Description

Technical Field

[0001] The utility model belongs to the field of separation of metal fibers produced by a cluster drawing method, in particular to an electrolytic cell system, a traveling support and fiber separation equipment. Background Art

[0002] The bundle drawing method for producing metal fibers is an important metalworking process. It assembles multiple metal wires coated with an insulating agent, fills them into a metal sleeve, and then continuously draws them through multi-stage drawing dies to produce metal fiber bundles with higher strength and smaller diameters (typically ranging from 1-2 microns to several hundred microns).

[0003] Fiber separation: It is the process of peeling off the metal material wrapped around the fiber bundle and the metal material wrapped around the single fiber as an isolation agent from the fiber body to obtain dispersed and independent metal fiber bundles. Fiber separation technology is a very important process technology for the production of metal fibers by the bundle drawing method. High efficiency, low cost, high quality and environmentally friendly fiber separation technology has always been the goal that the industry continues to pursue.

[0004] Existing fiber separation processes typically use strong acids, strong bases, and other electrolytes through electrochemical or immersion methods. Commonly used equipment includes discontinuous roller separation equipment and continuous inline separation equipment. The following briefly describes the characteristics of these two types of production equipment.

[0005] 1. Structure and production process of intermittent roller separation equipment:

[0006] On a horizontal cylindrical roller, the metal fiber composite wire is first manually wound on a horizontal stick, and the roller wrapped with the composite wire is immersed in an electrolyte tank containing a strong acid or a strong base. Direct current is passed through the stick, and it serves as an anode. After several hours of electrolysis or soaking, the metal jacket on the outer layer of the fiber bundle and the metal material of the separator on the surface of the fiber body are completely dissolved in the strong acid or strong base electrolyte solution. Then, the fiber bundle remaining on the cylindrical roller is manually removed from the stick to obtain a fiber bundle containing a large amount of strong acid or strong base, which is then sent to the next cleaning process to clean the strong acid or strong base remaining on the surface of the fiber bundle, thereby obtaining a fiber bundle.

[0007] Features of intermittent roller separation equipment:

[0008] Advantages: Direct current is directly input from the power supply to the roller, making the composite wire positively charged and acting as the anode. The current returns to the cathode plate through the electrolyte solution and then returns to the negative electrode of the power supply. The advantage of this process is high current utilization efficiency;

[0009] shortcoming:

[0010] 1. First, during manual operation, workers are inevitably exposed to strong acids or alkalis, which brings potential dangers to operators. In addition, the workers are frequently put on and off the production line, which takes a long time and is labor-intensive.

[0011] 2. During the unloading process of the fiber bundle, strong acid or alkali may splash out and contaminate the workplace floor;

[0012] 3. Due to the structural characteristics of the roller separation equipment, it is difficult to fully seal the electrolytic cell. As a result, the harmful gases generated in the electrolytic cell during the fiber separation process will overflow into the workshop and cause harm to the environment.

[0013] 4. The separation process and cleaning process separate different work locations, thereby reducing work efficiency.

[0014] 2. The structure of the continuous linear separation equipment: It consists of a continuous power pay-off unit, a continuous linearly arranged extra-long cathode and anode interchangeable electrolytic cell group, an online cleaning tank group, an online hot drying unit, a fiber bundle active winding unit and other solution circulation systems and acid mist treatment systems. The equipment is arranged in a continuous linear manner and the entire production line is extra-long (usually more than 100 meters long).

[0015] Continuous linear separation production process: The composite wire containing the fiber bundle is sequentially sent from the active pay-off unit into the ultra-long electrolytic cell for electrolysis or immersion. The fiber bundle jacket and separator are dissolved into the electrolyte solution. The fiber bundle then continues to move forward into the cleaning tank. After online cleaning to completely remove the residual solution, it enters the continuous drying unit to remove moisture from the surface of the fiber bundle. Finally, it is collected by the active winding unit.

[0016] Features of continuous linear separation equipment:

[0017] Advantages: Operators have less chance of coming into contact with strong acids or alkalis, and the potential danger is low; the entire production equipment realizes continuous operation of fiber separation and cleaning, reducing operators' manual work and labor intensity; harmful gases and residual acid are effectively controlled, and the environment is relatively friendly.

