Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of weighing equipment, in particular to a steel plate automatic slicing and weighing equipment. BACKGROUND

[0002] Steel plate is a flat plate-shaped steel material made of molten steel after cooling and pressing. It is flat and rectangular, and can be directly rolled or cut from wide steel strips. After processing, the steel plate usually needs to be weighed to ensure that it meets the standards.

[0003] According to a Chinese patent with the publication number CN217171942U, a large plate weighing frame is disclosed. Through the work of the air cylinder, the weighing device and the bearing plate can be moved. The bearing plate can be moved to the bottom end of the plate. Through the work of the air cylinder, the bearing plate can drive the plate to move upwards, facilitating the weighing of the plate by the weighing device. When the weight of the top end of the bearing plate reaches a certain value, the first movable shaft, the first fixed plate, the first connecting strip, the second movable shaft and the second partition plate can move in the sliding slot through the sliding block. The connecting rod on one side of the second partition plate and the baffle can be moved out of the bottom end of the bearing plate, preventing the plate from falling due to shaking during weighing. However, the above device has good weighing effect for sliced plates, but cannot automatically weigh stacked plates after slicing. Therefore, the stacked plates need to be sliced in advance before being weighed one by one, which is very inconvenient to use. Therefore, we propose a steel plate automatic slicing and weighing equipment to solve the above technical problems. SUMMARY

[0027] As a preferred embodiment of the present invention, the torsion limiting unit includes:

[0028] The torsion plate is fixedly installed on the lower part of the outer wall of the rotating sleeve;

[0029] Two torsion limiting notches are formed on the outer wall of the torsion limiting disk, and the two torsion limiting notches are symmetrically distributed about the center of the torsion limiting disk.

[0030] The guide rod is slidably installed inside the tray via a linear bearing and extends through the bottom and top of the tray. There are four trays, which are arranged in a square shape about the center point of the tray.

[0031] Torque limiting blocks are fixedly installed on the top of the four guide rods;

[0032] A square slot is formed through the top of the torsion limiting block, and the square slot is located on the periphery of the rotating sleeve;

[0033] The clips are fixedly installed on the inner walls of the left and right sides of the square slot, and the clips are engaged inside the torque limiting notch.

[0034] The top plate is fixedly installed on the lower part of the outer wall of the four guide rods;

[0035] Rubber shock absorbers are fixedly installed at the bottom of the top plate.

[0036] In a preferred embodiment of the present invention, there are two sliding pins, which are symmetrically distributed about the center of the lifting rod; there are two spiral grooves, which correspond one-to-one with the positions of the two sliding pins; there are two torsion limiting grooves, which are symmetrically distributed about the center of the sleeve; and the inner walls of the two torsion limiting grooves are slidably connected to the outer walls of the two sliding pins.

[0037] As a preferred embodiment of the present invention, two deep groove bearings distributed vertically are fixedly installed on the upper part of the outer wall of the sleeve, and the rotating sleeve is rotatably installed with the outer wall of the sleeve through the two deep groove bearings.

[0038] As a preferred embodiment of the present invention, two linear guide rails distributed front and rear are fixedly installed on the top of the pallet, and two linear sliders distributed left and right are fixedly installed at the front end and rear end of the bottom of the movable seat. The position and specifications of the linear sliders correspond to the linear guide rails, and the linear sliders are slidably installed on the periphery of the corresponding linear guide rails.

[0039] As a preferred embodiment of the present invention, two springs are sleeved around the two guide rods, and the two springs are fixedly installed between the top of the top plate and the bottom of the support plate, with the two springs distributed diagonally about the top plate.

[0040] As a preferred embodiment of the present invention, two iron chains distributed on the left and right are fixedly installed on the top of the lifting frame, and a weighing instrument is fixedly connected to the top of the two iron chains. The top of the weighing instrument is connected to the winch end of an external lifting device via a hook.

