[0003] At present, the strip bag packaging mainly uses an intermittent reciprocating box loading machine, and the intermittent reciprocating box loading machine mostly adopts a single pushing component.

[0004] Not only strip packages but also instruction manuals need to be loaded into the packaging box. However, since the strip packages are relatively soft, if the instruction manuals are directly pushed into the box by the strip packages, the instruction manuals will exert pressure on the strip packages, which may cause the strip packages to be in an irregular state after being loaded into the box. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a pushing component for a strip packaging box machine, so as to solve the technical problem in the prior art that since the strip packages are relatively soft, if the instruction manuals are directly pushed into the box by the strip packages, the instruction manuals will exert pressure on the strip packages, which may cause the strip packages to be in an irregular state after being loaded into the box.

[0065] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0066] A pusher component for a strip packaging box machine, characterized by comprising:

[0067] A pusher channel 6, one end of which is open and docked with the opening of the packaging box 7, and the other end is open and facing the action end of the pusher component 4. The channel size of the pusher channel 6 is equivalent to the opening size of the packaging box 7. "Equivalent" means that the channel size of the pusher channel 6 is the same as the opening size of the packaging box 7, or the channel size of the pusher channel 6 is slightly smaller than the opening size of the packaging box 7;

[0068] On one side of the pusher channel 6 close to the action end of the pusher component 4, a positioning structure for placing the instruction manual 9 and a platform 10 for placing the strip package 8 are sequentially arranged;

[0069] The pusher component 4 can reciprocate in the opening direction of the pusher channel 6 to push the strip package 8 and the instruction manual 9 into the packaging box 7;

[0070] Above the strip package 8, a pressing component 5 for pressing and flattening the strip package 8 is provided. The pressing component 5 is installed on the pusher component 4, and during pushing, the pressing component 5 can contact the instruction manual 9 prior to the strip package 8, that is, during the pushing process, when the pressing component 5 presses on the strip package 8, the front end of the pressing component 5 extends beyond the front end of the strip package 8.

[0071] Before pushing, the strip package 8, the instruction manual 9, the pusher channel 6, and the packaging box 7 are sequentially arranged. During the process of the pusher component 4 pushing the strip package 8 into the packaging box 7, the front end of the pressing component 5 will squeeze the middle position of the instruction manual 9 prior to the strip package 8, and the upper and lower sides of the instruction manual 9 will be squeezed by the edge of the pusher channel 6. The pressing component 5 cooperates with the pusher channel 6 to bend the instruction manual 9 into a U shape, so that the instruction manual 9 wraps around the strip package 8 and is pushed into the packaging box 7 together with the strip package 8 by the pusher component 4. It can also reduce the extrusion of the strip package 8 by the instruction manual 9, making the strip package 8 regular and flat after being put into the box.

[0072] Further, the positioning structure includes two U-shaped positioning strips 11 symmetrically arranged up and down. The positioning grooves of the two U-shaped positioning strips 11 are respectively used to clamp the upper and lower ends of the instruction manual 9 to keep the instruction manual 9 in an upright state waiting to be put into the box.

[0073] It is preferable that the upper and lower U-shaped positioning strips 11 are at an equal distance from the platform 10 for supporting the strip package 8, so that when the strip package 8 is pushed into the box, it can squeeze the middle position of the instruction manual 9. And the U-shaped positioning strips 11 and the opening of the pusher channel 6 are in the same plane

[0074] When the instruction manual 9 is squeezed by the strip package 8, under the action of the strip package and the two U-shaped positioning strips 11, it will be initially bent, and the upper and lower ends will disengage from the positioning grooves of the U-shaped positioning strips 11. Then, as the strip package 8 further moves into the material pushing channel 6, the instruction manual 9 will be bent into a U shape, so that the instruction manual 9 is wrapped outside the strip package 8 and is pushed into the packaging box 7 together with the strip package 8 by the material pushing assembly 4.

[0075] Furthermore, the material pushing channel 6 is arranged as a rectangular channel formed by overlapping four plate bodies.

