Description

Technical Field

[0001] The utility model relates to the technical field of demoulding equipment, and specifically, to an air-blowing demoulding device for glove demoulding. Background Art

[0002] Disposable gloves are gloves made of rubber sheets or films, and are mainly used in industries with high hygiene requirements such as medical treatment, laboratories, and food processing to avoid cross-infection and save replacement costs.

[0003] After the gloves are baked and formed on the hand mold, the demoulding machine will separate the gloves from the hand mold. However, in case of abnormal separation, all or part of the gloves remain on the hand mold. The gloves baked with the hand mold with residual gloves are all defective products and need to be cleaned in time. The existing form of separating the residual gloves from the hand mold is usually manual separation. This separation method is not only time-consuming and laborious, but also the temperature in the production workshop is relatively high, and workers are prone to heat stroke after working for a long time.

[0004] Therefore, there is an urgent need for a new device for separating gloves from the hand mold. Summary of the Utility Model

[0005] The utility model provides an air-blowing demoulding device for glove demoulding, which solves the problem of low glove production efficiency caused by manual separation of gloves from the hand mold in the prior art.

[0006] The technical solution of the utility model is as follows: An air-blowing demoulding device for glove demoulding, comprising:

[0007] A frame;

[0008] A transmission frame, located above the frame, with a hand mold arranged on the transmission frame, and a glove sleeved on the hand mold;

[0009] An air-blowing mechanism, arranged on the frame and used to blow the glove off the hand mold;

[0010] Wherein, the air-blowing mechanism includes a first reverse blowing air pipe, a first forward blowing assembly, a second reverse blowing air pipe, and a second forward blowing assembly arranged in sequence; the first reverse blowing air pipe and the second reverse blowing air pipe are located below the hand mold, and the first forward blowing assembly and the second forward blowing assembly are located above the hand mold;

[0011] Both the first forward blowing assembly and the second forward blowing assembly include a plurality of forward blowing air pipes, and the air outlets of the first reverse blowing air pipe, the second reverse blowing air pipe, and all the forward blowing air pipes are flat and all face the hand mold.

[0012] As a further technical solution, the lengths of the forward blowing air pipes in the first forward blowing assembly from the hand mold fingertips decrease in sequence, and the length of the air outlet of the forward blowing air pipe close to the first reverse blowing air pipe from the hand mold fingertips is the largest.

[0013] As a further technical solution, the angle between the axis of the positive blowing pipe in the first positive blowing assembly and the axis of the hand mold gradually decreases, and the angle between the axis of the positive blowing pipe near the first negative blowing pipe and the axis of the hand mold is the largest.

[0014] As a further technical solution, the lengths from the air outlets of the positive blowing pipes in the second positive blowing assembly to the fingertips of the hand mold gradually decrease, and the length from the air outlet of the positive blowing pipe near the second negative blowing pipe to the fingertips of the hand mold is the largest.

[0015] As a further technical solution, the angle between the axis of the positive blowing pipe in the second positive blowing assembly and the axis of the hand mold gradually increases, and the angle between the axis of the positive blowing pipe near the second negative blowing pipe and the axis of the hand mold is the smallest.

[0016] As a further technical solution, blowing mechanisms are arranged on both sides of the hand mold.

[0017] As a further technical solution, the blowing mechanisms located on both sides of the hand mold are symmetrically arranged with the hand mold as the center.

[0018] As a further technical solution, the blowing mechanism further includes an air valve assembly arranged on the frame, and the air valve assembly is respectively connected to the first negative blowing pipe, the first positive blowing assembly, the second negative blowing pipe, and the second positive blowing assembly through air pipes.

[0019] As a further technical solution, hand molds are arranged on both sides of the transmission frame, and blowing mechanisms are arranged on both sides of the hand molds.

[0020] As a further technical solution, the hand molds located on both sides of the transmission frame are symmetrically arranged with the transmission frame as the center.

