Description

Technical Field

[0001] The invention belongs to the technical field of unsealing food raw material packaging bags, and in particular relates to a food raw material unsealing and feeding device. Background Art

[0002] When preparing seasonings or cooking dishes in large woks, a large number of seasoning ingredients are required, including various sauces such as broad bean paste, soybean paste, and chili sauce. To reduce costs and increase feeding speed, these ingredients are often packaged in barrels, which include plastic bags for the sauces themselves and plastic outer barrels for the bags. Because large woks are typically at least 1.5 meters above the ground, the current feeding process involves manually removing the plastic bags from the barrels and then lifting them above the wok to feed the ingredients, or by workers standing next to the wok on a high stool. Both methods require workers to be close to the wok to feed the ingredients, which presents the following drawbacks: First, the wok's surrounding area is hot during the cooking process, with high-temperature steam rising from above, posing a risk of burns to the worker; second, the close proximity of the worker to feed the ingredients can cause oil in the wok to splash, also posing a safety hazard; third, the large number of ingredients and the long hours involved can easily lead to worker fatigue, further increasing the risk of accidents. Summary of the Invention

[0003] In order to solve the deficiencies of the prior art, the present invention provides a food raw material unsealing and feeding device, which can realize automatic unsealing and extrusion discharging, has higher safety, and can reduce the difficulty of feeding.

[0004] In order to achieve the purpose of the present invention, the following scheme is proposed:

[0005] A food raw material unsealing and feeding device comprises a column, a material guiding tube, an extrusion component and a clamping head.

[0006] The top of the column is rotated to provide a cantilever in a horizontal state;

[0007] The material guide pipe is arranged at the rear end of the cantilever, the upper and lower ends of the material guide pipe are connected, the bottom surface of the material guide pipe is higher than the top of the frying pan, and the lower end of the inner wall of the material guide pipe is provided with a blade;

[0008] The extrusion assembly includes a gantry and extrusion plates symmetrically arranged on opposite sides of the guide tube. The extrusion plates are rotated inside the guide tube by a rotating rod. The front end of the extrusion plate faces the middle of the guide tube. The rear end of the extrusion plate is provided with an extension rod, which extends to the outside of the guide tube. The crossbeam of the gantry is arranged parallel to the middle of the upper part of the guide tube. The two side rods of the gantry face vertically downward and are both located on the outside of the guide tube. The lower ends of the side rods are connected to the extension rods. The gantry is arranged to move in the vertical direction relative to the guide tube to drive the extrusion plates to swing around the rotating rod.

[0009] The chuck is arranged to move in the vertical direction, and its projection on the horizontal plane is located inside the material guide tube. The chuck is located below the crossbeam, and an elastic member that stretches vertically is provided between the top of the chuck and the crossbeam. The chuck is used to clamp the plastic bag.

[0010] The beneficial effects of the present invention are:

[0011] 1. This solution uses a cantilever to move the plastic bag containing the raw materials above the wok, keeping the workers away from the wok and avoiding the safety hazards caused by high temperature and oil splashing to the workers;

[0012] 2. The feeding process can automatically open and squeeze the plastic bags, reducing manual intervention and effectively preventing raw material residue. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] like Figures 1 to 5As shown, a food raw material unsealing and feeding device includes: a column 1, a material guide tube 3, an extrusion component 4 and a clamp 5.

[0022] The top of the column 1 is rotatably provided with a horizontal cantilever 2, which can be rotated by manual pushing or by motor-driven rotation. The column 1 is a telescopic rod structure, and the height of the cantilever 2 can be adjusted to accommodate frying pans of different heights.

[0023] The material guide tube 3 is arranged at the rear end of the cantilever 2. The upper and lower ends of the material guide tube 3 are connected, and its bottom surface is higher than the top of the wok. A blade 31 is provided at the lower end of the inner wall of the material guide tube 3. As a preferred structure, the tip of the blade 31 faces the middle of the material guide tube 3, and the blade 31 is vertically arranged on one of the inner walls of the material guide tube 3.

