Description

Technical Field

[0001] This utility model relates to the field of fish intestine filling, and in particular to an intelligent precision-controlled automatic fish intestine filling machine. Background Technology

[0002] Casings are the outer packaging of fish sausage products. Their basic function is to ensure that the fish sausage products do not spoil under certain conditions and within a certain time frame, thus meeting the needs of storage and distribution. This function is provided by the barrier properties of the casings, namely oxygen barrier, moisture barrier, and aroma barrier. Under the protection of the casings, bacteria from the outside of the fish sausage products cannot enter the interior.

[0003] Currently, industrialized fish sausage filling mostly uses semi-automatic equipment, whose core processes rely on manual operation: for example, the casing needs to be manually attached to and secured to the filling tube, the filling volume is controlled by mechanical valves, and the casing is manually cut off or stopped by simple sensors after filling. This type of equipment suffers from insufficient automation (e.g., casing fixation relies on manual intervention) and poor accuracy and stability (relying on manual calibration, with weight errors often reaching ±3%-5%), making it difficult to meet the rigid demands of modern food processing for high precision, high hygiene standards, and continuous production. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art by designing an intelligent precision-controlled automatic fish intestine filling machine.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: an intelligent precision-controlled automatic fish intestine filling machine, comprising a feeding device, a device base, and a conveying pipe. The feeding device is fixedly installed above the device base, and the conveying pipe is fixedly installed at the outlet on the right side of the feeding device. A servo motor is fixedly installed above the outer side of the conveying pipe, and a transmission gear is fixedly installed at the output end of the servo motor. An end face gear is rotatably installed on a limiting cylinder near the feeding device. The limiting cylinder is fixedly installed on the conveying pipe and is aligned with the axis of the conveying pipe. A rotating cylinder is fixedly installed on the side of the end face gear away from the feeding device and is aligned with the axis of the conveying pipe. Several arc-shaped blocks are equidistantly distributed inside the rotating cylinder and fixedly connected to the rotating cylinder. Each arc-shaped block is slidably connected to one end of a clamping block near the conveying pipe. The clamping block is slidably installed on the limiting cylinder. A pressure sensing device is fixedly installed on the device base and its position corresponds to the outlet position of the conveying pipe.

[0006] Preferably, the feeding device includes a spiral feeding pipe, a device housing, a hopper, and a power motor. The spiral feeding pipe is rotatably installed inside the device housing, the hopper is fixedly installed at the inlet of the device housing, the feeding pipe is fixedly installed at the outlet of the device housing, and the power motor is fixedly installed outside the device housing. The output end of the power motor is fixedly connected to the spiral feeding pipe.

[0007] Preferably, the pressure sensing device includes a load cell, a protective housing, a support frame, and rollers. The load cell is fixedly installed inside the protective housing. One end of the support frame is located on the load cell and fixedly installed on the sensing side of the load cell. The other end of the support frame extends out of the protective housing and is rotatably connected to the left and right ends of the rollers. The support frame is slidably installed on the protective housing.

[0008] Preferably, the clamping block is provided with a silicone pad, which is fixedly installed on the end of the clamping block near the feed pipe.

[0009] Preferably, the feeding device is electrically connected to the pressure sensing device, the servo motor is electrically connected to the feeding device, and the servo motor is electrically connected to the pressure sensing device.

