Description

Technical Field

[0001] The utility model relates to the field of material transportation, in particular to a chain-type automatic feeding machine. Background Art

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

[0003] Taking the heat pack products mainly produced by the applicant as an example, the heat pack is an external compress with self-heating properties, which promotes local blood circulation in the human body by the principle of hot compress. The production process of the heat pack is as follows: the first step is the production of the heat pack, in which the heat agent is made into an independent heat pack through the heat pack production equipment, and the heat pack is transported by a horizontally arranged conveyor belt connected to the discharge port of the heat pack production equipment; the second step is the production of the finished heat pack, in which the independent heat pack is conveyed to the equipment for producing the finished heat pack for processing; finally, the complete independently packaged heat pack product is output through the automatic material placement equipment connected to the back of the equipment for producing the finished heat pack.

[0004] Since the height of the heating pack production equipment is relatively low, the height of the conveyor belt connected to the back of the equipment must also be lower than the equipment for producing the finished heating packs, thus forming a certain height difference, which requires high-altitude feeding. The existing technology generally uses bucket conveyors or screw conveyors to carry out high-altitude feeding from low to high, but since the outer surface of the heating pack is generally made of light materials such as non-woven fabrics and breathable films, if a screw conveyor is used, the high-speed rotating spiral blades in the screw conveyor are easy to scratch or contaminate the outer surface of the heating pack. If a bucket conveyor is used, the edge of the hopper is also easy to scratch the surface of the heating pack in the process of scooping up the heating pack. Therefore, there is an urgent need for an automatic feeding machine for transferring fragile materials such as heating packs to ensure that the feeding process will not cause damage to the outer surface of the material. Utility Model Content

[0005] The utility model aims to provide a chain-type automatic feeding machine, which can solve the technical problem that the surface of materials is easily damaged during the feeding process.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A chain-type automatic loader comprises a frame and a lifting mechanism installed on the frame, the lifting mechanism comprises a chain, a silo and a sliding channel installed on the side end of the frame; the silo comprises a panel, a slide plate fixed at the bottom of the panel, and a magnetic baffle hinged to the slide plate, the slide plate is arranged at an angle, the panel and the chain are detachably connected, and a magnet is fixedly arranged on a side of the panel close to the magnetic baffle; an upper wedge block for opening the magnetic baffle is fixedly arranged on the top of the frame, the bottom surface of the upper wedge block is an inclined surface inclined toward a side close to the silo, and the bottom edge of the upper wedge block corresponds to the magnet, and a lower wedge block for closing the magnetic baffle is fixedly arranged on the bottom of the frame, the top surface of the lower wedge block is an inclined surface inclined toward a side away from the silo, and the top edge of the lower wedge block corresponds to the left 1 / 2 position of the magnetic baffle.

[0008] Beneficial effects:

[0009] When in use, the silo is first in the lowest position, and the material is transported from the front processing equipment to the silo through the conveyor belt. At this time, the silo is in a closed state, that is, the magnetic baffle is magnetically fixed to the magnet on the enclosure. After the material in the silo is filled, a chain-type lifting mechanism is used to lift the silo upward. An upper wedge block is fixed on the top of the frame, and the bottom surface of the upper wedge block is an inclined surface inclined toward the side close to the silo. When the silo is lifted to the point where the top surface of the magnetic baffle contacts the bottom surface of the upper wedge block, the upper wedge block will give the magnetic baffle a rightward thrust, causing the magnetic baffle to gradually move away from the magnet until it is fully opened. At this time, the silo is in an open state. Since the slide plate is inclined, the material loaded in the silo will fall along the slide plate into the sliding channel, thereby completing the transfer and loading of materials from low to high places without causing damage to the surface of the material.

