Description

Technical Field

[0001] The utility model relates to the technical field of fluid transmission, in particular to a buffer. Background Art

[0002] Existing multi-head perfusion product technology, such as the perfusion product technology that can simultaneously perfuse pastry ingredients in food processing, includes the process of continuous material transmission to several perfusion heads and the perfusion process of the perfusion heads. The continuous material transmission is a continuous and stable transmission of flow rate and transmission pressure, while the perfusion process of the perfusion head is a pulse perfusion process, with a very momentary interruption in the middle to achieve the effect of continuous multi-point perfusion. During the momentary interruption, the flow rate of the perfusion process of the perfusion head will not match the flow rate of the continuous material transmission to several perfusion heads, so that the material in the pipeline of the continuous material transmission to several perfusion heads will increase in pressure due to the momentary retention of the material, resulting in unstable perfusion pressure in the perfusion process of the perfusion head, thereby affecting the instability of the quantity of the perfused product, and then affecting the quality of the product. Summary of the invention

[0003] The purpose of the invention of the utility model is to provide a buffer which can overcome one or more of the above-mentioned shortcomings and can ensure the stability of the filling pressure during the filling process of the filling head, so as to ensure the stability of the quality of the filled product.

[0004] The utility model buffer is implemented as follows: it includes a buffer body whose one end is connected to a material outlet for continuously conveying materials to several filling heads, and the other end is connected to a material inlet for the filling head during the filling process. The buffer body includes a metal tube and a rubber tube arranged in the metal tube. Flanges are arranged at both ends of the metal tube. A recess is arranged in the middle of the end face of the flange, and an annular groove is arranged on the recess. An annular flange protruding from the outer side is arranged at both ends of the rubber tube. The annular flange rests on the recess of the end face of the corresponding flange. The thickness of the annular flange is greater than the depth of the recess, so that the annular flange protrudes out of the recess. The outer diameter of the rubber tube is smaller than the inner diameter of the metal tube, so that a buffer space is formed between the rubber tube and the metal tube. The body of the metal tube is provided with an air inlet connected to a compressed air source. The annular flange protruding out of the recess plays a sealing role and a role of fixing the position of the rubber tube when the buffer body is connected to the material outlet for continuously conveying materials to several filling heads and to the material inlet for the filling process of the filling head.

[0005] The two ends of the buffer body are connected to the material outlet for continuously conveying materials to several filling heads and the material inlet for the filling head filling process through nuts. The inner hole of the nut is provided with an inner flange for clamping one end of the nut on the inner side of the flange.

[0006] The nut is screwed on the material outlet of the process of continuously conveying the material to several injection heads and the material inlet of the injection head during the injection process, so that the annular flanges of the protruding outer sides of the rubber cylinder ends of the two ports of the buffer body are closely attached to the material outlet port of the process of continuously conveying the material to several injection heads and the material inlet port of the injection head during the injection process, forming a sealed connection. The material enters the rubber cylinder through the material outlet of the process of continuously conveying the material to several injection heads, and then is introduced into the material inlet of the injection head during the injection process. The compressed air of constant pressure passes through the metal cylinder body. The air inlet is introduced into the metal cylinder, so that once the fluid pressure fluctuates due to momentary cutoff during the filling process, the rubber cylinder will buffer the fluid pressure fluctuation caused by the filling process through volume changes, and a buffer space is formed between the rubber cylinder and the metal cylinder, so that when the rubber cylinder accumulates material in the rubber cylinder due to momentary cutoff during the filling process, the rubber cylinder can expand by compressing the buffer space formed between the rubber cylinder and the metal cylinder to accommodate the increased material. After the filling process is reopened, the increased material contained in the rubber cylinder can be released to ensure stable filling pressure and stable quality of the filled products.

[0007] Preferably, a plurality of longitudinal ribs are evenly arranged around the outer wall of the rubber cylinder. The longitudinal ribs can effectively ensure the shape stability of the rubber cylinder. Even if the shape of the rubber cylinder changes due to pressure fluctuations of the material, it will only expand and contract along the diameter direction, and will not deform in other directions, thus avoiding the occurrence of folding deformation of the rubber cylinder and causing blockage.

[0008] Compared with the prior art, the utility model has the advantage of being able to ensure the stability of the filling pressure during the filling process of the filling head, so as to ensure the stability of the quality of the filled product. BRIEF DESCRIPTION OF THE DRAWINGS

The inlay flange 9 is inlaid into the annular groove 7 to position the rubber cylinder 4 on the axis of the metal cylinder 3. The outer diameter of the rubber cylinder 4 is smaller than the inner diameter of the metal cylinder 3, so that a buffer space c is formed between the rubber cylinder 4 and the metal cylinder 3. The body of the metal cylinder 3 is provided with an air inlet 11 connected to a compressed air source 10. The annular flange 8 protruding from the recess 6 plays a sealing role and a role of fixing the position of the rubber cylinder 4 in the connection between the buffer body a and the material outlet 1 in the process of continuously conveying the material to several filling heads and in the connection with the material inlet 2 in the filling process of the filling head.

The inner hole of the nut 12 is provided with an inner flange 13 for clamping one end of the nut 12 on the inner side of the flange 5.

[0016] The nut 12 is screwed on the material outlet 1 of the process of continuously conveying the material to the several filling heads and the material inlet 2 of the filling head filling process, so that the annular flange 8 of the protruding outer side surface provided at the end of the rubber cylinder 4 of the two ports of the buffer body a is close to the material outlet 1 port of the process of continuously conveying the material to the several filling heads and the material inlet 2 port of the filling head filling process, forming a sealed connection.
