Description

Technical Field

[0001] The present invention relates to the technical field of heat exchangers, and in particular to a detachable wide-channel plate heat exchanger. Background Art

[0002] A plate heat exchanger is a highly efficient heat exchanger composed of a series of stacked, corrugated metal plates. Thin rectangular channels are formed between the plates, through which heat is exchanged. Plate heat exchangers are ideal for liquid-to-liquid and liquid-to-vapor heat exchange. They offer high heat transfer efficiency, minimal heat loss, a compact and lightweight structure, a small footprint, wide application, and a long service life.

[0003] At present, the existing Chinese patent number: CN218600358U discloses a detachable wide-channel plate heat exchanger, including a first movable pressing plate, a plurality of connection interfaces are provided on the outer side of the first movable pressing plate, a side of the first movable pressing plate away from the connection interface is connected to a heat transfer plate, a side of the heat transfer plate away from the first movable pressing plate is connected to a second movable pressing plate, a side of the second movable pressing plate away from the heat transfer plate is connected to a guide rod, a plurality of plug-in rods are internally connected between the first movable pressing plate and the second movable pressing plate, a plurality of detachable connection structures are provided at the outer ends between the first movable pressing plate and the second movable pressing plate, a detachable connection structure is provided on the wide-channel plate heat exchanger, and the first movable pressing plate, the second movable pressing plate and the heat transfer plate can be quickly separated by the detachable connection structure, thereby achieving the purpose of repairing the heat transfer plate.

[0004] The existing Chinese patent number CN208704502U discloses a detachable wide-channel plate heat exchanger, comprising a base, a fixed clamping plate, and a guide rod. The fixed clamping plate is fixedly welded to one end of the upper surface of the base, and the guide rod is fixedly connected to the fixed clamping plate by a thread. There are two sets of guide rods, and a screw rod is fixedly provided at the bottom of the guide rod, and one end of the screw rod is fixedly connected to the fixed clamping plate. The utility model is convenient for users to clean and increase or decrease the number of heat exchange plates during use by making the heat exchange plate detachable. The heat exchange plate is of a wide-channel type, which can effectively increase the exchange efficiency. After the exchange is completed, the gas is discharged through the air outlet. The water inlet, water outlet, air inlet, and one end of the air outlet are fixedly connected with a quick-connect valve, so that the connecting pipes can be quickly disconnected, which is very convenient to disassemble. It is combined with the base for easier movement and is suitable for widespread promotion and use.

[0005] However, during the implementation of the above technical solution, at least the following technical problems were found:

[0006] The disassembly structure is cumbersome and requires a major modification to the original side-by-side heat exchanger: The existing detachable plate heat exchangers are mainly divided into two types. One is to change the original connection structure into a detachable structure. This structure not only requires the manufacture of devices with specific structures, but also cannot be applied to the existing plate heat exchangers, resulting in very large limitations in the implementation of the structure. The other is to change the structure of the plate into a structure that is convenient for replacement. This method not only requires the modification of the original structure of the plate heat exchanger, but also the preparation of structures with specific structures and shapes, making the implementation of this structure more difficult. Therefore, we propose a detachable wide-channel plate heat exchanger. Summary of the Invention

[0007] (I) Technical Problems to be Solved

[0008] Aiming at the deficiencies of the prior art, the present invention provides a detachable wide-channel plate heat exchanger to solve the technical problems that the existing detachable plate heat exchangers are cumbersome in disassembly structure and require a major modification to the original side-by-side heat exchanger when in use.

[0009] (II) Technical Solutions

[0010] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0011] A detachable wide-channel plate heat exchanger, which includes a bracket directly composed of three square tubes, shaped like a "匚" shape. A front baffle and a rear baffle are installed in the opening of the bracket. The front baffle is fixedly connected to the front end of the bracket, thus forming an integral body with the bracket. The rear baffle is installed in the opening of the bracket, and both its upper and lower ends have sliding grooves. During the sliding process, the rear baffle is slidably connected to the outer wall of the bracket through the sliding grooves, so that the rear baffle can slide in the bracket to conveniently adjust the position of the rear baffle. This is also for the convenience of adaptive adjustment according to the number of plates. The above structures are all conventional structures of existing plate heat exchangers. The main technical improvement of this application lies in: A movable plate is hinged on the outside of the front baffle. This movable plate is like a hinge and can rotate outside the front baffle. A connecting rod is connected to the outside of the movable plate. One end of the connecting rod is threadedly connected to the movable plate. Therefore, when the movable plate rotates, it can带动 the connecting rod to rotate together, making the connecting rod enter the embedding groove on the outside of the rear baffle. Then, a nut can be used to fix the connecting rod to the device. Since when the plate heat exchanger is fixed, the connecting rod needs to exert a force on the front baffle in the direction of the rear baffle, the force on the movable plate is also towards the front baffle. Therefore, there is no need to worry about the stability and safety of the device fixation. Moreover, there is no need to make too many modifications to the existing plate heat exchangers, thus facilitating the application of this improvement to the existing devices, thereby improving the feasibility of the device.

