[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] refer to Figures 1 to 6 This embodiment provides a peristaltic pump for a food printer, including a pump housing 1, a central hole 2 located in the middle of the pump housing 1, a bracket 3 rotatably located in the middle of the pump housing 1, a roller 4 rotatably located in the bracket 3, a motor 5 for driving the bracket 3 to rotate, pipe holes 6 located on both sides of the pump housing 1 and connected to the central hole 2, a pump pipe 7 for passing through the pipe holes 6 and fitting with the roller 4, and a sealing plate 8 detachably located on one side of the pump housing 1. The pump housing 1 has a square groove 9 at the pipe hole 6, and a locking block 10 is inserted into the square groove 9 of the pump housing 1. The locking block 10 is arc-shaped on the side near the pipe hole 6.

[0019] The adjusting block 11 is slidably connected in the middle of the pump housing 1. The adjusting block 11 is provided with an adjusting mechanism for fixing the adjusting block 11 in the middle of the pump housing 1. The bottom of the adjusting block 11 is U-shaped, and the shape of the joint between the locking block 10 and the pipe hole 6 after it is inserted into the pump housing 1 is circular.

[0020] In use, first pass the pump tube 7 through the pipe hole 6 on one side of the pump housing 1, and then pass it out through the pipe hole 6 on the other side. Press the pump tube 7 inside the pump housing 1 towards the central hole 2. After that, press the bracket 3 with rollers 4 into the pump housing 1. The rollers 4 on the outside of the bracket 3 will squeeze and fit the pump tube 7. Then pull the pump tube 7 to both sides. At this time, insert the locking block 10 into the square groove 9. One side of the locking block 10 will fit and fit the outside of the pump tube 7. Then install the motor 5 on the other side of the pump housing 1 and seal the pump housing 1 with the sealing plate 8 on one side. The installation of the pump housing 1 is now complete. This peristaltic pump can be used.

[0021] When it is necessary to replace the pump tube 7 with a different size, the position of the adjusting block 11 can be moved by adjusting the mechanism, so that the roller 4 can be used with pump tubes 7 of different diameters.

[0022] The pump pipe 7 is provided with a raised outer ring 12 at the pipe hole 6. The pump housing 1 and the locking block 10 are provided with an inner groove 13 for locking the raised outer ring 12. When installing the pump pipe 7, the pump pipe 7 is inserted into the pipe hole 6 of the pump housing 1 on both sides, and then the middle part of the pump pipe 7 is pressed towards the middle hole 2 of the pump housing 1. Then, the raised outer ring 12 of the pump pipe 7 is pressed down to lock the raised outer ring 12 of the pump pipe 7 into the inner groove 13 of the pump housing 1, thereby strengthening the fixation of the pump pipe 7 and reducing the displacement of the pump pipe 7.

[0023] The adjustment mechanism includes an adjustment rod 401 that slides longitudinally in the middle of the adjustment block 11, a slider 402 that slides laterally in the middle of the adjustment block 11, an extension block 403 located on the side of the slider 402 near the adjustment rod 401, a sloping groove 404 located on the extension block 403 and in contact with the bottom of the adjustment rod 401, a tip 405 located on the side of the slider 402 away from the extension block 403, and a spring 406 located between the tip 405 and the slider 402. The pump housing 1 has a toothed groove 407 located on the side of the slider 402 that engages with the tip 405.

[0024] When the position of the adjusting block 11 needs to be moved up and down, press the adjusting rod 401 down. The adjusting rod 401 moves down. Since the bottom of the adjusting rod 401 is engaged with the inclined groove 404 on one side of the slider 402, after the adjusting rod 401 moves down, the extension block 403 and the slider 402 will move away from the tooth groove 407. At this time, after the adjusting block 11 is moved up and down to the appropriate position, release the adjusting rod 401. Under the action of the spring 406, the slider 402 will move to one side. The tip 405 on one side of the slider 402 will be inserted into the tooth groove 407 for fixed engagement. When changing the size of the pump tube 7, the adjusting block 11 can be moved to adjust the distance between the roller 4 and the adjusting block 11, so as to achieve the use of pump tubes 7 of different sizes.

[0025] The pump pipe 7 is fixed with gears 14 on both sides of the pump casing 1, and the pump pipe 7 is provided with an external protrusion 15 at the gear 14.

[0026] Gear 14 is inserted into both sides of pump tube 7. The middle part of gear 14 will cooperate with the outer protrusion 15. After a period of use, the sealing plate 8 can be removed, and then the adjusting block 11 can be moved to the top. Then, the gear 14 can be rotated to drive the pump tube 7 to rotate at a certain angle, so as to avoid the pump tube 7 being squeezed by the roller 4 for a long time in the same position, thereby extending the service life of the pump tube 7. When used in conjunction with the adjusting mechanism, the pump tube 7 can be rotated quickly without removing the roller 4.
