Description

Technical Field

[0001] The utility model relates to the technical field of trunnion connection, in particular to a novel transmission connection device. Background Art

[0002] The end sealing cylinder of the packaging machine is a pneumatic component used in packaging machines, mainly used to control the end sealing process of packaging materials. The end sealing cylinder uses pneumatic pressure to fold, compact and seal the packaging film to ensure the integrity and sealing of the packaging.

[0003] The shaft heads on both sides of the middle ear shaft in the transmission connection between the end seal cylinder and the bracket of the packaging machine are often worn. This is mainly because the end seal cylinder has a small movement. The manufacturer directly inserts the ear shaft head and the ear shaft base for friction linkage. Over time, the ear shaft head or the ear shaft base connection hole will be severely worn to form an end seal gap, which will cause a gap in the end seal and cause product leakage. The wear degree is high and the failure rate is high, resulting in frequent product abnormalities. Therefore, a new transmission connection device is proposed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a new type of transmission connection device, which has the advantages of changing the connection mode from rotational friction to rolling friction and reducing wear, and solves the problem that the connection hole of the ear shaft head or the ear shaft base is seriously worn to form an end seal gap, thereby causing the end seal to have a gap and cause product leakage, high wear, high failure rate, and frequent product abnormalities.

[0005] To achieve the above object, the utility model provides the following technical solutions: a novel transmission connection device, comprising a connection seat and a base, wherein the connection seat is movably mounted on the top of the inner side of the base, and further comprises a bearing and a reserved hole;

[0006] The bearing is movably installed on the inner side of the connecting seat;

[0007] The reserved holes are provided at the upper and lower ends of the outer wall of the connecting seat;

[0010] Wherein, the positioning bolt passes through the nut column and extends into the inner side of the connecting seat and is located at the front and rear ends of the bearing.

[0011] When using a new transmission connection device in the technical solution, install the bearing to the reserved position on the inner side of the connection seat. Ensure that the bearing is correctly placed and can rotate freely. Pass the nut column through the reserved holes at the upper and lower ends of the outer wall of the connection seat, and ensure that one end of the nut column is flush with the inner wall of the connection seat. Pass the positioning bolt through the nut column and extend it into the inner side of the connection seat so that it is located at the front and rear ends of the bearing. Note that the positioning bolt should be in contact with the bearing but not fixedly connected to allow the bearing to rotate between the positioning bolts. Weld and install the connection column on both sides of the connection seat, and open a screw hole on the connection column. Pass the connecting shaft through the inner side of the bearing to ensure that the connecting shaft can rotate freely in the bearing. Fix the cylinder at the end of the connecting shaft away from the bearing. Ensure that the cylinder is firmly installed and the connecting part of the connecting shaft and the cylinder can withstand the expected load. Flexibly insert the mounting bolts in the mounting holes on both sides of the bottom of the base, and fix the base to the connecting column with screws. Ensure that the base is stably installed and firmly connected to the connection seat. After completing all installation steps, check the assembly of the entire transmission connection device to ensure that all components are correctly installed and can work properly. Make necessary adjustments to ensure the stability and functionality of the device. After installation, perform functional tests to check whether the cylinder moves as expected and whether the bearings can reduce friction and improve transmission efficiency.

[0012] Preferably, connecting columns are respectively welded and installed on both sides of the connecting seat, and screw holes are provided on the two connecting columns.

[0013] By welding the connection column, a stable connection point can be provided, increasing the rigidity and stability of the connection base. The design of the screw hole allows the use of screws to fix other components, providing a flexible installation method.

[0014] Preferably, mounting holes are respectively opened on both sides of the bottom of the base, mounting bolts are movably inserted into the mounting holes, and the base is fixedly connected to the connecting column by screws.

[0015] The mounting holes and the movable mounting bolts provide the ability to quickly install and remove, which is convenient for maintenance and adjustment. The fixed connection between the base and the connecting column ensures the structural stability of the entire device.

[0016] Preferably, a connecting shaft passes through the inner side of the bearing, and a cylinder is fixedly mounted on one end of the connecting shaft away from the bearing.

