Description

Technical Field

[0001] This utility model belongs to the field of ovens, and in particular to an oven roller mechanism. Background Technology

[0002] The existing bread oven includes an oven body 1, inside which are installed multiple parallel rollers 2. The rollers 2 are horizontally positioned, and their two ends are rotatably mounted to the side walls of the oven body 1. One side wall of the oven body 1 has an openable and closable oven door 3. When baking bread, the bread dough is evenly placed on a tray 4, then the tray 4 is moved into the oven door 3, and one end of the tray 4 is placed on the rollers 2. Figure 3 As shown. Then push tray 4, pushing it completely into furnace body 1, and then close furnace door 1, as shown. Figure 4 As shown. After the bread is baked, open oven door 3, then pull tray 4 to remove it.

[0003] During the process of tray 4 entering and exiting furnace body 1, tray 4 is supported by roller 2. When tray 4 moves, there is a certain amount of friction between it and roller 2. The magnitude of the friction is related to the pressure of tray 4 on roller 2. When tray 4 is completely inside furnace body 1 (e.g. Figure 4 As shown), the tray 4 is supported by more rollers 2. The pressure on each roller 2 is relatively small when the tray 4 moves, resulting in low friction between the tray 4 and each roller 2. As the tray 4 gradually moves outside the furnace door 1, one end of the tray 4 is manually supported, while the other end is supported by rollers 2. The number of rollers 2 supporting the tray 4 gradually decreases (e.g., ...). Figure 3 As shown in the figure, the closer the roller 2 is to the furnace door 3, the greater the pressure it bears, the greater the friction, and the more severe the wear.

[0004] In addition, when the tray 4 enters the furnace body 1, the roller 2 closest to the furnace door 3 is the first to contact the supporting tray 4, and when the tray 4 is removed, the roller 2 closest to the furnace door 3 is the last to leave the tray 4. That is, the roller 2 closest to the furnace door 3 has the longest contact time with the supporting tray 4, and therefore the wear is the most severe.

[0005] It is evident that the wear rates of the various rollers 2 differ, with the rollers 2 closest to the furnace door 3 wearing down rapidly. To mitigate the wear rate of the rollers 2 near the furnace door 3, workshop workers tie towels to them. When the tray 4 enters and exits the furnace door 1, the towels come into direct contact with each other, bearing the friction and thus preventing rapid wear of the rollers 2 near the furnace door 3. Once the towels are worn out, new towels are simply tied on. While this method effectively slows down the wear rate of the rollers 2 near the furnace door 3, the stability of the tied towels is poor, and the operation remains inconvenient. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a baking oven roller mechanism that can effectively slow down the wear rate of the rollers near the oven door.

[0007] To solve the above problems, the technical solution adopted by this utility model is: an oven roller mechanism, including multiple wear-prone rollers and multiple support rollers, wherein isolation members are provided at both ends of the wear-prone rollers.

[0008] The isolation component includes a snap-fit ​​groove, which includes a top plate and a first elastic side plate and a second elastic side plate disposed on both sides of the top plate. A snap-fit ​​cavity is provided between the first elastic side plate and the second elastic side plate. The wearable roller shaft is snapped into the snap-fit ​​cavity, and the snap-fit ​​grooves on adjacent wearable roller shafts are connected.

[0009] Furthermore, the snap-fit ​​grooves on adjacent two grinding roller shafts are detachably connected.

[0010] Furthermore, a first connecting plate is provided on the outer side of the first elastic side plate, and a second connecting plate is provided on the outer side of the second elastic side plate. The first connecting plate is detachably connected to the second connecting plate of the adjacent isolation member.

[0011] Furthermore, the first connecting plate is connected to the second connecting plate of the adjacent spacer by screws.

[0012] Furthermore, the top plate, the first elastic side plate, and the second elastic side plate are integrally formed.

[0013] Furthermore, the top plate, the first elastic side plate, and the second elastic side plate are arc-shaped plates.

[0014] Furthermore, the snap-fit ​​groove is neither a plastic groove nor a metal groove.

[0015] The beneficial effects of this utility model are as follows: the easy-grind roller shaft is a roller shaft close to the oven door. This utility model sets snap-fit ​​grooves at both ends of the easy-grind roller shaft, and the top plate of the snap-fit ​​groove is located above the easy-grind roller shaft. When the tray enters or leaves the oven, the top plate of the snap-fit ​​groove directly contacts the tray, and the snap-fit ​​groove is worn. The easy-grind roller shaft will not contact the tray, thereby effectively alleviating the wear of the easy-grind roller shaft.

