Description

Technical fields:

[0001] This utility model relates to the field of food processing equipment technology, and more specifically to a food drum mixer. Background technology:

[0002] With the rapid economic development, the food industry has transformed from a traditional labor-intensive industry to a technology-intensive industry, and various food processing machines have emerged. For some foods, such as those that require thorough mixing of seasonings, like some pickles and lobsters, the seasonings need to be evenly distributed on the ingredients. These foods need to be thoroughly mixed to achieve the desired flavor. People usually use drum mixers to mix food.

[0003] Existing drum mixers typically place the drum on top of the frame, with support wheels mounted on support shafts on both sides of the frame supporting the drum. A drive gear on the support shafts drives a gear ring fixed on the outer wall of the drum's center to rotate, thus rotating the drum. The drum's own weight allows it to rotate smoothly on the support wheels. However, its rotation speed is limited. Excessive rotation speed may cause the drum to detach from the frame, and there is also a risk that an external object may knock the drum off, affecting its normal operation. Utility model content:

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a food drum mixer. Its mixing drum is limited by a limiting sleeve, which enables it to operate normally even when the rotation speed is increased, and it will not fall out when hit by external objects, thus ensuring its normal operation.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] A food drum mixer includes a frame and a mixing drum. The mixing drum is mounted on the frame. A rear vertical frame is fixed to the rear part of the frame. A feed hopper is fixed to the top of the rear vertical frame. The front end of the feed hopper extends into the rear feed inlet of the mixing drum. Bearing seats are fixed to the left and right parts of the front and rear parts of the top of the frame. A drive shaft is fixed to the inner ring of the bearing inside the corresponding two bearing seats. A drive gear is fixed to the middle of one of the drive shafts. An external gear ring is fixed to the outer wall of the middle part of the mixing drum. The external gear ring meshes with the drive gear.

[0007] Guide wheels are fixed at the front and rear of the two drive shafts, and the outer side walls of the guide wheels rest against the corresponding outer side walls at the lower part of the left and right sides of the stirring cylinder.

[0008] A stirring drive motor is fixed on the top surface of one side of the rear frame of the machine frame, and the output shaft of the stirring drive motor is connected to the rear end of the corresponding transmission shaft.

[0009] A limiting sleeve is fitted around the middle part of the mixing cylinder. Vertical support plates extending downward are formed on the left and right sides of the limiting sleeve. The bottom of the vertical support plates is fixedly connected to the top surface of the left or right side of the frame by bolts.

[0010] An upper buffer frame is installed on the top plate of the limiting sleeve, and an upper limit wheel installed on the lower part of the upper buffer frame presses against the top surface of the middle part of the mixing cylinder.

[0011] The upper buffer frame includes a horizontal fixed plate, with end plates fixed to the front and rear bottom surfaces of the horizontal fixed plate. The two ends of the hinge shaft movably connected to the middle of the upper limit wheel are fixed to the end plates. Two vertical guide rods are fixed to the top surface of the horizontal fixed plate, and the vertical guide rods are inserted into the corresponding through holes formed on the top plate of the limiting sleeve.

[0012] The lower part of the vertical guide rod is fitted with a buffer spring. The top end of the buffer spring is attached to the bottom surface of the top plate of the limiting sleeve, and the bottom end of the buffer spring is attached to the top surface of the horizontal fixing plate.

[0013] The two upper buffer frames are located at the front and rear of the upper part of the outer gear ring.

[0014] The inner walls of the front and rear ends of the limiting sleeve are formed with radially extending bent edges. The upper part and left and right sides of the bent edges of the front and rear ends are formed with through-holes. The screw part of the limiting adjustment bolt is screwed into the corresponding through-hole. The inner end of the screw part of the limiting adjustment bolt extends out of the inner end of the corresponding through-hole and is movably connected to the limiting plate. A self-lubricating plate is fixed on the rear wall of the front limiting plate. The rear end face of the self-lubricating plate is close to the front end face of the front annular guide part. A self-lubricating plate is fixed on the front wall of the rear limiting plate. The front end face of the self-lubricating plate is close to the rear end face of the rear annular guide part.

