[0007] In this solution, the sealing member includes a silicone sealing gasket, which is elastically sleeved on the outer wall of the sleeve joint. The silicone sealing gasket can not only improve the sealing performance, but also increase the friction between the fastening wrapping sleeve and the sleeve joint, thereby better locking the casing and preventing it from falling off.

[0008] In this solution, the sealing fastener includes a fastening internal threaded sleeve that is detachably locked together with the outer wall of the peripheral side of the repair sleeve and a fastening wrapping sleeve that is integrally connected to the fastening internal threaded sleeve near one end of the casing, and the inner circle diameter of the fastening internal threaded sleeve is smaller than the inner circle diameter of the fastening wrapping sleeve. The outer wall of one end of the peripheral side of the repair sleeve and near the sleeve positioning portion is provided with an external threaded path, and the inner wall of the fastening internal threaded sleeve is provided with an internal thread that is threadedly connected to the external threaded path, so that when the fastening wrapping sleeve needs to be moved to wrap the silicone sealing gasket, the fastening internal threaded sleeve is threadedly connected to the external threaded path and screwed in, so as to be detachably locked together with the repair sleeve.

This design can not only ensure that the hole patch fits the casing piece tightly, but also prevent the patch from falling off, thereby improving the stability and firmness of the repair.

[0016] The repair annular inner support airbag bag and the repair annular outer support airbag bag can be flexibly moved and adjusted according to the specific location of the hole, which is suitable for repairing holes in different locations and improves the repair efficiency.

[0017] By repairing the inner and outer clamping supports of the annular inner support airbag and the annular outer support airbag, not only a stable supporting force is provided during the repair process, but also a "sandwich structure" is formed after the repair is completed. This structure enables the hole patch to withstand greater mechanical stress in subsequent use and reduces the risk of secondary damage caused by external pressure or stretching.

[0018] The repaired casing may be squeezed or stretched in actual use, especially during the filling and transportation of sausages, ham and other meat products. The design of internal and external clamping supports makes the adhesion between the patch and the casing more solid, reduces the possibility of the patch falling off, and thus improves the long-term durability of the repaired part.

[0030] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0031] Unless otherwise defined, the up, down, left, right, front, back, inside and outside directions involved in this document are based on the up, down, left, right, front, back, inside and outside directions in the figures shown in the present invention, and are explained here together.

[0032] This embodiment provides Figures 1 to 8The casing repair component shown in the figure comprises a U-shaped bracket 1, one end of which is provided with a repair sleeve 2, one end of which is sleeved with a casing 3, and the casing 3 is fastened together at the sleeved end by a sealing fastener 6, the end of the casing 3 away from the repair sleeve 2 is tied and sealed by a tying rope, the end of the repair sleeve 2 away from the casing 3 is sealed by an air compressor gun, and the wind enters the casing 3 along the cavity of the repair sleeve 2, so that the casing 3 is inflated and expanded, and the cavity of the repair sleeve 2 has a hole that can extend to the inner cavity of the casing 3 and is sealed by an air compressor. A repair annular inner supporting airbag 29 is inflated by a machine gun to apply force to the hole in the casing piece 3, and a gap on the outer wall of the circumferential side of the repair sleeve piece 2 is provided with a repair annular outer supporting airbag 5 that can be moved to the hole on the circumferential side of the casing piece 3 to align with the repair annular inner supporting airbag 29 and is inflated by an external air pump to apply force to wrap and support a patch of the hole in the casing piece 3 (a small piece of casing made of the same material as the original casing is selected as the patch material), and a flip transmission mechanism 8 for flipping the casing piece 3 to the repairing position is arranged on the outside of the end of the repair sleeve piece 2 away from the casing piece 3. When the repair annular inner support airbag bag 29 and the repair annular outer support airbag bag 5 are used together, the hole patch is pasted on the hole by edible glue, the repair annular inner support airbag bag 29 is expanded and supported inside the casing piece 3, and the repair annular outer support airbag bag 5 is expanded and wrapped to support the hole patch outside the casing piece 3, so that the inside and outside clamps support the hole and the hole patch of the casing piece 3, thereby not only repairing the hole, but also preventing the hole patch from falling off, and further improving the bonding stability of the hole patch under the internal and external support forces, and at the same time, the contact part of the hole patch can be better embedded in the casing piece 3 under the action of internal and external forces, improving the stability while also being able to integrate with the original casing piece 3, and the design of the flipping transmission mechanism 8 can drive the casing piece 3 to flip, so that the hole to be repaired faces upward and the hole patch faces upward, preventing the hole patch from falling off when it is unstable after gluing.

