Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to a carving water spray cooling device to prevent wood from cracking. Background Technology

[0002] Wood carving is a traditional craft that blends skill and aesthetics, widely used in furniture making, handicraft creation, and other fields. It uses natural wood as raw material, employing carving tools to cut and shape the wood, resulting in rich textures and forms. During the carving process, the techniques must be adjusted according to the characteristics of the wood to better present the design effect, while also paying attention to protecting the wood to ensure the finished product is both beautiful and durable.

[0003] Utility model patent CN221623436U discloses a carving structure for wood carving. This structure includes a carving platform on which a wood board is placed, a bracket mounted on the carving platform, a cylinder mounted on the bracket, and a carving head mounted on the cylinder. The output shaft of the cylinder is fixedly connected to a support plate. The other end of the support plate is connected to a rotating mechanism, and the other end of the rotating mechanism is connected to a connecting component. The other end of the connecting component is connected to a pressure rod, the other end of which abuts against the upper surface of the wood board. This carving structure, by setting the rotating mechanism, connecting mechanism, and pressure rod on one side of the cylinder and carving head, ensures that when the user carves the wood board on the carving platform using a carving machine, the pressure rod located on one side of the carving head will always press against the surface of the wood board on the carving platform, preventing it from shaking.

[0004] The carving structure used for wood carving only uses a pressure bar and ball bearings to press down and limit the wood board to prevent it from shaking during carving. However, it does not have a corresponding structure to address the problem of moisture loss caused by heat generated during the carving process. It cannot cool and moisturize the carving area. During continuous carving, the wood is prone to cracking due to local temperature rise and excessive moisture evaporation, which affects the quality of the finished carving. In view of this, we propose a carving water spray cooling device to prevent wood cracking. Utility Model Content

[0005] The purpose of this invention is to provide a carving water spray cooling device to prevent wood from cracking, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A carving water-cooling device to prevent wood from cracking includes a machine base, a frame on the machine base, a machine head mounted on the frame, and a spraying mechanism mounted on the outer end face of the machine head. The spraying mechanism includes a fixed seat fixed to the machine head, a spraying seat detachably mounted on the fixed seat, and a locking rod for locking the spraying seat.

[0008] The outer end of the fixed base is provided with a protrusion, and an insertion hole is opened on the outer end face of the protrusion. Several locking grooves are opened on the inner wall of the insertion hole.

[0009] The spray seat has a protruding post at the front end, and a plug-in post at the front end of the protruding post. The shape of the plug-in post matches the shape of the plug hole. A cavity is opened at the rear end face of the spray seat. The end of the cavity extends into the plug-in post. Several sleeve holes corresponding to the positions of the locking grooves are opened on the cavity wall. Locking steel balls are fitted in the sleeve holes. A pipe connector is installed at the right end face of the spray seat. A bamboo tube is connected to the bottom end of the spray seat.

[0010] The locking rod has a sliding rod at its head end, which extends into the cavity and slides in connection with it. The sliding rod also has an end rod at its head end, and a tapered pushing part is provided at the connection between the end rod and the sliding rod. When the sliding rod is pushed inward along the axis of the cavity, the pushing part pushes the locking steel ball, causing the locking steel ball to extend from the outer end of the sleeve hole into the locking groove, thereby achieving the purpose of locking the plug-in column.

[0011] Preferably, the fixing seat is installed on the side end face of the machine head by bolts. The cross-section of the insertion hole and the insertion post is square. The insertion post is square columnar. There are four sleeve holes, which are distributed on the four side end faces of the insertion post.

[0012] In this setup, bolt installation ensures the mounting base is stable and easy to install and remove, the square anti-plug post rotates relative to the socket, and the four sleeve holes lock from four directions to improve connection reliability.

[0013] Preferably, the sleeve hole is connected to the cavity, the sleeve hole has a conical hole structure, and the diameter of the sleeve hole gradually decreases in the direction of gradually moving away from the cavity. The minimum diameter of the sleeve hole is smaller than the diameter of the locking steel ball to prevent the locking steel ball from falling out of the sleeve hole.

