The adjusting device includes a guide rail disposed at the bottom of the can-standing conveyor belt, two adjusting sliders slidably connected to the guide rail, a lead screw movably connected to the adjusting sliders, and a handwheel disposed at one end of the lead screw. This automatic can-standing mechanism uses the adjusting device to adjust the distance between the two symmetrically distributed can-standing conveyor belts to a range within the diameter range of the can body, and uses the can-standing conveyor belts to clamp the can body, thereby erecting the horizontal can bodies one by one in an orderly manner.

[0004] The automatic can-standing mechanism provided by the aforementioned patent uses a can-standing conveyor belt to stand the paper can upright. However, in the actual paper can production process, before the paper can needs to be uprighted, its surface is already covered with packaging paper. When the can-standing conveyor belt stands the paper can upright, it relies on friction. This friction can easily damage the packaging paper on the surface of the paper can, affecting the production quality of the paper can. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic can-standing mechanism for a paper can production line, which aims to improve the problem that existing automatic can-standing mechanisms rely on the friction between the can-standing conveyor belt and the surface of the paper can to achieve the can-standing and turning, which easily damages the packaging paper already attached to the surface of the paper can and thus affects the quality of paper can production.

[0006] This utility model is implemented as follows: An automatic can-standing mechanism for a paper can production line includes a mounting frame. A can-standing assembly is located below the mounting frame. The can-standing assembly includes a can-standing turntable and a support head. The support head is detachably connected to the can-standing turntable, and the can-standing turntable is rotatably connected to the mounting frame. A stepper motor is located on the side of the mounting frame, and the output end of the stepper motor is connected to the can-standing turntable.

[0010] Preferably, the end of the support head facing the vertical tank turntable is provided with an insertion rod, the insertion rod is inserted into the slot, and the set screw abuts against the insertion rod to ensure that the support head is stably connected to the vertical tank turntable.

[0011] Preferably, the stepper motor has multiple fixing feet at one end of the mounting plate, and fixing holes are provided on the fixing feet. The stepper motor is fixed to the mounting plate by bolts passing through the fixing holes. The side of the stepper motor has wires, and the ends of the wires have connectors.

[0015] Preferably, the support base has an overall U-shaped structure, and both ends of the support base are provided with lifting grooves. The insert plate is inserted into the inner side of the lifting groove, and the side of the support base near the top is provided with clamping bolts for fixing the position of the mounting bracket. The bottom end of the support base is provided with a fixing seat, and the bottom surface of the fixing seat is provided with a base plate. Multiple bolt holes are evenly provided on both sides of the base plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model has a stepper motor and a can-standing assembly on the mounting frame.

[0021] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: Example 1 like Figure 1 , Figure 2 and Figure 3As shown, an automatic can-standing mechanism for a paper can production line includes a mounting frame 1. A can-standing assembly 2 is located below the mounting frame 1. The can-standing assembly 2 facilitates the rotation of the paper can, thus easily standing it upright. The can-standing assembly 2 includes a can-standing turntable 21 and a support head 22. The support head 22 is detachably connected to the can-standing turntable 21 and is easily inserted into the paper can. The can-standing turntable 21 rotates counterclockwise to lift the paper can. The can-standing assembly 2 continues to rotate until the bottom of the paper can contacts the upper surface of the mounting frame 1. Then, the support head 22 continues to rotate and detaches from the paper can, thus achieving the purpose of standing the horizontal paper can upright. The can-standing turntable 21 is rotatably connected to the mounting frame 1. A stepper motor 3 is located on the side of the mounting frame 1, and the output end of the stepper motor 3 is connected to the can-standing turntable 21. This structure allows the stepper motor 3 to drive the can-standing turntable 21 to rotate a certain angle and then stop, waiting for the paper can to be placed on the support head 22 before continuing to rotate so that the paper can is upright on the mounting frame 1. The mounting frame 1 has guide rods 11 horizontally at both ends. A double-acting screw 4 is located inside the guide rods 11. Stop bars 5 are symmetrically arranged on both sides of the mounting frame 1. The guide rods 11, in conjunction with the double-acting screws 4, move the stop bars 5 closer together or further apart, thereby limiting the movement of paper cans of different sizes and allowing the cans to stand upright. The bottom ends of the stop bars 5 are threaded to the double-acting screws 4. Rotation of the double-acting screws 4 moves the stop bars 5 on both layers of the mounting frame 1 closer together or further apart.