[0018] shortcoming:

[0019] 1. During the electrolysis process, the current starts from the power supply, first passes through the anode plate of the anode electrolytic cell and is transmitted to the electrolyte solution therein, then is transmitted along the composite line to the composite line in the cathode electrolytic cell. In the cathode electrolytic cell, the current again enters the electrolyte solution through the composite line, reaches the cathode plate of the cathode cell, and then returns to the power supply. The current transmission process is repeated, and the current is indirectly transmitted to the composite line with the help of the electrolyte solution instead of directly transmitted to the composite line, resulting in high power supply voltage of the electrolytic cell, high energy consumption, and reduced current efficiency.

[0020] 2. The entire production line is too long, requiring large investment and occupying a large area, resulting in low unit output. Utility Model Content

[0043] The above structure has the following advantages:

[0044] 1. The electrolytic cell system of this application has the following advantages:

[0045] a. The electrolytic cell system is provided with a liquid inlet, a liquid outlet and an overflow port. In this way, after the titanium barrel is placed in the electrolytic cell body, the electrolyte can be introduced from the liquid inlet, thereby reducing the loss and pollution of the electrolyte stored in the electrolytic cell. During the reaction process, the concentration of the acid in the electrolyte decreases. The electrolyte in the electrolytic cell is replaced through the cooperation of the overflow port and the liquid inlet, thereby continuously ensuring the activity state of the electrolyte. When the electrolysis is completed, the electrolyte in the electrolytic cell body is discharged in time to reduce the electrolyte residue on the product and facilitate the subsequent process.

[0046] b. The electrolytic cell system is provided with an exhaust port, so that the acid mist gas generated during the fiber separation process overflows from the electrolyte in the closed electrolytic cell body and is sucked away by the gas purification system above the cell body, and is treated by the purification tower to achieve harmless treatment.

[0047] c. The anode plate in the electrolytic cell body also serves as the anode platform for supporting the titanium barrel. When the titanium barrel is placed on the anode platform of the electrolytic cell body, the anode platform not only supports the titanium barrel and the composite wire wrapped around it, but also takes on the task of transmitting the anode current to the titanium barrel. The titanium barrel is directly placed on the anode platform, and the weight of the titanium barrel itself and the combined weight of the composite wire on it act on the anode platform. By designing the contact area between the anode platform and the titanium barrel, it is ensured that the titanium barrel and the anode platform are in full contact. When power is applied, the conductive resistance is small, which meets the power transmission requirements. At the same time, the operation process of lifting and placing the titanium barrel becomes very convenient.

[0048] 2. The walking support of this application has the following advantages:

[0049] a. During the lifting and lowering operation, the lifting platform of the present application adopts multiple vertical, mutually parallel precision guide rods to ensure that the lifting platform is always accurately positioned on the central axis of the lifting platform during the rising and falling process. At the same time, the position of the lifting platform moving up and down is located by a position sensor, which includes a first position sensor, a second position sensor and a third position sensor. The first position sensor is installed on the first movable support beam, the second position sensor is installed on the second movable support beam, and the third position sensor is installed on the door frame and placed below the second movable support beam. The first position sensor is used to monitor whether the lifting platform has reached the position on the first movable support beam. The first position sensor controls the movement of the first movable support beam, so that the lifting platform can be accurately supported on the first movable support beam when in the walking state; the second position sensor monitors whether the lifting platform has reached the position on the second movable support beam. The second position sensor controls the movement of the second movable support beam, so that the lifting platform can be accurately supported on the second movable support beam when in the drying state; the third position sensor is used to monitor the position of the lifting platform and control the opening and closing of the mechanical gripper, so as to accurately place the titanium barrel into the electrolytic cell body or the cleaning tank or accurately grab the titanium barrel from the electrolytic cell body or the cleaning tank.

[0050] b. The spin-drying mechanism of the present application cooperates with a mechanical clamp, and the mechanical clamp adopts a three-claw sliding chuck, which is provided with three claws. During the spin-drying process, the weight of the rotating part includes the weight of the titanium barrel itself, the metal fiber on the titanium barrel, the three-claw sliding chuck and the passive gear, so the total weight is relatively large. In order to prevent the eccentricity of the center of gravity of the rotating part during spin-drying and generate additional centrifugal force, the weight of the chuck is distributed more evenly along the circumferential direction by setting three claws to ensure the stability of the system during spin-drying.

