Description

Technical Field

[0001] This utility model belongs to the field of sleeve technology, specifically relating to a sleeve used in the water chamber of a granulator. Background Technology

[0002] In the dry devolatilization process, in order to form a continuous and stable fluid after the adhesive passes through the mold, a certain feed rate needs to be ensured. Therefore, the adhesive does not flow through the mold before the predetermined feed rate is reached. The adhesive is discharged through a bypass valve via a side stream, and the discharge direction of the adhesive is different from the flow direction of the adhesive during the production process. When the feed rate reaches the required level, the switching valve allows the adhesive to flow into the mold and then into the water chamber for pelletizing.

[0003] In practice, after the adhesive is discharged through the bypass valve via a side line, a small amount of adhesive will still flow into the mold. When the adhesive remains in the mold hole of the mold, it will cause a blockage problem. When the bypass valve is closed and normal production resumes, the pressure in the mold hole will increase due to the blockage of adhesive in the mold hole, which will affect production and, in severe cases, cause a shutdown. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sleeve for use in the water chamber of a granulator.

[0005] To achieve the above objectives, this utility model discloses a sleeve for a water chamber in a granulator, comprising a cylinder body, a connecting bracket, and a locking assembly. The cylinder body is installed inside the water chamber of the granulator, with its two ends being a feed end and a discharge end, respectively. The end face of the feed end is used to abut against the discharge end face of the granulator's template. The projection of the outer side wall of the cylinder body is completely located within the projection of the inner side wall of the granulator's water chamber, and the projection of the inner side wall of the cylinder body can completely cover all the die holes of the granulator's template. The connecting bracket is installed at the discharge end, and the locking assembly is installed on the connecting bracket. The locking assembly includes a connector, which is used for detachable connection with the granulator's water chamber.

[0006] Preferably, the locking assembly further includes a rotating base, and one end of the connector is connected to the rotating base;

[0007] The rotating seat is rotatably connected to the connecting bracket, thereby enabling the connecting parts to move away from and towards the feed end.

[0008] Preferably, the rotating base is provided with a connecting block, and the connecting block is provided with a through hole;

[0009] The locking assembly also includes a nut;

[0010] One end of the connector is a screw, which slides through the through hole and is connected to the connecting block and fixed by the nut. The other end of the connector is used to connect to the water chamber of the granulator.

[0011] Preferably, the other end of the connector is a hook, which is fastened to the outer wall of the water chamber of the granulator.

[0012] Preferably, the connector includes a connecting rod and a retaining ring. The connecting rod is a screw rod, one end of which is connected to a nut, and the other end of which is rotatably connected to the retaining ring. The retaining ring is provided with the hook.

[0013] Preferably, there are two locking components, which are located on both sides of the cylinder.

[0014] Preferably, the connecting bracket includes a frame, a first connecting member and a second connecting member disposed on the frame, the first connecting member and the second connecting member being symmetrically arranged about the central axis of the cylinder, and two locking components being respectively installed on the first connecting part and the second connecting part.

[0015] Preferably, the frame is installed at the discharge end, and the free ends of both the first connector and the second connector extend to the feed end.

[0016] Preferably, the length of the cylinder is greater than the length of the water chamber of the granulator.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In this invention, the sleeve inside the water chamber of the granulator is moved into the water chamber when the adhesive liquid has not reached the predetermined feed amount, and the end face of the feed end abuts against the discharge end face of the granulator's template. At this time, the discharge port of the template is connected to the cylinder, but not to the material conveying pipe inside the water chamber. When the adhesive liquid flows out from the template die hole, it flows to the cylinder and then is discharged to the ground. When the adhesive liquid feed amount reaches the standard, the cylinder is removed from the water chamber, and the cutting device is moved into the water chamber for cutting and granulation.

[0019] Regardless of whether the glue feed amount is below standard or above standard, the glue flows towards the template, through the template mold hole, and into the cylinder (water chamber). Throughout the process, the glue in the template mold hole is continuously flowing, so there will be no glue blockage problem in the mold hole. This solves the glue blockage problem caused by a small portion remaining in the template mold hole due to glue discharge through the side line in the existing solution.

[0020] The feed end face of the cylinder abuts against the discharge end face of the granulator template. This avoids gaps between the two, which would allow substandard adhesive to be discharged through the gap and flow into the material conveying pipe in the water chamber, ultimately leading to uncontrollable product quality and reduced product quality.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] First, to explain the technology of this utility model in more detail, Figure 1 The corresponding pelletizer structure of the sleeve of this utility model is shown, which includes a feeding device 110, a template 120, a water chamber 130 and a cutting device.