[0021] The working principle and beneficial effects of the present utility model are as follows: The air-blowing demolding device for glove demolding includes a frame, a transmission frame, and a blowing mechanism. Among them, the transmission frame is located above the frame, and a hand mold is arranged on the transmission frame, and a glove is sleeved on the hand mold. The blowing mechanism is arranged on the frame, and the blowing mechanism includes a first reverse blowing air pipe, a first positive blowing component, a second reverse blowing air pipe, and a second positive blowing component arranged in sequence. Among them, the first reverse blowing air pipe and the second reverse blowing air pipe are arranged side by side, and both the first reverse blowing air pipe and the second reverse blowing air pipe blow air along the direction where the glove does not separate from the hand mold. They are mainly used to enable the gas blown out by the first positive blowing component and the second positive blowing component to enter between the gloves, thereby realizing the detachment of the gloves from the hand mold. Both the first positive blowing component and the second positive blowing component can blow gas into the gloves, and the gas enters the gap between the gloves and the hand mold. As more and more gas enters, the separation of the gloves from the hand mold can ultimately be achieved, and another manifestation is that the gloves fall off the hand mold. The first positive blowing component is located between the first reverse blowing air pipe and the second reverse blowing air pipe, and the second reverse blowing air pipe is located between the first positive blowing component and the second positive blowing component. Through two times of reverse blowing and positive blowing, the gloves can be quickly detached from the hand mold. In addition, the air outlets of the first reverse blowing air pipe, the second reverse blowing air pipe, and all the positive blowing air pipes are set to be flat and all face the hand mold, so that the gas is more conducive to blowing onto the surface of the gloves and the gap between the gloves and the hand mold.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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 fall within the scope of protection of the present invention.

[0034] Embodiment 1

[0035] As Figures 1 to 7 shown, this embodiment proposes a pneumatic blowing demolding device for glove demolding, including:

[0036] Frame 1;

[0037] Transmission frame 2, located above the frame 1, with a hand mold arranged on the transmission frame 2, and a glove sleeved on the hand mold;

[0038] Blowing mechanism 3, arranged on the frame 1 and used to blow the glove off the hand mold;

[0039] Among them, the blowing mechanism 3 includes a first reverse blowing pipe 31, a first forward blowing assembly 32, a second reverse blowing pipe 33 and a second forward blowing assembly 34 arranged in sequence; the first reverse blowing pipe 31 and the second reverse blowing pipe 33 are located below the hand mold, and the first forward blowing assembly 32 and the second forward blowing assembly 34 are located above the hand mold;

[0040] Both the first forward blowing assembly 32 and the second forward blowing assembly 34 include a plurality of forward blowing pipes 36, and the air outlets of the first reverse blowing pipe 31, the second reverse blowing pipe 33 and all the forward blowing pipes 36 are flat and all face the hand mold.

[0041] In this embodiment, the pneumatic blowing demolding device for glove demolding includes a frame 1, a transmission frame 2 and a blowing mechanism 3. Among them, the transmission frame 2 is located above the frame 1, with a hand mold arranged on the transmission frame 2, and a glove sleeved on the hand mold.

[0042] The air blowing mechanism 3 is arranged on the frame 1. The air blowing mechanism 3 includes a first reverse air blowing pipe 31, a first forward air blowing assembly 32, a second reverse air blowing pipe 33, and a second forward air blowing assembly 34 arranged in sequence. Among them, the first reverse air blowing pipe 31 and the second reverse air blowing pipe 33 are arranged side by side, and both the first reverse air blowing pipe 31 and the second reverse air blowing pipe 33 blow air along the direction in which the glove does not detach from the hand mold. They are mainly to enable the air blown out by the first forward air blowing assembly 32 and the second forward air blowing assembly 34 to enter between the gloves, thereby realizing the detachment of the gloves from the hand mold. Both the first forward air blowing assembly 32 and the second forward air blowing assembly 34 can blow air into the gloves. The air enters the gap between the glove and the hand mold. As more and more air enters, the separation of the glove from the hand mold can be finally realized, and another manifestation is that the glove falls off the hand mold. The first forward air blowing assembly 32 is located between the first reverse air blowing pipe 31 and the second reverse air blowing pipe 33, and the second reverse air blowing pipe 33 is located between the first forward air blowing assembly 32 and the second forward air blowing assembly 34. Through two times of reverse blowing and forward blowing, the glove can be quickly detached from the hand mold. In addition, the air outlets of the first reverse air blowing pipe 31, the second reverse air blowing pipe 33, and all the forward air blowing pipes 36 are set to be flat and all face the hand mold, so that the air is more conducive to blowing onto the surface of the glove and into the gap between the glove and the hand mold.

[0043] Embodiment 2

[0044] As Figures 5 to 7 shown, on the basis of Embodiment 1, in this embodiment, it is proposed that the lengths of the forward air blowing pipes 36 in the first forward air blowing assembly 32 from the fingertips of the hand mold gradually decrease, and the length of the air outlet of the forward air blowing pipe 36 close to the first reverse air blowing pipe 31 from the fingertips of the hand mold is the largest. The included angle between the axis of the forward air blowing pipe 36 in the first forward air blowing assembly 32 and the axis of the hand mold gradually decreases, and the included angle between the axis of the forward air blowing pipe 36 close to the first reverse air blowing pipe 31 and the axis of the hand mold is the largest. The lengths of the air outlets of the forward air blowing pipes 36 in the second forward air blowing assembly 34 from the fingertips of the hand mold gradually decrease, and the length of the air outlet of the forward air blowing pipe 36 close to the second reverse air blowing pipe 33 from the fingertips of the hand mold is the largest. The included angle between the axis of the forward air blowing pipe 36 in the second forward air blowing assembly 34 and the axis of the hand mold gradually increases, and the included angle between the axis of the forward air blowing pipe 36 close to the second reverse air blowing pipe 33 and the axis of the hand mold is the smallest.

