The solution of the invention is as follows:
when in use: enough filter screens are placed in the screen storage box of the screen changing box, then the screen changing box is fixedly arranged between the upper guide pipe and the lower guide pipe, and the melt starts to be introduced, as shown in fig. 3 (c1, c2, c3 and c4 represent supports at different positions), when the filter screen at the filtering position (namely the filter screen on the c1 support in fig. 3) is blocked, the filter screen needs to be changed: when the filter screen moves horizontally to the straight groove section from the first coplanar running groove and the second coplanar running groove, the c1 continues to rotate to force the filter screen to make linear displacement in the straight groove section until the c1 rotates to the vertical state (the position of c2 in fig. 3), the motor stops, and the movement is finished; in the motion process of c1, the motion trail of c2 is that c2 rotates clockwise along the hack lever abdicating groove and the outer support plate abdicating groove in the sealing body, so that the filter screen corresponding to the filter screen in the straight groove section is extruded inwards until the highest point of the outer support plate on the c2 bracket descends below the straight groove section, and the corresponding filter screen is completely extruded into the recovery box; c2 only rotates simply and keeps contact with the sealing body when rotating; c3, the movement process is the rotation movement of the simple joint hack lever abdicating groove and the outer support plate abdicating groove; c4 movement process: c4 drives the filter screen contacted with it to move, because the clamping column of the filter screen is the first coaxial running groove and the second coaxial running groove which are coaxial with the arc sealing surface, the filter net on c4 will rotate against the outer and inner brackets on c4 during the process, and during the process, when the c1 is about to separate from the arc sealing surface, the c4 is contacted with the arc sealing surface so as to ensure the effect of filtering the melt, when c4 contacts with the supporting block of the arc sealing surface, the supporting body is pressed into the mounting groove along the inclined surface of the supporting body of the supporting block, when the outer support plate of c4 is higher than the upper surface of the support body, the motor stops, the rotation is finished, the support body can be pressed out by the first return spring in the mounting groove, so as to support the outer support plate with the plane of the upper side thereof being c4, it should be noted that, when c4 stops, the clamping column is just transited from the first coaxial operation groove and the second coaxial operation groove to the first coplanar operation groove and the second coplanar operation groove; when the motor rotation is finished: the telescopic rod is opened, and the telescopic rod can press a clean filter screen in the filter screen storage box onto the empty bracket c 3; at this time, the filter screen is replaced without stopping (after the movement is finished, c1, c2, c3 and c4 are sequentially replaced, and the process is circulated).
The invention can theoretically increase the capacity of the recovery box and the net storage box to improve the times of changing the net, and all the brackets are recycled, all the structures are simple, the net changing quantity is not limited by the structures, and the convenience and the continuity of the net changing without stopping are greatly improved; because the polluted filter screen in the recovery box still has the upward filter surface and no flowing melt exists in the recovery box, the recovered polluted filter screen does not cause secondary pollution.
As a further scheme of the invention: the inner wall outer support plate of the screen changing box is provided with a complete annular rotary groove in a motion profile, horizontal lifting plates are arranged in front and rear side plates of the screen changing box at the initial positions of the first coplanar running groove and the second coplanar running groove in a sliding mode through motion limiting grooves, the upper sides of the motion limiting grooves are far away from a screen changing cavity relative to the lower sides, the lower sides of two ends of each horizontal lifting plate are connected with the screen changing box through second reset springs, the motion cavity of each horizontal lifting plate is communicated with the first coplanar running groove, the second coplanar running groove and the rotary groove, the depth of the motion cavity is larger than that of the first coplanar running groove, the second coplanar running groove and the rotary groove, guide pillars are sleeved at the positions, corresponding to the outer support plate and the rotary groove, of the outer support plate through groove bodies and compression springs, and lifting blocks are arranged at the other ends of the guide pillars in a rotating mode; the lower end of the horizontal lifting plate corresponding to the rotary groove is provided with a lifting groove; the clamping column is an elastic telescopic clamping column, and a wedge-shaped guide plate is fixedly arranged in the position, corresponding to the upper end of the movement limiting groove, in the movement cavity.
In the starting position of c1 in the screen changing process, because the filter plate is approximately horizontal (the filter screen has height and is slightly inclined in fact), the stress is completely provided by the edge of the outer support plate in the initial stage of upward movement along the first coplanar running groove and the second coplanar running groove, so the movement angle of the second coplanar running is small, and the bracket at the position of c1 can be clamped at the beginning due to the fact that the friction force generated by abrasion is large in long-term use, so that the motor is damaged, and screen changing is unsuccessful.
