Description

Technical Field

[0001] This invention relates to the field of material conveying technology, and in particular to an adaptive conveying device for dumbbell production. Background Technology

[0002] Dumbbells are classic strength training tools, their core function being to improve muscle strength through resistance training. Their production is based on metalworking, combining different material processing techniques. In the production process, raw materials are first melted into molten iron or rolled into metal rods to prepare for subsequent shaping. Then, natural rubber, synthetic rubber, or PVC material is used to wrap the outer layer around the metal core.

[0003] To improve dumbbell production efficiency, dumbbells need to be transported between different devices. However, to ensure the stability of the dumbbell placement, a limit mechanism needs to be installed on the existing conveying equipment. This is not only troublesome, but also requires stopping the entire conveying mechanism, which seriously affects processing efficiency. At the same time, to ensure the quality of the dumbbells, an additional inspection process is required, which consumes a lot of manpower and costs, and the inspection efficiency is not high. Summary of the Invention

[0004] The technical problem to be solved by this invention is that in order to ensure the stability of dumbbell placement, a limiting mechanism needs to be set on the existing conveying equipment. This is not only troublesome, but also requires stopping the entire conveying mechanism, which seriously affects the processing efficiency. At the same time, in order to ensure the quality of dumbbells, an additional inspection process is required, which consumes a lot of manpower and costs, and the inspection efficiency is not high.

[0005] The technical solution adopted by the present invention to solve its technical problem is: an adaptive conveying device for dumbbell production and processing, including a horizontal main frame, a combined conveying module installed on the upper surface of the horizontal main frame, and a plurality of detachable external adapter seats installed on the outer surface of the combined conveying module.

[0006] An electrically controlled rotating adjustment arm is installed on the upper surface of the horizontal main frame, and an optical detection module is installed on the electrically controlled rotating adjustment arm.

[0009] The second horizontal frame has a threaded translation block protruding into the embedded translation guide rail on its inner side. An electrically controlled translation screw that cooperates with the threaded translation block is installed inside the embedded translation guide rail.

[0010] The combined conveyor module includes a first conveyor belt and a second conveyor belt mounted on a first horizontal frame, and a third conveyor belt and a fourth conveyor belt mounted on a second horizontal frame. The first conveyor belt and the second conveyor belt are horizontally arranged together, and the third conveyor belt and the fourth conveyor belt are horizontally arranged together.

[0011] The detachable external adapter is fixedly installed on the lateral connectors on the outer surfaces of the first, second, third, and fourth conveyor belts, the detachable adapter is slidably fitted on the outside of the lateral connector, and the elastic limiting buckle is elastically fitted on the lateral connector.

[0012] A pressure control module is installed on the side wall of the lateral connector.

[0013] The electrically controlled flipping guide rail includes a flipping guide rail hinged to the upper surface of the central mounting base, an adjusting support rod for controlling the flipping guide rail, and an upper buffer spring elastically mounted on the upper surface of the flipping guide rail.

[0014] The electrically controlled rotating adjustment arm includes lateral translation guide rails fixed on the outer walls of both sides of the horizontal main frame, an external mounting base installed on the outside of the lateral translation guide rails, a transverse adjustment tube installed at the end of the external mounting base, an end assembly base fixed at the end of the transverse adjustment tube, an arc-shaped detection base fixed inside the end assembly base, an optical scanning probe fixed on the arc-shaped detection base, and a rotation adjustment module installed inside the end assembly base.

[0015] The beneficial effects of this invention are: (1) An adaptive conveying device for dumbbell production and processing of the present invention adopts a horizontally arranged combined conveying module and changes the position of its upper detachable external adapter seat by reverse translation, thereby limiting the two sides of the dumbbell, greatly improving the stability of dumbbell conveying, and eliminating the need for machine downtime maintenance.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The adaptive conveying device shown is used in dumbbell production and processing. It includes a horizontal main frame 1, a combined conveying module 2 is installed on the upper surface of the horizontal main frame 1, and a plurality of detachable external adapter seats 3 are installed on the outer surface of the combined conveying module 2.

[0025] An electrically controlled rotating adjustment arm 4 is installed on the upper surface of the horizontal main frame 1, and an optical detection module 5 is installed on the electrically controlled rotating adjustment arm 4.

[0026] To facilitate adjustment, the horizontal main unit frame 1 includes a first horizontal frame 101, a second horizontal frame 102, and a centrally located control base 103.

