Description

Technical Field

[0001] The present invention relates to the field of automated production of hot melt adhesives, and in particular to automated production and processing equipment and a processing method for hot melt adhesives. Background Art

[0002] Hot melt adhesive is an environmentally friendly adhesive that changes its physical state as the temperature changes within a certain range. When producing hot melt adhesive, it is first necessary to heat the raw materials such as resin, tackifier and filler into a reactor for heating and mixing, and then extrude and cool to form according to usage requirements, so as to facilitate the transportation and sales of hot melt adhesive products. Among them, hot melt glue sticks are widely used in plastics, wood, toys and other fields as a common hot melt adhesive. However, when hot melt glue sticks are produced, they are extruded by the extruder and enter the cooling pool at an inclined angle, which will cause the hot melt glue sticks to bend after forming. In order to improve the packaging efficiency of hot melt glue sticks, the hot melt glue sticks will be segmented by a cutting machine after cooling and forming, and then directly packed and packaged. However, the hot melt glue sticks segmented by the cutting machine are relatively messy when packaged, and need to be manually sorted and packed, which reduces the efficiency of packing.

[0032] In order to make the technical means, creative features, objectives and effects achieved by the embodiments of the present application easy to understand, the embodiments of the present application are further explained below in combination with diagrams and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the embodiments of the present application and are not used to limit the embodiments of the present application.

[0033] according to Figures 1 to 8 As shown, an automated production and processing equipment for hot melt adhesive comprises a box body 1, an extruder 2 is arranged at the front end of the box body 1, an extruder 2 is fixedly connected to an extrusion head 21, the extrusion head 21 is fixedly connected to the surface of the box body 1, a segmentation mechanism 5 is fixedly connected to the rear end of the box body 1, a traction mechanism 3 for pulling the hot melt adhesive to the segmentation mechanism 5 for cutting and segmenting after extruding the hot melt adhesive is fixedly connected inside the box body 1, a first driving mechanism 4 is fixedly connected to one side of the box body 1, the output ends of the first driving mechanism 4 are respectively connected to the traction mechanism 3 and the segmentation mechanism 5, cooling mechanisms 10 for cooling the hot melt adhesive sticks are respectively fixedly connected to the surface of the box body 1 on both sides of the traction mechanism 3, a material receiving hopper 6 for receiving the hot melt adhesive sticks is fixedly connected to the surface of the box body 1 at the outlet position of the segmentation mechanism 5, a metering mechanism 8 for quantitative feeding is arranged at the discharge port of the material receiving hopper 6, a conveying mechanism 7 is arranged at the bottom of the material receiving hopper 6, and a second driving mechanism 9 is connected between the conveying mechanism 7 and the metering mechanism 8.

[0034] In a specific implementation, one end of the extruder 2 can be fixedly connected to a reactor for producing hot melt adhesive, and the extrusion end of the extruder 2 is fixedly connected to an extrusion head 21. The extrusion head 21 can be cylindrical or directional according to the production requirements of the hot melt adhesive. After the hot melt adhesive is plastically extruded through the extrusion head 21, it is pulled toward the segmentation mechanism 5 through the pulling mechanism 3. At this time, the horizontal height of the extrusion head 21 is consistent with the height of the pulling part in the pulling mechanism 3, thereby ensuring that the hot melt adhesive can be pulled and moved horizontally after extrusion. At the same time, during this period, the extruded hot melt adhesive is cooled and cooled by the cooling mechanism 10, and the hot melt adhesive is further plasticized. After the hot melt adhesive passes through the pulling mechanism 10, When the guiding mechanism 3 is pulled to the segmenting mechanism 5, the hot melt glue is continuously cut into segments according to the use requirements, and then the cut hot melt glue sticks fall into the receiving hopper 6. The receiving hopper 6 can be set to a V shape, and a discharge port is opened at the bottom of the receiving hopper 6. The hot melt glue sticks are collected by the receiving hopper 6 and slide into the discharge port in turn. The discharge port is continuously closed and opened by the metering mechanism 8, so that the hot melt glue sticks can be discharged according to the moving interval of the metering plate 81 in the metering mechanism 8. The conveying mechanism 7 can transport the sorted hot melt glue sticks to the packaging process, avoiding the messy packaging of the hot melt glue sticks and improving the packaging efficiency.

[0035] Furthermore, the traction mechanism 3 includes two sheave groups and two first synchronous belts 33. The sheave group includes two sheaves 31 with opposite rotation directions. The two sheaves 31 are connected to the housing 1 in rotation from top to bottom in sequence. One side of the two sheaves 31 is coaxially fixedly connected with a first synchronous wheel 32. A first synchronous belt 33 is commonly sleeved between the two corresponding first synchronous wheels 32 on the left and right. A plurality of tooth blocks are provided in the radial direction of the first synchronous wheel 32, and a plurality of tooth grooves are provided on the inner side of the first synchronous belt 33. The tooth blocks are meshed with the tooth grooves. The outer sides of the two sheaves 31 in the left sheave group are coaxially fixedly connected with first bevel gears 34, and the first bevel gears 34 are respectively meshed with the first driving mechanism 4.

