Abstract
Description
Technical Field
[0001] The utility model belongs to the field of feed packaging, in particular to a feed quantitative packaging machine. Background Art
[0002] Feed is a general term for food for animals raised by humans. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed includes more than ten types of feed raw materials, such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oil, meat and bone meal, grains, feed additives, etc. After the feed is prepared, it needs to be stored.
[0003] At present, most breeding farms use silos to store bulk feed raw materials. Breeding farms that do not use silos can only store them in warehouses in the form of traditional small packages. Packaging feed in small packages can prevent feed accumulation and moldy raw materials. In addition, filling and packaging feed in small packages also facilitates the transportation of feed and subsequent feeding.
[0004] Most of the feed used in breeding is in the form of granules or powders. When the feed in the sub-bag reaches the required weight, the discharge bin is usually closed to stop the feed from falling into the sub-bag. During the closing of the discharge bin, some of the feed in the discharge bin will continue to fall into the sub-bag, resulting in a large weight error between the feed in each sub-bag and the required feed, making it impossible to truly achieve quantitative packaging of the feed. Utility Model Content
[0005] In view of the above problems, the purpose of the present invention is to provide a feed quantitative packaging machine, aiming to solve the problem of large error in the feed in each sub-bag when the existing feed quantitative packaging machine is packaging the feed.
[0006] The utility model adopts the following technical solutions:
[0007] The feed quantitative packaging machine includes a frame, on which a supporting frame and a weighing frame are respectively provided, the weighing frame is located inside the supporting frame, a lower hopper is provided on the weighing frame, a bag clamping mechanism is provided below the lower hopper, a feeding mechanism is provided on the supporting frame, the feeding mechanism includes a feed bin and a discharge bin, the outlet of the discharge bin is arranged toward the top opening of the lower hopper, the feed bin and the discharge bin are connected through a pair of spiral casings, a spiral shaft is rotatably provided inside the spiral casing, the spiral shaft is provided with spiral blades, a driving motor for driving the spiral shaft to rotate is also provided on the supporting frame, and a sealing mechanism is provided on the side wall of the discharge bin toward the outlet of each spiral casing.
[0008] Furthermore, the sealing mechanism includes a sealing cylinder and a pair of sliding sleeves installed on the discharge bin, the driving shaft of the sealing cylinder is provided with a sealing pressure plate matching the outlet of the spiral casing, and a sliding rod is inserted into each sliding sleeve, and the sliding rod is connected to the sealing pressure plate.
[0009] Furthermore, weighing modules are provided at the four corners of the frame, and the weighing frame is provided on the weighing modules. Eyebolts are provided at the four corners of the bottom of the weighing frame, and each eyebolt is provided with a wide-mouth hook.
[0010] Furthermore, the bag clamping mechanism includes a fixed plate installed on the lower hopper, the fixed plate is rotatably provided with two pairs of jaws downward, a linkage rod is provided between the same pair of jaws, a clamping block is provided at the bottom of each jaw, a clamping plate is provided between the same pair of clamping blocks, and a bag clamping cylinder is rotatably provided on one pair of jaws, and the driving shaft of the bag clamping cylinder is rotatably connected to the other jaw on the same side.
[0011] Furthermore, the side wall of the lower hopper is provided with an air hammer.
[0012] The beneficial effect of the utility model is that since the packing bag is installed on the weighing frame through the wide-mouth hook, when the feed is packed into the packing bag, when the feed in the packing bag reaches the required weight, the driving motor stops working immediately, the spiral blade stops conveying the feed, and the feed no longer falls into the discharge bin. Then the sealing mechanism closes the outlet of the spiral casing, further preventing the feed from falling into the discharge bin, thereby achieving the purpose of quantitative packaging of the feed.

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0017] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.
[0018] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.
[0019] Combination Figure 1-3 As shown, the feed quantitative packaging machine includes a frame 1, on which a support frame 2 and a weighing frame 3 are respectively provided, the weighing frame 3 is located in the support frame 2, a lower hopper 4 is provided on the weighing frame 3, a bag clamping mechanism is provided below the lower hopper 4, a feeding mechanism is provided on the support frame 2, the feeding mechanism includes a feed bin 5 and a discharge bin 6, the outlet of the discharge bin 6 is arranged toward the top of the lower hopper 4, the feed bin 5 and the discharge bin 6 are connected through a pair of spiral casings 7, a spiral shaft 8 is rotatably provided in the spiral casing 7, and a spiral blade 9 is provided on the spiral shaft 8, the support frame 2 is also provided with a driving motor 10 for driving the spiral shaft 8 to rotate, and a sealing mechanism is provided on the side wall of the discharge bin 6 toward the outlet of each spiral casing 7.
