Description

Technical Field

[0001] This invention relates to the field of pickle production technology, and in particular to a rotational molding equipment and molding process for pickle production. Background Technology

[0002] Peakball is an indoor or outdoor racket / racket sport in which two players (singles) or four players (doubles) use solid rackets to hit a perforated, hollow polymer ball over a 36-inch (0.91-meter) high net. The production of peakballs typically involves an extruder, which melts and blends the raw materials to facilitate subsequent molding and processing. After use, the extruder body, the inner walls of the die, and the surface of the screw extruder all retain material.

[0003] Utility model patent CN222792612U discloses a rotational molding mold for producing pickles, including a fixed machine base. An injection molding frame is installed on the upper surface of the fixed machine base, and an injection molding barrel is installed on the injection molding frame. A first limiting plate and a second limiting plate are respectively installed on the upper surface of the fixed machine base. The first limiting plate and the second limiting plate are fixedly connected by positioning guide posts. A sealed injection cavity is sealed to a pickle mold cavity through a pipeline. A sealing joint is provided at the bottom end of the pickle mold cavity. The sealing joint is sealed to a vacuum pump located below the fixed machine base through a vacuum pipeline.

[0004] The document mentioned above uses a static peak ball mold cavity for peak ball production, which will result in uneven thickness of the produced peak balls. Summary of the Invention

[0005] This invention provides a rotational molding equipment and molding process for producing pickles, which solves the problem that the existing technology uses a static pickle mold cavity for pickle production, which leads to uneven thickness defects in the produced pickles.

[0006] On one hand, the present invention provides a rotational molding equipment for producing pickles, including a base, a hollow bracket is mounted on the top of the base, two guide rods are mounted inside the hollow bracket, a fixed plate is fixed in the middle of the two guide rods, a movable plate is slidably connected through the left side of the two guide rods, an electric telescopic rod is mounted on the side of the movable plate, and a rotational molding component is mounted on the fixed plate and the movable plate.

[0007] The rotational molding assembly includes a feeding pipe, a rotating shaft, and a small motor. The feeding pipe passes through and is fixed inside a fixed plate. An injection port is fitted to the top right side of the feeding pipe. An auger is rotatably connected to the right side of the feeding pipe. A first pick ball mold is fitted to the left side of the feeding pipe via a sealed rotary joint. A vacuum pump is fitted to the side of the fixed plate and is internally connected to the sealed rotary joint. The first rotating shaft passes through and is rotatably connected inside a movable plate. A second pick ball mold is fixed to the front end of the first rotating shaft, and a first gear is fixed to the middle of the first rotating shaft. The small motor is embedded in the movable plate, and a second gear, meshing with the first gear, is fixed to the output shaft of the small motor. This application achieves dynamic rotational molding by setting up the rotational molding assembly. First, an electric telescopic rod controls the second pick ball mold to fit with the first pick ball mold. Then, the small motor acts as a driving force, causing the fitted second and first pick ball molds to rotate, performing dynamic rotational molding. This ensures that the produced pick balls have a consistent thickness, solving the problem of inconsistent thickness in existing technologies.

[0008] On the other hand, the second pick ball mold is bolted to the first pick ball mold, and a rubber gasket is fitted at the joint between the first pick ball mold and the second pick ball mold.

[0009] On the other hand, the base has a feeding port in the middle for feeding pickles, and the side of the auger needs to be connected to the output shaft of the rotary motor.

[0010] On the other hand, the base is equipped with an auxiliary demolding component inside the discharge port to help the pickle ball demold quickly.

