Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a packaging machine with a feeding structure. Background Technology

[0002] Packaging machines are key equipment for automating product packaging and are widely used in industries such as food and pharmaceuticals. In traditional pastry packaging production, pillow-type packaging machines are often used to seal pastries. Their internal conveyor belts are responsible for not only feeding the pastries to be packaged into the packaging mechanism but also conveying the packaged products out of the machine.

[0003] In existing technology, packaged products are usually scattered in plastic baskets placed below the conveyor belt. Operators need to manually replace the heavy plastic baskets full of products with empty ones. This process has obvious drawbacks: manual handling of heavy baskets is labor-intensive, inefficient, and slow to replace. A large number of products will be scattered on the ground and need to be collected manually. In order to solve the above problems, we propose a packaging machine with a feeding structure. Utility Model Content

[0004] The main objective of this invention is to provide a packaging machine with a feeding structure, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A packaging machine with a feeding structure includes a packaging machine body, a mounting base plate, and a controller. A placement tray is mounted on the upper end of the mounting base plate via a rotating shaft. The placement tray is provided with a receiving mechanism for receiving products. The receiving mechanism includes multiple collection frames placed on the placement tray. A first motor is fixedly connected to the upper end of the mounting base plate. A first gear and a second gear are fixedly connected to the output shaft of the first motor and the side wall of the rotating shaft, respectively. Multiple limiting strips are fixedly connected to the upper end of the placement tray. Multiple limiting mechanisms for restricting the movement of the collection frames are provided on the upper end of the placement tray.

[0007] Preferably, the limiting mechanism includes a stop bar that extends through the upper end of the placement plate, and the stop bar has an L-shaped cross-section.

[0008] Preferably, a mounting frame is fixedly connected to the side wall of the mounting base plate, a hydraulic cylinder is fixedly connected to the top of the mounting frame, a mounting frame is fixedly connected to the output end of the hydraulic cylinder, a second motor is fixedly connected to the side wall of the mounting frame, a reciprocating screw is fixedly connected to the output shaft of the second motor, and a limit plate is provided on the reciprocating screw.

[0009] Preferably, a vertical plate is fixedly connected to the top of the mounting bracket, two cylinders are fixedly connected to the side wall of the vertical plate, and a push plate is fixedly connected to the output end of the cylinders.

[0010] Preferably, a plurality of support rods are fixedly connected to the lower end of the placement tray, the plurality of support rods are arranged at equal intervals, and the lower end of the support rods is provided with ball bearings.

[0011] Preferably, the mounting base plate has connecting plates on both sides, the connecting plates are fixedly connected to the main body of the packaging machine, and the side walls of the connecting plates are provided with multiple bolts.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This device is equipped with a receiving mechanism. When a collection box is full of products, the first motor drives the placement plate to rotate, automatically switching the empty collection box to the receiving position. There is no need for manual stopping of the machine to change the box, which makes the packaging process continuous and improves production efficiency.

[0014] 2. This device is equipped with a limiting mechanism, which can accurately fix the position of the collection frame by means of a limiting strip and an L-shaped stop bar, preventing displacement during rotation, thereby increasing the rotation speed of the placement tray and increasing the speed of collection frame replacement.

[0015] 3. This device is equipped with hydraulic cylinders, reciprocating screws, etc. The hydraulic cylinders in the mounting frame can drive the mounting blocks to move up and down. When the second motor drives the reciprocating screws to rotate, the products falling into the frame are automatically dispersed, avoiding manual pushing of the piled products, reducing manpower input and ensuring that the products are stacked evenly.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-6 As shown, a packaging machine with a feeding structure includes a packaging machine body 1, a mounting base plate 3 and a controller 19. The packaging machine body 1 is a pillow-type packaging machine in the prior art, which is the prior art for packaging pastries, so it will not be described in detail. A placement tray 5 is mounted on the upper end of the mounting base plate 3 through a rotating shaft 4. The rotating shaft 4 is rotatably connected to the mounting base plate 3, and the rotating shaft 4 is fixedly connected to the placement tray 5.

[0025] The placement tray 5 is equipped with a receiving mechanism for receiving products. The receiving mechanism includes multiple collection frames 6 placed on the placement tray 5. The collection frames 6 are plastic baskets used in production lines in the prior art. A first motor 12 is fixedly connected to the upper end of the mounting base plate 3. A first gear and a second gear are fixedly connected to the side wall of the output shaft and the rotating shaft 4 of the first motor 12, respectively. Multiple limiting strips 8 are fixedly connected to the upper end of the placement tray 5.

