Description

Technical Field

[0001] This utility model relates to the field of waste cardboard box processing technology, specifically a feeding device for compressing and baling waste cardboard boxes. Background Technology

[0002] Waste cardboard box compression baling is an environmentally friendly processing technology that mechanically compresses waste cardboard boxes into high-density blocks or packages. When compressing and baling waste cardboard boxes, a feeding device is needed to automatically or semi-automatically feed the waste cardboard boxes into the compression chamber to achieve efficient and continuous material conveying and improve the overall baling efficiency.

[0003] Currently, waste cardboard box compression and baling feeding devices typically use conveyor belts to load waste cardboard boxes. However, existing conveyor belts lack effective anti-tipping structures for the waste cardboard boxes. During use, when the waste cardboard boxes are transported to a high place, they are prone to falling back due to gravity. At the same time, there are usually no interception devices on the conveyor belts to prevent the falling waste cardboard boxes from causing accidental injuries to workers.

[0004] Therefore, there is a need for a feeding device for compressing and baling waste cardboard boxes to solve the problem that existing feeding devices for compressing and baling waste cardboard boxes are prone to dropping back during use, and that the falling waste cardboard boxes can easily cause accidental injury to workers. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding device for compressing and baling waste cardboard boxes, so as to solve the problem that the feeding device for compressing and baling waste cardboard boxes in the prior art is prone to the phenomenon of cardboard boxes falling back during use, and the falling waste cardboard boxes are likely to cause accidental injury to the workers.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for compressing and baling waste paper boxes, comprising a feeding port, a frame installed at one end of the feeding port, and a conveyor belt installed inside the frame, wherein the conveyor belt is provided with a plurality of blocking structures, and the frame is provided with an anti-fall-back component.

[0007] Each of the aforementioned barrier structures includes a baffle installed on the conveyor belt, placement slots on both sides of the baffle, a guide rod installed between the two side walls inside the placement slot, a movable block movably installed on the guide rod, a transverse baffle installed on one side of the movable block and sliding through one side of the baffle, a drive cavity opened inside the baffle, a bidirectional lead screw rotatably installed inside the two placement slots, a worm gear rotatably installed inside the drive cavity, and a drive bevel gear fastened to the worm gear. A worm wheel is fastened to the outside of the bidirectional lead screw located in the drive cavity. One end of the worm gear rotatably passes through one end of the baffle and is coaxially mounted with a screw cap.

[0008] It should be noted in the scheme that each of the barrier structures also includes a U-shaped groove formed on the top surface of the barrier bar, a vertical baffle plate movably installed inside the two vertical sections of the U-shaped groove, a lifting screw rotatably installed inside the transverse section of the U-shaped groove and whose bottom end extends into the drive cavity, a connecting plate movably installed on the lifting screw, and a driven bevel gear installed at the bottom end of the lifting screw.

[0009] It is worth noting that the anti-fall-back assembly includes arc-shaped shells installed on both sides inside the frame, arc-shaped grooves opened on the top and bottom surfaces of the arc-shaped shells, an anti-fall-back plate rotatably installed inside the arc-shaped shells, a spring installed between one side of the arc-shaped shells and one end of the anti-fall-back plate, and pins installed on the top and bottom surfaces of the anti-fall-back plate, respectively slidingly engaging with the two arc-shaped grooves.

[0010] Furthermore, it should be noted that the two moving blocks within each of the stop bars are threadedly connected to the corresponding bidirectional lead screw, and each of the worms is meshed with the corresponding worm wheel.

[0011] In a preferred embodiment, each of the connecting plates is connected to two corresponding vertical baffles, and each of the driving bevel gears is meshed with a corresponding driven bevel gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By rotating the screw cap, the worm gear is driven to rotate, which in turn drives the worm wheel to rotate the bidirectional lead screw. This drives the moving block to move the horizontal baffle out of the placement slot. The rotation of the worm gear drives the active bevel gear to rotate, which in turn drives the driven bevel gear to rotate the lifting lead screw. This drives the connecting plate to move the vertical baffle out of the U-shaped slot, so that the baffle can block waste paper boxes of different sizes and prevent the waste paper boxes from falling back during transportation.