[0011] On the other hand, the auxiliary demolding assembly includes a hydraulic chamber, a support rod, and an arc-shaped toothed rod. The support rod is hinged inside the material outlet of the base. A rotating rod 2 is rotatably connected to the front end of the support rod. Rubber friction wheels are fixed on both sides of the rotating rod 2, and a gear 3 is fixed in the middle of the rotating rod 2. The hydraulic chamber is fixed inside the material outlet of the base. A hydraulic rod 1 is slidably connected to a piston at one end of the hydraulic chamber, and a hydraulic rod 2 is slidably connected to a piston at the other end of the hydraulic chamber. The arc-shaped toothed rod is connected to the base and meshes with the gear 3. A limit plate is fixed to the bottom of the hydraulic chamber, and the limit plate is connected to the support rod via an elastic telescopic rod. This application helps to quickly demold the pickle by setting an auxiliary demolding assembly. The rotation of the support rod drives the rubber friction wheels to rotate, which helps to demold the pickle stuck in the pickle mold 2 or pickle mold 1, achieving an automatic demolding effect and increasing the efficiency of the equipment.

[0012] On the other hand, the hydraulic rod two is rotatably connected to a roller on the side near the support rod, and the hydraulic rod one is fixedly connected to the side of the movable plate.

[0013] On the other hand, a vibration assembly is fitted to the outside of the injection port. The vibration assembly includes a shaped toothed rod, a small bracket, and an arc-shaped rod. The shaped toothed rod is fixed to the side of the movable plate, and the small bracket is fixed to the side of the fixed plate. A rotating rod three is rotatably connected through the interior of the small bracket. A actuating plate is fixed to the middle of the rotating rod three, and a gear four that meshes with the shaped toothed rod is fixed to the front end of the rotating rod three. The arc-shaped rod is hinged to the outside of the injection port, and a spring is fixed between the arc-shaped rod and the outside of the injection port. A metal roller is rotatably connected to one side of the arc-shaped rod, and an L-shaped plate is fixed to the other side of the arc-shaped rod. The L-shaped plate is located on the movement trajectory of the actuating plate. This application uses a vibration assembly to vibrate the injection port, which not only accelerates the material discharge speed from the injection port to the feeding pipe but also prevents raw materials from clogging the injection port, achieving this through small-scale vibration transmission.

[0014] A molding process for a rotational molding equipment used in the production of pickles includes the following steps:

[0015] Step 1: First, use the electric telescopic rod to move the movable plate, which in turn moves the second peakball mold until it fits against the first peakball mold. Then, start the vacuum pump to create a vacuum.

[0016] Step 2: Then connect an external rotary motor to the auger to make it rotate, and send the raw material in the injection port into the second and first peakball molds through the feeding pipe. Then, a small motor drives the second gear to rotate, which in turn drives the first gear to rotate, so that the second and first peakball molds rotate synchronously.

[0017] Step 3: After the rotational molding in Step 2 is completed, the peak ball is quickly demolded using an auxiliary demolding component.

[0018] The advantages of this application are:

[0019] (1) This application uses a rotational molding assembly to perform dynamic rotational molding. First, the second peak ball mold is controlled to fit together with the first peak ball mold by an electric telescopic rod. Then, a small motor is used as the driving force to make the second peak ball mold and the first peak ball mold rotate after they are fitted together, so as to perform dynamic rotational molding. This ensures that the produced peak balls have a consistent thickness and solves the problem of inconsistent thickness in the existing technology.

[0020] (2) This application helps the pickle to be demolded quickly by setting an auxiliary demolding component. The rotation of the support rod drives the rubber friction wheel to rotate, which helps the pickle stuck in the second pickle mold or the first pickle mold to be demolded. This can achieve the effect of automatic demolding and increase the efficiency of the equipment.

[0021] (3) This application uses a vibration component to vibrate the injection port, which can not only speed up the feeding speed of the injection port to the feeding pipe, but also prevent the raw material from being blocked in the injection port. This is achieved through small-scale vibration transmission. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] Example 1, see Figure 1-Figure 5 This embodiment provides a rotational molding equipment for producing pickles, including a base 100. A hollow bracket 200 is mounted on the top of the base 100. Two guide rods 300 are mounted inside the hollow bracket 200. A fixing plate 500 is fixed in the middle of the two guide rods 300. A movable plate 400 is slidably connected through the left side of the two guide rods 300. An electric telescopic rod 600 is mounted on the side of the movable plate 400. A rotational molding assembly 700 is mounted on the fixing plate 500 and the movable plate 400.

