Description

Technical Field

[0001] This invention relates to the field of pillow manufacturing, and more particularly to an adjustable gel pillow injection production apparatus. Background Technology

[0002] When making a gel pillow, the process usually involves first laying a solidified gel layer with an insulating layer (which is a plastic film) in the lower mold. Then, the mixed raw materials are injected into the lower mold by manually controlling the machine. The mold is then closed, allowing the gel layer to combine with the raw materials and foam. After foaming is complete, the gel pillow is allowed to cool before being removed from the mold. The edges of the gel pillow are then trimmed, and finally, the details are finished and packaged.

[0003] When the machine is manually controlled to inject the mixed raw materials into the lower mold, the discharge port usually moves from one end of the lower mold to the other to fill the raw materials. However, when the discharge is controlled manually during the movement process, some raw materials will drip directly onto the surface and side walls of the lower mold. This not only wastes resources, but also affects the sealing between the upper and lower molds after the raw materials solidify on the lower mold, thus affecting product quality. In addition, the gel pillow raw materials are continuously exposed to the outside environment during the injection process, which will attract dust and impurities from the air, thus forming defects during the foaming process. This not only affects the appearance quality, but also reduces the mechanical strength and service life of the product. Summary of the Invention

[0004] To overcome the drawbacks of manual material control during the moving process, where some raw materials will drip directly onto the surface and sidewalls of the lower mold, resulting in resource waste, and the solidification of raw materials on the lower mold will affect the sealing between the upper and lower molds, thus affecting product quality, this invention provides an adjustable gel pillow injection production device.

[0008] To further explain, the upper mold is made of heat-insulating material.

[0009] To further explain, the sealing part of each movable rod is designed as a frustum shape.

[0010] To further explain, a limit groove is provided on the lower mold.

[0011] To further explain, the edge of the disc on each connecting rod is made of rubber.

[0012] To further explain, it also includes an extrusion ring; the lower side of the upper mold is provided with an extrusion ring for extruding the gel pillow isolation layer, and the extrusion ring is engaged with the limiting groove of the lower mold.

[0013] Further explanation: It also includes an extrusion block and a spring telescopic rod; the upper mold is provided with several movable slots; an extrusion block is slidably connected in each movable slot; a second inclined surface is provided on each extrusion block; a number of first inclined surfaces are provided on the extrusion ring, and the first inclined surfaces are fitted with adjacent second inclined surfaces; a number of spring telescopic rods are fixedly connected between the extrusion ring and the upper mold, each spring telescopic rod is embedded in the upper mold, and the telescopic end of the spring telescopic rod is fixedly connected to the extrusion ring.

[0015] The beneficial effects of the present invention are as follows: The present invention realizes the control of the separation time between the sealing part and the adjacent liquid outlet by controlling the first driving component to drive the connecting plate and the movable rod to move up and down, thereby controlling the content of raw material flowing into the lower mold. This eliminates the need for manual movement to control the discharge, avoids raw material dripping onto the surface and side walls of the lower mold, and reduces resource waste. At the same time, by injecting the raw material into the lower mold after mold closing, it avoids excessive contact between the raw material and air, which would affect the quality of the final product.

[0016] The lower end of the movable rod adsorbs the four corners of the upper surface of the gel pillow, thereby causing the gel pillow to detach from the lower mold below, reducing the time required for manual demolding and improving production efficiency.

[0017] By setting a limiting groove on the lower mold, more raw material can overflow from the contact area between the upper and lower molds into the limiting groove of the lower mold, so that the rough edges of the gel pillow after foaming are regular, making manual trimming more precise, reducing product damage caused by improper trimming, and thus reducing the scrap rate.

[0018] The extrusion ring compresses the isolation layer, making it fit more closely to the inner surface of the lower mold. This reduces the pressure exerted on the gel pillow by the overlapping isolation layers during the gel pillow foaming process. At the same time, the taut isolation layer is smoother, thus reducing the formation of wrinkles between the isolation layer and the gel pillow and improving the aesthetics of the gel pillow surface.

