Description

Technical Field

[0001] This invention relates to the field of transportation and storage device technology, specifically to a production device for manufacturing refrigerated trucks. Background Technology

[0002] Refrigerated trucks require specialized refrigerated truck insulation panels during manufacturing. These panels typically use polyurethane (PU) or polystyrene (EPS) as the core material, with inner and outer composite panels made of fiberglass, color steel plates, etc., formed through integral foaming or composite molding. They possess high strength, low thermal conductivity, thermal insulation, waterproofing, and corrosion resistance, making them the core structural material of the refrigerated truck body. During production, warehousing, and transportation, refrigerated truck insulation panels need to be centrally stacked, arranged, and temporarily stored according to specifications and batches. The storage devices are generally refrigerated truck insulation panel stacking devices.

[0003] In existing technologies, refrigerated truck insulated box panel stacking devices generally lack automatic positioning, centering, and guiding mechanisms. They rely entirely on manual forklift operation for multi-layer stacking and retrieval of panels. Due to driver skill, blind spots, and forklift deviations, the depth and lateral position of each layer of panels exhibit significant random deviations, making consistent alignment impossible. Repeated manual adjustments and corrections are necessary, significantly increasing operation time and labor costs. Furthermore, while stacking devices may incorporate cushioning to prevent collisions when panels enter, the lack of cushioning, vibration damping, and securing capabilities prevents rigid collisions and impacts between the forklift arm and the stacking device body, and between the panels and the device frame, during high-frequency panel handling. This leads to continuous vibration of the entire stacking device, causing damage such as bumps, scratches, and deformation to other panels already stored on the frame. It also causes lateral or forward / backward displacement of the panels, resulting in misalignment, tilting, or even scattering of the originally neatly stacked panels, severely impacting storage stability and the smooth operation of subsequent retrieval, inspection, and processing. Summary of the Invention

[0004] (a) Technical problems to be solved: To address the shortcomings of existing technologies, this invention provides a production apparatus for manufacturing refrigerated truck molding, which solves the problems mentioned in the background art, such as inaccurate stacking and detection of refrigerated truck insulation box panels, large deviations in manual placement, and easy damage and displacement of panels due to collisions during storage and retrieval.

[0005] (II) Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: a production apparatus for manufacturing refrigerated truck molding, comprising: Several stacked storage units are provided with openings for entering and exiting the insulation box panels, for storing individual insulation box panels. The storage units include a base plate, an intermediate support bar perpendicular to the opening of the storage unit and fixedly connected to the top center of the base plate, two feeding mechanisms, and a fixed rotating plate. The top of the middle support bar, away from the storage unit, has a downward slope. A positioning backplate is fixedly connected to the side of the plurality of storage cells away from the opening; The feeding mechanism includes a pressing trigger and several toggle levers. The feeding mechanism uses the forklift arm to lower the pressing trigger, which in turn drives the toggle levers to rotate. The rotation of the toggle levers causes the end of the insulation box plate away from the forklift to tilt downwards along the slope. The fixed rotating plate has two ends. One end has a magnetic suction piece flush with the slope, and the other end has an insertion rod. The magnetic suction piece is attracted to the bottom of the inclined downward end of the insulation box material and moves as it returns to horizontal. The insertion rod is inserted into the positioning back plate during rotation, thus fixing the fixed rotating plate and the insulation box material.

[0006] Preferably, the storage unit further includes: Two side support bars are arranged on both sides of the central support bar and are symmetrical to the central support bar. The top of the two side support bars away from the storage unit is provided with a slope to assist the central support bar in jointly supporting the insulation box material stored in the storage unit.

[0007] Preferably, the slope has a receiving groove for accommodating the magnetic suction element that is pre-installed in the slope and flush with the slope.

[0008] Preferably, the positioning backplate is fixedly connected to the side near one of the storage units with: Elastic cushioning pads are designed to provide protection and cushioning for the insulation box panels upon contact.

