Description

Technical Field

[0001] The present invention relates to the technical field of storage goods transportation, and specifically relates to a storage goods transportation device. Background Art

[0002] With the development of the domestic economy, especially the rapid progress of production enterprises, more and more production requires the sorting and transportation of a large number of stored goods. There are many and diverse goods to be shipped out every day. The transportation device is particularly important for production enterprises that produce fragile items. The movement of the goods on the transportation device can effectively avoid the product breakage caused by bumps during the handling process.

[0003] Considering that the equipment may need to stop during operation, since the existing transmission unit is usually directly connected to the drive motor, when the drive motor loses power, it will stop instantly, and at the same time, the transmission unit will stop. When transporting items, the items may fall due to inertia. When the transported items are fragile items, the fragile items may fall and break, resulting in property losses; at the same time, in case of power outage or tripping, the items will also fall. Summary of the Invention

[0004] The purpose of the present invention is to provide a storage goods transportation device to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is a storage goods transportation device, including a transmission unit. The transmission unit includes a transmission belt. Both sides of the transmission belt are fixedly connected with baffles. A plurality of rotating shafts are meshed on the inner surface of the transmission belt; the rotating shafts all penetrate through the baffles and are rotatably connected with the baffles; one side of the baffle is fixedly connected with an isolation cover, and the bottom of the baffle and the isolation cover is fixedly connected with a bracket; the bracket is used to support the device; one side of the transmission belt is a feed inlet, and the other side is a discharge outlet; The rotating shaft near the feed inlet is a drive shaft, and the drive shaft is fixedly connected with a drive unit; the rotating shaft adjacent to the drive shaft is a slow-stop shaft, and the slow-stop shaft is slidably connected with a slow-stop unit; the rotating shaft near the discharge outlet is a buffer shaft, and the buffer shaft is fixedly connected with a buffer unit; the drive unit and the slow-stop unit are both located inside the isolation cover, and the drive unit and the slow-stop unit are connected through a transmission unit; The driving unit includes a motor frame, a driving motor, and a locking unit. The motor frame is fixedly connected to the baffle. The motor frame is slidably connected to the driving motor, and a sliding hole is formed on the surface of the motor frame. One side of the driving motor close to the motor frame is fixedly connected with a hinge shaft, the hinge shaft is slidably connected with the sliding hole, and the hinge shaft is hinged to the transmission unit. A first spring is fixedly connected between the side of the driving motor away from the motor frame and the baffle. An electromagnet is arranged at the output end of the driving motor, and the output shaft of the driving motor is slidably connected with the locking unit. The side of the locking unit away from the driving motor is fixedly connected with a driving shaft, and the locking unit is made of iron. The locking unit is used to lock with the output shaft of the driving motor for synchronous rotation.

[0006] With the above technical solution, when the equipment is running normally, the magnetism between the electromagnet at the output end of the driving motor and the locking unit can attract each other. Since the locking unit is fixedly connected to the driving shaft, only the driving motor will move. When the driving motor moves, it will compress the first spring. When the driving motor locks with the locking unit, the driving motor can drive the transmission unit to convey items. In the present invention, when the equipment stops due to non-emergency or power outage, the driving motor will stop running when it loses power, and at the same time, the electromagnet will also lose locking with the locking unit. The first spring will push the driving motor away from the locking unit. When the hinge shaft moves, it will push the transmission unit to move. Since the transmission unit is not directly connected to the driving motor, after the power is cut off, the driving motor will not directly stop the transmission unit, but the transmission unit will continue to drive according to inertia to prevent the items on the transmission unit from tipping due to inertia when suddenly stopping, and avoid damage to the items caused by tipping.

[0007] Further, the transmission unit includes a support frame and a connecting rod. The support frame is fixedly connected to the baffle. The support frame is hinged to the connecting rod. The hinge point between the support frame and the connecting rod is away from the center of the connecting rod and close to the driving unit. The connecting rod is hinged to the hinge shaft of the driving motor. The slow-down unit includes a hinge block. The hinge block is hinged to one end of the connecting rod away from the hinge shaft. A connecting block is fixedly connected to the bottom of the hinge block. A connecting hole is formed on the surface of the baffle. The connecting block is slidably connected in the connecting hole. The length of the connecting hole is longer than that of the connecting block, and it serves as a redundant space for the movement of the connecting block. A pressing hole is formed on the side of the connecting block close to the slow-down shaft. A pressing unit is slidably connected in the pressing hole.