[0017] This design allows the cylinder to be directly connected to the bearing, reducing energy loss during transmission and improving transmission efficiency. At the same time, the fixed installation of the cylinder can ensure the stability and accuracy of the cylinder during operation.

[0018] Preferably, the number of the reserved holes is four, and the bearing is movably mounted on the inner side of the connecting seat on the opposite side of the four reserved holes.

[0020] Preferably, one end of the nut column passes through the reserved hole, and the other end of the nut column is flush with the inner wall of the connecting seat.

[0021] The design of the nut column allows it to rotate freely in the reserved hole, which is convenient for installing and adjusting the positioning bolts. The design that is flush with the inner wall of the connecting seat helps to maintain a neat appearance and reduce installation errors.

[0022] Preferably, one end of the positioning bolt passes through the nut column and contacts the front and rear ends of the bearing but is not fixedly connected.

[0023] The design of the positioning bolt allows the bearing to be axially adjusted within a certain range without causing fixed constraints on the bearing. This design improves the installation flexibility of the bearing and helps to adapt to different installation requirements and adjustments.

[0024] Compared with the prior art, the beneficial effects of the utility model are as follows:

The bearing usually contains a series of rolling elements inside, which roll between the inner and outer rings instead of sliding. This design significantly reduces the friction between the contact surfaces, and provides installation points for the positioning bolts by providing reserved holes at the upper and lower ends of the outer wall of the connection seat and embedding the nut column therein. This design helps to accurately fix the position of the bearing and ensure that it rolls on the correct track, and the positioning bolt passes through the nut column and extends into the inner side of the connection seat and is located at the front and rear ends of the bearing. This design allows the bearing to be positioned and installed by the positioning bolt, and since the bearing realizes rolling friction, the wear rate of rolling friction is much lower than that of traditional sliding friction. This means that the service life of the bearing and related components is longer and the maintenance cost is lower. The reduction of rolling friction not only reduces energy loss, but also improves transmission efficiency. This is particularly important for application scenarios that require fast response and precise control. Reducing friction and wear can reduce the heat generated by friction and reduce thermal deformation of components, thereby improving the reliability of the entire transmission connection device, achieving the effect of changing the connection mode from rotational friction to rolling friction and reducing wear.

The positioning bolt 3 passes through the nut column 7 and extends into the inner side of the connection seat 2 and is located at the front and rear ends of the bearing 6. The bearing 6 is a key component for achieving rolling friction. The bearing 6 usually contains a series of rolling elements inside, which roll between the inner and outer rings instead of sliding. This design significantly reduces the friction between the contact surfaces. By opening the reserved holes 8 at the upper and lower ends of the outer wall of the connection seat 2 and embedding the nut column 7 therein, a mounting point is provided for the positioning bolt 3. This design helps to accurately fix the position of the bearing 6 and ensure that it rolls on the correct track. The positioning bolt 3 passes through the nut column 7 and extends into the inner side of the connection seat 2 and is located at the front and rear ends of the bearing 6. This design allows the bearing 6 to be positioned and installed through the positioning bolt 3. Since the bearing 6 achieves rolling friction, the wear rate of rolling friction is much lower than that of traditional sliding friction. This means that the service life of bearing 6 and related components is longer and the maintenance cost is lower. The reduction of rolling friction not only reduces energy loss, but also improves transmission efficiency. This is particularly important for application scenarios that require fast response and precise control. Reducing friction and wear can reduce the heat generated by friction and reduce the thermal deformation of components, thereby improving the reliability of the entire transmission connection device, achieving the effect of changing the connection mode from rotational friction to rolling friction and reducing wear.

At the same time, the fixed installation of the cylinder can ensure the stability and accuracy of the cylinder during operation.

[0041] Furthermore, the number of the reserved holes 8 is four, and the bearing 6 is movably mounted on the inner side of the connecting seat 2 on the opposite side of the four reserved holes 8 .

[0042] The four reserved holes 8 provide better support and fixation, making the positioning of the bearing 6 in the connecting seat 2 more stable, helping to reduce the displacement and vibration of the bearing 6 and improving the running stability of the entire device.

[0043] Furthermore, one end of the nut column 7 passes through the reserved hole 8 , and the other end of the nut column 7 is flush with the inner wall of the connecting seat 2 .
