Description

Technical Field

[0002] The vibrating screen of asphalt mixing equipment is usually composed of a screen core, a vibration system, and a vibrating screen shell. Specifically, the vibrating screen is driven by dual motors. During operation, the two vibrating motors rotate synchronously in opposite directions to make the eccentric block generate impact force. The impact force cancels each other out in the horizontal direction and is split into a resultant force in the direction perpendicular to the motor shaft. Therefore, the motion trajectory of the screen is a straight line. The two motor shafts have an inclination angle relative to the surface of the screen. Under the combined effect of the impact force and gravity, the material is thrown onto the screen and jumps forward in a straight line, thereby achieving the purpose of screening and grading. The vibrating screen core is mainly composed of large side plates on both sides, a screen core support for the screen, a screen, and a fixed mesh seat and a pulling mesh seat for tightening the screen. As the core component of the vibrating screen, the vibrating screen core is subjected to vibration loads for a long time, so the production requirements of the screen core are relatively high. Generally, the screen core support is a slender rod, such as a round tube, and its two ends need to be welded to the end plates. Due to the large number of vibrating screen core supports and high welding accuracy requirements, and the screen core supports are mostly slender rods, existing automatic welding equipment is not convenient for welding them, and the equipment investment cost is high and the welding efficiency is low.

DETAILED DESCRIPTION

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Please also read Figures 1 to 13 , now a vibration screen core support welding tool provided by the present invention is described. The vibration screen core support welding tool comprises a feeding device 1, a positioning welding device 2 and a finished product recovery device 3. The feeding device 1 has a storage area for placing the screen core support 4 to be welded, and the feeding device 1 has the freedom to move the screen core support 4 one by one toward one side thereof; the positioning welding device 2 is arranged on one side of the screen core support 4 of the feeding device 1 in the direction of moving, and the two end plates 5 to be welded in combination with the screen core support 4 are respectively connected to the positioning welding device 2, and the positioning welding device 2 is suitable for fixing the screen core support 4 and the two end plates 5, and the feeding device 1 is used for moving the screen core support 4 one by one to the positioning welding device 2; the finished product recovery device 3 is connected to the feeding device 1 and has a finished product area suitable for storing the welded screen core support 4, and the finished product recovery device 3 is suitable for receiving the welded screen core support 4 and guiding it to the finished product area.

[0020] The present invention provides a vibration screen core support welding tool. Compared with the prior art, the screen core support 4 can be moved in sequence by arranging a feeding device 1, a positioning welding device 2 and a finished product recovery device 3, thereby realizing the continuous operation of feeding, assembly welding and recovery of the screen core support 4, and facilitating the welding robot to perform combined welding on the screen core support 4 and two end plates 5. After welding, the two end plates 5 are respectively fixed at the two ends of the screen core support 4 to form a whole. The present invention solves the technical problems of inconvenient operation and low welding efficiency of the vibration screen screen core support 4 and the end plate 5. The present invention can realize automated operation, is conducive to welding, and has the technical effects of being able to meet the welding of the vibration screen core support 4, accurate welding positioning, simple structure, low cost and high production efficiency.

[0021] In some embodiments, see Figures 1 to 13The feeding device 1 includes a frame 11, a feeding track 12, an end baffle 13, a cylinder-driven adjustment baffle 14 and a feeding opening and closing device 15; the feeding track 12 is connected to the upper end of the frame 11, is arranged in an inclined shape, and the height of one end close to the positioning welding device 2 is lower than the height of the other end. The upper end of the feeding track 12 forms a storage area and is used to stack the screen core support 4. The screen core support 4 located in the storage area has a rolling freedom in the direction of the positioning welding device 2; the end baffle 13 is fixedly connected to one end of the frame 11, and the end baffle 13 is used to limit the screen core support located on the feeding track 12 One end of the support 4 moves along its axial direction; the cylinder-driven adjustment baffle 14 is connected to the other end of the frame 11, and has the freedom to move along the axial direction of the screen core support 4. The cylinder-driven adjustment baffle 14 is used to push the other end of the screen core support 4 located on the feeding track 12 to move along its axial direction, so that the screen core support 4 is restricted between the end baffle 13 and the cylinder-driven adjustment baffle 14; the feeding opening and closing device 15 is connected to the upper end of the frame 11 and is arranged near the positioning welding device 2, and is used to move the screen core support 4 near the positioning welding device 2 to the positioning welding device 2 one by one. In this embodiment, the frame 11 is a frame-type structure, and the feeding track 12 is two and spaced apart. The acute angle between its length direction and the width direction (horizontal plane) of the frame 11 is set, that is, the feeding track 12 is set in an inclined shape, and the screen core support 4 located at its upper end can roll in the direction close to the positioning welding device 2 by its own weight, and multiple screen core supports 4 are arranged side by side at the upper ends of the two feeding tracks 12. The screen core support 4 in this embodiment is a tubular component, such as a round tube, which is hollow inside. Two adjacent screen core supports 4 are in contact or abutment with each other. When a sand core support close to the positioning welding device 2 moves onto the positioning welding device 2, the multiple screen core supports 4 can automatically roll to the side close to the positioning welding device 2 due to their own weight. When the screen core support 4 reaches the end of the feeding track 12, it can be limited, that is, the screen core support 4 will not automatically slide out from the feeding track 12.

