Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically to an electrostatic eliminator installation mechanism suitable for dual-drive conveyor belts. Background Technology

[0002] Conveyor belts generate significant static electricity during operation due to friction with the drive pulley, materials, or themselves. This is especially true when transporting non-conductive materials (such as plastics or dust) or in dry environments, where the static voltage can reach thousands to tens of thousands of volts. Static eliminators neutralize the static charge on the belt surface by releasing positive and negative ions through ionization of the air, preventing the charge from accumulating to dangerous levels.

[0003] Generally, static eliminators are installed at the drive end of a belt conveyor (near the drive pulley) or at the material loading point, because these areas experience high friction and are the primary locations for static electricity generation. For example, static eliminators are installed at the initial point of contact between the belt and the drive pulley or at the point of impact when material falls. When the static eliminator is installed at the initial point of contact between the belt and the drive pulley, it is typically mounted using fixing bolts.

[0004] For certain film conveying scenarios, a dual-drive conveyor belt system is required. This system includes two sets of rollers, one of which is in use while the other is on standby. If one roller fails, the other can immediately take over, ensuring continuous film conveying. If a single set of static eliminators is installed in this system using fixing bolts, it needs to be moved to the vicinity of the other roller after roller switching. This process requires frequent loosening and tightening of the bolts, making the operation complex. If two sets of static eliminators are installed in this system using fixing bolts, it not only increases production costs for the company, but the static eliminator located on standby may also suffer damage due to prolonged inactivity, even with regular maintenance.

[0005] To address this issue, we propose an electrostatic eliminator installation mechanism suitable for dual-drive conveyor belts. Utility Model Content

[0006] The purpose of this utility model is to solve the problems in the prior art by proposing an electrostatic eliminator installation mechanism suitable for dual-drive conveyor belts. This installation mechanism achieves convenient switching between the electrostatic eliminator and the two sets of receiving cavities corresponding to the two sets of rollers, making it easy to use.

[0007] To solve the above problems, this utility model provides the following technical solution:

[0008] An electrostatic eliminator mounting mechanism suitable for dual-drive conveyor belts includes a frame for mounting two rollers in a dual-drive system. The frame has accommodating cavities on the periphery of both rollers, and one of the accommodating cavities is provided with a bracket for mounting the electrostatic eliminator. The frame has a slide for connecting the two accommodating cavities, so that the bracket can switch positions between the two accommodating cavities through the slide.

[0009] As a further embodiment of this utility model, the installation mechanism also includes a limiting member disposed on the frame and used to limit the support in the accommodating cavity.

[0010] As a further embodiment of this utility model: the limiting member includes a fixed block, a moving block, and an elastic member for connecting the two. The fixed block is fixedly mounted on the frame, and the elastic member is used to make the moving block have a tendency to move toward the receiving cavity, so that the moving block and the support are in a contact state, thereby limiting the position of the support.

[0011] As a further embodiment of this utility model: the moving block is provided with a connecting rod arranged along the deformation direction of the elastic element, and the connecting rod is located inside the elastic element. The moving block can move away from the support as the connecting rod moves to release the position limitation on the support.

[0012] As a further embodiment of this utility model, the mounting mechanism also includes a locking element, which locks the position of the connecting rod when the moving block is separated from the bracket.

[0013] As a further embodiment of this utility model: the locking component includes a plug on the connecting rod and two sets of spring plungers on the frame. The plug consists of a cylindrical part and a frustum part arranged coaxially with the cylindrical part. One end of the cylindrical part is located on the connecting rod and forms a step. The two sets of spring plungers are arranged opposite to each other and form an adjustable clamping area between them. The clamping area is located below the frustum part so that when the frustum part moves downward, the two spring plungers can slide on the side of the frustum part until they abut against the step.

[0014] As a further embodiment of this utility model: two sets of through slots are provided on the sides of the cylindrical part and the frustum part, and the two sets of through slots are arranged opposite to each other. One end of the cylindrical part is rotated on the connecting rod so that the plane where the two through slots are located can be adjusted to be coplanar with the plane where the two spring plungers are located as the cylindrical part rotates.

