Description

Technical Field

[0001] The invention relates to the technical field of chain-type paper bowl processing devices, and in particular to a paper sheet transfer mechanism. Background Art

[0002] Existing chain paper pots used for tobacco seedling cultivation require multiple paper sheets to be pasted onto a continuous paper strip at intervals during production to form a seedling hole structure. Most chain paper pot production devices currently on the market use a suction device consisting of a robotic arm and a suction nozzle to directly suck and transfer the paper sheets. Because the area of the suction nozzle is usually smaller than the area of the paper sheet, wrinkles will form around the nozzle when the nozzle sucks the paper sheet, causing the entire paper sheet to shrink toward the nozzle, making it difficult to stick the paper sheet flatly to the paper strip, affecting the formation of the seedling hole. In addition, due to the thin thickness of the paper sheet, the glue used to stick the paper sheet may also penetrate the paper sheet and stick the paper sheet to the flat surface around the nozzle, affecting the paper sheet installation. Summary of the Invention

[0003] The object of the present invention is to provide a paper sheet transfer mechanism that can keep the paper sheet flat and prevent the paper sheet from sticking to the substrate, thereby ensuring that the paper sheet can be released stably.

[0004] To achieve this object, the present invention adopts the following technical solutions: a paper sheet transfer mechanism, including 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, the storage device is provided with a storage cavity with a top opening, and the storage cavity is used to store the paper sheets to be pasted; the transfer device includes a driving module and a suction module, the suction module is located above the storage device, the suction module includes a substrate and a suction nozzle, the suction nozzle is installed on the side of the substrate facing the storage cavity, the suction nozzle is connected to an external negative pressure air source through a connecting pipe, the substrate is provided with a brush, the brush covers the wall surface of the substrate where the suction nozzle is located, and along the thickness direction of the substrate, the height of the brush is equal to the height of the suction nozzle, and the output end of the driving module is connected to the suction module to drive the suction module to move the paper sheet from the storage cavity to the paper tape.

[0005] Preferably, there are multiple suction nozzles, and the multiple suction nozzles are arranged in a matrix.

[0006] Preferably, a plurality of the suction nozzles are provided, and the plurality of suction nozzles are arranged at intervals along the diagonal direction of the substrate.

[0007] Preferably, a silicone sleeve is provided at the end of the nozzle, and the silicone sleeve is trumpet-shaped.

[0008] Preferably, the absorption module also includes a support plate, which is arranged parallel to the base plate, and 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 base plate, and the connecting column sleeve is provided with a spring, which is pressed between the support plate and the base plate, and the support plate is connected to the output end of the driving module.

[0009] Preferably, the base plate is provided with a reinforcing portion, the reinforcing portion protrudes from a side of the base plate facing the support plate, and the connecting column is connected to the reinforcing portion.

[0010] Preferably, the reinforcement portion is provided with an air channel, the air channel passes through the base plate, and at least part of the suction nozzle is connected to the connecting pipe through the air channel.

[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 is arranged to form the storage cavity, and the lifting member is connected to the bottom surface of the storage frame to drive the bottom surface of the storage frame to move in the vertical direction.

[0013] Preferably, the storage device further comprises an infrared sensor, and a detection end of the infrared sensor is arranged toward the top of the storage cavity.

[0014] The beneficial effects of the present invention are as follows: when the paper sheet transfer mechanism is working, the driving 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 sheet in the storage cavity to be pasted onto the paper tape. By setting a brush at the same height as the suction nozzle, on the one hand, the brush covers the end surface of the substrate around the suction nozzle. When the suction nozzle sucks the paper sheet, the brush can support the paper sheet, keep the paper sheet flat, and ensure the stability and integrity of the paper sheet pasting; on the other hand, when the driving module drives the suction module to move to the paper tape to paste the paper sheet, the suction nozzle releases the paper sheet. If the glue penetrates the paper sheet, the contact area between the brush end and the glue is small, and no stable adhesion can be generated, which can prevent the paper sheet from being pasted onto the substrate, ensuring that the paper sheet can be released stably. At the same time, the brush can slightly rebound to separate the paper sheet and the suction nozzle, thereby achieving rapid release of the paper sheet. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Reference Figures 1 to 4 As shown, a paper sheet transfer mechanism provided according to an embodiment of the present 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 the storage device 100 is provided with a storage cavity with a top opening, and the storage cavity is used to store paper sheets 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 screw drive, a second screw drive and a third screw drive. The first screw drive is provided with a first slider that can move back and forth in a first direction. The second screw drive is installed on the first slider. The second screw drive is provided with a second slider that can move back and forth in a second direction. The third screw drive is installed on the second slider. The third screw drive is provided with a third slider that can move back and forth in a vertical direction. The suction module 220 is installed 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 the external negative pressure air source through the connecting tube 224. The substrate 221 is provided with a brush 2211. The brush 2211 is covered with 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 driving module 210 is connected to the suction module 220 to drive the suction module 220 to move the paper 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 fixed to the suction module 220. The driving 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 on the paper sheet. The driving module 210 and the rotating rod can also drive the glued paper sheet to be pasted to one side of the paper tape, or alternately paste multiple paper sheets to both sides of the paper tape.

