Description

Technical Field

[0001] The invention relates to a system for placing a hanging system on a shelf, and in particular to a system for automatically placing large-format materials on a shelf. Background Art

[0002] For some product manufacturers, it is usually necessary to apply a hanging system to realize the hanging and conveying of the constituent materials of the products so as to transport these materials to various workstations. For some large-format products, such as mattresses, sheets, quilt covers, bedding, etc., due to the large format of the materials, if workers manually clamp and put them on the shelves, the operation is laborious and the operation efficiency is not high. The large format mentioned is based on the size of ordinary clothing, which is larger than the format of this type of clothing. It is inconvenient for a single worker to clamp and hang them.

[0003] A driving device for an adjustable mattress is disclosed in a Chinese patent document (publication number: CN 207744922U), which relates to the technical field of mattresses. The present invention comprises a motor, a gear, a wheel shaft transmission device, a square shaft, a worm square shaft coupling, a worm, a worm wheel, a lead screw, a nut bracket and a push block. The output end of the motor is provided with a motor worm shaft, the gear is meshed with the motor worm shaft, the wheel shaft transmission device is coaxially connected with the gear, a square hole matching the square shaft is provided inside the wheel shaft transmission device, the two ends of the square shaft are respectively connected with the worm square shaft coupling, the worm is coaxially fixed with the worm square shaft coupling, the lead screw is arranged on both sides of the mattress and coaxially fixed with the worm wheel, the worm is meshed with the worm wheel, the nut bracket is matched with the lead screw thread, and the push block is connected with the nut bracket. The driving mechanism of an adjustable mattress of the present invention has more reliable self-locking, longer service life of the motor, more stable and reliable operation, and convenient disassembly and assembly, and is convenient for debugging and maintenance.

[0004] The structure of this driving device is relatively complex. When driving the mattress, it is easy to produce stubborn wrinkles on the surface fabric of the mattress, which cannot well meet the driving requirements of the mattress. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an automatic shelving system for large-format materials, which can well adapt to the automatic shelving of large-format materials and has little damage to the surface of the materials.

[0006] A technical solution to solve the technical problem: an automatic racking system for large-format materials, used to clamp large-format materials to a hanger in a hanging system, the structure includes a workbench, the materials used are used to be spread flat on the workbench surface, a bracket and a rack are provided at the position of the workbench, the bracket and the rack are both extended into the upper side of the workbench, the rack is arranged close to the hanging system, the hanger has a plate-type clamping structure, and is characterized in that it also includes: The opening and closing device is arranged on the frame and located on the upper side of the workbench, and comprises a pushing mechanism fixedly connected to the frame, a pushing member connected to the pushing mechanism, and a plug-in structure connected to the pushing member. Driven by the pushing mechanism, the plug-in structure is used to act on the position of the plate clamp ear plate on the hanger to realize the opening of the plate clamp; The driving mechanism is arranged on the bracket, located on the upper side of the workbench, and is connected to the driving motor; it includes a driving wheel, and a driving belt is connected to the driving wheel. The driving belt is formed with a straight portion with a certain length at the bottom of the driving mechanism. The straight portion drives the material to move horizontally on the workbench toward the opening and closing device in a manner of conflicting with the surface of the material, so as to realize the clamping of the material by the plate clamp.

[0007] The hanger is used in a hanging system as a carrier of the hanging system to realize hanging and conveying of materials, semi-finished products or finished products in a clamping manner. Corresponding to such large-format materials, the clamping structure on the hanger generally includes a clamping plate that is approximately fan-shaped, and the clamping plate is arranged in an elastic hinged manner. When the driving device drives the material, the straight portion on the driving belt mainly drives the material in a static frictional manner, so that the material moves horizontally toward the opening and closing device on the workbench. Under the action of the pushing mechanism, the plug-in structure abuts against the ear plate position, and the plate clamp can rotate and open to form a clamp. After the material enters the clamp, the pushing mechanism retracts, and the plate clamp reverses to close the clamp. The plate clamp abuts against the fabric to realize clamping of the fabric. When clamping materials, the hanger is still connected to the hanging system. The position of the hanger can be limited by setting a limit structure on the workbench or the frame; or the hanger can be manually placed in the correct position so that the plug-in structure on the pusher can accurately contact the ear plate on the plate clamp.

