Description

Technical Field

[0001] This utility model relates to the field of packaging material feeding technology, and in particular to an automatic cleaning container-type inner packaging material feeding mechanism. Background Technology

[0002] In the food and pharmaceutical industries, such as those producing jelly and yogurt, some products use plastic cups, boxes, or bowls as inner packaging materials, such as yogurt cups and jelly cups. These are transported sequentially to the filling machine via conveyor lines. Although the inner packaging containers provided by upstream suppliers or the blow molding / forming process are clean, these inner packaging materials may still become contaminated with light impurities such as paper scraps, plastic fragments, dust, and insects during storage, transportation, or loading, affecting the safety of food or pharmaceuticals. Currently, this is addressed through manual sampling inspection. However, manual sampling carries a high risk of missing items; once a container with foreign matter that slips through the inspection is filled and sealed, it becomes a fatal product quality defect.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-4 As shown, this utility model provides an automatic cleaning container-type inner packaging material feeding mechanism, including a conveying unit 1, a feeding unit 2 and a cleaning unit 3, wherein the feeding unit 2 and the cleaning unit 3 are sequentially arranged on the conveying unit 1.

[0024] Conveying unit 1 uses a chain conveyor belt, with multiple rows of storage holes 12 on the chain plates 11, into which the inner packaging material 4 can be placed. The inner packaging material 4 has a tapered structure that is wider at the top and narrower at the bottom, with raised rings on the edges; correspondingly, support grooves are formed on the inner edges of the storage holes 12, located directly below the raised rings to achieve the support and positioning of the inner packaging material 4. Conveying unit 1 is driven by a stepper motor to achieve step-by-step conveying of the inner packaging material 4. The control of loading unit 2 and cleaning unit 3 is interlocked with the main control system of the production line to achieve synchronous start and stop.

[0025] The feeding unit 2 is used to accurately feed the inner packaging material 4 to be cleaned into the conveying unit 1. It consists of a feeding rack on the upper side of the chain plate 11 and a support frame on the lower side of the chain plate 11. The feeding rack includes a frame body 21, and multiple storage racks 211 are provided on the frame body 21 corresponding to the storage holes 12. The inner packaging material 4 to be cleaned is stacked and placed in the storage racks 211. The storage racks 211 are composed of multiple vertically arranged limiting rods, which are used to limit the horizontal position of the inner packaging material 4 and prevent it from shifting.

[0026] A separating mechanism 22 is mounted on the lower side of the storage rack 211. A first cylinder 24 is installed on one side of the separating mechanism 22. The piston rod of the first cylinder 24 pushes and pulls the separating mechanism 22 left and right, causing the stacked inner packaging materials 4 to fall onto the support frame one by one. Two sets of guide wheels 212 are provided on each of the left and right sides of the storage rack 211. The separating mechanism 22 is clamped between the guide wheels 212, providing guidance for the left and right sliding of the separating mechanism 22 and reducing the frictional resistance during the sliding process. The separating mechanism 22 is generally square in shape. Horizontal support blocks 221 and separating blocks 222 with guide slopes are staggered on the front and rear sides of its inner frame, corresponding to the positions of each storage hole 12. Both the support blocks 221 and the separating blocks 222 can be supported under the convex ring of the inner packaging material 4. There is a height difference between the upper surface of the support block 221 and the bottom surface of the separating block 222, which matches the height of the convex ring, and a notch 223 is provided between them. The first cylinder 24 quickly pushes the separation mechanism 22, causing the separation block 222 to be inserted into the gap between the bottommost and second-bottom inner packaging material 4, and the bottommost inner packaging material 4 falls from the notch 223.

[0027] The working process of the separation mechanism 22 is as follows: When the separation mechanism 22 is in the first position, the bearing block 221 is supported on the protruding ring at the edge of the bottom inner packaging material 4; the piston rod of the first cylinder 24 quickly pushes the separation mechanism 22 to the second position, the separation block 222 is inserted into the gap between the bottom and the second bottom inner packaging material 4, so that the two are separated, and the bottom inner packaging material 4 loses support and falls from the notch 223 onto the support frame; after the cylinder piston rod is retracted, the separation mechanism 22 returns to the first position, and the original second bottom inner packaging material 4 falls onto the bearing block 221, completing a single feeding action.

