The transmission device sequentially transmits the printing medium to each station for processing, such as printing, curing and other stations.

However, in some printing processes, a certain time interval is required between two adjacent processes so that the previous process can have enough time to react before the next process is carried out. The existing printing device usually extends the length of the transmission device between the two stations so that the printing medium is transmitted over a certain distance to achieve a certain time interval between the two adjacent stations. However, when the required interval time is long, the transmission device occupies a large area, which makes the entire device larger.

If there is no conflict, the various features in the embodiments and examples of the present invention can be combined with each other, all within the scope of protection of the present invention.

[0027] The following is combined with Figure 1 -Attached Figure 6 The present invention is further described in detail.

[0028] The embodiment of the present invention provides a cache transmission device for use in a printing device. The following is an explanation of the process of the cache transmission device in the printing device. It is worth noting that the cache transmission device is not limited to use in printing devices, and can be used in fields such as material transmission. Figure 6 As shown, the device includes: a first transmission mechanism 1 for transmitting materials; a buffer mechanism 2 for receiving materials output by the first transmission mechanism 1 and buffering the materials; and a second transmission mechanism 3 for discharging materials from the buffer mechanism 2 in a preset order.

[0029] In this embodiment, the preset order means that the materials enter the cache mechanism for caching according to a certain order, and the materials entered into the cache mechanism first are excluded first, or a certain designated one is excluded first, so the materials can be excluded according to the preset order. The cache transmission device is used in the printing device, and the transmitted material is the printing medium. The printing medium is explained as the transmitted material in the following; the printing medium is output from the first transmission mechanism 1 after printing. In other embodiments, it can be the transmission of the printing medium between any two processes; the printing medium is a flat or high box-shaped printing medium, such as paper printing medium, part of the printing medium of the packaging box, or printing medium such as the packaging box. The first transmission mechanism 1 transmits the printing medium of the previous station and transmits the printing medium to the buffer mechanism 2. The buffer mechanism 2 discharges the printing medium from the buffer mechanism 2 after a certain period of time, so that the printing medium flows to the next station after a certain period of time; the time for the second transmission mechanism 3 to discharge the printing medium from the buffer mechanism 2 can be adjusted according to the time required between the two stations, so that the time of the printing medium between the two stations meets the demand; since the buffer mechanism 2 is set to cache the printing medium, the time requirement between the two stations is met, and the distance between the first transmission mechanism 1 and the second transmission mechanism 3 can be shortened at the same time, and the transmission device is provided with a buffer mechanism to cache materials. Under the transmission device of the same length, the transmission time of the material is increased, thereby relatively reducing the volume of the buffer transmission device, thereby reducing the floor space of the buffer transmission device, and improving the technical effect of the space utilization rate of the buffer transmission device; thereby reducing the volume of the entire printing device, solving the technical problem that the existing printing device has a large volume; reducing the volume of the printing device, thereby reducing the floor space of the printing device, and obtaining the technical effect of improving the space utilization rate of the printing device.

[0030] Specifically, the buffer mechanism 2 is set corresponding to the output end of the first transmission mechanism 1, and the buffer mechanism 2 receives the first transmission mechanism 1. Specifically, the buffer mechanism 2 can be set lower than the output end of the first transmission mechanism 1, and the print media fall into the buffer mechanism 2 in sequence by their own gravity. When the print media are collected to a certain extent, the second transmission mechanism 3 is activated to discharge the print media; specifically, the second transmission mechanism 3 can be set below the buffer mechanism 2 and fit with the print media to transmit the print media out of the print media in sequence. In order to avoid mutual influence between two adjacent print media, the buffer mechanism 2 can also be set as a buffer mechanism 2 that can be raised and lowered, and a receiving portion 223 for receiving the print media is provided in the buffer mechanism 2, but the buffer mechanism 2 leaves space for the print media to contact the second transmission mechanism.

[0031] Preferably, the cache mechanism 2 caches materials in a vertical direction.

