An automatic adhesive filling device

Abstract

The present application discloses an automatic adhesive filling device, which relates to the field of liquid filling technology, including a containing component, a glue delivery component, a diversion component, a filling component and a metering component, wherein the filling component includes a filling tube in an L-shaped structure. The present application adopts the coordination arrangement between the filling tube, the guide frame, the floating plate, the sliding tube and the proximity switch. During filling, the sliding tube slides down to push the floating plate into the packaging container. As the liquid level of the injected adhesive rises, the floating plate rises synchronously to push the sliding tube upward to contact the contact switch to close the electromagnetic valve, so that the filling head stops pouring adhesive into the packaging container. Since the length of the sliding tube is fixed, the liquid level of the adhesive poured into the packaging container is the same, thereby realizing quantitative filling of the adhesive, and avoiding as much as possible the current adhesive filling, which is mostly controlled manually, extracted by a glue pump, and measured by workers visually, which is not only inefficient, but also prone to problems such as inaccurate measurement and glue overflow caused by operating errors.

Description

Technical Field

[0001] The present application relates to the technical field of liquid filling, and in particular to an automatic adhesive filling device. Background Art

[0002] A class of organic or inorganic, natural or synthetic substances that can connect the same or two or more homogeneous or heterogeneous parts or materials together and have sufficient strength after curing are collectively called adhesives or bonding agents, adhesives, and are usually referred to as adhesives. After production, adhesives generally need to be filled in barrels or bottles for sale.

[0003] At present, most adhesive filling is controlled manually, with glue extraction machines used and workers visually measuring. This is not only inefficient, but also prone to problems such as inaccurate measurement and glue overflow caused by operational errors. Utility Model Content

[0004] The utility model aims to solve or at least alleviate the problem that most of the current adhesive filling is manually controlled, with glue extraction machines and workers visually measuring, which is not only inefficient but also prone to inaccurate measurement, glue overflow due to operating errors, and other problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An automatic adhesive filling device comprises a containing component, a glue delivery component, a flow distribution component, a filling component and a metering component. The filling component comprises a filling tube with an L-shaped structure. A filling head is fixedly connected to the bottom end of the filling tube. A guide frame is fixedly connected to the vertical section of the filling tube. A sliding tube which is slidably connected to the guide frame and has a floating plate fixedly connected to the bottom end is passed through the end of the guide frame away from the filling tube. A solenoid valve which is opposite to the top end of the sliding tube is installed on the horizontal section of the filling tube. A contact switch for controlling the opening or closing of the solenoid valve is fixedly connected to the lower surface of the solenoid valve.

[0007] By adopting the above technical solution, when using, the user first places the packaging container under the filling head. At this time, the slide tube slides down under the action of gravity to push the float plate to extend into the packaging container, so that the top of the slide tube is away from the contact switch, and the solenoid valve is in an open state. The user can turn on the peristaltic pump and inject the adhesive into the packaging container through the rubber delivery hose, the three-way pipe and the filling tube. Since the float plate has a small density, it can float on the surface of the adhesive. As the liquid level of the adhesive injected into the packaging container increases, the float plate rises synchronously under the action of buoyancy and pushes the slide tube to move vertically upward until the top of the slide tube contacts the contact switch, so that the contact switch starts to close the solenoid valve, so that the filling head stops pouring adhesive into the packaging container. Since the length of the slide tube is fixed, the liquid level of the adhesive poured into the packaging container is the same, thereby realizing quantitative filling of the adhesive, and trying to avoid the current adhesive filling, most of which is manually controlled, extracted by a glue pump, and measured by workers' visual measurement, which is not only inefficient, but also prone to problems such as inaccurate measurement and overflow caused by operating errors.

[0008] Optionally, the containing assembly includes a storage tank, a plurality of supporting legs are fixedly connected to the periphery of the bottom of the storage tank, and two lifting ears welded to the storage tank are symmetrically provided on both sides of the top of the storage tank.

[0009] By adopting the above technical solution, a storage tank is provided for storing adhesive, and supporting legs and lifting ears are provided, so that the user can stably support the storage tank on the ground at a suitable position through the supporting legs according to his own needs, or hang the storage tank to a high place through the lifting ears, which is convenient for the user to use.

[0010] Optionally, the glue delivery assembly includes a peristaltic pump fixedly connected to the bottom wall of the inner cavity of the storage tank, the output end of the peristaltic pump is fixedly connected to a glue delivery hose, and the end of the glue delivery hose away from the peristaltic pump passes through the side wall of the storage tank and is fixedly connected to the side wall of the storage tank.

[0011] By adopting the above technical solution, when the peristaltic pump is started, the adhesive in the storage tank can be introduced into the rubber delivery pipe through the peristaltic pump, and transferred along the rubber delivery pipe to the filling pipe for filling.

[0012] Optionally, the diversion assembly includes a tee installed on one end of the glue delivery hose away from the peristaltic pump, one discharge port of the tee is connected to a transmission pipe for delivering the adhesive to other production lines, and one end of the filling tube away from the filling head is fixedly connected to the other discharge port of the tee.

