Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive processing, and in particular to a mixing device for hot melt adhesive processing. Background Technology

[0002] Hot melt adhesive is a type of plastic adhesive whose physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic, odorless, and an environmentally friendly chemical product. During the processing of hot melt adhesive, a mixing device is required to mix the various raw materials used to prepare the hot melt adhesive. However, existing mixing devices for hot melt adhesive processing have a relatively simple mixing method for the raw materials and cannot adopt multiple mixing methods. Most of them use a stirring shaft for stirring, which cannot change the overall orientation and angle of the stirring drum during the stirring process. As a result, the raw materials located above and below the stirring drum cannot be fully mixed, which directly leads to poor subsequent hot melt adhesive preparation and processing effects.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0004] This invention proposes a mixing device for hot melt adhesive processing, which solves the above-mentioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows: A mixing device for hot melt adhesive processing includes a base and a mixing drum above the base. A fixed shaft is rotatably mounted on the bottom of the base, and reinforcing plates are fixed at both ends of the fixed shaft. A mounting bracket is rotatably mounted on the top of the reinforcing plates, which are close to each other. One side of the mounting bracket is fixed to the mixing drum. An auxiliary adjustment component for use with the mixing drum is provided on the base. The auxiliary adjustment component includes an arc-shaped plate symmetrically fixed on the base and located below the mixing drum in the front-back direction. Multiple sets of first teeth and auxiliary teeth are sequentially fixed on the top and bottom of the arc-shaped plate in the left-right direction, respectively. A first motor is fixed to the side of the reinforcing plates close to each other by a mounting sleeve. A gear that meshes with the auxiliary teeth is fixed on the output shaft of the first motor. Second teeth that mesh with the first teeth are fixed in a ring shape on the front and back of the outer wall of the mixing drum. A second motor is embedded in the mounting bracket on the front. A stirring shaft is rotatably mounted in the mixing drum, and the output shaft of the second motor is fixed on the stirring shaft.

[0006] The present invention provides a mixing device for hot melt adhesive processing as described above, further comprising: a set of vertical plates and two sets of symmetrical rotating flip frames are fixedly fixed from the inside to the outside on the top of the base; the two sets of flip frames are located on both sides of the mixing drum and are adapted to the mixing drum; and multiple sets of springs are fixed sequentially along the vertical direction on the side of the vertical plates and flip frames that are close to each other.

[0007] The mixing device for hot melt adhesive processing described above is further provided in this utility model as follows: each set of the flipping frames is equipped with multiple sets of rollers that are used in conjunction with the mixing cylinder and rotate sequentially in the up-down direction.

[0008] The present invention provides a mixing device for hot melt adhesive processing as described above, further comprising: multiple sets of rollers uniformly rotating in a fan shape on one side of the arc-shaped plates that are close to each other, and the multiple sets of rollers are located below the mixing cylinder and used in conjunction with the mixing cylinder.

[0010] The present invention provides a mixing device for hot melt adhesive processing as described above, further comprising: at least two sets of springs on each set of the flipping frames.

[0011] In summary, the beneficial effects of this utility model are as follows: 1.

In addition, it can work with the mixing shaft to continuously stir the inside of the mixing drum, thereby enabling multiple forms and directions of mixing to quickly and evenly mix the various raw materials for preparing hot melt adhesive in the mixing drum. The raw materials located above and below the mixing drum are fully mixed, avoiding mixing dead zones and improving the subsequent preparation and processing effect of hot melt adhesive.

[0012] 2. By setting up a flip frame and cooperating with the elastic rebound of the spring, this utility model can provide auxiliary support when the mixing drum swings as a whole, thereby improving the overall stability of the mixing drum during operation and reducing the overall driving pressure of the first motor.

[0013] 3. By setting rollers, this utility model can better support the mixing cylinder with the flipping frame, avoid direct contact between the flipping frame and the mixing cylinder, which would increase the friction between the two and affect the support effect.