[0039] The rotational molding assembly 700 includes a feeding pipe 701, a rotating shaft 707, and a small motor 710. The feeding pipe 701 passes through and is fixed inside the fixed plate 500. An injection port 702 is fitted to the top right side of the feeding pipe 701. An auger 703 is rotatably connected to the right side of the inside of the feeding pipe 701. A first pickle mold 706 is fitted to the left side of the feeding pipe 701 via a sealed rotary joint 704. A vacuum pump 705 is fitted to the side of the fixed plate 500 and is internally connected to the sealed rotary joint 704. The rotating shaft 707 passes through and is rotatably connected inside the movable plate 400. A second pickle mold 708 is fixed to the front end of the rotating shaft 707. 8 is bolted to the first pickle mold 706, and a rubber gasket is fitted at the contact point between the first pickle mold 706 and the second pickle mold 708. Since the feeding pipe 701 is connected to the first pickle mold 706 through a sealed rotary joint 704, the sealing during vacuuming can be guaranteed without affecting the rotation of the first pickle mold 706. A gear 709 is fixed in the middle of the rotating shaft 707. A small motor 710 is embedded in the movable plate 400. A gear 711 that meshes with gear 709 is fixed at the output shaft of the small motor 710. A feeding port for feeding pickles is opened in the middle of the base 100. The side of the auger 703 needs to be connected to the output shaft of the rotary motor. By setting up a rotational molding assembly 700 for dynamic rotational molding, firstly, the electric telescopic rod 600 controls the second peak ball mold 708 to fit together with the first peak ball mold 706. Then, a small motor 710 is used as the driving force to make the fitted second peak ball mold 708 and the first peak ball mold 706 rotate, thus performing dynamic rotational molding. This ensures that the produced peak balls have a consistent thickness, solving the problem of inconsistent thickness in existing technologies.

[0040] In practical use, the above-mentioned equipment first moves the movable plate 400 by the electric telescopic rod 600. As the movable plate 400 moves, it pushes the second pickle mold 708 to the right under the action of the rotating shaft 707 until it fits against the first pickle mold 706. Then, the first pickle mold 706 and the second pickle mold 708 are connected by bolts to ensure their sealing. Then, the vacuum pump 705 is started to draw a vacuum. Next, the auger 703 is connected to an external rotary motor to make it rotate, and the raw material in the injection port 702 is fed through the feeding pipe 701. The material is fed into the second peak ball mold 708 and the first peak ball mold 706. Then, the small motor 710 is turned on to control the second gear 711 to rotate. The rotation of the second gear 711 drives the first gear 709 to rotate, so that the second peak ball mold 708 and the first peak ball mold 706 rotate synchronously to perform the rotational molding of the peak balls. However, since the feeding pipe 701 is connected to the first peak ball mold 706 through the sealed rotary joint 704, the sealing during vacuuming can be guaranteed without affecting the rotation of the first peak ball mold 706.

[0041] Example 2, see Figures 1-7 In this embodiment, based on Embodiment 1, an auxiliary demolding component 800 for quickly demolding the pickle is installed in the discharge port of the base 100. The auxiliary demolding component 800 includes a hydraulic chamber 801, a support rod 802, and an arc-shaped toothed rod 810. The support rod 802 is hinged in the discharge port of the base 100. A rotating rod 806 is rotatably connected to the front end of the support rod 802. Rubber friction wheels 807 are fixed on both sides of the rotating rod 806. A gear 808 is fixed in the middle of the rotating rod 806. The hydraulic chamber 801 is fixed to the base 100. Inside the feeding port of 00, a hydraulic cylinder 801 has a piston slidingly connected to a hydraulic rod 805 at one end, and a hydraulic rod 804 slidingly connected to a piston at the other end. An arc-shaped locking rod 810 is connected to the base 100 and meshes with a gear 808. A limit plate 803 is fixed to the bottom of the hydraulic cylinder 801, and the limit plate 803 is connected to the support rod 802 via an elastic telescopic rod 809. A roller is rotatably connected to the side of the hydraulic rod 804 near the support rod 802. The hydraulic rod 805 is fixedly connected to the side of the movable plate 400. An auxiliary demolding component 800 helps the pickles demold quickly. The rotation of the support rod 802 drives the rubber friction wheel 807 to rotate, helping to demold the pickles stuck in the pickle mold 708 or pickle mold 706. This achieves automatic demolding and increases the efficiency of the equipment.

