Description

Technical Field

[0001] This utility model relates to the field of edge-melting machine technology, specifically to a waste collection device for a film edge-melting machine. Background Technology

[0002] A film edge-sealing machine is a device that uses an electrically heated hot melt blade to melt and bond the film it passes through. It is typically used to bond two layers of film that have been folded by a folding machine and are then separated from each other.

[0003] During this process, the side of the hot melt knife away from the film bending will usually separate a film of about 3 cm in width due to hot melting, in order to ensure the stability of the equipment in melting and bonding the film. In order to separate and collect these film wastes, an existing patent published with publication number CN215882773U is a bag making edge melting machine, which uses negative pressure blowing to guide the film wastes through the guide channel to the collection box.

[0004] While this method effectively separates film waste from the hot melt knife, the film waste is relatively narrow and long, and its bending state when blown into the collection box is quite complex. As a result, the collection box is easily filled with short-length film waste, causing the film waste to quickly stop being injected into the guide channel. Workers need to clean the waste in the collection box regularly, and cleaning such accumulated waste from the collection box is also quite troublesome.

[0005] To address the aforementioned issues, an alternative waste collection device for edge melting machines has been proposed. Utility Model Content

[0006] The purpose of this invention is to solve the problems in the prior art by proposing a waste collection device for a film edge melting machine.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a waste collection device for a film edge melting machine, comprising:

[0008] The rack is placed on the ground;

[0009] A cutter, mounted on a frame, cuts waste material from one side of the material.

[0010] A pipe is mounted on the frame, with one end of the pipe facing the waste material;

[0011] A guide component is fixedly installed inside a pipe, and the guide component includes a spiral portion spirally arranged along the inner wall of the pipe;

[0012] An air knife, mounted on a frame, is used to blow waste material separated from the surface of the material into a pipe;

[0013] A sleeve rod is installed at the pipe opening on the side away from the air knife. The side of the sleeve rod away from the pipe is formed into a hook-shaped structure to allow material passing through the guide swivel to wrap around and temporarily store on the sleeve rod.

[0014] The present invention is further configured such that: the end of the sleeve rod away from the pipe is provided with a through hole through which waste material can pass, and the outer wall of the sleeve rod is fixedly provided with a plurality of winding parts for positioning the waste material after it passes through the through hole.

[0015] The present invention is further configured such that: the perforation has a constricted structure from the outside to the inside, and the periphery of the perforation is formed with a rounded corner structure.

[0016] The present invention is further configured such that the cross-section of the winding portion has a U-shaped structure.

[0017] The present invention is further configured such that: the sleeve is embedded in the pipe and rotatably connected to the guide, and the axis of the sleeve is close to that of the pipe.

[0018] The present invention is further configured such that: the guide includes a cutting part fixedly disposed near the side of the air knife, the cutting part having a cutting edge facing the waste material forming, and the air blowing port of the air knife being disposed parallel to the length direction of the cutting edge.

[0019] The present invention is further configured to include several support rods and a sliding seat. The support rods are mounted on the frame, and the sliding seat can slide along the support rods. The cutter and the air knife are both fixedly mounted on the sliding seat.

[0020] The present invention is further configured such that: the pipe and the sliding seat are detachably connected by a connector, and the connector can position the angle between the pipe end face near the waste material end and the material surface, so as to adjust the position of the pipe to accommodate the waste material and align the position of the waste material separated by the cutter.

[0021] In summary, this utility model has the following beneficial effects: compared with the prior art, this application can effectively reduce the frequency of emptying the collected waste, and at the same time, it is simple and convenient to clean the waste from the sleeve rod.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] A waste collection device for a film edge melting machine, such as Figures 1 to 4 As shown, the device includes a frame 1 placed on the ground. Several motor-driven conveyor rollers are rotatably mounted on the frame 1 for conveying materials. The frame 1 is equipped with two support rods 3 and a sliding seat 2. Each support rod 3 includes a lead screw. The sliding seat 2 is equipped with a cutter 4 that can cut waste material from one side of the material. As the sliding seat 2 slides along the support rods 3, the position of the cutter 4 can be adjusted to thermally cut the surface of the material. The cutter 4 can also slide along the sliding seat 2 closer to or further away from the material surface. See the attached diagram for the specific structure. Figure 1 However, since it is irrelevant to the implementation of this plan, it will not be discussed in detail here;

