Description

Technical Field

[0001] The invention relates to the technical field of shielding cover production, in particular to a shielding cover forming device for a weighing instrument. Background Art

[0002] In the production process of weighing instrument shielding cover, injection molding technology is widely used. However, the existing weighing instrument shielding cover molding device has some problems to be solved in actual use.

[0003] Injection molding usually requires the use of spiral blades to convey materials to ensure that the materials can be evenly injected into the mold. However, after the production is completed, some materials often remain on the spiral blades. These residual materials will not only affect the purity and quality of the materials produced next time, but may also damage the spiral blades due to long-term accumulation, reducing their service life. At the same time, since the spiral blades are usually located inside the equipment, their structure is relatively complex, making it extremely difficult to clean up the residual materials.

[0004] In addition, the inner wall of the closed model is also prone to residual materials after injection molding. The shape and size requirements of the scale shield are relatively strict, and the residual materials on the inner wall may cause dimensional deviation and surface quality problems of the shield, for example, there may be defects such as bulges and pits, affecting the shielding performance and appearance of the shield. In addition, the inner wall space of the closed model is relatively narrow, and it is difficult for cleaning tools to enter, making the removal of residual materials a challenging task.

[0005] At present, traditional cleaning methods have limited effects and are time-consuming and labor-intensive, which not only increases production costs but also reduces production efficiency, seriously affecting the quality and production progress of scale shielding covers. Therefore, there is an urgent need for a new type of scale shielding cover forming device that can effectively solve the problem of difficult removal of residual materials on the spiral blades and the inner wall of the closed model.

[0010] The outer wall of the cleaning plate is provided with a through hole, the interior of the cleaning plate is provided with an empty slot, one side of the inner wall of the empty slot is fixedly connected with a microrod, and the output end of the microrod is fixedly connected with a baffle.

[0011] Preferably, the sorting mechanism includes a slide rail, which is fixedly connected to one side of the outer wall of the placement table, and the interior of the slide rail is slidably connected to a carrying gripper, and an inner side of the placement table is provided with a limiting groove, and the interior of the limiting groove is rotatably connected to a round roller, and the interior of the limiting groove is slidably connected to a collection frame.

[0014] Preferably, one end of a connecting rope is fixedly connected to one side of the outer wall of the collection frame, and the other end of the connecting rope is fixedly connected to the outer wall of the placement table.

[0015] Preferably, a W-shaped sheet is fixedly connected to one side of the outer wall of the cleaning plate, and the middle portion of the outer wall of the W-shaped sheet is connected to the through hole.

[0016] Preferably, the driven wheel is meshingly connected with the saw teeth.