[0051] c. In the present application, since the lifting platform drives the titanium barrel to realize two actions, namely, moving and drying, in order to ensure the stability of the lifting platform during drying and walking, the present application sets a first movable support beam and a second movable support beam with the same structure on the door frame. The first movable support beam and the second movable support beam both include a movable crossbeam and a crossbeam driving mechanism for driving the movable crossbeam to move horizontally. The movable crossbeam can be driven to move on the guide rail by the action of the fourth servo motor. When the lifting platform moves to the walking support station or the drying support station, the four servo motor drives the two movable crossbeams to be relatively close to each other and enter under the lifting platform, so that the lifting The lowering platform falls on the moving beam, and the huge weight of the lifting platform is no longer borne by the steel rope of the lifting equipment, but is transferred to the gantry through the moving beam, thereby releasing the load of the steel rope of the lifting equipment; in the spin-drying state, it cooperates with the guide rod to ensure that the huge centrifugal force generated by the rotation of the titanium barrel during spinning will not affect the stability of the lifting platform, so that the spinning process proceeds smoothly; in the walking state, it also reduces the impact of the inertia of the lifting platform on the four guide rods, greatly improving the stability of the system during operation; and when switching between the walking state and the spin-drying state, the fourth servo motor is used to drive the moving beam to move accordingly.

[0052] 3. The fiber separation equipment of this application has the following advantages:

[0053] a. First, the electrolytic cell system and the traveling support of the fiber separation equipment have all the advantages of the electrolytic cell system and the traveling support, and the traveling support automatically realizes the whole process of electrolysis and cleaning of the composite wire to be electrolyzed wrapped around the titanium tube, without the need for human intervention and intervention, thereby ensuring the safety of the operators, reducing the number of operators, and improving labor productivity.

[0054] b. The walking bracket is installed on the walking track. Since the walking bracket itself is heavy, it not only needs to be moved, but also the titanium barrel needs to be dried, which requires high stability of the walking mechanism. Therefore, on the one hand, this application ensures the synchronization of the active walking mechanism on the two front legs of the door frame through a coupling drive mechanism. On the other hand, a pre-tightening force is given between the first gear and the first rack through a pre-tightening stabilization mechanism, so as to ensure that the gear and rack are always engaged when the active walking mechanism moves forward and backward on the walking track, thereby ensuring smooth and stable walking.

[0055] In summary, this device winds the composite wire around the outside of the titanium barrel. By combining the traveling bracket with the electrolytic cell system and the cleaning tank, the composite wire wound around the titanium barrel can be automatically electrolyzed and cleaned. No manual intervention is required during the entire process, thus ensuring the safety of the operator. BRIEF DESCRIPTION OF THE DRAWINGS

[0077] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0078] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0079] like Figures 14 to 16 As shown, the utility model provides an electrolytic cell system 3, including multiple sets of electrolytic cell bodies 31, liquid inlet and return systems 34 and gas purification systems 33. The top of the electrolytic cell body 31 is provided with an inlet and outlet that match the size of the titanium barrel 5.

The bottom of the electrolytic cell body 31 is fixed with an anode plate to form an anode platform supporting the titanium barrel 5. The top surface of the anode platform is horizontal and not less than the size of the bottom surface of the titanium barrel 5. The four sides of the electrolytic cell body 31 are respectively fixed with vertically arranged cathode plates 36. The inside of the electrolytic cell body 31 is A cathode power supply connection 35 and an anode power supply connection 38 are provided on the wall above the highest liquid level. The cathode power supply connection 35 is electrically connected to the cathode plate 36, and the anode power supply connection 38 is electrically connected to the anode plate. A liquid inlet 314 is provided in the middle of the bottom surface of the electrolytic cell body 31, and a liquid outlet 312 is provided at the lowest point of the bottom surface. An overflow trough is provided on the inner wall of the electrolytic cell body 31, and the inlet of the overflow trough matches the position of the highest liquid level in the electrolytic cell body 31. An overflow port 313 is provided at the bottom of the overflow trough on the side wall of the electrolytic cell body 31.

At the same time, the gas purification system 33 is turned on to continuously pump gas. The electrolyte in the electrolytic cell body 31 is discharged back to the solution pool 344 through the overflow port 313. When the set time is reached, the liquid discharge pump works to pump out the electrolyte in the electrolytic cell body 31 to complete the electrolysis process.

