Description

Technical Field

[0001] This utility model relates to the field of PUR hot melt adhesive extraction assistance, and in particular to an extraction assistance device for PUR hot melt adhesive equipment. Background Technology

[0002] PUR hot melt adhesive is a high-performance adhesive often used in bonding applications requiring high strength and durability. Drum-packaged adhesive is commonly used in production, but because of its large volume, it is not easy to move around, so it is usually poured into a small container for use.

[0003] For example, the glue extraction auxiliary device for a PUR hot melt glue machine disclosed in Chinese Patent No. CN212681570U allows the extraction tube to move upwards out of the hot melt glue bucket after it has finished extracting the glue. This allows the extraction tube to extract glue from hot melt glue buckets of different heights. However, the above solution only uses a limiting frame and a movable plate to simply fix the glue bucket, which cannot adapt to glue buckets of different sizes. Therefore, it cannot stably fix the position of the glue bucket. Since the glue in the bucket is liquid, if the glue bucket is not fixed, it may tilt during the glue extraction process, causing glue leakage and overflow, which poses a certain danger to production personnel and makes the equipment a significant safety hazard. Utility Model Content

[0004] The main purpose of this utility model is to provide a glue extraction auxiliary device for PUR hot melt adhesive equipment, which can effectively solve the technical problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A glue extraction auxiliary device for PUR hot melt adhesive equipment includes a base, a glue tank placed on top of the base, and fixed clamps on both sides of the glue tank. The two sets of fixed clamps are symmetrically distributed about the central axis of the base. The base has two sets of movable grooves, which are symmetrically distributed. Movable blocks are slidably disposed in the movable grooves, and threaded grooves are formed on the movable blocks. A screw is rotatably connected to one side of each movable groove, and the screw is threadedly connected to the threaded groove. A connecting assembly is provided on the fixed clamps to engage the fixed clamps and the movable blocks together. A transmission assembly is provided on the base to synchronously drive the two sets of screws to rotate.

[0007] As a further embodiment of this utility model, the connecting assembly includes a connecting groove formed on the fixed clamping plate, the movable block is welded with a connecting block, one end of the connecting block extends into the connecting groove, a circular through hole is formed on one side of the connecting groove, a spring is connected in the circular through hole, a fixing rod is connected to the other end of the spring, a fixing groove is formed on one side of the connecting block, and one end of the fixing rod extends into the fixing groove.

[0008] As a further embodiment of this utility model, a movable groove is provided on one side of the circular through hole, and a handle is movably disposed in the movable groove, with one end of the handle being fixedly connected to one side of the fixed rod.

[0009] As a further embodiment of this utility model, the transmission assembly includes sprockets mounted on two sets of screws, with chains connected to the sprockets. A motor is fixedly connected to one side of the base, and the motor output end extends through the movable groove and is connected to a set of screws.

[0010] As a further embodiment of this utility model, one side of each of the two sets of fixing plates is connected to an anti-slip pad, and one side of the anti-slip pad is in contact with the outer wall of the rubber bucket.

[0011] As a further embodiment of this utility model, a protective shell is snapped onto one side of the base.

[0012] As a further embodiment of this utility model, a bracket is provided on the top of the base, and a glue-pulling device is provided on the bracket.

[0013] The beneficial effects of this utility model are as follows:

[0014] After the glue bucket is placed on the base, the transmission component drives two sets of screws to rotate synchronously. The two sets of screws, in conjunction with the threaded grooves, drive the movable block to slide within the grooves. The movable block is connected to the fixed clamping plate through the connecting component, thereby moving the fixed clamping plate towards the glue bucket. The two sets of fixed clamping plates then press against the side wall of the glue bucket for clamping and fixing, thus fixing the position of the glue bucket. This makes it easier for the equipment to fix glue buckets of different sizes, preventing the glue inside the bucket from tilting during the glue extraction process, which could lead to glue leakage or overflow. This avoids potential dangers to production personnel and greatly reduces the safety hazards of the equipment.

[0015] Align the connecting block with the connecting slot on the fixed clamp and insert it. After the connecting block is inserted into the connecting slot, the spring in the circular through hole pushes the fixing rod into the fixing slot, fixing the connecting block in the connecting slot. This connects the fixed clamp and the movable block together, making it easy for the staff to change the appropriate fixed clamp according to the shape of the glue bucket. This also makes it easy for the fixed clamp to fit tightly with the glue bucket and to fix the position of the glue bucket. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1-5 As shown, a glue extraction auxiliary device for a PUR hot melt adhesive equipment includes a base 1, a glue tank 2 placed on top of the base 1, fixed clamps 3 on both sides of the glue tank 2, the two sets of fixed clamps 3 being symmetrically distributed about the central axis of the base 1, two sets of movable grooves 4 being provided on the base 1, the two sets of movable grooves 4 being symmetrically distributed, movable blocks 5 being slidably arranged in the movable grooves 4, the movable blocks 5 being provided with threaded grooves, and a screw 6 being rotatably connected to one side of the movable grooves 4, the screw 6 being threadedly connected to the threaded grooves.

