Description

Technical Field

[0001] This utility model application relates to the technical field of cutting the gate of the lower trim strip of a refrigerator door, specifically the cutting of the gate of the lower trim strip of a refrigerator door. Background Technology

[0002] In the refrigerator manufacturing industry, the lower door trim is an important component of the refrigerator's appearance, serving not only an aesthetic purpose but also crucial functions such as protecting the internal structure and preventing cold air leakage. Gate removal is an essential step in the production of the lower door trim. The gate is the channel through which molten plastic enters the mold during injection molding; it must be removed after molding to obtain a trim product that meets design requirements.

[0003] Traditional gate removal methods rely primarily on manual operation, using tools such as cutters or scissors to manually remove the gate. This method has several drawbacks: First, manual operation makes it difficult to guarantee the accuracy and consistency of each removal, resulting in large dimensional deviations in the product, affecting assembly quality and aesthetic appearance; second, manual removal is inefficient, making it difficult to meet the needs of large-scale production, increasing production costs and time costs.

[0004] With the continuous development of automation technology, automated gate cutting equipment is gradually being applied to the production of refrigerator door trim strips. However, existing automated gate cutting equipment still has shortcomings in sorting functions. During the gate cutting process of refrigerator door trim strips, a large amount of waste and scrap is generated. If this waste and scrap are not cleaned up in time, it will not only affect the cleanliness of the production environment but may also damage the equipment and reduce its service life. Existing automated gate cutting equipment also has shortcomings in waste cleaning, often requiring regular manual cleaning. Utility Model Content

[0005] The purpose of this utility model application is to provide a refrigerator door trim gate cutting device with automatic sorting function. By setting a sorting component, the cut gate can be sent into a collection box, thus realizing the sorting of the cut gate.

[0006] To address the problems of existing technologies, this utility model application provides a refrigerator door trim gate cutting device with automatic sorting function, comprising: a frame; a sorting component for sorting the cut gates and disposed on one side of the frame; a separating component disposed on the top of the frame and used to separate two trims after mold making; a clamping component disposed above the separating component for fixing the trims; a cutting component disposed at the center of the frame for cutting the gates on the two trims; and a collection box disposed at the discharge end of the sorting component for collecting the cut gates; the sorting component includes a slide plate capable of vibration and transporting the cut gates to the collection box; the cutting component includes pneumatic shears capable of moving up and down and cutting the gates on the trims and capable of rotating to place the cut gates onto the slide plate.

[0007] Preferably, the sorting assembly includes connecting shafts disposed on both sides of the discharge end of the slide plate and capable of being rotatably connected to the frame, and a connecting block is also provided at the bottom of the side of the slide plate away from the connecting shafts.

[0008] Preferably, the sorting assembly includes two support plates mounted on a frame, and the sorting assembly also includes a tension spring capable of providing restoring force to the slide, one end of the tension spring being attached to a connecting block and the other end of the tension spring being attached to the support plate.

[0009] Preferably, the sorting assembly further includes a connecting frame disposed at the bottom of the slide plate, and the bottom of the connecting frame is rotatably provided with rollers. The sorting assembly also includes a vibration mechanism disposed at the bottom of the slide plate to make the slide plate vibrate.

[0010] Preferably, the vibration mechanism includes a first rotary drive member mounted on one of the support plates, the output end of the first rotary drive member being connected to an eccentric wheel, and the eccentric wheel cooperating with a roller.

[0011] Preferably, the separation assembly includes two separation plates that are slidably mounted on the frame and are capable of moving synchronously in the same direction or in opposite directions. The separation assembly also includes a synchronization mechanism located at the bottom of the separation plates and capable of driving the two separation plates to move closer or further apart. The clamping assembly is located at the center of the separation plates.

[0012] Preferably, the clamping assembly includes a first telescopic drive member fixed to the top of each of the two separation plates, and the output end of the first telescopic drive member is connected to a pressure plate capable of fixing the trim strip to the separation plates.

[0013] Preferably, the cutting assembly includes a second telescopic drive unit located at the center of the bottom of the frame. The output end of the second telescopic drive unit is connected to a lifting plate that can move up and down. The lifting plate is provided with two support frames. Each support frame is rotatably equipped with a pneumatic shear capable of cutting the gates of the two trim strips.

[0014] The advantages of this utility model application compared to the prior art are: This application includes a sorting assembly. One end of the sorting assembly is rotatably connected to the frame via a connecting shaft. A connecting frame is fixedly connected to the bottom of the slide plate, and a roller is rotatably mounted on the connecting frame. This roller cooperates with an eccentric wheel to form a transmission mechanism. When the first rotary drive is activated, it drives the eccentric wheel to rotate. Due to the special structure of the eccentric wheel, it generates periodic displacement changes during rotation, which in turn drives the cooperating roller to move up and down. This motion is transmitted to the slide plate through the connecting frame, causing the slide plate to vibrate up and down. This up-and-down vibration design allows the generated gate waste to smoothly slide off the slide plate and eventually fall into the collection box. This design effectively prevents the accumulation of cut gates on the slide plate, ensuring the continuity and efficiency of the production process. Attached Figure Description

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] Reference Figures 1-6 As shown, this utility model application provides a refrigerator door trim gate cutting device with automatic sorting function, including: a frame 1; a sorting component 2 for sorting the cut gates and disposed on one side of the frame 1; a separating component 3 disposed on the top of the frame 1 and used to separate two trims after mold making; a clamping component 4 disposed above the separating component 3 for fixing the trims; a cutting component 5 disposed at the center of the frame 1 for cutting the gates on the two trims; and a collection box 6 disposed at the discharge end of the sorting component 2 for collecting the cut gates. The sorting component 2 includes a slide plate 21 that can vibrate and transport the cut gates to the collection box 6; the cutting component 5 includes pneumatic scissors 54 that can move up and down and cut the gates on the trims and can rotate to place the cut gates onto the slide plate 21.

