Description

Technical Field

[0001] This utility model relates to the field of packaging, and in particular to a switching-type over-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 switching 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 switching-type overload sorting structure includes a frame and a quantitative hopper and a discharge hopper mounted on the frame. The quantitative hopper has a quantitative conveying channel, and the discharge hopper has a discharge channel. The input end of the discharge channel is connected to the input end of the quantitative conveying channel. The discharge hopper has a receiving channel connected to the quantitative conveying channel and two diversion channels whose input ends are connected to the receiving channel. The receiving channel and the two diversion channels constitute the discharge channel. The receiving channel is provided with a rotatable switching channel that enables the quantitative conveying channel to switch between the two diversion channels. The frame is provided with a rotation drive device for controlling the rotation of the switching channel.

[0007] The aforementioned hopper has an upper channel that runs vertically through it and two lower channels that are located below the upper channel and arranged horizontally. The output end of the quantitative conveying channel is within the range of the upper channel. The upper channel is the receiving channel, and the lower channels are the diversion channels.

[0008] The aforementioned hopper has an upper hopper body and two lower hopper bodies. Both the upper and lower hopper bodies are hollow hopper bodies that run vertically through each other. The two lower hopper bodies are arranged horizontally side by side below the upper hopper body. The upper ends of the two lower hopper bodies fall into the upper hopper body. The hollow cavity of the upper hopper body is the receiving channel, and the hollow cavity of the lower hopper body is the diversion channel.

[0009] The aforementioned diversion channel is a downward-sloping channel.

[0010] The two inclined channels may be inclined in the same or different directions.

[0011] An inner hopper that is vertically connected and circumferentially rotatable is erected in the aforementioned receiving channel. The hollow cavity of the inner hopper is the switching channel. The output end of the quantitative conveying channel falls into the upper range of the inner hopper. The lower end of the inner hopper is located below the two diversion channels. A rotation drive device is installed on the aforementioned frame to drive the inner hopper to rotate circumferentially and to switch the lower end of the inner hopper to the range of the two diversion channels.

[0012] The aforementioned inner hopper is a conical hopper that is larger at the top and smaller at the bottom. An installation plate is installed on the outer wall of the aforementioned inner hopper, and the aforementioned rotating drive device that drives the installation plate to rotate is installed on the aforementioned frame.

[0013] The aforementioned receiving channel is equipped with an internal bucket that is vertically mounted and can swing laterally. The internal bucket has two vertically penetrating connecting channels. The two connecting channels are arranged laterally and constitute the switching channel. The lateral arrangement direction of the two connecting channels is the same as the arrangement direction of the upper end of the two diversion channels. The aforementioned frame is equipped with a swaying drive device that drives the internal bucket to sway along the lateral arrangement direction of the two connecting channels.

[0014] With the lateral arrangement of the two connecting channels as the left-right direction, the aforementioned inner hopper 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 oscillation drive device is installed on the outside of the rear side plate.

[0015] The aforementioned oscillation drive device has a drive motor and an oscillating rod. The oscillating rod is upright, and the output shaft of the drive motor is connected to the first end of the oscillating rod in a way that drives it to rotate. The second end of the oscillating rod is connected to the second end of the oscillating rod in a way that drives the inner bucket to swing left and right.

[0016] With the above technical solution, the present invention provides a switching-type over-sorting structure, which is installed between the weighing mechanism and the packaging mechanism. One diversion channel is aligned with the packaging mechanism as the precision channel, and the other diversion channel is aligned with the collection bin as the non-precision channel. The initial state is that the switching channel and the precision channel are connected. 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 channel and the precision channel to the packaging mechanism for packaging. If the material output from the quantitative hopper exceeds the required packaging quantity, the rotation drive device is activated, causing the switching channel to rotate and align with the non-precision channel. The material in the quantitative hopper is then output through the switching channel and the non-precision channel to the collection bin for collection and repackaging. Compared with existing technologies, by utilizing the rotation of the switching channel and the switching and conduction of the two diversion channels, 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 switching-type overload sorting structure, as shown in Embodiment 1. Figure 1-2 As shown, the machine includes a frame (not shown in the figure) and a quantitative hopper 1 and a discharge hopper mounted on the frame. The quantitative hopper 1 has a quantitative conveying channel. This quantitative hopper is an existing weighing or counting hopper, a well-known product, and will not be described again here. The discharge hopper 2 has a discharge channel. The input end of the discharge channel is connected to the input end of the quantitative conveying channel. As shown in the figure, the quantitative hopper is located above the discharge hopper, but it is not limited to the vertical relationship, as long as it can receive the material. The discharge hopper 2 has a receiving channel that connects to the quantitative conveying channel and two diversion channels whose input ends are connected to the receiving channel. The receiving channel and the two diversion channels constitute the discharge channel. The receiving channel is equipped with a rotating switching channel that can switch the quantitative conveying channel and the two diversion channels. The frame is equipped with a rotation drive device to control the rotation of the switching channel.