[0009] Preferably, the dialing mechanism further includes: Several elastic reset components of the toggle part are fixedly connected at one end to the bottom of the pressing trigger component and at the other end to the base plate, and are used to provide a reset force for the pressing trigger component; The ratchet engages with the pressing trigger and is rotatably connected to the base plate, rotating under the influence of the downward-moving pressing trigger. The first transmission gear is fixedly connected to the ratchet and coaxial with it, and is rotatably connected to the base plate, away from the vertical plane where the pressing trigger is located; The second transmission gear meshes with the first transmission gear and is rotatably connected to the base plate; The third transmission gear meshes with the second transmission gear and is rotatably connected to the base plate; The turntable is rotatably connected to the base plate. A timing belt, one end of which is meshed with the third transmission gear and the other end of which is meshed with the feed turntable, is used to transmit the torque of the third transmission gear to the feed turntable, thereby driving the feed turntable to rotate away from the opening of the storage unit. A trigger push rod is fixedly connected to the dial and extends to the outside of the dial.

[0010] Preferably, the pressing trigger is slidably connected to the base plate, and its top is lower than the top of the intermediate support bar. The pressing trigger has a ratchet surface on the side near the ratchet, and the ratchet surface meshes with the ratchet. When the pressing trigger rises, the force of contacting the ratchet causes several elastic reset members of the actuating part to bend and deform. The ratchet surface does not mesh with the ratchet and does not cause the ratchet to rotate. The transmission ratios between the first transmission gear and the second transmission gear, between the second transmission gear and the third transmission gear, and between the third transmission gear and the turntable are all less than 1; When the pressing trigger descends to its lowest position, the dial rotates exactly one revolution; The tops of several of the toggle levers are made of rubber and are all fixedly connected to the outside of the dial, with the top of the lever located on the side of the dial near the opening of the storage unit being lower than the middle support bar. The ratchet, the first transmission gear, the second transmission gear, and the third transmission gear are all disposed in a cavity opened inside the base plate; Several of the aforementioned toggle levers and the timing belt are close to the intermediate support bar, while the pressing trigger is far from the intermediate support bar. The toggle levers and the timing belt are not in the same vertical plane and do not overlap.

[0011] Preferably, it further includes a testing organization, the testing organization comprising: A sliding base has two ends, is located inside the base plate and is slidably connected to the base plate; The driven wheel is located at one end of the sliding base near the dial and is rotatably connected to the sliding base. The trigger push rod contacts the driven wheel as the dial rotates, thereby driving the driven wheel and the sliding base to move towards the side closer to the opening of the storage unit. The controller is fixedly connected to the top of the sliding base at the end away from the driven wheel; A roughness detection head is fixedly connected to the top of the controller and is used to detect the roughness of the insulation box material. A cleaning brush is fixedly connected to the top of the sliding base at the end away from the driven wheel and located on the side of the controller away from the driven wheel. The top of the cleaning brush is higher than the top of the intermediate support bar. It is used to clean the surface of the insulation box material and avoid the stains attached to the surface of the insulation box material from interfering with the detection results of the roughness detection head. Several detection reset components are arranged parallel to the sliding base, with one end fixedly connected to the base plate and the other end fixedly connected to the side wall of the sliding base, for driving the sliding base to reset.

[0012] Preferably, the fixed rotating plate further includes: The main body of the rotating plate is slidably connected to the positioning back plate, with one end extending into the interior of the storage unit and the other end extending into the outside of the positioning back plate; The magnetic end base is fixedly connected to one end of the rotating plate body located inside the storage unit, and is fixedly connected to the bottom of the magnetic component to support the magnetic component.

[0013] Preferably, the insertion rod is fixedly connected to one end of the rotating plate body located outside the positioning back plate, forming an acute angle structure with the rotating plate body; The positioning back plate has a slot corresponding to the insertion rod on the side near the insertion rod, which is used to accommodate the insertion rod after rotation.

[0014] Preferably, it further includes: An encapsulation side plate is disposed on the outside of several storage units, and is used in conjunction with the positioning back plate to enclose several storage units except for the opening, thereby reducing the influence of the outside on the inside of the storage units. An alarm is fixedly connected to the top of the encapsulation side plate and is used to emit an alarm sound; The central control device is fixedly connected to the packaging side plate and electrically connected to the controllers of several storage units and the alarm, and is used to record the storage status of the insulation box material of each storage unit and control the alarm to work.

