Description

Technical Field

[0001] This utility model mainly relates to the field of heat treatment furnace technology, specifically to an anti-collision guiding conveyor device for heat treatment furnaces. Background Technology

[0002] In the heat treatment process, workpieces are often transported into the heat treatment furnace via a conveying device. However, existing conveying devices lack effective guiding and anti-collision structures, causing workpieces to easily deviate, shake, or even collide with the furnace wall or other components during transport. This not only damages the workpieces and affects the heat treatment effect but may also damage the equipment, posing significant safety hazards.

[0003] Existing conveying devices only use simple conveyor belts for transport. During operation, the conveyor belts are prone to deviation, causing the workpiece position to shift. In addition, the guide structure is mostly designed with rigid connections, which cannot flexibly adjust the guide range according to actual needs. As a result, a single conveying device can often only be adapted to a single type of furnace or product, resulting in low equipment versatility and increased equipment investment costs for enterprises.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0029] See attached document Figures 1-4A collision-proof guiding conveyor for a heat treatment furnace includes a roller conveyor line 1. Side frames 3 are provided on both sides of the roller conveyor line 1. Guide wheel sets 4 and buffer guide plates 5 are sequentially provided on the upper end of the side frames 3. Multiple sets of adjustment modules 6 are provided on the outer side of the guide wheel sets 4 and buffer guide plates 5, and are all located near one end of the heat treatment furnace. Sensing modules 2 are provided at both ends of the adjustment modules 6. The sensing modules 2 are located at the rear end of the buffer guide plates 5. The adjustment module 6 includes an angle bracket 301 fixedly connected to the outer side of the side frame 3. An adjustment rod 302 is fixedly connected to the upper end of the angle bracket 301. A spring column 303 and a spring column 304 perpendicular to the adjustment rod 302 are provided on the adjustment rod 302.

[0030] The side frame 3 is made of steel plate bending and is fixed to the frame on both sides of the roller conveyor line 1 by bottom flange plate bolts to ensure a stable connection. The upper surface of the side frame 3 has multiple parallel sliding grooves along the conveying direction, and wear-resistant copper sleeves are embedded in the grooves to reduce friction loss when the subsequent guide wheel group slides.

[0031] The guide wheel assembly 4 has a boss welded to its lower end to match the sliding groove of the side frame 3. The boss has a T-shaped cross-section and is embedded in the sliding groove to form a sliding connection. The guide wheel assembly 4 consists of a sliding seat 401 and multiple guide wheels 402 arranged in parallel. The guide wheels 402 are rotatably connected to the sliding seat 401 through pins. The wheel body is made of polyurethane material, which has a certain elasticity to buffer collisions and avoid scratching the product surface. The guide wheels 402 protrude from the inner side wall of the side frame 3 and can directly contact the side of the conveyed product to achieve real-time guidance.

[0032] The buffer guide plate 5, as a secondary buffer guide component for product conveying, is made of stainless steel plate and is shaped like a "trumpet mouth". The middle section is a straight structure, and the two ends are outwardly curved sections. The edges of the curved sections are polished to avoid scratching the product. The buffer guide plate 5 is installed on the upper end of the side frame 3 through spring column 303. The installation position is slightly off the outside of the guide wheel group 4 and maintains a certain vertical distance from the guide wheel group 4. It can be adapted according to the product height and is suitable for products that are narrow at the bottom and wide at the top. This installation method does not affect the primary guidance of the guide wheel group and can correct large deviations of the product in advance through the curved sections.

[0033] The adjustment module 6 serves as the core for adjusting the position of the guide wheel assembly 4 and the buffer guide plate 5. Each side frame 3 corresponds to multiple adjustment modules, including a corner bracket 301, an adjustment rod 302, a first spring post 303, a second spring post 304, and a nut 305. The corner bracket 301 is an L-shaped stainless steel part, which is fixed to the outer wall of the side frame 3 by bolts. The adjustment rod 302 is a chrome-plated round rod, with one end welded to the corner bracket 301 and the other end extending to the outside of the guide wheel assembly 4. The first spring post 303 corresponding to the buffer guide plate 5 and the second spring post 304 corresponding to the guide wheel assembly 4 are both "sleeve + spring" structures, which are directly connected to the adjustment rod 302. The adjustment rod 302 has a radial through hole. The screw at one end of the spring post passes through the through hole and is locked by double nuts 305 to achieve a detachable connection. Loosening the nuts can adjust the extension length of the spring post. Among them, the length of spring column 1 303 is greater than the length of spring column 2 304, which is adapted to the outer installation position of the buffer guide plate 5, ensuring that both can achieve buffering and position adjustment through the extension and retraction of the spring column.

