[0028] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0029] Reference Figure 1-7 This utility model provides an improved sawing equipment for particleboard production, which includes: a workbench 1, on which a dust protection component 2, a feeding component 3 and a pressing positioning component 4 are provided;

[0030] The dust protection component 2 includes a protective cover 21 and a sealing plate 23. The protective cover 21 is fixedly installed on the upper surface of the workbench 1. A slot 22 is opened on one side of the protective cover 21, and a sliding groove is opened on the inner wall of the slot 22. A first spring 24 is fixedly installed on the upper surface of the sealing plate 23, and the top of the first spring 24 is fixedly installed on the inner top of the sliding groove. The sealing plate 23 is slidably connected to the inner wall of the sliding groove. A pin 25 is fixedly installed on the lower surface of the sealing plate 23. An insertion hole is opened on the upper surface of the workbench 1, and observation windows are provided on both sides of the protective cover 21.

[0031] In the improved sawing equipment for particleboard production of this utility model, when the feeding component 3 pushes the particleboard to move towards the slot 22, the front end of the particleboard contacts the inclined surface at the bottom of the sealing plate 23 and applies pressure. At this time, the sliding groove of the sealing plate 23 is set at the bottom, and the first spring 24 is in normal state and fixed to the top of the inner wall of the slot 22. Under the pressure of the board, the sealing plate 23 overcomes the pressure of the first spring 24 and slides upward along the inner wall of the sliding groove. The pin 25 moves upward and disengages from the insertion hole on the upper surface of the worktable 1. The slot 22 is opened and the board passes through smoothly. When the board has completely passed through the slot 22, it loses the pressure of the particleboard, and the first spring 24 begins to release the compression force. Under the action of the compression force, the sealing plate 23 slides downward along the sliding groove to reset, and the pin 25 is re-inserted into the insertion hole accurately. The slot 22 is closed, thereby restoring the protective cover 21 to a closed state and effectively preventing the dust generated by sawing from overflowing. The operator can monitor the sawing status of the board inside the protective cover 21 at any time through the observation window.

[0032] The feeding assembly 3 includes a forward and reverse motor 31 and a housing 32, both of which are fixedly installed on the lower surface of the worktable 1. A threaded long rod 33 is rotatably installed on the inner wall of the housing 32. One end of the threaded long rod 33 is fixedly installed on the output shaft of the forward and reverse motor 31. An internal threaded ring 34 is threadedly installed on the outer wall of the threaded long rod 33. A long connecting rod 35 is fixedly installed on the outer wall of the internal threaded ring 34. A push plate 36 is fixedly installed at the top of the long connecting rod 35. Both the outer wall of the housing 32 and the upper surface of the worktable 1 are provided with stroke grooves. The long connecting rod 35 is slidably connected to the inner wall of the stroke groove.

[0033] In the improved sawing equipment for particleboard production of this utility model, when the forward and reverse motor 31 is started, the motor output shaft drives the threaded rod 33 to rotate inside the housing 32. Since the threaded rod 33 and the inner threaded ring 34 are threadedly engaged, when the threaded rod 33 rotates, the inner threaded ring 34 will move along the axial direction of the threaded rod 33. The movement of the inner threaded ring 34 is transmitted through the long connecting rod 35. The long connecting rod 35 passes through the stroke groove between the outer wall of the housing 32 and the upper surface of the worktable 1, and can only slide in a straight line under the restriction of the stroke groove. The push plate 36 fixed at the top of the long connecting rod 35 will move with the straight line movement of the long connecting rod 35, thereby pushing the board placed on the worktable 1 forward to realize the feeding function. When the forward and reverse motor 31 reverses, the inner threaded ring 34 moves in the opposite direction, and the push plate 36 returns to its original position, waiting for the next feeding. By controlling the forward and reverse rotation and rotation time of the forward and reverse motor 31, the feeding distance and feeding rhythm of the particleboard can be precisely controlled.

[0034] The downward positioning assembly 4 includes a mounting side plate 41, a second upper plate 44, and a knob 46. The bottom of the mounting side plate 41 is fixedly mounted on the upper surface of the workbench 1. A first upper plate 42 is fixedly mounted on the outer wall of the mounting side plate 41. A spring groove 47 is formed inside the first upper plate 42. A second spring 48 is fixedly mounted on the top of the inner spring groove 47. A spring pressure plate 49 is fixedly mounted on the bottom end of the second spring 48. A connecting rod 410 is fixedly mounted on the lower surface of the spring pressure plate 49. A first downward pressure plate 43 is fixedly mounted on the bottom end of the connecting rod 410. One side of the second upper plate 44 is fixedly mounted on the outer wall of the push plate 36. A gear groove 411 is formed inside the second upper plate 44. The top of the inner gear groove 411 is rotated by a rotating shaft. The device is equipped with a second bevel gear 415. A threaded rod 413 is fixedly installed on the outer wall of the second bevel gear 415. A threaded cylinder 412 is threadedly installed on the outer wall of the threaded rod 413. Limiting blocks are fixedly installed on both sides of the threaded cylinder 412. A limiting groove is opened at the bottom of the gear groove 411. The limiting blocks and the inner wall of the limiting groove are slidably connected. A second lower pressure plate 45 is fixedly installed at one end of the threaded cylinder 412. A knob 46 is rotatably installed on the outer wall of the push plate 36. A drive shaft is fixedly installed on the outer wall of the knob 46. The drive shaft passes through the through hole opened on the outer wall of the push plate 36 and the outer wall of the second upper plate 44. A first bevel gear 414 is fixedly installed at the other end of the drive shaft. The first bevel gear 414 and the second bevel gear 415 are meshed together.

