Description

Technical Field

[0001] This invention relates to the field of board conveying technology, specifically a wood board clamping and conveying device. Background Technology

[0002] In the field of board conveying technology, especially in equipment involving the clamping and conveying of wood boards, the tension adjustment of the conveyor chain is a crucial factor in ensuring stable equipment operation and conveying accuracy. Conventional conveyor chain tension adjustment methods often involve adding or removing chain units (i.e., disassembling and assembling chain links) to adjust the total length of the conveyor chain. This adjustment method is a type of "stop-and-go stepped adjustment," meaning the equipment must be stopped, and the chain must be disassembled to adjust the tension by increasing or decreasing the number of chain links.

[0003] However, the existing solutions described above have significant shortcomings in practical applications. First, their operation is extremely cumbersome and time-consuming, severely impacting production line efficiency. Especially when handling materials requiring continuous operation, prolonged downtime can lead to decreased production efficiency or material backlog. Second, simply adding or removing chain links cannot achieve smooth, precise adjustments to the conveyor chain tension; the adjustment range is abrupt and inconsistent, making it difficult to achieve optimal tension. Furthermore, frequent disassembly and reassembly of the chain can disrupt the precise fit between the chain link pins and sleeves, accelerating chain wear and shortening its lifespan.

[0004] Therefore, a wood board clamping and conveying device is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a wood board clamping and conveying device that can be precisely tensioned without adding a conveyor chain unit.

[0006] The objective of this invention is achieved through the following technical solution: a wood board clamping and conveying device, comprising a conveyor body, a suspended conveying system provided above the end of the conveyor body, the wood board being placed onto the conveyor body via the conveying system, a drive shaft and a driven shaft being rotatably connected inside the conveyor body, a drive sprocket and a driven sprocket being fixedly connected to the drive shaft and the driven shaft respectively, a conveying chain being meshed on the drive sprocket and the driven sprocket, and a bottom support plate being provided on the conveying chain;

[0007] Both ends of the driven shaft are fixedly connected to a tensioning slider. An inclined push rod is slidably connected inside the tensioning slider, and a cleaning component is provided at the bottom of the tensioning slider. The inclined push rod is fixedly connected inside a fixed block. A tensioning screw is threaded inside the fixed block, and a locking block is threaded onto the tensioning screw. The locking block is rotatably connected to a fixed plate, and a preload spring is hinged to the fixed plate.

[0008] Furthermore: the cleaning component includes a connecting block, which is fixedly connected to the bottom of the adjusting slider, and a rotating shaft is rotatably connected to both sides of the connecting block. A brush slider and a lubrication slider are slidably connected on the rotating shaft. A cleaning brush is fixedly connected to the end of the brush slider facing the conveyor chain, and a lubrication brush is fixedly connected to the end of the lubrication slider facing the conveyor chain.

[0009] Furthermore: the brush slider is positioned at the rear end of the lubrication slider along the direction of movement of the conveyor chain, and both the brush slider and the lubrication slider are fixedly connected to a clamping spring at the end away from the conveyor chain, with the other end of the clamping spring fixedly connected inside the connecting block.

[0010] Furthermore, the front and rear ends and the top and bottom ends of the fixed block are symmetrically fixedly connected with inclined push rods. The horizontal inclined intersection of the inclined push rods is located on the center line of symmetry of the fixed block, and the vertical inclined intersection of the inclined push rods is located on the axis of the driven shaft.

[0011] Furthermore: one end of the pre-tension spring is hinged to the fixed plate, and the other end is hinged to the adjusting slider, and the pre-tension spring is obliquely arranged in the horizontal plane; one end of the fixed plate is slidably connected to a limiting block, and the limiting block is rotatably connected to the adjusting screw.

[0012] Furthermore: the conveyor chain is provided with several sets of storage plates, and a base plate is slidably connected inside the storage plate. The base plate has a storage groove for placing bulk materials.

[0013] Furthermore, both ends of the driven shaft and the driving shaft are fixedly connected with limiting blocks to facilitate the adjustment of the centering position of the base plate.

[0014] Furthermore: the adjusting slider is slidably connected to the sliding groove, the sliding groove is opened in the conveyor body, and the cross-section of the sliding groove is T-shaped.

[0015] Furthermore: one end of the drive shaft passes through the conveyor body and is fixedly connected to a drive motor, which is fixedly connected to the conveyor body.