[0012] A bracket in a "匚" shape, with a front baffle and a rear baffle corresponding to each other in the front and back installed at its opening, and the rear baffle can slide in the opening of the bracket to maintain the stability of the position between the front baffle and the rear baffle;

[0013] A connecting piece, connected to the front baffle, and the front baffle is connected to the rear baffle through the connecting piece in order to connect the front baffle and the rear baffle together;

[0014] Among them, a plurality of plates are clamped between the front baffle and the rear baffle, and the medium exchanges heat between the plates;

[0015] The connecting piece includes a movable plate hinged to the outer wall of the front baffle, and a connecting rod is connected to the outside of the movable plate. The connecting rod can rotate in the direction of the rear baffle, so that the connecting rod and the front baffle form a whole, thus reducing the subsequent connection difficulty;

[0016] A nut is connected to the outside of the connecting rod. When the connecting rod fits with the rear baffle, the nut on the outside of the connecting rod can clamp the rear baffle. In order not to make too many improvements to the structure of the connecting rod, so as not to spend a lot of time improving when the existing plate heat exchanger uses this technology, the original nut is still used. However, the difference is that an oval long rod is connected between these two nuts, and the long rod is inserted into the collar on the outside of the nut, and the inner wall of the collar fits with the outer wall of the long rod. In this way, the two nuts cannot rotate relative to each other first and can only move back and forth. Therefore, when rotating the connecting rod, it can drive the two nuts to move, making the nuts move back and forth along the connecting rod mechanism.

[0017] Preferably, embedding grooves are provided at the edges of the front baffle and the rear baffle, and the movable plates correspond to the embedding grooves on the outside of the front baffle one by one, which is convenient for the connecting rod on the movable plate to accurately enter the embedding groove on the front baffle when rotating the movable plate;

[0018] Among them, when the movable plate moves towards the outer wall of the front baffle, the connecting rod can be embedded into the embedding groove outside the rear baffle, enabling the connecting rod to quickly and stably enter the embedding groove, that is, changing from the shape shown in the figure to the shape shown in the figure.

[0019] Preferably, the embedding groove is divided into two parts, one part is a circular through hole, and the other part is a rectangular through hole. This is to facilitate the connecting rod to enter the circular through hole, and at the same time, when the nut is connected to the device, it can enter the circular through hole;

[0020] Among them, the width of the rectangular through hole is the same as the outer diameter of the connecting rod, and one end of the connecting rod extends to the edge of the rear baffle, and the other end extends to the circular through hole, and its inner diameter is greater than the width of the rectangular through hole.

[0021] Preferably, the number of the nuts is two groups, which can clamp the rear baffle from both sides of the rear baffle, and the spiral directions of the internal threads of the two nuts are opposite, so that when the connecting rod is rotated, the two nuts can be driven to open and close at the same time;

[0022] Wherein, the side of the nut facing the rear baffle is connected to a limiting tube, and the nut can be inserted into the circular through hole of the embedding groove through the limiting tube, thereby maintaining the stability of the connection between the nut and the rear baffle.

[0023] Preferably, the outer wall of the plate is provided with four through holes, and the through holes between two adjacent plates correspond to each other to form a medium channel;

[0024] Among them, the outer wall of the front baffle is connected to a pipe, and the front baffle is connected to the medium channel formed by the plate through the pipe. The heat exchange principle of the plate heat exchanger is that the cold and hot media enter different channels through different pipes, and then enter the gap between the plates through the channels. At this time, the cold and hot media are respectively located on both sides of the plate, and heat exchange is carried out through the plate.

