Description

Technical Field

[0001] This invention relates to the field of conveying devices, specifically a quick order change device for digital printers. Background Technology

[0002] In the digital printing machine industry, the demands for diversified products and simple, user-friendly operation are becoming increasingly stringent, leading to common problems with most equipment on the market. Digital printers handle both single-product printing and bulk orders, as well as orders with small printing areas but large overall dimensions. This significantly increases the difficulty for operators, as each repetitive task requires moving the printer off the track, switching to another printing job, and then returning it to the track. This hinders production efficiency and cost reduction.

[0003] Existing technology moves the printer by sliding along a track, which is convenient for placing and changing different printed objects. However, in this process, different objects have different widths and thicknesses. When moving the printer with a conventional sliding track structure, it is necessary to adjust the position of the track according to the size of the object and limit and fix the object before moving the printer to print the object. This process requires adjusting the position for different objects and also requires manual fixing of the object, which is inconvenient and has low printing efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a rapid order change device for digital printers to solve the problems mentioned in the background. The invention features a novel structure. An object is clamped by a fixture consisting of two sets of upper and lower plates in a drive assembly, and then fed into the printing table via a slide. During the clamping process, the upper and lower plates measure the width and thickness of the object, allowing for easy manual adjustment of the height of the base plate and baffle. This design is suitable for various objects being fed into the printing table, maintaining sufficient contact surface to secure the object. The two sets of clamps can be used cyclically, improving the feeding and retrieval process and avoiding the inconvenience of manual replacement.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a digital printer quick order exchange device for inbound shipment, comprising a table, with baffles at the front and rear ends of the top of the table, and an inlet / outlet at the bottom of the baffle at the front of the table; slide rails on both sides of the two sets of baffles, with a printer body mounted on the surface of the slide rails; bases fixed on both sides of the bottom of the printer body, with multiple pulleys equidistantly mounted on the bottom and sides of the bases; a drive assembly on the surface of the table, the drive assembly including a slide plate; an L-shaped slide groove opened on the surface of the table, with the longitudinal direction of the slide groove corresponding to the inlet / outlet; a slide plate fixed on the outer side of the table, with both ends of the slide plate connected to the transverse and longitudinal directions of the slide groove, respectively; the slide groove and the slide plate forming a complete annular sliding groove; the drive assembly having two sets of lower plates, with the lower plates located diagonally opposite to the sliding groove formed by the slide groove and the slide plate; a ring rope provided inside the sliding groove formed by the slide groove and the slide plate, and the lower plates connected to the ring rope sliding along the slide groove and the slide plate with the ring rope.

[0006] Furthermore, the bottom of the table is fixed with multiple sets of support pillars, and the support pillars are respectively fixedly connected to the bottom side of the table and the bottom outer side of the slide plate.

[0007] Furthermore, traction ropes are fixed on both sides of the printer body, and take-up seats are fixed on the outer sides of the table side panels corresponding to the positions of the traction ropes. The two ends of the traction ropes are respectively wound onto the take-up shafts of the two take-up seats. A first motor is fixed to the outer end of the take-up seat, and the output end of the first motor is fixedly connected to the take-up shaft of the take-up seat.

[0008] Furthermore, the slide rail component includes a fixed slide rail. The top two sides of the table away from the entrance and exit are provided with fixed slide rails, and one end of the fixed slide rail is fixedly connected to the adjacent baffle. The other end of the fixed slide rail is fixed with a vertical plate, and the other end of the vertical plate is fixedly connected to the baffle on the entrance and exit side.

[0009] Furthermore, a base plate is slidably connected to the bottom of the vertical plate, the base plate is flush with the horizontal plane of the fixed slide rail, and multiple sets of first electric push rods are fixed at equal intervals on the outer side of the vertical plate, and the extended ends of the first electric push rods are fixedly connected to the base plate.

[0010] Furthermore, a second electric push rod is fixed to the remaining triangular parts of the table, excluding the slide plate, and the extended end of the second electric push rod is fixedly connected to the outside of the baffle.

[0011] Furthermore, the drive assembly also includes a second motor. The second motor is located at the center of the slide and the slide plate and is fixed to the bottom of the table. A rotating plate is fixed to the output end of the second motor. First telescopic plates are symmetrically fixed on both sides of the rotating plate. A movable notch is provided at the bottom of the slide and the slide plate. A connecting block is provided through the movable notch at the extended end of the first telescopic plate and is fixedly connected to the ring rope.

[0012] Furthermore, the upper end of the lower plate is provided with an upper plate, and both the upper plate and the lower plate are provided with moving grooves. Telescopic plates are slidably inserted into both sides of the moving grooves of the upper plate and the lower plate, and springs are fixed at both ends of the upper plate and the lower plate.