The solution of the scheme is as follows:
when in use: when c1 starts to rotate, the lifting block clamped with the horizontal lifting plate drives the lifting plate to move vertically upwards (the horizontal lifting plate is connected with the motion limiting groove in a sliding manner), the horizontal lifting plate drives the elastic telescopic clamping columns in the first coplanar running groove and the second coplanar running groove to move upwards (at the moment, the upward force applied to the elastic telescopic clamping columns in the second coplanar running groove comes from the forced single vertical upward force of the horizontal lifting plate), when the lifting block continues to rotate, the horizontal lifting block moves inwards along the motion limiting groove, so that the clamping with the elastic telescopic clamping columns and the lifting block is separated (the force for continuously moving upwards after the clamping columns are separated is directly provided by the outer supporting plate, but the transmission angle of the clamping columns in the second coplanar running groove at the moment is sufficiently large), and then the horizontal lifting plate returns to the initial position under the action of the second reset spring; the lifting block on the c1 is pressed back into the rotary groove by the wedge-shaped guide plate along with the rotation (the compression spring is further compressed to accumulate force), and the two clamping columns are respectively pressed back into the first coplanar rotary groove and the second coplanar rotary groove by the wedge-shaped guide plate to continue to move; after c2 moves to the stop position (c1 position of initial state); the lifting block which rotates along the rotary groove can be extruded into the lifting groove (the lower end of the horizontal lifting plate) under the action of the compression spring; therefore, the filter screen clamping device is clamped with the horizontal lifting plate in the motion limiting groove, and the clamping column of the filter screen on the c2 is clamped to the upper end of the horizontal lifting plate. Thereby the horizontal lifting plate can be recycled.
According to the part, the force of the outer support plate is firstly transmitted to the horizontal lifting plate, and the horizontal lifting plate forces the filter screen to keep horizontal movement, so that the technical problem that the transmission angle of the initial position of the second coplanar running groove is small and the filter screen can be clamped after long-term use is solved, the upward movement of the filter screen is more reliable and smooth, and the use efficiency of the invention is improved.
As a further scheme of the invention: the upper end surface of the lifting block is a plane. The flat surface has the function of ensuring the stability of the contact between the lifting block and the horizontal table plate, thereby balancing and stabilizing the stress between the lifting block and the horizontal table plate.
As a further scheme of the invention: the height of the motion limiting groove is lower than the upper end of the arc sealing surface, so that the motion limiting groove can return to the initial position as soon as possible to be clamped with the next support after being separated from contact with the support.
As a further scheme of the invention: the power part is a motor; the motor technology is stable and mature and is easy to obtain.
As a further scheme of the invention: send net device including storing up net box and telescopic link, it includes the casing to store up the net box, there is the clamp plate casing inside through propelling movement spring sliding connection, the extrusion between clamp plate front end and the casing has a plurality of filter screens, trade the net box and store up the position of net box inner casing left side board contact and offer the intercommunication groove of the same thickness such as height with the filter screen, it is provided with the push pedal to slide on the casing upper and lower bottom plate that the intercommunication groove corresponds, the push pedal is sealed external to have the telescopic link, the telescopic link is fixed to be set up store up the net box outside.
When in use: the telescopic rod pushes the filter screen opposite to the telescopic rod to enter the bracket, and after the front end of the telescopic rod returns to the initial position, the pushing spring pushes the next filter screen to be in contact with the shell, so that the next filter screen is convenient to install; the device has the advantages of simple structure, stable use, low price and convenient maintenance.
Compared with the prior art, the invention has the beneficial effects that:
1. the invention can theoretically increase the capacity of the recovery box and the net storage box to improve the times of changing the net, and all the brackets are recycled, all the structures are simple, the net changing quantity is not limited by the structures, and the convenience and the continuity of the net changing without stopping are greatly improved; because the polluted filter screen in the recovery box still has the upward filter surface and no flowing melt exists in the recovery box, the recovered polluted filter screen does not cause secondary pollution.
2. According to the invention, the force of the outer support plate is firstly transmitted to the horizontal lifting plate, and the horizontal lifting plate forces the filter screen to keep horizontal movement, so that the technical problems that the transmission angle of the initial position of the second coplanar running groove is small and the filter screen can be clamped after long-term use are solved, the upward movement of the filter screen is more reliable and smooth, and the use efficiency of the invention is improved.

