Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically to a clamping pusher used in cartoning machines. Background Art

[0002] A strip pack refers to a box into which multiple strip packs placed side by side are pushed together. Nowadays, the pushers are flat pushers that directly push the strip packs into the box.

[0003] Because carton packs are flat at both ends and bulging in the middle, they are quite fluffy and wide when multiple carton packs are placed side by side. In order to reduce the failure rate of cartoning, carton manufacturers usually design the width of the carton to be much larger than the packaged goods, resulting in waste of packaging materials. Utility Model Content

[0004] The purpose of this invention is to provide a clamping pusher for use in cartoning machines to solve the technical problem in the prior art where the strips of packaging are fluffy, resulting in larger packaging box sizes and waste of packaging materials.

[0005] To solve the above-mentioned technical problems, this utility model specifically provides a clamping pusher for use in a cartoning machine, including a chain circulating conveyor and a clamping mechanism and a pushing mechanism installed thereon;

[0006] The chain-type circulating conveyor is used to drive the clamping mechanism and the pushing mechanism to operate in a cyclical manner, and the operating speed is equal to the moving speed of the strip carrier.

[0007] The clamping mechanism is used to clamp the strips to compress and compact multiple loose strips.

[0008] The pushing mechanism is located inside the clamping mechanism and is used to push the compressed strip into the packaging box;

[0009] Multiple sets of the clamping mechanism and the pushing mechanism are installed on the chain circulating conveyor;

[0010] The clamping mechanism can follow the pushing mechanism into the packaging box to keep the strip package in a tight state before it enters the packaging box.

[0011] As a preferred embodiment of this utility model, the chain-type circulating conveyor is fixedly installed with multiple parallel fixed guide rails, and the clamping mechanism and the pushing mechanism are both slidably installed on the fixed guide rails.

[0012] As a preferred embodiment of the present invention, the clamping mechanism includes a first slider and two clamping plates slidably connected to the fixed guide rail. The clamping plates are fixedly connected to the first slider, and a first cam follower is provided below the first slider.

[0013] The first slider is equipped with an opening and closing control component for controlling the opening and closing of the clamping piece;

[0014] The pushing mechanism includes a second slider and a pusher that are slidably connected to the fixed guide rail. The pusher is fixedly connected to the second slider. A second cam follower is provided below the second slider. The pusher is located between the two clamping plates.

[0015] The chain-type circulating conveyor is equipped with a fixed lower guide plate, and the lower guide plate is provided with a first guide groove and a second guide groove.

[0016] The first guide groove cooperates with the first cam follower to control the clamping mechanism to slide back and forth;

[0017] The second guide groove cooperates with the second cam follower to control the forward and backward sliding of the pushing mechanism.

[0018] In a preferred embodiment of the present invention, both the first guide groove and the second guide groove include a forward section and a backward section, and the forward section and the backward section are smoothly connected.

[0019] As a preferred embodiment of the present invention, a horizontal section is further provided in the second guide groove between the forward section and the backward section;

[0020] When the second cam follower moves within the horizontal section, the front and rear positions of the pushing mechanism remain unchanged;

[0021] The position of the horizontal segment corresponds to the initial segment of the backward segment in the first guide groove, so that the clamping piece exits the packaging box before the pusher.

[0022] As a preferred embodiment of this utility model, the clamping control assembly includes a guide rod, a first spring, and a clamping control block;

[0023] The guide rod passes horizontally through the two clamping pieces so that the two clamping pieces can move closer to each other or further apart.

[0024] The two ends of the first spring are respectively connected to the two clamping plates to provide clamping force;

[0025] The clamping control block is slidably connected to the first slider, and the front sides of the clamping control block are set as inclined surfaces. The clamping control block can slide forward under the push-pull structure to squeeze and push the two clamping pieces apart.

