Description

Technical Field

[0001] The utility model belongs to the technical field of particle manufacturing molds, and particularly relates to a particle extrusion mold replacement device. Background Art

[0002] Improving soil mineral content requires biomass fertilizers. Prepared raw materials are typically granulated and dried for longer-term storage. Traditional granulation equipment includes screw extruders, cylindrical pelletizers, wet powder granulators, and powder granulators. Perforated die granulators are particularly suitable for extruding coarse materials, especially since the die can be replaced to adjust the extrusion aperture to a variety of diameters.

[0003] Problems with existing technologies:

[0004] In the middle of the hydraulic granulator, a space is reserved for replacing the perforated molds. The perforated molds are sent into the replacement space one by one using a one-to-four motor method. In order to ensure the smooth entry and exit of the perforated molds, a gap is often left between the replacement space and the perforated molds. It is inconvenient to close the gap, so the material leaks along the gap when being squeezed, reducing the tightness of the perforated molds after replacement. Utility Model Content

[0005] The purpose of the utility model is to provide an extrusion particle mold replacement device, which can seal the gap after the mold is replaced, prevent the material from leaking from the gap when being extruded, and conveniently improve the tightness after the mold is replaced.

[0006] The technical solutions adopted by this utility model are as follows:

[0007] A device for replacing an extrusion particle mold includes a pressing cylinder and a perforated mold. A square groove that is inserted into the perforated mold is formed on one side of the pressing cylinder. A transverse movement module facing the square groove is horizontally arranged on the outside of the pressing cylinder. A support fork is installed at the output end of the transverse movement module. The transverse movement module and the support fork push the perforated mold into the square groove. Metal baffles are fixed on both sides of the square groove. A sealing strip is bonded to the side of the metal baffle close to the perforated mold. The perforated mold is placed flatly inside the support fork, and then the transverse movement module pushes the support fork toward the pressing cylinder to send the perforated mold into the square groove and place it horizontally inside the pressing cylinder. At the same time, the edge of the perforated mold is tightly inserted between these sealing strips. The gap between the perforated mold and the square groove is sealed by the sealing strip and the metal baffle to prevent the material from leaking from the gap when being extruded, thereby facilitating the improvement of the tightness after the mold is replaced. When it is necessary to replace the hole mold with a different mesh number later, the transverse movement module can be controlled to pull the support fork away from the pressing cylinder body, and the hole mold in the square groove can be taken out so that the hole mold in the support fork can be taken out.

[0008] As a preferred solution, the support fork includes a support handle and a concave fork body fixedly connected to one end of the support handle, the opening of the concave fork body clamps both sides of the mold with a hole, a limiting rod is fixed to the inner wall of the concave fork body, one end of the limiting rod is inserted into the outside of the mold with a hole, and the support handle is used to connect the slide of the transverse module so that the concave fork body is suspended in the air and carries the mold with a hole, and then the limiting rod is used to tighten the mold with a hole to form a limiting effect, so that the mold with a hole is centered and aligned with the square groove, and the concave fork body can avoid the metal baffle during movement to avoid mutual interference.

[0009] As a preferred solution, the sealing strip is bonded with an alloy guide plate at one end close to the transverse module. The alloy guide plate has an arc, and the arc surface is used to guide the perforated mold to move toward the middle of the square groove, playing a guiding role to prevent deviation. It is more wear-resistant than the sealing strip, and the wear alloy guide plate is preferred.

[0010] As a preferred solution, a buffer damping pad is bonded to the side of the square groove away from the transverse movement module. The buffer damping pad is horizontally facing the perforated mold. After the perforated mold is immersed in the square groove, it presses against the buffer damping pad. The deformation of the buffer damping pad leaves an installation margin to avoid hard collision.

[0011] As a preferred solution, guide rods parallel to the transverse module are fixed on both sides of the concave fork body, and a distance is left between the two guide rods and the support handle.

[0012] As a preferred solution, an oil storage groove is provided on the upper surface of the perforated mold, and the width of the oil storage groove is smaller than the width of the square groove.