[0020] Bulk feed raw materials are generally stored in silos, but can also be stored in warehouses in small packages. Storing them in small packages can prevent the raw materials from becoming moldy due to direct stacking of bulk grains, which can cause large losses. Using small packages can also achieve the purpose of bagging, which is convenient for later transportation, feeding, etc.
[0021] In this device, if Figure 2 The four corners of the frame 1 are provided with weighing modules 11, and the weighing frame 3 is provided on the weighing modules 11. The four corners of the bottom of the weighing frame 3 are provided with eye screws 13, and each eye screw 13 is provided with a wide-mouth hook 14.
[0022] When the feed in the silo needs to be packaged and divided into bags using the device, first connect the silo outlet with the top of the feed silo, then hang the four hanging ropes on the sub-packaging bag to the corresponding wide-mouth hooks one by one, and then fix the bag mouth of the sub-packaging bag to the bottom of the lower hopper through the bag clamping mechanism. Finally, the feed can be divided into the sub-packaging bag, and the sub-packaging bag in this embodiment is a ton bag, and the ton bag has four hanging ropes.
[0023] The feed in the silo enters the feed bin, and at the same time, two drive motors drive their respective screw shafts to rotate. The feed is transported toward the discharge bin under the rotation of the spiral blades. The transported feed passes through the discharge bin and the lower hopper in turn, and finally falls into the packaging bag for packaging.
[0024] Since the sub-packaging bag is installed on the weighing frame through a wide-mouth hook, the actual weight of the feed in the sub-packaging bag can be measured by the weighing module during the process of sub-packaging the feed into the sub-packaging bag. When the feed in the sub-packaging bag reaches the required weight, the drive motor stops working immediately, the spiral blade stops conveying the feed, and the feed no longer falls into the discharge bin. Then the sealing mechanism closes the outlet of the spiral casing to further prevent the feed from falling into the discharge bin. Thus, the purpose of quantitative packaging of the feed is achieved.
[0025] In the actual packaging process, the wide-mouthed hook plays the role of hanging and supporting the packaging bag. On the one hand, it makes the feed more stable during packaging, and on the other hand, it also plays the role of opening the packaging bag.
[0026] In this structure, there is a notch above the spiral casing in the feed bin 5, so that the feed can fall into the feed bin normally. In addition, an air hammer 15 is provided on the side wall of the lower hopper 4. When the feed falls from the lower hopper to the sub-packaging bag, the air hammer works and hits the lower hopper to prevent the feed from accumulating in the lower hopper, thereby affecting the sub-packaging of the feed.
[0027] As a preferred structure, Figure 2-3 The sealing mechanism includes a sealing cylinder 16 and a pair of sliding sleeves installed on the discharge bin 6. The driving shaft of the sealing cylinder 16 is provided with a sealing pressure plate 18 matching the outlet of the spiral casing 7. A sliding rod 19 is inserted into each sliding sleeve, and the sliding rod 19 is connected to the sealing pressure plate 18.
[0028] When the outlet of the spiral casing is to be closed, the sealing cylinder drives the sealing plate to move toward the outlet of the corresponding spiral casing until the sealing plate is completely inserted into the outlet of the spiral casing. In this process, the sealing plate drives the two slide bars to slide in the sliding sleeve, making the entire sealing process more stable and the sealing effect better.
[0029] In addition, Figure 2 The bag clamping mechanism includes a fixed plate 20 installed on the lower hopper 4, and the fixed plate 20 is rotatably provided with two pairs of jaws 21, and a linkage rod 22 is provided between the same pair of jaws 21. A clamping block 23 is provided at the bottom of each jaw 21, and a clamping plate 24 is provided between the same pair of clamping blocks 23. A bag clamping cylinder 25 is rotatably provided on one pair of jaws 21, and the driving shaft of the bag clamping cylinder 25 is rotatably connected to the other jaw on the same side.
[0030] When it is necessary to clamp the bag opening of the sub-packaging bag under the lower hopper by means of a bag clamping mechanism, the sub-packaging bag is first inserted into the lower hopper, and the arc-shaped clamping plate is located outside the bag opening of the sub-packaging bag. Then, the two clamping cylinders are driven simultaneously to move the two clamping plates toward the bag opening of the sub-packaging bag until the bag opening of the sub-packaging bag is tightly attached to the lower hopper.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