[0024] Among them, one side of each of the two sets of fixing plates 3 is connected to an anti-slip pad 10, and one side of the anti-slip pad 10 is in contact with the outer wall of the glue bucket 2. The anti-slip pad 10 increases the friction with the glue bucket 2, which greatly increases the stability of the glue bucket 2.

[0025] In this embodiment, the fixed clamping plate 3 is provided with a connecting component, which is used to snap the fixed clamping plate 3 and the movable block 5 together. The base 1 is provided with a transmission component, which is used to synchronously drive the two sets of screws 6 to rotate.

[0026] When it is necessary to extract glue from the glue bucket 2, after placing the glue bucket 2 on the base 1, the transmission component drives the two sets of screws 6 to rotate synchronously. The two sets of screws 6, in conjunction with the threaded groove, drive the movable block 5 to slide in the movable groove 4. The movable block 5 is connected to the fixed clamping plate 3 through the connecting component, so that the movable block 5 drives the fixed clamping plate 3 to move towards the glue bucket 2, and the two sets of fixed clamping plates 3 are pressed against the side wall of the glue bucket 2 for clamping and fixing. This fixes the position of the glue bucket 2, making it easier for the equipment to fix glue buckets of different sizes, and preventing the glue in the glue bucket 2 from tilting during the glue extraction process, which could lead to glue leakage or overflow. This avoids certain dangers to production personnel and greatly reduces the safety hazards of the equipment.

[0027] In this embodiment, the connecting component includes a connecting groove 12 formed on the fixed clamping plate 3, a connecting block 13 welded to the movable block 5, one end of the connecting block 13 extending into the connecting groove 12, a circular through hole formed on one side of the connecting groove 12, a spring 15 connected in the circular through hole, a fixing rod 14 connected to the other end of the spring 15, a fixing groove 16 formed on one side of the connecting block 13, and one end of the fixing rod 14 extending into the fixing groove 16.

[0028] By aligning the connecting groove 12 on the fixed clamp 3 with the connecting block 13 and inserting it, when the connecting block 13 is inserted into the connecting groove 12, the spring 15 in the circular through hole pushes the fixing rod 14 into the fixing groove 16, fixing the connecting block 13 in the connecting groove 12, thereby connecting the fixed clamp 3 and the movable block 5 together. This makes it convenient for the staff to change the appropriate fixed clamp 3 according to the shape of the glue bucket 2, so that the fixed clamp 3 can fit tightly with the glue bucket 2 and the position of the glue bucket 2 can be fixed.

[0029] In this embodiment, a movable groove 17 is provided on one side of the circular through hole, and a handle 18 is movably disposed in the movable groove 17. One end of the handle 18 is fixedly connected to one side of the fixed rod 14.

[0030] The movable groove 17 facilitates the movement of the handle 18 to move the fixing rod 14, thereby pulling the fixing rod 14 out of the fixing groove 16, releasing the fixing of the connecting block 13, and making it convenient for staff to replace the clamp.

[0031] In this embodiment, the transmission component includes sprockets 8 mounted on two sets of screws 6, with chains 9 connected to the sprockets 8. A motor 7 is fixedly connected to one side of the base 1, with the output end of the motor 7 extending into the movable groove 4. The output end of the motor 7 is connected to a set of screws 6, and a protective shell 11 is snapped onto one side of the base 1.

[0032] The motor 7 drives a set of screws 6 to rotate, which in turn drives another set of screws 6 to rotate with the sprocket 8 and chain 9 at the other end, thus making the two sets of screws 6 rotate synchronously. The sprocket 8 and chain 9 are protected by the protective shell 11, which greatly increases the service life of the equipment.

[0033] In this embodiment, a bracket 19 is provided on the top of the base 1, and a glue-removing device 20 is provided on the bracket 19.

[0034] The glue extraction device 20 is connected to the base 1 by the bracket 19, which facilitates the glue extraction device 20 to extract glue from the glue tank 2.

[0035] It should be noted that this utility model is an auxiliary device for drawing glue from a PUR hot melt adhesive equipment. When it is necessary to draw glue from the glue bucket 2, the glue bucket 2 is placed on the base 1, and the motor 7 drives a set of screws 6 to rotate. In conjunction with the sprocket 8 and chain 9 at the other end, the other set of screws 6 is driven to rotate, so that the two sets of screws 6 rotate synchronously. The two sets of screws 6, together with the threaded groove, drive the movable block 5 to slide in the movable groove 4. The movable block 5 is connected to the fixed clamping plate 3 through the connecting component, so that the movable block 5 drives the fixed clamping plate 3 to move towards the glue bucket 2, and the two sets of fixed clamping plates 3 are pressed against the side wall of the glue bucket 2 for clamping and fixing, thus fixing the position of the glue bucket 2. This makes it easier for the equipment to fix glue buckets of different sizes, and avoids the glue in the glue bucket 2 from tilting during the glue drawing process, which would cause glue leakage and overflow.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
