Technical Problem

现有采用卷尺测量原木的长度和直径时,需要人员在原木两端来回走动才能对原木的长度和直径进行测量,存在测量效率低及数据难以记录的问题,并且,在测量时还需一根根的人工上料,费时费力、效率低下且容易出现工伤事故,不利于安全生产

Benefits of technology

通过上料结构的设计,在使用时,将若干原木从上至下依次放置到上料腔内,原木会先竖向堆满上料腔,然后横向堆满储料腔形成一个倾斜式L型堆放结构,在这个过程中,因为上料腔和储料腔的厚度限制,即使空间比原木略宽也不会出现双层堆积的现象,上述L型堆放结构均是单层堆放,而,因为上料通道的空间大小也只够一根原木放置的,所以,每次上料通道内也只有一根原木,在物料准备完成后,进行检测时,通过电控箱启动上料气缸,上料气缸通过推板和若干呈倾斜集束状的导向凸条相互作用,进而可以推动原木稳定移动到传送带上。

Description

Technical Field

[0001] This utility model is a log measuring machine, belonging to the field of log measurement technology. Background Technology

[0002] When processing or selling timber, logs need to be measured to determine their length and diameter for estimating volume and sorting. Currently, using a measuring tape requires personnel to walk back and forth between the logs, resulting in low efficiency and difficulty in data recording. Furthermore, manual loading of each log is time-consuming, labor-intensive, inefficient, and prone to workplace accidents, posing a safety hazard. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a log measuring machine.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A log measuring machine includes a feeding structure and a measuring mechanism. The feeding structure includes a feeding frame and a material box. The material box has a storage cavity connected to a feeding channel on the feeding frame. A feeding cylinder with its output end extending into the feeding channel is installed on one side of the feeding frame. A push plate is installed on the output end of the feeding cylinder. The storage cavity is located in the middle of one side of the material box. A feeding cavity extending to the top of the material box is located on one side of the top of the storage cavity.

[0005] Furthermore, the measuring mechanism includes a conveyor belt located at the discharge end of the feeding channel. Several fixed frames are fixedly installed on both sides of the conveyor belt. Clamping cylinders are installed on the fixed frames, and clamping plates are installed on the side output ends of the clamping cylinders. A lead screw slide rail assembly is installed on the support frame of the conveyor belt. The lead screw output end of the lead screw slide rail assembly is connected to a servo motor. An electric push rod is installed at the bottom of the lead screw slider on the lead screw slide rail assembly. A distance measuring wheel is installed at the bottom telescopic end of the electric push rod.

[0006] Furthermore, the measuring mechanism also includes a second screw slide rail assembly disposed on the side of the conveyor belt away from the loading frame. The screw output end of the second screw slide rail assembly is connected to a second servo motor. An electric push rod is installed at the bottom of the second screw slider on the second screw slide rail assembly. A support plate is installed at the bottom telescopic end of the electric push rod. A distance measuring wheel is installed on the outer surface of the support plate near the first screw slide rail assembly.

[0007] Furthermore, the outer surface of the conveyor belt is provided with a rubber damping strip, which has a cross-shaped structure.

[0008] Furthermore, a collection chamber is provided inside the material box and below the storage chamber. A plurality of mesh holes are provided between the top of the collection chamber and the bottom of the storage chamber. A discharge port communicating with the collection chamber is provided on one side of the outer surface of the material box. A material collection drawer is installed in the discharge port and is installed inside the collection chamber and below the mesh holes.

[0009] Furthermore, a number of guide protrusions are installed on the inner wall of the feeding channel, and the inclination direction of the number of guide protrusions is located on the side of the feeding channel closer to the measuring mechanism.

[0010] Furthermore, an electrical control box is installed on one side of the material box. The electrical control box contains a power supply and a controller. A control switch is provided on the outer surface of the electrical control box. The controller is electrically connected to the feeding cylinder, the conveyor belt, the clamping cylinder, the first servo motor, the first electric push rod, the first measuring wheel, the second servo motor, the second electric push rod, and the second measuring wheel.

[0011] The beneficial effects of this utility model are: Through the design of the feeding structure, during use, several logs are placed into the feeding chamber from top to bottom. The logs will first be stacked vertically to fill the feeding chamber, and then horizontally to fill the storage chamber, forming an inclined L-shaped stacking structure. During this process, due to the thickness limitations of the feeding chamber and the storage chamber, even if the space is slightly wider than the logs, there will be no double-layer stacking. The above-mentioned L-shaped stacking structure is all single-layer stacking. Since the space of the feeding channel is only large enough for one log, there is only one log in the feeding channel at a time. After the material preparation is completed, when testing is performed, the feeding cylinder is started through the electrical control box. The feeding cylinder interacts with the push plate and several inclined bundled guide convex strips, which can then push the logs to move stably onto the conveyor belt.