[0020] The following will refer to the appendix in the embodiments of this utility model. Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. 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. Example

[0021] A mixing device for hot melt adhesive processing includes a base 1 and a mixing drum 5 located above the base 1. A controller is fixed to the bottom front of the base 1 via an extension frame. The top and bottom of the mixing drum 5 are symmetrically connected with discharge pipes equipped with valves for easy loading and unloading of raw materials. A fixed shaft 2 is rotatably mounted on the bottom of the base 1, with reinforcing plates 3 fixed to both ends of the fixed shaft 2. Mounting brackets 4 are rotatably mounted on the top of the reinforcing plates 3, which are close to each other. One side of the mounting brackets 4 is fixed to the mixing drum 5. An auxiliary mixing assembly for use with the mixing drum 5 is provided on the base 1. The auxiliary mixing assembly includes bottom plates symmetrically fixed along the front-to-back direction. An arc-shaped plate 6 is located on the seat 1 and below the mixing drum 5. Multiple sets of first teeth 10 and auxiliary teeth 9 are fixed sequentially at the top and bottom of the arc-shaped plate 6 along the left and right directions. A first motor 7 is fixed to one side of the reinforcing plate 3 that is close to each other by a mounting sleeve. A gear 8 that meshes with the auxiliary teeth 9 is fixed to the output shaft of the first motor 7. The front and back sides of the outer wall of the mixing drum 5 are both fixed with second teeth 11 that mesh with the first teeth 10 in a ring shape. A second motor 12 is embedded in the front mounting bracket 4. A stirring shaft 13 is mounted longitudinally inside the mixing drum 5 and the output shaft of the second motor 12 is fixed on the stirring shaft 13.

[0022] Specifically, by setting up auxiliary adjustment components, the second motor 12 can drive the stirring shaft 13 to rotate, and perform preliminary mixing of the raw materials in the stirring drum 5. The design of the second motor 12, gear 8 and auxiliary teeth 9 can drive the stirring drum 5 to swing back and forth while stirring inside, and perform secondary mixing of the raw materials. At the same time, by using the meshing of the first teeth 10 and the second teeth 11, the stirring drum 5 can be driven to rotate while swinging back and forth, so that the raw materials at the bottom can be turned to the top, and the raw materials can be mixed a third time. During the stirring process, the overall orientation and angle of the stirring drum 5 are changed. By adopting a multi-form and multi-directional mixing method, the various raw materials for preparing hot melt adhesive in the stirring drum 5 can be quickly and evenly mixed.

[0023] The top of the base 1 is fixed with a set of vertical plates 16 from the inside to the outside and two sets of flip frames 14 are symmetrically rotated. The two sets of flip frames 14 are located on both sides of the mixing drum 5 and are adapted to the mixing drum 5. On the side of the vertical plates 16 and the flip frames 14 that are close to each other, multiple sets of springs 17 are fixed in sequence along the vertical direction.

[0024] Specifically, by utilizing the elastic rebound of spring 17, a continuous pushing force is provided to the flipping frame 14, so that the flipping frame 14 can provide auxiliary support for the mixing drum 5 when the mixing drum 5 swings as a whole, thereby improving the overall stability of the mixing drum 5 during operation.

[0025] Each set of rotating frames 14 is equipped with multiple sets of rollers 15 that rotate sequentially in the up-down direction and are used in conjunction with the mixing drum 5.

[0026] Specifically, the design of multiple sets of rollers 15 can effectively prevent the flipping frame 14 from directly contacting the outer wall of the mixing drum 5, avoid increasing the friction between the mixing drum 5 and the flipping frame 14, improve the support effect of the flipping frame 14 on the mixing drum 5, and avoid noise caused by friction.

[0027] The arc-shaped plates 6 are fan-shaped and rotate evenly on one side, and multiple sets of rollers 18 are installed. All sets of rollers 18 are located below the mixing drum 5 and are used in conjunction with the mixing drum 5.

[0028] Specifically, the design of multiple sets of fan-shaped support rollers 18 can provide continuous rolling support to the bottom of the mixing drum 5, making the mixing drum 5 more stable when swinging and rotating.

[0029] Multiple sets of first teeth 10 and auxiliary teeth 9 are uniformly fixed at the top and bottom of the arc plate 6 along the arc of the arc plate 6.

[0030] Specifically, the first tooth 10 and the auxiliary tooth 9 are uniformly fixed along the arc of the arc plate 6, so that the first tooth 10 and the second tooth 11 can mesh stably, and the auxiliary tooth 9 and the gear 8 can mesh stably, avoiding disengagement, thus improving the stability of the oscillation and rotation of the stirring drum 5.

