When packing, the opening of the empty box faces the push plate, and the push plate pushes the bottle body into the empty box. The top of the bottle enters the empty box first, and then rotates 180 degrees after the packing is completed to seal the bottom of the box.

[0004] In the above patents and prior art, materials are mostly transported by pushing and conveyor belts. After the injection molded products are produced, the surface hardness is low and they will be damaged due to surface friction during the pushing process. When the injection molded products are transported by conveyor belts, the materials may collide with the guardrails on both sides of the conveyor belt and cause damage. Summary of the invention

[0009] The higher part of the conveying mechanism faces the opening at the top of the device body, and the lower part of the conveying mechanism faces the packaging box on the conveyor belt. After demolding, the injection molded product enters the interior of the supporting mechanism from the opening at the top of the device body, and then the supporting mechanism can move downward along the inclined angle of the conveying mechanism and flip along the outside of the conveying mechanism to place the injection molded product into the packaging box.

[0016] When the telescopic spring contacts the limiting mechanism, the telescopic spring contracts from the initial position toward the telescopic sleeve. When moving, the telescopic spring can drive the movable mounting seat to move synchronously, shortening the distance between the fixed mounting seat and the movable mounting seat.

[0026] Compared with the prior art, the present invention provides a fully automatic boxing device for an injection molding machine, which has the following beneficial effects:

[0027] 1. The fully automatic packing device of this injection molding machine allows the injection molded products to enter the storage net bag when they descend. The storage net bag descends under the force of gravity and drives the roller belt to rotate. At this time, the storage net bag and the injection molded products can continue to descend and flip along the direction of the roller belt. When the storage net bag flips, the injection molded products inside can be placed in the packaging box. During the descent of the injection molded products, the injection molded products are moved through the storage net bag made of relatively soft material, and the injection molded products are placed in the storage bin by flipping, which can effectively prevent the injection molded products from being damaged during the movement.

[0028] 2. The fully automatic packing device of the injection molding machine is provided with a plurality of bearing mechanisms outside the roller belt. The injection molded product is placed inside the bearing mechanism on one of the bearing mechanisms. The bearing mechanism can be lowered from the highest point to the lowest point. During the lowering process of the bearing mechanism, the roller belt can be driven to rotate. When the roller belt rotates, the bearing mechanism at the lower point can be raised to the higher point, thereby enabling the movement and packaging of the injection molded product to be cyclically performed.

[0029] 3. The fully automatic packing device of this injection molding machine can drive the roller belt to rotate when the injection molded product enters the carrying mechanism and descends. When the roller belt rotates, it can drive the telescopic connecting rod to contact the limit block and compress the telescopic spring. When the telescopic spring is compressed, it can drive the movable connecting rod to move in the direction close to the fixed connecting rod. When the movable connecting rod moves, the opening of the storage net bag can be narrowed. After the storage net bag is narrowed, the position of the injection molded product can be adjusted. Then the storage net bag puts the internal injection molded product into the packaging box. After the telescopic connecting rod is separated from the limit block, the telescopic spring rebounds. After the telescopic spring rebounds, it drives the movable connecting rod to move in the direction away from the fixed connecting rod. When the fixed connecting rod moves, the width of the opening of the storage net bag can be widened, thereby increasing the accuracy of the injection molded product entering the packaging box.

DETAILED DESCRIPTION

[0039] 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 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 creative work are within the scope of protection of the present invention.

[0040] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a fully automatic boxing device for an injection molding machine.

[0041] Example 1

[0042] See also Figure 1 - Figure 8 A fully automatic boxing device for an injection molding machine comprises a device body 1, a conveying mechanism 2, a limiting mechanism 4 and a conveyor belt 5. The conveying mechanism 2 is installed inside the device body 1, the limiting mechanism 4 is installed on the inner side wall of the device body 1, and the conveyor belt 5 is installed inside the device body 1. The device is characterized in that: a bearing mechanism 3 is installed outside the conveying mechanism 2, a box arranging rod 6 is installed on the top of the conveyor belt 5, and a packaging box 7 is placed on the top of the conveyor belt 5;

[0043] The conveying mechanism 2 is installed on the inner side wall of the device body 1. The conveying mechanism 2 is an inclined structure inside the device body 1. When the conveying mechanism 2 rotates, it can drive the carrying mechanism 3 to move.

