 are sequentially opened at the ends of the multi-blade saw body 1; a feed plate 15 is fixedly connected to the side wall of the feed inlet 13; multiple screws 16 are rotatably connected to the top of the feed plate 15; an adjusting block 17 is threadedly connected to the middle of the screws 16; the side wall of the adjusting block 17... A motor 18 is fixedly connected; the output end of the motor 18 is fixedly connected to a pressure roller 19; multiple guide rods 101 are fixedly connected to the surface of the multi-blade saw body 1; the guide rods 101 and the adjusting block 17 are slidably connected; during operation, the plywood is first placed on the surface of the feed plate 15. At this time, the height between the pressure roller 19 and the surface of the feed plate 15 is adjusted according to the thickness of the plywood, so that the height between the pressure roller 19 and the feed plate 15 is slightly smaller than the thickness of the plywood. During adjustment, the screw 16 is rotated first, and then... When the machine is in motion, the adjusting block 17 moves via the screw thread, thereby moving the pressure roller 19 on the adjusting block 17. After adjustment, the motor 18 is turned on to rotate the pressure roller 19. At this time, the plywood moves closer to the pressure roller 19. When the plywood comes into contact with the pressure roller 19, it is driven into the multi-blade saw body 1 by the rotation of the pressure roller 19. At the same time, the plywood is squeezed by the pressure roller 19 when it enters. Because the distance between the pressure roller 19 and the feed plate 15 is smaller than the thickness of the plywood, the plywood is squeezed as it moves. When the plywood is in motion, it is squeezed, so that the resistance generated when the plywood comes into contact with the saw blade assembly 11 is eliminated by the forward transmission and squeezing force of the clamping wheel 19, thereby increasing the protection during feeding. By adding the clamping wheel 19, the plywood can be squeezed by the clamping wheel 19 when it is placed, so that the plywood and the feed plate 15 are in close contact. Then, when the plywood moves, the clamping wheel 19 increases the pushing force on the plywood, so that the pushing force of the clamping wheel 19 can eliminate the resistance when it is generated, thereby increasing the protection when the plywood is fed.

[0026] like Figures 1 to 3As shown, a fixed frame 2 is fixedly connected to the end of the feed plate 15; multiple rollers 21 are rotatably connected inside the fixed frame 2; a pair of cleaning blocks 22 are fixedly connected to the inner wall of the fixed frame 2; multiple rollers 23 are rotatably connected to the side wall of the cleaning blocks 22; during operation, when the plywood is placed, it will first move onto the rollers 21, and then gradually move towards the center of the fixed frame 2. During the movement, the end of the plywood will first contact the rollers 23, at which time the rollers 23 will roll to reduce the friction of the plywood on the cleaning blocks 22. Then the two sides will contact the end of the cleaning blocks 22. When in contact, the end of the cleaning blocks 22 will clean the side wall of the plywood, scraping off excess debris and overflowing glue; by adding the fixed frame 2, the movement path of the plywood can be corrected when it is placed, and at the same time, the side wall of the plywood will be cleaned by the cleaning blocks 22 when the plywood is moving, thereby reducing impurities on the side wall of the plywood.

[0027] like Figures 1 to 4 As shown, a pair of connecting plates 3 are fixedly connected to the end of the discharge port 14; a buffer plate 31 is fixedly connected to the end of the connecting plate 3; during operation, when the plywood is cut by the saw blade assembly 11, it will be sent out of the multi-blade saw body 1 by the transmission wheel 12, and then reach the surface of the buffer plate 31 through the discharge port 14, and then gradually slide down along the surface of the buffer plate 31; by adding the buffer plate 31, the plywood can be received when it is taken out after being cut, and the cut plywood is gradually moved down by the slope of the buffer plate 31, thereby slowing down the falling of the plywood and increasing the time for collecting the plywood.

