Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically a packaging machine with adjustable belt feeding. Background Technology

[0002] Nowadays, brick factories are increasingly using packaging machinery and equipment to replace manual labor. Brick packing has become an essential process in brick factories, and the brick packing machine is the most important piece of equipment used in this process. Within the packing head of the machine, the belt feeding mechanism is a crucial component. Currently, many brick packing machines use hydraulic motors to control the rotation of the belt feeding wheel, and most packing machines are equipped with a pre-tensioning chain.

[0003] Currently used strapping machines require the strapping tape to come out of the guide groove of the strapping head, pass through the pre-tension chain, and then enter the slot on the feed wheel before entering the unwinding position of the strapping head. However, due to the presence of the pre-tension chain, it takes a long time to pass the strapping tape through the slot on the feed wheel to avoid it getting stuck on the pre-tension chain, resulting in poor overall efficiency. Therefore, we propose a strapping machine with adjustable tape feeding. Utility Model Content

[0004] The purpose of this invention is to provide a packing machine with adjustable belt feeding to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable strapping machine, comprising a strapping machine body and a strapping mechanism disposed on the strapping machine body, the strapping mechanism comprising a servo motor and a strapping wheel, the surface of the strapping machine body being provided with a pre-tightening mechanism and a pulling assembly, the pre-tightening mechanism comprising a pre-tightening chain, a pre-tightening plate, a strapping frame and an adjusting component;

[0006] The pull-out component includes:

[0007] The pull rod is used to pull the preload chain so that it does not come into contact with the feed pulley when it is loosened.

[0008] The mounting bracket is used to support the tie rod;

[0009] Spring clips are used to control the movement of the lever.

[0010] Preferably, the servo motor is fixed to the back of the main body of the packing machine, and the output shaft of the servo motor passes through the main body of the packing machine and is fixed to the feeding wheel. The feeding operation is performed by driving the feeding wheel to rotate through the servo motor.

[0011] Preferably, the pre-tensioning chain is in contact with the surface of the feed wheel, a pre-tensioning plate is hinged to one end of the pre-tensioning chain, a strapping frame is fixed to the end of the pre-tensioning plate away from the pre-tensioning chain, the strapping frame is fixed to the surface of the main body of the strapping machine by bolts, and an adjustment component is provided at the other end of the pre-tensioning chain. The pre-tensioning chain is tightened by the adjustment component, so that the strapping in the middle between the pre-tensioning chain and the edge of the feed wheel can be pressed and adjusted according to the actual use, so as to achieve the function of adjustable strapping.

[0012] Preferably, the adjusting component includes a slide groove formed on the surface of the baling machine body. A bracket is slidably installed on the inner side of the slide groove. The bracket is hinged to the end of the pre-tensioned chain away from the pre-tensioning plate. An adjusting screw is provided on the bracket. A fixing plate is fixed to the surface of the baling machine body. The adjusting screw passes through the fixing plate and is rotatably connected to the fixing plate. The adjusting screw passes through the bracket and is threadedly connected to the bracket. By rotating the adjusting screw, the bracket can be controlled to move to the right or left, thereby controlling the pre-tensioned chain to be tightened or loosened.

[0013] Preferably, the fixing frame is fixed to the surface of the main body of the strapping machine, the pull rod is hinged to the inside of the fixing frame, a spring is fixed to the right side of the fixing frame, the end of the spring away from the fixing frame is fixed to the top of the pull rod, and the end of the pull rod away from the fixing frame is hinged to the pre-tension chain. The spring applies a downward swinging force to the pull rod. When the pre-tension chain is no longer taut, the pull rod can swing downward at the hinged position with the fixing frame under the action of the spring, and the pull rod can pull the pre-tension chain so that the pre-tension chain no longer keeps in contact with the feed wheel. At this time, the operator can easily pass the strapping tape through the groove of the feed wheel, which is convenient to use and effectively improves the overall work efficiency.

[0014] Compared with the prior art, this utility model provides a packing machine with adjustable belt feeding, which has the following features:

[0015] Beneficial effects:

[0016] 1. This adjustable strapping machine, through its pull-out component and pre-tightening mechanism, allows the pull rod to swing downwards at the hinged position with the fixed frame under the action of the spring plate after the pre-tightening chain is no longer taut. The pull rod then pulls the pre-tightening chain, causing it to no longer be in contact with the feed wheel. At this point, the operator can easily pass the strapping through the groove of the feed wheel, making it convenient to use and effectively improving overall work efficiency.