[0024] The two decorative strips, once molded, first enter the separation component 3, where they are secured by the clamping component 4. The separation component 3 separates the two strips, placing them as independent entities for subsequent individual fixing and gate removal operations. The pneumatic shears 54 in the removal component 5 move upwards to the gate location and cut off the gate on the strip. After removal, the pneumatic shears 54 move downwards, placing the removed gate onto the slide plate 21. The slide plate 21 vibrates, using the vibration to transport the gate to the collection box 6, achieving gate sorting and collection. The entire device, through the coordinated work of its components, completes a series of operations from strip separation, fixing, gate removal to gate sorting and collection.

[0025] The sorting assembly 2 includes connecting shafts 211 disposed on both sides of the discharge end of the slide plate 21 and rotatably connected to the frame 1. A connecting block 214 is also disposed on the bottom of the side of the slide plate 21 away from the connecting shafts 211. The sorting assembly 2 includes two support plates 216 mounted on the frame 1. The sorting assembly 2 also includes a tension spring 215 that provides restoring force to the slide plate 21. One end of the tension spring 215 is hung on the connecting block 214, and the other end of the tension spring 215 is hung on the support plate 216.

[0026] The sorting assembly 2 also includes a connecting frame 212 disposed at the bottom of the slide plate 21, and a roller 213 is rotatably disposed at the bottom of the connecting frame 212. The sorting assembly 2 also includes a vibration mechanism disposed at the bottom of the slide plate 21 and causing the slide plate 21 to vibrate. The vibration mechanism includes a first rotary drive 22 mounted on one of the support plates 216, and an eccentric wheel 221 is connected to the output end of the first rotary drive 22, and the eccentric wheel 221 cooperates with the roller 213.

[0027] When the device is started, the first rotary drive component 22 begins to work, and its output end drives the eccentric wheel 221 to rotate. Due to the eccentricity of the eccentric wheel 221, the distance between the outer contour of the eccentric wheel 221 and the roller 213 changes continuously during rotation. The slide plate 21 vibrates periodically under the combined action of the eccentric wheel 221 and the roller 213, as well as the tension spring 215. After the cut-off gate is placed on the slide plate 21, under the vibration of the slide plate 21, the gate moves along the surface of the slide plate 21 towards the discharge end and finally falls into the collection box 6, completing the gate sorting and collection process.

[0028] The separation assembly 3 includes two separation plates 31 that are slidably mounted on the frame 1 and can move synchronously in the same direction or in opposite directions. The separation assembly 3 also includes a synchronization mechanism 32 located at the bottom of the separation plates 31 and capable of driving the two separation plates 31 to move closer or further apart from each other. The clamping assembly 4 is located at the center of the separation plates 31.

[0029] The synchronizing mechanism 32 can be a cylinder or a motor-driven screw mechanism. The synchronizing mechanism 32 drives the two separating plates 31 to move synchronously in opposite directions, and the distance between the two separating plates 31 gradually increases. In this process, the two separating plates 31 act on the two trim strips respectively, gradually pulling the originally attached trim strips apart, thus achieving the separation of the trim strips.

[0030] The clamping assembly 4 includes a first telescopic drive member 41 fixed to the top of the two separation plates 31 respectively, and the output end of the first telescopic drive member 41 is connected to a pressure plate 42 that can be used to fix the trim strip to the separation plate 31.

[0031] When the trim strip is placed on the separation plate 31, the output end of the first telescopic drive member 41 extends out, pushing the pressure plate 42 to move downward. The pressure plate 42 gradually approaches the trim strip and finally presses on the trim strip, firmly fixing the trim strip to the separation plate 31.

[0032] The cutting component 5 includes a second telescopic drive 51 located at the center of the bottom of the frame 1. The output end of the second telescopic drive 51 is connected to a lifting plate 52 that can move up and down. Two support frames 53 are provided on the lifting plate 52. Each support frame 53 is rotatably equipped with a pneumatic shear 54 that can cut the gates of the two trim strips. A second rotary drive 55 that can drive the pneumatic shear 54 to rotate is also fixed on the support frame 53.

[0033] After the trim strips are separated by the separating component 3, the cutting component 5 begins to operate. The output end of the second telescopic drive 51 extends, pushing the lifting plate 52 upward. The lifting plate 52 drives the support frame 53 and the pneumatic shears 54 on the support frame 53 to rise together, so that the pneumatic shears 54 reaches the height where the trim strip gates are located. Then, the pneumatic shears 54 closes, cutting off the gates on the two trim strips. After the cutting is completed, the pneumatic shears 54 moves downward, so that the pneumatic shears 54 moves down to the slide plate 21. At this time, the second rotary drive 55 starts to operate, and its output end drives the pneumatic shears 54 to rotate, placing the cut gates onto the slide plate 21.

[0034] The above embodiments only illustrate one or more implementation methods of this utility model application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
