Description

Technical Field

[0001] The invention relates to the technical field of drilling devices for bamboo and wooden blinds blades, in particular to a drilling device for bamboo and wooden blinds blades. Background Art

[0002] Venetian blinds are a style of windows that originated in China. In ancient Chinese architecture, there were straight lattice windows, which were used in all dynasties from the Warring States Period to the Han Dynasty. The vertical bars are called straight lattice windows, and the horizontal bars are called horizontal lattice windows. Horizontal lattice windows are an original style of Venetian blinds, or it can be said that it is the original state of Venetian blinds.

[0003] The composition of the shutter blades is varied, among which bamboo and wood shutters are very popular. In the production and processing of bamboo and wood shutter blades, the raw materials need to be trimmed into blades of suitable size, and then a drilling machine is used to drill holes of suitable size on the blades. The blade material is bamboo and wood, so the blade strength is low. When the drill is drilling holes in the blades, a large amount of fine granular wood chips will be generated due to the friction between the drill and the blades. The wood chips are small in size and light in weight, and are easily dispersed to the outside with the flow of external air. Therefore, an air suction mechanism is generally provided around the drilling device of the bamboo and wood shutter blade drill to remove the granular wood chips generated when drilling holes in the bamboo and wood blades. Generally, the wood chips are carried by airflow and introduced into the storage device. The filter is placed in the center, and the wood chips are filtered out of the airflow through the filter plate and stored in the storage device. Since the wood chips are small in size and light in weight, the wood chips are still easy to move with the airflow in the storage device. When the airflow passes through the holes of the filter plate, the wood chip particles are easily blocked in the holes of the filter plate due to the push of the airflow, resulting in the blockage of the filter plate holes, so that the air path is cut off, resulting in a decrease or disappearance of the air flow, and the device cannot be used normally, so that a certain amount of wood chips are always gathered around the drill bit. At the same time, due to the friction of the drill bit, the temperature of the drill bit continues to rise, and the wood chips are small in size and easy to burn. They are easily ignited by high temperature and emit a large amount of heat, which damages the surface of the blades. It cannot well meet the drilling device for a long time to perform drilling operations on the blades of bamboo and wooden blinds. Summary of the invention

[0004] The object of the present invention is to provide a drilling device for bamboo and wooden blinds blades to solve the problems raised by the above-mentioned background technology.

[0009] Preferably, the inner bottom wall of the storage cylinder is hemispherical, and a net cylinder is fixedly installed at the center position inside the storage cylinder.

[0010] By adopting the above technical solution, the hemispherical inner wall of the storage cylinder allows water entering the storage cylinder to move toward the net cylinder along the inner wall of the storage cylinder, which facilitates the water pipe to absorb the water in the storage cylinder.

[0011] Preferably, the cooling component includes a sleeve, which is sleeved on the outer peripheral side of the drill bit of the drill, and the inner wall of the sleeve is gap-matched with the drill bit of the drill. The outer peripheral side of the fixed sleeve is fixedly sleeved with an annular tube, and the interior of the annular tube is connected with the interior of the sleeve through a number of inclined support tubes.

[0012] By adopting the above technical solution, the ring and the support tube cooperate with each other to inject high-humidity gas into the sleeve downward from all directions, and at the same time the support tube supports and limits the position of the sleeve in the fixed tube. Due to the constraint of the fixed tube, the high-humidity gas is wrapped on the outer peripheral side of the drill bit of the drill, preventing the high-humidity gas from being unable to contact the drill bit of the drill due to the rotation of the drill bit.

[0013] Preferably, an exhaust pipe in a ring shape is fixedly mounted on the inner wall of the opening of the cover, the interior of the exhaust pipe is connected with the interior of the sleeve through a plurality of soft tubes, and a plurality of exhaust holes are formed at the bottom end of the exhaust pipe.

[0014] By adopting the above technical solution, the gas in the sleeve is discharged from the inner wall of the cover opening through the constraint of the exhaust pipe and the sleeve, and the adsorption of moisture in the air by the wood chips increases the adsorption force between the air and the particle wood chips, preventing the gas discharged from the sleeve from affecting the entrainment of the particle wood chips by the airflow.

[0018] By adopting the above technical solution, the airflow in the limiting cylinder entering the soft exhaust pipe is accelerated through the expansion of the hemispherical top cover, thereby increasing the pushing force of the airflow on the first impeller, thereby increasing the rotation speed of the first impeller.