[0024] The extrusion assembly 4 includes a gantry 41 and extrusion plates 42 symmetrically arranged on opposite sides of the guide tube 3. The extrusion plates 42 are rotatably arranged inside the guide tube 3 through a rotating rod 421. The front end of the extrusion plate 42 faces the middle of the guide tube 3, and the rear end of the extrusion plate 42 is provided with an extension rod 422. The extension rod 422 extends to the outside of the guide tube 3. Specifically, the guide tube 3 is provided with a vertical avoidance hole at the position where the extension rod 422 passes. When the extrusion plate 42 swings around the rotating rod 421, the avoidance hole is used to provide movement space for the extension rod 422. The crossbeam 411 of the gantry 41 is arranged in parallel in the middle above the guide tube 3. The two side rods 412 of the gantry 41 are vertically downward and are both located on the outside of the guide tube 3. The lower ends of the side rods 412 are connected to the extension rod 422. The gantry 41 is arranged to move in the vertical direction relative to the guide tube 3 to drive the extrusion plate 42 to swing around the rotating rod 421.

[0025] The chuck 5 is arranged to move in the vertical direction, and its projection on the horizontal plane is located inside the material guide tube 3. Specifically, the chuck 5 can be raised and lowered by a cylinder or a traction device. The chuck 5 is located below the beam 411, and an elastic member 51 that is retractable in the vertical direction is provided between the top of the chuck 5 and the beam 411. The chuck 5 is used to clamp the plastic bag.

[0026] Typically, the column 1 is fixed on one side of the wok, such as Figure 4 As shown, in the initial state, the gantry 41 is at the lowest position, so the lower end of the side rod 412 and the extension rod 422 connected to the side rod 412 are also at the lowest position. Therefore, the front end of the extrusion plate 42 is set upward and close to the side wall of the guide tube 3. At this time, there is a maximum gap between the front ends of the two extrusion plates 42. This state facilitates the passage of the chuck 5. The use process mainly includes the following steps:

[0027] The first step is to place the plastic bucket containing the raw materials on the side of the column 1 away from the wok, and manually open the top cover of the plastic bucket;

[0028] Step 2: Lower the chuck 5 and use the chuck 5 to clamp the top of the plastic bag, then move the chuck 5 upward so that the bottom of the plastic bag is higher than the top of the frying pan;

[0029] Step 3: Rotate the cantilever 2 to move the plastic bag to the top of the wok. As a preferred solution, the cantilever 2 can be set to a suitable length so that the plastic bag can be moved to the middle position above the wok to reduce the probability of oil splashing outside the wok when adding materials.

[0030] Step 4: Move the chuck 5 upwards, thereby carrying the plastic bag into the material guide tube 3. After the plastic bag enters the material guide tube 3, the blade 31 will cut the plastic bag, thereby achieving the purpose of unsealing. The raw materials can flow out from the cut hole in the plastic bag and automatically discharged into the wok;

[0031] Step 5: Continue to move the chuck 5 upwards, so that the chuck 5 passes through the gap between the front ends of the two extrusion plates 42, until the two ends of the elastic member 51 begin to be stressed. Because the elastic member 51 is arranged between the crossbeam 411 and the chuck 5, the force exerted on the elastic member 51 is a compressive force. When the elastic member 51 is stressed, it will generate an upward supporting force on the crossbeam 411, thereby driving the entire gantry 41 to move upward. When the gantry 41 moves upward, it will drive the extension rod 422 to swing upward through the side rod 412, and the extrusion plate 42 will swing downward around the rotating rod 421. When the extrusion plate 42 swings downward, it will squeeze the outside of the opposite sides of the plastic bag, thereby pressurizing the raw materials inside the plastic bag to the middle and bottom, so as to speed up the discharge of the raw materials; because the force of the gantry 41 rising The force originates from the chuck 5 but is ultimately applied to the gantry 41 through the elastic member 51. Therefore, the swinging torque generated by the gantry 41 on the extrusion plate 42 is not a rigid force, but a gentle swinging torque transmitted through the elastic member 51. This allows the extrusion plate 42 to squeeze the plastic bag more gently, preventing the rigid extrusion force from causing the plastic bag to burst. On the other hand, because the elastic member 51 is provided between the crossbeam 411 and the chuck 5, even if the gantry 41 cannot continue to rise and the extrusion plate 42 cannot continue to swing, the compression of the elastic member 51 can still be used to meet the chuck 5's need for rising space, so that the bottom of the plastic bag is as close to the extrusion plate 42 as possible, so that the material in the plastic bag can be squeezed out more thoroughly by the extrusion plate 42, reducing the residual material in the plastic bag.

