Description

Technical Field

[0001] This utility model belongs to the technical field of food processing equipment, specifically relating to a fixed structure for a feed pump body. Background Technology

[0002] Bread filling is a process in which fillings (such as chocolate, jam, cream, etc.) are injected into the inside of bread. By filling, different textures can be added to bread, satisfying the taste preferences of different consumers.

[0003] Currently, there are many types of bread filling machines on the market. Among them, the small desktop butter filling machine has become an indispensable piece of equipment in the baking industry due to its high efficiency, precision, and convenience. This type of filling machine mainly includes the filling machine body, the filling pump body (also called the filling head), and the filling hopper. The filling pump body is connected to the filling machine body, and the filling hopper is set on the filling pump body. Such devices can be found in the following documents: 1. Chinese Patent ZL202221280190.3, which discloses a filling machine for cheese bread processing; 2. The website "https: / / jianghu.taobao.com / guanglocal / 47761_ef3243bd545a61b91a136db6ea55b66f" displays a fully automatic filling machine; 3. The website "https: / / jianghu.taobao.com / guanglocal / 47761_2160e83867a5f79298dc4cd84fd49679" displays a cream puff filling machine.

[0004] The filling machines described in the above literature all feature detachable pump bodies mounted on the machine body. This detachable design facilitates cleaning and maintenance, ensuring hygiene and safety during food processing. Furthermore, the detachable design allows for easy replacement of pump bodies of different specifications to meet varying production needs, enhancing the equipment's flexibility and adaptability. However, in existing technologies, the pump body is typically secured to the machine body with multiple bolts (see references 2 and 3 above). Disassembly requires removing all bolts, making the process extremely inconvenient. In actual use, to ensure food hygiene and safety, the pump body must be frequently removed and reinstalled. This cumbersome disassembly method is not only time-consuming and labor-intensive, but also prone to bolt loosening and damage during frequent disassembly and reassembly, increasing maintenance costs and causing significant inconvenience for users.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] In view of the above-mentioned problems in the existing technology, this utility model proposes a fixing structure for the injection pump body. The purpose is to solve the problems of cumbersome disassembly and assembly, time-consuming and labor-intensive, and easy to damage the equipment due to the use of conventional bolt fixing method in bread filling machine. A new fixing method and structure are proposed.

[0007] This utility model achieves its technical objective through the following technical solution:

[0008] A fixing structure for a material injection pump body includes a mounting plate, a first pressure block, a second pressure block, a pressure nut, a first mounting seat, a rotating shaft, a second mounting seat, a first pressure screw, and a second pressure screw. The first and second pressure blocks are disposed on the top surface of the mounting plate, allowing the material injection pump body to be pressed against the top surface of the mounting plate. The first and second mounting seats are disposed on the bottom surface of the mounting plate. The first mounting seat and the second pressure block are vertically opposite each other, and the second mounting seat and the first pressure block are vertically opposite each other. The first mounting seat is slidably positioned vertically. A second pressure screw is provided, and a first pressure screw is slidably disposed vertically at the second mounting base. The first and second pressure screws pass through the first and second pressure blocks respectively in the vertical direction and are connected to a pressure nut at their tops. A rotating shaft is rotatably disposed on the first and second mounting bases and rotates in cooperation with the first and second pressure screws. When the rotating shaft rotates, it can drive the first and second pressure screws to slide vertically, and the pressure nuts are used to press or release the first and second pressure blocks on the injection pump body.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] This invention uses two pressure blocks mounted on a mounting plate to press the injection pump body onto the plate. The rotation of a rotating shaft drives a pressure screw to slide vertically, allowing the pressure blocks to tighten or loosen the injection pump body. This design eliminates the traditional multi-bolt fixing method, simplifying the assembly and disassembly process and making the disassembly and installation of the injection pump body more efficient and convenient. In actual operation, users do not need to tighten each bolt individually; they can quickly complete the assembly and disassembly work simply by rotating the handle, significantly saving time and labor costs and improving the user experience. Furthermore, frequent bolt removal and installation can easily lead to bolt loosening or damage. The fixing method of the pressure blocks and rotating shaft used in this invention effectively reduces the risk of component damage caused by bolt removal and installation, enhancing the overall stability and reliability of the equipment. Through the synergistic action of the eccentric wheel and the pressure screw, the injection pump body can be firmly pressed onto the mounting plate, ensuring smooth operation of the equipment during injection, reducing malfunctions that may be caused by loose components, and lowering maintenance costs and repair frequency.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0028] like Figures 1 to 11 As shown, this utility model proposes a fixing structure for an injection pump body, which includes a mounting plate 1, a first pressure block 3, a second pressure block 4, a pressure nut 5, a first mounting base 7, a rotating shaft 8, a second mounting base 9, a first pressure screw 10, and a second pressure screw 11. The first pressure block 3 and the second pressure block 4 are provided on the top surface of the mounting plate 1, and the first pressure block 3 and the second pressure block 4 can press the injection pump body onto the top surface of the mounting plate 1. The first mounting base 7 and the second mounting base 9 are provided on the bottom surface of the mounting plate 1. The first mounting base 7 and the second pressure block 4 are vertically opposite each other, and the second mounting base 9 and the first pressure block 3 are vertically opposite each other. The first mounting base 7 is vertically... A second pressure screw 11 is slidably disposed in the direction of the second mounting base 9, and a first pressure screw 10 is slidably disposed in the vertical direction at the second mounting base 9. The first pressure screw 10 and the second pressure screw 11 pass through the first pressure block 3 and the second pressure block 4 respectively in the vertical direction and are respectively connected to a pressure nut 5 at their top. A rotating shaft 8 is rotatably disposed on the first mounting base 7 and the second mounting base 9 and rotates in cooperation with the first pressure screw 10 and the second pressure screw 11. When the rotating shaft 8 rotates, it can drive the first pressure screw 10 and the second pressure screw 11 to slide in the vertical direction, and the pressure nut 5 is used to realize the pressing or loosening of the first pressure block 3 and the second pressure block 4 on the injection pump body.

