Abstract
Description
Technical Field
[0001] The utility model belongs to the field of color box printing production equipment, and particularly relates to a deviation rectifying device for color box printing. Background Art
[0002] Nowadays, color box printing production is often carried out in large quantities, with sequential operations on an assembly line. First, the color box board is cut, then printed, and finally dried to complete the production. However, during the conveyor belt drive in the color box production process, it is very likely that the position of the color box will shift during the conduction. Since the finally produced color boxes are stacked from bottom to top in sequence, if one of the color boxes shifts and rotates, then during the stacking process, the upper color boxes will press on the lower color boxes in sequence, resulting in an uneven state of the completed production color boxes. Then, it is necessary to manually twist the offset color boxes, which not only takes time and effort but may also damage the color boxes during the twisting process, leading to an increase in the defective rate of the production process. Content of the Utility Model
[0003] To solve the above technical problems, the utility model provides a deviation rectifying device for color box printing. By adding this deviation rectifying device to the conveyor belt, when the color box abuts against the transition plate under the drive of the driving component, the pipe rectifying plate is driven by the air cylinder, and the two groups of pipe rectifying plates approach each other until they push the color box to correct its position. After the deviation is corrected, the transition plate is rotated to transfer the color box to the next process, thus completing the deviation rectification of the color box during the production process.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A deviation rectifying device for color box printing, comprising a machine table, a driving assembly and a deviation rectifying assembly. The driving assembly includes a plurality of driving wheels and a plurality of driving shafts. The driving wheels are connected to the driving shafts. The plurality of driving shafts are rotatably connected to the machine table and driven by a sprocket to rotate synchronously. The deviation rectifying assembly includes two groups of cylinders, two groups of pipe straightening plates, a motor and a transition plate. The two groups of cylinders are oppositely distributed on the machine table. The output ends of the two groups of cylinders are respectively connected to the two groups of pipe straightening plates. The opposite surfaces of the two groups of pipe straightening plates are parallel to each other and do not contact each other. The planes where the lower end surfaces of the two groups of pipe straightening plates are located are parallel to the upper cutting surfaces of the plurality of driving wheels. A plurality of guiding columns are provided on the lower end surface of the pipe straightening plate. The plurality of guiding columns are respectively inserted between the plurality of driving shafts and do not contact the driving shafts. A limiting column is provided on the guiding column. The limiting column points to a limiting hole on the machine table and cooperates with the limiting hole. The transition plate is composed of a plurality of transition columns and a transition shaft and has an I-shaped structure. The transition shaft is rotatably connected to the machine table. The motor is arranged on the machine table and drives the transition shaft to rotate. The transition columns are located between the plurality of driving wheels and do not contact the driving wheels. The lower end surface of the transition column abuts against the driving shaft. The included angle formed between the transition columns distributed at both ends of the transition shaft is less than 180°.
[0006] The deviation rectification device for printing color boxes with this structure has the machine platform set in the middle of the front and rear two groups of conveyor belts, which is used to rectify the position of the color boxes during the conveying process. Therefore, a driving force is required on the machine platform to convey the color boxes. Thus, a driving component is set up. A number of driving shafts included in the driving component are rotatably connected to the machine platform, and a set of sprockets links a number of groups of driving shafts together, enabling each group of driving shafts to rotate synchronously. Simply driving the driving shafts cannot well convey the color boxes placed on them. Therefore, a number of driving wheels are connected to the driving shafts, and an anti-slip ring is sleeved on the outer sidewall of the driving wheels. Therefore, when the driving shafts are driven, all the driving wheels will be driven to rotate synchronously. Thus, the color boxes can be driven in position under the driving force of the anti-slip rings on the driving wheels. When the driving shafts stop, the color boxes will also stop. Therefore, in order to rectify the position of the color boxes, a deviation rectification component is set up. Two cylinders on the deviation rectification component respectively drive two pipe rectifying plates, so that the two pipe rectifying plates are respectively arranged on the left and right sides of the machine platform. When the cylinders are started simultaneously, the pushed pipe rectifying plates approach each other, so they will abut against the side edges of the color boxes. When the color boxes are skewed, the position of the color boxes can be rectified. Since the plane where the lower end surface of the pipe rectifying plate is located is parallel to the upper tangent plane of the driving wheel and they do not contact each other, if the color boxes are lower than the lower end surface of the pipe rectifying plate, it will cause the pipe rectifying plate to lose the function of deviation rectification. Therefore, a number of guiding columns are set on the lower end surface of the pipe rectifying plate, and the guiding columns are respectively inserted through the centers between the driving shafts. The left and right sides of the guiding columns do not contact the driving shafts. Therefore, the downward-extending guiding columns can increase the downward contact distance. Even if the color boxes are lower than the lower end surface of the pipe rectifying plate, they will still be abutted by the guiding columns, thus achieving the effect of deviation rectification. In order to prevent the pipe rectifying plate from rotating during the process of being pushed by the cylinder, a limiting column is set on the guiding column. The limiting column points to the limiting hole on the machine platform and is matched with the limiting hole. Therefore, the horizontal translation of the pipe rectifying plate is restricted by the limiting column and the limiting hole, avoiding the rotation of the pipe rectifying plate after being pushed by the cylinder's thrust, ensuring deviation rectification while also preventing the pipe rectifying plate from touching the driving shafts during translation and avoiding damage to the pipe rectifying plate.