[0013] Furthermore, a bidirectional screw is rotatably mounted on the outer surface of the upper plate via a bearing seat, and two sets of threaded blocks are symmetrically threaded on the surface of the bidirectional screw. The threaded blocks are fixedly connected to the receiving end of the telescopic plate.

[0014] Furthermore, a movable wheel is rotatably mounted on the bottom of the lower plate via a shaft, and the movable wheel slides along the inner wall of the slide groove and slide plate. A sliding seat is rotatably mounted on the bottom of the movable wheel via a bearing, and the sliding seat is fixed on the surface of the loop rope.

[0015] The beneficial effects of this invention are:

[0016] 1. According to the thickness of the object, the height of the upper plate is adjusted so that the second telescopic plate connecting the two can be extended or shortened. Then, the object is clamped between the upper plate and the lower plate by the spring force. During this process, the distance between the upper plate and the lower plate can be measured by some measuring devices. The baffle, slide rail and printer body are pushed to move upward by the second electric push rod. The position of the inlet and outlet and the bottom plate are adjusted to correspond to the thickness of the object, so as to facilitate the object to enter and exit the table for printing and fix the two sides of the object.

[0017] 2. This invention uses the rotation of a bidirectional screw to cause two threaded blocks to move in opposite directions, thereby moving two sets of second telescopic plates. The top and bottom of the second telescopic plates slide along the moving grooves of the upper and lower plates, respectively. The distance of the second telescopic plates corresponds to the width of the object. At the same time, the first electric push rod drives the bottom plate to slide along the bottom of the vertical plate, adjusting the length of the bottom plate beyond the vertical plate, thus making it suitable for limiting and fixing objects of different widths.

[0018] 3. The clamp on one side of the slide groove can carry new objects into the table for printing, while the clamp on the other side sends out the printed objects and returns to the inlet / outlet position to wait for the next set of clamped objects. This method achieves a cyclical rotation effect, improving the efficiency of feeding and sending out different objects as well as printing efficiency. At the same time, the clamping and pulling method makes it more convenient for objects to enter and exit the table.

[0019] 4. In this invention, the second motor drives the rotating plate to rotate, and the two sets of first telescopic plates rotate synchronously with the rotating plate. The connecting block passing through the moving notch drives the ring rope to move along the inside of the slide groove and slide plate. During this process, because the length and width of the track are different, the first telescopic plate automatically extends and retracts to adjust its length to maintain the connection with the connecting block and drive the ring rope to move in a cycle.

[0020] 5. Compared with the prior art, the present invention uses a clamp composed of two sets of upper and lower plates of the drive component to hold the object and feed it into the table through a slide. During the clamping process, the upper and lower plates measure the width and thickness of the object, so as to facilitate manual adjustment of the height of the base plate and the baffle. It is suitable for feeding different objects into the table for printing, maintaining sufficient contact surface to fix the object. The two sets of clamps can be used in cycles, which can improve the feeding and taking out of the object and avoid the inconvenience of manual replacement. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] Please see Figures 1 to 7 This invention provides a technical solution: a quick order change device for a digital printer, comprising a table 1, with baffles 11 at the front and rear ends of the top of the table 1, and an inlet / outlet 12 at the bottom of the baffle 11 at the front end of the table 1. Slide rails 3 are provided on the bottom sides of the two sets of baffles 11, and a printer body 2 is mounted on the surface of the slide rails 3. Bases 24 are fixed to the bottom sides of the printer body 2, and multiple casters 25 are equidistantly mounted on the bottom and sides of the bases 24. A drive assembly 5 is provided on the surface of the table 1, the drive assembly 5 including a slide rail 51. An L-shaped groove 14 is formed on the surface of the table 1, and the longitudinal direction of the groove 14 corresponds to the inlet / outlet 12. The slide rail 51 is fixed to the outer side of the table 1, and both ends of the slide rail 51 are connected to the transverse and longitudinal directions of the groove 14, respectively. 4. A complete annular sliding groove is formed with the slide plate 51. The drive assembly 5 is provided with two sets of lower plates 57, and the lower plates 57 are located at the diagonal of the sliding groove formed by the slide 14 and the slide plate 51. The sliding groove formed by the slide 14 and the slide plate 51 is provided with a ring rope 59. The lower plate 57 is connected to the ring rope 59 and slides along the slide 14 and the slide plate 51 with the ring rope 59. When using the device, the printing object is clamped at one end by the upper plate 56 and the lower plate 57. Then, the height of the slide rail 3 and the baffle 11 is adjusted. The object is sent to the table 1 along the slide 14 by the drive assembly 5. The printer body 2 moves along the slide rail 3 to print. After printing, the object is sent out along the slide plate 51 by the drive assembly 5. The new object is transported by the clamps of the other set of upper plates 56 and lower plates 57.

