Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, and specifically to an intelligent welding device with a fixed-point cleaning function. Background Art

[0002] A grille plate, also known as a steel grating or steel grid plate, is a steel product made by arranging flat steel in a certain spacing and crossbars and welding them into a steel product with square grids in the middle by a pressure welder or manually. Its crossbars usually adopt twisted square steel, with a firm structure and high load-bearing capacity.

[0003] The current welding devices have the following main problems when welding grille plates: (1) The welding slag and waste gas are not treated, resulting in environmental pollution; (2) The surface of the grille plate before welding is not cleaned, resulting in poor welding. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent welding device with a fixed-point cleaning function to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An intelligent welding device with a fixed-point cleaning function, including a frame. Feed lines are respectively arranged at both ends of the frame. Plates are arranged on both groups of feed lines. A support frame is arranged above the frame. A fixed cylinder is arranged on the support frame. A driving motor is installed on the fixed cylinder. A sliding plate is installed inside the fixed cylinder. Two adsorption covers are arranged on the lower side of the sliding plate. A laser is installed between the two adsorption covers. A detection cover is installed on one side of the fixed cylinder. Thermal imagers are installed on both sides of the detection cover. A conveyor belt is installed inside the detection cover. A positive plate and a negative plate are installed on the conveyor belt.

[0006] The inside of the fixed cylinder is hollow. The output end of the driving motor is connected to a lead screw. The two ends of the lead screw are rotatably installed inside the fixed cylinder. A sliding groove is arranged on the inner wall of the fixed cylinder. The sliding plate is slidably connected to the fixed cylinder through the sliding groove. The middle of the sliding plate is threadedly connected to the lead screw.

[0007] Two tympanic cylinders are respectively connected between the two ends of the sliding plate and the fixed cylinder. Both groups of tympanic cylinders are cylindrical. Both groups of tympanic cylinders are made of elastic materials. A number of folds are arranged on both groups of tympanic cylinders. An activated carbon plate is arranged on the inner wall of the left tympanic cylinder. The activated carbon plate is a soft plate. A first chamber is formed between the inside of the left tympanic cylinder, the sliding plate and the fixed cylinder. A second chamber is formed between the inside of the right tympanic cylinder, the sliding plate and the fixed cylinder.

[0008] When the exhaust gas enters the left eardrum tube, the left eardrum tube is stretched to the right by the sliding plate. At this time, the folds on the left eardrum tube gradually unfold, and the contact area between the activated carbon plate in the left eardrum tube and the exhaust gas increases, and the exhaust gas treatment effect will be enhanced simultaneously.

[0009] A plurality of jet holes are arranged on the lower side of the tympanic membrane tube on the right side, and the plurality of jet holes are directly opposite to the positions where two groups of plates need to be welded. A one-way valve is installed in the plurality of jet holes. An air intake pipe is arranged on one side of the tympanic membrane tube on both sides, and the air intake pipe is connected to the external atmosphere. A solenoid valve is installed in the air intake pipe, and the solenoid valve is electrically connected to the control system.

[0010] The adsorption hood is hollow inside, and two groups of first rollers are installed inside the adsorption hood. A screen is commonly sleeved on the outside of the two groups of first rollers. An electromagnetic plate is arranged on the screen, and the electromagnetic plate is electrically connected to the control system. The inside of the screen passes through the adsorption hood through a pipeline and is connected to the tympanic membrane tube on the left side. A switch valve is installed in the pipeline connecting the screen and the tympanic membrane tube on the left side, and the switch valve is electrically connected to the control system.

[0011] A high-temperature plate is arranged on the adsorption cover located inside the screen, a low-temperature plate is arranged outside the adsorption cover, a scraper is arranged on the adsorption cover directly above the screen, the scraper is in contact with the electromagnetic plate, and a slag discharge port is opened on the adsorption cover, and the slag discharge port is located on the upper side of the screen.

