Description

Technical Field

[0001] The utility model belongs to the technical field of gravity blockers, and in particular relates to a linear gravity blocker. Background Art

[0002] Linear gravity blockers play a vital role in industrial environments. Their core function is to stop or slow down the movement of the wire. In production lines, logistics transportation systems or similar high-intensity working environments, due to various reasons such as equipment failure, operating errors or external interference, the wire may suddenly lose control and fall or move at an extremely fast speed. In this case, the linear gravity blocker can intervene quickly and accurately, and effectively stop or slow down the speed of the wire through its internal mechanism, thereby preventing possible serious accidents.

[0003] After traditional blockers block the line pallet, there is a hidden danger that the line pallet will retreat due to inertia. This retreat may not only cause secondary damage to the equipment, but also threaten the safety of the operator. For example, on a high-speed conveyor belt, if the pallet suddenly retreats due to inertia, it may cause items to scatter, equipment damage, or even casualties. Utility Model Content

[0004] The utility model provides a wire gravity blocker, aiming to solve the hidden danger that after the traditional blocker blocks the wire body tray, the wire body tray is affected by inertia and causes the wire body tray to retreat, which may not only cause secondary damage to the equipment, but also threaten the safety of the operator.

[0005] The utility model is implemented as follows: a linear gravity blocker comprises an assembly seat; a rotating shaft rotating on the inner side of the assembly seat; a same blocking plate is arranged between two of the rotating shafts; a buffer mechanism is arranged on the outer side of the blocking plate; wherein the buffer mechanism comprises: a connecting rod arranged on the outer side of the blocking plate; a side baffle is arranged on the side of the connecting rod away from the blocking plate; a plurality of return springs arranged on the other side of the side baffle, and dampers are arranged in the plurality of return springs; a buffer plate arranged on the other side of the plurality of return springs, and a flexible pad is arranged on the outer side of the buffer plate.

[0006] Preferably, a hydraulic cylinder is provided at the lower position of the assembly seat, a wedge block is rotatably matched with the side of the blocking plate opposite to the hydraulic cylinder, and the output end of the hydraulic cylinder is connected to the outer side wall of the blocking plate.

[0007] Preferably, a shock-absorbing pad is provided on the bottom side of the assembly seat, and an assembly hole is formed through the shock-absorbing pad.

DETAILED DESCRIPTION

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model embodiment provides a linear gravity blocker, such as Figure 1-5 As shown, it includes an assembly seat 1; a rotating shaft 2 rotating on the inner side of the assembly seat 1; a same blocking plate 3 is arranged between the two rotating shafts 2; a buffer mechanism is arranged on the outer side of the blocking plate 3; wherein the buffer mechanism includes: a connecting rod 401 arranged on the outer side of the blocking plate 3; a side baffle 402 is arranged on the side of the connecting rod 401 away from the blocking plate 3; a plurality of return springs 403 are arranged on the other side of the side baffle 402, and dampers are arranged in the plurality of return springs 403; a buffer plate 404 is arranged on the other side of the plurality of return springs 403, and a flexible pad 405 is arranged on the outer side of the buffer plate 404.

[0023] It should be noted that after blocking the wire pallet, the traditional blocker may cause the wire pallet to retreat due to inertia. This retreat may not only cause secondary damage to the equipment, but also threaten the safety of the operator. This solution allows the wire pallet to move at an appropriate speed, thereby accurately controlling the blocking and releasing actions, preventing accidents from occurring during the retreat of the wire pallet, ensuring the accuracy and stability of the transmission process, and reducing the risks caused by excessive speed; when the wire pallet contacts the blocker, the buffer mechanism not only slows down the speed of the wire pallet, but also reduces the impact force during the collision, ensuring that it can stop smoothly after the collision. This design effectively protects the wire pallet and other equipment on the production line and extends its service life.

[0024] Specifically, in this embodiment, the scheme mainly includes an assembly seat 1; a rotating shaft 2 rotating inside the assembly seat 1; a same blocking plate 3 is arranged between the two rotating shafts 2; a buffer mechanism is arranged outside the blocking plate 3; on the production line, in order to ensure that the line body pallet travels at a suitable speed and prevent accidents caused by excessive speed, a number of blockers are usually arranged; these blockers can not only provide timely blocking when the speed of the line body pallet is too fast, but also reduce the impact force and damage of the line body pallet through a specific mechanism;

[0025] When the wire pallet moves toward the blocker at an excessively fast speed, the blocking plate 3 in the rear blocker will first rotate downward to allow the wire pallet to pass through; this design allows the production line to have a certain degree of flexibility when needed, ensuring that the wire pallet can continue to move forward; however, when the front blocker contacts the fast-moving wire pallet, the blocking plate 3 blocks it, causing the wire pallet to be blocked and move backward;

[0026] At this time, the blocking plate 3 in the rear blocker will quickly rotate to the blocking state, ready to receive the impact of the wire tray; when the rear blocking plate 3 contacts the wire tray, the buffer mechanism begins to play its key role; the wire tray contacts the side baffle 402 in the rear blocker, and the return spring 403 is quickly compressed, and the built-in damper starts to work;

[0027] The main purpose of the damper is to increase the damping effect of the spring, so that the return spring 403 generates greater resistance when it is compressed and released; this resistance can further slow down the speed and impact force of the wire tray, thereby protecting the wire and other equipment on the production line from damage; the combination of the return spring 403 and the damper enables the wire tray to quickly slow down after impact, reducing possible damage;

[0028] At the same time, the buffer plate 404 provides further support and buffering for the wire tray on the other side of the return spring 403; and the flexible pad 405 on the outside of the buffer plate 404 directly contacts the wire tray, and its soft material can reduce the damage of the wire tray during collision and ensure that the wire tray can stop smoothly;

[0029] Through this series of mechanisms, the blockers on the production line can not only effectively control the speed of the line pallet, but also provide necessary buffering and support when necessary to protect the production line and line pallet from potential damage; this design not only improves the safety of the production line, but also ensures the continuity and efficiency of the production process.