[0041] Compared with the prior art, the beneficial effects of the present invention are:

[0042] 1. In this invention, the device is moved to the top of the stacked steel plates by an external lifting device as shown in the attached figure. Then, the hoisting section of the lifting device releases the device downward, so that the bottom of the electromagnet contacts the upper surface of the topmost steel plate. By generating a magnetic attraction effect on the electromagnet, the topmost steel plate is attracted. Then, the hoisting end of the lifting device drives the device to move upward, and lifts the topmost steel plate together with the others, separating them from the remaining steel plates. Afterward, the lifted single steel plate is weighed by a weighing instrument, thus achieving the automatic segmentation and weighing of the steel plates.

[0043] 2. In this invention, after the bottom of the electromagnet contacts the topmost steel plate, the lifting equipment lifts the device and the attracted steel plate upwards. During this process, the ends of the left and right distributed hooks contact the side edges of the bottom steel plate of the topmost steel plate. Therefore, the four hooks slide upwards along the side of the steel plate. Due to the contact between the side of the steel plate and the ends of the hooks, the left and right hooks cannot move towards the center. As the topmost steel plate is lifted, a gap is created between it and the bottom steel plate. At this time, under the action of gravity, the sleeve slides downwards along the outer wall of the lifting rod, and the two sliding pins are slidably connected to the two torsion-limiting grooves. Therefore, the lifting rod will not twist inside the sleeve. At the same time, the sleeve also drives the rotating sleeve to move downwards together. The two sliding pins slide along the inside of the two spiral grooves respectively, causing the rotating sleeve to twist at a certain angle along the outer wall of the sleeve, and driving the rotating plate and the two positioning pins to twist together. Furthermore, under the hinge action of the two connecting rods and the positioning pins, the two movable seats on the left and right move towards the middle. Both movable seats can move more stably and accurately through the sliding guidance of the linear slider and the linear guide rail. At the same time, the movement of the two movable seats on the left and right towards the middle drives the hooks distributed on the left and right to move towards the middle, hooking onto the bottom of the steel plate and supporting the bottom of the steel plate. In this way, the steel plate will not fall in the event of an emergency power failure of the electromagnet, improving the safety of the steel plate weighing.

[0044] 3. In this invention, before the electromagnet contacts the top surface of the top steel plate, the bottom of the rubber damping head first contacts the top surface of the steel plate. As the device continues to move downward, the contact between the bottom of the rubber damping head and the top surface of the steel plate pushes the top plate and the four guide rods upward along the inside of the support plate. At the same time, the four guide rods push the torsion limiting block and the locking head upward, causing the locking head to move upward along the inside of the torsion limiting notch, thus releasing the torsion limiting effect on the torsion limiting disc and the rotating sleeve. This way, the normal torsion of the rotating sleeve will not be interfered with during the lifting process, and the movement of the two left and right hooks towards the middle will not be affected, thereby supporting the steel plate. Furthermore, before the rubber damping head contacts the top surface of the steel plate, that is, before the locking head is engaged inside the torsion limiting notch, the rotating sleeve cannot be twisted, causing the two left and right hooks to not move, thus preventing the left and right hooks from moving towards the middle prematurely.

The electromagnet 400 is fixedly installed at the bottom of the steel structure frame 100 for picking up the steel plates.

[0058] For further details, please refer to [link / reference]. Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 As shown:

