Description

Technical Field

[0001] The utility model belongs to the technical field of food production, and in particular relates to a rice crust conveying device. Background Art

[0002] Patent CN110024957A previously applied for by the applicant discloses a method for preparing rice crust, which uses a steel conveyor belt to support and transport materials. The steel conveyor belt is relatively thin and has good thermal conductivity, but poor thermal insulation effect and is sensitive to changes in the heat source. It is necessary to improve the heat source stability and thermal insulation performance of the entire conveying path in order to obtain a product with stable quality, which cannot meet the needs of optimizing the processing technology.

[0003] Prior art CN217675089U (Document 1) discloses a conveyor for a rice cracker machine. Its background technology discloses a technical solution in which a rice cracker machine uses a chain drive to drive the rice cracker baking trays. Regarding this solution, the following description states, "With this transmission method, as the chain rotates, the baking trays flip with it, causing changes in the bottom and top of the rice cracker, thereby affecting the appearance, texture, and quality of the rice cracker." To address this technical problem, Document 1 provides upper and lower tracks that pass through a tunnel furnace. Multiple baking trays are closely arranged on each track. The lower track's ends are each one baking tray's length longer than those of the upper track. Vertical baking tray lifting devices are installed at the bottom of the frame at both ends of the lower track. These lifting devices transfer baking trays at the ends of the upper / lower track to the lower / upper track, allowing the baking trays to be transported between the upper and lower tracks, thereby achieving a reciprocating effect without flipping the baking trays. This solution completely eliminates the existing conveyor mechanism and requires the addition of an additional lifting device for the baking trays, resulting in significant modification costs for the production equipment. It can also be learned from the records in the background technology of document 1 that in this solution, the rice crust is placed in the baking tray and the rice crust will not fall off when the baking tray is turned over. In this way, the operator cannot directly observe the baking status of the rice crust, and cannot adjust the baking conditions in time to ensure the stability of product quality. Utility Model Content

[0004] The purpose of the utility model is to provide a rice crust conveying device, which can reliably convey rice crust blocks and continuously and stably transfer heat to the rice crust blocks.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a rice crust conveying device, a unit plate for supporting the rice crust is installed on the conveying chain, and the unit plate rotates and displaces around the driving wheel and the driven wheel along with the conveying chain under the drive of the driving wheel.

[0006] Two parallel and spaced apart conveyor chains 11 are wound around a driving wheel 12 and a driven wheel 13 , and both side edges of the unit plate 10 are connected to the two conveyor chains 11 respectively.

[0007] Compared with the prior art, the present invention has the following technical effects: the unit plates have a certain thickness, which, compared with the steel conveyor belts in the prior art, have better thermal insulation performance and slower heat dissipation. This allows the unit plates to continuously transfer heat to the rice crust materials spread thereon after being heated, thereby maintaining the continuous heating state of the rice crust materials during the conveying path and avoiding the degradation of product quality caused by the middle of the heating state. In addition, the top of the rice crust materials spread on the unit plates is exposed, which facilitates the evaporation and discharge of moisture in the rice crust materials, thereby accelerating the hardening and coking of the rice crust materials, allowing the rice crust materials to be quickly shaped, thereby improving the production and processing efficiency of the rice crust.

[0018] The specific implementation of the present invention will be further described in detail below through description of embodiments in conjunction with the accompanying drawings.

[0019] A rice crust conveying device, as shown in the following Figure 1As shown, it includes a unit plate 10 for supporting the rice crust material, and a conveyor chain 11 wound around a driving wheel 12 and a driven wheel 13. The unit plate 10 is fixedly mounted on the conveyor chain 11, and rotates and displaces around the driving wheel 12 and the driven wheel 13 along with the conveyor chain 11 under the drive of the driving wheel 12. The unit plate has a certain thickness. Compared with the steel conveyor belt in the prior art, it has better thermal insulation performance and slower heat dissipation. After being heated, the unit plate 10 can continuously heat the rice crust material spread thereon, thereby maintaining the continuous heating state of the rice crust material in the conveying path. In addition, the top of the rice crust material spread on the unit plate 10 is exposed, which facilitates the evaporation and discharge of moisture in the rice crust material, thereby accelerating the hardening and coking of the rice crust material, so that the rice crust material can be quickly shaped.