[0032] In this embodiment, the vertical direction is parallel to the gravity direction of the printing medium, that is, the printing medium is stacked from top to bottom or from bottom to top; the printing medium is stacked in the buffer mechanism 2 in sequence along the vertical direction, and the printing medium is stacked in the buffer mechanism 2 in sequence from bottom to top along the vertical direction. Since the printing medium is stacked in sequence along the vertical direction, that is, the printing medium is stacked along its thickness direction, the volume of the printing device occupied by the printing medium is reduced. Stacking the printing medium in the vertical direction of the printing device reduces the floor space of the printing device. At this time, the printing device is suitable for printing media with a smaller thickness, such as paper printing media; in other embodiments, the printing medium can be stacked in the printing medium in sequence from bottom to top along the vertical direction. At this time, the buffer mechanism is configured to be a ring-shaped conveyor belt for transmitting along the vertical direction, and a buffer portion for receiving the printing medium is evenly distributed on the outside of the conveyor belt; the first conveying mechanism and the second conveying mechanism are configured in the form of a conveyor belt, and the first conveying mechanism and the second conveying mechanism are configured in the form of a conveyor belt. The transmission mechanisms are arranged in parallel, and the projections of the first transmission mechanism and the second transmission mechanism in the horizontal direction at least overlap; the buffer mechanism is arranged corresponding to the output end of the first transmission mechanism and the feeding end of the second transmission mechanism; each buffer part of the buffer mechanism conveyor belt passes through the output end of the first transmission mechanism and the output end of the second transmission mechanism in sequence from top to bottom; the buffer part is provided with a space for the first transmission mechanism and the second transmission mechanism to pass through, and after the conveyor belt of the buffer mechanism drives the buffer part to correspond to the bottom of the first transmission mechanism, the first transmission mechanism outputs the printing medium, and due to the gravity of the printing medium itself, it falls into the buffer part, and the conveyor belt of the buffer mechanism drives the buffer part to move the printing medium for a certain period of time, and finally drives it to the feeding end of the second transmission mechanism, the printing medium is attached to the feeding end of the second transmission mechanism, the second transmission mechanism outputs the printing medium, and then the buffer part passes through the output end of the second transmission mechanism, and is transmitted back to the output end of the first transmission device through the other side, thus forming a cycle.

[0033] Preferably, combined Figure 4 as well as Figure 5 The cache mechanism 2 includes: a silo 22 and a lifting component 21; the silo 22 is used to receive the material output by the first transmission mechanism 1 and cache the material; the lifting component 21 is connected to the silo 22 by transmission, and the lifting component 21 drives the silo 22 to rise and fall.

[0034] In this embodiment, the lifting assembly 21 includes: a motor, a screw and a guide rail; the axial direction of the screw is parallel to the vertical direction, and the guide of the guide rail is parallel to the vertical direction; the screw is connected to the output end of the motor by transmission, the screw is passed through the silo 22, and the silo 22 is slidably connected to the guide rail; specifically, the motor drives the screw to drive the silo 22 to rise and fall along the guide direction of the guide rail, so that the silo 22 receives and caches the printing medium in sequence; specifically, the silo 22 is arranged corresponding to the output end of the first transmission mechanism 1, and the part of the silo 22 that receives the printing medium is flush with the output end of the first transmission mechanism 1. When the first transmission mechanism 1 is in operation, the silo 22 is moved to the upper and lower sides of the silo 22, and the silo 22 is moved to the lower side ... A transmission mechanism 1 outputs the printing medium, and after the silo 22 is stable, the lifting component 21 drives the silo 22 to rise or fall, so that the next part of the silo 22 corresponding to the printing medium is flush with the medium of the first transmission mechanism 1 until the entire silo 22 is filled with printing media; in this embodiment, the silo 22 is driven to rise to receive and cache the printing medium. Of course, in other embodiments, the silo 22 can also be driven to fall. At this time, the end of the silo 22 should correspond to the end of the output end of the first transmission medium, so that the output printing medium enters the silo 22 in sequence.

[0035] Preferably, the silo 22 includes: a plurality of receiving portions 223 , and a space for storing materials is formed between two adjacent receiving portions 223 .