[0045] In a practical application scenario, there are three positive blowing air pipes 36 inside the first positive blowing assembly 32. Among them, the three positive blowing air pipes are arranged at the same interval, and the interval is usually selected as 40 mm ± 2 mm; there are nine positive blowing air pipes 36 inside the second positive blowing assembly 34. Among them, the nine positive blowing air pipes are arranged at the same interval, and the interval is usually selected as 40 mm ± 2 mm; along the moving direction of the hand mold, the blowing ports of the three positive blowing air pipes 36 in the first positive blowing assembly 32 approach the hand mold in sequence, and the nine positive blowing air pipes 36 in the second positive blowing assembly 34 move away from the hand mold in sequence. This is because there is a first reverse blowing air pipe 31 in front of the first positive blowing assembly 32 and a second reverse blowing air pipe 33 in front of the second positive blowing assembly 34.

[0046] The gas blown by the first reverse blowing air pipe 31 towards the hand mold is to keep a better connection between the glove and the hand mold, and blow the glove straight, so as to prevent the movement between the glove and the hand mold from increasing the friction force between the glove and the hand mold, and further causing the first positive blowing assembly 32 to lose the effect of blowing and demolding. Similarly, the second reverse blowing air pipe 33 also has the same function. With the cooperation of the first reverse blowing air pipe 31 and the second reverse blowing air pipe 33, the glove can be normally detached from the hand mold.

[0047] Embodiment III

[0048] As Figures 1 to 3 shown, on the basis of Embodiment I or Embodiment II, this embodiment proposes that blowing mechanisms 3 are provided on both sides of the hand mold. The blowing mechanisms 3 located on both sides of the hand mold are arranged symmetrically with the hand mold as the center.

[0049] In this embodiment, in order to enable the glove to smoothly detach from the hand mold, blowing mechanisms 3 are provided on both sides of the hand mold, that is, for the same hand mold, at least one set of blowing mechanism 3 is included on each symmetric side.

[0050] In a practical application scenario, a set of blowing mechanism 3 is provided on each side of the same row of hand molds, and the respective blowing air pipes involved in the blowing mechanism 3 are completely symmetrically arranged. For example, the two first reverse blowing air pipes 31 arranged on the opposite sides of the hand mold have a completely symmetrical spatial layout, which is beneficial to making the blowing force received by the glove more uniform.

[0051] Furthermore, as Figures 1 to 3 shown, this embodiment proposes that the blowing mechanism 3 further includes a gas valve assembly 35 arranged on the frame 1. The gas valve assembly 35 is respectively connected to the first reverse blowing air pipe 31, the first positive blowing assembly 32, the second reverse blowing air pipe 33 and the second positive blowing assembly 34 through air pipes.

[0052] In this embodiment, in order to control the air pressure of the air blowing pipe in the air blowing mechanism 3, the air blowing mechanism 3 further includes a pneumatic valve assembly 35. The pneumatic valve assembly 35 can be in the form of a valve island or arranged in rows and columns with multiple pneumatic valves. The pneumatic valve assembly 35 is connected to the first reverse air blowing pipe 31, all the forward air blowing pipes 36 in the first forward air blowing assembly 32, the second reverse air blowing pipe 33, and all the forward air blowing pipes 36 in the second forward air blowing assembly 34 through air pipes respectively.

[0053] Further, as Figures 1 to 3 shown, in this embodiment, hand molds are provided on both sides of the transmission frame 2, and air blowing mechanisms 3 are provided on both sides of the hand molds. The hand molds located on both sides of the transmission frame 2 are symmetrically arranged with the transmission frame 2 as the center.

[0054] In this embodiment, in order to improve the production efficiency of gloves, for the transmission frame 2 on the same production line, two rows of hand molds can be provided on it, and the two rows of hand molds are symmetrically arranged. Compared with the structure of a single row of hand molds, the structure of two rows of hand molds can better improve the production efficiency of gloves. For any row of hand molds, there are two sets of air blowing mechanisms 3 corresponding to it, that is, when the whole production line includes two rows of hand molds, this production line will include four sets of air blowing mechanisms 3.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
