A conductive slip ring is fixedly connected to the straight shaft. The inner ring of the conductive slip ring is fixedly connected to the straight shaft, and the outer ring of the conductive slip ring is fixedly connected to the first support frame. The conductive slip ring is connected to the lower mold body through a wire.

[0010] Furthermore, the pressing assembly includes an arc-shaped guide plate, a pressure plate, and a connecting plate; the bottom of the connecting plate is fixedly mounted on the base, the upper end of the connecting plate is fixedly connected to the arc-shaped pressure plate, and the end of the pressure plate away from the upper forming assembly is fixedly connected to the arc-shaped guide plate.

[0011] Furthermore, the upper forming component includes a third support frame, support rods, a mounting plate, an injection pipe, a cylinder, a heat insulation pipe, a heating cover, an upper mold body, and a top plate.

[0013] This invention also provides a hot-melt forming process for a uniform thickness urine bag catheter, which uses the aforementioned hot-melt forming device for the uniform thickness urine bag catheter to perform hot-melt forming, including the following steps: Step 1: During installation, insert and fix several forming rods to the left and right ends of the forming rod connecting block, and then place the forming rods and forming rod connecting blocks into the forming groove and slot. Step 2: The second support frame supports the outer and inner guide rails. The drive motor drives the straight shaft to rotate, which in turn drives the rotating plate to rotate. Under the limiting action of the limit slider, the outer guide rail, and the inner guide rail, the rotating plate makes a stable rotational motion.

Then, the lower mold body, heating cover and heat preservation pipe are activated. Glue is injected into the lower mold body through the injection pipe. Heating is achieved through the cooperation of the lower mold body and the heating cover. Forming is achieved through the cooperation of the lower mold body and the upper mold body. After that, the cylinder is activated to drive the mounting plate to slide up along the support rod. The mounting plate drives the heating cover and the upper mold body to move up, completing the hot melt forming of the uniform thickness urine bag catheter. Step 5: When the current forming mold rotates to the position above the inverted V-shaped plate, the bottom of the sliding rod contacts the inverted V-shaped plate. The inverted V-shaped plate lifts the sliding rod, which moves upward and contacts the bottom of the forming rod connecting block. The forming rod connecting block is then gradually pushed out of the slot, and the forming rod connecting block drives the forming rod to be pushed out of the forming groove, thereby automatically demolding the uniform thickness urine bag catheter.

[0014] Beneficial effects This invention uses two sets of lower forming molds to place the forming structure. The two sets of lower forming molds are intermittently driven by a dual-station drive component to move sequentially to below the upper forming component. The forming structure, which has rotated to contact the lower pressing component, is further pressed by a lower pressing component. The upper forming component and the lower forming mold cooperate to achieve glue injection and hot melt forming of the uniform thickness urine bag catheter. The lower forming mold is moved by the dual-station drive component to contact the lifting structure to achieve automatic ejection and unloading.

[0015] This invention not only enables simultaneous operation of multiple workstations, but also allows for the demolding of a uniformly thick urine bag catheter on a set of lower forming molds. During this process, a dual-station drive assembly can drive another set of lower forming molds to move below the upper forming assembly for glue injection and hot melt molding, ensuring the continuity of the work. Simultaneously, the demolding process is achieved by the dual-station drive assembly moving the lower forming molds to contact the lifting structure for automatic ejection and unloading, improving the degree of automation and enabling automatic demolding after molding.

[0016] This invention uses an arc-shaped guide plate to guide the forming rod connecting block and a pressure plate to press the forming rod connecting block, thus preventing the forming rod connecting block and the forming rod from not being installed in place. Attached Figure Description

The sliding rod (63) is located below the forming rod connecting block (42). In the initial state, the top of the sliding rod (63) does not contact the bottom of the forming rod connecting block (42). The lower end of the sliding rod (63) moves through the rotating plate (24).

7. A hot-melt forming process for a uniform thickness urine bag catheter, characterized in that, The hot-melt forming process using the uniform thickness urine bag catheter hot-melt forming device as described in claim 6 includes the following steps: Step 1: During installation, insert and fix several forming rods (43) into the left and right ends of the forming rod connecting block (42), and then place the forming rods (43) and forming rod connecting block (42) into the forming groove (44) and slot (45); Step 2: The second support frame (23) supports the outer guide rail (25) and the inner guide rail (27). The drive motor (21) drives the straight shaft (29) to rotate, and the straight shaft (29) drives the rotating plate (24) to rotate. Under the limiting action of the limiting slider (26), the outer guide rail (25) and the inner guide rail (27), the rotating plate (24) makes a stable rotational motion. Step 3: When the lower forming mold (4) rotates to the bottom of the lower pressing component (3), the top of the forming rod connecting block (42) contacts the bottom of the pressure plate (32). The arc-shaped guide plate (31) guides the forming rod connecting block (42), and the pressure plate (32) presses the forming rod connecting block (42) to prevent the forming rod connecting block (42) and the forming rod (43) from not being installed in place. Step 4: When the lower forming mold (4) rotates to the bottom of the upper forming component (5) for hot melt forming, start the cylinder (55). The cylinder (55) drives the mounting plate (53) to slide down along the support rod (52). The mounting plate (53) drives the heating cover (57) and the upper mold body (58) to move down, so that the upper mold body (58) and the lower mold body (41) directly below it close together. Then start the lower mold body (41), heating cover (57) and heat preservation pipe (56) ), and glue is injected into the lower mold body (41) through the injection tube (54). Heating is achieved through the cooperation of the lower mold body (41) and the heating cover (57). Molding is achieved through the cooperation of the lower mold body (41) and the upper mold body (58). Then, the cylinder (55) is started to drive the mounting plate (53) to slide upward along the support rod (52). The mounting plate (53) drives the heating cover (57) and the upper mold body (58) to move upward, thus completing the hot melt molding of the uniform thickness urine bag catheter; Step 5: When the current forming mold (4) rotates to the position above the inverted V-shaped plate (61), the bottom of the sliding rod (63) contacts the inverted V-shaped plate (61), and the inverted V-shaped plate (61) lifts up the sliding rod (63). The sliding rod (63) moves upward and contacts the bottom of the forming rod connecting block (42), and gradually pushes the forming rod connecting block (42) out of the slot (45). The forming rod connecting block (42) drives the forming rod (43) out of the forming groove (44), thereby automatically demolding the uniform thickness urine bag catheter.