[0076] Normally, a plurality of strip packages are contained in a packaging box, and a predetermined number of strip packages are pushed into the packaging box at one time by a strip packaging machine during packaging.

[0077] When pushing the strip package into the packaging box, since the strip package may be upturned and uneven, such upturned strip packages are relatively difficult to smoothly enter the packaging box.

[0078] Therefore, generally, a strip packaging machine needs to have two actions of pressing the material and pushing the material when pushing the material into the box. The current strip packaging machines use a double-cam structure or a double-servo motor to achieve these two actions, with more driving mechanisms and a more complex control program.

[0079] The utility model, through a clever mechanical design, can realize the pressing action while pushing the material through a single driving module. There are fewer driving structures, and only one driving module needs to be controlled, with a simple control program.

[0080] The pressing assembly 5 is installed on the front side of the material pushing assembly 4 and can move up and down under the drive of the cross module to achieve the pressing action while the material pushing assembly 4 pushes the material.

[0081] Furthermore, the technical solution of the utility model is elaborated below through a more specific embodiment:

[0082] A servo drive assembly 2 is fixedly connected to the frame 1, and a lifting base plate 301 is horizontally slidably connected to the frame 1. The servo drive assembly 2 is used to drive the lifting base plate 301 to slide forward or backward on the frame 1.

[0083] A lifting vertical plate 302 is vertically slidably connected to the lifting base plate 301. A material pushing assembly 4 for pushing the strip package is fixedly installed on the lifting vertical plate 302, and a pressing assembly 5 capable of moving up and down synchronously with the material pushing assembly 4 is installed on the front side of the material pushing assembly 4.

[0084] A first roller 303 is installed on the lifting vertical plate 302, and a pressing slide rail 304 that is in rolling cooperation with the first roller 303 is fixedly installed on the frame 1 to be used for restricting the movement path of the first roller 303.

[0085] The front part of the pressing slide rail 304 is a horizontal pressing section 305, and the rear end of the pressing horizontal section 305 is obliquely extended with a pressing inclined section 306; the pressing inclined section 306 can move the pressing assembly 5 downward to press the material when the pushing assembly 4 moves forward as a whole.

[0086] When pushing the strip pack 8 for boxing, the working process of the pushing component 4 mainly includes the pressing process and the pushing process, wherein the pressing process occurs along with the pushing process, specifically at the beginning stage of pushing, that is, the pushing component 4 moves forward but has not yet contacted the strip pack 8.

[0087] The details are as follows:

[0088] Pressing process:

[0089] The servo drive assembly 2 drives the lifting base plate 301 to move forward horizontally, and the lifting base plate 301 drives the lifting vertical plate 302, the pushing assembly 4 and the pressing assembly 5 to move forward synchronously.

[0090] After the movement starts, the first roller 303 first enters the pressing inclined section 306 of the pressing slide rail 304 . Under the constraint of the pressing inclined section 306 , the first roller 303 drives the lifting upright plate 302 to move downward relative to the lifting base plate 301 .

[0091] Since the pressing inclined section 306 is an inclined surface, the lifting vertical plate 302, the pushing assembly 4 and the pressing assembly 5 move obliquely downward during the forward movement of the first roller 303 in the pressing inclined section 306, so that the pressing assembly 5 completes the downward pressing action while moving forward with the pushing assembly 4. Before the pushing assembly 4 contacts the strip bag, it presses and flattens the strip bag from above to prevent it from warping, making it easier for the pushing assembly 4 to push multiple strip bags into the packaging box as a whole.

[0092] Pushing process:

[0093] As the first roller 303 enters the pressing horizontal section 305 from the pressing inclined section 306, the servo drive assembly 2 drives the lifting base plate 301, the lifting vertical plate 302, the pushing assembly 4 and the pressing assembly 5 to move forward horizontally synchronously, and the pushing assembly 4 pushes the strip package forward into the packaging box from the rear side of the strip package.

[0094] During the process of the pushing assembly 4 pushing the strip pack into the packaging box, the pressing assembly 5 is kept above the strip pack, maintaining the pressing state, but there is no further downward pressing action.

