Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive machine technology, specifically a dustproof hot melt adhesive machine. Background Technology

[0002] Hot melt adhesive machines are mainly used for automated applications of hot melt adhesive spraying, scraping, rolling, coating, and dispensing. With social development, hot melt adhesive machines are being used in large numbers. However, existing hot melt glue machines still have some problems in use: First, existing hot melt glue machines lack a dustproof structure for the glue dispensing head. The glue dispensing head is the channel through which hot melt glue flows out. If dust enters, it can easily cause blockage of the glue dispensing head, affecting the smoothness of glue dispensing. Secondly, the existing hot melt glue machines lack a structure inside the glue tank to agitate the glue liquid, which can lead to uneven heating or sedimentation of the glue liquid inside the tank, thus affecting the melting effect of the glue liquid. Summary of the Invention

[0003] To address the problems of dust accumulation and uneven heating or sedimentation of adhesive at the dispensing head of existing hot melt glue machines, the purpose of this invention is to provide a dustproof hot melt glue machine.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: a dustproof hot melt glue machine, comprising a main unit, a housing fixedly connected to one side of the main unit, a support rod fixedly connected in a ring array inside the housing, a hot melt glue tank body fixedly mounted on the upper surface of the support rod, a pressure pipe connected to the main unit, a stirring mechanism inside the hot melt glue tank body, a glue tube, an end seat, and a glue dispensing head sequentially connected to the lower surface of the hot melt glue tank body, a dustproof component for use with the glue dispensing head on the outer surface of the end seat, the dustproof component comprising a support frame, the support frame fixedly mounted on one side of the end seat, a servo motor fixedly mounted inside the cavity of the support frame, a round rod fixedly connected to the output end of the servo motor, and a dustproof cover fixedly sleeved on the outer surface of the round rod.

[0005] Preferably, the stirring mechanism includes a DC motor, which is fixedly installed inside the housing. A first sprocket is fixedly connected to the output end of the DC motor. A vertical rod is rotatably connected inside the housing, and a second sprocket is fixedly connected to the top of the vertical rod. A chain meshes between the second sprocket and the first sprocket. A stirring shaft is fixedly connected to the middle of the upper surface of both the first sprocket and the second sprocket. The top of the stirring shaft penetrates the hot melt adhesive bucket body. Stirring heads are fixedly sleeved at equal intervals on the outer surface of the stirring shaft.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This application uses a dustproof component to install a rotating dust cover at the dispensing head. When the dispensing head is not in use, the dust cover can rotate to cover the dispensing head, effectively reducing dust adhesion at the dispensing head, preventing the dispensing head from getting blocked, and thus ensuring the smooth dispensing of glue from the hot melt glue machine. 2. This application incorporates a stirring mechanism within the hot melt adhesive container to ensure uniform heating of the adhesive, prevent sedimentation, and improve the melting effect of the adhesive.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Figure 1-5 As shown, this utility model provides a dustproof hot melt glue machine, including a main unit 1, which is the core control unit of the hot melt glue machine. A housing 5 is fixedly connected to one side of the main unit 1. Support rods 13 are fixedly connected to the inner cavity of the housing 5 in a ring array. A hot melt glue tank body 12 is fixedly installed on the upper surface of the support rods 13. The support rods 13 are arranged in a ring array, which can evenly and stably support the hot melt glue tank body 12. The hot melt glue tank body 12 is used to hold glue liquid. The hot melt glue tank body 12 is a heat preservation tank. The heat preservation tank structure of the hot melt glue tank body 12 can reduce heat loss and keep the hot melt glue in the tank at a suitable temperature for a long time. A sealing cap 7 is movably snapped onto the upper surface of the hot melt glue tank body 12. A pressure cap 4 for use with the sealing cap 7 is bolted to the upper surface of the housing 5. The pressure cap 4 is connected to the housing 5 by bolts to further tighten the sealing cap 7, enhance the sealing effect, and ensure the sealing performance of the hot melt glue tank body 12.

[0016] The hot melt adhesive bucket body 12 and the main unit 1 are connected by a pressure pipe 14. The pressure pipe 14 can transmit air pressure. Using the air pressure generated by the main unit 1, the hot melt adhesive in the hot melt adhesive bucket body 12 is squeezed out by pressure to realize the dispensing operation. The hot melt adhesive bucket body 12 is equipped with a stirring mechanism 3 inside. The stirring mechanism 3 can stir the hot melt adhesive in the hot melt adhesive bucket body 12 to make the adhesive evenly heated, prevent the adhesive from settling, and improve the melting effect of the adhesive. The lower surface of the hot melt adhesive bucket body 12 is connected to a glue tube 10, an end seat 9, and a glue outlet 6 in sequence. The glue tube 10 is used to transport the hot melt adhesive from the hot melt adhesive bucket body 12 to the end seat 9 and the glue outlet 6. One side of the end seat 9 is connected to the glue tube 10. The glue outlet 6 is connected to the lower surface of the end seat 9. The outer surface of the glue tube 10 is equipped with a valve 11, which can control the flow of hot melt adhesive in the glue tube 10.