[0028] like Figures 2 to 5 As shown, a fixing block 4 is fixedly connected to the top of the screw 16; the fixing block 4 and the screw 16 are correspondingly arranged; during operation, when the screw 16 is rotated, the fixing block 4 is gripped, and when force is applied to the fixing block 4 after gripping, the fixing block 4 will be subjected to force from multiple points. When subjected to force from multiple points, the rotational resistance of the fixing block 4 can be reduced, thereby accelerating the rotation of the screw 16; by adding the fixing block 4, the rotational speed of the screw 16 can be accelerated when force is applied, making the adjustment of the adjusting block 17 of the screw 16 faster.

[0029] like Figures 1 to 2 As shown, a baffle 5 is fixedly attached to the surface of the feed plate 15; multiple baffles 5 are provided on the feed plate 15; during operation, when the plywood enters the multi-blade saw body 1 and is cut, some wood chips will splash out from the feed port 13. At this time, the baffle 5 will intercept the splashed chips, thereby reducing the contact between wood chips and screw 16; by adding baffles 5, the screw 16 can be protected during use, reducing the impact caused by the contact between wood chips and screw 16.

[0030] like Figure 4As shown, friction pads 6 are fixedly attached to the surface of the buffer plate 31; multiple friction pads 6 are provided on the buffer plate 31; during operation, when the plywood slides on the buffer plate 31, it will come into contact with multiple friction pads 6 in sequence. When in contact, the friction pads 6 increase the friction between the plywood and the buffer plate 31, and the friction will reduce the moving speed of the plywood; by increasing the friction pads 6, the sliding speed of the plywood can be reduced when it slides, thereby reducing the force of the plywood falling off the bottom of the buffer plate 31.

[0031] Working principle: First, place the plywood onto the surface of the feed plate 15. Then, adjust the height between the pressure roller 19 and the surface of the feed plate 15 according to the thickness of the plywood, ensuring the height between them is slightly less than the thickness of the plywood. During adjustment, first rotate the screw 16. This rotation will move the adjusting block 17 via the thread, thereby moving the pressure roller 19 on the adjusting block 17. After adjustment, turn on the motor 18 to rotate the pressure roller 19, bringing the plywood closer to the pressure roller 19. Once close, the plywood and the pressure roller 19 will contact each other. When the plywood is touched, it is driven to move into the multi-blade saw body 1 when the pressure roller 19 rotates. At the same time, the plywood is squeezed by the pressure roller 19 when it enters. Because the gap between the pressure roller 19 and the feed plate 15 is smaller than the thickness of the plywood, the plywood is squeezed when it is moved. This eliminates the resistance generated when the plywood comes into contact with the saw blade assembly 11 by the forward transmission and squeezing force of the pressure roller 19, thereby increasing the protection during feeding. When the plywood is placed, it is first moved onto the roller 21, and then gradually moved towards the center of the fixed frame 2. During the movement, the ends of the plywood will... First, the plywood contacts the roller 23, which rolls to reduce friction between the plywood and the cleaning block 22. Then, both sides contact the ends of the cleaning block 22, which clean the sidewalls of the plywood, scraping away excess debris and spilled adhesive. After being cut by the saw blade assembly 11, the plywood is fed out of the multi-blade saw body 1 by the transmission wheel 12. It then reaches the surface of the buffer plate 31 through the discharge port 14 and gradually slides down the surface of the buffer plate 31. When the screw 16 rotates, it grips the fixing block 4. When force is applied to the fixing block 4, the fixing block 4 will be subjected to force from multiple points. When the fixing block 4 is subjected to force from multiple points, the rotational resistance of the fixing block 4 can be reduced, thereby accelerating the rotation of the screw 16. When the plywood enters the multi-blade saw body 1 and is cut, some wood chips will splash out from the feed port 13. At this time, the baffle 5 will intercept the splashed chips, thereby reducing the contact between the wood chips and the screw 16. When the plywood slides on the buffer plate 31, it will come into contact with multiple friction pads 6 in sequence. When in contact, the friction pads 6 will increase the friction between the plywood and the buffer plate 31. At this time, the friction will reduce the moving speed of the plywood.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
