Description

Technical Field

[0001] The utility model belongs to the technical field of food processing, and particularly relates to a bar stock feeding device for processing rod-shaped food. Background Art

[0002] Gluten skewers are common rod-shaped barbecue snacks on the market at present. To enhance the taste of the snacks during barbecue, such foods usually need to be stringed through the center, and regular cut openings and elongation are formed on the food.

[0003] Currently, the processing of gluten skewers mainly adopts a processing method mainly by manual labor and mechanical assistance, which has problems of low processing efficiency and poor product quality.

[0004] To solve the problems of high-efficiency and high-quality processing of rod-shaped foods such as gluten skewers, with the application number: 202410623372.3 and the name: An integrated processing equipment for stringing, cutting and stretching rod-shaped foods, a fully automatic processing equipment for rod-shaped foods is designed, which mainly includes a frame 1, a skewer feeding mechanism 4, a feeding mechanism, an integrated feeding and material length detection mechanism 9, a cutting and stretching integrated mechanism 5, a finished product output mechanism 8 and a control system 3. See Figure 1 Among them, the feeding mechanism is used to convey bar stocks one by one to a position aligned with the front end of the processing center of the cutting and stretching integrated mechanism at a set production speed. The integrated feeding and material length detection mechanism is used to receive the bar stocks output by the feeding mechanism, detect the material length and push them to the cutting and stretching center position after detection. See Figure 2 Among them, the feeding mechanism is composed of a front-end feeding mechanism 7, a middle material conveying mechanism 6 and a rear-end feeding mechanism 2. Both the front-end feeding mechanism and the rear-end feeding mechanism adopt a stepped feeding mechanism 2.2 composed of a fixed guide plate and movable guide plates set at intervals, and the stepped feeding mechanism at the rear end is placed in a large material bin 2.1. The middle material conveying mechanism adopts a single-belt conveying mechanism. The integrated feeding and material length detection mechanism mainly consists of a receiving trough, a feeding mechanism and a material length detection unit. The receiving trough is connected to the movable push plate at the end of the front-end feeding mechanism to realize the connection between the feeding mechanism and the integrated feeding and material length detection mechanism.

[0005] For this integrated processing equipment, when the prototype is running, it can achieve relatively high production efficiency and product qualification rate. Among them, when the feeding mechanism is actually used, there are problems such as slightly complex structure, easy accumulation of material residues at the front end and difficult to clean. In addition, the feeding speeds of the front-end feeding mechanism and the rear-end feeding mechanism need to be matched to avoid the problem of material stacking during the transportation of bar stocks.

[0031] The structure of the utility model will be further described below with reference to the drawings and through embodiments. It should be noted that this embodiment is narrative rather than restrictive.

[0032] A rod material feeding device for processing rod-shaped food, please refer to Figures 3 - 8 , and its invention is: including a starting-end feeding mechanism 10, an intermediate material distributing and conveying mechanism 11 and a terminal feeding mechanism 12.

[0033] The starting-end feeding mechanism uses a stepped feeding method for feeding, mainly including a storage bin 10.1 and a stepped feeding mechanism 10.2 provided on one side of the storage bin. The storage bin is used to temporarily store a large number of bar materials, and the stepped feeding mechanism realizes the upward feeding of bar materials row by row. The stepped feeding mechanism mainly includes a plurality of fixed guide plates, a plurality of movable pusher plates, and a pusher plate driving mechanism. The plurality of fixed guide plates are arranged in sequence along the slope direction at the same inclination angle and at a set interval, and are fixed on one side of the storage bin. A movable pusher plate is slidably installed between every two adjacent fixed guide plates, and the upper end of the movable pusher plate is the acting end for pushing the materials upward. The lower ends of the plurality of movable pusher plates are commonly connected to an acting plate. The acting plate is drivingly connected to the pusher plate driving mechanism. The pusher plate driving mechanism consists of a feeding driving rack, a feeding driving gear, and a feeding servo motor (not shown in the drawings). The feeding driving rack is fixedly parallel to the acting plate and meshes with the feeding driving gear. The feeding driving gear is fixedly supported on a gear shaft, the gear shaft is fixed on the machine frame, and one end of the gear shaft is drivingly connected to the feeding servo motor. By the forward rotation of the feeding servo motor, a plurality of movable pusher plates can be driven to synchronously move upward along the slope direction. During the upward movement, the bar materials are pushed to the upper step, realizing the upward feeding of bar materials step by step. When the feeding servo motor rotates in reverse and the movable pusher plate moves to the lower working position, the bar materials of the next step are received. This starting-end feeding mechanism has been recorded in the application number: 202410623372.3, and the name: an integrated processing equipment for skewering, cutting, and spreading of compact rod-shaped foods, which is not the innovation point of the present utility model.

