Description

TECHNICAL FIELD

[0001] The present application relates to the field of material transportation, in particular to a chain type automatic feeding machine. BACKGROUND

[0002] The product production process refers to the whole process from the input of raw materials to the output of finished products, usually including process, inspection, transportation, waiting and natural processes. The process is the most basic part of the production process, and the formation of a product usually involves multiple processes, each of which corresponds to a specially customized production equipment. The automatic feeding machine is a commonly used material conveying equipment in the production workshop, such as commonly used screw conveyors, belt conveyors, etc., which plays a role in transferring materials between production equipment responsible for different processes, and has an important influence on reducing the labor intensity of workers.

[0003] Taking the applicant's main production of a heating bag product as an example, the heating bag is a kind of external application instrument with self-heating property, which promotes the local blood circulation of human body by the principle of hot compress. The production process of the heating bag is as follows: the first step is the production of the heating bag, the heating agent is manufactured into an independent heating bag by the heating bag production equipment, and the heating bag is transferred by the horizontally arranged conveying belt connected to the discharge port of the heating bag production equipment; the second step is the production of the finished heating bag, the independent heating bag is conveyed to the equipment for producing the finished heating bag for processing; finally, the complete independent packaged heating bag product is output through the automatic material placing equipment connected behind the equipment for producing the finished heating bag.

[0004] Because the heating bag production equipment is low in height, the conveying belt connected behind the equipment is also set to be lower than the equipment for producing the finished heating bag, thereby forming a certain height difference, which needs to be fed from a high place. The existing technology generally uses a bucket elevator or a screw conveyor to feed from a low place to a high place, but because the outer surface of the heating bag is generally made of light materials such as non-woven fabric and breathable film, if a screw conveyor is used, the high-speed rotating spiral blade in the screw conveyor is easy to scratch or contaminate the outer surface of the heating bag, and if a bucket elevator is used, the edge of the bucket is also easy to scratch the outer surface of the heating bag in the process of scooping up the heating bag, so an automatic feeding machine for transferring the heating bag and other fragile materials is urgently needed to ensure that the feeding process will not damage the surface of the material. SUMMARY

[0005] The present application aims to provide a chain type automatic feeding machine, which can solve the technical problem that the surface of the material is easy to be damaged during feeding.

[0006] To achieve the above purpose, the present application adopts the following technical scheme:

[0007] The utility model provides a chain automatic feeding machine, including frame and the lifting mechanism of installation on frame, lifting mechanism includes chain, still include the bunker and the slide channel of installation on the side end of frame, the bunker includes the apron, the slide plate of fixed in the apron bottom, the magnetic attraction baffle of articulation with slide plate, slide plate is arranged obliquely, apron and chain detachable connection, fixedly set magnet on apron near the one side of magnetic attraction baffle, the top of frame is fixedly set with the upper wedge for opening magnetic attraction baffle, the bottom surface of upper wedge is the inclined plane that inclines to the side close to the bunker, and the bottom edge of upper wedge corresponds with magnet, the bottom of frame is fixedly set with the lower wedge for closing magnetic attraction baffle, and the top surface of lower wedge is the inclined plane that inclines to the side away from the bunker, and the top edge of lower wedge corresponds with the left 1 / 2 position of magnetic attraction baffle.

[0008] Beneficial effects:

[0009] When using, the bunker is first in the lowest position, and the material is conveyed from the front processing equipment to the bunker through the conveying belt, at this time, the bunker is in a closed state, that is, the magnetic attraction baffle is magnetically attracted and fixed with the magnet on the apron, after the material in the bunker is filled, the bunker is lifted upward by the chain lifting mechanism, the top of the frame is fixedly provided with an upper wedge, and the bottom surface of the upper wedge is an inclined surface that inclines to the side close to the bunker, when the bunker is lifted to the top surface of the magnetic attraction baffle contacts the bottom surface of the upper wedge, the upper wedge will give the magnetic attraction baffle a rightward thrust, so that the magnetic attraction baffle gradually moves away from the magnet until it is completely opened, at this time, the bunker is in an open state, since the slide plate is arranged obliquely, the material loaded in the bunker will fall along the slide plate into the slide channel, thereby completing the transfer and feeding of the material from a low place to a high place, and the surface of the material will not be damaged.

[0010] It is worth mentioning that the bottom surface of the upper wedge is an inclined surface that inclines to the side close to the bunker, if the bottom surface of the upper wedge is set to be horizontal, the problem that can easily be caused is that the upper wedge can only give the magnetic attraction baffle a vertical downward thrust, and cannot help the magnetic attraction baffle to separate from the magnetic attraction of the magnet, as for the fact that the bottom edge of the upper wedge corresponds with the magnet, it is to ensure that the contact between the top surface of the magnetic attraction baffle and the upper wedge starts from the inclined surface on the upper wedge, if the magnetic attraction baffle initially contacts the bottom edge of the upper wedge, it can also only give the upper wedge a vertical downward thrust.