[0020] By adopting the above technical solution, the wood chips in the air flow are intercepted in the water by the mesh sleeve, and the spirally arranged elastic tube allows the soft exhaust pipe and the soft air pipe to be extended and retracted in the length direction. The elastic tube constrains the soft exhaust pipe and the soft air pipe to always be located at a specific position on the outer peripheral side of the guide rail, and the soft exhaust pipe and the soft air pipe are constrained and protected, which facilitates the position adjustment of the drill.

[0021] Preferably, the humidification component includes an atomizing nozzle arranged in a ring shape, the atomizing nozzle is located in a limiting cylinder and is fixedly connected to the inner wall of the limiting cylinder through a connecting rod, the limiting cylinder is located above a plurality of mesh sleeves, a water pipe is fixedly penetrated at the center position of the mesh cylinder, the top end of the water pipe extends outside the storage cylinder and is connected to the inside of the water inlet of the atomizing nozzle through a water pump.

[0022] By adopting the above technical solution, the water returning into the limiting cylinder is broken up into small water droplets through the atomizing nozzle. When the air flow passes through the atomized water droplets, a small part of the water droplets are entrained and move along with the air flow, thereby further increasing the humidity of the air flow.

[0023] Preferably, a water absorption plate is provided between the limiting cylinder and the mesh sleeve, and the water absorption plate is fixedly connected to the inner wall of the limiting cylinder, and the water absorption plate is densely covered with honeycomb-shaped holes.

[0024] By adopting the above technical solution, the contact area between the airflow and the water in the water absorption plate is increased through the honeycomb holes, thereby increasing the evaporation rate of the water in the water absorption plate and preliminarily increasing the humidity of the exhaust gas.

[0025] Preferably, a rotating shaft is provided at the center of the water absorption plate and in the atomizing nozzle through a bearing, the top end of the rotating shaft extends into the soft air pipe and is fixedly provided with a first impeller, and the bottom end of the rotating shaft passes through a plurality of mesh sleeves and is inserted into the liquid guide tube, and the bottom end of the rotating shaft is fixedly provided with a second impeller.

[0026] By adopting the above technical solution, through the cooperation between the first impeller, the rotating shaft and the second impeller, the airflow pushes the water in the fixed cylinder to flow into the storage cylinder during the discharge process, thereby reducing the energy loss of the device.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: when the improved drilling equipment is drilling holes for bamboo and wooden venetian blinds, the cooling component, the interception component and the humidification component cooperate with each other to form gas circulation and liquid circulation, and the airflow will replace the fine particles of wood chips produced by drilling into the water during the flow process, and the wood chips are filtered out and stored in the storage cylinder through the interception component, and the airflow is humidified by the humidification component to increase the adhesion of the airflow to the wood chips, and the drill bit is cooled during the gas flow.

The water in the storage cylinder will flow back into the interception component through the humidification component for water reuse. At the same time, the airflow will be humidified and cooled. The humidified airflow will flow in a directional manner due to the constraint of the cooling component. The airflow after cooling will be The contact flow occurs on the outside of the drill bit, and the small water droplets in the air flow evaporate after contacting the drill bit, taking away the heat on the drill bit and continuously cooling the drill bit. The humidified air flow discharged at the opening of the cover re-enters the gas circulation. Due to the absorption of moisture in the air flow by the sawdust, a certain adhesion will be generated between the humidified air flow and the sawdust, making it easier for the air flow to carry the sawdust and move along with the air flow.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1 , Figure 2 and Figure 6The present invention provides a technical solution: a drilling device for bamboo and wood blinds, comprising a drilling device 1, which is mainly divided into three parts: a base 11, a guide rail 12 and a drill 13. A bamboo and wood blinds blade clamp is installed at a position corresponding to the drilling device on the top plate of the base 11; it also includes: a fixing cylinder 2, which is sleeved on the outer peripheral side of the drill bit of the drill 13, and the fixing cylinder 2 is fixedly connected to the outer shell of the drill 13 by bolts, and a cover 3 is slidably sleeved on the bottom of the drill 13; a storage cylinder 7, which is located at the top of the base 11, and the outer peripheral wall of the storage cylinder 7 is connected to the guide rail 12 and The top plate of the base 11 is in contact with each other, and a water injection interface is installed on the storage cylinder 7. When the device is in use, the water injection interface is connected to an external water injection device, and the water injection device regularly injects a suitable amount of water into the storage cylinder 7 through the water injection joint to stabilize the water content in the limit cylinder 51. The inner bottom wall of the storage cylinder 7 is hemispherical, and a mesh cylinder 10 is fixedly installed at the center position of the storage cylinder 7. The mesh cylinder 10 separates water and granular wood chips. A plurality of balls 8 are rotatably penetrated at the bottom end of the cover wall of the cover 3, and a spring 9 is provided between the annular tube 42 and the cover 3, and the two ends of the spring 9 are respectively fixedly connected to the annular tube 42 and the cover 3. The hemispherical inner wall of the storage cylinder 7 allows water entering the storage cylinder 7 to move along the inner wall of the storage cylinder 7 toward the mesh cylinder 10, and the friction between the cover 3 and the bamboo and wooden shutter blades is offset by the ball bearings 8. Since there is a small gap between the cover 3 and the bamboo and wooden shutter blades due to the support of the ball bearings 8, the setting of the spring 9 compresses the spring 9 when the cover 3 rises, and then the elastic force of the spring 9 pushes the cover 3 to return to its original position. The sliding of the cover 3 on the outside of the fixed cylinder 2 allows the cover 3 to be adjusted in position following the drilling operation of the drill 13.

