A gluing mechanism

Abstract

This application relates to a gluing mechanism, comprising: a frame; a roller rotatably connected to the frame; a glue storage structure disposed on one side of the roller, the glue storage structure having a gluing channel for glue to pass through, the outlet of the gluing channel facing the roller; and an adjustment structure including a flow restrictor slidably connected to the glue storage structure and disposed on the gluing channel. When the flow restrictor moves, the area through which glue can pass through the gluing channel changes. This application uses a flow restrictor so that when glue passes through the gluing channel, the flow restrictor blocks a portion of the glue from passing through, that is, it limits the flow rate of glue that can pass through the gluing channel, thereby matching the amount of glue flowing out of the gluing channel with the amount of glue to be coated on the roller. Therefore, this application can avoid excessive glue on the scraper by adjusting the position of the flow restrictor.

Description

Technical Field

[0001] This application relates to the technical field of adhesive coating, and in particular to an adhesive coating mechanism. Background Technology

[0002] The gluing mechanism is a mechanism that evenly applies glue to the surface of materials to bond them together. Currently, the main application method is to first evenly apply glue to a roller, and then roll the roller over the material to evenly coat the material with the glue applied to the roller.

[0003] The roller is fixed in position but can rotate. At certain specific locations near the roller, there is an adhesive application device and a scraper for applying adhesive to the roller. The device applies adhesive to the roller surface along the length of the roller, meaning that all rollers passing through this location will be covered with adhesive. After the adhesive-covered area on the roller passes the scraper, the scraper will scrape off the excess adhesive on the roller, controlling the thickness of the adhesive on the roller and completing the process of applying adhesive to the roller. The position on the roller with the controlled adhesive thickness is in contact with the material, and as the material moves, the adhesive is applied to the material.

[0004] In the prior art, the flow rate of the glue outlet of the glue-applying device is fixed, that is, the amount of glue added to each part of the roller surface by the glue-applying device is the same and does not change. During the process of applying glue to the roller, if it is necessary to control the thickness of the glue applied to the material, it is necessary to adjust the distance between the scraper and the roller. The scraper will scrape the excess glue on the roller surface onto the scraper. However, if there is a large amount of excess glue at all positions on the roller, it will result in too much excess glue on the scraper, or even glue overflowing from both sides of the scraper. Utility Model Content

[0005] This application provides a glue-applying mechanism to solve the problem of excessive glue on the glue scraper in related technologies.

[0006] In a first aspect, a gluing mechanism is provided, comprising:

[0007] frame;

[0008] The roller is rotatably connected to the frame.

[0009] The glue storage structure is located on one side of the roller. The glue storage structure is provided with a glue passage for glue to pass through, and the outlet of the glue passage faces the roller.

[0010] The adjustment structure includes a flow restrictor, which is slidably connected to the glue storage structure. The flow restrictor is located at the inlet or outlet of the glue passage. When the flow restrictor moves, the area between the flow restrictor and the outlet of the glue passage changes at the cross-section of the outlet of the glue passage.

[0011] In some embodiments, the adjustment structure further includes a cam and a top plate, the top plate being fixedly connected to the flow restrictor, the cam being rotatably connected to the glue storage structure, and the cam being in close contact with the top plate.

[0012] In some embodiments, the glue storage structure is provided with a driving member, a first limiting member, and a connecting member. The driving member is connected to the frame, and one end of the driving member is connected to the connecting member. The first limiting member is connected to the glue storage structure, and the connecting member is rotatably connected within the first limiting member. The connecting member is connected to a cam.

[0013] In some embodiments, the adjustment structure further includes a guide rod and a spring. The guide rod is connected to the glue storage structure, and the spring is arranged around the guide rod. The two ends of the spring are respectively fixedly connected to the top plate and one end of the guide rod.

[0014] In some embodiments, the glue storage structure includes a baffle, a bottom plate, and a second limiting member;

[0015] A glue passage is formed between the baffle and the base plate. The flow limiting component is a plate. The second limiting component is connected to the baffle. The flow limiting component is slidably connected between the limiting component and the baffle. The flow limiting component is in close contact with the baffle.

[0016] In some embodiments, a scraper is provided on the side of the base plate facing the roller, and a heating element is provided inside the base plate.

[0017] In some embodiments, the glue storage structure also includes a surrounding plate;

[0018] Both the baffle and the surrounding plate are fixedly connected to the base plate, and the baffle and the surrounding plate are fixedly connected. The baffle, the base plate, and the surrounding plate form a storage space for storing glue, and the glue passage is connected to the storage space.

[0019] In some embodiments, a distance control structure is provided between the frame and the glue storage structure. The distance control structure includes a track and a slider. The track is fixedly connected to the frame, the slider is fixedly connected to the glue storage structure, and the slider is slidably connected within the track.

[0020] In some embodiments, the distance control structure further includes a screw rotatably connected to the track, and the slider has a screw hole through which the screw passes, with the screw threadedly engaging with the screw hole.