[0008] With the above technical solution, since the hinge point between the support frame and the connecting rod is closer to the driving unit, when the driving unit pushes the connecting rod, only a short stroke is required to move the slow-stop unit by a large stroke; when the connecting rod pushes the hinge block and the connecting block to move, the pressing unit will contact the slow-stop shaft, and the equipment will be slowly stopped by the frictional force; the way of stopping by frictional force can make the transmission unit stop slowly, which can avoid the items from tipping over due to rapid shutdown, and at the same time can avoid the impact of the inertia of the conveyor belt on the rotating shaft during emergency stop, thus increasing the service life.

[0009] Further, the pressing unit includes a pressing block, the pressing block is slidably connected to the pressing hole, a third spring is fixedly connected between the pressing block and the pressing hole, and a rotating groove is formed on one side of the pressing block away from the third spring; a damping wheel is rotatably connected in the rotating groove, and the damping wheel is hollow and made of a flexible material.

[0010] With the above technical solution, when the connecting block moves, it will drive the pressing block to move. Through the setting of the damping wheel, during use, the force of the third spring to reset the pressing block and the moving distance of the connecting block are used to make the damping wheel generate pressure on the slow-stop shaft, and at the same time, through the contact, a resistance is generated in the rotating direction of the slow-stop shaft by the damping wheel, but the generated resistance will not directly stop the slow-stop shaft, so that the slow-stop shaft will stop slowly. During use, the friction between the pressing unit and the slow-stop shaft can be changed into rotational friction, so that the wear generated during friction can be reduced when contacting the slow-stop shaft.

[0011] Further, an extension plate is fixedly connected to the top of the hinge block, and a hydraulic rod is fixedly connected to the bottom of one side of the extension plate, and the hydraulic rod is slidably connected to the buffer unit; The buffer unit includes a connecting plate, the connecting plate is located at the discharge port of the conveyor belt, both sides of the bottom of the connecting plate are hinged to the baffle, and a connecting rod is fixedly connected to one side of the connecting plate; the connecting rod penetrates through the baffle and is rotatably connected to the baffle, and a second gear is fixedly connected to the end of the connecting rod away from the connecting plate; a first gear is meshed on the left side of the second gear; a hydraulic column is fixedly connected to the side of the first gear away from the baffle, a connecting shaft is clamped on the side of the first gear close to the baffle, the connecting shaft is fixedly connected to the buffer shaft, and the length of the connecting shaft is half of the thickness of the second gear; a hydraulic gear rack is slidably connected to the outer wall of the hydraulic column; the hydraulic gear rack is communicated with the hydraulic tank through a hydraulic pipe; sliding grooves are formed on both sides of one end of the connecting block close to the hinge block, and the inner wall of the sliding groove close to the hydraulic tank is slidably connected to the hydraulic tank; the inner wall of the hydraulic tank is slidably connected to the hydraulic rod, and the side of the hydraulic tank close to the baffle is slidably connected to the baffle.

[0012] With the above technical solution, while the device is slowly stopping, the hydraulic rod is pushed into the interior of the hydraulic tank by the downward pressure of the hinge block, and the first gear is pushed to move through the hydraulic pipe. Since the connecting shaft is connected to the buffer shaft, the first gear will generate power, and the second gear will drive the connecting plate to rotate around the connecting rod as the axis through meshing with the second gear, so that the connecting plate is lifted to block the items on the transmission unit from continuing to move. At this time, the connecting plate is lifted by the remaining power of the buffer shaft, thus realizing that it can still be lifted even when power is cut off, and protecting the items from falling or leaving the transmission unit; When the lifting angle of the connecting plate is perpendicular to the transmission unit, it may cause subsequent items to impact the front items and unable to unload the force, resulting in possible breakage of fragile items due to the impact; Since the transmission unit will be frictionally decelerated by the deceleration unit, the lifting angle of the connecting plate will not be perpendicular to the transmission unit, so that the connecting plate can be tilted outwards. When the transmission unit is slowly stopping, some items will slide onto the connecting plate due to inertia, but due to the tilt of the connecting plate, the front items can move onto the connecting plate to unload the force when the subsequent items impact, and the tilted connecting plate can make the items move back under the influence of gravity, so that they will not stay on the connecting plate for a long time; At the same time, since the transmission unit is already in a slow stop state, the impact of subsequent items will also become smaller; During normal use, the first gear is not connected to the connecting shaft and the second gear. At this time, the connecting plate will rotate downward under the influence of gravity, and at this time, the connecting plate can be placed on the subsequent device to transfer the items to the subsequent device.

[0013] Further, the locking unit includes a locking housing, one side of the locking housing away from the drive motor is fixedly connected to the drive shaft, a locking hole is provided on the inner wall of the locking housing, a locking block is slidably connected to the inner wall of the locking hole, and the locking block is connected to the locking hole through a second spring; Both the locking block and the locking housing are made of iron; Two clamping blocks are fixedly connected to the side of the electromagnet close to the locking unit, and the clamping blocks are in contact with the locking block.

