Description

Technical Field

[0001] The invention relates to a biscuit finishing, pouring and spreading integrated production device. Background Art

[0002] A type of biscuit that is currently popular on the market has chocolate paste poured on the surface of the biscuit, and nut particles are embedded in the chocolate paste, which greatly enriches the appearance and taste of the biscuit.

[0003] The actual production process of this type of biscuits is more complicated than that of regular biscuits. In addition to the making and shaping of the biscuit body, it also requires two subsequent steps: pouring chocolate paste and sprinkling nut particles.

[0004] At present, the pouring and spreading of the above-mentioned biscuits are carried out in separate processes in the industry. The transportation of raw materials between multiple processes relies on manual connection, which is not conducive to continuous production and has low efficiency. In addition, the following problems are encountered in the actual production process:

[0005] 1) In order to avoid the problem of front and rear biscuits sticking together due to continuous pouring of chocolate slurry, the existing pouring machines perform pouring actions intermittently. For this reason, the pouring machine needs to sort the biscuits before pouring, sorting the biscuits into neat vertical and horizontal rows, and the biscuits in the front and rear rows should be evenly spaced, so that the pouring machine can accurately pour the chocolate slurry onto the surface of each row of biscuits. However, the current sorting process is all done manually, which is labor-intensive and inefficient. In addition, when the output is large and the working hours are long, workers often cannot guarantee the discharge quality of the biscuits. At the same time, multiple batches of workers are often arranged to work in shifts, which also increases the labor costs of the enterprise.

[0006] 2) Sprinkling is usually done manually, which results in poor uniformity of the distribution of nut particles on the surface of the biscuit chocolate and high labor intensity for workers. Of course, there are also some automatic spreading mechanisms in the industry, but these mechanisms can only mechanically spread the nut particles on the surface of the biscuit along a certain trajectory, and cannot further spread the nut particles evenly on the surface of the biscuit, so the final effect is still not good.

[0007] Therefore, in summary, the industry is currently in urgent need of a production device that can integrate biscuit sorting, pouring and spreading in one to solve the existing problems of low production efficiency and high labor costs. Summary of the invention

[0008] The purpose of the present invention is to provide a biscuit sorting, pouring and spreading integrated production device, which can improve production efficiency and reduce labor costs.

[0020] The working principle of the present invention is as follows:

[0021] 1) Place the biscuits with the same or similar width specifications (the shapes and lengths can be different) formed in the previous forming process on the sorting conveyor belt and convey them. During the conveying process, these biscuits are sorted into multiple neat rows by the row-straightening mechanism and continue to be conveyed.

[0022] 2) Then, under the action of the biscuit lifting mechanism, a row of biscuits reaching the pallet at the end of the finishing conveyor belt is lifted to above the front end of the pouring conveyor belt;

[0023] 3) Under the action of the pulling and aligning mechanism, the row of biscuits on the lifting tray is pulled into a row and moved to the pouring conveyor belt; under the control of the PLC controller, the rows of biscuits are evenly spaced and transported forward along the pouring conveyor belt;

Compared with the current manual operation method, it greatly improves the production efficiency and production quality, and because it can replace the workload of multiple batches of workers, it also reduces labor costs.

[0029] 2.
