Description

Technical Field

[0001] The present invention relates to the technical field of plastic shell packaging, in particular to a crawler-type automatic plastic shell packaging machine. Background Art

[0002] At present, the packaging of auto parts (brake pads, spark plugs) or daily necessities (razors, toothbrushes, pacifiers) is generally packaged by a plastic blister and a plastic bottom shell, with a paper card for product introduction placed between the two.

[0003] Generally, a crawler-type automatic plastic shell packaging machine first places the product inside the plastic shell packaging material and transmits it through the bottom of the automatic packaging machine via a crawler belt for continuous sealing. However, the device needs to align the position of the product when sealing. However, during the crawler belt transmission process, the position of the product will shift due to inertia. As a result, when closing the plastic shell package, the opening of the plastic shell package cannot be completely closed due to the deviation of the plastic shell package direction, thereby affecting the packaging effect of the automatic plastic shell packaging machine. Summary of the Invention

A mounting frame is fixedly connected to the front of the main body.

[0011] Furthermore, a connecting mechanism is provided on the outer wall of the supporting leg, which includes a connecting frame fixedly connected to the outer wall of the supporting leg, a placement frame fixedly connected to the bottom of the connecting frame, and a through hole is opened at the central axis of the top of the connecting frame.

[0012] Furthermore, the transmission mechanism also includes a placement plate, which is fixedly connected to one end of the bottom of the main body away from the extension plate. The top of the placement plate is fixedly connected to a motor, and the output end of the motor is fixedly connected to a transmission rod, which is arranged inside the crawler.

[0013] Furthermore, the limiting mechanism also includes a pressure plate, which is fixedly connected to the top of the splint. There are two adjusting rods, which are arranged corresponding to the two circular holes. The outer walls of the two adjusting rods are rotatably connected to a pull rack. A number of blocking blocks are fixedly connected to the side of the splint away from the slot, and the number of blocking blocks are distributed at equal distances. There are two limiting mechanisms, which are symmetrically distributed with the packaging rack as the center.

[0014] Furthermore, the pushing mechanism also includes a cylinder 1, which is fixedly connected to the outer wall of the extension plate. The output end of the cylinder 1 is fixedly connected to a connecting plate, and the bottom of the connecting plate is fixedly connected to the connecting bar.

[0015] Furthermore, the capping mechanism includes two slides, both of which are slidably connected to the inner walls of the two slide grooves, the top of the slide is fixedly connected to cylinder 2, the output end of cylinder 2 is fixedly connected to the hot press, and several output ends are arranged at the bottom of the hot press, and the several output ends are arranged corresponding to several packaging racks, and handles are fixedly connected to the left and right sides of the hot press.

[0016] Furthermore, a lifting mechanism is provided on the top of the placement rack, and the lifting mechanism includes a hydraulic cylinder, the hydraulic cylinder is fixedly connected to the top of the placement rack, and a clamping block is fixedly connected to the output end of the hydraulic cylinder.

[0017] Furthermore, spring holes are opened on the left and right sides of the card block, and support springs are fixedly connected inside the spring holes.

An extended support frame is fixedly connected to the side of the support spring away from the card block. There are several rising mechanisms, and the several rising mechanisms are arranged corresponding to the several packaging racks.

[0018] The present invention has the following beneficial effects:

[0019] (1) The present invention drives the transmission rod to rotate inside the conveying trough through the motor, drives the crawler to rotate on the outer wall of the rotating rod through the transmission rod, and drives several packaging racks to move at the same time. After the several packaging racks move evenly to the top of the crawler, the packaging rack below the crawler corresponds to the several lifting mechanisms and automatically stops the rotation of the motor. The hydraulic cylinder rises to push the plastic shell packaging box on the outer wall of the block to the inside of the several packaging racks. After the plastic shell packaging enters the inside of the packaging rack, it will be squeezed to cause the plastic shell packaging to deform, thereby clamping the plastic shell packaging inside the packaging rack. Then, the motor is started to drive the crawler to rotate and move the packaging rack with the plastic shell packaging to the top position corresponding to the output end of the hot press. Then, the product is placed inside the plastic shell packaging inside the packaging rack, and the plastic shell packaging is placed on the top of the plastic shell packaging. The plastic shell packaging inside the packaging rack is sealed and packaged by the pressing mechanism. During the crawler transmission process, the phenomenon of the direction deviation of the plastic shell packaging due to inertia is avoided, which prevents the opening of the plastic shell packaging from being completely closed, thereby avoiding affecting the packaging effect of the plastic shell automatic packaging machine.

[0020] (2) When the present invention puts an oversized plastic shell packaging box on the card block, the support spring and the extension bracket are extended so that the two extension brackets are against the inner wall of the plastic shell packaging box. The card slot is moved away from the circular hole in advance by rotating the adjustment rod, and the pull rack is pushed to make the adjustment rod slide on the inner wall of the circular hole, thereby driving the splint to adjust the spacing inside the packaging rack, so that plastic shell packaging boxes of various sizes can be placed and packaged. At the same time, the friction of the inner wall of the splint is increased by the blocking block to prevent the plastic shell packaging box from falling, thereby improving the practicality of the device.