[0012] When the multiple electromagnetic plates facing the welding position work for a set time, the multiple electromagnetic plates facing the welding position will absorb a large amount of welding slag, and these electromagnetic plates need to be cleaned. At this time, the control system drives the multiple electromagnetic plates facing the welding position to move through the first roller, so that the electromagnetic plates that absorb welding slag move to the upper side of the adsorption cover, and the electromagnetic plates that do not absorb welding slag move to the lower side of the adsorption cover and face the welding position;

[0013] When the electromagnetic plate that absorbs welding slag moves close to the scraper, multiple electromagnetic plates need to be powered off in turn to facilitate the cleaning of welding slag in turn. While multiple electromagnetic plates are moving, the scraper scrapes off the welding slag on the electromagnetic plates at the same time. The scraped welding slag is located on the upper side of the adsorption cover, and the staff takes out the welding slag through the slag discharge port at the same time.

[0014] The upper end of the detection cover is connected to a telescopic rod of a telescopic electric cylinder, and the telescopic electric cylinder is installed on a support frame. The interior of the detection cover is hollow, and two groups of second rollers are installed inside the detection cover. The conveyor belt is sleeved on the two groups of second rollers. The positive plate and the negative plate are sequentially installed on one side of the conveyor belt, and the positive plate and the negative plate are respectively connected to the positive pole and the negative pole of the power supply through a wire, and a plurality of refrigeration plates are arranged on the other side of the conveyor belt.

[0015] A vertical shaft is arranged on the sliding plate between the two adsorption covers. A sliding cylinder is slidably mounted on the vertical shaft. A telescopic spring is connected between the vertical shaft and the sliding cylinder. The telescopic spring is sleeved on the vertical shaft. The laser is installed on the sliding cylinder. Both ends of the telescopic spring and the laser are electrically connected to the control system.

[0016] The two thermal imagers are installed on the detection cover. The thermal imagers are electrically connected to the control system.

[0017] Two different materials of semiconductors and metal plates are arranged on the high-temperature plate, the low-temperature plate and the refrigeration plate. One ends of the two different semiconductors are both connected to the metal plate. The two semiconductors on the high-temperature plate and the two semiconductors on the low-temperature plate are connected by wires. One of the wires is connected to the control system. The two semiconductors on the refrigeration plate are connected to the control system by wires.

[0018] The two feeding lines are each composed of a number of third rollers. The number of third rollers are all installed on the frame. The plates on both sides are respectively in contact with the third rollers on both sides. Encoders and pressure sensors are built in the first roller, the second roller, the third roller, the drive motor and the telescopic electric cylinder.

[0019] A control panel is arranged on the frame. The control system is arranged inside the control panel.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. Recycle the heat of the welding slag to reduce the energy consumption of the welding device. The technical solution provided by this application enables the heat generated during the welding process to be recycled through the Seebeck effect when welding the grating plate, and the generated current is processed and used for cooling the refrigeration plate to reduce the energy consumption of the welding device.

[0022] 2. Adsorb and treat the welding slag and waste gas to avoid environmental pollution. The control system energizes the electromagnetic plate. The energized electromagnetic plate generates a magnetic field, enabling the electromagnetic plate to attract the welding slag generated during the welding process. The sliding plate simultaneously pulls the left tympanic cylinder and squeezes the right tympanic cylinder. The folds on the left tympanic cylinder pulled by the sliding plate gradually unfold, increasing the volume of the first chamber in the tympanic cylinder. At this time, the welding slag generated during the welding process enters through the adsorption cover. The welding slag is attracted by the electromagnetic plate on the screen and deposited on the electromagnetic plate. The waste gas generated during the welding process passes through the screen and the pipeline and enters the left tympanic cylinder. The activated carbon plate in the left tympanic cylinder adsorbs the waste gas generated by the welding to prevent smoke from polluting the environment.