[0012] Through the design of the measuring mechanism, the conveyor belt starts and carries the log to the designated position. Then, several clamping cylinders are activated from both sides of the log, and the log is stably clamped by clamping plates. After the log is clamped and fixed, the measuring mechanism is activated to detect the length and diameter of the log. Specifically, the first servo motor is started through the electrical control box. The first servo motor drives the lead screw on the lead screw slide rail assembly to rotate. The lead screw drives the lead screw slider to move through the thread. The lead screw slider moves the electric push rod and the measuring wheel to the end position of the log. Then, the electric push rod is activated, which drives the measuring wheel to descend to the outer surface of the log. Next, the first servo motor is activated again, which drives the measuring wheel to move linearly on the outer surface of the log. After the movement is completed, the data measured by the measuring wheel is transmitted to the electrical control box for display. At this time, the length of the log is detected. Then, the same process is repeated to start the second servo motor and the second electric push rod, which drive the second measuring wheel to move linearly to the center position of the log to measure the diameter of the log. This completes the measuring of the log.

[0013] The clustered inclined design of the guide ridges can act as a guide when the logs fall from the storage chamber into the feeding channel and are pushed towards the measuring mechanism by the feeding cylinder through the push plate, thus preventing the logs from tilting or swaying.

[0014] By incorporating rubber damping strips, the friction between the logs and the transmission belt is increased, thereby enhancing the stability of the logs and reducing the occurrence of accidents during the testing process.

[0015] By using a collection chamber and mesh, as the logs fall vertically from the feeding chamber into the storage chamber and roll within the storage chamber, dust and sawdust on their outer surface fall through the mesh into the collection drawer inside the collection chamber. The rolling of the logs then squeezes and pushes the debris in the storage chamber, achieving a cleaning effect. Attached Figure Description

[0019] 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 protection scope of the present utility model.

[0020] Please see Figures 1-5This utility model provides a technical solution for a log measuring machine, including a feeding structure and a measuring mechanism. The feeding structure includes a feeding frame 1 and a material box 2. The material storage cavity 6 on the material box 2 is connected to the feeding channel 3 on the feeding frame 1. A feeding cylinder 4 with its output end extending into the feeding channel 3 is installed on one side of the feeding frame 1. A push plate 5 is installed on the output end of the feeding cylinder 4. A plurality of guide protrusions 25 are installed on the inner wall of the feeding channel 3. The inclined direction of the plurality of guide protrusions 25 is located on the side of the feeding channel 3 closer to the measuring mechanism. Through the clustered inclined design of the guide protrusions 25, the measuring mechanism can be... After the logs fall from the storage chamber 6 into the feeding channel 3, the feeding cylinder 4, through the push plate 5, moves the logs towards the measuring mechanism, acting as a guide to prevent the logs from tilting or swaying. The storage chamber 6 is located in the middle of one side of the material box 2. A feeding chamber 9, extending through to the top of the material box 2, is located on one side of the storage chamber 6. An electrical control box is installed on one side of the material box 2, containing a power supply and controller. A control switch is located on the outer surface of the electrical control box. The controller is connected to the feeding cylinder 4, the conveyor belt 10, the clamping cylinder 13, and the servo motor 16. The electric push rod 18, the distance measuring wheel 19, the servo motor 21, the electric push rod 2, and the distance measuring wheel 24 are electrically connected. This electrical connection can be a wired connection using a cable and cable chain, a wireless connection between a wireless signal transceiver and a power supply, or other existing connection methods. Furthermore, the distance measuring wheel and electrical control box used in this technical solution are all existing devices, and therefore will not be described in detail. Through the design of the feeding structure, during use, several logs are placed sequentially from top to bottom into the feeding chamber 9. The logs will first vertically fill the feeding chamber 9, and then... The material is then horizontally stacked to fill the storage chamber 6, forming an inclined L-shaped stacking structure. During this process, due to the thickness limitations of the feeding chamber 9 and the storage chamber 6, even if the space is slightly wider than the logs, there will be no double-layer stacking. The above-mentioned L-shaped stacking structures are all single-layer stacking. Since the space of the feeding channel 3 is only large enough for one log, there is only one log in the feeding channel 3 each time. After the material preparation is completed, when the inspection is carried out, the feeding cylinder 4 is started through the electrical control box. The feeding cylinder 4 interacts with the push plate 5 and several inclined bundled guide convex strips 25, which can then push the logs to move stably onto the conveyor belt 10.