[0013] By adopting the above technical solution, a three-way pipe is set to divert the adhesive discharged from the rubber delivery pipe, so that the adhesive can be transferred to other production lines through the transmission pipe for use during the gap of glue filling, thereby improving work efficiency.

[0014] Optionally, an arc-shaped elbow is provided between the transmission pipe and the tee, the transmission pipe is fixedly connected to the tee via the elbow, and the height of one end of the transmission pipe connected to the elbow is higher than the height of one end of the elbow connected to the tee.

[0015] By adopting the above technical solution, when the solenoid valve is in the open state, since the height of the transmission tube is higher than the top height of the filling tube, the adhesive is discharged along the filling tube for filling under the action of gravity. When the packaging container is full and needs to be replaced, the solenoid valve is in the closed state. At this time, the adhesive cannot enter the filling tube. Under the subsequent pressure, the adhesive can enter the transmission tube through the bent tube, and the adhesive is transported to other production lines for use through the transmission tube during the filling gap.

[0016] Optionally, an adjusting rod is slidably connected to the top end of the sliding tube, and a limiting bolt threadedly connected to the sliding tube is provided on the side wall of the connecting end of the sliding tube and the adjusting rod.

[0017] By adopting the above technical solution, a sliding adjustment rod is connected on the top of the sliding tube so that the user can adjust the total length of the entire metering assembly by sliding the adjustment rod, thereby adjusting the liquid level of the adhesive filled inside the packaging container. When the adjustment is completed, the user can screw the limit bolt into the inside of the sliding tube to squeeze the adjustment rod to increase the friction between the adjustment rod and the inner wall of the sliding tube, thereby fixing the sliding tube and the adjustment rod relatively.

[0018] Optionally, the floating plate has a disc-shaped structure, and the buoyancy of the floating plate is greater than the total gravity of the sliding tube, the adjusting rod and the limiting bolt.

[0019] By adopting the above technical solution, the floating plate can float on the adhesive liquid surface under the action of its own buoyancy, thereby realizing automatic metering of the adhesive.

[0020] In summary, the beneficial effects of this application are as follows:

[0021] The present application achieves this by coordinating the structures such as the filling tube, the guide frame, the floating plate, the sliding tube and the proximity switch. During filling, the sliding tube slides down to push the floating plate into the packaging container. As the liquid level of the injected adhesive rises, the floating plate rises synchronously to push the sliding tube upward to contact the contact switch to close the solenoid valve, so that the filling head stops pouring adhesive into the packaging container. Since the length of the sliding tube is fixed, the liquid level of the adhesive poured into the packaging container is the same, thereby achieving quantitative filling of the adhesive and avoiding the current situation where most of the adhesive filling is manually controlled, extracted by a glue pump and measured by workers' visual inspection, which is not only inefficient, but also prone to problems such as inaccurate measurement and glue overflow caused by operating errors.

[0026] The following is combined with Figure 1-3 This application is described in further detail.

[0027] See also Figure 1-3 An automatic adhesive filling device includes a containing component for containing adhesive, a glue conveying component for guiding the adhesive out of the containing component, a diversion component, a filling component for quantitatively filling the adhesive, and a metering component.

[0028] The filling component includes a filling tube 9 with an L-shaped structure, and a filling head 10 is fixedly connected to the bottom end of the filling tube 9. The end of the filling tube 9 away from the filling head 10 is connected to the glue delivery component through a diversion component, so that the glue delivery component can transport the adhesive contained in the filling component to the inside of the filling tube 9 and pour it into the packaging container through the filling head 10.

[0029] A guide frame 11 is fixedly connected to the vertical section of the filling tube 9. A guide hole is provided at one end of the guide frame 11 away from the filling tube 9. A slide tube 12 is passed through the guide hole and is slidably connected to the guide frame 11 through the guide hole. A float plate 13 is fixedly connected to the bottom end. When the adhesive is filled, the float plate 13 and the filling head 10 extend together into the inner cavity of the packaging container. As the liquid level of the adhesive filled into the packaging container rises, the float plate 13 can move upward synchronously under the action of buoyancy, and push the slide tube 12 to move vertically upward along the guide hole.

[0030] The horizontal section of the filling tube 9 is provided with a solenoid valve 16 which is opposite to the top of the slide tube 12, and the lower surface of the solenoid valve 16 is fixedly connected with a contact switch 17 for controlling the opening or closing of the solenoid valve 16. When the floating plate 13 pushes the slide tube 12 to move vertically upward under the action of buoyancy until it contacts the contact switch 17, the contact switch 17 is activated to control the solenoid valve 16 which is electrically connected to the contact switch 17 to be closed, so that the filling head 10 stops pouring the adhesive into the packaging container. Since the length of the slide tube 12 is fixed, the liquid level of the adhesive poured into the packaging container is the same, thereby realizing quantitative filling of the adhesive.