[0034] The innovation point of the present utility model is: the modified design of the intermediate material distribution and conveying mechanism and the end feeding mechanism.

[0035] Intermediate material distribution and conveying mechanism

[0036] The whole adopts a belt conveyor mechanism, including a frame, a front-end high-speed belt conveyor mechanism 11.1, a rear-end low-speed belt conveyor mechanism 11.3 and a differential drive mechanism 11.2. The front-end high-speed belt conveyor mechanism and the rear-end low-speed belt conveyor mechanism are arranged in a front-to-back connection and are both installed on the frame. The rear end of the rear-end low-speed belt conveyor mechanism is arranged outside and above the uppermost movable pusher plate of the starting-end feeding mechanism for receiving the bar stock output by the starting-end feeding mechanism. The differential drive mechanism is installed outside the frame and is jointly drivingly connected to the rear drive shaft of the front-end high-speed belt conveyor mechanism and the front drive shaft of the rear-end belt conveyor mechanism. The differential drive mechanism includes a belt drive motor 11.2.1, a driving gear 11.2.2, a first driven gear 11.2.3 and a second driven gear 11.2.4. The belt drive motor is installed on the motor bracket, and the motor bracket is fixedly connected to the frame. The driving gear is fixedly connected to the output end of the belt drive motor. The first driven gear and the second driven gear are both meshed with the driving gear. The outer diameter of the first driven gear is smaller than that of the second driven gear. The first driven gear is fixed to the end of the rear drive shaft of the front-end high-speed belt conveyor mechanism, and the second driven gear is fixed to the end of the front drive shaft of the rear-end belt conveyor mechanism, so as to transmit power to the front conveyor belt and the rear conveyor belt and realize the fast operation of the front conveyor belt and the slow operation of the rear conveyor belt. By adopting the bar stock conveying method of fast at the front and slow at the rear, the bar stocks can be evenly separated during the conveying process, and the problem of overlapping materials caused by improper front and rear speed adjustment can be avoided.

[0037] The above-mentioned front-end high-speed belt conveyor mechanism and rear-end low-speed belt conveyor mechanism can be arranged at the same height or at different heights. In the present utility model, the height of the upper travel section of the conveyor belt of the front-end high-speed belt conveyor mechanism is slightly higher than that of the upper travel section of the conveyor belt of the rear-end low-speed belt conveyor mechanism. In this way, when the bar stock is conveyed from the end of the front conveyor belt to the starting end of the rear conveyor belt, better material separation can be achieved through the existence of climbing and speed difference.

[0038] End feeding mechanism

[0039] It includes a material-in-place detection mechanism 12.2, a material pushing-out mechanism 12.1, a material receiving groove 12.5 and a material conveying-in-place mechanism 12.3.

[0040] The material-in-place detection mechanism is used to detect the position of the bar stock conveyed to the front end of the front conveyor belt. The material pushing-out mechanism is used to push the bar stock conveyed to the front position on the front conveyor belt into the material receiving groove. The material conveying-in-place mechanism is used to push the material receiving groove and the bar stock in the material receiving groove to a set position. At this station, in cooperation with the integrated feeding and material length detection mechanism of the processing equipment, the bar stock is pushed to the cutting and unfolding center position of the cutting and unfolding integrated mechanism.

[0041] The material arrival detection mechanism includes a fixed vertical plate 12.2.1, a detection plate 12.2.2, and a proximity sensor (not shown in the drawings). The fixed vertical plate is fixed outside the front end of the conveyor belt of the front-end high-speed belt conveyor mechanism through an extended bracket, and an installation groove is provided at the upper end of the fixed vertical plate. The detection plate is an angle plate with an arc transition, and the detection plate is installed in the installation groove in a swingable manner through a transition position. The proximity sensor is fixed on the inner side of one side of the fixed vertical plate close to the front conveyor belt. When the bar stock is conveyed to the position of the detection plate, with the operation of the conveyor belt, the bar stock pushes the detection plate to swing around the installation groove, making the detection plate close to the proximity sensor. After the proximity sensor senses the detection plate, it transmits a signal to the control system to control the movement of the material pushing mechanism, so as to push the frontmost bar stock into the receiving chute.

