Description

Technical Field

[0001] The present application relates to the technical field of cardboard processing, and in particular, to an auxiliary device for a cardboard indentation machine. Background Art

[0002] In the cardboard packaging industry, cardboard indentation machines are widely used for creasing cardboard so that the cardboard can be folded according to preset creases.

[0003] The existing Chinese patent document with the publication number CN219583611U discloses a corrugated cardboard slitting and indentation machine, which includes a conveying device. The conveying device includes a fixed frame and a conveyor belt. The conveyor belt is conveyed on the fixed frame to convey the cardboard, and a driving device is installed on the conveying device. The driving device is connected to a transmission device, and a plurality of slitting knives and indentation knives are installed on the transmission device. The conveyor belt drives the cardboard to move, so that the cardboard passes through the indentation knife and the slitting knife in sequence for indentation and slitting.

[0004] In view of the above related technologies, when the cardboard is conveyed on the conveyor belt, it is easily affected by vibration and moves relative to the conveyor belt, resulting in the deviation of the cardboard position, which causes the deviation of the cardboard indentation position and affects the processing quality of the cardboard. Utility Model Content

[0005] In order to improve the processing quality of cardboard, the present application provides an auxiliary device for a cardboard indentation machine.

[0006] The present application provides an auxiliary device for a cardboard indentation machine, adopting the following technical solutions:

[0007] An auxiliary device for a cardboard indentation machine, which cooperates with the cardboard indentation machine. The cardboard indentation machine includes a frame and a conveyor belt. The conveyor belt is conveyed on the frame. The auxiliary device includes: a limiting component, provided with at least two groups, and multiple groups of the limiting components are distributed along the direction perpendicular to the conveying direction of the conveyor belt; each group of the limiting components includes a connecting frame and an abutting rod; the connecting frame is installed on the frame, the abutting rod is connected to the connecting frame, and the abutting rod abuts against the upper surface of the conveyor belt. The length extension direction of the abutting rod is parallel to the conveying direction of the conveyor belt; a space for placing the cardboard is formed between the abutting rods of two adjacent groups of the limiting components.

[0008] By adopting the above technical solutions, when the cardboard is placed on the conveyor belt, it will be restricted in the space between two adjacent abutting rods. These abutting rods effectively reduce the deviation of the cardboard during conveying due to vibration or other reasons, so that the cardboard can be folded according to the preset position during the indentation process. This not only significantly improves the processing quality of the cardboard, but also reduces the rejection rate caused by deviation, thereby improving the overall production efficiency.

[0009] Optionally, a guide rod is connected to the frame. The length direction of the guide rod is perpendicular to the conveying direction of the conveyor belt. The connecting frame is movable along the length direction of the guide rod on the guide rod, and a positioning member for relatively locking the connecting frame and the guide rod is provided on the connecting frame.

[0010] By adopting the above technical solution, by adjusting the connecting frame along the length direction of the guide rod, the distance and position between the abutting rods of two adjacent limiting components can be adjusted, so as to improve the adaptability of the auxiliary device.

[0011] Optionally, the connecting frame is slidably sleeved on the guide rod, and the positioning member is threadedly connected to the connecting frame and can abut against the guide rod.

[0012] Optionally, a groove is formed in the guide rod along its own length direction, and an elastic displacement-resistant member is embedded in the groove of the guide rod. The positioning member can enter the groove and abut against the elastic displacement-resistant member to deform the elastic displacement-resistant member.

[0013] By adopting the above technical solution, through the abutment between the positioning member and the elastic displacement-resistant member, the friction force between the positioning member and the guide rod is enhanced.

[0014] Optionally, an adjusting seat is provided on the frame. The guide rod moves up and down on the adjusting seat, and a locking member for positioning the guide rod on the adjusting seat is provided on the guide rod.

[0015] By adopting the above technical solution, by adjusting the height of the guide rod on the adjusting seat, the distance and tightness between the abutting rod and the conveyor belt can be adjusted.

[0016] Optionally, the connecting frames at the same end of the abutting rods in all the limiting components are connected to the same guide rod.

[0017] By adopting the above technical solution, the connecting frames installed on the same guide rod can act together when the height of the guide rod is adjusted, so as to improve the convenience of adjusting the height of different groups of limiting components.

[0018] Optionally, the adjusting seat is detachably connected to the frame.

[0019] Optionally, there are two sets of connecting frames in each set of limiting components. The two sets of connecting frames are distributed at both ends of the frame along the conveying direction of the conveyor belt. The abutting rod simultaneously slides through the two sets of connecting frames along the conveying direction of the conveyor belt, and a limiting member for positioning the abutting rod is provided on the connecting frame.

[0020] By adopting the above technical solution, by using a double connecting frame, the stability of the abutting rod is further enhanced in this auxiliary device.

[0021] Optionally, the middle part of the surface of the abutting rod facing the conveyor belt is recessed upward.

[0022] By adopting the above technical solution, the recess of the abutting rod can reduce the contact area between the abutting rod and the conveyor belt, thereby reducing the friction between the abutting rod and the conveyor belt, and reducing the wear caused to the conveyor belt by the abutting rod during the conveyor belt transmission process.