[0036] In this embodiment, the hopper 22 further includes two side panels 221 set up facing each other, and a back panel 222 connected to the same side of the two side panels 221. The three sides connected to the receiving portion 223 are respectively connected to the two side panels 221 and the back panel 222. A discharge space for accommodating the printing medium is formed between the receiving portion 223 and the two side panels 221 and the back panel 222. The receiving portion 223 is configured as a plate-like structure, and all the receiving portions 223 are arranged in parallel along the vertical direction. The lifting assembly 21 drives the hopper 22, so that the receiving portions 223 in the hopper 22 are flush with the output end of the first transmission mechanism 1 in turn, thereby facilitating the printing medium to enter the hopper 22. The receiving portion 223 is configured so that one printing medium is stored in one The receiving portion 223 is arranged to avoid mutual influence between the two printing media. For example, if the ink printed on the printing medium is not dry, the printing media stacked together will influence each other and affect the printing effect. The receiving portion 223 can be arranged in parallel, and the receiving portion 223 is inclined relative to the horizontal plane. The lower end of the receiving portion 223 is in contact with the back plate 222, and the back plate 222 can slide along the lower end of each receiving portion 223, that is, one side of the vertical direction of the two side plates 221; the back plate 222 limits the printing medium in the space formed by the receiving portion 223 and the back plate 222, and the receiving portion 223 is slid upward in the vertical direction, so that the storage space for storing the printing medium formed between the back plate 222 and the receiving portion 223 is filled in sequence. Opening means destroying the relationship between the back plate 222 and the printing medium, so that the printing medium is first stored from the receiving portion 223 at the lower end, and the printing medium is cached from bottom to top until the silo 22 is full. After the cache time reaches the required time, the back plate 222 is pulled upward to open the space formed between the receiving portion 223 and the back plate 222 in turn. At this time, due to the inclined setting of the receiving portion 223, the printing medium is discharged from the silo 22 in turn as the space formed by the back plate 222 and the receiving portion 223 is opened. In this way, the printing medium is caught by its own gravity and discharged from the silo 22, which saves power resources, and the structure is simple and easy to implement, and can be implemented without setting a more complicated structure, thereby saving production. Cost; in order to allow two adjacent printing media to be transmitted at a certain distance, the back plate 222 opens one receiving portion 223 for a period of time, and then continues to open the next receiving portion 223; the distance between two adjacent receiving portions 223 is adjustable, so that the distance between two adjacent receiving portions 223 is adapted to printing media of different heights and sizes. Specifically, the receiving portion 223 is detachably installed between the two side plates 221, so that the distance between the two adjacent side plates 221 can be adjusted according to the height of the printing medium, so that the silo 22 is adapted to printing media of different heights; specifically, the two side plates 221 are provided with a clamping portion on one side facing each other, and the clamping portion is used to clamp the receiving portion 223;The distance between the two side panels 221 is adjustable so that the storage space can adapt to printing media of different widths. Specifically, a card slot is provided on the side wall of the back panel 222, and the side panels 221 are plugged into different card slots to adjust the distance between the two side panels 221. In addition, the receiving portion 223 is composed of two baffles provided on the side panels 221. At this time, the silo 22 is suitable for printing media with a harder material. The receiving portion 223 is composed of two baffles, so that the space between the two baffles can accommodate the end of the first transmission mechanism 1 or the end of the second transmission mechanism 3, so that the surface of the baffle receiving the printing medium is flush with the output end of the first transmission mechanism 1 or the second transmission mechanism 3, so as to facilitate the transmission of the printing medium to the receiving portion 223. ;

[0037] Preferably, the silo 22 is formed with a sliding space 224 , an end portion of the first transmission mechanism 1 is accommodated in the sliding space 224 , and the first transmission mechanism 1 can slide relative to the silo 22 .

[0038] In this embodiment, the first transmission mechanism 1 and the second transmission mechanism 3 have the same structure, and both use multiple transmission belts arranged in parallel; a U-shaped opening is opened at the corresponding position of each receiving portion 223, and the U-shaped openings of all the receiving portions 223 form a sliding space 224; the lifting component 21 drives the silo 22 to rise and fall, so that the first transmission mechanism 1 passes through the U-shaped opening of each receiving portion 223 in turn, so that the end of the output end of the first transmission mechanism 1 can slide relative to the silo 22 in the sliding space 224; the number of U-shaped openings is consistent with the number of transmission belts, and each transmission belt corresponds to each U-shaped opening; the receiving portion 223 is a baffle protruding from the side plate 221, and the two ends of the printing medium are respectively fitted with the baffle, so that the baffle receives the printing medium, and the space between all the opposite baffles forms a sliding space 224, so that the first transmission mechanism 1 or the second transmission mechanism 3 can slide along the sliding space 224.

