Description

Technical Field

[0001] This utility model belongs to the technical field of glass manufacturing, specifically relating to a buffer stop structure and a roller conveyor line containing the structure. Background Technology

[0002] In the production of microcrystalline glass, the glass sheets undergo ceramization heat treatment in a roller kiln. This involves heating the glass sheets with a heat source inside the roller kiln, causing them to crystallize and solidify into a dense ceramic structure. To achieve continuous and efficient production, roller kilns are typically used in conjunction with roller conveyor lines. The two ends of the roller conveyor line connect to the kiln inlet and outlet, respectively, with loading and unloading points located near the inlet and outlet. When performing ceramic heat treatment on glass sheets, the glass sheets to be treated are stacked on the support plate of the roller conveyor at the feeding position. The roller conveyor transports the glass sheets to the kiln inlet of the roller kiln through the support plate. The roller kiln drives the support plate at the kiln inlet into the kiln through its own rollers. After treatment, the glass sheets are sent out from the kiln outlet along with the support plate. The roller conveyor transports the support plate at the kiln outlet to the unloading position, where the treated glass sheets are unloaded from the support plate. The roller conveyor then sends the empty support plate back to the feeding position for the next feeding cycle.

[0003] To ensure the cyclical use of the support plates, the roller conveyor line needs to transport the support plates at a speed much faster than that of the roller kiln. Therefore, when the roller conveyor line transports support plates stacked with glass sheets near the kiln inlet, it needs to pause and wait for the previous batch of support plates at the kiln inlet to enter the furnace before resuming operation. To achieve this pause when the support plates approach the kiln inlet, a stop structure needs to be installed on the roller conveyor line near the kiln inlet, such as... Figure 1 As shown, existing blocking structures mostly use a baffle 5 driven by a cylinder 13. When needed, the cylinder drives the baffle to move onto the roller conveyor 15 to block the movement of the bearing plate. However, since the bearing plate on the roller conveyor is moving at a high speed, directly blocking the bearing plate with the baffle can cause the glass sheets stacked on it to slip relative to each other under inertia and impact, resulting in some of them being suspended. The partially suspended glass sheets are prone to deformation and warping during ceramic heat treatment, which will affect the production quality and stability. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a buffer stop structure and a roller conveyor line containing the structure, so as to solve the technical problem that the existing stop structure is prone to causing the glass sheet on the bearing plate to slip, thereby improving the production quality and stability.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A buffer stop structure includes an elastic buffer and a telescopic power source. The elastic buffer includes a housing, one end of a buffer rod is connected inside the housing, and the other end is arranged along the axial direction of the housing and slides out of the housing and is connected to a baffle. Elastic elements are operatively connected to the housing and the buffer rod respectively to absorb the axial impact on the baffle. The telescopic end of the telescopic power source is vertically connected to the housing.

[0007] Furthermore, the telescopic end of the telescopic power source is connected to a mounting base, and the housing is vertically connected to the mounting base. The housing passes through the mounting base and is threadedly connected.

[0008] Furthermore, the mounting base is an L-shaped plate and includes a horizontal plate and a vertical plate connected vertically. The telescopic end of the telescopic power source is vertically connected to the horizontal plate, and the housing vertically penetrates the vertical plate and is threadedly connected.

[0009] Furthermore, the telescopic end of the telescopic power source is vertically connected to a connecting plate, which is parallel to and abuts against the horizontal plate and is connected by multiple vertically arranged bolts.

[0010] Furthermore, the power source for the telescopic movement is a cylinder.

[0011] Furthermore, a cushioning pad is provided on the side of the baffle away from the housing.

[0012] This utility model also includes a roller conveyor line, which includes the buffer stop structure as described above. The buffer stop structure is disposed between two adjacent conveyor rollers and is located below the conveyor rollers. The telescopic power source can drive the elastic buffer to move above the conveyor rollers so as to stop the carrier plate through the baffle.

[0013] Furthermore, in the width direction of the roller conveyor line, the buffer stop structure is located in the middle of the roller conveyor line, and the abutment plate extends to both sides along the width direction of the roller conveyor line.

[0014] Furthermore, the buffer stop structure has multiple components and is distributed at intervals along the width direction of the roller conveyor line.

[0015] Furthermore, a sensor is installed on the transport path of the roller conveyor line. The sensor is used to sense whether a carrier plate passes by at its location. The sensor is electrically connected to the telescopic power source.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The buffer stop structure of this utility model uses an elastic buffer to block the bearing plate through a baffle. The baffle is guided to move by a buffer rod and the impact force is transmitted to the elastic element. The elastic element absorbs the impact force through elastic deformation and slows down the baffle and the blocked bearing plate, thereby preventing the glass sheets stacked on the bearing plate from slipping relative to each other. This can effectively solve the problem that the existing stop structure is prone to causing the glass sheets on the bearing plate to slip, which is conducive to improving production quality and production stability.

[0018] 2. In the buffer stop structure described in this utility model, the telescopic end of the telescopic power source is connected to the shell of the elastic buffer through an L-shaped plate. This not only makes the buffer stop structure more stable and impact-resistant, but also makes it easier to connect and assemble because the shell and the telescopic end of the telescopic power source are connected by vertically connected horizontal and vertical plates respectively. The two connection points are separate and staggered.