[0028] The support frame includes a mounting plate 25, a lifting frame 26, and a second cylinder 27. The mounting plate 25 is fixedly assembled inside the conveying unit 1. The lifting frame 26 is located above the mounting plate 25, and its top has multiple support rods 261 corresponding to the storage hole 12, used to support the inner packaging material 4 and allow the inner packaging material 4 to fall into the storage hole 12. The bottom of the mounting plate 25 is equipped with the second cylinder 27, and the piston rod of the second cylinder 27 is connected to the bottom of the lifting frame 26 to drive the lifting frame 26 to rise and fall. Guide bushings 251 are provided on both sides of the bottom of the mounting plate 25, and guide posts 262 are provided on the bottom of the lifting frame 26. The guide bushings 251 and the guide posts 262 cooperate to provide guidance for the rising and falling movement of the lifting frame 26. The support rods 261 support the bottom of the lowest inner packaging material 4, realizing the slow lowering of the inner packaging material 4 into the storage hole 12, ensuring positioning accuracy, and allowing the inner packaging material 4 to fall accurately into the storage hole 12.

[0029] The loading process is as follows: the staff stacks the inner packaging material 4 to be cleaned into the storage rack 211, and the drive unit drives the chain plate 11 to move step by step under the drive of the stepper motor; when the storage hole 12 moves directly below the loading unit 2, the second cylinder 27 drives the lifting frame 26 to rise, and the first cylinder 24 pushes the separation mechanism 22 to make the bottom inner packaging material 4 fall onto the support rod 261; then the piston rod of the second cylinder 27 retracts, and the lifting frame 26 drives the inner packaging material 4 to slowly descend, so that the inner packaging material 4 falls accurately into the storage hole 12; after the loading is completed, the chain plate 11 carries the inner packaging material 4 and continues to convey it forward.

[0030] The cleaning unit 3 is located behind the feeding unit 2 and is used to remove impurities from the inner packaging material 4. It includes a base plate 31 fixedly mounted on the conveying unit 1 and a detachable suction head 32 mounted on the base plate 31. The two work together to form a negative pressure chamber. The base plate 31 is attached to the surface of the chain plate 11 and has a through hole 311 at the position corresponding to the storage hole 12. A baffle 312 is provided in the through hole 311, and an air blowing head 313 is installed in the baffle 312. The baffle 312 limits the inner packaging material 4 and can prevent the inner packaging material 4 from being sucked up by the negative pressure. The air blowing head 313 is connected to an air pump through a pipeline and uses an intermittent blowing method to blow airflow into the inner packaging material 4, blowing up light impurities such as paper scraps, plastic fragments, dust, and insects. The suction head 32 is connected to the vacuum tube 321, which is connected to the negative pressure generating unit. The negative pressure generating unit can be a centrifugal fan, a negative pressure generator, etc. The negative pressure generating unit is kept in the normally open state to generate a strong negative pressure airflow and continuously extract impurities in the negative pressure chamber. The negative pressure generating unit has a built-in filter screen, and the extracted air is filtered before being discharged. Foreign objects are collected in a unified manner, which facilitates the analysis of the source of foreign objects and the traceability of production process quality.

[0031] The base plate 31 and the suction head 32 are connected by a spring clip 33. The base plate 31 and the suction head 32 can be disassembled by releasing the spring clip 33, which facilitates cleaning and maintenance of the interior of the cleaning unit 3. An inclined guide plate 314 is provided on the front side of the base plate 31. The height of the guide plate 314 gradually decreases along the direction close to the cleaning unit 3. If the inner packaging material 4 does not fall completely into the storage hole 12, the guide plate 314 can correct the posture of the inner packaging material 4 during the conveying process of the chain plate 11, pressing it into the storage hole 12 to ensure the subsequent cleaning effect.

[0032] The cleaning process is as follows: the chain plate 11 carrying the inner packaging material 4 to be cleaned moves to the inside of the cleaning unit 3 and then stops. The air blowing head 313 blows high-pressure air into the inner packaging material 4 from top to bottom, blowing up the light impurities inside. At the same time, the negative pressure airflow generated by the negative pressure generating unit extracts the blown impurities through the vacuum tube 321, completing the impurity removal. After the cleaning is completed, the chain plate 11 drives the cleaned inner packaging material 4 to continue to be conveyed to the downstream filling machine for filling operation.

[0033] The overall operating procedure of the device is as follows: the staff stacks the inner packaging material 4 to be cleaned into the storage rack 211. The first cylinder 24 separates the inner packaging material 4 one by one through the push-pull separation mechanism 22, so that the inner packaging material 4 falls onto the support rod 261 of the support frame. The second cylinder 27 drives the lifting frame 26 to descend, accurately sending the inner packaging material 4 into the storage hole 12. The inner packaging material 4 is conveyed to the cleaning unit 3 by the chain plate 11. Impurities are removed by the combined action of high-pressure blowing and negative pressure adsorption by the air blowing head 313. The cleaned inner packaging material 4 is conveyed to the downstream equipment to complete the subsequent processes.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