[0042] The material pushing mechanism includes a pushing cylinder 12.1.1, a pushing vertical plate 12.1.2, and a pushing roller 12.1.3. The pushing cylinder is installed at the lower end of the support plate 12.4, and the support plate is fixedly installed above the conveyor belt at the front end of the high-speed belt conveyor mechanism on the frame. The pushing vertical plate is fixedly installed at the rod end of the pushing cylinder and is close to one side of the receiving chute. A groove is provided at the lower end of the pushing vertical plate, and a roller shaft is fixedly installed in the groove. The axial direction of the roller shaft is consistent with the conveying direction of the bar stock, and the pushing roller is rotatably installed on the roller shaft. By using this material pushing mechanism, an upward and sideward pushing force towards the receiving chute is applied to the bar stock through the pushing roller, so as to smoothly push the bar stock into the receiving chute. Compared with direct plate pushing, it can better avoid the bar stock being squeezed and deformed. In addition, an outwardly inclined baffle plate is provided on the frame on the outside of the front conveyor belt close to the receiving chute. Preferably, the height of the baffle plate is lower than the radius of the bar stock. The function of the baffle plate is to prevent the bar stock from slipping by itself after being conveyed to this position without the action of the material pushing mechanism, so that the receiving chute cannot receive the material smoothly. In addition, it plays a guiding role during the lateral material pushing process.

[0043] The receiving chute adopts a trough structure with an opening at the upper end and a V-shaped cavity at the lower end, and a rectangular guide groove along the bar is provided at the lower end of the V-shaped cavity for the installation and guidance of the feeding mechanism of the whole machine. The feeding mechanism is composed of a feeding guide plate 9.3, a motor 9.1 for driving the feeding guide plate, and a gear and rack 9.2 mechanism to realize backward feeding. For the feeding mechanism and the material length detection mechanism, refer to Figure 1 and 2 the prior applications in

[0044] The rod feeding-in-place mechanism includes slide rails 12.3.4, slide rail guide seats 12.3.5, a feeding motor 12.3.1, a feeding gear 12.3.2, and a feeding rack 12.3.3. Two slide rail supports are fixedly installed at the upper end of the support plate in alignment in the left-right direction. The slide rails are in guiding cooperation with the guiding grooves on the two slide rail guide seats in a slidable manner in the left-right direction. The feeding rack is fixed to the upper end of the slide rails in the left-right direction. The feeding motor is fixed to the support plate, and the lower output end of the feeding motor is fixedly connected to the feeding gear. The feeding gear meshes with the feeding rack. The receiving chute is fixedly suspended at the lower left end of the feeding slide rail through a chute support. When the above-mentioned feeding motor operates, through the meshing of the feeding gear and the feeding rack, the slide rails are driven to move leftward. The slide rails drive the receiving chute and the rod in the receiving chute to move leftward synchronously. When the slide rails move to the set position at the left end (the moving amount can be controlled by a program or the position can be detected by setting sensors), the rod is pushed to the set position, and this position is aligned with the cutting and unfolding center position of the whole machine in the front-back direction.

[0045] The working principle of the rod feeding device for processing rod-shaped food is as follows:

[0046] The rods temporarily stored in the starting-end feeding mechanism are pushed row by row upward to the conveyor belt of the rear-end low-speed belt conveying mechanism under the reciprocating operation of the stepped feeding mechanism. As the conveyor belt runs forward, when the rods are conveyed to the conveyor belt of the front-end high-speed belt conveying mechanism, the rods are evenly separated in the front-back direction; when the rods are conveyed to the front position of the front conveyor belt, the proximity sensor of the material-in-place detection mechanism detects the signal that the rods are conveyed in place. The control system starts the pushing air cylinder according to this control signal. The pushing air cylinder pushes the rods horizontally through the pushing rollers, so that the rods cross the baffle and smoothly slide into the receiving chute. At this time, the receiving chute is located at the working station close to the intermediate material distribution and conveying mechanism; the pushing mechanism starts to push the rods backward, so that the rear end of the rods contacts the lower end of the elastic sheet 9.4 of the rod length detection mechanism arranged at the rear of the receiving chute. Since the upper end of the elastic sheet is fixed to the side frame plate, the elastic sheet swings backward and is detected by the proximity switch 9.5 fixed to the side frame plate, realizing the detection of the rod length; after the rod length detection is completed; the feeding motor starts, and drives the slide rails to drive the receiving chute to move towards the set position through the meshing structure of the gear and the rack. After moving in place, it stops. The in-place position is located at the position aligned with the cutting and unfolding center of the whole machine. Subsequently, the rod length detection and the pushing of the rods backward to the cutting and unfolding center position can be completed through the integrated feeding and rod length detection mechanism of the whole machine, realizing smooth feeding.

[0047] Although embodiments and drawings of the present utility model are disclosed for illustrative purposes, those skilled in the art can understand that various substitutions, changes, and modifications are possible without departing from the spirit of the present utility model and the appended claims. Therefore, the scope of the present utility model is not limited to the content disclosed in the embodiments and drawings.