[0008] Furthermore, the driving mechanism further comprises a semi-enclosed shell, the driving wheel and the transmission belt are both arranged in the shell, the lower side of the shell is open, and the straight portion is located at the opening and protrudes downward. By providing the shell, a mounting base is provided for other structures in the driving mechanism, the structure of the driving mechanism is compact, and when the driving mechanism is working, other structures will not affect the material.

[0009] Furthermore, a plurality of feed wheels are provided on one side of the driving wheel in the housing, and the wheel axles of these feed wheels are bridged on the opposite side walls of the housing; among these feed wheels, the position of the outermost feed wheel is higher than the position of the inner feed wheel, and the drive belt is connected to these feed wheels, and the drive belt protrudes to the outside of the housing at the position of the feed wheel, so that a feed port is formed at the position of the feed wheel. By providing the feed wheel, on the one hand, it is convenient to form a relatively large feed port to facilitate the interaction between the material and the drive belt; on the other hand, the inner feed wheel provides support for the drive belt, so that the drive belt can interact stably with the surface of the material. If the feed port is used as the discharge end of the material, it can also be adapted to the full drive of the drive belt to the material. By providing a passive wheel in the housing, it is convenient to form the relatively large straight portion, so that the material can be stably driven. Of course, the straight portion can also be formed between the driving wheel and the feed wheel, or between the passive wheel and the feed wheel.

[0010] Furthermore, one driving motor corresponds to two sets of driving mechanisms arranged in parallel in the horizontal direction, and the rotating shaft connected to the driving motor is bridged on the two sets of driving mechanisms. The driving wheels in the two sets of driving mechanisms are fixedly connected to the two ends of the rotating shaft, and the two sets of driving mechanisms are supported by the rotating shaft. Through the structural setting of the double driving belt, the material can be driven stably. Moreover, the two sets of driving mechanisms are supported by the rotating shaft, and the driving mechanism has a certain degree of freedom of movement, which can adapt well to the surface of the material, so that the driving belt and the material can be stably contacted. It is also possible to provide appropriate support for the entire driving mechanism by setting a tension spring between the shell and the bracket to prevent the driving mechanism from excessive movement on the rotating shaft.

[0011] Furthermore, the driving motor is connected to the outer end of the cantilever, the inner end of the cantilever is hinged on the bracket, and a power mechanism is provided between the bracket and the cantilever, which causes the outer end of the cantilever to rise and fall. Through the arrangement of the cantilever, the lifting and lowering of the driving mechanism can be effectively realized, and the driving requirements for materials of different thicknesses can be better adapted.

[0012] Furthermore, the driving mechanism includes a transverse driving mechanism and a longitudinal driving mechanism, and the movement directions of the driving belts in the longitudinal driving mechanism and the transverse driving mechanism are perpendicular. The longitudinal driving mechanism is used to realize the advancement of the material, and the transverse driving mechanism is used to adjust the position of the material in the width direction of the workbench so that the clamping position of the hanger to the material is reasonable.

[0013] Furthermore, the pusher includes a movable frame, the movable frame includes two side plates arranged in parallel, the movable frame is pivotally connected to a fixed block, the fixed block is connected to the push mechanism, and the plug-in structure is bridged on the two side plates. The pusher has a simple structure and can stably contact with the plate clamp on the hanger, which is convenient for applying force. The fixed block can effectively realize the transmission connection between the pusher and the push mechanism.

[0014] Furthermore, the plug-in structure is a plug-in rod, one end of which is rotatably connected to one side plate, and the other end of which elastically contacts the other side plate. The rod-type plug-in rod can be well adapted to the structure of the ear plate on the plate clamp, which is conducive to the stable force application on the plate clamp. The connection method between the plug-in rod and the two side plates also makes it easy for the plug-in rod to be disengaged from the ear plate on the plate clamp.

[0015] Furthermore, the push mechanism is provided with a slide rail, which is arranged along the movement direction of the pusher, and a slider is slidably arranged on the slide rail, one end of the connecting piece is fixedly connected to the slider, and the other end is connected to the fixed block. Through the arrangement of the slide rail and the connecting piece, the pusher has good movement position accuracy under the drive of the push mechanism, which helps to stabilize the cooperation between the plug rod and the plate clamp.

