Description

Technical Field

[0001] The present invention relates to the technical field of fork frames, in particular to a separate weighing fork frame. Background Art

[0002] Throughout the development of the industrial sector, material handling has always been a core component, encompassing multiple processes such as material storage, transportation, and mixing. Hoppers, commonly used containers for material storage and transfer, have a significant impact on the entire production process through their connection and operational efficiency across various links. Forks, a key component for efficient hopper operation, emerged and continued to develop in this context.

[0003] Most of the existing fork frames are structures that are set on guide rails and move longitudinally with the guide rails. After being plugged into the weighing plug, they can often only achieve longitudinal movement. However, after the materials are loaded, the loading buckets loaded with materials of different weights often need to be transported to different positions, and then the loading buckets need to be moved so that the materials can be processed. However, the current weighing devices are difficult to transfer the materials after weighing them, so there are certain inconveniences in the later transportation and production of materials. Therefore, we propose a separate weighing fork frame to solve the above problems. Summary of the Invention

The trolley mechanism includes a weighing fork frame body and a loading bucket fixed thereon. Two fork rods are pluggable connected to the weighing fork frame body. The weighing fork frame body is also rotatably connected to two wheel axles, and two rollers are fixedly mounted on the wheel axles.

[0014] Two supporting covers are symmetrically fixed to the bottom of one side of the slide;

[0015] Two weight sensors are respectively arranged in corresponding supporting covers;

[0016] Two pressure rods are symmetrically fixed to one side of the connecting plate and extend into corresponding supporting covers to contact the weight sensor;

[0017] When the two fork rods are plugged into the weighing fork frame body, the connecting plate transmits the pressure to the weight sensor through the pressure rod.

[0018] In a possible design, two second magnet rings are symmetrically provided on one side of the weighing fork frame body, a first magnet ring fixedly connected to the connecting plate is sleeved on the fork rod, and the first magnet ring and the second magnet ring are magnetically attracted to each other.

[0019] In one possible design, the lifting mechanism includes:

[0020] A fixed screw rod is vertically fixed in the slide rail;

[0021] a threaded tube, rotatably connected to a supporting plate and threadably engaged with the fixing screw, wherein the supporting plate is fixed to one side of the slide;

[0022] A power assembly is installed on the supporting plate and is in driving connection with the threaded pipe.

[0023] In one possible design, the power assembly includes:

[0024] a stepping motor, fixed on the supporting plate;

[0025] An active bevel gear is fixed to the output shaft of the stepper motor;

[0026] The driven bevel gear is fixed on the threaded tube and meshes with the driving bevel gear.

[0027] In one possible design, the feeding mechanism further includes:

[0028] Two guide grooves are symmetrically arranged on the top of the support frame;

[0029] The pushing component is arranged in the support frame, and the top of the pushing component extends above the support frame to push the weighing fork frame body.

[0030] In one possible design, the push component includes:

[0031] A servo motor is fixed in the support frame;

[0032] a transmission screw connected to the output shaft of the servo motor;

[0033] The baffle is threadably connected to the transmission screw through a nut and can slide along the movable hole on the support frame.

[0034] In one possible design, it also includes:

[0035] Two electric push rods are symmetrically installed on both sides of the slide;

[0036] The push plate is connected to the output ends of the two electric push rods and is used to push the weighing fork frame body to separate from the fork rod.

[0037] In one possible design, it also includes:

[0038] A mounting frame, fixed to the base frame and rotatably connected to the top of the slide rail;

[0039] A driving motor is fixed on the mounting frame;

[0040] A driving gear is fixed to the output shaft of the driving motor;

[0041] A toothed disc is fixed on the slide rail and meshes with the driving gear.

[0042] In the present application, a trolley mechanism with a loading bucket loaded with materials is placed on a support frame, so that the roller rolls linearly in the corresponding guide groove, and then the servo motor is started to drive the transmission screw to rotate. At this time, under the threaded transmission action with the nut, the baffle can be driven to move, so when the baffle approaches the servo motor, the weighing fork frame body can be pushed to move, so that the two fork rods are plugged into the weighing fork frame body, and when the fork rods are plugged into the weighing fork frame body, the first magnet ring and the second magnet ring can be attracted, so that when the loading bucket is moved longitudinally, the fork rods and the weighing fork frame body can be kept stably connected, and then the active bevel gear is driven to rotate by starting the stepping motor, and at this time, under the meshing transmission action with the driven bevel gear, the threaded tube can be driven to rotate, so that the threaded tube can drive the connecting plate to move longitudinally under the threaded transmission action with the fixed screw, so that the trolley can be moved The mechanism is lifted upward. At this time, the weight of the material in the loading bucket on the trolley mechanism can exert downward pressure on the connecting plate through the fork rod, and the two weight sensors can be pressed respectively by the two pressure rods. The weight sensor can detect the weight of the material put in the loading bucket. After the weight of the material is weighed, the driving motor is started to drive the active gear to rotate. At this time, under the meshing transmission with the gear plate, the slide rail can be driven to rotate, so that the position of the lifted trolley mechanism can be rotated, so that the position of the trolley mechanism can be adjusted, so that the trolley mechanism can be received at the required position. After the position and height adjustment of the trolley are completed, the push plate is driven to move horizontally by starting the two electric push rods, which can form a thrust for the weighing fork frame body, so that the weighing fork frame body moves to a position disengaged from the fork rod, thereby realizing the unloading of the trolley mechanism.

