Description

Technical Field

[0001] This utility model relates to the field of milk production equipment technology, and in particular to a peristaltic pump for milk conveying. Background Technology

[0002] Peristaltic pumps are typically used in milk production lines to transport milk. For food hygiene and safety, the peristaltic pump hoses are cleaned or replaced after production. Currently, the hose compression space in commercially available peristaltic pumps is constructed by screws securing the housing to the pump impeller. This requires removing the screws to remove the hose, necessitating tools for disassembly and assembly, making the process inconvenient, time-consuming, and labor-intensive for workers. Utility Model Content

[0003] The purpose of this utility model is to provide a peristaltic pump for milk delivery. This peristaltic pump for milk delivery has the advantages of simple structure, scientific design, and the ability to disassemble and assemble the hose without the need for tools. It is very convenient to disassemble and assemble, has high efficiency, and helps to reduce the labor intensity of workers.

[0004] The technical solution of this utility model is implemented as follows: A peristaltic pump for milk delivery, specifically comprising a mounting plate, a motor, a pump wheel, a pressure block, a locking slider, and a hose; the motor is fixed to the back of the mounting plate, and the motor shaft protrudes from the front of the mounting plate through the mounting plate; the pump wheel, which rotates synchronously with the motor shaft, is mounted on the motor shaft; the back of the pressure block is provided with at least two positioning pins, each positioning pin having a locking groove; the locking slider is linearly reciprocatingly mounted on the back of the mounting plate, and the locking slider has at least two locking... The mounting plate has at least two positioning holes; all positioning pins of the pressure block are inserted into all positioning holes of the mounting plate one by one, so that the locking groove of each positioning pin is exposed on the back of the mounting plate; all locking parts of the locking slider correspond to all positioning pins of the pressure block one by one, and the locking parts enter the locking groove of the corresponding positioning pin by the movement of the locking slider, so as to install the pressure block on the mounting plate, so that the pressure block and the pump wheel cooperate to form a hose extrusion space; both ends of the hose are positioned on the mounting plate, and the middle section of the hose is in the hose extrusion space.

[0005] This solution simplifies hose removal by simply pushing the locking slider to disengage its locking part from the corresponding locating pin's slot. Pulling the pressure block then separates it from the mounting plate, releasing the clamping pressure on the hose and making disassembly very convenient. For hose installation, first position both ends of the hose on the mounting plate, with the middle section passing around the pump wheel. Then, insert all the locating pins of the pressure block into the corresponding locating holes on the mounting plate. Finally, move the locking slider until its locking part enters the corresponding locating pin's slot, thus installing the hose. Neither hose installation nor removal requires tools, significantly improving efficiency and facilitating hose cleaning or replacement, thereby reducing worker fatigue.

[0006] The line connecting the center of the pump wheel and the center of the pressure block is parallel to the direction of reciprocating movement of the locking slider. A top pressure plate is provided on the side of the pressure block facing away from the pump wheel, and a mounting post is provided on the top pressure plate. A push plate is provided on the side of the top pressure plate facing away from the pressure block, and a through hole is provided on the push plate for the mounting post to pass through. A push spring is mounted on the mounting post, and this push spring is compressed between the top pressure plate and the push plate. This structure allows the locking slider to move automatically under the action of the push spring, causing its locking parts to enter the locking grooves of their corresponding positioning pins. Pushing the push plate allows the locking slider to overcome the force of the return spring, causing each locking part to disengage from the locking groove of its corresponding positioning pin.

[0007] Each locating pin has a pointed, conical end; each locating hole has a locating cylinder protruding from the back of the mounting plate along its edge; each locating cylinder has a notch for exposing the locating pin's locking groove, the depth of the notch being less than the radius of the locating cylinder. This causes the ends of the locating pins to push their corresponding locking parts as the locating pins are inserted into their corresponding locating holes, causing the locking slider to move as a whole against the force of the push spring. As each locating pin gradually penetrates deeper into the locating hole, the locking parts of the locking slider enter the locking grooves of their corresponding locating pins under the action of the push spring. This allows the locating block to be assembled with the mounting plate without manually pushing or pulling the locking slider, further improving the installation efficiency of the locating block.