[0015] A compression spring is inserted into the screw portion of the limiting adjustment bolt. One end of the compression spring applies force to the inner end face of the corresponding bent edge, and the other end applies force to the corresponding end face of the corresponding limiting plate.

[0016] The outstanding effect of this utility model is:

[0017] Its mixing cylinder is limited by a limiting sleeve, which allows it to operate normally even when the rotation speed is increased, and it will not fall out when hit by external objects, thus ensuring its normal operation. Attached image description:

[0021] Figure 4 yes Figure 1 A magnified view of another part;

[0022] Figure 5 This is a partial top view of the machine frame. Detailed implementation method:

[0023] For example, see below. Figures 1 to 5 As shown, a food drum mixer includes a frame 10, a mixing drum 20 mounted on the frame 10, a rear vertical frame 30 fixed on the rear frame of the frame 10, and a feed hopper 40 fixed on the top of the rear vertical frame 30. The front end of the feed hopper 40 extends into the rear feed inlet of the mixing drum 20. The structures of the feed hopper 40 and the mixing drum 20 in this embodiment are conventional existing structures, which will not be described in detail here. The attached figure is a simplified illustration.

[0024] Furthermore, bearing seats 11 are fixed at the front and rear left and right sides of the top of the frame 10, and the transmission shaft 12 is fixed on the inner ring of the bearing inside the corresponding two bearing seats 11. A drive gear 13 is fixed in the middle of one of the transmission shafts 12, and an external gear ring 21 is fixed on the outer wall of the middle part of the stirring cylinder 20. The external gear ring 21 meshes with the drive gear 13.

[0025] Guide wheels 14 are fixed at the front and rear of the two drive shafts 12, and the outer side wall of the guide wheel 14 rests against the outer side wall of the lower part of the left and right sides of the stirring cylinder 20.

[0026] Annular guide portions 22 are fixed on the outer side walls of the front and rear parts of the middle section of the stirring cylinder 20. An annular groove is formed in the middle of the outer side wall of the guide wheel 14. The corresponding part of the annular guide portion 22 is inserted into the corresponding annular groove and cooperates with it.

[0027] This structure restricts the front and rear positions of the stirring cylinder 20 by the guide wheel 14. The guide wheel 14 is a nylon guide wheel.

[0028] There is a gap between the front and rear inner walls of the annular groove and the front and rear walls of the corresponding annular guide 22.

[0029] The middle part of the mixing cylinder 20 is fitted with a limiting sleeve 50. The limiting sleeve 50 is an arc-shaped upper plate with vertical support plates 51 extending downward on the left and right sides. The bottom of the vertical support plates 51 is fixedly connected to the top surface of the left or right side of the frame 10 by bolts.

[0030] Furthermore, the inner walls of the front and rear ends of the limiting sleeve 50 are formed with radially extending bent edges 52. The upper part and left and right sides of the bent edges 52 at the front and rear ends are each formed with through-holes. The screw portion of the limiting adjusting bolt 53 is screwed into the corresponding through-hole. The inner end of the screw portion of the limiting adjusting bolt 53 extends out of the inner end of the corresponding through-hole and is movably connected to the limiting plate 54. A self-lubricating plate 55 is fixed to the rear wall of the front limiting plate 54, with the rear end face of the self-lubricating plate 55 close to the front end face of the annular guide portion 22. A self-lubricating plate 55 is fixed to the front wall of the rear limiting plate 54, with the front end face of the self-lubricating plate 55 close to the rear end face of the annular guide portion 22. The self-lubricating plate 55 is a nylon plate.

[0031] A compression spring 56 is inserted into the screw portion of the limiting adjustment bolt 53. One end of the compression spring 56 is applied to the inner end face of the corresponding bent edge 52, and the other end is applied to the corresponding end face of the corresponding limiting plate 54.

