Description

Technical Field

[0001] This utility model belongs to the field of slaughtering equipment technology, and in particular relates to an automatic bagging equipment for frozen products. Background Technology

[0002] As is well known, frozen pork products are packaged using a fixed weight system. The products are pre-weighed in iron pans and placed in a pre-cooling warehouse to cool. Once the pre-cooling temperature is reached, workers pull the frozen pork products out of the cold storage and stack them on the workbench in the packaging room. The frozen products are then manually tapped off the iron pans on the workbench, and woven bags are then placed over them. Finally, the bags are sewn and labeled.

[0003] It is evident that the current frozen product bagging process is repetitive manual labor, relying on manual labor to pack frozen products into packaging bags, and it cannot be automated by connecting with upstream and downstream processes. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides an automatic bagging device for frozen products, which solves the above problems.

[0005] To achieve the above objectives, this utility model provides an automatic bagging device for frozen products, comprising:

[0006] A bag-transfer mechanism, used to transport packaging bags to an opening platform;

[0007] The bag opening mechanism includes a pinch gripper and a pinch gripper opening and closing mechanism. The pinch gripper opening and closing mechanism drives the pinch gripper to pinch open and clamp the bag opening on the bag opening platform, and pulls the bag opening up and down.

[0008] A conveying mechanism for conveying items through the bag opening into a packaging bag.

[0009] Compared with the prior art, this application has the following advantages: In use, firstly, the bag-moving mechanism moves the packaging bag to the bag-opening platform, then the pinch-opening mechanism drives the pinch-opening mechanism to pinch and rub open the bag opening, and pulls the bag opening up and down, so that the items can easily enter the packaging bag through the bag opening; finally, the conveying mechanism drives the items into the packaging bag, thereby completing the automatic bagging of frozen products.

[0010] Therefore, this application solves the problem of bag mouth adhesion by designing a pinch gripping and pinch gripping opening and closing mechanism, so that the bag mouth can be opened smoothly. By using automated bagging equipment to replace manual labor, it not only reduces the labor intensity of workers, but also realizes the connection with upstream and downstream through the conveying mechanism, thereby achieving automated production.

[0011] Furthermore, the pinch-opening mechanism includes a lifting device, an upper pneumatic finger, and a lower pneumatic finger. The upper and lower pneumatic fingers are respectively provided on the upper and lower parts of the bag opening platform. The upper and lower pneumatic fingers are respectively connected to the pinch gripper, and the lifting device is connected to the upper pneumatic finger. When the upper and lower pneumatic fingers are working, they respectively drive the pinch gripper to first rub open the bag opening and then pull the bag opening up and down.

[0012] Furthermore, the pinching heights on both sides of the same upper or lower pneumatic finger are uneven.

[0013] Furthermore, the bag transfer mechanism includes a front-to-back moving device and a negative pressure adsorption device connected to the front-to-back moving device. The negative pressure adsorption device is used to adsorb the packaging bags on the bag supply platform, so that when the front-to-back moving device is working, it drives the negative pressure adsorption device to move toward the bag opening platform, thereby conveying the packaging bags to the bag opening platform.

[0014] Furthermore, the negative pressure adsorption device includes a suction cup frame lifting assembly, a suction cup frame, and a suction cup connected to the suction cup frame. One end of the suction cup frame lifting assembly is connected to the front and rear moving device, and the other end is connected to the suction cup frame.

[0015] Furthermore, there are four suction cups, and the spacing between the four suction cups matches the size of the packaging bag, thereby ensuring that the suction cups can stably lift the packaging bag from four parts of the packaging bag.

[0016] Furthermore, it also includes a pusher mechanism for pushing the items on the conveying mechanism into the packaging bag.

[0017] Furthermore, it also includes a bag-handling mechanism for pushing the packaging bags on the opening platform to their central position.

[0018] Furthermore, a non-powered roller is provided between the conveying mechanism and the bag opening platform.

[0019] Furthermore, the unpowered roller is also equipped with a bag-opening mechanism for opening the bag opening.

[0020] Furthermore, the bag supply platform includes at least one bag supply box and a bag supply drive device for driving the bag supply box to rotate. The bag supply drive device is a motor cam turntable structure, and the bag supply box is connected to the motor cam turntable structure. Attached Figure Description

[0031] 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.