[0017] 2. This adjustable strapping machine allows the support to move to the right or left by rotating the adjusting screw, thereby controlling the tension or loosening of the pre-tension chain. This enables the strapping in the pre-tension chain and the edge of the feed wheel to be pressed and adjusted according to the actual usage, thus achieving the function of adjustable strapping.

[0022] like Figures 1-3 As shown, this utility model provides a technical solution: an adjustable strapping machine, including a strapping machine body 1 and a strapping mechanism 2 disposed on the strapping machine body 1. The strapping mechanism 2 includes a servo motor 21 and a strapping wheel 22. The surface of the strapping machine body 1 is provided with a pre-tightening mechanism 3 and a pulling assembly 4. The pre-tightening mechanism 3 is composed of a pre-tightening chain 31, a pre-tightening plate 32, a strapping frame 33 and an adjusting component 34. The pulling assembly 4 includes a pull rod 41, a fixing frame 42 and a spring piece 43.

[0023] The servo motor 21 is fixed to the back of the main body 1 of the packing machine. The output shaft of the servo motor 21 passes through the main body 1 of the packing machine and is fixed to the belt feeder 22. The belt feeder 22 is driven to rotate by the servo motor 21 to perform the belt feeding operation.

[0024] The pre-tension chain 31 is in contact with the surface of the feed roller 22. A pre-tension plate 32 is hinged to one end of the pre-tension chain 31. A strapping frame 33 is fixed to the end of the pre-tension plate 32 away from the pre-tension chain 31. The strapping frame 33 is fixed to the surface of the main body 1 of the packing machine by bolts. An adjusting member 34 is provided at the other end of the pre-tension chain 31. The pre-tension chain 31 is tightened by the adjusting member 34, so that the packing strap between the edge of the pre-tension chain 31 and the feed roller 22 can be pressed and adjusted according to the actual use, so as to achieve the function of adjustable strap feeding.

[0025] The adjusting component 34 includes a slide groove 341, which is formed on the surface of the main body 1 of the baling machine. A bracket 342 is slidably installed on the inner side of the slide groove 341. The bracket 342 is hinged to the end of the pre-tensioned chain 31 away from the pre-tensioning plate 32. An adjusting screw 343 is provided on the bracket 342. A fixing plate 344 is fixed on the surface of the main body 1 of the baling machine. The adjusting screw 343 passes through the fixing plate 344 and is rotatably connected to the fixing plate 344. The adjusting screw 343 passes through the bracket 342 and is threadedly connected to the bracket 342. By rotating the adjusting screw 343, the bracket 342 can be controlled to move to the right or left, thereby controlling the pre-tensioned chain 31 to be tightened or loosened.

[0026] The fixing frame 42 is fixed to the surface of the main body 1 of the packing machine. The pull rod 41 is hinged to the inside of the fixing frame 42. A spring piece 43 is fixed to the right side of the fixing frame 42. The end of the spring piece 43 away from the fixing frame 42 is fixed to the top of the pull rod 41. The end of the pull rod 41 away from the fixing frame 42 is hinged to the pre-tension chain 31. The spring piece 43 applies a downward swinging force to the pull rod 41. When the pre-tension chain 31 is no longer taut, the pull rod 41 can swing downward at the hinged position with the fixing frame 42 under the action of the spring piece 43. The pull rod 41 can then pull the pre-tension chain 31, so that the pre-tension chain 31 is no longer in contact with the feed wheel 22. At this time, the operator can easily pass the packing strap through the groove of the feed wheel 22. It is convenient to use and effectively improves the overall work efficiency.

[0027] In this invention, during use, the strapping is first threaded before packaging. The strapping emerges from the guide groove of the packaging head of the packaging machine body 1. At this time, the adjusting screw 343 is rotated, controlling the bracket 342 to move to the left. The bracket 342, along with the pre-tension chain 31, is released. The pull rod 41 can then pull the pre-tension chain 31, so that the pre-tension chain 31 is no longer in contact with the feed wheel 22. Next, the strapping continues to be threaded around the groove on the feed wheel 22, so that the strapping is below the pre-tension chain 31. Then, it is threaded along the feed wheel 22 into the strapping frame 33, and finally enters the strapping unwinding device in the packaging head of the packaging machine body 1. The strapping before packaging is completed.

[0028] Then, rotate the adjusting screw 343 in the opposite direction to move the control bracket 342 to the right, so that the pre-tensioned chain 31 is tightened, and the packing strap between the pre-tensioned chain 31 and the edge of the feed wheel 22 is pressed, which is convenient to operate.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