[0026] As a preferred embodiment of this utility model, the push-pull structure includes a third cam follower fixedly installed on the top of the clamping control block;

[0027] A fixed upper guide plate is provided above the clamping control block, and a third guide groove is provided on the upper guide plate;

[0028] The third guide groove can be connected to the third cam follower to control the opening control block to move forward or backward;

[0029] The clamping control block is also connected to the upright on the fixed guide rail via a second spring, so that after the third cam follower disengages from the third guide groove, it pulls the clamping control block to reset.

[0030] As a preferred embodiment of the present invention, the third guide groove includes an opening section, a clamping section and a clamping holding section that are connected in sequence and smoothly.

[0031] Both the opening section and the clamping section correspond to the advancing ends of the first guide groove and the second guide groove, so as to complete the clamping before the strip is put into the box.

[0032] Compared with the prior art, this utility model has the following advantages:

[0033] The clamping pusher can compress the strips tightly before pushing them into the packaging box, reducing the width of the strip assembly and thus the width of the packaging box, saving packaging materials. Furthermore, the clamping mechanism enters the packaging box together with the pushing mechanism, keeping the strips in a tight state before entering the packaging box, ensuring successful box entry. In addition, the clamping mechanism exits the packaging box before the pushing mechanism to prevent the clamping mechanism from taking the strips out of the packaging box when it retracts.

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] like Figure 1-8 As shown, both the clamping mechanism 2 and the pushing mechanism 3 are from... Figure 1 Move from right to left. Figure 5 The upper guide plate in the middle is Figure 1 A bottom view of the upper guide rail plate.

[0053] A clamping pusher for use in a cartoning machine includes a chain circulating conveyor 1 and a clamping mechanism 2 and a pushing mechanism 3 mounted thereon;

[0054] The chain-type circulating conveyor 1 is used to drive the clamping mechanism 2 and the pushing mechanism 3 to operate in a cyclical manner, and the operating speed is equal to the moving speed of the strip carrier.

[0055] The clamping mechanism 2 is used to clamp the strips to compress and tighten multiple loose strips;

[0056] The pushing mechanism 3 is located inside the clamping mechanism 2 and is used to push the compressed strip into the packaging box;

[0057] Multiple sets of clamping mechanism 2 and pushing mechanism 3 are installed on chain-type circulating conveyor 1;

[0058] The clamping mechanism 2 can follow the pushing mechanism 3 into the packaging box to keep the strip package in a tight state before it enters the packaging box.

[0059] The above-mentioned clamping push technique is used as follows:

[0060] Start the chain-type circulating conveyor 1, so that multiple sets of clamping mechanisms 2 and pushing mechanisms 3 circulate at the same speed as the strip carrier, so that the clamping mechanisms 2 and pushing mechanisms 3 remain relatively stationary with respect to the strip;

[0061] The clamping mechanism 2 opens first, then moves forward to allow the strip to enter the clamping mechanism 2. Then the clamping mechanism 2 closes to compress the fluffy strip into a tight shape.

[0062] The clamping mechanism 2 and the pushing mechanism 3 move forward to push the strip into the packaging box;

[0063] The clamping mechanism 2 exits the packaging box before the pushing mechanism 3. That is, when the clamping mechanism 2 retracts, the pushing mechanism 3 remains stationary to prevent the clamping mechanism 2 from taking the strip out of the packaging box when it retracts.

[0064] After the clamping mechanism 2 exits the packaging box, the pushing mechanism 3 also exits the packaging box, and the clamping mechanism 2 and the pushing mechanism 3 are reset.

[0065] In summary, the clamping pusher can compress the strips tightly before pushing them into the packaging box, reducing the width of the strip assembly and thus the width of the packaging box, saving packaging materials. Furthermore, the clamping mechanism 2 enters the packaging box together with the pushing mechanism 3, keeping the strips in a compact state before entering the packaging box, ensuring successful box entry. Moreover, the clamping mechanism 2 exits the packaging box before the pushing mechanism 3 to prevent the clamping mechanism 2 from pulling the strips out of the packaging box when it retracts.

