Description

[0002] The raw material of collagen casing mainly comes from the dermis of animals, usually collagen extracted from the skin or tendon of cattle, pigs and other livestock. Collagen itself is a natural protein and the main component of animal connective tissue. Because collagen casing is artificially reconstructed, any process fluctuation (such as slurry concentration, extrusion speed, solidification time, etc.) in the production process will lead to inconsistent product quality, so a blowing detection device for collagen casing is needed.

[0003] Through research, it is found that the existing blowing device directly inflates the whole collagen casing during use, and the whole casing is immersed in water for detection. When the whole casing is detected, there will be wrinkles on the surface of the casing, and the casing will be stacked after being immersed in water. Wrinkles and stacking will affect the discharge of bubbles at the defect of the casing, making it difficult to find bubbles, thereby reducing the detection accuracy. SUMMARY

[0046] The working principle of the embodiment is as follows:

[0047] When the casing needs to be detected by using the device, the specific operation is as follows:

[0048] Preparation work:

[0049] The operator first pulls the right pull rod 22 to the right (taking the right side as an example). The pull rod 22 drives the driving frame 21 to move to the right, and the driving frame 21 extrudes the two fixed rods 9, so that the fixed rods 9 move away and slide along the auxiliary support frame 8. The fixed rods 9 drive the clamping rollers 10 to move, thereby increasing the distance between the upper and lower distributed clamping rollers 10. Then, the operator inserts one end of the casing between the upper and lower distributed clamping rollers 10, and sleeves the casing onto the gas conveying pipe 12. The operator continues to push the casing to the right, so that the casing slides along the gas conveying pipe 12, until the end of the casing enters the fixed module 3, the gas supply module 11 is opened, and the gas supply module 11 pumps gas into the annular air bag of the right fixed module 3, so that the annular air bag gradually expands and clamps the casing. Then, the gas supply module 11 is closed, at this time the right end of the casing is fixed, and then the pull rod 22 is moved in the opposite direction, the driving frame 21 drives the upper and lower distributed clamping rollers 10 to move away from each other and clamp the casing, thereby flattening the clamped part of the casing and ensuring the sealing of the clamped position.

[0050] Before the casing enters the right fixed module 3, the end of the casing needs to pass between the two conveying rollers 42. The positions of the two conveying rollers 42 are adjusted according to the outer diameter of the casing. The specific operation is as follows: rotate the limiting screw 44 to lose contact with the vertical plate of the right fixed module 3, then slide the adjusting frame 43 up and down, the adjusting frame 43 drives the two conveying rollers 42 to move synchronously, until the opposite sides of the two conveying rollers 42 are in contact with the casing, stop moving the adjusting frame 43, then reverse the limiting screw 44 to make it contact with the vertical plate of the right fixed module 3 again and extrude it, thereby limiting the adjusting frame 43.

[0051] After the right end of the casing is fixed, the operator pulls the left pull rod 22 to the left. The pull rod 22 drives the left upper and lower distributed clamping rollers 10 to move away from each other through the driving frame 21 and the fixed rod 9. Then, the other end of the casing is inserted between the upper and lower distributed clamping rollers 10, and the casing is pushed to the left until the end of the casing contacts the left fixed module 3. The left end of the casing is fixed by controlling the gas supply module 11 and the left fixed module 3. Then, the middle part of the casing is pushed to the left, so that the casing is accumulated on the left fixed module 3. Then, the left pull rod 22 is pulled in the opposite direction, so that the upper and lower distributed clamping rollers 10 clamp the casing and ensure the sealing of the clamped position. At this time, the preparation work for the casing blowing detection is completed, and the casing between the left and right distributed clamping rollers 10 is the detection area.

[0052] After the casing is fixed, the operator rotates the rotating rod 23 according to the thickness and shape characteristics of the casing. The rotating rod 23 drives the sliding block 24 to compress the first elastic member 25, so that the first elastic member 25 stores energy, thereby increasing the resistance to the movement of the driving frame 21.

[0053] Detection work:

[0054] After the preparation work is completed, a certain amount of water is injected into the processing pool 2, and then the electric push rod 5 is started, the telescopic end of the electric push rod 5 pushes the mounting frame 6 to move downward, the mounting frame 6 drives the two main support frames 7 to move downward, and all the clamping rollers 10 jointly drive the casing detection area to move downward and enter the water, until the casing detection area is completely immersed in the water, the electric push rod 5 is turned off.

[0055] After the casing detection area is completely immersed in the water, the gas supply module 11 is started, the gas supply module 11 injects gas into the casing detection area through the two gas supply pipes 12 and makes the casing swell, at this time, under the clamping action of all the clamping rollers 10, the left and right sides of the casing detection area remain sealed, so that the casing detection area starts to swell gradually, until the casing swells to a specified state, the gas pressure in the casing detection area is kept stable by the gas supply module 11, so that the detection of the casing begins, if there is a defect on the surface of the casing, the gas in the casing detection area will be discharged, that is, bubbles will be generated on the surface of the casing, and the operator can judge the quality of the casing by observing whether there are bubbles and how many bubbles there are.