[0021] See Figure 1 , Figure 3 and Figure 5The measuring mechanism includes a conveyor belt 10 located at the discharge end of the feeding channel 3. Several fixed frames 12 are fixedly installed on both sides of the conveyor belt 10. Clamping cylinders 13 are mounted on the fixed frames 12, and clamping plates 14 are installed on the side output ends of the clamping cylinders 13. A lead screw slide rail assembly 15 is mounted on the support frame of the conveyor belt 10. The lead screw output end of the lead screw slide rail assembly 15 is connected to a servo motor 16. An electric push rod is installed at the bottom of the lead screw slider 17 on the lead screw slide rail assembly 15. The electric push rod 18 has a measuring wheel 19 installed at its bottom telescopic end. The measuring mechanism also includes a screw slide rail assembly 20 located on the side of the conveyor belt 10 away from the loading rack 1. The screw output end of the screw slide rail assembly 20 is connected to a servo motor 21. The bottom of the screw slider 22 on the screw slide rail assembly 20 is equipped with an electric push rod 2. The bottom telescopic end of the electric push rod 2 is equipped with a support plate 23. The outer surface of the support plate 23 near the screw slide rail assembly 15 is equipped with a measuring wheel 24. Through the design of the measuring mechanism, the conveyor belt 10 starts and drives the log to the designated position. Then, several clamping cylinders 13 are activated from both sides of the log, and the log is stably clamped by the clamping plate 14. After the log is clamped and fixed, the measuring mechanism is activated to detect the length and diameter of the log. Specifically, the servo motor 16 is first started through the electrical control box. The servo motor 16 drives the lead screw on the lead screw slide rail assembly 15 to rotate. The lead screw drives the lead screw slider 17 to move through the thread. The lead screw slider 17 drives the electric push rod 18 and the measuring wheel 19 to move to the log. At the end position, the electric push rod 18 is started, driving the measuring wheel 19 down to the outer surface of the log. Then, the servo motor 16 is started again, driving the measuring wheel 19 to move in a straight line on the outer surface of the log. After the movement is completed, the data measured by the measuring wheel 19 is transmitted to the control box for display. At this time, the length of the log is detected. Then, the servo motor 21 and the electric push rod 2 are started in the same way, driving the measuring wheel 24 to move in a straight line at the center position of the log, and the diameter of the log is measured. The measurement of the log is then completed.

[0022] See Figure 1 The outer surface of the conveyor belt 10 is provided with a rubber damping strip 11, which has a cross-shaped structure. By setting the rubber damping strip 11, the friction between the log and the conveyor belt 10 is increased, the stability of the log is improved, and the occurrence of accidents during the inspection process is reduced.

[0023] See Figures 1-2A collection chamber 7 is provided inside the material box 2 and below the storage chamber 6. Several mesh holes 8 are provided between the top of the collection chamber 7 and the bottom of the storage chamber 6. A discharge port connected to the collection chamber 7 is provided on one side of the outer surface of the material box 2. A collection drawer is installed in the discharge port and is installed inside the collection chamber 7 and below the mesh holes 8. With the setting of the collection chamber 7 and the mesh holes 8, when the logs fall vertically from the loading chamber 9 to the storage chamber 6 and roll in the storage chamber 6, the dust and wood chips on their outer surface will fall into the collection drawer inside the collection chamber 7 through the mesh holes 8. The rolling of the logs will squeeze and push the debris in the storage chamber 6, achieving the effect of pushing and cleaning.

[0024] The circuits and electronic components, modules and controllers, or the heat dissipation holes and maintenance doors in the space of the adapted electrical equipment are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this application does not involve improvements to software and methods or heat dissipation and maintenance.

[0025] In use, several logs are placed into the feeding chamber 9 from top to bottom. The logs will first be stacked vertically to fill the feeding chamber 9, and then horizontally to fill the storage chamber 6, forming an inclined L-shaped stacking structure. During this process, due to the thickness limitations of the feeding chamber 9 and the storage chamber 6, even if the space is slightly wider than the logs, there will be no double-layer stacking. The above-mentioned L-shaped stacking structure is a single-layer stacking. Since the space of the feeding channel 3 is only large enough for one log, there is only one log in the feeding channel 3 at a time. After the material preparation is completed, when testing is performed, the feeding cylinder 4 is started through the electrical control box. The feeding cylinder 4 interacts with the push plate 5 and several inclined bundled guide convex strips 25, which can then push the logs to move stably onto the conveyor belt 10. Subsequently, the conveyor belt 10 starts and carries the logs to the designated position. Then, several clamping cylinders 13 are started from both sides of the logs, and the logs are stably clamped by the clamping plates 14. After the logs are clamped and fixed, the testing is started. The measuring mechanism detects the length and diameter of the log. First, the servo motor 16 is started via the electrical control box. The servo motor 16 drives the lead screw on the lead screw slide rail assembly 15 to rotate. The lead screw drives the lead screw slider 17 to move via the thread. The lead screw slider 17 drives the electric push rod 18 and the measuring wheel 19 to the end position of the log. Then, the electric push rod 18 starts, driving the measuring wheel 19 to descend to the outer surface of the log. Next, the servo motor 16 starts again, driving the measuring wheel 19 to move linearly on the outer surface of the log. After the movement is completed, the data measured by the measuring wheel 19 is transmitted to the electrical control box for data display. At this point, the length of the log is detected. Then, the same process is repeated, starting the servo motor 21 and the electric push rod 2, driving the measuring wheel 24 to move linearly at the center position of the log to measure the diameter. After the test is completed, the conveyor belt 10 starts again, transporting the log to the transfer conveyor belt in the subsequent process for material transfer.

[0026] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