[0019] 3. In the buffer stop structure of this utility model, the shell vertically penetrates the vertical plate and is threadedly connected. After the buffer stop structure is installed in place, the position of the elastic buffer can be further adjusted by rotating the shell according to the actual use, which helps to improve the flexibility and practicality of the buffer stop structure.

[0024] The components include: elastic buffer 1, telescopic power source 2, housing 3, buffer rod 4, baffle 5, mounting base 6, L-shaped plate 7, horizontal plate 8, vertical plate 9, nut 10, connecting plate 11, bolt 12, cylinder 13, buffer pad 14, roller conveyor line 15, conveyor roller 16, and bearing plate 17. Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] Example:

[0027] Please see Figure 2 and Figure 3A buffer stop structure includes an elastic buffer 1 and a telescopic power source 2. The elastic buffer 1 includes a cylindrical housing 3. One end of a buffer rod 4 is connected inside the housing 3, and the other end is axially arranged along the housing 3 and slides out of the housing 3, and is vertically connected to a baffle 5. An elastic element (not shown in the figure) is arranged inside the housing 3, and its two ends are respectively connected to the housing 3 and the buffer rod 4 to absorb the axial impact on the baffle 5. The telescopic end of the telescopic power source 2 is vertically connected to the housing 3. In this embodiment, the housing 3 is closed at both ends and has a hole for the buffer rod 4 to extend out at one end. The section of the buffer rod 4 located inside the housing 3 has a radial protrusion. The size of the radial protrusion is larger than the hole to prevent the buffer rod 4 from completely coming out. The elastic element is a helical spring arranged axially along the housing 3. The two ends of the helical spring abut against the radial protrusion and the inner side of the end of the housing 3, respectively.

[0028] In use, the buffer stop structure of this utility model is installed near the kiln inlet, positioned above, below, to the left, or to the right of the roller conveyor line 15. The axial direction of the housing 3 of the elastic buffer 1 is perpendicular to the axial direction of the conveyor roller 16. The baffle 5 is located on the side of the housing 3 away from the kiln inlet. The telescopic power source 2 can move the elastic buffer 1 directly above the roller conveyor line 15, with its height corresponding to the bearing plate 17 on the roller conveyor line 15. When the previous batch of bearing plates 17 at the kiln inlet has not yet entered the roller kiln, and the next batch of bearing plates 17 moves on the roller conveyor line 15 and approaches the kiln inlet, the telescopic end of the telescopic power source 2 is extended, driving the elastic buffer 1 to move above the conveyor roller 16. Subsequently, the bearing plate 17 moves and collides with the baffle 5, causing the baffle 5 to move towards the housing 3. The baffle 5 transmits the impact force through the buffer rod 4. The impact force is delivered to the elastic element, which absorbs the impact force through deformation and gradually slows down the baffle 5 until it stops, thereby stopping the bearing plate 17. When the previous batch of bearing plates 17 at the kiln inlet enters the roller kiln, the telescopic end of the telescopic power source 2 is retracted and drives the elastic buffer 1 to reset, so that the bearing plate 17 is no longer obstructed and is transported to the kiln inlet by the roller conveyor line 15 to achieve continuous production. In the buffer stopping structure described in this utility model, the elastic buffer 1 blocks the bearing plate 17 through the baffle 5, guides the baffle 5 to move through the buffer rod 4 and transmits the impact force to the elastic element. The elastic element absorbs the impact force through elastic deformation and slows down the baffle 5 and the blocked bearing plate 17, thereby preventing the glass sheets stacked on the bearing plate 17 from slipping relative to each other. This can effectively solve the problem that the existing stopping structure is prone to causing the glass sheets on the bearing plate 17 to slip, which is conducive to improving production quality and production stability.

[0029] Please see Figure 2 and Figure 3 The telescopic power source 2 has a mounting base 6 connected to its telescopic end, and the housing 3 is vertically connected to the mounting base 6. The housing 3 passes through the mounting base 6 and is threadedly connected.

[0030] In this way, after the buffer stop structure is installed in place, the position of the elastic buffer 1 can be further adjusted by rotating the housing 3 according to the actual use, so as to adjust the distance between the elastic buffer 1 and the bearing plate 17, which is beneficial to improving the flexibility and practicality of the buffer stop structure.

[0031] Please see Figure 2 and Figure 3 The mounting base 6 is an L-shaped plate 7 and includes a horizontal plate 8 and a vertical plate 9 that are vertically connected. The telescopic end of the telescopic power source 2 is vertically connected to the horizontal plate 8. The housing 3 has external threads and is vertically connected to the vertical plate 9.

[0032] Thus, the mounting base 6 adopts an L-shaped plate 7 with high structural strength, which not only makes the buffer stop structure more stable and impact-resistant, but also connects the housing 3 and the telescopic power source 2 through the vertically connected horizontal plate 8 and vertical plate 9 respectively. The two connection positions are separate and staggered, which also makes it easier to connect and assemble. In this embodiment, a nut 10 is vertically inserted through the vertical plate 9, and the housing 3 passes through the nut 10 and is threaded. The axial dimension of the nut 10 is greater than the thickness of the vertical plate 9, so that the connection between the housing 3 and the mounting base 6 is more stable and reliable without increasing the weight of the mounting base 6.

