Abstract

This utility model discloses a rapid heating device for adhesive raw materials, relating to the field of adhesive processing technology, including a hopper, a feeding unit, and a heating unit. This utility model features a reliable feeding unit. The eccentric rotating block generates centrifugal force during rotation, which in turn drives the discharge cylinder at the lower end of the hopper to swirl, accelerating the falling speed of the material inside the hopper and ensuring the material is evenly dispersed during its descent, facilitating subsequent heating. The material discharged from the discharge cylinder enters the heating cylinder, where a heating plate embedded in the spiral carriage heats its surface. As the material spirals down, it is heated. The spiral carriage provides sufficient heating time, ensuring the material is fully heated when it slides out from the lower end of the spiral carriage. Furthermore, by simultaneously conveying and heating, time consumption is reduced, thus rapidly achieving material heating.

Description

Technical Field

[0001] This utility model relates to the field of adhesive processing technology, specifically to a device for rapid heating of adhesive raw materials. Background Technology

[0002] Adhesives are chemical or polymeric materials that connect and bond different materials or objects through adhesion and cohesion. They are widely used in industrial manufacturing, building decoration, medical repair and other fields. Temperature affects adhesive raw materials throughout their storage, processing and final performance. Heating the materials during adhesive processing is a key process step to improve bonding effect and production efficiency.

[0003] Existing heating devices for adhesive raw materials cannot achieve continuity in the three processes of feeding, heating, and discharging. The heating process of the raw materials is relatively independent, and a special container is required for the materials afterward. This cannot meet the needs of rapid heating and immediate use. Furthermore, temperature loss is easily caused during the subsequent containerization process, resulting in temperature deviations in the materials and affecting subsequent use. Therefore, we propose a rapid heating device for adhesive raw materials. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a rapid heating device for adhesive raw materials. This device features a reliable feeding unit, a hopper that allows for easy pouring of raw materials from various directions, a support ring at the bottom of the hopper to support its swaying motion, and a motor output shaft fixedly connected to one end of an eccentric swivel block. When the motor operates, the rotation of the eccentric swivel block generates centrifugal force, which in turn drives the discharge cylinder at the bottom of the hopper to sway in a circular motion. This swaying motion accelerates the falling speed of the material inside the hopper and ensures that the material is properly positioned at the bottom. The material disperses evenly upon falling, facilitating subsequent heating. It also features a reliable heating unit. Material ejected from the discharge cylinder enters the heating cylinder and slides down the spiral carriage layer by layer. Heating plates embedded within the spiral carriage heat its surface, thus heating the material as it spirals down. The spiral carriage provides sufficient heating time, ensuring adequate heating when the material exits from the bottom. Furthermore, the simultaneous conveying and heating reduces time consumption, rapidly raising the material's temperature and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid heating device for adhesive raw materials, comprising a hopper, a feeding unit, and a heating unit;

[0006] The hopper has a vertical heating cylinder installed at its bottom;

[0007] The feeding unit includes a motor housing, connecting block, eccentric rotating block, feeding cylinder, protective ring, and support ring. The feeding cylinder is fixedly connected to the lower center of the hopper and extends into the heating cylinder. The motor housing is installed at the upper part of the feeding cylinder. The motor housing is fixedly connected to the central axis of the feeding cylinder by three connecting blocks arranged in an outer circumferential array. The motor is installed inside the motor housing with its output shaft facing downward and an eccentric rotating block fixedly connected to its end. The output shaft of the motor is vertically fixedly connected to one end of the eccentric rotating block. The support ring is fitted and supports the lower side of the hopper. A protective ring is fixedly connected to the upper edge of the hopper.

[0008] Heating unit: installed inside the heating cylinder.