[0039] Preferably, combined Figure 1 and Figure 4 The cache transmission device also includes: a first transport mechanism 4; the output end of the first transport mechanism 4 is connected to the cache mechanism 2, and the first transport mechanism 4 drives the cache mechanism 2 to reciprocate between the first transmission mechanism 1 and the second transmission mechanism 3.

[0040] In this embodiment, the first transport mechanism 4 transports the buffer mechanism 2 from the first transmission mechanism 1 to the second transmission mechanism 3. Correspondingly, the first transport mechanism 4 is provided with a loading position and a discharging position. The loading position corresponds to the output end of the first transmission mechanism 1, and the discharging position corresponds to the feeding end of the second transmission mechanism 3. When the buffer mechanism 2 is at the loading position, the first transmission mechanism 1 transports the printing medium to the buffer mechanism 2. When a certain amount is cached, the first transport mechanism 4 is started to transport it to the discharging position. The first transport mechanism 4 transports the printing medium, so that the printing medium is further cached on the transport mechanism, which can reduce the volume of the buffer mechanism 2 to increase the cache time, and can facilitate the selection of the second transmission mechanism 3, so as to facilitate the discharge of the printing medium. Specifically, the transport method of the first transport mechanism 4 can be in the form of a manipulator, a conveyor belt, a motor-driven turntable circular rotation, and a motor-driven lead screw reciprocating motion to achieve the reciprocating motion of the buffer mechanism 2.

[0041] Preferably, the transport direction of the first transport mechanism 4 is circular.

[0042] In the present embodiment, the first conveying mechanism 4 adopts a racetrack-shaped closed loop transmission direction, and a plurality of buffer mechanisms 2 can be arranged on the first conveying mechanism 4. After each buffer mechanism 2 is connected to the loading position and filled with printing media in turn, the first conveying mechanism 4 sequentially transmits the buffer mechanism 2 filled with printing media to the position of the discharge device, and the buffer mechanism 2 that has discharged the printing media returns to the loading position through a circular transmission to continue loading the printing media, and repeats this cycle. Under the condition of the same footprint of the printing device, by increasing the number of buffer mechanisms 2 on the conveying mechanism, the buffer time of the printing media is increased. According to actual needs, the transmission speeds of the first conveying mechanism 4, the first transmission mechanism 1 and the second transmission mechanism 3 can be set to increase the working speed of the entire device. The first conveying mechanism 4 is arranged in a ring shape, and the number of buffer mechanisms 2 can be increased, thereby increasing the buffer time, ensuring the buffer time required between two processes, while speeding up the working speed of the entire device, thereby improving production efficiency, and reducing the footprint of the printing device.

[0043] Preferably, combined Figure 2 as well as Figure 4 The first transporter 4 includes at least two slide rails, and a slide groove 41 is formed between the slide rails; a slider 225 is provided at the bottom of the cache mechanism 2 (see Figure 4 ), the slider 225 is accommodated in the slide groove 41 and can slide in the slide groove 41. The slider 225 slides along the inner wall of the slide groove 41; the bottom of the buffer mechanism 2 is provided with a slider 225, the first transport mechanism 4 is configured as a slide rail, and a slide groove 41 is formed between the slide rails for the slider 225 to cooperate with (see Figure 2), the slider 225 slides in the slide groove 41, and the slide groove 41 provides a guiding effect to the slider 225, thereby causing the entire cache mechanism 2 to move along the slide groove 41; the specific driving method for the cache mechanism 2 to rotate along the slide groove 41 can be a synchronous belt rotation, or it can be set to a ring-shaped gear rack structure.

[0044] Preferably, the buffer transmission device includes at least two buffer mechanisms 2 ; when one of the buffer mechanisms 2 receives the material output by the first transmission mechanism 1 , the second transmission mechanism 3 discharges the printing medium in the other buffer mechanism 2 .

[0045] In this embodiment, two cache mechanisms 2 are set to work alternately, which speeds up the printing speed of the entire device. In other embodiments, multiple cache mechanisms 2 can also be set. When there are multiple cache mechanisms 2 as mentioned above, the printing medium is installed therein and then output in turn in the second transmission mechanism 3, which speeds up the working speed of the entire device.

