Description

Technical Field

[0001] The utility model relates to the technical field of metal sheet processing, in particular to a feeding device for the production of the front baffle of an injection molding machine. Background Technique

[0002] An injection molding machine is the main molding equipment for making various shaped plastic products by using thermoplastic or thermosetting plastics with a plastic molding die. When the injection molding machine is in production and processing, the front end of its chassis is set as an open structure, and then it is closed by configuring a front baffle. In this way, the equipment inside the chassis can be protected during production, and at the same time, when overhauling and maintaining, only the front baffle needs to be disassembled to facilitate the inspection and repair of the equipment inside the chassis.

[0003] The front baffle of an injection molding machine is formed by cutting, punching, and stamping metal sheets. Among them, a laser cutting machine is one of the commonly used cutting equipment for metal sheets. When producing the front baffle, the metal sheet is lifted and transferred to the laser cutting machine by a vacuum suction cup lifting device. However, when the existing vacuum suction cup lifting device adsorbs the metal sheet, if there are impurities on the surface of the metal sheet, it will affect the adsorption state of the vacuum suction cup, resulting in a weakening of the adsorption force of the vacuum suction cup, which is not conducive to the stable lifting and feeding of the sheet, and there are certain safety hazards. Based on this, in order to further improve the production safety of the front baffle of an injection molding machine, a feeding device for the production of the front baffle of an injection molding machine is provided. Content of the Utility Model

[0004] The purpose of the utility model is to provide a feeding device for the production of the front baffle of an injection molding machine in order to solve the problems in the above background.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A feeding device for the production of the front baffle of an injection molding machine includes a feeding component composed of a hanger body and vacuum suction cups. The vacuum suction cups are fixedly installed on each cross arm of the hanger body. An impurity removal component is arranged on each cross arm of the hanger body. The impurity removal component is distributed on one side of the vacuum suction cups. The impurity removal component is used for removing impurities on the surface of the position where the metal sheet contacts the vacuum suction cups.

[0006] The impurity removal component includes a cleaning unit, a swinging unit, and a friction reduction unit.

[0007] The cleaning unit is used for blowing air on the surface of the metal sheet to achieve a cleaning operation.

[0008] The swinging unit is used for realizing the reciprocating swing of the cleaning unit to further improve the cleaning effect of the cleaning unit.

A through hole for the vertical movement of the telescopic rod is opened inside the fixed seat, and a ball is installed inside the fixed seat and extends into the through hole and is slidably connected to the spiral corrugated guide groove. The telescopic rod rotates synchronously and reciprocally during the up and down movement through the cooperation of the spiral corrugated guide groove and the ball.

[0015] As a further solution of the present utility model: The bottom horizontal height of the arc-shaped blowing plate is lower than the bottom horizontal height of the vacuum suction cup in the initial state;

[0016] When the feeding assembly moves downwards and approaches the metal plate, the arc-shaped blowing plate contacts the metal plate first and moves upwards under the extrusion force of the metal plate.

[0017] As a further solution of the present utility model: The resistance reduction unit includes a telescopic spring, an annular gasket, and a resistance reduction ball;

[0018] There are two annular gaskets. The two annular gaskets are rotatably sleeved on the outer side of the telescopic rod and are located below the fixed seat.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 to 3 , in the embodiment of the present invention, a feeding device for the production of the front baffle of an injection molding machine includes a feeding assembly 1 composed of a hanger body 101 and a vacuum suction cup 102. The vacuum suction cup 102 is fixedly installed on each cross arm of the hanger body 101. An impurity removal assembly 2 is provided on each cross arm of the hanger body 101. The impurity removal assembly 2 is distributed on one side of the vacuum suction cup 102. The impurity removal assembly 2 is used to perform impurity removal operations on the surface of the position where the metal plate contacts the vacuum suction cup 102;

[0031] The impurity removal assembly 2 includes a cleaning unit, a swinging unit, and a drag reduction unit;

[0032] The cleaning unit is used to blow air on the surface of the metal plate to achieve a cleaning operation. The swinging unit is used to achieve the reciprocating swing of the cleaning unit to further improve the cleaning effect of the cleaning unit. The drag reduction unit is used to reduce the frictional resistance when the cleaning unit reciprocates;

[0033] The cleaning unit includes a fixed seat 201, a telescopic rod 202, a limit top block 203, an arc-shaped blowing plate 204, an air inlet pipe 205, and blowing holes 206;

[0034] The fixed seat 201 is fixedly installed on the outer side of the cross arm of the hanger body 101. The telescopic rod 202 is vertically slidably installed inside the fixed seat 201 and penetrates through the upper and lower ends of the fixed seat 201. The limit top block 203 is fixed to the top end of the telescopic rod 202. The arc-shaped blowing plate 204 is fixed to the bottom end of the telescopic rod 202, and the arc-shaped blowing plate 204 is distributed on one side of the vacuum suction cup 102;

[0035] The air inlet pipe 205 is fixed to one end of the top of the fixed seat 201. The blowing holes 206 are opened on the side of the arc-shaped blowing plate 204 close to the vacuum suction cup 102 and near the bottom position of the arc-shaped blowing plate 204. High-pressure air is blown onto the surface of the metal plate through the air inlet pipe 205, the inner cavity of the arc-shaped blowing plate 204, and the blowing holes 206 to achieve the cleaning operation of the surface of the metal plate;

[0036] The swinging unit includes a spiral corrugated guide groove 207;

[0037] The spiral corrugated guide groove 207 is opened on the outer side of the telescopic rod 202. A through hole for the vertical movement of the telescopic rod 202 is opened inside the fixed seat 201, and a ball is installed inside the fixed seat 201 and extends into the through hole and is slidably connected to the spiral corrugated guide groove 207. The cooperation of the spiral corrugated guide groove 207 and the ball enables the telescopic rod 202 to rotate synchronously and reciprocally during the up and down movement;

[0038] When the arc-shaped blowing plate 204 is in the initial state, the bottom horizontal height is lower than the bottom horizontal height of the vacuum suction cup 102;

[0039] When the feeding assembly 1 moves downwards and approaches the metal plate, the arc-shaped blowing plate 204 contacts the metal plate first and moves upwards under the extrusion force of the metal plate;

[0040] A chassis 103 is installed at the upper end of the hanger body 101. A vacuum pump and an air pump are installed inside the chassis 103. The vacuum suction cup 102 and the air inlet pipe 205 are respectively communicated with the vacuum pump and the air pump through hoses and air valves.