[0030] A sleeve for use in the water chamber of a granulator, see [link / reference] Figures 2-3 The system includes a cylinder 200, a connecting bracket 300, and a locking assembly 400. The cylinder 200 is installed in the water chamber of the granulator. The two ends of the cylinder 200 are a feed end 210 and a discharge end 220, respectively. The end face of the feed end 210 abuts against the discharge end 220 of the granulator's die. This prevents gaps between the two, which could allow substandard adhesive to drain through these gaps and flow into the material conveying pipe 140 within the water chamber, ultimately leading to uncontrolled product quality and reduced product quality. The projection of the outer wall of the cylinder 200 is completely within the projection of the inner wall of the granulator's water chamber. This allows the cylinder 200 to be installed within the water chamber. The projection of the inner wall of the cylinder 200 completely covers all the die holes of the granulator's die, ensuring that after the cylinder 200 is installed, the adhesive discharged from the die holes can be completely discharged into the cylinder 200. The connecting bracket 300 is installed at the discharge end 220, which prevents interference between the connecting bracket 300 and the water chamber. The locking assembly 400 is installed on the connecting bracket 300 and includes a connector 410 for detachable connection with the water chamber of the granulator.

[0031] In this embodiment, when the adhesive liquid has not reached the predetermined feed amount, the sleeve body 200 is moved into the water chamber and the end face of the feed end 210 abuts against the discharge end 220 of the granulator template. At this time, the discharge port of the template is connected to the cylinder of the sleeve body 200, but not to the material conveying pipe in the water chamber. When the adhesive liquid flows out of the template die hole, it flows to the sleeve body 200 and then discharges from the sleeve body 200 to the ground. When the adhesive liquid feed amount reaches the standard, the sleeve body 200 is removed from the water chamber, and the cutting device is moved into the water chamber for cutting and granulation. Regardless of whether the adhesive liquid feed amount is not reached or reaches the standard, the flow direction of the adhesive liquid is towards the template, through the template die hole, and into the sleeve body 200 (water chamber). Throughout the process, the adhesive liquid in the template die hole is continuously flowing, so there will be no adhesive blockage problem in the die hole. This solves the adhesive blockage problem caused by a small portion remaining in the template die hole when the adhesive is discharged through the side line in the existing solution.

[0032] In this embodiment, the length of the cylinder 200 is greater than the length of the water chamber of the granulator. This allows substandard adhesive to be completely discharged from the water chamber, avoiding the problem of product quality being difficult to control due to some residue remaining in the water chamber.

[0033] In this embodiment, the locking assembly 400 further includes a rotating seat 440, and one end of the connector 410 is connected to the rotating seat 440. The rotating seat 440 is rotatably connected to the connecting bracket 300, thereby enabling the connector 410 to move away from and towards the feed end 210. By setting the rotating seat 440, when the cylinder 200 is installed on the water chamber, the rotating seat 440 can be turned towards the feed end 210, which facilitates the connection of the connector 410 to the water chamber; after the connector 410 is connected to the water chamber, the rotating seat 440 is turned away from the feed end 210, thereby locking the cylinder 200 inside the water chamber.

[0034] Specifically, the rotating shaft of the rotating seat 440 is parallel to the longitudinal diameter of the cylinder 200. When it rotates, it rotates towards the feed end 210 or the discharge end 220 of the cylinder 200, thereby driving the connecting piece 410 towards the feed end 210 or the discharge end 220 of the cylinder 200.

[0035] The rotating base 440 is U-shaped, which makes it easy for staff to operate by hand.

[0036] In this embodiment, the rotating base 440 is provided with a connecting block 441, and the connecting block 441 has a through hole. The locking assembly 400 also includes a nut 450; one end of the connecting member 410 is a screw, which passes through the through hole and is slidably connected to the connecting block 441 and fixed by the nut 450, and the other end of the connecting member 410 is used to connect to the water chamber of the granulator. The above-described specific structure of the locking assembly 400, by controlling the position of the nut 450 on the screw, adjusts the length of the connecting member 410 and the tightness of the connection, resulting in higher operability and better adaptability.

[0037] In this embodiment, the free end of the connector 410 is a hook, which is fastened to the outer wall of the water chamber of the granulator. The cylinder 200 is installed and fixed by fastening, which is simple in structure and easy to assemble.

[0038] The hook can be fastened to the structure on the outer side wall of the water tank, such as a flange structure, or a corresponding fastening structure can be installed on the outer side wall of the water tank.

[0039] In this embodiment, the connector 410 specifically includes a connecting rod 420 and a retaining ring 430. The connecting rod 420 is a screw, one end of which is connected to a nut 450, and the other end of which is rotatably connected to the retaining ring 430, which is the aforementioned hook. The connector 410 is specifically configured with a structure of connecting rod 420 and retaining ring 430. While ensuring connection to the water chamber, the retaining ring 430 allows the connecting rod 420 to slide against the connecting block 441 of the rotating seat 440, thereby controlling the actual length of the connector 410. The rotatable connection between the connecting rod 420 and the retaining ring 430 makes the overall structure more flexible and the connection more convenient.

[0040] In this embodiment, there are two locking components 400, located on opposite sides of the cylinder 200. Specifically, the connecting bracket 300 includes a frame 310, a first connecting member 410320 and a second connecting member 410330 mounted on the frame 310. The first connecting member 410320 and the second connecting member 410330 are symmetrically arranged about the central axis of the cylinder 200, and the two locking components 400 are respectively installed on the first connecting portion and the second connecting portion. The provision of two sets of locking components 400 improves the assembly reliability of the cylinder 200.

[0041] The frame 310 is installed at the discharge end 220, and the free ends of the first connector 410320 and the second connector 410330 both extend to the feed end 210.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
