DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figure 1-Figure 5The EPS foam board punching device shown includes a first shell 1, a fixing plate 11 is fixedly installed on the lower surface of the first shell 1, a hollow connecting rod 7 is rotatably installed in the middle of the fixing plate 11, a drill bit 71 is detachably installed on the bottom end of the hollow connecting rod 7, the interior of the drill bit 71 is connected to the interior of the hollow connecting rod 7, a plurality of evenly distributed air permeable grooves 72 are provided on the outer surface of the hollow connecting rod 7, a motor is fixedly installed inside the first shell 1, a driving end of the motor is fixedly installed on the end of the hollow connecting rod 7, a plurality of annularly distributed spring telescopic rods 12 are fixedly installed between the fixing plate 11 and the upper surface of the second shell 2, and a plurality of evenly distributed pressing plates 23 are fixedly installed on the bottom end of the outer surface of the second shell 2.

[0027] In actual use, the first shell 1 is connected to an external electric push rod or other device for lifting. This is the prior art and is not within the protection scope of the present utility model, so it will not be elaborated here. When the lifting device drives the device close to the foam board, the pressing plate 23 presses the foam board. At the same time, the motor drives the hollow connecting rod 7 and the drill bit 71 to rotate at high speed. When it continues to descend, the drill bit 71 escapes from the inside of the second shell 2. At this time, the spring telescopic rod 12 is compressed, and at the same time, the drill bit 71 punches holes in the foam board. During this process, the second shell 2 does not rotate. The pressing plate 23 can increase the friction between the second shell 2 and the foam board, so that the second shell 2 can be stable and still on the surface of the foam board. When the drilling is completed, the device is controlled to rise. At this time, the spring telescopic rod 12 can push the second shell 2 to move and store the drill bit 71 into the inside of the second shell 2, which is convenient for the next use.

[0028] A second shell 2 is provided below the fixed plate 11, and a first rotating ring 3 is rotatably installed in the middle of the upper surface of the second shell 2, a hollow connecting rod 7 is slidably clamped in the middle of the first rotating ring 3, and a fan blade 6 is rotatably clamped on the upper end of the inner part of the first rotating ring 3. A conical mesh plate 5 is fixedly installed on the inner upper surface of the second shell 2, and a plurality of evenly distributed discharge grooves 24 are provided at the upper end of the second shell 2. A second rotating ring 4 for connecting the interior of the second shell 2 and the interior of the hollow connecting rod 7 is provided on the lower surface of the first rotating ring 3, and a plurality of evenly distributed ventilation grooves 22 are provided at the bottom end of the second shell 2. A collecting shell 21 is fixedly sleeved on the upper end of the second shell 2, and the discharge groove 24 is located inside the collecting shell 21. A collecting pipe 211 is connected and installed on one side of the collecting shell 21.

[0029] When the motor drives the hollow connecting rod 7 and the drill bit 71 to rotate, the hollow connecting rod 7 will drive the fan blades 6 to rotate inside the second shell 2, and then the rotation of the fan blades 6 drives the second shell 2 to form an airflow, and the airflow is transported from the bottom of the fan blades 6 to the top of the fan blades 6. Because the drill bit 71 will produce a large amount of foam slag flying when cutting the foam board, which not only affects the processing, but also may cause the workers to inhale it into the lungs and cause injuries, so when the device is working, a relatively sealed chamber is formed inside the second shell 2. At this time, the drill bit 71 works inside the second shell 2, and the airflow enters the second shell 2 from the outside of the second shell 2 through the ventilation slots 22 and is transported upward to the fan. Above the blade 6, because the weight of the foam residue is relatively light, it will be carried by the airflow and pass through the fan blade 6. Because the shape of the conical mesh plate 5 is a conical mesh plate, the foam residue will be blocked by the conical mesh plate 5, and the airflow will be divided into two streams by the conical mesh plate 5. The first stream of air passes through the discharge chute 24 and enters the interior of the collecting shell 21. When the first stream of air passes through the discharge chute 24, it will drive the foam residue blocked thereon into the interior of the collecting shell 21. After being collected inside the collecting shell 21, they will be discharged along the collecting pipe 211. The collecting pipe 211 can be connected to an external collecting device for waste recycling or direct treatment to prevent a large amount of residue from flying in the air and causing injuries to workers.

[0030] The second rotating ring 4 includes a first rotating ring 41, and the second rotating ring 42 is rotated inside the first rotating ring 41. The second rotating ring 42 is provided with a plurality of second through grooves 421 corresponding to the air-permeable grooves 72, and the first rotating ring 41 is provided with a plurality of first through grooves 411 corresponding to the second through grooves 421. The first rotating ring 41 is fixedly clamped in the middle part of the conical mesh plate 5, and the first sleeve 31 is fixedly installed on the upper surface of the first rotating ring 3, and the first sleeve 31 is slidably sleeved on the outer surface of the hollow connecting rod 7, and the second sleeve 61 is fixedly installed on the upper surface of the fan blade 6, and the third sleeve 62 is fixedly installed on the lower surface of the fan blade 6, and the top end of the second sleeve 61 is fixedly installed on the bottom end of the second rotating ring 42, and the fan blade 6, the second sleeve 61, and the third sleeve 62 are all slidably sleeved on the outer surface of the hollow connecting rod 7.