[0022] The end baffle 13 is arranged at one end of the frame 11 in the length direction, and plays the role of limiting one end of the screen core support 4. By driving the cylinder to adjust the baffle 14 to push the screen core support 4, multiple screen core supports 4 can be flush, and the two ends are aligned, that is, multiple screen core supports 4 can be moved one by one to the positioning welding device 2, which improves the accuracy of movement and is also conducive to the positioning welding device 2 to receive the screen core support 4 output from the feeding track 12. It should be noted that the cylinder driving the adjusting baffle 14 only plays the role of pushing and aligning multiple screen core supports 4, and cannot limit the screen core support 4 to be fixed on the feeding track 12. By adjusting the position of the cylinder driving the adjusting baffle 14, it can adapt to the pushing and welding of screen core supports 4 of different lengths. The cylinder-driven adjustment baffle 14 includes two rails 141, two first sliders 142, a baffle 143 and a push-up cylinder 144. The two rails 141 are arranged in parallel at the upper end of the frame 11, and the push-up and retracting direction thereof is along the length direction of the frame 11. The two first sliders 142 are respectively slidably connected to the two rails 141. The baffle 143 is arranged at the upper end of the two first sliders 142. The cross section of the baffle 143 is L-shaped. One end of the push-up cylinder 144 is connected to the upper end of the frame 11, and the other end is connected to the baffle 143. It can push the baffle 143 to move, so that the baffle 143 can push multiple screen core supports 4 at the same time, so that the screen core supports 4 are limited between the end baffle 13 and the baffle 143. After the baffle 143 pushes multiple screen core supports 4, it can retract to release the limit of the screen core support 4. At this time, the screen core support 4 should be able to roll automatically on the feeding track 12. A baffle 143 is connected to one end of the feeding track 12 away from the positioning welding device 2 , and the baffle 143 serves to block and limit the screen core support 4 to prevent the screen core support 4 from sliding off the feeding track 12 .

[0023] The feeding opening and closing device 15 includes an angle cylinder 151 and a toggle plate 152. The toggle plate 152 is connected to the rotating end of the angle cylinder 151 and rotates with the angle swing of the angle cylinder 151. The toggle plate 152 plays the role of toggling the screen core support 4 to the positioning welding device 2. The positioning welding device 2 can be set at a position obliquely below the feeding opening and closing device 15, and its height is higher than the height of the finished product recovery device 3, that is, it can guide the welded screen core support 4 to the finished product recovery device 3. The toggle plate 152 is in a right angle shape and has two forks, one vertical and the other horizontal, which can block and limit the screen core support 4 located on the feeding track 12. When the angle cylinder 151 rotates, the toggle plate 152 rotates in the direction of the positioning welding device 2. At this time, the toggle plate 152 can toggle a screen core support 4 close to the positioning welding device 2 to move toward the positioning welding device 2. At this time, after toggling, it can play a role in blocking and limiting the second screen core support 4. Each time it is toggled, only one screen core support 4 can be toggled. After the first screen core support 4 is toggled, the angle cylinder 151 is rotated in the opposite direction, which can block and limit the second screen core support 4. By reasonably controlling the operation of the angle cylinder 151, the operation of the positioning welding device 2 can be matched, and the assembly welding speed can be matched, so that the automatic loading of the screen core support 4 is realized.

