[0002] Carton feeding equipment is a key component of automated packaging and logistics systems, mainly used to efficiently and smoothly transport cartons or cardboard to designated workstations. It typically consists of a power drive unit (such as a motor), a conveyor belt or roller mechanism, a guiding and positioning device, and a control system. Through continuous or intermittent movement, it transfers cartons from upstream equipment to downstream stages, improving production line efficiency.

[0003] However, some existing cardboard feeding equipment still has some shortcomings in actual use. For example, since the feeding components of some cardboard feeding equipment transport the cardboard raw materials via conveyor belts, they mainly rely on the friction between the belt and the rollers, which may result in slight elastic expansion or slippage. After prolonged use, these minor errors accumulate, leading to inaccurate paper feeding positions and affecting the stability of the entire production process and the product qualification rate.

[0027] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0028] As attached Figure 1 To be continued Figure 5 An embodiment of this utility model provides a paper feeding device for a chain baffle paper feeding equipment, including...

[0029] The base 1 has two bases. Side brackets 2 are fixedly installed on the two ends and the middle of the two bases 1 that are close to each other. A fixing bracket 3 is fixedly installed on the right side of the side bracket 2 located at the right end of the base 1.

[0030] The paper feeding main frame 4 has three paper feeding main frames in the middle of the two bases 1. The top of each of the three paper feeding main frames 4 is fixedly installed with a top plate 5. Several guide wheels 6 are rotatably installed on the inner surface of the junction between the top plate 5 and the paper feeding main frame 4.

[0031] Paper feeding mechanism 7 is located on the top of paper feeding main frame 4 and on the side away from guide wheel 6;

[0032] The coupling mechanism 8 is located at the top right end of the paper feeding main frame 4;

[0033] The drive motor 11 is fixedly mounted on the surface of the fixed frame 3, and the output end is fixedly mounted with a drive pulley.

[0034] The paper feeding mechanism 7 includes a paper feeding chain 70 and a nylon component 75. Both ends of the paper feeding chain 70 are engaged with paper feeding sprockets 71. Several chain blocks 72 are fixedly installed on the side surface of the paper feeding sprockets 71 at equal intervals. A baffle 73 is fixedly installed on the surface of the chain block 72 near the end of the coupling mechanism 8. The nylon component 75 is fixedly installed on the side of the top of the paper feeding main frame 4 away from the guide wheel 6. A guide plate fixing plate 74 is fixedly installed on the upper surface of the nylon component 75. The middle part of the guide plate fixing plate 74 is movably installed with the outer surface of the paper feeding chain 70. The guide plate fixing plate 74 is made of steel.

[0035] The coupling mechanism 8 includes a drive shaft 80 and a connecting seat 81. Both ends of the drive shaft 80 are rotatably mounted with mounting seats 82. The two mounting seats 82 are respectively fixedly mounted on the close surfaces of the top of the two fixed frames 3. The end of the drive shaft 80 is fixedly connected with a driven pulley 83. The outer surface of the driven pulley 83 is connected to the drive pulley at the output end of the drive motor 11 via a synchronous belt. The connecting seat 81 is rotatably mounted on the inner surface of the paper feeding frame 4.

[0036] The paper feeding sprocket 71 has an alignment groove 84 in the middle, which is slidably sleeved on the outer surface of the drive shaft 80. The paper feeding sprocket 71 is fixedly installed on the side of the connecting seat 81.

[0037] Among them, the middle of the two opposing side supports 2 is provided with a support adjustment mechanism 9, which includes a lead screw 93, and the top of the left end of the paper feeding main frame 4 is provided with a tensioning mechanism 10.

[0038] The bracket adjustment mechanism 9 includes an adjustment motor 90 and a bearing 94. There are two adjustment motors 90, which are fixedly installed on the surfaces of two fixed frames 3 respectively. An adjustment sprocket 91 is fixedly installed at the output end of the adjustment motor 90. Three lead screws 93 are provided on the paper feeding main frame 4 on both sides. The ends of the three lead screws 93 are rotatably installed with the two ends and the inner surface of the middle of the paper feeding main frame 4 located in the middle through the bearing 94. Driven sprockets 92 are fixedly installed at the ends of the three lead screws 93. The three driven sprockets 92 and the adjustment sprockets 91 are connected by a transmission chain. A slide rail 96 is provided below the lead screw 93. The two ends of the slide rail 96 are fixedly installed with the surfaces of the two bases 1. A slider 97 is slidably installed on the top of the slide rail 96. A connecting plate 98 is fixedly installed on the upper surface of the slider 97. The inner surface of the connecting plate 98 is threadedly connected to the inner surface of the end of the lead screw 93. An adjustment plate 95 is fixedly installed on the surface of the paper feeding main frame 4 on both sides.