[0036] During specific implementation, the two sheave groups are respectively distributed in the box body 1 on the left and right, and a plurality of columns 11 corresponding to the sheave 31 are vertically arranged in the box body 1, and the sheave 31 is respectively rotatably arranged inside the box body 1 through the columns 11, and a plurality of first synchronous wheels 32 coaxially arranged with the sheave 31 are respectively rotatably connected on the columns 11 outside the sheave 31, and a first synchronous belt 33 is respectively sleeved on the first synchronous wheels 32 corresponding to the left and right sides, wherein the first synchronous wheels 32 in the left sheave group are respectively coaxially fixedly connected with the first bevel gear 34 on the outside, and the first bevel gear 34 is meshed with the first driving mechanism 4, and the first bevel gear 34 is driven to rotate by the first driving mechanism 4, and the first bevel gear 34 drives the two first synchronous wheels 32 on the left side to rotate about the axis, and the two rotating first synchronous wheels 32 drive the two first synchronous wheels 3 on the right side again through the first synchronous belt 33. 2 is rotated about the axis, and the corresponding groove wheel 31 is driven to rotate through the first synchronous wheel 32. The two groove wheels 31 distributed up and down in each groove wheel group are controlled by the first driving mechanism 4 to rotate in the opposite direction, so that the hot melt adhesive is pulled and moved from the gap between the two groove wheels 31 distributed up and down, and the horizontal height of the gap between the two groove wheels 31 is consistent with the horizontal height of the extruder 21, so that the hot melt adhesive can be horizontally pulled to the segmentation mechanism 5 through the traction mechanism 3 when it is extruded from the extruder 21, so that the hot melt adhesive is prevented from bending during cooling, and the molding efficiency of the hot melt adhesive stick is improved. The tooth grooves on the inner side of the first synchronous belt and the tooth blocks on the first synchronous wheel are meshed with each other. The transmission force of the first synchronous belt 33 and the first synchronous wheel 32 is increased through the cooperation of the tooth blocks and the tooth grooves, and the friction force between the first synchronous wheel 32 and the first synchronous belt 33 is increased, so as to improve the traction stability of the traction mechanism 3.

[0037] Furthermore, the segmentation mechanism 5 includes a segmentation base 51 and a segmentation cutter head 52. The segmentation base 51 is fixedly connected to the box body 1. The surface of the segmentation base 51 is provided with through holes 511 with openings at both ends for accommodating hot melt glue sticks. The top end of the segmentation cutter head 52 is rotatably connected to a reciprocating mechanism, which controls the segmentation cutter head 52 to vertically reciprocate in the segmentation base 51.

[0038] During specific implementation, the segmented base 51 is fixedly installed at the rear end of the box body 1, and the hot melt glue stick is moved from one end of the segmented base 51 to the other end through the through hole 511 by the traction mechanism 3. At this time, the segmented cutter head 52 is controlled by the reciprocating mechanism to continuously slide up and down vertically on the segmented base 51, thereby segmenting the hot melt glue stick.

[0039] Furthermore, the reciprocating mechanism includes an inner gear ring 55 and a second connecting rod 56, the inner ring is fixedly connected to the surface of the casing 1, the inner gear ring 55 is rotatably connected to one side of the upper end of the second connecting rod 56, the bottom end of the second connecting rod 56 is fixedly connected to a planetary gear 54, the planetary gear 54 is rotatably connected to the first connecting rod 53 non-coaxially, the other end of the first connecting rod 53 is hinged to the segmented cutter head 52, the other side of the upper end of the second connecting rod 56 is coaxially fixedly connected to a worm gear 57, a worm 58 is meshed with the bottom of the worm gear 57, both ends of the worm 58 are rotatably connected to the surface of the casing 1, and a third synchronous wheel 59 meshing with the first drive mechanism 4 is radially sleeved on the worm 58.

