Description

Technical Field

[0001] This utility model relates to the field of printing press component technology, and in particular to a baffle adjustment mechanism for the leading edge paper feeding section of a printing press. Background Technology

[0002] The front edge feeding section of a printing press is equipped with a pair of front baffles and a pair of side baffles to ensure neat paper feeding. Depending on the size of the carton, the front baffles and side baffles need to be adjusted. The baffle adjustment mechanism of the front edge feeding section of the printing press is an auxiliary device used to adjust the spacing between the pair of front baffles and the pair of side baffles, and it is widely used in the field of packaging machinery.

[0003] In existing printing presses, the pair of side baffles on the front edge paper feeding section are adjusted by a motor and a lead screw. The front baffle is usually fixed to the frame plate with bolts. When adjusting the front baffle, it is necessary to remove it and change its position for adjustment. This method is time-consuming and the efficiency of disassembly and replacement is low. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the front baffle is usually fixed to the frame plate with bolts. When adjusting the front baffle, it is necessary to remove the front baffle and change its position. This method is time-consuming and has low efficiency in disassembly and replacement. Therefore, a baffle adjustment mechanism for the front edge paper feeding part of the printing press is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a baffle adjustment mechanism for the front edge paper feeding section of a printing press, comprising a frame rod, a motor disposed on one side of the outer surface of the frame rod, a lead screw fixedly connected to the output end of the motor, the outer surface of the lead screw being provided with threads in opposite directions, one end of the lead screw rotating on one side of the frame rod, a plurality of sliding grooves being provided on one side of the frame rod, two side baffles being slidably connected to one side of the frame rod, one side of the inner wall of the side baffle being threadedly connected to the outer surface of the lead screw, the outer surface portion of the side baffle sliding on the inner wall of the sliding groove, two front baffles being slidably connected to one side of the frame rod, and an adjustment device being provided at the top of the front baffles for facilitating adjustment and fixing of the position of the front baffles.

[0006] The effect achieved by the above components is that the operation motor drives the lead screw to rotate, which can control the two side baffles to slide and adjust the position of the side baffles at both ends of the outer surface of the lead screw and one side of the support rod.

[0007] Preferably, the adjusting device includes a grooved rod, the bottom end of which is fixedly connected to the top end of a support rod. A T-shaped groove is formed inside the grooved rod, and several scale strips are provided on one side of the grooved rod. An L-shaped rod is fixedly connected to the top end of the front baffle. One end of the L-shaped rod slides on the inner wall of the T-shaped groove with the aid of a positioning component. A screw is threadedly connected to one side of the inner wall of the L-shaped rod, and an L-shaped block is rotatably connected to one end of the screw. One end of the L-shaped block slides on one side of the L-shaped rod.

[0008] The effect achieved by the above components is as follows: When the position of the front baffle needs to be adjusted, push the two front baffles on one side of the support rod to control the front baffles to slide in the T-groove inside the groove rod through the positioning component at one end of the L-shaped rod to adjust the horizontal position of the front baffles. Observe and judge whether the positions of the two front baffles are consistent according to the scale strip on one side of the groove rod. After the adjustment is completed, turn the screw at the L-shaped rod at the top of the two front baffles to control the screw to move towards the groove rod on the inner wall of the L-shaped rod, push one end of the L-shaped block to slide on one side of the L-shaped rod, press one side of the L-shaped block tightly against the side of the groove rod with the scale strip, and fix the position of the front baffle at the front end of the support rod.

[0009] Preferably, a plurality of rectangular strips are fixedly connected to one side of the L-shaped block, the rectangular strips being linearly distributed on one side of the L-shaped block, and the rectangular strips being made of rubber.

[0010] The effect achieved by the above components is that when the side of the L-shaped block with the rubber rectangular strip is pressed against the outer surface of the groove rod to fix the L-shaped rod, it is more stable and less prone to slippage.

[0011] Preferably, one end of the screw is fixedly connected to an operating block, and the outer surface of the operating block is provided with several protrusions.

[0012] The effect achieved by the above components is that the protrusion on the outer surface of the operating block makes it easier to rotate the operating block to control the screw rotation and adjust the position of the L-shaped block.

