Description

Technical Field

[0001] This utility model relates to the technical field of vacuum glass production and processing equipment, specifically to a movable material rack for vacuum glass production. Background Technology

[0002] Currently, the production of vacuum glass mainly uses individual furnaces to perform operations such as edge sealing, vacuuming, and sealing on the vacuum glass to be processed.

[0003] Combination Figure 1 As shown, each individual furnace contains multiple rack assemblies, each with multiple layers. These rack assemblies can be assembled and transported as a whole. Each rack layer holds a maximum of four paired pieces of vacuum-tempered glass awaiting processing. During production, a corresponding number of vacuum sealing devices, positioned at specific locations on the furnace sidewalls and extending to each rack layer, are installed onto the lower sheet of glass to be processed. These devices are coaxially aligned with the evacuation holes of the lower sheet. After installation, the furnace door is closed, and the individual furnace begins processing according to a pre-set program. Each vacuum sealing device within the furnace corresponds to one piece of vacuum-tempered glass to be processed, arranged sequentially at the four corners of the individual furnace.

[0004] Combination Figure 2 As shown, each shelf 2 in each shelf group has a hollow cylindrical column 4 at its lower corner to support each shelf 2 and maintain a fixed spacing. Furthermore, a tapered positioning pin 3 is provided at the end of the uppermost shelf in each shelf group, opposite the column 4. When multiple shelf groups are stacked to form a whole, the positioning pin 3 on the lower shelf 2 embeds into the column 4 on the upper shelf, serving as a positioning connection and preventing misalignment during transport after assembly. When placing glass, it is inserted into the shelf between two adjacent columns.

[0005] In the existing technology, both the column 5 and the positioning pin 3 are welded and fixed to the material rack. Since the positioning pin and the column are fixed, the placement of the glass is restricted, making it impossible to place some glass that exceeds the span between adjacent columns, resulting in a reduction in the furnace loading rate. Utility Model Content

[0006] This utility model provides a movable material rack for vacuum glass production, which aims to make full use of the rack's space, adapt the position of the support pins to the size of the glass to be loaded, avoid obstructing or interfering with the glass placement, and improve the furnace loading rate.

[0007] This utility model is achieved through the following technical solution: a movable material rack for vacuum glass production, including a material rack assembly, the material rack assembly including multiple layers of material racks, a support pin connecting two adjacent layers of material racks, and multiple insertion holes are provided around the material rack along its length, the insertion holes penetrating the top and bottom of the material rack.

[0008] The support pin includes a column, and the top and bottom ends of the column are connected to positioning pins; the positioning pins at the top and bottom ends of the column can be inserted into the insertion holes on two adjacent material racks to connect the two material racks.

[0009] Compared with existing technologies, this solution has the following advantages and beneficial effects:

[0010] In this solution, the upper and lower shelves are connected by a freely detachable support pin, replacing the existing method of fixing the upper and lower shelves by columns. The support pin in this solution includes a column and positioning pins connected to the top and bottom of the column. The positioning pins at the top and bottom of the column are inserted into the insertion holes of the upper and lower shelves, respectively, thereby realizing the positioning connection between the upper and lower adjacent shelves. Each side of the shelf has multiple insertion holes, so the position of the support pin can be adjusted according to the size of the glass to be loaded, so that the positioning pin in the support pin is inserted into the corresponding insertion hole, allowing the glass to be placed smoothly on the shelf.

[0011] In this solution, the multi-layer shelf is connected by support pins, allowing for flexible connections between the shelves. This enables the support pins to be adjusted according to the glass size, effectively preventing restrictions on glass placement and maximizing the use of shelf space. The support pin positions can be adjusted as needed.

[0012] When the size of the glass to be loaded exceeds the original span between the columns, the position of the support pins can be adjusted to avoid placing the glass, thus avoiding obstruction or interference during the glass placement process. This allows for full utilization of the rack space, maximizing the amount of glass to be processed and effectively improving the furnace loading rate.

[0013] Furthermore, the material rack includes horizontal beams and vertical beams that are perpendicularly connected to each other, and multiple insertion holes are provided on both the horizontal beams and vertical beams of the material rack.

[0014] Beneficial effects: The material rack in this solution, including the crossbeams and longitudinal beams, can improve the stability and robustness of the entire material rack. In addition, multiple insertion holes are opened on both the crossbeams and longitudinal beams, which not only increases the installation positions of the support pins, but also reduces the weight of the material rack.

[0015] Furthermore, both the crossbeam and the longitudinal beam have multiple spaced weight-reducing holes sequentially opened on their sides along their length.

