With the development of polymer material science, more and more polymer material catheters with good biocompatibility are applied to interventional operations. However, due to the complexity of the anatomy, these medical tubing also need to be configured in different shapes depending on the anatomy. For example, in cardiac intervention type surgery, a doctor performs external operation under continuous projection of digital silhouettes, and the requirements on the shape and operability of the instrument are very high, and it is difficult for a medical tube of a conventional shape to satisfy the needs of the doctor. In the related art, because the medical tube made of the high polymer material has low melting point and is easy to mold, medical staff can heat and soften the medical tube in a heater or water bath heating mode and the like, and then bend the medical tube at a certain angle in a certain length through auxiliary tools. In the process, the operation is performed manually, so that the bending effect of the medical tubing obtained by manufacturing is easy to be insufficient, and meanwhile, the operation difficulty of medical staff is increased, and the postoperative effect of a patient is further affected.

Based on this, the present inventors devised a thermoforming apparatus in which a medical tubing 300 is placed in a mold 200 according to the shape of the cavity in the mold 200, and the mold 200 containing the medical tubing 300 is heated and cooled by the thermoforming apparatus. In this process, the medical tubing 300 is heated by the mold 200, is able to be softened to conform to the cavity within the mold 200, and is shaped upon cooling so that the medical tubing 300 has the shape of the cavity within the mold 200. Thus, the thermoforming device in the application can manufacture medical tubing 300 with different specifications, and the medical tubing 300 is better in manufacturing effect and higher in manufacturing precision.

FIG. 1 shows a schematic view of a thermoforming apparatus 100 from one perspective in an embodiment of the present application; FIG. 2 is a schematic diagram of an auxiliary feeding mechanism 130 according to an embodiment of the present disclosure; fig. 3 shows a top view of a mold 200 in an embodiment of the present application. For convenience of description, the drawings show only structures related to the embodiments of the present application.

In some embodiments, referring to fig. 1 and 2, embodiments of the present application provide a thermoforming apparatus 100, where the thermoforming apparatus 100 is provided with a feeding station a, a heating station b, and a cooling station c in sequence along a first direction F1. The thermoforming apparatus 100 includes a first conveyance mechanism 110, a heating mechanism 120, an auxiliary conveyance mechanism 130, a cooling mechanism 140, and a second conveyance mechanism 150. The first conveying mechanism 110 is disposed at the feeding station a, and the first conveying mechanism 110 is configured to convey the mold 200 for molding the medical tubing 300 in the first direction F1. The heating mechanism 120 is disposed at the heating station b, and is used for heating the mold 200 in a contact manner. The auxiliary conveying mechanism 130 includes a carrier 131 for transferring the mold 200, where the carrier 131 is configured to be capable of moving up and down along the second direction F2 to carry the mold 200, and the carrier 131 is further configured to be capable of moving back and forth along the first direction F1 between the feeding station a and the heating station b to cooperate with the first conveying mechanism 110 to transfer the mold 200 onto the heating mechanism 120. The cooling mechanism 140 is disposed at the cooling station c for cooling the mold 200. The second conveying mechanism 150 has a third conveying member 151, and the third conveying member 151 is used to circulate the mold 200 removed from the heating mechanism 120 to the cooling mechanism 140. Wherein the first direction F1 and the second direction F2 are perpendicular.

Alternatively, referring to fig. 1, when the mold 200 is placed on the first conveying member 111, the auxiliary conveying mechanism 130 moves up along the second direction F2 and carries the mold 200 with the carrier 131, the mold 200 placed on the first conveying mechanism 110 moves from the feeding station a to the heating mechanism 120 along the first direction F1 under the driving of the carrier 131 and completes the heating and molding, and the second conveying member 171 flows the mold 200 removed from the heating mechanism 120 to the cooling mechanism 140 to complete the cooling and molding. Thereby, the thermoforming process of the mold 200 is realized, so that the thermoforming process of the mold 200 is smoother, and the molding effect is better, and thus, the effect of the medical tubing 300 manufactured by the mold 200 is better.