[0066] It should be noted that the clamping mechanism 2 can take many forms, such as the simplest form where the two clamping plates move closer or further apart when the cylinder is activated.

[0067] The forward or backward driving methods of the pushing mechanism 3 and the clamping mechanism 2 are also diverse, such as the simplest linear cylinder drive.

[0068] Furthermore, multiple parallel fixed guide rails 4 are fixedly installed on the chain-type circulating conveyor 1, and the clamping mechanism 2 and the pushing mechanism 3 are slidably installed on the fixed guide rails 4.

[0069] That is, the clamping mechanism 2 and the pushing mechanism 3 can slide forward or backward along the fixed guide rail 4 under the action of external force to complete the action of pushing the strip into the packaging box and out of the packaging box.

[0070] Furthermore, since the driving mechanisms such as cylinders require power, and the clamping mechanism 2 and the pushing mechanism 3, which operate continuously, are inconvenient to wire, an implementation method that does not require an additional power supply is proposed. The clamping mechanism 2 and the pushing mechanism 3 are configured as follows:

[0071] The clamping mechanism 2 includes a first slider 201 slidably connected to the fixed guide rail 4 and two clamping plates 202. The clamping plates 202 are fixedly connected to the first slider 201, and a first cam follower 203 is provided below the first slider 201.

[0072] The first slider 201 is equipped with an opening and closing control component 5 for controlling the opening and closing of the clamping piece 202;

[0073] The feeding mechanism 3 includes a second slider 301 and a pusher 302 that are slidably connected to the fixed guide rail 4. The pusher 302 is fixedly connected to the second slider 301. A second cam follower 303 is provided below the second slider 301. The pusher 302 is located between two clamping plates 202.

[0074] The chain-type circulating conveyor 1 is provided with a fixed lower guide plate 6, and the lower guide plate 6 is provided with a first guide groove 204 and a second guide groove 304.

[0075] The first guide groove 204 cooperates with the first cam follower 203 to control the back-and-forth sliding of the clamping mechanism 2;

[0076] The second guide groove 304 cooperates with the second cam follower 303 to control the forward and backward sliding of the pushing mechanism 3.

[0077] The working principles of the clamping mechanism 2 and the pushing mechanism 3 of the above structures are explained below:

[0078] When the clamping mechanism 2 moves to the top of the conveyor along with the chain-type circulating conveyor 1, the first cam follower 203 enters the first guide groove 204. As the first cam moves in the first guide groove 204, the first slider 201 and the clamping piece 202 are first pushed forward into the packaging box, and then pushed backward out of the packaging box and reset.

[0079] When the pushing mechanism 3 moves above the conveyor along with the chain-type circulating conveyor 1, the second cam follower 303 enters the second guide groove 304. As the second cam moves in the second guide groove 304, the second slider 301 and pusher 302 are first pushed forward into the packaging box, and then pushed backward out of the packaging box and reset.

[0080] Furthermore, both the first guide groove 204 and the second guide groove 304 include a forward section 231 and a backward section 232, and the forward section 231 and the backward section 232 are smoothly connected.

[0081] The details are as follows:

[0082] When the first cam follower 203 moves within the forward section 231 as the chain-type circulating conveyor 1 moves, the first slider 201 and the clamping piece 202 are pushed forward.

[0083] When the first cam follower 203 moves within the retracting section 232 as the chain-type circulating conveyor 1 moves, the first slider 201 and the clamping piece 202 are pushed backward.

[0084] When the second cam follower 303 moves within the forward section 231 as the chain-type circulating conveyor 1 moves, the second slider 301 and the pusher 302 are pushed forward.

[0085] When the second cam follower 303 moves within the retracting section 232 as the chain-type circulating conveyor 1 moves, the second slider 301 and the pusher 302 are pushed backward.

