[0056] A set of roller seat fixing grooves 103 are respectively formed on the upper surface of the chassis base 1, near the left and right ends. The set of roller seat fixing grooves 103 includes two roller seat fixing grooves 103 arranged side by side. The entire groove body is formed inside the upper surface of the chassis base 1, and the upper end opening of the groove body is formed on the upper surface of the chassis base 1.

[0057] Two revolving wheel seats 2 are provided at both ends of the upper surface of the chassis seat 1; Figure 7 As shown, a wheel base 2 is composed of two mirror-symmetrical wheel bases 2, and a wheel 3 is set between the two wheel bases 2. The center of one side of the wheel 3 is rotatably set on one of the wheel bases 2 through a rotating shaft rod, and the center of the other side of the wheel 3 is rotatably set on the other wheel base 2 through a rotating shaft rod.

[0058] A wheel base plate 201 is provided below the two wheel bases 2; screw holes are provided on both sides of the wheel base plate 201. Two wheel bases 2 are provided at each end of the upper surface of the chassis base 1. The screw holes provided on both sides of the wheel base plate 201 below each wheel base 2 are aligned with the two wheel base fixing grooves 103 in one group. A screw is inserted into the screw hole and then screwed into the wheel base fixing groove 103. The screw is tightly pressed against the wheel base fixing groove 103 to secure the wheel base 2. This also secures the position of the wheel 3 on the chassis base 1.

[0059] The screw is directly screwed into the wheel seat fixing groove 103, and the lower end of the screw is pressed against the bottom of the wheel seat fixing groove 103 to achieve fixation; however, this fixing method is prone to the screw becoming loose during the rotation of the wheel 3;

[0060] As a preferred embodiment, Figure 5As shown, the width of the upper end opening of the runner seat fixing groove 103 is set to be smaller than the width of the internal space of the runner seat fixing groove 103; the width of the upper end opening should be greater than the diameter of the rod body of the screw rod, and the width of the internal space of the runner seat fixing groove should be greater than the diameter of the rod cap of the screw rod; the installation position relationship between the screw rod and the runner seat fixing groove 103 is that the rod cap is located in the internal space of the runner seat fixing groove, and the side wall of the rod cap is just fitted on the side wall of the internal space of the runner seat fixing groove, and the rod body can pass out of the upper end opening and is fitted on the side wall of the upper end opening;

[0061] As shown, a chassis side edge stop 102 is arranged on each side near the upper surface of the chassis seat 1; Figure 3

[0062] Corresponding to the two ends of each runner seat fixing groove 103 and located in the chassis side edge stop 102, a screw rod insertion hole groove 1021 is arranged; the screw rod insertion hole groove 1021 is communicated with the internal space of the runner seat fixing groove 103, the groove bottom surface of the screw rod insertion hole groove 1021 is flush with the groove bottom surface of the runner seat fixing groove 103; and the diameter of the screw rod insertion hole groove 1021 is equal to the width of the internal space of the runner seat fixing groove 103; that is, the rod cap of the screw rod can pass through the screw rod insertion hole groove 1021;

[0063] When installing the screw rod, the rod cap is downward, and then the rod cap is placed into the screw rod insertion hole groove 1021; when the rod cap touches the groove bottom surface, the screw rod is moved to be located in the runner seat fixing groove 103, at this time, the rod cap is located in the internal space of the runner seat fixing groove 103, and the upper end of the rod body passes through the upper end opening of the runner seat fixing groove 103 and is higher than the upper surface of the chassis seat 1; due to the existence of the upper end opening, the rod cap cannot be separated from the runner seat fixing groove 103. Only need to move the screw rod to the position where the runner seat needs to be installed, and make the screw rod align with the screw rod hole on the runner seat bottom plate 201, pass the screw rod through the runner seat bottom plate 201, then pull up the screw rod, make the rod cap stop at the lower carding step of the upper end opening, screw the nut on the screw rod, and tighten the nut towards the runner seat bottom plate 201, tighten all the screw rods on each group of runner seats 2 at two ends, so that all the runner seats 2 at two ends can be fixed.

[0064] After the runner seat 2 is fixed, the position of the runner 3 on the runner seat 2 relative to the chassis seat 1 is also fixed; appropriate distance should be arranged between two runner seats 2 at each end, that is, appropriate distance should be arranged between two runners 3 at the same end; the first end of the roller mold 4 is placed on two runners 3 at one end; the second end of the roller mold 4 is placed on two runners 3 at the other end; the runner 3 rotates to drive the roller mold 4 to rotate; as shown, Figure 1 or Figure 7 ​As shown in the drawings, one of the rotors 3 at each end should be provided with a motor 5 to drive the rotor 3 to rotate; the motor 5 is arranged outside the rotor seat 2, the rotor of the motor 5 is connected to the shaft rod on one side of the rotor 3, and the rotation of the motor 5 can drive the rotor 3 to rotate; the arrangement between the motor 5 and the rotor 3 belongs to the prior art that can be mastered by those skilled in the art; how the motor 5 is connected with the rotor seat 2 and how the motor 5 can normally drive the rotor 3 are layout according to the actual situation of the rotor seat 2 by those skilled in the art. The two motors 5 at both ends should rotate at the same frequency and in the same direction.