[0029] It should be noted that in existing bread filling machine designs, the filling pump body is typically fixed to the machine body with multiple bolts. Each time the filling pump body is disassembled and reassembled, these bolts must be removed one by one, a process that is extremely tedious and inconvenient. In actual food processing scenarios, to ensure hygiene and safety, the filling pump body needs to be frequently disassembled and reassembled. This complex disassembly method is not only time-consuming and labor-intensive, but also prone to bolt loosening or even damage during frequent disassembly and reassembly. This increases equipment maintenance costs and causes considerable inconvenience to users. This invention utilizes two pressure blocks mounted on the mounting plate 1 to press the filling pump body onto the mounting plate 1. The rotation of the rotating shaft 8 drives the first pressure screw 10 and the second pressure screw 11 to slide vertically, thereby achieving the pressing or loosening of the pressure blocks on the filling pump body. Thus, when disassembling and reassembling the filling pump body, there is no need to tighten the bolts; simply rotating the rotating shaft 8 is sufficient, making disassembly and reassembly more efficient.

[0030] Furthermore, the fixing structure also includes a handle 6, which is located on one side of the mounting plate 1 and fixedly connected to one end of the rotating shaft 8. By rotating the handle, the rotating shaft 8 can be driven to rotate, thereby enabling the pressing or releasing operation of the injection pump body.

[0031] In a preferred embodiment, an eccentric wheel 14 is provided on the rotating shaft 8, and the rotating shaft 8 is rotatably engaged with the first pressure screw 10 and the second pressure screw 11 via the eccentric wheel 14. With this arrangement, when the rotating shaft 8 rotates, the eccentric wheel 14 rotates accordingly, thereby pushing the first pressure screw 10 and the second pressure screw 11 to slide in the vertical direction. It should be understood that the arrangement of the eccentric wheel 14 is only a preferred arrangement, and other arrangements can also be adopted. For example, the shape of the rotating shaft 8 at the corresponding position can be changed without having to additionally provide the eccentric wheel 14 or other structures.

[0032] In a preferred embodiment, the first pressure screw 10 and the second pressure screw 11 have the same structure, both including a sliding head 1101. The sliding head 1101 is slidably disposed at the first mounting base 7 and the second mounting base 9. A circular hole 1104 is formed at the sliding head 1101, and the central axis of the circular hole 1104 is parallel to the rotation axis of the rotating shaft 8. An eccentric wheel 14 is disposed in the circular hole 1104. With this arrangement, when the rotating shaft 8 rotates, it will drive the eccentric wheel 14 to rotate synchronously. Since the eccentric wheel 14 is installed in the circular hole 1104, its eccentric structure will generate an eccentric force during rotation. Since the first pressure screw 10 and the second pressure screw 11 are slidably disposed in the vertical direction, the eccentric wheel 14 will use this eccentric force to push the first pressure screw 10 and the second pressure screw 11 to slide in the vertical direction during rotation.

[0033] Furthermore, both the first pressure screw 10 and the second pressure screw 11 include a sliding rod section 1102 and a connecting screw section 1103. Both the first pressure screw 10 and the second pressure screw 11 are fixedly connected to the pressure nut 5 through the connecting screw section 1103. The sliding rod section 1102 passes through the mounting plate 1 in the vertical direction. Both the first pressure block 3 and the second pressure block 4 have vertical through holes 15. The pressure nut 5 includes a first shaft section 501 and a second shaft section 502. The diameter of the first shaft section 501 is larger than the diameter of the vertical through hole 15. The second shaft section 502 below the first shaft section 501 is located inside the vertical through hole 15 (its diameter is slightly smaller than the diameter of the vertical through hole 15). Since the first pressure screw 10 and the second pressure screw 11 are fixedly connected to the pressure nut 5, when the first pressure screw 10 and the second pressure screw 11 slide in the vertical direction, the pressure nut 5 also moves in the vertical direction. Since the diameter of the first shaft section 501 is larger than the diameter of the vertical through hole 15, when the pressure nut 5 moves downward in the vertical direction, it can exert downward pressure on the corresponding pressure block, thereby achieving the pressure block to press the injection pump body. When the pressure nut 5 moves upward, this pressing force is released. At this time, the pressure block is in a loose state, and the injection pump body can be easily removed.