The solution of the invention is as follows:
when in use: enough filter screen 10 is put into the screen storage box 6 of the screen changing box 1, then the screen changing box 1 is fixedly arranged between the upper guide pipe 2 and the lower guide pipe 3, and melt starts to be introduced, as shown in fig. 3 (c1, c2, c3 and c4 represent supports 15 at different positions), when the filter screen 10 at the filtering position (i.e. the filter screen 10 on the support 15 of c1 in fig. 3) is blocked and then the filter screen 10 needs to be changed: the motor 4 rotates, c1 rotates along the arc sealing surface 13 (c2, c3, c4 also rotate), so that the filter screen 10 on the motor tends to rotate, but under the restriction of the first coplanar rotation groove 18-1-2 and the second coplanar rotation groove 18-2-2, the filter screen 10 can only keep moving upwards in a horizontal state, so that the outer inclined surface 10-4 of the filter screen 10 and the outer support plate 15-2 keep contacting and relatively rotating, the inner inclined surface 10-3 of the filter screen 10 and the inner support plate 15-3 are separated from contacting, when the filter screen 10 moves horizontally to the moment that the clamping column 20 moves from the first coplanar rotation groove 18-1-2 and the second coplanar rotation groove to the straight groove section 18-3, the c1 continues to rotate, so that the filter screen 10 makes a linear displacement in the straight groove section 18-3 until the c1 rotates to a vertical state (c2 position in fig. 3), stopping the motor 4 and finishing the movement; in the c1 movement process, the movement track of c2 is that c2 rotates clockwise along the hack lever abdicating groove 12 and the outer support plate abdicating groove 11 in the sealing body 9, so that the filter screen 10 corresponding to the straight groove section 18-3 is pressed inwards until the highest point of the outer support plate 15-2 on the c2 bracket 15 descends to the lower part of the straight groove section 18-3, and the corresponding filter screen is completely pressed into the recovery box 14; c2 only makes simple rotation thereafter, and when rotated, maintains contact with the sealing body 9; the c3 movement process is the rotation movement of the simple joint hack lever abdicating groove 12 and the outer support plate abdicating groove 11; c4 movement process: c4 drives the filter screen 10 contacted with it to move, because the clamping grooves of the clamping column 20 of the filter screen 10 are the first coaxial running groove 18-1-1 and the second coaxial running groove 18-2-1 which are coaxial with the arc sealing surface 13, the filter screen 10 on the c4 in the process can closely cling to the outer support plate 15-2 and the inner support plate 15-3 on the c4 bracket 15 to make rotary motion, in the process, when the c1 is about to be separated from the arc sealing surface 13, the c4 can be contacted with the arc sealing surface 13 to ensure the effect of filtering the melt, when the c4 is contacted with the supporting block 17 of the arc sealing surface 13, the supporting body 17-2 can be pressed into the mounting groove 17-1 along the inclined plane of the supporting body 17-2 of the supporting block 17, when the outer support plate 15-2 of the c4 is higher than the upper surface of the supporting body 17-2, the motor 4 stops, when the rotation is finished, the supporting body 17-2 is pressed out by the first return spring 17-3 in the mounting groove 17-1, so that the supporting body is supported by the outer supporting plate 15-2 with the plane of the upper side being c4, and it is noted that when c4 stops, the clamping column 20 just transits from the first coaxial operation groove and the second coaxial operation groove to the first coplanar operation groove and the second coplanar operation groove; when the rotation of the motor 4 is finished: when the telescopic rod 5 is opened, the telescopic rod 5 presses a clean filter screen 10 in the screen storage box 6 onto the empty bracket 15c 3; at this time, the filter screen is replaced without stopping (after the movement is finished, c1, c2, c3 and c4 are sequentially replaced, and the process is circulated).
The invention can theoretically increase the capacity of the recovery box 14 and the net storage box 6 to improve the times of changing the net, and all the brackets 15 are recycled, all the structures are simple, the net changing quantity is not limited by the structures, and the convenience and the continuity of changing the net without stopping the machine are greatly improved; because the contaminated filter screen 10 in the recovery box 14 still has its filtering surface facing upwards and no flowing melt is present in the recovery box 14, the recovered contaminated filter screen does not cause secondary contamination.