[0056] After the detection in the detection area is completed, the driving module 45 is started, the driving module 45 drives the two driving shafts 41 to rotate, the driving shafts 41 drive the conveying rollers 42 thereon to rotate, so that the two conveying rollers 42 jointly drive the casing to move to the right, the casing moves to the right and drives all the clamping rollers 10 to rotate, in the process of movement of the casing, under the action of all the clamping rollers 10, the wrinkles of the casing are flattened, so that the surface of the casing is more flat, which is convenient for the discharge of gas at the defect position and improves the accuracy of detection, in this process, the casing accumulated on the left fixed module 3 gradually decreases, until the next detection area of the casing moves between the left and right clamping rollers 10, the driving module 45 is turned off, and the gas supply module 11 injects gas into the casing detection area, so that the pressure in the new casing detection area is consistent with the initial pressure, then the detection of the new casing detection area begins, and then the above process is repeated to move the casing to the right and detect different positions of the casing in turn.

[0057] After the detection of the casing is completed, the electric push rod 5 is started, the telescopic end of the electric push rod 5 drives all the parts to move upward through the mounting frame 6, that is, the casing loses contact with the water, then the gas supply module 11 is controlled to release the fixation of the casing by the two fixed modules 3, and at the same time, the left and right pull rods 22 are pushed in turn to release the clamping of the casing by all the clamping rollers 10, then the detected casing is taken down, and the above process is repeated to detect the next casing.

[0058] In the process of moving the casing, if the casing has a hard protrusion or a hard wrinkle, the casing is squeezed against the corresponding clamping roller 10 (taking the right side as an example), so that the upper and lower clamping rollers 10 are separated, at this time the clamping roller 10 squeezes the driving frame 21, so that the driving frame 21 moves to the right and further compresses the first elastic member 25, so that the sliding of the driving frame 21 is controlled by the first elastic member 25, thereby avoiding the hard squeezing force of the upper and lower clamping rollers 10 on the casing, reducing the probability of casing damage, and after the wrinkle passes through the clamping roller 10, the driving frame 21 is reset under the action of the first elastic member 25 and the corresponding clamping roller 10 is reset.

[0059] In the process of moving the casing, if the casing swings the secondary support frame 8 through the clamping roller 10, at this time the secondary support frame 8 rotates relative to the primary support frame 7, the second elastic member 31 is twisted and stored, and in the process of rotating the secondary support frame 8, when the support frame 8 contacts the blocking block 32, the blocking block 32 limits the support frame 8, so as to control the swing range of the support frame 8.

[0060] Example 2

[0061] Based on example 1, as shown in Figure 1 , Figure 2 and Figure 4 , it further comprises: a telescopic support rod 51, having two groups of symmetrical distribution, the number of each group of telescopic support rods 51 is two, and they are symmetrically distributed front and back, and are fixedly connected to the mounting frame 6, the telescopic end of the telescopic support rod 51 is fixedly connected with the corresponding primary support frame 7 (in this embodiment, the primary support frame 7 has no direct connection with the mounting frame 6); a driving rod 52 is rotatably connected to the mounting frame 6, the driving rod 52 has two threads symmetrically distributed on the left and right, the primary support frame 7 is connected with the corresponding thread on the driving rod 52, and the driving rod 52 is used to drive the two primary support frames 7 to move towards or away from each other.

[0062] The working principle of this embodiment is as follows:

[0063] When the casing is detected by blowing, according to the detection efficiency and the range required to be detected, the distance between the two primary support frames 7 is adjusted, so as to control the distance between the left and right clamping rollers 10, when the detection range needs to be increased, the driving rod 52 is rotated, the driving rod 52 drives the two primary support frames 7 to move away from each other, at the same time, the primary support frame 7 drives the telescopic end of the corresponding telescopic support rod 51 to move, so that the telescopic end of the corresponding telescopic support rod 51 is extended, the primary support frame 7 drives all the clamping rollers 10 to move through the two secondary support frames 8 and the two fixed rods 9 on it, so that the distance between the left and right clamping rollers 10 is increased, until the primary support frame 7 is adjusted to the appropriate position, stop rotating the driving rod 52.

[0064] By increasing the distance between the left and right clamping rollers 10, the area for detecting the casing is expanded, and the efficiency of casing detection is improved. Meanwhile, the sample area for detection is increased, which can better represent the average quality of the whole casing and make the detection of uniformity defects (such as overall thinness) more reliable.