[0027] To facilitate separation, the central control base 103 includes a central mounting base 1031 disposed between the first horizontal frame 101 and the second horizontal frame 102, embedded translation guide rails 1032 mounted on the lower ends of both sides of the central mounting base 1031, and electrically controlled flip guide rails 1033 mounted on the upper surface of the central mounting base 1031.

[0028] To facilitate the translational movement and adjust the gap between the first horizontal frame 101 and the second horizontal frame 102, the inner side of the second horizontal frame 102 has a threaded translation block 1021 protruding into the embedded translation guide 1032. The embedded translation guide 1032 is equipped with an electrically controlled translation screw 10321 that cooperates with the threaded translation block 1021.

[0029] To facilitate electrically controlled conveying, the combined conveying module 2 includes a first conveyor belt 21 and a second conveyor belt 22 mounted on a first horizontal frame 101, and a third conveyor belt 23 and a fourth conveyor belt 24 mounted on a second horizontal frame 102. The first conveyor belt 21 and the second conveyor belt 22 are horizontally arranged, and the third conveyor belt 23 and the fourth conveyor belt 24 are horizontally arranged.

[0030] The first conveyor belt 21, the second conveyor belt 22, the third conveyor belt 23, and the fourth conveyor belt 24 are all designed to operate independently. When the first dumbbell is placed on the combined conveyor module 2, the first conveyor belt 21 and the third conveyor belt 23 move, while the second conveyor belt 22 and the fourth conveyor belt 24 remain stationary. At this time, the detachable external adapter seats 3 on the first conveyor belt 21, the second conveyor belt 22, the third conveyor belt 23, and the fourth conveyor belt 24 will move in the opposite direction and clamp onto both sides of the dumbbell. After the first adapter is installed, subsequent dumbbells can be placed directly upwards.

[0031] To facilitate the electronically controlled material guiding, a detachable external adapter 3 is fixedly installed on the lateral connector 31 on the outer surface of the first conveyor belt 21, the second conveyor belt 22, the third conveyor belt 23 and the fourth conveyor belt 24, a detachable adapter 32 is slidably fitted on the outside of the lateral connector 31, and an elastic limiting buckle 33 is elastically fitted on the lateral connector 31.

[0032] The elastic limiting buckle 33 is retracted into the side connector 31 by external compression, thereby separating it from the detachable adapter 32. The detachable adapter 32 can then be quickly slid laterally along the side connector 31 to separate and disassemble.

[0033] To facilitate pressure monitoring, a pressure control module 34 is installed on the side wall of the lateral connector 31.

[0034] The pressure control module 34 monitors the pressure when the detachable adapter 32 is pressed against the outside of the dumbbell. When the pressure reaches a certain value, it controls the second conveyor belt 22 to move synchronously with the first conveyor belt 21 and the fourth conveyor belt 24 with the third conveyor belt 23.

[0035] To facilitate the flipping guide, the electrically controlled flipping guide 1033 includes a flipping guide 10331 mounted on the upper surface of the central mounting base 1031, an adjusting support rod 10332 for controlling the flipping guide 10331, and an upper buffer spring 10333 elastically mounted on the upper surface of the flipping guide 10331.

[0036] The adjusting strut 10332 extends and retracts to adjust the angle of the flip guide rail 10331, and then uses the upper buffer spring 10333 at its upper end for buffering.

[0037] To facilitate the tilting adjustment, the electrically controlled rotating adjustment arm 4 includes a lateral translation guide rail 41 fixed on the outer walls of both sides of the horizontal main frame 1, an external mounting base 42 installed on the outside of the lateral translation guide rail 41, a transverse adjustment tube 43 installed at the end of the external mounting base 42, an end mounting base 44 fixed at the end of the transverse adjustment tube 43, an arc-shaped detection base 45 fixed inside the end mounting base 44, an optical scanning probe 46 fixed on the arc-shaped detection base 45, and a rotation adjustment module 47 installed inside the end mounting base 44.

[0038] The external mounting base 42 is slidably mounted on the outside of the lateral translation guide rail 41, allowing it to slide and translate along the rail. When the dumbbell reaches the detection position, the external mounting base 42 translates along the lateral translation guide rail 41 towards the horizontal main frame 1, causing the arc-shaped detection seat 45 on the transverse adjustment frame 43 to translate to the outside of the dumbbell. Then, the end mounting base 44 causes the arc-shaped detection seat 45 to flip, causing the optical scanning probe 46 to face the dumbbell. Through multi-angle scanning, the external structure of the dumbbell is determined to meet the detection requirements. The function of the rotation adjustment module 47 is to move the arc-shaped detection seat 45.