The thermoforming apparatus 100 includes at least a first conveying mechanism 110, a heating mechanism 120, an auxiliary conveying mechanism 130, a cooling mechanism 140, and a second conveying mechanism 150. The first conveying mechanism 110 and the auxiliary conveying mechanism 130 are arranged to transfer the mold 200 for loading and heating, the heating mechanism 120 is arranged to heat and mold the mold 200, the second conveying mechanism 150 is arranged to transfer the heated mold 200 to the cooling mechanism 140, and the cooling mechanism 140 is arranged to finish cold molding and shaping of the mold 200. The thermoforming apparatus 100 described above improves the drawbacks of manually manufacturing the medical tubing 300, and has a better manufacturing effect, so that the quality of the medical tubing 300 manufactured by the mold 200 is higher.

In some embodiments, the first conveying mechanism 110 includes two first conveying members 111 spaced apart along the third direction F3, the heating mechanism 120 includes two heating members 121 spaced apart along the third direction F3, and the auxiliary conveying mechanism 130 is disposed between the two first conveying members 111 and between the two heating members 121. The carrier 131 is configured to be movable in the first direction F1 between the loading station a and the heating station b to transfer the mold 200 to the heating mechanism 120 in cooperation with the first conveying mechanism 110. The first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other.

As shown in fig. 1 and 2, the first conveying mechanism 110 has two first conveying members 111 spaced along the third direction F3, the mold 200 is placed on the first conveying members 111, the first conveying members 111 apply a vertical upward supporting force to the mold 200, and when the first conveying mechanism 110 is to transfer the mold 200, the auxiliary conveying mechanism 130 disposed between the two first conveying members 111 can provide a supporting force in the vertical direction, so that the first conveying members 111 and the auxiliary conveying mechanism 130 support the mold 200 together, and transfer the mold 200 between the two heating members 121 along the first direction F1 under the driving of the carrier 131, so as to complete the transportation of the mold 200 from the feeding station a to the heating station b.

Referring to fig. 2, the auxiliary feeding mechanism 130 has a first cylinder 132 reciprocally movable in a first direction F1 and a second cylinder 133 reciprocally movable in a second direction F2. The second cylinder 133 is connected to the carrier 131 and drives the carrier 131 to reciprocate in the second direction F2. The second cylinder 133 is fixedly connected to the first cylinder 132 at a side remote from the carrier 131, so that the first stage lever can reciprocate in the first direction F1 by means of the first cylinder 132.

Referring to fig. 3, it should be noted that, in the present application, the mold 200 to be molded has a larger volume and weight, and in some embodiments, the length h1 of the mold 200 is approximately 800 mm and the width h2 is approximately 600 mm, so that the load of the first conveying mechanism 110 and the auxiliary conveying mechanism 130 alone can be reduced by supporting the mold 200 together with the auxiliary conveying mechanism 130 and completing the transferring of the mold 200.

It can be understood that, if only the auxiliary feeding mechanism 130 is provided to transfer the mold 200, the auxiliary feeding mechanism 130 will not bear the huge gravity of the mold 200 itself, and since the contact area between the carrier 131 and the mold 200 is small, if only the carrier 131 carries the mold 200, the auxiliary feeding mechanism 130 will not be able to stably move. If only the first conveying mechanism 110 is provided to transfer the mold 200, when the mold 200 is moved to the next station, the friction force of the first conveying mechanism 110 against the mold 200 is insufficient, and the mold 200 may not be smoothly moved to the next station.

Therefore, the first conveying mechanism 110 and the auxiliary conveying mechanism 130 are arranged to move the mold 200 together, so that the mold 200 can be ensured to move stably in the transmission process, and the mold 200 can be smoothly conveyed to the heating station b, so that the forming process of the thermoforming device 100 on the mold 200 is smoother, and the forming effect of the mold 200 is improved.