[0028] It is understandable that when the paper sheet transfer mechanism is working, the driving module 210 of the transfer device 200 drives the suction module 220 to move back and forth between the storage device 100, the gluing device and the transmission device, thereby transferring the paper sheets in the storage cavity to be pasted 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 surface of the substrate 221 around the suction nozzle 222. When the suction nozzle 222 sucks 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 driving module 210 drives the suction module 220 to move to 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 stable adhesion cannot be generated, which can prevent the paper from sticking to the substrate 221, ensuring that the paper can be released stably. At the same time, the brush 2211 can rebound slightly to separate the paper and the suction nozzle 222, thereby achieving rapid release of the paper.

[0029] Furthermore, a silicone sleeve 2221 is provided at the end of the nozzle 222 , and the silicone sleeve 2221 is in a bell-mouth shape. In other words, the inner diameter of the silicone sleeve 2221 gradually increases in the height direction of the substrate 221 and in the direction away from the substrate 221 .

[0030] By providing the silicone sleeve 2221, the bell-shaped silicone sleeve 2221 can increase the contact area between the suction nozzle 222 and the paper sheet, thereby improving the adsorption force. The flexible silicone material can adhere to the surface of the paper to ensure the flatness of the paper sheet.

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

[0033] Reference Figure 4As shown (for ease of illustration, features related to the brush 2211 have been omitted), it can be understood that there are multiple suction nozzles 222, 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, and the two suction nozzles 222 are respectively arranged at two diagonal positions of the substrate 221. There can also be three suction nozzles 222, and the three suction nozzles 222 are linearly arranged on the substrate 221 along the diagonal direction of the substrate 221. The number of suction nozzles 222 is not specifically limited, as long as they can stably suck paper sheets.

[0034] The plurality of suction nozzles 222 are arranged diagonally, and the number of the suction nozzles 222 is reduced while ensuring that the suction module 220 can suck paper pieces, thereby reducing the manufacturing cost of the suction module 220.

[0035] Reference Figure 2 As shown, it can be understood that 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 a plurality of connecting posts 2231 that can slide relative to the support plate 223 in a vertical direction. Specifically, two or four connecting posts 2231 can be symmetrically arranged, which will not be described in detail here. The end of the connecting post 2231 is fixedly connected to the base plate 221, and the connecting post 2231 is provided with a spring 2232. The spring 2232 is tightly pressed between the support plate 223 and the base plate 221. The support plate 223 is connected to the output end of the driving module 210.

[0036] By setting the connecting column 2231 and the spring 2232, the substrate 221 can move toward the support plate 223 or reset back to the support plate 223, so that when the driving module 210 drives the suction module 220 to stick the paper, the spring 2232 can absorb the impact force of the substrate 221, play a buffering effect, and avoid breaking the paper tape.

[0037] Furthermore, the base plate 221 is provided with a reinforcing portion 2212 . The reinforcing portion 2212 protrudes from a side of the base plate 221 facing the support plate 223 . The connecting column 2231 is connected to the reinforcing portion 2212 .

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

[0039] Furthermore, the reinforcement portion 2212 is provided with an air duct, which passes through the substrate 221. The connecting tube 224 is sealed and connected to the air duct opening of the connecting portion through a sealing head 2241. At least some of the suction nozzles 222 are connected to the connecting tube 224 through the air duct. 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 direction of the substrate 221 are connected to the air duct; when the suction nozzles 222 are arranged diagonally, the suction nozzles 222 located at the diagonals of the substrate 221 are connected to the air duct. Optionally, the air duct can be a branch air duct with one inlet and multiple outlets. In this case, one connecting tube 224 can generate negative pressure for multiple suction nozzles 222 connected to the same air duct. The air duct can also be a straight channel with one inlet and one outlet. In this case, the connecting tube 224 corresponds one-to-one with the suction nozzles 222.

[0040] By providing an air passage that is sealed with the connecting tube 224 , the sealing between the suction nozzle 222 and the connecting tube 224 can be effectively improved, and the installation or removal of the connecting tube 224 can be facilitated.

[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 tube 224, the user can first pass the connecting tube 224 through the through hole 2233, then connect the sealing head 2241, and finally install the sealing head 2241 on the reinforcing portion 2212. The provision of the through hole 2233 can optimize the routing of the connecting tube 224, prevent the connecting tube 224 from accumulating in the gap between the base plate 221 and the support plate 223, and improve the ease of installation and removal of the connecting tube 224.

[0043] Reference Figure 1 As shown, it is understandable that the storage device 100 includes a storage frame 110 and a lifting member 120, and the storage frame 110 is arranged to form a storage cavity. Specifically, the storage frame 110 includes a plurality of limiting columns 111 and a base plate 112, and the plurality of limiting columns 111 are arranged at intervals along the circumference of the base plate 112, and a storage cavity is formed between the plurality of limiting columns 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 in the vertical direction. Optionally, the lifting member 120 can be a vertically arranged ball screw slider structure, or a vertically arranged push rod structure, etc., which will not be repeated here.

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

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

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

[0047] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