[0033] In this embodiment, a sleeve positioning portion 13 is arranged on the peripheral side of one end of the repair sleeve 2 close to the casing portion 3, and a sleeve joint portion 14 of the casing portion 3 is elastically expanded and elastically sleeved on the sleeve positioning portion 13, and a sealing fastener 6 is fastened and wrapped around the outside of the sleeve joint portion 14 through a sealing member.

[0034] In this embodiment, the sealing member includes a silicone sealing gasket 15, which is elastically sleeved on the outer wall of the sleeve joint portion 14. The silicone sealing gasket 15 can not only improve the sealing performance, but also increase the friction between the fastening wrapping sleeve 17 and the sleeve joint portion 14, thereby better locking the casing 3 and preventing it from falling off.

[0035] In this embodiment, the sealing fastener 6 includes a fastening internal threaded sleeve 18 that is detachably locked together with the outer wall of the peripheral side of the repair sleeve 2 and a fastening wrapping sleeve 17 that is integrally connected to the fastening internal threaded sleeve 18 near one end of the casing 3, and the inner circle diameter of the fastening internal threaded sleeve 18 is smaller than the inner circle diameter of the fastening wrapping sleeve 17. An external threaded tooth path 16 is provided on the outer wall of one end of the peripheral side of the repair sleeve 2 and near the sleeve positioning portion 13, and an internal thread that is threadedly connected to the external threaded tooth path 16 is provided on the inner wall of the fastening internal threaded sleeve 18, so that when the fastening wrapping sleeve 17 needs to be moved to wrap the silicone sealing gasket 15, the fastening internal threaded sleeve 18 is threadedly connected to the external threaded tooth path 16 and screwed in, so as to be detachably locked with the repair sleeve 2.

[0036] In this embodiment, the inner ring of the tightening and wrapping sleeve 17 is interference-fitted with the outer wall of the circumferential side of the silicone sealing gasket 15, so that the tightening and wrapping sleeve 17 tightens and wraps the silicone sealing gasket 15, the sleeve joint part 14 and the sleeve positioning part 13 in sequence, thereby improving the sealing performance of the casing part 3 and the repair sleeve part 2.

[0037] In this embodiment, the outer wall of the repair annular inner support airbag 29 is symmetrically provided with two circles of expanded wrinkle friction parts 32. When the repair annular inner support airbag 29 is inflated, the two circles of expanded wrinkle friction parts 32 move away from each other along the arrow directions of a and b, so that the wrinkles around the hole are expanded in the inner cavity of the casing 3, thereby exposing the hole. After the wrinkles around the hole are expanded and the hole is exposed, the repair annular outer support airbag 5 is moved to the position aligned with the repair annular inner support airbag 29. The order is that the repair annular inner support airbag 29 expands the wrinkles first to prevent it from being tightly wrapped by the repair annular outer support airbag 5 when the wrinkles are not expanded. This will easily cause wrinkle gaps, thereby improving the fit of the hole patch to the outer wall of the hole, preventing the wrinkles from causing wrinkle gaps between the hole patch and the outer wall of the hole, and reducing the bonding stability.

[0038] In the present embodiment, the outer wall of each circle of the pleat-opening friction portion 32 is provided with anti-skid patterns, which increase the friction with the inner wall of the casing piece 3 and help to open the pleats. In some embodiments, the outer wall of each circle of the pleat-opening friction portion 32 may also be provided with anti-skid bumps (not shown in the figure), which can also increase the friction with the inner wall of the casing piece 3 and help to open the pleats.