[0032] like Figures 1-3As shown, this utility model discloses an automatic bagging device for frozen products, comprising:

[0033] Bag transfer mechanism 1, which is used to transport the packaging bag to the bag opening platform 2;

[0034] The bag opening mechanism 3 includes a pinch gripper 31 and a pinch gripper opening and closing mechanism 32. The pinch gripper opening and closing mechanism 32 drives the pinch gripper 31 to pinch open and clamp the bag opening on the bag opening platform 2, and pulls the bag opening up and down.

[0035] Conveying mechanism 4 is used to transport items through the bag opening into the packaging bag.

[0036] Compared with the prior art, this application has the following advantages: When in use, the bag transfer mechanism 1 first moves the packaging bag to the bag opening platform 2, then the pinching and opening mechanism 32 drives the pinching and clamping mechanism 31 to open and tighten the bag opening, and pulls the bag opening up and down, so that the items can easily enter the packaging bag through the bag opening; finally, the conveying mechanism 4 drives the items into the packaging bag, thereby completing the automatic bagging of frozen products.

[0037] Therefore, this application solves the problem of bag mouth adhesion by designing the pinch gripper 31 and the pinch gripper opening and closing mechanism 32, so that the bag mouth can be opened smoothly. By using automated bagging equipment to replace manual labor, it not only reduces the labor intensity of workers, but also realizes the connection with upstream and downstream through the conveying mechanism 4, thereby realizing automated production.

[0038] Following the above embodiment, more specifically, the pinching opening and closing mechanism 32 includes a lifting device 321, an upper pneumatic finger 322, and a lower pneumatic finger 323. The upper and lower parts of the bag opening platform 2 are respectively provided with the upper pneumatic finger 322 and the lower pneumatic finger 323. The upper pneumatic finger 322 and the lower pneumatic finger 323 are respectively connected to the pinching gripper 31, and the lifting device 321 is connected to the upper pneumatic finger 322, so that when the upper pneumatic finger 322 and the lower pneumatic finger 323 work, they respectively drive the pinching gripper 31 to first rub open the bag opening, and then pull the bag opening of the packaging bag up and down.

[0039] In this process, after the packaging bag is placed on the opening platform 2, the lower pneumatic finger 323 drives the pinch gripper 31 to pinch and open the lower part of the packaging bag opening. The lifting device 321 drives the upper pneumatic finger 322 to contact the upper part of the packaging bag opening. The upper pneumatic finger 322 drives the pinch gripper 31 to pinch and open the upper part of the packaging bag opening. Then the lifting device 321 moves upward, driving the upper pneumatic finger 322 upward, thereby pulling the packaging bag opening up and down.

[0040] The upper pneumatic finger 322 and the lower pneumatic finger 323 have the same structure and are both existing technologies, so they will not be described in detail. Taking the upper pneumatic finger 322 as an example, Figure 6 and Figure 7As shown, the pinch grips 31 on the left and right sides are of different heights. Their design, which mimics human fingers, can pry open and then tighten the sticky packaging bag opening, effectively solving the problem that the packaging bag opening cannot be opened due to sticking.

[0041] Following the above embodiment, more specifically, the bag transfer mechanism 1 includes a front and rear moving device 11 and a negative pressure adsorption device 12 connected to the front and rear moving device 11. The negative pressure adsorption device 12 is used to adsorb the packaging bags on the bag supply platform 8, so that when the front and rear moving device 11 is working, it drives the negative pressure adsorption device 12 to move toward the bag opening platform 2, thereby conveying the packaging bags to the bag opening platform 2.

[0042] Furthermore, the negative pressure adsorption device 12 includes a suction cup frame lifting assembly 121, a suction cup frame 122, and a suction cup 123 connected to the suction cup frame 122. One end of the suction cup frame lifting assembly 121 is connected to the front and back moving device 11, and the other end is connected to the suction cup frame 122.

[0043] like Figure 3 As shown, the structure of the front and rear moving device 11 can be a motor belt drive or a cylinder drive. This application adopts the cylinder drive. Therefore, when the front and rear moving device 11 is working, it can drive the suction cup frame lifting assembly 121 to move back and forth. The suction cup frame lifting assembly 121 can be a cylinder drive, which can drive the suction cup frame 122 to move up and down, and then drive the suction cup 123 to move up and down.