[0024] In some embodiments, see Figures 1 to 13 The feeding device 1 also includes a limit adjustment device 16, which is connected to the upper end of the frame 11 and is suitable for limiting the position of the cylinder driving the baffle 14. The limit adjustment device 16 is used in conjunction with the push-out cylinder, and includes a plurality of proximity switches arranged at intervals along the moving direction of the baffle. The proximity switch is arranged at the position where the baffle needs to stop. The proximity switch is electrically connected to the cylinder solenoid valve. By transmitting a signal to the cylinder solenoid valve, the operation of the push-out cylinder can be reasonably controlled, so that the baffle can be controlled at a reasonable operating position, thereby realizing the automatic adjustment of the distance between the baffle and the end baffle 13.

[0025] In some embodiments, see Figures 1 to 13, the end of the feeding track 12 close to the positioning welding device 2 is telescopically connected with an extended track 17, the length direction of the extended track 17 is along the length direction of the feeding track 12, and the side of the extended track 17 is connected with a cylinder 18, which is suitable for driving the extended track 17 to extend and retract in the feeding track 12 to adjust the telescopic length of the extended track 17, and the extended track 17 extends when the screen core support 4 is moved to the positioning welding device 2, and the extended track 17 retracts when the welded screen core support 4 moves to the finished product recovery device 3. In the present invention, the movement of the screen core support 4 from the feeding track 12 to the positioning welding device 2 is called loading, and the movement from the positioning welding device 2 to the finished product recovery device 3 is called unloading. By setting the extended track 17, it can play the role of extending when loading, retracting when unloading, and driving the finished product recovery device to recover the finished product of the screen core support 4 after welding, so that the finished product is recovered to the finished product recovery device 3. Among them, the setting of the extended track 17 does not affect the loading and unloading operations of the screen core support 4. One end of the cylinder 18 is connected to the side of the loading track 12, and the other end is connected to the side of the extension track 17, so as to push the extension track 17 to extend and retract.

[0026] In some embodiments, see Figures 1 to 13The positioning welding device 2 includes a base frame 21, a base 22, a first support 23, a driving device 24, a second support 25 and a positioning assembly 26; the base frame 21 is arranged on the side of the feeding device 1; the base 22 is connected to the upper end of the base frame 21; the first support 23 is fixedly connected to the upper end of the base 22; the driving device 24 is connected to the upper end of the base 22 and has a movable end with a degree of freedom of movement parallel to the axial direction of the screen core support 4; the second support 25 is connected to the movable end of the driving device 24, and can move parallel to the axial direction of the screen core support 4 with the help of the driving device 24 Axial movement to adjust the distance between the first support 23, the inner side walls of the first support 23 and the second support 25 close to each other are respectively connected with end plates 5 for welding with the screen core support 4; the positioning assembly 26 is connected to the upper end of the base 22 and is located between the first support 23 and the second support 25. The positioning assembly 26 is used to support the screen core support 4 removed from the feeding device 1, and the driving device 24 drives the second support 25 to move so that the two end plates 5 are respectively abutted against the two ends of the screen core support 4 to form a clamping fixation for the screen core support 4. In this embodiment, the height of the base frame 21 can be adjusted to be suitable for adjusting the height of the screen core support 4 received from the feeding device 1. The position of the first support 23 remains stationary, while the position of the second support 25 can be moved and adjusted. The second support 25 can be driven to move by the driving device 24, thereby adjusting the distance between the first support 23, so that the screen core support 4 can be clamped and fixed, which is conducive to welding operations. The screen core support 4 moved by the fork from the feeding track 12 falls onto the positioning assembly 26, and then the second support 25 is moved to clamp the screen core support 4, thereby fixing the screen core support 4 and the two end plates 5, which is convenient for welding. The screen core support 4 that falls onto the positioning assembly 26 is not easy to slip off the positioning assembly 26. At this time, after the screen core support 4 is clamped, the positioning assembly 26 can be kept away from the screen core support 4, which is convenient for assembly welding. The first support 23 and the second support 25 are symmetrically arranged, and the side connected to the end plate 5 is a vertical plate, and the end plate 5 is connected to the vertical plate. The movement of the vertical plate can make the end plate 5 gradually approach and abut the screen core support 4. By reasonably controlling the moving distance of the driving device 24, the degree of clamping of the screen core support 4 can be controlled.