[0026] Preferably, the hopper 2 has an upper channel that runs vertically through it and two lower channels that are located below the upper channel and arranged horizontally. The output end of the quantitative conveying channel is within the range of the upper channel. The upper channel is the receiving channel, and the lower channel is the diversion channel. That is, the upper channel is a square channel, and the lower end of the upper channel is provided with two independent, horizontally parallel, vertically through channels. These through channels are the diversion channels.

[0027] In this invention, for processing by the feeding hopper 2, the feeding hopper 2 has an upper hopper body 21 and two lower hopper bodies 22. Both the upper hopper body 21 and the lower hopper bodies 22 are hollow hopper bodies that extend vertically. The upper hopper body 21 is a square frame with a front upright plate, a left upright plate, and a right upright plate. The hollow cavity of the upper hopper body 21 serves as the receiving channel. The two lower hopper bodies 22 are arranged horizontally side by side below the upper hopper body 21, and the upper ends of both lower hopper bodies 22 fall into the upper hopper body 22. The hollow cavity of the lower hopper body 22 serves as the diversion channel. The diversion channel is preferably a downward-sloping inclined channel. The two inclined channels have different inclination directions. Specifically, taking the left-right arrangement of the two lower hopper bodies 22 as an example, the left lower hopper body consists of an upper top plate, a lower bottom plate, a left side plate, and a right side plate. The upper hopper is formed by two plates. The top plate is located outside the front of the upper hopper and slopes downwards from back to front, connecting to the front upright plate. The bottom plate is located inside the rear of the upper hopper and slopes downwards from back to front. The left side plate is connected to the left upright plate, and the right side plate is located within the middle space of the upper hopper. The right lower hopper is composed of a front side plate, a rear side plate, a left inclined plate, and a right inclined plate. The front and rear side plates are vertically arranged facing each other, with the front side plate connected to the front upright plate. The left and right inclined plates slope downwards from left to right. The left inclined plate is located within the middle space of the upper hopper and aligns with the right side plate, with its upper end fitting tightly against the upper end of the right side plate. The right inclined plate is located outside the right side of the upper hopper and connects to the right upright plate. The inclined channel within the lower hopper facilitates material output. In this invention, the inclination direction of the two lower hoppers can also be the same, i.e., both tilting forward or backward. Furthermore, the different inclination directions of the two lower hoppers are not limited to the direction in this embodiment.

[0028] In this invention, regarding the setting of the switching channel, it is preferable that an inner bucket 3, which is vertically connected and circumferentially rotatable, is erected in the receiving channel. The hollow cavity of the inner bucket 3 serves as the switching channel. The output end of the quantitative conveying channel falls into the upper range of the inner bucket 3, and the lower end of the inner bucket 3 is located below the two diversion channels. A rotation drive device is installed on the frame to drive the inner bucket to rotate circumferentially, and the lower end of the inner bucket is switched to be within the range of the two diversion channels.

[0029] Preferably, the inner bucket 3 is a conical bucket with a larger upper end and a smaller lower end. The lower left part of the inner bucket 3 is positioned above the lower bucket on the left side, and the lower right part is positioned above the lower bucket on the right side.

[0030] An mounting plate 4 is installed on the outer wall of the machine. A rotary drive device, which drives the mounting plate 4 to rotate, is mounted on the frame. This rotary drive device can be a drive motor. Specifically, the mounting plate 4 has a horizontal section, and a vertically mounted drive motor is installed below the horizontal section on the frame. The output shaft of the drive motor is connected to the horizontal section. In this way, the drive motor drives the mounting plate to rotate, and the entire inner hopper 3 rotates circumferentially accordingly. Alternatively, the drive motor can be positioned between the right side plate and the left inclined plate, with a through-spacing between the right side plate and the left inclined plate for the output shaft of the drive motor to pass through.