Detailed Implementation

[0033] Example 1

[0034] An adjustable gel pillow dispensing production apparatus, such as Figures 1-7As shown, the device includes a fixed base 1, an upper mold 2, a lower mold 3, and a lifting assembly. The lower mold 3 is mounted on the fixed base 1. The lifting assembly is installed on the fixed base 1. The upper mold 2 is connected to the lifting assembly, which drives the upper mold 2 to move up and down, thereby separating and closing the upper mold 2 and the lower mold 3. It also includes a drive assembly, movable rods 4, and auxiliary components. The drive assembly is installed on the upper mold 2. Five movable rods 4 are connected to the drive assembly. The upper mold 2 has a hollow structure and is equipped with a glue injector 222 for adding glue into the upper mold 2. Raw materials used for gel pillow foaming; the upper mold 2 is provided with five liquid outlets 2001; each movable rod 4 is provided with a sealing part 4001 on its lower side, and each sealing part 4001 is engaged with the adjacent liquid outlet 2001. The movable rod 4 is driven to move up and down by the drive assembly, so that the sealing part 4001 of the movable rod 4 is separated from the liquid outlet 2001. The glue injector 222 adds new raw materials into the upper mold 2, so that the raw materials in the upper mold 2 are injected into the lower mold 3 below from the liquid outlet 2001 of the upper mold 2, thereby realizing the addition of raw materials; auxiliary components are installed on the upper mold 2.

[0035] The lifting assembly includes a slide rail 101, an electric slider 102, and a connecting block 103; two left-right symmetrical slide rails 101 are fixedly connected to the fixed base 1; an electric slider 102 is slidably connected to each slide rail 101; a connecting block 103 is fixedly connected between the two electric sliders 102, and the upper mold 2 is fixedly connected to the connecting block 103.

[0036] The drive assembly includes a first drive component 201 and a connecting plate 202; four first drive components 201 are fixedly connected to the upper mold 2, and the first drive components 201 are electric push rods; the telescopic ends of all the first drive components 201 are fixedly connected to the connecting plate 202, and each movable rod 4 is fixedly connected to the connecting plate 202.

[0037] The auxiliary components include a fixing block 301, a second driving member 302, a first connecting pipe 303, a connecting rod 304, and a second connecting pipe 305; each movable rod 4 is provided with a connecting groove 4002; four fixing blocks 301 are fixedly connected to the connecting plate 202; a second driving member 302 is fixedly connected to each fixing block 301, and the second driving member 302 is an electric push rod; four first connecting pipes 303 are fixedly connected to each connecting plate 202, and each first connecting pipe 303 communicates with the connecting groove 4002 of the adjacent movable rod 4; each Each output end of the second drive unit 302 is fixedly connected to a connecting rod 304, and each connecting rod 304 is located in the connecting groove 4002 of the adjacent movable rod 4; each connecting rod 304 is slidably connected to the adjacent first connecting pipe 303; each connecting rod 304 is provided with a disc 30401 on its lower side, and the inner diameter of the end of each movable rod 4 away from the sealing part 4001 is larger than the diameter of the adjacent disc 30401; a second connecting pipe 305 is connected between two adjacent first connecting pipes 303, and the second connecting pipe 305 is connected to the external pump.

[0038] The upper mold 2 is made of heat-insulating material.

[0039] Several movable rods 4 are evenly distributed in the upper mold 2, which facilitates the flow of raw materials from multiple parts of the upper mold 2 into the lower mold 3, thereby shortening the flow distance of the raw materials in the lower mold 3, making the raw materials more quickly and evenly distributed in the entire mold, shortening the time of the entire foaming process, and improving production efficiency.

[0040] Each movable rod 4 has a sealing part 4001 that is truncated cone-shaped, so that when the raw material flows downward from the liquid outlet 2001, the raw material will spread outward along the upper surface of the sealing part 4001, further improving the filling uniformity of the raw material.

[0041] The lower mold 3 is provided with a limiting groove 3001, which makes the rough edges of the gel pillow after foaming regular, making manual trimming more precise, reducing product damage caused by improper trimming, and thus reducing the scrap rate.

[0042] The edge of the disc 30401 of each connecting rod 304 is made of rubber to improve the sealing effect of the disc 30401 on the connecting groove 4002 of the movable rod 4, and prevent the gel pillow from entering the connecting groove 4002 through the gap between the disc 30401 and the movable rod 4 during the foaming process.

[0043] When manually controlling the material discharge during the moving process, some raw materials will drip directly onto the surface and sidewalls of the lower mold 3, which not only leads to resource waste, but also affects the sealing between the upper mold 2 and the lower mold 3 after the raw materials solidify on the lower mold 3, affecting product quality. At the same time, the gel pillow raw materials are continuously exposed to the outside world during the injection process, which will adhere to dust and impurities in the air, forming defects during the foaming process.

[0044] The working steps of this embodiment are as follows:

[0045] First, control the electric slider 102 to move the connecting block 103 and the upper mold 2 upward, so that the upper mold 2 and the lower mold 3 are separated until the upper mold 2 and the lower mold 3 are at a suitable distance, so that the gel layer 5 with the isolation layer 5001 can be manually laid in the lower mold 3. After the laying is completed, control the electric slider 102 to move the connecting block 103 and the upper mold 2 downward, so that the upper mold 2 and the lower mold 3 are in a closed state, and control the glue injector 222 to deliver the raw material into the upper mold 2.