[0095] Reset process:

[0096] After the strip package is pushed into the packaging box, the servo drive assembly 2 runs in reverse, causing the material pressing assembly 5, the material pushing assembly 4, the lifting vertical plate 302, and the lifting base plate 301 to move backward for resetting, preparing for the next material pressing and pushing.

[0097] It should be added that the strip package 8 can be placed on the platform 10 manually or by a strip package placing mechanism. During the process of pushing the strip package 8, static clamping plates or dynamic clamping plates can be used to restrict the width of the strip package 8, making the strip package 8 also compact in the transverse direction and facilitating box insertion. The dynamic clamping plates refer to driving two clamping plates to approach each other through a cylinder or other driving parts to squeeze the strip package tightly.

[0098] In summary, through the installation and cooperation among the lifting base plate 301, the lifting vertical plate 302, the material pushing assembly 4, and the material pressing assembly 5 of the material pushing assembly 4, as well as the cooperation between the first roller 303 and the material pressing slide rail 304, only one servo drive mechanism provides power, enabling the material pressing assembly 5 to perform the material pressing action synchronously at the beginning stage of the material pushing action; there are few driving structures, only one driving module needs to be controlled, and the control program is simple.

[0099] The servo drive assembly 2 can be set in the form of a servo motor 204 cooperating with a lead screw 208, and the rotation of the lead screw 208 is used to drive the lifting base plate 301 to move horizontally forward or backward.

[0100] It can also be set in the form of a servo motor 204 cooperating with a conveyor belt. By fixing the lifting base plate 301 on the conveyor belt, the rotation of the conveyor belt is used to drive the lifting base plate 301 to move forward or backward.

[0101] Or a telescopic structure is used as the prime mover providing power.

[0102] The present utility model adopts the form of a servo motor 204 cooperating with a conveyor belt, and the specific structural composition is as follows:

[0103] The servo drive assembly 2 includes a horizontally arranged synchronous belt 201, a driving wheel 202 and an idler wheel 203 respectively arranged at both ends of the synchronous belt 201, and a servo motor 204 for driving the driving wheel 202;

[0104] The servo motor 204 is fixedly installed on the frame 1 through a motor mounting plate, and the idler wheel 203 is installed on the frame 1 through an idler wheel seat;

[0105] The lifting base plate 301 and the toothed belt pressing plate 205 are respectively arranged on both sides of a strand of the synchronous belt 201, and the toothed belt pressing plate 205 and the lifting base plate 301 are fixedly connected by screws, clamping the synchronous belt 201 tightly.

[0106] The driving wheel 202 and the idler wheel 203 should be respectively arranged at the front and rear ends of the frame 1. Considering that in the present utility model, the material pushing assembly 4, the material pressing assembly 5, etc. are all located at the rear end of the frame 1, therefore, the driving wheel 202 and the servo motor 204 are selected to be arranged at the front end of the frame 1.

[0107] Both the driving wheel 202 and the idler wheel 203 are provided with transmission teeth, and the inner side of the conveyor belt is also provided with teeth meshing with the driving wheel 202 and the idler wheel 203, making the transmission more precise. Cooperating with the servo motor 204, the material pushing action can be made more precise, avoiding the situations of excessive material pushing or the material not being pushed into the box.

[0108] The working principle of the servo drive assembly 2 is as follows:

[0109] The servo motor 204 drives the driving wheel 202 to rotate. The driving wheel 202 drives the idler wheel 203 to rotate through the belt. The driving wheel 202 and the idler wheel 203 keep the belt taut, and the belt drives the lifting base plate 301 to move during the movement process.

[0110] Furthermore, after the conveyor belt is used for a long time, a slack phenomenon will occur. In order to keep the conveyor belt taut and extend the working life of the conveyor belt, the present utility model takes the following measures:

[0111] Two straight slots 206 are opened on the idler wheel seat, and screws pass through the straight slots 206 to fix the idler wheel seat on the frame 1.