[0083] During electrolysis, the anode platform not only supports the titanium barrel 5 and the composite wire 55 wound around it, but also carries the anode current to the barrel 5. In this embodiment, the anode platform is a circular base 6 made of titanium-clad copper. The barrel 5 is placed directly on the anode platform, without any other auxiliary means. The combined weight of the barrel 5 and the composite wire 55 acting on the anode platform is directly applied to the anode platform. The contact area between the anode platform and the barrel 5 is designed to ensure sufficient contact between the barrel 5 and the anode platform, resulting in low electrical resistance when energized, meeting power transmission requirements. This also makes the lifting and lowering of the barrel 5 very convenient. For example, the anode platform has a diameter of 250-300 mm, a thickness of 5-10 mm, and an operating voltage of 1.0 V. Monitoring indicates that the current transmitted during operation is 60-120 A, which meets electrolysis requirements. During operation, the current flows in the following direction: anode power supply connection point → anode base 637 → barrel 5 → composite wire containing fiber bundles → electrolyte → cathode plate 36 → cathode power supply connection point.

[0084] like Figure 17 、 18As shown, in this embodiment, the titanium barrel 5 includes a cylinder, a titanium tube 53, an upper retaining edge 52 and a lower retaining edge 56. The cylinder is a truncated cone-shaped cylinder with an outer diameter at the bottom end larger than an outer diameter at the top end. A clamping ring 51 is installed on the top of the cylinder to facilitate clamping of the mechanical clamp 17. Through holes are evenly opened on the side wall of the cylinder. An upper retaining edge 52 and a lower retaining edge 56 are coaxially fixed on the outer sides of the two ends of the cylinder. A plurality of titanium tubes 53 are fixed on the outer wall of the cylinder between the upper retaining edge 52 and the lower retaining edge 56. The plurality of titanium tubes 53 are evenly arranged along the central axis of the cylinder, and a single titanium tube 53 is arranged along the busbar of the outer wall of the cylinder. The composite wire 55 to be electrolyzed is wound around the outside of the titanium tube 53. A gap 57 is formed between the wound composite wire 55 and the cylinder through the titanium tube 53. The cylinder, titanium tube 53, upper retaining edge 52 and lower retaining edge 56 are all made of titanium material.

[0085] During operation, the composite wire 55 containing metal fibers is evenly wound on the titanium tube 53 between the outer side, upper and lower edges of the titanium barrel 5 in advance to form a composite wire layer with uniform thickness. Since the titanium tubes 53 are distributed on the titanium cone surface, a gap 57 is formed between the outer side of the barrel and the composite wire 55. The function of the titanium tube 53 is to effectively separate the composite wire layer from the cone surface of the barrel. Then, the titanium barrel 5 wrapped with the composite wire 55 is placed in the electrolytic cell and falls on the titanium anode platform. The electrolyte is pumped in from the bottom of the electrolytic cell body 31 and enters the interior of the titanium barrel 5. It enters the gap 57 formed between the outer cone surface of the barrel and the composite wire 55 through the through hole on the cone surface of the barrel, and then evenly penetrates through the composite wire layer. In the process of the electrolyte passing through the composite wire layer, the chemical components in the electrolyte, such as nitric acid or sulfuric acid, react chemically with metal substances such as copper and iron in the composite wire 55. At the same time, the electrolyte Dissolution will also occur, dissolving the metals such as copper, iron and other substances that are not desired to be left in the composite wire 55 into the electrolyte, leaving the desired metal fibers such as stainless steel fibers. During the reaction process, the concentration of acid in the electrolyte will form a downward trend, and at the same time, the concentrations of copper ions and iron ions will slowly increase. At this time, the copper and iron removal capabilities of the electrolyte will decrease, which is not conducive to further efficient operation of the electrochemical process. Therefore, through the cooperation of the overflow port 313 and the liquid inlet 314, the electrolyte with poor activity is discharged from the overflow port 313 to the large circulating low-level solution pool 344. This part of the electrolyte with low acid content and high copper and iron ion content is fully stirred and ions are exchanged with the electrolyte in the large volume low-level pool. After dynamic acid addition, removal of copper and iron ions, the electrolyte components return to a new active state, and are then sent to the electrolytic cell through the liquid inlet pump 341 for chemical reaction, and circulated in sequence.