[0021] In some embodiments, a separator is provided on the frame, with one side of the separator closely attached to the roller, and the width of the vertical cross-section of the separator gradually increases along the rotation direction of the roller.

[0022] This application provides a glue-applying mechanism. Because this application includes a flow-limiting component, when the glue passes through the glue-applying channel, the flow-limiting component will block a portion of the glue from passing through, thus limiting the flow rate of the glue in the glue-applying channel. This ensures that the amount of glue flowing out of the glue-applying channel matches the amount of glue that needs to be applied to the roller. Therefore, this application can control the amount of glue flowing out of the glue-applying channel by adjusting the position of the flow-limiting component, thereby avoiding excessive glue on the glue scraper.

[0031] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] This application provides a glue-applying mechanism that can solve the problem of excessive glue on the glue scraper in related technologies.

[0033] Please see Figures 1 to 6 A gluing mechanism includes: a frame 1, a roller 2, a glue storage structure 3, and an adjusting structure 4. The roller 2 is rotatably connected to the frame 1 and is disposed on one side of the roller 2. The glue storage structure 3 is provided with a glue channel 31 for supplying glue. The outlet of the glue channel 31 faces the roller 2. The adjusting structure 4 includes a flow restrictor 41, which is slidably connected to the glue storage structure 3. The flow restrictor 41 is disposed at the inlet or outlet of the glue channel 31. When the flow restrictor 41 moves, the area between the flow restrictor 41 and the outlet of the glue channel 31 changes at the cross-section at the outlet of the glue channel 31.

[0034] In this embodiment, the position of the frame 1 is fixed, and the two sides of the roller 2 are rotatably connected to the frame 1. A motor is provided on the frame 1, and the output end of the motor is connected to one end of the roller 2 through a chain and a sprocket. The motor drives the roller 2 to rotate, so that the roller 2 always rotates in one direction during the operation of this application. The glue flows out from the outlet of the glue channel 31 and falls onto the surface of the roller 2. The glue covers the surface of the roller 2. When the glue-covered part of the roller 2 passes the scraper 8, the scraper 8 will scrape the glue that exceeds the thickness onto the scraper 8. When the roller 2 is in contact with the material, the thickness of the glue on the roller 2 is consistent.

[0035] Before using this application, the flow restrictor 41 needs to be slid according to the distance between the scraper 8 and the roller 2 to adjust its position so that the area through which the glue can pass in the glue channel 31 matches the thickness of the glue applied on the roller 2. In this application, the flow restrictor 41 can be a plate or a plug with a bevel. Both of these methods can change the flow rate of the glue flowing out of the glue channel 31 by moving the flow restrictor 41, so that there will not be too much excess glue on the scraper 8. In a preferred embodiment, the flow restrictor 41 is a plate. The plate can be set at the entrance or exit of the glue channel 31. The plate moves in the vertical direction to change the area covered by the plate on the glue channel 31.

[0036] Furthermore, in this embodiment, the adjustment structure 4 also includes a cam 42 and a top plate 43. The top plate 43 is fixedly connected to the flow restrictor 41, and the cam 42 is rotatably connected to the glue storage structure 3. The cam 42 is in close contact with the top plate 43, and the cam 42 rotates around a point. The side of the cam 42 contacts the top plate 43. When the cam 42 rotates, the top plate 43 moves accordingly based on the change in distance between the contact point of the cam 42 and the top plate 43 and the rotation point of the cam 42. The movement of the top plate 43 drives the flow restrictor 41 to move. Since the size of the glue passage 31 in this application is not large, that is, the distance that the flow restrictor 41 needs to move is not large, compared with using a screw or other lifting methods, directly using the cam 42 can be more convenient and easier to adjust, and will not occupy too much space above or below the roller 2, affecting the contact between the material and the roller 2.

[0037] Furthermore, in this embodiment, the glue storage structure 3 is provided with a driving component 5, a first limiting component 34, and a connecting component 7. The driving component 5 is connected to the frame 1, and one end of the driving component 5 is connected to the connecting component 7. The first limiting component 34 is connected to the glue storage structure 3, and the connecting component 7 is rotatably connected within the first limiting component 34. The connecting component 7 is connected to the cam 42. The driving component 5 is a motor, and the output end of the driving component 5 is fixedly connected to the connecting component 7. The connecting component 7 is a round rod. The structure of the first limiting component 34 is as follows: Figure 4 As shown, the first limiting member 34 is provided with a bearing, the connecting member 7 passes through the bearing, and there are two first limiting members 34. The two first limiting members 34 are located at the two ends of the connecting member 7 respectively, so that the connecting member 7 remains horizontal when rotating. The connecting member 7 is driven to rotate by the driving member 5, and the connecting member 7 drives the cam 42 to rotate.