[0041] In this embodiment, it should be noted that: a cavity structure communicating with the air inlet pipe 205 and the blowing holes 206 is formed inside the arc-shaped blowing plate 204;

[0042] When performing the cutting process of the front baffle raw material, the hanger body 101 is integrally lifted and approached the metal plate by an external lifting device. When the arc-shaped blowing plate 204 is about to approach the metal plate, the air path between the air pump and the air inlet pipe 205 is controlled to be conducted by an external controller. At this time, high-pressure air is ejected through the air inlet pipe 205, the inner cavity of the arc-shaped blowing plate 204, and the blowing holes 206. When the arc-shaped blowing plate 204 contacts the surface of the metal plate, the high-pressure air ejected from the blowing holes 206 impacts the surface of the metal plate, so that the impurities on the surface of the metal plate are blown away, thus realizing the cleaning operation of the surface of the metal plate;

[0043] Moreover, as the hanger body 101 continues to move downwards as a whole, the arc-shaped blowing plate 204 is subjected to the extrusion force from the metal plate. This extrusion force is transmitted to the telescopic rod 202, causing the telescopic rod 202 to move upwards relative to the fixed seat 201. Since the spiral corrugated guide groove 207 on the surface of the telescopic rod 202 is slidably connected to the ball inside the fixed seat 201, the telescopic rod 202 will rotate synchronously and reciprocally during the upward movement, and then drive the arc-shaped blowing plate 204 to swing reciprocally, so that the airflow ejected from the blowing holes 206 can blow the surface of the metal plate in all directions, thereby further improving the cleaning effect;

[0044] Finally, the vacuum suction cup 102 contacts the surface of the cleaned metal plate, effectively improving the adsorption effect between the vacuum suction cup 102 and the surface of the metal plate, and making the overall adsorption force of the device stronger.

[0045] Please refer to with emphasis Figures 1 to 3, the drag reduction unit includes a telescopic spring 208, an annular gasket 209, and drag reduction balls 210;

[0046] There are two annular gaskets 209. The two annular gaskets 209 are rotatably sleeved on the outer side of the telescopic rod 202 and are located below the fixed seat 201. The telescopic spring 208 is sleeved on the outer side of the telescopic rod 202 and is located between the two annular gaskets 209. The telescopic spring 208 is used to provide a reset elastic force for the upwardly moving arc-shaped blowing plate 204. The annular gasket 209 is used to prevent relative sliding friction between the ends of the telescopic spring 208 and the fixed seat 201 and the arc-shaped blowing plate 204 when the telescopic rod 202 rotates;

[0047] The drag reduction balls 210 are rotatably installed on the inner side of the arc-shaped blowing plate 204 and protrude from the bottom of the arc-shaped blowing plate 204. The arc-shaped blowing plate 204 contacts the surface of the metal plate through the drag reduction balls 210, which is used to reduce the frictional resistance when the arc-shaped blowing plate 204 rotates;

[0048] A plurality of drag reduction balls 210 are uniformly arranged along the arc track of the arc-shaped blowing plate 204. A spherical groove for the drag reduction balls 210 to roll is formed on the inner side of the arc-shaped blowing plate 204.

[0049] In this embodiment: The bottom of the arc-shaped blowing plate 204 contacts the surface of the metal plate through the drag reduction balls 210. In this way, when the arc-shaped blowing plate 204 reciprocally rotates, the drag reduction balls 210 roll, which can effectively reduce the rotational resistance of the arc-shaped blowing plate 204;

[0050] And during the upward movement of the arc-shaped blowing plate 204, the telescopic spring 208 is stressed and contracts, and the annular gasket 209 can support the upper and lower ends of the telescopic spring 208 to prevent relative friction between the ends of the telescopic spring 208 and the top of the arc-shaped blowing plate 204 and the bottom of the fixed seat 201.

[0051] Please refer specifically to Figures 1 to 3 , the inner wall diameter of the arc-shaped blowing plate 204 is greater than the maximum outer wall diameter of the vacuum suction cup 102. The blowing holes 206 are inclined downward in the direction towards the vacuum suction cup 102, and a plurality of blowing holes 206 are uniformly arranged along the arc track of the arc-shaped blowing plate 204.

[0052] In this embodiment: The structure that the inner wall diameter of the arc-shaped blowing plate 204 is greater than the maximum outer wall diameter of the vacuum suction cup 102 is used to provide space for the rotation of the arc-shaped blowing plate 204, so that the arc-shaped blowing plate 204 will not collide with the vacuum suction cup 102 when reciprocally swinging;

[0053] The blowing holes 206 are in an inclined downward state towards the direction of the vacuum suction cup 102, so that the air flow ejected from the blowing holes 206 can be directed towards the surface of the metal sheet. Combining with the structure of the multiple blowing holes 206 and the reciprocating swing of the arc-shaped blowing plate 204, the blowing and cleaning operation on the surface of the metal sheet can be realized.

[0054] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