[0016] Beneficial effects: The weight-reducing holes opened on the crossbeams and longitudinal beams in this design can reduce the weight of the material rack, making it easier to transport. At the same time, it can also reduce the heat storage of the material rack and accelerate the heating and cooling speed.

[0017] Furthermore, both the crossbeam and the longitudinal beam are hollow square tubes.

[0018] Beneficial effects: The crossbeams and longitudinal beams in this design are all hollow square tubes, which can further reduce the weight of the entire material rack.

[0019] Furthermore, the top and bottom ends of the support pin column are respectively connected to an upper pad and a lower pad, and the positioning pins on the top and bottom ends of the column are respectively connected to the upper pad and the lower pad, and the area of ​​the upper pad and the lower pad is larger than the bottom area of ​​the column.

[0020] Beneficial effects: The upper and lower pads in this design increase the contact area and reduce the pressure on the contact surface, thus dispersing the pressure and preventing deformation of the support points.

[0021] Furthermore, the column, the upper pad, the lower pad, and the positioning pin are integrally formed.

[0022] Beneficial effects: With this design, all components are integrally molded to form a support pin, which can be used directly without assembly, making it convenient to operate.

[0023] Furthermore, the column, the upper pad, the lower pad, and the positioning pin are detachably connected.

[0024] Beneficial effects: This solution provides an alternative connection method for the various components of the support pin. The components are detachable and require assembly during use, which makes production and processing easier and reduces production costs.

[0025] Furthermore, the end of the positioning pin furthest from the column is tapered.

[0026] Beneficial effect: The conical shape at the end of the positioning pin in this solution can guide the positioning pin into the socket, making it easier and faster to insert the positioning pin into the socket.

[0027] Furthermore, the number of positioning pins at the top of the column and at the bottom of the column is one or more.

[0028] Beneficial effects: When there is more than one locating pin at both ends of the column in this solution, the number of anchoring points can be increased, which helps to improve the support stability of the material rack.

[0029] Furthermore, at least two positioning pins are provided at the top of the column, and one positioning pin is provided at the bottom of the column.

[0030] Beneficial effects: This design incorporates at least two locating pins at the top of the columns, enhancing the stability of the support frame. However, when placing the glass, it is positioned within the space formed by the upper and lower shelves, with the upper surface of the lower shelf providing support.

[0031] In this solution, only one positioning pin is set at the bottom of the column. This avoids occupying too much space on the lower shelf where glass is placed, and also avoids the problem of too many positioning pins at the bottom of the column reducing the range of adjustment of the support pin on the shelf. Since there is only one positioning pin at the bottom of the column, the position of the support pin can be adjusted at will, which greatly reduces the impact of the positioning pin at the bottom of the column on the glass placement position and effectively utilizes the shelf space to accommodate more sizes and specifications of glass.

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0044] Example 1

[0045] like Figure 3 , Figure 4 and Figure 5 As shown, this embodiment 1 provides a movable material rack for vacuum glass production, including a material rack assembly. In practical applications, multiple material rack assemblies in this embodiment can be stacked to form a whole and placed in a single furnace according to actual needs.

[0046] The rack assembly in this embodiment includes multiple racks 2, with support pins connecting adjacent racks 2. Thus, adjacent racks 2 are supported and connected by support pins to form a space for placing glass 1.

[0047] Multiple insertion holes 7 are provided around the material rack 2 along its length. The insertion holes 7 pass through the top and bottom of the material rack 2, thus making the insertion holes 7 a through hole structure. The shape of the insertion holes 7 is not specifically limited. The insertion holes 7 can be circular holes, square holes or polygonal holes. In this embodiment, the insertion holes 7 are described using circular holes as an example.

[0048] In this embodiment, the material rack 2 includes horizontal beams and vertical beams connected perpendicularly to each other. Multiple insertion holes 7 are provided on both the horizontal beams and vertical beams of the material rack 2. The insertion holes 7 are evenly distributed on the horizontal beams and vertical beams. Multiple weight-reducing holes 8 are sequentially provided along the length of both the horizontal beams and the vertical beams. The weight-reducing holes 8 on the horizontal beams and vertical beams pass through both sides of the horizontal beams and vertical beams, and in this embodiment, the weight-reducing holes 8 are elongated holes.

[0049] In this embodiment, both the crossbeams and longitudinal beams are hollow square tubes. The hollow crossbeams and longitudinal beams, as well as the weight-reducing holes 8 and insertion holes 7, greatly reduce the weight of the entire material rack 2, which is beneficial for transportation. At the same time, it also effectively reduces the heat storage of the material rack 2 and accelerates the heating and cooling speed.

