DETAILED DESCRIPTION

[0047] The concept, specific structure and generated technical effects of the present application will be described clearly and completely in combination with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments, and other embodiments obtained by those skilled in the art without creative labor based on the embodiments of the present application all belong to the scope of protection of the present application. In addition, all the coupling / connection relations involved in the patent do not mean that the components are directly connected, but means that a better coupling structure can be composed by adding or reducing coupling auxiliary parts according to the specific implementation situation. The various technical features in the present application creation can be interactively combined without mutual contradiction and conflict.

[0048] Referring to Figure 1 , Figure 4 and Figure 5 , a single-sided oven threading device comprises a rail 1, a threading block 3, a threading rod 4, a conveying belt 5 and a conveying belt traction group 6;

[0049] The rail 1 is fixed in position relative to the oven and is arranged on one side of the oven;

[0050] The threading rod 4 is connected with the threading block 3, and is used to fix the base material;

[0051] The threading block 3 is slidably arranged on the guide rail 1 and is fixed on the conveying belt 5;

[0052] The conveying belt traction group 6 is used to slide the conveying belt 5 on the guide rail 1, so as to drive the threading block 3, the threading rod 4 and the base material to move from the entrance of the oven to the exit of the oven.

[0053] In use, the guide rail 1 is fixed on the oven, one end of the base material is overlapped on the threading rod 4 before the entrance of the oven, the device is started, the conveying belt traction group 6 drives the base material to pass through the oven to the exit of the oven, so as to complete the threading work.

[0054] The threading rod 4 for fixing the base material is indirectly slid on the guide rail 1 through the threading block 3, the guide rail 1 is small in size, the contact points between the threading block 3 and the inner wall of the guide rail 1 can be small in friction, and the threading block 3 is more smooth in sliding on the guide rail 1, so that the jamming of the threading block 3 in the guide rail 1 can be reduced.

[0055] In the device, if the base material is broken in the drying and threading process, the operator only needs to pull out the broken base material from both ends of the oven, without opening the oven door, so that the working environment can be improved and the potential risk to the operator's health can be reduced. The guide rail mechanism 1 is designed as a single-sided structure, and considering that the span of the oven usually exceeds 1 meter and the total length exceeds 50 meters, the double-sided guide rail can be jammed or the base material can be broken again in the conveying process due to inconsistent sliding or different transmission.

[0056] As an example, the conveying belt 5 is one of a steel wire rope, a chain, a rope and a belt.

[0057] Specifically, the threading rod 4 is made of aluminum alloy, which is light in weight and has a certain strength, and is not easy to deform when driving the base material, so that the stable threading of the base material can be ensured.

[0058] Specifically, the guide rail 1 is an aluminum square tube, the aluminum square tube is single-sidedly grooved, and the inside is plated with iron fluorine long; while avoiding direct metal friction, sufficient rigidity is provided for the smooth passing of the threading block 3; wherein the threading support rod 7 extends from the groove.

[0059] As an example of a guide rail fixing method, the guide rail 1 is fixed on the oven at a position that the guide rail 1 can be fixed on the inner wall of the oven.

[0060] As an example of a guide rail fixing method, the guide rail 1 can be fixed on the oven by a bracket. Figure 2 、 3The installation mode in the oven is fixed on the tuyere 200 in the oven; as long as the position of the guide rail 1 relative to the oven is unchanged.

[0061] As an example of the connection mode between the belt passing block 3 and the conveying belt 5, the conveying belt 5 is two sections, one end of the conveying belt 5 is fixedly connected with one end of the belt passing block 3, and the other end of the conveying belt 5 is fixedly connected with the other end of the belt passing block 3. Specifically, the belt passing block 3 is characterized by being thin at both ends and wide and bulging in the middle. The two sections of the conveying belt 5 are fixedly connected at both ends of the belt passing block 3. When the belt passing block 3 slides on the guide rail 1, it helps to keep the conveying belt 5 always in the middle of the guide rail 1, reduces the probability of friction between the conveying belt 5 and the inner wall of the guide rail 1 in the process of sliding of the belt passing block 3, and improves the smoothness of the belt pulling.

[0062] As an example of the connection mode between the belt passing block 3 and the conveying belt 5, the conveying belt 5 is a continuous section, the belt passing block 3 is fixed on the conveying belt 5, and the conveying belt 5 passes through the belt passing block 3.

[0063] Referring to Figure 4 , Figure 5 In an embodiment, the two sides of the belt passing block 3 adjacent to the guide rail 1 are provided with rollers 33, the rollers 33 protrude from the side walls of the belt passing block 3, and the rollers 33 are in rolling contact with the inner wall of the guide rail 1. The rollers 33 are used to assist the belt passing block 3 to slide in the guide rail 1, further improving the smoothness of the belt pulling.

[0064] Specifically, the roller 33 is an external threaded bearing.

[0065] Referring to Figure 4 , Figure 5 , Figure 6 In an embodiment, a belt passing support rod 7 is further included, one end of the belt passing support rod 7 is detachably connected with the belt passing block 3, and the other end of the belt passing support rod 7 is hingedly connected with the belt passing rod 4.

[0066] A side groove 11 extending from the entrance of the oven to the exit of the oven is formed in the side edge of the guide rail 1, and the support rod 7 and the belt passing rod 4 partially pass out to the oven through the side groove 11;

The belt passing support rod 7 is used to fix the position of the belt passing support rod 7 on the belt passing block 3.

[0068] The belt passing support rod 7, the belt passing block 3, and the belt passing rod 4 form a stable triangular structure, reducing the probability of deformation of the belt passing rod 4 in the process of belt passing and belt pulling, and improving the stability of the belt passing rod 4.

[0069] Referring to Figure 5 , specifically, the opening direction of the hook-shaped strip threading rod 4 is towards the side of the strip threading support rod 7, reducing the probability of the strip threading rod 4 falling off the strip threading block 3.
