Description

Technical Field

[0001] The utility model relates to the technical field of paper bottle production, in particular to a pressure storage type elastic bag body control mechanism. Background Art

[0002] With the development of technology, more and more plastic products are replaced by paper products, including the use of paper-plastic bottles instead of plastic bottles. The existing process of paper-plastic bottle products is to prepare two halves of the bottle and then bond them with an adhesive (such as patent CN201320746431). However, due to the processing technology at the junction of the two halves of the bottle, the aesthetics of this paper-plastic bottle is poor. For this reason, the applicant has developed a paper bottle production equipment that can integrally form paper-plastic bottles, which includes a paper bottle wet blank forming device and a paper bottle hot pressing shaping device, wherein the paper bottle hot pressing shaping device is provided with two hot pressing molds and a pressure storage elastic bag control mechanism The pressure-accumulating elastic bag control mechanism is used to extend into the opening of the hot-pressing mold when two hot-pressing molds are combined to prepare a paper mold, and to squeeze out the moisture on the paper mold by injecting fluid into the elastic bag body (internal high-pressure forming is a kind of air pressure or hydraulic forming technology. It applies high-pressure gas or liquid to the inside of the blank so that the product fits tightly with the inner wall of the mold cavity, making the inner and outer wall surfaces of the blank smooth and the wall thickness uniform). The applicant has developed a paper bottle hot-pressing shaping device that uses a hot-pressing upper mold and a hot-pressing lower mold arranged up and down to perform hot-pressing shaping on the wet paper bottle blank, and therefore a corresponding pressure-accumulating elastic bag control mechanism is set for it. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a pressure storage elastic bag control mechanism, which utilizes the inner cavity side wall of the tube body to buffer the fluid.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The pressure-accumulating elastic bag control mechanism comprises a bracket, a pipe component, an elastic bag body, a displacement driving device and a pump body. The pipe component is arranged to slide horizontally or obliquely upward relative to the bracket. The pipe component is provided with a hollow pipe body, and a plurality of through holes are provided at the end of the pipe body. The elastic bag body is sleeved on the outside of the pipe body and covers the through holes. The open end of the elastic bag body is sealed and fixed relative to the pipe body. The displacement driving device is used to drive the pipe component to move toward the outer end of the bracket so that the end of the pipe body provided with the through holes is located outside the edge of the end of the bracket. The pump body is used to input fluid into the pipe body or extract fluid from the pipe body.

[0006] Compared with the prior art, the pressure-accumulating elastic bag control mechanism of the utility model has the following beneficial effects:

[0007] (1) The utility model has a tube member slidably arranged on a bracket, and the tube member is driven by a displacement driving device to move toward the outer end of the bracket, so that one end of the tube body provided with a through hole is located outside the front end edge of the bracket to be inserted into the mold (after the hot pressing upper mold and the hot pressing lower mold are closed), wherein the tube member includes a hollow tube body with a plurality of through holes at the end, and the elastic bag body is sleeved on the outer side of the tube body and covers the through holes. When the pump body fills the elastic bag body with fluid, the fluid contacts the inner cavity of the tube body and flows along the side wall of the inner cavity of the tube body to the through holes and then flows into the elastic bag body. The expansion of the elastic bag body applies high pressure to the inside of the blank so that the blank and the inner wall of the mold cavity fit tightly;

[0008] (2) The elastic bag of the utility model contains high-pressure gas or liquid. The utility model controls the pressure increase, pressure storage, and pressure release through the pump body, so that the elastic bag can switch between the natural state and the expanded state, and the elastic bag can be deformed from the contracted state to the corresponding shape required by the process, so that the elastic bag can freely enter and exit the interior of the paper molded product;

[0009] (3) The utility model can quickly, continuously and cyclically switch the elastic bag body between the natural state and the expanded state, thereby improving production efficiency.

[0013] The above arrangement allows the open end of the elastic bag body to be easily mounted on the end of the tube body with the through hole, and also enables the mounting ring to fit tightly with the expanded portion of the tube body, thereby firmly clamping the elastic bag body to prevent the elastic bag body from loosening.

[0014] Furthermore, a sealing member is provided between the mounting ring and the tube body; and / or a sealing portion folded inwards is provided at the opening end of the elastic bag body.

[0015] The sealing part on the sealing element and the elastic bag body can improve the sealing performance between the tube body, the mounting ring and the elastic bag body, and prevent the fluid from flowing out from the gap between the tube body, the mounting ring and the elastic bag body.

[0016] Furthermore, the diameter of the through hole located on the inner wall of the tube body is smaller than the diameter of the through hole located on the outer wall of the tube body.

[0017] The above-mentioned arrangement makes the through hole trumpet-shaped, so that the fluid flows out of the through hole radially. On the one hand, it avoids the concentrated outflow of the fluid to produce a large impact. On the other hand, it can make the expansion speed of the elastic bag body uniform, ensure that different areas of the paper bottle wet blank are subjected to uniform force, and improve the drying effect of the elastic bag body on the paper bottle wet blank.

[0018] Furthermore, it also includes a slide seat and a slide rail, the slide rail is arranged on the bracket, the slide seat is slidably connected to the slide rail, and the pipe component is fixed on the slide seat.

[0020] Furthermore, a clamp is fixedly provided on the slide seat, and the clamp is fixedly connected to the pipe member.

[0021] By arranging a clamp to fix the pipe component on the slide, it is convenient for production personnel to install the pipe component on the slide or remove the pipe component from the slide by installing / and removing the clamp.

[0022] Furthermore, the clamp includes an upper clamping member, a lower clamping member and a fastener, the lower clamping member is fixedly connected to the slide seat, and the upper clamping member is detachably arranged on the upper end of the lower clamping member through the fastener, and the upper notch and the lower notch that match the outer surface of the pipe component are respectively provided on the opposite surfaces of the upper clamping member and the lower clamping member, and the upper notch and the lower notch are enclosed to clamp the pipe component.

[0023] The clamp adopts a split design, which consists of three parts: an upper clamping piece, a lower clamping piece and a fastener, so it is easy to disassemble and reduce the difficulty of production personnel to install and remove the pipe components.

[0024] Furthermore, it also includes a pipe member fixing mechanism; the pipe member fixing mechanism includes a fixing piece and a positioning piece arranged on the bracket, the positioning piece is arranged to keep a distance from the sliding seat when the end of the pipe member provided with a through hole moves beyond the edge of the bracket; when the end of the pipe member provided with a through hole moves beyond the edge of the bracket, the positioning piece and the sliding seat are connected by the fixing piece to limit the movement range of the sliding seat.

[0025] Furthermore, it also includes a pipe member fixing mechanism; the pipe member fixing mechanism includes a fixing piece and a positioning piece arranged on the bracket, the positioning piece is arranged to keep a distance from the slide seat when the end of the pipe member provided with a through hole moves beyond the edge of the bracket; when the end of the pipe member provided with a through hole moves beyond the edge of the bracket, the positioning piece and the clamp are connected by the fixing piece to limit the movement range of the slide seat.