[0035] In the improved sawing equipment for particleboard production described in this utility model, one side of the board is tightly attached to the push plate 36 to complete the initial placement of the board. Subsequently, the operator rotates the knob 46, which drives the first bevel gear 414 to rotate synchronously via the drive shaft. Since the first bevel gear 414 and the second bevel gear 415 mesh with each other, the rotational motion of the first bevel gear 414 is transmitted to the second bevel gear 415, driving the second bevel gear 415 to rotate within the gear groove 411. The threaded rod 413, fixedly connected to the second bevel gear 415, rotates with the rotation of the second bevel gear 415. The threaded rod 413 is connected to the threaded cylinder 412 through a threaded structure. The rotation of the threaded rod 413 is converted into the linear motion of the threaded cylinder 412. The limiting blocks on both sides of the threaded cylinder 412 slide in the limiting groove, restricting its direction of movement and ensuring that the threaded cylinder 412 can only move vertically downward. When the threaded cylinder 412 moves downward, it drives the second lower pressure plate 45 fixed at one end to move downward synchronously. The second lower pressure plate 45 applies pressure to the end of the plate near the push plate 36, completing the first step of positioning the plate. When the plate enters the protective cover 21... Inside, the other end of the sheet material contacts and is squeezed by the first lower pressure plate 43. The first lower pressure plate 43 moves upward under the force of the sheet material. The first lower pressure plate 43 drives the spring pressure plate 49 to move upward through the connecting rod 410. The spring pressure plate 49 squeezes the second spring 48, so that the second spring 48 is in a compressed state. The second spring 48 generates elastic force during the compression process. This elastic force is transmitted to the first lower pressure plate 43 through the spring pressure plate 49 and the connecting rod 410, so that the first lower pressure plate 43 continuously applies pressure to the other end of the sheet material. Thus, the second lower pressure plate 45 and the first lower pressure plate 43 work together to apply force from both ends of the sheet material, and fix the sheet material firmly on the worktable 1. Then the sawing machine (not shown in the figure) can be started to cut the sheet material.

[0036] Working principle: First, one side of the board is placed against the push plate 36. Then, the knob 46 is rotated. The knob 46 drives the first bevel gear 414 to rotate via the drive rod. The first bevel gear 414 meshes with the second bevel gear 415, causing the first bevel gear 414 to rotate. The rotation of the second bevel gear 415 simultaneously drives the threaded rod 413 to rotate. The threaded rod 413 is threadedly connected to the inner wall of the threaded cylinder 412. As the threaded rod 413 rotates, it causes the threaded cylinder 412 to move downward. The threaded cylinder 412 then simultaneously drives the second lower pressure plate 45 to move downward, causing the second lower pressure plate 45 to press down and position one end of the board, completing the first step of positioning the wood. Then, the forward and reverse motor 31 is started. The output shaft of the forward and reverse motor 31 drives the threaded long rod 33 to rotate. An internal threaded ring 34 is threaded on the outer wall of the threaded long rod 33. As the threaded long rod 33 rotates, it causes the internal threaded ring 34 to move on its outer wall. The internal threaded ring 34 then drives the push plate via the long connecting rod 35. The push plate 36 moves the plate, causing it to move forward. The plate presses against the sealing plate 23, causing the bottom of the sealing plate 23 to move upward. Simultaneously, the sealing plate 23 presses against the first spring 24, compressing it. The pin 25 on the lower surface of the sealing plate 23 moves out of the hole on the worktable 1. After the sealing plate 23 is opened, the plate is pushed into the interior of the protective cover 21. The other end of the plate presses against the first lower pressure plate 43, forcing it to move upward. As the first lower pressure plate 43 moves upward, it drives the spring pressure plate 49 through the connecting rod 410 to press against the second spring 48, compressing it. The elastic force generated by the second spring 48 is transmitted to the first lower pressure plate 43, causing it to press against the other end of the plate. After positioning the plate, the saw (not shown in the figure) on the protective cover 21 is started to cut the plate.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