[0013] Preferably, one end of the L-shaped rod is provided with a positioning component, the positioning component including a bolt, the outer surface of the bolt being threaded to one end of the inner wall of the L-shaped rod, one end of the bolt being rotatably connected to a pressure block, one end of the L-shaped rod having a rectangular groove, the pressure block sliding on the inner wall of the rectangular groove, and two magnetic blocks with opposite magnetic properties slidingly connected to the bottom end of the inner wall of the rectangular groove, the edges of the two magnetic blocks that are close to each other being beveled.

[0014] The effect achieved by the above components is as follows: when the pressure block is located inside the rectangular groove near the top, the two magnetic blocks will not protrude from the inside of the rectangular groove due to their attraction at one end. At this time, one end of the L-shaped rod can be inserted into the T-shaped groove inside the groove rod. Then, by rotating the bolt, the pressure block is lowered so that its bottom end enters between the two magnetic blocks and pushes the two magnetic blocks away from each other and protruding from the inside of the rectangular groove. This restricts the position of one end of the L-shaped rod inside the T-shaped groove. Pushing the L-shaped rod can control one end of the L-shaped rod and one end of the two magnetic blocks to slide on the inner wall of the T-shaped groove. When the front baffle needs to be removed, rotating the bolt will raise the pressure block, and the two magnetic blocks will attract each other and move closer to each other into the rectangular groove. At this time, the L-shaped rod can be pulled upward to remove the L-shaped rod and the front baffle.

[0015] Preferably, a positioning device is provided on the outer surface of the L-shaped rod near the end of the groove rod. The positioning device includes a round rod, a rectangular block is fixedly connected to the top end of the round rod, and two elastic metal plates are fixedly connected to the bottom end of the rectangular block. The bottom end of the round rod is rotatably connected to the outer surface of the L-shaped rod.

[0016] The effect achieved by the above components is as follows: after one end of the L-shaped rod is inserted into the T-shaped groove and fixed by the positioning component, the rectangular block can be pushed to rotate through the round rod so that the rectangular block is located at the top of the bolt. When an elastic metal piece at the bottom of the rectangular block contacts the top of the bolt, it will bend. When the rectangular block is above the bolt, the elastic metal piece will return to its original shape, so that the rectangular block is located at the top of the bolt. The two elastic metal pieces located on both sides of the top of the bolt can protect the outside of the bolt and further restrict the position of the bolt, so as to avoid the bolt loosening from affecting the stability of the positioning component in restricting the position of one end of the L-shaped rod inside the groove.

[0017] Preferably, a groove block is fixedly connected to the top of the rectangular block, and two grooves are formed on the outer surface of the groove block.

[0018] The effect achieved by the above components is that pinching the two grooves on the outer surface of the block makes it easier to control the rectangular block to rotate through the round rod.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, by setting an adjustment device, the position of the front baffle is adjusted by pushing the front baffle so that one end of the L-shaped rod slides on the inner wall of the groove rod. The position of the front baffle can be easily observed through the scale strip on one side of the groove rod. By rotating the screw to control the movement of the L-shaped block and pressing one side of it against the side of the groove rod, the position of the front baffle can be fixed. There is no need to remove the front baffle to change its position, which improves the flexibility and convenience of the adjustment mechanism. Attached Figure Description

A screw 24 is threadedly connected to one side of the inner wall of the L-shaped rod 23. An L-shaped block 25 is rotatably connected to one end of the screw 24. One end of the L-shaped block 25 slides on one side of the L-shaped rod 23. When it is necessary to adjust the position of the front baffle 8, the two front baffles 8 are pushed on one side of the support rod 1 to control the front baffles 8 to slide in the T-shaped groove 22 inside the grooved rod 21 through the positioning component 28 at one end of the L-shaped rod 23 to adjust the horizontal position of the front baffles 8. The two front baffles are observed and judged according to the scale strips on one side of the grooved rod 21. After adjusting the positions of the front baffles 8, rotate the screw 24 at the L-shaped rod 23 at the top of each of the two front baffles 8 to move the screw 24 towards the groove rod 21 on the inner wall of the L-shaped rod 23. This pushes one end of the L-shaped block 25 to slide on one side of the L-shaped rod 23, pressing one side of the L-shaped block 25 against the side of the groove rod 21 with the scale strip. This fixes the front baffle 8 at the front end of the support rod 1. By setting the adjustment device 2, the position of the front baffle 8 can be adjusted by pushing the front baffle 8 so that one end of the L-shaped rod 23 slides on the inner wall of the groove rod 21. The position of the front baffle 8 can be easily observed through the scale strip on one side of the groove rod 21. Rotating the screw 24 controls the L-shaped block 25 to move and press one side against the side of the groove rod 21 to fix the position of the front baffle 8. It is not necessary to remove the front baffle 8 to change its position, which improves the flexibility and convenience of the adjustment mechanism.

