Description

Technical Field

[0001] This utility model relates to the field of side-sealing packaging machine technology, specifically to an automatic feeding structure for a side-sealing packaging machine. Background Technology

[0002] The automatic feeding structure of a side-sealing packaging machine is a device that automatically, orderly, and accurately transports products to be packaged from their initial storage position to the packaging station through the coordinated operation of mechanical transmission, pneumatic control, sensor detection, and intelligent control system. It is widely used in the side-sealing packaging process of industries such as food, pharmaceuticals, and daily necessities. However, it has drawbacks: the feeding step requires manual operation, leading to low packaging efficiency, and the feeding mechanism has poor compatibility, requiring customized equipment for different products. To address these shortcomings, existing technology (Chinese patent application number: 202123378339.X, authorized announcement date: 2022-07-12) discloses... This fully automatic four-side sealing packaging machine features a multi-material compatible feeding mechanism, including a worktable, a conveying assembly, a storage assembly, and a gripping assembly. The storage assembly comprises several storage bins for holding different types of materials, and the gripping assembly includes several gripping components for gripping different types of materials. Each storage bin corresponds one-to-one with a specific gripping component. By setting up these one-to-one corresponding storage bins and gripping components, different types of materials can be placed in different storage bins, and the corresponding gripping components can be used to grip the materials onto the conveying assembly. This solves the problems of poor compatibility of traditional packaging machine feeding mechanisms and low packaging efficiency caused by manual feeding.

[0003] Existing technology involves gripping materials with a gripping component and placing them on a conveying component, which then transports the materials. However, when products are freely conveyed by belt or gravity, uneven spacing can easily occur due to speed differences, material accumulation, or inertial collisions (e.g., products in the front row stop while those in the back row are squeezed and stacked). This fails to meet the "uniform spacing" requirement of the side sealing process. At the same time, products may deviate from the center line due to conveyor line vibration, belt misalignment, or inertia, or even slip off the sides of the conveyor line. Therefore, we have proposed an automatic feeding structure for the side sealing packaging machine that can effectively solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic feeding structure for a side-sealing packaging machine to solve the problems mentioned in the background art, such as uneven spacing caused by speed differences, material accumulation, or inertial collisions when products are freely conveyed by belts or gravity (e.g., products in the front row stop and products in the back row are squeezed and stacked), which cannot meet the "uniform spacing" requirement of the side-sealing process. At the same time, products may deviate from the center line due to conveyor line vibration, belt deviation, or inertia, or even slip off the sides of the conveyor line.

[0005] To achieve the above object, the utility model provides the following technical solutions: An automatic feeding structure of a side-sealing packaging machine, including a machine body. A belt conveyor line is installed on the right side of the upper surface of the machine body, and a side-sealing mechanism and a cross-sealing mechanism are respectively installed on the left side of the upper surface of the machine body. It further includes: A motor is bolted and installed above the back of the machine body, and a cylinder is bolted and fixed above the right side of the machine body. Guide plates are symmetrically arranged on the upper surface of the machine body with respect to the center point of the belt conveyor line. A pushing block is fixedly connected to the upper surface of the belt conveyor line. Fixing plates are bolted at equal intervals on the opposite surfaces of the two guide plates. Rotating rods are connected at equal intervals on the front and rear sides of the upper surface of the machine body, and the rotating rods and the fixing plates are respectively connected through movable plates and connecting plates. A driving gear is sleeved and fixed on the outer side of the lower end of the rotating rod. A driving plate is slidably connected inside the machine body.

[0006] Preferably, the belt conveyor line is rotationally connected to the upper surface of the machine body through a shaft, and the shaft end of the belt conveyor line is fixedly connected to the output end of the motor.

[0007] Preferably, multiple pushing blocks are evenly distributed on the upper surface of the belt conveyor line, and the use of multiple pushing blocks can achieve equidistant material distribution of products.

[0008] Preferably, the two guide plates are slidably arranged on the upper surface of the machine body. Tooth blocks are fixedly arranged at equal intervals on the front and rear sides of the inner wall of the driving plate.

[0009] Preferably, the fixing plate is arranged in an inverted "L" shape. The rotating rod is rotationally connected to the upper surface of the machine body. Both ends of the movable plate are respectively hinged to the inner side surface of the fixing plate and one end of the connecting plate.

[0010] Preferably, both ends of the connecting plate are respectively hinged to the top of the rotating rod and the other end of the movable plate.

[0011] Preferably, the right side of the driving plate is fixedly connected to the output end of the cylinder. The driving plate is arranged in a "C" shape, and multiple tooth blocks on the inner side surface of the driving plate are meshed with the driving gear.

[0012] Compared with the prior art, the beneficial effects of the utility model are: The automatic feeding structure of this side-sealing packaging machine adopts a new structural design, and the specific content is as follows:

[0013] (1) The product is first moved on the belt conveyor line and then flows into the finger-pushing conveying structure. The belt conveyor line can achieve long-distance and continuous transmission of the product, and convey the product from the initial position to a designated position close to the side-sealing packaging machine.

[0014] (2) During the finger-push conveying process, the products are divided at equal intervals to maintain a uniform spacing between them. At the same time, they flow into the side sealing mechanism along with the packaging film for side sealing. The finger-push structure can precisely control the product spacing, which facilitates the orderly progress of the subsequent packaging process and ensures that the relative position of the product and the packaging film is accurate during side sealing. After the side sealing is completed, the product is then conveyed to the horizontal sealing mechanism for horizontal sealing to complete the entire packaging process. The horizontal sealing operation seals both ends of the product, forming a complete and independent packaging unit.