[0021] (3) The pull handle of the present invention slides inside the slide groove through the slide, thereby driving the pull hot press to move to a position corresponding to the conveying groove, so that the output end of the hot press corresponds to the packaging rack on the top of the crawler, and the hot press is driven downward by the cylinder 2 to perform packaging. After packaging, the connection between the cylinder 1 and the connecting plate drives the connecting strip and several push rods to push, so that the push rods enter the packaging rack through the slide, thereby pushing the packaged products inside the packaging rack onto the extension plate for sorting, so as to facilitate the removal of the packaged products.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0035] Example 1

A capping mechanism 6 is provided on the top of the main body 1, and also comprises a transmission mechanism 3, which is arranged on the right side of the main body 1. The transmission mechanism 3 comprises a crawler 304, which is sleeved on the outer wall of the conveying trough 101. A plurality of packaging racks 305 are fixedly connected to the outer wall of the crawler 304. The plurality of packaging racks 305 are distributed at equal distances, and two circular holes 307 are provided on the left and right sides of the packaging racks 305. A sliding port 306 is provided on the rear wall of the packaging rack 305. The transmission rod 303 is driven by the motor 302 to rotate inside the conveying trough 101, and the crawler 304 is driven by the transmission rod 303 to rotate on the outer wall of the rotating rod 102, thereby driving the plurality of packaging racks 305 to move.

[0037] There are a number of rotating rods 102, which are evenly spaced. An extension plate 103 is fixedly connected to the side of the main body 1 away from the transmission mechanism 3. Two slide grooves 104 are defined on the top of the extension plate 103. The two slide grooves 104 are symmetrically distributed around the extension plate 103. Four support legs 105 are fixedly connected to the bottom of the main body 1. The four support legs 105 are evenly spaced. A mounting bracket 106 is fixedly connected to the front of the main body 1.

[0038] The outer wall of the support leg 105 is provided with a connecting mechanism 2, which includes a connecting frame 201, which is fixedly connected to the outer wall of the support leg 105, and a placement frame 202 is fixedly connected to the bottom of the connecting frame 201. A through hole 203 is opened at the central axis of the top of the connecting frame 201, and the rising mechanism 7 is fixed through the connecting frame 201 and the placement frame 202;

[0039] The transmission mechanism 3 also includes a placement plate 301, which is fixedly connected to the end of the bottom of the main body 1 away from the extension plate 103. The top of the placement plate 301 is fixedly connected to a motor 302, and the output end of the motor 302 is fixedly connected to a transmission rod 303. The transmission rod 303 is arranged inside the crawler 304. When a number of packaging racks 305 move evenly to the top of the crawler 304, the packaging racks 305 under the crawler 304 correspond to a number of lifting mechanisms 7 and the rotation of the motor 302 is automatically suspended.

[0040] A lifting mechanism 7 is provided on the top of the placement rack 202. The lifting mechanism 7 includes a hydraulic cylinder 701. The hydraulic cylinder 701 is fixedly connected to the top of the placement rack 202. The output end of the hydraulic cylinder 701 is fixedly connected to a clamping block 702. The hydraulic cylinder 701 rises to push the plastic shell packaging box on the outer wall of the clamping block 702 into the interior of several packaging racks 305. After the plastic shell packaging enters the interior of the packaging rack 305, it will be squeezed to cause the plastic shell packaging to deform, thereby clamping the plastic shell packaging inside the packaging rack 305.

[0041] When in use, the motor 302 drives the transmission rod 303 to rotate inside the conveying trough 101, and the transmission rod 303 drives the crawler 304 to rotate on the outer wall of the rotating rod 102, and at the same time drives several packaging racks 305 to move. When several packaging racks 305 move evenly to the top of the crawler 304, the packaging rack 305 under the crawler 304 corresponds to several lifting mechanisms 7 and automatically stops the rotation of the motor 302. The hydraulic cylinder 701 rises and pushes the plastic shell packaging box on the outer wall of the block 702 to the inside of several packaging racks 305. The plastic shell packaging will be squeezed after entering the interior of the packaging rack 305. The pressure causes the plastic shell package to deform, thereby clamping the plastic shell package inside the packaging rack 305, and then starting the motor 302 to drive the crawler to rotate 304 to move the packaging rack 305 with the plastic shell package to the top position corresponding to the output end of the hot press 603, and then put the product into the plastic shell package inside the packaging rack 305, and place the plastic shell package on the top of the plastic shell package, and press down the plastic shell package and the lid inside the packaging rack 305 through the cover pressing mechanism 6 to seal the package. During the transmission process of the crawler 304, the phenomenon of the plastic shell package being offset in direction due to inertia and the inability to completely close the opening of the plastic shell package is avoided.

The outer wall of the adjusting rod 403 is provided with a plurality of card slots 404, and the inner wall of the card slot 404 is engaged with the outer wall of the circular hole 307. By rotating the adjusting rod 403 in advance, the card slot 404 is separated from the circular hole 307, and the pull rack 405 is pushed to make the adjusting rod 403 slide on the inner wall of the circular hole 307, thereby driving the splint 401 to adjust the spacing inside the packaging rack 305, and increasing the friction of the inner wall of the splint 401 by the blocking block 406 to prevent the plastic shell packaging box from falling;

[0044] The pushing mechanism 5 includes a push rod 504, which is slidably connected to the inner wall of the sliding opening 306. The side of the push rod 504 away from the packaging rack 305 is fixedly connected to the connecting bar 503;