[0031] Reference Figure 1 The storage assembly includes a storage tank 1, a plurality of supporting legs 2 are fixedly connected to the bottom periphery of the storage tank 1, and two lifting ears 3 welded to the storage tank 1 are symmetrically arranged on both sides of the top of the storage tank 1. The storage tank 1 is used to store adhesives, and the supporting legs 2 and the lifting ears 3 are provided, so that the user can stably support the storage tank 1 on the ground at a suitable position through the supporting legs 2 according to their own needs, and can also hang the storage tank 1 to a high place through the lifting ears 3, which is convenient for users to use.

[0032] Reference Figure 1 The glue delivery assembly includes a peristaltic pump 4 fixedly connected to the bottom wall of the inner cavity of the storage tank 1, and a glue delivery tube 5 is fixedly connected to the output end of the peristaltic pump 4. The end of the glue delivery tube 5 away from the peristaltic pump 4 passes through the side wall of the storage tank 1 and is fixedly connected to the side wall of the storage tank 1. When the peristaltic pump 4 is started, the adhesive inside the storage tank 1 can be introduced into the glue delivery tube 5 through the peristaltic pump 4, and transferred along the glue delivery tube 5 to the filling tube 9 for filling.

[0033] Reference Figure 1 and Figure 2 The flow diversion component includes a tee pipe 6 installed on one end of the rubber delivery pipe 5 away from the peristaltic pump 4, one of the discharge ports of the tee pipe 6 is connected to a transmission pipe 7 for delivering the adhesive to other production lines, and one end of the filling pipe 9 away from the filling head 10 is fixedly connected to the other discharge port of the tee pipe 6. The tee pipe 6 is provided to divert the adhesive discharged from the rubber delivery pipe 5, so that the adhesive can be transferred to other production lines through the transmission pipe 7 for use during the gap of glue filling, thereby improving work efficiency.

[0034] Reference Figure 2 An arc-shaped curved pipe 8 is provided between the transmission pipe 7 and the tee pipe 6. The transmission pipe 7 is fixedly connected to the tee pipe 6 through the curved pipe 8, and the height of the end of the transmission pipe 7 connected to the curved pipe 8 is higher than the height of the end of the curved pipe 8 connected to the tee pipe 6. When the solenoid valve 16 is in the open state, since the height of the transmission pipe 7 is higher than the top height of the filling pipe 9, the adhesive is discharged along the filling pipe 9 for filling under the action of gravity. When the packaging container is full and needs to be replaced, the solenoid valve 16 is in the closed state. At this time, the adhesive cannot enter the filling pipe 9. Under the subsequent pressure, the adhesive can enter the transmission pipe 7 through the curved pipe 8, and the adhesive is transported to other production lines for use during the filling interval through the transmission pipe 7.

[0035] Reference Figure 3The top of the slide tube 12 is slidably connected with an adjusting rod 14, and a stopper bolt 15 is provided on the side wall of the connecting end of the slide tube 12 and the adjusting rod 14 and is screwed with the slide tube 12. The adjusting rod 14 is slidably connected to the top of the slide tube 12 so that the user can adjust the total length of the entire metering assembly by sliding the adjusting rod 14, thereby adjusting the liquid level of the adhesive filled in the packaging container. After the adjustment is completed, the user can screw the stopper bolt 15 into the slide tube 12 to squeeze the adjusting rod 14 to increase the friction between the adjusting rod 14 and the inner wall of the slide tube 12, so that the slide tube 12 and the adjusting rod 14 are relatively fixed.

[0036] Reference Figure 3 The floating plate 13 is a disc-shaped structure, and the buoyancy of the floating plate 13 is greater than the total gravity of the slide tube 12, the adjustment rod 14 and the limit bolt 15. The floating plate 13 can float on the adhesive liquid surface under its own buoyancy to achieve automatic measurement of the adhesive.

[0037] The implementation principle of the present application is as follows: when in use, the user first places the packaging container under the filling head 10. At this time, the slide tube 12 slides down under the action of gravity, pushing the float plate 13 to extend into the packaging container, so that the top of the slide tube 12 is away from the contact switch 17, and the solenoid valve 16 is in the open state. The user can then turn on the peristaltic pump 4 and inject the adhesive into the packaging container through the rubber delivery hose 5, the three-way pipe 6 and the filling pipe 9. Since the float plate 13 has a small density, it can float on the surface of the adhesive. As the liquid level of the adhesive injected into the packaging container increases, the float plate 13 is simultaneously moved under the action of buoyancy. The sliding tube 12 is gradually raised and pushed to move vertically upward until the top of the sliding tube 12 contacts the contact switch 17 so that the contact switch 17 starts to close the electromagnetic valve 16, and the filling head 10 stops pouring adhesive into the packaging container. Since the length of the sliding tube 12 is fixed, the height of the adhesive liquid level poured into the packaging container is the same, thereby realizing quantitative filling of the adhesive, and avoiding the current situation where most of the adhesive filling is manually controlled, extracted by a glue pump, and measured by workers visually, which is not only inefficient, but also prone to problems such as inaccurate measurement and glue overflow due to operating errors.