[0014] With the above technical solution, through the setting of the clamping block and the locking block, the locking block can be sucked outwards when the electromagnet is energized. Through the contact between the clamping block and the locking block, the output shaft of the drive motor drives the locking housing to rotate when rotating, so that the drive shaft rotates, thereby driving the transmission unit to operate; When the device is powered off, the attraction of the electromagnet will disappear instantly. At this time, the locking block and the locking housing will lose the magnetic attraction of the electromagnet, and the locking block will be reset under the traction of the second spring. At the same time, the drive motor will also be reset under the force of the first spring, so that the drive motor can be disengaged from the locking housing.

[0015] Further, a buffer plate is provided on the side of the extension plate away from the hydraulic rod. The buffer plate is connected to the extension plate by a fourth spring. The inner wall of the sliding groove away from the hydraulic tank is slidably connected to the buffer plate, and the buffer plate contacts the baffle.

[0016] With the above technical solution, when the hinge block and the connection block move, the buffer plate and the baffle are always in contact, and the buffer plate can store energy due to the shortening of the distance between the buffer plate and the baffle through the setting of the fourth spring. During the energy storage process, the force of the driving unit on the transmission unit can be reduced, thereby avoiding the too-fast contact between the pressing block and the slow-stop shaft and preventing the slow-stop shaft from being subjected to a large force and quickly stopping.

[0017] Further, a tensioning unit is fixedly connected between the baffles. The tensioning unit includes a fixing frame, both ends of the fixing frame are fixedly connected to the baffles, a plurality of tensioning holes are opened at the bottom of the baffles, a tensioning frame is slidably connected to the inner wall of the tensioning holes, the tensioning frame is connected to the tensioning holes by a fifth spring, a tensioning wheel is rotatably connected to the inner wall of the tensioning frame near the bottom, and the tensioning wheel is rotatably connected to the transmission belt.

[0018] With the above technical solution, in order to prevent breakage, the transmission belt can use a longer redundancy, and the tensioning unit is used to maintain the tension of the transmission belt. Under normal circumstances, the fifth spring will push the tensioning frame to make the tensioning wheel contact the transmission belt, and thereby tighten the redundancy of the transmission belt; when a heavy object stretches the transmission belt, the transmission belt in contact with the tensioning wheel will be pulled, and the tensioning wheel will move upward. At this time, the tensioning frame will compress the fifth spring and keep the transmission belt in a suitable tension range.

[0019] Further, an air cylinder housing is fixed on the side of the connection block away from the pressing block, and an air cylinder hole is opened on the same side of the connection block; an air cylinder plate is slidably connected to the inner wall of the air cylinder housing, and the air cylinder housing is fixedly connected to the isolation cover by an air pressure pipe on the side away from the connection block; an emergency stop button is slidably connected to the end of the air pressure pipe away from the air cylinder housing; the emergency stop button is used to quickly stop the equipment, and the emergency stop button is electrically connected to the power supply of the equipment.

[0020] With the above technical solution, when a person is involved in the transmission belt or other situations occur, the equipment can be powered off by pressing the emergency stop button. At the same time of power off, the air inside the air pressure pipe will be pushed, and the air flow will be introduced into the starting housing and push the air cylinder plate to move. At this time, the air cylinder plate will push the air to move from the air cylinder hole into the pressing hole. Since the air pressure in the pressing hole increases, the pressing block will be continuously pushed outward and the pressing block cannot be reset, thereby quickly stopping the equipment and achieving the effect of emergency stop.

[0021] The present invention has the following beneficial effects: 1. When the invention stops under non-emergency conditions or encounters a power outage, the driving motor loses power and stops. At the same time, the electromagnet also loses its lock with the locking unit, and the first spring will push the driving motor away from the locking unit. While the hinge shaft moves, it will push the transmission unit to move. Since the transmission unit is not directly connected to the driving motor, after the device loses power, the driving motor will not directly stop the transmission unit, but the transmission unit will continue to drive according to inertia to prevent the items on the transmission unit from tipping due to inertia caused by an instant stop and avoid damage caused by tipping.

[0022] 2. Since the hinge point between the support frame and the connecting rod of the invention is closer to the driving unit, when the driving unit pushes the connecting rod, only a short stroke is required to make the slow-stop unit move a large distance. When the connecting rod pushes the hinge block and the connecting block to move, it will make the pressing unit contact the slow-stop shaft and make the device stop slowly through friction. The way of stopping through friction can make the transmission unit stop slowly, which can avoid the items from tipping due to a rapid stop and also avoid the impact of the inertia of the transmission belt on the stopped rotating shaft during an emergency stop, thereby increasing the service life.

