Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of conveying positioning mechanism, in particular, to a conveying positioning mechanism of a double-piece box nailing machine. BACKGROUND

[0002] The box nailing machine is a device commonly used in the production process of packaging boxes, which is used to staple the bent paperboard together. A feeding rack is arranged outside the inlet end of the box nailing machine, and a conveying member is arranged on the feeding rack. A plurality of push blocks are arranged on the conveying member along the length direction. During production, the paperboard is placed on the conveying member and located between two adjacent push blocks. When the conveying member drives the push blocks to move towards the box nailing machine, the push blocks push the paperboard to move synchronously, and the paperboard is pushed out of the outlet end of the feeding rack and then conveyed into the box nailing machine. The position of the paperboard entering the box nailing machine is fixed, which cannot better meet the conveying needs of paperboards of different sizes. CONTENT OF THE UTILITY MODEL

[0003] To overcome the above defects, embodiments of the present disclosure provide a conveying positioning mechanism of a double-piece box nailing machine, which solves the technical problem that the position of the paperboard entering the box nailing machine is fixed in the related art, and cannot better meet the conveying needs of paperboards of different sizes.

[0004] According to one aspect, at least one embodiment of the present disclosure provides a conveying positioning mechanism of a double-piece box nailing machine, which is arranged at one end of a feeding rack close to a box nailing machine. The feeding rack has a conveying member for carrying and driving a paperboard to move towards the box nailing machine. The conveying positioning mechanism comprises:

[0005] A positioning seat is arranged on the feeding rack in a relative sliding manner and located above the conveying member. The positioning seat is used to move close to or away from the box nailing machine after sliding.

[0006] A pushing member is hingedly connected to the positioning seat at the upper end, and the hinge shaft is perpendicular to the conveying direction of the conveying member. The lower end of the pushing member is used to be flipped upwards under the pushing force of the conveying member and the paperboard, and abuts against the paperboard. The pushing member is configured to convey the paperboard through the lower end of the pushing member until the lower end of the pushing member is separated from the paperboard.

[0007] A limiting stopper is arranged on the positioning seat and located on the side of the pushing member away from the box nailing machine, which is used to limit the rotation of the pushing member, so that the pushing member can push the paperboard when moving towards the box nailing machine.

[0008] For example, in the conveying positioning mechanism of the double-piece box nailing machine provided by at least one embodiment of the present disclosure, the limiting stopper and the positioning seat are detachably connected.

[0009] For example, in at least one embodiment of the present disclosure, a conveying and positioning mechanism for a double-piece nailing machine further includes:

[0010] A guide rail is provided on the feed frame, and the length direction of the guide rail is the same as the conveying direction of the conveying component.

[0011] A slider, which is slidably connected to the guide rail;

[0012] A support beam is provided on the slider, and the length direction of the support beam is perpendicular to the length direction of the guide rail. A positioning seat is provided on the support beam. There are multiple positioning seats, and all the positioning seats are arranged along the length direction of the support beam. Each positioning seat is provided with both the pusher and the limiting stop.

[0013] For example, in at least one embodiment of the present disclosure, a conveying and positioning mechanism for a double-piece nailing machine is provided, which further includes a first lead screw. The first lead screw is rotatably mounted on the guide rail, and the length direction of the first lead screw is the same as the length direction of the guide rail. The slider is threadedly connected to the first lead screw.

[0014] For example, in at least one embodiment of the present disclosure, a conveying and positioning mechanism for a double-piece nailing machine is provided, which further includes a rotary drive mechanism. The rotary drive mechanism is disposed on the guide rail or is used to be disposed on the feeder frame, and the rotary drive mechanism is connected to the first lead screw drive.

[0015] For example, in a double-piece nail box conveying and positioning mechanism provided in at least one embodiment of this disclosure, the rotary drive mechanism is a servo motor.

[0016] For example, in a double-piece nail box conveying and positioning mechanism provided in at least one embodiment of this disclosure, the positioning seat is slidably disposed on the support beam, the sliding direction of the positioning seat is the same as the length direction of the support beam, the number of positioning seats is two, and the slider is located between the two positioning seats.

[0017] For example, in at least one embodiment of the present disclosure, a conveying and positioning mechanism for a double-piece nailing machine further includes:

[0018] A positioning beam is provided, which is slidably mounted on the feeder frame and the sliding direction is perpendicular to the length direction of the guide rail. The positioning seat is mounted on the positioning beam.

[0019] The second lead screw is rotatably mounted on the feeder frame. The length direction of the second lead screw is perpendicular to the length direction of the guide rail. The positioning beam is threadedly connected to the second lead screw, and the positioning beam is connected to the second lead screw in a one-to-one correspondence.