[0009] The hopper allows for easy pouring of raw materials from various directions. A support ring, placed at the bottom of the hopper, supports its swaying motion. A connecting block is used to install the motor housing, which protects the internal motor. The motor's output shaft is fixedly connected to one end of an eccentric rotating block. When the motor is running, the rotation of the eccentric rotating block generates centrifugal force, which in turn drives the discharge cylinder at the bottom of the hopper to sway in a circular motion. This swaying motion accelerates the falling speed of the material inside the hopper and ensures that the material is evenly dispersed during the fall, facilitating the subsequent heating process. A protective ring prevents material from being thrown out of the port when the hopper sways.

[0010] Furthermore, the heating unit includes a spiral carriage and a heating plate. The spiral carriage is installed inside the heating cylinder, and its outer side is fixedly connected to the inner wall of the heating cylinder. Within the same horizontal layer, the outer side of the spiral carriage is higher than its inner side. The heating plate is embedded inside the spiral carriage. The material ejected from the discharge cylinder enters the heating cylinder and slides down the spiral carriage layer by layer. The heating plate embedded inside the spiral carriage can heat its surface, thereby heating the material as it spirals down. The spiral carriage provides sufficient heating time for the material. When the material slides out from the lower end of the spiral carriage, it is fully heated. By simultaneously conveying and heating, time consumption can be reduced, thus achieving rapid heating of the material.

[0011] Furthermore, the heating unit also includes a retaining ring, a second support ring, and connecting rods. A retaining ring is fixedly connected to the upper end of the heating cylinder, with its edge extending outwards and its lower outer edge having a rounded corner structure. The retaining ring is placed inside the second support ring. Two connecting rods are fixedly connected to the outer sides of both the second and first support rings. A gap exists between the outer edge of the retaining ring and the inner wall of the second support ring, and a gap exists between the inner ring side of the second support ring and the outer wall of the heating cylinder. The heating cylinder is engaged with the second support ring via the upper retaining ring, which provides a lifting and securing effect for the heating cylinder. The connecting rods connect the support ring component to the mounting frame. The reserved gaps allow space for the heating cylinder to move, and the rounded corner structure of the lower edge of the retaining ring makes the movement of the heating cylinder smoother. When the heating cylinder makes circumferential movements, it accelerates the downward flow of internal materials.

[0012] Furthermore, the heating unit also includes hydraulic cylinders, rubber blocks, and a control center. Four hydraulic cylinders are arranged in a circular array on the lower outer side of the heating cylinder. The hydraulic cylinders are horizontally positioned, and their extension and retraction ends are perpendicular to the outer side of the heating cylinder. Rubber blocks are fixedly connected to the extension and retraction ends of the hydraulic cylinders. A control center is installed on the front side of the heating cylinder. The control center includes a PLC control module and a temperature control module, which is bidirectionally electrically connected to the heating plate. The PLC control module inside the control center can control the four hydraulic cylinders to work sequentially. The four hydraulic cylinders strike the heating cylinder in sequence, causing it to oscillate in a circular motion, thereby accelerating the material being ejected. The rubber blocks can reduce the noise generated during the striking and provide anti-wear protection to the contact surfaces.

[0013] Furthermore, it also includes a fixing base and a plug. Each connecting rod has a plug installed at its outer end, with the plug fixedly connected to the center of the fixing base. The connecting rod is slidably connected inside the plug, and bolts on the outer side are fixed to the plug. Bolt through holes are provided at the four corners of the fixing base. The fixing base is used to fix to an external mounting frame or wall, thereby installing the support ring at a specified height. The connecting rod, through its slidable connection with the plug, allows adjustment of the overall length of the connecting rod frame and the spatial position of the upper and lower support rings on the same central axis, thus vertically aligning the hopper with the heating cylinder.

