Description

Technical Field

[0001] This utility model relates to the technical field of chain-type paper bowl processing device, and in particular to a paper transfer mechanism. Background Technology

[0002] Existing chain-type paper pots for tobacco seedling cultivation require multiple paper sheets to be glued to a continuous paper strip at intervals during production to form the seedling holes. Most chain-type paper pot production equipment on the market currently uses a robotic arm with a suction nozzle to directly pick up and transfer the paper sheets. Since the area of ​​the suction nozzle is usually smaller than the area of ​​the paper sheet, the paper sheet wrinkles around the nozzle when it is picked up, causing the entire paper sheet to shrink towards the nozzle. This makes it difficult to glue the paper sheet flat onto the paper strip, affecting the formation of the seedling holes. Furthermore, because the paper sheet is relatively thin, the adhesive used to glue it may seep through, sticking the paper sheet to the surface around the suction nozzle, affecting the paper sheet attachment. Utility Model Content

[0003] The purpose of this invention is to provide a paper transfer mechanism that can keep the paper flat while preventing it from sticking to the substrate, thus ensuring that the paper can be released stably.

[0004] To achieve this objective, the present invention adopts the following technical solution: a paper transfer mechanism, comprising a transmission device, a storage device, and a transfer device. The transmission device is used to transmit the paper tape to be processed along a first direction. The storage device is located on one side of the transmission device and has a storage cavity with a top opening for storing the paper pieces to be pasted. The transfer device includes a drive module and a suction module. The suction module is located above the storage device and includes a substrate and a suction nozzle. The suction nozzle is installed on the side of the substrate facing the storage cavity and is connected to an external negative pressure air source through a connecting pipe. The substrate is provided with a brush that covers the wall surface of the substrate where the suction nozzle is located. Along the thickness direction of the substrate, the height of the brush is equal to the height of the suction nozzle. The output end of the drive module is connected to the suction module to drive the suction module to move the paper pieces from the storage cavity to the paper tape.

[0005] Preferably, the suction nozzle is provided in multiple forms, and the multiple suction nozzles are arranged in a matrix.

[0006] Preferably, the suction nozzle is provided in multiple locations, and the multiple suction nozzles are arranged at intervals along the diagonal direction of the substrate.

[0007] Preferably, the end of the suction nozzle is provided with a silicone sleeve, which is flared in shape.

[0008] Preferably, the suction module further includes a support plate, which is arranged parallel to the substrate. The support plate is connected to a plurality of connecting columns that can slide relative to the support plate in a vertical direction. The ends of the connecting columns are fixed to the substrate. The connecting columns are fitted with springs, which are pressed against the support plate and the substrate. The support plate is connected to the output end of the drive module.

[0009] Preferably, the substrate has a reinforcing portion that protrudes from the side of the substrate facing the support plate, and the connecting post is connected to the reinforcing portion.

[0010] Preferably, the reinforcing part is provided with an air passage that extends through the substrate, and at least a portion of the suction nozzle is connected to the connecting tube through the air passage.

[0011] Preferably, the support plate is provided with a through hole for the connecting pipe to pass through.

[0012] Preferably, the storage device includes a storage frame and a lifting member, the storage frame forming the storage cavity, and the lifting member being connected to the bottom surface of the storage frame to drive the bottom surface of the storage frame to move vertically.

[0013] Preferably, the storage device further includes an infrared sensor, the detection end of which is disposed facing the top of the storage cavity.

[0014] The beneficial effects of this utility model are as follows: When the paper transfer mechanism is working, the drive module of the transfer device drives the suction module to move back and forth between the storage device and the transmission device, thereby transferring the paper pieces in the storage cavity to the paper tape. By setting a brush at the same height as the suction nozzle, on the one hand, the brush covers the end face of the substrate around the suction nozzle. When the suction nozzle picks up the paper pieces, the brush can support the paper pieces, keep the paper pieces flat, and ensure the stability and integrity of the paper pieces being pasted; on the other hand, when the drive module drives the suction module to move onto the paper tape to paste the paper pieces, the suction nozzle releases the paper pieces. If the glue penetrates the paper pieces, the contact area between the brush tip and the glue is small, and a stable adhesive force cannot be generated, which can prevent the paper pieces from sticking to the substrate and ensure that the paper pieces can be released stably. At the same time, the brush can slightly rebound to separate the paper pieces from the suction nozzle, realizing the rapid release of the paper pieces. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0026] Reference Figures 1 to 4 As shown, a paper transfer mechanism provided according to an embodiment of this application includes a transmission device, a storage device 100 and a transfer device 200. The transmission device is used to transmit the paper tape to be processed along a first direction. The storage device 100 is located on one side of the transmission device and has a storage cavity with a top opening for storing paper pieces to be pasted.