[0023] 3. When the invention presses down the hinge block, the hydraulic rod moves into the interior of the hydraulic tank, and through the hydraulic pipe, it pushes the first gear to move. Since the connecting shaft is connected to the buffer shaft, the first gear will generate power, and through meshing with the second gear, the second gear drives the connecting plate to rotate around the connecting rod as the axis, so that the connecting plate rises to block the items on the transmission unit from continuing to move. At this time, the connecting plate rises by the remaining power of the buffer shaft, thereby realizing that it can still rise even when the power is off and protecting the items from falling or leaving the transmission unit.

[0027] 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 making creative efforts belong to the scope of protection of the present invention.

[0028] Please refer to Figures 1-10 As shown, the present invention is a warehousing goods conveying device, including a transmission unit 1. The transmission unit 1 includes a transmission belt 11. Both sides of the transmission belt 11 are fixedly connected with baffles 12. A plurality of rotating shafts 13 are meshed on the inner surface of the transmission belt 11; the rotating shafts 13 all penetrate through the baffles 12 and are rotatably connected with the baffles 12; one side of the baffle 12 is fixedly connected with an isolation cover 14, and the bottom of the baffle 12 and the isolation cover 14 is fixedly connected with a bracket 17; the bracket 17 is used to support the device; one side of the transmission belt 11 is the feed inlet, and the other side is the discharge outlet; The rotating shaft 13 on the side close to the feeding port is the driving shaft, and the driving shaft is fixedly connected to the driving unit 2; the rotating shaft 13 adjacent to the driving shaft is the deceleration stop shaft, and the deceleration stop shaft is slidably connected to the deceleration stop unit 3; the rotating shaft 13 close to the discharging port is the buffer shaft, and the buffer shaft is fixedly connected to the buffer unit 4; both the driving unit 2 and the deceleration stop unit 3 are located inside the isolation cover 14, and the driving unit 2 and the deceleration stop unit 3 are connected by a transmission unit 5; The driving unit 2 includes a motor frame 21, a driving motor 22 and a locking unit 7. The motor frame 21 is fixedly connected to the baffle 12, the motor frame 21 is slidably connected to the driving motor 22, and a sliding hole is formed on the surface of the motor frame 21; a hinge shaft is fixedly connected to the side of the driving motor 22 close to the motor frame 21, the hinge shaft is slidably connected to the sliding hole, and the hinge shaft is hinged to the transmission unit 5; a first spring 24 is fixedly connected between the side of the driving motor 22 away from the motor frame 21 and the baffle 12, an electromagnet is arranged at the output end of the driving motor 22, and the output shaft of the driving motor 22 is slidably connected to the locking unit 7; the side of the locking unit 7 away from the driving motor 22 is fixedly connected to the driving shaft, and the locking unit 7 is made of iron; the locking unit 7 is used to lock with the output shaft of the driving motor 22 for synchronous rotation.

[0029] In this embodiment, considering that the equipment may need to be stopped during operation, since the existing transmission unit 1 is usually directly connected to the driving motor 22, when the driving motor 22 loses power, it will stop instantly, and at the same time, the transmission unit 1 will stop. When conveying items, the items may fall due to inertia. When the conveyed items are fragile items, the fragile items may fall and break, causing property losses; at the same time, when encountering power outages or power trips, the items will also fall; When the equipment is running normally, the magnetism between the electromagnet at the output end of the driving motor 22 and the locking unit 7 can attract each other. Since the locking unit 7 is fixed to the driving shaft, only the driving motor 22 will move. When the driving motor 22 moves, it will compress the first spring 24. When the driving motor 22 is locked with the locking unit 7, the driving motor 22 can drive the transmission unit 1 to convey items; When stopping the machine in non-emergency situations or encountering a power outage, the driving motor 22 loses power and stops. At the same time, since the electromagnet loses power, it will also lose the lock with the locking unit 7. At the same time, under the action of the first spring 24, the driving motor 22 will completely disengage from the locking unit 7, and the driving motor 22 will slide on the motor frame 21 through the hinge shaft. When the hinge shaft moves, it will push the transmission unit 5 to move; By using the above method, the transmission unit 1 is not directly connected to the drive motor 22. After the device is powered off, the drive motor 22 will not directly stop the transmission unit 1. Instead, the transmission unit 1 will continue to transmit according to inertia, so as to prevent the items on the transmission unit 1 from toppling due to inertia caused by instant stop, and avoid the damage caused by the toppling of the items.