[0014] Furthermore, it also includes a receiving rack, receiving drawers, and handles. A flat cylindrical receiving rack is installed at the lower end of the heating cylinder. Hydraulic cylinders are fixed at four points on the upper end of the receiving rack, in all directions. The receiving rack is hollow inside, and a circular through hole communicating with the interior of the heating cylinder is opened in the middle of the upper end. Two receiving drawers are longitudinally slidably connected inside the receiving rack, and handles are fixedly connected to the front end of the receiving drawers. The receiving rack is used for installing the receiving drawers. When one layer of the receiving drawers is pulled out, the other layer continues to receive the falling material, thus realizing continuous material receiving and unloading functions. The handles facilitate the pulling out of the receiving drawers.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This rapid heating device for adhesive raw materials has the following advantages:

[0016] 1. It has a reliable feeding unit, and the hopper can easily pour raw materials into the hopper from all directions. The support ring is supported at the bottom of the hopper, thus supporting the hopper to shake. The output shaft of the motor is fixedly connected to one end of the eccentric swivel block. When the motor is working, the rotation of the eccentric swivel block can generate a centrifugal force, which in turn drives the discharge cylinder at the bottom of the hopper to swing in a circular motion. When the discharge cylinder swings, it can accelerate the falling speed of the material inside the hopper and make the material evenly dispersed when falling, which is convenient for the subsequent heating process.

[0017] 2. It has a reliable heating unit. The material thrown out from the discharge cylinder enters the heating cylinder and slides down the spiral carriage layer by layer. The heating plate embedded in the spiral carriage can heat its surface. As the material slides down the spiral, it is heated. The spiral carriage allows the material sufficient heating time. When the material slides out from the bottom of the spiral carriage, it can be fully heated. By conveying and heating at the same time, the time consumption can be reduced, and the material can be heated quickly.

[0018] 3. This utility model has a reliable feeding unit. The hopper can easily pour raw materials into it from all directions. A support ring is placed at the bottom of the hopper to support its swaying motion. The motor's output shaft is fixedly connected to one end of the eccentric swivel block. When the motor is working, the rotation of the eccentric swivel block generates centrifugal force, which drives the discharge cylinder at the bottom of the hopper to sway in a circular motion. During this swaying motion, the discharge cylinder accelerates the falling speed of the material inside the hopper and ensures that the material is evenly dispersed during its descent. For subsequent heating processes, it also has a reliable heating unit. The material thrown out from the discharge cylinder enters the interior of the heating cylinder and slides down the spiral carriage layer by layer. The heating plate embedded in the spiral carriage can heat its surface, thereby heating the material as it spirals down. The spiral carriage allows the material sufficient heating time. When the material slides out from the bottom of the spiral carriage, it can be fully heated. Moreover, by conveying and heating simultaneously, the time consumption can be reduced, thereby quickly achieving the heating of the material. Attached Figure Description

Detailed Implementation

[0025] 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.

[0026] Please see Figures 1-5 This embodiment provides a technical solution: a rapid heating device for adhesive raw materials, including a hopper 1, a feeding unit 3 and a heating unit 4;

[0027] A vertical heating cylinder 2 is installed below the hopper 1;

[0028] The feeding unit 3 includes a motor housing 31, a connecting block 32, an eccentric rotating block 33, a feeding cylinder 34, a protective ring 35, and a support ring 36. The feeding cylinder 34 is fixedly connected to the lower center of the hopper 1. The feeding cylinder 34 extends into the heating cylinder 2. The motor housing 31 is installed at the upper part of the inside of the feeding cylinder 34. The motor housing 31 is fixedly connected to the central axis of the feeding cylinder 34 by three connecting blocks 32 arranged in an outer circumferential array. The motor is installed inside the motor housing 31. The output shaft of the motor faces downward and is fixedly connected to the end of the eccentric rotating block 33. The output shaft of the motor is vertically fixedly connected to one end of the eccentric rotating block 33. The support ring 36 is sleeved and supported on the lower side of the hopper 1. The upper edge of the hopper 1 is fixedly connected to the protective ring 35.

[0029] Heating unit 4: installed inside heating cylinder 2.

[0030] The hopper 1 allows for easy pouring of raw materials from various directions. The support ring 36 supports the bottom of the hopper 1, thus enabling the hopper 1 to shake. The connecting block 32 is used for the installation of the motor housing 31, which protects the internal motor. The output shaft of the motor is fixedly connected to one end of the eccentric rotating block 33. When the motor is working, the rotation of the eccentric rotating block 33 generates a centrifugal force, which drives the discharge cylinder 34 at the lower end of the hopper 1 to swing in a circular motion. When the discharge cylinder 34 swings, it accelerates the falling speed of the material inside the hopper 1 and makes the material evenly dispersed during the fall, facilitating the subsequent heating process. The protective ring 35 prevents the material from being thrown out of the port when the hopper 1 shakes.