[0025] Preferably, a connecting piece is provided on the side of the rear baffle facing the front baffle, and the connecting piece is located in the medium channel formed by the plates, that is, the channel that the medium enters before entering between two adjacent plates;

[0026] The connecting piece includes a connecting pipe, and a traction rope is connected to each side of the connecting pipe. The traction rope can be used to pull the connecting pipe to move in the medium channel, thereby adjusting the position of the connecting pipe so that the connecting pipe moves to a specified position, and the plate covered by the connecting pipe is blocked so that the medium does not pass through this part of the plate. In this way, when the plate leaks the medium or a problem occurs, an emergency connection can be made to avoid the need to shut down the entire line.

[0027] Preferably, the connecting piece further comprises a traction portion and a connecting portion corresponding to each other, and the connecting portion is connected to the pipe outside the front baffle, and the traction portion is connected to the outer wall of the rear baffle, so as to facilitate the connecting pipe to move back and forth between the front baffle and the rear baffle;

[0028] Wherein, a driver is installed inside the traction part, which can retract and release the traction rope, thereby providing a power source for the movement of the connecting pipe.

[0029] Preferably, the traction part includes a turntable, and the front end of the turntable is connected to a winding roller 1, and one end of the traction rope is wound around the outside of the winding roller 1;

[0030] Among them, a motor is installed inside the turntable, and the motor can drive the winding roller to rotate. Therefore, when the motor rotates, it can drive the connecting pipe to move in the direction of the winding roller, thereby providing power for the movement of the connecting pipe.

[0031] Preferably, the connecting portion includes a connecting piece, and a second winding roller is installed inside the connecting piece;

[0032] Among them, the end of the traction rope away from the rear baffle is connected to the winding roller 2, and the winding roller 2 is connected to the connecting piece through a torsion spring. When the traction rope is not under force, the winding roller 2 can reel in the traction rope under the action of the torsion spring, thereby cooperating with the motor to drive the connecting pipe to move forward and backward, thereby freely adjusting the position of the connecting pipe.

[0033] Preferably, there are two connecting pieces, and opposite sides of the two connecting pieces are connected to an insert rod via a spring, so that by pressing the two connecting pieces, the two connecting pieces can be moved relative to each other, thereby reducing the distance between the two connecting pieces and facilitating removal from the pipeline;

[0034] The edge of the connecting piece is in an "L" shape, which can be connected to the pipe mouth of the pipe, making it convenient to hook the pipe so that the connecting piece and the pipe mouth are connected together.

[0035] (3) Beneficial effects

[0036] 1. Since the connecting rod is driven to move by rotation and the front and rear baffles are fixed by the nut on the connecting rod, the technical problem of the existing detachable plate heat exchanger being cumbersome to disassemble during use and requiring a substantial modification of the original accompanying heat exchanger is effectively solved. This increases the detachability of the device without changing the original plate heat exchanger structure, thereby improving the feasibility and economy of the device.

[0037] 2. Since a driver is used to pull the traction rope, the connecting pipe on the traction rope is blocked at the leaking plate heat exchanger. Therefore, the technical problem that the existing detachable plate heat exchanger cannot perform emergency treatment on the leaking plate heat exchanger when in use is effectively solved, thereby realizing temporary adjustment of the plate heat exchanger and avoiding the need for emergency stop of related devices, thereby improving the stability and safety of the device.

DETAILED DESCRIPTION

[0052] Embodiments of the present application provide a detachable wide-channel plate heat exchanger, effectively solving the technical problems that the existing detachable plate heat exchanger has a cumbersome disassembly structure and requires a large-scale modification of the original accompanying heat exchanger. When the existing detachable plate heat exchanger is in use, since the rotation method is adopted to drive the connecting rod to move, and then the front and rear baffles are fixed by the nuts on the connecting rod, the detachable property of the device is increased without changing the structure of the original plate heat exchanger, thereby improving the feasibility and economy of the device; since the driver is used to pull the traction rope, the connecting pipe on the traction rope plugs at the leaking plate heat exchanger, thereby realizing the temporary adjustment of the plate heat exchanger and avoiding the need for relevant devices to stop urgently, thereby improving the stability and safety of the device during use. Embodiment 1

