Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of woodworking machinery, and in particular relates to a wood material bin which is preferably sawn and fed and can be stacked. Background Art
[0002] The current feeding method of the optimal saw mainly relies on conveyor belt transmission. The wood is placed on the belt, and the servo motor in the saw drives the conveyor belt to feed the wood into the optimal saw for sawing. When the optimal saw is used alone, the manual feeding method can still cope with it, but once it is connected in series with other woodworking machinery and equipment to form a production line, it will face many problems, such as material jamming, poor wood transportation, and reduced overall production efficiency.
[0003] The problem is particularly prominent after the rubber wood is polished and graded. When the visual equipment identifies short-section rubber wood (length 200mm-330mm) that needs to be cut, due to the high speed of the production line, the optimal saw needs to pause the conveyor belt during the cutting process, while the conveyor belt for feeding materials at the rear will not stop synchronously, causing the wood to pile up and collide with each other, thus causing a series of problems.
[0004] The current production process of planed rubber wood is as follows: the planed rubber wood is first inspected by visual equipment through a conveyor belt to determine the grade and whether it needs to be cut; then it enters the sorting area, and the sorting mechanism removes the wood that does not need to be cut off from the conveyor belt, while the wood that needs to be cut enters the preferred saw for sawing.
[0005] However, due to the unpredictability of the wood state and the fact that the continuous processing capacity of the optimal saw (30 meters / minute) is much lower than the speed of the front conveyor belt (42 meters / minute), when the wood that needs to be continuously cut exceeds the processing capacity of the optimal saw, problems such as material jamming, material collision, and material accumulation will occur, and even data errors may occur.
[0006] To deal with these problems, the current practice is to count the wood waiting to be cut. Once the number exceeds the set value, the front-end detection and sorting conveyor belt will slow down and wait for the optimal saw to complete the cut before speeding up. However, this method seriously affects the speed and efficiency of the entire production line and reduces production. Utility Model Content
[0007] In view of the deficiencies in the prior art, the utility model aims to provide a preferred saw feeding and stacking wood material bin, which solves the problem of how to store more wood at the front end of the preferred saw and how to ensure that the wood behind can stably enter the preferred saw when the conveyor belt stops at the moment of the preferred saw cutting off (150 milliseconds-400 milliseconds).
[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a preferred saw feeding and stacking wood material silo, including a conveying frame, a left limit baffle and a right limit baffle are respectively fixedly installed on both sides of the top of the conveying frame, a blowing mechanism fixing plate is fixedly installed on the top of the left limit baffle and the right limit baffle, a blowing air nozzle is arranged on the blowing mechanism fixing plate, a buffer strip is arranged at the front end of the left limit baffle and the right limit baffle, a limit block is arranged at the front end of the buffer strip, a groove is arranged at the top of the conveying frame and between the left limit baffle and the right limit baffle, a conveying chain is arranged inside the groove, and chain baffles are arranged at intervals on the outer surface of the conveying chain.
[0009] Preferably, the buffer bar is composed of an independent iron sheet, the upper part of the buffer bar is fixed and the lower part is suspended.
[0010] Preferably, the conveying chain is connected to the servo inside the saw, the chain baffles are evenly spaced on the surface of the conveying chain, the chain baffles are iron sheet structures turned outward on both sides, and the turned-out parts of the chain baffles are exposed at the top edge of the groove where the conveying chain is located.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The utility model realizes the stable and orderly entry and sawing of wood by designing a unique silo system at the front end of the optimal saw. The incoming wood will first be stacked in the silo, and the optimal saw will work according to its own sawing rhythm. The subsequent incoming wood has nothing to do with the start and stop of the optimal saw, and only needs to be stacked in the silo and wait. Through this system, the entry and sawing process of wood can be optimized, and the production efficiency and sawing quality can be improved.
[0013] 2. The upper part of the silo of the utility model is equipped with three air blowing nozzles. When the wood flies into the silo, the air blowing nozzles will blow air to press the wood steadily onto the table or other wood to ensure the stable entry of the wood.
[0014] 3. The front end of the silo of the utility model is designed with a buffer bar, which is composed of an independent iron sheet. When the wood flies into the silo and hits the buffer bar, the inertia force of the wood is effectively resolved because the upper part of the buffer bar is fixed and the lower part is suspended, so that the wood falls naturally and parallelly. At the same time, the design of the buffer bar takes into account the uneven ends of the wood. The buffer bar can be impacted at different times according to the inclination of the end to ensure that the wood is evenly stressed and prevent rollover. At the same time, the buffer bar is also equipped with a front limit device, that is, a limit block, to prevent the wood from being hit in the opposite direction after being impacted and causing rollover.
[0015] 4. On the platform for the wood landing of the utility model, a left limit baffle and a right limit baffle are arranged on both sides to ensure that the wood is kept in the correct conveying position.
