Description

Technical Field

[0001] This utility model relates to the technical field of log cutting equipment, and in particular to a horizontal log cutting machine with multiple pieces. Background Technology

[0002] Currently used log sawing machines typically include a worktable with a cutting saw blade, allowing only one log to be cut at a time. This method of cutting not only involves numerous steps and low efficiency, but also poses safety risks. Furthermore, the sawdust is scattered everywhere, creating a poor working environment and increasing the likelihood of workplace injuries. Additionally, it demands a high level of technical skill from the operators, making it unsuitable for future development needs.

[0003] Utility model patent CN201423689Y discloses a multi-piece log saw, including a frame. The frame is equipped with a conveyor belt, and two passive pressure rollers are positioned directly above the conveyor belt to hold the logs in place. The conveyor belt is flanked by upper and lower multi-piece saw blades, which are coaxially mounted and used to synchronously cut the corresponding sides of the logs. The axial distance L between the upper and lower multi-piece saw blades in the front-to-back direction is three to six centimeters. Upper and lower guide rollers are coaxially mounted on the discharge side of the multi-piece saw blades and used to guide the log pieces cut by the saw blades. Although the device is easy to operate, it still has the following defects: the distance between each saw blade and guide wheel in the upper and lower multi-blade saw assembly and the upper and lower multi-blade guide wheel is adjusted by the washers. However, during adjustment, the saw blades or guide wheels need to be disassembled and replaced with washers of different sizes in turn. The operation process is complicated and inefficient. Moreover, it is easy to cause injury when disassembling and assembling the saw blades. It is urgent to improve it. Utility Model Content

[0004] The purpose of this utility model is to provide a horizontal log saw with multiple blades, which has the advantages of automatic adjustment of the blade spacing without disassembling the blades during adjustment, resulting in high efficiency and good safety.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A horizontal log saw includes a machine body with a log conveying mechanism on the machine body. Two pressure roller assemblies are located above the log conveying mechanism, and a sawing assembly is located between the two pressure roller assemblies. The sawing assembly includes an upper sawing roller assembly and a lower sawing roller assembly. The upper and lower sawing roller assemblies have the same structure, each including a sawing shaft and multiple sawing blades evenly spaced on the sawing shaft. The sawing blades are sleeved on the sawing shaft, and the sawing shaft is provided with a sawing blade spacing adjustment mechanism for automatically adjusting the spacing between the sawing blades.

[0007] By adopting the above technical solution, the logs to be processed are transported to the processing position by the log conveying mechanism. The logs pass through two pressure roller assemblies and the cutting assembly between the two pressure roller assemblies in sequence. The two pressure roller assemblies use their own gravity to press the logs to be processed onto the log conveying mechanism, preventing the ends of the logs from lifting or rolling during the cutting process, thus effectively ensuring the cutting accuracy. The cutting blade spacing adjustment mechanism on the cutting blade shaft is used to automatically adjust the spacing between adjacent cutting blades on the cutting blade shaft and fix the cutting blades on the cutting blade shaft at a suitable spacing. The cutting blades do not need to be disassembled during the adjustment process, which is not only highly efficient but also safe.

[0008] A further feature of this invention is that both ends of the cutting blade shaft are rotatably connected to the machine body, one end of the cutting blade shaft is connected to the output shaft of the cutting drive motor fixed on the machine body, and the other end of the cutting blade shaft is provided with an adjustment hole coaxial with the cutting blade shaft. The cutting blade spacing adjustment mechanism includes an adjustment shaft disposed in the adjustment hole, and the adjustment shaft is coaxial with the adjustment hole and threadedly connected.

[0009] The outer wall of the adjusting shaft is provided with multiple circumferentially extending grooves. The number of grooves matches the number of cutting blades. The spacing between adjacent grooves is equal, and the spacing between adjacent grooves shows a trend of gradually increasing or gradually decreasing.

