Description

Technical Field

[0001] The utility model belongs to the technical field of veterinary drug production, and particularly relates to an automatic bag-breaking device. Background Art

[0002] The primary production process for veterinary drug powders and premixes includes dosing, mixing, filling, and packaging. Veterinary excipients are typically packaged in plastic inner bags and woven outer bags. Due to the large production batches of powders and premixes, 6-9 tons of ingredients are typically batched per shift. Conventional dosing involves workers slashing the bags with a wallpaper knife and then feeding them into a mixing tank via a dosing platform. Assuming each bag weighs 25 kg, workers would need to break 240-360 bags per day, taking 30 seconds per bag. This translates to a daily bag-breaking time of 2-3 hours, resulting in high labor intensity and low production efficiency. Utility Model Content

[0003] In order to solve the problem that manual bag breaking in the existing technology causes high labor intensity and low production efficiency for workers, the utility model provides an automatic bag breaking device. The mounting plate and the feed plate can be rotated by a telescopic rod. At this time, the end of the feed plate with a strip hole moves downward, and the top of the blade leaks out through the corresponding strip hole. The packaging bag on the feed plate slides downward along the feed plate under the action of gravity. The packaging bag will be automatically broken when it passes through the blade, thereby achieving the purpose of automatic bag breaking.

[0004] The technical solution adopted by the automatic bag breaking device of the utility model is:

[0005] An automatic bag breaking device includes a dust-free feeding machine. The feeding port of the dust-free feeding machine is provided with several vertical parallel blades, and the cutting edge of each blade is facing the outside of the dust-free feeding machine. At the same time, a feed plate that can rotate in the vertical direction is provided on the outside of the feeding port of the dust-free feeding machine. One end of the feed plate extends above the feeding port of the dust-free feeding machine, and a strip hole is opened at the end of the feed plate located above the feeding port of the dust-free feeding machine at the position corresponding to each blade.

[0006] A further improvement of the technical solution of the present invention is that a feeding rack placed on the ground is provided outside the feeding port of the dust-free feeding machine, and a mounting plate connected to the feeding plate is hinged on the top of the feeding rack.

[0007] A further improvement of the technical solution of the present utility model is that: the mounting plate is located on the top of the feeding rack and is parallel to the feeding plate, and one end of the mounting plate close to the feeding port of the dust-free feeding machine is hinged to the other end of the feeding rack close to the feeding port of the dust-free feeding machine, and the bottom of the other end of the mounting plate is connected to the feeding rack through a telescopic rod.

[0008] A further improvement of the technical solution of the present invention is that a connecting mechanism for connecting the blade and the feeding port is provided at the bottom of the feeding port of the dust-free feeding machine corresponding to the position of each blade.

[0009] A further improvement of the above technical solution of the present invention is that: the connecting mechanism includes a connecting piece vertically fixed at the bottom of the feeding port, and the bottom end of the blade is detachably connected to the connecting piece; wherein, the position of the feeding port corresponding to each blade is provided with an extension hole for the blade to extend.

[0010] A further improvement of the above technical solution of the present invention is that: each connecting piece is provided with a plurality of first connecting holes, and one end of the blade is provided with second connecting holes corresponding to the plurality of first connecting holes.

[0011] A further improvement of the technical solution of the present utility model is that a plurality of feeding rollers are hingedly connected to the feeding plate along its width direction.

At this time, the end of the feeding plate with the strip hole is rotated downward. When the feeding plate is rotated to a certain angle, the blade will pass through the strip hole upward, thereby expelling the blade; the feeding plate that is tilted after rotation can make the packaging bag slide along the feeding plate toward the feeding port under the action of its own gravity. When the packaging bag slides over the blade, the blade will automatically break the packaging bag, thereby saving labor and improving production efficiency.

[0015] At the same time, the blade in the utility model is connected to the feeding port through a connecting mechanism, so when the blade is damaged after long-term use, it is convenient to replace the damaged blade.

[0016] The supporting net provided in the present invention can conveniently receive the packaging bag after the bag is broken.

The dust-free feeder 1 can be specifically configured with reference to Figure 2 ,according to Figure 2 It can be seen that the position of the feeding port 11 inside the dust-free feeding machine 1 is fixedly connected with a horizontal support net 13, which includes multiple horizontal and mutually parallel support rods, and there is a large gap between two adjacent support rods; continue to refer to Figure 2 , the interior of the dust-free feeder 1 is fixedly connected to a horizontal screen 14 at a position below the support net 13; continue to refer to Figure 2 A plurality of vertical blades 2 are provided at the feeding port 11 , and the cutting edge of each blade 2 faces the outside of the dust-free feeder 1 .