[0023] 3. Before welding the grid plate, perform a cleaning treatment to improve the welding yield. The volume of the second chamber in the right eardrum cylinder gradually decreases, and the air pressure in the second chamber gradually increases. The pressurized air pushes open the one-way valve in the air injection hole, causing the pressurized air to be ejected through the air injection hole at the positions where the two groups of plates need to be welded, so as to clean the positions to be welded, prevent external dust from having an adverse effect on the welding positions, and improve the welding yield.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment: As Figures 1 - 11 shown, the present invention provides a technical solution of an intelligent welding device with a fixed-point cleaning function, including a frame 11. Feeding lines are respectively arranged at both ends of the frame 11. Plates 12 are arranged on both groups of feeding lines. A support frame 111 is arranged above the frame 11. A fixed cylinder 13 is arranged on the support frame 111. A driving motor 2 is installed on the fixed cylinder 13. A sliding plate 21 is installed in the fixed cylinder 13. Two adsorption hoods 22 are arranged on the lower side of the sliding plate 21. A laser 23 is installed between the two adsorption hoods 22. A detection hood 3 is installed on one side of the fixed cylinder 13. Thermal imagers 31 are installed on both sides of the detection hood 3. The two thermal imagers 31 are installed on the detection hood 3. The thermal imager 31 is electrically connected to the control system. A conveyor belt 32 is installed in the detection hood 3. A positive plate 33 and a negative plate 34 are installed on the conveyor belt 32. Both groups of feeding lines are composed of a plurality of third rollers 14. The plurality of third rollers 14 are all installed on the frame 11. The plates 12 on both sides are respectively in contact with the third rollers 14 on both sides. A control panel 1 is arranged on the frame 11. A control system is arranged in the control panel 1.

[0038] The inside of the fixed cylinder 13 is hollow. The output end of the drive motor 2 is connected to a lead screw 201. Both ends of the lead screw 201 are rotatably installed in the fixed cylinder 13. A sliding groove is provided on the inner wall of the fixed cylinder 13. The sliding plate 21 is slidably connected to the fixed cylinder 13 through the sliding groove. The middle of the sliding plate 21 is threadedly connected to the lead screw 201. Two groups of tympanic membrane cylinders 211 are respectively connected between both ends of the sliding plate 21 and the fixed cylinder 13. Both groups of tympanic membrane cylinders 211 are cylindrical. Both groups of tympanic membrane cylinders 211 are made of elastic materials. A number of folds are provided on both groups of tympanic membrane cylinders 211. An activated carbon plate (not shown in the figure) is provided on the inner wall of the left tympanic membrane cylinder 211. The activated carbon plate is a soft plate. A first chamber is formed between the inside of the left tympanic membrane cylinder 211, the sliding plate 21 and the fixed cylinder 13. A second chamber is formed between the inside of the right tympanic membrane cylinder 211, the sliding plate 21 and the fixed cylinder 13.

[0039] When waste gas enters the left tympanic membrane cylinder 211, since the left tympanic membrane cylinder 211 is driven by the sliding plate 21 to be stretched to the right, at this time, the folds on the left tympanic membrane cylinder 211 are gradually unfolded, and the contact area between the activated carbon plate in the left tympanic membrane cylinder 211 and the waste gas increases, and the treatment effect of the waste gas will be enhanced synchronously.

[0040] A number of air injection holes 212 are provided on the lower side of the right tympanic membrane cylinder 211. The number of air injection holes 212 are opposite to the positions where the two groups of plates 12 need to be welded. One-way valves are installed in the number of air injection holes 212. Air inlet pipes 213 are provided on one side of both tympanic membrane cylinders 211. The air inlet pipes 213 are communicated with the external atmosphere. Solenoid valves are installed in the air inlet pipes 213. The solenoid valves are electrically connected to the control system.

[0041] The adsorption hood 22 is hollow inside. Two groups of first rollers 221 are installed inside the adsorption hood 22. A screen 222 is sleeved outside the two groups of first rollers 221. An electromagnetic plate 224 is arranged on the screen 222. The electromagnetic plate 224 is electrically connected to the control system. The inside of the screen 222 is connected to the left tympanic cylinder 211 through a pipe after passing through the adsorption hood 22. A switching valve is installed in the pipe connecting the screen 222 and the left tympanic cylinder 211. The switching valve is electrically connected to the control system; A high-temperature plate 223 is arranged on the adsorption hood 22 inside the screen 222. A low-temperature plate 226 is arranged outside the adsorption hood 22. A scraper 225 is arranged on the adsorption hood 22 directly opposite above the screen 222. The scraper 225 contacts the electromagnetic plate 224. A slag discharge port is opened on the adsorption hood 22. The slag discharge port is located above the screen 222; A vertical shaft 231 is arranged on the sliding plate 21 between the two adsorption hoods 22. A sliding cylinder is slidably installed on the vertical shaft 231. A telescopic spring 232 is connected between the vertical shaft 231 and the sliding cylinder. The telescopic spring 232 is sleeved on the vertical shaft 231. The laser 23 is installed on the sliding cylinder. Both ends of the telescopic spring 232 and the laser 23 are electrically connected to the control system. Encoders and pressure sensors are built into the first roller 221, the second roller 321, the third roller 14, the drive motor 2, and the telescopic electric cylinder 301.