[0011] When the bunker completes a feeding, the lifting mechanism is reversed to control the bunker to descend, the bottom of the frame is fixedly provided with a lower wedge, and the top edge of the lower wedge corresponds with the left 1 / 2 position of the magnetic attraction baffle, when the bunker is lowered to the bottom surface of the magnetic attraction baffle contacts the top edge of the lower wedge, in the process of continuous descent of the bunker, the lower wedge will give the magnetic attraction baffle an upward thrust until the magnetic attraction baffle is re-magnetically attracted and fixed with the magnet, at this time, the bunker is reset to the closed state to prepare for the next feeding.

[0012] It is worth mentioning that the top edge of the lower wedge corresponds to the left 1 / 2 position of the magnetic baffle. Through the inventor's experiment, when the top edge of the lower wedge corresponds to the left position of the upper magnetic baffle, the contact position of the lower wedge and the magnetic baffle is closer to the hinge of the magnetic baffle and the sliding plate. According to the principle of lever, the magnetic baffle will give the lower wedge greater friction. The top edge of the lower wedge is severely worn after a period of use and is prone to the situation that the lower wedge cannot push the magnetic baffle. Because the closer to the hinge, the lower wedge needs to give the magnetic baffle greater thrust to completely push the magnetic baffle. When the top edge of the lower wedge corresponds to the right position of the upper magnetic baffle, the magnetic baffle cannot approach the position that can produce magnetic field attraction with the magnet, so that the bin cannot be reset to the closed state.

[0013] Further, as an improvement, one end of the sliding channel near the bin is a positioning end, which can hard contact with the magnetic baffle during the descent of the bin.

[0014] Beneficial effect: when the bin is in an open state, i.e. the magnetic baffle is unfolded, if there is a gap between the magnetic baffle and the sliding channel, it is easy to cause the material in the bin to slip away from the gap. The positioning end can hard contact with the magnetic baffle during the descent of the bin, which can ensure the continuous sliding of the material.

[0015] Further, as an improvement, the lifting mechanism further comprises a U-shaped connecting plate, which comprises an integrally formed bottom plate and two side plates. The bottom plate is detachably connected to the side of the surrounding plate near the chain, and the side plate is detachably connected to the chain.

[0016] Beneficial effect: the U-shaped connecting plate can quickly connect the surrounding plate and the chain together, so that the bin can rise and fall under the assistance of the lifting mechanism. The detachable connection is convenient for workers to quickly install and disassemble the bin.

[0017] Further, as an improvement, the chain comprises a driving chain and a driven chain, and the lifting mechanism further comprises a driving wheel, a driven wheel, a motor, a driving wheel coaxially connected to the output end of the motor, a transmission wheel coaxially connected to the driving wheel, and a transmission chain installed between the transmission wheel and the driving wheel.

[0018] Beneficial effect: the motor and the transmission chain drive the rotation of the driving wheel and the driven wheel, so that the driving chain and the driven chain can drive the bin to rise and fall, which is an important structure to ensure the operation of the lifting mechanism.

[0019] Furthermore, as an improvement, the lifting mechanism includes a steel cable fixed to the frame and a sliding member fitted on the steel cable, with a fixing plate provided on the top of the enclosure, the fixing plate being detachably connected to the sliding member.

[0020] Beneficial effects: The sliding component can move vertically under the constraint of the steel cable, which helps to ensure that the running trajectory of the silo does not deviate from the direction, and mainly plays a guiding role.

[0021] Furthermore, as an improvement, the lifting mechanism includes a control cabinet mounted on a frame, wherein a controller with a timing module is installed inside the control cabinet, and the controller is electrically connected to the motor.

[0022] Beneficial effect: Controlling the final lifting height of the hopper using a controller with a timing module is a crucial control element to ensure the hopper smoothly reaches the correct position.

[0023] Furthermore, as an improvement, a set of fixing frames is arranged laterally on the side of the frame, and a vertically penetrating feed trough is attached to the fixing frames, with the sliding conveyor channel overlapping the top of the feed trough.

[0024] Beneficial effects: The feed trough is another set of equipment for processing materials. The feed trough is attached to the fixed frame on the side of the machine frame, which facilitates quick installation and disassembly by the staff. Attached Figure Description

The lifting mechanism 2 also includes a vertically arranged steel cable 27 fixed to the frame 1 by bolts and a sliding member 271 fitted on the steel cable 27. The sliding member 271 is T-shaped.

[0037] The lifting mechanism 2 also includes a control cabinet 28 installed on the frame 1. The control cabinet 28 contains a controller with a timing module, which is electrically connected to the motor 23.

[0038] Combination Figure 1 , 3 As shown in Figure 4, an upper wedge block 5 for opening the magnetic baffle 33 is welded to the top of the frame 1.