[0044] Two limiting mechanisms 4 are installed inside the device body 1. The two limiting mechanisms 4 are installed on both sides of the conveying mechanism 2. The limiting mechanisms 4 are also inclined structures. The inclination angle of the limiting mechanisms 4 is smaller than the inclination angle of the conveying mechanism 2 on the inner side of the device body 1.

[0045] The higher part of the conveying mechanism 2 faces the opening at the top of the device body 1, and the lower part of the conveying mechanism 2 faces the packaging box 7 on the conveyor belt 5. After the injection molded product is demolded, it enters the interior of the supporting mechanism 3 from the opening at the top of the device body 1, and then the supporting mechanism 3 can move downward along the inclined angle of the conveying mechanism 2 and flip along the outside of the conveying mechanism 2 to place the injection molded product into the packaging box 7.

[0046] During operation, after the injection molded product is demoulded, it enters the carrying mechanism 3 from the opening at the top of the device body 1. After the carrying mechanism 3 carries the injection molded product, it drives the roller belt 23 to rotate under the action of gravity. When the roller belt 23 rotates, it can drive the carrying mechanism 3 to move. When driving the carrying mechanism 3 to move, the roller belt 23 can make the carrying mechanism 3 contact with the limiting mechanism 4, and when the carrying mechanism 3 continues to move, it can contact the auxiliary roller 24 and then flip along the roller belt 23. When the carrying mechanism 3 is flipped, the injection molded product is placed upside down in the packaging box 7. When one carrying mechanism 3 descends and drives the roller belt 23 to rotate, it can drive the carrying mechanism 3 below to rise. When one injection molded product drives the carrying mechanism 3 to descend, it can drive the carrying mechanism 3 below to rise, thereby realizing the cyclic lifting operation of the carrying mechanism 3. The carrying mechanism 3 adopts a storage net bag 34 made of a relatively soft material, which can effectively prevent the injection molded product from being damaged during the movement.

[0047] Example 2

[0048] The difference from the above embodiment is that, please refer to Figure 2 - Figure 6The conveying mechanism 2 includes an upper roller 21, a lower roller 22 and a roller belt 23. The upper roller 21 and the lower roller 22 are fixedly mounted on the inner side wall of the device body 1. The roller belt 23 is mounted on the outside of the upper roller 21 and the lower roller 22. An auxiliary roller 24 is rotatably mounted on the inner side of the lower roller 22. A fixed mounting seat 25 is fixedly mounted on the outside of the roller belt 23. A telescopic sleeve 26 is fixedly mounted on the top of the fixed mounting seat 25. A telescopic spring 28 is slidably mounted inside the telescopic sleeve 26. A telescopic connecting rod 27 is fixedly connected to one side of the telescopic sleeve 26, and a movable mounting seat 29 is fixedly connected to one end of the telescopic connecting rod 27.

[0049] The upper roller 21 and the lower roller 22 are fixedly installed on the front and rear sides of the device body 1. The outer sides of the two sets of upper rollers 21 and lower rollers 22 are connected by roller belts 23. Auxiliary rollers 24 are rotatably installed on the inner sides of the two lower rollers 22. Multiple fixed mounting seats 25 are fixedly installed on the outer sides of the roller belts 23.

[0050] The upper roller 21 is installed at a higher position inside the device body 1 , and the lower roller 22 is installed at a lower position inside the device body 1 .

[0051] The top of the fixed mounting seat 25 is connected to the top of the movable mounting seat 29 through the telescopic sleeve 26 and the telescopic spring 28, the bottom of the fixed mounting seat 25 is fixedly connected to the roller belt 23, and the surface of the movable mounting seat 29 does not contact the roller belt 23;

[0052] One end of the telescopic spring 28 is slidably installed inside the telescopic sleeve 26, and the other end of the telescopic spring 28 is fixedly connected to the movable mounting seat 29. One end of the telescopic connecting rod 27 is fixedly connected to the telescopic sleeve 26, and the other end of the telescopic connecting rod 27 is fixedly connected to the movable end of the telescopic spring 28.