[0015] (III) Beneficial Effects: The production apparatus for manufacturing refrigerated trucks provided by this invention has the following beneficial effects: 1. This production device for refrigerated truck forming and manufacturing uses a feeding mechanism triggered by the downward pressure of a forklift arm, in conjunction with a support bar with a ramp and a positioning back plate with an elastic buffer pad. The feeding rod pushes the sheet material along the ramp and into contact with the elastic buffer pad to return it to its position, so that each layer of insulation box sheet material can be guided to the same aligned position without the need for repeated manual adjustment and correction. This solves the problem of large deviation in the position of sheet material placed by manual forklift operation in the prior art, which is time-consuming and labor-intensive, and realizes automatic centering and positioning of sheet material placement.

[0016] 2. The production device for manufacturing refrigerated truck molding uses a detection mechanism that links a cleaning brush with a roughness detection head. The cleaning brush first cleans the surface of the insulation box material to remove dust and oil, and then the roughness detection head completes the surface roughness detection of the material. This eliminates the interference of surface stains on the detection equipment from the source, thereby solving the problem of inaccurate material detection results caused by open storage environment in the prior art and ensuring the accuracy of the detection data.

[0017] 3. This production device for manufacturing refrigerated truck molding uses magnetic suction to attract the sheet metal and drive the fixed rotating plate to move, so that the insertion rod is inserted into the slot of the positioning back plate to form a self-locking mechanism, thus completing the stable fixation of the sheet metal. At the same time, the elastic buffer pad of the positioning back plate can absorb the impact force when the sheet metal comes into contact with the device, avoiding the vibration caused by the collision between the forklift and the device, which would cause the sheet metal of the insulated box to be bumped or displaced. This solves the problem of easy damage to the sheet metal and misplacement of stacking caused by collision during storage and retrieval in the prior art, and improves the stability of the insulated box sheet metal storage.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 refer to Figures 1 to 6 A production apparatus for manufacturing refrigerated trucks according to a preferred embodiment of the present invention will be described in detail below: Several stacked storage units are provided with openings for entering and exiting the insulation box panels, for storing individual insulation box panels, including a base plate 20, an intermediate support bar 21 perpendicular to the opening of the storage unit and fixedly connected to the top center of the base plate 20, two feeding mechanisms and a fixed rotating plate; The top of the middle support bar 21, which is away from the storage unit, has a downward slope 211. This slope provides guidance for the insulated box plate, which is tilted by the transfer mechanism after entering the storage unit. This allows the end of the insulated box plate away from the storage unit to move along the slope 211, avoiding jamming and damage caused by hard contact between the end of the insulated box plate and the end of the middle support bar 21. It also facilitates the tilting design of the magnetic suction component 511 for fixing the rotating plate and the rotation effect when the magnetic suction component 511 is attached to the bottom of the insulated box plate.

[0022] The positioning backplate 60 is fixedly connected to the side of several storage units away from the opening. It serves as the encapsulation plate on the back of all storage units, so that when the plate in each storage unit enters the storage unit and is moved by the tossing unit to contact the elastic buffer pad 61, it can be bounced to the same relative position. This avoids the problem of front-to-back position deviation when manually placing the insulation box plate in the prior art, and ensures that the multiple insulation box plates in the multi-layer storage unit are aligned.

[0023] The feeding mechanism includes a pressing trigger 30 and several toggle levers 361. The feeding mechanism uses the downward movement of the forklift arm to drive the pressing trigger 30 to descend. The downward movement of the forklift arm (which is also the placement movement of the insulation box material) serves as the triggering power for the feeding mechanism. No additional drive device is required. The toggle levers 361 rotate, and the rotation of the toggle levers 361 causes the end of the insulation box material away from the forklift to tilt downward along the ramp 211. The fixed rotating plate has two ends. One end has a magnetic suction piece 511 flush with the ramp 211, which ensures that the plate can quickly adhere to the bottom of the insulation box material when it moves along the ramp 211 (the outer skin of the insulation box material is metal with high hardness and is the bottom surface when stored, while the inner skin has no magnetic force). The magnetic force is used to fix the rotating plate to the insulation box material. The other end has a plug rod 52. The magnetic suction piece 511 is attracted to the bottom of the inclined end of the insulation box material and moves with it as it returns to horizontal. During the rotation, the plug rod 52 is inserted into the positioning back plate 60, which fixes the positioning back plate 60 to itself, thus fixing the rotating plate and the insulation box material.