[0031] In this embodiment, multiple sets of support columns 13 are fixed to the bottom of the table 1, and the support columns 13 are fixedly connected to the bottom side of the table 1 and the bottom outer side of the slide plate 51 respectively. The support columns 13 serve to provide support. Therefore, the position of the support columns 13 needs to ensure that the slide plate 51 added on the outside maintains stability and load-bearing capacity. At the same time, the position of the support columns 13 does not interfere with the rotation of the first telescopic plate 55.

[0032] In this embodiment, traction ropes 23 are fixed on both sides of the printer body 2. Take-up seats 21 are fixed on the outer sides of the baffles 11 on both sides of the table 1 at the positions corresponding to the traction ropes 23. The two ends of the traction ropes 23 are respectively wound onto the take-up shafts of the two take-up seats 21. A first motor 22 is fixed to the outer end of the take-up seat 21, and the output end of the first motor 22 is fixedly connected to the take-up shaft of the take-up seat 21. The first motor 22 drives the take-up shaft of the take-up seat 21 to rotate. The two take-up shafts of the two sets of baffles 11 unwind and rewind, so that the traction ropes 23 can pull the printer body 2 to move along the track and print the objects on the table 1.

[0033] In this embodiment, the slide rail component 3 includes a fixed slide rail 31. Fixed slide rails 31 are provided on both sides of the top of the table 1 on the side away from the inlet / outlet 12. One end of the fixed slide rail 31 is fixedly connected to an adjacent baffle 11. A vertical plate 32 is fixedly attached to the other end of the fixed slide rail 31, and the other end of the vertical plate 32 is fixedly connected to the baffle 11 on the side of the inlet / outlet 12. A base plate 34 is slidably connected to the bottom of the vertical plate 32. The base plate 34 is flush with the horizontal plane of the fixed slide rail 31. Multiple sets of first electric push rods 33 are equidistantly fixed to the outer side of the vertical plate 32, and the extended ends of the first electric push rods 33 are fixedly connected to the base plate 34. The table 1, excluding the slide rail 51, has three other components... A second electric push rod 4 is fixed at the corner, and the extended end of the second electric push rod 4 is fixedly connected to the outside of the baffle 11. An upper plate 56 is provided at the upper end of the lower plate 57, and a moving groove is provided on the surface of both the upper plate 56 and the lower plate 57. A second telescopic plate 512 is slidably inserted into both sides of the moving groove of the upper plate 56 and the lower plate 57. A spring 513 is fixed at both ends of the upper plate 56 and the lower plate 57. A bidirectional screw 58 is rotatably mounted on the outer surface of the upper plate 56 through a bearing seat, and two sets of threaded blocks 511 are symmetrically threaded on the surface of the bidirectional screw 58. The threaded blocks 511 are fixedly connected to the receiving end of the second telescopic plate 512. The height of the lower plate 57 is affected by the bottom slide. Under the action of 515, the height of the upper plate 56 is adjusted according to the thickness of the object, so that the second telescopic plate 512 connected to the two can be extended or shortened. Then, the object is clamped between the upper plate 56 and the lower plate 57 by the elastic force of the spring 513. During this process, the distance between the upper plate 56 and the lower plate 57 can be measured by some measuring devices, such as existing rangefinders, so as to know the thickness of the object. The second electric push rod 4 pushes the baffle 11, the slide rail 3 and the printer body 2 to move upward, adjusting the position of the inlet / outlet 12 and the bottom plate 34 to correspond to the thickness of the object, so as to facilitate the object to enter and exit the table 1 for printing and fix the two sides of the object. One end of the bidirectional screw 58 is connected to a small Driven by a type of motor (not shown in the figure), the rotation of the bidirectional screw 58 causes two threaded blocks 511 to move in opposite directions, driving two sets of second telescopic plates 512 to move. The top and bottom of the second telescopic plates 512 slide along the moving grooves of the upper plate 56 and the lower plate 57, respectively (the moving grooves are not labeled in the figure and can be a common sliding connection between a slider and a groove, used to limit and fix the two ends of the second telescopic plates 512). The distance of the second telescopic plates 512 corresponds to the width of the object. At the same time, the first electric push rod 33 drives the bottom plate 34 to slide along the bottom of the vertical plate 32, adjusting the length of the bottom plate 34 beyond the vertical plate 32, thus making it suitable for limiting and fixing objects of different widths.