[0016] Furthermore, one end of the adjusting screw is fixedly connected to an easy-to-operate adjusting knob, and the other end is rotatably connected to the conveyor body, and the adjusting screw is located at the symmetrical center of the driven shaft.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] 1. By using symmetrically arranged oblique push rods on the fixed block, the resultant force of the transmission thrust is completely passed through the center line of the driven shaft, eliminating overturning torque and eccentric load during the transmission process, and avoiding drive shaft misalignment, unilateral wear and jamming; in conjunction with the adjusting screws arranged along the symmetrical center of the driven shaft, the movement of the adjusting sliders on the left and right sides is completely synchronized, fundamentally preventing uneven tension and lateral deviation of the conveyor chain; the oblique wedge force-enhancing transmission structure combined with trapezoidal self-locking threads can resist impact and prevent tension failure.

[0019] 2. By adjusting the screw and the fixed block through the threaded transmission, the tension stroke of the conveyor chain can be coarsely adjusted, which can accommodate the large elongation of the conveyor chain after long-term use; by cooperating with the locking block and the fixed plate, the pretension force of the pretension spring can be independently finely adjusted without adjustment interference; in conjunction with the pretension spring arranged parallel to the inclined top rod, the tension can be finely adjusted in daily operation, which can compensate for the slight deformation and tension fluctuation of the conveyor chain in real time.

[0020] 3. The cleaning components integrated at the bottom of the adjusting slider can complete the cleaning and lubrication operations. The arrangement of cleaning before lubrication can avoid dust mixing into the grease and causing abrasive wear. The clamping spring can ensure that the cleaning brush and lubrication brush are always in contact with the working surface, avoiding gaps after wear. It continuously removes mud, crop residues and dust from the conveyor chain and sliding mating surfaces, extending the service life of the core moving parts. Attached Figure Description

Detailed Implementation

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0033] like Figures 1 to 8 The diagram shown is a schematic representation of an embodiment of a wood board clamping and conveying device provided by the present invention.

[0034] A wood board clamping and conveying device includes a conveyor body 1. A suspended conveying system is provided above the end of the conveyor body 1. The wood boards are placed onto the conveyor body 1 through the conveying system. A drive shaft 2 and a driven shaft 3 are rotatably mounted inside the conveyor body 1. A drive sprocket 4 is fixedly mounted on the shaft of the drive shaft 2. A driven sprocket 5 corresponding to the position of the drive sprocket 4 is fixedly mounted on the shaft of the driven shaft 3. A closed-loop conveying chain 6 is meshed between the drive sprocket 4 and the driven sprocket 5. A bottom support plate 7 for carrying bulk materials is installed on the links of the conveying chain 6 for conveying bulk materials. A cutting mechanism is also fixedly mounted on the conveyor body 1.

[0035] Both ends of the driven shaft 3 are fixedly connected to a tensioning slider 8. The tensioning slider 8 has an inclined sliding hole that matches the inclined push rod 9. The inclined push rod 9 is slidably assembled in the inclined sliding hole. The sliding fit between the inclined push rod 9 and the inclined sliding hole forms a wedge force-increasing transmission structure, which can convert the rotational motion of the tensioning screw 12 into a linear translation of the tensioning slider 8 along the tension direction of the conveyor chain 6, thereby realizing the tension adjustment of the conveyor chain 6. A cleaning component 10 is integrated at the bottom of the tensioning slider 8. The tail ends of all the inclined push rods 9 are rigidly fixed in the same fixing block 11. The fixing block 11 has a threaded hole, and the tensioning screw 12 is threadedly connected in the threaded hole. The shaft of the tensioning screw 12 is also threadedly connected to a locking block 13. The locking block 13 is rotatably mounted on the side of the fixing plate 14 through a bearing structure. A preload spring 15 is hinged on the plate body of the fixing plate 14.

[0036] The core support component of the cleaning assembly 10 is the connecting block 16, which is rigidly fixed to the bottom of the tightening slider 8. Rotating shafts 17 are rotatably installed on both sides of the connecting block 16. Brush sliders 18 and lubrication sliders 19 are slidably mounted on the shafts of the rotating shafts 17. A cleaning brush 20 is fixedly connected to the end of the brush slider 18 facing the conveyor chain 6, and a lubrication brush 21 is fixedly connected to the end of the lubrication slider 19 facing the conveyor chain 6. The brush slider 18 is arranged at the rear end of the lubrication slider 19 along the running direction of the conveyor chain 6. It can first scrape away mud, crop residues and dust from the conveyor chain 6 and the sliding mating surface, and then the lubrication brush 21 applies grease to the mating surface, so as to realize the simultaneous completion of the tightening action and cleaning and lubrication. A clamping spring 22 is fixedly connected to the end of the brush slider 18 and the lubrication slider 19 away from the conveyor chain 6. The other end of the clamping spring 22 is fixedly installed in the internal cavity of the connecting block 16, which can ensure that the cleaning brush 20 and the lubrication brush 21 are always in contact with the working surface and avoid the appearance of gaps after wear.