[0010] An adjustment groove is provided on the outer wall of the cutting blade shaft. The adjustment groove is parallel to the axis of the cutting blade shaft. The adjustment groove is connected to the adjustment hole. An adjustment block is provided on the inner wall of the cutting blade that can slide along the adjustment groove. The adjustment block passes through the adjustment groove and extends into the opposite sliding groove and slides into the sliding groove.

[0011] By adopting the above technical solution, the cutting drive motor is used to drive the cutting blade shaft to rotate at high speed, which in turn drives the cutting blade to rotate at high speed, thereby realizing the cutting operation. When it is necessary to adjust the spacing of the cutting blades, the adjusting shaft is manually controlled to rotate at a certain angle relative to the cutting blade shaft. When the adjusting shaft rotates, the adjusting block will slide relative to the slide groove on the adjusting shaft. Since the adjacent slide grooves gradually increase or decrease in size, when the adjusting block slides relative to the slide groove on the adjusting shaft, the spacing between the adjusting blocks gradually increases or decreases, thereby gradually increasing or decreasing the spacing between the cutting blades fixedly connected to each adjusting block until it matches the preset spacing. Therefore, the spacing adjustment operation between adjacent cutting blades is realized. The operation process is simple and convenient, and the blades do not need to be disassembled during adjustment, making it safe and efficient.

[0012] After the spacing adjustment operation is completed, each cutting blade engages with the adjustment groove and slide groove respectively through the adjustment block. Therefore, during the cutting operation, there will be no relative movement between the cutting blade and the cutting blade shaft. This ensures that the cutting blade shaft and the cutting blade always rotate synchronously at high speed during the high-speed rotation of the cutting blade shaft, effectively avoiding the problem of the shaft rotating but the blade not rotating, which affects the stability of the cutting process.

[0013] In addition, since the cutting blade spacing adjustment mechanism is located inside the cutting blade shaft, it will not affect the cutting position of the cutting blade. The entire cutting blade can be used for cutting, resulting in high blade utilization.

[0014] A further feature of this invention is that the pressure roller assembly includes a pressure roller and a pressure roller arm for mounting the pressure roller. The pressure roller is rotatably connected to the pressure roller arm via a pressure roller shaft. The upper end of the pressure roller arm is rotatably connected to a support plate fixed on the machine body. A longitudinal groove is provided at the lower end of the pressure roller wall, and the pressure roller shaft is slidably engaged with the longitudinal groove.

[0015] By adopting the above technical solution, when the log conveying mechanism transports the log to be processed to the processing position, the log first contacts the pressure roller assembly near the feeding side. As the log continues to move, the pressure roller is lifted up, and the pressure roller shaft slides above the longitudinal groove. At this time, the pressure roller presses down on the top of the log under its own weight, so that the two ends of the log will not lift up or roll, thereby achieving the effect of improving the accuracy of log cutting.

[0016] A further feature of this invention is that both the cutting blade and the pressure roller have serrations on their circumferences.

[0017] By adopting the above technical solution, the serrations on the cutting blade are used to quickly cut into the log during high-speed rotation, cutting the log into slices. The serrations on the pressure roller are used to increase the friction between the pressure roller and the log, further reducing the movement of the log during the cutting process, thus further improving the accuracy of log cutting.

[0018] A further feature of this invention is that the log conveying mechanism includes two sets of parallel conveyor belts that rotate synchronously, and the two conveyor belts are connected by multiple V-shaped support seats, the center of which is directly opposite the pressure roller.

[0019] By adopting the above technical solution, the log conveying assembly uses a V-shaped support seat to support and position the logs, making it less likely for the logs to roll or move. The support and positioning accuracy is high, and the stability is good. The V-shaped support seat can also ensure that the center position of the logs is always constant, which is beneficial to ensuring the accuracy of cutting and processing. Moreover, it can adapt to the support and positioning of logs of different diameters, greatly improving the versatility of the equipment.

[0020] A further feature of this invention is that both the upper and lower cutting roller assemblies are provided with a guide assembly on their discharge side. The guide assembly includes a guide roller and a plurality of guide discs evenly spaced on the guide roller. The guide roller is provided with a guide disc spacing adjustment mechanism for automatically adjusting the spacing between the guide discs.

