[0033] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0034] Embodiment 1

[0035] The conveyor belt includes a connecting rod and a transmission module 1, and there are multiple connecting rods and transmission modules 1, and multiple transmission modules 1 can be connected in series through multiple connecting rods to form a belt-like structure, i.e., a conveyor belt. Among them, a first through hole 11 and a second through hole 12 are provided on the transmission module 1. After multiple transmission modules 1 are arranged in sequence along the length direction of the vertical connecting rod, a connecting rod is simultaneously inserted into the first through hole 11 of a transmission module 1 and the second through hole 12 of another transmission module 1, so that multiple transmission modules are connected in series to form a belt-like structure, and in order to realize the turning function of the conveyor belt applied to the spiral conveying equipment, at least the second through hole 12 is a strip hole. This structure of the conveyor belt is a conventional structure in the art and will not be described in detail here.

[0036] like Figure 1 As shown, the modular spiral conveyor provided in this embodiment is designed to increase the relative fixed speed of the connecting rod and the transmission module 1, that is, to improve the assembly efficiency of the conveyor belt, while reducing the production cost of the conveyor belt. The transmission module 1 is also provided with a third through hole 13 at the two ends 103 in the length direction of the connecting rod, but the cross-sectional area of ​​the third through hole 13 is s1, the cross-sectional area of ​​the connecting rod is s2, and the overlapping area of ​​the third through hole 13 and the first through hole 11 is s0, s0<s2<s1, that is, the third through hole 13 and the first through hole 11 are eccentrically arranged. In specific implementation, the connecting rod is a plastic connecting rod so that it has a certain degree of elastic deformation, so that the staff can rely on external force to deform the connecting rod, and pass through the third through hole 13 and insert it into the first through hole 11. During the use of the conveyor belt, the connecting rod is protected by the transmission module 1 and will not be subjected to external forces, and the overlapping area of ​​the first through hole 11 and the third through hole 13 in the length direction of the connecting rod is smaller than the cross-sectional area of ​​the connecting rod, so the two ends of the connecting rod will not be able to pass through the third through hole 13 independently, thereby achieving relative fixation between the connecting rod and the transmission module 1 and ensuring the connection stability of the conveyor belt. Preferably, the third through hole 13 is a round hole or an elliptical hole.

[0037] Optionally, in this embodiment, the first through hole 11 is an elliptical hole, and the major axis diameter of the first through hole 11 is smaller than the length of the second through hole 12. Compared with setting the first through hole 11 as a circular hole, the connecting rod has greater freedom of movement in the elliptical hole, which can effectively reduce the turning radius of the conveyor belt. In addition, the gap between the connecting rod and the elliptical hole is larger, which is also convenient for subsequent cleaning of the connecting rod.

[0038] Furthermore, in the length direction of the connecting rod, disassembly holes 14 are also provided on the two ends 103 of the transmission module 1. The disassembly holes 14 penetrate in the thickness direction of the transmission module 1, and the disassembly holes 14 are also connected with the third through holes 13 and the first through holes 11 on both sides thereof. Since the connecting rod can pass through the first through hole 11 and the third through hole 13 at the same time only when it is deformed, when removing the connecting rod from the transmission module 1, the staff can insert flat-mouthed pliers from the through disassembly holes 14, use the flat-mouthed pliers to bend the connecting rod to one side, so that the connecting rod partly extends out of the third through hole 13, and then pull the connecting rod from the outside of the transmission module 1.

[0039] Optionally, the transmission module 1 includes a connecting rib 104 and connecting teeth 105 disposed on both sides of the connecting rib 104, and the extension length of the transmission module 1 is determined by the number of its connecting teeth 105. In order to enhance the transmission strength of the transmission module 1, along the extension direction of the connecting rib 104, i.e., the length direction of the connecting rod, the width of the connecting teeth 105 of the transmission modules 1 on both sides is a1, and the width of the connecting teeth 105 of the transmission module 1 in the middle is a2, and a1<a2. Since the tooth pitch of two adjacent connecting teeth 105 of the transmission modules 1 on both sides is equal to the tooth pitch of two adjacent connecting teeth 105 of the transmission module 1 in the middle, under the same length, the transmission modules 1 on both sides will have more connecting teeth 105 than the transmission module 1 in the middle, which can distribute the torque generated by the conveyor belt during the transmission process to reduce damage to the transmission modules 1 on both sides.

[0040] Optionally, a chamfer is provided at the connection between the connecting rib 104 and the connecting tooth 105, and a chamfer is provided at each corner of each connecting tooth 105. This can not only avoid scratching the staff during installation, but also increase the depth of the gap between the connecting tooth 105 of one transmission module 1 and the connecting tooth 105 of an adjacent transmission module 1, thereby reducing the turning radius of the conveyor belt. The chamfer also reduces the contact area between the connecting rod and the transmission module 1, which is convenient for flushing the connecting rod.

[0041] Furthermore, in this embodiment, the end 103 of each transmission module 1 has abutment surfaces that can respectively abut two adjacent transmission modules 1, and in the length direction of the vertical connecting rod, one abutment surface close to the middle of the transmission module 1 is an inclined surface 1031. The setting of the inclined surface 1031 can not only ensure the strength of the end 103, that is, retain part of the connecting ribs 104 of the end 103, but also provide a larger space for the abutment of the ends 103 of two adjacent transmission modules 1, so as to reduce the turning radius of the conveyor belt.