[0024] The storage unit also includes: Two side support bars, arranged on both sides of the middle support bar 21 and symmetrical to the middle support bar 21, provide a multi-point support structure for the insulation box material, ensuring the stability of the insulation box material. The top of the two side support bars away from the storage unit has a ramp 211, which forms a uniform inclined guide surface with the middle support bar 21, and is used to assist the middle support bar 21 in supporting the insulation box material stored in the storage unit.

[0025] The ramp 211 has a receiving groove for accommodating the magnetic suction component 511 that is pre-placed in the ramp 211 and flush with the ramp 211. This prevents the magnetic suction component 511 from obstructing the movement of the insulation box material, ensuring the smooth sliding of the insulation box material along the ramp 211. It also reduces the distance between the magnetic suction component 511 and the insulation box material when placed, ensuring the rapid adsorption of the magnetic suction component 511 and the insulation box material.

[0026] The positioning backplate 60 is fixedly connected to the following on one side near several storage cells: The elastic buffer pad 61 is elastic to absorb the impact force when the insulated box material comes into contact with the elastic buffer pad 61 after being pushed by the conveying mechanism, so as to avoid scratches, dents and other damage caused by the contact between the insulated box material and hard materials, and to provide protection and cushioning for the insulated box material when in contact.

[0027] The calling agencies also include: Several elastic reset members 31 of the actuating part are fixedly connected at one end to the bottom of the pressing trigger member 30 and at the other end to the base plate 20, and are used to provide a reset force for the pressing trigger member 30. This allows the pressing trigger member 30 to quickly return to its initial position after it no longer contacts the forklift arm. Figure 5 As shown in the diagram, this prepares for the next forklift boom trigger action.

[0028] The ratchet 32 ​​is engaged with the pressing trigger 30 and rotatably connected to the base plate 20. It cooperates with the ratchet surface 301 to achieve unidirectional transmission. It only rotates when the pressing trigger 30 moves downward. When the pressing trigger 30 resets upward, it will not drive the ratchet 32 ​​to rotate in the opposite direction, thereby avoiding the pressing trigger 30 from driving the ratchet 32 ​​and subsequent components to work in the opposite direction when it resets.

[0029] The first transmission gear 321 is fixedly connected to the ratchet 32 ​​and coaxial with it, and is rotatably connected to the base plate 20. It rotates synchronously with the ratchet 32 ​​and is away from the vertical plane where the pressing trigger 30 is located, so as to avoid being on the same plane as the pressing trigger 30 and generating additional mutual contact when the forklift arm moves downward, which would affect the operation of the forklift arm.

[0030] The second transmission gear 33 meshes with the first transmission gear 321 and is rotatably connected to the base plate 20, and is used to transmit torque and change the direction of rotation.

[0031] The third transmission gear 34 meshes with the second transmission gear 33 and is rotatably connected to the base plate 20.

[0032] The turntable 36 is rotatably connected to the base plate 20 and moves as shown by the synchronous belt 35. Figure 5 The clockwise rotation of the angle causes the trigger push rod 37 to rotate clockwise in sync, which in turn moves the insulation box plate and tilts it.

[0033] Synchronous belt 35, one end of which meshes with third transmission gear 34, and the other end of which meshes with feed turntable 36, is used to transmit the torque of third transmission gear 34 to feed turntable 36, driving feed turntable 36 to rotate away from the opening of storage unit (as shown). Figure 5 (Clockwise rotation of the angle). Furthermore, the synchronous belt 35 has an accurate transmission ratio and smooth transmission, ensuring that the rotation angle of the dial 36 is approximately the same each time the feeding mechanism operates, guaranteeing consistent feeding results.

[0034] The trigger push rod 37 is fixedly connected to the dial 36 and extends to the outside of the dial 36. It rotates synchronously with the dial 36 and, while rotating with the dial 36, makes contact with the driven wheel 41 and pushes the detection mechanism without the need for additional electrical control components.