[0032] After the feeding is completed, the guide tube 3 is moved to the outside of the wok, and then the chuck 5 is lowered. When the crossbeam 411 loses the support of the elastic member 51, the gantry 41 will automatically fall under the action of gravity, and drive the extrusion plate 42 to swing upward and toward the side of the guide tube 3, thereby making room for the chuck 5 to descend. When the chuck 5 drops to the bottom of the guide tube 3, the worker can take away the plastic bag.

[0033] The entire feeding process of this solution does not require workers to get close to the wok, avoiding the safety hazards caused by high temperature and splashing oil to workers, and can effectively reduce the labor intensity of workers; the feeding process realizes the functions of automatic unsealing, automatic blanking and automatic extrusion discharge, with a higher degree of automation, and the discharge is clean and thorough.

[0034] Preferably, Figure 2 、 Figure 4 As shown, blades 31 are vertically provided on one set of opposite inner walls of the guide tube 3, and the tips of the two blades 31 are opposite to each other. The blades 31 are located between the two extrusion plates 42. This solution can not only unseal both sides of the plastic bag at the same time and increase the discharge speed, but also prevent the extrusion plates 42 from directly contacting the unsealed discharge port, which can effectively reduce or even prevent the residue of raw materials on the extrusion plates 42.

[0035] As a preferred structure, when the material guiding tube 3 is a rectangular tube structure, the blade 31 and the extrusion plate 42 are arranged on two adjacent inner walls.

[0036] Preferably, Figure 2 、 Figure 4 and Figure 5 As shown, the extension rod 422 is provided with a strip hole 423 along the length direction, and the opening of the strip hole 423 is set in the horizontal direction. The lower end of the side rod 412 is passed through the strip hole 423 through a pin shaft. When the side rod 412 moves in the vertical direction and drives the extension rod 422 to swing, the pin shaft will move in the strip hole 423 to adapt to the change in the angle of the extension rod 422.

[0037] Specifically, the material guide tube 3 can be connected to the end surface of the rear end of the cantilever 2 by screws, so that the material guide tube 3 is connected to the cantilever 2 in a suspended state. As another preferred solution, Figure 1 、 Figure 4 and Figure 5 As shown, the material guide tube 3 is arranged at the bottom of the rear end of the cantilever 2, and a through hole aligned with the material guide tube 3 is opened in the vertical direction at the rear end of the cantilever 2. The gantry 41 is erected on the cantilever 2, the crossbeam 411 is located above the cantilever 2, and the side rods 412 are respectively located on both sides of the rear end of the cantilever 2. Compared with the suspended installation structure, this solution can effectively improve the installation stability of the material guide tube 3.

[0038] As a further preference, screws passing through the side rods 412 are provided on both sides of the rear end of the cantilever 2, and the holes on the side rods 412 for passing the screws are longitudinally arranged long strips to accommodate the lifting and lowering of the gantry 41. Through this structural design, the stability of the installation position of the gantry 41 and the smoothness during movement can be improved, preventing the gantry 41 from swinging.

[0039] Preferably, Figure 1 、 Figure 2and Figure 4 、 Figure 5 As shown, the cantilever 2 is provided with a traction system, which includes a traction rope 61 and a drive assembly. The end of the traction rope 61 is used to connect to the clamp 5, and the drive assembly controls the lifting and lowering of the clamp 5 through the traction rope 61. Preferably, the drive assembly is provided at the front end of the cantilever 2, and the front end and rear end of the cantilever 2 are respectively located on both sides of the column 1 to maintain the balance of the cantilever 2.