[0044] During operation, the suction cup lifting assembly 121 drives the suction cup 123 downward through the suction cup frame 122, so that the suction cup 123 comes into contact with the packaging bag on the bag supply platform 8. After the suction cup 123 is ventilated, the packaging bag is lifted by the negative pressure. Then, the suction cup lifting assembly 121 drives the suction cup 123 upward through the suction cup frame 12, so that the packaging bag is separated from the packaging bag below it (or this action can be omitted, or the back-and-forth moving device 11 can move the packaging bag back and forth, thereby separating it from the packaging bag below it). Next, the back-and-forth moving device 11 drives the packaging bag to the top of the bag opening platform 2. The suction cup lifting assembly 121 drives the suction cup 123 downward through the suction cup frame 12, so that the packaging bag comes into contact with the bag opening platform 2 below it. The suction cup 123 is de-ventilated, and the packaging bag falls onto the bag opening platform 2.

[0045] Following the above embodiment, a more preferable embodiment is that there are four suction cups 123, and the spacing between the four suction cups 123 matches the size of the packaging bag, thereby ensuring that the suction cups 123 can stably lift the packaging bag from four parts of the packaging bag. It should be noted that the four suction cups 123 simultaneously and evenly suction the four parts of the packaging bag, which not only improves the stability and reliability of lifting the packaging bag, but also does not affect the placement of adjacent packaging bags below, which is more conducive to the reliable operation of the next process.

[0046] Following the above embodiments, a more preferred embodiment is, as follows: Figure 4 As shown, it also includes a pushing mechanism 5 for pushing items on the conveying mechanism 4 into the packaging bag. The pushing mechanism 5 includes a motor belt drive structure, a cylinder lifting structure, and a push plate connected to the cylinder lifting structure. The motor belt drive structure drives the cylinder lifting structure to move left and right, thereby driving the push plate to move left and right. The cylinder lifting structure drives the push plate to move up and down, thus realizing the up-down and left-right movement of the push plate, ultimately pushing the items on the conveying mechanism 4 into the packaging bag.

[0047] Following the above embodiments, a more preferred embodiment is, as follows: Figure 2 As shown, it also includes a bag-sorting mechanism 6 for pushing the packaging bags on the bag-opening platform 2 to their central position. The bag-sorting mechanism 6 includes a cylinder drive structure and a baffle. The cylinder drive structure drives the baffle to move back and forth, thereby pushing the packaging bags to the central position of the bag-opening platform 2 to facilitate the next process.

[0048] Following the above embodiments, a more preferable embodiment is that a non-powered roller 7 is provided between the conveying mechanism 4 and the bag opening platform 2. Because existing technologies often use powered rollers, multiple rollers rotate independently, potentially causing the inner film of the item to be torn and damaged by adjacent rollers. Therefore, this application uses a non-powered roller 7, which only rotates when subjected to force, thus preventing the problem of damage to the inner film of the item due to tearing between rollers.

[0049] Following the above embodiments, a more preferred embodiment is, as follows: Figure 5 As shown, the non-powered roller 7 is also equipped with a bag-opening mechanism 9 for opening the bag opening. The bag-opening mechanism 9 includes a cylinder drive structure and a support plate. The cylinder drive structure is used to drive the support plate to open or close. When the bag opening is opened vertically under the action of the gripper 31, the cylinder drive structure drives the support plate to open again, thereby opening the bag opening horizontally. This not only facilitates the entry of the item into the bag, but also minimizes the contact between the inner film of the item and the rough inner wall of the bag, preventing the inner film of the item from being scratched.

[0050] Following the above embodiments, more preferably, the bag supply platform 8 includes at least one bag supply box and a bag supply drive device for driving the bag supply box to rotate. The bag supply drive device is a motor cam turntable structure, and the bag supply box is connected to the motor cam turntable structure. There can be four bag supply boxes, each holding four different sizes of packaging bags. According to actual production needs, the rotation of the bag supply boxes is achieved through the motor cam turntable structure, allowing selection of one size of packaging bag to meet the needs of different packaging bag sizes.

[0051] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