[0038] Specifically, in this embodiment, the adjustment structure 4 also includes a guide rod 44 and a spring 45. The guide rod 44 is connected to the glue storage structure 3, and the spring 45 is arranged around the guide rod 44. The two ends of the spring 45 are respectively fixedly connected to the top plate 43 and one end of the guide rod 44. The spring 45 will continuously provide a force towards the cam 42 to the top plate 43, so that the cam 42 and the top plate 43 always remain in close contact. The guide rod 44 can guide the movement of the top plate 43, and at the same time, it can also prevent the spring 45 from twisting.

[0039] Preferably, in this embodiment, the glue storage structure 3 includes a baffle 32, a bottom plate 33, and a second limiting member 6. A glue passage 31 is formed between the baffle 32 and the bottom plate 33. In a preferred embodiment, the flow limiting member 41 is a plate. The second limiting member 6 is connected to the baffle 32. The flow limiting member 41 is slidably connected between the limiting member and the baffle 32. The flow limiting member 41 is in close contact with the baffle 32. The baffle 32 is vertically arranged. The top plate 43 is perpendicular to the flow limiting member 41. The guide rod 44 is arranged on the baffle 32. By raising and lowering the flow limiting member 41, the distance between the flow limiting member 41 and the bottom plate 33 is adjusted, thereby controlling the flow rate of glue flowing out from the outlet of the glue passage 31.

[0040] A scraper 8 is provided on the side of the base plate 33 facing the roller 2. When the glue flows out from the outlet of the glue channel 31, it falls onto the roller 2 through the scraper 8. Because the glue itself is sticky, it will not break and fall directly when it is between the scraper 8 and the roller 2. When the glue adhering to the roller 2 passes through the scraper 8, the scraper 8 will intercept the excess glue, so that the thickness of the glue passing through the roller 2 is uniform. This application combines the glue storage object and the scraper 8 into one structure, that is, the scraper 8 and the base plate 33 are combined, which can greatly save the space occupied by the device.

[0041] The base plate 33 is equipped with a heating element. The adhesive is divided into hot adhesive and cold adhesive. Cold adhesive can flow at room temperature, while hot adhesive cannot flow normally at room temperature. Therefore, when using hot adhesive, it is necessary to heat it. Thus, this application adds a heating element to the base plate 335. The heating element is an electromagnetic heating device. Electromagnetic heating devices are existing technology and will not be described in detail here. The hot adhesive in the storage space is heated by the electromagnetic heating device and the conduction of the heat-conducting material, so that the device is also suitable for hot adhesive.

[0042] In a preferred embodiment, the glue storage structure 3 further includes a surrounding plate 35, a baffle 32, and the surrounding plate 35 are all fixedly connected to the base plate 33. The baffle 32 is fixedly connected to the surrounding plate 35. The baffle 32, the base plate 33, and the surrounding plate 35 form a storage space for storing glue. The glue passage 31 is connected to the storage space. Workers can pour glue into the storage space. The glue can enter the glue passage 31 from the storage space and flow out from the outlet of the glue passage 31.

[0043] like Figure 6 As shown, in this embodiment, a distance control structure 9 is provided between the frame 1 and the glue storage structure 3. The distance control structure 9 includes a track 91 and a slider 92. The track 91 is fixedly connected to the frame 1, and the slider 92 is fixedly connected to the glue storage structure 3. The slider 92 is slidably connected within the track 91. The distance control structure 9 also includes a screw 93, which is rotatably connected to the track 91. The slider 92 has a screw hole through which the screw 93 passes. The screw 93 is threadedly engaged with the screw hole. The position of the screw 93 on the track 91 is fixed. By rotating the screw 93, the slider 92 is driven to move on the track 91 to adjust the distance between the scraper 8 and the roller 2. The screw 93 can precisely adjust the position of the scraper 8. At the same time, the screw 93 has a self-locking function, that is, after the position of the scraper 8 is adjusted, the position of the scraper 8 is fixed, which is convenient for the operator to use.

[0044] like Figure 2As shown, in this embodiment, the frame 1 is provided with a separator 10. One side of the separator 10 is closely attached to the roller 2. The width of the vertical cross-section of the separator 10 gradually increases along the rotation direction of the roller 2. When the material is pearl cotton and it contacts the roller 2 from below, the material will be separated from the roller 2 by the separator 10 after contacting the roller 2, thus preventing the material from rotating with the roller 2 due to glue and affecting subsequent processing.

[0045] The working principle of this application is as follows:

[0046] Before use, this application requires adjusting the distance between the scraper 8 and the roller 2 by rotating the screw 93 according to the thickness of the glue applied on the roller 2. Then, the drive motor drives the connector 7 to rotate, adjusting the distance between the contact point of the cam 42 and the top plate 43 and the rotation point of the cam 42, that is, adjusting the distance between the flow limiting component 41 and the bottom plate 33, controlling the flow rate of the glue flowing out from the outlet of the glue channel 31, so that there will not be too much excess glue on the scraper 8.