[0031] The heating unit 4 includes a spiral carriage 41 and a heating plate 42. The spiral carriage 41 is installed inside the heating cylinder 2. The outer side of the spiral carriage 41 is fixedly connected to the inner wall of the heating cylinder 2. Within the same horizontal layer, the outer side of the spiral carriage 41 is higher than the inner side. The heating plate 42 is embedded inside the spiral carriage 41. The material ejected from the discharge cylinder 34 enters the heating cylinder 2 and slides down the spiral carriage 41 layer by layer. The heating plate 42 embedded inside the spiral carriage 41 can heat its surface, thereby heating the material as it spirals down. The spiral carriage allows the material sufficient heating time. When the material slides out from the lower end of the spiral carriage 41, it can be fully heated. By simultaneously conveying and heating, the time consumption can be reduced, thus achieving rapid heating of the material.

[0032] The heating unit 4 also includes a retaining ring 43, a second support ring 44, and a connecting rod 45. The upper end of the heating cylinder 2 is fixedly connected to the retaining ring 43. The edge of the retaining ring 43 extends outward, and the lower edge of its outer end is rounded. The retaining ring 43 is placed inside the second support ring 44. The outer sides of the second support ring 44 and the first support ring 36 are fixedly connected to two connecting rods 45 on the left and right. There is a gap between the outer edge of the retaining ring 43 and the inner wall of the second support ring 44, and there is a gap between the inner ring side of the second support ring 44 and the outer wall of the heating cylinder 2. The heating cylinder 2 is engaged with the second support ring 44 via the upper retaining ring 43. The second support ring 44 serves to suspend and hold the heating cylinder 2. The connecting rod 45 is used to connect the support ring component to the mounting frame. The reserved gap provides space for the heating cylinder 2 to swing. The rounded corner structure of the lower edge of the retaining ring 43 makes the heating cylinder 2 swing more smoothly. When the heating cylinder 2 makes circumferential swinging, it can accelerate the downward slide of the internal material.

[0033] The heating unit 4 also includes hydraulic cylinders 46, rubber blocks 47, and a control center 48. Four hydraulic cylinders 46 are arranged in a circular array on the lower outer side of the heating cylinder 2. The hydraulic cylinders 46 are horizontally positioned, and their extension and retraction ends are perpendicular to the outer side of the heating cylinder 2. Rubber blocks 47 are fixedly connected to the extension and retraction ends of the hydraulic cylinders 46. The control center 48 is installed on the front side of the heating cylinder 2. The control center 48 includes a PLC control module and a temperature control module. The temperature control module is bidirectionally electrically connected to the heating plate 42. The PLC control module inside the control center 48 can control the four hydraulic cylinders 46 to work sequentially. The four hydraulic cylinders 46 strike the heating cylinder 2 in sequence, causing the heating cylinder 2 to oscillate, thereby accelerating the material being thrown out. The rubber blocks 47 can reduce the noise generated during the striking and provide anti-wear protection to the contact surfaces.

[0034] It also includes a fixed base 5 and a plug 6. Each connecting rod 45 has a plug 6 installed at its outer end. The plug 6 is fixedly connected to the center of the fixed base 5. The connecting rod 45 is slidably connected to the inside of the plug 6, and the bolts on the outside are fixed to the plug 6. Bolt through holes are provided at the four corners of the fixed base 5. The fixed base 5 is used to fix to the external mounting frame or wall, so as to install the support ring at a specified height. The connecting rod 45 is slidably connected to the plug 6, so as to adjust the overall length of the connecting rod frame and adjust the spatial position of the upper and lower support rings on the same central axis, so as to vertically align the hopper 1 and the heating cylinder 2.

