TECHNICAL FIELD

[0001] The present application relates to the technical field of wind valve processing, in particular to a transfer mechanism for fan wind valve processing. BACKGROUND

[0002] Fan wind valves are core control elements in ventilation and air conditioning systems, mainly used for adjusting air flow, blocking fire and ensuring safe operation of the system. According to structural characteristics, they can be divided into: louver: multi-blade frame structure, opening and closing mode including airflow drive, synchronous mechanism (internal / external connecting rod); butterfly valve: single-piece circular or double-piece butterfly valve plate, 90° rotation control on-off, suitable for high temperature and high pressure environment; double-leaf multi-blade valve: sealed rubber strip edge, low air leakage rate, mainly used for air duct branches.

[0003] At present, the multi-blade frame structure of the fan wind valve is the most widely used, and its outer shell is usually a square structure formed by a continuous metal sheet through stamping and bending.

Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0035] The present application will be further described below with reference to the embodiments.

[0036] Embodiment: Refer to Figures 1-10The utility model provides a kind of transfer mechanism for fan valve processing, including first conveyor 1, bending machine 2 and second conveyor 4, bending machine 2 is located between first conveyor 1 and second conveyor 4, bending machine 2 has a horizontal compression beam 201, compression beam 201 can be lifted, when bending to the outer shell 3 of fan valve, compression beam 201 is pressed down, subsequently lower bending plate rotates upwards, and originally straight metal sheet is bent 90 ° upwards, and preliminary form of the outer shell 3 of fan valve is formed after bending three times continuously.In the outer shell 3 is bent after completion, when outer shell 3 just completely covers compression beam 201, to want to take down outer shell 3, then must make the opening of the head-to-tail connection of outer shell 3 larger, so that it can pass through compression beam 201, currently basically by artificial pulling the upper half of outer shell 3 upwards, using the elasticity of metal sheet to make the opening of outer shell 3 open, then can take out outer shell 3.To this end, the utility model is equipped with fixed hoisting suspension plate 5 above second conveyor 4, and pulling mechanism is installed on the lower surface of suspension plate 5 to realize the automatic transfer of outer shell 3.

[0037] Specifically, pulling mechanism includes fixedly installed air cylinder 6 on the lower surface of suspension plate 5, and the driving shaft of air cylinder 6 is vertically installed with horizontally arranged sleeve 8, both ends of sleeve 8 are movably installed with L-shaped rod 7, and the end of L-shaped rod 7 away from sleeve 8 is respectively connected with upper rod 701 and lower rod 702, and the end of upper rod 701 is installed with lifting cover assembly 703, and the end of lower rod 702 is installed with pulling and pressing assembly 704.

[0038] The upper end of two L-shaped rods 7 is equipped with lug 9, and the lower surface of suspension plate 5 is respectively provided with guide groove 10 matched with two lugs 9, so that two L-shaped rods 7 are close to each other when moving forward to the end, and far away from each other when moving backward to the end.

[0039] When the outer shell 3 is bent after completion, the outer shell 3 is continuously pushed forward by a section of pushing equipment of bending process to expose the front end of outer shell 3, then air cylinder 6 is started, sleeve 8 drives two L-shaped rods 7 to move to outer shell 3, when L-shaped rod 7 moves forward to the end (lug 9 reaches the front end of guide groove 10), two L-shaped rods 7 are automatically close to each other, so that lifting cover assembly 703 and pulling and pressing assembly 704 enter the inner side of outer shell 3, then lifting cover assembly 703 and pulling and pressing assembly 704 start working, and air cylinder 6 pulls L-shaped rod 7 backward, lifting cover assembly 703 lifts the upper half of outer shell 3, and the head-to-tail connection of outer shell 3 is opened, so that outer shell 3 can pass through compression beam 201, and outer shell 3 is smoothly pulled to second conveyor 4 and is transferred to next station by second conveyor 4.When L-shaped rod 7 moves backward to the end (lug 9 reaches the rear end of guide groove 10), two L-shaped rods 7 are automatically far away from each other, so that lifting cover assembly 703 and pulling and pressing assembly 704 move out from the inside of outer shell 3, and do not hinder the transfer of outer shell 3 to the rear.