[0008] The pressure block has an arc-shaped elongated structure, with positioning pins at both ends and the middle of the back of the pressure block. This improves the structural stability after the pressure block and the mounting plate are assembled.

[0009] The pump impeller includes two clamping plates and at least three rollers. The two clamping plates are arranged opposite each other. Each roller is rotatably mounted between the two clamping plates to assemble them together. Each clamping plate is synchronously connected to the motor shaft. All rollers are evenly distributed around the motor shaft, and the rotation axis of each roller is parallel to the axis of the motor shaft. The side of each roller facing away from the motor shaft combines with the two clamping plates to form a hose retaining groove. This design prevents the hose from detaching from the hose compression space during use, resulting in a more rational structure.

[0010] To facilitate hose installation, the mounting plate has a folded plate on the side of the pump wheel facing away from the pressure block, and two locking holes are provided on the folded plate; the two ends of the hose are respectively locked into the locking holes and positioned on the mounting plate.

[0011] To enhance the structural strength of this design, both ends of the folded plate section are bent to form structural reinforcing plates.

[0012] In order to enable the locking slider to be mounted on the back of the mounting plate in a linear reciprocating motion, a V-shaped recess is formed on the locking slider to avoid the motor. Two slide rails are symmetrically provided on both sides of the V-shaped recess on the locking slider. Two slide tracks are provided on the back of the mounting plate. The two slide rails of the locking slider are slidably installed in the two slide tracks respectively.

[0013] For ease of installation, mounting holes are provided on both sides of the pump wheel on the mounting plate.

[0014] The preferred motor is a DC geared motor.

[0015] The advantages of this utility model are: simple structure, scientific design, and the ability to disassemble and assemble the hose without the need for tools, which is very convenient, efficient and helps to reduce the labor intensity of workers. Attached Figure Description

Detailed Implementation

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a peristaltic pump for milk delivery in this embodiment includes a mounting plate 1, a motor 2, a pump wheel 3, a pressure block 4, a locking slider 5, and a hose 6. The motor 2 is a DC geared motor, fixed to the back of the mounting plate 1. The shaft of the motor 2 passes through the mounting plate 1 and protrudes from the front of the mounting plate 1. The pump wheel 3, which rotates synchronously with the shaft, is mounted on the shaft of the motor 2. The back of the pressure block 4 is provided with three positioning pins 41, each with a locking groove 42. The locking slider 5 is linearly reciprocating and mounted on the back of the mounting plate 1, and has three locking parts 51. The plate has three positioning holes 11. All positioning pins 41 of the pressure block 4 are inserted into the mounting plate 1 in a one-to-one correspondence with all positioning holes 11 of the mounting plate 1, so that the locking grooves 42 of each positioning pin 41 are exposed on the back of the mounting plate 1. All locking parts 51 of the locking slider 5 correspond to all positioning pins 41 of the pressure block 4. The locking parts 51 enter the locking grooves 42 of the corresponding positioning pins 41 by the movement of the locking slider 5, so as to install the pressure block 4 on the mounting plate 1, so that the pressure block 4 and the pump wheel 3 cooperate to form a hose extrusion space 7. Both ends of the hose 6 are positioned on the mounting plate 1, and the middle section of the hose 6 is in the hose extrusion space 7. This design allows for easy removal of the hose 6 by simply pushing the locking slider 5, causing its locking part 51 to disengage from the corresponding positioning pin 41's locking groove 42. Then, pulling the pressure block 4 separates it from the mounting plate 1, releasing the clamping pressure on the hose 6. When installing the hose 6, first position both ends of the hose 6 on the mounting plate 1, and then pass the middle section of the hose around the pump wheel 3. Next, insert all the positioning pins 41 of the pressure block 4 into all the positioning holes 11 of the mounting plate 1. Finally, move the locking slider 5 so that its locking part 51 enters the corresponding positioning pin 41's locking groove 42, thus completing the installation of the hose 6. The hose 6 can be installed and removed without the need for tools, greatly improving efficiency and facilitating cleaning or replacement, thus reducing the workload of workers.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the line connecting the center of the pump wheel 3 and the center of the pressure block 4 is parallel to the direction of reciprocating movement of the locking slider 5; a top pressure plate 12 is provided on the side of the pressure block 4 facing away from the pump wheel 3 on the mounting plate 1, and a mounting post 13 is provided on the top pressure plate 12; a push plate 52 is provided on the side of the top pressure plate 12 facing away from the pressure block 4 on the locking slider 5, and a through hole 53 is provided on the push plate 52 for the mounting post 13 to pass through; a push spring 8 is mounted on the mounting post 13, and the push spring 8 is compressed between the top pressure plate 12 and the push plate 52. This structure allows the locking slider 5 to move automatically under the action of the push spring 8, causing its locking part 51 to enter the locking groove 42 of its corresponding positioning pin 41; and pushing the push plate 52 allows the locking slider 5 to overcome the force of the push spring 8, causing each locking part 51 to exit the locking groove 42 of its corresponding positioning pin 41.

