An injection molding machine feeding device

Abstract

The present invention relates to the technical field of injection molding machines, and specifically relates to an inlet device for an injection molding machine, which includes an injection molding machine, a base, a spiral tube device, and a motor; an inlet assembly connected thereto is further provided on one side of the injection molding machine, and the inlet assembly includes a housing, a fixed support rod, a first transmission mechanism, a first linear driver, a toggle plate, and a transmission rod. Through a fixed bracket and a first transmission mechanism mounted on the fixed bracket, the toggle plate can be arranged inside the housing around the fixed support rod through a first connecting block, so that the first linear driver drives the toggle plate to move through the first transmission structure. Since the transmission rod is hinged to the toggle plate and the inner wall of the housing, the toggle plate makes a reciprocating arc movement while being partially fixed to prevent it from falling due to gravity. Therefore, since the toggle plate is in a V shape, it can strengthen the force on the material below through air pressure during the descending process, thereby further enhancing the anti-blocking effect.

Description

Technical Field

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention provides a feeding device for an injection molding machine, which protects the internal structure through a cover to prevent a large amount of impurities from entering the city, and then arranges a fixed support rod inside the cover and on the same axis as the circle where the cross section of the cover is located, and arranges a first cavity and a first slide groove so that a toggle plate connected to the first connecting block can be arranged inside the cover around the fixed support rod, so that the first linear drive drives the toggle plate to move up and down through the first transmission structure, and since the transmission rod is hinged to the toggle plate and the inner wall of the cover, the toggle plate can move in an orderly arc shape, and at the same time, the toggle plate is partially fixed to prevent it from falling due to gravity and reducing the transmission effect, so that since the toggle plate is in a V-shape, it can strengthen the force on the material below through air pressure during the descent process, thereby further enhancing the anti-blocking effect.

[0018] 2. The present invention provides a feeding device for an injection molding machine, which strengthens the strength of the V-shape by setting a first reinforcing rib to prevent it from breaking, and facilitates its processing by using a first recessed portion and a first raised portion while reducing its weight to prevent excessive gravity from affecting the up and down reciprocating motion of the toggle plate.

[0019] 3. The present invention provides a feeding device for an injection molding machine, which is hinged to a transmission rod through a first connecting port, and then the second connecting block between the vertical plates is clamped by the vertical plate. At the same time, a plurality of second sliding blocks corresponding to the second sliding grooves on the second connecting block facilitate the connection between the two so as to move in an orderly manner and provide support for the second connecting block to prevent it from falling due to gravity. The plurality of second sliding blocks are provided to prevent one end of the second connecting block from being too heavy and causing tilting, which affects the transmission effect.

[0020] 4. The present invention provides a feeding device for an injection molding machine, which facilitates the insertion of a snap-in plate and the snap connection between a nut and a thread by setting the second sliding block into a cylindrical shape and passing it through the outside of one end of a vertical plate. The end of the snap-in plate close to the vertical plate is made of a flexible graphite material, and the self-lubricating property provided by the flexible graphite material prevents it from preventing the second connecting block from sliding.

[0021] 5. The present invention provides a feeding device for an injection molding machine, which pushes a first connecting rod connected to it through a second slot through a first linear drive, so that the first connecting rod passes through the first slot to push the first transmission block to drive the first connecting block to connect, and the first elastic member is compressed by the thrust to facilitate the first linear drive to reset by elastic force when it stops pushing.

[0022] 6. The feeding device of the injection molding machine provided by the present invention enables the bolt to rotate different distances by adjusting the number of shims, thereby strengthening the force for pushing the second connecting rod, so that the push plate can push the second elastic member to change its elastic force. As a result, the value of preventing the first elastic member from changing for a long time through the compression of the second elastic member is increased, and its service life is extended. The limiting groove and the limiting block are used to prevent the second elastic member connected to the push plate from rotating together, thereby reducing the service life of the second elastic member.

[0023] 7. The feeding device of the injection molding machine provided by the present invention makes the length of the first transmission block greater than the length of the first chute, so that the material cannot enter the fixed support rod through the first chute by means of the first transmission block. Then, one end of the first connecting rod is fixed through the cap and the first through hole to prevent its inclination from affecting the transmission effect.