[0046] Preferably, the lifting assembly 21 drives the silo 22 to rise to receive and buffer the printing medium, and the lifting assembly 21 drives the silo 22 to descend so that the second transmission mechanism 3 discharges the printing medium.

[0047] In this embodiment, when the silo 22 is at the lowest position, the uppermost receiving portion 223 of the silo 22 is flush with or slightly lower than the output end of the first transmission mechanism 1, and the lifting assembly 21 rises, so that the printing medium is sequentially loaded onto the receiving portion 223 from top to bottom of the silo 22; when the lowermost receiving portion 223 is loaded with the printing medium, the silo 22 is at the highest position, and the first transport mechanism 4 drives the buffer mechanism 2 to the corresponding second transmission mechanism 3. At this time, the feeding end of the second transmission mechanism 3 is located below the silo 22. When the printing medium contacts the second transmission mechanism 3, the second transmission mechanism 3 will print the printing medium. The printing medium is discharged from the buffer mechanism 2. In this way, when the buffer mechanism 2 is transported from the loading position to the discharging position, the material bin 22 of the buffer mechanism 2 is located at the uppermost position, and there is space below the material bin 22 for the second transmission mechanism 3 to pass through. No additional power is required to drive the material bin 22 to rise, so that the second transmission mechanism 3 is located below the material bin 22. The structure is simple and ingenious. When the second transmission mechanism 3 has finished discharging the printing medium, the material bin 22 is driven to rise, so that the material bin 22 is separated from the second transmission mechanism 3, and the first transport mechanism 4 transports the buffer mechanism 2 to the top of the output end of the first transmission mechanism 1, and then the material bin 22 is lowered, and then The silo 22 returns to the lowest position for the next round of receiving and caching; in other preferred embodiments, the thickness of the first transmission mechanism 1 and the second transmission mechanism 3 is set to be thinner, so that the thickness of the first transmission mechanism 1 and the second transmission mechanism 3 are both smaller than the distance between two adjacent receiving parts 223; or the thickness of the first transmission mechanism 1 and the second transmission mechanism 3 is smaller than the distance between the two uppermost receiving parts 223 of the silo 22; an opening for the first transmission mechanism 1 and the second transmission mechanism 3 to pass through is set between the two side plates 221 corresponding to the two uppermost receiving parts 223, and the second transmission mechanism 3 discharges the printing medium after the printing medium is discharged. After that, at this time, the upper end surface of the feeding end of the second conveying mechanism 3 is flush with the highest receiving part 223 of the silo 22, and the first handling mechanism 4 drives the cache mechanism 2 to move toward the first conveying mechanism 1. At this time, the second conveying mechanism 3 leaves the silo 22 from the opening between the two side plates 221. When the cache mechanism 2 moves to the first conveying mechanism 1, the first conveying mechanism 1 enters the silo 22 from the opening, and the first conveying mechanism 1 and the second conveying mechanism 3 correspond to the sliding space 224. There is no need to raise the silo 22, so that the silo 22 can be separated from the first printing mechanism and the second printing mechanism, thereby completing the receiving and discharging of the printing medium.

[0048] Another aspect of an embodiment of the present invention provides a printing device, which includes any of the cache transmission devices described above.

[0049] The printing device includes any of the above-mentioned buffer transmission devices. Due to the buffer transmission device, the print medium is output from the first transmission mechanism 1 after printing. In other embodiments, it can be the transmission of the print medium between any two processes. The print medium is a flat print medium, such as a paper print medium, a part of the print medium of a packaging box, or other print medium. The first transmission mechanism 1 transmits the print medium of the previous station and transmits the print medium to the buffer mechanism 2. The buffer mechanism 2 discharges the print medium from the buffer mechanism 2 after a certain period of time, so that the print medium flows to the next station after a certain period of time. The time when the second transmission mechanism 3 discharges the print medium from the buffer mechanism 2 can be adjusted according to the time required between the two stations, so that the time of the print medium between the two stations meets the demand; since the buffer mechanism 2 is set to cache the print medium, the time requirement between the two stations is met, and at the same time, the distance between the first transmission mechanism 1 and the second transmission mechanism 3 can be shortened, thereby reducing the volume of the entire printing device, solving the technical problem that the existing printing device has a large volume; reducing the volume of the printing device, thereby reducing the footprint of the printing device, and obtaining the technical effect of improving the space utilization rate of the printing device.

