Description

Technical Field

[0001] The utility model relates to the technical field of adhesive feeding, in particular to an adhesive reaction device for quantitative feeding. Background Art

[0002] One of the most important auxiliary materials of adhesives, it is widely used in packaging operations. When adding materials to existing adhesive devices, relevant staff are required to measure them once outside the device, which may cause errors, making it impossible to accurately add adhesives, resulting in unqualified finished adhesives. Existing adhesives require accurate addition during the production process, otherwise the quality of subsequent finished adhesives will be reduced. Now, when adding raw materials and reaction substances, most of the staff weigh them first, and then add them through the feeding port of the reaction device. This operation method is prone to low addition efficiency and is extremely wasteful of manpower and time.

[0003] After searching, a Chinese utility model patent with Chinese patent publication number CN214598948U discloses an adhesive reaction device with precise feeding, which includes a base, a support plate and a storage tank.

The adhesive reaction device with precise feeding can make the adhesive more evenly placed through an adjusting mechanism, and the precise feeding mechanism can well control the amount of adhesive added, thereby improving the practicability of the device and being suitable for use in the reaction device.

[0004] The above patent has the following problems: 1. When the adhesive is added in a quantitative manner, the amount of adhesive added is observed by human eyes through an observation window, and the amount of adhesive added is basically controlled manually. There is a lack of an auxiliary weighing and quantitative device, resulting in inaccurate addition of the adhesive and a large error. 2. Different quantities of adhesives require different stirring rates for mixing, and the stirring power of the mixer cannot be adjusted accordingly according to the quantity of the adhesive. In view of this, we propose a quantitative addition adhesive reaction device. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1-Figure 4 As shown, a quantitative feeding adhesive reaction device includes a reaction bin 1, a stirring motor is installed at the top of the reaction bin 1, the output shaft of the stirring motor is connected to a stirring rod, a quantitative feeding bin 2 is fixedly connected to the top of the reaction bin 1, a quantitative weighing device 3 is arranged inside the quantitative feeding bin 2, an adhesive storage bin 4 is installed on the quantitative feeding bin 2, and a stirring gear adjustment device 5 is arranged on the surface of the reaction bin 1 at the bottom of the quantitative feeding bin 2.

[0024] In this embodiment, the quantitative weighing device 3 includes a feeding motor 31, the end of which is installed on the top of the quantitative feeding bin 2, the output shaft of the feeding motor 31 is connected to the clamping shaft 32, the surface of the clamping shaft 32 is slidably connected to the clamping sleeve 33, the bottom end of the clamping sleeve 33 is fixedly connected to a receiving tray 34, the receiving tray 34 is fixedly connected to a receiving bin 35, the bottom end of the receiving tray 34 is rotatably connected to a feeding tray 36, the bottom end of the feeding tray 36 is fixedly connected to a feeding bin 37, and the bottom end of the feeding tray 36 is fixedly connected to a weighing base 38. The adhesive after quantitative unloading is temporarily stored in the receiving bin 35. At this time, by starting the unloading motor 31, the output shaft of the unloading motor 31 drives the receiving plate 34 on the clamping sleeve 33 to rotate through the clamping shaft 32, and the receiving plate 34 drives the adhesive material to be transported as a whole through the receiving bin 35. When the receiving bin 35 rotates to the unloading bin 37, the adhesive is unloaded from the unloading bin 37 to the reaction bin 1, further completing the adhesive feeding work after quantitative weighing. When the unloading motor 31 is working, the weighing sensor in the weighing base 38 stops weighing.

[0025] Furthermore, the surface of the receiving tray 34 is movably connected to the inner wall of the quantitative feeding bin 2, the surface of the discharge tray 36 is slidably connected to the inner wall of the quantitative feeding bin 2, the surface of the discharge bin 37 is slidably connected to the top of the reaction bin 1, and a weighing sensor is installed inside the weighing base 38. The weighing base 38 weighs the discharge tray 36 as a whole during the docking period through the weighing sensor inside it. When the weighing base 38 weighs the required weight of the adhesive, it immediately transmits the information to the control valve through the central control panel, and the control valve stops the discharge work, thereby achieving the effect of quantitative discharge of the adhesive.

[0026] Example 2

[0027] See also Figure 1-Figure 4 As shown, the stirring gear adjustment device 5 includes a control base 51 and a linkage device 56. The surface of the control base 51 is fixedly connected to the surface of the reaction chamber 1. The control base 51 is internally rotatably connected to a contact head 52. The inner wall of the control base 51 is fixedly connected to a connecting plate 54. The surface of the connecting plate 54 is elastically connected to a metal plate 55 via a spring.