[0039] By setting up the bracket adjustment mechanism 9, the adjustment motor 90 can drive the adjustment sprocket 91 connected to the output end to rotate. Furthermore, the meshing transmission chain pulls the driven sprockets 92 at the ends of three lead screws 93 located at the front, middle, and rear of the paper feeding main frame 4. The rotation of the driven sprockets 92 drives the connected lead screws 93 to rotate along the inner surface of the side brackets 2 on both sides, and along the inner surface of the bearings 94 fixed in the middle of the paper feeding main frame 4. The rotation of the lead screws 93 on the two sides of the paper feeding main frame 4 drives the adjustment plates 95 threaded to their outer surfaces to rotate. By moving closer to or further away from the paper feeding main frame 4, the paper feeding main frame 4 drives the connecting plate 98 and the slider 97 to slide along the outer surface of the slide rail 96. This allows adjustment of the position of the paper feeding main frames 4 on both sides. By adjusting the sprocket 91, driven sprocket 92 and other structures, the front, middle and rear adjustments of the paper feeding main frame 4 can be made more synchronized. This allows the movable paper feeding main frames 4 on both sides to be adjusted closer to or further away from the fixed paper feeding main frame 4 in the middle, depending on the specifications of the paperboard being transported. This adjusts the overall paper feeding width specifications, enhancing the flexibility of the device and the diversity of production and processing specifications.

[0040] By setting lead screws 93, lead screws 93 are set at both ends and the middle of the paper feeding main frame 4 on both sides, and the three lead screws 93 on the same side are of the same specification. The adjustment motor 90 and the adjustment sprocket 91 on the fixed frame 3 on the same side are used for synchronous adjustment and drive, so that the paper feeding main frame 4 on both sides can move closer to or further away from the paper feeding main frame 4 in the middle.

[0041] The tensioning mechanism 10 includes a sliding plate 100, a first sliding groove 104, and a second sliding groove 105. A paper feeding sprocket 71 is rotatably mounted on one side of the sliding plate 100, and an adjusting block 101 is fixedly mounted in the middle of the other side. The first sliding groove 104 is opened on the inner surface of the end of the paper feeding main frame 4, and the second sliding groove 105 is opened on the inner surface of the end of the paper feeding main frame 4. The outer surface of the adjusting block 101 is slidably mounted with the inner surface of the first sliding groove 104. A threaded rod 102 is threadedly connected to the inner surface of the adjusting block 101. The outer surface of the threaded rod 102 is rotatably mounted with the inner surface of the paper feeding main frame 4. Bolts 103 are threadedly connected to the inner surfaces of the four corners of the sliding plate 100.

[0042] By setting the tensioning mechanism 10, when installing the paper feeding chain 70, it can first be installed on the outside of the two paper feeding sprockets 71 located on the connecting seat 81 and the sliding plate 100. Then, the threaded rod 102 is adjusted to rotate along the inner surface of the paper feeding main frame 4, so that the threaded adjustment block 101 drives the sliding plate 100 to move against the surface of the paper feeding main frame 4 and the sliding groove 104 opened on it. During this process, the meshing effect of the paper feeding sprockets 71 and the paper feeding chain 70 can be continuously adjusted until the paper feeding chain 70 is at a suitable tension. Finally, the four corners of the sliding plate 100 are further locked to the paper feeding main frame 4 with bolts 103, which facilitates the installation or maintenance of the paper feeding chain 70, paper feeding sprockets 71 and other structures.

[0043] The working process of this utility model is as follows:

[0044] When feeding paperboard, it can be loaded onto the top plate 5 located at the top of the main feeding frame 4, and its side edge is then aligned with the surface of the baffle 73. Next, the drive motor 11 is controlled to drive the output pulley to rotate, which in turn drives the driven pulley 83 to rotate. This causes the connected drive shaft 80 to rotate along the inner surface of the mounting seats 82 at both ends, further driving the connecting seat 81 and the paper feeding sprocket 71, which are slidably fitted onto the outside of the drive shaft 80 and have an alignment groove 84 in the middle, to rotate. The rotation of the paper feeding sprocket 71 pulls the meshing paper feeding chain 70 along... The paper feed chain 70 moves within the groove of the nylon part 75, causing the paper feed sprocket 71, which is mounted on the tensioning mechanism 10 at the other end, to rotate. This causes the chain block 72 mounted on the surface of the paper feed chain 70 to move the baffle 73. The baffle 73 can push the paperboard to move, thereby achieving the paper feeding process. Typically, the precise meshing between the paper feed chain 70 and the paper feed sprocket 71 allows the baffles 73, which are equidistantly arranged on them, to achieve a forced mechanical synchronous pushing effect with the paperboard. This prevents the paperboard from slipping during the conveying process, making the position more accurate and facilitating the positioning processing needs.