[0007] However, under this structure, the color box may be conveyed too far during the transmission process, causing the color box to exceed the correction range of the tube main plate, so that the color box is pushed by the end of the tube main plate and causes a greater tilt. Therefore, a structure is needed to prevent the color box from being conveyed too far during the transmission process. Therefore, a motor and a transition plate are added. The motor is arranged on the machine table, and the transition plate is an I-shaped structure composed of a number of transition columns and transition shafts. The transition shaft is rotatably connected to the machine table and driven by the motor. During the rotation of the transition shaft, the transition column is also driven to rotate. Since the angle between the transition columns at both ends of the transition shaft is less than 180°, when the motor drives the transition column at the left end to abut against the drive shaft, the transition column at the right end is parallel to the upper section of the drive wheel. When the color box is transmitted over, it first abuts against the end face of the transition column. After being restricted from moving forward by the transition column, the cylinder drives the tube plate to complete the side correction of the color box. After the correction is completed, the tube plate returns to its original position under the drive of the cylinder, and the transition column rotates again under the drive of the motor, so that the transition columns on the left and right ends are not in contact with the drive shaft. Therefore, after the color box is freed from the forward restriction, it will be driven by the driving wheel and enter the upper end position of the transition column, cross the transition shaft and enter the transition column on the left end. At this time, the transition shaft is rotated again, so that the transition column on the left end abuts against the driving shaft again. The color box that has completed the correction enters the next process under the continuous driving force of the driving wheel, and the transition column on the right rises again to abut against the next color box to be corrected, thereby achieving the effect of continuous production.
[0008] Furthermore, a touch switch is provided on the end surface of the transition column pointing to the guide plate.
[0009] Compared with the prior art, the utility model has the advantages that: through the setting of the driving shaft and the driving wheel, a transmission force is provided for the transportation of the color box, and when the color box that has completed the transportation enters the position of the tube main plate, it is pushed by the tube main plate to correct its position, and a transition plate is set at the front end of the transportation color box, which not only limits the forward transportation position of the color box, but also assists the transportation of the color box, making the entire production process more efficient and stable.

[0017] The specific embodiments of the present utility model will be described below in conjunction with the drawings:
[0018] Such as Figures 1-4As shown in the figure, a deviation rectifying device for color box printing includes a machine table 1, a driving component 2 and a deviation rectifying component 3. The driving component 2 includes a number of driving wheels 21 and a number of driving shafts 22. The driving wheels 21 are connected to the driving shafts 22. The number of driving shafts 22 are rotatably connected to the machine table 1 and are driven by a sprocket to rotate synchronously. The deviation rectifying component 3 includes two groups of cylinders 31, two groups of pipe rectifying plates 32, a motor 33 and a transition plate 34. The two groups of cylinders 31 are respectively distributed oppositely on the machine table 1. The output ends of the two groups of cylinders 31 are respectively connected to the two groups of pipe rectifying plates 32. The opposite surfaces of the two groups of pipe rectifying plates 32 are parallel to each other and do not contact each other. The plane where the lower end surfaces of the two groups of pipe rectifying plates 32 are located is parallel to the upper cutting surfaces of the number of driving wheels 21. A number of guiding columns 321 are provided on the lower end surfaces of the pipe rectifying plates 32. The number of guiding columns 321 respectively penetrate between the number of driving shafts 22 and do not contact the driving shafts 22. A limiting column 322 is provided on the guiding column 321. The limiting column 322 points to a limiting hole 11 on the machine table 1 and cooperates with the limiting hole 11. The transition plate 34 is composed of a number of transition columns 341 and a transition shaft 342 to form an I-shaped structure. The transition shaft 342 is rotatably connected to the machine table 1. The motor 33 is arranged on the machine table 1 and drives the transition shaft 342 to rotate. The transition columns 341 are located between the number of driving wheels 21 and do not contact the driving wheels 21. The lower end surface of the transition column 341 abuts against the driving shaft 22. The included angle formed between the transition columns 341 distributed at both ends of the transition shaft 342 is less than 180°.
[0019] Further, a touch switch 343 is provided on the end surface of the transition column 341 pointing to the rectifying plate.
