Description

Technical Field

[0001] The utility model belongs to the technical field of rock wool strip conveying equipment, in particular to a rock wool strip conveying anti-falling mechanism. Background Art

[0002] In the production of rock wool composite panels, the filling of rock wool strips is a critical step. While the conveying of rock wool strips of varying thicknesses on the production line should be smooth and orderly, the reality presents numerous challenges. Traditional rock wool production lines are prone to tipping over during conveyance due to the strips' inherent physical properties, such as softness, a certain degree of elasticity, and irregular shape. This is particularly true with thinner strips.

[0003] If a rock wool strip topples during transport, it triggers a chain reaction. From a production process perspective, this directly disrupts the normal transport path of subsequent rock wool strips, disrupting the production rhythm of all subsequent strips. Once the production rhythm is disrupted, the efficiency of the entire production line will be severely affected, not only increasing production costs (such as energy waste and increased equipment idle time), but also potentially affecting product quality. For example, a disrupted production rhythm can lead to uneven filling of rock wool strips in a composite panel, affecting key indicators such as the thermal insulation performance of the rock wool composite panel.

[0004] To overcome this serious production bottleneck, traditional production lines employ a relatively primitive solution: adding a monitoring operator to the sliver conveyor station. This operator's primary responsibility is to promptly detect and recover fallen slivers. However, this solution has numerous drawbacks. First, it increases labor costs, a significant expense for businesses, especially in today's rapidly rising labor costs. Second, manual operation is subject to uncertainty and delays. Operators may fail to detect fallen slivers due to fatigue or negligence, effectively preventing disruptions to production rhythm. Furthermore, manual operation is relatively inefficient, making it difficult to meet the demands of ever-increasing production speeds and scale. Utility Model Content

[0005] In view of this, the utility model aims to propose a rock wool strip conveying anti-falling mechanism. This anti-falling mechanism overcomes the above shortcomings. On the basis of traditional production line equipment, an upper roller is added, which moves simultaneously with the rear roller to protect the rock wool strips from top to bottom and transport them forward, greatly avoiding the possibility of the cotton strips falling. It has a simple and compact structure and good reliability.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0007] A rock wool strip conveying and anti-falling mechanism includes a reduction motor, a drive motor, a front roller, an upper roller, a rear roller, a gear, a lifting platform, and a machine. The front roller is arranged on the machine, the reduction motor is connected to the front roller by transmission, the rear roller is arranged on the machine, the rear roller is arranged behind the front roller and connected to the front roller, the drive motor is connected to the rear roller by transmission, the lifting platform is fixed on the machine and arranged above the rear roller, the upper roller is hoisted on the lifting platform, and gears are respectively arranged on the same side of the upper roller and the rear roller, and are connected through gear transmission. Preferably, the front roller drive shaft is connected to the driving end of the reduction motor by a belt, the reduction motor drives the front roller to move, the rear roller drive shaft is connected to the driving end of the drive motor by a belt, the drive motor drives the rear roller to move, gears are arranged on the same side of the drive shafts of the upper roller and the rear roller, and the gears are engaged with each other so that the upper roller and the rear roller move synchronously.

[0008] One structure that optimizes the aforementioned solution also includes a platform fixed to the machine table and positioned behind the rear roller conveyor. This platform allows the rock wool strips to fall onto the platform after falling from the rear roller conveyor. A propulsion mechanism is incorporated into the platform to push and align the rock wool strips in an orderly manner, preparing them for subsequent processing steps. This serves as a transition and organization mechanism between the delivery of the rock wool strips and subsequent processing steps.

[0009] In a structure that optimizes the aforementioned solution, a protective plate is further included, disposed outside the gear. The protective plate effectively shields the meshing structure of the gears, preventing operators from accidentally touching the gears and causing operational hazards during equipment operation, thereby improving equipment safety and protecting the operator's personal safety.

[0010] Furthermore, the platform is arranged below the horizontal plane of the rear roller, and a height difference is formed between the rear rollers, so that the rock wool strips fall onto the platform after falling from the rear rollers, which is convenient for subsequent process operations.

[0011] Furthermore, the driving motor is a servo motor, which can more accurately control the movement of the rear roller, which helps to accurately adjust the spacing of the rock wool strips when working in conjunction with the front roller.