[0017] Working principle: During the molding process, the material first enters the injection mechanism. Through the specific structure and operation mechanism inside the mechanism, the materials of different components are fully mixed, and then the mixed materials are extruded to make the materials reach a suitable state for subsequent molding operations, and finally the materials are transferred to the fixed mold. During the molding process, the die and the fixed mold cooperate with each other. When the push rod pushes the die to approach the fixed mold, the space between the two gradually decreases, thereby applying pressure to the material injected into the fixed mold, so that the material is extruded and molded in this limited space to form the basic shape of the scale shield. During the injection molding of the shield, the tenon frame and the mortise are engaged to complete the connection between the output end of the servo motor and the long rod, thereby transmitting the torque generated by the servo motor. The long rod drives the spiral piece to rotate, and the material is slowly pushed from the middle of the barrel to the output port of the barrel, and further extruded into the closed mold formed by the die and the fixed mold, thereby completing the injection molding of the shield. The material enters the barrel from the feed trough, and the material passes through the barrel, the stop layer to the inside of the spiral piece in turn to complete the alignment push. When the injection molding of the shielding cover is completed, the telescopic rod 1 is extended, and the output end on one side drives the stop plate to penetrate the feed slot, so that the inside of the barrel forms a closed state. During the extension of the telescopic rod 1, the output end on the other side drives the fixed ring to feed in the direction of the driven wheel until the sawtooth engages with the driven wheel, and the fixed ring drives the bearing on the outside of the long rod to move synchronously, so that the tenon frame and the mortise are separated. At this time, the torque of the servo motor output end is transmitted to the fixed ring through the driven wheel. While the fixed ring rotates, the telescopic rod 2 slowly extends, so that the movement trajectory of the cleaning plate is a spiral line, so that it can slide inside the spiral sheet, thereby completing the cleaning of the residual material inside the spiral sheet. The push of the micro rod on the baffle can complete the blocking and opening of the through hole. When the molding device needs to continue to be used, it only needs to push the residual material inside the spiral sheet to the output end of the barrel. At this time, the baffle and the through hole are relatively staggered, so that the W-shaped sheet only completes the relative movement of the residual material inside the barrel.When the molding device is no longer in use, it is necessary to clean the barrel and the residual materials inside the die and the fixed die. At this time, the baffle and the through hole overlap relatively, so that the cleaning plate spirally rotates to drive the material and air inside the barrel to be discharged from the output port. This part of the air flows through the barrel output port, the material output pipe inside the closed model and the molding groove of the closed model, so that these parts of the material are synchronously transmitted to the die and the fixed die, thereby completing the thorough cleaning of the material. When there are too many residual materials, the cleaning plate can be sealed during feeding and released during retraction, so as to complete multiple air impacts in the material channel. When the shielding cover is injection molded, the handling gripper is responsible for the transportation of the molded shielding cover. When cleaning the residual material in the closed model, due to the pulling force of the handling gripper, the collection frame will slide in the limit groove until it reaches the bottom of the mold. In this process, the round roller rolls at the bottom of the collection frame, further reducing the friction, so that the collection frame can slide smoothly into place. When the collection frame reaches the bottom of the mold, the collection of residual materials can begin.

[0018] The present invention provides a weighing instrument shielding cover forming device, which has the following beneficial effects:

[0019] 1. The present invention can effectively clean the residual materials in the injection mechanism through the cleaning component. After the injection molding of the shielding cover is completed, the coordinated operation of the cleaning component can clean the residual materials inside the spiral blade, which helps to avoid the residual materials from affecting the next molding and ensure the consistency of the material quantity and state during each molding, thereby maintaining the molding accuracy.

[0020] 2. The present invention can realize relative transmission cleaning of the material in the barrel and complete cleaning of the channel through which the injection passes by changing the state of the cleaning plate, thereby effectively avoiding waste of materials and making the cleaning of materials very convenient.

[0021] 3. The present invention can prevent the corrosion or clogging of equipment parts by the residual materials inside the injection mechanism through the cleaning component. By regularly cleaning the cleaning component, the good condition of each part of the equipment can be maintained and the service life of the equipment can be extended.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 are within the scope of protection of the present invention.

[0033] The output end of the push rod 1 3 is fixedly connected with a push layer 34, the outer wall of the fixed mold 4 is fixedly connected to the push layer 34, one side of the outer wall of the push layer 34 is fixedly connected with one end of the push rod 2 35, and the other end of the push rod 2 35 is fixedly connected with an extrusion frame 36, and the extrusion frame 36 passes through the fixed mold 4;

[0034] Specifically, during the molding process, the material first enters the injection mechanism, and through the specific structure and operation mechanism inside the mechanism, the materials of different components are fully mixed, and then the mixed material is extruded to make the material reach a suitable state for subsequent molding operations, and finally the material is transferred to the fixed mold 4. This transmission process needs to ensure that the flow rate, pressure and other parameters of the material meet the molding requirements to ensure the quality of the final shielding cover. A push rod 3 is fixedly connected to the other end of the outer wall of the placement table 1. The push rod 3 plays an indispensable role in the operation process of the entire molding device. The output end of the push rod 3 is fixedly connected to a push layer 34. The push layer 34 is fixedly connected to the outer wall of the fixed mold 4 on the one hand, and is fixedly connected to one end of a push rod 2 35 on one side of its outer wall on the other hand. The other end of the push rod 2 35 is fixedly connected to an extrusion frame 36, and the extrusion frame 36 runs through the fixed mold 4. During the molding process of the scale shielding cover, the movement of the push rod 1 3 can drive the push rod 2 35 through the push layer 34, and then push the extrusion frame 36. This linkage mechanism is helpful to accurately shape and push the material during the molding process, so that the material is molded in the fixed mold 4 according to the predetermined shape and size, ensuring the shape accuracy and structural integrity of the shielding cover. The interior of the placement table 1 is provided with a fixed mold 4 and a pressing mold 5. The fixed mold 4 is fixedly connected to one side of the outer wall of the placement table 1, and it provides a basic shape framework for the molding of the shielding cover. The pressing mold 5 is arranged at the output end of the push rod 1 3. During the molding process, the pressing mold 5 cooperates with the fixed mold 4. When the push rod 1 3 pushes the pressing mold 5 to approach the fixed mold 4, the space between the two gradually decreases, thereby applying pressure to the material injected into the fixed mold 4, so that the material is extruded and molded in this limited space to form the basic shape of the scale shielding cover.

