Description

Technical Field

[0001] This utility model belongs to the field of food machinery, and in particular relates to a device for turning over strip-shaped materials. Background Technology

[0002] The food preparation process mainly involves mixing, heating, and melting raw materials to form a viscous material, which is then extruded through an extruder to form sheet-like sugar cakes. These sugar cakes are then conveyed forward by a conveyor belt. When freshly formed, the sugar cakes are generally quite viscous. While being conveyed, they undergo a series of cooling processes to harden their outer surface. To shape the finished product, the sugar cakes are further processed into strips. Some products can also be directly extruded into strips using molds. These strips typically lie flat on the conveyor belt and are conveyed forward to a cutting machine for slicing. To maximize production efficiency, the conveyor belt operates at a relatively high speed. Because the sugar cakes or strips lie flat on the conveyor belt, the back of the material tends to adhere to the belt surface due to the relatively long contact time. Because the back of the material adheres relatively firmly to the conveyor belt surface, pitting will occur on the material surface during the peeling process. This affects the appearance of the finished product and also causes particulate material to adhere to the conveyor belt surface, requiring frequent cleaning. In some food products, powder needs to be adhered to the surface to enrich the texture and appearance of the finished product. To improve the adhesion of the powder to the material surface, the surface can be moistened or melted at high temperatures. Therefore, after such surface treatment, the adhesion between the material and the conveyor belt will also increase. However, when conveying such materials via the conveyor belt, the aforementioned problems are also likely to occur. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a strip material turning device, which can change the surface of the strip material in contact with the conveyor belt, and effectively reduce the impact on production when the material is separated from the conveyor belt.

[0004] To solve the aforementioned technical problem, the present invention provides the following technical solution: a strip-shaped material turning device, comprising several segmented conveyor belts connected to a drive roller, a motor connected to the drive roller, and the conveyor belts conveying the flat strip-shaped material under the drive of the drive roller. These conveyor belts are connected in series in the forward direction of the strip-shaped material. The device is characterized by further including a turning structure disposed between the conveyor belts. The turning structure has several slits, which are positioned corresponding to the location of the strip-shaped material. The width of the slit is less than the width of the strip-shaped material but greater than its thickness, and one strip-shaped material is used to pass through one slit.

[0005] During the preparation process, the strip-shaped material is continuously prepared. The initial end of the strip-shaped material is pre-twisted and passed through a slit, so that the original front side of the strip-shaped material is flipped onto the surface of the downstream conveyor belt, while the original back side of the strip-shaped material is separated from the surface of the downstream conveyor belt, thus enabling the strip-shaped material to be flipped on the downstream conveyor belt.

[0006] Preferably, the slits are arranged in parallel along a direction perpendicular to the direction of travel of the strip material. This allows these flipping structures to be mounted on a single unit, thus facilitating the manufacture and installation of the flipping structures.

[0007] Preferably, the flipping structure includes a plurality of vertically arranged limiting posts, and the slit is formed between two adjacent limiting posts. Using limiting posts as the flipping structure is simple and easy to install. In particular, when strip-shaped materials slide over the cylindrical limiting posts, the resistance is small, which facilitates the smooth flipping of the strip-shaped materials.

[0008] Preferably, the system also includes a transition conveyor belt for the passage of the strip-shaped material. The width of the transition conveyor belt corresponds to the width of the conveyor belt. The transition conveyor belt is located upstream of the flipping structure and is positioned close to the flipping structure. This separately installed transition conveyor belt provides power for the forward movement of the strip-shaped material, enabling it to pass smoothly through the narrow slit.

[0009] Preferably, the length of the transition conveyor belt is less than the length of the conveyor belt. The smooth passage of strip-shaped materials through the narrow gap can be ensured by modifying the structure of the transition conveyor belt, such as increasing its conveying surface or its speed.

[0010] Preferably, a moving material-straining structure is provided at a position relative to the transition conveyor belt. The material-straining structure acts on the transition conveyor belt, causing the portion of the transition conveyor belt that conveys the strip-shaped material to sway. The swaying of the transition conveyor belt by the material-straining structure helps to straighten the changes in the state of the strip-shaped material, facilitating its smooth passage through the narrow gap.

[0011] Preferably, the material handling structure includes a rotating roller disposed on the back side of the transition conveyor belt. The rotating roller has several protruding structures, which cause the transition conveyor belt to sway by contacting the back side of the transition conveyor belt during rotation. This material handling structure can adapt well to the action on the transition conveyor belt, resulting in effective swaying of the transition conveyor belt.

[0012] Preferably, the protruding structure is a U-shaped material guide bar, which is positioned axially on the rotating roller. The material guide bar is generally made of stainless steel, and its protruding structure is simple and easy to install.

[0013] Preferably, the back of the transition conveyor belt is provided with several support rods, which are arranged along the forward direction of the transition conveyor belt. The transition conveyor belt is slidably supported on the support rods, which are located on the upstream side of the material handling structure. The support rods effectively accommodate the swaying of the transition conveyor belt, resulting in good operational stability.