[0012] In a structure that can optimize the above solution, five front roller track timing belts are arranged in parallel on the front roller track. The front roller track timing belts are evenly distributed on the front roller track and connected by the front roller track drive shaft to achieve synchronous operation.

[0013] In a structure that can optimize the above solution, five rear roller synchronous belts are arranged in parallel on the rear roller. The rear roller synchronous belts are evenly distributed on the rear roller and connected by the rear roller drive shaft to achieve synchronous operation.

[0014] In a structure that optimizes the aforementioned solution, the front and rear rollers are located in the same horizontal plane and partially overlap, and the front and rear roller synchronous belts are arranged alternately. The front and rear rollers are located in the same plane and partially overlap, which allows the rock wool strips to be transported smoothly from the front roller to the rear roller. Due to the different speeds of the front and rear rollers, the rock wool strips that were tightly packed on the front roller are automatically separated into equal distances on the rear roller. The presence of the upper roller prevents the rock wool strips from tipping over on the rear roller.

[0015] In a structure that optimizes the above solution, two upper roller conveyor timing belts are installed in parallel on the upper roller conveyor. The upper roller conveyor timing belts are evenly distributed on the upper roller conveyor and connected by the upper roller conveyor drive shaft to achieve synchronous operation. At the same time, the gear on one side of the upper roller conveyor drive shaft meshes with the gear on the rear roller conveyor drive shaft, thereby providing synchronous power drive for the upper roller conveyor.

[0016] In a structure that can optimize the aforementioned solution, the lifting platform includes a gantry, a vertical connecting block, a bearing seat, and an adjusting bolt. The gantry is fixed to the machine platform, and a number of vertical connecting blocks are hoisted on the gantry. The bearing seat is connected to the vertical connecting block via an adjusting bolt, and the upper roller is set on the lifting platform via the bearing seat. The upper roller drive shaft passes through the bearing seat, and the lifting platform is adjusted up and down by adjusting the bolts, so that the two upper roller synchronous belts maintain a 2-5mm gap with the upper surface of the rock wool strip, which can effectively prevent the rock wool strip from tipping over without causing excessive resistance to the transportation of the rock wool strip. There are at least two groups of gantries, at least one group of gantries is connected to the upper roller via the bearing seat, and the other group of gantries can be connected to the upper roller via the bearing seat, or can be directly connected to the upper roller body via a connector.

[0017] Compared with the prior art, the rock wool strip conveying and anti-falling mechanism described in the present invention has the following advantages:

[0018] This solution addresses the existing problem of rock wool strips being prone to tipping over during transport, particularly thin strips, which can disrupt production rhythm. In this solution, the front and rear rollers partially overlap, with alternating timing belts. The different speeds of the front and rear rollers automatically adjust the spacing between the rock wool strips. This, combined with the synergistic effect of the upper roller, effectively prevents rock wool strips from tipping over on the rear roller. Furthermore, a lifting platform precisely adjusts the gap between the upper roller and the rock wool strips, ensuring stable transport and minimizing production rhythm disruptions.

[0019] This solution incorporates numerous design features to enhance production efficiency. Firstly, the front and rear rollers automatically adjust the spacing between the rock wool strips, eliminating the need for manual intervention and reducing production downtime. Secondly, the servo motors used in the rear rollers precisely control the movement of the rear rollers, facilitating accurate adjustment of the spacing between the rock wool strips when working in conjunction with the front rollers. This automates the production process, improving both production efficiency and product quality.

[0020] Traditional production lines may have safety issues. This solution addresses this by installing a protective plate. Located on the outside of the gears, the plate effectively shields the gear meshing structure, preventing operators from accidentally touching the gears and potentially causing danger. This significantly improves equipment safety and protects operators.

[0021] In this solution, the platform is positioned behind and below the rear roller conveyor. As the rock wool strips fall from the rear roller conveyor onto the platform, they fall flat on their backs. A push mechanism on the platform arranges the strips in an orderly fashion, ready for subsequent processing. This design provides a smooth transition and organization between strip delivery and subsequent processing, improving production continuity and efficiency.

