Description

TECHNICAL FIELD

[0001] The present application relates to the field of packaging technology, in particular to a multi-size fixed-length packing belt automatic production device. BACKGROUND

[0002] For some air cylinder products, they are inflated before transportation and have passed inspection. Please refer to Figure 1 When transporting such air cylinder products, the piston needs to be pressed into the cylinder, and then a certain length of annular packing belt is tightened to reduce the transportation volume and increase the transportation capacity.

[0003] At present, annular packing belts are generally made on automatic packing machines, which include two specific methods:

[0004] 1. A circular paper tube with the same circumference as the required length is placed on the automatic packing machine. The annular packing belt is wound on the circular paper tube by the automatic packing machine until the packing belt covers the circular paper tube, and then the automatic packing machine is stopped. The packing belt on the circular paper tube is removed and then the annular packing belt is wound on the circular paper tube again.

[0005] 2. A rope is hung on the fixed frame of the automatic packing machine (the rope is sleeved on the fixed frame). The length of the rope controls the length of the packing belt. The annular packing belt is wound on the rope by the automatic packing machine until the rope is full of packing belts, and then the automatic packing machine is stopped. The packing belt on the rope is removed and then the packing belt is manufactured again.

[0006] Both of the above methods can manufacture multiple packing belts at a time, but have the following disadvantages:

[0007] 1. The packing belt needs to be removed after covering the circular paper tube or being full of packing belts, and then the manufacturing of the packing belt can continue. Therefore, the manufacturing process of the packing belt is time-consuming and laborious.

[0008] 2. As the packing belt is manufactured, the following packing belt will be wound outside the previous packing belt, causing the error of the following packing belt to gradually increase. If the manufacturing efficiency of the packing belt is pursued, the length of the packed air cylinder will be different, which is not easy to place. If the accuracy of the packing belt is pursued, the continuous working time of the automatic packing machine is short, which reduces the production efficiency of the packing belt. SUMMARY

[0009] The present application aims to provide a multi-size fixed-length packing belt automatic production device to solve the problem of time-consuming and laborious manufacturing of existing circular packing belts, and the incompatibility of accuracy and production efficiency.

The packaging machine 10 adopts an existing automatic packaging machine, and the specific structure and working mode of the packaging machine 10 will not be described here. The adjusting mechanism 20 is directly installed on the fixing frame 11 of the existing packaging machine 10, so that the automatic continuous production of the annular packaging belt can be realized, and the length has high precision, that is, the length of the same specification annular packaging belt produced changes little.

[0040] In order to facilitate the description of the embodiment, only part of the structure and operation process of the packaging machine 10 is described here. The top of the packaging machine 10 is provided with a fixing frame 11. When the packaging is not carried out, the packaging belt passes through the fixing frame 11. When the packaging is carried out, the packaging belt is stretched out from the fixing frame 11 and is gathered until the packaging belt is wound on the product or structure to be packaged. Finally, the heat sealer melts and breaks at the heat sealing point, and the two ends of the packaging belt are bonded together to complete the packaging operation.

[0041] Please refer to Figure 2 and Figure 3 The adjusting mechanism 20 comprises a mounting frame 21 connected to the fixing frame 11, a suspension rod 22 connected to the mounting frame 21, a sliding rail 23 connected to the bottom end of the suspension rod 22, and a first support 31 and a second support 32 connected to the sliding rail 23. The first support 31 and the second support 32 are located on the inner side of the fixing frame 11. When the packaging belt is gathered, the packaging belt will be hung on the first support 31 and the second support 32. Then, the packaging belt is melted and broken at the heat melting point of the heat sealer. After the two ends of the packaging belt are bonded, the annular packaging belt is formed and bounces off the first support 31 and the second support 32.

[0042] The mounting frame 21 comprises a clamping block 24 and a supporting block 25. The clamping block 24 is in a U shape and is clamped on the top of the fixing frame 11. The supporting block 25 is in an L shape, one end of which is fixedly connected to the top of the clamping block 24, and the other end is in a free state. In the embodiment, the clamping block 24 is also connected to the fixing frame 11 by a bolt.