[0027] Specifically, the driving device 24 is driven by a ball screw, including a vertical plate 241, a bottom plate 242, a slide rail 243, a second slider 244, a screw 245, a screw seat, and a first servo motor 246. The vertical plate 241 is connected to the upper end of the second slider 244. The vertical plate 241 is vertically arranged and used to connect the end plate 5. The slide rail 243 is arranged on the bottom plate 242. The second slider 244 is slidably connected to the slide rail 243. The screw seat is threadedly connected with the screw 245. The screw seat is connected to the second slider 244. The rotation of the screw 245 can drive the second slider 244 to move, thereby driving the vertical plate 241 to move. The power output end of the first servo motor 246 is connected to one end of the screw 245 and is used to drive the screw 245 to rotate. By reasonably controlling the rotation of the first servo motor 246, the moving distance of the vertical plate 241 can be controlled, so that the pushing and clamping of the screen core support 4 can be realized.

[0028] In order to realize the circumferential rotation of the screen core support 4, a welding manipulator (which is a prior art and used for welding operations) can be used to perform circumferential welding. In some embodiments, refer to Figures 1 to 13 , the inner wall of the first support 23 close to the second support 25 is connected to a cycloidal pinwheel reducer 27, the side of the first support 23 away from the cycloidal pinwheel reducer 27 is connected to a second servo motor 28, the power output end of the second servo motor 28 is connected to the input end of the cycloidal pinwheel reducer 27 and is used to drive the cycloidal pinwheel reducer 27 to rotate, and the output end of the cycloidal pinwheel reducer 27 is used to connect the end plate 5; the inner wall of the second support 25 close to the first support 23 is connected to a bearing seat 29, the bearing seat 29 is connected to another end plate 5 and the end plate 5 can rotate circumferentially with the help of the bearing seat 29, and the screen core support 4 can rotate circumferentially with the help of the second servo motor 28 after abutting against the end plates 5 at both ends. The above-mentioned reducer is a prior art, which can realize the circumferential rotation of the driving screen core support 4, thereby facilitating the welding operation. The reducer can be driven by the second servo motor 28 to operate, thereby driving the screen core support 4 and the two ends to rotate simultaneously, and can cooperate with the welding manipulator for welding, thereby improving the welding operation efficiency. In this embodiment, the power output end of the second servo motor 28 can pass through the first support 23. The height of the reducer is the same as the height of the bearing seat 29, so that the screen core support 4 can be horizontal, which is conducive to the assembly welding with the end plate 5. One end plate 5 rotates on the reducer, and the other end plate 5 rotates on the bearing seat 29. The screen core support 4 and the end plate 5 can be driven by the second servo motor 28 to achieve simultaneous rotation, so that welding can be carried out in conjunction with the welding manipulator. At this time, welding can be achieved without rotating the welding manipulator circumferentially around the screen core support 4, thereby improving welding efficiency and quality.

[0029] In some embodiments, see Figures 1 to 13The positioning assembly 26 includes a telescopic cylinder 261, a support seat 262 and an electromagnet 263. The telescopic cylinder 261 is connected to the upper end of the base 22 and has a vertical telescopic freedom. The support seat 262 is connected to the upper end of the telescopic cylinder 261 and can be raised and lowered by means of the telescopic cylinder 261. The support seat 262 is suitable for supporting the screen core support 4. When the screen core support 4 rotates circumferentially, the telescopic cylinder 261 retracts. The electromagnet 263 is connected to the support seat 262, and the electromagnet 263 is used to magnetically attract and limit the screen core support 4. The telescopic cylinder 261 can be telescopically adjusted. In this embodiment, two positioning assemblies 26 are arranged at intervals, and both can support the screen core support 4 at the same time. At the same time, the screen core support 4 can rotate circumferentially on the positioning assembly 26. The screen core support 4 pulled out from the feeding track 12 falls to the upper end of the support seat 262. At this time, the support seat 262 can limit the screen core support 4 and prevent the screen core support 4 from slipping off or leaving the support seat 262 again. In this embodiment, the support seat 262 is U-shaped, which can make the screen core support 4 stuck therein, and plays a role in limiting the screen core support 4. By controlling the extension and contraction of the telescopic cylinder 261, the height of the support seat 262 can be adjusted, so that the supporting height of the screen core support 4 can be adjusted. By setting an electromagnet 263 on the side of the support seat 262, since the screen core support 4 is an iron component and can be magnetically attracted by a magnet, the electromagnet 263 can be set to magnetically attract and position the screen core support 4 that falls on the support seat 262 after being energized, further limiting the movement of the screen core support 4 and the effect of jumping out of the support seat 262.