[0046] The second step involves controlling the first driving component 201 to move the connecting plate 202 and the movable rod 4 downwards until the sealing part 4001 of the movable rod 4 separates from the adjacent liquid outlet 2001. The raw material will then flow directly out of the liquid outlet 2001 and eventually into the lower mold 3 below. It should be noted that the raw material used for foaming requires specific temperature and pressure conditions to foam. Therefore, the raw material will not foam when it is in the upper mold 2. According to production needs, the first driving component 201 is controlled to move the connecting plate 202 and the movable rod 4 upwards to return to the initial state. This eliminates the need for manual movement to control the discharge, preventing the raw material from dripping onto the surface and sidewalls of the lower mold 3, thus reducing resource waste. At the same time, by injecting the raw material into the lower mold 3 after mold closing, excessive contact between the raw material and air is avoided, which could affect the final product quality.

[0047] Meanwhile, when the raw material flows into the lower mold 3 from the outlet 2001 of the upper mold 2, since the movable rod 4 is evenly distributed in the upper mold 2, the raw material will flow into the lower mold 3 from multiple parts of the upper mold 2 during the discharge process. This shortens the flow distance of the raw material in the lower mold 3, allowing the raw material to be distributed more quickly and evenly throughout the mold, shortening the time of the entire foaming process and improving production efficiency. By setting the sealing part 4001 of the movable rod 4 to a frustum shape, when the raw material flows downward from the outlet 2001, the raw material will diffuse along the upper surface of the sealing part 4001 to the surrounding areas, further improving the filling uniformity of the raw material.

[0048] The third step involves foaming under set temperature and pressure. Once foaming and cooling are complete, the gel pillow is fully cured. At this point, the second drive unit 302 is controlled to move the adjacent connecting rod 304 upwards until the disc 30401 of the connecting rod 304 moves to a position within the connecting groove 4002 larger than the aperture of the disc 30401. At this point, the connecting groove 4002 is connected to the first connecting pipe 303, the second connecting pipe 305, and the external pump. The external pump is then controlled to draw air outwards, creating a suction force at the lower end of the movable rod 4 to adsorb the foamed gel pillow's upper surface. It is important to note that the foamed and cured gel pillow has good elasticity and resilience; it quickly returns to its original shape after being stretched during removal. Therefore, the suction force will not damage the gel pillow. Meanwhile, the electric slider 102 drives the connecting block 103 and the upper mold 2 to move upward together. The lower end of the movable rod 4 adsorbs the four corners of the upper surface of the gel pillow, thereby causing the gel pillow to separate from the lower mold 3 below. This reduces the time required for manual demolding and improves production efficiency. At the same time, before the upper mold 2 and the lower mold 3 separate, the volatile organic compounds generated inside the upper mold 2 and the lower mold 3 due to the foaming process will be sucked to the outside through the connecting groove 4002 of the movable rod 4 by the second connecting pipe 305, thereby avoiding the impact on the human body when the gel pillow is manually picked up, causing discomfort. When the upper mold 2 moves the gel pillow upward to a suitable distance, the external pump stops sucking, allowing the gel pillow to fall downward naturally. The gel pillow can then be collected and processed manually.

[0049] It is important to note that during the gel pillow foaming process, the contact area between the upper mold 2 and the lower mold 3 cannot be completely sealed. Therefore, some raw material will overflow from these tiny gaps under high pressure, forming burrs. However, due to the irregularity of the burrs, manual trimming can easily lead to over-trimming or under-trimming. To solve this problem, when the raw material is injected into the lower mold 3, the dosage is increased based on the original content. This allows more raw material to overflow from the contact area between the upper mold 2 and the lower mold 3 into the limiting groove 3001 of the lower mold 3 during the gel pillow foaming process. As a result, the burrs on the edge of the gel pillow after foaming are regular, making manual trimming more precise, reducing product damage caused by improper trimming, and thus reducing the scrap rate.

[0050] Example 2

[0051] Based on Example 1, such as Figures 1-3 and Figures 7-12 As shown, it also includes an extrusion ring 401; the extrusion ring 401 is provided on the lower side of the upper mold 2, and the extrusion ring 401 is fitted into the limiting groove 3001 of the lower mold 3.

[0052] It also includes an extrusion block 501 and a spring telescopic rod 502; the upper mold 2 is provided with two left-right symmetrical movable grooves 2002; an extrusion block 501 is slidably connected in each movable groove 2002; a second inclined surface 50101 is provided on each extrusion block 501; the extrusion ring 401 is provided with two left-right symmetrical first inclined surfaces 40101, and the first inclined surface 40101 is fitted with the adjacent second inclined surface 50101; a number of spring telescopic rods 502 are fixedly connected between the extrusion ring 401 and the upper mold 2, each spring telescopic rod 502 is embedded in the upper mold 2, and the telescopic end of the spring telescopic rod 502 is fixedly connected to the extrusion ring 401.

