Description

Technical Field

[0001] This utility model relates to the field of plastic hose sealing technology, specifically to a sealing device for irregularly shaped ends of plastic hoses. Background Technology

[0002] Plastic tube sealing is a key process in the packaging industry. Its core objective is to ensure the airtightness, safety, and aesthetics of the contents. Plastic tube sealing machines are industrial devices that seal tube openings using high-pressure fusion technology, and are widely used in the packaging processes of cosmetics, pharmaceuticals, and food industries. These machines are mainly divided into fully automatic, semi-automatic, and ultrasonic types, with ultrasonic technology being the mainstream choice due to its strong sealing effect.

[0003] Chinese patent CN2196505062U discloses a plastic hose irregular tail sealing device. When the hot melt plate needs to be replaced, the operator can control the movement of the limiting rod. The limiting rod can be separated from the limiting groove on the insert block, so that the operator can quickly remove the hot melt plate for replacement.

[0004] In the above solution, although the combination of limiting rods, limiting grooves and other structures makes the disassembly and replacement of the hot melt plate more convenient, the tail of the plastic hose is irregularly shaped and sealed by a welding head with a specific irregular shape. Replacing the hot melt structure as a whole would be costly. Moreover, the tail of the plastic hose after sealing is prone to sticking to the hot melt structure, which would hinder the next sealing operation.

[0005] Therefore, this utility model provides a sealing device for irregularly shaped ends of plastic hoses to solve the above problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the prior art, this utility model provides a plastic hose irregular tail sealing device to solve the problem that since the irregular tail sealing of plastic hoses relies on the welding head with a specific irregular shape, the method of replacing the entire hot melt structure will result in high cost, and the tail of the plastic hose after sealing is easy to adhere to the hot melt structure, which will hinder the next sealing operation.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A sealing device for the irregular tail of a plastic hose includes a fixing plate and two sealing blocks. The fixing plate is provided with a control component for the opposing movement of the two sealing blocks. Each of the two sealing blocks has a first mounting groove, and a fixing component can be detachably installed in each of the two first mounting grooves. A second mounting groove is provided on the fixing component, and a welding head component can be detachably installed in the second mounting groove. An energy converter is embedded in the fixing component, and the working end of the energy converter abuts against the welding head component. A second locking bolt is provided in the fixing component, and an air jet pipe is also provided on the fixing component, and the air jet pipe is connected to the second locking bolt.

[0009] Preferably, a connecting seat is fixedly connected to the fixing plate, and the bottom end of the connecting seat is mounted on the workbench.

[0010] Preferably, the control component includes a guide groove formed on a fixed plate, two guide blocks are slidably connected in the guide groove, and the cross-section of the guide blocks is cross-shaped, with the bottom end of the guide blocks fixedly connected to the end block.

[0011] Preferably, the control component further includes a fixed frame fixedly connected to the fixed plate, a cylinder is mounted on the fixed frame, a lifting seat is fixedly connected to the telescopic end of the cylinder, and hinge rods are hinged to both sides of the lifting seat, with the end of the hinge rod away from the lifting seat hinged to the guide block.

[0012] Preferably, it also includes a turntable, on which fixed fixtures arranged in a circular array are fixedly connected.

[0013] Preferably, a positioning block is fixedly connected to the first mounting groove, the fixing member has a positioning hole, and the fixing member is inserted into the positioning block through the positioning hole. A first locking bolt is threadedly connected to one side of the fixing member, and one end of the first locking bolt is threadedly connected to the positioning block.

[0014] Preferably, the fixing member has two second locking bolts threadedly connected to it, and one end of each second locking bolt is threadedly connected to the welding head.

[0015] Preferably, the fixing member is equipped with a connector, and the connector is connected to the gas storage pipe, and the connector is connected to the gas source through a hose.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. The second locking bolt is fixed in the second mounting groove of the fastener. The fastener is precisely positioned and securely connected by the positioning block, positioning hole, first locking bolt and end cap block. When it is necessary to change the irregular shape of the hose end, there is no need to replace the entire fastener and related structures including the energy converter. Only the welding head needs to be replaced by removing the second locking bolt. This not only greatly reduces the equipment maintenance cost of changing the irregular end cap style, but also simplifies the replacement operation process.

[0018] 2. High-pressure gas is introduced through the connector, and then blown directly onto the end of the sealed hose through the jet pipe connected to the gas storage pipe. The high-pressure gas can actively blow away any residue that may be attached to the welding head or fixing parts, thus avoiding adhesion problems at the source and ensuring the continuity of the sealing operation. This not only improves the overall production efficiency, but also avoids the deformation and appearance damage of the hose end caused by adhesion, further meeting the packaging industry's requirements for product aesthetics.