[0050] In this embodiment, at least four support pins are provided. These four support pins can respectively support the four corners of the material rack 2, thereby improving the stability of the material rack 2. Combined with... Figure 4 and Figure 5As shown, the support pin includes a column 4, and a positioning pin 3 is connected to both the top and bottom of the column 4. In this embodiment, the positioning pins 3 at the top and bottom of the column 4 are threaded, welded, or integrally formed with the column 4.

[0051] The column 4 is hollow inside. In this embodiment, the shape of the column 4 is not limited to a cylinder, but can be other shapes, which are not specifically limited here. The positioning pins 3 at the top and bottom of the column 4 can be inserted into the insertion holes 7 on the two adjacent material racks 2 to connect the two material racks 2. In this embodiment, the positioning pins 3 are matched with the size of the insertion holes 7 on the material racks 2 and can be inserted into the insertion holes 7. In this embodiment, the end of the positioning pin 3 away from the column 4 is tapered, which makes it easier and faster to insert into the insertion holes 7.

[0052] The number of positioning pins 3 at the top and bottom of the column 4 is one or more. In this embodiment, the number of positioning pins 3 at the top and bottom of the column 4 is one.

[0053] The specific implementation process is as follows:

[0054] In use, the multi-layer material rack 2 is connected sequentially from bottom to top by support pins. The two adjacent material racks 2 are connected by four support pins. The two positioning pins 3 in the support pins are inserted into the insertion holes 7 of the upper and lower material racks 2 respectively. When placing the glass 1, the glass 1 is placed into the space formed by the upper and lower material racks 2 between the two adjacent support pins.

[0055] When the size of the glass 1 to be loaded exceeds the span between the two support pins, the position of the support pins can be adjusted according to the size of the glass 1 when installing the material rack 2 to avoid interference with the placement of the glass 1. This allows for full utilization of the space in the material rack 2, maximizing the placement of as many glass 1 to be processed as possible, thereby improving the furnace loading rate.

[0056] Example 2

[0057] like Figure 4 As shown, the difference between this embodiment and embodiment 1 is that: in this embodiment, the top and bottom ends of the support pin column 4 are respectively connected to the upper pad 5 and the lower pad 6, and the positioning pins 3 on the top and bottom ends of the column 4 are respectively connected to the upper pad 5 and the lower pad 6. The area of ​​the upper pad 5 and the lower pad 6 is larger than the bottom area of ​​the column 4, that is, the width of the upper pad 5 and the lower pad 6 is larger than the diameter of the column 4.

[0058] The column 4, upper pad 5, lower pad 6 and positioning pin 3 are integrally formed. The column 4, upper pad 5, lower pad 6 and positioning pin 3 can also be connected by a detachable connection method (such as threaded connection, screw connection, etc.).

[0059] In this embodiment, the upper pad 5 and the lower pad 6 can increase the contact area, reduce the pressure on the contact surface, and play a role in dispersing the pressure, thereby avoiding deformation of the support point.

[0060] Example 3

[0061] like Figure 6 As shown, the difference between this embodiment and embodiment 2 is that: in this embodiment, there are at least two positioning pins 3 at the top of the column 4 and one positioning pin 3 at the bottom of the column 4. In this embodiment, two positioning pins 3 at the top of the column 4 are set as an example. The two positioning pins 3 at the top of the column 4 are arranged parallel to each other and installed at intervals on the upper surface of the upper pad 5, while the positioning pin 3 at the bottom of the column 4 is installed on the lower pad 6.

[0062] The distance between the two positioning pins 3 at the top of the column 4 is the same as the distance between the two adjacent insertion holes 7 on the material rack 2, so that the two positioning pins 3 on the column 4 can be smoothly inserted into the two adjacent insertion holes 7. The two positioning pins 3 at the top of the column 4 can enhance the support stability of the material rack 2, while only one positioning pin 3 is set at the bottom of the column 4, which is even more effective. Under the effect of enhancing the support stability of the material rack 2, the space of the material rack 2 can be utilized as much as possible, and interference with the placement of the glass 1 can be reduced.

[0063] Example 4

[0064] like Figure 7 As shown, the difference between this embodiment and Embodiment 2 is that in this embodiment, there is one positioning pin 3 at the top of the column 4, and two positioning pins 3 at the bottom of the column 4. This embodiment provides another structure for the support pins, which can also improve the support stability of the material rack 2.

[0065] Example 5

[0066] like Figure 8 As shown, the difference between this embodiment and embodiment 3 is that in this embodiment, two positioning pins 3 are provided at both the top and bottom of the column 4. This embodiment provides another structure for the support pins, which can further improve the support stability of the material rack 2.