[0053] The fixed mounting seat 25 and the movable mounting seat 29 can rotate around the upper roller 21 and the lower roller 22 through the roller belt 23. When the fixed mounting seat 25 and the movable mounting seat 29 rotate, they can drive the bearing mechanism 3 to move synchronously. During the movement of the fixed mounting seat 25 and the movable mounting seat 29, the movable end of the telescopic spring 28 contacts the limiting mechanism 4;

[0054] When the telescopic spring 28 contacts the limiting mechanism 4, the telescopic spring 28 contracts from the initial position toward the telescopic sleeve 26. When moving, the telescopic spring 28 can drive the movable mounting seat 29 to move synchronously, shortening the distance between the fixed mounting seat 25 and the movable mounting seat 29. After the telescopic spring 28 is separated from the limiting mechanism 4, the telescopic spring 28 returns to the initial position driven by the telescopic connecting rod 27.

[0055] When the carrying mechanism 3 descends, the roller belt 23 can be driven to rotate. When the roller belt 23 rotates, the fixed mounting seat 25 and the movable mounting seat 29 can be driven to move synchronously. When the roller belt 23 rotates, the telescopic connecting rod 27 can be driven to contact the limiting mechanism 4. After the telescopic connecting rod 27 contacts the limiting mechanism 4, the roller belt 23 continues to rotate and drives the telescopic connecting rod 27 to move in the direction of the telescopic sleeve 26. When the telescopic connecting rod 27 moves, the telescopic spring 28 can be compressed and the movable mounting seat 29 can be driven to move in the direction of the fixed mounting seat 25. Then the roller belt 23 continues to rotate to drive the telescopic connecting rod 27 to separate from the limiting mechanism 4. After the telescopic connecting rod 27 is separated from the limiting mechanism 4, the telescopic spring 28 rebounds. After the telescopic spring 28 rebounds, it drives the telescopic connecting rod 27 to move in the direction away from the telescopic sleeve 26. The roller belt 23 is driven to rotate cyclically by the descent of the injection molded product, thereby realizing the cyclic descent and packaging of the injection molded product.

[0056] Example 3

[0057] The difference from the above embodiment is that, please refer to Figure 3 - Figure 5 The bearing mechanism 3 includes a fixed connecting rod 31 and a movable connecting rod 32. The fixed connecting rod 31 is fixedly mounted on the top of the fixed mounting seat 25, and the movable connecting rod 32 is fixedly mounted on the top of the movable mounting seat 29. The fixed connecting rod 31 and the movable connecting rod 32 are both rotatably mounted with a rotating sleeve 33 on their exteriors, and a storage net bag 34 is fixedly connected to the bottom of the rotating sleeve 33.

[0058] The two ends of the fixed connecting rod 31 are respectively fixedly mounted on the top of the fixed mounting seats 25 on both sides, and the two ends of 32 are respectively fixedly mounted on the top of the movable mounting seat 29.

[0059] The two parallel sides of the storage net bag 34 are fixedly connected to the outside of the rotating sleeve 33. The movable mounting seat 29 can synchronously drive the movable connecting rod 32 and the fixed connecting rod 31 to move in the process of moving in the direction of the telescopic sleeve 26. When the movable connecting rod 32 moves in the direction of the fixed connecting rod 31, the width of the storage net bag 34 can be shortened.

[0060] After the injection molded product is placed inside the storage net bag 34, the roller belt 23 can be driven to rotate under the action of gravity. The roller belt 23 lowers the height of the injection molded product during the rotation process. During the rotation process of the roller belt 23, the telescopic spring 28 can contact the limit mechanism 4 to drive the movable connecting rod 32 to move in the direction of the fixed connecting rod 31, so as to adjust the position of the injection molded product.

[0061] When the storage net bag 34 drives the injection molded product to descend, the outside of the storage net bag 34 can contact the auxiliary roller 24. When the storage net bag 34 contacts the auxiliary roller 24, it can assist the storage net bag 34 to flip over. When the storage net bag 34 flips over, the injection molded product can be placed in the packaging box 7.