[0029] Reference Figure 2-4 As shown in this embodiment: a number of rectangular strips 26 are fixedly connected to one side of the L-shaped block 25. The rectangular strips 26 are linearly distributed on one side of the L-shaped block 25. The rectangular strips 26 are made of rubber. When the side of the L-shaped block 25 with the rubber rectangular strips 26 is pressed against the outer surface of the groove rod 21 to fix the L-shaped rod 23, it is more stable and less prone to slippage. One end of the screw 24 is fixedly connected to an operating block 27. The outer surface of the operating block 27 is provided with a number of protrusions. Holding the protrusions on the outer surface of the operating block 27 makes it easier to rotate the operating block 27 to control the screw 24 to rotate and adjust the position of the L-shaped block 25.

[0030] Reference Figure 2-4As shown in this embodiment: one end of the L-shaped rod 23 is provided with a positioning component 28 that can restrict the position of one end of the L-shaped rod 23 inside the groove rod 21. The positioning component 28 includes a bolt 281. The outer surface of the bolt 281 is threaded to one end of the inner wall of the L-shaped rod 23. One end of the bolt 281 is rotatably connected to a pressure block 283. A rectangular groove 282 is opened at one end of the L-shaped rod 23. The pressure block 283 slides on the inner wall of the rectangular groove 282. Two magnetic blocks 284 with opposite magnetic properties are slidably connected to the bottom end of the inner wall of the rectangular groove 282. The edges of the two magnetic blocks 284 that are close to each other are inclined. When the pressure block 283 is located inside the rectangular groove 282 near the top, the two magnetic blocks 284 attract each other and will not protrude from the inside of the rectangular groove 282. At this point, one end of the L-shaped rod 23 can be inserted into the T-shaped groove 22 inside the groove rod 21. Then, rotate the bolt 281 to control the bolt 281 to drive the pressure block 283 down so that the bottom end of the pressure block 283 enters between the two magnetic blocks 284 and pushes the two magnetic blocks 284 away from each other and protruding into the rectangular groove 282. This can restrict the position of one end of the L-shaped rod 23 inside the T-shaped groove 22. Pushing the L-shaped rod 23 can control one end of the L-shaped rod 23 and one end of the two magnetic blocks 284 to slide on the inner wall of the T-shaped groove 22. When the front baffle 8 needs to be removed, rotate the bolt 281 to drive the pressure block 283 up. The two magnetic blocks 284 will attract each other and move closer to each other into the rectangular groove 282. At this time, pull the L-shaped rod 23 upward to remove the L-shaped rod 23 and the front baffle 8.

[0031] Reference Figure 1 , Figure 4 and Figure 5 As shown in this embodiment: a positioning device 3 is provided at one end of the outer surface of the L-shaped rod 23 near the groove rod 21. The positioning device 3 includes a round rod 31, a rectangular block 32 is fixedly connected to the top end of the round rod 31, and two elastic metal pieces 33 are fixedly connected to the bottom end of the rectangular block 32. The bottom end of the round rod 31 is rotatably connected to the outer surface of the L-shaped rod 23. After one end of the L-shaped rod 23 is inserted into the T-groove 22 and fixed by the positioning component 28, the rectangular block 32 can be pushed to rotate through the round rod 31 so that the rectangular block 32 is located at the top end of the bolt 281. When one of the elastic metal pieces 33 at the bottom end of the rectangular block 32 contacts the top end of the bolt 281, it will bend. When the rectangular block After the rectangular block 32 is positioned above the bolt 281, the elastic metal sheet 33 will return to its original shape, so that the rectangular block 32 is located at the top of the bolt 281. The two elastic metal sheets 33 located on both sides of the top of the bolt 281 can protect the outside of the bolt 281 and further restrict the position of the bolt 281, so as to avoid the bolt 281 from loosening and affecting the stability of the positioning component 28 in restricting the position of one end of the L-shaped rod 23 inside the groove rod 21. The top of the rectangular block 32 is fixedly connected to the groove block 34. Two grooves are opened on the outer surface of the groove block 34.