[0015] As a further embodiment of this utility model, the accommodating cavity is generally circular in shape.

[0016] As a further embodiment of this utility model: the elastic element is a return spring, and the two ends of the return spring are fixedly connected to the fixed block and the moving block, respectively.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This mechanism enables flexible switching of the static eliminator between the two rollers by setting accommodating slots and configuring slides on both sides of the frame. The position adjustment of the static eliminator can be completed without stopping the machine, which significantly improves the equipment maintenance efficiency and operational continuity.

[0019] 2. The added limiting component effectively fixes the position of the bracket through a mechanical limiting mechanism, which solves the problem of displacement deviation that may occur when the static eliminator is placed in the accommodating cavity. Its dynamic adjustment characteristics can adapt to the roller vibration environment, ensuring that the static eliminator maintains the appropriate distance from the belt, thereby maintaining a stable elimination effect and reducing the risk of mechanical wear.

[0020] 3. An elastic limiting scheme combining a fixed block and a moving block is adopted, which utilizes the preload of the elastic element to achieve adaptive clamping. This design simplifies the adjustment process while ensuring limiting accuracy. The elastic element can absorb impact loads, avoid component fatigue caused by rigid limiting, and significantly extend the service life of the mechanism.

[0021] 4. By integrating the connecting rod inside the elastic element, the limit release can be completed with one hand. This concealed connecting rod design maintains the compactness of the structure and avoids lateral force interference through axial movement. Combined with the elastic reset characteristic, it makes the operation more effortless.

[0022] 5. The combination of the spring plunger and the stepped insert forms an adaptive locking system. The combination design of the stepped cylindrical part and the conical surface of the frustum ensures that the spring plunger can lock the insert when it descends to the designated position.

[0023] 6. The innovative combination of insert block, through slot and rotation design allows the plane of the two through slots to be dynamically matched with the plane of the two spring plungers. By rotating and adjusting, the two planes can be arranged in a coplanar or non-coplanar manner. When the two planes are in a coplanar manner, the insert block can be easily unlocked.

[0024] 7. The circular cross-section cavity design enhances the structural load-bearing capacity through uniform stress distribution. Compared with rectangular structures, it reduces stress concentration. At the same time, the arc-shaped inner wall facilitates the sliding adjustment of the support, and the rounded corner transition design reduces the risk of foreign object jamming and improves the environmental adaptability of the equipment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1-4 As shown, an electrostatic eliminator mounting mechanism suitable for dual-drive conveyor belts includes a dual-drive system. The dual-drive system includes a frame 1, on which two sets of rollers a are rotatably mounted. A conveyor belt is fitted between the two rollers a. The two sets of rollers a can be selectively driven by the same drive motor, or they can be driven by two separate drive motors. In use, one set of rollers a operates while the other serves as a backup. When the operating roller a fails, the backup roller a can be immediately put into use.

[0033] Under the aforementioned dual-drive design, this application only installs one set of static eliminators on frame 1. By adjusting the position of the static eliminators, the switching adjustment of the static eliminators at the circumferential positions of the two rollers a is achieved. The specific design is as follows:

[0034] On the frame 1, accommodating cavities 2 are formed on the circumference of both rollers a. One of the accommodating cavities 2 is fitted with a bracket 3 for mounting the static eliminator. A slide 4 is formed on the frame 1 to connect the two accommodating cavities 2. Preferably, the accommodating cavities 2 are arranged in a circular shape to accommodate the cylindrical bracket 3. Figure 1As shown, a bracket 3 is inserted into the right-side receiving cavity 2. When the right-side roller a corresponding to the static eliminator on this side fails and cannot work, another spare left-side roller a can be started to work. At the same time, the bracket 3 is slid from the right-side receiving cavity 2 into the slide rail 4 until it slides into the left-side receiving cavity 2, realizing the quick switching of the static eliminator on the frame 1. This switching method does not require disassembling and reinstalling the bracket 3, but can be directly slid in the two receiving cavities 2 and the slide rail 4, which is convenient to use.