[0013] As a preferred solution, a reinforcing rib is welded on one side of the metal baffle away from the sealing strip, and one end of the reinforcing rib is welded to the outside of the pressing cylinder.

[0014] The technical effects achieved by this utility model are:

[0015] The utility model places the perforated die flat inside the support fork, and then uses the transverse movement module to push the support fork toward the pressing cylinder, placing the perforated die into the square slot and placing it horizontally inside the pressing cylinder. At the same time, the edge of the perforated die is tightly inserted between these sealing strips, and the gap between the perforated die and the square slot is sealed by the sealing strips and metal baffles to prevent material from leaking through the gap when squeezed, thereby facilitating the improvement of the tightness of the die after replacement. If it is necessary to subsequently replace a perforated die with a different mesh size, the transverse movement module can be controlled to pull the support fork away from the pressing cylinder, remove the perforated die from the square slot, and then remove the perforated die from the support fork.

[0016] The utility model utilizes a supporting handle to connect the slide of the transverse movement module, so that the concave fork body is suspended in the air and carries the mold with a hole, and then the mold with a hole is tightly inserted into the mold with a limiting rod to form a limiting effect, so that the mold with a hole is centered and aligned with the square groove, and the concave fork body can avoid the metal baffle during the movement to avoid mutual interference.

[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0025] like Figure 1-Figure 5 As shown, a device for replacing an extrusion particle mold includes a pressing cylinder body 1 and a perforated mold 2. The pressing cylinder body 1 is erected on a workbench and fixed by bolts. A square groove 3 is provided on one side of the pressing cylinder body 1 for inserting into the perforated mold 2. A transverse module 5 facing the square groove 3 is horizontally arranged on the outside of the pressing cylinder body 1. A supporting fork 4 is installed at the output end of the transverse module 5. The transverse module 5 and the supporting fork 4 push the perforated mold 2 into the square groove 3. Metal baffles 7 are welded on both sides of the square groove 3, and a sealing strip 6 is bonded to the side of the metal baffle 7 close to the perforated mold 2.

[0026] Furthermore, the square groove 3 is arranged between the feed hopper and the discharge hopper of the pressing cylinder 1. After being inserted into the perforated die 2, it can receive the material, and then drive the pressing plate to press the material through the hydraulic system to extrude particles from the circular hole of the perforated die 2.

[0027] Furthermore, the spacing between the openings of the support forks 4 is wider than the distance between the metal baffles 7 , so that after the perforated mold 2 is inserted into the square groove 3 , the support forks 4 are arranged outside the metal baffles 7 .

[0028] Through the above structure, its working principle is: before extruding the particles, select a perforated die 2 with a specified mesh size of holes, place it flat inside the support fork 4, and then control it through an industrial computer, transmit the signal to the transverse movement module 5 through the relay, push the support fork 4 to move toward the pressing cylinder 1, and send the perforated die 2 into the square groove 3, and place it horizontally inside the pressing cylinder 1.

[0029] At the same time, the edge of the perforated mold 2 is inserted tightly between these sealing strips 6, and the gap between the perforated mold 2 and the square groove 3 is sealed by the sealing strip 6 and the metal baffle 7 to prevent the material from leaking from the gap when being squeezed, thereby facilitating the improvement of the tightness after the mold is replaced.

[0030] In this way, after the loose material is fed from the feed hopper into the pressing cylinder 1, the hydraulic system is activated to drive the pressing plate to press the material downward, extruding the particles along the perforated die 2, and the particles slide out of the discharge hopper. Later, when it is necessary to replace the perforated die 2 with a different mesh size, the transverse module 5 can be controlled to pull the support fork 4 away from the pressing cylinder 1, remove the perforated die 2 from the square slot 3, and then remove the perforated die 2 from the support fork 4.

[0031] During this process, the surface of the sealing strip 6 can be coated with a smooth coating to reduce the friction between the sealing strip 6 and the perforated mold 2, making the insertion and removal of the perforated mold 2 in the square groove 3 smoother.