[0016] Furthermore, a positioning piece is provided on the slider, the positioning piece extends toward the lower side of the pushing mechanism, the lower end of the positioning piece is bent, and a positioning opening is provided on the bent portion of the lower end of the positioning piece. By providing the positioning piece, relative positioning is performed with the corresponding structure on the hanging system through the positioning opening on the positioning piece, thereby facilitating the installation of the pushing mechanism to an accurate position, so that after the pushing mechanism drives the pushing member to move, the plug-in structure on the pushing member can accurately extend into the position of the ear plate on the plate clamp, thereby improving the working stability of the opening and closing device.

[0017] Compared with the prior art, the present invention has the following beneficial effects: the driving device is used to drive large-format materials, and when hanging large-format materials on a rack, manual work is reduced, and the device can well adapt to hanging large-format materials on a rack, and the operation efficiency is high. By forming a straight portion with a certain size on the driving belt, the straight portion conflicts with the surface of the material, and on the basis of meeting the driving requirements for large-format materials, the straight portion on the driving belt causes little damage to the surface of the material, and the surface of the material is well protected.

[0018] The opening and closing device can make the plate clamp on the hanger rotate and open to form a clamping opening. After the material is translated onto the workbench and enters the clamping opening, the opening and closing device retracts the plate clamp to reset the material, thereby achieving the clamping of the material and completing the automatic shelving of the material. In the process of clamping the material, less manpower is involved, which can effectively reduce the manpower cost and improve work efficiency. Through the plug-in structure and the ear plate position of the plate clamp on the hanger, the action position is reasonable, which can well adapt to the force applied to the plate clamp, so that the plate clamp can rotate smoothly.

DETAILED DESCRIPTION

[0029] In conjunction with the drawings in the specification, the automatic loading system for large-format materials is used to clamp large-format materials to the hanger in the hanging system. The hanger will carry the materials on the hanging system to transport them so as to complete subsequent processing procedures for the materials.

[0030] A plurality of hangers need to be provided on the hanging system, and the hangers involved are provided with a plate-type clamping structure, that is, Fig. 9The main structure of the plate-type clamping structure is similar to the hanger structure shown in FIG. 2 . The plate-type clamping structure includes a plate clamp 22 that is approximately fan-shaped. The plate clamp 22 is hinged on the frame 21 of the hanger. The plate clamp 22 abuts against the frame 21 under the action of the elastic member, thereby forming the plate-type clamping structure. In the figure, an ear plate 221 extending upward is integrally formed at the upper corner of the plate clamp 22. When manually operating, the plate clamp 22 is rotated to open the plate-type clamping structure by pressing the ear plate 221 with a finger. After releasing the finger, the plate clamp 22 rotates under the action of the elastic member to close the plate-type clamping structure, thereby clamping the material entering the plate-type clamping structure.

[0031] The structure of the racking system includes a workbench 1, which has a work plane, and the material is horizontally spread on the work plane. A bracket 2 is provided at the position of the workbench 1. The bracket 2 shown in the figure is supported by the ground, and the upper end of the bracket 2 extends into the upper side of the workbench 1. The bracket 2 can also be a suspension bracket, which is supported by the roof of the factory building, and the lower end of the suspension bracket extends into the upper side of the workbench 1. A driving device for driving the material to move horizontally on the workbench is provided on the bracket 2, and the driving device includes a driving mechanism 3 arranged on the bracket 2, and the driving mechanism 3 is located on the upper side of the workbench 1. The driving mechanism 3 is connected to the driving motor 36 in a transmission manner, and the driving motor 36 provides power for the operation of the driving mechanism 3. The driving mechanism 3 includes a driving wheel 38, and the driving motor 36 is connected to the driving wheel 38 in a transmission manner. Under the power of the driving motor 36, the driving wheel 38 rotates, and the driving wheel 38 is connected to the driving belt 32. After the driving wheel 38 rotates, it moves with the driving belt 32. The driving belt 32 is formed with a straight portion 321 of a certain length at the bottom of the driving mechanism 3. The length of the straight portion 321 is measured in centimeters, generally about ten to twenty centimeters long, which can be determined according to the characteristics of the material to be driven. When driving the material, the straight portion 321 conflicts with the upper surface of the material. When the straight portion 321 moves under the drive of the driving wheel 38, it can drive the material to move horizontally on the workbench 1 toward the direction of the hanger in the hanging system. At this time, the clamping structure on the hanger is in an open state, and generally the edge of the material directly enters the clamping structure. After the clamping structure is closed, the clamping of the hanger to the material is completed.