[0010] It is worth mentioning that the bottom surface of the upper wedge block is an inclined surface inclined toward the side close to the silo. If the bottom surface of the upper wedge block is set to a horizontal plane, the problem that is easily caused is that the upper wedge block can only give the magnetic baffle a vertical downward thrust, and cannot help the magnetic baffle to break away from the magnetic fixation of the magnet. As for the bottom edge of the upper wedge block corresponding to the magnet, it is to ensure that the contact between the top surface of the magnetic baffle and the upper wedge block starts from the inclined surface on the upper wedge block. If the magnetic baffle is in contact with the bottom edge of the upper wedge block at the beginning, it can only give the upper wedge block a vertical downward thrust.

[0011] When the silo completes one loading, the lifting mechanism reverses to control the silo to descend, and a lower wedge block is fixed at the bottom of the frame, and the top edge of the lower wedge block corresponds to the left 1 / 2 position of the magnetic baffle. When the silo descends to the point where the bottom surface of the magnetic baffle contacts the top edge of the lower wedge block, as the silo continues to descend, the lower wedge block will give the magnetic baffle an upward thrust until the magnetic baffle is re-magnetically fixed to the magnet. At this time, the silo is reset to a closed state to prepare for the next loading.

[0012] It is worth mentioning that the top edge of the lower wedge block corresponds to the left 1 / 2 position of the magnetic baffle. After experiments by the utility model inventors, when the top edge of the lower wedge block corresponds to a position further to the left of the upper magnetic baffle, since the contact position between the top edge of the lower wedge block and the magnetic baffle is closer to the hinge between the magnetic baffle and the skateboard, according to the principle of lever, the magnetic baffle will give the lower wedge block a greater friction force. The top edge of the lower wedge block is severely worn after a period of use, and it is easy for the lower wedge block to fail to push the magnetic baffle, because the closer to the hinge, the greater the thrust that the lower wedge block needs to give to the magnetic baffle to completely push the magnetic baffle, and when the top edge of the lower wedge block corresponds to a position further to the right of the upper magnetic baffle, the magnetic baffle cannot get close to a position where it can generate magnetic field attraction with the magnet, so that the silo cannot be reset to a closed state.

[0013] Further, as an improvement, one end of the sliding channel close to the silo is a positioning end, and during the descent of the silo, the positioning end can come into hard contact with the magnetic baffle.

[0014] Beneficial effect: When the silo is in an open state, that is, when the magnetic baffle is unfolded, if there is a gap between the magnetic baffle and the sliding channel, the problem that may easily arise is that the material in the silo may easily slip away from the gap. During the descent of the silo, the positioning end can make hard contact with the magnetic baffle, thereby ensuring that the sliding of the material is continuous.

[0015] Furthermore, as an improvement, the lifting mechanism also includes a U-shaped connecting plate, the connecting plate includes an integrally formed bottom plate and side plates on both sides, the bottom plate is detachably connected to a side of the enclosure close to the chain, and the side plate is detachably connected to the chain.

[0016] Beneficial effect: The enclosure and the chain can be quickly connected together through the U-shaped connecting plate, so that the silo can be raised and lowered with the help of the lifting mechanism. As for the detachable connection, it is convenient for the staff to quickly install and disassemble the silo.

[0017] Further, as an improvement, the chain includes a driving chain and a driven chain, and the lifting mechanism also includes 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 driving wheel and the driven wheel are driven by the motor and the transmission chain, so that the driving chain and the driven chain can drive the silo to rise and fall, which is an important structure to ensure the operation of the lifting mechanism.

[0019] Further, as an improvement, the lifting mechanism includes a steel cable fixed to the frame and a sliding member sleeved on the steel cable, and a fixing plate is arranged on the top of the enclosure, and the fixing plate is detachably connected to the sliding member.

[0020] Beneficial effect: The sliding member can move in the vertical direction under the restriction of the steel cable, which is beneficial to ensure that the running track of the silo does not deviate from the direction and mainly plays a guiding role.

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

[0022] Beneficial effect: The controller with timing module controls the final lifting height of the silo, which is an important control element to ensure that the silo reaches the correct position smoothly.

[0023] Furthermore, as an improvement, a set of fixing frames are disposed transversely on the sides of the frame, a feeding trough which passes through from top to bottom is overlapped on the fixing frames, and the sliding channel is overlapped with the top of the feeding trough.