[0034] Sensing Module 2: As a collision avoidance detection unit, each side frame 3 has one set at each end, including an L-shaped mounting plate 201 and a pressure sensor 202. The L-shaped mounting plate 201 is made of carbon steel and is fixed to the outside of the side frame 3 by bolts. The waist-shaped groove 203 on the upper end can be used to fine adjust the installation position of the pressure sensor 202. The pressure sensor 202 is an explosion-proof digital display pressure sensor and is fixed in the waist-shaped groove 203 by bolts. Its detection end contacts the back of the buffer guide plate 5 and can be connected by an elastic gasket to avoid hard contact damage to the sensor. It detects the pressure value of the buffer guide plate 5 in real time.

[0035] The core function of this device is to precisely guide the product before it enters the heat treatment furnace, preventing collisions caused by product conveying deviations. It is equipped with a PLC automatic control system and alarm function. Connected to the pressure sensor 202 of sensing module 2 via a shielded signal cable, it can collect pressure data in real time. Simultaneously, the PLC system connects to the drive mechanism and audible / visual alarm of roller conveyor line 1 to achieve automated control. The specific functions and operating logic are as follows:

[0036] Guiding function: When the product is placed on the roller conveyor line 1, it is conveyed towards the heat treatment furnace as the rollers rotate; the product first enters the bending section of the buffer guide plate 5, and the "trumpet mouth" structure of the bending section can guide the product with slight deviation to gradually correct itself; if the product deviation is small, after being guided by the buffer guide plate 5, the side contacts the guide wheel 402 of the guide wheel group 4, the guide wheel rotates to reduce friction, further correct the position, and ensure that the product is conveyed to the furnace mouth along the correct path.

[0037] Anti-collision and automatic control functions: When the product deviation is large, the bending section of the buffer guide plate 5 will be continuously squeezed during the conveying process. After being subjected to force, the buffer guide plate 5 moves outward and compresses the first spring column 303. At the same time, the side of the product may simultaneously squeeze the guide wheel group 4, causing it to slide outward along the sliding groove and compress the second spring column 304. When the pressure on the buffer guide plate 5 reaches the set threshold (which can be preset by the PLC system), the pressure sensor 202 transmits the detection signal to the PLC. The PLC system immediately triggers a dual response, and the conveyor line automatically stops to prevent the product from continuing to be conveyed and causing a collision. After the staff investigates the cause of the product deviation and makes adjustments, the conveyor line is restarted. At this time, the first spring column 303 and the second spring column 304 are reset under the action of spring force, driving the buffer guide plate 5 and the guide wheel group 4 back to the initial position.

[0038] Adaptive adjustment function: The installation positions of the guide wheel assembly 4 and the buffer guide plate 5 can be flexibly adjusted according to the width of the furnace inlet channel of the heat treatment furnace. Loosen the nuts 305 of the spring column 1 303 and the spring column 2 304 in the adjustment module 6, and manually adjust the extension length of the spring column according to the width of the furnace inlet channel. After the adjustment is completed, tighten the double nuts 305 to ensure that the position of the spring column is fixed. At this time, the guiding range of the guide wheel assembly 4 and the buffer guide plate 5 matches the furnace inlet channel to meet the usage requirements of furnaces of different specifications.

[0039] In summary, this device features dual guiding and buffering, balancing large deviation correction and low-friction guidance, adapting to product conveying with different precision requirements. It also has intelligent anti-collision and alarm response, reducing manual monitoring costs. The adjustment module can be adapted to heat treatment furnace inlet channels of different widths, making the equipment highly versatile.

[0040] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
