Description

Technical Field

[0001] This utility model relates to the technical field of wood chisel production equipment, and in particular to a wood chisel cleaning machine. Background Technology

[0002] In the large-scale production of wood chisels, finished products must undergo a rigorous cleaning process before packaging to ensure they are delivered to consumers in a clean and intact state. Cleaning the wooden handles is a key and challenging aspect of this process. After grinding and polishing, the surface and deep within the wood grain of the handle will retain a large amount of fine wood dust, sanding powder, and stains from the operator's hands. If these residues are not removed, they will directly affect the product's appearance and grip.

[0003] Currently, the tool manufacturing industry generally lacks specialized equipment for the final cleaning of wood chisel handles. Manufacturers typically use manual methods, such as blowing with an air gun and wiping with cloths, or directly placing the entire chisel into a general-purpose vibratory cleaner or brush cleaner. The former is not only inefficient and the cleaning effect depends on the worker's experience, but the dust it generates is also unfriendly to the workshop environment; the latter, while having a certain degree of automation, was not designed for the special shape of a wood chisel, which has a heavy object (metal chisel head) on one end and a light wooden handle on the other. General fixing and cleaning methods cannot prevent the wood chisels from colliding with each other in the cleaning chamber, causing secondary damage such as scratches and dents on the surface of the wooden handle, which in turn reduces the product yield.

[0004] Therefore, there is an urgent need in the existing technology for an automated cleaning device that can be integrated into the end of the production line and is specifically designed for the handle of wood chisels. This device should be able to complete the cleaning task efficiently and stably without damaging the wooden handle and the metal chisel head. Utility Model Content

[0005] Purpose of the invention: The purpose of this utility model is to provide a wood chisel cleaning machine that achieves precise positioning of the cleaning action by accurately aligning the spray head of the cleaning mechanism with the wood chisel handle fixed by the clamp assembly. The transmission mechanism drives the handle to pass through the spray station in sequence, completely replacing inefficient and unstable manual operation, and significantly improving the cleaning efficiency and consistency of the production line.

[0006] Technical solution:

[0007] A wood chisel cleaning machine includes a frame, a transmission mechanism, and a cleaning mechanism. The transmission mechanism includes a lead screw assembly, a moving block cooperating with the lead screw assembly, and a clamp assembly for fixing the wood chisels. The clamp assembly is rotatably connected to the moving block via a rotating shaft, and the bottom of the clamp assembly is provided with a contour positioning groove for accommodating and positioning the wood chisel head. The cleaning mechanism includes a spray head disposed toward the clamp assembly and a rotary drive device coupled to the rotating shaft and driving the clamp assembly to rotate around the axis of the rotating shaft.

[0008] Furthermore, the rotary drive device is a rack fixed to the frame, and a gear that meshes with the rack is fixedly mounted on the rotating shaft.

[0009] Furthermore, the contour positioning groove is composed of a front elongated area for accommodating the chisel head and a rear circular area for holding the connecting end of the wooden chisel. The bottom of the contour positioning groove is provided with an opening, and the chisel handle is exposed at the upper end of the contour positioning groove.

[0010] Furthermore, the lead screw assembly and the moving block are located in the dry area of ​​the frame, while the clamp assembly and the cleaning mechanism are located in the wet area of ​​the frame. The two are separated by a partition, and a guide groove for the rotating shaft to pass through is provided in the middle of the partition.

[0011] Furthermore, the lead screw assembly includes a second motor, a lead screw driven by the second motor, and the moving block is threadedly engaged with the lead screw.

[0012] Furthermore, the lead screw assembly also includes a slider slidably connected in the guide groove, the slider being rotatably connected to the rotating shaft.

[0013] Furthermore, it also includes a drying mechanism, which includes a hot air drying device disposed downstream of the cleaning mechanism.

[0014] Furthermore, multiple clamp assemblies are equidistantly arranged, and multiple moving blocks are correspondingly arranged.