[0050] Preferably, the printing device comprises a plurality of cache transmission devices, the number of the cache transmission devices is an even number, and the output end of the upstream cache transmission device is arranged corresponding to the feed end of the downstream cache transmission device.

[0051] In this embodiment, if Figure 1 As shown, two buffer transmission devices are provided, and the output end of the previous buffer transmission device is the second transmission mechanism 3, and the second transmission mechanism 3 is used as the feed end of the next buffer transmission device; when multiple buffer transmission devices are provided, the output end of the previous buffer transmission device is the feed end of the next buffer transmission device, so that multiple buffer transmission devices are connected. The number of buffer transmission devices is set to an even number, so that all printing media form a cycle after the first buffer transmission device and the second buffer transmission device are exchanged, ensuring that the time interval between each printing medium flowing through each process is as equal as possible, thereby ensuring the printing effect of each printing medium. Multiple buffer transmission devices are provided to make the printing medium cache longer.

[0052] Preferably, combined Figure 1-Figure 3 The cache transmission device in the printing device also includes a third transmission mechanism 6 and a second transport mechanism 5; the second transport mechanism 5 is provided with a cache mechanism 2, and the second transport mechanism 5 is used to drive the cache mechanism 2 to reciprocate between the second transmission mechanism 3 and the third transmission mechanism 6.

[0053] In the present embodiment, the structure of the second conveying mechanism 5 is consistent with the structure of the above-mentioned first conveying mechanism 4, and both adopt a circular track mode for transmission; the structure of the third conveying mechanism 6 is consistent with the second conveying mechanism 3 and the first conveying mechanism 1, and both adopt a conveyor belt for transmission; two buffer mechanisms 2 are arranged on the second conveying mechanism 5, and the structure of the buffer mechanism 2 is consistent with the structure of the above-mentioned buffer mechanism 2, which will not be described one by one here; it is worth noting that the second conveying mechanism 5, the buffer mechanism 2 on the second conveying mechanism 5, the second conveying mechanism 3 and the third conveying mechanism 6 constitute the buffer transmission device as mentioned above, at this time, the output end of the second conveying mechanism 3 is equivalent to the output end of the first conveying mechanism 1, and the feeding end of the third conveying mechanism is equivalent to the feeding end of the second conveying mechanism; in this embodiment, the buffer mechanisms 2 can be respectively the first buffer mechanism 2, the second buffer mechanism 2, the third buffer mechanism 2 and the fourth buffer mechanism 2; the first buffer mechanism 2 and the second buffer mechanism 2 are both arranged on the first conveying mechanism 4, and the third buffer mechanism 2 and the fourth buffer mechanism 2 are both arranged on the second conveying mechanism 5; the printing medium is transferred from the first conveying mechanism After being output by mechanism 1, the printing medium is sequentially loaded into the buffer mechanism 2 from top to bottom, and then discharged from the second transmission mechanism 3 from bottom to top. At this time, the printing medium first loaded into the buffer mechanism 2 is discharged later, resulting in the printing medium loaded later entering the second transmission mechanism 3 first; the printing medium on the second transmission mechanism 3 is loaded from top to bottom into the buffer mechanism 2 on the second conveying mechanism 5, and the printing medium is exchanged on the second conveying mechanism 5, and the printing medium first output by the second conveying mechanism 3 is output, so that the printing medium first output from the first conveying mechanism 1 is first output from the third conveying mechanism 6, so that all the printing media are transmitted in the original order, so as to ensure that the interval time between the two processes of all the printing media is consistent, reduce the printing effect of the printing media affected by different times, and ensure the printing effect; the first conveying mechanism 4 and the second conveying mechanism 5 are set, so that all the printing media form a cycle after the first conveying mechanism 4 and the second conveying mechanism 5 are exchanged, so as to ensure that the time interval between each printing medium flowing through each process is as equal as possible, so as to ensure the printing effect of each printing medium.