[0014] In this design, the connecting structure ensures that the pushing part can contact and lock the steel ball, the tapered hole guides the movement of the steel ball, and the minimum hole diameter design prevents the steel ball from falling out.

[0015] Preferably, the minimum distance between the inner wall of the pushing part and the outer wall of the insertion post is less than the diameter of the locking steel ball, so that when the sliding rod moves inward along the cavity until the sliding rod partially covers the inner end of the sleeve hole, the locking steel ball is completely squeezed into the sleeve hole by the sliding rod. At this time, the outer end of the locking steel ball protrudes outward from the outer port of the sleeve hole.

[0016] In this design, the spacing ensures that the pushing part can effectively squeeze the steel ball, causing the steel ball to extend out of the sleeve hole and embed into the locking groove, thus achieving stable locking.

[0017] Preferably, the bottom of the spray seat is provided with a water passage hole connecting the root of the bamboo tube and the pipe joint. The pipe joint, the water passage hole and the bamboo tube are connected. A pipe is installed on the pipe joint and the pipe is connected to an external water source.

[0018] In this setup, the water passages create a complete water path, ensuring that water is delivered from the pipe joint to the bamboo joint pipe, providing conditions for water spraying and cooling in the carving area.

[0019] Preferably, the diameter of the locking rod is smaller than that of the sliding rod, a spring is provided on the outer sleeve of the locking rod, a cover plate is installed on the end face of the spray seat, the locking rod passes through the cover plate and is slidably connected to the cover plate, the first end of the spring abuts against the inner end of the cover plate, the end of the spring abuts against the end of the sliding rod, and the spring is in a compressed state.

[0020] In this setup, the difference in rod diameter provides installation space for the spring, the compression spring pushes the sliding rod to maintain a locking tendency, and the cover plate prevents dust and provides support for the spring.

[0021] Preferably, the diameter of the end rod is smaller than the diameter of the sliding rod, and the radius difference between the end rod and the sliding rod is smaller than the diameter of the locking steel ball, to prevent the locking steel ball from rolling out from the inner end of the sleeve hole. The pushing part is smoothly connected between the sliding rod and the end rod. When the sliding rod is pushed outward along the cavity axis so that the position of the inner end of the sleeve hole is aligned with the end rod, the locking steel ball can retract into the sleeve hole. At this time, the insertion post and the boss are in the unlocked state.

[0022] In this design, the end rod diameter provides space for the steel ball to retract, the radius difference prevents the steel ball from falling out, and the smooth push part makes the unlocking operation easier.

[0023] Preferably, a lever is bolted to the end of the locking rod, the diameter of which is larger than the diameter of the locking rod, and the lever is used to move the locking rod.

[0024] In this setup, the bolt installation facilitates the disassembly and assembly of the lever, and the larger diameter makes it easier for operators to move the locking lever, improving operational convenience.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 1. This wood-crack-preventing carving water-cooling device, through its spray mechanism, enables the device to precisely spray water onto the carving area during the carving process. This cools the carving area while replenishing the wood's moisture, reducing the risk of cracking caused by heat from cutting and moisture loss, and ensuring the integrity of the finished carving.

[0027] 2. This wood-crack-preventing carving water-cooling device features a quick-release locking structure between the fixed base and the spray base, allowing the spray mechanism to be freely installed or disassembled according to carving needs. This facilitates quick removal when water cooling is not required and rapid assembly when needed, enhancing the flexibility of the device. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0037] Please see Figures 1-5A carving water-cooling device for preventing wood cracking includes a machine base 100, a frame 110 on the machine base 100, a machine head 120 mounted on the frame 110, and a spraying mechanism 200 mounted on the outer end face of the machine head 120. The spraying mechanism 200 can spray water to cool the carving area in a targeted manner, reducing the cracking of wood caused by the heat generated during carving. The spraying mechanism 200 includes a fixed seat 210 fixed on the machine head 120, a spraying seat 220 detachably mounted on the fixed seat 210, and a locking rod 230 for locking the spraying seat 220. A pipe connector 225 is installed on the right end face of the spray base 220. The pipe connector 225 can be stably connected to an external water source pipe to provide a water interface for water spraying. A bamboo tube 226 is connected to the bottom of the spray base 220. The bamboo tube 226 can be flexibly bent and shaped to facilitate adjustment of the water spray direction to align with the carving area. A water passage hole is opened at the bottom of the spray base 220 to connect the root of the bamboo tube 226 and the pipe connector 225. The pipe connector 225, the water passage hole and the bamboo tube 226 are connected. A pipe is installed on the pipe connector 225, which is connected to an external water source. The water passage hole provides a flow channel for water flow to ensure that water can be delivered from the pipe connector 225 to the bamboo tube 226.