[0015] Beneficial effects:

[0016] 1. This utility model achieves precise positioning of the cleaning action by accurately aligning the spray head of the cleaning mechanism with the wooden chisel handle fixed by the clamp assembly. The transmission mechanism drives the handle to pass through the spray station in sequence, completely replacing inefficient and unstable manual operation, and significantly improving the cleaning efficiency and consistency of the production line.

[0017] 2. The metal chisel head is precisely fixed by the contour positioning groove, so that the entire wooden handle is in a stable state of being completely suspended and exposed. This fundamentally avoids scratches on the wooden handle and damage to the chisel head edge caused by the collision of tools on the cleaning line, ensuring the perfect appearance of the finished product when it leaves the factory.

[0018] 3. The rotary drive unit drives the clamp assembly and wood chisel to rotate around the axis, so that the entire circumference of the wood handle can be effectively covered and rinsed by the cleaning liquid from the spray head, thoroughly removing stubborn dust deep in the wood grain and in any corners and crevices. This is an effect that traditional fixed cleaning cannot achieve.

[0019] 4. The dry and wet separation structure isolates the precision transmission components from the cleaning area, ensuring long-term stable operation of the equipment in humid industrial environments. Simultaneously, this design allows the device to be directly integrated into existing production lines, processing only the handle area without requiring modifications to preceding production processes, making it highly practical.

[0020] 5. The configuration of multiple clamp assemblies enables the device to continuously and sequentially clean multiple wooden chisels, forming a highly efficient cleaning production line that directly matches the pace of modern production and significantly improves the overall capacity of pre-packaging processing.

[0026] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figure 1-5As shown, a wood chisel cleaning machine includes a frame 1, a transmission mechanism 2, and a cleaning mechanism 3. The transmission mechanism 2 includes a lead screw assembly 21, a moving block 22 cooperating with the lead screw assembly 21, and a clamp assembly 23 for fixing the wood chisels. The clamp assembly 23 is rotatably connected to the moving block 22 via a rotating shaft 231, and the bottom of the clamp assembly 23 is provided with a contour positioning groove 232 for accommodating and positioning the wood chisel head. The cleaning mechanism 3 includes a spray head 31 facing the clamp assembly 23 and a rotary drive device 32 coupled to the rotating shaft 231 and driving the clamp assembly 23 to rotate around the axis of the rotating shaft 231. The transmission mechanism 2 is responsible for driving the clamp assembly 23 to perform linear motion, while the cleaning mechanism 3 is responsible for performing cleaning actions at specific workstations. Its core function is to achieve automated conveying and cleaning of wood chisels on the production line through the coordination of transmission and cleaning.

[0029] Furthermore, the rotary drive device 32 is a rack fixed to the frame 1, and a gear 233 meshing with the rack is fixedly mounted on the rotating shaft 231. This structure provides a simple and reliable rotary drive method. When the moving block 22 drives the gear 233 on the rotating shaft 231 past the fixed rack, the gear 233 is forced to rotate, thereby transmitting the rotation to the clamp assembly 23 and the wood chisel through the rotating shaft 231. Its function is to achieve uniform rotation of the wood chisel at the cleaning station, ensuring that the surface of the wood handle can be evenly covered by the cleaning liquid, achieving a cleaning effect without dead angles.

[0030] Furthermore, the contour positioning groove 232 is composed of a front elongated area for accommodating the chisel head and a rear circular area for holding the connecting end of the chisel. The bottom of the contour positioning groove 232 has an opening, and the chisel handle protrudes from the upper end of the groove. The contour positioning groove 232 utilizes the geometric features of the chisel itself, restricting the movement of the chisel head through the front elongated area and holding the connecting end in the rear circular area, thus achieving complete positioning of the chisel in both the horizontal and circumferential directions. The bottom opening ensures that the chisel handle is completely exposed, creating the necessary conditions for thorough cleaning of the handle.