[0035] The pressing trigger 30 is slidably connected to the base plate 20, and its top is lower than the top of the intermediate support bar 21 to avoid affecting the insulation box material placed on the intermediate support bar 21. The pressing trigger 30 has a ratchet surface 301 on the side near the ratchet 32. The ratchet surface 301 is engaged with the ratchet 32. When the pressing trigger 30 rises, the force of contact with the ratchet 32 ​​causes several elastic reset parts 31 of the actuating part to bend and deform. The ratchet surface 301 does not engage with the ratchet 32 ​​and does not drive the ratchet 32 ​​to rotate, thus realizing unidirectional transmission with the ratchet 32.

[0036] The transmission ratios between the first transmission gear 321 and the second transmission gear 33, the second transmission gear 33 and the third transmission gear 34, and the third transmission gear 34 and the feed turntable 36 are all less than 1. Thus, the first transmission gear 321, the second transmission gear 33, the third transmission gear 34, and the feed turntable 36 work together to form a multi-stage gear speed increase, converting the small displacement distance of the pressing trigger 30, limited by the storage unit space, into a full rotation of the feed turntable 36.

[0037] When the trigger 30 is pressed down to its lowest position, the dial 36 rotates exactly one revolution, and the insulation resets. This achieves the desired agitation of the insulation box material while preventing damage to the insulation box material caused by excessive rotation of the lever 361.

[0038] Several actuating levers 361 have rubber tips, allowing them to deform when in contact with the insulation box material, preventing scratches. The deformation also increases the contact area and friction between the levers and the insulation box material, facilitating the movement of the insulation box material. All levers are fixedly connected to the outside of the conveying turntable 36, with the top of the levers located on the side of the turntable 36 closest to the storage unit opening lower than the central support bar 21, preventing the levers 361 from protruding from the central support bar 21 and interfering with the proper placement of the insulation box material. The ratchet 32, the first transmission gear 321, the second transmission gear 33, and the third transmission gear 34 are all located in the cavity inside the base plate 20, that is, hidden inside the base plate 20. This prevents external dust and debris from entering the gaps of these transmission structures and causing jamming. It also prevents forklift arms, insulated box plates, etc. from coming into contact with it and causing damage, thus extending its service life.

[0039] Several actuating levers 361 and timing belts 35 are close to the intermediate support bar 21, while the pressing trigger 30 is away from the intermediate support bar 21. The actuating levers 361 and timing belts 35 are not in the same vertical plane and do not overlap. Figure 2As shown, when the forklift arms enter the storage unit, to avoid the forklift arms from stably supporting the insulation box panels, the driver inserts the arms into the storage unit with the middle support bar 21 as the axis of symmetry. The two arms are close to the two side support bars on both sides. At this time, because several actuating levers 361 and synchronous belts 35 are close to the middle support bar 21, the arms do not contact these structures, but contact the pressing trigger 30 away from the middle support bar 21 and drive it down to trigger the dispatching mechanism. The principle is the same when the arms move out of the storage unit, and will not be described again here.

[0040] The encapsulation side plate 10 is set on the outside of several storage units and is used to cooperate with the positioning back plate 60 to seal several storage units except for the opening, preventing external dust, oil, water vapor and other impurities from entering the storage unit and avoiding them from adhering to the surface of the insulation box material and affecting subsequent testing and processing. At the same time, it reduces the corrosion of the material by external environmental factors and reduces the impact of external factors on the inside of the storage unit. Alarm 70 is fixedly connected to the top of the encapsulation side plate 10 and is used to emit an alarm sound; The central control device 80 is fixedly connected to the packaging side plate 10 and electrically connected to the controller 42 of several storage units and the alarm 70. It is used to record the storage status of the insulation box materials in each storage unit and control the alarm 70 to work. When the insulation box materials in the storage unit are placed backwards (determined by the testing agency by detecting the roughness of the bottom of the insulation box materials) or when the device is full, an alarm sound is triggered to promptly notify the operator to perform subsequent operations, replacing manual inspection and improving the intelligence and timeliness of the operation.

