[0025] Embodiment 1

[0026] As Figures 1-4As shown, a carton pre-pressing mechanism that is easy to adjust. The carton pre-pressing mechanism includes a pre-pressing machine frame 1, an internal roller 4, a fixing frame 5, a mounting part 6, and a pre-pressing roller 3: The internal roller 4 is arranged above the pre-pressing machine frame 1. The cross-section of the internal roller 4 is circularly designed, which is convenient for the components on its surface to rotate. This carton pre-pressing mechanism that is easy to adjust also includes a fixed side plate 2. The fixed side plate 2 is a defined plate body that provides support for the internal roller 4, the mounting part 6, the fixing frame 5, and the pre-pressing roller 3. The fixed side plate 2 is arranged above the pre-pressing machine frame 1. The fixed side plate 2 arranged above the pre-pressing machine frame 1 ensures that while the internal roller 4, the mounting part 6, the fixing frame 5, and the pre-pressing roller 3 are adjusted on the pre-pressing machine frame 1, it will not affect the pre-pressing treatment of the carton. The fixing frame 5 is sleeved outside the internal roller 4 and will be in direct contact with the carton during use. At the same time, when the carton moves, the pre-pressing roller 3 will move along and rotate on the surface of the internal roller 4 to ensure uniform distribution of the pre-pressure on the carton; The internal roller 4 includes a circular ring 52 inserted outside the fixing frame 5. The side of the fixed side plate 2 is fixed to the end of the connecting frame 51 away from the circular ring 52; The circular ring 52 is a circular metal ring that is loosely sleeved outside the internal roller 4 and the pre-pressing roller 3. While providing conditions for the limitation of the pre-pressing roller 3, it will not affect the rotation of the pre-pressing roller 3. A second insertion slot 54 is opened between the circular ring 52 and the internal roller 4. The second insertion slot 54 is circularly designed. The diameter of the second insertion slot 54 is larger than the diameter of the cylinder 31. The second insertion slot 54 provides space for the rotation of the pre-pressing roller 3; The mounting part 6 is arranged inside the fixing frame 5; The mounting part 6 includes a limiting plate 61 inserted inside the circular ring 52. There are two mounting parts 6, which are symmetrically distributed on the transverse axis of the pre-pressing roller 3. The pre-pressing roller 3 includes a cylinder 31 inserted outside the internal roller 4 and an annular groove 32 opened on the surface of the cylinder 31. The annular groove 32 and the cylinder 31 are integrally formed by welding. The bottom of the limiting plate 61 is inserted inside the annular groove 32 to insert and limit the pre-pressing roller 3 to prevent the pre-pressing roller 3 from falling off the internal roller 4 during rotation; The pre-pressing roller 3 is sleeved outside the internal roller 4.

[0027] The effect achieved by the entire Example 1 is that during use, first sleeve the cylinder 31 and the internal roller 4. When the annular groove 32 reaches below the limiting plate 61, the limiting plate 61 will insert and limit the annular groove 32 to limit the sleeving between the internal roller 4 and the pre-pressing roller 3. When the carton reaches below the pre-pressing roller 3 for pre-pressing, the cylinder 31 will be in direct contact with the carton. At the same time, when the carton moves, the pre-pressing roller 3 will move along and rotate on the surface of the internal roller 4 to ensure uniform distribution of the pre-pressure on the carton. At this time, the second insertion slot 54 provides a rotation space for the cylinder 31.

[0028] Example 2

[0029] As Figures 1-4As shown, a carton pre-pressing mechanism that is easy to adjust. The fixing frame 5 further includes a connecting frame 51 fixed on the surface of the circular ring 52, which is used to fix the position of the circular ring 52 to ensure that the circular ring 52 can be sleeved outside the built-in roller 4. An internal groove 53 is opened on the circular ring 52 on the opposite side of the connecting frame 51. The diameter of the internal groove 53 is larger than the diameter of the second insertion slot 54, providing a moving space for the installation part 6.