[0027] The transfer device 200 includes a drive module 210 and a suction module 220. The drive module 210 includes a first lead screw drive, a second lead screw drive, and a third lead screw drive. The first lead screw drive is provided with a first slider that can reciprocate along a first direction. The second lead screw drive is mounted on the first slider and is provided with a second slider that can reciprocate along a second direction. The third lead screw drive is mounted on the second slider and is provided with a third slider that can reciprocate along a vertical direction. The suction module 220 is mounted on the third slider. The suction module 220 is located above the storage device 100. The suction module 220 includes a substrate 221 and a suction nozzle 222. The suction nozzle 222 is installed on the side of the substrate 221 facing the storage cavity. The suction nozzle 222 is connected to an external negative pressure air source through a connecting pipe 224. The substrate 221 is provided with a brush 2211. The brush 2211 covers the wall surface of the substrate 221 where the suction nozzle 222 is located. Along the thickness direction of the substrate 221, the height of the brush 2211 is equal to the height of the suction nozzle 222. The output end of the drive module 210 is connected to the suction module 220 to drive the suction module 220 to move the paper sheet from the storage cavity to the paper tape. Optionally, a gluing device is provided between the storage device 100 and the transmission device, and a motor-driven rotating rod is provided between the third slider and the suction module 220. One end of the rotating rod is rotatably connected to the third slider, and the other end is fixedly connected to the suction module 220. The drive module 210 and the rotating rod cooperate to drive the suction module 220 to move the paper sheet to the gluing device. The gluing device is used to spray glue onto the paper sheet. The drive module 210 and the rotating rod can also drive the glued paper sheet to stick to one side of the paper tape, or alternately stick multiple paper sheets to both sides of the paper tape.

[0028] Understandably, when the paper transfer mechanism is working, the drive module 210 of the transfer device 200 drives the suction module 220 to move back and forth between the storage device 100, the glue applicator and the transfer device, thereby transferring and pasting the paper pieces in the storage cavity onto the paper tape. By setting a brush 2211 at the same height as the suction nozzle 222, on the one hand, the brush 2211 covers the end face of the substrate 221 around the suction nozzle 222. When the suction nozzle 222 picks up the paper, the brush 2211 can support the paper, keep the paper flat, and ensure the stability and integrity of the paper pasting. On the other hand, when the drive module 210 drives the suction module 220 to move onto the paper tape to paste the paper, the suction nozzle 222 releases the paper. If the glue penetrates the paper, the contact area between the end of the brush 2211 and the glue is small, and a stable adhesive force cannot be generated. This can prevent the paper from pasting onto the substrate 221 and ensure that the paper can be released stably. At the same time, the brush 2211 can slightly rebound to separate the paper from the suction nozzle 222, realizing the rapid release of the paper.

[0029] Furthermore, the end of the suction nozzle 222 is provided with a silicone sleeve 2221, which is flared. In other words, the inner diameter of the silicone sleeve 2221 gradually increases in the height direction of the substrate 221 in the direction away from the substrate 221.

[0030] By setting up the silicone sleeve 2221, the flared silicone sleeve 2221 can increase the contact area between the suction nozzle 222 and the paper, improve the adsorption force, and the flexible silicone material can fit the paper surface to ensure the flatness of the paper.

[0031] Reference Figure 3 As shown (features related to the brush 2211 have been omitted for ease of viewing), it can be understood that there are multiple suction nozzles 222 arranged in a matrix. Optionally, the suction nozzles 222 can be arranged in a 2×2 configuration at the four corners of the substrate 221, in a 2×1 configuration on both sides of the substrate 221, or in a 3×2 configuration on the substrate 221. The number and arrangement of the suction nozzles 222 are not specifically limited here, as long as they can stably pick up paper sheets.

[0032] Arranging multiple suction nozzles 222 in a matrix can effectively increase the contact area between the suction nozzles 222 and the paper, ensuring the adsorption force of the suction module 220. At the same time, the matrix arrangement of the suction nozzles 222 can also provide a certain plane support to ensure the flatness of the paper.

[0033] Reference Figure 4As shown (features related to the brush 2211 have been omitted for ease of viewing), it can be understood that multiple suction nozzles 222 are provided, and the multiple suction nozzles 222 are arranged at intervals along the diagonal direction of the substrate 221. Optionally, there can be two suction nozzles 222, with the two suction nozzles 222 respectively located at two opposite corners of the substrate 221; there can also be three suction nozzles 222, with the three suction nozzles 222 linearly arranged on the substrate 221 along the diagonal direction. The number of suction nozzles 222 is not specifically limited here, as long as it can stably pick up paper sheets.