[0031] Each set of flip frames 14 has at least two sets of springs 17.

[0032] Specifically, the number of springs 17 on each set of flipping frames 14 is limited in order to provide sufficient support and rebound force to the flipping frames 14, thereby further improving the support effect of the flipping frames 14 on the mixing drum 5. The specific usage process is as follows: The user turns on the first motor 7 and the second motor 12 through the controller. At this time, the second motor 12 drives the stirring shaft 13 to rotate, thereby initially stirring the various raw materials for preparing hot melt adhesive in the stirring drum 5. The first motor 7 is preset to rotate a certain number of times, that is, the first motor 7 rotates forward a certain number of times and then rotates backward a certain number of times, so as to intermittently reverse the rotation of the gear 8. At this time, the first motor 7 can drive the gear 8 to rotate, and by utilizing the meshing of the gear 8 and the auxiliary gear 9, the gear 8 can be driven to rotate and move on the auxiliary gear 9, thereby driving the stirring drum 5 to swing back and forth on the arc plate 6 synchronously. Thus, the stirring drum 5 can swing back and forth in the left and right direction while stirring internally, which is beneficial to the mixing process. The raw materials are mixed a second time, and the meshing of the first tooth 10 and the second tooth 11 drives the mixing drum 5 to rotate while oscillating, thus flipping the raw materials at the bottom to the top. This allows for a third mixing of multiple raw materials. During the mixing process, the overall orientation and angle of the mixing drum 5 can be changed, and the mixing shaft 13 can continuously agitate the inside of the mixing drum 5. By adopting a multi-form and multi-directional mixing method, the various raw materials for preparing hot melt adhesive can be quickly and evenly mixed in the mixing drum 5. At the same time, the elastic rebound of the spring 17 provides a certain rebound force to the flipping frame 14, thereby providing real-time support for the oscillating mixing drum 5 and improving the stability of the mixing drum 5 during operation. After the mixing is completed, the user... The mixing drum 5 is swung to one side above the base 1, and the mixed raw materials are discharged through the discharge pipe. By setting an auxiliary mixing component, the second motor 12 drives the mixing shaft 13 to rotate, initially mixing the raw materials inside the mixing drum 5. The design of the second motor 12, gear 8, and auxiliary teeth 9 allows the mixing drum 5 to oscillate left and right while stirring internally, performing a secondary mixing of the raw materials. Simultaneously, the meshing of the first teeth 10 and the second teeth 11 drives the mixing drum 5 to rotate while oscillating, thus flipping the raw materials from the bottom to the top, performing a tertiary mixing. During the mixing process, the overall orientation and angle of the mixing drum 5 are changed, employing a multi-form and multi-directional mixing method to achieve a comprehensive mixing effect. The mixing drum 5 rapidly and uniformly mixes various raw materials for preparing hot melt adhesive. The elastic rebound of the spring 17 continuously provides a pushing force to the tilting frame 14, allowing it to provide auxiliary support to the mixing drum 5 during its overall oscillation, thus improving the overall stability of the mixing drum 5. The design of multiple sets of rollers 15 effectively prevents the tilting frame 14 from directly contacting the outer wall of the mixing drum 5, avoiding increased friction between the mixing drum 5 and the tilting frame 14, improving the support effect of the tilting frame 14 on the mixing drum 5, and preventing noise caused by friction. The design of multiple sets of fan-shaped support rollers 18 provides continuous rolling support to the bottom of the mixing drum 5, making the mixing drum 5 more stable during oscillation and rotation.The first tooth 10 and auxiliary tooth 9 are uniformly fixed along the arc of the arc plate 6, ensuring stable meshing of the first tooth 10 and the second tooth 11, and stable meshing of the auxiliary tooth 9 and the gear 8, preventing disengagement and improving the stability of the stirring drum 5's oscillation and rotation. The limited number of springs 17 on each set of tilting frames 14 provides sufficient support and rebound force, further enhancing the support effect of the tilting frames 14 on the stirring drum 5.

[0033] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).

[0034] The above are merely preferred embodiments of the present utility model and are 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 shall be included within the protection scope of the present utility model.
