[0001] The invention relates to the technical field of candy packaging and processing, and in particular to a turnover module of a packaging machine. Background Art

[0002] Cone-shaped chocolates are already common in the market today, available in boxes, bottles, and bulk. However, the corresponding equipment varies depending on the shape of the packaged product and the packaging process.

[0003] The conventional packaging machine process is: the belt conveyor transports the products to be packaged to the trough entrance in sequence, and then the material lever pushes them to the trough, and the trough rotates to the subsequent packaging fixture for subsequent product packaging. When the conical chocolate is fed, the bottom plane faces downward and the conical tip faces upward. In order to make the candy paper packaging more delicate, the plane of the conical chocolate needs to face upward when packaging the candy paper.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians of the art without making creative work are within the scope of protection of the present application.

[0028] A flip module of a packaging machine, such as Figure 1-Figure 6 As shown, it includes a claw transfer flipping mechanism, which is used for reciprocating and flipping the mechanical claws used to clamp the candies.

[0029] The claw transfer flipping mechanism includes: a power main shaft 15, an outer sleeve 30, and an intermediate sleeve 31; the power main shaft 15 is arranged horizontally, and both ends of the power main shaft 15 are rotatably connected to the box body, and a lever wheel is installed on the power main shaft 15, and the lever wheel is driven by the main power of the packaging machine; the power main shaft 15 is connected to the vertically arranged outer sleeve 30 through the first transmission module, and the lower part of the outer sleeve 30 is rotatably connected to the box body, and the upper part of the outer sleeve 30 is fixedly connected to the outer cover 25; the intermediate sleeve 31 is arranged inside the outer sleeve 30, and the outer sleeve 30 is connected to the intermediate shaft The sleeve 31 is rotatably connected, the bottom of the intermediate sleeve 31 is fixedly connected to the box body, the top of the intermediate sleeve 31 passes through the outer sleeve 30 and the top is fixedly connected to the third bevel gear 13, one end of the mechanical claw extends into the outer cover 25 and is meshed with the third bevel gear 13 through the bevel gear, and the mechanical claw is rotatably connected to the outer cover 25; the power spindle 15 drives the outer sleeve 30, the outer cover 25, and the mechanical claw to complete reciprocating rotation motion through the first transmission module. While completing the reciprocating rotation motion, the bevel gear of the mechanical claw moves along the third bevel gear 13 to complete the flipping.

[0030] Furthermore, the first transmission module includes a first cam 3, a roller assembly 4, a first gear 5, a second gear 6, an active bevel gear, and a second bevel gear 12. The first cam 3 is fixedly mounted on the power main shaft 15. A first rotating shaft is provided on one side of the power main shaft 15. A roller assembly 4 is fixedly connected to the first rotating shaft. The rollers on the roller assembly 4 cooperate with the cam grooves of the first cam 3. A first gear 5 is installed on the first rotating shaft. The first gear 5 is meshedly connected to the second gear 6 fixedly mounted on the second rotating shaft. An active bevel gear is also fixedly connected to the second rotating shaft. The active bevel gear is meshedly connected to the second bevel gear 12.

[0031] The power spindle 15 is driven by the power on the packaging machine through the synchronous pulley to drive the cam 3 to rotate, and the cam 3 drives the roller assembly 4 to swing back and forth. The roller assembly 4 uses the driven power to drive the first gear 5, the second gear 6, and the active bevel gear to drive the first bevel gear 12 and the outer sleeve 30 to rotate back and forth. Therefore, the reciprocating rotation of the first bevel gear 12 drives the upper mechanical claw to perform a left and right rotation reciprocating motion with a certain periodicity.

When the roller 18 no longer contacts the characteristic part of the second cam 11, the clamping claw is in a clamping state.

[0033] Specifically, the second transmission module includes a sixth gear 23, a third gear 7, a fourth gear 8, a fifth gear 9, a second active bevel gear, and a first bevel gear 10. The sixth gear 23 is fixed on the power main shaft 15. A third rotating shaft is arranged below the power main shaft 15. The third gear 7 is fixed on the third rotating shaft.

The material blocking block 1 is concave, and preferably, the material blocking block 1 is made of food-grade silicone material to avoid deformation of the chocolate candy due to squeezing.

[0035] Specifically, the third transmission module includes a sixth gear 23, a third gear 7, a third cam 20, and a first swing rod 21. The sixth gear 23 is fixed to the power main shaft 15, the third cam 20 and the third gear 7 are fixedly installed on the third rotating shaft, the third gear 7 is meshed with the sixth gear 23, the first swing rod 21 and the second swing rod 22 are respectively fixed on the fourth rotating shaft, and one end of the first swing rod 21 is provided with a roller that cooperates with the convex groove on the third cam 20; the power main shaft 15 drives the sixth gear 23, the third gear 7, and the third cam 20 to rotate, and the third cam 20 drives the first swing rod 21 to swing back and forth, and then drives the second swing rod 22 to swing back and forth.

[0036] In the flip module of the packaging machine of the utility model, the total power source of the claw transfer flip mechanism, the claw grabbing mechanism and the material blocking mechanism is the lever wheel on the power main shaft 15 and the power follower on the packaging machine, so as to achieve the coordination of the start and stop of each mechanism and the packaging machine. The claw grabbing mechanism drives the driving shaft 17 to complete the reciprocating linear motion through the second transmission module, the second cam 11, and the tooling 19 to realize the claw clamping of the chocolate. The claw transfer flip mechanism drives the mechanical claw to rotate to the subsequent packaging fixture and drives it to flip at the same time, so that the conical chocolate flips 180° to the plane facing up, which is conducive to packaging; the material blocking mechanism is released when the mechanical claw moves to the chocolate to grab it, which is convenient for the mechanical claw to grab it. After the mechanical claw is moved away, it protects the next product to prevent the product from falling.

[0037] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the utility model.
