[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] 1. The present application sets an arc plate, and in the process of the mounting plate moving downward, the arc plate is driven to move downward and gradually contact with the steel bar, and then the steel bar drives the piston rod to move upward along the air cylinder through the arc plate, at which time the first spring is squeezed and has a tendency to recover, and then the piston rod drives the arc plate to clamp and fix the steel bar under the action of the elastic force of the first spring, thereby effectively preventing the steel bar from deviating during the cutting process, and then when the cutting is completed, the output end of the electric telescopic rod contracts and drives the mounting plate to move upward, and in the process of the mounting plate moving upward, the air cylinder moves upward, and at this time the first spring stretches and drives the piston rod to reset, and when the first spring resumes the freely stretched state, the piston rod drives the arc plate to disengage from the steel bar, that is, during the cutting process, there is no need for the user to manually fix or release the steel bar, which plays a role in the efficiency of steel bar discharging;
[0019] 2. The present application sets a straightening rod, and in the process of the steel bar moving along the groove, the straightening rod gradually contacts the inclined surface of the straightening rod, and applies a thrust to the inclined surface of the straightening rod, and then the straightening rod moves along the installation groove and squeezes the elastic pad. At this time, under the action of the elastic force of the elastic pad, the straightening rod drives the steel bar to move closer to the middle of the groove. At the same time, because the elastic pad has elastic force, the straightening rod can straighten steel bars of different sizes, that is, the user does not need to spend time straightening the steel bar before cutting, which plays a role in improving the efficiency of steel bar discharge;

Then, during the movement of the brush bristles, the debris on the surface of the filter is separated from the filter, thereby effectively preventing the filter from being blocked and affecting the normal flow of airflow through the filter to the air pump, thereby ensuring the normal passage of airflow through the filter.

DETAILED DESCRIPTION
[0030] 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.
[0031] See also Figures 1 to 5 , the utility model provides a technical solution:
[0032] A discharging device for a steel bar sawing machine comprises a workbench 1, a bracket 2 is fixedly mounted on the top wall of the workbench 1, an electric telescopic rod 3 is fixedly mounted on the bottom wall of the bracket 2, a mounting plate 22 is fixedly mounted on the output end of the electric telescopic rod 3, a motor 4 is fixedly mounted on the bottom wall of the mounting plate 22, a cutting disc 5 is fixedly mounted on the output end of the motor 4, a cutting groove matching the cutting disc 5 is provided on the bottom wall of the workbench 1, an air cylinder 6 is fixedly mounted on the bottom wall of the mounting plate 22, a fixing rod 7 is slidably mounted in the air cylinder 6, an arc plate 8 is fixedly mounted on the bottom wall of the fixing rod 7, and a first spring 9 is fixedly mounted between the top wall of the fixing rod 7 and the air cylinder 6.
[0033] When in use, the steel bar is placed on the top wall of the workbench 1, and then after the size is selected, the electric telescopic rod 3 and the motor 4 are started. At this time, the output end of the electric telescopic rod 3 drives the motor 4 to move downward through the mounting plate 22. During the downward movement of the motor 4, the cutting disc 5 is driven to gradually contact the steel bar and cut the steel bar, thereby achieving the purpose of cutting the steel bar. During the downward movement of the mounting plate 22, the arc plate 8 is driven to move downward and gradually contact the steel bar. Then, the steel bar drives the piston rod to move upward along the air cylinder 6 through the arc plate 8. At this time, the first spring 9 is squeezed and has a tendency to recover, and then in the first Under the action of the elastic force of the spring 9, the piston rod drives the arc plate 8 to clamp and fix the steel bar, thereby effectively preventing the steel bar from deviating during the cutting process. Then, when the cutting is completed, the output end of the electric telescopic rod 3 contracts and drives the mounting plate 22 to move upward. During the upward movement of the mounting plate 22, the air cylinder 6 moves upward. At this time, the first spring 9 extends and drives the piston rod to reset. When the first spring 9 resumes the freely extended state, the piston rod drives the arc plate 8 to break contact with the steel bar. That is, during the cutting process, there is no need for personnel to manually fix or release the steel bar, which improves the efficiency of steel bar discharging.