[0034] More specifically, such as Figure 5 As shown, a connecting hole 503 is formed on the pressure nut 5. The connecting hole 503 is a downward-opening blind hole with an internal thread. An external thread matching the internal thread is formed on the connecting screw section 1103. The pressure nut 5 is connected to the connecting screw section 1103 through its connecting hole 503. Furthermore, the diameter of the sliding rod section 1102 is larger than the diameter of the connecting screw section 1103 and slightly smaller than the diameter of the vertical through hole 15. The sliding rod section 1102 is at least partially located within the vertical through hole 15.

[0035] To better achieve the purpose of this utility model, a second slot 13 is formed at the first pressing block 3, and a first slot 12 is formed at the second pressing block 4. The first pressing block 3 and the second pressing block 4 press the injection pump body onto the mounting plate 1 through the second slot 13 and the first slot 12. The first slot 12 and the second slot 13 are opposite each other in the left-right direction, and the first slot 12 and the second slot 13 form openings on their front sides. This arrangement allows for easy insertion of the locking parts on the injection pump body into the first slot 12 and the second slot 13 through the openings, without requiring the first pressing block 3 and the second pressing block 4 to be removed.

[0036] In a preferred embodiment, a groove 17 is formed in the middle of the first mounting base 7. Screw holes 18 are provided on the body of the first mounting base 7 on both sides of the groove 17. A through-hole rotary support hole 19 is formed in the middle of the groove 17. A rotating shaft 8 is rotatably disposed within the rotary support hole 19. The sliding head 1101 of the second pressure screw 11 is slidably disposed within the groove 17. The sliding head 1101 preferably adopts a square slider structure. The first mounting base 7 is fixed to the mounting plate 1 by bolts that match the screw holes 18. In a preferred embodiment, the bolts that match the screw holes 18 have bolt heads 22. When the first mounting base 7 is fixed to the mounting plate 1, the bolt heads 22 are located on the top surface of the mounting plate 1. The second pressure block 4 also has guide holes 16 on both sides of the vertical through hole 15. The guide holes 16 are used to cooperate with the bolt heads 22. The size of the bolt heads 22 is slightly smaller than the guide holes 16. With this setup, when the rotating handle 6 loosens the second pressure block 4, the second pressure block 4 will not be displaced in the horizontal direction due to the combined action of the two bolt heads 22 and the bolt that matches the bolt hole 18 located in the middle of them. That is, this loosening is only for the vertical direction. In this way, it is possible to ensure that the tightening operation can be completed by simply rotating the handle 6 without straightening the second pressure block 4.

[0037] Preferably, the bottom of the mounting plate 1 is also provided with a plurality of support legs 2. The body of the first mounting base 7 extends downward to form a support leg extension 20, the bottom of which is flush with the bottom of the support leg 2. With this arrangement, the first mounting base 7 itself also functions as a support leg 2. Since the first mounting base 7 is close to the handle 6, the support leg extension 20 ensures the stability of the entire device when the handle 6 is rotated.

[0038] It should be noted that the second mounting base 9 and the first pressure block 3 are also set in a similar manner to the first mounting base 7 and the second pressure block 4. The main differences are: 1) the second mounting base 9 does not have a support leg extension 20, that is, the second mounting base 9 is fixed to the bottom surface of the mounting plate 1 in a suspended manner; 2) the sliding groove 17 of the second mounting base 9 is set opposite to the sliding groove 17 of the first mounting base 7.

[0039] It should also be noted that, see Figure 3 Only a portion of the mounting plate 1, such as the injection pump body mounting area I, is used to install the injection pump body. The remaining area of ​​the mounting plate 1 is mainly used to install the injection machine body, i.e. Figure 3 The shown is the installation area II of the injection machine body.

[0040] In a preferred embodiment, the eccentric wheel 14 is limited on both sides by spring clips 21. The spring clips 21 employ a plate-type spring clip design. This type of spring clip 21 has the advantage of occupying less space, thus achieving effective limitation of the eccentric wheel 14 without significantly increasing the size of the equipment. At the same time, the plate-type spring clips 21 also have the advantage of convenient installation and removal, which allows for quick completion of the corresponding operations when adjustment or maintenance of the eccentric wheel 14 is required, thereby improving the maintenance efficiency of the equipment.

[0041] It should also be noted that the rotating shaft 8 is also equipped with a locking structure to ensure that the pressure block is stably pressed after rotating into position. This design is common in existing technologies and will not be described in detail here.

[0042] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