[0032] For compactness of structure, the driving mechanism 3 further comprises a semi-enclosed housing 31, which is approximately triangular in shape. The driving wheel 38 and the transmission belt are both arranged in the housing 31, the lower side of the housing 31 is open, and the straight portion 321 is located at the opening, and the straight portion 321 of the driving belt 32 protrudes downward to the outside of the housing 31, so that the straight portion 321 can stably contact the surface of the material.

[0033] A plurality of feed wheels 30 are arranged on one side of the driving wheel 38 in the housing 31. The figure shows three feed wheels 30. The axles of the three feed wheels 30 are arranged side by side. The axles of the feed wheels 30 are bridged on the opposite side walls of the housing 31. Among the feed wheels 30, the position of the outermost feed wheel 30 is higher than that of the inner feed wheels 30. The drive belt 32 is connected to the feed wheels 30. The drive belt 32 protrudes to the outside of the housing 31 at the position of the feed wheel 30. Due to the limitation of the setting position of the outermost feed wheel 30, a feed port is formed at the position of the feed wheel 30. The feed port is larger outside and smaller inside from the workbench 1, so that the material can smoothly enter the gap between the drive belt 32 and the workbench 1, which is well adapted to the drive requirements of the material. A driven wheel 37 is provided on the other side of the driving wheel 38 in the housing 31, and the axle of the driven wheel 37 is bridged on the opposite side walls of the housing 31. The driving belt 32 is connected to the driven wheel 37, and the straight portion 321 is formed between the driven wheel 37 and the feed wheel 30. In order to facilitate the tensioning of the driving belt 32, a tensioning wheel 39 is also provided in the housing 31, and the axle of the tensioning wheel 39 is also bridged on the opposite side walls of the housing 31. The driving wheel 38, the driven wheel 37, and the feed wheel 30 are located on the inner side of the driving belt 32, and the tensioning wheel 39 is located on the outer side of the driving belt 32, and the outer peripheral surface of the tensioning wheel 39 presses against the outer surface of the driving belt 32. The driving wheel 38, the driven wheel 37, the feed wheel 30, and the tensioning wheel 39 are arranged in the housing 31, so that the driving belt 32 is arranged in a curved shape in the housing 31. Figure 3 As shown in the figure, the wheel axles of the wheel structures include a column tube 7, the two ends of which are respectively in contact with the inner wall surfaces of the opposite side walls of the shell 31, so that the installation space width inside the shell 31 is maintained, and screws passing through the corresponding side walls of the shell 31 are respectively threadedly connected at the two ends of the column tube 7, thereby achieving stable support of the side walls of the shell 31 by the column tube 7, and facilitating the installation and disassembly of the shell 31.

[0034] One driving motor 36 corresponds to two sets of driving mechanisms 3. The two sets of driving mechanisms 3 are arranged side by side in the horizontal direction. The straight parts 321 of the driving belts 32 in the two sets of driving mechanisms 3 are parallel. The rotating shaft 34 connected to the driving motor 36 is bridged on the two sets of driving mechanisms 3, that is, the two ends of the rotating shaft 34 extend into the corresponding housing 31 respectively, and the driving wheels 38 in the two sets of driving mechanisms 3 are fixedly connected to the two ends of the rotating shaft 34. The side wall of the housing 31 is generally fixedly connected with a hollow support seat and a bearing. The rotating shaft 34 can rotatably pass through the bearing, and the housing 31 is supported on the rotating shaft 34 through the support seat and the bearing. Of course, the two sets of driving mechanisms 3 can also be directly supported on the rotating shaft 34 through the driving belt 32 and the driving wheel 38. In order to adapt to this structure, a tension spring 6 is provided between the bracket 2 and the housing 31. The two ends of the tension spring 6 are connected to the housing 31 and the bracket 2 respectively. The tension spring 6 is in a stretched state. In the actual working process, the stretching degree of the tension spring 6 generally changes.