Fig. 4 shows a schematic structural diagram of a lifting mechanism 160 according to an embodiment of the present application.

In some embodiments, the carrier 131 moves upward in the second direction F2 to have a material moving position, where the carrier 131 is located at the material moving position, and the carrier 131 is used to carry a carrying surface of the mold 200, and the carrying surface is flush with a conveying surface of the first conveying member 111 used to convey the mold 200.

The carrying surface of the carrier 131 for carrying the mold 200 refers to a portion where the carrier 131 directly contacts the mold 200, and the carrying surface of the first carrier 111 for carrying the mold 200 refers to a portion where the first carrier 111 directly contacts the mold 200.

Referring to fig. 1 to 4, when the mold 200 is on the first conveying mechanism 110, the carrier 131 can move upward along the second direction F2 until the mold 200 can be just carried, and the weight of the mold 200 is borne by the first conveying member 111 and the carrier 131 together, and the carrier 131 is at the material moving position. The bearing surface is flush with the conveying surface of the first conveying member 111 for conveying the mold 200, so that the pressure of the mold 200 can be uniformly distributed on the bearing surface of the bearing member 131 to the mold 200 and the conveying surface of the first conveying member 111 to the mold 200, the pressure of the bearing member 131 and the mold 200 borne by the first conveying member 111 is reduced, the moving load is reduced, and the moving process can be smoother and quicker.

In the embodiment shown in fig. 1, the first conveying member 111 is a roll, and it should be noted that the first conveying member 111 can be disposed on the first conveying mechanism 110 in an unpowered manner to support the mold 200 and enable the mold 200 to move more smoothly. The first conveying member 111 may also be disposed on the first conveying mechanism 110 at a certain initial speed, and it is understood that the initial speed is less than the speed at which the carrier 131 carries the mold 200 along the first direction F1, so as to avoid relative sliding between the first conveying member 111 and the mold 200 carried by the carrier 131, thereby causing sliding of the mold 200 and affecting the quality of the mold 200.

Referring to fig. 4, in some embodiments, the thermoforming apparatus 100 further comprises a lifting mechanism 160 disposed on the heating element 121. The jacking mechanism 160 is configured to be capable of reciprocating in the second direction F2, and the jacking mechanism 160 has an ejection position and a retraction position in the reciprocating motion. The jacking mechanism 160 is in the ejection position, and the bearing surface of the jacking mechanism 160 is flush with the bearing surface of the bearing member 131 located in the shifting position so as to support the die 200. The lifting mechanism 160 is in the retracted position, and the bearing surface of the lifting mechanism 160 is located below the bearing surface of the heating element 121 along the second direction F2, so as to place the mold 200 on the bearing surface of the heating element 121.

In connection with fig. 1 to 4, it should be noted that the height of the heating mechanism 120 in the second direction F2 is lower than the height of the mechanisms on both sides of the heating mechanism 120 in the second direction F2. The jacking mechanism 160 can complete heating of the mold 200 in cooperation with the heating mechanism 120, illustratively, the heating mechanism 120 is provided with a plurality of through holes 122 penetrating along the second direction F2, the jacking mechanism 160 is provided with a plurality of supporting rollers 161 matched with the through holes 122, the supporting rollers 161 are directly contacted with the mold 200 and support the mold 200, and the supporting rollers 161 can penetrate out of the through holes 122 and do lifting motion along the second direction F2.

When the auxiliary feeding mechanism 130 cooperates with the first conveying mechanism 110 to transfer the mold 200 to the heating station b, the lifting mechanism 160 is at the ejection position, and the carrier 131 moves the mold 200 onto the supporting roller 161 along the first direction F1, and at this time, the contact surface between the supporting roller 161 and the mold 200 is the carrying surface of the lifting mechanism 160. The bearing surface of the jacking mechanism 160 is flush with the bearing surface of the bearing member 131 at the shifting position, so that the process of moving the die 200 from the bearing member 131 to the supporting roller 161 can be smoother and safer.