[0016] Furthermore, the snap-fit ​​groove engages with the wear-resistant roller shaft without the need for additional connectors, making it very convenient to disassemble, install, and replace the snap-fit ​​groove. Moreover, the snap-fit ​​groove can be directly installed on existing ovens without any additional modifications, resulting in low implementation costs. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] The oven roller mechanism of this utility model, such as Figure 1 and Figure 2 As shown, it includes multiple wear-resistant roller shafts 10 and multiple support roller shafts 11, with isolation members provided at both ends of the wear-resistant roller shafts 10. Figure 1 and Figure 2 Part of the support roller shaft 11 is shown in the figure.

[0024] Among them, the wear-prone roller 10 is the roller close to the oven door, and there are generally 2 to 4 rollers. The remaining rollers are the support rollers 11, which are the rollers that are farther away from the oven door and have a slower wear rate.

[0025] The isolation component includes a snap-fit ​​groove, which includes a top plate 12 and a first elastic side plate 13 and a second elastic side plate 14 disposed on both sides of the top plate 12. A snap-fit ​​cavity is provided between the first elastic side plate 13 and the second elastic side plate 14. The easy-wearing roller shaft 10 is snapped into the snap-fit ​​cavity, and the snap-fit ​​grooves on two adjacent easy-wearing roller shafts 10 are connected.

[0026] The lower end of the snap-fit ​​cavity is open, and its width is slightly smaller than the diameter of the easy-grind roller shaft 10. This ensures that after the easy-grind roller shaft 10 is snapped into the snap-fit ​​cavity, the first elastic side plate 13 and the second elastic side plate 14 will elastically deform and press the easy-grind roller shaft 10 tightly. When installing the snap-fit ​​groove, align the lower end of the snap-fit ​​cavity downwards with the easy-grind roller shaft 10, and then apply a downward thrust to the snap-fit ​​groove to move it downwards, thus snapping the easy-grind roller shaft 10 into the snap-fit ​​cavity. The distance between the snap-fit ​​grooves at both ends of the easy-grind roller shaft 10 is smaller than the width of the tray, ensuring that the tray can be supported by the snap-fit ​​grooves. To ensure effective support for the tray, a snap-fit ​​groove can also be provided in the middle of the easy-grind roller shaft 10.

[0027] Connecting the locking grooves on two adjacent easy-to-wear roller shafts 10 into one unit can prevent the easy-to-wear roller shaft 10 from driving the locking groove to rotate, ensuring that the top plate 12 of the locking groove is always above the easy-to-wear roller shaft 10.

[0028] With the oven roller mechanism of this invention, when the tray enters and exits the oven, the top plate 12 of the locking groove directly contacts the tray, causing wear on the top plate 12. Meanwhile, the wear-prone roller 10 does not contact the tray, thus reducing wear on the wear-prone roller 10 and decreasing the frequency of its maintenance and replacement. After the locking groove is worn, it can be quickly removed and a new locking groove installed.

[0029] In this utility model, the snap-fit ​​groove has a simple structure and adopts a snap-fit ​​installation method. During installation, no other connecting parts are needed to connect the snap-fit ​​groove and the wear-resistant roller shaft 10 into one piece. Disassembly and assembly are very convenient. It can be directly installed on the basis of the existing oven roller shaft, and the implementation cost is low.

[0030] The snap-fit ​​grooves on multiple easy-wearing roller shafts 10 can be integrally formed. Preferably, the snap-fit ​​grooves on two adjacent easy-wearing roller shafts 10 can be detachably connected. Two to four snap-fit ​​grooves can be connected as a whole as needed and then installed onto the easy-wearing roller shaft 10.

[0031] A first connecting plate 15 is provided on the outer side of the first elastic side plate 13, and a second connecting plate 16 is provided on the outer side of the second elastic side plate 14. The first connecting plate 15 is detachably connected to the second connecting plate 16 of the adjacent isolation member. Specifically, the first connecting plate 15 can be connected to the second connecting plate 16 of the adjacent isolation member by screws. There is a gap between the easy-grinding roller shafts 10, and the first connecting plate 15 and the second connecting plate 16 are located in the gap between the easy-grinding roller shafts 10.

[0032] In this utility model, the top plate 12, the first elastic side plate 13, and the second elastic side plate 14 are integrally formed.

[0033] The top plate 12, the first elastic side plate 13, and the second elastic side plate 14 can be flat plates. In a preferred embodiment, the top plate 12, the first elastic side plate 13, and the second elastic side plate 14 are arc-shaped plates. The inner wall of the arc-shaped plate can better fit the easy-to-wear roller shaft 10, increase the contact area with the easy-to-wear roller shaft 10, and improve the stability of the snap-fit ​​groove.

[0034] In this invention, the snap-fit ​​groove is either a plastic groove or a metal groove, and its thickness is about 2mm.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