[0017] A support sleeve 8 for use with the tube 10 is fixedly connected to one side of the housing 5. The outer surface of the tube 10 is fixedly connected to the inner cavity of the support sleeve 8. The support sleeve 8 provides support for the tube 10. The outer surface of the end seat 9 is provided with a dustproof component 2 for use with the dispensing head 6. The dustproof component 2 can protect the dispensing head 6, prevent dust from adhering to the dispensing head 6, avoid clogging of the dispensing head 6, and ensure smooth dispensing.

[0018] The dustproof component 2 includes a support frame 22, which is fixedly installed on one side of the end seat 9. A servo motor 23 is fixedly installed in the inner cavity of the support frame 22, providing an installation position for the servo motor 23. A round rod 24 is fixedly connected to the output end of the servo motor 23, which facilitates the servo motor 23 to drive the round rod 24 to rotate. The end of the round rod 24 facing away from the output end of the servo motor 23 is rotatably connected to one side of the end seat 9 to ensure the smooth rotation of the round rod 24.

[0019] Furthermore, a dust cover 21 is fixedly sleeved on the outer surface of the round rod 24. The dust cover 21 rotates under the drive of the round rod 24. When the dispensing head 6 is not in use, it rotates to the position of the dispensing head 6 to prevent dust from adhering to the dispensing head 6 and ensure smooth dispensing. When the dispensing head 6 is working, it rotates away from the position of the dispensing head 6 without affecting the dispensing operation. The dust cover 21 is a plastic cover. The dust cover 21 made of plastic is lightweight, which is easy for the servo motor 23 to drive to rotate, and at the same time, the cost is low.

[0020] The stirring mechanism 3 includes a DC motor 35, which is fixedly installed inside the housing 5. The output end of the DC motor 35 is fixedly connected to a first sprocket 33, which rotates under the drive of the DC motor 35. A vertical rod 36 is rotatably connected inside the housing 5, and a second sprocket 37 is fixedly connected to the top of the vertical rod 36. The vertical rod 36 provides support for the second sprocket 37, enabling it to rotate stably inside the housing 5. A chain 34 meshes between the second sprocket 37 and the first sprocket 33. A stirring shaft 32 is fixedly connected to the middle of the upper surface of both the first sprocket 33 and the second sprocket 37. The second sprocket 37 cooperates with the first sprocket 33, and the chain 34 transmits power to drive the stirring shaft 32 to rotate.

[0021] Furthermore, the top end of the stirring shaft 32 penetrates the hot melt adhesive container body 12. A sealing ring 38 for use with the stirring shaft 32 is fixedly connected parallel to the lower surface of the hot melt adhesive container body 12. The stirring shaft 32 and the sealing ring 38 are rotatably connected. The sealing ring 38 can prevent hot melt adhesive from leaking from the connection between the stirring shaft 32 and the hot melt adhesive container body 12. Stirring heads 31 are fixedly sleeved at equal intervals on the outer surface of the stirring shaft 32. The stirring heads 31 rotate with the stirring shaft 32, increasing the contact area with the adhesive, improving the stirring effect, making the adhesive more evenly heated, preventing the adhesive from settling, and improving the melting effect of the adhesive.

[0022] Working principle: First, pour the adhesive into the hot melt glue bucket body 12, allowing the adhesive to melt inside the hot melt glue bucket body 12. Then, movably attach the sealing cap 7 to the upper surface of the hot melt glue bucket body 12. Next, connect the pressure cap 4 to the upper surface of the shell 5 with bolts to tighten the sealing cap 7, preventing dust and impurities from entering the hot melt glue bucket body 12 and ensuring the airtightness of the hot melt glue bucket body 12.

[0023] Then, the DC motor 35 in the stirring mechanism 3 is started. The output end of the DC motor 35 drives the first sprocket 33 to rotate. The first sprocket 33 meshes with the second sprocket 37 through the chain 34, so that the second sprocket 37 also starts to rotate. The stirring shaft 32 rotates accordingly. At the same time, the sealing ring 38 prevents the hot melt adhesive from leaking. The rotation of the stirring shaft 32 drives the stirring head 31 to stir the hot melt adhesive in the hot melt adhesive tank body 12, so that the adhesive is heated evenly, prevents the adhesive from settling, and improves the melting effect.

[0024] Next, while starting the main unit 1, open the valve 11. The main unit 1 transmits air pressure to the hot melt glue tank body 12 through the air pressure pipe 14. Under the pressure, the hot melt glue passes from the lower surface of the hot melt glue tank body 12 through the glue pipe 10 and the end seat 9 in sequence, and finally the glue reaches the glue outlet 6 for use.

[0025] When the dispensing head 6 is not in use, the servo motor 23 in the dustproof assembly 2 is started, and the round rod 24 at its output end rotates, which drives the plastic dustproof cover 21 fixedly sleeved on the outer surface to rotate to the position of the dispensing head 6, so as to prevent dust from adhering to the dispensing head 6 and avoid clogging of the dispensing head 6.

[0026] When glue needs to be dispensed, the servo motor 23 rotates in the opposite direction, causing the dust cover 21 to rotate away from the glue dispensing head 6, without affecting the glue dispensing operation.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