[0020] For example, in at least one embodiment of the present disclosure, a double-piece nail box conveying and positioning mechanism is provided, wherein the positioning beam has positioning holes, and the double-piece nail box conveying and positioning mechanism further includes:

[0021] An adjusting member is disposed on the positioning seat and located between the positioning seat and the positioning beam. The length direction of the adjusting member is the same as the length direction of the guide rail. The adjusting member has multiple adjusting holes, and all the adjusting holes are arranged along the length direction of the adjusting member.

[0022] A locking component, one end of which passes through the positioning hole and is threadedly connected to the adjustment hole, and the other end of which is located on the side of the positioning beam away from the adjustment component.

[0023] For example, in at least one embodiment of the present disclosure, a double-piece nailing machine conveying and positioning mechanism is provided, wherein the double-piece nailing machine conveying and positioning mechanism further includes a handle, and the handle is connected to the other end of the locking member.

[0024] The beneficial effects of the embodiments disclosed herein are as follows: Initially, the upper end of the pusher is hinged to the positioning seat, and the lower end hangs down naturally. The cardboard is placed on the conveyor and positioned between two adjacent sets of push blocks. When the conveyor drives the push blocks to move toward the nailing machine, the push blocks push the cardboard to move synchronously. After the cardboard contacts the pusher, the conveyor continues to drive the cardboard toward the nailing machine. The cardboard will generate a thrust on the lower end of the pusher. Under the action of this thrust, the lower end of the pusher will rotate upward around the hinge axis between it and the positioning seat, thereby abutting against the cardboard. At this time, the positioning seat and the pusher remain stationary in their current positions. The cardboard continues to move toward the nailing machine between the lower end of the pusher and the conveyor. When the lower end of the pusher separates from the cardboard, the lower end of the pusher is located between the cardboard and the limiting stop. At this time, the positioning seat slides toward the nailing machine. Under the limiting action of the limiting stop, the pusher moves toward the nailing machine together with the positioning seat and the limiting stop, pushing the cardboard into the nailing machine. The sliding distance of the positioning seat can be adjusted according to the size of the cardboard, thereby adjusting the pushing distance of the pusher and accurately pushing the cardboard to the designated position, which can better meet the conveying needs of cardboard of different sizes.

[0032] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0033] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

[0037] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] like Figures 1-5As shown, it illustrates a double-sheet nailing machine conveying and positioning mechanism in one embodiment of the present disclosure. The mechanism is set at one end of the feeding frame 16 near the nailing machine 18. The feeding frame 16 has a conveying member 17, which carries and drives the cardboard 19 toward the nailing machine 18. Each conveying member 17 has multiple paddles 20 arranged along its length. When the conveying member 17 moves, the paddles 20 can push the cardboard placed on the conveying member 17 to move. The positioning seat 1 is slidably mounted on the feeder frame 16 and located above the conveyor 17. After sliding, the positioning seat 1 is used to move closer to or further away from the nailing machine 18. The positioning seat 1 provides support and positioning for the pusher 2 and the limiting stop 3. The upper end of the pusher 2 is hinged to the positioning seat 1, and the hinge axis is perpendicular to the conveying direction of the conveyor 17. The lower end of the pusher 2 is used to flip upward under the pushing force of the conveyor 17 and the cardboard 19 and abut against the cardboard 19. The pusher 2 is configured so that the cardboard 19 is conveyed through the lower end of the pusher 2 until the lower end of the pusher 2 separates from the cardboard 19. The limiting stop 3 is mounted on the positioning seat 1 and located on the side of the pusher 2 away from the nailing machine 18. It is used to restrict the rotation of the pusher 2 so that when the pusher 2 moves toward the nailing machine 18, it can push the cardboard 19 and push the cardboard 19 into the nailing machine 18.

[0039] For example, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, taking the conveyor 17 conveying in the front-to-back direction and the stapling machine 18 located in front of the feed frame 16 and the conveyor 17 as an example, the cardboard 19 is placed on two adjacent conveyors 17. The pusher 2 is located in front of the limit stop 3. Initially, the lower end of the pusher 2 hangs down naturally. The cardboard 19 is placed on the conveyor 17 and positioned between two adjacent sets of levers 20. When the conveyor 17 moves, it drives the levers 20 towards the stapling machine 18. The levers 20 push the cardboard 19 to move synchronously. After the cardboard 19 contacts the pusher 2, the conveyor 17 continues to move the cardboard 19 towards the stapling machine 18. The cardboard 19 generates a thrust on the lower end of the pusher 2. Under this thrust, the lower end of the pusher 2 rotates upward around its hinge axis with the positioning seat 1. This allows the cardboard 1 to come into contact with the cardboard 19. At this point, the positioning seat 1 and the pusher 2 remain stationary. The cardboard 19 continues to move towards the stapler 18 between the lower end of the pusher 2 and the conveyor 17. Once the lower end of the pusher 2 separates from the cardboard 19, it is positioned between the cardboard 19 and the limiting stop 3. At this point, the positioning seat 1 slides towards the stapler 18. Under the restraint of the limiting stop 3, the pusher 2 moves towards the stapler 18 along with the positioning seat 1 and the limiting stop 3, pushing the cardboard 19 into the stapler 18. The sliding distance of the positioning seat 1 can be adjusted according to the size of the cardboard 19, thereby adjusting the pushing distance of the pusher 2 to accurately push the cardboard 19 to the designated position, better meeting the conveying needs of cardboard 19 of different sizes.