[0026] The upper end of the placement tray 5 is provided with multiple limiting mechanisms to restrict the movement of the collection box 6. The limiting mechanism includes a stop bar 9 that runs through the upper end of the placement tray 5. The stop bar 9 has an L-shaped cross section.

[0027] In this utility model, a mounting frame 7 is fixedly connected to the side wall of the mounting base plate 3. A hydraulic cylinder 10 is fixedly connected to the top of the mounting frame 7. The hydraulic cylinder 10 is connected to an external hydraulic station. A mounting frame 16 is fixedly connected to the output end of the hydraulic cylinder 10. A second motor 13 is fixedly connected to the side wall of the mounting frame 16. A reciprocating screw 15 is fixedly connected to the output shaft of the second motor 13. A limiting plate 14 is provided on the reciprocating screw 15. The spiral groove on the surface of the reciprocating screw 15 cooperates with the nut inside the limiting plate 14. When the screw rotates, the limiting plate 14 cannot rotate with the screw due to the constraint of the two limiting strips 8 on both sides. It can only move axially. The inner walls of the two vertical parts of the limiting plate 14 are provided with anti-slip textures or anti-slip pads, which can drive the collection frame 6 to sway left and right, so that the products falling into the collection frame 6 are dispersed in the collection frame 6, without the need to manually push the products piled up in the collection frame 6.

[0028] In this utility model, a vertical plate 11 is fixedly connected to the top of the mounting frame 7, and two cylinders 20 are fixedly connected to the side wall of the vertical plate 11. A push plate 21 is fixedly connected to the output end of the cylinders 20. The two cylinders 20 can move synchronously and push the collection frame 6 that needs to be removed out of the placement tray 5 without the need for manual pulling of the collection frame 6, thus reducing the labor intensity of workers.

[0029] In this utility model, a plurality of support rods 17 are fixedly connected to the lower end of the placement tray 5. The plurality of support rods 17 are arranged at equal intervals. The lower end of the support rods 17 is provided with balls 18, which can not only bear the weight of the plurality of collection frames 6, but also convert the frictional resistance when the placement tray 5 rotates into the rolling friction of the balls 18, making the placement tray 5 rotate more smoothly, reducing the load on the first motor 12, and extending the service life of the equipment.

[0030] In this utility model, the mounting base plate 3 has connecting plates 2 on both sides. The connecting plates 2 are fixedly connected to the main body 1 of the packaging machine. The side wall of the connecting plate 2 has multiple bolts, which facilitates accurate positioning during equipment installation and provides convenience for later maintenance (such as replacing the rotating shaft and inspecting the placement tray 5). It can be quickly disassembled without affecting the operation of the main body 1 of the packaging machine.

[0031] When in use, after the collection box 6 is filled with packaged pastries, the controller 19 starts the first motor 12. Its output shaft drives the second gear on the rotating shaft 4 to rotate through the first gear, causing the placement tray 5 to rotate at a specific angle (such as 90°). The next empty collection box 6 is rotated to the bottom of the discharge port of the packaging machine body 1. The limit bar 8 and the stop bar 9 always constrain the position of the collection box 6 during the rotation to ensure accurate receiving position. When the collection box 6 filled with products rotates to the right side of the placement tray 5, the stop bar 9 can be pulled out and the collection box 6 can be removed.

[0032] When the collection box 6 receives the material, the hydraulic cylinder 10 extends to lower the limiting plate 14 above the collection box 6. The second motor 13 drives the reciprocating screw 15 to rotate forward and backward, causing the limiting plate 14 to move left and right. The limiting plate 14 contacts the side wall of the collection box 6 through the anti-slip texture, pushing the collection box 6 to shake synchronously, so that the accumulated pastries are evenly dispersed under the action of inertia, without the need for manual intervention.

[0033] When the collection box 6 is full and the product is dispersed and rotated to the right side of the placement tray 5, the piston rod of the cylinder 20 extends and pushes the push plate 21 to push the collection box 6 out of the edge of the placement tray 5. At the same time, the placement tray 5 rotates to replenish the new empty collection box 6, realizing the automated cycle of "receiving-dispersing-discharging".

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