[0020] The working mode of the present utility model is described as follows:
[0021] The deviation rectification device for printing color boxes with this structure has the machine table 1 arranged in the middle of the front and rear two groups of conveyor belts, which is used to rectify the position of the color boxes during the conveying process. Therefore, a driving force is required on the machine table 1 to convey the color boxes. Thus, a driving component 2 is set up. A number of driving shafts 22 included in the driving component 2 are rotatably connected to the machine table 1, and a set of chain wheels are used to link a number of groups of driving shafts 22 together, so that each group of driving shafts 22 rotates synchronously. This structure is a relatively common existing technology, so it will not be elaborated in this article. Simply driving the driving shaft 22 cannot well drive the color boxes placed on it. Therefore, a number of driving wheels 21 are connected to the driving shaft 22, and an anti-slip ring is sleeved on the outer side wall of the driving wheel 21. Therefore, when the driving shaft 22 is driven, it will drive all the driving wheels 21 to rotate synchronously. Thus, the color boxes can be driven in position under the driving of the friction force of the anti-slip ring on the driving wheels 21. When the driving shaft 22 stops, the color boxes will also stop. Therefore, in order to rectify the position of the color boxes, a deviation rectification component 3 is set up. Two cylinders 31 on the deviation rectification component 3 respectively drive two pipe rectifying plates 32, so that the two pipe rectifying plates 32 are respectively arranged on the left and right sides of the machine table 1. When the cylinders 31 are started simultaneously, the pushed pipe rectifying plates 32 approach each other, so they will abut against the side edges of the color boxes. When the color boxes are skewed, the position of the color boxes can be rectified. Since the plane where the lower end surface of the pipe rectifying plate 32 is located is parallel to the upper cutting surface of the driving wheel 21 and they do not contact each other, if the color boxes are lower than the lower end surface of the pipe rectifying plate 32, it will cause the pipe rectifying plate 32 to lose the function of deviation rectification. Therefore, a number of guiding columns 321 are arranged on the lower end surface of the pipe rectifying plate 32, and the guiding columns 321 are respectively inserted into the centers between the driving shafts 22. The left and right sides of the guiding columns 321 do not contact the driving shafts 22. Therefore, the downward-extending guiding columns 321 can increase the downward contact distance. Even if the color boxes are lower than the lower end surface of the pipe rectifying plate 32, they will still be abutted by the guiding columns 321, thus achieving the effect of deviation rectification. In order to prevent the pipe rectifying plate 32 from rotating during the process of being pushed by the cylinder 31, a limiting column 322 is arranged on the guiding column 321. The limiting column 322 points to the limiting hole 11 on the machine table 1 and cooperates with the limiting hole 11. Therefore, the horizontal translation of the pipe rectifying plate 32 is restricted by the limiting column 322 and the limiting hole 11, avoiding the rotation of the pipe rectifying plate 32 after being subjected to the thrust of the cylinder 31. While ensuring deviation rectification, it also avoids the pipe rectifying plate 32 touching the driving shaft 22 during the translation process, preventing damage to the pipe rectifying plate 32.
[0022] However, in this structure, it is very likely that the color box will be over-transported during the conveying process, resulting in the color box exceeding the deviation correction range of the tube straightening plate 32, causing the color box to be pushed by the end of the tube straightening plate 32 and causing a greater inclination. Therefore, a structure needs to be set up to prevent the color box from being over-transported during the conveying process. Therefore, a motor 33 and a transition plate 34 are added. The motor 33 is arranged on the machine table 1, and the transition plate 34 is composed of a number of transition columns 341 and a transition shaft 342 to form an I-shaped structure. The transition shaft 342 is rotatably connected to the machine table 1 and is driven by the motor 33. During the rotation of the transition shaft 342, the transition columns 341 will also rotate. Since the included angle between the transition columns 341 distributed at both ends of the transition shaft 342 is less than 180°, when the motor 33 drives the left transition column 341 to abut against the driving shaft 22, the right transition column 341 is parallel to the upper tangent plane of the driving wheel 21. When the color box is conveyed over, it first abuts against the end face of the transition column 341 and is restricted from moving forward by the transition column 341. Then, the cylinder 31 drives the tube straightening plate 32 to complete the deviation correction of the side of the color box. After the deviation correction is completed, the tube straightening plate 32 returns to its original position under the drive of the cylinder 31, and the transition column 341 rotates again under the drive of the motor 33, so that neither the left nor the right transition column 341 contacts the driving shaft 22. Therefore, after the color box is released from the forward restriction, it will be driven by the driving wheel 21 and enter the upper position of the transition column 341, cross the transition shaft 342 and enter the left transition column 341. At this time, the transition shaft 342 is rotated again so that the left transition column 341 abuts against the driving shaft 22 again. The color box that has completed the deviation correction enters the next process under the continuous driving force of the driving wheel 21, and the right transition column 341 rises again to abut against the next color box to be corrected, achieving the effect of continuous production. However, during this production process, the deviation correction of the tube straightening plate 32 must be carried out after the color box abuts against the end face of the transition column 341. Therefore, a touch switch 343 is added to the end face of the transition column 341 pointing to the guiding plate. Once the color box touches the touch switch 343 during the transmission process, the position deviation correction of the tube straightening plate 32 is synchronized. With this setting, the overall production process will be smoother.
[0023] The beneficial effects of the present utility model are as follows: Through the setting of the driving shaft 22 and the driving wheel 21, driving force is provided for the transportation of the color box. When the color box that has completed the transportation enters the position of the tube straightening plate 32, it is subjected to the pushing force of the tube straightening plate 32 for position deviation correction. A transition plate 34 is arranged at the front end of the transported color box. While restricting the position of the color box transported forward, it can also assist in the transportation of the color box, making the entire production process more efficient and stable.
[0024] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