[0031] Furthermore, the lead screw assembly 21 and the moving block 22 are located in the dry area of ​​the frame 1, while the clamp assembly 23 and the cleaning mechanism 3 are located in the wet area of ​​the frame 1. The two are separated by a partition 11, in the middle of which is a guide groove 12 for the rotating shaft 231 to pass through. This structure forms a crucial dry and wet separation protection. The partition 11 divides the equipment into two independent chambers, with the upper dry area protecting the precision lead screw drive system from the moisture and cleaning fluid in the lower wet area. The guide groove 12, while ensuring the normal movement of the rotating shaft 231, also minimizes the upward diffusion of the wet medium, thereby significantly improving the service life of the core transmission components and the reliability of the equipment.

[0032] Furthermore, the lead screw assembly 21 includes a second motor 211 and a lead screw 212 driven by the second motor 211, with the moving block 22 threadedly engaged with the lead screw 212. The second motor 211 serves as a power source, driving the lead screw 212 to rotate. The moving block 22, which engages with the lead screw 212 via a threaded pair, converts the rotational motion of the lead screw 212 into its own precise linear motion. Its function is to achieve precise positioning and reliable transfer of the fixture assembly 23 between different workstations.

[0033] Furthermore, the lead screw assembly 21 also includes a slider 213 slidably connected within the guide groove 12, and the slider 213 is rotatably connected to the rotating shaft 231. The slider 213 is connected to the moving block 22 and slides within the guide groove 12, effectively bearing the overturning torque generated by the clamp assembly 23 and the wooden chisel. Its function is to ensure smooth movement of the entire moving part, preventing jamming or shaking, while simultaneously transmitting the force on the rotating shaft 231 to the partition plate 11.

[0034] Furthermore, the system also includes a drying mechanism 4, which comprises a hot air drying device located downstream of the cleaning mechanism 3. The drying mechanism 4 constitutes the final stage of the cleaning process. It utilizes heated air generated by the hot air drying device 41 to blow on the cleaned wooden chisel handles. This accelerates the evaporation of moisture from the surface of the handles, allowing them to dry quickly and ensuring that the chisels can directly enter the packaging process after cleaning, avoiding quality problems caused by damp handles.

[0035] Furthermore, multiple clamp assemblies 23 are equidistantly arranged, and multiple moving blocks 22 are correspondingly arranged.

[0036] In other embodiments of this utility model, the conveying method of the transmission mechanism 2 is not limited to the screw assembly 21, but can also employ synchronous belt drive assembly, chain drive assembly, or ring guide rail assembly capable of cyclic conveying. When cyclic conveying is used, multiple clamp assemblies 23 can be fixed at equal intervals on the ring conveying line and driven by the drive device to perform continuous cyclic motion, sequentially passing through the loading, cleaning, drying, and unloading stations. Compared with the reciprocating motion of the screw assembly, cyclic conveying eliminates the empty return stroke, allowing the equipment to process more wood chisels per unit time, significantly improving production efficiency. This layout is particularly suitable for large-scale, continuous production cycles. The clamp assembly 23 circulates on the ring line, enabling parallel operation of each station and making the production process smoother. The screw assembly in this embodiment is suitable for small-scale cleaning.

[0037] During operation, the operator inserts the chisel head into the contour positioning groove 232 of the clamp assembly 23 for fixation. After starting the equipment, the second motor 211 drives the lead screw 212 to rotate, causing the moving block 22 and the clamp assembly 23 to move step by step from the loading station to the cleaning station. When the clamp assembly 23 enters the cleaning station, the gear 233 on the rotating shaft 231 meshes with the fixed rack on the frame 1, driving the clamp assembly 23 and the chisel to rotate at a uniform speed. At the same time, the spray head 31 sprays cleaning fluid onto the rotating wooden handle, achieving thorough cleaning. After cleaning, the moving block 22 continues to move to the drying station, where the hot air drying device 41 dries the wooden handle. Finally, the moving block 22 carries the clean and dry chisel to the unloading station, completing one work cycle. If multiple clamp assemblies 23 are configured, continuous batch cleaning can be achieved.

[0038] The embodiments described above are merely illustrative of certain implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