[0040] ReferFigures 4-6 The lifting cover assembly 703 comprises a motor 7031 fixedly installed on the inner side of the upper rod 701 away from the L-shaped rod 7 and a cam 7032 installed on the output shaft of the motor 7031. When the motor 7031 is in standby, the cam 7032 is in a horizontal state, and when the motor 7031 works, the cam 7032 rotates upward by 90° and then resets. After the motor 7031 is turned on, the cam 7032 slowly rotates upward by 90°, and the cam 7032 gradually lifts the upper half of the outer shell 3, so that the opening of the outer shell 3 becomes larger, and thus the outer shell 3 can be moved out through the compression beam 201. In order to ensure the stability of the lifting cover assembly 703 during work, the motor 7031 can be selected as a low-speed motor, and the rotating speed is controlled within a reasonable range to avoid excessive impact on the outer shell 3, so that the outer shell 3 can be opened at a suitable speed.

[0041] Referring to Figures 7-8 The pull-and-press assembly 704 comprises a connecting block 7041 fixedly installed on the inner side of the lower rod 702 away from the L-shaped rod 7, a movable plate 7042 horizontally inserted on the outer wall of the connecting block 7041 toward the side of the L-shaped rod 7, a top plate 7043 installed on the end of the movable plate 7042, and a spring connected between the top plate 7043 and the connecting block 7041. After the pull-and-press assembly 704 enters the inner side of the outer shell 3, the top plate 7043 starts to contact the inner wall of the outer shell 3 under the pulling of the air cylinder 6, and drives the outer shell 3 to move onto the second conveying belt 4. The outer wall of the connecting block 7041 toward the side of the top plate 7043 is further provided with a touch button 7044, which triggers the motor 7031 when triggered. Since the top plate 7043 is elastically installed, and the outer shell 3 has a certain friction with the first conveying belt 1 and the bending machine 2, when the outer shell 3 makes the spring on the top plate 7043 contract to a certain extent, the touch button 7044 is triggered, at which time the lifting cover assembly 703 is opened, and the outer shell 3 is opened while being pulled, and when the opening reaches the position of the compression beam 201, the opening is opened to a size that can pass through the compression beam 201.

[0042] Further, the bottom wall of the connecting block 7041 is provided with a movable slot 7046, and a wedge-shaped block 7047 is elastically inserted into the movable slot 7046. The bottom end of the wedge-shaped block 7047 is provided with a pressing plate 7045, and the movable plate 7042 extends into the movable slot 7046 and cooperates with the wedge-shaped block 7047. When the spring is compressed, the movable plate 7042 enters the movable slot 7046, the end of the movable plate 7042 abuts against the wedge-shaped block 7047 to make the wedge-shaped block 7047 move downward, and the pressing plate 7045 extends downward to abut against the inner bottom wall of the outer shell 3. This design can avoid that the outer shell 3 is lifted upward as a whole by the lifting cover assembly 703, so that the outer shell 3 can be stably opened, and the stability of the outer shell 3 during moving and conveying is improved, and the use effect is improved.

[0043] Referring toFigure 5 The L-shaped rod 7 is movably inserted into the end of the sleeve 8 away from the end of the upper rod 701, and a pull spring connected with the L-shaped rod 7 is installed in the inside of the sleeve 8, for applying a pulling force to the L-shaped rod 7, so that the L-shaped rod 7 has the characteristic of automatic reset inward.

[0044] Referring to Figures 9-10 The guide groove 10 is a right-angled trapezoidal structure, and the guide groove 10 includes an outer groove 1001, an inner groove 1002, an inclined groove 1003, and a stay groove 1004, the outer groove 1001 and the stay groove 1004 are flush, and the angle between the inclined groove 1003 and the inner groove 1002 is not less than 135°.

[0045] Based on the above design, when the air cylinder 6 is in standby, the convex rod 9 is located in the stay groove 1004, when the air cylinder 6 pushes the L-shaped rod 7 to move forward, when the convex rod 9 moves to the end of the outer groove 1001, the L-shaped rod 7 and the convex rod 9 are automatically reset into the inner groove 1002 under the pulling force of the pull spring, at this time, the two L-shaped rods 7 are close to each other, the cover lifting assembly 703 and the tensioning and pressing assembly 704 enter the inside of the outer shell 3, when the air cylinder 6 pulls the L-shaped rod 7 backward, when the convex rod 9 moves to the end of the inner groove 1002, it enters the stay groove 1004 through the inclined groove 1003, at this time, the air cylinder 6 stops and enters the standby state, during this process, the two L-shaped rods 7 are forced to move away again, and the cover lifting assembly 703 and the tensioning and pressing assembly 704 also move out of the inside of the outer shell 3, at this time, the outer shell 3 completely falls onto the second conveying belt 4, and is continuously conveyed to the next station by the second conveying belt 4.