[0039] In this embodiment, the outer wall of the repair annular outer support airbag bag 5 is provided with a second air inlet pipe 19, and the second air inlet pipe 19 inputs hot air into the inner cavity of the repair annular outer support airbag bag 5 through an external air pump and a hot air blower. After the repair annular outer support airbag bag 5 expands, the outer support inner ring 20 is tightly wrapped around the casing 3 and the hole patch, providing uniform external pressure, ensuring that the hole patch is tightly fitted to the casing 3, and enhancing the stability and firmness of the repair. The hot air input by the hot air blower makes the repair annular outer support airbag bag 5 a repair annular outer support airbag bag 5 with heat. When the outer support inner ring 20 wraps the casing 3 and the hole patch, the edible adhesive of the hole patch quickly adheres to the hole patch under the clamping of internal and external forces and the drying of heat, thereby accelerating the repair of the hole, and further improving the stability of the hole patch and the quality of the hole repair. The hot air output by the hot air blower can not only expand the repair annular outer support airbag bag 5 to wrap the hole patch, but also transfer heat to the hole patch. The repair annular outer support airbag bag 5 provides support for the outside of the casing 3 to ensure that the hole patch can fit tightly. After the hot air is input through the second air inlet pipe 19 to expand, the outer support inner ring 20 tightly wraps the casing 3 and the hole patch. The hot air input by the hot air blower not only expands the repair annular outer support airbag bag 5, but also transfers heat to the hole patch to accelerate the curing of the edible viscose. Under the clamping of internal and external forces and heat drying, the bonding of the hole patch is accelerated to improve the repair quality. Through the transfer of hot air, the bonding strength of the hole patch is enhanced to ensure that the repaired casing 3 has good durability. The hot air blower inputs hot air to the repair annular outer support airbag bag 5 through the second air inlet pipe 19, which not only accelerates the drying and bonding process of the edible viscose, but also has a positive effect on the material of the casing 3. The effect of the hot air makes the casing 3 slightly softened during the repair process, increases its flexibility, and reduces the discomfort caused by the hardening of the casing 3 after the repair. This improvement in flexibility allows the repaired casing piece 3 to better adapt to different shapes and bends during subsequent processing and use, reduces the risk of rupture or breakage due to hardening of the material, and further increases the service life of the repaired casing piece 3.

[0040] In this embodiment, a cross fixing rod 33 is fixed to the inner wall of the end of the repair sleeve 2 away from the casing 3, and an electric push-pull rod 30 is fixed to the center of the inner wall of the cross fixing rod 33. The electric push-pull rod 30 is coaxially arranged with the repair sleeve 2, and a bearing support rod 28 is fixed to the telescopic free end of the electric push-pull rod 30 away from the cross fixing rod 33. The repair annular inner support airbag bag 29 is fixedly sleeved on the outer wall of the free end of the bearing support rod 28 to ensure that the repair annular inner support airbag bag 29 can accurately extend to the hole inside the casing 3 to provide effective internal support. The end of the repair sleeve 2 away from the casing 3 is threadedly connected to a detachable sealing tail cover 27, and the detachable sealing tail cover 27 is sealed and connected with the first air inlet pipe 11, which provides good sealing performance to prevent gas leakage, and is easy to disassemble and inspect internal components for maintenance. The starting end of the first air intake pipe 11 is connected to the air compressor gun, and the first air intake pipe 11 extends to the end in the repair sleeve 2 and is integrally formed with two branch air pipes 34, one of which is integrally connected with a gas hose 31, and the end of the gas hose 31 away from the branch air pipe 34 is sealed and connected with the repair annular inner support air bag 29, and the other branch air pipe 34 is placed in the inner cavity of the repair sleeve 2 for inflating the casing 3. There are solenoid valves 35 in the two branch air pipes 34, and each solenoid valve 35 is installed with a radio frequency receiver (not shown in the figure). There is a radio frequency transmitter remote control in the workshop or in the hands of the operator. By operating the buttons on the radio frequency transmitter remote control, a signal can be sent to the receiver, thereby controlling the opening and closing action of the solenoid valve 35, so as to select the required pipeline direction of the input air; ensure that the gas can smoothly enter the part that needs to be inflated to support the repair process, and through the control of the solenoid valve 35, gas can be selectively supplied to different parts, thereby improving the flexibility and accuracy of the operation.

[0041] In this embodiment, there is a junction box (not shown in the figure) on the back side of the cross fixing rod 33, and the junction box has a battery (not shown in the figure) for powering the electric push-pull rod 30. The battery is removed when charging is needed, and is always in the junction box when charging is not needed or there is power. At the same time, the junction box also has a switch (not shown in the figure) for controlling the opening and closing of the electric push-pull rod 30. A radio frequency receiver (not shown in the figure) is arranged on the switch. There is a radio frequency transmitting remote control in the workshop or in the hands of the operator. By operating the button on the radio frequency transmitting remote control, a signal can be sent to the receiver, thereby controlling the telescopic switch action of the electric push-pull rod 30.