[0059] The support unit 200 includes a support plate 201, a movable seat 202, a hook 203, a sleeve 204, a deep groove bearing 205, a swivel sleeve 206, a lifting rod 207, a sliding pin 208, a spiral groove 209, a rotating plate 2010, a positioning pin 1 2011, a positioning pin 2 2012, a connecting rod 2013, a torsion limiting groove 2014, a lifting frame 2015, a spring 1 2016, a linear guide rail 2017, and a linear slider 2018. The support plate 201 is fixedly installed on the top of the steel structure frame 100. The movable seat 202 is movably positioned on the top of the support plate 201. The hooks 203 are fixedly installed on the front and rear ends of the top of the two movable seats 202, respectively, and the two hooks 203 in the left and right directions are symmetrically arranged. The sleeve 204 is fixedly installed on the steel structure frame 100. The frame 100 is topped and extends through the support plate 201 to its top periphery. A rotating sleeve 206 is rotatably mounted around the sleeve 204. A lifting rod 207 is slidably mounted inside the sleeve 204. A sliding pin 208 is fixedly mounted on the lower part of the outer wall of the lifting rod 207. A spiral groove 209 is formed on the inner wall of the rotating sleeve 206, and the rotating sleeve 206 is slidably mounted inside the spiral groove 209. A rotating plate 2010 is fixedly mounted on the outer wall of the rotating sleeve 206. A first positioning pin 2011 is fixedly mounted on the top left and right ends of the rotating plate 2010. A second positioning pin 2012 is fixedly mounted on the tops of the left and right movable seats 202 respectively. A connecting rod 2013 is hinged between the first positioning pin 2011 and the second positioning pin 2012 via a fisheye joint. A torsion limiting groove 2014 is formed through the sleeve. On the outer wall of sleeve 204, the outer wall of sliding pin 208 is slidably connected to the inner wall of torsion limiting groove 2014. Lifting bracket 2015 is fixedly installed on the upper part of the outer wall of lifting rod 207. Spring 2016 is fixedly installed between the bottom of lifting bracket 2015 and support plate 201, and is symmetrically distributed about the central axis of lifting bracket 2015. There are two sliding pins 208, symmetrically distributed about the center of lifting rod 207. There are two spiral grooves 209, their positions corresponding one-to-one with the positions of the two sliding pins 208. There are two torsion limiting grooves 2014, symmetrically distributed about the center of sleeve 204. The inner walls of the two torsion limiting grooves 2014 are slidably connected to the outer walls of the two sliding pins 208 respectively. The upper part of the outer wall of sleeve 204... Two vertically distributed deep groove bearings 205 are fixedly installed. The swivel sleeve 206 is rotatably installed on the outer wall of the sleeve 204 through the two deep groove bearings 205. Two linear guide rails 2017 distributed front and rear are fixedly installed on the top of the pallet 201. Two horizontally distributed linear sliders 2018 are fixedly installed at the front and rear ends of the bottom of the movable seat 202. The position and specifications of the linear sliders 2018 correspond to the linear guide rails 2017. The linear sliders 2018 are slidably installed on the periphery of the corresponding linear guide rails 2017. Two horizontally distributed iron chains 500 are fixedly installed on the top of the lifting frame 2015. The top of the two iron chains 500 is fixedly connected to the weighing instrument 600. The top of the weighing instrument 600 is connected to the winch end of the external lifting device through a hook.

[0060] Specifically, after connecting the top of the weighing instrument 600 to the winch end of the external lifting equipment, the equipment is moved to the top of the stacked steel plates using the external lifting equipment, as shown in the attached diagram. Figure 1 As shown, the hoisting equipment then releases the device downwards, causing the bottom of the electromagnet 400 to contact the upper surface of the topmost steel plate. The electromagnet 400 is magnetically attracted, holding the topmost steel plate in place. Subsequently, the hoisting equipment drives the device upwards, lifting the topmost steel plate and separating it from the other steel plates. Then, the weighing instrument 600 weighs the lifted steel plate, thus achieving automatic segmentation and weighing of the steel plates. This device is also equipped with safety measures to prevent the steel plate from falling in the event of an emergency power failure of the electromagnet 400. Specifically, when the bottom of the electromagnet 400 contacts the topmost steel plate, the device and the steel plate it holds are lifted upwards by the lifting equipment. During this process, the ends of the left and right distributed hooks 203 contact the side edges of the bottom steel plate of the topmost steel plate. Therefore, the four hooks 203 slide upwards along the side of the steel plate. Under the contact between the side of the steel plate and the ends of the hooks 203, the left and right hooks 203 cannot move towards the center. As the topmost steel plate is lifted, a gap is created between it and the bottom steel plate. At this time, under the action of gravity, the sleeve 204 slides downwards along the outer wall of the lifting rod 207, and the two sliding pins 208 are slidably connected to the two torsion limiting grooves 2014. Therefore, the lifting rod 207 will not twist inside the sleeve 204. As the sleeve 204 rotates, the rotating sleeve 206 moves downwards together. The two sliding pins 208 slide along the inside of the two spiral grooves 209 respectively, causing the rotating sleeve 206 to twist at a certain angle along the outer wall of the sleeve 204, and causing the rotating plate 2010 and the two positioning pins 2011 to twist together. Further, under the hinge action of the two connecting rods 2013 and the positioning pins 2012, the two movable seats 202 on the left and right move towards the middle. The two movable seats 202 can move more stably and accurately through the sliding guidance of the linear slider 2018 and the linear guide rail 2017. At the same time, the movement of the two movable seats 202 on the left and right towards the middle causes the hooks 203 distributed on the left and right to move towards the middle, hooking onto the bottom of the steel plate and supporting the bottom of the steel plate. In this way, the steel plate will not fall in the event of an emergency power failure of the electromagnet 400, improving the safety of the steel plate weighing.