[0112] One side of the idler wheel seat is provided with a tensioning seat 207 fixedly installed on the frame 1. A horizontal lead screw 208 is rotatably connected to the tensioning seat 207 through a bearing, and the lead screw 208 is connected to a threaded hole opened on the idler wheel seat.

[0113] The specific method for tensioning the conveyor belt is as follows:

[0114] When the conveyor belt is slack, or after the conveyor belt is used for a certain period of time, loosen the fixing screws on the straight slots 206.

[0115] Since the idler wheel seat is threadedly connected with the lead screw 208, and the lead screw 208 is rotatably connected to the tensioning seat 207, therefore, after the fixing screws are loosened, the idler wheel seat will not move in position in a short time.

[0116] On the one hand, it can avoid the idler wheel 203 moving under the action of gravity and the tension of the conveyor belt after the screws are loosened, resulting in the separation of the idler wheel 203 from the conveyor belt; on the other hand, there is no need to use additional means to fix the idler wheel seat, improving convenience.

[0117] Since the idler wheel seat is arranged close to the frame 1, the idler wheel seat can be translated backward by rotating the lead screw 208. After the conveyor belt is tensioned, stop rotating the lead screw 208 and fix the idler wheel seat on the frame 1 again through the screws.

[0118] The fixing of the screw is more reliable and serves as the normal fixing method for the idler wheel seat. Although the fixing effect of the lead screw 208 is relatively weak, it can maintain the position of the idler wheel seat in a short time and can be used as a temporary fixing method for the idler wheel seat when adjusting the tension.

[0119] Preferably, in the present utility model, the sliding connection methods between the lifting base plate 301 and the frame 1 and between the lifting vertical plate 302 and the lifting base plate 301 both adopt the guide rail and slider structure, specifically as follows:

[0120] A horizontally arranged first linear slide rail 307 is fixedly installed on the frame 1, and a first slider 308 is correspondingly installed on the lifting base plate 301. The first slider 308 is sleeved on the first linear slide rail 307.

[0121] The above-mentioned sleeving means that the first slider 308 completely or partially wraps around the first linear slide rail 307.

[0122] A protruding anti - detachment strip 309 is provided on the first linear slide rail 307, and a corresponding anti - detachment groove 3010 is provided on the inner cavity wall of the first slider 308. The anti - detachment strip 309 and the anti - detachment groove 3010 are engaged with each other to prevent the first slider 308 from detaching from the side of the first linear slide rail 307.

[0123] On one side of the lifting base plate 301 away from the first linear slide rail 307, a vertically arranged second linear slide rail 3011 is fixedly installed, and a second slider 3012 is correspondingly provided on the lifting vertical plate 302. The connection method between the second linear slide rail 3011 and the second slider 3012 is the same as the connection method between the first linear slide rail 307 and the first slider 308.

[0124] Furthermore, in the present utility model, limit blocks 3013 are provided at both ends of the first linear slide rail 307 and the second linear slide rail 3011 to prevent the first slider 308 and the second slider 3012 from detaching.

[0125] Specifically, the above - mentioned limit blocks 3013 can be respectively fixedly installed on the frame 1 and the lifting base plate 301 by screws, and the limit blocks 3013 can be set as cylinders made of rubber.

[0126] Furthermore, the specific composition of the above - mentioned material pushing component 4 is as follows:

[0127] It includes a first material pushing rod 401 and a second material pushing rod 402 located below the first material pushing rod 401. Elongated plates extend upward at the front end of the first material pushing rod 401 and the rear end of the second material pushing rod 402.

[0128] The extension plate of the first pusher rod 401 is fixedly connected to the lifting vertical plate 302 through the pusher connecting block 403. The cooperation of the extension plate and the pusher connecting block 403 enables a certain space between the pusher assembly 4, the frame 1, and the lifting vertical plate 302, reserving sufficient installation space for the pressing assembly 5.

[0129] The extension plate of the second pusher rod 402 is fixedly connected to the rear end of the first pusher rod 401, creating a certain height difference between the second pusher rod 402 and the first pusher rod 401. This avoids the pusher plate 404 for pushing the strip package, which is installed at the front end of the second pusher rod 402, from being too close to the first pusher rod 401, preventing the first pusher rod 401 from contacting the strip package and affecting the pusher action.