[0030] In a further preferred embodiment of the present invention, Figure 3-4As shown, a hydraulic cylinder 5 is provided at the lower position of the assembly seat 1 , a wedge block 11 is rotatably fitted on the side of the blocking plate 3 opposite to the hydraulic cylinder 5 , and the output end of the hydraulic cylinder 5 is connected to the outer side wall of the blocking plate 3 .

[0031] In this embodiment, when the telescopic end of the hydraulic cylinder 5 is extended, it pushes the blocking plate 3 to rotate downward to allow the wire tray to pass; when the telescopic end is retracted, the blocking plate 3 rotates upward to restore the blocking state. This design makes the rotation of the blocking plate 3 more stable and controllable, and the rotation angle of the blocking plate 3 can be controlled by adjusting the telescopic length of the hydraulic cylinder 5, thereby adapting to wire trays of different speeds and weights.

[0032] In a further preferred embodiment of the present invention, Figure 1 As shown, a shock-absorbing pad 9 is provided on the bottom side of the assembly seat 1 , and an assembly hole 10 is formed through the shock-absorbing pad 9 .

[0033] In this embodiment, the shock-absorbing pad 9 can effectively reduce the vibration and noise generated by the equipment during operation, and can also improve the stability and durability of the blocker. The assembly hole 10 on the shock-absorbing pad 9 is used to fix the assembly seat 1 at an appropriate position on the production line, which not only ensures the stability and accuracy of the assembly seat 1, but also facilitates subsequent maintenance and replacement.

[0034] In a further preferred embodiment of the present invention, Figure 3-4 As shown, the inner side wall at the lower position of the assembly seat 1 is rotatably matched with a blocking roller 6.

[0035] In this embodiment, when the blocking plate 3 is impacted by the wire tray and starts to rotate, the blocking roller 6 serves as a limiting device to prevent the blocking plate 3 from excessively rotating.

[0036] In a further preferred embodiment of the present invention, Figure 1 As shown, a displacement sensor 7 and a controller 8 are disposed on the outer side of the assembly seat 1 , and the controller 8 is electrically connected to the displacement sensor 7 and the hydraulic cylinder 5 .

[0037] In this embodiment, when the wire tray hits the blocking plate 3, the blocking plate 3 will be displaced to a certain extent. The displacement sensor 7 can accurately capture this displacement and transmit the data in the form of an electrical signal to the controller 8 for processing; and the controller 8 can control the extension and contraction of the hydraulic cylinder 5 through the electrical signal, thereby adjusting the position and angle of the blocking plate 3, and realizing accurate control of the blocking of the wire tray.

[0038] In a further preferred embodiment of the present invention, Figure 2 As shown, the outer surface of the flexible pad 405 is provided with anti-slip textures.

[0039] In this embodiment, the anti-slip texture can effectively increase the contact area and provide an additional friction coefficient, so that the wire is not easy to slide when subjected to external force. At the same time, the anti-slip texture can also provide a certain degree of gripping force, so that the wire is more firmly fixed on the flexible pad 405.

[0040] Working principle: On the production line, in order to ensure that the line pallet moves at an appropriate speed and prevent accidents caused by excessive speed, several blockers are usually set; these blockers can not only provide timely blocking when the line pallet speed is too fast, but also reduce the impact force and damage of the line pallet through specific mechanisms;

[0041] When the wire tray moves toward the blocker at an excessively fast speed, the blocking plate 3 in the rear blocker rotates downward under the drive of the hydraulic cylinder 5 to allow the wire tray to pass; when the telescopic end retracts, the blocking plate 3 rotates upward to restore the blocking state. This design makes the rotation of the blocking plate 3 more stable and controllable, and the rotation angle of the blocking plate 3 can be controlled by adjusting the telescopic length of the hydraulic cylinder 5, thereby adapting to wire trays of different speeds and weights;

[0042] This design allows the production line to have a certain degree of flexibility when needed, ensuring that the line body pallet can continue to move forward; however, when the blocker on the front side contacts the fast-moving line body pallet, the blocking plate 3 blocks it, causing the line body pallet to be blocked and retreat;

[0043] At this time, the blocking plate 3 in the rear blocker will quickly rotate to the blocking state, ready to receive the impact of the wire tray; when the rear blocking plate 3 contacts the wire tray, the buffer mechanism begins to play its key role; the wire tray contacts the side baffle 402 in the rear blocker, and the return spring 403 is quickly compressed, and the built-in damper starts to work;

[0044] The main purpose of the damper is to increase the damping effect of the spring, so that the return spring 403 generates greater resistance when it is compressed and released; this resistance can further slow down the speed and impact force of the wire tray, thereby protecting the wire and other equipment on the production line from damage; the combination of the return spring 403 and the damper enables the wire tray to quickly slow down after impact, reducing possible damage;

[0045] At the same time, the buffer plate 404 provides further support and buffering for the wire tray on the other side of the return spring 403; and the flexible pad 405 on the outside of the buffer plate 404 directly contacts the wire tray, and its soft material can reduce the damage of the wire tray during collision and ensure that the wire tray can stop smoothly;

[0046] Through this series of mechanisms, the blockers on the production line can not only effectively control the speed of the line pallet, but also provide necessary buffering and support when necessary to protect the production line and line pallet from potential damage; this design not only improves the safety of the production line, but also ensures the continuity and efficiency of the production process.