[0034] Specifically, Figure 1 , Figure 3 As shown, a groove is provided on the top wall of the workbench 1, and mounting grooves are symmetrically provided on the side walls of the groove. A straightening rod 10 is slidably installed in the mounting groove, and an elastic pad 11 is fixedly installed between the side wall of the straightening rod 10 and the mounting groove.
[0035] The elastic pad 11 is provided with a cavity, and an air inlet valve 12 communicating with the outside is inserted on the side wall of the cavity. An air exhaust valve 13 communicating with the mounting groove is also inserted on the side wall of the cavity.
[0036] By adopting the above technical solution, when in use, the steel bars can be placed in the groove through a conveyor and moved along the groove. In the process of the steel bars moving along the groove, they gradually contact the inclined surface of the straightening rod 10 and apply a thrust to the inclined surface of the straightening rod 10. Then the straightening rod 10 moves along the installation groove and squeezes the elastic pad 11. At this time, under the action of the elastic force of the elastic pad 11, the straightening rod 10 drives the steel bars to move closer to the middle of the groove. At the same time, since the elastic pad 11 has elastic force, the straightening rod 10 can straighten steel bars of different sizes, that is, there is no need for users to spend time straightening the steel bars before cutting, which improves the efficiency of steel bar discharge.
[0037] During the extension of the elastic pad 11, the cavity inhales air from the outside through the air inlet valve 12, and then during the compression of the elastic pad 11, the gas in the cavity flows into the installation groove through the exhaust valve 13, and flows to the outside through the gap between the straightening rod 10 and the installation groove. Since there will be debris in the process of cutting the steel bars, blowing air outward can prevent the debris from being stuck in the gap between the straightening rod 10 and the installation groove, thereby ensuring the normal movement of the straightening rod 10.
[0038] Specifically, Figure 1 , Figure 2 , Figure 4 As shown, a collecting box 14 is installed on the bottom wall of the workbench 1, and an air pump 15 whose input end is connected to the collecting box 14 is also fixedly installed on the bottom wall of the workbench 1, and a collecting hole connected to the collecting box 14 is opened on the groove.
[0039] A filter screen 16 that matches the input end of the air pump 15 is embedded on the side wall of the collection box 14 .
[0040] A brush plate 17 cooperating with the filter 16 is slidably mounted on the collection box 14, and bristles are evenly fixedly mounted on the side wall of the brush plate 17. A pneumatic telescopic rod 18 fixedly connected to the output end and the brush plate 17 is fixedly mounted on the side wall of the collection box 14, and an air pipe 19 connected to the air cylinder 6 is inserted at the input end of the pneumatic telescopic rod 18.
[0041] By adopting the above technical solution, the air pump 15 is started during the steel bar cutting process, and then the air pump 15 draws air through the collection box 14 and the collection hole. At this time, the debris generated during the cutting process flows into the collection box 14 along with the air flow, thereby effectively preventing the debris from floating in the air and posing a hidden danger to the health of users, thereby improving safety.
[0042] When debris accompanies the airflow through the collection box 14 and flows toward the air pump 15 , the filter 16 can be set to block the debris in the airflow, thereby effectively preventing the debris from entering the air pump 15 and causing damage to the air pump 15 , thereby extending the service life of the air pump 15 .
[0043] In the process of the piston rod moving upward along the air cylinder 6, the air flow in the air cylinder 6 is driven to flow into the pneumatic telescopic rod 18 through the air pipe 19, and then the output end of the pneumatic telescopic rod 18 is extended under the action of the air flow, and the bristles are driven to move downward through the brush plate 17, and then in the process of the movement of the bristles, the debris on the surface of the filter 16 is driven to break away from the contact with the filter 16, thereby effectively preventing the filter 16 from being blocked and affecting the normal flow of air through the filter 16 to the air pump 15, thereby ensuring the normal passage of air through the filter 16.
