Description

Technical Field

[0001] The utility model relates to the technical field of lampshade manufacturing equipment, and particularly relates to a gate cutting station for producing lampshades. Background Art

[0002] As a common lighting accessory, a lampshade is designed to be installed around a light source or directly cover the bulb. Its core function is to adjust and control the divergence of light, achieving the concentration or diffusion of light to achieve an ideal lighting effect. It not only enhances the lighting efficiency but also, with its environmental beautification characteristics, becomes an essential element in the decoration of homes, commercial places, and public spaces.

[0003] During the injection molding production of large-sized plastic lampshades, the mold design needs to include multiple feeding channels to ensure full molding of the lampshade. The solidified plastic part left by these channels after molding is the gate. Traditionally, the removal of the gate relies on manual operation, and the operator manually cuts the gate on the lampshade using scissors or a blade. This method not only has low work efficiency but also has certain safety risks. In addition, the trimmed gates are scattered on the workbench or the ground, bringing an additional burden to the subsequent cleaning work and reducing the production efficiency of the lampshade. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a gate cutting station for producing lampshades in view of the current situation of the prior art.

Specific Embodiment

[0024] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0025] As Figures 1 to 3 shown, a gate-cutting station for producing a lamp shade of the present invention includes: a machine platform 1, which has a semi-closed chamber; a support frame 2, which is arranged inside the machine platform 1, and the support frame 2 divides the chamber into a working cavity 3 and a storage cavity 4; a fixed seat 5, which is connected to the support frame 2 and is located in the working cavity 3, and is used to place the lamp shade 7 with the gate 8 to be cut; a cutting knife 6, which is connected in the working cavity 3 and can move along the outer contour of the lamp shade 7, so as to cut off the gate 8 on the lamp shade 7, and the gate 8 can fall into the storage cavity 4 after being separated from the lamp shade 7.

[0026] The lamp shade 7 to be trimmed is placed on the fixed seat 5, and the gate 8 is distributed along the outer edge of the lamp shade 7. During operation, the cutting knife 6 automatically moves along the outer contour of the lamp shade 7, and precisely peels off the gate 8 from the lamp shade 7. Subsequently, the cut-off gate 8, under the guidance of gravity, passes through the support frame 2 and naturally falls into the storage cavity 4 below. Once the gate 8 of the lamp shade 7 is trimmed, the cutting knife 6 will retract to the initial position along the preset path. At this time, the lamp shade 7 on the fixed seat 5 is replaced, and the cutting knife 6 is started again, and the trimming operation is performed along the contour of the lamp shade 7 until all the lamp shades 7 of the same batch are completely processed.

[0027] In this solution, by configuring a cutting knife 6 on the machine platform 1 that can move freely along the outer contour of the lamp shade 7, the trimming of the gate 8 is automatically completed, significantly reducing the complexity of manual trimming and accelerating the processing flow of the gate 8. In addition, the machine platform 1 is internally provided with a storage cavity 4 to immediately collect the gate 8 fragments generated by trimming, effectively reducing the burden of subsequent cleaning work, and overall promoting the efficiency and smoothness of the production of the lamp shade 7.

[0028] This solution further includes: two first driving members 9 arranged longitudinally on the machine table 1, with a first moving block 11 provided on the two first driving members 9; a second driving member 10, which is horizontally connected inside the machine table 1, the end of the second driving member 10 is connected to the first moving block 11, and a second moving block 12 is provided on the second driving member 10; a connecting frame 13, which is connected to the second moving block 12; a third driving member 14, which is vertically connected to the connecting frame 13, and the cutting knife 6 is connected to the output end of the third driving member 14 for driving the cutting knife 6 to move in the vertical direction.

[0029] The first driving member 9, the second driving member 10, and the third driving member 14 are preferably linear guide rails. The first driving member 9 drives the first moving block 11 to move longitudinally on the machine table 1, thereby realizing the movement process of the cutting knife 6 in the longitudinal direction of the machine table 1. The second driving member 10 drives the second moving block 12 to move horizontally along the machine table 1, thereby realizing the movement of the cutting knife 6 in the horizontal direction of the machine table 1. The coordinated operation of the first driving member 9 and the second driving member 10 ensures that the cutting knife 6 can accurately track and move along the outer contour of the lamp cover 7, realizing the precise separation of the gate 8 from the main body of the lamp cover 7. As for the third driving member 14, it is responsible for controlling the lifting movement of the cutting knife 6 in the vertical direction to meet the cutting requirements of the gate 8 at different heights or non-horizontal positions on the lamp cover 7, improving the comprehensiveness and flexibility of processing.

[0030] Preferably, the cutting knife 6 is a laser cutting head. The laser cutting head is a key component in the laser cutting equipment, which is directly related to the cutting quality and efficiency. The laser cutting head integrates optics, mechanics, and control systems. Its main function is to precisely focus the high-energy laser beam generated by the laser onto the surface of the workpiece, and through the high-density energy, the material is rapidly melted and evaporated, thereby completing the cutting process of the lamp cover 7 and the gate 8.

[0031] A through hole 15 is provided on the machine table 1. One end of the through hole 15 is communicated with the storage cavity 4, and the other end of the through hole 15 is communicated with the external space for guiding the exhaust gas in the chamber to be discharged.

[0032] During the process of the laser cutting head trimming the gate 8 of the lamp cover 7, harmful gases will be generated. If these gases are not effectively controlled, they will accumulate in the chamber and may leak into the workshop environment, posing a threat to the health of the operators. Therefore, the machine table 1 is specially designed with a through hole 15 connected to the chamber and extending outward. This design aims to connect to the air extraction pump system to effectively extract and discharge the gas in the chamber, thereby ensuring the air quality in the workshop and protecting the health of the operators.

[0033] The support frame 2 includes two first support columns 16 arranged horizontally and a plurality of second support columns 17 spaced between the two first support columns 16. The two first support columns 16 are connected to the inner side wall of the chamber, and the gap between the two second support columns 17 is for the gate 8 to pass through.

[0034] The connection method between the first support column 16 and the inner wall of the machine table 1 can be selected as welding or threaded fastening. Similarly, the connection between the multiple second support columns 17 and the first support column 16 can also adopt welding or threaded connection technology. The purpose of setting multiple second support columns 17 is to construct a diversion channel, so that the gate 8 trimmed from the working area can smoothly fall into the storage cavity 4, improving the smoothness and efficiency of the process.

[0035] A protective cover 18 corresponding to the first driving member 9 is connected to the upper end of the machine table 1. The protective cover 18 is sleeved outside the first driving member 9, and the openings of the two protective covers 18 are arranged oppositely, aiming to effectively isolate the interference and influence of the external environment on the first driving member 9 and ensure its normal operation.

[0036] Preferably, the storage cavity 4 is conical, which is used to gather the gates 8 in the storage cavity 4.

[0037] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, the directional indication will also change accordingly.

[0038] In addition, in the present invention, descriptions such as "first", "second", and "one" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0039] In the present invention, unless otherwise clearly specified and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement.
