Description

Technical Field

[0001] This application relates to the field of printing equipment, and in particular to printing rods for printing equipment. Background Technology

[0002] In the printing process of plastic tubing, the tubing is usually fitted onto a printing rod, which is mounted on a printing press. A motor drives the printing rod to rotate around the turntable of the printing press, passing through each printing unit in sequence, thus completing the printing of the circumference of the tubing surface fitted onto the printing rod.

[0003] The utility model patent with announcement number CN207257093U proposes a printing rod for printing equipment, including a hollow cylindrical body and a heating device. The hollow cylindrical body includes a left hollow cylindrical body and a right hollow cylindrical body. The left hollow cylindrical body, the right hollow cylindrical body and the baffle are integrated into one piece. The heating device includes a frustum-shaped heat-conducting cavity and a heating tube located inside the heat-conducting cavity. A heat-conducting plate is installed on the side wall of the heat-conducting cavity. The inner wall of the right hollow cylindrical body is provided with several strip grooves parallel to the right hollow cylindrical body. The thickness between the bottom of the strip groove and the outer wall of the right hollow cylindrical body is 0.5-1mm. A condenser tube is installed in the strip groove.

[0004] The printing rod in one of the above-mentioned printing devices heats a plastic tube using the principle of thermal expansion and contraction, causing the plastic tube to expand and then fit onto the right hollow cylinder. The plastic tube is then cooled to shrink and tightly adhere to the outer wall of the right hollow cylinder. However, the heating and cooling process of the plastic tube can easily cause the material to age, resulting in a reduction in the durability of the plastic tube. Utility Model Content

[0005] To address the aforementioned problems, this application provides a printing rod for printing equipment.

[0006] The printing rod for printing equipment provided in this application adopts the following technical solution:

[0007] A printing rod for printing equipment includes a printing rod body. The printing rod body is provided with an abutment assembly for fixing a plastic tube. The abutment assembly includes four arc-shaped abutment plates arranged in a ring array on the side wall of the printing rod body. A plurality of equidistant positioning rods are fixedly connected to one side wall of the arc-shaped abutment plates. The other ends of the positioning rods are all located inside the printing rod body. Four sets of ring-shaped fixing rods are fixedly connected to both ends of the inner side wall of the printing rod body. A first moving plate and a second moving plate are sleeved on each set of fixing rods. A spring is fixedly connected between the first moving plate and the second moving plate. A push rod is fixedly connected to the side wall of the second moving plate away from the first moving plate. The other end of the push rod passes through the printing rod body and abuts against the arc-shaped abutment plates. The printing rod body is provided with a push assembly for pushing the first moving plate.

[0008] By adopting the above technical solution, in use, the plastic hose is sleeved on four arc-shaped abutment plates. Then, the first moving plate is pushed by the pushing component, which in turn pushes the second moving plate through a spring, causing the push rod to move. The push rod pushes the arc-shaped abutment plates away from the printing rod body, so that the arc-shaped abutment plates abut against the plastic hose, thus fixing the plastic hose. This avoids the problem of heating and cooling the plastic hose, which can easily cause material aging and reduce the durability of the plastic hose.

[0009] Preferably, the pushing assembly includes two connecting discs that are threaded to both ends of the printing rod body, and a cross pusher block is rotatably connected to one side wall of the connecting disc, and the four side walls of the cross pusher block abut against the first moving plate.

[0010] By adopting the above technical solution, the cross pusher is inserted into the printing rod body, pushing the first moving plate to move. With the help of the spring, after the pusher rod abuts against the arc-shaped abutment plate, the spring contracts, and after the arc-shaped abutment plate abuts against the plastic hose, the cross pusher can be fixed by rotating the connecting plate to make the connecting plate threadedly connected to the printing rod body.

[0011] Preferably, the end of the cross-shaped pusher block furthest from the connecting disc is tapered.

[0012] By adopting the above technical solution, the cone-shaped cross pusher can be easily inserted between the four first moving plates to push the first moving plates.

[0013] Preferably, the springs are respectively sleeved on the fixed rod.