[0035] like Figures 1-2 As shown, to ensure the stability of the bracket 3 within the receiving cavity 2, this application provides a limiting member 5 on the frame 1. The limiting member 5 is used to lock the position of the end of the bracket 3 placed in the receiving cavity 2, so that the bracket 3 is stably placed within the receiving cavity 2, thus ensuring the stable installation of the static eliminator. The limiting member 5 includes a fixed block 501, a movable block 502, and an elastic member 503 for connecting the two. The fixed block 501 is fixedly mounted on the frame 1. Both the fixed block 501 and the movable block 502 are located below the receiving cavity 2. The elastic member 503 is used to give the movable block 502 a tendency to move towards the receiving cavity 2. That is, when the bracket 3 is inserted into the receiving cavity 2, under the elastic action of the elastic member 503, the movable block 502 can abut against the bracket 3 until the bracket 3 is limited within the receiving cavity 2. At this time, the position of the bracket 3 remains stable, and the elastic member 503 is in a compressed state.

[0036] When it is necessary to slide the bracket 3 from the receiving cavity 2 into the slide rail 4, the moving block 502 can be driven downwards until the contact between the moving block 502 and the bracket 3 is released. At this time, the bracket 3 is in a free state in the receiving cavity 2 and can be manually driven to slide into the slide rail 4. Preferably, the elastic element 503 can be selected as a return spring, and the two ends of the return spring are fixedly connected to the fixed block 501 and the moving block 502 respectively.

[0037] To facilitate downward movement of the movable block 502 by the operator, a connecting rod 6 is provided on the movable block 502. The connecting rod 6 is arranged along the deformation direction of the elastic element 503, and is located inside the elastic element 503. Figure 2 As can be seen, the connecting rod 6 is arranged along the vertical direction. At this time, pulling the connecting rod 6 downward will drive the moving block 502 to move downward, thereby realizing the downward adjustment of the position of the moving block 502.

[0038] In order to lock the link 6 after it descends to the designated position, this application provides a locking device to lock the position of the link 6 when the moving block 502 is separated from the bracket 3. Specifically, the locking mechanism includes a plug 8 mounted on the connecting rod 6. The plug 8 consists of a cylindrical portion 801 and a frustum portion 802 coaxially arranged with the cylindrical portion 801. One end of the cylindrical portion 801 is mounted on the connecting rod 6, and this end forms a step 9. The locking mechanism also includes two sets of telescopic members mounted on the frame 1. The two sets of telescopic members are arranged opposite each other, and an adjustable clamping area is formed between them. The clamping area is located directly below the plug 8. When the plug 8 is driven downward, both telescopic members can slide against the side of the frustum portion 802 until the two telescopic members are at the top of the step 9 of the cylindrical portion 801. Under the downward elastic action of the elastic member 503, both telescopic members abut against the step 9, thereby locking the position of the plug 8, that is, locking the position of the connecting rod 6. This process can be performed by... Figures 2 to 3 To express.

[0039] It should be noted that the telescopic component can be any component with compression and tension functions in the prior art, such as the spring plunger 7. This article does not limit the type of telescopic component selected, as long as it can achieve the corresponding function.

[0040] exist Figure 3 In the indicated state, to allow the insert block 8 to move upwards to reset, the connection between the cylindrical portion 801 and the connecting rod 6 is set as a rotary connection. Simultaneously, two sets of through slots 10 are provided on the sides of both the cylindrical portion 801 and the frustum portion 802, and these two sets of through slots 10 are arranged opposite to each other. This state allows for... Figure 4 To represent. In Figure 2 During the downward movement of the insert block 8, the plane formed by the two through slots 10 and the plane formed by the two telescopic members are not coplanar. During downward movement, both telescopic members move in contact with the non-through slot portion of the insert block 8 until the positional relationship between the two telescopic members and the insert block 8 is... Figure 3 The state shown. When needed Figure 3 In the indicated state, driving the insert block 8 upward can drive the insert block 8 to rotate until the planes where the two through slots 10 on the insert block 8 are located are coplanar with the planes where the two telescopic members are located. This means that the two telescopic members are inserted into the corresponding through slots 10. At this time, the insert block 8 can move upward under the upward reset action of the elastic member 503, thereby unlocking the insert block 8, which also unlocks the position of the connecting rod 6.

All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