[0035] The driving motor 36 is fixedly connected to the outer end of the cantilever 33, and a hinge column 4 is fixed to the inner end of the cantilever 33. A hinge ring 5 is fixedly connected to the corresponding position of the bracket 2. The hinge column 4 is rotatably inserted in the hinge ring 5, so that the inner end of the cantilever 33 is hinged to the bracket 2. A power mechanism is provided between the bracket 2 and the cantilever 33, and the power mechanism causes the outer end of the cantilever 33 to rise and fall. The power mechanism shown in the figure is a power cylinder 35, the cylinder body of the power cylinder 35 is movably connected to the bracket 2, and the piston rod in the power cylinder 35 is movably connected to the cantilever 33. Under the action of the power cylinder 35, the outer end of the cantilever 33 can rise and fall. Of course, the power mechanism can also be a screw mechanism.

[0036] The driving mechanism 3 includes a transverse driving mechanism 23 and a longitudinal driving mechanism 13, and the movement directions of the driving belts 32 in the longitudinal driving mechanism 13 and the transverse driving mechanism 23 are perpendicular. There are two groups of longitudinal driving mechanisms 13 and one group of transverse driving mechanisms 23. The two groups of longitudinal driving mechanisms 13 are arranged in a straight line, and the movement directions of the driving belts 32 on the two groups of longitudinal driving mechanisms 13 are the same. The longitudinal driving mechanism 13 is used to drive the material to move in the length direction of the workbench 1 to realize the movement of the material toward the hanger. It is also possible that the longitudinal driving mechanism 13 on the upstream side adjusts the longitudinal position of the material on the workbench 1 so that the material can smoothly enter the longitudinal driving mechanism 13 at the downstream position to be driven forward by the longitudinal driving mechanism 13 on the downstream side. The transverse driving mechanism 23 is used to drive the material to move in the width direction of the workbench 1 so that the material is in the middle position in the width direction of the workbench 1. Normally, the transverse drive mechanism 23 is first started to adjust the position of the material on the workbench 1. Of course, the operation of the transverse drive mechanism 23 is not necessary for production, and it will only be started when the material position needs to be adjusted.

[0037] When operating, a worker is usually required to stand next to the workbench 1 to control the corresponding drive mechanism 3. The control buttons of the corresponding drive mechanism 3 can be integrated into a controller, and the worker can control it according to the actual working conditions. It can be determined whether the transverse drive mechanism 23 needs to be started according to the position of the material on the workbench 1. The drive belt 32 in the transverse drive mechanism 23 can have two opposite directions of movement. In the actual operation process, there is no precise requirement for the position of the material in the width direction of the workbench 1. This is mainly determined by the worker based on actual experience. For materials of different thicknesses, the interval between the drive mechanism 3 and the workbench 1 can be adjusted by a power mechanism, or when the drive belt 32 is entangled with the surface of the material, the drive mechanism 3 can be disengaged from the surface of the material by a power mechanism. After the material is leveled, the drive mechanism 3 can be lowered to drive the material normally.

[0038] In order to realize the automatic shelving of materials, an opening and closing device is provided near the position of the hanging system to act on the plate clamp 22 on the hanger, so that the plate clamp 22 deflects and forms a clamp. The material is pushed by the driving device and moves toward the opening and closing device on the workbench 1. The material will enter the clamp. After the opening and closing device releases the action on the plate clamp 22, the plate clamp 22 is reset to achieve the clamping of the material. When the opening and closing device acts on the plate clamping structure on the hanger, the hanging part at the upper end of the hanger is hung on the plate drive chain in the hanging system. In order to ensure the accuracy of the action position, a position sensor 11 is provided on the outside of the opening and closing device. The position sensor 11 is used to sense the conveying position of the plate drive chain to the hanger. After the hanger is conveyed to the position, the plate drive chain stops moving, the hanger is in place, and then the opening and closing device is started to apply force to the plate clamp 22. After the plate clamp 22 has finished clamping the material, the worker can operate the control switch to start the plate drive chain, and the hanger with the material clamped will be transported to the ring rail of the hanging system by the plate drive chain for subsequent processing of the material.