[0043] In the present invention, the separate type weighing fork frame, through the weighing mechanism, can be connected to the two fork rods and the weighing fork frame body, and the sliding plate is lifted upward to lift the weighing fork frame body upward. At this time, the weight of the material loaded in the loading bucket will be transmitted to the two fork rods through the weighing fork frame body, so that the connecting plate can fall downward, and the two weight sensors can be pressed respectively by the two pressure rods, and the weight sensors can detect the weight of the material put into the loading bucket;

[0044] In the present invention, the separate weighing fork frame can be driven to rotate by activating the power assembly through the lifting mechanism. At this time, under the action of the threaded transmission with the fixed screw, the support plate can be driven to move longitudinally. Since the support plate is fixedly connected to the slide plate, it can drive the slide plate to move upward, thereby driving the loading bucket filled with materials to move longitudinally.

[0045] In the present invention, the separate type weighing fork frame can be provided with a support frame through a feeding mechanism to carry out load-bearing and position limiting for the trolley mechanism that needs to carry out load-bearing and transportation, so that the trolley mechanism can maintain linear movement and dock with the two fork rods. Then, the servo motor is started to drive the transmission screw to rotate. At this time, under the action of the threaded transmission with the nut, the baffle can be driven to move. Therefore, when the baffle approaches the servo motor, it can push the weighing fork frame body to move, so that the two fork rods are plugged into the weighing fork frame body.

[0046] The present invention can realize weighing the weight of the trolley mechanism loaded with materials, and after weighing, can adjust the position and height of the trolley mechanism, so that in the actual production and use process, the trolley mechanism loaded with materials can be conveniently transported, so it has good ease of use.

DETAILED DESCRIPTION

[0055] The technical solutions 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, rather than all the embodiments.

[0056] Example 1: Reference Figure 1-7 A weighing fork frame includes a base frame 1, which serves as the basic support structure for the entire fork frame. A support plate 2 is rotatably connected to the base frame 1 via a pin, and the support plate 2 can rotate around the pin to a certain angle. A slide rail 3 is welded to the top of the support plate 2. The slide rail 3 is a long strip structure, and a slide plate 7 is slidably mounted on the slide rail 3. The slide plate 7 can slide longitudinally on the slide rail 3.

[0057] A weighing mechanism is connected to the slide 7. The weighing mechanism specifically includes a connecting plate 14 that is slidably mounted on the slide 7. The slide 7 is provided with a corresponding slide groove in which the connecting plate 14 can slide. Two fork rods 15 are symmetrically welded to one side of the connecting plate 14. The two fork rods 15 are parallel to each other and arranged horizontally. Two support covers 17 are symmetrically welded to the bottom of one side of the slide 7. The support cover 17 is an internally hollow structure. A weight sensor 19 is bonded to the bottom inner wall of the support cover 17. The weight sensor 19 can accurately sense pressure changes. Two pressure rods 18 are symmetrically fixedly mounted on one side of the connecting plate 14. The bottom ends of the pressure rods 18 extend into the corresponding support covers 17 and contact the weight sensors 19. When the two fork rods 15 are connected to the weighing fork frame body 29 and the weighing fork frame body 29 is lifted upward by the slide plate 7, the weight of the material loaded in the loading bucket 30 is transferred to the two fork rods 15 through the weighing fork frame body 29, causing the connecting plate 14 to fall downward. At this time, the two pressure rods 18 respectively press the two weight sensors 19, which can detect the weight of the material placed in the loading bucket 30. In addition, two second magnet rings 31 are symmetrically bonded to one side of the weighing fork frame body 29. The fork rods 15 are equipped with a first magnet ring 16 bonded to one side of the connecting plate 14. The first magnet ring 16 and the second magnet ring 31 are attracted to each other. When the fork rods 15 are connected to the weighing fork frame body 29, the first magnet ring 16 and the second magnet ring 31 are attracted to each other, maintaining a stable connection between the fork rods 15 and the weighing fork frame body 29 when the loading bucket 30 is moved longitudinally.

[0058] The weighing fork frame is also provided with a lifting mechanism mounted on the slide rail 3, which is connected to the slide plate 7 and is used to drive the slide plate 7 to move longitudinally. The lifting mechanism is specifically as follows: a fixed screw 10 is welded inside the slide rail 3 and is vertically arranged. A support plate 8 is welded to one side of the slide rail 7, and one side of the support plate 8 extends into the slide rail 3. The top of the support plate 8 is rotatably connected to a threaded tube 9 located inside the slide rail 3. The threaded tube 9 can rotate around its own axis. The fixed screw 10 passes through the support plate 8 and the threaded tube 9 respectively and is threadedly connected to the threaded tube 9. A power assembly is also mounted on the support plate 8, which is connected to the threaded tube 9. The power assembly includes a stepper motor 11 fixedly mounted on one side of the top of the support plate 8 by bolts. An active bevel gear 12 is fixedly mounted on the output shaft of the stepper motor 11 by a key connection. A driven bevel gear 13 is fixedly mounted on the threaded tube 9 by welding. The active bevel gear 12 meshes with the driven bevel gear 13. When the stepper motor 11 is started, the stepper motor 11 drives the active bevel gear 12 to rotate. Since the active bevel gear 12 is engaged with the driven bevel gear 13, the threaded tube 9 is driven to rotate. At this time, under the action of the threaded transmission with the fixed screw 10, the support plate 8 can be driven to move longitudinally. Because the support plate 8 is fixedly connected to the slide 7, the slide 7 can be driven to move upward, thereby driving the loading bucket 30 filled with materials to move longitudinally.