[0031] This utility model discloses a switching overload sorting structure, which is installed between a weighing mechanism and a packaging mechanism. One lower hopper is aligned with the packaging mechanism and serves as the discharge hopper. The other lower hopper is aligned with the collection bin and serves as the overload hopper. The discharge hopper is connected to the inner hopper, and the overload hopper and the inner hopper are initially misaligned. In application, if the material output from the quantitative hopper 1 meets the packaging quantity required by the packaging mechanism, the material is directly output from the quantitative hopper 2, passes through the inner hopper 3 and the discharge hopper, and is packaged inside the packaging mechanism. If the material output from the quantitative hopper 2 exceeds the required packaging quantity, the drive device is activated, and the inner hopper 3 rotates. The axis of the inner hopper 3 is not on the same straight line as the axis of the drive motor. When the inner hopper 3 rotates, its lower end can rotate from the range of the discharge hopper to the range of the overload hopper. The material in the quantitative hopper 1 passes through the inner hopper 3 and the overload hopper and is collected in the collection bin for repackaging. Compared with existing technologies, by using the rotation of the inner hopper 3 to switch and connect with the two lower hoppers respectively, overweight and over-quantity 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 problem of high packaging costs and low efficiency for manufacturers caused by the inaccurate weighing of traditional weighing mechanisms. Moreover, overweight and over-quantity materials in the quantitative hopper are directly recycled to the weighing mechanism for re-weighing and packaging, making the operation convenient.

[0032] This utility model provides a switching-type overload sorting structure, embodiment two, as follows: Figure 3 As shown,

[0033] The difference in one embodiment lies only in the structure of the inner bucket. Specifically, the receiving channel is provided with an inner bucket 4 that can swing laterally. The inner bucket 4 has two vertically penetrating connecting channels. The two connecting channels are arranged laterally and constitute the switching channel. The lateral arrangement direction of the two connecting channels is the same as the arrangement direction of the upper end of the two diversion channels. A swaying drive device is installed on the frame to drive the inner bucket to sway along the lateral arrangement direction of the two connecting channels.

[0034] Specifically, with the horizontal arrangement of the two connecting channels as the left and right directions, the inner bucket body 4 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 (i.e., the front body of the upper bucket body) via a rotating shaft. A swing drive device is installed on the outside of the rear side plate.

[0035] This oscillation drive device has a drive motor 5 and an oscillating arm 6. The drive motor 5 is horizontally positioned along the front-to-back direction, while the oscillating arm 6 is vertical. The output shaft of the drive motor 5 drives the lower end of the oscillating arm 6, which is fixedly connected to it. A horizontal bar is provided on the lower end of the oscillating arm 6, which is fixedly connected to the inner hopper 3. In operation, the drive motor 5 is activated, and the oscillating arm 6 swings left and right. The swing of the oscillating arm 6 drives the inner hopper 4 to swing via the horizontal bar.

[0036] When applying, such as Figure 4 , 5 As shown, the inner hopper 4 tilts to the left, and the right channel of the inner hopper 4 is inclined downward from left to right and is located below the left 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 hopper body on the right side and output from the lower hopper body on the right side. At the same time, the inner hopper 4 tilts to the right, and the left channel of the inner hopper 4 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 hopper body on the left side and output from the lower hopper body on the left side.

[0037] In this embodiment, in order to make the swing of the inner bucket 3 smoother, a horizontal rotating shaft can be installed at the lower part of the inner bucket 3, which is rotated and fitted with the upper bucket.

[0038] In this embodiment, the drive motor can also be located directly behind the rotating shaft, and the output shaft of the drive motor is fixedly connected to the rear end of the rotating shaft with its front facing direction, thus eliminating the need for a swing arm.

[0039] In this implementation, the installation position of the rotating shaft is not limited to the lower part of the switching bucket, such as... Figure 6 , 7 As shown, the pivot can also be located on the upper part of the inner hopper.

[0040] In this invention, the rotary drive device for driving the inner bucket to rotate or swing in the circumferential direction is not limited to the description in this embodiment, and any drive method can be used instead.

[0041] 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.