[0042] In specific use, based on the first embodiment, as the movable plate 400 moves, it will squeeze the hydraulic rod 805. At this time, the liquid pressure in the hydraulic chamber 801 increases, causing the hydraulic rod 804 to extend, which in turn pushes the support rod 802 to rotate, randomly squeezing the elastic telescopic rod 809, and causing the two rubber friction wheels 807 to leave the movement trajectory of the second pick ball mold 708.

[0043] Meanwhile, after the rotational molding operation is completed, the movable plate 400 needs to be moved by the electric telescopic rod 600 to separate the second peak ball mold 708 from the first peak ball mold 706. During the separation process, as the movable plate 400 resets, it will pull the first hydraulic rod 805 to move. At this time, under the action of liquid pressure and the reset of the elastic telescopic rod 809, the support rod 802 will rotate. During the rotation, the third gear 808 on the rotating rod 806 will rotate under the action of the arc-shaped toothed rod 810. At this time, the rotating rod 806 will drive the rubber friction wheels 807 on both sides to rotate, and remove the finished peak balls stuck in the first peak ball mold 706 or the second peak ball mold 708. This can achieve the effect of automatic demolding and increase the efficiency of equipment use.

[0044] Example 3, see Figures 1-9In this embodiment, based on Embodiment 1, a vibration assembly 900 is assembled on the outside of the injection port 702. The vibration assembly 900 includes a special-shaped toothed rod 901, a small bracket 902, and an arc-shaped rod 903. The special-shaped toothed rod 901 is fixed to the side of the movable plate 400, and the small bracket 902 is fixed to the side of the fixed plate 500. A rotating rod 906 is rotatably connected through the inside of the small bracket 902. A toggle plate 907 is fixed in the middle of the rotating rod 906, and a gear 908 that meshes with the special-shaped toothed rod 901 is fixed at the front end of the rotating rod 906. The arc-shaped rod 903 is hinged to the outside of the injection port 702, and a spring is fixed between the arc-shaped rod 903 and the outside of the injection port 702. A metal roller 905 is rotatably connected to one side of the arc-shaped rod 903, and an L-shaped plate 904 is fixed to the other side of the arc-shaped rod 903. The L-shaped plate 904 is located on the movement trajectory of the toggle plate 907. By setting the vibration component 900 to vibrate the injection port 702, not only can the feeding speed of the injection port 702 to the feeding pipe 701 be accelerated, but the raw material can also be prevented from being blocked in the injection port 702. This is achieved through small-scale vibration transmission.

[0045] In practical use, based on Embodiment 1, as the movable plate 400 moves, it drives the shaped toothed rod 901 to move, which in turn drives the gear four 908 to rotate. The gear four 908 drives the rotating rod three 906 to rotate, which in turn drives the fixed actuating plate 907 to rotate. As the actuating plate 907 rotates, it strikes the L-shaped plate 904 on the side of the arc rod 903, causing the arc rod 903 to rotate. When the actuating plate 907 disengages from the L-shaped plate 904, the spring's rebound force causes the arc rod 903 to drive the metal roller 905 to quickly reset and strike the outside of the injection port 702. The resulting vibration not only accelerates the feeding speed of the injection port 702 to the feeding pipe 701, but also prevents the raw material from clogging inside the injection port 702.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