[0130] Since the pressing needs to be carried out before the pusher action, that is, the pressing action of the pressing assembly 5 needs to be carried out before the pusher plate 404 contacts the strip package, so that the strip package is first pressed flat and then pushed into the packaging box. Therefore, the pressing assembly 5 is located on the front side of the pusher plate 404.

[0131] Furthermore, when pushing the strip package into the box, generally, the box opening of the packaging box is not easy to maintain in an open state. For this reason, the present utility model designs the pressing assembly 5 as follows, enabling the pressing assembly 5 to not only have the pressing function but also be used to open and maintain the packaging box in an open state, facilitating the pusher assembly to push the strip package into the packaging box.

[0132] Specifically as follows:

[0133] A third linear slide rail 405 is fixedly installed on the rod surface of the first pusher rod 401, and guide rods 407 are installed on the same side of the third linear slide rail 405 at both ends of the first pusher rod 401 through guide rod connecting blocks 406. A raised block 408 is provided on the front side of the upper part of the guide rod 407;

[0134] The pressing assembly 5 includes a third slider 501 slidably connected to the third linear slide rail 405, a sliding sleeve 502 slidably sleeved on the guide rod 407, and a pressing plate 503 for pressing located above the front side of the pusher plate 404. The pressing plate 503, the third slider 501, and the sliding sleeve 502 are fixedly connected to each other;

[0135] A fourth linear slide rail 504 is fixedly installed on one side of the sliding sleeve 502, and a fourth slider 505 is slidably connected to the fourth linear slide rail 504. The fourth slider 505 is located above the sliding sleeve 502;

[0136] A positioning rod 506 is vertically arranged between the fourth slider 505 and the sliding sleeve 502. The upper end of the positioning rod 506 penetrates through the fourth slider 505, and the lower end passes through the sliding sleeve 502 and extends to the guide rod 407. A spring 507 is sleeved outside the positioning rod 506, and both ends of the spring 507 abut against the fourth slider 505 and the sliding sleeve 502 respectively;

[0137] A second roller 508 is installed on the fourth slider 505, and the second roller 508 is in rolling cooperation with the spring pressing plate 509;

[0138] Both ends of the spring pressing plate 509 are fixedly installed on two stop rods 5010 at the bottom of the frame 1, and a limit block 3013 is also installed on the sliding sleeve 502. The stop rod 5010 can block the limit block 3013 to prevent the second roller 508 from disengaging from the spring pressing plate 509;

[0139] The middle of the spring pressing plate 509 is a horizontally arranged pressing horizontal section 5011. The rear end of the pressing horizontal section 5011 extends obliquely upward with a pressing inclined section 5012, and the front end of the pressing horizontal section 5011 extends obliquely upward with a separating inclined section 5013. And the inclined angle and the inclined length of the inclined surface of the separating inclined section 5013 are the same as those of the pressing inclined section 306;

[0140] When the second roller 508 is located at the pressing inclined section 5012 and the pressing horizontal section 5011, the spring 507 is in a compressed state, and the lower end of the positioning rod 506 abuts against the front side of the block 408. At this stage, the pressing component 5 moves synchronously with the pushing component 4;

[0141] When the second roller 508 is located at the high point of the separating inclined section 5013, the spring 507 is in a relaxed state, and the lower end of the positioning rod 506 is higher than the block 408. At this stage, the limit block 3013 on the sliding sleeve 502 is blocked by the front stop rod 5010, and the pressing plate 503 no longer moves forward with the pushing component 4;

[0142] When the pushing component 4 is reset backward, the front stop rod 5010 is used to push the pressing component 5 backward to reset.

[0143] The above is the structural composition of the pressing component 5. Next, the working principle of the pressing component 5 during pushing will be specifically described.

