Description

Technical Field

[0002] The injection screw is an important component of the injection molding machine. Its function is to convey, compact, melt, stir and pressurize the plastic, all of which are accomplished by the rotation of the screw in the barrel.

[0003] In the past, for the production and processing of injection screws with large diameter, long length, variable diameter, variable pitch, large lead, and variable tooth type used in large extruders, the staff first needed to lift the blanks through the gantry crane and transport them to the processing site, and then use the thread processing equipment to tap the outer wall of the screw to form a thread segment, and then lift the screw after thread processing to the grinding equipment for fine grinding of the thread segment. The traditional grinding method is mostly manual grinding, which has low efficiency and low processing accuracy. In addition, due to the long length and heavy weight of the screw, each lifting requires a lot of manpower. In addition, tapping and grinding the screw in different equipment requires multiple alignment work, and the operation is relatively complicated and may produce certain errors, which will affect the processing accuracy of the screw. On the other hand, the method of loading the screw blank by lifting is relatively complicated. The staff needs to fix the screw blank on the hook first, and then transport it from the top to the corresponding position, position it, and then remove it. This loading method is relatively inconvenient, and there may be dangers during the lifting process, which is not conducive to the safe work of the staff.

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0022] Embodiment 1 Please refer to Figure 1-17 The present invention provides an injection screw processing device, which includes a chassis 500. Loading and unloading parts 100 are arranged on both sides of the bottom of the inner side of the chassis 500 for loading the screw blank. The loading and unloading parts 100 include a material taking and unloading mechanism and a lifting and transporting mechanism. A transfer part 400 is arranged inside the chassis 500 and between the loading and unloading parts 100 on both sides for transferring the screw blank and the semi-finished products. A rotating driving part 200 is installed on the top of the chassis 500 and on both sides of the transferring part 400 for driving the screw to rotate during the processing. A displacement driving part 300 is arranged on the top of the chassis 500 and on both sides of the two rotating driving parts 200. A tool assembly 311 and a grinding assembly 312 are respectively installed on the displacement driving parts 300 on both sides. 12. Specifically, the structural design of the loading and unloading part 100 realizes automatic loading and unloading, and the staff does not need to perform operations such as lifting the screw. The staff loads the blank and unloads the finished screw at a lower position, which greatly reduces the operating difficulty of the staff and facilitates the material loading and unloading, thereby improving production efficiency. The structural design and coordination of the rotating drive part 200, the displacement drive part 300 and the transfer part 400 realize automatic transfer and processing. During the transfer process, no manual operation and alignment are required, and the automatic production of injection molding screw processing is realized, which greatly improves production efficiency, reduces labor intensity, improves operation safety, and ensures processing accuracy, thereby improving the product quality of the screw.