[0022] like Figure 2 As shown, the guide grooves 12 at both ends of the mounting frame 1 facilitate the installation of the bidirectional screw 4. Each guide groove 12 has a first bearing 13 at its front end; the first bearing 13 facilitates rotational connection with the bidirectional screw 4. A rotating opening 14 is provided in the middle of the mounting frame 1, allowing the support head 22 to protrude from the upper surface of the mounting frame 1, thus facilitating the horizontal movement of the paper can as it is fitted onto the support head 22. A mounting plate 15 is provided on one side of the bottom of the mounting frame 1, with a second bearing 16 in the middle of the mounting plate 15 for mounting the upright can assembly 2 and the stepper motor 3. This facilitates the rotation of the upright can assembly 2 and the fixation of the stepper motor 3, allowing the stepper motor 3 to drive the upright can assembly 2 to rotate.

[0023] like Figure 3As shown, a connecting shaft 211 is provided in the middle of the vertical tank turntable 21. The connecting shaft 211 is easily connected to the second bearing 16 by interference fit, facilitating the rotation of the vertical tank turntable 21. A drive slot 212 is provided at the end of the connecting shaft 211 facing the stepper motor 3. The drive slot 212 facilitates the connection between the output end of the stepper motor 3 and the vertical tank turntable 21, allowing the stepper motor 3 to drive the vertical tank turntable 21 to rotate. Multiple connecting rods 213 are evenly distributed on the side of the vertical tank turntable 21. A slot 215 is provided at the end of each connecting rod 213. A set screw 214 is provided on the side of the connecting rod 213 aligned with the slot 215. The connecting rod 213 and slot 215 facilitate the installation of the support head 22, allowing for easy insertion and fixation of the support head 22. The end of the support head 22 facing the vertical can turntable 21 is provided with a plug rod 221. The plug rod 221 is inserted into the slot 215, and the set screw 214 abuts against the plug rod 221, ensuring that the support head 22 is stably connected to the vertical can turntable 21. This structure also makes it easy to replace the support head 22 of different specifications according to the usage requirements, thereby ensuring that the support head 22 can stably support the paper can.

[0024] like Figure 4 As shown, the stepper motor 3 has multiple fixing feet 31 at one end that is attached to the mounting plate 15. Each fixing foot 31 has a fixing hole 32. The stepper motor 3 is fixed to the mounting plate 15 by bolts passing through the fixing holes 32, ensuring stable mounting of the stepper motor 3 on the mounting plate 15. The side of the stepper motor 3 has a wire 33, and the end of the wire 33 has a connector 34. The wire 33 and connector 34 facilitate connection of the stepper motor 3 to the control system of the paper can production line.

[0025] like Figure 5 As shown, a separator block 41 is provided in the middle of the bidirectional screw 4, which facilitates the separation of the two threads in different directions on the bidirectional screw 4. Both ends of the bidirectional screw 4 are provided with adapter parts 42, which are interference-fitted with the first bearing 13 to facilitate the rotation of the bidirectional screw 4. One end of the bidirectional screw 4 extends out of the guide rod 11 and is provided with a rotating handle 43, which facilitates the rotation of the bidirectional screw 4.

[0026] like Figure 6 As shown, the front and rear ends of the stop bar 5 are provided with connecting plates 51, the bottom end of the connecting plate 51 is provided with a connecting block 52, the middle of the connecting block 52 is provided with a threaded hole 53, the threaded hole 53 is threadedly connected to the double-acting screw 4. This structure facilitates the rotation of the bottom end of the stop bar 5 and the double-acting screw 4. The rotation of the double-acting screw 4 drives the two stop bars 5 to move closer or further apart, thereby facilitating the position adjustment of the stop bars 5 on both sides of the mounting frame 1.