[0032] This structure can change the distance between the corresponding end face of the self-lubricating plate 55 and the corresponding end face of the annular guide 22 by rotating the limiting adjusting bolt 53, thereby further limiting the displacement caused by the back-and-forth movement of the stirring cylinder 20 and ensuring its normal operation. For example, by limiting the front end face of the front self-lubricating plate 55 to the front end face of the annular guide 22, the front end face of the annular guide 22 does not contact the front end face of the annular groove of the corresponding guide wheel 14, thus making the guide wheel 14 less prone to wear. Correspondingly, the rear self-lubricating plate 55... The front end of the guide plate 50 limits the rear end face of the annular guide 22, preventing the rear end face of the annular guide 22 from contacting the rear end face of the annular groove of the corresponding guide wheel 14. This makes the guide wheel 14 less prone to wear. The wear of the annular groove of the guide wheel 14 is prevented by the wear of the self-lubricating plate 55, thereby reducing maintenance costs. In the future, it is only necessary to open the limiting sleeve 50 and remove and replace the self-lubricating plate 55 fixed on the limiting plate 54 (the self-lubricating plate 55 is fixed to the limiting plate 54 by bolts, making it easy to remove and install).

[0033] Furthermore, a stirring drive motor 15 is fixed on the top surface of one side of the rear frame of the frame 10, and the output shaft of the stirring drive motor 15 is connected and fixed to the rear end of the corresponding transmission shaft 12 through a coupling.

[0034] An upper buffer frame 60 is installed on the top plate of the limiting sleeve 50, and an upper limit guide wheel 61 installed on the lower part of the upper buffer frame 60 presses against the top surface of the middle part of the mixing cylinder 20.

[0035] The upper buffer frame 60 includes a horizontal fixed plate 62. End plates are fixed to the front and rear bottom surfaces of the horizontal fixed plate 62. The two ends of the hinge shaft movably connected to the middle of the upper limit wheel 61 are fixed to the end plates. Two vertical guide rods 63 are fixed to the top surface of the horizontal fixed plate 62. The vertical guide rods 63 are inserted into corresponding through holes formed on the top plate of the limiting sleeve 50. The upper part of the vertical guide rod 63 is formed with external threads. The top of the vertical guide rod 63 extends out of the top of the through hole and is screwed with two mutually pressing adjusting nuts 64. The bottom surface of the lower adjusting nut 64 presses against the top surface of the top plate of the limiting sleeve 50.

[0036] A buffer spring 65 is inserted into the lower part of the vertical guide rod 63. The top end of the buffer spring 65 is attached to the bottom surface of the top plate of the limiting sleeve 50, and the bottom end of the buffer spring 65 is attached to the top surface of the horizontal fixing plate 62.

[0037] The two upper buffer frames 60 are located at the front and rear of the upper part of the outer gear ring 21.

[0038] The above structure enables the stirring drive motor 15 to run, driving the corresponding transmission shaft 12 to rotate, which in turn drives the drive gear 13 to rotate, thus driving the stirring drum 20 to rotate. During rotation, it is supported at three points by the guide wheels 14 on both sides and the upper limit wheel 61, ensuring stable operation. The buffer spring 65 prevents the upper limit wheel 61 from jamming, ensuring the normal rotation of the stirring drum 20. Moreover, the three-point support ensures that the stirring drum 20 can rotate normally even when the stirring speed is increased, without disengaging or jamming, thus meeting the needs of different mixing materials.

[0039] Furthermore, the rear vertical frame 30 includes multiple vertical support rods 31 fixed to the left, right and rear of the top surface of the frame at the rear of the machine frame 10. An inclined plate is fixed to the top surface of all the vertical support rods 31. The rear of the top surface of the inclined plate is higher than the front. An upper fixing block 32 is fixed in the middle of the top surface of the inclined plate. An arc-shaped groove is formed in the middle of the top surface of the upper fixing block 32. The rear end of the arc-shaped groove is higher than the front end. The lower part of the feed hopper 40 is inserted into the arc-shaped groove. Its outer side wall is pressed against the inner side wall of the arc-shaped groove and fixed by welding or bolts. The front end and rear end of the feed hopper 40 extend out of the arc-shaped groove.

[0040] In this embodiment, the limiting sleeve 50 ensures that the mixing cylinder 20 will not fall off when impacted or during operation, thus ensuring safe use and normal operation.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