[0061] It should be noted that the total elastic force of the two springs 2016 in this device is greater than the overall weight of the device but less than the total weight of the device and the steel plate. Therefore, before the device has gripped the steel plate, the sleeve 204 will not slide down the inner wall of the lifting rod 207 under the elastic force of the two springs 2016. In other words, the rotating sleeve 206 will not twist, and the left and right hooks 203 will not move towards the center, ensuring that the left and right hooks 203 can be placed on the side of the steel plate so that the electromagnet 400 can grip the steel plate. After the electromagnet 400 grips the steel plate, the total weight of the device plus the steel plate is greater than the elastic force of the two springs 2016. Therefore, during the lifting process, the sleeve 204 will slide down the outer wall of the lifting rod 207, causing the support plate 201 and the movable seat 202 to move downward together. The two springs 2016 are stretched and stored, eventually causing the left and right hooks 203 to move towards the center and hook onto the bottom of the steel plate, supporting the steel plate.

[0062] For further details, please refer to [link / reference]. Figure 5 , Figure 6 , Figure 7 , Figure 9 As shown:

[0063] The torsion limiting unit 300 includes a torsion limiting disc 301, a torsion limiting notch 302, a guide rod 303, a torsion limiting block 304, a square slot 305, a clamping head 306, a top plate 307, a rubber shock absorber head 308, and a second spring 309. The torsion limiting disc 301 is fixedly installed on the lower part of the outer wall of the rotating sleeve 206. Two torsion limiting notches 302 are formed on the outer wall of the torsion limiting disc 301, and the two torsion limiting notches 302 are symmetrically distributed about the center of the torsion limiting disc 301. The guide rod 303 is slidably installed inside the support plate 201 through a linear bearing and penetrates the bottom and top of the support plate 201. There are four support plates 201, and the four support plates 201 are distributed in a U-shape about the center point of the support plate 201. The torsion block 304 is fixedly installed on the top of the four guide rods 303. The square slot 305 is opened through the top of the torsion block 304. The square slot 305 is located on the periphery of the rotating sleeve 206. The clamping head 306 is fixedly installed on the inner wall of the left side and the inner wall of the square slot 305 respectively. The clamping head 306 is engaged in the inside of the torsion limiting notch 302. The top plate 307 is fixedly installed on the lower part of the outer wall of the four guide rods 303. The rubber shock absorber head 308 is fixedly installed on the bottom of the top plate 307. Two springs 309 are sleeved on the periphery of two guide rods 303. The springs 309 are fixedly installed between the top of the top plate 307 and the bottom of the support plate 201. The two springs 309 are distributed diagonally about the top plate 307.