[0030] Specifically, the transmission unit 5 includes a support frame 51 and a connecting rod 52. The support frame 51 is fixedly connected to the baffle 12. The support frame 51 is hinged to the connecting rod 52. The hinge between the support frame 51 and the connecting rod 52 is far from the center of the connecting rod 52 and close to the drive unit 2; the connecting rod 52 is hinged to the hinge shaft of the drive motor 22; The slow stop unit 3 includes a hinge block 31. The hinge block 31 is hinged to one end of the connecting rod 52 far from the hinge shaft. A connecting block 32 is fixedly connected to the bottom of the hinge block 31; a connecting hole is formed on the surface of the baffle 12. The connecting block 32 is slidably connected in the connecting hole. The length of the connecting hole is longer than that of the connecting block 32 and serves as a redundant space for the movement of the connecting block 32. A pressing hole is formed on one side of the connecting block 32 close to the slow stop shaft; a pressing unit 8 is slidably connected in the pressing hole.

[0031] In this embodiment, considering that the transmission unit 1 will continue to transmit by inertia after power off, if the tail of the transmission unit 1 is blocked, it may cause the items to collide with each other due to the blockage, which may cause the items to be damaged due to the collision, or may be thrown out of the device due to excessive inertia; When the drive unit 2 moves the transmission unit 5 due to shutdown, since the hinge between the support frame 51 and the connecting rod 52 is closer to the drive unit 2, when the drive unit 2 pushes the connecting rod 52, only a short stroke is required to make the slow stop unit 3 move a large stroke; When the connecting rod 52 pushes the hinge block 31 to move, it will also push the connecting block 32 to move. Since the connecting rod 52 will rotate in an arc when pushing the hinge block 31 to move, at this time, the hinge block 31 and the connecting block 32 will follow and rotate in an arc, and make the connecting block 32 closer to the slow stop shaft, so that the pressing unit 8 contacts the slow stop shaft, and the device is slowly stopped through friction; Through the above operations, the drive unit 2 can make the transmission unit 1 slowly stop through friction after shutdown. The way of stopping through friction can make the transmission unit 1 slowly stop, which can avoid the items from toppling due to rapid shutdown, and at the same time can avoid the impact of the inertia of the transmission belt 11 on the stopped slow stop shaft during emergency stop, thus increasing the service life.

[0032] Specifically, the pressing unit 8 includes a pressing block 33. The pressing block 33 is slidably connected to the pressing hole, and a third spring 35 is fixedly connected between the pressing block 33 and the pressing hole. A rotating groove is formed on the side of the pressing block 33 away from the third spring 35; a damping wheel 34 is rotatably connected in the rotating groove. The damping wheel 34 is hollow and made of a flexible material.

[0033] In this embodiment, considering that there will be losses when the pressing unit 8 rubs against the slow-stop shaft, after long-term use, the contact area may become smaller due to friction or the transmission unit 1 may not be able to stop due to non-contact, and at the same time, the losses caused by friction will also reduce the service life of the device; When the connecting block 32 moves, it will drive the pressing block 33 to move. Through the setting of the damping wheel 34, during use, the force of the third spring 35 to reset the pressing block 33 and the moving distance of the connecting block 32 are used to make the damping wheel 34 exert pressure on the slow-stop shaft. At the same time, through contact, a resistance is generated in the rotating direction of the slow-stop shaft by the damping wheel 34, but the generated resistance will not directly stop the slow-stop shaft, so that the slow-stop shaft will stop slowly. When in use, the friction between the pressing unit 8 and the slow-stop shaft can be changed into rotational friction, so that the wear generated during friction can be reduced when contacting the slow-stop shaft; Since the damping wheel 34 is hollow and made of a flexible material, the inside of the damping wheel 34 is filled with air during use. When the impact force on the slow-stop shaft is large, it can be buffered by the internal air. And when the pressure is large, the slow-stop shaft can push the air inside the damping wheel 34 and make the slow-stop shaft directly contact the pressing block 33, so as to obtain a larger contact area and a faster braking speed.