[0040] More specifically, the drive assembly includes a motor 62 and a winch 63 for winding the traction rope 61. The winch 63 is arranged at the front end of the cantilever 2. A worm gear is coaxially provided on the winch 63. The front end of the cantilever 2 is provided with a worm gear meshing with the worm gear. The worm gear is connected to the main shaft of the motor 62 by a belt drive, and the outer diameter of the pulley set on the main shaft of the motor 62 is larger than the outer diameter of the pulley set on the worm gear. This scheme uses a worm gear transmission to drive the winch 63 to rotate, so as to achieve the retraction or release of the traction rope 61, and at the same time achieve the purpose of locking the winch 63 to prevent the chuck 5 from falling suddenly, and then increase the rotation speed of the worm gear by rotating the belt with a large transmission ratio to ensure that the worm gear and the winch 63 obtain sufficient rotation speed.

[0041] Preferably, Figures 3 to 5As shown, the chuck 5 includes a circular ring 52 and a connecting disk 53. The circular ring 52 is provided with a plurality of claws 54 in a circular array. The middle section of the claw 54 is rotatably connected to the circular ring 52, and the axis of rotation is consistent with the tangent direction of the circular ring 52. The inner end of the claw 54 is located on the inner side of the circular ring 52. The length of the claw 54 protruding from the inside of the circular ring 52 is greater than the radius of the inner hole of the circular ring 52. Normally, the inner end of the claw 54 is inclined toward the upper side of the axis of the circular ring 52, and the outer end of the claw 54 is located on the outer side of the circular ring 52. The outer ends of the claws 54 are respectively rotatably connected to the lower end of a hinged rod 55, and the upper end of the hinged rod 55 is rotatably connected to the connecting disk 53. The elastic member 51 is located above the connecting disk 53; this structure can control the inner ends of all the claws 54 to simultaneously retract toward the center of the circular ring 52 or open toward the side of the circular ring 52 by relative movement of the circular ring 52 and the connecting disk 53. When clamping the plastic bag, the worker closes the bag mouth of the plastic bag and moves the ring 52 toward the connecting disk 53, thereby opening the inner end of the clamping claw 54 and inserting the closed plastic bag from the bottom of the ring 52 so that the plastic bag is higher than the inner end of the clamping claw 54; then the ring 52 is manually moved downward, and the inner end of the clamping claw 54 will simultaneously be retracted toward the middle of the ring 52, and the plastic bag is preliminarily compressed, and then the chuck 5 is raised. In the specific implementation, the cylinder or the traction device is used to directly drive the connecting disk 53 to rise. In this embodiment, the traction rope 61 is connected to the connecting disk 53 and drives the connecting disk 53 to rise. At this time, the friction between the plastic bag and the inner end of the clamping claw 54 will further drive the inner end of the clamping claw 54 to swing downward to increase The clamping force between the claws 54 and the plastic bag, when the plastic bag is completely separated from the ground, the weight of the raw materials inside the plastic bag is completely borne on the claws 54, and the gravity also increases the downward pressure of the inner end of the claws 54, so that the claws 54 press the plastic bag tighter; after the feeding is completed, it is only necessary to move the ring 52 upward to make all the claws 54 release the plastic bag at the same time. This solution can achieve the purpose of quickly clamping and releasing the plastic bag, and has a stable clamping effect. When the extrusion plate 42 squeezes the plastic bag, it will increase the resistance of the plastic bag to move toward each other, and this resistance will also be transferred to the claws 54, further increasing the clamping force of the inner end of the claws 54 on the plastic bag, effectively preventing the plastic bag from slipping during the extrusion process.

[0042] Preferably, Figure 3 As shown, a weight is provided at the outer end of the claw 54 so that when the ring 52 is moved upward, the rear end of the claw 54 automatically swings downward, thereby automatically opening the inner end of the claw 54; preferably, an anti-slip groove is provided on the inner end face of the claw 54 to increase the friction between the claw 54 and the plastic bag and improve the clamping stability of the plastic bag.

[0043] Preferably, the column 1 is arranged on a movable chassis to facilitate transfer to different woks for loading.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to be the only one or to limit the present invention. It should be understood by those skilled in the art that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