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

[0024] 1. Multiple groups of limiting components are distributed along the direction perpendicular to the conveyor belt transmission direction to form a space for placing cardboard, so as to guide the position of the cardboard during the transmission process and improve the accuracy of the cardboard indentation position.

[0025] 2. Through the adjustable connecting frame and guiding rod, the position and height of the limiting components are adjustable, adapting to the processing requirements of cardboard of different sizes, and improving the flexibility and application range of the equipment.

[0026] 3. By arranging elastic displacement-resistant components on the guiding rod, the friction between the positioning component and the guiding rod is increased, and the stability of the locking effect is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The following will Figures 1 - 3 describe this application in further detail with reference to the appended

[0032] An embodiment of this application discloses an auxiliary device for a cardboard indentation machine. Refer to Figure 1, The auxiliary device of the cardboard indentation machine is cooperated with the cardboard indentation machine. The cardboard indentation machine includes a frame 1, a conveyor belt 2, an indentation knife 3 and a slitting knife 4. The conveyor belt 2 is conveyed on the frame 1 for conveying the cardboard. The indentation knife 3 and the slitting knife 4 move up and down on the frame 1, and the distances between the indentation knives 3 and between the slitting knives 4 can both be adjusted. The above is the prior art and will not be elaborated here.

[0033] Refer to Figure 1 and Figure 2 , The auxiliary device of the cardboard indentation machine includes a limiting component 5. There are at least two groups of the limiting components 5, and multiple groups of the limiting components 5 are distributed along the direction perpendicular to the conveying direction of the conveyor belt 2. The number of groups of the limiting components 5 is one more than the number of the conveyed cardboard placed along the conveying direction of the conveyor belt 2 in the vertical direction. A space for limiting and guiding a group of cardboard is formed between two adjacent groups of the limiting components 5.

[0034] Specifically, each group of the limiting components 5 includes a connecting frame 51 and an abutting rod 52. The number of the abutting rods 52 is one, and the number of the connecting frames 51 is two. The two connecting frames 51 are respectively installed at the two ends of the abutting rod 52 far away from each other. Among them, the two connecting frames 51 are respectively installed at the two ends of the frame 1 along the conveying direction of the conveyor belt 2, and the abutting rod 52 abuts against the upper surface of the conveyor belt 2. Particularly, the length extension direction of the abutting rod 52 is set to be parallel to the conveying direction of the conveyor belt 2. Through the space formed between the abutting rods 52 of two adjacent groups of the limiting components 5, the cardboard can be placed, so as to limit the cardboard during the conveying process and make the cardboard not easy to shift during the conveying process on the conveyor belt 2.

[0035] Refer to Figure 1 and Figure 2 , In order to install the connecting frame 51, two adjusting seats 10 are detachably connected to each end of the frame 1 through bolts, and a guiding rod 6 for connecting with the connecting frame 51 is installed on the two adjusting seats 10. The connecting frames 51 at the same end in multiple groups of the limiting components 5 are installed on the same guiding rod 6.

[0036] Specifically, the two adjusting seats 10 at each end of the frame 1 are respectively located on the opposite sides of the frame 1, and the space between the conveyor belt 2 and the two adjusting seats 10 is opposite. Each adjusting seat 10 is in a rod shape extending vertically, and an adjusting groove 13 extending vertically is opened on each adjusting seat 10, and the adjusting groove 13 penetrates through the opposite sides of the adjusting seat 10 along the direction perpendicular to the conveying direction of the conveyor belt 2.

[0037] The guiding rods 6 at each end of the frame 1 pass through two adjusting seats 10 at each end of the frame 1 simultaneously through the adjusting slots 13, and the guiding rods 6 extend along the direction perpendicular to the conveying direction of the conveyor belt 2. The guiding rods 6 can move up and down in the adjusting slots 13 to adjust the height of the guiding rods 6, thereby adjusting the height of the connecting frame 51 mounted on the guiding rods 6, and further adjusting the height of the abutting rod 52 to make the abutting rod 52 adapt to the height of the conveyor belt 2.

[0038] In order to position the guiding rod 6 after height adjustment, there is a locking member 11 on the guiding rod 6. Specifically, the guiding rod 6 is in the shape of a round rod, and both ends of the guiding rod 6 away from each other have external threads. The locking member 11 is in the shape of a nut and is threadedly sleeved on the guiding rod 6. The two ends of the guiding rod 6 respectively correspond to two adjusting seats 10, and each adjusting seat 10 corresponds to two locking members 11, that is, both ends of the guiding rod 6 have two locking members 11, and the two locking members 11 are respectively on the opposite sides relative to the adjusting seat 10.

[0039] When the guiding rod 6 is adjusted, the locking member 11 is away from the adjusting seat 10; when the guiding rod 6 needs to be locked, the two locking members 11 at the end of the guiding rod 6 are respectively threadedly connected to abut against the opposite sides of the adjusting seat 10, so as to position the guiding rod 6 through the frictional force between the locking member 11 and the adjusting seat 10.