[0037] The front and rear ends and the top and bottom ends of the fixed block 11 are symmetrically fixed with inclined push rods 9. The intersection of the extended axes of multiple sets of inclined push rods 9 in the horizontal plane falls on the symmetrical center line of the fixed block 11. The intersection of the extended axes of multiple sets of inclined push rods 9 in the vertical plane is in the same horizontal plane as the axis of the driven shaft 3. This symmetrical arrangement allows the resultant force of the transmission thrust of each set of push rods to pass completely through the axis of the driven shaft 3, eliminating the overturning moment and eccentric load during the transmission process, avoiding the driven shaft 3 from tilting, unilateral wear, and jamming. At the same time, it ensures that the movement of the left and right tensioning sliders 8 is completely synchronized, avoiding uneven tension and lateral deviation of the conveyor chain 6.

[0038] One end of the preload spring 15 is hinged to the plate of the fixed plate 14, and the other end is hinged to the side of the tensioning slider 8. The preload spring 15 is arranged obliquely in the horizontal plane, and the axis of the preload spring 15 is parallel to the axis of the oblique push rod 9 on the same side. This oblique arrangement makes the direction of the preload force coincide with the main path of the transmission of the tension force of the conveyor chain 6, with no radial force loss. It can compensate for the slight wear and elongation of the conveyor chain 6, thermal expansion and contraction deformation, and tension fluctuations caused by intermittent start and stop, so as to realize fine-tuning of tension in daily operation. At the same time, it eliminates the lateral pressure of the tensioning slider 8, reduces sliding friction resistance, and avoids the need for adjustment. The slider 8 is stuck; the end of the fixed plate 14 away from the fixed block 11 is rotatably connected to a locking block 13 that is threadedly engaged with the adjusting screw 12. A smooth sliding hole is opened in the middle of the fixed plate 14, and it is sleeved on the outside of the adjusting screw 12 through the smooth sliding hole, without thread engagement with the adjusting screw 12. An insert block 30 is integrally provided on the side of the fixed plate 14 facing the fixed block 11. The insert block 30 is slidably engaged in the insert groove 31, which is opened in the limiting block 29. The limiting block 29 is rotatably connected to the adjusting screw 12. The fixed plate 14 can slide in the insert block 30 and the limiting block 29. Through the cooperation of the locking block 13, the limiting block 29, the insert block 30 and the insert groove 31, the tension stroke of the conveyor chain 6 and the pretension force of the pretension spring 15 can be independently adjusted, avoiding interference between the two adjustments. At the same time, it provides a stable installation reference for the pretension spring 15, ensuring that the fixed plate 14 does not deviate during translation.

[0039] Several sets of placement plates 23 are fixedly installed on the links of the conveyor chain 6. A sliding limiting groove is provided on the inner side of each placement plate 23, and a base plate 7 is slidably mounted within the sliding limiting groove. A placement groove 24 for placing loose materials is provided on the upper surface of the base plate 7. The placement plate 23 provides a sliding installation and limiting reference for the base plate 7, ensuring that the base plate 7 moves synchronously with the conveyor chain 6 without shifting. The sliding assembly structure can be adapted to different specifications of agricultural product packaging by replacing the base plate 7 of the corresponding size, without adjusting the conveyor chain 6 and the main body of the equipment, thus improving the efficiency of packaging specification changes. The placement groove 24 can provide positioning for loose materials, preventing deviation during conveying and ensuring the accuracy of subsequent forming and sealing processes. To ensure that the placement plate 23 does not interfere with the operation of the cleaning component 10 during conveying, a suitable chamfer can be machined at the edge of the placement plate 23, or a guide ramp 32 can be integrally formed at the front end of the placement plate 23. The guide ramp 32 contacts the brush slider 18 and the lubrication slider 19 before the shelf 23. The guide ramps on both sides drive the brush slider 18 and the lubrication slider 19 to generate relative displacement along the axial direction of the rotation shaft 17, so that a gap is formed between the two sliders that the shelf 23 can pass through, thereby eliminating the motion interference between the shelf 23 and the cleaning component 10.

[0040] Both ends of the drive shaft 2 and driven shaft 3 are fixedly equipped with limit blocks 25. The limiting surfaces of the limit blocks 25 correspond to the sides of the bottom support plate 7. When the bottom support plate 7 runs to the reversing position of the drive shaft 2 and driven shaft 3, it can assist in correcting the lateral position of the bottom support plate 7, avoid the accumulation of slight deviations during the conveying process, and improve the centering accuracy of the bottom support plate 7. One end of the drive shaft 2 passes through the side wall of the conveyor body 1 and is rigidly fixedly connected to the output shaft of the drive motor 27. The body of the drive motor 27 is fixed on the external extension area of ​​the conveyor body 1, providing controllable power input to the conveyor chain 6, realizing the intermittent and precise movement of the conveyor chain 6, matching the working rhythm of the forming, filling, sealing and cutting processes of the packaging machine. The rigid fixation with the conveyor body 1 can reduce running vibration and ensure the accuracy and stability of the conveying step distance.