[0053] It also includes a rubber ring 601; the upper mold 2 is fixed with the rubber ring 601.

[0054] The working principle of this embodiment is as follows:

[0055] When the gel layer 5 with the isolation layer 5001 is manually laid into the lower mold 3, the side of the gel pillow that contacts the neck of the human body has an irregular concave-convex shape. Therefore, the bottom shape of the lower mold 3 will also change accordingly. However, when the gel layer 5 with the isolation layer 5001 is manually laid into the lower mold 3, due to the special shape of the bottom of the lower mold 3, the adjacent parts of the isolation layer 5001 will be stacked together, resulting in some parts of the isolation layer 5001 being thicker than other parts. As a result, during the foaming process of the gel pillow, the stacked parts of the isolation layer 5001 will squeeze the gel pillow, causing some parts of the gel pillow to be concave inward, thus affecting the overall appearance of the gel pillow.

[0056] In the first step of Example 1: when the upper mold 2 and the lower mold 3 are in a closed state, the upper mold 2 will drive the extrusion ring 401 to move downward and extrude the lower isolation layer 5001. This causes the isolation layer 5001 above the limiting groove 3001 of the lower mold 3 to be gradually pressed into the limiting groove 3001. Since the gel layer 5 has a certain weight, the isolation layer 5001 is pulled by the extrusion ring 401 and the gel layer 5. The isolation layer 5001 between the extrusion ring 401 and the gel layer 5 will be taut, so that the isolation layer 5001 is more closely attached to the inner surface of the lower mold 3. This reduces the degree of compression of the gel pillow by the interlayered isolation layers 5001 during the gel pillow foaming process. At the same time, the taut isolation layer 5001 is smoother, thereby reducing the formation of wrinkles between the isolation layer 5001 and the gel pillow and improving the aesthetics of the gel pillow surface.

[0057] Meanwhile, when the gel pillow finishes foaming and cooling, the upper mold 2 moves the gel pillow upward. Since the extrusion ring 401 is embedded in the limiting groove 3001 of the lower mold 3, the extrusion ring 401 will move the burrs located in the limiting groove 3001 upward together, thereby supporting the edge of the gel pillow and improving the demolding effect of the movable rod 4 on the entire gel pillow.

[0058] Furthermore, as the upper mold 2 and the lower mold 3 gradually come into contact, the extrusion block 501 inside the upper mold 2 will be squeezed by the inner wall of the lower mold 3, sliding into the movable groove 2002 of the upper mold 2, and causing the second inclined surface 50101 to squeeze the first inclined surface 40101 of the extrusion ring 401, such as... Figure 10 As shown, this causes the extrusion ring 401 to move downward as a whole, and drives the spring telescopic rod 502 to extend downward. When the upper mold 2 separates from the lower mold 3, the extrusion ring 401 is no longer squeezed by the extrusion block 501, and returns to its initial state through the rebound force of the spring telescopic rod 502. This clamps and fixes the edge of the gel pillow located between the extrusion ring 401 and the lower surface of the upper mold 2, thereby improving the adsorption effect of the movable rod 4 on the gel pillow and further improving the demolding efficiency of the gel pillow.

[0059] When the extrusion block 501 inside the upper mold 2 is squeezed by the inner wall of the lower mold 3 and slides into the movable groove 2002 of the upper mold 2, the extrusion ring 401 gradually moves downward until the extrusion block 501 is completely inside the movable groove 2002. At this point, the extrusion ring 401 can no longer move downward. At the same time, the upper mold 2 is not completely in contact with the lower mold 3. As the upper mold 2 continues to move downward and in contact with the lower mold 3, the rubber ring 601 on the upper mold 2 gradually contacts the edge of the limiting groove 3001 of the lower mold 3 and rests against the limiting groove 3001. The isolation layer 5001 is squeezed, causing part of the isolation layer 5001 to move downward along with the rubber ring 601. When the extrusion ring 401 squeezes the isolation layer 5001 into the limiting groove 3001, the isolation layer 5001 between the rubber ring 601 and the lower surface of the extrusion ring 401 is in a relaxed state. This prevents the isolation layer 5001 from being directly squeezed and broken by the extrusion ring 401 in a taut state. Otherwise, during the gel pillow foaming process, some raw materials will pass through the broken part of the isolation layer 5001 and directly contact the lower mold 3, affecting the subsequent demolding effect of the gel pillow.

[0060] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