[0034] By arranging multiple suction nozzles 222 diagonally, the number of suction nozzles 222 can be reduced while ensuring that the suction module 220 can pick up paper, thereby reducing the manufacturing cost of the suction module 220.

[0035] Reference Figure 2 As shown, the suction module 220 also includes a support plate 223, which is arranged parallel to the base plate 221. The support plate 223 is connected to multiple connecting posts 2231 that can slide vertically relative to it. Specifically, two or four connecting posts 2231 can be symmetrically arranged, which will not be elaborated here. The ends of the connecting posts 2231 are fixedly connected to the base plate 221. Springs 2232 are sleeved on the connecting posts 2231, and these springs abut against the support plate 223 and the base plate 221. The support plate 223 is connected to the output end of the drive module 210.

[0036] By setting the connecting post 2231 and the spring 2232, the substrate 221 can move toward the support plate 223 or return to its original position away from the support plate 223. When the drive module 210 drives the suction module 220 to paste the paper, the spring 2232 can absorb the impact force of the substrate 221, which plays a buffering role and prevents the paper tape from being crushed.

[0037] Furthermore, the substrate 221 is provided with a reinforcing part 2212, which protrudes from the side of the substrate 221 facing the support plate 223, and the connecting post 2231 is connected to the reinforcing part 2212.

[0038] By providing the reinforcing part 2212, the strength structure of the connection between the connecting post 2231 and the base plate 221 can be enhanced, and the installation or removal of the connecting post 2231 can be facilitated.

[0039] Furthermore, the reinforcing part 2212 is provided with an air passage that extends through the substrate 221. The connecting pipe 224 is sealed to the air passage opening of the connecting part through a sealing head 2241. At least some of the suction nozzles 222 are connected to the connecting pipe 224 through the air passage. Specifically, when the suction nozzles 222 are arranged in a matrix, the suction nozzles 222 located on both sides of the substrate 221 along the length of the substrate 221 are connected to the air passage; when the suction nozzles 222 are arranged diagonally, the suction nozzles 222 located at opposite corners of the substrate 221 are connected to the air passage. Optionally, the air passage can be a branch air passage with one inlet and multiple outlets. In this case, one connecting pipe 224 can generate negative pressure for multiple suction nozzles 222 connected to the same air passage. The air passage can also be a straight passage with one inlet and one outlet. In this case, the connecting pipe 224 corresponds one-to-one with the suction nozzle 222.

[0040] By setting up an air passage that is sealed to the connecting tube 224, the sealing performance between the nozzle 222 and the connecting tube 224 can be effectively improved, while also facilitating the installation or removal of the connecting tube 224.

[0041] Reference Figure 1 and Figure 2 As shown, it can be understood that the support plate 223 is provided with a through hole 2233 for the connecting pipe 224 to pass through.

[0042] When installing the connecting pipe 224, the user can first pass the connecting pipe 224 through the through hole 2233, then connect the sealing head 2241, and finally install the sealing head 2241 onto the reinforcing part 2212. By setting the through hole 2233, the wiring layout of the connecting pipe 224 can be optimized, avoiding the accumulation of the connecting pipe 224 in the gap between the base plate 221 and the support plate 223, and improving the ease of installation and removal of the connecting pipe 224.

[0043] Reference Figure 1 As shown, the storage device 100 includes a storage frame 110 and a lifting member 120, with the storage frame 110 forming a storage cavity. Specifically, the storage frame 110 includes a plurality of limiting posts 111 and a base plate 112. The plurality of limiting posts 111 are arranged circumferentially around the base plate 112, and the storage cavity is formed between the plurality of limiting posts 111 and the base plate 112. The lifting member 120 is connected to the bottom surface of the storage frame 110 (i.e., the base plate 112) to drive the bottom surface of the storage frame 110 to move vertically. Optionally, the lifting member 120 may be a vertically arranged ball screw slider structure or a vertically arranged push rod structure, etc., which will not be described in detail here.

[0044] By setting up the lifting component 120, when the suction module 220 moves above the storage cavity, the lifting component 120 drives the bottom surface of the storage frame 110 to rise, thereby reducing the gap between the paper and the suction nozzle 222, making it easier for the suction nozzle 222 to pick up the paper and improving the working efficiency of the transplanting device.

[0045] Furthermore, the storage device 100 also includes an infrared sensor 130, the detection end of which is disposed facing the top of the storage cavity, and the infrared sensor 130 is communicatively connected to the controller of the lifting member 120.

[0046] By setting an infrared sensor 130, the infrared sensor 130 can detect whether the paper has moved to the top of the storage cavity, thereby controlling the lifting component 120 to stop in time, avoiding the bottom surface of the storage frame 110 from rising too far and the paper from falling out of the storage frame 110, thus improving the structural rationality of the storage device 100.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