[0022] In this solution, the five synchronous belts of the front roller, the five synchronous belts of the rear roller, and the two synchronous belts of the top roller are connected by their own drive shafts to achieve synchronous operation. This synchronous belt configuration ensures smooth and orderly conveying of the rock wool strips on each roller, preventing problems such as rock wool strip shaking, tipping, or poor conveying caused by asynchronous synchronous belts, thereby improving the reliability and stability of the entire conveying and anti-tip mechanism.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0036] A rock wool strip conveying anti-fall mechanism includes a reduction motor 1, a drive motor 2, a front roller 3, an upper roller 5, a rear roller 7, a gear 9, a lifting platform 10, a machine platform 11, a platform 8 and a protective plate 12 and other components.

[0037] The front roller 3 is mounted on the machine platform 11 and is connected to the reduction motor 1 via a belt. The front roller 3 is driven by a belt connecting the front roller's drive shaft to the reduction motor's drive end. Five parallel front roller timing belts 3.1 are evenly distributed across the front roller and connected by the front roller's drive shaft for synchronized operation.

[0038] The rear roller conveyor 7 is also mounted on the machine platform 11, located behind and connected to the front roller conveyor 3. The drive motor 2 is a servo motor connected to the rear roller conveyor 7. Specifically, the rear roller conveyor's drive shaft is connected to the drive end of the drive motor via a belt. Five rear roller conveyor timing belts 7.1 are arranged parallel to the rear roller conveyor 7, connected by the rear roller conveyor's drive shaft for synchronized operation. The front roller conveyor 3 and the rear roller conveyor 7 are located in the same horizontal plane and partially overlap, with the front roller conveyor timing belts 3.1 and the rear roller conveyor timing belts 7.1 alternating.

[0039] The lifting platform 10 is fixed to the machine platform 11 and is located above the rear roller 7. It consists of a gantry 10.1, a vertical connecting block 10.2, a bearing seat 10.3, and an adjusting bolt 10.4. The gantry 10.1 is fixed to the machine platform 11, and several vertical connecting blocks 10.2 are hoisted on the gantry 10.1. The bearing seat 10.3 is connected to the vertical connecting block 10.2 via the adjusting bolt 10.4. The upper roller 5 is set on the lifting platform 10 via the bearing seat 10.3. The upper roller drive shaft passes through the bearing seat, and the lifting platform can be adjusted up and down by the adjusting bolt. Two upper roller synchronous belts 5.1 are set in parallel on the upper roller 5. The upper roller synchronous belts are evenly distributed on the upper roller and are connected by the upper roller drive shaft to achieve synchronous operation. Gears 9 are set on the same side of the drive shaft of the upper roller and the rear roller. The gears engage with each other, so that the upper roller and the rear roller move synchronously.

[0040] The platform 8 is fixed on the machine table 11 and is located behind the rear roller 7. The platform 8 is arranged below the horizontal plane where the rear roller 7 is located. The platform is provided with a pushing mechanism. A protective plate 12 is arranged on the outside of the gear 9.

[0041] Working principle:

[0042] First, the reduction motor 1 is started, and the power is transmitted to the drive shaft of the front roller 3 via a belt. The five front roller timing belts 3.1 operate synchronously, placing the rock wool strips on the front roller 3, which are driven by the timing belts to transport them forward smoothly. When the rock wool strips are transported to the overlapping part of the front roller 3 and the rear roller 7, due to the different speeds of the two and the alternating arrangement of the timing belts, the closely arranged rock wool strips are automatically arranged at equal distances on the rear roller. At the same time, the servo motor, i.e., the drive motor 2, is started to precisely control the movement of the rear roller 7 to ensure a smooth transition and accurate spacing adjustment. Next, the upper roller 5 is positioned above the rock wool strips, supported by the lifting platform 10, and moves synchronously with the rear roller 7 via the gear 9 transmission. The adjusting bolts 10.4 of the lifting platform 10 are adjusted to maintain a gap of 2-5 mm between the two upper roller timing belts 5.1 and the upper surface of the rock wool strips. The two work together to prevent the rock wool strips from tipping over on the rear roller 7. After the rock wool strips fall from the rear roller 7, they fall onto the platform 8 behind it and below the horizontal plane of the rear roller. The pushing mechanism on the platform 8 works to arrange the rock wool strips in an orderly manner in preparation for the subsequent process. During operation, the protective plate 12 always effectively blocks the meshing structure of the gear 9, preventing operators from accidentally touching the gear 9 and ensuring safe operation of the equipment.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