[0034] Specifically, an extension plate 312 is fixedly connected to the top of the hinge block 31. A hydraulic rod is fixedly connected to the bottom of one side of the extension plate 312. The hydraulic rod is slidably connected to the buffer unit 4; The buffer unit 4 includes a connecting plate 18 which is located at the discharge port of the conveyor belt 11. Both sides of the bottom of the connecting plate 18 are hinged to the baffle 12. One side of the connecting plate 18 is fixedly connected with a connecting rod; the connecting rod penetrates through the baffle 12 and is rotatably connected with the baffle 12. The end of the connecting rod away from the connecting plate 18 is fixedly connected with a second gear 45; a first gear 44 is meshed with the left side of the second gear 45; a hydraulic column is fixedly connected to the side of the first gear 44 away from the baffle 12. A connecting shaft 46 is clamped to the side of the first gear 44 close to the baffle 12. The connecting shaft 46 is fixedly connected with the buffer shaft. The length of the connecting shaft 46 is half of the thickness of the second gear 45; a hydraulic gear rack 43 is slidably connected to the outer wall of the hydraulic column; the hydraulic gear rack 43 is communicated with the hydraulic tank 41 through a hydraulic pipe 42; sliding grooves are formed on both sides of one end of the connecting block 32 close to the hinge block 31. The inner wall of the sliding groove close to the hydraulic tank 41 is slidably connected with the hydraulic tank 41; a hydraulic rod is slidably connected to the inner wall of the hydraulic tank 41. The side of the hydraulic tank 41 close to the baffle 12 is slidably connected with the baffle 12.

[0035] In this embodiment, considering that when the equipment is actively shut down, it may be a problem with the subsequent equipment. When the transmission unit 1 slowly stops, the items on the transmission unit 1 may still be transferred to the subsequent equipment. While the equipment is slowly stopping, the downward pressure of the hinge block 31 causes the hydraulic rod to move into the interior of the hydraulic tank 41, and the hydraulic power is transmitted to the hydraulic gear rack 43 through the hydraulic pipe 42, and the first gear 44 is pushed to move. Since the height of the connecting shaft 46 is half of that of the second gear 45, when the first gear 44 moves, it will first mesh with the second gear 45 and then be clamped with the connecting shaft 46. At this time, when the connecting shaft 46 is connected to the buffer shaft, power will be generated on the first gear 44, and through the meshing with the second gear 45, the second gear 45 will drive the connecting plate 18 to rotate around the connecting rod as the axis, so that the connecting plate 18 is lifted to block the items on the transmission unit 1 from continuing to move. At this time, the connecting plate 18 is lifted by the remaining power of the buffer shaft, thus realizing that it can still be lifted even when powered off, and protecting the items from falling or leaving the transmission unit 1; when the lifting angle of the connecting plate 18 is perpendicular to the transmission unit 1, it may cause subsequent items to impact the front items and unable to unload the force, resulting in possible breakage of fragile items due to the impact; since the transmission unit 1 will be frictionally decelerated by the deceleration unit 3, the lifting angle of the connecting plate 18 will not be perpendicular to the transmission unit 1, so that the connecting plate 18 can be tilted outwards. When the transmission unit 1 slowly stops, some items will slide onto the connecting plate 18 due to inertia. However, due to the inclination of the connecting plate 18, when subsequent items impact, the front items can move onto the connecting plate 18 to unload the force, and the inclined connecting plate 18 can make the items move back under the action of gravity, so that they will not stay on the connecting plate 18 for a long time; at the same time, since the transmission unit 1 is already in a slow stop state, the impact of subsequent items will also become smaller. During normal use, the first gear 44 is not connected to the connecting shaft 46 and the second gear 45. At this time, the connecting plate 18 will rotate downward under the influence of gravity. At this time, the connecting plate 18 can be placed on the subsequent equipment, and thus items can be transferred to the subsequent equipment.

[0036] Specifically, the locking unit 7 includes a locking housing 23. One side of the locking housing 23 away from the drive motor 22 is fixedly connected to the drive shaft. A locking hole is provided in the inner wall of the locking housing 23. A locking block 26 is slidably connected to the inner wall of the locking hole. The locking block 26 and the locking hole are connected by a second spring 25; both the locking block 26 and the locking housing 23 are made of iron; two clamping blocks are fixedly connected to one side of the electromagnet close to the locking unit 7, and the clamping blocks are in contact with the locking block 26.

[0037] In this embodiment, considering that when encountering items with a relatively large weight, the magnetic suction force of the electromagnet may be insufficient to cause normal rotation; through the arrangement of the clamping blocks and the locking block 26, the locking block 26 can be sucked outwards when the electromagnet is energized. Through the contact between the clamping blocks and the locking block 26, the output shaft of the drive motor 22 drives the locking housing 23 to rotate when rotating, so as to drive the drive shaft to rotate, thereby driving the transmission unit 1 to operate; When the device is powered off, the attraction of the electromagnet will disappear instantly. At this time, the locking block 26 and the locking housing 23 will lose the magnetic suction force of the electromagnet. The locking block 26 will be reset under the traction of the second spring 25, and at the same time, the drive motor 22 will also be reset under the force of the first spring 24, thereby enabling the drive motor 22 to disengage from the locking housing 23.