[0086] like Figures 2 to 11 As shown, a walking frame 1 includes a gantry 11, a walking mechanism installed at the bottom of the gantry 11 to drive the gantry 11 to move, a lifting mechanism 15 installed on the gantry 11, a drying mechanism 16 and a suction cup mechanism 18;

[0087] like Figure 7 、 8 As shown in Figures 9 and 10, the lifting mechanism 15 includes a lifting device, a fixed platform 152, a lifting platform 154 and a guide rod 153. In this embodiment, the lifting device adopts an electric hoist 151, the fixed platform 152 is installed on the top of the door frame 11, the lifting device is installed on the fixed platform 152, and the lifting platform 154 is arranged directly below the fixed platform 152. The lifting platform 154 is connected to the hook end of the lifting device, and four vertically arranged guide rods 153 are arranged in a rectangular shape and fixed on the door frame 11. The lifting platform 154 is provided with linear bearings at positions corresponding to the four guide rods 153. The lifting platform 154 is slidably installed on the four guide rods 153 through linear bearings. The lifting platform 154 is driven by the lifting device to move up and down along the guide rods 153; the four guide rods 153 are used to ensure that the lifting platform 154 is always accurately positioned on the central axis of the lifting platform 154 during the rising and falling process. Figure 10 As shown, the position of the lifting platform moving up and down is determined by the position sensor, which includes a first position sensor 155, a second position sensor 156 and a third position sensor 157. The first position sensor 155 is installed on the first mobile support beam 111, the second position sensor 156 is installed on the second mobile support beam 112, and the third position sensor 157 is installed on the door frame 11 and placed below the second mobile support beam. The first position sensor 155 is used to monitor whether the lifting platform reaches the position on the first mobile support beam. The first position sensor 155 controls the first mobile support beam. The support beam moves so that the lifting platform 154 can be accurately supported on the first movable support beam when in the walking state; the second position sensor 156 monitors whether the lifting platform has reached the position on the second movable support beam, and the second position sensor 156 controls the movement of the second movable support beam, so that the lifting platform 154 can be accurately supported on the second movable support beam when in the drying state; the third position sensor 157 is used to monitor the position of the lifting platform and control the opening and closing of the mechanical gripper 17, so as to accurately place the titanium barrel into the electrolytic cell body or the cleaning tank or accurately grab the titanium barrel from the electrolytic cell body or the cleaning tank;

[0088] like Figure 9 As shown, a drying mechanism 16 is installed below the lifting platform 154 , and a mechanical clamp 17 that matches the clamping ring 51 on the titanium barrel 5 is installed on the rotating end of the drying mechanism 16 .

[0089] In this embodiment, the drying mechanism 16 includes a second servo motor 161 and an electric cylinder 162. The mechanical clamp 17 adopts a floating self-centering chuck. The second servo motor 161 and the electric cylinder 162 are both vertically fixed on the lifting platform 154. The floating self-centering chuck is driven by the electric cylinder 162 to achieve the movement of the clamping claw 174, and the floating self-centering chuck is driven by the second servo motor 161 to achieve rotation.

[0090] Furthermore, the floating self-centering chuck includes a three-claw sliding chuck 173, which is rotatably assembled on the lifting platform 154. A driving gear 163 is coaxially mounted on the rotating shaft of the second servo motor 161, and a passive gear 164 matching the active gear 163 is coaxially mounted on the three-claw sliding chuck 173. The active gear 163 is meshed with the passive gear 164. The three-claw sliding chuck 173 includes a wedge core sleeve and at least three claws 174. The claws 174 are radially arranged and slidably mounted in the slide groove of the wedge core sleeve. A push-pull core rod 171 is coaxially fixed to the top of the wedge core sleeve, and the top of the push-pull core rod 171 abuts against the extended shaft of the electric cylinder 162 (in the initial state, there is a 1- 2mm gap), the push-pull core rod 171 is sheathed with a second compression spring 172, and the push-pull core rod 171 is returned to its original position after moving by the second compression spring 172. In this embodiment, three claws 174 are provided. The purpose is that during the spin-drying process, the weight of the rotating part includes the weight of the titanium barrel 5 itself, the metal fiber on the titanium barrel 5, the three-claw sliding chuck 173 and the passive gear 164, so the total weight is relatively large. In order to prevent the eccentricity of the center of gravity of the rotating part during spin-drying and generate additional centrifugal force, the weight of the chuck is more evenly distributed along the circumferential direction by providing three claws 174 to ensure the stability of the system during spin-drying. Of course, if four claws 174 or more claws 174 can also ensure stability, four claws 174 or more claws 174 can also be used.

[0091] During operation, the electric cylinder 162 pushes the push-pull core rod 171 to drive the wedge core sleeve to move axially. The wedge core sleeve converts the axial movement of the wedge core sleeve into radial movement of the claw 174, thereby achieving the clamping and loosening of the claw 174. Because the claw 174 matches the retaining ring 51 on the titanium barrel 5, the claw 174 is tightly attached to the inner wall of the retaining ring 51 when clamping. After clamping, the second servo motor 161 drives the meshing driving gear 163 to rotate at high speed, driving the three-claw sliding chuck 173 to rotate at high speed, thereby achieving the action of drying and dehydrating the fibers on the titanium barrel 5. Since the floating self-centering chuck belongs to the existing technology, its structure and principle will not be further described here.

