Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging, and in particular to a flip-type super-volume sorting structure. Background Technology
[0002] The existing automated metering packaging machines and automated feeding and pressing machines all use the method of pouring materials into hoppers, bins or other material containers, and then feeding them from the bottom outlet of the material container into the metering mechanism through a vibrating feeding structure or auger feeding mechanism. The metering mechanism weighs or counts the materials according to the set amount to obtain fixed packaged materials. These fixed packaged materials come out from the bottom outlet of the metering mechanism, and then enter the inlet of the packaging machine or pressing machine through the guide chute, where they are automatically packaged or automatically pressed. Although this material packaging method uses intelligent control in the vibratory feeding and auger feeding processes, different materials vary in shape, size, viscosity, and flowability. Therefore, overweight and over-quantity issues often occur during packaging. If these overweight and over-quantity materials are packaged and pressed without undergoing overweight screening and are directly sold in the market, it will cause huge losses and waste for manufacturers over time. If overweight screening is performed, the materials need to be decomposed and repackaged, which avoids production packaging losses, but the packaging bags need to be replaced, resulting in waste of packaging materials, wasting time, and low work efficiency.
[0003] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content
[0004] The purpose of this utility model is to provide a flip-type overload sorting structure to solve the problem of high cost and low efficiency caused by the inability to remove overweight or overloaded materials before packaging.
[0005] To achieve the above objectives, this utility model adopts the following technical solution:
[0006] A flip-type oversized sorting structure includes a frame and a quantitative hopper and a discharge hopper mounted on the frame. The quantitative hopper and the discharge hopper are connected and cooperate. The discharge hopper has a switching hopper, a first discharge hopper, and a second discharge hopper. The output end of the quantitative hopper is connected to the input end of the switching hopper, and the output end of the switching hopper is connected and cooperates with the input ends of the first discharge hopper and the second discharge hopper. The switching hopper is rotatably mounted on the frame, and a rotation switching drive device is installed on the frame to control the switching hopper's output end to switch relative to the input end of the first discharge hopper or relative to the input end of the second discharge hopper.
[0007] The aforementioned switching hopper is located below the quantitative hopper and above the first and second discharge hoppers, which are arranged horizontally.
[0008] Both the first and second hoppers have downward-sloping output channels, and the two inclined output channels may be in the same or different directions.
[0009] With the horizontal arrangement of the first and second hoppers as the left-right direction, the first hopper is on the left and the second hopper is on the right. The first hopper consists of a front inclined plate, a rear inclined plate, a left vertical plate, and a right vertical plate. Both the front and rear inclined plates are downward inclined plates that slope from back to front, and the lower end of the rear inclined plate extends forward to the outside of the lower end of the front inclined plate. The second hopper consists of a left inclined plate, a right inclined plate, a front vertical plate, and a rear vertical plate. Both the left and right inclined plates are downward inclined plates that slope from left to right, and the lower end of the left inclined plate extends to the outside of the lower right side of the right inclined plate.
[0010] The aforementioned switching hopper has a material passage that switches and cooperates with the first and second feeding hoppers, and the aforementioned switching hopper is driven by a circumferential rotation device that switches the material passage and guides the switching between the first and second feeding hoppers. This circumferential rotation drive device is the aforementioned rotation switching drive device.
[0011] The aforementioned switching bucket is a cone bucket that gradually narrows from top to bottom. A mounting plate is fixed on the outer wall of the cone bucket, and a rotation drive device for driving the mounting plate to rotate is mounted on the mounting plate. This rotation drive device is the aforementioned rotation switching drive device.
[0012] The aforementioned switching bucket is a swing bucket capable of lateral swinging. The swing bucket has two vertically penetrating connecting channels, which are arranged laterally. The lateral arrangement direction of the two connecting channels is the same as the lateral arrangement direction of the first and second feeding hoppers. The lateral swinging direction of the swing bucket is the same as the lateral arrangement direction of the two connecting channels. The aforementioned frame is equipped with a swing driving device that drives the swing bucket to swing along the lateral arrangement direction of the two connecting channels. The aforementioned swing driving device is the aforementioned rotation switching driving device.
