Technical Field

[0001] The invention relates to the technical field of processing devices, in particular to a hot air filling and sealing device. Background Art

[0002] In order to improve the filling efficiency of hoses, some companies have developed automated filling and sealing devices. For example, the hose is rotated to various functional mechanisms around the turntable through a turntable mechanism, and then each functional mechanism performs predetermined actions on the hose. However, there are inconsistencies in the length of the hose under different requirements. When the same filling and sealing device is used to deal with a hose of another size, the lifting stroke of each functional mechanism needs to be adjusted in advance, which is troublesome and inefficient and needs to be improved. Summary of the invention

[0003] To solve at least one of the above technical defects, the present invention provides the following technical solutions:

[0004] The present application document discloses a filling and sealing device, comprising a turntable mechanism, a cup holder for accommodating corresponding workpieces, a filling component, an upper tube component, a sealing component, a cutter component, and a discharging component. The cup holder is arranged on a turntable in the turntable mechanism, and the upper tube component, the filling component, the sealing component, the cutter component, and the discharging component are arranged at intervals around the turntable mechanism. During the rotation of the turntable, the cup holder is sent to the working position of the upper tube component, the filling component, the sealing component, the cutter component, and the discharging component; the upper tube component is used to transport the corresponding workpiece to the cup holder; the filling component is used to fill the workpiece in the cup holder with materials; the sealing component is used to seal the workpiece in the cup holder; the cutter component is used to cut off a predetermined part of the workpiece in the cup holder; the discharging component is used to take out the workpiece in the cup holder, and the position adjustment mechanism is also included. The position adjustment mechanism comprises a bracket, a mounting plate, and a longitudinal lifting mechanism. The mounting plate is connected to the bracket by the longitudinal lifting mechanism, and the longitudinal height of the mounting plate is adjusted by the longitudinal lifting mechanism. At least one of the cutter component, the filling component, and the sealing component is arranged on the mounting plate.

[0005] When filling and sealing workpieces of different lengths (such as hoses), the longitudinal height of the sealing component, filling component, and cutting knife component can be directly adjusted through the longitudinal lifting mechanism, so that the previous control program can be directly used to fill and seal the workpieces, reducing tedious adjustment time and helping to improve efficiency.

[0006] Furthermore, the cutter assembly and the tail sealing assembly both include a crank arm clamping mechanism, which includes a first lifting mechanism, a fixed seat, a crank arm, a connecting rod, a mounting seat, and a slider.

A guide surface for guiding the workpiece to tip toward the discharging chute is arranged on the guide plate. The telescopic mechanism three is below the moving path of the cup holder, and the moving end of the telescopic mechanism three moves upward to push the workpiece at the cup holder to move upward. During the upward movement of the workpiece, it passes through the space between the top block and the discharging chute and abuts against the upper guide plate. With the support of the telescopic mechanism three, the guidance of the guide plate, and the support of the top block, the workpiece is tipped toward the discharging chute, and the material can be discharged stably.

DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] like Figure 1-Figure 3As shown, in this example, the filling and sealing device includes a turntable mechanism 5, a cup holder 6 for placing the corresponding workpiece, a filling component 8, an upper tube component 4, a sealing component, a cutter component 11, and a discharge component 12, wherein the turntable mechanism can be selected from the market according to the demand. The cup holder 6 is installed at the top surface of the turntable in the turntable mechanism 5, such as a cylindrical cup holder, which can be inserted into a hose-like workpiece. The upper tube component 4, the filling component 8, the sealing component, the cutter component 11, and the discharge component 12 are installed at intervals around the turntable mechanism 5. During the rotation of the turntable, the cup holder 6 is sent to the station of the upper tube component 4, the filling component 8, the sealing component, the cutter component 11, and the discharge component 12. When the upper tube component 4 is at the station, the upper tube component 4 is used to transport the corresponding hose to the cup holder 6. When the filling component 8 is at the station, the filling component 8 is used to fill the hose in the cup holder 6 with materials. When the sealing component is at the station, the sealing component is used to seal the hose in the cup holder 6. When the cutter assembly 11 is used, the cutter assembly 11 is used to cut off the predetermined part of the workpiece in the cup holder 6. At the discharging station, the discharging assembly 12 is used to take out the workpiece in the cup holder 6. For this purpose, a benchmarking assembly 7 can be added. The benchmarking assembly 7 positions the hose in the cup holder that has completed the tube mounting process. According to the needs, a mechanism for horizontal and vertical positioning of tube-type workpieces can be selected from the market as a benchmarking assembly. For example, in this example, only the hose in the cup holder is pressed down by the telescopic cylinder for longitudinal positioning. For example, the hose in the cup holder moves with the turntable to the bottom of the telescopic cylinder in the benchmarking assembly, and the moving end of the telescopic cylinder moves down to press the hose to the desired position for longitudinal positioning. A pressure block or pressure plate of a desired shape can also be installed at the moving end of the telescopic cylinder. In order to improve the orderliness of the operation, it is preferred as follows Figure 1-Figure 3 As shown, the upper tube assembly 4, the marking assembly 7, the filling assembly 8, the tail sealing assembly, the cutter assembly 11, and the discharging assembly 12 are arranged in sequence along the circumference of the turntable, which helps to improve efficiency.

[0037] In order to facilitate transportation and placement, a base 1 is added in this example, and a turntable mechanism 5, an upper tube assembly 4, a marking assembly 7, a filling assembly 8, a tail sealing assembly, a cutter assembly 11, a discharging assembly 12, etc. are centrally placed on the base 1. A sheet metal frame 2 can also be added, such as Figure 1-Figure 3 As shown, the turntable mechanism 5, the marking assembly 7, the filling assembly 8, the sealing assembly, and the cutter assembly 11 are basically in the cavity surrounded by the sheet metal frame 2, and the discharge assembly 12 and the upper tube assembly 4 are partially in the sheet metal frame 2. A control terminal 13 can also be added, such as a fixed control terminal 13 on the sheet metal frame, and the control terminal is connected to the turntable mechanism, the upper tube assembly, the marking assembly, the filling assembly, the sealing assembly, the cutter assembly, the discharge assembly, etc., so as to facilitate the control of each functional mechanism to perform corresponding actions through a preset program.

[0038] In order to improve efficiency, a positioning mechanism 3 is added in this example, wherein the positioning mechanism 3 includes a bracket 300, a mounting plate 301 and a longitudinal lifting mechanism 302. The mounting plate 301 and the bracket 300 are connected via the longitudinal lifting mechanism 302, and the longitudinal height of the mounting plate 301 is adjusted by the longitudinal lifting mechanism 302. At least one of the cutter assembly 11, the filling assembly 8 and the tail sealing assembly is placed on the mounting plate. The mounting plate can be selected to be single or multiple according to the needs, such as Figure 1 , Figure 3 As shown, in this example, there are two mounting plates 301, wherein the cutter assembly 11 is fixed on one mounting plate 301, and the tail sealing assembly, the filling assembly 8, and the marking assembly 7 are on the other mounting plate 301. The longitudinal lifting mechanism 302 can be selected from the market according to demand and has a longitudinal adjustment function. Common ones include screw lifting type, telescopic cylinder type, gear rack lifting type, etc. In this example, the screw lifting type is used as an example for demonstration. For example, the screw is pivotally connected to the bracket 300, and the nut on the screw is fixed to the mounting plate 301. The mounting plate 301 can be guided and moved by the guide column on the base, and the nut is raised and lowered by rotating the screw, which correspondingly raises and lowers the mounting plate. The power to drive the screw is a motor, of course, it can also be used Figure 1-Figure 3 In the manual type shown, a hand wheel is installed at the end of the screw rod extending to the top surface of the bracket 300, and the hand wheel can be manually driven to rotate to adjust the height of the mounting plate. When the batch of filled hoses is changed and the hose length is different, the longitudinal height of the filling component, the cutter component, etc. can be simply adjusted to adapt to the processing of the hose of the new length. There is no need to make complex and cumbersome parameter adjustments to the filling component, the cutter component, the tail sealing component, etc., which helps to improve efficiency. To simplify the structure, the bracket is a semi-ring shape placed horizontally, and the bracket is fixed to the base through a guide column, and the guide column guides the movement of the mounting plate in the longitudinal direction.

