Technical Field

[0001] The utility model relates to the technical field of casing shrinkage, in particular to a pressing wheel device used before casing shrinkage. Background Art

[0002] Currently, the casings that can be directly eaten in the food industry include collagen casings and natural casings. Collagen casings are easy to use, rich in protein nutrition, good taste, easy to eat, beige tubular and smooth in shape, and can be used for boiling, frying, smoking, baking, etc. Its compressive strength is 3-5 times that of natural casings. In a constant temperature and humidity environment, it can extend the shelf life of the product and keep the original quality unchanged, which has a strong advantage over other casings.

[0003] In the casing production process, casing shrinking machines are required for shrinking, cutting and transporting to produce shrink casing tubes of different specifications. Before the casing is shrunk, it is released from the casing roller and inflated during transportation. During this process, a pair of pressing wheels are usually used to compact the inflated casing during transportation to prevent the airflow in the casing from retreating and causing casing breakage and equipment shutdown. However, in actual applications, the sealing effect of existing casing pressing wheels is not ideal. There is still a phenomenon of excessive airflow retreating and even reaching the casing roller, causing casing breakage and shutdown, which seriously affects the production and quality of the casing. At the same time, it also increases the frequency and workload of employees operating the equipment, resulting in low production efficiency and increased enterprise costs. Utility Model Content

[0029] Embodiment 1

[0030] In a typical embodiment of the present application, a pressing wheel device is provided for casing shrinkage. The pressing wheel device is installed between a casing release roller and a casing shrinkage machine on a casing shrinkage production line to press the casings in transportation after inflation up and down to prevent the compressed air in the casings from returning to the casings before inflation at the rear end or even to the casing release roller, causing casing breakage and equipment shutdown.

[0031] like Figure 1-4 As shown, the pressing wheel device includes a frame 1 and a pressing wheel assembly installed on the frame, the pressing wheel assembly includes an upper pressing wheel 2, a lower pressing wheel 3 and an auxiliary pressing wheel 4, the upper pressing wheel 2 and the lower pressing wheel 3 are arranged in parallel and the outer circumferential surfaces are in contact with each other, the lower pressing wheel is a stainless steel wheel, and the outer surface of the lower pressing wheel 3 is provided with a V-shaped groove; the auxiliary pressing wheel 4 is arranged on the side surfaces of the upper and lower pressing wheels, and the bottom end of the auxiliary pressing wheel 4 is lower than the bottom end of the upper pressing wheel 2; the lower pressing wheel is driven by an electric motor and fits tightly with the upper pressing wheel. At the same time, during the smooth conveying of the casing, the auxiliary pressing wheel 4 fits tightly with the lower pressing wheel 3, which effectively prevents the casing from breaking and equipment shutdown failure.

[0032] Specifically, Figure 1 As shown, the frame 1 is placed on the ground, and a cylinder 6 is installed at the upper end of the frame for providing power. The telescopic rod at the lower end of the cylinder is connected to a universal floating joint 7 for connecting the cylinder and the frame part. The angle and position can be flexibly adjusted according to the actual situation, the eccentricity difference between the cylinder and the components can be buffered and guided, the cylinder movement can be optimized, and it can adapt to different working environments, enhance the cylinder connection, withstand the pressure of the cylinder bracket and improve the reliability of the auxiliary pressure wheel. The universal floating joint can adopt the FD-M18*1.5 model product on the market. In this embodiment, the upper pressure wheel 2 and the auxiliary pressure wheel 4 are both fixedly arranged on the pressure wheel bracket 8, and the top of the pressure wheel bracket 8 is fixedly connected to the universal floating joint 7. When the cylinder 6 is extended and retracted, the pressure wheel bracket 8 is driven to move up and down through the universal floating joint 7, and the gap between the upper pressure wheel and the lower pressure wheel can be adjusted, so as to adjust the compression state of the casing when passing between the upper and lower pressure wheels, and at the same time ensure that the casing is not punctured, and the inflation pressure in the casing is not too high or too low.

[0033] In order to improve the effect of blocking airflow and achieve efficient casing shrinkage, such as Figure 2 As shown, in this embodiment, two auxiliary pressing wheels are provided, and the two auxiliary pressing wheels 4 are both mounted on the pressing wheel bracket and are respectively located on both sides of the upper pressing wheel. The bottom end of the auxiliary pressing wheel is lower than the bottom end of the upper pressing wheel. During the smooth conveying of the casing, the auxiliary pressing wheel and the V-shaped lower pressing wheel are in close contact, so that the casing is in a downward curved arc when passing through the pressing wheel assembly, rather than passing straight. Therefore, the airflow can be better blocked by the height change on the basis of the compression of the upper and lower pressing wheels. When the upper pressing wheel rotates with the rotation of the lower pressing wheel and the friction with the casing, the lower pressing wheel drives the auxiliary pressing wheels on both sides to rotate, ensuring the smooth conveying of the casing.

[0034] Among them, the upper pressing wheel and the auxiliary pressing wheel are both wrapped with polyurethane, which has good wear resistance and shock absorption, strong load-bearing capacity, long service life and low maintenance cost.

[0035] The lower pressing wheel is a stainless steel grooved wheel. The V-groove design allows the inflated casing to be better pressed between the upper pressing wheel and the lower pressing wheel while ensuring the casing quality. The auxiliary pressing wheel and the lower pressing wheel are in close contact, effectively blocking the airflow from retreating. Figure 5 As shown, the groove width d of the V-groove is 2-2.5 mm, the groove depth h is 1.5-2 mm, and the opening of the V-groove is processed with a 0.3 mm chamfer. This shape can effectively block the airflow retreat while preventing the V-groove on the surface of the lower pressing wheel from piercing the casing.

[0036] Among them, Figure 2 , 3 As shown, the axis of the upper pressing wheel 2 and the axis of the lower pressing wheel 3 are located in the same vertical direction to ensure that the upper pressing wheel and the lower pressing wheel are in close contact and block the passage of compressed air in the casing.

[0037] In this embodiment, a solenoid valve switch 9 is also provided on the top of the frame 1. The solenoid valve switch 9 is connected to the cylinder 6. The airflow device is controlled by electromagnetic force, which can control the interruption of airflow or change the flow direction of compressed air. Specifically, the solenoid valve changes the flow direction of compressed air by controlling the power supply and power loss of the control coil, thereby controlling the switch of the pneumatic valve, quickly cutting off the gas flow, and accurately adjusting the opening and closing degree of the two upper pressure wheels and the lower pressure wheel.

[0038] like Figure 1 , 3As shown, a motor 5 is installed on one side of the frame 1, and the pressure wheel shaft of the lower pressure wheel 3 is coaxially connected with the motor output shaft. The motor 5 drives the lower pressure wheel to rotate, thereby driving the pressure wheel assembly to act on the passing casing to block the compressed air flow. A metering device 10 is installed on the other side of the frame. The metering device 10 is connected to the lower pressure wheel 3 and acts on the lower pressure wheel to convert mechanical motion into electrical signals for processing and storage in the digital system, thereby improving the accuracy and sensitivity of the system. In this embodiment, the metering device adopts the existing E6B2-CWZ6C model metering device product, which provides accurate position and motion information by detecting and recording the changes in the position, speed and direction of the casing. When used in combination with the drive system, precise position control and positioning can be achieved, thereby improving production efficiency and quality.

[0039] like Figure 4 As shown, in this embodiment, the upper pressing wheel and the auxiliary pressing wheel are connected to the pressing wheel bracket by bolts, which is convenient for disassembly.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Those skilled in the art should understand that the utility model can be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
