Description

Technical Field

[0001] The present application relates to the technical field of hose production, and in particular to a hose anti-pulling device. Background Art

[0002] Hose packaging is light in weight and easy to use. It is not only used in food packaging, but also in the packaging of daily necessities such as cosmetics, toothpaste, and shoe polish.

[0003] In the prior art, the structure of the hose mostly includes a hose body and a hose head, and the hose head is installed on one end of the hose body. During the hose molding process, the hose body is first molded, and then a mold is used to extrude and adhere to form the hose head, thereby completing the overall hose structure.

[0004] Regarding the above-mentioned related technologies, during the molding process of the hose head, the hose body is vertically arranged. When the mold is separated from the hose head, there is still a certain stickiness between the hose head and the mold, which causes the hose body to be easily lifted up by the mold and become loose. Therefore, there is room for improvement. Utility Model Content

[0005] In order to reduce the loosening of the hose body during the hose head molding process, the present application provides a hose anti-pulling device.

[0006] The present application provides a hose anti-pulling device that adopts the following technical solution:

[0007] A hose anti-pulling device comprises a support seat, a positioning rod, a pressure block and a driving member, wherein the positioning rod is connected to the support seat, and the positioning rod is used to position the hose body; the pressure block is located on one side of the positioning rod and is movably arranged on the support seat, and the pressure block is used to be pressed on the hose body; the driving member is arranged on the support seat and connected to the pressure block, and the driving member is used to control the pressure block to move in a direction close to the positioning rod.

[0008] By adopting the above technical solution, during production, the hose body is sleeved on the positioning rod; then the driving member is used to control the pressing block to move in the direction close to the positioning rod, so that the pressing block is pressed on the hose body to limit the position of the hose body. Then the hose head is formed. After the hose head is formed, during the demolding process, the hose body is subjected to the pressing force of the pressing block and is not easily lifted by the mold, thereby reducing the loosening of the hose body.

[0009] Preferably, the pressing block is made of elastic material.

[0010] By adopting the above technical solution, when the pressing block is pressed against the surface of the hose body, the pressing block will be elastically deformed by the reaction force, playing a buffering role, thereby reducing the damage of the pressing block to the hose body.

[0011] Preferably, the driving member is an air cylinder or an oil cylinder, and a piston rod of the air cylinder or the oil cylinder is connected to the pressing block.

[0012] By adopting the above technical solution, when the piston rod extends, the pressure block is controlled to move in a direction close to the positioning rod to achieve compression of the hose body; when the piston rod contracts, the pressure block is controlled to move in a direction away from the positioning rod to remove the external force on the hose body.

[0013] Preferably, an air outlet is provided at the top end of the positioning rod, and the air outlet is connected to an external air pump.

[0014] By adopting the above technical solution, the air outlet is connected to an external air pump so that gas will be sprayed at the air outlet. This can, on the one hand, reduce the local temperature of the positioning rod so that the hose body will not adhere to the positioning rod; on the other hand, it can drive the hose to shake, making it easier to remove the hose body from bottom to top.

[0015] Preferably, the support seat is lifted and lowered on the positioning rod.

[0016] By adopting the above technical solution, when it is necessary to limit the hose bodies of different lengths, the position of the support seat relative to the positioning rod can be adjusted. During the movement of the support seat, the driving member and the pressing block can be driven to move together, so that the pressing block can better press the hose body at the appropriate position, thereby improving applicability.

[0017] Preferably, the support seat is provided with a through hole for the positioning rod to pass through; a notch is provided at an edge of the support seat, the notch is connected to the through hole, and the support seat is locked to the positioning rod by a fastener.

[0018] By adopting the above technical solution, the through hole is used for the positioning rod to pass through, so that the support seat is sleeved on the positioning rod. When the position of the support seat needs to be adjusted, the fastener can be loosened first, and then the support seat can be controlled to move along the positioning rod; after the position is adjusted, the fastener can be tightened again to fix the support seat.

[0019] Preferably, the outer surface of the positioning rod is provided with scale lines, and the scale lines are arranged along the length direction of the positioning rod.

[0020] By adopting the above technical solution, the scale lines can be read by the staff, so as to roughly control the position to which the support seat should be adjusted according to the length of the hose body.

[0021] Preferably, the outer surface of the positioning rod is provided with an anti-stick coating.

[0022] By adopting the above technical solution, the anti-stick coating can increase the anti-stick performance of the surface of the positioning rod, thereby reducing the possibility of the hose body and the positioning rod adhering to each other.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] (1) By setting a positioning rod, a pressing block and a driving member, during production, the hose body is sleeved on the positioning rod; then the driving member is used to control the pressing block to move in the direction close to the positioning rod, so that the pressing block is pressed tightly on the hose body to limit the position of the hose body. After the hose head is formed, during the demolding process, the hose body will be subjected to the pressure of the pressing block and will not be easily lifted by the mold, thereby reducing the loosening of the hose body.

[0025] (2) By setting the scale lines, the scale lines can be read by production personnel to better adjust the position of the support seat relative to the positioning rod.