[0024] Beneficial effect: Under the feed chute is another set of equipment for processing materials. The feed chute is overlapped on the fixed frame on the side of the frame, which is conducive to the staff to achieve rapid installation and disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

A square outlet is opened on the enclosure 31 on the side close to the sliding channel 4, and two opposite magnets 34 are fixed above the outlet. The magnet 34 is a T-shaped structure, the magnetic end of the magnet 34 is disc-shaped, and the non-magnetic end of the magnet 34 is cylindrical. The non-magnetic end of the magnet 34 is made of metal and is integrally formed with the magnetic end. The non-magnetic end of the magnet 34 is welded to the enclosure 31, and the slide plate 32 is tilted downward. In this embodiment, the angle formed by the slide plate 32 and the horizontal plane is 40°. The magnetic baffle 33 is a metal plate that can be magnetically fixed to the magnetic end of the magnet 34. When the magnetic baffle 33 is fully unfolded, the angle between the magnetic baffle 33 and the horizontal plane is 35°, which can provide a certain buffer for the sliding of the material.

[0036] like Figure 4As shown, the lifting mechanism 2 includes a chain (i.e., a driving chain 21 and a driven chain 22), a driving wheel 211, a driven wheel 221, a motor 23, a driving wheel 24 coaxially connected to the output end of the motor 23, a transmission wheel 25 coaxially connected to the driving wheel 211, a transmission chain is installed between the transmission wheel 25 and the driving wheel 24, a transmission shaft is coaxially installed between the driving wheel 211 and the driven wheel 221, a U-shaped connecting plate 26 is installed on the driving chain 21 and the driven chain 22, and the connecting plate 26 includes an integrally formed bottom plate and side plates on both sides, pin holes are provided on the side plates on both sides, and the driving chain 21 and the driven chain 2 2 are provided with pins corresponding to the pin holes, so as to realize the detachable connection between the side plate and the chain, and the bottom plate on the connecting plate 26 is detachably connected to the side of the enclosure plate 31 close to the chain by bolts. The lifting mechanism 2 also includes a vertically arranged steel cable 27 fixed to the frame 1 by bolts and a sliding member 271 sleeved on the steel cable 27, the sliding member 271 is T-shaped, and an inverted L-shaped fixing plate 272 is set on the top of the enclosure plate 31, and the fixing plate 272 is detachably connected to the sliding member 271 by bolts. The detachable connection makes it more convenient for the staff to install or disassemble the silo 3.

[0037] The lifting mechanism 2 further includes a control cabinet 28 mounted on the frame 1 . A controller with a timing module is installed in the control cabinet 28 . The controller 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 on the top of the frame 1, and the bottom surface 51 of the upper wedge block 5 is an inclined surface inclined toward the side close to the silo 3, and the bottom edge 52 of the upper wedge block 5 corresponds to the non-magnetic end of the magnet 34. A lower wedge block 6 for closing the magnetic baffle 33 is welded on the bottom of the frame 1, and the top surface 61 of the lower wedge block 6 is an inclined surface inclined toward the side away from the silo 3, and the top edge 62 of the lower wedge block 6 corresponds to the left 1 / 2 position of the magnetic baffle 33.

[0039] The sliding channel 4 is a box with closed sides and bottom surface 51 and open top surface 61. The end of the sliding channel 4 close to the silo 3 is the positioning end 41. During the falling process of the silo 3, the positioning end 41 can make hard contact with the magnetic baffle 33. For example, in the present embodiment, when the silo 3 is in a closed state, the distance from the magnetic baffle 33 to the positioning end 41 is 20 cm. When the magnetic baffle 33 is fully expanded, the angle between the magnetic baffle 33 and the horizontal plane is 35°. When the length of the magnetic baffle 33 is greater than 25 cm, the fully expanded magnetic baffle 33 can make hard contact with the positioning end 41 when falling.