[0086] Furthermore, to ensure that the clamping mechanism 2 exits the packaging box before the pushing mechanism 3, the two guide slots are configured as follows:

[0087] In the second guide channel 304, a horizontal section 233 is also provided between the forward section 231 and the backward section 232;

[0088] When the second cam follower 303 moves within the horizontal section 233, the front and rear positions of the pusher mechanism 3 remain unchanged.

[0089] The position of the horizontal segment 233 corresponds to the initial segment of the retracting segment 232 in the first guide groove 204, so that the clamping piece 202 exits the packaging box before the pusher 302.

[0090] That is, when the first cam follower 203 and the second cam follower 303 simultaneously reach the foremost front end of the first guide groove 204 and the second guide groove 304 respectively, the second cam follower 303 enters the horizontal section 233 in the next step, while the first cam follower 203 enters the retraction section 232.

[0091] Furthermore, the clamping control assembly 5 includes a guide rod 501, a first spring 502, and a clamping control block 503;

[0092] The guide rod 501 horizontally passes through the two clamping pieces 202 so that the two clamping pieces 202 can move closer to each other or further away from each other;

[0093] The two ends of the first spring 502 are respectively connected to two clamping plates 202 to provide clamping force;

[0094] The clamping control block 503 is slidably connected to the first slider 201, and the front sides of the clamping control block 503 are set as inclined surfaces 504. The clamping control block 503 can slide forward under the push of the push-pull structure to squeeze and push the two clamping pieces 202 apart.

[0095] The rear end of the clamping plate 202 is provided with a fourth cam follower 205. When the clamping control block 503 moves forward, its inclined surface 504 presses the fourth cam follower 205 to reduce friction.

[0096] The clamping piece 202 is opened as follows:

[0097] The push-pull mechanism pushes the clamping control block 503 forward, causing the inclined surface 504 on the front side of the clamping control block 503 to squeeze the two clamping pieces 202, thereby overcoming the elastic force of the first spring 502 and causing the two clamping pieces 202 to move away from each other.

[0098] The clamping method of clamping piece 202 is as follows:

[0099] The push-pull mechanism pulls the clamping control block 503 backward, so that the inclined surface 504 on the front side of the clamping control block 503 no longer squeezes the clamping piece 202. Under the action of the contraction elastic force of the first spring 502, the two clamping pieces 202 slide closer to each other along the guide rod 501.

[0100] Furthermore, the push-pull structure includes a third cam follower 505 fixedly mounted on the top of the clamping control block 503;

[0101] A fixed upper guide plate 7 is provided above the clamping control block 503, and a third guide groove 506 is provided on the upper guide plate 7;

[0102] The third guide groove 506 can be connected to the third cam follower 505 to control the opening control block 503 to move forward or backward.

[0103] The clamping control block 503 is also connected to the upright rod 508 on the fixed guide rail 4 via the second spring 507, so that after the third cam follower 505 disengages from the third guide groove 506, the clamping control block 503 is pulled to reset.

[0104] At this point, the working principle of the push-pull structure is as follows:

[0105] When the third cam follower 505 enters the third guide groove 506, the clamping control block 503 slides back and forth under the drive of the third guide groove 506, so that the clamping piece 202 completes the opening and clamping actions before entering the packaging box.

[0106] After the third cam follower 505 disengages from the third guide groove 506, the second spring 507 can pull the clamping control block 503 to reset, so that the clamping control block 503 can enter the third guide groove 506 from the entrance of the third guide groove 506 in the next cycle.

[0107] Furthermore, the third guide groove 506 includes an opening section 509, a clamping section 5010, and a clamping holding section 5011 that are connected in sequence and smoothly.

[0108] The opening section 509 and the clamping section 5010 both correspond to the forward ends of the first guide groove 204 and the second guide groove 304, so as to complete the clamping before the strip is put into the box.
