Description

Technical Field

[0001] The utility model relates to a plate feeding device of a tongue depressor packaging machine. Background Art

[0002] A tongue depressor packaging machine needs to provide tongue depressors to the device for sealing and packaging. During the packaging operation, the plate feeding device needs to stably and efficiently supply the tongue depressors to ensure efficient and stable sealing and packaging. In addition, during high-speed operation, the tongue depressors in the plate feeding device are extremely easy to be used up, and it is often necessary to manually supplement the tongue depressors into the plate feeding device. For example, in the plate feeding device of the tongue depressor packaging machine of CN219635585U, the inventory of tongue depressors in the vertical bin is small, the height is relatively high, and it is time-consuming and laborious to frequently supplement, resulting in low efficiency. In addition, during high-speed operation, material jamming is likely to occur, and the tongue depressors are jammed, resulting in a shutdown of the plate feeding due to a fault. Summary of the Utility Model

[0003] In view of the technical problems existing in the background art, the technical problem solved by the utility model aims to provide a plate feeding device of a pressing plate packaging machine with a relatively large material storage capacity, relatively convenient supplementary feeding, and no need for frequent supplementary feeding.

[0007] Further optimization: the tongue depressor transfer piece includes a transfer unit plate, and the transfer unit plate is further provided with a pushing boss and a tongue depressor bearing surface. The pushing boss is located at the end of the transfer unit plate, and the tongue depressor bearing surface is located on the forward conveying side of the pushing boss.

[0008] It can also be optimized so that the protruding height of the pushing boss matches that of a tongue depressor with a certain thickness; a redundant cleaning brush for the tongue depressor is also provided on the front side of the transfer output area of the tongue depressor.

[0010] For example, a partition plate is provided in the storage bin. The partition plate divides the storage bin into a front bin and a rear bin. A swing bottom support plate is arranged below the partition plate. A swing support shaft is located at the bottom of the front bin, and a lower driving wheel is located at the bottom of the rear bin. The swing support shaft is relatively located below the lower driving wheel.

[0012] For additional optimization, the lower driving wheel is drivingly connected to a swing driving cam. A driving cooperation part is provided on the swing bottom support plate, and the driving cooperation part corresponds to and is in driving cooperation with the swing driving cam.

[0013] For example, the driving cooperation part includes a roller and is located at the rear end of the swing bottom support plate; the driving cooperation part abuts against the swing driving cam. The lower driving wheel is arranged on a lower transmission shaft, the swing driving cam is connected to the lower transmission shaft, an upper driving wheel is arranged on an upper transmission shaft, the upper transmission shaft is drivingly connected to the brush driving shaft, and the redundant cleaning brush for the tongue depressor is arranged on the brush driving shaft and is configured on the front side of the plate feeding and transferring component.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the implementation manners of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0024] Referring to the attached drawings, in the embodiment of this implementation manner, the plate feeding device of the tongue depressor packaging machine includes a material storage bin 1 that can be used to store tongue depressors. The material storage bin 1 includes a front baffle 2, a left baffle 3, a right baffle 4, a swing bottom support plate 5, and a plate feeding transfer component 6, which cooperate to enclose the material storage bin 1. The upper part of the material storage bin 1 is open or equipped with an additional lid to facilitate online connection, even online connection with the tongue depressor manufacturing equipment or an automatic feeding device.

[0025] Among them, the front part of the swing bottom support plate 5 is connected to the swing support shaft 7. The axis of the swing support shaft 7 is horizontally arranged left and right, that is, the swing bottom support plate 5 can not only cooperate to support the tongue depressors placed in the material storage bin 1, but also the swing bottom support plate 5 can be swing-rotated and supported by the swing support shaft 7. The swing bottom support plate 5 can swing up and down around the swing support shaft 7, so that the tongue depressors in the material storage bin 1 can be moved, so as to facilitate the sorting and output of the tongue depressors for plate feeding.

[0026] Among them, the plate feeding transfer component 6 is arranged at the rear of the material storage bin 1, and the material feeding and moving component cooperates to output the tongue depressors in the material storage bin 1 for plate feeding.

[0027] Among them, the plate feeding transfer component 6 includes a tongue depressor transfer piece 8 and a surrounding transmission piece 9 (such as a chain, etc.) connected end to end. The tongue depressor transfer piece 8 is arranged on the surrounding transmission piece 9; the upper part of the surrounding transmission piece 9 is wound and connected to the upper transmission wheel, and the lower part of the surrounding transmission piece 9 is wound and connected to the lower transmission wheel 11. The lower transmission wheel 11 is relatively located in front of the upper transmission wheel, forming an inclined transfer structure with a slope; the tongue depressor transfer pieces 8 are evenly distributed on the surrounding transmission piece 9. When the surrounding transmission piece 9 winds around the upper transmission wheel and the lower transmission wheel 11, the tongue depressor transfer piece 8 can transfer and output the tongue depressors from the middle and rear parts of the material storage bin 1 from bottom to top for plate feeding.

