Abstract
Description
Technical Field
[0001] This utility model belongs to the field of packaging material screening equipment, and in particular relates to a packaging material sorting device. Background Technology
[0002] Sorting scales are commonly used for weight grading and selection, especially in the pharmaceutical and food industries, where they are widely applied. After products are packaged and sealed, they are sorted by weight, and packages that do not meet the weight requirements are removed to ensure the consistency of product manufacturing specifications.
[0003] Currently, a collision prevention mechanism and a rejection device for weighing bottled products are disclosed in the patent application number 2022225556312. The device uses a support plate to place unqualified packaging materials, but due to its opening, qualified packaging materials can easily fall into it during transportation. In addition, its height is small, and the applicable packaging material size is limited, which is not conducive to production. Utility Model Content
[0004] In view of this, the present invention aims to overcome the shortcomings of the above-mentioned problems in the prior art and proposes a packaging material sorting device.
[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0006] A packaging sorting device includes a sorting scale body. The two side plates of the conveyor belt of the sorting scale body are a first side plate and a second side plate, respectively. A push plate is provided on the first side plate near the output end of the conveyor belt. A collection frame is fixedly connected to the outer side of the second side plate corresponding to the push plate. The push plate can move along the width direction of the upper surface of the sorting scale body. A top rod is fixedly connected on the side of the push plate facing the second side plate, located above the conveyor belt of the sorting scale body. A U-shaped groove is opened on the second side plate. An opening and closing limiting plate is provided in the U-shaped groove. One end of the limiting plate can rotate along one side of the U-shaped groove, and the other end abuts against the other side of the U-shaped groove. The top rod can push open the limiting plate.
[0007] Furthermore, an inverted L-shaped mounting plate is fixed to the outer side of the first side plate, and a telescopic unit is fixed to the mounting plate. The push plate is fixed to the end of the guide rod of the telescopic unit.
[0008] Furthermore, a push rod is screwed onto the front side of the push plate near the upper end.
[0009] Furthermore, the number of push plates is one.
[0010] Furthermore, there are multiple push plates, which are stacked vertically. The bottom push plate is fixed to the end of the guide rod of the telescopic unit, and the top rod is screwed to the top push plate. In two adjacent push plates, the top of the lower push plate is provided with multiple first positioning holes, and the bottom of the upper push plate is fixed with a first positioning post corresponding to the first positioning hole. The first positioning post is inserted into the first positioning hole. There are multiple first positioning blocks between the rear side walls of two adjacent push plates. Each first positioning block is fixed to the two push plates by screws.
[0011] There are one or more limiting plates. When there are multiple limiting plates, they are stacked and fixed together longitudinally. The horizontal plane where the axis of the push rod is located intersects with the limiting plate to ensure that the push rod can hit the limiting plate during movement.
[0012] Furthermore, one side of the limiting plate is connected to one side of the U-shaped groove via a damping hinge, and the other side abuts against the other side of the U-shaped groove.
[0013] Furthermore, an iron sheet is embedded and fixed at the free end of the limiting plate, and a magnet is embedded and fixed at the corresponding position of the iron sheet on the U-shaped groove. When the limiting plate is in the closed state in the U-shaped groove, the magnet and the iron sheet are magnetically attracted together.
[0014] Furthermore, the outer side of the collection frame is provided with a U-shaped mounting groove, and symmetrical C-shaped limiting grooves are provided on both sides of the mounting groove. A plug plate is inserted into the mounting groove, and the two sides of the plug plate are provided with integrally formed limiting edges corresponding to the limiting grooves. The limiting edges are inserted into the limiting grooves.
[0015] Furthermore, a buffer strip is provided on the side of the push plate facing the limiting plate.
[0016] Compared with the prior art, this utility model has the following advantages:
[0017] In use, the packaging sorting device of this utility model transports the packaging on the conveyor belt of the sorting scale body. After being weighed by the sorting scale body, the packaging that does not meet the weight standard is pushed into the collection box by the push plate. During this process, the push plate is controlled to push forward, and the limit plate is opened by the top rod. The push plate pushes the unqualified packaging into the collection box. Then the push plate is reset, the top rod moves away from the limit plate, and the limit plate is closed. The device has a simple structure and is easy to operate. It effectively reduces the erroneous rejection of qualified packaging without affecting the continued transport of qualified packaging. It is also suitable for sorting packaging of different heights and sizes, avoiding the situation where when sorting taller packaging, only the lower part of the packaging is pushed, and the packaging is prone to tilting towards the push plate and falling off the push plate side.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0027] As shown in the figure, a packaging sorting device includes a sorting scale body 1. The two side plates of the conveyor belt of the sorting scale body 1 are a first side plate 101 and a second side plate 102, respectively. A push plate 2 is provided on the first side plate 101 near the output end of the conveyor belt. A collection frame 5 is fixedly connected to the outer side of the second side plate 102 corresponding to the push plate 2. The push plate 2 can move along the width direction of the upper surface of the sorting scale body 1. A top rod 3 located above the conveyor belt of the sorting scale body 1 is fixedly connected on the side of the push plate 2 facing the second side plate 102. A U-shaped groove 104 is opened on the second side plate 102. A limit plate 4 that can be opened and closed is provided in the U-shaped groove 104. One end of the limit plate 4 can rotate along one side of the U-shaped groove 104, and the other end abuts against the other side of the U-shaped groove 104. The top rod 3 can push open the limit plate 4. In this embodiment, the packaged goods are transported on the conveyor belt of the sorting scale body 1. After being weighed by the sorting scale body 1, the packaged goods that do not meet the weight standard are pushed into the collection box 5 by the push plate 2. During this process, the push plate 2 is controlled to push forward, and the limiting plate 4 is pushed open by the top rod 3. The push plate 2 pushes the unqualified packaged goods into the collection box 5. Then the push plate 2 is reset, the top rod 3 moves away from the limiting plate 4, and the limiting plate 4 is closed.