[0023] Please refer to Figure 5-13The two ends of the inner side of the chassis 500 are fixed with fixed plates 501, and the material taking and unloading mechanism includes a feeding drive plate 101 rotatably connected to one end of the two fixed plates 501 close to each other, and a feeding cylinder 113 is installed on one side of the fixed plates 501 close to each other and above the feeding drive plate 101, and the output end of the feeding cylinder 113 is rotatably connected to the feeding drive plate 101 located on the same side, and a second transmission rod 114, a first connecting rod 102 and a first transmission rod 108 are arranged in sequence between the feeding drive plates 101 at both ends from the inside of the chassis 500 to the outside, and the first connecting rod 102 is connected to the feeding drive plate 108. The movable plate 101 is fixedly connected, the second transmission rod 114 and the first transmission rod 108 are both rotatably connected to the feeding drive plate 101, a plurality of feeding plates 103 are fixed on the outside of the first connecting rod 102, the second transmission rod 114 and the first transmission rod 108 pass through the plurality of feeding plates 103 and are rotatably connected thereto, a receiving groove is provided at one end of the feeding plate 103 close to the second transmission rod 114, a pick-up and discharge angle plate 107 is provided inside the receiving groove, and the pick-up and discharge angle plate 107 is fixed on the outside of the second transmission rod 114, a second driving motor 115 is installed on one of the feeding drive plates 101, and the second driving motor 115 is installed on the second driving motor 115. The output end of 15 and the outer side of the end of the second transmission rod 114 are fixed with a second pulley 116, and the outer sides of the two second pulleys 116 are connected with a second transmission belt 117. The loading plate 103 is provided with a loading inclined surface 104, a storage groove 105 and a conveying end surface 106 in sequence from the end away from the loading and unloading angle plate 107 to the direction close to the loading and unloading angle plate 107. Specifically, the loading cylinder 113 is used to drive the loading drive plate 101 to rotate. When the loading drive plate 101 rotates, it will drive a plurality of loading plates 101 through the first connecting rod 102, the second transmission rod 114 and the first transmission rod 108. 03 synchronous movement, the loading plate 103 is used as the loading and unloading transportation track for the screw blank or finished product. When the screw blank needs to be loaded, the staff will carry the blank to the end of the loading plate 103, and push the blank upward along the loading slope 104 to move it to the inside of the storage groove 105, and then the loading cylinder 113 is started to drive the loading drive plate 101 to move, and the loading drive plate 101 drives the loading plate 103 to move and tilt it, so that the blank inside the storage groove 105 moves along the conveying end surface 106 to the end of the loading plate 103 and is blocked by the loading angle plate 107. Fig.11 As shown, when the blank moves to above the loading support roller 123, it stops, and then the second drive motor 115 starts and drives the second transmission rod 114 to rotate through the second pulley 116 and the second transmission belt 117, thereby driving the pick-up and discharge angle plate 107 to rotate. When the pick-up and discharge angle plate 107 rotates, the blank is gradually pushed, as shown in FIG. Fig.12As shown, the blank can be transported to the loading support roller 123 by the loading angle plate 107, and then the loading cylinder 113 is started again to drive the loading plate 103 to tilt toward the loading support roller 123 so that the loading angle plate 107 is separated from the blank. In this process, the second drive motor 115 is started again to drive the loading angle plate 107 to gradually retract toward the inner side of the loading plate 103. Fig.13 As shown, when the pick-up and discharge angle plate 107 is completely separated from the blank, the loading cylinder 113 is started again to drive the loading plate 103 to reset; when the finished screw needs to be unloaded, the unloading process is opposite to the loading process, and the loading cylinder 113 is first started to move the loading plate 103 to the position as shown in FIG. Fig.13 The second drive motor 115 is then started to drive the pick-up and put-out angle plate 107 to flip out from the inner side of the loading plate 103, and then the loading cylinder 113 is started again to drive the loading plate 103 and the pick-up and put-out angle plate 107 to rotate as a whole in the direction away from the loading support roller 123, so that the pick-up and put-out angle plate 107 gradually moves to the bottom position of the finished screw, and then the second drive motor 115 is started again to drive the pick-up and put-out angle plate 107 to retract and rotate to the inner side of the upper material plate 103, so that the pick-up and put-out angle plate 107 The finished screw product is gradually transferred from the loading support roller 123 to the loading plate 103, and then the loading cylinder 113 is started again to drive the loading plate 103 to move slowly and reset. During this process, the screw blank gradually rolls along the conveying end surface 106 to the position of the storage groove 105. When the loading plate 103 is reset, the staff can take out the finished screw product directly or roll it along the loading slope 104 to the end of the loading plate 103. Before that, the transportation tool can be placed in advance at the end of the loading plate 103.