[0030] Preferably, two circular tubes 264 are spaced apart at the upper end of the support seat 262, and a space for accommodating the screen core support 4 is formed between the two circular tubes 264. The screen core support 4 can rotate circumferentially between the two circular tubes 264. The contact form between the two circular tubes 264 and the screen core support 4 is line contact, which can reduce the friction between the two and make it easy for the screen core support 4 to rotate circumferentially.

[0031] A stopper 210 for supporting the end plate 5 is also provided near the first support 23 and the second support 25. The stopper 210 can support the end plate 5 and effectively prevent the end plate 5 from falling off the first support 23 or the second support 25. Its structure is similar to that of the positioning assembly 26, which is used to support the end plate 5. When the two end plates 5 and the screen core support 4 are clamped and fixed, the stopper 210 and the positioning assembly 26 can be retracted to not contact the end plate 5 and the screen core support 4, which is beneficial to the circumferential rotation of the end plate 5 and the screen core support 4.

[0032] In some embodiments, see Figures 1 to 13The finished product recovery device 3 includes a recovery track 31 and a flap assembly 32; the recovery track 31 is connected to the middle of the frame 11 and is located below the storage area. One end of the recovery track 31 is set in an arc shape and extends out of one side of the frame 11. The recovery track 31 is suitable for storing the welded screen support 4 and the upper end forms a finished product area; the flap assembly 32 is connected to the cylinder 18. When the cylinder 18 contracts, it drives the flap assembly 32 to rotate, so that the flap assembly 32 moves the welded screen support 4 located on the positioning welding device 2 and guides the screen support 4 to move onto the recovery track 31. Figure 5 As shown in , the recovery track 31 is arranged in three groups in parallel, and its upper end can support and store multiple finished product screen core supports 4 at the same time. It is arranged below the storage area and located in the middle of the frame 11. Specifically, the flap assembly 32 is connected to the extended track 17, and the cylinder 18 can control the extension and contraction of the extended track 17, thereby controlling the rotation of the flap assembly 32 and the movement of the finished product screen core support 4. In this embodiment, the extended end of the recovery track 31 is arranged in an arc shape, which can prevent the finished product screen core support 4 from rolling off the recovery track 31, and also plays a role in guiding the rolling of the finished product screen core support 4, that is, when the batches of screen core supports 4 fall on the arc structure, they can automatically roll toward the inner side of the frame 11. A limiting member 210 is also arranged at the inner end of the recovery track 31, and the limiting member 210 is used to limit the finished product screen core support 4 from rolling off the recovery track 31.

[0033] In some embodiments, see Figures 1 to 13 The finished product recovery device 3 further includes a cylinder assembly 33 and a paddle 34; the cylinder assembly 33 is connected to the frame 11; the paddle 34 is connected to the top of the cylinder assembly 33, and the paddle 34 is used to paddle the screen core support 4 toward the inner side of the frame 11, and the flap assembly 32 and the cylinder assembly 33 operate alternately. One end of the cylinder assembly 33 is connected to the frame 11, and the other end is connected to the paddle 34. Through the extension and contraction of the cylinder assembly 33, the paddle 34 can be pushed to move, so that the paddle 34 can paddle the finished product screen core support 4 located on the recovery track 31 to move toward the inner side of the frame 11.