[0040] A set of fixing frames 7 parallel to the horizontal plane is laterally arranged on the side of the frame 1, and a feeding trough 8 is overlapped on the fixing frames 7 and runs through from top to bottom. The positioning end 41 of the sliding channel 4 is hinged to the frame 1, and the other end of the sliding channel 4 is overlapped with the top of the feeding trough 8.

[0041] Application of a chain automatic feeding machine in the production process of warm packs:

[0042] When in use, the silo 3 is first in the lowest position of the frame 1, and the independent heating pack is transferred to the silo 3 by the heating pack production equipment through the conveyor belt connected to the back. At this time, the silo 3 is in a closed state, that is, the magnetic baffle 33 is magnetically fixed to the magnet 34 on the enclosure 31. When the silo 3 is filled with the heating pack (the timing module in the controller has experienced 5s at this time), the chain-type lifting mechanism 2 is used to lift the silo 3 upward. Specifically, the motor 23 drives the coaxially arranged driving wheel 24 to rotate far, and then drives the driving wheel 211 and the driven wheel 221 to operate through the transmission chain. Since the silo 3 and the chain are connected together, the silo 3 can be lifted and lowered under the drive of the motor 23. An upper wedge block 5 is fixed on the top of the frame 1, and the bottom surface 51 of the upper wedge block 5 is inclined toward the side close to the silo 3. Inclined surface, when the silo 3 is lifted to the point where the top surface 61 of the magnetic baffle 33 contacts the bottom surface 51 of the upper wedge block 5, the upper wedge block 5 will give the magnetic baffle 33 a horizontal rightward thrust Fx, causing the magnetic baffle 33 to gradually move away from the magnet 34 until it is fully opened. At this time, the silo 3 is in an open state, and the timing module in the controller experiences 10s, and the controller controls the motor 23 to stop running. Since the slide plate 32 is inclined, the heating pack loaded in the silo 3 will fall along the slide plate 32 into the sliding channel 4, and the heating pack will finally be put into the feed trough 8 of the equipment for producing the finished product of the warm treasure, thereby completing the transportation and loading of the heating pack from a low place to a high place, and at the same time will not cause damage to the surface of the heating pack. At this time, the timing module in the controller experiences 5s, and the controller controls the motor 23 to reverse to control the silo 3 to descend.

[0043] The process of the silo 3 descending is as follows: a lower wedge block 6 is welded at the bottom of the frame 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 silo 3 descends to the point where the bottom surface 51 of the magnetic baffle 33 contacts the top edge 62 of the lower wedge block 6, as the silo 3 continues to descend, the lower wedge block 6 will give the magnetic baffle 33 an upward thrust until the magnetic baffle 33 and the magnet 34 are magnetically fixed again. At this time, the silo 3 is reset to a closed state to prepare for the next loading.

[0044] Embodiment 2

[0045] The difference between this embodiment and the first embodiment is that, in combination with Figure 5 , Figure 6As shown, a cover plate 35 is hinged on the top of the enclosure 31 at the end where the magnet 34 is set. The function of the cover plate 35 is to seal the silo 3. The purpose of this arrangement is that the independent heating packs are transferred to the silo 3 by the heating pack production equipment through the conveyor belt connected to the back. The heating packs cannot be stacked regularly in the silo 3. Even if the heating packs can just fill the silo 3 after 5s of the timing module in the controller in Example 1, the top layer of heating packs will inevitably be exposed at the edge of the enclosure 31. The exposed part of the heating pack may come into contact with the active chain 21 or the driven chain 22 during the rising process of the silo 3, and there is a possibility of damaging part of the surface of the heating pack.

[0046] At the bottom of rack 1 Figure 6 As shown, two baffle plates 11 parallel to the horizontal plane are welded on the left side. When the silo 3 is at the lowest position of the frame 1, the two baffle plates can lift the two sides of the cover plate 35 to form an angle of 45° with the horizontal plane, so that the heating packs can be smoothly transferred to the silo 3. When the silo 3 has been filled with heating packs and the silo 3 needs to be lifted, the cover plate 35 will automatically close without the limit of the baffle plates 11, thereby protecting the heating packs on the top layer of the silo 3.

[0047] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