[0042] When multiple electromagnetic plates 224 facing the welding position work for a set time, the multiple electromagnetic plates 224 facing the welding position will adsorb a large amount of welding slag, and the electromagnetic plates 224 in this part need to be cleaned. At this time, the control system drives the multiple electromagnetic plates 224 facing the welding position to move through the first roller 221, so that the electromagnetic plates 224 adsorbing welding slag move to the upper side of the adsorption hood 22, and the electromagnetic plates 224 not adsorbing welding slag move to the lower side of the adsorption hood 22 and face the welding position.

[0043] When the electromagnetic plates 224 adsorbing welding slag move close to the scraper 225, the multiple electromagnetic plates 224 need to be powered off in sequence to facilitate the cleaning of welding slag in sequence. While the multiple electromagnetic plates 224 are moving, the scraper 225 simultaneously scrapes the welding slag on the electromagnetic plates 224. The scraped welding slag is located above the adsorption hood 22, and the staff simultaneously takes out the welding slag through the slag discharge port.

[0044] The upper end of the detection hood 3 is connected to the telescopic rod of the telescopic electric cylinder 301. The telescopic electric cylinder 301 is installed on the support frame 111. The detection hood 3 is hollow inside. Two groups of second rollers 321 are installed inside the detection hood 3. The conveyor belt 32 is sleeved on the two groups of second rollers 321. The positive electrode plate 33 and the negative electrode plate 34 are sequentially installed on one side of the conveyor belt 32. The positive electrode plate 33 and the negative electrode plate 34 are respectively connected to the positive pole and the negative pole of the power supply through wires. A plurality of refrigeration plates 35 are arranged on the other side of the conveyor belt 32.

[0045] Two different materials of semiconductors and metal plates are provided on the high-temperature plate 223, the low-temperature plate 226, and the refrigeration plate 35. One end of the two different semiconductors is connected to the metal plate. The two semiconductors on the high-temperature plate 223 and the two semiconductors on the low-temperature plate 226 are connected by wires, and one of the wires is connected to the control system. The two semiconductors on the refrigeration plate 35 are connected to the control system by wires.

[0046] Working principle: Press the start button on the control panel 1, and the welding device starts. The control system first energizes the telescopic spring 232. Each turn of the telescopic spring 232 generates a magnetic field that attracts each other. This magnetic field causes the overall shortening of the telescopic spring 232. The telescopic spring 232 pulls the sliding cylinder to slide upward on the vertical shaft 231, and the sliding cylinder drives the laser 23 to move upward, so that the laser 23 does not contact the plate 12, facilitating subsequent cleaning of the plate 12.

[0047] The staff conveys the two groups of plates 12 through the third rollers 14 on both sides respectively. The third roller 14 on the left drives the plate 12 on the left to move to the right, and the third roller 14 on the right drives the plate 12 on the right to move to the left, so that the positions of the two sides of the plates 12 that need to be welded are located directly below the laser 23.

[0048] When the positions of the two sides of the plates 12 that need to be welded are located directly below the laser 23, the encoders inside the third rollers 14 on both sides feed back the displacement data of the two sides of the plates 12 to the control system. The control system opens the solenoid valve in the left air inlet pipe 213 (the air inlet pipe 213 connected to the left tympanic cylinder 211), and drives the screw rod 201 to rotate through the drive motor 2. The screw rod 201 drives the sliding plate 21 to slide to the right. The sliding plate 21 squeezes the right tympanic cylinder 211 and stretches the left tympanic cylinder 211.