[0039] In this example, the cutter assembly 11 and the tail sealing assembly both include a curved arm clamping mechanism 110, such as Figure 7 As shown, the cutter assembly 11 includes a curved arm clamping mechanism 110 and a cutter 111, wherein the curved arm clamping mechanism 110 includes a first lifting mechanism 1112, a fixed seat 1111, a curved arm 1115, a connecting rod 1114, a mounting seat 1113, and a slider 1116. The fixed seat 1111 is installed on the corresponding mounting plate 301, and the first lifting mechanism 1112 is fixed on the fixed seat 1111. The first lifting mechanism 1112 is a mechanism that can move the connected object in the longitudinal direction, such as a telescopic cylinder, a gear rack lifting, a screw lifting, etc. In this example, a telescopic cylinder is used as an example for demonstration.

[0040] The first lifting mechanism 1112 is fixed with a mounting seat 1113 at the moving end, and connecting rods 1114 are respectively hinged at the relative positions on the mounting seat 1113, and the other end of the connecting rod 1114 is connected to the head end of the curved arm 1115. Specifically, the head end of the connecting rod 1114 is hinged to the side position of the mounting seat 1113, the tail end of the connecting rod 1114 is hinged to the head end of the curved arm 1115, and the middle of the curved arm 1115 is hinged to the fixed seat 1111. Preferably, the mounting seat 1113 is slidably connected to the fixed seat 1111 to help improve the stability of movement.

[0041] The fixed seat 1111 is relatively slidably connected to the slider 1116 and the tail end of the crank arm 1115 is formed with waist holes 1117, and the waist holes 1117 are hinged with the corresponding slider 1116 through the pivot. In this example, the cutter 111 is installed at the end faces of the two sliders 1116 facing each other. When in use, if the first lifting mechanism 1112 moves the mounting seat 1113 up and down in the longitudinal direction, the slider 1116 is moved toward or away from each other under the transmission of the connecting rod 1114 and the crank arm 1115. When the two sliders move toward each other, the clamping action is performed, and the cutter is used to cut the end of the hose extending between the sliders to cut off the unnecessary part. When the two sliders move away from each other, the loosening action is performed to facilitate the end of the hose to be separated between the two sliders or from the two sliders.

[0042] The configuration of the fixing seat can be selected according to the needs, preferably as follows Figure 7 Configuration, specifically, the main body of the fixed seat 1111 is rectangular, the first lifting mechanism 1112 is installed at the top of the main body, a mounting hole is formed in the middle of the main body and the mounting seat 1113 is located at the mounting hole, and both sides of the bottom of the main body are provided with outwardly protruding parts, namely, convex parts, the bottom surface of the convex part is slidably connected to the slider 1116, and the middle of the curved arm 1115 is hinged at the side of the convex part.

[0043] For the tail sealing component, such as the hot air type, specifically, the tail sealing component includes a hot air mechanism, a hot pressing mechanism, such as Figure 1 , Figure 2 , Figure 3 As shown, the hot air mechanism 9 is used to heat the predetermined position of the workpiece at the cup seat, and commonly includes a wind tube, which is connected to an external heating mechanism, or the wind tube itself is a heatable blowing type, similar to a hair dryer. When the cup seat at the turntable corresponds to the wind tube, hot air is blown downward from the wind tube to heat and soften the end of the hose.

