Description

Technical Field

[0001] This utility model relates to a tension regulating and stretching device for collagen casing conveying, and belongs to the field of casing conveying tension regulation technology. Background Technology

[0002] In the production of collagen sausage casings, the casings are transported using a conveyor system. Traditional casing conveyor systems typically use a fixed set of conveyor wheels for transport, which cannot adjust the stretching of the casings according to the real-time tension during transport. Therefore, the casings obtained after transport are of a fixed length, affecting the casing yield. Utility Model Content

[0003] This invention provides a collagen casing conveying tension adjustment and stretching device, which solves the problems mentioned in the background art.

[0004] This utility model relates to a tension adjustment and stretching device for conveying collagen casings, comprising frames at both ends, with a conveying shaft rotatably mounted on each frame. Multiple conveying wheels are fixed along the axial direction of the conveying shaft, and an arc-shaped conveying groove is provided on the outer side wall of the conveying shaft. Multiple sets of support and limiting components are provided between the two frames. An electric actuator is mounted on a bracket at one end, and a tensioning plate is connected to the output end of the electric actuator. Adjusting shafts are fixed at both ends of the tensioning plate, and adjusting wheels are rotatably mounted on the adjusting shafts. A tension roller is mounted on a bracket at the other end, and a tension sensor is mounted on the tension roller.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Example 1, as Figures 1 to 6 As shown, this utility model is a collagen casing conveying tension adjustment and stretching device, including two frames 4 at both ends. A conveying shaft 2 is rotatably mounted on each frame 4. Multiple conveying wheels 1 are fixed along the axial direction on the conveying shaft 2. A driven sprocket 3 is fixed on the conveying shaft 2. The driven sprocket 3 is connected to a driving sprocket through a chain. The driving sprocket is connected to a conveying motor. An arc-shaped conveying groove is provided on the outer wall of the conveying shaft 2. Multiple sets of support and limiting components are provided between the two frames 4. An electric actuator 5 is mounted on the bracket at one end. The output end of the electric actuator 5 is connected to a tensioning plate 13. Adjusting shafts 15 are fixed at both ends of the tensioning plate 13. Adjusting wheels 6 are rotatably mounted on the adjusting shafts 15. A tension roller 12 is mounted on the bracket at the other end. A tension sensor is mounted on the tension roller 12. The tension sensor is connected to a controller. The tension sensor can be an S-type high-precision pressure sensor with a range of 50N. The controller is connected to the electric actuator 5. The electric actuator 5 can be a Siemens electric actuator, model GD2161.1E.

[0022] During operation, the sausage casing enters through the front conveyor wheel 1 at one end, then spirals around multiple conveyor wheels 1 at both ends in a front-to-back direction. Finally, the output end of the casing passes between two adjusting wheels 6 and then wraps around the bottom of the tension roller 12. The conveyor wheels 1 rotate to transport the casing. Under normal operating conditions, the electric actuator 5 will operate the two adjusting wheels 6 at an angle, causing the casing to be stretched. The tension sensor detects the real-time tension value of the casing and transmits it to the controller. The controller will, according to a preset standard value, adjust the operating angle of the two adjusting wheels 6 through the electric actuator 5. When the detected tension value is low, the angle is increased; when the detected tension value is high, the angle is decreased.

[0023] In Example 2, based on Example 1, the electric actuator 5 is fixedly connected to the mounting plate 14, which is fixed on the frame 4. The adjusting wheel 6 has an arc-shaped limiting groove on its outer circumference, and the wheel will be in the limiting groove when the casing is being conveyed.

[0024] An adjusting plate 11 is fixed to the top of the tension sensor, and a locking bolt is fixed on the adjusting plate 11. An L-shaped support plate 10 is provided above the adjusting plate 11. A vertical strip hole 22 is provided on the upper part of the support plate 10, and a fastening bolt is provided in the strip hole 22. The fastening bolt is installed on the frame 4. An adjusting hole 2 along the front-to-back direction is provided at the bottom of the support plate 10, and the locking bolt is located in the adjusting hole 2. Before operation, the locking bolt and the fastening bolt can be loosened according to the position of the adjusting wheel 6, thereby adjusting the up-down and front-to-back position of the tension roller 12.

[0025] The bottom of the multiple sets of support and limiting components is provided with an installation box 8. The support and limiting components include a base plate 20 and rollers 9 arranged alternately in the front and back direction. Each roller 9 has a limiting component on the front and back of its right side.

[0026] The limiting component includes an adjusting screw 21 fixed on the base plate 20. An adjusting sleeve 18 is provided on the adjusting screw 21. Support plates 17, fitted onto the adjusting screw 21, are located at both the upper and lower ends of the adjusting sleeve 18. An adjusting nut is located on the outer side of the middle of each support plate 17. A clamping bolt is threaded to both ends of the support plate 17. A top shaft is rotatably connected to the inner end of the clamping bolt via a bearing. A limiting nylon roller 7 is located between the upper and lower top shafts. Before operation, the position of the limiting nylon roller 7 can be adjusted by loosening the adjusting nut and rotating the adjusting sleeve 18, based on the front-to-back position of the casing on the roller 9.

[0027] Each idler roller 9 has a U-shaped bracket 16 at its bottom, which is fixed to the base plate 20. Both ends of the bracket 16 are threaded with clamping bolts 2. The inner ends of the clamping bolts 2 are rotatably connected to a top shaft 23 via bearings. Both the first and second top shafts 23 have square limiting protrusions at their inner ends. The centers of both ends of the idler roller 9 and the limiting nylon roller 7 have limiting grooves that mate with the limiting protrusions. When it is necessary to replace the idler roller 9 or the limiting nylon roller 7, rotating the clamping bolts 2 or 1 will cause the top shaft 1 or 23 to move outwards, disengaging from the limiting grooves, allowing it to be removed and replaced.

[0028] The base plate 20 has mounting holes at its four corners, with height adjustment studs 19 installed in each hole. Height adjustment nuts are attached to the height adjustment studs 19 on both the top and bottom of the base plate 20, and the studs 19 are fixed to the mounting box 8. Before operation, the height of the idler roller 9 can be adjusted by rotating the height adjustment nuts to the top or bottom positions of the height adjustment studs 19.