[0028] An inverted L-shaped mounting plate 9 is fixedly connected to the outer side of the first side plate 101. A telescopic unit 8 is fixedly connected to the mounting plate 9, and a push plate 2 is fixedly connected to the end of the guide rod of the telescopic unit 8. In this embodiment, a groove 103 is provided on the first side plate 101, and the bottom of the groove 103 is flush with the upper surface of the conveyor belt of the sorting scale body 1. When the guide rod of the telescopic unit 8 is in its shortest stroke, the push plate 2 is located in the groove 103, ensuring that the packaged goods will not slip off the groove 103. In this embodiment, the telescopic unit 8 is an electric cylinder.
[0029] The push plate 2 is screwed to the top rod 3 near the upper end.
[0030] The number of push plates 2 is one.
[0031] There are multiple push plates 2, which are stacked longitudinally. The bottom push plate 2 is fixed to the end of the guide rod of the telescopic unit 8. The top rod 3 is screwed onto the top push plate 2. In two adjacent push plates 2, the top of the lower push plate 2 is provided with multiple first positioning holes 201. The bottom of the upper push plate 2 is fixed with a first positioning post corresponding to the first positioning hole 201. The first positioning post is inserted into the first positioning hole 201. There are multiple first positioning blocks 10 between the rear side walls of two adjacent push plates 2. Each first positioning block 10 is fixed to the two push plates 2 by screws. There are one or more limit plates 4. When there are multiple limit plates 4, the multiple limit plates 4 are stacked and fixed together longitudinally. The horizontal plane where the axis of the top rod 3 is located intersects with the limit plate 4 to ensure that the top rod 3 can hit the limit plate 4 during the movement. In this embodiment, when there are multiple limiting plates 4, in two adjacent limiting plates 4, the top of the lower limiting plate 4 is provided with multiple second positioning holes 401, and the bottom of the upper limiting plate 4 is fixedly connected to the second positioning hole 401. The second positioning hole is inserted into the second positioning hole 401, and multiple second positioning blocks 11 are provided between the rear side walls of two adjacent limiting plates 4. Each second positioning block 11 is fixed to the two limiting plates 4 by screws.
[0032] One side of the limiting plate 4 is connected to one side of the U-shaped groove 104 via a damping hinge 7, allowing the limiting plate 4 to rotate and reset along that side. The other side abuts against the other side of the U-shaped groove 104. In this embodiment, when there are multiple limiting plates 4, the damping hinge 7 can be installed on the bottommost limiting plate 4.
[0033] An iron sheet is embedded and fixed at the free end of the limiting plate 4, and a magnet is embedded and fixed at the corresponding position of the iron sheet on the U-shaped groove 104. When the limiting plate 4 is in the closed state in the U-shaped groove 104, the magnet and the iron sheet are magnetically attracted together, which further improves the fixation of the limiting plate 4 in the U-shaped groove 104 and prevents the limiting plate 4 from being accidentally opened, causing qualified packaging materials to fall into the collection box 5.
[0034] In this embodiment, when there are multiple limiting plates 4, a damping hinge 7 can be installed on the bottommost limiting plate 4, and an iron plate can be installed on the free end of the bottommost limiting plate 4.
[0035] like Figure 2 As shown, there are two limit plates and two push plates.
[0036] The outer side of the collection frame 5 is provided with a U-shaped mounting groove 501. On the two side walls of the mounting groove 501, there are symmetrical C-shaped limiting grooves 502. A plug-in plate 6 is inserted into the mounting groove 501, and the two sides of the plug-in plate 6 are provided with integrally formed limiting edges 601 corresponding to the limiting grooves 502. The limiting edges 601 are inserted into the limiting grooves 502. When it is necessary to remove the unqualified packaging from the collection frame 5, a transfer frame or transfer vehicle is placed under the collection frame 5, and the plug-in plate 6 is lifted up. The packaging slides out from the mounting groove 501 and falls into the transfer frame or transfer vehicle. Of course, the packaging can also be removed manually from the mounting groove 501. This method of removing the packaging saves time and effort.
[0037] A buffer strip 12 is provided on the side of the push plate 2 facing the limiting plate 4. In this embodiment, the buffer strip 12 is made of rubber and is adhered to the push plate 2. When it is applied to the packaged goods, it plays a protective and buffering role to avoid damaging the packaged goods.
[0038] The working process of this embodiment is as follows:
[0039] The number of push plates 2 and limit plates 4 required is determined based on the height of the packaged goods placed on the conveyor belt, ensuring that the height of the push rod 3 does not affect the conveying of qualified packaged goods.
[0040] The packaged goods are transported on the conveyor belt of the sorting scale body 1. After being weighed by the sorting scale body 1, the packaged goods that do not meet the weight standard are pushed into the collection frame 5 by the push plate 2. During this process, the push plate 2 is pushed forward by the telescopic unit 8, and the limit plate 4 is pushed open by the top rod 3. The push plate 2 pushes the unqualified packaged goods into the collection frame 5. Then the push plate 2 is reset, the top rod 3 moves the limit plate 4 away, and the limit plate 4 is closed under the action of the damping hinge 7.
[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