[0031] When the drill bit 71 is working, the cut waste will be stuck in the inside of the hollow connecting rod 7 and the drill bit 71. If it is not cleaned, it will affect the next processing. Therefore, the second airflow divided by the conical mesh plate 5 will pass through the first through groove 411 and the second through groove 421 and enter the inside of the hollow connecting rod 7 through the air-permeable groove 72. At this time, the inside of the hollow connecting rod 7 forms a slight positive pressure due to the entry of the airflow, and then when the punching is completed, the air pressure will directly flush the waste out of the inside of the hollow connecting rod 7 and the drill bit 71 to prevent waste blockage. Using one fan blade 6 can simultaneously achieve the cleaning of slag and the removal of waste.

[0032] It should be noted that, because the hollow connecting rod 7 moves up and down during work, the air groove 72 may be exposed to the outside, resulting in the inability to form a micro-positive pressure inside the hollow connecting rod 7. Therefore, by setting the drill bit 71, the second sleeve 61, and the third sleeve 62, when the hollow connecting rod 7 moves, the other positions of the air groove 72 will be in a sealed state, and the first rotating ring 3 and the fan blade 6 will be more stable when rotating. When the hollow connecting rod 7 rotates, it will drive the second rotating ring 42 to rotate, and then the first through groove 411 and the second through groove 421 will be continuously opened and closed, so the airflow entering the collection shell 21 will increase from time to time, making it easier to drive the residue into the collection shell 21 to be collected.

[0033] Working principle: In actual use, the first shell 1 is connected to an external electric push rod or other device for lifting. When the lifting device drives the device close to the foam board, the pressing plate 23 presses the foam board. At the same time, the motor drives the hollow connecting rod 7 and the drill bit 71 to rotate at high speed. When it continues to descend, the drill bit 71 escapes from the inside of the second shell 2. At this time, the spring telescopic rod 12 is compressed, and at the same time, the drill bit 71 punches holes in the foam board. During this process, the second shell 2 does not rotate. The pressing plate 23 can increase the friction between the second shell 2 and the foam board, so that the second shell 2 can be stable and still on the surface of the foam board. When the drilling is completed, the device is controlled to rise. At this time, the spring telescopic rod 12 can push the second shell 2 to move and store the drill bit 71 into the inside of the second shell 2, which is convenient for the next use.

[0034] When the motor drives the hollow connecting rod 7 and the drill bit 71 to rotate, the hollow connecting rod 7 will drive the fan blades 6 to rotate inside the second shell 2, and then the rotation of the fan blades 6 drives the airflow to be formed inside the second shell 2, and the airflow is transported from the bottom of the fan blades 6 to the top of the fan blades 6. Because the drill bit 71 will generate a large amount of foam slag flying when cutting the foam board, which not only affects the processing, but also may cause the workers to inhale it into the lungs and cause injuries, so when the device is working, a relatively sealed chamber is formed inside the second shell 2. At this time, the drill bit 71 works inside the second shell 2, and the airflow will enter from the outside of the second shell 2 through the ventilation slots 22. The foam residue is then transported to the top of the fan blade 6 because of its light weight. The foam residue will be entrained by the airflow and pass through the fan blade 6 because of its light weight. The foam residue will be blocked by the conical mesh plate 5 because of its conical shape. The airflow will be divided into two streams by the conical mesh plate 5. The first stream of air passes through the discharge chute 24 and enters the interior of the collecting shell 21. When the first stream of air passes through the discharge chute 24, it will drive the foam residue blocked thereon to enter the interior of the collecting shell 21. After being collected in the interior of the collecting shell 21, they will be discharged along the collecting pipe 211. The collecting pipe 211 can be connected to an external collecting device.

[0035] When the drill bit 71 is working, the cut waste will be stuck in the inside of the hollow connecting rod 7 and the drill bit 71. If it is not cleaned, it will affect the next processing. Therefore, the second airflow divided by the conical mesh plate 5 will pass through the first through groove 411 and the second through groove 421 and enter the inside of the hollow connecting rod 7 through the air-permeable groove 72. At this time, the inside of the hollow connecting rod 7 forms a slight positive pressure due to the entry of the airflow, and then when the punching is completed, the air pressure will directly flush the waste out of the inside of the hollow connecting rod 7 and the drill bit 71 to prevent blockage.

[0036] It should be noted that, because the hollow connecting rod 7 moves up and down during work, the air groove 72 may be exposed to the outside, resulting in the inability to form a micro-positive pressure inside the hollow connecting rod 7. Therefore, by setting the drill bit 71, the second sleeve 61, and the third sleeve 62, when the hollow connecting rod 7 moves, the other positions of the air groove 72 will be in a sealed state, and the first rotating ring 3 and the fan blade 6 will be more stable when rotating. When the hollow connecting rod 7 rotates, it will drive the second rotating ring 42 to rotate, and then the first through groove 411 and the second through groove 421 will be continuously opened and closed, so the airflow entering the collection shell 21 will increase from time to time, making it easier to drive the residue into the collection shell 21 to be collected.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