[0015] (3) The guide plates set on both sides of the belt conveyor can guide the product to move smoothly along a fixed trajectory, avoiding jamming or misalignment of packaging due to deviation, skewing or scattering during the conveying process.

[0016] (4) The drive plate is moved by the cylinder, so that the drive plate drives the active gear to rotate by multiple tooth blocks, which in turn drives the rotating rod to rotate the movable plate. At the same time, the movable plate drives the connecting plate to rotate and pulls the guide plate to move. At this time, the guide plates on both sides move relative to each other or in opposite directions, so that the distance between the two guide plates can be adjusted. It can quickly switch the conveying of products of different widths and shapes without replacing the entire set of conveying components, shortening the changeover time and improving the versatility of the equipment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: an automatic feeding structure for a side-sealing packaging machine;

[0026] Example 1: To address the problem that in existing technologies, when products are freely conveyed by belts or gravity, uneven spacing (e.g., products in the front row stop while those in the back row are pushed together) can easily occur due to speed differences, material accumulation, or inertial collisions, failing to meet the "uniform spacing" requirement of the side sealing process, and the possibility that products may deviate from the centerline or even slip off the sides of the conveyor line due to conveyor line vibration, belt misalignment, or inertia, the following solution is disclosed. Please refer to the following for details. Figures 1-3 and Figure 5 As shown, the device includes a machine body 1, a belt conveyor 2 mounted on the right side of the upper surface of the machine body 1, and a side sealing mechanism 3 and a horizontal sealing mechanism 4 mounted on the left side of the upper surface of the machine body 1. It also includes a motor bolted to the upper back of the machine body 1, the belt conveyor 2 rotatably connected to the upper surface of the machine body 1 via a shaft, the shaft end of the belt conveyor 2 fixedly connected to the output end of the motor, a cylinder bolted to the upper right side of the machine body 1, and push blocks 6 fixedly connected to the upper surface of the belt conveyor 2. Multiple push blocks 6 are evenly distributed on the upper surface of the belt conveyor 2, and the multiple push blocks 6 enable equidistant material distribution of the products.

[0027] The belt conveyor 2 is driven by a motor to rotate, and the product is placed on the belt conveyor 2. At the same time, the belt conveyor 2 moves and then flows into the finger push conveyor structure. The belt conveyor 2 can realize long-distance and continuous transmission of products, transporting the products from the initial position to the designated position near the side sealing packaging machine. During the finger push conveying process, the push blocks 6 set at equal intervals on the belt conveyor 2 can divide the products at equal intervals, so that the products maintain a uniform spacing. At the same time, they flow into the side sealing mechanism 3 together with the packaging film for the side sealing operation. The finger push structure can precisely control the product spacing, which facilitates the orderly progress of the subsequent packaging process and ensures the accurate relative position of the product and the packaging film during the side sealing. After the side sealing is completed, the product is then transported to the horizontal sealing mechanism 4 for the horizontal sealing operation, completing the entire packaging process. The horizontal sealing operation seals both ends of the product, forming a complete and independent packaging unit.

[0028] Example 2: Unlike Example 1, this example utilizes two guide plates 5 to prevent product deviation during transport. See details... Figures 1-4As shown in the figure, guide plates 5 are symmetrically arranged on the upper surface of the machine body 1 with respect to the center point of the belt conveyor line 2.

[0029] Through the guide plates 5 arranged on both sides of the belt conveyor line 2, products can be guided to move smoothly along a fixed track, avoiding material jamming or packaging misalignment caused by offset, skew or scattering during the conveying process.

[0030] Embodiment 3: Different from Embodiment 2, in this embodiment, the distance between the two guide plates 5 can be adjusted, and the conveying of products with different widths and shapes can be quickly switched. For specific reference, see Figures 1-4 and Figure 6 As shown in the figure, fixing plates 9 are bolted at equal intervals on the opposite surfaces of the two guide plates 5. Rotating rods 7 are connected at equal intervals on the front and rear sides of the upper surface of the machine body 1, and the rotating rods 7 and the fixing plates 9 are respectively connected through movable plates 8 and connecting plates 10. A driving gear 12 is sleeved and fixed on the outer side of the lower end of the rotating rod 7. A driving plate 11 is slidably connected inside the machine body 1. Tooth blocks are fixed at equal intervals on the front and rear sides of the inner wall of the driving plate 11. The fixing plate 9 is arranged in an inverted "L" shape. The rotating rod 7 is rotatably connected to the upper surface of the machine body 1. Both ends of the movable plate 8 are hinged between the inner side surface of the fixing plate 9 and one end of the connecting plate 10 respectively. Both ends of the connecting plate 10 are hinged between the top of the rotating rod 7 and the other end of the movable plate 8 respectively. The right side of the driving plate 11 is fixedly connected to the output end of the air cylinder. The driving plate 11 is arranged in a "C" shape, and a plurality of tooth blocks on the inner side surface of the driving plate 11 are meshed with the driving gear 12.

[0031] By pushing the driving plate 11 to move through the air cylinder, the driving plate 11 uses a plurality of tooth blocks to drive the driving gear 12 to rotate, and then the rotating rod 7 drives the movable plate 8 to rotate. At the same time, the movable plate 8 drives the connecting plate 10 to rotate and pulls the guide plate 5 to move. At this time, the two guide plates 5 move relatively or in opposite directions, so that the distance between the two guide plates 5 can be adjusted, and the conveying of products with different widths and shapes can be quickly switched. There is no need to replace the whole set of conveying components, which shortens the changeover time and improves the versatility of the equipment.

[0032] The content not described in detail in this specification belongs to the prior art well known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