[0040] During specific implementation, first fixed blocks 581 are rotatably provided at both ends of the worm 58. The worm 58 is fixedly connected to the housing 1 through the first fixed blocks 581 at both ends. The third synchronous wheel 59 sleeved on the worm 58 is controlled by the first driving mechanism 4 to rotate around the axis. Since the third synchronous wheel 59 is fixedly connected to the worm 58 coaxially, the third synchronous wheel 59 drives the worm 58 to rotate around the axis. The rotating worm 58 drives the worm wheel 57 to rotate. The rotating worm wheel 57 controls the third connecting rod 83 to rotate around the axis of the worm wheel 57. The rotating third connecting rod 83 drives the planetary gear 54 rotatably connected on the other side to perform a circular motion in the inner gear ring 55. The planetary gear 54 performing a circular motion drives the planetary gear 54 connected to the planetary gear 54 to perform a circular motion. The second connecting rod 56, which is non-coaxially fixedly connected to the gear 54, makes an elliptical movement. Since the segmented cutter head 52 can only make vertical movement due to the limit setting of the segmented base 51, the segmented cutter head 52 hinged at the bottom end of the second connecting rod 56 is driven to make vertical reciprocating movement on the segmented base 51 when the second connecting rod 56 makes an elliptical movement. When the segmented cutter head 52 moves downward, the unsegmented hot melt adhesive is squeezed to achieve segmented processing of the hot melt adhesive. When the segmented cutter head 52 moves upward, the hot melt adhesive is continued to be pulled toward the rear end of the device by the traction machine of the traction mechanism 3, and then the segmented cutter head 52 moves downward again to extrude and segment the hot melt adhesive. The hot melt adhesive is segmented by the vertical reciprocating movement of the segmented cutter head 52. At the same time, since the through hole 511 on the segmented base 51 is respectively consistent with the horizontal height of the gap between the two groove wheels 31 and the extruder 21, it can be ensured that the horizontal heights of the two ends of the hot melt adhesive are consistent during segmentation, further avoiding the hot melt adhesive stick from bending during processing.

[0041] Further, the first drive mechanism 4 includes a first drive motor 41, the first drive motor 41 is fixedly connected to the housing 1, a second synchronous wheel 42 is coaxially fixedly connected to the output end of the first drive motor 41, a second synchronous belt 43 is jointly sleeved on the surface of the second synchronous wheel 42 and the third synchronous wheel 59, a second bevel gear 44 is coaxially fixedly connected to one side of the second synchronous wheel 42, a third bevel gear 46 is meshed with one side of the second bevel gear 44, the third bevel gear 46 is coaxially fixedly connected to the transmission shaft 45, the top and bottom ends of the transmission shaft 45 are respectively coaxially fixedly connected to the fourth bevel gear 47, and the fourth bevel gear 47 are respectively meshed with the first bevel gear 34.

[0042] During specific implementation, the transmission shaft 45 is rotatably connected with the second fixed block 48 in the radial direction, and the second fixed block 48 is fixedly installed on the column 11. When the first drive motor 41 is running, it drives the second synchronous wheel 42 to rotate around the axis. The rotating second synchronous wheel 42 drives the third synchronous wheel 59 to rotate through the second synchronous belt 43. The third synchronous wheel 59 controls the worm 58 to rotate around the axis, so that the segmented cutter head 52 is controlled by the reciprocating mechanism to perform vertical reciprocating motion. When the second synchronous wheel 42 rotates around the axis, it synchronously drives the second bevel gear 44 to rotate. The rotating second bevel gear 44 drives the meshing third bevel gear 46 to rotate around the axis. The rotating third bevel gear 46 drives the transmission shaft 45 to rotate around the axis. The transmission shaft 45 drives the two third bevel gears 46 at the top and bottom to rotate coaxially. The rotation of the third bevel gear 46 again drives the first bevel gear 34 meshing with the third bevel gear 46 to rotate about the axis. Subsequently, the rotation of the first bevel gear 34 drives the first synchronous wheel 32 to rotate about the axis, thereby finally realizing the rotation of multiple groove wheels 31. When the transmission shaft 45 rotates, the two third bevel gears 46 at the top and bottom rotate in opposite directions, thereby controlling the top two groove wheels 31 and the bottom two groove wheels 31 in the left and right groove wheel groups to rotate in opposite directions. The first driving mechanism 4 can provide driving force for the reciprocating mechanism and the traction mechanism 3 at the same time, effectively reducing the cost of the device and increasing the practicality of the first driving motor 41.

[0043] Furthermore, the conveying mechanism 7 includes a frame 71, an active roller 73 and a plurality of driven rollers 74. The active roller 73 and the plurality of driven rollers 74 are rotatably connected in the frame 71. One end of the active roller 73 is connected to the second driving mechanism 9. A conveyor belt 72 is commonly sleeved on the active roller 73 and the plurality of driven rollers 74. A groove 721 is provided on the surface of the conveyor belt 72 for arranging the hot melt glue sticks neatly.

[0044] During specific implementation, the active roller 73 is controlled by the second driving mechanism 9 to perform axial rotation movement. When the active roller 73 rotates, multiple driven rollers 74 are driven to rotate through the transmission belt, thereby realizing the transmission function of the transmission belt. When the hot melt glue stick falls onto the transmission belt, it can fall into the groove 721 on the surface of the conveyor belt 72, so that the hot melt glue stick will not roll randomly when being conveyed by the conveyor belt 72, which is convenient for workers to organize and pack the hot melt glue sticks, thereby improving the efficiency of workers in packing the hot melt glue sticks.