[0042] In this embodiment, a sealed bearing 24 is embedded in the upper part of one end of the U-shaped bracket 1, and the outer wall of the repair sleeve member 2 is interference fit with the inner ring of the sealed bearing 24, so as to facilitate the flipping action of the casing member 3. The bundling end 4 of the casing member 3 is bundled by a bundling rope, and a bundling integrated bundle portion 12 is reserved after bundling. A limit locking component 7 is provided on one side of the U-shaped bracket 1. The limit locking component 7 includes an integrated bundle accommodating hole 25 opened at the upper part of the other end of the U-shaped bracket 1 and a locking bolt 26 threadedly penetrated and connected to the top surface of the U-shaped bracket 1 above the integrated bundle accommodating hole 25. The locking bolt 26 penetrates into the integrated bundle accommodating hole 25 to squeeze and limit the bundling integrated bundle portion 12 in the integrated bundle accommodating hole 25, so that the casing member 3 is in a horizontal state, so as to facilitate the extension and movement of the repair annular inner support airbag bag 29. A waste receiving groove 9 is provided directly below the casing member 3 and located on the inner bottom wall of the U-shaped bracket 1.

[0043] In this embodiment, a support plate 10 is provided at one end of the U-shaped bracket 1 close to the repair sleeve 2, and the flip transmission mechanism 8 includes a servo motor 23 fixed to the upper inner wall of the support plate 10, a driving gear 22 fixed to the output shaft of the servo motor 23, and a driven gear 21 with an interference fit on the outer wall of the peripheral side of the repair sleeve 2, and the driving gear 22 is meshed and connected with the driven gear 21. The servo motor 23 drives the driving gear 22 to rotate, so that the driving gear 22 drives the driven gear 21 to mesh and rotate, thereby driving the repair sleeve 2 and the casing 3 to rotate, so as to adjust the position and direction of the hole, so as to make it easier to face the hole upward, facilitate the repair operation, and prevent the hole patch from falling off. Through rotation control, it is ensured that the hole position is always at the best repair angle, thereby improving the repair efficiency and quality. When the casing piece 3 rotates, the repair annular inner support airbag 29 and the repair annular outer support airbag 5 are not in an expanded state. At the same time, when the casing piece 3 rotates, the bundle end 4 and the bundle integrated bundle 12 will not interfere with each other. The bundle end 4 and the bundle integrated bundle 12 are themselves part of the casing. When the casing piece 3 rotates, the bundle integrated bundle 12 is fixed in position, so that the bundle end 4 is twisted, which is more conducive to sealing. At the same time, the repair sleeve 2 and the casing piece 3 will not exceed one circle each time they are rotated and adjusted, so as to prevent the connection line of the electric push-pull rod 30 of the first air intake pipe 11 from being entangled. The flip transmission mechanism 8 can not only adjust the hole position of the casing piece 3, but also work in conjunction with the bundle integrated bundle 12. When the casing piece 3 rotates, the bundle integrated bundle 12 is fixed by the locking bolt 26 and will not rotate with the casing piece 3, but remain stationary. This design allows the bundle end 4 to gradually twist during the rotation of the casing piece 3, thereby enhancing the tightness of the bundle and further improving the sealing of the casing piece 3.

[0044] In this embodiment, the edible viscose is preferably gelatin. Gelatin is suitable for most types of casing repairs, including natural casings and artificial casings. Its good biocompatibility and transparency make it an ideal repair material, especially suitable for the food processing industry. Gelatin will dry quickly after heating to form a strong adhesive layer. This makes the repair process more efficient, shortens the repair time, and improves production efficiency. The dried gelatin has a certain flexibility and can adapt to the bending and stretching of the casing, reducing secondary damage caused by mechanical stress, which is very important for the filling and transportation of meat products such as sausages and ham. Combined with the hot air drying function in the present technical solution, gelatin can be dried quickly in a short time, further improving the speed and quality of the repair. The effect of hot air not only accelerates the drying of gelatin, but also enhances its bonding strength, ensuring that the repaired casing piece 3 can be put into use quickly.