[0010] Beneficial effects: This utility model provides an intelligent precision-controlled automatic fish intestine filling machine, which has the following beneficial effects. Through its structural design, when filling fish intestines, the device only requires placing the casing on the pressure sensing device and fitting the end into the opening of the conveying pipe. Then, pressing the start switch activates the servo motor, which drives the transmission gear to rotate. The transmission gear rotates the end face gear on the limiting cylinder, which in turn rotates the rotating cylinder. The rotating cylinder's rotation causes the arc-shaped block to move around its axis. This movement of the arc-shaped block causes the clamping block to slide inwards along the direction of the limiting cylinder, thus fixing the end of the casing to the opening of the conveying pipe. Since the distance the clamping block moves is fixed each time, the servo motor... The servo motor operates at a fixed angle at its output end. When the servo motor rotates to the maximum range of the specified angle, it means that the end of the casing has been fixed. At this time, the servo motor stops running and the feeding device starts. The feeding device transports fish paste and other materials along the conveying pipe into the casing, completing the filling of the fish intestines. During the filling process, the fish intestines located on the pressure sensing device gradually increase in weight as the material is filled. When the pressure sensing device senses that the weight of the fish intestines has increased to the specified weight, it automatically shuts off the feeding device and starts the servo motor to reverse. The reverse rotation of the servo motor causes the clamping block to no longer clamp the end of the casing. At this time, the worker can remove the filled fish intestines from the opening of the conveying pipe, completing the filling process of the fish intestines. Compared to existing technologies, this invention utilizes a servo motor-driven gear set linkage clamping mechanism to achieve fully automatic and precise fixing and release of the sausage casing end. Combined with a pressure-sensing real-time feedback system, it dynamically monitors the weight of the fish sausage during the filling process, immediately stopping feeding and releasing the clamp when the preset value is reached. This ensures that the weight error of each fish sausage approaches zero (e.g., within ±1%), significantly improving product consistency. Its closed-loop automated process (fixing → filling → detection → releasing) not only improves efficiency (supporting continuous operation) but also avoids human error and contamination risks through standardized operations, providing the fish sausage processing industry with a high-precision, high-hygiene standard intelligent solution.

[0016] Please see Figure 1-7This utility model provides a technical solution: an intelligent precision-controlled automatic fish intestine filling machine, including a feeding device 1, a device base 2, and a conveying pipe 3. The feeding device 1 is fixedly installed above the device base 2, and the conveying pipe 3 is fixedly installed at the outlet on the right side of the feeding device 1. A servo motor 4 is fixedly installed above the outside of the conveying pipe 3. A transmission gear 5 is fixedly installed at the output end of the servo motor 4. An end face gear 6 is rotatably installed on a limiting cylinder 7 near one end of the feeding device 1. The limiting cylinder 7 is fixedly installed on the conveying pipe 3 and is aligned with the axis of the conveying pipe 3. A rotating cylinder 8 is fixedly installed on the side of the end face gear 6 away from the feeding device 1 and is aligned with the axis of the conveying pipe 3. Several arc-shaped blocks 9 are equidistantly distributed inside the rotating cylinder 8 and are fixedly connected to the rotating cylinder 8. Each arc-shaped block 9 is slidably connected to one end of a clamping block 10 on the side near the conveying pipe 3. The clamping block 10 is slidably installed on the limiting cylinder 7. A pressure sensing device 11 is fixedly installed on the device base 2 and its position corresponds to the outlet position of the conveying pipe 3.

[0017] In this utility model, the feeding device 1 includes a spiral feeding pipe 101, a device housing 102, a hopper 103, and a power motor 104. The spiral feeding pipe 101 is rotatably installed inside the device housing 102. The hopper 103 is fixedly installed at the inlet of the device housing 102. The conveying pipe 3 is fixedly installed at the outlet of the device housing 102. The power motor 104 is fixedly installed outside the device housing 102. The output end of the power motor 104 is fixedly connected to the spiral feeding pipe 101. When the power motor 104 starts, it drives the spiral feeding pipe 101 to rotate inside the device housing 102. The rotation of the spiral feeding pipe 101 drives materials such as fish paste to be conveyed from the hopper 103 to the conveying pipe 3 at the outlet.