[0038] according to Figure 1-2As shown, a cooling component 4 is provided in both the cover 3 and the fixed tube 2. The cooling component 4 includes a sleeve 41, which is sleeved on the outer peripheral side of the drill bit of the drill 13, and the inner wall of the sleeve 41 is in clearance with the drill bit of the drill 13. An annular tube 42 is fixedly sleeved on the outer peripheral side of the fixed tube 2, and the inside of the annular tube 42 is connected with the inside of the sleeve 41 through a plurality of inclined support tubes 43, and the support tube 43 penetrates the tube wall of the fixed tube 2 and the tube wall of the annular tube 42 and is fixedly connected with the tube wall of the fixed tube 2 and the tube wall of the annular tube 42. An exhaust pipe 44 in a ring shape is fixedly installed on the inner wall of the opening of the cover 3, and the inside of the exhaust pipe 44 is connected with the inside of the sleeve 41 through a plurality of soft tubes 45, and a plurality of exhaust holes 46 are opened at the bottom end of the exhaust pipe 44. Through the cooperation between the collar and the support tube 43, high-humidity gas is injected into the sleeve 41 from all directions and tilted downward. At the same time, the support tube 43 supports and limits the position of the sleeve 41 in the fixed tube 2, and the high-humidity gas is wrapped around the outer peripheral side of the drill bit of the drill 13 due to the constraint of the fixed tube 2. Through the constraint of the exhaust pipe 44 and the sleeve 41, the gas in the sleeve 41 is discharged from the inner wall of the opening of the cover 3, and the adsorption of air moisture by the wood chips increases the adsorption force between the air and the particle wood chips, preventing the gas discharged from the sleeve 41 from affecting the entrainment of the particle wood chips by the air flow. The deformation of the soft tube 45 allows the soft tube 45 to be deformed accordingly when the cover 3 slides.

[0039] according to Figure 1-6As shown, a retention assembly 5 is provided at a position corresponding to the storage cylinder 7 on the outer wall of the guide rail 12. The retention assembly 5 includes a limiting cylinder 51, which is fixedly installed at a position corresponding to the storage cylinder 7 on the outer wall of the guide rail 12. An exhaust gas pump 52 is installed on the outer peripheral wall of the limiting cylinder 51 through a one-way valve, and the interior of the exhaust gas pump 52 air inlet is connected to the interior of the fixed cylinder 2 through a soft exhaust gas pipe 53. The exhaust gas pump 52 is fixedly connected to the limiting cylinder 51. A hemispherical cover 54 is fixedly installed at the openings at both ends of the limiting cylinder 51. The fixed cylinder 2, the cover 54 and the storage cylinder 7 are all filled with a suitable amount of water. A liquid guide tube 55 is installed at the bottom center of the lower cover 54, and the liquid guide tube 55 is connected to the bottom center of the lower cover 54. One end of 55 away from the limiting cylinder 51 is connected to the storage cylinder 7 through a pipe connector. The pipe connector is divided into two parts, a joint and an interface, and the joint is threadedly connected to the interface. The interior of the upper cover 54 is connected to the interior of the ring tube 42 through a soft air pipe 56. A plurality of trumpet-shaped mesh sleeves 57 are fixedly installed in the limiting cylinder 51. The mesh sleeves 57 filter out the granular wood chips in the water and the granular wood chips in the air flow. The outer peripheral side of the soft air pipe 56 and the outer peripheral side of the soft exhaust pipe 53 are jointly fixedly sleeved with an elastic tube 58. The elastic tube 58 is threadedly wound and installed on the top of the guide rail 12. The elastic tube 58 is a plastic tube. By expanding the hemispherical top cover, the airflow in the limiting cylinder 51 entering the soft exhaust pipe 53 is accelerated, increasing the pushing force of the airflow on the first impeller 510, and the wood chips in the airflow are intercepted in the water by the mesh sleeve 57. The spirally arranged elastic tube 58 allows the soft exhaust pipe 53 and the soft air pipe 56 to be extended and retracted in the length direction, and through the constraint of the elastic tube 58, the soft exhaust pipe 53 and the soft air pipe 56 are always located at a specific position on the outer peripheral side of the guide rail 12, and the soft exhaust pipe 53 and the soft air pipe 56 are constrained and protected.

