Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection equipment technology, and in particular to a raw material injection device. Background Technology
[0002] In the field of automated filling of sauce products, existing technologies typically use an anti-clogging structure combining piston pushing and a reversing valve. A pneumatic plunger pump drives the sauce for quantitative filling, and the synergistic action of the conveying cylinder and the reversing valve enables continuous operation. For example, the filling cylinder piston draws the sauce into the conveying cylinder cavity, and then the reversing valve switches the channel to push the sauce to the filling outlet. However, in traditional filling equipment, sauce residue can form on the filling head due to its adhesiveness. During high-speed continuous filling, residual sauce drips onto the conveyor belt surface or the sealing edge of the packaging box due to inertial swaying or gravity caused by the conveyor belt movement. This forms a hard-to-remove, solidified sauce layer on the equipment surface, which is difficult to clean. Furthermore, the dripped sauce may seep into the heat-sealing area of the packaging box, reducing the seal strength. Utility Model Content
[0003] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a raw material filling device, comprising:
[0004] A storage hopper containing a limited quantity of raw materials;
[0005] A filling mechanism, wherein the filling mechanism is provided with at least one set, and the inlet of the at least one set of the filling mechanism is connected to the storage hopper;
[0006] A material blocking mechanism, which is connected to the discharge port of the filling mechanism;
[0007] The material-stopping mechanism includes:
[0008] First power unit;
[0009] The material blocking part includes a discharge block and a material blocking rod. The upper part of the discharge block is provided with a feed hole, which is connected to the discharge port of the filling mechanism. The lower part of the discharge block is provided with a discharge hole corresponding to the feed hole. The material blocking rod is wrapped inside the material blocking part. The material blocking rod is provided with a radially penetrating discharge channel corresponding to the feed hole and the discharge hole. The material blocking rod is driven to rotate around its own circumference by a first power device.
[0010] This invention uses a first power device to drive a baffle rod to rotate circumferentially, thereby controlling the connection between the discharge channel and the inlet and outlet holes. After filling is completed, the baffle rod can immediately rotate to the channel misalignment position to cut off the sauce flow path, thus blocking any residual material that may drip from the filling head due to gravity shaking, thereby reducing equipment surface contamination and packaging box sealing leakage.
[0011] Furthermore, the first power unit is a linear drive unit; the material stopping mechanism also includes a transmission mechanism connected to the first power unit;
[0012] The transmission mechanism includes:
[0013] The rack is driven to move linearly by the first power device;
[0014] A gear that meshes with a rack, the gear being mounted at one end of a stop bar.
[0015] Furthermore, the transmission mechanism also includes a guide block having a guide groove that matches the rack away from the gear side, and the rack slides within the guide groove.
[0016] Furthermore, the guide block is provided with a pulley corresponding to the guide groove, and the pulley is in contact with the side of the rack away from the gear.
[0017] The rack is driven to move linearly by the first power device, which in turn drives the gear to rotate, thereby rotating the stop rod. When the rack moves, the guide groove of the guide block and the pulley work together to constrain the linear motion trajectory of the rack, which can improve the motion accuracy of the rack. At the same time, the rolling contact between the pulley and the rack reduces the motion friction of the rack.
[0018] Furthermore, the injection device also includes a lifting mechanism, which drives the material blocking mechanism to move vertically.
[0019] The lifting mechanism includes:
[0020] Second power unit;
[0021] A lifting mechanism is provided, which is connected to a second power device, and the material blocking mechanism is integrally mounted on the lifting mechanism.
[0022] Furthermore, the lifting mechanism includes:
[0023] The eccentric wheel is driven to rotate eccentrically by a second power device;
[0024] A crank, one end of which is fitted onto the outside of an eccentric wheel;
[0025] A carriage is connected to the end of the crank away from the eccentric wheel, and the material stop mechanism is mounted on the carriage.
[0026] Furthermore, the lifting mechanism also includes a fixed part, on which the second power device is fixedly installed; a second guide rod is provided at the bottom of the slide, and the second guide rod is slidably engaged with the fixed part.
[0027] The second power unit drives the eccentric wheel to generate eccentric rotation, which is then converted into the vertical linear motion of the carriage through crank transmission. This adjusts the distance between the material blocking mechanism and the conveyor belt, thus adapting to containers of different heights. At the same time, the sliding constraint between the second guide rod and the fixed part improves the motion accuracy of the material blocking mechanism.
[0028] This utility model has the following advantages:
[0029] This invention uses a first power device to drive a baffle rod to rotate circumferentially, thereby controlling the connection between the discharge channel and the inlet and outlet holes. After filling is completed, the baffle rod can immediately rotate to the channel misalignment position to cut off the sauce flow path, thus blocking any residual material that may drip from the filling head due to gravity shaking, thereby reducing equipment surface contamination and packaging box sealing leakage.

[0046] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0047] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
[0048] As described in the background section, traditional filling equipment can leave residue on the filling head due to the adhesive nature of the sauce during filling. During high-speed continuous filling, the residual sauce may drip onto the surface of the conveyor belt or the sealing edge of the packaging box due to the inertial swaying caused by the movement of the conveyor belt or the effect of gravity. This can form a hardened sauce layer on the equipment surface that is difficult to remove and clean. In fact, the dripped sauce may even seep into the heat-sealing area of the packaging box, reducing the sealing strength.