[0014] By adopting the above technical solution, the stability of the spring can be improved by using a fixing rod, preventing the spring from bending when it contracts, which would affect the service life of the spring.

[0015] Preferably, a connecting plate is provided at both ends of the printing rod body, and a connecting rod is fixedly connected to both ends of one side wall of the connecting plate. The end of the connecting rod away from the connecting plate is fixedly connected to the printing rod body, and a connector for connecting to printing equipment is fixedly connected to the side wall of the connecting plate away from the connecting rod.

[0016] By adopting the above technical solution, the printing rod body can be easily rotated by connecting it to the printing equipment through the connector, and with the help of the connecting plate and connecting rod.

[0017] Preferably, a first limiting plate is fixedly connected to the end of the positioning rod away from the arc-shaped abutment plate, and a second limiting plate is fixedly connected to the end of the fixing rod away from the printing rod body.

[0018] By adopting the above technical solution, the first limiting plate can prevent the positioning rod from sliding out of the printing rod body, causing the arc-shaped abutment plate to fall off, and the second limiting plate can prevent the first moving plate and the second moving plate from falling off the fixed rod.

[0019] Preferably, annular limiting baffles are fixedly connected to both ends of the printing rod body on one side of the fixing rod, and the annular limiting baffles abut against the connecting plate.

[0020] By adopting the above technical solution, when the connecting disc is threaded to the printing rod body, the connecting disc abuts against the annular limiting baffle, which can limit the distance the connecting disc is screwed into the printing rod body and prevent the connecting disc from contacting the fixing rod.

[0021] Preferably, a rotating disk is fixedly connected to the end of the connecting disk away from the printing rod body.

[0022] By adopting the above technical solution, the connecting plate can be easily rotated by the rotating disk, allowing for the assembly and disassembly of the connecting plate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This application utilizes the coordinated arrangement of structures such as arc-shaped abutment plates, fixing rods, and push rods. In use, the plastic hose is sleeved on four arc-shaped abutment plates. Then, the first moving plate is pushed by the pushing component, causing the first moving plate to push the second moving plate via a spring. This causes the push rod to move, pushing the arc-shaped abutment plates away from the printing rod body, allowing the arc-shaped abutment plates to abut against the plastic hose and fix the plastic hose. This minimizes the need for heating and cooling the plastic hose, which can easily cause material aging and reduce the durability of the plastic hose.

[0025] 2. When threading the connecting disc to the printing rod body, the connecting disc should abut against the annular limiting baffle to limit the distance the connecting disc is screwed into the printing rod body and prevent the connecting disc from contacting the fixing rod.

[0031] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0032] This application discloses printing rods for printing equipment.

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A printing rod for printing equipment includes a printing rod body 1. The printing rod body 1 is provided with an abutment assembly for fixing a plastic hose. The abutment assembly includes an arc-shaped abutment plate 2, a positioning rod 3, a fixing rod 4, a first moving plate 5, a second moving plate 6, a spring 7, and a push rod 8.

[0034] Four arc-shaped abutment plates 2 are arranged in a circular array on the side wall of the printing rod body 1. Multiple sets of positioning rods 3 are arranged, with multiple rods in each set and equidistant from each other. Each set of positioning rods 3 is fixedly connected to one side wall of the arc-shaped abutment plate 2. The other end of each positioning rod 3 is located inside the printing rod body 1 and is slidably arranged. Eight sets of fixing rods 4 are arranged, with two rods in each set. The fixing rods 4 are fixedly connected to both ends of the inner side wall of the printing rod body 1 and are arranged in a circular array. Multiple first moving plates 5 and second moving plates 6 are arranged and respectively sleeved on each set of fixing rods 4. Multiple springs 7 are arranged and respectively located between the first moving plate 5 and the second moving plate 6 and are fixedly connected. Multiple push rods 8 are arranged and respectively fixedly connected to the side wall of the second moving plate 6 away from the first moving plate 5. The other end of the push rod 8 passes through the printing rod body 1 and abuts against the arc-shaped abutment plates 2. The printing rod body 1 is provided with a pushing component for pushing the first moving plate 5.