[0024] Embodiment 2 In the first embodiment, when the screw blank is pushed along the feeding slope 104 to the inner side of the storage groove 105 or the finished screw is taken down from the inner side of the storage groove 105 along the feeding slope 104, manual operation is still required, which still has certain inconveniences. This embodiment is further optimized on the basis of the first embodiment. For details, please refer to Figure 5-13, a first driving motor 110 is installed on one of the feeding driving plates 101, and a first pulley 111 is fixed to the outer side of the output end of the first driving motor 110 and the end of the first transmission rod 108, and a first transmission belt 112 is connected to the outer side of the two first pulleys 111, and a plurality of feeding angle plates 109 are fixed to the outer side of the first transmission rod 108. Specifically, the first driving motor 110 is started and drives the first transmission rod 108 to rotate through the first pulley 111 and the first transmission belt 112. When the first transmission rod 108 rotates, it will drive the feeding angle plate 109 to rotate, and the rotation of the feeding angle plate 109 is used to push the blank or the finished product to move. When the blank needs to be pushed to the inner side of the storage groove 105 along the feeding inclined surface 104, the first driving motor 110 is first started to drive the feeding angle plate 109 to rotate in the direction away from the feeding support roller 123, so that it is away from the plate on the side of the feeding support roller 123. The surface moves to a nearly horizontal state, and then the staff transports the blank to the horizontal plate surface of the loading angle plate 109, and then the first drive motor 110 is started again to drive the loading angle plate 109 to rotate in the direction close to the pick-up and discharge angle plate 107. In this process, the loading angle plate 109 will push the blank to move along the loading inclined surface 104 to the inner side of the storage groove 105; when the finished product needs to be unloaded, the first drive motor 110 first starts to drive the loading angle plate 109 to move the plate surface close to the pick-up and discharge angle plate 107 to a position lower than the conveying end surface 106. When the finished screw moves along the conveying end surface 106 to the inner side of the storage groove 105 and the loading plate 103 is reset, the first drive motor 110 can be started again to drive the loading angle plate 109 to rotate in the direction away from the pick-up and discharge angle plate 107, so that the loading angle plate 109 slowly supports the finished screw along the loading inclined surface 104 to complete the unloading; It should be noted that when the loading angle plate 109 moves from the plate surface close to the side of the picking and unloading angle plate 107 to below the conveying end surface 106, the plate surface away from the side of the picking and unloading angle plate 107 is tilted, which can prevent the finished screw from falling out of the storage groove 105 due to excessive speed when rolling along the conveying end surface 106 to the inner side of the storage groove 105, and the loading angle plate 109 has a blocking effect.

[0025] Embodiment 3 Please refer to Figure 5-7The lifting and transporting mechanism includes a support plate 118 arranged on the inner side of the chassis 500 and located at one end of the loading plate 103 close to the pick-up and discharge angle plate 107. The inner sides of both ends of the support plate 118 are threadedly connected with first threaded rods 119. The first threaded rods 119 are rotatably connected to the chassis 500. A third drive motor 120 is installed on the chassis 500 and located at one end away from the tops of the two first threaded rods 119. A third pulley 121 is fixed to the output end of the third drive motor 120 and the outer side of the top of the first threaded rod 119. The outer sides of the two third pulleys 121 are connected to third transmission belts 122. A plurality of pairs of loading support rollers 123 are arranged in pairs at the top of the plate 118 and below the pick-up and discharge angle plate 107. Specifically, when it is necessary to load and unload the finished screw product or blank, the third drive motors 120 at both ends are started synchronously and drive the first threaded rod 119 to rotate through the third pulley 121 and the third transmission belt 122, thereby driving the support plate 118 to perform lifting movement, and then driving the screw blank or finished product supported by the loading support rollers 123 to perform lifting movement. A guide rod is provided on the inner side of the chassis 500, and the support plate 118 is slidably connected to the outer side of the guide rod to improve its lifting stability; It should be noted that the method of controlling the rotation of twin screws by dual motors is an existing technology. It is necessary to consider the connection method, rotation direction, speed of the motors and their impact on the rods. In actual use, the appropriate motor type and configuration should be selected according to the required rotation speed, force and stability, and an effective control system should be designed to coordinate the rotation direction and speed of the two motors to achieve the desired rotation effect. No further details will be given here.

[0026] It should be noted that the loading and unloading parts 100 on each side can complete the complete loading and unloading work independently. Therefore, in actual use, one of the loading and unloading parts 100 can be used according to the needs, or the loading and unloading parts 100 on both sides can be used at the same time to improve production efficiency.

[0027] Embodiment 4 This embodiment discloses the structure of the transfer unit 400.

An eighth pulley 403 is fixed to the output end of the seventh driving motor 402. A ninth pulley 404 is fixed to the outer side of the end of the rotating shaft 401 close to the seventh driving motor 402. A seventh transmission belt 419 is connected to the outer side of the eighth pulley 403 and the ninth pulley 404. A plurality of transfer units are arranged on the outer side of the seventh transmission belt 419. Specifically, when the screw needs to be transferred, the seventh driving motor 402 is started to drive the eighth pulley 403 to rotate, and the rotating shaft 401 is driven to rotate through the ninth pulley 404 and the seventh transmission belt 419, thereby driving the transfer unit to rotate, so as to facilitate the transfer of the screw. It should be noted that the transfer unit is disposed between two adjacent groups of feeding support rollers 123 so as to facilitate the grabbing and placement of the screw rods on the feeding support rollers 123 while preventing the feeding support rollers 123 from interfering with the grabbing.