[0040] Refer to Figure 1 and Figure 2 To further increase the flexibility and adaptability of the limiting component 5, the connecting frame 51 can move along the length direction of the guiding rod 6 so as to be able to adjust the position of the abutting rod 52 according to actual needs. At the same time, the connecting frame 51 is also equipped with a positioning member 7 for relatively locking the connecting frame 51 and the guiding rod 6 after adjusting the position.

[0041] Refer to Figure 2 and Figure 3 Specifically, each connecting frame 51 is in the shape of a rod extending vertically. The bottom of the connecting frame 51 is slidably sleeved on the outer wall of the guiding rod 6 along the length direction of the guiding rod 6. The two connecting frames 51 in each group of limiting components 5 are respectively sleeved on the guiding rods 6 at both ends of the frame 1 to limit the connecting frame 51 from rotating around the axis of the guiding rod 6.

[0042] The positioning member 7 is a bolt threadedly connected to the connecting frame 51. When positioning the connecting frame 51, the rod part of the positioning member 7 abuts against the guiding rod 6 to position the connecting frame 51 through the frictional force between the bolt and the guiding rod 6.

[0043] Refer to Figure 2 and Figure 3, Further, in order to improve the stability of the connecting frame 51 and the guide rod 6. A groove 8 is further formed in the guide rod 6 along its own length direction. An elastic displacement-resistant member 9 is embedded in the groove 8. The elastic displacement-resistant member 9 fits against the inner wall of the groove 8, and the elastic displacement-resistant member 9 is made of elastic rubber. The rod portion of the positioning member 7 can extend into the groove 8. When positioning the connecting frame 51, the positioning member 7 is tightened and abutted against the elastic displacement-resistant member 9, which will cause the elastic displacement-resistant member 9 to deform, thereby further increasing the locking force between the connecting frame 51 and the guide rod 6, making the connecting frame 51 not prone to looseness or displacement during use.

[0044] Refer to Figure 1 and Figure 2 , In addition, by sliding the connecting frame 51 on the guide rod 6, the adjusting seat 10 on one side of the frame 1 is removed from the frame 1, and the locking member 11 is removed so that the connecting frame 51 can be removed from one end of the guide rod 6 to disassemble the limiting component 5. Similarly, when it is necessary to install the limiting component 5, the adjusting seat 10 on one side of the frame 1 is first removed, and the locking member 11 is removed so that the limiting component 5 can be assembled onto the guide rod 6, and then the locking member 11 and the adjusting seat 10 are installed, so that the number of the limiting components 5 can be adjusted adaptively.

[0045] Further, in order to improve the adaptability of the limiting component 5, the abutting rod 52 and the connecting frame 51 are detachably connected. Specifically, the top of the connecting frame 51 has a block-shaped mounting portion 14. A mounting hole 15 for the abutting rod 52 to move through is formed in the mounting portion 14. The abutting rod 52 passes through the mounting portions 14 of two connecting frames 51 at the same time, and a limiting member 12 for positioning the abutting rod 52 is provided on the mounting portion 14. The limiting member 12 is a bolt threadedly connected to the top end of the mounting portion 14. The rod portion of the limiting member 12 passes through the mounting hole 15 and abuts against the upper surface of the abutting rod 52, so that the abutting rod 52 abuts against the mounting portion 14. Through the frictional force between the abutting rod 52 and the mounting portion 14 and the frictional force between the limiting member 12 and the abutting rod 52, the abutting rod 52 is positioned relative to the connecting frame 51.

[0046] When installing the limiting component 5 on equipment with different conveying lengths of the conveyor belt 2, it is adapted by adjusting the position of the connecting frame 51 on the abutting rod 52.

[0047] Refer to Figure 1 and Figure 3, Further, the middle part of the side of the abutting rod 52 facing the conveyor belt 2 is designed to be recessed upward to reduce the contact area between the abutting rod 52 and the conveyor belt 2, so as to reduce the tendency force of the conveyor belt 2 on the abutting rod 52 when the conveyor belt 2 is conveyed relative to the abutting rod 52. While improving the stability of the abutting rod 52, the wear of the conveyor belt 2 caused by the abutting rod 52 is reduced. In addition, the thickness of the abutting rod 52 in the vertical direction is less than the radii of the indentation knife 3 and the cutting knife 4, so that the indentation knife 3 and the cutting knife 4 do not interfere with the abutting rod 52 when pressing down on the cardboard for operation.

[0048] The implementation principle of the auxiliary device of the cardboard indentation machine according to the embodiment of the present application is as follows: First, through the adjustment groove 13 on the adjustment seat 10, the guide rod 6 is adjusted in the vertical direction, and then the guide rod 6 is fixed on the adjustment seat 10 by using the locking member 11 to adjust the vertical position of the abutting rod 52 so that the abutting rod 52 abuts against the upper surface of the conveyor belt 2. Then, by moving the connecting frame 51 on the guide rod 6 and locking it with the positioning member 7, the lateral position of the abutting rod 52 is adjusted so as to form a space for limiting the cardboard between the abutting rods 52 of two adjacent groups of limiting components 5.

[0049] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