[0038] Specifically, there is a buffer plate 36 on the side of the hinge block 31 away from the hydraulic rod. The buffer plate 36 and the extension plate 312 are connected by a fourth spring 37. The inner wall of the sliding groove away from the hydraulic tank 41 is slidably connected to the buffer plate 36, and the buffer plate 36 is in contact with the baffle 12.

[0039] In this embodiment, considering that when the hinge block 31 drives the connecting block 32 to move, the pressing unit 8 may directly contact the slow-stop shaft due to too fast and too large a force, and a relatively large pressure may be generated, which may cause the pressing unit 8 and the slow-stop shaft to be damaged by impact due to a relatively fast speed. At the same time, the relatively large pressure will also cause the slow-stop shaft to stop quickly, resulting in the items on the transmission unit 1 falling due to inertia; When the hinge block 31 and the connecting block 32 move, the buffer plate 36 and the baffle 12 are always in contact. And through the arrangement of the fourth spring 37, the buffer plate 36 can store energy because the distance between it and the baffle 12 is shortened. During the energy storage process, the force of the drive unit 2 on the transmission unit 5 can be slowed down, thereby avoiding the pressing block 33 from contacting the slow-stop shaft too quickly and avoiding the slow-stop shaft from being quickly stopped due to a relatively large force.

[0040] Specifically, a tensioning unit 6 is fixedly connected between the baffles 12. The tensioning unit 6 includes a fixing frame 61, both ends of the fixing frame 61 are fixedly connected to the baffles 12, a plurality of tensioning holes are formed in the bottom of the baffles 12, a tensioning frame 62 is slidably connected to the inner wall of the tensioning holes, the tensioning frame 62 is connected to the tensioning holes through a fifth spring 63, a tensioning wheel 64 is rotatably connected to the inner wall of the tensioning frame 62 near the bottom, and the tensioning wheel 64 is rotatably connected to the transmission belt 11.

[0041] In this embodiment, considering that the transmission belt 11 usually leaves a length redundancy to prevent breakage, but too short a redundancy may still break when carrying heavy objects, and too long a redundancy may cause the rotating shaft 13 to be unable to transmit the transmission belt 11 normally, resulting in the transmission belt 11 not operating properly; To prevent breakage, the transmission belt 11 can use a longer redundancy, and the tensioning unit 6 is used to maintain the tension of the transmission belt 11. Under normal circumstances, the fifth spring 63 will push the tensioning frame 62 to make the tensioning wheel 64 contact the transmission belt 11, and thus tighten the redundancy of the transmission belt 11; when a heavier object causes the transmission belt 11 to be stretched, the transmission belt 11 in contact with the tensioning wheel 64 will be pulled, and the tensioning wheel 64 will move upward. At this time, the tensioning frame 62 will compress the fifth spring 63 and keep the transmission belt 11 in a suitable tension range.

[0042] Specifically, a pneumatic housing 38 is fixed to the side of the connecting block 32 away from the pressing block 33, and a pneumatic hole is formed in the same side of the connecting block 32; a pneumatic plate 39 is slidably connected to the inner wall of the pneumatic housing 38, and the side of the pneumatic housing 38 away from the connecting block 32 is fixedly connected to the isolation cover 14 through a pneumatic tube 16. The end of the pneumatic tube 16 away from the pneumatic housing 38 is slidably connected to an emergency stop button 15; the emergency stop button 15 is used to quickly stop the equipment, and the emergency stop button 15 is electrically connected to the power supply of the equipment.

[0043] In this embodiment, when a person is involved in the transmission belt 11 or other situations occur, pressing the emergency stop button 15 can cut off the power supply of the equipment, and at the same time, it will push the air inside the pneumatic tube 16, and the air flow will be introduced into the starting housing and push the pneumatic plate 39 to move. At this time, the pneumatic plate 39 will push the air to move from the pneumatic hole into the pressing hole. Since the air pressure in the pressing hole increases, it will continuously push the pressing block outward and prevent the pressing block from resetting. Thus, the equipment can be quickly stopped, achieving the effect of emergency stop.

[0044] During use, First, when the device is operating normally, the locking block 26 can be sucked outwards when the electromagnet is energized through the setting of the clamping block and the locking block 26. Since the locking housing 23 is fixed to the drive shaft, only the drive motor 22 will move. When the drive motor 22 moves, it will compress the first spring 24. Through the contact between the clamping block and the locking block 26, the output shaft of the drive motor 22 will drive the locking housing 23 to rotate when rotating, so that the drive shaft rotates, thereby driving the transmission unit 1 to operate; During normal use, the first gear 44 is not connected to the connecting shaft 46 and the second gear 45. At this time, the connecting plate 18 will rotate downward under the influence of gravity. At this time, the connecting plate 18 can be placed on the subsequent device, thereby transmitting items to the subsequent device.