[0053] The technical solution in the embodiments of the present application effectively solves the technical problems that the existing detachable plate heat exchanger has a cumbersome disassembly structure and requires a large-scale modification of the original accompanying heat exchanger. The general idea is as follows:

[0054] In view of the problems existing in the prior art, the present invention provides a detachable wide-channel plate heat exchanger. The plate heat exchanger includes a bracket 1, which is directly composed of three square pipes and has a shape like a "匚" shape. A front baffle 2 and a rear baffle 3 are installed in the opening of the bracket 1. The front baffle 2 is fixedly connected to the front end of the bracket 1, thus forming an integral body with the bracket 1. The rear baffle 3 is installed in the opening of the bracket 1, and both its upper and lower ends have chutes. During the sliding process, the rear baffle 3 is slidably connected to the outer wall of the bracket 1 through the chutes, so that the rear baffle 3 can slide in the bracket 1, which is convenient for adjusting the position of the rear baffle 3. This is also to facilitate the adaptive adjustment according to the number of plate sheets 4. The above structures are all conventional structures of the existing plate heat exchanger. The main technical improvement of the present application lies in: by hinging a movable plate 51 on the outside of the front baffle 2. The movable plate 51 is like a hinge and can rotate outside the front baffle 2, as Figure 4 shown. A connecting rod 52 is connected to the outside of the movable plate 51 (the connecting rod 52 can use the threaded rod in the existing plate heat exchanger). One end of the connecting rod 52 is threadedly connected to the movable plate 51. Therefore, when the movable plate 51 rotates, it can带动 the connecting rod 52 to rotate together, so that the connecting rod 52 enters the embedding groove on the outside of the rear baffle 3, as Figure 1 shown. Then, the connecting rod 52 can be fixed to the device using a nut 53. Since the plate heat exchanger needs the connecting rod 52 to exert a force on the front baffle 2 in the direction of the rear baffle 3 when it is fixed, the force on the movable plate 51 is also towards the front baffle 2. Therefore, there is no need to worry about the stability and safety of the device during fixation. Moreover, there is no need to make too many modifications to the existing plate heat exchanger, so it is convenient to apply this improvement to the existing device, thereby improving the feasibility of the device.

[0055] The bracket 1 in a "匚" shape has a front baffle 2 and a rear baffle 3 installed at the front and rear corresponding positions at its opening, and the rear baffle 3 can slide in the opening of the bracket 1, as Figure 1 and Figure 5 shown, so as to maintain the stability of the position between the front baffle 2 and the rear baffle 3;

[0056] The connecting member 5 is connected to the front baffle 2, and the front baffle 2 is connected to the rear baffle 3 through the connecting member 5 in order to connect the front baffle 2 and the rear baffle 3 together;

[0057] Among them, a plurality of plates 4 are clamped between the front baffle 2 and the rear baffle 3, and the medium exchanges heat between the plates 4;

[0058] The connecting member 5 includes a movable plate 51 hinged to the outer wall of the front baffle 2, as Figure 4 shown, and a connecting rod 52 is connected to the outside of the movable plate 51. The connecting rod 52 can rotate in the direction of the rear baffle 3, as Figure 1 and Figure 2 shown, so that the connecting rod 52 and the front baffle 2 form a whole, and the subsequent connection difficulty can be reduced;

[0059] A nut 53 is connected to the outside of the connecting rod 52. When the connecting rod 52 is in contact with the rear baffle 3, the nut 53 outside the connecting rod 52 can clamp the rear baffle 3. In order not to make too many improvements to the structure of the connecting rod 52, so as not to spend a lot of time improving when the existing plate heat exchanger uses this technology. Therefore, the original nut 53 is still used, but the difference is that an oval long rod 55 is connected between the two nuts 53 (only a non-cylindrical rod structure can be used to prevent the two nuts 53 from rotating relative to each other), and the long rod 55 is inserted into the collar 54 outside the nut �, and the inner wall of the collar 54 fits with the outer wall of the long rod 55, as Figure 5 shown, so that the two nuts 53 cannot rotate relative to each other first and can only move back and forth. Therefore, when the connecting rod 52 rotates, it can drive the two nuts 53 to move, and the nuts 53 move back and forth along the connecting rod 52

[0060] In some examples, embedding grooves are provided at the edges of the front baffle 2 and the rear baffle 3, as Figure 2 and Figure 4 shown, and the movable plates 51 correspond to the embedding grooves on the outside of the front baffle 2 one by one, which is convenient for the connecting rod 52 on the movable plate 51 to accurately enter the embedding groove on the front baffle 2 when the movable plate 51 rotates;

[0061] When the movable plate 51 moves toward the outer wall of the front baffle 2, the connecting rod 52 can be embedded in the embedding groove outside the rear baffle 3, so that the connecting rod 52 can quickly and stably enter the embedding groove. Figure 2 become Figure 1 Shape shown.