[0032] Refer to the attached Figure 1 and Figure 3 The supporting fork 4 includes a supporting handle 401 and a concave fork body 402 fixedly connected to one end of the supporting handle 401. The opening of the concave fork body 402 clamps the two sides of the perforated mold 2. A limiting rod 403 is fixed to the inner wall of the concave fork body 402. One end of the limiting rod 403 is inserted into the outside of the perforated mold 2. The supporting handle 401 is used to connect the slide of the transverse module 5 so that the concave fork body 402 is suspended in the air and carries the perforated mold 2. The limiting rod 403 is then used to tighten the perforated mold 2 to form a limiting effect, so that the perforated mold 2 is centered and aligned with the square groove 3, and the concave fork body 402 can avoid the metal baffle 7 during movement to avoid mutual interference.

[0033] Refer to the attached Figure 4 and Figure 5The sealing strip 6 is bonded with an alloy guide plate 8 at one end close to the transverse module 5. The alloy guide plate 8 has an arc, and the arc surface is used to guide the hole mold 2 to move toward the middle of the square groove 3, playing a guiding role to prevent deviation. It is more wear-resistant than the sealing strip 6, and the wear-resistant alloy guide plate 8 is preferred.

[0034] Refer to the attached Figure 1 and Figure 4 A buffer damping pad 9 is bonded to the side of the square groove 3 away from the transverse module 5. The buffer damping pad 9 is horizontally facing the perforated mold 2. After the perforated mold 2 is immersed in the square groove 3, it is pressed against the buffer damping pad 9. The deformation of the buffer damping pad 9 leaves an installation margin to avoid hard collision.

[0035] Refer to the attached Figure 1 and Figure 3 Guide rods 10 parallel to the transverse module 5 are fixed on both sides of the concave fork body 402. One end of the guide rod 10 is fixedly connected to one side of the concave fork body 402 by a screw, and the other end is inserted into the outside of the transverse module 5 through a steel pipe. There is a distance between the two guide rods 10 and the support handle 401. When the concave fork body 402 moves horizontally, it drives the guide rod 10 to slide, forming a guiding effect.

[0036] Refer to the attached Figure 1 and Figure 2 An oil storage tank 11 is provided on the upper surface of the hole mold 2. The width of the oil storage tank 11 is smaller than the width of the square groove 3. Lubricating oil is added to the oil storage tank 11 to alleviate the friction between the upper surface of the hole mold 2 and the inner wall of the square groove 3 and reduce the obstruction.

[0037] Refer to the attached Figure 1 、 Figure 4 and Figure 5 The metal baffle 7 is welded with a reinforcing rib 12 on the side away from the sealing strip 6, and one end of the reinforcing rib 12 is welded to the outside of the pressing cylinder 1. In this embodiment, thirteen reinforcing ribs 12 are welded on each metal baffle 7 to support the metal baffle 7 from different positions so that it can firmly support the sealing strip 6.

[0038] The working principle of the utility model is as follows: when working, the hole mold 2 is placed flatly inside the supporting fork 4, and then the lateral movement module 5 pushes the supporting fork 4 to move toward the pressing cylinder 1, and the hole mold 2 is sent into the square groove 3 and placed horizontally inside the pressing cylinder 1.

[0039] At the same time, the edge of the perforated mold 2 is inserted tightly between these sealing strips 6, and the gap between the perforated mold 2 and the square groove 3 is sealed by the sealing strip 6 and the metal baffle 7 to prevent the material from leaking from the gap when being squeezed, thereby facilitating the improvement of the tightness after the mold is replaced.

[0040] When it is necessary to replace the perforated mold 2 with a different mesh number of holes later, the transverse movement module 5 can be controlled to pull the support fork 4 away from the pressing cylinder 1 and take out the perforated mold 2 in the square groove 3 so that the perforated mold 2 in the support fork 4 can be taken out.

[0041] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