[0035] Reference Figure 1 and Figure 2The pushing component includes two connecting discs 9 that are threaded to both ends of the printing rod body 1. A cross pusher 10 is rotatably connected to one side wall of the connecting disc 9. The four side walls of the cross pusher 10 abut against the first moving plate 5. By inserting the cross pusher 10 into the printing rod body 1, the first moving plate 5 is pushed to move. With the help of the spring 7, after the pusher 8 abuts against the arc-shaped abutment plate 2, the spring 7 is compressed. After the arc-shaped abutment plate 2 abuts against the plastic hose, the connecting disc 9 is rotated to make the connecting disc 9 threadedly connected to the printing rod body 1, thereby fixing the cross pusher 10.

[0036] Reference Figure 2 The end of the cross pusher 10 away from the connecting plate 9 is tapered. The tapered cross pusher 10 can be easily inserted between the four first moving plates 5 to push the first moving plates 5.

[0037] Reference Figure 2 and Figure 3 Springs 7 are respectively sleeved on fixed rods 4. The fixed rods 4 can improve the stability of springs 7 and prevent springs 7 from bending when contracting, thus affecting the service life of springs 7.

[0038] Reference Figure 1 The printing rod body 1 has connecting plates 11 at both ends. Connecting rods 12 are fixedly connected to both ends of one side wall of the connecting plate 11. The end of the connecting rod 12 away from the connecting plate 11 is fixedly connected to the printing rod body 1. The side wall of the connecting plate 11 away from the connecting rod 12 is fixedly connected to a connector 13 for connecting to the printing equipment. The connector 13 is connected to the printing equipment, and the connecting plate 11 and the connecting rod 12 facilitate the rotation of the printing rod body 1.

[0039] Reference Figure 3 and Figure 4 The end of the positioning rod 3 away from the arc-shaped abutment plate 2 is fixedly connected to the first limiting plate 14, and the end of the fixing rod 4 away from the printing rod body 1 is fixedly connected to the second limiting plate 15. The first limiting plate 14 can prevent the positioning rod 3 from sliding out of the printing rod body 1, causing the arc-shaped abutment plate 2 to fall off. The second limiting plate 15 can prevent the first moving plate 5 and the second moving plate 6 from falling off the fixing rod 4.

[0040] Reference Figure 3 An annular limiting baffle 16 is fixedly connected to both ends of the printing rod body 1 on one side of the fixing rod 4. The annular limiting baffle 16 abuts against the connecting plate 9. When the connecting plate 9 is threaded to the printing rod body 1, the connecting plate 9 abuts against the annular limiting baffle 16, which can limit the distance of the connecting plate 9 into the printing rod body 1 and prevent the connecting plate 9 from contacting the fixing rod 4.

[0041] Reference Figure 1 and Figure 4The end of the connecting plate 9 away from the printing rod body 1 is fixedly connected to a rotating plate 17. The rotating plate 17 facilitates the rotation of the connecting plate 9, allowing for the assembly and disassembly of the connecting plate 9.

[0042] The implementation principle of the printing rod for printing equipment in this application embodiment is as follows: In use, a plastic hose is sleeved on four arc-shaped abutment plates 2. Then, a cross pusher block 10 is inserted into the printing rod body 1, pushing the first moving plate 5 to move. The first moving plate 5 pushes the second moving plate 6 through the spring 7, causing the push rod 8 to move. The push rod 8 pushes the arc-shaped abutment plates 2 away from the printing rod body 1, so that the arc-shaped abutment plates 2 abut against the plastic hose. At the same time, through the spring 7, after the push rod 8 abuts against the arc-shaped abutment plates 2, the cross pusher block 10 pushes the first moving plate 5, causing the spring 7 to contract and prevent further pushing of the second moving plate 6. Then, by rotating the connecting plate 9, the connecting plate 9 is threadedly connected to the printing rod body 1, fixing the cross pusher block 10 and fixing the plastic hose. This avoids heating and cooling the plastic hose as much as possible, which can easily cause material aging and reduce the durability of the plastic hose.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