[0035] It also includes a receiving rack 7, a receiving drawer 8, and a handle 9. A flat cylindrical receiving rack 7 is installed at the lower end of the heating cylinder 2. A hydraulic cylinder 46 is installed and fixed at four points on the upper end of the receiving rack 7. The receiving rack 7 is hollow inside, and a circular through hole communicating with the inside of the heating cylinder 2 is opened in the middle of the upper end. Two receiving drawers 8 are longitudinally slidably connected inside the receiving rack 7. A handle 9 is fixedly connected to the front end of the receiving drawer 8. The receiving rack 7 is used for the installation of the receiving drawers 8. When one layer of the two receiving drawers 8 is pulled out, the other layer continues to receive the falling material, thereby realizing continuous material receiving and pouring functions. The handle 9 facilitates the pulling out of the receiving drawer 8.

[0036] The working principle of the adhesive raw material rapid heating device provided by this utility model is as follows: This device has a reliable feeding unit 3, and the hopper 1 can easily pour raw materials into the hopper from all directions. The support ring 36 supports the bottom of the hopper 1, thereby supporting the shaking of the hopper 1. The connecting block 32 is used for the installation of the motor housing 31. The motor housing 31 is used to protect the internal motor. The output shaft of the motor is fixedly connected to one end of the eccentric rotating block 33. Thus, when the motor is working, a centrifugal force can be generated by the rotation of the eccentric rotating block 33, which in turn drives the discharge cylinder 34 at the lower end of the hopper 1 to make a circular swing. When the discharge cylinder 34 swings, it can accelerate the falling speed of the material inside the hopper 1 and make the material evenly dispersed when falling, which is convenient for the subsequent heating process. The protective ring 35 can prevent the material from being thrown out from the port when the hopper 1 shakes. This device also features a reliable heating unit 4. Material ejected from the discharge cylinder 34 enters the heating cylinder 2 and slides down the spiral slide 41 layer by layer. Heating plates 42 embedded inside the spiral slide 41 heat its surface, thus heating the material as it spirals down. The spiral shape of the slide provides sufficient heating time, ensuring adequate heating when the material slides out from the lower end of the spiral slide 41. Furthermore, the simultaneous conveying and heating reduces time consumption, enabling rapid heating of the material. The heating cylinder 2 is engaged with the second support ring 44 via a retaining ring 43 at its upper end. The second support ring 44... The connecting rod 45 serves as a hoisting and clamping mechanism, connecting the ring component to the mounting frame. The reserved gap provides space for the heating cylinder 2 to swing. The rounded corners of the lower edge of the retaining ring 43 ensure smoother swinging of the heating cylinder 2, accelerating the downward movement of internal materials during circumferential swaying. The PLC control module inside the control center 48 controls four hydraulic cylinders 46 to work sequentially. These cylinders strike the heating cylinder 2 in sequence, causing it to swing circumferentially, thus accelerating the ejection of materials. The rubber block 47 reduces noise generated during striking and provides anti-wear protection to the contact surfaces. In addition, the fixing base 5 is used to fix it to the external mounting frame or wall, so as to install the support ring at a specified height. The connecting rod 45 is slidably connected to the insert 6, so as to adjust the overall length of the connecting rod frame and adjust the spatial position of the upper and lower support rings on the same central axis, so as to make the material hopper 1 and the heating cylinder 2 vertically aligned. The receiving rack 7 is used for the installation of the receiving drawer 8. When one layer of the receiving drawer 8 is pulled out, the other layer continues to hold the falling material, so as to realize the continuous receiving and pouring function. The handle 9 can facilitate the pulling out of the receiving drawer 8.

[0037] It is worth noting that the input terminals of the hydraulic cylinder 46, heating plate 42, and motor inside the motor housing 31 disclosed in the above embodiments are all electrically connected to the output terminal of an external power supply through the control center 48. The control center 48 controls the operation of the hydraulic cylinder 46, heating plate 42, and motor inside the motor housing 31 using methods commonly used in the prior art.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