[0062] After the injection molded product is demoulded, it can enter the storage net bag 34 from the opening at the top of the device body 1. When the injection molded product enters the storage net bag 34 and moves downward, it can drive the roller belt 23 to rotate. When the roller belt 23 rotates, it can drive the telescopic connecting rod 27 to contact the limiting mechanism 4. When the telescopic connecting rod 27 contacts the limiting mechanism 4, it can drive the movable mounting seat 29 to move in the direction of the fixed mounting seat 25. When the movable mounting seat 29 moves in the direction of the fixed mounting seat 25, it can drive the movable connecting rod 32 to move in the direction of the fixed connecting rod 31. When the movable connecting rod 32 moves toward the direction of the fixed connecting rod 31, the width of the storage net bag 34 can be shortened to limit the position of the injection-molded product. When the storage net bag 34 continues to move and flips along the roller belt 23, the internal injection-molded product can be placed inside the packaging box 7. At this time, the storage net bag 34 is flipped inside and out. When the storage net bag 34 flips, the rotating sleeve 33 can be used to adapt to the flipping of the storage net bag 34. By using a storage net bag 34 made of a relatively soft material, the injection-molded product can be placed inside the packaging box 7 by flipping it, thereby effectively preventing the injection-molded product from being damaged during movement.

[0063] Example 4

[0064] The difference from the above embodiment is that, please refer to Figure 7 and Figure 8 The limiting mechanism 4 includes a limiting sleeve 41, which is fixedly mounted on the inner wall of the device body 1, and a limiting spring 42 is fixedly mounted inside the limiting sleeve 41, and a movable end of the limiting spring 42 is fixedly connected to a limiting block 43;

[0065] A sliding groove is provided on one side of the limiting sleeve 41 , and a protrusion is provided on the outside of the limiting block 43 . The protrusion on the outside of the limiting block 43 can pass through the sliding groove provided in the limiting sleeve 41 and contact the telescopic spring 28 .

[0066] The limiting sleeve 41 is fixedly mounted on the inner side wall of the device body 1 , and the inclination angle of the limiting sleeve 41 on the inner side wall of the device body 1 is smaller than the inclination angle of the roller belt 23 ;

[0067] The roller belt 23 can contact the limit block 43 when driving the telescopic connecting rod 27 to move. When the roller belt 23 continues to move, it drives the telescopic connecting rod 27 to contract and also synchronously drives the limit block 43 to move to compress the limit spring 42. The roller belt 23 can drive the telescopic connecting rod 27 to continue to move during the continued movement. When the roller belt 23 continues to move, it can drive the telescopic connecting rod 27 to separate from the movable connecting rod 32. After the telescopic connecting rod 27 is separated from the movable connecting rod 32, the telescopic spring 28 and the limit spring 42 rebound.

[0068] During the descending process of the carrying mechanism 3, the roller belt 23 is driven to rotate. When the roller belt 23 rotates, the telescopic connecting rod 27 can be driven to contact with the limit block 43. After the telescopic connecting rod 27 contacts with the limit block 43, the telescopic spring 28 and the limit spring 42 are compressed synchronously. During the compression process of the telescopic spring 28, the movable mounting seat 29 can be driven to move in the direction of the fixed mounting seat 25, and the movable connecting rod 32 can also be driven to move in the direction of the fixed connecting rod 31. When the movable connecting rod 32 moves, the opening of the storage net bag 34 can be narrowed. After the storage net bag 34 is narrowed, the position of the injection molded product can be adjusted. The position is adjusted, and after the injection molded product is placed in the packaging box 7, the telescopic connecting rod 27 is separated from the limit block 43. After the telescopic connecting rod 27 is separated from the limit block 43, the telescopic spring 28 and the limit spring 42 rebound synchronously. After the telescopic spring 28 rebounds, it drives the movable connecting rod 32 to move in the direction away from the fixed connecting rod 31. When the fixed connecting rod 31 moves, the width of the opening of the storage net bag 34 can be widened. During the descent of the injection molded product, the position of the injection molded product is limited by the contact between the fixed connecting rod 31 and the limit block 43, thereby increasing the accuracy of the injection molded product entering the packaging box 7.

[0069] While embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