[0024] 8. The feeding device of the injection molding machine provided by the present invention is provided with two feeding ports at the top of the housing, and funnels with an arch-shaped bottom end are provided at the two feeding ports to facilitate the placement of the first linear actuator and prevent the first linear actuator from affecting the transmission.

[0048] To further understand the features, technical means, specific purposes, and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0049] As Figures 1 to 14 shown, the present application provides:

[0050] An injection molding machine feeding device includes an injection molding machine, a base, a spiral tube device, and a motor; an inlet assembly is further provided on one side of the injection molding machine and is connected to the injection molding machine. The inlet assembly includes a housing 1, a fixed support rod 2, a first transmission mechanism 3, a first linear driver 4, a dialing plate 5, and a transmission rod 6. The housing 1 is arranged above the spiral tube device and is connected to the spiral tube device. An inlet port 1a and an outlet port 1b are respectively arranged at the top and bottom of the housing 1; the fixed support rod 2 is arranged inside the housing 1 and is arranged on the same axis as the circle where the cross-section of the housing 1 is located. A first cavity 2a is arranged inside the fixed support rod 2, and a plurality of uniformly distributed first chutes 2b are further arranged on the outer surface of the fixed support rod 2. Each first chute 2b communicates with the first cavity 2a; the first transmission mechanism 3 is movably arranged inside the first cavity 2a, and a plurality of first connecting blocks 3a corresponding to the first chutes 2b are arranged on the first transmission mechanism 3; the first linear driver 4 is arranged inside the housing 1 and is connected to the first transmission mechanism 3. The number of the dialing plates 5 is the same as that of the first connecting blocks 3a and they are in one-to-one correspondence. One end of each dialing plate 5 is hinged to the corresponding first connecting block 3a and each dialing plate 5 is in an inverted V shape; the number of the transmission rods 6 is the same as that of the dialing plates 5 and they are in one-to-one correspondence. One end of the transmission rod 6 is slidably connected to the dialing plate 5, and the other end of the transmission rod 6 is hinged to the inner wall of the housing 1.

[0051] Based on the above embodiments, the technical problem that the present application wants to solve is how to enhance the anti-blocking effect during material transmission. For this reason, as Figures 1 to 14As shown in the figure, in this application, the housing 1 protects the internal structure to prevent a large amount of return impurities from entering. Then, the fixed support rod 2 is arranged inside the housing 1 and is set on the same axis as the circle where the cross-section of the housing 1 is located. The first cavity 2a and the first chute 2b are set so that the toggle plate 5 connected to the first connecting block 3a can be arranged inside the housing 1 around the fixed support rod 2. Thus, the first linear actuator 4 drives the toggle plate 5 to move up and down through the first transmission structure. Since the transmission rod 6 is hinged to the toggle plate 5 and the inner wall of the housing 1, the toggle plate 5 can move in an orderly arc shape while being partially fixed to prevent it from falling due to gravity and reducing the transmission effect. Therefore, because the toggle plate 5 is in a V shape, it can strengthen the force on the materials below through air pressure during the descending process, thereby further enhancing the anti-blocking effect. It should be noted that the injection molding machine, the base, the spiral pipe device, and the motor are prior arts, so they are not shown in the figure. At the same time, a plurality of annular placement grooves can be arranged inside the housing 1, and an annular placement block is arranged at one end of the plurality of transmission rods 6 connected to the inside of the housing 1, so as to strengthen the connection effect between the two and facilitate disassembly. At the same time, a plurality of first chutes 2b for upper and lower grading are set to realize the grading of the first connecting block 3a, and then drive the toggle plate 5 to be graded, thereby further increasing the anti-blocking effect.

[0052] Furthermore:

[0053] A triangular first protrusion 5a is arranged on the toggle plate 5. A plurality of uniformly distributed first depressions 5a1 are arranged on the first protrusion 5a, and the first depressions 5a1 and the first protrusion 5a form a plurality of uniformly distributed first reinforcing ribs 5a2.

