[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please refer to Figures 1-3. In this embodiment of the present invention, a feeding mechanism for thermoplastic tube production includes a feeding assembly 1 consisting of a main unit 101, a support plate 102, a conveying roller 103, and an upper pressure roller 104. The support plate 102 is symmetrically fixed to the top of the main unit 101. The conveying roller 103 and the upper pressure roller 104 are vertically parallel and distributed between the two support plates 102. The rotating shaft of the conveying roller 103 is rotatably connected to the support plate 102, and one side of the rotating shaft of the conveying roller 103 extends to the outside of the support plate 102 and is connected to a sprocket 106. The sprocket 106 is connected to the drive structure inside the main unit 101 through a chain 107.

[0028] The upper pressure roller 104 has bearing bases that slide vertically with the support plate 102 at both rotating ends. An electric push rod 105 is fixedly installed on the top of the support plate 102, and the output end of the electric push rod 105 is fixedly connected to the top of the bearing base.

[0029] The top of the main unit 101 has a groove 108 between the two support plates 102. An anti-deviation component 2 extending to the front and rear ends of the conveying roller 103 and the upper pressure roller 104 is provided inside the groove 108. The anti-deviation component 2 is used to provide a limiting guide for the thermoplastic tube passing through the middle of the conveying roller 103 and the upper pressure roller 104.

[0030] Anti-deviation component 2 includes an adjustable limit unit and a position adjustment unit;

[0031] Adjustable limit units are used to provide limit guidance for thermoplastic tubes of different sizes;

[0032] The position adjustment unit is used to adjust the horizontal and longitudinal relative positions of the adjustable limit unit with the conveyor roller 103 and the upper pressure roller 104.

[0033] The adjustable limit unit includes a cross-shaped movable seat 201, a fixed guide rod 202, a bidirectional screw 203, a first handwheel 204, an adjusting seat 205, and a limit rod 206;

[0034] The cross-shaped movable seat 201 is located inside the groove 108 and the bottom of the cross-shaped movable seat 201 is attached to the bottom of the inner wall of the groove 108. The two sides of the fixed guide rod 202 are fixedly connected to the two sides of the inner wall of the groove 108 and pass through the top horizontal part of the cross-shaped movable seat 201.

[0035] The bidirectional screw 203 is rotatably connected to the top horizontal part of the cross-shaped movable seat 201, and one side of the bidirectional screw 203 extends to the outside of the main unit 101 and is fixedly connected to the first handwheel 204.

[0036] Two adjusting seats 205 are symmetrically arranged on the top horizontal part of the cross-shaped movable seat 201. The two adjusting seats 205 are sleeved on the outside of the fixed guide rod 202 and the bidirectional screw 203. The limiting rod 206 is symmetrically rotated and connected to the top of the adjusting seat 205 with the conveying roller 103 and the upper pressure roller 104 as the center.

[0037] The first handwheel 204 drives the bidirectional screw 203 to rotate, which drives the two adjusting seats 205 to move closer or further apart, thereby adjusting the distance between the limiting rods 206 on the two adjusting seats 205, thus achieving the limiting and guiding of thermoplastic tubes of different sizes.

[0038] The position adjustment unit includes a threaded rod 207 and a second handwheel 208;

[0039] One side of the threaded rod 207 is rotatably connected to the inner wall of the groove 108, and the other side of the threaded rod 207 passes through the bottom transverse part of the cross-shaped movable seat 201, the main unit box 101 and the outer side of the main unit box 101 in sequence, and the second handwheel 208 is fixed to the other side of the threaded rod 207.

[0040] The threaded rod 207 is threadedly connected to the cross-shaped movable seat 201 and rotatably connected to the main unit housing 101. The rotation of the threaded rod 207 is used to drive the overall movement of the cross-shaped movable seat 201, the adjusting seat 205, and the limiting rod 206.

[0041] In this embodiment, the feeding assembly 1 is used as follows when conveying the thermoplastic tube:

[0042] After molding and cooling, the thermoplastic tube passes between the conveying roller 103 and the upper pressure roller 104. The electric push rod 105 can adjust the height of the upper pressure roller 104, thus maintaining good clamping force for thermoplastic tubes of different diameters. At the same time, the drive structure inside the main unit 101 (the drive structure consists of a drive motor and a drive sprocket) is activated, thereby driving the chain 107 to drive the transmission. The chain 107 drives the sprocket 106 and the conveying roller 103 to rotate. The conveying operation of the thermoplastic tube can be realized by the friction between the conveying roller 103 and the thermoplastic tube, and the upper pressure roller 104 assists in the rotation.

[0043] During the above operation, the front and rear ends of the thermoplastic tube will pass through the middle of the two sets of limiting rods 207 respectively. The limiting rods 207 can limit and guide the trajectory of the thermoplastic tube, which can effectively prevent the thermoplastic tube from deviating.

[0044] Meanwhile, when conveying thermoplastic pipes of different diameters, the spacing of the limiting rods 207 can be adjusted. By rotating the first handwheel 204, the first handwheel 204 drives the bidirectional screw 203, and the bidirectional screw 203 drives the two adjusting seats 205 to move closer or further apart, thereby realizing the adjustment of the spacing of the limiting rods 207.

[0045] In addition, the conveying path of the thermoplastic tube is sometimes not aligned with the middle section of the conveying roller 103 and the upper pressure roller 104. In this case, the second handwheel 208 can be rotated, which drives the threaded rod 207 to rotate. The bidirectional screw 203 drives the cross-shaped moving seat 201, the bidirectional screw 203, the adjusting seat 205, and the limiting rod 206 to move as a whole, so that the position of the limiting rod 206 can be adapted to different conveying paths.

[0046] The combination of these multiple components can effectively improve the applicability of the device.

[0047] Please refer to Figures 1-3. The main unit 101 and the bidirectional screw 203 are respectively provided with a through-hole 109 for the bidirectional screw 203 to pass through. The outer side of the bidirectional screw 203 is symmetrically formed with two sections of threads in opposite directions around the cross-shaped moving seat 201. The inner side of the two adjusting seats 205 is formed with internal thread holes that match the two sections of threads.

[0048] In this embodiment: the structure of the through-hole 109 ensures that the movement of the bidirectional screw 203 does not interfere with the main unit housing 101;

[0049] The two sections of the double-ended screw 203 with opposite helical directions on the outer side are used to realize the synchronous and opposite-direction movement adjustment operation of the adjusting seat 205;

[0050] It should also be noted that the fixed guide rod 202 is used to guide and limit the movement of the adjusting seat 205 and the cross moving seat 201.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