[0028] The blade 2 is connected to the feeding port 11 via a connecting mechanism 5. The specific configuration of the connecting mechanism 5 may refer to Figure 3 ,according to Figure 3 It can be seen that the connecting mechanism 5 includes a vertical connecting piece 51 fixedly connected to the bottom of the feeding port 11, and a plurality of first connecting holes 52 are opened on the connecting piece 51. At the same time, the bottom end of each blade 2 is opened with a second connecting hole 21 corresponding to the plurality of first connecting holes 52. When the blade 2 and the connecting piece 51 are connected, the second connecting holes 21 and the first connecting holes 52 are connected together in a one-to-one correspondence, and then the blade 2 and the connecting piece 51 are fixedly connected together by bolts and nuts; continue to refer to Figure 3 It can be seen that the position of each blade 2 corresponding to the feeding port 11 is provided with an extension hole 12 for facilitating the blade 2 to extend upward.

[0029] Continue to refer Figure 1 The outside of the feeding port 11 is provided with a feeding rack 4 placed on the ground. The feeding rack 4 can be referred to in the specific setting. Figure 4 ,according to Figure 4 It can be seen that a mounting plate 41 is provided above the feed rack 4, and at the same time, the end of the mounting plate 41 close to the dust-free feeder 1 is hinged to the end of the feed rack 4 close to the dust-free feeder 1 through a rotating shaft 42, and the bottom of the other end of the mounting plate 41 is connected to the feed rack 4 through an inclined telescopic rod 43. The above-mentioned telescopic rod 43 can adopt the electric telescopic rod 43, hydraulic telescopic rod 43 and pneumatic telescopic rod 43 commonly used in the prior art. Specifically, the top end of the telescopic rod 43 is connected to the mounting plate 41 through an ear seat, and the bottom end of the telescopic rod 43 is also connected to the feed rack 4 through the ear seat. At the same time, a switch for controlling the above-mentioned telescopic rod 43 is provided in the utility model, and the switch can adopt the foot-operated switch commonly used in the prior art.

[0030] Continue to refer Figure 4 As can be seen, a feed plate 3 is fixedly connected to the top of the mounting plate 41 and is parallel to the mounting plate 41. The end of the feed plate 3 near the dust-free feeder 1 extends above the feed inlet 11. At the same time, the end of the feed plate 3 above the feed inlet 11 is provided with a strip hole 31 corresponding to the position of each blade 2. A plurality of feed rollers 32 are hingedly connected to the feed plate 3 and arranged along the width direction of the feed plate 3. When the mounting plate 41 and the feed plate 3 are in a horizontal state, the feed plate 3 is higher than the top of the blade 2.

[0031] The working principle of the automatic bag breaking device of this embodiment is as follows: when the present invention is used, the packaging bag placed on the ground is first sucked up by the vacuum air pipe suction hoist, and then the packaging bag is moved to the feeding plate 3. At this time, the worker steps on the switch, and the telescopic rod 43 begins to extend to rotate the mounting plate 41 and the feeding plate 3 until the blade 2 leaks out of the strip hole 31 of the feeding plate 3. Figure 5 shown.

[0032] At this time, the packaging bag moves on the feeding plate 3 toward the dust-free feeder 1 under the action of its own gravity. When the packaging bag passes through the blade 2 during the movement, the blade 2 will break the packaging bag. The broken packaging bag enters the dust-free feeder 1 through the feeding port 11, and the packaging bag will fall on the support net 13. The material in the packaging bag falls on the screen 14 through the support net 13 for screening. When the material in the packaging bag has completely fallen, the packaging bag above the support net 13 can be taken out manually.

[0033] At the same time, the worker no longer steps on the switch, and the telescopic rod 43 contracts until it returns to its original position. Figure 1 status, making it convenient to place the packaging bag next time.

[0034] In the above embodiment, the utility model provides an automatic bag breaking device, which can rotate the mounting plate and the feeding plate in the vertical direction with one end of the mounting plate and the feeding frame hinged as the center through the telescopic rod. At this time, the end of the feeding plate with the strip hole rotates downward. When the feeding plate rotates to a certain angle, the blade will pass through the strip hole upward, thereby expelling the blade; after rotation, the tilted feeding plate can make the packaging bag slide along the feeding plate toward the feeding port under the action of its own gravity. When the packaging bag slides over the blade, the blade will automatically break the packaging bag, thereby saving labor and improving production efficiency.

[0035] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content sought to be protected by the present invention is fully set forth in the claims.