[0034] Preferably, the lower end of the paddle 34 is hinged to the frame 11, and one end of the cylinder assembly 33 is hinged to the middle of the paddle 34. The paddle 34 can be rotated by pushing and retracting the cylinder assembly 33, so that the finished product screen core support 4 can be moved on the recovery track 31. When unloading, the cylinder assembly 33 is not operated at this time, and the paddle 34 is horizontal at this time, which does not affect the unloading operation. When the unloading is completed, when it is necessary to move the finished product screen core support 4 toward the inner side of the frame 11, the paddle 34 can be used to move the finished product screen core support 4 located at the outermost side.

[0035] In some embodiments, see Figures 1 to 13The flap assembly 32 includes a connecting rod 321 and a discharge flap 322; one end of the connecting rod 321 is connected to the end of the extended track 17 away from the loading track 12; the lower end of the discharge flap 322 is hinged to the positioning welding device 2, and the middle part is hinged to the other end of the connecting rod 321. The discharge flap 322 is linked with the connecting rod 321. The discharge flap 322 is placed under the screen support 4 on the positioning welding device 2. When the cylinder 18 contracts, it pulls the connecting rod 321 to move, and the connecting rod 321 pulls the discharge flap 322 to rotate. The discharge flap 322 is used to move the screen support 4 from the positioning welding device 2, so that the screen support 4 is separated from the positioning welding device 2 and rolls on the discharge flap 322 to the recovery track 31. Fig.13 As shown in , when unloading is required, the cylinder 18 is used to shrink and pull the connecting rod 321 to move. At this time, the connecting rod 321 pulls the unloading flap 322 to rotate, and the upper end of the unloading flap 322 can move the finished screen core support 4. At this time, the second support 25 can release the clamping of the screen core support 4, and the screen core support 4 can be moved by the unloading flap 322. After the unloading flap 322 is moved, the screen core support 4 falls on the unloading flap 322, and then passes through the area between the two connecting rods 321, and finally falls on the recovery track 31. Since the extended track 17 is set to two, the cylinder 18 and the connecting rod 321 are also set to two, and they run at the same time. One end of the two connecting rods 321 is hinged to the middle part of the unloading flap 322. Then, by pulling the unloading flap 322, the unloading flap 322 can be rotated, and the finished screen core support 4 located on the positioning welding device 2 can be moved. The connecting rod 321 is U-shaped, and the unloading flap 322 is π-shaped. When the recovery track 31 is full of screen core supports 4, a forklift can be used to clear the screen core supports 4 for reuse.

Step three: adjust the corner cylinder 151 of the feeding opening and closing device 15 to the initial state, and stack the round tube of the vibrating screen core support 4 on the feeding track 12. Step four: set the value in the control program according to the length of the vibrating screen core support 4 to be made. Step five: install the end plate 5 of the vibrating screen core support 4 on the first support 23 and the second support 25 respectively, and extend the telescopic cylinders 261 of the positioning assembly 26 to position. Step six: The cylinder 18 of the feeding track 12 extends to drive the extension track 17 to extend. The feeding opening and closing device 15 is started to push the bottommost vibrating screen sieve core support 4 round tube out of the feeding track 12, and it falls on the positioning assembly 26, and the electromagnet 263 is energized for adsorption. Step 7: The driving device 24 is running, and the position of the second support 25 is adjusted so that the end plate 5 and the sieve core support 4 are fixed. Step 8: Use the welding manipulator to spot weld and fix the end plate 5 and the sieve core support 4. Step 9: The telescopic cylinder 261 of the positioning assembly 26 is contracted, and the reducer on the first support 23 is rotated in conjunction with the welding manipulator to rotate the end plate 5 and the sieve core support 4 in the circumferential direction, and the welding manipulator is used for welding. Step 10: The telescopic cylinder 261 of the positioning assembly 26 extends and holds the sieve core support 4, so that the driving device 24 is away from the sieve core support 4, and the cylinder 18 of the extended track 17 of the feeding track 12 is contracted to drive the unloading flap 322 to lift, and the welded sieve core support 4 is pushed into the recovery track 31 of the finished product recovery device 3. Step 11: The cylinder assembly 33 of the finished product recovery device 3 is operated, so that the paddle 34 pushes the welded screen core support 4 to the rear of the recovery track 31 (in the direction extending to the inner side of the frame 11). The above is the welding operation steps of a screen core support 4 and two end plates 5. Repeat this set of steps to complete the welding of the required number of screen core supports 4.