[0013] With the lateral arrangement of the two connecting channels as the left-right direction, the aforementioned swing bucket has a front side plate, a rear side plate, and a partition plate between the front side plate and the rear side plate. The partition plate, the left side of the front side plate, and the left side of the rear side plate form a left-side open and vertically connected channel, which is one of its connecting channels. The partition plate, the right side of the front side plate, and the right side of the rear side plate form a right-side open and vertically connected channel, which is another connecting channel. The front side plate is rotatably mounted on the front side wall of the receiving channel via a rotating shaft, and the aforementioned swing drive device is installed on the outside of the rear side plate.
[0014] The aforementioned swing drive device includes a drive motor and a swing arm. The swing arm is upright, and the output shaft of the drive motor is connected to the swing arm in a manner that drives the first end of the swing arm to rotate. The second end of the swing arm is connected to the swing arm in a manner that drives the swing bucket to swing left and right.
[0015] With the above technical solution, the present invention provides a flip-type over-sorting structure, which is installed between the weighing mechanism and the packaging mechanism. The first hopper is aligned with the packaging mechanism, and the second hopper is aligned with the collection bin. The initial state is that the first hopper is connected to the switching hopper. In application, if the material output from the quantitative hopper meets the packaging quantity required by the packaging mechanism, the material is directly output from the quantitative hopper through the switching hopper and the first hopper to the packaging mechanism for packaging. If the material output from the quantitative hopper exceeds the required packaging quantity, the switching drive device is activated to align and connect the switching hopper and the second hopper. The material in the quantitative hopper is then output through the switching hopper and the second hopper to the collection bin for collection and repackaging. Compared with existing technologies, by utilizing the switching hopper in conjunction with the switching and conduction of the first and second feeding hoppers, overweight and excessive materials can be rejected, ensuring that the materials packaged by the packaging mechanism are always accurately packaged and the packaging is stable. This avoids the problems of high packaging costs and low efficiency for manufacturers caused by the inaccurate weighing of traditional weighing mechanisms. Moreover, overweight and excessive materials in the quantitative hopper are directly recycled to the weighing mechanism for re-weighing and packaging, making the operation convenient.

[0024] To further explain the technical solution of this utility model, a detailed description is provided below in conjunction with the accompanying drawings.
[0025] This utility model provides a flip-type overload sorting structure, as shown in Embodiment 1. Figure 1 , 2 As shown, the device includes a frame (not shown in the figure) and a metering hopper 1 and a discharging hopper mounted on the frame. The metering hopper 1 and the discharging hopper are connected and cooperate with each other. The metering hopper is an existing hopper and is a known technology. It can be a weighing hopper or a counting hopper, and is not limited here.
[0026] The improvement of this invention is that the feeding hopper has a switching hopper 2, a first feeding hopper 3, and a second feeding hopper 4. The output end of the quantitative feeding hopper 1 is connected to the input end of the switching hopper 2. The output end of the switching hopper 2 is connected to the input end of the first feeding hopper 3 and the input end of the second feeding hopper 4. The switching hopper 2 is rotatably mounted on the frame, and the frame is equipped with a rotation switching drive device that controls the switching of the output end of the switching hopper to be in a relative position with the input end of the first feeding hopper or with the input end of the second feeding hopper.
[0027] Preferably, the switching hopper 2 is located below the quantitative hopper 1 and above the first discharge hopper 3 and the second discharge hopper 4. The first discharge hopper 3 and the second discharge hopper 4 are arranged horizontally, with the horizontal arrangement of the first discharge hopper 3 and the second discharge hopper 4 as the left-right direction. The first discharge hopper is on the left and the second discharge hopper is on the right. Both the first discharge hopper 3 and the second discharge hopper 4 have downward-sloping inclined output channels, and the two inclined output channels have different inclination directions. That is, the inclined channel of the first discharge hopper 3 is inclined downward from back to front, or it can be inclined downward from front to back. Correspondingly, the inclined channel of the second discharge hopper 4 is inclined downward from left to right. The direction of the two inclined channels is not restricted.
