Abstract

The utility model discloses a positive and negative pressure molding embossing device. The device adopts the main structure that a vacuum device is arranged on an upper shaft of a frame; a press roll group is installed on one side of the frame; the press roll group comprises three rolls and a belt; and the press roll group can perform lateral displacement and pressing motion. When the device presses heated raw material, the device can ensure that the raw material and an embossing roll are closer for molding by adopting positive pressure applied by the press roll group and negative pressure formed by the vacuum device, so as to achieve a better embossing effect.

Description

Positive/negative-pressure moulding embossing device

Technical field

The utility model relates to a kind of positive/negative-pressure moulding embossing device, malleation and the formed negative pressure of negative pressure device of utilizing the pressurization wheels to apply when espespecially behind heating raw materials, suppressing, and because raw material itself is gas permeable material, can make the positive/negative-pressure moulding embossing device of more tight moulding between raw material and the embossed wheel.

Background technology

Applicant's disclosed embossing device in No. 95115355 " vacuum forming machine embossing device " patent of invention case of TaiWan, China number of patent application is that connecting shaft is established a cylinder above the triangle support body at board, the sheathed leather sheath of this circumferential cylinder surface, and be coated on circumferential cylinder surface with ringle, then overlap outside the ringle and cover air permeable embossing wheel, in the time of above thermoplastic raw material is carried the board of passing through in advance, outside air is imported into cylinder, support ringle and make leather sheath heave, the confined space that then the corresponding bonding jumper of ringle is formed vacuumizes, and can form to the raw material that passes through suction, make softening raw material toward air permeable embossing wheel against, use at raw material and produce pressing result, utilize air permeable embossing wheel raw material to be formed the air permeable effect of negative pressure and the air permeable embossing wheel of arranging in pairs or groups, and can prevent that raw material from producing bubble in pressing process or the damage situation occurs, to reach best embossing effect, but, affect quality and the function of embossing because of the gas leakage that negative pressure causes and skin breakage, this disappearance is demanded urgently improving.

Summary of the invention

The utility model main purpose, be that a kind of positive/negative-pressure moulding embossing device is being provided, when suppressing, it can utilize the positive and negative pressure to raw material behind heating raw materials, and because raw material itself is gas permeable material, can make more closely moulding between raw material and the embossed wheel, to reach best embossing effect.

For reaching above-mentioned purpose, the utility model positive/negative-pressure moulding embossing device, mainly be to establish a negative pressure device in the support upper shaft, this support one side is provided with the pressurization wheels, and these pressurization wheels are done freely left and right displacement and the action of exerting pressure at support, when behind the heating raw materials of PVC or PU material, suppressing, can utilize press roll that the raw material that is transferred in mobile is exerted pressure, allow more tight moulding between raw material and the embossed wheel.

These pressurization wheels are comprised of three rollers and belt.

Compared with prior art, the beneficial effect that the utility model has is: malleation and the formed negative pressure of negative pressure device of utilizing the pressurization wheels to apply when the utility model is suppressed behind heating raw materials, and because raw material itself is gas permeable material, can make more closely moulding between raw material and the embossed wheel, to reach best embossing effect.

The specific embodiment

About technology contents, characteristics and the effect that reaches described in the utility model, in the middle of following cooperation describes in detail with reference to graphic preferred embodiment, can clearly present.Before being described in detail, this case needs to specify, its appended graphic basic structure of only explaining in a schematic way this case, therefore in these are graphic, only show structure or the assembly relevant with this case, and shown structure form, size, ratio, or component count etc., for a kind of optionally design, close first and state clearly.

At first see also Fig. 1, the utility model is applied for the TaiWan, China number of patent application for the applicant, and No. 95115355 " vacuum forming machine embossing device " patent of invention case improved, therefore in following explanation, only be illustrated with regard to improvement place, and namely repeat no more with regard to the structure of this vacuum forming machine embossing device, as shown in the figure, the utility model positive/negative-pressure forming machine embossing device mainly is to establish a negative pressure device 2 in support 1 upper shaft, and at a side of support 1 installing one pressurization wheels 3, wherein, pressurization wheels 3 are comprised of three rollers and belt, and these pressurization wheels 3 can be done a left side, right lateral displacement and compression motion.

See also Fig. 2 and shown in Figure 3, the utility model positive/negative-pressure forming machine embossing device is when undressed, also contactless between pressurization wheels 3 and the negative pressure device 2, when embossing device begins to add man-hour, at first, the raw material 4 of PVC or PU material can be heated to via heater 5 makes its material softening more than 100 ℃, raw material 4 after will softening again is sent to negative pressure device 2, when raw material 4 will pass through negative pressure device 2, pressurization wheels 3 can come raw material 4 is carried out the embossing action do displacement toward negative pressure device 2, allow raw material 4 can obtain simultaneously the double effects of malleation and negative pressure.

Can send via guide wheel 6 through the raw material 4 after the positive and negative pressure processing, this moment, the temperature of raw material 4 itself was still quite high, so must be collected after the cooling via a cooling guide wheel group 7 more again.

It is worth mentioning that, because embossing wheels 3 are larger, relative with the contact area of negative pressure device 2, the embossing area of raw material 4 just improves, and so, not only can reduce man-hour, and can obtain higher quality.

As can be known, this case really has significant progressive compared to general known embossing device from the above and accompanying drawing illustrated embodiment, and the technological means of its utilization really forms for this case designer research and development, succeeding this case and really met patent requirement, files an application in the whence in accordance with the law, and prays and grant patent for praying.In addition, this case disclosed above structure is to be the utility model preferred embodiment, and the equivalence of such as doing according to this case utility model structure changes, and must contain to be placed in the utility model protection domain.