[0033] Please see Figure 2 and Figure 3 The telescopic power source 2 has a connecting plate 11 vertically connected to its telescopic end. The connecting plate 11 is parallel to and abuts against the horizontal plate 8 and is connected by multiple vertically arranged bolts 12.

[0034] In this way, the telescopic power source 2 is provided with a connecting plate 11 at its telescopic end, which not only increases the contact surface with the horizontal plate 8 and improves the reliability of the connection, but also facilitates the arrangement of bolts 12 for connection. In this embodiment, the telescopic power source 2 is located on the side of the horizontal plate 8 away from the vertical plate 9. The telescopic end of the telescopic power source 2 is welded to the connecting plate 11. There are four bolts 12 distributed in a rectangular shape on the radial outer side of the telescopic end.

[0035] Please see Figure 2 and Figure 3 The telescopic power source 2 is a cylinder 13; the cylinder 13 not only responds quickly and acts reliably, but also has good environmental adaptability and can work stably in the glass production workshop; in implementation, the telescopic power source 2 can also be an electric actuator or a hydraulic cylinder, etc.

[0036] Please see Figure 2 and Figure 3 The side of the baffle 5 away from the housing 3 is covered with a cushioning pad 14; in practice, the cushioning pad 14 can be made of elastic materials such as sponge or rubber.

[0037] In this way, the buffer pad 14 replaces the baffle 5 and directly collides with the bearing plate 17. When the buffer pad 14 is impacted by the bearing plate 17, it undergoes elastic deformation, which not only further improves the buffering effect of the buffer stop structure, but also avoids damage to the bearing plate 17 due to impact, thus improving the practicality of the buffer stop structure.

[0038] Please see Figure 3 and Figure 4 This embodiment also includes a roller conveyor line 15 using the buffer stop structure. The buffer stop structure is located between two adjacent conveyor rollers 16 near the kiln inlet on the roller conveyor line 15. The buffer stop structure is located below the conveyor rollers 16. The telescopic power source 2 can drive the elastic buffer 1 to move above the conveyor rollers 16 so as to stop the bearing plate 17 by the baffle 5.

[0039] In practice, the buffer stop structure can also be set above, to the left or to the right of the roller conveyor 15, or below the conveyor roller 16 of the roller conveyor 15. This not only makes reasonable use of the space below the roller conveyor 15 and avoids interference with other production equipment, but also, compared to setting the buffer stop structure above, to the left or to the right of the roller conveyor 15, setting it below the conveyor roller 16 of the roller conveyor 15 results in a lower installation position for the telescopic power source 2, which helps to reduce the volume and material consumption of the support and fixing structure required for the telescopic power source 2.

[0040] Please see Figure 3 and Figure 4 In the width direction of the roller conveyor 15, the buffer stop structure is located in the middle of the roller conveyor 15, and the abutment plate extends to both sides along the width direction of the roller conveyor 15.

[0041] In this way, the contact plate extends along the width of the roller conveyor line 15, increasing the contact area with the bearing plate 17. This arrangement is suitable for production situations where the bearing plate 17 and the glass sheet on it are small and the impact force from the impact is weak.

[0042] In one embodiment, the buffer stop structure is multiple and spaced apart along the width direction of the roller conveyor line 15.

[0043] In this way, multiple buffer stops are distributed at intervals along the width of the roller conveyor 15, which not only increases the contact area with the bearing plate 17, but also increases the buffering capacity of the roller conveyor 15 to stop the bearing plate 17. This arrangement is suitable for production situations where the bearing plate 17 and the glass sheet on it are large and the impact force from the impact is strong.

[0044] In one embodiment, on the transport path of the roller conveyor 15, a sensor (not shown in the figure) is provided on the side of the buffer stop structure away from the kiln inlet. The sensor is used to sense whether the bearing plate 17 has passed by the location. The sensor is electrically connected to the telescopic power source 2.

[0045] In this way, when the support plate 17 moves close to the kiln inlet on the roller conveyor line 15 and triggers the sensor, the sensor sends a control signal to control the telescopic power source 2 to move, causing the telescopic end of the telescopic power source 2 to extend and drive the elastic buffer 1 to move into place, thereby stopping the support plate 17. The automatic control of the telescopic power source 2 by the sensor to achieve the stopping function not only reduces the possibility of misoperation compared to manual control, but also helps to improve the automation level of production. In practice, the telescopic power source 2 can be manually judged and controlled to release the stopping function, or another sensor can be set at the kiln inlet and electrically connected to the telescopic power source 2. When there is no support plate 17 at the kiln inlet, the sensor at the kiln inlet is triggered and controls the telescopic power source 2 to retract the telescopic end. The control priority of the sensor at the kiln inlet is higher than that of the other sensor, thereby realizing the fully automatic control of the stopping function.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