[0045] Secondly, when the device stops due to non-emergency or power failure, the drive motor 22 will lose power and stop. At the same time, since the electromagnet loses power, it will also lose the lock with the locking unit 7. At the same time, under the action of the first spring 24, the drive motor 22 will completely disengage from the locking unit 7, and the drive motor 22 will slide on the motor frame 21 through the hinge shaft. When the hinge shaft moves, it will push the transmission unit 5 to move; since the transmission unit 1 is not directly connected to the drive motor 22, after the power is cut off, the drive motor 22 will not directly stop the transmission unit 1, but the transmission unit 1 will continue to drive according to inertia to prevent the items on the transmission unit 1 from tipping due to inertia caused by sudden stop, and avoid damage caused by tipping of the items; When the drive unit 2 moves the transmission unit 5 due to shutdown, since the hinge point between the support frame 51 and the connecting rod 52 is closer to the drive unit 2, when the drive unit 2 pushes the connecting rod 52, only a short stroke is required to make the slow stop unit 3 move a large stroke; When the connecting rod 52 pushes the hinge block 31 to move, it will also push the connecting block 32 to move. Since the connecting rod 52 will rotate in an arc when pushing the hinge block 31 to move, at this time, the hinge block 31 and the connecting block 32 will follow and rotate in an arc, and make the connecting block 32 closer to the slow stop shaft, so that the pressing unit 8 contacts the slow stop shaft, and the device stops slowly through friction.

[0046] At the same time, in order to prevent breakage, the transmission belt 11 can use a longer redundancy, and the tension of the transmission belt 11 is maintained by the tensioning unit 6. Under normal circumstances, the fifth spring 63 will push the tensioning frame 62, so that the tensioning wheel 64 contacts the transmission belt 11, and thereby tightens the redundancy of the transmission belt 11; when encountering heavier items that stretch the transmission belt 11, the transmission belt 11 in contact with the tensioning wheel 64 will be pulled, and the tensioning wheel 64 will move upward. At this time, the tensioning frame 62 will compress the fifth spring 63, and keep the transmission belt 11 in a suitable tension range.

[0047] Finally, while the device is slowly stopping, the hydraulic rod is moved into the interior of the hydraulic tank 41 by the downward pressure of the hinge block 31, and the power of the hydraulic pressure is transmitted to the hydraulic gear rack 43 through the hydraulic pipe 42, and the first gear 44 is pushed to move. Since the height of the connecting shaft 46 is half of that of the second gear 45, when the first gear 44 moves, it will first engage with the second gear 45 and then be clamped with the connecting shaft 46. At this time, when the connecting shaft 46 is connected to the buffer shaft, power will be generated on the first gear 44, and through the engagement with the second gear 45, the second gear 45 will drive the connecting plate 18 to rotate around the connecting rod as the axis, so that the connecting plate 18 is lifted to block the items on the transmission unit 1 from continuing to move. At this time, the connecting plate 18 is lifted by the remaining power of the buffer shaft, thus realizing that it can still be lifted even when power is cut off, and protecting the items from falling or leaving the transmission unit 1; when the lifting angle of the connecting plate 18 is perpendicular to the transmission unit 1, it may cause subsequent items to impact the front items and unable to unload the force, resulting in fragile items possibly being broken due to the impact; since the transmission unit 1 will be frictionally decelerated by the deceleration unit 3, the lifting angle of the connecting plate 18 will not be perpendicular to the transmission unit 1, so that the connecting plate 18 can be inclined outwards. When the transmission unit 1 is slowly stopping, some items will slide onto the connecting plate 18 due to inertia, but due to the inclination of the connecting plate 18, when subsequent items impact, the front items can move onto the connecting plate 18 to unload the force, and the inclined connecting plate 18 can make the items move back due to gravity, so that they will not stay on the connecting plate 18 for a long time; at the same time, since the transmission unit 1 is already in a slowly stopping state, the impact of subsequent items will also become smaller.

[0048] When an emergency occurs, the device can be powered off by pressing the emergency stop button 15, and at the same time of power off, the air inside the air pressure pipe 16 will be pushed, and the air flow will be introduced into the starting housing and push the pneumatic plate 39 to move. At this time, the pneumatic plate 39 will push the air to move from the pneumatic hole into the pressing hole. Since the air pressure in the pressing hole increases, the pressing block will be continuously pushed outwards and the pressing block cannot be reset, so that the device can be quickly stopped, thus achieving the effect of emergency stop; When the pressure is relatively high, the deceleration shaft can push the air inside the damping wheel 34, and the deceleration shaft is in direct contact with the pressing block 33, so that a larger contact area can be obtained and a faster braking speed can be obtained.