[0021] By adopting the above technical solution, the material guiding component is used to guide the wood chips obtained from the cutting process, so that the wood chips obtained from the cutting process can be discharged smoothly and orderly.

[0022] A further feature of this invention is that the spacing adjustment mechanism between the guide roller and the guide plate is identical in structure to the spacing adjustment mechanism between the cutting blade shaft and the cutting blade.

[0023] By adopting the above technical solution, the guide plate spacing adjustment mechanism is used to synchronously adjust the spacing between each guide plate according to the spacing between the cutting blades, so that the spacing between the guide plate and the cutting blades is matched, which facilitates the guide plate to guide the wood chips obtained from the cutting process, and makes the output effect of the wood chips better.

[0024] A further feature of this invention is that: a wood chip receiving hopper is provided below the log conveying mechanism, a dust cover is provided above the log conveying mechanism, both pressure roller assemblies and the cutting assembly are located inside the dust cover, a feed inlet is provided on the side of the dust cover near the feeding direction, a discharge outlet is provided on the side of the dust cover near the discharge direction, and dust curtains are provided at both the feed inlet and the discharge outlet.

[0025] By adopting the above technical solution, the sawdust receiving hopper is used to receive and collect sawdust generated during the cutting process, preventing sawdust from scattering directly on the ground, which helps maintain the hygiene of the processing environment and reduces the difficulty of manually cleaning sawdust. The dust cover and the dust cover set at the inlet and outlet of the dust cover can isolate the cutting area from the outside world, so that the sawdust generated during the processing will not fly around and injure people. At the same time, it can also effectively prevent the spread of micro-dust generated during the processing into the air, greatly reducing the problem of air pollution in the production workshop and effectively reducing the harm caused by micro-dust in the air to the human body.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model utilizes a log conveying mechanism to transport the logs to be processed to the processing position. The logs pass sequentially through two pressure roller assemblies and the cutting assembly between the two pressure roller assemblies. The two pressure roller assemblies use their own weight to press the logs to be processed onto the log conveying mechanism, preventing the ends of the logs from lifting or rolling during the cutting process, thus effectively ensuring the cutting accuracy. The cutting blade spacing adjustment mechanism on the cutting blade shaft is used to automatically adjust the spacing between adjacent cutting blades on the cutting blade shaft and fix the cutting blades on the cutting blade shaft at a suitable spacing. The cutting blades do not need to be disassembled during the adjustment process, which is not only highly efficient but also safe.

[0028] 2. This utility model uses a cutting drive motor to drive the cutting blade shaft to rotate at high speed, which in turn drives the cutting blades to rotate at high speed, thus realizing the cutting operation. When it is necessary to adjust the spacing between the cutting blades, the adjusting shaft is manually controlled to rotate at a certain angle relative to the cutting blade shaft. When the adjusting shaft rotates, the adjusting block will slide relative to the slide groove on the adjusting shaft. Since the adjacent slide grooves gradually increase or decrease in size, when the adjusting block slides relative to the slide groove on the adjusting shaft, the spacing between the adjusting blocks gradually increases or decreases. This causes the spacing between the cutting blades fixedly connected to each adjusting block to gradually increase or decrease until it matches the preset spacing. Therefore, the spacing adjustment operation between adjacent cutting blades is realized. The operation process is simple and convenient, and the blades do not need to be disassembled during adjustment, making it safe and efficient.

[0029] 3. After the spacing adjustment operation is completed, each cutting blade engages with the adjustment groove and slide groove respectively through the adjustment block. Therefore, during the cutting operation, there will be no relative movement between the cutting blade and the cutting blade shaft. This ensures that the cutting blade shaft and the cutting blade always rotate synchronously at high speed during the high-speed rotation of the cutting blade shaft, effectively avoiding the problem of the shaft rotating but the blade not rotating, which affects the stability of the cutting process.