[0020] In this embodiment, the heating source is located below the unit plate 10. To ensure the stability and reliability of the unit plate 10, the unit plate 10 is made of food-grade metal. Furthermore, aluminum plate can be selected for its lightness and fast heat conduction. To ensure the thermal insulation effect of the unit plate 10, the unit plate 10 should be thicker than 5mm.

[0021] The preferred solution is as follows Figure 1-3 As shown, two parallel and spaced conveyor chains 11 are wound around a driving wheel 12 and a driven wheel 13, and the two side edges of the unit plate 10 are respectively connected to the two conveyor chains 11. The two side edges of the unit plate 10 are reliably supported, thereby stably maintaining the material conveying posture.

[0022] In this embodiment, the connection structure between the unit plate 10 and the conveyor chain 11 is shown in the attached figure. Figure 5 、 7 As shown in Figures 8 and 9, the side panel edges of the unit plate 10 are connected to the conveyor chain 11 through the angle connector 20. The main plate 21 of the angle connector 20 is connected to the link shaft 111, and the flat plate 22 of the angle connector 20 is connected to the edge of the unit plate 10. To facilitate the positioning and installation of the angle connector 20 and the unit plate 10, a shallow groove 101 is provided on the bottom plate surface of the side panel edge of the unit plate 10, and the flat plate 22 is embedded in the shallow groove 101. In this embodiment, a boss 102 protruding toward the side where the conveyor chain 11 is located is provided on the side panel edge of the unit plate 10, and the projection of the angle connector 20 in the direction perpendicular to the plate surface of the unit plate 10 is located on the inner side of the boss 102. The boss 102 can cover the angle connector 20 or the connection position between the angle connector 20 and the conveyor chain 11. On the one hand, it allows the connection position between the angle connector 20 and the unit plate 10 to be further externalized, thereby reserving installation space for the components below the unit plate 10. On the other hand, it can prevent materials, dust particles or water droplets from falling into the connection gap of the angle connector 20, thereby ensuring a stable and reliable connection between the unit plate 10 and the conveyor chain 11.

[0023] In this embodiment, the unit plate 10 is a rectangular plate, the length direction of the unit plate 10 is consistent with the wheel core direction of the driving wheel 12, the width direction of the plate is perpendicular to its length direction, and the middle part of the unit plate 10 in the width direction is connected to the conveyor chain 11. Figure 7 、 8 As shown, the middle portion of the side panel edge of the unit panel 10 is connected to the angle connector 20 by screws.

[0024] When the distance between the two conveyor chains 11 is large, that is, the size of the unit plate 10 perpendicular to the displacement conveying direction is large, in order to ensure the stable and reliable displacement of the unit plate 10, as shown in the attached Figure 2 、 3 As shown in FIG4 , a support wheel 104 can be fixed on the back of the unit plate 10, and a support seat 42 can be correspondingly provided on the crossbeam 41 of the frame 40. The support wheel 104 and the support seat 42 form a rolling fit to provide support for the unit plate 10 while ensuring smooth displacement of the unit plate 10. Figure 3 As shown, the support wheel 104 is arranged at the middle position of the two side plate edges where the unit plate 10 is connected to the conveyor chain 11.

[0025] On the conveying path of the unit plate 10, when the rice crust raw material needs to be processed, in order to further reliably support the unit plate 10, a support roller 30 can be set on the back of the unit plate 10. Figure 6 As shown, a grinding wheel is installed above the unit plate 10 at the upper segment of the conveyor chain 11. To maintain the posture of the unit plate 10 in this processing position and ensure processing quality, the bottom surface of the unit plate 10 forms a rolling fit with the support roller 30. The support roller 30 is mounted on the crossbeam 41 of the frame 40 by a roller seat 31. The roller core of the support roller 30 is parallel to the wheel core of the driving wheel 12. The key is to make the roller core of the support roller 30 parallel to the bottom surface of the unit plate 10, thereby ensuring the vertical support effect of the support roller 30 on the unit plate 10.

[0026] The adjacent edges of the adjacent unit plates 10 on the upper chain segment of the conveyor chain 11 are spaced apart, and the front and / or rear edges of the unit plates 10 are transitionally connected to the bottom surface 105 by chamfered surfaces 103, which are inclined or curved. This not only facilitates the rotation of the unit plates 10 at the driving and driven pulleys 12 and 13, but also prevents the rice crust raw materials from dripping or falling through the gaps between adjacent unit plates 10, ensuring continuous and stable production and processing of the rice crust.