[0041] The following is the complete working process and working principle of the above embodiments: When the production equipment for manufacturing refrigerated trucks is in operation, the forklift arm inserts into the storage unit with the central support bar 21 as the axis of symmetry. The arm descends and contacts the storage unit, causing the pressing trigger 30 to move downward. The pressing trigger 30 drives the ratchet 32 ​​to rotate via the ratchet surface 301. Through multi-stage speed-increasing transmission via the first transmission gear 321, the second transmission gear 33, and the third transmission gear 34, the torque is then transmitted to the conveyor turntable 36 via the synchronous belt 35, causing the conveyor turntable 36 to complete a full rotation. The actuating lever 361 rotates accordingly and pushes the insulation box panel, causing the insulation box panel to tilt. The end away from the forklift tilts downward along the slope 211 of the central support bar 21 and the side support bar. The insulation box panel finally contacts the elastic buffer pad 61 on the positioning back plate 60, which cushions the impact and returns the panel to a uniform alignment position.

[0042] Example 2 refer to Figure 1 , Figure 2 , Figures 4 to 7 It also includes testing institutions, which include: The sliding base 40 has two ends, is located inside the base plate 20, and is slidably connected to the base plate 20. The sliding base 40 is the base of the entire testing mechanism, and the sliding connection with the base plate 20 ensures that the sliding base 40 moves horizontally and stably along the preset sliding track, ensuring the stable operation of the entire testing mechanism.

[0043] The driven wheel 41 is located at one end of the sliding base 40 near the feed turntable 36 and is rotatably connected to the sliding base 40. The trigger push rod 37, as it rotates with the feed turntable 36, contacts the driven wheel 41, causing the driven wheel 41 and the sliding base 40 to move towards the side closer to the storage unit opening. For example... Figure 7 As shown, the driven wheel 41 is rotatably connected to the sliding base 40, so that when the trigger push rod 37 contacts the driven wheel 41 and drives the entire detection mechanism to move, the rotation of the driven wheel 41 can reduce the friction when it contacts the trigger push rod 37, thus avoiding wear of the components caused by hard contact between the two.

[0044] The controller 42 is fixedly connected to the top of the sliding base 40 at the end away from the driven rotary wheel 41. It can receive the detection signal from the roughness detection head 421 and transmit the signal to the central control device 80. At the same time, it controls the working state of the roughness detection head 421. It is fixed on the sliding base 40 and can move with it.

[0045] The roughness detection head 421 is fixedly connected to the top of the controller 42 and is used to detect the roughness of the insulation box material. The outer skin of the insulation box material has high roughness and the inner skin has low roughness. The central control device 80 can determine whether the insulation box material placed in the storage unit is placed upside down by the roughness result detected by the roughness detection head 421, and use the alarm 70 to remind the personnel who placed it.

[0046] The cleaning brush 43 is fixedly connected to the top of the sliding base 40 at the end away from the driven wheel 41, and is located on the side of the controller 42 away from the driven wheel 41. When the sliding base 40 is moved by the rotating trigger push rod 37, the cleaning brush 43 cleans the area to be detected by the subsequent roughness detection head 421 in front of the roughness detection head 421, removing dust, oil, and other stains attached to it, eliminating the interference of stains on roughness detection from the source, and ensuring the accuracy of the detection results of the roughness detection head 421. The top of the cleaning brush 43 is higher than the top of the intermediate support bar 21, and is used to clean the surface of the insulation box material to avoid the stains attached to the surface of the insulation box material interfering with the detection results of the roughness detection head 421. Several detection reset components 44 are arranged parallel to the sliding base 40. One end is fixedly connected to the base plate 20, and the other end is fixedly connected to the side wall of the sliding base 40. After the trigger push rod 37 disengages from the driven wheel 41, it uses its own elasticity to drive the sliding base 40 to reset, preparing for the next detection work.