[0049] When the sliding plate 21 moves to the right and squeezes the right tympanic cylinder 211, since the solenoid valve in the right air inlet pipe 213 (the air inlet pipe 213 connected to the right tympanic cylinder 211) is in the closed state, the gas in the right tympanic cylinder 211 cannot be discharged through the right air inlet pipe 213. As the sliding plate 21 gradually squeezes the right tympanic cylinder 211, the folds on the right tympanic cylinder 211 gradually contract, and the tympanic cylinder 211 changes from the original unfolded state to the folded state. At this time, the volume of the second chamber in the right tympanic cylinder 211 gradually becomes smaller, and the air pressure in the second chamber gradually becomes larger. The pressurized air pushes open the one-way valve in the air injection hole 212, so that the pressurized air is sprayed on the positions of the two groups of plates 12 that need to be welded through the air injection hole 212 to clean the positions that need to be welded, preventing external dust from having an adverse impact on the welding position. Since there are several air injection holes 212, fixed-point cleaning of the welding position can be achieved.

[0050] After the sliding plate 21 moves to the far right, the encoder in the driving motor 2 feeds back the displacement data of the sliding plate 21 to the control system. The control system controls the driving motor 2 to reverse and opens the solenoid valve in the right air inlet pipe 213 (the air inlet pipe 213 connected to the right tympanic cylinder 211). The driving motor 2 drives the lead screw 201 to reverse, and the lead screw 201 drives the sliding plate 21 to move left. The sliding plate 21 stretches the right tympanic cylinder 211 and squeezes the left tympanic cylinder 211. External air enters the right tympanic cylinder 211 through the right air inlet pipe 213 to achieve air replenishment, facilitating the use of air for cleaning next time;

[0051] When the sliding plate 21 moves to the far left, the encoder in the driving motor 2 feeds back the displacement data of the sliding plate 21 to the control system. The control system closes the solenoid valve in the right air inlet pipe 213 to prevent gas leakage.

[0052] By continuously rotating the driving motor 2 forward and backward, external air enters the right tympanic cylinder 211 through the right air inlet pipe 213. After the air is pressurized, it is sprayed at the positions where the two groups of plates 12 need to be welded for cleaning. During this process, the air inlet pipe 213 connected to the left tympanic cylinder 211 is in the open state. After the external gas enters the left tympanic cylinder 211 through the left air inlet pipe 213, it is discharged from the left air inlet pipe 213. Therefore, the left tympanic cylinder 211 is in a non-working state.

[0053] When the two groups of plates 12 are cleaned by pressurized air, the encoder in the driving motor 2 feeds back the displacement data of the sliding plate 21 to the control system. The control system cuts off the power supply to the telescopic spring 232. After the telescopic spring 232 is powered off, it gradually elongates under its own elastic force. The telescopic spring 232 pushes the sliding cylinder to move downward on the vertical shaft 231, and the sliding cylinder drives the laser 23 to move downward, so that the laser 23 contacts the positions where the two groups of plates 12 need to be welded, facilitating the welding process.

[0054] When the power supply to the telescopic spring 232 is cut off for the set time, the control system opens the switching valve in the pipeline connecting the sieve 222 and the left tympanic cylinder 211, closes the left air inlet pipe 213, and opens the right air inlet pipe 213. The driving motor 2 drives the lead screw 201 to rotate forward, and the lead screw 201 drives the sliding plate 21 to move right. While the sliding plate 21 drives the laser 23 to move right, the laser 23 laser-welds the two groups of plates 12;

[0055] When the laser 23 welds two groups of plates 12, the control system energizes the electromagnetic plate 224. The energized electromagnetic plate 224 generates a magnetic field, enabling the electromagnetic plate 224 to attract the welding slag generated during the welding process. The sliding plate 21 simultaneously pulls the left tympanic membrane cylinder 211 and squeezes the right tympanic membrane cylinder 211. The wrinkles on the left tympanic membrane cylinder 211 pulled by the sliding plate 21 gradually unfold, causing the volume of the first chamber in the tympanic membrane cylinder 211 to gradually increase. At this time, the welding slag generated during the welding process enters through the adsorption hood 22. The welding slag is attracted by the electromagnetic plate 224 on the screen 222 and deposits on the electromagnetic plate 224. The waste gas generated during the welding process passes through the screen 222 and the pipeline and enters the left tympanic membrane cylinder 211. The activated carbon plate in the left tympanic membrane cylinder 211 adsorbs the waste gas generated by the welding to prevent smoke from polluting the environment. Since the intake pipe 213 on the right tympanic membrane cylinder 211 is in an open state, at this time, the air in the right tympanic membrane cylinder 211 is discharged to the atmosphere through the right intake pipe 213. At this time, the right tympanic membrane cylinder 211 is in a non-working state.