[0028] Among them, the rear end of the swing bottom support plate 5 has an avoidance opening 12, and the plate feeding transfer component 6 is arranged to pass through the avoidance opening 12. The swing bottom support plate 5 can smoothly move the tongue depressors in the material storage bin 1 by swinging, so that the plate feeding transfer component 6 can smoothly output the tongue depressors, and it can also reduce the occurrence of material jamming.

[0029] In the plate feeding device of this tongue depressor packaging machine, the tongue depressors do not need to be vertically stacked in the material storage bin 1. The storage capacity of the material storage bin 1 can be relatively large, and there is no need to frequently replenish the tongue depressors in the material storage bin 1, nor is there a need for vertical stacking. It is more convenient to replenish the tongue depressors (supplemental feeding) into the material storage bin 1; the swing bottom support plate 5 can move the tongue depressors in the material storage bin 1 so that they can be smoothly transferred and output by the plate feeding transfer component 6 for plate feeding.

[0030] Based on the above embodiments respectively, the following optimizations or further explanations can be made.

[0031] For example, the front side of the surround transmission member 9 is the tongue depressor transfer and output area, and the tongue depressor transfer and output area is located between the upper transmission wheel and the lower transmission wheel 11, and the lower transmission wheel 11 is relatively located on the front side of the upper transmission wheel, so that the tongue depressor transfer and output area is an oblique transfer structure with a slope, and the front side of the surround transmission member 9 faces the material warehouse 1, so that the tongue depressor transfer member 8 can smoothly contact and cooperate with the tongue depressor in the material warehouse 1 for transfer during operation.

[0032] For another example, the tongue depressor transporting member 8 includes a transporting unit plate 13, which is also provided with a push boss (used to cooperate with the push of the tongue depressor to move), and a tongue depressor bearing surface 15 (used to cooperate with the carrying and pushing of the tongue depressor), the push boss is located at the end of the transporting unit plate 13, the tongue depressor bearing surface 15 is located on the conveying forward side of the push boss (i.e., in the conveying forward direction), and the lower transmission wheel 11 is relatively located at the front side of the upper transmission wheel, wherein the transporting unit plate 13 can smoothly carry and push the tongue depressor for transport and output. The tongue depressor bearing surface 15 matches the tongue depressor so as to stably support it. Usually, the protruding height of the pushing boss matches the thickness of a tongue depressor (no need to be completely consistent) to avoid pushing multiple tongue depressors; however, there may still be multiple (such as two) tongue depressors on a transfer unit plate 13, and the front side of the tongue depressor transfer output area is also equipped with a tongue depressor redundant cleaning brush 16, which can be used to brush off and clean the excess tongue depressors on the transfer unit plate 13 to avoid material jamming. For example, the tongue depressor redundant cleaning brush 16 adopts a brush roller, and the tongue depressor redundant cleaning brush 16 rotates and brushes downward to discharge materials, that is, the tongue depressor redundant cleaning brush 16 (such as a brush roller) removes the tongue depressor by rotating and brushing downward to discharge materials, and can discharge redundant (excess) tongue depressors into the material bin; wherein, the tongue depressor redundant cleaning brush 16 is transmission-connected to the brush drive shaft 17, and the tongue depressor redundant cleaning brush 16 is driven by the brush drive shaft 17 to rotate.

[0033] Further optimization, a partition plate 18 is provided in the material warehouse 1, and the partition plate 18 divides the material warehouse 1 into a front warehouse 19 and a rear warehouse 20, and a swinging bottom support plate 5 is arranged below the partition plate 18, and the swinging support shaft 7 is located at the bottom of the front warehouse 19, and the lower transmission wheel 11 is located at the bottom of the rear warehouse 20, and the swinging support shaft 7 is relatively located on the lower side of the lower transmission wheel 11, so that the swinging support shaft 7 is relatively (lower transmission wheel 11) in the front and higher position, and the swinging bottom support plate 5 continuously moves the tongue depressor during the swinging process, and can smoothly move the tongue depressor in the front warehouse 19 to the rear warehouse 20 gradually through the swinging, so that the material (tongue depressor) in the front warehouse 19 can be more, and the material in the rear warehouse 20 is relatively less, and the tongue depressor in the rear warehouse 20 is easy to be stably output, and during the operation, the tongue depressor in the front warehouse 19 is continuously moved to the rear warehouse 20 through the swinging to replenish the tongue depressor.