[0044] When the piston rod moves downward, the air cylinder 6 inhales air through the air pipe 19 and contracts the output end of the pneumatic telescopic rod 18. During the contraction of the output end of the pneumatic telescopic rod 18, the bristles are driven to reset, thus preparing for work again.
[0045] Specifically, Figure 1 As shown, the bottom wall of the collection box 14 is conical, and a plug plate 20 is detachably mounted on the bottom wall of the collection box 14 .
[0046] By adopting the above technical solution, when there are too many debris in the collection box 14 and it needs to be cleaned, the user can remove the plug plate 20, and then the debris in the collection box 14 flows to the outside under the action of gravity, which makes it easier to handle the debris.
[0047] Specifically, Figure 1 As shown, a scale line 21 is provided on the top wall of the workbench 1 .
[0048] By adopting the above technical solution, when a user cuts the steel bar, the user can judge the cutting length of the steel bar according to the scale line 21, and the user does not need to repeatedly measure the steel bar with a ruler, which plays a role in improving the efficiency of steel bar discharge.
[0049] Working principle: When in use, the steel bar is placed on the top wall of the workbench 1, and then after the size is selected, the electric telescopic rod 3 and the motor 4 are started. At this time, the output end of the electric telescopic rod 3 drives the motor 4 to move downward through the mounting plate 22. During the downward movement of the motor 4, the cutting disc 5 is driven to gradually contact the steel bar and cut the steel bar, thereby achieving the purpose of cutting the steel bar. During the downward movement of the mounting plate 22, the arc plate 8 is driven to move downward and gradually contact the steel bar. Then, the steel bar drives the piston rod to move upward along the air cylinder 6 through the arc plate 8. At this time, the first spring 9 is squeezed and has a tendency to recover. Then, under the action of the elastic force of the first spring 9, the piston rod drives the arc plate 8 to clamp and fix the steel bar, thereby effectively preventing the steel bar from deviating during the cutting process. Then, when the cutting is completed, the output end of the electric telescopic rod 3 contracts and drives the mounting plate 22 to move upward. During the upward movement of the mounting plate 22, the air cylinder 6 moves upward. At this time, the first spring 9 stretches and drives the piston rod to reset. When the first spring 9 resumes the free extension state, the piston rod drives the arc plate 8 to break contact with the steel bar; during the movement of the steel bar along the groove, it gradually contacts the inclined surface of the straightening rod 10. A thrust is applied to the inclined surface of the straightening rod 10, and then the straightening rod 10 moves along the installation groove and squeezes the elastic pad 11. At this time, under the action of the elastic force of the elastic pad 11, the straightening rod 10 drives the steel bar to move closer to the middle of the groove. At the same time, since the elastic pad 11 has elastic force, the straightening rod 10 can straighten steel bars of different sizes; during the extension of the elastic pad 11, the cavity inhales air from the outside through the intake valve 12, and then during the compression of the elastic pad 11, the gas in the cavity flows into the installation groove through the exhaust valve 13, and flows to the outside through the gap between the straightening rod 10 and the installation groove. Since there will be debris during the steel bar cutting process, blowing air outward can prevent the debris from getting stuck in the gap between the straightening rod 10 and the installation groove; in the process of the piston rod moving upward along the air cylinder 6, it drives the air flow in the air cylinder 6 to flow into the pneumatic telescopic rod 18 through the air pipe 19, and then under the action of the air flow, the output end of the pneumatic telescopic rod 18 extends, and drives the bristles to move downward through the brush plate 17, and then in the process of the movement of the bristles, the debris on the surface of the filter screen 16 is driven to break away from the filter screen 16, thereby effectively preventing the filter screen 16 from being blocked and affecting the normal airflow through the filter screen 16 to flow to the air pump 15.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