[0018] In this invention, the pressure sensing device 11 includes a load cell 111, a protective housing 112, a support frame 113, and rollers 114. The load cell 111 is fixedly installed inside the protective housing 112. One end of the support frame 113 is located on the load cell 111 and fixedly installed on the sensing side of the load cell 111. The other end of the support frame 113 extends out of the protective housing 112 and is rotatably connected to the left and right ends of the rollers 114. The support frame 113 is slidably installed on the protective housing 112. During the filling process, the pressure sensing device 111 is located on the load cell 111. As the material is filled, the fish intestines on the feeding device 11 gradually increase in weight. The increasing weight of the fish intestines transmits the pressure generated by the weight to the roller 114, and then from the roller 114 to the support frame 113. The rolling characteristics of the roller 114 allow the fish intestines to naturally stretch or slightly shift during the filling process, thereby improving the accuracy of weight detection. When the weighing sensor 111 inside the protective housing 112 senses that the weight of the fish intestines above the roller 114 has increased to the specified weight, it automatically shuts off the feeding device 1 and starts the servo motor 4 to reverse.

[0019] In this utility model, a silicone pad 12 is provided on the clamping block 10. The silicone pad 12 is fixedly installed on the end of the clamping block 10 near the feed pipe 3. The silicone pad 12 on the clamping block 10 increases the contact resistance between the clamping block 10 and the end of the casing, preventing the casing from slipping off due to pressure or vibration during the filling process; at the same time, it buffers the mechanical clamping force to avoid rigid clamping causing indentations or damage to the casing.

[0020] In this invention, the feeding device 1 is electrically connected to the pressure sensing device 11, the servo motor 4 is electrically connected to the feeding device 1, and the servo motor 4 is electrically connected to the pressure sensing device 11. The electrical connection between the feeding device 1, the pressure sensing device 11 and the servo motor 4 makes the whole process more automated.

[0021] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0022] In this implementation scheme: when filling fish intestines, simply place the casing on the pressure sensing device 11 and fit the end into the opening of the conveying pipe 3. Then, press the start switch. The servo motor 4 runs, driving the transmission gear 5 to rotate. The rotation of the transmission gear 5 drives the end face gear 6 to rotate on the limiting cylinder 7. The rotation of the end face gear 6 drives the rotating cylinder 8 to rotate together. The rotation of the rotating cylinder 8 drives the arc-shaped block 9 to move around the axis of the rotating cylinder 8. The movement of the arc-shaped block 9 drives the clamping block 10 to slide inward along the direction of the limiting cylinder 7, thereby clamping the end of the casing. The clamping block 10 is fixed at the opening of the conveying pipe 3. The silicone pad 12 on the clamping block 10 increases the contact resistance between the clamping block 10 and the end of the casing, preventing the casing from slipping due to pressure or vibration during filling. Simultaneously, it buffers the mechanical clamping force, avoiding indentations or damage to the casing caused by rigid clamping. Since the distance the clamping block 10 moves each time is fixed, the rotation angle of the output end of the servo motor 4 is also fixed each time it runs. Therefore, when the servo motor 4 rotates to the maximum range of the specified angle, it indicates that the end of the casing has been fixed, and at this point, the servo motor 4 stops operating. When the feeder 1 is activated, the motor 104 starts and drives the spiral feeder 101 to rotate inside the casing 102. The spiral feeder 101 rotates and transports fish paste and other materials from the hopper 103 to the feed pipe 3 at the outlet. The feeder 1 then transports the fish paste and other materials along the feed pipe 3 into the casing, completing the filling of the fish intestines. During the filling process, the fish intestines located on the pressure sensing device 11 gradually increase in weight as the material is filled. The gradually increasing weight of the fish intestines transmits the pressure generated by the weight to the roller 114, which then transmits the pressure. The rolling characteristics of the roller 114, which is handed to the support frame 113, allow the fish intestines to naturally stretch or slightly shift during the filling process, thereby improving the accuracy of weight detection. When the weighing sensor 111 inside the protective shell 112 senses that the weight of the fish intestines above the roller 114 has increased to the specified weight, the feeding device 1 is automatically shut off and the servo motor 4 is started to reverse. The reverse rotation of the servo motor 4 causes the clamping block 10 to no longer clamp the end of the casing. At this time, the worker can remove the filled fish intestines from the opening of the conveying pipe 3, thus completing the filling process of the fish intestines.