[0045] Furthermore, the metering mechanism 8 includes a metering plate 81 horizontally slidably arranged at the discharge port of the receiving hopper 6, one side of the metering plate 81 is fixedly connected to a connecting shaft 82, the other end of the connecting shaft 82 is rotatably connected to a third connecting rod 83, and the other end of the third connecting rod 83 is fixedly connected to the second driving mechanism 9.

[0046] During specific implementation, the fixing plate 81 is horizontally slidably connected to the discharge port of the receiving hopper 6, and the other end of the fixing plate 81 is fixedly connected to the second driving mechanism 9 through the connecting shaft 82 and the third connecting rod 83. The fixing plate 81 is controlled by the second driving mechanism 9 to continuously slide back and forth horizontally at the discharge port. When the fixing plate 81 slides into the discharge port, the discharge opening is closed, so that the hot-melt glue stick cannot continue to fall onto the conveyor belt 72. When the fixing plate 81 slides out of the discharge port, the discharge port is opened, so that the hot-melt glue stick can continue to fall onto the conveyor belt 72. The horizontal reciprocating motion of the fixing plate 81 is used to achieve delayed discharge of the hot-melt glue stick, thereby preventing multiple hot-melt glue sticks from falling onto the conveyor belt 72 at the same time, thereby causing the hot-melt glue sticks to stack continuously and cause chaos when being transported on the conveyor belt 72, thereby improving the transmission efficiency of the conveyor belt 72.

[0047] Furthermore, the second drive mechanism 9 includes two fourth synchronous wheels 94 and a second drive motor 91, the two fourth synchronous wheels 94 are respectively coaxially fixedly connected to the active roller 73 and the driven roller 74 on one side of the active roller 73, a third synchronous belt 95 is sleeved on the two fourth synchronous wheels 94, the outer side of the fourth synchronous wheel 94 on one side of the active roller 73 is coaxially fixedly connected to the second spur gear 93, the output end of the second drive motor 91 is fixedly connected to the first spur gear 92, and the first spur gear 92 is meshed with the second spur gear 93.

[0048] During specific implementation, the second driving motor 91 drives the first spur gear 92 to rotate when running, and the rotating first spur gear 92 drives the second spur gear 93 meshing with the first spur gear 92 to rotate, and the rotation of the second spur gear 93 controls the active roller 73 to rotate about the axis, and then the rotation of the active roller 73 drives the multiple driven rollers 74 and the conveyor belt 72 sleeved on the surfaces of the active roller 73 and the multiple driven rollers 74 to transmit. At the same time, when the second spur gear 93 rotates, it synchronously drives a fourth synchronous wheel 94 fixedly connected to the second spur gear 93 and the active roller 73 coaxially to rotate about the axis, and the fourth synchronous wheel fixedly connected to the active roller 73 coaxially 94 synchronously drives a fourth synchronous wheel 94 coaxially fixedly connected to a driven roller 74 on one side of the active roller 73 to rotate about the axis through the third synchronous belt 95. At this time, one end of the third connecting rod 83 is non-coaxially connected to the fourth synchronous wheel 94 for rotation. Therefore, when the fourth synchronous wheel 94 rotates, the third connecting rod 83 drives the fixing plate 81 to make horizontal reciprocating motion at the discharge port of the receiving hopper 6. The second drive motor 91 is used to control the quantitative mechanism and the conveying mechanism 7 respectively, which can effectively reduce the cost of the device. At the same time, the cooperation of the quantitative mechanism and the conveying mechanism 7 can effectively avoid confusion of the hot-melt glue sticks before packing, so that workers can pack the hot-melt glue sticks more conveniently.

[0049] Furthermore, the cooling mechanism 10 includes a water pump 101 and a spray port 104. The water pump 101 is fixedly arranged at the bottom of the box body 1. A plurality of water inlets 102 are arranged around the water pump 101. The water outlet of the water pump 101 is fixedly connected to a water pipe 103. The other end of the water pipe 103 is fixedly connected to the spray port 104. The spray port 104 is fixedly connected to the box body 1.

[0050] During specific implementation, the water pump 101 is fixedly connected to the bottom of the box body 1, wherein the space at the bottom of the box body 1 can be used to collect water for cooling the hot melt glue stick. Specifically, a certain amount of clean water is added to the box body 1 before the device starts, and then the water pump 101 is started. The clean water in the box body 1 is transported to the spray port 104 through the water pipe 103 by the water pump 101, and the clean water is sprayed to the unsegmented hot melt glue through the spray port 104 to achieve cooling of the hot melt glue, so that the hot melt glue can quickly solidify plasticity.