[0062] In some examples, the embedded slot is divided into two parts, one part is a circular through hole and the other part is a rectangular through hole, such as Figure 4 As shown, this is to facilitate the connecting rod 52 to enter the circular through hole, and at the same time, when the nut 53 is connected to the device, it can enter the circular through hole;

[0063] The width of the rectangular through hole is consistent with the outer diameter of the connecting rod 52, and one end of the connecting rod 52 extends to the edge of the rear baffle 3, and the other end extends to the circular through hole, whose inner diameter is greater than the width of the rectangular through hole. Figure 4 shown.

[0064] In some examples, the number of nuts 53 is two sets, which can clamp the rear baffle 3 from both sides of the rear baffle 3, and the spiral directions of the internal threads of the two nuts 53 are opposite, such as Figure 1 and Figure 5 As shown, in order to simultaneously drive the two nuts 53 to perform opening and closing movements during the rotation of the connecting rod 52;

[0065] Among them, the nut 53 is connected to the side of the rear baffle 3 with a limiting tube, and the nut 53 can be inserted into the circular through hole of the embedding groove through the limiting tube, such as Figure 5 As shown, the stability of the connection between the nut 53 and the rear baffle 3 is maintained.

[0066] In some examples, four through holes are formed on the outer wall of the plate 4, and the through holes between two adjacent plates 4 correspond to each other to form a medium channel;

[0067] Among them, the outer wall of the front baffle 2 is connected to a pipe, and the front baffle 2 is connected to the medium channel formed by the plate 4 through the pipe. According to the heat exchange principle of the plate heat exchanger, the cold and hot media enter different channels through different pipes, and then enter the gap between the plates 4 through the channels. At this time, the cold and hot media are respectively located on both sides of the plate 4, and heat exchange is carried out through the plate 4.

[0068] In the specific implementation process, when installing, first place the plate 4 to be installed between the front baffle 2 and the rear baffle 3, then rotate the movable plate 51. Since the connecting rod 52 is connected to the movable plate 51, the connecting rod 52 can rotate synchronously during the rotation of the movable plate 51, thereby entering the embedded grooves on the outside of the front baffle 2 and the rear baffle 3, and making the two nuts 53 on the connecting rod 52 distributed on the front and rear sides of the rear baffle 3, and then insert the long rod 55 into the collar 54 outside the two nuts 53, as shown in FIG. Figure 5As shown, after completion, the connecting rod 52 is rotated. Since the two nuts 53 on the connecting rod 52 are located on both sides of the rear baffle 3, and the screw threads inside the two nuts 53 are in opposite directions and are connected by a long rod 55, they cannot rotate relative to each other. Therefore, when the connecting rod 52 is rotated, the two nuts 53 can be driven to open and close, thereby clamping the rear baffle 3 located between the two nuts 53, thereby completing the fixation of the device. Similarly, when opening, it is only necessary to rotate the connecting rod 52 in the opposite direction so that the two nuts 53 move away from the rear baffle 3. After that, the connecting rod 52 can be rotated with the movable plate 51 as the axis to open the connecting rod 52. Figure 2 As shown, the plate 4 on the device can be replaced or adjusted at this time. Example 2

[0069] Based on Example 1, this embodiment of the present application provides a method for quickly adjusting a plate heat exchanger when a plate at a local location is damaged, thereby improving the safety of the device. The overall concept is as follows:

[0070] A connecting piece 6 is provided on the side of the rear baffle 3 facing the front baffle 2, and the connecting piece 6 is located in the medium channel formed by the plates 4, that is, the channel that the medium enters before entering between two adjacent plates 4;

[0071] Among them, the connecting piece 6 includes a connecting pipe 63 (the connecting pipe 63 is divided into two parts, one is a bellows 631; the other is a retaining ring 632 connected to the bellows 631, and the retaining rings 632 at both ends of the bellows 631 are respectively connected to two groups of different traction parts 61), and a traction rope 64 is connected to each side of the connecting pipe 63. The traction rope 64 can be used to pull the connecting pipe 63 to move in the medium channel, thereby adjusting the position of the connecting pipe 63 so that the connecting pipe 63 moves to the specified position, and the plate 4 covered by the connecting pipe 63 is blocked, so that the medium does not pass through this part of the plate 4, so that when the plate 4 leaks the medium or a problem occurs, an emergency connection can be made to avoid the need to shut down the entire line.