[0092] like Figure 9 、 10 As shown, since the lifting platform 154 drives the titanium barrel 5 to realize two actions, namely, moving and drying, in order to ensure the stability of the lifting platform 154 during drying and walking, in this embodiment, a first movable support beam 111 and a second movable support beam 112 with the same structure are provided on the door frame 11, and the second movable support beam 112 is provided below the first movable support beam 111. When in the walking state, the lifting platform 154 is supported on the first movable support beam 111; when in the drying state, the lifting platform 154 is supported on the second movable support beam 112.

[0093] The first moving support beam 111 and the second moving support beam 112 both include a moving beam 113 and a beam driving mechanism 116 for driving the moving beam 113 to move horizontally. Horizontally arranged guide rails 115 are provided on the gantry 11 and on both sides of the lifting area of the lifting platform 154. The two moving beams 113 are respectively arranged on the left and right sides of the lifting area of the lifting platform 154, and the two ends of the moving beam 113 are slidably mounted on the top surface of the guide rails 115 through sliders 114. A rack is fixed on the bottom of the guide rails 115 along the direction of the guide rails 115. A beam driving mechanism 116 is installed at the bottom of the moving beam 113. The beam driving mechanism 116 includes a fourth servo motor and a second gear 183. The second gear 183 is mounted on the driving end of the fourth servo motor, and the second gear 183 is meshed with the rack. In this way, the moving beam can be driven by the action of the fourth servo motor. 113 moves on the guide rail 115; when the lifting platform 154 needs to be supported, the two moving beams 113 are driven relatively close to each other by the fourth servo motor to enter under the lifting platform 154, so that the lifting platform 154 falls on the moving beam 113, and the huge weight of the lifting platform 154 is no longer borne by the steel rope of the lifting equipment, but is transferred to the gantry 11 through the moving beam 113, thereby releasing the load of the steel rope of the lifting equipment; and in the drying state, it cooperates with the guide rod 153 to ensure that the huge centrifugal force generated by the rotation of the titanium barrel 5 during drying will not affect the stability of the lifting platform 154, so that the drying process proceeds smoothly; in the walking state, it also reduces the impact of the inertia of the lifting platform 154 on the four guide rods 153, greatly improving the stability of the system during operation; and when switching between the walking state and the drying state, the fourth servo motor drives the moving beam 113 to move accordingly.

[0094] like Figure 13As shown, the suction cup mechanism 18 includes an electromagnetic suction cup 181 and a linear drive mechanism, the linear drive mechanism is vertically mounted on the door frame 11, and an electromagnetic suction cup 181 matching the cover plate 32 is mounted on the driving end of the linear drive mechanism.

The horizontal transmission shaft 143 is rotatably assembled on the door frame 11, and the vertical transmission shaft 144 is rotatably assembled on the side of the door frame close to the front support leg. The horizontal transmission shaft 143 is driven to rotate by the first servo motor 141. The two ends of the horizontal transmission shaft 143 are respectively connected to the vertical transmission shaft 144 through a cone gear transmission box 142. A universal shaft 145 is installed at the bottom of the vertical transmission shaft 144. A first gear 146 is coaxially mounted on the universal shaft 145.

A spring pull rod mechanism is installed in the middle of the pre-tightening plate 121, and a sleeve 123 is slidably sleeved on the universal shaft 145. The pre-tightening plate 121 is connected to the sleeve 123 through the spring pull rod mechanism, thereby realizing the pre-tightening of the first gear 146 and the first rack 147; the spring pull rod mechanism includes a pull rod and a first compression spring 122, one end of the pull rod is connected to the sleeve 123, and the other end passes through the pre-tightening plate 121, on which the first compression spring 122 is sleeved, and one end of the first compression spring 122 is fixed on the pre-tightening plate 121 The other end is fixed on the pull rod, and the pull rod and the pre-tightening plate 121 are slidingly assembled; when working, since the upper end of the pre-tightening plate 121 is hinged to the crossbeam of the door frame 11 near the front support leg through a hinge, the pre-tightening plate 121 can rotate around the hinge, and a roller 124 is installed at the lower end of the pre-tightening plate 121. The roller 124 abuts against one side of the base 22 under the action of the first compression spring 122 of the spring pull rod mechanism.