[0016] 5. A groove is provided on the conveying platform of the utility model, and the conveying chain in the groove is connected to the servo in the saw. Every 350mm chain position, there is an outward-turned iron sheet exposed above the table surface, which is convenient for driving the wood to enter the optimal saw stably.

[0025] Refer to the following Figure 1-Figure 4 To describe a preferred saw feed stackable wood silo provided by one embodiment of the present application.
[0026] A preferred sawing feeding and stacking wood silo includes a conveying frame 1, a left limit baffle 2 and a right limit baffle 3 are fixedly installed on both sides of the top of the conveying frame 1, a blowing mechanism fixing plate 4 is fixedly installed on the top of the left limit baffle 2 and the right limit baffle 3, and a blowing air nozzle 5 is arranged on the blowing mechanism fixing plate 4. When the wood flies into the silo, the blowing air nozzle 5 will blow air to press the wood steadily on the table or other wood to ensure the stable entry of the wood. The front ends of the left limit baffle 2 and the right limit baffle 3 are provided with a buffer strip 6, and the front end of the buffer strip 6 is provided with a limit stopper 7. The design of the buffer strip 6 takes into account the uneven ends of the wood, and the buffer strip 6 can be impacted in time according to the inclination of the end to ensure that the wood is evenly stressed and prevented from rolling over. At the same time, the buffer strip is also equipped with a front limit device, that is, a limit stopper 7, to prevent the wood from being hit in the opposite direction after being impacted and causing rollover. Limit stops are arranged on both sides of the platform where the wood lands to ensure that the wood remains in the correct conveying position. A groove is provided at the top of the conveying frame 1 and between the left limit baffle 2 and the right limit baffle 3 , a conveying chain 8 is provided inside the groove, and chain baffles 9 are provided at intervals on the outer surface of the conveying chain 8 .
[0027] Furthermore, the buffer bar 6 is composed of an independent iron sheet, the upper part of the buffer bar 6 is fixed and the lower part is suspended. When the wood flies into the silo and hits the buffer bar 6, since the upper part of the buffer bar 6 is fixed and the lower part is suspended, the inertia force of the wood is effectively resolved, causing the wood to fall naturally and parallel.
[0028] In a further embodiment, the conveyor chain 8 is connected to the servo inside the saw, and the chain baffles 9 are evenly distributed on the surface of the conveyor chain 8. The chain baffles 9 are iron sheet structures that are turned outward on both sides. The turned-out parts of the chain baffles 9 are exposed at the top edge of the groove where the conveyor chain 8 is located. Every chain position of approximately 350 mm, there is an turned-out iron sheet exposed above the table top. These iron sheets are used to drive the wood into the preferred saw. This design allows the wood to enter the preferred saw at intervals to prevent collision and merging together to cause data errors and other problems.
[0029] In combination with the above embodiments, the specific working process of a preferred saw feeding and stacking wood silo of the present application is described: the utility model realizes the stable and orderly entry and sawing of wood by designing a unique silo system at the front end of the preferred saw. The incoming wood will first be stacked in the silo, and the preferred saw will work according to its own sawing rhythm. The subsequent incoming wood has nothing to do with the start and stop of the preferred saw, and only needs to be stacked in the silo and wait.
[0030] The silo uses three mechanisms to ensure a steady flow of wood:
[0031] 1. Three air blowing nozzles 5 are provided on the upper part of the silo. When the wood flies into the silo, the air blowing nozzles 5 will blow air to press the wood steadily onto the table or other wood.
[0032] 2. A buffer bar 6 is designed at the front end of the silo, which is composed of an independent iron sheet. When the wood flies into the silo and hits the buffer bar 6, the inertia force of the wood is effectively resolved because the upper part of the buffer bar 6 is fixed and the lower part is suspended, so that the wood falls naturally and parallel.
[0033] 3. The design of the buffer strip 6 takes into account the uneven ends of the wood. The buffer strip 6 can be impacted at different times according to the inclination of the ends to ensure that the wood is evenly stressed and prevent it from rolling over. At the same time, the buffer strip is also equipped with a front limit device, namely, a limit stopper 7, to prevent the wood from rolling over due to the reverse impact after the impact.
[0034] 4. On the platform where the wood falls, a left limit baffle 2 and a right limit baffle 3 are set on both sides to ensure that the wood remains in the correct conveying position.
[0035] 5. A groove is provided on the conveying platform, and the conveying chain 8 in the groove is connected to the servo in the saw. Every 350mm chain position, there is an outward-turned iron sheet exposed above the table surface, which is used to drive the wood into the optimal saw.
[0036] 6. A height-adjustable block is installed at the front end of the silo, allowing only one piece of wood to pass through. When this piece of wood enters the optimal saw, the wood above will fall to the table, and then the iron sheet on the conveyor chain 8 will continue to push the wood into the optimal saw, forming a cycle operation.
[0037] Through this system, the wood entry and sawing process are optimized, improving production efficiency and sawing quality.
[0038] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