[0028] Please refer to Figure 14-16The transfer unit includes a transfer plate 405 fixed on the outside of the rotating shaft 401, and two groups of pick-and-place modules are cross-staggered on both sides of the transfer plate 405.

[0032] The specific working principle of an injection molding screw processing device provided by the present invention is: When using the present injection molding screw processing device, when the screw blank is loaded, first the first drive motor 110 is started to drive the loading angle plate 109 to rotate in the direction away from the loading support roller 123, so that the plate surface away from the loading support roller 123 moves to a nearly horizontal state, and then the staff transports the blank to the horizontal plate surface of the loading angle plate 109, and then the first drive motor 110 is started again to drive the loading angle plate 109 to rotate in the direction close to the picking and unloading angle plate 107, pushing the blank to move along the loading inclined surface 104 to the inner side of the storage groove 105; then the loading cylinder 113 is started to drive the loading plate 103 to move and tilt it, so that the blank inside the storage groove 105 moves along the conveying end surface 106 to the end of the loading plate 103 and is picked up by the picking and unloading angle plate 10 7 is blocked, and then the second driving motor 115 starts to drive the pick-up and discharge angle plate 107 to rotate, and the blank is transported to the loading support roller 123 through the pick-up and discharge angle plate 107, and then the loading cylinder 113 starts again to drive the loading plate 103 to tilt toward the loading support roller 123 so that the pick-up and discharge angle plate 107 is separated from the blank. During this process, the second driving motor 115 starts again to drive the pick-up and discharge angle plate 107 to gradually retract toward the inner side of the loading plate 103. When the pick-up and discharge angle plate 107 is completely separated from the blank, the loading cylinder 113 starts again to drive the loading plate 103 to reset; then the third driving motors 120 at both ends are synchronously started to drive the support plate 118 to perform lifting movement, thereby driving the screw blank supported by the loading support roller 123 to move to the end position of the clamp mechanism; When the blank is transported, the clamping mechanism located at the blank position starts the corresponding eighth drive motor 414 to drive the corresponding displacement plate 406 to perform displacement movement so that the clamping claws 411 extend to both sides of the blank, and then the adjusting cylinder 407 starts to drive the adjusting top block 409 to perform displacement movement so that it approaches the rotating column 412 and gradually inserts it between the two rotating columns 412, so that the two rotating columns 412 are gradually separated and maintained, at this time the reset spring 413 is compressed, and at the same time the two clamping claws 411 approach each other to clamp the screw, so as to complete the clamping of the blank, and then the eighth drive motor 414 is started again to drive the screw clamped by the clamping claws 411 to retract into the corresponding transfer groove 417 On the side, then the seventh driving motor 402 starts to drive the transfer plate 405 to rotate 45 degrees and move one station, and then the eighth driving motor 414 starts to drive the blank clamped by the clamping jaws 411 to extend, so that the blank is located between the rotating driving part 200 close to the side of the tool assembly 311, and then the second displacement cylinder 208 and the first displacement cylinder 201 start to drive the auxiliary clamping column 210 and the chuck 205 to approach the blank and clamp the blank, and then the corresponding adjusting cylinder 407 starts to drive the corresponding adjusting top block 409 to retract, and at this time, under the action of the reset spring 413, the clamping jaws 411 release the blank, and at the same time, the eighth driving motor 414 starts to drive the clamping jaws 411 to retract and leave the blank; Then the screw is processed by the displacement drive unit 300 and the tool assembly 311. When the thread processing is completed, the transfer work is performed again. At this time, the two clamp mechanisms work simultaneously, one of which clamps the next blank to be processed, and the other clamp clamps the screw to be polished after the thread processing. Then the seventh drive motor 402 is started to move one station again, so that the blank moves to the thread processing station for thread processing, and the screw after thread processing is transferred to the polishing processing station for polishing. Its transfer process is the same as the above-mentioned blank transfer process; When the grinding work is completed, three of the clamping mechanisms work simultaneously, driving the blank, the threaded screw, and the ground screw to the next workstation, where the ground screw is transferred to the unloading workstation. The unloading process is the opposite of the loading process.