[0030] 4. In this utility model, the cutting blade spacing adjustment mechanism is set inside the cutting blade shaft, which will not affect the cutting position of the cutting blade. The entire cutting blade can be used for cutting, and the cutting blade utilization rate is high.

[0031] 5. In this utility model, the round log conveying assembly uses a V-shaped support seat to support and position the round logs, making it less likely for the logs to roll or move. The support and positioning accuracy is high, and the stability is good. The V-shaped support seat can also ensure that the center position of the round logs is always constant, which is beneficial to ensuring the accuracy of cutting and processing. Moreover, it can adapt to the support and positioning of round logs of different diameters, greatly improving the versatility of the equipment.

[0032] 6. This utility model guides the wood chips obtained from the cutting process through a material guiding component, so that the wood chips can be discharged smoothly and orderly. The spacing between each material guiding plate is adjusted synchronously according to the spacing between the cutting blades through the material guiding plate spacing adjustment mechanism, so that the spacing between the material guiding plate and the cutting blades is matched, which facilitates the material guiding plate to guide the wood chips obtained from the cutting process, resulting in better wood chip discharge effect.

[0041] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0042] like Figures 1-6 As shown, a horizontal log saw includes a machine body 1, a log conveying mechanism 2 on the machine body 1, two pressure roller assemblies 3 above the log conveying mechanism 2, and a sawing assembly 4 between the two pressure roller assemblies 3. The sawing assembly 4 includes an upper sawing roller assembly and a lower sawing roller assembly. The upper and lower sawing roller assemblies have the same structure, each including a sawing shaft 41 and a plurality of sawing blades 42 equally spaced on the sawing shaft 41. The sawing blades 42 are sleeved on the sawing shaft 41, and a sawing blade spacing adjustment mechanism 5 is provided on the sawing shaft 41 for automatically adjusting the spacing between the sawing blades 42.

[0043] Furthermore, both ends of the cutting blade shaft 41 are rotatably connected to the machine body 1. One end of the cutting blade shaft 41 is connected to the output shaft of the cutting drive motor 43 fixed on the machine body 1. The other end of the cutting blade shaft 41 is provided with an adjustment hole 44 coaxial with the cutting blade shaft 41. The cutting blade spacing adjustment mechanism 5 includes an adjustment shaft 51 disposed in the adjustment hole 44. The adjustment shaft 51 is coaxial with the adjustment hole 44 and threadedly connected.

[0044] Furthermore, the outer wall of the adjusting shaft 51 is provided with a plurality of circumferentially extending grooves 53. The number of grooves 53 matches the number of cutting blades 42. The spacing between adjacent grooves 53 is equal, and the spacing between adjacent grooves 53 shows a trend of gradually increasing or gradually decreasing.

[0045] Furthermore, an adjustment groove 54 is provided on the outer wall of the cutting blade shaft 41. The adjustment groove 54 is parallel to the axial direction of the cutting blade shaft 41 and is connected to the adjustment hole 44. An adjustment block 55 is provided on the inner wall of the cutting blade 42, which can slide along the adjustment groove 54. The adjustment block 55 passes through the adjustment groove 54 and extends into the corresponding sliding groove 53 and slides in cooperation with the sliding groove 53.

[0046] Furthermore, the pressure roller assembly 3 includes a pressure roller 31 and a pressure roller arm 32 for mounting the pressure roller 31. The pressure roller 31 is rotatably connected to the pressure roller arm 32 via a pressure roller shaft 33. The upper end of the pressure roller arm 32 is rotatably connected to a support plate 6 fixed on the machine body 1. The lower end of the pressure roller arm 32 is provided with a longitudinal sliding groove 34, and the pressure roller shaft 33 is slidably engaged with the longitudinal sliding groove 34.

[0047] Furthermore, both the cutting blade 42 and the pressure roller 31 are provided with serrations 7 on their circumferences.

[0048] Furthermore, the log conveying mechanism 2 includes two sets of parallel and synchronously rotating conveyor belts 21, which are connected by multiple V-shaped support seats 22, with the center of the V-shaped support seat 22 facing the pressure roller 31.