[0056] After the welding slag enters the adsorption hood 22, the high-temperature welding slag approaches the high-temperature plate 223, while the low-temperature plate 226 is located outside the adsorption hood 22 and is in contact with the atmosphere. The two semiconductors and the metal plate on the high-temperature plate 223 are the hot ends of the Seebeck effect, and the two semiconductors and the metal plate on the low-temperature plate 226 are the cold ends of the Seebeck effect. The temperature of the hot end is higher than that of the cold end. A current is generated between the hot end and the cold end through the Seebeck effect and is transmitted to the control system. After the control system processes this current, it is used to cool the cooling plate 35.

[0057] When the laser 23 finishes welding two groups of plates 12, at this time, the laser 23 is located on the far right. At this time, the control system energizes the telescopic spring 232, and the telescopic spring 232 pulls the laser 23 upward, so that the laser 23 does not contact the two groups of welded plates 12.

[0058] After the laser 23 stops contacting the two groups of plates 12, at this time, the telescopic spring 232 will be energized for a set time. After that, the control system closes the switching valve in the pipeline connecting the screen 222 and the left tympanic membrane cylinder 211 and opens the solenoid valve in the left intake pipe 213. The control system drives the lead screw 201 to reverse through the drive motor 2. The lead screw 201 drives the sliding plate 21 to move to the left. The sliding plate 21 drives the laser 23 and the adsorption hood 22 to move to the left. At this time, the laser 23 does not contact the two groups of plates 12 and is in a non-working state. The sliding plate 21 simultaneously squeezes the left tympanic membrane cylinder 211 and stretches the right tympanic membrane cylinder 211. Since the intake pipe 213 on the right tympanic membrane cylinder 211 is in an open state, at this time, external air enters the right tympanic membrane cylinder 211 through the right intake pipe 213. At this time, the right tympanic membrane cylinder 211 is in a non-working state.

[0059] After welding is completed, when the sliding plate 21 presses against the left tympanic membrane cylinder 211, the volume of the first chamber in the left tympanic membrane cylinder 211 gradually decreases. The air that has been treated by the activated carbon plate in the first chamber is discharged from the left air inlet pipe 213 into the external air. Since the waste gas generated by welding is adsorbed by the activated carbon plate, the gas discharged from the left air inlet pipe 213 will not pollute the environment.

[0060] When the welded sliding plate 21 moves to the leftmost position, the two third rollers 14 on both sides cooperate to drive the two groups of welded plates 12 to move to the right, so that the welding positions of the two groups of plates 12 are directly opposite the thermal imager 31. The quality of the welding is detected by the thermal imager 31, and the detection data is fed back to the control system.

[0061] When the two groups of welded plates 12 move below the thermal imager 31, the control system drives the detection cover 3 to move downward through the telescopic electric cylinder 301. The detection cover 3 drives the two groups of second rollers 321 and the conveyor belt 32 to move downward, so that the positive plate 33 and the negative plate 34 on the conveyor belt 32 are in contact with the welding position. After that, the control system connects the positive plate 33 and the negative plate 34 to the positive and negative poles of the power supply respectively, so that current flows through the welding position. The control system calculates the resistance of the welding position through Ohm's law, and then obtains the welding quality of the welding position, and cooperates with the thermal imager 31 to judge whether the welding quality meets the requirements; if the welding quality is unqualified, the buzzer in the control panel 1 will alarm to remind the staff, and the defective data will be fed back on the control panel 1; if the welding quality is qualified, the buzzer will not alarm.

[0062] After the welding position is detected, the telescopic electric cylinder 301 drives the two groups of second rollers 321, the positive plate 33, the negative plate 34 and the conveyor belt 32 to move upward through the detection cover 3, and drives the conveyor belt 32 to move through the second roller 321. The conveyor belt 32 drives the refrigeration plate 35 to be directly opposite the welding position.