[0035] The injection mechanism includes a barrel 7, which is fixedly connected to one side of the outer wall of the fixed block 2, and a servo motor 8 is fixedly connected to the other side of the outer wall of the fixed block 2. The output end of the servo motor 8 passes through the fixed block 2 and is fixedly connected to a tenon frame 9. A stop layer 10 is fixedly connected to the inside of the barrel 7, and a spiral sheet 11 is arranged inside the stop layer 10. The spiral sheet 11 is tightly fitted with the inner wall of the stop layer 10, and a long rod 12 is fixedly connected to the inside of the spiral sheet 11. A mortise 13 is opened on one side of the outer wall of the long rod 12. A cleaning component is arranged on one side of the outer wall of the tenon frame 9;

[0036] Specifically, during the injection molding process of the shielding cover, the tenon frame 9 is engaged with the mortise 13 to complete the connection between the output end of the servo motor 8 and the long rod 12, thereby transmitting the torque generated by the servo motor 8. The long rod 12 drives the spiral blade 11 to rotate, and the material is slowly pushed from the inner middle part of the barrel 7 to the output port of the barrel 7, and further extruded into the closed mold formed by the die 5 and the fixed mold 4, thereby completing the injection molding of the shielding cover.

[0037] The cleaning assembly includes a telescopic rod 14, one end of which is fixedly connected to the inner wall layer of the barrel 7, a stop plate 15 is fixedly connected to one side of the output end of the telescopic rod 14, a fixing ring 16 is fixedly connected to the other side of the output end of the telescopic rod 14, a sawtooth 17 is provided inside the fixing ring 16, one end of a connecting plate 18 is fixedly connected to one side of the outer wall of the fixing ring 16, the other end of the connecting plate 18 is fixedly connected to the outer wall of the bearing installed on the outer side of the long rod 12, a driven wheel 19 is fixedly connected to the outer wall of the tenon frame 9, a fixed end of a telescopic rod 20 is fixedly connected to one side of the outer wall of the fixing ring 16, a spiral groove 21 is provided on the outer wall of the stop layer 10, the output end of the telescopic rod 20 extends into the stop layer 10 and is fixedly connected to a cleaning plate 22, the top end of the cleaning plate 22 passes through the spiral groove 21, and the end of the cleaning plate 22 extends into the inner side of the spiral sheet 11;

[0038] One side of the outer wall of the barrel 7 is connected with a feed groove 32, the feed groove 32 is connected with the stop layer 10, the stop plate 15 passes through the end of the feed groove 32, and one side of the outer wall of the stop layer 10 is fixedly connected with a guide ring 33;

[0039] The driven wheel 19 is meshed and connected with the saw teeth 17;

[0040] Specifically, the material enters the barrel 7 from the feed trough 32, and the material passes through the barrel 7 and the stop layer 10 to the inside of the spiral sheet 11 in turn, completing the alignment push. When the injection molding of the shielding cover is completed, the telescopic rod 14 is extended, and the output end on one side drives the stop plate 15 to penetrate the feed trough 32, so that the inside of the barrel 7 forms a closed state. During the extension of the telescopic rod 14, the output end on the other side drives the fixed ring 16 to feed toward the square of the driven wheel 19 until the saw teeth 17 engage with the driven wheel 19, and the fixed ring 16 drives the bearing on the outside of the long rod 12 to move synchronously, so that the tenon frame 9 is disengaged from the mortise 13. At this time, the torque at the output end of the servo motor 8 is transmitted to the fixed ring 16 through the driven wheel 19. While the fixed ring 16 rotates, the telescopic rod 20 slowly extends, thereby making the movement trajectory of the cleaning plate 22 a spiral line, so that it can slide inside the spiral sheet 11, thereby completing the cleaning of the residual material inside the spiral sheet 11.