[0144] Initial stage: The pushing component 4, the lifting base plate 301, the lifting vertical plate 302, and the pressing component 5 are all at the rear. That is, the first roller 303 is located at the rear end of the pressing inclined section 306 of the pressing slide rail 304, and the second roller 508 is located at the rear end of the pressing inclined section 5012 of the spring pressing plate 509 (at this time, the spring 507 is in a compressed state, and the lower end of the positioning rod 506 abuts against the front side of the block 408 on the guide rod 407, so that the pressing component 5 can move synchronously with the pushing component 4 subsequently).

[0145] Pressing-down stage: The servo drive assembly 2 drives the lifting base plate 301, the lifting vertical plate 302, the pusher assembly 4, and the pressing component 5 to move forward. At this time, under the action of the pressing inclined section 306, the first roller 303 drives the lifting vertical plate 302, the pusher assembly 4, and the pressing component 5 to move downward as a whole (since the inclination angles and the lengths of the inclined surfaces of the pressing inclined section 306 and the pressing and combining inclined section 5012 are the same, the spring 507 remains in a compressed state during this stage, so that the lower end of the positioning rod 506 remains in contact with the block 408).

[0146] During this stage, the pressing component 5 completes the work of pressing and flattening the strip package, and at the same time, the pusher assembly 4 reaches the rear side of the strip package and is about to contact the strip package.

[0147] Horizontal forward movement stage: The first roller 303 enters the pressing horizontal section 305, and the second roller 508 enters the pressing and combining horizontal section 5011. During this stage, the pusher assembly 4 and the pressing component 5 move horizontally forward under the push of the servo drive assembly 2. The pusher assembly 4 starts to push the strip package forward, and the pressing component 5 stably presses above the strip package.

[0148] Stage of the strip package entering the box: The first roller 303 is in the pressing horizontal section 305, and the second roller 508 enters the separating inclined section 5013. During this stage, the positioning rod 506 moves upward under the elastic force of the spring 507, and the lower end of the positioning rod 506 disengages from the contact with the block 408 on the guide rod 407. At this time, the pusher assembly 4 moves forward alone to push the strip package into the packaging box and no longer drives the pressing component 5 to move synchronously.

[0149] Before pushing the strip package into the box, the front end of the pressing plate 503 of the pressing component 5 first pushes open the opening of the packaging box to prepare for the strip package to enter the box, and the pressing component 5 stays here to ensure that the strip package can smoothly enter the box.

[0150] Reset stage: After the strip package enters the box, the servo drive assembly 2 drives the lifting base plate 301, the lifting vertical plate 302, and the pusher assembly 4 to move backward. When the guide rod connecting block 406 at the front end of the first pusher rod 401 touches the sliding sleeve 502 of the pressing component 5 (at this time, the block 408 on the guide rod passes over the positioning rod 506 and is located behind the positioning rod 506), the pusher assembly 4 starts to drive the pressing component 5 to move backward synchronously. When the second roller 508 enters the pressing and combining horizontal section 5011 from the separating inclined section 5013, the spring 507 resumes the compressed state, and the positioning rod 506 abuts against the front of the block 408 again. Then continue to move backward and return to the position at the initial stage.

[0151] During the pushing process, the pressing plate 503 touches the instruction manual 9 before the strip package 8, and bends the instruction manual 9 in cooperation with the pushing channel. That is, during the pushing process, when the pressing plate 503 presses on the strip package 8, the front end of the pressing plate 503 extends beyond the front end of the strip package 8.

[0152] Further, to facilitate the pressing plate 503 to push open the opening of the packaging box, the pressing plate 503 is set as a flat thin plate with a narrow front and a wide rear, so that the narrow part at the front end of the pressing plate 503 can be inserted into the packaging box, and the wide part at the rear can ensure that the strip package is fully covered.

[0153] Further, the frame 1 includes a front side plate 101, a cross plate 102 installed in the middle of the front side plate 101, and a cover plate 103 installed on the cross plate 102. Two sets of pushing components 4 are symmetrically arranged on both sides of the cross plate 102, which can improve the efficiency of packing strip packaging boxes. And integrating the two pushing components 4 together occupies less space at the same packing speed.

The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