[0026] (3) By providing an anti-stick coating, the anti-stick coating can reduce the possibility of the hose body and the positioning rod adhering to each other. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples shown in the present application.

[0037] The present application embodiment discloses a hose anti-pulling device. Figure 2 and Figure 3 The anti-pulling device includes a base 1, a support seat 2 and a positioning rod 3. The base 1 serves as a supporting plane for installing the support seat 2 and the positioning rod 3. The positioning rod 3 is arranged in the vertical direction and one end is fixedly connected to the base 1. The positioning rod 3 is used to position the hose body. The support seat 2 is installed on the positioning rod 3, and a pressure block 10 and a driving member 9 are respectively installed on the support seat 2; the pressure block 10 is located on one side of the positioning rod 3 and is movably arranged on the support seat 2 in the horizontal direction. The pressure block 10 is used to press the hose body mounted on the positioning rod 3.

[0038] The driving member 9 is mounted on the support seat 2 and connected to the pressing block 10. The driving member 9 is used to control the pressing block 10 to move in a direction close to or away from the positioning rod 3. The driving member 9 is a cylinder or an oil cylinder. In this embodiment, the cylinder is taken as an example, and the piston rod of the cylinder is fixedly connected to the pressing block 10. When the piston rod is extended, the pressing block 10 is controlled to move in a direction close to the positioning rod 3 to achieve compression of the hose body; when the piston rod is contracted, the pressing block 10 is controlled to move in a direction away from the positioning rod 3 to remove the external force on the hose body.

[0039] Combination Figure 4 During production, the hose body is sleeved on the positioning rod 3; then the cylinder is used to control the pressing block 10 to move in the direction close to the positioning rod 3, so that the pressing block 10 is pressed against the hose body to limit the position of the hose body. Then the hose head is formed. After the hose head is formed, during the demolding process, the hose body is subjected to the pressing force of the pressing block 10 and is not easily lifted by the mold, thereby reducing the loosening of the hose body.

[0040] Among them, the positioning rod 3 is made of metal material and the outer surface is coated with an anti-stick coating. The anti-stick coating prevents adhesion by changing the physical and chemical properties of the metal surface, thereby increasing the anti-stick performance of the surface of the positioning rod 3, thereby reducing the possibility of the hose body and the positioning rod 3 adhering to each other.

[0041] The pressing block 10 is made of elastic material, so that the pressing block 10 has the ability of elastic deformation. The elastic material includes but is not limited to urethane foam, silicone or rubber, and silicone is used in this embodiment. When the pressing block 10 is pressed tightly on the surface of the hose body, the pressing block 10 will be elastically deformed by the reaction force, which plays a role of buffering and protection, thereby reducing the damage of the pressing block 10 to the hose body.

[0042] In addition, an air outlet 4 is provided at the top of the positioning rod 3, and the air outlet 4 is connected to an external air pump so that gas can be ejected from the air outlet 4. After the hose body is sleeved on the positioning rod 3, the air outlet 4 is located inside the hose body. During the molding process of the hose head, the gas ejected from the air outlet 4 can reduce the local temperature of the positioning rod 3 so that the hose body will not adhere to the positioning rod 3; secondly, the blowing force can drive the hose to shake, making it easier to remove the hose body from bottom to top.

[0043] According to some embodiments of the present application, optionally, please refer to Figure 2The support seat 2 is block-shaped and is lifted and lowered on the positioning rod 3. The support seat 2 can move up and down along the length direction of the positioning rod 3. Specifically, a through hole 5 is provided on the support seat 2, and the through hole 5 is used for the positioning rod 3 to pass through; a notch 6 is also provided at the edge of the support seat 2, and the notch 6 is connected to the through hole 5. The support seat 2 is locked on the positioning rod 3 by a fastener 7. The fastener 7 is a fastening bolt or a fastening screw. In this embodiment, it is a fastening bolt. The two ends of the fastening bolt are respectively located on both sides of the notch 6. The fastening bolt is locked at the position where the notch 6 is located, so that the support seat 2 is fixed to the positioning rod 3.

[0044] When it is necessary to limit the hose bodies of different lengths, the position of the support seat 2 relative to the positioning rod 3 can be adjusted. During the movement of the support seat 2, the driving member 9 and the pressing block 10 can be moved together so that the pressing block 10 can better press the hose body at the appropriate position to improve applicability.

[0045] Among them, the outer surface of the positioning rod 3 is also provided with scale lines 8, which are arranged along the length direction of the positioning rod 3. The scale lines 8 can be read by the staff, so as to roughly control the position to which the support seat 2 should be adjusted according to the length of the hose body.

[0046] The implementation principle of the hose anti-lifting device of the embodiment of the present application is as follows: during production, the hose body is sleeved on the positioning rod 3; then the cylinder is used to control the pressing block 10 to move in the direction close to the positioning rod 3, so that the pressing block 10 is pressed tightly on the hose body to limit the position of the hose body. After the hose head is formed, during the demolding process, the hose body will be subjected to the pressure of the pressing block 10 and will not be easily lifted by the mold, thereby reducing the loosening of the hose body.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