[0049] Furthermore, both the upper and lower cutting roller assemblies are provided with a guide assembly 8 on their discharge side. The guide assembly 8 includes a guide roller 81 and a plurality of guide discs 82 arranged at equal intervals on the guide roller 81. The guide roller 81 is provided with a guide disc spacing adjustment mechanism 9 for automatically adjusting the spacing between the guide discs 82.

[0050] Furthermore, the guide roller 81 and the guide plate spacing adjustment mechanism 9 have the same structure as the cutting blade shaft 41 and the cutting blade spacing adjustment mechanism 5.

[0051] Furthermore, a sawdust receiving hopper 10 is provided below the log conveying mechanism 2, and a dust cover 11 is provided above the log conveying mechanism 2. The two pressure roller assemblies 3 and the cutting assembly 4 are both located inside the dust cover 11. The dust cover 11 has a feed inlet 12 on the side near the feeding direction and a discharge outlet 13 on the side near the discharge direction. Dust curtains are provided at both the feed inlet 12 and the discharge outlet 13.

[0052] The working principle of this utility model is as follows: The log to be processed is transported to the processing position by the log conveying mechanism 2. The log passes through the two pressure roller assemblies 3 and the cutting assembly 4 between the two pressure roller assemblies 3 in sequence. The two pressure roller assemblies 3 use their own weight to press the log to be processed onto the log conveying mechanism 2, which prevents the two ends of the log from lifting or rolling during the cutting process, thus effectively ensuring the cutting accuracy. The cutting blade spacing adjustment mechanism 5 on the cutting blade shaft 41 is used to automatically adjust the spacing between adjacent cutting blades on the cutting blade shaft 41 and fix the cutting blades on the cutting blade shaft 41 at a suitable spacing. The cutting blades do not need to be disassembled during the adjustment process, which is not only efficient but also safe.

[0053] When it is necessary to adjust the spacing between adjacent cutting blades on the cutting blade shaft 41, the adjusting shaft 51 is manually rotated at a certain angle relative to the cutting blade shaft 41. When the adjusting shaft 51 rotates, the adjusting block 55 slides relative to the slide groove 53 on the adjusting shaft 51. Since the adjacent slide grooves 53 gradually increase or decrease in size, when the adjusting block 55 slides relative to the slide groove 53 on the adjusting shaft 51, the spacing between the adjusting blocks 55 gradually increases or decreases. This causes the spacing between the cutting blades 42 fixedly connected to each adjusting block 55 to gradually increase or decrease until it matches the preset spacing. Thus, the spacing adjustment operation between adjacent cutting blades 42 is realized. The operation is simple and convenient, and the blades do not need to be disassembled during adjustment, making it safe and efficient.

[0054] After the spacing adjustment operation is completed, each cutting blade 42 is engaged with the adjustment groove 54 and the slide groove 53 respectively through the adjustment block 55. Therefore, during the cutting operation, there will be no relative movement between the cutting blade 42 and the cutting blade shaft 41, thereby ensuring that the cutting blade shaft 41 and the cutting blade 42 always rotate synchronously at high speed during the high-speed rotation of the cutting blade shaft 41, effectively avoiding the problem of the shaft rotating but the blade not rotating, which affects the stability of the cutting process.

[0055] In addition, since the cutting blade spacing adjustment mechanism 5 is located inside the cutting blade shaft 41, it will not affect the cutting position of the cutting blade 42. The entire cutting blade 42 can be used for cutting, and the cutting blade 42 has a high utilization rate.

[0056] The material guiding assembly 8 is used to guide the wood chips obtained from the cutting process, so that the wood chips can be discharged smoothly and orderly. The material guide plate spacing adjustment mechanism 9 is used to synchronously adjust the spacing between each material guide plate 82 according to the spacing between the cutting blades 42, so that the spacing between the material guide plate and the cutting blades 42 is matched, which facilitates the material guide plate to guide the wood chips obtained from the cutting process, and makes the output effect of the wood chips better.