[0045] Working principle:

[0046] The casing repair component elastically expands the sleeve joint portion 14 of the casing piece 3 and then sleeves it on the sleeve positioning portion 13 of the repair sleeve piece 2. A sealing fastener 6 is used, including a fastening internal threaded sleeve 18 and a fastening wrapping sleeve 17, which is threadedly connected to the repair sleeve piece 2 through an external threaded path 16 to ensure that the casing piece 3 is tightly connected to the repair sleeve piece 2. A silicone sealing gasket 15 is sleeved on the outer wall of the sleeve joint portion 14 to enhance the sealing and friction force and prevent the casing piece 3 from falling off. A tying rope is used to tie and seal the end of the casing piece 3 away from the repair sleeve piece 2 to form a tying end 4, and a tying integrated bundle portion 12 is reserved. The tying integrated bundle portion 12 is placed in the integrated bundle accommodating hole 25 at the other end of the U-shaped bracket 1, and is squeezed and limited by a locking bolt 26 to ensure that the casing piece 3 remains in a horizontal state.

[0047] The beginning of the first air inlet pipe 11 is connected to the air compressor gun, and the gas enters the interior of the repair sleeve 2 through the first air inlet pipe 11. The two branch air pipes 34 at the end of the first air inlet pipe 11 are used to inflate the casing 3 and the repair annular inner support airbag 29. One branch air pipe 34 directly inflates the casing 3 to expand and expose the hole; the other branch air pipe 34 is connected to the repair annular inner support airbag 29 through the air hose 31, but it is not inflated at this time.

[0048] The servo motor 23 is started to drive the driving gear 22 to rotate, and the driving gear 22 is meshed with the driven gear 21, driving the repair sleeve 2 and the casing 3 to rotate. The rotation angle of the servo motor 23 is controlled by operating the radio frequency transmitter remote control, and the hole to be repaired is adjusted to a convenient position for operation (usually an upward position) for subsequent repair operations. During the rotation of the casing 3, the repair annular inner support airbag bag 29 and the repair annular outer support airbag bag 5 are in an unexpanded state to avoid interference.

[0049] The electric push-pull rod 30 is opened and extended to extend the load-bearing support rod 28 and the repair annular inner support airbag 29 to the hole inside the casing 3. The repair annular inner support airbag 29 is inflated through the air delivery hose 31 to expand it. When inflated, the expanded fold friction part 32 of the outer wall of the repair annular inner support airbag 29 moves away from each other along the directions of arrows a and b, expanding the folds around the hole and exposing the hole, preparing for subsequent repair.

[0050] After the repair annular inner support airbag bag 29 stretches the wrinkles around the hole, manually apply glue to stick the hole patch on, and manually move the repair annular outer support airbag bag 5 to a position aligned with the repair annular inner support airbag bag 29. Ensure that the repair annular outer support airbag bag 5 can accurately cover the hole and its patch area. Connect the second air inlet pipe 19 to the external air pump and hot air blower, and input hot air into the repair annular outer support airbag bag 5 through the second air inlet pipe 19. After the repair annular outer support airbag bag 5 expands, its outer support inner ring 20 tightly wraps the casing 3 and the hole patch to provide external support. The hot air provided by the hot air blower not only expands the repair annular outer support airbag bag 5, but also transfers heat to the hole patch, accelerating the drying and bonding process of the edible glue. The repair annular inner support airbag 29 expands inside the casing piece 3 to support the inside of the hole; the repair annular outer support airbag 5 expands outside the casing piece 3 to wrap the hole patch. The inner and outer clamping support design ensures that the hole patch fits tightly to the casing piece 3, enhancing the stability and firmness of the repair. Under the action of hot air, the edible viscose of the hole patch dries quickly, further improving the quality and stability of the repair.

[0051] After the repair is completed, the gas discharge is controlled by the solenoid valve 35, and the air is gradually deflated to restore the repaired annular inner support airbag bag 29 and the repaired annular outer support airbag bag 5 to their original state. The electric push-pull rod 30 contracts to retract the repaired annular inner support airbag bag 29 to its initial position, remove the sealing fastener 6, and take off the casing 3 to complete the entire repair process.