[0028] Furthermore, a touch plate 53 is fixedly connected to the surface of the contact head 52, and both sides of the metal plate 55 are slidably connected to the inner wall of the control base 51. The surface of the metal plate 55 contacts the surface of the touch plate 53. After the metal plate 55 contacts the touch plate 53, an electrical circuit is generated, and then an electrical signal is generated. The number of touch plates 53 is set to multiple, and a circular array is distributed on the contact head 52. Different touch plates 53 generate different electrical signals. The central control panel determines the amount of adhesive discharge according to different electrical signals, and controls the stirring motor to perform corresponding power work according to the electrical signals.

[0029] It is worth noting that the linkage device 56 includes a frame rod 561, the end of which is fixedly connected to the surface of the contact head 52, and the inner wall of the frame rod 561 is slidably connected to a bent rod 562, one end of the bent rod 562 close to the frame rod 561 is fixedly connected to a limit column, and the surface of the bent rod 562 is slidably connected to the bottom end of the quantitative feeding bin 2. The bottom of the weighing base 38 is elastically connected to the inside of the quantitative feeding bin 2 through a spring, and the bottom end of the weighing base 38 is fixedly connected to the end of the bent rod 562. The gravity of the amount of adhesive added drives the curved rod 562 on the weighing base 38 to move, and the curved rod 562 exerts force on the frame rod 561 and drives the contact head 52 to rotate. The contact head 52 drives the touch plates 53 at different positions thereon to contact the metal plate 55 according to different rotation angles. The touch plates 53 will generate electrical signals after contacting the metal plate 55. Due to the change in the rotation angle of the contact head 52, the position of the touch plates 53 on the contact head 52 that contact the metal plate 55 also changes. Different touch plates 53 generate different electrical signals. The central control board determines the amount of adhesive fed according to different electrical signals, and controls the stirring motor to perform corresponding power work according to the electrical signals. The greater the amount of adhesive added, the longer the downward movement distance of the curved rod 562, that is, the greater the rotation angle of the contact head 52, the greater the power of the hollow plate to control the operation of the stirring motor, thereby achieving the effect that the reaction chamber 1 can control the stirring rate of the stirring motor according to the amount of adhesive added.

[0030] When a quantitative feeding adhesive reaction device of the utility model is in use, a control valve is provided at the discharge port of the adhesive storage bin 4 to control the amount of discharge. During the discharge, the adhesive is discharged into the inside of the receiving bin 35, and the weighing base 38 weighs the discharge tray 36 as a whole during the connection period through the weighing sensor inside it. When the weighing base 38 weighs the required adhesive weight, the information is immediately transmitted to the control valve through the central control board, and the control valve stops the discharge work, thereby achieving the effect of quantitative discharge of adhesive. The adhesive after quantitative discharge is temporarily stored in the receiving bin 35. At this time, by starting the discharge motor 31, the output shaft of the discharge motor 31 drives the receiving tray 34 on the clamping sleeve 33 to rotate through the clamping shaft 32, and the receiving tray 34 drives the adhesive material as a whole to be transported through the receiving bin 35. When the receiving bin 35 rotates to the discharge bin 37, the adhesive is discharged from the discharge bin 37 into the reaction bin 1, further completing the adhesive feeding work after quantitative weighing. When the unloading motor 31 is working, the weighing sensor in the weighing base 38 stops weighing.

[0031] During the unloading of the adhesive storage bin 4, the weighing base 38 will move downward as a whole according to the amount of adhesive unloaded while weighing. The greater the amount of adhesive, the longer the weighing base 38 moves downward. When the weighing base 38 moves downward, its bottom end drives the frame rod 561 to move through the bent rod 562. During the downward movement, the bent rod 562 exerts a force on the frame rod 561. The frame rod 561 converts the linear downward force into a rotational force and drives the contact head 52 to rotate. The contact head 52 drives the touch plates 53 at different positions thereon to contact the metal plate 55 according to different rotation angles. The touch plates 53 contact the metal plate 55 when they contact the metal plate. An electrical signal will be generated behind the plate 55, and the position of the touch plate 53 on the contact head 52 that contacts the metal plate 55 will also change due to the change in the rotation angle. Different touch plates 53 generate different electrical signals. The central control board determines the amount of adhesive fed according to different electrical signals, and controls the stirring motor to perform corresponding power work according to the electrical signals. The greater the amount of adhesive added, the longer the downward distance of the curved rod 562, that is, the greater the rotation angle of the contact head 52, the greater the power of the hollow plate to control the operation of the stirring motor, thereby achieving the effect that the reaction chamber 1 can control the stirring rate of the stirring motor according to the amount of adhesive added.