[0027] Example 2 like Figure 1 , Figure 2 and Figure 3As shown, an automatic can-standing mechanism for a paper can production line includes a mounting frame 1. A can-standing assembly 2 is located below the mounting frame 1. The can-standing assembly 2 facilitates the rotation of the paper can, thus easily standing it upright. The can-standing assembly 2 includes a can-standing turntable 21 and a support head 22. The support head 22 is detachably connected to the can-standing turntable 21 and is easily inserted into the paper can. The can-standing turntable 21 rotates counterclockwise to lift the paper can. The can-standing assembly 2 continues to rotate until the bottom of the paper can contacts the upper surface of the mounting frame 1. Then, the support head 22 continues to rotate and detaches from the paper can, thus achieving the purpose of standing the horizontal paper can upright. The can-standing turntable 21 is rotatably connected to the mounting frame 1. A stepper motor 3 is located on the side of the mounting frame 1, and the output end of the stepper motor 3 is connected to the can-standing turntable 21. This structure allows the stepper motor 3 to drive the can-standing turntable 21 to rotate a certain angle and then stop, waiting for the paper can to be placed on the support head 22 before continuing to rotate so that the paper can is upright on the mounting frame 1. The mounting frame 1 has guide rods 11 horizontally at both ends. A double-acting screw 4 is located inside the guide rods 11. Stop bars 5 are symmetrically arranged on both sides of the mounting frame 1. The guide rods 11, in conjunction with the double-acting screws 4, move the stop bars 5 closer together or further apart, thereby limiting the movement of paper cans of different sizes and allowing the cans to stand upright. The bottom ends of the stop bars 5 are threaded to the double-acting screws 4. Rotation of the double-acting screws 4 moves the stop bars 5 on both layers of the mounting frame 1 closer together or further apart.

[0028] like Figure 2 As shown, the guide grooves 12 at both ends of the mounting frame 1 facilitate the installation of the bidirectional screw 4. Each guide groove 12 has a first bearing 13 at its front end; the first bearing 13 facilitates rotational connection with the bidirectional screw 4. A rotating opening 14 is provided in the middle of the mounting frame 1, allowing the support head 22 to protrude from the upper surface of the mounting frame 1, thus facilitating the horizontal movement of the paper can as it is fitted onto the support head 22. A mounting plate 15 is provided on one side of the bottom of the mounting frame 1, with a second bearing 16 in the middle of the mounting plate 15 for mounting the upright can assembly 2 and the stepper motor 3. This facilitates the rotation of the upright can assembly 2 and the fixation of the stepper motor 3, allowing the stepper motor 3 to drive the upright can assembly 2 to rotate.

[0029] like Figure 3As shown, a connecting shaft 211 is provided in the middle of the vertical tank turntable 21. The connecting shaft 211 is easily connected to the second bearing 16 by interference fit, facilitating the rotation of the vertical tank turntable 21. A drive slot 212 is provided at the end of the connecting shaft 211 facing the stepper motor 3. The drive slot 212 facilitates the connection between the output end of the stepper motor 3 and the vertical tank turntable 21, allowing the stepper motor 3 to drive the vertical tank turntable 21 to rotate. Multiple connecting rods 213 are evenly distributed on the side of the vertical tank turntable 21. A slot 215 is provided at the end of each connecting rod 213. A set screw 214 is provided on the side of the connecting rod 213 aligned with the slot 215. The connecting rod 213 and slot 215 facilitate the installation of the support head 22, allowing for easy insertion and fixation of the support head 22. The end of the support head 22 facing the vertical can turntable 21 is provided with a plug rod 221. The plug rod 221 is inserted into the slot 215, and the set screw 214 abuts against the plug rod 221, ensuring that the support head 22 is stably connected to the vertical can turntable 21. This structure also makes it easy to replace the support head 22 of different specifications according to the usage requirements, thereby ensuring that the support head 22 can stably support the paper can.

[0030] like Figure 4 As shown, the stepper motor 3 has multiple fixing feet 31 at one end that is attached to the mounting plate 15. Each fixing foot 31 has a fixing hole 32. The stepper motor 3 is fixed to the mounting plate 15 by bolts passing through the fixing holes 32, ensuring stable mounting of the stepper motor 3 on the mounting plate 15. The side of the stepper motor 3 has a wire 33, and the end of the wire 33 has a connector 34. The wire 33 and connector 34 facilitate connection of the stepper motor 3 to the control system of the paper can production line.

[0031] like Figure 5 As shown, a separator block 41 is provided in the middle of the bidirectional screw 4, which facilitates the separation of the two threads in different directions on the bidirectional screw 4. Both ends of the bidirectional screw 4 are provided with adapter parts 42, which are interference-fitted with the first bearing 13 to facilitate the rotation of the bidirectional screw 4. One end of the bidirectional screw 4 extends out of the guide rod 11 and is provided with a rotating handle 43, which facilitates the rotation of the bidirectional screw 4.