[0024] like Figure 2 , Figure 4 , Figure 5 As shown, the ends of each positioning pin 41 are made into pointed conical structures; each positioning hole 11 has a positioning cylinder portion 14 protruding from the back of the mounting plate 1 along its hole edge; each positioning cylinder portion 14 has a notch 15 for exposing the locking groove 42 of the positioning pin 41, and the depth of the notch 15 is less than the radius of the positioning cylinder portion 14. In this way, when the positioning pin 41 of the pressure block 4 is inserted into its corresponding positioning hole 11, the end of each positioning pin 41 will push the corresponding locking portion 51 to move, so that the locking slider 5 moves as a whole against the force of the pushing spring 8. As each positioning pin 41 gradually goes deeper into the positioning hole 11, under the action of the pushing spring 8, each locking portion 51 of the locking slider 5 will enter the locking groove 42 of its corresponding positioning pin 41. The pressure block 4 and the mounting plate 1 can be assembled together without manually pushing and pulling the locking slider 5, which further improves the installation efficiency of the pressure block 4.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the pressure block 4 has an arc-shaped elongated structure, and the positioning pins 41 are provided at both ends and the middle of the back of the pressure block 4. This makes the structure more stable after the pressure block 4 is assembled with the mounting plate 1.

[0026] like Figure 1 , Figure 3 , Figure 4As shown, the pump wheel 3 includes two clamping plates 31 and three rollers 32; the two clamping plates 31 are arranged opposite each other; each roller 32 is rotatably installed between the two clamping plates 31 to assemble the two clamping plates 31 together; each clamping plate 31 is synchronously connected to the rotating shaft of the motor 2; all rollers 32 are evenly distributed around the rotating shaft of the motor 2, and the rotation axis of each roller 32 is parallel to the axis of the rotating shaft of the motor 2; the side of each roller 32 facing away from the rotating shaft of the motor 2 combines with the two clamping plates 31 to form a hose limiting groove 33. In this way, the hose 6 will not detach from the hose compression space 7 during use, and the structure is more reasonable.

[0027] To facilitate the installation of hose 6, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the mounting plate 1 has a folding plate portion 16 on the side of the pump wheel 3 facing away from the pressure block 4, and two clamping holes 17 are provided on the folding plate portion 16; the two ends of the hose 6 are respectively clamped into the clamping holes 17 and positioned on the mounting plate 1, and clamping sleeves 61 are respectively fixed at the two ends of the hose 6 and clamped into the clamping holes 17.

[0028] To enhance the structural strength of this peristaltic pump for milk delivery, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the two ends of the folded plate portion 16 are each bent to form a structural reinforcing plate portion 18.

[0029] In order to allow the locking slider 5 to move linearly back and forth on the back of the mounting plate 1, as follows: Figure 2 , Figure 4 , Figure 5 As shown, a V-shaped recess 54 is formed on the locking slider 5 to avoid the motor 2. Two slide rails 55 are symmetrically arranged on both sides of the V-shaped recess 54 on the locking slider 5. Two slide tracks 19 are provided on the back of the mounting plate 1. The two slide rails 55 of the locking slider 5 are slidably installed in the two slide tracks 19 respectively.

[0030] For ease of installation, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, mounting plate 1 has mounting holes 110 on both sides of pump wheel 3. When in use, this milk conveying peristaltic pump is fixedly installed by screws passing through the mounting holes 110.