[0030] A circular groove is provided inside the internal groove 53. The installation part 6 further includes a limiting spring 63 partially inserted into the circular groove. During use, the limiting spring 63 will move up and down inside the internal groove 53. When the limiting spring 63 is in its natural state, it will exert a force on the limiting plate 61, causing the limiting plate 61 to be inserted into the undulating groove 62. As Figure 2 shown, at this time, the position of the pre-pressing roller 3 is limited. The undulating groove 62 starts from the side of the limiting plate 61 away from the fixing frame 5. The undulating groove 62 and the limiting plate 61 are integrally formed. A rubber block 64 is fixed to the bottom of the limiting plate 61. The rubber block 64 is made of soft rubber. When it is inserted into the annular groove 32, it will reduce the wear of the annular groove 32 during use. The bottom of the limiting spring 63 is fixedly connected to the inside of the circular groove. The insertion of the circular groove and the limiting spring 63 will limit the limiting spring 63 to only move up and down, reducing the probability of the limiting spring 63 shaking left and right. The bottom of the limiting spring 63 is fixedly connected to the top of the limiting plate 61, and the bottom of the limiting spring 63 abuts against the inside of the annular groove 32.

[0031] The pre-pressing machine frame 1 includes a first insertion slot 13 opened at the top of the pre-pressing machine frame 1. The first insertion slot 13 and the pre-pressing machine frame 1 are integrally designed. A driving part 14 is locked inside the first insertion slot 13 by bolts. The first insertion slot 13 is externally powered during use to drive the fixed side plate 2 to move up and down. The driving end of the driving part 14 and the side of the fixed side plate 2 are locked by bolts. During use, the entire mechanism is externally powered, and the driving part 14 is controlled through the control panel to drive the fixed side plate 2 to move vertically above the pre-pressing machine frame 1 to pre-press the carton passing under the pre-pressing roller 3. At the same time, when the length requirement of the pre-pressing roller 3 changes, the driving part 14 can be driven to lift the fixed side plate 2, push the undulating groove 62, so that the rubber block 64, the limiting spring 63 and the annular groove 32 are separated, the pre-pressing roller 3 is disassembled and replaced, and then the driving part 14 is controlled to drive the fixed side plate 2 to a suitable position. In this way, it is not necessary to stop the machine to replace the pre-pressing roller 3, reducing the shutdown loss of the machine.

[0032] The pre-press machine frame 1 further includes a transport roller 11 disposed inside the pre-press machine frame 1. The transport rollers 11 are connected by a pulley assembly at a position inside the pre-press machine frame 1. The transport roller 11 is driven to rotate by a driving motor inside the pre-press machine frame 1 to transport the carton. Limiting rollers 12 are fixed on both sides of the pre-press machine frame 1. The limiting rollers 12 are used to limit the belt of the connecting part. A transport groove 15 is locked to the top of the pre-press machine frame 1 by bolts, which is used to output the pre-pressed carton.

[0033] The effect achieved by the entire second embodiment is that when in use, the annular groove 32 is inserted and limited through the limiting plate 61 and the limiting spring 63. Then, by controlling the driving part 14 inside the first insertion groove 13, at this time, the driving part 14 will adjust the height of the fixed side plate 2 until the pre-pressing roller 3 on one side of the fixed side plate 2 reaches the specified position. At this time, control the driving motor to drive the transport roller 11 to rotate to transport the carton. When the carton reaches the position of the pre-pressing roller 3 on one side of the fixed side plate 2, the pre-pressing roller 3 will perform pre-pressing treatment on the carton.

[0034] Working principle: When using this easily adjustable carton pre-pressing mechanism, an external power supply is connected. First, the cylinder 31 and the built-in roller 4 are sleeved, and the annular groove 32 is inserted and limited through the limiting plate 61 and the limiting spring 63 to limit the position of the cylinder 31. When the annular groove 32 reaches below the limiting plate 61, the limiting plate 61 will insert and limit the annular groove 32 to limit the socket connection between the built-in roller 4 and the pre-pressing roller 3. Then, by controlling the driving part 14 inside the first insertion groove 13, at this time, the driving part 14 will adjust the height of the fixed side plate 2 until the pre-pressing roller 3 on one side of the fixed side plate 2 reaches the specified position. At this time, control the driving motor to drive the transport roller 11 to rotate to transport the carton. The cylinder 31 will be in direct contact with the carton. At the same time, when the carton moves, the pre-pressing roller 3 will follow and rotate on the surface of the built-in roller 4 to ensure uniform distribution of the pre-pressure on the carton. At this time, the second insertion groove 54 provides a rotation space for the rotation of the cylinder 31, and finally the work is completed.

[0035] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