[0054] Based on the above embodiments, the technical problem that this application wants to solve is how to strengthen the strength of the toggle plate 5. For this purpose, as shown in FIGS. 11 to 13, this application strengthens the strength of the V-shaped toggle plate 5 by setting the first reinforcing ribs 5a2 to prevent it from breaking, and at the same time, the first depressions 5a1 and the first protrusion 5a facilitate its processing and reduce its weight to prevent the excessive gravity from affecting the up and down reciprocating movement process of the toggle plate 5. Figure 12 - to 13, this application strengthens the strength of the V-shaped toggle plate 5 by setting the first reinforcing ribs 5a2 to prevent it from breaking, and at the same time, the first depressions 5a1 and the first protrusion 5a facilitate its processing and reduce its weight to prevent the excessive gravity from affecting the up and down reciprocating movement process of the toggle plate 5.

[0055] Furthermore:

[0056] Two vertical plates 5b extending downward are arranged on the toggle plate 5. A second chute 5b1 is arranged on each of the two vertical plates 5b, and a second connecting block 5b2 is also arranged between the two vertical plates 5b. A plurality of second sliders 5b3 corresponding to the second chute 5b1 are arranged on the second connecting block 5b2, and a first hinge opening 5b4 recessed inward is arranged at the bottom end of the second connecting block 5b2.

[0057] Based on the above embodiments, the technical problem that the present application aims to solve is how to strengthen the connection effect between the transmission plate and the toggle plate 5. Figure 4 and Figure 12 As shown, the present application is hinged with the transmission rod 6 through the first connecting port, and then the second connecting block 5b2 between the vertical plates is clamped by the vertical plate 5b, and at the same time, multiple second sliders 5b3 corresponding to the second slide groove 5b1 on the second connecting block 5b2 are used to facilitate the connection between the two so as to move in an orderly manner and provide support for the second connecting block 5b2 to prevent it from falling due to gravity. Multiple second sliders 5b3 are provided to prevent one end of the second connecting block 5b2 from being too heavy and causing tilting, affecting the transmission effect.

[0058] Further:

[0059] The second slider 5b3 is cylindrical and has a thread at one end. One end of the second slider 5b3 is passed through the outside of the vertical plate 5b and is provided with a clamping piece 5b5 and nuts 5b6 of the same number and corresponding to the second slider 5b3. The end of the clamping piece 5b5 close to the vertical plate 5b is made of flexible graphite material.

[0060] Based on the above embodiments, the technical problem that this application aims to solve is how to facilitate the disassembly of the second connecting block for maintenance. Figure 12 As shown, the present application arranges the second slider 5b3 into a cylindrical shape and makes it pass through the outer side of one end of the vertical plate 5b, thereby facilitating the passing of the clamping piece 5b5 and the clamping of the nut 5b6 with the thread. The end of the clamping piece 5b5 close to the vertical plate 5b is made of flexible graphite material, and the self-lubricating property provided by the flexible graphite material prevents it from preventing the second connecting block 5b2 from sliding. It should be noted that the thread is a prior art and is therefore not drawn in the figure.

[0061] Further:

[0062] The first transmission mechanism 3 includes a first transmission block 3b, a first connecting rod 3c and a first elastic member 3d; the first transmission block 3b is movably arranged inside the first cavity 2a and the first connecting block 3a is arranged on the outer surface of the first transmission block, and the first transmission block 3b is respectively provided with first slots 3b1 at the upper and lower ends; the first connecting rod 3c is arranged inside the first slot 3b1 and extends upward, and the top of the first connecting rod 3c is provided with a second slot 3c1 connected to the first linear drive 4; the first elastic member 3d is arranged at the bottom end of the first transmission block 3b, and the two ends of the first elastic member 3d are respectively connected to the fixed support rod 2 and the first transmission block 3b.

[0063] Based on the above embodiments, the technical problem that the present application intends to solve is how the first transmission connection mechanism performs transmission. Figure 3 and Figure 5As shown in the figure, in this application, the first linear driver 4 pushes the first connecting rod 3c connected to it through the second slot 3c1, so that the first connecting rod 3c passes through the first slot 3b1 to push the first transmission block 3b to drive the first connecting block 3a to be connected. The first elastic member 3d will be subjected to a thrust force and be compressed, so that when the first linear driver 4 stops pushing, it can be reset by the elastic force.

[0064] Furthermore:

[0065] A third chute 3b2 is further provided at the bottom end of the first transmission block 3b. A plurality of uniformly distributed limiting slots 3b3 are further provided around the third chute 3b2. A second elastic member 3b4 and a push plate 3b5 located at the bottom end of the second elastic member 3b4 are provided inside the third chute 3b2. The push plate 3b5 is provided with limiting blocks 3b6 having the same number as and corresponding to the limiting slots 3b3 one by one. A second connecting rod 3b7 is further provided below the push plate 3b5. An internal thread hole 2c is further provided at the bottom end of the first connecting rod 3c. A bolt 2c1 and a gasket 2c2 corresponding to the internal thread hole 2c are provided on the internal thread hole 2c.