[0043] The suspension rod 22 is vertically arranged and comprises a threaded section and a smooth rod section. The threaded section passes through the supporting block 25 from bottom to top and is connected with a nut. The height of the suspension rod 22 is adjusted by adjusting the nut. The smooth rod section is connected with the sliding rail 23. In the embodiment, in order to ensure that the suspension rod 22 slides in the vertical direction, the clamping block 24 is provided with a guide block 26, and the smooth rod section slides through the guide block 26.

[0044] The sliding rail 23 is horizontally arranged, that is, the sliding rail 23 is vertically arranged with the suspension rod 22, and the sliding rail 23 is parallel to the fixing frame 11, so that the packaging belt will not interfere with the sliding rail 23 when the packaging belt is gathered. The sliding rail 23 is provided with scales, the 0 scale line of which corresponds to the heat sealing point of the heat sealer, and the two sides of the 0 scale line are also provided with scales.

[0045] The first support 31 and the second support 32 are identical in structure, and are arranged on the same side of the slide rail 23, and the first support 31 and the second support 32 are arranged in parallel on the two sides of the 0 scale line.

[0046] Please refer to Figure 4 The first support 31 comprises a sliding block 33, a support rod 34, a limiting rod 35 and a rotating rod 36. The sliding block 33 is sleeved on the slide rail 23 and is in sliding fit with the slide rail 23, and the sliding block 33 is connected with the slide rail 23 by a bolt, for fixing the position of the sliding block 33. The support rod 34 is arranged horizontally, one end of which is connected with the sliding block 33 and the limiting rod 35, and the limiting rod 35 is located at the top of the support rod 34 and is parallel to the support rod 34. The middle part of the rotating rod 36 is hinged to the other end of the support rod 34, one end of the rotating rod 36 is provided with a weight 37, and the other end of the rotating rod 36 is located between the limiting rod 35 and the support rod 34. When the packing belt is not produced, the rotating rod 36 is in contact with the limiting rod 35, and when the packing belt is produced, the rotating rod 36 is in contact with the support rod 34 under the action of tension. After the production of the packing belt is completed, the rotating rod 36 rotates under the action of the weight, and guides the annular packing belt to pop out outward.

[0047] Please refer to Figure 5 The use process of the multi-size fixed-length packing belt automatic production device in this embodiment is as follows:

[0048] (1) Adjust the sliding blocks of the first support 31 and the second support 32, and after adjusting the first support 31 and the second support 32 to the set position, fix them on the slide rail 23 by a bolt, and screw the nut to make the suspension rod 22 located at the set position;

[0049] (2) Start the packing machine 10, so that the packing belt is gathered and contacts the rotating rod 36. After the rotating rod 36 is stressed, it rotates until it contacts the support rod 34, at which time the packing belt bears tension;

[0050] (3) The heat sealer of the packing machine 10 works, and the packing belt is melted and cut at the hot melting point, and the two ends of the packing belt are bonded together to form an annular packing belt. The annular packing belt pops up under the action of the reaction force;

[0051] (4) The rotating rod 36 rotates under the action of the weight 37, and in the rotating process, it can guide the annular packing belt to pop out outward, realizing the automatic production of the annular packing belt. After the rotating rod 36 finishes rotating, it contacts the limiting rod 35, at which time the rotating rod 36 is in an inclined state. Even if the packing belt does not pop out, it can also slide down from the rotating rod 36, avoiding that the annular packing belt stays on the rotating rod 36;

[0052] (5) Detect the length of the annular packing belt. If there is a deviation between the measured length and the designed length, adjust the height of the suspension rod 22 by adjusting the nut;

[0053] (6) repeating steps (2) to (5) until the length of the produced endless packing belt is within the qualified range;

[0054] (7) repeating steps (2) to (4) to continuously produce qualified endless packing belts.

[0055] The multi-size fixed-length packing belt automatic production device of the embodiment can realize automatic continuous manufacturing of endless packing belts without stopping the packing machine when producing endless packing belts, and the endless packing belts do not interfere with each other, so that the length accuracy of all endless packing belts is high. In addition, the first support 31 and the second support 32 for the ejection of the endless packing belt are pure mechanical structures, which are simple in structure, low in cost, and high in reliability.

[0056] The above description is only the preferred embodiment of the present application, and is not intended to limit the present application.