[0065] If it is necessary to improve the detection accuracy and focus on detecting small defects, the driving rod 52 is rotated in the opposite direction, and the two main support frames 7 move towards each other, thereby shortening the distance between the left and right clamping rollers 10. When the main support frames 7 are adjusted to the appropriate position, the rotation of the driving rod 52 is stopped, thereby achieving the purpose of reducing the detection area of the casing and improving the detection sensitivity of small and concentrated defects.

[0066] Embodiment 3

[0067] Based on Embodiment 2, as shown in Figure 2 、 Figures 4-6 and Figure 10 , it further comprises: two support collars 61 symmetrically distributed on the left and right, respectively rotatingly connected to the lower side of the adjacent main support frame 7. During the detection process, the casing penetrates through the support collar 61, and the gas delivery pipe 12 passes through the adjacent support collar 61. The support collar 61 is fixedly connected with two extrusion plates 62 symmetrically distributed vertically. The left extrusion plate 62 is used to pre-press the casing, so that the casing is gradually flattened. The right extrusion plate 62 guides the casing to slowly reset and open. The extrusion plate 62 is fixedly connected with the corresponding fixed rod 9, and the gas delivery pipe 12 passes through the adjacent symmetrically distributed extrusion plates 62. The extrusion plate 62 and the support collar 61 jointly guide the casing to avoid forming a bending dead angle at the clamping roller 10.

[0068] The working principle of this embodiment is as follows:

[0069] During the preparation process, the two ends of the casing are inserted between the two extrusion plates 62 on the left and right sides, respectively. Then the two ends of the casing are passed through the two support collars 61, respectively. After the preparation work is completed, the detection area of the casing is placed in the detection pool 2 and the detection begins.

[0070] During the detection of the casing, taking the right support collar 61 as an example, the support collar 61 and the two extrusion plates 62 jointly support the right part of the casing, making the part of the casing between the fixed module 3 and the clamping roller 10 more gentle, reducing the probability of forming a bending dead angle at the clamping roller 10, and thereby reducing the damage to the casing.

[0071] In the process of detecting the casing, the two left extrusion plates 62 extrude the casing, so that the part of the casing on the left side of the clamping roller 10 is gradually flattened, and the two extrusion plates 62 stabilize the casing in the correct position, preliminarily arrange and flatten it, reduce slackness and wrinkles, reduce the probability of damage to the casing after being directly extruded, ensure the reliability of the seal, thereby improving the detection accuracy, and the right extrusion plate 62 limits the casing, so that the casing slowly opens.

[0072] After the distance adjustment between the two main support frames 7 is completed, when the casing is detected, due to the change in the position of the main support frame 7, the casing will swing through all the clamping rollers 10 to control the corresponding auxiliary support frame 8. In the process of deflection of the auxiliary support frame 8, the auxiliary support frame 8 drives the adjacent extrusion plate 62 to deflect through the fixed rod 9, and the extrusion plate 62 drives the adjacent support sleeve ring 61 to deflect synchronously, that is, the deflection angles of the extrusion plate 62, the support sleeve ring 61 and all the clamping rollers 10 are consistent.

[0073] Embodiment 4

[0074] On the basis of embodiment 3, as shown in Figure 2 , Figure 4 , Figure 11 and Figure 12 , further comprising: two mounting plates 71 distributed in front and back, both fixedly connected to the mounting frame 6, and the mounting plate 71 is located between the symmetrically distributed main support frames 7; two guide plates 72, each fixedly connected to the adjacent mounting plate 71, the guide plate 72 is used for positioning the material to avoid the casing from deviating during the inspection process, and the lower side of the guide plate 72 is provided with a curved surface to make it more fit the casing; and an array of extrusion rollers 73 is rotatably connected between the two mounting plates 71, the extrusion roller 73 is used for guiding the casing to facilitate the movement of the casing, the diameter of the middle extrusion roller 73 is greater than that of the remaining extrusion rollers 73, the middle extrusion roller 73 extrudes the casing to increase the air pressure in the casing detection area, and the gas at the damaged part of the casing is easily discharged.

[0075] The working principle of the embodiment is as follows:

[0076] In the process of moving the mounting frame 6 downward, the mounting frame 6 drives the two mounting plates 71 thereon to move downward, the mounting plate 71 drives the guide plate 72 thereon to move synchronously, and the two mounting plates 71 jointly drive all the extrusion rollers 73 thereon to move, until the mounting frame 6 moves to the specified position and stops moving, the guide plate 72 and all the extrusion rollers 73 stop moving.

[0077] When the casing is inflated for detection, the two front and rear guide plates 72 wrap the upper side of the casing, so that the deformation of the casing is more regular, and the inflated casing is positioned, so that the detection area of the casing is more stable in the detection pool 2.

[0078] After the casing is inflated, the middle extrusion roller 73 extrudes the casing, increasing the pressure in the casing detection area, facilitating the discharge of gas from the casing detection area through the small defects, improving the accuracy of the casing detection, and allowing the casing to move along all the extrusion rollers 73 during the movement of the casing.