After the mold 200 is completely transferred onto the supporting roller 161, the jacking mechanism 160 moves downward in the second direction F2, so that the supporting roller 161 is placed under the heating mechanism 120 via the through hole 122, and the carrier 131 is placed on the heating member 121 to be heated. At this time, the lifting mechanism 160 is in the retracted position.

The lifting mechanism 160 can be switched between the ejection position and the retraction position, so that the die 200 can be placed on the heating member 121 for heating after the heating member 121 is preheated, the heating mechanism 120 can heat the die 200 more uniformly, and the heating effect of the die 200 is improved.

In some embodiments, the thermoforming apparatus 100 is further provided with a joining station d located between the heating station b and the cooling station c along the first direction F1. The thermoforming apparatus 100 further comprises a third conveying mechanism 170 provided at the joining station d, the third conveying mechanism 170 comprising two third conveying members 151 arranged at intervals along the third direction F3. The auxiliary conveying mechanism 130 is further configured to reciprocate along the first direction F1 between the feeding station a, the heating station b, and the joining station d, so as to transfer the heated mold 200 to the second conveying mechanism 150 by means of the two third conveying members 151.

After the mold 200 is heated, the jacking device can be again in an ejected state to carry the mold 200 on the heating member 121 to move upward in the second direction F2. At this time, the supporting member is at the material moving position, and the bearing surface of the lifting mechanism 160 is flush with the bearing surface of the bearing member 131 at the material moving position. The carrier 131 is movable in the first direction F1 between the two heating members 121 disposed at intervals, and receives the heated mold 200 on the support roller 161 during the movement, thereby transferring the mold 200 to the second conveying mechanism 150 via the two third conveying members 151.

It should be noted that, the second conveying member 171 can autonomously move and has a certain transmission speed, and the transmission speed is faster and greater than the moving speed of the carrier member 131. It will be appreciated that if the heated mold 200 is directly placed on the second conveying member 171 by the carrier member 131, the mold 200 and the second conveying member being driven easily slide relatively, so that the mold 200 is scratched or damaged, thereby affecting the quality of the mold 200. And in the process of transferring the mold 200, collision and friction easily occur between the carrier 131 and the second conveyor having a greater speed, resulting in damage of components.

Thus, the third conveying mechanism 170 can have a transition effect between the bearing member 131 and the second conveying member 171, so that the possibility of relative sliding between the die 200 and the second conveying member 171 is reduced, and the transportation process of the die 200 is smoother and safer.

In the embodiment shown in fig. 1, the third conveying member 151 is of the same structure and material as the first conveying member 111, and is a roll, and the third conveying member 151 can be disposed on the third conveying mechanism 170 in an unpowered manner to support the mold 200 and enable the mold 200 to move more smoothly. At the same time, the third conveying member 151 may be disposed on the third conveying mechanism 170 at a certain initial speed, and it is understood that the initial speed is less than the speed at which the carrier 131 carries the mold 200 along the first direction F1 and the speed at which the second conveying member 171 is driven.

In some embodiments, the conveying surface of the third conveying mechanism 170 is flush with the bearing surface of the bearing 131 in the shift position; the conveying surface of the third conveying mechanism 170 is also flush with the conveying surface of the second conveying mechanism 150. It is understood that the conveying surface of the third conveying mechanism 170 refers to a plane in which a portion of the second conveying member 171 directly contacts the mold 200.

When the carrying surface of the carrying member 131, the carrying surface of the third conveying mechanism 170 and the carrying surface of the second conveying mechanism 150 at the material transferring position are flush, the mold 200 has continuity in the transportation process, and the mold 200 can be transferred more stably and smoothly.

Fig. 5 shows a schematic structural diagram of a cooling mechanism 140 according to an embodiment of the present application.