[0028] Taking the inclined channel of the first hopper 3 as being inclined downward from back to front and the inclined channel of the second hopper 4 as being inclined downward from left to right as an example, the first hopper 3 is composed of a front inclined plate, a rear inclined plate, a left vertical plate and a right vertical plate. The front inclined plate and the rear inclined plate are both downward inclined plates that slope downward from back to front. The lower end of the rear inclined plate extends forward to the outside of the lower end of the front inclined plate. The front inclined plate, the rear inclined plate, the left vertical plate and the right vertical plate form a downward inclined channel from back to front. The second hopper 4 is composed of a left inclined plate, a right inclined plate, a front vertical plate and a rear vertical plate. The left inclined plate and the right inclined plate are both downward inclined plates that slope downward from left to right. The lower end of the left inclined plate extends to the outside of the lower right side of the right inclined plate. The left inclined plate, the right inclined plate, the front vertical plate and the rear vertical plate form a downward inclined channel from left to right.
[0029] The switching hopper 2 is a material passage with only one receiving and cooperating with the first feeding hopper 3 and the second feeding hopper 4. The switching hopper 3 is a circumferential rotation drive device that switches the material passage with the first feeding hopper and the second feeding hopper by rotating circumferentially. This circumferential rotation drive device is the aforementioned rotation switching drive device.
[0030] Specifically, the switching hopper 2 is a tapered cone hopper that tapers from top to bottom. A mounting plate 5 is fixed to the outer wall of the cone hopper, and a rotation drive device is mounted on the mounting plate 5 to drive its rotation. This rotation drive device is the aforementioned rotation switching drive device. The mounting plate 5 is an L-shaped plate, with its vertical portion fixed to the outer wall of the switching hopper 2 and its horizontal portion extending outwards. Below the horizontal portion of the mounting plate is a motor drive device that drives its rotation. This motor drive device consists of only one motor, which is directly mounted on the frame. The output end of the motor is fixedly connected to the horizontal portion with its upward-facing end. The output shaft of the motor can be located between the first and second feeding hoppers, or behind them. The motor drive device can also use a combination of a motor and a transmission mechanism. Alternatively, a rotary cylinder drive can be used; any method that can drive the switching hopper to rotate can be directly replaced. In application, the center of the horizontal part of the mounting plate is not on the same straight line as the center of the switching hopper 2. This way, when the mounting plate rotates 360 degrees in the circumferential direction, the lower end of the switching hopper 2 can be switched and aligned with the first or second feeding hopper.
[0031] This utility model discloses a flip-type overload sorting structure, which is installed between a weighing mechanism and a packaging mechanism. The first feeding hopper 3 is aligned with the packaging mechanism, and the second feeding hopper 4 is aligned with the collection bucket. The initial state is that the first feeding hopper 3 is connected to the switching hopper 2. In application, if the material output from the quantitative feeding hopper 1 meets the packaging quantity required by the packaging mechanism, the material is directly output from the quantitative feeding hopper, passes through the switching hopper and the first feeding hopper 3, and is packaged in the packaging mechanism. If the material output from the quantitative feeding hopper 1 exceeds the required packaging quantity, the drive motor is started, causing the switching hopper 2 to rotate. The lower end of the switching hopper 2 is aligned and connected with the second feeding hopper 4, and the material in the quantitative feeding hopper 1 is output through the switching hopper 2 and the second feeding hopper 4 to the collection bucket for collection and repackaging. Compared with existing technologies, by utilizing the switching hopper in conjunction with the switching and conduction of the first and second feeding hoppers, overweight and excessive materials can be rejected, ensuring that the materials packaged by the packaging mechanism are always accurately packaged and the packaging is stable. This avoids the problems of high packaging costs and low efficiency for manufacturers caused by the inaccurate weighing of traditional weighing mechanisms. Moreover, overweight and excessive materials in the quantitative hopper are directly recycled to the weighing mechanism for re-weighing and packaging, making the operation convenient.
