Description

Technical Field

[0001] The utility model belongs to the field of feed processing, and particularly relates to a feed filling device. Background Art

[0002] At present, feed processing enterprises basically use silos to store bulk feed raw materials. Feed processing enterprises that do not apply silos can only store them in the form of traditional small packages in the warehouse. Packaging and sub-packaging feed in small packages can prevent feed from piling up and causing raw material mildew. In addition, filling and sub-packaging feed in small packages is also convenient for transporting feed and subsequent feeding.

[0003] When the existing packaging bags are filled, generally only the bag mouth of the packaging bag is clamped by a bag clamping mechanism, or the packaging bag is hung on the rack. Then the outlet of the filling hopper is opened. At this time, the feed is filled from the filling hopper into the packaging bag. Although filling can be completed in this way, during the filling process, the packaging bag is prone to shaking, affecting the filling quality and the feed is also prone to falling to the ground. In addition, during the filling process, the flow rate of the feed filled into the canned bag cannot be controlled. Summary of the Utility Model

[0004] In view of the above problems, the purpose of the utility model is to provide a feed filling device, aiming to solve the problem that the packaging bag is prone to shaking during the filling process of the existing feed filling device, which affects the filling quality.

[0015] In order to make the patent purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0016] In order to illustrate the technical solution described in the present utility model, the following will be described through specific embodiments.

[0017] For the convenience of description, only the parts related to the embodiments of the present utility model are shown.

[0018] Combined with Figures 1-3As shown, the filling device includes a frame 1, and the frame 1 is respectively provided with a filling mechanism and a bag supporting mechanism at the top and the bottom. The filling mechanism includes a bracket 2 installed on the frame 1, and a filling hopper 3 is provided in the bracket 2. A control component for controlling the size of the filling hopper outlet is provided at the bottom of the filling hopper 3. A pair of bag clamping components are provided downwardly on the bracket 2. The bag supporting mechanism includes a base 5, and a carrier 6 and a slide 7 are respectively provided in the base 5 and at the front and rear. The carrier 6 is located directly below the filling hopper 3, and a pair of clamping arms are respectively provided at the front and rear of the slide 7, wherein the front clamping arm is marked 81 and the rear clamping arm is marked 82. The front clamping arm 81 is lower than the rear clamping arm 82, and a bag supporting plate 9 is provided inwardly at the top of the front clamping arm 81, and an adjusting cylinder 10 is provided at the top of the rear clamping arm 82. The driving shaft of the adjusting cylinder 10 is provided with a top seat 11, and the top seat 11 is provided with a bag pressing plate 12 inwardly. A clamping cylinder 13 for driving the clamping arm to rotate is provided on the slide 7, and a driving mechanism for driving the slide 7 to slide is provided in the base 5.

[0019] In this structure, a worm gear lifter 14 is provided in the base 5, and the lifting shaft of the worm gear lifter is connected to the carrier. When using this device to fill feed, firstly, the two ends of the bag opening of the packaging bag are clamped by the bag clamping assembly. At this time, the outlet of the filling hopper is located in the bag opening of the packaging bag. Then, the carrier moves upward for a short distance under the drive of the worm gear lifter. The carrier supports the bottom of the packaging bag, and the slide slides forward to the filling position. At this time, the two bag pressing plates are in an open state, and the clamping cylinder drives the two bag supporting plates to move toward the packaging bag, and the two bag supporting plates support the packaging bag. Finally, the control component opens the outlet of the filling hopper, and the feed can be filled into the packaging bag.

[0020] In this device, if Figure 2 The driving mechanism includes a driving motor 4 mounted on a base 5, a linkage arm 15 is rotatably provided on the driving shaft of the driving motor 4, a push-pull rod 16 is rotatably provided at the end of the linkage arm 15, and the push-pull rod 16 is rotatably connected to the corresponding position of the slide seat 7.

[0021] When the packaging bag is filled, the corresponding two clamping cylinders simultaneously drive the two clamping arms at the rear to move toward the bag opening of the packaging bag until the two bag pressing plates clamp the bag opening of the packaging bag. The two bag supporting plates further clamp and support the packaging bag, and finally the driving motor drives the linkage arm to rotate, and the push-pull rod pushes the slide seat to move backward to the next station under the linkage of the linkage arm. In actual situations, the height of the bag pressing plate can be fine-tuned, so that different positions of the bag opening need to be clamped according to the actual situation on site. When the height of the bag pressing plate needs to be fine-tuned, the two adjusting cylinders can drive the corresponding top seat at the same time.

[0022] As a preferred structure, Figure 3, the control assembly includes two side plates 17 whose rotating shafts are connected to the bottom of the filling hopper 3 and are arranged oppositely. Control cylinders 18 are rotatably provided on the side walls of the filling hopper 3 respectively towards the side plates 17, and the driving shafts of the control cylinders 18 are rotatably connected to the side plates 17 on the same side.

[0023] When the packaging bag is clamped by the bag clamping assembly and the filling hopper outlet is located inside the bag mouth of the packaging bag, the control assembly controls the opening angle of the two side plates to control the flow rate of the feed and thus control the filling speed. Specifically: when it is necessary to control the opening angle of the two side plates, the two control cylinders are driven simultaneously, and the driving shafts of the control cylinders drive the two side plates to open at a certain angle.

[0024] The bag clamping assembly includes a fixed seat 24. A linkage block 19 is rotatably provided inside the fixed seat. A gripper 20 is rotatably provided at the bottom of the linkage block 19. Clamping blocks 21 are provided on the inner wall of the gripper 20. An adjusting cylinder 21 is also provided on the fixed seat 24, and the driving shaft of the adjusting cylinder 21 is rotatably connected to the middle of the linkage block 19.

[0025] In this embodiment, a bag gripper is also provided on the frame corresponding to the filling assembly. Before the feed is filled, the bag gripper clamps the packaging bag and moves towards the filling hopper. Before that, the two grippers rotate outwards under the drive of the adjusting cylinder and the grippers are in an open state, reserving an avoidance space. After the bag gripper picks up the bag and rotates into place towards the filling hopper, the grippers reset. At this time, the grippers are located above the bag mouth of the packaging bag. The bag gripper continues to rotate towards the filling hopper until both ends of the packaging bag are sent to the grippers on the same side, and then the two grippers clamp the bag mouth of the packaging bag. Then the two grippers continue to rotate towards the filling hopper, making the bag mouth of the packaging bag loose and automatically open at a certain angle. The insertion knife on the bag gripper rotates towards the inside of the bag mouth of the packaging bag until it is inserted into the bag. At this time, the bag mouth of the packaging bag is in an open state and corresponds to the filling hopper outlet, and the control assembly controls the size of the filling hopper outlet for filling. Since the bag gripper is not the key content of this device, it will not be described in detail here.

[0026] In addition, a blocking frame 22 is rotatably provided downward on the side plate 17, and a blocking cylinder 23 is rotatably provided on the side plate 17. The driving shaft of the blocking cylinder 23 is rotatably connected to the blocking frame 22. When the two side plates are located in the bag mouth of the packaging bag, at this time, the blocking cylinder drives the blocking frame to move towards the packaging bag until the bag mouth is clamped. The control assembly can then control the two side plates to open for filling. Using the blocking frame to clamp further clamps the bag mouth, thereby improving the stability during filling.

[0027] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the invention shall be included in the protection scope of the present invention.