[0039] Operating principle of the device 1. Adaptive conveying limit principle Core drive: The combined conveyor module 2 consists of independently operating first conveyor belt 21, second conveyor belt 22 (installed on the first horizontal frame 101), third conveyor belt 23, and fourth conveyor belt 24 (installed on the second horizontal frame 102). The spacing can be adjusted by reverse translation to accommodate dumbbells of different sizes.

[0040] Limit adjustment: The detachable external adapter 3 is fixed to each conveyor belt via the lateral connector 31. When the dumbbell is placed on the combined conveyor module 2, the second conveyor belt 22 moves in the opposite direction with the first conveyor belt 21 and the fourth conveyor belt 24 moves in the opposite direction with the third conveyor belt 23, causing the detachable external adapter 3 to move closer to both sides of the dumbbell. The pressure control module 34 on the lateral connector 31 monitors the contact pressure between the detachable adapter 32 and the dumbbell in real time. After reaching the set value, it controls the conveyor belt to run synchronously, realizing stable clamping and limiting of the dumbbell without stopping the machine for adjustment.

[0041] Adapter removal: When the adapter needs to be replaced, squeeze the elastic limit buckle 33 to retract it into the side connector 31, and then slide along the side connector 31 to remove the detachable adapter 32, quickly adapting to dumbbells of different sizes.

[0042] 2. Multi-angle optical detection principle Position adjustment: The external mounting base 42 of the electrically controlled rotating adjustment arm 4 can slide along the lateral translation guide rails 41 on both sides of the horizontal main frame 1, driving the lateral adjustment tube 43 and the end mounting base 44 to move closer to or further away from the dumbbell; the lateral adjustment tube 43 can extend and retract to adjust the lateral position of the end mounting base 44, ensuring that the arc-shaped detection seat 45 is accurately aligned with the dumbbell.

[0043] Angle adjustment: The rotation adjustment module 47 inside the end mounting base 44 can drive the arc-shaped detection base 45 to flip, so that the optical scanning probe 46 on the arc-shaped detection base 45 is turned towards the dumbbell; through the combination of "sliding translation + telescopic adjustment + flip adjustment", the optical scanning probe 46 can cover multiple angles on the outside of the dumbbell, realize all-round structural detection, and improve detection efficiency and accuracy.

[0044] 3. Principle of rapid separation of non-conforming products Spacing adjustment: The embedded translation guide rail 1032 of the central control base 103 contains an electrically controlled translation screw 10321, which cooperates with the internal thread translation block 1021 of the second horizontal frame 102; when a defective dumbbell is detected, the electrically controlled translation screw 10321 rotates, driving the internal thread translation block 1021 to move, widening the gap between the first horizontal frame 101 and the second horizontal frame 102, forming a defective product separation channel.

[0045] Material guiding assistance: The electrically controlled tilting guide rail 1033 on the central mounting base 1031 controls the angle of the tilting guide rail 10331 by adjusting the support rod 10332. When the defective dumbbells arrive at the separation channel with the conveyor belt, the tilting guide rail 10331 tilts upward, and with the upper buffer spring 10333 (to avoid collision damage to the dumbbells), the defective products are guided away from the conveying path, achieving rapid separation without affecting the normal conveying process.

[0046] Device operation process 1. Preparations before powering on Component inspection: Confirm that the horizontal main frame 1 (including the first horizontal frame 101, the second horizontal frame 102, and the central control base 103) is securely connected, and that the power supply to each conveyor belt of the combined conveyor module 2 (first conveyor belt 21, second conveyor belt 22, third conveyor belt 23, and fourth conveyor belt 24), the electrically controlled rotating adjustment arm 4, and the optical detection module 5 is normal; check whether the detachable external adapter 3 (including the side connector 31, the detachable adapter 32, and the elastic limit buckle 33) is securely installed and whether the elastic limit buckle 33 has been reset.

[0047] Initial adjustment: The distance between the first horizontal frame 101 and the second horizontal frame 102 is adjusted to the minimum (conveying state) by using the electrically controlled translation screw 10321; the external mounting base 42 of the electrically controlled rotating adjustment arm 4 is moved along the lateral translation guide rail 41 to the initial position away from the conveying path, and the optical scanning probe 46 is in standby state; the adjusting support rod 10332 of the electrically controlled flipping guide rail 1033 is adjusted to keep the flipping guide rail 10331 horizontal (flush with the conveyor belt).

