Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to an offset printing machine. Background Art

[0002] During the production and processing of woven bags, in order to explain the materials inside, text or images are often printed on their surface. In the prior art, offset printing machines are often used to print text or images. The offset printing machine uses a roller as a printing plate, and prints the text and image to be printed on the surface of the roller. During the rolling connection between the woven bag and the roller, the text or image can be printed on the woven bag.

[0003] In the prior art, most printing machines are not equipped with automatic material receiving devices. After the woven bags are printed by the printing machine and output from the conveyor belt inside the printing machine, they often need to be manually stacked and carried to a collection box, which increases the workload of the staff. Utility Model Content

[0004] The utility model aims to provide an offset printing machine which does not require manual stacking by workers after printing, thereby greatly reducing the workload.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A offset printing machine comprises a conveyor belt, a printing assembly arranged above the conveyor belt, and a material receiving device arranged at the discharge end of the conveyor belt; the material receiving device comprises a collecting box, a placement plate slidably arranged in the collecting box, and a plurality of springs arranged between the collecting box and the placement plate.

[0007] Preferably, a side wall of the placement plate is provided with a sliding block, and an inner wall of the collection box is provided with a vertical sliding rail that slidably cooperates with the sliding block.

[0008] Preferably, a hydraulic rod is also provided in the middle of the inner bottom wall of the collecting box.

[0009] Preferably, the printing machine further comprises a binding belt detachably arranged in the collection box, and two ends of the binding belt are arranged outside the collection box.

[0020] Example 1

[0021] An offset printing machine, such as Figure 1As shown, it includes a conveyor belt 100, a printing assembly 110 arranged above the conveyor belt 100, and a material receiving device arranged at the discharge end of the conveyor belt 100; the transmission direction of the transmission belt is from left to right, and the transmission principle of the conveyor belt 100 is the existing technology, and its principle and the devices involved in the transmission process are not described in detail here; the printing assembly 110 is the existing technology, including a roller and a support frame for supporting the roller, and the printing principle of the roller is the existing technology, and its principle and other devices involved in the printing process, such as the device for driving the roller to rotate, are not described in detail here. In addition, the material receiving device includes a collection box 120, a placement plate 130 slidably arranged in the collection box 120, and a plurality of springs 140 arranged between the collection box 120 and the placement plate 130.

[0022] Working principle: The woven bags to be printed (not shown) are placed on the feeding end of the conveyor belt 100 (i.e., the left side of the conveyor belt 100). Under the conveying action of the conveyor belt 100, the woven bags are conveyed one by one to the bottom of the printing component 110. After being printed by the printing component 110, the woven bags slide from the discharging end of the conveyor belt 100 (i.e., the right side) onto the placement plate 130 in the collection box 120. Because there are few woven bags on the placement plate 130 initially, the weight of the placement plate 130 is relatively light at this time. Under the elastic action of the spring 140, the placement plate 130 is in the highest state. Subsequently, in the process of continuous collection of the woven bags, the weight of the woven bags on the top of the placement plate 130 gradually increases, thereby compressing the spring 140 and causing the placement plate 130 to slide down in the collection box 120. This ensures that the position where the woven bags fall in the collection box 120 is at a higher position, thereby reducing the falling height of the woven bags, effectively reducing the bending and folding of the woven bags during the falling process, thereby improving the overlapping degree of the woven bags and the flatness of the woven bags.

[0023] Through the synergistic effect of the above-mentioned devices, the staff does not need to manually overlap the printed woven bags and move them to the collection box 120 after overlapping, which can effectively reduce the workload and improve the collection efficiency.

[0024] Further, based on the embodiments, Figure 1-3 As shown, the side wall of the placement plate 130 is provided with a slider 150, and the inner wall of the collection box 120 is provided with a vertical slide rail 160 that slides with the slider 150. In order to improve the sliding stability of the placement plate 130, the number of the sliders 150 is at least 2. In this solution, by providing the slider 150 and the vertical slide rail 160, the smoothness of movement of the placement plate 130 can be improved, and the placement plate 130 can be limited to ensure that it always moves in the vertical direction.

[0025] Furthermore, in order to facilitate the removal of the woven bags collected in the collection box 120, as Figure 1 and Figure 2 As shown, a hydraulic rod 170 is also provided in the middle of the inner bottom wall of the collection box 120. When the woven bags in the collection box 120 are collected, the hydraulic rod 170 is activated to move the placement plate 130 upward and extend the spring 140 until the placement plate 130 moves upward to the top of the collection box 120. At this time, the staff can directly take away the collected woven bags.

[0026] Furthermore, since the woven bags in the collection box 120 are in an overlapping state and are not bound to each other, when the staff takes them, the woven bags are in a scattered state and are easy to fall when moving, thereby causing the woven bags to be scattered. Based on this, in order to prevent the woven bags from being scattered when the staff move them and to facilitate the staff to take them, Figure 1-3 As shown, the printing machine further includes a binding belt 180 detachably disposed in the collection box 120, and the two ends of the binding belt 180 are disposed outside the collection box 120. In specific implementation, before collecting the woven bags, the binding belt 180 is first placed on the top of the placement plate 130, and the two ends are placed outside the collection box 120. During the gradual collection process, the woven bags will press the binding belt 180 underneath, and during the gradual downward movement of the placement plate 130, the two ends of the binding belt 180 will be driven to move downward accordingly, thereby ensuring that all the woven bags are located within the binding belt 180, so that after the final collection is completed, the two free ends of the woven bags can be bound. Among them, in actual implementation, the number of binding belts 180 is not limited.

[0027] Furthermore, in order to limit the two free ends of the woven bag to minimize the degree of deflection, as Figure 2-4 As shown, the outer walls on both sides of the collection box 120 are provided with connecting rings 190, and the two ends of the binding belt 180 pass through the two connecting rings 190 from top to bottom. Furthermore, gravity balls are provided at both ends of the binding belt 180. By providing the gravity balls, the two ends of the binding belt 180 can be in a drooping state, and the vertical projections of the two free ends of the binding belt 180 and the vertical projections of the binding belt 180 located in the collection box 120 can be located in the same vertical plane to the greatest extent, thereby reducing the deviation of the binding belt 180 located on both sides of the woven bag during the downward movement of the placement plate 130, resulting in the need to sort out the binding belt 180 after the collection is completed, so that the binding belt 180 located on both sides of the woven bag is adjusted to a vertical state, which increases the workload. It is worth noting that the weight of the gravity ball is set mainly so as not to hinder the vertical displacement of the placement plate 130.

[0028] Furthermore, in order to reduce the inner ring size of the connecting ring 190, the deflection of the binding belt 180 can be minimized, and the binding belt 180 can be easily arranged in the connecting ring 190. Figure 2-4As shown, the side wall of the connecting ring 190 is provided with an opening, and a stopper 210 capable of automatically resetting is rotatably provided at one end of the opening, and the stopper 210 can close the connecting ring 190, and a return spring 220 is further provided between the stopper 210 and the connecting ring 190. In specific implementation, the stopper 210 is pressed inwardly to allow the binding belt 180 to be sent into the connecting ring 190 along the opening, and then released, and under the action of the return spring 220, the stopper 210 returns to its original position to close the opening.