In some examples, the cooling mechanism 140 includes a plurality of cooling units disposed at sequential intervals along the first direction F1; the plurality of cooling units are located above the second conveying mechanism 150 in the second direction F2. The cooling unit located furthest upstream and the cooling unit located furthest downstream are each configured to cool down the mold 200 located on the second conveying mechanism 150 by means of a cooling gas. The remaining cooling units are configured for cooling the molds 200 located on the second conveyor 150 with a cooling liquid.

The term "disposed at intervals in this order" means that a plurality of cooling units are disposed in the first direction F1, and that every two cooling units do not contact each other. The purpose of setting the intervals of the cooling units is to utilize the interval distance between two cooling units to provide a time gap for the mold 200 to be formed to be stable, so that the mold 200 is prevented from being formed unevenly in the mold 200 due to the fact that the interval distance between the cooling units is too short at the cooling mechanism 140, and the forming precision of the mold 200 is reduced. Cooling the mold 200 at a gentle rate can make the molding inside the mold 200 more uniform.

On the other hand, the cooling units are arranged at intervals to avoid too concentrated cooling time of the die 200 at the cooling mechanism 140, so that the temperature change of the surface of the die 200 is too fast, and the temperature of the interior of the die 200 is not reduced in a short time, so that the overall cooling of the die 200 is uneven, and the quality of the molded die 200 is affected.

As shown in connection with fig. 1 and 4, both the cooling unit located furthest upstream and the cooling unit located furthest downstream are configured to cool down the mold 200 located on the second conveying mechanism 150 by means of a cooling gas. The remaining cooling units are configured for cooling the molds 200 located on the second conveyor 150 with a cooling liquid.

The cooling unit located at the most upstream uses the cooling gas to cool, and has the advantage of relatively low cooling speed, and 5, the high-temperature mold 200 transferred from the heating mechanism 120 is primarily cooled, so that the temperature change of the mold 200 can be gentle, and the molding of the mold 200 is easy.

The other cooling units are cooled by using the cooling liquid, and the advantage is that the specific heat capacity of the cooling liquid cooling medium is large, so that the cooling efficiency of cooling by using the cooling liquid is high, the effect of rapid cooling is achieved, the die 200 can rapidly reach the required cooling forming temperature in a short time, and the working efficiency of the thermoforming device 100 is improved. 0 is located the cooling unit of low reaches and uses the cooling gas to cool, and the benefit is that can further reduce the waste heat of mould 200 to flow through the wind stream and flow on mould 200 surface so that the mould 200 that passes the water-cooling of second cooling unit 142 can reach dry state promptly, the follow-up ejection of compact of being convenient for.

In the embodiment shown in fig. 4, the cooling mechanism 140 is provided with the baffle plates 143 on two sides in the first direction F1, one side of the baffle plate 143 is fixed on the cooling mechanism 140 in the second direction F2, and the baffle plates 5 are provided to prevent the cooling liquid sprayed by the rest of the cooling units from splashing outside the cooling mechanism 140, so that the neatness of the thermoforming device 100 can be ensured as much as possible, the cooling area of the mold 200 at the cooling mechanism 140 is more concentrated, and the cooling effect is stronger.

In addition, in the second direction F2, a water collecting tank is provided at the lower end of the cooling mechanism 140, and is located below the second conveying member, so that the cooling liquid used by the remaining cooling mechanism 140 to cool the mold 200 by 0 can be received, and environmental pollution caused by the cooling liquid can be avoided. Since the water collecting tank is disposed at the lower end of the second conveying mechanism 150, the structure of which is shielded by the second conveying mechanism 150 and is not the main structure to be described in the present application, corresponding reference numerals are not shown in the drawings and only the explanation is made here

In some embodiments, the spacing between the cooling unit located furthest upstream and its neighboring cooling units along the first direction F1 is a first spacing L1. The spacing between the cooling unit located furthest downstream and the cooling unit adjacent thereto is the second spacing L2. The first pitch L1 is larger than the second pitch L2.