[0044] The hot pressing mechanism 10 includes a curved arm clamping mechanism and a hot pressing mold. The curved arm clamping mechanism is the above-mentioned structure. The corresponding hot pressing mold can be installed at the facing surfaces of the two sliders. When in use, the turntable mechanism places the hose after the action of hot air between the two parts of the hot pressing mold, and the two sliders move toward each other. The hot pressing mold cooperates to clamp the softened end of the hose to make it bonded to complete the tail sealing.

[0045] In addition, the sealing component can also be ultrasonically welded, such as Figure 8 As shown, the sealing assembly specifically includes an ultrasonic mechanism and a curved arm clamping mechanism 110. The curved arm clamping mechanism is the above-mentioned structure. The ultrasonic mechanism includes a matching ultrasonic mold 112. The ultrasonic mold 112 that matches and is used for welding is installed on the surfaces facing each other of the two sliders 1116 in the curved arm clamping mechanism 110. The die head in the ultrasonic mold is connected to the ultrasonic body placed in the base. When the end of the filled hose moves with the turntable to between the ultrasonic molds, the two sliders move toward each other, and then the end of the hose is welded and sealed by the ultrasonic mold.

[0046] The two types of tail sealing components can be installed either one or both on the mounting plate, and the tail sealing action can be performed one by one according to different usage requirements.

[0047] For the filling component 8, such as the common screw quantitative feeding mechanism in the market with the telescopic cylinder lifting type, when the hose in the cup holder moves with the turntable to below the discharge port of the feeding mechanism, the telescopic cylinder moves the feeding mechanism downward to make its discharge port plug into the cavity at the end of the hose, and the storage barrel containing the material can be placed on the base, such as Figure 1 , Figure 2 , Figure 3 As shown, the material storage barrel 81 is connected to the feed port of the feeding mechanism.

[0048] For the discharging component, a robot or other mechanism can be selected according to the needs to pull out the hose in the cup holder. Figure 1 , Figure 2 , Figure 3 In the structure shown, the discharge assembly 12 includes a support frame 121, a top block 124, a guide plate 122, a discharge chute 126, and a telescopic mechanism 125. The support frame 121 is fixed on the bracket 300, the discharge chute 126 is fixed to the base 1, and the guide plate 122 is placed above the entrance of the discharge chute 126, and the top block 124 is placed below the guide plate 122. The top block 124 and the guide plate 122 are fixed to the longitudinal frame part of the support frame 121. The guide surface 123 formed on the guide plate 122 is used to guide the workpiece to fall toward the discharge chute 126. Figure 3 As shown, the guide plate 122 is arc-shaped, and faces the bottom surface of the discharge chute, namely the guide surface 123 .

[0049] The telescopic mechanism three 125 is like a telescopic cylinder, which is located at the base 1 below the moving path of the cup holder. When the cup holder 6 is above the telescopic mechanism three 125, the moving end of the telescopic mechanism three 125 moves upward to push the hose at the cup holder 6 to move upward. During the upward movement of the workpiece, it passes through the space between the top block 124 and the discharge chute 126 and abuts against the upper guide plate 122. When the telescopic mechanism three 125 continues to push up, under the guidance of the guide surface 123 of the guide plate 122, the hose tilts toward the discharge chute 126, and the synchronous top block abuts against the hose body under the guide plate to form a support, which cooperates to make the workpiece tip toward the discharge chute, and then slides down from the discharge chute to complete the unloading.