[0049] Example 1:
[0050] Therefore, in order to solve the above-mentioned technical problems existing in the prior art, this embodiment provides a raw material injection device, such as... Figure 1 As shown, the infusion device may include:
[0051] Storage hopper 200, which stores raw materials in a limited quantity;
[0052] The filling mechanism 400 is provided with at least one set of filling mechanisms, and the inlet of the at least one set of filling mechanisms is connected to the storage hopper;
[0053] A material blocking mechanism 300 is connected to the discharge port 410 of the injection mechanism;
[0054] like Figure 2 As shown, the material blocking mechanism includes:
[0055] First power unit 310;
[0056] Material stop 340, such as Figure 3 , 4 As shown, the material blocking part includes a discharge block 342 and a material blocking rod 343. The upper part of the discharge block is provided with a feed hole 342A, which is connected to the discharge port of the filling mechanism. The lower part of the discharge block is provided with a discharge hole 342B corresponding to the feed hole. The material blocking rod is wrapped inside the material blocking part. The material blocking rod is provided with a radially penetrating discharge channel 343A corresponding to the feed hole and the discharge hole. The material blocking rod is driven to rotate around its own circumference by a first power device.
[0057] like Figure 5 As shown, in this embodiment, during injection, the first power device drives the baffle rod to rotate forward by a preset angle, so that the discharge channel is connected to the inlet and outlet. The injection mechanism draws the raw material from the storage hopper and discharges it through the discharge channel, thus realizing the injection of the raw material. Figure 6 As shown, after the injection is completed, the first power unit drives the baffle rod to rotate in the opposite direction so that the discharge channel is misaligned with the discharge hole and the inlet hole, blocking the flow path of the raw material and thus blocking the residual raw material.
[0058] In this embodiment, the first power device drives the baffle rod to rotate circumferentially, thereby controlling the connection between the discharge channel and the inlet and outlet. After filling is completed, the baffle rod can rotate to the channel misalignment position to cut off the sauce flow path, thereby blocking the residual raw materials that may drip in the filling head due to gravity shaking, thus reducing the problem of equipment surface contamination and packaging box sealing leakage.
[0059] For example, the first power device can be a linear drive device, such as a cylinder, electric cylinder, hydraulic cylinder, etc.; in this case, the material blocking mechanism may also include a transmission mechanism 320, which is connected to the first power device.
[0060] like Figure 7 As shown, the transmission mechanism includes:
[0061] The rack 322 is driven to move linearly by the first power device;
[0062] Gear 323, which meshes with a rack, is mounted at one end of a stop bar.
[0063] For example, the transmission mechanism may further include a guide block 321 having a guide groove 321A that matches the rack away from the gear side, and the rack slides within the guide groove.
[0064] For example, the guide block may be provided with a pulley 324 corresponding to the guide groove, which is in contact with the side of the rack away from the gear.
[0065] In this embodiment, the rack is driven to move linearly by the first power device, which in turn drives the gear to rotate, thereby realizing the rotation of the stop rod. When the rack moves, the guide groove of the guide block and the pulley work together to constrain the linear motion trajectory of the rack, which can improve the motion accuracy of the rack. At the same time, the rolling contact between the pulley and the rack reduces the motion friction of the rack.
[0066] In addition, the first power unit may also be a rotary drive device, such as a motor, rotary cylinder, rotary hydraulic cylinder, etc., which is directly coaxially connected to the stop bar to drive the stop bar to rotate.
[0067] In this embodiment, as Figure 1 As shown, the injection device also includes a lifting mechanism, which drives the material blocking mechanism to move vertically.
[0068] like Figure 8 As shown, the lifting mechanism includes:
[0069] Second power unit 510;
[0070] The lifting mechanism 520 is connected to the second power device, and the material blocking mechanism is installed on the lifting mechanism.
[0071] For example, such as Figure 9 As shown, the lifting mechanism includes:
[0072] Eccentric wheel 521 is driven to rotate eccentrically by a second power device;
[0073] Crank 522, one end of which is fitted onto the outside of the eccentric wheel;
[0074] Carriage 524, which is connected to the end of the crank away from the eccentric wheel, and the material stop mechanism is mounted on the carriage.
[0075] For example, the lifting mechanism further includes a fixing part 523, on which the second power device is fixedly installed; the bottom of the slide is provided with a second guide rod 526, which slides in cooperation with the fixing part.
[0076] In this embodiment, the second power device can be a rotating power device such as a motor, a rotary cylinder, or a rotary hydraulic cylinder. The second power device drives the eccentric wheel 521 to generate eccentric rotation, which is then transmitted through the crank 522 to the vertical linear motion of the slide 524. This adjusts the distance between the material blocking mechanism and the conveyor belt, thus adapting to containers of different heights. At the same time, the sliding constraint between the second guide rod and the fixed part improves the motion accuracy of the material blocking mechanism.
[0077] In this embodiment, the lifting motion mechanism can be provided in two sets. The two sets of lifting motion mechanisms are respectively connected to both ends of the blocking mechanism. The two sets of lifting motion mechanisms are connected by a connecting shaft to realize power transmission, that is, the eccentric wheels of the two sets of lifting motion mechanisms are connected by the connecting shaft.
[0078] In addition, the filling device may also include a frame 600, on which the fixing part is fixedly installed. Furthermore, a first guide rod 525 fixedly connected to the material blocking mechanism is provided on the top of the slide, and the first guide rod slides relative to the frame. In addition, a conveyor belt 100 is fixedly installed on the frame below the material blocking mechanism.
[0079] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