Referring to fig. 1 and 6, the heated mold 200 sequentially passes through the cooling unit located at the most upstream, the rest of the cooling units, and the cooling unit located at the most downstream in the movement of the cooling units, that is, the heated mold 200 is sequentially cooled by the cooling gas, the cooling liquid, and the cooling gas.

The advantage of the first interval L1 being larger than the second interval L2 is that after the heated mold 200 is cooled by the cooling gas of the most upstream cooling unit, the heated mold 200 can be moved to the rest of the cooling units for cooling by the cooling liquid for a relatively long time, and the mold 200 is contacted with air in the process of moving from the most upstream cooling unit to the rest of the cooling units, so that a certain cooling effect is also achieved, and the problem that the heated mold 200 still has a higher temperature after being cooled by the cooling gas of the most upstream cooling unit, so that the cooling liquid is contacted with the surface of the high-temperature mold 200 to generate steam when the rest of the cooling units cool the mold 200 by the cooling liquid is avoided, thereby influencing the normal operation of the cooling mechanism 140. Setting the first pitch larger than the second pitch can make the cooling efficiency of the cooling mechanism 140 higher, thereby making the molding rate of the mold 200 faster.

The first cooling unit 141 adopts an air-cooled cooling method, and the air-cooled cooling method adopts a plurality of cooling fans to cool the mold 200, so that the mold 200 can be cooled by providing a relatively small number of cooling fans due to the strong fluidity of the gas.

In particular, in the embodiment shown in fig. 4, the first cooling unit 141 is provided with 6 cooling fans, and the number of the specific cooling fans may be determined according to the area and the volume of the mold 200 that needs to be cooled, so long as sufficient cooling of the mold 200 can be ensured, which is not limited herein.

Further, the cooling fan can adopt a multi-point control, and the multi-point control means that the number of the cooling fans operated can be controlled according to actual needs in the cooling process, so that the cooling of the cooling mechanism 140 is more intelligent and has more universality.

In the embodiment shown in fig. 4, the cooling units located most upstream and most downstream are the first cooling unit 141, and the other cooling units are referred to as the second cooling unit 142. The second cooling unit 142 uses water-cooled cooling of the cooling liquid, and the water-cooled cooling uses a plurality of spray heads, and since the fluidity of the liquid is not as strong as that of the gas, the cooling liquid is concentrated in cooling the mold 200, and therefore, a larger number of spray heads than the number of cooling fans in air-cooled cooling are required to be provided to satisfy the cooling requirement of the mold 200.

In particular to the embodiment shown in fig. 4, the second cooling unit 142 is provided with 12 spray heads. The number of the specific spray heads may be determined according to the area and the volume of the mold 200 to be cooled, so long as the mold 200 is sufficiently cooled, and the number is not limited herein.

Further, the spray head can adopt multi-point control, and the multi-point control means that the number of the spray heads operated can be controlled according to actual needs in the cooling process, so that the cooling of the cooling mechanism 140 is more intelligent and has more universality.

Referring to fig. 1, the cooling mechanism 140 further includes a water storage tank 144, where the water storage tank 144 is disposed outside the transmission path, and the cooling nozzle can be connected with the water storage tank 144, so that the cooling nozzle of the water storage tank 144 can continuously supply water to the cooling nozzle, and the cooling mechanism 140 can cool the mold 200 more coherently and has a better cooling effect.

In fig. 6, a protective cover 190 is further provided at the heating station b and the cooling station c, respectively, and since the heating plastic process and the cooling shaping process of the mold 200 are the most important two links for manufacturing the mold 200, the high temperature of the heating device has a certain risk. Therefore, the protective cover 190 is arranged on the two stations, so that the misoperation of operators can be prevented, the safety of the operators is protected, and the forming effect of the die 200 is better.
