Description

Technical Field

[0001] This utility model relates to the field of packaging unpacking machine technology, specifically a waste bag collector for packaging unpacking machines. Background Technology

[0002] In some production processes, it is necessary to unseal packaging bags before feeding raw materials into reaction equipment. Currently, raw material packaging is unsealed using a packaging unpacking machine, and the unsealed packaging bags become waste bags. Existing waste bag disposal methods involve collecting the waste bags using a waste bag collector from a packaging unpacking machine.

[0003] For example, Chinese patent application number "201621273068.8" discloses a "waste bag conveying device for unpacking machine," which includes a waste bag conveying mechanism. The waste bag conveying mechanism has a waste bag inlet and an outlet. The outlet is connected to an outlet cylinder, and the outlet cylinder has a slidable pressure ring. The pressure ring presses the cylindrical bag body used for collecting waste bags against the outer wall of the outlet cylinder at its free end. The waste bag conveying mechanism includes a shaftless conveying screw, a housing, and a drive motor. The inlet is located at the top of the housing, and the outlet is located on one side of the housing. The shaftless conveying screw is located in a cavity inside the housing and extends into the outlet. The conveying screw can automatically convey waste bags to the collection bag. When the collection bag is full, it will not fall off the outlet cylinder due to the tightening effect of the pressure ring. Although it can collect waste bags, during the rotation of the shaftless conveying screw, waste bags are easily entangled on the screw blades, affecting subsequent waste bag collection.

[0004] In view of this, there is an urgent need for a waste bag collector for unpacking machines. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A waste bag collector for a packaging unpacking machine includes a collection housing and a shafted screw. A bag outlet channel is provided on one side of the collection housing, and the bag outlet channel communicates with the inner cavity of the collection housing. The top of the collection housing is open.

[0008] The axial spiral is disposed in the inner cavity of the collection housing. One end of the axial spiral is rotatably mounted on the side of the collection housing away from the bag outlet channel, and the other end points towards the bag outlet channel. The collection housing is provided with a drive assembly for driving the axial spiral to rotate.

[0009] A bag-scraping strip is provided on one side of the inner cavity of the collection shell, and the bag-scraping strip is arranged parallel to the shafted spiral.

[0010] Its further feature is that,

[0011] The scraper strip is positioned near the opening.

[0012] The top surface of the shafted spiral self-scraping bag strip rotates towards the bottom surface of the bag scraping strip.

[0013] An L-shaped plate is provided inside the collection housing. The vertical part of the L-shaped plate is fixed to one side of the collection housing, and the bag scraper is installed on the top surface of the horizontal part of the L-shaped plate by bolts.

[0014] The inner cavity of the collecting shell is a semi-circular shape with the bottom of the cross-section facing upwards at the axial direction of the spiral.

[0015] The bag outlet channel includes a transition cylinder and an outlet cylinder arranged sequentially from one end of the collection housing. The opening of the transition cylinder near the collection housing is adapted to the inner cavity of the collection housing, and the other end is a circular opening. The outlet cylinder is cylindrical.

[0016] The drive component is a geared motor, which is installed on the outside of the collection housing, and the shafted screw is coaxially connected to the output end of the geared motor.

[0017] The above-described structure of this utility model can achieve the following beneficial effects:

[0018] By inserting waste bags into the waste bag collection housing, the drive assembly drives the shafted screw to rotate. The rotation of the blades pushes the packaging bag towards the bag outlet channel. When the shafted screw rotates, the outer ring surface passes the bag scraper, and the packaging bag wrapped around it is scraped off (the outer ring surface of the shafted screw will not retain the packaging bag), preventing the bag from getting tangled on the spiral blades of the shafted screw and affecting subsequent collection work.

[0022] In the diagram: 1. Collection shell; 2. Shafted spiral; 3. Bag outlet channel; 31. Transition cylinder; 32. Bag outlet cylinder; 4. Bag scraper strip; 5. L-shaped plate; 6. Gear motor. Detailed Implementation

[0023] Example 1, Reference Figure 1-3The waste bag collector of the unpacking machine shown includes a collection shell 1 and a shafted spiral 2 (composed of a central shaft and spiral blades extending from one end of the central shaft to the other end). A bag outlet channel 3 is provided on one side of the collection shell 1, and the bag outlet channel 3 communicates with the inner cavity of the collection shell 1. The top of the collection shell 1 is open.

[0024] A shafted screw 2 is disposed in the inner cavity of the collection housing 1. One end of the shafted screw 2 is rotatably mounted on the side of the collection housing 1 away from the bag outlet channel 3, and the other end points towards the bag outlet channel 3. A drive assembly for driving the shafted screw 2 to rotate is provided on the collection housing 1. The drive assembly is a geared motor 6. The geared motor 6 is mounted on the outside of the collection housing 1. The shafted screw 2 is coaxially connected to the output end of the geared motor 6.

[0025] A bag scraping strip 4 is provided on one side of the inner cavity of the collection housing 1, and the bag scraping strip 4 is arranged parallel to the shafted spiral 2.

[0026] Based on the above structure, by putting the waste bag into the waste bag collection housing 1, the drive assembly drives the shafted screw 2 to rotate. The rotation of the blades pushes the packaging bag to move towards the bag outlet channel 3. When the shafted screw 2 rotates, when its outer ring surface passes the bag scraping strip 4, the packaging bag wrapped on it is scraped off (the outer ring surface of the shafted screw 2 will not retain the packaging bag), preventing the bag from getting tangled on the spiral blades of the shafted screw 2 and affecting the subsequent collection work.

[0027] Among them, the scraper strip 4 is set near the opening.

[0028] In actual use, the scraper strip 4 is prone to wear during operation. By setting the scraper strip 4 close to the opening, it is easier to replace and maintain it later.

[0029] Among them, the shafted spiral 2 rotates from the top surface of the scraping bag strip 4 towards the bottom surface of the scraping bag strip 4.

[0030] In actual use, by rotating the top surface of the self-scraping bag strip 4 of the shafted spiral 2 towards the bottom surface of the self-scraping bag strip 4, the waste bags wrapped around the outside of the shafted spiral 2 are scraped upwards, making it easy for staff to observe from the opening at any time.

[0031] The collection housing 1 is equipped with an L-shaped plate 5. The vertical part of the L-shaped plate 5 is fixed to one side of the collection housing 1, and the bag scraping strip 4 is installed on the top surface of the horizontal part of the L-shaped plate 5 by bolts.

[0032] In actual use, the scraper strip 4 is installed on the top surface of the horizontal part of the L-shaped plate 5 by bolts, which makes it easy to install and remove the scraper strip 4.

[0033] The inner cavity of the collecting shell 1 is a semi-circular shape with the bottom of the cross section of the shafted spiral 2 facing upwards.

[0034] In actual use, by setting the bottom of the inner cavity of the collection housing 1 to a shape that matches the shafted spiral 2, the waste bag will not remain in the collection housing 1.

[0035] The bag outlet channel 3 includes a transition cylinder 31 and a bag outlet cylinder 32 arranged sequentially from one end of the collection housing 1. The opening of the transition cylinder 31 near the collection housing 1 is adapted to the inner cavity of the collection housing 1, and the other end is a circular opening. The bag outlet cylinder 32 is cylindrical.

[0036] In actual use, the waste bag becomes round after passing through the bag outlet channel 3 (the top of one end of the transition cylinder 31 is square), which makes the bag produce a better compression effect, and the waste bag will not block the connection between the bag outlet channel 3 and the collection shell 1.

[0037] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