[0039] A frame 9 is provided at the position of the workbench 1, and the frame 9 shown in the figure is supported by the ground in the factory. The frame 9 extends into the upper side of the workbench 1, and is closer to the hanging system than the aforementioned bracket 2. The frame 9 can also be connected to the aforementioned bracket as a whole, so that the overall firmness is good. The structure of the opening and closing device includes a pushing mechanism, which is fixed to the upper end of the frame 93, and the pushing mechanism is on the upper side of the workbench 1. The mounting frame 10 can be built by some hollow profiles and a number of connecting parts, and the mounting frame 10 is fixed to the upper end of the frame 9. The mounting frame 10 realizes the connection between the pushing mechanism and the frame 9, so that the pushing mechanism is in a suitable spatial position. The installation position of the opening and closing device can be determined according to actual needs, but in order to quickly and accurately install the opening and closing device, a positioning piece 13 is provided on the slider 15, and the positioning piece 13 extends toward the lower side of the pushing mechanism, and the lower end of the positioning piece 13 is bent, and a positioning port is provided on the bent portion of the lower end of the positioning piece 13.

[0040] After the plate drive chain delivers the empty hanger to the position, the lower end of the hanger rests on the workbench 1. The position of the lower end of the hanger on the workbench 1 can be adjusted manually by a worker, or by setting some position adjustment mechanisms on the surface of the workbench 1 to adjust the position of the lower end of the hanger so that the opening and closing device can accurately match the force-bearing part of the hanger. A protruding positioning structure can also be set on the workbench 1 to match the hanger, such as Figure 5 A protruding curved plate 8 is provided at one end of the workbench 1. The hanger can be deformed to a certain extent so that the hanger can be buckled on the curved plate 8 to achieve left and right positioning of the hanger on the workbench 1. Under the push of the aforementioned driving device, the edge of the material will move upward along the curved surface of the curved plate 8, and in this process, the edge of the material will enter the clamping opening of the plate clamp 22.

[0041] The pushing mechanism shown in the figure is a pushing cylinder 12, which is arranged in an inclined manner. The pushing cylinder 12 can also be replaced by a screw mechanism, but the preferred pushing mechanism is the pushing cylinder 12. The pushing member is movably connected to the outer end of the piston rod of the pushing cylinder 12. Driven by the pushing cylinder 12, the pushing member moves linearly. A plug-in structure is connected to the pushing member. Driven by the pushing mechanism, the plug-in structure moves toward the hanger at the accurate position. When the plate clamp 22 is acted on, the plug-in structure is inserted into the gap between the ear plate 221 and the hanger frame 21. Under the action of the pushing cylinder 12, the plug-in structure can stably apply force to the plate clamp 22, so that the upper end of the plate clamp 22 is deflected outward. The material spread on the workbench 1 is driven by the driving device and can smoothly enter the gap between the plate clamp 22 and the frame 21. After the piston rod in the pushing cylinder 12 is retracted, the clamping of the material can be completed.

[0042] The pusher includes a movable frame 18, which includes two parallel side plates 182. Two limit rods 181 are bridged between the two side plates 182, and the two limit rods 181 are arranged in parallel and spaced apart. A guide wheel 16 is connected to the front end of the push cylinder 12 through a connecting frame. The guide wheel 16 corresponds to the position of one of the side plates 182. When the piston rod in the push cylinder 12 retracts, the side plate 182 touches the outer peripheral surface of the guide wheel 16, so that the movable frame 18 is stabilized at the outer end of the piston rod. A fixed block 19 is fixedly connected to the outer end of the piston rod of the push cylinder 12, and the fixed block 19 is located in the interval between the two limit rods 181. The movable frame 18 is pivoted to the fixed block 19. A torsion spring is provided at the pivot position of the movable frame 18, and the torsion spring acts on the movable frame 18, so that the movable frame 18 has a certain stability on the fixed block 19. The plug-in structure is arranged on the movable frame 18, and the plug-in structure is a plug-in rod 20, and the plug-in rod 20 is movably bridged on the movable frame 18. When the pusher of this structure acts on the plate clamp 22, it can stably wrap around the ear plate 221 of the plate clamp 22, so that the plate clamp 22 can be stably applied with force. The plug-in rod 20 is L-shaped, and a fixed sleeve 202 is fixedly connected to one side of the movable frame 18. One end of the plug-in rod 20 is inserted into the fixed sleeve 202 with a gap. The spring 201 is sleeved on the plug-in rod 20 and acts on the plug-in rod 20. The spring 201 causes the other end of the plug-in rod 20 to contact the corresponding side plate 182 of the movable frame 18. A notch is provided on the corresponding side plate 182, and the other end of the plug-in rod 20 is used to contact the notch, so that the plug-in rod 20 can be accurately positioned on the movable frame 18, so that when the plate clamp 22 acts, the plug-in rod 20 can be accurately in place.