[0064] Specifically, the hoisting equipment then releases the device downwards, causing the bottom of the electromagnet 400 to contact the upper surface of the topmost steel plate. It's important to note that before the electromagnet 400 contacts the uppermost steel plate, the bottom of the rubber damping head 308 first contacts the upper surface of that steel plate. As the device continues to move downwards, the contact between the bottom of the rubber damping head 308 and the upper surface of the steel plate pushes the top plate 307 and the four guide rods 303 upwards along the inside of the support plate 201. Simultaneously, the four guide rods 303 push the torsion limiting block 304 and the clamping head 306 upwards. The movement causes the locking head 306 to move upward along the inside of the torque limiting notch 302, releasing the torque limiting effect on the torque limiting disc 301 and the rotating sleeve 206. This ensures that the normal rotation of the rotating sleeve 206 will not be interfered with during the lifting process, and will not affect the movement of the two left and right hooks 203 towards the middle, thereby supporting the steel plate. Furthermore, before the rubber shock absorber head 308 contacts the upper surface of the steel plate, that is, before the locking head 306 is engaged inside the torque limiting notch 302, the rotating sleeve 206 cannot be rotated, causing the two left and right hooks 203 to not move, thus preventing the left and right hooks 203 from moving towards the middle prematurely.

[0065] This solution describes an automatic steel plate slicing and weighing device. During operation, the top of the weighing instrument 600 is connected to the winch end of an external lifting device. The external lifting device then moves the device to the top of the stacked steel plates, as shown in the attached diagram. Figure 1 As shown, the hoisting equipment then releases the device downwards, causing the bottom of the electromagnet 400 to contact the upper surface of the topmost steel plate. It is important to note that before the electromagnet 400 contacts the uppermost steel plate, the bottom of the rubber damping head 308 first contacts the upper surface of that steel plate. As the device continues to move downwards, the contact between the bottom of the rubber damping head 308 and the upper surface of the steel plate pushes the top plate 307 and the four guide rods 303 upwards along the inside of the support plate 201. Simultaneously, the four guide rods 303 pull the torsion limiting block 304 and the clamping head 3... 06 Push upwards to move the clamp 306 upwards along the inside of the torque limiting notch 302, releasing the torque limiting effect on the torque limiting disc 301 and the rotating sleeve 206 until the bottom of the electromagnet 400 contacts the upper surface of the topmost steel plate. The electromagnet 400 generates a magnetic attraction effect, attracting the topmost steel plate. Then, the hoisting end of the lifting equipment drives the equipment to move upwards, lifting the topmost steel plate together and separating it from the other steel plates. Afterwards, the weighing instrument 600 weighs the lifted single steel plate, thus achieving the automatic segmentation and weighing effect of the steel plate.

[0066] This device is also equipped with safety measures to prevent the steel plate from falling in the event of an emergency power failure of the electromagnet 400. Specifically, when the bottom of the electromagnet 400 contacts the topmost steel plate, the device and the steel plate it holds are lifted upwards by the lifting equipment. During this process, the ends of the left and right distributed hooks 203 contact the side edges of the bottom steel plate of the topmost steel plate. Therefore, the four hooks 203 slide upwards along the side of the steel plate. Under the contact between the side of the steel plate and the ends of the hooks 203, the left and right hooks 203 cannot move towards the center. As the topmost steel plate is lifted, a gap is created between it and the bottom steel plate. At this time, under the action of gravity, the sleeve 204 slides downwards along the outer wall of the lifting rod 207, and the two sliding pins 208 are slidably connected to the two torsion limiting grooves 2014. Therefore, the lifting rod 207 will not twist inside the sleeve 204. As the sleeve 204 rotates, it also drives the rotating sleeve 206 to move downwards together. The two sliding pins 208 slide along the inside of the two spiral grooves 209 respectively, causing the rotating sleeve 206 to twist along the outer wall of the sleeve 204 at a certain angle, and driving the rotating plate 2010 and the two positioning pins 2011 to twist together. Further, under the hinge action of the two connecting rods 2013 and the positioning pins 2012, the two movable seats 202 on the left and right move towards the middle. The two movable seats 202 can move more stably and accurately through the sliding guidance of the linear slider 2018 and the linear guide rail 2017. At the same time, the movement of the two movable seats 202 on the left and right towards the middle drives the hooks 203 distributed on the left and right to move towards the middle, hooking onto the bottom of the steel plate and supporting the bottom of the steel plate. In this way, the steel plate will not fall in the event of an emergency power failure of the electromagnet 400, improving the safety of the steel plate weighing.

[0067] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention.