[0014] 2. The anti-fall-back plates, which can rotate in one direction, rotate during the conveying of waste paper boxes to avoid interfering with the conveying process. If a waste paper box falls back, the two anti-fall-back plates will intercept the waste paper box to prevent accidental injury to the staff. Attached Figure Description

[0021] 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.

[0022] Example: Figures 1-5 As shown, this utility model provides a technical solution, including a feeding port 1, a frame 2 installed at one end of the feeding port 1, and a conveyor belt 3 installed inside the frame 2. The conveyor belt 3 is provided with a plurality of blocking structures 4, and the frame 2 is provided with an anti-fall-back component 5.

[0023] Each barrier structure 4 includes a baffle 41 mounted on the conveyor belt 3, placement slots 42 on both sides of the baffle 41, a guide rod 43 mounted between the two side walls inside the placement slot 42, a movable block 44 mounted on the guide rod 43, a transverse baffle 45 mounted on one side of the movable block 44 and sliding through one side of the baffle 41, a drive cavity 46 inside the baffle 41, a bidirectional lead screw 47 rotatably mounted inside the two placement slots 42, a worm gear 48 rotatably mounted inside the drive cavity 46, and a drive bevel gear 49 fastened to the worm gear 48. A worm wheel 410 is fastened to the outside of the bidirectional lead screw 47 located in the drive cavity 46. One end of the worm gear 48 rotatably passes through one end of the baffle 41 and is coaxially mounted with a cap 411.

[0024] Specifically, rotating the screw cap 411 drives the worm gear 48 to rotate, which in turn drives the worm wheel 410 to rotate, thereby driving the double-acting screw 47 to rotate. The double-acting screw 47 drives two moving blocks 44 to move on the guide rod 43, which in turn moves the transverse baffle 45 out of the placement slot 42 to help extend the transverse length of the baffle 41, so that the baffle 41 can block waste paper boxes of different sizes.

[0025] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that each barrier structure 4 also includes a U-shaped groove 412 formed on the top surface of the baffle 41, a vertical baffle 413 movably installed inside the two vertical sections of the U-shaped groove 412, a lifting screw 414 rotatably installed inside the transverse section of the U-shaped groove 412 and extending to the drive cavity 46 at its bottom end, a connecting plate 415 movably installed on the lifting screw 414, and a driven bevel gear 416 installed at the bottom end of the lifting screw 414.

[0026] Specifically, when the worm gear 48 rotates, it drives the driving bevel gear 49 to rotate. The driving bevel gear 49 drives the driven bevel gear 416 to rotate, thereby driving the lifting screw 414 to rotate. The lifting screw 414 drives the connecting plate 415 to move upward, thereby causing the vertical baffle 413 to move out of the U-shaped groove 412, which is used to help extend the vertical length of the baffle 41 and further improve the applicability of the baffle 41.

[0027] Further as Figure 1 and Figure 5 As shown, it is worth noting that the anti-falling assembly 5 includes an arc-shaped shell 51 installed on both sides inside the frame 2, an arc-shaped groove 52 formed on the top and bottom surfaces of the arc-shaped shell 51, an anti-falling plate 53 rotatably installed inside the arc-shaped shell 51, a spring 54 installed between one side of the arc-shaped shell 51 and one end of the anti-falling plate 53, and pins 55 installed on the top and bottom surfaces of the anti-falling plate 53 respectively, which slide in cooperation with the two arc-shaped grooves 52.