[0065] The outer side walls at both ends of the drum mold 4 are provided with limiting structures on the contact surfaces with the circumferential side walls of the rotors 3; the limiting structures are used to limit the horizontal displacement of the drum mold 4 relative to the rotors 3 during centrifugal rotation.

[0066] As shown in the drawings, Figure 1 or Figure 4 or Figure 7 The limiting structure includes an annular groove 301 and a flange ring 401.

[0067] The annular groove 301 is centrally arranged in the circumferential side wall of the rotor 3; the flange ring 401 is arranged on the outer side wall near both ends of the drum mold 4.

[0068] When the outer side walls at both ends of the drum mold 4 contact with the circumferential side walls of the rotors 3 at both ends, the flange ring 401 can be detachably and movably embedded in the annular groove 301; due to the embedding action between the annular groove 301 and the flange ring 401, the limiting between the drum mold 4 and the rotor 3 can be formed without affecting the rotation of the drum mold 4 driven by the rotor 3, so as to avoid the possible horizontal displacement of the drum mold 4 relative to the rotor 3 during high-speed centrifugal rotation.

[0069] The rotor 3 can drive the drum mold 4 to rotate through the mutual friction between the rotor 3 and the drum mold 4; therefore, as shown in the drawings, Figure 4 and Figure 7 Friction lines 402 are arranged on both sides of the flange ring 401 and on the outer side walls of the drum mold 4; friction lines 402 are also arranged on both sides of the annular groove 301 and on the circumferential side walls of the rotor 3.

[0070] The friction lines 402 increase the contact friction force between the outer side walls of the drum mold 4 and the circumferential side walls of the rotor 3, so that the drum mold 4 is more easily rotated under the driving of the rotor 3.

[0071] If only rely on the above friction lines 402, the drum casting 4 can be driven by the rotating wheel 3, but when the rotating speed is very fast, the friction provided by the friction lines 402 may not be large enough; therefore, as a preferred embodiment, the tooth structure is arranged on both sides of the flange ring 401 and on the outer side wall of the drum casting 4; the tooth structure is also arranged on both sides of the annular groove 301 and on the circumferential side wall of the rotating wheel 3; the arrangement mode and structure of the above-mentioned tooth structure are the same as those of the tooth structure on the gear;

[0072] When the outer side wall of the drum casting 4 contacts the circumferential side wall of the rotating wheel 3, the tooth structures on the two walls are engaged with each other. In this way, under the action of the tooth engagement, the drum casting can be ensured to rotate under the driving of the rotating wheel regardless of the centrifugal rotating speed.

[0073] Embodiment 2

[0074] Based on the basis of embodiment 1, the positional relationship between the drum casting 4 and the rotating wheels 3 at both ends should be that the two ends of the drum casting 4 should be respectively placed on the two rotating wheels 3 at both ends; and in order to ensure the stability of rotation during centrifugation, the two ends of the drum casting 4 should not exceed the two rotating wheels 3 at both ends too much, nor should they be flush with the outer side of the rotating wheel 3; therefore, according to the length of the drum casting 4, the distance between the two rotating wheels 3 at both ends should be adjusted adaptively;

[0075] As shown in Figure 3 , this embodiment sets a plurality of rotating wheel seat fixing grooves 103 on the upper surface of the chassis seat 1 at equal intervals, and the screw insertion hole grooves 1021 are also arranged at both ends of each rotating wheel seat fixing groove 103 in each group.

[0076] In this way, the rotating wheel seat 2 can be moved on the chassis seat 1 according to the length of the drum casting 4, the distance between the two rotating wheel seats 2 at both ends can be adjusted, and the rotating wheel seat 2 can be fixed by using the rotating wheel seat fixing groove 103.

[0077] Embodiment 3

[0078] Based on the basis of embodiment 1, two rotating wheel seats 2 are arranged at both ends of the chassis seat 1, and a rotating wheel 3 is arranged on each rotating wheel seat 2; before the drum casting 4 is placed on the rotating wheel 3, the distance between the two rotating wheels 3 at each end should be adjusted; the distance between the two rotating wheels 3 at each end should be consistent; and the position of the rotating wheel 3 is determined by the position of the rotating wheel seat 2, so adjusting the distance between the two rotating wheels 3 is equivalent to adjusting the distance between the two rotating wheel seats 2;

[0079] In order to intuitively obtain the adjusted position distance when adjusting the distance between the two rotating wheel seats 2 at both ends, as shown in Figure 3As shown, the scale marks 104 are arranged on the upper surface of the chassis seat 1 at the edges of both ends. When moving the rotating wheel seat 2, the position of the rotating wheel seat 2 can be accurately adjusted by referring to the scale marks 104.