[0040] according to Figure 3-6As shown, a humidifying assembly 6 is provided between the intercepting assembly 5 and the storage cylinder 7. The humidifying assembly 6 includes an atomizing nozzle 61 arranged in a ring shape, the atomizing nozzle 61 is located in the limiting cylinder 51 and is fixedly connected to the inner wall of the limiting cylinder 51 through a connecting rod, the limiting cylinder 51 is located above a plurality of net sleeves 57, a water guide pipe 62 is fixedly penetrated at the center position in the net cylinder 10, the top end of the water guide pipe 62 extends to the outside of the storage cylinder 7 and is connected to the inside of the water inlet of the atomizing nozzle 61 through a water pump 63, the water pump 63 penetrates the cylinder wall of the fixed cylinder 2 and is fixedly connected to the fixed cylinder 2, the limiting cylinder 51 and the net sleeve 57, and the water absorption plate 64 is fixedly connected to the inner wall of the limiting cylinder 51, the water absorption plate 64 is a sponge plate, and the water absorption plate 64 is densely covered with honeycomb holes. The center position of the water absorption plate 64 and the atomizing nozzle 61 are penetrated by a rotating shaft 59 through a bearing. The top end of the rotating shaft 59 extends into the soft air pipe 56 and is fixedly installed with a first impeller 510, and the bottom end of the rotating shaft 59 passes through a plurality of mesh sleeves 57 and is inserted into the liquid guide tube 55, and the bottom end of the rotating shaft 59 is fixedly installed with a second impeller 512. The contact area between the airflow and the water in the water absorption plate 64 is increased through the honeycomb-shaped holes, thereby increasing the evaporation rate of the water in the water absorption plate 64, and preliminarily increasing the humidity of the exhaust gas. The water that flows back into the limiting cylinder 51 is broken up into small water droplets through the atomizing nozzle 61. When the airflow passes through the atomized water droplets, a small part of the water droplets are entrained and move along with the airflow, further increasing the humidity of the airflow. Through the mutual cooperation of the first impeller 510, the rotating shaft 59 and the second impeller 512, the airflow pushes the water in the fixed cylinder 2 to flow into the storage cylinder 7 during the discharge process.

[0041] Working principle: When drilling holes in the blades of bamboo and wooden blinds using the drilling device 1, firstly, the blades are fixed to a suitable position on the base 11 by a clamp, and then the injection pipe of the water injection device is connected to the water injection joint, and a suitable amount of water is injected into the storage cylinder 7 intermittently at a fixed time;

[0042] Then, the exhaust pump 52 and the water pump 63 are started. When the drill 13 is drilling holes in the blades of the bamboo and wooden blinds, a large amount of fine granular wood chips are generated at the drill bit due to the friction between the drill bit and the blades. At the same time, the temperature of the drill bit continues to rise due to the friction.

[0043] The water pump 63 absorbs the water in the storage cylinder 7 through the water pipe 62 and injects the water into the atomizing nozzle 61. The atomizing nozzle 61 breaks up the water injected into the limiting cylinder 51 into a large number of fine water droplets, so that a small part of the fine water droplets fill the top of the limiting cylinder 51 and the upper cover 54. In addition, most of the water droplets collide with each other to form larger water droplets, which move downward due to the weight of the water droplets and continue to fall on the water absorption plate 64 to be absorbed by the water absorption plate 64. Part of the water in the water absorption plate 64 falls from the bottom of the water absorption plate 64 into the water in the limiting cylinder 51, and the water refluxes.