[0042] Optionally, because the conveyor belt needs to move on the spiral conveying device, part of the conveyor belt will be distributed in a fan shape during the movement, that is, there may be extrusion or interference between adjacent transmission modules 1 near the fan core. To solve this problem, a transmission protrusion 15 is set on the transmission module 1. When the conveyor belt moves along a straight line, there is a gap between adjacent transmission modules 1. When the conveyor belt moves in a fan shape, adjacent transmission modules 1 partially abut. At this time, the transmission protrusion 15 on one transmission module 1 will press against another transmission module 1, and on the basis of the aforementioned inclined surface 1031, the transmission protrusion 15 of one transmission module 1 will press against the inclined surface 1031 of another transmission module 1. The setting of the transmission protrusion 15 allows two adjacent transmission modules 1 to maintain a certain distance when abutting to avoid wear between the transmission modules 1. In addition, the setting of the transmission protrusion 15 can also adjust the turning radius of the conveyor belt. The higher the height of the transmission protrusion 15, the larger the turning radius of the conveyor belt will be. Of course, this also corresponds to the need for the drive structure to have a larger diameter. Changing the height of the transmission protrusion 15 can make the conveyor belt adapt to different drive structures.

[0043] Optionally, conveyor belts are often used in fields such as food processing. Therefore, in order to improve the ventilation and heat dissipation efficiency of materials placed on the conveyor belt, a plurality of air holes are also provided on the transmission module 1.

[0044] Embodiment 2

[0045] like Figure 3 and Figure 4 As shown, the modular spiral conveyor belt provided in this embodiment is different from the modular spiral conveyor belt in the first embodiment in that:

[0046] In order to prevent the material on the conveyor belt from falling off during the spiral conveying process, the transmission module 1 is also provided with a baffle 16. Specifically, the transmission module 1 has a first surface 101 and a second surface 102 opposite to each other along its thickness direction, wherein the first surface 101 is a working surface, and the material is placed on the working surface during the conveying process, and the baffle 16 is also provided on the working surface.

[0047] Optionally, in order to ensure that the area for placing materials is as large as possible, at least two groups of baffles 16 are provided, and the two groups of baffles 16 are provided on both sides of the transmission module 1 in the length direction of the connecting rod. In this embodiment, the baffle 16 is an S-shaped structure, that is, the baffle 16 is provided on the two ends 103 of the transmission module 1 according to the specific shape of the transmission module 1. In addition, the transmission module 1 is made of plastic material, and the transmission module 1 with the baffle 16 can be integrally manufactured during production, which not only reduces the subsequent fixing process of the baffle 16 on the transmission module 1, but also further enhances the structural strength of the corner of the inclined surface 1031 of the end 103 through the integral setting of the baffle 16 and the end 103. Because the corner of the inclined surface 1031 is subjected to the greatest force during the turning process of the conveyor belt, it is most likely to be damaged, and ensuring its strength can effectively enhance the service life of the conveyor belt.

[0048] In addition, the rest of the structure of the modular spiral conveyor belt provided in this embodiment is the same as that of the modular spiral conveyor belt in the first embodiment, and will not be described again here.

[0049] Embodiment 3

[0050] like Figure 5 and Figure 6 As shown, the modular spiral conveyor belt provided in this embodiment is different from the modular spiral conveyor belt in the second embodiment in that:

[0051] The transmission module 1 is also provided with a lever 17, which is used to cooperate with the rotating hub of the screw conveyor device, so that the transmission mode of the conveyor belt can be changed from friction transmission to direct drive transmission, that is, the rotating hub drives the lever 17 to drive the conveyor belt. In the length direction of the connecting rod, at least one end of the transmission module 1 is provided with a lever 17, wherein Figure 6 As shown, the lever 17 is only provided at one end of the transmission module 1. Figure 5 As shown, levers 17 are provided at both ends of the transmission module 1 .

[0052] Optionally, the lever 17 may be disposed on the first surface 101 of the transmission module 1 or on the second surface 102 of the transmission module 1. Figure 5 and Figure 6 As shown, when the lever 17 is disposed on the first surface 101, the length direction of the lever 17 is parallel to the length direction of the connecting rod, and one end of the lever 17 is connected to the baffle 16, while the other end of the lever 17 can abut against the rotating hub when the conveyor belt is in use. The connection between the lever 17 and the baffle 16 can also enhance the structural strength of the lever 17, reduce the risk of the lever 17 being broken during the process of being moved by the rotating hub, and make the force applied by the rotating hub on the lever 17 further evenly transmitted to the body of the transmission module 1 through the baffle 16, so that the overall force of the conveyor belt is evenly applied.

[0053] Optionally, when the lever 17 is disposed on the first surface 101, a reinforcing rib 18 is further disposed on the first surface 101 of the transmission module 1, and two ends of the reinforcing rib 18 are respectively connected to the lever 17 and the baffle 16 located on the first surface 101, which can further enhance the connection strength between the lever 17 and the baffle 16.

[0054] In addition, the rest of the structure of the modular spiral conveyor belt provided in this embodiment is the same as that of the modular spiral conveyor belt in the second embodiment, and will not be described again here.

[0055] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention.