[0048] 2. Adaptive conveying and limiting First dumbbell adapter: Place the first dumbbell in the middle of the combined conveyor module 2 (between the first conveyor belt 21 / second conveyor belt 22 and the third conveyor belt 23 / fourth conveyor belt 24), and start the combined conveyor module 2; the first conveyor belt 21 and the third conveyor belt 23 run in the forward direction, and the second conveyor belt 22 and the fourth conveyor belt 24 run in the reverse direction, driving the detachable external adapter 3 to move closer to both sides of the dumbbell.

[0049] Pressure-triggered synchronization: When the pressure control module 34 of the lateral connector 31 detects that the contact pressure between the detachable adapter 32 and the dumbbell reaches the set value, it automatically controls the second conveyor belt 22 to synchronize with the first conveyor belt 21 and the fourth conveyor belt 24 to synchronize with the third conveyor belt 23. The detachable external adapter 3 stably clamps the dumbbell and transports it to the detection area with the conveyor belt.

[0050] Subsequent dumbbell delivery: After the first dumbbell is adapted, subsequent dumbbells can be placed directly and continuously on the combined delivery module 2. The detachable external adapter 3 will automatically align and clamp according to the limit parameters of the previous dumbbell, achieving uninterrupted adaptive delivery.

[0051] 3. Multi-angle optical inspection Detection position alignment: When the dumbbell reaches the detection area, the electrically controlled rotating adjustment arm 4 is activated, the external mounting base 42 slides along the lateral translation guide rail 41 toward the dumbbell side, and the lateral adjustment tube 43 extends and retracts to adjust the position of the end mounting base 44, so that the arc-shaped detection base 45 is fitted onto the outside of the dumbbell.

[0052] Multi-angle scanning: The rotation adjustment module 47 drives the arc-shaped detection seat 45 to flip, which in turn drives the optical scanning probe 46 to rotate around the outside of the dumbbell, performing an all-round optical scan of the dumbbell's surface and structural dimensions; the scan data is transmitted to the control system in real time to determine whether the dumbbell is qualified.

[0053] Post-detection reset: After detection, the external mounting base 42 returns to its initial position along the lateral translation guide rail 41, the arc-shaped detection base 45 flips and resets, and the optical scanning probe 46 switches to standby mode, waiting for the next dumbbell to enter the detection area.

[0054] 4. Separation and handling of non-conforming products Separation channel opening: If the control system determines that the dumbbell is unqualified, the electric translation screw 10321 will start immediately, driving the second horizontal frame 102 to move away from the first horizontal frame 101 along the embedded translation guide rail 1032, increasing the distance between the two frames and forming a separation channel for unqualified products.

[0055] Defective product removal: When the defective dumbbell arrives at the separation channel with the conveyor belt, the adjusting support rod 10332 of the electrically controlled flipping guide rail 1033 extends, pushing the flipping guide rail 10331 to flip upward; after the upper buffer spring 10333 on the flipping guide rail 10331 contacts the dumbbell, it guides the dumbbell away from the conveying path along the flipping guide rail 10331 and falls into the defective product collection area.

[0056] Restoring the conveying state: After the defective product is removed, the electrically controlled translation screw 10321 rotates in the opposite direction, pulling the second horizontal frame 102 back to its initial position. The distance between the first horizontal frame 101 and the second horizontal frame 102 is restored to its minimum, and the device continues normal conveying and testing.

[0057] 5. Shutdown and Storage Stop conveying: After all dumbbell processing and conveying is completed, close the combined conveyor module 2 and stop the operation of each conveyor belt (first conveyor belt 21, second conveyor belt 22, third conveyor belt 23, and fourth conveyor belt 24).

[0058] Component reset: The external mounting base 42 of the electrically controlled rotating adjusting arm 4 is retracted to its initial position along the lateral translation guide rail 41, the arc-shaped detection seat 45 is flipped and reset, and the optical scanning probe 46 is de-energized; the adjusting support rod 10332 of the electrically controlled flipping guide rail 1033 is adjusted so that the flipping guide rail 10331 is restored to horizontal; the distance between the first horizontal frame 101 and the second horizontal frame 102 is adjusted to the minimum through the electrically controlled translation screw 10321 to reduce the space occupied by the equipment.

[0059] Maintenance and inspection: Check whether the detachable external adapter 3, side connector 31, and pressure control module 34 are intact, and clean the surface impurities of the combined conveyor module 2; if the adapter needs to be replaced, follow the procedure of "squeeze the elastic limit buckle 33 → remove the detachable adapter 32 → install the new adapter → reset the elastic limit buckle 33" to complete the shutdown and storage.