[0040] In some examples, the limit stop 3 and the positioning seat 1 are detachably connected. By using bolts or slots, the limit stop 3 can be quickly installed onto or removed from the positioning seat 1, making it easy to replace the limit stop 3 with one of suitable size and shape. This changes the swing angle of the pusher 2, improving the equipment's adaptability to various working conditions and enhancing its versatility.

[0041] In some examples, such as Figure 3 , Figure 4 and Figure 5As shown, a double-piece nail box conveying and positioning mechanism further includes a guide rail 4, a slider 5, and a support beam 6. The guide rail 4 is mounted on the feeding frame 16, and its length direction is the same as the conveying direction of the conveying component 17, both being arranged along the front-to-back direction, providing precise linear motion guidance for the slider 5 and the support beam 6. The slider 5 is slidably connected to the guide rail 4. The support beam 6 is mounted on the slider 5 and can move synchronously and in the same direction as the slider 5. The length direction of the support beam 6 is perpendicular to the length direction of the guide rail 4, that is, the length direction of the support beam 6 is arranged along the left-to-right direction. The positioning seat 1 is mounted on the support beam 6. There are multiple positioning seats 1, all of which are arranged along the length of the support beam 6. Each positioning seat 1 is equipped with a pusher 2 and a limit stop 3. Multiple positioning seats 1, pushers 2 and limit stops 3 can work together to operate multiple sets of cardboard 19 at the same time. For example, when two cardboard 19 need to be stapled together, only two positioning seats 1 need to be set on the support beam 6. The pusher 2 on each positioning seat 1 is used to push one of the cardboard 19. This can meet the high-efficiency production needs of double-piece nailing machines, reduce the time interval of cardboard 19 conveying and positioning, and improve production efficiency.

[0042] In some examples, a double-piece nail box conveying and positioning mechanism also includes a first lead screw 7, which is rotatably mounted on a guide rail 4. The length direction of the first lead screw 7 is the same as the length direction of the guide rail 4, both being arranged in the front-back direction. The slider 5 is threadedly connected to the first lead screw 7.

[0043] like Figure 4 and Figure 5 As shown, when the first lead screw 7 rotates, since the slider 5 is threadedly connected to the first lead screw 7, according to the lead screw transmission principle, the slider 5 cannot rotate with the first lead screw 7. It can only move linearly along the axis of the first lead screw 7, that is, move forward or backward. This drives the support beam 6, the positioning seat 1, the pusher 2, and the limit stop 3 to move forward or backward. After the first lead screw 7 stops, the slider 5 can stay in the current position. By controlling the rotation angle and number of rotations of the first lead screw 7, the position of the slider 5 can be precisely adjusted, thereby precisely controlling the position of the support beam 6 and the positioning seat 1. This allows the distance that the pusher 2 pushes the cardboard 19 can be precisely set according to the requirements, which can better meet the requirements of different sized cardboard 19 for pushing accuracy and improve the quality of nailing boxes. There is no need to set a separate locking and positioning structure for the slider 5, making the structure simpler, the operation more convenient and quick, and saving time and effort.

[0044] In some examples, such as Figure 4As shown, a double-piece nail box conveying and positioning mechanism also includes a rotary drive mechanism 8. The rotary drive mechanism 8 is mounted on the guide rail 4 or on the feeding frame 16. If it is directly mounted on the guide rail 4, power can be transmitted nearby, reducing energy loss in the transmission components. If it is mounted on the feeding frame 16, the structure of the feeding frame 16 can be used for stable installation, and it can also effectively drive the first lead screw 7. As a power source, the rotary drive mechanism 8 is connected to the first lead screw 7, transmitting its own power output to the first lead screw 7, driving the first lead screw 7 to rotate. This enables automated control of the movement of the slider 5, eliminating the need for manual rotation of the first lead screw 7, improving production efficiency and reducing manual labor intensity.