[0041] The outer wall of the cleaning plate 22 is provided with a through hole 23, and the interior of the cleaning plate 22 is provided with an empty slot 24. A micro-rod 25 is fixedly connected to one side of the inner wall of the empty slot 24, and a baffle 26 is fixedly connected to the output end of the micro-rod 25.

[0042] A W-shaped sheet 38 is fixedly connected to one side of the outer wall of the cleaning plate 22, and the middle part of the outer wall of the W-shaped sheet 38 is connected to the through hole 23;

[0043] Specifically, the push of the baffle 26 by the micro-rod 25 can complete the covering and opening of the through hole 23. When the molding device needs to continue to be used, it is only necessary to push the residual material inside the spiral sheet 11 to the output end of the barrel 7. At this time, the baffle 26 and the through hole 23 are relatively staggered, so that the W-shaped sheet 38 only completes the relative movement of the residual material inside the barrel 7 in the barrel 7. When the molding device is no longer used, it is necessary to clean the barrel 7 and the residual material inside the die 5 and the fixed die 4. At this time, the baffle 26 and the through hole 23 are relatively overlapped, so that the cleaning plate 22 drives the material and air inside the barrel 7 to be discharged from the output port when the cleaning plate 22 spirally rotates. This part of the air flows through the output port of the barrel 7, the material output pipe inside the closed model, and the molding groove of the closed model, so that these parts of the material are synchronously transmitted to the die 5 and the fixed die 4, thereby completing the thorough cleaning of the material, and when there is too much residual material, the cleaning plate 22 can be sealed during feeding and released during retreat, thereby completing multiple air impacts in the material channel.

[0044] The sorting mechanism includes a slide rail 27, which is fixedly connected to one side of the outer wall of the placement table 1, and a carrying gripper 28 is slidably connected inside the slide rail 27. A limiting groove 29 is provided on one side of the placement table 1, and a round roller 30 is rotatably connected inside the limiting groove 29. A collection frame 31 is slidably connected inside the limiting groove 29.

[0045] One end of a connecting rope 37 is fixedly connected to one side of the outer wall of the collecting frame 31, and the other end of the connecting rope 37 is fixedly connected to the outer wall of the placing table 1;

[0046] Specifically, when the shielding cover is injection molded, the transport gripper 28 is responsible for the transportation of the molded shielding cover. When cleaning the residual material in the closed mold, the transport gripper 28 will move to one end of the collection frame 31 according to the program instructions, and then use its gripping device to tightly grasp one end of the collection frame 31. Then, due to the pulling force of the transport gripper 28, the collection frame 31 will slide in the limit groove 29 until it reaches the bottom of the mold. In this process, the round roller 30 rolls on the bottom of the collection frame 31, further reducing the friction force, so that the collection frame 31 can slide smoothly into place. When the collection frame 31 reaches the bottom of the mold, the collection of the residual material can begin. The residual material will be Or with the help of other auxiliary devices, it falls into the collection frame 31. After the collection is completed, the transport gripper 28 retreats and resets again according to the program instructions. At this time, the collection frame 31 begins to move to the initial position under the pulling force of the transport gripper 28. During the movement, since one end of the connecting rope 37 is fixed to the outer wall of the placement table 1, when the collection frame 31 retreats to the initial position, the connecting rope 37 will generate a pulling force on the collection frame 31, so that one end of the collection frame 31 gradually tilts downward under the rotation of the round roller 30. In this process, due to the rotation of the round roller 30, the downward tilting action of the collection frame 31 will be smoother, and due to the limiting effect of the connecting rope 37, the downward tilting angle of the collection frame 31 can also be precisely controlled.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