[0059] A loading mechanism is mounted on the support plate 2, and a trolley mechanism is provided on the loading mechanism. The trolley mechanism includes a weighing fork frame body 29, with a loading bucket 30 welded through it. The loading bucket 30 is used to load materials. A solenoid valve is fixedly mounted at the bottom discharge port of the loading bucket 30. The discharge of materials can be achieved by controlling the opening and closing of the solenoid valve. The bottom of the weighing fork frame body 29 is symmetrically connected to two wheel axles 32 for rotation. Two rollers 33 are symmetrically fixedly mounted on the wheel axles 32 via a key connection, and the rollers 33 can roll on the ground. The loading mechanism specifically includes a support frame 23 welded to the top of the support plate 2. The top of the support frame 23 is symmetrically provided with two guide grooves 24. The guide grooves 24 are elongated grooves. The bottoms of the rollers 33 extend into the corresponding guide grooves 24, allowing them to move laterally and linearly along the guide grooves 24, so that the weighing fork frame body 29 can be plugged into and fitted with the two fork rods 15. A movable hole is provided on the support frame 23, and a pushing assembly is also connected to the support frame 23. The top of the pushing assembly passes through the movable hole and extends to the top of the support frame 23. The pushing assembly is used to push the weighing fork frame body 29 to move. The pushing assembly includes a servo motor 25 fixedly installed in the support frame 23 by bolts. A transmission screw 26 is welded to the output shaft of the servo motor 25. One end of the transmission screw 26 is rotatably connected to the inner wall of the support frame 23 via a bearing. A baffle 27 is slidably connected through the movable hole. The baffle 27 can slide along the movable hole. The baffle 27 is used to push the weighing fork frame body 29 to move, so that the weighing fork frame body 29 is plugged into the two fork rods 15. A nut 28 is welded to the bottom of one side of the baffle 27. The transmission screw 26 passes through the nut 28 and the baffle 27 respectively and is threadedly connected to the nut 28. When the servo motor 25 is started, the servo motor 25 drives the transmission screw 26 to rotate. Since the transmission screw 26 is threadedly connected to the nut 28, the baffle 27 can be driven to move. When the baffle 27 approaches the servo motor 25, it can push the weighing fork frame body 29 to move, so that the two fork rods 15 are plugged into the weighing fork frame body 29.

[0060] The present application can be used in the field of fork frame technology, and can also be used in other fields applicable to the present application.

[0061] Example 2: Reference Figure 1 and 3 , based on the improvement of the first embodiment: a separate type weighing fork frame, which is applied to the field of fork frame technology, has electric push rods 20 fixedly installed on both sides of the slide 7 by bolts. The output shafts of the two electric push rods 20 extend to one side of the slide 7 and are fixedly installed with the same push plate 21 by bolts. When it is necessary to unload the weighing fork frame body 29, the two electric push rods 20 are started, and the electric push rods 20 drive the push plate 21 to move horizontally. At this time, the push plate 21 can generate thrust for the weighing fork frame body 29, so that the weighing fork frame body 29 moves to a position where it is separated from the fork rod 15.

[0062] A mounting bracket 5 is welded to one side of the top of the base frame 1, and the top of the slide rail 3 is rotatably connected to the mounting bracket 5. A drive motor 6 is fixedly installed on one side of the top of the mounting bracket 5 by bolts. The output shaft of the drive motor 6 extends into the mounting bracket 5 and is fixedly mounted with a driving gear 22 by key connection. A toothed disc 4 is fixedly sleeved on the slide rail 3 by welding, and the driving gear 22 is engaged with the toothed disc 4. When the position of the trolley mechanism needs to be adjusted, the drive motor 6 is started, and the drive motor 6 drives the driving gear 22 to rotate. Since the driving gear 22 is engaged with the toothed disc 4, the slide rail 3 can be driven to rotate at this time, so that the position of the raised trolley mechanism can be rotated so that the trolley mechanism can be received at the required position.

[0063] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive motor 6, stepper motor 11, weight sensor 19, electric push rod 20 and servo motor 25 are commonplace, and are all conventional means or common knowledge, so they will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0064] The drawings in this application are for illustrative purposes only. The sizes and shapes of the components shown are not intended to be limiting, but are merely for illustrative purposes. In actual implementation, the components may be appropriately configured and adjusted based on specific needs and actual conditions.

[0065] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