[0034] In this embodiment, the drive assembly 5 further includes a second motor 53. The second motor 53 is located at the center of the slide groove 14 and the slide plate 51, and is fixed to the bottom of the table 1. A rotating plate 54 is fixed to the output end of the second motor 53. First telescopic plates 55 are symmetrically fixed on both sides of the rotating plate 54. A movable notch 52 is provided at the bottom of the slide groove 14 and the slide plate 51, and a connecting block 510 is provided at the extended end of the first telescopic plate 55 through the movable notch 52. The connecting block 510 is connected to the loop rope 59. The lower plate 57 is fixedly connected, and a movable wheel 514 is rotatably mounted on the bottom of the lower plate 57 via a shaft. The movable wheel 514 slides along the inner wall of the slide groove 14 and the slide plate 51. A slide seat 515 is rotatably mounted on the bottom of the movable wheel 514 via a bearing, and the slide seat 515 is fixed to the surface of the ring rope 59. Since the clamps composed of the upper plate 56 and the lower plate 57 are located at two opposite corners of the circular track and are driven by the same ring rope 59, the two sets of clamps move in opposite directions (the circular track is composed of the slide groove 14 and the slide plate 51). In the sliding area, the clamp is a combination of upper plate 56 and lower plate 57. The second motor 53 drives the rotating plate 54 to rotate, and the two sets of first telescopic plates 55 rotate synchronously with the rotating plate 54. The connecting block 510 passing through the moving notch 52 drives the ring rope 59 to move along the slide groove 14 and the slide plate 51. During this process, because the length and width of the track are different, the first telescopic plates 55 automatically extend and retract to adjust their length to maintain the connection with the connecting block 510 and drive the ring rope 59 to move in a cycle. The clamp located on the longitudinal side of the slide groove 14 can drive the new The object is fed into the table 1 for printing, and the clamp on the other side sends out the printed object and returns to the position of the inlet and outlet 12 to wait for the next set of clamped objects. This method achieves the effect of cyclical rotation, improves the efficiency of feeding and sending out different objects and printing efficiency, and at the same time, the clamping and pulling method makes it easier for objects to enter and exit the table 1 (the moving wheel 514 at the bottom of the lower plate 57 slides along the slide groove 14 and the inside of the slide plate 51, adapts to the inside of the slide groove, and is connected to the ring rope 59 through the slide seat 515).

[0035] When using the device, the height of the upper plate 56 is adjusted according to the thickness of the object, causing the second telescopic plate 512 connected to it to extend or shorten. Then, the object is clamped between the upper plate 56 and the lower plate 57 by the elastic force of the spring 513. During this process, the distance between the upper plate 56 and the lower plate 57 can be measured using a measuring device, such as a rangefinder, to determine the thickness of the object. The second electric push rod 4 pushes the baffle 11, the slide rail 3, and the printer body 2 upwards, adjusting the positions of the inlet / outlet 12 and the base plate 34 to correspond to the object. The thickness facilitates the entry and exit of objects onto and off the table 1 for printing and fixing the objects on both sides. One end of the bidirectional screw 58 is driven by a small motor (not shown in the figure). Through the rotation of the bidirectional screw 58, the two threaded blocks 511 move in opposite directions, driving the two sets of second telescopic plates 512 to move. The top and bottom of the second telescopic plates 512 slide along the moving grooves of the upper plate 56 and the lower plate 57, respectively. The distance between the second telescopic plates 512 corresponds to the width of the object. At the same time, the first electric push rod 33 drives the bottom plate 34 along the bottom of the vertical plate 32. The bottom plate 34 slides and adjusts to extend beyond the vertical plate 32, thus accommodating objects of different widths for positioning and fixing. The object is then pulled along the slide groove 14 and fed into the table 1 by the drive assembly 5. The printer body 2 moves along the slide rail 3 to print on the object. After printing, the second motor 53 drives the rotating plate 54 to rotate, and the two sets of first telescopic plates 55 rotate synchronously with the rotating plate 54. The connecting block 510, passing through the moving notch 52, drives the ring rope 59 to move along the slide groove 14 and the slide plate 51. During this process, because the length and width of the tracks are different... Therefore, the first telescopic plate 55 automatically extends and adjusts its length to maintain connection with the connecting block 510 and drives the ring rope 59 to move in a cycle. The clamp located on one side of the longitudinal direction of the slide 14 can carry new objects into the table 1 for printing, while the clamp on the other side sends out the printed objects and returns to the position of the inlet and outlet 12 to wait for the next set of clamped objects. In this way, the effect of cyclic rotation is achieved, which improves the efficiency of feeding and sending out different objects as well as the printing efficiency. At the same time, the clamping and pulling method makes it more convenient for objects to enter and exit the table 1.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