[0029] The frame 1 is equipped with a pipe 6 with one side opening facing the waste material. A guide 8 is fixedly installed inside the pipe 6. The guide 8 includes a spiral guide part 81 spirally arranged along the inner wall of the pipe 6. In this application, the pipe 6 is fixedly bonded to a straight pipe by a U-shaped tube. The spiral guide part 81 is fixedly bonded inside the spiral guide part 81. An air knife 5 is provided on the frame 1. The air knife 5 is used to blow the waste material separated from the surface of the material into the pipe 6. The waste material is blown by the air from the air knife 5 and continuously conveyed by the conveying roller. The material continuously forms a spiral shape along the guide part 81 and is finally carried out from the pipe 6. A spiral structure will be formed. In order to maintain this structure outside the pipe 6, a sleeve rod 7 is installed on the pipe opening away from the air knife 5. The side of the sleeve rod 7 away from the pipe 6 is formed into a hook-shaped structure to allow the material passing through the guide 81 to be wrapped around and temporarily stored on the sleeve rod 7. In this specific embodiment, in order to make it easier to use the device, both the cutter 4 and the air knife 5 are fixedly set on the sliding seat 2. The pipe 6 is connected to the sliding seat 2. In order to make it easier for the waste material to be put on the sleeve rod 7, the sleeve rod 7 is embedded in the pipe 6 and rotatably connected to the guide 8. The axis of the sleeve rod 7 and the pipe 6 are coincident.

[0030] Usage: The waste material is gradually accumulated on the sleeve rod 7 in a spiral shape. It is compressed by the weight of the waste material itself and is also affected by the unfolding property of the spiral structure. The sleeve rod 7 can accommodate a relatively long length of waste material.

[0031] Meanwhile, when there is a lot of waste, after cutting the upper part of the waste, pull the end of the waste along the sleeve 7 and insert it into the middle of the waste. Finally, pull the end of the waste back to its original position, tie it into a ring or pinch it with your hand. At this time, the waste can be removed from the end of the sleeve 7 away from the pipe 6, so that the sleeve 7 can continue to collect waste.

[0032] Beneficial effects: Compared with the prior art, this application can effectively reduce the frequency of emptying the collected waste, and at the same time, it is simple and convenient to clean the waste from the sleeve 7.

[0033] like Figures 2 to 4 As shown, in order to further optimize the operation of passing through the middle of the spiral waste, the end of the sleeve 7 away from the pipe 6 is provided with a through hole 71 through which the waste can pass. The outer wall of the sleeve 7 is fixedly provided with a number of winding parts 61 for positioning the waste after passing through the through hole 71. The through hole 71 has a narrowing structure from the outside to the inside, and the periphery of the through hole 71 is formed with a rounded corner structure. The cross-section of the winding part 61 is U-shaped.

[0034] Workers can first pass the waste material through the perforation 71, then wrap and tighten the waste material on the winding part 61 to form a positioning. After the sleeve rod 7 has collected the waste material for a period of time, the waste material on the sleeve rod 7 can be pushed onto the waste material without stopping the machine. At this time, the waste material in the middle of the long spiral waste material is directly passed through. After pulling out a section of waste material from the perforation 71, the waste material at the perforation 71 is cut. Finally, the cut end of the waste material is guided to the end of the waste material wrapped on the winding part 61. The end of the waste material wrapped on the winding part 61 is removed, tied into a ring or pinched by hand. At this time, the cleaning of the waste material on the sleeve rod 7 is completed.

[0035] like Figures 2 to 4 As shown, considering that within a certain length of the material at the beginning, it is necessary to guide the material to adhere to the surface of the subsequent rubber roller of the frame 1, and not to be subjected to the hot melt bonding and cutting of the cutter 4. In order to prevent the waste generated later from being pulled directly to the rubber roller by the material, the guide 8 also includes a cutting part 82 fixedly set on the side near the air knife 5. The cutting part 82 has a cutting edge facing the waste forming. The air blowing port of the air knife 5 is set parallel to the length direction of the cutting edge. For materials of different thicknesses, the position completely separated by the cutter 4 is also different. In order to make it easier for the waste to be guided into the pipe 6 by the gas blown out by the air knife 5, the pipe 6 and the sliding seat 2 are detachably connected by a connector. The connector can position the angle between the pipe end face near the waste end of the pipe 6 and the material surface, so as to adjust the position of the pipe 6 to accommodate the waste and align the position of the waste separated by the cutter 4.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