As a further scheme of the invention: the motion contour of an outer support plate 15-2 on the inner wall of the screen changing box 1 is provided with a complete annular rotary groove 8, the front and rear side plates of the screen changing box 1 at the initial positions of a first coplanar rotary groove 18-1-2 and a second coplanar rotary groove 18-2 are provided with a horizontal lifting plate 21 in a sliding way through a motion limiting groove 22, the upper side of the motion limiting groove 22 is far away from a screen changing cavity 7 relative to the lower side, the lower sides of the two ends of the horizontal lifting plate 21 are connected with the screen changing box 1 through a second return spring 23, the motion cavity of the horizontal lifting plate 21 is communicated with the first coplanar rotary groove 18-1-2, the second coplanar rotary groove 18-2-2 and the rotary groove 8, the depth of the motion cavity is greater than that of the first coplanar rotary groove 18-1-2, the second coplanar rotary groove 18-2-2 and the rotary groove 8, the corresponding position of the outer support plate 15-2 and the rotary groove 8 is sleeved with a guide pillar 25 through a groove body and a compression spring 26, the other end of the guide post 25 is rotatably provided with a lifting block 24; the lower end of the horizontal lifting plate 21 corresponding to the rotary groove 8 is provided with a lifting groove 27; the clamping column 20 is an elastic telescopic clamping column 20, and a wedge-shaped guide plate 19 is fixedly arranged in the position, corresponding to the upper end of the movement limiting groove 22, in the movement cavity.
In the initial position of c1 in the screen changing process, because the filter plate is approximately horizontal (the filter screen 10 has height and is slightly inclined in fact), the stress is completely provided by the edge of the outer support plate 15-2 in the initial stage of upward movement along the first coplanar running groove and the second coplanar running groove, so the movement angle of the second coplanar running groove is small, and the bracket 15 at the position of c1 can be clamped at the initial time due to the fact that the friction force generated by abrasion is large in long-term use, thereby damaging the motor 4 and failing to change the screen.
The solution of the scheme is as follows:
when in use: when the c1 starts to rotate, the lifting block 24 engaged with the horizontal lifting plate 21 will drive the lifting plate to move vertically upwards (the horizontal lifting plate 21 is slidably connected with the motion limiting groove 22), the horizontal lifting plate 21 will drive the elastic telescopic clamping columns 20 in the first coplanar running groove and the second coplanar running groove to move upwards (at this time, the upward force applied to the elastic telescopic clamping column 20 in the second coplanar running groove comes from the forced single vertical upward force of the horizontal lifting plate 21), when the lifting block 24 continues to rotate, the horizontal lifting block 24 will move inwards along the motion limiting groove 22, thereby disengaging from the resilient telescoping post 20 and the lift block 24 (the force of continued upward movement of the post 20 after disengagement is directly provided by the outer support plate 15-2, but now the driving angle of the post 20 in the second coplanar rotation slot has become sufficiently large), and then the horizontal lift plate 21 returns to the starting position under the action of the second return spring 23; the lifting block 24 on the c1 is pressed back into the rotating groove 8 by the wedge-shaped guide plate 19 along with the rotation (the compression spring 26 is further compressed and accumulated with force), and the two clamping columns 20 are also pressed back into the first coplanar rotating groove and the second coplanar rotating groove respectively by the wedge-shaped guide plate 19 to continue to move; after c2 moves to the stop position (c1 position of initial state); the lifting block 24 which originally rotates along the rotary groove 8 is squeezed into the lifting groove 27 (the lower end of the horizontal lifting plate 21) under the action of the compression spring 26; so as to complete the clamping with the horizontal lifting plate 21 in the motion limiting groove 22, and the clamping column 20 of the filter screen 10 on the c2 is clamped on the upper end of the horizontal lifting plate 21. So that the horizontal lifting plate 21 can be recycled.
In the part, the force of the outer support plate 15-2 is firstly transmitted to the horizontal lifting plate 21, and the horizontal lifting plate 21 forces the filter screen 10 to keep horizontal movement, so that the technical problem that the transmission angle of the initial position of the second coplanar running groove is small and the filter screen 10 is clamped after long-term use is solved, the filter screen 10 moves upwards more reliably and smoothly, and the use efficiency of the invention is improved.
As a further scheme of the invention: the upper end surface of the lifting block 24 is a plane. The flat surface serves to ensure stability of the contact between the lift block 24 and the horizontal table plate, thereby equalizing and stabilizing the forces therebetween.
The height of the motion limiting groove 22 is lower than the upper end of the arc sealing surface 13, so that the motion limiting groove 22 can return to the initial position as soon as possible to be clamped with the next bracket 15 after being separated from contact with the bracket 15.
As a further scheme of the invention: the power part is a motor 4. The motor 4 is stable and mature in technology and easy to obtain.
As a further scheme of the invention: the net conveying device comprises a net storage box 6 and a telescopic rod 5, the net storage box 6 comprises a shell 6-1, the interior of the shell 6-1 is connected with a pressing plate 6-3 in a sliding mode through a pushing spring 6-2, a plurality of filter screens 10 are extruded between the front ends of the pressing plates 6-3 and the shell 6-1, a communicating groove 6-5 which is equal to the filter screens 10 in height and thickness is formed in the position, in contact with the left side plate, of the shell 6-1 in the net storage box 6, of the net changing box 1, a push plate 6-4 is arranged on the upper bottom plate and the lower bottom plate of the shell 6-1 corresponding to the communicating groove 6-5 in a sliding mode, the telescopic rod 5 is connected with the push plate 6-4 in a.
