Problems solved by technology
Since the gas pressure for maintaining the molding is only tens of Pascals, it is relatively small and needs to be finely adjusted to produce casings with a more suitable outlet diameter. Attention, it is easy to get tired, which brings troubles to the production of high-quality casings

Embodiment Construction
[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0041] When the present invention is in use, the end close to the ground is defined as the lower end or the bottom end, and the other end away from the ground is defined as the upper end or the top end accordingly.
[0042] The main idea of the present invention is: complete the adjustment of the return air pressure of the casing through the following steps:
[0043] (1) Setting: According to the inner diameter of the casing to be produced, set the return air pressure standard value and the deviation range corresponding to the return air pressure standard value;
[0044] (2) Detection: detection of the return air pressure of the casing;
[0045] (3) Control: Calculate the difference between the return air pressure detected in step (2) and the return air pressure standard value set in step (1), and determine whether the difference i...

The invention discloses a method and device for regulating the pressure of casing returning air, which belongs to the technical field of casing, and includes an air pressure regulating valve, and is characterized in that it also includes a power actuator, a controller and a pressure sensor. The power actuator has a rotating shaft connected to a There is a shaft sleeve, which can move along the axial direction of the rotating shaft. The shaft sleeve is connected to the electromagnetic clutch, and the armature of the electromagnetic clutch is fixed on the valve stem of the air pressure regulating valve; a pressure sensor is installed in the air outlet of the air pressure regulating valve. The sensor provides a pressure detection signal for the controller, and the controller controls and connects the power actuator. The device can make the controller control the rotating shaft of the power actuator, drive the valve stem to rotate to adjust the ventilation flow of the air pressure regulating valve, and switch the connection and disconnection state between the rotating shaft and the valve stem through the electromagnetic suction device, so as to realize the automatic control of the valve stem , thus avoiding the high skill requirements of the prior art.
Description
technical field [0001] The invention belongs to the technical field of casings, and in particular relates to a method and a device for regulating pressure by returning air to casings. Background technique [0002] Casings are used to fill sausages and enemas. They are mainly divided into natural casings, collagen casings and polyvinylidene chloride (PVDC) casings. Since natural casings have the disadvantages of relying entirely on manual operations and irregular thickness, collagen casings can make up for the above shortcomings and are gradually being widely used. [0003] The current collagen casings are generally formed by air blowing. After the collagen is blown into a tube, the tube wall has a certain degree of air permeability, resulting in leakage of the blowing gas. Therefore, it is necessary to add a certain pressure of gas to form a specific specification. casings. It can be seen that the size of the air supply pressure directly affects the inner diameter of the c...