[0038] like Figures 3-5 As shown, in this utility model, the fixing seat 210 is installed on the side end face of the machine head 120 by bolts. The outer end of the fixing seat 210 is provided with a protrusion 211, which provides a carrier for the insertion hole 212 and enhances the structural strength of the connection between the fixing seat 210 and the spray seat 220. The outer end face of the protrusion 211 is provided with an insertion hole 212, and the cross-section of the insertion hole 212 is square. The first end of the spray seat 220 is provided with a protruding post 221, which can increase the contact area when the spray seat 220 is connected to the fixing seat 210 and improve the connection stability. The first end of the protruding post 221 is provided with a plug-in post 222, which is a square column structure with a square cross-section. The shape of the plug-in post 222 matches the shape of the insertion hole 212. The square structure of the plug-in post 222 and the insertion hole 212 cooperate to prevent relative rotation between the two and ensure the positional stability of the spray seat 220 after installation.

[0039] like Figures 2-5As shown, specifically, a cavity 223 is provided at the end face of the spray seat 220. The cavity 223 provides space for the sliding of the locking rod 230 and accommodates the movable part of the locking ball 224. Locking grooves 213 are provided on the inner walls of the insertion hole 212. The locking grooves 213 can cooperate with the locking ball 224 to form a locking structure, restricting the relative movement of the insertion post 222 and the insertion hole 212. The end of the cavity 223 extends into the insertion post 222, and the cavity wall of the cavity 223... Several sleeve holes 2221 are provided, each corresponding to a position of the locking groove 213. These sleeve holes 2221 provide installation positions for the locking steel ball 224, and their positional correspondence with the locking groove 213 ensures effective locking. There are four sleeve holes 2221, distributed on the four side end faces of the insertion post 222. This distribution allows the locking steel ball 224 to lock from four directions, improving locking reliability. Locking devices are fitted inside the sleeve holes 2221. The steel ball 224, which is a locking ball, can roll within the sleeve hole 2221. It locks the insertion post 222 to the fixing seat 210 by embedding in the locking groove 213. The locking rod 230 has a sliding rod 231 at its head end. The sliding rod 231 extends into the cavity 223 and slides within it. The sliding of the sliding rod 231 moves the pushing part 233, thereby controlling the position of the locking steel ball 224. The sliding rod 231 also has an end rod 232 at its head end. 2. A tapered pushing part 233 is provided at the connection with the sliding rod 231. The tapered structure of the pushing part 233 can gradually squeeze the locking steel ball 224 when the sliding rod 231 moves, so that the locking steel ball 224 can smoothly enter and exit the locking groove 213. When the sliding rod 231 is pushed inward along the axis of the cavity 223, the pushing part 233 pushes the locking steel ball 224, so that the locking steel ball 224 extends from the outer end of the sleeve hole 2221 into the locking groove 213, thereby achieving the purpose of locking the plug-in post 222.

[0040] like Figure 4 Furthermore, the sleeve hole 2221 is connected to the cavity 223. This connection structure ensures that the pushing part 233 can contact the locking steel ball 224 and push it. The sleeve hole 2221 is a conical hole structure. The diameter of the sleeve hole 2221 gradually decreases in the direction of gradually moving away from the cavity 223. The conical structure can guide the movement direction of the locking steel ball 224. At the same time, it cooperates with the pushing part 233 to realize the extension and retraction of the locking steel ball 224. The minimum diameter of the sleeve hole 2221 is smaller than the diameter of the locking steel ball 224 to prevent the locking steel ball 224 from falling out of the sleeve hole 2221 and avoid the locking steel ball 224 falling off and causing the locking structure to fail.