[0046] Because the pull spring makes the two L-shaped rods 7 have the tendency to automatically approach each other, in order to avoid the convex rod 9 from falling into the inner groove 1002 from the inclined groove 1003 in the next operation, a one-way flap 1005 is hinged at the connection between the outer groove 1001 and the inclined groove 1003, the one-way flap 1005 can only open to one side of the outer groove 1001, and will not be hindered when the convex rod 9 moves from the inner groove 1002 to the stay groove 1004, and the one-way flap 1005 automatically resets after the convex rod 9 enters the stay groove 1004, thereby hindering the convex rod 9 from entering the inclined groove 1003 from there, this design makes the equipment more stable during operation, and reduces the probability of failure.

[0047] It should be noted that the one-way flap 1005 is hinged on the inner wall of the inner side of the guide groove 10, which can increase the movement range of the one-way flap 1005, so that the one-way flap 1005 is designed to be longer, and the place can be maximally closed to avoid the convex rod 9 from entering.

[0048] Working principle: after the bending is completed, the shell body 3 is continuously pushed forward by a certain distance (which can be achieved by setting the existing equipment and procedures, and the present application will not be described in detail) with the help of the pushing device at the bending process, so that the front end of the shell body 3 is exposed, facilitating the lifting cover assembly 703 and the pulling and pressing assembly 704 to enter, and then the cylinder 6 starts to push the lifting cover assembly 703 and the pulling and pressing assembly 704 forward (the pushing of the cylinder 6 and the forward pushing of the bending process can be carried out at the same time, which can be set according to the actual situation), when the protruding rod 9 reaches the front end of the outer groove 1001, it is automatically entered into the inner groove 1002 under the action of the tension spring, and the two L-shaped rods 7 are automatically close, so that the lifting cover assembly 703 and the pulling and pressing assembly 704 enter the inside of the shell body 3. At this time, the cylinder 6 starts to pull the L-shaped rod 7 backward, and the top plate 7043 starts to contact the inner wall of the shell body 3. Because the shell body 3 has a certain friction with the first conveying belt 1 and the bending machine 2, the shell body 3 will exert a certain resistance on the top plate 7043, when the shell body 3 forces the spring on the top plate 7043 to shrink to a certain extent, the touch button 7044 triggers, at this time, the lifting cover assembly 703 is opened, pulling the shell body 3 at the same time makes the shell body 3 open. In this process, the movable plate 7042 enters the movable groove 7046, the end of the movable plate 7042 is on the wedge block 7047 to make the wedge block 7047 move down, and the pressing plate 7045 extends downward to top the inner bottom wall of the shell body 3, preventing the shell body 3 from being lifted upward by the lifting cover assembly 703 as a whole, and also ensuring that the upper half of the shell body 3 is stably opened. When the opening reaches the position of the pressing beam 201, the opening degree of the shell body 3 is sufficient to pass through the pressing beam 201 (this purpose can be achieved by setting the position of the lifting cover assembly 703 and the size of the cam 7032), and the shell body 3 is smoothly pulled onto the second conveying belt 4 and is moved backward to the next station by the second conveying belt 4. When the shell body 3 falls onto the second conveying belt 4, the shell body 3 will move with the second conveying belt 4, at this time, the top plate 7043 is separated from the shell body 3, the touch button 7044 is released, the cam 7032 is reset, the opening of the shell body 3 is closed, and the shell body 3 is moved to the next station in a stable state. When the protruding rod 9 enters the resting groove 1004 through the inclined groove 1003, the two L-shaped rods 7 are forced to move away, so that the lifting cover assembly 703 and the pulling and pressing assembly 704 move out of the shell body 3, which will not hinder the shell body 3 from moving backward.

[0049] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit it; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present application.