[0034] The lower end of the material separator 18 is bent forward to form a material guide backward guide portion 21. For example, the lower end of the material separator 18 is bent forward to form a material guide backward guide portion 21. The material guide backward guide portion 21 can be used for guiding, and cooperates to guide the tongue depressor into the rear bin 20 during the swinging operation of the swinging bottom support plate 5 (up and down), ensuring that there is a tongue depressor in the rear bin 20. Among them, the material separator 18 above the material guide backward guide portion 21 is vertically arranged for easy installation. In addition, the material warehouse 1 also includes a fixed bottom support plate 22, which is located on the front side of the swinging bottom support plate 5. The fixed bottom support plate 22 is obliquely arranged with the front higher and the rear lower, so that the tongue depressor can naturally slide to the swinging bottom support plate 5 area, and then the swinging bottom support plate 5 moves the tongue depressor by swinging.

[0035] The swinging operation of the swinging bottom support plate 5 can be configured to be driven by power alone, or it can be operated in a linkage manner, such as in linkage with the surrounding transmission member 9. For example, the lower transmission wheel 11 is connected to the swing driving cam 23, and the swinging bottom support plate 5 is provided with a transmission matching part 24, and the transmission matching part 24 corresponds to the swing driving cam 23 for transmission matching, and the swing driving cam 23 and the transmission matching part 24 cooperate to drive the swinging bottom support plate 5 to swing up and down around the swing support shaft 7; wherein the swinging of the swinging bottom support plate 5 and the operation of the surrounding transmission member 9 are linked, the structure is compact, the matching degree is good, and the power is shared. For example, the transmission matching part 24 includes a roller, and the transmission matching part 24 is located at the rear end of the swinging bottom support plate 5; the transmission matching part 24 is arranged on the swing driving cam 23, and the swing driving cam 23 supports the lower transmission wheel 11 to rise and fall, the lower transmission wheel 11 is arranged on the lower transmission shaft 25, and the swing driving cam 23 is connected to the lower transmission shaft 25, and the lower transmission wheel 11 synchronously drives the lower transmission wheel 11 and the swing driving cam 23 to rotate together. In addition, the brush drive shaft 17 can be configured with independent power or can be linked; for example, the upper transmission wheel is arranged on the upper transmission shaft 26, and the upper transmission shaft 26 is connected to the brush drive shaft 17 in transmission. The brush drive shaft 17 is provided with a tongue depressor redundant cleaning brush 16, and the tongue depressor redundant cleaning brush 16 is arranged on the front side of the feeding plate transfer component 6.

[0036] For a more reasonable transmission structure, the upper transmission wheel is arranged on the upper transmission shaft 26. A front transmission wheel 27 is also provided on the upper transmission shaft 26. A rear transmission shaft 28 is provided behind the upper transmission shaft 26. A rear transmission wheel 29 is drivingly connected to the rear transmission shaft 28. The front transmission wheel 27 and the rear transmission wheel 29 are arranged corresponding to each other front and rear (such as horizontally corresponding). A conveying chain 30 is wound between the front transmission wheel 27 and the rear transmission wheel 29. Pushing heads 31 (such as pushing claws) are uniformly arranged on the conveying chain 30. The pushing heads 31 are used to cooperate with the pushing of the tongue pressing plate to move forward; the tongue pressing plate transfer member 8 is in feeding connection and cooperation with the pushing heads 31. After the tongue pressing plate transfer member moves the tongue pressing plate of the magazine 1 out with the surrounding transmission member 9, the pushing heads 31 cooperate to connect and feed. Even more, the rear transmission shaft 28 and the upper transmission shaft 26 can be directly drivingly connected by the conveying chain 30, which can not only realize the material conveying but also conduct the driving connection; the lower transmission wheel 11 is arranged on the lower transmission shaft 25. The upper transmission shaft 26 and the lower transmission shaft 25 are drivingly connected by the surrounding transmission member 9; the surrounding transmission member 9 adopts a chain, which can also cooperate to realize the material conveying and the driving connection. The output end of the plate feeding transfer component 6, the input end of the conveying chain 30, and the connection between the plate feeding transfer component 6 and the conveying chain 30 are equipped with a material pressing and limiting and guiding component 32 (such as a guiding plate). The material pressing and limiting and guiding component 32 can press and limit the tongue pressing plate when the tongue pressing plate is transferred and output by the plate feeding transfer component 6 (such as the tongue pressing plate transfer member 8) and when the pushing heads 31 on the conveying chain 30 cooperate to connect and convey, so as to avoid the tongue pressing plate from flying out and shifting, and ensure that the tongue pressing plate is transferred from the plate feeding transfer component 6 to the conveying chain 30 for conveying.