[0041] The tensioning slider 8 is slidably assembled in the sliding groove 26. The sliding groove 26 is opened on the inner side of the conveyor body 1 along the tensioning direction of the conveyor chain 6. The connecting block 16 in the cleaning component 10 is slidably assembled in the connecting groove opened in the conveyor body 1. The connecting groove is located below the sliding groove 26. The T-shaped sliding groove 26 provides linear guide limit for the tensioning slider 8, strictly limiting the tensioning slider 8 to only be able to move linearly along the tensioning direction of the conveyor chain 6, ensuring the linear accuracy of the tension adjustment of the conveyor chain 6, and avoiding the tensioning slider 8 from deflection or jamming.

[0042] One end of the adjusting screw 12 is fixedly connected to an adjusting knob 28 for easy manual operation. The other end of the adjusting screw 12 is rotatably installed inside the conveyor body 1 via a bearing seat. The entire adjusting screw 12 is arranged along the front and rear symmetrical center planes of the driven shaft 3 and is in the same plane as the symmetrical center line of the driven shaft 3. The adjusting screw 12 adopts a trapezoidal self-locking thread. The adjusting knob 28 provides a manual adjustment interface for the operator, and the tension of the conveyor chain 6 can be adjusted without special tools. The centrally arranged structure ensures the synchronous adjustment of the adjusting sliders 8 on the left and right sides, eliminating the need for additional synchronous connecting rods and making the structure simpler.

[0043] Working principle: After the device is assembled, rotating the tensioning knob 28 causes the tensioning screw 12 to rotate in place. Through threaded transmission, the fixed block 11 is moved axially along the tensioning screw 12, which in turn causes the symmetrically arranged inclined push rods 9 on the fixed block 11 to move synchronously. The inclined push rods 9 and the inclined sliding holes in the tensioning slider 8 form a wedge-shaped force-increasing transmission, converting the rotational motion of the tensioning screw 12 into a linear translation of the tensioning slider 8 along the tensioning direction of the conveyor chain 6. This causes the driven shaft 3 to move away from the drive shaft 2, adjusting the closed-loop conveyor chain 6 to the designed tension. After tightening, the tensioning screw 12 is locked in place by its trapezoidal self-locking thread.

[0044] The locking block 13 on the rotating tensioning screw 12 moves axially along the tensioning screw 12 via threaded transmission, pushing the insertion block 30 on the fixing plate 14 to slide within the insertion slot 31. This, in turn, moves the fixing plate 14 axially along the tensioning screw 12, adjusting the compression of the oblique preload spring 15 and achieving precise setting of the preload force of the preload spring 15. Since the fixing plate 14 and the tensioning screw 12 are not threadedly engaged, the adjustment of the preload spring 15 does not change the pre-set basic tension stroke of the conveyor chain 6, achieving independent and interference-free adjustment of the tension stroke and preload force.

[0045] The drive motor 27 drives the drive shaft 2 and drive sprocket 4 to rotate synchronously, and drives the conveyor chain 6, driven sprocket 5, and driven shaft 3 to move intermittently and precisely through meshing transmission; the placement plate 23 on the conveyor chain 6 drives the bottom support plate 7 to move synchronously, and the bulk materials and materials to be packaged laid flat in the placement groove 24 of the bottom support plate 7 complete the packaging process such as forming, filling, sealing, and cutting along with the conveyor chain 6; the limiting blocks 25 at both ends of the drive shaft 2 and driven shaft 3 assist in correcting the lateral position of the bottom support plate 7 when it passes through the reversing station to avoid the accumulation of conveying deviation.

[0046] As the adjusting slider 8 moves along the sliding groove 26, the cleaning component 10 integrated at its bottom moves synchronously. The clamping spring 22 in the cleaning component 10 continuously pushes the cleaning brush 20 and the lubricating brush 21 to adhere to the working surface. First, the cleaning brush 20 scrapes away crop residues and dust from the conveyor chain 6 and the sliding mating surface, and then the lubricating brush 21 applies grease to the mating surface to complete the cleaning and lubrication operation of the conveyor chain 6.

[0047] During daily operation, when the conveyor chain 6 experiences slight wear and elongation, thermal expansion and contraction deformation, or tension fluctuations due to intermittent start-stop, the obliquely arranged pre-tensioning spring 15 directly pushes the tensioning slider 8 to move in real time through the pre-tensioning force that coincides with the main path of the tensioning force. This automatically compensates for the length increment and tension fluctuations of the conveyor chain 6, keeping the conveyor chain 6 in a stable constant tension state throughout the entire process.

[0048] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