When in use: the telescopic rod 5 pushes the filter screen 10 opposite to the telescopic rod to enter the bracket 15, and after the front end of the telescopic rod 5 returns to the initial position, the pushing spring 6-2 pushes the next filter screen 10 to be in contact with the shell 6-1, so that the filter screen 10 is convenient to install next time; the device has the advantages of simple structure, stable use, low price and convenient maintenance.
As a further scheme of the invention: the number of the first bevel gears 12 and the second bevel gears 17 is more than or equal to two; the cooperation of the multiple groups of driving columns 16 and the vibrating chutes 15 can ensure that the vibrating screen plate 7 is stressed stably and uniformly.
The working principle is as follows: enough filter screen 10 is put into the screen storage box 6 of the screen changing box 1, then the screen changing box 1 is fixedly arranged between the upper guide pipe 2 and the lower guide pipe 3, and melt starts to be introduced, as shown in fig. 3 (c1, c2, c3 and c4 represent supports 15 at different positions), when the filter screen 10 at the filtering position (i.e. the filter screen 10 on the support 15 of c1 in fig. 3) is blocked and then the filter screen 10 needs to be changed: the motor 4 rotates, c1 rotates along the arc sealing surface 13 (c2, c3, c4 also rotate), so that the filter screen 10 on the motor tends to rotate, but under the restriction of the first coplanar rotation groove 18-1-2 and the second coplanar rotation groove 18-2-2, the filter screen 10 can only keep moving upwards in a horizontal state, so that the outer inclined surface 10-4 of the filter screen 10 and the outer support plate 15-2 keep contacting and relatively rotating, the inner inclined surface 10-3 of the filter screen 10 and the inner support plate 15-3 are separated from contacting, when the filter screen 10 moves horizontally to the moment that the clamping column 20 moves from the first coplanar rotation groove 18-1-2 and the second coplanar rotation groove to the straight groove section 18-3, the c1 continues to rotate, so that the filter screen 10 makes a linear displacement in the straight groove section 18-3 until the c1 rotates to a vertical state (c2 position in fig. 3), stopping the motor 4 and finishing the movement; in the c1 movement process, the movement track of c2 is that c2 rotates clockwise along the hack lever abdicating groove 12 and the outer support plate abdicating groove 11 in the sealing body 9, so that the filter screen 10 corresponding to the straight groove section 18-3 is pressed inwards until the highest point of the outer support plate 15-2 on the c2 bracket 15 descends to the lower part of the straight groove section 18-3, and the corresponding filter screen is completely pressed into the recovery box 14; c2 only makes simple rotation thereafter, and when rotated, maintains contact with the sealing body 9; the c3 movement process is the rotation movement of the simple joint hack lever abdicating groove 12 and the outer support plate abdicating groove 11; c4 movement process: c4 drives the filter screen 10 contacted with it to move, because the clamping grooves of the clamping column 20 of the filter screen 10 are the first coaxial running groove 18-1-1 and the second coaxial running groove 18-2-1 which are coaxial with the arc sealing surface 13, the filter screen 10 on the c4 in the process can closely cling to the outer support plate 15-2 and the inner support plate 15-3 on the c4 bracket 15 to make rotary motion, in the process, when the c1 is about to be separated from the arc sealing surface 13, the c4 can be contacted with the arc sealing surface 13 to ensure the effect of filtering the melt, when the c4 is contacted with the supporting block 17 of the arc sealing surface 13, the supporting body 17-2 can be pressed into the mounting groove 17-1 along the inclined plane of the supporting body 17-2 of the supporting block 17, when the outer support plate 15-2 of the c4 is higher than the upper surface of the supporting body 17-2, the motor 4 stops, when the rotation is finished, the supporting body 17-2 is pressed out by the first return spring 17-3 in the mounting groove 17-1, so that the supporting body is supported by the outer supporting plate 15-2 with the plane of the upper side being c4, and it is noted that when c4 stops, the clamping column 20 just transits from the first coaxial operation groove and the second coaxial operation groove to the first coplanar operation groove and the second coplanar operation groove; when the rotation of the motor 4 is finished: when the telescopic rod 5 is opened, the telescopic rod 5 presses a clean filter screen 10 in the screen storage box 6 onto the empty bracket 15c 3; at this time, the filter screen is replaced without stopping (after the movement is finished, c1, c2, c3 and c4 are sequentially replaced, and the process is circulated).