[0047] The following is the complete working process and working principle of the above embodiments: When the dispatching mechanism is working, the trigger push rod 37 rotates synchronously with the dispatching turntable 36. During its rotation, it comes into contact with the driven wheel 41 of the detection mechanism. Because the driven wheel 41 is rotatably connected to the sliding base 40, the frictional force during contact is effectively reduced, thereby driving the sliding base 40 to slide along the base plate 20 towards the side closer to the storage unit opening. During the movement of the sliding base 40, the insulation box plate is gradually lowered by the insert arm. The cleaning brush 43 on its top moves before the roughness detection head 421, cleaning the dust, oil, and other stains on the surface of the insulation box plate to eliminate the interference of stains on the detection. Subsequently, the roughness detection head 421 on the controller 42 performs roughness detection on the cleaned plate surface and transmits the detection signal to the central control device 80. The central control device 80 can determine whether the plate is placed in reverse based on the roughness difference between the outer and inner skin of the plate. When the dial 36 completes its rotation and the trigger push rod 37 disengages from the driven wheel 41, several detection unit reset components 44 rely on their own elasticity to drive the sliding base 40 to reset along the original trajectory, driving the cleaning brush 43, roughness detection head 421 and other detection mechanism components back to their initial positions, preparing for the next detection work.

[0048] Example 3 refer to Figures 8 to 10 The fixed rotating plate also includes: The rotating plate body 50 is slidably connected to the positioning back plate 60, so that the rotating plate body 50 can perform a combination of rotation and sliding along the groove opened in the positioning back plate 60. One end extends into the storage unit to provide an installation base for the magnetic suction component 511, and the other end extends to the outside of the positioning back plate 60 to provide an installation base for the insertion rod 52.

[0049] The magnetic base 51 is fixedly connected to one end of the rotating plate body 50 located in the storage unit and is fixedly connected to the bottom of the magnetic component 511 to support the magnetic component 511, so that the entire fixed rotating plate can be moved by the adsorption of the magnetic component 511 and the heat preservation box plate.

[0050] The insertion rod 52 is fixedly connected to one end of the rotating plate body 50 located outside the positioning back plate 60, forming an acute angle with the rotating plate body 50. For example... Figure 9 As shown in Figure 10, the acute angle formed by the rotating plate body 50 and the insertion rod 52 facilitates insertion into the slot 62 when the fixed rotating plate moves, ensuring self-locking after the insertion rod 52 is inserted into the slot 62, thus providing a certain degree of stability between the fixed rotating plate and the positioning back plate 60. When the insulation box material is lifted and removed by the insertion arm, the fixed rotating plate... Figure 9 Rotating clockwise at the indicated angle, the insert 52 disengages from the slot 62 and falls back to the position shown. Figure 2 The initial position is shown.

[0051] The positioning back plate 60 has a slot 62 corresponding to the insertion rod 52 on the side near the insertion rod 52, which is used to accommodate the insertion rod 52 after rotation.

[0052] The following is the complete working process and working principle of the above embodiments: After the forklift arm moves the insulated box material to the ground and triggers the conveying mechanism, the end of the insulated box material away from the forklift tilts downwards along the slope 211 of the middle support bar 21 and the side support bar. At this time, the magnetic suction component 511 of the fixed rotating plate is flush with the slope 211 and close to the bottom of the tilted end of the insulated box, so it can quickly adhere to the metal bottom surface of the tilted end of the insulated box material. As the insulated box material gradually returns to horizontal after the action of the conveying mechanism, the attraction force of the magnetic suction component 511 will drive the rotating plate body 50 to slide along the positioning back plate 60. The insertion rod 52 on the outside of the rotating plate body 50 will make compound movements with it and insert into the corresponding slot 62 opened in the positioning back plate 60 during the rotation. Since the insertion rod 52 and the rotating plate body 50 form an acute angle structure, they form a self-locking structure after insertion, so that the fixed rotating plate and the positioning back plate 60 are stably connected, thereby completing the fixation of the insulated box material and preventing it from shifting or bumping. When the forklift arm extends into the storage unit again to lift the insulated box panel, the lifting force of the insulated box panel will cause the magnetic suction component 511 to move upward synchronously, causing the rotating plate body 50 to rotate clockwise at the corresponding angle. The insertion rod 52 then disengages from the slot 62. After the fixed rotating plate loses its fixing force, it falls back to the initial position, releasing the fixing of the insulated box panel and making it easy for the insulated box panel to be removed smoothly.