[0045] In some examples, the rotary drive mechanism 8 is a servo motor. The servo motor has high-precision position control, speed control, and torque control capabilities. By receiving electrical signals from the control system, it can precisely control the rotation angle and speed. After being connected to the first lead screw 7, it can precisely drive the first lead screw 7 to rotate according to a preset program. This can further improve the movement accuracy of the positioning seat 1. For cardboard 19 of different sizes, the servo motor can quickly and accurately adjust the pushing position of the pusher 2, ensuring that the cardboard 19 accurately reaches the designated position within the stapling machine 18 each time, further improving the consistency and quality of stapling. At the same time, the servo motor has a fast response speed, meeting the needs of frequent adjustments to the positioning seat 1 during high-speed production, thus improving production efficiency.

[0046] In some examples, such as Figure 3 , Figure 4 and Figure 5 As shown, the positioning seat 1 is slidably mounted on the support beam 6. The sliding direction of the positioning seat 1 is the same as the length direction of the support beam 6. The positioning seat 1 can slide along the length direction (i.e., the left and right direction) of the support beam 6. There are two positioning seats 1. The slider 5 is located between the two positioning seats 1. By changing the position of the positioning seat 1 on the support beam 6, the distance between the two adjacent positioning seats 1 can be changed, which can meet the needs of simultaneous conveying and positioning of double-sided cardboard 19 of different widths. This can improve the adaptability of the equipment to changes in cardboard size, reduce the trouble of replacing a large number of parts due to changes in cardboard size, and enhance the versatility of the equipment.

[0047] In some examples, a double-piece nail box conveying and positioning mechanism also includes a positioning beam 9 and a second lead screw 10. The positioning beam 9 is slidably mounted on the feed frame 16, and the sliding direction is perpendicular to the length direction of the guide rail 4, that is, the positioning beam 9 can slide in the left and right direction. The positioning seat 1 is mounted on the positioning beam 9, and the positioning seat 1 can slide synchronously in the left and right direction with the positioning beam 9, thereby changing the distance between the two positioning seats 1.

[0048] like Figure 3 and Figure 4As shown, the second lead screw 10 is rotatably mounted on the feed frame 16. The length direction of the second lead screw 10 is perpendicular to the length direction of the guide rail 4. The positioning beam 9 is threadedly connected to the second lead screw 10. The positioning beam 9 and the second lead screw 10 are connected in a one-to-one correspondence, that is, the second lead screw 10 on the left is threadedly connected to the positioning beam 9 on the left, and the second lead screw 10 on the right is threadedly connected to the positioning beam 9 on the right. When the second lead screw 10 is rotated, the positioning beam 9 will slide along the length direction of the support beam 6, that is, move to the left or right. After the second lead screw 10 stops rotating, the positioning beam 9 will stay in the current position. There is no need to set a separate locking and positioning structure for the positioning beam 9, which makes the structure simpler, the operation more convenient and quick, and saves time and effort.

[0049] In some examples, the positioning beam 9 has positioning holes 11. A double-piece nail box conveying positioning mechanism also includes an adjusting member 12 and a locking member 13. The adjusting member 12 is set on the positioning seat 1 and is located between the positioning seat 1 and the positioning beam 9. That is, the positioning seat 1, the adjusting member 12, and the positioning beam 9 are arranged in order from bottom to top. The length direction of the adjusting member 12 is the same as the length direction of the guide rail 4. That is, the length direction of the adjusting member 12 is set along the front-back direction. The adjusting member 12 has multiple adjusting holes 14. All the adjusting holes 14 are arranged along the length direction of the adjusting member 12, that is, along the front-back direction. One end of the locking member 13 passes through the positioning hole 11 and is threadedly connected to the adjusting hole 14. The other end of the locking member 13 is located on the side of the positioning beam 9 away from the adjusting member 12.

[0050] like Figure 3 , Figure 4 and Figure 5 As shown, the adjusting member 12 is located between the positioning seat 1 and the positioning beam 9. By selecting different adjusting holes 14 to align with the positioning hole 11, and then threading the lower end of the locking member 13 through the positioning hole 11 and connecting it with the adjusting hole 14, the relative position of the adjusting member 12 and the positioning beam 9 can be fixed. By changing the front and rear position of the adjusting member 12, the initial position of the positioning seat 1 and the pushing member 2 in the front and rear direction can be changed, which can better achieve accurate positioning of the cardboard 19.

[0051] In some examples, such as Figure 3 , Figure 4 and Figure 5 As shown, a double-piece nail box machine conveying and positioning mechanism also includes a handle 15. The handle 15 is connected to the other end (i.e., the upper end) of the locking member 13. The handle 15 and the locking member 13 are set vertically. The operator can easily and quickly tighten or loosen the locking member 13 by holding the handle 15 and rotating it, so as to realize the connection or separation of the adjusting member 12 and the positioning beam 9. This can reduce the difficulty of operation and make the adjustment of the equipment more convenient.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
