Description

Technical Field

[0001] The invention relates to the technical field of sprocket block processing, in particular to a sprocket block assembling device for a spiral quick-freezing machine. Background Art

[0002] The spiral quick freezer is an energy-saving quick freezing equipment with compact structure, wide application, small footprint and large freezing capacity. It has large freezing capacity. Due to the double drum structure, the characteristics of the spiral quick freezer are more fully utilized. A large number of machined parts are used to eliminate the welding deformation caused by welded parts, the transmission cumulative deviation caused by welding stress concentration, and the transmission inconsistency. The spiral quick freezer is the preferred model for domestic and foreign food processing companies for quick freezing of frozen products such as meat with large thickness, large volume and high feed temperature. The scope of application: prepared food, ice cream, pastry, cut meat and poultry, aquatic products, fried food, small packaged food, etc.

[0003] After searching, Chinese patent number CN 113634976 B discloses a sprocket block assembly device for a spiral quick-freezing machine, including a base plate, a support frame is fixedly connected to the upper surface of the base plate, and a clamp for clamping the sprocket body is rotatably connected to the upper end of the support frame. The present invention sets a positioning mechanism, and when the user assembles the sprocket block and the sprocket body, the user can use the limit rod to limit the sprocket block, and use the guide wheel to drive the sprocket body to rotate until the positioning rod passes through the through holes on the chain body and the sprocket block, so as to achieve accurate positioning of the first sprocket block, and also fix the sprocket block and the sprocket body so that the sprocket block and the sprocket body are relatively stationary, thereby completing welding and fixing, and the sprocket block is accurately positioned, which can effectively avoid the situation where the tooth pitch on the sprocket is different in size, prevent the chain from being damaged, and improve the transmission efficiency of the sprocket, and reduce the kinetic energy loss during the transmission process.

[0004] However, the above prior art still has the following problems:

[0005] Although the sprocket block and the sprocket body are fixed by setting a positioning mechanism, so that the sprocket block and the sprocket body are relatively stationary, thereby completing the welding fixation, and the sprocket block is accurately positioned, which can effectively avoid the situation where the tooth pitch on the sprocket is different in size, prevent the chain from being damaged, and improve the transmission efficiency of the sprocket, and reduce the kinetic energy loss during the transmission process;

[0006] However, when the sprocket block is welded and installed by the sprocket block assembly device for the spiral quick freezer, debris and welds are generated during the welding process. The above-mentioned sprocket block assembly device for the spiral quick freezer cannot grind the welds and cannot collect and clean the debris, resulting in the debris being stuck between the sprocket block and the sprocket body after the sprocket block is installed, affecting the use of the sprocket block. At the same time, the presence of the weld causes bulges to form on the surfaces of the sprocket block and the sprocket body, which may cause the sprocket body or the installation position to be offset when the sprocket block and the sprocket body are installed, affecting the transmission accuracy of the sprocket block and the sprocket body.

[0007] Therefore, the present invention provides a sprocket block assembly device for a spiral quick-freezing machine to solve the above-mentioned problems. Summary of the invention