[0066] Based on the above embodiments, the technical problem that this application wants to solve is how to prevent the first elastic member 3d from being inconvenient to reset after long-term use. For this reason, as Figure 7 and Figure 9 shown in the figure, this application adjusts the number of gaskets 2c2 so that the bolt 2c1 can rotate different distances to strengthen the force of pushing the second connecting rod 3b7, so that the push plate 3b5 pushes the second elastic member 3b4 to change its elastic force, so that the other values that prevent the first elastic member 3d from changing for a long time by the compression of the second elastic member 3b4 are increased, and its service life is extended. The limiting slots 3b3 and the limiting blocks 3b6 are to prevent the second elastic member 3b4 connected to the push plate 3b5 from rotating together, thereby reducing the service life of the second elastic member 3b4. It should be noted that a fixing device for abutting against the bolt 2c1 should also be provided at its bottom end to prevent it from slowly rotating and falling off due to the elastic force.

[0067] Furthermore:

[0068] The length of the first transmission block 3b is greater than the length of the first chute 2b, and a cap 3b8 is further provided at the top end of the first transmission block 3b. A first through hole 3b9 corresponding to the first connecting rod 3c is provided on the cap 3b8.

[0069] Based on the above embodiments, the technical problem that this application wants to solve is how to strengthen the sealing effect of the first transmission block 3b to prevent a large amount of materials from entering and affecting the transmission, and at the same time prevent the first connecting rod 3c from tilting. For this reason, as Figure 8As shown, in the present application, the length of the first transmission block 3b is made greater than the length of the first sliding groove 2b, so that the material cannot enter the fixed support rod 2 through the first sliding groove 2b by means of the first transmission block 3b. Then, one end of the first connecting rod 3c is fixed by means of the cap 3b8 and the first through hole 3b9 to prevent its inclination from affecting the transmission effect.

[0070] Furthermore:

[0071] Two feeding ports 1a are provided at the top end of the housing 1, and a funnel 1a1 in the shape of an arch bridge is provided on the two feeding ports 1a.

[0072] Based on the above embodiments, the technical problem that the present application wants to solve is how to prevent the first linear actuator 4 from affecting the transmission. For this purpose, as Figure 1 and 2 shown, in the present application, two feeding ports 1a are provided at the top end of the housing 1 and a funnel 1a1 with an arch-shaped bottom end is provided on the two feeding ports 1a, so as to facilitate the placement of the first linear actuator 4 and prevent the first linear actuator 4 from affecting the transmission.

[0073] Furthermore:

[0074] The housing 1 is divided into a top cover and a bottom sleeve 1d. A conical guide plate 1c1 is provided at the bottom end of the top cover and located below the two feeding ports 1a. A collection box 1d1 is also provided directly below the guide plate 1c1 on the bottom sleeve 1d. A plurality of second reinforcing ribs 1d2 connected to the bottom sleeve 1d are provided on the peripheral wall of the collection box 1d1 and a magnet is provided inside it.

[0075] Based on the above embodiments, the technical problem that the present application wants to solve is how to facilitate... For this purpose, as Figure 1 and Figure 2 shown, in the present application, the housing 1 is divided into a top cover and a bottom sleeve 1d to facilitate the cleaning of the collection box 1d1. Then, the material slides down along the guide plate 1c1 by inertia through the plurality of second reinforcing ribs 1d2 due to the guide plate 1c1, and the magnetic impurities are adsorbed into the collection box 1d1 through the gap left between the collection box and the guide plate 1c1 by the magnetic force.

[0076] Furthermore:

[0077] Two uniformly distributed handles 1e are provided on the housing 1.

[0078] Based on the above embodiments, the technical problem that the present application wants to solve is how to facilitate the grasping of the housing 1. For this purpose, as Figure 1 shown, in the present application, two uniformly distributed handles 1e are provided on the housing 1 to facilitate its grasping.

[0079] The above embodiments merely represent one or several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention shall be subject to the appended claims.