[0028] Specifically, when the waste paper box is conveyed on the conveyor belt 3, it pushes the two anti-fall plates 53. After being subjected to force, the two anti-fall plates 53 rotate inside the arc-shaped shell 51. The rotation of the anti-fall plates 53 is guided by the sliding cooperation between the pin 55 and the arc-shaped groove 52. At the same time, the anti-fall plates 53 squeeze the spring 54. After the waste paper box passes through the two anti-fall plates 53, the spring 54 pushes the anti-fall plates 53 to reset and rotate. When the waste paper box falls back, the two anti-fall plates 53 intercept the waste paper box to prevent accidental injury to the staff.

[0029] Further as Figure 2 and Figure 3As shown, it is worth noting that the two moving blocks 44 in each stop bar 41 are threadedly connected to the corresponding bidirectional lead screw 47, and each worm 48 is meshed with the corresponding worm wheel 410.

[0030] Specifically, the two moving blocks 44 in each stop bar 41 are threadedly connected to the corresponding double-acting screw 47, which is used to drive the two moving blocks 44 to move by rotating the double-acting screw 47. Each worm 48 is meshed with the corresponding worm wheel 410, which is used to drive the worm wheel 410 to rotate by rotating the worm 48, thereby driving the double-acting screw 47 to rotate.

[0031] Further as Figure 3 and Figure 4 As shown, it is worth noting that each connecting plate 415 is connected to two corresponding vertical baffles 413, and each driving bevel gear 49 is meshed with the corresponding driven bevel gear 416.

[0032] Specifically, each connecting plate 415 is connected to two corresponding vertical baffles 413, which are used to move the vertical baffles 413 by the lifting and lowering movement of the connecting plate 415. Each driving bevel gear 49 is meshed with the corresponding driven bevel gear 416. When the worm gear 48 drives the driving bevel gear 49 to rotate, it drives the driven bevel gear 416 to drive the lifting screw 414 to rotate.

[0033] In summary: When using this feeding device, rotating the screw cap 411 drives the worm gear 48 to rotate, which in turn drives the worm wheel 410 to rotate, thereby driving the double-acting screw 47 to rotate. Under the action of the screw thread, the double-acting screw 47 drives two moving blocks 44 to move on the two guide rods 43 respectively. The two moving blocks 44 drive the two transverse baffles 45 to move out of the placement groove 42, thus extending the transverse length of the baffle 41. At the same time, when the worm gear 48 rotates, it drives the driving bevel gear 49 to rotate. Under meshing action, the driving bevel gear 49 drives the driven bevel gear 416 to rotate, thereby driving the lifting screw 414 to rotate. The lifting screw 414 drives the connecting plate 415 to move upward, thereby driving the two vertical baffles 413 to move upward and out of the U-shaped groove 412, thus extending the vertical length of the baffle 41. After the baffle 41 is adjusted, the conveyor belt 3 is turned on, and the waste paper box is placed on the conveyor belt 3. The baffle 41 then aligns with the upper part of the waste paper box. The waste cardboard boxes in the material are blocked to prevent them from rolling down the conveyor belt 3 when they reach a high position. The adjustable baffle 41 can limit and block waste cardboard boxes of different sizes, improving the practicality of the feeding device. When the waste cardboard boxes are conveyed on the conveyor belt 3, they push the two anti-fall plates 53. The two anti-fall plates 53 rotate under the force. The rotation of the anti-fall plates 53 is guided by the sliding cooperation between the pin 55 and the arc groove 52. At the same time, the anti-fall plates 53... The spring 54 is compressed, and after the waste cardboard box passes through the two anti-fall plates 53, the anti-fall plates 53 are pushed to reset and rotate under the action of the spring 54. If the waste cardboard box falls back on the conveyor belt 3, the two anti-fall plates 53 intercept the falling waste cardboard box to prevent the falling waste cardboard box from causing accidental injury to the staff. This effectively avoids the problem that the waste cardboard box compression and baling feeding device is prone to falling back during use, and that the falling waste cardboard box is likely to cause accidental injury to the staff.