[0024] The following will refer to the attached reference. Figures 1 to 4 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0025] A device for sealing the irregular tail of a plastic hose includes a fixing plate 1 and two sealing blocks 3. A connecting seat 2 is fixedly connected to the fixing plate 1, and the bottom end of the connecting seat 2 is mounted on a workbench.

[0026] In this embodiment, the fixing plate 1 and the connecting seat 2 are connected to form an integral structure by welding, and the connecting seat 2 is fixed to the fixing seat by bolts or welding.

[0027] The fixed plate 1 is provided with a control component for moving the two sealing blocks 3 toward each other. The control component includes a guide groove 19 opened on the fixed plate 1. Two guide blocks 20 are slidably connected in the guide groove 19. The cross-section of the guide block 20 is cross-shaped. The bottom end of the guide block 20 is fixedly connected to the sealing block 3.

[0028] The guide block 20 can move laterally on the guide groove 19, and the cooperation between the guide block 20 and the guide groove 19 will prevent the guide block 20 from moving longitudinally.

[0029] In this embodiment, the control component also includes a fixed frame 16 fixedly connected to the fixed plate 1. A cylinder 17 is installed on the fixed frame 16. A lifting seat 18 is fixedly connected to the telescopic end of the cylinder 17. A hinge rod 21 is hinged to both sides of the lifting seat 18, and the end of the hinge rod 21 away from the lifting seat 18 is hinged to the guide block 20.

[0030] When it is necessary to bring the two sealing blocks 3 closer together, the lifting seat 18 is driven to move upward by the telescopic end of the cylinder 17, and under the action of the hinge rod 21, the two guide blocks 20 can move towards each other in the guide groove 19, thereby causing the guide blocks 20 to drive the sealing blocks 3 to move synchronously.

[0031] In this embodiment, a turntable 22 is also included, on which a fixed fixture 23 arranged in a circular array is fixedly connected.

[0032] The turntable 22 is mounted on the drive structure. By placing the plastic hose inside the fixed fixture 23 and rotating the turntable 22, the fixed fixture 23 rotates and transports the plastic hose to the sealing part for sealing.

[0033] Both sealing blocks 3 are provided with first mounting grooves 4, and fixing parts 5 can be detachably installed in both first mounting grooves 4. Fixing parts 5 are provided with second mounting grooves 6, and welding head parts 7 can be detachably installed in the second mounting grooves 6. An energy converter 8 is embedded in the fixing parts 5, and the working end of the energy converter 8 abuts against the welding head parts 7. A second locking bolt 12 is provided in the fixing parts 5, and an air jet pipe 14 is also provided on the fixing parts 5, and the air jet pipe 14 is connected to the second locking bolt 12.

[0034] The energy converter 8 is connected to an external ultrasonic generator and is made of ceramic. The energy converter 8 converts high-frequency electrical energy into small mechanical vibrations of the same frequency, which are transmitted to the welding head 7 through the amplitude transformer on the energy converter 8. This causes the welding head 7 to generate high temperature, and the sealing of the plastic hose is completed by the closing of the two welding heads 7.

[0035] A positioning block 9 is fixedly connected to the first mounting slot 4. A positioning hole 10 is provided on the fixing member 5, and the fixing member 5 is inserted into the positioning block 9 through the positioning hole 10. A first locking bolt 11 is threadedly connected to one side of the fixing member 5, and one end of the first locking bolt 11 is threadedly connected to the positioning block 9.

[0036] When installing the fastener 5, the fastener 5 needs to be inserted into the positioning block 9 through the positioning hole 10, and the fastener 5 is placed in the first mounting groove 4. After the fastener 5 is installed on the fastener 5 through the first locking bolt 11, one end of the first locking bolt 11 is screwed onto the positioning block 9 to complete the fixing of the fastener 5.

[0037] The welding head 7 and the fixing part 5 are separate. The fixing part 5 has two second locking bolts 12 threadedly connected. One end of the second locking bolt 12 is threadedly connected to the welding head 7. The welding head 7 is fixed to the fixing part 5 by the second locking bolt 12. When it is necessary to change the irregular shape of the sealing end, the welding head 7 can be disassembled and replaced.

[0038] The fastener 5 is equipped with a connector 15, which is connected to the gas storage pipe 13 and connected to the gas source through a hose.

[0039] High-pressure gas is delivered to the gas storage pipe 13 through the hose and connector 15, and then sprayed out through the jet pipe 14 to blow air onto the sealed end of the hose to prevent the end of the hose from sticking to the welding head 7 and the fixing part 5.