[0072] In some examples, the connecting member 6 further includes a traction portion 61 and a connecting portion corresponding to each other, and the connecting portion is connected to the pipe outside the front baffle 2, and the traction portion 61 is connected to the outer wall of the rear baffle 3, so as to facilitate the connection pipe 63 to move back and forth between the front baffle 2 and the rear baffle 3;

[0073] A driver is installed inside the traction part 61 to retract and release the traction rope 64 , thereby providing a power source for the movement of the connecting tube 63 .

[0074] In some examples, the traction portion 61 includes a turntable 611 , and a winding roller 1 612 is connected to the front end of the turntable 611 , and one end of the traction rope 64 is wound around the outside of the winding roller 1 612 ;

[0075] Among them, a motor is installed inside the turntable 611, and the motor can drive the winding roller 612 to rotate. Therefore, when the motor rotates, it can drive the connecting tube 63 to move in the direction of the winding roller 612, thereby providing power for the movement of the connecting tube 63.

[0076] In some examples, the connecting portion includes a connecting piece 621 , and a second winding roller 622 is installed inside the connecting piece 621 ;

[0077] Among them, the end of the traction rope 64 away from the rear baffle 3 is connected to the winding roller 2 622, and the winding roller 2 622 is connected to the connecting piece 621 through a torsion spring. When the traction rope 64 is not under force, the winding roller 2 622 can reel in the traction rope 64 under the action of the torsion spring, thereby cooperating with the motor to drive the connecting tube 63 to move forward and backward, thereby freely adjusting the position of the connecting tube 63.

[0078] In some examples, there are two connecting pieces 621, and opposite sides of the two connecting pieces 621 are connected to an insert rod 623 via a spring. Thus, by pressing the two connecting pieces 621, the two connecting pieces 621 can move relative to each other, thereby reducing the distance between the two connecting pieces 621 and facilitating removal from the pipeline.

[0079] The edge of the connecting piece 621 is in an L-shape and can be connected to the pipe mouth of the pipe. Figure 8 and Figure 9 As shown, it is convenient to hook the pipe so that the connecting piece 621 is connected to the pipe mouth of the pipe.

[0080] During the specific implementation process, before use, press the two connecting pieces 621 so that the insertion rod 623 between the two connecting pieces 621 is retracted into the inside of the connecting piece 621, and then the connecting piece 621 is passed through one end of the pipe (again, pass through each plate 4 in turn before entering the other side of the pipe, and release the connecting piece 621. At this time, the insertion rod 623 between the two connecting pieces 621 moves outward under the action of the spring, so that the two connecting pieces 621 are unfolded, thereby hooking the pipe mouth of the pipe, thereby completing the connection between the connecting part and the pipe. At this time, the connecting pipe 63 arranged between the connecting part and the traction part 61 is located in the channel formed by the through hole on the outside of the plate 4.

[0081] When medium leakage or damage occurs between one or more plates 4, one of the winding rollers 612 on the same turntable 611 is controlled to rotate to reel in the traction rope 64, thereby pulling the retaining ring 632 at one end of the bellows 631 to move toward the fault location, and the device moves to the rightmost side of all fault locations. At this time, the motor is controlled to stop rotating. Similarly, another winding roller 612 on the same turntable 611 is controlled to rotate so that it drives the retaining ring 632 at the other end of the bellows 631 to move toward the fault location and move to the leftmost side of all fault locations, so that the bellows 631 covers all the fault locations. At this time, the plate 4 covered by the bellows 631 is blocked, so that the medium does not pass through this part of the plate 4, so that when the plate 4 leaks medium or a problem occurs, an emergency connection can be made, avoiding the need to stop the entire line and facilitating repairs and adjustments in spare time.

[0082] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