[0032] A second embodiment of this utility model, such as Figure 3 , 4As shown, the difference between this and Embodiment 1 lies only in the structure of the switching bucket. Specifically, the switching bucket is a swing bucket 6 capable of lateral swinging. The swing bucket 6 has two vertically penetrating connecting channels arranged laterally, and the lateral arrangement direction of the two connecting channels is the same as the lateral arrangement direction of the first and second feeding hoppers. That is, the two connecting channels are arranged left and right accordingly. The lateral swinging direction of the swing bucket 6 is the same as the lateral arrangement direction of the two connecting channels, that is, the swing bucket swings left and right. A swing driving device is installed on the frame to drive the swing bucket to swing along the lateral arrangement direction of the two connecting channels. The swing driving device is the aforementioned rotation switching driving device.
[0033] Preferably, the swing bucket 6 has a front side plate, a rear side plate, and a partition plate between the front side plate and the rear side plate. The partition plate, the left side of the front side plate, and the left side of the rear side plate form a left-side open and vertically connected channel, which is one of its connecting channels. The partition plate, the right side of the front side plate, and the right side of the rear side plate form a right-side open and vertically connected channel, which is another connecting channel. The front side plate is rotatably mounted on the frame via a rotating shaft 7. A swing drive device is installed on the outside of the rear side plate. To facilitate the installation of the rotating shaft 7 and the swing drive device, a separate upright frame 8 located behind the swing bucket 6 can be locked onto the frame.
[0034] This oscillating drive device has a drive motor 91 and a swing arm 92. The drive motor 91 is horizontally arranged in the front-to-back direction, and the swing arm 92 is vertical. The output shaft of the drive motor 91 drives the lower end of the swing arm 92 to be fixedly connected together. The upper end of the swing arm 92 is provided with a horizontal bar 93, which is fixedly connected to the swing bucket 6 in the front-to-back direction. In application, the drive motor 91 is started, and the swing arm 92 swings left and right. The swing of the swing arm 92 drives the swing bucket 6 to swing through the horizontal bar.
[0035] When applying, such as Figure 5 As shown, the swing bucket 6 swings to the left, and the right-side channel of the swing bucket 6 is inclined downward from left to right, and is located below and to the left of the output end of the metering hopper 1. At this time, the material output from the metering hopper 1 is guided downward through the right-side channel to the lower hopper body on the right side, and is output from the lower hopper body on the right side; similarly, as... Figure 6 As shown, the swing bucket 6 swings to the right, and the left channel of the swing bucket 6 is inclined downward from right to left and is located below the right side of the output end of the quantitative hopper 1. At this time, the material output from the quantitative hopper 1 is guided downward through the right channel to the lower bucket body on the left side and output from the lower bucket body on the left side.
[0036] In this embodiment, the drive motor can also be located directly behind the rotating shaft 7, and the output shaft of the drive motor is fixedly connected to the rear end of the rotating shaft 7 with its front facing direction, so that there is no need to set up a swing arm.
[0037] In this implementation, the installation position of the rotating shaft is not limited to the lower part of the switching bucket, such as... Figure 7 , 8 As shown, the rotating shaft can also be set at the top of the swing bucket.
[0038] In this invention, the rotary drive device for driving the swing bucket to rotate circumferentially or swing left and right is not limited to the description in this embodiment, and any driving method can be replaced.
[0039] The product form of this utility model is not limited to the illustrations and embodiments in this case. Any appropriate changes or modifications made to it based on similar ideas should be considered as not departing from the patent scope of this utility model.