[0044] At the same time, the exhaust pump 52 continuously sucks the gas in the fixed cylinder 2 into the water in the fixed cylinder 2 through the soft waste pipe, so that the fixed cylinder 2 is continuously in a negative pressure state, and the gas in the cover 3 is used to supplement it. The flowing air force will carry the granular wood chips into the limiting cylinder 51. After the airflow carrying the wood chips enters the water, since the density of the exhaust gas carrying the wood chips is less than the density of water, as the exhaust gas rises in the water, the wood chips in the exhaust gas come into contact with the water, so that the wood chips absorb enough water, increasing the weight of the wood chips, and when the wood chips absorb water, water and wood chips will produce The weight of the wood chips and the adsorption force of the water on the wood chips pull the wood chips out of the gas, and the mesh sleeve 57 intercepts the wood chips and stores them in the limiting cylinder 51. The gas that has cleaned the wood chips emerges from the water and flows upward. According to the above, when the airflow passes through the holes of the water absorption plate 64, another part of the water in the water absorption plate 64 evaporates into water vapor due to the flow of the gas and moves with the airflow due to the entrainment of the airflow, thereby preliminarily humidifying the airflow. According to the above, the gas after the preliminary humidification subsequently passes through the area densely covered with fine water droplets for further humidification of the airflow. The humidification process is performed in a step, and the gas is cooled simultaneously. After the humidification process, the airflow is accelerated through the upper cover 54 and enters the soft air pipe 56, and is introduced into the annular pipe 42 by the soft air pipe 56 to increase the pressure in the annular pipe 42. Due to the pressure difference between the inside of the annular pipe 42 and the inside of the sleeve 41, the humidified airflow flows obliquely downward from the support pipe 43 into the sleeve 41 to increase the air pressure in the sleeve 41. Due to the pressure difference between the inside of the sleeve 41 and the exhaust pipe 44, the gas in the sleeve 41 flows into the exhaust pipe 44 through the soft pipe 45. At the same time, due to the The humidified gas in the sleeve 41 moves from top to bottom along the drill bit, and the contact flow of the gas with a relatively low temperature cooperates with the evaporation of the fine water droplets in the gas after contacting the drill bit, quickly taking away the heat on the drill bit, and continuously cooling the drill bit. The gas entering the exhaust pipe 44 is discharged from the opening of the cover 3 through the exhaust hole 46, and cooperates with the gas flowing into the opening of the cover 3 from the outside to supplement the lost gas in the cover 3, forming a gas circulation, and then the granular wood chips generated at the drill bit are continuously brought into the water in the limiting cylinder 51 through the airflow;

[0045] When the airflow flows in the soft air pipe 56, the first impeller 510 drives the rotating shaft 59 to rotate rapidly, and simultaneously drives the second impeller 512 to move rapidly, so as to drive the liquid in the liquid guide tube 55 to flow into the liquid storage cylinder, thereby forming a negative pressure state in the liquid guide tube 55, and sucking water from the limiting cylinder 51 to replenish the water lost in the liquid guide tube 55. According to the above, the water flowing into the liquid storage cylinder is transported by the water pump 63 and flows back into the limiting cylinder 51, so that part of the water is refluxed, thereby forming a stable circulation. Water flow, when the water in the limiting cylinder 51 flows into the storage cylinder 7, the wood chips in the water flow into the storage cylinder 7 due to the water flow, and at the same time, the wood chips blocked in the holes of the mesh sleeve 57 due to the buoyancy of the wood chips in the water and the air flow are moved upward and gathered at the bottom of the storage cylinder 7, and the water mixed in the wood chips is filtered by the mesh cylinder 10, passes through the mesh cylinder 10 and gathers at the water inlet of the liquid guide tube 55 for water reflux, while the wood chips are filtered out by the mesh cylinder 10 and stored in the storage cylinder 7;

[0046] During the process of the wood chips being accumulated in the storage cylinder 7, due to the effect of gravity, the water in the wood chips and the water seeping out of the wood chips will still flow into the mesh cylinder 10 through the holes between the wood chips and the holes of the mesh cylinder 10;

[0047] When the wood chips in the storage cylinder 7 accumulate to a certain amount, the operation of the water pump 63 is stopped. After the pipe connector is disassembled, the storage cylinder 7 can be directly removed to clean the wood chips stored in the storage cylinder 7. After the wood chips in the storage cylinder 7 are cleaned, the storage cylinder 7 is put back to its original position, the pipe connector is reassembled, and then the water pump 63 is started for continued use.