[0032] like Figure 6 As shown, the front and rear ends of the stop bar 5 are provided with connecting plates 51, the bottom end of the connecting plate 51 is provided with a connecting block 52, the middle of the connecting block 52 is provided with a threaded hole 53, the threaded hole 53 is threadedly connected to the double-acting screw 4. This structure facilitates the rotation of the bottom end of the stop bar 5 and the double-acting screw 4. The rotation of the double-acting screw 4 drives the two stop bars 5 to move closer or further apart, thereby facilitating the position adjustment of the stop bars 5 on both sides of the mounting frame 1.

[0033] like Figure 1 and Figure 2As shown, it also includes a support base 6, and the bottom surfaces of the mounting frame 1 are provided with insert plates 17 at both ends. The insert plates 17 are set vertically downward and are connected to the support base by insertion, so that the support base 6 can be connected to the mounting frame 1, thereby facilitating the height adjustment of the mounting frame 1 and making the entire vertical tank mechanism more flexible to use.

[0034] like Figure 7 As shown, the support base has an overall U-shaped structure, and both ends of the support base are provided with lifting grooves 61. The insert plate 17 is inserted into the inner side of the lifting groove 61, which facilitates the installation and adjustment of the mounting frame 1 and makes the mounting frame 1 easy to use. In addition, the support base has a clamping bolt 62 near the top on its side to fix the position of the mounting frame 1 and ensure the stability of the entire vertical tank mechanism. The bottom end of the support base is provided with a fixing seat 63, and the bottom surface of the fixing seat 63 is provided with a base plate 64. Multiple bolt holes 65 are evenly provided on both sides of the base plate 64. This structure facilitates fixing the position of the support base with bolts and ensures the stable use of the support base.

[0035] Working principle: During use, the entire upright can device is positioned between the horizontal and vertical paper can conveying mechanisms, with the support head 22 facing the horizontal paper can conveying mechanism. First, the entire mechanism is fixed by bolts between the fixed seat 63 of the support base 6 and the base plate 64. Then, according to the size of the paper can to be uprighted, the rotating handle 43 at the end of the bidirectional screw 4 is rotated, causing the bidirectional screw 4 to rotate under the support of the first bearing 13 and guide rod 11 of the guide grooves 12 at both ends of the mounting frame 1. The reverse threads on both sides of the external partition block 41 will drive the connecting blocks 52 of the end stops 5 to move. With the guidance of the guide rod 11, the two end stops 5 move closer or further apart to limit the paper can. At the same time, the height of the mounting frame 1 can be adjusted by the lifting groove 61 of the support base and the insert plate 17. After adjustment, the position of the mounting frame 1 is fixed by the clamping bolts 62 on the side of the support base. After the upright can operation begins, the stepper motor 3, which is connected to the production line control system through the wire 33 and the connector 34, will drive the upright can turntable 21 to rotate. As the vertical can turntable 21 rotates, the support head 22 protrudes from the rotation port 14 in the middle of the mounting frame 1. Then, the stepper motor 3 stops operating, and the horizontal can conveying mechanism causes one end of the horizontal can to be fitted onto the support head 22. The stepper motor 3 then drives the vertical can turntable 21 to rotate counterclockwise to lift the can. The rotation continues until the bottom of the can contacts the upper surface of the mounting frame 1, at which point the can stands upright. Subsequently, the support head 22 rotates further with the vertical can turntable 21 to detach from the can, completing the horizontal can conveying process. The paper can is uprighted, then rotated until the support head 22 protrudes out of the mounting bracket 1 again, the stepper motor 3 stops, and waits for the next paper can to be mounted before repeating the above paper can erection process; during the paper can erection process, since the paper can is generally relatively tall, when the paper can erection turntable 21 and the support head 22 drive the paper can to rotate, the paper can on the support head 22 will squeeze the previously erected paper can, forcing the previously erected paper can to move towards the upright paper can conveying mechanism, so that the upright paper can is conveyed away, and this process can be repeated to automatically erect the paper can.

[0036] In summary, compared with the prior art, this application has a stepper motor 3 and a can-standing assembly 2 on the mounting frame 1. The stepper motor 3 drives the can-standing assembly 2 to rotate counterclockwise, which can lift the paper can. The can-standing assembly 2 does not contact the packaging paper on the outer surface of the paper can, and there is no friction between them. This prevents the packaging paper on the surface of the paper can from being damaged by friction while the paper can is being stood upright, thus ensuring the production quality of the paper can. In addition, the mounting frame 1 and the stop bar 5 can be adjusted according to the usage requirements, which makes it convenient to limit the paper cans of different diameters and to stand the paper cans of different diameters upright.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