The bottom edge 52 of the upper wedge block 5 corresponds to the non-magnetic end on the magnet 34. A lower wedge block 6 for closing the magnetic baffle 33 is welded to the bottom of the frame 1. The top surface 61 of the lower wedge block 6 is an inclined surface that slopes away from the hopper 3. The top edge 62 of the lower wedge block 6 corresponds to the left 1 / 2 position of the magnetic baffle 33.

[0039] The conveyor channel 4 is a box that is closed on all sides and bottom 51 and open on top 61. The end of the conveyor channel 4 closest to the hopper 3 is the positioning end 41. During the descent of the hopper 3, the positioning end 41 can make hard contact with the magnetic baffle 33.

[0041] Application of a chain type automatic feeding machine in the production process of a heating bag

[0042] In use, the hopper 3 is first in the lowest position of the rack 1, and the independent heating bag is transferred into the hopper 3 by the heating bag production equipment through the conveying belt connected behind, at this time the hopper 3 is in a closed state, that is, the magnetic baffle 33 is magnetically attracted and fixed with the magnet 34 on the surrounding plate 31, when the hopper 3 is filled with heating bags (at this time the timing module in the controller experiences 5s), the chain type lifting mechanism 2 is used to lift the hopper 3 upward, specifically the motor 23 drives the driving wheel 24 arranged coaxially to rotate, then the transmission chain drives the driving wheel 211 and the driven wheel 221 to rotate, since the hopper 3 and the chain are connected together, the hopper 3 can be lifted and lowered under the drive of the motor 23, the upper wedge block 5 is fixedly arranged at the top of the rack 1 and the bottom surface 51 of the upper wedge block 5 is inclined towards the side close to the hopper 3, when the hopper 3 is lifted to the top surface 61 of the magnetic baffle 33 contacts with the bottom surface 51 of the upper wedge block 5, the upper wedge block 5 will give the magnetic baffle 33 a horizontal right pushing force Fx, so that the magnetic baffle 33 gradually moves away from the magnet 34 until it is completely opened, at this time the hopper 3 is in an open state, the timing module in the controller experiences 10s, the controller controls the motor 23 to stop rotating, since the sliding plate 32 is inclined arranged, at this time the heating bags loaded in the hopper 3 will fall along the sliding plate 32 into the sliding conveying channel 4, and finally the heating bags are put into the feeding chute 8 of the equipment for producing the finished product of the heating bag, so as to complete the transfer and feeding of the heating bags from low to high, and at the same time the surface of the heating bag will not be damaged, at this time the timing module in the controller experiences 5s, the controller controls the motor 23 to reverse to control the hopper 3 to descend.

[0043] The process of descending the hopper 3 is as follows: the lower wedge block 6 is welded at the bottom of the rack 1, and the top edge 62 of the lower wedge block 6 corresponds to the left 1 / 2 position of the magnetic baffle 33, when the hopper 3 descends to the bottom surface 51 of the magnetic baffle 33 contacts with the top edge 62 of the lower wedge block 6, in the process of continuing to descend the hopper 3, the lower wedge block 6 will give the magnetic baffle 33 an upward pushing force until the magnetic baffle 33 is re-magnetically attracted and fixed with the magnet 34, at this time the hopper 3 is reset to the closed state to prepare for the next feeding.

[0044] Example two

[0045] Compared with example one, the difference of this embodiment is that the combination of the hopper 3 and the lifting mechanism 2 is realized by the chain type lifting mechanism 2, and the hopper 3 is connected with the chain of the lifting mechanism 2. Figure 5 , Figure 6As shown, a cover plate 35 is hinged to the top of the surrounding plate 31 at the end where the magnet 34 is arranged. The cover plate 35 is used to seal the top of the hopper 3. The purpose of this arrangement is that the independent heat packs are transferred into the hopper 3 by the heat pack production equipment through the connecting conveyor belt. The heat packs cannot be regularly stacked in the hopper 3. Even if the heat packs can just fill the hopper 3 when the timing module in the controller experiences 5s in the first embodiment, the topmost heat pack will inevitably be exposed at the edge of the surrounding plate 31. The exposed part of the heat pack can contact the driving chain 21 or the driven chain 22 during the rising process of the hopper 3, and thus there is a possibility of damaging the surface of part of the heat pack.

[0046] At the bottom of the frame 1 Figure 6 As shown, two horizontal blocking rods 11 are welded on the left side. When the hopper 3 is at the lowest position of the frame 1, the two blocking rods can lift the two sides of the cover plate 35 to a 45° angle with the horizontal plane, so that the heat packs can be smoothly transferred into the hopper 3. When the hopper 3 needs to be raised after being filled with the heat packs, the cover plate 35 will automatically close without the limiting of the blocking rods 11, which protects the topmost heat pack in the hopper 3.

[0047] The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of characteristics in the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application. These will not affect the effect of the implementation of the present application and the practicality of the patent. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