[0014] Therefore, the beneficial effects of this utility model are as follows: By setting the aforementioned flipping structure between the conveyor belts, the strip-shaped material can be flipped to prevent it from being in contact with the conveyor belt for too long. During the cooling process, the strip-shaped material adheres firmly to the conveyor belt, which would damage its surface when peeled away. The flipping structure allows the front side of the strip-shaped material to be in contact with the downstream conveyor belt. Since the front side of the strip-shaped material has already hardened to a certain extent on the upstream conveyor belt, it is less likely to stick to the downstream conveyor belt, thus effectively ensuring the appearance of the strip-shaped material and facilitating the cleaning of the conveyor belt surface.

Detailed Implementation

[0019] Referring to the accompanying drawings, this strip-shaped material turning device is used in the food machinery field to turn strip-shaped materials over, so as to prevent the strip-shaped materials from sticking to the surface of the conveyor belt 1 for a long time, which would seriously affect the appearance and cause poor cleanliness of the conveyor belt 1 surface when the strip-shaped materials are separated from the conveyor belt 1.

[0020] The structure of this turning device includes several segmented conveyor belts 1, each conveyor belt 1 being a closed-loop structure connected to a pair of drive rollers. A motor 2 is connected to the drive rollers, and the conveyor belts 1, driven by the drive rollers, transport the flat strip-shaped material. These conveyor belts 1 are connected in series in the forward direction of the strip-shaped material, and these conveyor belts 1 transport the strip-shaped material in the same direction, allowing the strip-shaped material to move forward continuously.

[0021] The flipping device also includes a flipping structure, which is positioned between two adjacent conveyor belts 1. The flipping structure has several slits that are open in the forward direction of the strip-shaped material. These slits are positioned corresponding to the location of the strip-shaped material; the width of the slit is less than the width of the strip-shaped material but greater than its thickness. One strip-shaped material passes through one slit. Before passing through the slit, the strip-shaped material undergoes a twisting change, causing its front side on the upstream conveyor belt 1 to adhere to the surface of the downstream conveyor belt 1, while its back side on the upstream side faces outwards on the downstream side.

[0022] The slits are arranged in parallel along the direction perpendicular to the advancing direction of the strip material. Figure 1 The diagram shows that the flipping structure includes several vertically arranged limiting posts 3, with slits formed between adjacent limiting posts 3. These limiting posts 3 are vertically fixed to a mounting rod 4, which is arranged perpendicular to the forward direction of the strip material. A through mounting groove is provided along the length of the mounting rod 4. The lower end of each limiting post 3 is a reduced-diameter connecting post that passes through the mounting groove. A fixing nut is threaded onto the connecting post at the back of the mounting rod 4, thus achieving the fixed connection between the limiting posts 3 and the mounting rod 4. The spacing between these limiting posts 3 is adjustable to accommodate flipping requirements for strip materials of different thicknesses. When manually flipping the strip material, the twisted strip material can be inserted from the upper side of the limiting posts 3 into the gaps between them. The flipping structure can also be a flipping panel, with slits provided on the panel, and the strip material vertically and intermittently passing through the slits.

[0023] A transition conveyor belt 5 is also provided upstream of the flipping structure, and is located close to the flipping structure. The transition conveyor belt 5 has an independent power mechanism. Figure 3 As shown, the transition conveyor belt 5 is movably mounted on the frame 10, and the motor 2 on the frame 10 provides power for the movement of the transition conveyor belt 5 through the drive roller. The transition conveyor belt 5 drives the strip-shaped material forward towards the flipping structure, and the width of the transition conveyor belt 5 is equal to the width of the conveyor belt 1. The size of the transition conveyor belt 5 is relatively small, and the length of the transition conveyor belt 5 is less than the length of the conveyor belt 1.

[0024] A moving material handling structure is located relative to the transition conveyor belt 5. This structure acts on the transition conveyor belt 5, causing the portion of the belt conveying strip-shaped materials to sway. The material handling structure includes a rotating roller 6, which is positioned along the width of the transition conveyor belt 5 and located on its back side. The rotating roller 6 has several protruding structures. During rotation, these protruding structures abut against the back side of the transition conveyor belt 5, causing it to sway. The protruding structures are U-shaped material handling rods 7, positioned axially on the rotating roller 6. Several material handling rods 7 are evenly distributed around the circumference of the rotating roller 6.

[0025] In order to accommodate the swaying of the transition conveyor belt 5, Figure 3 As shown, two connecting rods 9 are bridged on the frame 10 along the width direction of the transition conveyor belt 5. Several support rods 8 are vertically fixed to the two connecting rods 9. The support rods 8 are located on the back side of the transition conveyor belt 5, and the transition conveyor belt 5 is slidably supported on the support rods 8. These support rods 8 are arranged along the forward direction of the transition conveyor belt 5. In order to ensure the smooth movement of the transition conveyor belt 5 on the support rods 8, both ends of the support rods 8 are slightly curved downwards. Figure 3 As shown, in the forward direction of the strip material, the support rod 8 is located upstream of the rotating roller 6. Several rollers 11 are provided on both sides of the frame 10, arranged along the width of the transition conveyor belt 5. These rollers 11 abut against the back of the transition conveyor belt 5 to provide rolling support for the transition conveyor belt 5.