[0050] For the upper tube assembly, you can choose a robot or other loading method according to your needs. Figure 5 , Figure 6 The configuration shown specifically includes a hopper 40 for accommodating workpieces, a connecting seat 47, a flipping mechanism 52, a pipe seat 42, and a telescopic mechanism 44, wherein a groove 43 for inserting a hose is formed on the pipe seat 42. The output end of the flipping mechanism 52 is connected to the pipe seat 42 and rotates the pipe seat 42 in the longitudinal plane. Preferably, a fixing block 45 is installed at the output end of the flipping mechanism 52, and the pipe seat 42 is installed on the fixing block 45, so as to facilitate docking and adjusting the position of the pipe seat. The fixing block 45 is L-shaped, and the longitudinal part of the fixing block 45 fixes the pipe seat 42, and the transverse part thereof is fixed to the output end of the flipping mechanism 52. The flipping mechanism 52 is a flipping cylinder, and the groove 43 on the pipe seat 42 is reciprocatedly switched between the transverse state and the longitudinal state through the flipping mechanism 52.

[0051] A connecting seat 47 is arranged between the pipe seat 42 and the outlet of the hopper 40, and a material channel 471 extending obliquely is formed on the connecting seat 47, the head end inlet of the material channel 471 is connected to the outlet 401 of the hopper, and the groove 43 on the pipe seat 42 is located below the tail end outlet of the material channel 471. The telescopic mechanism 1 44 is located above the groove 43 in the longitudinal state, and the moving end of the telescopic mechanism 1 44 moves downward to push the hose in the groove 43 to the cup seat below.

[0052] In order to facilitate the fixation of the connecting seat and other mechanisms, a fixing frame 51 is added in this example, the fixing frame 51 is fixed to the base 42, the connecting seat 47 is fixed on the fixing frame 51, the hopper 471 is fixed to the fixing frame 51 or the connecting seat, the flipping mechanism 52 is fixed to the fixing frame 51 below the connecting seat 47, and the telescopic mechanism 44 is connected to the fixing frame 51 and is located on the side of the connecting seat 47.

[0053] When in use, if the hopper is tilted or the bottom wall of the hopper cavity is tilted, the hose in the hopper can be better allowed to slide to the hopper outlet. The hopper can accommodate multiple hoses, and the hoses slide out of the hopper outlet 401 to the material channel, and then slide down along the material channel. The flip mechanism rotates the tube seat so that its groove is in a horizontal state, that is, a horizontal state, and the hose that slides out of the material channel slides into the groove in the horizontal state. Then the flip mechanism rotates the tube seat so that the groove changes from a horizontal state to a vertical state, that is, a vertical state. At this time, the moving end of the telescopic mechanism 1 is above the groove, and the moving end of the telescopic mechanism 1 moves downward to push the hose in the groove into the cup holder cavity. It is preferred to place a pressure block, a pressure plate, etc. at the moving end of the telescopic mechanism 1 to better press down the hose.

[0054] In addition, a limiting mechanism can be added, which includes a telescopic mechanism 2 50 and a baffle 49. The telescopic mechanism 2 is such as a telescopic cylinder, which is connected to the connecting seat 47 and is located above the material channel outlet. The baffle 49 is fixed at the moving end of the telescopic mechanism 2 50. When in use, the baffle 49 is moved back and forth longitudinally by the telescopic mechanism 2. The baffle 49 moves down into the material channel to limit the downward movement of the hose in the material channel. When the baffle moves up, the restriction on the downward movement of the hose along the material channel is released.

[0055] A pushing mechanism 41 may also be added, and the pushing mechanism 41 includes a driving mechanism 410, a connecting shaft, a connecting column 414, a connecting plate 413 and a fixed shaft 411. The driving mechanism is such as a driving motor, and its output end is connected to the connecting shaft, and the axial center lines of the two are on the same straight line. The connecting column 414 is radially fixed at the other end of the connecting shaft, and the top of the connecting column 414 is hinged to the waist hole formed at the connecting plate 413. The connecting plate 413 is fixed to the fixed shaft 411 at a position on one side of the hinge between the connecting column 414 and the connecting plate 413. The fixed shaft 411 is hinged on the connecting seat 47 and the fixed shaft 411 is above the material channel. The fixed shaft 411 is fixed with a push plate 412, and the push plate is such as a flat plate or Figure 5 , Figure 6 The trough shape shown.