[0041] Furthermore, the minimum distance between the inner wall of the pushing part 233 and the outer wall of the insertion post 222 is less than the diameter of the locking steel ball 224. When the sliding rod 231 moves inward along the cavity 223 until the sliding rod 231 partially covers the inner end of the sleeve hole 2221, the locking steel ball 224 is completely squeezed into the sleeve hole 2221 by the sliding rod 231. This dimensional relationship ensures that the pushing part 233 can effectively push the locking steel ball, so that the outer end of the locking steel ball 224 protrudes outward from the outer port of the sleeve hole 2221.

[0042] It is worth noting that the diameter of the locking rod 230 is smaller than that of the sliding rod 231. This dimensional difference provides space for the installation of the spring 234 and allows the sliding rod 231 to slide stably within the cavity 223. The locking rod 230 is fitted with a spring 234, whose elastic force pushes the sliding rod 231 to maintain an inward tendency, ensuring the stability of the locked state. A cover plate 235 is installed on the end face of the spray seat 220, which can close the end of the cavity 223 to prevent... Dust and other debris enter, while providing support for the spring 234. The locking rod 230 passes through the cover plate 235 and is slidably connected to the cover plate 235. This structure ensures that the locking rod 230 can slide stably while limiting its radial sway. The first end of the spring 234 abuts against the inner end of the cover plate 235, and the end of the spring 234 abuts against the end of the sliding rod 231. The spring 234 is in a compressed state. The compressed spring 234 can continuously apply a pushing force to the sliding rod 231, ensuring the reliability of the locking structure.

[0043] It is worth noting that the diameter of the end rod 232 is smaller than that of the sliding rod 231. This size design provides space for the retraction of the locking ball 224, facilitating the unlocking operation. The radius difference between the end rod 232 and the sliding rod 231 is smaller than the diameter of the locking ball 224, preventing the locking ball 224 from rolling out from the inner end of the sleeve hole 2221 and avoiding the locking ball 224 from falling off from the inside, thus ensuring structural integrity. The pushing part 233 is smoothly connected between the sliding rod 231 and the end rod 232. The smooth connection structure can reduce the friction between the pushing part 233 and the locking ball 224, making the operation more effortless. When the sliding rod 231 is pushed outward along the axial direction of the cavity 223 so that the position of the inner end of the sleeve hole 2221 is aligned with the end rod 232, the locking ball 224 can retract into the sleeve hole 2221. At this time, the insertion post 222 and the boss 211 are in the unlocked state.

[0044] like Figure 2 and Figure 5 As shown, in addition, a lever 236 is bolted to the end of the locking lever 230. The bolt installation method facilitates the disassembly and replacement of the lever 236. The diameter of the lever 236 is larger than the diameter of the locking lever 230. The larger diameter makes it easier for the operator to move the locking lever 230, improving the ease of operation. The lever 236 is used to move the locking lever 230.

[0045] In this embodiment, the carving water-cooling device for preventing wood cracking is used as follows: First, the lever 236 is moved outward, causing the locking rod 230 and sliding rod 231 to move outward, aligning the end rod 232 with the inner end of the sleeve hole 2221. The locking steel ball 224 retracts into the sleeve hole 2221, and the insertion post 222 of the spray seat 220 is inserted into the insertion hole 212 of the fixing seat 210. Then, the lever 236 is released, the spring 234 pushes the sliding rod 231 inward, and the pushing part 233 presses the locking steel ball 224. Bead 224 is inserted to make the locking steel ball 224 extend out of the sleeve hole 2221 and embed into the locking groove 213, thus completing the installation and fixing of the spray mechanism 200; next, the pipe connector 225 is connected to the external water source, and the bamboo joint tube 226 is bent so that its water outlet is aligned with the carving area; finally, the carving equipment is started, and the water source enters the bamboo joint tube 226 through the pipe connector 225 and the water passage hole, spraying water to the carving area for cooling. If it is not needed, the lever 236 is turned again to unlock it, and the spray seat 220 can be removed from the fixed seat 210.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
